Unstable Etching Of Si(110) With Potassium Hydroxide
No full textWe present the experimental data for the morphological evolution of Si(110) etched with Potassium Hydroxide. The observed results are interpreted using a continuum equation. The results reveal the presence of unstable etching, which leads to the formation of a columnar structure on the surface. The early stage of the formation of this columnar structure can be explained by a linear theory. This instability is caused by anisotropic surface tension
Pegada hídrica da produção de cana-de-açúcar no Paraná de 2010 a 2020.
No full textO objetivo deste trabalho foi estimar as pegadas hídricas verde, azul e cinza da cana-de-açúcar, nas principais mesorregiões produtoras do Paraná, de 2010 a 2020. A metodologia utilizada foi proposta por Hoekstra et al. (2011), com adaptações necessárias para a realidade local. A mesorregião Noroeste Paranaense exibiu os maiores valores para a pegada verde (179,05 m³ Mg-1, em 2010, e 200,26 m³ Mg-1, em 2020). Norte Central e Noroeste Paranaense foram as mesorregiões com os maiores valores médios de pegada azul (47,43 m³ Mg-1 e 46,66 m³ Mg-1, respectivamente). O Noroeste Paranaense apresentou também a maior pegada hídrica cinza, com 12,33 m³ Mg-1, em 2010, e 13,79 m³ Mg-1, em 2020. A mesorregião de maior pegada hídrica média no período foi o Noroeste Paranaense, com 249,3 m³ Mg-1, e a menor pegada média foi a do Norte Pioneiro Paranaense, com 179,35 m³ Mg-1. A média da pegada hídrica total da produção de cana-de-açúcar das mesorregiões paranaenses foi de 206,63 m³ Mg-1
Efeitos da desregulamentação econômica da década de 1990 sobre a agroindústria canavieira brasileira
No full textTCC (Graduação) - Universidade Federal de Santa Catarina. Centro Socioeconômico. Curso de Graduação em Ciências Econômicas.A importância da agroindústria da cana-de-açúcar na formação do padrão de civilização vigente no Brasil é inegável e, como se verá, ela tem atravessado séculos com a mesma configuração básica, tendo sido derrotados todas as tentativas de mudança de sua característica histórica. Em outros termos, a agroindústria canavieira nasceu de forma integrada verticalmente, ou seja, concentrada, e tem conseguido manter-se assim até os dias atuais. Para isso foi fundamental a estreita vinculação com o componente político até final da década de 1980, onde o Estado atuou de forma a manter intacta esse componente estrutural do complexo.A partir de 1990, ocorre o afastamento do Estado perante essa agroindústria, a qual passa por um processo de desregulamentação. Este trabalho vem com o objetivo de analisar os efeitos dessa desregulamentação perante a agroindústria da cana. Para isso este trabalho utilizará o método histórico, ao qual demonstrará todo o surgimento desse complexo, sua evolução e sua forma de interação antes e depois do afastamento do Estado, atingindo assim o objetivo proposto por esse estudo.The importance of agribusiness cane sugar in shaping the pattern of civilization is undeniable force in Brazil and, as we shall see, she has crossed centuries with the same basic configuration, having been defeated all attempts to change its historical characteristic. In other words, this complex of activities was born so vertically integrated, in other words, concentrated and has managed to remain so to this day. For it was essential to close ties with the political component by the end of the 1980s, where the State acted to keep intact this structural component of the complex. Since 1990, there is a departure from the State before this agribusiness, which goes through a process of deregulation. This work is aimed at analyzing the effects of deregulation before the sugarcane industry. For this work that uses the historical method, which all show the emergence of this complex, its evolution and its form of interaction before and after the removal of the state, thereby achieving the goal proposed for this study
Trade dynamics in the Italian floriculture sector within EU borders: A gravity model analysis
No full textDespite its economic magnitude worldwide, the scientific attention to the floriculture sector remains scarce
within the borders of the European Union. Focusing on Italy, the aim of this paper is to provide an insight
into the floriculture trade for the first time. More specifically, in addition to describing trade dynamics
of the floriculture sector both in Italy and in the European Union in recent years, this paper applies a gravity
model to investigate and evaluate the role of some major economic and geographical variables as determinants
of Italian trade flows of cut flowers and live plants within the European Union, from 2001 to 2013.
