WATER TRANSPORT THROUGH POROUS MEDIA AND IN FLOW CHANNELS OF PROTON EXCHANGE MEMBRANE FUEL CELL

Proton exchange membrane (PEM) fuel cell has been known as a promising power source for different applications such as automotive, residential and stationary. During the operation of a PEM fuel cell, hydrogen is oxidized in anode and oxygen is reduced in the cathode to produce the intended power. Water and heat are inevitable byproducts of these reactions. The water produced in the cathode should be properly removed from inside the cell. Otherwise, it may block the path of reactants passing through the gas channels and/or gas diffusion layer (GDL). This deteriorates the performance of the cell and eventually can cease the operation of the cell. Water transport in PEM fuel cell has been the subject of this PhD study. Water transport on the surface of the GDL, through the gas flow channels, and through GDL has been studied in details. For water transport on the surface of the GDL, droplet detachment has been measured for different GDL conditions and for anode and cathode gas flow channels. Water transport through gas flow channels has been investigated by measuring the two-phase flow pressure drop along the gas flow channels. As accumulated liquid water within gas flow channels resists the gas flow, the pressure drop increases along the flow channels. The two-phase flow pressure drop can reveal useful information about the amount of liquid water accumulated within gas flow channels. Liquid water transport though GDL has also been investigated by measuring the liquid water breakthrough pressure for the region between the capillary fingering and the stable displacement on the drainage phase diagram. The breakthrough pressure has been measured for different variables such as GDL thickness, PTFE/Nafion content within the GDL, GDL compression, the inclusion of a micro-porous layer (MPL), and different water flow rates through the GDL. Prior to all these studies, GDL microstructural properties have been studied. GDL microstructural properties such as mean pore diameter, pore diameter distribution, and pore roundness distribution have been investigated by analyzing SEM images of GDL samples.

Clinical skills and communication in nursing students

Abstract Background: Communication is a basic tool in nursing, a crucial element of care. The quality of the interactions that take place between the nurse and the user/family influence their satisfaction and security felt with the care received. Objectives: To identify the communication skills and interpersonal relationship of nursing students in health care; identify the sociodemographic and academic variables influencing communication skills and interpersonal relationship of nursing students in health care. Methodology: Quantitative study, cross-sectional, descriptive and correlational. The data collection instrument was a questionnaire with questions concerning the socio-demographic and academic characterization; basic skills of interview and clinical communication in health care; learning of clinical communication skills and range of communication skills and interpersonal relationship. The sample consisted of 374 nursing students from two Portuguese schools. Results: The majority were female (80.5%), in the age group of 18-21 years. The students recognize the importance of clinical communication skills and interpersonal relations in nursing practice (82.4%); agreed on the teaching methods of communicational skills (54.3%). Evaluated their training in the area as good (71.7%). Age, semester and school influenced communication skills and interpersonal relationship of students (p <0.5) Conclusion: The results obtained allow us to state that the education / training of nursing student in the relational context is of fundamental importance in building capacity for competent professional practice.

Youth Festival Music Performance : Deception Bay

Research Background - Young people with negative experiences of mainstream education often display low levels of traditional academic achievement. These young people tend to display considerable cultural and social resources developed through their repeated experiences of adversity. Education research has a duty to provide these young people with opportunities to showcase, assess and translate their social and cultural resources into symbolic forms of capital. This creative work addresses the following research question. How can educators develop disengaged teenager's social and cultural capital through live music performances? Research Contribution - These live music performances afford the young participants opportunities to display their artistic, technical, social and cultural resources through a popular cultural format. In doing so they require education institutions to provide venues that demonstrate the skills these young people acquire through flexible learning environments. The new knowledge derived from this research focuses on the academic and self confidence benefits for disengaged young people using festival performances as authentic learning activities. Research Significance - This research is significant because it aims to maximise the number of tangible outcomes related to a school-based arts project. The young participants gained technical, artistic, social and commercial skills during this project. This performance led to more recording and opportunities to perform at other youth festivals in SE QLD. Individual performances were distributed and downloaded via creative commons licences at the Australian Creative Resource Archive. It also contributed to their certified qualifications and acted as pilot research data for two competitively funded ARC grants (DP0209421 & LP0883643)

Frock paper scissors : a comparative case study

This paper discusses the ways in which synergies across design disciplines can be developed through student engagement on authentic design projects. The paper focuses on a comparative case study where students from the Fashion, and Communication Design discipline areas in the Creative Industries Faculty at Queensland University of Technology (QUT) work on the production of the Frock Paper Scissors magazine and web site. The Frock Paper Scissors magazine has been the focus of assessment in a Fashion and Style Journalism class for the last three years, and for the last two years, students from an Advanced Web Design class have been involved in the production of the accompanying web site, http://frockpapersissors.com/. In this paper we focus on how this authentic assessment task has been integrated into the two design (and communication) classes; discussing the different approaches taken by teaching staff, the challenges faced, and the ways in which student learning outcomes have been improved through interactions between design disciplines. The paper concludes by outlining a set of observations on how to successfully engage students from different design (and creative industries) fields on an authentic design project within their studies.

