The government of Botswana had to strike a fine balance between not isolating the liberation movements, not letting them use Botswana as a military base and not appearing to harbour ‘terrorists’. The government realised that overtly supporting the liberation movements was potentially suicidal, for the country could easily be punished by South Africa: trade links could be severed and communication networks paralysed. The settler regimes did try to infiltrate and weaken the liberation movements in Botswana and carried out acts such as kidnapping, intimidation and deportation, to try to prevent the liberation movements from threatening the status quo in southern Africa. Using evidence from the Botswana National Archives, oral interviews, and newspaper reports, the article examines the means the Botswana government adopted to deal with the situation and safeguard the security of its citizens. 相似文献

Despite the growing body of research on ‘hybrid regimes’, few studies address the issue of their domestic legitimacy. Targeting this gap in the literature, this article explores the legitimation strategies of three hybrid regimes around the globe: Russia, Venezuela, and Seychelles. Although these countries differ markedly in almost every aspect that can be thought of, the political systems of all three cases combine formally democratic institutions with authoritarian political dynamics. The qualitative, comparative analysis presented in this article uncovers a number of remarkable similarities between the regimes’ respective legitimization strategies. However, while the strategies for engendering legitimacy are similar across the cases, the content of these strategies is different: the Russian leadership mainly relies on preserving order and nationalism, the Venezuelan regime employs a more populist strategy, and the Seychellois regime uses a more personal and particularistic approach. Our findings not only provide insights into the mechanisms hybrid regimes use to consolidate their authority, but also highlight important differences and similarities between hybrid regimes around the world. 相似文献

The purpose of this article is to investigate estimation and hypothesis testing by maximum likelihood and method of moments in functional models within the class of elliptical symmetric distributions. The main results encompass consistency and asymptotic normality of the method of moments estimators. Also, the asymptotic covariance matrix of the maximum likelihood estimator is derived, extending some existing results in elliptical distributions. A measure of asymptotic relative efficiency is reported. Wald-type statistics are considered and numerical results obtained by Monte Carlo simulation to investigate the performance of estimators and tests are provided for Student-t and contaminated normal distributions. An application to a real dataset is also included. 相似文献

In this article, a general class of estimators for the linear regression model affected by outliers and collinearity is introduced and studied in some detail. This class of estimators combines the theory of light, maximum entropy, and robust regression techniques. Our theoretical findings are illustrated through a Monte Carlo simulation study. 相似文献

In this paper we propose a robust Bayesian procedure of estimation, testing, validation and selection of spatio-temporal autoregressive models (STAR) with neighbourhood effects applied to the appraisal of dwelling prices. The methodology does not depend on asymptotic results and, unlike previously procedures proposed in the literature, takes into account the uncertainty associated to the estimation of the neighbourhood parameters of the model, giving more realism to the analysis. Moreover, a sequential algorithm to elaborate fast on-line forecast, is provided. The methodology is illustrated by means of a practical case of the real estate market of Zaragoza. 相似文献

In the case of prior knowledge about the unknown parameter, the Bayesian predictive density coincides with the Bayes estimator for the true density in the sense of the Kullback-Leibler divergence, but this is no longer true if we consider another loss function. In this paper we present a generalized Bayes rule to obtain Bayes density estimators with respect to any α-divergence, including the Kullback-Leibler divergence and the Hellinger distance. For curved exponential models, we study the asymptotic behaviour of these predictive densities. We show that, whatever prior we use, the generalized Bayes rule improves (in a non-Bayesian sense) the estimative density corresponding to a bias modification of the maximum likelihood estimator. It gives rise to a correspondence between choosing a prior density for the generalized Bayes rule and fixing a bias for the maximum likelihood estimator in the classical setting. A criterion for comparing and selecting prior densities is also given. 相似文献

Eco-innovation is actually a fashionable topic, and several researchers are working on understanding the defining characteristics of firms that consider the environment as a priority when innovating. To date most of these studies have been carried out on manufacturing industries. This article investigates the similarities and differences among service and manufacturing firms. An empirical analysis of a sample of 5509 Spanish companies shows that the variables affecting the eco-innovative orientation of firms are quite similar. Results reveal that manufacturing firms have higher orientation toward the environment than service firms. Furthermore, highly polarized positions in environmental aspects can be found. Despite the limitations of the study, conclusions may help public policy to encourage environmental proactivity in service industry and innovation. 相似文献

This research analyses the morpho-syntactical competence of children in care and the educational style of their parents. The studies from the literature give no specific data concerning how the morphological and syntactic components are affected in children suffering from neglect. These studies point to important deficiencies in language development, but do not specify what such difficulties actually are. This research is carried out within the framework of the residential care children's homes in the region of Extremadura (Spain). The morpho-syntactic competence of the children and the parental educational style of a total of 74 children in residential care are analysed. The subjects are 41 males and 33 females, between 6 and 18 years of age. We apply the ‘Objective Language Criteria Test’ (BLOCScreening) to evaluate their linguistic development and the ‘Autoevaluative Multifactorial Child Adaptation Test’ (TAMAI) to determine educational style. The presence of difficulties in morphosyntaxis is evident. The children with a low dominion of morphology and syntax perceive a more punitive style in the parents. The difficulties in morphosyntax are manifested both expressive and receptive. Use short sentences to frequent omission of morphological markers. Comprehension problems are lower than those of expression, but it shows a erroneous understanding of some grammatical structures, and grammatical errors in spontaneous speech. Use fewer morphologically complex words in their narratives. Have difficulty in organising the content of the speech and the use of cohesive devices (using the precision and accuracy of the conjunctions used in compound sentences). We must stress the need to carry out early prevention and intervention programmes in order to promote an increase in both the quantity and the quality of language stimulation. From there, the need to set up intervention programmes that influence the linguistic competence of children who have suffered abuse. 相似文献
