Strategic concealment of sexual identity in an estrildid finch

One explanation for the evolution of sexual monomorphism is the sexual indistinguishability hypothesis, which argues that in group-living species individuals might benefit by concealing their sex to reduce sexual competition. We tested this hypothesis in long-tailed finches Poephila acuticauda. Males and females could not be reliably distinguished morphologically or by analysis of the reflectance spectra (300-700 nm) from the plumage and bill. Males seemed unable to distinguish the sex of an unfamiliar individual in the absence of behavioural cues; they were equally likely to court and copulate with unfamiliar males and females but rarely courted familiar males. Here we report the first experimental evidence that sexual monomorphism enables strategic concealment of sex. Males were more likely to reveal their sex when faced with a solitary unfamiliar individual than a group of unfamiliar individuals. When encountering an unfamiliar male that revealed his sex, subordinate males were more likely to conceal their sex than dominant males.

Practising gender : the production of identity by school children

The thesis utilises ‘practice theory’ to argue that the self is not only an effect of social practices but also a technique for action and develops an alternative way of explicating and conceptualising the constitution of the self within the micro-practices of routine, everyday life. This is in contrast to a general tendency within ‘practice theory’, ‘constructionist’ and ‘discursive’ approaches towards a determinist conception of the self. The thesis explores this conceptual framework in fieldwork focussed on formation and production of gender-identity among young school children and offers a new perspective of gender-identity in the classroom. The thesis provides a fourfold contribution: (1) It provides insights into how in the classroom, children take up (conventional) gender differentiated conduct and dispositions in order to forge both their identity and the establishment of a social order based on gender. This gender order is not simply imposed on them by teachers but is actively constructed by the children. The thesis provides insights into how the children in the classroom seize and appropriate the practices of gender for their own ends. These ends, I argue, are the construction of their gender-identity, and the establishment and maintenance of a ‘matrix of intelligibility’. (2) It offers a close-up illustration of how gender construction is negotiated and contested between girls and boys. This is characterised as largely a struggle for enablement — the power to be and to do — rather than as a struggle of one gender over another. (3) It develops an analysis of classrooms as productive sites, as ‘complex strategical situations’ in which the participating agents — the teachers and students—deploy and utilise available resources in their ongoing construction of the world. This suggests that that the social world is not as unitary and totalising as ‘constraint perspectives’ within practice theory often imply. (4) It proposes methodological perspectives and strategies for researching empirically the day-to-day production of gender and for capturing that complex and often elusive process ‘in flight’. It shows the value of an ‘ascending analysis’, one that does not foreclose findings on the basis of a pre-existing theoretical position, and the rich potential of ‘flashpoints’ as a way of illuminating ongoing and often ‘unremarkable’ and therefore unnoticed practices of gender production. The theoretical terrain explored a range of theorists on the self not usually brought together, including Butler, Rose, Foucault, Giddens and Garfinkel and Schatzki. These theorists share in common the perspective that social practices rather than the agent or social totality are the ontological basis of the social world. It is argued that the self is constituted in its enactment and the thesis pursues Foucault’s (2002) question of how the self participates in its own subjectification. The empirical focus of the thesis examined the activities of children at school for insights into how they participated in the making of their gender-identity. The research addressed the questions: (1) To what extent do children construct their gender-identity and what kinds of encouragement do they receive for this? (2) To what extent did the children seem to be appropriating gender practices and inciting the making of gender-identity in the classroom? (3) To what extent can the classroom be viewed as a site of gender contestation and borderwork? Using the concept of ‘flashpoints’, — significant or poignant moments in the classroom — classroom activities were observed to catch gender-identity production ‘in flight’ and to describe how the children seize upon moments to make gender salient. Year Three children in five classrooms in two Victorian schools were observed during English communication and literacy lessons. Individual interviews with teachers in the participating schools and group interviews with the children from the classrooms were undertaken to amplify the observations. Much of the children’s behaviour can be interpreted as their efforts to make gender salient in social interactions. Gender-identity production and gender ‘border work’ (Thorne, 1993) and contestation appeared to be a major activity and preoccupation of the children, even in the face of teacher’s attempts to encourage a gender-neutral environment The children were often more active than the teachers in imposing the ‘gender agenda’ identified by Evans (1988). Overall, this thesis contributes to the development of the theory of subjectivity and identity formation. Social practices are not imposed and individuals seize upon social practices to further their own ends. It is through these routine, everyday activities that social practices are reproduced. The study provides an avenue for understanding the actions of children and the operation of gender power and border work within the classroom.

Sociology of cancer in men and women : sexuality, identity and body changes

Prostate and breast cancers are a common group of gender specific diseases that affect men and women respectively. This study explores the impact of the cancer and the social processes involved in re-establishing the self in the aftermath of cancer. The study's premise is that the self is an embodied social agent and that the body is the medium where illness is expresses and experienced by the embodied self.

