One career, two identities : an assessment of gay men`s career trajectory

Most of the research on career development of sexual minorities focuses on lesbians. Gay men, on the other hand, have received little attention in the literature as it is assumed that they face fewer difficulties in career development because they are men. This paper redresses this gap by presenting an analysis of the impact of sexual identity on the career development of gay men, drawing on both a literature review of the literature on sexual identity, gay organizational studies and career development and the results of a recent interview study. In accord with other literature, the study demonstrates that gay men, like other sexual minorities, are confronted with a conflict between personal and career needs, and have to deal with society's expectations and intolerance towards homosexuality. Suggestions are given for research that will lead to a deeper understanding of the career decisions and attitudes of gay men.

Counter-revolution, order and international politics

Every social revolution has elicited some form of counter-revolutionary response from the international system. The impulse to reverse revolutionary transformation has much to tell us about the dynamics of social revolution as well as the nature of international order. The purpose of this article is to investigate the relationship between counter-revolution and international order. First it establishes a basic conceptual framework of international counter-revolution and argues that counter-revolution should be understood as more than just an active opposition to revolution and also examines the motives of counter-revolutionaries. Second, using two interpretations of the international system – those of Henry Kissinger and Raymond Aron – the article draws several conclusions about the international tendency to attempt to overturn revolution and concludes that there exist international systemic pressures, of a non-neorealist kind, which provide the basis for international order. These pressures not only produce order but, at certain times, impel states to counter radical transformations in parts of the world which seem, at first glance, to have little consequence for the functioning of international order.

Heavy metal concentrations in wild and cultured blacklip abalone (haliotis rubra Leach) from southern Australian waters

The concentrations of 12 trace metals were assessed in wild and cultured specimens of blacklip abalone, Haliotis rubra, from each of two sites, Geelong and Port Fairy, in Victoria, Australia. Cadmium, copper, iron and zinc were quantified in the foot muscle of specimens from all four populations but the concentrations of aluminium, arsenic, beryllium, chromium, lead, manganese, nickel and vanadium were below the detection limits of the instrumental techniques employed. When similar sized specimens from each population were compared, the concentrations of each of the quantifiable metals varied according to location. The Geelong wild population had the highest or equal highest concentrations of each metal. Metal concentrations in the wild populations were usually greater than or equal to the concentrations in the corresponding cultured population. The concentrations of the regulated essential elements, copper and zinc, decreased with an increase in abalone length whereas the concentrations of iron, manganese and cadmium were independent of length. Metal concentrations in H. rubra from all sites complied with the Australian Food Code and other standards of food safety.

GLBT workplace experience : the impact of social practices, oranisational context and personal factors on turnover decisions

‘Gay Rights’ have recently become a major issue in many Australian employers with the enactment of new legislation. Thus, research on employment issues for GLBT (gay/ lesbian/ bisexual/ transgendered) members of the work has attracted considerable attention from academic and researchers in recent years. However, there is still little research relating to sexual orientation in the management literature. This paper develops a model exploring the impact of potential personal and contextual factors (legal system, industry and organisational) on turnover decisions of GLBT members of the workforce. This paper also suggests a number of potential topics and methodological issues for future research.

The role of jak2a in zebrafish hematopoiesis

Janus kinase 2 (Jak2) transduces signals from hematopoietic cytokines, and a gain-of-function mutation (Jak2617V>F) is associated with myeloproliferative diseases, particularly polycythemia vera. In this study, we examined the role of jak2a in zebrafish embryos in knock-down and overexpression studies using morpholinos (MOs) targeting the 5' untranslated region (UTR) (jak2aUTR-MO) and splice-site junction (jak2aSS-MO) of jak2a, a Jak inhibitor AG490 and a constitutive-active form of jak2a (jak2aca). At 18 and 24 hours after fertilization (hpf), jak2a is expressed predominantly in the intermediate cell mass (ICM; site of primitive hematopoiesis) of wild-type and chordin morphant embryos (characterized by expansion of ICM). Both jak2a MOs and AG490 reduced gata1+ (erythroid) cells in Tg(gata1:GFP) embryos, signal transducer and activation of transcription 5 (stat5) phosphorylation, and gene expression associated with early progenitors (scl and lmo2) and erythroid (gata1, he1 and ßhe1) and myeloid (spi1 [early] and mpo [late]) lineages. The chordin morphant is associated with increased stat5 phosphorylation, and both jak2a MOs and treatment with AG490 significantly ameliorated ICM expansion and hematopoietic gene up-regulation in these embryos. Injection of plasmid encoding jak2aca significantly increased erythropoiesis and expression of gata1, he1 and ßhe1, spi1, mpo, and l-plastin. In conclusion, zebrafish jak2a is involved in primitive hematopoiesis under normal and deregulated conditions.

