Towards a Theory of Second Language Acquisition

In this paper, the author examines attempts at theory building within the field of Second Language Acquisition, particularly efforts to formulate a unified theory of SLA. He argues that such attempts have been largely futile and moreover, given the nature of the discipline itself, that efforts toward consensus –style theory building are misguided and possibly counter productive.

Some Elements of Australian Speech: Vowel Sounds

The increasing use of English as a means of global communication, often between non-native speakers, has led to wider exposure to, and awareness of, different varieties and accents of English. In this paper, the author, an Australian native speaker teaching English as a Foreign Language (EFL) in Thailand, attempts to highlight some of the features of Australian pronunciation which distinguish it from other varieties. In particular, it is contrasted with the British "prestige" variety Received Pronunciation (RP). The emphasis in the paper is on vowel sounds since these are often the elements of Australian pronunciation most easily distinguishable to the listener

The Taegeukgi and the Maple Leaf: The Pursuit of South Korean Export Markets by Atomic Energy Canada Limited

In the 1980’s Canada’s nuclear technology company, Atomic Energy Canada Limited (AECL), designed and attempted to sell a next-generation, small-scale nuclear reactor called the Slowpoke Energy System (SES). AECL pursued export markets for the SES, of which the most promising was South Korea. The SES project was forced to compete for funding and this necessitated the formation of partnerships with private and public sector agents in South Korea. AECL’s experience in South Korea suggests that crown corporations are more commercially oriented than established policy scholarship admits, and that in some cases competitive forces work to blunt innovation rather than reward it.Dans les années 1980, la société canadienne de technologie nucléaire, Énergie atomique du Canada limitée (EACL), conçoit et tente de mettre en marché une nouvelle génération de réacteur nucléaire de petite dimension appelée Slowpoke Energy System (SES). EACL cherche des marchés où exporter le SES, et entrevoit des avenues prometteuses en Corée du Sud. Le projet SES doit toutefois compétitionner pour le financement, ce qui nécessite la formation de partenariats avec des agents des secteurs privés et publics de la Corée du Sud. L’expérience d’EACL en Corée du Sud suggère que les sociétés de la couronne sont plus orientées vers le commerce que ne l’admet généralement la recherche académique sur les politiques d’État, et que dans certains cas, les forces de la compétition contribuent davantage à émousser l’innovation plutôt qu’à la récompenser

Selected Materials From A Study of The Worm Ouroboros

After a brief précis of Eddison’s life, the author discusses the genre of The Worm Ouroboros, basing most of his arguments on Frye’s Anatomy of Criticism. Following is an examination of the tale’s sources, most notably elements from the Norse sagas, The Travels of Sir John Mandeville, and Orlando Furioso

A Review of Agent Emotion Architectures

This paper attempts to highlight some of the research that has been conducted worldwide in the area of computational models of emotions, with a particular emphasis on agent emotions suitable for simulations and games. The intended outcome is to both review some of the more prominent research in the field, and to also ascertain the level of formal psychology that may underpin such work with a view to proposing that there is scope for an architecture built from the ground up, that arises from non-conflicting theories of emotion

Incidence of fires and related injuries after giving out free smoke alarms: cluster randomised controlled trial.

OBJECTIVE: To measure the effect of giving out free smoke alarms on rates of fires and rates of fire related injury in a deprived multiethnic urban population. DESIGN: Cluster randomised controlled trial. SETTING: Forty electoral wards in two boroughs of inner London, United Kingdom. PARTICIPANTS: Primarily households including elderly people or children and households that are in housing rented from the borough council. INTERVENTION: 20 050 smoke alarms, fittings, and educational brochures distributed free and installed on request. MAIN OUTCOME MEASURES: Rates of fires and related injuries during two years after the distribution; alarm ownership, installation, and function. RESULTS: Giving out free smoke alarms did not reduce injuries related to fire (rate ratio 1.3; 95% confidence interval 0.9 to 1.9), admissions to hospital and deaths (1.3; 0.7 to 2.3), or fires attended by the fire brigade (1.1; 0.96 to 1.3). Similar proportions of intervention and control households had installed alarms (36/119 (30%) v 35/109 (32%); odds ratio 0.9; 95% confidence interval 0.5 to 1.7) and working alarms (19/118 (16%) v 18/108 (17%); 0.9; 0.4 to 1.8). CONCLUSIONS: Giving out free smoke alarms in a deprived, multiethnic, urban community did not reduce injuries related to fire, mostly because few alarms had been installed or were maintained

