The paper contends that environmental planning concern and other developmental efforts are inseparable. In view of the delicate balance between man and his physical environment, Nigeria must develop a growing and more realistic approach to environmental planning and education: the elements it should be made from, how it should be done, and who should receive it are enunciated. The problems of data and implementation as well as their legislative, public participation and other implications are analysed.  相似文献

Infectious particles can be deposited on surfaces. Susceptible persons who contacted these contaminated surfaces may transfer the pathogens to their mucous membranes via hands, leading to a risk of respiratory infection. The exposure and infection risk contributed by this transmission route depend on indoor surface material, ventilation, and human behavior. In this study, quantitative infection risk assessments were used to compare the significances of these factors. The risks of three pathogens, influenza A virus, respiratory syncytial virus (RSV), and rhinovirus, in an aircraft cabin and in a hospital ward were assessed. Results showed that reducing the contact rate is relatively more effective than increasing the ventilation rate to lower the infection risk. Nonfabric surface materials were found to be much more favorable in the indirect contact transmission for RSV and rhinovirus than fabric surface materials. In the cases considered in this study, halving the ventilation rate and doubling the hand contact rate to surfaces and the hand contact rate to mucous membranes would increase the risk by 3.7–16.2%, 34.4–94.2%, and 24.1–117.7%, respectively. Contacting contaminated nonfabric surfaces may pose an indirect contact risk up to three orders of magnitude higher than that of contacting contaminated fabric surfaces. These findings provide more consideration for infection control and building environmental design.  相似文献

Two national U.S. telephone surveys of gambling were conducted, an adult survey (age 18 and over, N = 2,631) in 1999–2000 and a youth (age 14–21, N = 2,274) survey in 2005–2007. The data from these surveys were combined to examine the prevalence of any gambling, frequent gambling and problem gambling across the lifespan. These types of gambling involvement increased in frequency during the teens, reached a high level in the respondents’ 20s and 30s, and then fell off in as the respondents aged. The notion that gambling involvement generally, and especially problem gambling, is most prevalent during the teens was not supported. A comparison of the age patterns of gambling involvement and alcohol involvement showed that alcohol involvement peaks at a younger age than gambling involvement; and thus, the theory that deviant behaviors peak at an early age applies more to alcohol than to gambling.  相似文献

I use the metaphor zebra crossing in my reflective narrative to describe my plight and struggle as a non-white person growing up and working in Johannesburg, South Africa, during the apartheid era. This article considers and compares the notions of culture, diversity and identity as I now work in a tertiary institution in Melbourne, Australia. I reflect on my teaching of African music and position myself as ‘the other’ at zebra crossings, as I create a space in multicultural Australia. By engaging in meaningful dialogue with music and culture, I contend, we do have opportunity to explore, experience and express music making and sharing globally. The inclusion and embracing of non-western music can serve as a dais for understanding and celebrating cultural difference not as distant experiences but as integral aspects of our daily lives.  相似文献

In this article, the author reviews current scholarship on the cultural construction of heterosexual identities. Specifically, this article examines current research on how heterosexual identities are (i) central to the production of the ritual practices of marriages, weddings and high school proms; (ii) ever more salient due to increases in lesbian and gay visibility in America; and (iii) formed through their relationship with constructions of masculinity and discourses of homophobia. Finally, I briefly discuss new scholarship on queer heterosexualities as a way to illustrate how queer cultural studies are influencing the field of sexualities studies more generally.  相似文献

There exists a healthy debate about the process and value of substantiation in child welfare. Much of this debate focuses on understanding whether substantiated and unsubstantiated allegations of maltreatment share equal risk of recurrence. In the current study we seek to advance this debate by extending the analyses to focus specifically on the risk of juvenile delinquency. We also seek to determine whether the relationship between substantiation and delinquency varies by race and gender. Our sample includes 38,223 youth between 5 and 16 years of age from Los Angeles County. We use propensity score matching to create relatively equivalent groups and use Cox Regression to model the risk of juvenile arrest. The results indicate that the relative risk ratio of arrest is 2.2 times greater for youth associated with a substantiated report of maltreatment as compared with similar youth associated with an unsubstantiated report of maltreatment. Older youth, and African American youth are also at an increased risk of juvenile arrest. These findings indicate that the process of substantiation is not without merit - as investigators and supervisors are clearly able to distinguish cases based on individual risks and strengths.  相似文献

Belief in angels and their intervention in the material world is prevalent in the United States. Theoretically, the concept of folk religion offers an instructive lens into the popularity of these beliefs, which exist inside, outside, and across official religious doctrines, and are therefore able to transcend the boundaries of specific religious traditions by appealing to a diverse array of believers. Empirical analyses from a recent national survey support the application of the concept of folk religion, demonstrating that these beliefs are present in substantial proportions across disparate subgroups. Belief in angelic intervention is prevalent among conservative and “mainline” Protestants, Catholics, those with high levels of conventional religious practice, biblical literalists, and even those who strongly believe in “paranormal” phenomena such as Bigfoot and ESP. Belief in angels and claims of angelic protection provide compelling and flexible narratives, ready cognitive attributions, and emotional comfort. Consequently, these views have strong memetic appeal and are transposable into multifarious subcultures.  相似文献

Historically, data concerning children reported for abuse or neglect in the US have been compiled by child protective service agencies and analysed independently from other sources of information. Yet these data suffer from the notable limitations of being both narrow in scope (i.e. containing a limited set of variables) and narrow in coverage (i.e. capturing data for only those children who are reported). In order to extend an understanding of children reported for maltreatment, the California Department of Social Services, in partnership with the University of California at Berkeley, is pursuing a ‘public health’ oriented approach to the surveillance of child maltreatment through linkages between child protective service records and population‐based sources of data. As an example of the information that can be generated through linked records, this article reports results from child‐level matches completed between the state's child protective service records and vital birth records. The cumulative percentage of children reported for abuse or neglect before the age of five is examined based on maternal and child characteristics at birth. This is followed by a discussion of record linkages as a means of furthering a public health approach to child maltreatment. Copyright © 2011 John Wiley & Sons, Ltd.
