Human choices regarding land cover management practices may influence ecosystem services provided by urban green spaces. We
conducted a 2-year study to compare biological (weed, insect, and disease), aesthetic (lawn quality), and economic (lawn care
program cost) attributes of an integrated pest management (IPM) program, in which pesticides are applied on the basis of treatment
thresholds, with a standard program, in which pesticides are applied on a calendar basis without pest monitoring. Both programs
were managed by a professional lawn care operator. Although weed incidence was low, the IPM program had significantly more
lawns with weed presence than the standard program during 2005 and 2006. However, only 21% of the IPM lawns required herbicide
applications in 2005, and none exceeded the treatment threshold (5% weed cover) in 2006 as compared to 100% of the standard
program lawns being treated for weeds in both years. The IPM program also had significantly more lawns with insect damage
than the standard program during June 2005 and August 2005, but not September 2005 and throughout 2006. Only 28% of the IPM
lawns required insecticide applications in 2005 and none exceeded the threshold (5% insect damage) in 2006 whereas all of
the lawns in the standard program received insecticide treatments in both years. Rhizoctonia blight was present on some of
the lawns, but was not a common problem. Although lawn quality was high for both programs (>8, on a scale of 1–9), it was
significantly higher for standard than for IPM program lawns during 2005, and June 2006 and September 2006, but not August
2006. The annual lawn management costs were lower for the IPM (281.50) than the standard program (281.50) than the standard program (458.06). Thirty one percent
of the IPM program customers who continued with the study in 2006 did so because they were satisfied with the IPM program.
Among those who did not continue with the program, 33% cited weed or insect problems, while 33% expected better results. The
implications of these findings for implementation of IPM in professional lawn care are further discussed. 相似文献

The development of European Community administrative authority has greatly influenced the development of an evaluation culture among the southern and central member states of the European Union. The present case study from Spain provides an example of this diffusion through the use of an empowerment evaluation approach to build evaluation capacity within the context of rural development. The study focuses on the evaluation process over a 10-year period of three local development programs run by three local partnerships created in the rural areas of the Madrid region through the European LEADER initiative. Critical components of empowerment evaluation are discussed, as well as the impact, limitations, difficulties, and applicability of the approach to rural development in the European Union. Conclusions are presented concerning evaluation capacity building and the development of an evaluation culture. 相似文献

Systemic challenges within child welfare have prompted many states to explore new strategies aimed at protecting children while meeting the needs of families, but doing so within the confines of shrinking budgets. Differential Response has emerged as a promising practice for low or moderate risk cases of child maltreatment. This mixed methods evaluation explored various aspects of North Carolina's differential response system, known as the Multiple Response System (MRS), including: child safety, timeliness of response and case decision, frontloading of services, case distribution, implementation of Child and Family Teams, collaboration with community-based service providers and Shared Parenting. Utilizing Child Protective Services (CPS) administrative data, researchers found that compared to matched control counties, MRS: had a positive impact on child safety evidenced by a decline in the rates of substantiations and re-assessments; temporarily disrupted timeliness of response in pilot counties but had no effect on time to case decision; and increased the number of upfront services provided to families during assessment. Qualitative data collected through focus groups with providers and phone interviews with families provided important information on key MRS strategies, highlighting aspects that families and social workers like as well as identifying areas for improvement. This information is useful for continuous quality improvement efforts, particularly related to the development of training and technical assistance programs at the state and local level. 相似文献

AbstractWomen with children in the home are more likely to report experiencing intimate partner violence (IPV) compared to women without children in the home. Consistently, research has identified an association between maternal experiences of IPV and adolescent delinquency. While research has suggested that this link may be explained through parenting factors, there are limited studies exploring sequential mediators that may explain how maternal experiences of IPV are related to distal outcomes, such as adolescent delinquency. The present study investigated mechanisms that might explain the association between early maternal experiences of IPV and adolescent delinquency. Data were collected as part of the Fragile Families and Child Wellbeing Study (FFCWS), a longitudinal birth cohort study. Using a structural equation modeling approach, parenting stress and both physically and psychologically harsh parenting behaviors were examined as sequential mediators in the association between the latent construct of maternal experiences of IPV and adolescent delinquency. Findings supported one sequential mediation mechanism: maternal parenting stress at child age five and psychologically harsh parenting at child age nine mediated the association between maternal experiences of IPV and adolescent delinquency at child age 15. In contrast, support was not demonstrated for the other proposed sequential mediation mechanism: maternal parenting stress at child age five and physically aggressive parenting at year nine did not mediate the link between maternal experiences of IPV and adolescent delinquency child age 15. The present study suggests maternal parenting stress and psychologically harsh parenting behaviors should be examined when referred for psychological services for experiences of IPV. 相似文献

