Cold-induced silencing by long antisense transcripts of an Arabidopsis Polycomb target.

Transcription in eukaryotic genomes generates an extensive array of non-protein-coding RNA, the functional significance of which is mostly unknown. We are investigating the link between non-coding RNA and chromatin regulation through analysis of FLC - a regulator of flowering time in Arabidopsis and a target of several chromatin pathways. Here we use an unbiased strategy to characterize non-coding transcripts of FLC and show that sense/antisense transcript levels correlate in a range of mutants and treatments, but change independently in cold-treated plants. Prolonged cold epigenetically silences FLC in a Polycomb-mediated process called vernalization. Our data indicate that upregulation of long non-coding antisense transcripts covering the entire FLC locus may be part of the cold-sensing mechanism. Induction of these antisense transcripts occurs earlier than, and is independent of, other vernalization markers and coincides with a reduction in sense transcription. We show that addition of the FLC antisense promoter sequences to a reporter gene is sufficient to confer cold-induced silencing of the reporter. Our data indicate that cold-induced FLC antisense transcripts have an early role in the epigenetic silencing of FLC, acting to silence FLC transcription transiently. Recruitment of the Polycomb machinery then confers the epigenetic memory. Antisense transcription events originating from 3' ends of genes might be a general mechanism to regulate the corresponding sense transcription in a condition/stage-dependent manner.

The Interview:An Ethnographic Approach

What are new interview methods and practices in our new 'interview society' and how do they relate to traditional social science research? This volume interrogates the interview as understood, used - and under-used - by anthropologists. It puts the interview itself in the hotseat by exploring the nature of the interview, interview techniques, and illustrative cases of interview use.

What is a successful and representative interview? How are interviews best transcribed and integrated into our writing? Is interview knowledge production safe, ethical and representative? And how are interviews used by anthropologists in their ethnographic practice?

This important volume leads the reader from an initial scrutiny of the interview to interview techniques and illustrative case studies. It is experimental, innovative, and covers in detail matters such as awkwardness, silence and censorship in interviews that do not feature in general interview textbooks. It will appeal to social scientists engaged in qualitative research methods in general, and anthropology and sociology students using interviews in their research and writing in particular.

Berryman, Sexton and the Possibilities of Poetic Language

This paper examines a select number of poems by Middle Generation poets John Berryman and Anne Sexton in relation to questions of death, silence and the task that literature sets itself as understood in key works by Blanchot, Heidegger, and Levinas. Rather than recourse to the overtrodden critical path of confessional interpretations of their work, this paper connects Berryman’s The Dream Songs (1969) and two Sexton poems (‘Oh’ and ‘The Silence’) to the philosophical determinations of what it is language can say and what demands literature makes of the writer prepared to risk their own being in answer to its call. Central issues such as suicide and the originating silence of the work of art are intricately interwoven with Berryman’s and Sexton’s work. Leaving aside their biographies, and by approaching suicide as a philosophical problem with which their poetry wrestles, a restructured approach to their work becomes available. The impulse to suicide and the mental processes involved in considering and committing the act are instincts and responses located within an individual’s own psychology. For these writers particularly such issues are sited within a philosophical debate about language, what it can and cannot represent. If poetry articulates language’s argument about its own capability, it is the ideal forum for philosophical confrontations with the possibilities of existence as represented by the grave decision to take one’s own life. © The Author 2013.

Heeding the stains: Lacan and organizational change

Purpose: The purpose of this paper is to add to current discussions on the use of Lacanian psychoanalysis in organizational change. Specifically, It argues that critiques of Lacan's work must be acknowledged and incorporated into these discussions. To date, there remains a silence surrounding these critiques within organization studies.
Design/methodology/approach: The paper presents the existing studies that draw upon Lacan's work in the context of organizational change initiatives. It highlights the value of this theory. Next, it outlines critiques of Lacan's concepts of phallus and incest taboo, and show how these concepts can be exclusionary.
Findings: The paper finds that there remains little debate within organization studies around such critiques. Lacan tends to be employed in ways that risk reproducing particular, exclusionary aspects of his theory. A homophobic and patriarchal legacy persists in appropriations of his writing. It outlines alternative ways of reading Lacan, which aim to avoid such exclusions. It shows how introducing such alternatives is a difficult project, first, given the silence surrounding critiques of Lacan in the organizational change literature. Second, following Foucault, It argues that language has power: a patriarchal schema is self-reinforcing in its persistence within a particular discipline, and thus difficult to dislodge.
Research limitations/implications: Given these findings, the paper concludes that organization theorists and practitioners ought to engage with critiques of Lacan's work, when employing it in their own. The silence surrounding such legacies is dangerous. It argues that the first step in engaging with Lacan's work should be to give voice to such critiques, if his writing is to be employed in the practice and study of organizational change.
Originality/value: This paper provides a unique engagement with Lacan's work in the context of the study and practice of organizational change interventions. It presents an evaluation of well-known critiques and useful recommendations for theorists and practitioners considering a Lacanian approach to this area of management studies. © Emerald Group Publishing Limited.

