Difficult knowledge and uncomfortable pedagogies : student perceptions and experiences of teaching and learning in critical indigenous Australian studies
University of Technology Sydney. Faculty of Arts and Social Sciences.This research presents a grounded interrogation of studentsâ perceptions and experiences of teaching and learning in two mandatory stand-alone Critical Indigenous Australian Studies subjects at an Australian university. The study proffers rare empirical insight into the student experience of teaching and learning about colonialism, racism, whiteness and privilege. It contributes to building a better understanding of the complexities, opportunities, challenges and risks of four specific pedagogical approaches: critical anticolonialism, critical race theory, critical whiteness and intersectional privilege studies. The research was conducted by way of a critical ethnographic process involving in-depth interviews with students and teachers, focus group discussions with students and classroom observations. The research design was built on critical social constructionist foundations informed by poststructural and critical hermeneutical theoretical perspectives.
The study produced two key findings. The first is that learning in Critical Indigenous Australian Studies is inherently affective. Affectivity plays a determinant role in the opportunities, challenges and risks of teaching about colonialism, racism, whiteness and privilege. This finding signposts the need to take into serious consideration the emotionally onerous task of teaching and learning in Critical Indigenous Australian Studies and the need for compassionate pedagogical approaches and strategies that can productively navigate and manage affectivity. The second key finding is that if Critical Indigenous Australian Studies is to inspire and motivate students to act for social justice and social change, teaching and learning must focus equally on both the âknow-whatâ and the âknow-howâ. Knowing what the urgent matters are without the cultivation of practical skills to engage in social change action falls short of meeting teaching and learning objectives. A dedicated and substantive focus on cultivating practical social change skills such as discursive counter-narrative skills is a pedagogical pathway toward empowering, inspiring and motivating students to act for social change
Alternance travail-études : les effets des stages dans la formation professionnelle des élÚves
Cet article traite des effets des stages pour les Ă©lĂšves de quatre programmes professionnels offerts en alternance travail-Ă©tudes en sâappuyant sur les tĂ©moignages des Ă©lĂšves, de leurs enseignants et de leurs tuteurs en entreprise. Les expĂ©riences de stage sont dâabord regroupĂ©es dans le modĂšle traditionnel ou le modĂšle expĂ©rientiel de la typologie de lâexpĂ©rience de travail. Ensuite, les effets se diffĂ©rencient en six catĂ©gories : apprentissages Ă lâĂ©cole et en entreprise, prĂ©paration au marchĂ© du travail, socialisation professionnelle, apprentissage technique, dĂ©veloppement personnel et orientation professionnelle. La discussion et la conclusion permettent de dĂ©gager quelques conditions stimulant ou limitant lâapprentissage des Ă©lĂšves.This article uses the views of students and their teachers and workplace tutors to examine the effects of internships for students in four vocational education programs offered on an alternating work-study basis. First, studentsâ internship experiences are grouped together according to the traditional or experiential models of the work experience typology. Then, the effects of internships are differentiated according to six categories : learning at school and in the workplace ; preparation for the job market ; professional socialization ; technical apprenticeship ; personal development ; and career direction. The discussion and the conclusion identify a number of conditions that either stimulate or hamper studentsâ learning.Este artĂculo trata de los efectos de las prĂĄcticas para los alumnos de cuatro programas profesionales impartidos de manera a alternar trabajo-estudios, fundamentĂĄndose sobre los testimonios de alumnos, de sus profesores y de sus tutores en la empresa. En primer lugar, las experiencias de prĂĄcticas estĂĄn agrupadas segĂșn el modelo tradicional o el modelo experiencial de la tipologĂa de la experiencia laboral. Luego, se separan los efectos en seis categorĂas : aprendizajes en la escuela y en la empresa, preparaciĂłn al mercado laboral, socializaciĂłn profesional, aprendizaje tĂ©cnico, desarrollo personal y orientaciĂłn profesional. La discusiĂłn y la conclusiĂłn permiten destacar algunas condiciones que fomentan o limitan el aprendizaje de los alumnos

Redshift distributions of galaxies in the Dark Energy Survey Science Verification shear catalogue and implications for weak lensing
We present photometric redshift estimates for galaxies used in the weak lensing analysis of the Dark Energy Survey Science Verification (DES SV) data. Four model- or machine learning-based photometric redshift methodsâANNZ2, BPZ calibrated against BCC-Ufig simulations, SKYNET, and TPZâare analyzed. For training, calibration, and testing of these methods, we construct a catalogue of spectroscopically confirmed galaxies matched against DES SV data. The performance of the methods is evaluated against the matched spectroscopic catalogue, focusing on metrics relevant for weak lensing analyses, with additional validation against COSMOS photo-zâs. From the galaxies in the DES SV shear catalogue, which have mean redshift 0.72 0.01 over the range 0.3 < z < 1.3, we construct three tomographic bins with means of z ÂŒ f0.45; 0.67; 1.00g. These bins each have systematic uncertainties ÎŽz âČ 0.05 in the mean of the fiducial SKYNET photo-z nĂ°zĂ. We propagate the errors in the redshift distributions through to their impact on cosmological parameters estimated with cosmic shear, and find that they cause shifts in the value of Ï8 of approximately 3%. This shift is within the one sigma statistical errors on Ï8 for the DES SV shear catalogue. We further study the potential impact of systematic differences on the critical surface density, ÎŁcrit, finding levels of bias safely less than the statistical power of DES SV data. We recommend a final Gaussian prior for the photo-z bias in the mean of nĂ°zĂ of width 0.05 for each of the three tomographic bins, and show that this is a sufficient bias model for the corresponding cosmology analysis
