This study analyses the effectiveness of the European Community's Environmental Assessment Directive of 1985 in its application in the U.K. forestry sector. It assesses the applicability of the regulations in the provision of the public and private outputs of forestry. The environmental assessment regulation may contribute to the provision of the optimal amount of these public and private goods in theory, but it is concluded that, in common with initial results of the environmental assessment process in other sectors, the regulations do not make this contribution in practice in the forestry sector. The main deficiencies of the environmental statements examined were the failure to identify the significant potential impacts; to present alternative project sites and design features; and the erroneous measure of particular externalities. The environmental assessment process was also found to be unsatisfactory in the lack of public accessibility and consultation. The need for revision of the process in the forestry sector is highlighted. 相似文献

In this paper the choice between marriage and unmarried cohabitation as a first union by young adults is studied. A hazard analysis is performed on a sample of 590 26-year-old men and women from the Netherlands. Students are much less likely to start a union in general, and marriage in particular, than are other categories of young adults. Young adults living at home are less likely to enter a consensual union than those living on their own. Religious young adults are much less likely to enter a consensual union and much more likely to marry than are non-religious ones. Educational attainments at age 16 do not influence union formation.Cet article étudie le choix des jeunes adultes entre mariage et cohabitation pour leur première union : une analyse, utilisant un modèle à risques proportionnels, est effectuée sur un échantillon de 590 jeunes hommes et jeunes femmes âgés de 26 ans en Hollande. Les étudiants ont une plus faible probabilité de s'engager dans une union en général, et plus particulièrement dans un mariage, que les autres catégories de jeunes. Les jeunes vivant chez leurs parents ont également une plus faible probabilité d'entrer dans une union consensuelle que ceux vivant indépendamment. Enfin les jeunes qui pratiquent une religion ont une plus faible probabilité d'entrer dans une union consensuelle et une plus forte probabilité de se marier que les non pratiquants. En revanche le niveau d'éducation à 16 ans n'a aucune influence sur les unions à venir.

Using asymptotic expansions of the Kummer hypergeometric function, the sequential. F-test criterion is evaluated asymptotically in terms of the sample size. The continuation region inequalities for the test are inverted and expressed in terms of known test criteria. A rapidly converging algorithm for carrying out the sequential procedure is provided. This makes the F-test easier for the practitioner to use. Almost sure finite termination of the sequential. F-test is asserted by appealing to the continuation inequalities and a heuristic asymptotic expansion of the test criterion. Average stopping times of the sequential procedure for a variety of population means and population number configurations are tabulated. The computer symbolic manipulation program MAPLE was used to derive some formulae. 相似文献

The study is conducted to determine families' rankings of characteristics they consider most important when selecting a nursing home. Friedman's two-way analysis of variance is used to test for differences in the rankings. In response to a mailed survey, 231 families rank the characteristics in the following order: quality of care, appearance, atmosphere, location, reputation, building safety, quality of food, cost, and activities. Relationships are also found between the rankings and the demographic characteristics: gender, marital status, education, income, number of homes available, patient/respondent relationship, and distance respondent lived from the chosen home. 相似文献

An exact conditional test is developed for testing the absence of an edge in a graphical covariance selection model and is shown to be equivalent to a test based on the partial correlation coefficient. An example is given. 相似文献

Trends in tolerance are tested for groups on the Right and onthe Left of the political spectrum with 1976–88 GeneralSocial Survey data. Findings are that (1) tolerance increasedtoward leftist groups but not toward rightist groups; (2) succession,the replacement of older cohorts by more recent cohorts, increased tolerance toward leftists and rightists alike, partiallyon account of more recent cohorts' higher levels of education;and (3) attitude change within cohorts reduced tolerance butonly toward rightists. Overall, trends toward greater toleranceseem not to be mere reflections of reduced opposition to unpopulargroups but instead reflect changes in willingness to allow expressionof opposed ideas. 相似文献

A review of The Career Development Quarterly was conducted for a 20-year period (Volumes 23 through 42). A total of 791 articles were classified into the 14 substantive areas of career research and practice devised by Fitzgerald and Rounds (1989). Author institutional affiliation, geographic location, and leading contributors were also computed. Two principle areas of research activity and publication were evident (life-span perspectives on career development, and career development interventions), which accounted for 51.2% of the articles examined. Overall, Quarterly content has remained stable and no clearly definable trends across the years were apparent in any given topic. 相似文献
