GMM Estimation with persistent panel data: an application to production functions

This paper considers the estimation of Cobb-Douglas production functions using panel data covering a large sample of companies observed for a small number of time periods. GMM estimatorshave been found to produce large finite-sample biases when using the standard first-differenced estimator. These biases can be dramatically reduced by exploiting reasonable stationarity restrictions on the initial conditions process. Using data for a panel of R&Dperforming US manufacturing companies we find that the additional instruments used in our extended GMM estimator yield much more reasonable parameter estimates.     

Performance management practices in lean manufacturing organizations: a systematic review of research evidence

This paper provides the first systematic look into the existing research on performance management (PM) practices employed in lean manufacturing organisations (LMOs). It adopts a systematic review method to examine the evidence generated in the period 2004 – 2015 and uses a comprehensive PM framework to synthesise the findings. The results suggest that PM practices that have the most prominent role in LMOs are those that, firstly, are located closest to front-line actions and, secondly, explicitly address operational realities. This calls into question the primacy of accounting-driven controls in LMOs, suggesting that operational controls may be more effective than top-down accounting-based PM practices. The results also confirm the bias towards operational-level issues but suggest that LMOs may integrate the operational and the strategic levels by using PM practices that drive organisational learning through employee involvement and engagement.     

National culture and organisational culture in lean organisations: a systematic review

Despite the extensive literature suggesting that culture plays a key role in lean implementations, no previous review has focused on the topic. This study is a systematic review of the literature that synthesises over two decades of publications according to the levels of national culture (NC) and organisational culture (OC) and maps which cultural dimensions foster or hinder lean implementation. In terms of NC, this study shows that Japanese cultural traits might hinder lean, such as masculinity and power distance, hence avoiding the over simplification that lean is a country-specific management approach. In terms of OC, the literature review unveils a lack of consensus and underlines two paradoxes, namely the co-existence of both process and result-focused orientations and both normative and pragmatic approaches. This review ultimately offers a relevant agenda for lean research as well as a guide for managers who face the challenge of implementing and sustaining lean in their organisations.     

需求分布规律变化情况下的报童订货策略

在需求分布规律变化情况下,报童在进行订货决策时会因为错误判断需求分布规律而导致期望库存成本增加。为了解决这一问题,本文集成传统历史需求信息和非传统需求信息以正确地认知需求分布规律,在此基础上决策订货量。假设需求服从均值不同、方差相同的两种类型的正态分布,每一种正态分布的概率已知。利用信号检测理论构建基于历史需求信息与需求分布概率的报童最优订货策略,并与只基于需求分布概率的直觉规则订货策略进行对比。结果表明：只要排除需求分布概率很大或很小两种极端情况,最优订货策略比直觉规则订货策略在控制期望库存成本方面的作用更明显,即利用历史需求信息可以有效修正报童对实际需求分布的检测结果,从而提高实际订货决策的准确性。研究结果对传统历史需求信息和非传统需求信息的集成以及需求信息交换等有一定的管理学启示和应用价值。     

On artistic and cultural generations in Northeastern Tibet

Beginning in the 1980s, and continuing for over three decades since, a particular generation of Tibetans from the Northeastern Tibetan region known as Amdo, and particularly from the northern parts of China’s Qinghai province, has proven extremely productive. Why has this generation, born primarily between 1959 and 1967, been so incredibly successful? This article examines the contextual factors that may have contributed to the incredible success of this generation. This ranges from the policies and circumstances that affected their births, and the state of the cultural field at the time they reached adulthood. Personal experience narratives, autobiographies, and scholarly studies then reveal how this generation was able to access the intellectual field. Finally, I briefly discuss how the Amdo Tibetan intellectual field compares with other Tibetan and ethnic experiences in the People’s Republic of China.     

The sexual in Chinese sociology: homosexuality studies in contemporary China

Through a meta‐literature review, this paper examines the changing contours of Chinese sociology of homosexuality in contemporary China. It unfolds the different theoretical orientations and methodologies that construct the modern male homosexual subject under major socio‐economic and political changes. Chinese sociology of homosexuality started in the reform era and has been dominated by Western knowledge production and the political ideology of the communist party‐state. Fused with the bio‐medical model and the state's modernization project in the 1980s–1990s, the sociological study adopted a functionalist and positivistic approach with survey‐based methodology in the main which focused on the etiology of homosexuality. A new transnational knowledge production of sociology of homosexuality has formed since the 2000s which has shifted towards a constructivist/ post‐structuralist approach and reflexive qualitative methodology. The new sociological study examines the rise of male (as well as female) homosexual identity in China, questions the hetero/homosexual binary and discusses how an individual makes sense of homosexual identity to form same‐sex intimate relationships. By tracing the epistemology of homosexuality in contemporary China, this paper rethinks the dominance of the Western construction and the role of the state in shaping the knowledge of homosexuality and proposes alternative spaces for theorizing Chinese sexual identities, desires and practices.     

100 key research questions for the post‐2015 development agenda

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations.     

荷兰集成农业对我国现代农业发展的启示

我国在发展现代农业、推进社会主义新农村建设的过程中,将会长期受到现代农业生产技术特别是有机农业生产技术推行成本高、风险大的制约.荷兰通过把复杂的现代农业生产管理技术集成到农业装备中,然后把集成技术装备植入现代农业生产的各环节,很好地解决了先进农业技术推行成本高、风险大的问题.长期以来,荷兰用这种集成技术装备的办法发展园艺业、奶牛业等复杂农业,取得了世界农业强国的地位,这是很值得我国发展现代农业借鉴的.
