AbstractTo increase the effectiveness and efficiency of searches for information, accounting students, researchers, practitioners, and regulators could benefit from a Website devoted to the electronic access to journals. The site described here addresses such a need in the business discipline of accounting. On the site, the titles of over 470 journals are listed and categorized by topical areas within accounting. Then, within each accounting category, the journals are grouped according to their Internet accessibility. To provide the user with quick access to the various journals, the site provides links to the homepages of the various journals. Serials Review 2002; 28:201–205. 相似文献

Fisher information contained in record values, inter-record times and their concomitants from a sample of fixed size is derived in general and explicit expressions are deduced for some specific known bivariate classes of distributions. A comparison between fixed sampling and inverse sampling schemes with equal number of records and concomitants is also carried out. We also consider parameter estimation based on bivariate records and a small simulation study is done. 相似文献

While teen homelessness, like all homelessness, is increasing, there have been few solid estimates of the actual number of teens effected. A twofold methodology to count homeless teens was used in the Seacoast region of New Hampshire and Maine. Social service agencies were contacted to obtain a count of homeless adolescents, and over 3000 high school age teens were surveyed in the seacoast ofNew Hampshire and southwestern Maine to identify how many were homeless. By using different definitions of homelessness, it was found that a minimum of 5% of all teens in high school reported that they had been homeless sometime during the past year. When using a broadened definition of homelessness, it was found that 20% of the teens regularly stayed with others. However, this experience was not identified by social service providers, who reported that teen homelessness simply was not a problem in their communities. In order to more accurately describe the phenomenon experienced by teens, it is proposed that the term “homelessness” should be replaced with a more inclusive word, such as “housing distress.” 相似文献

Caribbean peoples have been migrating to the United States for over one hundred years. Since the liberation ofimmigration policy in 1965, migrationfrom the Caribbean has increased considerably and has presented with an interesting permutation. Many single mothers have migrated leaving young children behind until the mother’s situation is stable in the United States. Upon reunification of child and parent, there are reports ofmarked adjustment difficulties. This paper examines one such case, which was presented for mandated treatment. Issues around intention strategy and implementation are explored in detail with references to case history and clinical theory. 相似文献

The distribution of ant colonies within a community is often well defined, yet this distribution can change due to changing environmental conditions, resource availability, and colony growth. In this study, structure infesting ant communities were sampled for one year within three Puerto Rican housing developments of different ages. These developments represented environments in different stages of recovery after a disturbance (secondary succession). Spatial mapping was used to plot the distribution and abundance of ant communities within these developments. At the beginning of the study, the youngest housing development (1 year since construction), had the fewest number of species present (ave. 1.6 per house). The second housing development (4 years old) had a greater number of species (ave. 2.6 per house), and a greater sampling frequency (the same species collected at multiple houses) than Site 1. The oldest development (8 years old) had both the greatest number of species (ave. 2.7 per house), and sampling frequency of the three sites. In all developments, the number of species, sampling frequency, and ant biomass increased throughout the year as colonies grew and foraging ranges expanded. It was observed in all developments, that species coexistence also increased throughout the year. As colony populations increased, there was a greater occurrence of multiple species being collected at the same sample house. In the youngest development, the two most dominant species increased in numbers during the year and began to be collected from the same sample houses. Spatial diagrams documented that multiple species in the older housing developments (later stages of succession), also shared a common distribution. Even the most dominant species (S. invicta) in all three sites, did not exclude additional species from foraging within its established range. 相似文献

Two synchronous projects undertaken in 2011 examined the likely impact of increasing urban densification on invertebrate populations within urban settlement in Perth, Western Australia. One project analysed the ant fauna found in 20 gardens and lawns in small to very small properties (these having a bungalow or duplex (semi-detached) as the main residential building, and a lawn or garden area of 43 m2–332 m2) east, south, north and west of the Central Business District (CBD). The other project examined the ant fauna at 14 sites, principally in native regrowth along the Kwinana Freeway, a major artery that runs north to south through Perth’s suburbs. The gardens and lawns produced a very depauperate fauna of 26 ant species, of which a maximum of 20 were native and at least six species were exotic. The ant fauna from regrowth adjacent to the Kwinana Freeway and at two additional sites (one a bush control) was more than twice as rich, the 56 species collected including only two exotics. In the garden project, ant richness, evenness and abundance were not significantly correlated with size of the garden area. The same applied even when the exotic Pheidole megacephala-dominated gardens were removed from the analysis. Ordination analysis combining the two sets of data revealed a distinct clustering of most of the regrowth sites, whereas the bush control stood alone and garden or lawn sites exhibited a much looser pattern of association. We suggest that increasing the density of Perth suburbs is resulting in drastic loss of native invertebrate fauna, of which ants are a useful bioindicator. However, native vegetation regrowth along major arterial roads could act as a reservoir for invertebrate species that might otherwise disappear entirely from the Perth metropolitan area. 相似文献

This study compares the efficacy of experimental, competency-based methods of teaching the interpersonal skills of empathic communication, respect, and genuineness with traditional didactic methods. An experimental design using randomly-chosen experimental and control groups of first-year graduate students was employed. Experimental conditions involved communication laboratories consisting of didactic and experiential learning opportunities organized in a systematic and sequential fashion. The findings supported the hypothesis that the experimental groups would significantly outperform the control groups on the criterion variable. A second hypothesis, that the control groups would not achieve significant gains, was refuted. 相似文献
