Obtenção e caracterização de um eco-compósito à base de látex e bainha da palha do coqueiro para isolamento térmico e acústico

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.

Eco-innovation – does additional engagement lead to additional rewards?

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.

Synthesis and characterization of eco-friendly inorganic yellow pigments for coloring applications

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

The signalling effect of eco-labels in modern coastal tourism

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.

Danças Circulares e o Eco-humanismo nas Organizações

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.

How Can Villages Become Eco-villages?

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.

La diffusione delle start-up eco-innovative in Emilia-Romagna

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.

Can You Hear the Eco? : A Study of How Swedish Municipalities Can Market their CSR-Activities

Background: In an increasingly globalised world, municipalities more than ever have to compete with each other. Thus, the need to create a brand image has become vital for municipalities. Place branding is the tool that has enabled municipalities to create a brand image in order to attract stakeholders such as potential visitors, residents and businesses. The sustainability phenomenon Corporate Social Responsibility (CSR) has recently become an attractive factor within place branding. Although, the concept of CSR is most commonly implemented within the private sector, CSR initiatives within the public sector are recognised as an integral part. Therefore, the issue of how municipalities can market and communicate their CSR-actives has arisen.  Purpose: The aim of this research is to explore how Swedish municipalities can market their CSR-activities, in order to gain competitive advantages as attractive cities. In further details, this research focuses on how municipalities can use place branding to market their CSR-activities and how they can communicate this to current and potential stakeholders. Method: In order to fulfil this purpose, an interpretivist methodology was adopted with an abductive approach. In regard to this, an exploratory design was developed. More specifically, it was conducted with a mixed method, using a quantitative content analysis and qualitative indepth interviews with knowledgeable experts within CSR from the most relevant departments in the municipalities. Conclusion: The findings indicate that the use of place branding can help municipalities with a sustainable profile to gain competitive advantages. Furthermore, it became apparent that the use of place branding strategies, such as slogan, logotypes, events and cooperation with stakeholders, could enhance the brand image of municipalities and enable them to attract potential stakeholders. In regards to the communication channels, the findings suggest municipalities to communicate their CSR-activities through websites, social media, press conferences, seminars and events.

O descompasso de uma experiência: avaliação do Programa Habitar Brasil na Comunidade África-Natal/RN

This research deals with the evaluation of the Programa do Governo Federal para Urbanização de Favelas Habitar Brasil(1993) carried out in the Africa slum - Redinha neighbourhood in Natal-Rn. This study carried out in period from 2005 to 2006 searches to identify the effects of the actions proposed by Program in 1993-1994 about the current urbanistic configuration of the Africa community. It analyzes the effectiveness in the process of achievement of the considered objectives to habitation, communitity equipments, infrastructure and agrarian regularization. On the evaluation process, it has been as reference the works developed by Adauto Cardoso (2004), Blaine Worthen (2004), Ronaldo Garcia (2001) and Rosângela Paz (2006). About the Habitational Policy with approach to the Urbanistic Right and the right to the housing, the reflections by Raquel Rolnik, Nabil Bonduki, Ermínia Maricato, Saule Júnior, Betânia de Moraes Alfonsin and Edésio Fernandes are main references. To gauge the execution of the objectives proposed by Habitar Brasil in 1993, it has searched in the documentary data of the time and in information gotten in interviews with technicians that had participated of the program, consistent references on what was considered, what was executed and the process of the intervention of Habitar Brasil in the Africa community. The area analysis in 2005-2006 has developed on the base of the urbanistic survey of the current situation from the four performance lines of the Program: habitation, infrastructure, community equipments and agrarian regularization, with a current urbanistic evaluation of Africa considering the intervention carried out in 1993 and 1994. The study points out the context of Brazilian Habitational Policy where the Programa Habitar Brasil was launched, explaining the main principles of the Program. In terms of local, it empahsizes the administrative-political factors that had contributed so that Natal-Rn city has been pioneering in the resources captation of Habitar Brazil (1993). Considering Habitar Brazil in Africa, the work argues and presents the intervention diagnosis and the proposal, developed by Program in 1993 evidencing the local problem of the time. After that, it makes a current reading of the area, identifying in 2006 representative elements of Habitar Brasil (1993-1994) for the Africa community. It identifies significant advances in the constitution of the institucional apparatus of the plaining system of Habitation of Social Interest for the city of Natal and points the fragilities in the implementation of the urban infrastructure actions and above all in the achievement of the objectives of the agrarian regularization
