Carbon taxation, prices and inequality in Australia

from the combustion of fossil fuels, has led to proposals for non-market mechanisms such as regulation, and market mechanisms such as tradable emissions permits and carbon taxes, in order to reduce emissions. Market methods are usually preferred in terms of efficiency, and the carbon tax is deemed as being the easiest to implement and monitor. Owen (1992, p. 4)compares carbon taxes with other instruments; Pearce (1991) provides a summary of the advantages and disadvantages of a carbon tax; and Dower and Zimmerman (1992) compare the merits of carbon taxes and tradable emissions permits. A carbon tax would affect the price of fossil fuels and thus consumer prices,both directly for fuels and indirectly for manufactured goods. These price changes would alter the levels of final demands, and therefore fossil fuel use and aggregate carbon dioxide emissions. This paper investigates the orders of magnitude of a carbon tax required to reduce carbon dioxide emissions in Australia such that the Toronto target is met; this requires a reduction in emissions of 20 per cent of 1988 levels by 2005. The paper also examines the

Unfenced Borders Cause Differences in Vegetation and Fauna Between Protected and Unprotected Areas in a Tropical Savanna

Protected areas generally occur within a matrix of intensively human-modified landscapes. As a way to maintain the biodiversity in these areas, enclosure by fencing is often preferred. This strategy, however, is costly and little is known about the effectiveness of the alternative of unfenced borders on the vegetation and fauna. The objectives of this study are to assess whether there is a distinct difference in biodiversity and composition of plants and mammals between the protected Lake Mburo National Park and the adjacent ranchlands across an unfenced border and to determine the associations between vegetation and faunal species over the same border. We recorded herbaceous vegetation, woody vegetation, and mammal species composition in plots 300 to 500 m away from the border both inside the protected area and in the adjacent ranchlands. The species composition of herbs and mammals in the protected area differ from the adjacent ranchlands, but there is no difference for trees and shrubs. After accounting for land-use type, distance from the border did not significantly account for any additional variation. We also find a correlation between the species composition of vegetation and fauna. Our results suggest that unfenced borders around protected areas create a clear effect.publishedVersio

Mother-Tongue Based (MTB) Schooling: A Key for Transforming Early Childhood Education for Future Generation in Nigeria

The study sought to determine the extent of usage of Igbo Language as a medium of instruction and interaction in the lower basic classes in Enugu North Education Zone, Enugu State, Nigeria. Four research questions guided the study. The design was a descriptive survey. The population consisted of 2069 teachers (198 Head teachers and 1,871 Classroom teachers) in Enugu North Education zone of Enugu state, public and private schools inclusive. The sample was 200 teachers (50 Head teachers and 150 Class teachers) drawn from the population using stratified random sampling technique. The instrument used for data collection was researchers developed questionnaire titled “Mother-Tongue Based Schooling Questionnaire” (MTBSQ) which was face validated by experts in Igbo Language and Measurement and Evaluation from Federal College of Education, Kotangora, Niger State. The reliability estimate of MTBSQ established using Pearson’s co-efficient formula was 0.86.  Findings indicated very low extent of the use of mother tongue (Igbo Language) as a medium of instruction and interaction; schools and parents preferred the use of English Language (L2) as a medium of instruction and interaction; and indigenous materials and textbooks in mother tongue were not available or used for instruction. By educational implication, this is a negation of the National policy stipulation on the usage of mother-tongue for instruction in Nigerian schools.  The researchers therefore recommended that Government should lay emphasis on total implementation of the National Policy on Education with particular reference to usage of mother-tongue as a medium of instruction in pre-primary and primary schools in Nigeria. Also, parents and care-givers should be educated on the need for them to interact with children in their mother-tongue. Keywords: early childhood education, future generation, mother tongue.

Appendicectomies in Albanians in Greece: outcomes in a highly mobile immigrant patient population

BACKGROUND: Albanian immigrants in Greece comprise a highly mobile population with unknown health care profile. We aimed to assess whether these immigrants were more or less likely to undergo laparotomy for suspected appendicitis with negative findings (negative appendicectomy), by performing a controlled study with individual (1:4) matching. We used data from 6 hospitals in the Greek prefecture of Epirus that is bordering Albania. RESULTS: Among a total of 2027 non-incidental appendicectomies for suspected appendicitis performed in 1994-1999, 30 patients with Albanian names were matched (for age, sex, time of operation and hospital) to 120 patients with Greek names. The odds for a negative appendicectomy were 3.4-fold higher (95% confidence interval [CI], 1.24-9.31, p = 0.02) in Albanian immigrants than in matched Greek-name subjects. The difference was most prominent in men (odds ratio 20.0, 95% CI, 1.41-285, p = 0.02) while it was not formally significant in women (odds ratio 1.56, 95% CI, 0.44-5.48). The odds for perforation were 1.25-fold higher in Albanian-name immigrants than in Greek-name patients (95% CI 0.44- 3.57). CONCLUSIONS: Albanian immigrants in Greece are at high risk for negative appendicectomies. Socioeconomic, cultural and language parameters underlying health care inequalities in highly mobile immigrant populations need better study

