This paper aims to reflect on the work of Virginia E. Schein and her paper “The functions of work‐related group participation for poor women in developing countries: an exploratory look.”

Professor Schein traveled to Nicaragua, to lower‐income settings, where she observed and recorded the experiences of women working in self‐organized groups, and used those observations to argue to the profession generally that self‐organized groups of women, however marginal the work itself, can be instrumental in developing the key sense of agency, and self‐efficacy. These are basic capabilities; the stuff of the Millennium Development Goals.

For this special issue, therefore, the authors have made Schein's 2003 study a focal point. To set the context they asked Dr Schein to reiterate the rationale for the research, and provide a brief overview of the original observations. To help expand the debate on gender, work and poverty reduction, the authors have asked noted colleagues to provide a series of Commentaries on the original article.

Women, especially those raising children alone, are among the poorest of the poor in developing and more developed economies. Research that is applicable and relevant to their work‐related concerns can and should be a larger part of worldwide efforts to reduce poverty. Organizational psychology has much to contribute to those long‐overdue efforts.

The guest editorial seeks to introduce the papers in this special issue, which focus on the contribution which industrial and organizational psychology can make towards poverty reduction. It also aims to suggest future research directions.

The paper begins by offering a broad conceptualization of how industrial and organizational psychology can frame an approach towards poverty reduction. The second part gives a brief outline of each paper in the special issue.

This special issue brings together studies which generally focus on aspects of the aid worker experience, addressing adjustment issues for international aid workers, relationships between workers, and the value of self‐organizing and social support.

Factors, which could hinder aid workers from achieving their goals, are a common theme across the papers. Variables, which need to be considered, scales, which could be adopted for measuring key issues, and policy issues, which aid organizations need to consider, are discussed.

The paper highlights how industrial and organizational psychology can contribute to poverty reduction.

Avant‐propos sous les auspices de l'Institut international de Coopération intellectuelle, paraissait en 1934 le t. I, consacré à l'Europe, du Guide international des Archives. Le questionnaire envoyé à tous les États européens comportait sous les points 4 et 6 les questions suivantes: ‘Existe‐t‐il un guide général pour les diverses catégories d'Archives ou des guides particuliers pour l'une ou l'autre d'entre elles?’ et ‘Existe‐t‐il des catalogues imprimés, des publications tant officielles que privées, susceptibles de constituer un instrument complet de référence pour tout ou partie importante des fonds d'archives?’ Les réponses des divers pays à ces questions, malgré leur caractère très inégal, ont fait du Guide international un bon instrument d'information générale sur les Archives. Malheureusement les circonstances ont empêché la publication du volume consacré aux États non européens, tandis que le temps qui s'écoulait tendait à rendre périmés les renseignements fournis sur les Archives européennes.

Finer sediment particles (silt and clay) transported by rivers carry the major part of nutrient loads by absorption; thus, sediment settling can remove nutrients from the water column. The purpose of this paper is to analyze the relation between reservoir sedimentation and water quality by assessing the reservoir sedimentation process and the sediments’ characteristics.

Bathymetric surveys from 2004 to 2014 were analyzed to assess the sedimentation process. Core samples provided information on a layer-by-layer basis of the sediment deposits, and water samples near the surface and near the bottom provided information on sediment concentration, and adsorbed and dissolved nutrients.

The upstream region of a reservoir is already silted. From 2004 to 2014, the delta evoluted approximately 500 m downstream and the deposits were mainly composed of clay. An area of approximately 1,000 m between the delta and the dam should still be able to continue allowing sediment deposition in the coming years. Most of the nutrients were absorbed into the sediment particles, except for the nitrogen measured in the dry season.

Although analyses of the full cycle of the nutrients were not carried out, the constant sediment trapping of finer sediments and the high rate of absorbed nutrients in the suspended sediment support the hypothesis that the reservoir has removed nutrients from aqueous media by adsorption into sediments.

In the studied case, reservoir sedimentation has led to better water quality downstream.

It is shown in this study that reservoir sedimentation may have positive effects on river water quality.
