Research and teaching: a holy or an unholy alliance?

Much of the self-image of the Western university hangs on the idea that research and teaching are intimately connected. The central axiom here is that research and teaching are mutually supportive of each other. An institution lacking such a set of relationships between research and teaching falls short of what it means to be a university. This set of beliefs raises certain questions: Is it the case that the presence of such a mutually supportive set of relationships between research and teaching is a necessary condition of the fulfilment of the idea of the university? (A conceptual question). And is it true that, in practice today, such a mutually supportive set of relationships between research and teaching characterises universities? (An empirical question). In my talk, I want to explore these matters in a critical vein. I shall suggest that: a) In practice today, such a mutually supportive set of relationships between research and teaching is in jeopardy. Far from supporting each other, very often research and teaching contend against each other. Research and teaching are becoming two separate ideologies, with their own interest structures. b) Historically, the supposed tight link between research and teaching is both of recent origin and far from universally achieved in universities. Institutional separateness between research and teaching is and has been evident, both across institutions and even across departments in the same institution. c) Conceptually, research and teaching are different activities: each is complex and neither is reducible to the other. In theory, therefore, research and teaching may be said to constitute a holy alliance but in practice, we see more of an unholy alliance. If, then, in an ideal world, a positive relationship between research and teaching is still a worthwhile goal, how might it be construed and worked for? Seeing research and teaching as two discrete and unified sets of activity is now inadequate. Much better is a construal of research and teaching as themselves complexes, as intermingling pools of activity helping to form the liquid university that is emerging today. On this view, research and teaching are fluid spaces, ever on the move, taking up new shapes, and themselves dividing and reforming, as the university reworks its own destiny in modern society. On such a perspective, working out a productive relationship between research and teaching is a complex project. This is an alliance that is neither holy nor unholy. It is an uneasy alliance, with temporary accommodations and continuous new possibilities

The value of using short-format podcasts to enhance learning and teaching

This paper presents the findings of a podcasting trial held in 2007-2008 within the Faculty of Economics and Business at the University of Sydney, Australia. The trial investigates the value of using short-format podcasts to support assessment for postgraduate and undergraduate students. A multi-method approach is taken in investigating perceptions of the benefits of podcasting, incorporating surveys, focus groups and interviews. The results show that a majority of students believe they gained learning benefits from the podcasts and appreciated the flexibility of the medium to support their learning, and the lecturers felt the innovation helped diversify their pedagogical approach and support a diverse student population. Three primary conclusions are presented: (1) most students reject the mobile potential of podcasting in favour of their traditional study space at home; (2) what students and lecturers value about this podcasting design overlap; (3) the assessment-focussed, short-format podcast design may be considered a successful podcasting model. The paper finishes by identifying areas for future research on the effective use of podcasting in learning and teaching.

Enhanced convolution approach for CAC in ATM networks, an analytical study and implementation

The characteristics of service independence and flexibility of ATM networks make the control problems of such networks very critical. One of the main challenges in ATM networks is to design traffic control mechanisms that enable both economically efficient use of the network resources and desired quality of service to higher layer applications. Window flow control mechanisms of traditional packet switched networks are not well suited to real time services, at the speeds envisaged for the future networks. In this work, the utilisation of the Probability of Congestion (PC) as a bandwidth decision parameter is presented. The validity of PC utilisation is compared with QOS parameters in buffer-less environments when only the cell loss ratio (CLR) parameter is relevant. The convolution algorithm is a good solution for CAC in ATM networks with small buffers. If the source characteristics are known, the actual CLR can be very well estimated. Furthermore, this estimation is always conservative, allowing the retention of the network performance guarantees. Several experiments have been carried out and investigated to explain the deviation between the proposed method and the simulation. Time parameters for burst length and different buffer sizes have been considered. Experiments to confine the limits of the burst length with respect to the buffer size conclude that a minimum buffer size is necessary to achieve adequate cell contention. Note that propagation delay is a no dismiss limit for long distance and interactive communications, then small buffer must be used in order to minimise delay. Under previous premises, the convolution approach is the most accurate method used in bandwidth allocation. This method gives enough accuracy in both homogeneous and heterogeneous networks. But, the convolution approach has a considerable computation cost and a high number of accumulated calculations. To overcome this drawbacks, a new method of evaluation is analysed: the Enhanced Convolution Approach (ECA). In ECA, traffic is grouped in classes of identical parameters. By using the multinomial distribution function instead of the formula-based convolution, a partial state corresponding to each class of traffic is obtained. Finally, the global state probabilities are evaluated by multi-convolution of the partial results. This method avoids accumulated calculations and saves storage requirements, specially in complex scenarios. Sorting is the dominant factor for the formula-based convolution, whereas cost evaluation is the dominant factor for the enhanced convolution. A set of cut-off mechanisms are introduced to reduce the complexity of the ECA evaluation. The ECA also computes the CLR for each j-class of traffic (CLRj), an expression for the CLRj evaluation is also presented. We can conclude that by combining the ECA method with cut-off mechanisms, utilisation of ECA in real-time CAC environments as a single level scheme is always possible.

