A learning approach for performance evaluation of local network

In this paper, a novel approach is developed to evaluate the overall performance of a local area network as well as to monitor some possible intrusion detections. The data is obtained via system utility 'ping' and huge data is analyzed via statistical methods. Finally, an overall performance index is defined and simulation experiments in three months proved the effectiveness of the proposed performance index. A software package is developed based on these ideas.

Globally optimal learning rates in multilayer neural networks

A method for calculating the globally optimal learning rate in on-line gradient-descent training of multilayer neural networks is presented. The method is based on a variational approach which maximizes the decrease in generalization error over a given time frame. We demonstrate the method by computing optimal learning rates in typical learning scenarios. The method can also be employed when different learning rates are allowed for different parameter vectors as well as to determine the relevance of related training algorithms based on modifications to the basic gradient descent rule.

Time and professional work in public sector organisations: an examination of four occupational groups in education and medicine

The aim of this thesis is to examine the experience of time of four professional occupational groups working in public sector organisations and the factors affecting this experience. The literature on time and work is examined to delineate the key parameters of research in this area. A broad organisation behaviour approach to the experience of time and work is developed in which individual, occupational, organisational and socio-political factors are inter-related. The experience of secondary school teachers, further education lecturers, general medical practitioners and hosoital consultants is then examined. Multiple methods of data collection are used: open-ended interviews, a questionnaire survey and the analysis of key documents relating to the institutional settings in which the four groups work. The research aims to develop our knowledge of working time by considering the dimensions of the experience of time at work, the contexts in wlhich this experience is generated and the constraints these contexts give rIse to. By developing our understanding of time as a key feature of work experience we also extend our knowledge of organisation behaviour in general. In conclusion a model of the factors relating the experience of time to the negotiation of time at work is presented.

Applications of data envelopment analysis in education

Non-parametric methods for efficiency evaluation were designed to analyse industries comprising multi-input multi-output producers and lacking data on market prices. Education is a typical example. In this chapter, we review applications of DEA in secondary and tertiary education, focusing on the opportunities that this offers for benchmarking at institutional level. At secondary level, we investigate also the disaggregation of efficiency measures into pupil-level and school-level effects. For higher education, while many analyses concern overall institutional efficiency, we examine also studies that take a more disaggregated approach, centred either around the performance of specific functional areas or that of individual employees.

An organizational learning approach to expatriate cross-cultural adjustment, organizational commitment, and job satisfaction

The purpose of this study was to investigate the relationship between organizational learning and expatriation in overseas subsidiaries as well as in organizations as a whole. In doing so, two issues were addressed--(i) the use of expatriation as firms internationalize, and (ii) the significance of various factors to expatriate success as firms gain international experience. The sample of companies for this study was drawn from U.S. Fortune 500 multinational corporations (MNCs) in two sets of related industries--computers/electronics and petroleum/chemicals. Based on the learning that takes place within organizations as they increase their involvement overseas, a positive relationship was expected between international experience and expatriation when internationalization was low, and a negative relationship was expected when internationalization was high. Results indicate a significant positive relationship between country experience and the proportion of expatriates in that subsidiary when subsidiaries were relatively young, and a negative relationship, however not significant, for more mature subsidiaries. The relationship between overall firm degree of internationalization (DOI) and the proportion of expatriates in the firm as a whole was negative regardless of stage of internationalization, but this relationship was significant only for highly internationalized firms. It was further suspected that individual, environmental, and family-related characteristics would have a significant effect on the success of expatriates whose firms were low on internationalization, and that organizational characteristics would play a significant role in highly internationalized firms. Support for these hypotheses was received with respect to certain outcomes and some determinants of success. The preponderance of support was found for those addressing the effects of both environmental and family-related characteristics on the cross-cultural adjustment of expatriates in firms with little international experience. Considerable support was also found for those hypotheses addressing the impact of organizational characteristics on the job satisfaction levels of expatriates assigned to mature subsidiaries. The relevant literatures on organizational learning and expatriation are reviewed, and a model is developed underlying the logic of the hypotheses. Research methods are then described in full detail, results are reported, and implications for theory and for management are discussed. ^

Employee Orientation: An Organizational and Experiential Learning Approach

Employee orientation problems for a resort chain were studied and addressed through action research. The implemented solution leveraged experiential learning to foster employee initiative and problem solving to instill a culture of learning, improve customer satisfaction and increase employee retention. Business results were achieved but learner/ management reaction was mixed.

