Abstract

Purpose

The purpose of this study is to highlight that in today’s polarised information environment, freedom of speech should not be conflated with a freedom to spread demonstrable lies unchallenged. The authors argue for a review of information literacy instruction to focus on social justice and help participants understand the implications of the views they may hold on vulnerable minority groups.

Design/methodology/approach

In this paper, the authors review and reflect upon the delivery of staff development training on the facts and myths surrounding transgender issues. The authors also encourage other library and information professionals to expand their information literacy instruction into polarised issues that are marked by considerable amounts of misinformation.

Findings

Training participants reported that being more aware of transphobic media coverage will help them reduce bias and better support trans students and staff. It also enabled further opportunities for colleagues across teams and a variety of roles to incorporate the principles of equality, diversity and inclusion into their practice. The success of the sessions also contributed to wider institutional change.

Originality/value

Trans people are a vulnerable minority facing severe, persistent harassment and discrimination both in everyday life and potentially in educational settings. Offering staff effective tools to educate themselves about media transphobia is a step towards creating an environment where trans students and staff can flourish. The authors explore how the media coverage of trans issues allows misinformation to stick and spread. Through applying the concepts of critical thinking and information literacy to trans issues, the authors explain how unconscious bias towards the trans community can be challenged.

Abstract

The depth and breadth of the market for contingent claims, including exotic options, has expanded dramatically. Regulators have expressed concern regarding the risks of exotics to the financial system, due to the difficulty of hedging these instruments. Recent literature focuses on the difficulties in hedging exotic options, e.g., liquidity risk and other violations of the standard Black‐Scholes model. This article provides insight into hedging problems associated with exotic options: 1) hedging in discrete versus continuous time, 2) transaction costs, 3) stochastic volatility, and 4) non‐constant correlation. The author applies simulation analysis of these problems to a variety of exotics, including Asian options, barrier options, look‐back options, and quanto options.

Abstract

The development of web information systems has led to new challenges regarding the scalability and expressiveness of methods. In particular, as systems become large, it becomes decisive to guarantee consistency and integrity of designs. The paper introduces the challenges in a step‐by‐step way and indicates how to cope with them. First, the conceptual model of a WIS as a collection of media types, i.e. extended views, is introduced. In this context the adaptivity to users, channels and devices will also be discussed. Secondly, WIS development is discussed on a higher level of abstraction dealing with tasks, roles, user profiles and storyboards. At this level equational reasoning can be applied. Finally, both levels of abstraction are combined leading to further challenges by using dynamic and deontic logics.

Abstract

This chapter adopts the midrange theories schema to expand Pels and Sheth (2017) matrix on business models to serve the low-income consumers (LIC): market adaptation, mission focus, radical innovation, and inclusive ecosystems. To this end, it identifies the underlying general business theories (systems theory and neo-classical economics) and ontological theories (positivism and interpretivist) nested in each of the matrix’s four cells.

Understanding the general theories from which concepts and guidelines are drawn allows a two-way contribution. On one hand, it comprehends which other concepts can be integrated into the LIC literature. Alternatively, it highlights what insights generated from the study of the LIC markets bring to these theories.

Abstract

Purpose

This paper aims to analyze and give directions for advancing research in stock market volatility highlighting its features, structural breaks and emerging developments. This study offers a platform to research the benchmark studies to know the research gap and give directions for extending future research.

Design/methodology/approach

The author has performed the literature review, and, reference checking as per the snowballing approach. Firstly, the author has started with outlining and simplifying the significance of the subject area, the review illustrating the various elements along with the research gaps and emphasizing the finding.

Findings

This work summarizes the studies covering the volatility, its properties and structural breaks on various aspects such as techniques applied, subareas and the markets. From the review’s analysis, no study has clarified the supremacy of any model because of the different market conditions, nature of data and methodological aspects. The outcome of this research work has delivered further magnitude to research the benchmark studies for the upcoming work on stock market volatility. This paper has also proposed the hybrid volatility models combining artificial intelligence with econometric techniques to detect noise, sudden changes and chaotic information easily.

Abstract

Purpose

The conceptual framework developed in the present study aims to highlight the importance of human resource (HR) practices as a mediator between national culture and employees' careers.

Design/methodology/approach

The approach taken is a literature review and the development of a conceptual model.

Findings

The paper contributes to the literature by focusing on how culture via HR practices might influence career success. Drawing on Hofstede's cultural dimensions, five propositions are developed regarding the impact of culture on career‐relevant HR practices, and how these practices are likely to influence employee career success.

Research limitations/implications

Culture's effect should not be overstated. Looking at the propositions, it is possible that the influence of HR practices on career success is more pronounced than the direct effects of culture on career success. Future work is needed to measure and compare the relative strength of different associations as well as the possibility that other HR dimensions relevant to the study of career success may exist.

Originality/value

At a general level, there is ample evidence of the impact of culture on the effectiveness of a variety of individual outcomes. The paper focused on the mediating role of HR practices as opposed to advancing hypotheses about direct relationships between culture and career success.

