While the idea of the resilience of information systems security exists, there is a lack of research that conceptualizes, defines and specifies a way to measure it as a dynamic capability. Drawing on relevant cybersecurity and dynamic capabilities literature, this study aims to define Information Systems Security Resilience (ISSR) as a “dynamic capability of a firm to respond to, and recover from, a security attack” and test it as a new construct.

The authors employ a methodology including multiple phases to develop and test this construct of ISSR. The authors first interview senior managers from various organizations to establish the face validity of the construct; then develop and analyze a pilot survey for internal validity and reliability; and finally, design and deploy a field survey to test and externally validate the construct.

The authors conceptualize and define the construct of ISSR as a dynamic capability, develop a scale for its measurement and test it in a pilot and field survey. The construct is valid, and the measurement tool works. It demonstrates that resilience is something that is done, rather than had. As a capability, organizations need to track and measure ISSR, which is what this tool provides the ability to do.

This research contributes to the information systems and cybersecurity literature and offers valuable insights for organizations to manage their security effectively.

Training is one of the key dimensions of internal marketing. Virtual reality (VR), a computer technology that replicates an environment (real or imagined) and simulates a user’s physical presence in that environment to allow for user interaction, offers unique opportunities from a training perspective, such as allowing users to improve their skills without the consequence of failing real customers or the need to be in the real environment physically. This study aims to focus on comparing the effectiveness of VR hospitality training with that of real-world hospitality training.

This study adopts situated cognition theory to empirically test the effect of the awareness of contextual variables (social interaction, location and task) on learning and compare learning outcomes between tourism training in VR and real-world experimental settings.

Results indicate that location and task awareness enhance cognitive absorption, but social awareness does not influence cognitive absorption. There is no significant difference between training in real-world and VR environments. Finally, cognitive absorption has a positive effect on mental model change (the learning outcome).

This result advances the theoretical understanding on the significance of learning context by applying situated cognition theory in hospitality training and has significant implications for training that aims for rigor and efficiency within cost, location and time constraints.

培训是内部营销的关键维度之一。 虚拟现实 (VR), 一种复制某种环境（真实的或想象的）并模拟在该环境中实质性存在的用户的计算机技术并且允许用户交互, 从培训的角度来看提供独特的机会, 例如允许用户在没有培训的情况下提高他们的技能避免承担损失真实客户的后果或需要实际身处真实环境中。 本研究的重点是比较 VR 酒店培训与现实世界的招待培训的效果。

本研究采用情境认知理论对情境变量（社交互动、位置和任务）的认识对学习和比较 VR 和现实世界实验环境中的旅游培训之间的学习成果进行实证检验。

结果表明, 位置和任务意识增强了认知吸收, 但社会意识不影响认知吸收。 在现实世界和 VR 环境中的训练之间没有显着差异。 最后, 认知吸收对心理模式改变（学习结果）有显著积极作用。

该结果通过在酒店培训中应用情境认知理论促进了对学习情境重要性的理论理解, 并对旨在成本、地点和时间限制内实现严谨和高效的培训具有重要意义。

General theories have been criticized for their inability to explore the mechanics of more specific domain knowledge and understand how, when and where general theory applies to and extends domain knowledge in supply chain management (SCM). Middle-range theorizing (MRT) is a potential solution to this limitation. This paper aims to assist researchers in understanding the relationship between MRT and general theorizing (GT) and connecting MRT research findings to general theory.

This research provides a structured literature review of 518 articles, from eight journals in logistics, SCM and operations management. Theoretically based articles are analyzed by primary domain and SCM context.

There are frameworks for conducting MRT; however, the literature does not sufficiently assist researchers in understanding how middle-range (MR) theory should relate to general theory. Findings include a better understanding of underserved areas in SCM, guideline frameworks for understanding when to apply MRT, when to apply GT and how MRT knowledge can be connected to SCM domain knowledge.

This study provides a timely and appropriate compilation of theory research in SCM, including significant implications for both theory and practice, by helping to articulate the evolving philosophy of science in SCM.