Among these, findings prove that the most important are the GDP per capita of the European trade partners,
as well as their production and consumption volumes
観光地域づくりによる地域再生の評価に関する研究 : ドミニカ共和国プエルトプラタ県の事例
No full textCommunity development through tourism has attracted much attention from both practitioners and scholars. Tourism is believed to be able to rejuvenate deteriorating local communities through positive economic effects; particularly, it has the potential to revitalize local economies. However, tourism alone cannot improve communities because many issues hamper the management of community development and evaluation of its sustainability. This study examines the strategic planning of community development through tourism in Puerto Plata, the Dominican Republic, where an international cooperation project by the Japanese International Cooperation Agency was started in November 2009. We use a tentative evaluation methodology based on the nature of balance sheet to determine the potential of communities and outcomes of the development
観光地域における非営利・営利組織のガバナンスと協働モデルにかんする研究 : 北海道弟子屈町の事例分析から
No full textThis paper discusses the destination governance formed by diverse players in tourism destinations. The case in Teshikaga-cho in Hokkaido was studied as it relates to the collaboration of non-profit and profit organizations. The author interviewed the key actors and reviewed the related documents. The results of this study indicate that the formation of destination governance was mainly initiated and led by non-profit organizations. Furthermore, a collaborative relationship was observed between non-profit and profit organizations, which is described by the simple relationship model. This is likely to be an excellent case for the formation of destination governance and the development of sustainable tourism for tourism destinations
地域沿岸域管理の提案 : 沿岸域における利用者の価値実現
No full textThe coastal zone is a complex natural system consisting of a marine and a terrestrial environment. It is used excessively by a variety of coastal users because of its important resources and its unique environment. Thus, the need for successful coastal zone management arises. However, there is no best solution for users involved in the coastal zone because the goals of coastal zone management vary for all users and the authorities concerned. A large number of attempts have been carried out in many coastal states to build optimal coastal zone management. Nevertheless, little attention has been given to why and how a successful coastal zone management has developed in a particular region or district. Therefore, this study attempts to analyze the development of regional coastal zone management system based on several case studies carried out in Japan. Several development stages are observed and their characteristics are described. The author also proposes "a circuit model" that explains transformational changes in management system by focusing on knowledge creation. The model can provide a useful evolutionary design for adaptive management by introducing, transforming and creating knowledge autonomously. The author believes that the model can be a unique and useful tool for designing a local coastal zone management system
地域再生におけるよそ者の分類と変容に関する研究 ―資源所有と商品・サービス創出による分類モデルの提案―
No full textOver the past decade, community leaders and municipal authorities in Japan have viewed community development as a crucial measure to improve the local economy, enhance community activity, create employment, and increase social capital. It is also widely recognized that community development to require supports especially from an external party. Thus, in this paper, the concept of outsiders or external parties discussed in previous community development studies is reviewed. The author proposed four quadrants model explaining diversities of outsiders. The findings revealed that outsiders to the community including recent proposed “related population” can be classified into four segments by balance of produce and consumption and ownership of local resources. Finally, this study can contribute to the formation of community policy and the development of day-to-day local community management
旅行費用法を用いた舳倉島のバードウォッチングの経済的価値の推定
No full textHegurajima is located at 50km north of Noto peninsular in the middle of Japan. The island is famous for its unique feature as the best place for bird watching in Japan and receives more than 800 bird watchers in 1994. However, only few attempts have so far been made to estimate the economic value of bird watching. The author intends to evaluate the consumer surplus generated by the bird watchers. The consumer surplus of the bird watching is obtained using the travel cost method. The result shows that the consumer surplus of the bird watching at the island is about 14.43 million yen per year. This could be an useful indication for the cost allocation of environmental conservation and future management for visitors to the island
地域づくりにおける専門家にかんする研究 : 「ゆるやかな専門性」と「有限責任の専門家」の提案
No full textCommunity development movements, which emerged in Japan in the 1980, are believed to have contributed to regional rejuvenation through the restructuring of communities as well as through economic development. The movements originally developed under administrative leadership, however the nature of regional development has changed drastically due to the decentralization of Japan's political system and socio-economic changes in Japan's rural society. Changes were further accelerated by the rise of nonprofit activities in the late 1990s. This article tries to analyze the types of experts involved in these movements. Three typical types of experts are found in community development, and their development stages are described. To prevent over-involvement by such experts, the author proposes the idea of flexible expertise and limited liability experts based on an intensive review of literature and an analysis of cases
