Carboniferous brachiopods from the "Levipustula Fauna" in central-western Argentina : biostratigraphic, palaeoclimatic, and palaeobiogeographic implications

The “Levipustula fauna” is a relatively diverse fossil assemblage composed of brachiopods, bivalves, bryozoans, gastropods and crinoids that appears in glaciomarine sequences related to the Carboniferous glacial event that affected the central-western Argentinean basins. Brachiopods that characterize this fauna have been studied in some of the classical localities of the Argentine Precordillera in San Juan province.

In the Hoyada Verde Formation, the “Levipustula fauna” is usually located immediately above the glacial diamictite horizons and appears to be associated with the mudstones facies of the postglacial transgression. From a palaeoecological study, three brachiopod subfaunas are distinguished in this formation: the lower “Neospirifer” (“Trigonotretidae” gen. nov.) subfauna, above which the more diversified Kitakamithyris subfauna occurs, and the upper Levipustula subfauna, with the dominant species being attributed to Levipustula levis Maxwell. The Hoyada Verde fauna, as well those identified in the La Capilla Formation (Cerro El Morado locality), have been proposed as the typical “Levipustula fauna”. However, in the Leoncito Formation, the “Levipustula fauna” occurs in sandstones horizons located below the glacial diamictite beds. This fauna is poorly diversified and the brachiopods are characterized by “Neospirifer” (“Trigonotretidae” gen. nov.)-Septosyringothyris assemblage and Levipustula is not abundant. This fauna has been considered a colder “pre-interglacial fauna”.

The significant taxonomic, palaeoecologic and taphonomic variations of the “Levipustula fauna”, as well as its position in the glacial sequences, suggest an important palaeoenvironmental control related to Carboniferous glacial dynamics. From the palaeobiogeographic viewpoint, this fauna shows the highest affinity with the Eastern Australian basins from where it was previously described.

Mobility as ‘becoming’ : a Bourdieuian analysis of the factors shaping international student mobility

This paper unpacks the meanings and implications of the mobility of international students in vocational education – an under-researched group in the field of international education. This four-year study found that transnational mobility is regarded as a resourceful vehicle to help international students ‘become’ the kind of person they want to be. The paper justifies the value of re-conceptualising student mobility as a process of ‘becoming’. Mobility as ‘becoming’ encompasses students’ aspirations for educational, social, personal and professional development. Theorising mobility as ‘becoming’ captures international students’ lived realities and has the potential to facilitate the re-imagining of international student mobility with new outlooks. By theorising mobility as ‘becoming’, this research suggests the importance of drawing on the integrated and transformative nature of Bourdieu’s forms of capital in understanding the logics and practice of the social field – international student mobility.

International students in transnational mobility: intercultural connectedness with domestic and international peers, institutions and the wider community

International students’ connectedness with their peers, institutions and the broader community significantly affects their learning and wellbeing. It is important to understand their multiple desires for intercultural connectedness in order to nurture it. This paper analyses the motives and nature of international students’ intercultural connectedness. It is based on a study that includes more than 150 interviews and fieldwork with international students and staff from 25 vocational education colleges in Australia. Drawing on Blumer’s symbolic interactionism theory as a conceptual framework, the study found international students’ motivation to engage in intercultural connectedness is linked to not only their desire for respect and recognition for intellectual, cultural and linguistic capacities and diversities but also for employment aspirations. The research shows various dimensions in which intercultural engagement is seen to encompass not only empathy, sociability and equity but also employability. The findings suggest meaningful interaction is essentially bound to reciprocal learning.

‘Get foot in the door’: International students' perceptions of work integrated learning

Work-integrated learning (WIL) is regarded as an important vehicle to assist students’ development of relevant professional skills, knowledge and attributes that can enhance their employability. WIL arrangement for international students is a challenging issue for institutions, international students themselves as well as other related stakeholders. While there is an emerging body of literature that examines WIL for international students, how the value of WIL is perceived by this cohort is little known. This paper responds to this dearth of the literature by exploring the different meanings that international students in the vocational education and training sector attach to WIL. Using Bourdieu’s thinking tools of capitals and habitus to interpret interview data from 105 international students, this paper shows that WIL is seen to not only add value to student learning, career aspiration and employability but also transform and enhance their symbolic and social capitals. The paper underscores the instrumental, symbolic and developmental meanings that international students associate with WIL. In particular, it highlights the reciprocal relationship between students’ development of vocational ‘being’ and personal ‘being’ through WIL.

‘I’m not like that, why treat me the same way?’ The impact of stereotyping international students on their learning, employability and connectedness with the workplace

A significant body of literature on international education examines the experiences of international students in the host country. There is however a critical lack of empirical work that investigates the dynamic and complex positioning of international students within the current education-migration nexus that prevails international education in countries such as Australia, Canada and the UK. This paper addresses an important but under-researched area of the education-migration landscape by examining how the stereotyping of students as mere ‘migration hunters’ may impact their study and work experiences. It draws on a four-year research project funded by the Australian Research Council that includes more than 150 interviews and fieldwork in the Australian vocational education context. Positioning theory is used as a conceptual framework to analyse how generalising international students as ‘mere migration hunters’ has led to the disconnectedness, vulnerability and marginalization of the group of international students participating in this research.

The international legal status of the Vatican/Holy See complex

This article offers a re-examination of the international legal status of what is here termed the Vatican/Holy See complex (VHS), focusing on claims to statehood. The problematic ‘effect’ of Vatican City, of the Holy See, of the papacy and of associated entities is interrogated at the level of international law, entering as little as possible into administrative or theological distinctions. The various grounds cited as supporting status amounting to statehood are argued to be inadequate. The continuing exchange of representatives with states by the VHS is missionary and hierarchical in character and is reflective neither of the reciprocity of peers nor of customary obligation going to law. Agreements entered into by the papacy with the Kingdom of Italy (the Lateran Pacts) in 1929, relating to the status of the geographical territory known as Vatican City, cannot be determinative of international status. Nor can membership of international agreements and organizations confer a status amounting to statehood. Events and practices since 1929 have not substantially altered international status as of 1870. The Roman Catholic Church is but one of many faith-based international movements, and since the eclipse of the papal state nearly one-and-a-half centuries ago, the status in international law of its temporal headquarters in Rome should not be privileged.
