Social Processes and Technology in an Online Community of Practices

What is the role of technology in an on-line community of practices ? How is the technology used and perceived in the construction of a community ? In this paper we will try to answer these questions by means of the study of a self-help community. We choose a community that has no off-line counterpart – in fact the topic of the community is a mental health care problem known as social anxiety disorder (or social phobia). A person affected by social phobia has great difficulty in attending ordinary social events, but the participation in the on-line community is not seen as a problem by the members. This very peculiar kind of on-line community allows us to study interaction mediated only by technological tools, such as a web site, a forum, a chat. We describe in the paper the various dimensions of the practices in use within the community, focusing in particular on the learning process undergone by new members when they enter the community.
The kinematics of the planetary nebula BD+30°3639

In this paper we describe the results of the first optical kinematic study of the planetary nebula BD+30°3639. This system has a central star of the Wolf–Rayet type and is believed to be fairly young. Emission-line spectra were obtained at high spectral and spatial resolution using the Utrecht echelle spectrometer at the William Herschel Telescope. These spectra indicate that the main ionized shell of BD+30°3639 appears to be evolving in a more complex way than previously thought.
Perception and Wayfinding at Cultural Sites

Projects in historical and cultural heritage have achieved major relevance in recent years. The importance of these sites is based on their intrinsic value and the visitation options to communicate knowledge to everyone, regardless of their abilities. Wayfinding plays an important role in achieving this goal to make cultural heritage accessible. However, the achievement of accessibility for everyone in these projects is not easy. This requires a sensitive perception of people in their various situations and an exercise of restraint to balance the past and present, memory and invention. It is not possible to develop a single objective and universally valid theory. Each case must be studied to provide useful and respectful solutions. New technology applications offer a wide range of opportunities which vary from the perceptive experiences that can be produced to the specific nature of future devices and signage systems that can be used to interact with people. This paper will study several information and signage projects in patrimonial and cultural landscapes that use different resources to make the site more accessible. The variety of visual, tactile and acoustic elements coexists with digital resources to highlight the different spaces. This diversity of stimuli can comprise an efficient and dense network of continuously superimposed tools, signs and symbols, which provide the place with a voice and make it more inclusive.
Flexible Use of Phonological and Visual Memory in Language-mediated Visual Search

In language-mediated visual search, memory and attentional resources must be allocated to simultaneously process verbal instructions while navigating a visual scene to locate linguistically specified targets. We investigate when and how listeners use object names in visual-search strategies across three visual world experiments, varying the presence and location of an added visual memory demand. The results suggest that as long as objects in the display can be visually inspected throughout the trial, participants do not linguistically encode those objects. We suggest that instead they use the visual environment as an external memory, mapping the spoken word onto potential referents and using perceptual visual routines automatically triggered by the spoken word. The results are discussed in terms of flexible and efficient allocation of memory resources in natural tasks that combine language and vision.
Emotion enhances remembrance of neutral events past

Emotional events are bestowed with special prominence in memory. This may reflect greater attention oriented to these events during encoding, and/or enhancement of memory consolidation after emotional events have passed. Here we show invoked emotional arousal results in a retrograde enhancement of long-term memory, determining what will later be remembered or forgotten. Subjects saw pictures of neutral faces and houses followed by emotionally arousing scenes at varying intervals. Self-reported emotional arousal responses predicted a retrograde enhancement of memory for preceding neutral events in a 1-week delayed recognition memory test. At longer picture-scene intervals, no enhancement was found, implicating a critical window in which emotional arousal must occur for retrograde memory enhancement. Postencoding manipulation of emotional arousal specifically enhanced conscious recollection rather than familiarity-based discrimination. An additional study revealed no retrograde enhancement for pictures preceding highly memorable, but nonarousing, distinctive scenes. These findings indicate an important role for emotional arousal in the postencoding enhancement of episodic memory consolidation.
Histamine and gut mucosal immune regulation

