Social NUI: Social perspectives in natural user interfaces

Natural User Interfaces (NUI) offer rich ways for interacting with the digital world that make innovative use of existing human capabilities. They include and often combine different input modalities such as voice, gesture, eye gaze, body interactions, touch and touchless interactions. However much of the focus of NUI research and development has been on enhancing the experience of individuals interacting with technology. Effective NUIs must also acknowledge our innately social characteristics, and support how we communicate with each other, play together, learn together and collaboratively work together. This workshop concerns the social aspects of NUI. The workshop seeks to better understand the social uses and applications of these new NUI technologies -- how we design these technologies for new social practices and how we understand the use of these technologies in key social contexts.

A comparative phase 1 clinical trial to identify anti-infective mechanisms of vitamin D in people with HIV infection

Objectives:To determine if there is a biological mechanism that explains the association between HIV disease progression and increased mortality with low circulating vitamin D levels; specifically, to determine if restoring vitamin D levels induced T-cell functional changes important for antiviral immunity.Design:This was a pilot, open-label, three-arm prospective phase 1 study.Methods:We recruited 28 patients with low plasma vitamin D (<50nmol/l 25-hydroxyvitamin D3), comprising 17 HIV+ patients (11 on HAART, six treatment-naive) and 11 healthy controls, who received a single dose of 200000IU oral cholecalciferol. Advanced T-cell flow cytometry methods measured CD4(+) T-cell function associated with viral control in blood samples at baseline and 1-month after vitamin D supplementation.Results:One month of vitamin D supplementation restored plasma levels to sufficiency (>75nmol/l) in 27 of 28 patients, with no safety issues. The most striking change was in HIV+ HAART+ patients, where increased frequencies of antigen-specific T cells expressing macrophage inflammatory protein (MIP)-1 - an important anti-HIV blocking chemokine - were observed, with a concomitant increase in plasma MIP-1, both of which correlated significantly with vitamin D levels. In addition, plasma cathelicidin - a vitamin D response gene with broad antimicrobial activity - was enhanced.Conclusion:Vitamin D supplementation modulates disease-relevant T-cell functions in HIV-infected patients, and may represent a useful adjunct to HAART therapy.

Mapping social change in U.S. coastal counties: a social atlas of coastal North Carolina

This document represents a pilot effort to map social change in the coastal United States—a social atlas characterizing changing population, demographic, housing, and economic attributes. This pilot effort focuses on coastal North Carolina. The impetus for this project came from numerous discussions about the usefulness and need for a graphic representation of social change information for U.S. coastal regions. Although the information presented here will be of interest to a broad segment of the coastal community and general public, the intended target audience is coastal natural resource management professionals, Sea Grant Extension staff, urban and regional land-use planners, environmental educators, and other allied constituents interested in the social aspects of how the nation’s coasts are changing. This document has three sections. The first section provides background information about the project. The second section features descriptions of social indicators and depictions of social indicator data for 1970, 1980, 1990, and 2000, and changes from 1970 to 2000 for all North Carolina coastal counties. The third section contains three case studies describing changes in select social attributes for subsets of counties. (PDF contains 67 pages)

O passado no presente: estudo das memórias e representações sociais de profissionais de saúde no contexto da epidemia do HIV/Aids

