'Sometimes I wish I was an "ex" ex-prisoner': identity processes in the collective action participation of former prisoners in Northern Ireland

Since the signing of the Northern Ireland peace agreement a plethora of community based prisoner self-help organisations have been established wherein former prisoners staff, manage and deliver services to colleagues. By forging and maintaining their collective identities through community based mutual aid, members of these self-help organisations have progressed to create not only individual change/assistance but have also developed and evolved to tackle serious wider social issues which impact on the members of their organisations. This article critically analyses how the conditions of a post conflict society can influence both the development and evolution of these organisations and also how members situate their claims about the self in the organisation and beyond. Using the social movement framework it is argued that the work of these self-help organisations have given rise to a new politics of identity … that is the ‘politically motivated’ ex-prisoner. ©2013 Taylor & Francis

The Senses of Muriel Rukeyser’s The Book of the Dead

When Muriel Rukeyser travelled to Gauley Bridge in 1936 to report on the industrial disaster that had led to the deaths of over 700 miners, her findings led her to write what is arguably her masterpiece – the 1938 poem series The Book of the Dead. Of all Rukeyser's writings, this hybrid work of documentary techniques and metaphors, of testimony and elegy, has attracted the most critical attention. However, analyses of the series have tended to focus on the ways in which the poet adopted and adapted documentary methods in order to offer a leftist ideological critique on capitalist-born social injustice. The purpose of this article is not to negate such readings, but to offer alongside them insight into a more ethical-philosophical approach that I believe guided Rukeyser's entire career. Via an examination of the ways in which Rukeyser employs the human senses to articulate the complexities of human political, metaphysical and social relations, this article explores the influence of the Zionist Martin Buber on the poet. Rukeyser acknowledged Buber's writings in her later work, but I contend here that they played a large part in the formation of her poetics, especially in connection with her documentary aesthetic. Whilst several critics have noted, albeit often superficially, the Marxist flavour of Rukeyser's poetry in The Book of the Dead, I argue for the influence of Buber over Marx in terms or responsibility, community and dialogue. Both Rukeyser's and Buber's methods of expressing and promoting these ethical necessities rely on a synaesthetic response to the world. Where Buber advances a dialogue between the self and alterity through transcendent personal encounter, Rukeyser locates such encounter in the poem, arguing for an exchange that leads to creation, and to personal and interpersonal growth.

Occupational stress in the chef profession

Purpose – The purpose of this paper is to consider the occupational stress experienced by chefs and the moderating influence of coping behaviour and locus of control on stress outcomes. Design/methodology/approach – A total of 40 working chefs were surveyed. They were asked to complete an occupational stress questionnaire, the General Health Questionnaire. Differences were
sought between gender and locus of control and stress measures, and correlations were carried out between key variables. Findings – The reported stress was markedly higher than in previous research. Excessive workload,
feeling undervalued and communication issues were common and bullying and threats of violence were present for some. Unexpectedly, locus of control was unable to predict stress experiences. Explanations were offered, such as the possibility that those who perceive they have a strong sense of control may believe that this, paradoxically, affords them the opportunity to engage in unhealthy behaviours. Research limitations/implications – Limitations of the research include the influence of the wider environment, specifically the history of political violence in the province, and its possible effect on stress outcomes. However, this may be negated by the many positive effects peace has brought over the last decade. In drawing conclusions it is important to note the limitations of the sample size and the self-reporting nature of survey responses. Further research could usefully incorporate well-being as well as stress measures, including physiological ones. It would be worth exploring further how one’s sense of control affects perceptions of stress and, in turn, the coping behaviours engaged in. Practical implications – Practical implications include the need for managers and head chefs to provide more feedback to employees, to validate their good work and to foster a supportive working environment. Norms in the working environment endorsing aggressive behaviour must be challenged.
Staff appraisals should consider the need to have work that involves variety and challenge, especially where changes involve increases in workload. Originality/value – This paper identifies some important ingredients to reduce distress and it will be of value to chefs and other kitchen staff and, more broadly, to those involved in people management.

