This chapter examines the effect of the division of labor from a Bayesian viewpoint. While organizational reforms are crucial for cost reduction in the Japanese water supply industry, the effect of labor division in intra-organizational units on total costs has, to the best of our knowledge, not been examined empirically. Fortunately, a one-time survey of 79 Japanese water suppliers conducted in 2010 enables us to examine the effect. To examine this problem, a cost stochastic frontier model with endogenous regressors is considered in a cross-sectional setting, because the cost and the division of labor are regarded as simultaneously determined factors. From the empirical analysis, we obtain the following results: (1) total costs rise when the level of labor division becomes high; (2) ignoring the endogeneity leads to the underestimation of the impact of labor division on total costs; and (3) the estimation bias on inefficiency can be mitigated for relatively efficient organizations by including the labor division variable in the model, while the bias for relatively inefficient organizations needs to be controlled by considering its endogeneity. In summary, our results indicate that integration of internal sections is better than specialization in terms of costs for Japanese water supply organizations.

The purpose of this study is to use an empirical model to investigate the effects of eight types of shareholders on corporate social responsibility (CSR) investments in terms of the monetary amount and ratio of each investment.

Cross‐sectional data obtained from Japanese companies in 2010 were used and three equations were estimated which reflect the effects of various shareholders on three types of CSR using ordinary least squares (OLS).

The study finds that the effects of shareholders on CSR investment are different depending on shareholder types. Investment funds and top management shareholders decrease each CSR investment, while the government, foreign companies and individuals, financial institutions, brokerages, and domestic companies and individuals increase CSR investments. Moreover, different shareholder types are interested in different CSR. Most shareholders are concerned with environmental policies, while foreign shareholders are also concerned with work‐life balance policies. Investment funds shareholders pay attention to all kinds of CSR. In addition, most outside shareholders are only concerned about individual CSR investments rather than a company's entire CSR resource allocation strategy.

This study empirically analyzes various types of shareholders, determining which hypothesis is valid and what type of shareholder increases or decreases CSR investment. This study considers shareholders' effects not only on each CSR action, but also in terms of an overall CSR strategy. This study provides guidance for managers that they should take into account in order to respond to each type of shareholder when they make decisions on CSR.

This paper aims to investigate the following two research questions: Do corporate social responsibility (CSR) investments enhance a firm’s economic performance? Does the firm’s economic performance influence CSR investments? That is, the bidirectional relationship between CSR investments and economic performance.

This paper analyzes three types of CSR investments (environmental, labor-related and social investments) using a simultaneous equations model with a data set of 185 Japanese firms.

Environmental investments reduce economic performance, labor-related investments do not significantly affect economic performance and social investments increase economic performance. Moreover, strong economic performance decreases environmental investments but increases social investments. Labor-related investments are chosen considering economic performance in both the present and previous terms.

For managers, environmental and labor-related investments are not effective for improving economic performance. However, eradicating them completely might harm corporate reputation. In contrast, social investments have now become important. For policymakers, different approaches may be adopted to encourage firms to increase CSR investments. In some cases, policymakers can rely on firm initiatives instead of regulating or encouraging CSR activities.

First, the authors empirically examine the bidirectional relationship between CSR investments and economic performance. Second, they clarify the determinants of CSR by specifying the investment function of each type of CSR. Third, they consider three types of CSR investments, with interrelations among them allowed in the model, and determine how each type affects firm performance.

This paper aims to determine the best conventional degumming technique for use by rural farmers practicing Eri silk fiber production in Kenya.

Three conventional silk degumming methods (water, soap and alkali) were analyzed under the factors, namely, time, pressure and degumming media, following the multilevel factorial design of experiments. The effect of variables on degumming weight loss was determined. The effects of the conventional degumming methods that produced complete sericin removal on chemical structure, surface morphology, thermal properties, crystallinity and fiber strength on Eri silk fibers produced in Kenya were then determined. The optimal degumming condition was then evaluated.

Soap and water degumming led to incomplete sericin removal. Alkali degumming media had the most effect, especially when pressure cooked at 103 kPa. Increasing time during alkali degumming beyond 30 min did not to have any major difference on degumming loss (at p 0.05). There were no major changes in chemical and thermal properties after degumming. However, the tensile strength and elongation deteriorated especially on alkali medium. Decreasing degumming time in alkali medium from 120 min to 30 min reduced the strength loss from 45% to 33%. Optimal degumming was found to be in an alkali media at 103 kPa for 30 min.

