Dancing on the deck of the Titanic? Adult education, the nation-state and new social movements     

Carlos Alberto Torres 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2011,57(1-2):39-55

This article begins with a discussion of the implications of CONFINTEA VI having been organised in Brazil ?C the author uses the term ??Brazilian effect?? ?C and the role of social movements challenging neoliberalism. Next, drawing from the experience of Latin America, this paper analyses the counter-hegemonic practice of the new social movements. The concluding section highlights the dilemmas faced by UNESCO in trying to create a democratic and efficient process of policy-making and institutional service in adult education in the nation-states. Furthermore, the proposal of popular education portrayed by the new social movements is described as a tool for empowerment. CONFINTEA VI??s recommendation of moving from rhetoric to action in adult education programmes, practices and policies demands that we take the agendas of the new social movements in the post-neoliberalism era seriously.  相似文献

An unsupervised heuristic-based approach for bibliographic metadata deduplication     

Eduardo N. Borges  Moisés G. de Carvalho  Renata Galante  Marcos André Gonçalves  Alberto H.F. Laender 《Information processing & management》2011

Digital libraries of scientific articles contain collections of digital objects that are usually described by bibliographic metadata records. These records can be acquired from different sources and be represented using several metadata standards. These metadata standards may be heterogeneous in both, content and structure. All of this implies that many records may be duplicated in the repository, thus affecting the quality of services, such as searching and browsing. In this article we present an approach that identifies duplicated bibliographic metadata records in an efficient and effective way. We propose similarity functions especially designed for the digital library domain and experimentally evaluate them. Our results show that the proposed functions improve the quality of metadata deduplication up to 188% compared to four different baselines. We also show that our approach achieves statistical equivalent results when compared to a state-of-the-art method for replica identification based on genetic programming, without the burden and cost of any training process.  相似文献   

Contemporary discourses in Information Systems Research: Methodological inclusiveness in a sample of Information Systems Journals     

Alberto Paucar-Caceres  Gillian Wright 《International Journal of Information Management》2011,31(6):593-598

We propose a framework to reflect on the development of four information systems (IS) paradigms, arguing that this field has followed a similar path to that of Management Sciences (MS). The framework comprises four IS paradigms/discourses: (1) positivist/normative; (2) soft/interpretive; (3) critical/pluralistic; and (4) constructivist/2nd order cybernetics. The paper characterizes these approaches to IS by using four key terms: System; Organisation; Management and Information, exploring the way these concepts are perceived through the lens of the four paradigms. The paper reports on the nature of current IS trends, from an initial survey of six top IS journals identifying articles adhering to the interpretive, critical and constructivist paradigms published between 1999 and 2009. Results indicate that IS is moving towards research practice in which interpretive, critical and constructivist discourses are utilised. Implications of the proposed framework and publication trends, together with some points for further research, are offered.  相似文献

常识的概念已经成为一种意识形态,在当代社会构建霸权主义、并将霸权主义作为道德与智力领导力的过程中起着重要作用。尽管在事实上新自由主义作为一种经济发展模式已经彻底失败,与新自由主义相关的文化政治仍然盛行于世,并在塑造现代政府和教育角色的理念中变成了新的常识。新自由主义全球化是全球化中最突出的模式,以市场相对于政府的主导地位和放松管制的治理模式为前提,在"学术资本主义"背景下深深地影响了高校。由此带来的改革通常以促进国际竞争力为合理借口,也被称为"竞争型改革"。市场力量日益渗透到高等教育领域,围绕学术资本主义"游戏"展开的大学治理模式的重构,均显示了新自由主义对高校影响的四个主要方面,即效率与问责制、认证与普及化、国际竞争力、私有化。通过引入以管理主义治理院校的新型模式,高校深化并扩大了自身的危机。虽然高校采纳并实施了这些改革措施,但是在不同领域,在自上而下地通过政策和重心调整强制改革时,全球化面临着越来越大的阻力。在许多情况下,新自由主义改革通过收取较高学费与减少政府对院校和个人的支持,限制了一些阶级和种族接受高等教育的机会。 更多还原  相似文献