Adolescent’s cultural identity and neighbourhood environment

Objective: this study aims to find out how adolescents in Australia identify themselves culturally, and how adolescents from different cultural groups differ in their assessments of their neighbourhood environments. Methods: one hundred and sixty-six adolescents in Sydney completed a self-administered questionnaire, which collected information of their neighbourhood environments and their cultural backgrounds. Results: adolescents reported a great variety (67) of different cultural backgrounds, clustered into three cultural groups: Australian cultural identity group, Heritage cultural group, and Biculturalism group. Although no significant difference was found on most neighbourhood environment factors between the cultural groups, adolescents from Heritage cultural group scored significantly lower on the factor Vegetation & Facilities. Conclusions: The results of this study suggest that the overall neighbourhood environments for adolescents from different cultural groups are satisfactory. However, ethnic minority adolecents live in neighbourhoods with less vegetation and facilities, which suggest that spatial inequity related to ethnic backgrounds still exist in Australia.

Reaping identity meanings from an agrarian past : southern harvesters of commercially cultivated regional heritage

Extending knowledge of the cultural shaping and variegating of white identity that occurs through the commercial diffusion of identity myths, we examine the reception of Southern identity myths promoted in the oppositional narratives of New South commercial media. We characterize oppositional narratives as texts which operate by eliciting an interpretive reading that devalues rather than supports the surface narrative, and explain the duplicitous text as one intended to seduce a dominant power, while empowering and bolstering identity of a marginalized group. After elaborating how oppositional discourse can serve to reinforce the identity frame constructed by regional media producers, we report on a study examining how urban and rural Southerners read and respond to this discourse. Our findings highlight mediators in the relationship between individuals’ oppositional readings and their alignment of identity in a manner responsive to it.

The use of molecular and morphological characters to resolve the taxonomic identity of cryptic species : the case of Miniopterus manavi (Chiroptera, Miniopteridae)

Based on recent molecular phylogenetic studies, the Old World bat family Miniopteridae, composed of species in the genus Miniopterus, has been shown to contain complex paraphyletic species, many of which are cryptic based on convergent morphological characters. Herein we resolve the phylogenetic relationships and taxonomy of the species complex M. manavi on Madagascar and in the Comoro Archipelago, where these animals occur in different bioclimatic zones. First using mitochondrial cytochrome-b sequence data to define clades and then morphology to corroborate the molecular data, including comparisons to type specimens, we demonstrate that animals identified as this taxon are a minimum of three species: M. manavi sensu stricto occurs in at least the central portion of the Central Highlands; M. griveaudi has a broad distribution in lowland northern and central western Madagascar and the Comoros (Anjouan and Grande Comore), and M. aelleni sp. n. has been found in northern and western Madagascar and the Comoros (Anjouan). In each case, these three clades were genetically divergent and monophyletic and the taxa are diagnosable based on different external and craniodental characters. One aspect that helped to define the systematics of this group was isolation of DNA from one of the paratypes of M. manavi collected in 1896 and new topotypic material. Miniopterus manavi is most closely allied to a recently described species, M. petersoni. At several localities, M. griveaudi and M. aelleni have been found in strict sympatry, and together with M. manavi sensu stricto show considerable convergence in morphological characters, but are not immediate sister taxa. In defining and resolving the systematics of cryptic species, such as miniopterid bats, the process of defining clades with molecular tools, segregating the specimens accordingly, and identifying corroborative morphological characters has been notably efficient.

Crossing the line : collusion or collaboration in university group work?

In both policy and practice, collusion is a perplexing area of academic integrity. Students are expected to learn to work collaboratively in university courses, yet are often required to submit assessment tasks as individuals whilst in group-work situations. This paper discusses the tension between 'collaboration' and 'collusion' in group-work and the consequences for crossing the line. Adopting a theoretical framework from Bourdieu's work (Bourdieu and Passeron, 1971; Bourdieu, 1991) on symbolic power, the notion of legitimate voice and intertextuality, this paper outlines the effects on the academic identities of 17 students found 'guilty' of collusion in one Australian university. In addition, 34 staff involved in formal disciplinary procedures were interviewed. The findings indicate that collusion is a fraught notion and not approached systematically across the university, nor with any degree of confidence by staff or students. The delineation between 'acceptable collaboration' and 'collusion' appears to be founded in shifting sands, with negative attitudes towards collaborative tasks being the main lesson learned by students.

Finding a place for personal growth in an Australian community singing group for older people

As in many countries, Australia is faced with an aging population. This creates challenges for the maintenance of well-being which can be enhanced by active engagement in society. Music engagement encompasses a range of social participation and has the potential to recognise the contribution of older people to their local communities. Engagement in music by older people (50+) is positively related to individual and community well-being.  Music participation can contribute to a better quality of life, particularly in relation to health and happiness. The possible forms of music engagement are myriad.