Abstract

Purpose

The purpose of this paper is to use filtered extreme‐value theory (EVT) model to forecast one of the main emerging market stock returns and compare the predictive performance of this model with other conditional volatility models.

Design/methodology/approach

This paper employs eight filtered EVT models created with conditional quantile to estimate value‐at‐risk (VaR) for the Istanbul Stock Exchange. The performances of the filtered EVT models are compared to those of generalized autoregressive conditional heteroskedasticity (GARCH), GARCH with student‐t distribution, GARCH with skewed student‐t distribution, and FIGARCH by using alternative back‐testing algorithms, namely, Kupiec test, Christoffersen test, Lopez test, Diebold and Mariano test, root mean squared error (RMSE), and h‐step ahead forecasting RMSE.

Findings

The results indicate that filtered EVT performs better in terms of capturing fat‐tails in stock returns than parametric VaR models. An increase in the conditional quantile decreases h‐step ahead number of exceptions and this shows that filtered EVT with higher conditional quantile such as 40 days should be used for forward looking forecasting.

Originality/value

The research results show that emerging market stock return should be forecasted with filtered EVT and conditional quantile days lag length should also be estimated based on forecasting performance.

Abstract

Purpose

This paper aims to investigate the effect of factors that inhibit adoption of mobile payments service in India.

Design/methodology/approach

Based on the extant literature on mobile payment service and other related literature, factors were identified that drive consumer resistance toward its adoption. It engaged “innovation resistance theory” framework for understanding consumer resistance. The framework addressed five categories of barriers, namely, usage, value, risk, image and tradition that lead to negative perception of innovation, and therefore, induces positive impact on its resistance. Additionally, the study considered a few lesser investigated barriers (habitual use of cash, surveillance, technology) for the study, thus extending the existing theoretical framework. Hypotheses were framed, field data were collected and then analyzed using multivariate techniques.

Findings

Few interesting observations were made from the study. Usage, image and value barriers hindered adoption of mobile payment service. In case of men, usage, value and image were the primary barriers. For women, usage, image, habitual use of cash and technology acted as barriers that curbed mobile payments service adoption. Additionally, except risk, tradition and surveillance barriers, relationships of all other constructs with adoption intention were moderated by gender.

Research limitations/implications

This research was limited to the views of the urban population in India who used mobile payments service. The results may vary across geographical contexts because of culture or socioeconomic differences.

Practical implications

The growth of mobile payment service has remained sluggish in India despite high levels of digitization. The study results will offer valuable insights to the Indian business managers and policymakers to identify what action plan needs to be instituted to make mobile payments service more attractive and acceptable to users.

Originality/value

This empirical study extended and tested the classical innovation resistance theory framework by adding three less studied barriers (surveillance, habitual use of cash and technology) in a developing nation, thus enriching the current literature on consumer resistance toward mobile payments. It also examined the moderating effect of gender on mobile payments service adoption.

Abstract

Purpose

The purpose of this paper is to emphasize green building concept usage and its effect on operating costs and uses Grha Prodia, a building with a green concept owned by PT. Prodia Widyahusada.

Design/methodology/approach

This research will test whether Grha Prodia could earn Leadership in Energy and Environmental Design (LEED) certification based on the aspects that it has and it will also compare the operating costs of Grha Prodia with Prodia Tower. The two main theories used in this research are cost and green building.

Findings

The result of this research is Grha Prodia is considered as a green building and it could earn LEED certification if the current aspects are continuously implemented and maintained.

Originality/value

Moreover, it can fulfill all prerequisite credits in each criterion and further enhance it by fulfilling optional credits in all criteria available. Grha Prodia is also able to demonstrate lower operating costs than a regular building, with 63 percent less water usage and 53 percent less electricity usage.

Abstract

Purpose

The purpose of this paper is to focus on ecological consumption and test the effect of social value orientation on ecological consumption. What is more, this paper explores how Chinese consumers choose between prosocial and non-prosocial products under the influence of Chinese face culture.

Design/methodology/approach

The authors assume that social value orientation will change individual’s ecological consumption through the in-group identification, and simultaneously predict that the influence in pro-self and pro-social consumer groups will vary. Furthermore, Chinese face consciousness will moderate the relationship between ecological consumption and social value orientation. Online research and intercept survey are employed to collect data. In total, 600 questionnaires were distributed.

Findings

The results indicate that pro-social individuals prefer sustainable consumption than pro-self-individuals, and in-group identification mediates the effect of social value orientation on ecological consumption. Interestingly, pro-self-individuals’ behaviors have changed dramatically by the influence of face consciousness.

Originality/value

The authors discovered that social value orientation has a deep impact on ecological consumption through in-group identification. The authors tested and verified the dominance of Chinese face culture. Besides, four key elements of China’s “face” construct are proposed, namely, holism, synergy, synchronicity and dynamics, which enlarge the horizon of the theory of face.
