Abstract

Purpose

The purpose of this paper is to develop non-leaching and eco-friendly antimicrobial waterborne polyacrylates with excellent antibacterial properties by grafting antibacterial vinyl monomer, glycidyl methacrylate (GMA) modified polyhexamethylene guanidine hydrochloride (PHMG).

Design/methodology/approach

PHMG of different molecular weights were modified by GMA to synthesize antibacterial vinyl monomer, GMA-modified PHMG (GPHMG). Different content and molecular weights of GPHMG were used to synthesize antimicrobial waterborne polyacrylates through emulsion polymerization.

Findings

The addition of GPHMG gained by modifying PHMG showed little influence on thermal stability of the films, but decreased the glass transition temperature(Tg). Meanwhile, the tensile strength decreased, while the breaking elongation increased. The antibacterial properties of the antibacterial films with different GPHMG contents were studied, when GPHMG content was around 0.9 Wt.%, antibacterial films showed excellent antibacterial activity (antibacterial rate >= 99.99 per cent). When weight content of GPHMG in the films remained constant, antibacterial property of films increased first and then decreased with the increase of molecular weight of GPHMG. The structural antibacterial polymer film had more perdurable antibacterial activity than the blended one.

Research limitations/implications

The grafting efficiency of GPHMG to antimicrobial waterborne polyacrylates could be further improved.

Practical implications

Antimicrobial waterborne polyacrylates with excellent antibacterial properties can be used to antibacterial coating and adhesive.

Originality/value

The antibacterial properties of films with different molecular weight of GPHMG were studied, and the durability and stability of antibacterial properties between structural antimicrobial films and blended antimicrobial films were also investigated by ring-diffusion method.

Abstract

This chapter examines the similarities and differences between the concepts of transformational leadership as developed within North America and the Confucian idea of transformation. It argues that Confucian tradition encompasses the essential elements embedded in the concept of transformational leadership. The former differentiates from the latter in its deeper degree of transformation, emphasis on morality and culture, and its focus on transformation from the inside outwards. The two greatest educators in Chinese history, Confucius and Cai Yuanpei, are evaluated in terms of their transformational leadership qualities in the Western sense. By looking at Confucius and Cai Yuanpei as successful transformational leaders, the chapter identifies four important factors from Chinese cases that may contribute to the success of this type of leadership. Implications of this comparison are discussed as they may inform the knowledge, research and practices of transformational leadership.

This paper aims to investigate the thermal oxidation behavior of trimethylolpropane trioleate (TMPTO) base oil when exposed to Fe surfaces.

Abstract

Purpose

This paper aims to investigate the thermal oxidation behavior of trimethylolpropane trioleate (TMPTO) base oil when exposed to Fe surfaces.

Design/methodology/approach

Samples of TMPTO bulk oil were placed in Fe vessels and heated in an oven to accelerate the oxidation at different time intervals, while others were placed in glass vessels and used as experimental controls. Subsequently, the physicochemical properties of the oxidized TMPTOs, including the kinematic viscosity and acid value, were measured and a structural analysis was conducted using the Raman and Fourier transform infrared (FTIR) techniques.

Findings

The results demonstrate that the TMPTO bulk oil exhibited an exponential increase in the kinematic viscosity along with the increasing acid value over the oxidation time. The Fe surface significantly increased the kinematic viscosity of TMPTO, while only mildly impacting its acid value compared with the experimental controls. The structural analysis results of the TMPTO suggest that the C = C and = C-H bonds were the vulnerable sites. Furthermore, the results suggest that the Fe surface evidently accelerates the chemical reactions of the C = C and the = C-H bonds, and less alcohols and more carbonyl products were identified in the oil samples that were heated in the Fe vessels.

Originality/value

The results demonstrate that the Fe surfaces affected the oxidation behavior of the TMPTO base oil, and an interaction mechanism between the Fe and the TMPTO is developed.

Abstract

Purpose

This paper aims to examine the antecedent of purchase intention: online seller reputation, product category and surcharge.

Design/methodology/approach

This paper uses five experimental designs to explore the seller reputation, product category and surcharge effects in Internet shopping. The authors chose one seller of low reputation and one seller of high reputation from Yahoo Mall. ANOVA are used to evaluate the results.

Findings

Sellers of high reputation can post higher surcharges to increase the total price paid by the buyer, but sellers of low reputation cannot do so (experiment 1). Moreover, partitioned price will decrease purchase intention for sellers of low reputation more than for sellers of high reputation (experiment 2). Consumers take the longest time to make purchasing decisions when buying credence goods (experiment 3) or buying from sellers of low reputation (experiment 4). The effect of surcharge levied by sellers of low reputation is weakened for consumers with low (vs high) shipping‐charge skepticism (experiment 5).

Practical implications

This study is helpful to online sellers if they can identify their reputation, product category and those consumers who have shipping‐charge skepticism, they can create extra profit through surcharge practice.

Originality/value

The authors’ investigation extends the literature on consumers’ price processing by identifying the important moderators (seller reputation, product category, and elaboration) and probing into the decision process (via the response time). The results suggest prescriptive strategies for online sellers.

Abstract

This chapter focuses on pedagogies of working with diversity centers on West-East reciprocal learning through a Reciprocal Learning Program in preservice teacher education between a Canadian university and a Chinese university. By presenting our initial analysis of fieldwork with our Teacher Education Reciprocal Learning Program participants through excerpts from newsletters, surveys, and interviews, we explore how participants from both China and Canada made sense of their learning from the other cultural and educational system through the Reciprocal Learning Program within broad educational, social, and cultural contexts. We argue that both global and multicultural dimensions are cultivated in reciprocal learning that infused the lived experiences of both Canadian and Chinese preservice teacher candidates. We discuss the pedagogic implications for working with diversity and believe that reciprocal learning can take place while working with people from different cultures with an attitude of mutual respect and appreciation and an appetite for learning in our increasingly interconnected world.

