Abstract
Purpose
We study the problem of finding optimal locations for a suite of defense assets in order to protect high-value tactical and strategic infrastructure across a vast geographical area. To this end, we present a multi-type with non-overlapping coverage requirement as an extension to the classical formulation for the maximal covering location problem (MCLP).
Design/methodology/approach
In our case study, we use open source geographic and demographic data from Canadian sources as inputs to our optimization problem. Due to the complexity of the MIP formulation, we propose a hybrid metaheuristic solution approach, for which a genetic algorithm (GA) is proposed and integrated with local and large neighborhood search operators.
Findings
Extensive numerical experiments over different instances of the proposed problem indicate the effectiveness of the GA-based solution in reducing the solution time by a factor of ten compared to the CPLEX commercial solver while both approaches obtain solutions of similar quality.
Research limitations/implications
This research is limited to location planning of defense assets leveraging geospatial data of Canada. However, the diverse Canadian geography is among the most challenging given broad variability in population density and the vast size of the country leading to a large search space having substantial variability in fitness performance.
Practical implications
Our findings demonstrate that for large-scale location searches, the GA with a local neighborhood search performs very well in comparison to CPLEX but at a fraction of the execution time.
Originality/value
Our findings provide insight into how to make improved decisions for the placement of deterrence and defense systems and the effectiveness of a hybrid metaheuristic in addressing associated computational challenges.

Abstract
Purpose
The purpose of this paper is to objectively evaluate the cost benefit of applying corrosion prevention coatings throughout a mid-life logistics fleet supporting the Canadian Army.
Design/methodology/approach
A database of maintenance records for an Army logistics vehicle throughout a four-year study period is mined. Statistical analysis (primarily ANOVA) accounting for the frequency of treatment and geographic region is executed.
Findings
Statistical analysis indicates counter-intuitive results. Vehicles that are most frequently treated to prevent corrosion incur the highest maintenance costs. Consultation with operational units suggests that a strategic approach to corrosion prevention is largely absent. Instead, vehicles are treated on an ad hoc basis, or – equivalently – on an as available basis.
Practical implications
Among high tempo organizations, vehicles most readily available to maintenance support are those that are in the greatest state of disrepair. Vehicles that are in better condition are preferred by operators for daily operations and are not available. Consequently, the vehicles that are subject to preventative maintenance most often are those near their end-of-life or are in disrepair and therefore gain little through further investments in corrosion prevention initiatives.
Originality/value
Clearly, having corrosion prevention compounds applied to a fleet on an ad hoc basis suffers from the natural bias occurring among operators to retain vehicles in best condition for operational purposes. Corrosion prevention requires a more strategic approach including disciplined maintenance operations in order to provide dividends on a fleet-wide basis.

Abstract
Subject area of the teaching case:
The case is particularly well suited to entrepreneurship, marketing, technology, innovation, or strategy courses.
Student level:
This teaching case is aimed at postgraduate students in management or business programmes.
Brief overview of the teaching case:
This case follows the Kenyan healthcare tech company Savannah Informatics as they contemplate how the company will continue to grow in a post-pandemic world. Savannah is the market leader in electronic claims validation solutions for the Kenyan healthcare system. Their flagship product, the digital platform Slade 360, allows health insurers, healthcare providers, and patients to share claims information for health services in real time, drastically reducing payment transfer times, incidents of fraud, and account errors. The Covid-19 pandemic and the subsequent lockdown mandates from the Kenyan government have reduced short-term revenues by driving down hospital visits for citizens overall, but they have also created a demand for telemedicine and more online healthcare solutions. CEO John Muthee and his co-founders are left to consider their options for growing Savannah Informatics: expanding into new markets, creating more solutions for their insurance and provider customers in Kenya, or diversifying.
Expected learning outcomes:
Identify the key challenges facing Savannah
Analyse the organisation using the 5Cs model (company, customers, competitors, collaborators and context) and VRIO (value, rarity, imitability, and organisation) analysis
Assess the growth opportunities available to Savannah and make recommendations

Abstract
Purpose
This paper aims to empirically test, in the Niger Delta region of Nigeria, the external perceptions which hold that a firm that has acted in a socially irresponsible manner can have negative consequences, as an organisation’s success and very survival depends, in part, on satisfying normative expectations from its environment.
Design/methodology/approach
A purposive sample of 28 respondents was selected from three communities within the region. In addition, 20 in-depth interviews took place with oil workers, community leaders and elders within the region. These interviews lasted for approximately an hour and were transcribed verbatim.
Findings
Drawing on qualitative research methodology, it is proposed that socially responsible investment could promote and facilitate business and social cohesion between corporations and broader communities that impinge on the company, rather than simply viewing business practice exclusively from an economic or political point of view.
Research limitations/implications
This study has examined a small range of companies from an interpretivist ethnographic position in the Niger Delta region using data collected from interviews and observations. Future research could take a more positivistic position and explore a wider range of companies using a variety of data collection methods.
Practical implications
Understanding corporate social responsibility (CSR) tends to be contextually bound, and should be divorced from the mechanistic Western perspective prevailing in most extant literature. Despite this context-specific notion to CSR relevance, there is still an overwhelming dominance of the understanding of CSR from the Western perspective, so companies should more closely consider local issues when drawing up CSR policy guidelines in a non-Western environment.
Originality/value
Forty-eight individuals in the Niger Delta region have been interviewed, and their opinions on CSR issues have been reported.

Abstract
This is a case study about the green agenda of Urban Hijau, a social enterprise which promotes urban farming as a way to a foster sustainability. It narrates how it started and progressed through the introduction of various sustainable farming systems. The landscape of farming with its opportunities and challenges such as embracing permaculture as a farming philosophy, and food security are presented. The case ends with questions which Urban Hijau has to address in order to sustain its social enterprise. Can a small urban farm contribute significantly to the food industry? If so, how? Is Urban Hijau on the right track?

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract
AS A RESULT of present economic problems in Britain and attendant cuts in spending, there is a need to achieve maximum cost‐effectiveness in all sectors of public spending including libraries. This article examines a simple method by which economies could be made in buying multiple copies of books. It is assumed that unless librarians have freedom to buy a single copy of any book they choose, they will not achieve the breadth and depth required of first‐class libraries, be they in the public sector or in academic institutions. Perhaps second copies need cause little concern, but a pilot survey of a polytechnic library revealed cases where as many as four, six or even eight copies of the same edition had been bought on one occasion before the effectiveness of a lesser purchase could have been evaluated.
NOT before time, the future task that lies before industry has been spelled out for us at the various political conferences that have taken place over the past two months.

Abstract
Within both Western and Eastern traditions of virtue ethics, there is a Doctrine of the Mean, suggesting that errors may lie either in excess or in deficiency. The need to avoid both excess and deficiency in the allocation of finite resources is a concern in many sorts of business decisions, some with ethical implications. One finite resource is the resource of attention, and ethical problems can arise from failures to attend to important things. Both Aristotle and classical Confucianism accept the importance of paying attention to circumstances rather than following fixed rules or blindly maximising value. For organisations to give appropriate attention to different things requires suitable intra-organisational reporting and communication. Then there is still need for awareness that resources are finite, and for activity that is sustainable, highlighting the related idea of harmony, especially salient in the Confucian tradition.
