Curriculum change in testing times

In these new, testing times, we need a new controlled rapid approach to curriculum change. Judy Smeed and TerrI Bourke explain.

Models of collective cell spreading with variable cell aspect ratio : a motivation for degenerate diffusion models

Continuum diffusion models are often used to represent the collective motion of cell populations. Most previous studies have simply used linear diffusion to represent collective cell spreading, while others found that degenerate nonlinear diffusion provides a better match to experimental cell density profiles. In the cell modeling literature there is no guidance available with regard to which approach is more appropriate for representing the spreading of cell populations. Furthermore, there is no knowledge of particular experimental measurements that can be made to distinguish between situations where these two models are appropriate. Here we provide a link between individual-based and continuum models using a multi-scale approach in which we analyze the collective motion of a population of interacting agents in a generalized lattice-based exclusion process. For round agents that occupy a single lattice site, we find that the relevant continuum description of the system is a linear diffusion equation, whereas for elongated rod-shaped agents that occupy L adjacent lattice sites we find that the relevant continuum description is connected to the porous media equation (pme). The exponent in the nonlinear diffusivity function is related to the aspect ratio of the agents. Our work provides a physical connection between modeling collective cell spreading and the use of either the linear diffusion equation or the pme to represent cell density profiles. Results suggest that when using continuum models to represent cell population spreading, we should take care to account for variations in the cell aspect ratio because different aspect ratios lead to different continuum models.

American public journalism versus other international media models

Chapter 2 of 'International Journalism and Democracy' provides examples of what the author dubs "deliberative journalism". Following a definition of deliberative journalism in Chapter 1, the book's second chapter examines major models of deliberative journalism that are in operation around the world. These models include public journalism, citizen journalism, community and alternative media, development journalism and peace journalism. The author argues that when these new forms of journalism are practiced well, they extend people's ability to identify, express, understand and respond to politics and issues affecting their communities. However, the main models of deliberative journalism all have contentious elements. Many deliberative journalism practioners have been subjected to criticism for lack of objectivity and poor professional standards. Many of their activities have clearly been ill-conceived. The author also finds that neither professional nor citizen journalists have a strong understanding of what constitutes "good practice" in deliberative journalism. Furthermore, there is much debate as to whether the type of "citizen journalism" that is posted intermittently on Facebook, Twitter, blogs and other social media can even be defined as "journalism". The practice of deliberative journalism can potentially contribute to public deliberation, but it does not always do so in any immediate or obvious way. The author finds that even so, deliberative journalism indirectly strengthens the environments that support fertile deliberation and decision making. (See the Extended Abstract for further details.)

Curriculum alignment: Exploring student perception of learning achievement measures

The importance of constructively aligned curriculum is well understood in higher education. Based on the principles of constructive alignment, this research considers whether student perception of learning achievement measures can be used to gain insights into how course activities and pedagogy are assisting or hindering students in accomplishing course learning goals. Students in a Marketing Principles course were asked to complete a voluntary survey rating their own progress on the intended learning goals for the course. Student perceptions of learning achievement were correlated with actual student learning, as measured by grade, suggesting that student perceptions of learning achievement measures are suitable for higher educators. Student perception of learning achievement measures provide an alternate means to understand whether students are learning what was intended, which is particularly useful for educators faced with large classes and associated restrictions on assessment. Further, these measures enable educators to simultaneously gather evidence to document the impact of teaching innovations on student learning. Further implications for faculty and future research are offered.

Overcoming challenges to collaboration: Nurse educators’ experiences in curriculum change

This article describes challenges to effective collaboration encountered by nurse educators as they transformed a unit within a school of nursing in Taiwan. This study introduced collaborative action research as a vehicle for curriculum change. Although the team achieved positive outcomes in transforming a unit, the collaborative process was complex with four major challenges: meaning, time, work culture, and conflicting views. This article provides an overview of the study, and the major challenges posed by working together are expounded and illustrated with excerpts drawn from the study data. Possible reasons for the challenges, how these challenges were overcome, and facilitation of the collaborative process are discussed.

