MarcoPolo-R near earth asteroid sample return mission

MarcoPolo-R is a sample return mission to a primitive Near-Earth Asteroid (NEA) proposed in collaboration with NASA. It will rendezvous with a primitive NEA, scientifically characterize it at multiple scales,and return a unique sample to Earth unaltered by the atmospheric entry process or terrestrial weathering. MarcoPolo-R will return bulk samples (up to 2 kg) from an organic-rich binary asteroid to Earth for laboratory analyses, allowing us to: explore the origin of planetary materials and initial stages of habitable planet formation; identify and characterize the organics and volatiles in a primitive asteroid; understand the unique geomorphology, dynamics and evolution of a binaryNEA. This project is based on the previous Marco Polo mission study,which was selected for the Assessment Phase of the first round of Cosmic Vision. Its scientific rationale was highly ranked by ESA committees andit was not selected only because the estimated cost was higher than theallotted amount for an M class mission. The cost of Marco Polo-R will be reduced to within the ESA medium mission budget by collaboration withAPL (John Hopkins University) and JPL in the NASA program for coordination with ESA's Cosmic Vision Call. The baseline target is a binary asteroid (175706) 1996 FG3, which offers a very efficient operational and technical mission profile. A binary target also providesenhanced science return. The choice of this target will allow newinvestigations to be performed more easily than at a single object, andalso enables investigations of the fascinating geology and geophysics ofasteroids that are impossible at a single object. Several launch windows have been identified in the time-span 2020-2024. A number of otherpossible primitive single targets of high scientific interest have beenidentified covering a wide range of possible launch dates. The baselinemission scenario of Marco Polo-R to 1996 FG3 is as follows: a singleprimary spacecraft provided by ESA, carrying the Earth Re-entry Capsule, sample acquisition and transfer system provided by NASA, will be launched by a Soyuz-Fregat rocket from Kourou into GTO and using two space segment stages. Two similar missions with two launch windows, in 2021 and 2022 and for both sample return in 2029 (with mission durationof 7 and 8 years), have been defined. Earlier or later launches, in 2020 or 2024, also offer good opportunities. All manoeuvres are carried out by a chemical propulsion system. MarcoPolo-R takes advantage of three industrial studies completed as part of the previous Marco Polo mission (see ESA/SRE (2009)3, Marco Polo Yellow Book) and of the expertise of the consortium led by Dr. A.F. Cheng (PI of the NASA NEAR Shoemaker mission) of the JHU-APL, including JPL, NASA ARC, NASA LaRC, and MIT.

«Le grand retour» : le processus de rapatriement chez l’étudiant en échange à l’international

L’augmentation rapide de l’interdépendance mondiale, provoquée par le développement de la mondialisation, exige une redéfinition de la notion traditionnelle de l’éducation supérieure. Au Canada, comme dans le reste du monde, plusieurs universitaires, fonctionnaires du gouvernement et étudiants insistent maintenant sur l’intégration de l’internationalisation dans l’éducation supérieure à travers des échanges interculturels et des études à l’étranger, dans l’espoir que les générations canadiennes à venir développent une perspective globale et deviennent des « citoyens du monde » (Comité consultatif sur la stratégie du Canada en matière d’éducation internationale, 2012). Pourtant, pour garantir que l’étudiant qui participe à un échange profite le plus de son expérience internationale, nous devrons comprendre comment une telle expérience l’influence tant à court terme qu’à long terme. Bien que d’autres études se soient concentrées sur le court terme (le séjour à l’étranger et ses impacts immédiats), peu ont examiné le retour de l’étudiant, sa réintégration dans sa société d’origine et les effets subséquents à long terme, tels que les développements personnels qui pourraient suivre le rapatriement. Cette étude qualitative examine les témoignages de huit étudiants au premier cycle de l’Université de Montréal sur la façon dont ils ont vécu leur rapatriement à Montréal après un échange pédagogique à l’étranger. Quoique certains chercheurs présentent la notion de rapatriement comme une série d’événements déconnectés, notre analyse fait ressortir une tendance similaire dans tous nos témoignages qui nous permet dorénavant de considérer ce rapatriement comme un processus en trois étapes interconnectées. En empruntant à la théorie Intercultural Personhood de Kim (2008), nous sommes désormais en mesure de qualifier ces trois étapes comme étant le stress, l’adaptation et l’évolution. Non seulement cette interprétation nous aide à mieux comprendre les difficultés rencontrées par l’étudiant à l’occasion de son retour, mais elle facilite également l’identification des transformations identitaires qui apparaissent à ce moment-là et la manière dont ces transformations influencent le processus de rapatriement.

