Este estudo tem como finalidade analisar a possibilidade de implementação e integração do sistema de gestão da responsabilidade social numa empresa de engenharia e construção, de acordo com a norma NP 4469-1 (2008). Um dos objetivos deste trabalho é explorar uma das atividades fundamentais para o crescimento da economia: a construção. Esta funciona como barómetro da economia nacional, ou seja, movimenta vários setores importantes na sua cadeia de produção, contribuindo na criação de riqueza como também de emprego. Como consequência das mudanças na economia nos últimos anos, o comércio nacional transformou-se em comércio globalizado, tendo como mercado não só um país mas o mundo inteiro. As empresas veem isso como um desafio, independentemente da sua dimensão. A redução de custos e a diferenciação não podem ser a única fonte de competitividade. A recente situação de instabilidade económica mundial impulsiona as empresas a inovarem na sua imagem para com os stakeholders e, assim, garantir o seu desenvolvimento e sustentabilidade financeira. A temática da Responsabilidade Social Empresarial (RSE) surgiu da necessidade de existir um espírito empresarial responsável, ao encontro do conceito de desenvolvimento sustentável (Baylis e Smith, 2005). Apesar da ampla divulgação da noção de responsabilidade social das empresas, não se verifica, no entanto, uma definição exata da mesma, pois o tema tem sido abordado de diversas formas e tem dividido opiniões ao longo dos anos. A responsabilidade social é, assim, um fruto da gestão das organizações e das profundas críticas sociais, legais, éticas e económicas, inspiradas nos parâmetros da obtenção de valor social (Parra, 2003). A sustentabilidade revela uma mudança de paradigma do mundo empresarial, na medida em que as empresas devem adotar práticas socialmente responsáveis, que integrem de forma voluntária as preocupações ambientais, sociais e económicas no desenvolvimento das suas atividades operacionais e das suas interações com as partes interessadas.

As nonprofits do not have access to the same capital markets as for-profit enterprises, organizations usually scramble for funding to keep up with their mission. This scenario can be changed through the use of the right financial engineering. This Work Project aims at studying an innovative financing mechanism based on the concept of quasi-equity for organizations devoted to social ends to cope with their capital needs. A quasi-equity investment model is built for the Portuguese social business SPEAK, and an in-depth assessment of its current financial, organizational and impact situations is conducted. This is a pioneer case study in Portugal.

The present article is based on the MA thesis of Hou Bowen (Ph.D candidate) and on the presentation made at the ISA World Congress of Sociology held in Yokohama (Japan) on July 2014 at the Session on “Assessing Technologies: Global Patterns of Trust and Distrust” of RC23-Sociology of Science and Technology.

The regeneration of soft biological tissues requires new substitutes that exhibit mechanical properties similar to the native tissue. Herein, thin saloplastic membranes with tunable physical properties are prepared by complexation of chitosan and alginate solutions containing different concentrations of sodium chloride. Polyelectrolyte complexes (PECs) are transferred to flat Petri dishes for compaction into membrane shapes by sedimentation and solvent evaporation. All membranes are resistant to degradation by lysozyme and are stable in solutions with pH values between 1 and 13. Immersing the different membranes in new doping solutions of increasing salt concentrations triggers the typical saloplastic behavior, with a high water absorption and decrease of the rigidity and ultimate tensile strength. The range of such variations is tuned by the sodium chloride amount used in the synthesis: high salt concentrations increase water uptake and tensile moduli, while decreasing the ultimate strength. Cellular assays demonstrate high proliferation rates and viability of L929 fibroblasts seeded onto the most rigid membranes. The results validate the use of saloplastic membranes as soft tissue substitutes for future biomedical applications.

Firefly Algorithm is a recent swarm intelligence method, inspired by the social behavior of fireflies, based on their flashing and attraction characteristics [1, 2]. In this paper, we analyze the implementation of a dynamic penalty approach combined with the Firefly algorithm for solving constrained global optimization problems. In order to assess the applicability and performance of the proposed method, some benchmark problems from engineering design optimization are considered.

Este Working Paper tiene como objetivo identificar las nuevas formas de trabajo y tendencias emergentes en el campo de la construcción de la paz. El destinatario de este informe es el ICIP, por lo que las conclusiones están también enfocadas al plano operativo y a la posibilidad de integrar alguna de las prácticas descritas en su plan de actuación ordinaria. El texto presenta una serie de nuevas realidades emergentes, como el crowdfunding y el crowdsourcing, la transparencia financiera e informativa o el impacto de las redes sociales, que afectan a la forma en la que abordamos la construcción de la paz a nivel internacional. Cada tendencia viene acompañada de uno o varios ejemplos concretos que ayudan a comprender más fácilmente lo que está sucediendo en este terreno y qué podemos definir como innovación social.

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.
