The invertebrate fauna in artificial urban habitats has yet to be systematically investigated. The current field study in
central Ohio was undertaken to assess the numbers and types of macroinvertebrates in mulched and unmulched plots during a
one-year period. Invertebrates quickly infiltrated the plots with bare soil (control) and any of four types of mulch (shredded
hardwood, shredded recycled wood, pine bark mini-nuggets, and pea gravel). One month after establishing the plots, invertebrates
were present in numbers comparable to subsequent months. Invertebrates found in the plots were primarily saprophytic taxa:
millipedes (32.6%), segmented worms (19.8%), isopods (6.7%), and various beetle families (1.5%). Predatory taxa included centipedes
(9.8%), ants (9.7%), carabid beetles and staphylinid beetles (7.3%), and spiders (0.9%). Types of invertebrates were similar
in all ground cover types, but numbers of invertebrates differed significantly. Invertebrates were present year-round in mulched
plots, and plots with organic mulch harbored significantly more invertebrates than plots mulched with pea gravel. Bare soil
always contained the fewest number of invertebrates. There was no significant difference in numbers of invertebrates based
on the cardinal side of the building. 相似文献

Many countries of emigration are in transition from conflict to peace and from authoritarian to democratic governments. Addressing population movements from these countries requires more than economic opportunities; equally important is the establishment of the rule of law, respect for human rights, and, in countries recovering from conflict, reconstruction of destroyed infrastructure and housing. Otherwise, fragile peace and democratization processes can easily break down, creating new waves of forced migrants and hampering efforts towards repatriation and reintegration of already displaced populations. This background paper discusses the nature of forced migration, pointing out that the end of the Cold War has produced new pressures and new opportunities to address these flows. While extremism, particularly rampant nationalism, has provoked massive forced migration in many parts of the world, the changing geopolitical relations has also led to peace settlements in some countries and humanitarian intervention to reduce suffering in others. Addressing forced migration pressures in countries in transition requires comprehensive policy approaches. Four types of best practices are considered in this paper. First, mechanisms to ameliorate the causes of forced movements, including the role that expatriate communities can play in strengthening the rule of law and respect for human rights, particularly minority rights. Second, mechanisms that enhance refugee protection while minimizing abuses of asylum systems, including enhanced respect for the refugee convention, adoption of complementary forms of protection when the refugee convention does not apply, strengthened regional protection, and the establishment of in–country processing of refugee claims. Third, mechanisms to resolve the longer–term status of forced migrants, including decisions on when to cease refugee status and temporary protection and encourage/permit return or integration. Fourth, mechanisms for more effective repatriation when return is possible, particularly programs to help returnees reintegrate and communities reconstruct themselves. 相似文献

Behavioral staff at a school for children with autism investigated the effects of a brief behavioral skills training procedure to promote the appropriate administration of the EpiPen in an emergency situation by school staff. A 10-item task analysis was created outlining the steps required to use the EpiPen effectively and safely and was validated by the school’s registered nurse. Following a pretest in which members of both groups completed a minimal number of steps, the experimental group was trained via instructions, modeling, praise, feedback, and role playing to correctly use the EpiPen whereas the control group received no such training. Posttest scores indicated that the brief intervention was an effective means of teaching appropriate administration of the EpiPen with school staff. 相似文献

R&D (Research and Development) activities represent the basic core of corporate science and technology activities, and play a crucial role in enhancing the ability of companies to achieve rapid and sustainable growth. In recent years, the total R&D investments in China have increased significantly and the proportion of the industrial investments in R&D activities relative to national R&D investments has increased rapidly. In order to investigate the effectiveness of these R&D investments, we utilize Data Envelopment Analysis (DEA) models to evaluate the relative efficiencies of 30 regional R&D investments using the First Official China Economic Census Data in 2004. Our investigation and study indicate the following: (1) Only six provinces are global technical efficient and the performance of regional R&D investments in China needs to improve dramatically. (2) Increasing returns to scale have not yet occurred in any province. Constant returns to scale have prevailed in most provinces in the Western region, and decreasing returns to scale have prevailed in most provinces in the Eastern and Central regions. (3) There are no direct relationships between global technical efficiency and the amount of R&D investment. The Western region has the highest average radial efficiency score, followed by the Eastern region, and then by the Central region. (4) The Eastern region has advantages in local technical efficiency, the Western region has advantages in scale efficiency, while the Central region has neither technical efficiency advantages nor scale efficiency advantages. Suggestions are proposed to improve efficiencies of regional R&D investments. 相似文献

We investigated whether maternal mind‐mindedness in infant–mother interaction related to aspects of obstetric history and infant temperament. Study 1, conducted with a socially diverse sample of 206 eight‐month‐old infants and their mothers, focused on links between maternal mind‐mindedness and (i) planned conception, (ii) perception of pregnancy, and (iii) recollections of first contact with the child. The two indices of mind‐mindedness (appropriate and nonattuned mind‐related comments) related to different aspects of obstetric history, but no strong associations were seen with socioeconomic status, maternal depression, or perceived social support. In Study 2, we found good temporal stability in both indices of mind‐mindedness in a sample of 41 infant–mother dyads between 3 and 7 months. Neither index of mind‐mindedness related to infant temperament. We conclude that mind‐mindedness is best characterized as a facet of the specific caregiver–child relationship, while also being influenced by stable cognitive–behavioral traits in the mother. 相似文献

The purpose of this article is to describe empathy as a complex construct, and its implications for practice. A review of
current literature affirms the central role of empathy in psychotherapy, and the importance of mastering it for effective
practice. Contributions from perspectives of attitude, context and social neuroscience converge to suggest a dynamic complex
construct, useful as a framework for practice application. Influenced by factors such as attitudes, contexts, and values,
the quality of empathic engagement is shown to emerge from their unique mix, within and between therapist and patient, and
is always grounded in shared, embodied humanity. The essential role of the therapist’s self-regulation is demonstrated. A
number of strategies for more consciously managing empathic engagement, and for balancing affect-regulation challenges with
self-care are described. 相似文献

Participation of extended family members, particularly custodial grandparents, has generally resulted in better outcomes for abused children and relief for an overburdened child welfare system. This research explores the risk of adolescent perpetrated violence in custodial grandparent households with data from the Florida Department of Juvenile Justice. Findings suggest that living arrangements with custodial grandparents have a significant and differential impact on rates of violent offending for chronic and serious offenders by race and gender. 相似文献

In this article, we present a theory-based application of clinical simulation in psychiatric-mental health nursing education. As described by Benner, Sutphen, Leonard, and Day, a three-pronged apprenticeship that integrates intellectual, practical, and ethical aspects of the professional role is critical in the development of practical reasoning in nursing education and training. Clinical encounters are often fraught with ambiguity and uncertainty. Therefore, educating for a practice discipline requires experiential and situated learning. Using the three-pronged experiential model in simulated psychiatric-mental health nursing practice supports the development of critical nursing skills, ethics, and theoretical concepts. A clinical scenario is presented that demonstrates the application of this model of professional apprenticeship in psychiatric-mental health education. Applications of the concept presented may be used in training nurses new to the practice of psychiatric-mental health nursing. 相似文献
