The use of hemin iron byCorynebacterium diphtheriaerequires the DtxR- and iron-regulated ABC hemin transporter HmuTUV and the secreted Hb-binding protein HtaA. We recently described two surface anchored proteins, ChtA and ChtC, which also bind hemin and Hb. ChtA and ChtC share structural similarities to HtaA; however, a function for ChtA and ChtC was not determined. In this study, we identified additional host iron sources that are utilized byC. diphtheriae. We show that severalC. diphtheriaestrains use the hemoglobin-haptoglobin (Hb-Hp) complex as an iron source. We report that anhtaAdeletion mutant ofC. diphtheriaestrain 1737 is unable to use the Hb-Hp complex as an iron source, and we further demonstrate that achtA-chtCdouble mutant is also unable to use Hb-Hp iron. Single-deletion mutants ofchtAorchtCuse Hb-Hp iron in a manner similar to that of the wild type. These findings suggest that both HtaA and either ChtA or ChtC are essential for the use of Hb-Hp iron. Enzyme-linked immunosorbent assay (ELISA) studies show that HtaA binds the Hb-Hp complex, and the substitution of a conserved tyrosine (Y361) for alanine in HtaA results in significantly reduced binding.C. diphtheriaewas also able to use human serum albumin (HSA) and myoglobin (Mb) but not hemopexin as iron sources. These studies identify a biological function for the ChtA and ChtC proteins and demonstrate that the use of the Hb-Hp complex as an iron source byC. diphtheriaerequires multiple iron-regulated surface components.

The causative relationship between specific mitochondrial molecular structure and reactive oxygen species (ROS) generation has attracted much attention. NDUFA13 is a newly identified accessory subunit of mitochondria complex I with a unique molecular structure and a location that is very close to the subunits of complex I of low electrochemical potentials. It has been reported that down-regulated NDUFA13 rendered tumor cells more resistant to apoptosis. Thus, this molecule might provide an ideal opportunity for us to investigate the profile of ROS generation and its role in cell protection against apoptosis. In the present study, we generated cardiac-specific tamoxifen-inducible NDUFA13 knockout mice and demonstrated that cardiac-specific heterozygous knockout (cHet) mice exhibited normal cardiac morphology and function in the basal state but were more resistant to apoptosis when exposed to ischemia-reperfusion (I/R) injury. cHet mice showed a preserved capacity of oxygen consumption rate by complex I and II, which can match the oxygen consumption driven by electron donors ofN,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD)+ascorbate. Interestingly, at basal state, cHet mice exhibited a higher H2O2level in the cytosol, but not in the mitochondria. Importantly, increased H2O2served as a second messenger and led to the STAT3 dimerization and, hence, activation of antiapoptotic signaling, which eventually significantly suppressed the superoxide burst and decreased the infarct size during the I/R process in cHet mice.

In Alzheimer disease (AD) patients, degeneration of the cholinergic system utilizing acetylcholine for memory acquisition is observed. Since AD therapy using acetylcholinesterase (AChE) inhibitors are only palliative for memory deficits without slowing or reversing disease progress, there is a need for effective therapies, and stem cell-based therapeutic approaches targeting AD should fulfill this requirement. We established a human neural stem cell (NSC) line encoding choline acetyltransferase (ChAT) gene, an acetylcholine-synthesizing enzyme. APPswe/PS1dE9 AD model mice transplanted with the F3.ChAT NSCs exhibited improved cognitive function and physical activity. Transplanted F3.ChAT NSCs in the AD mice differentiated into neurons and astrocytes, produced ChAT protein, increased the ACh level, and improved the learning and memory function. F3.ChAT cell transplantation reduced Aβ deposits by recovering microglial function; i.e., the down-regulation of β-secretase and inflammatory cytokines and up-regulation of Aβ-degrading enzyme neprilysin. F3.ChAT cells restored growth factors (GFs) and neurotrophic factors (NFs), and they induced the proliferation of NSCs in the host brain. These findings indicate that NSCs overexpressing ChAT can ameliorate complex cognitive and physical deficits of AD animals by releasing ACh, reducing Aβ deposit, and promoting neuroregeneration by the production of GFs/NFs. It is suggested that NSCs overexpressing ChAT could be a candidate for cell therapy in advanced AD therapy.

