Interdisciplinarity: Potentials and Challenges

Interdisciplinarity, as a concept and practice, is reviewed and related to a recent article (Romm, 1998) in this journal. Authors advocating interdisciplinarity for social research and problem solving seem to have diverse, if often largely implicit, epistemological, and other assumptions informing their proposals. Romm (1998) develops and advocates a critical and reflexive orientation for tying interdisciplinarity to action research and related endeavors. For some academicians, however, interdisciplinarity appears to be considered a relatively unproblematic pursuit of merely selecting appropriate methods. Significant issues and questions concerning interdisciplinary pursuits, particularly in academic settings, exist and are briefly explored, based on the experiences and perceptions of the author. Basic structures and processes found in fields such as action research/science and management systems often seem neglected and very much needed for interdisciplinary inquiry and knowledge construction.     

光纤暗孤子的相互作用

利用最小作用量原理，从非线性Ｓｃｈｒｄｉｎｇｅｒ方程，导出两个暗孤子之间的相互作用．它作为孤子间距△和初位相差θ的函数，随△的增大而指数地减小，当两个孤子之间初位相差θ＜π／２时相互排斥，θ＝π／２时几乎不存在相互作用

陕西克山病的构造环境机理初探

通过对前人克山病研究成果的分析，说明克山病的病因尚无定论，指出前人对克山病的归属和致病机制及影响因子等存在许多疑团。在此基础上，以陕西病区为研究对象，提出应从地质构造角度探讨构造环境和克山病的内在联系，从构造背景、采样化验、因子相关性分析出发，并结合地球重力和磁力场异常测试以及地球化学同位素实验对照分析，构建出陕西克山病和构造环境的耦合关系模式，为克山病的根治指明未来研究方向。

Dealing with coercion: Critical Systems Heuristics and beyond

This paper begins with an introduction to the philosophy and methodology of Critical Systems Heuristics (CSH). Following this, various citicisms of CSH are reviewed. One particularly important criticism is that CSH should not be seen as a replacement for other systems approaches, but as complementary to them. It is this idea of complementarity that has led several Critical Systems thinkers to take CSH, along with a number of other systems methods, and try to show that they are most appropriately used in different contexts. CSH, it is said, is at its most useful when we are confronted with coercive situations. However, in this paper it is argued that coercion is usually characterised by closure of debate. Therefore CSH, which depends upon the possibility of communication (or arbitration) between stakeholder groups, becomes redundant when coercion is experienced. It is further argued that coercion can only be addressed adequately by widening our definition of systems practice to include campaigning and direct political action. There is still considerable scope for developing these areas in the systems domain.
