Journal articles on the topic 'Self-biased circulator'

The anisotropic hexagonal magnetic material is prepared using conventional ceramic process. The high magnetic anisotropy field of hexagonal is essential to extend the device bandwidth for circulator operating at millimeter wave band. The modified hexagonal BaFe12-xCoxO19 with about 9 kOe anisotropy field and its Electromagnetic property are presented. And a simulation certificating the circulator at Ka-band is given at the end of the paper.

Barium ferrite films were prepared using screen printing method for their applications in self-biased microwave integrated circulators. The influences of alignment magnetic field on the microstructure and magnetic properties of the barium ferrite thick films were investigated. The results show that the (00l) peaks of the barium ferrite films are enhanced with the increase of alignment magnetic field. Hexagonal BaFe 12 O 19 platelets rotate and orient with c-axis perpendicular to the film plane after the magnetic field aligning. The remanence ratio of the barium ferrite films is improved from 0.52 to 0.78 with the increase of alignment magnetic field from 0 to 8 kOe. By magnetic field aligning, barium ferrite thick films with the remanence ratio of 0.8 have been prepared. A prototype of microwave integrated circulator is developed with the prepared barium ferrite films.

M-type barium hexaferrite (BaM) is a promising gyromagnetic material for self-biased microwave\millimeter wave devices because of its large uniaxial magnetocrystalline anisotropy and low microwave loss in high frequency. Due to the limitation of growth conditions, it is difficult to deposit BaM films with enough thickness by PLD, MBE and Magnetron Sputtering for practical application. However, it is demonstrated in present experiment that large area polycrystalline BaM thick films (500μm) with self-biasing (high remanence) and low microwave loss can be successfully fabricated by tape casting. X-ray diffraction and Scanning electron microscopy results indicate that these BaM thick films have highly c-axis oriented crystallographic texture with hexagonal morphology. Magnetic hysteresis loops reveal that samples exhibit excellent properties with a saturate magnetization (4πMs) of 3606G, a high squareness ratio (Mr/Ms) of 0.82. In addition, ferromagnetic resonance (FMR) measurement shows that the FMR linewidth is as small as 431Oe at 48GHz. These parameters ensure these BaM thick films are potentially useful for self-biased microwave\millimeter wave devices such as circulator, phase shifter and filter.

Integration of the ferrite devices in the RF front-end and active antennas is hindered by the need for external magnets, biasing soft microwave ferrites. The hexaferrite-based self-biased nonreciprocal devices can operate without external magnets at mm-wave frequencies but the currently available hexaferrite materials inflict high RF losses at lower frequencies, particularly in the wireless communication bands. In this paper, the parameters of La-Co-substituted hexaferrite compounds are used for the self-biased circulators in the low GHz frequency bands, and a means of the dissipation loss reduction are discussed.

There seems to be no study too fragmented, no hypothesis too trivial, no literature citation too biased or too egotistical, no design too warped, no methodology too bungled, no presentation of results too inaccurate, too obscure, and too contradictory, no analysis too self serving, no argument too circular, no conclusions too trivial, too trifling or too unjustified, and no grammar and syntax too offensive for a paper to end up in print.

Abstract Scholars of Mao-era history adopt a wide range of approaches to the selection and treatment of source material. Some scholars regard published sources as propaganda, and therefore as biased and unreliable. For many, archival sources are the gold standard; others question the reliability even of the archive and favor materials that escaped the filtering fingers of the state to be found in flea markets or garbage piles. Avoiding the false choice of either accepting sources as received wisdom or dismissing them as biased, the author argues that how scholars read their sources is more important than which they keep and which they throw away. She advocates for a layered approach that accounts for contexts of production and circulation, and further emphasizes the need to make this process of reading sources visible in our writing. A critical, layered reading of three unlikely sources demonstrates the myriad possibilities for analysis that combines the empirical, the discursive, and the self-reflexive.

Abstract A variable-resolution atmospheric general circulation model (AGCM) is used for climate change projections over the Antarctic. The present-day simulation uses prescribed observed sea surface conditions, while a set of five simulations for the end of the twenty-first century (2070–99) under the Special Report on Emissions Scenarios (SRES) A1B scenario uses sea surface condition anomalies from selected coupled ocean–atmosphere climate models from phase 3 of the Coupled Model Intercomparison Project (CMIP3). Analysis of the results shows that the prescribed sea surface condition anomalies have a very strong influence on the simulated climate change on the Antarctic continent, largely dominating the direct effect of the prescribed greenhouse gas concentration changes in the AGCM simulations. Complementary simulations with idealized forcings confirm these results. An analysis of circulation changes using self-organizing maps shows that the simulated climate change on regional scales is not principally caused by shifts of the frequencies of the dominant circulation patterns, except for precipitation changes in some coastal regions. The study illustrates that in some respects the use of bias-corrected sea surface boundary conditions in climate projections with a variable-resolution atmospheric general circulation model has some distinct advantages over the use of limited-area atmospheric circulation models directly forced by generally biased coupled climate model output.

An unhealthy diet is strongly linked to obesity and numerous chronic diseases. Currently, over two-thirds of American adults are overweight or obese. Although dietary assessment helps people improve nutrition and lifestyle, traditional methods for dietary assessment depend on self-report, which is inaccurate and often biased. In recent years, as electronics, information, and artificial intelligence (AI) technologies advanced rapidly, image-based objective dietary assessment using wearable electronic devices has become a powerful approach. However, research in this field has been focused on the developments of advanced algorithms to process image data. Few reports exist on the study of device hardware for the particular purpose of dietary assessment. In this work, we demonstrate that, with the current hardware design, there is a considerable risk of missing important dietary data owing to the common use of rectangular image screen and fixed camera orientation. We then present two designs of a new camera system to reduce data loss by generating circular images using rectangular image sensor chips. We also present a mechanical design that allows the camera orientation to be adjusted, adapting to differences among device wearers, such as gender, body height, and so on. Finally, we discuss the pros and cons of rectangular versus circular images with respect to information preservation and data processing using AI algorithms.

Digital nomads (DNs) are independent professionals who rely heavily on digital media and communications, are not bound to the constraints imposed by traditional organizations, and prioritize variables such as cheaper living costs when deciding where to live. Communication technologies enable the emergence of this digital lifestyle that is characterized by high mobility, self-efficacy, location-independent resource-sharing, and minimalism. The immediate outcome of the Covid-19 pandemic created an unprecedented space for debate between the DN community and the mainstream. On the one hand, the mainstream recognized the adaptive advantages of location independence and working remotely; on the other, DNs realized that one of their most fundamental values—the freedom to move—could become compromised by stringent border regulations forcing them to reassess nomadism. This article draws on risk society theories, Maslow’s hierarchy of needs and self-actualization, to approach this problem. We Analyzed content produced by DN creators on YouTube, focusing on risk perceptions and arguments about the choice of staying nomad, compared with the alternative, that is, going back “home” seeking safety: (1) we found that most creators upheld core DN values, rather than shifting to fear-based or risk-control narratives driven by the effects of the pandemic. The narratives circulated in the videos thus contributed to reinforce the community’s values related to self-actualization, in a time of crisis; (2) as a group, the creators we studied were not biased to one option (keep moving or go home) and rather offered strong arguments to support either choice.

PurposeThe purpose of this paper is to investigate whether justice, trust in healthcare services, the confidence level of the health system and institutions, political party support and evaluation of healthcare services post-Jaminan Kesehatan Nasional (JKN) affected policy acceptability (PA) in the health workers (n=95) and laypeople (n=308) sample.Design/methodology/approachThe authors performed a two-level, linear mixed-effects model to test the hypothesis that trust, perceived justice, confidence in healthcare services and national health system evaluation could impact PA in the health workers and laypeople sample. The authors calculated the effect sizes by comparing Level 2 variances and residuals of the null model and the random intercept model.FindingsThe findings suggested that healthcare workers with high concern for justice would be more likely to hold negative acceptability to JKN. The findings implied that health workers tend to associate JKN with unfairness. Also, JKN acceptability in laypeople sample was found to be positively associated with the evaluation of healthcare service post-JKN, whereas justice or political party support did not affect JKN acceptability. It might indicate that laypeople motives for joining JKN scheme could be essentially pragmatic.Research limitations/implicationsThe authors administered the questionnaire using an online platform and circulated it through social media and IMS, so that this research poses a problem of self-selection bias, which potentially leads to biased estimates. The authors also oversampled female participants, especially in laypeople sample.Originality/valueAiming at universal health coverage in 2019, JKN will cover almost 300m Indonesians and be one of the biggest single-payer national health insurance scheme in the world. The research might offer insight into how health workers and laypeople respond to the policy.

The main purpose of the paper is to show how a magnetoresistive (MR) element can work as a current sensor instead of using a Wheatstone bridge composed by four MR elements, defining the concept of a magnetoresistive shunt (MR-shunt). This concept is reached by considering that once the MR element is biased at a constant current, the voltage drop between its terminals offers information, by the MR effect, of the current to be measured, as happens in a conventional shunt resistor. However, an MR-shunt has the advantage of being a non-dissipative shunt since the current of interest does not circulate through the material, preventing its self-heating. Moreover, it provides galvanic isolation. First, we propose an electronic circuitry enabling the utilization of the available MR sensors integrated into a Wheatstone bridge as sensing elements (MR-shunt). This circuitry allows independent characterization of each of the four elements of the bridge. An independently implemented MR element is also analyzed. Secondly, we propose an electronic conditioning circuit for the MR-shunt, which allows both the bridge-integrated element and the single element to function as current sensors in a similar way to the sensing bridge. Third, the thermal variation in the sensitivity of the MR-shunt, and its temperature coefficient, are obtained. An electronic interface is proposed and analyzed for thermal drift compensation of the MR-shunt current sensitivity. With this hardware compensation, temperature coefficients are experimentally reduced from 0.348%/°C without compensation to −0.008%/°C with compensation for an element integrated in a sensor bridge and from 0.474%/°C to −0.0007%/°C for the single element.

