Prevalence of Adverse Childhood Experiences in a University Population: Associations with Use of Social Services

This paper is part of a series published by the Multiple Adverse Childhood Experiences research group based at QUB. First-year undergraduates took part in an online survey, self-reporting on Adverse Childhood Experiences (ACE) and measures of social service contact. The 10-item ACE questionnaire measures abuse, neglect and household dysfunction (current sample ?????????The study achieved a response rate of 18.6%. (N=765; 552 (72.7%) females and 212 (27.2%) males; 21.8% reporting having been educated at a ‘Protestant’ school, 42% reporting having been educated at a ‘Catholic’ school and 20.4% reporting previous school religious affiliation as ‘other’). Despite obvious non-response bias, ACE scores for this student population are comparable with college-educated populations in the US. Current respondents with previous social service contact are over twenty three times more likely than peers to have experienced multiple adversities. Findings support the hypothesis that social service contact, alone, acts as a proxy indicator for the presence of multiple adverse childhood experiences, with no significant elevation in ACE scores for those going through court proceedings or subject to child protection registration. This study supports current concerns by policy makers to target those children experiencing multiple adversities.

Older people's views of support services in response to elder abuse in communities across Ireland

Purpose – This paper seeks to present findings from the first all-Ireland study that consulted older people on their perceptions of interventions and services to support people experiencing abuse.

Design/methodology/approach – Utilising a grounded theory approach, 58 people aged 65 years and over took part in focus groups across Ireland. Four peer-researchers were also trained to assist in recruitment, data collection, analysis, and dissemination.

Findings – Participants identified preventative community-based approaches and peer supports as important mechanisms to support people experiencing, and being at risk of, elder abuse. Choices regarding care provision and housing, as well as opportunities for engagement in community activities where they can discuss issues with others, were identified as ways to prevent abuse.

Originality/value – The development of elder abuse services has traditionally been defined from the perspective of policy makers and professionals. This study looked at the perspective of the end-users of such services for the first time. The research also gave an active role to older people in the research process. The policy implication of the findings from this research is that enhanced attention and resources should be directed to community activities that enable older people to share their concerns informally thereby gaining confidence to seek more formal interventions when necessary.

Strategies for Effective Management of Health and Safety in Confined Site Construction

The overall aim of this research is to identify and catalogue the numerous managerial strategies for effective management of health and safety on a confined, urban, construction site. A mixed methods methodology was adopted using interviews and focus group discussions on three selected case studies of confined construction sites. In addition to these, a questionnaire survey was used based on the findings from the interviews and the focus group discussions. The top five key strategies include (1) Employ safe system of work plans to mitigate personnel health and safety issues; (2) Inform personnel, before starting on-site, of the potential issues using site inductions; (3) Effective communication among site personnel; (4) Draft and implement an effective design site layout prior to starting on-site; and (5) Use of banksman (traffic co-ordinator) to segregate personnel from vehicular traffic. The construction sector is one of the leading industries in accident causation and with the continued development and regeneration of our urban centres, confined site construction is quickly becoming the norm - an environment which only fuels accident creation within the construction sector. This research aids on-site management that requires direction and assistance in the identification and implementation of key strategies for the management of health and safety, particularly in confined construction site environments.

Wellness as virtue:Morality and the pursuit of health

The interest and participation in health promotion and wellness activities has expanded greatly in the past two decades. The "wellness revolution", especially in terms of diet and exercise, has been affected by both scientific findings and cultural changes. The paper examines how a particular aspect of culture, the moral meanings of health-promoting activities, contribute to the pursuit of wellness. Based on interviews with 54 self-identified wellness participants at a major university, we examine how health can be a moral discourse and the body a site for moral action. The paper suggests that wellness seekers engage in a profoundly moral discourse around health promotion, constructing a moral world of goods, bads and shoulds. Although there are some gender differences in particular wellness goals, engaging in wellness activities, independent of results, becomes seen as a good in itself. Thus, even apart from any health outcomes, the pursuit of virtue and a moral lifeis fundamentally an aspect of the pursuit of wellness. © 1994 Kluwer Academic Publishers.

