Certified pseudonyms colligated with master secret key

A pseudonym provides anonymity by protecting the identity of a legitimate user. A user with a pseudonym can interact with an unknown entity and be confident that his/her identity is secret even if the other entity is dishonest. In this work, we present a system that allows users to create pseudonyms from a trusted master public-secret key pair. The proposed system is based on the intractability of factoring and finding square roots of a quadratic residue modulo a composite number, where the composite number is a product of two large primes. Our proposal is different from previously published pseudonym systems, as in addition to standard notion of protecting privacy of an user, our system offers colligation between seemingly independent pseudonyms. This new property when combined with a trusted platform that stores a master secret key is extremely beneficial to an user as it offers a convenient way to generate a large number of pseudonyms using relatively small storage.

Model studies toward the total synthesis of thebaine by an intramolecular cycloaddition strategy

The present studies describe recent progress toward the synthesis of the thebaine. Model substrates were synthesized using pyridazine derivatives as a starting material, which allowed to assess the key Diels-Alder reaction as a route to construct the thebaine core.

Towards a cyberspatial pedagogy : exploring synchronous online learning potentials

It has been a quarter of a century since William Gibson (1984) coined the term cyberspace in his seminal science fiction novel Neuromancer. Subsequently, a proliferation of online teaching technologies have emerged supporting Virilio’s (1991) contention that, “time and space have ceased to function as meaningful dimensions to human thought and action.” The aim of this presentation is to discuss and demonstrate the innovative modification of an online, synchronous learning environment, Elluminate Live! (eLive), which allows participants to transcend the spatial dimension. Specifically, we present an example of good practice which aimed to enhance student engagement by implementing a structured online tutorial series which replicated the entire first year psychology on-campus tutorial series in the eLive environment. We discuss Student Evaluation of Teaching and Units (SETU) results which support the utility of this pedagogic strategy. Finally, we outline various challenges for the virtual teacher who wishes to implement a structured learning program in the eLive environment.

The effect of the introduction of teaching interventions and assessment strategies in first year management units

This Scholarship of Teaching research aimed to ultimately become a report and a series of recommendations on the teaching of first year Management units in universities. Many of the Australian universities benchmark themselves against the leaders in the Course Experience Questionnaires (CEQ) (Ramsden 1991) of graduating students in Australia. Most Australian universities have their own student satisfaction evaluation method. In this study the subject university uses the Student Evaluation of Teachers and Units (SETU) as their internal method of measuring the effectiveness of teaching on units on a cohort by cohort basis. This project, using one of the largest units in a Business and Law Faculty had specific measurable objectives; the results of the unit teams' interventions demonstrate that it is possible to increase student satisfaction during their transition year by as much as 11.5%. The ten recommendations ranging from changes to unit objectives, assessment methods and updated methods of marking, communication and student support, if acted upon, should have ongoing benefits for teaching and learning of first year management units.

Student evaluation of teaching data 2009-2010

This dataset consists of a summary of publicly available student evaluation of teaching (SET) data for the annual period of trimester 2 2009, trimester 3 2009/2010 and trimester 1 2010, from the Student Evaluation of Teaching and Units (SETU) portal.

The data was analysed to include mean rating sets for 1432 units of study, and represented 74498 sets of SETU ratings, 188391 individual student enrolements and 58.5 percent of all units listed in the Deakin University handbook for the period under consideration, to identify any systematic influences on SET results at Deakin University.

The data reported for a unit included:
• total enrolment;
• total number of responses; and
• computed response rate for the enrolment location(s) selected

And, the data reported for each of the ten core SETU items included:
• number of responses;
• mean rating;
• standard deviation of the mean rating;
• percentage agreement;
• percentage disagreement; and
• percentage difference.

Challenging student satisfaction through the education of desires

This article challenges the practice of encouraging teacher educators to strive and raise the levels of student satisfaction in their classes as if such a criterion provides a measure of good teaching. Such a practice involves what Giroux describes as ‘corporate pedagogy’ which conforms to the neoliberal inclination to meet the demands of the customer in the market. However it is argued in this paper that educative teaching, as especially described by Dewey, ought to challenge and re-evaluate the expectations and desires that students bring with them to class. Rather than aiming to satisfy customer expectations, teacher educators ought to lead the tertiary sector by challenging the notion of good quality teaching through educating the desires of students. Perhaps this may involve educators aiming to ‘dissatisfy’ students as per Mill’s ‘dissatisfied Socrates’.

