Developing and Validating a Conceptual Model of Recurring Problems in Teaching Clinic w

Recurrent problems in medical teaching clinic are common and difficult to address because of complex interpersonal dynamics. To minimize this difficulty, we developed a conceptual model that simplifies problems and identifies the root cause of tension between groups in clinic. We used recursive analysis and modeling of the data from a larger multi-site, multi-method study of problems in teaching clinic. The first dataset from this study consisted of problem lists generated and prioritized by knowledgeable insiders from each site. The second dataset was a cultural consensus analysis independently performed at each site. The final model was checked for face validity and construct validity (using model predictions versus prior data and convergent/discriminant analysis). The study was performed in five Veterans Affairs teaching clinics in the U.S. Our final model, the Perception of Care Map, is a pentagram with five critical perspectives of the clinic visit. These five perspectives are structured care, educational care, relationship-based care, algorithmic care and efficient care. Each group emphasizes one or more of these perspectives, and group locations on the conceptual map explain the observed tensions between groups. Validity of the model is high. The Perception of Care Map may be a useful adjunct for understanding and addressing recurrent problems in teaching clinic.
Quantitation of group A beta-hemolytic streptococci in throat culture.

In Kellogg's review (7) of throat culture procedures for the recovery of group A beta-hemolytic streptococci (GABHS), he rather summarily dispenses with quantitation of GABHS on the culture plates as providing any indication as to the presence or absence of true streptococcal infection. He cites two studies other than his own review article (8) as evidence for this statement. In the first, by Gerber et al. (4), there was no significant correlation between the degree of positivity of throat cultures and changes in antibody titers. In the second, by Kaplan et al. (6), although the correlation was not significant, there was a trend toward the association of an initial culture of2+ or greater (10 to 50 CFU ofGABHS) and serologic evidence of infection. Also, in a later study (5), Kaplan et al. found that there was a definite trend for individuals with strongly positive cultures to demonstrate an antibody rise. Similarly, in 127 streptococcal infections, Miller et al. (10) found 45% of "grade 3" cultures to be associated with at least a two-tube increase in anti-streptolysin 0, as opposed to only 19 and 6%, respectively, for "grade 2" and "grade 1" plates. They interpreted this as showing a "clear-cut relationship between the number of colonies and the frequency with which a significant increase in antistreptolysin-O was observed. " Whereas the above-mentioned studies lead to differing conclusions on the basis of antibody data, those which correlate clinical findings with throat culture results are very much in accord. In a private pediatric practice, Stillerman and Bernstein (11) compared positive cultures of 98 symptomatic and 96 asymptomatic cases and found that strongly positive cultures were much more likely to occur in the former group. In culturing 1,054 children with sore throats and 462 who were asymptomatic, Bell and Smith (1) found that 71% of the 350 positive cultures in the former group showed a heavy growth of GABHS as opposed to only 10% of the 80 positive isolates in the latter one. The findings of Margileth and Mella (9) were similar when they compared children with pharyngitis and their asymptomatic siblings. Wannamaker (12) and Breese et al. (3) in review articles and a panel of experts assembled by the chief editors of the Pediatric Infectious Disease Journal (2) all attest to the clinical importance of the degree of positivity of throat cultures for GABHS. The vast majority of studies which correlate patient symptomatology with throat culture quantitation support the belief that quantitation is at least of some importance in differentiating the streptococcal carrier state from true infection. To ignore these studies may be misleading, especially to those who are primarily or exclusively in the laboratory and do not have the opportunity of frequently correlating clinical and laboratory results.
Stress-Strain Relation of Confined Concrete under Dynamic Loading

A dynamic compression test was carried out on 126 cylinder specimens, which has 75 mm in diameter and 150 mm in height with or without confining spirals, in order to study strain rate effects on the stress-strain relation of confined concrete. Test variables were strain rate (static to 0.1/s ), original compressive concrete strength (30 MP a to 54MPa), amount of confining spiral (unconfined to 2.0% in volume ratio), and its yield strength (300 MPa and 850 MP a). It was found that the unconfined concrete had a strong strain rate sensitivity with respect to the peak stress and peak strain but the sensitivity decreased as the confining transverse stress increased. The enhanced peak stress increased linearly with the confining transverse stress when specimens had a same strain rate.
Malaria Parasitaemia among Primary School Children In Oko Community, Orumba North Local Government Area, Anambra State, Nigeria.

