Consumer Cooperatives: An Alternative Institutional Model for Delivery of Urban Water Supply and Sanitation Services?

This paper describes the essential characteristics of consumer cooperatives engaged in the provision of basic services and discusses their applicability as a model for water supply and sanitation service provision in urban areas. A cooperative is an autonomous association of persons united voluntarily to meet their common economic, social, and cultural needs and aspirations through a jointly-owned and democratically-controlled enterprise. The paper focuses on system-wide urban water supply cooperatives and it is thus not concerned with urban or peri-urban cooperatives that depend on either boreholes or bulk purchases of water from a utility for distribution, nor does it refer to rural water supply cooperatives that are generally small. After a general overview of cooperatives and a discussion of the main characteristics of utility cooperatives, the paper reviews the case of SAGUAPAC, a successful urban WSS cooperative in Bolivia, from which it draws some conclusions in the form of a preliminary assessment of cooperatives as a model for delivery of urban water supply and sanitation (WSS) services

CRiBAC: Community-centric role interaction based access control model

As one of the most efficient solutions to complex and large-scale problems, multi-agent cooperation has been in the limelight for the past few decades. Recently, many research projects have focused on context-aware cooperation to dynamically provide complex services. As cooperation in the multi-agent systems (MASs) becomes more common, guaranteeing the security of such cooperation takes on even greater importance. However, existing security models do not reflect the agents' unique features, including cooperation and context-awareness. In this paper, we propose a Community-based Role interaction-based Access Control model (CRiBAC) to allow secure cooperation in MASs. To do this, we refine and extend our preliminary RiBAC model, which was proposed earlier to support secure interactions among agents, by introducing a new concept of interaction permission, and then extend it to CRiBAC to support community-based cooperation among agents. We analyze potential problems related to interaction permissions and propose two approaches to address them. We also propose an administration model to facilitate administration of CRiBAC policies. Finally, we present the implementation of a prototype system based on a sample scenario to assess the proposed work and show its feasibility. © 2012 Elsevier Ltd. All rights reserved

The Role of Group Learning in Implementation of a Personnel Management System in a Hospital

A new HR system was introduced in a Dutch hospital. The system implied collaborative work among its users. The project planning seemed to be reasonably straightforward: the system's introduction was intended to take place gradually, including pilots in different departments and appropriate feedback. After some time, the system was successfully adopted by one group of users, but failed with another. We conceptualize the implementation process of groupware as group learning to frame the adoption of the system, and analyze the qualitative data collected during the longitudinal case study. We found that in the user group with strong group learning, adoption of the system occurred effectively and on time. In another user group with rather weak group learning, the use of the system was blocked after a short time. The results provided a first confirmation of our assumption about the importance of group learning processes in the implementation of groupware

The Public Face of the \u27Litigation State:\u27 Federal Empowerment of Litigation by State Governments

Scholars have recently begun exploring the construction of what Sean Farhang has termed the “litigation state” – namely, the distinctly American way in which contemporary federal programs are enforced by means of litigation. The attention in this literature to date has focused on why Congress has encouraged private litigation to enforce various statutory programs. This paper examines the emergence of a related and no less important development – the federal government’s encouragement of state government litigators to help enforce federal regulatory programs, especially state attorneys general ( AGs ). Examining several decades’ worth of congressional actions, court decisions, and federal administrative initiatives that have empowered state AGs, this paper explores how and why Congress and other federal institutions have placed increasing reliance on state AGs to enforce federal law. This question has become important not only because this federal empowerment has been a major driver of the prominent regulatory role state AGs have taken on in recent years, but because the political dynamic concerning state litigation differs from other aspects of the litigation state

Securing urban land for housing among low‐income earners in Sub‐Saharan Africa: Case study of workers’ co‐operative society, Enugu, Nigeria

Co‐operative societies across the world have age‐old tradition of assisting members gain easy access to vital resources and services through collective efforts. This paper explores the strategies adopted by public sector workers’ co‐operative society in securing urban land for housing development. This study is motivated by dearth of empirical studies on strategies used by low‐ and middle –income earners in overcoming myriad challenges militating against access to urban land and housing in Nigerian cities. We used a qualitative research method to carry out an empirical investigation through one‐on‐one interviews with purposively selected members of Land Acquisition Committee (LAC) of the NEPA District Co‐operative Thrift and Saving Loan Association Enugu, Nigeria. Findings show that a mixture of customary,informal and formal practices involved in securing land from indigenous landowners was principally aimed at ensuring customary and statutory legitimacy as well as secured tenure. The paper concludes that co‐operative approach has great potentials in addressing problems of multiple payments for land, “indigenous land owners’ factor” and high cost of urban land in Nigeria, and therefore, should be encouraged and promoted among disadvantaged urban residents in developing countries

Beyond aggression: Androgen-receptor blockade modulates social interaction in wild meerkats

In male vertebrates, androgens are inextricably linked to reproduction, social dominance, and aggression, often at the cost of paternal investment or prosociality. Testosterone is invoked to explain rank-related reproductive differences, but its role within a status class, particularly among subordinates, is underappreciated. Recent evidence, especially for monogamous and cooperatively breeding species, suggests broader androgenic mediation of adult social interaction. We explored the actions of androgens in subordinate, male members of a cooperatively breeding species, the meerkat (Suricata suricatta). Although male meerkats show no rank-related testosterone differences, subordinate helpers rarely reproduce. We blocked androgen receptors, in the field, by treating subordinate males with the antiandrogen, flutamide. We monitored androgen concentrations (via baseline serum and time-sequential fecal sampling) and recorded behavior within their groups (via focal observation). Relative to controls, flutamide-treated animals initiated less and received more high-intensity aggression (biting, threatening, feeding competition), engaged in more prosocial behavior (social sniffing, grooming, huddling), and less frequently initiated play or assumed a ‘dominant’ role during play, revealing significant androgenic effects across a broad range of social behavior. By contrast, guarding or vigilance and measures of olfactory and vocal communication in subordinate males appeared unaffected by flutamide treatment. Thus, androgens in male meerkat helpers are aligned with the traditional trade-off between promoting reproductive and aggressive behavior at a cost to affiliation. Our findings, based on rare endocrine manipulation in wild mammals, show a more pervasive role for androgens in adult social behavior than is often recognized, with possible relevance for understanding tradeoffs in cooperative systems
