Terrestrialization, Miniaturization and Rates of Diversification in African Puddle Frogs (Anura: Phrynobatrachidae)

Terrestrialization, the evolution of non-aquatic oviposition, and miniaturization, the evolution of tiny adult body size, are recurring trends in amphibian evolution, but the relationships among the traits that characterize these phenomena are not well understood. Furthermore, these traits have been identified as possible “key innovations” that are predicted to increase rates of speciation in those lineages in which they evolve. We examine terrestrialization and miniaturization in sub-Saharan puddle frogs (Phrynobatrachidae) in a phylogenetic context to investigate the relationship between adaptation and diversification through time. We use relative dating techniques to ascertain if character trait shifts are associated with increased diversification rates, and we evaluate the likelihood that a single temporal event can explain the evolution of those traits. Results indicate alternate reproductive modes evolved independently in Phrynobatrachus at least seven times, including terrestrial deposition of eggs and terrestrial, non-feeding larvae. These shifts towards alternate reproductive modes are not linked to a common temporal event. Contrary to the “key innovations” hypothesis, clades that exhibit alternate reproductive modes have lower diversification rates than those that deposit eggs aquatically. Adult habitat, pedal webbing and body size have no effect on diversification rates. Though these traits putatively identified as key innovations for Phrynobatrachus do not seem to be associated with increased speciation rates, they may still provide opportunities to extend into new niches, thus increasing overall diversity

The effects of integrated care: a systematic review of UK and international evidence

BACKGROUND: Healthcare systems around the world have been responding to the demand for better integrated models of service delivery. However, there is a need for further clarity regarding the effects of these new models of integration, and exploration regarding whether models introduced in other care systems may achieve similar outcomes in a UK national health service context. METHODS: The study aimed to carry out a systematic review of the effects of integration or co-ordination between healthcare services, or between health and social care on service delivery outcomes including effectiveness, efficiency and quality of care. Electronic databases including MEDLINE; Embase; PsycINFO; CINAHL; Science and Social Science Citation Indices; and the Cochrane Library were searched for relevant literature published between 2006 to March 2017. Online sources were searched for UK grey literature, and citation searching, and manual reference list screening were also carried out. Quantitative primary studies and systematic reviews, reporting actual or perceived effects on service delivery following the introduction of models of integration or co-ordination, in healthcare or health and social care settings in developed countries were eligible for inclusion. Strength of evidence for each outcome reported was analysed and synthesised using a four point comparative rating system of stronger, weaker, inconsistent or limited evidence. RESULTS: One hundred sixty seven studies were eligible for inclusion. Analysis indicated evidence of perceived improved quality of care, evidence of increased patient satisfaction, and evidence of improved access to care. Evidence was rated as either inconsistent or limited regarding all other outcomes reported, including system-wide impacts on primary care, secondary care, and health care costs. There were limited differences between outcomes reported by UK and international studies, and overall the literature had a limited consideration of effects on service users. CONCLUSIONS: Models of integrated care may enhance patient satisfaction, increase perceived quality of care, and enable access to services, although the evidence for other outcomes including service costs remains unclear. Indications of improved access may have important implications for services struggling to cope with increasing demand. TRIAL REGISTRATION: Prospero registration number: 42016037725

Everyday Making through Facebook Engagement: Young Citizens’ Political Interactions in Australia, the United Kingdom and the United States

The emergence of personalised, interactive forms of social media has led to questions about the use of these platforms for engagement in politics. Existing research focuses on whether political actors successfully engage citizens, and how social media platforms mobilise young people into offline participation. In this article, we present original survey data on how many young people use social media to do politics: share information, express themselves, and take action. Everyday Facebook use is underpinned by young people’s engaged citizenship norms, and it has the potential to mobilise a broader range of young people. We contextualise the survey findings with qualitative analysis of how young people describe their willingness to engage in politics on social media. There is a general reluctance to take political action due to the possibility of conflict and disagreement within their networks; however, some acknowledge it is a way to bring the disengaged into political debate

Examining the role of ideological and political education on university students’ civic perceptions and civic participation in Mainland China: Some hints from contemporary citizenship theory

A long existing compulsive curriculum of ideological and political education is employed by the Chinese government to promote citizenship education among Chinese university students. This article builds on the findings of a mixed-methods research that examined the role of ideological and political education on university students’ civic perceptions and civic participation. The results showed little evidence of this curriculum having a clear effect on students’ political participation such as voting, as well as their idealized broad civic participation, but did reveal relatively positive effects on students’ civic intention and civic expression. In addition, it also identified its significant role in organizing students towards attending party-related activities. It shows that ideological and political education is insufficient to achieve specified aims of citizenship education among Chinese university students. We then argue that it results from a mechanistic understanding of citizenship and participation in educational policies and structural barriers to young people’s formal participation. Hence, this article argues that the forms and contents of citizenship education in China need to be reconsidered beyond the limits of the current ideological and political education and that the analyses contributed to an argument for a broader approach to citizenship education to be developed and adopted

Digital Divides revisited: What is new about divides and their research?

This article critically reviews well-established and recent trends in digital divides literature and research, bringing up new elements of divides and the related research and making recommendations about future research. First, it disentangles some aspects of the puzzling nature and ongoing importance of digital divides. It then discusses how the concept of digital divides has evolved over the last two decades and how research literature has examined it in the same period on the basis of different attempts at contextualisation. The article brings together theoretical and empirical insights and suggests that digital divides be revisited so as to illustrate the need for less linear and more properly contextualised approaches to the concept and phenomenon of digital divides where technology, society and politics will be jointed taken into consideration to explain divides. It specifically proposes that digital divides and their research be revisited so as to emphasise the critical role of socio-cultural and decision-making dynamics in structuring the adoption of ICT in both qualitative and quantitative terms. Thus, it argues that the web of cultural traits in a society, with their own gaps and disparities, as well as policy and regulation dynamics, are in a constant dialogue with technology, together influencing digital divides and entailing implications for other forms of divisions in society
