Urbanization has been considered as a major threat to biodiversity, making its ecology of increasing interest. Many urban ecology studies have been developed in a short time-scale, measuring real-time patterns. However, long-term studies are imperative to understand the responses of some species to the urbanization process. In this study, we aimed to assess the information provided by a recent one-year citywide bird survey when compared to a published ‘historical’ bird list of a neotropical city (Xalapa, Mexico) that compiles information of the past three decades, mainly from urban greenspaces. Specifically, we contrasted species richness values and assessed differences in species composition between both lists. We recorded 51 species in the one-year citywide survey, representing ~15 % of those reported in the historical list. Nonetheless, the upper-bound confidence interval of the citywide survey richness prediction represented ~66 %. Most of the species recorded in the one-year citywide survey are insectivores and granivores, a pattern that agrees with previous findings that underline the importance of insectivores as part of urban bird communities in the Neotropics. Although we used robust methods to compare our one-year citywide bird list and the historical list for the city of Xalapa, we acknowledge the limitations of comparing them. However, our results shed some light on the kind and type of information that one-year citywide surveys can provide and the importance of long-term studies for comprehending the processes involved in biodiversity changes within urban areas over time. Undoubtedly, establishing long-term citywide surveys sampling birds and other biodiversity groups will allow us to better understand the response of biodiversity to urbanization over time. 相似文献

A significant number of children and adolescents engage in deliberate fire setting, beyond the scope of curiosity and experimentation. Interventions developed to respond to the needs of such fire setters generally involve educational and/or psychosocial approaches. Research evaluating the effectiveness of these interventions is dominated by outcome studies which rely on recidivism rates determined by either official records or parent reports. There has however, been no process evaluation studies published. This study presents a process analysis which aimed to identify the strengths and weaknesses of a Fire Awareness and Intervention Program in New Zealand, from the perspectives of program consumers. Qualitative research methods were employed, with data being derived from in-depth interviews with young people and their parents/caregivers. The analysis indicated that (a) the FAIP was generally regarded as a positive experience, (b) practitioners' qualities of empathy and understanding are important for developing rapport with the young people and their parents, (c) education-based intervention tailored to the young person's age and developmental level is important, (d) educational resources need to be updated and used flexibly to respond appropriately to the age and developmental level of the young person, and (e) inter-agency and intra-agency relationships need to be developed and maintained, with formal arrangements for reciprocal referral systems developed in order to respond to the needs of the clients. The resulting implications for service providers, along with future research are discussed. 相似文献

The aim of this paper is to examine what we know about the experience and outcomes of networked initiatives aimed at facilitating practitioner research. We outline the roles and significance of practitioner research within social work; review emerging understanding of practitioner research network initiatives; and draw conclusions from a comparative analysis of three such initiatives in Auckland, New Zealand, Arhus County, Denmark, and across Scotland. We consider the nature and challenges of practitioner research and a number of responses to how such work should be formulated and conducted. Central to our argument is an empirically informed consideration—from our separate and shared experiences—of how well networks enhance the process and consequences, and art and craft, of such research projects. 相似文献

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations. 相似文献

It is a year since the Statistics Authority came into being. Official statistics are now supposed to be independent and on course to be trustworthy—and transformed to serve not just government but society as a whole. Has it all worked out? Ian Maclean of the Statistics Users Forum says a start has been made, but progress has been slower than hoped. 相似文献

This paper relates computational commutative algebra to tree classification with binary covariates. With a single classification
variable, properties of uniqueness of a tree polynomial are established. In a binary multivariate context, it is shown how
trees for many response variables can be made into a single ideal of polynomials for computations. Finally, a new sequential
algorithm is proposed for uniform conditional sampling. The algorithm combines the lexicographic Groebner basis with importance
sampling and it can be used for conditional comparisons of regulatory network maps. The binary state space leads to an explicit
form for the design ideal, which leads to useful radical and extension properties that play a role in the algorithms. 相似文献

Australian research has demonstrated that students with a disability are more likely to remain out of the full‐time workforce. These research findings have been the catalyst for a call for a comprehensive career development and transition planning approach for all students with disabilities in schools as well as for employers to rethink the role of people with disabilities in the workforce. In the Australian context the transition from school for individuals with a disability is complicated by a disparate and fragmented group of service agencies providing a range of services, including employment, supported accommodation, recreation and leisure pursuits, as well as training and placement, along with, at times, a deep‐seated prejudice towards people with disabilities in the market place. This paper reviews a number of issues and challenges confronting individuals with a disability making the transition from school to the post‐school environment. 相似文献
