At its most fundamental, entrepreneurship involves discovering, evaluating, and exploiting opportunities to create future goods and services (Shane and Venkataraman, 2000). Acknowledging that characteristics, emotions, cognitive biases, and past experiences influence entrepreneurial activity and decision making (Shepherd and Patzelt, 2017; De Winnaar and Scholtz, 2019), many propose that active reflection is an important facet of the entrepreneurial curricula (Nabi et al., 2016; Santos et al., 2016). For the entrepreneurial student, learning to make rationale decisions is paramount, and this is vitally linked to their ability to reflect and be self-aware.
This study recounts the use of the eportfolio within a new large class (over 600 students) module in enterprise education. The module utilised an eportfolio reflective assignment to allow students express their feelings and knowledge about a series of attended entrepreneurial events and guest speaker seminars. In this paper, we present a novel insight into the efficacy of this curricular approach. External stakeholders who acted as mentors and speakers were asked to review a number of these student portfolios, and provide their thoughts on the assignments themselves, and the e-portfolio construct more generally. As such, this study highlights the multiple feedback loops of reflection which can be obtained from the eportfolio when used as a carefully considered pedagogical tool. It also highlights the integral role that industry stakeholders play in the enterprise curriculum.

Launched in 2013, Vine is a popular microblogging service that allows users to record, edit, and share six-second videos that loop ad libitum, until another video is selected. At this time, the communicative, expressive, and semiotic affordances of Vine and similar services have still to be fully explored by users and scholars alike. Through a multimodal analysis approach drawing on New London Group’s (1996) work, this paper investigates how people construct humour on Vine by artfully arranging different modes of expression. The analysis focused on user-enacted humour, as opposed to captured comical scenes or bare samples taken from TV shows or movies. The study hypothesises the social construction of a novel humorous language that draws on extant forms of humour and a variety of modes and techniques derived from audio-visual media and computer-mediated communication, as users inventively exploit the framework provided by the Vine platform. Findings show that users create instant characters to amplify the impact of their solo video recordings, use Vine as a “humorous confessional”, explore the potential of hand-held media by relying on “one hand and face” expressivity (the other hand holding the device for the video “selfie”), and use technology, internet slang, internet acronyms, emoticons/emojis, and hashtags to convey humour and complement the messages of the videos they post on Vine. The goal of this study is an exploratory analysis of humour and its discursive functions in an emergent social medium by considering its affordances, as users find new and creative ways to harness its expressive potential.

Abstract This paper examines aspects of strategic interaction and the construction of the social actor in a neo-Austinian framework of illocutionary acts. The basic premise of the neo-Austinian framework is conventionality, according to which illocutionary acts depend on social agreement. An important part of the framework is the felicity condition of entitlement, directly related to the hearer’s understanding of the conventions that should hold for an act performance. Two strategies of challenging and/or rejecting illocutionary acts are then identified tentatively dubbed looping and backfiring, related to the hearer’s perception of when the entitlement felicity condition is flouted. Both strategies can be overtly or covertly confrontational and demonstrate that in their social quality illocutionary acts serve to construct the social actor and build up interpersonal relations.

Abstract: This paper analyzes a clock using Arduino without Real time clock (RTC). The development of the digital clock in Arduino is to provide its own time without RTC. Generally, electronic circuit designers use RTC to construct a clock. Such a circuit requires an extra circuit and power. The CMOS battery supplies power to the RTC, once the CMOS battery power is discharged. It automatically erases the date and time and requires an update from an external device. Considering these facts, RTC is avoided and code with nested looping is used to maintain timing in Arduino. It enables us to modify the time using a keypad and LCD without an external device. Continuous power is supplied to the Arduino using a battery backup. Such a circuit is simple with reduced code. All features available in RTC are available in this circuit. Keywords: Arduino Atmega 328P, RTC, LCD16 x 2, Keypad 4x3.