How do consumers react to physically larger models? Effects of model body size, weight control beliefs and product type on evaluations and body perceptions

The purpose of this article is to examine how a consumer’s weight control beliefs (WCB), a female advertising model’s body size (slim or large) and product type influence consumer evaluations and consumer body perceptions. The study uses an experiment of 371 consumers. The design of the experiment was a 2 (weight control belief: internal, external) X 2 (model size: larger sized, slim) X 2 (product type: weight controlling, non-weight controlling) between-participants factorial design. Results reveal two key contributions. First, larger sized models result in consumers feeling less pressure from society to be thin, viewing their actual shape as slimmer relative to viewing a slim model and wanting a thinner ideal body shape. Slim models result in the opposite effects. Second this research reveals a boundary condition for the extent to which endorser–product congruency theory can be generalized to endorsers of a larger body size. Results indicate that consumer WCB may be a useful variable to consider when marketers consider the use of larger models in advertising.

International journalism and democracy : civic engagement models from around the world

"International Journalism and Democracy" explores a new form of journalism that has been dubbed ‘deliberative journalism’. As the name suggests, these forms of journalism support deliberation — the processes in which citizens recognize and discuss the issues that affect their communities, appraise the potential responses to those issues, and make decisions about whether and how to take action. Authors from across the globe identify the types of journalism that assist deliberative politics in different cultural and political contexts. Case studies from 15 nations spotlight different approaches to deliberative journalism, including strategies that have been sometimes been labeled as public or civic journalism, peace journalism, development journalism, citizen journalism, the street press, community journalism, social entrepreneurism, or other names. Countries that are studied in-depth include the United States, the United Kingdom, Germany, Finland, China, India, Japan, Indonesia, Australia, New Zealand, South Africa, Nigeria, Brazil, Colombia and Puerto Rico. Each of the approaches that are described offers a distinctive potential to support deliberative democracy. However, the book does not present any of these models or case studies as examples of categorical success. Instead, it explores different elements of the nature, strengths, limitations and challenges of each approach, as well as issues affecting their longer-term sustainability and effectiveness. The book also describes the underlying principles of deliberation, the media’s potential role in deliberation from a theoretical and practical perspective, and ongoing issues for deliberative media practitioners.

Conceptual models of satisfaction level in construction

It is recognized that, in general, the performance of construction projects does not meet optimal expectations. One aspect of this is the performance of each participant, which is interdependent and makes a significance impact on overall project outcomes. Of these, the client is traditionally the owner of the project, the architect or engineer is engaged as the lead designer and a contractor is selected to construct the facilities. Generally, the performance of the participants is gauged by considering three main factors, namely time, cost and quality. As the level of satisfaction is a subjective measurement, it is rarely used in the performance evaluation of construction work. Recently, various approaches to the measurement of satisfaction have been made in attempting to determine the performance of construction project outcomes – for instance client satisfaction, consultant satisfaction, contractor satisfaction, customer satisfaction and home buyer satisfaction. These not only identify the performance of the construction project, but are also used to improve and maintain relationships. In addition, these assessments are necessary for continuous improvement and enhanced cooperation between participants. The measurement of satisfaction levels primarily involves expectations and perceptions. An expectation can be regarded as a comparison standard of different needs, motives and beliefs, while a perception is a subjective interpretation that is influenced by moods, experiences and values. This suggests that the disparity between perceptions and expectations may be used to represent different levels of satisfaction. However, this concept is rather new and in need of further investigation. This paper examines the current methods commonly practiced in measuring satisfaction level and the advantages of promoting these methods. The results provided are a preliminary review of the advantages of satisfaction measurement in the construction industry and recommendations are made concerning the most appropriate methods for use in identifying the performance of project outcomes.

Expertise in software design : novice and expert models

This paper investigates how software designers use their knowledge during the design process. The research is based on the analysis of the observational and verbal data from three software design teams generated during the conceptual stage of the design process. The knowledge captured from the analysis of the mapped design team data is utilized to generate descriptive models of novice and expert designers. These models contribute to a better understanding of the connections between, and integration of, designer variables, and to a better understanding of software design expertise and its development. The models are transferable to other domains.