O presente estudo tem como objetivo analisar os conteúdos das memórias sociais, construídas por profissionais de saúde, acerca da epidemia do HIV/Aids no Brasil, desde o seu surgimento até os dias atuais. Trata-se de um estudo exploratório-descritivo, pautado na abordagem qualitativa, orientado pela Teoria das Representações Sociais, em interseção com as Memórias Sociais. Os sujeitos do estudo foram 23 profissionais de saúde graduados de serviços ambulatoriais e/ou da atenção básica, atuantes em 18 instituições públicas de saúde da cidade do Rio de Janeiro que possuem o Programa Nacional de DST/Aids. A coleta de dados deu-se por meio de um roteiro de entrevista semiestruturada e um questionário de caracterização sócio profissional. Para a análise dos dados foi utilizada a técnica de análise lexical, realizada pelo software ALCESTE 4.10. Na análise do grupo total de sujeitos foram definidas três categorias denominadas: As primeiras décadas da epidemia: a formação da representação social do HIV/Aids e das memórias, abordando a formação das representações e os elementos de memória nas décadas de 80 e 90; As práticas multiprofissionais e o atendimento à pessoa com HIV/Aids nos dias atuais, abordando a cotidianidade e as representações acerca do HIV/Aids na atualidade e Formas de transmissão e precaução pessoal e profissional, abordando a precaução pessoal e profissional implicada na prevenção, enquanto conteúdo atemporal e transversal aos períodos analisados. A análise dos dados revelou que os profissionais de saúde delimitaram as memórias acerca da Aids no inicio da epidemia, associadas ao homossexualidade e à morte, tendo as mesmas se estruturado através da difusão dos conhecimentos estabelecidos na época pela mídia e pelo aparecimento dos primeiros casos assistidos pelos profissionais, que determinaram um cenário de estereótipos atrelados ao HIV e à Aids. A década de 90 foi relembrada como aquela de uma nova esperança com a inserção dos antirretrovirais e o estabelecimento de protocolos de acompanhamento determinando o início de uma mudança da representação. Na atualidade, as representações reconstroem a dinâmica estabelecida pelo Programa de Aids e Hepatites Virais enfatizando o papel das equipes multiprofissionais, a interdisciplinaridade, o tratamento e as práticas de cuidado. Observa-se a inserção de uma nova dinâmica relacionada à diminuição da importância da morte e da homossexualidade na centralidade da representação e a inserção de outros elementos relacionados ao Programa de Aids e Hepatites Virais estabelecido. Conclui-se que as memórias e representações sociais acerca do HIV/Aids e das pessoas acometidas foram construídas com base nas práticas de saúde estabelecidas pelos profissionais e, ainda, apoiadas nas características dos pacientes com Aids em cada período, conforme representadas.

Memórias da equipe de enfermagem na primeira década da epidemia da Aids

Na década de 80 dramáticas ocorrências atingiram o país e o mundo na área da saúde com a descoberta da Síndrome da Imunodeficiência Adquirida (Aids) síndrome, causada pelo Vírus da Imunodeficiência Humana (HIV). O objetivo deste estudo foi descrever as representações sociais do HIV/Aids e as memórias sociais do cuidado de enfermagem construídas na década de 80 pela equipe de enfermagem. Optou-se por uma abordagem qualitativa, embasada na teoria de representações sociais e nos conceitos do campo da memória social. Os sujeitos do estudo foram 20 profissionais de enfermagem de serviços ambulatoriais e/ou da atenção básica, atuantes em 11 instituições públicas de saúde da cidade do Rio de Janeiro que possuem o Programa Nacional de DST/Aids. A coleta de dados foi realizada através de entrevista semiestruturada e questionário de caracterização sócio profissional. A análise dos dados deu-se em duas etapas, a primeira atraves da técnica de análise de conteúdo temática destinada a identificar nos depoimentos dos entrevistados os conteúdos discursivos relativos a década de 80. Posteriormente os trechos selecionados foram submetidos à análise lexical pelo software Alceste 4.10. Obteve-se três classes temáticas que abordaram: As percepções e as ações do cuidado de enfermagem na década de 80; Os primeiros contatos profissionais e pessoais com HIV/Aids e A mídia e a construção das representações sociais do HIV/Aids. Na primeira classe os profissionais de enfermagem relatam as memórias referentes aos cuidados prestados na década de 80, descrevendo como esse cuidado era prestado, o medo da contaminação e os profissionais que atuavam na prestação de serviços. Na classe 2 os sujeitos resgatam as primeiras vivências com as pessoas com HIV/Aids e os sentimentos experimentados neste primeiro contato. As características físicas, os aspectos emocionais, a introdução do AZT e o abandono familiar são elementos destacados. Na classe 3 são relatas as memórias referentes ao início da epidemia de HIV/Aids, com destaque para as ancoragens representacionais do surgimento do vírus, tendo especialmente o macaco como hospedeiro. Os meios de comunicação surgiram como formadores das memórias do início da epidemia, veiculando imagens, como a do cantor Cazuza, fortemente citado pelos sujeitos. Conclui-se que este estudo permitiu compreender, através das memórias e das representações, como se constituiu a atuação dos profissionais no início da epidemia, assim como a permanência de elementos simbólicos até hoje nas representações sociais do HIV/Aids.

