Introduction: Spreading proven or promising Aboriginal health programs and implementing them in new settings can make cost-effective contributions to a range of Aboriginal Australian development, health and wellbeing, and educational outcomes. Studies have theorized the implementation of Aboriginal health programs but have not focused explicitly on the conditions that influenced their spread. This study examined the broader political, institutional, social and economic conditions that influenced negotiations to transfer, implement, adapt, and sustain one Aboriginal empowerment program-the Family Wellbeing (FWB) program-to at least 60 geographical sites across Australia over 24 years...

Background: Adjusting to the challenges of a chronic illness does not affect patients alone but also influences social network members-most notably spouses. One interpersonal framework of coping with a chronic illness is communal coping, described as when a problem is appraised as joint and the couple collaborates to manage the problem. Purpose: We sought to determine whether daily communal coping was linked to daily mood and self-care behavior and examined one potential mechanism that may explain these links: perceived emotional responsiveness...

Introduction: Generating country-level political commitment will be critical to driving forward action throughout the United Nations Decade of Action on Nutrition (2016-2025). In this review of the empirical nutrition policy literature, we ask: what factors generate, sustain and constrain political commitment for nutrition, how and under what circumstances? Our aim is to inform strategic 'commitment-building' actions. Method: We adopted a framework synthesis method and realist review protocol...

In many contexts there are a range of individuals and organisations offering healthcare services that differ widely in cost, quality and outcomes. This complexity is exacerbated by processes of healthcare commercialisation. Yet reliable information on healthcare provision is often limited, and progress to and through the healthcare system may depend on knowledge drawn from prior experiences, social networks and the providers themselves. It is in these contexts that healthcare brokerage emerges and third-party actors facilitate access to healthcare...

BACKGROUND: Generalists such as general practitioners and district nurses have been the main actors in community palliative care in Norway. Specialised oncology nurses with postgraduate palliative training are increasingly becoming involved. There is little research on their contribution. This study explores how general practitioners (GPs) and oncology nurses (ONs) experience their collaboration in primary palliative care. METHODS: A qualitative focus group and interview study in rural Northern Norway, involving 52 health professionals...

Understanding patterns of participation in private lands conservation, which is often implemented voluntarily by individual citizens and private organizations, could improve its effectiveness at combating biodiversity loss. We used social network analysis (SNA) to examine participation in conservation development (CD), a private land conservation strategy that clusters houses in a small portion of a property while preserving the remaining land as protected open space. Using data from public records for six counties in Colorado, USA, we compared CD participation patterns among counties and identified actors that most often work with others to implement CDs...

Numerous studies have investigated the remarkable variation of social features and the resulting structures across species. Indeed, relationships are dynamic and vary in time according to various factors such as environmental conditions or individuals attributes. However, few studies have investigated the processes that stabilize the structures within a given species, and the behavioral mechanisms that ensure their coherence and continuity across time. Here, we used a dynamic actor-based model, RSiena, to investigate the consistency of the temporal dynamic of relationships of a group of captive rooks facing recurrent modifications in group composition (i...

This article examines the role of national actors articulated with an explicitly counter-hegemonic transnational knowledge network (TKN) mobilising around social medicine in policy debates on population control and family planning. It focuses primarily on Brazil, using Mexico as a shadow case to highlight salient points of contrast. In doing so, it makes two contributions to larger debates about TKNs. First, it highlights the plural and contested nature of the knowledge production they enact, underscoring contestation around a global reproductive regime that consolidated around family planning...

BACKGROUND: Purinergic signaling accounts for a complex network of receptors and extracellular enzymes responsible for the generation, recognition and degradation of extracellular ATP and adenosine. The main actors of this system include P2X, P2Y and Adenosine Receptors, ectonucleotidases CD39 and CD73 and Adenosine Deaminase. The purinergic network recently emerged as a central player in several physiopathological conditions particularly those linked to immune system regulation including type 1 and type 2 diabetes...

ETHNOPHARMACOLOGICAL RELEVANCE: Ophiocordyceps sinensis (Berk.) G.H.Sung, J.M.Sung, Hywel-Jones & Spatafora, a high altitude Himalayan fungus-caterpillar product found in alpine meadows in China, Bhutan, Nepal, and India, has been used in the Traditional Chinese Medicine system for over 2000 years. Heightened demand in China over the past 15 years, coupled with limited production, has led to a price hike and increased economic importance of harvests to rural households throughout the species' range...