Spectrum simulation of rough and nanostructured targets from their 2D and 3D image by Monte Carlo methods

Corteo is a program that implements Monte Carlo (MC) method to simulate ion beam analysis (IBA) spectra of several techniques by following the ions trajectory until a sufficiently large fraction of them reach the detector to generate a spectrum. Hence, it fully accounts for effects such as multiple scattering (MS). Here, a version of Corteo is presented where the target can be a 2D or 3D image. This image can be derived from micrographs where the different compounds are identified, therefore bringing extra information into the solution of an IBA spectrum, and potentially significantly constraining the solution. The image intrinsically includes many details such as the actual surface or interfacial roughness, or actual nanostructures shape and distribution. This can for example lead to the unambiguous identification of structures stoichiometry in a layer, or at least to better constraints on their composition. Because MC computes in details the trajectory of the ions, it simulates accurately many of its aspects such as ions coming back into the target after leaving it (re-entry), as well as going through a variety of nanostructures shapes and orientations. We show how, for example, as the ions angle of incidence becomes shallower than the inclination distribution of a rough surface, this process tends to make the effective roughness smaller in a comparable 1D simulation (i.e. narrower thickness distribution in a comparable slab simulation). Also, in ordered nanostructures, target re-entry can lead to replications of a peak in a spectrum. In addition, bitmap description of the target can be used to simulate depth profiles such as those resulting from ion implantation, diffusion, and intermixing. Other improvements to Corteo include the possibility to interpolate the cross-section in angle-energy tables, and the generation of energy-depth maps.

Transport and distribution of lindane and simazine in a riverine environment: measurements in bed sediments and modelling

Aquatic sediments often remove hydrophobic contaminants from fresh waters. The subsequent distribution and concentration of contaminants in bed sediments determines their effect on benthic organisms and the risk of re-entry into the water and/or leaching to groundwater. This study examines the transport of simazine and lindane in aquatic bed sediments with the aim of understanding the processes that determine their depth distribution. Experiments in flume channels (water flow of 10 cm s(-1)) determined the persistence of the compounds in the absence of sediment with (a) de-ionised water and (b) a solution that had been in contact with river sediment. In further experiments with river bed sediments in light and dark conditions, measurements were made of the concentration of the compounds in the overlying water and the development of bacterial/algal biofilms and bioturbation activity. At the end of the experiments, concentrations in sediments and associated pore waters were determined in sections of the sediment at 1 mm resolution down to 5 mm and then at 10 mm resolution to 50 mm depth and these distributions analysed using a sorption-diffusion-degradation model. The fine resolution in the depth profile permitted the detection of a maximum in the concentration of the compounds in the pore water near the surface, whereas concentrations in the sediment increased to a maximum at the surface itself. Experimental distribution coefficients determined from the pore water and sediment concentrations indicated a gradient with depth that was partly explained by an increase in organic matter content and specific surface area of the solids near the interface. The modelling showed that degradation of lindane within the sediment was necessary to explain the concentration profiles, with the optimum agreement between the measured and theoretical profiles obtained with differential degradation in the oxic and anoxic zones. The compounds penetrated to a depth of 40-50 rum over a period of 42 days. (C) 2004 Society of Chemical Industry.

”Tacksamhet för att jag fick ett nytt liv” : En kvalitativ studie om återanpassningsstrategier efter avtjänat fängelsestraff

Intresset för kriminalitet och individerna bakom de kriminella handlingarna ökar i samhället och återges i media dagligen. Det är just individen bakom brottet, hen som fängslas och får avtjäna sitt straff som denna studie riktar sitt fokus på. När fängelsegrindarna öppnas och återinträdet till samhället blir ett faktum; Hur tar då dessa individer sig tillbaka till samhället för att åter bli en del av det? Syftet med denna studie är att undersöka vilka återanpassningsstrategier som frigivna använder sig av samt hur samhällets bemötande påverkar strategierna. Studien baseras på självbiografier skrivna av fyra författare som alla levt ett kriminellt liv och som sedermera avtjänat ett eller flera fängelsestraff. Resultatet visar att det finns flera anpassningsstrategier som tas i bruk. Däribland att söka hjälp och stöd hos familj, vänner eller andra sociala grupper. Vidare återfinns det i strävan efter en ”ny identitet” vilket ofta sker med hjälp av tro. Att sysselsätta sig, ge något tillbaka till samhället, visa sin kreativitet i syfte att återfå sin kredibilitet kan ses som strategier som leder fram till det slutliga målet, kredibiliteten. Slutligen kunde ett samband mellan samhällets bemötande och återanpassningsstrategierna utrönas. Ju mer negativt bemötandet är desto fler återanpassningsstrategier behövs och arbetet för att uppnå dem blir mer krävande. Givet blir då att ett bemötande som fyllts av uppmuntran till individens förändring medför att färre strategier behövs och risken för återfall blir mindre.