Introduction: this paper focuses on the legal problems of applying the artificial intelligence technology when solving socio-economic problems. The convergence of two disruptive technologies – Artificial Intelligence (AI) and Data Science – has created a fundamental transformation of social relations in various spheres of human life. A transformational role was played by classical areas of artificial intelligence such as algorithmic logic, planning, knowledge representation, modeling, autonomous systems, multiagent systems, expert systems (ES), decision support systems (DSS), simulation, pattern recognition, image processing, and natural language processing (NLP), as well as by special areas such as representation learning, machine learning, optimization, statistical modeling, mathematical modeling, data analytics, knowledge discovery, complexity science, computational intelligence, event analysis, behavior analysis, social network analysis, and also deep learning and cognitive computing. The mentioned AI and Big Data technologies are used in various business spheres to simplify and accelerate decision-making of different kinds and significance. At the same time, self-learning algorithms create or reproduce inequalities between participants in circulation, lead to discrimination of all kinds due to algorithmic bias. Purpose: to define the areas and directions of legal regulation of algorithmic bias in the application of artificial intelligence from the legal perspective, based on the analysis of Russian and foreign scientific concepts. Methods: empirical methods of comparison, description, interpretation; theoretical methods of formal and dialectical logic; special scientific methods such as the legal-dogmatic method and the method of interpretation of legal norms. Results: artificial intelligence has many advantages (it allows us to improve creativity, services and lifestyle, to enhance the security, helps in solving various problems), but at the same time it causes numerous concerns due to the harmful effects on individual autonomy, privacy, and fundamental human rights and freedoms. Algorithmic bias exists even when the algorithm developer has no intention to discriminate, and even when the recommendation system does not accept demographic information as input: even in the absence of this information, due to thorough analysis of the similarities between products and users, the algorithm may recommend a product to a very homogeneous set of users. The identified problems and risks of AI bias should be taken into consideration by lawyers and developers and should be mitigated to the fullest extent possible, both when developing ethical principles and requirements and in the field of legal policy and law at the national and supranational levels. The legal community sees the opportunity to solve the problem of algorithmic bias through various kinds of declarations, policies, and standards to be followed in the development, testing, and operation of AI systems. Conclusions: if left unaddressed, biased algorithms could lead to decisions that would have a disparate collective impact on specific groups of people even without the programmer’s intent to make a distinction. The study of the anticipated and unintended consequences of applying AI algorithms is especially necessary today because the current public policy may be insufficient to identify, mitigate, and remedy the effects of such non-obvious bias on participants in legal relations. Solving the issues of algorithmic bias by technical means alone will not lead to the desired results. The world community recognizes the need to introduce standardization and develop ethical principles, which would ensure proper decision-making with the application of artificial intelligence. It is necessary to create special rules that would restrict algorithmic bias. Regardless of the areas where such violations are revealed, they have standard features of unfair behavior of the participants in social relations and can be qualified as violations of human rights or fair competition. Minimization of algorithmic bias is possible through the obligatory introduction into circulation of data in the form that would not allow explicit or implicit segregation of various groups of society, i.e. it should become possible to analyze only data without any explicit attributes of groups, data in their full diversity. As a result, the AI model would be built on the analysis of data from all socio-legal groups of society.

Abstract NADPH dependent oxidase 2 (NOX2) is the founding member of a family of multimeric, oxido-reductase enzymes that catalyze the production of superoxides by transferring a single electron from the cofactor NADPH to molecular oxygen. It is primarily utilized in neutrophils and macrophages to generate copious amount of reactive oxygen species (ROS) to facilitate the neutralization of engulfed particulates during phagocytosis. In sharp contrast to this specialized function however, recent evidence implies a non-phagocytic role for NADPH oxidases in which physiologic levels of ROS generated by these enzymes modulate key signaling proteins and transcription factors to exert profound biological effects. Based on this information we decided to investigate the potential role of NOX2 in normal and leukemic stem cells. Using transgenic NOX2 knock out mice, genetically defined murine models of myeloid leukemia and primary human acute myeloid leukemia (AML) specimens, we show that NOX2 is critical for the proper function of normal and malignant hematopoietic stem cells. In silico analysis using published transcriptional profiles of hematopoietic populations revealed that multiple subunits of the NOX2 complex are expressed at low levels in hematopoietic stem cells (HSCs) and at relatively higher levels in multipotent progenitors (MPPs). Next, we characterized the different hematopoietic compartments from age and sex matched wild type (WT) and transgenic NOX2 knock out (KO) mice. Our studies revealed that in the bone marrow of KO mice, a subset of multipotent progenitor populations (MPP2 & MPP3), which often have biased myelo-erythroid output are markedly expanded relative to their wild type counterparts. Consistently, we found increased levels of granulocytes and monocytes in the peripheral circulation of NOX2 KO mice. To test whether NOX2 has a functional, biological role in the self-renewal of HSCs, we performed competitive transplantation assays using equal numbers of whole BM cells from WT and KO mice to co-repopulate lethally irradiated hosts. Analysis of engrafted mice showed that the contribution from NOX2 KO HSCs was severely compromised in all lineages and developmental stages of hematopoiesis examined. Collectively, these results suggest a critical biological role for NOX2 in maintaining the quiescence and long term self-renewal of HSCs. Similar to normal hematopoiesis, we found out that NOX2 is also widely expressed by functionally defined leukemic stem cells in a murine model of myeloid leukemia generated by expressing the oncogenic translocations BCR-ABL and NUP98-HOXA9. To evaluate the role of NOX2 in leukemogenesis, we established the BCR-ABL/NUP98-HOXA9 model using primitive cells derived from either WT or KO. Intriguingly, NOX2 KO leukemic cells generated a much less aggressive disease upon transplantation into primary and subsequently into secondary recipients. Furthermore, leukemic cells in which NOX2 is suppressed displayed aberrant mitotic activity and altered developmental potential marked by loss of quiescence, enhanced entry into cycle and terminal differentiation. To gain mechanistic insight into the observed phenotype, we isolated leukemic stem cells and performed whole genome expression analysis. The data showed that deficiency of NOX2 leads to downregulation of the cell cycle inhibitor CDKN2C (p18) and robust activation of the granulocyte fate determining transcription factor CEBPε. Thus we conclude that loss of NOX2 impacts leukemogenesis through rewiring of the cell cycle machinery and developmental programs in leukemic stem cells. Finally, we found that in CD34+ primary human AML cells, NOX2 and the other subunits of the complex are abundantly expressed. Furthermore, pharmacologic inhibition of NOX2 with VAS2870, a selective NADPH oxidase inhibitor, reduced the level of ROS and limited the in vitro proliferation and survival of leukemic cells. Next we genetically suppressed the expression of NOX2 in primary human AML cells using sh-RNAs and transplanted these cells into immune compromised mice. Consistent with the murine leukemia, NOX2 knocked down AML cells failed to engraft and expand in vivo. Taken together, our results firmly establish a hitherto unrecognized, prominent regulatory role for NOX2 in the biology of normal and malignant hematopoietic stem cells and imply a potential therapeutic opportunity that can get exploited to treat AML.

Global energy shortage puts stringent demand for energy harvesters capable of transforming external green vibration sources into electrical power. Employing a self-biased magnetoelectric (ME) composite of FeCuNbSiB/Ni/PZT (lead zirconate titanate), a prototype of vibration energy harvester is designed and fabricated. The energy harvester has a circular orbit in which a permanent magnetic cylinder reciprocates once an initial kinetic energy is provided. Upon a vibration signal, like handshaking, movement of the permanent magnetic cylinder causes an alternative magnetic field, which was applied on the ME composite. Via magnetic-force-electrical coupling, the ME composite of FeCuNbSiB/Ni/PZT produces output voltage. Finite element simulation is carried out to reveal the underlying mechanism of the harvester. The analysis shows that a maximum output voltage of 7.63 V can be obtained once an original potential energy is applied for the magnet. In particular, the magnet moves back and forth automatically inside the circular orbit with no need to further apply the energy. The effectiveness of the energy output is experimentally verified. When handshaking the energy harvester, a maximum open-circuit voltage of 5.51 V can be generated. The study offers a solution for power supplying some miniaturized or portable devices, such as small hand set and pedometer.

ABSTRACTMicrowave device engineers continually seek materials advances to improve performance of magnetic components at reduced size and cost. Wherever possible, microstrip or stripline device configurations are adopted in preference to bulky waveguide structures. In radar and communications applications, the nonreciprocal propagation properties of ferrites are essential for realizing phase shifters, circulators, isolators, and power limiters. The introduction of superconductor circuits has led to the development of very low-loss phase shifters and circulators. Recent demonstrations of tuning reciprocal rf permeability by varying the state of magnetization at very low magnetic fields has led to the development of high-speed, high-Q tunable filters. In this paper, design issues of four classes of microwave device are reviewed from the standpoint of their ferrite material requirements: (1) low-loss microstrip phase shifters (2) microstrip tunable resonators, (3) self-biased microstrip circulators with normal or in-plane uniaxial anisotropy, and (4) high-power quasi-optical circulators.

