Local community detection algorithms are an important type of overlapping community detection methods. Local community detection methods identify local community structure through searching seeds and expansion process. In this paper, we propose a novel local community detection method on line graph through degree centrality and expansion (LCDDCE). We firstly employ line graph model to transfer edges into nodes of a new graph. Secondly, we evaluate edges relationship through a novel node similarity method on line graph. Thirdly, we introduce local community detection framework to identify local node community structure of line graph, combined with degree centrality and PageRank algorithm. Finally, we transfer them back into original graph. The experimental results on three classical benchmarks show that our LCDDCE method achieves a higher performance on normalized mutual information metric with other typical methods.

Values associated with statewide freight and tourist mobility; traffic, pedestrian, and bicycle safety; and small-town livability create competing objectives that are difficult to balance when main streets of small towns are also state highways. Many communities opt for bypass solutions to these issues, but the Philomath Couplet Project represents a main street solution that is sensitive to both the demands of the state highway system and the character of the local community. The controversial 10-month decision process culminated in the selection of a preferred alternative. Final design is under way, and construction is scheduled for 2006. Although many projects are developed according to context-sensitive solution principles, the Philomath Couplet Project represents a class of projects with characteristics likely to be faced throughout the United States in relation to the management of state highways that are also main streets of small towns. The difficulties encountered in conducting this project provide important insights to guide context-sensitive solutions implementation in these circumstances. The lessons learned shared in this paper highlight the need to manage the “end game” of small-town politics, the value of time and cost constraints, the need for a structured decision process, and the usefulness of evaluation criteria based on interactions of land use and transportation.

The Impact

This chapter examines the ecological and evolutionary dynamics of species across a metacommunity, and how these dynamics affect regional community structure. It begins with a discussion of the evolution of dispersal, focusing on when movement between local communities is and is not favored by natural selection, and how these various movement patterns shape local community structure. An example of the demographic consequences of dispersal is presented, and the evolution of dispersal in a temporally constant environment is analyzed. The chapter also considers the evolution of dispersal rates among communities along with local adaptation within each and explains how link species affect local abundances via their movement strategies. Finally, it explores the interplay between local adaptation and dispersal evolution, the impact of simultaneous spatial and temporal variation in environmental conditions on the evolution of dispersal among populations, and the evolution of phenotypic plasticity.

Regional Community

This book investigates how local and regional patterns of community structure develop across space and through time by focusing on the theoretical interrelationships among community ecology, evolutionary adaptation, dispersal, and speciation and extinction. It discusses the purely ecological dynamics of interacting species in different community modules, how species in simple community modules evolve to adapt to one another, and how speciation and biogeographic mixing of taxa influence local community structure. It also examines community mixing due to climate change and how regional community structure is shaped by the ecological and evolutionary dynamics of species across a metacommunity. This introduction provides an overview of the evolutionary trajectories of various species in the context of ecological opportunity and community ecology, aggregated taxa in the trophic web, types of species found in a community, sources of biodiversity in a community, and the dynamics of natural selection, coevolution, and community structure.

Abstract By analyzing a Taiwanese anti-pollution movement, this paper tries to shed light on the elements of folk religion in collective action. The Houchin protest took place in 1987 when local people opposed to the further expansion of the China Petroleum Company (CPC). This case is an important milestone in the history of Taiwanese environmentalism and famous for its persistent protest over three years. In order to see how a local community sustains its solidarity through localistic folk religion, it is worth taking a close look at the community structure prior to the protest mobilization. The next section discusses Houchin people's reaction to the CPC's upgrading plan. Here the anti-pollution protest is viewed as an emergency occasion to revive the communal solidarity. Religion permeates the whole process of their collective action by supplying ritualized forms of contention. Religion in action is more than an instrument for mobilization, but rather substantially affects the movement goal and meaning for the participants. These highly localistic messages often escape outsiders' observation. In conclusion, the paper discusses the discovery in the light of study on Taiwanese environmental movement.

<p>ABSTRACT<br />The surge in malnutrition prevalence of underweight children under five from 17.9% to 19.6% in the 2007-2013 period, indicates that Indonesia is facing problems in terms of public health. Previous studies showed that the nutritional status and the health of children are concerned with the social practices of their food choices. The purpose of this study is to identify the forms of social structure and analyze the structures that play a role as inhibitors or activators social practices of food choice for children. This study involved 200 people of the main organizer of family food from the two communities in West Java province. Communities chosen have characterized the local community of highland and lowland agriculture. The results show that the structures that play a role as inhibitors or activators social practices of food choice in the highland community are the selection of food supplied from outside the community (structure of domination), income (structure of domination), and access to means of transportation (structure of domination). Meanwhile , at the community of lowland , structural inhibitors and activators social practices of food choice were identified as the food regulation for children who suffer from pain (structure of legitimacy), norms of parenting (structure of legitimacy ), a selection of food supplied from outside the community (structure of domination) and family support (structure of domination).<br />Keywords: social practices, food choices, structure</p><p>ABSTRAK<br />Melonjaknya prevalensi gizi underweight anak balita dari 17.9% menjadi 19.6% pada tahun 2007-2013 menandai Indonesia sedang menghadapi masalah dalam hal kesehatan masyarakat. Penelitian-penelitian sebelumnya menunjukkan bahwa status gizi dan kesehatan anak mempunyai kaitan dengan praktik sosial pilihan pangan. Tujuan penelitian ini adalah mengidentifikasi bentuk struktur sosial dan menganalisis struktur sosial yang berperan menghambat dan mengaktifkan praktik sosial pilihan pangan untuk anak. Kajian ini melibatkan 200 individu pengelola utama pangan keluarga dari dua komunitas di propinsi Jawa Barat. Komunitas yang dipilih mencirikan komunitas lokal pertanian dataran tinggi dan komunitas lokal pertanian dataran rendah. Hasil penelitian menemukan bahwa struktur yang berperan sebagai penghambat atau pengaktif praktik sosial pilihan pangan pada komunitas dataran tinggi adalah pilihan pangan yang disediakan dari luar komunitas (struktur dominasi), biaya/penghasilan (sumberdaya alokatif-struktur dominasi), dan akses sarana transportasi (sumberdaya alokatif-struktur dominasi). Sementara itu, pada komunitas dataran rendah, struktur penghambat dan pengaktif praktik sosial pilihan pangan yang teridentifikasi adalah aturan pangan untuk anak yang menderita sakit (aturan-struktur legitimasi), norma pengasuhan anak (aturan-struktur legitimasi), pilihan pangan yang disediakan dari luar komunitas (struktur dominasi) dan dukungan keluarga (struktur dominasi).<br />Kata kunci: praktik sosial, pilihan pangan, struktur</p>