A Review of: Meert-Williston, D., & Sandieson, R. (2019). Online Chat Reference: Question Type and the Implication for Staffing in a Large Academic Library. The Reference Librarian, 60(1), 51-61. http://www.tandfonline.com/doi/full/10.1080/02763877.2018.1515688 Abstract Objective – Determine the type of online chat questions to help inform staffing decisions for chat reference service considering their library’s service mandate. Design – Content analysis of consortial online chat questions. Setting – Large academic library in Canada. Subjects – Analysis included 2,734 chat question transcripts. Methods – The authors analyzed chat question transcripts from patrons at the institution for the period of time from September 2013 to August 2014. The authors coded transcripts by question type using a coding tool created by the authors. For transcripts that fit more than one question type, the authors chose the most prominent type. Main Results – The authors coded the chat questions as follows: service (51%), reference (25%), citation (9%), technology (7%), and miscellaneous (8%). The majority of service questions were informational, followed by account related questions. Most of the reference chat questions were ready reference with only 16% (4% of the total number of chat questions) being in-depth. After removing miscellaneous questions, those that required a high level of expertise (in-depth reference, instructional, copyright, or citation) equaled 19%. Conclusion – At this institution, one in five chat questions needed a high level of expertise. Library assistants with sufficient expertise could effectively answer circulation and general reference questions. With training they could triage complex questions.

Cultural-Historical Activity Theory (CHAT) was conceived and has been developed as an interventionist proposal and mostly as an analytical tool. The aim of this paper is to explore the connections between ontological and epistemological considerations underpinning CHAT and concrete research methodological decisions. We discuss how considerations of the philosophical basis of CHAT and more recent developments in philosophy can offer specific guidance to methodological decisions by exploring an example of research about using technology to teach in secondary science education. The explicit definition of the ontological character of activity, the status of the concept of transformation, or considering points of entry as an epistemological device suggest a possible logic to define data-gathering methods which could be generalised to other areas of CHAT research. We also discuss complementary frameworks, in particular the concept of identity, to develop a more comprehensive understanding of the complex and dynamic nature of the activity.

Hypoxic chemosensitivity of peripheral arterial chemoreceptors and the ventilatory response to O2 deprivation increases with postnatal development. Multiple putative neurotransmitters, which are synthesized in the carotid body (CB), are thought to mediate signals generated by hypoxia. Acetylcholine (ACh) is believed to be a major excitatory neurotransmitter participating in hypoxic chemosensitivity. However, it is not known whether ACh originates from type I cells in the CB. In these studies, we tested the hypothesis that choline acetyltransferase (ChAT) and vesicular ACh transporter (VAChT) mRNAs are expressed in the CB and that mRNA levels would increase with postnatal maturation or exposure to hypoxia. Semiquantitative in situ hybridization histochemistry and immunohistochemistry were used to localize cholinergic markers within neurons and cells of the rat CB, the nodose-petrosal-jugular ganglion complex, and the superior cervical ganglion up to postnatal day 28. We show that the pattern of distribution, in tissue sections, is similar for both ACh markers; however, the level of VAChT mRNA is uniformly greater than that of ChAT. VAChT mRNA and immunoreactivity are detected abundantly in the nodose-petrosal-jugular ganglion complex in a number of microganglion cells embedded in nerve fibers innervating the CB for all postnatal groups, whereas ChAT mRNA is detected in only a few of these cells. Contrary to our hypothesis, postnatal maturation caused a reduction in ACh trait expression, whereas hypoxic exposure did not induce the upregulation of VAChT and ChAT mRNA levels in the CB, microganglion, or within the ganglion complex. The present findings indicate that the source of ACh in the CB is likely within autonomic microganglion cells and cholinergic nerve terminals.

