Building a new life in Australia: introducing the longitudinal study of humanitarian migrants

Introduces a study aimed to shed light on the settlement pathways and outcomes of newly arrived humanitarian migrants, focusing particularly on the factors that promote or hinder a successful transition. Introduction Building a New Life in Australia: The Longitudinal Study of Humanitarian Migrants is a newly initiated study that aims to better understand the factors that aid or hinder the successful settlement of humanitarian migrants in Australia, and to provide an evidence base to inform policy and program development. This ground-breaking longitudinal study will employ annual data collections over five years to trace the settlement journey of humanitarian migrants from their arrival in Australia through to their eligibility for citizenship. All study participants have received a permanent humanitarian visa enabling them to settle in Australia, granted either before their arrival in Australia as part of Australia\u27s refugee program, or since their arrival, through Australia\u27s asylum seeker humanitarian program. Study participants have come from a diverse range of backgrounds and a multitude of migration pathways. Three broad research questions guide the study: What are the settlement outcomes of humanitarian migrants? How are they faring in terms of their English language proficiency, housing circumstances, labour force participation, use of qualifications, income, physical and mental health, community engagement, citizenship and level of satisfaction with life in Australia? How does access to and use of government and non-government services and welfare benefits contribute to humanitarian migrants\u27 successful settlement? Do the settlement experiences and outcomes of humanitarian migrants vary according to the differing migration pathways taken? The Australian Institute of Family Studies (AIFS) has been commissioned by the Department of Immigration and Border Protection (DIBP) (formerly the Department of Immigration and Citizenship [DIAC]) to undertake and manage the project. Colmar Brunton Social Research, in conjunction with Multicultural Marketing and Management, is the fieldwork agency undertaking the data collection for the project. From April 2014, responsibility for the study moved from the DIBP to the Department of Social Services

Secular evolution of a satellite by tidal effect. Application to Triton

Some of the satellites in the Solar System, including the Moon, appear to have been captured from heliocentric orbits at some point in their past, and then have evolved to the present configurations. The exact process of how this trapping occurred is unknown, but the dissociation of a planetesimal binary in the gravitational field of the planet, gas drag, or a massive collision seem to be the best candidates. However, all these mechanisms leave the satellites in elliptical orbits that need to be damped to the present almost circular ones. Here we give a complete description of the secular tidal evolution of a satellite just after entering a bounding state with the planet. In particular, we take into account the spin evolution of the satellite, which has often been assumed synchronous in previous studies. We apply our model to Triton and successfully explain some geophysical properties of this satellite, as well as the main dynamical features observed for the Neptunian system.Comment: 4 pages, 1 figur

A refurbished convergent point method for finding moving groups in the Hipparcos Catalogue

The Hipparcos data allow a major step forward in the research of `moving groups' in the Solar neighbourhood, as the common motion of group members causes converging proper motions. Previous knowledge on these coherent structures in velocity space has always been limited by the availability, reliability, and accuracy of ground-based proper motion measurements. A refurbishment of Jones' convergent point method is presented which takes full advantage of the quality of the Hipparcos data. The original implementation of this method determines the maximum likelihood convergent point on a grid on the sky and simultaneously selects group members from a given set of stars with positions and proper motions. The refurbished procedure takes into account the full covariance matrix of the Hipparcos measurements instead of standard errors only, allows for internal motions of the stars, and replaces the grid-based approach by a direct minimization. The method is tested on Monte Carlo simulations of moving groups, and applied to the Hyades. Despite the limited amount of data used by the convergent point method, the results for stars in and around the cluster- centre region agree very well with those of the recent comprehensive study by Perryman et al. (1998).Comment: 14 pages, 7 Postscript figures, LaTeX using mn.sty and psfig.sty; accepted for publication in MNRA

Atmospheric neutrino flux supported by recent muon experiments

We present a new one-dimensional calculation of low and intermediate energy atmospheric muon and neutrino fluxes, using up-to-date data on primary cosmic rays and hadronic interactions. We study several sources of uncertainties relevant to our calculations. A comparison with the muon fluxes and charge ratios measured in several modern balloon-borne experiments suggests that the atmospheric neutrino flux is essentially lower than one used for the standard analyses of the sub-GeV and multi-GeV neutrino induced events in underground detectors.Comment: 23 pages, 7 figures, 2 tables.

Colossal Magnetoresistance is a Griffiths Singularity

It is now widely accepted that the magnetic transition in doped manganites that show large magnetoresistance is a type of percolation effect. This paper demonstrates that the transition should be viewed in the context of the Griffiths phase that arises when disorder suppresses a magnetic transition. This approach explains unusual aspects of susceptibility and heat capacity data from a single crystal of La$_{0.7}$Ca$_{0.3}$MnO$_{3}.$Comment: 4 page

A Transgenic Marker for Newly Born Granule Cells in Dentate Gyrus

Neurogenesis in the dentate gyrus continues into adulthood, yet little is known about the function of newly born neurons or how they integrate into an existing network of mature neurons. We made transgenic mice that selectively and transiently express enhanced green fluorescent protein (EGFP) in newly born granule cells of the dentate gyrus under the transcriptional control of proopiomelanocortin (POMC) genomic sequences. Analysis of transgenic pedigrees with truncation or deletion mutations indicated that EGFP expression in the dentate gyrus required cryptic POMC promoter regions dispensable for arcuate hypothalamic or pituitary expression. Unlike arcuate neurons, dentate granule cells did not express the endogenous POMC gene. EGFP-positive neurons had immature properties, including short spineless dendrites and small action potentials. Colocalization with bromodeoxyuridine indicated that EGFP-labeled granule cells were 2 weeks postmitotic. EGFP-labeled cells expressed markers for immature granule cells but not the glial marker GFAP. The number of EGFP-labeled neurons declined with age and increased with exercise, paralleling neurogenesis. Our results indicate that POMC-EGFP marks immature granule cells and that adult-generated granule cells integrate quite slowly into the hippocampal circuitry

What makes you not a Buddhist? : a preliminary mapping of values

This study sets out to establish which Buddhist values contrasted with or were shared by adolescents from a non-Buddhist population. A survey of attitude toward a variety of Buddhist values was fielded in a sample of 352 non-Buddhist schoolchildren aged between 13 and 15 in London. Buddhist values where attitudes were least positive concerned the worth of being a monk/nun or meditating, offering candles & incense on the Buddhist shrine, friendship on Sangha Day, avoiding drinking alcohol, seeing the world as empty or impermanent and Nirvana as the ultimate peace. Buddhist values most closely shared by non-Buddhists concerned the Law of Karma, calming the mind, respecting those deserving of respect, subjectivity of happiness, welfare work, looking after parents in old age and compassion to cuddly animals. Further significant differences of attitude toward Buddhism were found in partial correlations with the independent variables of sex, age and religious affiliation. Correlation patterns paralleled those previously described in theistic religions. Findings are applied to spiritual, moral, social and cultural development and for the teaching of religious to pupils of no faith adherence. The study recommends that quantitative psychometrics employed to conceptualize Buddhist values by discriminant validity in this study could be extended usefully to other aspects of the study of Buddhism, particularly in quest of validity in the conceptualization of Buddhist identity within specifically Buddhist populations
