Abstract
We provide a new characterization of the equality of two positive-definite matrices A and B, and we use this to propose several new computationally convenient statistical tests for the equality of two unknown positive-definite matrices. Our primary focus is on testing the information matrix equality (e.g. White, 1982, 1994). We characterize the asymptotic behavior of our new trace-determinant information matrix test statistics under the null and the alternative and investigate their finite-sample performance for a variety of models: linear regression, exponential duration, probit, and Tobit. The parametric bootstrap suggested by Horowitz (1994) delivers critical values that provide admirable level behavior, even in samples as small as n = 50. Our new tests often have better power than the parametric-bootstrap version of the traditional IMT; when they do not, they nevertheless perform respectably.

Abstract
Although Korean sociology of sport is relatively unknown to the international community of scholars, it is a mature field in Korea. Sociology of sport was first introduced in Korea in the mid-1960s when the field first evolved in North America and Europe. However, the development of the field shows different aspects from its Western counterpart due to unique cultural and environmental factors both in academia and in society. There are three major research trends that form Korean sociology of sport. First, there is the research focus on the benefit of sport and physical activity by examining empirical data using quantitative methodologies. The second group of researchers pays attention to individual experience in diverse sport fields and utilize qualitative methodologies to investigate empirical or secondary data. The third and most recent trend is a critical approach that theoretically analyzes ideologies, power relations, and identity politics in sport and society. When looking at the future, there are problems and limitations within the field in Korea. These include lack of continuity in terms of conference sub-themes, over-production of doctoral degree graduates, conservatism rooted in the field, and a danger of regarding sport policy research as an exit for sport sociologists. However, there are also possibilities and reasons for optimism. The biggest possibility for Korean sociology of sport is globalization of the field. Another significant possibility is the need for sport sociologists in planning, developing, and evaluating sport policy. Finally, diversification of the field gives ample opportunities for future research.

Abstract
While the origin of Korean Industrial Relations goes back 150 years when the country opened its seaports to foreign countries, it didn’t emerge as a field of study until 1950s when academics began to write books and papers on the Korean labor movement, labor laws, and labor economics. In this paper, we sketch this history and describe important events and people that contributed to the development of industrial relations in Korea. Korean industrial relations in the early 20th century were significantly distorted by the 35-year-Japanese colonial rule (1910–1945). After regaining its independence, the U.S. backed, growth-oriented, military-based, authoritarian Korean government followed suit and consistently suppressed organized labor until 1987. Finally, the 1987 Great Labor Offensive allowed the labor movement to flourish in a democratized society. Three groups were especially influential in the field of industrial relations in the early 1960s: labor activists, religious leaders, and university faculty. Since then, numerous scholars have published books and papers on Korean industrial relations, whose perspectives, goals, and processes are still being debated and argued. The Korean Industrial Relations Association (KIRA) was formed on March 25, 1990 and many other academic and practitioner associations have also come into being since then. The future of industrial relations as a field of study in Korea does not seem bright, however. Issues regarding organized labor are losing attention because of a steadily shrinking unionization rate, changing societal attitude toward labor unions, and the enactment of new and improved laws and regulations regarding employment relationships more broadly. Thus, we suggest that emerging issues such as contingent workers, works councils and tripartite partnership, conflict management, and human rights will be addressed by the field of industrial relations in Korea only if this field breaks with its traditional focus on union and union–management relations.

Abstract
The current era of the fourth industrial revolution has attracted significant research on the use of digital technologies in improving construction project delivery. However, less emphasis has been placed on how these digital tools will influence the management of the construction workforce. To this end, using a review of existing works, this chapter explores the fourth industrial revolution and its associated technologies that can positively impact the management of the construction workforce when implemented. Also, the possible challenges that might truncate the successful deployment of digital technologies for effective workforce management were explored. The chapter submitted that implementing workforce management-specific digital platforms and other digital technologies designed for project delivery can aid effective workforce management within construction organisations. Technologies such as cloud computing, the Internet of Things, big data analytics, robotics and automation, and artificial intelligence, among others, offer significant benefits to the effective workforce management of construction organisations. However, several challenges, such as resistance to change due to fear of job loss, cost of investment in digital tools, organisational structure and culture, must be carefully considered as they might affect the successful use of digital tools and by extension, impact the success of workforce management in the organisations.

Abstract
Understanding institutional distance – i.e., the difference in institutional context between countries – is critical for firms whose operations span national boundaries. Institutional distance impacts the relative attractiveness of country markets, trade-offs among foreign market entry strategies, the management of subsidiaries abroad, and ultimately, firm performance. Although scholars in various disciplines have made great advances in defining and measuring the institutional characteristics of nations, we contend that many of these advances have occurred in a parallel fashion. Moreover, extant empirical studies focus disproportionately on the impact of different subsets of the identified institutional characteristics. We suggest that it is time to find common ground across the disparate literatures. Doing so would allow us to view differences in institutional contexts more holistically, and refine our understanding of their implications for multinational corporations.

Abstract
In this chapter, we examine the multifaceted challenges that feminist labor organizations face in decommodifying the lives and labor of poor and working-class women. Using an in-depth case study of domestic worker organizing in South Korea, we find that non-governmental organizations (NGOs) such as the National House Managers Cooperative and the Korean Women Workers Association became entangled in hegemonic state projects that linked support for women’s basic livelihoods to the proliferation of part-time, informal domestic work in the context of widespread crises. To challenge the discriminatory and market-driven logics of state-driven social protection efforts, these NGOs have advanced an emancipatory agenda to improve the working conditions, labor rights, and social dignity of domestic workers through consciousness-raising grassroots organizing methods and contentious policy advocacy campaigns. Their social movement transformation goals, however, have been constrained by the relative organizational isolation and limited organizational capacity of feminist labor NGOs in a broader context of neoliberal precaritization and gender-stratified labor markets. The myriad dilemmas facing domestic worker organizing in an era of global hegemonic market rule highlight the need to develop new political imaginaries to contest gender and economic injustice.