The spirit of palliative practice:A qualitative inquiry into the spiritual journey of palliative care physicians

Objective: Much is known about the important role of spirituality in the delivery of multidimensional care for patients at the end of life. Establishing a strong physician-patient relationship in a palliative context requires physicians to have the self-awareness essential to establishing shared meaning and relationships with their patients. However, little is known about this phenomenon and therefore, this study seeks a greater understanding of physician spirituality and how caring for the terminally ill influences this inner aspect. Method: A qualitative descriptive study was used involving face-to-face interviews with six practicing palliative care physicians. Results: Conceptualized as a separate entity from religion, spirituality was described by participants as a notion relating to meaning, personal discovery, self-reflection, support, connectedness, and guidance. Spirituality and the delivery of care for the terminally ill appeared to be interrelated in a dynamic relationship where a physician's spiritual growth occurred as a result of patient interaction and that spiritual growth, in turn, was essential for providing compassionate care for the palliative patient. Spirituality also served as an influential force for physicians to engage in self-care practices. Significance of results: With spirituality as a pervasive force not only in the lives of palliative care patients, but also in those of healthcare providers, it may prove to be beneficial to use this information to guide future practice in training and education for palliative physicians in both the spiritual care of patients and in practitioner self care.

Knowledge and perceived competence among nurses caring for the dying in long-term care homes

Background: The quality of care provided to dying long-term care (LTC) residents is often inadequate, which may be due to the lack of formal training that LTC staff receive in palliative care (PC). This cross-sectional study assessed PC knowledge and self-efficacy in ability to provide PC in a sample of registered nurses working in LTC homes. Method: A survey was conducted in four LTC homes in October 2009 to June 2010. Nursing staff knowledge of PC was evaluated using the Palliative Care Quiz for Nurses (PCQN). The Self-Efficacy in End-of-Life Care Survey (S-EOLC) was used to measure nursing staff confidence in their ability to provide PC. Findings: Close to 60% of the nursing staff participated (69 of 119). The participants did not score highly on the PCQN: the average correct score ranged from 52.50% to 63.41% across the homes. There were no significant differences between the homes for the mean number of correct responses on the PCQN (P=0.329) or mean scores for the three S-EOLC subscales. Rank ordering of the percentage of correct PCQN answers by item and LTC home demonstrated that similar misconceptions were held across homes. Conclusion: Despite their confidence in PC practice, the participants' PC knowledge gap reveals a need for PC training for staff working in LTC homes. The PC education and training provided should both include a gerontological perspective and address the expertise and knowledge already held by staff.

Self-reported use of natural health products:A cross-sectional telephone survey in older Ontarians

Background: The self-reported use of natural health products (NHPs) (herbal products and vitamin and mineral supplements) has increased over the past decade in Canada. Because the elderly population might have comorbidities and concurrently administered medications, there is a need to explore the perceptions and behaviors associated with NHPs in this age group. Objective: The goal of this study was to assess the use of NHPs in a cohort of older Canadian residents and the characteristics, perceptions, and behaviors associated with NHP use. Methods: Survey participants aged =60 years were randomly selected from telephone listings in the area of greater Hamilton, Ontario, Canada. Data were collected using a standardized computer-assisted telephone interview system. Self-reported data covering 7 domains were collected: (1) demographics; (2) self-reported 12-month NHP use; (3) reasons for NHP use; (4) self-reported 12-month prescription medication use; (5) expenditures on NHPs; (6) patient-reported adverse events and drug-NHP interactions; and (7) perceptions of physicians' attitudes regarding NHPs. Descriptive statistics were used to compare the characteristics of NHP users with those of nonusers and to assess the characteristics of NHP users across these 7 domains. Multivariate regression analysis was conducted to determine the demographic variables that might be associated with NHP user status. Results: Of 2528 persons identified as age =60 years, 1206 (48%) completed the telephone interview. Six hundred sixteen of these respondents (51%) reported the use of =1 NHP during the previous 12 months. On the initial univariate analysis, younger age and higher income were significantly associated with reporting NHP use (mean age, users vs nonusers, 71.1 vs 72.7 years, respectively; 95% CI, 1.02-1.06; P <0.001; income more than Can $26,000 was 28% and 22% in users and nonusers, respectively; P = 0.028). One hundred seventy of 616 users (28%) used an NHP to treat the same condition for which they were concurrently receiving a prescription medication, and 43 (25%) had not informed their physicians about their NHP use. Patients' characteristics such as sex, education, smoking status, and self-reported health status did not differ significantly between users and nonusers. In individuals who regularly spent money to purchase NHPs (n = 394), the mean cost was $20.38/mo. NHP expenditure was not significantly associated with age, sex, or income. Conclusion: Based on these findings, a substantial proportion of those Ontarians aged =60 years reported NHP use, and there is a need for greater communication with physicians to avoid potential drug-NHP interactions. © 2009 Excerpta Medica Inc.

