Throughout the world there is a growing understanding of information as a most important product of social production, as a constantly growing resource of mankind, as a most valuable and popular commodity in international trade. Information and propaganda based on it have become a powerful means that can be used to solve the most complex problems, including those that have more than once in history led to armed struggle. The tendency toward the increased role of information in the life of society is the basis for the conclusion that under the present conditions of historical competition the socioeconomic system that will win is the one that possesses the higher quality information, that assimilates it faster, in greater volume, and more efficiently for the attainment of mankind's common goals. 相似文献

This study analyzes three years of data on misdemeanor drug offenders in Winnebago County, Wisconsin. A portion of these offenders opted into a Misdemeanor Drug Diversion Program (MDDP) offered instead of traditional adjudication. Recidivism in the treatment and comparison groups is estimated using standard binary response techniques augmented with propensity score matching to address selection bias. Results show that the MDDP reduces the probability of re-offense by 16%, after adjusting for possible selection bias. Cox proportional hazard modeling is also used to assess time-to-re-offense differentials between the treatment and comparison groups. The survival analysis indicates that the hazard rate of re-offense is 60% lower per day among those treated with the MDDP program than those who did not complete the program. The average number of days to re-offense among those that do re-offend is 297 days in the treatment group and 203 days in the comparison group. 相似文献

In a longitudinal investigation of the antecedents and pathways of teen parenthood, 475 participants (248 females and 227 males) were followed from Grade 7 through early adulthood. In the first year of the investigation, homogeneous subgroups were identified by clustering participants on five characteristics (i.e., aggression, popularity, academic competence, age, and socioeconomic status). At the same time, peer social networks were identified by the Social Cognitive Map procedure. For each participant, the configuration of peer characteristics was also identified. A high correspondence was found between the individual characteristics and the characteristics of closely affiliated peers. Both teen fatherhood and teen motherhood were predicted by individual configurations and peer configurations (e.g., a combination of high aggression, low academic competence, low popularity, and low family SES). Peer characteristics, race, and family socioeconomic status assumed unique roles in predicting teen motherhood. Growth curve analyses showed that teen-mothers differed from non-mothers in their starting points and developmental trajectories. This study demonstrated that a simultaneous examination of both the individual and his/her peer context yielded important information on teen parenthood. 相似文献

The purpose of this study was to examine the validity of a new procedure for assessing infant-mother attachment. Sixty children (34 in child care) and their mothers were seen in the Strange Situation (SS) at 17 months and in a new attachment assessment, the California Attachment Procedure (CAP), which does not involve mother-child separations, at 18 months. Overall, children were more likely to be classified as secure in the CAP (83% vs. 67%), but this was particularly true for children with experience in routine nonmaternal care. Of the children in nonmaternal care who were insecure in the SS, 91% were secure in the CAP, whereas of the maternal-care children who were insecure in the SS, only 44% were secure in the CAP. Attachment security in the CAP was more highly correlated with observed maternal sensitivity than was attachment security in the SS, particularly for children in nonmaternal care. 相似文献

Use of a conceptual model of societal drivers of ecological change in South Florida: Implications of an ecosystem management scenario 总被引:3,自引:0,他引:3

Human-dominated ecosystems such as in South Florida's Everglades region are greatly affected by societal actions and choices, and efforts to restore degraded ecosystems must take into account the societal drivers of ecosystem change. A conceptual model of societal-ecological interactions within the region illustrates connections between major societal drivers, such as water management and land use, and ecological stressors, such as loss of habitat and nutrient loading. Using the conceptual model as an initial guide for discussion, examination of a restoration scenario for the region shows that social and economic effects from activities proposed in a restoration scenario will likely affect most sectors of South Florida. Political effects from changing land and water management practices likely will be significant, as will the physical effects of changing water structures and management practices. Conceptual models such as this can aid in the initial stages of ecosystem restoration discussions and can assist in planning for subsequent social science evaluations of specific societal impacts of actual proposed governmental restoration alternatives. In crafting restoration scenarios, local, regional, and national decision makers can use conceptual models such as this to help broaden the early considerations of how possible future changes in societal drivers, including management choices, will change ecological stressors that affect ecosystem health. 相似文献

The paper examines contemporary social movement activity within South West England. It is argued that much social movement analysis has been too nation‐state orientated, that it has too readily framed diverse contemporary practices within a narrow, politically reductive and instrumentally rational frame. Increasingly, aesthetic and affective dimensions of everyday life must be examined if any coherent theoretical account of such activity is to be offered. Altering relations between states and their citizens in a global age and the emergence of an extended civil society are linked to a weakening of the capacity of nation states to manage identity formation. A series of excursuses link theoretical analysis of the expressive dimensions of the region's social movement activity, to these more extended global transformations. 相似文献
