The author develops and extends the asymptotic F- and t-test theory in linear regression models where the regressors could be deterministic trends, unit-root processes, near-unit-root processes, among others. The author considers both the exogenous case where the regressors and the regression error are independent and the endogenous case where they are correlated. In the former case, the author designs a new set of basis functions that are invariant to the parameter estimation uncertainty and uses them to construct a new series long-run variance estimator. The author shows that the F-test version of the Wald statistic and the t-statistic are asymptotically F and t distributed, respectively. In the latter case, the author shows that the asymptotic F and t theory is still possible, but one has to develop it in a pseudo-frequency domain. The F and t approximations are more accurate than the more commonly used chi-squared and normal approximations. The resulting F and t tests are also easy to implement – they can be implemented in exactly the same way as the F and t tests in a classical normal linear regression.

Law enforcement agents enforce rules that they might transgress in their private lives. Building from a theory of “hypocrisy aversion” where agents incur psychological costs from imposing a sanction on others for rules that they might break, the authors design a two-player game in which players are simultaneously placed in the roles of enforcer and potential transgressor. In this model, discretionary enforcement is endogenous to the size of the sanction. Conditional on rewards to enforcement and punishment that are both sufficiently small in the status quo, the authors demonstrate that price effects can be dominated by second-order hypocrisy effects, leading to rates of transgression that increase with larger sanctions. The authors test the model within a laboratory experiment where individuals can simultaneously gamble at the expense of a third party and punish those they observe gambling. Examining the comparable testable predictions of models of (i) selfish agents, (ii) pro-social agents, and (iii) pro-social agents who are averse to hypocrisy, the authors find evidence of hypocrisy aversion in the rates of gambling, sanctioning, and the changing composition of agent strategies. Our results suggest that increasing sanctions can backfire in the deterrence of common criminal and non-criminal offenses.

Given the increasing global focus of many aspects of our society, researchers have taken significant steps in understanding the impact of culture on various psychological states. This review focuses on the stressor–strain relationships within the context of cross-cultural and cross-national studies. Using research findings from the United States as a baseline, we identify common and unique themes concerning the stressor–strain relationships between different countries, and clarify the differences between cross-national and cross-cultural studies. Furthermore, we consider cross-cultural and cross-national occupational stress research from an individual differences perspective. We encourage future studies to adopt this perspective and carefully consider the implications of cultural values on occupational stress research at the individual, group, and country levels.

This chapter provides a comprehensive review of research and developments relating to the use of Web 2.0 technologies in education. As opposed to early educational uses of the Internet involving publication of static information on web pages, Web 2.0 tools offer a host of opportunities for educators to provide more interactive, collaborative, and creative online learning experiences for students. The chapter starts by defining Web 2.0 tools in terms of their ability to facilitate online creation, editing, and sharing of web content. A typology of Web 2.0 technologies is presented to illustrate the wide variety of tools at teachers’ disposal. Educational uses of Web 2.0 technologies such as wikis, blogs, and microblogging are explored, in order to showcase the variety of designs that can be utilized. Based on a review of the research literature the educational benefits of using Web 2.0 technologies are outlined, including their ability to facilitate communication, collaborative knowledge building, student-centered activity, and vicarious learning. Similarly, issues surrounding the use of Web 2.0 tools are distilled from the literature and discussed, such as the possibility of technical problems, collaboration difficulties, and plagiarism. Two case studies involving the use Web 2.0 tools to support personalized learning and small group collaboration are detailed to exemplify design possibilities in greater detail. Finally, design recommendations for learning and teaching using Web 2.0 are presented, again based on findings from the research literature.

Tokenization is a relatively new activity in digital finance. Tokenization, a process that creates a blockchain representation of the underlying instrument, can enhance the standard features and characteristics of assets and securities. Asset and security tokenization produces many benefits. These benefits include reducing issuance and trading costs, lessening dependency on intermediaries, facilitating more liquidity in markets, and providing greater transparency around an asset’s lifecycle for all parties involved. This chapter synthesizes the key characteristics, benefits, processes, tools, and techniques of tokenizing real-world assets. It also provides several examples of current asset-backed token applications to help understand the rapidly growing industry and analyzes future expectations of this new technology.

In this chapter, the authors consider the relationships between institutional settlements at the field level and the instantiation of logics at the organizational level. The authors present the case of Supervised Consumption Sites (also known as Safe Injection Sites) in Alberta, Canada where a settlement of logics supported by one government was disrupted with the election of a new provincial government in 2015, and then disrupted again after the election of yet another government four years later. The authors use this case to show how different institutional settlements can support or threaten particular types of organizations, and they also show how the instantiation of different settlements in organizations (organizational hybridity) can impact the ways in which organizations present themselves. By analyzing the public justifications provided by key members of Supervised Consumption Sites, they draw attention to connections between institutional settlements at the field level and organizational attempts to manage multiple logics.

