MBA experience by distance education : an ethnographic study of a professional development program

The author's ethnographic study of a professional development program for managers and aspiring managers taught at a distance intends to make a substantial contribution to both the theory and practice of continuing education for professionals. The study focused on a group of Deakin University Master of Business Administration (MBA) participants and their experiences of the final two years of the program. Theorising on the professional development experience was based on data gathered from the direct observation of participants working in their study groups and at residential schools. Moreover, data drawn from end-of-year interviews with participants and discussions with MBA teachers also contributed to the theorising process. Theorising spanned a broad set of interactions encompassing participants' formal educational, professional and personal worlds. The thesis is devoted to two aspects of the professional development experience, namely: participants' interactions in their study groups and at residential schools; and participants' attempts to grow and develop as competent professional practitioners during their MBA studies. Interactions with key learning contexts orchestrated by the teaching institution (i.e. study groups and residential schools) are grounded in an analysis of the changing group cultures observed to accommodate the different educational demands of the program. Group interaction on a broader scale is also analysed in the context of the residential schools. The residential school provided a powerful forum for the development of participant activism over the future development of the MBA program. The analysis of the study groups in action led the author to identify the key characteristics of effective educational work groups. The implications of the success of these essentially egalitarian and leaderless groups for the formation of self-managed groups in the workplace is examined. On the matter of professional development, the author reveals the relationships between the nature of participants' jobs, their search for professional integration, their stage of professional empowerment, the strategies they pursued either to empower themselves or others in their organisations and the barriers which were encountered in the pursuit of empowerment. Dramatic examples of professional disempowerment are analysed indicating that interaction between formal off-the-job learning and professional practice in the workplace is not necessarily a smooth and positive experience. The group of participants studied are seen to be heterogeneous in relation to the above factors characterising professional development The implications of the theorising are considered in relation to professional pedagogies, assessment strategies and distance education. Distance education is seen to socially construct the roles of both teachers and students in the educational process. Specifically, teachers are seen to be somewhat marginalised during the program in use whereas the participants are located at the centre of the educational experience. The primacy of participants in the educational process is highlighted through the growing reliance on self-and peer-group assessment skills as participants progressed through the program. It is argued that the teaching institution should encourage and maintain the development of these skills as they represent a major learning outcome of the professional development experience, i.e. the ability to engage in the process of critical self-reflection and informed action.

Feminist poetics : symbolism in an emblematic journey reflecting self and vision

My thesis tilled Feminist Poetics: Symbolism in an Emblematic Journey Reflecting Self and Vision, consists of thirty oil paintings on canvas, several preparatory sketches and drawings in different media on paper, and is supported and elucidated by an exegesis. The paintings on unframed canvases reveal mise en scčnes and emblems that present to the viewer a drama about links between identities, differences, relationships and vision. Images of my daughter, friends and myself fill single canvases, suites of paintings, diptyches and triptychs. The impetus behind my research derives from my recognition of the cultural means by which women's experience is excluded from a representational norm or ideal. I use time-honoured devices, such as, illusionist imagery, aspects of portraiture, complex fractured atmospheric space, paintings and drawings within paintings, mirrors and reflective surfaces, shadows and architectural devices. They structure my compositions in a way that envelops the viewer in my internal world of ideas. Some of these features function symbolically, as emblems. A small part of the imagery relies on verisimilitude, such as my hands and their shadow and my single observing eye enclosed by my glasses. What remains is a fantasy world, ‘seen’ by the image of my other eye, or ‘faction’, based on memories and texts explaining the significance of ancient Minoan symbols. In my paintings, I base the subjects of this fantasy on my memories of the Knossos Labyrinth and matristic symbols, such as the pillar, snake, blood, eye and horn. They suggest the presence of a ritual where initiates descended into the adyton (holy of holies) or sunken areas in the labyrinth. The paintings attempt a ‘rewriting’ of sacrality and gender by adopting the symbolism of death, transformation and resurrection in the adyton. The significance of my emblematic imagery is that it constructs a foundation narrative about vision and insight. I sought symbolic attributes shared by European oil painting and Minoan antiquity. Both traditions share symbolic attributes with male dying gods in Greek myths and Medusa plays a central part in this linkage. I argue that her attributes seem identical to both those of the dying gods and Minoan goddesses. In the Minoan context these symbols suggest metaphors for the female body and the mother and daughter blood line. When the symbols align with the beheaded Medusa in a patriarchal context, both her image and her attributes represent cautionary tales about female sexuality that have repercussions for aspects of vision. In Renaissance and Baroque oil painting Medusa's image served as a vehicle for an allegory that personified the triumph of reason over the senses. In the twentieth century, the vagina dentata suggests her image, a personified image of irrational emotion that some male Surrealists celebrated as a muse. She is implicated in the male gaze as a site of castration and her representation suggests a symbolic form pertaining to perspective. Medusa's image, its negative sexual and violent connotations, seemed like a keystone linking iconographic codes in European oil painting to Minoan antiquity. I fused aspects of matristic Minoan antiquity with elements of European oil paintings in the form of disguised attribute gestures, objects and architectural environments. I selected three paintings, Dürer's Setf-Portrait, 1500, Gentileschi's Self-Portrait as the Allegory of Painting, 1630 and Velazquez's Las Meniruis, 1656 as models because 1 detected echoes of Minoan symbolism in the attributes of their subjects and backgrounds. My revision of Medusa's image by connecting it to Minoan antiquity established a feminist means of representation in the largely male-dominated tradition of oil painting. These paintings also suggested painting techniques that were useful to me. Through my representations of my emblematic journey I questioned the narrow focus placed on phallic symbols when I explored how their meanings may have been formed within a matricentric culture. I retained the key symbols of the patriarchal foundation narratives about vision but removed images of violence and their link to desire and replaced it with a ritual form of symbolic death. I challenged the binary oppositional defined Self as opposed to Other by constructing a complex, fluid Self that interacts with others. A multi-directional gaze between subjects, viewers and artist replaces the male gaze. Different qualities of paint, coagulation and random flow form a blood symbolism. Many layers of paint retaining some aspects of the Gaze and Glance, fuse and separate intermittently to construct and define form. The sense of motion and fluidity constructs a form of multi-faceted selves. The supporting document, the exegesis is in two parts. In the first part, I discuss the Minoan sources of my iconography and the symbolic gender specific meanings suggested by particular symbols and their changed meanings in European oil painting, I explain how I integrate Minoan symbols into European oil paintings as a form of disguised symbolism. In the second part I explain how my alternative use of symbolism and paint alludes to a feminist poetic.

