The Sustainability has been evidence in the world today; organizations have sought to be more and more into this philosophy in their processes, whether products or attendance. In the present work were manufactured eco-composites with animal fiber (dog wool) that is currently discarded into the environment without any use. Project phases consisted on the initial treatment of fibers with alkaline solution (NaOH) at 0.05 mols for removal of impurities, developing methods to convert these fibers (reinforcement) blended with castor oil polyurethane (matrix) in eco-composite with different proportions (5%, 10%, 15% and 20%). Fiber properties were evaluated by analysis of SEM, XRD and FTIR. The composites were produced by compression molding with dimensions 30x30x1cm. For characterization of the composites the following tests were performed: mechanical (tensile, compression, shore hardness A) according the standards and testing water absorption, moisture regain and biodegradation. The analysis of thermal properties on fibers and composites were by TG, DSC, thermal conductivity, resistivity, heat capacity and thermal resistance. Analyzing the results of these tests, it was observed that the composite reinforced with 20% showed a better thermal performance between others composites and dimensional stability when compared to commercial thermal insulation. Also is possible to observe a balance in moisture absorption of the composite being shown with its higher absorption rate in this same sample (20%). The micrographs show the fiber interaction regions with polyurethane to fill the empty spaces. In hardness and compression testing can identify that with increasing percentage of the fiber material acquires a greater stiffness by making a higher voltage is used for forming necessary. So by the tests performed in eco-composites, the highest percentage of fiber used as reinforcement in their composition obtained a better performance compared to the remaining eco-composites, reaching values very close to the PU.

With the emergence of new technologies, has grown the need to use new materials, and this has intensified research on the collection and use of materials from renewable sources, is to reduce production costs and / or environmental impact. In this context, it was found that the sheath coconut straw, can be utilized as raw material for the production of a eco-composite that can be used as a thermal and acoustic insulator. After selected from the coconut sheaths were subjected to treatment with aqueous 2 % sodium hydroxide (NaOH). The composite study was produced with the sheath and coconut natural latex, with coconut sheath percentage in the proportions 15%, 25% and 35% of the total compound volume. Physical, thermal and acoustic properties of the composites were analyzed in order to obtain data on the use of viability as thermoacoustic insulation. The CP15 composites, CP25 and CP35 showed thermal conductivity 0.188 W/m.K, 0.155 W/m.K and 0.150 W/m.K, respectively. It can be applied as thermal insulation in hot systems to 200 ° C. The CP35 composite was more efficient as a thermal and acoustic insulation, providing 20% noise reduction, 31% and 34% for frequencies of 1 kHz, 2 kHz and 4 kHz, respectively. The analyzes were based on ABNT, ASTM, UL. Based on these results, it can be concluded that the eco-composite produced the hem of coconut can be used as thermal and acoustic insulation. Thus, it gives a more noble end to this material, which most often is burned or disposed of improperly in the environment.

Este trabajo analiza el funcionamiento del sistema de financiación de las Comunidades Autónomas de régimen común en España aprobado en la Ley 22/2009, desde la perspectiva específica del análisis de sus mecanismos de nivelación. Con esa finalidad,se propone una batería de indicadores de reordenación, indicadores de intensidad de la nivelación e indicadores de distorsiones de la nivelación que se aplica para la evaluación del desempeño del sistema vigente, en comparación con el aprobado en 2001, y que puede asimismo utilizarse para la evaluación de sistemas comparados. Los resultados ponen de manifiesto que el sistema aprobado en 2009 mejora el funcionamiento del sistema anterior, en la medida en que aumenta la intensidad de la nivelación y se reduce la prevalencia y la intensidad de las principales distorsiones que se detectaban en sus resultados de nivelación (reordenaciones. sobrenivelaciones y desnivelaciones).

Purpose: Eco-innovation is any form of product, process or organisational innovation that contributes towards sustainable development. Firms can eco-innovate in a variety of ways. The purpose of this paper is to identify nine different eco-innovation activities – including such items as reducing material use per unit of output, reducing energy use per unit of output, reducing carbon dioxide (CO2) “footprint” – and the authors ask whether these act as substitutes or complements to one another. Design/methodology/approach: Eco-innovation is any form of product, process or organisational innovation that contributes towards sustainable development. Firms can eco-innovate in a variety of ways. In this paper the authors identify nine different eco-innovation activities – including such items as reducing material use per unit of output, reducing energy use per unit of output, reducing CO2 “footprint” – and the authors ask whether these act as substitutes or complements to one another. Findings: Introducing only one eco-innovation activity has little payoff (in terms of turnover per worker) with only those firms who reduce their CO2 “footprint” having higher levels of turnover per worker. When introducing more than one eco-innovation activity the authors find that certain eco-innovation activities complement one another (e.g. reducing material use within the firm at the same time as improving the ability to recycle the product after use) others act as substitutes (e.g. reducing material use within the firm at the same time as recycling waste, water or materials within the firm). Practical implications: The results suggest that firms can maximise their productive capacity by considering specific combinations of eco-innovation. This suggests that firms should plan to introduce eco-innovation which act as complements, thereby, boosting productivity. It also suggests that eco-innovation stimuli, introduced by policy makers, should be targeted at complementary eco-innovations. Originality/value: The paper analyses whether eco-innovations act as complements or substitutes. While a number of studies have analysed the importance of eco-innovation for firm performance, few have assessed the extent to which diverse types of eco-innovation interact with each other to complement or substitute for one another.