Abstract Abstract 1469 Poster Board I-492 The LIM domain binding protein LDB1 is an essential cofactor of LIM-homeodomain (LIM-HD) and LIM-only (LMO) proteins in hematopoiesis and other developmental programs. We have shown that LDB1 and its LIM-HD and LMO interaction partners are protected from ubiquitylation by a small family of SSBPs. Recently, we demonstrated that these SSBPs bind to LDB1 homodimers to promote formation of a ternary complex containing two molecules of LDB1 and SSBP. This was dependent on an intact LDB1 dimerization domain (DD) and produced a shift, directly or indirectly, in the equilibrium between LDB1 monomer and dimer. In the present study, we introduced a 24-glycine linker between two full-length LDB1 peptide-coding sequences and expressed this forced or tethered LDB1 dimer (TD-LDB1) in vitro and in vivo. First, both TD-LDB1, introduced into cells by transfection, and endogenous LDB1 were found to have the same turnover rate, indicating that protection from ubiquitylation was independent of dimerization status. Second, TD-LDB1 was fused to the DNA binding domain of GAL4 (GAL4DBD) and in a second construct to the activation domain of herpesvirus VP16 (VP16AD) and these constructs were expressed in cells with a GAL4 reporter plasmid. Co-expression of GAL4-LDB1 and VP16-LDB1 significantly increased reporter luciferase activity as a result of dimerization, while co-expression of GAL4-TD-LDB1 with VP16-LDB1 did not, ruling out formation of LDB1 trimers. Likewise, co-expression of GAL4-TD-LDB1 with VP16-TD-LDB1 did not significantly affect luciferase activity, indicating that LDB1 also cannot form protein tetramers. In contrast, TD-LDB1 was able to bind SSBP2 and SSBP3 in both chemical cross-linking and mammalian two-hybrid assays, consistent with the SSBP interacting with preformed LDB1 dimers. Finally, the complete 200-amino acid DD of LDB1, reported as necessary and sufficient for protein dimerization, was confirmed in cross-linking analysis to act as a dominant negative inhibitor of LDB1 dimerization. When the DD was introduced into Lhx2-, Ldb1-, and Ssbp3-expressing cells, application of a modified electrophoretic mobility assay that can detect linking of two DNA probes in solution revealed that the DD reduced formation of a ‘looped’ complex containing two DNA probes and led to the appearance of a new complex containing Lhx2, Ssbp3, and Ldb1, apparently in a monomeric form. In summary, this work elucidates a novel function of SSBPs in enhancing LDB1 dimerization and, ultimately, long-range communication between cis regulatory regions in genes. In addition, it suggests that SSBPs bind dimeric LDB1 and induce an allosteric change in the adjacent SSBP interaction domain rather than vice versa. Finally, these results lead to the prediction that an SSBP- and LDB1-containing complex could promote looping between promoter-proximal and promoter-distal LIM-HD binding elements.

Chronos versus Thanatos in a post-apocalyptic world as presented in Tatyana Tolstaya’s The Slynx and Oleh Shynkarenko’s KaharlykThe article explores issues related to images and concepts used by the writers of dystopias imagining a post-apocalyptic world to diagnose the condition of their national communities. The author discusses, among other things, the means of presenting time such as metaphors of looping or stopping time, which help construct the messages conveyed in the novels. Particular attention is paid to the contrast between Chronos and Thanatos — figures representing time and death, which are widely used in culture. In the analyzed novels, this contrast, which is characteristic of post-Enlightenment secular consciousness, is reflected in the creation of an antithesis between the historic and the archaic.

Protein–DNA loops are essential for efficient transcriptional repression and activation. The geometry and stability of the archetypal Lac repressor tetramer (LacI)–DNA loop were investigated using designed hyperstable loops containing lac operators bracketing a sequence-directed bend. Electrophoretic mobility shift assays, DNA cyclization, and bulk and single-molecule fluorescence resonance energy transfer (FRET) demonstrate that the DNA sequence controls whether the LacI–DNA loop forms a compact loop with positive writhe or an open loop with little writhe. Monte Carlo methods for simulation of DNA ring closure were extended to DNA loops, including treatment of variable protein hinge angles. The observed distribution of topoisomer products upon cyclization provides a strong constraint on possible models. The experiments and modeling imply that LacI–DNA can adopt a wide range of geometries but has a strong intrinsic preference for an open form. The flexibility of LacI helps explain in vivo observations that DNA looping is less sensitive to DNA length and shape than that expected from the physical properties of DNA. While DNA cyclization suggests two pools of precursor loops for the 9C14 construct, single-molecule FRET demonstrates a single population. This discrepancy suggests that the LacI–DNA structure is strongly influenced by flanking DNA.

