Trends in cardiovascular diseases and associated risks in sub-Saharan Africa: a review of the evidence for Ghana,Nigeria, South Africa,Sudan and Tanzania

Background: Sub-Saharan Africa (SSA) countries are facing an epidemiological shift from infectious disease to chronic diseases, such as cardiovascular diseases (CVDs). CVDs incidence in SSA are frequently attributed to the prevalence of hypertension, diabetes, and overweight/obesity. Nevertheless, some researchers contend that CVDs are not a priority public health problem in SSA.

Method: This paper systematically reviews the evidence on CVDs and their relation with hypertension, diabetes mellitus and obesity/overweight in Ghana, Nigeria, South Africa, Sudan and Tanzania. The publication’s content was analyzed qualitatively using the directed content analysis method and the results were presented in a tabular format.

Result: The paper illustrates the rising prevalence of CVDs as well as the three related risk conditions in the selected SSA countries.

Conclusion: The review indicates a poor health system response to the increasing risk of CVDs in SSA. The conditions and major drivers that contribute to this underlying increasing trend need to be further studied.     

Homemaking on the streets and beyond

Homemaking is associated with domiciled family life, community, and secure work. Moving beyond this perspective, we explore the experiences of people dislocated from family, community, and work, and their efforts to make a place for themselves. We consider a homeless man's efforts to make a home on the streets of Auckland in the absence of positive social ties, employment, and a domiciled abode. This case draws upon an auto-biographical interview, three photo-production projects and three photo-elicitation interviews with Daniel. We consider Daniel's profound sense of loneliness and efforts at imagining a domiciled home beyond the streets where he can forge meaningful relationships. Daniel is now re-housed, in part, as a result of insights from this research being used in social work practice.     

Where It's At! The Role of Best Friends and Peer Group Members in Young Adults' Alcohol Use

We examined the hypothesis that best friends and members from a broader peer group would not differ in the amount of influence they have on young adults' alcohol consumption and that what counts would be the mere presence of drinking peers in a given context—irrespective of the type of relationship such peers would have with the target young adult. Data were used from a naturalistic observation study that was conducted in a “bar‐lab” among 221 young adults aged 18–25 years. Both hierarchical and multilevel regression analyses showed that group effects (i.e., average group levels of alcohol consumption) explained young adults' drinking. When taking into account these group effects, best friends' alcohol consumption in the bar‐lab was a nonsignificant predictor of young adults' alcohol use—although best friends' questionnaire‐assessed drinking did predict alcohol consumption in the bar‐lab.     

Valuation of road safety effects in cost–benefit analysis

Cost–benefit analysis is a common method for evaluating the social economic impact of transport projects, and in many of these projects the saving of human lives is an issue. This implies, within the framework of cost–benefit analysis, that a monetary value should be attached to saving human lives. This paper discusses the ‘Value of a Statistical Life’ (VoSL), a concept that is often used for monetising safety effects, in the context of road safety. Firstly, the concept of ‘willingness to pay’ for road safety and its relation to the VoSL are explained. The VoSL approach will be compared to other approaches to monetise safety effects, in particular the human capital approach and ‘quality adjusted life years’. Secondly, methods to estimate the VoSL and their applicability to road safety will be discussed. Thirdly, the paper reviews the VoSL estimates that have been found in scientific research and compares them with the values that are used in policy evaluations. Finally, a VoSL study in the Netherlands will be presented as a case study, and its applicability in policy evaluation will be illustrated.     

The effects of direct experience on consumer product evaluation

The effects of different sales strategies on consumer product evaluation were investigated. It was expected that direct product experience could decrease economic product valuation. Experiments 1 and 2 studied the effects of product trials and money-back guarantees on consumer willingness to pay (WTP). It appeared that WTP was significantly lower after a product trial than with a money-back guarantee or normal sale. In Experiment 3 a structural equation model showed that product trials had a positive effect on attitude toward the product. Also, a negative effect on WTP was found when the effect was measured directly, but a positive effect when the effect was measured indirectly (through attitude).     

Perception and Communication of Flood Risks: A Systematic Review of Empirical Research

Flood hazards are the most common and destructive of all natural disasters. For decades, experts have been examining how flood losses can be mitigated. Just as in other risk domains, the study of risk perception and risk communication has gained increasing interest in flood risk management. Because of this research growth, a review of the state of the art in this domain is believed necessary. The review comprises 57 empirically based peer‐reviewed articles on flood risk perception and communication from the Web of Science and Scopus databases. The characteristics of these articles are listed in a comprehensive table, presenting research design, research variables, and key findings. From this review, it follows that the majority of studies are of exploratory nature and have not applied any of the theoretical frameworks that are available in social science research. Consequently, a methodological standardization in measuring and analyzing people's flood risk perceptions and their adaptive behaviors is hardly present. This heterogeneity leads to difficulties in comparing results among studies. It is also shown that theoretical and empirical studies on flood risk communication are nearly nonexistent. The article concludes with a summary on methodological issues in the fields of flood‐risk perception and flood‐risk communication and proposes an agenda for future research.     

Confronting or Complementing? A Case Study on NGO–State Relations from Kerala, India

NGOs have, of late, found some of their traditional domains, such as provision of micro-credit and participatory development, coinciding with or being taken away by the state. How do they position themselves and retain relevance vis-a-vis the state in the changed scenario? Tracing the trajectory of interventions of a local NGO in Kerala, India, this article shows that NGOs exhibit ‘multiple identities’—selective collaboration, gap-filling and posing alternatives—in the process of engagement with the state. The ‘strategizing’ of such identities may hold the key to their relevance vis-a-vis the state.     

Innovation Systems and Systems Development:Innovation Systems and Systems Development:Lessons from History and Prospects for the Future

This paper addresses the question What drives economic growth from a socio-technical perspective.It discusses the concept ofinnovation system,especially at the national level,and its three components: actors and factors,interrelationships and dynamics.Historical examples will be given from eighteenth century England (especially the Watt-Boulton steam engine firm) and the late nineteenth and early twentieth century USA (especially the contribution of Thomas Edison).Lessons are drawn for China,focusing on Har...
