از خانه های گرید با ابعاد 10 * 10 کیلومتر و روش محدوده های دایره ای همسایه (circular neighborhood method) با شعاع 50 کیلومتر برای نقشه برداری غنای گونه ای استفاده شد. غنای گونه ای بالایی در البرز مرکزی و در استان لرستان و فارس دیده شد. در طول جغرافیایی 35/51 درجه بیشترین غنای گونه ای بین عرض جغرافیایی 29/31 درجه شمالی و 36و 37 درجه شمالی قرار دارد. یک نقطه داغ بومزادی در ناحیه البرز مرکزی برای ...
BACKGROUND We sought to examine whether neighborhood deprivation is associated with participation in a large population-based health check. Such analyses will help answer the question whether health checks, which are designed to meet the needs of residents in deprived neighborhoods, may increase participation and prove to be more effective in preventing disease. In Europe, no study has previous...
This study examines how the neighborhood environments experienced over multiple generations of a family influence children’s cognitive ability. Building on recent research showing strong continuity in neighborhood environments across generations of family members, we argue for a revised perspective on “neighborhood effects” that considers the ways in which the neighborhood environment in one ge...
today, the women from the half of the civil society population and from the perspective of security in the urban society, they are vulnerable social groups that their security is threatened in different ways. this study seeks to examine the factors affecting social security of women living in two neighborhoods in vanak and sarasiab. research theoretical model is composed (inspired by the views ...
attachment to the neighborhood represents a positive mental feeling toward the residential place that links associated with residential location and causing the residents’ commitment to habitat and their desire to maintain a relationship with it over the time and at different stages of life. present research examines neighborhood attachment and the effect of personal networks and modern communi...
The wormhole attack is a severe threat to wireless sensor networks. Most existing countermeasures for detecting and locating wormhole links either require extra hardware or are too complex for the inherently capability-constrained sensor nodes. Actually, wormhole links can enormously change the original sensor network topology. In this paper, we introduce the HCA4DW mechanism for detecting and ...
The purpose of this study was to test direct, additive, and mediation models involving family, neighborhood, and peer factors in relation to emerging antisocial behavior and social skills. Neighborhood danger, maternal depressive symptoms, and supportive parenting were assessed in early childhood. Peer group acceptance was measured in middle childhood, and data on antisocial behavior and social...
Qualitative representations of spatial knowledge aim to capture the essential properties and relations of the underlying spatial domain. In addition, conceptual neighborhood has been introduced to describe how qualitative spatial relations may change over time. Current qualitative representations mainly use symbolic constraint-based languages that are detached from the underlying domain with th...
Two algorithms for the efficient identification of segment neighborhoods are presented. A segment neighborhood is a set of contiguous residues that share common features. Two procedures are developed to efficiently find estimates for the parameters of the model that describe these features and for the residues that define the boundaries of each segment neighborhood. The algorithms can accept ne...
Obesity is more prevalent and its consequences severe among middle-aged and older adults. Efforts to understand and address neighborhood-level causes of obesity in this population offer the potential to enhance health and reduce the costs of obesity for everyone. The accompanying paper by Li et al. (Am J Epidemiol. 2009;169(4):401-408) presents new data on the apparently significant interaction...
