  12. Context in a wider context

    Directory of Open Access Journals (Sweden)

    John Traxler

    2011-07-01

    Full Text Available This paper attempts to review and reconsider the role of context in mobile learning and starts by outlining definitions of context-aware mobile learning as the technologies have become more mature, more robust and more widely available and as the notion of context has become progressively richer. The future role of context-aware mobile learning is considered within the context of the future of mobile learning as it moves from the challenges and opportunities of pedagogy and technology to the challenges and opportunities of policy, scale, sustainability, equity and engagement with augmented reality, «blended learning», «learner devices», «user-generated contexts» and the «internet of things». This is essentially a perspective on mobile learning, and other forms of technology-enhanced learning (TEL, where educators and their institutions set the agenda and manage change. There are, however, other perspectives on context. The increasing availability and use of smart-phones and other personal mobile devices with similar powerful functionality means that the experience of context for many people, in the form of personalized or location-based services, is an increasingly social and informal experience, rather than a specialist or educational experience. This is part of the transformative impact of mobility and connectedness on our societies brought about by these universal, ubiquitous and pervasive technologies. This paper contributes a revised understanding of context in the wider context (sic of the transformations taking place in our societies. These are subtle but pervasive transformations of jobs, work and the economy, of our sense of time, space and place, of knowing and learning, and of community and identity. This leads to a radical reconsideration of context as the notions of ‹self› and ‹other› are transformed.

  14. Generative Contexts

    Science.gov (United States)

    Lyles, Dan Allen

    Educational research has identified how science, technology, engineering, and mathematics (STEM) practice and education have underperforming metrics in racial and gender diversity, despite decades of intervention. These disparities are part of the construction of a culture of science that is alienating to these populations. Recent studies in a social science framework described as "Generative Justice" have suggested that the context of social and scientific practice might be modified to bring about more just and equitable relations among the disenfranchised by circulating the value they and their non-human allies create back to them in unalienated forms. What is not known are the underlying principles of social and material space that makes a system more or less generative. I employ an autoethnographic method at four sites: a high school science class; a farm committed to "Black and Brown liberation"; a summer program geared towards youth environmental mapping; and a summer workshop for Harlem middle school students. My findings suggest that by identifying instances where material affinity, participatory voice, and creative solidarity are mutually reinforcing, it is possible to create educational contexts that generate unalienated value, and circulate it back to the producers themselves. This cycle of generation may help explain how to create systems of justice that strengthen and grow themselves through successive iterations. The problem of lack of diversity in STEM may be addressed not merely by recruiting the best and the brightest from underrepresented populations, but by changing the context of STEM education to provide tools for its own systematic restructuring.

  5. Contexts as Shared Commitments

    Directory of Open Access Journals (Sweden)

    Manuel eGarcía-Carpintero

    2015-12-01

    Full Text Available Contemporary semantics assumes two different notions of context: one coming from Kaplan (1989, on which contexts are sets of predetermined parameters, and another originated in Stalnaker (1978, on which contexts are sets of propositions that are common ground. The latter is deservedly more popular, given its flexibility to account for context-dependent aspects of language beyond manifest indexicals, such as epistemic modals, predicates of taste, and so on and so forth; in fact, properly dealing with demonstratives (perhaps ultimately all indexicals requires that further flexibility. Even if we acknowledge Lewis (1980 point that, in a sense, Kaplanian contexts already include common ground contexts, it is better to be clear and explicit about what contexts constitutively are. Now, Stalnaker (1978, 2002, 2014 defines context-as-common-ground as a set of propositions, but recent work shows that this is not an accurate conception. The paper explains why, and provides an alternative. The main reason is that several phenomena (presuppositional treatments of pejoratives and predicates of taste, forces other than assertion require that the common ground includes non-doxastic attitudes such as appraisals, emotions, etc. Hence the common ground should not be taken to include merely contents (propositions, but those together with attitudes concerning them: shared commitments, as I will defend.

    Full Text Available This squib studies the order in which elements are added to the shared context of interlocutors in a conversation. It focuses on context updates within one hierarchical structure and argues that structurally higher elements are entered into the context before lower elements, even if the structurally higher elements are pronounced after the lower elements. The crucial data are drawn from a comparison of relative clauses in two head-initial languages, English and Icelandic, and two head-final languages, Korean and Japanese. The findings have consequences for any theory of a dynamic semantics.

  12. METRIC context unit architecture

    Energy Technology Data Exchange (ETDEWEB)

    Simpson, R.O.

    1988-01-01

    METRIC is an architecture for a simple but powerful Reduced Instruction Set Computer (RISC). Its speed comes from the simultaneous processing of several instruction streams, with instructions from the various streams being dispatched into METRIC's execution pipeline as they become available for execution. The pipeline is thus kept full, with a mix of instructions for several contexts in execution at the same time. True parallel programming is supported within a single execution unit, the METRIC Context Unit. METRIC's architecture provides for expansion through the addition of multiple Context Units and of specialized Functional Units. The architecture thus spans a range of size and performance from a single-chip microcomputer up through large and powerful multiprocessors. This research concentrates on the specification of the METRIC Context Unit at the architectural level. Performance tradeoffs made during METRIC's design are discussed, and projections of METRIC's performance are made based on simulation studies.

  14. Theorising context in psychology

    Glaveanu, Vlad Petre

    2014-01-01

    This article aims to address the issue of what context is and how it can be incorporated in psychological theory by using the case study of creativity research. It starts from a basic definition of context as the spatiotemporal continuum that, together with psychological phenomena, constitutes...... a totality and should be considered a single, integrated whole. As such, contexts are neither subjective, existing only in perception, nor are they a set of variables external to the person, but participate directly in the processes under study in psychology. We can therefore distinguish between “flat......” theorising, one-dimensional and overconcerned with intra-psychological factors, and “3-D” models trying to articulate the psychological, the spatial (sociomaterial), and the temporal. These categories are illustrated by different theoretical approaches to creativity. It is argued here that a cultural...

  15. Decisions in poverty contexts.

    Science.gov (United States)

    Shafir, Eldar

    2017-12-01

    The circumstances surrounding poverty-tight financial challenges, instability of income and expenses, low savings, no insurance, and several other stressors-translate into persistent and cognitively taxing hardship for people in poverty contexts. Thoughts about money and expenses loom large, shape mental associations, interfere with other experiences, and are difficult to suppress. The persistent juggling of insufficient resources affects attention, cognitive resources, and ensuing decisions. Despite the demanding struggle with challenging circumstances, people in poverty encounter disdain rather than admiration, and obstacles rather than support. Societal appreciation for the power of context, along with behaviorally informed programs designed to facilitate life under poverty, are essential for those in poverty contexts to be able to make the most of their challenging circumstances.

  17. Context-dependent Generalization

    Directory of Open Access Journals (Sweden)

    Jordan A Taylor

    2013-05-01

    Full Text Available The pattern of generalization following motor learning can provide a probe on the neural mechanisms underlying learning. For example, the breadth of generalization to untrained regions of space after visuomotor adaptation to targets in a restricted region of space has been attributed to the directional tuning properties of neurons in the motor system. Building on this idea, the effect of different types of perturbations on generalization (e.g., rotation versus visual translation have been attributed to the selection of differentially tuned populations. Overlooked in this discussion is consideration of how the context of the training environment may constrain generalization. Here, we explore the role of context by having participants learn a visuomotor rotation or a translational shift in two different contexts, one in which the array of targets were presented in a circular arrangement and the other in which they were presented in a rectilinear arrangement. The perturbation and environments were either consistent (e.g., rotation with circular arrangement or inconsistent (e.g., rotation with rectilinear arrangement. The pattern of generalization across the workspace was much more dependent on the context of the environment than on the perturbation, with broad generalization for the rectilinear arrangement for both types of perturbations. Moreover, the generalization pattern for this context was evident, even when the perturbation was introduced in a gradual manner, precluding the use of an explicit strategy. We describe how current models of generalization might be modified to incorporate these results, building on the idea that context provides a strong bias for how the motor system infers the nature of the visuomotor perturbation and, in turn, how this information influences the pattern of generalization.

  18. Learning in context

    DEFF Research Database (Denmark)

    Keiding, Tina Bering

    2007-01-01

    This article offers a re-description of the concept of learning context. Drawing on Niklas Luhmann and Gregory Bateson it suggests an alternative to situated, social learning and activity theory. The conclusion is that learning context designates an individual's reconstruction of the environment...... through contingent handling of differences and that the individual emerge as learning through the actual construction. Selection of differences is influenced by the learner's actual knowledge, the nature of the environment and the current horizon of meaning in which the current adaptive perspective...... becomes a significant factor. The re-description contributes to didaktik  through renewed understandings of participants' background in teaching and learning....

    When learning their first language, children develop strategies for assigning semantic roles to sentence structures, depending on morphosyntactic cues such as case and word order. Traditionally, comprehension experiments have presented transitive clauses in isolation, and crosslinguistically...... preschoolers. However, object-first clauses may be context-sensitive structures, which are infelicitous in isolation.

    The interactions between cancer cells and their micro- and macroenvironment create a context that promotes tumor growth and protects it from immune attack. The functional association of cancer cells with their surrounding tissues forms a new 'organ' that changes as malignancy progresses. Investigation of this process might provide new insights into the mechanisms of tumorigenesis and could also lead to new therapeutic targets. Under normal conditions, ORGANS are made up of TISSUES that exchange information with other cell types via cell-cell contact, cytokines and the EXTRACELLULAR MATRIX (ECM). The ECM, which is produced by collaboration between STROMAL fibroblasts and EPITHELIAL cells, provides structural scaffolding for cells, as well as contextual information. The endothelial vasculature provides nutrients and oxygen, and cells of the immune system combat pathogens and remove apoptotic cells. Epithelial cells associate into intact, polarized sheets. These tissues communicate through a complex network of interactions: physically, through direct contact or through the intervening ECM, and biochemically, through both soluble and insoluble signalling molecules. In combination, these interactions provide the information that is necessary to maintain cellular differentiation and to create complex tissue structures. Occasionally, the intercellular signals that define the normal context become disrupted. Alterations in epithelial tissues can lead to movement of epithelial sheets and proliferation - for example, after activation of mesenchymal fibroblasts due to wounding.Normally, these conditions are temporary and reversible, but when inflammation is sustained, an escalating feedback loop ensues.Under persistent inflammatory conditions, continual upregulation of enzymes such as matrix metalloproteinases (MMPs) by stromal fibroblasts can disrupt the ECM, and invading immune cells can overproduce factors that promote abnormal proliferation.

    Hnilica, Karel

    2017-07-01

    Full Text Available In the study we tested some hypotheses concerning the influence of a context on stereotypes. Our first hypothesis concerns explicit stereotypes. According to it Czech respondents will ascribe to their own category more positive attributes if a list of categories will include only Czech and Roma people than when it will include also some categories which are more positively evaluated than Czechs. The next hypothesis concerns implicit stereotypes. According to it when using IAT (Implicit Association Test; Greenwald et al., 1998, where there are compared two categories, we will ascertain a more profound difference between attitudes to Czech and Roma people than when we use BFP (Bona Fide Pipeline; Fazio et al., 1995, in which there is no such a comparison. Our next two hypotheses concern consensual stereotypes. According to one of them the content of a consensual stereotype will overlap with content of a no personal stereotype. According to the other, the valences of consensual stereotypes will be more polarized than the mean valences of personal stereotypes. The context will have similar influences on consensual and personal stereotypes. In our two researches there took part two samples (N1 = 86, N2 = 201 of adult members. To ascertain the content of explicit stereotypes we used an open-form technique. The first sample adduced attributes of members of two categories, the second sample adduced attributes of members of twelve categories. We define the consensual stereotype as a set of ten most often cited attributes. To measure implicit stereotypes, we used IAT and BFP. Results show that responses of the respondents were influenced by context in the directions expected. The content of no personal stereotype overlapped with the content of any consensual stereotype. The context had influence on both explicit and implicit measures. At the same time it was found that context had on personal and consensual stereotypes similar, but not identical

    2009-01-01

    This volume contains the proceedings of the Conference Protostellar Jets in Context held by the JETSET Marie Curie Research Training Network in July 2008. This meeting not only served to showcase some of the network's achievements but was also a platform to hear from, discuss and debate the recent findings of world-class astrophysicists in the field of protostellar jet research. Jets from young stars are of course not an isolated astrophysical phenomenon. It is known that objects as diverse as young brown dwarfs, planetary nebulae, symbiotic stars, micro-quasars, AGN, and gamma-ray bursters produce jets. Thus in a series of talks, protostellar jets were put in context by comparing them with their often much larger brethren and also by considering the ubiquitous accretion disks that seem to be necessary for their formation. With this spectrum of contributions on observations and the theory of astrophysical jets and accretion disks, this book serves as a comprehensive reference work for researchers and students...

  3. Mindfulness in cultural context.

    Kirmayer, Laurence J

    2015-08-01

    Mindfulness meditation and other techniques drawn from Buddhism have increasingly been integrated into forms of psychotherapeutic intervention. In much of this work, mindfulness is understood as a mode of awareness that is present-centered and nonevaluative. This form of awareness is assumed to have intrinsic value in promoting positive mental health and adaptation by interrupting discursive thoughts that give rise to suffering. However, in the societies where it originated, mindfulness meditation is part of a larger system of Buddhist belief and practice with strong ethical and moral dimensions. Extracting techniques like mindfulness meditation from the social contexts in which they originate may change the nature and effects of the practice. The papers in this issue of Transcultural Psychiatry explore the implications of a cultural and contextual view of mindfulness for continued dialogue between Buddhist thought and psychiatry. This introductory essay considers the meanings of mindfulness meditation in cultural context and the uses of mindfulness as a therapeutic intervention in contemporary psychiatry and psychology. © The Author(s) 2015.

    Smith, Steven M; Manzano, Isabel

    2010-02-01

    In two experiments, we used an effective new method for experimentally manipulating local and global contexts to examine context-dependent recall. The method included video-recorded scenes of real environments, with target words superimposed over the scenes. In Experiment 1, we used a within-subjects manipulation of video contexts and compared the effects of reinstatement of a global context (15 words per context) with effects of less overloaded context cues (1 and 3 words per context) on recall. The size of the reinstatement effects in Experiment 1 show how potently video contexts can cue recall. A strong effect of cue overload was also found; reinstatement effects were smaller, but still quite robust, in the 15 words per context condition. The powerful reinstatement effect was replicated for local contexts in Experiment 2, which included a no-contexts-reinstated group, a control condition used to determine whether reinstatement of half of the cues caused biased output interference for uncued targets. The video context method is a potent way to investigate context-dependent memory.

    Full Text Available This paper discusses the hermeneutic power of a celebrity (seen from the concept of event, seeking to understand what it reveals about the contemporary context. Based on this premise, we attempt to recognize some aspects of contemporary social life that emerge from the trajectory of a specific celebrity: the former soccer player Ronaldo Fenômeno. This analysis brings to light the hermeneutic power of Ronaldo, i.e., how his life story reveals characteristics of contemporary social life. Individualism, machismo, emphasis on a heteronormative ideal, shifts in the construction of romantic relationships, and the overlapping spheres of public and private life, are some important aspects of contemporary society revealed by this analysis.

  8. Context effects in games

    Directory of Open Access Journals (Sweden)

    Ivo Vlaev

    2007-12-01

    Full Text Available We report an experiment exploring sequential context effects on strategy choices in one-shot Prisoner's Dilemma (PD game. Rapoport and Chammah (1965 have shown that some PDs are cooperative and lead to high cooperation rate, whereas others are uncooperative. Participants played very cooperative and very uncooperative games, against anonymous partners. The order in which these games were played affected their cooperation rate by producing perceptual contrast, which appeared only between the trials, but not between two separate sequences of games. These findings suggest that people may not have stable perceptions of absolute cooperativeness. Instead, they judge the cooperativeness of each fresh game only in relation to the previous game. The observed effects suggest that the principles underlying judgments about highly abstract magnitudes such as cooperativeness may be similar to principles governing the perception of sensory magnitudes.

    2011-01-01

    Smartphones are sensor-rich and Internet-enabled. With their on-board sensors, web services, social media, and external biosensors, smartphones can provide contextual information about the device, user, and environment, thereby enabling the creation of rich, biologically driven applications. We introduce ContextProvider, a framework that offers a unified, query-able interface to contextual data on the device. Unlike other context-based frameworks, ContextProvider offers interactive user feedback, self-adaptive sensor polling, and minimal reliance on third-party infrastructure. ContextProvider also allows for rapid development of new context and bio-aware applications. Evaluation of ContextProvider shows the incorporation of an additional monitoring sensor into the framework with fewer than 100 lines of Java code. With adaptive sensor monitoring, power consumption per sensor can be reduced down to 1% overhead. Finally, through the use of context, accuracy of data interpretation can be improved by up to 80%.

For this, it is argued that there are researches belonging to arts, fundamental researches that compromise the certainty of the assumptions where the sense system of a context has its bases (epoch, culture, nation, region. These researches come ahead of the researches of the rational-discursive enunciation fields, given that the last ones haven’t passed any protocol accepted yet by any community. To bring into play the certainty is done by a cognitive movement named by Martin Heidegger unconcealment [Unverborgenheit], and it consist on the interruption of the habituality of the beings who form the (trustworthy family setting to put into perspective the fundamental structures that allow to produce its sense.

    When students learn algebra for the first time, inevitably they are experiencing transition from arithmetic to algebraic thinking. Once students could apprehend this essential mathematical knowledge, they are cultivating their ability in solving daily life problems by applying algebra. However, as we dig into this transitional stage, we identified possible students' learning obstacles to be dealt with seriously in order to forestall subsequent hindrance in studying more advance algebra. We come to realize this recurring problem as we undertook the processes of re-personalization and re-contextualization in which we scrutinize the very basic questions: 1) what is variable, linear equation with one variable and their relationship with the arithmetic-algebraic thinking? 2) Why student should learn such concepts? 3) How to teach those concepts to students? By positioning ourselves as a seventh grade student, we address the possibility of children to think arithmetically when confronted with the problems of linear equation with one variable. To help them thinking algebraically, Bruner's modes of representation developed contextually from concrete to abstract were delivered to enhance their interpretation toward the idea of variables. Hence, from the outset we designed the context for student to think symbolically initiated by exploring various symbols that could be contextualized in order to bridge student traversing the arithmetic-algebraic fruitfully.

    In developing its recommendations on performance assessment for disposal of low-level radioactive waste, Scientific committee 87-3 of the National Council on Radiation Protection and Measurements (NCRP) has considered a number of topics that provide a context for the development of suitable approaches to performance assessment. This paper summarizes the Committee' discussions on these topics, including (1) the definition of low-level waste and its sources and properties, as they affect the variety of wastes that must be considered, (2) fundamental objectives and principles of radioactive waste disposal and their application to low-level waste, (3) current performance objectives for low-level waste disposal in the US, with particular emphasis on such unresolved issues of importance to performance assessment as the time frame for compliance, requirements for protection of groundwater and surface water, inclusion of doses from radon, demonstrating compliance with fixed performance objectives using highly uncertain model projections, and application of the principle that releases to the environment should be maintained as low as reasonably achievable (ALARA), (4) the role of active and passive institutional controls over disposal sites, (5) the role of the inadvertent human intruder in low-level waste disposal, (6) model validation and confidence in model outcomes, and (7) the concept of reasonable assurance of compliance

  13. The Dark Side of Context: Context Reinstatement Can Distort Memory.

    Science.gov (United States)

    Doss, Manoj K; Picart, Jamila K; Gallo, David A

    2018-04-01

    It is widely assumed that context reinstatement benefits memory, but our experiments revealed that context reinstatement can systematically distort memory. Participants viewed pictures of objects superimposed over scenes, and we later tested their ability to differentiate these old objects from similar new objects. Context reinstatement was manipulated by presenting objects on the reinstated or switched scene at test. Not only did context reinstatement increase correct recognition of old objects, but it also consistently increased incorrect recognition of similar objects as old ones. This false recognition effect was robust, as it was found in several experiments, occurred after both immediate and delayed testing, and persisted with high confidence even after participants were warned to avoid the distorting effects of context. To explain this memory illusion, we propose that context reinstatement increases the likelihood of confusing conceptual and perceptual information, potentially in medial temporal brain regions that integrate this information.

    2014-02-01

    This study investigated whether participants prefer contexts with relatively little cognitive conflict and whether this preference is related to context-specific control. A conflict selection task was administered in which participants had to choose between two categories that contained different levels of conflict. One category was associated with 80% congruent Stroop trials and 20% incongruent Stroop trials, while the other category was associated with only 20% congruent Stroop trials and 80% incongruent Stroop trials. As predicted, participants selected the low-conflict category more frequently, indicating that participants avoid contexts with high-conflict likelihood. Furthermore, we predicted a correlation between this preference for the low-conflict category and the control implementation associated with the categories (i.e., context-specific proportion congruency effect, CSPC effect). Results however did not show such a correlation, thereby failing to support a relationship between context control and context selection. Copyright © 2013 Elsevier B.V. All rights reserved.

    2013-01-01

    International audience; We present an emotion ontology for describing and reasoning on emotion context in order to improve emotion detection based on bodily expression. We incorporate context into the two-factor theory of emotion (bodily reaction plus cognitive input) and demonstrate the importance of context in the emotion experience. In attempting to determine emotion felt by another person, the bodily expresson of their emotion is the only evidence directly available, eg, ''John looks angr...

    2013-01-01

    Full Text Available The context refers to “any information that can be used to characterize the situation of an entity, where an entity can be a person, place, or physical object.” Radio context awareness is defined as the ability of detecting and estimating a system state or parameter, either globally or concerning one of its components, in a radio system for enhancing performance at the physical, network, or application layers. In this paper, we review the fundamentals of context awareness and the recent advances in the main radio techniques that increase the context awareness and smartness, posing challenges and renewed opportunities to added-value applications in the context of the next generation of wireless networks.

    2012-04-01

    To truly understand context and apply it in business intelligence, it is vital to understand what context is and how it can be applied in addressing organizational needs. Context describes the facets of the environment that impact the way that end users interact with the system. Context includes aspects of location, chronology, access method, demographics, social influence/ relationships, end-user attitude/ emotional state, behavior/ past behavior, and presence. To be successful in making Business Intelligence content enabled, it is important to be able to capture the context of use user. With advances in technology, there are a number of ways in which this user based information can be gathered and exposed to enhance the overall end user experience.