Explaining Prolonged Silences in Transitional Justice: The Disappeared in Cyprus and Spain

The article examines why some postconflict societies defer the recovery of those who forcibly disappeared as a result of political violence, even after a fully fledged democratic regime is consolidated. The prolonged silences in Cyprus and Spain contradict the experience of other countries such as Bosnia, Guatemala, and South Africa, where truth recovery for disappeared or missing persons was a central element of the transition to peace and democracy. Exhumations of mass graves containing the victims from the two periods of violence in Cyprus (1963–1974) and the Spanish Civil War (1936–1939) was delayed up until the early 2000s. Cyprus and Spain are well suited to explain both prolonged silences in transitional justice and the puzzling decision to become belated truth seekers. The article shows that in negotiated transitions, a subtle elite agreement links the non-instrumental use of the past with the imminent needs for political stability and nascent democratization. As time passes, selective silence becomes an entrenched feature of the political discourse and democratic institutions, acquiring a hegemonic status and prolonging the silencing of violence.

Finding Your Feet in the Field: Critical Reflections of Early Career Researchers on Field Research in Transitional Societies

Fieldwork that takes place in conflict or transitional regions is becoming increasingly popular amongst early-career and more seasoned researchers, but is an area that retains an air of mystery and remains an exotic form of knowledge gathering. There exists a paucity of personal reflection on the challenges associated with conducting fieldwork in conflicted or transitional regions and a limited amount of insight into the practical steps taken in advance of and when immersed in the field. Such reticence to share honest fieldwork experiences, particularly the more challenging research that takes place in conflict or transitional settings aids in creating a culture of silence. This paper attempts to counteract this silence by drawing on the challenges experienced by two early career researchers conducting fieldwork in Uganda and Palestine, focusing on the practical steps taken in advance of entering the field, and the challenges faced whilst engaged in fieldwork. Specific challenges are highlighted throughout, including: physical access to areas in conflict; engaging with reluctant research participants; the emotional impact of fieldwork on the researcher; maintaining confidentiality; researching with vulnerable victims; and ensuring appropriate knowledge exchange between researchers and participants. The paper concludes by emphasising the requirement for greater reflection on the inherently personal challenges associated with conducting fieldwork in conflicted or transitional settings and highlights the view that fieldwork is a privileged position that carries great responsibilities which must be upheld to ensure the sustainability of future research. This paper hopes to contribute to the wider debate on conducting fieldwork and the challenges associated with working in conflicted or transitional regions.

Truth Recovery and Transitional Justice: Deferring human rights issues

This book investigates why some societies defer the solution of transitional justice issues, such as the disappeared/missing, even after successful democratic consolidation. It also explains why the same societies finally decide to deal with these human rights issues. In short, it considers the interesting and understudied phenomenon of post-transitional justice. The prolonged silences in Spain, Cyprus and Greece contradict the experience of other countries -- such as South Africa, Bosnia, and Guatemala -- where truth recovery for disappeared/missing persons was a central element of the transition to peace and democracy. Despite democratization, the exhumation of mass graves containing the victims from the violence in Cyprus (1963-1974) and the Spanish civil war (1936-1939) was delayed until the early 2000s, when both countries suddenly decided to revisit the past. Cyprus and Spain are not alone: this is an increasing trend among countries trying to come to terms with past violence. Interestingly, despite similar background conditions, Greece is resisting the trend, challenging both theory and regional experience. Truth Recovery and Transitional Justice considers three interrelated issues. First, what factors can explain prolonged silence on the issue of missing persons in some transitional settings? Second, which processes can address the occasional yet puzzling transformation of victims’ groups from opponents of truth recovery to vocal pro-reconciliation pressure groups? Third, under which conditions is it better to tie victims’ rights to an overall political settlement? The book looks at Spain and Cyprus to show how they have attempted to bring closure to deep trauma by exhuming and identifying their missing, albeit under considerably different conditions. It then probes the generalizability of the conclusions on Spain and Cyprus by looking at the Greek experience; oddly, despite similar background conditions, Greece remains resistant to post-transitional justice norms. Interestingly, each case study takes a different approach to transitional justice.

