Reply to: punishing food: what brain activity can tell us about the representation of food in recovered anorexia nervosa

Eating disorders are characterized by aberrant cognitions and behaviors around food. We used a novel functional magnetic resonance imaging task in a sample of recovered anorexia nervosa subjects to study the neural response to both pleasant and aversive food tastes and pictures compared with a group of matched female subjects who had never had the disorder. We report that individuals recovered from anorexia nervosa have an increased neural response to rewarding and aversive food stimuli, in the form of chocolate (e.g., in the ventral striatum) and moldy strawberries (e.g., in the caudate).

Self-licensing and financial rewards: is morality for sale?

This paper studies the impact of financially rewarding good deeds on self-licensing. We run a between-subjects experiment comprised of an adapted dictator game preceded by paid and unpaid pro-environmental tasks. We find that prefacing the dictator game with an unpaid good deed seems to establish a 'moral rectitude' which licenses subsequent selfish behaviour, whereas a paid good deed dampens this effect. Interestingly, the nature of the initial task has more of an effect on the binary option (give vs. not give) than on the amount donated.

University teaching: recognition and reward

Teaching in universities has increased in importance in recent years which, in part, is a consequence of the change in funding of universities from block grants to student tuition fees. Various initiatives have been made which serve to raise the profile of teaching and give it greater recognition. It is also important that teaching is recognised even more fully and widely, and crucially that it is rewarded accordingly. We propose a mechanism for recognising and rewarding university teaching that is based on a review process that is supported by documented evidence whose outcomes can be fed into performance and development reviews, and used to inform decisions about reward and promotion, as well as the review of probationary status where appropriate.

What are the limitations on the wider therapeutic use of phage?

Bacterial resistance to antibiotics poses a serious health threat. Since research into new antibiotics is not progressing at the same rate as the development of bacterial resistance, widespread calls for alternatives to antibiotics have been made. Phage therapy is an ideal alternative candidate to be investigated. However the success of phage therapy may be hampered by a lack of investment support from large pharmaceutical companies, due to their narrow spectrum of activity in antibiotics, very large costs associated with clinical trials of the variety of phages needed, and regulatory requirements remaining unclear. Intellectual property is difficult to secure for therapeutic phage products for a variety of reasons, and patenting procedures vary widely between the US and the EU. Consequently, companies are more likely to invest in phage products for decontamination or veterinary use, rather than clinical use in humans. Some still raise questions as to the safety of phage therapy overall, suggesting the possibility of cytotoxicity and immunogenicity, depending on the phage preparation and route. On the other hand, with patients dying because of infections untreatable with conventional antibiotics, the question arises as to whether it is ethical not to pursue phage therapy more diligently. A paradigm shift about how phage therapy is perceived is required, as well as more rigorous proof of efficacy in the form of clinical trials of existing medicinal phage products. Phage therapy potential may be fulfilled in the meantime by allowing individual preparations to be used on a named-patient basis, with extensive monitoring and multidisciplinary team input. The National Health Service and academia have a role in carrying out clinical phage research, which would be beneficial to public health, but not necessarily financially rewarding.

Enhanced neural response to anticipation, effort and consummation of reward and aversion during Bupropion treatment

Background We have previously shown that the selective serotonergic re-uptake inhibitor, citalopram, reduces the neural response to reward and aversion in healthy volunteers. We suggest that this inhibitory effect might underlie the emotional blunting reported by patients on these medications. Bupropion is a dopaminergic and noradrenergic re-uptake inhibitor and has been suggested to have more therapeutic effects on reward-related deficits. However, how bupropion affects the neural responses to reward and aversion is unclear. Methods 17 healthy volunteers (9 female, 8 male) received 7 days of bupropion (150 mg/day) and 7 days of placebo treatment, in a double-blind crossover design. Our functional Magnetic Resonance Imaging task consisted of 3 phases; an anticipatory phase (pleasant or unpleasant cue), an effort phase (button presses to achieve a pleasant taste or to avoid an unpleasant taste) and a consummatory phase (pleasant or unpleasant tastes). Volunteers also rated wanting, pleasantness and intensity of the tastes. Results Relative to placebo, bupropion increased activity during the anticipation phase in the ventral medial prefrontal cortex (vmPFC) and caudate. During the effort phase, bupropion increased activity in the vmPFC, striatum, dorsal anterior cingulate cortex and primary motor cortex. Bupropion also increased medial orbitofrontal cortex, amygdala and ventral striatum activity during the consummatory phase. Conclusions Our results are the first to show that bupropion can increase neural responses during the anticipation, effort and consummation of rewarding and aversive stimuli. This supports the notion that bupropion might be beneficial for depressed patients with reward-related deficits and blunted affect.