AbstractThis study shows that participants tend to remember an ambiguous, directional cue as biased towards stimuli associated with a high reward that can be attained dishonestly. Participants saw eight digits presented in a circular arrangement. On some trials, they were asked to report the digit (“Target Digit”) indicated by a jittery cue that was slightly biased in the direction of another digit (“Second Cued Digit”), which was either higher or lower than the Target Digit. Participants were paid based on the reported digit (higher digits meant higher pay) and not based on the accuracy of their report. In this setting, they could make self-serving mistakes by dishonestly reporting the Second Cued Digit when it was higher than the Target Digit. Replicating prior work, participants frequently made such self-serving mistakes. On other trials, after the digits disappeared, participants were asked to reproduce the direction of the jittery cue, without receiving any pay. Results showed that that participants’ reports of the cue were more biased toward high-rewarding digits than low-rewarding digits. This research provides preliminary evidence of a link between attention, dishonesty, and memory, offering an important constraint for theories in behavioral ethics.

Patterns in biology can be considered as predetermined or arising from a self-organizing instability. Variability in the pattern can, thus, be interpreted as a trace of instability, growing out from noise. Studying this variability can, thus, hint toward an underlying morphogenetic mechanism. Here, we present the variability of the gastrovascular system of the jellyfish Aurelia. In this variability emerges a typical biased reconnection between canals and time-correlated reconnections. Both phenomena can be interpreted as traces of mechanistic effects, the swimming contractions on the tissue surrounding the gastrovascular canals, and the mean fluid pressure inside them. This reveals the gastrovascular network as a model system to study the morphogenesis of circulation networks and the morphogenetic mechanisms at play.

AbstractThe paper presents an enhanced version of an arc electron source designed for air ionization applications in a self-neutralizing air-breathing plasma thruster. The arc electron source is specifically suited for the air-breathing plasma thruster, as it allows precise control of mean electron energy levels. This paper focuses on the ionization aspects of air-breathing thrusters through the development of axially magnetized arc electron sources. The sources consist of a circular and coaxial configuration of a metallic arc plasma source coupled with a positively biased grid to extract electrons and control mean electron energy. The average mean electron energy of electrons in the arc electron source is regulated by adjusting the bias voltage of the grid within the range of 0 V – 300 V. To investigate the behavior of ion current density and electron density concerning pressure and mean electron energy, the current probe and magnetic filter were utilized. It was demonstrated that the circular electron source leads to enhanced ionization of airflow by achieving plasma densities greater than 1018 m−3. By utilizing a high-speed camera for the circular arc electron source, the arc spot was seen to move azimuthally due to the magnetic field. Furthermore, scanning electron microscopy and a conductance measurement system were employed for the coaxial arc electron source to examine the deposition and conductance of the electron extraction grid. While the grid underwent deposition of about 600 microns, the conductance was observed to increase/saturate with time and bias voltage, indicating an electrically “self-healing material”.

Abstract The sintering temperature is a key way to tune the structural and magnetic properties of M-type hexaferrites. Here the effect of sintering temperature on BaFe9.95Al2Mg0.05O19 M-type hexagonal Ba-hexaferrites was studied. X-ray diffraction analysis revealed the presence of Fe2O3 impurity phases in all samples. The results showed that as the sintering temperature increased, the saturation magnetization and remanence ratio initially increased, then decreased at higher temperatures. On the other hand, the coercivity and magnetocrystalline anisotropy field decreased first, then increased. The morphology suggested that average grain size consistently grew between 800-2800 nm with increasing temperature. The optimal magnetic properties of BaFe9.95Al2Mg0.05O19 were achieved at a sintering temperature of 1280 ℃, with saturation magnetization 49.94 emu/g, coercivity 4.99 kOe, anisotropic field 1.5kOe, and magnetic moment of 9.4097µB. The findings suggest that the magnetic properties of M-type hexagonal ferrites can be significantly enhanced by optimizing the sintering temperature, which has implications for the development of high-performance self-biased circulators, Magnetic filters, and other magnetic applications.

Purpose: The purpose of this clinical focus article is to present an innovative language intervention program for adolescents that attempts to build critical thinking skills by addressing logical fallacies. Method: Fourteen logical fallacies that often occur in spoken and written discourse are defined and discussed. These include the hasty generalization , the false dichotomy , equivocation , circular reasoning , the anecdote , the appeal to hypocrisy , the slippery slope , the appeal to ridicule , the red herring , the bandwagon , the false cause , the omission of evidence , the appeal to authority , and ad hominem . The consequences of passively accepting biased, illogical, and inaccurate statements are highlighted, and ways to address these concerns are explained. Results: Given their expertise in spoken and written language development and disorders, speech-language pathologists, collaborating with classroom teachers, are well suited to teach adolescents with developmental language disorder or weak language skills how to unlock—or deconstruct—logical fallacies to reveal their hidden meaning. All of this can be achieved while addressing students' basic competencies in speaking, listening, reading, and writing—skills that are essential for well-informed and self-reliant thinking. Conclusion: In addition to helping students manage their own lives more successfully and to communicate more effectively, instruction in critical thinking by unlocking logical fallacies may help to increase levels of social justice in our institutions and daily interactions over time.

ABSTRACT Lipid nanoparticle (LNP)-encapsulated mRNAs have emerged as effective vaccination tools to stimulate immunity. The most common application of this technology is to deliver mRNAs that encode antigenic proteins to dendritic cells (DCs), which then stimulate antigen-specific lymphocyte responses. It is unclear whether other immunostimulatory DC activities necessary for vaccine efficacy, beyond antigen presentation, can be induced via mRNA-encoded proteins. Herein, we report an mRNA encoding a self-DNA reactive variant of the enzyme cyclic GMP-AMP synthase (cGAS), known as cGAS∆N. cGAS∆N produces the cyclic dinucleotide cGAMP upon binding intra-mitochondrial DNA. cGAMP binds the protein STING, which activates innate immune responses that stimulate T cells. We found that when delivered to DCs via LNPs, mRNA-encoded cGAS∆N induced the upregulation of chemokine receptors, T cell costimulatory molecules, major histocompatibility complex proteins, pro-inflammatory cytokines and type I interferons from murine and human DCs. These activities exceeded the immunostimulatory activities of mRNA-encoded antigens delivered via LNPs. Co-immunization of mice with antigen-LNPs and cGAS∆N-LNPs led to the robust production of antigen-specific IFNγ-producing T cells. These T cell responses were durable and circulated through the lymphatics, blood, and lungs. Immunizations with antigen-LNPs alone, akin to what are used in the clinic, stimulated weak and transient T cell responses. Antibody responses to antigen-LNPs were biased towards type I isotypes when co-injected with cGAS∆N-LNPs, as compared to immunizations with antigen-LNPs alone. These findings establish the enzyme cGAS∆N as a catalytic adjuvant, which may prove useful in enhancing the immunogenicity of nucleic acid-based vaccines. IMPORTANCE Nucleic acid-based vaccines hold promise in preventing infections and treating cancer. The most common use of this technology is to encode antigenic proteins on mRNAs that are delivered to cells via lipid nanoparticle (LNP) formulations. In this study, we discovered that immunostimulatory proteins can also be encoded on mRNAs in LNPs. We found that an active mutant of the enzyme cGAS, referred to as cGAS∆N, acts as a catalytic adjuvant in LNP-encapsulated mRNA vaccines. The delivery of cGAS∆N mRNA via LNPs in combination with antigen mRNA-LNPs led to durable antigen-specific IFNγ-producing T cells that exceeded the efficiency of antigen-LNPs similar to those currently used in the clinic. This strategy did not compromise B cell responses; rather it induced Th1-biased antibody isotypes. This work unveils new vaccine design strategies using mRNA-encoded catalytic adjuvants that could be ideal for generating CD8 + T cell and B cell responses for immunotherapies.