Delaying Truth Recovery for Missing Persons

The fate of missing persons is a central issue in post-conflict societies facing truth recovery and human rights dilemmas. Despite widespread public sympathy towards relatives, societies emerging from conflict often defer the recovery of missing for decades. More paradoxically, in post-1974 Cyprus, the official authorities delayed unilateral exhumations of victims buried within cemeteries in their own jurisdiction. Analysis of official post-1974 discourse reveals a Greek-Cypriot consensus to emphasise the issue as one of Turkish aggression, thus downplaying in-group responsibilities and the legacy of intra-communal violence. We compare the experience of Cyprus with other post-conflict societies such as Spain, Northern Ireland, and Mozambique and explore the linkages between institutions and beliefs about transitional justice. We argue that elite consensus initiates and facilitates the transition to democracy but often leads to the institutionalization of groups opposing truth recovery even for in-group members.

Older women living and coping with domestic violence

Although domestic violence is seen as a serious public health issue for women worldwide, international evidence suggests that women aged over 50 who are victims are suffering in silence because the problem is often ignored by health professionals. More UK research is needed to identify the extent of the problem, and services to meet the needs of older women. This study aims to bridge this gap by gaining a deeper understanding of how ‘older women’ cope with domestic violence and how it affects their wellbeing. Eighteen older women who were currently, or had been in an abusive relationship were recruited. Semi-structured interview schedules were used to discuss the personal nature of DV and its effects on wellbeing, ways of coping and sources of support. Findings suggest that living in a domestically violent context has extremely negative effects on older women’s wellbeing leading to severe anxiety and depression. Three-quarters of the women defined themselves as in ‘very poor’ mental and physical health and were using pathogenic coping mechanisms, such as excessive and long-term use of alcohol, prescription and non-prescription drugs and cigarettes. This negative coping increased the likelihood of these women experiencing addiction to drugs and alcohol dependence and endangered their health in the longer term. Our findings suggest that health professionals must receive appropriate education to gain knowledge and skills in order to deal effectively and support older women experiencing domestic violence.

Older Women Living with Domestic Violence: Coping Resources and Mental Health and Wellbeing

Background: Domestic violence represents a serious public health issue for women and their children worldwide. International evidence suggests that women aged over 50 who are victims of domestic violence are suffering in silence because the problem is ignored by professionals and policy makers. More UK research is needed to identify the extent of the problem, and services to meet the needs of older women.

Study aims: To bridge this gap by seeking to gain a deeper, systematic understanding of how ‘older women’ cope with domestic violence and how it effects their wellbeing, using a theoretical framework of ‘salutogenesis’ to consider coping resources used in lifelong abuse.

Methods: The study recruited a convenience sample of eighteen older women who are currently, or had been in an abusive relationship. A semi-structured interview schedule was used to discuss the personal nature, of domestic violence in their lives, and the pattern of abuse over time and its effects on their wellbeing, ways of coping and sources of support, barriers to reporting and accessing support, and experiences in seeking help.

Results: Living in a domestically violent context has extremely negative effects on older women’s wellbeing. Living with a perpetrator of long-term violence is predisposing these women to extremely negative health outcomes such as Post Traumatic Stress Disorder, anxiety and depression. Three-quarters of the women defined themselves as in poor mental health and were using pathogenic coping mechanisms, such as excessive and long-term use of alcohol, prescription and non-prescription drugs and cigarettes. This negative coping increased the likelihood of these women experiencing addiction to drugs and alcohol dependence and endangering their health and wellbeing in the longer term. Conclusions Public health interventions can work well from a ‘salutogenic’ perspective by finding ways to promote healthy behaviours that increase older women’s sense of wellbeing and coping. The application of this theoretical framework offers the potential for new knowledge to contribute to the discourse about wellbeing in older women dealing with domestic violence.

