Celebrating Joan Acker: Sociologist,fearless feminist,friend

Joan Acker's life reflects a time when middle‐class women were expected to be satisfied with maintaining the home front, serving husbands and children, not having paid‐work careers. After living “the ideal” for 37 years, Acker took a new path by earning a Ph. D. and producing path‐breaking scholarship that challenged taken‐for‐granted beliefs about gender, family, work, and organizations. Acker spoke “truth to power” and was an academic heroine in posing feminist challenges to injustices involving gender, social class, and race/ethnicity, particularly (but not solely) related to the workplace. This overview lets Joan tell her story and offers reflections on her milestone publications as seen by Pat Martin.     

On the power of goodness-of-fit tests for the exponential distribution under progressive Type-II censoring

The aim of this article is to review existing goodness-of-fit tests for the exponential distribution under progressive Type-II censoring and to provide some new ideas and adjustments. In particular, we consider two-parameter exponentially distributed random variables and adapt the proposed test procedures to our scenario if necessary. Then, we compare their power by an extensive simulation study. Furthermore, we propose five new test procedures that provide reasonable alternatives to those already known.     

Testing the dilation order by using cumulative residual Tsallis entropy

In this paper, we introduce a new test for the dilation order based on cumulative residual Tsallis entropy of order α. The effect of the values of parameter α on the power of the test statistics is numerically investigated. The asymptotic distribution of the test statistic is given. The performance of the test statistic is evaluated using a simulation study. Finally, some numerical examples illustrating the theory are also given.     

A comparison of recent nonparametric methods for testing effects in two-by-two factorial designs

The two-way two-levels crossed factorial design is a commonly used design by practitioners at the exploratory phase of industrial experiments. The F-test in the usual linear model for analysis of variance (ANOVA) is a key instrument to assess the impact of each factor and of their interactions on the response variable. However, if assumptions such as normal distribution and homoscedasticity of errors are violated, the conventional wisdom is to resort to nonparametric tests. Nonparametric methods, rank-based as well as permutation, have been a subject of recent investigations to make them effective in testing the hypotheses of interest and to improve their performance in small sample situations. In this study, we assess the performances of some nonparametric methods and, more importantly, we compare their powers. Specifically, we examine three permutation methods (Constrained Synchronized Permutations, Unconstrained Synchronized Permutations and Wald-Type Permutation Test), a rank-based method (Aligned Rank Transform) and a parametric method (ANOVA-Type Test). In the simulations, we generate datasets with different configurations of distribution of errors, variance, factor's effect and number of replicates. The objective is to elicit practical advice and guides to practitioners regarding the sensitivity of the tests in the various configurations, the conditions under which some tests cannot be used, the tradeoff between power and type I error, and the bias of the power on one main factor analysis due to the presence of effect of the other factor. A dataset from an industrial engineering experiment for thermoformed packaging production is used to illustrate the application of the various methods of analysis, taking into account the power of the test suggested by the objective of the experiment.     

Young people’s perceptions of power and influence as a basis for understanding contemporary citizenship

Persistent simplistic binary discourses of young people’s citizenship portray them either as civically deficit and disengaged citizens or the creators of new democratic modes and approaches. This paper draws on field research with two groups of young people in Australia to better recognise the nuance of young people’s experiences of citizenship, power and influence. The study investigated the extent to which different groups of young people believe that they have the power to influence society; the ways in which they seek this influence; the current barriers to their influence; and what would enable them to have greater influence. Our analysis in this paper draws on Lukes’ concepts of power [2005. Power: A Radical View. 2nd ed. London: Palgrave Macmillan] and Arvanitakis’ framework of citizenship engagement and empowerment [in Arvanitakis, J., and E. Sidoti. 2011. “The Politics of Change: Where to for Young People and Politics.” In Their Own Hands: Can Young People Change Australia?, edited by L. Walsh and R. Black, 11–20. Melbourne: ACER Press], but also builds on an emerging scholarship concerned with the geographic dimensions of young people’s citizenship engagement and action, as well as with the affective, relational and temporal dimensions of this engagement and action. Our findings suggest that power works in different ways to both constrain and liberate young people as citizens – sometimes at the same time. The paper concludes with an argument for the continuing need to understand young people’s lived and located experiences of engagement, power and influence in more nuanced and sophisticated ways. This includes reframing the discussion about young people’s experiences in terms of the nature of their democratic engagement and action rather than simply their citizenship.

现代行政法平衡论的不平衡审视

现代行政法“平衡论”通过行政关系与监督行政关系的互动实现平衡,但是在涉及主体之间、行政与环境关系、执行中所导致的结果等方面并不平衡,其提倡的以民制权论在目前可行性也不强,经历着后现代冲击的行政法也需要有新的发展思考。     

分权与旅游治理:基于欠发达地区的实证分析

许多发展中国家实行高度的中央集权,学界对国家政治体制的集权化及其作用已经进行许多有益的探讨,但是对分权的利弊及存在问题却没有深入涉及。本文首先回顾区域治理中的分权理论,提出了一个权力配置、分权控制及其政治规范性的区域治理分析框架,用于描述国家权力在旅游治理中的运行机制,以北部湾旅游发展的实践为例,通过考察中央政府和地方政府、地方企业以及非政府组织在权力治理网络中成长态势,评估广西地方政府在区域旅游治理中的效力,研究发现地方政府在参与决策制定方面仍面临种种困难。

北京地区农村电力消费模型研究

基于北京农村地区用电消费的实际调查,我们发现农村地区的用电与家庭户均支出、电冰箱保有率、空调拥有率、电热毯保有率有较为密切的相关关系,本文对北京地区的农村用电消费建立了一个研究模型,以此指导农村地区用电市场的开发与建设。