Cuidado em saúde à pessoa que vive com HIV/Aids: representações sociais de enfermeiros e médicos

O presente estudo tem como objetivos identificar as representações sociais do cuidado em saúde à pessoa que vive com HIV/aids para enfermeiros e médicos, descrevendo-as através das abordagens estrutural e processual; comparar as representações de enfermeiros e médicos; e analisar o cuidado em saúde à pessoa que vive com HIV/aids a partir das representações construídas por esses profissionais. Trata-se de um estudo descritivo com abordagem qualitativa, orientado pela Teoria das Representações Sociais. Os participantes do estudo foram, numa primeira etapa, 81 profissionais, sendo 54 médicos e 27 enfermeiros que trabalham em instituições públicas com atuação voltada à testagem e ao atendimento à pessoa que vive com HIV/aids, onde responderam ao questionário sócio-profissional e de evocações livres. Na segunda etapa, conforme conveniência, participaram da entrevista semi-estruturada, 20 enfermeiros e 18 médicos. Para a análise dos dados utilizamos a técnica do quadro de quatro casas com a utilização do software EVOC 2005 e a análise lexical pelo software Alceste 4.0. Quanto à estrutura representacional geral, destaca-se no Núcleo Central os termos acolhimento, adesão-tratamento, futuro e informação, que refletem a estruturação do processo assistencial da prática do cuidado no seio do programa. Na zona de contraste foram identificados atenção, cuidado e educação-saúde, que reforçam o Núcleo Central. Destaca-se, ainda, o léxico cuidado trazendo a dimensão imagética da representação. Na análise realizada pelo Alceste foram definidas cinco classes: estrutura e dinâmica de atendimento às pessoas que vivem com HIV/aids; o processo de transmissão e de prevenção do HIV/aids: entre vítimas, culpados e profissionais; memórias e história da epidemia de HIV/aids contada por profissionais; o cuidado no contexto da equipe multidisciplinar: composição, desafios e conceitos; o programa nacional DST/Aids e sua implementação nas unidades de saúde: avaliação, memória e capacitação. Realizamos ainda, a análise cruzada dos termos cuidado de enfermagem e cuidado médico. Ao final do estudo, consideramos que a representação do cuidado em saúde para este grupo de profissionais mostrou-se positiva apesar das dificuldades encontradas em seu cotidiano laboral. A representação do cuidado em saúde à pessoa vivendo com HIV/aids para médicos e enfermeiros apoia-se no programa DST/Aids e no conhecimento científico que embasa cada profissão. Os profissionais valorizam o trabalho multidisciplinar e procuram tratar o cliente de forma respeitosa, incentivando a adesão ao tratamento através de informação e do apoio psicológico.

Distribution of CCR2-64I and SDF1-3 ' A alleles and HIV status in 7 ethnic populations of Cameroon

Limited information is available on the prevalence among rural Africans of host genetic polymorphisms conferring resistance to HIV-1 infection or slowing HIV disease progression.We report the allelic frequencies of the AIDS-related polymorphisms CCR2-64I, SDF1-3#A, and CCR5-D32 in 321 volunteers from 7 ethnic groups in Cameroon. Allelic frequencies differed among the 7 ethnic groups, ranging from 10.8% to 31.3% for CCR2-64I and 0.0% to 7.1% for SDF1-3#A. No CCR5-D32 alleles were found. HIV seroprevalence was 6.9% in the total population and peaked at younger ages in girls and women than in boys and men. Among 15- to 54-year-olds, HIV seroprevalence varied from 2.0% to 11.1% among the village populations. Conditional logistic regression analysis using data from boys and men aged 15 to 54 years showed the number of CCR2-64I alleles to be a significant risk factor for HIV seropositivity (odds ratio per allele adjusted for age and matched on ethnic group = 6.3, 95% confidence interval: 1.3–30.3); this association was not found in women. The findings are consistent with the hypothesis that CCR2-64I alleles may delay HIV disease progression without affecting susceptibility to infection among men. We did not observe this relation among women, and other factors, such as multiple pregnancies or maternal stressors (eg, breastfeeding), may have masked any protective effect of CCR2-64I alleles. Further study of this issue among women is warranted. SDF1-3#A did not differ between HIV-seropositive and HIV-seronegative individuals but wasassociated with increasing age among HIV-seronegative women, suggesting a protective effect against HIV-1 infection.

Comparative immunogenicity of HIV-1 clade C envelope proteins for prime/boost studies.

