Constructing risk across timescales and trajectories: Gay men's stories of sexual encounters

This paper explores the way risk is constructed in the stories gay men tell of their sexual experiences. It focuses on how tellers use such stories to portray themselves both as rational actors and as legitimate members of their social groups by reconstructing the ‘orderliness’ of sexual encounters. An analysis of a corpus of stories derived from a diary study of gay male sexual behaviour in Hong Kong using current theories of discourse analysis reveals how narrators organize their experiences along two primary vectors of engagement: a sequential vector along which the trajectory of the sexual encounter is presented as a chain of occurrences, each occurrence contingent upon previous ones and warranting subsequent ones, and a hierarchical vector along which processes perceived on longer timescales are portrayed as exerting pressure on the ways processes on shorter timescales unfold. Examining how men portray these vectors in their accounts of risk behaviour can help us better understand both the situatedness of risk behaviour and the ways it is linked to larger social practices, identity projects and community histories

Transport of animals between rooms: A little-noted aspect of laboratory procedure that may interfere with memory

This study investigated the effects of transporting animals from the experimental room to the animal facility in between experimental sessions, a procedure routinely employed in experimental research, on long-term social recognition memory. By using the intruder-resident paradigm, independent groups of Wistar rats exposed to a 2-h encounter with an adult intruder were transported from the experimental room to the animal facility either 0.5 or 6h after the encounter. The following day, residents were exposed to a second encounter with either the same or a different (unfamiliar) intruder. Resident`s social and non-social behaviors were carefully scored and subjected to Principal Component Analysis, thus allowing to parcel out variance and relatedness among these behaviors. Resident rats transported 6h after the first encounter exhibited reduced amount of social investigation towards familiar intruders, but an increase of social investigation when exposed to a different intruder as compared to the first encounter. These effects revealed a consistent long-lasting (24h) social recognition memory in rats. In contrast, resident rats transported 0.5 h after the first encounter did not exhibit social recognition memory. These results indicate that this common, little-noted, laboratory procedure disturbs long-term social recognition memory. (C) 2011 Elsevier B.V. All rights reserved.

‘Moving on’ : Violence, wellbeing and questions about violence in antenatal care encounters. A qualitative study with Somali-born refugees in Sweden

Background Somali-born women constitute one of the largest groups of childbearing refugee women in Sweden after more than two decades of political violence in Somalia. In Sweden, these women encounter antenatal care that includes routine questions about violence being asked. The aim of the study was to explore how Somali-born women understand and relate to violence and wellbeing during their migration transition and their views on being approached with questions about violence in Swedish antenatal care. Method Qualitative interviews (22) with Somali-born women (17) living in Sweden were conducted and analysed using thematic analysis. Findings A balancing actbetween keeping private life private and the new welfare system was identified, where the midwife's questions about violence were met with hesitance. The midwife was, however, considered a resource for access to support services in the new society. A focus on pragmatic strategies to move on in life, rather than dwelling on potential experiences of violence and related traumas, was prominent. Social networks, spiritual faith and motherhood were crucial for regaining coherence in the aftermath of war. Dialogue and mutual adjustments were identified as strategies used to overcome power tensions in intimate relationships undergoing transition. Conclusions If confidentiality and links between violence and health are explained and clarified during the care encounter, screening for violence can be more beneficial in relation to Somali-born women. The focus on “moving on” and rationality indicates strength and access to alternative resources, but needs to be balanced against risks for hidden needs in care encounters. A care environment with continuity of care and trustful relationships enhances possibilities for the midwife to balance these dual perspectives and identify potential needs. Collaborations between Somali communities, maternity care and social service providers can contribute with support to families in transition and bridge gaps to formal social and care services.

Multiple visions or multiple aversions? Consumer representation, consultation and participation in maternity issues

This paper reviews the Commonwealth government's policy of 'purposeful reporting to consumers'. I argue that the notion of consumer participation is underdeveloped. Consumers' needs will not be fully met by confining consumer representation at the administrative level; that is, in assuming that consumer advocates may speak for other consumers of health care services. The partnership objective at the heart of 'purposeful reporting' may be addressed fully only when practitioners and providers recognise the reciprocal expertise of the consumer in defining their own health priorities. This would require a new model of knowledge, of ethics and of the clinical encounter. The problem is not one of information deficit but of contrasting views of knowledge.

