Selected AbstractsSocial work in Israel: professional characteristics in an international comparative perspectiveINTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 4 2004Idit Weiss This article employs a comparative framework in the analysis of the professional characteristics of social work in Israel. Using the attributes and the power approaches to professions, Israeli social work is analysed according to eight variables: a protected ,trademark', monopoly over social care and delivery of services within state welfare systems, occupational autonomy, length of training and control over training, internal differentiation by levels of expertise and competence, professional organisation, a sanction-backed code of ethics, and material and symbolic rewards. The analysis reveals that Israeli social work has undergone an extensive professionalisation process and that it has characteristics that are not common in other countries. Initial explanations for this process are offered and discussed. [source] Space, Boundaries, and the Problem of Order: A View from Systems TheoryINTERNATIONAL POLITICAL SOCIOLOGY, Issue 3 2007Jan Helmig The idea our global polity is chiefly divided by territorially organized nation-states captures contemporary constellations of power and authority only insufficiently. Through a decoupling of power and the state, political spaces no longer match geographical spaces. Instead of simply acknowledging a challenge to the state, there is the need to rethink the changing meaning of space for political processes. The paper identifies three aspects, a reconceptualization of the spatial assumptions that IR needs to address: the production of space, the constitutive role of boundaries, and the problem of order. With this contribution, we argue that one avenue in understanding the production of space and the following questions of order is by converging systems theory and critical geopolitics. While the latter has already developed a conceptual apparatus to analyze the production of space, the former comes with an encompassing theoretical background, which takes "world society" as the starting point of analysis. In this respect, nation states are understood as a form of internal differentiation of a wider system, namely world society. [source] Ethnicity and Evolution of the Biodemographic Structure of Arbëreshe and Italian Populations of the Pollino Area, southern Italy (1820,1984)AMERICAN ANTHROPOLOGIST, Issue 4 2007Article first published online: 7 MAY 200 In the present study, we show how, through time, an ethnic mosaic and a changing social and economic context translated into intrapopulation differentiation and a change in genetic barriers between populations. Surname analysis was applied to a sample drawn from two centuries of marriage records in ten Arbëreshe and nine Italian villages of southern Italy to evaluate the evolution of internal differentiation and changes in genetic relationships between populations. Marital Isonymy and subdivision into subpopulations was higher in the Arbëreshe. Genetic barriers coinciding with ethnic boundaries characterized the 1800s. In the second half of the 1900s, ethnic differentiation disappeared. We hypothesize that socioeconomic changes, such as increased outmigration and regional mobility, were the forces that progressively eliminated the ethnic-related genetic differentiation in the region. This study has important implications for an understanding of the relationship between genetic evolution and the cultural milieu involving enforcement of ethnic differences. [source] The Walls Came Tumbling Up: The Production of Culture, Class and Native American SocietiesTHE AUSTRALIAN JOURNAL OF ANTHROPOLOGY, Issue 3 2006Gerald Sider In this paper, two historical moments in the continual formation of Native American societies are examined: the creation of distinct and bounded ,Indian' societies in the south-eastern colonial United States, and the recent internal differentiation of the Lumbee Indian peoples in North Carolina. Four issues are at stake: the production of difference and inequality within and between Native American societies; the formation and transformation of ,culture' in this context; a re-examination of the concept of class; and the simultaneous production of culture and class among indigenous peoples and perhaps more generally. This leads to a suggestion concerning the problem of hegemony in struggles over inequality. [source] Patterns of Floristic Differentiation among Atlantic Forests in Southeastern Brazil and the Influence of Climate,BIOTROPICA, Issue 4b 2000Ary T. Oliveira-Filho ABSTRACT The tree flora of southeastern Brazilian Atlantic forests was investigated according to two main aspects: (a) the variations in floristic composition of bodi rain and semi-deciduous forests were analyzed in terms of geographic and climatic variables by performing multivariate analyses on 125 existing floristic checklists; and (b) the links of both rain and semi-deciduous forests