The high turnover of congressional staff members can have a negative effect on the functioning of Congress as an institution. Though junior staff turnover is not considered a significant concern, the high turnover of senior staff members is problematic. Using data from a survey of staff members located in the Washington personal offices of House of Representatives members, this article investigates what factors influence the likelihood to leave congressional employment. Specifically, I explore how solidary, purposive, and material work incentives influence staff members’ plans to exit. The results of two different models—one for junior and mid-level staff members and one for executive staff members—indicate that purposive incentives, and material incentives that accrue for future employment opportunities, carry the most weight across both models. Current salary has a significant effect on executive staff members, but not on their lower-level counterparts. Following this analysis, I propose actions that congressional offices might take to retain staff.  相似文献

Live-in child domestic workers in Bangladesh often experience the surveilling power of their employer's gaze as a Foucauldian panopticon, which both disciplines and engages children in forms of self-discipline. I argue that female child domestic workers in particular have a form of ‘thin’ agency whereby they are severely restricted in their abilities to make independent decisions or to act to their own benefit. I ethnographically unpack the concept of thin agency by analyzing material, cultural, spatial and discursive constraints that both employers and female child domestic workers engage in their daily lives.  相似文献

The degradation of archaeological wood at freezing and thawing temperatures is studied at the site of Qajaa in West Greenland through a combination of environmental monitoring, measurement of oxygen consumption and microscopy of wood samples. Permanently frozen wood is still very well preserved after 2–4000 years, while wood samples that thaw every summer show attack by soft rot and an average density loss of 0.1 g cm–3 (corresponding to 25% of the dry mass) over the past 27 years. Future increases in temperature may increase the decay rate significantly (Q10 = 4.2 at 0–10°C) but the effects on site depend on local hydrology.  相似文献

Abstract. Business cycles in different regions of the United States tend to synchronize. This study investigates the reasons behind this synchronization of business cycles and the consequent formation of a national business cycle. Trade between regions may not be strong enough for one region to “drive” business cycle fluctuations in another region. This study suggests that regional business cycles synchronize due to a nonlinear “mode‐locking” process in which weakly coupled oscillating systems (regions) tend to synchronize. There is no definitive test for mode‐lock. However, simulations, correlations, Granger causality tests, tests for nonlinearities, vector autoregressions, and spectral analysis reveal modest econometric support for the regional mode‐locking hypothesis of business cycle synchronization.  相似文献

Arsenic has previously been measured in a bone sample of a c. 5-year-old Mesolithic child from Nivaagaard in Denmark yielding an anomalously high value of 13 μg/g. In the present work we show that other individuals at a nearby site also exhibit elevated arsenic levels, whereas individuals from other Mesolithic sites in Denmark are found to have quite low As-concentrations. Several attempts to reveal the source of the arsenic are reported: A railway track near the site, where the railway sleepers were suspected to have been impregnated with As leading to transport or diffusion of As into the adjacent soil; Several food items, the remains of which were found at the site, and one food item not preserved in the excavation, i.e. seaweed. Finally, it is shown that the most likely explanation of the elevated arsenic levels in human bones at Nivaa is diagenesis.  相似文献