This paper aims to review logistics and supply chain management topics where theories have been applied to better understand the supply chain management (SCM) discipline identity. The purpose is threefold: to identify research topics in logistics and supply chain management where one or more theories have been examined; provide commentary on the theories that have been applied to the various logistics and SCM research topics; and to provide reference material and direction for future research.

This structured literature review (SLR) examines research papers in logistics and SCM from 1991 to 2015 published in eight leading academic journals. Papers in the data set are grouped by topic and further analyzed in terms of research method, purpose, year and journal.

This research categorizes papers by the topics that were studied to understand important insights about how these topics have been examined by researchers. Within each topic area, theories that researchers have used to investigate the topics are identified. This method exposes insights such as: how topics have evolved over time, which topics have lost prominence, which topics may be particularly promising for future research and how topics are treated in the literature.

Despite multiple calls for clarification regarding how theory has been used in logistics and SCM, the logistics and SCM disciplines continue to grow without adequate research on how theory has been used to examine SCM topics. This SLR therefore provides a broad compilation of logistics and SCM research that uses named theories and that is organized by SCM topic to better understand the SCM discipline.

The focus of this paper is to identify factors determining willingness to pay, preferences for geographic areas, and preferred times for study abroad and semester abroad programs.

A unique survey instrument is utilized, which was administered to a section in the college of business of a regional university in Florida. The survey itself contains a variety of demographic questions. The survey also includes questions to assess students' financial conditions, interest in study abroad, parents' influence on study abroad, international experience, international program awareness, and willingness to pay for study abroad.

Results reported here reveal that students consider various factors in their decision to participate in such a program, including not only the cost of the program, but also the academic and cultural components and the popularity of the professor. Factors determining the willingness to pay, preferences for geographic areas, and preferred times for study abroad and semester abroad programs also play a role.

There are biases in the sample limiting the generalizability of the results. Also, extra credit was offered as a reward for completing the survey, which may result in some students providing unreliable answers.

The results of the study should be useful for any university that is currently developing a study abroad plan from both a marketing perspective and an attendance‐maximization viewpoint.

This study is intended to be a first step in synthesizing and summarizing factors important to students as they make decisions regarding study abroad programs.

This study aims to know whether board composition is effective in improving firm performance and particularly to determine whether this relationship varies across different levels of performance, that is, companies with very low performance, low performance, moderate performance, high performance and very high performance.

The authors use a data set covering 213 Indian companies registered on S&P Bombay Stock Exchange 500 Index over the period 2001 to 2019 by using Tobin's Q as a performance parameter. The study applies the quantile regression technique and compares the results with fixed effect generalized least squares (GLS) regression.

The findings reveal that board size positively affects the company's performance across all quantiles. Independent directors negatively impact the performance of companies across all quantiles. However, the strength of these relationships increases with increase in performance, thereby supporting agency theory and stewardship theory, respectively. The effect of executive directors on the performance of the companies varies across quantiles. The effect is adverse at moderate and high quantiles only.

The findings provide some grounds for regulators to exercise caution while designing board composition guidelines, keeping in mind the unique internal environment of each company which ultimately affects their performance levels. Similarly, Indian companies are also suggested to compose their boards keeping in mind their performance levels.

The study contributes towards the debate on the board composition and firm performance relationship by adding to the agency theory and stewardship theory that all the companies cannot have the similar board composition. Rather its composition depends upon the performance levels of the companies.

Today the mobile apps are helping customers in every means of their life by exploring information related to electronic items and even for food items also. Therefore, the main aim of this study is to examine the influencing role of psychological and technological attributes on customer conversion to use food ordering apps.

Convenience sampling method was used to collect responses from the customer's age between 18 and 35 years to get more representation of society. 374 customer's data has been used for structural equation model analysis with the help of SmartPLS 3.0 and SPSS-20 software.

Findings showed that customer conversions are positively influenced by perceived ease of use, perceived usefulness, perceived incentives, perceived information, customer relationship management and order management system. In contrast, the perceived price and visual design show insignificant influence.

