Rates of reported child maltreatment nearly doubled in Canada over the period 1998–2003, an increase that reflects growing awareness of the harmful effects of an expanding array of parental behaviors, including corporal punishment, lack of supervision, and exposure to intimate partner violence (IPV). Some of these situations may benefit from voluntary family support programs outside of the child welfare system. Analyzing a sample of 11,807 investigations, this paper compares cases where the sole concern is exposure to IPV, or hitting a child, or neglect, or other forms of investigated maltreatment. Situations where exposure to IPV or potentially abusive hitting were the sole reason for investigation presented with fewer risk factors and were less likely to lead to ongoing child welfare interventions compared to other maltreatment investigations. While situations involving alleged neglect presented a higher risk profile and elicited a more intensive child welfare response than did exposure to IPV or hitting, opportunities for alternative services were nevertheless identified. The study also found that visible minority families were overrepresented in cases involving hitting and that Aboriginal families were overrepresented in cases involving neglect. Overall the findings support the development of alternative response programs in Canada.  相似文献

Our subjective experience of the world as being in full colour across the entire visual field is at odds with the highly fovea-biased distribution of cones in the retina. It is unclear how this percept of “pan-field colour” comes about. We use novel stimuli—“colour chimeras”—to demonstrate a related visual phenomenon in which observers perceive rich colour throughout images with large achromatic regions. This percept appears to critically depend on natural scene statistics. By separately manipulating chromatic and structural content in such images, we demonstrate that both the spatial distribution of colour and the presence of recognizable scene structure contribute to the experience of pan-field colour in these stimuli. Our results suggest that this percept is unlikely to be due to a low-level colour spreading process. Instead, we suggest that mechanisms dependent on natural scenes’ chromatic and luminance statistics provide the basis for the phenomenon.  相似文献

Learning to recognize objects appears to depend critically on extended observation of appearance over time. Specifically, temporal association between dissimilar views of an object has been proposed as a tool for learning invariant representations for recognition. We examined heretofore untested aspects of the temporal association hypothesis using a familiar dynamic object, the human body. Specifically, we examined the role of appearance prediction (temporal asymmetry) in temporal association. In our task, observers performed a change detection task using upright and inverted images of a walking body either with or without previous exposure to a motion stimulus depicting an upright walker. Observers who were exposed to the dynamic stimulus were further divided into two groups dependent on whether the observed motion depicted forward or backward walking. We find that the effect of the motion stimulus on sensitivity is highly dependent on whether the observed motion is consistent with past experience.  相似文献

The transplant of the western form of industrial organizations in India was expected to bring a radical shift from a dependency and personalized to a contractual work relationship, from a steeply hierarchical to a reasonably egalitarian authority structure, ascribed to occupational bases of identity formation. The shift did not occur to the extent it was expected. Instead, technological requirements and job demands at many places were unduly compromised with the socio-cultural factors leading to soft management style which proved to be dysfunctional. At other places, the same socio-cultural factors helped develop a synergetic work culture where workers and managers worked together for higher productivity and greater viability. The critical factor which made the difference was the establishment of work as the master value. The other social values played a facilitating role in establishing and realizing the work values.  相似文献

The predictive value of the ecocultural model in the development of cognitive style was examined among the two cultural groups of Gurungs and Brahmins residing in contrasting ecologies of the hills and plains of Nepal. Acculturative influence of formal schooling was also analyzed. Story–Pictorial EFT (S–P EFT) for measuring cognitive style was administered to 240 children of 6–8 years divided into eight equal sub-groups according to two types of ecologies, two cultures and two levels of education. A 2 × 2 × 2 ANOVA revealed significant main effects of ecology and schooling. Effect of culture was not significant, but it played a significant role in conjunction with ecology. Findings are discussed in the light of relative functional utility of disembedding/analytical skill for the inhabitants of hills and plains.  相似文献

The study was an investigation of the effects of density and personal space on simple and complex task performance and on feelings of crowding on 60 female Hindu students in India. A 2 x 2 design was used. Density was manipulated by varying the number of subjects in a fixed room space (social density), and the stop-distance technique was used to measure personal space. Results revealed that complex task performance was adversely affected by a high-density condition and by the personal space of the subjects, leading to a significant interaction effect of the two variables, but no significant main or interaction effect was found for the simple task performance. The subjects with "far" personal space under the high-density condition evaluated the environment of the experimental room as most crowded, more than any other subject did.  相似文献

Over twenty years back, the concept of development and the resource superiority in the West imposed on the Third World psychologists a relationship which since then has evolved from the stage of pure subordination through indigenization into a phase which might turn out to be relatively more collaborative. The purpose of this paper is to take a brief historical account of the process of this evolving relationship which also tends to change the concept of development itself. The purely economic concept of development through industrialization and individual efforts has yielded to an emerging view of development where economic, social, environmental, and other factors are integrated and centred around human development. While based primarily on the Indian experiences, the perspective developed here may have some relevance to the Third World in general.  相似文献