Histamine is a biogenic amine with extensive effects on many cell types, mediated by the activation of its four receptors (H1R–H4R). Distinct effects are dependent on receptor subtypes and their differential expression. Within the gastrointestinal tract, histamine is present at relatively high concentrations, particularly during inflammatory responses. In this review, we discuss the immunoregulatory influence of histamine on a number of gastrointestinal disorders, including food allergy, scombroid food poisoning, histamine intolerance, irritable bowel syndrome, and inflammatory bowel disease. It is clear that the effects of histamine on mucosal immune homeostasis are dependent on expression and activity of the four currently known histamine receptors; however, the relative protective or pathogenic effects of histamine on inflammatory processes within the gut are still poorly defined and require further investigation.
Stressful Dieting: Nutritional Conditions but Not Compensatory Growth Elevate Corticosterone Levels in Zebra Finch Nestlings and Fledglings

Unfavourable conditions throughout the period of parental care can severely affect growth, reproductive performance, and survival. Yet, individuals may be affected differently, depending on the developmental period during which constraints are experienced. Here we tested whether the nestling phase compared to the fledgling phase is more susceptible to nutritional stress by considering biometry, physiology, sexually selected male ornaments and survival using zebra finches (Taeniopygia guttata) as a model species. As nestlings (day 0–17) or fledglings (day 17–35), subjects were raised either on low or high quality food. A low quality diet resulted in significantly elevated baseline corticosterone titres in both nestlings and fledglings. Subjects showed substantial compensatory growth after they had experienced low quality food as nestlings but catch-up growth did neither lead to elevated baseline corticosterone titres nor did we detect long term effects on biometry, male cheek patch, or survival. The compensation for temporally unfavourable environmental conditions reflects substantial phenotypic plasticity and the results show that costs of catch-up growth were not mediated via corticosterone as a physiological correlate of allostatic load. These findings provide new insights into the mechanisms and plasticity with which animals respond to periods of constraints during development as they may occur in a mistiming of breeding.
“Chotikatwa”, a new culture-bound dissociative syndrome from Northern India: a case series-based report

The author proposes a new culture-bound syndrome, proposed to be named “Chotikatwa”. The syndrome’s genesis is based on frequent occurrence of tail lock of hairs of female patients getting cut under mysterious circumstances. Such cases are being reported from different North Indian states. The description of four cases is being presented in the report. The occurrences have occurred only with females under settings of stress and comorbid cluster B traits are not uncommon. The aetiology of the phenomenon is unknown and various theories, including act of evil, organised gang, and insects cutting hairs, etc. are being discussed in electronic, print, and social media. The phenomenon has not been discussed in academic literature yet as per the knowledge of the author. The report goes into the details of four casestheir investigation, treatment, and details of the phenomenology. A discussion regarding the possible psychological underpinnings has followed in the report.
Rapid Molecular Detection Methods for Arboviruses of Livestock of Importance to Northern Europe

Arthropod-borne viruses (arboviruses) have been responsible for some of the most explosive epidemics of emerging infectious diseases over the past decade. Their impact on both human and livestock populations has been dramatic. The early detection either through surveillance or diagnosis of virus will be a critical feature in responding and resolving the emergence of such epidemics in the future. Although some of the most important emerging arboviruses are human pathogens, this paper aims to highlight those diseases that primarily affect livestock, although many are zoonotic and some occasionally cause human mortality. This paper also highlights the molecular detection methods specific to each virus and identifies those emerging diseases for which a rapid detection methods are not yet developed.
Interactive Recommender Systems: Tutorial

In this tutorial we will explore the field of interactive video and music recommendations and their application at Netflix and Spotify. Interactive recommender systems enable the user to steer the received recommendations in the desired direction through explicit interaction with the system. In this tutorial, we outline the various aspects that are crucial for a smooth and effective user experience. In particular, we present our insights from several A/B tests. The tutorial will help researchers and practitioners in the RecSys community to gain a deeper understanding of the challenges related to the application of recommender systems in the online video and music entertainment business.
Concurrent compaction using a field pinning protocol

Compaction of memory in long running systems has always been important. The latency of compaction increases in today’s systems with high memory demands and large heaps. To deal with this problem, we present a lock-free protocol allowing for copying concurrent with the application running, which reduces the latencies of compaction radically. It provides theoretical progress guarantees for copying and application threads without making it practically infeasible, with performance overheads of 15% on average. The algorithm paves the way for a future lock-free Garbage Collector.
Reflective practice and learning from mistakes in social work student placement