A prevalence study of malaria among primary school children in Oko community, Orumba North LGA, Anambra State, Southeastern Nigeria was carried out in 2011. Three schools, Gaius Benton, Holy Trinity and College Primary schools were investigated. A total of 216 pupils made up of equal number of boys and girls, 108 (50.0%) each, participated in the study. These were aged between 6 and 13 years. Microscopic examination of blood films was used to detect malaria parasites in their blood samples. Interview and physical observation were used to obtain biological data of the pupils as well as some predisposing environmental factors. Of the 216 pupils examined, 54 (25.0%) tested positive for malaria. More males, 38 (35.0%), than females, 16 (15.0%), tested positive for malaria. The difference was statistically significant (ᵪ2
An Air Traffic Management Data Traffic Pattern for Aeronautical Communication System Evaluations

Modern air traffic management relies on a communication infrastructure increasingly suffering from the VHF band's growing saturation in high density areas. Air traffic management communication shall therefore transition from analog VHF voice communication to more spectrum efficient digital data communication. These proposed digital technologies have to be evaluated carefully against the expected data traffic to ascertain that they offer the required capacity and performance. This paper describes the characteristics of air traffic management data and a method to generate a data traffic pattern suitable as input for the performance evaluation of digital aeronautical data communication systems. The data traffic pattern is derived from large scale computer simulations. Based on the simulation results, the paper provides guidance on how to model a data traffic pattern that is directly usable for practitioners wishing to evaluate the performance of aeronautical data communication systems.
Analytic solutions for acoustic scattering by blade rows with complex boundaries : porosity , compliance and impedance

The acoustic scattering by an infinite cascade of flat plates is analysed for a range of boundary conditions including porosity, compliance and impedance. By employing the Wiener-Hopf method, analytic expressions are derived for the pressure field that are uniformly valid throughout the entire domain. This enables exact solutions for the unsteady lift, sound power output and other acoustic quantities. The Wiener-Hopf analysis shows that complex boundaries have a significant effect on the modal structure of the cascade’s inter-blade region, whilst the modes in the far-field regions are unchanged. The results demonstrate the considerable impact of small modifications to the boundary conditions and highlight the importance of the accurate modelling of aeroelastic effects when predicting sound transmission and generation in turbomachinery.
The changing face of Ghanaian towns Kwasi

The paper argues that the face of Ghanaian towns has changed since the initial contact with the colonialists. Investments in infrastructure, urbanisation and enhanced economic activities have combined to change the face of Ghanaian towns. These changes in turn have affected the quality of urban life and the disparity in development between the north and the south as well as in various towns with marked spatial segregation of residential areas. Considering that the current face of several Ghanaian towns is characterised by overcrowding, cluttering of houses, insanitary conditions and poor environmental conditions; it is argued that the face of Ghanaian towns should increasingly reflect orderly development, adequate environmental sanitation, tolerable densities and effective local planning to create a more livable and sustainable environment.
Development of integrated disease management module for early blight of tomato in Jammu

Evaluation of chemical fungicides and plant extracts against Alternaria solani causing early blight of tomato revealed that Tebuconazole (25 EC) was the most effective fungicide followed by Difenconazole (25 EC). Amongst plant extracts, maximum mycelial inhibition was exhibited by Datura stramonium (20%) followed by Lantana camara (20%) and Azadirachta indica (20%). Amongst the bio agents tested using dual culture technique, Trichoderma harzianum showed maximum growth inhibition of the pathogen and appeared to be the most effective. To develop Integrated Disease Management module for early blight of tomato fungicides, plant extracts and bio agents were integrated in different treatments and applied in field with varying spray schedules consecutively for two seasons. It was observed that treatment comprising of Mancozeb (0.25%), Datura (50%) and T. harzianum s.t (1x107 spores/ml) reduced disease intensity up to 84.00% followed by treatment comprising of Mancozeb (0.25%) and T. harzianum s.t (1x107spores/ml) which reduced disease intensity to 82.33%.
Assessment of Nuclear Abnormalities in Erythrocytes of Balkan Pond Turtle Mauremys rivulata ( Valenciennes , 1833 ) ( Testudines : Geoemydidae ) from the Biga Stream , Çanakkale , Turkey

