全面提高成人高校学报质量的思考

针对全国报刊治理整顿后多数学报由内部发行转为正式学报类期刊的新情况,本文从学报业务工作的几个方面对全面提高成人高校学报(以下简称“成高学报”)办刊质量进行了较详细的论述,旨在对成高学报的办刊工作起到一些促进作用。     

Women and biodiversity: The long journey from users to policy-makers

Although there has been a broad acknowledgment that women's local and traditional knowledge is fundamental to guarantee food security and conserve biological diversity, few women are represented at the managerial and decision‐making level of environmental movements and organizations. The United Nations, its agencies and agreements have long promoted the full and effective participation of women in decision‐making processes. So how can commitments contained in international agreements be translated into concrete actions? By using the case of the Convention on Biological Diversity, one of the key agreements adopted at the 1992 Earth Summit in Rio de Janeiro, this article analyses how gender‐equitable initiatives tend to assume an ad hoc character with few governments effectively involving women in their sustainable development strategies. The views expressed in this article are those of the authors and do not necessarily reflect the official position of the United Nations or its subsidiary bodies.

Safe use of refrigerants for process applications

This paper examines safety issues, with emphasis on central refrigeration plant for process applications. Plantroom hazards including refrigerant leakage, excess pressure, fire and noise are covered. It is concluded that routine surveys which are being conducted in connection with the chlorofluorocarbon and hydrochlorofluorocarbon phase-outs present an opportunity for examining safety issues.     

Information technology — a challenge for the sparsely populated areas

The computer and telecommunications technology has created new opportunities for developing interaction between offices and enterprises located far away from each other. Even if the market forces favour concentration to R & D centres in the big cities and in university towns, there are expectations that the distance over‐bridging qualities of the new technology can create development opportunities for sparsely populated peripheral areas. In this paper the interplay between the new technology and other important factors in the local and regional environment are discussed with the focus on both opportunities and restrictions.     

On the moral acceptability of killing animals

According to a rights view it is acceptable to kill animals if they are innocent threats or shields or are in a lifeboat situation. However, according to advocates of such a view, our practices of killing animals for food or scientific research may be morally unacceptable. In this paper we argue that, even if we grant the basic assumptions of a rights view, a good deal of killing of animals for food and scientific research continues to be morally acceptable.     

Ethical Considerations of the Human–Animal-Relationship Under Conditions of Asymmetry and Ambivalence

Ethical reflection deals not only with the moral standing and handling of animals, it should also include a critical analysis of the underlying relationship. Anthropological, psychological, and sociological aspects of the human–animal-relationship should be taken into account. Two conditions, asymmetry and ambivalence, are taken as the historical and empirical basis for reflections on the human–animal-relationship in late modern societies. These conditions explain the variety of moral practice, apart from paradoxes, and provide a framework to systematize animal ethical problems in a broader field. This allows the development of ideal relationships as moral orientation across anthropocentric or sentientistic ethical theories. These ideal relationships are called the patronage-model, the friendship-model and the partnership-model. The ethical problem of creating transgenic animals is discussed in the light of these ideal relationships.     

Air Pollution Effects on Forest Trees in Balikesir,Turkey

Air pollution has become an actual problem in Balikesir because of rapid urbanisation and increasing of the polluting sources. Air pollutionproblems occur under the unfavorable meteorological conditions which increase in frequency of occurrence in winter due to use of low quality lignite coals for heating. The `Protection of Air Quality' in Turkey dated 1986 is based on the human health criteria. But the critical limit values are lethal for the forest trees as far as SO₂ is concerned. The field observations showed that leaves of the trees have yellow spots indicating acid burns in Balikesir. This study aims at determining the relationships between the SO₂ concentrationsin the air under selected climatic conditions, and the effects of air pollution on forest trees in Balikesir. Samples of leaves were collected from the City Parks in Balikesir, Deirmenboaz forested area located 10 km far fromBalikesiron the Balikesir-Bursa highway, and from the forestation areas near the Balikesir-Edremit highway. Sulfur contents of the leaves were very high especially in the city (2650–5300 g m^-3).Samples from other areas had values lower than this range but above the usual values (850–3612 g m^-3). The diameter increments of the trees were found to be lower and these results clearly showed the adverse impacts. Negative correlations were found between these sulfur concentrations and the daily mean temperatures and wind speeds. Positive correlation was seen between these concentrations and pressures, humidities. Emission sources must be controlled in order to safeguard the forests which protects the soil, facilitate water production, assimilate carbon dioxide in air and produce oxygen. It must be considered that the problems are not only regional but have a global identity.
