With increasing age, there are greater numbers of older people who will be diagnosed with cancer. It must be remembered that such individuals have increased frailty and have a number of geriatric syndromes and conditions particularly pertinent to older age, including incontinence, poor cognition and impaired nutrition. It is often difficult to define the effects of cancer and its treatment or complications, and separate these from the effects of normal ageing and geriatric syndromes. The documentation of poor nutrition and its management must combine knowledge from both geriatric medicine and oncology. Nutrition serves to identify key healthcare professionals who are all essential in any patient at risk or suffering from malnutrition. Incontinence must be actively sought, its cause identified and efforts made to either 'cure' it or, in certain circumstances, 'manage' it. Older patients with cancer are cared for predominantly by older relations and informal care mechanisms and special consideration of their physical and practical needs are paramount. In this area, nurses, doctors, therapists and social workers should work to identify formal and informal mechanisms to support particularly the older carer.

The human mirror neuron system (hMNS) has been associated with various forms of social cognition and affective processing including vicarious experience. It has also been proposed that a faulty hMNS may underlie some of the deficits seen in the autism spectrum disorders (ASDs). In the present study we set out to investigate whether emotional facial expressions could modulate a putative EEG index of hMNS activation (mu suppression) and if so, would this differ according to the individual level of autistic traits [high versus low Autism Spectrum Quotient (AQ) score]. Participants were presented with 3 s films of actors opening and closing their hands (classic hMNS mu-suppression protocol) while simultaneously wearing happy, angry, or neutral expressions. Mu-suppression was measured in the alpha and low beta bands. The low AQ group displayed greater low beta event-related desynchronization (ERD) to both angry and neutral expressions. The high AQ group displayed greater low beta ERD to angry than to happy expressions. There was also significantly more low beta ERD to happy faces for the low than for the high AQ group. In conclusion, an interesting interaction between AQ group and emotional expression revealed that hMNS activation can be modulated by emotional facial expressions and that this is differentiated according to individual differences in the level of autistic traits. The EEG index of hMNS activation (mu suppression) seems to be a sensitive measure of the variability in facial processing in typically developing individuals with high and low self-reported traits of autism.

Three experiments examined the cultural relativity of emotion recognition using the visual search task. Caucasian-English and Japanese participants were required to search for an angry or happy discrepant face target against an array of competing distractor faces. Both cultural groups performed the task with displays that consisted of Caucasian and Japanese faces in order to investigate the effects of racial congruence on emotion detection performance. Under high perceptual load conditions, both cultural groups detected the happy face more efficiently than the angry face. When perceptual load was reduced such that target detection could be achieved by feature-matching, the English group continued to show a happiness advantage in search performance that was more strongly pronounced for other race faces. Japanese participants showed search time equivalence for happy and angry targets. Experiment 3 encouraged participants to adopt a perceptual based strategy for target detection by removing the term 'emotion' from the instructions. Whilst this manipulation did not alter the happiness advantage displayed by our English group, it reinstated it for our Japanese group, who showed a detection advantage for happiness only for other race faces. The results demonstrate cultural and linguistic modifiers on the perceptual saliency of the emotional signal and provide new converging evidence from cognitive psychology for the interactionist perspective on emotional expression recognition.

AbstractBackground Depression in adolescence is debilitating with high recurrence in adulthood, yet its pathophysiological mechanism remains enigmatic. To examine the interaction between emotion, cognition and treatment, functional brain responses to sad and happy distractors in an affective go/no-go task were explored before and after Cognitive Behavioural Therapy (CBT) in depressed female adolescents, and healthy participants. Methods Eighty-two Depressed and 24 healthy female adolescents, aged 12 to 17 years, performed a functional magnetic resonance imaging (fMRI) affective go/no-go task at baseline. Participants were instructed to withhold their responses upon seeing happy or sad words. Among these participants, 13 patients had CBT over approximately 30 weeks. These participants and 20 matched controls then repeated the task. Results At baseline, increased activation in response to happy relative to neutral distractors was observed in the orbitofrontal cortex in depressed patients which was normalized after CBT. No significant group differences were found behaviourally or in brain activation in response to sad distractors. Improvements in symptoms (mean: 9.31, 95% CI: 5.35-13.27) were related at trend-level to activation changes in orbitofrontal cortex. Limitations In the follow-up section, a limited number of post-CBT patients were recruited. Conclusions To our knowledge, this is the first fMRI study addressing the effect of CBT in adolescent depression. Although a bias toward negative information is widely accepted as a hallmark of depression, aberrant brain hyperactivity to positive distractors was found and normalised after CBT. Research, assessment and treatment focused on positive stimuli could be a future consideration. Moreover, a pathophysiological mechanism distinct from adult depression may be suggested and awaits further exploration.