Combating the mental health stigma with nostalgia

We report research implicating nostalgia as an intrapersonal means of warding off the stigmatization of persons with mental illness. We hypothesized and found that nostalgia about an encounter with a person with mental illness improves attitudes toward the mentally ill. In Experiment 1, undergraduates who recalled an encounter with a mentally ill person while focusing on central (vs. peripheral) features of the nostalgia prototype reported a more positive outgroup attitude. This beneficial effect of nostalgia was mediated by greater inclusion of the outgroup in the self (IOGS). In Experiment 2, undergraduates who recalled a nostalgic (vs. ordinary) interaction with a mentally ill person subsequently showed a more positive outgroup attitude. Results supported a serial mediation model whereby nostalgia increased social connectedness, which predicted greater IOGS and outgroup trust. IOGS and outgroup trust, in turn, predicted more positive outgroup attitudes. We ruled out alternative explanations for the results (i.e., mood, perceived positivity, and typicality of the recalled outgroup member). The findings speak to the intricate psychological processes underlying the prejudice-reduction function of nostalgia and their interventional potential. Copyright © 2013 John Wiley & Sons, Ltd.

Enquiring about traumatic experiences in bipolar disorder: A case note and self- report comparison

Objectives: This study examined: (i) the prevalence of lifetime trauma, childhood trauma and trauma related to civil unrest in a Bipolar Disorder sample, and (ii) the agreement between rates of disclosure of trauma in case notes and self-report questionnaires.

Methods: The case notes of sixty participants, recruited from a geographically well-defined mental health service in Northern Ireland, were examined for reports of experiences of lifetime, childhood and traumatic events related to civil conflict. The participants also completed self-report measures of trauma.

Results: Considerable differences were found between the prevalence of trauma as measured by self-report questionnaires and case notes reports. The prevalence of lifetime trauma as measured by the Trauma History Questionnaire was 61.7% (compared to case notes prevalence of 33.3%). The prevalence of moderate and severe levels of childhood trauma as measured by the Childhood Trauma Questionnaire was 65% (case notes 21.7%). Rates of trauma related to civil unrest were 35% (case notes 3.3%). Poor levels of agreement were found between all self-report trauma measures and case notes reports. Agreement on two categories of trauma (childhood emotional neglect and childhood physical neglect) reached statistical significance but kappa scores suggest this agreement was poor (kappa = .14. p<.05; kappa = .127, p<.05). © 2011 Elsevier B.V. All rights reserved.

Conclusions: It is probable that the increased rate of trauma disclosed in the self-report questionnaire arises because clinicians during initial assessment and subsequent treatment do not consistently enquire about trauma. The need for staff training is discussed. (C) 2011 Elsevier B.V. All rights reserved.

Beyond ourselves: Passion and the dark side of identification in an ethical organization

How are organizational discourses enacted by people at work? In this article, instead of treating subjects as somewhat distinct from such discourses, I argue that the two are inescapably intertwined. The concept of 'ek-stasis' helps us to understand this. Ekstasis invokes an idea of the 'self ' that, through processes of identification, is always located outside of itself, embedded in a wider sociality. I explore this dynamic through an in-depth study of the powerful discourse of 'ethical living', and its enactment in one contemporary development sector organization, EWH. This ek-static enactment was somewhat ambivalent: involving mutual recognition between colleagues, but also processes of exclusion and policing. I highlight how attention to feeling and passion was important in understanding the relation between workplace discourse and identification processes, in this setting. This study shows that a view of workplace selves as ek-static is useful for understanding the enactment of discourse at work, and that this enactment can be both passionate and ambivalent. © The Author(s) 2010.

