Children who have been sexually abused by a ring of adults present in a way that may confuse and mislead practitioners familiar only with single-offender sexual abuse. Understanding the similarities and differences between single- and multiple-offender sexual abuse is essential in determining the validity of a child's disclosure as well as in carrying out an appropriate treatment plan. Addressing the denial and resistance within the child welfare system in relation to child sexual exploitation by a ring is crucial to a practitioner's effectiveness. Finally, developing a therapeutic parent-child relationship is critical to the families who must live with their child's experience. 相似文献

Abstract Maintaining a healthy balance between human prosperity and environmental integrity is at the core of the principles of Ecological Sustainable Development. Resource‐protection policies are frequently implemented so as to regulate the balance between resource access and use, however, they can inadvertently compromise the ability of resource users to adapt and be resilient. Resource users who are especially dependent on a resource are more seriously compromised. But how do we define and measure resource dependency? And how do we assess its ability to influence social resilience? In this study, a conceptual model of resource dependency is developed in terms of: (i) occupational attachment, (ii) attachment to place, (iii) employability, (iv) family attitude to change, (v) business size, (vi) business approach, (vii) financial situation, (viii) level of specialisation, (ix) time spent harvesting, and (x) interest in and knowledge of the environment. The model of resource dependency and its effect on social resilience are (quantitatively and qualitatively) tested and explored using the commercial fishing industry in North Queensland, Australia. Results show that occupational attachment and employability were important influences as were business size and approach. Results can be used to identify vulnerability to institutional change and guide policy development processes. 相似文献

Two studies of working families are combined to demonstrate a strategy for producing reliable estimates from the combination of self-reported (large N) and observational (small N) data. Both studies examine where and how dual-career families spend time at home. The 500 Family Study is sociological and uses self-reported time diary data from a national sample; the CELF study is anthropological and uses observational scan sampling data from a regional sample of 32 families. The data are combined as if they constitute one sample, and an analytic solution for establishing the reliability of the resulting composite estimates of time use is provided. Merging the data sets provides validation for each study, neither of which is without potential methodological weaknesses. The advantages of combining data from the independent data collection methods are discussed, and selected substantive findings on families' activities are highlighted, illustrating similarities and differences between findings in the independent and combined data sets. Results show that working families spend significant time in a small spectrum of home spaces, particularly kitchens and living rooms, with leisure activities prevailing, but mothers, fathers, and children differ in where and how they spend their time. Overall, a template for merging data from different disciplines and methods is provided. 相似文献

This article uses archival evidence to study in depth the historical policies of Italy as a classic sending state. Most of the mass migrations of a century ago came from multinational empires, but Italy was a recently formed independent state. Ambitious to benefit from emigration while assisting and protecting emigrants, Italy reached out to “Italians abroad” in several ways. For example, the state opened a low‐cost channel for remittances through a nonprofit bank; promoted Italian language education among Italian families abroad; supported Italian Chambers of Commerce abroad; and subsidized religious missionary work among emigrants. Italy's historical example of political innovation and diplomatic negotiation provides context, comparisons, and possibilities for rapidly changing sending‐state policies in the twenty‐first century. 相似文献

In a survey of professors and lectureres at German and Swiss universities we asked for mathematical skills that are prerequisites for successful studies in the social sciences and in psychology. Basic contents of lower secondary education (Sekundarstufe I) were reported as most important. Nevertheless in a hypothetical preparatory mathematics class respondents would like an equal amount of stochastics to be included. Respondents differ especially with repect to their perceived importance of stochastics knowledge prior to immatriculation. While some respondents underline its outstanding importance others consider it completely unnecessary to have stochastic knowledge in advance. There is consent about the level of importance of all other disciplines, calculus and linear algebra being of medium importance, geometry and game theory being less important. Psychologists differ from social scientists in putting even less emphasis on calculus. Aside from differences with respect to stochastics the study indicates the existence of standard requirements shared by all professors and lectureres irrespective of their discipline. This finding facilitates construction of preparatory courses for students across subjects. 相似文献

In morphological image processing and analysis, a template or structuringelement is applied to an image. Often savings in computation time and abetter fit to the given computer architecture can be achieved by using thetechnique of template decomposition. Researchers have written a multitude ofpapers on finding such decompositions for special classes of templates.Justifying recent integer programming approaches to the morphologicaltemplate decomposition problem in its general form, this paper proves theNP-completeness of this problem. 相似文献

Principal component and correspondence analysis can both be used as exploratory methods for representing multivariate data in two dimensions. Circumstances under which the, possibly inappropriate, application of principal components to untransformed compositional data approximates to a correspondence analysis of the raw data are noted. Aitchison (1986) has proposed a method for the principal component analysis of compositional data involving transformation of the raw data. It is shown how this can be approximated by a correspondence analysis of appropriately transformed data. The latter approach may be preferable when there are zeroes in the data. 相似文献
