Words by convention

Existing metasemantic projects presuppose that word- (or sentence-) types are part of the non-semantic base. We propose a new strategy: an endogenous account of word types, that is, one where word types are fixed as part of the metasemantics. On this view, it is the conventions of truthfulness and trust that ground not only the meaning of the words (meaning by convention) but also what the word type is of each particular token utterance (words by convention). The same treatment extends to identifying the populations through which the conventions prevail. We consider whether this proposal leads to new underdetermination challenges for metasemantics, and make a case that it does not

The use of Information and Communication Technology (ICT) by Preschool and Kindergarten Educators

This study has examined Preschool and Kindergarten educators’ perspectives on the use of Information and Communication Technology (ICT) to support learning in the classroom. The purpose was to determine the factors that influenced educators’ use of ICTs in their practice, their views on whether ICTs enhances children’s learning and their value of ICT training. The data revealed three themes herewith detailed in hierarchical order, that educators’ perceptions were dependent on the tools’ effectiveness and applicability in their program; that there are varied perspectives on what constituted a technological barrier and a technological impact; and that participants’ concerns were based on their overall perception of ICTs. However, although there were factors which affected educators’ decisions on whether or not to use ICTs in their programs, the data also suggested that educators’ level of interest in the use of ICTs in the classroom was thought to be the most influential factor in educators’ overall decision to use ICTs in their program.https://source.sheridancollege.ca/fahcs_student_capstones_hbecl/1005/thumbnail.jp

Behaviour and accidents in young children and adolescents

The Mater-University Study of Pregnancy recruited a cohort of 8,458 Brisbane women during pregnancy. Subsequent follow-ups of mother and child occurred a few days, 6 months, 5 years and 14 years after birth, with the collection of a wide range of biological, sociological and behavioural information as well as measures of mental and physical health. In anticipation of a further cohort follow-up (funded by CARRS-Q) aimed specifically at examining risk-taking behaviour and road crashes in young drivers, the present paper examines the relationship between child and adolescent behaviour and the occurrence of accidents. This indicates that children with behaviour problems, particularly social and attentional disorders at age 5 years are nearly twice as likely to have had an accident in the past three months. While there is some evidence of continuity of accident occurrence (27% of children whose mother’s reported an accident at age 5 years also were also reported to have had an accident requiring medical attention in the last year) this association was weak. Behaviour problems, as measured by the Child Services, police or Juvenile Aid Bureau at age 14 also predict accident occurrence at age 14. ‘Binge drinking’ (consumption of seven or more alcoholic drinks at a time), while rare in this sample (2%) was associated with a doubling of accident risk. The next phase of MUSP will involve administering a questionnaire focused on risk taking behaviour to adolescents, followed up by later record linkage to accident reports and medical records to obtain end-points of road crashes and accident morbidity

Development and application of imaging techniques for the investigation of dentinal hypersensitivity

The overall aim of this thesis is to examine the underlying physical basis of dentinal hypersensitivity and to assess methods of treating this cause using imaging techniques. The scanned probe microscopy (SPM) techniques are then extended to the study of carbon-based electrode surfaces, as described in the final chapter. The use of scanning electrochemical microscopy (SECM), combined with in situ pressure-time measurements, is described as a means to investigate the flow of fluid through human and bovine dentine, and the subsequent effect of occlusion treatments on this flow. Scanning Ion Conductance Microscopy (SICM) is also introduced as a technique for imaging dentine, with instrument design and development described, and also calibration of the technique. Laser scanning confocal microscopy (LSCM) coupled to a constant volume flowpressure measuring system is introduced as a new technique for the quantitative measurement of fluid flow across porous materials. The methodology described herein firstly allows a ready assessment of the general efficacy of treatments via hydraulic permeability measurements. Second, LSCM images allow the nature of the flow process and the mode of action of the treatments to be revealed at high spatial resolution. For the particular case of dentine, we demonstrate how the method allows candidate treatments to be compared and assessed. To complement the studies into dentinal hypersensitivity, microscopic dissolution of bovine enamel is investigated. This chapter describes a novel approach, based on SECM, to promote the localised dissolution of bovine enamel, effected by the application of a proton flux to the enamel surface from a UME positioned within 5 μm of the surface, in aqueous solution. The approach results in a well-defined “acid challenge” yielding well-defined etch pits that were characterised using light microscopy and white light interferometry. The effect of etching in the presence of lactate is considered, as is the effect of treating the enamel samples with sodium fluoride prior to etching. The approach described is amenable to mass transport modelling, allowing quantitative interpretation of etch features. The techniques developed throughout the thesis are applied to the investigation of two types of carbon electrodes: boron-doped diamond (BDD) and highly ordered pyrolytic graphite (HOPG). Heterogeneities in the electroactivity of these substrates are explored.A scanning micropipet contact method (SMCM) is described which promises wide-ranging application in imaging and quantifying electrode activity at high spatial resolution

The mental health of Filipino-born women 5 and 14 years after they have given birth in Australia: a longitudinal study

It has been suggested that Filipino brides may be 'at risk' of social isolation and mental health impairment after migrating to Australia to marry Australian men. This paper examines the mental health of a cohort of Filipino and Australian-born women who became mothers in Australia, and investigates the relationship between place of birth, social network size and symptoms of poor mental health. The data was taken from the Mater-University of Queensland Study of Pregnancy (MUSP), a longitudinal study of mothers and children instigated in 1981. Symptoms of anxiety and depression and social network size were assessed at their first clinic visit (FCV), and followed up at 5 and 14 years. Filipino-born mothers had smaller social networks at the birth of their child, and reported more symptoms of anxiety arid depression at FCV and 5 years follow-up (F/U), but did not differ from their Australian counterparts 14 years later. We conclude that Filipino-born migrants experience greater distress and poorer social networks than Australian-born mothers in the early years after they have given birth to a child in Australia. Further, that over a period of time, the decrease in mental health symptoms indicates the adaptation of Filipino-born women to their new environment

Temperature enhanced effects of ozone on cardiovascular mortality in 95 large US communities, 1987-2000 - assessment using the NMMAPS data

A few studies examined interactive effects between air pollution and temperature on health outcomes. This study is to examine if temperature modified effects of ozone and cardiovascular mortality in 95 large US cities. A nonparametric and a parametric regression models were separately used to explore interactive effects of temperature and ozone on cardiovascular mortality during May and October, 1987-2000. A Bayesian meta-analysis was used to pool estimates. Both models illustrate that temperature enhanced the ozone effects on mortality in the northern region, but obviously in the southern region. A 10-ppb increment in ozone was associated with 0.41 % (95% posterior interval (PI): -0.19 %, 0.93 %), 0.27 % (95% PI: -0.44 %, 0.87 %) and 1.68 % (95% PI: 0.07 %, 3.26 %) increases in daily cardiovascular mortality corresponding to low, moderate and high levels of temperature, respectively. We concluded that temperature modified effects of ozone, particularly in the northern region