Abstract Ewing sarcoma is an aggressive bone-associated tumor currently treated with dose-intense chemotherapy, radiation, and surgery. Ewing sarcoma affects adolescents and young adults with incidence rate of 3 per million. The hallmark of Ewing sarcoma is a translocated fusion transcription factor named EWS FLI that drives the oncogenic process. The lack of efficient and targeted treatment in Ewing sarcoma directly arises from the poor understanding of how EWS/FLI regulates expression of thousands of genes as well as the current lack of effective targeting of transcription factors. We hypothesize that FLI portion of EWS::FLI containing a crucial alpha-helix plays a novel role in transcription regulation of thousands of genes by modulating chromatin looping. We postulated this hypothesis based on recent evidence from our lab that established an alpha-helix immediately downstream of DNA binding domain as an important player in regulating transcriptional activity in A673 cell line. Structure-function mapping revealed that ETS domain alone was insufficient for full transcriptional regulation. The purpose of this study is to elucidate the mechanism underlying transcriptional regulation by FLI and it is likely to guide future studies on novel therapeutics for Ewing sarcoma patients as transcriptional factors remain elusive targets of therapy. We utilized knockdown/rescue experiments in which EWS FLI was depleted with shRNA and replaced with constructs containing the ETS DNA Binding Domain (DBD) alone or DBD+ (ETS DNA Binding Domain and 4th alpha-helix). The knockdown/rescue experiments were confirmed at mRNA level using qPCR, and at protein level using immunoblots. The binding pattern and transcriptional regulation of DBD and DBD+ were assessed with RNA-Seq respectively. The extent of roles each of these construct play in organization, structure, and function of chromatin are being assessed using Micro-C technique, a variation of Hi-C with improved resolution, higher signal-to-noise ratio and more information on chromatin domain boundaries and chromatin looping. The DNA binding and genomic localization of EWS FLI was unaltered by the deletion surrounding the DNA binding domain (which contains a 4th alpha-helix) in A673 cells. Despite this similarity in genomic localization and binding, the transcriptional output driven by EWS FLI was significantly diminished by the deletion. In addition, we observed this differential transcriptional output by the EWS FLI DBD and DBD+ in another Ewing sarcoma cell line called TTC466. Current work in our lab shows that EWS FLI has a substantial role in shaping the chromatin landscape of Ewing sarcoma cells. We observed this result with Hi-C technique upon the depleting EWS FLI from A673 cells. With this current study, we hope to understand if the flanking region neighboring the DNA binding domain contributes to the chromatin architecture remodeling function of EWS FLI and whether this function could be attributed to the transcriptional output differences in the DBD and DBD+ conditions.

Establishment of left-right (L-R) asymmetry is fundamental to vertebrate development. Several genes involved in L-R asymmetry have been described. In the Xenopus embryo, Vg1/activin signals are implicated upstream of asymmetric nodal related 1 (Xnr1) and Pitx2 expression in L-R patterning. We report here that Zic3 carries the left-sided signal from the initial activin-like signal to determinative factors such as Pitx2. Overexpression of Zic3 on the right side of the embryo altered the orientation of heart and gut looping, concomitant with disturbed laterality of expression of Xnr1 and Pitx2, both of which are normally expressed in the left lateral plate mesoderm. The results indicate that Zic3 participates in the left-sided signaling upstream of Xnr1 and Pitx2. At early gastrula, Zic3 was expressed not only in presumptive neuroectoderm but also in mesoderm. Correspondingly, overexpression of Zic3 was effective in the L-R specification at the early gastrula stage, as revealed by a hormone-inducible Zic3 construct. The Zic3 expression in the mesoderm is induced by activin (beta) or Vg1, which are also involved in the left-sided signal in L-R specification. These findings suggest that an activin-like signal is a potent upstream activator of Zic3 that establishes the L-R axis. Furthermore, overexpression of the zinc-finger domain of Zic3 on the right side is sufficient to disturb the L-R axis, while overexpression of the N-terminal domain on the left side affects the laterality. These results suggest that Zic3 has at least two functionally important domains that play different roles and provide a molecular basis for human heterotaxy, which is an L-R pattern anomaly caused by a mutation in human ZIC3.

