This study links police records, vital statistics, census data, and an original survey of 8,872 Chicago residents to assess an integrated theoretical perspective on neighborhood-level variations in homicide. We highlight two neglected dimensions of neighborhood context – social processes and spatial interdependence. Structural characteristics in 1990 and survey measures from 1995 are used to mo...

E-cadherin-mediated cell-cell adhesion is fundamental for epithelial tissue morphogenesis, physiology and repair. E-cadherin is a core transmembrane constituent of the zonula adherens (ZA), a belt-like adherens junction located at the apicolateral border in epithelial cells. The anchorage of ZA components to cortical actin filaments strengthens cell-cell cohesion and allows for junction contrac...

Background: Social capital has been defined as norms, networks, and social links that facilitate collective actions. Social capital is related to a number of main social and public health variables. Therefore, the present study aimed to determine the factors associated with social capital among the residents of Tehran, Iran.   Methods: In this large cross-sectional population-based stud...

Module cohesion describes the degree to which di erent actions performed by a module contribute towards a uni ed function. High module cohesion is a desirable property of a program. The program modi cations during successive maintenance interventions can have negative e ect on the structure of the program resulting in less cohesive modules. Therefore, metrics that measure module cohesion are im...

Class cohesion is considered as one of the most important object-oriented software attributes. High cohesion is, in fact, a desirable property of software. Many different metrics have been suggested in the last several years to measure the cohesion of classes in object-oriented systems. The class of structural object-oriented cohesion metrics is the most investigated category of cohesion metric...

Several models of flocking have been promoted based on simulations with qualitatively naturalistic behavior. In this paper we provide the first direct application of computational modeling methods to infer flocking behavior from experimental field data. We show that this approach is able to infer general rules for interaction, or lack of interaction, among members of a flock or, more generally,...

Human interaction through music is a vital part of social life across cultures. Influential accounts of the evolutionary origins of music favor cooperative functions related to social cohesion or competitive functions linked to sexual selection. However, work on non-human "chorusing" displays, as produced by congregations of male insects and frogs to attract female mates, suggests that cooperat...

Concepts and research from community psychology can inform community development practice by reframing social capital theory. Social capital (SC) is generally defined and measured at the interpersonal, community, institutional, or societal levels in terms of networks (bridging) and norms of reciprocity and trust (bonding) within those networks. SC should be analyzed in a multi-level ecological ...

The work presented in this paper has been carried out in the context of a summary writing environment provided with automatic grading. Regarding summarisation discourse, some of the most relevant variables identified in previous work are comprehension, adequacy, use of language, coherence, and cohesion. This work is focused on cohesion. The described exploratory study starts from basic automati...

study of collective actions is related to some of the most important issues in contemporary sociology such as cooperation, collective decision making, emergence of social norms etc. this paper in four steps presents a framework for studying collective actions. these steps are related to characteristics of collective actions (cooperation and common good), factors effecting the emergence of colle...
