Development, implementation, and evaluation of an online English placement test at college level: a case study.

The primary purpose of the present project was to research the case study of current English placement practices at Intercollege in view of incorporating change, improvement and efficiency, within the framework of current work based learning and applied linguistics (and more particularly English online language testing) research discipline. The review of work based learning and current theories and practices in applied linguistics research discipline helped establish the characteristics of an insider researcher and the research approach and research techniques that would best serve such a project. The review of current theories and practices in second language (L2) teaching and learning in general, and in L2 testing in particular revealed that there is an extensive range of practices: these range from testing discrete points to integrative tasks. Tests are also delivered both in pen-and-paper as well as in electronic form, the latter being either computer based testing (CBT) or computer adaptive testing (CAT). The review of current English placement practices at Intercollege indicated the need for a new English placement test, developed in a scientific way, informed by current theories and practices, based on current test design models and taking advantage of more efficient methods of delivery, and placement. This review also revealed the need for more efficiency in the mode of delivery, administration, marking, reporting and test duration. Finally, this study of the current English placement practices at Intercollege established the need for a placement test that would incorporate a mechanism of continuous testing of reliability and validity as well as improvement. The detailed study of the specific context, setting, particular language programme, resources, test-takers, instructors, etc. informed by current theories and practices in second language (L2) testing online, helped in the development of the New English Placement Test Online (NEPTON) test specifications, and as a consequence, the development of the proposed test itself. The study of test delivery modes and the consideration of the specific work based conditions and requirements. For example administration, delivery, time and money efficiency, urgent need of an improved and more efficient English placement test (EPT) resulted in the selection of computer based testing delivery, with many features of the computer adaptive testing delivery mode incorporated in it such as randomized selection of test items and fewer items. The test item writing and item modération process resulted in the formation of a substantial pool of varied items in different skills, text types, topics, settings, and covering a variety of lexical and grammatical points and communicative, authentic-like situations in ali six levels. The field test which was took place in May 2004 in pen-and-paper form by almost 1200 students in ali three Intercollege campuses helped check the content and the test trial which took place in the period of August-September in its electronic form helped come up with the test cutoff points, and the fine-tuning of the test. The item analysis ensured the appropriateness of ali items. Pre-test questionnaires established test-takers' biographical data and information about test-taker computer familiarity. The test face validity (stakeholders' attitudes and feelings about the NEPTON) was established through the use of pre and post-test questionnaires. Experts in the area Coming, from the three campuses, also studied the test specifications and the test itself (both in its electronic and pen-and-paper format) and completed a questionnaire, thus contributing to the establishment of the test content and construct validity. The test reliability was established through a split half reliability index process and a series of other aspects or processes such as the size of the item bank, the instructions, the moderation process, and the item analysis, which are explained in chapter 5 in more details. The research project consists of two components: (a) The report, which describes the way work based and applied linguistics research approaches were used to investigate the case study of English placement test at college level at Intercollege in Cyprus and to what extent this has broad change, improvement and effìciency to current practices; and (b) The evidence of such a research project, which is the New English Placement Test Online (NEPTON), in other words, the test itself, developed, implemented and evaluated in order to materialize this change, improvement and efficiency aimed at by this project

The Impact of the Internationalisation of Higher Education on Scientists’ Multimodal Communication: A case study from Catalonia

Les universitats de tot el món són instades a participar en el procés d' ‘internacionalització’ com a distintiu de qualitat i com a reclam per atraure estudiants. Aquest estudi aborda aquesta qüestió des del context de les institucions catalanes d’educació superior, que afronten el dilema de donar suport a la/les llengua/gües local/s i, alhora, abraçar el multilingüisme i, sobretot, l’anglès. L'objectiu principal d'aquest estudi és examinar l'impacte de la internacionalització de l'educació superior en la comunicació diària dels científics. Les dades etnogràfiques s’han recopilat al llarg d’un període d’11 mesos d’observació de dos grups de recerca (RGs) multinacionals amb seu en una universitat catalana, i s’han contrastat amb dades extretes d’un RG amb seu a Alemanya i amb idees inspirades en les pràctiques del RG de la pròpia investigadora. De l'objectiu empíric n’ha derivat un objectiu teòric, que consisteix a dissenyar i provar un marc teòric adequat per estudiar el fenomen proposat de manera integral. Aquest estudi té l’objectiu de contribuir a la limitada literatura que descriu aquelles pràctiques comunicatives "informals" i inèdites dels científics, així com a la literatura sobre la internacionalització de l’ensenyament superior. A nivell pràctic, aquest treball pretén contribuir a la millora de les polítiques d’internacionalització de les institucions d’ensenyament superior de Catalunya, d’Europa i potencialment d’altres contextos arreu del món.Las universidades de todo el mundo son instadas a participar en el proceso de ‘internacionalización’ como distintivo de calidad y como reclamo para atraer estudiantes.

