The decline of experts in the Age of web 2.0 : lay blogger perceptions of experts

With the advent of Web 2.0 tools such as Weblogs (blogs), lay people can more easily share knowledge with the public and have far greater reach and impact. At the same time a literature review reveals that experts have been criticised on many fronts. This paper explores key criticisms of experts using 1) a literature review and 2) an interpretive study of lay blogger perceptions of experts. The paper provides important insights into lay blogger criticisms of experts. Findings indicate that a major lay blogger criticism of experts is class-based and powerbased. Experts are perceived as elitists who wish to control the flow of knowledge. Interestingly, many of the lay bloggers studied held mixed feelings about experts and the value of lay knowledge on the internet. Implications for theory and practice are discussed.

Does the inclusion of moderate amounts of red meat in the diet of exercising older women impact on faecal markers of bowel health, including faecal lactoferrin?

Background: High intakes of red meat may be associated with increased risk of colorectal cancer (CRC), however, to determine CRC risk, it is important to assess faecal changes related to protein and carbohydrate metabolism.

Objective: To determine the influence of three weekly meals rich in red meat as opposed to a carbohydrate control diet on faecal markers which are involved in the aetiology of CRC.

Design: Twenty post-menopausal women (aged 60-75) undertook, 3 times a week for 12 weeks, a 30 minute exercise session followed immediately by a cooked meal that was high in lean red meat, low in carbohydrate (n= 10) or low in lean red meat, high in carbohydrate (n=10). Dietary fibre intake and macronutrients were kept constant. At the beginning and end of the study, three-day faecal samples were collected and by-products of protein fermentation and carbohydrate metabolism, undigested fibre residues, and faecal output and colonic bacterial microbiota changes measured.

Outcomes: No significant differences were observed in subjects on either diet when comparing faecal output, faecal pH, other faecal markers, nor faecal lactoferrin. There was a trend observed in changes in the population of colonic microbiota using FISH analysis. Bacteroides spp. and Prevotella spp. appeared to decrease in women consuming a high red meat diet compared with an increase in women consuming a high carbohydrate diet.

Conclusions: In this pilot study the trend in colonic microbiota change is interesting and suggests that dietary influence of colonic microbiota, especially changes in Bacteroidetes, may be indicative of risk of gut damage and disease compared to other faecal markers.

Sources of stress in South African soccer coaches

It has been noted that coaches face a number of challenges, frustrations, conflicts and tensions, most of which translate into perceived stress. With the re-entry of South Africa into the international sporting arena, little is known about South African coaches and what specific stresses they experience. Thus, the present study used a mixed-method approach in exploring the perceptions of stress among South African soccer coaches. More specifically, 12 South African coaches were interviewed (using semi-structured interview guides) on their perceptions of sources of stress. Furthermore, 112 soccer coaches (at the provincial level and higher) were approached to complete a 32-item questionnaire on the sources of stress related to their job as coaches. Content analysis was used to evaluate the qualitative data while the descriptive data analysis was completed using the Statistical Package for Social Sciences (SPSS – version 16). The reliability was tested for the sources of stress (a= .817) for the 32 items. The sources of stress experienced by the coaches were evaluated. The results revealed the three main themes related to sources of stress were Resource Issues, External Pressure and Internal Capacity. Complementing these results, the top three sources of stress found through the descriptive statistics were lack of resources, fixture backlog and games where the outcome is critical, while the lowest three sources of stress were political interference, physical assaults from players and substituting a player. Specific academic and practical implications of the study the results were discussed.