    Context effects in recognition tests are twofold. First, presenting familiar contexts at a test leads to an attribution of context familiarity to a recognition probe, which has been dubbed ‘context-dependent recognition’. Second, reinstating the exact study context for a particular target in a recognition test cues recollection of an item-context association, resulting in ‘context-dependent discrimination’. Here we investigated how these two context effects are expressed in metacognitive moni...

    Jain, Rajshree; Tyagi, Jaya; Singh, Sandeep Kumar; Alam, Taj

    2017-10-01

    Recommender systems and context awareness is currently a vital field of research. Most hybrid recommendation systems implement content based and collaborative filtering techniques whereas this work combines context and collaborative filtering. The paper presents a hybrid context aware recommender system for books and movies that gives recommendations based on the user context as well as user or item similarity. It also addresses the issue of dimensionality reduction using weighted pre filtering based on dynamically entered user context and preference of context. This unique step helps to reduce the size of dataset for collaborative filtering. Bias subtracted collaborative filtering is used so as to consider the relative rating of a particular user and not the absolute values. Cosine similarity is used as a metric to determine the similarity between users or items. The unknown ratings are calculated and evaluated using MSE (Mean Squared Error) in test and train datasets. The overall process of recommendation has helped to personalize recommendations and give more accurate results with reduced complexity in collaborative filtering.

    2017-05-01

    The Internet of Things envisions a web-connected infrastructure of billions of sensors and actuation devices. However, the current state-of-the-art presents another reality: monolithic end-to-end applications tightly coupled to a limited set of sensors and actuators. Growing such applications with new devices or behaviors, or extending the existing infrastructure with new applications, involves redesign and redeployment. We instead propose a modular approach to these applications, breaking them into an equivalent set of functional units (context engines) whose input/output transformations are driven by general-purpose machine learning, demonstrating an improvement in compute redundancy and computational complexity with minimal impact on accuracy. In conjunction with formal data specifications, or ontologies, we can replace application-specific implementations with a composition of context engines that use common statistical learning to generate output, thus improving context reuse. We implement interconnected context-aware applications using our approach, extracting user context from sensors in both healthcare and grid applications. We compare our infrastructure to single-stage monolithic implementations with single-point communications between sensor nodes and the cloud servers, demonstrating a reduction in combined system energy by 22-45%, and multiplying the battery lifetime of power-constrained devices by at least 22x, with easy deployment across different architectures and devices.

    Full Text Available The primary thrust of this work is to demonstrate the applicability of association rule mining in public health domain, focusing on physical activity and exercising. In this paper, the concept of association rule mining is shown assisting to promote the physical exercise as regular human activity. Specifically, similar to the prototypical example of association rule mining, market basket analysis, our proposed novel approach considers two events – exercise (sporadic and sleep (regular as the two items of the frequent set; and associating the former, exercise event, with latter, the daily occurring activity sleep at night, helps strengthening the frequency of the exercise patterns. The regularity can further be enhanced, if the exercising instruments are kept in the vicinity of the bed and are within easy reach.

  7. Human reliability assessment in context

    International Nuclear Information System (INIS)

    Hollnagel, Erik

    2005-01-01

    Human Reliability Assessment (HRA) is conducted on the unspoken premise that 'human error' is a meaningful concept and that it can be associated with individual actions. The basis for this assumption it found in the origin of HRA, as a necessary extension of PSA to account for the impact of failures emanating from human actions. Although it was natural to model HRA on PSA, a large number of studies have shown that the premises are wrong, specifically that human and technological functions cannot be decomposed in the same manner. The general experience from accident studies also indicates that action failures are a function of the context, and that it is the variability of the context rather than the 'human error probability' that is the much sought for signal. Accepting this will have significant consequences for the way in which HRA, and ultimately also PSA, should be pursued

    2004-12-01

    Despite the rapid development of cyber technologies, today we still have very limited attention and communication bandwidth to process the increasing information flow. The goal of the study is to develop a context-aware filter to match the information load with particular needs and capacities. The functions include bandwidth-resolution trade-off and user context modeling. From the empirical lab studies, it is found that the resolution of images can be reduced in order of magnitude if the viewer knows that he/she is looking for particular features. The adaptive display queue is optimized with real-time operational conditions and user's inquiry history. Instead of measuring operator's behavior directly, ubiquitous computing models are developed to anticipate user's behavior from the operational environment data. A case study of the video stream monitoring for transit security is discussed in the paper. In addition, the author addresses the future direction of coherent human-machine vision systems.

  14. Creating a Context for Chemistry

    Science.gov (United States)

    Truman Schwartz, A.

    Until relatively recently, the teaching of chemistry at the college and university level in the United States has been quite traditional and oriented primarily toward the preparation of chemists. Students not concentrating in the sciences have often been poorly served by existing courses. Chemistry in Context: Applying Chemistry to Society, a textbook for nonscience majors developed under the sponsorship of the American Chemical Society, is an effort to address the needs and interests of this audience. The book introduces the phenomena and principles of chemistry within the context of socially significant issues such as global warming, ozone depletion, alternate energy sources, nutrition, and genetic engineering. The chemistry is presented as needed to inform an understanding of the central topics, and the text features student-centered activities designed to promote critical thinking and risk-benefit analysis as well as an understanding of chemical principles. This paper summarizes the origin, development, content, pedagogy, evaluation, and influence of Chemistry in Context and considers its potential implications for other disciplines and the instruction of science majors.

  15. Doing classical theology in context

    Directory of Open Access Journals (Sweden)

    Gerrit Neven

    2007-05-01

    Full Text Available This article is about doing classical theology in context. The weight of my argument is that classical text of Karl Barth’s theology is great intellectual text means: being addressed by this text in the context in which one lives. The basic keywords that constitute a rule for reading those texts are “equality”, “event” and “re-contextualisation”. The article contains two sections: The first section elaborates statements about the challenge of the event and the project of rereading classics by way of recontextualisation. The word “event” refers to true and innovating moments in history which one can share, or which one can betray. Classical texts always share in those liberative moments. The question then is in what sense do they present a challenge to the contemporary reader. The second section elaborates the position of man as central and all decisive for doing theology in context now. In this section, the author appeals for a renewal of the classical anthropology as an anthropology of hope. This anthropology contradicts postmodern concepts of otherness.

    Full Text Available Context aware applications, which can adapt their behaviors to changing environments, are attracting more and more attention. To simplify the complexity of developing applications, context aware middleware, which introduces context awareness into the traditional middleware, is highlighted to provide a homogeneous interface involving generic context management solutions. This paper provides a survey of state-of-the-art context aware middleware architectures proposed during the period from 2009 through 2015. First, a preliminary background, such as the principles of context, context awareness, context modelling, and context reasoning, is provided for a comprehensive understanding of context aware middleware. On this basis, an overview of eleven carefully selected middleware architectures is presented and their main features explained. Then, thorough comparisons and analysis of the presented middleware architectures are performed based on technical parameters including architectural style, context abstraction, context reasoning, scalability, fault tolerance, interoperability, service discovery, storage, security & privacy, context awareness level, and cloud-based big data analytics. The analysis shows that there is actually no context aware middleware architecture that complies with all requirements. Finally, challenges are pointed out as open issues for future work.

  19. Internet of Thing Context Awareness Model

    Directory of Open Access Journals (Sweden)

    Derrick Ntalasha

    2016-02-01

    Full Text Available This paper aims to address key concept of context awareness in the Internet of Things (IoT domain by providing a model that proactively monitors behaviour of devices and services. This concept represents context into two types of information representation, namely set based and mark-up based ontology for the purpose of defining a context awareness model that accurately represent context in IoT. The context model is defined using Resources, Actors, Ambients and Policies. The model adds value to the next stage of IoT evolution by using context ambients to bring about predictive and proactive modelling in understanding context and context awareness. IoT context is represented using the hierarchical hybrid context model. This model provides a method of representing contexts based on context quality and availability in an entity relation hierarchy form. The model is exemplified using the context management application based on agents. Experimental results indicate that context awareness in the Internet of Things can be enhanced by the proposed model.

These results have been confirmed and extended in human neuroimaging to encompass secondary rewards more unique to humans, such as money. The majority of the extant literature covers the brain areas associated with rewards whilst neglecting analysis of the actual behaviours that these rewards generate. This review strives to redress this imbalance by illustrating the importance of looking at the behavioural outcome of rewards and the context in which they are produced. Following a brief review of the literature of reward-related activity in the brain, we examine the effect of reward context on actions. These studies reveal how the presence of reward vs. reward and punishment, or being conscious vs. unconscious of reward-related actions, differentially influence behaviour. The latter finding is of particular importance given the extent to which animal models are used in understanding the reward systems of the human mind. It is clear that further studies are needed to learn about the human reaction to reward in its entirety, including any distinctions between conscious and unconscious behaviours. We propose that studies of reward entail a measure of the animal's (human or nonhuman knowledge of the reward and knowledge of its own behavioural outcome to achieve that reward.

    Full Text Available There are few studies that focus on the influence that contextual aspects have in marital satisfaction (Meléndez, Aleixandre,& Saez, 1993.However, nowadays the reasons for a divorce are related to the actual social situation (Khalfani-Cox, 2009. Thus, the aim of this study is to identify contextual aspects that are associ-ated with marital satisfaction; in order to accomplish this objective, we conducted two studies. The purpose of the first study was to identify recent context aspects that influence marital satisfaction throughout an open question, which was ap-plied to 131 people. The results indicate that the dimensions of economic, labor time, home safety, stress in the environment, and the place where they live influ-ence marital satisfaction. In the second study, based on the information obtained previously, we formed indicators that were applied together with a scale of mari-tal satisfaction to105 couples. The results show that the context is closely related to marital satisfaction. In addition, the results determine that men give greater importance to the economic and employment situation than women do. Overall, this study indicates that sex differences prove that the roles and cultural expecta-tions have remained in the dynamics of the relationship and thus influence the assessment of marital satisfaction.

  6. Context Representation and Fusion: Advancements and Opportunities

    Full Text Available The acceptance and usability of context-aware systems have given them the edge of wide use in various domains and has also attracted the attention of researchers in the area of context-aware computing. Making user context information available to such systems is the center of attention. However, there is very little emphasis given to the process of context representation and context fusion which are integral parts of context-aware systems. Context representation and fusion facilitate in recognizing the dependency/relationship of one data source on another to extract a better understanding of user context. The problem is more critical when data is emerging from heterogeneous sources of diverse nature like sensors, user profiles, and social interactions and also at different timestamps. Both the processes of context representation and fusion are followed in one way or another; however, they are not discussed explicitly for the realization of context-aware systems. In other words most of the context-aware systems underestimate the importance context representation and fusion. This research has explicitly focused on the importance of both the processes of context representation and fusion and has streamlined their existence in the overall architecture of context-aware systems’ design and development. Various applications of context representation and fusion in context-aware systems are also highlighted in this research. A detailed review on both the processes is provided in this research with their applications. Future research directions (challenges are also highlighted which needs proper attention for the purpose of achieving the goal of realizing context-aware systems.

    Full Text Available In this paper, the author examines the regional context of Croatian politics, highlighting the main reasons for its significance: involvement of the region in war in recent history, the rootedness, aside from that, of extremely strong economic, political and cultural bonds between the countries in the region, and the importance of cooperation in the region for EU accession and further economic development. On these grounds, the author seeks to examine the possibility for stabilisation of the region, and to establish what interests the neighbouring countries such as Italy, Austria, Hungary and others have in strenghtening the bonds with the new democracies in Central and Southeast Europe. All of this eventually provides the answer to the question what is the interest of the EU in this region’s stability and in its admission to the European Union

    Full Text Available This article is based on the importance of using virtual tours in schools as a means to disseminate local cultural heritage, school projects and teaching resources. We want to use virtual tours, involving the school community in its use, through the production of relevant multimedia content as a way to understand and analyze the potential of multimedia resources in schools. With the evolution of new technologies, including the internet, it is up to the schools, as sources of knowledge transmission, to resort to new technologies as a way to encourage students to learn, to promote local heritage and to disclose the work of the school community, using virtual tours in school context as a powerful interdisciplinary technical and educational resource.

  4. Hierarchical Context Modeling for Video Event Recognition.

    Wang, Xiaoyang; Ji, Qiang

    2016-10-11

    Current video event recognition research remains largely target-centered. For real-world surveillance videos, targetcentered event recognition faces great challenges due to large intra-class target variation, limited image resolution, and poor detection and tracking results. To mitigate these challenges, we introduced a context-augmented video event recognition approach. Specifically, we explicitly capture different types of contexts from three levels including image level, semantic level, and prior level. At the image level, we introduce two types of contextual features including the appearance context features and interaction context features to capture the appearance of context objects and their interactions with the target objects. At the semantic level, we propose a deep model based on deep Boltzmann machine to learn event object representations and their interactions. At the prior level, we utilize two types of prior-level contexts including scene priming and dynamic cueing. Finally, we introduce a hierarchical context model that systematically integrates the contextual information at different levels. Through the hierarchical context model, contexts at different levels jointly contribute to the event recognition. We evaluate the hierarchical context model for event recognition on benchmark surveillance video datasets. Results show that incorporating contexts in each level can improve event recognition performance, and jointly integrating three levels of contexts through our hierarchical model achieves the best performance.

  5. Use of Context in Video Processing

    Science.gov (United States)

    Wu, Chen; Aghajan, Hamid

    Interpreting an event or a scene based on visual data often requires additional contextual information. Contextual information may be obtained from different sources. In this chapter, we discuss two broad categories of contextual sources: environmental context and user-centric context. Environmental context refers to information derived from domain knowledge or from concurrently sensed effects in the area of operation. User-centric context refers to information obtained and accumulated from the user. Both types of context can include static or dynamic contextual elements. Examples from a smart home environment are presented to illustrate how different types of contextual data can be applied to aid the decision-making process.

    2015-01-02

    In contemporary music therapy as well as in related interdisciplinary fields, the importance of context in relation to theory, research, and practice has been emphasized. However, the word context seems to be used in several different ways and conceptualizations of contextual approaches vary too. The objective of this theoretical article is to clarify traditions of language use in relation to context in music therapy. In reviewing and discussing the literature, we focus on the field of mental health care. When discussing issues related to context, this literature partly focuses on the surroundings of music therapy practice, partly on the ecology of reciprocal influences within and between situations or systems. On this basis, three types of context awareness in music therapy are identified: music therapy in context; music therapy as context; and music therapy as interacting contexts. The identified types of context awareness are exemplified through references to music therapy literature and then discussed in relation to two very different metaphors, namely context as frame and context as link. Implications for practice, research, and theory development in music therapy are suggested.

    2017-07-01

    A Gibbs Sampler based topic model for image annotation, which takes into account the interaction between visual geometric context and related topic, is presented. Most of the existing topic models for scene annotation use segmentation-based algorithm. However, topic models using segmentation algorithm alone sometimes can produce erroneous results when used to annotate real-life scene pictures. Therefore, our algorithm makes use of peaks of image surface instead of segmentation regions. Existing approaches use SIFT algorithm and treat the peaks as round blob features. In this paper, the peaks are treated as anisotropic blob features, which models low level visual elements more precisely. In order to better utilize visual features, our model not only takes into consideration visual codeword, but also considers influence of visual properties to topic formation, such as orientation, width, length and color. The basic idea is based on the assumption that different topics will produce distinct visual appearance, and different visual appearance is helpful to distinguish topics. During the learning stage, each topic will be associated with a set of distributions of visual properties, which depicts appearance of the topic. This paper considers more geometric properties, which will reduce topic uncertainty and learn the images better. Tested with Corel5K, SAIAPR-TC12 and Espgame100k Datasets, our method performs moderately better than some state of the arts methods.

  9. Vygotsky's Crisis: Argument, context, relevance.

    2012-06-01

    Vygotsky's The Historical Significance of the Crisis in Psychology (1926-1927) is an important text in the history and philosophy of psychology that has only become available to scholars in 1982 in Russian, and in 1997 in English. The goal of this paper is to introduce Vygotsky's conception of psychology to a wider audience. I argue that Vygotsky's argument about the "crisis" in psychology and its resolution can be fully understood only in the context of his social and political thinking. Vygotsky shared the enthusiasm, widespread among Russian leftist intelligentsia in the 1920s, that Soviet society had launched an unprecedented social experiment: The socialist revolution opened the way for establishing social conditions that would let the individual flourish. For Vygotsky, this meant that "a new man" of the future would become "the first and only species in biology that would create itself." He envisioned psychology as a science that would serve this humanist teleology. I propose that The Crisis is relevant today insofar as it helps us define a fundamental problem: How can we systematically account for the development of knowledge in psychology? I evaluate how Vygotsky addresses this problem as a historian of the crisis. Copyright © 2011 Elsevier Ltd. All rights reserved.

  10. Health Inequalities in Global Context

    Beckfield, Jason; Olafsdottir, Sigrun

    2017-01-01

    The existence of social inequalities in health is well established. One strand of research focuses on inequalities in health within a single country. A separate and newer strand of research focuses on the relationship between inequality and average population health across countries. Despite the theorization of (presumably variable) social conditions as “fundamental causes” of disease and health, the cross-national literature has focused on average, aggregate population health as the central outcome. Controversies currently surround macro-structural determinants of overall population health such as income inequality. We advance and redirect these debates by conceptualizing inequalities in health as cross-national variables that are sensitive to social conditions. Using data from 48 World Values Survey countries, representing 74% of the world’s population, we examine cross-national variation in inequalities in health. The results reveal substantial variation in health inequalities according to income, education, sex, and migrant status. While higher socioeconomic position is associated with better self-rated health around the globe, the size of the association varies across institutional context, and across dimensions of stratification. There is some evidence that education and income are more strongly associated with self-rated health than sex or migrant status. PMID:29104292

    We summarize methods and plans to monitor and calibrate photometric observations with our autonomous, robotic network of 2m, 1m and 40cm telescopes. These are sited globally to optimize our ability to observe time-variable sources. Wide field "context" cameras are aligned with our network telescopes and cycle every ˜2 minutes through BVr'i'z' filters, spanning our optical range. We measure instantaneous zero-point offsets and transparency (throughput) against calibrators in the 5-12m range from the all-sky Tycho2 catalog, and periodically against primary standards. Similar measurements are made for all our science images, with typical fields of view of ˜0.5 degrees. These are matched against Landolt, Stetson and Sloan standards, and against calibrators in the 10-17m range from the all-sky APASS catalog. Such measurements provide pretty good instantaneous flux calibration, often to better than 5%, even in cloudy conditions. Zero-point and transparency measurements can be used to characterize, monitor and inter-compare sites and equipment. When accurate calibrations of Target against Standard fields are required, monitoring measurements can be used to select truly photometric periods when accurate calibrations can be automatically scheduled and performed.

    2014-05-01

    Full Text Available In a recent paper (M. Barash, A. Okhotin, "Defining contexts in context-free grammars", LATA 2012, the authors introduced an extension of the context-free grammars equipped with an operator for referring to the left context of the substring being defined. This paper proposes a more general model, in which context specifications may be two-sided, that is, both the left and the right contexts can be specified by the corresponding operators. The paper gives the definitions and establishes the basic theory of such grammars, leading to a normal form and a parsing algorithm working in time O(n^4, where n is the length of the input string.

    2012-01-01

    Full Text Available This paper proposes a methodology for sensor data interpretation that can combine sensor outputs with contexts represented as sets of annotated business rules. Sensor readings are interpreted to generate events labeled with the appropriate type and level of uncertainty. Then, the appropriate context is selected. Reconciliation of different uncertainty types is achieved by a simple technique that moves uncertainty from events to business rules by generating combs of standard Boolean predicates. Finally, context rules are evaluated together with the events to take a decision. The feasibility of our idea is demonstrated via a case study where a context-reasoning engine has been connected to simulated heartbeat sensors using prerecorded experimental data. We use sensor outputs to identify the proper context of operation of a system and trigger decision-making based on context information.

  19. Context and Crossmodal Interactions: An ERP Study

    Directory of Open Access Journals (Sweden)

    Beatriz R Sarmiento

    2011-10-01

    Full Text Available In a previous behavioural study, we reported that a particular context of stimulus congruency influenced audiovisual interactions. In particular, audiovisual interaction, measured in terms of congruency effect, was reduced when a high proportion of incongruent trials was presented. We argued that this modulation was due to changes in participants' control set as a function of the context of congruency, with greater control applied when most of the trials were incongruent. Since behavioural data do not allow to specify the level at which control was affecting audiovisual interaction, we conducted an event-related potentials (ERPs study to further investigate each context of audiovisual congruency. Participants performed an audiovisual congruency task, where the stimulus onset could be present on two different contexts mixed at random: a high proportion congruent context and a low proportion congruent context. The context manipulation was found to modulate brain ERPs related to perceptual and response selection processes, ie, the N2 and P3 components. The N2 amplitude was larger for the less common trials on both high and low congruent proportion contexts, while the P3 amplitude and latency were differentially modulated by incongruent trials on the two contexts.

  20. Context-dependent memory and mood

    OpenAIRE

    Løhre, Erik

    2011-01-01

    This thesis examined the effects of affective state (mood) on context-dependent memory. In the so-called context-change paradigm, participants learn two lists of words, and their internal context is either changed or kept constant between the two lists. The usual finding in this paradigm is that participants remember fewer words from the first list, but more words from the second list when context is changed compared to when it is kept constant. To see whether these effects are influenced by ...

    This paper presents recent data on the performance of 247 middle school students on questions concerning average in three contexts. Analysis includes considering levels of understanding linking definition and context, performance across contexts, the relative difficulty of tasks, and difference in performance for male and female students. The outcomes lead to a discussion of the expectations of the curriculum and its implementation, as well as assessment, in relation to students' skills in carrying out procedures and their understanding about the meaning of average in context.

