There is a growing deficit of rural surgeons, and preparation to meet this need is inadequate. More research into stratifying factors that specifically influence choice in rural versus urban practice is needed.

An institutional review board-approved survey related to factors influencing rural practice selection and increasing rural recruitment was distributed through the American College of Surgeons. The results were analyzed descriptively and thematically.

Of 416 respondents (74% male), 287 (69%) had previous rural experience. Of those, 71 (25%) did not choose rural practice; lack of professional or hospital support (30%) and lifestyle (26%) were the primary reasons. A broad scope of practice was most important among surgeons (52%), who chose rural practice without any previous rural experience. Over 60% of urban practitioners agreed that improved lifestyle and financial advantages would attract them to rural practice. The thematic analysis suggested institutional support, affiliation with academic insns for teaching, learning, and mentoring opportunities for rural surgeons could also lead to higher satisfaction, security, and potentially higher retention rate. These results provide a foundation to help focus specific efforts and resources in the recruitment and retention of rural surgeons.The aryl hydrocarbon receptor (AHR) has endogenous functions in mammalian vascular development and is necessary for mediating the toxic effects of a number of environmental contaminants. Studies in mice have demonstrated that AHR is necessary for the formation of the renal, retinal, and hepatic vasculature. In fish, exposure to the prototypic AHR agonist 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induces expression of the AHR biomarker cyp1a throughout the developing vasculature and produces vascular malformations in the head and heart. this website However, it is not known whether the vascular structures that are sensitive to loss of AHR function are also disrupted by aberrant AHR activation. Here, we report that TCDD-exposure in zebrafish disrupts development of 1) the subintestinal venous plexus (SIVP), which vascularizes the developing liver, kidney, gut, and pancreas, and 2) the superficial annular vessel (SAV), an essential component of the retinal vasculature. Furthermore, we determined that TCDD exposure increased the expression of bmp4, a key molecular mediator of SIVP morphogenesis. We hypothesize that the observed SIVP phenotypes contribute to one of the hallmarks of TCDD exposure in fish - the failure of the yolk sac to absorb. Together, our data describe novel TCDD-induced vascular phenotypes and provide molecular insight into critical factors producing the observed vascular malformations.Disappearing sea ice in the Arctic region results in a pressing need to develop oil spill mitigation techniques suitable for ice-covered waters. The uncertainty around the nature of an oil spill in the Arctic arises from the ice-covered waters and sub-zero temperatures, and how they may influence natural attenuation efficiency. The Sea-ice Environmental Research Facility was used to create a simulated Arctic marine setting. This paper focuses on the potential for biodegradation of the bulk crude oil content (encapsulated in the upper regions of the ice), to provide insight regarding the possible fate of crude oil in an Arctic marine setting. Cheaper and faster methods of chemical composition analysis were applied to the samples to assess for weathering and transformation effects. Results suggest that brine volume in ice may not be sufficient at low temperatures to encompass biodegradation and that seawater is more suitable for biodegradation.There is growing concern among governments around the world about the need to enhance the social and environmental performance of small and medium enterprises (SMEs), seen as key actors in efforts to achieve national sustainability goals. However, despite efforts made to promote their role in this area, SMEs still struggle to integrate social and environmental concerns into their business practices. Barriers that impede the integration of sustainable development in SMEs include a limited awareness of the impacts and benefits associated with sustainability, a lack of time and resources, and a lack of skills and expertise. The aims of this study are to examine the key collaborative roles that a range of stakeholders can play to support sustainability adoption in SMEs and to understand how these roles contribute to overcoming barriers to adoption. Building on thirteen case studies, this study found that stakeholders play five different and complementary collaborative roles in supporting sustainability practices within SMEs, namely that of trainer, analyst, coordinator, specialist, and financial provider. The study shows that these five roles can be performed by a wide range of local stakeholders and can contribute to overcoming different barriers to the integration of sustainability practices within SMEs. These findings demonstrate that one key way for governments to improve the sustainability performance of SMEs may be to facilitate and shape the development of stakeholder networks capable of performing these five critical roles as part of efforts to promote sustainability adoption within firms.The impact of ecological compensation policies on farmers' livelihoods is related to the sustainability of policies and social equity. How do different compensation methods affect farmers' livelihood assets? This paper uses China's Three-River-Source National Park System Pilot Area (TNP) as the research area, and designs three compensation scenarios cash subsidy, material supply, and technical training. We evaluated the impact of different compensation methods on the livelihood assets of farmers, and reveals the impact path of ecological compensation on different livelihood assets. The results show that cash subsidies can effectively improve the livelihood assets of farmers (17.04%), the five types of livelihood capital distribution are most reasonable under technical training method (0.306); Three compensation methods have improved the human assets of rural households (40.48%, 18.57%, and 0.48% respectively) and physical assets (30.15%, 26.84%, and 9.56% respectively). It also show different effects on farmers' financial assets (44.