Practitioner perceptions of sustainability in the Building Code of Australia

Buildings have a significant impact on environmental quality, resource use, human health and productivity. One definition of sustainable building is that which meets current building needs and reduces impacts on future generations by integrating building materials and methods that promote environmental quality, economic vitality, and social benefit’ (City of Seattle, 2006). In response to a changing view of
sustainability the Building Code of Australia (BCA) adopted energy measures in 2005 to residential buildings and, in 2006, to Class 1 – 9 buildings. In many respects the measures represented a watershed for the Australian Building Regulations which had not included sustainability within the BCA. The goals of the BCA are to enable the achievement and maintenance of acceptable standards of structural sufficiency, safety (including safety from fire), health and amenity for the benefit of the community now and in the future (ABCB, 2004a). As with any change some Building Surveyors and construction practitioners viewed these measures with apprehension. How would the measures be assessed? Furthermore, was the BCA the appropriate place for these measures and was this a broadening of the scope of the building regulations beyond
its traditional remit of health and life safety in buildings? This research used a questionnaire survey the canvass the views and perceptions of Building Surveyors and Architects with regards to sustainability and the BCA in 2006.

Perceptions of the value of site visits in assisting undergraduate learning

This study evaluates the usefulness of site visits in assisting the learning experience of undergraduate students. The research is based on a survey of undergraduates students enrolled in built-environment courses in property and construction. Past research has shown that it is becoming more difficult to provide students with access to building sites to provide learning experiences. While students were positive about the benefits of real site visits, universities have been encouraged to develop virtual approaches to teaching construction technology using photographs, movies and computer simulations.

This strategic research investigates the perceptions of students towards a number of different site visits each with particular characteristics. This was done to examine the most effective use of real site visits within an undergraduate course. The results identified that some aspects of construction technology could be easily replaced by computer simulations and the like. However, other aspects of the curriculum are more effectively taught by retaining real site visits. The research was intended to provide a more structured approach to determining the value of site-based learning in construction related courses.

