In three experiments we investigated the impact that exposure to counter-stereotypes has on emotional reactions to outgroups. In Experiment 1, thinking about gender counter-stereotypes attenuated stereotyped emotions toward females and males. In Experiment 2, an immigrant counterstereotype attenuated stereotyped emotions toward this outgroup and reduced dehumanization tendencies. Experiment 3 replicated these results using an alternative measure of humanization. In both Experiments 2 and 3 sequential meditational analysis revealed that counter-stereotypes produced feelings of surprise which, in turn, elicited a cognitive process of expectancy violation which resulted in attenuated stereotyped emotions and an enhanced use of uniquely human characteristics to describe the outgroup. The findings extend research supporting the usefulness of counter-stereotype exposure for reducing prejudice and highlight its positive impact on intergroup emotions.

Identity influences the practice of English language teachers and supervisors, their professional development and their ability to incorporate innovation and change. Talk during post observation feedback meetings provides participants with opportunities to articulate, construct, verify, contest and negotiate identities, processes which often engender issues of face. This study examines the construction and negotiation of identity and face in post observation feedback meetings between in-service English language teachers and supervisors at a tertiary institution in the United Arab Emirates. Within a linguistic ethnography framework, this study combined linguistic microanalysis of audio recorded feedback meetings with ethnographic data gathered from participant researcher knowledge, pre-analysis interviews and post-analysis participant interpretation interviews. Through a detailed, empirical description of situated ‘real life’ institutional talk, this study shows that supervisors construct identities involving authority, power, expertise, knowledge and experience while teachers index identities involving experience, knowledge and reflection. As well as these positive valued identities, other negative, disvalued identities are constructed. Identities are shown to be discursively claimed, verified, contested and negotiated through linguistic actions. This study also shows a link between identity and face. Analysis demonstrates that identity claims verified by an interactional partner can lead to face maintenance or support. However, a contested identity claim can lead to face threat which is usually managed by facework. Face, like identity, is found to be interactionally achieved and endogenous to situated discourse. Teachers and supervisors frequently risk face threat to protect their own identities, to contest their interactional partner’s identities or to achieve the feedback meeting goal i.e. improved teaching. Both identity and face are found to be consequential to feedback talk and therefore influence teacher development, teacher/supervisor relationships and the acceptance of feedback. Analysis highlights the evaluative and conforming nature of feedback in this context which may be hindering opportunities for teacher development.

Since 1963 Cuba has provided medical assistance to third world countries while gaining international, political and economic support from its participating liaisons. But what exactly have been Cuba’s domestic consequences of such medical diplomacy? While the Cuban government sends many of its medical professionals and supplies abroad, the country suffers from extreme scarcity and a deterioration of its healthcare system. The purpose of my research is to enquire more on the consequences of such medical diplomacy on the Cuban healthcare system and how it has affected domestic medical infrastructure, health professionals working on the island as well as the quality of service. In carrying out this examination, I will rely on the use of information from books written by Cuban medical professionals on their personal experiences within the medical system, and patients treated on the island. I will also make active use of academic journals and articles on the Cuban healthcare system. Most of what has been written on Cuban medical diplomacy and internationalist missions are favorable critiques praising the Cuban government. Nevertheless, personal testimonies found in Dr. Dessy Mendoza Rivero’s Dengue: La Epidemia Secreta de Fidel Castro and in Dr. Jose Luis Comas and Dr. Luis Ovidio Gonzales’ Cuba: Medicina y Revolucion reveal a different side to this seemingly pleasant and good natured international exchange. As a Cuban who lived on the island, I personally suffered the consequences of such medical diplomacy and believe others will find benefit in arming themselves with knowledge on the issue.

Emotion-based analysis has raised a lot of interest, particularly in areas such as forensics, medicine, music, psychology, and human-machine interface. Following this trend, the use of facial analysis (either automatic or human-based) is the most common subject to be investigated once this type of data can easily be collected and is well accepted in the literature as a metric for inference of emotional states. Despite this popularity, due to several constraints found in real world scenarios (e.g. lightning, complex backgrounds, facial hair and so on), automatically obtaining affective information from face accurately is a very challenging accomplishment. This work presents a framework which aims to analyse emotional experiences through naturally generated facial expressions. Our main contribution is a new 4-dimensional model to describe emotional experiences in terms of appraisal, facial expressions, mood, and subjective experiences. In addition, we present an experiment using a new protocol proposed to obtain spontaneous emotional reactions. The results have suggested that the initial emotional state described by the participants of the experiment was different from that described after the exposure to the eliciting stimulus, thus showing that the used stimuli were capable of inducing the expected emotional states in most individuals. Moreover, our results pointed out that spontaneous facial reactions to emotions are very different from those in prototypic expressions due to the lack of expressiveness in the latter.

