Eco-Africa and facilitated community participation in the /AI-/AIS Richtersveld Transfrontier Conservation Area

Classen Monique, Ann January 2017 (has links)
This research investigates how environmental consultancies frame participation as a tool for project implementation using a cross-border conservation initiative as a case study. The study focuses on the facilitation process led by Eco-Africa Environmental Consultants during the establishment of the /Ai-/Ais Richtersveld Transfrontier Conservation Area. This study analyzes the promise of participation as a crucial component for Transfrontier Conservation Areas. Analyzing participation of the Richtersvelders is necessary for understanding the work that was carried out and how it was experienced by the stakeholders. The study refers to participation in conservancies in community-based resource management, where the role of non-government organizations and environmental consultancies is well established. Primary data were collected through qualitative document analysis, semi-structured interviews with members of the four communities and with Eco-Africa Environmental Consultants. The findings of the study are that there was a strong attempt towards an all-inclusive bottom-up approach to participation. However, such the success of such an approach was hampered by local mismanagement, politics of money, and a marketing strategy favoring the South African National Parks and the Transfrontier Conservation project.

Going green, going clean: Lean-green sustainability strategy and firm growth

Lartey, T., Yirenkyi, D.O., Adomako, Samuel, Danso, A., Amankwah-Amoah, J., Alam, A. 27 May 2019 (has links)
Yes / Despite the widespread recognition of the paybacks of “going green” and “going clean”, limited research has focused on the impact of lean-green strategy on firm growth. In this study, we contribute to strategy and environmental sustainability literatures by investigating the possibility that the influence on lean-green strategy and firm growth is driven by different levels of industry competition, managerial power and family ties. Using panel data from 732 firms in four major industrialised economies (the US, Germany, France and the UK), we found that lean-green strategy positively relates to firm growth and this relationship is amplified at higher levels of competition, managerial power and family ties. Theoretical and practical implications of the study are also discussed.

The Space Debris Environment and Satellite Manufacturing

Tam, Walter 01 January 2015 (has links)
Space debris is a growing threat to operational satellites and satellite manufacturing organizations. Leaders in satellite manufacturing organizations lacking adequate knowledge on the space debris risks could be at a competitive disadvantage. The purpose of this explorative case study was to explore strategies leaders in satellite manufacturing organizations use to mitigate risks through the conceptual lens of stakeholder theory, contingency theory, and general system theory. The research questions addressed strategies to mitigate the debris threat from the perspectives of both ongoing concerns and long-term risk resolution. Data were collected via in-depth interviews with 12 leaders, purposively selected, in satellite manufacturing organizations, and supplemented with documentation from the literature and archival records from NASA. Member checking was used to validate the transcribed data subsequently coded into 6 themes that included: meeting requirements; using analytical techniques; using shielding to protect satellites; implementing material and process innovation; developing satellite services; and generating end of mission requirements. Recommendations include maintaining and developing analytical competencies, funding research and development, and establishing standardization. Using strategies that facilitate risk mitigation and the preservation of the space environment, business leaders could benefit by developing strategic road maps that ensure continued access to space. Implications for social change include contributing to social stability, technology advancement, increased knowledge base, economic growth, higher education, and improved standard of living.

Consumer Acceptance, Barriers and Success Factors of Peer-to-Peer Carsharing in Perspective of Connected Car Services and Autonomous Vehicles