Changing bodies, changing discourses : women's experiences of early menopause

Early menopause has been constructed by discourses of biological determinism as an untimely, but natural, failure of the female body. Medical discourses in particular have interpreted early menopause as a congenital irregularity and a rare anomaly of menopause at midlife. In this thesis I challenge the notion that early menopause is an innate imperfection related only to women’s age. I propose that early menopause is dependent upon the cultural interpretations of individual women and is constituted through the mercurial and multiple discourses of women who have this embodied experience. Moreover, I reveal that early menopause is a contemporary condition and that its location in history is inextricably bound to discourses of risk, naturalism and the self. Further I make the assumption that having an early menopause both affects and is an effect of women’s fertility, sexuality and subjectivity. I have drawn upon a broad range of sources to provide a sociological analysis of early menopause. Literature on early menopause is dominated by positivist discourses, yet many alternate discourses negotiate these influential constructions. I suggest here that the perception of early menopause as a natural fault is merely a construction by medical discourses and does not incorporate the dynamic discourses of early-menopausal women. Moreover, the restriction of early menopause to a genetic female failure excludes the majority of women who have an early menopause through iatrogenisis. This omission occurs through the failure of positivist discourses to accommodate diversity in discourses. Recent sociological and feminist studies have vindicated menopausal women. They have reconstructed menopause through notions of embodiment and have removed the veil of negativity used by the medical sciences to contain menopausal women (Komesaroff, Rothfield and Daly 1997). The visibility of menopausal women, however, remains connected to age. Menopause has been created as a predictable consequence of aging and as such has come to be synonymous with middle age. Nowadays, even men are said to experience menopause at midlife (Carruthers 1996). But early menopause is constituted within the discourses of women who have this experience. Medico-scientific discourses, based upon theories of genetic inevitability, disregard this perspective. Consequently early menopause is subsumed by naturalistic discourses that relate menopause to midlife. Such restraint reflects the unease created by menopause that does not coincide with prescribed life stages. Women's experiences of their changing bodies are largely unheard. Thus, women who have an early menopause are faced with a chasm of ‘cultural non-recognition’ (Fraser 1997). Conjointly with this discursive repression early-menopausal women face social imbalances that are transacted as both cause and consequence of early menopause. In particular the contemporary creation of early menopause is bound to the social and historical location of women as a group. Women are exploited by the institution of medicine, ‘exposure to environmental toxicity’ (Fraser 1997: 11) and commercialization as causes of early menopause. Yet the corporeal effects of practices of risk avoidance (Beck 1993), social practices (Shilling 1993) and Western consumerism (Lupton 1994) fail to be recognized. I address these problematics through a poststructural and feminist critique that assumes moments of commonality among women, while at the same time recognizes shifting and multiple differences (Nicholson 1999). I suggest here that early menopause falls into cultural misrecognition in Fraser's (1997) terms and argue that it is united concurrently with the gender injustice of androcentrism (Fraser 1997: 21). Fraser (1997: 16) suggests that it is only by relating these dual problematics that we are able to make sense of current dilemmas. Thus I have critiqued early menopause through a connection between individual embodied experiences of early menopause and early menopause as a modern phenomenon that is specific to women. I have attempted to unravel these arguments that simultaneously call to ‘... abolish gender differentiation and to valorize gender specificity’ (Fraser 1997: 21) while at the same time acknowledging their interconnectedness. An approach of merely combining women’s discourses with overarching social issues would be inadequate as not only do these problematics intersect but they also can be opposed. As Fraser (1997: 25) notes with her theory, redressing one aspect of cultural or social analysis can further imbalance another. For instance making visible the diversity and uniqueness of individual experiences of early menopause could detract from acknowledging the contemporary construction of early menopause through social inequality. Crucial to this understanding is a destabilizing of the binary construction of differences between the sexes that makes way for a reconstruction of early menopause through ‘sexual slippage’ (Matus 1995). In this thesis I look for a subtlety between the particular and the collective that views early menopause as concurrently a singular and changeable experience as well as imbedded in social practice. I suggest that these concepts are entwined as interactive effects of early menopause. Thus I have analyzed the bivalent problematics of the embodiment and social location of early menopause as imbricated, dynamic and unending discourses. From this perspective I reviewed the literature that was available on early menopause. In Chapter One I look to descriptions of early menopause and note that it has disappeared into a conglomeration of disparate, mostly medical, discourses that are contradictory. Nevertheless medical discourses offer ‘conclusive’ definitions of early menopause that are based on naturalistic views of the body (Shilling 1994). The determinants used are inconsistent and do not include women's discourses of early menopause. Thus, dominant medical discourses obscure women’s embodied experiences of early menopause and ignore the contemporary causes of early menopause. In Chapter Two I examine the causes of early menopause as a way of explaining the disparity between medical discourses and my anecdotal observations of early menopause as a fairly common contemporary occurrence. The relatively recent escalation in gynaecological surgery, especially hysterectomy, appears to account almost single-handedly for early menopause as a current phenomenon. Moreover, the extraordinary number of women who have their uterus removed at hysterectomy can be interpreted as a modern implementation of ancient anxieties. Women's sexuality has been constructed throughout history as problematic and this unease has been translated through women's bodies as dangerous and in need of control (Greer 1992). Thus social concerns which have evolved historically have emerged through the representation of a woman's uterus as an unseen, dark and mysterious risk (Beck 1993). Medical discourses define this risk and are able to negate the so-called dangers of women's sexuality through the surgical removal of their organs. Widespread negotiation of medical discourses is apparent, as hysterectomy in the modern Western world is the most common of all surgical operations (Hufnagel 1989). It is overwhelmingly the most common cause of early menopause as well. I examine also the historical condemnation of infertile women and how this anxiety has been transposed to the modern world through the commercialization of reproduction. Transactions of this social unease can cause early menopause. For instance the medical technology of in-vitro fertilization (I.V.F.) has been offered as a panacea for the infertility of early menopause but, paradoxically, can cause early menopause as well. Conception through technology has been normalized as a viable option for women who are unable to conceive and understandings of I.V.F. have moved into everyday discourse. Medical discourses have constructed fertility as a saleable item and infertile women expect that they can purchase this merchandise. Human eggs have become lucrative commodities that now are available in the market place. Egg ‘donation’ for I.V.F. programs can hasten the attrition rate of eggs and can cause early menopause in some pre-menopausal women (Rowland 1992: 24). Even the recycling of a woman’s uterus supposedly has become a possibility through the transferring of this ‘used’ organ at hysterectomy to a recipient woman who can use the other woman’s uterus as a ‘gestational garage’ (Rogers 1998). In this way women have been disembodied as