Este estudo trata da comunicação face a face nas organizações sob diferentes abordagens teóricas. Considera a perspectiva da simultaneidade dos meios, já que as empresas utilizam diversos canais para dialogar com seus públicos de interesse. Leva em conta o fenômeno da midiatização, que reestrutura o modo como as pessoas se relacionam na sociedade contemporânea. O objetivo geral da pesquisa é sistematizar papeis potencialmente exercidos pela interação face a face e conhecer algumas circunstâncias que envolvem sua prática nas organizações. Por se tratar de uma tese teórica, a pesquisa bibliográfica se apresenta como um dos principais procedimentos metodológicos; análises de casos empíricos e um estudo de caso desenvolvido na Embrapa Pantanal constituem situações ilustrativas. Conclui-se que a comunicação face a face nas empresas ocorre de forma simultânea e combinada a outros canais de comunicação, porém, ela proporciona resultados práticos e filosóficos ainda pouco explorados. É rara a utilização estratégica de contatos presenciais como mecanismo para estabelecer relacionamentos, conhecer as reações alheias e ajustar a comunicação, aliar o discurso corporativo às práticas empresariais e avaliar o contexto onde se desenvolvem as interações, o que pode ser decisivo para a comunicação organizacional.

The relationship between uncertainty and firms’ risk-taking behaviour has been a focus of investigation since early discussion of the nature of enterprise activity. Here, we focus on how firms’ perceptions of environmental uncertainty and their perceptions of the risks involved impact on their willingness to undertake green innovation. Analysis is based on a cross-sectional survey of UK food companies undertaken in 2008. The results reinforce the relationship between perceived environmental uncertainty and perceived innovation risk and emphasise the importance of macro-uncertainty in shaping firms’ willingness to undertake green innovation. The perceived (market-related) riskiness of innovation also positively influences the probability of innovating, suggesting either a proactive approach to stimulating market disruption or an opportunistic approach to innovation leadership.

This paper synthesizes and discusses the spatial and temporal patterns of archaeological sites in Ireland, spanning the Neolithic period and the Bronze Age transition (4300–1900 cal BC), in order to explore the timing and implications of the main changes that occurred in the archaeological record of that period. Large amounts of new data are sourced from unpublished developer-led excavations and combined with national archives, published excavations and online databases. Bayesian radiocarbon models and context- and sample-sensitive summed radiocarbon probabilities are used to examine the dataset. The study captures the scale and timing of the initial expansion of Early Neolithic settlement and the ensuing attenuation of all such activity—an apparent boom-and-bust cycle. The Late Neolithic and Chalcolithic periods are characterised by a resurgence and diversification of activity. Contextualisation and spatial analysis of radiocarbon data reveals finer-scale patterning than is usually possible with summed-probability approaches: the boom-and-bust models of prehistoric populations may, in fact, be a misinterpretation of more subtle demographic changes occurring at the same time as cultural change and attendant differences in the archaeological record.

[EN]In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditional face detection making it particularly interesting for surveillance. The performance of the proposed detector in terms of accuracy and speed is evaluated on data sets from PETS 2000 and PETS 2003 and compared to the object-centered approach. Particular attention is paid to the role of available image resolution.