Design technique for mm-wave IC realization of the load network of switched-mode class-EF power amplifier

Analysis and synthesis of the new Class-EF power amplifier (PA) are presented in this paper. The proposed circuit offers means to alleviate some of the major issues faced by existing Class-EF and Class-EF PAs, such as (1) substantial power losses due to parasitic resistance of the large inductor in the Class-EF load network, (2) unpredictable behaviour of practical lumped inductors and capacitors at harmonic frequencies, and (3) deviation from ideal Class-EF operation mode due to detrimental effects of device output inductance at high frequencies. The transmission-line load network of the Class-EF PA topology elaborated in this paper simultaneously satisfies the Class-EF optimum impedance requirements at fundamental frequency, second, and third harmonics as well as simultaneously providing matching to the circuit optimum load resistance for any prescribed system load resistance. Furthermore, an elegant solution using an open and short-circuit stub arrangement is suggested to overcome the problem encountered in the mm-wave IC realizations of the Class-EF PA load network due to lossy quarter-wave line. © 2010 IEICE Institute of Electronics Informati.

Regulatory network of lipopolysaccharide O-antigen biosynthesis in Yersinia enterocolitica includes cell envelope-dependent signals

Lipopolysaccharide (LPS) is a glycolipid present in the outer membrane of all Gram-negative bacteria, and it is one of the signature molecules recognized by the receptors of the innate immune system. In addition to its lipid A portion (the endotoxin), its O-chain polysaccharide (the O-antigen) plays a critical role in the bacterium-host interplay and, in a number of bacterial pathogens, it is a virulence factor. We present evidence that, in Yersinia enterocolitica serotype O:8, a complex signalling network regulates O-antigen expression in response to temperature. Northern blotting and reporter fusion analyses indicated that temperature regulates the O-antigen expression at the transcriptional level. Promoter cloning showed that the O-antigen gene cluster contains two transcriptional units under the control of promoters P(wb1) and P(wb2). The activity of both promoters is under temperature regulation and is repressed in bacteria grown at 37 degrees C. We demonstrate that the RosA/RosB efflux pump/potassium antiporter system and Wzz, the O-antigen chain length determinant, are indirectly involved in the regulation mainly affecting the activity of promoter P(wb2). The rosAB transcription, under the control of P(ros), is activated at 37 degrees C, and P(wb2) is repressed through the signals generated by the RosAB system activation, i.e. decreased [K+] and increased [H+]. The wzz transcription is under the control of P(wb2), and we show that, at 37 degrees C, overexpression of Wzz downregulates slightly the P(wb1) and P(wb2) activities and more strongly the P(ros) activity, with the net result that more O-antigen is produced. Finally, we demonstrate that overexpression of Wzz causes membrane stress that activates the CpxAR two-component signal transduction system.

Correlates of health status for family caregivers in bereavement

The purpose of this retrospective cohort study was to identify aspects of caregiving associated with health status among family caregivers in bereavement. Study participants included 151 family caregivers of terminally ill patients who had died, on average, 294 days prior to the study telephone interview. The interview covered two main areas: patient characteristics and caregiver characteristics. Multivariate linear regressions revealed that as the age of the care recipient (regression coefficient [b] = -0.32; 95% confidence interval [CI] -0.48,-0.15) and caregiver (b = -0.14; 95% CI = -0.25, -0.02) increased, caregivers experienced a decline in their physical health during bereavement. Furthermore, caregivers who reported that caregiving interrupted their usual activities (b = -5.97; 95% CI = -9.79, -2.15) had a decline in physical health during bereavement. A poorer mental health status during bereavement was seen in caregivers who reported poor physical health during caregiving (b = -4.31; 95% CI = -8.17, -0.45); and that they received insufficient family support in caregiving (b = -6.01; 95% CI = -9.75, -2.27). It was also revealed that a home death was associated with higher mental health of the caregiver (b = 3.55; 95% CI = 0.26, 6.84). The practice implications of these findings are discussed in this paper.

The influence of health education on family management of childhood asthma

The purpose of this study was to examine differences in asthma management among families with a child who has moderate to severe asthma. Half of the 50 families chosen for study had participated in an intensive in-patient asthma treatment program and half had participated in an out-patient day camp. Two broad categories of outcome were examined - illness and self-management skills. Families who participated in the in-patient program exhibited a pattern of illness behaviours which indicated asthma symptoms were better managed in comparison to those families that participated in the out-patient program. It was also observed that children who participated in the in-patient program had a tendency to feel more positive about having asthma with the more self-management behaviours they practised. On the other hand, children from the out-patient program reported a more negative attitude about having asthma with the more self-management behaviours they practised.
