Surface-sensitive method to determine calcium carbonate filler contents in cellulose matrices

This paper describes a method using attenuated total reflectance infra-red spectroscopy to determine the surface concentration of calcium carbonate in paper samples, by applying the linear relationship between the relative infra-red absorption integrals and the concentration. The method was able to detect micro-variations in the surface concentration and could also distinguish between different sheets as well as between the top and bottom side of one sheet. The samples were also split and the calcium carbonate concentration was determined within and compared to bulk calcium carbonate concentration determined from ash testing. The surface results were also compared with analysed scanning electron microscopy images generated from back-scattering electrons. The comparison shows that both sets of results are in excellent agreement. Depending on the sample, large errors (95% confidence) were observed. These, however, are caused by micro-variations of the surface concentration, rather than by inaccuracies of the technique, which is estimated to be less than 1%. Furthermore, measurements of various sample orientations suggest that anisotropic polarisation effects can be neglected. The method can be applied to paper and cellulose matrices having calcium carbonate filler contents of less than 50%. Due to spectral overlaps it is not suitable to determine kaolin filler contents.

A dinner party: setting the table

A Dinner Party: setting the table, is a collaborative project curated by Caroline Phillips and Victoria Duckett. It is a cross- media workshop and forum that brings a range of feminist artists, scholars, and social commentators together to explore feminist art today. The project is the first step towards the realization of a larger feminist exhibition (The F Word) which will tour regional Victoria in 2014, later coming to rest in Melbourne.

Using Judy Chicago’s iconic feminist work The Dinner Party (1974 – 1979) as a starting point for research and dialogue, the workshop will explore the local questions and challenges which drive feminist art today. It is also space in which we will together develop feminist artwork.

Spirituality, music, and wellbeing : sharing insights from an Australian setting

The relationship between spirituality, music, health, and wellbeing is gaining much theoretical and research attention globally. These related concepts are complex and involve many facets and challenges. This paper explores the relationship between music and spirituality as a way to communicate actively with God, which interconnects with wellbeing and quality of life. The focus of this paper discusses one case study from my wider research project “Spirituality and Wellbeing: Music in the Community” that started in 2013, in Melbourne (Australia). Having gained ethical clearance, case study methodology (interviews, documents, and observation) was employed. For this paper, I only offer a discussion of semi-structured interviews with volunteer participants from an Anglican Church in the southeastern suburbs of Melbourne (Australia). Using interpretative phenomenological analysis (IPA), I analyzed and codified the interview data to explore the lived experience of the participant’s perception and how they make sense of it. As IPA is phenomenological, it takes into the account my own ideas through a process of interpretation when analyzing the phenomena under study. The interview data are reported under two overarching themes: music and spirituality and music and wellbeing. The data provides insights into the various ways music contributes to participants’ spiritual journey and growth. I argue that music is a powerful vehicle that connects people with God and others as it fosters an enhanced sense of spiritual growth and self-wellbeing.

Critical literacy in an Indonesian EFL setting: sustaining professional learning

 This study investigates factors leading to the successful design and implementation of critical literacy pedagogy in an English as a Foreign Language (EFL) class at a secondary school in the city of Bandung, West Java, Indonesia. Critical literacy pedagogy appears to have helped students to become more critical and socially aware.

A novel approach to priority-setting for HIV prevention among adults in Uganda

 The study used economic and ethical theory, empirical evidence and local stakeholders views to develop a checklist of features of an ideal approach to priority-setting. This was used to determine the ideal approach for priority-setting for HIV prevention in Uganda. The Assessing Cost-Effectiveness (ACE) approach was determined to be the ideal approach using the checklist developed. A pilot study using the approach determined that in Uganda, blood safety and HIV counselling interventions are the most cost-effective, equitable and acceptable interventions. Mass media interventions were the least cost-effective and affordable, had a weak evidence base but were more acceptable. On the other hand interventions targeting Most-at-risk-populations were cost-effective but least acceptable. The study demonstrates the importance of balancing technical rigor and due process to ensure buy-in by stakeholders.

Tissue engineered, biomimetic acellular matrices for expansion of hematopoietic progenitors

This thesis discusses a novel strategy for ex vivo expansion of human HSPC in a cell free culture system and it suggests methods to improve the functional properties of stromal cell derived ACMs to support ex-vivo HSPC growth.
