The Politics of Regulation: Adolescent Mothers and the Social Context of Resiliency
No full textThe experiences of adolescent mothers have too often been reduced to patterns of correlation linking teenage parenthood with low educational attainment, persistent poverty and continued welfare dependency. These analyses have reinforced representation of an "undeserving poor" and the tendency to "blame the victim" for her structural condition and her dependence on the state. Researchers in adolescent development have attempted to move beyond pathologizing frameworks by considering the "resiliency" of young mothers; yet their contributions have been limited by the tendency to reduce experience to the level of psychological coping mechanisms. In this article, I build upon more recent work as I explore the multifaceted ways in which resiliency can be interpreted. Drawing form the experiences of adolescent mothers within the care of the child welfare system, I illustrate empirically that resiliency is not an intrinsic, psychological characteristic but rather, shifts in relation to particular social contexts and policies.This article was published in Voices.

Nanoscale silver: Thin-film structure and antimicrobial functionality
No full textSince antiquity, silver has been used as a material to reduce spoilage. Over the past decades, there has been an increasing scientific and commercial interest in developing silver surfaces due to the increasing number of drug resistant microorganisms. In this study, the effect of nanostructuring silver films as an antimicrobial against the bacteria Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was examined. Films consisting of 3 nm chromium adhesion layers and nominal 20 nm silver surfaces (assuming flat deposition) were deposited by thermal evaporation and nanostructuring was controlled by varying the incident angle of the silver onto the substrate. Four substrate angles were used including 0 °, 18 °, 40 ° and 70 ° to the horizontal. Examination by atomic force microscope, Rutherford backscattering and ellipsometry showed that as the incident angle of deposition increased, so did the nanostructuring and surface roughness. This was coupled with a decrease in film thickness. Incubation of the nanostructured thin-films in bacterial broths with E. coli and S. aureus showed that as the surface roughness increased the antimicrobial activity was enhanced – both in solution and for bacteria adhered to the thin-films. Inductively coupled plasma mass spectrometry was used to measure silver leaching from the thin-films and showed a negligible loss for all films, with corresponding low-levels of antimicrobial activity. Further indicating the enhancing effect of nanostructuring as an antimicrobial. All thin-films showed biological fouling after prolonged exposure to the bacterial solutions, which reduced antimicrobial activity. Cleaning the films with IPA showed that the films could be regenerated but with some loss of antimicrobial activity. The mechanism of thin-film antimicrobial activity is at this time unknown but it is speculated that nanostructuring is capable of penetrating the cell envelopes of bacteria, which enhances the antimicrobial activity of silver

Monodromy groups : the minimum genus problem
No full textEvery finite group is isomorphic to the monodromy group of some Riemann surface. In this thesis the minimum genus of those Riemann surfaces with monodromy group isomorphic to the finite group G is investigated for various G. A method is found for using groups of minimum genus 0 to produce wreath products of the same minimum genus. The minimum genus of many Frobenius groups with cyclic Frobenius subgroups, including all those in which the Frobenius kernel is also cyclic, is evaluated. The minimum genus of all dicyclic groups is found. For various p-groups the minimum genus is again evaluated. Many simple groups are investigated. In particular the minimum genus is evaluated for all Suzuki groups, for all PSL2(q) Hurwitz groups and for all PSL2(q) groups in which q is a power of 2 or 3, although in this last case the calculation of the minimum genus for a particular q depends on at least a partial factorization of a certain integer. PSL2(41) has the unusual property of being a Hurwitz group in which the minimum genus is not attained by a (2, 3, 7) generating triple. It is found to be the only such PSL2(q) Hurwitz group. An investigation is carried out with the An Hurwitz groups and all but finitely many are proved not to have the property.</p
Tumour targeting with indium and silver labelled macrocycles
No full textMonoclonal antibodies which recognise tumour associated antigens provide a means of targeting radionuclides selectively to tumour cells. Work has been directed towards the synthesis of functionalised macrocyclic ligands to bind indium(III) [(^111)In:- γ-emitter] and gallium(III) [(^67)Ga:- γ-emitter] for use in radioimmunoscintigraphy and silver(I) [(^111)Ag:- β-emitter] for use in radioimmunotherapy. Macrocyclic ligands have been selected to bind the respective radionuclides rapidly, under mild conditions, to form complexes which are kinetically inert in vivo. Four tribasic hexadentate macrocyclic ligands (9, 10, 11 and 12-membered rings) have been synthesised to bind indium and gallium. Comparison of the rate of (^111)In uptake under mild conditions at low concentration (10-100 µM) revealed that the nine-membered triaza-triacid was the most effective. The X-ray crystal structures of the indium and gallium complexes of the [9]-N(_3)-triacid have been determined. A C-functionalised derivative of the [9]-N(_3)-triacid has been synthesised by two routes, both starting from (2S)-Lysine. The syntheses of two N-functionalised derivatives of the [9]-N(_3)-triacid are also described. Antibody linkage has been effected (in collaborative work with Celltech Ltd.) by reacting the functionalised macrocycle with a heterobifunctional linker molecule (maleimide ester) followed by incubation with the antibody (previously treated with 2-iminothiolane).Three new nitrogen and sulphur donor macrocyclic ligands have been synthesised to bind silver(I) and the 1:1 silver complexes have been isolated as crystalline solids and characterised by FAB mass spectrometry and (^1)H nmr. Silver(I) complexes of two of the ligands have been characterised by X-ray crystallographic analysis. The stability constants (log K(_s), MeOH) for the silver(1) complexes of the[18]-membered N(_4)S(_2) and N(_4)S(_2)Me(_4) macrocyclic ligands (14.1 and 14.6respectively) are the highest recorded for monocyclic ligands