  2. New Historicism: Text and Context

    Directory of Open Access Journals (Sweden)

    Violeta M. Vesić

    2016-02-01

    Full Text Available During most of the twentieth century history was seen as a phenomenon outside of literature that guaranteed the veracity of literary interpretation. History was unique and it functioned as a basis for reading literary works. During the seventies of the twentieth century there occurred a change of attitude towards history in American literary theory, and there appeared a new theoretical approach which soon became known as New Historicism. Since its inception, New Historicism has been identified with the study of Renaissance and Romanticism, but nowadays it has been increasingly involved in other literary trends. Although there are great differences in the arguments and practices at various representatives of this school, New Historicism has clearly recognizable features and many new historicists will agree with the statement of Walter Cohen that New Historicism, when it appeared in the eighties, represented something quite new in reference to the studies of theory, criticism and history (Cohen 1987, 33. Theoretical connection with Bakhtin, Foucault and Marx is clear, as well as a kind of uneasy tie with deconstruction and the work of Paul de Man. At the center of this approach is a renewed interest in the study of literary works in the light of historical and political circumstances in which they were created. Foucault encouraged readers to begin to move literary texts and to link them with discourses and representations that are not literary, as well as to examine the sociological aspects of the texts in order to take part in the social struggles of today. The study of literary works using New Historicism is the study of politics, history, culture and circumstances in which these works were created. With regard to one of the main fact which is located in the center of the criticism, that history cannot be viewed objectively and that reality can only be understood through a cultural context that reveals the work, re-reading and interpretation of

  9. Harnessing Context for Vandalism Detection in Wikipedia

    Directory of Open Access Journals (Sweden)

    Lakshmish Ramaswamy

    2014-05-01

    Full Text Available The importance of collaborative social media (CSM applications such as Wikipedia to modern free societies can hardly be overemphasized. By allowing end users to freely create and edit content, Wikipedia has greatly facilitated democratization of information. However, over the past several years, Wikipedia has also become susceptible to vandalism, which has adversely affected its information quality. Traditional vandalism detection techniques that rely upon simple textual features such as spammy or abusive words have not been very effective in combating sophisticated vandal attacks that do not contain common vandalism markers. In this paper, we propose a context-based vandalism detection framework for Wikipedia. We first propose a contextenhanced finite state model for representing the context evolution ofWikipedia articles. This paper identifies two distinct types of context that are potentially valuable for vandalism detection, namely content-context and contributor-context. The distinguishing powers of these contexts are discussed by providing empirical results. We design two novel metrics for measuring how well the content-context of an incoming edit fits into the topic and the existing content of a Wikipedia article. We outline machine learning-based vandalism identification schemes that utilize these metrics. Our experiments indicate that utilizing context can substantially improve vandalism detection accuracy.

    Pointer, S C; Bond, N W

    1998-06-01

    An olfactory stimulus and a visual stimulus were employed in a context-dependent memory study using a prose passage as the to-be-remembered item. Ninety-five university students (aged 17-35 years) learned the passage of prose in the presence of one of the stimuli and were then asked to recall the passage with the original context either reinstated or not reinstated. The results revealed a significant context-dependent memory effect for the olfactory cue but not for the visual cue. They demonstrate support for the effectiveness of odours as context cues and it is suggested that context-dependent memory processes may underlie the formation and retrieval of odour-evoked autobiographical memories.

    2009-06-01

    Full Text Available Location- and context-aware services are emerging technologies in mobile and desktop environments, however, most of them are difficult to use and do not seem to be beneficial enough. Our research focuses on designing and creating a service-oriented framework that helps location- and context-aware, client-service type application development and use. Location information is combined with other contexts such as the users' history, preferences and disabilities. The framework also handles the spatial model of the environment (e.g. map of a room or a building as a context. The framework is built on a semantic backend where the ontologies are represented using the OWL description language. The use of ontologies enables the framework to run inference tasks and to easily adapt to new context types. The framework contains a compatibility layer for positioning devices, which hides the technical differences of positioning technologies and enables the combination of location data of various sources.

  3. Context awareness and sensitivity in SEA implementation

    International Nuclear Information System (INIS)

    Hilding-Rydevik, Tuija; Bjarnadottir, Holmfridur

    2007-01-01

    The Impact Assessment research community repeatedly asserts that the implementation of Strategic Environmental Assessment (SEA) should take the issue of context into consideration. The primary aim of this paper then is to attempt to give substance to the concept of 'context' in relation to the implementation of SEA. The second aim is to discuss the relevance of context consciousness and sensitivity in relation to one of the main aims given to SEA implementation i.e. to contribute to the 'integration' of environmental perspectives in planning processes. Context must be defined in relation to a certain question. In this paper the question in focus is the assumption that SEA implementation will contribute to integration of environmental issues in planning processes. Research results relating to the use of environmental tools, like for example SEA, and experiences of integration efforts, strongly indicate that the use of a single tool like SEA is not enough to achieve this integration. The current 'context free' normative and procedural assumptions concerning the aim of SEA implementation and 'best practice' in term of SEA can be criticised on the same grounds as normative and procedural planning theories, as being context free. The assumptions behind the current formulations of the aim and best practice of SEA need to be revisited. A firm empirical and theoretical knowledge and discussion is needed, especially in relation to the issue of context and integration. This paper provides a starting point in this direction

  6. Extinction produces context inhibition and multiple-context extinction reduces response recovery in human predictive learning.

    Science.gov (United States)

    Glautier, Steven; Elgueta, Tito; Nelson, James Byron

    2013-12-01

    Two experiments with human participants were used to investigate recovery of an extinguished learned response after a context change using ABC designs. In an ABC design, the context changes over the three successive stages of acquisition (context A), extinction (context B), and test (context C). In both experiments, we found reduced recovery in groups that had extinction in multiple contexts, and that the extinction contexts acquired inhibitory strength. These results confirm those of previous investigations, that multiple-context extinction can produce less response recovery than single-context extinction, and they also provide new evidence for the involvement of contextual inhibitory processes in extinction in humans. The foregoing results are broadly in line with a protection-from-extinction account of response recovery. Yet, despite the fact that we detected contextual inhibition, predictions based on protection-from-extinction were not fully reliable for the single- and multiple-context group differences that we observed in (1) rates of extinction and (2) the strength of context inhibition. Thus, although evidence was obtained for a protection-from-extinction account of response recovery, this account can not explain all of the data.

  7. Leadership in entrepreneurial organizations: context and motives.

    Martí Ripoll, Margarita; Gil Rodríguez, Francisco; Barrasa, Angel; Antino, Mirko

    2010-11-01

    Although organizational contexts have an influence on leadership, and some of their characteristics may facilitate (through weak structures) or inhibit (through strong structures) the leaders' behaviors, the extent of their influence has rarely been studied. Indeed, research of the influence of some types of contexts (entrepreneurial vs. non-entrepreneurial) on the emergence of certain variables (leaders' motives) is even scarcer. This paper analyses this influence in 40 companies, interviewing their leaders to obtain a qualitative register of their motives, and administering questionnaires to members of their respective management teams. The hypothesis considered was that, in 'weak' contexts (entrepreneurial), the leaders' motives would be more salient than in 'strong' contexts (non-entrepreneurial). The results largely confirm this hypothesis with respect to behaviors that are directly related to three main motives (power, affiliation and achievement). These results are discussed, and practical suggestions are provided for future research.

  14. Effect of study context on item recollection.

    Science.gov (United States)

    Skinner, Erin I; Fernandes, Myra A

    2010-07-01

    We examined how visual context information provided during encoding, and unrelated to the target word, affected later recollection for words presented alone using a remember-know paradigm. Experiments 1A and 1B showed that participants had better overall memory-specifically, recollection-for words studied with pictures of intact faces than for words studied with pictures of scrambled or inverted faces. Experiment 2 replicated these results and showed that recollection was higher for words studied with pictures of faces than when no image accompanied the study word. In Experiment 3 participants showed equivalent memory for words studied with unique faces as for those studied with a repeatedly presented face. Results suggest that recollection benefits when visual context information high in meaningful content accompanies study words and that this benefit is not related to the uniqueness of the context. We suggest that participants use elaborative processes to integrate item and meaningful contexts into ensemble information, improving subsequent item recollection.

  15. Urbanism, Neighborhood Context, and Social Networks.

    Science.gov (United States)

    Cornwell, Erin York; Behler, Rachel L

    2015-09-01

    Theories of urbanism suggest that the urban context erodes individuals' strong social ties with friends and family. Recent research has narrowed focus to the neighborhood context, emphasizing how localized structural disadvantage affects community-level cohesion and social capital. In this paper, we argue that neighborhood context also shapes social ties with friends and family- particularly for community-dwelling seniors. We hypothesize that neighborhood disadvantage, residential instability, and disorder restrict residents' abilities to cultivate close relationships with neighbors and non-neighbor friends and family. Using data from the National Social Life, Health, and Aging Project (NSHAP), we find that older adults who live in disadvantaged neighborhoods have smaller social networks. Neighborhood disadvantage is also associated with less close network ties and less frequent interaction - but only among men. Furthermore, residents of disordered neighborhoods have smaller networks and weaker ties. We urge scholars to pay greater attention to how neighborhood context contributes to disparities in network-based access to resources.

  16. Context: The strategic management Rosetta Stone

    Directory of Open Access Journals (Sweden)

    R. V. Weeks

    2007-12-01

    Full Text Available Purpose: The purpose of this paper is to analyse context as a means for interpreting and making sense of evolving strategic management theory and practice. Problem investigated: Traditional strategic management theory based on rational deductive methodologies assumes contextual predictability, yet contemporary conditions tend to contradict this assumption. In response, alternative theories and practices for dealing with complex contexts have emerged (Brews & Purohit, 2006; Grant, 2003; Kurt & Snowden, 2003and Stacey, 1995. Methodology: A literature study was undertaken to determine the nature of emergent strategic management theory and practice, in response to contextual complexity and how it differs from traditional practice (Mintzberg, 1994 and Weeks &Lessing, 1993. Findings: An important conclusion drawn from the study is that context acts as a determinant for making sense of the evolution of strategic management theory and practice. While traditional strategic management practice still assumes relevance in contexts of linear causality, it breaks down in complex contexts. Emergent strategic management theory, based on complex adaptive systems, is increasingly assuming relevance. Notably, many institutions are still attempting to make use of scenario planning in an attempt to deal with contextual complexity, a practice not supported by leading researchers(Stacey, 1995 and Kurt & Snowden, 2003. Value of the research: The insights gained from the study assume relevance, in view of the contextual complexity confronting modern-day institutions. The findings suggest that emergent strategy based on complex adaptive system theory needs to be considered as a means for dealing with increasing environmental turbulence. Conclusion: It is concluded that context serves as the Rosetta stone for making sense of strategic management theory and practice. In view of the research findings, as reflected in the literature, it would seem that the use of complex

  19. The attentional boost effect and context memory.

    Science.gov (United States)

    Mulligan, Neil W; Smith, S Adam; Spataro, Pietro

    2016-04-01

    Stimuli co-occurring with targets in a detection task are better remembered than stimuli co-occurring with distractors-the attentional boost effect (ABE). The ABE is of interest because it is an exception to the usual finding that divided attention during encoding impairs memory. The effect has been demonstrated in tests of item memory but it is unclear if context memory is likewise affected. Some accounts suggest enhanced perceptual encoding or associative binding, predicting an ABE on context memory, whereas other evidence suggests a more abstract, amodal basis of the effect. In Experiment 1, context memory was assessed in terms of an intramodal perceptual detail, the font and color of the study word. Experiment 2 examined context memory cross-modally, assessing memory for the modality (visual or auditory) of the study word. Experiments 3 and 4 assessed context memory with list discrimination, in which 2 study lists are presented and participants must later remember which list (if either) a test word came from. In all experiments, item (recognition) memory was also assessed and consistently displayed a robust ABE. In contrast, the attentional-boost manipulation did not enhance context memory, whether defined in terms of visual details, study modality, or list membership. There was some evidence that the mode of responding on the detection task (motoric response as opposed to covert counting of targets) may impact context memory but there was no evidence of an effect of target detection, per se. In sum, the ABE did not occur in context memory with verbal materials. (c) 2016 APA, all rights reserved).

  2. Canonical, stable, general mapping using context schemes.

    Science.gov (United States)

    Novak, Adam M; Rosen, Yohei; Haussler, David; Paten, Benedict

    2015-11-15

    Sequence mapping is the cornerstone of modern genomics. However, most existing sequence mapping algorithms are insufficiently general. We introduce context schemes: a method that allows the unambiguous recognition of a reference base in a query sequence by testing the query for substrings from an algorithmically defined set. Context schemes only map when there is a unique best mapping, and define this criterion uniformly for all reference bases. Mappings under context schemes can also be made stable, so that extension of the query string (e.g. by increasing read length) will not alter the mapping of previously mapped positions. Context schemes are general in several senses. They natively support the detection of arbitrary complex, novel rearrangements relative to the reference. They can scale over orders of magnitude in query sequence length. Finally, they are trivially extensible to more complex reference structures, such as graphs, that incorporate additional variation.

  3. Effects of a Context Shift and Multiple Context Extinction on Reactivity to Alcohol Cues

    2008-01-01

    Cue exposure treatment (CET) attempts to reduce the influence of conditioned substance cues on addictive behavior via prolonged cue exposure with response prevention (i.e., extinction), but has received only modest empirical support in clinical trials. This may be because extinction learning appears to be context dependent and a change in context may result in a return of conditioned responding (i.e., renewal), although this has received only limited empirical examination. The current study used a four-session laboratory analogue of CET to examine whether a change in context following three sessions of alcohol cue exposure with response prevention would result in renewal of conditioned responding. In addition, this study examined whether conducting extinction in multiple contexts would attenuate renewal of conditioned responding. In a one-way between-subjects design, 73 heavy drinkers (71% male) were randomized to three conditions: 1) single context extinction (extinction to alcohol cues in the same context for three sessions followed by a context shift at the fourth session); 2) multiple context extinction (extinction to alcohol cues in different contexts each day for all four sessions); and 3) pseudo-extinction control condition (exposure to neutral cues in the same context for three sessions followed by exposure to alcohol cues at the fourth session). The results revealed the predicted cue reactivity and extinction effects, but the hypotheses that a context shift would generate renewed cue reactivity and that multiple contexts would enhance extinction were not supported. Methodological aspects of the study and the need for parametric data on the context dependency of extinction to alcohol cues are discussed. PMID:18729687

  4. Context as a modifier of phraseological meaning

    Directory of Open Access Journals (Sweden)

    Maria Vladimirovna Harlamova

    2014-01-01

    Full Text Available The article is devoted to the problems of actualization of phraseological units in the context of the French youth press. Due to the development of the connotative component of the meaning, phraseological units, as expressive means of the language, are often used in the process of communication to influence the addressee. The phraseological units with positive or negative estimation, expressing emotionally-evaluative attitude of the speaker towards the subject, influence the creation of the pragmatic direction of the utterance. Effected by the context, some changes take place within the structure of phraseological meaning. As the result the pragmatic direction of the text is increased. When a cliché is included into the context, the virtual (pragmatic meaning is substituted by the actual (syntagmatic meaning. Here, two variants of interaction of these meanings are possible. In the first case, the paradigmatic meaning and the syntagmatic meaning can coincide (thus, the phraseological unit is presented in its casual meaning. In the latter case, the meaning of the cliché can be transformed under the influence of the context. It often leads to the divergence between paradigmatic and syntagmatic meanings. Thus, connotative-pragmatic characteristics of any phraseological unit can be defined by the context and it leads to : a a cliché, losing its situational-evaluative feature (influenced by the context, the situational feature disappears and the cliché gets a positive or negative evaluation; b the transition of the cliché to the "oppositely charged" field (phraseological units with negative connotation get positive connotation and vice versa; c the intensification of phraseological meaning. The analyzed examples, proving the influence of the context on phraseological meaning, were taken from various French youth journals.

  15. Context differences in children's ingroup preferences.

    2014-05-01

    Ingroup preferences when deciding who to include in 2 distinct intergroup contexts, gender and school affiliation, were investigated. Children and adolescents, in the 4th (9-10 years) and 8th (13-14 years) grades, chose between including someone in their group who shared their group norm (moral or conventional) or who shared their group membership (school affiliation or gender). With age, children displayed a greater ability to balance information about ingroup norms and group membership. Younger children were more likely to include an outgroup member who supported equal norms than were older children. Accompanying the choices made, there was a greater use of fairness reasoning in younger rather than older participants, and increased references to group identity and group functioning for school identification. There were no differences in ingroup preferences in the school and gender contexts for groups involving moral norms. Desires for equal allocation of resources trumped differences related to ingroup preference. For social-conventional norms, however, there was a greater ingroup preference in a school intergroup context than in a gender intergroup context. Thus, the results demonstrate the importance of context in the manifestation of ingroup preference and the increasing sophistication, with age, of children's and adolescents' group decision-making skills.

  18. Context-Aware HCI Service Selection

    2012-01-01

    Full Text Available Context-awareness has become a key issue in Human-Computer Interaction(HCI to provide better user experience under multi-device and multi-modal environment. With this intuition, we have proposed a web service based framework, which associates interactions with services, and provided service selection mechanism using context knowledge to achieve smart interaction migration [1]. A fundamental problem of such a service-oriented framework for interaction migration is to design an effective while scalable algorithm for service selection. In this paper, we propose a service selection algorithm considering not only context information and user preferences but also inter-service relations such as relative location. Our algorithm detects interaction hot spots within user active scope and presents the best service combination based on evaluation of interaction effectiveness. We also conduct simulation and the results illustrate that our algorithm is effective and scalable for interaction service selection.

  20. Semantic Context Detection Using Audio Event Fusion

    Directory of Open Access Journals (Sweden)

    Cheng Wen-Huang

    2006-01-01

    Full Text Available Semantic-level content analysis is a crucial issue in achieving efficient content retrieval and management. We propose a hierarchical approach that models audio events over a time series in order to accomplish semantic context detection. Two levels of modeling, audio event and semantic context modeling, are devised to bridge the gap between physical audio features and semantic concepts. In this work, hidden Markov models (HMMs are used to model four representative audio events, that is, gunshot, explosion, engine, and car braking, in action movies. At the semantic context level, generative (ergodic hidden Markov model and discriminative (support vector machine (SVM approaches are investigated to fuse the characteristics and correlations among audio events, which provide cues for detecting gunplay and car-chasing scenes. The experimental results demonstrate the effectiveness of the proposed approaches and provide a preliminary framework for information mining by using audio characteristics.

  1. User Experience Evaluation in the Mobile Context

    Science.gov (United States)

    Obrist, Marianna; Meschtscherjakov, Alexander; Tscheligi, Manfred

    Multimedia services on mobile devices are becoming increasingly popular. Whereas the mobile phone is the most likely platform for mobile TV, PDAs, portable game consoles, and music players are attractive alternatives. Mobile TV consumption on mobile phones allows new kinds of user experiences, but it also puts designers and researchers in front of new challenges. On the one hand, designers have to take these novel experience potentials into account. On the other hand, the right methods to collect user feedback to further improve services for the mobile context have to be applied. In this chapter the importance of user experience research for mobile TV within the mobile context is highlighted. We present how different experience levels can be evaluated taking different mobile context categories into account. In particular, we discuss the Experience Sampling Method (ESM), which seems to be a fruitful approach for investigating user TV experiences.

    Present systems and devices are usually protected against different threats concerning digital data processing. The protection mechanisms consume resources, which are either highly limited or intensively utilized by many entities. The optimization of these resources usage is advantageous. The resources that are saved performing optimization may be utilized by other mechanisms or may be sufficient for longer time. It is usually assumed that protection has to provide specific quality and attack resistance. By interpreting context situation of business services - users and services themselves, it is possible to adapt security services parameters to countermeasure threats associated with current situation. This approach leads to optimization of used resources and maintains sufficient security level. This paper presents architecture of adaptive security service, which is context-aware and exploits quality of context data issue.

    The concept of "social self" is often described as a representation of the self-reflected in the eyes or minds of others. Although the appearance of one's own face has substantial social significance for humans, neuroimaging studies have failed to link self-face recognition and the likely neural substrate of the social self, the medial prefrontal cortex (MPFC). We assumed that the social self is recruited during self-face recognition under a rich social context where multiple other faces are available for comparison of social values. Using functional magnetic resonance imaging (fMRI), we examined the modulation of neural responses to the faces of the self and of a close friend in a social context. We identified an enhanced response in the ventral MPFC and right occipitoparietal sulcus in the social context specifically for the self-face. Neural response in the right lateral parietal and inferior temporal cortices, previously claimed as self-face-specific, was unaffected for the self-face but unexpectedly enhanced for the friend's face in the social context. Self-face-specific activation in the pars triangularis of the inferior frontal gyrus, and self-face-specific reduction of activation in the left middle temporal gyrus and the right supramarginal gyrus, replicating a previous finding, were not subject to such modulation. Our results thus demonstrated the recruitment of a social self during self-face recognition in the social context. At least three brain networks for self-face-specific activation may be dissociated by different patterns of response-modulation in the social context, suggesting multiple dynamic self-other representations in the human brain.

    Sensitivity to the regularities and structure contained within sequential, goal-directed actions is an important building block for generating expectations about the actions we observe. Until now, research on statistical learning for actions has solely focused on individual action sequences, but many actions in daily life involve multiple actors in various interaction contexts. The current study is the first to investigate the role of statistical learning in tracking regularities between actions performed by different actors, and whether the social context characterizing their interaction influences learning. That is, are observers more likely to track regularities across actors if they are perceived as acting jointly as opposed to in parallel? We tested adults and toddlers to explore whether social context guides statistical learning and-if so-whether it does so from early in development. In a between-subjects eye-tracking experiment, participants were primed with a social context cue between two actors who either shared a goal of playing together ('Joint' condition) or stated the intention to act alone ('Parallel' condition). In subsequent videos, the actors performed sequential actions in which, for certain action pairs, the first actor's action reliably predicted the second actor's action. We analyzed predictive eye movements to upcoming actions as a measure of learning, and found that both adults and toddlers learned the statistical regularities across actors when their actions caused an effect. Further, adults with high statistical learning performance were sensitive to social context: those who observed actors with a shared goal were more likely to correctly predict upcoming actions. In contrast, there was no effect of social context in the toddler group, regardless of learning performance. These findings shed light on how adults and toddlers perceive statistical regularities across actors depending on the nature of the observed social situation and the

    There is converging evidence that the feeling of conscious recollection is usually accompanied by the bound retrieval of context features of the encoding episode (e.g., Meiser, Sattler, & Weiber, 2008). Recently, however, important limiting conditions have been identified for the binding between context features in memory. For example, focusing on…

  1. Putting retrieval-induced forgetting in context: an inhibition-free, context-based account.

    Science.gov (United States)

    Jonker, Tanya R; Seli, Paul; MacLeod, Colin M

    2013-10-01

    We present a new theoretical account of retrieval-induced forgetting (RIF) together with new experimental evidence that fits this account and challenges the dominant inhibition account. RIF occurs when the retrieval of some material from memory produces later forgetting of related material. The inhibition account asserts that RIF is the result of an inhibition mechanism that acts during retrieval to suppress the representations of interfering competitors. This inhibition is enduring, such that the suppressed material is difficult to access on a later test and is, therefore, recalled more poorly than baseline material. Although the inhibition account is widely accepted, a growing body of research challenges its fundamental assumptions. Our alternative account of RIF instead emphasizes the role of context in remembering. According to this context account, both of 2 tenets must be met for RIF to occur: (a) A context change must occur between study and subsequent retrieval practice, and (b) the retrieval practice context must be the active context during the final test when testing practiced categories. The results of 3 experiments, which directly test the divergent predictions of the 2 accounts, support the context account but cannot be explained by the inhibition account. In an extensive discussion, we survey the literature on RIF and apply our context account to the key findings, demonstrating the explanatory power of context.

