Abstract

Purpose

The purpose of this paper is to investigate the impact that several of these factors have on a consumer’s decision to hold a credit card, as well as those involved in determining the level of credit card limit.

Design/methodology/approach

Potential explanatory variables were identified in the literature, then used to build a binary logit model to test the impact of the card and consumer characteristics on credit card ownership. Data were collected via a structured interview of 409 consumers living in Hebei Province, China.

Findings

The results indicate that convenience in use, level of credit card interest rates, the application process, number of people in the household, a rewards programme, marital status, credit limit and age influence the likelihood of the respondent holding a credit card. Further, an anaylsis shows that the number of credit cards held, duration of holding a credit card, monthly credit card purchasing volume and having a degree at the tertiary level, are significantly and positively related to different levels of credit limit.

Originality/value

In summary, in order to attract more consumers to credit card use, the banks and credit card companies should consider making it more convenient for consumers to use their credit cards. Moreover, banks can increase their networking and degree of cooperation with merchants to increase the acceptance of payment by credit card. The most heavily used businesses such as supermarkets and smaller retailers, where consumers purchase goods frequently, would be good targets for banks’ attention. In addition, banks might also improve credit card reward programmes to make these more efficient and perhaps increase the size of the rewards customers can earn through card use.

– The purpose of this paper is to identify factors affecting formal credit constraint status of rural farm households in Vietnam’s North Central Coast (NCC) region.

Abstract

Purpose

The purpose of this paper is to identify factors affecting formal credit constraint status of rural farm households in Vietnam’s North Central Coast (NCC) region.

Design/methodology/approach

Using the direct elicitation method (DEM), the authors consider both internal and external credit rationing.

Findings

Empirical evidences confirm the importance of household head’s age, gender and education to household’s likelihood of being credit constrained. In addition, households who have advantages in farm land size, labour resources and non-farm income are less likely to be credit constrained. Poor households are observed to remain restricted by formal credit institutions. Results from the endogenous switching regression model suggest that credit constraints negatively impact household’s consumption per capita and informal credit can act as a substitute to mitigate the negative influence of formal credit constraints.

Research limitations/implications

One limitation arises from the usage of the DEM to identify credit constrained households. The method cannot detect effective and ineffective constraints. Another limitation is the inability of cross-section data to capture long-term impacts of credit constraints on household welfare. Finally, causes of credit constraints from the lender’s view cannot be observed.

Practical implications

The results suggest that it is necessary to enhance the credit allocation regime to reduce the transaction cost and provide target households with sufficient credit. It should be emphasized that high transaction cost and the mismatch between credit demand and supply stemming from information asymmetry. The government can help formal financial institutions to reduce information cost by encouraging the active role of social organizations such as Women Unions, Youth Unions and Veteran Unions in bridging rural farm households with formal lenders.

Originality/value

There are limited studies focusing on determinants of credit constraints and their impacts on rural farm households. To the best of the knowledge, there is no study evaluating the impact of credit constraints on rural farm household welfare particularly in Vietnam. In addition, the studies related to credit constraints only considered full quantity rationing (households applied for the loan but were rejected), omitting the case of partly quantity rationing (loan obtained by the borrowers is less than their demand) and self-rationing.

Abstract

Purpose

Compliant mechanism has been receiving a great interest in precision engineering. However, analytical methods involving their behavior analysis is still a challenge because there are unclear kinematic behaviors. Especially, design optimization for compliant mechanisms becomes an important task when the problem is more and more complex. Therefore, the purpose of this study is to design a new hybrid computational method. The hybridized method is an integration of statistics, numerical method, computational intelligence and optimization.

Design/methodology/approach

A tensural bistable compliant mechanism is used to clarify the efficiency of the developed method. A pseudo model of the mechanism is designed and simulations are planned to retrieve the data sets. Main contributions of design variables are analyzed by analysis of variance to initialize several new populations. Next, objective functions are transformed into the desirability, which are inputs of the fuzzy inference system (FIS). The FIS modeling is aimed to initialize a single-combined objective function (SCOF). Subsequently, adaptive neuro-fuzzy inference system is developed to modeling a relation of the main geometrical parameters and the SCOF. Finally, the SCOF is maximized by lightning attachment procedure optimization algorithm to yield a global optimality.

Findings

The results prove that the present method is better than a combination of fuzzy logic and Taguchi. The present method is also superior to other algorithms by conducting non-parameter tests. The proposed computational method is a usefully systematic method that can be applied to compliant mechanisms with complex structures and multiple-constrained optimization problems.