mechanical systems with inter-changeable body parts and the potentially detrimental consequences of these commercial transactions are ignored. In addition I show how early menopause can be caused by the connection between the self and the social structure. Women's subjectivity is constituted through the cultural discourses available to them and these discourses affect social behaviour (Lupton 1995). For instance smoking and dieting have been identified as causes of early menopause. These activities have been related to the creation of women’s bodies as hetero-sexually desirable and are endemic to young women (Evans-Young 1995). This suggests that cultural causes of early menopause are transactions of sexual politics. Yet there is a paucity of literature that acknowledges the relationship between women’s subjectivity and early menopause. Thus the second chapter exposes a link between sexual politics and causes of early menopause through women's relationships with risk, naturalism and the self. In Chapter Three I deconstruct early menopause through theoretical considerations. I rely on an overarching poststructuralism that embraces the concept of fragmented plural discourses and the subjectivity of menopausal women as a continuous process (Komesaroff 1997: 61). I have woven these variables through broad feminist critiques (Leonard 1997). Through this eclectic approach I hoped to find some loose alignment between the corporeal, ontological and embodied dimensions of early menopause. The recurring themes of sexuality, fertility and subjectivity emerge through deconstructing discourses of sexual difference as immutable and non-negotiable; exposing ‘premature ovarian failure’ as a discursive construction that censures early-menopausal women; and acknowledging the discourses of individual women as unique, diverse and dynamic. I looked to a method of exposing some of these individual discourses and in Chapter Four I describe a critical research process aimed at understanding early menopause as a lived experience. In the remaining chapters I align these ontological arguments with an analysis of the discourses of women who had experienced or were experiencing an early menopause. This section partly relieves the ‘cultural non-recognition’ of the discourses of early-menopausal women. I recorded the narratives of fifty early-menopausal women through in-depth interviews and used this empirical data to direct the study. This data provides the opportunity to understand early menopause as an assortment of embodied experiences. For instance women’s experiences of age at commencement of menopause spanned over three and half decades. They did not reflect the age specifications prescribed by medical discourses. Rather women interpreted their experiences within their own discourses and determined their menopause as early based upon the expectations of their cultural context. Many of the women experienced changes attributed to menopause at midlife. It was not these changes that were significant to early-menopausal women it was how each woman translated these changes that provided meanings of early menopause. In Chapter Five I introduce the women through a table that connects the varying experiences of each woman. This profile shows that, in the main, the women’s experiences of early menopause were unexpected. I suggest that this is due to the disparity between early-menopausal women’s experiences and the current age and social norms of menopause. By bracketing the women into cohorts patterns emerged displaying differences between women who had menopause in their teens, twenties, thirties and forties. Adolescent women had intense feelings of abnormality and despair. Women who were in their twenties were less devastated by menopause than the younger women but described their sexuality and self-identity as changing. And although some women in their thirties were shocked or dismayed to have an early menopause others were ambivalent or happy. These women also described their sexuality and self-identity through changing discourses. A number of the women who were in their forties said that they were ‘too young for the menopause’ but were far less despondent than the younger women. It seemed that the greater the distance between age norms and social norms the more negatively women responded. Age norms that determine the social norms of women's lives through a ‘biological clock’ are constructed to reflect social values. But age is a social construction that changes over time. Thus it would appear that women’s changing bodies and changing discourses of early menopause are in the process of recreating age and social norms around menopause. In Chapter Six I draw upon women’s narratives that describe a connection between early menopause and sexuality. Yet the respondents were not unified in their constructions of sexuality. For instance a number of the women rejected the containment of their sexuality as absolute and defined in terms of bi-lateral hetero-sexual opposition. The discourses of these women constructed their sexuality as continuously flexible. Some early-menopausal women described this sexual mobility as an equivocal relationship between their sexuality, reproductive capacity and female organs. Other women articulated their sexuality as vacillating, ambiguous and unrepresentative of the so-called ‘true woman’. Several felt that they were not meant to have female reproductive organs at all. Nearly one third of the women had had their uterus removed at hysterectomy and the reproductive organs of two women were rudimentary. Women’s narratives showed that the social value of fertility influences constructions of early menopause. In Chapter Seven I record the contrast between the poignant responses of women who wished to have a baby of their own and other women who resisted discourses that entwine reproductivity with being a woman. For instance some women negotiated fertility through economic discourses of consumerism with the expectation that they could purchase conception as a commodity. Other women welcomed their early menopause as freedom from contraceptive concerns and others had no interest in reproduction at all. Thus discord arose through discourses that problematize early-menopausal women as non-reproductive and discourses that value variability. In addition many of the women’s accounts constructed their subjectivity as mobile, challenging the notion that discourses of the self are immutable. Chapter Eight presents narratives which suggest that the subjectivity of many women was altered continuously by early menopause. Yet some of the women rejected the construction of their subjectivity as unfluctuating. These contradictions reflect the uncertainties of the contemporary world. Nevertheless most respondents found that the tethering of menopause to constructions of midlife was incongruous with their own experiences. Many women refused to accept the label of social redundancy attached to middle-aged women. They moved their subjectivity beyond the reproductive body to a shifting and tractable identity of the self. This thesis demonstrates that the medical construction of early menopause as a rare and natural female flaw varies from women's experiences which suggest that early menopause is common and discursively constructed. This disparity has occurred through the privilege placed upon the construction of bodies as immutable and sexually static. This privileging has obscured the multi-dimensional causes of early menopause and given preference to a mono-causal theory. By exposing the variety of causes of early menopause the medical construction of women through a universal and unalterable body of reproduction is challenged. Moreover, women's discourses of early menopause demonstrate that the medical reduction of early menopause to a spontaneous bio-chemical malfunction has ignored the volatility of women’s embodied experiences. Women experience early menopause variously and through mercurial discourses. I suggest here that women's discourses of their experiences of early menopause reflect recurring and restructuring philosophical quandaries of fertility, sexuality and subjectivity. While there can be no representative claims made from this thesis it contributes to an understanding of the embodied experiences of early menopause. It provides an understanding of the creation of early menopause through social practices and goes part way to redressing the problematics of what Fraser terms ‘cultural non-recognition’. But, more importantly, it acknowledges early menopause as a variety of experiences where women interpret their changing bodies through changing discourses.

