Mangrove forests store high densities of carbon across the tropical urban landscape of Singapore

Tropical forested ecosystems provide multiple ecosystem services to rural and urban landscapes, with carbon storage gaining particular attention. Deforestation due to rural-urban transitions may lead to a reduction in carbon storage ability. Coastal mangrove forests are particularly at risk from deforestation due to their location in the rapidly urbanizing coastal zone, and the city state of Singapore is an extreme example, losing as much as 90 % of its original mangrove cover due to land reclamation and reservoir construction. Knowledge of mangrove ecosystem services may allow better conservation, restoration and incorporation of remaining mangrove patches into the urban landscape. Focusing on the regulating ecosystem service of carbon storage, mangrove carbon stocks have been estimated for Singapore using a combination of field and remote sensing techniques. Biomass carbon showed substantial spatial variation, with old, contiguous mangrove patches containing a higher density of biomass carbon than fragmented, river-fringing or restored mangroves. In total, national biomass carbon equated to 116,117.1 megagrams of carbon (Mg C), and a coarse estimate of the total carbon stock (including soil carbon) suggests that Singapore’s mangroves may store 450,571.7 Mg C. While lower than other regional estimates focused on natural, oceanic mangroves, this is a significant carbon stock for a disturbed, urban mangrove system, and may be equivalent to the average annual carbon emissions of 621,000 residents. This analysis, alongside a review of other urban forest studies, highlights the importance of forested ecosystems such as mangroves in providing a carbon storage ecosystem service to urban areas.     

Loss of Control as a Discriminating Factor Between Different Latent Classes of Disordered Gambling Severity

Analyses of disordered gambling assessment data have indicated that commonly used screens appear to measure latent categories. This stands in contrast to the oft-held assumption that problem gambling is at the extreme of a continuum. To explore this further, we report a series of latent class analyses of a number of prevalent problem gambling assessments (PGSI, SOGS, DSM-IV Pathological Gambling based assessments) in nationally representative British surveys between 1999 and 2012, analysing data from nearly fifty thousand individuals. The analyses converged on a three class model in which the classes differed by problem gambling severity. This identified an initial class of gamblers showing minimal problems, a additional class predominantly endorsing indicators of preoccupation and loss chasing, and a third endorsing a range of disordered gambling criteria. However, there was considerable evidence to suggest that classes of intermediate and high severity disordered gamblers differed systematically in their responses to items related to loss of control, and not simply on the most ‘difficult’ items. It appeared that these differences were similar between assessments. An important exception to this was one set of DSM-IV criteria based analyses using a specific cutoff, which was also used in an analysis that identified an increase in UK problem gambling prevalence between 2007 and 2010. The results suggest that disordered gambling has a mixed latent structure, and that present assessments of problem gambling appear to converge on a broadly similar construct.     

Impact of metabolic syndrome and its components on kidney stone in aging Taiwanese males

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.

Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.

Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?p?Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone.     

Kontexteffekte in Familien – Angleichung von Paaren und intergenerationale Transmission am Beispiel Religiosität

The present contribution shows conceptual and methodological approaches for the study of social context effects within families. Family members mutually constitute the social context in which family behavior and personality development take place. Social influence in families becomes evident empirically in family members’ significant similarity concerning a wide variety of characteristics. The present study focuses on intrafamily convergence with regard to religiousness. In an empirical illustration, both (a) horizontal intracouple alignment and (b) vertical intergenerational transmission processes are examined. Besides the finding that experiences during religious socialization in the parental home have a stronger impact than partner influences in adulthood, our analyses show that social context effects are more pronounced the stronger the cohesion of the respective interaction dyad is (e.g., according to measures of relationship quality).     

