This article examines the effect of product development restructuring (PDR) on shareholder value. The results are based on a sample of 165 announcements made during 2002–2011. PDR announcements are associated with an economically and statistically significant positive stock market reaction. Over a two‐day period (the day of the announcement and the day preceding the announcement), the mean (median) market reaction is 1.63% (0.87%). The market reaction is generally positive regardless of the PDR purpose or action. Although the market reaction is more positive for higher R&D intensity firms, it is not directly affected by the firm's prior financial performance or whether the firm's primary PDR objective is to increase revenues or cut costs. However, the interaction between the firm's prior financial performance and its primary PDR objective is significant. For firms that are financial outperformers, the market reaction is more positive if the firm's primary PDR objective is to increase revenues. For financial underperformers, the market reaction is more positive if the firm's primary PDR objective is to cut costs. 相似文献

The purpose of this paper is to determine the effects of off-farm employment on perceptions of quality of life. Data collected on 311 Western Ontario male and female farmers revealed that although most indicated satisfaction with their lives, some differences are apparent. Women employed off the farm report more areas of lower satisfaction than their male counterparts and men and women working solely on the farm. Low levels of satisfaction with time issues, leisure and exercise were most evident for employed women. Men employed off the farm report the most effects from time issues, satisfaction with the farm business, income and the environment. People working off the farm feel their farms are less successful and are more concerned with their environment. Whereas the farm family's pluriactivity enables many to hold on to herished aspects of the farming lifestyle for a while, its burdens are perceived to fall neaviest on female farmers especially if they have young children. The magnitude of their concerns about the quality of their environment and not being able to farm successfully suggests that many of these farmers would improve their quality of life by peeding up the transition out of farming before all their farm's equity is lost. 相似文献

The current economic and social context calls for a renewed assessment of the consequences of an early transition to parenthood. In interviews with 55 teenage mothers in Colorado, we find that they are experiencing severe economic and social strains. Financially, although most are receiving substantial help from family members and sometimes their children's fathers, basic needs often remain unmet. Macroeconomic and family structure trends have resulted in deprived material circumstances, while welfare reform and other changes have reduced the availability of aid. Socially, families' and communities' disapproval of early childbearing negatively influences the support young mothers receive, their social interactions, and their experiences with social institutions. 相似文献

Suicidal behavior among children and adolescents is a national problem and schools can be an effective context for suicide prevention and intervention efforts. School-wide screening programs are viewed as most effective from a public health standpoint, although they garner the least support from school administrators. The purpose of this article is to examine administrators' perceptions of three school-based suicide prevention models while also capturing opinions on barriers and benefits to implementation. Data were gathered through interviews with seven principals from one Midwestern state. Findings reveal agreement among principals that schools play a key role in suicide prevention, but they differ on which type of prevention approach is most appropriate. School principals believed the school-wide screening program included more barriers to implementation than either the in-service or the curriculum-based program, largely due to the likelihood of parental disapproval. Limitations of the study and implications for improving suicide prevention efforts are discussed. 相似文献

In the midst of the current economic crisis, there is renewed interest in transforming vacant lots into food-producing gardens.
This study analyzed whether vacant lots are suitable for food production, by comparing the soil nematode food webs and nutrient
pools of vacant lots and community gardens in two post-industrial U.S. cities, Akron and Cleveland, Ohio. Twelve vacant lots
and 12 community gardens were examined in the two cities. All six Akron community gardens were established just prior to the
initiation of this study, whereas the six in Cleveland were 15–30 years old. Soil pH, texture, moisture, organic matter, mineral
nitrogen content, microbial biomass, and nematode communities were measured in both cities. Soil decomposition rate was also
measured in Cleveland. Results show that the soils of vacant lots surpassed those of the newly-established Akron gardens and
were equal to the soils of the well-established Cleveland gardens in the amount of ammonium-nitrogen, total nematode population,
genus diversity, and maturity and structure indices. The soils of the vacant lots were lower than the community gardens in
the amounts of soil moisture, organic matter, and nitrate-nitrogen, which we associate with the addition of water, compost,
fertilizer, and tilling in the gardens. No significant difference was found between community gardens and vacant lots in microbial
biomass, decomposition rate, or nematode enrichment index, which seems to indicate that vacant lots are equal to community
gardens in nutrient availability and nutrient cycling. We conclude that barring any contamination, the soil in vacant lots
maybe suitable for the establishment of food gardens, which can provide many desirable ecosystem services and enhance human
well-being. We also find that the disturbance associated with tillage and conversion of a vacant lot into a community garden
has short-term ramifications for both nematode food webs and mineral-nitrogen content. 相似文献

While the literature supports the importance of establishing a relationship between designers and subject matter experts (SMEs) in the training design process, this approach is not followed in all global practices. The purpose of this study was to identify the perceptions of human resource development professionals in Taiwan regarding their working relationships with SMEs. The respondents of the study were HRD professionals who worked in high-tech companies located in a science park in Taiwan. The study found that a significant relationship exists between the ability to work with SMEs and current ability in the training design process among HRD professionals who had worked with SMEs. This study provides implications for the professional development of HRD practitioners and HRD practice in Taiwan companies. Cross-cultural issues are discussed to explain inconsistencies between the results and US-based perspectives on the training design process. 相似文献
