State of the art in business analytics: themes and collaborations

In this study, we illustrate the most recent stage in the scholarly development of the field of Business Analytics. Using around 23,000 research publications collected from the Web of Science, we network-analyzed four types of dataset that include keywords, titles, institutions, and countries. It is noteworthy that we found a thematic cluster focusing on analytical techniques and tools, particular with the rapid dissemination of “big data”-related studies. It is not surprising that universities and institutions in advanced countries in the West still occupy the central position of the collaboration network. However, we can discern a global shift toward certain developing and transitional economies in the world science base.     

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

How far can brands go to defend themselves? The extent of negative publicity impact on proactive consumer behaviors and brand equity

Negative publicity, defined as the public disclosure of a problematic incident associated with a brand, is a critical issue for fashion brands, as it vitiates the image of targeted brands and drives consumers’ voice and exit behaviors. Despite the impact of negative publicity, few studies have compared the impact of product‐related versus personnel‐related negative publicity, or explored the extent to which brands’ coping strategies can prevent consumers’ anti‐brand behavioral intentions and recover brand equity. This study used multivariate analyses of variance to analyze responses from 594 American consumers, which revealed that when negative publicity is about a product‐related issue, none of the brand's different recovery efforts are effective in decreasing consumers’ voice and exit intentions and protecting brand equity. However, for a personnel‐related issue, functional and informational recovery strategies were effective in decreasing consumer voice and exit intentions, and affective, functional, and informational recovery strategies positively impacted most domains of brand equity (brand judgement, brand feelings, and brand resonance). The following analysis of variance and post hoc analyses revealed the comparative effectiveness of specific recovery types. Discussions and implications of the findings are provided.     

Individualization and Marketization of Responsibility for Gender Equality: The Case of Female Managers in China

This article investigates the question of where the responsibility for promoting gender equality resides in the Chinese employment context. Utilizing Acker's (2006) inequality regimes framework, the study explores women's underrepresentation in management roles in China and explains the persistence of gender inequalities in managerial echelons of Chinese organizations. Based on 30 interviews with female managers, the findings demonstrate the marketization and individualization of gender equality in organizational activity. The existing gender inequality, and the lack of responsibility for tackling it, has been either legitimized by eluding to the commercial‐only focus of organizations or rendered invisible through a belief in individual choice as the determining factor of career progression for women. Gender inequality in management is also maintained through the compliance of female managers themselves with the presumed legitimacy of gender‐based differential access to managerial roles. References to culture and tradition, market forces, competitive pressures, and individual choices by female managers are often made in explaining the unequal career paths and outcomes for men and women in their organizations. Our findings contribute to the human resource management (HRM) literature by framing macrosocietal context as a dynamic and endogenous aspect of management of human resources in organizations and provide novel insights into the interplay between HRM and societal context. © 2016 Wiley Periodicals, Inc.     

Does the Presence of Female Executives Curb Earnings Management? Evidence from Korea

We investigate the role of female executives in curbing earnings management behaviour in Korea, a country known for its strong male‐dominant culture. In a sample of Korean firms from 2002 to 2010, we find that female presence in top management is negatively associated with discretionary accruals, suggesting that gender diversity in senior management deters opportunistic financial reporting even in a highly male‐dominant corporate environment. Further, this association is primarily observed in firms with stronger (weaker) female (male) dominance. This finding is consistent with the idea that female executives can exert more influence on corporate decisions in a more female‐friendly environment. These findings have implications for academics and practitioners seeking to understand the impact of the role of top executive gender diversity in corporate accounting practices.     

Examining futures price changes and volatility on the trading day after a limit‐lock day

This paper examines the effect that price limits have on futures prices by testing what happens to price changes and volatility on the trading day following a limit‐lock day. The results show evidence that prices continue to rise on average the day after an up‐limit day. In addition, limits appear to influence price volatility for some but not all of the futures contracts. However, since the findings vary across the different commodity futures contracts, it is likely that limits do not directly impact price volatility. © 2000 John Wiley & Sons, Inc.

Patterns of technology life cycles: stochastic analysis based on patent citations

Patent analysis has been considered as an effective means of estimating phases of a technology life cycle. However, previous studies have not considered the dynamic and idiosyncratic aspects of a technology’s progression since they were based on deterministic methods, mainly fitting s- or double s-shaped curves to patent application counts. Moreover, previous methods cannot be executed at the individual patent level. We propose a stochastic technology life cycle analysis to trace the phases of a technology’s progression based on patent citations and identify the patterns of technology life cycles at the individual patent level. At the heart of the proposed approach are a hidden Markov model to estimate the probability of a system being at a certain hidden state from observation and cluster analysis to group a set of objects according to their similarities. A case study of patents about laser technology in lithography is presented.     

A generalized penalty function for a class of discrete renewal processes

Analysis of a generalized Gerber–Shiu function is considered in a discrete-time (ordinary) Sparre Andersen renewal risk process with time-dependent claim sizes. The results are then applied to obtain ruin-related quantities under some renewal risk processes assuming specific interclaim distributions such as a discrete K _n distribution and a truncated geometric distribution (i.e. compound binomial process). Furthermore, the discrete delayed renewal risk process is considered and results related to the ordinary process are derived as well.     

Public trust and corruption perception: disaster relief

Public trust in government and nongovernment organizations is essential to the public’s willingness to donate and to support those organizations. We measure public trust in disaster aid using people’s perception of these organizations’ effectiveness in delivering aid relief to the victims of two recent major earthquakes in China. Based on the survey data collected in 2013 from about 2100 residents in Hong Kong, we document the vulnerability of these residents’ trust perceptions in aid delivery. We find that the sharp decline in trust perception is highly negatively correlated with their perception of corruption of local governments in China.     

Knowledge sources and recombination capabilities in developing new convergent products

Recent surge in technological convergences has generated great interests from scholars, managers and policy-makers. Yet, few literatures have investigated firm-specific factors behind developing convergent products. This research has empirically analysed the role of firms’ knowledge recombination capabilities and external collaborations in developing convergent products by using a survey data from 858 Korean firms. The findings suggest that presence of interdisciplinary employees and the strong commitment of CEOs are among the important knowledge recombination capabilities for developing convergent products. When compared to other types of collaboration, the inter-firm collaboration turned out to be the most effective in developing convergent products. We suggest that firms should understand that knowledge generations are becoming more interdisciplinary and employees with interdisciplinary research background are an important enabler of knowledge recombination. We suggest that policy-maker should continue to allocate its resources in supporting inter-disciplinary research programmes.