Hospital practitioners rely on care partners of older adults to provide complex care without identifying and addressing their needs. The Care Partner Hospital Assessment Tool (CHAT) was developed to identify the education skill training needs of care partners of hospitalized older adults. This two-phased mixed-method study evaluated the appropriateness and feasibility of the CHAT. The phase 1 quantitative survey with caregiving experts indicated 70–100% agreement for the length and helpfulness of the CHAT (n = 23). These results were supported by phase 2 qualitative interviews with hospital administrators and practitioners, which revealed the following themes: (1) intuitive and clear design worth sustaining and (2) concerns and proposed solutions for implementation. Findings suggest the CHAT is an appropriate and feasible tool for hospital practitioners to tailor their education and skills training to address care partners’ needs. Identifying care partners’ needs is an important step in ensuring they are prepared to complete their caregiving responsibilities.

Дисертація на здобуття наукового ступеня доктора технічних наук за спеціальністю 05.02.08 – технологія машинобудування (13 – механічна інженерія). – Національний технічний університет «Харківський політехнічний інститут», Харків, 2019. У дисертаційній роботі проведено комплекс досліджень, спрямованих на вирішення важливої науково-технічної проблеми в області технології машинобудування: розробка інноваційних та короткотривалих технологій поверхневого зміцнення деталей машин порошковими сумішами керованого складу для забезпечення експлуатаційних властивостей виробів на високому рівні при значному зниженні затрат на їх виготовлення. Розроблено загальний методологічний підхід керування технологічними процесами поверхневого зміцнення деталей порошковими сумішами керованого складу при насиченні поверхневих шарів азотом, вуглецем і бором на основі використання інноваційних технологій і системного аналізу при мінімальних витратах, що дозволило підвищити експлуатаційні властивості виробів при значному скороченні тривалості ХТО. Розроблено комплексні ХТО, які значно знижують крихкість борованих шарів за рахунок більш плавного зниження твердості від поверхні до серцевини виробів зі сталей для підвищення експлуатаційних властивостей виробів та терміну служби деталей машин та інструменту. Удосконалено технологію борування з паст титанових сплавів за рахунок використання нанодисперсного насичувального середовища, що дозволило скоротити процес борування у 2-3 рази та скоротити технологічний процес виготовлення деталей за рахунок поєднання двох операцій: борування і гартування титанового сплаву. Інтенсифіковано процеси ХТО методами нагрівання струмами високої частоти та за рахунок попередньої лазерної обробки деталей, що дозволило отримати високі експлуатаційні властивості поверхневих шарів при значному скороченні тривалості обробок.
The thesis for the scientific degree of doctor of technical sciences, specialty 05.02.08 – technology of mechanical engineering (13 – mechanical engineering). – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. In the thesis a set of studies was aimed at solving an important scientific and technical problem in the field of engineering technology: the development of innovative and short-term technologies of machine parts surface hardening with controlled composition powder mixtures to ensure the performance properties of products at a high level with a significant reduction in the cost of their production. Mathematical models and nomograms of existing technologies of steels surface hardening were created to determine the specific conditions of ChTT (temperature and duration) based on a given depth of the diffusion layer or the surface hardness of steels, which significantly affects the efficiency of the strengthening processes. The general methodological approach of management of technological processes of details surface hardening by powder mixes of the controlled structure at saturation of surface layers with nitrogen, carbon and boron on the basis of use of innovative technologies and the system analysis at the minimum expenses was developed that allowed to increase operational properties of products at considerable reduction of ChTT duration. ChTT was designed the complex, which significantly reduces the fragility of boriding layers due to a more gradual decrease in hardness from surface to core products from steels to improve the operational properties of the goods and service life of machine parts and tools. It was created a mathematical model of the temperature distribution in the depth of the diffusion layer to determine the nature of the dependencies and obtain data on the temperature distribution in the depth of the product under different processing conditions. It was improved boriding pastes technology of titanium alloys through the use of nanodispersed environment, thereby reducing the boriding process 2-3 times and to shorten the manufacturing process of components by combining two operations: boriding and titanium alloy hardening. The solutions of boundary value diffusion problems by the boundary element method were proposed, which allowed to create a mathematical model of the distribution of boron concentration over the thickness of the hardened titanium alloy. The processes of heating by high-frequency currents and due to the preliminary laser treatment of parts were intensified, which allowed to obtain high performance properties of the surface layers with a significant reduction in the duration of treatments. A comparative analysis of the influence of existing and developed hardening treatments on the change in the depth of the layer, the surface hardness and wear resistance of the surface layer of steel 38Ch2MoAl was done. It was established that the developed complex hardening treatment based on the process of diffusion saturation with boron can provide wear resistance of the surface layers at a high level with abrasive wear.

