The new generation of e-learners: Who is thinking of the children?

Young e-Learners of the 21st Century are currently 4-5 years old. They are sitting at computers for hours on end, playing games that utilize the insidious cognitive learning strategies devised by psychologists involving `Operant Conditioning¿. They are subtly and subliminally encouraged to believe that killing and decapitating a small cute flying dragon has nothing to do with reality. At 6 years of age they are accessing information through human-computer interaction (HCI) (Preece, 1994), hyper-linking through virtual cyber space and integrating multimedia texts of unknown origins to find material for a school project. They sit in non-ergonomically designed furniture, motionless for hours concentrating on bright colourful screens designed to capture, conquer and suppress the physical activity that is required to develop growing bodies. Who is looking after the children of the future? Do instructional designers consider the complex interaction of learning styles of human beings? Whose responsibility is it to design, develop and mass-produce web-based educational systems (WBES) that actually take into consideration the physical, cognitive, educational and social needs of the new generation of e-Learners

Influences on teachers' judgements of students' literacy development in a Victorian context

The research presented in this thesis investigates the influences on teachers' judgements of students' literacy development in a Victorian (Australia) context. By establishing the study within the paradigm known as constructivism (Guba & Lincoln, 1994) using constructivist (naturalistic) inquiry and qualitative methods of data collection (Denzin & Lincoln, 1994), the study describes through constructive, interpretive analysis the influences on teachers' decision making processes. By utilising the strengths of ethnographic participation an non-participation observation (Goetz & LeCompte, 1984), purposefully selecting case study school sites and participating teachers (Patton, 1990), and using the teachers' voice the influences on teachers' judgements of students' literacy development have been investigated through inductive analysis. The literature review examines the diversity in the conceptualisation of the concept literacy, describes three of the major views regarding the historical and current theoretical perspectives underpinning English language learning, and presents an analysis of current literacy learning continua. The review focuses the study on a significant gap in the information pertaining to influences on teachers' decision making processes. The research investigates the complexities of teachers' decision making processes in the formation of literacy judgements. The data collection involved three school sites in metropolitan Melbourne, Victoria, Australia. The three case studies centred on three main teachers. To facilitate the triangulation of information additional data sources were used: key informant interviews; curriculum and policy documents and classroom and student artefacts. Seven spheres of influence emerged from the data in this study. These spheres are identified as internalised reflective knowledge, assessment strategy selection, external considerations, dissemination, peer power, standards and macro political context. Recommendations for enhancing educational practice flow from the thesis; they have most relevance to teachers and principals in the field, educational policy makers, and to tertiary educators involved in educational change. This study augments the research pertaining to literacy assessment and reporting practices and to understanding of influences on teachers' judgemental processes

Religiosity and Sexual Activity Among Older Adolescents

This study investigates religiosity, sexual activity, and sexual permissiveness among older adolescents. Eighty-two college students completed a survey that measured religiosity, sexual permissiveness, self-esteem, frequency of recent sexual encounters, and motivators for sexual activity or abstinence. Guilt, prayer, organized religious activity, and religious well-being predicted fewer sexual encounters. Orthodox beliefs, participation in organized religious activities, and highly-rated importance of faith predicted less permissive sexual attitudes. We conclude that guilt and religious activity can be good motivators for decreasing sexual encounters. We recommend that health practitioners encourage participation in religious activity among adolescents

The life course design for transitional labour market research

This paper draws on research that documents the work, financial and personal benefits, and skill trajectories of trade and bachelor graduates' for the 10 years after completion of their initial education. The primary aim of the project is to better understand how people draw on their initial education and training. We suggest that while there is some value in using quantitative methods, one of our key objectives has been to develop a qualitative or interpretive research design that allows a better understanding why and how workers seek the employment they do, why they pursue promotion or acquire additional skills and why they change their occupational careers. We argue in this paper that use of an interpretive approach provides rich in-depth data that can be used to follow the decision-making steps taken by people as they proceed through their working lives. In this paper, we consider the benefits methodologically and conceptually of adopting what is referred to as a life-course research design