Amann, Volker 01 July 2017 (has links) (PDF)
Until now, car ownership has been a symbol of wealth and personal freedom. The high value of the car in society has been enforced by the powerful automotive industry with their well-funded marketing budgets. Currently, there are one billion cars worldwide, possibly increasing to 2,8 billion by 2050. However, the awareness of the negative consequences of car ownership on the environment, cities, and individuals in terms of reduced personal and financial freedom is increasing. The trend towards collaborative consumption involving activities like sharing and trading is leading to a shift from ownership to the access of goods and services. In this context, carsharing is receiving more and more attention and the number of users for B2C carsharing models is increasing exponentially. The least-developed business model with the biggest opportunities in terms of environmental benefits is peer-to-peer carsharing (P2P carsharing). Providers face daunting problems in reaching critical mass, due to a lack of consumer acceptance. Academic contributions on the topic are rare. The goal of this dissertation is to capture the acceptance factors, barriers and success factors for P2P carsharing. Additionally, the phenomenon is explored within the perspective of disruptive technologies, including the connected car and autonomous vehicles. A comprehensive literature review including collaborative consumption, carsharing, and in particular P2P carsharing, has been conducted. A mixed-method approach has been used. Qualitative interviews with leading academic and industry experts in the field of collaborative consumption and shared mobility, as well as a focus group discussion, have been executed. In the quantitative survey, the identified factors have been integrated into the Technological Acceptance Model (TAM), the theoretical foundation of the work. A representative survey was conducted in Austria with 801 respondents. The results were generated by applying a partial least squares analysis. Results show that the TAM model, including the extensions, appeared to be applicable. In particular, people with an innovative mindset are open to the usage of the business model. The main motivational factors for participating are economic, utility and enjoyment. The personal attachment towards one's own car remains one of the main barriers, next to fear of sharing and loss of convenience. Success factors in increasing acceptance are - among others - trust, value-added services and keyless car exchange. The preferred usage model for autonomous vehicles tends to be ownership. Even though the awareness of P2P carsharing is rather low among the Austrian population, 13,6% state that they would use the service. Sharing one's privately owned autonomous vehicle with others met with even higher levels of approval from the respondents. The extension of the TAM, as well as its application to a new field outside information system (IS) research, can be viewed as the major academic contribution of this work. Practical implications for P2P carsharing providers and the automotive industry include strategic recommendations regarding the current disruptive trends within the automotive industry. In particular, concrete measures have been identified to scale the business model by addressing new customers and reducing the identified barriers by providing extensive knowledge of relevant success factors.

