An effective step-down algorithm for the construction and the identification of nonisomorphic orthogonal arrays

In this paper we present an effective algorithm for the construction and the identification of two-level nonisomorphic orthogonal arrays. Using this algorithm, we identify and list a full catalogue of nonisomorphic orthogonal arrays with parameters OA(24,7,2,t), OA(28,6,2,t) and OA(32,6,2,t), t ≥ 2. Some statistical properties of these designs are also considered.     

18-run nonisomorphic three level orthogonal arrays

In this paper we construct all possible orthogonal arrays OA(18,q, 3,2) with 18 runs and 3 ≤ q ≤ 7 columns and present those that are nonisomorphic. A discussion on the novelty and the superiority of many of the designs found in terms of isomorphism and generalized minimum aberration has been made.      

"仁"学价值的"同构性"与"异质性"

孔子的"仁者,人也"思想,为儒学的发展奠定了基本价值旨向。由血缘所形成的家庭是个人走向社会的过渡环节,家庭既有社会性的因素又有个人的形成内容,因此便具有外部社会和内在个体的双重特点。而基于家庭与社会所具有的"同构性"使得由个人所形成的内在道德品质不但在以血缘为基础的家庭中起着重要的作用,而且更为复杂和扩大的社会视域中具有同样的作用;另一方面,个人与社会所具有的"异质性",使得在儒家道德伦理体系中,存在着固有的矛盾即"修己"与"安人";"内圣"与"外王"之间的矛盾。     

我国高技术产业同构性与集聚的实证分析

本文利用产业分工指数和产业的区位熵,实证分析了我国东、中、西部以及11个省／市高技术产业的结构差异性与产业的地方专业化问题。分析结果表明,从1995-2002年总体上我国高技术产业的同构性是减弱的,产业的地方专业化更加明显,显然这两种结论是互为印证的,并与当前有关高技术产业同构性趋强的观点是不一致的。本文还提出了未来我国各地区高技术产业的发展思路。     

Coercive,normative and mimetic isomorphism as determinants of the voluntary assurance of sustainability reports

This study offers an opportunity to understand how country- and industry-specific effects may affect the decision to assure sustainability reports by identifying institutional pressures. Based on neo-institutional theory, the aim of this research is to highlight whether assurance derives from the coercive, normative and mimetic forces related to legal and cultural strength and the industry pressure for assurance, respectively. The panel data analysis of an international sample of 696 companies for the period 2007–2014 shows that voluntary assurance acts as a legitimization tool implemented by companies in response to normative, coercive and mimetic pressures; that is, companies operating in countries that have a greater legal system and cultural development, especially in industries that are greatly concerned about sustainability, are more likely to issue an assurance statement. Moreover, through a two-stage logit model, we respond to the question of which is the relevant institutional factor that causes voluntary assurance to be adopted. Specifically, we evidence that the normative factor is the one that exerts the greatest explanatory power in the assurance demand, followed by coercive pressure.     

Born to be similar? Global isomorphism and the emergence of latecomer business schools

By building on insights from institutional isomorphism, this paper investigates the development paths of latecomer business schools in Hong Kong, (South) Korea, Singapore, and Taiwan. The global isomorphic pressure prevalent in higher education (e.g. the global regime of rankings) drives latecomers to imitate the practices of incumbents in order to enhance their academic impact through business and management research. Our study argues that latecomers respond to global isomorphism by forging their own paths. Our analysis shows that business knowledge production in Hong Kong and Singapore was more responsive to coercive (research strategy) and normative (faculty recruitment strategy) isomorphic pressure than Korea and Taiwan. The response to mimetic isomorphic pressure (co-authorship strategy) was less salient in Hong Kong and Taiwan than in Singapore and Korea. Further, we find that research, faculty recruitment, and co-authorship strategies affect the academic impact (citations) of the higher education institutions across each country differently. Our study sheds new light on the role of global isomorphism in the emergence of latecomer business schools.     

Framing the first-price auction

We revisit the result that, in laboratory independent private values auction, the first-price sealed bid and descending clock (or Dutch) implementations are not isomorphic. We investigate the hypothesis that this arises from framing and presentation effects. Our design focuses on a careful construction of subject interfaces that present the two environments as similarly as possible. Our sessions also consist of more auction periods to test whether any initial framing effects subsequently decrease over time. We find the difference between the implementations persists. To further investigate the difference, we report on an intermediate implementation which operates like the Dutch auction, but in which the clock continues to tick to the lowest price without informing bidders when others have bid on the object.

EVALUATING THE IMPACT OF LEGAL CHANGE ON NON-PROFIT AND FOR-PROFIT ORGANIZATIONS - The case of the Israeli longterm care insurance law

This article evaluates the impact of legal change on non-profit and for-profit organizations providing home care services mandated in the Israeli Long-Term Care Insurance Law, through the lens of neo-institutional and resource dependency theories. The findings of the study, which was conducted over a ten-year period, revealed that the distinctions between organizations in the two sectors are blurring due to coercive, mimetic, and normative isomorphism. Considerable dependence on government funding provided for in the law forces these organizations to adopt behavior that conforms to government policies and standards for service provision. Moreover, the growing tendency toward mimetic behavior and the increasing proportion of professional workers in both sectors causes for-profit and non-profit organizations to adopt similar bureaucratic behavior and organizational structures.     

Understanding the adoption of socially responsible supplier development practices using institutional theory: Dairy supply chains in India

Supplier development (SD) initiatives play an important role in building buyer-supplier capacities to deal with social and economic performance. The aim of this paper is to explain the motivations behind the adoption of similar SD strategies to address sustainability (particularly social issues) occurring in local supply chains of a developing country. We compare the economic and social variants of institutional theory to investigate whether efficiency or legitimacy seeking drives the adoption (and copying) of SD practices. Twelve case studies involving private and cooperative dairies were conducted in India via semi-structured interviews. Findings revealed that both private and cooperative dairies adopt similar SD practices to build supplier capabilities and improve social and economic performance of buyers and suppliers. Private dairies imitate SD practices of the cooperatives to survive the competition; i.e., economic performance is the main reason behind their isomorphism. Cooperatives, on the other hand, take up SD practices more for legitimacy and even philanthropic reasons; though also partly note the long-term economic benefits from developing the supplier community. These findings can be used both by practitioners and researchers to gain valuable insights into the reasons driving organisational isomorphism in social sustainability practices from a developing country perspective, something rarely done so far in the literature.