Use of Urinary Pregnanediol 3-glucuronide to Confirm Ovulation

Objective Urinary hormonal markers may assist in increasing the efficacy of Fertility Awareness Based Methods (FABM). This study uses urinary pregnanediol-3a-glucuronide (PDG) testing to more accurately identify the infertile phase of the menstrual cycle in the setting of FABM. Methods Secondary analysis of an observational and simulation study, multicentre, European study. The study includes 107 women and tracks daily first morning urine (FMU), observed the changes in cervical mucus discharge, and ultrasonography to identify the day of ovulation over 326 menstrual cycles. The following three scenarios were tested: (A) use of the daily pregnandiol-3a-glucuronide (PDG) test alone; (B) use of the PDG test after the first positive urine luteinizing hormone (LH) kit result; (C) use of the PDG test after the disappearance of fertile type mucus. Two models were used: (1) one day of PDG positivity; or (2) waiting for three days of PDG positivity before declaring infertility. Results After the first positivity of a LH test or the end of fertile mucus, three consecutive days of PDG testing over a threshold of 5 μg/mL resulted in a 100% specificity for ovulation confirmation. They were respectively associated an identification of an average of 6.1 and 7.6 recognized infertile days. Conclusions The results demonstrate a clinical scenario with 100% specificity for ovulation confirmation and provide the theoretical background for a future development of a competitive lateral flow assay for the detection of PDG in the urine

A Comparison of the Ovulation Method With the CUE Ovulation Predictor in Determining the Fertile Period

The purpose of this study was to compare the CUE Ovulation Predictor with the ovulation method in determining the fertile period. Eleven regularly ovulating women measured their salivary and vaginal electrical resistance (ER) with the CUE, observed their cervical-vaginal mucus, and measured their urine for a luteinizing hormone (LH) surge on a daily basis. Data from 21 menstrual cycles showed no statistical difference (T= 0.33, p= 0.63) between the CUE fertile period, which ranged from 5 to 10 days (mean = 6.7 days, SD = 1.6), and the fertile period of the ovulation method, which ranged from 4 to 9 days (mean = 6.5 days, SD = 2.0). The CUE has potential as an adjunctive device in the learning and use of natural family planning methods

A systematic review of the evidence for single stage and two stage revision of infected knee replacement

BACKGROUND: Periprosthetic infection about the knee is a devastating complication that may affect between 1% and 5% of knee replacement. With over 79 000 knee replacements being implanted each year in the UK, periprosthetic infection (PJI) is set to become an important burden of disease and cost to the healthcare economy. One of the important controversies in treatment of PJI is whether a single stage revision operation is superior to a two-stage procedure. This study sought to systematically evaluate the published evidence to determine which technique had lowest reinfection rates. METHODS: A systematic review of the literature was undertaken using the MEDLINE and EMBASE databases with the aim to identify existing studies that present the outcomes of each surgical technique. Reinfection rate was the primary outcome measure. Studies of specific subsets of patients such as resistant organisms were excluded. RESULTS: 63 studies were identified that met the inclusion criteria. The majority of which (58) were reports of two-stage revision. Reinfection rated varied between 0% and 41% in two-stage studies, and 0% and 11% in single stage studies. No clinical trials were identified and the majority of studies were observational studies. CONCLUSIONS: Evidence for both one-stage and two-stage revision is largely of low quality. The evidence basis for two-stage revision is significantly larger, and further work into direct comparison between the two techniques should be undertaken as a priority

Obesity in total hip arthroplasty—does it really matter?: A meta-analysis

Discussion persists as to whether obesity negatively influences the outcome of hip arthroplasty. We performed a meta-analysis with the primary research question of whether obesity has a negative effect on short- and long-term outcome of total hip arthroplasty. We searched the literature and included studies comparing the outcome of hip arthroplasty in different weight groups. The methodology of the studies included was scored according to the Cochrane guidelines. We extracted and pooled the data. For continuous data, we calculated a weighted mean difference and for dichotomous variables we calculated a weighted odds ratio (OR). Heterogeneity was calculated using I(2) statistics. 15 studies were eligible for data extraction. In obese patients, dislocation of the hip (OR = 0.54, 95% CI: 0.38-0.75) (10 studies, n = 8,634), aseptic loosening (OR = 0.64, CI: 0.43-0.96) (6 studies, n = 5,137), infection (OR = 0.3, CI: 0.19-0.49) (10 studies, n = 7,500), and venous thromboembolism (OR = 0.56, CI: 0.32-0.98) (7 studies, n = 3,716) occurred more often. Concerning septic loosening and intraoperative fractures, no statistically significant differences were found, possibly due to low power. Subjective outcome measurements did not allow pooling because of high heterogeneity (I(2) = 68%). Obesity appears to have a negative influence on the outcome of total hip replacemen

