Abstract
Applied econometric analysis is often performed using data collected from large-scale surveys. These surveys use complex sampling plans in order to reduce costs and increase the estimation efficiency for subgroups of the population. These sampling plans result in unequal inclusion probabilities across units in the population. The purpose of this paper is to derive the asymptotic properties of a design-based nonparametric regression estimator under a combined inference framework. The nonparametric regression estimator considered is the local constant estimator. This work contributes to the literature in two ways. First, it derives the asymptotic properties for the multivariate mixed-data case, including the asymptotic normality of the estimator. Second, I use least squares cross-validation for selecting the bandwidths for both continuous and discrete variables. I run Monte Carlo simulations designed to assess the finite-sample performance of the design-based local constant estimator versus the traditional local constant estimator for three sampling methods, namely, simple random sampling, exogenous stratification and endogenous stratification. Simulation results show that the estimator is consistent and that efficiency gains can be achieved by weighting observations by the inverse of their inclusion probabilities if the sampling is endogenous.

Abstract
Uses a unified expression, called Hh,vφ1φ2 entropy to study the asymptotic properties of entropy estimates. Shows that the asymptotic distribution of entropy estimates, in a stratified random sampling set‐up, is normal. Based on the asymptotic precision of entropy estimates, optimum sample size allocations are developed under various constraints. Gives the relative precision of stratified and simple random sampling. Also provides applications to test statistical hypotheses and to build confidence intervals.

Abstract
Purpose
The purpose of this paper is to develop a new model, namely service quality measurement in higher education in India (SQM‐HEI) for the measurement of service quality in higher educational institutions.
Design/methodology/approach
Data were collected by means of a structured questionnaire comprising six sections. Section A consists of ten questions pertaining to teaching methodology (TM). Sections B consists of five questions pertaining to environmental change in study factor (ECSF). Section C consists of eight questions relating to disciplinary measures taken by the institutions. Section D consists of five questions related to the placement‐related activities and in part E two questions provide an overall rating of the service quality, satisfaction level. Finally, in part F 13 questions pertaining to student respondent's demographic profile information were given. All the items in Sections A‐E were presented as statements on the questionnaire, with the same rating scale used throughout, and measured on a seven‐point, Likert‐type. In addition to the main scale addressing individual items, respondents were asked in Section E to provide an overall rating of the service quality, satisfaction level. For conducting an empirical study, data were collected from final‐year students of higher educational institutions across Tamil Nadu. The sampling procedure used for the study was stratified random sampling. The stratification has been done based on the region Chennai, Coimbatore, Madurai, Tiruchirappalli, and nature of institution, government university, government college, aided college, private university and self‐financing college. While selecting the institutions from each category, non‐probabilistic convenience and judgmental sampling technique were used. However, within such institutions, the respondents were selected by stratified random sampling.
Findings
The SQM‐HEI‐mediated model argued that the placement is the better interactions of the quality of education in India. The model reveals that the quality of education is based on the best faculty (TM), the excellent physical resources (ECSF), a wide range of disciplines (DA) which paved the diverse student body and to improve the employability of the graduates (placement as mediating factor) coming out of the higher educational institutions in India. The above model proves that the placement is the mediated factor for various dimensions of quality education. SQM‐HEI model would help in identify three service areas to be focused in the higher educational institutions for improving the quality of . These three dimensions of quality correlated between the sub‐dimension variables and it is very necessary for improving the quality of higher education in India. The educationist says that, education is a change of behavior of students. Hence, the higher educational institutions should come forward to adapt the sub‐dimensions of quality variables to enhance the outcome of education.
Originality/value
The model described in this paper will assist academic institutions when mapping the level of service quality and thereby enhance the same.

Abstract
Although it is well recognised that the collapse of the Soviet Union and the subsequent widespread social and economic changes impacted on the levels and distribution of physical health, there is very limited evidence on the social patterning of mental health in the countries that emerged. The aim of this paper is to assess levels of psychological distress and describe its demographic, social and economic correlates in eight former Soviet countries.Cross‐sectional surveys using multi‐stage random sampling were conducted in Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine. A standardised questionnaire was used for all countries, including the main outcome for this study of psychological distress, which consisted of 12 items on symptoms of psychological distress. Respondents who repor ted 10‐12 of the symptoms were considered to have a high psychological distress score. Multivariate logistic regression analysis was then used to investigate how demographic, social and economic factors were associated with a high psychological distress score.High psychological distress in seven of the eight countries ranges from 3.8% in Kazakhstan to 10% in Ukraine but was substantially higher (21.7%) in Armenia. Factors associated with psychological distress in the multivariate analysis included: being female; increasing age; incomplete secondary education; being disabled; experiencing two or more stressful events in the past year; lack of trust in people; lack of personal suppor t in crisis; being unemployed; and poor household economic situation.The study contributes evidence on the association of impoverishment and social isolation on psychological distress in countries of the former Soviet Union and highlights the impor tance of exploring ways of improving mental health by addressing its social determinants.

Abstract
Purpose
One area of concern for Islamic economics is the challenges and discrimination experienced in Muslim societies and the lower human development indices compared to the Western counterparts. It is possible that the application of the theory of Maqāsid al Sharī’ah (TMS) could provide some insight on the problems and probably offer some support to the policymaker on the direction to take. The purpose of this paper is to apply TMS to validate the factors of human development.
Design/methodology/approach
The primary data were collected using a questionnaire. The target respondents were Muslims from Nigeria. Both stratified and purposeful random sampling techniques were used to collect the data, and the analyses were done by SPSS and AMOS statistical software.
Findings
In validating factors that contribute to human development, TMS framework is used, and the model integrates five factors which are considered most likely to have influence on human development. The model proposes that individual factors such social justice and human rights have effects on the factors of human development.
Originality value
This study provides understanding on the contributing factors to the persistent challenges of human development in predominantly Muslim settings. Previous research which has applied TMS focused more on its financial relevance and has not attempted to understand the situation and proffer solution.