This paper focuses on two members of a mixed voluntary singing group formed by older residents of an outer suburban community in Melbourne, Australia.  This study frames music as a positive way for older people to find a place for personal growth and fulfilment in a singing group. This phenomenological qualitative single case study focuses on two members of a small singing ensemble, the Skylarkers, formed to perform at retirement villages, nursing homes and facilities for senior citizens. In this study, data were gathered by interviews and analysed using interpretative phenomenological analysis.

Two significant themes emerged. The first concerned the nature of the choir and its fluid membership and notions of self-identity. The second theme concerns the validation offered to individual members by active music participation through which they gained a sense of purpose, fulfilment and personal growth. This emphasis is unusual in discussions of community music engagement that ordinarily identify the importance of social connections. Groups such as the Skylarkers provide a place for members to continue their active engagement with music performance and music learning.

Maintenance of cultural identity

The aim of this qualitative study is to explore the transmission of health beliefs among three generations of Greek families in Melbourne, Australia and the way they understand both health and disease as an aspect of cultural maintenance in the context of the larger Australian society. More specifically this paper will discuss the extent to which the immigrant generation has created a memory culture and how this has affected the sense of cultural identity of the first and second generation Greek Australians. Unlike the mainstream Australian community, the Greek population has so far maintaned a traditional framework due to the importance they ascribe to both culture and traditions that have been handed down from from the immigrant generation to the first and second generation Greek Australians. However, it is not only the immigrant generation that holds on to these traditions. More and more the first and second generation Greek Australians are set on maintaining their Hellenic heritage, and many community organizations in Melbourne, Australia are now largely supported by the younger generations. The results of this study have practical applications in elucidating how the memory culture that has been created by the immigrant generation may impact this cultural group’s conceptualization of health and the potential this may have to impact the use of health care by providin insight into the role of culture in forming individual or group conceptulizations of health in this community.

National identity in fragile states: insights from tertiary students in Melanesia and Timor-Leste

The challenges of nation building in Melanesia and Timor-Leste have often been neglected in the regional focus on state-building challenges. High levels of ethno-linguistic diversity, combined with an array of regional, historical and cultural divisions, continue to present obstacles to the creation of a cohesive sense of national political community leading these nations to be labelled ‘fragile’. This paper presents the findings of a comparative study on the attitudes of tertiary students in Melanesia and Timor-Leste to national identity and nation building. A strong pan-Melanesian pattern of group identification was identified, common to Papua New Guinea, Solomon Islands and Vanuatu. The ongoing importance of traditional authority and custom in informing conceptions of political community and identity was evident in all four case study sites, but was in each case matched by indicators of respect for modern state authority. The survey also reveals some significant gender differences in key attitudes towards national identity, including the role of traditional authorities. Most importantly, the study reveals high degrees of national pride, and faith in democratic principles and citizenship; but conversely, low levels of pride in contemporary democratic performance and inter-group tolerance.

Reconciling custom, citizenship and colonial legacies: Ni-Vanuatu tertiary student attitudes to national identity

Nation-building remains a key challenge in Vanuatu. From the origins of this new nation in 1980, it was clear that creating a unifying sense of national identity and political community from multiple languages and diverse traditional cultures would be difficult. This paper presents new survey and focus group data on attitudes to national identity among tertiary students in Vanuatu. The survey identifies areas of common attitudes towards nationalism and national identity, shared by both Anglophone and Francophone Ni-Vanuatu. However, despite the weakening ties between language of education and political affiliation over recent years, the findings suggest that there remain some key areas of strong association between socio-linguistic background, and attitudes to the nation, and national identity. These findings cast new light on the attitudes of likely future elites towards regional, ethnic, intergenerational and linguistic fault lines in Vanuatu and the challenges of building a cohesive sense of political community and national identity.

Efficient escrow-free identity-based signature

The notion of identity-based signature scheme (IBS) has been proven useful in some scenarios where relying on the validity of the certificates is impractical. Nevertheless, one remaining inherent problem that hinders the adoption of this cryptographic primitive in practice is due to the key escrow problem, where the private key generator (PKG) can always impersonate the user in the system. In 2010, Yuen et al. proposed the notion of IBS that does not suffer from the key escrow problem. Nevertheless, their approach relies on the judge who will later blame the malicious PKG when such a dispute occurs, assuming that the PKG is willing to collaborate. Although the approach is attractive, but unfortunately it is impractical since the malicious PKG may just refuse to collaborate when such an incident happens. In this paper, we propose a new escrow-free IBS, which enjoys three main advantages, namely key escrow free, practical and very efficient. We present a generic intuition as well as an efficient instantiation. In our approach, there is no judge involvement required, as the public can determine the malicious behaviour of PKG when such an incident happens. Further, the signature size of our instantiation is only two group elements, which outperforms the existing constructions in the literature.