  2. Context-Dependent Decay of Motor Memories during Skill Acquisition

    OpenAIRE

    Ingram, James?N.; Flanagan, J.?Randall; Wolpert, Daniel?M.

    2013-01-01

    Summary Current models of motor learning posit that skill acquisition involves both the formation and decay of multiple motor memories that can be engaged in different contexts [1?9]. Memory formation is assumed to be context dependent, so that errors most strongly update motor memories associated with the current context. In contrast, memory decay is assumed to be context independent, so that movement in any context leads to uniform decay across all contexts. We demonstrate that for both obj...

  3. Inferring Human Activity in Mobile Devices by Computing Multiple Contexts.

    This paper introduces a framework for inferring human activities in mobile devices by computing spatial contexts, temporal contexts, spatiotemporal contexts, and user contexts. A spatial context is a significant location that is defined as a geofence, which can be a node associated with a circle, or a polygon; a temporal context contains time-related information that can be e.g., a local time tag, a time difference between geographical locations, or a timespan; a spatiotemporal context is defined as a dwelling length at a particular spatial context; and a user context includes user-related information that can be the user's mobility contexts, environmental contexts, psychological contexts or social contexts. Using the measurements of the built-in sensors and radio signals in mobile devices, we can snapshot a contextual tuple for every second including aforementioned contexts. Giving a contextual tuple, the framework evaluates the posteriori probability of each candidate activity in real-time using a Naïve Bayes classifier. A large dataset containing 710,436 contextual tuples has been recorded for one week from an experiment carried out at Texas A&M University Corpus Christi with three participants. The test results demonstrate that the multi-context solution significantly outperforms the spatial-context-only solution. A classification accuracy of 61.7% is achieved for the spatial-context-only solution, while 88.8% is achieved for the multi-context solution.

    Conditional functional dependencies(CFDs) are important techniques for data consistency.However,CFDs are limited to 1) provide the reasonable values for consistency repairing and 2) detect potential errors.This paper presents context-aware conditional functional dependencies(CCFDs) which contribute to provide reasonable values and detect potential errors.Especially,we focus on automatically discovering minimal CCFDs.In this paper,we present context relativity to measure the relationship of CFDs.The overlap of the related CFDs can provide reasonable values which result in more accuracy consistency repairing,and some related CFDs are combined into CCFDs.Moreover,we prove that discovering minimal CCFDs is NP-complete and we design the precise method and the heuristic method.We also present the dominating value to facilitate the process in both the precise method and the heuristic method.Additionally,the context relativity of the CFDs affects the cleaning results.We will give an approximate threshold of context relativity according to data distribution for suggestion.The repairing results are approved more accuracy,even evidenced by our empirical evaluation.

After pointing to the various definitions of trust that highlight its cognitive, behavioral, and relational groundings, we proceed to examine the aspects of 'social embeddedness' of trust. In this context, we highlight the structural aspect of trust relations, their institutional embeddedness, mediation through cultural meanings, as well as the wider context of social circumstances and limitations. We place a special emphasis on the concept of 'trust culture', its morphogenesis and functions, as well as the significance of trust culture in the context of diminishing the social uncertainty that arises in the situations when trust is demonstrated. Finally, we point to the social functions of trust on the macro level, the functional substitutes for trust, as well as the relationship between trust and social capital.

  8. Hierarchical video summarization based on context clustering

    Tseng, Belle L.; Smith, John R.

    2003-11-01

    A personalized video summary is dynamically generated in our video personalization and summarization system based on user preference and usage environment. The three-tier personalization system adopts the server-middleware-client architecture in order to maintain, select, adapt, and deliver rich media content to the user. The server stores the content sources along with their corresponding MPEG-7 metadata descriptions. In this paper, the metadata includes visual semantic annotations and automatic speech transcriptions. Our personalization and summarization engine in the middleware selects the optimal set of desired video segments by matching shot annotations and sentence transcripts with user preferences. Besides finding the desired contents, the objective is to present a coherent summary. There are diverse methods for creating summaries, and we focus on the challenges of generating a hierarchical video summary based on context information. In our summarization algorithm, three inputs are used to generate the hierarchical video summary output. These inputs are (1) MPEG-7 metadata descriptions of the contents in the server, (2) user preference and usage environment declarations from the user client, and (3) context information including MPEG-7 controlled term list and classification scheme. In a video sequence, descriptions and relevance scores are assigned to each shot. Based on these shot descriptions, context clustering is performed to collect consecutively similar shots to correspond to hierarchical scene representations. The context clustering is based on the available context information, and may be derived from domain knowledge or rules engines. Finally, the selection of structured video segments to generate the hierarchical summary efficiently balances between scene representation and shot selection.

  9. Context-aware modeling of neuronal morphologies

    Directory of Open Access Journals (Sweden)

    Benjamin eTorben-Nielsen

    2014-09-01

    Full Text Available Neuronal morphologies are pivotal for brain functioning: physical overlap between dendrites and axons constrain the circuit topology, and the precise shape and composition of dendrites determine the integration of inputs to produce an output signal. At the same time, morphologies are highly diverse and variant. The variance, presumably, originates from neurons developing in a densely packed brain substrate where they interact (e.g., repulsion or attraction with other actors in this substrate. However, when studying neurons their context is never part of the analysis and they are treated as if they existed in isolation.Here we argue that to fully understand neuronal morphology and its variance it is important to consider neurons in relation to each other and to other actors in the surrounding brain substrate, i.e., their context. We propose a context-aware computational framework, NeuroMaC, in which large numbers of neurons can be grown simultaneously according to growth rules expressed in terms of interactions between the developing neuron and the surrounding brain substrate.As a proof of principle, we demonstrate that by using NeuroMaC we can generate accurate virtual morphologies of distinct classes both in isolation and as part of neuronal forests. Accuracy is validated against population statistics of experimentally reconstructed morphologies. We show that context-aware generation of neurons can explain characteristics of variation. Indeed, plausible variation is an inherent property of the morphologies generated by context-aware rules. We speculate about the applicability of this framework to investigate morphologies and circuits, to classify healthy and pathological morphologies, and to generate large quantities of morphologies for large-scale modeling.

  10. Bilingual Contexts Modulate the Inhibitory Control Network

    Directory of Open Access Journals (Sweden)

    Jing Yang

    2018-03-01

    Full Text Available The present functional magnetic resonance imaging (fMRI study investigated influences of language contexts on inhibitory control and the underlying neural processes. Thirty Cantonese–Mandarin–English trilingual speakers, who were highly proficient in Cantonese (L1 and Mandarin (L2, and moderately proficient in English (L3, performed a picture-naming task in three dual-language contexts (L1-L2, L2-L3, and L1-L3. After each of the three naming tasks, participants performed a flanker task, measuring contextual effects on the inhibitory control system. Behavioral results showed a typical flanker effect in the L2-L3 and L1-L3 condition, but not in the L1-L2 condition, which indicates contextual facilitation on inhibitory control performance by the L1-L2 context. Whole brain analysis of the fMRI data acquired during the flanker tasks showed more neural activations in the right prefrontal cortex and subcortical areas in the L2-L3 and L1-L3 condition on one hand as compared to the L1-L2 condition on the other hand, suggesting greater involvement of the cognitive control areas when participants were performing the flanker task in L2-L3 and L1-L3 contexts. Effective connectivity analyses displayed a cortical-subcortical-cerebellar circuitry for inhibitory control in the trilinguals. However, contrary to the right-lateralized network in the L1-L2 condition, functional networks for inhibitory control in the L2-L3 and L1-L3 condition are less integrated and more left-lateralized. These findings provide a novel perspective for investigating the interaction between bilingualism (multilingualism and inhibitory control by demonstrating instant behavioral effects and neural plasticity as a function of changes in global language contexts.

    Context effects are ubiquitous in speech perception and reflect the ability of human listeners to successfully perceive highly variable speech signals. In the study of how listeners compensate for coarticulatory variability, past studies have used similar effects speech and tone analogues of speech as strong support for speech-neutral, general auditory mechanisms for compensation for coarticulation. In this manuscript, we revisit compensation for coarticulation by replacing standard button-press responses with mouse-tracking responses and examining both standard geometric measures of uncertainty as well as newer information-theoretic measures that separate fast from slow mouse movements. We found that when our analyses were restricted to end-state responses, tones and speech contexts appeared to produce similar effects. However, a more detailed time-course analysis revealed systematic differences between speech and tone contexts such that listeners' responses to speech contexts, but not to tone contexts, changed across the experimental session. Analyses of the time course of effects within trials using mouse tracking indicated that speech contexts elicited fewer x-position flips but more area under the curve (AUC) and maximum deviation (MD), and they did so in the slower portions of mouse-tracking movements. Our results indicate critical differences between the time course of speech and nonspeech context effects and that general auditory explanations, motivated by their apparent similarity, be reexamined.

    Lalonde, Carole

    2010-04-01

    The objective of this paper is to highlight the dimensions characterising the socialisation process in a crisis context. Based on the definition of organisational socialisation advanced by Van Maanen and Schein (1979) and employed later by Jones (1986), a crisis is presented as a passage from a 'normal' situation to an 'exceptional' situation. A crisis represents a socialisation context in the sense that it is a novel state in which actors must develop a different way of mobilising their knowledge, utilising their skills, and practicing their trade or profession. The paper discusses certain findings that have emerged from the literature on organisational socialisation, as well as from the testimony of actors who participated in efforts to manage the Quebec ice-storm crisis of early 1998. It is hoped that this exploratory study's data will give rise to fruitful interaction between the field of organisational socialisation and that of crisis management.

The first method is a straightforward 2-stage regression approach analogous to 2-stage least squares commonly used for IV analysis in linear regression....... The IV approach is very well developed in the context of linear regression and also for certain generalized linear models with a nonlinear link function. However, IV methods are not as well developed for regression analysis with a censored survival outcome. In this article, we develop the IV approach....... In this approach, the fitted value from a first-stage regression of the exposure on the IV is entered in place of the exposure in the second-stage hazard model to recover a valid estimate of the treatment effect of interest. The second method is a so-called control function approach, which entails adding...

    Full Text Available In this article, the established objective is to identify the relationship between socio demographic variables and materialism of the construct in the context of luxury consumer segment. To measure materialism used the theoretical model Richins (2004, tested and adapted nationally by Ponchio and Spider (2007. Through a quantitative survey of 320 consumers in São Paulo, we tested the relationship between the variables revealing results were compared to previous studies on the difference between the sociodemographic contexts. In conclusion, it can be seen that the luxury segment responds differently to the previous study. And unlike materialism identified himself only for the age group of 18 and 29, in relation to the other. The variables gender and financial income showed no distinction between established categories.

    2015-04-01

    We present the study of a wreck, in a foreshore area, in the North of Brittany, France, using two different digitization methods, photogrammetry and laser scanning. The digitization process had to deal with the tide constraints. The 3D data produced using these technologies has been deployed in a large immersive infrastructure dedicated to virtual reality research, in order to propose new practises for archaeologists. The overall purpose of our research project is to define an innovative and efficient methodology for the study and preservation of cultural heritage in an inter-tidal context. In the inter-tidal context, heritage is really fragile and the risk of destruction is real (storms, erosion, coastal development...). The traditional methods are no longer efficient. This paper describes preliminary results, through the joint work of a research institute specialized in underwater archaeology, a research laboratory of archaeology and archaeosciences, and a research laboratory in computer science.

    2016-01-01

    Alcohol use and misuse account for 3.3 million deaths every year, or 6 percent of all deaths worldwide. The harmful effects of alcohol misuse are far reaching and range from individual health risks, morbidity, and mortality to consequences for family, friends, and the larger society. This article reviews a few of the cultural and social influences on alcohol use and places individual alcohol use within the contexts and environments where people live and interact. It includes a discussion of macrolevel factors, such as advertising and marketing, immigration and discrimination factors, and how neighborhoods, families, and peers influence alcohol use. Specifically, the article describes how social and cultural contexts influence alcohol use/misuse and then explores future directions for alcohol research. PMID:27159810

    Full Text Available Service-Oriented Computing delivers the promise of configuring and reconfiguring software systems to address user's needs in a dynamic way. Context-aware computing promises to capture the user's needs and hence the requirements they have on systems. The marriage of both can deliver ad-hoc software solutions relevant to the user in the most current fashion. However, here it is a key to gather information on the users' activity (that is what they are doing. Traditionally any context sensing was conducted with hardware sensors. However, software can also play the same role and in some situations will be more useful to sense the activity of the user. Furthermore they can make use of the fact that Service-oriented systems exchange information through standard protocols. In this paper we discuss our proposed approach to sense the activity of the user making use of software.

  9. Some thoughts on power: International context

    Directory of Open Access Journals (Sweden)

    Josifidis Kosta

    2014-01-01

    Full Text Available This is a polemical essay that enters into broad dialogue with the contemporary literature concerning the dynamic of power. It refers to the appropriate material and results from the research of different theories. It proposes the constitutive position of the power in the international situation. In contrast to some current theories, we emphasize the importance of the politicoeconomical approach, denoting that only the methodology based on the logics of political economy can explain the dynamics of power in the international context. The main thread of this essay is that the international constellation is not a neutral environment, but a framework that is deeply determined by the power-relations. The central idea is that these relations should be explicated by the complex relationships between freedom and order. We analyze the interaction between the politics and economy as the constitutive feature of the structure of international context. This essay is divided into three sections. First, we are treating the meaning of order in an international context, in respect to the political-economic aspects of late capitalism. The notion of this order has a great importance in the economic reflections. The dynamic of the interconnectedness of global capitalism is examined considering the systematic aspects of power. After that we are analyzing different, and selected, aspects of the international sphere including: the spatiality of the world order, that is, the spatial aspects of the international dynamics in the context of globalization, the convergence or divergence between the capitalist and territorial logic, the “legaleconomic nexus” in international “chain”, the processes of the modification of the forms of competition within recent globalization, and the political-economic conflicts in relation to the regime of economic measurement. Starting with these considerations we explain the current debates on “demondialization”, or the

    Full Text Available Term Croatian is considered in Russian context, i. e. context of Russian scientific material (which is comparable to the unwritten situation in universities. Russian scientific texts connect term Croatian, almost without an exception, with the term Serbian in words such as Serbo-Croatian. This point of view is politically approved in the period untill 1990’s, but it exists in the 21st century’s scientific material. The nature of the problem lays, at the same time, in politics, language and society; thus, the question is: what is the reason of such a context in which Croatian language is placed now? There are no arguments for it, especially if it is for Slovak language politically based and language approved to be an entity – in comparison to the Czech language; for Ukrainian (once Littlerussian – at least in principle, in comparison to the Russian, or, more convincable, Belorussian to Russian (the standard Belorussian language exists from 1905. The term Croatian is independently, even in new books, connected with terms of soil, state, nation, but not language. And though today, because of political reasons, exists an awareness of Croatian language without its Serbian mirror reflexion, the term Serbo-Croatian stays. Thus, this paper looks through the history concerning Croatian language in 19, 20 and 21st century’s Russian philology, including Juraj Križanić and Vatroslav Jagić – innovators of the Croatian word in Russia.

  20. Context-Aware Generative Adversarial Privacy

    2017-12-01

    Full Text Available Preserving the utility of published datasets while simultaneously providing provable privacy guarantees is a well-known challenge. On the one hand, context-free privacy solutions, such as differential privacy, provide strong privacy guarantees, but often lead to a significant reduction in utility. On the other hand, context-aware privacy solutions, such as information theoretic privacy, achieve an improved privacy-utility tradeoff, but assume that the data holder has access to dataset statistics. We circumvent these limitations by introducing a novel context-aware privacy framework called generative adversarial privacy (GAP. GAP leverages recent advancements in generative adversarial networks (GANs to allow the data holder to learn privatization schemes from the dataset itself. Under GAP, learning the privacy mechanism is formulated as a constrained minimax game between two players: a privatizer that sanitizes the dataset in a way that limits the risk of inference attacks on the individuals’ private variables, and an adversary that tries to infer the private variables from the sanitized dataset. To evaluate GAP’s performance, we investigate two simple (yet canonical statistical dataset models: (a the binary data model; and (b the binary Gaussian mixture model. For both models, we derive game-theoretically optimal minimax privacy mechanisms, and show that the privacy mechanisms learned from data (in a generative adversarial fashion match the theoretically optimal ones. This demonstrates that our framework can be easily applied in practice, even in the absence of dataset statistics.

    2018-06-01

    School-based interventions for increasing physical activity among children are widespread, however there is still a lack of knowledge about how school context factors are linked to implementation quality and effectiveness of programmes. The aim of this paper is to examine teacher-perceived effectiveness of a Danish national classroom-based health programme 'Active Around Denmark' and in particular, to investigate whether perceptions vary as a function of school social context factors. After completion of the programme all teachers (N = 5.892) received an electronic questionnaire. 2.097 completed the questionnaire (response rate 36%) and 1.781 datasets could be used for analysis. The teachers were asked about their perceptions of changes in children's attitudes towards and levels of physical activity after the competition. Our results indicated that certain contextual factors, such as schools' prioritization of health promotion, teachers' support by their school principal in implementation as well as teacher's satisfaction with the school' physical environment made a significant difference in teacher-perceived effectiveness. To conclude, teacher-perceived effectiveness of the health programme does vary as a function of school social context factors.

    Full Text Available Objective: The objective of this paper is to identify differences between measurement of organisational entrepreneurship in for-profit and non-profit context and to propose the measures aligned to non-profit organisations. The main research question is whether the scales designed to measure entrepreneurial orientation can be used in non-profit organisations and under which conditions. Research Design & Methods: Research methodology is based on review of research tools and measurement scales related to organisational entrepreneurship and comparison of for-profit and non-profit organisations, as well as their characteristics in the context of entrepreneurial orientation. Findings: Entrepreneurial orientation can be measured in non-profit organisations using existing scales that have been designed for business organisations, however they have to be modified, mostly in the dimension of competitive aggressiveness and autonomy. Additionally, the scale should be enriched with items related to cooperation with other organisations. Implications & Recommendations: It is necessary to develop methods and tools that enable the measurement of entrepreneurial orientation in non-profit organisation as well as comparative research on entrepreneurial orientation in for-profit and non-profit organisations. Contribution & Value Added: The originality of this work lies in studying some aspects of entrepreneurial orientation, that apply to the social context. Some suggestions were formulated relating to the utilisation of entrepreneurial orientation scales (originally designed for business enterprises in non-profit organisations.

    The LPC (Laboratoire de Physique Corpusculaire) dedicated the major part of its 50 years activity to the Physics of Heavy Ions research conducted at GANIL. The activity in last two years on which this report is focused refers to this domain. Of special priority was the topics of hot and /or compressed nuclear matter aiming at understanding the physics of multifragmentation.The new ionization chambers INDRA and development of control programming required special efforts. A second direction of activity was the study of exotic nuclei particularly of halo nuclei. Specific equipment like the multi-detectors of DEMON and TAPS were designed for approaching the hot nuclei. Projects based on SPIRAL beams and collaborations dedicated to investigation of different new branches of exotic radioactivity ({beta}, xn: TONNERRE project) or mechanisms of induced fusion by radioactive nuclei to produce superheavy nuclei are reported on. The LPC was implied also in two important research programs, PRACEN and GEDEON (treatment of radioactive wastes) which made clear the evolution of research for the next two years: the correct understanding of the mechanisms of light particle production in neutron induced collisions at 20 to 200 MeV. In the frame of NEMO Collaboration that approaches topics related to the weak interactions the Laboratory has developed and tested the trigger system of NEMO3. A program utilizing ion trapping on SPIRAL for efficient studies on {beta}-neutrino angular correlations in superallowed decays will be thus feasible. Contracts like COGEMA and DAMRI oriented toward applied research are also mentioned

    This report presents the activity of `Laboratoire de Physique Corpusculaire` of Caen from July 1993 to June 1995. From its inception, at GANIL the nuclear physicists aimed at creating far off-equilibrium nuclear systems in order to obtain a better understanding of their properties as well as of nuclear matter. The first direction of research was the study of the excited nuclear matter i.e. the way in which the energy of heavy ion collisions is deposed in the compound system and nuclear fragments and the corresponding channels of their de-excitation. By means of NAUTILUS data and from comparisons of data with simulations it is now possible to measure life-times (down to 10{sup -22} s), the nuclear flow and the form of fragment emitters. These methods will be extensively used in the analysis of data taken with INDRA, which already has made evident a vaporization threshold. A second direction of research is based on the possibility to produce by fragmentation nuclei with a very anomalous neutron and proton composition. LISE, SISSI, and SPIRAL are used to re-accelerate the exotic or radioactive ions. By utilisation of DEMON the neutron halos of several nuclei has been studied, among which the one-neutron halo in {sup 19}C. The laboratory has participated also in large collaborations (NEMO) which investigated the neutrino nature and its rest mass which are important problems related to the validity of the particle physics standard model and, in turn, to the problem of the dark matter of the universe. A significant effort was attached to the realization of the utilized detectors and associated electronics. A special neutron detector was conceived and certified for COGEMA. The help of other institutions among which IN2P3, an CNRS institute, is acknowledged. There financial support as well as that obtained through ISMRA and the university has permitted the fruitful integration of LPC Caen in large national and international collaborations

    The LPC (Laboratoire de Physique Corpusculaire) dedicated the major part of its 50 years activity to the Physics of Heavy Ions research conducted at GANIL. The activity in last two years on which this report is focused refers to this domain. Of special priority was the topics of hot and /or compressed nuclear matter aiming at understanding the physics of multifragmentation.The new ionization chambers INDRA and development of control programming required special efforts. A second direction of activity was the study of exotic nuclei particularly of halo nuclei. Specific equipment like the multi-detectors of DEMON and TAPS were designed for approaching the hot nuclei. Projects based on SPIRAL beams and collaborations dedicated to investigation of different new branches of exotic radioactivity ({beta}, xn: TONNERRE project) or mechanisms of induced fusion by radioactive nuclei to produce superheavy nuclei are reported on. The LPC was implied also in two important research programs, PRACEN and GEDEON (treatment of radioactive wastes) which made clear the evolution of research for the next two years: the correct understanding of the mechanisms of light particle production in neutron induced collisions at 20 to 200 MeV. In the frame of NEMO Collaboration that approaches topics related to the weak interactions the Laboratory has developed and tested the trigger system of NEMO3. A program utilizing ion trapping on SPIRAL for efficient studies on {beta}-neutrino angular correlations in superallowed decays will be thus feasible. Contracts like COGEMA and DAMRI oriented toward applied research are also mentioned

  1. Using context to improve protein domain identification

    Directory of Open Access Journals (Sweden)

    Llinás Manuel

    2011-03-01

    Full Text Available Abstract Background Identifying domains in protein sequences is an important step in protein structural and functional annotation. Existing domain recognition methods typically evaluate each domain prediction independently of the rest. However, the majority of proteins are multidomain, and pairwise domain co-occurrences are highly specific and non-transitive. Results Here, we demonstrate how to exploit domain co-occurrence to boost weak domain predictions that appear in previously observed combinations, while penalizing higher confidence domains if such combinations have never been observed. Our framework, Domain Prediction Using Context (dPUC, incorporates pairwise "context" scores between domains, along with traditional domain scores and thresholds, and improves domain prediction across a variety of organisms from bacteria to protozoa and metazoa. Among the genomes we tested, dPUC is most successful at improving predictions for the poorly-annotated malaria parasite Plasmodium falciparum, for which over 38% of the genome is currently unannotated. Our approach enables high-confidence annotations in this organism and the identification of orthologs to many core machinery proteins conserved in all eukaryotes, including those involved in ribosomal assembly and other RNA processing events, which surprisingly had not been previously known. Conclusions Overall, our results demonstrate that this new context-based approach will provide significant improvements in domain and function prediction, especially for poorly understood genomes for which the need for additional annotations is greatest.

