A self-discovery hypothesis regarding changing family dysfunctioning is suggested. From this hypothesis a method for treatment called Graphic Family Therapy has been developed. The four stages of this design—Analysis, Motivation, Evaluation and Research—are discussed. Specific graphic exercises for eight categories of family dysfunction are described. Two illustrative cases, one long-term and one short-term, are presented. Conclusions regarding results, future research, training and other clinical applications are offered.  相似文献

Given an undirected, connected graph G with maximum degree Δ, we introduce the concept of a [1, Δ]-factor k-packing in G, defined as a set of k edge-disjoint subgraphs of G such that every vertex of G has an incident edge in at least one subgraph. The problem of deciding whether a graph admits a [1,Δ]-factor k-packing is shown to be solvable in linear time for k = 2, but NP-complete for all k≥ 3. For k = 2, the optimisation problem of minimising the total number of edges of the subgraphs of the packing is NP-hard even when restricted to subcubic planar graphs, but can in general be approximated within a factor of by reduction to the Maximum 2-Edge-Colorable Subgraph problem. Finally, we discuss implications of the obtained results for the problem of fault-tolerant guarding of a grid, which provides the main motivation for research.  相似文献

Do standard “trust in government” survey questions deliver measures which are reliable and equivalent in meaning across diverse regime types? I test for the measurement equivalence of political trust in a sample of 35 former Soviet and European countries using the 2010 Life in Transition Survey II conducted by the World Bank and European Bank for Reconstruction and Development. Employing multiple group confirmatory factor analysis, I find that trust perceptions in central political institutions differ from (1) trust in regional and local political institutions, (2) trust in protective institutions like the armed forces and police and (3) trust in order institutions like the courts and police. Four measurement models achieve partial metric invariance and two reach partial scalar invariance in most countries, allowing for comparisons of correlates using latent factors from each model. I also found some clustering of measurement error and variation in the dimensionality of political trust between democratic and autocratic portions of the sample. On some measurement parameters, therefore, respondents in diverse cultures and regime types do not have equivalent understandings of political trust. The findings offer both optimism and a note of caution for researchers using political trust measures in cross-regime contexts.  相似文献

There is a need to study the effects of urbanization on wildlife in order to understand the ecological implications of increasing urbanization and find out how to reduce its threats to biodiversity. The blue tit evolved as a forest species and prefers deciduous and mixed forests, whereas its nesting in urban habitats is a more recent phenomenon. Our long-term study of blue tit populations has been conducted in two habitats: an urban parkland (frequently visited by people) and a deciduous forest outside of the city. Using linear mixed modeling, we revealed that a relationship of blue tit breeding success (and the number of fledglings) with thermal conditions in May differed between the urban parkland and the forest. While the relationship was positive in the forest, it was negative in the parkland. In addition, breeding success in the parkland increased with increasing number of rainy days in May. We argue that the main possible reason for such patterns is human activity in the parkland, which interferes with tit parental care, especially the regular feeding of nestlings, whereas it is evidently associated with weather conditions. Human disturbance in the forest is likely to be negligible.  相似文献

The threat that domestic cats pose to wildlife has gained increased recognition by researchers and conservationists, and in this study, we investigated the seasonal variability and the effects of environment type (rural vs. urban) on the prey composition of free-ranging house cats in Poland. We analysed the variability in 307 monthly prey samples of different prey items killed by cats and brought to their owners (i.e., prey brought home by cats living in one home in one month) between 2002 and 2007 at 26 rural and urban sites. The variability in prey composition over time was analysed using additive models and canonical correspondence analysis. In total, we recorded 1348 prey items. Rodents were the most common prey in both environments, but shrews and reptiles were killed by cats more often in the rural environment while birds (mainly sparrows and pigeons) were more common in the urban environment. Additionally, prey composition changed seasonally. The pooled number of vertebrates killed by cats was largest in September and lowest in January, and rodents were killed most often in September, shrews and birds in June, and reptiles in April. The seasonal variation in the prey composition of cats was relatively high in the rural environment and more stable in the urban environment. Prey composition seemed to follow temporal and spatial variations in prey availability, thus confirming a facultative feeding strategy in free-ranging house cats.  相似文献

This article is an analysis of the relationship between, on the one hand, empirical findings and theoretical perspectives on the sexualization of the workplace and, on the other, changes in public policy intended to prevent and eliminate sexual harassment as a problem for employed women. The sexualization on the workplace is conceptualized as all consensual and coerced sexual interactions at work, that is, both sexual harassment and sexual relationships. A summary of the evidence regarding both types of behaviors reveals that sexual harassment is experienced quite often by women workers; occasionally, women engage in sexual relationships with persons met at work. Harassment has significant negative consequences for the economic, emotional and physical condition of women, delimiting further an economic position for women which has already been affected severely by occupational segregation and employment discrimination. In assessing the impact of guidelines of the Equal Employment Opportunity Commission defining sexual harassment as sexual discrimination, issues are raised concerning the use and effectiveness of the guidelines by women workers, courts, and employers. It is argued that public policy on harassment is necessary and progressive but limited in its impact; the bulk of the problem, especially with regard to co-worker behavior, and the structural context of inequality are left relatively untouched.This article is a revision of a presentation given at the Labor Studies Colloquium, the Society for the Study of Social Problems (August 1984).  相似文献

This paper focuses on the latent, underlying hostility that we feel exists between adoptive parents and their adopted children. The focus of this study is on the adolescent adoptee who is struggling with a “double” identity-crisis. Also addressed are countertransference feelings between the adoptive parent and the adolescent adoptee.  相似文献

Despite laws in the United States enacted to protect individuals with disabilities in prison, there is ample case law to demonstrate that the intent of these laws has not been achieved. Using the existing US legal and social science literatures and experiences, this article considers: the problems hearing-impaired offenders face in prison that are not encountered by non-deaf or hard of hearing inmates; the services and accommodations prisons provide for deaf or hard of hearing inmates so that they can function at least as well as non-deaf or hard of hearing inmates; and the types of scientific research that should be conducted to understand the possible types of deaf or hard of hearing experiences in prisons, the consequences of these experiences, and the best way to address pathological sequela of being deaf or hard of hearing in prison. We argue that the creation of rules to protect this population is of no value unless these laws are implemented as intended. Without monitoring the law in action and studying why the intent of the law may be thwarted, an atmosphere in which deaf or hard of hearing offenders are neglected and even abused will likely occur.  相似文献