Abstract

There are some notable ethical problems about role obligations, including the three prominent issues of role relativism, role definition, and role identification. The first is the problem to what extent roles may create duties or rights at odds with other moral requirements, the second is where roles are unclear or conflicting in what they prescribe, and the third is about the extent to which people commit themselves to their roles, or dissociate themselves from those roles. The three problems are significant in business ethics. A Confucian approach to roles can assist in dealing with them. Classical texts suggest a nuanced approach to roles, which allows greater flexibility, paying attention to context and detailed circumstances, always relating role prescriptions to respect and concern for other people, and emphasizing the importance of sincerity and authenticity in role performance. Such an account is consistent with virtue ethics approaches to business ethics.

Abstract

The human family lays the foundation for altruism. All babies be they human or animal are born helpless. Their very survival depends on the love and affection that are already embedded in the hearts of mothers (Choudhury, 1995, vol. 2). No amount of selfish attitude of mothers, not at least from short life span, can help in the growth of their off‐springs. One can argue that it is the self‐interested motive of the parents and most particularly the mothers of getting supports in their old days that drives them to be altruistic rather than selfish. Being altruistic means undertaking a lot of sacrifice in terms of personal pleasure and happiness merely for seeing pleasure and happiness in others regardless of any human bondage. An egoistic person, on the other, would never care for others. Personal level satisfaction only dominates the mind of an extremely egoistic or self‐centered man.

Abstract

The basis of human creation lays the foundation for altruism. Babies, be they human or animal are born helpless. Their very survival depends on the love and affection that are already embedded in the hearts of mothers. No amount of selfish attitude of mothers, not at least from short life span, can help in the growth of their off‐springs. One can argue that it is the self‐interested motive of the parents and most particularly the mothers of getting supports in their old days that drives them to be altruistic rather than selfish. Being altruistic means undertaking a lot of sacrifice in terms of personal pleasure and happiness merely for seeing pleasure and happiness in others regardless of any human bondage. An egoistic person, on the other hand, would never care for others. Personal level satisfaction only dominates the mind of an extremely egoistic or self‐centered man.

Abstract

Purpose

This paper aims to empirically analyze the role of FDI technology spillover effects in the development patterns of ASEAN.

Design/methodology/approach

The paper is based on the analytical framework of Borensztein by utilizing time‐series data between 1990 and 2008 in ASEAN countries. Models (1)‐(3) estimate parameters by adopting OLS, and Model (4) uses dummy saturation methods in PC Give, Oxmetrics 6 to determine significant dummy variables automatically. By judging the overall significance of each variable and the model, Model (4) has a substantial improvement, and is finally selected to judge the education threshold of each country.

Findings

The empirical results render support to the existence of technology spillovers in ASEAN. The regression results also suggest that it is necessary to combine FDI technology spillovers with domestic human capital, that is, in the process of promoting economic development. China's FDI in ASEAN requires lower education threshold, and also has positive effect on economy growth in six countries of ASEAN.

Research limitations/implications

As this paper investigates data from many countries, there are some unavoidable differences in the statistical sources and the calibre of data. It is inevitable to have some inaccuracies. This paper tries to process the data into similar calibres and units.

Practical implications

The paper examined whether total FDI, intra‐ASEAN FDI and FDI from China have played exactly the same role in ASEAN countries. Accordingly, the paper put forward suggestions after combining the characteristics of FDI from China with different local situations of ASEAN host countries.

Originality/value

The paper, respectively, takes data of total FDI, intra‐ASEAN FDI, FDI from China into the FDI variable in the model, and get three sets of results for each country. The year dummy variable is newly added to the original framework of Borensztein in order to test whether the dependent variable can be affected to a large extent by potential great changes in macro‐economies.

Abstract

Purpose

The purpose of this paper is to develop an effective cost borrowing model of qualitative factors that are relevant to micro and small enterprises (SMEs) better performance.

Design/methodology/approach

A valid research instrument was utilized to conduct a survey on 359 SMEs (131 retail businesses, 125 service businesses, 48 farming businesses and 55 other businesses) and 897 respondents that are representative of 397 SMEs and 1,087 respondents. Correlation and regression analysis were conducted to ascertain the validity of the hypotheses.

Findings

It was established that cost of borrowing elements (interest rate and loan processing costs) are associated with SME performance. Furthermore, cost of borrowing as a whole accounts for 31.1 percent of the variation in performance Uganda’s SMEs.

Research limitations/implications

Only a single research methodological approach was employed, future research through interviews could be undertaken to triangulate. Multiple respondents in SMEs (owner, manager and cashier) were studied neglecting others. Furthermore, the study used the cross-sectional approach – a longitudinal approach should be employed to study the trend over years. Finally, cost of borrowing was studied and by the virtual of the results, there are other factors that contribute to SME performance that were not part of this study.

Practical implications

There is need to intensify initiatives to encourage greater understanding and acceptance of cost of borrowing, select appropriate elements that includes interest rate and loan processing costs in order to have affordable source of financing to establish and grow SMEs, provide employment, competitive and contribute to countries GDP.

Originality/value

This is the first paper in Sub-Saharan Africa to test empirically the relationship between cost of borrowing and performance of SMEs in the Ugandan context.
