Methodological foundations of systems methodologies

In social systems science generally, and in management science particularly, recent developments in the variety of types of specific problem-solving methodologies (under the rubric of hard and soft systems approaches) have given an impetus to a line of inquiry, as well as debate on the nature of those methodologies. On the one hand, there has been the view that what we are witnessing is a form of Kuhnian crisis. On the other hand, a complementarist view of developments has been argued and a contingency approach proposed. But one thing has been common among the competing views: a belief that the prospects for further advances in the design and application of those methodologies, and in resolving the current controversies, lie in serious attempts to reconsider and clarify the underlying metatheoretical assumptions and concerns. This paper is an attempt to contribute to such an endeavor. A brief exposition of three methodological foundations (namely, empiricism, hermeneutics, and critique) is made, not only with the purpose of highlighting the nature as well as the limits of their epistemological and ethical claims, but also as a basis for illuminating both the nature of contemporary work on systems inquiry, design, and problem solving and the ongoing debate on what constitutes appropriate criteria for choice of specific methodologies.     

Misuses of biology in the context of the paranormal

Summary Public suspicion of science stems from science's challenging of perceptions and myths about reality, and a public fear of new technology. The result is a susceptibility to pseudoscience. In claiming that creation science is as valid as evolution the creationists misquote scientists and seek to spread their own scientific myths concerning a young age for the earth, an act of creation based on a particular literalist interpretation of the Christian Bible and a single worldwide flood. They use methods of debate and politics, rather than scientific research. A selection of their arguments is examined and the nature of the evidence for evolution is discussed. Problems with the creation science model are noted. In the myth of the hundredth monkey phenomenon, original research is misquoted to denigrate scientific research and support sentimental ideas of paranormal events. The misuse of science is seen as damaging to society because it reduces the effective gathering and application of scientific information. However, pseudoscience provides a valuable guide to gaps in public scientific education.

冷水鱼固着类纤毛虫PCR检测方法探讨及感染因素分析

针对冷水鱼养殖中固着类纤毛虫检测难和污染源不明确、种类鉴定难的问题,对冷水鱼养殖环境中固着类纤毛虫的主要寄生种类及感染因素进行调查分析,在不同季节于河北省内采集冷水鱼和水环境样本。首先,采用形态学方法对鱼体及水环境中的固着类纤毛虫进行初步鉴定;然后,建立PCR方法进行分子水平鉴定,并进行系统发育学分析;最后,对冷水鱼感染寄生虫的原因进行分析。形态学鉴定结果表明,冷水鱼寄生的固着类纤毛虫主要有累枝虫(Epistylis sp.)和钟虫(Vorticella sp.)2类;引物设计、敏感性和特异性试验结果显示,建立的寄生虫PCR检测方法有效,测序比对和系统发育分析结果进一步验证了其形态学结果;运用已建立的PCR方法检测出固着类纤毛虫在水环境中高达94.38%,鱼体广泛寄生,感染率达到了100%;且无季节差异,水体中的虫体可能是造成鱼长期感染的原因之一。研究数据可为冷水鱼病害的科学预测、预防和治疗提供依据,同时为冷水鱼养殖产业的可持续发展提供疫病防治参考。