  2. Guest editor's introduction: Energy homeostasis in context.

    Science.gov (United States)

    Schneider, Jill E

    2014-06-01

    This article is part of a Special Issue "Energy Balance". Energy homeostasis is achieved through neuroendocrine and metabolic control of energy intake, storage, and expenditure. Traditionally, these controls have been studied in an unrealistic and narrow context. The appetite for food, for example, is most often assumed to be independent of other motivations, such as sexual desire, fearfulness, and competition. Furthermore, our understanding of all aspects of energy homeostasis is based on studying males of only a few species. The baseline control subjects are most often housed in enclosed spaces, with continuous, unlimited access to food. In the last century, this approach has generated useful information, but all the while, the global prevalence of obesity has increased and remains at unprecedented levels (Ogden et al., 2013, 2014). It is likely, however, that the mechanisms that control ingestive behavior were molded by evolutionary forces, and that few, if any vertebrate species evolved in the presence of a limitless food supply, in an enclosed 0.5 × 1 ft space, and exposed to a constant ambient temperature of 22+2 °C. This special issue of Hormones and Behavior therefore contains 9 review articles and 7 data articles that consider energy homeostasis within the context of other motivations and physiological processes, such as early development, sexual differentiation, sexual motivation, reproduction, seasonality, hibernation, and migration. Each article is focused on a different species or on a set of species, and most vertebrate classes are represented. Energy homeostasis is viewed in the context of the selection pressures that simultaneously molded multiple aspects of energy intake, storage, and expenditure. This approach yields surprising conclusions regarding the function of those traits and their underlying neuroendocrine mechanisms. Copyright © 2014. Published by Elsevier Inc.

    2012-01-01

    Little research focuses on the ways that bereaved family members react to and make meaning of their experience of the death of an elderly father and husband. In a qualitative, ethnographic study of 34 bereaved families we examined how family members respond to two inter-related social contexts: 1. Social-cultural values and attitudes such as attitudes toward grieving for old persons, and 2. The inter-personal dyadic relationship between interviewer and interviewee. An underlying theme of uncertainty pervades the study participants’ views of what is normal and expected in their own process of bereavement. Implications for future bereavement research are suggested. PMID:22939542

  7. Mapping Concepts of Agency in Educational Contexts.

    Matusov, Eugene; von Duyke, Katherine; Kayumova, Shakhnoza

    2016-09-01

    The purpose of this conceptual paper is to explore and map the "espoused theories" (Argyris and Schön 1978) of agency used in educational contexts. More precisely, we limit the focus on the normative view of student agency assumed within dominant school practices, desired by educational practitioners, leaving out non-normative emerging agencies such as student agency of resistance. Agency is a "tricky" concept, and often scholars who use the concept of agency do not define or operationalize it (e.g., Archer 2000). One reason is that there is no consensus among scholars about the notion of agency, especially when applied to educational contexts (Hitlin and Elder Sociological Theory, 25 (2), 170-191, 2007). Moreover, the recent neoliberal framing of individuals' agency as fully autonomous, flexible, and self-entrepreneur is adding the dilemma of agency manipulation in the sphere of education (Gershon 2011; Sidorkin 2004). To tackle this dilemma in educational contexts, we suggest to further interrogating the normative notion of agency in all its modes and develop a more nuanced conceptualization. We hope that such conceptualization would produce an understanding of the diverse manifestations and definitions of agency within a human ideal, educational content, behaviors, and social settings. We observed diverse uses of the normative term "agency" in educational discourse. We examined the term as used by researchers and practitioners. We also looked at the different ways it has been used in philosophical discussions of education, political framing of the civic role of schooling, disciplinary policy statements, school mission statements, and in everyday common use. It is worthy to note that our categorization of the use and meaning of the normative term "agency" depends on the scholars' epistemological paradigmatic assumptions, socio-political and historical situatedness, and ontological projects being translated into diverse scholarships of education. As a result of

  17. Political, religious and occupational identities in context: placing identity status paradigm in context.

    Science.gov (United States)

    Solomontos-Kountouri, Olga; Hurry, Jane

    2008-04-01

    This study critically contrasts global identity with domain-specific identities (political, religious and occupational) and considers context and gender as integral parts of identity. In a cross-sectional survey, 1038 Greek Cypriot adolescents (449 boys and 589 girls, mean age 16.8) from the three different types of secondary schools (state, state technical and private) and from different SES completed part of the Extended Objective Measure of Ego Identity Status-2 (EOMEIS-2). The macro-context of Greek Cypriot society is used to understand the role of context in adolescents' identities. Results showed that Greek Cypriot young people were not in the same statuses across their global, political, religious and occupational identities. This heterogeneity in the status of global identity and of each identity domain is partially explained by differences in gender, type of school and SES (socio-economic status). The fact that identity status is found to be reactive to context suggests that developmental stage models of identity status should place greater emphasis on context.

This contribution was directed by socio-educational research processes generated at the National University of Costa Rica (UNA, in the Center for Research and Teaching in Education (CIDE. The issue of health is part of the institutional plan and the Center. Whereas health, like education, is a fundamental human right that deserves responsibilities from pedagogy as educational science research, which analyzes and transforms. Therefore, it is urgent, in the face of new global challenges to address planetary crises linked to health. This research is based on the naturalistic paradigm and a methodology that assumes a type of joint research, where using a semi-structured interview achieves a deeper analysis that allows contrasting perceptions, theories and practices by comparing qualitative and quantitative data. From the results of impact the concept of Healthy Pedagogy is unknown in the university context. The connection between education and health as a holistic theoretical, epistemological and axiological construction, it includes the complexity theory that allows the university to take challenges with an enormous potential; promoting environments, styles and healthy organizations from healthy academic administrations from both individual and collective aspects. It is possible to construct new sense of orders, which assume in a responsible manner to re-dignify the university life in its various spaces and dimensions. Research has the valuable potential to become a dynamic element of institutional policies in favor of life.

  19. Medical jurisprudence in the local context.

    Medical jurisprudence in the local context would require the examination of a wide area. This paper focuses on liability producing conduct arising from the providing of medical services, other than liability for criminal negligent conduct. It examines the circumstances in which the physician-patient relationship emerges, in medical jurisprudence as against practice by medical practitioners. Tort law is the dominant legal theory, and reference is made to some intentional and miscellaneous torts. Implied contracts creating the relationship are touched upon, besides the reference to vicarious liability. Insanity and diminished responsibility in the criminal law, particularly the issue of whether the status quo is satisfactory and reliance on medical reports for purposes of treatment under drug laws are examined. Where abortion is performed, the question whether the husband has any right to prevent his wife from having a lawful abortion is discussed in the local context. Some thoughts on the medical (therapy, education and research) Act 1972 are expressed in relation to the living body, the corpse and the parts of the human body. The patient's right to determination and information in the light of the above legislation is also discussed.

  20. Empirical ethics, context-sensitivity, and contextualism.

    2005-10-01

    In medical ethics, business ethics, and some branches of political philosophy (multi-culturalism, issues of just allocation, and equitable distribution) the literature increasingly combines insights from ethics and the social sciences. Some authors in medical ethics even speak of a new phase in the history of ethics, hailing "empirical ethics" as a logical next step in the development of practical ethics after the turn to "applied ethics." The name empirical ethics is ill-chosen because of its associations with "descriptive ethics." Unlike descriptive ethics, however, empirical ethics aims to be both descriptive and normative. The first question on which I focus is what kind of empirical research is used by empirical ethics and for which purposes. I argue that the ultimate aim of all empirical ethics is to improve the context-sensitivity of ethics. The second question is whether empirical ethics is essentially connected with specific positions in meta-ethics. I show that in some kinds of meta-ethical theories, which I categorize as broad contextualist theories, there is an intrinsic need for connecting normative ethics with empirical social research. But context-sensitivity is a goal that can be aimed for from any meta-ethical position.

  1. LED Context Lighting System in Residential Areas

    Full Text Available As issues of environment and energy draw keen interest around the globe due to such problems as global warming and the energy crisis, LED with high optical efficiency is brought to the fore as the next generation lighting. In addition, as the national income level gets higher and life expectancy is extended, interest in the enhancement of life quality is increasing. Accordingly, the trend of lightings is changing from mere adjustment of light intensity to system lighting in order to enhance the quality of one’s life as well as reduce energy consumption. Thus, this study aims to design LED context lighting system that automatically recognizes the location and acts of a user in residential areas and creates an appropriate lighting environment. The proposed system designed in this study includes three types of processing: first, the creation of a lighting environment index suitable for the user’s surroundings and lighting control scenarios and second, it measures and analyzes the optical characteristics that change depending on the dimming control of lighting and applies them to the index. Lastly, it adopts PIR, piezoelectric, and power sensor to grasp the location and acts of the user and create a lighting environment suitable for the current context.

  2. Communication skills in context: trends and perspectives.

    Doctor-patient communication has been well researched. Less is known about the educational background of communication skills training. Do we aim for optimal performance of skills, or rather attempt to help students become skilled communicators? An overview is given of the current view on optimal doctor-patient communication. Next we focus on recent literature on how people acquire skills. These two topics are integrated in the next chapter, in which we discuss the optimal training conditions. A longitudinal training design has more lasting results than incidental training. Assessment must be in line with the intended learning outcomes. For transfer, doctor-patient communication must be addressed in all stages of health professions training. Elementary insights from medical education are far from realised in many medical schools. Doctor-patient communication would benefit strongly from more continuity in training and imbedding in the daily working contexts of doctors. When an educational continuum is realised and attention for doctor-patient communication is embedded in the working context of doctors in training the benefits will be strong. Training is only a part of the solution. In view of the current dissatisfaction with doctor-patient communication a change in attitude of course directors is strongly called for.

  3. Intergenerational Transmission in a Bidirectional Context

    Directory of Open Access Journals (Sweden)

    Jan De Mol

    2013-07-01

    Full Text Available Traditional approaches to the study of parent-child relationships view intergenerational transmission as a top-down phenomenon in which parents transfer their values, beliefs, and practices to their children. Furthermore, the focus of these unidirectional approaches regarding children's internalisation processes is on continuity or the transmission of similar values, beliefs, and practices from parents to children. Analogous unidirectional perspectives have also influenced the domain of family therapy. In this paper a cognitive-bidirectional and dialectical model of dynamics in parent-child relationships is discussed in which the focus is on continual creation of novel meanings and not just reproduction of old ones in the bidirectional transmission processes between parents and children. Parents and children are addressed as full and equally agents in their interdependent relationship, while these relational dynamics are embedded within culture. This cultural context complicates bidirectional transmission influences in the parent-child relationship as both parents and children are influenced by many other contexts. Further, current research in the domain of parent-child relationships and current concepts of intergenerational transmission in family therapy are reviewed from a bidirectional cognitive-dialectical perspective.

  4. Context-Aware Online Commercial Intention Detection

    Hu, Derek Hao; Shen, Dou; Sun, Jian-Tao; Yang, Qiang; Chen, Zheng

    With more and more commercial activities moving onto the Internet, people tend to purchase what they need through Internet or conduct some online research before the actual transactions happen. For many Web users, their online commercial activities start from submitting a search query to search engines. Just like the common Web search queries, the queries with commercial intention are usually very short. Recognizing the queries with commercial intention against the common queries will help search engines provide proper search results and advertisements, help Web users obtain the right information they desire and help the advertisers benefit from the potential transactions. However, the intentions behind a query vary a lot for users with different background and interest. The intentions can even be different for the same user, when the query is issued in different contexts. In this paper, we present a new algorithm framework based on skip-chain conditional random field (SCCRF) for automatically classifying Web queries according to context-based online commercial intention. We analyze our algorithm performance both theoretically and empirically. Extensive experiments on several real search engine log datasets show that our algorithm can improve more than 10% on F1 score than previous algorithms on commercial intention detection.

  5. Spatio-Temporal Reasoning and Context Awareness

    Science.gov (United States)

    Guesgen, Hans W.; Marsland, Stephen

    Smart homes provide many research challenges, but some of the most interesting ones are in dealing with data that monitors human behaviour and that is inherently both spatial and temporal in nature. This means that context becomes all important: a person lying down in front of the fireplace could be perfectly normal behaviour if it was cold and the fire was on, but otherwise it is unusual. In this example, the context can include temporal resolution on various scales (it is winter and therefore probably cold, it is not nighttime when the person would be expected to be in bed rather than the living room) as well as spatial (the person is lying in front of the fireplace) and extra information such as whether or not the fire is lit. It could also include information about how they reached their current situation: if they went from standing to lying very suddenly there would be rather more cause for concern than if they first knelt down and then lowered themselves onto the floor. Representing all of these different temporal and spatial aspects together is a major challenge for smart home research. In this chapter we will provide an overview of some of the methodologies that can be used to deal with these problems. We will also outline our own research agenda in the Massey University Smart Environments (MUSE) group.

  6. Sensitivity analysis in a structural reliability context

    Lemaitre, Paul

    2014-01-01

    This thesis' subject is sensitivity analysis in a structural reliability context. The general framework is the study of a deterministic numerical model that allows to reproduce a complex physical phenomenon. The aim of a reliability study is to estimate the failure probability of the system from the numerical model and the uncertainties of the inputs. In this context, the quantification of the impact of the uncertainty of each input parameter on the output might be of interest. This step is called sensitivity analysis. Many scientific works deal with this topic but not in the reliability scope. This thesis' aim is to test existing sensitivity analysis methods, and to propose more efficient original methods. A bibliographical step on sensitivity analysis on one hand and on the estimation of small failure probabilities on the other hand is first proposed. This step raises the need to develop appropriate techniques. Two variables ranking methods are then explored. The first one proposes to make use of binary classifiers (random forests). The second one measures the departure, at each step of a subset method, between each input original density and the density given the subset reached. A more general and original methodology reflecting the impact of the input density modification on the failure probability is then explored. The proposed methods are then applied on the CWNR case, which motivates this thesis. (author)

    A Virtual Field Trip project has been developed in collaboration with NASA Learning Technologies to allow students, internationally, to accompany scientists on a field trip to the Pilbara region of Western Australia to debate the relevance of ancient structures called stromatolites, to the origins of life on Earth and the search for life on Mars. The project was planned with the aim of exposing high school students to `science in the making', including exposure to the ongoing debate and uncertainties involved in scientific research. The development of the project stemmed from both research-based and anecdotal evidence that current science education programs are not providing secondary students with a good understanding of the processes of science. This study seeks to examine the effectiveness of student use of the tools to increase awareness of the processes of science and to evaluate the effectiveness of the tools in terms of student learning. The literature reports that there is a need for learning activities to be conducted within meaningful contexts. The virtual field trip tools create an environment that simulates key elements in the scientific process. Such an approach allows students to learn by doing, to work like scientists and apply their learning in an authentic context.

  8. Robust Visual Tracking via Exclusive Context Modeling

    KAUST Repository

    Zhang, Tianzhu

    2015-02-09

    In this paper, we formulate particle filter-based object tracking as an exclusive sparse learning problem that exploits contextual information. To achieve this goal, we propose the context-aware exclusive sparse tracker (CEST) to model particle appearances as linear combinations of dictionary templates that are updated dynamically. Learning the representation of each particle is formulated as an exclusive sparse representation problem, where the overall dictionary is composed of multiple {group} dictionaries that can contain contextual information. With context, CEST is less prone to tracker drift. Interestingly, we show that the popular L₁ tracker [1] is a special case of our CEST formulation. The proposed learning problem is efficiently solved using an accelerated proximal gradient method that yields a sequence of closed form updates. To make the tracker much faster, we reduce the number of learning problems to be solved by using the dual problem to quickly and systematically rank and prune particles in each frame. We test our CEST tracker on challenging benchmark sequences that involve heavy occlusion, drastic illumination changes, and large pose variations. Experimental results show that CEST consistently outperforms state-of-the-art trackers.

  9. Reimagining SSR in Contexts of Security Pluralism

    Full Text Available Within the repertoire of international stabilization interventions, security sector reform (SSR and other conventional efforts to strengthen security and governance institutions remain central. There is increasing recognition that the policies and practices operating under the rubric of SSR are blind to the empirical reality of 'security pluralism' in most stabilization contexts. In these contexts, both security providers directly authorized by the state (police, army and a multitude of other coercive actors engage in producing and reproducing order, and enjoy varying degrees of public authority and legitimacy. Recognizing this, research was undertaken in three cities (Beirut, Nairobi, and Tunis to discern the conditions enabling various security providers to forge constructive relations with local populations and governance actors. Drawing on insights generated by these case studies, this article problematizes conventional state-centric approaches and argues for a bold reimagining of SSR. It makes the case for an SSR approach that prioritizes promoting the accountability and responsiveness of all security providers, integrating efforts to strengthen the social determinants of security, and enabling a phased transition from relational to rules-based systems of security provision and governance.

    To conduct a concept analysis of clinical practice contexts (work environments) that facilitate or militate against the uptake of research evidence by healthcare professionals in clinical practice. This will involve developing a clear definition of context by describing its features, domains and defining characteristics. The context where clinical care is delivered influences that care. While research shows that context is important to knowledge translation (implementation), we lack conceptual clarity on what is context, which contextual factors probably modify the effect of knowledge translation interventions (and hence should be considered when designing interventions) and which contextual factors themselves could be targeted as part of a knowledge translation intervention (context modification). Concept analysis. The Walker and Avant concept analysis method, comprised of eight systematic steps, will be used: (1) concept selection; (2) determination of aims; (3) identification of uses of context; (4) determination of defining attributes of context; (5) identification/construction of a model case of context; (6) identification/construction of additional cases of context; (7) identification/construction of antecedents and consequences of context; and (8) definition of empirical referents of context. This study is funded by the Canadian Institutes of Health Research (January 2014). This study will result in a much needed framework of context for knowledge translation, which identifies specific elements that, if assessed and used to tailor knowledge translation activities, will result in increased research use by nurses and other healthcare professionals in clinical practice, ultimately leading to better patient care. © 2014 John Wiley & Sons Ltd.

  11. Context-dependent decay of motor memories during skill acquisition.

    Ingram, James N; Flanagan, J Randall; Wolpert, Daniel M

    2013-06-17

    Current models of motor learning posit that skill acquisition involves both the formation and decay of multiple motor memories that can be engaged in different contexts. Memory formation is assumed to be context dependent, so that errors most strongly update motor memories associated with the current context. In contrast, memory decay is assumed to be context independent, so that movement in any context leads to uniform decay across all contexts. We demonstrate that for both object manipulation and force-field adaptation, contrary to previous models, memory decay is highly context dependent. We show that the decay of memory associated with a given context is greatest for movements made in that context, with more distant contexts showing markedly reduced decay. Thus, both memory formation and decay are strongest for the current context. We propose that this apparently paradoxical organization provides a mechanism for optimizing performance. While memory decay tends to reduce force output, memory formation can correct for any errors that arise, allowing the motor system to regulate force output so as to both minimize errors and avoid unnecessary energy expenditure. The motor commands for any given context thus result from a balance between memory formation and decay, while memories for other contexts are preserved. Copyright © 2013 Elsevier Ltd.

    As we move from the oil-age to an energy infrastructure based on renewables, the need arises for new educational tools to support the analysis of geophysical phenomena and their behavior and properties. Our objective is to present models of these phenomena to make them amenable for incorporation into more comprehensive analysis contexts. Starting at the level of a college-level computer science course, the intent is to keep the models tractable and therefore practical for student use. Based on research performed via an open-source investigation managed by DARPA and funded by the Department of Interior [1], we have adapted a variety of physics-based environmental models for a computer-science curriculum. The original research described a semantic web architecture based on patterns and logical archetypal building-blocks (see figure) well suited for a comprehensive environmental modeling framework. The patterns span a range of features that cover specific land, atmospheric and aquatic domains intended for engineering modeling within a virtual environment. The modeling engine contained within the server relied on knowledge-based inferencing capable of supporting formal terminology (through NASA JPL's Semantic Web for Earth and Environmental Technology (SWEET) ontology and a domain-specific language) and levels of abstraction via integrated reasoning modules. One of the key goals of the research was to simplify models that were ordinarily computationally intensive to keep them lightweight enough for interactive or virtual environment contexts. The breadth of the elements incorporated is well-suited for learning as the trend toward ontologies and applying semantic information is vital for advancing an open knowledge infrastructure. As examples of modeling, we have covered such geophysics topics as fossil-fuel depletion, wind statistics, tidal analysis, and terrain modeling, among others. Techniques from the world of computer science will be necessary to promote efficient

  19. Context reinstatement and memory for intrinsic versus extrinsic context: the role of item generation at encoding or retrieval.