Retrieval of effective ice crystal size in the infrared: sensitivity study and global measurements from TIROS-N Operational Vertical Sounder

The difference between cirrus emissivities at 8 and 11 μm is sensitive to the mean effective ice crystal size of the cirrus cloud, De. By using single scattering properties of ice crystals shaped as planar polycrystals, diameters of up to about 70 μm can be retrieved, instead of up to 45 μm assuming spheres or hexagonal columns. The method described in this article is used for a global determination of mean effective ice crystal sizes of cirrus clouds from TOVS satellite observations. A sensitivity study of the De retrieval to uncertainties in hypotheses on ice crystal shape, size distributions, and temperature profiles, as well as in vertical and horizontal cloud heterogeneities shows that uncertainties can be as large as 30%. However, the TOVS data set is one of few data sets which provides global and long-term coverage. Having analyzed the years 1987–1991, it was found that measured effective ice crystal diameters De are stable from year to year. For 1990 a global median De of 53.5 μm was determined. Averages distinguishing ocean/land, season, and latitude lie between 23 μm in winter over Northern Hemisphere midlatitude land and 64 μm in the tropics. In general, larger Des are found in regions with higher atmospheric water vapor and for cirrus with a smaller effective emissivity.

THERMAL BEHAVIOR STUDY AND DECOMPOSITION KINETICS OF SALBUTAMOL UNDER ISOTHERMAL AND NON-ISOTHERMAL CONDITIONS

The thermal decomposition of salbutamol (beta(2) - selective adrenoreceptor) was studied using differential scanning calorimetry (DSC) and thermogravimetry/derivative thermogravimetry (TG/DTG). It was observed that the commercial sample showed a different thermal profile than the standard sample caused by the presence of excipients. These compounds increase the thermal stability of the drug. Moreover, higher activation energy was calculated for the pharmaceutical sample, which was estimated by isothermal and non-isothermal methods for the first stage of the thermal decomposition process. For isothermal experiments the average values were E(act) = 130 kJ mol(-1) (for standard sample) and E(act) = 252 kJ mol(-1) (for pharmaceutical sample) in a dynamic nitrogen atmosphere (50 mL min(-1)). For non-isothermal method, activation energy was obtained from the plot of log heating rates vs. 1/T in dynamic air atmosphere (50 mL min(-1)). The calculated values were E(act) = 134 kJ mol(-1) (for standard sample) and E(act) (=) 139 kJ mol(-1) (for pharmaceutical sample).

A review of strategic issues in using the internet for teaching and learning

In 1998 the author published a paper entitled ‘Current Issues and limitations in using the Internet for Teaching and Learning’ [1] that acknowledged the new educational possibilities provided by the Internet, while at the same time sought to identify the limitations and related issues of going on-line in education. As predicted, the passage of time and the advancement of technology have ameliorated many of the identified limitations, and, have brought new issues to the fore. This paper re-visits the area of important strategic issues in using the Internet for education, giving an overview of equity and access, infrastructure and costs, copyright and plagiarism, content development, libraries and on-line information access, and other strategic issues. As in the earlier paper, this paper draws on the experiences of the author in conventional and off-campus university teaching in engineering.