Research outcome provides some valuable insights to provide direction to all online food aggregators to design their apps according to customers need. Thus, the authentic customer reviews and the facility of providing feedbacks are very fruitful for attracting new user while using and placing orders through theses apps.

Study suggested that observing satisfaction and dissatisfaction levels of the customer helps in enhancing the facilities of food ordering apps, so that the customer would enjoy the whole order process seamlessly, which automatically leads to customer conversions.

Major contribution of this study is the empirical analysis of psychological and technological attributes on customer's conversion towards food ordering app.

Solar energy applications are limited because of its intermittent and discontinuous availability with respect to time. Hence, solar energy thermal conversion systems need integration with thermal storage units (TSUs) to use solar energy in off sunshine hours. This paper aims to perform thermal analysis of a solar air heater (SAH) integrated with a phase change material (PCM)-based TSU to supply hot air during night period.

An experimental setup with TSU as main component was prepared with SAH at its upward side, food chamber at its downward side as subcomponents. In TSU, paraffin wax was used as thermal energy storage material. Mass flow rate of air considered as an input parameter in the experiment. Two different absorber plates, namely, plane and ribbed absorber plates were used for the experimentation. Each day for a fixed mass flow of air, observations were made during charging and discharging of PCM.

Nusselt number and convection heat transfer coefficients were analytically calculated by considering flow through TSU as external flow over bank of tubes in a rectangular duct. A temperature drop of around 7-8°C during charging of PCM and temperature rise of around 4-5°C during discharging of PCM was observed from the experimental results. The average practical efficiency of TSU with ribbed absorber plate SAH during charging and discharging of PCM was 22 and 6 per cent, respectively, higher than that of TSU with plane absorber plate SAH.

There are no limitations for research on SAH integrated with TSU. Different PCM including paraffin wax, Glauber’s salt, salt hydrates and water are used for thermal storage. Only limitation is lower efficiency of SAH integrated with TSU because of lower heat transfer coefficients with air as working medium. If it can improve heat transfer coefficients of air then heat transfer rates with these units will be higher.

There are no practical limitations for research on SAH integrated with TSU. Sophisticated instrumentation is needed to measure flow rates, temperatures and pressure variations of air.

In poultry farms during night, chicks cannot survive at cold climatic conditions. Hence, hot air should be supplied to poultry farms whenever the atmospheric temperature drops. It is proposed that, in combination with TSUs, heat produced by SAH is stored in day time in the form of either sensible or latent heat and is retrieved to provide hot air in the night times. This will reduce total operating costs in poultry farms.

Conventionally, people are producing hot air by combusting coal in poultry forms. This cost around Rs. 75,000 per month for a batch of 225 to 250 chicks in a poultry form. Hot air could be produced economically during off sunshine hours from SAH integrated with TSU compared to the conventional method of coal burning. Present experimental investigations conducted to fill the literature gap in this area of research and to design a SAH integrated with TSU to produce hot air for poultry forms.

This paper intends to discover, analyze and construct a model that may be used to measure the interactions between major factors which are identified by expert opinion and literature review for sustainable maintenance specific to manufacturing industries using the total interpretive structural modeling (TISM) approach.

In total, 12 factors were acknowledged from the literature review and the opinions of experts from manufacturing industries. Scheduled interviews with the employees were conducted by using the questionnaire which is developed from the identified 12 factors in order to find the interrelationships among these factors. The TISM approach is used for analyzing factors' interrelationships. The Matrice d'Impacts Croises Multiplication Appliques a un Classement (MICMAC) approach is used to identify the key factors which influence sustainable maintenance.

This paper found 12 factors that have ascendancy over the sustainable maintenance practices in the industry by reviewing the literature and consulting industry experts to realize the linkage between the factors. The results found that availability rate, adopting government policies, training and education are key factors that influence sustainable maintenance.

The proposed model would be valuable for experts to understand the factors influencing sustainable maintenance in the industry. This model can be used by an organization's maintenance managers to implement sustainable maintenance practices in their plants.

This study analyzes the interrelationship between factors influencing sustainable maintenance in manufacturing industries, which is a new effort in this domain of practice.
