Understanding innovation performance and its antecedents: A socio-cognitive model

Little attention in the previous literature has been paid to understanding employees’ factors that drive customer development knowledge and performance from the perspective of social psychology. Drawing on social cognitive theory, this study validates a research model that examines the above issue. In the setting of new product development across high-tech firms in Taiwan, this study postulates that innovation self-efficacy, role conflict, and role ambiguity influence innovation performance directly and indirectly via the mediation of customer knowledge development and innovation outcome expectation. This study contributes to the social science literature by applying social cognitive theory to the rarely explored area of innovation performance and by presenting an operationalization of role stressors (i.e., role ambiguity and role conflict) in the area. Lastly, managerial implications and limitations from the empirical findings are provided.     

Gender difference in physical performance, body composition and dietary intake in homebound elders

Considering that the most vulnerable subgroup of elders for poor nutritional status and functional decline is the increasing number of homebound women, we examined gender differences in physical performance, body composition, and dietary intake in a randomly recruited sample of 345 homebound elders (81% women, 48% black, > 65% income < $750/month). After controlling for demographic and health-related factors, the results from multivariate analyses indicated that women were more likely than men to report the lowest nutrient intake and were 2.9 times more likely to be at the worst level of overall physical performance. These results suggest a heightened vulnerability of homebound older women to poor physical performance, low dietary intake, and increased Body Mass Index (BMI). Prospective research is now needed to examine the interrelationships between physical performance, dietary intake, and body composition among the growing homebound older population.     

Testing local level labor force and unemployment projections

The labor force projections perform well, even for small areas, which suggests that changes in local labor force participation rates can be approximated by national changes. In fact, the mean absolute percent errors are low even when the previously calculated population projections are used. The unemployment projections do not do as well, and using 1980 census labor force data instead of previously calculated labor force projections offers no improvement in the results. A two-step study is needed to determine why the errors are so large. First, the state level changes from 1970 to 1980 should be compared with national changes to determine the difference in unemployment rate changes by race and sex. Second, state level data on the occupational mix should be examined for the relationship between this and the changes in state level unemployment rates by race and sex. It is hypothesized that the first step will show that even state level changes in unemployment rates by race and sex cannot be well approximated by the national changes and the second step will show that some of the variation can be explained by state differences in occupational mix. Further studies should be made to determine how the calculation of national changes affects the results. Changes in labor force participation rates seem to follow trends, and therefore extrapolation may not have much effect on the results. Although using the actual changes in unemployment from 1970 to the latest year available as a proxy for the changes from 1970 to the target year may have a serious detrimental effect on the unemployment projections, if some of the variation in the national changes in race and sex can be explained and some adjustments made, the actual changes may be the best proxy to use.     

Protective supervision: An inquiry into the relationship between child welfare and the court system

Protective Supervision, in most states, is defined in statute as an option in which the child is allowed to remain in the home of high-risk parents under the authority of the court, with supervision provided by the child protection system. Protective Supervision provides states an option to fulfill the federal mandate, as expressed in its guidance on the Child and Family Services Review, to assure that children are safely maintained in their homes whenever possible and appropriate. Nevertheless, there is a paucity of published work on this option. Further, the relationship between child protection and the judicial system, implicit in Protective Supervision, is rarely examined. In response to this dearth of information, an exploratory study was undertaken in Minnesota, funded by the Minnesota Department of Human Services. Data were derived from focus groups in every region of the state, with both child protection and judicial system participants. This study offers insights into the complicated nature of the partnership between two complex systems — child welfare and the court system. Currently, there is wide variation in how Protective Supervision is understood and practiced. However, where there is mutual respect between child welfare and the courts, Protective Supervision offers a useful tool.
