The generation and re-generation of social capital and enterprises in multi-stakeholders social cooperative enterprises: a system dynamic approach

Theories on social capital and on social entrepreneurship have mainly highlighted the attitude of social capital to generate enterprises and to foster good relations between third sector organizations and the public sector. This paper considers the social capital in a specific third sector enterprise; here, multi-stakeholder social cooperatives are seen, at the same time, as social capital results, creators and incubators. In the particular enterprises that identify themselves as community social enterprises, social capital, both as organizational and relational capital, is fundamental: SCEs arise from but also produce and disseminate social capital. This paper aims to improve the building of relational social capital and the refining of helpful relations drawn from other arenas, where they were created and from where they are sometimes transferred to other realities, where their role is carried on further (often working in non-profit, horizontally and vertically arranged groups, where they share resources and relations). To represent this perspective, we use a qualitative system dynamic approach in which social capital is measured using proxies. Cooperation of volunteers, customers, community leaders and third sector local organizations is fundamental to establish trust relations between public local authorities and cooperatives. These relations help the latter to maintain long-term contracts with local authorities as providers of social services and enable them to add innovation to their services, by developing experiences and management models and maintaining an interchange with civil servants regarding these matters. The long-term relations and the organizational relations linking SCEs and public organizations help to create and to renovate social capital. Thus, multi-stakeholder cooperatives originated via social capital developed in third sector organizations produce new social capital within the cooperatives themselves and between different cooperatives (entrepreneurial components of the third sector) and the public sector. In their entrepreneurial life, cooperatives have to contrast the "working drift," as a result of which only workers remain as members of the cooperative, while other stakeholders leave the organization. Those who are not workers in the cooperative are (stake)holders with "weak ties," who are nevertheless fundamental in making a worker's cooperative an authentic social multi-stakeholders cooperative. To maintain multi-stakeholder governance and the relations with third sector and civil society, social cooperatives have to reinforce participation and dialogue with civil society through ongoing efforts to include people that provide social proposals. We try to represent these processes in a system dynamic model applied to local cooperatives, measuring the social capital created by the social cooperative through proxies, such as number of volunteers and strong cooperation with public institutions. Using a reverse-engineering approach, we can individuate the determinants of the creation of social capital and thereby give support to governance that creates social capital.

The appropriateness of renal angioplasty: the ANPARIA software: a multidisciplinary expert panel approach

Percutaneous transluminal renal angioplasty (PTRA) is an invasive technique that is costly and involves the risk of complications and renal failure. The ability of PTRA to reduce the administration of antihypertensive drugs has been demonstrated. A potentially greater benefit, which nevertheless remains to be proven, is the deferral of the need for chronic dialysis. The aim of the study (ANPARIA) was to assess the appropriateness of PTRA to impact on the evolution of renal function. A standardized expert panel method was used to assess the appropriateness of medical treatment alone or medical treatment with revascularization in various clinical situations. The choice of revascularization by either PTRA or surgery was examined for each clinical situation. Analysis was based on a detailed literature review and on systematically elicited expert opinion, which were obtained during a two-round modified Delphi process. The study provides detailed responses on the appropriateness of PTRA for 1848 distinct clinical scenarios. Depending on the major clinical presentation, appropriateness of revascularization varied from 32% to 75% for individual scenarios (overal 48%). Uncertainty as to revascularization was 41% overall. When revascularization was appropriate, PTRA was favored over surgery in 94% of the scenarios, except in certain cases of aortic atheroma where sugery was the preferred choice. Kidney size [7 cm, absence of coexisting disease, acute renal failure, a high degree of stenosis (C70%), and absence of multiple arteries were identified as predictive variables of favorable appropriateness ratings. Situations such as cardiac failure with pulmonary edema or acute thrombosis of the renal artery were defined as indications for PTRA. This study identified clinical situations in which PTRA or surgery are appropriate for renal artery disease. We built a decision tree which can be used via Internet: the ANPARIA software (http://www.chu-clermontferrand.fr/anparia/). In numerous clinical situations uncertainty remains as to whether PTRA prevents deterioration of renal function.

A relação entre a satisfação dos funcionários e a satisfação dos clientes: estudo nas empresas de software do município de Belo Horizonte

