A large point-source outbreak of Salmonella Typhimurium linked to chicken, pork and salad rolls from a Vietnamese bakery in Sydney
Sophie Norton,Essi Huhtinen,Stephen Conaty,Kirsty Hope
Western Pacific Surveillance and Response , 2012,
Abstract: Introduction: In January 2011, Sydney South West Public Health Unit was notified of a large number of people presenting with gastroenteritis over two days at a local hospital emergency department (ED).Methods: Case-finding was conducted through hospital EDs and general practitioners, which resulted in the notification of 154 possible cases, from which 83 outbreak cases were identified. Fifty-eight cases were interviewed about demographics, symptom profile and food histories. Stool samples were collected and submitted for analysis. An inspection was conducted at a Vietnamese bakery and food samples were collected and submitted for analysis. Further case ascertainment occurred to ensure control measures were successful.Results: Of the 58 interviewed cases, the symptom profile included diarrhoea (100%), fever (79.3%) and vomiting (89.7%). Salmonella Typhimurium multiple-locus-variable number tandem repeats analysis (MLVA) type 3-10-8-9-523 was identified in 95.9% (47/49) of stool samples. Cases reported consuming chicken, pork or salad rolls from a single Vietnamese bakery. Environmental swabs detected widespread contamination with Salmonella at the premises.Discussion: This was a large point-source outbreak associated with the consumption of Vietnamese-style pork, chicken and salad rolls. These foods have been responsible for significant outbreaks in the past. The typical ingredients of raw egg butter or mayonnaise and pate are often implicated, as are the food-handling practices in food outlets. This indicates the need for education in better food-handling practices, including the benefits of using safer products. Ongoing surveillance will monitor the success of new food regulations introduced in New South Wales during 2011 for improving food-handling practices and reducing foodborne illness.
An Exploratory Study of Altruism in Greek Children: Relations with Empathy, Resilience and Classroom Climate  [PDF]
Sophie Leontopoulou
Psychology (PSYCH) , 2010, DOI: 10.4236/psych.2010.15047
Abstract: The aims of this exploratory study were two-fold: a. to identify any relations between children’s altruism and a set of demographic and other personal and social characteristics of Greek children, such as empathy, resilience and classroom climate; and b. to examine the psychometric properties of a newly-developed measure of altruistic behaviour in children, namely the Altruistic Behaviour Questionnaire (ABQ). 232 male and female students of the 5th and 6th class of Primary School in Northern Greece participated in this study. The ABQ was found to have adequate internal consistency and concurrent and construct validity. Using a hierarchical regression analysis, altruism in children was found to be reliably predicted by participants’ gender and academic performance, by empathy and also by resilience; nevertheless, the more socially determined variable of classroom climate only marginally predicted altruism. The importance of including training in the development and manifestation of altruism in emotional education programmes and resilience interventions at school is highlighted.
Examining the Relationship between Hope and Attachment: A Meta-Analysis  [PDF]
John Blake, Christine Lynn Norton
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.56065
Abstract:

The authors report quantitative findings from a meta-analysis of studies investigating the relationship between attachment style, grounded in theory developed by Bowlby and Ainsworth; and Snyder’s theoretical model of hope (Ainsworth & Bowlby, 1991; Snyder, 1994). Statistically significant results provide support for further investigation of clinical value of the attachment/hope dynamic as an effective heuristic for conceptualizing human development, behavior and the therapeutic process.

Chocolate para el imperio: la interiorización europea de estética mesoamericana
Norton,Marcy;
Revista de Estudios Sociales , 2008,
Abstract: this article offers a new interpretation of how and why europeans developed a taste for chocolate. while previous studies have suggested that europeans transformed chocolate materially and ideologically in order to make it fit their existing set of tastes and prejudices, it is demonstrated that europeans learned to like chocolate on indian terms as a result of their status as cultural minorities in colonial mesoamerica. in addition this article uses the historical case study of chocolate's transcultural migration to revise current models of taste used in historical and anthropological literature. it rejects biologicalessentialism and culturalfunctionalism and instead shows that taste is an independent historical variable affected by social circumstances.

Tromino Tiling Deficient Cubes of Any Side Length
Norton Starr
Mathematics , 2008,
Abstract: We show that three dimensional cubes of any size can be tiled with trominoes and, when necessary, one or two singletons in any positions. Cubes of side length a multiple of three can always be tiled with trominoes (known), cubes of side length congruent to 1 mod 3 can always be tiled with an arbitrary single cube and trominoes, and cubes of side length congruent to 2 mod 3 can always be tiled with two single cubes in arbitrary locations and trominoes.
Symplectic Reflection Algebras in Positive Characteristic as Ore Extensions
Emily Norton
Mathematics , 2013,
Abstract: We investigate PBW deformations H of k[x,y]#G where G is the cyclic group of order p and k also has characteristic p; in these deformations, [x,y] takes a value in kG. These algebras are versions of symplectic reflection algebras that only exist in positive characteristic. They also happen to possess a presentation as an Ore extension over a commutative subring R, and via the derivation defining the extension, have interesting connections to certain polynomials appearing in combinatorics and related to alternating permutations (the Andr\'e polynomials). We find the center of these algebras, their Verma modules, their simple modules, and the Ext groups between simples. The Verma modules coincide with the fibers of Mod H -->> Spec R, and Mod H turns out to be the disjoint union, in the sense of Smith and Zhang, of the Verma modules. As in non-defining characteristic, there are some distinctions between the t=0 and t=1 cases. We also obtain results when G is replaced with an elementary abelian p-group E: in particular, we find the center and the simple modules when [x,y] is in k[E].
Irreducible representations of rational Cherednik algebras for exceptional Coxeter groups, Part I
Emily Norton
Mathematics , 2014,
Abstract: This paper and its sequel describe the irreducible representations of the rational Cherednik algebra $H_c(W)$ for a finite Coxeter group $W$ of type $H_4$, $F_4$ with equal parameters, $E_6$, $E_7$, and $E_8$, when $c$ is not a half-integer. Herein appear the decomposition matrices of Category $\mathcal{O}_c(W)$ for $W=H_4$, $E_6$, and $E_7$, as well as a classification of finite-dimensional representations of $H_c(W)$ for these groups and for $H_c(F_4)$ with equal parameters.
An algorithm for the orthogonal decomposition of financial return data
Vic Norton
Quantitative Finance , 2012,
Abstract: We present an algorithm for the decomposition of periodic financial return data into orthogonal factors of expected return and "systemic", "productive", and "nonproductive" risk. Generally, when the number of funds does not exceed the number of periods, the expected return of a portfolio is an affine function of its productive risk.
Notional portfolios and normalized linear returns
Vic Norton
Quantitative Finance , 2011,
Abstract: The vector of periodic, compound returns of a typical investment portfolio is almost never a convex combination of the return vectors of the securities in the portfolio. As a result the ex post version of Harry Markowitz's "standard mean-variance portfolio selection model" does not apply to compound return data. We propose using notional portfolios and normalized linear returns to remedy this problem.