No. of bitstreams: 1 JoaoAAB_DISSERT.pdf: 2621016 bytes, checksum: 39aa654f0df748b1db86062c61ed8f35 (MD5) Previous issue date: 2013-05-16 / Emerald mining is an important area of the economy in Brazil, country which is in second place among the exporting nations of this gem. Due to the process of extraction, a great amount of reject is generated. Since there is no appropriate destination, the reject is abandoned around the mining industries, contributing to environment degradation. Nowadays, some of the most relevant things to an industry in general are: energy conservation, cost reduction, quality and productivity enhancement. The production of isolating, transformed refractory materials achieves the sustainability dimension when protection of the environment is incorporated to such process. This work investigates the use of emerald mining rejects in the ceramic body of refractory materials, aiming at obtaining a product whose characteristics are compatible with commercial products and, at the same time, allow the use of such rejects to solve the environmental issue caused by its disposal in nature. X-ray fluorescence analysis show that the emerald reject obtained after the flotation to extract molybdenum and mica has 70% of silica and alumina (SiO2+Al2O3) and 21% of a basic oxides and alkaline metals and earthy alkaline mixture (Na2O, K2O, CaO e MgO). Because of the significant amount of silica and alumina present in the reject, four refractory ceramic bodies were prepared. Samples with a rectangular shape and dimensions 100x50x10 mm were pressed in a steel mold at 27,5 MPa and sintered at 1200?C for 40 min. under environment atmosphere in a resistive oven. The sintered samples were characterized in relation to the chemical composition (FRX), mineralogical composition (DRX), microstructure (MEV) and physical and mechanical properties. The results indicate that the mixture with 45% of reject, 45% of alumina and 10% of kaolin presents a refractory quality of 1420?C, dimensional linear variation below 2.00%, apparent specific mass of 1,56 g/cm3 and porosity of 46,68%, which demonstrates the potential use of the reject as raw material for the industry of isolating transformed refractory materials / A minera??o de esmeraldas ? uma importante ?rea da atividade econ?mica do Brasil, pa?s que ocupa o segundo lugar entre as na??es exportadoras dessa gema. Em virtude do processo de extra??o, uma grande quantidade de rejeito ? gerada. Como n?o h? uma destina??o apropriada, o rejeito ? abandonado ao redor das mineradoras, contribuindo, assim, para a degrada??o do meio ambiente. Atualmente, alguns dos pontos de maior relev?ncia para a ind?stria em geral s?o: conserva??o de energia, redu??o de custos, melhoria de qualidade e produtividade. A produ??o de refrat?rios conformados isolantes ganha a dimens?o de sustentabilidade quando a prote??o ao meio ambiente ? incorporada a tal processo. Este trabalho investiga o uso de rejeitos da minera??o de esmeraldas na massa cer?mica de materiais refrat?rios, com intuito de obter um produto com caracter?sticas compat?veis aos produtos comerciais e, ao mesmo tempo, viabilizar a utiliza??o de tais rejeitos para solucionar o problema ambiental gerado por seu descarte na natureza. An?lises de fluoresc?ncia de raios x mostram que o rejeito de esmeraldas obtido ap?s a flota??o para retirada de molibd?nio e mica possui 70% de s?lica e alumina (SiO2+Al2O3) e 21% de uma mistura de ?xidos b?sicos de metais alcalinos e alcalinos terrosos (Na2O, K2O, CaO e MgO). Em fun??o dos significativos teores de s?lica e de alumina presentes no rejeito, quatro massas cer?micas refrat?rias foram preparadas. Corpos de prova com forma retangular e dimens?es 100x50x10 mm foram prensados em uma matriz de a?o a 27,5 MPa e sinterizados a 1200?C por 40 min. sob atmosfera ambiente em forno resistivo. Os corpos de prova sinterizados foram caracterizados com rela??o ? composi??o qu?mica (FRX), composi??o mineral?gica (DRX), microestrutura (MEV) e propriedades f?sicas e mec?nicas. Os resultados obtidos indicam que a mistura com 45% de rejeito, 45% de alumina e 10% de caulim apresenta uma refratariedade de 1420?C, varia??o linear dimensional inferior a 2,00%, densidade de massa aparente de 1,56 g/cm3 e porosidade total de 46,68%. Isto demonstra que o rejeito possui um potencial como mat?ria-prima para aplica??o na ind?stria de materiais refrat?rios conformados isolante

AVALIAÃÃO AMBIENTAL: UMA PERCEPÃÃO DOS SERVIDORES DA SECRETARIA DA FAZENDA DO ESTADO DO CEARÃ / ENVIRONMENTAL REVIEW: ONE PERCEPTION OF SERVERS DEPARTMENT OF FINANCE OF THE STATE OF CEARÃ