The systematic influences on student evaluation of teaching in engineering education

BACKGROUND Student evaluation of teaching (SET) has a long history, has grown in prevalence and importance over a period of decades, and is now common-place in many universities internationally. SET data are collected for a range of purposes, including: as diagnostic feedback to improve the quality of teaching and learning; as an input to staff performance management processes and personnel decisions such as promotion for staff; to provide information to prospective students in their selection of courses and programs; and as a source of data for research on teaching. Rovai et al. (2006) report that while SET research provides mixed results, there is evidence that, for course-related factors, smaller classes are rated more favourably than large classes, upper-year-level classes are rated more favourably than lower-year classes, and that there are rating differences between discipline areas. While additional course-related factors are also noted, other reviews of the literature on SET also identify these three factors as commonly reported systematic influences on SET ratings. The School of Engineering at Deakin University in Australia offers undergraduate and postgraduate engineering programs, and these programs are delivered in both on-campus and off-campus modes.PURPOSEThe paper presents a quantitative investigation of SET data for the School of Engineering at Deakin University to identify whether the commonly reported systematic influences on SET ratings of class size and year level are also observed here. The influence of online mode of offer is also explored.DESIGN/METHOD Deakin University’s Student Evaluation of Teaching and Units (SETU) questionnaire is administered to students enrolled in every unit of study every time that unit is offered, unless it is specially exempted. Following data collation, summary results are reported via a public website. The publicly available SETU data for all School of Engineering units of study were collected for a two year period. The collected data were subjected to analysis of variance (ANOVA) analysis to identify any significant systematic influences on mean student SETU ratings.RESULTS SETU data from 100 separate units of study over the two year period were collected, representing 3375 sets of SETU ratings, and covering unit enrolment sizes from 12 to 462 students. Although this was a modest sized investigation, significantly higher mean ratings for some SETU items were observed for units with small enrolments, for postgraduate level units compared to undergraduate level units, and for units offered in conventional mode compared to online mode of offer. The presence of the commonly observed systematic influences on SET ratings was confirmed.CONCLUSIONS While the use of SET data may have originally been primarily for formative purposes to improve teaching and learning, they are also increasingly used for summative judgements of teaching quality and teaching staff performance that have implications for personnel decision making. There may be an acceptance of the need for SET, however there remains no universal consensus as to what constitutes quality in university teaching and learning, and the increasing use of SET for high-stakes decision making puts pressure on institutions to ensure that their SET practices are sound, equitable and defensible.

Using video to promote pre-service teachers’ thinking about their transition to teaching

This paper reports on research investigating the use of video representations of first-year teachers’ experiences in undergraduate teacher education workshops that focus on the transition to teaching. The use of the video is a responsive act that draws on the notion of looking back, where graduates in their first year of teaching ‘speak to’ current students. Scenes from video footage of the theatre-based research performance The First Time shaped workshop activities and discussions in the unit. Themes ranged from pedagogical to practical, covering topics such as teacher identity discourses; epiphanic and revelatory moments of transition to becoming a teacher; and preparing for job applications and interviews. Data from the researcher’s journal, Student Evaluation of Teaching and Units (SETU) comments, and semi-structured interviews with undergraduate students upon completion of the workshops are framed within a phenomenographic paradigm. The aim in phenomenography is to describe variations of conception that people have of a particular phenomenon (Sin, 2010), in this case the video as a tool to promote critical thinking about the transition to teaching. The researcher explored her own, and participants’ experiences, and identified a range of conceptual meanings of the phenomenon. These were classified into categories according to their similarities and differences concerning the effectiveness of this specific video in assisting undergraduates in their transition to teaching. Early results reveal some similarities and many variations among participants as to the effectiveness of the video as a tool. Their conceptions of the phenomenon are individual and relational, and as such are quite varied. Emergent varied themes include: ‘I know what it is that I need to learn’; ‘Is this theory or practice?’; and ‘I don’t do drama’. Emergent similarities include: ‘Preparing for the unexpected’.

O PROCESSO DE REGIONALIZAÇÃO DO TURISMO NO SUDOESTE DO PARANÁ – BRASIL

O texto apresenta resultados de uma pesquisa que buscou analisar a trajetória histórica e o desenvolvimento do processo de Regionalização do Turismo no Sudoeste do Paraná, tendo como base as políticas públicas do governo federal (Brasil) e do estado do Paraná relacionadas à Regionalização do Turismo, bem como as ações da Governança criada para gerenciar esse processo. O foco principal da pesquisa foi a Região Turística do Sudoeste, uma das 10 regiões turísticas do Paraná conforme classificação da SETU (Secretaria de Estado do Turismo do Paraná). A partir do Macroprograma de Regionalização do Turismo, implantado pelo Governo Federal junto ao MTur (Ministério do Turismo), a SETU foi a instituição responsável por organizar as regiões turísticas do Paraná. Inicialmente, trabalhamos com os documentos e diretrizes do MTur sobre a Regionalização do Turismo, com o intuito de verificar quais os objetivos e a metodologia proposta a nível federal. Analisamos os documentos referentes à Regionalização do Turismo no Paraná, considerando os objetivos, a metodologia e as regiões turísticas definidas. Finalmente, focamos a pesquisa na Região Turística Sudoeste-PR, denominada “Vales do Iguaçu”, onde verificamos como se deu a implantação da Governança Regional do Turismo no Sudoeste, considerando as instituições envolvidas e as ações realizadas.
