This paper scrutinises the phenomenon of collective squatting for housing in Rome (Italy), which has reached remarkable proportions and developed new characteristics since the start of the 2008 crisis. Based upon two pieces of ethnographic research within the housing movement organisations Coordinamento Cittadino di Lotta per la Casa (Urban Coordination of Housing Struggles) and Blocchi Precari Metropolitani (Precarious Metropolitan Block), the authors aim to enlarge empirical knowledge of the case under study and provide renewed analytical instruments for understanding housing mobilisations. These organisations appear to be more than grassroots approaches to housing deprivation; they also represent alternative forms of social reproduction in post-welfare neoliberal cities. Indeed, squats configure themselves as sites for broader political elaboration. For this reason, we propose to analyse housing squatting using the notion of ‘urban commons’. The introduction of this notion to analyse housing movements helps in the theoretical elaboration of a re-appraised ‘right to the city’, in line with current urban challenges. 相似文献

There are now three essentially separate literatures on the topics of multiple systems estimation, record linkage, and missing
data. But in practice the three are intimately intertwined. For example, record linkage involving multiple data sources for
human populations is often carried out with the expressed goal of developing a merged database for multiple system estimation
(MSE). Similarly, one way to view both the record linkage and MSE problems is as ones involving the estimation of missing
data. This presentation highlights the technical nature of these interrelationships and provides a preliminary effort at their
integration. 相似文献

We deal with the double sampling plans by variables proposed by Bowker and Goode (Sampling Inspection by Variables, McGraw–Hill,
New York, 1952) when the standard deviation is unknown. Using the procedure for the calculation of the OC given by Krumbholz and Rohr (Allg.
Stat. Arch. 90:233–251, 2006), we present an optimization algorithm allowing to determine the ASN Minimax plan. This plan, among all double plans satisfying
the classical two-point-condition on the OC, has the minimal ASN maximum. 相似文献

互联网络已成为人们日常生活的重要组成部分。它在给高校学生带来便捷信息服务的同时,也对学生管理带来一定的难度。高校网络思想政治教育应以学生为本,突出主体性;注重队伍建设,强化校园网络管理;坚持正确的舆论导向,牢牢把握网络思想政治教育的主动权。 相似文献

This paper reports on the developmental strategies, challenges and directions of the institutional repositories of the higher educational institutions in Hong Kong. The study integrates the size, content, full text and public accessibility of these repositories. The paper also compares archived output with research output as registered by the Hong Kong University Grants Committee. Percentages of archived work are low for journal and conference papers, but moderate for graduate theses. These deposit rates reflect the differing institutional policies. In recognizing these challenges, the Hong Kong Open Access Committee has been formed to address regional issues in knowledge sharing. 相似文献

Data envelopment analysis (DEA) is a deterministic econometric model for calculating efficiency by using data from an observed set of decision-making units (DMUs). We propose a method for calculating the distribution of efficiency scores. Our framework relies on estimating data from an unobserved set of DMUs. The model provides posterior predictive data for the unobserved DMUs to augment the frontier in the DEA that provides a posterior predictive distribution for the efficiency scores. We explore the method on a multiple-input and multiple-output DEA model. The data for the example are from a comprehensive examination of how nursing homes complete a standardized mandatory assessment of residents. 相似文献

In many sciences researchers often meet the problem of establishing if the distribution of a categorical variable is more
concentrated, or less heterogeneous, in population P
1 than in population P
2. An approximate nonparametric solution to this problem is discussed within the permutation context. Such a solution has similarities
to that of testing for stochastic dominance, that is, of testing under order restrictions, for ordered categorical variables.
Main properties of given solution and a Monte Carlo simulation in order to evaluate its degree of approximation and its power
behaviour are examined. Two application examples are also discussed. 相似文献

Modified inference about the mean of the exponential distribution using moving extreme ranked set sampling 总被引:1,自引:1,他引:0
The maximum likelihood estimator (MLE) and the likelihood ratio test (LRT) will be considered for making inference about the
scale parameter of the exponential distribution in case of moving extreme ranked set sampling (MERSS). The MLE and LRT can
not be written in closed form. Therefore, a modification of the MLE using the technique suggested by Maharota and Nanda (Biometrika
61:601–606, 1974) will be considered and this modified estimator will be used to modify the LRT to get a test in closed form
for testing a simple hypothesis against one sided alternatives. The same idea will be used to modify the most powerful test
(MPT) for testing a simple hypothesis versus a simple hypothesis to get a test in closed form for testing a simple hypothesis
against one sided alternatives. Then it appears that the modified estimator is a good competitor of the MLE and the modified
tests are good competitors of the LRT using MERSS and simple random sampling (SRS). 相似文献