La toxoplasmose, dûe au parasite Toxoplasma gondii, est une zoonose dite à cycle complexe car le pathogène fait intervenir plusieurs espèces pour assurer sa transmission. Les félidés sont les hôtes définitifs de T. gondii et, lorsqu’ils sont infectés, peuvent excréter des millions d’oocystes dans l’environnement. L’ensemble des animaux à sang chaud, y compris l’homme, constituent les hôtes intermédiaires. L'infection des différents hôtes s'effectuent par transmission verticale ou via l'ingestion de tissus animaux contaminés ou d'oocystes présents dans l'environnement.Les objectifs de ma thèse étaient i) de mesurer la fréquence et la distribution spatiale des oocystes de T. gondii dans l’environnement en milieu rural, ii) d'estimer la prévalence et la distribution spatiale de l’infection dans la communauté locale de rongeurs, iii) de déterminer les principaux facteurs responsables de la structuration spatiale de la contamination environnementale et enfin, iv) d’évaluer l'importance de l'environnement en tant que source de contamination tant pour les animaux que pour l’homme.Nous avons mis en évidence une forte contamination des sols (29%) distribuée sur l'ensemble de la zone et, avons révélé un gradient spatial similaire de diminution de la contamination avec la distance aux bâtiments au niveau des sols et dans la communauté de rongeurs. Le modèle de simulation multi-agents a permis d'expliciter le rôle prépondérant de la configuration de l'habitat humain, qui de par son effet sur la structuration spatiale des populations de chats domestiques, détermine la fréquence et la distribution des points chauds de contamination. Par conséquent, en milieu rural, l'importante contamination des sols au niveau des fermes suggère que le risque d’infection pour l’homme est élevé, indirectement à travers la consommation de viande issue d’animaux d’élevage infectés, mais aussi directement via l’ingestion d’oocystes présents sur les substrats manipulés lors de diverses activités
Toxoplasmosis, caused by the parasite T. gondii, is a zoonosis with a complex life cycle as the pathogen requires several different species to achieve it cycle. Felids, in particular domestic cats, are the definitive hosts of the parasite and when infected they can shed millions of oocysts in the environment. All warm blooded animals, including humans, are potential intermediate hosts. Host species can be infected through vertical transmission or by ingesting contaminated tissues or oocysts present on environmental substrates.My goals were: I) to precisely measure the frequency and spatial distribution of the environmental contamination to T. gondii in a rural area, ii) to estimate the prevalence and the spatial distribution of the parasite in the local community of rodents, iii) to identify the main factors driving the spatial structure of the environmental contamination and finally, iv) to assess the importance of the environment as a transmission source for animals and humans.First, we found a high frequency of contaminated soil samples (29%) that were largely distributed across the whole area, and, we found a similar spatial gradient of decreasing contamination with increasing distances from buildings for soils and rodents. Altogether, the results obtained allowed to identify and rank the determinants of the spatio-temporal dynamics of the environmental contamination to T. gondii. The agent-based model showed the primary role of the spatial configuration of human habitat, which, through its impact on the spatial structure of domestic cat populations, determines the frequency and distribution of the hot spots of soil contamination. Thus, in rural areas, the high level of contamination within and around agricultural buildings suggests that infection risks for humans are important, either indirectly through the consumption of contaminated meat or directly due to the ingestion of oocysts contaminating earth, water or vegetables

Augmentative and alternative communication (AAC) is an evidence-based practice targeting the communication deficits of children with complex communication needs (CCN). While young children with communication disorders are attending preschool and using AAC, and specifically speech-generating devices (SGDs), with increasing frequency, best practices for implementation with this population are largely unexplored. In an effort to contribute to the knowledge base for teachers, the essential communication partners for children in the classroom setting, this research explored the interactions of four teacher-child dyads and analyzed the prompts and cues used to elicit communicative acts from the children. Results of statistical and descriptive analyses revealed that, while teachers overwhelmingly favor and use verbal prompts over other stimuli, these prompts were no more effective in eliciting communicative acts. These results indicate that teachers would benefit from instruction in a variety of techniques for enhancing communication via AAC; future research directions towards this purpose are detailed.

