High‐Performance Work Systems in Professional Service Firms: Examining the Practices‐Resources‐Uses‐Performance Linkage

Professional service firms (PSFs) play an important role in the knowledge‐based economy. Their success is highly dependent on their people, the knowledge resources they possess, and how they use these resources. However, how to systematically manage human resources to attain high performance is not fully understood. This study addresses this issue by investigating the linkage mechanisms through which high‐performance work systems (HPWS) influence the performance of PSFs. We integrate resource‐based and dynamic capability theories in order to identify and investigate two intervening mechanisms that link HR practices to firm performance. The first mechanism is the intellectual capital resources comprising the human, social, and organizational capital that HPWS create. The second mechanism is the uses to which both HPWS and resources can be applied, operationalized as organizational ambidexterity, the simultaneous exploitation of existing knowledge and exploration of new knowledge. These mechanisms are hypothesized to link HPWS to firm performance in the form of a practices‐resources‐uses‐performance linkage model. Results from a longitudinal study of 93 accounting firms support this linkage model. © 2015 Wiley Periodicals, Inc.     

Career Management in High‐Performing Organizations: A Set‐Theoretic Approach

The aim of this study is to investigate the elements of organizational career management (OCM) that can lead to strong organizational performance. The growing unpredictability of careers requires a different organizational approach of careers. Yet, new career models all focus on the individual as the central actor, leaving the role of the organization rather underdeveloped. Based on a combined perspective integrating insights from the literature on careers, high performance work systems, and idiosyncratic deals (I‐deals), we address four dimensions of OCM: supportive and developmental practices, development I‐deals, individual responsibility, and consensus. We study their relationships with company performance, thereby including the firm's human capital composition. Surveys were administered to the HR directors of 293 organizations. We apply a relatively new method, fsQCA (fuzzy‐set qualitative comparative analysis), and complement this with more conventional structural equation modeling (SEM). The SEM analyses suggest that only supportive and developmental practices are positively associated with high performance. However, based on the fsQCA, three configurations are identified in which OCM is associated with high performance. The most prevalent configuration combined supportive and developmental practices with I‐deals and individual responsibility for career management. We conclude with a discussion of the implications of our findings, and address the utility of adopting a configurational approach in career research. © 2016 Wiley Periodicals, Inc.     

The High‐Rise Home: Verticality as Practice in London

This article investigates the relationship between verticality and home. It develops the idea of ‘verticality as practice'. This appreciates verticality not as something that takes place in three‐dimensional landscapes, but as the outcome of everyday practical activity. Examining a modernist high‐rise estate, the Aylesbury Estate in London, the article identifies and examines a range of vertical practices, illustrating how they are intertwined with home. Vertical practices, such as those associated with the view, help to make a unique and special home, becoming intensely meaningful to residents. However, they also unmake dimensions of home when they interact with the estate's marginality.

高速铁路对长三角地区消费空间的影响

以长三角地区的南京、苏州、上海和杭州4个城市作为研究对象,通过对城际可达性变化的研究并结合针对旅客的消费问卷调查,分析了城际高速铁路对4个城市不同类型消费空间的影响。引入消费空间场强公式,探讨了城际高速铁路开通前后长三角地区消费空间的重构,即4个城市在长三角区域的消费吸引力变化。结果表明：城际高速铁路对城际文化娱乐、休闲消费空间有较大影响,对实物商品消费空间影响不大;苏州和杭州在区域中的文化娱乐休闲消费场强上升。     

腹腔镜治疗小儿腹股沟疝58例与经腹股沟切口疝囊高位结扎术46例临床效果分析

目的比较腹腔镜疝囊高位结扎术与经腹股沟切口疝囊高位结扎术治疗小儿腹股沟疝的临床效果。方法回顾性分析我院收治的腹股沟疝患儿104例的临床资料,其中行腹腔镜疝囊高位结扎术患儿58例作为腹腔镜组,行传统经腹股沟切口疝囊高位结扎术患儿46例作为对照组,比较两组平均手术时间、术后疼痛持续时间、住院时间及并发症发生情况。结果腹腔镜组平均手术时间、术后疼痛持续时间和住院时间分别为(19.2±2.2)min,(22.6±4.5)h和(3.0±0.6)d;对照组分别为(42.5±4.2)min,(56.2±6.0)h和(5.8±1.1)d,两组比较差异均有统计学意义(P<0.05)。腹腔镜组出现阴囊水肿2例,无皮下血肿和鞘膜积液发生;对照组出现阴囊水肿5例,皮下血肿3例,继发鞘膜积液2例,腹腔镜组并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论腹腔镜疝囊高位结扎术微创、手术和住院时间短、并发症少,是治疗小儿腹股沟疝的理想术式。