Negative anticipatory contrast: Does it involve anticipation of an impending reward?

Negative anticipatory contrast (NAC) corresponds to the suppression in consumption of a first rewarding substance (e.g., saccharin 0.15%) when it is followed daily by a second preferred substance (e.g., sucrose 32%). The NAC has been interpreted as resulting from anticipation of the impending preferred reward and its comparison with the currently available first reward [Flaherty, CF., Rowan, G.A., 1985. Anticipatory contrast: within-subjects analysis. Anim. Learn. Behav. 13, 2-5]. In this context, one should expect that devaluation of the preferred substance after the establishment of the NAC would either reduce or abolish the contrast effect. However, contrary to this prediction, the results of the present study show that the NAC is insensitive to devaluation of the second, preferred, substance. This allows one to question that interpretation. The results reported in this study support the view that the NAC effect is controlled by memory of the relative value of the first solution, which is updated daily by means of both a gustatory and/or post-ingestive comparison of the first and second solutions, and memory of past pairings.

The periaqueductal gray and its potential role in maternal behavior inhibition in response to predatory threats

Animals faced with conflicting cues, such as predatory threat and a given rewarding stimulus, must make rapid decisions to engage in defensive versus other appetitive behaviors. The brain mechanisms mediating such responses are poorly understood. However, the periaqueductal gray (PAG) seems particularly suitable for accomplishing this task. The PAG is thought to have, at least, two distinct general roles on the organization of motivated responses, i.e., one on the execution of defensive and reproductive behaviors, and the other on the motivational drive underlying adaptive responses. We have presently examined how the PAG would be involved in mediating the behavioral choice between mutually incompatible behaviors, such as reproduction or defense, when dams are exposed to pups and cat odor. First, we established the behavioral protocol and observed that lactating rats, simultaneously exposed to pups and cat odor, inhibited maternal behavior and expressed clear defensive responses. We have further revealed that cat odor exposure up-regulated Fos expression in the dorsal PAG, and that NMDA cytotoxic lesions therein were able to restore maternal responses, and, at the same time, block defensive responsiveness to cat odor. Potential paths mediating the dorsal PAG influences on the inhibition of appetitive (i.e., retrieving behavior) and consummatory (i.e., nursing) maternal responses are discussed. Overall, we were able to confirm the dual role of the PAG, where, in the present case, the dorsal PAG, apart from organizing defensive responses, also appears to account for the behavioral inhibition of non-defensive responses.

The Construction of Identity in Edwidge Danticat's The Farming of Bones

The Farming of Bones deals with issues surrounding the dynamic connections between identity and boundary construction in post-colonial context. It will present an analysis of how the novelist problematizes and communicates her idea of social and national identity construction to her readers and how the readers can identify themselves with the struggles and challenges of the protagonist Amabelle who is trying to find her own identity. This essay will show how Danticat’s novel contributes to an understanding of national identity beyond borders and makes the reader take the role of an individual who constructs her identity by uncovering moments of raw humanness. Until now, no literary scholar has examined the protagonist’s therapeutic role in bridging this social and national gap. Instead critics have discussed other issues of the novel like crossing and re-crossing the border, love, dreams, etc. Although this scholarship has been very effective and rewarding, it lacks any focus on the complexity of the characters’ identity construction. Therefore, this paper will reconsider Danticat’s The Farming of Bones with a closer attention to the question of identity.

Online and Offline Gaming as Support for English Education in Swedish Upper Elementary Schools with Focus on Reading Comprehension Online and Offline Gaming as Support for English Education in Swedish Upper Elementary Schools with Focus on Reading Comprehension : A literature review about online and offline gaming as a resource for developing English reading comprehension in Swedish schools in year 4-6

The aim of this degree thesis is to see what research says about the use of computer and video games to support upper elementary pupils’ development in English reading comprehension in Swedish schools. Other goals are to see how online and offline gaming can be integrated in the Swedish schools and what attitudes teachers have towards gaming. The method used is a systematic literature review and the purpose is to analyze chosen articles and to find relevant content that answers the research questions. Five articles were chosen from different databases and were systematically analyzed in this thesis. The results show that online gaming as support for education can be rewarding for some upper elementary pupils in English learning. However, in English reading comprehension there is not much research found which means that more research needs to be made within this area. Moreover, involving online gaming in English language learning seems to be a challenge for teachers mostly because of their lack of knowledge about the subject, even though they are positive to gaming. The lack of knowledge about the subject could be altered with more education and courses in the area.