Challenging behaviours may elicit negative emotional reactions and increase stress within care staff. The Leeds Attributional Coding System (LACS) was used to elicit spontaneous causal attributions of staff toward hypothetical clients with challenging behaviours. It was hypothesized that there would be relationships (1) between staff exposure to challenging behaviours and burnout, and (2) between staff cognitions and burnout. Using a cross-sectional correlational design, 41 care staff took part in a 10 minute interview about two vignettes depicting self-injurious behaviour. Staff also completed measures of demographic information and burnout. Participants made attributions toward self-injurious behaviour that were typically internal to the client, uncontrollable, unstable and specific.There was a significant association between number of clients cared for and emotional exhaustion and personal accomplishment. Staff who made fewer stable attributions had higher levels of burnout. There were no other relationships found between staff cognition and burnout. The LACS can be successfully employed in this context, and may have some benefits over other methods. Future research is required to explore the relationship between cognition and burnout.

While a growing number of small- and medium-sized enterprises (SMEs) are making use of coaching, little is known about the impact such coaching has within this sector. This study sought to identify the factors that influence managers' decision to engage with coaching, their perceptions of the coaching ‘journey’ and the kinds of benefits accruing from coaching: organisational, personal or both. As part of a mixed methods approach, a survey tool was developed based upon a range of relevant management competencies from the UK's Management Occupational Standards and responses analysed using importance-performance analysis, an approach first used in the marketing sector to evaluate customer satisfaction. Results indicate that coaching had a significant impact on personal attributes such as ‘Managing Self-Cognition’ and ‘Managing Self-Emotional’, whereas the impact on business-oriented attributes was weaker. Managers' choice of coaches with psychotherapeutic rather than non-psychotherapeutic backgrounds was also statistically significant. We conclude that even in the competitive business environment of SMEs, coaching was used as a largely personal, therapeutic intervention rather than to build business-oriented competencies.

Genre stratification and the mass media’s neutralization of the critique of ADHD: A sociology of knowledge perspective This study examines how the Swedish mass media has dealt with the opposition against the neuropsychiatric diagnosis ADHD (Attention Deficit Hyperactivity Disorder). Drawing on empirical data from eight of the largest newspapers in Sweden (n=778 articles) the study focuses on the scientific controversy of DAMP, 2000–2006. DAMP (Dysfunction in Attention, Motor Control and Perception) is a diagnostic term denoting difficulties similar to ADHD, and which was used in Sweden at the time of the controversy. The study uncovers the ideological role played by the mass media during the DAMP-controversy, and demonstrates the significance of genre. While the spokespersons for DAMP/ADHD were given exclusive and systematic access to the news genre, the forum of fact-production in the mass media, the critics of DAMP/ADHD were confined to arguing and expressing their opinions in the debate genre. Based on the various effects of genre differences a comprehensive analytical tool for the sociology of knowledge, called genre stratification, is developed in the study

