Caste and Distributive Justice: Can Social Policy Address Durable Inequalities?

This article examines the impact of social policy interventions on caste inequalities. The article accepts the proposition by Charles Tilly that durable inequalities are entrenched solutions while addressing organizational problems of society. The political economy approach to caste enables us to understand how the discriminatory practices around caste are durable. The article examines two types of social policies set up to deal with caste discrimination. The first type of policies are particularistic policies which directly address the concerns of the members of the depressed castes. The second type of policies are aimed at the general population, but from which a large number of depressed caste members benefit. The article concludes that both types of policies have only an ameliorative function rather than an emancipation role. It is argued here that ‘social policy’ in the context of durable inequality requires redefinition to include political interventions. The administrative view of social policy focuses heavily on the state, and in the context of durable inequality, the legitimacy of the state itself is in question. On the other hand, mobilization around politics addresses the organizational anomaly of the society, which is at the root of durable inequality.     

A Lean Six Sigma framework for the reduction of ship loading commercial time in the iron ore pelletising industry

Evidence suggests that specifically designed frameworks to implement Lean Six Sigma (LSS) projects to tackle particular problems are more effective than ‘generic’ versions. This paper proposes an implementation framework to effectively deploy LSS to improve a key operation and performance indicator, i.e. ship loading commercial time, of one of the largest world producer of iron ore. This article therefore contributes with a refined framework to effectively implement LSS, and documents its successful application and effectiveness within the context of the case organisation. The LSS framework and project contributed in helping the studied organisation to improve both the capability of its ship loading process and commercial time by more than 30%, resulting in operational savings in the range of $300,000 USD per year. The systematic nature of the framework proposed also helped the organisation to establish a standardised routine to improve its operations. Managerial implications exposing the challenges faced during the implementation of LSS are also discussed to serve as lessons learnt to be considered in other LSS projects. Managers and engineers incharge of improving operations and processes can benefit from this paper as it can be used as a guide to direct the conduction of LSS projects and the empirical application of its principles and tools.     

Lean and green in the transport and logistics sector – a case study of simultaneous deployment

The transport and logistics sector is of vital importance for the stimulation of trade and hence the economic development of nations. However, over the last few years, this sector has taken central stage in the green agenda due to the negative environmental effects derived from its operations. Several disciplines including operations research and sub-areas of supply chain management such as green supply chains, green logistics and reverse logistics have tried to address this problem. However, despite the work undertaken through these disciplines, theoretical or empirical research into the sequential or simultaneous deployment of the lean and green paradigms, particularly, in the road transport and logistics sector is limited. This paper presents a case study where both paradigms have been combined to improve the transport operations of a world leader logistics organisation in the metropolitan area of Monterrey, Mexico. To do this, a systematic methodology and a novel tool called Sustainable Transportation Value Stream Map (STVSM) were proposed. The results obtained from the case study indicate that the concurrent deployment of the green and lean paradigms through such methodology and the STVSM tool is an effective approach to improve both operational efficiency and environmental performance of road transport operations. The paper can be used as a guiding reference for transport and logistics organisations to undertake improvement projects similar to the one presented in this paper. Additionally, this research also intends to stimulate scholarly research into the application of lean and green paradigms in the transport and logistics sector to expand the limited research pursued in this area.     

Changes in productivity of Spanish university libraries

This paper analyzes productivity growth, technical progress, and efficiency change in a sample of 34 Spanish university libraries between 2003 and 2007. Data envelopment analysis and a Malmquist index are combined with a bootstrap method to provide statistical inference estimators of individual productivity, technical progress, pure efficiency, and scale efficiency scores. To calculate productivity, a three-stage service model has been developed, examining productivity changes in the relationships between the libraries' basic inputs, intermediate outputs, and final outputs. The results indicate a growth in the productivity of the libraries (relationship between basic inputs and intermediate outputs) and in the productivity of the service (relationship between basic inputs and final outputs). The growth in productivity in both relationships is due to technical progress. If the variable representing the use of electronic information resources is removed from the final output, the result is a significant reduction in productivity.     

