No full textBattle of the Blockbusters: Joss Whedon as Public Pedagogue
No full textThis article discusses the concept of public pedagogy and the reasons for considering it relevant to the work of the writer/ director/ producer Joss Whedon, creator of numberous TV programmes, such as Buffy the Vampire Slayer, Angel and Firefly, and Films Serenity, Marvel's The Avengers and The Age of Ultron. It analyzes Marvel’s The Avengers (Whedon, 2012) and Christopher Nolan’s (2012b) The Dark Knight Rises as competing public pedagogies.It suggests that popular films can be seen as important educational projects; filmmakers have tremendous resources at their disposal and their creations have a global reach that cannot be matched by individual teachers or national education systems. Whedon can be seen as a radical educator; he enables his audiences to experience ways of looking at the world that challenge aspects of neo-liberal hegemony, and also encourages them to become critical thinkers who have to reflect on their own feelings and perspectives and resist simplistic perspectives on morality and the difficult political choices facing global society

No full textHow to be a woman. Models of masochism and sacrifice in young adult fiction
No full textBuffy, Bella, Veronica, Katniss, Clary, Tris and Saba : For two decades post-feminist heroines have faced life-threatening trials as part of their progress to womanhood. In this chapter I consider how young adult popular fictions operate as forms of pedagogy for young women by offering them particular models of maturity and womanhood. I explore the recurrence and reformulation of a persistent pattern of behaviour in which heroines engage in risky and/or masochistic behaviours for which they are emotionally rewarded.. These recurrences function as a form of vicarious experiential learning in which readers and viewers learn that emotional gratification and adult status are conferred through self-harm and self-sacrifice. Popular culture is not a monolithic form and young adult fictions are no exception. An analysis of fictional examples of this behaviour pattern challenges the idea that heroines today are empowered agents as a result of the legacy of feminism. At the same time, the analysis belies any notion that fictions are universally hegemonic and oppressive – fictions can and do disrupt and interrogate this pattern of emotional masochism. Scholars of public pedagogy have explored the complexities, contradictions and subtleties of the pedagogical process. Sandlin O’Malley and Burdick (2011) in their review of public pedagogy literature acknowledge that some scholarship has demonstrated how “the teaching and learning inherent within daily life can be both oppressive and resistant” (p. 144). Jubas and Knutson (2012) also see public pedagogy as an arena where contradictions and tensions are in play. They argue that we can see “New examples of dialectic or tensions … between the authority of the producer and the consumer; between traditional structures which ground identities and help people make sense of cultural texts, and personal agency which frees people to choose and invent identities and meanings” (p. 86). This analysis aims to contribute to understandings of the complexities of public pedagogy by showing how fictions aimed primarily at young women both resist and accommodate patriarchy
Characterization of Neutral Trapped Antihydrogen in the ALPHA Experiment
No full textOne of the pivotal principles of physics is the C (charge) P (parity) T (time reversal) (CPT) theorem. One method for testing the CPT symmetry is to investigate the properties of antihydrogen. The Antihydrogen Laser PHysics Apparatus (ALPHA) experiment aims at creating, confining and applying spectroscopic techniques to probe the atomic structure of antihydrogen anti-atom with the same accuracy as that of the hydrogen atom.
There are several non-trivial experimental challenges that must be overcome in antihydrogen studies. One major challenge is the detection of antihydrogen anti-atoms. This is done by identifying the antihydrogen annihilation. This thesis presents both a new method for identifying signal pulses from the background electric pulses of the silicon strips (Alternative Pedestal Analysis (APA), see Appendix A) as well as a completely new and enhanced vertex reconstruction method (Alternative Reconstruction Method (ARM), see Appendix C). The ARM is based on implementing a set of filtration mechanisms to identify the track candidates. Moreover, the reconstruction of the tracks is accomplished by adapting a numerical approach. Combining the APA and the ARM schemes has led to an increase in the vertex reconstruction efficiency by 1.5%.
The alternative approaches for pedestal analysis and vertex reconstruction utilize a considerably more versatile algorithm. This feature allows greater control over variables and selection parameters employed for the reconstruction of vertices. The conclusive verifications of the performances of the new approaches are based on their visualization capabilities, the key aspect in devising the APA and the ARM, see Appendices B and D. The scripts in Appendices A-D haven been written solely by the author and are completely independent of pedestal and even vertex reconstruction algorithms currently implemented in the ALPHA experiment. The full commented versions of the scripts in Appendices A-D are available via the accompanying website
A simple and fast method for the isolation of basolateral plasma membranes from rat small-intestinal epithelial cells
No full textA method was developed for the analytical and preparative isolation of basolateral plasma membranes from rat small intestine. They were separated on a self-orientating Percoll (modified colloidal silica) gradient starting with a heavy microsomal-membrane fraction and involving centrifugation at 48,000 g for 1 h. (Na++ K+)-stimulated ATPase activity, used as a marker enzyme for the basolateral plasma membrane, is enriched 20-fold compared with that found in the homogenate of isolated intestinal epithelial cells

