The authors examined perceptions of key social cognitive career theory (Lent, Brown, & Hackett, 1994) variables related to college‐going and science, technology, engineering, math, and medical (STEMM) careers in 10th and 11th graders (N = 892) attending 3 rural Appalachian high schools. The authors examined differences in perceptions related to gender, prospective 1st‐generation college student status, and the presence or absence of aspirations to pursue a STEMM career. Young women and young men scored similarly on all but 1 dependent variable, college‐going self‐efficacy (young women scored higher). Students who had STEMM career aspirations had higher scores on every measure than those who did not. Results suggest examining a 3rd prospective 1st‐generation college student status group—students who are unsure of their parents’ education level—as a distinct group in future research. By examining the college‐going and STEMM attitudes of rural Appalachian high school students, this study advances the literature and informs practitioners on reducing educational and vocational inequalities in this region. 相似文献

The initial version (v1) of the Fish Invasiveness Scoring Kit (FISK) was adapted from the Weed Risk Assessment of Pheloung, Williams, and Halloy to assess the potential invasiveness of nonnative freshwater fishes in the United Kingdom. Published applications of FISK v1 have been primarily in temperate‐zone countries (Belgium, Belarus, and Japan), so the specificity of this screening tool to that climatic zone was not noted until attempts were made to apply it in peninsular Florida. To remedy this shortcoming, the questions and guidance notes of FISK v1 were reviewed and revised to improve clarity and extend its applicability to broader climatic regions, resulting in changes to 36 of the 49 questions. In addition, upgrades were made to the software architecture of FISK to improve overall computational speed as well as graphical user interface flexibility and friendliness. We demonstrate the process of screening a fish species using FISK v2 in a realistic management scenario by assessing the Barcoo grunter Scortum barcoo (Terapontidae), a species whose management concerns are related to its potential use for aquaponics in Florida. The FISK v2 screening of Barcoo grunter placed the species into the lower range of medium risk (score = 5), suggesting it is a permissible species for use in Florida under current nonnative species regulations. Screening of the Barcoo grunter illustrates the usefulness of FISK v2 as a proactive tool serving to inform risk management decisions, but the low level of confidence associated with the assessment highlighted a dearth of critical information on this species. 相似文献

Wilderness,a probe into "cultural carrying capacity" 总被引:1,自引:1,他引:0
Garrett Hardin 《Population and environment》1988,10(1):5-13
Population policy for human beings must be governed by a commitment never to transcend the cultural carrying capacity. Determining this capacity is a problem in values. As concerns material goods, the cultural carrying capacity is inversely proportional to the quality of life demanded. Inherently scarce goods like wilderness, which can be enjoyed by only a few, pose this ethical problem: can we agree on a basis for choosing an elite, or must we, like the French revolutionary Gracchus Babeuf, insist on equal distribution even if the only possible allotment is then zero? If we reject Babeuf we must recognize that the maximum population cannot be the optimum. 相似文献

Box's paper helicopter has been used to teach experimental design for more than a decade. It is simple, inexpensive, and provides real data for an involved, multifactor experiment. Unfortunately it can also further an all-too-common practice that Professor Box himself has repeatedly cautioned against, namely ignoring the fundamental science while rushing to solve problems that may not be sufficiently understood. Often this slighting of the science so as to get on with the statistics is justified by referring to Box's oft-quoted maxim that “All models are wrong, however some are useful.” Nevertheless, what is equally true, to paraphrase both Professor Box and George Orwell, is that “All models are wrong, but some are more wrong than others.” To experiment effectively it is necessary to understand the relevant science so as to distinguish between what is usefully wrong, and what is dangerously wrong.This article presents an improved analysis of Box's helicopter problem relying on statistical and engineering knowledge and shows that this leads to an enhanced paper helicopter, requiring fewer experimental trails and achieving superior performance. In fact, of the 20 experimental trials run for validation—10 each of the proposed aerodynamic design and the conventional full factorial optimum—the longest 10 flight times all belong to the aerodynamic optimum, while the shortest 10 all belong to the conventional full factorial optimum. I further discuss how ancillary engineering knowledge can be incorporated into thinking about—and teaching—experimental design. 相似文献

New legal options to prepare adolescents for independent living 总被引:2,自引:0,他引:2
M Hardin 《Child welfare》1988,67(6):529-546
New legal alternatives are needed to assist older adolescents living apart from their families to make the gradual transition to self-sufficiency. At present, there are only two legal alternatives for such adolescents in most states: agency legal custody (foster family or group care) and emancipation. Two new alternatives are needed to allow mature young persons to practice limited independence and to receive some continued aid and supervision from child welfare agencies: independent-living arrangements and special programs for young adults formerly in agency custody. 相似文献

Day shelter programs are an important resource for people experiencing homelessness, offering respite from inclement weather, social stigma, victimization, and access to essential services and resources. Creating functional day shelter spaces requires that staff, services, and facilities support the needs of this vulnerable and marginalized population. Little guidance, however, is available regarding the design of day shelter spaces that support service engagement and positive service outcomes. This systematic review was conducted to support the development of a new day shelter in Fort Worth, Texas, identifying and reviewing interdisciplinary resources relevant to the design of these facilities. Based on the review, a preliminary taxonomy emphasizing day shelter client safety, security, dignity and health and well-being is proposed. Additional discussion identifies practical considerations affecting the implementation of the taxonomy, design priorities, and how the taxonomy was applied to the design of the Fort Worth day shelter. 相似文献
