Using longitudinal data from North Carolina that contains detailed identifiers, we estimate the effect of having a National Board for Professional Teaching Standards (NBPTS) teacher on academic achievement. We identify the effects of an NBPTS teacher exploiting multiple sources of variation including traditional‐lagged achievement models, twin‐ and sibling‐fixed effects, and aggregate grade‐level variation. Our preferred estimates show that students taught by National Board certified teachers have higher math and reading scores by 0.04 and 0.01 of a standard deviation. We find that an NBPTS math teacher increases the present value of students' lifetime income by $48,000. (JEL I20, I21, J2444)  相似文献

Using eight two-year panels from the Medical Expenditure Panel Survey data for the period 2004 to 2012, we examine the effect of economic shocks on mental health spending by families with children. Estimating two-part expenditure models within the correlated random effects framework, we find that employment shocks have a greater impact on mental health spending than do income or health insurance shocks. Our estimates reveal that employment gains are associated with a lower likelihood of family mental health services utilization. By contrast employment losses are positively related to an increase in total family mental health. We do not detect a link between economic shocks and mental health spending on behalf of fathers.

The goal of this study is to provide a cross-lagged examination of the relationships between engaging leadership, job resources and employee work engagement. We propose a mediation model and we postulate that engaging leadership can increase perceptions of three specific job resources (i.e. autonomy, support from colleagues and opportunities for learning and development) which theoretically correspond to the three facets of engaging leadership (i.e., inspiring, connecting and strengthening, respectively). Subsequently, in keeping with the extant body of Job Demands-Resources (JD-R) research, we link job resources to employee work engagement. Our hypotheses were tested on data collected at two time-points – T1 (N = 759) and T2 (N = 273) –from employees working for a hotel chain in the Netherlands. In line with our expectations, engaging leadership showed a significant cross-lagged relationship with autonomy and support from colleagues, but did not predict learning opportunities and work engagement across time. While we formulated specific hypotheses, we also tested reversed causation relationships. We found no direct effect from engaging leadership on employee work engagement, however, the reversed effect was significant; employee perceptions of engaging leadership were shaped by their own engagement experiences. Importantly, engaged employees at T1 reported more job resources at T2. By providing a cross-lagged examination of our model, we showed that engaging leaders as well as employees’ positive affective state of being engaged, are essential to shaping a resourceful work context. A comprehensive view on the triggers and outcomes of work engagement and engaging leadership is needed, as the traditional unidirectional cause-effect rationale fails to explain how these concepts relate to one another and to employee experiences of job resources.  相似文献

This paper discusses the relationship between corporate volunteering and civic engagement outside the workplace in Russia, proceeding from a mixed-method approach. The quantitative findings are based on a comparison between employees in 37 Russian companies who participated in corporate volunteering (N = 399) and those who did not (N = 402). Using binary logistic regression analysis, we demonstrate that employee participation in corporate volunteering is positively related to four forms of civic engagement outside the workplace: informal volunteering, formal volunteering, formal monetary donation, and informal monetary donation. In addition, we draw on information obtained from interviews with 10 corporate volunteers, as well as with all 37 company corporate volunteering managers, to develop a general explanation for why corporate volunteering might lead to civic engagement. We identify three primary explanations. First, trust in companies can be converted into increased trust in social institutions. Second, corporate volunteering can expose employees to other realities, thereby leading them to rethink their priorities. Third, corporate volunteering socializes employees to volunteering, thus making them more likely to incorporate volunteering into their personal repertoires of activities. Corporate volunteering appears to be an effective mechanism for stimulating civic engagement and volunteering infrastructure in post-communist countries.  相似文献

Most research on line design assumes that human operators perform independently from the status of the line. Recent empirical evidence is contradictory. Humans are likely to change their working speed if they might otherwise cause idle time (Schultz et al., Manage Sci 44(12):1595–1607, 1998). This peculiarity of worker behavior is observed in a variety of settings but little is still known about optimal line design that accounts for this more realistic modeling of worker behavior. Therefore, we analyze work allocation in a serial line with limited buffer capacity and adaptive human behavior. An extensive simulation study reveals that optimal work allocation in state-dependent models is different from classical state-independent models. A bowl-shaped work allocation might be suboptimal and design guidelines are more complicated. Depending on the extent of human reactions, a bowl-shaped, balanced, or reversed-bowl work allocation can be preferable.  相似文献

This article analyzes a paradoxical feature in post-Soviet Russian literature and film, where an anti-imperial message coexists with colonial tropes. It focuses on two short stories: “Slabye kosti” (“Weak Bones,” 1988) by Liudmila Petrushevskaia and “Kavkazskii plennyi” (“Prisoner of the Caucasus,” 1995) by Vladimir Makanin. Set respectively in Central Asia and the Caucasus, these stories reflect on the troubled Russian and Soviet relationship with these regions. Despite their artistic complexity and anti-imperial messages, these works are trapped by the literary tropes and cultural stereotypes of the past. These stories relate to a broader cultural trend characteristic of post-Soviet Russian culture. On the one hand, Russian culture has remained unreceptive to post-colonial discourses adopted by Western intellectuals. On the other hand, the resurgence of imperial preoccupations in contemporary Russia, as well as the anxiety surrounding Russia’s territorial integrity, preclude the development of Russia’s own discourses on ethnically distinct peripheries and identities. As a result of this discursive silence, even nuanced writers, such as Makanin and Petrushevskaia, rely on the traditional models of representing the Caucasus and Central Asia.  相似文献