Reptilian species are potentially efficient bioindicators of pollution and habitat destruction. Turtles may be especially useful for monitoring the chemical contamination of their habitats. The aim of this study was to assess the genotoxic effect of environmental pollutants on Balkan pond turtle Mauremys rivulata (Valenciennes, 1833) from the Biga Streamр Canakkale, Turkey. Healthy mature animals were collected using the hand-capture method from four stations: estuary zone, city centre, buffer zone and industrial zone of the stream. Blood samples of live specimens were obtained in within one day of their capture. The peripheral blood smears for each specimen were prepared, fixed with methanol for 15 min and dyed with Giemsa stain. Micronuclei and other nuclear abnormalities such as blebbed, kidney-shaped, lobed and notched nuclei were identified. Comparing the nuclear abnormalities in the samples, it was determined that their frequency was highest in the samples collected from the station in the city centre (9.16±0.02). The results indicated that the levels of genotoxic pollutants in different regions of the Biga Stream lead to DNA damage in Mauremys rivulata.
INTRODUCING THE ANTHROPOLOGICAL THEORY OF THE DIDACTIC : AN ATTEMPT AT A PRINCIPLED APPROACH

Dear colleagues, ladies and gentlemen, my first words will be to thank the distinguished Japanese colleagues who have taken it upon themselves to invite me to deliver a lecture today here in Osaka. I also want to thank you all for being here today. And I wish to apologize for not being able to deliver my presentation in your mother tongue. By the same token let me apologize in advance to our wonderful translators for the puzzlement the involuntary intricacies of my talk may occasion. My aim in this lecture will be to paint an overall picture of the present state of the so-called anthropological theory of the didactic, or ATD for short. In trying to do so, I shall focus mainly on those points on which ATD departs most from the more widespread, ingrained approaches to education in general and to mathematics teaching in particular. Before I start on this short, casual journey, two or three remarks are in order. Firstly, although ATD has emerged as a theory of mathematics education, its construction over the last four decades has been aimed at providing us with adequate means of explaining and understanding the teaching and learning of any kind of knowledge, considered generally and specifically, be it mathematics, English, biology, history, or what have you. My second remark will be about something a little unsatisfying: in many cases—not all! —, I shall have to skip details and examples in order to highlight what I believe to be the essential aspects of the ATD approach. One more point before I really start lecturing. Every time I prepare (for) a lecture in English, which is neither my mother tongue nor my usual working language, as you can surmise from these introductory remarks, I have a quick look at a number of papers purporting to advise the unpretentious lecturer about the risks of the trade. Referring to the always lurking risk of cultural misunderstanding, one of them (“Presentation
Chapter 6 Resistant Gram-Negative Urinary Tract Bacterial Infections

Urinary tract infection (UTI) is one of the most common infections in both the community as well in hospital settings. It is mostly caused by Gram-negative bacteria (GNBs). Over the past two decades, GNBs have developed complex mechanisms of resistance against most of the potent antibiotics. This has been a global challenge which has been identified by the World Health Organization as “one of the greatest threats to human health. ” This crisis is mostly attributed to the overuse and misuse of these medications, as well as lack of new drug antimicrobials by the pharmaceutical industry. This resulted in prolonged hospital stay, marked increase in the cost as well as increase in morbidity and mortality. Furthermore, it increases the risks and complications of urological procedures. In this chapter, we review the management of the most common and challenging group of resistant Gram-negative organisms, the extended-spectrum β-lactamases producing organisms (ESBL) and the carbapenem-resistant organisms (CRE/CRP). The latter group includes carbapenem-resistant Enterobacteriaceae (CRE), as well as Pseudomonas aeruginosa carbapenemases (CRP). When treating these infections, clinicians have few effective antimicrobials options. A critical step in managing these organisms is the early recognition and appropriate empiric therapy. Both showed morbidity and mortality benefits.
Exploring the Dynamic Effects of Equity-Based Capital Inflows in BRINCS countries

This study investigates whether equity-based capital inflows have influences on short-run macroeconomic variables. Using a structural VAR model, the study estimates the response of output gap, inflation, exchange rate, and interest rate and foreign exchange reserves to an exogenous shock to equity-based capital inflows. Its findings reveal that an exogenous increase in equity-based capital inflows has effect on inflation and interest rate but no influence on output gap, exchange rate etc. Thus, the short-run macroeconomic effects of exogenous capital inflows are partially attributed to changes in equity-based capital inflows.
The Impact of Early Adoption of IFRS on the Quality of Accounting Information

After the various financial scandals, the debate concerning accounting information has been renewed in earnest. Consequently, we have decided to study the quality of accounting information. Indeed the aim of this article, which spans from the period of 2002 to 2006, is to study the impact of early adoption of IFRS (International Financial Reporting Standards) on the quality of accounting information. After reviewing the literature, we chose to study the following aspects:earnings managment and timely loss recognition. This study deals with as ample of the CAC (Cotation Assistee en Continu: Scoring Assisted Continuous) 40 companies. Panel number one is made up of companies that foresaw the adoption of IFRS. Panel number two consist of companies that waited for the legal date for the adoption of IFRS. After empirical tests, we noticed that for panel number one, the quality of accounting information has improved; while in panel number two, we noticed an increase in earnings managment. In conclusion, not foreseeing the adoption of IFRS hampers the companies and increases earning management.
French Specific Surveillance System for Drug Abuse