Pappadums in paradise? : journeys of Indian migrant women to Australia

The blue glass is always the hardest to find. On the beach you catch the waves bringing back the glass from forgotten tossed bottles, frosted green, clear, or mottled pale brown. But the blue glass - that's the real thing. I search for days without finding any. Sometimes there are slivers; other days, small chunks. Like a beachcomber, I comb the sands for it. I take the glass home and make some into jewellery and touchstones for people to hang on to; pour essential oils on others so the scents waft heavenward and meld together with the glass to form a bond. Words are like that. They can fuse with each other and ignite, or just quietly combine, On sunny days, I take my books with me to the beach. I toss words back and forth in my mind, like churning waves. I cobble them together, A phrase here. A sentence there. The water. The sun. The sand. The glass. The words. The paper. The Connection. I find myself enveloped in it all. The glass is from bottles tossed into the surf by unthinking people - picnickers, vacationers, those who don't have to return here and live with the remnants of their actions. Over time, the broken glass is ground and moulded by the action of the waves; the sharp edges are softened and etched by the sand and water, The sea glass is washed up on shore and picked up by beachcombers. Some recycle it for other uses like me; others just keep it as a reminder of a day at the beach. The words I sift through as I sit on the sand are measured in the sea glass. I pick each word up and look through it to see how much light shines through. What use do 1 have for it? A poem? An essay? A fragment of a sentence, for something to be said in the future? I watch the sun rest uneasily on its bed of water and slide slowly, farther down. I know the hot summer is coming to a close and I am loath to let go of the closeness I feel with nature. I live to find the blue glass, and sometimes it just happens. My search for Indian migrant women was like my quest for the blue glass. It was not an easy task. It became a process of rummaging through other people's lives, searching for fragments and relics. Eventually I was able to fit pieces together to form a mosaic of their lives in that other time, that other place. And also in this present time, in this place they now call home, Australia.