ABSTRACT Student placement is a fundamental component of social work education and an important space where to build critically self-reflective practitioners. Students learn from their reflection on their experience and their mistakes are a powerful opportunity to go behind the surface of events and understand the essence of the profession. This article will present some results from the analysis carried out on the reflective writing of a group of social work students who describe and reflect on the most significant mistakes they made in their field practice using a reflective framework developed for errors and failures. The main results of this experience are illustrated with special focus on the impact and on the emotions, the relationships with service users and the assessment of the cases. Students are often so concentrated on looking at their responsibility that they become almost blind to the systems and interactions that contribute to the negative outcomes of their actions. Social work education programs should emphasize the importance of structured reflective habits and promote the culture of responsibility instead of the ‘blame culture’, that is probably the strongest obstacle to learning from mistakes and preventing their repetition in the future.
Copepods encounter rates from a model of escape jump behaviour in turbulence

A key ecological parameter for planktonic copepod studies is their encounter rates within the same population as well as with other species. The encounter rate is partly determined by copepod's swimming behaviour and is strongly influenced by turbulence of the surrounding environment. A distinctive feature of copepods' motility is their ability to perform quick displacements, often termed jumps, by means of powerful swimming strokes. Such a reaction has been associated to an escape behaviour from flow disturbances due to predators or other external signals. In the present study, we investigate the encounter rates of copepods of the same species in a developed turbulent flow with intensities comparable to those encountered in their natural habitat. This is done by means of a Lagrangian copepod (LC) model that mimics the jump escape reaction behaviour from localized high-deformation rate fluctuations in the turbulent flows. Our analysis shows that the encounter rate for copepods of typical perception radius of ∼, where is the dissipative scale of turbulence, can be increased by a factor up to ∼102 compared to that experienced by passively transported fluid tracers of the same size. Furthermore, we address the effect of a minimal waiting time between consecutive jumps. It is shown that any encounter-rate enhancement is lost if such time goes beyond the dissipative time-scale of turbulence, Because typically in the ocean ∼1mm and, ∼1s, this provides stringent constraints on the turbulent-driven enhancement of contact-rate due to a purely mechanical induced escape reaction. The implications of our results in the context of copepod ecology copepods are discussed.
Affinity Density: a novel genomic approach to the identification of transcription factor regulatory targets

Methods: A new method was developed for identifying novel transcription factor regulatory targets based on calculating Local Affinity Density. Techniques from the signal-processing field were used, in particular the Hann digital filter, to calculate the relative binding affinity of different regions based on previously published in vitro binding data. To illustrate this approach, the complete genomes of Drosophila melanogaster and D.pseudoobscura were analyzed for binding sites of the homeodomain proteinc Tinman, an essential heart development gene in both Drosophila and Mouse. The significant binding regions were identified relative to genomic background and assigned to putative target genes. Valid candidates common to both species of Drosophila were selected as a test of conservation. Results: The new method was more sensitive than cluster searches for conserved binding motifs with respect to positive identification of known Tinman targets. Our Local Affinity Density method also identified a significantly greater proportion of Tinman-coexpressed genes than equivalent, optimized cluster searching. In addition, this new method predicted a significantly greater than expected number of genes with previously published RNAi phenotypes in the heart. Availability: Algorithms were implemented in Python, LISP, R and maxima, using MySQL to access locally mirrored sequence data from Ensembl (D.melanogaster release 4.3) and flybase (D.pseudoobscura).

