Abstract

The production of biohydrogen from rice mill wastes, including rice bran and rice mill effluent by Clostridium acetobutylicum NCIM 2877 was investigated in a batch culture system and optimized the temperature and pH conditions. At 35 °C with initial pH of 5.2 a yield of 55.7±0.8 ml with 88.6 ± 0.3% substrate utilization and at pH 6 the production was 68.7 ± 0.9 ml with 85 ± 1.0 % substrate utilization. Addition of metal ions resulted in better yield and substrate utilization efficiency of the bacteria. FeSO4.7H2O at a concentration of 50 mg/l gave 79.7 ± 1.5 ml with 96% of substrate utilization. Cobalt effected the production greatly by giving 96.3 ± 0.9 ml with 95.3 ± 0.7% of substrate utilization whereas Nickel didn’t showed much effective results by giving only a maximum of 74.7 ± 1.5 ml production at 25 mg/l concentration. Conclusively, it can be stated that rice mill wastes can be used as a substrate and use of metal ions will play a key role in the enhancement of biohydrogen production.

Abstract

Purpose

The aim of this study is to understand the effects of psychological social and financial perceptions of post-retirement life and demographic characteristics on retirement planning behaviour (RPB) of the employees from different occupational sectors.

Design/methodology/approach

The primary data from 400 employees in central government, state government and private sector is collected through a structured questionnaire. The questionnaire comprised of 43 items to measure social and financial perceptions and RPB along with demographic information. An exploratory factor analysis (EFA) and multiple linear regression (MLR) analysis are performed to find the significant variables of social and financial perceptions influencing the RPB.

Findings

The results of exploratory factor analysis revealed three principle components of social perceptions, four of financial perceptions and three of RPB. The role clarity, involvement, obligations, uncertainty and preparations have significant impact on RPB. This study found a moderate positive correlation between RPB and extracted factors of social and financial perceptions. The study confirms the significant effect of demographic variables such as age, marital status, occupational sector, income and education levels on RPB.

Originality/value

The study has number of implications for government and private sector organisations involved in offering the retirement planning solutions as well as to the employees. The stakeholders may take a note of the role of psychological social (role clarity and social involvement) and financial (financial obligations, uncertainty and preparation for post-retirement life) perceptions that influence RPB. The study also provides an insight to the policy makers for considering the demographic information such as age, education, marital status and income of the employees while designing/offering the choices of retirement plans to them. Further studies are recommended to validate the findings of this study in terms of testing the effect of psychological social and financial perceptions on retirement planning behaviour of the employees.

Abstract

Purpose

The purpose of this paper is to identify the dimensions of predisposition towards foreign brands (PTFB) for Indian consumers and examine their impact on materialism/materialist value (MAT). The study further conducts an in-depth analysis of these constructs for possible variations across consumer demographics.

Design/methodology/approach

Using a structured questionnaire, primary data were collected from 487 respondents in the city of Delhi and National Capital Region (NCR). While a modified scale was developed to operationalize PTFB, the measurement instrument for MAT was adapted on the basis of an extensive literature review. Statistical techniques such as Exploratory factor analysis, Confirmatory factor analysis, t-test, analysis of variance (ANOVA) and regression analysis were used to test various hypotheses of the study.

Findings

The study identified five dimensions of PTFB, namely, “Reputation”, “Preference”, “Country of Origin”, “Accessibility” and “Quality”, through confirmatory factor analysis in structural equation modelling. Except for “Preference” and “Accessibility”, all remaining dimensions were found to be exerting a significant impact on MAT. The results further indicate that consumers’ PTFB as well as their MAT differs across demographics such as age, income, gender, occupation and qualification.

Practical implications

The paper brings to the fore useful insights for marketers of foreign brands. The findings can be effectively used for developing a more focused marketing strategy for Indian consumers by helping in identifying demographic segments that are more responsive and susceptible to the entry of foreign brands in Indian markets.

Originality/value

The paper attempts to develop a more robust instrument for measurement of consumers’ PTFB and provides dimensions constituting the construct for consumers of emerging markets such as India. The current research also indicates that there exists a significant variation in PTFB and MAT for different demographic segments of consumers.