Early induction of chalpains in rotenone-mediated neuronal apoptosis

Rotenone is an inhibitor of mitochondrial complex I that produces a model of Parkinson's disease (PD), where neurons undergo apoptosis by caspase-dependent and/or caspase-independent pathways. Inhibition of calpains has recently been shown to attenuate neuronal apoptosis. This study aims to establish for the first time, the time-point of calpain activation with respect to the caspase activation and the possibility of cell cycle re-entry in rotenone-mediated cell death. Immunoblot results revealed calpain activation occurred at 5, 10 h prior to caspase-3 activation (at 15 h), suggesting calpain activation was an earlier cellular event compared to caspase activation in the rotenone-mediated apoptosis. In addition, an upregulation of phospho-p53 was observed at 21 h. However, no expression or upregulation of cell cycle regulatory proteins including cdc25a, cyclin-D1 and cyclin-D3 were observed, strongly suggesting that cell cycle re-entry did not occur. These findings provide new insights into the differential patterns of calpain and caspase activation that result from rotenone poisoning and which may be relevant to the therapeutic management of PD.

UnitingCare West Outreach Services and the Good Lives Model of offender rehabiliation

UnitingCare West is a not-for-profit community services organisation committed to achieving justice, hope and opportunity for all, and works to support and empower in particular those most in need in the WA community. Through its program Outreach Services, it delivers a specialist re-entry service for sex offenders and men serving life and indeterminate sentences. The program has recently been reviewed by Dr Andrew Day from the Centre for Offender Reintegration, Deakin University with input from Dr Tony Ward, University of Victoria, Wellington, New Zealand. In this paper we describe the aims of the review, the process and findings and our ongoing work in developing a rationale for the service that is underpinned by the Good Lives Model (GLM) of offender rehabilitation. More generally, the presentation will seek to understand the needs of offenders who re-enter the community following long-term imprisonment in relation to those areas of need identified in the GLM.

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.

Striving for a good life : the good lives model applied to released child molesters

The good lives model (GLM) is a strengths-based approach to offender rehabilitation in which treatment aims to equip offenders with the skills and resources necessary to satisfy primary goods, or basic human values, in personally meaningful and socially acceptable ways. The aim of the present research was to explore the practical utility of the GLM with a sample of released child molesters, and investigate the relationship between primary goods attainment and overall re-entry conditions (in terms of accommodation, social support and employment). Semi-structured interviews were conducted with 16 child molesters at one, three and six months following their release from prison. As expected, participants endorsed the majority of GLM primary goods with high importance, and positive re-entry experiences were associated with increased goods attainment. Implications for clinicians, policy makers and society as a whole are discussed.

The impact of religious diversity and revitalization on inter-religious education for citizenship and human rights

The unanticipated rise of religious diversity and the re-entry of religion to the public sphere have radically increased the need and demand for education about religions – how they contribute to social and cultural capital – and about the management of religious diversity. The global movement of people and cultures has brought religious diversity to nearly every major city. With diversity has come a renewed interest in the religious identity of others and how to incorporate religious diversity in ways that produce social cohesion. Religious diversity has also raised interest in a values discourse where once atheistic secularity prevailed, made faith-based social and health service delivery both more appealing to governments and more difficult to deliver, and has challenged societies to accommodate a wider range of religious needs and lifestyles. Policies designed to promote social justice and peace have little chance of success without taking seriously the religious dimensions to the issues involved. This context makes clear the need for opportunities to learn about the religions in a society at all levels of education – opportunities that include direct experience of the ‘other’, curricula that appreciate the worlds of faith, spirituality and religion rather than demeaning them, education that provides both historical depth and local reality. Some of this education will be in school, some in remedial work required for a generation or two of leaders who have been raised in ignorance of religion, or trained to despise it.

The science of our own fiction : affective experiments enacted through creative research

This paper will explore the ways in which art may be understood as an ongoing experiment that interacts with the plasticity of the body to prompt change and affect the body-environment relationship. The arts offer an approach to research that recognizes the importance of the affect in studies of perception and action, self-organization and selection. An affective approach to experimentation would connect cognitive activity to the material processes of the environment in a science of our own fiction. This connection becomes the basis of affective experiments, which aim to yield new insights by merging the creative researcher with self-affecting-experimenter. To this end, I will discuss the scientific objectives of the “rubber hand”, and the ‘mirror-box” experiments are contrasted with work by artists-turned-architects Arakawa and Gins and three of my creative projects to suggest how creative research might enact embodied change. Throughout the paper I will argue that cognitive processes such as attention, selection, decision and judgment are ripe for re-entry and experimentation through an embodied approach to acquiring knowledge that is particular to the arts.

