Abstract

Purpose

A botnet is a network of computers on the internet infected with software robots (or bots). There are numerous botnets, and some of them control millions of computers. Cyber criminals use botnets to launch spam e‐mails and denial of service attacks; and commit click fraud and data theft. Governments use botnets for political purposes or to wage cyber warfare. The purpose of this paper is to review the botnet threats and the responses to the botnet threats.

Design/methodology/approach

The paper describes how botnets are created and operated. Then, the paper discusses botnets in terms of architecture, attacking behaviors, communication protocols, observable botnet activities, rally mechanisms, and evasion techniques. Finally, the paper reviews state‐of‐the‐art techniques for detecting and counteracting botnets, and also legal responses to botnet threats.

Findings

Botnets have become the platform for many online threats such as spam, denial of service attacks, phishing, data thefts, and online frauds. Security researchers must develop technology to detect and take down botnets, and governments must develop capacity to crack down on botmasters and botnets. Individual computer owners must diligently take measures to keep their computers from becoming members of botnets.

Originality/value

The paper provides a review of current status of botnets and a summary of up‐to‐date responses to botnets in both technical and legal aspects, which can be used as a stepping stone for further research.

Abstract

Purpose

This paper aims to provide a comprehensive overview of the challenges and employee development strategies for executives and managers when managing flexible work systems.

Design/methodology/approach

The paper takes an employee development perspective to discuss management strategies of flexible work systems. Research findings on the effects of work flexibility through flexible work systems, the challenges and the development strategies that executives and managers can use were reviewed from multi-level perspectives.

Findings

The flexible work system is the new normal in the workplace. Lack of social and face-to-face interactions reduces employees’ social learning, jeopardizing managerial justice and weakening the culture. To remain competitive and retain talented employees, executives should reexamine their current employee development strategies and implement new strategies that fit the characteristics of flexible work systems.

Originality/value

To the best of the authors’ knowledge, this is the first comprehensive review of employee development strategies for flexible working arrangements. The paper provides practical guidelines and insights for executives and leaders managing employees under various flexible work systems.

Abstract

Purpose

Given that 45% of new businesses fail in their first five years (US Bureau of Labor Statistics, 2020), individuals often observe others' entrepreneurial failures (EFs) in their vicinity. The purpose of this paper is to review the effects of vicarious EFs on individuals by proposing both entrepreneurial self-efficacy and entrepreneurial identity aspiration as mediators, which are widely studied proximal antecedents of entrepreneurial intent.

Design/methodology/approach

Using structural equation modeling, the authors empirically test survey data collected from 10,020 college students across 46 colleges or universities in Brazil. The hypothesized model examines the mediating effects of vicarious EFs on individuals' entrepreneurial intent via entrepreneurial self-efficacy and entrepreneurial identity aspiration.

Findings

The findings confirm that vicarious EFs negatively affect one's entrepreneurial self-efficacy and that entrepreneurial self-efficacy mediates the effect of vicarious EFs on one's entrepreneurial intent. On the other hand, vicarious EFs positively affect one's entrepreneurial identity aspiration, and entrepreneurial identity aspiration mediates the effect of vicarious failures on entrepreneurial intent.

Originality/value

The entrepreneurship literature focuses mainly on the consequences of EF on those entrepreneurs who have experienced failure. However, there is a lack of knowledge regarding how that failure impacts others in its vicinity. This study provides new insight into the effects of vicarious EFs in facilitating individuals' entrepreneurial intent and presents theoretical and practical implications to promote greater levels of entrepreneurial intent in individuals.

Abstract

Purpose

The purpose of this paper is to examine the dynamic effects of users’ initial experience and user attachment on downloading information-seeking (e.g. news, map, education) and -sharing (e.g. messenger, chatting, social networks) applications.

Design/methodology/approach

From one of the largest application stores in South Korea, 225 applications were examined through analysis of 1.5 years of download records. Logistic regression and Bayesian models including time-varying coefficients were used.

Findings

Over time, the download patterns of users of the app market become dynamic. In the initial stage, users have a tendency to download apps of similar types. For example, users who initially download information-seeking applications continue to download these types of applications more frequently than information-sharing applications. In the later stage, however, users tend to download applications that accord with their attachment intensity. Users who want to share information with others are more likely to download information-sharing applications as compared to information-seeking ones. Finally, this tendency persists with the accumulation of more experience.

Research limitations/implications

This study applies existing models and theories from previous research to the app market, such as state dependence, intrinsic motivation, and time-varying coefficient models. However, this study focuses on information-seeking and -sharing applications. Therefore, further study is needed in order to extend the findings to other types of applications, including games, paid applications, and so on.

Practical implications

This study provides valuable information for marketing managers running application stores and app developers who want to maximize performance. In the initial stages when users download apps, app market managers must recommend apps with consideration of both the users’ attachment and their initial experience, but after app users have accumulated some experience, only user attachment should be considered as a criterion for recommendations.

Originality/value

This is a unique study in which users’ download behavior regarding information-seeking and -sharing applications is analyzed using long-term actual data.

Abstract

Purpose

Based on the humane entrepreneurship perspective, this study examines the mediating relationship of organizational trust (OT) between corporate entrepreneurship (CE) and turnover intention (TI). In addition, it tests the moderating role of top talent management (TTM) between corporate entrepreneurship and OT.