Dynamic hybrid active reliable multicast (DHARM)

IP multicast plays a very important role in group communication. At the network level IP multicast provides an efficient one-to-many IP packets delivery but without providing any reliability guarantees. Desirable features of reliable multicast include low end-to-end delay, high throughput and scalability. Active networks open a new perspective in providing more efficient solutions to the problems of reliability. However, the existing active reliable multicast protocols are based on receiver-initiated approach for loss recovery. In this paper we propose a new active reliable multicast protocol by combining sender- initiated and receiver-initiated approaches for loss recovery. This approach helps to solve the scalability problems like acknowledgement implosion, recovery load balancing etc.
Economie néo-institutionnelle et développement - une analyse synthétique

La theorie neo-institutionnelle est importante pour le developpement parce que les couts de transaction eleves et l'inefficacite du systeme des droits de propriete constituent les faiblesses capitales des pays en voie de developpement. Grâce a son avantage methodologique dans le traitement des micro-macro et macro-micro transitions, cette theorie est capable d'analyser comment et par quels mecanismes le comportement des individus est soumis a la structure institutionnelle et comment la structure institutionnelle evolue avec les changements de conditions economiques. Grâce a son approche micro-economique, elle reussit a expliquer l'emergence et l'evolution des «micro-institutions», ce qui s'affranchit des limites du paradigme Etat-marche et montre que l'utilisation des micro-institutions se revele plus efficace dans beaucoup de domaines qu'une simple liberalisation ou etatisation au niveau macro. Cette theorie nous permet aussi de porter un nouveau regard sur la rationalite des paysans, la persistance des institutions traditionnelles, et le dynamisme des pays d'Asie du Sud-Est.

Literature Review on Time Series Indexing

Similarity search in time-series databases has become an active research area in the past decade due to the tremendous growth of the amount of temporal data collected and publicly available. The complexity of this similarity problem lies in the high dimensionality of the temporal data making convenient methods inappropriate. The most promising approaches involve dimensionality reduction and indexing techniques which are the subject of this review. After starting with a general introduction to the time-series and classical time-series analyses, we will discuss in detail time-series normalization techniques and relevant distance metrics. We conclude with a review of the dimensionality-reduction and indexing methods proposed to date.

A new approach to MET data extraction is formulated and validated using trajectory simulation data. The projectile dynamics and measurement model are presented. In addition to presenting experimental results of the new MET data extraction methodology and aim-setting optimization for both spin-stabilized and fin-stabilized projectiles, the real-time MET implementation for actual fire control systems based on a componentized decision aid system architecture is also discussed.
Boosting statistical application identification by flow correlation

In this paper, we propose a new online method for traffic classification that combines the statistical and host-based approaches in order to construct a robust and precise method for early Internet traffic identification. We use the packet size as the main feature for the classification and we benefit from the traffic profile of the host (i.e., which application and how much) to decide in favor of this or that application. This profile is updated online based on the result of the classification of previous flows originated by or addressed to the same host. We evaluate our method on real traces using several applications. The results show that leveraging the traffic pattern of the host ameliorates the performance of statistical methods. They also prove the capacity of our solution to derive profiles for the traffic of Internet hosts and to identify the services they provide.
Aspergillus Enzymes Involved in Degradation of Plant Cell Wall Polysaccharides

SUMMARY Degradation of plant cell wall polysaccharides is of major importance in the food and feed, beverage, textile, and paper and pulp industries, as well as in several other industrial production processes. Enzymatic degradation of these polymers has received attention for many years and is becoming a more and more attractive alternative to chemical and mechanical processes. Over the past 15 years, much progress has been made in elucidating the structural characteristics of these polysaccharides and in characterizing the enzymes involved in their degradation and the genes of biotechnologically relevant microorganisms encoding these enzymes. The members of the fungal genus Aspergillus are commonly used for the production of polysaccharide-degrading enzymes. This genus produces a wide spectrum of cell wall-degrading enzymes, allowing not only complete degradation of the polysaccharides but also tailored modifications by using specific enzymes purified from these fungi. This review summarizes our current knowledge of the cell wall polysaccharide-degrading enzymes from aspergilli and the genes by which they are encoded.
Approximate controllability of stochastic PDE with infinite delays driven by Possion jumps

The weak approximate controllability of stochastic partial differential equations (PDEs) with infinite delays and Possion jumps is discussed. According to the fixed-point theorem of Krasnoselski-Schaefer and assumption of the approximate controllability for its corresponding linear system, the existence of the mild solution to stochastic PDEs is established. The sufficient conditions for the weak approximate controllability of stochastic PDEs are also obtained.