Targeting treatment resistant breast cancer stem cells with FKBPL and its peptide derivative, AD-01, via the CD44 pathway

PURPOSE: FKBPL and its peptide derivative, AD-01, have already demonstrated tumour growth inhibition and CD44 dependent anti-angiogenic activity. Here we explore the ability of AD-01 to target CD44 positive breast cancer stem cells (BCSCs). EXPERIMENTAL DESIGN: Mammosphere assays and flow cytometry were utilized to analyse the effect of FKBPL overexpression/knockdown and AD-01 treatment ± other anti-cancer agents on BCSCs using breast cancer cell lines (MCF-7/MDA-231/ZR-75), primary patient samples and xenografts. Delays in tumour initiation were evaluated in vivo. The anti-stem cell mechanisms were determined using clonogenic assays, qPCR and immunofluorescence. RESULTS: AD-01 treatment was highly effective at inhibiting the BCSC population by reducing mammosphere forming efficiency (MFE) and ESA+/CD44+/CD24- or ALDH+ cell subpopulations in vitro and tumour initiation in vivo. The ability of AD-01 to inhibit the self-renewal capacity of BCSCs was confirmed; mammospheres were completely eradicated by the third generation. The mechanism appears to be due to AD-01-mediated BCSC differentiation demonstrated by a significant decrease in the number of holoclones and an associated increase in meroclones/paraclones; the stem cell markers, Nanog, Oct4 and Sox2, were also significantly reduced. Furthermore, we demonstrated additive inhibitory effects when AD-01 was combined with the Notch inhibitor, DAPT. AD-01 was also able to abrogate a chemo- and radiotherapy induced enrichment in BCSCs. Finally, FKBPL knockdown led to an increase in Nanog/Oct4/Sox2 and an increase in BCSCs, highlighting a role for endogenous FKBPL in stem cell signalling. CONCLUSIONS: AD-01 has dual anti-angiogenic and anti-BCSC activity which will be advantageous as this agent enters clinical trial.

Universal behaviour of shock precursors in the presence of efficient cosmic ray acceleration

The self-consistent interaction between energetic particles and self-generated hydromagnetic waves in a cosmic ray pressure dominated plasma is considered. Using a three-dimensional hybrid magnetohydrodynamics (MHD)-kinetic code, which utilizes a spherical harmonic expansion of the Vlasov-Fokker-Planck equation, high-resolution simulations of the magnetic field growth including feedback on the cosmic rays are carried out. It is found that for shocks with high cosmic ray acceleration efficiency, the magnetic fields become highly disorganized, resulting in near isotropic diffusion, independent of the initial orientation of the ambient magnetic field. The possibility of sub-Bohm diffusion is demonstrated for parallel shocks, while the diffusion coefficient approaches the Bohm limit from below for oblique shocks. This universal behaviour suggests that Bohm diffusion in the root-mean-squared field inferred from observation may provide a realistic estimate for the maximum energy acceleration time-scale in young supernova remnants. Although disordered, the magnetic field is not self-similar suggesting a non-uniform energy-dependent behaviour of the energetic particle transport in the precursor. Possible indirect radiative signatures of cosmic ray driven magnetic field amplification are discussed.

Xheal: A localized self-healing algorithm using expanders

We consider the problem of self-healing in reconfigurable networks e.g., peer-to-peer and wireless mesh networks. For such networks under repeated attack by an omniscient adversary, we propose a fully distributed algorithm, Xheal, that maintains good expansion and spectral properties of the network, while keeping the network connected. Moreover, Xheal does this while allowing only low stretch and degree increase per node. The algorithm heals global properties like expansion and stretch while only doing local changes and using only local information. We also provide bounds on the second smallest eigenvalue of the Laplacian which captures key properties such as mixing time, conductance, congestion in routing etc. Xheal has low amortized latency and bandwidth requirements. Our work improves over the self-healing algorithms Forgiving tree [PODC 2008] andForgiving graph [PODC 2009] in that we are able to give guarantees on degree and stretch, while at the same time preserving the expansion and spectral properties of the network.

Self-healing systems and virtual structures

Modern networks are large, highly complex and dynamic. Add to that the mobility of the agents comprising many of these networks. It is difficult or even impossible for such systems to be managed centrally in an efficient manner. It is imperative for such systems to attain a degree of self-management. Self-healing i.e. the capability of a system in a good state to recover to another good state in face of an attack, is desirable for such systems. In this paper, we discuss the self-healing model for dynamic reconfigurable systems. In this model, an omniscient adversary inserts or deletes nodes from a network and the algorithm responds by adding a limited number of edges in order to maintain invariants of the network. We look at some of the results in this model and argue for their applicability and further extensions of the results and the model. We also look at some of the techniques we have used in our earlier work, in particular, we look at the idea of maintaining virtual graphs mapped over the existing network and assert that this may be a useful technique to use in many problem domains.

