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.

In this chapter, we focus on expatriate CEOs who are assigned by the parent company to work in a subsidiary and compare them to those who themselves have initiated to work abroad as CEOs. Since we do not know much about these individuals, we direct our attention to: (1) who they are (demographics), (2) what they are like (personality), and (3) how they perform (job performance).

Data was sought from 93 assigned expatriate CEOs and 94 self-initiated expatriate CEOs in China.

Our findings demonstrate that in terms of demography, self-initiated CEOs were more experienced than assigned CEOs. With regard to personality, we found difference in self-control and dispositional anger: Assigned expatriate CEOs had more self-control and less angry temperament than their self-initiated counterparts. Finally, we found assigned expatriate CEOs to rate their job performance higher than self-initiated CEOs.

Although there may not always be immediate benefits, career consideration often plays a role when individuals choose whether to become an expatriate. For many years, organizations have used expatriation to develop talented managers for high-level positions in the home country. Recently, however, a new trend has emerged. Talented top managers are no longer expatriated only from within parent companies to subsidiaries. Self-initiated expatriates with no prior affiliation in the parent company are increasingly used to fill top management positions in subsidiaries.

Supply chains (SCs) have become increasingly vulnerable to catastrophic events/disruptions that may be natural or man-made. Hurricanes, tsunamis and floods are natural disasters, whereas man-made disasters may be strikes, terrorist attacks, etc. Failure at any point in the SC network has the potential to cause the entire network to fail. SCs must therefore be properly designed to survive well in the disruption scenario. The capability of successful survival (of the firm’s SC) against those adverse events/happenings is termed as resilience; and, the SC designed under resilience consideration is called a resilient SC. Effective supplier selection is considered as a key strategic consideration in SC management. It is felt that apart from considering traditional suppliers selection criterions, suppliers’ resiliency strategy must be incorporated while selecting a potential supplier which can provide best support to the firm even in the disaster/disruption scenario. The purpose of this paper is to focus aspects of evaluation and selection of resilience supplier by considering general as well as resiliency strategy, simultaneously.

In this work, subjectivity associated with ill-defined (vague) evaluation information has been tackled through logical exploration of fuzzy numbers set theory. Application of VIKOR embedded with fuzzy mathematics has been utilized here. Sensitivity analysis has been performed to reflect the effect of decision-makers’ (DM) risk bearing attitude in selecting the best potential supplier in a resilient SC. A case empirical example has also been presented.

The work attempts to focus on a decision-making procedural hierarchy towards effective supplier selection in a resilient SC. The work exhibits application potential of VIKOR method integrated with fuzzy set theory to select potential supplier based on general strategy as well as resiliency strategy. The final supplier selection score (obtained by considering general strategy) and that of obtained by analyzing resiliency strategy have been combined to get a final compromise solution. The decision-support framework thus reported here also considers DMs’ risk bearing attitude.

The study bears significant impact to the industry managers who are trying to adapt resiliency strategy in their SC followed by potential supplier selection in the context of resilient SC.

Exploration of VIKOR embedded with fuzzy set theory towards suppliers’ evaluation and selection by considering general and resiliency criteria both. The decision-support module(s) adapted in this paper considers DMs’ risk bearing attitude to arrive the best compromise solution.

Earlier studies on employee turnover have invested enormous scholarly mileage to understand and address human resource challenges. Considering the substantial evidence on the negative and non-linear relationship between employee turnover and firms’ performance, the purpose of this study is to investigate the effects of employee turnover on the social outreach (e.g. breadth of outreach) of microfinance institutions (MFIs), also known as the financial inclusion agenda of the Sustainable Development Goals.

To achieve the study objective, the authors collected unbalanced panel data of 1,391 MFIs, covering a total of 96 economies and a period of 2010–2018. The organizational and macroeconomic data were obtained from the World Bank’s Mix Market and World Development Indicators databases, respectively, and subsequently analysed using the pooled ordinary least squares, random effects model, fixed effects model and generalized method of moments.

Overall, the authors found that employee turnover has a positive impact on the social outreach of MFIs, which suggests that employee turnover reduces organizational blindness and groupthink, potentiates efficiency gains and minimizes retention costs. On the contrary, this study does not find evidence of a non-linear effect of employee turnover on the outreach objectives of MFIs. Meanwhile, these effects were observed to vary depending on the proxy, sub-samples and techniques used in the analysis.

Motivated by the paucity of literature, the study has uniquely investigated the effect of employee turnover on the social outreach objective of MFIs by using relatively recent and global-level data. The study findings can help managers and the human resource departments to make optimum decisions about employee turnover management.

This paper aims to explore the level of hibah knowledge among Muslims in Kedah and investigate its determinants, consisting of education level, education stream, religiosity, social influence and social media.

This study is quantitative in nature. Questionnaires were distributed to collect data from Muslims in Alor Setar, Kedah. In total, 195 questionnaires were collected and data were analyzed using descriptive analysis, correlation analysis and multiple regression analysis.

