This paper describes a methodology for the development of a proactive balanced scorecard (PBSCM). The balanced scorecard is one of the most popular approaches developed in the field of performance measurement. However, in spite of its reputation, there are issues that require further research. The present research addresses the problems of the balanced scorecard by utilizing the soft computing characteristics of fuzzy cognitive maps (FCMs). By using FCMs, the proposed methodology generates a dynamic network of interconnected key performance indicators (KPIs), simulates each KPI with imprecise relationships and quantifies the impact of each KPI to other KPIs in order to adjust targets of performance. 相似文献

The year 1948, as a starting point both of this study and of the organised military sport for Greece, was particularly hectic, since the newly liberated country was embroiled in the Civil War while, simultaneously, it was trying to reconstitute itself. The next two decades were marked by the foundation and the activities of the Higher Coordinating Committee for Sport in the Armed Forces (Anotera Syntonistiki Epitropi Athlitismou Enoplon Dynameon – A.S.E.A.E.D.). This Committee organised and materialised the first steps of the newly established organised sports activities of the Hellenic Armed Forces and evolved as a result, into the Supreme Council for Sport in the Armed Forces (Anotato Symvoulio Athlitismou Enoplon Dynameon) in year 1968. Due to the lack of specific and thorough research on the topic during this era, the purpose of this study was to identify references and the original sources (archives both of the A.S.E.A.E.D. and of the Hellenic National Defense General Staff) and to highlight and reveal the activities of organised Greek military sport, in the organisational field, and the Hellenic Armed Forces' participation in international sports tournaments. 相似文献

The present study should be thought as a socioconstructivist teaching approach (a teaching model) for the concept of energy in primary education. It contains important and crucial aspects of the History and Philosophy of Natural Sciences, introduces the concept of energy using the macroscopic framework of thermodynamics, takes into consideration learners’ alternative ideas or frameworks relating to energy, takes advantage of the causal and the unifying characters of energy, which have been founded on the historiographical analysis of this concept, uses energy chains as visual representations for the deep understanding of it, uses visual grammar of Kress and van Leeuwen to design energy chains and introduces a teaching methodology for this concept. 相似文献

This article discusses 1:1 learning initiatives in Europe in the context of a mapping framework of ICT-enabled innovation for learning. The aim of the framework, visualised as a spider's web, is two-fold: (i) to provide a further understanding of the nature of ICT-enabled innovation for learning; and (ii) to depict the impact of existing and emerging innovative initiatives using ICT in the Education and Training context. We present 1:1 learning initiatives in Europe as a case of ICT-enabled innovation for learning with significant scale, scope, and impact at system level and being implemented in real settings. We identified and analysed 29 1:1 learning initiatives from 19 European countries reaching a total of approximately 620,000 schools and 16,800,000 students. The application of the framework to the case of 1:1 learning in Europe (implemented in multi-faceted educational settings) showed the current state of development and the emerging trends regarding the nature, the reach, the target groups and the impact of 1:1 innovation in learning. Regarding the nature of innovation, 1:1 learning strategies in Europe can be considered as mostly incremental. There is a need to progressively move the focus away from the devices and infrastructure to the learners and to 1:1 pedagogies. The framework can contribute (i) to policy interventions -at micro, meso and macro level- aimed at diversity and systemic implementation and (ii) to strategic planning by a multiplicity of actors such as policy makers, researchers and practitioners, increasing the impact of ICT-enabled innovation in Education and Training. 相似文献

How social media can enable opportunities for collaboration between citizens and governments is an evolving issue in theory and practice. This paper examines the dynamic aspects of collaboration in the context of the 2011 riots in England. In August 2011, parts of London and other cities in England suffered from extensive disorder and even loss of human lives. Based on a dataset of 1746 posts by 81 local government Twitter accounts during or shortly after the riots, we explore how local authorities attempted to reduce the effects of the riots and support community recovery. Using Twitter's conversational and rapid update features, they produced a variety of informational and actionable messages with clear calls for offline or online action. In some cases, collective against the riots evolved in a mutual way: not only citizens were mobilized by local authorities, but also local authorities actively promoted actions initiated by citizens. 相似文献

This study focuses on the shared variance between reading comprehension and word-level reading skills in a population of 534 Greek children in Grades 2 through 4. The correlations between measures of word and pseudoword accuracy and fluency, on the one hand, and vocabulary and comprehension skills, on the other, were sizeable and stable or increasing with grade. However, the unique contribution of word reading to comprehension became negligible after vocabulary measures were entered in hierarchical regression analyses, particularly for higher grades, suggesting that any effects of decoding on comprehension may be mediated by the lexicon, consistent with lexical quality hypothesis. Structural modeling with latent variables revealed an invariant path across grades in which vocabulary was defined by its covariation with reading accuracy and fluency and affected comprehension directly. It is argued that skilled word reading influences comprehension by strengthening lexical representations, at least when phonological decoding can be relatively effortless. 相似文献

In this study, we assessed the effects of a 4 week basic military physical training programme for male recruits of the Hellenic Air Force on the number and distribution of circulating immune cells and adrenergic and adrenocortical hormonal responses. One group of recruits (exercised, n = 48) participated in moderate intermittent physical exercise, whereas a second group (non-exercised controls, n = 9) performed only light work in the barracks. Both groups participated in the same non-physical, classroom-type training and testing. Military training by the exercised group resulted in significant increases in CD4?+? T-lymphocytes, renal cortisol excretion and the urinary noradrenaline/adrenaline ratio, together with reductions in neutrophils and the neutrophil/lymphocyte ratio. In the exercised group, the urinary noradrenaline/adrenaline ratio correlated positively with the training-induced changes in CD4?+? T-lymphocytes and negatively with changes in the neutrophil/lymphocyte ratio. No significant relationship was found between training-induced increases in cortisol excretion and any of the peripheral blood cell alterations. Our results indicate that 4 weeks of military training consisting of intermittent moderate exercise resulted in a significant increase in CD4?+? T-lymphocytes and reduction in neutrophils. These changes were probably driven by alterations in hormonal status, including the significant impact of sympathetic nervous system activation. 相似文献

Teachers play a crucial role in the development of primary school students’ creative potential in either a positive or a negative way. This paper aims to draw attention to in-service and prospective teachers’ conceptions of creativity and answer three main research questions: “What are the teachers’ conceptions and implicit theories of creativity in general?”, “What are the teachers’ conceptions and implicit theories of creativity in the context of primary education?”, and “How well-trained and equipped do teachers feel to play their key role in the development of students’ creative potential?” A self-report questionnaire was used as an instrument to gather qualitative and quantitative data from 132 Greek in-service and prospective teachers. According to the selected quantitative data we present in this study, the majority of the participants reported that the facilitation of students’ creativity is included in the teachers’ role, but they (teachers themselves) do not feel well-trained and confident enough to realise this particular expectation. The authors conclude that further research is needed in order to: (i) reveal more on teachers’ conceptions on creativity and (ii) understand and classify teachers’ particular needs to facilitate the creative potential of primary school students. 相似文献