An integrated carbon and oxygen isotope approach to reconstructing past environmental variability in the northeast Atlantic Ocean

The combined influence of temperature and the isotopic composition of the seawater (δ18Ow) often precludes the use of oxygen isotope (δ18O) records, derived from marine carbonates, to reconstruct absolute seawater temperatures, without the application of an independent δ18Ow proxy. Here we investigate the application of carbon isotope records (δ13Cshell), derived from the long-lived marine bivalve Glycymeris glycymeris, as a proxy for δ18Ow variability. Our analyses indicate G. glycymeris δ13Cshell data derived from growth increments >20 years of age contain strong ontogenetic trends (−0.013‰ yr−1, R = 0.98, P < 0.001, N = 51). These analyses demonstrate that, coupled with the ontogenetic trends, 54% of the variability in G. glycymeris δ13Cshell records can be explained by a combination of the marine Suess effect and physical (salinity and riverine input) and biological processes (primary production). The application of these δ13Cshell data in conjunction with co-registered δ18Oshell and growth increment width series, each of which have been shown to be sensitive to seawater temperature and primary productivity respectively, can therefore provide new insights into past environmental variability and help constrain uncertainties on reconstructions of past seawater temperature variability

Step 4: stick or twist? A review of asthma therapy

Many people with asthma do not achieve disease control, despite bronchodilators and inhaled corticosteroid therapy. People with uncontrolled asthma are at higher risk of an asthma attack and death, with mortality rates estimated at 1000 deaths/ year in England and Wales. The recent National Review of Asthma Deaths (NRAD) report, ‘Why asthma still kills’, recommended that patients at step 4 or 5 of the British Thoracic Society/Scottish Intercollegiate Guidelines Network (BTS/SIGN) guidance must be referred to a specialist asthma service. This article reviews the 2014 evidence base for therapy of asthma patients at BTS/SIGN step 4 of the treatment cascade, in response to key findings of the NRAD report and lack of preferred treatment option at this step

The impact of azithromycin therapy on the airway microbiota in asthma

There is interest in the use of macrolide antibiotics in asthma. Macrolides have been shown to improve airway hyperresponsiveness (AHR) and measures of airway inflammation.The degree of AHR may relate to the microbiota present in the airways, with a recent study reporting that patients with asthma with a significant improvement in AHR following treatment with clarithromycin had a higher bacterial diversity prior to treatment. To our knowledge, the impact on the asthmatic airway microbiota of an antibiotic has not been reported and we therefore set out to establish if macrolide therapy was associated with a change in airway microbiota in asthma

Comparing the ecological impacts of native and invasive crayfish: could native species' translocation do more harm than good?

Biological invasions are a principal threat to global biodiversity. Omnivores, such as crayfish, are among the most important groups of invaders. Their introduction often results in biodiversity loss, particularly of their native counterparts. Managed relocations of native crayfish from areas under threat from invasive crayfish into isolated ‘ark sites’ are sometimes suggested as a conservation strategy for native crayfish; however, such relocations may have unintended detrimental consequences for the recipient ecosystem. Despite this, there have been few attempts to quantify the relative impacts of native and invasive crayfish on aquatic ecosystems. To address this deficiency we conducted a meta-analysis on the effects of native and invasive crayfish on nine ecosystem components: decomposition rate, primary productivity, plant biomass, invertebrate density, biomass and diversity, fish biomass and refuge use, and amphibian larval survival. Native and invasive crayfish significantly reduced invertebrate density and biomass, fish biomass and amphibian survival rate and significantly increased decomposition rates. Invasive crayfish also significantly reduced plant biomass and invertebrate diversity and increased primary productivity. These results show that native and invasive crayfish have wide-ranging impacts on aquatic ecosystems that may be exacerbated for invasive species. Subsequent analysis showed that the impacts of invasive crayfish were significantly greater, in comparison to native crayfish, for decomposition and primary productivity but not invertebrate density, biomass and diversity. Overall, our findings reconfirm the ecosystem altering abilities of both native and invasive crayfish, enforcing the need to carefully regulate managed relocations of native species as well as to develop control programs for invasives
