Abstract

This study investigates the private equity funds’ performances and persistence by fund type. Diversification benefit exists between public equity and private equity and among different types of private equity funds. The net IRR of private equity funds depends on fund type, economic growth, stock market performance, inflation and interest rate. Fund performance was negatively correlated with capital inflow to private equity market and fund size. Fund size and series are positively correlated. Performance persistency exists in private equity fund managers. Fund type is very important factor in analyzing private equity fund performance and persistency.

Abstract

Purpose

This study aims to explore the effects of expertise diversity on project efficiency and creativity in health-care project teams.

Design/methodology/approach

This study analyzes hierarchical linear models using multi-source data from 50 project teams in a large health-care organization in the USA. This data set includes self-reported survey responses from 274 team members and human resource information for all 515 members across the 50 teams. Expertise diversity is operationalized by professional diversity and positional diversity reflecting two dimensions, domain and level, of the concept of expertise.

Findings

This study reveals that professional diversity is negatively related to project efficiency and project creativity, whereas positional diversity is positively related to project efficiency.

Originality/value

Successfully managing a project team of experts within a limited time frame is a challenge for organizations. This study advances the understanding of the double-edged sword effect of expertise diversity on project teams, focusing on professional and positional diversity. It provides important insights for human resource development in terms of the composition of project teams regarding members’ expertise.

Abstract

Very recently, the South Korean architectural field has seen a rising trend to reinterpret the traditional hanok, meaning Korean-style house. While this presents an interesting diversion from the housing market dominated by high-rise apartments, there is a lack of consensus in determining the scope and definition of hanoks. This is because of many experiments with the features of the hanok, such as inclusion of new material, construction techniques, and even radically new spatial organizations.

This article explores and analyzes the effectiveness of four different approaches of reinterpreting hanoks: apartment hanoks, urban hanoks, rural experimentations, and contemporary versions. At one end of the spectrum, there is the recent integration of a hanok’s features in high-rise apartments otherwise considered modern. Then I move on to discuss examples of urban hanoks built since the start of the industrialization era in the 1920s and afterwards. Urban hanoks are detached houses, most of which show a stylistic preference toward wooden hanoks of the elite literati. The third approach is rural experimentations that involve the development of an unconventional construction method by both architects and non-architects. Finally, this paper turns to reinterpretations of the hanok by architects trained in contemporary architecture. Although each approach differs in the degree of integrating historical hanok features, some commonalities, such as low floor area ratio and the organic integration of an open courtyard, can be detected among the successful cases.

Abstract

There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.

An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).

The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.

In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.

The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

Abstract

Purpose

Understandings of house prices and their interrelationships have undoubtedly drawn a great amount of attention from various market participants. This study aims to investigate the monthly newly-built residential house price indices of seventy Chinese cities during a 10-year period spanning January 2011–December 2020 for understandings of issues related to their interdependence and synchronizations.

Design/methodology/approach

Analysis here is facilitated through network analysis together with topological and hierarchical characterizations of price comovements.

Findings

This study determines eight sectoral groups of cities whose house price indices are directly connected and the price synchronization within each group is higher than that at the national level, although each shows rather idiosyncratic patterns. Degrees of house price comovements are generally lower starting from 2018 at the national level and for the eight sectoral groups. Similarly, this study finds that the synchronization intensity associated with the house price index of each city generally switches to a lower level starting from early 2019.

Originality/value

Results here should be of use to policy design and analysis aiming at housing market evaluations and monitoring.

Abstract

Purpose

Engineering components/structures with geometric discontinuities normally bear complex and variable loads, which lead to a multiaxial and random/variable amplitude stress/strain state. Hence, this study aims how to effectively evaluate the multiaxial random/variable amplitude fatigue life.

Design/methodology/approach

Recent studies on critical plane method under multiaxial random/variable amplitude loading are reviewed, and the computational framework is clearly presented in this paper.

Findings

Some basic concepts and latest achievements in multiaxial random/variable amplitude fatigue analysis are introduced. This review summarizes the research status of four main aspects of multiaxial fatigue under random/variable amplitude loadings, namely multiaxial fatigue criterion, method for critical plane determination, cycle counting method and damage accumulation criterion. Particularly, the latest achievements of multiaxial random/variable amplitude fatigue using critical plane methods are classified and highlighted.