Instrumental Variables Two-Stage Least Squares (2SLS) vs. Maximum Likelihood Structural Equation Modeling of Causal Effects in Linear Regression Models     

Alberto Maydeu-Olivares  Dexin Shi  Yves Rosseel 《Structural equation modeling》2013,20(6):876-892

In the presence of omitted variables or similar validity threats, regression estimates are biased. Unbiased estimates (the causal effects) can be obtained in large samples by fitting instead the Instrumental Variables Regression (IVR) model. The IVR model can be estimated using structural equation modeling (SEM) software or using Econometric estimators such as two-stage least squares (2SLS). We describe 2SLS using SEM terminology, and report a simulation study in which we generated data according to a regression model in the presence of omitted variables and fitted (a) a regression model using ordinary least squares, (b) an IVR model using maximum likelihood (ML) as implemented in SEM software, and (c) an IVR model using 2SLS. Coverage rates of the causal effect using regression methods are always unacceptably low (often 0). When using the IVR model, accurate coverage is obtained across all conditions when N = 500. Even when the IVR model is misspecified, better coverage than regression is generally obtained. Differences between 2SLS and ML are small and favor 2SLS in small samples (N ≤ 100).  相似文献   

Factor Analysis with Ordinal Indicators: A Monte Carlo Study Comparing DWLS and ULS Estimation     

Carlos G. Forero  Alberto Maydeu-Olivares  David Gallardo-Pujol 《Structural equation modeling》2013,20(4):625-641

Factor analysis models with ordinal indicators are often estimated using a 3-stage procedure where the last stage involves obtaining parameter estimates by least squares from the sample polychoric correlations. A simulation study involving 324 conditions (1,000 replications per condition) was performed to compare the performance of diagonally weighted least squares (DWLS) and unweighted least squares (ULS) in the procedure's third stage. Overall, both methods provided accurate and similar results. However, ULS was found to provide more accurate and less variable parameter estimates, as well as more precise standard errors and better coverage rates. Nevertheless, convergence rates for DWLS are higher. Our recommendation is therefore to use ULS, and, in the case of nonconvergence, to use DWLS, as this method might converge when ULS does not.  相似文献   

Adaptation and evaluation of a learning analytics dashboard to improve academic support at three Latin American universities     

Julio Guerra  Margarita Ortiz-Rojas  Miguel Angel Zúñiga-Prieto  Eliana Scheihing  Alberto Jiménez  Tom Broos  Tinne De Laet  Katrien Verbert 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(4):973-1001

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks.  相似文献   

New curve sprint test for soccer players: Reliability and relationship with linear sprint

ABSTRACT

The speed performance is involved not only in linear sprints, but also in a wide spectrum of multi-directional movements, such as curve sprinting. Curved sprint can be defined as sprint with gradual and continuous change of direction (COD). Although ~85% of the actions performed at maximum velocity in a professional soccer league are curvilinear sprints, there is not any specific test to assess this ability. This study aimed to analyse the reliability of a new curve sprint test, and compare its results with those obtained by soccer players in linear sprint. Forty experienced soccer players performed 3 attempts of curve sprint (using the penalty arc) to right and left side (17 m), and 3 linear sprints (17 m) in two different days. The ICCs (inter-session reliability) were 0.93 for sprint curve right side (CSRS) and 0.89 for sprint curve left side (CSLS), considered “acceptable”. The CVs (intra-session reliability) were 0.87% in CSRS and 1.15% in CSLS. The coefficient of determination (R²) between linear and curve sprinting was ~35%. The association between curve sides was “very large” (r = 0.878; p < 0.01). In summary, we showed that “curve sprint test” is highly reliable, and that curvilinear and linear sprints are different and independent actions.  相似文献
