Abstract

Purpose

The purpose of this paper is to research how corporate communication regarding a specific corporate event (i.e. Tesla’s tweets about a new product) as well as the framing of both the event itself and the market reactions therewith in the news media influence the formation of the share price of the respective company over time. In so doing, the study provides insights into the nature of market-moving information and the role of financial news flows in shaping market reactions in today’s high-frequency news and information environment.

Design/methodology/approach

Using a multi-method case study approach, combining quantitative intraday event studies with a qualitative text analysis of financial online news and tweets by Elon Musk and Twitter, the authors shed light on the complex interaction between market events, financial information and stock market reactions. The analysis covers a period of four days, encompassing the announcement and introduction of the new battery pack for Model S and X by Tesla as well as the accompanying and follow-up reporting by the financial news media.

Findings

Findings show that market reactions are driven by business events and expectations among the market rather than the follow-up reporting by financial news media. Financial online news instead seems to heavily rely on Elon Musk’s attention-triggering news to sustain its 24-h airtime with a variety of reporting tools, keeping the highly demanded audience engaged. Eventually, Twitter accounts of media visible companies and personalities, such as Tesla and its CEO Elon Musk, have been found to be useful market information sources for day traders and shareholders to trade at a profit.

Originality/value

The study is a response to recent discussions about the legitimacy of Twitter communication by CEOs or representatives of listed companies. The findings show that Twitter communication needs to be well considered in light of strict market regulations (e.g. SEC in the USA) regarding insider-trading and the publication of market-relevant information. In addition, corporate financial communication should avoid impetuous communication via social media channels as this could have deterrent effects on the market valuation of a listed company.

Abstract

Purpose – Police violence involving minority citizens is a significant problem in the United States. Efforts to explain the disparate treatment of minorities have often relied on structural-level racial threat hypotheses. However, research framed by this macro-level approach fails to consider meso-level characteristics of spatially specified places within cities. The place hypothesis maintains that police see disadvantaged minority neighborhoods as especially threatening and, therefore, use more violence in them. Reconceptualizing the racial threat model to include meso-level characteristics of place is essential to better explain police violence.

Design/methodology/approach – The argument is investigated using literature drawn from quantitative analyses of structural predictors of police violence and qualitative/quantitative studies of the police subculture and police behavior within disadvantaged neighborhoods.

Findings – Research on the effects of city-level racial segregation on police violence supports the place hypothesis that the incidence of police violence is higher in segregated minority neighborhoods. City-level segregation is, however, only a proxy for the degree of concentrated minority disadvantage existing at the meso-level. Community-level studies suggest that the police do see disadvantaged places as especially threatening and use more violence in them. Plausibly, meso-level neighborhood characteristics of cities may prove to be better predictors of the incidence of police violence than are structural-level characteristics in cross-city comparisons.

Originality/value – This analysis builds on structural-level racial threat theories by demonstrating that meso-level characteristics of cities are central to explaining disparities in the use of police violence. A multilevel approach to studying police violence using this analytic framework is proposed.

Abstract

The objective of this study is to investigate how country risk, different political actions from the government and bureaucratic behavior influence the activities in industry supply chains (SCs) in emerging markets. The main objective of this study is to investigate the influence of these external stakeholders’ elements to the demand-side and supply-side drivers and barriers for improving competitiveness of Ready-Made Garment (RMG) industry in the way of analyzing supply chain. Considering the phenomenon of recent change in the RMG business environment and the competitiveness issues this study uses the principles of stakeholder and resource dependence theory and aims to find out some factors which influence to make an efficient supply chain for improving competitiveness. The RMG industry of Bangladesh is the case application of this study. Following a positivist paradigm, this study adopts a two phase sequential mixed-method research design consisting of qualitative and quantitative approaches. A tentative research model is developed first based on extensive literature review. Qualitative field study is then carried out to fine tune the initial research model. Findings from the qualitative method are also used to develop measures and instruments for the next phase of quantitative method. A survey is carried out with sample of top and middle level executives of different garment companies of Dhaka city in Bangladesh and the collected quantitative data are analyzed by partial least square-based structural equation modeling. The findings support eight hypotheses. From the analysis the external stakeholders’ elements like bureaucratic behavior and country risk have significant influence to the barriers. From the internal stakeholders’ point of view the manufacturers’ and buyers’ drivers have significant influence on the competitiveness. Therefore, stakeholders need to take proper action to reduce the barriers and increase the drivers, as the drivers have positive influence to improve competitiveness.

