Critical success factors of medical technology supply chains

This paper investigates Critical Success Factors that affect the performance of organizations involved in Medical Technology supply chains (MTSCs) in Germany. The Medical Technology sector in Germany is considered an innovative, fast-growing and promising industry, being third behind the USA and China as the biggest market in the world, worth 29.9 billion euros in 2017. MTSCs in this country are under pressure from health service funding and cheaper imports, primarily from China. Consequently, supply chain success is of high importance and OEM operational improvements are critical. This exploratory study involved a multiple case study approach where 15 OEMs within German MTSCs were investigated. Following within-case and cross-case analysis, empirical results led to the development of testable propositions, which constitute a foundation for further research investigation. The findings show that there are six, prioritized Critical Success Factors for MTSCs that include sales and operations planning, product development process and quality and compliance. These findings challenge existing assumptions about Critical Success Factors within MTSCs, providing practitioners with strategies showing that re-prioritized CSFs should improve the operational performance of OEMs.     

An exact approach for the balanced <Emphasis Type="Italic">k</Emphasis>-way partitioning problem with weight constraints and its application to sports team realignment

In this work a balanced k-way partitioning problem with weight constraints is defined to model the sports team realignment. Sports teams must be partitioned into a fixed number of groups according to some regulations, where the total distance of the road trips that all teams must travel to play a double round robin tournament in each group is minimized. Two integer programming formulations for this problem are introduced, and the validity of three families of inequalities associated to the polytope of these formulations is proved. The performance of a tabu search procedure and a branch and cut algorithm, which uses the valid inequalities as cuts, is evaluated over simulated and real-world instances. In particular, an optimal solution for the realignment of the Ecuadorian football league is reported and the methodology can be suitable adapted for the realignment of other sports leagues.     

Overeducation of Young Workers in Spain: How Much Does the First Job Matter? Social Indicators Research

This article contributes to recent overeducation literature on the impact of an initial education mismatch on workers’ future careers. Specifically, using the 2009 ad-hoc module of the Spanish Labour Force Survey, we quantify the differences in the probability of overeducation depending on the quality of individuals’ first match. To do this, we apply an extension of the recursive bivariate probit model, which allows potential endogeneity problems to be taken into account, as well as a dissimilar impact of the initial match for workers with different educational attainment. The results indicate that overeducation is a trap, since young workers who were mismatched in their first job are 40.2 percentage points more likely to be overeducated in a later one than those who were not. When decomposing this difference in two parts, one related to the pure effect of the initial mismatch and another one related to workers’ characteristics, we conclude that the pure effect is more important, and it depends on educational attainment.     

Spatial Analysis of the Relationship Between a Life Quality Index,HDI and Poverty in the Province of Buenos Aires and the Autonomous City of Buenos Aires,Argentina

The study of Quality of Life, Poverty and Human Development shares several elements. Nonetheless, while poverty is a measure of “lack” based on a set of basic need variables (unsatisfied basic needs—UBN), human development index (HDI) is derived from the notion of human capabilities. Quality of Life, however, is a measure of achievement. Our goal is to analyze the degree of spatial correspondence between a life quality index (LQI) and the other indices by using bivariate spatial autocorrelation with its global and local values. The comparison of these three indicators at a municipal level in the province of Buenos Aires and in the Autonomous City of Buenos Aires (the Federal Capital of Argentina) reveals a medium spatial correspondence which leaves room for discussion about the scope and limitations of the indicators. HDI and UBN have a similar spatial configuration while the LQI yields a more fragmented distribution associated to the complexity of its variables, dimension and weights.     

Analysing the Effect of Legal System on Corporate Social Responsibility (CSR) at the Country Level,from a Multivariate Perspective

In this paper, we analyse the effect of coercive isomorphism (legal system) on Corporate Social Responsibility (CSR) at the country level by using the multivariate statistical techniques X-STATIS and HJ-biplot, which allow us to capture the role that these institutional forces play in the evolution and patterns of behaviour regarding the commitment to sustainability. The results evidence that coercive forces have an important influence on the social and environmental commitment of companies. Analysis of the legal system shows that firms located in civil law countries have a greater interest in their CSR practices and in disclosing information than companies in common law countries; the most likely companies to act in a responsible way are those operating in institutional environments with a large and developed legal system oriented towards stakeholder protection. Consequently, our results show that companies operating in countries with similar legal systems adopt homogeneous patterns of behaviour regarding the commitment to sustainability, but their degrees of development are strongly determined by the coercive institutional characteristics.

LATIN AMERICA'S DECLINING SKILL PREMIUM: A MACROECONOMIC ANALYSIS

The decline in Latin America's skill premium and income inequality during the 2000s was partly driven by an economic expansion that favored low‐skill‐intensive service sectors. Evidence shows inequality becomes countercyclical in the 2000s, and unlike previous expansions, the boom was concentrated on services while manufacturing lagged behind. I build an open economy general equilibrium model that features a low‐skill‐intensive nontradable sector. The model suggests that favorable shocks to commodity prices and international interest rate spreads, such as those that buffeted Latin America in the 2000s, account for about a fifth of the observed decline in the skill premium.

FINANCIAL MARKETS' SHUTDOWN AND REACCESS

We employ a discrete‐time parametric duration model on a group of 121 countries over the period 1970–2011 and find that the probability of the end of financial markets' shutdown and reaccess falls as these events become longer. We also show that: (1) shutdown episodes are longer when economic prospects are poor and the degree of financial openness falls, the chief executive has been in office for long periods, and the country has a default history and (2) spells of reaccess tend to be longer when economic growth improves and financial openness increases, there are neither government crises nor government instability, and the country did not default in the past.

Exploring dialogic strategies in social media for fostering citizens’ interactions with Latin American local governments

Although the benefits of social media for enhancing citizens’ interactions with their local governments are well known in a more global context, few studies have focused on Latin America, or on the MERCOSUR countries in particular. This paper examines the use of dialogic strategies in the social media activities of local governments in MERCOSUR countries in order to generate citizens’ online engagement. Analysis of this question enhances our understanding of the use of social media by local governments in less developed countries and highlights the need for empirical evidence on the use of dialogic communication theory regarding stakeholder engagement with social media. The findings obtained reflect the positive influence of dialogic strategies on citizens’ online engagement, particularly those based on dialogic loop, useful information and generation of return visits, aimed at fostering participation via social media.     

Uses and abuses of culture: mestizaje in the era of multiculturalism

ABSTRACT

In this article, I analyse how intercultural ideas, practices and policies inform Mexico’s current racial formation, and how racial categories and meanings are shaped under neoliberalism and the politics of recognition. I argue that the uncritical use of cultural and ethnic differences as the central focus of interculturalism reifies and reproduces the preoccupation with culture and ethnic differences characteristic of the racial project of mestizaje that held sway for most of the twentieth century. This focus on difference has silenced a much-needed discussion about how neither interculturalism nor multiculturalism has changed existing racial hierarchies and privileges nor curtailed the effects of racism and racial injustice on indigenous people and their communities.
