Introduction [to Doctrina perpetua: brokering change, promoting innovation and transforming marginalisation in university learning and teaching]

It is arguable that, in addition to brokering change and promoting innovation, contemporary universities have a responsibility to direct their teaching and learning activities at transforming marginalisation. This contention derives from the fundamental and enduring ambivalence attending discussions of the purpose and significance of universities. On the one hand, they can be seen as “ivory towers” and hence as the bastions of privilege and the repositories of “high culture”, overseeing the maintenance of what the elite determines is the best of a nation’s heritage. On the other hand, and by contrast, they can be viewed as the vehicles for progressive social change and as the sites for interrogating current issues in terms of whose voices are heard and whose are silenced in relation to those issues. Given this ambivalence, it is clearly incumbent on universities to find ways of confirming that they contribute to disrupting and subverting sociocultural inequities rather than replicating them. In keeping with the emphasis on diversity and heterogeneity evident throughout this book, the authors of the chapters in this section have been encouraged to deploy a number of conceptual and methodological resources in engaging with the theme of transforming marginalisation in preference to the section editor predetermining a single, fixed definition of “marginalisation” and its “transformation”. At the same time, each chapter identifies particular attributes of groups of learners that might potentially render them at greater risk than other groups of not attaining their educational goals and links those attributes with specific strategies that have been demonstrated through evidencebased practice to reduce that risk—at least for some learners in those groups. What emerges is a picture of considerable complexity, with some strategies proving effective for large numbers of students and conforming to the features of current best practice in university learning and teaching, yet also with some elements of marginalisation remaining remarkably resistant to amelioration and transformation. Understanding this complex and somewhat contradictory picture is crucial to taking up the challenges and opportunities that mark the intersection between doctrina perpetua and transforming marginalisation

Meeting the Expectations of Your Heritage Culture: Links between Attachment Style, Intragroup Marginalisation, and Psychological Adjustment

This article has been made available through the Brunel Open Access Publishing Fund.This article has been made available through the Brunel Open Access Publishing Fund.Do insecurely-attached individuals perceive greater rejection from their heritage culture? Few studies have examined the antecedents and outcomes of this perceived rejection – termed intragroup marginalisation – in spite of its implications for the adjustment of cultural migrants to the mainstream culture. The present study investigated whether anxious and avoidant attachment orientations among cultural migrants were associated with greater intragroup marginalisation and, in turn, with lower subjective well-being and flourishing, and higher acculturative stress. Anxious attachment was associated with heightened intragroup marginalisation from friends and, in turn, with increased acculturative stress; anxious attachment was also associated with increased intragroup marginalisation from family. Avoidant attachment was linked with increased intragroup marginalisation from family and, in turn, with decreased subjective well-being

Unemployment, Labour Marginalisation, and Deprivation (in English)

The increase in long-term unemployment and the prolongation of periods of unemployment signals the establishment of a marginalized labor force in the Czech Republic. This paper considers the emerging marginalized groups in the Czech labor market, and their social, mental, and material deprivation. A major determinant of the incidence of unemployment in a person's work career is human capital, indicated by completed education. Material deprivation is most severe in unemployed-affected households with dependents in which the breadwinner's income has been lost. It is also severe in single-parent households. Overall, it is particularly those in the non-qualified labor force who find themselves in a state of permanent material deprivation with respect to a high risk of unemployment. The effects of labor market marginalization on labor market performance are mostly negative due to a diminished employability, and, as a result, declining effective labor supply. A policy response should involve employment tax and benefit reform and the extension of activating measures, mainly of those supporting employability and human capital.wage curve, wage flexibility, unemployment, panel data

Nordic discourses on marginalisation through education

The purpose of this article is analysis of discursive marginalisation through education in Nordic welfare states. What knowledge do Nordic research discourses produce about marginalisation through education in Nordic welfare states? What are the Nordic contributions to research discourses on marginalisation through education? We apply a discourse theoretical approach and analyse 109 peer-reviewed publications on marginalisation by the Nordic Centre of Excellence “Justice through education in the Nordic countries” (NCoE JustEd) between 2013 and 2017. The publications are from Finland, Sweden, Norway and Iceland. Four critical Nordic research discourses reconceptualise marginalisation in relation to dominant educational discourses on marketisation, Eurocentrism, gender equity and ableism. These Nordic research discourses document discursive effects of the dominant, normalising discourses in terms of stigma, segregation and exclusion of poor, working-class students, non-white and immigrant students and descendants of immigrants, as well as sexual minorities and disabled students. Based on ethical, epistemological and methodological considerations, the critical Nordic research discourses produce knowledge about marginalisation as a relational, intersectional and interdiscursive phenomenon. The critical Nordic research discourses de- and reconstruct knowledge about marginalisation in Nordic welfare states.Peer reviewe