    Science.gov (United States)

    Nieznański, Marek

    2014-10-01

    According to many theoretical accounts, reinstating study context at the time of test creates optimal circumstances for item retrieval. The role of context reinstatement was tested in reference to context memory in several experiments. On the encoding phase, participants were presented with words printed in two different font colors (intrinsic context) or two different sides of the computer screen (extrinsic context). At test, the context was reinstated or changed and participants were asked to recognize words and recollect their study context. Moreover, a read-generate manipulation was introduced at encoding and retrieval, which was intended to influence the relative salience of item and context information. The results showed that context reinstatement had no effect on memory for extrinsic context but affected memory for intrinsic context when the item was generated at encoding and read at test. These results supported the hypothesis that context information is reconstructed at retrieval only when context was poorly encoded at study. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  1. Solving LR Conflicts Through Context Aware Scanning

    2011-09-01

    This paper presents a new algorithm to compute the exact list of tokens expected by any LR syntax analyzer at any point of the scanning process. The lexer can, at any time, compute the exact list of valid tokens to return only tokens in this set. In the case than more than one matching token is in the valid set, the lexer can resort to a nested LR parser to disambiguate. Allowing nested LR parsing requires some slight modifications when building the LR parsing tables. We also show how LR parsers can parse conflictive and inherently ambiguous languages using a combination of nested parsing and context aware scanning. These expanded lexical analyzers can be generated from high level specifications.

    Full Text Available The article focuses on the impact of various factors on the process of communication between military specialists and with the local civilians during peace support operations. The importance of religion, national and ethnic identities, military subculture, social status, and personal characteristics for achieving success or failure in interactions is underlined. Some differences between civil culture and military culture are disclosed and the need for cultural knowledge of the military members is stressed. The study is based on presenting and analysing situations of current intercultural interactions in Afghanistan, which deal with various problems that could be encountered by servicemen on a daily basis, i.e. body language differences, expression of friendly, unfriendly or indifferent attitude, typical reactions to gestures, common everyday topics for informal chats. Although the cultural interactions take place in present-day Afghanistan, the conclusions and suggestions are applicable to a much wider context of interacting between people with different cultural background.

    2013-07-01

    Full Text Available Various extensions of the temporal logic ATL have recently been introduced to express rich properties of multi-agent systems. Among these, ATLsc extends ATL with strategy contexts, while Strategy Logic has first-order quantification over strategies. There is a price to pay for the rich expressiveness of these logics: model-checking is non-elementary, and satisfiability is undecidable. We prove in this paper that satisfiability is decidable in several special cases. The most important one is when restricting to turn-based games. We prove that decidability also holds for concurrent games if the number of moves available to the agents is bounded. Finally, we prove that restricting strategy quantification to memoryless strategies brings back undecidability.

    Forenza, Brad; Eckert, Caitlin

    2018-01-01

    Social work is a broad field encompassing micro, mezzo, and macro areas of practice. Consequently, the field lacks a unifying professional identity due to the expansiveness of the profession. Professional identity is conceptualized as an extension of social identity, vis-à-vis the embodiment of three qualities: connectedness, expansiveness, and effectiveness. This study used 12 in-depth, individual interviews with practicing social workers to explore these qualities. Findings from interviews reveal six primary themes and 21 subthemes pertaining to social worker identity. Themes and subthemes are organized according to three broad families (social work in context, professional trajectories, and external influences). Implications for policy, practice, and future research are presented. © 2017 National Association of Social Workers.

    Full Text Available In this article, we address the reading issue from the point of view of complexity. Understanding, according to Beaugrande (1997, that the text is a communicative event whose configuration involves elements of different nature, including the participants of interaction, we think that traditional approaches to reading, even those which are focused on interaction, do not satisfactorily bolster comprehension of this phenomenon. In order to analyze how aspects that characterize reading as a complex activity show at (context comprehension in digital social media, we leaned on the articles by Pellanda (2005 and by Franco (2011 and we were supported by the autopoietic theory by Maturana and Varela (1995, as well as by the concepts of emergency and incorporation by Hanks (2008. Through the analysis of two examples of interaction conveyed in virtual environment, we observed that reading triggers readers’ autopoiesis as living systems.

    play a fundamental role in music perception. The mismatch negativity (MMN) is a brain response that offers a unique insight into these processes. The MMN is elicited by deviants in a series of repetitive sounds and reflects the perception of change in physical and abstract sound regularities. Therefore......, it is regarded as a prediction error signal and a neural correlate of the updating of predictive perceptual models. In music, the MMN has been particularly valuable for the assessment of musical expectations, learning and expertise.

    Social judgments are usually made in the context of complex information including verbal cues. Here we investigated the impact of verbal statements on social judgments by biasing male and female neutral faces with descriptives of differentially-valenced behaviour (criticizing or praising) targeting others or objects. Results showed significant main effects of valence and target, such that critical individuals were rated lower in likeability than praising ones and those targeting others relative to objects were valued less. In particular, those who criticized others were the most unlikeable. Among critical individuals, men were less likeable than women. Similarly, men became less valued while targeting others. Overall these findings suggest that the negative impact of critical attributes may trigger avoidance in social interaction while the positive impact of praise may trigger approach.

    2017-01-01

    Correlation filter (CF) based trackers have recently gained a lot of popularity due to their impressive performance on benchmark datasets, while maintaining high frame rates. A significant amount of recent research focuses on the incorporation of stronger features for a richer representation of the tracking target. However, this only helps to discriminate the target from background within a small neighborhood. In this paper, we present a framework that allows the explicit incorporation of global context within CF trackers. We reformulate the original optimization problem and provide a closed form solution for single and multi-dimensional features in the primal and dual domain. Extensive experiments demonstrate that this framework significantly improves the performance of many CF trackers with only a modest impact on frame rate.

    Full Text Available A growing body of research has shown the importance of music listening in psychological frameworks such as the construction of emotional and social identity. Nonetheless, the educational implications of this activity involve the way students use music listening for cultural development, cognitive processing and aesthetic reaction enhancement. The present study aims to review the relevant literature regarding how musical preference, a concept used mainly in music psychology, may be explored in educational contexts. Zajong’s (1968 theory of repeated exposure indicates that mere exposure to a stimulus is enough to create a favorable attitude towards it. This study investigates the experimental researches focused on the conditions where repeated exposure to academic music may generate the development of musical preference.

    Full Text Available Effective strategies in teacher education can be based on conceptual change and social constructivism models. From this framework theory, we assume that, in order to improve the succession of the different progressive stages of teachers'conceptual development, social and collaborative strategies are more adequate than individual methodologies. The main aim of this research is to analyze the use of particular and appropiate strategies in a constructivist and collaborative teacher education context. The case-study carried out proves that conceptual change is more effective when it is implemented synergistically with strategies directed towards group autonomy and group-regulation of learning rhythms and goals. The results demostrate the benefits derived from the use of strategies that propitiate the sharing and comparing practice among prospective teachers, especially, if they are, as usual, at heterogenous levels of teaching expertise.

    Mandrikas, Achilleas; Stavrou, Dimitrios; Skordoulis, Constantine

    2017-04-01

    This paper describes a teaching-learning sequence (TLS) about air pollution and the findings resulting from its implementation by pre-service elementary teachers (PET) currently undergraduate students of the Department of Primary Education in the National and Kapodistrian University of Athens, Greece. The TLS focused on the relation of air pollution with wind and topography in local conditions. An authentic context was provided to the students based on daily up-to-date meteorological data via the Internet in order to estimate air pollution. The results are encouraging given that PET can correlate wind and concentration of air pollutants through reading specialized angular diagrams and weather maps, can recognize the correlation of topography in the concentration of air pollutants, and can describe temperature inversion. However, the PET demonstrated clear difficulties in ability of orientation, in wind naming, and in interpretation of symbols on weather map. Finally, the implications on teaching air pollution are discussed.

  5. Social Context Disambiguates the Interpretation of Laughter

    2018-01-01

    Full Text Available Despite being a pan-cultural phenomenon, laughter is arguably the least understood behaviour deployed in social interaction. As well as being a response to humour, it has other important functions including promoting social affiliation, developing cooperation and regulating competitive behaviours. This multi-functional feature of laughter marks it as an adaptive behaviour central to facilitating social cohesion. However, it is not clear how laughter achieves this social cohesion. We consider two approaches to understanding how laughter facilitates social cohesion – the ‘representational’ approach and the ‘affect-induction’ approach. The representational approach suggests that laughter conveys information about the expresser’s emotional state, and the listener decodes this information to gain knowledge about the laugher’s felt state. The affect-induction approach views laughter as a tool to influence the affective state of listeners. We describe a modified version of the affect-induction approach, in which laughter is combined with additional factors – including social context, verbal information, other social signals and knowledge of the listener’s emotional state – to influence an interaction partner. This view asserts that laughter by itself is ambiguous: the same laughter may induce positive or negative affect in a listener, with the outcome determined by the combination of these additional factors. Here we describe two experiments exploring which of these approaches accurately describes laughter. Participants judged the genuineness of audio–video recordings of social interactions containing laughter. Unknown to the participants the recordings contained either the original laughter or replacement laughter from a different part of the interaction. When replacement laughter was matched for intensity, genuineness judgements were similar to judgements of the original unmodified recordings. When replacement laughter was not

  6. Understanding Female Receiver Psychology in Reproductive Contexts.

    Lynch, Kathleen S

    2017-10-01

    Mate choice decision-making requires four components: sensory, cognitive, motivation, and salience. During the breeding season, the neural mechanisms underlying these components act in concert to radically transform the way a female perceives the social cues around her as well as the way in which cognitive and motivational processes influence her decision to respond to courting males. The role of each of these four components in mate choice responses will be discussed here as well as the brain regions involved in regulating each component. These components are not independent, modular systems. Instead, they are dependent on one another. This review will discuss the many ways in which these components interact and affect one another. The interaction of these components, however, ultimately leads back to a few key neuromodulators that thread motivation, sensory, salience, and cognitive components into a set of inter-dependent processes. These neuromodulators are estrogens and catecholamines. This review will highlight the need to understand estrogens in reproductive contexts not just as simply a 'sexual motivation modulator' or catecholamines as 'cognitive regulators' but as neuromodulators that work together to fully transform a non-breeding female into a completely reproductive female displaying: heightened sexual interest in courting males, greater arousal and selective attention toward courtship signals, improved signal detection and discrimination abilities, enhanced contextual signal memory, and increased motivation to respond to signals assigned incentive salience. The aim of this review is to build a foundation in which to understand the brain regions associated with cognitive, sensory, motivational, and signal salience not as independently acting systems but as a set of interacting processes that function together in a context-appropriate manner. © The Author 2017.

    Tuberculosis (TB) nowadays still becomes one of the world’s deadliest communicable disease. More than half were in South-East Asia and Western Pacific Regions, including Indonesia. As developing country, Indonesia remains classic problems in overcoming TB, that is discontinuation on treatment. Most of discontinuation on treatment among TB patients are affected by diagnostic delay that caused by patient delay. These phenomena occur in many areas, rural to suburb, coastal to plantation, and so on, and they are related with social context among community that could be social capital for each community to deal with TB. Jember as one of county in East Java is known as plantation area. It also has a high prevalence of TB. This study focused on understanding about social context among community, especially on plantation area. This cross-sectional study involved in three districts of Jember, those are Tanggul, Pakusari, and Kalisat. The data were obtained directly from the TB patients, local community, and Primary Health Care (PHC) where the patients recorded. Spatial analysis and social network analysis (SNA) were applied to obtain health seeking behavior pattern among the TB patients coincide the community. Most of TB patients had already chosen health professionals to lead the treatment, although some of them remained to choose self-medication. Meanwhile, SNA showed that religious leader was considered as main part of countermeasures of TB. But they didn’t ever become central figures. So it can be concluded that there are other parts among community who can contribute due to combatting on TB.

  9. Metaphor in the ESP engineering context

    Full Text Available The explicit use of metaphor in the EFL classroom has been documented to enhance the communicative skills of learners (Cameron & Low, 1999; Cortazzi & Jin, 1999; Low, 1999; Littlemore & Low, 2006. ESP learners with a technical background, however, are not usually trained on the presence of metaphor in their knowledge field, or on its use. The aim of this paper is to analyze the unprompted use of metaphor in the verbal responses given by a group of Spanish civil engineering undergraduates when depicting visuals related to their area of expertise. The responses of the students were obtained from a questionnaire completed in the classroom which was later crosschecked with the answers given by a group of professional civil engineers. This was done to compare the occurrence of metaphor as a descriptive verbalizer in the academic and the professional contexts. The results confirm the use of general metaphor in both groups, and the use of field-specific metaphor particularly in the professional engineers (in order to avoid confusion with the engineer students group, which appears to suggest the evolving character of metaphor in the civil engineering discourse community. We conclude by highlighting the dynamicity of metaphor in the civil engineering context. From a pedagogic viewpoint, it would be advisable to concentrate on metaphor as a learning feature by considering three main dimensions: conceptual, linguistic and visual. This could be carried out by offering students corpora-driven examples of metaphor visibility in the different civil engineering genres, addressing non-verbal elements, such as sketches, drawings, designs and pictures where metaphor may be used. The theoretical framework for this study draws from conceptual metaphor theory and conceptual integration theory combined with a multimodal approach to metaphor (Fauconnier & Turner, 2002; Deignan, 2005; Steen, 2007; Fauconnier & Turner, 2008, Forceville, 2010; Kress, 2010.

Several monitoring techniques have been proposed in the past to track users’ behaviour; however, these approaches are either subjective and prone to misreporting, such as questionnaires, or only focus on a specific component of context, such as activity counters. This work presents an innovative multimodal context mining framework to inspect and infer human behaviour in a more holistic fashion. The proposed approach extends beyond the state-of-the-art, since it not only explores a sole type of context, but also combines diverse levels of context in an integral manner. Namely, low-level contexts, including activities, emotions and locations, are identified from heterogeneous sensory data through machine learning techniques. Low-level contexts are combined using ontological mechanisms to derive a more abstract representation of the user’s context, here referred to as high-level context. An initial implementation of the proposed framework supporting real-time context identification is also presented. The developed system is evaluated for various realistic scenarios making use of a novel multimodal context open dataset and data on-the-go, demonstrating prominent context-aware capabilities at both low and high levels.

  9. The effect of normative context variability on recognition memory.

    Steyvers, Mark; Malmberg, Kenneth J

    2003-09-01

    According to some theories of recognition memory (e.g., S. Dennis & M. S. Humphreys, 2001), the number of different contexts in which words appear determines how memorable individual occurrences of words will be: A word that occurs in a small number of different contexts should be better recognized than a word that appears in a larger number of different contexts. To empirically test this prediction, a normative measure is developed, referred to here as context variability, that estimates the number of different contexts in which words appear in everyday life. These findings confirm the prediction that words low in context variability are better recognized (on average) than words that are high in context variability. (c) 2003 APA, all rights reserved

  10. Transformative Pedagogy in Context: being and becoming

    Full Text Available This paper examines an original construct, ‘‘transformative pedagogy’’, in the context of post-primary teacher education in Ireland. The construct is examined from philosophical and psychological perspectives, and key distinctions are drawn between it and other pedagogies. Links are made, where appropriate, to research findings from a recent study carried out by the author in cooperation with teacher-educators and student-teachers in the context of pre-service teacher education at the National University of Ireland, Galway, Ireland. In addition, the paper refers to examples that illustrate some of the benefits that can be derived from school-society links. ‘‘Transformative pedagogy’’ creates conditions that support teacher and pupils (participants in developing their identity as whole persons who have a relationship based on interdependence. In essence, ‘‘transformative pedagogy’’ is about creating conditions that support participants in developing capacity as ‘‘beings-in-relation’’ as well as ‘‘beings-in-becoming’’. Key perspectives are used to frame the discussion: 1 identity, 2 beliefs and attitudes, 3 knowledge, 4 moral-ethical values, 5 socio-affective factors, 6 social interaction and collaboration, 7 critical reflection, 8 school and wider society. ‘‘Transformative pedagogy’’ is underpinned by moral-ethical values that support participants as ‘‘beings-in-relation’’ who are also ‘‘beings-in-becoming’’. Participants develop consciousness that is a prerequisite for constructing their own meanings as part of critiquing and shaping the world. The process implies committed action, informed by moral-ethical values, that is geared towards personal as well as social transformations. The construct suggests a need for a more integrated and trans-curricular approach to teaching and learning than has traditionally been the case in Ireland, and an approach that brings school life and wider

  11. Sociophonetics: The Role of Words, the Role of Context, and the Role of Words in Context.

    Hay, Jennifer

    2018-03-02

    This paper synthesizes a wide range of literature from sociolinguistics and cognitive psychology, to argue for a central role for the "word" as a vehicle of language variation and change. Three crucially interlinked strands of research are reviewed-the role of context in associative learning, the word-level storage of phonetic and contextual detail, and the phonetic consequences of skewed distributions of words across different contexts. I argue that the human capacity for associative learning, combined with attention to fine-phonetic detail at the level of the word, plays a significant role in predicting a range of subtle but systematically robust observed socioindexical patterns in speech production and perception.

    Full Text Available The monograph genre is a social action which organizes the academic culture at the conclusion stage of a Graduation and a Specialization university course, as well as it is a textual action laid out in written production. For this article, we select six copies of this genre, from Letters and Social Sciences courses, through a multiple case study, with a descriptive-interpretativist methodology, to analyze this genre and its recurring movements in your introduction section. Supported by sociorhetorical approaches, as Swales (1990; 2004 and Bhatia (2004; 2009, we investigate monographs in continuous with other initiation genres in the scientific domain. We  conclude that they reveal a prototypicality marked by more general movements, as identifying theme, object presentation, question and research objectives. In addition, for more specific movements, in the case of our data, such as the information searches are derived from projects developed in the institutional promotion programme for the training of researchers (PIBIC, adapting to the situational context and communicative that evokes.

  13. Systemic Lupus Erythematosus: Definitions, Contexts, Conflicts, Enigmas

    Science.gov (United States)

    Rekvig, Ole Petter

    2018-01-01

    Systemic lupus erythematosus (SLE) is an inadequately defined syndrome. Etiology and pathogenesis remain largely unknown. SLE is on the other hand a seminal syndrome that has challenged immunologists, biologists, genetics, and clinicians to solve its nature. The syndrome is characterized by multiple, etiologically unlinked manifestations. Unexpectedly, they seem to occur in different stochastically linked clusters, although single gene defects may promote a smaller spectrum of symptoms/criteria typical for SLE. There is no known inner coherence of parameters (criteria) making up the disease. These parameters are, nevertheless, implemented in The American College of Rheumatology (ACR) and The Systemic Lupus Collaborating Clinics (SLICC) criteria to classify SLE. Still, SLE is an abstraction since the ACR or SLICC criteria allow us to define hundreds of different clinical SLE phenotypes. This is a major point of the present discussion and uses “The anti-dsDNA antibody” as an example related to the problematic search for biomarkers for SLE. The following discussion will show how problematic this is: the disease is defined through non-coherent classification criteria, its complexity is recognized and accepted, its pathogenesis is plural and poorly understood. Therapy is focused on dominant symptoms or organ manifestations, and not on the syndrome itself. From basic scientific evidences, we can add substantial amount of data that are not sufficiently considered in clinical medicine, which may change the paradigms linked to what “The Anti-DNA antibody” is—and is not—in context of the imperfectly defined syndrome SLE.

  15. EMPLOYEES’ RIGHTS IN THE CORPORATE GOVERNANCE CONTEXT

    Directory of Open Access Journals (Sweden)

    Andrei Emil Moise

    2014-11-01

    Full Text Available The recent redrafting of the corporate governance legal frame at the European level, with emphasis on its functions of valorization and security of shareholders’ rights, maximizing profits and minimizing risks, raises the balance issue between the above stated goals and the necessity for compliance with employees’ rights. In this context, we intend to analyze the possibility for the labour regulations to be completed or substituted by the “soft-law” regulations, product of corporate governance, to identify the degree of stability, transparency and predictability of the employer-employee relationship and to identify the reconciliation methods between the apparently differing objectives of corporate governance and protection of employees’ rights. The study performs an analysis of the cases in which relevant provision form both corporate law and labour law are applicable, providing also practical examples from the real business environment, a comparative analysis of the relevant legal provisions from the principal EU member states and also an examination of the relevant doctrine. The research results indicate the negative effect of the poor implementation of the corporate governance rules over employees’ rights, but also the fact that compliance with employees’ rights can be and should be an instrument of the effective and transparent corporate governance rather than a barrier, providing several directions for improving the labour relations in the corporate environment.

  16. Community Context, Land Use and First Birth.

    Ghimire, Dirgha J; Axinn, William G

    2010-09-01

    This paper examines the influence of community context and land use on the monthly odds of first birth in a society in the midst of dramatic fertility transition. The theoretical framework guiding our work predicts that proximity to non-family services should delay first births by creating opportunities for competing non-family activities and spreading new ideas that change expectations about family life. On the other hand, living in agricultural settings that provide opportunities for higher returns to the child labor should speed first births. We use a longitudinal, multilevel, mixed-method data from the Nepalese Himalayas to test these predictions. The empirical results reveal that non-family services during childhood and during early adulthood both have important independent influences on the odds of first birth. Also, as predicted, a high density of agricultural land use affects the odds of first births in the opposite direction, speeding first births. This clear pattern of contrasting effects provides important new evidence of the contextual dynamics that produce watershed changes in post-marital birth timing.

    Full Text Available Business Strategy, as part adaptation of company’s actions in a particular business area to specific demand and competition or conversely opening new market positions, is the main strategic move that ensures competitiveness in the market and ensuring appreciable profitability of the business. Marketing policies adopted by one firm are fundamental decisions concerning the product and its conditioning elements. Marketing decisions are manifold; the most important for a company is selection of those marketing elements that can support business strategy as defined at the level of a whole company's strategic units. This paper brings to the fore just correlations between marketing actions that are at the reach of the company and strategic business contexts in which it may lie. Thus, according to the four strategic situation of the market, will analyze key sets of strategic action in the field of marketing that companies can use in order to support the business strategy and not undermine the production and marketing efforts with the costs involved.

    Full Text Available The present study investigated workplace incivility in a Swedish context. The first aim was to assess how common the phenomenon is and the second was to study which groups (gender, age, ethnicity, and power position are most targeted by workplace incivility and are more prone to act in an uncivil way. Additionally, the relationships between experienced and witnessed incivility and wellbeing as well as instigated incivility were investigated. An online survey was administered by SIFO (the national public opinion poll agency. The collected data consist of a stratified sample whose composition is identical to the working population in Sweden (N = 3001. The results show that almost three quarters of the respondents had been the target of coworker incivility and 52% of supervisor incivility at least one to two times in the past year. Of the respondents, 75% had witnessed coworkers and 58% witnessed a supervisor treating others in an uncivil way. Furthermore, 66% had instigated uncivil acts toward others. The results also show that female and younger employees are slightly more targeted by incivility from coworkers and younger employees and supervisors are slightly more prone to instigate incivility. Moreover, it was found that that experienced incivility was the strongest predictor of low well-being and that witnessed incivility was the strongest predictor of instigated incivility.

