The first wave of revival of States and nations of Asia and Africa which shaped major changes in the history of humankind organized itself in the Bandung spirit in the frame of countries Non-Aligned on colonialism and neo colonialism, the pattern of globalization at that time. Now, the same nations, as well as those of Latin America and the Caribbean, are challenged by neo-liberal globalization, which is no less imbalanced by nature. Therefore, they must unite to face the challenge successfully as they did in the past. In some countries “sovereign” projects are developed that associate active State policies aimed at systematically constructing a national integrated consistent modern industrial productive system, supported by an aggressive export capacity. Views with respect to the degree, format and eventual regulation of opening to foreign capital and financial flows of all kinds (foreign direct investments, portfolio investments, speculative financial investments) differ from country to country. Policies pursued with respect to the access to land and other natural resources also offer a wide spectrum of different choices and priorities.  相似文献

OBJECTIVE: The aim was to examine how traumatic and stressful events, responses to violence, child characteristics, and mothering quality, as measured in middle childhood predict psychological distress and positive resources in adolescence. METHOD: The participants were 65 Palestinian adolescents (17+/-.85 years; 52% girls), who had been studied during the First Intifada (T1), during the Palestinian Authority rule (T2) and before the Second Al Aqsa Intifada (T3) in Gaza. Psychological distress was indicated by PTSD, and depressive symptoms and positive resources by resilient attitudes and satisfaction with quality of life, all measured at T3. The predictors that were measured at T1 were exposure to military violence, active coping with violence and children's intelligence, cognitive capacity, and neuroticism. Mothering quality and stressful life-events were measured at T2, the former reported by both the mother and the child, and the latter by the mother. RESULTS: Adolescents' PTSD symptoms were most likely if they had been exposed to high levels of traumatic and stressful experiences and had poor cognitive capacity and high neuroticism in middle childhood. Only high levels of childhood military violence and stressful life-events predicted high depressive symptoms and low satisfaction with quality of life in adolescence. CONCLUSIONS: Military violence in childhood forms risks for both increased psychological distress and decreased positive resources. However, child characteristics such as cognitive capacity and personality are important determinants of psychological vulnerability in military trauma.  相似文献

Abstract

The purpose of this paper is to discuss the introduction of microcomputers into the Hope Institute, a school for mildly mentally retarded children. Readily available software in English could not be implemented, hence software had to be specially written for this pilot project. The package was demonstrated to the officials concerned at the Institute and was well received. It is expected that the growing awareness about the use of computers in the secondary schools of Bahrain will reinforce the results of our experiment and promote the introduction of computers into the special education institutes of the country.  相似文献

In the whole world, the internet is exercised by millions of people every day for information retrieval. Even for a small to smaller task like fixing a fan, to cook food or even to iron clothes persons opt to search the web. To fulfill the information needs of people, there are billions of web pages, each having a different degree of relevance to the topic of interest (TOI), scattered throughout the web but this huge size makes manual information retrieval impossible. The page ranking algorithm is an integral part of search engines as it arranges web pages associated with a queried TOI in order of their relevance level. It, therefore, plays an important role in regulating the search quality and user experience for information retrieval. PageRank, HITS, and SALSA are well-known page ranking algorithm based on link structure analysis of a seed set, but ranking given by them has not yet been efficient. In this paper, we propose a variant of SALSA to give sNorm(p) for the efficient ranking of web pages. Our approach relies on a p-Norm from Vector Norm family in a novel way for the ranking of web pages as Vector Norms can reduce the impact of low authority weight in hub weight calculation in an efficient way. Our study, then compares the rankings given by PageRank, HITS, SALSA, and sNorm(p) to the same pages in the same query. The effectiveness of the proposed approach over state of the art methods has been shown using performance measurement technique, Mean Reciprocal Rank (MRR), Precision, Mean Average Precision (MAP), Discounted Cumulative Gain (DCG) and Normalized DCG (NDCG). The experimentation is performed on a dataset acquired after pre-processing of the results collected from initial few pages retrieved for a query by the Google search engine. Based on the type and amount of in-hand domain expertise 30 queries are designed. The extensive evaluation and result analysis are performed using MRR, [email protected], MAP, DCG, and NDCG as the performance measuring statistical metrics. Furthermore, results are statistically verified using a significance test. Findings show that our approach outperforms state of the art methods by attaining 0.8666 as MRR value, 0.7957 as MAP value. Thus contributing to the improvement in the ranking of web pages more efficiently as compared to its counterparts.  相似文献

Effects of treatmentin vivo with the antimalarials:chloroquine (CQ), primaquine (PQ) and quinine(Q) on lysosomal enzymes and lysosomal membrane integrity were examined. Treatment with the three antimalarials showed an apparent increase in the membrane stability. CQ treatment resulted in increase in both the ‘free’ and ‘total’ activities of all the enzymes i.e. acid phosphatase, RNase II, DNase II and cathepsin D. PQ treatment lowered the ‘free’ and ‘total’ activities of acid phosphatase and cathepsin D, but the DNase II activities increased. Treatment with Q resulted in increased ‘free’ and ‘total’ activities of RNase II and DNase II. While ‘free’ activities of acid phosphatase and cathepsin D were low; the ‘total’ activities increased significantly. Our results suggest that a generalized increase in free nucleases activities following prolonged treatment with antimalarials may lead to cell damage and/or necrosis.  相似文献

1 Introduction Weight saving materials such as aluminum and its alloys are becoming increasingly important and have been attracting increasing attention over the past decade, specially in the automotive, aerospace and chemical industries, and electrical devices because of their high strength-to-weight ratio, high electrical and thermal conductivities, processability and recyclability and good resistance to degradation in some corrosive environments [1,2]. In the automotive industry, there is d…  相似文献

This paper aims to explore the discrepancy between self-reported and test-based literacy estimates in Bangladesh. It uses the Education Watch national literacy survey data of 2002, during which the literacy status of a nationally representative sample was identified using the two methods referred to above. The findings revealed that the literacy rate generated through a literacy test was significantly lower than that found when the self-report method was used. The level of discrepancy varied from one population group to another, indicating that literacy assessment using the self-report method cannot be equally appropriate for all population groups. Those with a few years of schooling were at a particular risk of over-estimating their status. The paper makes a case for a written literacy assessment rather than an oral evaluation.  相似文献
