Use and useability of learning objects within the COLIS demonstrator framework (Interaction of IT systems & repositories project report)
No full text[Executive Summary]: Murdoch University was one of several institutions and consortia funded to investigate the educational use of the Collaborative Online Learning and Information Services (COLIS) system developed in 2002 by a consortium based at Macquarie University. This project set out to investigate the use and useability of learning objects across three aspects of the COLIS system. Existing, single file learning objects were to be inserted into the IPR Systems Learning Object Exchange (LOX), transferred into the Learning Object Management System (LOMS), and made available through the WebCT Learning Management System. With the forced substitution of the Intralibrary Learning Object Repository for the IPR Systems exchange, the use of LOMS became superfluous. Similarly, the Federated search gateway did not function with the Intralibrary Learning Object Repository. Instead, Intralibrary’s own search function was used
The initial stages of development of the Carrick exchange
No full textThe development of the Carrick Exchange is a major initiative of the Carrick Institute for Learning and Teaching in Higher Education. The Carrick Exchange will combine a learning and teaching repository function with a Web 2.0 social networking capability 13 a MySpace for academics. It is aimed at those who teach, manage and lead in Higher Education in Australia. This paper reports on the initial stages of development. In particular, imaginary scenarios were used to envision the nature and the scope of the project. This work led to the identification of numerous human and technical issues which need to be addressed for the Carrick Exchange to be sustainable
Retrieval through explanation : an abductive inference approach to relevance feedback
No full textRelevance feedback techniques are designed to automatically improve a system's representation of a query by using documents the user has marked as relevant. However, traditional relevance feedback models suffer from a number of limitations that restrict their potential in supporting information seeking. One of the major limitations of relevance feedback is that it does not incorporate behavioural aspects of information seeking - how and why users assess relevance. We propose that relevance feedback should be viewed as a process of explanation and demonstrate how this limitation of relevance feedback techniques can be overcome by a theory of relevance feedback based on abductive inference
Use and usability of learning objects within the COLIS demonstrator framework
No full textMurdoch University was one of several institutions and consortia funded to investigate the educational use of the Collaborative Online Learning and Information Services (COLIS) system developed in 2002 by a consortium based at Macquarie University. This project set out to investigate the use and usability of learning objects across three aspects of the COLIS system. The major focus of this research was on the experience of the teacher in using learning objects within the COLIS framework.
Several activities took place. Librarians catalogued learning objects into the intraLibrary Learning Object Repository. Academic teaching staff searched for learning objects in intraLibrary and inserted them into WebCT. We investigated how easy it was for these stakeholders to use the suite of systems and identified ways in which both the systems and the processes around the systems might be improved
Magnetic tunnel junctions with yttrium oxide barrier
No full textMagnetic tunnel junctions have been studied, with YOx barriers prepared by plasma oxidation of a 1.5 nm Y film. We report their junction area resistance, tunnel magnetoresistance (TMR) and barrier parameters (height and thickness) as a function of the oxidation time. For the optimum oxidation time, TMR values of similar to25% are obtained at room temperature and similar to44% at low temperature (5 K). The barrier height extracted from the current-voltage curves, is close to 1 eV, which is less than half of what is usually reported for AlOx-based junctions. Structural and topographical characterization of the multilayes revealed that the YOx layer is amorphous with well-defined, smooth, and correlated interfaces with the ferromagnetic electrodes.

Librarian’s Attitude Towards Information Communication Technology in Colleges Affiliated to Sant Gadge Baba Amravati University: A Study
No full textNow a day’s libraries have deployed the ICT facilities, along with high speed internet connectivity,photo- copiers, and soft copy drop facilities via USB drives, DVD R-W, micro SD drives, fax,scanners and computers. When all such facilities are backed by Government aids, the support of a
trained librarian having good orientation and attitude is very important. The organizational and infrastructural facilities and the service of library professionals are to go hand in hand to fully utilize ICT. The research findings reveal that lack of awareness and psychological barriers against advance technologies are the hurdles in providing ICT based LIS services
Tunnel junctions with yttrium oxide barrier and various ferromagnetic electrodes
No full textThis work concerns tunnel junctions with yttrium oxide barrier prepared by plasma oxidation of a 1.5-nm Y film. The magnetoresistive properties of the junctions were studied as a function of the ferromagnetic (FM) electrodes in contact with the barrier, such as CoFe, Py (permalloy), and CoFeNiSiB. The maximum measured tunnel magnetoresistance (TMR) effect was 25% at room temperature-raised to over 40 % at 5 K. The TMR and the tunnel barrier characteristics (thickness, height, and asymmetry) depend significantly on the FM electrodes and the annealing temperature. Barrier heights of less than 1 eV have been extracted in all cases -two to three times lower than the ones reported for AlOx-based junctions

Previous issue date: 2016-12-15Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPESThe object of analysis of this scientific research is the problem of the collision of duties in
criminal law and the main purpose was to investigate the legal-penal treatment given to such
cases. The methodology consists n the bibliographic review and analysis of legal precedents
related to the thematic, with the analysis of the proposals of resolution to the problem. The
present work is structured in three chapters. In the first chapter, it seeks to recover the
dogmatic, legislative and jurisprudential antecedents of five countries (Germany, Italy, Spain,
Portugal and Brazil). On the other hand, in the second chapter analyses the main proposals of
resolution of collision of duties, which were gathered in nine groups (causes of reduction of
the penalty, exclusion of the penalty, exclusion of mens rea, abstaining from the judgment of
guilt, exclusion from the responsibility of the fact, justification, theory of free space of law
and cause of exclusion of actus reus), analyzing the merits and demerits of each theoretical
construction. In the third and final chapter there is the taking of a position on the subject, in
which it is concluded that the collision of duties, despite having few similarities with the
necessity, has its application restricted to collisions between duties of action, having its own a foundation and legal consequences, and it is the sole cause of justification in cases involving innocent lives.O objeto de an?lise da presente pesquisa cient?fica consiste na problem?tica da colis?o de
deveres em direito penal e o objetivo estabelecido foi o de investigar o tratamento jur?dicopenal
conferido a tais situa??es. Consiste a metodologia utilizada na revis?o bibliogr?fica e
an?lise de precedentes relacionados ? tem?tica, com a an?lise das propostas de resolu??o do
problema. O presente trabalho est? estruturado em tr?s cap?tulos. No primeiro cap?tulo buscase
resgatar os antecedentes dogm?ticos, legislativos e jurisprudenciais de cinco pa?ses
(Alemanha, It?lia, Espanha, Portugal e Brasil). No segundo cap?tulo ocorre a an?lise das
principais propostas de resolu??o de colis?o de deveres, as quais foram reunidas em nove
grupos (causas de diminui??o da pena, exclus?o da pena, exclus?o de culpabilidade, absten??o
do ju?zo da culpabilidade, exclus?o da responsabilidade do fato, exclus?o da ilicitude, teoria
do espa?o livre de direito e causa de exclus?o da tipicidade), analisando os m?ritos e
dem?ritos de cada constru??o te?rica. No terceiro e ?ltimo cap?tulo ocorre a tomada de
posi??o sobre o tema, no qual se conclui que a colis?o de deveres, apesar de possuir pontos de
encontro com o estado de necessidade, tem sua aplica??o restrita ?s colis?es entre deveres de
a??o, possuindo fundamento e consequ?ncias jur?dicas pr?prias, sendo a ?nica causa de
exclus?o da ilicitude em casos que envolvem vidas inocentes
