Inequality of opportunity and (unequal) opportunities in the youth labour market: How is the Arab world different?

The Middle East and North Africa (MENA) labour market is emblematic of widespread youth unemployment and high discouragement rates, experiencing disproportionately high levels of unemployment among educated young people. Using ILO School-to-Work Transition Surveys for Egypt, Jordan and Tunisia, the authors explore whether this is related to inequality of opportunity or to deeper structural characteristics that create a mismatch between skill demand and supply on the labour market. The low availability of high-skilled jobs and the low value placed on skills gained through the system of vocational training are found to have high explanatory power.     

On the application of statistical learning approaches to construct inverse probability weights in marginal structural Cox models: Hedging against weight-model misspecification

The marginal structural Cox model (MSCM) estimates can be highly sensitive to weight-model misspecification. We assess the performance of various popular statistical learners, such as LASSO, support vector machines, CART, bagged CART, and boosted CART, in estimating MSCM weights. When weight-models are misspecified, we find that the weights computed from boosted CART generally lead to less MSE and better coverage for the MSCM estimates. This study is motivated by the investigation of the impact of beta-interferon treatment on disability progression in subjects with multiple sclerosis from British Columbia, Canada (1995–2008).     

Multivariate association test for rare variants controlling for cryptic and family relatedness

In genetic studies of complex diseases, multiple measures of related phenotypes are often collected. Jointly analyzing these phenotypes may improve statistical power to detect sets of rare variants affecting multiple traits. In this work, we consider association testing between a set of rare variants and multiple phenotypes in family‐based designs. We use a mixed linear model to express the correlations among the phenotypes and between related individuals. Given the many sources of correlations in this situation, deriving an appropriate test statistic is not straightforward. We derive a vector of score statistics, whose joint distribution is approximated using a copula. This allows us to have closed‐form expressions for the p‐values of several test statistics. A comprehensive simulation study and an application to Genetic Analysis Workshop 18 data highlight the gains associated with joint testing over univariate approaches, especially in the presence of pleiotropy or highly correlated phenotypes.

Why and how ontology matters: A cartography of neoliberalism(s) and neoliberalization(s)

In this article, I discuss the importance of ontology and its implications, demonstrated in the examples of different approaches to neoliberalism. The lack of careful ontological considerations leads to confusing and often contradictory usages of the term ‘neoliberalism’, obfuscating its usefulness. Instead, I suggest a cartography which consists of integrating two ontological debates - structure-agency and material-ideational - through the interplay between the problematiques of structuration and semiosis, and the operational debate on ideas/interests. In so doing, this cartography can provide readers with various heuristic devices to understand the making of theories, why and how conceptualizations of neoliberalism differ between and within theories and pinpoint the thematic implications of these differences. The translation of this cartography helps to achieve two things, (1) to move beyond the static analyses of neoliberalism and endorse the dynamic understand of neoliberalization processes, (2) to understand why systemic process-based understandings of neoliberalization can create distinctions between analytical understandings of neoliberalism in terms of either the commodification of marketization processes or the marketization of commodification processes.     

Disassembly of complex product structures with parts and materials commonality

This paper addresses the issue of parts and materials commonality when scheduling disassembly. In a disassembly environment, inventory management is complex due to the presence of multiple demand sources at the component level of the product structure. Commonality introduces a new layer of complexity by creating alternative procurement sources for the common component items. A novel scheduling algorithm is presented, followed by an example.     

Food Security: Rights, Livelihoods and the World Food Summit–Five Years Later

An international Summit was called for June 2002 aiming to reaffirm the commitments of the 1996 World Food Summit and intensify efforts to halve the number of hungry people in the world to 400 million by 2015. However, progress on achieving this target is open to question. This paper analyses recent policy debates in two areas: first, the right to food and freedom from hunger; and second, the measurement of food insecurity at global and national levels. It agrees that the "World Food Summit–five years later" (WFS–fyl) should reaffirm commitment to the right of all people to food and freedom from hunger and the commitment to raise the resources required to achieve this. A rights–based approach to food security implies that policies be defined and actions taken to reduce hunger by a range of local, non–governmental, governmental and international actors. However, reliable information on who the hungry are and where they are situated is required in order to track progress to WFS targets and identify and implement appropriate actions at the global, national or subnational levels. The inter–agency Food Insecurity and Vulnerability Information and Mapping Systems (FIVIMS) plays a key role in generating information on trends of the numbers of food–insecure in the world, but the robustness of its "undernourishment" measure has been debated. The paper concludes by outlining practical ways to improve food security analysis, indicating the potential contribution of rights–based and livelihoods approaches.     

Une privatisation inédite de la norme : le cas de la politique comptable européenne

EU member states have, for a long time, been harmonizing their accounting rules in order to facilitate comparisons among countries. A new regulation in 2002 has suddenly sped up this process. Under it, companies quoted in the stock exchange are, since 2005, required to comply with the standards set by the International Accounting Standards Board (IASB), a private body without any public mandate. After trying to harmonize its members’ standards, the EU’s decision to resort to private subcontracting is even more puzzling given the Union’s lack of any statutory control over the IASB. In this impressive case of the privatization of a regulatory process, attention is focused on the incorporation of IASB standards in EU law and on the structure and governance of this board. This transfer of power is much broader than usual forms of delegation to the private sector. Although several reasons underlie this relinquishment of public authority, the primary one lies within the EU itself.     

The effect of experience on faculty attitudes toward collective bargaining: A cross-temporal analysis

We used multivariate analysis to investigate the change in the attitudes and expectations of AAUP members in a Midwestern university. Two models were developed to measure faculty attitudes toward the union, at the time of the election and four years after the election. The effect of experience on faculty attitudes toward the union is captured by comparing the results of the two models. Our findings suggest major differences in faculty attitudes and expectations prior to and after the union’s arrival. The results of our study have essential policy implications for unions in formulating successful strategies and for faculty in developing realistic expectations of collective bargaining.
