This paper sets out to examine the reasons why 599 entrepreneurs in Kenya, Ghana and Nigeria started their small businesses. It aims to compares ten motivations across three countries and by gender.

Ten Likert‐style questions were used to determine start‐up motivations. The mean scores were calculated and compared to test for significant differences. A factor analysis was conducted to see whether the ten items could be synthesized into distinct factors. Then, the factors were compared across countries and by gender.

The strongest motivator across countries was the opportunity to increase income. A factor analysis found three motivation factors: a family factor, an external validation factor, and a self‐betterment factor. The three countries showed significant differences with Ghanaian entrepreneurs rating the family factor as more important. The item analysis showed that female entrepreneurs were less motivated to create a business as a legacy or for external validation.

The list of motivations here is non‐exhaustive. The addition of other motivation items could change the results. Results should not be generalized to other countries or other regions of the countries surveyed.

Since motivations differ across countries and gender, countries can benefit from developing country‐ and gender‐specific programs to encourage business creation. For instance, Nigeria and Kenya should develop stronger succession laws so that businesses can be inherited by family members. Ghana and Nigeria might stimulate more enterprise development by providing public recognition for entrepreneurial behavior.

This is the first cross‐country study of the motivations of entrepreneurs in sub‐Saharan Africa.

This article aims to investigate motivations, success factors, problems, and business‐related stress of entrepreneurs in small‐ and medium‐sized enterprises and relates them to the success of the Chinese entrepreneurs.

A total of 196 entrepreneurs in Beijing, Shanghai, and Guangzhou were randomly selected for a survey, which was analyzed to determine motivations, success factors, problems, and business‐related stress by gender. Ordered logit models were applied to motivation and success factors.

Results showed that 68 percent were male and 32 percent female. The average age of the entrepreneurs was about 32 years old and time devoted to their business was almost 45 hours per week. Of the total respondents, 56 percent were married and 44 percent single. When asked to indicate their motives for business ownership, these entrepreneurs suggested that increasing income, becoming their own boss, and to prove that they can succeed were the most important reasons. Reputation for honesty, providing good customer services, and having good management skills were reported to be necessary conditions for business success. Friendliness to customers and hard work were also critical for high‐performance enterprises. Among the problems encountered by entrepreneurs, unreliable/undependable employees were the most critical. Intense competition and lack of management training also proved to be great challenges for Chinese entrepreneurs.

Policy makers can strengthen its small business entrepreneurs by promoting the factors that lead to entrepreneurs' success, such as the ability to manage personnel and management skills through business outreach services provided by universities, government agencies, and nonprofit organizations. In addition, the government has the ability to simplify the tax system, and reduce payroll taxes. Technical assistance in areas such as market research, human resources management, and technological support should be provided to small business owners.

This study applied to Chinese entrepreneurs in addition to an extensive analysis of the factors that affect motivations, success, problems, and business stress.

Entrepreneurship is lauded as an engine of economic development and job creation, with SMEs often creating most of the new jobs in many countries. This paper identifies some important factors that contribute to the start‐up and success of new business ventures in Africa, emphasizing that while personality factors such individual drive and competency and availability of resources are important for the successful launch of a new business venture, effective government policy is also critical in promoting successful entrepreneurial initiatives. Survey data collected showed that most African entrepreneurs believe that they have the requisite passion, energy, and determination needed to start and manage new businesses. However, they are constrained by scarcity of adequate start‐up capital, stiff competition, lack of employees with the right skills, and difficulty in finding adequate facilities to start their business. Building on this research and earlier work, the paper discusses the crucial role that African governments can play to stimulate and nurture entrepreneurial endeavours. While the findings and recommendations in this paper are based on the study of Ethiopian and Ghanaian entrepreneurs, they have applicability in several African countries. The actual implementation of the proposed recommendations will of course need to be adapted to suit the special circumstances prevailing in each country.

The purpose of this paper is to analyze the fuzzy reliability of the compressor house unit (CHU) system in a coal fired thermal power plant under vague environment by reducing the accumulating phenomenon of fuzziness and accelerating the computation process. This paper uses different fuzzy membership functions to quantify uncertainty and access the system reliability in terms of different fuzzy reliability indices having symmetric shapes.

This study analyses the fuzzy reliability of the CHU system in a coal fired thermal power plant using T_ω-based generalized fuzzy Lambda-Tau (TBGFLT) technique. This approach applies fault tree, Lambda-Tau method, different fuzzy membership functions and α-cut coupled T_ω-based approximate arithmetic operations to compute various reliability parameters (such as failure rate, repair time, mean time between failures, expected number of failures, availability and reliability) of the system. The effectiveness of TBGFLT technique has been demonstrated by comparing the results with results obtained from four different existing techniques. Moreover, this paper applies the extended Tanaka et al. (1983) approach to rank the critical components of the system when different membership functions are used.

The adopted TBGFLT technique in the present study improves the shortcomings of the existing approaches by reducing the accumulating phenomenon of fuzziness, accelerating the computation process and getting symmetric shapes for computed reliability parameters when different membership functions are used to quantify data uncertainty.