Cataclysmic variables from a ROSAT/2MASS selection. I, Four new intermediate polars
No full textWe report the first results from a new search for cataclysmic variables (CVs) using a combined X-ray (ROSAT)/infrared (2MASS) target selection that discriminates against background active galactic nuclei. Identification spectra were obtained at the Isaac Newton Telescope for a total of 174 targets, leading to the discovery of 12 new CVs. Initially devised to find short-period low-mass-transfer CVs, this selection scheme has been very successful in identifying new intermediate polars. Photometric and spectroscopic follow-up observations identify four of the new CVs as intermediate polars: 1RXS J063631.9+353537 P(orb)similar or equal to 201 min, P-spin= 1008.3408 s or 930.5829 s), 1RXS J070407.9+262501 (P(orb)similar or equal to 250 min, P-spin= 480.708 s) 1RXS J173021.5-055933 (P-orb= 925.27 min, P-spin= 128.0 s), and 1RXS J180340.0+401214 (P-orb= 160.21 min, P-spin= 1520.51 s). RX J1730, also a moderately bright hard X-ray source in the INTEGRAL/IBIS Galactic plane survey, resembles the enigmatic AE Aqr. It is likely that its white dwarf is not rotating at the spin equilibrium period, and the system may represent a short-lived phase in CV evolution

Bibliometric dataset (1990–2019) concerning 35 city labels dealing with sustainable urbanism
No full textThis data article presents a tripartite dataset that formed the empirical basis for a comprehensive bibliometric analysis of the use of city labels denoting sustainable urbanism in the scientific literature (Schraven, 2021). The tripartite dataset was generated using the abstract and citation database Scopus (Elsevier). Dataset A lists 148 city labels denoting different approaches to urban planning and development. It was used to select 35 city labels that specifically address sustainable urbanism (‘sustainable city’, ‘smart city’, ‘compact city’ etc.). Dataset B references 11,337 journal and review articles spanning the period 1990–2019. All retrieved articles contain at least one of the 35 city labels in the title, abstract, and author keywords. This database was used to calculate the frequency of the selected city labels across time, and to analyze the co-occurrences of city labels. It was further used to calculate the future trajectory of scientific outputs using the Logistic Growth Model (LGM). Dataset C entails 22,820 author keywords extracted from across the 11,337 articles. This was used to analyze the co-occurrences of keywords with city labels. The data article describes the methods of data collection and curation, the analysis performed, and the potential for reusing the data for further research. The comprehensiveness of the bibliometric corpus – spanning three decades and 35 city labels – lends itself to further investigation of how sustainable urban development has evolved as a topic in the scientific literature since the 1990s. Furthermore, the robust methodology developed could be adapted to other scientific repositories and, indeed, other research problems and questions.Integral Design & ManagementOrganisation & Governanc