O presente estudo teve como objectivo principal conhecer melhor aspectos relacionados com a sexualidade na 3ª idade. A escala utilizada foi construída por nós, tornando-se num elemento chave para esta pesquisa. A escala de atitudes face à sexualidade no idoso foi relacionada com algumas características sociodemográficas: género, idade, estado civil, escolaridade e religião. Da análise realizada ressaltam evidências de uma atitude conservadora face às questões da sexualidade na 3ª idade. Através de uma amostra de 120 idosos com idades compreendidas entre os 60 e os 97 anos de idade, constatámos que os homens e as mulheres distinguem-se significativamente no que respeita às atitudes face à sexualidade, exibindo os homens uma atitude global mais positiva e liberal (M = 25.82). Os resultados evidenciaram um efeito significativo da variável escolaridade sobre o nível cognitivo, revelando que quanto maior a escolaridade do idoso na nossa amostra, maior é o nível cognitivo. Relativamente ao estado civil, os casados revelaram uma atitude global mais positiva perante a sua sexualidade (M = 31.98) comparativamente aos viúvos (M = 27.26) e aos divorciados (M = 23.67). A religião apenas se mostrou associada com a escala de atitudes face ao cristianismo, evidenciando aqueles que são praticantes, uma atitude mais positiva em relação ao cristianismo. Na nossa amostra, também podémos constatar que quanto maior é o nível cognitivo, mais positiva é a atitude face à sexualidade. Com base nos pontos de corte do MMSE verificou-se que 75% dos idosos da nossa amostra não apresentava qualquer défice cognitivo. Comparados os grupos, sem e com défice cognitivo, constatou-se que o grupo de idosos sem défice cognitivo exibe uma atitude mais positiva face à sexualidade que o grupo com défice cognitivo. Pretendemos que de alguma forma este estudo contribua para dar a conhecer as atitudes dos idosos face à sua sexualidade bem como esperamos que os nossos resultados permitam uma reflexão sobre possíveis estratégias de intervenção no sentido de promover uma sexualidade bem vivida por esta faixa etária. / The present study aimed to better understand the main aspects related to sexuality in the 3rd age. The scale used was built by us, becoming a key element in this research. The scale of attitudes towards sexuality in the elderly was related to sociodemographic characteristics: gender, age, marital status, education and religion. From the analysis point out evidence of a conservative approach in relation to issues of sexuality in the 3rd age. Using a sample of 120 elderly aged 60 and 97 years old, found that men and women differ significantly with regard to attitudes towards sexuality, men showing a more positive overall attitude and liberal (M = 25.82). The results showed a significant effect on the education variable cognitive level, revealing that the higher the education of the elderly in our sample, the higher the cognitive level. With regard to marital status, married people showed a more positive overall attitude towards their sexuality (M = 31.98) compared to widowed (M = 27.26) and divorced (M = 23.67). The only religion was associated with the scale of attitudes to Christianity, showing those who are practitioners, a more positive attitude toward Christianity. In our sample, we can also see that the higher the cognitive level, the more positive attitude towards sexuality. Based on the MMSE cutoffs found that 75% of older people in our sample did not show any cognitive deficit. Comparing the groups with and without cognitive impairment, it was found that the group of elderly people without cognitive impairment display a more positive attitude towards sexuality that the group with cognitive impairment. We intend that somehow this study contributes to publicize the attitudes of the elderly compared to their sexuality and we expect our results allow a discussion on possible intervention strategies to promote a sexuality lived well by this age group.

Ao longo dos últimos anos, a homossexualidade tem sido tema de diversos estudos com destaque para os domínios da homoparentalidade. No mesmo contexto, alguns investigadores têm-se preocupado com questões relacionadas com adoção de crianças por casais homossexuais. O presente estudo pretendeu particularmente conhecer os níveis de Aceitação/Rejeição por parte de estudantes do ensino superior quanto à adoção de crianças por casais homossexuais. Realizou-se um estudo com uma amostra não-probabilística, através dum questionário online em que participaram 695 indivíduos, sendo 215 do sexo masculino (30.9%) e 477 do sexo feminino (68.6%), com idades de 17 a 60 anos. A recolha de dados foi feita através de Questionário Sociodemográfico; a EAACH – Escala de Atitudes Face à Adoção de Crianças por Homossexuais, a EEH – Escala de Explicações da Homossexualidade, a ERP – Escala de Rejeição à Proximidade/Intimidade, a EEE – Escala de Expressão Emocional. Os resultados apontam para uma diferença significativa em favor do fator aceitação, sendo que quanto maior a idade, menor é a aceitação da adoção por casais homossexuais. Quanto à explicação da homossexualidade, os sujeitos de menor idade tendem a associa-la a fatores psicossociais, enquanto os mais velhos relevam explicações sobretudo do foro ético-moral e religioso. Verificamos ainda que o género feminino revela atitudes de maior tolerância e aceitação, do mesmo modo que os divorciados/ separados. Verificamos igualmente que a crença em Deus e o grau de religiosidade se relacionam com a menor aceitação da adoção por casais homossexuais. As conclusões resultantes dos nossos dados vão ao encontro da generalidade dos estudos sobre o tema, permitindo constatar que as atitudes que têm permitido manter a ideia de que mulheres lésbicas e homens gays não têm competências parentais que permitam a adequada educação de crianças e adolescentes, serão consequência de preconceitos ainda instalados. Pensamos, no entanto, que é injusto e mesmo imoral que se negue a possibilidade a muitas crianças de serem amadas e educadas por quem tem condições de as amar e educar.