Originality/value

This review attempts to provide references for further research on multiaxial random/variable amplitude fatigue and to promote the development of multiaxial fatigue from experimental research to practical engineering application.

Abstract

Purpose

Traditional Chinese medicine (TCM) prescriptions have always relied on the experience of TCM doctors, and machine learning(ML) provides a technical means for learning these experiences and intelligently assists in prescribing. However, in TCM prescription, there are the main (Jun) herb and the auxiliary (Chen, Zuo and Shi) herb collocations. In a prescription, the types of auxiliary herbs are often more than the main herb and the auxiliary herbs often appear in other prescriptions. This leads to different frequencies of different herbs in prescriptions, namely, imbalanced labels (herbs). As a result, the existing ML algorithms are biased, and it is difficult to predict the main herb with less frequency in the actual prediction and poor performance. In order to solve the impact of this problem, this paper proposes a framework for multi-label traditional Chinese medicine (ML-TCM) based on multi-label resampling.

Design/methodology/approach

In this work, a multi-label learning framework is proposed that adopts and compares the multi-label random resampling (MLROS), multi-label synthesized resampling (MLSMOTE) and multi-label synthesized resampling based on local label imbalance (MLSOL), three multi-label oversampling techniques to rebalance the TCM data.

Findings

The experimental results show that after resampling, the less frequent but important herbs can be predicted more accurately. The MLSOL method is shown to be the best with over 10% improvements on average because it balances the data by considering both features and labels when resampling.

Originality/value

The authors first systematically analyzed the label imbalance problem of different sampling methods in the field of TCM and provide a solution. And through the experimental results analysis, the authors proved the feasibility of this method, which can improve the performance by 10%−30% compared with the state-of-the-art methods.

Abstract

Purpose

Based on an organizational capability perspective, this paper aims to propose a development model for social media analytics (SMA) capability that can be applied to business-to-business (B2B) marketing, with the aim of facilitating the use and integration of SMA in B2B marketing and maximizing the benefits of business networks in the age of social media.

Design/methodology/approach

This is a critical interpretive synthesis of SMA publications collected from academic journals, business magazines and the SMA service industry. In addition, an inter-disciplinary approach was adopted by drawing upon both marketing and information systems literature. In total, 123 academic papers, 106 industry case studies and 141 magazine papers were identified and analyzed. The findings were synthesized and compiled to address the predefined research question.

Findings

An SMA capability development model is proposed. The proposed model consists of four inter-dependent levels (technological, operational, managed and strategic) that collectively transfer the technological capability of SMA to the dynamic organizational capability. Each level of SMA capability is detailed. SMA-in-B2B marketing is highlighted as a socio-technical phenomenon, in which a technological level SMA capability is emphasized as the foundation for developing organizational level SMA capabilities and organizational capabilities, in turn, supporting and managing SMA activities and practices (e.g. strategic planning, social and cultural changes, skills and resources, measurements and values).

Practical implications

The proposed research framework may have implications for the operational level SMA development and the investigations on the direct and/or indirect measurements to help firms see the impact of SMA on their business.

Originality/value

This study may have implications for the adoption, use, integration and management of SMA in B2B marketing. The proposed model is grounded on the integrated insights from academia and industry. It is particularly relevant to B2B firms that have engaged in or plan to engage in applying SMA to extract insights from their online networks and is relevant to B2B researchers who are interested in SMA, big data and information technology organization integration studies.

Abstract

Purpose

The purpose of this study is to emphasize the important role of performance-oriented human resource (HR) practices and gender equality perceptions in supervisors and chief executive officers (CEOs) for career development among women in management.

Design/methodology/approach

This study used a quantitative methodology to examine relationships among variables. The authors conducted a survey to investigate factors influencing the career development of women managers in professional settings, with a sample of 1,502 female managers in South Korea.

Findings

The relationship between performance-oriented HR practices and career development for women managers was supported. In addition, self-leadership significantly mediated the relationship between performance-oriented HR practices and career development. Finally, double moderator effects of gender equality perceptions of CEOs and supervisors on the relationship between performance-oriented HR practices and self-leadership were significant.

Originality/value

This study emphasizes that career development for women in South Korea depends on gender equality awareness and institutional reorganization for best practices at top management levels. Specifically, this study identified the essential role of performance-based HR practices to support self-leadership and career development in women managers. Furthermore, this study recognized gender equality perceptions of CEOs and supervisors as a critical factor in the successful career development of women managers.
