Barriers in Green Lean implementation: a combined systematic literature review and interpretive structural modelling approach

Green Lean has recently emerged as an alternative strategy for organisations to pursue both operational and sustainability excellence. The interest on this approach has rapidly risen in both academic and industry circles. However, despite this interest, very limited research has focused on its implementation, and no research has investigated the barriers that hinder the success of such activity. This study investigates the Green Lean implementation barriers and their contextual relationships and effects on the integration and deployment of this approach. A Systematic Literature Review (SLR), Interpretative Structural Modelling and fuzzy Matriced’ Impacts Croise’s Multiplication Appliqée a UN Classement (MICMAC) analyses were carried out. Fifteen barriers were extracted from the SLR and then validated in consultation with industry and academic experts. The Interpretive Structural Modelling (ISM) method was used to understand the relationship between the fifteen barriers and to develop a hierarchical model of these. The different barriers were classified into ‘linkage’ and ‘dependent’ barriers by using MICMAC analysis. The results suggested that all the identified barriers play an important role, and hence can equally act as a significant hurdle to the implementation of Green Lean projects. This study can help managers and policy-makers in better understanding these barriers. Thus, they can be assisted in managing and prioritising barriers towards the successful implementation of Green Lean initiatives for better financial and environmental performance.     

The Dynamics of Multidimensional Poverty in Contemporary Australia

Progressively more researchers argue that successfully measuring social inequalities requires moving from income-based to multidimensional poverty indicators, but evidence on Australia is still largely reliant on the former. Using long-running panel data from the Household, Income and Labour Dynamics in Australia Survey we examine trends in multidimensional poverty in Australia between 2001 and 2013. We find that this has been relatively stable, with some evidence of an upwards trend following from the 2008 Global Financial Crisis. However, a closer examination of the individual components reveals a more dynamic picture. Deprivation concerning health, material resources, social support and education increased over the 13-year observation period, offsetting decreases in deprivation concerning safety perceptions, employment and community participation. Additionally, using counterfactual simulations, we examine the relative roles of different poverty domains in explaining changes in Australian multidimensional poverty. We find that recent year-on-year changes in multidimensional poverty are mainly driven by fluctuations in social support, health and material resources. Altogether, our findings suggest that Australian poverty-reduction policies would enhance their effectiveness and efficiency by focusing on improving disadvantage in the domains of health and material resources.     

A semi-parametric estimation of a survival function from incomplete and doubly censored data

The purpose of this paper is to present a semi-parametric estimation of a survival function when analyzing incomplete and doubly censored data. Under the assumption that the chance of censoring is not related to the individual's survivorship, we propose a consistent estimation of survival. The derived estimator treats the uncensored observations nonparametrically and uses parametric models for both right and left censored data. Some asymptotic properties and simulation studies are also presented in order to analyze the behavior of the proposed estimator.