In vitro and immunological assessment of the estrogenic activity and concentrations of 17β-estradiol, estrone, and ethinyl estradiol in treated effluent from 45 wastewater treatment plants in Victoria, Australia

The project was conducted between May 2006 and September 2007, and involved the collection of effluent samples from 45 wastewater treatment plants (WWTPs). The 45 WWTPs included 16 lagoon-based plants and 29 with activated sludge-based processes. Permission was obtained from all the relevant water authorities to collect samples of final effluent at point of discharge to the environment, whether that was to a creek, a river, the ocean, or the land. Samples were collected on two occasions, namely, in August 2006 (winter) and late February–early March 2007 (summer), and subjected to a number of biological and chemical analyses, including toxicity tests, measurement of hormonal (estrogenic) activity using yeast-based bioassays, and measurement of specific hormonal concentrations using enzyme-linked immunosorbent assays (ELISAs). Almost all of the effluents examined showed estrogenic activity: in winter, no activity to 73 ng/l 17β-estradiol equivalents (EEQ); and in summer, no activity to 20 ng/l EEQ. On the whole, the levels of estrogenic activity observed were comparable with the range recently reported in Australia and New Zealand using human estrogen receptor-based assays (“not detected” to ~10 ng/l EEQ). The low/no bioassay response was confirmed by the chemical assessment of estradiol, estrone, and ethinyl estradiol concentrations by ELISA, which returned concentrations of these compounds for the most part below 10 ng/l.

The entrepreneurial self and youth at-risk : exploring the horizons of identity in the 21st century

This paper argues that a particular form of selfhood has come to dominate the horizons of identity in the Western democracies at this time - I refer to this form of personhood as the entrepreneurial self. The paper argues that the figure (population) of ‘Youth at-risk’, in its negativity, illuminates the positivity that is the entrepreneurial Self. That is, the discourses that construct Youth at-risk reveal the truths about whom we should, as adults, become. The paper engages with Foucault’s theories of government, of (Neo)Liberalism as a problematisation of the practise of Liberal welfare government, and of the ways in which certain psychological discourses articulate with (Neo)Liberal views of enterprise to produce a view of the Self as the entrepreneurial Self.