High-intensity mechanical therapy for loss of knee extension for worker's compensation and non-compensation patients

<p>Abstract</p> <p>Background</p> <p>Knee flexion contractures have been associated with increased pain and a reduced ability to perform activities of daily living. Contractures can be treated either surgically or conservatively, but these treatment options may not be as successful with worker's compensation patients. The purposes of retrospective review were to 1) determine the efficacy of using adjunctive high-intensity stretch (HIS) mechanical therapy to treat flexion contractures, and 2) compare the results between groups of worker's compensation and non-compensation patients.</p> <p>Methods</p> <p>Fifty-six patients (19 women, 37 men, age = 51.5 ± 17.0 years) with flexion contractures were treated with HIS mechanical therapy as an adjunct to outpatient physical therapy. Mechanical therapy was only prescribed for those patients whose motion had reached a plateau when treated with physical therapy alone. Patients were asked to perform six, 10-minute bouts of end-range stretching per day with the ERMI Knee Extensionater^(r)(ERMI, Inc., Atlanta, GA). Passive knee extension was recorded during the postoperative visit that mechanical therapy was prescribed, 3 months after beginning mechanical therapy, and at the most recent follow-up. We used a mixed-model 2 × 3 ANOVA (group × time) to evaluate the change in passive knee extension between groups over time.</p> <p>Results</p> <p>Regardless of group, the use of adjunctive HIS mechanical therapy resulted in passive knee extension deficits that significantly improved from 10.5° ± 5.2° at the initial visit to 2.6° ± 3.5° at the 3 month visit (p < 0.001). The degree of extension was maintained at the most recent follow-up (2.0° ± 2.9°), which was significantly greater than the initial visit (p < 0.001), but did not differ from the 3 month visit (p = 0.23). The gains in knee extension did not differ between worker's compensation and non-compensation patients (p = 0.56).</p> <p>Conclusions</p> <p>We conclude that the adjunctive use of HIS mechanical therapy is an effective treatment option for patients with knee flexion contractures, regardless of whether the patient is being treated as part of a worker's compensation claim or not.</p

The comorbidity and co-medication profile of patients with progressive supranuclear palsy

BackgroundProgressive supranuclear palsy (PSP) is usually diagnosed in elderly. Currently, little is known about comorbidities and the co-medication in these patients.ObjectivesTo explore the pattern of comorbidities and co-medication in PSP patients according to the known different phenotypes and in comparison with patients without neurodegenerative disease.MethodsCross-sectional data of PSP and patients without neurodegenerative diseases (non-ND) were collected from three German multicenter observational studies (DescribePSP, ProPSP and DANCER). The prevalence of comorbidities according to WHO ICD-10 classification and the prevalence of drugs administered according to WHO ATC system were analyzed. Potential drug-drug interactions were evaluated using AiDKlinik (R).ResultsIn total, 335 PSP and 275 non-ND patients were included in this analysis. The prevalence of diseases of the circulatory and the nervous system was higher in PSP at first level of ICD-10. Dorsopathies, diabetes mellitus, other nutritional deficiencies and polyneuropathies were more frequent in PSP at second level of ICD-10. In particular, the summed prevalence of cardiovascular and cerebrovascular diseases was higher in PSP patients. More drugs were administered in the PSP group leading to a greater percentage of patients with polypharmacy. Accordingly, the prevalence of potential drug-drug interactions was higher in PSP patients, especially severe and moderate interactions.ConclusionsPSP patients possess a characteristic profile of comorbidities, particularly diabetes and cardiovascular diseases. The eminent burden of comorbidities and resulting polypharmacy should be carefully considered when treating PSP patients