The study finds that Muslims in Alor Setar, Kedah have good knowledge of hibah. Further, education stream, religiosity, social influence and social media were identified as significant factors that influence their knowledge of hibah.

The first limitation is its narrow focus in surveying Muslims only in Alor Setar, Kedah. The second limitation is the limited number of determinants used in investigating hibah knowledge among Muslims and the techniques used in analyzing the data. Despite these limitations, the study’s findings provide invaluable insights into the factors influencing hibah knowledge among Muslims in Alor Setar, Kedah.

This study provides insights regarding the significant personal factors and environmental factors to increase Muslims’ knowledge of hibah. The link between the Islamic education stream and hibah knowledge provides a clear indication that Islamic education can curb the economic problems caused by the substantial amounts of frozen and unclaimed assets in Malaysia. A significant relationship between the environmental factors (social influence and social media) and hibah knowledge also implies that the government and private agencies related to Islamic estate planning and management may use these significant determinants as part of the marketing strategy to increase the usage of hibah as an alternative tool for estate planning.

This study contributes to a better understanding of Muslims’ knowledge about hibah. The government and related agencies in Islamic estate planning and management can now gain better insights into Muslims’ level of knowledge about hibah and the factors influencing their knowledge of hibah as an effective tool for Islamic estate planning and management. Hence, more effective strategies can be recommended to enhance the knowledge of Muslims on hibah. The findings of this study should be of value to the government in its effort to address the increasing number of frozen estates in Malaysia.

This study aims to provide descriptive analysis on urbanization pattern in Sukoharjo Regency and also its correlation to land use and cover change (LUCC) issue. This becomes more relevant because the authors find that there are few studies conducted regarding the topic. Consider again the importance role of Sukoharjo Regency as an area that provides supporting food supply, LUCC particularly in agriculture land became even more crucial.

This study uses literature reviews and descriptive analysis. Data for this study are obtained from previous studies and statistical data from Central Statistical Bureau.

Sukoharjo Regency proved as an interesting migration destination for some group of population. The population group particularly come from Surakarta city (growth core) as a form of urban sprawl or urban expansion. Migrant population live in Sukoharjo Regency are mostly a population group with a productive age range and generally with high-school or vocational school level. Moreover, their main reason to migrate is the availability of job opportunities. Regarding LUCC, migrant populations that come to Sukoharjo Regency apparently have property with ownership certification. Housing area development, particularly concentrated in the district, was located close to the borderline Surakarta city.

This research contributes to the analysis of land use change trends in peri-urban areas caused by migration. The results of this study can be used for further policy making to overcome the dilemma of land use change, especially those that occur on agricultural land.

Islamic home financing products with Murabaha contracts are widely favored among the Muslim community in Indonesia, given that the country has a population of over 230 million Muslims. To facilitate the development of products and enhance public interest, it is important for Islamic banking institutions to comprehend the elements that may impact the intents of Muslim communities in Indonesia when selecting Islamic home financing products with Murabaha contracts. The purpose of this study is to ascertain the many aspects that may have an impact on the decision-making process of Muslim communities in Indonesia when selecting Islamic home financing product that use Murabaha contracts.

The partial least square-structural equation modeling data processing techniques will be used to process and evaluate these components. The data used in this study was acquired by administering questionnaires to a sample of 298 Muslim communities, which were randomly selected from a pool of 301 possible customers of Islamic house finance in Indonesia.

The results of this research show that attitude, subjective norms and perceived behavioral control have positive influence on intention to choose an Islamic home financing scheme with Murabaha agreement, while price fairness of Islamic home financing and Islamic altruism have direct and indirect influence on intention to choose Islamic home financing.

Analyzing factors that affect intention to choose Islamic home financing product under Murabaha contract is essential. Future study is required to analyze other Islamic home financing products, such as istisna, ijarah muntahia bi tamlik and diminishing musharakah. This study only serves as a foundation for further investigations into conventional approaches to home financing in emerging nations. The areas can be expanded to be implemented in other countries.

It is anticipated that Islamic banks have the capacity to cultivate a favorable and constructive perception, hence fostering a positive disposition among the Muslim populace in Indonesia. Furthermore, it is essential for Islamic banks to guarantee that all stakeholders within the sharia-compliant institution, particularly the frontline staff, have enough expertise and understanding of the intricacies of Islamic home financing products including Murabaha contracts, which are intended for prospective customers. In the foreseeable future, it is anticipated that the Muslim population in Indonesia would exhibit a greater intention toward the use of Islamic home financing solutions that use Murabaha contracts, facilitated by the establishment of a conducive environment.

This research integrates the impacts of pricing fairness and Islamic charity as a modified model, alongside the theory of planned behavior model, to examine the influence of these factors on individuals’ intentions to use Islamic home financing in Indonesia.

This study aims to investigate the direct effect of directors’ age diversity, and its interaction effect with the effectiveness of TMT meetings on bank performance.