Ce travail a porté sur l'étude de la dynamique de la transmission d'un parasite à cycle complexe, Toxoplasma gondii, dans des milieux contrastés. Dans une première partie, la dynamique de la transmission du parasite est étudiée dans un site urbain abritant une population très dense de chats domestiques (Felis catus). Nos travaux permettent de poser l'hypothèse d'un cycle de transmission parasitaire simple lorsque les hôtes intermédiaires sont en densité très faible relativement à celle des chats. Par ailleurs, nous mettons en évidence l'existence de zones de contamination du sol par les oocystes de T. gondii, qui sont très localisées, et qui correspondent aux zones de défécation communes des chats. Dans une deuxième partie, la variabilité de la dynamique de transmission de T. gondii dans les milieux riches en hôtes intermédiaires est abordée. Nous mettons notamment en évidence des indicateurs de la variabilité interspécifique du niveau d'infection chez les hôtes intermédiaires (masse corporelle spécifique et habitat). Par ailleurs, nous montrons qu'il existe des relations entre la composition de l'environnement, la variabilité du climat, et le niveau d'infection de la toxoplasmose chez le chat domestique et le chat forestier (Felis silvestris). L'ensemble du travail montre l'intérêt d'une approche éco-épidémiologique dans la compréhension de la variabilité du cycle de T. gondii, notamment par l'utilisation du suivi à long terme de plusieurs populations de chats vivant dans différents environnements. Il ouvre la voie à différentes perspectives de recherche, tant sur le plan appliqué (amélioration de la détection d'oocystes) que sur un aspect de modélisation.

The neural code from the inner ear to the brain is dynamically controlled by central nervous efferent feedback to the audio-vestibular epithelium. Although such efference provides the basis for a cognitive control of our hearing and balance, we know surprisingly little about this feedback system. This project has investigated the applicability of a transgenic mouse model, expressing a fluorescent protein under the choline-acetyltransferase (ChAT) promoter, for targeting the cholinergic audio-vestibular efferent neurons in the brainstem. It was found that the mouse model is useful for targeting the vestibular efferents, which are fluorescent, but not the auditory efferents, which are not highlighted. This model enables, for the first time, physiological studies of the vestibular efferent neurons and their synaptic inputs. We next assessed the expression of the potassium channel family Kv4, known to generate transient potassium currents upon depolarization. Such potassium currents are found in auditory efferent neurons, but it is not known whether Kv4 subunits are expressed in these neurons. Moreover, it is not known if Kv4 is present and has a function in the vestibular efferent neurons. Double labelling with anti-ChAT and anti-Kv4.2 or Kv4.3 demonstrates that the Kv4.3 subunits are abundantly expressed in audio-vestibular efferents, thus indicating that this subunit is a large contributor to the excitability and firing properties of the auditory efferent neurons, and most probably also for the vestibular efferent neurons. In addition, we also unexpectedly found a strong expression of Kv4.3 in principal cells of the superior olive, the neurons which are important for sound localization.

