The purpose of this paper is to examine the value-at-risk and related measures for the Bitcoin and to compare the findings with Standard and Poor’s SP500 Index, and the gold spot price time series.

A GJR-GARCH model has been implemented, in which the residuals follow the standardized Pearson type-IV distribution. A large variety of value-at-risk measures and backtesting criteria are implemented.

Bitcoin is a highly volatile currency violating the value-at-risk measures more than the other assets. With respect to the Basel Committee on Banking Supervision Accords, a Bitcoin investor is subjected to higher capital requirements and capital allocation ratio.

The risk of an investor holding Bitcoins is measured and quantified via the regulatory framework practices.

This paper is the first comprehensive approach to the risk properties of Bitcoin.

To examine the strategic posture of third‐party logistics (3PLs) providers in mainland China.

A sample survey, obtained by mail, of 3PLs firms in mainland China. Key informant data are used to operationalize Porter's competitive strategy and provides a framework to identify logistics strategies pursued by 3PLs providers. Various aspects of 3PLs providers are compared by different strategy types.

Identified four logistics strategies pursued by 3PLs providers in mainland China. Differentiation strategy outperforms cost leadership strategy. Companies pursuing cost leadership are shifting towards differentiation strategy to cope with the intense competition faced in mainland China's immense logistics markets.

Bias may exist due to the mail survey. In‐depth studies on strategy formulation of 3PLs providers could be carried out to examine what factors influence the strategy formulation and explore the strategy evolution path.

This study is a very insightful source of information about 3PLs in mainland China for logistics managers, investors and policy‐makers. It provides guidance for 3PLs executives to formulate logistics strategy, adjust business objectives and prioritize operations, and for logistics users to select appropriate logistics providers. There are also suggestions for government to improve the business environment for the logistics industry. The study provides a basis for research on logistics management in mainland China.

This study is a pioneer and comprehensive study of mainland China's 3PLs providers. To the best of our knowledge, this is the first study to examine 3PLs providers in mainland China.

This paper aims to explore the ambiguity and limitations of measuring firm-level multinationality (FLM) using theoretical and empirical comparisons of existing methods. The paper puts forward a list of five key aspects that collectively serve as a tool for researchers to select the most appropriate method for future research and as a basis for the future development of methods.

Firstly, the author reviews existing methods of measuring FLM and consolidates findings into five key aspects. Secondly, the author uses the aspects to compare existing methods theoretically, and subsequently, the author groups them into three distinct streams. Thirdly, the author compares existing methods across a sample of the 35 largest European MNEs by sales in 2020 to identify and demonstrate the ambiguity and limitations of these methods.

The author identifies the five key aspects of measuring FLM: framework, aggregation, segmentation, metrics and indicators. Using empirical comparison, the author empirically confirms the limitations highlighted in the literature and shows the differences and inconsistencies among methods, which cause confusion rather than clarity in the extant literature. Additionally, the author emphasises that three distinct streams further drive the debate on the regional/global nature and present further limitations of methods not mentioned in the literature to date.

This paper provides the most comprehensive review of the existing literature on FLM, resulting in five novel aspects of measuring FLM. The analysis of a sample of 35 European firms demonstrates and identifies the ambiguity and limitations of FLM-measuring methods.

Partial least squares structural equation modeling (PLS-SEM) has attracted much attention from both methodological and applied researchers in various disciplines – also in hospitality management research. As PLS-SEM is relatively new compared to other multivariate analysis techniques, there are still numerous open questions and uncertainties in its application. This study aims to address this important issue by offering guidance regarding its use in contexts with which researchers struggle.

The authors examine the most prominent questions and answers posed in a well-known PLS-SEM discussion forum. The authors do so by using a text analysis technique to identify the most salient topics.

The data analysis identifies three salient PLS-SEM topics (i.e. bootstrapping and significance testing, higher-order constructs and moderation).

The results allow us to address the PLS-SEM community’s main methodological issues. The authors discuss each area separately and provide explanations and guidelines.

The guidelines on the most important PLS-SEM topics provide decision-making and application aids. In this way, the authors make a decisive contribution to clarifying ambiguities when applying the PLS-SEM method in hospitality management research and other disciplines.

There has as yet been no systematic analysis of this kind in the field of PLS-SEM; the authors, therefore, present the first research results. The findings and recommendations provide guidance for PLS-SEM applications in hospitality research and practice.

Briefly reviews previous literature by the author before presenting an original 12 step system integration protocol designed to ensure the success of companies or countries in their efforts to develop and market new products. Looks at the issues from different strategic levels such as corporate, international, military and economic. Presents 31 case studies, including the success of Japan in microchips to the failure of Xerox to sell its invention of the Alto personal computer 3 years before Apple: from the success in DNA and Superconductor research to the success of Sunbeam in inventing and marketing food processors: and from the daring invention and production of atomic energy for survival to the successes of sewing machine inventor Howe in co‐operating on patents to compete in markets. Includes 306 questions and answers in order to qualify concepts introduced.

