‘I am content with Canada’: Canadian girls at the turn of the twentieth century

This essay focuses on British girls' periodicals and novels published around the turn of the twentieth century that generate an imagined picture of Canadian girlhood; I also begin to contrast these representations with those produced and published in Canada.

Constructing girlhood through the periodical press, 1850-1915

Focusing on six popular British girls' periodicals, Kristine Moruzi explores the debate about the shifting nature of Victorian girlhood between 1850 and 1915. During an era of significant political, social, and economic change, girls' periodicals demonstrate the difficulties of fashioning a coherent, consistent model of girlhood. The mixed-genre format of these magazines, Moruzi suggests, allowed inconsistencies and tensions between competing feminine ideals to exist within the same publication. Adopting a case study approach, Moruzi shows that the Monthly Packet, the Girl of the Period Miscellany, the Girl's Own Paper, Atalanta, the Young Woman, and the Girl's Realm each attempted to define and refine a unique type of girl, particularly the religious girl, the 'Girl of the Period,' the healthy girl, the educated girl, the marrying girl, and the modern girl. These periodicals reflected the challenges of embracing the changing conditions of girls' lives while also attempting to maintain traditional feminine ideals of purity and morality. By analyzing the competing discourses within girls' periodicals, Moruzi's book demonstrates how they were able to frame feminine behaviour in ways that both reinforced and redefined the changing role of girls in nineteenth-century society while also allowing girl readers the opportunity to respond to these definitions.

The ‘Australian Girl’ and the domestic ideal in colonial women’s fiction

The vast majority of novels and periodicals read by colonial Australian girls were written and published in Britain. ‘Daughters of the Southern Cross’ were more likely to have access to the Girl’s Own Paper by subscription or to imported fictions that had proven popular with British girl readers than any locally produced depictions of girlhood. From the 1880s, however, Australian authors produced several milestone fictions of girlhood for both adult and juvenile audiences. Rosa Praed's An Australian Heroine (1880) and Catherine Martin’s An Australian Girl (1890)  gave voice to the lived experience of Australia for young women, and their publication in Britain contributed to an emergent reciprocal transpacific flow of literary culture.

Two canonical Australian novels that focus on the maturation of girl protagonists who live on bush homesteads were also published in this period. Ethel Turner’s Seven Little Australians (1894) and Miles Franklin’s My Brilliant Career (1901) feature intelligent girls who are not able to be effectively socialised to embrace domesticity. Turner’s Judy Woolcot is distinct among her six siblings as a plucky girl who instigates trouble, while Franklin’s aspiring writer Sybylla Melvyn is informed that ‘girls are the helplessest, uselessest, troublesomest little creatures in the world.’

The 1890s saw an agricultural depression in Australia that only fuelled the urban perpet-uation of the idealised and nationalistic bushman myth in literary and popular culture. The ubiquity of the myth problematised any attempt to situate women heroically within the nation outside of the home. British fictional imaginings of Australian girls lauded their lack of conformity and physical abilities and often showed them bravely defending the family property with firearms. In contrast, Australian domestic fiction, this chapter argues, is unable to accommodate bracing female heroism, postulating ambiguous outcomes at best for heroines who deviate from the feminine ideal.

Judy’s grandmother describes her ‘restless fire’ as something that ‘would either make a noble, daring, brilliant woman of her’, or ‘would flame up higher and higher and consume her’. Turner does not allow Judy’s unconventionality to prosper. Instead, she is killed by a falling gum tree while saving the life of her brother, leaving the future fulfilment of the domestic ideal to her sister, Meg, whose subsequent story occupies Little Mother Meg (1902). Franklin’s Sybylla expresses her inability to be content with the simple pleasures of keeping a home, and this informs her decision to reject a marriage proposal from a wealthy suitor. The novel’s indeterminate conclusion does not allow fulfilment of Sybylla’s writing aspirations, situating her outside the feminine ideal yet not affirming the merits of her desire to reject married life.