A problemática do envelhecimento tem assumido, nos últimos anos, uma crescente importância na consciência coletiva da população, tornando-se cada vez mais importante compreender a população idosa e a sua realidade. Posto isto, foi realizado um estudo quantitativo e correlacional, que teve como objectivo avaliar a qualidade de vida e atitudes face à velhice de idosos, bem como a relação entre estas e as variáveis sociodemográficas e familiares. Foram inquiridos 100 idosos, com mais de 65 anos e sem deficit cognitivo . Para a recolha de dados utilizou-se uma entrevista estruturada, constituída dados sóciodemográficos do idoso, WHOQOL-AGE (Caballero, Miret, Power, Chatterji, Tobiasz-Adamczyk, Koskinen, Leonardi, Olaya, Haro &Ayuso-Mateos, 2013) e o AAQ ( Laidlaw, Power, Schmidt and the WHOQOL-OLD Group, 2007). Dos resultados destacamos os seguintes: A amostra é constituída por 52% de idosos do sexo masculino tendo uma média de idades de 74,7 (DP=6,8). È no fator Perdas Psicossociais e no Desenvolvimento Psicológico que os idosos têm uma melhor atitude face ao envelhecimento. É no item “Tem dinheiro suficiente para satisfazer as suas necessidades?” que os idosos apresentam uma menor qualidade de vida. Não ter doença diagnosticada e ser do sexo masculino permitem ter melhores atitudes face ao envelhecimento. A Qualidade de Vida está relacionada com a idade, com o estado de saúde e com a intensidade de preocupação da família. Constatou-se que os idosos que não estão institucionalizados apresentam uma melhor qualidade de vida e uma melhor atitude face à velhice. Quem não precisa de ajudas técnicas para se movimentar apresenta uma melhor qualidade de vida. Diferenças nas atitudes face ao envelhecimento consoante a residência onde habita são significativas nas mudanças físicas e no desenvolvimento psicológico sendo que os idosos que não vivem em lares têm uma atitude mais positiva em ambos os fatores. / Over the past few years the issue of aging has played a growing importance in the population`s collective consciousness becoming increasingly important to understand the elderly population and this reality. Therefore a quantitative correlational study was performed to assess the quality of life of seniors and their attitudes towards old age, and the relationship between these and the socio-demographic and family factors. 100 seniors with more than 65 years and without cognitive deficit were surveyed. For data collection we used a structured interview consisting of sociodemographic data of the elderly, WHOQOL-AGE (Caballero Miret Power Chatterji Tobiasz-Adamczyk Koskinen Leonardi Olaya Ayuso-Mateos & Haro 2013) and AAQ (Laidlaw Power Schmidt and the WHOQOL-OLD Group 2007). We highlight: The sample is composed of 52% of males with a mean age of 74.7 (SD = 6.8). It is in the factor Psychosocial Losses and Psychological Development that elderly people have a better attitude towards aging. It is in the item "Do you have enough money to meet your needs?" that seniors show less quality of life. Not having illness and being male allows having better attitudes towards aging. Quality of Life is related to age, health condition and the intensity of family concerns. It was observed that the elderly who are not institutionalized have a better quality of life and a better attitude towards old age. Who does not need assistive devices to move around has a better quality of life. Differences in attitudes towards aging, according to residency, are significant in physical changes and psychological development, thus verifying that elderly who do not live in nursing homes have a more positive attitude in both factors.

Ce mémoire trouve son origine dans le questionnement que nous avons posé par rapport à nos propres représentations concernant la pratique de l’art lorsque nous avons pris connaissance du plan d’action Québec horizon culture et en particulier du programme de mentorat qu’il offre aux artistes et qui consistent à les jumeler avec des gens d’affaires. Dans ce mémoire, nous avons cherché à comprendre comment les individus qui aspirent à faire de l’art subissent les injonctions du milieu artistique et les valeurs qu’il véhicule, de même que les exigences à propos de l’art véhiculées plus généralement dans la société. Notre intérêt s’est porté sur les représentations endossées par les artistes en lien avec la façon de subvenir à leurs besoins matériels. Plus particulièrement, nous avons cherché à savoir comment les programmes de mentorat auxquels prennent part des artistes participent de cet agencement et si les artistes qui manifestent de l’intérêt pour ces programmes ont une façon différente des autres d’envisager cet agencement. Pour répondre à ce questionnement, nous avons interrogé par des entretiens semi-dirigés des praticiens de l’art mentorés et non mentorés provenant de différents milieux artistiques. Il résulte de notre enquête qu’ils n’accordent pas tous la même place à l’activité artistique dans leur vie et que seulement certains cherchent à subvenir à leurs besoins matériels par l’activité artistique. De ces deux dimensions de la pratique artistique, nous avons conclu que le sens de la pratique artistique varie d’un répondant à l’autre. Nous avons finalement dégagé quatre types de finalité de la pratique artistique : intégrée, récréative, désintéressée et instrumentale.