“The unexamined life is not worth living” (Socrates). That is, without critically inquiring into the knowledge of life which is well-being and valuable, life is not worth living. Critical thinking questions existing theories and their unexamined and obsessive assumptions and generalizations, constraints, and “best” practices of the prevailing system of management and tries to replace them with more valid assumptions and generalizations that uphold the dignity, uniqueness, and inalienable rights of the individual person and the community. Better outcomes result from asking the right questions than from having the right answers. In the diverse, pluralist cultural environment of today, the promise of a truly generative dialog among Occidental (Western) and Oriental (Eastern) cultures and civilizations holds great hope for the future. Critical thinking (CT) is an “inclusive” thinking system that can facilitate this dialog such that all of us have a meaningful space and place in this universe. After defining CT and arguing its importance for executives, this chapter introduces CT in two parts: Part 1: Various Approaches to Critical Thinking; Part 2: Major Theories of Critical Thinking. Several contemporary business cases will be invoked to illustrate the need, nature, and scope of corporate CT.

The article's aim is to focus on the application of Six Sigma to minimise intraoperative and post-operative complications rates in a Turkish public hospital cataract surgery unit.

Implementing define-measure-analyse-improve and control (DMAIC) involves process mapping, fishbone diagrams and rigorous data-collection. Failure mode and effect analysis (FMEA), pareto diagrams, control charts and process capability analysis are applied to redress cataract surgery failure root causes.

Inefficient skills of assistant surgeons and technicians, low quality of IOLs used, wrong IOL placement, unsystematic sterilisation of surgery rooms and devices, and the unprioritising network system are found to be the critical drivers of intraoperative-operative and post-operative complications. Sigma level was increased from 2.60 to 3.75 subsequent to extensive training of assistant surgeons, ophthalmologists and technicians, better quality IOLs, systematic sterilisation and air-filtering, and the implementation of a more sophisticated network system.

This article shows that Six Sigma measurement and process improvement can become the impetus for cataract unit staff to rethink their process and reduce malpractices. Measuring, recording and reporting data regularly helps them to continuously monitor their overall process and deliver safer treatments.

This is the first Six Sigma ophthalmology study in Turkey.

Blockchain technology has encouraged more transparent transactions process through decentralized protocols and has identified multi-dimensional benefits. However, value innovation–based blockchain for the particular industry requires further elaboration since there appears to be a vague understanding. Therefore, this study aims to provide a profound perspective of value innovation based blockchain, which has the potential to be applied in the halal industry.

This study developed a typology model that describes a profound understanding of blockchain adoption for value innovation. Empirical research was conducted using multiple case studies to justify the model. The case selection in this study was based on the halal industry in Indonesia. This study employed few sources to derive sufficient data through in-depth interviews, direct observations, and archival records. In particular, this study drew upon specific theories to elaborate on the blockchain-enable value innovation.

A blockchain is identified as having the opportunity to promote value innovation in the halal industry through its features. This study defines a typology model of value innovation-based blockchain for the halal industry that takes place on a particular spectrum. The model built in this study classifies blockchain adoption for the halal industry from specific dimensions: the degree of blockchain-based system complexity and the intensity of value innovation. Then, this study finds that these cases have different classifications and are evenly distributed in the quadrants of the model.

The typology model in this study can be a reference for decision-making when considering blockchain to leverage a value innovation in particular systems. Although blockchain technology can potentially be applied in vast areas, the decision-makers should understand that technology adoption should provide distinct values to its stakeholders, notably in multi-dimensional areas such as the halal industry. Thus, this study contributes significantly to blockchain technology usage for the halal industry.

The management of organizational conflict involves the diagnosis of and intervention in affective and substantive conflicts at the interpersonal, intragroup, and intergroup levels and the styles (strategies) used to handle these conflicts. A diagnosis should indicate whether there is need for an intervention and the type of intervention needed. In general, an intervention is designed (a) to attain and maintain a moderate amount of substantive conflict in nonroutine tasks at various levels, (b) to reduce affective conflict at all levels, and (c) to enable the organizational members to select and use the appropriate styles of handling conflict so that various situations can be effectively dealt with. Organizational learning and effectiveness can be enhanced through an appropriate diagnosis of and process and structural interventions in conflict.

This study aims to examine the relationship between human resource management (HRM) practices and informal workplace learning.

Data were collected from a sample of 381 employees working as heads of the department of branches in private commercial banks of Bangladesh. Hypotheses were tested by using structural equation modelling-partial least square.

Findings of the study revealed that HRM practices such as selective hiring, extensive training, performance appraisal, compensation practices, empowerment and information-sharing, significantly positively related with informal workplace learning.

Based on the situated learning and organizational support theory, this study is empirically testing how HRM practices influence informal workplace learning.
