Issues of educational support in primary school and secondary education in disadvantaged suburbs in France

From a critical sociological perspective, this article advances the debate between global schooling with political incentives and local meanings with localized educational practices and supports. It focuses on the role of education policies in the pursuit of social inclusion and social justice, but also shows how local actors adapt and experiment in managing the socio-cultural diversity of the students and the school contexts. First, I show the issues of educational support policies in the French context with a historical background and their re-appropriation by local actors. Second, I present the theoretical framework of my research (2008 to 2013), the methodology and initial results. Last, I analyze the main qualitative results of my comparative research in order to highlight ‘good’ or ‘bad’ educational support practices according to various criteria, starting with interactional socio-cultural posture between different actors.     

La construction des inégalités hommes-femmes dans l'entreprise. Une analyse de cas dans la métallurgie

Under the 1983 and 2001 laws on equality at the workplace, firms in France must submit to the works council a report “comparing the situations of men and women”. This report lays the groundwork for collective bargaining and remedial actions. Since this comparison is a snapshot at a year's interval from the previous report, it does not shed light on differences in occupational trajectories and opportunities; and it even risks masking the inequality between men and women. In contrast with the legally required report, a longitudinal analysis of data collected during a case study in a large metal-working firm shows that inequality has a long life and might be thriving. The company abides by the law but in an effort, it is hypothesized, not so much to reduce inequality between the sexes as to avoid lawsuits and prosecution.

Minimizing Skin Color Differences Does Not Eliminate the Own-Race Recognition Advantage in Infants

An abundance of experience with own-race faces and limited to no experience with other-race faces has been associated with better recognition memory for own-race faces in infants, children, and adults. This study investigated the developmental origins of this other-race effect (ORE) by examining the role of a salient perceptual property of faces-that of skin color. Six- and 9-month-olds' recognition memory for own- and other-race faces was examined using infant-controlled habituation and visual-paired comparison at test. Infants were shown own- or other-race faces in color or with skin color cues minimized in grayscale images. Results for the color stimuli replicated previous findings that infants show an ORE in face recognition memory. Results for the grayscale stimuli showed that even when a salient perceptual cue to race, such as skin color information, is minimized, 6- to 9-month-olds, nonetheless, show an ORE in their face recognition memory. Infants' use of shape-based and configural cues for face recognition is discussed.     

Optimal Insurance With Divergent Beliefs About Insurer Total Default Risk

This paper extends the classic expected utility theory analysis of optimal insurance contracting to the case where the insurer has a positive probability of total default and the buyer and insurer have divergent beliefs about this probability. The optimal marginal indemnity above the deductible is smaller (greater) than one if the buyer's assessment of default risk is more pessimistic (optimistic) than the insurer's. As an application of the model, we consider the market for reinsurance against catastrophic property loss and propose an expected utility theory explanation for the increasing and concave marginal indemnity schedule observed in this market.     

Social support networks,instant messaging,and gender equity in refugee education

ABSTRACT

This paper addresses the role of instant messaging chat groups to support teacher training and gender equity initiatives in Kenyan refugee camps. Our findings are based on survey data with refugee teachers in Dadaab and Kakuma refugee camps (n?=?203), group interviews with refugee teachers in Kakuma (n?=?21), and interviews with international instructors of teacher training programs in Nairobi, Toronto, and Vancouver (n?=?14). In our analysis, we apply amplification theory, feminist science and technology studies paradigms, and considerations of transnational approaches to understand the use of instant messaging among refugee teacher communities. Our framework explores how social and cultural norms are amplified through transnational text and instant messaging related to teacher training and in support of gender equity. Peer-to-peer group chats draw on transnational learning opportunities and expand these engagements through group chats between men and women refugee teachers across camps as well as through community engagement about gender equity initiatives in education. International instructors identify both value and hesitation in navigating the quantity and content of these communications, such as learning more about refugee teachers’ daily lives in the camps and concern about following and managing the amount of communication that can ensue over chat groups. Our work has practical implications for transnational teacher training programs in refugee camps, illuminates how mobile technology and chat groups allow women and men in the community to engage and support girls’ education, and questions how text messaging affects the lived and day-to-day experiences of women refugee teachers.     

Self-organizing maps in population based metaheuristic to the dynamic vehicle routing problem

We consider the dynamic vehicle routing problem (dynamic VRP). In this problem, new customer demands are received along the day. Hence, they must be serviced at their locations by a set of vehicles in real time. The approach to address the problem is a hybrid method which manipulates the self-organizing map (SOM) neural network into a population based evolutionary algorithm. The method, called memetic SOM, illustrates how the concept of intermediate structure, also called elastic net or adaptive mesh concept, provided by the original SOM can naturally be applied into a dynamic setting. The experiments show that the heuristic outperforms the approaches that were applied to the Kilby et al. 22 problems with up to 385 customers. It performs better with respect to solution quality than the ant colony algorithm MACS-VRPTW, a genetic algorithm, and a multi-agent oriented approach, with a computation time used roughly 100 times lesser.     

Computer experiments with functional inputs and scalar outputs by a norm-based approach

A framework for designing and analyzing computer experiments is presented, which is constructed for dealing with functional and scalar inputs and scalar outputs. For designing experiments with both functional and scalar inputs, a two-stage approach is suggested. The first stage consists of constructing a candidate set for each functional input. During the second stage, an optimal combination of the found candidate sets and a Latin hypercube for the scalar inputs is sought. The resulting designs can be considered to be generalizations of Latin hypercubes. Gaussian process models are explored as metamodel. The functional inputs are incorporated into the Kriging model by applying norms in order to define distances between two functional inputs. We propose the use of B-splines to make the calculation of these norms computationally feasible.     

Work/life balance policy in Germany: Promoting equal partnership in families

Across the OECD, public policies seek to support parents in achieving their desired work/life balance. This article introduces the background to and issues at stake in promoting equal partnerships in families in Germany. Families in Germany face considerable challenges to spending more time together and achieving a more gender‐balanced reconciliation of work and family life, as paid work hours for fathers are long on full‐time jobs and many women are in part‐time jobs. Family policy can play an important role and Germany has made substantial progress in supporting families ahead of and after the birth of a child. Important in this regard are the parental leave reforms of 2007 and 2015 and the extension of childcare supports that better enable fathers and mothers to combine work and family commitments. The article assesses recent developments in family policies in Germany while also drawing from the experiences of countries with longstanding policies to support work/life balance and strengthen gender equality.     

Post hoc false positive control for structured hypotheses

In a high-dimensional multiple testing framework, we present new confidence bounds on the false positives contained in subsets S of selected null hypotheses. These bounds are post hoc in the sense that the coverage probability holds simultaneously over all S, possibly chosen depending on the data. This article focuses on the common case of structured null hypotheses, for example, along a tree, a hierarchy, or geometrically (spatially or temporally). Following recent advances in post hoc inference, we build confidence bounds for some prespecified forest-structured subsets and deduce a bound for any subset S by interpolation. The proposed bounds are shown to improve substantially previous ones when the signal is locally structured. Our findings are supported both by theoretical results and numerical experiments. Moreover, our bounds can be obtained by an algorithm (with complexity bilinear in the sizes of the reference hierarchy and of the selected subset) that is implemented in the open-source R package sansSouci available from https://github.com/pneuvial/sanssouci , making our approach operational.