This study has both theoretical and practical contributions. This study represents an important contribution to the theory by integrating two theoretical perceptions to identify factors of the RMG industry’s SC that affect the competitiveness of the RMG industry. This research study contributes to the understanding of both external and internal stakeholders of national and international perspectives in the RMG (textile and clothing) business. It combines the insights of stakeholder and resource dependence theories along with the concept of the SC in improving effectiveness. In a practical sense, this study certainly contributes to the Bangladeshi RMG industry. In accordance with the desire of the RMG manufacturers, the research has shown that some influential constructs of the RMG industry’s SC affect the competitiveness of the RMG industry. The outcome of the study is useful for various stakeholders of the Bangladeshi RMG industry sector ranging from the government to various private organizations. The applications of this study are extendable through further adaptation in other industries and various geographic contexts.

Abstract

Purpose

The purpose of this paper is to mitigate the dearth in the library literature of large‐class, active learning pedagogies, by providing examples of these instructional approaches used in mega‐classes within the science, humanities, and education fields, for application within the library environment, specifically in large information literacy instruction sessions.

Design/methodology/approach

The author surveys both the library and science and education literatures, comparing coverage of active learning approaches in the professional literatures of each.

Findings

Although the library literature enthusiastically supports active learning approaches to teaching information literacy in theory, there are statistically few librarians who employ these learning modalities in their teaching. There are hardly any examples in the library literature of librarians using large‐class, active‐learning pedagogies. This article discusses some of the reasons behind librarians' reluctance to use active learning techniques and offers pragmatic suggestions from the literature of the sciences and education to alleviate this reticence.

Originality/value

This paper helps fill in the gap in the library literature discussing large‐class, active pedagogies for information literacy instruction. It offers some practical solutions from within the non‐library literature to some of the pedagogical obstacles inherent in mass classes, making explicit applications to information literacy instruction.

Abstract

The study of humor has a long tradition in philosophy, sociology, psychology, anthropology, and communications. Evidence from these fields suggests that humor can have effects on creativity, cohesiveness, and performance, but organizational scholars have paid it relatively little attention. We hope to “jump-start” such a research program. To do this, we first outline the theoretical rationale underlying the production and appreciation of humor, namely, its motivational, cognitive, and emotional mechanisms. Next, we review the literature linking humor to creativity, cohesiveness, and other performance-relevant outcomes. In particular, we note how this literature is theoretically well-grounded, but that the empirical findings are largely correlational and/or based on qualitative research designs. Finally, we go beyond the current humor literature by developing specific predictions about how culture might interact with humor in organizational contexts. Throughout the paper, we discuss possible research directions and methodological issues relevant to the study of humor in organizations.

Abstract

For over three decades, vector autoregressions have played a central role in empirical macroeconomics. These models are general, can capture sophisticated dynamic behavior, and can be extended to include features such as structural instability, time-varying parameters, dynamic factors, threshold-crossing behavior, and discrete outcomes. Building upon growing evidence that the assumption of linearity may be undesirable in modeling certain macroeconomic relationships, this article seeks to add to recent advances in VAR modeling by proposing a nonparametric dynamic model for multivariate time series. In this model, the problems of modeling and estimation are approached from a hierarchical Bayesian perspective. The article considers the issues of identification, estimation, and model comparison, enabling nonparametric VAR (or NPVAR) models to be fit efficiently by Markov chain Monte Carlo (MCMC) algorithms and compared to parametric and semiparametric alternatives by marginal likelihoods and Bayes factors. Among other benefits, the methodology allows for a more careful study of structural instability while guarding against the possibility of unaccounted nonlinearity in otherwise stable economic relationships. Extensions of the proposed nonparametric model to settings with heteroskedasticity and other important modeling features are also considered. The techniques are employed to study the postwar U.S. economy, confirming the presence of distinct volatility regimes and supporting the contention that certain nonlinear relationships in the data can remain undetected by standard models.
