Emotions in context: Revolutionary accelerators,hope, moral outrage,and other emotions in the making of Nicaragua's revolution

Building on the social movement/revolutions and recent social movement emotions literature and using interviews and oral history from revolutionary Nicaragua, I make a case for recognizing the significance of emotions when studying revolutions. The essay aims for a contextual understanding of the role of emotions in the making of revolution during the insurrectionary period in Nicaragua. These are examined from the vantage point of revolutionary accelerators the conflictual event-contexts from which revolutionary actors emerge. Through the historical analysis of testimonies associated with a number of politically significant events that changed the course of political dynamics in 1970s Nicaragua, the piece illustrates: (1) how events function as generators of revolutionary action and (2) how event-related emotions such as anger and fear, but primarily moral outrage and hope, contribute to a transformation in consciousness that leads potential participants to define their circumstances as needing their revolutionary involvement. It also attempts to demonstrate how the latter two emotions—moral outrage and hope—are dominant under different event-contexts. Lastly, the relationships between these emotions and how these are connected to revolutionary accelerators are similarly explored.     

The ‘compliant’, the ‘pacified’ and the ‘rebel’: experiences with Swiss disability insurance

Switzerland’s social policies in the field of disability have been significantly reshaped over the last two decades by reducing the number of allowances awarded and by increasing the recourse to vocational rehabilitation measures. What stances do individuals who experience the implementation of these policies adopt? What kind of tests are they subjected to? How can we explain the posture they adopt – be it ‘compliant’, ‘pacified’ or ‘rebellious’ – when facing the (re)assignations of their identity and professional status? Drawing on interviews conducted with individuals who have recently been involved in programmes set up by Swiss disability insurance, we highlight their uncertainties and concerns relating to their place in society, as well as their reactions to disability insurance’s interventions.     

Focused information criterion for locally misspecified vector autoregressive models

This paper investigates the focused information criterion and plug-in average for vector autoregressive models with local-to-zero misspecification. These methods have the advantage of focusing on a quantity of interest rather than aiming at overall model fit. Any (su?ciently regular) function of the parameters can be used as a quantity of interest. We determine the asymptotic properties and elaborate on the role of the locally misspecified parameters. In particular, we show that the inability to consistently estimate locally misspecified parameters translates into suboptimal selection and averaging. We apply this framework to impulse response analysis. A Monte Carlo simulation study supports our claims.     

Public-Private Wage Differentials in French-Speaking Africa: A Comparative Analysis

Abstract. In the framework of structural adjustment programs implemented in Africa, the idea that wages in the public sector are too high compared to those of the private sector is partly based on wage policies with regard to the public sector. But the existence of public-wage differentials, inducing a labour market segmentation within the modern sector, has rarely been the object of attentive examination. With the help of earnings functions, based on homogeneous cross-section and logitudinal data of seven capitals of French-speaking Africa, the author plans to verify this hypothesis. The main conclusion of this research is that distortions on the modern labour market of many African countries are less important than one may think. In most of the countries considered, public-private wage gaps are essentially attributable to characteristics of individuals. This suggests that policies aiming to reduce wages of the public sector are no longer justifiable, economically and socially.     

Automatic anthropometric personalization of a digital human model from a set of subject's photographs

The objective of the work is to develop a method for automatic dimensioning of a digital human model (DHM) from a set of calibrated photographs of the subject under study. Fifteen subjects (10 males, 5 females, mean age 27) wearing surface retro-reflective markers at major bony landmarks and standing inside a calibrated space, were photographed by means of low cost main stream digital cameras (face, left and right views). The DHM software used is based on a skeletal structure surrounded by contours defined by cross sections along the skeletal links. Specific points corresponding to bony landmarks are defined in body linkage local reference frames. The photograph calibration method (DLT) allows to superimpose a picture of the DHM on the subject's photographs. A specific algorithm adjusts the length of the manikin skeletal links in function of the measured distance between markers attached to these links (e.g. knee and ankle for the lower leg). Then the contour sections dimensions were adjusted to fit subject's silhouette extracted from the photographs. The results obtained within a few seconds of calculation consist of a personalized DHM representing the subject with an error less than 2% for stature and less than 4% for weight.     

Local perception of rodent-associated problems in Sahelian urban areas: a survey in Niamey,Niger

Rodents are involved in the epidemiology of many pathogens and are major pests for agriculture. Local perception and beliefs about rodents and their damages is a key element of control programs. We here present the first survey focusing on the human perception of rodent-associated problems in an African town, namely Niamey, Niger. In total, 170 interviews were conducted in 18 different urban districts where rodents (Mastomys natalensis, Rattus rattus and Mus musculus) are widespread and abundant. Rodent-associated problems were mentioned in almost all instances (96.5 %). Eight different categories of rodent-induced nuisances could be recurrently identified. The most frequently cited one consists in damages on food and food stocks (63.1 %), followed by damages on houses (47.3 %), furniture (19.5 %) and clothes (16.8 %). There was no significant association between damages and districts, which means that the perception of rodent-associated problems did not vary significantly across the city. Our survey strongly suggests that rodents may represent major pests not only for farmers, but also for inhabitants of towns, thus contributing to reinforce economic vulnerability. Finally, no mention of sanitary or medical problems was ever recorded during our survey, thus pointing towards an apparent absence of knowledge about the potential role of rodents in some public health issues.     

Anxiety,Depression and Fraternal Experiences on the Birth Child in a Foster Home

If foster care primarily concerns foster children displaced from a family to another, it also constitutes a singular event for the entire family, including the children of the foster parents. The aim of this study was to examine anxiety and depressive symptoms in foster families’ birth children and to explore the statistical associations between the different types of horizontal relations (with a sibling or a foster child) and the psycho-affective equilibrium of the birth children. Self-evaluation scales on the quality of sibling relations, anxiety and depressive symptoms were used. Forty five birth adolescents, aged from 11 to 18 years old, took part in the study. These participants showed more balanced scores of anxiety and depression than the population of the same age. Post-hoc tests additionally suggest that these ones vary depending on the gender, possibly due to specific role expectations. The relations between siblings or with the foster child present differentiated outcomes on anxiety and depression scores. This study confirms that the quality of horizontal relations is important for the psycho-affective equilibrium of the birth child. The relationships between birth and foster children need to be more systematically considered in order to promote successful fostering.     

Functional convergence of quantile-type frontiers with application to parametric approximations

Nonparametric estimators of the upper boundary of the support of a multivariate distribution are very appealing because they rely on very few assumptions. But in productivity and efficiency analysis, this upper boundary is a production (or a cost) frontier and a parametric form for it allows for a richer economic interpretation of the production process under analysis. On the other hand, most of the parametric approaches rely on often too restrictive assumptions on the stochastic part of the model and are based on standard regression techniques fitting the shape of the center of the cloud of points rather than its boundary. To overcome these limitations, Florens and Simar [2005. Parametric approximations of nonparametric frontiers. J. Econometrics 124 (1), 91–116] propose a two-stage approach which tries to capture the shape of the cloud of points near its frontier by providing parametric approximations of a nonparametric frontier. In this paper we propose an alternative method using the nonparametric quantile-type frontiers introduced in Aragon, Daouia and Thomas-Agnan [2005. Nonparametric frontier estimation: a conditional quantile-based approach. Econometric Theory 21, 358–389] for the nonparametric part of our model. These quantile-type frontiers have the superiority of being more robust to extremes. Our main result concerns the functional convergence of the quantile-type frontier process. Then we provide convergence and asymptotic normality of the resulting estimators of the parametric approximation. The approach is illustrated through simulated and real data sets.
