对1995年世界景观生态学大会和景观生态学发展的国内外现状进行了思考。当今景观生态学与国际生态学的研究热点(全球变化、生物多样性和持续发展)基本一致,但又有自己的特色,其重点领域包括:①生态空间理论与景观异质性研究;②景观变化模型与未来景观规划;③景观系统分析与GIS应用等。由于经济发展和社会生态意识的不同,使得该学科在各地区间的发展很不平衡。着重就我国的本领域研究状况与国际水平作了比较

It is more and more acknowledged that land-use/cover dynamic change has become a key subject urgently to be dealt with in the study of global environmental change. Supported by the Landsat TM digital images, spatial patterns and temporal variation of land-use change during 1995 -2000 are studied in the paper. According to the land-use dynamic degree model, supported by the 1km GRID data of land-use change and the comprehensive characters of physical, economic and social features, a dynamic regionalization of land-use change is designed to disclose the spatial pattern of land-use change processes. Generally speaking, in the traditional agricultural zones, e.g., Huang-Huai-Hai Plains, Yangtze River Delta and Sichuan Basin, the built-up and residential areas occupy a great proportion of arable land, and in the interlock area of farming and pasturing of northern China and the oases agricultural zones, the reclamation I of arable land is conspicuously driven by changes of production conditions, economic benefits and climatic conditions. The implementation of "returning arable land into woodland or grassland" policies has won initial success in some areas, but it is too early to say that the trend of deforestation has been effectively reversed across China. In this paper, the division of dynamic regionalization of land-use change is designed, for the sake of revealing the temporal and spatial features of land-use change and laying the foundation for the study of regional scale land-use changes. Moreover, an integrated study, including studies of spatial pattern and temporal process of land-use change, is carried out in this paper, which is an interesting try on the comparative studies of spatial pattern on change process and the change process of spatial pattern of land-use change.

En este trabajo se analizan los efectos de una disminución de los tipos de las cotizaciones sociales, compensada con un incremento en los tipos del impuesto sobre el valor añadido, como la que tuvo lugar en España en 1995. Para ello se utiliza un modelo de equilibrio general aplicado a la economía española, que se presenta en dos versiones: una donde los sectores productivos se modelizan en competencia perfecta, y otra donde los mismos sectores se modelizan como oligopolistas a la Cournot, lo cual nos permite analizar la influencia del supuesto de competencia imperfecta sobre los resultados. Se ha realizado asimismo una simulación adicional aplicando un supuesto de equal yield por el que el déficit público y el nivel de bienestar del sector público se mantienen constantes tras la aplicación de la nueva política, con objeto de aislar los efectos secundarios que se podrían derivar de un cambio en el comportamiento del sector público.

This is a dissertation about identity and governance, and how they are mutually constituted. Between 1838 and 1917, the British brought approximately half a million East Indian laborers to the Atlantic to work on sugar plantations. The dissertation argues that contrary to previous historiographical assumptions, indentured East Indians were an amorphous mass of people drawn from various regions of British India. They were brought together not by their innate "Indian-ness" upon their arrival in the Caribbean, but by the common experience of indenture recruitment, transportation and plantation life. Ideas of innate "Indian-ness" were products of an imperial discourse that emerged from and shaped official approaches to governing East Indians in the Atlantic. Government officials and planters promoted visions of East Indians as "primitive" subjects who engaged in child marriage and wife murder. Officials mobilized ideas about gender to sustain racialized stereotypes of East Indian subjects. East Indian women were thought to be promiscuous, and East Indian men were violent and depraved (especially in response to East Indian women's promiscuity). By pointing to these stereotypes about East Indians, government officials and planters could highlight the promise of indenture as a civilizing mechanism. This dissertation links the study of governance and subject formation to complicate ideas of colonial rule as static. It uncovers how colonial processes evolved to handle the challenges posed by migrant populations.
The primary architects of indenture, Caribbean governments, the British Colonial Office, and planters hoped that East Indian indentured laborers would form a stable and easily-governed labor force. They anticipated that the presence of these laborers would undermine the demands of Afro-Creole workers for higher wages and shorter working hours. Indenture, however, was controversial among British liberals who saw it as potentially hindering the creation of a free labor market, and abolitionists who also feared that indenture was a new form of slavery. Using court records, newspapers, legislative documents, bureaucratic correspondence, memoirs, novels, and travel accounts from archives and libraries in Britain, Guyana, and Trinidad and Tobago, this dissertation explores how indenture was envisioned and constantly re-envisioned in response to its critics. It chronicles how the struggles between the planter class and the colonial state for authority over indentured laborers affected the way that indenture functioned in the British Atlantic. In addition to focusing on indenture's official origins, this dissertation examines the actions of East Indian indentured subjects as they are recorded in the imperial archive to explore how these people experienced indenture.
Indenture contracts were central to the justification of indenture and to the creation of a pliable labor force in the Atlantic. According to English common law, only free parties could enter into contracts. Indenture contracts limited the period of indenture and affirmed that laborers would be remunerated for their labor. While the architects of indenture pointed to contracts as evidence that indenture was not slavery, contracts in reality prevented laborers from participating in the free labor market and kept the wages of indentured laborers low. Further, in late nineteenth-century Britain, contracts were civil matters. In the British Atlantic, indentured laborers who violated the terms of their contracts faced criminal trials and their associated punishments such as imprisonment and hard labor. Officials used indenture contracts to exploit the labor and limit the mobility of indentured laborers in a manner that was reminiscent of slavery but that instead established indentured laborers as subjects with limited rights. The dissertation chronicles how indenture contracts spawned a complex inter-imperial bureaucracy in British India, Britain, and the Caribbean that was responsible for the transportation and governance of East Indian indentured laborers overseas.

A lo largo de esta lección hemos presentado una variedad de consideraciones interconectadas, cuyo objeto común ha sido la relación del número natural con los modos de pensamiento y de actuaciones prácticas de mujeres y hombres. Nuestra reflexión se ha centrado en tres elementos fundamentales:Unos instrumentos conceptuales: sistema de los números naturales, simbólicamente estructurado; su evolución histórica y su análisis conceptual.Los modos de uso de este sistema simbólico: funciones cognitivas, así como los estudios que se han propuesto delimitar y caracterizar tales funciones como parte del pensamiento humano, su evolución y las condiciones para su aprendizaje.Los campos de actuación: fenómenos, cuestiones y problemas, en los que se pone en práctica y se trabaja con este sistema; especial importancia hemos concedido a la reflexión crítica en relación con el período escolar.