New early devonian charophyta from Gondwana

Early Devonian charophytes are reported from Australia (Buchan, Victoria) and Europe (Landeyran, southern France): Moellerina australica n. sp. Feist and Pinnoputamen occitanicum n. sp. Feist. Sedimentological data and associated faunas from these localities accord with both species having inhabited lacustrine or estuarine environments. A critical review of Devonian biotopes confirms that, as with present day species, Mid Palaeozoic charophytes could not have lived in open marine habitats. Originating in Baltica during the Silurian, charophytes appeared in Gondwana in the earliest Devonian.

Immunostimulatory polysaccharides from Chlorella pyrenoidosa. A new galactofuranan. Measurement of molecular weight and molecular weight dispersion by DOSY NMR.

Fractionation of the hot water extract of Chlorella pyrenoidosa was performed using a combination of ethanol precipitation, size exclusion chromatography, and anion exchange chromatography. One fraction contained a new polysaccharide, and this compound was shown to be a 1→2-linked β-d-galactofuranan from its 1D and 2D 1H and 13C NMR spectra, with a molecular weight of 15 kDa from DOSY NMR measurements. A number of other fractions were shown to have the same repeating unit as the previously identified arabinogalactan. However, arabinogalactans from different fractions were shown by DOSY NMR to have different molecular weights, which ranged from 27 to 1020 kDa. Agreement with molecular weights measured for some of these fractions by SEC-MALS was very good, further confirming the relationship established by Viel et al. between molecular weights of neutral polysaccharides and self-diffusion coefficients. The smaller molecular weight polysaccharides, the galactofuranan and the 27 and 50 kDa arabinogalactans, were shown to be close to monodisperse by analysis of the distributions of the self-diffusion coefficients for the polymers. The larger arabinogalactans had considerable variation in their molecular weights (188 ± 109 kDa and 1020 ± 370 kDa). Only the two larger arabinogalactans showed immunostimulatory activity.

Machismo and the construction of immigrant latin American masculinities

While a growing number of North American authors have researched Latin American men and masculinities within Latin America as well as the experiences of Latin American men migrating to the United States, there has been little research on the specific issues facing Latin American men in Australia. In this chapter we explore the experiences in Australia of a variety of male migrants from Latin America through three key elements which emerged through our research: the importance of men as 'providers' for the family and the place in men's sense of self; the changing nature of men's and women's roles and statuses in Australian society and their difference from Latin America; and the shifting nature of what constitutes 'home' and a sense of belonging for Latin American men. In addressing the issues that the men face, we also examine the nature of the discourses on machismo and the almost fetishised nature of its oversimplified usage in relation to Latin American men generally and in defining their identities in Australia.

Immigrant men and domestic life - renegotiating the patriarchal bargain?

In this chapter I examine domestic practices in migrant families through interviews with immigrant men who were asked to talk about the impact that migration and displacement had upon their attitudes and behaviour in relation to their gendered roles. How are their personal and domestic relationships with women affected by migration? How do they feel about any changes in gender roles and the division of domestic labour? How do they feel about the perceived and experienced changes in gendered power?

The aim of the chapter is to explore how gendered power operates within particular immigrant groups. Given that the literature argues that migration influences the relations between men and women (Shahidian 1999)" a critical examination of immigrant men's experience of masculinity may shed some light on how gender-based inequalities in migrant communities are enacted. It has already been noted in this book how little we know about the effects of migration on men's domestic relations (Hibbins and Pease in this volume). Hibbins and I have argued that immigrant men need to renegotiate their gender identity as they relate their own cultural understandings of masculinity to the meanings and practices in the dominant culture. In this chapter I explore what this process of negotiation means for immigrant men's involvement in domestic work and family life.

The application of ultrasound to dairy ultrafiltration : the influence of operating conditions

Work previously presented has shown that ultrasound can be effective in enhancing both the production and cleaning cycles of dairy membrane  processes. In this present work we extend these previous results to consider the effect of ultrasonic frequency and the use of intermittent ultrasound. These results show that the use of continuous low frequency (50 kHz) ultrasound is most effective in both the fouling and cleaning cycles. The application of intermittent high frequency (1 MHz) ultrasound is less effective. At higher transmembrane pressure, high frequency pulsed sonication can indeed lead to a reduction in steady state membrane flux. The benefits of ultrasound arise from a reduction in both concentration polarization and in the resistance provided by the more labile protein deposits that are removed during a water wash. Conversely, the loss of membrane flux when high frequency pulsed sonication is used arises from a significant increase in the more tenacious ‘irreversible’ fouling deposit.