Originality/value

The novelty of this work is to make a new approach by combining statistical techniques, numerical method, computational intelligence and metaheuristic algorithm. The feasibility of the method is capable of solving a multi-objective optimization problem for compliant mechanisms with nonlinear complexity.

Abstract

Purpose

Data crawling in e-commerce for market research often come with the risk of poor authenticity due to modification attacks. The purpose of this paper is to propose a novel data authentication model for such systems.

Design/methodology/approach

The data modification problem requires careful examinations in which the data are re-collected to verify their reliability by overlapping the two datasets. This approach is to use different anomaly detection techniques to determine which data are potential for frauds and to be re-collected. The paper also proposes a data selection model using their weights of importance in addition to anomaly detection. The target is to significantly reduce the amount of data in need of verification, but still guarantee that they achieve their high authenticity. Empirical experiments are conducted with real-world datasets to evaluate the efficiency of the proposed scheme.

Findings

The authors examine several techniques for detecting anomalies in the data of users and products, which give the accuracy of 80 per cent approximately. The integration with the weight selection model is also proved to be able to detect more than 80 per cent of the existing fraudulent ones while being careful not to accidentally include ones which are not, especially when the proportion of frauds is high.

Originality/value

With the rapid development of e-commerce fields, fraud detection on their data, as well as in Web crawling systems is new and necessary for research. This paper contributes a novel approach in crawling systems data authentication problem which has not been studied much.

Abstract

Purpose

The performance measure approach (PMA) is widely adopted for reliability analysis and reliability-based design optimization because of its robustness and efficiency compared to reliability index approach. However, it has been reported that PMA involves repeat evaluations of probabilistic constraints therefore it is prohibitively expensive for many large-scale applications. In order to overcome these disadvantages, the purpose of this paper is to propose an efficient PMA-based reliability analysis technique using radial basis function (RBF).

Design/methodology/approach

The RBF is adopted to approximate the implicit limit state functions in combination with latin hypercube sampling (LHS) strategy. The advanced mean value method is applied to obtain the most probable point (MPP) with the prescribed target reliability and corresponding probabilistic performance measure to improve analysis accuracy. A sequential framework is proposed to relocate the sampling center to the obtained MPP and reconstruct RBF until a criteria is satisfied.

Findings

The method is shown to be better in the computation time to the PMA based on the actual model. The analysis results of probabilistic performance measure are accurately close to the reference solution. Five numerical examples are presented to demonstrate the effectiveness of the proposed method.

Originality/value

The main contribution of this paper is to propose a new reliability analysis technique using reconstructed RBF approximate model. The originalities of this paper may lie in: investigating the PMA using metamodel techniques, using RBF instead of the other types of metamodels to deal with the low efficiency problem.

Abstract

Purpose

The purpose of this paper is to increase knowledge of the key drivers, and challenges, of the internationalization of Higher Education (HE), especially in the transitioning economy of Vietnam.

Design/methodology/approach

An exploratory qualitative research design used semi-structured interviews. Nine senior institutional leaders from five Vietnamese universities were interviewed. Thematic analysis, informed by the literature, was undertaken on English-translated transcripts.

Findings

The findings shared senior HE leader perspectives on how internationalization of HE in Vietnam was being conceptualized and operationalized, as well as insights as to how these processes might be improved. Further research to monitor the success of internationalization processes in Vietnam, and beyond, is recommended.

Research limitations/implications

This was an exploratory qualitative study including nine interviews with senior HE leaders from Vietnamese Universities. Exploratory findings only are shared.

Originality/value

No previous studies exploring internationalization of HE in Vietnam have been located. Vietnam is a nation in economic transition from a state-based to market-driven economy, and is different culturally, economically and socially, to its Asian neighbors. Internationalizing HE is considered essential to the global integration and development of Vietnam.

Abstract

Purpose

The purpose of this paper is to review both international and domestic (i.e. Vietnamese language) journal articles and graduate theses and dissertations on educational leadership in Vietnam. The review addresses two specific goals: first, to describe and critically assess the nature of the formal knowledge base on principal leadership in Vietnam, second, to synthesize findings from the existing literature on principal leadership in Vietnam.

Design/methodology/approach

The paper employed a method for conducting systematic reviews of research. The authors conducted a detailed, exhaustive search for international and “local” papers from Vietnam, yielding 120 research sources. Information from these papers was extracted and evaluated prior to analysis. Data analysis included both quantitative description of the “review database” as well as critical synthesis of substantive findings.

Findings

The review supports and extends an earlier review which found that the practice of educational leadership in Vietnam remains largely “invisible” to the international community of scholars. The review also yielded a highly critical assessment of research perspectives and methods used in the “local” Vietnamese studies which comprised the bulk of the authors’ database. Synthesis of substantive findings highlighted the manner by which organizational, political, and socio-cultural forces in the Vietnamese context shapes the practice of school leadership.