Primitive art as it relates to contemporary design

For the most part, my project has been of an individually rewarding nature due to an extensive amount of reading and studio work. My paper functions as the major means of communication of my own experiences and findings. It is an attempt to share with others the ideas which I have found particularly stimulating and worthwhile during the course of the year. In other words, the written portion does not intend to summarize all of the phases of primitive art which I have studied during the past year; rather, it is indicative of the type of pursuit with which I became involved. It is neither a historical survey nor a specific and thorough study of one area of primitive art. Instead, my paper is a series of essays focusing upon primitive art in general, and upon some of the aspects of primitive art with which I became concerned in particular.

Sculptural abstraction of landscape

The purpose of my Senior Scholar project was to create a series of sculptures that are based on the interaction of natural forms within a selected landscape setting. I hope to convey a sense of how I view and interpret the landscape and to create works that stimulate a sense of wonder in the mind of the viewer. This fascination, perhaps even obsession, with the power of the landscape has kept me going throughout the year. As a source of ideas and imagery, the landscape can never be depleted. There will always be new combinations of landscape elements, different light conditions, and changing seasons to provide me with fresh ideas. Research for the project took me to many different places, be it my trip to Monhegan Island or driving to New York City to study the cityscape. I began the year working in steel and plaster, combining the two in works that explore the interaction between living tree roots and inanimate rocks. This led to a series entitled Landscape Recollections, comprised of welded steel forms housed in protective wooden boxes and lit from inside. After visiting New York City, architecture began to playa role in my work, as seen in the two Roadcut pieces and the Cathedral Woods series. Roadcut #1 and Roadcut #2 explore the relationship between a man-made road and the landscape that lies beneath and around it. The Cathedral Woods pieces incorporate architecture in a more abstract manner, using imagery derived from Gothic cathedrals to convey a sense of quiet peacefulness. The soaring verticality of Gothic architecture integrates with the tall tree forms in each piece, enabling me to intertwine these two elements into one another and create a harmonious relationship between architecture and nature. Throughout the year I have kept a sketchbook in which I draw from life, jot down ideas, and take notes on how the project is progressing. I have also completed several large charcoal drawings of my sculptures in which I explore different ways of viewing the steel forms. I am grateful to have had the opportunity to undertake this project, as it has been a very difficult but rewarding process of observing, interpreting, and manifesting the landscape according to my personal vision and experiences.

Motivação para o trabalho como fator de produtividade e criatividade em empresas de médio porte - o caso ACEPLAC

O propósito primeiro desta dissertação foi o de mostrar, por meio de um estudo de caso, o da ACEPLAC, a aplicação do conceito de motivação como fator de criatividade e incremento de produção, em empresas de médio porte, sustentado por um modelo de gestão e de projetos de recompensa. Buscou-se justificar tal modelo pela observação sistemática dos esforços de trabalho, que se mostraram capazes de manter a motivação organizacional, apesar de sua volatilidade e voluntariedade. O método visava a trazer a experiência no campo concreto para o campo do conhecimento. Para isto, dividiu-se o longo processo em passos distintos, em que a obtenção de um arcabouço teórico sobre o complexo fenômeno que representa a motivação para o trabalho revelou-se o inequívoco ponto de partida. O estudo das várias características desse fenômeno e das inúmeras contribuições apresentadas desde Elton Mayo e Mary Follet até os dias atuais permitiu a construção de instrumental seguro para a análise crítica da realidade observada. Fez-se a opção de desenvolver a análise por meio do estudo de caso selecionado, uma vez que se pretendia ligar as abordagens teóricas à prática de modelos eficazes. O objetivo foi sinalizar para executivos e gerentes de empresas de médio porte aspectos relevantes para sua constituição e operacionalização, criando, assim, um panorama sobre a temática capaz de gerar novas alternativas para a tomada de decisão relativa ao assunto. Esse modelo é significativo porque conseguiu reduzir os aspectos voláteis e maximizar a voluntariedade dos empregados. O referido caso é rico em experiências, decisões e exemplos que podem ser adaptados e levados a outras empresas do mesmo porte. A análise criteriosa de todo o material de pesquisa levantado possibilitou a confirmação da afirmativa inicial, a qual priorizava a motivação como fator de criatividade e incremento de produção nas empresas de médio porte. Essas conclusões culminaram com a implantação do referido modelo, em maio de 1994, na Acesita Placas S/A - ACEPLAC.