Look down, look up : Barbara Bolt's art beyond representation

I review the thinking of Barbara Bolt in her recent book, which is informed by Martin Heidegger’s theory of art. Bolt argues that it is in the flux of art practice, where the artist responds bodily, with hands and eyes, to the encounter with the materials of practice, that visual art produces real material effects. That is, through the praxical encounter, art does not merely represent, it performs radically. Bolt thus argues for a materialist ontology of the work of visual art. I examine what Bolt means by ‘real material effects’ and ‘radical performativity’.

In developing my own project on the poetic response to visual art, particularly portraiture, I have freely adapted Heidegger’s theory of art to propose that the poet responds to the visual encounter in a manner similar to that of Heidegger’s preserver, by restraining usual knowing and looking. In this way the poet facilitates the emergence from the work of visual art of truth about being and earth, as defined by Heidegger. In my forthcoming article ‘Ekphrasis and illumination of painting’, I argue that the poet, like the artist, restrains seeing-as and operates in a mode approximating mere seeing, as these terms are defined by Heidegger and Wittgenstein.

In the present article I propose to examine the role of looking down and looking up in non-representational art, and in particular Bolt’s ‘oil stain paintings’ exhibited in the Forty-five Downstairs gallery in Melbourne in conjunction with the launch of her book.

I propose to expose some blind spots in the thinking which underpins theories derived from Heidegger. I will examine the way ‘representation’ has been constructed in twentieth-century thought, and will argue that Heideggerian truth and Bolt’s ‘real material effects’ result from the privileging of perception over knowledge. I will examine, with particular reference to portraiture, Bolt’s assertion that the referent can be rehabilitated in Western thought and traced in ‘real material effects’. I will argue that ‘representation’ is an unstable process occurring within and outside signification, and that this very instability enables us to confidently predict that all art produces ‘real material effects’, or in other words, Heideggerian truth.

Proposed multi-dimensional approach to evaluating service recovery

Purpose – The purpose of this paper is to extend thinking on service recovery processes and satisfaction with service recovery, using multi-dimensional consumer outcomes. The objective of the work was to propose that satisfaction with service recovery should be based on customers' expectations of the recovery encounter, which would be shaped by their expectations of “non-failed” encounters.

Design/methodology/approach – The paper adopts a theoretical approach. Using the existing service recovery literature as well as the traditional services literature, the conceptual framework and associated research propositions are developed.

Findings – The proposed framework suggests that service recovery is a service encounter it its own right. The effectiveness of recovery encounters will be based on how encounters operate relative to customer expectations and experiences with regard to the recovery activity.

Research limitations/implications – The research propositions and proposed framework need further empirical investigation.

Practical implications – The proposed framework suggests that managing service recovery should be undertaken in a similar fashion to managing any service, and thus managers need to understand customers' recovery expectations. Organisations also need to consider how a recovery action impacts on a range of customer outcomes, as focusing on one aspect will not capture consumers' full set of behaviours.

Originality/value – The proposed model identifies that service recovery should be evaluated with regard to consumers' recovery expectations and satisfaction is not based on expectations with regard to non-failed encounters.