Research limitations/implications

First, qualitative studies are recommended that seek to describe, in-depth, the enactment of leadership in the Vietnamese context. Second, broad-scale surveys of characteristics, attitudes, and beliefs of school leaders across Vietnam are warranted. Third, the authors encourage graduate students and scholars studying school leadership in Vietnam to undertake a new generation of theory-informed studies that connect with the global literature.

Practical implications

Due to the relatively weak nature of the existing knowledge base, the authors were unable to identify specific implications for leadership practice. However, practical implications are identified for developing the research capacity needed to improve research quality in Vietnam’s universities.

Originality/value

This review is the first systematic review of educational leadership and management conducted of the Vietnamese literature. Moreover, the authors suggest that the review is original in its comprehensive coverage of both the local and international literature on educational leadership in Vietnam.

Abstract

This chapter describes how public sector reform (PSR) became important following the ‘Doi Moi’ (renovation) programme in 1986. Restructuring of state-owned sector was regarded as crucial for ensuring the quality of economic growth, and the Vietnamese government (www.chinhphu.vn/portal/page/portal/English) put considerable effort in PSR. The 8th Party Congress (1996) emphasized the urgent need for a more transparent, capable and modern public sector, including efforts to improve law-making process and capacity, reducing burdensome bureaucracy, fighting corruption, increasing leadership by senior officials and improving public service delivery. The government specifies the national PSR Master programme, and the Ministry of Home Affairs coordinates its implementation among ministries, central agencies and provincial governments. Local political leaders (party leaders) determine reforms based on guidelines of the party and government. The author writes that in spite of ambitious public service reform programmes and some positive achievements, the quality of public sector remains poor. The professional capacity of civil service is low, pay is low, corruption is high and processes and structures seem ill-fitted for the market economy. Reform scope is too broad, the capacity of public agencies and civil servants is limited and existing monitoring, evaluation and reporting systems are weak. In some successes, leaders use appointment and promotion to encourage lower level to implement reforms and training to increase understanding. They believe that Vietnamese leadership has become less proactive and vigorous in practicing or embracing bold reform experiments.

Abstract

Purpose

The purpose of this paper is to identify risk patterns of road and bridge projects in Vietnam, where the construction market is emerging but attractive to construction organizations, especially foreign companies.

Design/methodology/approach

Using a questionnaire, experienced practitioners of various contractors were interviewed to collect risk-related data in terms of actual likelihood and impact from road and bridge construction projects in Vietnam. Using the collected data of actual likelihood and impact, the specific probability and impact of risk factors were determined for different types of road and bridge projects, including small and medium type, big type, government-funding type, and other-funding type (e.g. official development assistance funds, public-private partnership).

Findings

The results of analysis indicate the specific probability and impact of risk factors in four risk themes, including contractor-related, project-related, owner-related, and external risks. Actual risk patterns for different types of road and bridge projects in Vietnam were identified.

Practical implications

The identification of actual risk patterns could help practitioners to know which risk factors are severe in frequency and/or impact. Hence, they could establish proper strategies to manage risk-related problems of road and bridge projects, in which they are directly involved.

Originality/value

The findings of this study could provide construction companies, especially foreign companies, with a better understanding of real risk panorama in Vietnamese road and bridge construction. Hence, they could make effective improvements on risk management of road and bridge projects in Vietnam.

The purpose of this paper is to investigate the determinants of the gender gap in the gross value of rice yield in Vietnam.

Abstract

Purpose

The purpose of this paper is to investigate the determinants of the gender gap in the gross value of rice yield in Vietnam.

Design/methodology/approach

A panel data set of 12 provinces of Vietnam from 2010 to 2014 was used, collected from the Vietnam access to resources household survey. To measure the gender gap in the gross value of rice yield, two-stage least squares and Blinder – Oaxaca decomposition methods were used.

Findings

The gross value of rice productivity of male-headed households was 10.3 percent higher than that of female-headed households. The gender gap in rice productivity is caused by the endowment and structural effects; the endowment effect explained 53 percent of the gender gap in rice productivity and the structural effect 42 percent.

Practical implications

In order to reduce the gender gap and improve the gross value of rice yield, the following policies are suggested: female education and access to institutional services (extension and credit) should be improved and future research is needed to determine the reasons for gender discrimination in the agricultural production system.

Originality/value

The findings suggest that the difference in the gross value of rice yield between male- and female-headed households were mainly caused by endowments and returns from those endowments.
