The purpose of this paper is to examine how instructional leadership, a concept imported from Western scholarship, has been conceptualized in the Taiwanese context and how principal instructional leadership is realized in schools. The development trajectory of principal instructional leadership is delineated by examining empirical studies in the past two decades.

This paper adopts an exploratory approach to review the Taiwanese empirical literature on principal instructional leadership. A total of 80 studies were systematically analyzed and common themes were identified.

This paper finds that a hybrid model of the conceptualization of instructional leadership has been developed in Taiwan. Principals performed more indirect than direct leadership behaviors. A gap exists between the ideal instructional leader and the reality.

The development of a formal theory of instructional leadership is expected as various substantive theories are developed and more data are accumulated. To yield the desired outcome of knowledge acceleration, the coordination of research efforts across scholars and institutions is a must.

The articles reviewed suggest less effort spent by principals on the teachers. Yet with a national promotion of teacher learning community, as well as cooperative and collaborative learning in recent years, principal instructional leadership behaviors are expected to rise in terms of ensuring instruction quality and professional development.

This paper is an attempt to accumulate knowledge about principal instructional leadership in Taiwan. It is a contribution to the exploration of indigenous perspectives and practices and the understanding and building of educational leadership in Asia.

Behavioral finance and market microstructure studies suggest that the investor sentiment and liquidity are related. This paper aims to examine the aggregate sentiment–liquidity relationship in emerging markets (EMs) for both the sample period and crisis period. Then, it verifies this relationship, using the asymmetric sentiment.

This study uses a sample consisting of stocks listed on the SSE Shanghai composite index (348 stocks), the JKSE (118 stocks), the IPC (14 stocks), the RTS (12 stocks), the WSE (106 stocks) and FTSE/JSE Africa (76 stocks). This is for the period ranging from February, 2002 until March, 2021 (230 monthly observations). We use the panel data and apply generalized method-of-moments (GMM) of dynamic panel estimators.

The empirical analysis shows the following results: first, it demonstrates a significant relationship between the aggregate investor sentiment and the stock market liquidity for the sample period and crisis one. Second, referring to the asymmetric sentiment, we have empirically given proof that the market is significantly more liquid in times of the optimistic sentiment than it is in times of the pessimistic sentiment. Third, using panel causality tests, we document a unidirectional causality between the investor sentiment and liquidity in a direct manner through the noise traders and the irrational market makers and also a bidirectional causality in an indirect channel.

The results reported in this paper have implications for regulators and investors in EMs. Firstly, the study informs the regulators that the increases and decreases in the stock market liquidity are related to the investor sentiment, not financial shocks. We empirically evince that the traded value is higher in the crisis. Secondly, we inform insider traders and rational market makers that the persistence of increases in the trading activity in both quiet and turbulent times is associated with investor participants such as noise traders and irrational market makers.

The originality of this work lies in employing the asymmetric sentiment (optimistic/pessimistic) in order to denote the sentiment–liquidity relationship in EMs for the sample period and the 2007–2008 subprime crisis.

The purpose of this paper is to investigate whether or not the presence of female directors at the time of an initial public offering (IPO) can be considered as a signal of IPO quality.

A sample of 220 Malaysian IPOs over the period of 2005–2015 was used. This study employed the mean regression technique (ordinary least squares and White’s heteroskedasticity-consistent standard errors) and the median regression technique (quantile regression) to examine the signalling power of female directors on the board at the time of an IPO.

The results show that the presence and proportion of female directors at the time of the IPO have negative effects on IPO initial returns (IR). The negative effects occur at both the conditional mean and the dispersion of IPO IR. These results are robust to endogeneity bias.

The findings of this study suggest that female directors on the board at the time of an IPO can be considered as a desirable signal of IPO quality. As a result, IPO issuers can consider signalling the quality of their IPOs by having female directors on their boards. Likewise, market participants can use female directors as an instrument to value an IPO.

Studies on the impact of female directors on the board have largely been centred on established companies. Thus, this study contributes to the literature by examining the signalling role of women at the time of an IPO, which is considered as a significant milestone in the lifecycle of a company.

The purpose of this paper is to analyze the impact of macroeconomic‐industrial and bank‐specific factors on Latin American banks’ performance.

Using the data panel system estimator version of the generalized method of moments, the authors estimate the determinants of return on assets and interest margin for a sample of 78 commercial banks from Argentina, Brazil, Chile, Colombia, México, Paraguay, Peru, and Venezuela over the period from 1995 to 2010.

