On False Discovery and Non‐discovery Proportions of the Dynamic Adaptive Procedure

This paper studies the asymptotic behaviour of the false discovery and non‐discovery proportions of the dynamic adaptive procedure under some dependence structure. A Bahadur‐type representation of the cut point in simultaneously performing a large scale of tests is presented. The asymptotic bias decompositions of the false discovery and non‐discovery proportions are given under some dependence structure. In addition to existing literatures, we find that the randomness due to the dynamic selection of the tuning parameter in estimating the true null rate serves as a source of the approximation error in the Bahadur representation and enters into the asymptotic bias term of the false discovery proportion and those of the false non‐discovery proportion. The theory explains to some extent why some seemingly attractive dynamic adaptive procedures do not outperform the competing fixed adaptive procedures substantially in some situations. Simulations justify our theory and findings.

The “diseased” activist's body as the site of trauma: Anti-racist struggles and the postrace academy

This paper is an autoethnographic account of the “racialized activist body” in the White academy and in tandem the bio-politics and bio-ethics of its right to be an affective body or to possess its senses against the trauma of anti-racist struggles in higher education institutions. The paper argues that in the postrace university, the “activist body” birthed through trauma becomes a conduit for the pain of others enacting it as a site for the deposition and transmutation of trauma in the quest for racial and social justice. It employs Bracha Ettinger’s notion of “matrixial borderspace” to examine the interplay of social relations between of the activist body and other traumatized subjects in the provision of care as an activist. Two narratives unfold in the paper fusing the articulations of the main text with the paratext to unleash the tumultuous psyche of the activist and her journey of voicing resistance in her anti-racist struggles. In the process, the activist body emerges as a “diseased site,” overloaded with the trauma of others, yet numbed in its inability to reconnect with its own corporeality and professional identity in its interface with White governmentality. The paper asserts that anti-racist struggles reassemble the activist body, tightly welding it with exhaustion which manifests in the pervasiveness of racial battle fatigue in the ivory tower.

2000m~3二甲醚球罐的在线检测及有限元分析

首先,使用多通道声发射检测仪PAC SAMOS-48检测在用2000m3二甲醚球形储罐,判定出该设备存在表面裂纹缺陷及其所处位置。然后,采用超声波检测方法,确定了裂纹形状和大小。用Newman—Raju方法研究了表征裂纹缺陷前沿应力场以及位移场的重要参量即应力强度因子,并利用ANSYS建立简化的有限元模型,最终得到裂纹的应力云图和该裂纹前沿应力强度因子值,与工程估算方法得到的数值进行对比,结果表明有限元方法应用于压力容器缺陷的分析是适用的。     

The geographic distribution of gaming machine proceeds in New Zealand

ABSTRACT

Within NZ gambling and its associated harms are well-researched topics. However, most studies to date have relied upon the use of survey methodology or have focused on individual regions. In this paper we distribute gaming machine proceeds (GMP) from gaming venues to the surrounding localities in order to derive estimates of GMP per capita. It is hoped these estimates will enable the trusts who operate the electronic gaming machines (EGMs), and who are responsible for reinvesting a proportion of proceeds back into the community, to more accurately target funding towards the areas most affected by the harms of EGM gambling. Our estimates of GMP per capita also provide a means of assessing the criterion validity of the recently developed Dynamic Deprivation Index. Furthermore, although it is well known that Māori and Pacific Island populations have a higher incidence of problem gambling, our results imply that when controlling for socio-economic deprivation and the geographic location of EGMs the associations between ethnicity and GMP per capita are weak. From a policy perspective, this suggests the most effective way of limiting the harms of EGM gambling on these populations is to place tighter controls on the number of venues within their communities.     

关于学习本质的哲学探索

学习能力是人类传承文明的重要条件之一,也是人类智能的显著特征.但是关于人类是如何学习和学习的本质是什么,若干年来学者们一直没有定论.文章试图从哲学的视野对这一问题进行探索,通过对认知主义学习论、行为主义学习论以及建构主义学习论进行解读分析,试图得出关于学习本质研究的新进路.同时通过对人类学习本质研究的局限性引出了机器学习这个概念,从哲学角度对两者比较分析之后认为计算机仍是无法完全模拟或实现人类学习的.