Abstract
Purpose
The purpose of this paper is to develop a thorough understanding of the adoption of logistics and supply chain management (SCM) in practice, particularly at a strategic level, through an investigation of the four perspectives taxonomy of the relationship between logistics and SCM.
Design/methodology/approach
Based on a comprehensive literature review, three specific research questions are proposed. The empirical work addresses these questions and comprised three phases: focussed interviews, a questionnaire survey and focus groups.
Findings
The findings provide a usage profile of the four perspectives and indicate a divergence between the understanding and adoption of logistics and SCM principles and concepts at a strategic level in firms. The findings also identify the critical success factors (CSFs) and inhibitors to success in addressing this divergence.
Research limitations/implications
The insights generated using the authors’ methodologically pluralist research design could be built upon to include case studies, grounded theory and action research. Replicating the research in other geographical areas could facilitate international comparisons.
Practical implications
The findings allow practitioners to compare their perspectives on the relationship between logistics and SCM with those of their peers. The CSFs and inhibitors to success provide a rational basis for realising the strategic potential of logistics and SCM in practice.
Originality/value
New insights are generated into practitioner perspectives vis-à-vis logistics vs SCM. A fresh understanding of those factors which drive and hinder the adoption of strategic SCM is also developed and presented.

Abstract
Purpose
There has been an exponential proliferation of higher engineering educational institutions in India. The purpose of this paper is to seek to investigate students' perceptions of the level of Commitment of Top Management and Leadership (CTML) and Education Service Design and Delivery (ESDD) in Government Run Engineering Colleges (GREC), Privately Funded Engineering Colleges (PFEC) and Privately Funded Deemed Universities (PFDU) in India. The paper also strives to find out the significant predictors of Overall Engineering Education Excellence (OEEE).
Design/methodology/approach
A conceptual model has been developed linking Total Quality Management (TQM) elements and OEEE. The data were obtained from a survey of 992 students of higher engineering institutions in South India and analyzed using SPSS.
Findings
Significant differences among GREC, PFEC and PFDU were noticed in several TQM dimensions under study, and also in OEEE. The findings show correlation between the seven TQM variables and OEEE. CTML made a significant contribution toward attaining OEEE. Campus Facilities and Congenial Learning Environment also contributed greatly to OEEE.
Research limitations/implications
The sample is limited to engineering institutions in a particular geographical area of India. Related study with a global perspective can be taken up in the future.
Practical implications
The comparative analysis of higher engineering institutions as well as the results of the investigative study of the impact of TQM on overall engineering educational excellence will prove useful to academic leadership.
Originality/value
The research framework presented in this paper is valuable to the top managements of higher engineering institutions.

Abstract
Purpose
The purpose of this paper is to compare levels of psychological distress in 2001 and 2010 in eight countries of the former Soviet Union and to explore how these changes vary for different population groups.
Design/methodology/approach
Data were collected using two related studies from 2001 (n=14,242) and 2010 (n=15,081). Both studies consisted of nationally representative cross‐sectional household surveys in Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine using a standardized questionnaire. Psychological distress was measured using a 12 item instrument, with scores of 10‐12 indicating high psychological distress. Changes in prevalence of high psychological distress were measured between 2001 and 2010 by country, gender, age group, educational level, disability status, personal support and household economic status using descriptive and prevalence rate ratio analysis.
Findings
Levels of high psychological distress decreased from 8.7 per cent in 2001 to 4.9 per cent in 2010 for the whole study region (4.5 per cent to 2.8 per cent for men; 12.0 per cent to 6.5 per cent for women). All study countries recorded decreases in high psychological distress. The adjusted relative rate ratios indicate the observed decreases have not been experienced by men, older age groups, less educated respondents, those with a disabling health condition, low levels of support and bad household economic status.
Originality/value
The study shows decreases in levels of high psychological distress in the study countries, but that decreases were less for socially and economically marginalised populations. This highlights the cycle of poverty, social exclusion and poor mental health in the region. Despite decreases of psychological distress among women, they continue to bear a significantly higher burden than men.

Abstract
Purpose
As part of the European continuing vocational training survey, this paper aims to give an overview of the evolutions in continuing vocational training (CVT) in Belgian companies, by comparing both the results of the survey of 1994 and those of 2000/2001.
Design/methodology/approach
In Belgium 1,129 companies took part in the survey of 2000/2001. The sample was representative of Belgian companies with more than ten employees, making use of two criteria: company size and economic activity. The data were collected by telephone, post and face‐to‐face interviews based on a standardised questionnaire.
Findings
The findings suggest that the Belgian companies increasingly invested in both formal and informal learning. The results concerning “access to CVT courses” and “efforts in financial terms” also show a positive evolution. Finally, the study reveals that the CVT‐policy within companies has become more formal. Despite this positive tendency in general, not all employees seem to have the same opportunities to take part in CVT. The company size and, to a lesser extent, the activity of the company are two important determinants for the investment in CVT.
Research limitations/implications
The study focused on the formal types of CVT; consequently, it gives only a partial outline of the training efforts in Belgian enterprises. Future research should also include the other forms of CVT. Furthermore, the data are taken from enterprises; as such, they do not enable us to take into account the individual heterogeneity.
Practical implications
A two‐track policy is required to stimulate both training and non‐training enterprises to invest in their human resources. More specifically, the opportunities of on‐the‐job training and external CVT courses should be enhanced and it is recommended to examine which role the different providers can play.
Originality/value
The CVT survey is a useful source of statistical information for monitoring continuing vocational training by both policy‐makers and enterprises.