to Amazonian forests and Cerrados (woody savanna) were assessed. All analyses were performed at the species, genus, and family levels. The information obtained for the 125 forest areas was organized into an environmental database containing geographic and climatic records, and a floristic database containing binary presence records for 2532 species, 520 genera, and 106 families. Canonical correspondence analyses (CCA) were utilized to assess the relationship between geographic and climatic variables, and tree flora composition. Venn diagrams and cluster analyses were used to assess the floristic links to Amazonian forests and Cerrados. The following patterns were detected at all three taxonomic levels: (a) the differentiation between rain and semi-deciduous forests is floristically consistent and strongly correlated with rainfall regime, although transitions may be abrupt to gradual; (b) a north,south differentiation exists for both rain and semi-deciduous forests, probably caused by variations in both temperature and rainfall regime; (c) The flora of semi-deciduous forests also changes with increasing distance from the ocean and the associated increasing rainfall seasonality; and (d) elevation and associated temperatures are strongly correlated with the internal differentiation of both rain and semi-deciduous forests. To a considerable extent, the tree flora of semi-deciduous forests is a subset of the rain forest flora, probably extracting species that are able to cope with a longer dry season. There is greater floristic similarity at the species level between Atlantic rain and semi-deciduous forests than between any of these and either Amazonian rain forests or Cerrados. Nevertheless, semi-deciduous forests and Cerrados show stronger links, particularly at the generic and familial levels. Therefore, rhere is little floristic ground for viewing Atlantic rain forests as being closer to their Amazonian counterparts than to the adjacent semi-deciduous forests. The most appropriate view of rain and semi-deciduous forests in southeastern Brazil is that of a continuum in tree species distribution. We suggest that the definition of Atlantic forests should be as comprehensive as that of Amazonian forests. RESUMO A flora arbórea das florestas Atlãnticas do sudeste do Brasil é investigada sob dois aspectos principals: (a) as varia¸ões em composi¸ão florística de florestas ombrófilas e semidecíduas são analisadas sob a ótica de variáveis geográficas e climáticas por meio de análises multivariadas de 125 listagens florísticas existentes na literatura; e (b) os la¸os das florestas ombrófilas e semidecíduas com as florestas Amazõnicas e cerrados são avaliados. Todas análises foram feitas nos níveis de espécie, gênero e família. A informa¸ão obtida para as 125 áreas de floresta foi organizada em um banco de dados ambientais, contendo registros geográficos e climáticos, e um banco de dados florísticos, contendo registros binários de presen¸a para 2532 espécies, 520 gêneros e 106 famílias. Análises de correspondência canõnica (ACC) foram utilizadas para avaliar as rela¸ões entre variáveis geográficas e climáticas e a composi¸ão da flora arbórea. Diagramas de Venn e análises de agrupamento foram utilizados para avaliar os la¸os florísticos com florestas Amazõnicas e cerrados. Os seguintes padrões foram detectados para todos os níveis taxonõmicos: (a) A diferencia¸ão entre florestas ombrófilas e semidecíduas é floristicamente consistente e fortemente correlacionada com o regime de chuvas, embora as transi¸ões possam ser abruptas a graduais; (b) Há uma diferencia¸ão norte-sul tanto para florestas ombrófilas como semidecíduas, provavelmente causada por varia¸ões em temperatura e regime de chuvas; (c) A flora das florestas semidecíduas também muda com a distãncia do oceano e o correspondente aumento da dura¸ão da esta¸ão seca; e (d) Altitude e suas correspondentes varia¸ões de temperatura são fortemente correlacionadas com a diferencia¸ão interna tanto das florestas ombrófilas como semidecíduas. A flora arbórea das florestas semidecíduas é, em boa medida, um sub-conjunto da flora das florestas ombrófilas, provavelmente extraindo espécies capazes de enfrentar uma esta¸ão seca mais prolongada. Há mais similaridade florística, no nível de espécies, entre florestas Atlãnticas ombrófilas e semidecíduas do que entre qualquer destas e as florestas Amazõnicas, ou mesmo os cerrados. No entanto, florestas semidecíduas e cerrados mostram la¸os florísticos mais fortes, particularmente nos níveis de gênero e família. Portanto, há pouco fundamento florístico para se pensar nas florestas ombrófilas Atlãnticas como mais próximas de suas correspondentes Amazõnicas do que de suas vizinhas semidecíduas. A abordagem mais correta para florestas ombrófilas e semidecíduas do sudeste brasileiro é de um contínue de distribui¸ão de espécies. Sugerimos, portanto, que a defini¸ão de florestas Atlãnticas deve ser tão abrangente quanto a das florestas Amazõnicas. [source] |