Comparative study on transport properties for LiFAP and LiPF6 in alkyl-carbonates as electrolytes through conductivity, viscosity and NMR self-diffusion measurements

We present in this work a comparative study on density and transport properties, such as the conductivity (sigma), viscosity (eta) and self-diffusion coefficients (D), for electrolytes based on the lithium hexafluorophosphate, LiPF6; or on the lithium tris(pentafluoroethane)-trifluorophosphate, LiFAP dissolved in a binary mixture of ethylene carbonate (EC) and dimethylcarbonate (DMC) (50:50 wt%). For each electrolyte, the temperature dependence on transport properties over a temperature range from 10 to 80 degrees C and 20 to 70 degrees C for viscosity and conductivity, respectively, exhibits a non-Arrhenius behavior. However, this dependence is correctly correlated by using the Vogel-Tamman-Fulcher (VTF) type fitting equation. In each case, the best-fit parameters, such as the pseudo activation energy and ideal glass transition temperature were then extracted. The self-diffusion coefficients (D) of the Li+ cation and PF6- or FAP(-) anions species, in each studied electrolyte, were then independently determined by observing Li-3, F-19 and P-31 nuclei with the pulsed-gradient spin-echo (PGSE) NMR technique over the same temperature range from 20 to 80 degrees C. Results show that even if the diffusion of the lithium cation is quite similar in both electrolytes, the anions diffusion differs notably. In the case of the LiPF6-based electrolyte, for example at T approximate to 75 degrees C (high temperature), the self-diffusion coefficients of Li+ cations in solution (D (Li+)approximate to 5 x 10(-19) m(2) s(-1)) is 1.6 times smaller than that of PF6- anions (D (PF6-) = 8.5 x 10(-19) m(2) s(-1)), whereas in the case of the LiFAP-based electrolyte, FAP(-) anions diffuse at same rate as the Li+ cations (D (FAP(-)) = 5 x 10(-1) m(2) s(-1)). Based on these experimental results, the transport mobility of ions were then investigated through Stokes-Einstein and Nernst-Einstein equations to determine the transport number of lithium t(Li)(+), effective radius of solvated Li+ and of PF6- and FAP(-) anions, and the degree of dissociation of these lithium salts in the selected EC/DMC (50:50 wt%) mixture over a the temperature range from 20 to 80 degrees C. This study demonstrates the conflicting nature of the requirements and the advantage of the well-balanced properties as ionic mobility and dissociation constant of the selected electrolytes.

Assessing the needs of informal caregivers to cancer survivors: a review of the instruments

Objective: Cancer may impact negatively on an informal caregiver's health long after treatment has ended. This review identifies the self-report measures currently in use to measure caregivers need for support and determines their scientific soundness and clinical utility.

Method: A systematic electronic database search of Medline, CINAHL, PsychINFO, BNI ProQuest was conducted. The psychometric properties and clinical utility of needs assessment tools for caregivers of cancer survivors (excluding advanced disease) were extracted and summarised.

Results: Seven cancer survivor caregiver needs assessment tools were identified. Data on instrument development was well reported, although variability was noted in their structure and content. The majority demonstrated some degree of reliability and validity; only two were evaluated for test–retest reliability (CaSPUN and SPUNS) with only the SPUNS showing a high degree of reliability over time. The Health Care Needs Survey (HCNS), Needs Assessment of Family Caregivers-Cancer (NAFC-C) and Cancer Caregiving Tasks Consequences and Needs Questionnaire (CaTCoN) have been validated at various stages of the cancer continuum. Minimal data was available on responsiveness.

Conclusion: All assessment tools identified require further psychometric analysis. For research purposes, the use of the SPUNS (with its acceptable test–retest reliability) appears most appropriate; although its length may be of concern for clinical use; therefore, the shorter SCNS-P&C is likely to be more suitable for use clinically. At present, the NAFC-C demonstrates a great potential in both the research and clinical environments; however, it requires further psychometric testing before it can be fully recommended. Further analysis is necessary on ideal response formats and the meaning of a total needs score.