This study explores the problem oriented and public health models of youth crime prevention and how to better promote it in the average classroom through strategies and interventions in order to reduce gun violence.

Social Learning Capabilities in Broward’s Black Male Success Task Force: Informing Collective Impact Initiatives

Broward Schools is addressing an achievement gap for Black males with a collective impact initiative. Collective impact initiatives address complex social problems. The social learning capability of the initiative can be enhanced by applying Wenger’s (2009) social learning spaces, learning as citizenship, and social artists concepts.

The Significance of Critical Theory for Restorative Justice in Education

Restorative Justice (rj), a distinctive philosophical approach that seeks to replace punitive, managerial structures of schooling with those that emphasize the building and repairing of relationships (Hopkins 2004) has been embraced in the past two decades by a variety of school systems worldwide in an effort to build safe school communities. Early studies indicate rj holds significant promise, however, proponents in the field identify that theoretical and evidence-based research is falling behind practice. They call for further research to deepen the current understanding of rj that will support its sustainability and transformative potential and allow it to move from the margins to the mainstream of schooling (Braithwaite 2006; Morrison & Ahmed 2006; Sherman & Strang 2007).

The intersectorial approach in providing guidance and school support. The perspective of counsellors, tutors and principals

The provision of guidance and educational support requires joint work and the collaboration of different professionals and institutions, especially when we face complex problems that require a high level of specialization and the combination of knowledge from different areas. The research has aimed to examine the proximity of the institutional system of guidance and support to school in nine Autonomous Communities, to the intersectorial approach of counselling. We present the results of a descriptive study using the survey method, which allows knowing the opinions of counsellors, tutors and principals of Primary and Secondary Compulsory Education about the collaboration with the local public services (social, health, education, and employment) in the specialized support to students and schools. The final sample consisted of 9732 subjects who were selected from a random sampling proportional to the size of the subpopulations of each Autonomous Community. Results indicate how, in general terms, there is collaboration among the school and the local public services, although not as frequently as it would be desirable. In the same way, the professionals that were interviewed believe that the collaboration with social and educational services is quite adequate, but the assessment is not as positive when health and employment services are analysed. Finally, taking into account the different professionals considered, tutors from both educational stages are the ones that show a higher degree of satisfaction with the collaboration between the school and the local public services, except in the case of social services.

The role of learning design and learning analytics in MOOCs

The last couple of years there has been a lot of attention for MOOCs. More and more universities start offering MOOCs. Although the open dimension of MOOC indicates that it is open in every aspect, in most cases it is a course with a structure and a timeline within which learning activities are positioned. There is a contradiction there. The open aspect puts MOOCs more in the non-formal professional learning domain, while the course structure takes it into the formal, traditional education domain. Accordingly, there is no consensus yet on solid pedagogical approaches for MOOCs. Something similar can be said for learning analytics, another upcoming concept that is receiving a lot of attention. Given its nature, learning analytics offers a large potential to support learners in particular in MOOCs. Learning analytics should then be applied to assist the learners and teachers in understanding the learning process and could predict learning, provide opportunities for pro-active feedback, but should also results in interventions aimed at improving progress. This paper illustrates pedagogical and learning analytics approaches based on practices developed in formal online and distance teaching university education that have been fine-tuned for MOOCs and have been piloted in the context of the EU-funded MOOC projects ECO (Elearning, Communication, Open-Data: http://ecolearning.eu) and EMMA (European Multiple MOOC Aggregator: http://platform.europeanmoocs.eu).

Of two contrasting philosophies that underpin openness in education and what that entails

From the conclusion: The ultimate question is a normative one: Which way do we want that openness in education to go? That question concerns educational resources, open educational practices and what other forms the educational system may spawn. For ultimately, we as stakeholders, in the learning of our children and grandchildren, in the professional development and Bildung of ourselves, should get the educational systems that we want, including appropriate forms of openness therein. Every individual then should decide for herself or himself to what extent this requires education as a public good and to what extent education as a private good, that is, as a commodity subject to market forces. It should not come as a surprise that we side with the humanitarian elaboration of openness. Indeed, we feel that governments as guardians of the public space should actively get involved in promoting this kind of openness, indeed, much as Delors in 1996 advocated for education as a whole.