Susheel Kumar Sharma’s Unwinding Self: A Collection of Poems. Cuttack: Vishvanatha Kaviraj Institute, 2020, ISBN: 978-81-943450-3-9, Paperback, pp. viii + 152. Like his earlier collection, The Door is Half Open, Susheel Kumar Sharma’s Unwinding Self: A Collection of Poems has three sections consisting of forty-two poems of varied length and style, a detailed Glossary mainly on the proper nouns from Indian culture and tradition and seven Afterwords from the pens of the trained readers from different countries of four continents. The structure of the book is circular. The first poem “Snapshots” indicates fifteen kaleidoscopic patterns of different moods of life in about fifteen words each. It seems to be a rumination on the variegated images of everyday experiences ranging from individual concerns to spiritual values. Art-wise, they can be called mini-micro-poems as is the last poem of the book. While the character limit in a micro poem is generally 140 (the character limit on Twitter) Susheel has used just around 65 in each of these poems. Naturally, imagery, symbolism and cinematic technique play a great role in this case. In “The End of the Road” the poet depicts his individual experiences particularly changing scenario of the world. He seems to be worried about his eyesight getting weak with the passage of time, simultaneously he contrasts the weakness of his eyesight with the hypocrisy permeating the human life. He compares his diminishing eyesight to Milton and shows his fear as if he will get blind. He changes his spectacles six times to clear his vision and see the plurality of a reality in human life. It is an irony on the changing aspects of human life causing miseries to the humanity. At the end of the poem, the poet admits the huge changes based on the sham principles: “The world has lost its original colour” (4). The concluding lines of the poem make a mockery of the people who are not able to recognise reality in the right perspective. The poem “Durga Puja in 2013” deals with the celebration of the festival “Durga Puja” popular in the Hindu religion. The poet’s urge to be with Ma Durga shows his dedication towards the Goddess Durga, whom he addresses with different names like ‘Mai’, ‘Ma’ and ‘Mother’. He worships her power and expresses deep reverence for annihilating the evil-spirits. The festival Durga Puja also reminds people of victory of the goddess on the elusive demons in the battlefield. “Chasing a Dream on the Ganges” is another poem having spiritual overtones. Similarly, the poem “Akshya Tritya” has religious and spiritual connotations. It reflects curiosity of people for celebration of “Akshya Tritya” with enthusiasm. But the political and economic overtones cannot be ignored as the poem ends with the remarkable comments: The GDP may go up on this day; Even, Budia is able to Eat to his fill; Panditji can blow his Conch shell with full might. Outside, somebody is asking for votes; Somebody is urging others to vote. I shall vote for Akshya Tritya. (65-66) “On Reading Langston Hughes’ ‘Theme for English B’” is a long poem in the collection. In this poem, the poet reveals a learner’s craving for learning, perhaps who comes from an extremely poor background to pursue his dreams of higher education. The poet considers the learner’s plights of early childhood, school education and evolutionary spirit. He associates it with Dronacharya and Eklavya to describe the mythical system of education. He does not want to be burdened with the self-guilt by denying the student to be his ‘guru’ therefore, he accepts the challenge to change his life. Finally, he shows his sympathy towards the learner and decides to be the ‘guru’: “It is better to face/A challenge and change/Than to be burden with a life/Of self-guilt. /I put my signatures on his form willy-nilly” (11). The poem “The Destitute” is an ironical presentation of the modern ways of living seeking pleasure in the exotic locations all over the world. It portrays the life of a person who has to leave his motherland for earning his livelihood, and has to face an irreparable loss affecting moral virtues, lifestyle, health and sometimes resulting in deaths. The poem “The Black Experience” deals with the suppression of the Africans by the white people. The poem “Me, A Black Doxy”, perhaps points out the dilemma of a black woman whether she should prostitute herself or not, to earn her livelihood. Perhaps, her deep consciousness about her self-esteem does not allow her to indulge in it but she thinks that she is not alone in objectifying herself for money in the street. Her voice resonates repeatedly with the guilt of her indulgence on the filthy streets: At the dining time Me not alone? In the crowded street Me not alone? They ’ave white, grey, pink hair Me ’ave black hair – me not alone There’s a crowd with black hair. Me ’ave no black money Me not alone? (14) The poem “Thus Spake a Woman” is structured in five sections having expressions of the different aspects of a woman’s love designs. It depicts a woman’s dreams and her attraction towards her lover. The auditory images like “strings of a violin”, “music of the violin” and “clinch in my fist” multiply intensity of her feelings. With development of the poem, her dreams seem to be shattered and sadness know the doors of her dreamland. Finally, she is confronted with sadness and is taken back to the past memories reminding her of the difficult situations she had faced. Replete with poetic irony, “Bubli Poems” presents the journey of a female, who, from the formative years of her life to womanhood, experienced gender stereotypes, biased sociocultural practices, and ephemeral happiness on the faces of other girls around her. The poem showcases the transformation of a village girl into a New Woman, who dreams her existence in all types of luxurious belongings rather than identifying her independent existence and finding out her own ways of living. Her dreams lead her to social mobility through education, friendships, and the freedom that she gains from her parents, family, society and culture. She attempts her luck in the different walks of human life, particularly singing and dancing and imagines her social status and wide popularity similar to those of the famous Indian actresses viz. Katrina and Madhuri Dixit: “One day Bubli was standing before the mirror/Putting on a jeans and jacket and shaking her hips/She was trying to be a local Katrina” (41). She readily bears the freakish behaviour of the rustic/uncultured lads, derogatory comments, and physical assaults in order to fulfil her expectations and achieves her individual freedom. Having enjoyed all the worldly happiness and fashionable life, ultimately, she is confronted with the evils designs around her which make her worried, as if she is ignorant of the world replete with the evils and agonies: “Bubli was ignorant of her agony and the lost calm” (42). The examples of direct poetic irony and ironic expressions of the socio-cultural evils, and the different governing bodies globally, are explicit in this poem: “Bubli is a leader/What though if a cheerleader./The news makes her family happy.”(40), “Others were blaming the Vice-Chancellor/ Some others the system;/ Some the freedom given to girls;”(45), and “Some blame poverty; some the IMF;/ Some the UN; some the environment;/ Some the arms race; some the crony’s lust;/ Some the US’s craving for power;/Some the UK’s greed. (46-47). Finally, Bubli finds that her imaginative world is fragile. She gives up her corporeal dreams which have taken the peace of her mind away. She yearns for shelter in the temples and churches and surrenders herself before deities praying for her liberation: “Jai Kali,/ Jai Mahakali, Jai Ma, Jai Jagaddhatri,/ Save me, save the world.” (47). In the poem “The Unlucky”, the poet jibes at those who are lethargic in reading. He identifies four kinds of readers and places himself in the fourth category by rating himself a ‘poor’ reader. The first three categories remind the readers of William Shakespeare’s statement “Some are born great, some achieve greatness, and some have greatness thrust upon them.” At the end of the poem, the poet questions himself for being a poet and teacher. The question itself reflects on his ironic presentation of himself as a poor reader because a poet’s wisdom is compared with that of the philosopher and everybody worships and bows before a teacher, a “guru”, in the Indian tradition. The poet is considered the embodiment of both. The poet’s unfulfilled wish to have been born in Prayagraj is indexed with compunction when the poem ends with the question “Why was I not born in Prayagraj?” (52). Ending with a question mark, the last line of the poem expresses his desire for perfection. The next poem, “Saying Goodbye”, is elegiac in tone and has an allusion to Thomas Gray’s “The Elegy Written in a Country Churchyard” in the line “When the curfew tolls the knell of the parting day”; it ends with a question mark. The poem seems to be a depiction of the essence and immortality of ‘time’. Reflecting on the poet’s consideration of the power and beauty of ‘time’, Pradeep Kumar Patra rightly points out, “It is such a phenomena that nobody can turn away from it. The moment is both beautiful as well as ferocious. It beautifies and showcases everything and at the same time pulls everything down when necessary” (146). Apparently, the poem “The Kerala Flood 2018”is an expression of emotions at the disaster caused by the flood in 2018. By reminding of Gandhi’s tenets to be followed by people for the sake of morality and humankind, the poet makes an implicit criticism of the pretentions, and violation of pledges made by people to care of other beings, particularly, cow that is worshiped as “mother” and is considered to be a symbol of fertility, peace and holiness in Hinduism as well as the Buddhist culture. The poet also denigrates people who deliberately ignore the sanctity of the human life in Hinduism and slaughter the animal cow to satisfy their appetites. In the poem, the carnivorous are criticized explicitly, but those who pretend to be herbivorous are decried as shams: If a cow is sacrosanct And people eat beef One has to take a side. Some of the friends chose to Side with cow and others With the beef-eaters. Some were more human They chose both. (55) The poet infuses positivity into the minds of the Indian people. Perhaps, he thinks