Physician Migration in the Global South between Cuba and South Africa

Transnational physician migration has concerned states' health and migration policies for many years. Recent developments have increased attention to the outcomes of these flows in the global south, where physician emigration is undermining public health policies. Cuba's exporting of medical professionals presents an alternative dynamic, based upon both an ideology of humanitarian solidarity and a need to secure hard currency earnings. The benefits and challenges arising from a bilateral agreement between Cuba and South Africa to supply Cuban doctors to South Africa and training at the Latin American Medical School (ELAM) for South African medical students are addressed. The benefits of skills enhancement and professional development are noted, as well as the economic benefits for both the Cuban government and individual doctors, while concerns with the appropriateness of the medical training provided at ELAM for the South African health context and the sustainability of the current policy are discussed.

Policy Implications

• Strategic bi‐lateral agreements offer a productive route towards more sustainable management of skilled migration.
• When migration agreements include skills training, attention is needed to ensure the training provided is appropriate to the destination context: attention needs to be paid to the appropriateness of the medical training afforded to South African medical students in Cuba for health requirements in South Africa.
• International migration agreements can form part of a broader policy suite aimed at realizing public health and other development priorities. However, attention must be paid to the suitability and sustainability of the outcomes of these practices.

     

The Virtues of Participation without Power: Campaigns,Party Networks,and the Ends of Politics

Following Francesca Polletta's call to reconsider participatory democracy in a new millennium, this article analyzes and makes a normative case for institutional and partisan forms of participation without decision making. I draw on field research and interviews conducted over the last decade on Democratic Party campaigns to argue against contemporary denunciations of partisanship and critiques of institutional participation by radical democrats. First, this article discusses the opportunities available for citizens to participate in electoral politics. Volunteering is often limited to fund‐raising and instrumental voter contacts given the constraints of electoral institutions. Although campaign volunteerism is a fundamentally limited form of civic engagement, institutional and partisan participation has democratic value. Campaigns are institutionally linked to political parties that offer distinct moral, ideological, and policy choices to citizens. Recent analytical and empirical work shows that contemporary political parties are constituted by relatively coherent networks of civil society and social movement organizations that devote considerable resources to electoral politics to shape primary and general election outcomes and advance their agendas in governance. This reveals electoral participation to be tightly linked to larger partisan dynamics and institutional sites of power.     

The Development of a Reliable Change Index and Cutoff for the Revised Dyadic Adjustment Scale

The Revised Dyadic Adjustment Scale (RDAS; Busby, Crane, Larson, & Christensen, 1995) is a measure of couple relationship adjustment that is often used to differentiate between distressed and non‐distressed couples. While the measure currently allows for a determination of whether group mean scores change significantly across administrations, it lacks the ability to determine whether an individual's change in dyadic adjustment is clinically significant. This study addresses this limitation by establishing a cutoff of 47.31 and reliable change index of 11.58 for the RDAS by pooling data across multiple community and clinical samples. An individual whose score on the RDAS moves across the cutoff changes by 12 or more points can be classified as experiencing clinically significant change.     

Socio-psychological barriers for peace making and ideas to overcome them / Barreras sociopsicológicas para la paz e ideas para superarlas

Intensive and violent intergroup conflicts that rage in different parts of the world are real. These conflicts center over disagreements focusing on contradictory goals and interests in different domains and must be addressed in conflict resolution. It is well known that the disagreements could potentially be resolved if not the powerful socio-psychological barriers which fuel and maintain the conflicts. These barriers inhibit and impede progress towards peaceful settlement of the conflict. They stand as major obstacles to begin the negotiation, to continue the negotiation, to achieve an agreement and later to engage in a process of reconciliation. These barriers are found among both leaders and society members that are involved in vicious, violent and protracted intergroup conflicts. They pertain to the integrated operation of cognitive, emotional and motivational processes, combined with a pre-existing repertoire of rigid supporting beliefs, world views and emotions that result in selective, biased and distorted information processing. This processing obstructs and inhibits the penetration of new information that can potentially contribute to facilitating progress in the peace-making process. The paper elaborates on the nature of the socio-psychological barriers and proposes preliminary ideas of how to overcome them. These ideas focus on the unfreezing process which eventually may lead to cessation of adherence to the repertoire that supports the continuation of the conflict, its evaluation and arousal of the readiness to entertain of alternative beliefs that support peace making.
