Disparate Levels of Stress in Police and Correctional Officers: Preliminary Evidence from a Pilot Study on Domestic Violence

New data from a prevention curriculum project on officer-involved domestic violence reveals significant differences in the reported job stress of Florida's correctional officers when compared to police officers who took the same surveys. The significantly higher reported levels of organizational stress in particular—especially those related to staff and resource shortages and attitudes about leadership—raise concerns about the relationship between organizational stress and the reported drastic budget cuts, hiring freezes, and layoffs experienced by the Department of Corrections in 2009. The surprising disparity has significant implications for policy makers, who should be aware of the high cost of stress in officer health and well-being when making budgetary decisions about the state's rapidly increasing inmate population.     

Genealogies and Gene-ideologies: The Legitimacy of the Beta Israel (Falasha)

The migration of the vast majority of Beta Israel (Falasha) to Israel has been accompanied by major shifts in the discourse regarding their ‘Jewishness’ and ‘Ethiopian-ness’. This article discusses the adoption of traditions of Danite descent in place of traditions of Solomonic descent and the emergence of genetics as the most important identity marker, replacing reckonings of lineage. The first shift is connected to the migration of the Beta Israel from Ethiopia to Israel; the second to changing concepts of what represents ‘proof’ of identity in the modern and post-modern world.

The Design and Introduction of Product Lines When Consumer Valuations are Uncertain

This article presents a model of the design and introduction of a product line when the firm is uncertain about consumer valuations for the products. We find that product line introduction strategy depends on this uncertainty. Specifically, under low levels of uncertainty the firm introduces both models during the first period; under higher levels of uncertainty, the firm prefers sequential introduction and delays design of the second product until the second period. Under intermediate levels of uncertainty the firm's first product should be of lower quality than one produced by a myopic firm that does not take product line effects into consideration. We find that when the firm introduces a product sequentially, the strategy might depend on realized demand. For example, if realized demand is high, the firm's second product should be a higher‐end model; if demand turns out to be low, the firm's second product should be a lower‐end model or replace the first product with a lower‐end model.     

对共轭梯度法中标量β_k的一种修正

共轭梯度法是优化算法中最常用的方法之一,适于解决大规模问题,因而有着广泛的应用,而标量kβ不同的选取可以构成不同的共轭梯度法。修正了共轭梯度法中的标量kβ,将其推广到一般情况,并在wolfe线搜索下证明了它的全局收敛性。     

论钟嵘对刘桢的评价

刘桢是建安七子之一,钟嵘的《诗品》把诗人分为上中下三品,刘桢被列在上品,而且排在王粲之前。这一评价大异于前后的曹丕、曹植、沈约、刘勰、萧纲等人,显示出极其个人化的评价。就钟嵘而言,如此看重刘桢,与他对《国风》一脉的尊崇,对五言诗的重视,对风骨、气等关学风格的偏向有关。因为刘桢源于《国风》,五言诗写得尤好,且诗歌慷慨多气。不过钟嵘将刘桢排在建安之首的看法并没有被后来的文学史所采纳。这主要是因为风骨只是魏晋南北朝时期特别标举的风格,后来人并不以之为诗歌最重要的评价标准。再者,将刘桢视作建安之首,只是钟嵘一家之言。由于刘勰在文论史上的崇高地位,他视王粲为七子之首,更决定了文学史的看法。     

在总结经验中建设党

在中国共产党90年来的历史上,先后发生过两次系统的纠正“左”倾错误的运动,它们提供了极其深刻的历史教训。90年来党的发展,最本质的内容就是运用马克思主义的立场、观点和方法,研究问题,解决问题,推进中国的民族解放、社会解放和现代化事业。当前,党最重要的任务是把中国建设成为一个高度民主、高度法治、高度繁荣、高度和谐、高度稳定的现代化国家,需要以开放的心态,以世界性的眼光去总结一切有用的经验。建设现代法治国家,坚持现代化过程中的科学发展,正确应对国际形势的挑战,关系全面建设小康社会的全局。而建设一个成熟的民主型的现代政党,坚持实事求是、求真务实的思想路线,坚持党内民主制度的建设,坚持党的群众路线,则是目前阶段的重要问题。