There is very little information available on Eri silk fibers produced in Kenya. Results of this study provide an optimized conventional degumming procedure suitable for small scale farmers in rural areas practicing Eri silk fiber production.

The essence of Japanese culture is said to lie in the group rather than in the individual. According to the viewpoint favoured in most writings on Japanese society and culture, the Japanese are a group‐oriented people; they like to work in groups and have always worked in association with one another, and social pressures on the individual to conform happen to be irresistible. The nail that sticks out, as the popular saying goes, gets hammered down.

This study aims to understand how the institutional and populational characteristics of a Brazilian city, that is, size, gross domestic product (GDP), life expectancy, education, violence and amount of workers benefiting from PAT (Workers’ Food Program) bias the agglomeration of fast-food companies.

The research involved 7,653 units distributed among 270 brands of fast-food chains (9 foreign and 261 Brazilian) operating in 542 Brazilian cities in 2015 and institutional and populational characteristics information about them. It calculated the Herfindahl index and implemented mixed inflated beta models.

The study found out that the agglomeration of establishments is mainly associated with the city’s income per capita, education, GDP and with some differences regarding the origin of the company, Brazilian or foreign.

The limitations of the study are the availability of Brazilian cities' data and information about the fast-food companies, such as governance-related information and general infrastructure. The study was cross-sectional, which does not analyze the business installation speed.

This work provides data collection and analyzes which factors may contribute to the knowledge of the Brazilian fast-food market. It stands out that foreign companies do not seem to contemplate city violence. The proposed models can serve as an investors’ foundation to start, expand business and predict the number of establishments in a city.

The study highlights the relation between the cities’ institutional and populational characteristics and the aggregation of fast-food chains in Brazilian cities, using index commonly applied in industrial agglomeration.

This study aims to investigate the impacts of procurement strategies on the growing proportion of construction small- and medium-sized enterprises (SMEs) and whether the size of the construction company moderates the effect.

This study adopted a quantitative research approach and a cross-sectional questionnaire survey in achieving its objectives. The survey requires the respondent to identify both the most successful and most outstanding project that the respondent was involved in between 2010 and 2016.

The study found that only traditional and management-oriented procurement strategies ensure the achievement of all growth plans for construction SMEs in South Africa; and that medium-sized construction enterprises achieve social growth such as community empowerment, managerial skills and advancement on the cidb Register of Contractors.

The findings of the study imply that policymakers should base their decisions regarding macroeconomic issues and growth plans for construction SMEs on the internal and external factors such as differences in the sizes of construction SMEs and differences in the suitability of procurement strategies affecting the growth of construction SMEs.

In past studies, the diversity amongst SMEs is often overlooked and SMEs are erroneously assumed to share similar objectives, possess equal capabilities and face challenges of the same magnitude. The original contribution of this study is shown in the investigation of the moderating effect of SMEs’ diversity (in terms of company size) on their growth proportion as influenced by procurement strategies.

WORDS, the currency of human thought, are easily debased. Frequent repetition can empty them of serious meaning. Rightly used they can, with the brevity and directness of a road sign, provide the pith of a subject. Only when they are widely adopted and used as a label to stick on every package do they lose significance.

Burnout is defined as the syndrome that causes emotional exhaustion, depersonalisation and reduction in personal achievement, and concerns people-oriented professions. This study explores the impact of burnout on the health, social and family life of mental health nurses.

A qualitative method with face-to-face semi-structured in-depth interviews was implemented with 16 mental health nurses working in Athens, Greece.

Nursing staff experience emotional exhaustion intensely due to stress since psychiatric patients require constant contact and communication and increased needs that workers have to meet. Regarding the feeling of personal achievement, they evaluated their performance positively and were satisfied with the effectiveness of the care provided. Regarding depersonalisation, the interviewees stated that they do experience it; however, in their majority they express that they do not wish to distance themselves from their duties. Their social and family life is not significantly affected and communication and support from family members is highly rated.

The research has focused on samples of nurses without mentioning their specialisation, while few studies in Greece have focused on the phenomenon in mental health nurses using qualitative research methods. This study aimed to fill this gap in the literature by examining burnout syndrome using a qualitative methodology.
