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.     

Reflective Photobooth – a way to visualise,and challenge perceptions and representations of distanced social groups

Taken-for-granted knowledge about people from other social groups is a key challenge for overcoming stereotypes. This article describes a novel arts-based research method to visualise participants’ frames of distanced social groups and aims to trigger reflections among them. The Reflective Photobooth invites participants to dress up as members of distanced social groups, stage a scene, produce pictures, answer prompting questions, and discuss their visualisations. We argue that the artistic re-enactment that underlies the visualisation process can attract diverse groups of participants to engage with research topics, create places for the articulation of critical statements against existing societal clichés and stereotypical media representations, and trigger reflections among participants about taken-for-granted knowledge. The method was tested within the Frame-a-Farmer project, in which the social distance between consumers and food producers in modern agrifood systems was addressed. Results indicate that despite the method bearing some risks and facing some challenges, three promising areas of future application could be identified: (i) raising awareness among large groups of people, (ii) collecting stories or topical vignettes, and (iii) deconstructing taken-for-granted knowledge and societal clichés.     

Two preprocessing algorithms for climate time series

We propose two preprocessing algorithms suitable for climate time series. The first algorithm detects outliers based on an autoregressive cost update mechanism. The second one is based on the wavelet transform, a method from pattern recognition. In order to benchmark the algorithms'' performance we compare them to existing methods based on a synthetic data set. Eventually, for exemplary purposes, the proposed methods are applied to a data set of high-frequent temperature measurements from Novi Sad, Serbia. The results show that both methods together form a powerful tool for signal preprocessing: In case of solitary outliers the autoregressive cost update mechanism prevails, whereas the wavelet-based mechanism is the method of choice in the presence of multiple consecutive outliers.     

Super-diversity and the art of living in ethnically concentrated urban areas

This article discusses how local diversity is being experienced by Somali immigrants who have previously lived in the Netherlands and are now residing in London. It explores the various challenges and potential advantages of living in homogenous urban areas within a super-diverse city and focuses on three situations: (1) when homogeneity is functional and leads to living in parallel worlds; (2) when homogeneity creates social reproduction, even when located in a super-diverse city; and (3) when people manage to oscillate between both worlds – i.e. between homogenous urban areas and the potential offered by a super-diverse city. The article argues that migrants trace different pathways in the context of super-diversity. They have the ability to operate at different scales – the locale and the cosmopolitan super-diverse metropolis. However, the most vulnerable people have more difficulty in accessing and benefiting directly from the potential offered by super-diversity.     

Re‐conceptualising the link between research and practice in social work: A literature review on knowledge utilisation

Despite the recent movement towards greater research use in many areas of social work, criticisms persist that decision making in practice is seldom informed by sound research evidence. Discourse about the research‐to‐practice gap in social work has tended to focus on the feasibility of evidence‐based practice for the profession, but has rarely drawn from the broader knowledge utilisation literature. There are important understandings to be gained from the knowledge utilisation field, which spans more than six decades of interdisciplinary research.This article introduces the wider knowledge utilisation literature to a social work audience. It considers the potential of this body of literature to facilitate research use in social work, as well as conceptual issues that may be hindering it from informing improvements to research utilisation in practice.     

Neighborhood change within the Canadian ethnic mosaic, 1986–1991

This paper examines the neighborhoodpatterns in three major Canadian metropolitan areasbetween 1986 and 1991. Data are obtained from 1986 and1991 profile census files and two Special Tabulationsof 1986 and 1991 Canadian census. The data indicatethat the first pathway of neighborhood change is thediversification that takes place among charter-onlyneighborhoods with the introduction of a sizableEuropean presence, followed by Asians and then blacks. The second pathway featuring racial uniformityprimarily takes place in multi-ethnic neighborhoodscontaining one or more visible minority groups. Multivariate analysis suggests that the increase inracial and ethnic diversity in neighborhoods isrelated to the efforts of visible minorities,especially Asians, seeking out neighborhoods withEuropeans.     

National survey on lifestyles and gambling in Serbia: gambling participation and problem gambling in adult population

The aim was to examine the association of socio-demographic and lifestyle characteristics with gambling severity level. The study was a part of the National Survey on Lifestyles in Serbia: Substance Abuse and Gambling, in 2014. The sample consisted of 5385 individuals. Based on the Problem Gambling Severity Index (PGSI) score participants were divided into non-problem gambling, low-/moderate-risk gambling and problem gambling. Prevalence of problem gambling was 0.5%, which was associated with having poor self-perceived financial status, having moderate or high risk for psychological distress, playing sports betting, casino games and slot machines. Low/moderate gambling was associated with having poor self-perceived financial status, number of drinking days per year, using any illicit drugs in the last 30 days, playing sports betting, slot machines, and online betting. Programmes of early detection of problem gambling should be developed, and regulation of availability of slot machines and sports betting.     

Principals and Agents: An Investigation of Executive Compensation in Human Service Nonprofits

This study proposes a revised agency theory for the nonprofit sector, distinguishes between the extent of agency and the extent of monitoring, and compares the magnitudes of the two impacts. Using panel data for 1998–2003, the paper tests whether monitoring by principal-stakeholders such as donors, clients, the government, and the board reduces the opportunity for executive misconduct such as extravagant spending on compensation and perquisites. Given the theory, the findings show that two effects influence CEO salaries. First, while nonprofit endowments provide a fiscal cushion in tough financial situations, by offering “organizational slack” they also increase the CEO’s opportunity to steal or raise her compensation (i.e., agency effect). Second, donors utilize monitoring mechanisms such as auditing or direct observations, which limit the opportunity for misconduct and reduce executive pay (i.e., monitoring effect). In the final analysis, the monitoring effect is greater than the agency effect, which implies that even if agency problems are present, the monitoring that donors provide offsets them.     

Beyond the Activist Ghetto: A Deductive Blockmodelling Approach to Understanding the Relationship between Contact with Environmental Organisations and Public Attitudes and Behaviour

Current research on the behavioural impacts of social movements tends to focus on their influence on those most intensely involved. Consequently it overlooks the impacts that social movement organisations might have on those outside the activist ghetto. To begin to address this gap in the literature, this article examines the relationship between contact with environmental organisations and public attitudes and behaviour. Monitoring the electricity use of 72 households has facilitated analysis of its association with their environmental attitudes and contact with environmental organisations. Although standard statistical approaches fail to uncover a relationship between contact with environmental organisations and attitudes and behaviour, a deductive blockmodelling approach tells a different story. Low household electricity use is associated with households sharing pro-environmental attitudes and contact with environmental organisations. High energy use is associated with households not sharing any of these; and moderate energy use is associated with a moderate degree of sharing. Our findings reveal the need for systematic studies of environmental movement organisations' impact on the public's pro-environmental behaviours.