Extending BEAMS to incorporate correlated systematic uncertainties

New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic data. Avoiding biases in cosmological parameters due to the resulting inevitable contamination from non-Ia supernovae can be achieved with the BEAMS formalism, allowing for fully photometric supernova cosmology studies. Here we extend BEAMS to deal with the case in which the supernovae are correlated by systematic uncertainties. The analytical form of the full BEAMS posterior requires evaluating 2^N terms, where N is the number of supernova candidates. This `exponential catastrophe' is computationally unfeasible even for N of order 100. We circumvent the exponential catastrophe by marginalising numerically instead of analytically over the possible supernova types: we augment the cosmological parameters with nuisance parameters describing the covariance matrix and the types of all the supernovae, \tau_i, that we include in our MCMC analysis. We show that this method deals well even with large, unknown systematic uncertainties without a major increase in computational time, whereas ignoring the correlations can lead to significant biases and incorrect credible contours. We then compare the numerical marginalisation technique with a perturbative expansion of the posterior based on the insight that future surveys will have exquisite light curves and hence the probability that a given candidate is a Type Ia will be close to unity or zero, for most objects. Although this perturbative approach changes computation of the posterior from a 2^N problem into an N^2 or N^3 one, we show that it leads to biases in general through a small number of misclassifications, implying that numerical marginalisation is superior.Comment: Resubmitted under married name Lochner (formally Knights).

Combining cosmological datasets: hyperparameters and Bayesian evidence

A method is presented for performing joint analyses of cosmological datasets, in which the weight assigned to each dataset is determined directly by it own statistical properties. The weights are considered in a Bayesian context as a set of hyperparameters, which are then marginalised over in order to recover the posterior distribution as a function only of the cosmological parameters of interest. In the case of a Gaussian likelihood function, this marginalisation may be performed analytically. Calculation of the Bayesian evidence for the data, with and without the introduction of hyperparameters, enables a direct determination of whether the data warrant the introduction of weights into the analysis; this generalises the standard likelihood ratio approach to model comparison. The method is illustrated by application to the classic toy problem of fitting a straight line to a set of data. A cosmological illustration of the technique is also presented, in which the latest measurements of the cosmic microwave background power spectrum are used to infer constraints on cosmological parameters.Comment: 12 pages, 6 figures, submitted to MNRA

Marginalising instrument systematics in HST WFC3 transit lightcurves

Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) infrared observations at 1.1-1.7$\mu$m probe primarily the H$_2$O absorption band at 1.4$\mu$m, and has provided low resolution transmission spectra for a wide range of exoplanets. We present the application of marginalisation based on Gibson (2014) to analyse exoplanet transit lightcurves obtained from HST WFC3, to better determine important transit parameters such as R$_p$/R$_*$, important for accurate detections of H$_2$O. We approximate the evidence, often referred to as the marginal likelihood, for a grid of systematic models using the Akaike Information Criterion (AIC). We then calculate the evidence-based weight assigned to each systematic model and use the information from all tested models to calculate the final marginalised transit parameters for both the band-integrated, and spectroscopic lightcurves to construct the transmission spectrum. We find that a majority of the highest weight models contain a correction for a linear trend in time, as well as corrections related to HST orbital phase. We additionally test the dependence on the shift in spectral wavelength position over the course of the observations and find that spectroscopic wavelength shifts $\delta_\lambda(\lambda)$, best describe the associated systematic in the spectroscopic lightcurves for most targets, while fast scan rate observations of bright targets require an additional level of processing to produce a robust transmission spectrum. The use of marginalisation allows for transparent interpretation and understanding of the instrument and the impact of each systematic evaluated statistically for each dataset, expanding the ability to make true and comprehensive comparisons between exoplanet atmospheres.Comment: 19 pages, 13 figures, 8 tables, Accepted to Ap

A comparative examination of policy and models of disability in Korea and the UK

Over the last three decades, the understanding of disability has changed substantially, changes in theoretical debates and policy on disability now encourage society to understand and treat disabled people as ordinary citizens. However, arguably the dominance of Western theory on disability has resulted in the marginalisation of disabled people’s experiences in non Western cultures. This paper compares disability in relation to the culture of South Korea and the UK, by attempting to articulate some of the implicit values of disability and development of the relevant disability polic

Museums as disseminators of niche knowledge: Universality in accessibility for all

Accessibility has faced several challenges within audiovisual translation Studies and gained great opportunities for its establishment as a methodologically and theoretically well-founded discipline. Initially conceived as a set of services and practices that provides access to audiovisual media content for persons with sensory impairment, today accessibility can be viewed as a concept involving more and more universality thanks to its contribution to the dissemination of audiovisual products on the topic of marginalisation. Against this theoretical backdrop, accessibility is scrutinised from the perspective of aesthetics of migration and minorities within the field of the visual arts in museum settings. These aesthetic narrative forms act as modalities that encourage the diffusion of ‘niche’ knowledge, where processes of translation and interpretation provide access to all knowledge as counter discourse. Within this framework, the ways in which language is used can be considered the beginning of a type of local grammar in English as lingua franca for interlingual translation and subtitling, both of which ensure access to knowledge for all citizens as a human rights principle and regardless of cultural and social differences. Accessibility is thus gaining momentum as an agent for the democratisation and transparency of information against media discourse distortions and oversimplifications