Recent network research indicates that native youth prefer to befriend immigrants with stronger rather than weaker host country identification. Surprisingly, however, no respective preference of high-identifying immigrants for native friends has been found, and there is little evidence that friends influence immigrants' identification. Seeking to make sense of these unexpected findings, my aims are twofold: First, I reproduce an earlier study using three waves of newly collected network panel data. Second, going beyond a robustness test with better data, I suggest that relative group size within school accounts for earlier findings...

For sexually transmitted infections like HIV to propagate through a population, there must be a path linking susceptible cases to currently infectious cases. The existence of such paths depends in part on the degree distribution. Here, we use simulation methods to examine how two features of the degree distribution affect network connectivity: Mean degree captures a volume dimension, while the skewness of the upper tail captures a shape dimension. We find a clear interaction between shape and volume: When mean degree is low, connectivity is greater for long-tailed distributions, but at higher mean degree, connectivity is greater in short-tailed distributions...

The development and implementation of innovation by healthcare providers is understood as a multi-determinant and multi-level process. Theories at different analytical levels (i.e. micro and organisational) are needed to capture the processes that influence innovation by provide. This article combines a micro theory of innovation, actor-network theory, with organisational level processes using the 'resource based view of the firm'. It examines the influence of, and interplay between, innovation-seeking teams (micro) and underlying organisational capabilities (meso) during innovation processes...

Successful management of complex social-ecological landscapes overlapping Natura 2000 sites requires collaboration between various actors such as law enforcement agencies, NGOs and enterprises. Natura 2000 governance is stimulated by central actors (e.g., Natura 2000 administrators), with successes and failures of management activities depending on the capacity of the network leader to implement a collaborative approach to environmental governance. By using social network analysis, we analysed the cooperation, information flow and capacity for collective action within Natura 2000 governance networks within two Romanian protected areas: Lower Siret Floodplain and Iron Gates Natural Park...

The article applies actor network theory (ANT) to autobiographical data on alcohol dependence to explore what ANT can offer to the analysis of 'addiction stories'. By defining 'addiction' as a relational achievement, as the effect of elements acting together as a configuration of human and non-human actors, the article demonstrates how the moving and changing attachments of addiction can be dynamically analyzed with concepts of 'assemblage', 'mediator', 'tendency', 'translation', 'trajectory', 'immutable mobile', 'fluid' and 'bush fire'...

The survival strategies of migrant women living in urban poverty are embedded in urban food landscapes ('foodscapes') characterized by dynamic social relationships and mobility. Relying on interviews with 31 migrant women in Washington, DC, this paper traces the socio-spatial conditions of their urban foodscapes to show that urban environments inhabited by low-income migrants are dynamic, stretching across multiple neighborhoods as they move throughout the city with social networks to obtain affordable, quality, and culturally appropriate food...

Purpose Carrying out minor surgery procedures in the primary care setting is popular with patients, cost effective and delivers at least as good outcomes as those performed in the hospital setting. This paper aims to describe the central role of clinical leadership in developing an accreditation system for general practitioners (GPs) undertaking community-based surgery in the Irish national setting where no mandatory accreditation process currently exists. Design/methodology/approach In all, 24 GPs were recruited to the GP network...

There has been increasing attention to and investment in local environmental stewardship in conservation and environmental management policies and programs globally. Yet environmental stewardship has not received adequate conceptual attention. Establishing a clear definition and comprehensive analytical framework could strengthen our ability to understand the factors that lead to the success or failure of environmental stewardship in different contexts and how to most effectively support and enable local efforts...

This study reviews and synthesizes empirical research literature focusing on the relationship between boards of directors and organizational effectiveness of U.S. hospitals. The study examines literature published in scholarly journals during the period of 1991-2017. Fifty-one empirical articles were identified that met the study's inclusion criteria. A framework from the corporate governance and nonprofit governance literature is used to classify the articles according to level of analysis (individual actors, governing bodies, organizations, and networks, alliances and multiorganizational initiatives) and focus of research (formal structure and behavioral dynamics-including informal structures and processes)...