A indústria de software tem apresentado crescimento vigoroso nos últimos anos, não só em termos mundiais, como também no Brasil. O segmento é composto basicamente por empresas de pequeno porte, com utilização intensiva de mão de obra especializada. No entanto, estudos indicam que o setor pouco se preocupa com a qualificação de funcionários, talvez porque, normalmente, a demanda supere a oferta, o que relega a um plano secundário as preocupações com a gestão de pessoas, ficando as atenções voltadas para o desenvolvimento e a formatação do serviço propriamente dito. Segundo os modelos teóricos, a participação dos funcionários é de vital importância para o fornecimento de um serviço de qualidade, podendo acarretar a satisfação dos clientes, sua lealdade e, consequentemente, incrementar a rentabilidade da organização. A satisfação dos funcionários pode ser alcançada pela introdução de práticas adequadas de gerenciamento de recursos humanos, incluindo boa comunicação, treinamento e desenvolvimento, trabalho em equipe, incentivo à participação e poder de decisão. Diversos modelos foram propostos para avaliar a satisfação dos clientes, a qual é fruto da qualidade percebida do serviço, de suas expectativas e do valor percebido, de acordo com um dos modelos em questão. Alguns estudos relatam a existência de relação positiva e significativa entre satisfação de clientes e de funcionários. Nesse contexto, procurou-se avaliar qual o impacto da satisfação dos funcionários diretamente sobre a satisfação dos clientes, com base em um modelo teórico que integrasse práticas de Recursos Humanos e antecedentes da satisfação dos clientes. Por meio de pesquisa quantitativa, foram entrevistados clientes e funcionários de 50 empresas da indústria de software de Belo Horizonte (Minas Gerais, Brasil), totalizando uma amostra válida de 147 respondentes para cada grupo. Os dados foram avaliados com o recurso da modelagem de equações estruturais, pelo método dos mínimos quadrados parciais. Com base nos resultados obtidos, infere-se que as melhores práticas de Recursos Humanos realmente influenciam a satisfação dos funcionários e que a qualidade percebida do serviço influencia positivamente a satisfação dos clientes. Contudo, não se constatou relação significativa entre a satisfação dos funcionários e a satisfação dos clientes.

GesRetail : software de gestión integral

El proyecto surge con el fin de crear una aplicación que responda a las necesidades de gestión y control de las actividades que se desarrollan en empresas minoristas dedicadas al sector de la electrónica de consumo. Este tipo de establecimientos aunque están muy especializados y proporcionan un trato excelente al público, suelen tener deficiencias técnicas a la hora de gestionar y controlar su negocio. Muchos de ellos carecen de programas informáticos adaptados a sus necesidades, e incluso en algún caso no disponen de ninguno por el alto coste que les supone. Dicho software tiene dos objetivos: por un lado atender las necesidades de este sector y por otro que el desembolso de la adquisición e implantación del mismo sea asequible. Para conseguir este último objetivo se utilizará software libre.

A New Imaging Software To Evaluate The Centration Of Capsulorhexis And Intraocular Lens (IOL) After Cataract Surgery

Purpose: IOL centration and stability after cataract surgery is of high interest for cataract surgeons and IOL-producing companies. We present a new imaging software to evaluate the centration of the rhexis and the centration of the IOL after cataract surgery.Methods: We developed, in collaboration with the Biomedical Imaging Group (BIG), EPFL, Lausanne, a new working tool in order to assess precisely outcomes after IOL-implantation, such as ideal capsulorhexis and IOL-centration. The software is a plug-in of ImageJ, a general-purpose image processing and image-analysis package. The specifications of this software are: evaluation of the rhexis-centration and evaluation the position of the IOL in the posterior chamber. The end points are to analyze the quality of the centration of a rhexis after cataract surgery, the deformation of the rhexis with capsular bag retraction and the centration of the IOL after implantation.Results: This software delivers tools to interactively measure the distances between limbus, IOL and capsulorhexis and its changes over time. The user is invited to adjust nodes of three radial curves for the limbus, rhexis and the optic of the IOL. The radial distances of the curves are computed to evaluate the IOL implantation. The user is also able to define patterns for ideal capsulorhexis and optimal IOL-centration. We are going to present examples of calculations after cataract surgery.Conclusions: Evaluation of the centration of the rhexis and of the IOL after cataract surgery is an important end point for optimal IOL implantation after cataract surgery. Especially multifocal or accommodative lenses need a precise position in the bag with a good stability over time. This software is able to evaluate these parameters just after the surgery but also its changes over time. The results of these evaluations can lead to an optimizing of surgical procedures and materials.

The role of energetic value in dynamic brain response adaptation during repeated food image viewing.

The repeated presentation of simple objects as well as biologically salient objects can cause the adaptation of behavioral and neural responses during the visual categorization of these objects. Mechanisms of response adaptation during repeated food viewing are of particular interest for better understanding food intake beyond energetic needs. Here, we measured visual evoked potentials (VEPs) and conducted neural source estimations to initial and repeated presentations of high-energy and low-energy foods as well as non-food images. The results of our study show that the behavioral and neural responses to food and food-related objects are not uniformly affected by repetition. While the repetition of images displaying low-energy foods and non-food modulated VEPs as well as their underlying neural sources and increased behavioral categorization accuracy, the responses to high-energy images remained largely invariant between initial and repeated encounters. Brain mechanisms when viewing images of high-energy foods thus appear less susceptible to repetition effects than responses to low-energy and non-food images. This finding is likely related to the superior reward value of high-energy foods and might be one reason why in particular high-energetic foods are indulged although potentially leading to detrimental health consequences.