BACKGROUND: Previous clinical efficacy trials failed to support the continued development of recombinant gp120 (rgp120) as a candidate HIV vaccine. However, the recent RV144 HIV vaccine trial in Thailand showed that a prime/boost immunization strategy involving priming with canarypox vCP1521 followed by boosting with rgp120 could provide significant, although modest, protection from HIV infection. Based on these results, there is renewed interest in the development of rgp120 based antigens for follow up vaccine trials, where this immunization approach can be applied to other cohorts at high risk for HIV infection. Of particular interest are cohorts in Africa, India, and China that are infected with clade C viruses. METHODOLOGY/PRINCIPAL FINDINGS: A panel of 10 clade C rgp120 envelope proteins was expressed in 293 cells, purified by immunoaffinity chromatography, and used to immunize guinea pigs. The resulting sera were collected and analyzed in checkerboard experiments for rgp120 binding, V3 peptide binding, and CD4 blocking activity. Virus neutralization studies were carried out with two different assays and two different panels of clade C viruses. A high degree of cross reactivity against clade C and clade B viruses and viral proteins was observed. Most, but not all of the immunogens tested elicited antibodies that neutralized tier 1 clade B viruses, and some sera neutralized multiple clade C viruses. Immunization with rgp120 from the CN97001 strain of HIV appeared to elicit higher cross neutralizing antibody titers than the other antigens tested. CONCLUSIONS/SIGNIFICANCE: While all of the clade C antigens tested were immunogenic, some were more effective than others in eliciting virus neutralizing antibodies. Neutralization titers did not correlate with rgp120 binding, V3 peptide binding, or CD4 blocking activity. CN97001 rgp120 elicited the highest level of neutralizing antibodies, and should be considered for further HIV vaccine development studies.

Local perceptions of the QICS experimental offshore CO2 release: Results from social science research

This paper explores the social dimensions of an experimental release of carbon dioxide (CO2) carried out in Ardmucknish Bay, Argyll, United Kingdom. The experiment, which aimed to understand detectability and potential effects on the marine environment should there be any leakage from a CO2 storage site, provided a rare opportunity to study the social aspects of a carbon dioxide capture and storage-related event taking place in a lived-in environment. Qualitative research was carried out in the form of observation at public information events about the release, in-depth interviews with key project staff and local stakeholders/community members, and a review of online media coverage of the experiment. Focusing mainly on the observation and interview data, we discuss three key findings: the role of experience and analogues in learning about unfamiliar concepts like CO2 storage; the challenge of addressing questions of uncertainty in public engagement; and the issue of when to commence engagement and how to frame the discussion. We conclude that whilst there are clearly slippages between a small-scale experiment and full-scale CCS, the social research carried out for this project demonstrates that issues of public and stakeholder perception are as relevant for offshore CO2 storage as they are for onshore.

Shark personalities? Repeatability of social network traits in a widely distributed predatory fish. Behavioral Ecology and Sociobiology, 68, 1995-2003.

Interest in animal personalities has generated a burgeoning literature on repeatability in individual traits such as boldness or exploration through time or across different contexts. Yet, repeatability can be influenced by the interactive social strategies of individuals, for example, consistent inter-individual variation in aggression is well documented. Previous work has largely focused on the social aspects of repeatability in animal behaviour by testing individuals in dyadic pairings. Under natural conditions, individuals interact in a heterogeneous polyadic network. However, the extent to which there is repeatability of social traits at this higher order network level remains unknown. Here, we provide the first empirical evidence of consistent and repeatable animal social networks. Using a model species of shark, a taxonomic group in which repeatability in behaviour has yet to be described, we repeatedly quantified the social networks of ten independent shark groups across different habitats, testing repeatability in individual network position under changing environments. To understand better the mechanisms behind repeatable social behaviour, we also explored the coupling between individual preferences for specific group sizes and social network position. We quantify repeatability in sharks by demonstrating that despite changes in aggregation measured at the group level, the social network position of individuals is consistent across treatments. Group size preferences were found to influence the social network position of individuals in small groups but less so for larger groups suggesting network structure, and thus, repeatability was driven by social preference over aggregation tendency.