Since the mid‐1980s. Further Education has experienced deep transformations as the result of market driven reforms and the emergence of ‘new managerialism’ in the sector. The changes affected its governance, purpose, organisation and culture, and had deep influence on the relations and identities in the workplace. This paper explores the response of managers in selected Colleges of FE in England, and their discursive construction of new work identities. It is argued that in mediating the reforms, managers adopt a range of responses and position themselves differentially to the discourses of ‘managerialism’ and the ‘market’. From enthusiastically adopting entrepreneurial management, to resisting, or quietly re‐constructing vocabularies and practices to fit traditional models of professional practice, the managers in this study illustrate the contested nature of implementing reforms in the public sector, and the complex interplay between agency and institutional practice. 相似文献

Reinserting the professional into the study of globalizing professional service firms: the case of law 总被引:2,自引:0,他引:2
Abstract In discussions of the globalization of professional service firms there is an increasing recognition that understanding the ‘social construction’ of organizational architectures is essential. In this article we argue, using the management of transnational law firms as an example, that to understand effectively these social constructions we must reincorporate an understanding of the principles of professionalism into discussions. We highlight the importance of occupational autonomy to professionals and how this is likely to influence the strategies that global professional service firms use. We also point to what we term the ‘varieties of professionalism’ and the spatially variable professional projects that underlie the values and identities of lawyers. This reveals the way rational and efficient forms of organizing have to be adapted as a result of professional values and the diverse ideals and beliefs of lawyers in different international jurisdictions. 相似文献

Numerous studies of American news coverage of September 11, 2001, reported unsettling jingoistic and stereotyping tendencies in the stories. These findings are not surprising. Media critics have argued that news reflects “the interests of established political and economic elites” and is biased toward a “consensus of national values and ideology.”This paper explores how public relations educators in the U.S. and U.A.E. could take the lead in developing courses that explore the evolution of American and Middle Eastern cultures. It will analyze how adding cultural competency to the list of skills and competencies required in our educational programs presents an opportunity to educate a generation that will accept difference and value a global culture separate from national identity. 相似文献

The authors describe the critical issues that emerged during the first years of the National Rural Fellows Program at its academic base, the University of Massachusetts at Amherst Department of Landscape Architecture and Regional Planning, and how these issues were subsequently addressed.The Program is designed to provide intensive training leading to a Master's degree for adult minority professionals from rural backgrounds throughout the United States. As a case study, the paper has implications for other departments considering innovations of this sort. It particularly describes the pedagogical and socio-cultural issues regarding the education of adult minority professionals, the potential for new faculty perspectives to be gained from such interaction, and the challenge to traditional regional planning curricula for rural planning across the United States. 相似文献

A training project in a northern Canadian community providedan opportunity to examine participatory planning approachesand the meaning of work in First Nations communities. Focusgroups conducted three years after the unsuccessful interventionof a community economic development (CED) project suggest thatcomplex factors such as lack of support from community leadersand rate of pay for workers determine whether CED is alwaysappropriate in northern, First Nations contexts. 相似文献

Many early childhood education (ECE) programs seek to enhance parents' capacities to support their children's development. Using a meta-analytic database of 46 studies of ECE programs that served children age three to five-years-old, we examine the benefits to children's cognitive and pre-academic skills of adding parenting education to ECE programs for children and consider the differential impacts of: 1) parenting education programs of any type; 2) parenting education programs that provided parents with modeling of or opportunities to practice stimulating behaviors and 3) parenting education programs that were delivered through intensive home visiting. The results of the study call into question some general longstanding assertions regarding the benefits of including parenting education in early childhood programs. We find no differences in program impacts between ECE programs that did and did not provide some form of parenting education. We find some suggestive evidence that among ECE programs that provided parenting education, those that provided parents with opportunities to practice parenting skills were associated with greater short-term impacts on children's pre-academic skills. Among ECE programs that provided parenting education, those that did so through one or more home visits a month yielded effect sizes for cognitive outcomes that were significantly larger than programs that provided lower dosages of home visits. 相似文献

This article examines employee experiences with family and medical leave policies at an urban public transportation union work site in the United States. The case study focuses on the leave experiences among a sample population of 91 primarily African-American women transit workers, including reasons for taking or not taking leaves, decisions regarding how much leave time to take, and work impacts experienced after returning from leaves. The case study found that all respondents with new babies or ill children took leaves, as did 78% of those with illnesses and 39% of those with ill family members. Among those eligible to take leaves, the most frequent reason for not doing so was the lack of wage replacement. Knowledge of leave policies was minimal and not associated with the likelihood of leave-taking. These findings are discussed in terms of their workplace and community implications, including the need to expand the length and types of family leave coverage, the need for government-mandated paid leave, approaches for increasing employee knowledge of leave rights, and the need for continued research into leave experiences of minority populations. 相似文献

The Doubles, funded by the National Institute on Drug Abuse, is a seven-episode series of media tools designed to teach third and fourth grade students about the science of drug addiction. The program's curriculum is delivered via a set of videos, interactive CD-ROMs, workbooks, or an Internet site. This article examines the process used to develop The Doubles and argues that its success stems from the careful balancing of the needs of the funding agency, state and national curricular guidelines, and the target audience. 相似文献