While Sharyn Pearce suggests that Judy’s tragic end follows a narrative pattern that sup-ports the glorification of male heroes and renders ‘over-reaching women’ as ‘noble failures’, the novel might also productively be read within the context of other fictions featuring girl protagonists of the period, such as Praed and Martin's novels. This chapter makes the case that Turner and Franklin’s thwarted heroines critique the containment of Australian girls to the banalities of the home by exposing the negative and uncertain outcomes for those who desire the freedoms and aspirations permitted to boys and men. Unlike British fictions that champion adventurous girls, these Australian fictions critique the continuation of gendered restrictions in the colonies by proposing that girls who desire excitement and independence ‘should have been…boy[s]’ (as Sybylla’s mother remarks).

Developing and using an S3R model to analyze reasoning in web-based cross-national exchanges on sustainability

Within the increasing body of research that examines students' reasoning on socioscientific issues, we consider in particular student reasoning concerning acute, open-ended questions that bring out the complexities and uncertainties embedded in ill-structured problems. In this paper, we propose a socioscientific sustainability reasoning (S3R) model to analyze students' reasoning exchanges on environmental socially acute questions (ESAQs). The paper describes the development of an epistemological analysis of how sustainability perspectives can be integrated into socioscientific reasoning, which emphasizes the need for S3R to be both grounded in context and collective. We argue the complexity of ESAQs requires a consideration of multiple dimensions that form the basis of our S3R analysis model: problematization, interactions, knowledge, uncertainties, values, and governance. For each dimension, in the model we have identified indicators of four levels of complexity. We investigated the usefulness of the model in identifying improvements in reasoning that flow from cross-national web-based exchanges between groups of French and Australian students, concerning a local and a global ESAQ. The S3R model successfully captured the nature of reasoning about socioscientific sustainability issues, with the collective negotiation of multiple forms of knowledge as a key characteristic in improving reasoning levels. The paper provides examples of collaborative argumentation in collective texts (wikis) to illustrate the various levels of reasoning in each dimension, and diagrammatic representation of the evolution of collective reflections. We observe that a staged process of construction and confrontation, involving groups representing to some extent different cultural and contextual stances, is powerful in eliciting reasoned argument of enhanced quality. © 2014 Wiley Periodicals, Inc.

Are urinary porphyrins a valid diagnostic biomarker of autism spectrum disorder?

A fundamental challenge to the timely diagnosis of Autism Spectrum Disorder (ASD) is the reliance on the observation of a set of aberrant behavior. Consequently, the diagnostic process requires that the child reach an age where the behaviors would typically be exhibited. The identification of a reliable biological marker (biomarker) could be of considerable benefit to the diagnostic process. As a diagnostic biomarker, porphyrins present an attractive prospect as previous studies have reported consistent findings of children with ASD showing significant elevations in porphyrin levels in contrast to controls. Furthermore, there is some evidence that ASD severity may be associated with porphyrins, which would be a valuable characteristic of any ASD biomarker. Importantly, for practical use, porphyrins can be tested non-invasively via a sample of urine. The present study sought to investigate whether porphyrin profiles can reliably be used to (a) differentiate ASD cases from healthy controls; and (b) predict ASD severity. The study compared the porphyrin levels of three groups of children aged 2-6 years: Group 1-children diagnosed with ASD (n = 70); Group 2-healthy, normally developing siblings of children diagnosed with ASD (n = 36); and Group 3-healthy, normally developing children with no known blood relative diagnosed with ASD (n = 54). The results of logistic regression analyses failed to find support for the hypotheses that porphyrin levels could be used as a valid tool to detect ASD cases or predict severity.

