Extending Bayesian back-calculation to estimate age and time specific HIV incidence

Lifetime Data Analysis - CD4-based multi-state back-calculation methods are key for monitoring the HIV epidemic, providing estimates of HIV incidence and diagnosis rates by disentangling their...     

‘Who do I turn to if something really bad happens?’ Key working and relationship-based practice in residential child care

ABSTRACT

This article explores the psychodynamics of relationship-based practice from the perspective of young people in residential care. This research involved qualitative semi-structured interviews with 10 care leavers, aged 18–24 years, who had been in residential care in Ireland. Drawing selectively from that research, this article reports their views and experiences of key-working and how relationship-based practice acted as a reparative method within their experiences of care and aftercare. Similar to previous research, this study underscores the necessity to ensure that children in care are cared for and supported by a trusted adult. In addition, based on this study, the role of a key worker appears capable of providing this ideal type of supportive relationship. It also highlights the importance of the care system working to provide consistency and support for the young people and confirms the importance of relationships with trusted adults, such as key workers.     

Swedish-finnish return migration,extent, timing,and information flows

This paper performs two tasks. It first describes the return migration behavior of Finnish immigrants to Sweden over the period 1968–1976 as revealed by the Swedish population register. The volume of return migration is considerable but varies by age and sex. Second, we examine the sensitivity of return migration to economic conditions at both destination and origin. The model proposed allows the relative weights attached to information on the two locations to vary as the interval of absence lengthens. Econometric evidence indicates that conditions at the original location appear to exert increasing influence on the decision to return the longer the interval of absence.     

Safety sans Frontières: An International Safety Culture Model

The management of safety culture in international and culturally diverse organizations is a concern for many high‐risk industries. Yet, research has primarily developed models of safety culture within Western countries, and there is a need to extend investigations of safety culture to global environments. We examined (i) whether safety culture can be reliably measured within a single industry operating across different cultural environments, and (ii) if there is an association between safety culture and national culture. The psychometric properties of a safety culture model developed for the air traffic management (ATM) industry were examined in 17 European countries from four culturally distinct regions of Europe (North, East, South, West). Participants were ATM operational staff (n = 5,176) and management staff (n = 1,230). Through employing multigroup confirmatory factor analysis, good psychometric properties of the model were established. This demonstrates, for the first time, that when safety culture models are tailored to a specific industry, they can operate consistently across national boundaries and occupational groups. Additionally, safety culture scores at both regional and national levels were associated with country‐level data on Hofstede's five national culture dimensions (collectivism, power distance, uncertainty avoidance, masculinity, and long‐term orientation). MANOVAs indicated safety culture to be most positive in Northern Europe, less so in Western and Eastern Europe, and least positive in Southern Europe. This indicates that national cultural traits may influence the development of organizational safety culture, with significant implications for safety culture theory and practice.     

The impact of labor migration on the Jordanian economy

"This article considers the effects of labor migration on the economy of the East Bank of the Hashemite Kingdom of Jordan. The article is presented in two sections. The first attempts to quantify the external migrant flows which impinge on the Jordanian labor market. The second section presents a theoretical model of the macroeconomic impact on output and employment of flows of migrants and migrants' remittances and an empirical analysis of the effects on the agricultural and construction sectors."     

Mental health social work in Northern Ireland and the Republic of Ireland: challenges and opportunities for developing practice

Drawing on their experience of mental health social work in Northern Ireland and the Republic of Ireland, the authors examine the impact of current legislative and policy change in both jurisdictions. The paper applies Lorenz's theoretical framework to develop a comparative analysis of how global and country specific variables have interacted in shaping mental health social work. The analysis identifies linkages between factors and indicates similarities and differences in mental health social work practice. The paper highlights emerging discourses in this field and explores the impact on practice of developments such as de-institutionalisation, community care, and ‘user rights’ versus ‘public protection’. The article concludes with a review of key challenges facing social workers in both jurisdictions and identifies opportunities for developing mental health social work in ways that can positively respond to change and effectively address the needs of mental health service users and their carers. The analysis provides an opportunity to evaluate Lorenz's theoretical framework and the paper includes a brief critical commentary on its utility as a conceptual tool in comparative social work.     

Factor interaction influences on human performance in air traffic control: the need for a multifactorial model

In air traffic management (ATM) knowledge of the impact of human factors on performance is critical to address safety incidents. Previous research has largely focused on the effects of single factors on performance which has resulted in a comprehensive understanding of single factor effects. In current control environments however, the residual threats for incidents often result from the interaction of multiple human factors and the resulting cumulative impact on performance. This research uses a literature review, an analysis of over 400 European aviation incident reports and finally a survey of ATM professionals to assess the need for a multifactorial model of performance. Literature findings suggest that Human Factors approaches are fundamentally single-factor in nature, which is out of step with real ATM working contexts. An incident report analysis, supported by a survey of air traffic experts, suggests that multiple factor incident causation exists. This discrepancy suggests the need for a new approach to looking at how incidents occur, and their factors managed, on a day-to-day basis. The proposed solution is a multifactorial model of human performance.