Phenomenon of ordinariness in nursing

This phenomenological research aimed to illuminate the nature and effects of ordinariness in nursing and to discover whether the phenomenon enhanced the nursing encounter. The researcher worked as a participant observer with six registered nurses in a Professorial Nursing Unit. Following each interaction, the researcher wrote her impressions in a personal-professional journal and audiotaped conversations with the respective nurses and patients to gain their impressions. Using a theoretical framework of the phenomenological concepts of lived experience, Dasein, Being-in-the-world and fusion of horizons as an underpinning methodology, an initial hermeneutical analysis and interpretation of the impressions generated qualities and activities indicative of the aspects of the phenomenon of ordinariness in nursing. The second phase of the analysis and interpretation sought to illuminate the nature of the phenomenon itself. Eight actualities of the nature of the phenomenon emerged: 'allowingness,' 'straightforwardness,' 'self-likeness,' 'homeliness,' 'favourableness,' 'intuneness,' 'lightheartedness' and 'connectedness.' These actualities were described in relation to the phenomenon of interest. The effects of the phenomenon were the creative potential to enhance the nursing encounter and included many and various effects of facilitation, fair play, familiarity, family, favouring, feelings, fun and friendship. The research found that nurses and patients shared a common sense of humanity, which enhanced the nursing encounter. Within the context of caring, the nurses were ordinary people, perceived as being extraordinarily effective, by the very ways in which their humanness shone through their knowledge and skills, to make their whole being with patients something more than just professional helping. The shared sense of ordinariness between nurses and patients made them as one in then- humanness and created a special place, in which the relative strangeness of the experience of being in a health care setting, could be made familiar and manageable.

Coping with defeat : acute glucocorticoid and forebrain responses to social defeat vary with defeat episode behaviour

Individuals vary in the way in which they cope with stressful situations. It has been suggested that ‘active’ coping behaviour, characterised by aggression and territorial control, is more effective in moderating the stress associated with social defeat than ‘passive’ coping behaviour, as characterised by immobility, decreased reactivity, and low aggression. We used the rodent ‘resident/intruder’ paradigm to determine whether individual differences in coping behaviour modulate the acute adrenocortical response to social defeat. During the 10 min conflict episode, behaviours displayed by the intruder were recorded and subsequently scored. Intruders that engaged in large numbers of fights and/or frequently used physical structures to block the resident's approach (a behaviour referred to as ‘guarding’), displayed smaller corticosterone responses to defeat than other intruders. Corticosterone responses to defeat were unrelated to a measure of coping style preferences (defensive burying test) obtained prior to the defeat encounter. We further chose to investigate the neurobiological basis of this observation by comparing the patterns of defeat-induced neuronal activation in the forebrains of intruders that displayed high versus low numbers of defensive behaviours during the defeat episode. The results of this analysis indicated that ‘low fight’ and ‘low guard’ intruders, i.e. those that achieved a fight or a guard score below the 20th percentile, had significantly higher numbers of Fos-positive neurons in forebrain regions such as the medial prefrontal cortex and the amygdala than did control animals exposed to an empty resident's cage. In summary, the present data suggest that ‘active’ coping behaviour is associated with both a smaller adrenocortical response and a lower level of ‘neural activation’ following social defeat. This outcome differs from that of earlier studies, a difference that we suggest is due to the fact that the present study is the first to assess coping on the basis of behaviour actually displayed during the conflict interaction.

Reading, writing, crafting – Innovations in first year tertiary writing pedagogy

This paper will outline some of the rationale behind, and strategies contributing to, curriculum revision in first-year creative writing at Deakin University in 2012 – delivered in that year and currently running in 2013. The process aimed to produce two consecutive offerings, with distinct but strategically scaffolded preoccupations. This paper deals with the first of these. The design process for this offering, named ‘Writing Craft’, involved addressing two central concerns: (a) the need to unhook the initial encounter with tertiary creative writing pedagogy from a preoccupation with ‘genres’ or the ‘forms’ of creative writing (such as prose fiction, creative nonfiction, script, poetry, and so on) and instead to reorient efforts towards establishing an engagement with craft per se; (b) to address a perceived impoverishment in the range of texts to which students had been exposed prior to commencing study – in other words, to emphasise the practice of reading to facilitate the practice of writing. The curriculum design also involved reimagining assessment, noting the ‘messages about making’ sent to students via the framing of tasks and rubrics. Aiming instead to deemphasise the role of inspiration and ‘work arriving fully formed’, it sought to offer assessment that provided clear – and bounded – prompts for incidents of making and the practice of craft, as well as to provoke conversation with a broad range of texts as a way of courting intertextual inspiration and aesthetic formation.