Altering the redox state of skeletal muscle by glutathione depletion increases the exercise-activation of PGC-1α

We investigated the relationship between markers of mitochondrial biogenesis, cell signaling, and antioxidant enzymes by depleting skeletal muscle glutathione with diethyl maleate (DEM) which resulted in a demonstrable increase in oxidative stress during exercise. Animals were divided into six groups: (1) sedentary control rats; (2) sedentary rats + DEM; (3) exercise control rats euthanized immediately after exercise; (4) exercise rats + DEM; (5) exercise control rats euthanized 4 h after exercise; and (6) exercise rats + DEM euthanized 4 h after exercise. Exercising animals ran on the treadmill at a 10% gradient at 20 m/min for the first 30 min. The speed was then increased every 10 min by 1.6 m/min until exhaustion. There was a reduction in total glutathione in the skeletal muscle of DEM treated animals compared to the control animals (P < 0.05). Within the control group, total glutathione was higher in the sedentary group compared to after exercise (P < 0.05). DEM treatment also significantly increased oxidative stress, as measured by increased plasma F2-isoprostanes (P < 0.05). Exercising animals given DEM showed a significantly greater increase in peroxisome proliferator activated receptor γ coactivator-1α (PGC-1α) mRNA compared to the control animals that were exercised (P < 0.05). This study provides novel evidence that by lowering the endogenous antioxidant glutathione in skeletal muscle and inducing oxidative stress through exercise, PGC-1α gene expression was augmented. These findings further highlight the important role of exercise induced oxidative stress in the regulation of mitochondrial biogenesis.

A factor analytical approach to the efficient futures market hypothesis

Most empirical evidence suggests that the efficient futures market hypothesis, henceforth referred to as EFMH, stating that spot and futures prices should cointegrate with a unit slope on futures prices, does not hold, a finding at odds with many theoretical models. This article argues that these results can be attributed in part to the low power of univariate tests, and that the use of panel data can generate more powerful tests. The current article can be seen as a step in this direction. In particular, a newly developed factor analytical approach is employed, which is very general and, in addition, free of the otherwise so common incidental parameters bias in the presence of fixed effects. The approach is applied to a large panel covering 17 commodities between March 1991 and August 2012. The evidence suggests that the EFMH cannot be rejected once the panel evidence has been taken into account. © 2014 Wiley Periodicals, Inc.

Currency overlay for global equity portfolios : cross-hedging and base currency

The effectiveness of a currency overlay hedge for a global equity portfolio can be significantly affected by changes in the base currency. Base currency changes have no significant effect on the hedged portfolio risk; however, they may substantially increase or decrease risk relative to the unhedged position. Australian (AUD) and Canadian (CAD) forwards provide effective cross-hedging, particularly in combination with one or two other currency hedges. Hedge effectiveness is significantly improved by allowing for natural hedges via a dynamic approach that captures structural change and permits under-hedging of currency exposures. © 2014 Wiley Periodicals, Inc.

In vitro response to functionalized self-assembled peptide scaffolds for three-dimensional cell culture

Nanomaterials are rich in potential, particularly for the formation of scaffolds that mimic the landscape of the host environment of the cell. This niche arises from the spatial organization of a series of biochemical and biomechanical signals. Self-assembling peptides have emerged as an important tool in the development of functional (bio-)nanomaterials; these simple, easily synthesized subunits form structures which present the properties of these larger, more complex systems. Scaffolds based upon these nanofibrous matrices are promising materials for regenerative medicine as part of a new methodology in scaffold design where a "bottom-up" approach is used in order to simulate the native cellular milieu. Importantly, SAPs hold the potential to be bioactive through the presentation of biochemical and biomechanical signals in a context similar to the natural extracellular matrix, making them ideal targets for providing structural and chemical support in a cellular context. Here, we discuss a new methodology for the presentation of biologically relevant epitopes through their effective presentation on the surface of the nanofibers. Here, we demonstrate that these signals have a direct effect on the viability of cells within a three-dimensional matrix as compared with an unfunctionalized, yet mechanically and morphologically similar system. © 2014 Wiley Periodicals, Inc.

