Landscape metrics are offered and designed to be as versatile as possible using several programs. In this paper it is attempted to （a） collect all the metrics found in the literature, （b） classify them, and （c） evaluate them through their use. An extensive investigation of the literature has been performed. Small discussion of each metric is provided to its concept, definition, use, way of calculation and in some cases contribution to the sustainable development. The frequency of used papers per each index has been taken into account. The most used to the least used six metrics have the following order： Area/Density/Edge; Isolation Proximity; Diversity; Contagion Interspersion; Shape; Connectivity. Moreover, the frequency of used papers is divided into five groups, i.e. group A till group E. Concluding, it has been provided an explanation of the results regarding to the four indices of group A and two indices from the group B.展开更多

From the study of Games theory, this article tries to find out a way to adjust the rules of the game, to refine the science research environment, improve the quality of research paper, and then realize the sustainable development of Chinese universities.展开更多

The rapid growth of the elderly population will inevitably bring about changes in the family structures, which leads to the inevitable development trend of the old-age pension institutions for the elderly. With the progress of the society, the needs of the elderly for the old-age pension are not only satisfied with their life care, but also with the spiritual needs. Based on the planning contents of the 13th Five-Year Plan for the elderly, on the basis of the Maslow＇s demand level theory, this paper analyzes the present status of the services of the institutions for the elderly to the elderly psychological health, and concludes that the needs of the emotions of the elderly, the needs of their self-esteem, the needs of their self-realization and their physiological needs of the elderly and their security needs are equally important.展开更多

The data came from three sources： her essays, reflective journals, and my semi-structured interviews with her. Major findings can be summed up as follows： 1） at the initial stage, the participant was weak in rational thinking; 2） as she had more writing practice, she made progress in ideas and organization of ideas but not in expression of ideas; and 3） factors facilitating or constraining her development primarily include language input, cultural identification, teacher feedback and motivation.展开更多