That's how it was, this is how it is

Research Background : Young people with negative experiences of mainstream education often display low levels of traditional literacy. These young people tend to display considerable cultural and social resources developed through their repeated experiences of adversity. Education research has a duty to provide these young people with opportunities to showcase, assess and translate their social and cultural resources into symbolic forms of capital. This creative work addresses the following research question. How can educators encourage disengaged youth to showcase their social and cultural capital through non-traditional literacy practices?----- Research Contribution : This DVD production of a music video affords the young participants opportunities to display their artistic, technical, social and cultural resources through a popular cultural format. In doing so it requires education institutions to assess alternative student outputs that demonstrate the skills these young people acquire as they re-engage in flexible learning environments. The new knowledge derived from this research centres on the retention and certification benefits for disengaged young people using popular culture and social enterprise as authentic learning activities.----- Research Significance : This research is significant because it aims to maximise the number of tangible outcomes related to a school-based arts project.

Characterising creativity : a holistic methodology for the assessment of creative works

This paper reports on the early stages of a design experiment in educational assessment that challenges the dichotomous legacy evident in many assessment activities. Combining social networking technologies with the sociology of education the paper proposes that assessment activities are best understood as a negotiable field of exchange. In this design experiment students, peers and experts engage in explicit, "front-end" assessment (Wyatt-Smith, 2008) to translate holistic judgments into institutional, and potentiality economic capital without adhering to long lists of pre-set criteria. This approach invites participants to use social networking technologies to judge creative works using scatter graphs, keywords and tag clouds. In doing so assessors will refine their evaluative expertise and negotiate the characteristics of creative works from which criteria will emerge (Sadler, 2008). The real-time advantages of web-based technologies will aggregate, externalise and democratise this transparent method of assessment for most, if not all, creative works that can be represented in a digital format.

Young children’s experience of visual displays of their artwork

The practice of displaying children's artwork in early childhood classrooms poses a number of questions about the child and his or her visual artwork. This paper focuses on young children’s experiences with the display of their own visual artwork. Following Giorgi's (1985a; 1985b) approach to conducting phenomenological psychological research, 13 children between the ages of 4 and 6 years attending an independent school outside metropolitan Detroit, Michigan (USA) participated in semi-structured interviews as a way of uncovering their lived experiences of seeing their artwork displayed. The study yielded 12 essential themes and from these three key issues and their implications for early childhood art education are explored.

Generative systems as relational bridges

Generative media systems present an opportunity for users to leverage computational systems to make sense of complex media forms through interactive and collaborative experiences. Generative music and art are a relatively new phenomenon that use procedural invention as a creative technique to produce music and visual media. These kinds of systems present a range of affordances that can facilitate new kinds of relationships with music and media performance and production. Early systems have demonstrated the potential to provide access to collaborative ensemble experiences to users with little formal musical or artistic expertise. This paper examines the relational affordances of these systems evidenced by selected field data drawn from the Network Jamming Project. These generative performance systems enable access to unique ensemble with very little musical knowledge or skill and they further offer the possibility of unique interactive relationships with artists and musical knowledge through collaborative performance. In this presentation I will focus on demonstrating how these simulated experiences might lead to understandings that may be of educational and social benefit. Conference participants will be invited to jam in real time using virtual interfaces and to view video artifacts that demonstrate an interactive relationship with artists.

Editorial

This special issue of the Journal of Community, Citizen’s and Third Sector Media and Communication (3CMedia) is based on selected presentations given at the 5th annual Making Links conference, held at The University of Melbourne from 11th to 13th November, 2008.

One of the program streams at this conference was dedicated to the practice of digital storytelling (Lambert, 2002; Hartley & McWilliam, 2009).

Developing authentic achievement for disengaged young people using an electronic portfolio system

Credentials are a salient form of cultural capital and if a student’s learning and productions are not assessed, they are invisible in current social systems of education and employment. In this field, invisible equals non-existent. This paper arises from the context of an alternative education institution where conventional educational assessment techniques currently fail to recognise the creativity and skills of a cohort of marginalised young people. In order to facilitate a new assessment model an electronic portfolio system (EPS) is being developed and trialled to capture evidence of students’ learning and their productions. In so doing a dynamic system of arranging, exhibiting, exploiting and disseminating assessment data in the form of coherent, meaningful and valuable reports will be maintained. The paper investigates the notion of assessing development of creative thinking and skills through the means of a computerised system that operates in an area described as the efield. A model of the efield is delineated and is explained as a zone existing within the internet where free users exploit the cloud and cultivate social and cultural capital. Drawing largely on sociocultural theory and Bourdieu’s concepts of field, habitus and capitals, the article positions the efield as a potentially productive instrument in assessment for learning practices. An important aspect of the dynamics of this instrument is the recognition of teachers as learners. This is seen as an integral factor in the sociocultural approach to assessment for learning practices that will be deployed with the EPS. What actually takes place is argued to be assessment for learning as a field of exchange. The model produced in this research is aimed at delivering visibility and recognition through an engaging instrument that will enhance the prospects of marginalised young people and shift the paradigm for assessment in a creative world.
