    ‘My life's properly beginning’: young people with a terminally ill parent talk about the future

    This paper explores how young people who are living with a parent who is dying talk about the future. Drawing on a qualitative, interview study, I argue that young people are able to move imaginatively beyond the death of a parent, and in doing so, to maintain a sense of biographical continuity. While thinking about the future, most were able to generate an alternative to the ‘harm story’ typically associated with parental loss. Furthermore, the facility to engage with parental absence in the present enabled young people to make sense of living with dying, and gave meaning to their imagined futures. These findings suggest that young people's narratives of the future may act as a symbolic resource to draw on, albeit one requiring adequate material and social resources to construct. The paper extends the notion of continuing bonds derived from post‐bereavement accounts to suggest that relational experiences of the dead begin prior to bereavement, and may facilitate everyday living in anticipation of significant loss. Enabling young people to imaginatively explore the future may support them in getting by when they are living in these difficult family circumstances

    Bereavement and the role of religious and cultural factors.

    yesThe aim of this article is to give an overview of some of the key dimensions of variation in cultural and religious rituals during the immediate period after a death and in the longer term, in order to inform service delivery in multi-cultural societies. For each area we give examples of different customs, and consider their functions and possible impact. Dimensions considered in the immediate period after bereavement are: The time and space given to formal rituals, expression of feelings, assertion of status and disposal of the body. In the longer term, we look at variations in remembering the deceased and in continuing bonds. Throughout we consider the interplay between individual responses and the personÂżs cultural and religious context. Our objective is to provide an accessible introduction for practitioners new to working with bereavement and provide a succinct reference point for more experienced bereavement workers.Full text made available 1st May 2014 at the end of the publisher's embargo period

    The Case for a Sociology of Dying, Death and Bereavement

    Get PDF
    YesDying, death and bereavement do not occur in a social vacuum. How individuals and groups experience these phenomena will be largely influenced by the social context in which they occur. To develop an adequate understanding of dying, death and bereavement we therefore need to incorporate a sociological perspective into our analysis. This paper examines why a sociological perspective is necessary and explores various ways in which sociology can be of practical value in both intellectual and professional contexts. A case study comparing psychological and sociological perspectives is offered by way of illustration

    Runaway Events Dominate the Heavy Tail of Citation Distributions

    Statistical distributions with heavy tails are ubiquitous in natural and social phenomena. Since the entries in heavy tail have disproportional significance, the knowledge of its exact shape is very important. Citations of scientific papers form one of the best-known heavy tail distributions. Even in this case there is a considerable debate whether citation distribution follows the log-normal or power-law fit. The goal of our study is to solve this debate by measuring citation distribution for a very large and homogeneous data. We measured citation distribution for 418,438 Physics papers published in 1980-1989 and cited by 2008. While the log-normal fit deviates too strong from the data, the discrete power-law function with the exponent Îł=3.15\gamma=3.15 does better and fits 99.955% of the data. However, the extreme tail of the distribution deviates upward even from the power-law fit and exhibits a dramatic "runaway" behavior. The onset of the runaway regime is revealed macroscopically as the paper garners 1000-1500 citations, however the microscopic measurements of autocorrelation in citation rates are able to predict this behavior in advance.Comment: 6 pages, 5 Figure

    Hormonal Signal Amplification Mediates Environmental Conditions during Development and Controls an Irreversible Commitment to Adulthood

    Get PDF
    Many animals can choose between different developmental fates to maximize fitness. Despite the complexity of environmental cues and life history, different developmental fates are executed in a robust fashion. The nematode Caenorhabditis elegans serves as a powerful model to examine this phenomenon because it can adopt one of two developmental fates (adulthood or diapause) depending on environmental conditions. The steroid hormone dafachronic acid (DA) directs development to adulthood by regulating the transcriptional activity of the nuclear hormone receptor DAF-12. The known role of DA suggests that it may be the molecular mediator of environmental condition effects on the developmental fate decision, although the mechanism is yet unknown. We used a combination of physiological and molecular biology techniques to demonstrate that commitment to reproductive adult development occurs when DA levels, produced in the neuroendocrine XXX cells, exceed a threshold. Furthermore, imaging and cell ablation experiments demonstrate that the XXX cells act as a source of DA, which, upon commitment to adult development, is amplified and propagated in the epidermis in a DAF-12 dependent manner. This positive feedback loop increases DA levels and drives adult programs in the gonad and epidermis, thus conferring the irreversibility of the decision. We show that the positive feedback loop canalizes development by ensuring that sufficient amounts of DA are dispersed throughout the body and serves as a robust fate-locking mechanism to enforce an organism-wide binary decision, despite noisy and complex environmental cues. These mechanisms are not only relevant to C. elegans but may be extended to other hormonal-based decision-making mechanisms in insects and mammals

    A Response to the IPCC Fifth Assessment

    Get PDF
    This collection of essays is the initial product of the second meeting of the Environmental Law Collaborative, a group of environmental law scholars that meet to discuss important and timely environmental issues. Here, the group provides an array of perspectives arising from the Fifth Assessment of the Intergovernmental Panel on Climate Change. Each scholar chose one passage from one of the IPCC’s three Summaries for Policymakers as a jumping-off point for exploring climate change issues and responding directly to the reports. The result is a variety of viewpoints on the future of how law relates to climate change, a result that is the product not only of each scholar’s individual knowledge but also of the group’s robust discussion

    A Small Conductance Calcium-Activated K<sup>+</sup> Channel in C. elegans, KCNL-2, Plays a Role in the Regulation of the Rate of Egg-Laying

    In the nervous system of mice, small conductance calcium-activated potassium (SK) channels function to regulate neuronal excitability through the generation of a component of the medium afterhyperpolarization that follows action potentials. In humans, irregular action potential firing frequency underlies diseases such as ataxia, epilepsy, schizophrenia and Parkinson's disease. Due to the complexity of studying protein function in the mammalian nervous system, we sought to characterize an SK channel homologue, KCNL-2, in C. elegans, a genetically tractable system in which the lineage of individual neurons was mapped from their early developmental stages. Sequence analysis of the KCNL-2 protein reveals that the six transmembrane domains, the potassium-selective pore and the calmodulin binding domain are highly conserved with the mammalian homologues. We used widefield and confocal fluorescent imaging to show that a fusion construct of KCNL-2 with GFP in transgenic lines is expressed in the nervous system of C. elegans. We also show that a KCNL-2 null strain, kcnl-2(tm1885), demonstrates a mild egg-laying defective phenotype, a phenotype that is rescued in a KCNL-2-dependent manner. Conversely, we show that transgenic lines that overexpress KCNL-2 demonstrate a hyperactive egg-laying phenotype. In this study, we show that the vulva of transgenic hermaphrodites is highly innervated by neuronal processes and by the VC4 and VC5 neurons that express GFP-tagged KCNL-2. We propose that KCNL-2 functions in the nervous system of C. elegans to regulate the rate of egg-laying. © 2013 Chotoo et al