Authenticity in assessment : reflecting undergraduate study and professional practice

The literature suggests that assessment is a powerful tool for influencing student study habits. It is also recognized that there is a tension between traditional forms of assessment and newer forms of assessment that offer a more authentic representation of practice, but are more complex and expensive to administer. The international trend in undergraduate engineering course accreditation to move to demonstration of attainment of graduate attributes poses new challenges in assessment of learning. A case study based on integrating assessment practices across the year levels of an engineering management studies stream in an undergraduate course is presented. Key features of the assessment portfolio include: the use of assessment in the first year as a foundational tool to establish student study habits and skills; the evolution of assessment tasks by the fourth year to reflect the world of professional practice and to allow students to demonstrate their integration of knowledge and skills; the weighting of assessment tasks to indicate the value attached to particular tasks; the structured inclusion of group work; a concern for student and staff workloads; the recognition of student diversity, in particular the needs of off-campus and mature-age students; and the matching of assessment tasks to professional accreditation requirements.

Social justice and the study and practice of leadership in education : a feminist history

This historical sociology deconstructs the interrelationship between the theory and practice of the troublesome notions of leadership, social justice and feminism. First, it tracks marginalised groups' relationship to the field of educational administration and their claims upon the state. Mainstream approaches have been informed by theories, practices and politics that do not focus on the core educational work of teaching and learning, therefore sidelining social justice issues. Second, it maps feminist and critical theorists' alternative conceptualisations, for example, of democratic leadership, which dissolve artificial binaries between formal and informal leadership. Finally, it considers what this means for re-theorising leadership for social justice.

The right to own : internationalization of perspectives of plagiarism and the internet

Cultural diversity in tertiary classrooms is integral to the current university scene. Teachers must incorporate different methods of delivery and
assessment to cater for an increasingly international student population. This paper explores the notion of plagiarism from two perspectives: the law
and English as a Second Language (ESL) writing theory.

Studio - learning and teaching environment for multimedia

This paper is a case study of the introduction of a studio environment for the teaching of multimedia practice. This change is in the context of multimedia being placed within an information technology degree program, where the conventions and traditions of computer science prevail. The studio based teaching was accepted and now new studios are being built at the university and a research project is proposed with the Queensland University of Technology to explore further teaching and learning issues using studio
teaching methods.

Teaching Chinese, teaching in Chinese, and teaching the Chinese

This article examines specific issues encountered in various areas of Chinese teaching in Australia. These issues are linked to the spheres of language planning as acquisition and as recovery and language planning as retention (Lo Bianco, 10.1007/s10993-006-9042-3). Specifically relevant to Chinese in Australia is its current prominence in formally declared national language policy, its changing status over time and its similarities and differences with Chinese in the United States (Wang, 10.1007/s10993-006-9043-2). The internationalization of education, and its commodification, has in recent years led to a major expansion in the range of offerings in Chinese in Australia, now catering to growing, and in some institutions to numerically dominant, groupings of native speakers with radically different language and academic needs from the traditional clientele of tertiary and school Chinese programs.

Nursing educations and graduates : profiles for 2001 and projections for 2002

The present study was commissioned for the National Review of Nursing Education. This is the second of two national studies commissioned to map in detail nursing education programs and to profile and make future projections regarding graduates from undergraduate and postgraduate nursing education courses in Australia.

The first study was undertaken in 2001 by Deakin University School of Nursing under the auspices of the 2001 Evaluation Investigations Project titled "Nursing Education and Graduates: Profiles for 1999, and 2000 with projections for 2001". This project sought data on nursing education within Australia in order to improve the accuracy of nursing education databases and to strengthen the ability of DETYA to provide advice on workforce planning. Issues that arose from that project included differences in data sets for undergraduate nursing courses in Australia and the complex process of attempting to tease out and accurately quantify postgraduate specialty courses when a trend towards postgraduate generic courses was evident. Approximately 26% of postgraduate domestic student enrolment data were reported utilising a generic nursing course category.

The purpose of this study was, therefore, twofold. Firstly, this study validated and extended the existing database developed in the previous study mapping in detail the full range of undergraduate programs offered by tertiary education providers across Australia that lead to an initial qualification and entry into nursing practice.

New data about the following was sought:

* Undergraduate nursing degrees (both three-year and four-year courses);
* Double/combined nursing degrees;
* Courses offered by private universities;
* Four-year bachelor degrees that concurrently provide both initial nurse registration and preparation for specialty nursing practice;
* Courses that facilitate ‘fast-tracking’ of students for initial nurse registration with previous tertiary or nursing studies,
* Hours and configuration of clinical experience in undergraduate nursing courses.