This diploma thesis describes how to create or convert traditional Java programs to desktop-like rich internet applications with the Google Web Toolkit. The Google Web Toolkit is an open source development environment, which translates Java code to browser and device independent HTML and JavaScript. Most of the GWT framework parts, including the Java to JavaScript compiler as well as important security issues of websites will be introduced. The famous Agricola board game will be implemented in the Model-View-Presenter pattern to show that complex user interfaces can be created with the Google Web Toolkit. The Google Web Toolkit framework will be compared with the JavaServer Faces one to find out which toolkit is the right one for the next web project
Diese Diplomarbeit beschreibt die Erzeugung desktopähnlicher Anwendungen mit dem Google Web Toolkit und die Umwandlung klassischer Java-Programme in diese. Das Google Web Toolkit ist eine Open-Source-Entwicklungsumgebung, die Java-Code in browserunabhängiges als auch in geräteübergreifendes HTML und JavaScript übersetzt. Vorgestellt wird der Großteil des GWT Frameworks inklusive des Java zu JavaScript-Compilers sowie wichtige Sicherheitsaspekte von Internetseiten. Um zu zeigen, dass auch komplizierte graphische Oberflächen mit dem Google Web Toolkit erzeugt werden können, wird das bekannte Brettspiel Agricola mittels Model-View-Presenter Designmuster implementiert. Zur Ermittlung der richtigen Technologie für das nächste Webprojekt findet ein Vergleich zwischen dem Google Web Toolkit und JavaServer Faces statt

Technology doesn't flow smoothly; it's the big surprises that matter, and Yale computer expert David Gelernter sees one such giant leap right on the horizon. Today's small scale software programs are about to be joined by vast public software works that will revolutionize computing and transform society as a whole. One such vast program is the "Mirror world." Imagine looking at your computer screen and seeing reality--an image of your city, for instance, complete with moving traffic patterns, or a picture that sketches the state of an entire far-flung corporation at this second. These representations are called Mirror worlds, and according to Gelernter they will soon be available to everyone. Mirror worlds are high-tech voodoo dolls: by interacting with the images, you interact with reality. Indeed, Mirror worlds will revolutionize the use of computers, transforming them from (mere) handy tools to crystal balls which will allow us to see the world more vividly and see into it more deeply. Reality will be replaced gradually, piece-by-piece, by a software imitation; we will live inside the imitation; and the surprising thing is--this will be a great humanistic advance. we gain control over our world, plus a huge new measure of insight and vision. In this fascinating book--part speculation, part explanation--Gelernter takes us on a tour of the computer technology of the near future. Mirror worlds, he contends, will allow us to explore the world in unprecedented depth and detail without ever changing out of our pajamas. A hospital administrator might wander through an entire medical complex via a desktop computer. Any citizen might explore the performance of the local schools, chat electronically with teachers and other Mirror world visitors, plant software agents to report back on interesting topics; decide to run for the local school board, hire a campaign manager, and conduct the better part of the campaign itself--all by interacting with the Mirror world. Gelernter doesn't just speculate about how this amazing new software will be used--he shows us how it will be made, explaining carefully and in detail how to build a Mirror world using technology already available. we learn about "disembodied machines," "trellises," "ensembles," and other computer components which sound obscure, but which Gelernter explains using familiar metaphors and terms. (He tells us that a Mirror world is a microcosm just like a Japanese garden or a Gothic cathedral, and that a computer program is translated by the computer in the same way a symphony is translated by a violinist into music.) Mirror worlds offers a lucid and humanistic account of the coming software revolution, told by a computer scientist at the cutting edge of his field.

In this chapter, how the complex technology of Second Life affects participation in an English course is investigated. With the aim of exploring gender issues, the special affordance of Second Life, i.e. voice-morphing together with sound-isolated parcels, was used. The data set consists of about 33 hours of audio recordings and chat logs of 8,315 words. The results show that in audio10.8% of the course time deals with technological challenges, while in chat 69.2% of the words contribute to technology. Three challenges interfering with participation were identified: software complexity, unreliable functionality of Second Life, and hardware and connectivity issues. To deal with these problems, pedagogical facilitators, technological facilitators, and Second Life -experienced peers made a significant contribution. Based on the results, this chapter analyzes whether Second Life can be widely used in language education, how affordances of it can be learned and taught, and scenarios where Second Life can and cannot be used.

This essay centers around two queer British men who came to New York to perform the story of their lives in a confessional mode: Quentin Crisp in 1979 with his show An Evening with Quentin Crisp, and Bette Bourne in 2010 with his performance A Life in Three Acts. Both shows posed as evenings of plain, immediate chat, but both, in fact, were complex, remediated things. This essay argues that such complex media schemes are, in fact, a crucial characteristic of confessional monologue, which has pervaded American theater since the 1980s.