    Full Text Available Brands may be perceived as possessing a set of distinct traits or characteristics, i.e., a personality, similar to aperson. Thus, the personality of a brand is relevant as a source of differentiation in an increasingly competitivemarket environment. In this study, the authors explore the dimensions of brand personality proposed by J. Aaker(1997, seeking to discover the particular evaluation dimensions of the Brazilian context. The study wasconducted in exploratory stages, beginning with a preparatory stage that was carried out by professionals andacademics from the fields of communication and marketing. This was followed by stages of conclusive researchusing an online survey with a sample of 1,302 Brazilian consumers. Two sub-samples were extracted: onecalibration sample for exploratory factor analysis and a validation sample to perform confirmatory factoranalysis in order to verify the convergent and discriminant validities of the final scale. Five dimensions of brandpersonality in Brazil were detected: credibility, joy, audacity, sophistication and sensitivity. These dimensionsshowed some differences in comparison with similar studies that had been carried out in other countries. Thestudy led to a scale of 28 items for measuring brand personality and made it possible to compare competingbrands in terms of brand personality.

    Full Text Available This article presents the development of a research program on the teaching of chemistry guided by a theoretical framework of the Sociology of Education, and discusses its main results. Under a comparative analysis perspective, the pedagogical practices of teachers of chemistry teachers who teach in schools of different social contexts were been characterized by a set of indicators related to the rules of pedagogical discourse and were associated to the macrossocial issues of power and control, according to the theory by Basil Bernstein. The article presents the most relevant results obtained, highlighting the characteristics less favorable to the acquisition of scientific knowledge and skills, and which often constitute the practices observed in the schools where study the most needy students of the social spectrum. On the other hand, some results also show that, by altering some of these characteristics, teachers can increase student’s performance. These results have implications for the education of chemistry teachers and for public policies. The final part discusses the further unfolding and new directions for future research related to this program.

    Full Text Available Background. Mental health research appears to be continually transforming. Recent literature reflects a greater appreciation for the ways in which pathoplastic features of culture modulate emotional regulation. This article introduces those aspects of the literature which explore the (reconsideration of culture as a dynamic and essential construct in the clinical formulation of psychopathology. Objectives. The study aims to review literature that focuses on the dynamic influence of culture in psychopathology. Furthermore, the researchers aim to present a view on the ways in which culture appeared to shape the topography of psychopathology nosology. Method. A literature review of 31 sources. Results. The review indicated that 29 literature sources were conceptual in design, suggesting a great need for more empirical research. This section also explored themes identified during the literature review. The literature was tabulated according to features and emerging themes. Three major themes were identified and included: the cultural context; the evolving definitions of culture; and culture and psychopathology. Conclusion/discussion. An analysis of the themes was offered. The authors concluded by highlighting the significance of the literature at present. Areas of particular interest suggested that health and behaviour are dependent, at least in part, on culture; psychopathology may also be appreciated as a social construct; culture influences psychopathology regardless of the aetiology; diagnostic classes do not adequately consider operational definitions; and a greater focus on hermeneutic perceptivity in appreciating cultural dynamics in psychopathology will benefit clinical assessment.

    This study examined social capital development in three all-terrain vehicles (ATV) clubs in Maine using an adapted version of Lin's (2001) social capital theory model. The structural components of social capital identified included collective assets and individual assets in the form of normative behavior and trust relationships. Also identified were counter-norms for individual ATV riders identified as having divergent norms from club members. The second component of social capital is access to and mobilization of network contacts and resources. Access networks in the context of the ATV clubs studied were identified as community and landowner relations while mobilization of resources was existent in club membership attempts toward self-governance and efforts of the statewide "umbrella" organization. Instrumental outcomes benefit society and expressive outcomes benefit the individual. Both types of returns are present in the data suggesting that ATV clubs are creating social capital. This is important information to clubs who desire to market themselves, improve their reputations, and enhance their volunteer association. It is of further interest to state governments who fund clubs through trail grants as proof that a return on investment is being realized. Theoretical and applied implications for these and other types of recreation-based volunteer associations (e.g., clubs, friends groups, advocacy groups) are presented.

    This presentation discussed the particularities of the energy context of Nunavut. In Nunavut, diesel generators are the predominant source of heat and electricity. The territory completely relies on imported fossil fuels, which are shipped to the area during a short ice-free season and stored. Qulliq Energy Corporation is the exclusive supplier of electricity. There is no grid interconnection and only one operational wind turbine and one photovoltaic array. The primary focus of energy projects is energy efficiency with an emphasis on plant upgrades and residual heat. Wind, solar, tides and ocean currents, hydro, and waste are potential sources of energy in the North. Government policy seeks to develop a sustainable energy system that is secure, environmentally responsible, and economically optimal for Nunavummiut. This would improve security, reduce costs and environmental impacts, and generate business and employment. To this end, the government seeks to reduce reliance on imported fossil fuels and diversify the energy supply to include clean, renewable, domestic energy sources. Remoteness, the extreme climate, inadequate infrastructure, small grid sizes, human resource and technological limitations, and climate change impacts are among the challenges Nunavut faces in developing a sustainable energy system. 15 figs.

  6. "Death with dignity" in the Japanese context.

    Shimoda, Motomu

    2005-01-01

    In Japan, "death with dignity" is a widely known term that is distinguished from "euthanasia." It is generally defined as "the act of letting a terminally ill or a patient in a persistent vegetative state die by withdrawing life-sustaining treatment on request in the form of a living will." Most Japanese people consider death with dignity a desirable way of terminating one's life and it is therefore acceptable as a "natural death" or "humane death." Originally, death with dignity was regarded as a passive intervention, but since the 1990s, its connotations have changed in western countries; people claim that voluntary active euthanasia and physician-assisted suicide should be legalized as death with dignity or the "right to die." In this paper, I examine the points and problems of this new type of death with dignity and propose an alternative version of death with dignity especially for the Japanese context, i.e. the end-of-life care process in support of terminal living with dignity.

  7. Context-sensitive intra-class clustering

    KAUST Repository

    Yu, Yingwei

    2014-02-01

    This paper describes a new semi-supervised learning algorithm for intra-class clustering (ICC). ICC partitions each class into sub-classes in order to minimize overlap across clusters from different classes. This is achieved by allowing partitioning of a certain class to be assisted by data points from other classes in a context-dependent fashion. The result is that overlap across sub-classes (both within- and across class) is greatly reduced. ICC is particularly useful when combined with algorithms that assume that each class has a unimodal Gaussian distribution (e.g., Linear Discriminant Analysis (LDA), quadratic classifiers), an assumption that is not always true in many real-world situations. ICC can help partition non-Gaussian, multimodal distributions to overcome such a problem. In this sense, ICC works as a preprocessor. Experiments with our ICC algorithm on synthetic data sets and real-world data sets indicated that it can significantly improve the performance of LDA and quadratic classifiers. We expect our approach to be applicable to a broader class of pattern recognition problems where class-conditional densities are significantly non-Gaussian or multi-modal. © 2013 Elsevier Ltd.

    This paper summarizes the first assessment performed by the IRSN related to the management of French power water reactors (PWR) safety. The conclusions of this assessment were submitted to the 'advisory committee' in April 2008. After an introduction reminding the French industrial and regulatory context as well as the way the assessment has been conducted, the relationship between safety and competitiveness is briefly discussed. Then the main issues and recommendations pointed out by the IRSN assessment are presented. These concern in particular: the balance between the shift operation team and the outage project team; the real-time decision-making capabilities of plant managers; the lessons learnt from the analyses of decision-making processes; the management of cultural changes. Finally, a conclusion presents a global diagnosis in terms of strengths and weaknesses of the EDF safety management system and proposes some ideas regarding the 'priority given to safety', the meaning of safety used by operative people and the continuous improvement approach. Lastly, methodological lessons are pointed out. The slides of the presentation have been added at the end of the paper. (author)

    2013-06-01

    Full Text Available In this article we discuss three interrelated topics, framed within discourses of individual and collective human rights, right of self-determination, democratic processes, people`s uprisings, and geopolitical (imbalances. First, we are interested in the situation of Western Sahara and the 37 years of ongoing Moroccan occupation; we refer to this country as Africa’s last colony. Discussion leads us to reflection of the political strategies of Sahrawis to achieve their national liberation, one of them being Gdeim Izik camp, understood by some relevant authors as the beginning of the »Arab spring«. The »Arab spring« is the second focus of our discussion. We offer a timetable and stress the context of events from the Western Sahara attempt in Gdeim Izik, popular uprisings in Tunisia, Egypt and Yemen that ended in the resignations of their leaders and governments, civil wars in Syria and Libya, to bigger and smaller protests and their consequences in Oman, Kuwait, Bahrain, Jordan, Morocco, Mauretania, Algeria, Sudan, Saudi Arabia, Iraq, Lebanon and Djibouti. We try to offer a deconstruction and reconstruction of the »Arab spring«. In the third part, we discuss the Israeli/Palestinian conflict and the perspectives for solution. The conclusion reflects on the strategic, social and political implications of the »Arab spring«, the role and response of the international community, and the new global wave of resistance against political and financial elites.

    Full Text Available This article examines the relationships between workers’ control over their working time and their well-being, looking at how these relationships differ across a set of health care occupations that are stratified by class, gender, and race (physicians, nurses, emergency medical technicians [EMTs], and certified nursing assistants [CNAs]. Across occupations, workers’ ability to control their schedules decreases their job-related stress. The results show that different dimensions of worktime control (WTC affect workers in different occupations in distinctive ways, offering a corrective to prior work that combines workers who occupy different locations in the system of social stratification. Among nursing assistants—the most socially marginalized group in the study—the relationships between particular aspects of WTC and job stress were distinct from those associations among the other three occupations, reinforcing the importance of examining these relationships in occupationally specific contexts. This kind of comparative perspective illuminates the ways distributions of intangible resources such as WTC both emerge from and reinforce existing patterns of social stratification. The implications of these differences for research and policy are discussed.

    Full Text Available The conception of the pedagogical professional training has evolved alongside with the educative changes that have taken place in the history of Cuban education. This research was intended to examine the evolution of professional training from the foundation of colleges of Education to the present. The study takes into account the relation of the instructive, educative and developing aspects; the development of the professional needs and their influence on cognitive and formative activity of learners and their professional performance; the components of contents included in the evaluation of the professional competence; and the comprehensive disciplinary approach of the formation process. Thus, this investigation is aimed at providing a historical analysis of the development of the pedagogical professional training, illustrating the continuity of the formative process in Cuban context. This study revealed the main trends of the pedagogical professional training for the General Senior High Education, It shows the movement from a former segmentation of instructive and educative components and emotional and intellectual educations to a and interconnected approach of both processes.

    Hippocampal place cells respond heterogeneously to elemental changes of a compound spatial context, suggesting that they form a distributed code of context, whereby context information is shared across a population of neurons. The question arises as to what this distributed code might be useful for. The present study explored two possibilities: one, that it allows contexts with common elements to be disambiguated, and the other, that it allows a given context to be associated with more than one outcome. We used two naturalistic measures of context processing in rats, rearing and thigmotaxis (boundary-hugging), to explore how rats responded to contextual novelty and to relate this to the behavior of place cells. In experiment 1, rats showed dishabituation of rearing to a novel reconfiguration of familiar context elements, suggesting that they perceived the reconfiguration as novel, a behavior that parallels that of place cells in a similar situation. In experiment 2, rats were trained in a place preference task on an open-field arena. A change in the arena context triggered renewed thigmotaxis, and yet navigation continued unimpaired, indicating simultaneous representation of both the altered contextual and constant spatial cues. Place cells similarly exhibited a dual population of responses, consistent with the hypothesis that their activity underlies spatial behavior. Together, these experiments suggest that heterogeneous context encoding (or "partial remapping") by place cells may function to allow the flexible assignment of associations to contexts, a faculty that could be useful in episodic memory encoding.

  14. A fundamental role for context in instrumental learning and extinction.

    Science.gov (United States)

    Bouton, Mark E; Todd, Travis P

    2014-05-01

    The purpose of this article is to review recent research that has investigated the effects of context change on instrumental (operant) learning. The first part of the article discusses instrumental extinction, in which the strength of a reinforced instrumental behavior declines when reinforcers are withdrawn. The results suggest that extinction of either simple or discriminated operant behavior is relatively specific to the context in which it is learned: As in prior studies of Pavlovian extinction, ABA, ABC, and AAB renewal effects can all be observed. Further analysis supports the idea that the organism learns to refrain from making a specific response in a specific context, or in more formal terms, an inhibitory context-response association. The second part of the article then discusses research suggesting that the context also controls instrumental behavior before it is extinguished. Several experiments demonstrate that a context switch after either simple or discriminated operant training causes a decrement in the strength of the response. Over a range of conditions, the animal appears to learn a direct association between the context and the response. Under some conditions, it can also learn a hierarchical representation of context and the response-reinforcer relation. Extinction is still more context-specific than conditioning, as indicated by ABC and AAB renewal. Overall, the results establish that the context can play a significant role in both the acquisition and extinction of operant behavior. Copyright © 2014 Elsevier B.V. All rights reserved.

  15. Canada's climate change policy in context

    Climate change has a wide range of implications for the health, well-being, and economic prospects for Canadians, and for the ecological systems that sustain life on this planet. The overwhelming scientific opinion, world leaders and even a growing number of corporate leaders now agree that the Earth is undergoing a significant and unusual warming period as a result of the build-up of greenhouse gases in the atmosphere. There is also wide agreement that much of this build-up is anthropogenic, and that a global effort is required to slow this trend. Because climate change is a global problem, it requires global solutions by way of reduction in global greenhouse gas emissions. In this context, the Kyoto Agreement of 1997 constitutes a major breakthrough, even though it takes only a small step towards towards altering the human impact on global climate. Although some 80 states, plus the European Union signed the Kyoto Protocol, it remains unclear when it will come into force because the majority of states have failed to ratify it, pending the resolution of a variety of technical and operational details. Canada is the second highest emitter of greenhouse gases (16 tonnes per capita, compared to world average of 3.6 tonnes per capita). This, combined with Canada's foreign policy goals of playing a leading role in taking action and preserving its reputation as an honest broker, makes the challenge of meeting Canada's Kyoto commitments especially pressing. The purpose of this paper is to explain Canada's climate change policy in the context of these international and domestic pressures. The paper identifies the main climate change-related policy challenges, international responses to date and the constraints and opportunities open to Canada in the light of its economy, its federalist political structure, and place in the world as a middle power, as well as its geographic situation, natural resources and environmental endowment. There is a detailed discussion of the Kyoto

  16. Gender context of personalism in bioethics.

    Amzat, Jimoh; Grandi, Giovanni

    2011-12-01

    Personalism is one of the philosophical perspectives which hold that the reality in person and the human person has the highest intrinsic value. This paper makes reference to Louis Janssens' eight criteria in adequate consideration of the human person but further argues that there is need to consider people as situated agents especially within gender relational perspectives. The paper identifies gender as an important social construction that shapes the consideration of the human persons within socio-spatial spheres. The main crux of the paper is that there is a gender context of personalism and this has profound implications for bioethical agendas. Gender is part of the human condition, especially when we philosophically or sociologically engage the notion of equity and equality within the social system, because social realities in the relational perspective are not impartial, impersonal and equal. Gender does not determine morality but it plays a role in morality and expectations from moral agents. Women have been categorised as a sociological group because their integrity, freedom/autonomy and dignity (which are basic concerns of bioethics) are capable of being threatened. A gender perspective provides important incentives for moral theory which searches for possible conceptual imbalances or blind spots in ethical reflections. The paper refers to Sen's faces of gender inequality and expands on the notion that natality inequality is one of the fundamental levels of gender inequality, which in turn is the primary starting agenda in bioethics. The paper avers that the recognition of the fundamental importance of gender to the organization of social reality and the development of personal identities have important practical implications for bioethics. © 2011 Blackwell Publishing Ltd.

  17. Statistics of high-level scene context.

    Greene, Michelle R

    2013-01-01

    CONTEXT IS CRITICAL FOR RECOGNIZING ENVIRONMENTS AND FOR SEARCHING FOR OBJECTS WITHIN THEM: contextual associations have been shown to modulate reaction time and object recognition accuracy, as well as influence the distribution of eye movements and patterns of brain activations. However, we have not yet systematically quantified the relationships between objects and their scene environments. Here I seek to fill this gap by providing descriptive statistics of object-scene relationships. A total of 48, 167 objects were hand-labeled in 3499 scenes using the LabelMe tool (Russell et al., 2008). From these data, I computed a variety of descriptive statistics at three different levels of analysis: the ensemble statistics that describe the density and spatial distribution of unnamed "things" in the scene; the bag of words level where scenes are described by the list of objects contained within them; and the structural level where the spatial distribution and relationships between the objects are measured. The utility of each level of description for scene categorization was assessed through the use of linear classifiers, and the plausibility of each level for modeling human scene categorization is discussed. Of the three levels, ensemble statistics were found to be the most informative (per feature), and also best explained human patterns of categorization errors. Although a bag of words classifier had similar performance to human observers, it had a markedly different pattern of errors. However, certain objects are more useful than others, and ceiling classification performance could be achieved using only the 64 most informative objects. As object location tends not to vary as a function of category, structural information provided little additional information. Additionally, these data provide valuable information on natural scene redundancy that can be exploited for machine vision, and can help the visual cognition community to design experiments guided by statistics

    2013-12-01

    Full Text Available Holistic approach in many disciplines assumes that each component actually contains information about the whole as a unit. A holistic view of an interorganizational collaboration structure should provide a description based on simple laws of all connections between entities (nodes and network external universe. This approach is claimed on the basis that each entity reflects and contains the network and this, in turn, contains the entire footprint. Biology, chemistry and physics base their theories on a specific law of evolution of man, human group or physic-chemical structure. These sciences state that everything is evolving and suffers constant changes, the human evolution, the evolution of society - and social groups in particular - going through a succession of continue or choppy innovations. Sometimes, a phase or a situation seems new just because the context is changed. Innovation is viewed in a holistic way, so just as a new perception of those involved in the innovative process, just a different aspect of how to see and feel the world. The rules and regularities of the whole are constant presences. Life, social and economic systems, in all their complexity, are subjected to the same laws of evolution being processes of continuous innovation. In terms of innovative process, decisions are not taken between good and evil, or between right and wrong, but between good and better. Although it is applied correctly, an effective process of selecting ideas that will be transformed into innovations is not a prerequisite for choosing the best variant. Once introduced into the process of launching and exploitation in the market, an innovation that can bring profit to companies may actually be an incremental innovation that eliminated the possibility of being selected a better innovation, a radical innovation.

  19. Energy in Ireland: context, strategy and research

    Saintherant, N.; Lerouge, Ch.; Welcker, A.

    2008-01-01

    In the present day situation of sudden awareness about climatic change and announced fossil fuels shortage, Ireland has defined a new strategy for its energy future. Context: Ireland is strongly dependent of oil and gas imports which increase regularly to meet the demand. A small part of the electricity consumed is imported from Ulster. The share of renewable energies remains weak but is increasing significantly. Therefore, from 1990 to 2006, the proportion of renewable energies increased from 1.9% (mainly of hydroelectric origin) to 4.5%. Wind power represents now the main renewable energy source. The transportation sector is the most energy consuming and the biggest source of greenhouse gases. Strategy: the Irish policy is driven by pluri-annual strategic plans which define the objectives and means. Priority is given to the security of supplies at affordable prices: 8.5 billion euros will be invested during the 2007-2013 era for the modernization of existing energy infrastructures and companies, and in a lesser extent for the development of renewable energy sources. During this period, 415 million euros more will be devoted to the research, development and demonstration (RD and D) of new energy solutions. Research: in 2005 the energy RD and D expenses reached 12.8 million euros shared between 54% for R and D and 46% for demonstration projects. Half of the financing is given to higher education schools and is devoted to energy saving purposes (33%) and to renewable energies (29%, mainly wind power and biomass). Academic research gives a particular attention to ocean energy which represents an important potential resource in Ireland and which has already led to the creation of innovative companies. The integration of renewable energy sources to the power grid and the stability of supplies are also the object of active researches. (J.S.)

    The article argues for the importance of an open, reflexive-methodological approach when switching between studying text, context and researcher activity. Close linguistic analysis can benefit from being linked with the researcher’s contextualisation of his empirical material as well as with more distanced readings. The more specific starting point for this article is that school development, like other similar terms such as school improvement and the like, makes use of linguistic building blocks with which whole narratives about today’s and tomorrow’s schools can be constructed. The subject of the study is a short text issued by the Swedish Schools Inspectorate (Skolinspektionen. Government language changes according to the authorities’ role in society and their own definitions of their functions, and an important aspect here is the legitimacy of the authorities’ texts. By means of various kinds of close linguistic analysis, the above-mentioned text is studied with regard to choice of categories, hierarchies of modalisation and the rhetorical effects of different types of formulations in a broader political-social landscape. The article concludes with a reflective discussion on the relationship between government language and irony as a stylistic device – a device that is based on the results of the close empirical analysis.[i]

    Full Text Available Porquier (1984 defines the exolingual communication as the communication between individuals who do not share a common language, in opposition to endolingual communication, which is the communication between individuals sharing the same native language. Calling in this opposition, our paper brings forward the problem of intercomprehension and incomprehension in the endolingual space. Intercomprehension is nowadays almost exclusively associated to plurilinguism and a series of curricula of foreign language simultaneous learning. It is considered that the exolingual situation is by excellence a state of communicational risk and its management is more difficult, for it does not guarantee the success in communication. Polarizing the research in this direction unfortunately casts a shadow on the opportunity of debates on intercomprehension in one’s native tongue. And this is due, as Tyvaert (2008 showed, to the fact that “we should avoid pretending from linguistic intercomprehension what cannot be accomplished by intralinguistic intercomprehension”. It is naturally acceptable that the lack of intercomprehension leads to incomprehension, therefore to the misinterpretation or annulment of communication between people speaking the same language. In the context of linguistic training of future economists, we consider that the lack of intercomprehension in one’s native tongue often originates in the deficiencies of speciality knowledge. Therefore, we can state that an economist who does not understand an economic message in his native tongue cannot generate “endolingual intercomprehension”. According to a recent study on a representative sample of students from the Faculty of Economic Sciences of Oradea, we have tried to prove the above hypothesis and to render the students sensitive regarding the study of foreign languages. The results entitle us to consider that the lack of intralingustic intercomprehension (due to deficiencies in the

  2. Narratives of neoliberalism: 'clinical labour' in context.

    Science.gov (United States)

    Parry, Bronwyn

    2015-06-01

    Cross-border reproductive care has been thrust under the international spotlight by a series of recent scandals. These have prompted calls to develop more robust means of assessing the exploitative potential of such practices and the need for overarching and normative forms of national and international regulation. Allied theorisations of the emergence of forms of clinical labour have cast the outsourcing of reproductive services such as gamete donation and gestational surrogacy as artefacts of a wider neoliberalisation of service provision. These accounts share with many other narratives of neoliberalism a number of key assertions that relate to the presumed organisation of labour relations within this paradigm. This article critically engages with four assumptions implicit in these accounts: that clinical labourers constitute a largely homogeneous underclass of workers; that reproductive labour has been contractualised in ways that disembed it from wider social and communal relations; that contractualisation can provide protection for clinical labour lessening the need for formal regulatory oversight; and that the transnationalisation of reproductive service labour is largely unidirectional and characterised by a dynamic of provision in which 'the rest' services 'the West'. Drawing on the first findings of a large-scale ethnographic research project into assisted reproduction in India I provide evidence to refute these assertions. In so doing the article demonstrates that while the outsourcing and contractualisation of reproductive labour may be embedded in a wider neoliberal paradigm these practices cannot be understood nor their impacts be fully assessed in isolation from their social and cultural contexts.

