Evaluating the use of a Teacher’s Diary to illuminate the moral dimensions of a teacher educator’s everyday work.
No full textThis paper aims to evaluate my early attempts at using my Teacher’s Diary as a method (Aleskewski 2006, Holly & Altrichter 2011, Bold 2012) to gain a deeper insight into the moral dimensions of my day to day practice as a teacher educator in the tertiary sector in the UK. I chose this method of data collection firstly for its potential to be authentic, trustworthy and systematic due the very nature of the researcher as participant (Ellis 2004, 2009; Piper & Simons 2011) and secondly as a genuine method to interpret my everyday actions as moral ones. This evaluation aims to highlight the extent to which I was able to reach these aims as a novice auto-ethnographical researcher. Much of the literature reflecting upon the use of diaries and narratives in research is able to demonstrate the rich data that can emerge from the text that is then analysed and interpreted by both researcher and reader (Ellis 2004; Anderson 2006; Sparkes 2007; Kenton 2011; Bold 2012). This rich data is often put forward as best placed to help readers connect with the author and understand their experiences of their cultural context more fully. The first aim of this paper is to share my experiences of using this method of data collection by highlighting the contradictions and challenges and sometimes ‘messy’ nature of maintaining diaries (Holly & Altrichter 2011) within education research contexts as both the teacher-participant and researcher. The second aim of the paper is to reflect upon the usefulness of the dairy as a way of ‘seeing’ practice. The third aim is to briefly draw upon literature from the work of Pring (2001), Goodlad et al (1990) and Mahony (2009) and Fallona (2000) Noddings (2010) who suggest that teaching is a moral endeavour and that teacher’s morals can be visible in their practice and to analyse examples of the diary entries that show moral dimensions. The paper will add to the work of Webb & Blond (1995) and Husu & Tirri (2003) who also explore the extent to which a Teacher’s Diary can, in a practical way, show the moral aspects that arise, and the decisions taken, on a day to day basis by one teacher educator. The paper begins to highlight the extent to which morals can be taught or caught in this context, namely teacher education (Mahoney 2009), and makes the point as Kiss and Euban (2010) do, that developing the virtues of intellect either through explicit curriculum, pedagogical choices or institutional values, cannot be separated from developing virtues of character

Data source: Supporting information, https://doi.org/10.1021/acs.est.0c07136Chalcopyrite, galena, and sphalerite commonly coexist with pyrite in sulfidic waste rocks. The aim of this work was to investigate their impact, potentially by galvanic interaction, on pyrite oxidation and acid generation rates under simulated acid and metalliferous drainage conditions. Kinetic leach column experiments using single-minerals and pyrite with one or two of the other sulfide minerals were carried out at realistic sulfide contents (total sulfide 47% for galena vs <1.5% for chalcopyrite) over 72 weeks. The results are directly relevant to mine waste storage and confirm that the galvanic interaction plays a role in controlling acid generation in multisulfide waste even at low sulfide contents (several wt %) with small probabilities (≤0.23%) of direct contact between sulfide minerals in mixed sulfide experiments.Gujie Qian, Rong Fan, Jianyin Huang, Allan Pring, Sarah L.

Engravings and rock coatings at Pudjinuk Rockshelter No. 2, South Australia
No full textThis paper presents the results of analyses of rock coatings from Pudjinuk Rockshelter No. 2 in South Australia (SA) using the following methods: 1) Raman microscopy; 2) X-ray powder diffraction; and 3) Scanning electron microscopy coupled with integrated energy dispersive X-ray spectroscopy. The deposits analysed contained a mixture of thenardite, glauberite, halite, sylvinite, gypsum, probable palygorskite and amorphous carbon. The engravings previously extant at the rockshelter are also described and contextualised. This article provides the first record of thenardite in any context in SA. It is argued that the accumulation of the salt crystals, likely caused or exacerbated by run-off from irrigation, led to significant haloclasty (salt weathering) that caused or contributed to the destruction of the pre-contact petroglyphs in the rockshelter. The presence of amorphous carbon is interpreted as possibly deriving from firewood sources. The effects of salt weathering on petroglyphs in the Murray River Gorge, as demonstrated in this paper, reveals the urgent need for a systematic program of rock art recording in the region.Amy Roberts, Heather Burke, Allan Pring, Jing Zhao, Christopher T.Gibson, Rachel S.