ABSTRACT It is important to assess drug abuse liability in real life by post-marketing surveillance system. In France, to obtain information on drug abuse liability, the Centers for Evaluation and Information on Pharmacodependence (CEIP) network was created in 1990 with the following aims: detection, prevention, evaluation, and information on drug abuse liability. Its specific work is based on a global, scientific assessment involving preclinical data, clinical studies, and post-marketing surveillance. This network has developed several pharmaco-epidemiological approaches to improve knowledge of drug use in real-life. The aim of this article was to describe a French post-marketing surveillance called OPPIDUM (Observation des Produits Psychotropes Illicites ou Détournés de leur Utilisation Médicamenteuse, Observation of Illegal Drugs and Misuse of Psychotropic Medications). OPPIDUM is an annual cross-sectional survey that collects anonymous information on abuse and dependence observed in patients recruited by specialized care centers dedicated to drug dependence. For each patient included sociodemographic data and psychoactive substance consumptions during the previous week were collected. From 1990 to 2010, a total of 50,734 patients were included with descriptions of 102,631 psychoactive substances. This OPPIDUM data has outlined emergent behaviors, such as use of high dosage buprenorphine by intravenous administration. It has contributed to characterize patients under opiate maintenance treatments and to assess abuse liability of emergent drugs as clonazepam. This pharmacoepidemiologic tool has also detected the decrease of flunitrazepam abuse following implementation of regulatory measures. OPPIDUM’s experience clearly demonstrates that collection of valid and useful data on drug abuse is possible. This post-marketing surveillance system offers important and useful information for physicians and health authorities.
Diagnostic potential of saliva as a biomarker in early childhood caries: A review

Early Childhood Caries (ECC) is a severe and early form of the carious disease that can compromise child’s oral and systemic health. Despite significant efforts to integrate children’s oral health into primary care, identification of children at risk for ECC before the onset of cavitation remains challenging. As teeth are bathed in saliva constantly, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of oral diseases including dental caries. Thus, it can be a promising tool in early identification and thereby preventing the further progression of caries in children. Hence, the aim of this review is to throw light on the current knowledge and utilisation of salivary biomarkers in terms of its predictive potential for ECC. A literature search was done using electronic databases PubMed, Google Scholar, and Cochrane Database for articles in English. Several keywords were used: Early childhood caries, salivary biomarkers, saliva, child. Some of the promising biomarkers include the microbiological species, electrolytes in saliva, antibodies, inflammatory mediators, glucosyltransferase and physical characteristics of saliva. Utilisation of these biomarkers in clinical practice might help the clinicians in improving the oral health status of the child.

Title A Complete Assessment of the Emissions Performance of Ethanol Blends and Iso-Butanol Blends from a Fleet of Nine PFI and GDI Vehicles Permalink

Biofuels, such as ethanol and butanol, have been the subject of significant political and scientific attention, owing to concerns about climate change, global energy security, and the decline of world oil resources that is aggravated by the continuous increase in the demand for fossil fuels. This study evaluated the potential emissions impacts of different alcohol blends on a fleet of modern gasoline vehicles. Testing was conducted on a fleet of nine vehicles with different combinations of ten fuel blends over the Federal Test Procedure and Unified Cycle. The vehicles ranged in model year from 2007-2014 and included four vehicles with port fuel injection (PFI) fueling and five vehicles with direct injection (DI) fueling. The ten fuel blends included ethanol blends at concentrations of 10%, 15%, 20%, 51%, and 83% by volume and iso-butanol blends at concentrations of 16%, 24%, 32%, and 55% by volume, and an alcohol mixture giving 10% ethanol and 8% iso-butanol in the final blend. The results showed some clear trends with increasing levels of alcohol in the blends for some pollutants, but not for others. There was a trend for lower CO, CO2, PM mass, and particle number, and lower fuel economy with higher alcohol content fuels. For other pollutants, such as THC, NMHC, CH4, and NOx, there were not strong fuel trends, while some carbonyl species showed some trends towards higher emissions for higher alcohol blends. The emissions profiles for the different vehicles also showed differences, with the wall-guided DI vehicles showing higher PM mass, and particle number compared to the PFI vehicles.