The current study approaches this issue from the context of Catalan higher education institutions, which deal with the dilemma of supporting the local language(s) and at the same time embracing multilingualism and especially English. The main aim of this study is to examine the impact of the internationalisation of higher education on the daily communication of scientists. Ethnographic data have been collected throughout a period of 11 months from two multinational research groups (RGs) based in a Catalan state university, and contrasted with data taken from a RG based in Germany and with insights from the researcher’s own RG. From the empirical objective has derived a theoretical objective, consisting in designing and proving a suitable theoretical framework to study the phenomenon holistically. This study aims to contribute to the limited body of research describing scientists’ "informal" and unpublished communicative practices, as well as to the literature on the internationalisation of higher education. On a practical level, this work is intended to aid in the improvement of internationalisation policies of higher education institutions in Catalonia, in Europe and potentially in other contexts worldwide

Explorations of knowledge management in a defence engineering environment

This thesis originates from first hand early experiences of the researcher regarding current processes and practices in operation in BAE SYSTEMS Ltd (now referred to hereafter as `the Company'), and recognises the potential for improvement within the realm of knowledge management. The huge volume of internal and external information overwhelms the majority of organisations and knowledge management provides solutions to enable organisations to be effective, efficient, and competitive. The software agent approach and information retrieval technique indicates great potential for effectively managing information. This research seeks to answer the questions of whether software agents can provide the Company with solutions to the knowledge management issues identified in this inquiry and whether they can also be used elsewhere within the organisation to improve other aspects of the business. The research analysis shows that software agents offer a wide applicability across the Company; can be created with relative ease and can provide benefits by improving the effectiveness and efficiency of processes. Findings also provided valuable insight into human-computer-interface design and usability aspects of software agent applications. The research deals with these questions using action research in order to develop a collaborative change mechanism within the Company and a practical applicability of the research findings in situ. Using a pluralistic methodology the findings provide a combination of the subjective and objective views intermittently within the research cycles thereby giving the researchera more holistic view of this research. Little attention has been paid to integrating software agent technologies into the knowledge management processes.This research proposes a software agent application that incorporates: (1) Co-ordination of software agents for information retrieval to manage information gathering, filtering, and dissemination; (2) To promote effective interpretation of information and more efficient processes;(3) Building accurate search profiles weighted on pre-defined criteria; (4) Integrating and organising a Company resource management knowledge-base; (5) Ensuring that the right information gets to the right personnel at the right time; and (6) So the Company can effectively assign the right experts to the right roles within the Company

The design of speech-based automated mobile phone services using interface metaphors

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Interface metaphor is a widely used design technique for interactive computer systems. The advantages of using interface metaphors derive from their ability to promote active learning, which enables a user to transfer knowledge from a familiar real world domain, to an unfamiliar computing domain. Interface metaphor is not currently used for the design of automated phone services, and it was the aim of this thesis to examine whether interface metaphor could improve the usability of speech-activated automated mobile phone services. A human-centred design methodology was followed to generate, select, and develop potential metaphors, which were used to implement metaphor-based phone services. An experimental methodology was then used to compare the usability of the metaphor-based services with the usability of currently available number-based phone services. The first experiment examined the effect of three different interface metaphors on the usability of a mobile city guide service. Usability was measured as a range of performance and attitude measures, and was supplemented by telephone interview data. After three consecutive days of usage, participants both preferred, and performed better with, the service that was based on an office filing system metaphor. Experiment two was conducted over a six week period, and investigated the effect of users' individual differences, and the context of use, on the usability of both the office filing system metaphor-based service, and a non-metaphor service. The results showed that performance with the metaphor-based service was significantly better than performance with the non-metaphor service. The usability of the metaphor-based service was not significantly affected by users' individual characteristics and aptitudes, whereas the number-based service was, suggesting that metaphor-based services may be more usable for a wider range of potential users. Usability levels for both services were found to be consistent across both private and public locations of use, suggesting that speech-activated mobile phone services provide a flexible means of information access. Experiment three investigated the strategies used by participants when interacting with mobile phone services, specifically the visualisation strategy that was used by two thirds of the metaphor-based service participants in experiment two. In addition to the attitude and performance measures used for experiments one and two, face-to face interviews were conducted with participants. The results indicated that significantly more participants visualised the metaphor-based services relative to a non-metaphor service, and that visualisation of the service structure led to significant performance improvements. This thesis has demonstrated the usability benefits of interface metaphor as a design technique for speech-based mobile phone services. These benefits of metaphor appear to derive from their ability to provide a mental model of the phone service that can be visualised, and their ability to accommodate the individual differences of users

Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm

Abstract— Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can’t store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system. Keywords— Shortest Path, Algorithm Dijkstra, Node Combination, Dynamic Location (key words

Behavioral, educational, and methodological perspectives on multicultural team learning processes

Thesis (S.M.)--Massachusetts Institute of Technology, Sloan School of Management, 2008.Includes bibliographical references (p. 171-192).This study starts from the notion that leadership is about mobilizing learning, and simultaneously pursues multifaceted purposes that benefit from each other: 1) to shed new light on learning behaviors of teams facing unfamiliarity, 2) develop one model of practical and effective leadership education, and 3) apply new technology to make methodological contributions to organizational studies, leadership education, and management practices. 1) The central research question is what behavioral factors affect team learning when the team faces both internal and external unfamiliarity - which stems from diversity and cultural barriers, and disruptive threats from the environment. The study examines 6 multicultural teams undergoing increasingly complex tasks, revealing the structures and processes with which they self-organized and temporal responses to the difficulties. 2) The experimental setting was a 10-days intensive leadership workshop with a distinct educational purpose to raise the participants' levels of contextual, reflective, and moral awareness, with the premise that exercising leadership involves mobilizing learning to adapt to unfamiliarity. The study attempts to assess the effectiveness of the workshop, while examining the effects of exercise of leadership on the teams' learning processes. 3) The study also applies wearable sensors that capture nonlinguistic social signals and visualize group interaction patterns, for 3 intended applications as (a) research tool for social network analysis to supplement ethnography, (b) learning tool to stimulate reflection and dialogue, and (c) intervention tool to alter the flows of information.(cont.) The study identified 3 team learning strategies: inoculation (face internal difficulties earlier and get prepared for an external threat), time out (stop actions when facing a threat and use it to re-orient team's attention to internal difficulties), and structure it away (develop an internal structure that eliminates the internal difficulties). The conditions for team learning and personal development, appropriate challenge and support, resulted from exercise of leadership that emerged from complex interactions among the team members and the facilitators. Commonly observed signs of such conditions included surfacing and facing conflicts, revealing vulnerabilities, accommodating emotional breakdowns, and sense of mutual respect based on demonstrated acceptance. The study indicates that use of sensors contributed to formation of the team learning condition.by Naoto Kanehira.S.M

Validation of design artefacts for blockchain-enabled precision healthcare as a service.

Healthcare systems around the globe are currently experiencing a rapid wave of digital disruption. Current research in applying emerging technologies such as Big Data (BD), Artificial Intelligence (AI), Machine Learning (ML), Deep Learning (DL), Augmented Reality (AR), Virtual Reality (VR), Digital Twin (DT), Wearable Sensor (WS), Blockchain (BC) and Smart Contracts (SC) in contact tracing, tracking, drug discovery, care support and delivery, vaccine distribution, management, and delivery. These disruptive innovations have made it feasible for the healthcare industry to provide personalised digital health solutions and services to the people and ensure sustainability in healthcare. Precision Healthcare (PHC) is a new inclusion in digital healthcare that can support personalised needs. It focuses on supporting and providing precise healthcare delivery. Despite such potential, recent studies show that PHC is ineffectual due to the lower patient adoption in the system. Anecdotal evidence shows that people are refraining from adopting PHC due to distrust. This thesis presents a BC-enabled PHC ecosystem that addresses ongoing issues and challenges regarding low opt-in. The designed ecosystem also incorporates emerging information technologies that are potential to address the need for user-centricity, data privacy and security, accountability, transparency, interoperability, and scalability for a sustainable PHC ecosystem. The research adopts Soft System Methodology (SSM) to construct and validate the design artefact and sub-artefacts of the proposed PHC ecosystem that addresses the low opt-in problem. Following a comprehensive view of the scholarly literature, which resulted in a draft set of design principles and rules, eighteen design refinement interviews were conducted to develop the artefact and sub-artefacts for design specifications. The artefact and sub-artefacts were validated through a design validation workshop, where the designed ecosystem was presented to a Delphi panel of twenty-two health industry actors. The key research finding was that there is a need for data-driven, secure, transparent, scalable, individualised healthcare services to achieve sustainability in healthcare. It includes explainable AI, data standards for biosensor devices, affordable BC solutions for storage, privacy and security policy, interoperability, and usercentricity, which prompts further research and industry application. The proposed ecosystem is potentially effective in growing trust, influencing patients in active engagement with real-world implementation, and contributing to sustainability in healthcare