Enhancing the transition of commencing students into university : an institution-wide approach

The importance of the first year experience (FYE) to success at university is well documented and supported with the transition into university regarded as crucial. While there is also support for the notion that a successful FYE should have a whole-of-institution focus and models have been proposed, many institutions still face challenges in achieving institution-wide FYE program implementation. This paper discusses the origins, theoretical and empirical bases and structure of an institution-wide approach to the FYE. It uses a case study of the Transitions In Project (TIP) at the Queensland University of Technology to illustrate how institution-wide FYE program implementation can be achieved and sustained. TIP had four inter-related projects focussing on at-risk students, first year curriculum, learning resources and staff development. The key aim of TIP was to identify good practice and institutionalise it in a sustainable way. The degree of success in achieving this is evaluated.

In vivo performance of melimine as an antimicrobial coating for contact lenses in models of CLARE and CLPU

Purpose: One strategy to minimize bacteria-associated adverse responses such as microbial keratitis, contact lens–induced acute red eye (CLARE), and contact lens induced peripheral ulcers (CLPUs) that occur with contact lens wear is the development of an antimicrobial or antiadhesive contact lens. Cationic peptides represent a novel approach for the development of antimicrobial lenses.---------- Methods: A novel cationic peptide, melimine, was covalently incorporated into silicone hydrogel lenses. Confirmation tests to determine the presence of peptide and anti-microbial activity were performed. Cationic lenses were then tested for their ability to prevent CLPU in the Staphylococcus aureus rabbit model and CLARE in the Pseudomonas aeruginosa guinea pig model. ---------- Results: In the rabbit model of CLPU, melimine-coated lenses resulted in significant reductions in ocular symptom scores and in the extent of corneal infiltration (P < 0.05). Evaluation of the performance of melimine lenses in the CLARE model showed significant improvement in all ocular response parameters measured, including the percentage of eyes with corneal infiltrates, compared with those observed in the eyes fitted with the control lens (P ≤ 0.05). ---------- Conclusions: Cationic coating of contact lenses with the peptide melimine may represent a novel method of prevention of bacterial growth on contact lenses and consequently result in reduction of the incidence and severity of adverse responses due to Gram-positive and -negative bacteria during lens wear.

Experiences of the FIRST LEGO League in China and Australia

FIRST (For Inspiration and Recognition of Science and Technology) was initiated in the U.S. by accomplished inventor Dean Kamen in 1989. FIRST LEGO League (FLL) is one of the five competitions conducted by this organization. Dean’s vision was “to create a world where science and technology are celebrated……where young people dream of becoming science and technology heroes”. Each year FLL creates opportunities for young people aged 9-16 to engage in problem solving, teamwork and collaborative learning around a real-world theme. In the 2009/2010 season, more than 145,000 young people in over 50 countries participated in this competition. As they tackle the challenges; they construct and de-construct their own knowledge through hands-on engagement in a constructivist learning environment. The challenges are presented at least eight weeks before the competition. In most events the participants are judged in four categories - robot game, robot design, team project and team challenge. “Gracious professionalism” is an essential element of the competition. This paper compares and contrasts the FLL in China and Australia and presents some of the achievements of the event. It also highlights some of the models which have been adopted in the two countries to facilitate participation. The educational benefits of embedding the FLL will also be discussed.

Copyrights and creative commons licensing : pedagogical innovation in a higher education media literacy classroom

This article examines the role of copyrights in contemporary media literacies. It argues that, provided they are ethical, young people’s engagement with text should occur in environments that are as free from restriction as possible. Discussion of open culture ecologies and the emergent education commons is followed by a theorisation of both literacy and copyrights education as forms of epistemology: that is, as effects of knowledge producing discourses and practices. Because Creative Commons licenses respect and are based on existing copyright laws, a brief overview of traditional copyrights for educators is first provided. We then describe the voluntary Creative Commons copyright licensing framework (“some rights reserved”) as an alternative to conventional “all rights reserved” models. This is followed by an account of a series of workshop activities on copyrights and Creative Commons conducted by the authors in the media literacy classes of a preservice teacher education program in Queensland, Australia. It provides one example of a practical program on critical copyrights approaches, which may be adapted and used by other school and higher education institutions.