The Dark Energy Survey : more than dark energy â an overview
This overview paper describes the legacy prospect and discovery potential of the Dark Energy Survey (DES) beyond cosmological studies, illustrating it with examples from the DES early data. DES is using a wide-field camera (DECam) on the 4 m Blanco Telescope in Chile to image 5000 sq deg of the sky in five filters (grizY). By its completion, the survey is expected to have generated a catalogue of 300 million galaxies with photometric redshifts and 100 million stars. In addition, a time-domain survey search over 27 sq deg is expected to yield a sample of thousands of Type Ia supernovae and other transients. The main goals of DES are to characterize dark energy and dark matter, and to test alternative models of gravity; these goals will be pursued by studying large-scale structure, cluster counts, weak gravitational lensing and Type Ia supernovae. However, DES also provides a rich data set which allows us to study many other aspects of astrophysics. In this paper, we focus on additional science with DES, emphasizing areas where the survey makes a difference with respect to other current surveys. The paper illustrates, using early data (from âScience Verificationâ, and from the first, second and third seasons of observations), what DES can tell us about the Solar system, the Milky Way, galaxy evolution, quasars and other topics. In addition, we show that if the cosmological model is assumed to be +cold dark matter, then important astrophysics can be deduced from the primary DES probes. Highlights from DES early data include the discovery of 34 trans-Neptunian objects, 17 dwarf satellites of the Milky Way, one published z > 6 quasar (and more confirmed) and two published superluminous supernovae (and more confirmed)
Dynamic and flexibility of Symbiodinium clades associated to corals in various environments : natural and controlled
Les coraux vivent en association symbiotique avec des algues dinoflagellĂ©es du genre Symbiodinium, distinguĂ©es en diffĂ©rents clades (A Ă I). Un mĂȘme hĂŽte peut abriter seul ou plusieurs de ces clades, a priori dĂ©pendant dâun contexte environnemental, suggĂ©rant quâils possĂšdent des propriĂ©tĂ©s physiologiques distinctes. Ainsi, les capacitĂ©s de flexibilitĂ© et dâacquisition de clades pourraient ĂȘtre une issue pour la survie de lâholobionte face Ă divers stress. Dans le cadre de cette thĂšse, ces capacitĂ©s ont Ă©tĂ© explorĂ©es chez plusieurs espĂšces coralliennes, dĂ©crites avec diffĂ©rentes flexibilitĂ©s et sensibilitĂ©s aux conditions environnementales. La diversitĂ© et la dynamique des communautĂ©s de Symbiodinium associĂ©es aux coraux ont Ă©tĂ© estimĂ©es Ă lâaide de la technique de PCR en temps rĂ©el et Ă©valuĂ©es dans diffĂ©rents contextes environnementaux: naturels, lors dâun suivi spatio-temporel de 18 mois Ă Moorea, ou contrĂŽlĂ©s, lors d'une incubation Ă diffĂ©rentes pCO2. Les coraux ont montrĂ© la possibilitĂ© dâhĂ©berger jusquâĂ 3 ou 4 clades distincts, reconsidĂ©rant la notion de spĂ©cialiste (i.e. symbionte unique). NĂ©anmoins, propre Ă lâhĂŽte corallien, il a Ă©tĂ© mis en Ă©vidence la rĂ©gulation de âsignatures symbiotiquesâ caractĂ©risĂ©es par des profils particuliers dâassociation de clades, stables et durables. Des modifications sporadiques de ces profils, par switching et shuffling ont put ĂȘtre observĂ©es, indĂ©pendamment dâun contexte environnemental donnĂ©, suggĂ©rant la dynamique comme un mĂ©canisme constitutif chez les coraux. NĂ©anmoins, en cas de dâapparition dâĂ©pizooties de Vibrio spp. et dâune maladie corallienne il est suggĂ©rĂ© que le clade D participe activement au âfitnessâ de leur hĂŽte.Corals live in symbiosis with dinoflagellate algae of the genus Symbiodinium, divided into 9 clades (A to I). The same host can harbour one or more of these clades depending on the environmental context. This lead to the suggestion that each clade has its unique physiological property. Therefore the capacity of flexibility and acquisition of clades may be an issue for the survival of the holobiont against various stresses. In this thesis, these capacities have been explored in several coral species, described with various flexibilities and sensitivities facing different environmental conditions. The diversity and dynamics of Symbiodinium communities associated to corals were estimated by using the real-time PCR technique, and evaluated in different environmental contexts : natural, in an 18-month spatio-temporal survey around Moorea, or controlled, upon incubation with different pCO2. Some corals showed the ability to host up to 3 or 4 distinct clades, leading to a reconsideration of the specialist-concept (i.e. host associated with one symbiont type). Nevertheless, depending on the coral host, âsymbiotic signatureâ regulations have been revealed. Latter are characterized by specific clade combination profils, which are stable and sustainable. In addition, sporadic changes by switching and shuffling, were observed in a given profil, regardless of a given environmental context, suggesting the dynamics as an constitutive mechanism in corals. However, records of coral disease together with Vibrio spp outbreaks, suggested an active participation of clade D for the âfitnessâ of the coral host
