Separation of different forms of proteose peptone 3 by hydrophobic interaction chromatography with a dual salt system

A panel of four hydrophobic adsorbents (butyl-, octyl-, phenyl- and epoxy-Sepharose) was used to examine the selectivity and fractionation of several proteose peptone 3 (PP3) forms from a freeze-dried extract of whey bovine milk. In particular, the effects of altering the ligand type and salt were investigated. The chromatographic studies suggest that PP3 strongly interacts among the three commercial hydrophobic resins leading to a drop off in selectivity, while a complete binding was achieved at low salt concentrations (below 0.5 M) and total elution only with phosphate buffer and/or water stepwise conditions. Only in epoxy–Sepharose was an appreciably selectivity of the several fractions of PP3 present in the initial feedstock attained. Despite the high salt concentration for a complete binding of PP3 (above 1.5 M ammonium sulfate) onto this support, the dual salt system (ammonium sulfate 1 M and sodium citrate 0.8 M) led to a high separation degree of high and low molecular weight forms of PP3

Révolution française et littérature anglaise

Il est largement admis que la Révolution française a eu un impact énorme sur la littérature anglaise et que pratiquement tous les poètes, romanciers et auteurs dramatiques de cette époque ont écrit des textes influencés par les principes et par les remarquables événements français. Cet article se penche sur les travaux récents consacrés aux écrivains de fiction que la Révolution française a enthousiasmés, à ceux qu’elle a effrayés ou horrifiés, et à ceux qui, après l’avoir saluée, l’ont ensuite critiquée.The French Revolution and English Literature. It is widely recognised that the French Revolution had an enormous impact on English literature and that almost all contemporary poets, novelists and playwrights wrote works directly influenced by French principles and by the remarkable events in France. This essay looks in particular at recent studies of those writers of imaginative literature who were excited and attracted by the French Revolution, those who were frightened and  appalled by developments in France, and those who initially welcomed the French Revolution but later became its critics

The 'new majority' and the academization of journalism

The academization of journalism is reliant on the development of the field founded in scholarship demonstrated through the publication of research in peer-reviewed specialist journals. Given the profile of journalism faculty, this means inducting practitioners into a culture of critical research. In Australia at least, this cohort of neophytes is predominantly comprised of middle-aged women who were surveyed about their personal attitudes to research. They were mostly open to the idea of becoming researchers but were inclined to proceed cautiously without necessarily severing their ties with practice. There was evidence to suggest that a generally positive orientation to research was not capitalized on and that they remained uncertain about the role of research. On the other hand, they appeared not to have adopted the orthodoxy of implacable opposition to scholarly inquiry. The change in gender composition in the academy may provide, contrary to historical, but more in line with contemporary, evidence, a renewed impetus to the project of academizing the field

The uses and abuses of power: teaching school leadership through children's literature

There are relatively few studies of how representations of teachers, schools and educational administrators in popular films and television might be, and are, used in leadership preparation. This paper seeks to add to this small body of work; it reports on an exploratory study of the representation of headteachers in contemporary children's fiction. Thirty-one texts are analysed to ascertain key themes and the major characterisations. The paper draws on children's literature scholars to argue that both the historical school story and its contemporary counterpart focus heavily on the power of the head to control the micro-world of the school. Because these fictional accounts deal with issues of power and justice more openly than many mainstream educational administration texts, this makes them particularly useful in the preparation of potential school leaders
