This study attempted to identify the primary activities performed by R&D managers at different supervisory levels, and the cognitive and interpersonal ability requirements that underlie these activities. A task inventory containing 244 managerial tasks was completed by 117 R&D managers in nine organizations. The 48 tasks which managers rated as having spent the most time were factor analyzed, resulting in the identification of three primary activities: project management, personnel supervision, and strategic planning. Furthermore, these activities varied with supervisory level, with R&D managers performing a wider range of these activities with the progression from first-line to upper-level management.Thirty R&D managers later rated the degree to which 19 cognitive and interpersonal abilities were required for performing these primary activities. Strategic planning was rated as requiring significantly higher levels of oral expression, logical reasoning, originality, fluency of ideas, oral defense, and resistance to premature judgement than was required for the other two primary activities. Personnel supervision required a higher level of social sensitivity than was required for the other two activities. Project management required high levels of information ordering, oral fact- finding ability, problem sensitivity, and oral and written comprehension. Implications of the findings for understanding R&D managerial performance and personnel staffing functions are discussed.  相似文献

There is growing recognition in the nonprofit field that the executive director has a key role in determining whether the board of directors will function effectively. To aid executives in this vital role, two recent studies defined a "good board" from the point of view of two samples of executive directors of community agencies, then sought factors related to board performance as measured by this definition. In interviews, executives whose boards scored higher than their peers on this performance measurement related how they work with their boards in such areas as recruitment of new members, financial management, fundraising, and leadership development.  相似文献

Research examining impacts of teenage childbearing on economic and social outcomes have focused on completed schooling and labor force outcomes. In this paper, we examine outcomes that have remained largely unexplored, soft skills and personality. We use Add Health data to construct relevant controls for teenage mothers and explore a set of measures that proxy for what is usually deemed in economics as “non-cognitive” or “soft skill” traits. We find that teenage childbearing increases impulsivity, a trait that has been found to have negative effects on a large set of outcomes and has a negative effect on other personality traits perceived as positive, such as openness to experiences. Our results remain consistent through a set of robustness checks, and we interpret our findings to suggest that adolescence may be a sensitive period for the development of soft skills and that childbearing may interrupt this process.  相似文献

In this commentary, I consider what can go wrong in research when tensions arise between methodology and procedural ethics. I recount difficulties negotiating and implementing a participant recruitment strategy during my doctoral research project, which aimed to explore the experiences of people affected by dementia in the United Kingdom who were disengaged from services. To access this hard-to-reach population, I intended to adopt an informal recruitment strategy, snowball sampling from personal contacts and striking up conversations in public places. The procedural ethics committee were unhappy with this approach, deeming it potentially coercive. They suggested a more formal recruitment strategy enacted via emailing community organisations and churches. This approach entailed practical consequences that ultimately weakened the study sample, data and findings. This case raises questions about the negotiation of tensions between methodology and procedural ethics in gerontological research.  相似文献

Though language manifests linearly, one word at a time, children must learn that words are embedded in constituents, which are in turn embedded in larger constituents. That is, they must learn that syntax is hierarchically structured. Prosody—speech melody and rhythm—is likewise hierarchically organized, with smaller prosodic constituents embedded in larger ones. This paper presents results showing that 20‐month‐olds (= 40) can use modifier + clause prosody to learn constituents at multiple levels in a hierarchically structured artificial grammar, but that they fail to learn from clause + modifier prosody. We consider several explanations for this asymmetry, and suggest that it may be due to the frequency of the two constructions in the input. Two parallel experiments with adults suggest that older learners may not be able to learn the prosodically marked constituents. Instead, adult responses are likely based on perceptually prominent boundary words.  相似文献

This paper uses national longitudinal data and several new empirical strategies to examine the consequences of teenage fatherhood. The key contribution is to compare economic outcomes of young fathers to young men whose partners experienced a miscarriage rather than a live birth. The results suggest that teenage fatherhood decreases years of schooling and the likelihood of receiving a high school diploma and increases general educational development receipt. Teenage fatherhood also appears to increase early marriage and cohabitation, and has mixed short-term effects on several labor market outcomes.  相似文献

In this paper, we use a longitudinal survey that has collected information for 50 years on a large cohort of Wisconsin high school graduates and their siblings to examine the long term impact of early occupational choice on health status. We find evidence that beginning a career in a blue collar occupation is correlated with several measures of poor health outcomes at ages 50–65. Since our dataset includes usually unobserved pre-labor market characteristics, including IQ and childhood health status, we can show that controlling for these variables is important for many results and suggests a high level of selection into occupation based on health and ability. We also provide evidence of gender differentials in the association between first occupation and later health. Then, we replace our basic measure of occupational categories with summary measures of job characteristics and find that employment at “bad jobs” at the beginning of an individual’s career predicts later health outcomes. Finally, we use sibling information in the dataset to show that unmeasured family background factors explain a large share of the effects of occupation on later health. Overall, the evidence points to limited, though heterogeneous, long term effects of health from blue collar employment.  相似文献

This article deconstructs the “illegal–legal” binary that characterizes much immigration scholarship. Using in‐depth interviews with 42 1.5‐generation Brazilian immigrants in young adulthood, I find that respondents discuss a distinct hierarchy with four categories of legal membership—undocumented, liminal legality, lawful permanent resident (LPR), and citizen—that affect their daily lives and incorporation. Liminally legal and LPR statuses in particular challenge this illegal–legal dichotomy. Liminal legality is an “in‐between” status in which immigrants possess social security numbers and work permits but have no guarantee of eventual citizenship. Without opportunities to regularize their status, both undocumented and liminally legal young adults face increased vulnerabilities to poverty and social exclusion. Liminally legal youth, however, are in better positions than their undocumented peers during early adulthood because of state‐delimited rights associated with their legal status.  相似文献