Il software conserva la maggior parte del know-how che occorre per svilupparlo. Poiché oggigiorno il software può essere facilmente duplicato e ridistribuito ovunque, il rischio che la proprietà intellettuale venga violata su scala globale è elevato. Una delle più interessanti soluzioni a questo problema è dotare il software di un watermark. Ai watermark si richiede non solo di certificare in modo univoco il proprietario del software, ma anche di essere resistenti e pervasivi. In questa tesi riformuliamo i concetti di robustezza e pervasività a partire dalla semantica delle tracce. Evidenziamo i cicli quali costrutti di programmazione pervasivi e introduciamo le trasformazioni di ciclo come mattone di costruzione per schemi di watermarking pervasivo. Passiamo in rassegna alcune fra tali trasformazioni, studiando i loro principi di base. Infine, sfruttiamo tali principi per costruire una tecnica di watermarking pervasivo. La robustezza rimane una difficile, quanto affascinante, questione ancora da risolvere.Software retains most of the know-how required fot its development. Because nowadays software can be easily cloned and spread worldwide, the risk of intellectual property infringement on a global scale is high. One of the most viable solutions to this problem is to endow software with a watermark. Good watermarks are required not only to state unambiguously the owner of software, but also to be resilient and pervasive. In this thesis we base resiliency and pervasiveness on trace semantics. We point out loops as pervasive programming constructs and we introduce loop transformations as the basic block of pervasive watermarking schemes. We survey several loop transformations, outlining their underlying principles. Then we exploit these principles to build some pervasive watermarking techniques. Resiliency still remains a big and challenging open issue.

Unfortunately, many programmers hesitate to use series expressions, because they are typically implemented very inefficiently---the prime source of inefficiency being the creation of intermediate series objects. A restricted class of series expressions, obviously synchronizable series expressions, is defined which can be evaluated very efficiently. At the cost of introducing restrictions which place modest limits on the series expressions which can be written, the restrictions guarantee that the creation of intermediate series objects is never necessary. This makes it possible to automatically convert obviously synchronizable series expressions into highly efficient loops using straight forward algorithms.

The words we use both reflect and shape societal attitudes and inflect the interactions of physicians and patients. Words construct concepts of causality and assign responsibility for illness, often attributing blame to patients. This chapter describes how patients are considered “poor historians” who arrive with “chief complaints” and are “non-compliant” with prescribed medications. It emphasizes the need for physicians to be aware of how their words and demeanors affect their patients and how infantilizing language is detrimental to the well-being of the dependent elderly. It explores the impact of apparently innocent word choices, how medical students learn that talking with patients is considered unimportant, and how words shape our thoughts and how we see the world. The chapter examines how labeling and classifying people may lead to “making up people,” creating ways of being made possible by the new taxonomy and explores this “looping effect” in the instance of “cancer survivors.”

This paper describes an extension of a novel, carbon-burning, fluid phase chemical looping combustion system proposed previously. The system generates both power and H2 with ‘inherent’ carbon capture using chemical looping combustion (CLC) to perform the main energy release from the fuel. A mixed Pb and Zn based oxygen carrier is used, and due to the thermodynamics of the carbothermic reduction of PbO and ZnO respectively, the system generates a flue gas which consists of a mixture of CO2 and CO. By product H2 is generated from this flue gas using the water-gas shift reaction (WGSR). By varying the proportion of Pb to Zn circulating in the chemical loop, the ratio of CO2 to CO can be controlled, which in turn enables the ratio between the amount of H2 produced to the amount of power generated to be adjusted. By this means, the power output from the system can be ‘turned down’ in periods of low electricity demand without requiring plant shutdown. To facilitate the adjustment of the Pb/Zn ratio, use is made of the two metal’s mutual insolubility, as this means they form in to two liquid layers at the base of the reduction reactor. The amount of Pb and Zn rich liquid drawn from the two layers and subsequently circulated around the system is controlled thereby varying the Pb/Zn ratio. To drive the endothermic reduction of ZnO formed in the oxidiser, hot Zn vapour is ‘blown’ into the reducer where it condenses, releasing latent heat. The Zn vapour to produce this ‘blast’ of hot gas is generated in a flash vessel fed with hot liquid metal extracted from the oxidiser. A mass and energy balance has been conducted for a power system, operating on the Pb/Zn cycle. In the analysis, reactions are assumed to reach equilibrium and losses associated with turbomachinery are considered; however, pressure losses in equipment and pipework are assumed to be negligible. The analysis reveals that a power system with a second law efficiency of between 62% and 68% can be constructed with a peak turbine inlet temperature of only ca. 1850 K. The efficiency varies as the ratio between power and H2 production varies, with the lower efficiency occurring at the maximum power output condition.