Estimating cumulative exposure of wildlife to non-lethal disturbance using spatially explicit capture-recapture models

Impact assessments often focus on short-term behavioral responses of animals to human disturbance. However, the cumulative effects caused by repeated behavioral disruptions are of management concern because these effects have the potential to influence individuals' survival and reproduction. We need to estimate individual exposure rates to disturbance to determine cumulative effects. We present a new approach to estimate the spatial exposure of minke whales to whalewatching boats in Faxaflõi Bay, Iceland. We used recent advances in spatially explicit capture-recapture modeling to estimate the probability that whales would encounter a disturbance (i.e., whalewatching boat). We obtained spatially explicit individual encounter histories of individually identifiable animals using photo-identification. We divided the study area into 1-km2 grid cells and considered each cell a spatially distinct sampling unit. We used capture history of individuals to model and estimate spatial encounter probabilities of individual minke whales across the study area, accounting for heterogeneity in sampling effort. We inferred the exposure of individual minke whales to whalewatching vessels throughout the feeding season by estimating individual whale encounters with vessels using the whale encounter probabilities and spatially explicit whalewatching intensity in the same area, obtained from recorded whalewatching vessel tracks. We then estimated the cumulative time whales spent with whalewatching boats to assess the biological significance of whalewatching disturbances. The estimated exposure levels to boats varied considerably between individuals because of both temporal and spatial variations in the activity centers of whales and the whalewatching intensity in the area. However, although some whales were repeatedly exposed to whalewatching boats throughout the feeding season, the estimated cumulative time they spent with boats was very low. Although whalewatching boat interactions caused feeding disruptions for the whales, the estimated low cumulative exposure indicated that the whalewatching industry in its current state likely is not having any long-term negative effects on vital rates.

Snap

‘Snap’ deploys the queer cliché of becoming-sailor as a trope for recognition in the amorous encounter and literalises the ‘copycat’ as its catalyst. As Girard argues (1973), the human is foremost mimetic: this story makes its claim for originality and authenticity of connection through the playful recycling of cliché.‘Snap’ eschews the relative affectlessness of some metafiction by staging an amorous approach under the shadow of mortality. It exploits the liminal moment of modernist short fiction to summon the ‘manifold’ of experience. Here, love opens a space of intertextual esonance (Costello 2007), including motifs of Genet (masquerade), Duras (haunting) and Maurice Blanchot (the infinite approach), by writing the threshold of encounter as the intensive silence of wond

Defeitos pontuais nos compostos intermetálicos ZrNi e Zr/sub 2/Ni estudados por dinâmica molecular

Empregamos a técnica de Dinâmica Molecular para estudar propriedades de defeitos pontuais nos compostos intermetálicos ZrNi e Zr2Ni. Descrevemos as configurações estáveis de defeitos e mecanismos de migração, assim como as energias envolvidas. Os potenciais interatômicos foram derivados do Embedded Atom Model. No intuito de levar em conta a variação de estequiometria causada pela presença de alguns tipos de defeitos em intermetálicos, apresentamos um método numérico que fornece a energia efetiva de formação de defeitos e aplicamos o método ao ZrNi e Zr2Ni. Os resultados mostraram que vacâncias são mais estáveis na sub—rede do Ni, com energia de formação de 0,83 e-0,61 eV em ZrNi e Zr2Ni, respectivamente. Vacâncias de Zr são instáveis em ambos compostos; elas decaem espontaneamente em pares anti—sítio e vacância de Ni. Configurações e energias de formação de intersticiais também foram calculadas e mostraram comportamentos similares. Em ZrNi, a migração de vacâncias ocorre preferencialmente nas direções [025] e [100], com as respectivas energias de migração 0,67 e 0,73 eV, e é um processo essencialmente bidimensional no plano (001). Em Zr,Ni, a migração de vacâncias é unidimensional, ocorrendo na direção [001], com energia de migração de 0,67 eV. Em ambos compostos a presença de defeitos de anti—sítio de Ni diminui a energia de migração da vacância de Ni em até 3 vezes e facilita a movimentação em três dimensões. Mecanismos de anel não são energeticamente eficientes em comparação com saltos diretos. As configurações estáveis de intersticiais em ambos compostos consistem em um átomo de Ni sobre o plano (001) entre dois vizinhos de Zr fora do plano. Intersticiais de Zr são instáveis e tendem a deslocar um átomo de Ni, ocupando seu sítio. Energias de deslocamento foram estudadas através de simulações de irradiação de ambos compostos. Durante o processo de colisão binária, um potencial universal ZBL foi usado para colisões a curta distância. Para distâncias intermediárias usamos um potencial de união arbitrário. Zr mostrou—se mais difícil de ser arrancado de seu sítio do que Ni. Encontramos valores de energia de deslocamento no intervalo de aproximadamente 29 eV até 546 eV. Alguns resultados experimentais são mostrados e apresentam boa concordância com os cálculos.