    2015-01-01

    Design and implementation of a WSN (Wireless Sensor Network) that can efficiently work for a longer time period must include identification of the deployment environment context and to conform to the behavior of the sensor nodes. The context information when treated with evaluation factor becomes a process of context awareness and the evaluation factor is called the context attribute. In this paper, we consider the context factor of energy. The paper identifies analyses and evaluates efficiency of two when used in a context aware environment. Furthermore, the study also highlights the strengths and weaknesses of sensor SPIN (Sensor Protocol for Information via Negotiation) and LEACH (Low Energy Adaptive Clustering Hierarchy) protocols with respect to the support for WSN with heavy network traffic conditions. The performance has been evaluated in terms of energy efficiency, data packet transmission, network status, data management, reliability, etc. (author)

  4. Testing Automation of Context-Oriented Programs Using Separation Logic

    Directory of Open Access Journals (Sweden)

    Mohamed A. El-Zawawy

    2014-01-01

    Full Text Available A new approach for programming that enables switching among contexts of commands during program execution is context-oriented programming (COP. This technique is more structured and modular than object-oriented and aspect-oriented programming and hence more flexible. For context-oriented programming, as implemented in COP languages such as ContextJ* and ContextL, this paper introduces accurate operational semantics. The language model of this paper uses Java concepts and is equipped with layer techniques for activation/deactivation of layer contexts. This paper also presents a logical system for COP programs. This logic is necessary for the automation of testing, developing, and validating of partial correctness specifications for COP programs and is an extension of separation logic. A mathematical soundness proof for the logical system against the proposed operational semantics is presented in the paper.

    One experiment in human predictive learning explored the impact of a context change on attention to contexts and predictive ratings controlled by the cue. In Context A: cue X was paired with an outcome four times, while cue Y was presented without an outcome four times in Context B:. In both contexts filler cues were presented without the outcome. During the test, target cues X and Y were presented either in the context where they were trained, or in the alternative context. With the context change expectation of the outcome X, expressed as predictive ratings, decreased in the presence of X and increased in the presence of Y. Looking at the contexts, expressed as a percentage of the overall gaze dwell time on a trial, was high across the four training trials, and increased with the context change. Results suggest that the presentation of unexpected information leads to increases in attention to contextual cues. Implications for contextual control of behavior are discussed.

    A basic premise of the recently proffered color-in-context model is that the influence of color on psychological functioning varies as a function of the psychological context in which color is perceived. Some research has examined the appetitive and aversive implications of viewing the color red in romance- and achievement-relevant contexts, respectively, but in all existing empirical work approach and avoidance behavior has been studied in separate tasks and separate experiments. Research is needed to directly test whether red influences the same behavior differently depending entirely on psychological context. The present experiment was designed to put this premise to direct test in romance- and achievement-relevant contexts within the same experimental paradigm involving walking behavior. Our results revealed that exposure to red (but not blue) indeed has differential implications for walking behavior as a function of the context in which the color is perceived. Red increased the speed with which participants walked to an ostensible interview about dating (a romance-relevant context), but decreased the speed with which they walked to an ostensible interview about intelligence (an achievement-relevant context). These results are the first direct evidence that the influence of red on psychological functioning in humans varies by psychological context. Our findings contribute to both the literature on color psychology and the broader, emerging literature on the influence of context on basic psychological processes.

  10. Uninformative contexts support word learning for high-skill spellers.

    The current study investigated how high-skill spellers and low-skill spellers incidentally learn words during reading. The purpose of the study was to determine whether readers can use uninformative contexts to support word learning after forming a lexical representation for a novel word, consistent with instance-based resonance processes. Previous research has found that uninformative contexts damage word learning; however, there may have been insufficient exposure to informative contexts (only one) prior to exposure to uninformative contexts (Webb, 2007; Webb, 2008). In Experiment 1, participants read sentences with one novel word (i.e., blaph, clurge) embedded in them in three different conditions: Informative (six informative contexts to support word learning), Mixed (three informative contexts followed by three uninformative contexts), and Uninformative (six uninformative contexts). Experiment 2 added a new condition with only three informative contexts to further clarify the conclusions of Experiment 1. Results indicated that uninformative contexts can support word learning, but only for high-skill spellers. Further, when participants learned the spelling of the novel word, they were more likely to learn the meaning of that word. This effect was much larger for high-skill spellers than for low-skill spellers. Results are consistent with the Lexical Quality Hypothesis (LQH) in that high-skill spellers form stronger orthographic representations which support word learning (Perfetti, 2007). Results also support an instance-based resonance process of word learning in that prior informative contexts can be reactivated to support word learning in future contexts (Bolger, Balass, Landen, & Perfetti, 2008; Balass, Nelson, & Perfetti, 2010; Reichle & Perfetti, 2003).

    Literature assumes that negation is more difficult to understand than affirmation, but this might depend on the pragmatic context. The goal of this paper is to show that pragmatic knowledge modulates the unfolding processing of negation due to the previous activation of the negated situation. To test this, we used the visual world paradigm. In this task, we presented affirmative (e.g., her dad was rich) and negative sentences (e.g., her dad was not poor) while viewing two images of the affirmed and denied entities. The critical sentence in each item was preceded by one of three types of contexts: an inconsistent context (e.g., She supposed that her dad had little savings) that activates the negated situation (a poor man), a consistent context (e.g., She supposed that her dad had enough savings) that activates the actual situation (a rich man), or a neutral context (e.g., her dad lived on the other side of town) that activates neither of the two models previously suggested. The results corroborated our hypothesis. Pragmatics is implicated in the unfolding processing of negation. We found an increase in fixations on the target compared to the baseline for negative sentences at 800 ms in the neutral context, 600 ms in the inconsistent context, and 1450 ms in the consistent context. Thus, when the negated situation has been previously introduced via an inconsistent context, negation is facilitated.

    Context aware applications respond and adapt to changes in the computing environment. It is the concept of leveraging information about the end user to improve the quality of the interaction. New technologies in context-enriched services will use location, presence, social attributes, and other environmental information to anticipate an end user's immediate needs, offering more-sophisticated, situation-aware and usable functions. Smart homes connect all the devices and appliances in your home so they can communicate with each other and with you. Context-awareness can be applied to Smart Home technology. In this paper, we discuss the context-aware tools for development of Smart Home Systems.

    2013-06-01

    Nuclear Power forms an essential part of the strategies deployed to provide the future global energy demands whilst meeting the obligations on CO 2 emission reduction targets. In the UK, plans across the political spectrum call for a substantial nuclear new-build (NNB) programme. This necessitates application of best practice design, fabrication and welding technology in the UK context as well as a consideration of current and future skill requirements. Existing nuclear technology covers a range of different designs, and many reactors have reached the end of their design life. The decommissioning of old plants and management of nuclear waste, especially high-level, long-life and spent fuel waste, therefore also requires ongoing attention. Welding is defined by ISO as a 'special process', as imperfections in welded/fabricated products, even after inspection, may become apparent only after the product is put in use or service. Thus, welding has a major influence on the quality and cost of the final product, as well as the operational and maintenance costs. Most current trends in welding process innovations focus on improving weld quality and productivity, or reducing the dependency on welder/operator skills. Materials research concentrates on improving the understanding of influence of the environment (irradiation, temperature, corrosion, fatigue) on long-term performance and on repair of existing plants or future designs that will require higher temperature materials. The ITER nuclear fusion and the Jules-Horowitz Research reactors also have unique demands on materials and welding processes. Through the Engineering the Future alliance, the UK has organised a review of the international lessons learnt during recent nuclear new-build projects, and welding has been identified as a critical area requiring particular attention for any future new-build activities. TWI chaired the group advising on welding issues resulting in recommendations for the UK NNB programme. Key

  16. False memory for context and true memory for context similarly activate the parahippocampal cortex.

    2017-06-01

    The role of the parahippocampal cortex is currently a topic of debate. One view posits that the parahippocampal cortex specifically processes spatial layouts and sensory details (i.e., the visual-spatial processing view). In contrast, the other view posits that the parahippocampal cortex more generally processes spatial and non-spatial contexts (i.e., the general contextual processing view). A large number of studies have found that true memories activate the parahippocampal cortex to a greater degree than false memories, which would appear to support the visual-spatial processing view as true memories are typically associated with greater visual-spatial detail than false memories. However, in previous studies, contextual details were also greater for true memories than false memories. Thus, such differential activity in the parahippocampal cortex may have reflected differences in contextual processing, which would challenge the visual-spatial processing view. In the present functional magnetic resonance imaging (fMRI) study, we employed a source memory paradigm to investigate the functional role of the parahippocampal cortex during true memory and false memory for contextual information to distinguish between the visual-spatial processing view and the general contextual processing view. During encoding, abstract shapes were presented to the left or right of fixation. During retrieval, old shapes were presented at fixation and participants indicated whether each shape was previously on the "left" or "right" followed by an "unsure", "sure", or "very sure" confidence rating. The conjunction of confident true memories for context and confident false memories for context produced activity in the parahippocampal cortex, which indicates that this region is associated with contextual processing. Furthermore, the direct contrast of true memory and false memory produced activity in the visual cortex but did not produce activity in the parahippocampal cortex. The present

    This report addresses the recent Department of Homeland Security (DHS) call for a Phase I study to (1) assess gaps in the forensically relevant knowledge about the population genetics of eight bacterial agents of concern, (2) formulate a technical roadmap to address those gaps, and (3) identify new bioinformatics tools that would be necessary to analyze and interpret population genetic data in a forensic context. The eight organisms that were studied are B. anthracis, Y. pestis, F. tularensis, Brucella spp., E. coli O157/H7, Burkholderia mallei, Burkholderia pseudomallei, and C. botulinum. Our study focused on the use of bacterial population genetics by forensic investigators to test hypotheses about the possible provenance of an agent that was used in a crime or act of terrorism. Just as human population genetics underpins the calculations of match probabilities for human DNA evidence, bacterial population genetics determines the level of support that microbial DNA evidence provides for or against certain well-defined hypotheses about the origins of an infecting strain. Our key findings are: (1) Bacterial population genetics is critical for answering certain types of questions in a probabilistic manner, akin (but not identical) to 'match probabilities' in DNA forensics. (2) A basic theoretical framework for calculating likelihood ratios or posterior probabilities for forensic hypotheses based on microbial genetic comparisons has been formulated. This 'inference-on-networks' framework has deep but simple connections to the population genetics of mtDNA and Y-STRs in human DNA forensics. (3) The 'phylogeographic' approach to identifying microbial sources is not an adequate basis for understanding bacterial population genetics in a forensic context, and has limited utility, even for generating 'leads' with respect to strain origin. (4) A collection of genotyped isolates obtained opportunistically from international locations

    Vivid episodic memories in people have been characterized as the replay of unique events in sequential order [1-3]. Animal models of episodic memory have successfully documented episodic memory of a single event (e.g., [4-8]). However, a fundamental feature of episodic memory in people is that it involves multiple events, and notably, episodic memory impairments in human diseases are not limited to a single event. Critically, it is not known whether animals remember many unique events using episodic memory. Here, we show that rats remember many unique events and the contexts in which the events occurred using episodic memory. We used an olfactory memory assessment in which new (but not old) odors were rewarded using 32 items. Rats were presented with 16 odors in one context and the same odors in a second context. To attain high accuracy, the rats needed to remember item in context because each odor was rewarded as a new item in each context. The demands on item-in-context memory were varied by assessing memory with 2, 3, 5, or 15 unpredictable transitions between contexts, and item-in-context memory survived a 45 min retention interval challenge. When the memory of item in context was put in conflict with non-episodic familiarity cues, rats relied on item in context using episodic memory. Our findings suggest that rats remember multiple unique events and the contexts in which these events occurred using episodic memory and support the view that rats may be used to model fundamental aspects of human cognition.

  20. Context cue focality influences strategic prospective memory monitoring.

    Monitoring the environment for the occurrence of prospective memory (PM) targets is a resource-demanding process that produces cost (e.g., slower responding) to ongoing activities. However, research suggests that individuals are able to monitor strategically by using contextual cues to reduce monitoring in contexts in which PM targets are not expected to occur. In the current study, we investigated the processes supporting context identification (i.e., determining whether or not the context is appropriate for monitoring) by testing the context cue focality hypothesis. This hypothesis predicts that the ability to monitor strategically depends on whether the ongoing task orients attention to the contextual cues that are available to guide monitoring. In Experiment 1, participants performed an ongoing lexical decision task and were told that PM targets (TOR syllable) would only occur in word trials (focal context cue condition) or in items starting with consonants (nonfocal context cue condition). In Experiment 2, participants performed an ongoing first letter judgment (consonant/vowel) task and were told that PM targets would only occur in items starting with consonants (focal context cue condition) or in word trials (nonfocal context cue condition). Consistent with the context cue focality hypothesis, strategic monitoring was only observed during focal context cue conditions in which the type of ongoing task processing automatically oriented attention to the relevant features of the contextual cue. These findings suggest that strategic monitoring is dependent on limited-capacity processing resources and may be relatively limited when the attentional demands of context identification are sufficiently high.

    The aim of the present study was to explore sex differences in the effects that emotional contexts exert on the temporal course of response inhibition using event-related potentials (ERP). Participants performed a Go-NoGo response inhibition task under 3 context conditions: with 1) neutral background stimuli, and 2) pleasant, and 3) unpleasant emotional contexts. No sex differences were found in relation to accuracy. Women showed higher N2NoGo amplitudes than men in both emotional contexts; whereas during inhibition men tended to show higher P3NoGo amplitudes than women in the unpleasant context. Both groups experienced a relevant effect of the presence of the unpleasant context during inhibition processing, as shown by the enhancement of the N2NoGo amplitudes in frontal regions compared to results from the neutral and pleasant conditions. In addition, women showed differences between the pleasant and unpleasant contexts, with the latter inducing higher amplitude values. Only in men did inhibition accuracy correlate with higher N2NoGo and lower P3NoGo amplitudes in the emotional context conditions. These findings suggest that when an inhibition task is performed in an emotionally-neutral background context no sex differences are observed in either accuracy or ERP components. However, when the emotional context was introduced -especially the unpleasant one- some gender differences did become evident. The higher N2NoGo amplitude at the presence of the unpleasant context may reflect an effect on attention and conflict monitoring. In addition, results suggest that during earlier processing stages, women invested more resources to process inhibition than men. Furthermore, men who invested more neural resources during earlier stages showed better response inhibition than those who did it during later processing stages, more closely-related to cognitive and motor inhibition processes.

    Currently there are few published, multilevel studies of physical assault victimization of prisoners. This study builds on the extant research by utilizing a nationally representative sample of correctional facilities (n = 326) and inmates (n = 17,640) to examine the impacts of a large set of theoretically and empirically derived individual- and contextual-level variables on prison victimization, including how the gendered context of prison impacts victimization. Results support the lifestyles/routine activities approach. Inmates who were charged with a violent offense, were previously victimized, were smaller in size, were not married, were without a work assignment, misbehaved, did not participate in programs, used alcohol or drugs, and those who had a depression or personality disorder were more likely to be victimized. In addition, the data suggest that 8% of the variance in victimization is due to the prison context. Prisons with high proportions of violent offenders, males, inmates from multiracial backgrounds, and inmates with major infractions had increased odds of victimization. Moreover, the sex-composition of the prison has significant main and interactive effects predicting victimization. Specifically, we find that the effects of being convicted of a drug crime, drug use, military service, major infractions, and diagnosed personality disorders are all gendered in their impacts on victimization. © The Author(s) 2015.

  3. Others in post-conflict contexts

    Full Text Available Researches conducted so far within the project Spinning out of control: rhetoric and violent conflict. Representations of 'self' - 'other' in the Yugoslav successor states focused on exploring the relations towards the Other in a state of conflict. Moreover: most of the author's and coauthors' contributions were oriented towards discourse analysis in the context of violence. Except for the peaceful dismemberment of Montenegro and Serbia, proclamation of independence of other Yugoslav states did not go without violence, to a greater or lesser extent. The Other in these situations was predominantly the ethnic Other, and usually treated as enemy. For that reason, the greater part of our past work was oriented towards analysing media reports of the most stiking war events. Also, some of the contributions intentionally targeted media reportings of tense situations and those bearing the unpredictable outcomes, such as referenda or meetings discussing war and peace matters; or, we focused our inquiries on radical standpoints expressed by certain media or political parties - all that in order to explore the essencial forms of constructing and manifesting the Otherness on a rhetoric level. From a broader perspective, the analysed period, marked by the wars of ex - Yugoslavia in the last decade of 20th century, could be comprehended as the preiod of a state of emergency, where the old order had been brutally and radically destroyed and the new one was installed. In such a process, as it was shown, the relation towards the Other was also usually extreme and ethnically motivated. Now, after the constitution of seven new states where once former Yugoslavia was, new questions emerge. We are interested, as we were before, in the identity constructions, especially in the relations toward the Other, and Otherness in general, now in the period of transition and normalization of mutual relationships that these societies are undergoing.

    The law provides that long-term management of long-lived, high-level waste comprises two aspects, which are not mutually exclusive: the partitioning and transmutation of the actinides present in spent fuel from nuclear reactors, and the geological disposal of long-lived high- and intermediate-level waste. This report is organised to reflect the two complementary aspects of R and D on the management of radioactive waste and materials: partitioning and transmutation (chapter 1), and the storage and disposal of LLHL and LLIL waste (chapter 2). In 2011 the Board decided to go into detail on the subject of the potential impact of transmutation of actinides on the disposal of the waste produced in the future, in a set of reactors suitable for multi-recycling. This question is dealt with in two chapters of the report. The Board continues to observe the overall international situation (chapter 3), and this year devoted an entire hearing to the different visions of the nuclear cycle held throughout the world. This hearing took place a few weeks before the accident in Fukushima. Contents: Chapter 1 - Partitioning and transmutation: scientific and technical context; transmutation and multi-recycling (Three important actinides potentially concerned by transmutation: Plutonium, Americium, Curium; Transmutation rate); demonstration tools; scenarios; ASTRID prototype (Core, Cooling and conversion, Designs and materials for Astrid); Reprocessing and fabrication of fuel (Experience and lessons learned; Pilot reprocessing facility for Astrid); transmutation in ADS; transmutation and disposal (Radiotoxicity of the inventory; Residual thermal power in LLHL waste); other scenarios; conclusion; Chapter 2 - disposal and storage: introduction; inventory; ZIRA (Contributions of the new 3D geophysics campaign; Knowledge of lithostratigraphic variations in the Callovo-Oxfordian layer; Knowledge of regional and local hydrogeology; Hydrogeological modelling situation); ZIIS - Integration of

    Fear acquisition and extinction have been demonstrated as core mechanisms for the development and maintenance of mental disorders, with different contributions of processing cues vs contexts. The hypothalamic peptide oxytocin (OXT) may have a prominent role in this context, as it has been shown to affect fear learning. However, investigations have focused on cue conditioning, and fear extinction. Its differential role for cue and context fear acquisition is still not known. In a randomized, double-blind, placebo (PLC)-controlled design, we administered an intranasal dose of OXT or PLC before the acquisition of cue and context fear conditioning in healthy individuals (n = 52), and assessed brain responses, skin conductance responses and self-reports (valence/arousal/contingency). OXT compared with PLC significantly induced decreased responses in the nucleus accumbens during early cue and context acquisition, and decreased responses of the anterior cingulate cortex and insula during early as well as increased hippocampal response during late context, but not cue acquisition. The OXT group additionally showed significantly higher arousal in late cue and context acquisition. OXT modulates various aspects of cue and context conditioning, which is relevant from a mechanism-based perspective and might have implications for the treatment of fear and anxiety. © The Author (2017).

    Extinction of conditioned fear represents an important mechanism in the treatment of anxiety disorders. Return of fear after successful extinction or exposure therapy in patients with anxiety disorders might be linked to poor temporal or contextual generalization of extinction due to individual differences in brain structural connectivity. The goal of this magnetic resonance imaging study was therefore to investigate the association of context-dependent extinction recall with brain structural connectivity. Diffusion-tensor imaging was used to determine the fractional anisotropy as a measure of white matter structural integrity of fiber tracts connecting central brain regions of the fear and extinction circuit (uncinate fasciculus, cingulum). Forty-five healthy men participated in a two-day fear conditioning experiment with fear acquisition in context A and extinction learning in context B on the first day. Extinction recall in the extinction context as well as renewal in the acquisition context and a novel context C took place one day later. Renewal of conditioned fear (skin conductance responses) in the acquisition context was associated with higher structural integrity of the hippocampal part of the cingulum. Enhanced structural integrity of the cingulum might be related to stronger hippocampal modulation of the dorsal anterior cingulate cortex, a region important for modulating conditioned fear output by excitatory projections to the amygdala. This finding underpins the crucial role of individual differences in the structural integrity of relevant fiber tracts for context-dependent extinction recall and return of fear after exposure therapy in anxiety disorders. © 2017 Wiley Periodicals, Inc.
