Using Valsiner

Students develop within rich, complex cultural community settings involving teachers and the environmental surrounds. To investigate the multiple perspectives in such a teaching and learning setting a suitable framework incorporating sociocultural practices is needed. The developmental works of Valsiner are proposed here which, it will be argued, assists in the identification and analysis of developmental issues. The application of the theoretical framework presented in this paper is exemplified in the development of numeracy in a 1st year nursing progra

Students using digital technologies to produce screencasts that support learning in mathematics

This paper reports on research of student produced screencasts to support learning. Participants in a Mathematics for Teachers course were asked to create and peer critique screencasts to explain concepts (year 4 to 9 level). They were also asked about their experience with screencasting and its impact on their own teaching and learning. This paper will discuss preliminary results of a pre-survey and highlight features of initial screencasts and their critiques. The paper concludes with an outline of future directions

Reframing e-assessment: building professional nursing and academic attributes in a first year nursing course

This paper documents the relationships between pedagogy and e-assessment in two nursing courses offered at the University of Southern Queensland, Australia. The courses are designed to build the academic, numeracy and technological attributes student nurses need if they are to succeed at university and in the nursing profession. The paper first outlines the management systems supporting the two courses and how they intersect with the e-learning and e-assessment components of course design. These pedagogical choices are then reviewed. While there are lessons to be learnt and improvements to be made, preliminary results suggest students and staff are extremely supportive of the courses. The e-assessment is very positively received with students reporting increased confidence and competency in numeracy, as well as IT, academic, research and communication skills

Examining undergraduate student retention in mathematics using network analysis and relative risk

Higher education faces challenges in retaining students who require a command of numeracy in their chosen field of study. This study applies an innovative combination of relative risk and social network analysis to enrolment data of a single cohort of commencing students from an Australian regional university. Relative risk, often used in epidemiology studies, is used to strategically investigate whether first year mathematics subjects at the university demonstrated a higher risk of attrition when compared to other subjects offered in the first year of study. The network analysis is used to illustrate the connections of those mathematics subjects, identifying service subjects through their multiple connections. The analysis revealed that attrition rates for eight of the nine subjects were within acceptable limits, and this included identified service subjects. The exception highlighted the issue of mathematics competencies in this cohort. This combined analytical technique is proposed as appropriate for use when investigating attrition and retention at faculty and institutional levels, including the determination of levels of intervention and support for any subject

A Model to Evaluate Economic Effects of Fishery Management Measures: How Would a Change in Total Allowable Catch for Monterey Groundfish Affect the Local Economy?

The research question addressed by this thesis is: if a modification to the Magnuson-Stevens Fishery Conservation and Management Act enabled an increase in Total Allowable Catch for a single species in the US West Coast groundfish fishery, what would be the direct and indirect economic effects on Monterey County, California? I used primary and secondary industry sources to build an Input/Output table reflecting the Monterey County economy, then calculated economic multipliers from this Input/Output table. I then calculated the likely increase in catch of relevant species (the species of focus and those that co-occur with it) and used recent ex-vessel prices to arrive at the likely economic effect. Various scenarios were explored: the base case was a simple aggregation of industry sector data from federal government sources; additional cases included a different aggregation of industry sectors, addition of industry transaction data from the Pacific Fisheries Information Network and addition of survey data from fishermen and processors. Counting only direct and indirect effects of an increase in commercial catch, a 10% increase in Total Allowable Catch of bocaccio rockfish could result in effects ranging from $250,000 to over$1,000,000 per annum for the fishing community in Monterey County. While this is a straightforward benefit, the costs of ecosystem effects would need to be quantified and evaluated for a thorough analysis of the merit of increasing bocaccio TAC

Women MPs from Northern Ireland: Challenges and Contributions, 1953–2020.

