Theoretical explanations are that personal relationships offer direct behavioral and physiological pathways to longevity, as well as buffer stress and provide coping resources during critical life-events. These pathways often operate independently from age, sex, lifestyle, well-being, chronic diseases and functional limitations. Besides these insights, many studies fail to establish a strong link between social integration into personal networks and risk of mortality. We suggest that the life-prolonging effects may vary considerably across the different conceptualizations of integration into personal networks. Furthermore, research designs need to account for changes in the personal network during the aging process. The objective of this study is to model mortality risk depending on a variety of personal network characteristic...

This study examines how features of humanitarian work and aid workers' individual characteristics affect retention within one humanitarian organisation, Médecins Sans Frontières (MSF) Holland. The study extends existing research by providing new theoretical explanations of employment opportunities and constraints and by engaging in the first large-scale quantitative analysis of aid worker retention. Using a database of field staff (N=1,955), a logistic regression is performed of the likelihood of reenlistment after a first mission. The findings demonstrate that only 40 per cent of employees reenlist for a second mission with MSF Holland, and that workplace location and security situation, age, and gender have no significant effect. Individuals are less likely to reenlist if they returned early from the first mission for a personal reason, are in a relationship, are medical doctors, or if they c...

We apply self-determination theory to hypothesize about the role of physical needs and social resources on parental depression in a European context. A sample of 6,268 parents older than 65 who have nonresident children from the first wave of Survey of Health, Ageing and Retirement in Europe (2004) is analyzed. We estimate logistic regression models to test for the association between instrumental support and depression. Physical needs, gender, and social interaction are used as moderators. Net of core factors that contribute to depression, including previous history of depression, there is a U-shaped pattern between receiving instrumental support and depression that persists across country regimes. For respondents with medium physical limitations, too little or too frequent support from children is as...

The past half-century has witnessed a dramatic increase in such crises - such as in Haiti, Iraq and Sudan - and this volume aims to pioneer a theory-based, interdisciplinary framework that can assist students and practitioners in the field to acquire the skills and expertise necessary for evidence-based decision-making and programming in humanitarian action. It has four major objectives:
To provide a tool for diagnosing and understanding complex emergencies, and build on the concepts of state security and human security to provide a ‘Snap-Shot Analysis’ of the status quo;
To provide a tool for analysing the causes of crises as well as the related stakeholder field;
To provide a frame to structure and analyse the information required to evaluate, monitor and/or design interventions for different actors on a project and/or programme level;
To combine concepts used in the humanitarian field with underlying theory in a practically relevant way.
The book will be of much interest to students of humanitarian intervention, human security, peacebuilding, development studies, peace studies and IR in general.
