This paper aims to describe the use of optimization approaches to increase the range of near-future howitzer ammunition.

The performance of a gliding projectile concept is assessed using an aeroballistic workflow, comprising aerodynamic characterization and flight trajectory computation. First, a single-objective optimization is run with genetic algorithms to find the maximal attainable range for this type of projectile. Then, a multi-objective formulation of the problem is proposed to consider the compromise between range and time of flight. Finally, the aerodynamic model used for the gliding ammunition is evaluated, in comparison with direct computational fluid dynamics (CFD) computations.

Applying single-objective range maximization results in a great improvement of the reachable distance of the projectile, at the expense of the flight duration. Therefore, a multi-objective optimization is implemented in a second time, to search sets of parameters resulting in an optimal compromise between fire range and flight time. The resulting Pareto front can be directly interpreted and has the advantage of being useful for tactical decisions.

The main limitation of the work concerns the aerodynamic model of the gliding ammunition, which was initially proposed as an alternative to reduce significantly the computational cost of aerodynamic characterization and enable optimizations. When compared with direct CFD computations, this method appears to induce an overestimation of the range. This suggests future evolution to improve the accuracy of this approach.

To the best of the authors’ knowledge, this paper presents an original ammunition concept for howitzers, aiming at extending the range of fire by using lifting surfaces and guidance. In addition, optimization techniques are used to improve the range of such projectile configuration.

This study has two objectives:(1) to examine impacts of environmental activity, relational marketing, and corporate green image on firm’s competitive performance; and (2) to determine whether relational marketing and corporate green image mediate relationships between environmental activity and firm’s competitive performance. They were data from 375 small and medium enterprises (SMEs) of the food processing industry in Bangkok, Thailand. This study also investigates the relationships between environmental activity, green corporate image, relational marketing, and influences of these factors on firm’s competitive performance. Structural equation modeling (SEM) was used to analyze data. Results reveal significant and positive relationships between environmental activity, green corporate image, relational marketing, and firm’s competitive performance. Moreover, environmental activity, an antecedent variable, indirectly affects a firm’s competitive performance mediated by green corporate image and relational marketing. Therefore, green corporate image and relational marketing can act as mediators between environmental activity and firm’s competitive performance. Findings suggested that firms should focus on improving green corporate image and relational marketing with an appropriate environmental activity strategy to enhance the firm’s competitive performance. Moreover, this study’s result is related to the economics of the environment in terms of cost and benefit. It provides firm’s decision on environmental activity.

Micro and small enterprises (MSEs) represent 99% of Peruvian firms, contribute 42% of Peru's Gross Domestic Product, and employ half of the country's labor force. Despite their relevance for the Peruvian Economy, they have low survival rates and are characterized by low productivity and processes inefficiencies. This chapter explores whether the adoption of Business and Supply Chain Management (SCM) practices influences MSEs' performance. We conducted a field study using data from 50 MSEs located in Piura, Peru, specifically from trade, service, and manufacturing sectors. We used the data collection guidelines from the MIT GeneSys to measure the firms' adoption of Business and SCM practices. Our results show that MSEs with higher adoption of Financial Planning, Supply Chain Planning, Supplier Relationship Management, Marketing, Procurement, and Stock Control practices are more likely to have higher revenue (i.e., sales). In addition, a multiple regression analysis reveals that while SCM practices do not seem to directly explain productivity growth in MSEs (as business practices do), they, however, seem to influence the performance of business practices, and, thus, have an indirect effect on the productivity growth of MSEs.

The field of Supply Chain Management (SCM) has mainly focused on applications for large firms, where significant amount of theory has been developed in the last decades. Little attention has been received by micro and small enterprises (MSEs) that in Latin America represent approximately 99% of all businesses and are the key for the development of the economy, employment, and growth of the region. Due to MSEs' lack of productivity, only a fraction of them survive and thus contribute to Latin America's economic growth. In this chapter, we discuss the connection between MSEs' productivity growth and SCM. We present key takeaways from the literature and summarized different research approaches used to study this emerging field, specifically related to the impact of the size of the company, the use of surveys to gather data, and the importance of field interventions. We also present a large-scale project (i.e., MIT GeneSys) that focuses on improving survival of MSEs in developing countries and discuss some preliminary learnings gained via conducting shadowing/immersion of ∼250 MSEs from Mexico, Colombia, Chile, Ecuador, Peru, and Bolivia. We conclude the chapter by presenting some recommendations for the future research agenda for the emerging field of SCM for MSEs in Latin America.

The purpose of this paper is to review the concept of perceived service quality in the fitness industry by considering the service-dominant logic (Vargo and Lusch, 2004) and examining existing service quality models in the context of sport and fitness.

The paper critically reviews generic and industry-specific models of service quality in the fitness industry. The examination of the models is intended to identify the role that the perspective of customers and the dynamics of service co-creation play in these models.

Consideration of the context in a particular industry plays an important role in the development of service quality models. If underestimated, it can result in a model being inadequate or having limited explanatory potential. The review shows that both generic and fitness industry-specific models have methodological and conceptual limitations. This requires researchers to consider developing new contextual models that acknowledge service as co-creation of experience/value between suppliers and customers; and the goal of this co-creation as fulfilment of customers’ aspirations. Such an approach brings a new light to the meaning of “a customer’s perspective” and emphasises the dynamics of service co-creation in the fitness industry.

The study provides an agenda for future research to consider perceived service quality models from the customers’ perspective. It suggests researchers to take into account various factors of consumer behaviour (e.g. motivation) which are unique to sport and fitness services. Also, managers of fitness facilities need to revisit their tools for capturing customers’ perceptions and to update the areas included in customer satisfaction surveys.

The paper provides an insight into the role of co-creation for service quality in fitness services. It contributes towards establishing revised relations between service quality in fitness and contextual industry-specific factors suggested by numerous studies previously.

On a global scale, leadership takes place within a complex environment that is molded both by national culture and organizational culture influences. This chapter explores leader-culture (L-C) fit in this global context. Drawing together distinct perspectives on national culture and organizational culture, we identify potential contingencies of L-C fit across these levels. In addition to identifying key gaps and areas for future exploration, we also discuss the practical uses of fit when selecting and developing leaders. Overall, we argue that researchers and practitioners could benefit from an expanded perspective on cultural fit to simultaneously address aspects of national and organizational culture.

The authors propose that the nature of prejudice differs across cultures. A model is introduced that proposes that the interpersonal perspective associated with individualist cultures (Westerners) leads to interpersonal prejudices, whereas the intergroup perspective associated with collectivist cultures (Easterners) leads to intergroup prejudices. These prejudices, in turn, are argued to impact on the outcomes of individuals working in intercultural teams. An organisational diversity climate of openness fostered by diversity oriented HRM and the combined use of individualist and collectivist HRM policies and practices is proposed to minimize the negative effects of such prejudices can be minimized.