that, for Indians, poverty, ignorance, dirt and mud are not taboos as if they are habitual to forbear evils by their instincts. They readily accept them and live their lives happily with pride considering their deity as the preserver of their lives. The poem “A Family by the Road” is an example of such beliefs, in which the poet lavishes most of his poetic depiction on the significance of the Lord Shiva, the preserver of people in Hinduism: Let me enjoy my freedom. I am proud of my poverty. I am proud of my ignorance. I am proud of my dirt. I have a home because of these. I am proud of my home. My future is writ on the walls Of your houses My family shall stay in the mud. After all, somebody is needed To clean the dirt as well. I am Shiva, Shivoham. (73) In the poem “Kabir’s Chadar”, the poet invokes several virtues to back up his faith in spirituality and simplicity. He draws a line of merit and virtue between Kabir’s Chadar which is ‘white’ and his own which is “thickly woven” and “Patterned with various beautiful designs/ In dark but shining colours” (50). The poet expresses his views on Kabir’s ‘white’ Chadar symbolically to inculcate the sense of purity, fortitude, spirituality, and righteousness among people. The purpose of his direct comparison between them is to refute artificiality, guilt and evil intents of humanity, and propagate spiritual purity, the stark simplicities of our old way of life, and follow the patience of a saint like Kabir. The poem “Distancing” is a statement of poetic irony on the city having two different names known as Bombay and Mumbai. The poet sneers at its existence in Atlas. Although the poet portraits the historical events jeering at the distancing between the two cities as if they are really different, yet the poet’s prophetic anticipation about the spread of the COVID-19 in India cannot be denied prima facie. The poet’s overwhelming opinions on the overcrowded city of Bombay warn humankind to rescue their lives. Even though the poem seems to have individual expressions of the poet, leaves a message of distancing to be understood by the people for their safety against the uneven things. The poem “Crowded Locals” seems to be a sequel to the poem “Distancing”. Although the poet’s purpose, and appeal to the commonplace for distancing cannot be affirmed by the readers yet his remarks on the overcrowded cities like in Mumbai (“Crowded Locals”), foresee some risk to the humankind. In the poem “Crowded Locals”, he details the mobility of people from one place to another, having dreams in their eyes and puzzles in their minds for their livelihood while feeling insecure especially, pickpockets, thieves and strangers. The poet also makes sneering comments on the body odour of people travelling in first class. However, these two poems have become a novel contribution for social distancing to fight against the COVID-19. In the poem “Buy Books, Not Diamonds” the poet makes an ironical interpretation of social anarchy, political upheaval, and threat of violence. In this poem, the poet vies attention of the readers towards the socio-cultural anarchy, especially, anarchy falls on the academic institutions in the western countries where capitalism, aristocracy, dictatorship have armed children not with books which inculcate human values but with rifles which create fear and cause violence resulting in deaths. The poet’s perplexed opinions find manifestation in such a way as if books have been replaced with diamonds and guns, therefore, human values are on the verge of collapse: “Nine radiant diamonds are no match/ To the redness of the queen of spades. . . . / … holding/ Rifles is a better option than/ Hawking groundnuts on the streets?” (67).The poet also decries the spread of austere religious practices and jihadist movement like Boko Haram, powerful personalities, regulatory bodies and religious persons: “Boko Haram has come/Obama has also come/The UN has come/Even John has come with/Various kinds of ointments” (67). The poem “Lost Childhood” seems to be a memoir in which the poet compares the early life of an orphan with the child who enjoys early years of their lives under the safety of their parents. Similarly, the theme of the poem “Hands” deals with the poet’s past experiences of the lifestyle and its comparison to the present generation. The poet’s deep reverence for his parents reveals his clear understanding of the ways of living and human values. He seems to be very grateful to his father as if he wants to make his life peaceful by reading the lines of his palms: “I need to read the lines in his palm” (70). In the poem “A Gush of Wind”, the poet deliberates on the role of Nature in our lives. The poem is divided into three sections, perhaps developing in three different forms of the wind viz. air, storm, and breeze respectively. It is structured around the significance of the Nature. In the first section, the poet lays emphasis on the air we breathe and keep ourselves fresh as if it is a panacea. The poet criticizes artificial and material things like AC. In the second section, he depicts the stormy nature of the wind scattering papers, making the bed sheets dusty affecting or breaking the different types of fragile and luxurious objects like Italian carpets and lamp shades with its strong blow entering the oriels and window panes of the houses. Apparently, the poem may be an individual expression, but it seems to be a caricature on the majesty of the rich people who ignore the use of eco-chic objects and disobey the Nature’s behest. In the third and the last section of the poem, the poet’s tone is critical towards Whitman, Pushkin and Ginsberg for their pseudoscientific philosophy of adherence to the Nature. Finally, he opens himself to enjoy the wind fearlessly. The poems like “A Voice” , “The New Year Dawn”, “The New Age”, “The World in Words in 2015”, “A Pond Nearby”, “Wearing the Scarlet Letter ‘A’”, “A Mock Drill”, “Strutting Around”, “Sahibs, Snobs, Sinners”, “Endless Wait”, “The Soul with a New Hat”, “Renewed Hope”, “Like Father, Unlike Son”, “Hands”, “Rechristening the City”, “Coffee”, “The Unborn Poem”, “The Fountain Square”, “Ram Setu”, and “Connaught Place” touch upon the different themes. These poems reveal poet’s creativity and unique features of his poetic arts and crafts. The last poem of the collection “Stories from the Mahabharata” is written in twenty-five stanzas consisting of three lines each. Each stanza either describes a scene or narrates a story from the Mahabharata, the source of the poem. Every stanza has an independent action verb to describe the actions of different characters drawn from the Mahabharata. Thus, each stanza is a complete miniscule poem in itself which seems to be a remarkable characteristic of the poem. It is an exquisite example of ‘Micro-poetry’ on paper, remarkable for its brevity, dexterity and intensity. The poet’s conscious and brilliant reframing of the stories in his poem sets an example of a new type of ‘Found Poetry’ for his readers. Although the poet’s use of various types images—natural, comic, tragic, childhood, horticultural, retains the attention of readers yet the abundant evidences of anaphora reflect redundancy and affect the readers’ concentration and diminishes their mental perception, for examples, pronouns ‘her’ and ‘we’ in a very small poem “Lost Childhood”, articles ‘the’ and ‘all’ in “Crowded Locals”, the phrase ‘I am proud of’ in “A Family by the Road” occur many times. Svitlana Buchatska’s concise but evaluative views in her Afterword to Unwinding Self help the readers to catch hold of the poet’s depiction of his emotions. She writes, “Being a keen observer of life he vividly depicts people’s life, traditions and emotions involving us into their rich spiritual world. His poems are the reflection on the Master’s world of values, love to his family, friends, students and what is more, to his beloved India. Thus, the author reveals all his beliefs, attitudes, myths and allusions which are the patterns used by the Indian poets” (150). W. H. Auden defines poetry as “the clear expression of mixed feelings.” It seems so true of Susheel Sharma’s Unwinding Self. It is a mixture of poems that touch upon the different aspects of human life. It can be averred that the collection consists of the poet’s seamless efforts to delve into the various domains of the human life and spot for the different places as well. It is a poetic revue in verse in which the poet instils energy, confidence, power and enthusiasm into minds of Indian people and touches upon all aspects of their lives. The poverty, ignorance, dirt, mud, daily struggle against liars, thieves, pickpockets, touts, politician and darkness have been depicted not as weaknesses of people in Indian culture but their strengths, because they have courage to overcome darkness and see the advent of a new era. The poems teach people morality, guide them to relive their pains and lead them to their salvation. Patricia Prime’s opinion is remarkable: “Sharma writes about his family, men and women, childhood, identity, roots and rootlessness, memory and loss, dreams and interactions with nature and place. His poised, articulate poems are remarkable for their wit, conversational tone and insight” (138). Through the poems in the collection, the poet dovetails the niceties of the Indian culture, and communicates its beauty and uniqueness meticulously. The language of the poem is lucid, elevated and eloquent. The poet’s use of diction seems to be very simple and colloquial like that of an inspiring teacher. On the whole the book is more than just a collection of poems as it teaches the readers a lot about the world around them through a detailed Glossary appended soon after the poems in the collection. It provides supplementary information about the terms used abundantly in Indian scriptures, myths, and other religious and academic writings. The Glossary, therefore, plays pivotal role in unfolding the layers of meaning and reaching the hearts of the global readers. The “Afterwords” appended at the end, enhances readability of poems and displays worldwide acceptability, intelligibility, and popularity of the poet. The Afterwords are a good example of authentic Formalistic criticism and New Criticism. They indirectly teach a formative reader and critic the importance of forming one’s opinion, direct reading and writing without any crutches of the critics.

