Under pressure: costs of living, financial hardship and emergency relief in Victoria

'Under pressure: Costs of living, financial hardship and emergency relief in Victoria' presents the findings of a research project conducted between 2007 and 2008 on demand for emergency relief in Victoria. The research project was a partnership between the Victorian Council of Social Service (VCOSS), RMIT University and the emergency relief peak body ER Victoria. Emergency relief can be defined as the provision of critical support to individuals and families experiencing a financial emergency or crisis. Emergency relief assistance can include a food voucher or parcel, household goods, clothing and financial assistance for utilities or food. Emergency relief is currently provided by over 700 non-government organisations in Victoria

Asymptotics and local constancy of characters of p-adic groups

In this paper we study quantitative aspects of trace characters $\Theta_\pi$ of reductive $p$-adic groups when the representation $\pi$ varies. Our approach is based on the local constancy of characters and we survey some other related results. We formulate a conjecture on the behavior of $\Theta_\pi$ relative to the formal degree of $\pi$, which we are able to prove in the case where $\pi$ is a tame supercuspidal. The proof builds on J.-K.~Yu's construction and the structure of Moy-Prasad subgroups.Comment: Proceedings of Simons symposium on the trace formul

Classification and Lateralization of Temporal Lobe Epilepsies with and without Hippocampal Atrophy Based on Whole-Brain Automatic MRI Segmentation

Brain images contain information suitable for automatically sorting subjects into categories such as healthy controls and patients. We sought to identify morphometric criteria for distinguishing controls (n = 28) from patients with unilateral temporal lobe epilepsy (TLE), 60 with and 20 without hippocampal atrophy (TLE-HA and TLE-N, respectively), and for determining the presumed side of seizure onset. The framework employs multi-atlas segmentation to estimate the volumes of 83 brain structures. A kernel-based separability criterion was then used to identify structures whose volumes discriminate between the groups. Next, we applied support vector machines (SVM) to the selected set for classification on the basis of volumes. We also computed pairwise similarities between all subjects and used spectral analysis to convert these into per-subject features. SVM was again applied to these feature data. After training on a subgroup, all TLE-HA patients were correctly distinguished from controls, achieving an accuracy of 96 ± 2% in both classification schemes. For TLE-N patients, the accuracy was 86 ± 2% based on structural volumes and 91 ± 3% using spectral analysis. Structures discriminating between patients and controls were mainly localized ipsilaterally to the presumed seizure focus. For the TLE-HA group, they were mainly in the temporal lobe; for the TLE-N group they included orbitofrontal regions, as well as the ipsilateral substantia nigra. Correct lateralization of the presumed seizure onset zone was achieved using hippocampi and parahippocampal gyri in all TLE-HA patients using either classification scheme; in the TLE-N patients, lateralization was accurate based on structural volumes in 86 ± 4%, and in 94 ± 4% with the spectral analysis approach. Unilateral TLE has imaging features that can be identified automatically, even when they are invisible to human experts. Such morphometric image features may serve as classification and lateralization criteria. The technique also detects unsuspected distinguishing features like the substantia nigra, warranting further study

«La relation de limitation et d’exception dans le français d’aujourd’hui : excepté, sauf et hormis comme pivots d’une relation algébrique »

L’analyse des emplois prépositionnels et des emplois conjonctifs d’ “excepté”, de “sauf” et d’ “hormis” permet d’envisager les trois prépositions/conjonctions comme le pivot d’un binôme, comme la plaque tournante d’une structure bipolaire. Placées au milieu du binôme, ces prépositions sont forcées par leur sémantisme originaire dûment métaphorisé de jouer le rôle de marqueurs d’inconséquence systématique entre l’élément se trouvant à leur gauche et celui qui se trouve à leur droite. L’opposition qui surgit entre les deux éléments n’est donc pas une incompatibilité naturelle, intrinsèque, mais extrinsèque, induite. Dans la plupart des cas (emplois limitatifs), cette opposition prend la forme d’un rapport entre une « classe » et le « membre (soustrait) de la classe », ou bien entre un « tout » et une « partie » ; dans d’autres (emplois exceptifs), cette opposition se manifeste au contraire comme une attaque de front portée par un « tout » à un autre « tout ». De plus, l’inconséquence induite mise en place par la préposition/conjonction paraît, en principe, tout à fait insurmontable. Dans l’assertion « les écureuils vivent partout, sauf en Australie » (que l’on peut expliciter par « Les écureuils vivent partout, sauf [qu’ils ne vivent pas] en Australie »), la préposition semble en effet capable d’impliquer le prédicat principal avec signe inverti, et de bâtir sur une telle implication une sorte de sous énoncé qui, à la rigueur, est totalement inconséquent avec celui qui le précède (si « les écureuils ne vivent pas en Australie », le fait qu’ils « vivent partout » est faux). Néanmoins, l’analyse montre qu’alors que certaines de ces oppositions peuvent enfin être dépassées, d’autres ne le peuvent pas. C’est, respectivement, le cas des relations limitatives et des relations exceptives. La relation limitative, impliquant le rapport « tout » - « partie », permet de résoudre le conflit dans les termes d’une somme algébrique entre deux sous énoncés pourvus de différent poids informatif et de signe contraire. Les valeurs numériques des termes de la somme étant déséquilibrées, le résultat est toujours autre que zéro. La relation exceptive, au contraire, qui n’implique pas le rapport « tout » - « partie », n’est pas capable de résoudre le conflit entre deux sous énoncés pourvus du même poids informatif et en même temps de signe contraire : les valeurs numériques des termes de la somme étant symétriques et égales, le résultat sera toujours équivalent à zéro

Financial hardship and emergency relief in Victoria

The existence and provision of emergency relief remains one of the more contentious aspects of poverty relief in Australia. This is largely due to a fundamental difference of opinion within government and the welfare sector about how to best tackle the financial hardship being experienced by people in need. Some contend that emergency relief should be expanded and better funded by the Commonwealth, whereas others believe it should be discontinued altogether and replaced by more generous social welfare payments. This debate continues unresolved for a number of reasons, including a lack of reliable and comprehensive data on who uses emergency relief in Australia and why

‘Real men don't hit women’: Constructing masculinity in the prevention of violence against women

The primary prevention of violence against women has become a national and international priority for researchers and policy makers. While optimistic about the potential of the prevention agenda, this paper advances two related critiques of the construction of masculinities within violence against women primary prevention in high-income countries. The first is that it affords gender norms an unjustified priority over gender inequality as determinants of violence against women. The second critique is that the myopic focus of violence against women prevention efforts on gender norms results in a ‘one-dimensional’ view of masculinity. Nationally and internationally prominent violence against women prevention activities are grounded in a view of masculinity as a normative phenomenon dis-embedded from economic and political processes. As the paper argues, such a sanitised and one-dimensional account of masculinity is unable to explicable the practical steps necessary to achieve the aims of primary prevention. The paper argues that primary prevention efforts should be reorientated away from decontextualised and quasi-transcendental accounts of masculinity and towards non-violence as a suppressed possibility within the existing social order, and one that requires economic and political as well as cultural change if it is to be realised
