Contemporary Models of Youth Development and Problem Prevention: Toward an Integration of Terms, Concepts, and Models

FAMILY RELATIONS, Issue 1 2004
Stephen Small
Over the past several years, increased interest in preventing youth problems and promoting healthy youth development has led youth and family practitioners, policy makers, and researchers to develop a wide range of approaches based on various theoretical frameworks. Although the growth in guiding frameworks has led to more complex models and a greater diversity in the options available to scholars and practitioners, the lack of an integrative conceptual scheme and consistent terminology has led to some confusion in the field. Here, we provide an overview of three approaches to youth development and problem prevention, critically examine their strengths and weaknesses, and offer some elaborations to help clarify, extend, and integrate the models. We conclude by discussing some general implications for researchers, practitioners, and policy makers. [source]

Landscape modification and habitat fragmentation: a synthesis

GLOBAL ECOLOGY, Issue 3 2007
Joern Fischer
ABSTRACT Landscape modification and habitat fragmentation are key drivers of global species loss. Their effects may be understood by focusing on: (1) individual species and the processes threatening them, and (2) human-perceived landscape patterns and their correlation with species and assemblages. Individual species may decline as a result of interacting exogenous and endogenous threats, including habitat loss, habitat degradation, habitat isolation, changes in the biology, behaviour, and interactions of species, as well as additional, stochastic threats. Human-perceived landscape patterns that are frequently correlated with species assemblages include the amount and structure of native vegetation, the prevalence of anthropogenic edges, the degree of landscape connectivity, and the structure and heterogeneity of modified areas. Extinction cascades are particularly likely to occur in landscapes with low native vegetation cover, low landscape connectivity, degraded native vegetation and intensive land use in modified areas, especially if keystone species or entire functional groups of species are lost. This review (1) demonstrates that species-oriented and pattern-oriented approaches to understanding the ecology of modified landscapes are highly complementary, (2) clarifies the links between a wide range of interconnected themes, and (3) provides clear and consistent terminology. Tangible research and management priorities are outlined that are likely to benefit the conservation of native species in modified landscapes around the world. [source]

Towards a geography of transnational spaces: Indian transnational communities in Australia

GLOBAL NETWORKS, Issue 1 2004
Carmen Voigt-Graf
In this article, the geography of the transnational spaces of Punjabis, Kannadigas and Indo-Fijians is analysed. Punjabis have constructed complex transnational spaces that are virtually global in scale. Kannadigas are engaged in transnational activities linking their places of residence with south India. Indo-Fijians have emerged as a regional transnational community stretching across the Pacific Ocean. On the basis of their experiences, a consistent terminology is suggested and a typology of different models of transnational spaces is developed. This typology provides a tool to compare different transnational communities beyond the Indian experience. It can be seen as a preliminary step in the direction of a more theoretical approach that links the geography of migrant transnational spaces with sociological debates on social space. [source]

An Update on Data Standards for Gel Electrophoresis

PROTEINS: STRUCTURE, FUNCTION AND BIOINFORMATICS, Issue S1 2007
Andrew R Jones Dr.
The use of gel electrophoresis to separate and, in some instances, to quantify the abundance of large numbers of proteins from complex mixtures, has been well established for several decades. The quantity of publicly available data is still relatively modest due to a lack of community accepted data standards, tools to facilitate the data sharing process and controlled vocabularies to ensure that consistent terminology is used to describe the experimental methodology. It is becoming widely recognised that there are significant benefits in data sharing for proteomics, allowing results to be verified and new findings to be generated by re-analysis of published studies. We report on standards development by the Gel Analysis Workgroup of the Proteomics Standards Initiative. The workgroup develops reporting requirements, data formats and controlled vocabularies for experimental gel electrophoresis, and informatics performed on gel images. We present a tutorial on how such resources can be used and how the community should get involved with the on-going projects. Finally, we present a roadmap for future developments in this area.