Retenção de talentos por meio de reconhecimento e recompença

Esta dissertação objetivou verificar até que ponto os mecanismos de reconhecimento e recompensa são motivadores à retenção de talentos. Considerou que há pessoas que fazem o diferencial das organizações por deterem competências de difícil aquisição e de importância estratégica. No entanto, essas competências serão perdidas se não estiverem vinculadas aos objetivos das organizações e se não forem estabelecidas relações entre o desempenho e as práticas de reconhecimento e recompensa adotadas. Como base, buscou-se em disciplinas como a Psicologia, a Sociologia e as ciências da Administração, fundamentos teóricos que viessem auxiliar na resposta ao problema formulado. Este referencial mostrou a importância da retenção do talento, assim como descreveu e analisou algumas das muitas variáveis que poderiam impactar a construção de vínculos psicológicos entre o talento e a organização, ressaltando os principais componentes do processo motivacional na retenção. Também, permitiu identificar e analisar os principais mecanismos de reconhecimento e recompensa que poderiam ser adotados na valorização e retenção de talentos e relacionou-os com três correntes da motivação, criando um modelo conceitual de avaliação da retenção. Os resultados deste estudo serviram de orientadores à pesquisa de campo, que buscou conhecer quais os mecanismos de reconhecimento e recompensa que mais motivam os talentos a permanecerem em uma organização, bem como, avaliou se os mecanismos ditos motivadores, quando efetivamente praticados, causariam impacto na motivação do talento no decorrer do tempo. iii A análise dos resultados da pesquisa validou o modelo conceitual, concluindo que dos trinta e um mecanismos estudados apenas oito têm força de retenção, estando sete deles associados a formas de reconhecimento, aprovação e crescimento profissional. Os resultados não rejeitam as hipóteses e concluem que reconhecer e recompensar talentos vai muito além de abonos e prêmios pecuniários e materiais. Embora estímulos externos contribuam, a motivação em permanecer em uma organização é intrínseca ao talento e está associada ao seu espaço de vida, no momento em que ele se percebe integrado ao grupo, e respeitado, tendo seu esforço reconhecido e recompensado de forma justa.

Habitus, representações sociais e a construção do ser professora da educação infantil da cidade de Campina Grande - PB

We present here the results of a study whose objectives were to identify the social representation of being a professor of early childhood education in Campina Grande - PB, in the public state and municipal levels, and detect structural diagrams of a possible mental habitus of professorial faculty of education child, which would form the basis for the construction of this representation. As a theoretical base, we adopted the model developed by Domingos Sobrinho (1998, 2000, 2003, 2010, 2011), which articulates the Theory of Social Representations, Serge Moscovici, and the foundations and concepts of Pierre Bourdieu praxiology. It is based also on the Central Nucleus Theory, which focuses on the structural approach of social representations. Thus, puts in evidence the relational dynamics and symbolic, through which individuals come into contact, describe, understand and reproduce the outside world in his image and likeness. 199 teachers participated in the study of child care and pre-schools of Campina Grande - PB and 109 of the state. The methods and techniques used were: a) participant observation of everyday life of teachers of kindergartens and preschools, b) semi-structured interview, c) free associations of words with inducing the expression 'being a professor of early childhood education is ...' and d) semi-structured questionnaire. The data were analyzed in the case of interviews through the categorical content analysis, as proposed by Bauer (2010); free-associations, using the software Ensemble L'Analyse des Programmes Permettant evocations (EVOC), developed by Vergès (2002), which combines frequency and average order of recall (or association) and the questionnaire data, the Statistical Package for the Social Sciences (SPSS). It was verified the existence of a unique social representation shared by the population studied, but its content is structured differently. For local teachers, the centrality of the content is given by the elements commitment, dedication, responsibility, and rewarding teachers for this state revolves around the elements of love, patience, and rewarding responsibility. However, it is constructed mainly based on the related produced by a religious habitus and maternal habitus, which are part of the genesis of the establishment of professorial habitus in focus, among other cultural references of secondary influence. We conclude that a teacher of early childhood education actually researched, is materialized in the practices of educating and caring, in a clear fusion of the role of teacher and mother