In existing fuzzy reliability techniques which are developed for repairable systems either triangular fuzzy numbers, triangle vague sets or triangle intuitionistic fuzzy sets have been used for quantifying uncertainty. These approaches do not examine the systems for components with different membership functions. The present study is an effort in this direction and evaluates the fuzzy reliability of the CHU system in a coal fired thermal power plant for components with different membership functions. This is the main contribution of the paper.

The definition of cycle time is the time from the wafer start to the wafer output. It usually takes one or two months to get the product since customer decides to produce it. The cycle time is a critical factor for customer satisfaction because it represents the response time to the market. Long cycle time reflects the ineffective investment for the capital. The cycle time is very important for foundry because long cycle time will cause customer unsatisfied and the order loss. Consequently, all of the foundries put lots of human source in the cycle time improvement. Usually, we make decisions based on the experience in the cycle time management. We have no mechanism or theory for cycle time management. We do work‐in‐process (WIP) management based on turn rate and standard WIP (STD WIP) set by experiences. But the experience didn’t mean the optimal solution, when the situation changed, the cycle time or the standard WIP will also be changed. The experience will not always be applicable. If we only have the experience and no mechanism, management will not be work out. After interview several foundry fab managers, all of the fab can’t reflect the situation. That is, all of them will have an impact period after product mix or utilization varied. In this study, we want to develop a formula for standard WIP and use statistical process control (SPC) concept to set WIP upper/lower limit level. When WIP exceed the limit level, it will trigger action plans to compensate WIP Profile. If WIP Profile balances, we don’t need too much WIP. So WIP level could be reduced and cycle time also could be reduced.

The issue of capacity constraint resources (CCR) or bottlenecks wandering in product mix decision by applying Theory of Constraints (TOC) management philosophy has been mentioned and demonstrated in several papers. In this study, the effect for prolonging the planning period (PPP) so as to stabilize the CCR is investigated. The results show that the effect for PPP alternative will be positive or negative which is depending on the environment condition. However, a majority cases which have positive effect for PPP alternative can be recognized prior knowing the marketing demand, which is significant in the real application.

The purpose of this paper is to test the dual frames of reference theory. For the test, the reference point hypothesis examines whether the difference in the quality of social conditions between the home and host countries determines the variations of immigrants’ trust in the institutions of their host country.

By using hierarchical linear modeling analysis, the current study examines whether “difference of homicide rate from South Korea” or “difference of level of democracy from South Korea” influences immigrants’ confidence in the police. Using data collected from nine different immigrant groups in South Korea, the current study examined both country-level factors as well as individual-level factors.

According to the analysis results, the difference of level of democracy from South Korea significantly influenced immigrants’ confidence in the South Korean police. Specifically, when immigrants came from democratically under-developed countries, they showed a relatively high level of confidence in the South Korean police.

Confidence in the police among the first generation of immigrants has recently attracted increasing attention. However, no previous studies have examined immigrants’ confidence in the police within an Asian country. Thus, the current study might contribute to generating better police performances toward first-generation immigrants who tend to be discriminated against and are also vulnerable to various forms of victimization because of their new status in a new society.

The purpose of this paper is to examine criminal offenders’ dispositional empathy and relate it to perceived parenting characteristics of primary caregivers (measured as care and overprotection) and inmates’ internal working models of the self and others (measured as attachment anxiety and avoidance, respectively).

Compared to a group of 110 college students, the group of 102 inmates indicated lower levels of cognitive and emotional empathy (measured as perspective taking (PT) and empathic concern (EC), respectively). Among inmates, perceived parental care was related to PT; parental overprotection was related to EC.

The inmates’ data fit a model suggesting a mediational role of attachment anxiety in the relation between perceived parental overprotection and EC. Also, inmates’ attachment avoidance moderated the relation between attachment anxiety and EC, so that the relation only occurred when attachment avoidance was not high. The findings suggested potential protective roles of early parental bonding and positive views of social others in enhancing empathy for justice-involved populations.

The findings shed light on how inmates’ perception of parenting related to both aspects of empathy and how cognitive representations of the self and others potentially underlie the association between perceived parenting and their disposition for EC. To cultivate dispositional empathy as a means of preventing delinquency, it is important to advocate not only parenting characterized as caring and warm, but also cognitive interventions on framing positive working models of social others, particularly for those who perceive their primary caregivers as overprotective and are highly avoidant to social closeness.

Each amusement park has a wayfinding system, while symbols are important mediums to guide tourists to find their destinations. It is very important that whether the meanings of symbols recognized by tourists immediately. This paper mainly discusses the recognition of graphic symbols in amusement park, and proposes the improvement suggestions. Materials for this study were drawn from 20 different graphic symbols of a theme amusement park in Taiwan. The testees were required to evaluate the design of graphic symbols based on symbolic meaning and graphics recognition to summarize the confusion matrix. The results show that there are three groups of graphic symbols easy to be confused, and five symbols not meeting a criterion of 67 per cent correct responses. The reasons were discussed, and improvement and relevant suggestions have been proposed, which may be helpful to redesign of symbols.