Tumorigenesis and peritoneal colonization from fallopian tube epithelium

Ovarian cancer is the most lethal gynecological malignancy, primarily because its origin and initiation factors are unknown. A secretory murine oviductal epithelial (MOE) model was generated to address the hypothesis that the fallopian tube is an origin for high-grade serous cancer. MOE cells were stably altered to express mutation in p53, silence PTEN, activate AKT, and amplify KRAS alone and in combination, to define if this cell type gives rise to tumors and what genetic alterations are required to drive malignancy. Cell lines were characterized in vitro and allografted into mice. Silencing PTEN formed high-grade carcinoma with wide spread tumor explants including metastasis into the ovary. Addition of p53 mutation to PTEN silencing did not enhance this phenotype, whereas addition of KRAS mutation reduced survival. Interestingly, PTEN silencing and KRAS mutation originating from ovarian surface epithelium generated endometrioid carcinoma, suggesting that different cellular origins with identical genetic manipulations can give rise to distinct cancer histotypes. Defining the roles of specific signaling modifications in tumorigenesis from the fallopian tube/oviduct is essential for early detection and development of targeted therapeutics. Further, syngeneic MOE allografts provide an ideal model for pre-clinical testing in an in vivo environment with an intact immune system.

Speaking Out Online:The Benefits and Risks of Speaking About Sexual Violence for Young People

Speaking out about sexual violence has been a fundamental part of feminist politics since the 1970s. The practice of narrating experiences of violence, either publicly or to friends and family aims to combat the culture of silence and stigmatisation that surrounds sexual violence while also helping individuals to gain a sense of empowerment and connect with other survivors. However, speaking out also contains inherent risks, especially for young people. Survivors may meet with stigmatising or disbelieving responses, and they may lose control over who knows their story and the way in which it is told and retold.
These risks and benefits are altered, and potentially exacerbated, in an online environment. While social media may increase survivors’ ability to contact and connect with others with similar experiences it also makes it harder to control when and how their story is shared. The disjuncture between online and offline environments may also increase feelings of stigmatisation and isolation.
There is a need to explore the specific risks and benefits of speaking out online given both young people’s extensive use of social media for social interactions and the increasing tendency for support and educational services targeted at young people to make use of social media and online environments. This paper draws on literature and some preliminary research to consider both risks and benefits of speaking out online and to open a conversation about the creation of supportive spaces and mechanisms for young people to speak about sexual violence in online environments.

A morte e o luto em contexto escolar: das vivências na primeira pessoa à (re) significação do conceito de escola acolhedora