The impact of bariatric surgery on young women’s quality of life, health behaviours and reproductive health.
No full textThe aim of this study is to explore the experiences of young women undergoing weight loss surgery in relation to quality of life and health behaviour issues with a focus on reproductive health. This is in light of the increasing numbers of women who have unsuccessfully tried conventional weight loss approaches and are now opting for surgical interventions in order to gain control of their weight and better assimilate into society. Weight loss operations refer to a collection of permanent and reversible surgical techniques collectively known as Bariatric Surgery (“BS”), which have been demonstrated to be an effective and viable treatment to sustain weight-loss in the severely obese. These operations are unique in that they also have a positive influence on other medical conditions and aid long-term health, including resolving menstrual irregularities leading to improved female fertility. In recent years there has been an increase in women aged 18-25 years who have undergone BS. This age bracket correlates with the natural ‘peak’ in fertility and inevitably leads to some early post-surgery pregnancies with an increase in the risk of adverse health issues for both mother and (foetal development) child.
Seven women (aged 18-25 years) responded via an on-line tool to share their experiences of undergoing BS, in one to one recorded interviews conducted via Skype. All had undergone surgery within the private sector and were 6-24 months post-surgery at the time of the interview. Thematic framework was used to analysis and understand the personal narratives and identify semantic themes. The participants described their experiences in terms of three broad themes i) identifying a problem, ii) seeking help and iii) reality check. Transcending these themes was the ‘cost’ which linked with the Subjective Expected Utility (SEU) Theory being the theoretical framework underpinning this study, based on the decision making model of behaviour (Edward 1954). The majority of the participants described feeling optimistic after-surgery, however this was balanced against various costs (trade-offs) of positive/negative experiences and outcomes with a realisation for some that psychological issues still needed to be addressed.
These findings provide an insight to the physical and psychological experiences of young women who have undergone BS and offer awareness for health care professional and prospective participants considering/preparing to undergo BS

Reorganizations of space and culture in a car-oriented society: the case of Johannesburg
No full textIncludes abstract.This dissertation aims to identify the multi-faceted ways in which the car enabled a deep restructuring of South Africa's cultural and spatial spheres, taking Johannesburg as a context from which to extract specific insights. The two most popular modes of transportation in South Africa-the car and the minibus taxi-run on the nation's dominant system of highways and roads that came with the mass importation of the car. Because of their high usage, these two transportation modes are compared, contrasted and analyzed throughout the research. Non-instrumental factors associated with the two transport modes (i.e. a means to express oneself, social status, lifestyle and culture) are scrutinized. These factors shape transport choice and play an integral role in the relationships mobility has with space and culture. The car not only helped enable a dramatic shift in geography, but society at-large. This shift laid the groundwork for the desired lifestyle that is embodied by much of the alluring non-instrumental factors identified by respondents and the car advertisements reviewed. Conversely, this dissertation also identifies the multi-faceted ways people without cars participate in a ...... car-oriented society. The layers of informality within the minibus taxi industry, its social networks, culture and spatial organizations are analyzed and compared with that of the car. Transportation studies, government papers, theories within the disciplines of sociology, cultural studies and social psychology were integrated to support the research. Using grounded theory, this study also includes personal insights from private car and public transport users. Car advertisements produced by four of the top-selling car manufacturers in South Africa were reviewed using semiotic analysis and compared with participant responses. Rather than offering a theoretical solution to a car-oriented society, this dissertation offers a way to rethink the geography, lifestyle, culture, institutions, spaces and people associated with the private car and public transport. Ultimately, this may contribute to how a more positive characterization of public transport can be achieved.
A multidisciplinary investigation of a rock coating at Ngaut Ngaut (Devon Downs), South Australia
No full textThis paper presents the results of a multidisciplinary investigation into a dark rock coating at the Ngaut Ngaut heritage complex in South Australia (SA) using geological and botanical examination, Raman microscopy, x-ray powder diffraction, scanning electron microscopy and infrared analyses. The coating analysed contains a mixture of calcite, quartz, gypsum and weddellite. The presence of calcite and quartz can be explained by the underlying clastic fossiliferous limestone, while the most probable explanation for the origin of the gypsum is via ground water. The weddellite was likely formed from solutions derived from the reaction of calcite with oxalic acid through the intervention of surface microflora, such as algae. This article provides the first record of weddellite in any context in SA. These findings have a number of implications-one being that the oxalate mineral in the rock coating could potentially be used to conduct accelerator mass spectrometry radiocarbon analysis and thereby refine our understanding of the rock art chronology at Ngaut Ngaut. A greater understanding of the rates of accumulation may also be useful for management purposes, as the nature of the rock coating may be contributing to long-term exfoliation. Indeed, it is argued that algal colonisation of the limestone (together with other probable microfloral activities) is likely involved in the production of a film over the porous surface, leading to salt weathering.Amy Roberts, Isobelle Campbell, Allan Pring, Graham Bell, Alan Watchman, Rachel S.

Connecting does not necessarily mean learning: Course handbooks as mediating tools in school-university partnerships
No full textThis is the author's accepted manuscript (titled "Course handbooks as mediating tools in learning to teach"). The final published article is available from the link below. Copyright @ 2011 American Association of Colleges for Teacher Education.Partnerships between schools and universities in England use course handbooks to guide student teacher learning during long field experiences. Using data from a yearlong ethnographic study of a postgraduate certificate of education programme in one English university, the function of course handbooks in mediating learning in two high school subject departments (history and modern foreign languages) is analyzed. Informed by Cultural Historical Activity Theory, the analysis focuses on the handbooks as mediating tools in the school-based teacher education activity systems. Qualitative differences in the mediating functions of the handbooks-in-use are examined and this leads to a consideration of the potential of such tools for teacher learning in school–university partnerships. Following Zeichner’s call for rethinking the relationships between schools and universities, the article argues that strong structural connections between different institutional sites do not necessarily enhance student teacher learning