Although I'm a rich white guy, I'm also a feminist anti-racism activist who fights for the rights of the poor and oppressed. (Carl Kenner)Systemic bias is a scourge to the pillar of neutrality. (Cerejota)Count me in. Let's leave the bias to the mainstream media. (Orcar967)Because this is so important. (CuttingEdge)These are a handful of comments posted by online editors who have banded together in a virtual coalition to combat Western bias on the world’s largest digital encyclopedia, Wikipedia. This collective action by Wikipedians both acknowledges the inherent inequalities of a user-controlled information project like Wikpedia and highlights the potential for progressive change within that same project. These community members are taking the responsibility of social change into their own hands (or more aptly, their own keyboards).In recent years much research has emerged on Wikipedia from varying fields, ranging from computer science, to business and information systems, to the social sciences. While critical at times of Wikipedia’s growth, governance, and influence, most of this work observes with optimism that barriers to improvement are not firmly structural, but rather they are socially constructed, leaving open the possibility of important and lasting change for the better.WikiProject: Countering Systemic Bias (WP:CSB) considers one such collective effort. Close to 350 editors have signed on to the project, which began in 2004 and itself emerged from a similar project named CROSSBOW, or the “Committee Regarding Overcoming Serious Systemic Bias on Wikipedia.” As a WikiProject, the term used for a loose group of editors who collaborate around a particular topic, these editors work within the Wikipedia site and collectively create a social network that is unified around one central aim—representing the un- and underrepresented—and yet they are bound by no particular unified set of interests. The first stage of a multi-method study, this paper looks at a snapshot of WP:CSB’s activity from both content analysis and social network perspectives to discover “who” geographically this coalition of the unrepresented is inserting into the digital annals of Wikipedia.Wikipedia and WikipediansDeveloped in 2001 by Internet entrepreneur Jimmy Wales and academic Larry Sanger, Wikipedia is an online collaborative encyclopedia hosting articles in nearly 250 languages (Cohen). The English-language Wikipedia contains over 3.2 million articles, each of which is created, edited, and updated solely by users (Wikipedia “Welcome”). At the time of this study, Alexa, a website tracking organisation, ranked Wikipedia as the 6th most accessed site on the Internet. Unlike the five sites ahead of it though—Google, Facebook, Yahoo, YouTube (owned by Google), and live.com (owned by Microsoft)—all of which are multibillion-dollar businesses that deal more with information aggregation than information production, Wikipedia is a non-profit that operates on less than $500,000 a year and staffs only a dozen paid employees (Lih). Wikipedia is financed and supported by the WikiMedia Foundation, a charitable umbrella organisation with an annual budget of $4.6 million, mainly funded by donations (Middleton).Wikipedia editors and contributors have the option of creating a user profile and participating via a username, or they may participate anonymously, with only an IP address representing their actions. Despite the option for total anonymity, many Wikipedians have chosen to visibly engage in this online community (Ayers, Matthews, and Yates; Bruns; Lih), and researchers across disciplines are studying the motivations of these new online collectives (Kane, Majchrzak, Johnson, and Chenisern; Oreg and Nov). The motivations of open source software contributors, such as UNIX programmers and programming groups, have been shown to be complex and tied to both extrinsic and intrinsic rewards, including online reputation, self-satisfaction and enjoyment, and obligation to a greater common good (Hertel, Niedner, and Herrmann; Osterloh and Rota). Investigation into why Wikipedians edit has indicated multiple motivations as well, with community engagement, task enjoyment, and information sharing among the most significant (Schroer and Hertel). Additionally, Wikipedians seem to be taking up the cause of generativity (a concern for the ongoing health and openness of the Internet’s infrastructures) that Jonathan Zittrain notably called for in The Future of the Internet and How to Stop It. Governance and ControlAlthough the technical infrastructure of Wikipedia is built to support and perhaps encourage an equal distribution of power on the site, Wikipedia is not a land of “anything goes.” The popular press has covered recent efforts by the site to reduce vandalism through a layer of editorial review (Cohen), a tightening of control cited as a possible reason for the recent dip in the number of active editors (Edwards). A number of regulations are already in place that prevent the open editing of certain articles and pages, such as the site’s disclaimers and pages that have suffered large amounts of vandalism. Editing wars can also cause temporary restrictions to editing, and Ayers, Matthews, and Yates point out that these wars can happen anywhere, even to Burt Reynold’s page.Academic studies have begun to explore the governance and control that has developed in the Wikipedia community, generally highlighting how order is maintained not through particular actors, but through established procedures and norms. Konieczny tested whether Wikipedia’s evolution can be defined by Michels’ Iron Law of Oligopoly, which predicts that the everyday operations of any organisation cannot be run by a mass of members, and ultimately control falls into the hands of the few. Through exploring a particular WikiProject on information validation, he concludes:There are few indicators of an oligarchy having power on Wikipedia, and few trends of a change in this situation. The high level of empowerment of individual Wikipedia editors with regard to policy making, the ease of communication, and the high dedication to ideals of contributors succeed in making Wikipedia an atypical organization, quite resilient to the Iron Law. (189)Butler, Joyce, and Pike support this assertion, though they emphasise that instead of oligarchy, control becomes encapsulated in a wide variety of structures, policies, and procedures that guide involvement with the site. A virtual “bureaucracy” emerges, but one that should not be viewed with the negative connotation often associated with the term.Other work considers control on Wikipedia through the framework of commons governance, where “peer production depends on individual action that is self-selected and decentralized rather than hierarchically assigned. Individuals make their own choices with regard to resources managed as a commons” (Viegas, Wattenberg and McKeon). The need for quality standards and quality control largely dictate this commons governance, though interviewing Wikipedians with various levels of responsibility revealed that policies and procedures are only as good as those who maintain them. Forte, Larco, and Bruckman argue “the Wikipedia community has remained healthy in large part due to the continued presence of ‘old-timers’ who carry a set of social norms and organizational ideals with them into every WikiProject, committee, and local process in which they take part” (71). Thus governance on Wikipedia is a strong representation of a democratic ideal, where actors and policies are closely tied in their evolution. Transparency, Content, and BiasThe issue of transparency has proved to be a double-edged sword for Wikipedia and Wikipedians. The goal of a collective body of knowledge created by all—the “expert” and the “amateur”—can only be upheld if equal access to page creation and development is allotted to everyone, including those who prefer anonymity. And yet this very option for anonymity, or even worse, false identities, has been a sore subject for some in the Wikipedia community as well as a source of concern for some scholars (Santana and Wood). The case of a 24-year old college dropout who represented himself as a multiple Ph.D.-holding theology scholar and edited over 16,000 articles brought these issues into the public spotlight in 2007 (Doran; Elsworth). Wikipedia itself has set up standards for content that include expectations of a neutral point of view, verifiability of information, and the publishing of no original research, but Santana and Wood argue that self-policing of these policies is not adequate:The principle of managerial discretion requires that every actor act from a sense of duty to exercise moral autonomy and choice in responsible ways. When Wikipedia’s editors and administrators remain anonymous, this criterion is simply not met. It is assumed that everyone is behaving responsibly within the Wikipedia system, but there are no monitoring or control mechanisms to make sure that this is so, and there is ample evidence that it is not so. (141) At the theoretical level, some downplay these concerns of transparency and autonomy as logistical issues in lieu of the potential for information systems to support rational discourse and emancipatory forms of communication (Hansen, Berente, and Lyytinen), but others worry that the questionable “realities” created on Wikipedia will become truths once circulated to all areas of the Web (Langlois and Elmer). With the number of articles on the English-language version of Wikipedia reaching well into the millions, the task of mapping and assessing content has become a tremendous endeavour, one mostly taken on by information systems experts. Kittur, Chi, and Suh have used Wikipedia’s existing hierarchical categorisation structure to map change in the site’s content over the past few years. Their work revealed that in early 2008 “Culture and the arts” was the most dominant category of content on Wikipedia, representing nearly 30% of total content. People (15%) and geographical locations (14%) represent the next largest categories, while the natural and physical sciences showed the greatest increase in volume between 2006 and 2008 (+213%D, with “Culture and the arts” close behind at +210%D). This data may indicate that contributing to Wikipedia, and thus spreading knowledge, is growing amongst the academic community while maintaining its importance to the greater popular culture-minded community. Further work by Kittur and Kraut has explored the collaborative process of content creation, finding that too many editors on a particular page can reduce the quality of content, even when a project is well coordinated.Bias in Wikipedia