This chapter focuses on Google Wave, a new, emerging world-wide technology by Google that supports both synchronous and asynchronous communication. Research on this technology took place during two sessions of an advanced second language (L2) technology course whereby synchronous conversations in Google Wave were compared to synchronous conversations in Blackboard chat rooms. Students experienced both forms of technology while discussing cross-cultural and pedagogical discussions relevant to L2 learning. Structural comparisons in terms of message length, message turns, numbers of words, and clarification revealed that students were more patient and wrote lengthier, more complex posts when conversing in Google Wave as compared to the chat room. Students’ impressions further confirmed their awareness of writing and reflecting more within Google Wave. These results suggest that Google Wave will support flexible, innovative learning and will provide researchers with multiple opportunities for expanding our understanding of students’ interactions in synchronous environments.

I complete this study in this final chapter by turning to conversations with working-class and middle-class men I first met online through social media and chat sites during my six years of fieldwork. Subsequently, I conducted over 50 hour-long, semi-structured, face-to-face interviews with these self-identified homosexual men of Maghrebi and Maghrebi French origin. I draw on conversation and critical discourse analysis in this chapter to show how their stories of challenge and resilience often resonate with those analyzed in the previous chapters.

As the Internet has been adopted and integrated in the daily lives of an increasing number of young adolescents in western countries, scholars and commentators are debating and speculating on the impact of these new media on the activities, social relationships and worldview of the young generation. The communication environment has become more and more complex, as youth combine the use of electronic mail, open forums, chat rooms, instant messenger and social networking sites. In this chapter the author argues that the use of different social applications, partially define the structure and content of social communication and association. In this chapter the author reviews the literature on the motivations for the use of each social application and the impact of the use on the type, size and quality of social ties that are maintained and created.

We focus on the people and asks what role does personal choice and interaction play? The key issue here is the role of face-to-face interaction in the transfer of complex, uncertain knowledge. It analyses the different sorts of knowledge and relationships involved in day-to-day exchanges. This leads on to the milieux for such exchange, from meetings to bar-chat to the digital world; and to the need (or not) for frequent access to each other, and thus to the communication networks: digital in all cases, physical to varying degrees in others. This need varies according to the differential importance of knowledge, confidence and judgement across sectors and firms. All of it is more or less amenable to replacement by ICT; the questions explored are: what is the core of irreplaceable contact, to whom does it still matter and, consequently, what are the locational effects for cities and their hinterlands?

Predicting anomalies (e.g., blocked driveway and vehicle collisions) in urban space plays an important role in assisting governments and communities for building smart city applications, ranging from intelligent transportation to public safety. However, predicting urban anomalies is not trivial due to the following two factors: i) The sequential transition regularities of anomaly occurrences is complex, which exhibit with high-order and dynamic correlations. ii) The Interactions between region, time and anomaly category is multi-dimensional in real-world urban anomaly forecasting scenario. How to fuse multiple relations from spatial, temporal and categorical dimensions in the predictive framework remains a significant challenge. To address these two challenges, we propose a Cross-Interaction Hierarchical Attention network model (CHAT) which uncovers the dynamic occurrence patterns of time-stamped urban anomaly data. Our CHAT framework could automatically capture the relevance of past anomaly occurrences across different time steps, and discriminates which types of cross-modal interactions are more important for making future predictions. Experiment results demonstrate the superiority of CHAT framework over state-of-the-art baselines.

Despite the valuable information contained in software chat messages, disentangling them into distinct conversations is an essential prerequisite for any in-depth analyses that utilize this information. To provide a better understanding of the current state-of-the-art, we evaluate five popular dialog disentanglement approaches on software-related chat. We find that existing approaches do not perform well on disentangling software-related dialogs that discuss technical and complex topics. Further investigation on how well the existing disentanglement measures reflect human satisfaction shows that existing measures cannot correctly indicate human satisfaction on disentanglement results. Therefore, in this paper, we introduce and evaluate a novel measure, named DLD. Using results of human satisfaction, we further summarize four most frequently appeared bad disentanglement cases on software-related chat to insight future improvements. These cases include (i) Ignoring Interaction Patterns, (ii) Ignoring Contextual Information, (iii) Mixing up Topics, and (iv) Ignoring User Relationships. We believe that our findings provide valuable insights on the effectiveness of existing dialog disentanglement approaches and these findings would promote a better application of dialog disentanglement in software engineering.

