In this work, we present the first quality flaw prediction study for articles containing the two most frequent verifiability flaws in Spanish Wikipedia: articles which do not cite any references or sources at all (denominated Unreferenced) and articles that need additional citations for verification (so-called Refimprove). Based on the underlying characteristics of each flaw, different state-of-the-art approaches were evaluated. For articles not citing any references, a well-established rule-based approach was evaluated and interesting findings show that some of them suffer from Refimprove flaw instead. Likewise, for articles that need additional citations for verification, the well-known PU learning and one-class classification approaches were evaluated. Besides, new methods were compared and a new feature was also proposed to model this latter flaw. The results showed that new methods such as under-bagged decision trees with sum or majority voting rules, biased-SVM, and centroid-based balanced SVM, perform best in comparison with the ones previously published. 相似文献

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS). 相似文献

Zusammenfassung. Die intelligente Ressourcenadaption ist eine der gro?en Herausforderungen für die n?chste Generation mobiler Navigationssysteme.
Da man typischerweise mehrere Fortbewegungsarten oder Verkehrsmittel kombinieren muss, um an einen Zielort zu gelangen, muss
sichergestellt werden, dass mobile, allgegenw?rtige Navigationshilfen dies über eine jeweils situationsangepasste Benutzerschnittstelle
unterstützen. Der notwendige Wechsel zwischen verschiedenen Positionierungstechnologien soll für den Endbenutzer m?glichst
unbemerkt bleiben. Im folgenden wird ein hybrides Personennavigationssystem vorgestellt, das die in bestimmten Fortbewegungssituationen
verfügbaren Positionierungstechnologien und deren Genauigkeit optimal nutzt, um die Pr?sentation der Wegbeschreibung auf verschiedene
Endger?te und Ausgabemodalit?ten sowie die kognitive Ressourcenlage des Benutzers zu adaptieren.

In 2004 the Dutch Ministry of Education, Culture and Science set a concrete target: by 2010, close to 50% of the age cohort should participate in higher education, following the targets set in the UK and Sweden. However clear the target is set, the ways to achieve it are far less specified. In the article a number of possible instruments to achieve the target are discussed and their relevance in the Dutch context is analysed. It is concluded that there are a limited number of policy instruments available. However, given the devolution of access policy to the higher education institutions and the influence of broader societal trends on participation our expectations on what government can do to reach its target need to be modest. 相似文献

There is an increasing interest in linking character education programs with social and academic outcomes. The Child Development
Project (CDP) is a character education program that promotes academic and social growth in teachers and students. This theory-driven
evaluation employed a quasi-experimental design with matched control schools. School personnel participated in an intensive
professional development process to learn the CDP model. Performance measures included state-mandated achievement measures,
teacher self-assessment reports, and student attitudes and outcomes. Results yielded support for the CDP model as a strategy
to improve social and, if properly implemented, cognitive outcomes in students; the model also improved teacher self-assessment
and provided information that may facilitate professional growth about school collegiality. Implications for policy and practice
will be discussed. 相似文献

试论高职学院体育师资队伍建设 总被引:2,自引:0,他引:2
随着社会和高等教育形势的快速发展,高等职业技术教育成为高等教育的一部分,已成为当前社会关注的一个热点。高职学院要能适应高等教育的要求,适应新的办学模式,全面提高教学质量和办学水平,关键是拥有一支与人才培养目标相一致的数量、质量合格的教师队伍。而目前高职学院体育师资队伍的现状,与高等教育的要求及全面推进学校体育工作深化改革的目标,尚存有较大的差距。因此要针对现状,在加强教师政治思想、德育教育,优化教师知识结构,优化师资队伍结构,提高教学科研能力、水平等几个主要方面,采取积极有效的措施;加强队伍建设,全面提高体育教师的整体素质水平,尽快适应高等教育发展的需要及高校体育教学改革、科学研究的要求。 相似文献

Quantum algorithms are a field of growing interest within the theoretical computer science as
well as the physics community. Surprisingly, although the number of researchers working on the subject
is ever-increasing, the number of quantum algorithms found so far is quite small. In fact, the task of
designing new quantum algorithms has been proven to be extremely difficult. In this paper we give an overview
of the known quantum algorithms and briefly describe the underlying ideas. Roughly, the algorithms presented
are divided into hidden subgroup type algorithms and in amplitude amplification type algorithms. While
the former deal with problems of group-theoretical nature and have the promise to yield strong separations
of classical and quantum algorithms, the latter have been proved to be a prolific source of algorithms
in which a polynomial speed-up as compared to classical algorithms can be achieved. We also discuss
quantum algorithms which do not fall under these two categories and give a survey of techniques of
general interest in quantum computing such as adiabatic computing, lower bounds for quantum algorithms,
and quantum interactive proofs. 相似文献
