We argue that a fundamental issue regarding how to search and how to switch between different cognitive modes lies in the decision rules that influence the dynamics of learning and exploration. We examine the search logics underlying these decision rules and propose conceptual prompts that can be applied mentally or computationally to aid managers’ decision-making.

By applying Multi-Armed Bandit (MAB) modeling to simulate agents’ interaction with dynamic environments, we compared the patterns and performance of selected MAB algorithms under different configurations of environmental conditions.

We develop three conceptual prompts. First, the simple heuristic-based exploration strategy works well in conditions of low environmental variability and few alternatives. Second, an exploration strategy that combines simple and de-biasing heuristics is suitable for most dynamic and complex decision environments. Third, the uncertainty-based exploration strategy is more applicable in the condition of high environmental unpredictability as it can more effectively recognize deviated patterns.

This study contributes to emerging research on using algorithms to develop novel concepts and combining heuristics and algorithmic intelligence in strategic decision-making.

This study offers insights that there are different possibilities for exploration strategies for managers to apply conceptually and that the adaptability of cognitive-distant search may be underestimated in turbulent environments.

Drawing on insights from machine learning and cognitive psychology research, we demonstrate the fitness of different exploration strategies in different dynamic environmental configurations by comparing the different search logics that underlie the three MAB algorithms.

Considers the factors which influence Taiwanese decisions to buy Japanese or US refrigerators, basing the conclusions on the results of a survey of 586 respondents drawn from Taiwan’s four largest cities – Taipei, Kaoshiung, Taichung and Tainan. Describes how the questionnaires were constructed and pretested, and explains how the data was recorded (using a 5‐point Likert‐type scale) and analysed (using factor analysis and t‐tests). Tests particularly for cultural values of the Chinese, consumer ethnocentrism, openness to foreign culture, country image, and consumer sophistication. Finds that, despite the longer presence of Japanese goods in Taiwan, Japan’s proximity to Taiwan, and more cultural similarities between the Japanese and Taiwanese, Taiwanese consumers rate the USA’s country image factor higher than Japan’s, with consequent implications regarding intention to buy US goods. Recommends that US marketers build on their advantageous country image when they promote US appliances in foreign markets. Cautions against making too much of this snapshot data but concedes that further research into different foreign markets, different appliances, and with a longitudinal approach, would ascertain if findings are consistent with this survey, which has obvious benefits as new markets, such as China and India, open up to western goods and appliances.

The newsvendor problem is fundamental to many operations management models. The problem focuses on the trade-off between the gains from satisfying demand and losses from unsold products. The newsvendor model and its extensions have been applied to various areas, such as production plan and supply chain management. This chapter examines the study about newsvendor problem. In this research, there is a review of the contributions for the multiproduct newsvendor problem. It focuses on the current literature concerning the mathematical models and the solution methods for the multiitem newsvendor problems with single or multiple constraints, as well as with the risks. The objective of this research is to go over the newsvendor problem and bring into comparison different newsvendor models applied to the flower industry. A few case studies are described addressing topics related to the newsvendor problem such as discounting and replenishment policies, inventory inaccuracies, or demand estimation. Three newsvendor models are put into practice in the field of flower selling. A full database of the flowers sold by an anonymous retailer is available for the study. Computational experiments for practical example have been conducted with use of the CPLEX solver with AMPL programming language. Models are solved, and an analysis of different circumstances and cases is accomplished.

Historically, research in organizational behavior has denied and even denounced the presence and impact of emotions in the workplace. Today, after little more than 10 years of research on emotions in the workplace, organizational behavior scholars look to emotions as an important determinant of nearly every facet of workplace behavior. From interpersonal behavior, to team performance, and strategic decision-making in top management teams, researchers have argued that the role of emotions is fundamental to our understanding of these organizational processes. Research on emotions in the workplace has had a fast and furious growth, facilitated by a lack of critical reflection upon the limits of bounded emotionality as a framework for understanding individuals’ actions in organizations. It is undeniable that emotions influence some facets of organizational behavior. But the questions of interest in this chapter are, in which areas of organizational behavior do emotions play a critical role in the determination of individual and organizational outcomes and under what conditions?

This monograph reports on the strategic and operational roles of learning and development (L&D) professionals in Irish, UK European and US organisations including multinational corporations, small to medium enterprises, the public sector and not for profit organisations. This paper aims to investigate the contextual factors influencing L&D roles in organisations, the strategic and operational roles that L&D professionals play in organisations, the competencies and career trajectories of L&D professionals, the perceptions of multiple internal stakeholders of the effectiveness of L&D roles and the relationships between context, L&D roles, competencies/expertise and perceived organisational effectiveness.

The study findings are based on the use of multiple methods. The authors gathered data from executives, senior managers, line managers, employee and L&D professionals using multiple methods: a survey (n = 440), Delphi study (n = 125) and semi-structured interviews (n = 30).

The analysis revealed that L&D professionals increasingly respond to a multiplicity of external and internal contextual influences and internal stakeholders perceived the effectiveness of L&D professionals differently with significant gaps in perceptions of what L&D contributes to organisational effectiveness. L&D professionals perform both strategic and operational roles in organisations and they progress through four career levels. Each L&D role and career level requires a distinct and unique set of foundational competencies and L&D expertise. The authors found that different contextual predictors were important in explaining the perceived effectiveness of L&D roles and the importance attached to different foundational competencies and areas of L&D expertise.