A influência da qualidade do atendimento na decisão de compra

Neste estudo verifica-se a influência da qualidade do atendimento na decisão de compra de planos pós-pagos de telefonia móvel celular, bem como a existência de uma correlação entre o grau de conhecimento que o consumidor já possui sobre o serviço antes de adquiri-lo e a importância atribuída ao auxílio do vendedor no momento da compra. Para tanto, foi realizada uma pesquisa com pessoas que adquiriram planos pós-pagos nas lojas de uma operadora de telefonia móvel na cidade do Rio de Janeiro, por meio da qual foram analisados: o grau de conhecimento prévio dos compradores sobre os serviços, o grau de satisfação com o atendimento, a importância atribuída ao auxílio do vendedor para a tomada de decisão de compra, entre outros indicadores. A etapa quantitativa foi precedida de uma fase qualitativa, a fim de levantar os atributos considerados importantes pelos clientes para medir a qualidade de atendimento e, com base neles, construídos os questionários que, depois de aplicados e analisados, resultaram na constatação de uma correlação positiva entre a percepção de qualidade no atendimento e a decisão de compra. Os resultados são discutidos, bem como as implicações acadêmicas e gerenciais.

Dança, corpo e desenho: arte como sensação

Este trabalho busca refletir sobre o estatuto do corpo e do movimento nas artes a partir da noção de sensação, como empregada no pensamento do filósofo francês Gilles Deleuze. Tal propósito se fará a partir do singular encontro entre os trabalhos de um pintor/desenhista e um dos mais emblemáticos bailarinos clássicos. O corpo em movimento, quando atinge o estado de dança, não se reduz a uma forma, a uma representação, nem a uma mecânica. Antes, pelo contrário, sua leveza singular afeta-nos sobremaneira. Tal afecção será tomada como fio condutor de nossa análise, tendo em vista as diferentes sensações e expressões que pode suscitar. A sensação de um corpo que dança pode expressar-se na dança em si como também no desenho. Que relações esses diferentes meios de expressão do corpo dançarino podem estabelecer entre si? Que acontecimentos singulares podem emergir nesse encontro particular? Antes que forma, linhas de força e expressão. Corpo-vibração, torrente de afectos e perceptos, constituindo sensações que diferentes meios artísticos expressam diferentemente.

Papel das Yops secretadas por Yersinia sobre a resposta imune do hospedeiro

The genus Yersinia contains three species pathogenic to humans: Y. pestis, Y. enterocolitica e Y. pseudotuberculosis. The pathogenicity of Yersinia is linked to the presence of a 70-kb virulence plasmid (pYV) that is common to the three species and codifies a type III secretion system and a set of virulence proteins, including those known as Yersinia outer proteins (Yops), that are exported by this system when the bacteria encounter host cells. Two Yops translocators (YopB and YopD) are inserted into the host plasma membrane and transport six effectors (YopO, YopH, YopM, YopJ and YopT) across the membrane into the cytosol of the host cell. The Yops effectors interfere with multiple signaling pathways of the infected cell, affecting both the innate and adaptive immune responses. This article focuses on the role of Yops in the modulation of the host immune response.