Abstract In a case study about viewing habits in a Swedish audience I sampled 309 questionnaires; interviews with five focus group were conducted together with ten in-depth individual interviews discussing altogether fifteen favorite films exploring specific scenes of idiosyncratic relevance. The outcome supports claims about viewers as active and playful (cf. Höijer 1998, Frampton 2006, Hoover 2006, Plantinga 2009). In line with mediatization theory I also argue that spiritual meaning making takes place through mediated experiences and I support theories about fiction films as important sources for moral and spiritual reflection (Partridge 2004, Zillman 2005, Lynch 2007, Plantinga 2009). What Hjarvard calls the soft side of mediatization processes (2008) is illustrated showing adults experiencing enchantment through favorite films (Jerslev 2006, Partridge 2008, Klinger 2008, Oliver & Hartmann 2010). Vernacular meaning making embedded in everyday life and spectators dealing with fiction narratives such as Gladiator, Amelie from Montmartre or Avatar highlights the need for a more nuanced understanding of elevated cinematic experiences. The reported impact of specific movies is analyzed through theories where cognition and affect are central aspects of spectators’ engagements with a film (Tan 1996, Caroll 1999, Grodal 2009). Crucially important are theories of meaning-making where viewers’ detailed interpretation of specific scenes are embedded in high-level meaning-making where world view issues and spectators’ moral frameworks are activated (Zillman 2005, Andersson & Andersson 2005, Frampton 2006, Lynch 2007, Avila 2007, Axelson 2008, Plantinga 2009). Also results from a growing body of empirical oriented research in film studies are relevant with an interest in what happens with the flesh and blood spectator exposed to filmic narratives (Jerslev 2006, Klinger 2008, Barker 2009, Suckfüll 2010, Oliver & Hartmann 2010). Analyzing the qualitative results of my case study, I want to challenge the claim that the viewer has to suspend higher order reflective cognitive structures in order to experience suture (Butler & Palesh 2004). What I find in my empirical examples is responses related to spectators’ highest levels of mental activity, all anchored in the sensual-emotional apparatus (Grodal 2009). My outcome is in line with a growing number of empirical case studies which support conclusions that both thinking and behavior are affected by film watching (Marsh 2007, Sückfull 2010, Oliver & Hartmann 2010, Axelson forthcoming). The presentation contributes to a development of concepts which combines aesthetic, affective and cognitive components in an investigation of spectator’s moves from emotional evaluation of intra-text narration to extra-textual assessments, testing the narrative for larger significance in idiosyncratic ways (Bordwell & Thompson 1997, Marsh 2007, Johnston 2007, Bruun Vaage 2009, Axelson 2011). There are a several profitable concepts suggested to embrace the complex interplay between affects, cognition and emotions when individuals respond to fictional narratives. Robert K. Johnston label it “deepening gaze” (2007: 307) and “transformative viewing” (2007: 305). Philosopher Mitch Avila proposes “high cognition” (2007: 228) and Casper Thybjerg ”higher meaning” (2008: 60). Torben Grodal talks about “feelings of deep meaning” (Grodal 2009: 149). With a nod to Clifford Geertz, Craig Detweiler adopts “thick description” (2007: 47) as do Kutter Callaway altering it to ”thick interpretations” (Callaway 2013: 203). Frampton states it in a paradox; ”affective intelligence” (Frampton 2006: 166). As a result of the empirical investigation, inspired by Geertz, Detweiler & Callaway, I advocate thick viewing for capturing the viewing process of these specific moments of film experience when profound and intensified emotional interpretations take place. The author As a sociologist of religion, Tomas Axelsons research deals with people’s use of mediated narratives to make sense of reality in a society characterized by individualization, mediatization and pluralized world views. He explores uses of fiction film as a resource in every day life and he is currently finishing his three year project funded by the Swedish Research Council: Spectator engagement in film and utopian self-reflexivity.

O presente trabalho aborda a relação histórica entre o Homem e o Risco, com ênfase nas relações contemporâneas, passando pela Ética Empresarial e pela Governança Corporativa, que têm por objetivo disciplinar as relações do capital com base nos princípios de eqüidade, transparência e prestação de contas, além do respeito às leis, regulamentos, normas, tanto formais quanto informais ou de mercado, e os aspectos éticos intrínsecos e culminando com a Lei Sarbanes-Oxley. Mais do que aproximar o investimento da produção, esse conjunto alicerça a confiança mútua, tornando-se arena de negócios entre atraídos e atraentes, ou seja, investidores e empresas. Estabelece, também, uma oportunidade para as empresas aumentarem suas origens por ação direta do patrimônio líquido, não implicando, portanto, em ônus dissociado do retorno, premiando, sob vários enfoques, a rentabilidade com responsabilidade social e percepção dos outros públicos inerentes ao negócio - stakeholders.

The study has the purpose to check the existence of correlation between country image and attitude towards films from different countries. The study also had the objective of verify the predominance of one of the three components of attitude: affect, cognition and behavior towards films from different countries. In order to accomplish the objective, 310 self-administered questionnaires, of five different kinds, each one relating to one of the five counties studied (China, France, Iran, India and United States) were applied. In all of them a session referring to Brazilian¿s films was introduced. From the data collected, it was possible to conclude that there is correlation among country image and attitude toward films from China, France, Iran, India and USA. It is also possible to conclude that in low involvement situation with films, there seems not to be any difference between the affective and cognitive means and the affective and behavioral means. Nevertheless, in high involvement situations with films, it was possible to verify a significant difference between cognitive and behavioral means, but not between cognitive and affective means. Based on the answers obtained from the sample studied, there is no significant difference between the means of the affective and the cognitive component and the affective and behavioral component of attitudes towards films, in situations of high involvement with the country of origin of the film. Finally, it was possible to conclude, from the sample studied that Brazilian¿s students seems to be more favorable to Brazilian films than to films from China, Iran, India and France and only north-american films seems to be seen by the students, as more favorable than Brazilian films.