Design/methodology/approach

This study uses a multi-level research method to provide a conceptually comprehensive understanding of how CE works in an organization by testing the relationship between organizational practices and employees' outcomes.

Findings

This study found the mediating role of OT between cooperate entrepreneurship and employee TI. The authors also found the moderating role of TTM between CE and OT.

Originality/value

In this study, it is meaningful that OT is set as a mediating variable to identify the relationship between CE and workers' attitudes (TI). Although previous studies have shown a positive correlation between CE and TI, there was a lack of specific research on the indirect process by which CE affects workers' attitudes. This study looked more closely at the impact of CE on workers' attitudes using a multiple quasi-analysis.

Abstract

Purpose

The purpose of the study is to investigate the effects of interactivity and vividness on perceived usefulness and perceived enjoyment and their consequent impacts on consumer behavioral responses in a retail furniture VR store context. Considering the lack of VR empirical research, the indirect effect of interactivity and vividness on perceived usefulness and perceived enjoyment through telepresence and the moderating effect of consumer previous experience with VR are also included.

Design/methodology/approach

A commercial IKEA VR store was chosen for the study. Head-mounted display (HMD) VR headsets were employed for the VR shopping experience. The study was conducted at a laboratory at a large university in the southeastern United States. A total of 146 college students participated in the study.

Findings

Vividness had significant positive effects on perceived usefulness and perceived enjoyment, which in turn influenced attitude towards VR and behavioral intentions. Interactivity did not have positive impacts on perceived usefulness and perceived enjoyment. However, it indirectly affected perceived usefulness and perceived enjoyment through telepresence. The findings also proved the moderating effect of consumer previous VR experience between interactivity and perceived usefulness and between interactivity and perceived enjoyment. The relationship between attitude and behavioral intentions was also positive.

Originality/value

Notwithstanding the benefits of VR in relation to its utilitarian, hedonic, and behavioral values, little is known about consumers' responses towards the usage of VR as a shopping tool. The present study can be considered as a starting point in understanding the usefulness of VR from consumer and managerial perspectives. The findings of VR indicated in the study will help practitioners understand the urgency of adopting VR in a retail setting.

Abstract

Purpose

The purpose of this paper is to examine the relationship between high commitment human resource practices (HCHRPs), conceptualized at the workplace level and employees’ attitudes, including affective commitment (AC) and turnover intention (TI). The study also tests the moderating role of cooperative labor–management relations (CLMR) between HCHRPs and organizational trust (OT).

Design/methodology/approach

Based on social exchange theory and trust commitment theory, the authors build a research model that explains employee behavior and empirically prove the model by using samples of 407 employees from South Korea. This study uses hierarchical linear regression and cross-level hypotheses based on hierarchical linear modeling.

Findings

The results demonstrate the positive impact of HCHRPs on an AC and TI, through OT. However, no moderating effect of CLMR between human resource management (HRM) practices and OT is observed.

Originality/value

Few theory-based studies test the direct linkage between HRM practices and outcomes. This study is designed with a multi-level research method to provide a conceptually comprehensive and deeper understanding of how HRM practices work in an organization by testing the relationship between organizational practices and employees’ outcomes.

Abstract

Purpose

The purpose of this study is to investigate the effects of visual and verbal information presentations on mental imagery, perceived informativeness and purchase intention. The study assesses two types of product-related information: (1) visual information: static product images and augmented reality (AR) and (2) verbal information: abstract and concrete product reviews.

Design/methodology/approach

A total of 320 mobile consumers participated in the experiment. To increase external validity, this study was conducted in an existing digital shopping environment.

Findings

The results suggest that AR has a greater effect on consumers' shopping outcomes than static images. The findings further reveal that concrete product reviews are important in increasing mental imagery, perceived informativeness and purchase intention when visual information does not provide an AR function.

Originality/value

This study contributes to the current literature by providing empirical support for AR effects and concrete reviews on consumer responses. The results further provide an important perspective for retailers seeking ways to develop effective information presentations in digital retailing.

Abstract

Purpose

The purpose of the study is to investigate how mental imagery evoked from sensory in-store experience influences consumer anticipatory emotion, perceived ownership and decision satisfaction which eventually impact positive consumer responses such as behavioural intent. In this study, gender difference is proposed as a moderator to completely understand the role of mental imagery in the in-store decision-making process.

Design/methodology/approach

Using a market research agency in South Korea, an online survey was employed to collect data. A total of 455 useable respondents (men = 224 and women = 231) largely living in the two most populous provinces in South Korea (i.e. Seoul and Gyeonggi provinces) completed the survey. A number of path analyses were conducted to test hypotheses.

Findings

The results of the study showed that mental imagery evoked from sensory product experience played a critical part in facilitating the consumer decision-making process by influencing anticipatory emotion and perceived ownership. The relationship among anticipatory emotion, perceived ownership, decision satisfaction and behavioural intent was significant except for the relationship between perceived ownership and behavioural intent. This study further indicated that the way mental imagery influences the in-store decision-making process differs between men and women.

Originality/value

The effect of mental imagery in a physical retail context is largely ignored. This study addressed the crucial role of mental imagery in a physical apparel retail setting and examined its impact on consumer decision-making processes. By exploring how to enhance consumers' in-store sensory shopping experiences through mental imagery to influence their positive shopping outcomes, this study offers vital insights into how retailers operating physical stores can successfully utilize their stores.