The Southeast Coast Network (SECN) Wadeable Stream Habitat Monitoring Protocol collects data to give park resource managers insight into the status of and trends in stream and near-channel habitat conditions (McDonald et al. 2018a). Wadeable stream monitoring is currently implemented at the five SECN inland parks with wadeable streams. These parks include Horseshoe Bend National Military Park (HOBE), Kennesaw Mountain National Battlefield Park (KEMO), Ocmulgee Mounds National Historical Park (OCMU), Chattahoochee River National Recreation Area (CHAT), and Congaree National Park (CONG). Streams at Congaree National Park chosen for monitoring were specifically targeted for management interest (e.g., upstream development and land use change, visitor use of streams as canoe trails, and potential social walking trail erosion) or to provide a context for similar-sized stream(s) within the park or network (McDonald and Starkey 2018a). The objectives of the SECN wadeable stream habitat monitoring protocol are to: Determine status of upstream watershed characteristics (basin morphology) and trends in land cover that may affect stream habitat, Determine the status of and trends in benthic and near-channel habitat in selected wadeable stream reaches (e.g., bed sediment, geomorphic channel units, and large woody debris), Determine the status of and trends in cross-sectional morphology, longitudinal gradient, and sinuosity of selected wadeable stream reaches. Between June 11 and 14, 2018, data were collected at Congaree National Park to characterize the in-stream and near-channel habitat within stream reaches on Cedar Creek (CONG001, CONG002, and CONG003) and McKenzie Creek (CONG004). These data, along with the analysis of remotely sensed geographic information system (GIS) data, are presented in this report to describe and compare the watershed-, reach-, and transect-scale characteristics of these four stream reaches to each other and to selected similar-sized stream reaches at Ocmulgee Mounds National Historical Park, Kennesaw Mountain National Battlefield Park, and Chattahoochee National Recreation Area. Surveyed stream reaches at Congaree NP were compared to those previously surveyed in other parks in order to provide regional context and aid in interpretation of results. edar Creek’s watershed (CONG001, CONG002, and CONG003) drains nearly 200 square kilometers (77.22 square miles [mi2]) of the Congaree River Valley Terrace complex and upper Coastal Plain to the north of the park (Shelley 2007a, 2007b). Cedar Creek’s watershed has low slope and is covered mainly by forests and grasslands. Cedar Creek is designated an “Outstanding Resource Water” by the state of South Carolina (S.C. Code Regs. 61–68 [2014] and S.C. Code Regs. 61–69 [2012]) from the boundary of the park downstream to Wise Lake. Cedar Creek ‘upstream’ (CONG001) is located just downstream (south) of the park’s Bannister Bridge canoe landing, which is located off Old Bluff Road and south of the confluence with Meyers Creek. Cedar Creek ‘middle’ and Cedar Creek ‘downstream’ (CONG002 and CONG003, respectively) are located downstream of Cedar Creek ‘upstream’ where Cedar Creek flows into the relatively flat backswamp of the Congaree River flood plain. Based on the geomorphic and land cover characteristics of the watershed, monitored reaches on Cedar Creek are likely to flood often and drain slowly. Flooding is more likely at Cedar Creek ‘middle’ and Cedar Creek ‘downstream’ than at Cedar Creek ‘upstream.’ This is due to the higher (relative to CONG001) connectivity between the channels of the lower reaches and their out-of-channel areas. Based on bed sediment characteristics, the heterogeneity of geomorphic channel units (GCUs) within each reach, and the abundance of large woody debris (LWD), in-stream habitat within each of the surveyed reaches on Cedar Creek (CONG001–003) was classified as ‘fair to good.’ Although, there is extensive evidence of animal activity...