The shared leadership of teams: A meta-analysis of proximal,distal, and moderating relationships

The current meta-analysis examines the relationship between shared leadership and team performance. It also assesses the role of team confidence (i.e., collective efficacy and team potency) in this relationship. Mediation analyses supported the hypothesis that team confidence partially mediates the effects of shared leadership on team performance. We also found support for the notion that shared leadership explains unique variance in team performance, over and above that of vertical leadership. Furthermore, a variety of substantive continuous and categorical variables were investigated as moderators of the shared leadership–team performance relationship. Specifically, the relationship between shared leadership and team performance was moderated by task interdependence, team tenure, and whether performance was objectively versus subjectively measured. Finally, results suggest that the approach used when measuring shared leadership can also play a role in the observed validity. Theoretical and practical implications of these findings are discussed.     

Is Agency Skin Deep? Surface Attributes Influence Infants' Sensitivity to Goal‐Directed Action

Three studies investigated the role of surface attributes in infants' identification of agents, using a habituation paradigm designed to tap infants' interpretation of grasping as goal directed (Woodward, 1998). When they viewed a bare human hand grasping objects, 7‐ and 12‐month‐old infants focused on the relation between the hand and its goal. When the surface properties of the hand were obscured by a glove, however, neither 7‐ nor 12‐month‐old infants represented its actions as goal directed (Study 1). Next, infants were shown that the gloved hands were part of a person either prior to (Study 2) or during (Study 3) the habituation procedure. Infants who actively monitored the gloved person in Study 2 and older infants in Study 3 interpreted the gloved reaches as goal directed. Thus, varying the extent to which an entity is identifiable as a person impacts infants' interpretation of the entity as an agent.     

Race/Ethnicity and Stop‐and‐Frisk: Past,Present, Future

Scholarly debates surrounding stop‐and‐frisk typically assess the effectiveness and lawfulness of stop‐and‐frisk. Notwithstanding these efforts, recent reviews have excluded some recent research that addresses its impact on racial and ethnic immigrants. Understanding how the practice of stop‐and‐frisk affects racial and ethnic immigrants is worth including in reviews of these policies, considering the recent growth of research involving crime and immigrants that largely finds that immigration does not result in higher levels of crime. This review includes recent work showing that overall enforcement – stops and arrests – is higher in immigrant communities despite their lower levels of criminal involvement and recent work exploring differences among first‐generation and second‐generation immigrants in perceptions of police stops. Finally, some suggestions for the future of stop‐and‐frisk research are considered.     

Parents’ education as a determinant of educational childcare time

We analyze the relationship between parents’ education and the time devoted to childcare activities, with a focus on activities aimed at increasing the child’s human capital. We use the sample of opposite-sex couples with children under age 18, from Spain (2002) and the UK (2000), included in the Multinational Time Use Study. By estimating a seemingly unrelated regressions tobit model, we find that mothers’ education is associated with an increase in the time devoted to educational childcare by fathers in both Spain and the UK, while it is associated with an increase in the time devoted to educational childcare by mothers in Spain. We also find that fathers’ education has no effect on the time devoted to educational childcare time by either parent. It seems that what really matters in determining the time devoted to educational childcare at the couple level is the educational level of the mother.     

The International Multidimensional Fertility Index: The European Case

We propose an index to measure the degree of ability or desire of the population in a given country to have children, via an analysis of certain factors that may have a positive or negative influence on the fertility rate of that country. Using data for the twenty-eight countries of the European Union, and Principal Components Analysis, we construct the International Multidimensional Fertility Index as a combination of four dimensions: (1) Economy and family, (2) Attitudes and habits, (3) Work–Life Balance, and (4) Policy, along with nineteen distinct variables. We find that Denmark, the Netherlands, and Luxembourg are among the countries with the highest value of the index, and they also have high fertility rates within the EU. At the other end of the spectrum, Latvia, Cyprus, and Greece, are ranked in the last positions according to our index, countries that also present low values in their fertility rates. We also find a positive correlation between the value of our index and country fertility rates, an indication that our index may be capturing country differences in the conditions for bearing children, with higher values of the index indicating better conditions for childbirth and childrearing. To the extent that international data becomes available, our methodology will allow for the construction of international rankings, helpful in identifying cross-country differences in the conditions for fertility.
