An Age-Period-Cohort Approach to Analyse Late-Life Depression Prevalence in Six European Countries, 2004–2016

European Journal of Population - Late-life depression is a condition that affects an ever-growing share of the population in ageing societies. While depression prevalence varies across countries...     

Les transformations de l'intégration par l'emploi: Regards croisés : France métropolitaine - île de La Réunion

Against a background of mass unemployment and the increasing precariousness of employment, the current changes in the labour market demand that we examine the previously central role of paid employment in social integration. If the individual now deprived of employment or having a temporary contract is by dint of this fact less included in society or is less secure by not having a permanent salary, is it to say that he embodies the face of the de-affiliated, of those who miss out on social benefits? Taking the example of the Reunion Island which has the highest level of unemployment and population covered by the minimum income (RMI: Revenu Minimum d'Insertion) in the country, this article endeavours to explain and understand how, in the context of a protective society and increasingly flexible employment market, new methods of social integration without and resulting from paid employment are being formed.     

Uniform asymptotic linearity of a process based on a signed rank statistic

Consider the process with, cf. (1.2) on page 265 in B1, X₁, …, X_N a sample from a distribution F and, for i = 1, …, N, R${}_{\text{|x}{}_{\text{1}}\text{, - q}{}_{\text{1}}\text{ø|}}$ , the rank of |X₁ - q₁ø| among |X₁ - q₁ø|, …, |X_N - q_Nø|. It is shown that, under certain regularity conditions on F and on the constants p_i and q_i, T^ø_N(t) is asymptotically approximately a linear function of ø uniformly in t and in ø for |ø| ≤ C. The special case where the p_i and the q_i, are independent of i is considered.     

CEO Reciprocal Interlocks in French Corporations

In France the chairperson of the board is mostoften the firm's CEO. This position strengthensthe insiders' hold on the board of directors.Moreover, a large fraction of outside directorsis composed of CEOs of other firms. Thereciprocal interlocking of CEOs creates the possibility of mutual interdependence of CEOs.We investigate factors explaining reciprocalinterlocking directorates of CEOs in Frenchcorporations. Our results indicate that CEOs oflarger firms hold more reciprocal CEOinterlocks and when CEOs have more outsidedirectorships, CEOs hold more reciprocalrelationships. We also find a positiverelationship between the number of CEOsreciprocal interlocks and their firms'performance measured by ROA. We find evidencethat CEOs hold more reciprocal interlocks whena blockholder is present on the CEO's board.     

On Combining Wavelets Expansion and Sparse Linear Models for Regression on Metabolomic Data and Biomarker Selection

Wavelet thresholding of spectra has to be handled with care when the spectra are the predictors of a regression problem. Indeed, a blind thresholding of the signal followed by a regression method often leads to deteriorated predictions. The scope of this article is to show that sparse regression methods, applied in the wavelet domain, perform an automatic thresholding: the most relevant wavelet coefficients are selected to optimize the prediction of a given target of interest. This approach can be seen as a joint thresholding designed for a predictive purpose. The method is illustrated on a real world problem where metabolomic data are linked to poison ingestion. This example proves the usefulness of wavelet expansion and the good behavior of sparse and regularized methods. A comparison study is performed between the two-steps approach (wavelet thresholding and regression) and the one-step approach (selection of wavelet coefficients with a sparse regression). The comparison includes two types of wavelet bases, various thresholding methods, and various regression methods and is evaluated by calculating prediction performances. Information about the location of the most important features on the spectra was also obtained and used to identify the most relevant metabolites involved in the mice poisoning.     

Impact of physical activity on activity of daily living in moderate to severe dementia: a critical review

The objectives of this study were to describe the different modalities of physical activity programs designed for moderate to severe dementia and to identify their impact on functional independence in activities of daily living (ADL). A critical review of randomized controlled trials related to the impact of physical activity programs in moderately to severely demented persons on ADL performance and meta-analysis of the identified studies were performed. Among the 303 identified articles, five responded to the selection criteria. Four out of the five studies demonstrated limited methodological quality. In one high-quality study, physical activity programs significantly delayed deterioration of ADL performance. The program components and ADL assessment tools vary widely across studies. Although the proposed treatments have not proven their efficiency in improving the ADL status of the patients, they were able to limit the decline in ADL functioning. Future research is warranted in order to identify clinically relevant modalities for physical activity programs for people with moderate to severe dementia.     

CONTROL: the extractive ecology of corn monoculture

This article tells the history of the industrial and biotechnological development of large-scale corn agriculture, from a new materialist perspective. Addressing the large-scale economy of industrial food production as a form of more-than-human configuration, it demonstrates how corn has been made into a quintessential commodity and factor of production for a consumption-based economy. Set within discourses around the climate crisis, this account critically assesses the Anthropocene and its advocacy for human accountability in regards to the exploitation of nonhuman matters. I ask: who is the Anthropos? How does it/he/she meet with its domesticated subjects, or rather makes them into domesticable materials? Telling the history of corn monoculture from a new materialist standpoint exposes this industry’s distribution of agency, power and control across a diversity of human and nonhuman actors. This is at the centre of this article’s three sections: (1) an argument for inscribing extractivism within new materialist literature, (2) an account of the industrialization of corn monoculture, exposing the industry’s main mechanisms and economic endeavours, as well as its ramifications with a biopolitics of invasion and (3) the biotechnological development of the industry and its shifts from a biopolitics of vegetal matter to an informational extractivism and a necropolitics of killable life. Thus I argue that if the industry of corn monoculture belongs to a broader network of detrimental industries characteristic of the Anthropocene, the geological Anthropos is not to be understood as synonymous with the human species, but as a very restrictive ecology of humans and nonhumans, including corporate, industrial, technoscientific and extractive actors. As such, the article emphasizes the moral necessity of rupturing with the narrative of the Anthropocene, a discourse better suited for supporting existing mechanisms of domination and exploitation constitutive of the economy of climate change.
