ESC: Edge-attributed Skyline Community Search in Large-scale Bipartite Graphs

Due to the ability of modeling relationships between two different types of entities, bipartite graphs are naturally employed in many real-world applications. Community Search in bipartite graphs is a fundamental problem and has gained much attention. However, existing studies focus on measuring the structural cohesiveness between two sets of vertices, while either completely ignoring the edge attributes or only considering one-dimensional importance in forming communities. In this paper, we introduce a novel community model, named edge-attributed skyline community (ESC), which not only preserves the structural cohesiveness but unravels the inherent dominance brought about by multi-dimensional attributes on the edges of bipartite graphs. To search the ESCs, we develop an elegant peeling algorithm by iteratively deleting edges with the minimum attribute in each dimension. In addition, we also devise a more efficient expanding algorithm to further reduce the search space and speed up the filtering of unpromising vertices, where a upper bound is proposed and proven. Extensive experiments on real-world large-scale datasets demonstrate the efficiency, effectiveness, and scalability of the proposed ESC search algorithms. A case study was conducted to compare with existing community models, substantiating that our approach facilitates the precision and diversity of results

Barriers to adherence to standard precautions among community health workers: A scoping review

Aim: This review aims to map available evidence on the adherence level and barriers to standard precautions among home-based community health workers. Methods: A scoping review using the JBI protocol searched multiple databases (Medline, CINAHL, PsycINFO and Web of Science) as well as Google Scholar for published articles on standard precaution practices of community health workers during home visits. Search terms included “standard precautions”, “guideline adherence”, “community health” and “home care”. Two-stage screening (title/abstract and full-text) was conducted to select relevant articles. Results: Eight eligible studies yielded three major themes: home environment context, individual factors and organisational factors. Findings indicated low adherence to standard precautions in home care, attributed to factors such as home layout, family or pet interference, cleanliness, limited access to protective equipment (e.g. gloves) and personal protective equipment allergies. Conclusion: Providing healthcare at home is challenging, impacting care quality. Further studies on standard precautions in home care can improve adherence, quality of care and patient outcomes

Analysis and Comparison of P2P Search Methods

The popularity and bandwidth consumption attributed to current Peer-to-Peer file-sharing applications makes the operation of these distributed systems very important for the Internet community. Efficient object discovery is the first step towards the realization of distributed resource-sharing. In this work, we present a detailed overview of recent and existing search methods for unstructured Peer-to-Peer networks. We analyze the performance of the algorithms relative to various metrics, giving emphasis on the success rate, bandwidth-efficiency and adaptation to dynamic network conditions. Simulation results are used to empirically evaluate the behavior of nine representative schemes under a variety of different environments

Identifying the Implications of most Warming Foods: A Pilot Analysis

The new found popular interest in sustainable development is highly skewed towards areas that are politically visible, such as transport and in particular the evils of air travel. This situation is mirrored in the academic community with an explosion of articles on sustainable transport (an EBSCO web search yielded 552 academic references to Sustainable Transport while for example Sustainable Livestock only found less than 10% of that number1). Nonetheless, only 14% of GHG’s actually result from transport, with as little as 2% coming from aviation, against 32% resulting from agriculture and land use – a major part of which can be directly attributed to the food chain (Stern, 2006). Moreover within the food system, certain areas such as livestock production are particularly problematic with meat and dairy products contributing more than 50% of the total GHG’s emitted (Kramer et al, 1999). Another recent study in the UK shows that GHG emissions attributable to meat and dairy consumption are about 4 times more than the GHG emissions generated from fruit and vegetable consumption (Garnett, 2007).Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety, Industrial Organization,

Critique of Ifeanyi Menkiti’s Idea of Person and Community

We are in a society where its system permits an individual to take precedence over a group community the reason why we often put wealth above good character In Africa some scholars text and philosophers have attributed this social woe on imperial influx that took over African traditional institution around 19th century In his quest to search for socio-cultural metaphysical epistemic and moral constituents of a person Ifeanyi Menkiti a prolific African philosopher gave a turgid articulation on the Person and Community in African Traditional Thought with a sharp position that a community group takes precedence over a person individual Put difference it is a community that defines an individual This paper therefore is committed to review and critically examine contents in this Menkiti s radical communitarian position Doing this we shall examine the essence of a person individual with a special focus on metaphysical epistemic and moral constituents of a person the process of incorporation in traditional African society and the idea of depersonalization This paper assumes that Menkiti s failed to acknowledge the roles of an infant and the dead ancestors in the organization and development of a communit