An effective program design to support older workers with intellectual disability to participate individually in community groups

The foreshadowed increase of older people with intellectual disability has become a reality in many developed countries. As these adults age, improved quality of life can be achieved through applications of conjoint policy aims of inclusion and participation. A transition-to-retirement (TTR) program developed for employees of a large multisite disability employment service in Sydney, Australia, used these aims to effect successful partial retirement. The authors describe the program logic of the TTR, detailing its conceptual components as the first step to enabling it to be tested and replicated in other settings. The TTR program has three components: promoting the concept of retirement, laying the groundwork for inclusion of would-be retirees with intellectual disability in the community, and constructing the reality. The third component comprised five stages: planning, locating a group, mapping new routine, recruiting and training mentors, and monitoring and ongoing support. The project's participants were 24 older employees, who replaced 1 day a week of work with membership of a community group and were supported by mentors who facilitated involvement of the participants in their group. Data collected provided information on the implementation of the program, the time and costs expended, and challenges encountered. Key to the model was a coordinator, skilled in generic case management and specific disability interventions (such as active support), who collaborated with others to manage the program. The authors note that by detailing the program logic underpinning the TTR program, they have exposed the hidden work of supporting meaningful inclusion of people with intellectual disability in community groups and added to the limited stock of evidence-informed programs in this area. © 2014 International Association for the Scientific Study of Intellectual and Developmental Disabilities and Wiley Periodicals, Inc.

Effects of systemic hypoxia on human muscular adaptations to resistance exercise training

Hypoxia is an important modulator of endurance exercise-induced oxidative adaptations in skeletal muscle. However, whether hypoxia affects resistance exercise-induced muscle adaptations remains unknown. Here, we determined the effect of resistance exercise training under systemic hypoxia on muscular adaptations known to occur following both resistance and endurance exercise training, including muscle cross-sectional area (CSA), one-repetition maximum (1RM), muscular endurance, and makers of mitochondrial biogenesis and angiogenesis, such as peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), citrate synthase (CS) activity, nitric oxide synthase (NOS), vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1 (HIF-1), and capillary-to-fiber ratio. Sixteen healthy male subjects were randomly assigned to either a normoxic resistance training group (NRT, n = 7) or a hypoxic (14.4% oxygen) resistance training group (HRT, n = 9) and performed 8 weeks of resistance training. Blood and muscle biopsy samples were obtained before and after training. After training muscle CSA of the femoral region, 1RM for bench-press and leg-press, muscular endurance, and skeletal muscle VEGF protein levels significantly increased in both groups. The increase in muscular endurance was significantly higher in the HRT group. Plasma VEGF concentration and skeletal muscle capillary-to-fiber ratio were significantly higher in the HRT group than the NRT group following training. Our results suggest that, in addition to increases in muscle size and strength, HRT may also lead to increased muscular endurance and the promotion of angiogenesis in skeletal muscle.

Neuronal classification and distribution in the central nervous system of the female mud crab, Scylla olivacea

The mud crab, Scylla olivacea, is one of the most economically valuable marine species in Southeast Asian countries. However, commercial cultivation is disadvantaged by reduced reproductive capacity in captivity. Therefore, an understanding of the general and detailed anatomy of central nervous system (CNS) is required before investigating the distribution and functions of neurotransmitters, neurohormones, and other biomolecules, involved with reproduction. We found that the anatomical structure of the brain is similar to other crabs. However, the ventral nerve cord (VNC) is unlike other caridian and dendrobrachiate decapods, as the subesophageal (SEG), thoracic and abdominal ganglia are fused, due to the reduction of abdominal segments and the tail. Neurons in clusters within the CNS varied in sizes, and we found that there were five distinct size classes (i.e., very small globuli, small, medium, large, and giant). Clusters in the brain and SEG contained mainly very small globuli and small-sized neurons, whereas, the VNC contained small-, medium-, large-, and giant-sized neurons. We postulate that the different sized neurons are involved in different functions. Microsc. Res. Tech. 77:189–200, 2014. © 2013 Wiley Periodicals, Inc.