Women's silence : in the space of words and images

My thesis is made up of words and images. This study investigates the way in which silence operates productively within and between the two modes of communication. I suggest that in the process of changing words into images or scripto-visual art-practice, the silence in women's lives can be articulated. I argue that women draw on the generative qualities of silence to create forms of speech that override the cultural constructions of gender which have placed them within the space of ‘mute’ silence. To gain an historical perspective of this practice by women, I consider the lives of medieval nuns within religious enclosure and their work with words and images in the illuminated manuscript. I make a comparative study of original illuminated manuscripts, focussing mainly on visual language and locating aspects of the work closest to my own art-practice: the visual treatment of the space and inter-textual components of the page or folio. This project does not include an examination of miniatures or historiated initials. Rather, its aim is to identify and compare the use of other aesthetic devices available to the medieval scribe/artist through which they might have interacted with the text. I suggest links between verbal and visual performances of language and the repetition, or copying of texts by medieval nuns, as a means of female embodiment of words and their spaces. From the outcomes of my studio investigations and my consideration of other contemporary feminist art practices, I demonstrate how women artists may ‘re-write’ the text and ‘speak’ their silence through visual language and the acts of writing, drawing and painting the words of others. Through my engagement with feminist critical theory, the work of medieval scholars, original illuminated manuscripts and my studio research, I propose that scripto-visual practice remains particularly significant for women despite the differences between the medieval period and our own. As a generative practice, it negotiates some of the societal constraints on women's speech and visibility, because its language is ‘silent and disembodied’ from the image of woman constructed by male discourse. It is a form of speech that acknowledges as it defies the social and cultural conditions that shaped its necessity, articulating an alternative voice of women in the space of words and images.

Staff perceptions of the implementation of enterprise resource planning systems in three Australian universities

This chapter reports a study that examined the staff perceptions of the implementation of an Enterprise Resource Planning system (ERPs) in three Australian universities. The literature on issues impacting on effective Enterprise Resource Planning (ERP) implementations identified a number of issues that translate from the corporate sector to the higher education sector and included a number that require particular focus in this sector. Case study methodology is used to examine the staff perceptions of the management of ERP implementations in three Australian universities in the process of implementing ERP systems. The study was conducted in two phases. The first phase of the study obtained data through a series of focus groups at one university and, combined with an analysis of the relevant literature served as a framework for the development of the research process in the second phase of the study. This phase involved in depth interviews with staff that enabled the researcher to undertake a more detailed exploration of the staff perceptions of influences affecting ERP system implementations at three Australian universities. This chapter reports that staff perceptions of the process of ERP implementations are central to their efficacious implementations in Australian universities. Staff perceptions demonstrate that particular consideration of organisational influences related to their context and the perceptions of the users of the systems must be factored into the planning for ERP implementations in Universities.

Cognitive style as a factor in accounting students' perceptions of career choice factors

Since prior studies of individuals' perceptions of career-choice factors have not considered the effect of cognitive styles of subjects, this study, using 68 accounting students, investigated the mediating effects of the field dependent-independent cognitive dimension on perceptions of the importance of career-choice factors. The results, in general, show that cognitive style affected individuals' perceptions of career-choice factors, suggesting that future studies of individuals' perceptions should take into account individual cognitive differences.

A status report on women academic accountants in Australia

This paper reports the findings of a survey of the attributes, career satisfactions and aspirations of Australian Academic Women Accountants (AAWA). The survey sought information about personal characteristics, institutional role expectations and perceptions of gender-related issues involving recruitment, promotion and retention of AAWAs. The data provide not only an interesting insight into respondents' perceptions of a career in academic accounting, but also a comparative measure against which future progress of AAWAs can be evaluated. The paper makes suggestions for facilitating the career paths of AAWAs at both institutional and individual levels.