Research in the fields of ceramic pigments is oriented towards the enlargement of the chromatic set of colors together with a replacement for more expensive and less stable organic pigments. Novel non-toxic inorganic pigments have been required to answer environmental laws to remove elements like lead, chromium, cobalt entering in the composition of usual pigments widely used in paints and plastics. Yellow is particularly an important color in the pigment industry and consumption of yellow exceeds that of any other colored pigments. Apart from this, high infrared reflective pigments are now in great demand for usage in coatings, cement pavements, automotives and camouflage applications. They not only impart color to an object, but also reflect the invisible heat from the object to minimize heat build–up, when exposed to solar radiation. With this in view, the present work aims at developing new functional yellow pigments for these applications. A series of IR reflecting yellow pigments have been synthesized and analyzed for their crystalline structure, morphological, composition and optical characteristics, coloring and energy saving applications

As the demand for environmentally sustainable tourism grows, eco-labels are becoming increasingly popular as a signal of environmental quality. However, the existence of a causal link between awarding a seaside eco-label and the increase in tourism flows is still under discussion in the literature. In this article, we gauge the signalling impact of a specific eco-label, the Blue Flag award, using detailed data on tourism flows to seaside Italian destinations during the period 2008-2012. We adopt a recent econometric modelling strategy - the synthetic control method - in shaping estimation results and testing the sensitivity and robustness of our results. We find that being awarded the Blue Flag increases the flow of domestic tourists for up to three seasons after assignment. However, we find no effect for the flow of international tourists. Investigating the mechanisms driving the results, we find that the award of a Blue Flag only positively affects the flow of domestic tourists when it is used as a driver of organisation, coordination and integrated management of the tourism supply.

A presente dissertação pretende avaliar como os membros das organizações relacionam a prática das danças circulares com elementos do comportamento organizacional. A pertinência desta investigação consiste no fato de estudos e intervenções direcionadas ao comportamento organizacional poderem impactar positivamente o desempenho tanto dos servidores quanto da organização como um todo. As organizações estão enfrentando desafios que demandam teorias e práticas que as fortaleçam, buscando-se atender às necessidades de todos que a compõe. A profundidade dessas mudanças faz com que seja necessário alinhar-se o esforço individual ao grupal. Necessita-se o aprendizado em grupo, o pensamento sistêmico. As danças circulares parecem proporcionar efeitos de bem-estar, segurança, solicitude, cooperação, abertura ao diálogo e eles são extremamente importantes em relação a diversos aspectos da organização, como liderança, hierarquia, motivação, poder, clima organizacional, cultura, comunicação, etc. Seus efeitos, por conseguinte, podem fazê-las importante instrumento que melhore os ambientes de trabalho, além de proporcionarem uma conscientização quanto à importância de levar às organizações o tema da sustentabilidade. A sustentabilidade insere-se no paradigma eco-humanista, alinhado, por sua vez, ao resgate da inteireza do homem. As danças circulares, podem expressar e materializar tal paradigma, de modo a favorecer o comprometimento, a motivação e a participação nas organizações. / This dissertation aims evaluate how the members of organizations relate the practice of circle dances with elements of organizational behavior. Its importance derives in the fact that studies and interventions addressed to the organizational behavior may impact positively both the performance of the workers as well of the organization as a whole. The organizations are facing challenges that need theories and practices to strengthen them, in order to fill the needs of all its members. The depth of the changes makes it necessary to encompass the individual and the grupal efforts. It is necessary the group learning and the systemic thinking. The circle dances seems to provide effects such as well being, security, solicitude, cooperation, openness to dialogue and they are extremely important related to various aspects of organization, as leadership, hierarchy, motivation, power, organizational climate, culture, communication, etc. Its effects, thus, may make them important tool to the betterment of the work environment, besides allow the awareness of the importance to bring to organizations the theme of sustainability. The sustainability is a part of the eco-humanistic paradigm, related to the integrity of man. The circle dance may express and materialize this paradigm, helping commitment, motivation and participation in the organizations.

The authors investigated (a) the relationship between feeling connected to nature and pro-environmental behaviours; and (b) the relationship between environmental values and environmental behaviours. Seventy-six students completed an online survey that measured connectedness to nature, egoistic, altruistic and biospheric values, and pro-environmental behaviours. This study suggests that finding ways to increase community feelings of connectedness to nature, and developing altruistic and biospheric values may lead to increased pro-environmental behaviours in the short term and positively address climate change issues in the longer term.

Il mio elaborato ha come scopo quello di creare un quadro della situazione regionale dal punto di vista delle start-up eco-innovative. Per fare questo ho utilizzato un sito/piattaforma internet contenente il registro delle start-up innovative in Italia. A partire da tale supporto ho analizzato 700 start-up situate nella regione Emilia-Romagna. Tra queste, ho individuato 78 start-up eco-innovative. Lo studio vuole comprendere le tendenze e la diffusione di tali start-up, studiandone, nell' ordine, la distribuzione geografica, l’inizio delle attività, il codice Ateco, la tecnologia OECD di riferimento. Con questo studio si arriverà poi in definitiva a capire quanto l’ambito della Green Economy sia diffuso in Emilia-Romagna.