content is a generally acknowledged and somewhat conflicted subject (Giles; Johnson; McHenry). The Wikipedia community has created numerous articles and pages within the site to define and discuss the problem. Citing a survey conducted by the University of Würzburg, Germany, the “Wikipedia:Systemic bias” page describes the average Wikipedian as:MaleTechnically inclinedFormally educatedAn English speakerWhiteAged 15-49From a majority Christian countryFrom a developed nationFrom the Northern HemisphereLikely a white-collar worker or studentBias in content is thought to be perpetuated by this demographic of contributor, and the “founder effect,” a concept from genetics, linking the original contributors to this same demographic has been used to explain the origins of certain biases. Wikipedia’s “About” page discusses the issue as well, in the context of the open platform’s strengths and weaknesses:in practice editing will be performed by a certain demographic (younger rather than older, male rather than female, rich enough to afford a computer rather than poor, etc.) and may, therefore, show some bias. Some topics may not be covered well, while others may be covered in great depth. No educated arguments against this inherent bias have been advanced.Royal and Kapila’s study of Wikipedia content tested some of these assertions, finding identifiable bias in both their purposive and random sampling. They conclude that bias favoring larger countries is positively correlated with the size of the country’s Internet population, and corporations with larger revenues work in much the same way, garnering more coverage on the site. The researchers remind us that Wikipedia is “more a socially produced document than a value-free information source” (Royal & Kapila).WikiProject: Countering Systemic BiasAs a coalition of current Wikipedia editors, the WikiProject: Countering Systemic Bias (WP:CSB) attempts to counter trends in content production and points of view deemed harmful to the democratic ideals of a valueless, open online encyclopedia. WP:CBS’s mission is not one of policing the site, but rather deepening it:Generally, this project concentrates upon remedying omissions (entire topics, or particular sub-topics in extant articles) rather than on either (1) protesting inappropriate inclusions, or (2) trying to remedy issues of how material is presented. Thus, the first question is "What haven't we covered yet?", rather than "how should we change the existing coverage?" (Wikipedia, “Countering”)The project lays out a number of content areas lacking adequate representation, geographically highlighting the dearth in coverage of Africa, Latin America, Asia, and parts of Eastern Europe. WP:CSB also includes a “members” page that editors can sign to show their support, along with space to voice their opinions on the problem of bias on Wikipedia (the quotations at the beginning of this paper are taken from this “members” page). At the time of this study, 329 editors had self-selected and self-identified as members of WP:CSB, and this group constitutes the population sample for the current study. To explore the extent to which WP:CSB addressed these self-identified areas for improvement, each editor’s last 50 edits were coded for their primary geographical country of interest, as well as the conceptual category of the page itself (“P” for person/people, “L” for location, “I” for idea/concept, “T” for object/thing, or “NA” for indeterminate). For example, edits to the Wikipedia page for a single person like Tony Abbott (Australian federal opposition leader) were coded “Australia, P”, while an edit for a group of people like the Manchester United football team would be coded “England, P”. Coding was based on information obtained from the header paragraphs of each article’s Wikipedia page. After coding was completed, corresponding information on each country’s associated continent was added to the dataset, based on the United Nations Statistics Division listing.A total of 15,616 edits were coded for the study. Nearly 32% (n = 4962) of these edits were on articles for persons or people (see Table 1 for complete coding results). From within this sub-sample of edits, a majority of the people (68.67%) represented are associated with North America and Europe (Figure A). If we break these statistics down further, nearly half of WP:CSB’s edits concerning people were associated with the United States (36.11%) and England (10.16%), with India (3.65%) and Australia (3.35%) following at a distance. These figures make sense for the English-language Wikipedia; over 95% of the population in the three Westernised countries speak English, and while India is still often regarded as a developing nation, its colonial British roots and the emergence of a market economy with large, technology-driven cities are logical explanations for its representation here (and some estimates make India the largest English-speaking nation by population on the globe today).Table A Coding Results Total Edits 15616 (I) Ideas 2881 18.45% (L) Location 2240 14.34% NA 333 2.13% (T) Thing 5200 33.30% (P) People 4962 31.78% People by Continent Africa 315 6.35% Asia 827 16.67% Australia 175 3.53% Europe 1411 28.44% NA 110 2.22% North America 1996 40.23% South America 128 2.58% The areas of the globe of main concern to WP:CSB proved to be much less represented by the coalition itself. Asia, far and away the most populous continent with more than 60% of the globe’s people (GeoHive), was represented in only 16.67% of edits. Africa (6.35%) and South America (2.58%) were equally underrepresented compared to both their real-world populations (15% and 9% of the globe’s population respectively) and the aforementioned dominance of the advanced Westernised areas. However, while these percentages may seem low, in aggregate they do meet the quota set on the WP:CSB Project Page calling for one out of every twenty edits to be “a subject that is systematically biased against the pages of your natural interests.” By this standard, the coalition is indeed making headway in adding content that strategically counterbalances the natural biases of Wikipedia’s average editor.Figure ASocial network analysis allows us to visualise multifaceted data in order to identify relationships between actors and content (Vego-Redondo; Watts). Similar to Davis’s well-known sociological study of Southern American socialites in the 1930s (Scott), our Wikipedia coalition can be conceptualised as individual actors united by common interests, and a network of relations can be constructed with software such as UCINET. A mapping algorithm that considers both the relationship between all sets of actors and each actor to the overall collective structure produces an image of our network. This initial network is bimodal, as both our Wikipedia editors and their edits (again, coded for country of interest) are displayed as nodes (Figure B). Edge-lines between nodes represents a relationship, and here that relationship is the act of editing a Wikipedia article. We see from our network that the “U.S.” and “England” hold central positions in the network, with a mass of editors crowding around them. A perimeter of nations is then held in place by their ties to editors through the U.S. and England, with a second layer of editors and poorly represented nations (Gabon, Laos, Uzbekistan, etc.) around the boundaries of the network.Figure BWe are reminded from this visualisation both of the centrality of the two Western powers even among WP:CSB editoss, and of the peripheral nature of most other nations in the world. But we also learn which editors in the project are contributing most to underrepresented areas, and which are less “tied” to the Western core. Here we see “Wizzy” and “Warofdreams” among the second layer of editors who act as a bridge between the core and the periphery; these are editors with interests in both the Western and marginalised nations. Located along the outer edge, “Gallador” and “Gerrit” have no direct ties to the U.S. or England, concentrating all of their edits on less represented areas of the globe. Identifying editors at these key positions in the network will help with future research, informing interview questions that will investigate their interests further, but more significantly, probing motives for participation and action within the coalition.Additionally, we can break the network down further to discover editors who appear to have similar interests in underrepresented areas. Figure C strips down the network to only editors and edits dealing with Africa and South America, the least represented continents. From this we can easily find three types of editors again: those who have singular interests in particular nations (the outermost layer of editors), those who have interests in a particular region (the second layer moving inward), and those who have interests in both of these underrepresented regions (the center layer in the figure). This last group of editors may prove to be the most crucial to understand, as they are carrying the full load of WP:CSB’s mission.Figure CThe End of Geography, or the Reclamation?In The Internet Galaxy, Manuel Castells writes that “the Internet Age has been hailed as the end of geography,” a bold suggestion, but one that has gained traction over the last 15 years as the excitement for the possibilities offered by information communication technologies has often overshadowed structural barriers to participation like the Digital Divide (207). Castells goes on to amend the “end of geography” thesis by showing how global information flows and regional Internet access rates, while creating a new “map” of the world in many ways, is still closely tied to power structures in the analog world. The Internet Age: “redefines distance but does not cancel geography” (207). The work of WikiProject: Countering Systemic Bias emphasises the importance of place and representation in the information environment that continues to be constructed in the online world. This study looked at only a small portion of this coalition’s efforts (~16,000 edits)—a snapshot of their labor frozen in time—which itself is only a minute portion of the information being dispatched through Wikipedia on a daily basis (~125,000 edits). Further analysis of WP:CSB’s work over time, as well as qualitative research into the identities, interests and motivations of this collective, is needed to understand more fully how information bias is understood and challenged in the Internet galaxy. The data here indicates this is a fight worth fighting for at least a growing few.ReferencesAlexa. “Top Sites.” Alexa.com, n.d. 10 Mar. 2010 ‹http://www.alexa.com/topsites>.