Interpersonal Aspects of Thinking Skills in an Intercultural Language Learning Context

Asking and answering certain types of questions are thought to develop thinking skills in all types of classrooms. Previous research has demonstrated that asking higher order questions and answering with elaborated responses are associated with high achievement in first, second, and foreign language contexts. Typically more attention is paid to question frequency or achievements inferred from individual performances than to the dialogues in which asking and answering occurs. This paper argues for a focus on the construction of responses in interaction as an alternative to the investigation of questions, effects of training or individual measurements of performance. Drawing on interactional data from an adult English as a Second Language classroom, it is argued that constructing an answer to a critical question appears to be a highly collaborative and evaluative affair. The thinking skills literature suggests that responding to higher order questions is an individual higher cognitive function, however it is argued in this paper that in attempting to construct evaluative answers language learners are involved not only in a cognitive task, which may or may not be helpful to language learning, but also in a complex social task in which perspectives need to be negotiated, stances taken and identities navigated. It is suggested that higher order thinking cannot be separated from the social and cultural knowledge through which it is brought into being. It is argued that any implementation of thinking skills in an English language teaching context ought to consider interpersonal and social aspects, particularly in intercultural settings.

Beyond Individualism: Social Work and Social Identity

Individualism continues to have a notable impact on social work. The personalisation of services and the individualisation of care are just two examples of this societal trend. While helping service users to articulate their aspirations for a better future, individualism, if taken too far, undermines the social aspects of life. In response to this concern, this paper argues that social work must appreciate the interplay between the individual and the collective spheres, and its impact on identity formation, in order to enhance human well-being. To give substance to this argument, Jenkins's model of social identity is appropriated and augmented to take account of four interlinked, yet distinct, orders of experience, namely the individual, interactional, institutional and societal orders. This reworked conceptualisation is then considered in terms of its implications for social work practice.

Predictors of academic achievement and social competence in adolescence : facilitation, inhibition and general cognitive processing /

The relevance of attentional measures to cognitive and social adaptive behaviour was examined in an adolescent sample. Unlike previous research, the influence of both inhibitory and facilitory aspects of attention were studied. In addition, contributions made by these attentional processes were compared with traditional psychometric measures of cognitive functioning. Data were gathered from 36 grade 10 and 1 1 high school students (20 male and 16 female students) with a variety of learning and attentional difficulties. Data collection was conducted in the course of two testing sessions. In the first session, students completed questionnaires regarding their medical history, and everyday behaviours (the Brock Adaptive Functioning Questionnaire), along with non-verbal problem solving tasks and motor speed tasks. In the second session, students performed working memory measures and computer-administered tasks assessing inhibitory and facilitory aspects of attention. Grades and teacher-rated measures of cognitive and social impulsivity were also gathered. Results indicate that attentional control has both cognitive and social/emotional implications. Performance on negative priming and facilitation trials from the Flanker task predicted grades in core courses, social functioning measures, and cognitive and social impulsivity ratings. However, beneficial effects for academic and social functioning associated with inhibition were less prevalent in those demonstrating a greater ability to respond to facilitory cues. There was also some evidence that high levels of facilitation were less beneficial to academic performance, and female students were more likely to exceed optimal levels of facilitory processing. Furthermore, lower negative priming was ''S'K 'i\':y-: -'*' - r " j«v ; ''*.' iij^y Inhibition, Facilitation and Social Competence 3 associated with classroom-rated distraction and hyperactivity, but the relationship between inhibition and social aspects of impulsivity was stronger for adolescents with learning or reading problems, and the relationship between inhibition and cognitive impulsivity was stronger for male students.

Construing social dimensions of personality development: nurses as educators

A convenience sample of twenty registered nurses was recruited from two' general hospitals and two community college nursing schools. Kelly's (1955) Personal Construct Theory provided the theoretical framework to discover how nurses perceived themselves as educators. The nurses completed a self-administered Self-Perception Inventory (Soares, 1983) to determine their perception of self as nurse and ideal self as nurse. In an interview, each of the nurses constructed a rank-order repertory grid adapted from Kelly's (1955) Role Repertory Construct Test. Twelve constructs derived from the Self-Perception Inventory (Soares, 1983) were ranked according to a list of ten elements common to a teaching situation. Rank order correlations among the constructs were determined with Spearman's rho. Using a dependent samples t-test, significant differences were found between perceptions of current and ideal self for staff nurses. Significant differences were also found between nurse educators' perceptions of self and ideal self as nurse. No significant differences were determined in perceptions of self as nurse and ideal self as nurse between the staff nurse and nurse educator groups with an independent samples t-test. However, observations of single constructs revealed that although several constructs are shared between the groups in the perception of self in a teaching situation, both groups hold constructs that operate exclusively in their separate domains. The nature and strength of the relationships between the common and unique constructs are different for each group. Nurses I self-perceptions appear to be influenced by the historical development of nursing, role socialization during nursing education, social expectations and gender issues in the health care system.