Demographic differences in public attitudes towards sex offenders

Emotionally fueled public responses to news of released sex offenders have the potential to jeopardize the re-entry process, for example, hindering access to stable housing and employment opportunities. Influencing change in public attitudes towards sex offenders so that they are conducive to successful community re-entry is important in efforts to prevent recidivism. Maximizing the effectiveness of attempts to change public attitudes first requires identifying whether specific demographic groups are more prone to negative attitudes, so that attempts to change attitudes can be appropriately targeted. In the present study, 401 community members completed an online questionnaire designed to assess the affective, cognitive and behavioral dimensions of attitudes towards sex offenders. Differences in attitudes towards sex offenders based on respondent sex, age, educational attainment, occupation, parental status and familiarity with victims and perpetrators of sexual assault were investigated. Females demonstrated more-negative attitudes on affective and behavioral measures compared with males, and respondents with low levels of educational attainment demonstrated more-negative attitudes than respondents with higher levels of educational attainment on cognitive and behavioral measures; however, all groups demonstrated negative attitudes towards sex offenders to some extent. Implications for community-level interventions that promote effective re-entry, and hence reduce the likelihood of sexual reoffending are discussed.

Construction pathway : attracting the missing students and workers to university

The Commonwealth Government has the increased participation of under-represented groups to a 20% diversity target for Australian universities. It also has minimum targets of 40% of all Australians (25-34 years) holding a Bachelor’s degree by 2020. These targets are baseline items in a government agenda of improving educational outcomes for Australians and pivotal in addressing skill shortages in industries such as construction. In construction there is a skewing of skill shortages to the higher order or post entry level skills. Demand for higher skilled occupations such as construction managers, outstrips demand for construction trades (DEEWR, 2010). But whilst 41% of the industry have VET qualifications, only 10% possess HE qualifications in construction. Movement between the VET and HE sectors is low: of all construction students qualifying at AQF 4, less than 10% continue on to higher education and less than 1% of VET qualified persons in the construction workforce seek re-entry to university. This paper examines national data in construction education pathways and evaluates, using the DEMO matrix, the enablers in pathways to HE qualifications. The evaluation is based upon survey responses of two cohorts entering higher education from non-traditional pathways- articulating VET students and mature-aged workers. The results indicate that pathway programmes into construction degrees can attract non-traditional cohorts, but elements such as learner engagement, confidence, people-rich resources and collaboration are critical features of successful pathways.

Restructuring Justice: Moving Towards Gender-Responsive Programming and Alternatives to Incarceration for Non-Violent Female Offenders

The United States¿ Federal and State laws differentiate between acceptable (or, legal) and unacceptable (illegal) behavior by prescribing restrictive punishment to citizens and/or groups that violate these established rules. These regulations are written to treat every person equally and to fairly serve justice; furthermore, the sanctions placed on offenders seek to reform illegal behavior through limitations on freedoms and rehabilitative programs. Despite the effort to treat all offenders fairly regardless of social identity categories (e.g., sex, race, ethnicity, socioeconomic status, age, ability, and gender and sexual orientation) and to humanely eliminate illegal behavior, the American penal system perpetuates de facto discrimination against a multitude of peoples. Furthermore, soaring recidivism rates caused by unsuccessful re-entry of incarcerated offenders puts economic stress on Federal and State budgets. For these reasons, offenders, policy-makers, and law-abiding citizens should all have a vested interest in reforming the prison system. This thesis focuses on the failure of the United States corrections system to adequately address the gender-specific needs of non-violent female offenders. Several factors contribute to the gender-specific discrimination that women experience in the criminal justice system: 1) Trends in female criminality that skew women¿s crime towards drug-related crimes, prostitution, and property offenses; 2) Mandatory minimum sentences for drug crimes that are disproportionate to the crime committed; 3) So-called ¿gender-neutral¿ educational, vocational, substance abuse, and mental health programming that intends to equally rehabilitate men and women, but in fact favors men; and 4) The isolating nature of prison structures that inhibits smooth re-entry into society. I argue that a shift in the placement and treatment of non-violent female offenders is necessary for effective rehabilitation and for reducing recidivism rates. The first component of this shift is the design and implementation of gender- responsive treatment (GRT) rather than gender-neutral approaches in rehabilitative programming. The second shift is the utilization of alternatives to incarceration, which provide both more humane treatment of offenders and smoother reintegration to society. Drawing on recent scholarship, information from prison advocacy organizations, and research with men in an alternative program, I provide a critical analysis of current policies and alternative programs, and suggest several proposals for future gender- responsive programs in prisons and in place of incarceration. I argue that the expansion of gender-responsive programming and alternatives to incarceration respond to the marginalization of female offenders, address concerns about the financial sustainability of the United States criminal justice system, and tackle high recidivism rates.
