The Internet opens a vast array of communication, entertainment, and educational resources for children; however, it also opens a gateway to home and school for offenders who wish to exploit children. A convenience sample of 225 cases published in the news media was examined. The cases were classified using law enforcement terminology to describe Internet offenders as traders, travelers, or combination trader-travelers. The media is seen as a critical source of information for the public to be aware of how the Internet is being used to commit sexual exploitation and sex crimes against children.  相似文献

The green revolution was a planned intervention expected to raise cereal-grain production in Third World countries. Use of high yield varieties (HYVs) was to reduce dependence on food imports and bring about food self-sufficiency. Early results were increased overall cereal-grain production, but unforseen and undesirable social and economic consequences. The use of organizational development (OD) analysis of early green revolution results indicates that the initial strategy relied on a “hard” systems analysis to bring about adoption of the high yield varieties. Early green revolution work attempted to induce attitude and behaviour change within existing local and regional institutions. Recognizing the need to ensure distribution of green revolution inputs among subsistence farmers, later strategies used a “soft” systems analysis in developing structural intervention. Largely unable to reform existing government institutions and land-holding patterns which restricted small farmer HYV programme participation, programme managers designed alternative structures to allow the small/subsistence farmer access to HYV inputs.  相似文献

The Age Discrimination in Employment Act (ADEA) was amended in 1978 to prohibit mandatory retirement before age 70 in most occupations. The impact of this legislation on the probability of older persons remaining in the labor force is the primary concern of this article. Specifically, questions concerning which older workers are affected by mandatory-retirement provisions and the extent to which they are forced to retire and leave the labor force are examined. Tabular analysis of data from the Retirement History Study on persons aged 62-63 in 1969 shows significant variation in mandatory-retirement coverage between the public and private sectors and across industries, occupations, and demographic groups. Until age 65, the labor-force participation rate of those facing compulsory retirement is higher than or equal to that of those not covered but it drops significantly below the noncovered rate after 65. Logit analysis of the labor-force participation of persons before and after age 65 indicates that mandatory retirement at that age reduces the probability of retirement by approximately 16.7 percentage points for white men wage earners. This results in a decline in the labor-force participation rate of all men aged 66-67 of approximately 4 percentage points.  相似文献

Neurocysticercosis results when the ingested eggs of the pork tapeworm, Taenia solium, hatch into larval forms that penetrate the gut wall, disseminate hematogenously, and then encyst in the brain. The subsequent symptoms and associated morbidity are variable. Worldwide, cysticercosis is the most common parasitic disease affecting the central nervous system, but it is not a common autopsy finding in the United States. Neurocysticercosis may be an incidental finding, a contributing cause of death, or the underlying cause of death. It is also important for the forensic pathologist to be aware of the possibility of neurocysticercosis in the autopsy population for purposes of epidemiology studies and infection control. The authors use cases of neurocysticercosis found at autopsy at their institution to give examples of each scenario and to review the clinical and pathologic features of this parasitic disease.  相似文献

Correlations between adolescent and parent reports of adolescent problems are low in magnitude. In community samples adolescents tend to report more problems than parents and in clinical samples adolescents tend to report fewer problems than parents. Indices of agreement may be biased if some adolescents in a given sample report more problems and others report fewer problems than parents. In the current study, order and mean agreement between adolescent and maternal reports of adolescent internalizing and externalizing problems, taking into account the direction of disagreement, was examined in a community sample of 133 young adolescents and their mothers. Two-thirds to three-quarters of adolescents reported more problems than mothers. Accounting for the direction of discrepancies resulted in improved agreement between adolescents and mothers and differing patterns of predictors of discrepancies. Additionally, the results demonstrate the need to control for relations between adolescent-reported problems and discrepancies when exploring predictors of discrepancies. Erin T.

Questionnaire data were obtained from 120 high school students on their (1) knowledge of risk factors that identify potential suicidal behavior in peers, (2) attitudes toward peers who attempt or commit suicide, and (3) ability to respond appropriately to suicidal messages from peers. Overall, relatively few adolescents possessed accurate information, and many had misinformation concerning various warning signs. Furthermore, respondents expressed negative attitudes toward peers who attempt or commit suicide, and generally were unable to respond sensitively and appropriately to suicidal communications. These results have implications for suicide education programs for adolescents.This study was based on a Masters Thesis conducted by the first author under the direction of the latter two authors. Preliminary results of this investigation were presented at the Midwestern Psychological Association, Chicago, 1988.Received M.A. in clinical psychology from Loyola University.

Various theories, theoretical viewpoints and models on consumer behaviour stipulate consumers’ offline and online behaviour when purchasing a product or using a service. This article deviates from the purchasing perspective and instead proposes an information and web-based communication message ‘seeking and consumption1 perspective. This new perspective is theoretically grounded in two new approaches to online consumer behaviour: the web-based communication exposure and internal psychological behavioural processes approaches; as well as the integration of various theoretical perspectives, approaches, theories and models that address fragments of offline and online consumer behaviour. The research problem is to address the existing limited and fragmented approaches, because existing purchasing perspectives arguably do not provide adequate theoretical criteria to explain online consumer behaviour during interactive information-seeking and consumption activities. Hence, the main aim of this article is to propose new theoretical criteria for online consumer behaviour to address these shortcomings.  相似文献