This is one of the few studies to have investigated the L&D professional role in organisations from the perspective of multiple stakeholders using multiple research methods.

OUR readers may be amused this month by the microfilm imaginings of our correspondent in “Letters on Our Affairs,” but there is undoubtedly a more marked disposition now than formerly to reduce to a mechanism many of the usual routines of libraries. We suppose routine is always mechanical, is repetitive and, for the enterprising ambitious library worker, a matter of boredom. How far the “electronic brain” and other more recent developments of science can be adapted to our simple processes remains to be seen, but all experiment is good even if it does not survive the initial stage. What is to be most feared in any profession is the standardizing inflexibly of its techniques ; that way lies its old age, perhaps its petrification. It is for this reason that we welcome such things as those we have already discussed at times in our pages—the central cataloguing experiment of Harrods, the punched‐card vouchers and other records sponsored (so far as libraries are concerned) by Mr. T. E. Callender, the highly mechanised method of classing propounded by Dr. Ranganathan, the placing of D.C. numbers on the title pages of the books they publish by Jonathan Cape and Harrap, the visible fines receiving box and many more such things. No one uses them all. They free librarians, it is urged, for more specifically library service. We hope that they do. We have always before us the undoubted truth that the good man scraps methods that are obsolescent and the librarian (if one now exists) who is not a business man—especially if he is charged with a large library—is a somewhat pathetic person.

Since its publication in 1996, Affective Events Theory (AET) has come to be regarded as the seminal explanation for structure, causes and consequences of affective experiences at work. AET does not, however, elucidate why, how, and when objects and events in the workplace trigger moods and emotions which in turn influence cognitive and behavioral outcomes. Consequently, AET does not yet provide us with a theoretical basis upon which to predict the way in which contextual, cognitive, motivational, or individual factors might moderate the impact of workplace events on affective states and subsequent behavior. In this chapter, we outline the central tenets of AET, and review a model of the processes underlying AET, with a view to understanding individual differences in the manifestation and consequences of affect in the workplace.

The purpose of this study was to gain a holistic view of pro-environmental behavior (PEB) among hospitality and tourism consumers through a systematic review of empirical studies. Based on this comprehensive review, this study demonstrates how the literature has been created and has evolved over time, thereby providing proposals for future research agendas.

The preferred reporting items for systematic reviews and meta-analyses method was used as a rigorous searching method to provide an updated picture of the research on the PEBs of consumers in hospitality and tourism contexts. A total of 234 empirical studies from both hospitality and nonhospitality publications were selected for the review.

The results reveal a growing interest in PEB in the hospitality and tourism context. Focal points, theories and research designs used to explain PEB among hospitality and tourism consumers were identified. In addition, the findings from the cross-tabulation analyses have provided valuable insights for tourism and hospitality research in this area.

Based on the research findings, this study makes significant contributions to the literature by providing theoretical and practical implications with detailed directions for future researchers and practitioners.

This study offers one of the first reviews to comprehensively and systematically analyze the empirical research into PEBs among hospitality and tourism consumers. PEB has received significant attention from researchers, practitioners and those policymakers concerned with the sustainability of environments. The findings of this research provide a comprehensive overview of the literature relating to hospitality and tourism through the identification of gaps that require further investigation. Future suggestions to assist practitioners and policymakers in eliciting PEBs are also discussed.

The dual epidemic of non-communicable diseases (NCDs) and human immuno-deficiency virus (HIV) in Sub-Saharan Africa has increased substantially in recent years, with cardiovascular disease representing a significant contributor to the regional burden of disease. Very little is known about the cardiovascular health of people deprived of their liberty in the region. The purpose of this study was to collate extant literature on the topic.

A scoping review mapped and described what is known about cardiovascular disease in prison populations in Sub-Saharan Africa. A systematic search of empirical literature with no date limitation was conducted in English. Sixteen studies representing six Sub-Saharan African countries (Cameroon, Nigeria, Guinea, Burkina Faso, Ghana and Ethiopia) were charted, categorised and thematically analysed.

Seven key themes were identified: custodial deaths and autopsy; cardiorespiratory fitness and exercise; cardiovascular disease and elderly people in prison; cardiovascular disease and women in prison; dietary deficiencies; influence of sleep patterns on cardiovascular disease; and other associated risk factors. Most natural deaths at autopsy of custodial deaths were due to cardiovascular disease. Cardiorespiratory fitness was low in prisons, and poor sleep patterns and dietary deficiencies are likely contributors to the burden of cardiovascular disease in prisons. The needs of elderly and female prison populations are ill-considered.

To the best of the authors’ knowledge, this is the first known attempt to scope extant literature on cardiovascular disease in Sub-Saharan African prisons. A strategic focus on the cardiovascular health of people in prison is warranted. Routine monitoring and expansion of existing prison health-care services and integration of NCD services with infectious disease (HIV and tuberculosis) programmes in prisons are required.