It all started with a tweet. On the afternoon of 2 June 2013, Professor Geoffrey Miller, an evolutionary psychologist at the University of New Mexico (UNM) and visiting instructor at New York University (NYU), tweeted out a message that would go on to generate a significant social media controversy. Addressing aspiring doctoral program applicants, Miller wrote:Dear obese PhD applicants: if you didn’t have the willpower to stop eating carbs, you won't have the willpower to do a dissertation #truthThe response to Miller’s tweet was swift and fiery. Social media users began engaging with him on Twitter, and in the early hours of the controversy Miller defended the tweet. When one critic described his message as “judgmental,” Miller replied that doing a dissertation is “about willpower/conscientiousness, not just smarts” (Trotter). The tweet above, now screen captured, was shared widely and debated by journalists, Fat Acceptance activists, and academic social media users. Within hours Miller had deleted the tweet and replaced it with two new ones:My sincere apologies to all for that idiotic, impulsive, and badly judged tweet. It does not reflect my true views, values, or standards andObviously my previous tweet does not represent the selection policies of any university, or my own selection criteriaHe then made his Twitter account private. The captured image, however, continued to spread. Across social media, users began to circulate a campaign that called for Miller to be formally disciplined (Trotter). There was also widespread talk about potential lawsuits from prospective students who were not selected for admission at UNM (Kirby). Indeed, the Fat Chick Sings blogger Jeanette DePatie offered her own advice to Miller: #findagoodlawyer.Soon after the controversy emerged a response appeared on UNM’s website in the form of a video statement by Professor Jane Ellen Smith, the Chair of the UNM Psychology Department. Smith reiterated that Miller’s statements did not reflect the “policies and admissions standards of UNM”. She also stated that Miller had defended his actions by claiming the tweet was part of a “research project” where he would deliberately send out provocative messages in order to measure the public response to them. This claim was met with incredulity by a number of bloggers and columnists, and was later determined to be incorrect in an Institutional Review Board inquiry at UNM, which concluded Miller’s tweets were “self-promotional” in nature. Following a formal investigation, the UNM committee found no evidence that Miller had discriminated against overweight students. It did however pass a motion of censure that included a number of restrictions, including prohibiting Miller from sitting on any graduate admission committee at UNM.The #truth about Fat PhDs?Readers may be wondering why Miller’s tweet continues to matter as I write this article in 2015. It is my belief that the tweet is important insofar as it affords an insight into the cultural scene that surrounds the fat body in higher education. The vigorous debate generated by Miller’s tweet offers researchers a diverse array of media texts that are available to help build a more comprehensive picture of fat embodiment within higher education.Looking at the tweet in the cold light of day it is difficult to imagine any logical links one might infer between a person’s carbohydrate consumption and their ability to excel in doctoral education. And there’s the rub. Of course Miller’s tweet does not represent a careful evaluation of the properties of doctoral willpower. In order to make sense of the tweet we need to understand the ways cultural assumptions about fatness operate. For decades now, researchers have documented the existence of anti-fat attitudes (Crandall & Martinez). Increasingly, scholars and Fat Acceptance activists have described a “thinness norm” that is reproduced across contemporary Western cultures, which discerns normatively slender bodies as “both healthy and beautiful” (Eller 220) and those whose bodies depart from this norm, as “socially acceptable targets for shaming and hate speech” (Eller 220). In order to be intelligible Miller’s tweet relies on a number of deeply entrenched cultural meanings attributed to fatness and fat people.The first is that body-size is primarily a matter of self-control. Although Critical Fat Studies researchers have argued for some time that body weight is determined by complex interactions between the biological and environmental, the belief that a large body size is caused by limited self-control remains prevalent. This in turn supports a host of cultural connotations, which tend to constitute fat people as “lazy, gluttonous, greedy, immoral, uncontrolled, stupid, ugly and lacking in willpower” (Farrell 4).In light of the above, Miller’s message ought to be read as a moral one. I have paraphrased its logic as such: if you [the fat doctoral student] lack the willpower to discipline your body into normatively desired slimness, you will also likely lack the strength of character required to discipline your body-mind into producing a doctoral dissertation. The sad irony here is that, if anything, the attitudes that might hamper fat students from pursuing a doctoral education would be those espoused in Miller’s own tweet. As Critical Fat Studies researchers have illuminated, the anti-fat attitudes the tweet reproduces generate challenging higher education climates for fat people to navigate (Pausé, Express Yourself 6).Indeed, while Miller’s tweet is one case that arose to media prominence, there is evidence that it sits inside a wider pattern of weight discrimination within higher education. For example, Caning and Mayer (“Obesity: Its Possible”, “Obesity: An Influence”) found that despite similar high school performances, ‘obese’ students were less likely to be accepted to elite universities, than their non-obese peers. In a more recent US-based study, Burmeister and colleagues found evidence of weight bias in graduate school admissions. In particular, they found that higher body mass index (BMI) applicants received fewer post-interview offers into psychology graduate programs than other students (920), and this relationship appeared to be stronger for female applicants (920). This picture is supported by a study by Swami and Monk, who examined weight bias against women in a hypothetical scenario about university acceptance. In this study, 198 volunteers in the UK were asked to identify the women they were most and least likely to select for a place at university. Swami and Monk found that participants were biased against fat women, a finding which the authors interpreted as evidence of broader public beliefs about body size and access to higher education.In my examination of the media scene surrounding the Miller case I observed that most commentators associated the tweet with a particular affective formation – shame. Miller’s actions were widely described as “fat-shaming” (Bennet-Smith; Ingeno; Martin; Trotter; Walsh) with Miller himself often referred to simply as the “fat-shaming professor” (King; ThinkTank). In this article I wish to consider the affective-political dimensions of Miller’s tweet, by focusing on one digital community’s response to it: Fuck Yeah! Fat PhDs. In following this path I am building on the work of other researchers who have considered fat activisms and Web 2.0 (Pausé, Express Yourself); fat visual activism (Gurrieri); and the emotional politics of fat acceptance blogging (Kargbo; Bronstein).Imaging Alternatives: Fuck Yeah! Fat PhDsBy 3 June 2013 – just one day after Miller’s tweet was published – New Zealand-based academic Cat Pausé had created the Tumblr Fuck Yeah! Fat PhDs. This was billed as a photo-blog about “being fatlicious in academia”. Writing on her Friend of Marilyn blog, Pausé explained the rationale behind the Tumblr:I decided that what I wanted to do was to highlight all the amazing fat individuals who are in graduate school, or have completed graduate school – to provide a visual repository … and to celebrate the amazing work being done by these rad fatties!Pausé sent out calls for participants on Twitter, Tumblr and Facebook, and emailed a Fat Studies listserv. She asked submitters to send “a photo, along with their name, degree, and awarding institution” (Pausé Express Yourself, 6). Images were submitted thick and fast. Twenty-three were published in the first day of the project, and twenty in the second. At the time of writing, just over 150 images had been submitted, the most recent being November 2013.The Fuck Yeah! Fat PhDs project ought to be understood as part the turn away from the textual toward the digital in fat activist movements (Kargbo). This has seen a growth in online communities that are interested in developing “counter-images in response to the fat body’s position as the abject, excluded Other of the socially acceptable body” (Kargbo 162). Examples include a multitude of Fatshion photo-blogs, Tumblrs like Exciting Fat People or the Stocky Bodies image library, which responds to the limited diversity of visual representations of fat people in the mainstream media (Gurrieri).For this article, I have read the images on the Fuck Yeah! Fat PhDs Tumblr in order to gain an impression about the affective-political work accomplished by this collective of self-identified fat academic bodies. As I indicated earlier, much of the commentary following Miller’s tweet characterised it as an attempt to ‘shame’ fat doctoral students. As Elspeth Probyn has identified, shame frequently manifests itself on the body “most experiences of shame make you want to disappear, to hide away and to cover yourself” (Probyn 329). I suggest that the core work of the Fuck Yeah! Fat PhDs Tumblr is to address the spectre of shame Miller’s tweet projects with visibility, rather than it’s opposite. This visibility also enables the project to proliferate a host of different ways of (feeling about) being fat and doctoral.The first image posted on the Tumblr is Pausé’s own. She is pictured smiling at the 2007 graduation ceremony where she received her own PhD, surrounded by fellow graduates in academic regalia. Her image is followed by many others, mostly white women, who attest to the academic attainments of fat individuals. My first impression as I scrolled through the Tumblr was to note that many of the images (51) referenced scenes of graduation, where subjects wore robes, caps or posed with higher degree certificates. Many more were the kinds of photographs that one might expect to be taken at an academic event. Together, these images attest to the viability of the living, breathing doctoral body - a particularly relevant response given Miller’s tweet. This work to legitimate the fat doctoral body was also accomplished through the submission of two historical photographs of Albert Einstein, a figure who is neither living nor breathing, but highly unlikely to be described as lacking academic ability or willpower.As I read through the Tumblr subsequent times, I noticed that many of the submitters offered images that challenge stereotypical representations of the fat body. As a number of writers have noted, fat people tend to be visually represented as “solitary, lonely figures whose expressions are downcast and dejected” (Gurrieri 202). That is if they aren’t already decapitated in the visual convention of the “headless fatty” used across news media (Kargbo 160). Like the Stocky Bodies project, the Fuck Yeah! Fat PhDs Tumblr facilitated a more diverse and less pathologising representation of fat (doctoral) embodiment.Across the images there is little evidence of the downcast eyes of shame and dejection that Miller’s tweet seems to invite of aspiring fat doctoral candidates. Scrolling through the Tumblr one encounters images of fat people singing, swimming, creating art, playing sport, smoking, smiling, dressing up, and making music. A number of images (12) emphasise the social nature of fat doctoral life, by picturing multiple subjects at once, some holding hands, others posing with colleagues, loved ones, and a puppy. Another category of submissions took a playful stance vis-à-vis some representational conventions of imaging fatness. Where portrayals of the fat body from side or rear angles, or images of fat people eating and drinking typically code an affective scene of disgust (Gurrieri), a number of images on the Tumblr appear to reinscribe these scenes with new meaning. Viewers are offered pictures of smiling and contented fat graduates unashamed to eat and drink, or be represented from ‘unflattering’ angles.Furthermore, a number of images offered alternatives to the conventional representation of the fat subject as ugly and sexually unattractive by posing in glamorous shots bubbling with allure and desire. In one memorable picture, blogger and educator Virgie Tovar is snapped wearing a “sex instructor” badge and laughs while holding two sex toys.Reading across the images it becomes clear that the Tumblr offers a powerful response to the visual convention of representing the solitary, lonely fat person. Rather than presenting isolated fat doctoral students the act of holding the images together generates a sense of fat higher education community, as Kargbo notes:A single image posted online amidst vast Internet ephemera is just a fleeting document of a moment in a stranger’s life. But in the plural, as one scrolls through hundreds of images eager to hit the ‘next’ button for what will be a repetition of the same, the image takes on a new function: it becomes an insistent testament to the liveness of fat embodiment in the present. (164)Obesity Timebomb blogger Charlotte Cooper (2013) commented on the significance of the project: “It is pretty amazing to see the names and faces as I scroll through Fuck yeah! Fat PhDs. Many of us are friends and collaborators and the site represents a new community of power.”Concluding Thoughts: Fat Embodiment and Higher Education CulturesThis article has examined a cultural event that that saw the figure of the fat doctoral student rise to international media prominence in 2013. I have argued that while Miller’s tweet can be read as illustrative of the affective scene of shame that surrounds the fat body in higher education, the images offered by the Fuck Yeah! photo submitters work to re-negotiate implication in social discourses of abjection. Indeed, the images assert that alternative ways of feeling about being fat and doctoral remain viable. Fat students can be contented, ambivalent, sultry, pissed off, passionate and proud – and Fuck Yeah! Fat PhDs provides submitters with a platform to perform a wide array of these affects. This is not to say that shame is shut out of the project, or the lives of submitters’ altogether. Instead, I am suggesting that the Tumblr generates a more open field of possibilities, providing “a space for re-imagining new forms of attachments and identifications.” (Kargbo 171). Critics might argue that this Tumblr is not particularly novel when set in the context of a range of fat photo-blogs that have sprung up across the Internet in recent years. I would argue, however, that when we consider the kinds of questions Fuck Yeah! Fat PhDs might ask of university cultures, and the prompts it offers to higher education researchers, the Tumblr can be seen to make an important contribution. I am in agreement with Kargbo (2013) when she argues that fat photo-blogs “have the potential to alter the conditions of visual reception and perception”. That is, through their “codes and conventions, styles of lighting and modes of address, photographs literally show us how to relate to another person” (Singer 602). When read together, the Fuck Yeah! images insist that a different kind of relationship to fat PhDs is possible, one that exceeds the shaming visible in Miller’s tweet. Ultimately then, the Tumblr is a call to take fat doctoral students seriously, not as problems in need of fixing, but as a diverse group of scholars who make important contributions to the academy and beyond.I would like to use the occasion of concluding this article to call for further conversations about fat embodiment and higher education cultures. The area is significantly under-researched, with higher education scholars largely failing to engage with the material and affective experiences of fat embodiment. Indeed, I would argue that if nothing else, this paper has demonstrated that public scenes of knowledge creation have done a much more comprehensive job of analysing the intersection of ‘fat + university’ than academic books and articles to date. While not offering an exhaustive sketch, I would like to gesture toward some areas that might contribute to a future research agenda. For example, researchers might begin to approach the experience of living, working and studying as a fat person in the contemporary university. Such research might examine whose body the university is imagined and designed for, as well as the campus climate experienced by fat individuals. Researchers might consider how body size could become a part of broader conversations about embodiment and privilege in higher education, alongside race, ability, gender identity, and other categories of social difference.Thinking about the intersection of ‘fat + university’ would also involve tracing possibilities. For example, what role do university campuses play as spaces of fat activism and solidarity? And, what is the contribution made by Critical Fat Studies as a newly established interdisciplinary field of inquiry?Taken together, I hope the questions I have raised in this article demonstrate that the intersection of ‘fat’ and higher education cultures represents a rich and valuable area that warrants further inquiry.ReferencesBennet-Smith, Meredith. “Geoffrey Miller, Visiting NYU Professor, Slammed for Fat-Shaming Obese PhD Candidates.” 6 Apr. 2013.
