Pierre Duhem’s epistemic aims and the intellectual virtue of humility: a reply to Ivanova

David Stump (2007) has recently argued that Pierre Duhem can be interpreted as a virtue epistemologist. Stump’s claims have been challenged by Milena Ivanova (2010) on the grounds that Duhem’s ‘epistemic aims’ are more modest than those of virtue epistemologists. I challenge Ivanova’s criticism of Stump by arguing that she not distinguish between ‘reliabilist’ and ‘responsibilist’ virtue epistemologies. Once this distinction is drawn, Duhem clearly emerges as a ‘virtue-responsibilist’ in a way that complements Ivanova’s positive proposal that Duhem’s ‘good sense’ reflects a conception of the ‘ideal scientist’. I support my proposal that Duhem is a ‘virtue-responsibilist’ by arguing that his rejection of the possibility of our producing a ‘perfect theory’ reflects the key responsibilist virtue of ‘intellectual humility’.     

‘Good Sense’ in context: A response to Kidd

In his response to my (2010), Ian Kidd claims that my argument against Stump’s interpretation of Duhem’s concept of ‘good sense’ is unsound because it ignores an important distinction within virtue epistemology. In light of the distinction between reliabilist and responsibilist virtue epistemology, Kidd argues that Duhem can be seen as supporting the latter, which he further illustrates with a discussion of Duhem’s argument against ‘perfect theory’. I argue that no substantive argument is offered to show that the distinction is relevant and can establish that Duhem’s ‘good sense’ can be understood within responsibilist virtue epistemology. I furthermore demonstrate that Kidd’s attempt to support his contention relies on a crucial misreading of Duhem’s general philosophy of science, and in doing so highlight the importance of understanding ‘good sense’ in its original context, that of theory choice.     

Retinex理论在航空影像增强中的应用

在航空影像的成像过程中,由于大气衰减、云层、烟雾、向阳、背阳等影响,使获取的影像质量下降,出现对比度降低、亮度不均、色彩失真等问题。针对这些问题,提出结合人眼颜色恒常性的典型计算理论Retinex理论,来模拟人眼视觉的感知模型,通过一个像素和其周围像素的明亮度比较运算,获得对象表面的反射率影像,并基于"灰度世界"假设,对图像进行了后处理。给出了Retinex算法在航空影像增强中的具体实现流程,并进行了计算机仿真实验。结合方差、平均梯度、清晰度等参数,验证了算法在图像对比度、细节增强和色彩保真等方面的效果。

基于动态种群结构的粒子群算法及仿真研究

针对标准粒子群算法易陷入局部最优而早熟的问题,提出了一种基于动态种群结构的粒子群算法。该算法在种群结构中引入小世界网络模型,由于网络模型的演化,使算法具有动态的种群结构,从而保持了种群的多样性。同时为了使粒子尽可能地分布在不同的搜索空间,在网络模型演化过程中考虑了结点的个体价值。为了加快算法的收敛速度,在进化后期采用全局模型粒子群算法。通过对三个经典测试函数优化问题的数值仿真并与其它方法进行比较,结果表明了算法的有效性和实用性。     

Creating ‘Rhizomatic Systems’ for Understanding Complexity in Organizations

The article describes and demonstrates the use of a new research proposal for understanding the complexity in organizations in terms of a Deleuzian sense of an event. It creates the rhizome metaphor that allows the emergence of different ways of systems thinking, a legitimate challenge to the Modernist’s orthodoxy. For Deleuze and Guattari, micropolitics are the essence of what we call ‘rhizomatic systems.’ It is this concept of the organization, as a rhizome or rhizomatic systems that we want to focus from ‘problem solving’ in a real-world situation to the process of problematization, that is, the making or appreciating a series of events in the problematizing fields. The paper draws on the research experience in which participatory action research was carried out in a Korean distribution company. The participatory learning process happened to create a series of events in which ‘time-related research’ was conducted in order to facilitate the process of problematization within the organization.