This article investigates women’s representation as Northern Ireland (NI) MPs in the House of Commons since 1953. The central argument of the study is that the political and cultural positions dominant at the formation of NI in the early 20th century reverberate through the generations and continue to inform women’s political under-representation today. The article provides an historical context for women’s political and public participation from the 1950s, highlighting the gendered political culture in which this engagement took place. It examines the additional freezing effect of the ethno-national conflict on women’s civic and political involvement from the 1970s–1990s. In terms of women’s Westminster contributions, the article focuses on the period following the 1998 Good Friday/Belfast agreement and details the extent of women’s candidacies in general elections. It highlights their participation in parliamentary voting, and some of the issues to which they have contributed. The study shows the influence of a conservative, gendered political culture on the issues that have engaged women MPs from Northern Ireland. The article concludes that Northern Ireland’s privileging of male power continues to frame the political agendas and work of women MPs

Catalytic cracking of jet propellant-10 : for Pulse detonation engine applications

Le carburant hydrocarbure JP-10 est étudié comme agent propulsif destiné aux moteurs à détonation ainsi qu’à d’autres applications concernant les vols à vitesses élevées. La précraquage catalytique du JP-10 pourrait produire un mélange d’oléfines légères plus facile à détoner. Un mélange d’hydrocarbures aliphatiques, pour la plupart légers, présente l’avantage d’être moins enclin à la carbonisation que des mélanges comportant de fortes teneurs en hydrocarbures aromatiques. Cette réaction endothermique de précraquage offre le même potentiel que celui d’un puits de chaleur trouvé dans des applications de vols à vitesses élevées pour lesquelles toute hausse de la masse du système de refroidissement contrevient à une plus grande efficacité du moteur. Plusieurs essais de craquage catalytique hétérogène furent réalisés à l’aide d’un réacteur tubulaire et les gaz produits analysés par GC/MS et par GC. Deux formes de zéolithe nanocristalline (n) ZSM-5(24h) et nZSM-5 (6h) et trois formes de silico-aluminophosphate SAPO-5A, SAPO-5B et SAPO-11 furent testées. SAPO-5 et nZSM-5(24h) apparaissent être les candidats les plus propices au précraquage du JP-10. Ces dernières ont permis de convertir plus de 90 % de JP-10 en un mélange d’hydrocarbures principalement composé de molécules en C4 et moins (C3 à C1). nZSM-5(24h) ont procuré le plus petit rapport de masse de carbone, CR (C5+:C4−), à des températures situées entre 350 oC et 450 oC et le taux de conversion le plus élevé à des températures supérieures à 500 oC. SAPO-5A & B ont présenté le taux de conversion le plus élevé mais le plus petit CR entre 400 oC et 500 oC.The hydrocarbon jet-fuel, JP-10, is being studied as a possible propellant for the Pulse Detonation Engine (PDE) and other high-speed flight applications. Catalytic pre-cracking of JP-10 could provide a more easily detonated mixture of light olefin products. A mixture of mostly light hydrocarbons has the added benefit of being less prone to coking than a product mixture heavy in aromatics. This endothermic reaction also offers potential as a heat sink in high-speed flight applications where the extra weight of an onboard cooling system would hinder engine efficiency. Several heterogeneous catalytic cracking tests have been done using a Bench Top Tubular Reactor and the products were analyzed with GC/MS and GC. Two forms of nanocrystalline zeolites, nZSM-5(24h) and nZSM-5(6h), and three forms of silico-alumino-phosphates, SAPO-5A, SAPO-5B, and SAPO-11 successfully catalyzed the cracking of JP-10; however, SAPO-5 and nZSM-5(24h) have proven to be the most promising catalyts. Both catalysts converted over 90 % of JP-10 (∼ 3s residence time) into a mixture of hydrocarbon products consisting mainly of C4 and lower chain hydrocarbons (C3 to C1). nZSM-5(24h) demonstrated the lowest carbon mass ratio, CR (C5+:C4−), between 350 oC and 450 oC and the highest conversion rates above 500 oC. SAPO-5A & B demonstrated the highest conversion rates and the lowest CR between 400 oC and 500 oC

Understanding student experiences in university learning centres

This paper discusses a conceptual framework, based on Valsiner's human development theory, to assist in the identification and analysis of learning change issues. Learning change is particularly important in a student's first year and often observed in Learning Centres. The hub of this framework is analysing micro-processes made explicit by a sequence of student actions within a rich field of stimuli. The paper argues that the theory provides a useful tool to investigate the way adult learners think and develop, which in turn enhances educational practice in the context of Learning Centres at university