On the one hand, the results show that bank performance is positively related to both idiosyncratic factors, such as service diversification, size, capital ratio, and specialization degree, and to macroeconomic‐industrial factors such as economic growth, inflation, and bank concentration. On the other hand, the results show that bank performance is negatively related to credit risk, liquidity risk, and operational inefficiencies.

The authors provide new evidence from the Latin American bank industry and incorporate the effect of diversification through noninterest activities.

Since the outbreak of the COVID-19 pandemic, customers fear for their health when interacting with service providers. To mitigate this fear service providers are using safety signals directed to consumers and other stakeholders who make organizational assessments. The purpose of this article is to synthesize the range of safety signals in a framework that integrates signaling theory with servicescape elements so as to provide guidance for service providers to assist in their recovery.

The authors extracted examples of how service providers signal safety to their consumers that the risk of infection is low in exchanging with their service. These examples were taken from secondary data sources in the form of trade publications resulting from a systematic search and supplemented by an organic search.

In total 53 unique safety signals were identified and assigned to 24 different categories in our framework. Most of the signals fell into the default and sale independent category, followed by the default contingent revenue risking category.

This study builds on signaling theory and service literature to develop a framework of the range of safety signals currently in use by service providers and offers suggestions as to which are likely to be most effective. Further, a future research inquiry of safety signals is presented, which the authors believe has promise in assisting recovery in a post-pandemic world.

The purpose of this study is to explore how the phenomenon of academic professional development looks through the eyes of graduate students navigating the increasing complexity of postgraduate careers. This study pays particular attention to how current students navigate the interplay between their beliefs, intentions and behaviors when it comes to making choices regarding their engagement in professional development.

This is a qualitative study, based on a phenomenological analysis of seven in-depth interviews with advanced PhD students from the earth sciences college at a large, public, research-intensive university located in the mid-Atlantic area of the USA (Penn State).

Framed in the Theory of Planned Behavior, the findings of this study suggest that the interviewees varied across all aspects of Theory of Planned Behavior: in their beliefs about valued career paths, in their convergence or divergence from the departmental or institutional norms they perceived and in their sense of control over their career pathways. They all shared, however, a strong desire to successfully navigate the widening array of possibilities to achieve a range of personal and professional goals, but they often lacked the ability to align those intentions with actions related to professional development.

This study suggests that institutions may wish to rethink their positionality in the professional development of graduate students, moving away from centralized models of direct support and towards more indirect, informal and co-created means of exerting influence and building community.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

This rejoinder aims to critique some of the perspectives in Chen’s (2018) study on hospitality and host–guest paradigm in China.

In this preliminary probe into Chen’s study, critical analysis is performed on Chen’s approaches, whereas document analysis is applied to the relevant ancient Chinese writings. Translations are the author’s own unless indicated otherwise.

Chen’s views are problematic and supported by patchy evidence. “Hierarchy principle” and “host-centric foundation” do not hold up. In a series of asymmetrical comparisons, Chen goes a bit too far in arguing for uniqueness.

This rejoinder presents valid critiques of Chen’s study, thus directing future research in the right direction. It is of some significance to clarify Chen’s misrepresentations and offer a truer and fuller account of Chinese hospitality, given the difficulty for international scholars to validate Chen’s views because of language barrier and cultural unfamiliarity.

The purpose of this study is to determine the proportion of the population that will be susceptible to the COVID-19 pandemic, as well as the proportions of infections, recoveries and fatalities from the COVID-19 pandemic.

The design was a longitudinal survey of COVID-19 infections, recoveries and fatalities in Nigeria using the data on the daily updates of the Nigeria Centre for Disease Control for the period 1 May to 23 August 2020. Markov chain analysis was performed on the data.

The results showed that in the long run, 8.4% of the population will be susceptible to COVID-19 infections, 26.4% of them will be infected, 61.2% of the infected will recover and 4% will become fatal. Thus, if this pattern of infections and recoveries continue, the majority of the infected people in Nigeria will recover whilst a very small proportion of the infected people will die.

A dearth of the extant literature on the problem, especially from the management science perspective.

Results of the study will facilitate policymakers’ response to the curtailment of the pandemic in Nigeria.

Curtailing the pandemic through the results of this study will assist in easing the social consequences of the pandemic.

The proposed adjustment to the susceptibilities, infections and recoveries model through the introduction of a fourth state (fatality) to get the susceptibilities, infections, recoveries and fatalities model, signalling a point of departure from previous studies.
