A future agenda for research on climate change and human mobility

In the past 15 years, research activities focusing on the interlinkages between climate change and human mobility have intensified. At the same time, an increasing number of actors and processes have sought to address human mobility in the context of climate change from a policy perspective. Hitherto, research has been limited in terms of geographical preferences as well as conceptual and methodological focus areas. This paper argues that to address the evolving policy space, future research on climate change in the context of human mobility needs to become more differentiated, integrated and generalized. This includes concerted efforts to better integrate researchers from the global South, improved cross-linkages between different datasets, approaches and disciplines, more longitudinal and comparative studies and development of innovative qualitative and quantitative methods.     

Negotiating Risk and Promoting Empowerment through Rap Music: Development of a Measure to Capture Risk and Empowerment Pathways to Change

The purpose of this study was to report on the development and construction of the Individual and Community Empowerment (ICE) inventory, a measure seeking to capture the specific pathways by which either risk-enhancing impacts or empowering impacts of rap music manifest. Data were analyzed via structural equation modeling from a convenience sample of 128 high school and college students. Results found that respondents elicited (1) empowering themes that related to them individually and to the broader community and (2) high-risk themes that may promote risky health behaviors. Implications about research and practice relevance of the ICE inventory are discussed.     

Hardness and algorithms for rainbow connection

An edge-colored graph G is rainbow connected if any two vertices are connected by a path whose edges have distinct colors. The rainbow connection of a connected graph G, denoted rc(G), is the smallest number of colors that are needed in order to make G rainbow connected. In the first result of this paper we prove that computing rc(G) is NP-Hard solving an open problem from Caro et al. (Electron. J. Comb. 15, 2008, Paper R57). In fact, we prove that it is already NP-Complete to decide if rc(G)=2, and also that it is NP-Complete to decide whether a given edge-colored (with an unbounded number of colors) graph is rainbow connected. On the positive side, we prove that for every ε>0, a connected graph with minimum degree at least ε n has bounded rainbow connection, where the bound depends only on ε, and a corresponding coloring can be constructed in polynomial time. Additional non-trivial upper bounds, as well as open problems and conjectures are also presented.     

Disaster and response:science, systems and realities

The Indian Ocean Tsunami of December 2004 was one of the most significant natural disasters in modern history. The response that it drew was unprecedented at both local and international levels. While a range of specific impacts and losses may be predicted within the affected populations, there is substantial evidence that adverse impacts upon mental health may represent one of the most significant outcomes of such events. People from poorer countries are disproportionately exposed to such emergencies and may experience greater psychosocial burden in the aftermath, as well as a range of adaptations. This raises important questions regarding the current capacity of response agencies to mitigate negative impacts but also concerning the cultural context in which such mental health effects are defined. It also calls into question whether "indicated" interventions are both realistic and ecologically valid in non-Western settings. The science of Disaster Mental Health is a relatively new field, currently engaged in a number of such debates. However, there is some emerging consensus about what constitutes good public mental health practice throughout the phases of emergency response and across diverse cultural settings. Existing data and practice guidelines provide frameworks that may be adapted to allow health and recovery workers to identify and reduce mental health morbidity, support healing and harness the agency of those affected for the recovery process.     

Informal workers and Kenya’s National Hospital Insurance Fund: Identifying barriers to voluntary participation

This article investigates the barriers to informal workers’ voluntary participation in Kenya’s national health insurance scheme – the National Hospital Insurance Fund. Based on primary data from both qualitative and quantitative methods, we find that the key determinants of enrolment include social factors, such as marital status, which create demand for insurance, and the role of informal workers’ associations that promote the voluntary uptake of health insurance and prevent default through contribution support. Participation barriers and reasons for inactiveness stem from the nature of informal work characterized by irregular earnings, which combine with apprehension about having to pay penalty charges for the late payment of premiums, inadequate levels of knowledge about health insurance schemes, institutional constraints such as complex registration procedures, as well as premium costs and poor-quality services, all of which discourage enrolment or the reactivation of lapsed membership. There is thus a need for health insurance schemes, such as Kenya’s National Hospital Insurance Fund, to educate informal workers on insurance services and protocols and to improve services to encourage uptake and reduce default behaviour.     

Subjekt oder Subjektivation? Zur Kritik der Subjekttheorie von Andreas Reckwitz

Andreas Reckwitz postulates with his concept of subjectivation that the subject must be understood as a product of cultural practices, therefore losing his privileged status outside of the social context. Reckwitz operates with a sociological objectivism making regular behavior describable and explainable, as he documented in his study on different subject forms of modern times, which is underpinned with a large set of data. However, this is bought by cutting off essential characteristics of subjectivity: contingency and generation of meaning. This article therefore provides a critical analysis of the subjectivation assumption under normative and theoretical-methodological aspects. In doing so, the aim is to deduce a plea for the classical concept of subject from this critical analysis.     

Climate shocks and the timing of migration from Mexico

Although evidence is increasing that climate shocks influence human migration, it is unclear exactly when people migrate after a climate shock. A climate shock might be followed by an immediate migration response. Alternatively, migration, as an adaptive strategy of last resort, might be delayed and employed only after available in situ (in-place) adaptive strategies are exhausted. In this paper, we explore the temporally lagged association between a climate shock and future migration. Using multilevel event-history models, we analyze the risk of Mexico-US migration over a seven-year period after a climate shock. Consistent with a delayed response pattern, we find that the risk of migration is low immediately after a climate shock and increases as households pursue and cycle through in situ adaptive strategies available to them. However, about 3 years after the climate shock, the risk of migration decreases, suggesting that households are eventually successful in adapting in situ.     

Cross Cultural Programming for AIDS Orphans: What We are Learning from Other Contexts

The problem of AIDS orphans in Zambia has reached alarming proportions because of the extent of poverty and poor social and economic policies. Worldwide, 15 million children have been orphaned due to AIDS, with 11.6 million orphans in sub-Saharan Africa alone (UNICEF, The State of the World’s Children 2009: maternal and newborn health, UNICEF, New York, 2008), and 670,000 children under the age of 17 in Zambia (UNAIDS, UNAIDS report on the global AIDS epidemic, UNAIDS, Geneva, 2010). Resulting from this situation are child headed households (CHHs) who face hunger, poor health, sanitation and water problems. Despite the challenges, there seems to be an absence of political will to support CHHs. To assess if Africans living in Richmond Virginia in the United States might offer something programmatically useful for CHHs in Zambia, important elements in the Richmond Independent Living services model were identified. Specific elements were screened using Africans as a cultural screen. Important implications for programming and practice suggest that feasibility, content and quality are key areas for appropriate CHHs programming. In this article, the terms orphans, vulnerable children, and young people are used interchangeably.
