Earnings forecasts of female CEOs: quality and consequences

This study examines the voluntary disclosure of earnings forecasts by female CEOs. We find that in the backdrop of increased pressure to perform from investors and other stakeholders, female CEOs tend to issue more earnings forecasts than male CEOs, and those forecasts are more accurate. We also find that while financial analysts generally prefer to follow companies headed by male CEOs, female CEOs’ efforts to issue accurate earnings forecasts pay off, as these efforts help them close the analyst coverage gap. We provide complementary evidence on the disclosure efforts of female CEOs with regard to updates to the forecast and the 10-K report. Lastly, we show that financial analysts rely more on the earnings forecasts of female CEOs, possibly because they recognize female CEOs’ superior forecasting quality. Our results are robust to the use of alternative research designs, including difference-in-difference, propensity score matching, and entropy balancing. Overall, our study documents gender differences in voluntary disclosure by senior management.

Holocue: A Wearable Holographic Cueing Application for Alleviating Freezing of Gait in Parkinson's Disease

External visual cueing is a well-known means to target freezing of gait (FOG) in Parkinson's disease patients. Holocue is a wearable visual cueing application that allows the HoloLens 1 mixed-reality headset to present on-demand patient-tailored action-relevant 2D and 3D holographic visual cues in free-living environments. The aim of this study involving 24 Parkinson's disease patients with dopaminergic “ON state” FOG was two-fold. First, to explore unfamiliarity and habituation effects associated with wearing the HoloLens on FOG. Second, to evaluate the potential immediate effect of Holocue on alleviating FOG in the home environment. Three sessions were conducted to examine (1) the effect of wearing the unfamiliar HoloLens on FOG by comparing walking with and without the HoloLens, (2) habituation effects to wearing the HoloLens by comparing FOG while walking with HoloLens over sessions, and (3) the potential immediate effect of Holocue on FOG by comparing walking with HoloLens with and without Holocue. Wearing the HoloLens (without Holocue) did significantly increase the number and duration of FOG episodes, but this unfamiliarity effect disappeared with habituation over sessions. This not only emphasizes the need for sufficient habituation to unfamiliar devices, but also testifies to the need for research designs with appropriate control conditions when examining effects of unfamiliar wearable cueing devices. Holocue had overall no immediate effect on FOG, although objective and subjective benefits were observed for some individuals, most notably those with long and/or many FOG episodes. Our participants raised valuable opportunities to improve Holocue and confirmed our assumptions about current and anticipated future design choices, which supports ongoing Holocue development for and with end users.

Multi-Layered Blockchain Governance Game

The research designs a new integrated system for the security enhancement of a decentralized network by preventing damages from attackers, particularly for the 51 percent attack. The concept of multiple layered design based on Blockchain Governance Games frameworks could handle multiple number of networks analytically. The Multi-Layered Blockchain Governance Game is an innovative analytical model to find the best strategies for executing a safety operation to protect whole multiple layered network systems from attackers. This research fully analyzes a complex network with the compact mathematical forms and theoretically tractable results for predicting the moment of a safety operation execution are fully obtained. Additionally, simulation results are demonstrated to obtain the optimal values of configuring parameters of a blockchain-based security network. The Matlab codes for the simulations are publicly available to help those whom are constructing an enhanced decentralized security network architecture through this proposed integrated theoretical framework.

Integration in Mixed Methods Research Designs by Graduate Students at the University of Science and Technology

This chapter reports on a study that investigated how graduate students in the Faculty of Communication and Information Science at NUST were approaching integration in their mixed-methods research dissertations. There has been a concern that lack of expertise of what mixed-methods research is restricts the integrative capacity. Using a research synthesis method, the study investigated three graduate programmes, namely Master's degrees in Library and Information Science, Records and Archives Management, and Journalism and Media Studies from 2016 up to 2018. A total of 95 dissertations were reviewed, and 40 employed mixed-methods research design. It was discovered that integration was commonly done at methods and interpretation levels. Integration of qualitative and quantitative data sets resulted in confirmation (83), expanding understanding (27), and discordance (31). Graduate students dealt with discordant findings by either ignoring the discordance (20), seek corroboration with existing literature (7), or give priority to the quantitative strand (4).

Anxiety Confronted by EFL Students in Instructional Listening Class

The barrier of learning listening is experienced by students that make them feel anxious. Consequently, it easily effects their performance during listening class. Therefore, this study is aimed to describe the anxiety types and causes of anxiety confronted by EFL students in listening class at university level. To accomplish this aim, Qualitative research designs was applied by the researchers. The research subjects were English Department Students in IAIN Tulungagung. The research data were obtained through observation in listening class and in-depth interviews to the six most anxious informants. Then, the collected data was analyzed by data reduction, data presentation, and conclusion drawing. In order to check trustworthiness of data, theoretical and methodological triangulations applied. The result of this study was revealed that there were six symptoms of anxiety confronted by the students in listening class, that were categorized as the type of Arousal Anxiety (ArA), Apprehension Anxiety (ApA), and Mixed Anxiety (MA) also revealed five causes of anxiety. Those results inform the lecturer to be understood about students’ anxiety and start to create the joyful learning in listening class so that they are more comfortable following the class.

Exploring careers through a qualitative lens: an investigation and invitation

PurposeIn this paper, the authors investigate and celebrate the contributions that qualitative research has made to Career Development International (CDI) and careers scholarship over the past 25 years. The authors highlight the positive impact of understanding the “lived/emic experiences” of individual career actors using qualitative research designs and identify areas for future research.Design/methodology/approachThe authors employ multiple approaches in their investigation. The authors’ enquiry is part conceptual, part critical analysis and part bibliometric visualisation of qualitative papers published in CDI.FindingsThe authors identify the underlying ontological and epistemological assumptions of qualitative research, and the key tenets and contributions of qualitative research published in CDI. Their bibliometric analysis shows the interrelatedness and frequency of topics addressed by qualitative research and published in CDI, revealing areas for further research. While identifying some of the key criteria for rigor in qualitative research, the authors also engage with emerging calls to avoid rigid templates in how qualitative research is designed and implemented. In this regard, authors echo calls for “methodological bricolage” as an approach to qualitative research in the study of careers.Originality/valueThis is the first bibliographic and visual analysis of qualitative research published in a single journal. The authors offer this investigation as a way of looking back and as an invitation looking forward, encouraging further qualitative research in anticipation of future theoretical developments in career scholarship.
