This article reports the first results of the three-year longitudinal study of the social maps of children beginning the transition to adolescence. This exploratory study is guided by Bronfenbrenner's conception of the ecology of human development, stressing the importance of a phenomenological orientation to development in the context of ecological transitions. The study focuses on characteristics of children's social networks (the web of relationships in which the individual is involved) as a function of neighborhood type, socioeconomic status, and level of physical maturation. The social heterogeneity of the social network (e.g., the relative salience of peers versus adults) is a primary concern. The child's and parent's perceptions of the network, of the people available to help the child, and the child's friends are compared within the context of ecological, socioeconomic, and maturational factors. The results (for 111 sixth-grade children from three contrasting neighborhood schools) shed some light on age segregation and the overall heterogeneity of the social environments of children facing the transition to adolescence. They provide a context and a baseline for the longitudinal study.A version of this paper was presented at the 85th annual convention of the American Psychological Association, San Francisco, August 25–30, 1977.Received his Ph.D. in human development and family studies from Cornell University in 1973. Principal interests are the ecology of social development and child maltreatment. 相似文献

Responding to large wildfires requires actors from multiple jurisdictions and multiple levels of government to work collaboratively. The missions and objectives of federal agencies often differ from those of state land management agencies as well as local wildfire response agencies regarding land use and wildfire management. As wildfire size and intensity increase over time and associated annual suppression costs range between $2 billion and $3 billion, learning more about the existence and management of perceived agency differences becomes imperative within the academic and practitioner communities. This article examines the extent to which perceived mission misalignment exists among federal, state, and local actors and how well those differences are managed. Findings provide quantitative evidence that mission misalignment is greater within intergovernmental relationships than within intragovernmental relationships. Additionally, findings speak to the larger conversation around intergovernmental relationships within the federal structure and perceptions of the presence and management of potential interagency conflict.

- Potential conflict between the missions of federal and state land agencies presents a challenge for disaster management, and differing governmental levels and land‐use mandates may highlight relationships where tensions are likely greater.
- Wildfire managers may need to more proactively address relationships among federal agencies and state and local partners rather than relationships among multiple federal agencies.
- Wildfire management may benefit from increased awareness of—and discussion around—partner agencies’ stated land management philosophies and legal mandates, as structural frameworks, such as the Incident Command Structure, may not alone lead to conflict‐free collaboration.

The Digital Millennium Copyright Act (DMCA) offersseveral safe harbours that allow internet serviceproviders to limit liability for postings that allegedly constitutecopyright infringements. As a threshold to relying on one ofthese safe harbours, the internet service provider must reasonablyimplement a policy for removing content posted by repeat copyrightinfringers. 相似文献

ABSTRACTDrugging victimization is an understudied phenomenon. This study examines the relationship between the campus party culture and drugging victimization. Campus party culture has been shown to influence risk of other types of victimization, and there is reason to believe it may also influence drugging victimization. Using three behavioral indicators of participation in the campus party culture—binge drinking, Greek life membership, and first-year student status—this study estimates the main effect of each indicator, and their interaction, on undergraduates’ rates of drugging victimization. Estimating a generalized linear model using a large random sample (N = 6,931) from three universities, results show that each party culture variable and their three-way interaction significantly influenced students’ rate of drugging victimization. Sorority members who were first-year students and binge drank at least once in the past month had significantly higher rates of drugging victimization compared to all other groups of students. 相似文献

Currently, some philosophers and technicians propose to change the fundamental constitution of Homo sapiens, as by significantly altering the genome, implanting microchips in the brain, and pursuing related techniques. Among these proposals are aspirations to guide humanity’s evolution into new species. Some philosophers have countered that such species alteration is unethical and have proposed international policies to protect species integrity; yet, it remains unclear on what basis such right to species integrity would rest. An answer may come from an unexpected angle of rights issues: Some cultures have indicated that they want no part of our technological culture, preferring to retain their practices. Yet, rights documents do not explicitly establish that any individual has a right to species integrity. Careful interpretation of rights documents nonetheless reveals that such a right to species integrity is implicit. Interpreting these so as to reveal this needed right is also necessary to retain the foundations of rights documents and institutions. Further, acknowledging a right of species integrity could mean, because of practicalities, a limit to the freedom of proponents to implement proposals to manipulate the species. 相似文献

The effect of substrate interferences from high‐density polyethylene (HDPE) on the ability to associate an ignitable liquid residue with the corresponding liquid standard, using statistical procedures, is demonstrated. Gasoline, kerosene, and lighter fluid, at three different evaporation levels, were spiked onto HDPE and subsequently burned to generate simulated ignitable liquid residues (ILRs). Samples were extracted using a passive headspace procedure and analyzed by gas chromatography–mass spectrometry. The total ion chromatograms were subjected to data pretreatment procedures prior to principal components analysis and Pearson product moment correlation. Using the combination of these statistical procedures, simulated ILRs were successfully associated with the corresponding liquid type, despite the presence of compounds inherent to the HDPE substrate, as well as those resulting from pyrolysis of the substrate. 相似文献

Funded by the National Science Foundation and the National Nanotechnology Infrastructure Network (NNIN), this study asks qualitatively analyzes interviews with 48 nanoscientist users at four NNIN facilities. The main research questions were: (1) Do nanotechnologies pose unique social and ethical concerns?; (2) how are the risks associated with nanotechnology distributed among different human populations?; (3) what are specific policy steps that can be used to manage such risks? This study purposefully oversampled female scientists to correct for the historical underrepresentation of women in the nanotechnology workforce. By amplifying the voice of this science, technology, engineering, and mathematics (STEM) workforce minority, the policy discussion contained herein better reflects the concerns of the general population. The results, analyzed with the aid of qualitative data analysis software, yield interesting differences in risk characterization among the scientists and innovative policy suggestions for the nanoscience community and regulators alike. 相似文献