A morte é, porventura, o grande tabu da sociedade ocidental contemporânea, fenómeno com clara ressonância na forma como os sobreviventes vivenciam o luto por perda de figura significativa. Numa sociedade que se mantém à margem da morte, as emoções decorrentes do luto são escamoteadas e reprimidas, com sérios riscos para a saúde mental dos enlutados. Essa conspiração do silêncio desagua também nos contextos educativos, onde os valores da juventude, do bem-estar, do prazer e da felicidade, quase não deixam espaço para o sofrimento e a morte. Deste modo, este estudo pretende ser uma contribuição para a compreensão dos efeitos do processo de luto em alunos adolescentes, nomeadamente ao nível do seu desempenho escolar, e, concomitantemente, para a análise do tipo de apoio que a comunidade educativa proporciona a esses alunos, com enfoque no papel dos professores (em geral) e dos diretores de turma (em particular). Pretende ainda apresentar estratégias interventivas, a implementar nas escolas, potenciadoras de uma educação para a vida, mesmo em circunstâncias de morte, e para a gestão do luto, que se revelem promotoras de um lidar pedagógico inclusivo. Sendo o luto um processo que afeta o indivíduo em todas as dimensões que o definem, um paradigma educacional que encontre na complexidade a sua matriz identitária, foi assumido neste estudo como o único capaz de resgatar a importância da gestão equilibrada dos afetos no processo de ensinoaprendizagem. À luz deste paradigma que assume um princípio de totalidade, partindo da totalidade, ou seja, que promove o desenvolvimento do ser humano na sua multidimensionalidade, assumimos também que a missão suprema e última da educação é a construção do sujeito ético. E é nos marcos de uma educação integral, humanista e ética, de responsabilidade pelo Outro, que ganha contornos a figura do professor cuidador, como sendo alguém atento às necessidades emocionais dos seus alunos. Do ponto de vista metodológico, esta investigação desenvolveu-se de acordo com uma abordagem de natureza predominantemente qualitativa, interpretativa e complexa e o estudo realizado centrou-se em três fases, tendo a recolha de dados decorrido entre setembro de 2009 e setembro de 2012: (i) Estudo exploratório, dirigido aos Diretores das 61 escolas secundárias do Distrito do Porto, com base num questionário adaptado, com o objetivo de sustentar a importância e pertinência do estudo principal e recolher indicadores para o orientar; (ii) Estudo de Caso Coletivo, envolvendo três alunas adolescentes em luto por perda de pai. Na primeira parte, e com vista à caracterização do contexto, a escola frequentada pelas três alunas, procedeuse à análise documental, concretamente do Projeto Educativo, mas também ao inquérito por entrevista a vários agentes da comunidade educativa: o Diretor, a Psicóloga, a Coordenadora dos Diretores de Turma do ensino secundário e seis Diretores de Turma. Na segunda parte, procedeu-se a uma abordagem holística e aprofundada da complexidade inerente a cada caso, procurando dar “voz” à forma única como cada uma das alunas vivenciou, significou e enfrentou a sua experiência de luto, tendo-se recorrido ao inquérito por entrevista. De forma a cruzar perspetivas de vários informantes, e identificar significados transversais, complementares ou alternativos, foram também entrevistadas as Encarregadas de Educação e os Diretores de Turma das alunas; (iii) Caraterização das conceções de professores sobre a temática em análise e validação de propostas de intervenção a implementar nas escolas, mobilizando-se, assim, dimensões emergentes das Fases I e II da investigação, mas também do quadro teórico que sustentou o estudo. Para a recolha de dados, foi construído um questionário que se aplicou aos professores do 2º e 3º ciclos do ensino básico e ensino secundário do Agrupamento onde se centrou o estudo de caso desenvolvido na Fase II. Procurando uma leitura global dos resultados obtidos e corroborando o que é amplamente defendido na literatura da especialidade, o estudo demonstra o impacto negativo que o luto tem no desempenho escolar e revela que o padrão afetivo da ambiência escolar não é favorável à expressão emocional de alunos enlutados, prevalecendo uma atitude de evitação por parte dos colegas e professores, o que sugere a necessidade de serem trilhados novos caminhos, por um lado, ao nível da formação de professores e, por outro lado, através da implementação em contexto escolar de uma intervenção pedagógica que eduque para a vida, mas sem descurar os fenómenos de perda afetiva significativa e respetivas vivências de luto. Deste estudo sai também reforçada a responsabilidade acrescida dos Diretores de Turma na constituição de um ethos de suporte envolvendo alunos em luto, cabendo-lhes um importante papel na articulação entre os vários agentes da comunidade educativa. Em suma: para além da necessidade de repensar o perfil de competências dos professores, mais consentâneo com o paradigma de escola acolhedora, deste estudo ressalta também a premência de validar na prática propostas de intervenção articuladas, consistentes e, sobretudo, éticas.

A performance do silêncio na música contemporânea para oboé

O presente estudo tem como objectivo entender todo o universo anexo à performance do silêncio na música clássica contemporânea. Numa nova perspectiva: o estudo do impacto da ansiedade num músico que se observa e que observa a sua interação com o contexto artístico que o rodeia, são estudadas todas as variáveis com influência directa no acto de percepção e gestão dos momentos de ausência de som. Tendo por base os princípios da investigação qualitativa foi criado um modelo teórico de análise na área dos estudos em performance. Este modelo foi aplicado em dois recitais realizados na Universidade de Aveiro e num concerto do Remix Ensemble da Casa da Música do Porto. O uso de ferramentas de pesquisa: O teste do Cortisol e o uso do colete Vitaljacket®, permitiu observar comportamentos fisiológicos no performer e no público nunca antes relatados. Os principais resultados desta investigação permitem aferir a elevada complexidade do fenómeno perceptivo e performativo do silêncio na música contemporânea. A pesquisa realizada permitiu observar que o silêncio na música contemporânea acontece num contexto de elevada ambiguidade semântica e que a duração dada a este num concerto, está directamente dependente do quadro fisiológico observado no performer no momento do concerto. Foi ainda possível aferir que a repetição, numa data posterior, de um mesmo programa de concerto provoca uma acentuada descida dos níveis de ansiedade no performer e essa descida altera a forma como este gere, em concerto, os momentos de silêncio. As conclusões alcançadas em sede de investigação reforçam a pertinência deste estudo. São postas à prova concepções altamente empíricas sobre a performance dos silêncios em música contemporânea. As asserções formuladas têm impacto a nível pedagógico e didático. São apontadas direcções de investigação futura no sentido da valorização do estudo da gestão dos momentos de silêncio em performance.