Impact of Haptic Feedback in High Latency Teleoperation for Space Applications

Remote manipulation is a key enabler for upcoming space activities such as in-orbit servicing and manufacture (IOSM). However, due to the large distances involved, these systems encounter unavoidable signal delays which can lead to poor performance and users adopting a disjointed, ‘move-and-wait’ style of operation. We use a robot arm teleoperated with a haptic controller to test the impact of haptic feedback on delayed (up to 2.6 s: Earth-Moon communications) teleoperation performance for two example IOSM-style tasks.This user study showed that increased latency reduced performance in all of metrics recorded. In real-time teleoperation, haptic feedback showed improvements in success rate, accuracy, contact force, velocity, and trust, but, of these, only the improvements to contact forces and moving velocity were also seen at higher latencies. Accuracy and trust improvements were lost, or even reversed, at higher latencies. Results varied between the two tasks, highlighting the need for further research into the range of task types to be encountered in teleoperated space activities. This study also provides a framework by which to explore how features other than haptic feedback can impact both performance and trust in delayed teleoperatio

Cognitive–behavioural therapy for adult attention-deficit hyperactivity disorder:a proof of concept randomised controlled trial

Objective: To investigate efficacy, patient acceptability and feasibility of formulation-based cognitive–behavioural therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD). NICE guidelines for adult ADHD recommend further research into psychological treatments. Method: Sixty participants with adult ADHD were randomly allocated to treatment as usual (TAU) vs. TAU plus up to 16 sessions of individual formulation-based CBT for ADHD. Results: Adding formulation-based CBT to TAU for ADHD significantly improved ADHD symptoms on the Barkley Current Symptoms Scale and scores on the Work and Social Adjustment Scale. Adjusted effect sizes (ES) were 1.31 and 0.82 respectively. There were also significant improvements on secondary outcomes including independently evaluated clinical global improvement, self-rated anxiety, depression, global distress and patient satisfaction (adjusted effect sizes 0.52–1.01). Conclusions: This is the first randomised controlled trial to provide preliminary evidence of efficacy and acceptability of individual formulation-based CBT for ADHD when added to TAU over TAU alone. This approach now needs to be tested in a larger multicentred randomised controlled trial.</p

Self-reported quality of care for older adults from 2004 to 2011: a cohort study

Background: little is known about changes in the quality of medical care for older adults over time. Objective: to assess changes in technical quality of care over 6 years, and associations with participants' characteristics. Design: a national cohort survey covering RAND Corporation-derived quality indicators (QIs) in face-to-face structured interviews in participants' households. Participants: a total of 5,114 people aged 50 or more in four waves of the English Longitudinal Study of Ageing. Methods: the percentage achievement of 24 QIs in 10 general medical and geriatric clinical conditions was calculated for each time point, and associations with participants' characteristics were estimated using logistic regression. Results: participants were eligible for 21,220 QIs. QI achievement for geriatric conditions (cataract, falls, osteoarthritis and osteoporosis) was 41% [95% confidence interval (CI): 38–44] in 2004–05 and 38% (36–39) in 2010–11. Achievement for general medical conditions (depression, diabetes mellitus, hypertension, ischaemic heart disease, pain and cerebrovascular disease) improved from 75% (73–77) in 2004–05 to 80% (79–82) in 2010–11. Achievement ranged from 89% for cerebrovascular disease to 34% for osteoarthritis. Overall achievement was lower for participants who were men, wealthier, infrequent alcohol drinkers, not obese and living alone. Conclusion: substantial system-level shortfalls in quality of care for geriatric conditions persisted over 6 years, with relatively small and inconsistent variations in quality by participants' characteristics. The relative lack of variation by participants' characteristics suggests that quality improvement interventions may be more effective when directed at healthcare delivery systems rather than individuals

Diagnosis of Ovarian Cancer Using Decision Tree Classification of Mass Spectral Data

Recent reports from our laboratory and others support the SELDI ProteinChip technology as a potential clinical diagnostic tool when combined with n-dimensional analyses algorithms. The objective of this study was to determine if the commercially available classification algorithm biomarker patterns software (BPS), which is based on a classification and regression tree (CART), would be effective in discriminating ovarian cancer from benign diseases and healthy controls. Serum protein mass spectrum profiles from 139 patients with either ovarian cancer, benign pelvic diseases, or healthy women were analyzed using the BPS software. A decision tree, using five protein peaks, resulted in an accuracy of 81.5% in the cross-validation analysis and 80% in a blinded set of samples in differentiating the ovarian cancer from the control groups. The potential, advantages, and drawbacks of the BPS system as a bioinformatic tool for the analysis of the SELDI high-dimensional proteomic data are discussed