Australia’s savanna herbivores : bioclimatic distributions and an assessment of the potential impact of regional climate change

The future impacts of climate change are predicted to significantly affect the survival of many species. Recent studies indicate that even species that are relatively mobile and/or have large geographic ranges may be at risk of range contractions or extinction. An ecologically and evolutionary significant group of mammals that has been largely overlooked in this research is Australia’s large marsupial herbivores, the macropodids (kangaroos). The aims of our investigation were to define and compare the climatic conditions that influence the current distributions of four sympatric large macropodids in northern Australia (Macropus antilopinus, Macropus robustus, Macropus giganteus, and Macropus rufus) and to predict the potential future impact of climate change on these species. Our results suggest that contemporary distributions of these large macropodids are associated with well‐defined climatic gradients (tropical and temperate conditions) and that climatic seasonality is also important. Bioclimatic modeling predicted an average reduction in northern Australian macropodid distributions of in response to increases of 2.0°C. At this temperature, the distribution of M. antilopinus was reduced by . We predict that increases of 6.0°C may cause severe range reductions for all four macropodids ( ) in northern Australia, and this range reduction may result in the extinction of M. antilopinus.

Performing self and other in architecture : Staging Zaha Hadid

London-based Iraqi-born architect, Zaha Hadid, is often portrayed as extravagant and exotic; an image reinforced by her sense of fashion and her passion for the clothes of Japanese designer, Issey Miyake. By examining some of the ways that Zaha Hadid has staged herself as an architect, this article links notions of performance with processes of becoming an architect. It argues that Hadid is marked by traces of otherness–gender, culture, race–which give rise to questions about the story of the master architect dominating a westernized history of architecture and art.

Extended self and possessions in the workplace

This study of the meanings of possessions displayed in the offices of employees in a high technology firm suggests extensions to the concept of extended self. Work self and home self contend for dominance in these displays. Employees must decide which aspects of the self belong to the domain of work and which belong elsewhere. In these ongoing negotiations self may be extended, but it may also be retracted and hidden. Furthermore, although possessions can serve to stabilize the self, they also facilitate shifting among various self-aspects in response to workplace events. We explicate these processes and discuss implications for extended self theory.

Peak picking and the assessment of separation performance in two-dimensional high performance liquid chromatography

An algorithm was developed for 2DHPLC that automated the process of peak recognition, measuring their retention times, and then subsequently plotting the information in a two-dimensional retention plane. Following the recognition of peaks, the software then performed a series of statistical assessments of the separation performance, measuring for example, correlation between dimensions, peak capacity and the percentage of usage of the separation space. Peak recognition was achieved by interpreting the first and second derivatives of each respective one-dimensional chromatogram to determine the 1D retention times of each solute and then compiling these retention times for each respective fraction ‘cut’. Due to the nature of comprehensive 2DHPLC adjacent cut fractions may contain peaks common to more than one cut fraction. The algorithm determined which components were common in adjacent cuts and subsequently calculated the peak maximum profile by interpolating the space between adjacent peaks. This algorithm was applied to the analysis of a two-dimensional separation of an apple flesh extract separated in a first dimension comprising a cyano stationary phase and an aqueous/THF mobile phase as the first dimension and a second dimension comprising C18-Hydro with an aqueous/MeOH mobile phase. A total of 187 peaks were detected.

Communities, networks, individuals : place, self and everyday life on the internet

In this paper, I review the long-established use of the concept of ‘community’ which attempts both to perceive and analyse the experience of human interaction, mediated by networked computing. Ever since this form of communication commenced, it was clear that it was no ‘bloodless technological ritual’ (Rheingold, 1994), but something much more deeply human and expressive. For many years, the conceptual apparatus of ‘community’ served as the primary means for understanding the limits and potentials of this activity. However, the recent rise of social networking and social media might cast doubt on the legitimacy of this contested term’s continued relevance. Thus, I move from community to self, via the network notation that has come now to dominate our terminologies. I seek to demonstrate that, as the Internet has become interleaved with everyday life to the point where there is no distinction, for many people, between online and offline, we need to think again about how and what community might mean. In doing so, I suggest that the relationship between self and others, mediated or otherwise, is always one of shared ‘place’ but that contemporary practices of social networking differ significantly in how that place is shared and the degree of collective effort required.

Fear of self and obsessionality: development and validation of the Fear of Self Questionnaire

Obsessions – particularly those directly relating to causing harm – often contain or imply evaluative dimensions about the self, reflecting a fear as to who the person might be – or might become. Following from research indicating that such beliefs are relevant to OCD, and the wider literature in social psychology regarding ‘feared’ or ‘undesired’ self-guides, the current study describes the development and validation of a new questionnaire—the Fear of Self Questionnaire, in 8- and 20-item versions.

The questionnaire was piloted in two non-clinical samples (n=258; n=292). Exploratory and confirmatory factor analyses supported the unidimensionality of the measure. The questionnaire showed a strong internal inconsistency, and good divergent and convergent validity, including strong relationships to obsessional symptoms and with other processes implicated in cognitive models of OCD (e.g. obsessive beliefs, inferential confusion). Implications are discussed.