This chapter examines the existence of dynamic herding behavior by Tunisian investors in the Tunisia stock market during the revolution period of 2011–2013. The sample covers all Tunindex daily returns as a proxy for the Tunisia stock exchange index over the period 2007–2018. The author modifies the cross-sectional absolute deviation model to include all market conditions (bull and bear markets) and the geopolitical crisis effect corresponding to the Tunisian Jasmine revolution during 2011–2013, and show that herding is indeed not present in the Tunisia stock market including during its turmoil periods. These findings imply that the Tunisian emerging financial market became more vulnerable to adverse herding behavior after the revolution. There is also a clear implication for capitalist firms and angel investors in Tunisia that adverse herding behavior tends to exist on days of higher uncertainty and information asymmetry.

Budget hotels are becoming an emerging industry for convenience and affordability, where consumer sentiments are of paramount importance. Tourism has become increasingly dependent on social media and online platforms to gather travel-related information, purchase travel products, food, lodging, etc., and share views and experiences. The user-generated data helps companies make informed decisions through predictive and behavioural analytics.

Design/Methodology/Approach: This study uses text mining, deep learning, and machine learning techniques for data collection and sentiment analysis based on 117,151 online reviews of the customers posted on the TripAdvisor website from May 2004 to May 2019 from 197 hotels of five prominent budget hotel groups spread across India using Feedforward Neural Network along with Keras package and Softmax activation function.

Findings: The word-of-mouth turns into electronic word-of-mouth through social networking sites, with easy access to information that enables customers to pick a budget hotel. We identified 20 widely used words that most customers use in their reviews, which can help managers optimise operational efficiency by boosting consumer acceptability, satisfaction, positive experiences, and overcoming negative consumer perceptions.

Practical Implications: The analysis of the review patterns is based on real-time data, which is helpful to understand the customer’s requirements, particularly for budget hotels.

Originality/Value: We analysed TripAdvisor reviews posted over the last 16 years, excluding the Corona period due to industry crises. The findings reverberate in consonance with the performance improvement theory, which states feed-forward a neural network enhances organisational, process, and individual-level performance in the hospitality industry based on customer reviews.

Data visualizations in some form or another have served as decision-support tools for many centuries. In conjunction with advancements in information technology, data visualizations have become more accessible and more efficient to generate. In fact, virtually all enterprise resource planning and human resource (HR) information system vendors offer off-the-shelf data visualizations as part of decision-support dashboards as well as stand-alone images and displays for reporting. Plus, advances in programing languages and software such as Tableau, Microsoft Power BI, R, and Python have expanded the possibilities of fully customized graphics. Despite the proliferation of data visualization, relatively little is known about how to design data visualizations for displaying different types of HR data to different user groups, for different purposes, and with the overarching goal of improving the ways in which users comprehend and interpret data visualizations for decision-making purposes. To understand the state of science and practice as they relate to HR data visualizations and data visualizations in general, we review the literature on data visualizations across disciplines and offer an organizing framework that emphasizes the roles data visualization characteristics (e.g., display type, features), user characteristics (e.g., experience, individual differences), tasks, and objectives (e.g., compare values) play in user comprehension, interpretation, and decision-making. Finally, we close by proposing future directions for science and practice.

The people of Taiwan are no strangers to natural disasters; the island sits astride the junction point of the Philippine and Eurasian tectonic plates, making it a frequent victim of sometimes calamitous earthquakes. The island also lies in the path of yearly typhoons that buffet the island, risking life and property damage. These natural disasters have become a fact of life for the Taiwanese people, and the population has long looked to the government for leadership in ensuring disaster preparation, relief, and recovery. This chapter is focused on the leadership qualities exhibited by public administrators in the field of emergency management in Taiwan, and how they navigate the uncharted waters of this new field in a traditional culture. Beginning with a general examination of the cultural and societal influences on the position of leader in Taiwan society and the qualities demanded of that position, the research narrows to the specific field of emergency management and how administration in this realm is accomplished given (a) the relative newness of the field itself and (b) the cultural barriers in Taiwan to the widespread embrace of such disaster mitigation initiatives. The struggle of Taiwan public administrators to adopt disaster preparedness programs in the nation presents itself as a unique opportunity to examine how leaders in such situations walk the razor’s edge between doing what is necessary to ensure that the population have access to the advantages of the modern world while respecting the cultural sensitivities that can often stand in the way of administrative progress.