Quantitative data were extracted from the bank’s annual reports for the six years 2011–2016. Age diversity was calculated using the coefficient of variation, and the bank’s performance was measured as return on assets and return on equity. The frequency of directors’ meetings was used as a proxy for the effectiveness of TMT meetings.

Based on the hierarchical regression analysis, the results do not support the hypothesis that there is a negative influence between age diversity on performance. However, the results support the hypothesis that age diversity has a positive effect on performance because of the high effectiveness of TMT meetings.

The limitations of the study include the use of only samples of the banks registered with Bank Indonesia. The subsequent research could use cross-country bank samples. In addition, the research uses age-related diversity variables only. Therefore, further research could consider other types of diversity such as education, functional or tenure. Furthermore, this study is limited to the effectiveness of the director (TMT) meetings as the only moderating variable. Further research could improve on this by including other moderating variables.

The findings of this study indicate that the existence of age diversity in TMT will aid bank governance if it is accompanied by effective meetings among groups of directors of varying ages. This age composition of directors will make meetings more effective as rich information for strategic decisions will be generated from different points of view because of the wide spectrum of age categories, and hence, there will be a positive impact on bank performance.

This study indicates that effective meetings of TMT groups of different ages will minimize the rise of “self-esteem”. Therefore, they will benefit the creation of a better quality relationship among TMT individuals. Accordingly, TMT within a company will have more opportunities to discuss in providing bright ideas for the company on how to innovate and create a new strategy to improve its performance.

This study, being the first to explore the effectiveness of TMT meetings to bank performance in the contexts of directors’ age diversity, contributes to the literature in this area, and especially to the body of knowledge about companies implementing a two-tier governance system.

National Health and Morbidity Survey of Malaysia 2011 revealed that hypercholesterolemia (35.1 per cent, 6.2 million) was the primary leading causes of cardiovascular disease in Malaysia. Currently, three established recommended approaches such as therapeutic lifestyle change (TLC) diet, pharmacotherapy (simvastatin) and TLC + simvastatin are available to the public but, to our knowledge, have never been compared in Malaysia Primary Health Care setting. Hence, this paper aims to compare the lipid lowering effects of these three approaches in a primary health care clinic.

This randomized trial enrolled 180 patients with hypercholesterolemia who met adult treatment panel III (ATP III) criteria. All participants were randomized to TLC diet, simvastatin (10-20 mg/d) or TLC + simvastatin diets. The TLC group was enrolled in a 12-week multidisciplinary lifestyle program that involved monthly 45 minutes to hour meetings. The simvastatin group received medication, and traditional counseling was conducted by registered medical officer. Another group was enrolled into TLC + simvastain treatment. The primary outcome measure was the percentage change in low-density lipoprotein-cholesterol. Secondary measures were changes in weight loss, blood pressure and dietary changes. Assessments were repeated at three-month interval.

Lifestyle changes combined with simvastatin had a better lipid lowering effect compared to the other two treatments. However, TLC had a better weight and blood pressure reduction compared to the other two treatments. Nevertheless, TLC group showed reduction proportions similar to standard therapy with simvastatin or TLC + simvastatin. TLC has proven as an alternative approach to hyperlipidemia for a subset of patients unwilling or unable to take statins especially in a community-based, primary health care setting.

Weight loss was not recorded for simvastatin participants, and this was the major drawback of this study, and there was no comparable weight loss reduction with other groups.

In Malaysia, the efficacy of hypocholesterolemic therapies among patients who are receiving the most common lipid-lowering drug, simvastatin, in primary health care setting has not been clearly defined. There is also a lack of research on the efficacy of TLC conducted by registered dietitian in a primary health care setting in Malaysia.

The purpose of this study is to examine the effect of Board of Directors Effectiveness (BODE) on the performance of Malaysian Takaful companies licensed by the Central Bank of Malaysia. In addition, the study investigates the moderating effect of Shariah Committee Quality (SCQ) on the relationship between BODE and companies’ performance.

This study uses a sample of 11 Malaysian Takaful companies during the period of 2010-2017. While BDE and SCQ are measured using indices, performance is proxied using ROA and ROE. A panel fixed effect regression analysis is used to test the impact of the BDE on the financial performance of Malaysian Takaful companies and the moderator role of SCQ.

The main finding of this study shows a positive association between BDE and performance. More specifically, boards with a high presence of independent, Muslim and female directors positively contribute to the performance of Malaysian Takaful companies. Another interesting finding is related to the positive moderating effect of SCQ on the relationship between BDE and performance. This result indicates that a high level of SCQ combined with a high level of board effectiveness improve performance.

The finding is of great importance to stakeholders and policymakers to improve their board effectiveness and the quality of the Shariah committee to reduce agency costs and to improve the performance of Malaysian Takaful companies.

This study adds to the prior literature by investigating for the first time the relationship between BDE and performance and the interaction effect of SCQ on the performance of Malaysian Takaful companies.