Este trabalho procura justapor duas visões do homem no mundo, a cartesiana e a zen-budista, ressaltando o aspecto fragmentador da primeira e o aspecto integrador da segunda. O objetivo básico é contribuir para maior articulação e integração do homem contemporâneo através de três movimentos. Primeiro, através da critica à concepçao racionalista, mecânica, prepotente e antinatural, fundada na lógica dual e antitética do paradigma da ciência e do pensamento ocidental em boa parte construido por René Descartes; Segundo, através da divulgação e da exposição enfática, em nosso meio acadêmico ocidental, da metafisica e da mística budistas, especialmente em sua versão Zen, que compreende o mundo em permanente transformação e construção como um todo articulado ao equilibrio universal, no qual as palavras, os conhecimentos e a percepção são meros signos passageiros que escondem a realidade cósmica. O movimento final pretende negar uma visão maniqueísta da realidade onde a oposição não é vista como a liquidação de um dos termos pelo outro, mas como a busca de uma nova síntese: a gestação, enfim, de um novo referencial do mundo - e aqui apenas se levanta a questão - a ser construído, quem sabe, a partir da integração dos paradigmas caracterizados hoje como ocidental e oriental.

O presente trabalho constitui uma tentativa de exploração dos aspectos psicológicos inerentes ao processo de controle social, segundo a perspectiva da "análise experimental do comportamento" de B. F. Skinner. Diversas proposições sociológicas correntes sobre algumas dimensões do problema geral são levantadas e criticamente articuladas com a abordagem comportamental skinneriana. No primeiro capítulo - "O Controle Social nas Instituições Totais”, é feita uma introdução conceitual ao condicionamento operante aproveitando-se para isso a descrição sociológica realizada por Goffman da vida naquelas instituições, são também aí discutidas algumas das interpretações erroneas das proposições skinnerianas e seus maus usos nas organizações fechadas. Desenvolve-se, no segundo capítulo, um exame comparativo das ficções literárias de "1984 “ e "Walden II", com o propósito de pela focalização de suas técnicas características de controle social, suscitar já, de modo informal, diversos pontos críticos do problema, que vêm a receber tratamento mais pormenorizado nos três capítulos seguintes. Em "Controle Social na Vida Cotidiana", discute-se a natureza difusa que o controle assume nesse contexto mais amplo, ressaltando-se o emprego que se faz, para esse fim, de artifícios motivacionais e ideológicos. Para a articulação com o pensamento skinneriano, é privilegiada abordagem da Sociologia do Conhecimento proposta por Berger e Luckmann. No quarto capítulo, que trata da "Identificação de Controladores e Controlados", procede-se a uma reinterpretação comportamentista dos constructos cognitivistas de “intenção” e "percepção”, com que comumente se descreve as iniciativas de controle por parte dos atores sociais. A análise de Becker dos mecanismos de criação e imposição de regras é utilizada par a apoiar a estratégia de reinterpretação. O capítulo final explora uma dimensão menos tradicional do problema - "O Controle para a Mudança Social". As proposições específicas de dois autores Popper e Mannheim - são aqui articuladas com as de Skinner. Caracterizado o estado da sociedade contemporânea como de incessante mudança desordenada, discute-se as condições necessárias para uma mudança planejada e suas implicações psicossociais. Na conclusão do trabalho, busca-se ampliar a perspectiva histórica do problema do controle social, por meio de uma análise retrospectiva proporcionada por Schneider e uma especulação prospectiva envolvendo a apreciação sócio- política do controle gradualista e democrático da mudança social. Defende-se, durante essa apreciação, a tese de que a engenharia comportamental de Skinner é gradualista e democrática em seu todo.

O cenário atual das organizações revela importantes mudanças. A análise de seus resultados mercadológicos está sendo realizada de um modo bastante diferente de tempos atrás. Hoje a avaliação das empresas necessita ultrapassar seus resultados quantitativos. Com isso, as corporações buscam ferramentas para mensurar variáveis qualitativas: desejam saber de sua credibilidade, sua imagem e a percepção de seu posicionamento mercadológico. Neste contexto, o objetivo do presente estudo é identificar e analisar os formatos de avaliação que são utilizados pelas empresas para mensurar a efetividade dos resultados qualitativos da organização na perspectiva dos conceitos de reconhecimento, reputação, impressão, identidade empresarial, imagem, qualidade e satisfação. Na análise das evidências coletadas na empresa estudo de caso foi identificado que os processos do planejamento estratégico e a sua vinculação a um programa de qualidade, com seu respectivo processo de avaliação, são os principais parâmetros para mensurar os resultados qualitativos. Estes critérios e análises, juntamente com o controle e acompanhamento das metas e indicadores oriundos do planejamento estratégico, são os orientadores do processo de avaliação dos resultados desta empresa.

A sonoridade é um aspecto importante para a execução violonística. Esse trabalho tem por objetivo estudar a sonoridade com um elemento da execução musical, entender os seus aspectos formadores dentro do âmbito técnico, textual e perceptivo, utilizando-se como exemplo duas gravações das Quatro Peças Breves de Frank Martin. Os resultado são discutidos à luz do embasamento teórico, fazendo-se considerações a respeito das possibilidades de execução musical e como a sonoridade do violão atua nesse contexto.