Yolita de AraÃjo e SÃ 30 August 2012 (has links)
nÃo hà / Este trabalho cientÃfico teve como assunto o meio ambiente. A temÃtica tem sido debatida amplamente por governos e sociedade por envolver questÃes que dizem respeito à vida nÃo apenas do ser humano, mas de todos os seres vivos e a preservaÃÃo dos recursos da natureza. A pesquisa teve por finalidade avaliar o servidor pÃblico lotado na Secretaria da Fazenda do Estado do Cearà a partir de dois pressupostos: percepÃÃes do agente pÃblico em relaÃÃo à Responsabilidade Socioambiental e o papel do Estado frente à questÃo ambiental. Diante da importÃncia de preservaÃÃo dos recursos e bens naturais mediante a mÃquina administrativa, a pesquisa empÃrica buscou conhecer o perfil, o nÃvel de conhecimento, o grau de importÃncia, interesses, expectativas e situaÃÃes vivenciadas pelo servidor no Ãmbito de sua rotina de trabalho e associÃ-los com os aspectos relacionados à percepÃÃo. Para tanto, a metodologia fez uso da tÃcnica de questionÃrios, os quais foram entregues de forma impressa a 149 respondentes, distribuÃdos entre servidores fazendÃrios e prestadores de serviÃos terceirizados: sujeitos da pesquisa. O estudo teve a funÃÃo de descrever as caracterÃsticas sociodemogrÃficas de populaÃÃo especÃfica, utilizando tÃcnica de amostragem dado seu carÃter representativo. A estratÃgia de pesquisa valeu-se de abordagens do tipo quantitativa-descritiva para avaliar opiniÃes e percepÃÃes do agente pÃblico, empregando escalas que permitiram a quantificaÃÃo, tendo em vista a aplicaÃÃo do mÃtodo estatÃstico. A anÃlise bibliogrÃfica incluiu autores que trataram de assuntos multidisciplinares como responsabilidade social, educaÃÃo ambiental e sustentabilidade, alÃm da leitura de documentos institucionais para fundamentar o estudo teÃrico, reforÃando os pressupostos que dÃo sustentaÃÃo ao objeto da pesquisa. Os resultados validaram as duas hipÃteses sobre a percepÃÃo do servidor acerca do meio ambiente. O agente pÃblico se mostra indiferente a essa questÃo por haver baixa consciÃncia ambiental na esfera pÃblica onde està inserido, mas reconhece a existÃncia de problemas ambientais. TambÃm reconhece a necessidade de sua participaÃÃo como sujeito de mudanÃas. Da mesma forma, reconhece um Estado omisso em relaÃÃo a programas socioambientais, ainda que o atribua a responsabilidade pela elaboraÃÃo e execuÃÃo de polÃticas pÃblicas de meio ambiente. Nesse sentido, a percepÃÃo socioambiental do servidor fazendÃrio fica comprometida porque nÃo hà senso de continuidade. Diante dessas consideraÃÃes, foi sugerida a execuÃÃo de programas de educaÃÃo ambiental como forma de estimular e incentivar as melhores prÃticas ambientais na administraÃÃo pÃblica. / This scientific work was to subject the environment. The topic has been widely debated by governments and society by engaging questions that pertain to life not only of human beings but all living beings and the preservation of natural resources. The research aimed to evaluate the public server packed in Finance Department of the State of Cearà from two assumptions: perceptions of the public official in relation to Environmental Responsibility and the role of the state to environmental issues. Given the importance of conservation of natural resources and assets through the administrative machinery, empirical research sought to understand the profile, the level of knowledge, the degree of importance, interests, expectations and situations experienced by the server as part of your work routine and associate them with the aspects related to perception. Therefore, the methodology made use of the technique of questionnaires, which were delivered in print to 149 respondents, distributed across servers Farmers and outsourced service providers: research subjects. The study aimed to describe the function of specific population sociodemographic characteristics, using sampling technique given its representative character. The research strategy took advantage of approaches like quantitative-descriptive to assess opinions and perceptions of the public official, employing scales that allowed the quantification, with a view to applying the statistical method. The literature review included authors who treated multidisciplinary subjects such as social responsibility, environmental education and sustainability, beyond reading of institutional documents to substantiate the theoretical study, reinforcing the assumptions that support the object of the search. The results validate the two hypotheses about the perception about the server environment. The public official is indifferent to this question because there is low environmental awareness in the public sphere where it is inserted, but recognizes the existence of environmental problems. It also recognizes the need for their participation as subject to change. Similarly, a State recognizes silent on social and environmental programs, although the assign responsibility for developing and implementing public policy environment. In this sense, the perception of environmental fazendÃrio server is compromised because there is a sense of continuity. Given these considerations, it was suggested the implementation of environmental education programs as a way to stimulate and encourage environmental best practice in public administration.
