Abstract

Purpose

The purpose of this paper is to study the perceived relationship between corporate social responsibility (CSR) and corporate effectiveness (CE) amongst undergraduate and post-graduate students in India and Mauritius. The paper explores the differences in perception of CSR and CE w.r.t profitability, long-term success and short-term success between the different student groups.

Design/methodology/approach

This paper explores past studies done by researchers and practitioners and uses a survey method for data collection amongst students in India and Mauritius.

Findings

Set in the context of current ethical and business challenges facing business leaders, the paper provides insights and recommendations on the perceived relationship between CSR and CE. Recommendations have been provided for leveraging the perception of CSR amongst students as they aspire to become future business leaders.

Research limitations/implications

Researchers and practitioners are encouraged to explore and test the proposals further in different contexts and countries.

Practical implications

The paper suggests that the research reinforces the relationship between CSR and CE in the context of business and current student perception globally.

Social implications

Management students are future managers and the study of their perception towards social responsibility has a lot of bearing on their future decision making with respect to these issues.

Originality/value

This paper highlights the different student views on CSR and CE in India and Mauritius and will encourage future researchers and organizations to further expand on this perception.

Abstract

Purpose

Degradation measurement of some products requires destructive inspection; that is, the degradation of each unit can be observed only once. For example, observation on the mechanical strength of interconnection bonds or on the dielectric strength of insulators requires destruction of the unit. Testing high-reliability items under normal operating conditions yields a small amount of degradation in a reasonable length of time. To overcome this problem, the items are tested at higher than normal stress level – an approach called an accelerated destructive degradation test (ADDT). The present paper deals with formulation of constant-stress ADDT (CSADDT) plan with the test specimens subject to stress induced by temperature and voltage.

Design/methodology/approach

The stress–life relationship between temperature and voltage is described using Zhurkov–Arrhenius model. The fractional factorial experiment has been used to determine optimal number of stress combinations. The product's degradation path follows Wiener process. The model parameters are estimated using method of maximum likelihood. The optimum plan consists in finding out optimum allocations at each inspection time corresponding to each stress combination by using variance optimality criterion.

Findings

The method developed has been explained using a numerical example wherein point estimates and confidence intervals for the model parameters have been obtained and likelihood ratio test has been used to test for the presence of interaction effect. It has been found that both the temperature and the interaction between temperature and voltage influence the quantile lifetime of the product. Sensitivity analysis is also carried out.

Originality/value

Most of the work in the literature on the design of ADDT plans focusses on only a single stress factor. An interaction exists among two or more stress factors if the effect of one factor on a response depends on the levels of other factors. In this paper, an optimal CSADDT plan is studied with one main effect and one interaction effect. The method developed can help engineers study the effect of elevated temperature and its interaction with another stress factor, say, voltage on quantile lifetime of a high-reliability unit likely to last for several years.

Abstract

This article documents instances of racism that have previously acted as barriers to Indian students' academic success in Australia. It is felt that such incidents would not have happened to students from, for example, China or Japan, as their governments would have taken more serious steps against the Australian government. There is a feeling in India that the Indian government can be seen as weak. Against this background, the article looks at potential reasons for racially motivated attacks against Indians in Australia, and at what can be done to reduce these, as well as both the Australian and Indian government responses to the particular instances reported.

Abstract

Purpose

Zero-failure reliability testing aims at demonstrating whether the product has achieved the desired reliability target with zero failure and high confidence level at a given time. Incorporating accelerated degradation testing in zero-failure reliability demonstration test (RDT) facilitates early failure in high reliability items developed within short period of time to be able to survive in fiercely competitive market. The paper aims to discuss these issues.

Design/methodology/approach

The triangular cyclic stress uses one test chamber thus saving experimental cost. The parameters in model are estimated using maximum likelihood methods. The optimum plan consists in finding out optimum number of cycles, optimum specimens, optimum stress change point(s) and optimum stress rates.

Findings

The optimum plan consists in finding out optimum number of cycles, optimum specimens, optimum stress change point(s) and optimum stress rates by minimizing asymptotic variance of estimate of quantile of the lifetime distribution at use condition subject to the constraint that total testing or experimental cost does not exceed a pre-specified budget. Confidence intervals of the design parameters have been obtained and sensitivity analysis carried out. The results of sensitivity analysis show that the plan is robust to small deviations from the true values of baseline parameters.

Originality/value

For some highly reliable products, even accelerated life testing yields little failure data of units in a feasible amount of time. In such cases accelerated degradation testing is carried out, wherein the failure termed as soft failure is defined in terms of performance characteristic of the product exceeding its critical (threshold) value.
