Improving Reading Comprehension Using Contextual Teaching and Learning (CTL)
Authors: Aprizani Yudha
Published: March 2017

This study aimed to find out whether teaching-learning reading comprehension using Contextual Teaching and Learning (CTL) would get better results than using Direct Instruction approach. The research used a quantitative method. The population of the research was students from the Islamic University of Kalimantan Muhammad Arsyad Al-Banjari. The researcher used cluster random sampling to select two sample groups, the control group and the experimental group. The control group with 25 students was the class that continued to use the Direct Instruction approach. The experimental group, with 20 students, was the class tested using the CTL approach. The test was a written test with five multiple choice questions plus an essay test. The test was used to obtain the data. The students’ scores were the data for the study of reading comprehension comparing CTL and Direct Instruction. Based on the results of the study, the researcher found that CTL was more effective than Direct Instruction because the null hypothesis was rejected and the alternative hypothesis was accepted so that CTL was found to be better for teaching reading skills. CTL encourages materials that are related to the students’ surrounding so that it helps them use English related to their daily activities.

Published: March 2017

Study Design

Retrospective cohort.

Background

Star Excursion Balance Test (SEBT) performance differs by sport in healthy collegiate athletes, and lower extremity injury rates also vary by sport, sex, and athletic exposure. The relationship between SEBT performance and injury risk has not been evaluated with consideration of these additional variables, which may be necessary to fully describe the relationship between SEBT performance and injury risk.

Objectives

To assess the association between preseason SEBT performance and noncontact injury occurrence to the knee or ankle in Division I collegiate athletes when controlling for sport, sex, and athletic exposure.

Methods

Star Excursion Balance Test performance, starting status, and injury status were reviewed retrospectively in National Collegiate Athletic Association Division I collegiate athletes from a single institution. A total of 147 athletes were healthy at the time of preseason SEBT testing and either remained healthy (n = 118) or sustained a noncontact injury to the knee or ankle (n = 29) during their sport's subsequent competitive season. Side-to-side asymmetries were calculated in each direction as the absolute difference in reach distance between limbs. Star Excursion Balance Test reach distances and asymmetries were compared between groups using multivariable regression, controlling for sport, sex, and athletic exposure (starter, nonstarter). Receiver operating characteristic curves were used to determine optimal sensitivity and specificity for significant models.

Results

When controlling for sport, sex, and athletic exposure, SEBT side-to-side asymmetry in the anterior direction, expressed as an absolute or normalized to limb length, discriminated between injured and noninjured athletes (area under the curve greater than 0.82).

Conclusion

Assessing side-to-side reach asymmetry in the anterior direction of the SEBT may assist in identifying collegiate athletes who are at risk for sustaining noncontact injuries to the knee or ankle.

Background and Aims: Coronary intervention through radial artery is a preferred over femoral route. Different vasodilators are used to prevent radial artery spasm. Till date there is no study to compare the effects of various vasodilator regimes during radial coronary angiogram in Nepal. We aim to compare the efficacy of different vasodilator in our patients.Methods and Result: This is a single centre, prospective randomized trial between Verapamil, Nitroglycerine (GTN) and cocktail (Verapamil with GTN). All the patient undergoing coronary angiogram via radial approach, without the contraindication were randomized by a computer generated randomization protocol. Patient undergoing coronary procedures via the radial artery were divided into three groups. Patients in group A received intra-arterial cocktail (2.5 mg of Verapamil plus 100 mcg Nitroglycerine in 10 ml of normal saline), patients in group B received Verapamil (5mg) and patient in group C received Nitroglycerine (200mcg). Heparin of 3000U was given intravenously in all three groips. Altogether 207 patients underwent transradial coronary angiogram, 203 were randomized after exclusion. Over all Radial artery spasm was reported in 28 patients (13.79%). There was no statistically significant difference in spasm between the three regimens however when grading, there was significant higher grade of spasm in Verapamil group (13.23%, P value < 0.05). When comparing Verapamil and GTN separately there was significant higher spasm (21% vs 7%, P value < 0.05) with higher grades of spasm in verapamil group.Journal of Advances in Internal Medicine 2016;05(01):11-14
Correlation of visual inspection with cytological and histopathological findings in cervical neoplasia
Authors: Sherpa P , Pant AD
Published: March 2017

Background: Cervical cancer is one of the commonest malignancies and a leading cause of morbidity and mortality among women. The aim of this study was to evaluate the diagnostic value of Papanicolaou (PAP) smear and visual inspection with acetic acid as methods of cervical cancer screening.Materials and Methods: This was a observational cross-sectional study conducted from the period of 2068.11.01 to 2069.11.01. The study population consisted of women with histologically confirmed cervical intraepithelial neoplasia or invasive carcinoma who had undergone prior PAP smear.Results: During the study period 160 patients underwent both PAP smear and cervical biopsy. Of these patients, 49 had a histological diagnosis of cervical intraepithelial neoplasia or invasive carcinoma. The histopathological and cytological diagnoses were compared. Visual inspection with acetic acid status was available for 31 of the 49 cases. The sensitivity of PAP smear was 61%, specificity 97%, positive predictive value 91%, negative predictive value 85% and diagnostic accuracy 86% for detection of cervical neoplasia. Visual inspection with acetic acid had a sensitivity of 74%, specificity 48%, Positive predictive value 64%, Negative predictive value 60% and diagnostic accuracy of 63%. Combining the two procedures increased sensitivity by 26%, Negative predictive value by 11%  and diagnostic accuracy by 2 per cent.Conclusion: PAP smear has a higher specificity, Positive predictive value, Negative predictive value and diagnostic accuracy but lower sensitivity than visual inspection with acetic acid. Visual inspection with acetic acid by itself is not an effective screening method. A combination of PAP smear and visual inspection with acetic acidcan ensure adequate screening of cervical neoplasia.

Published: March 2017

Background: Breast carcinoma is the most frequent malignant tumor in women accounting for approximately 15% of female cancer deaths. It is the second most common malignancy among women in Nepal. Our objectives were to study the extent and spread of different histological types breast carcinoma in the eastern region of Nepal, to grade and stage the tumors, score the prognosis.Materials and Methods: A cross-sectional descriptive study of mastectomy specimens with axillary lymph node sampling was done for a period of two years. Diagnosis was done using WHO classification. Modified Bloom Richardson score and TNM system was used to grade and stage the tumors. Nottingham Prognostic index was applied to score the prognosis.Results: Out of 31 total cases, the most common histologic type was Invasive Carcinoma of No Special Type (67.74%). The largest tumor size was of 12cm which had poor NPI score. Most tumors were of grade II and T2. Out of 30 cases with lymph nodes, 13 were negative for metastasis pN0, 10 were pN1 and 7 were pN2. Extranodal spread was observed in 6 out of 17 cases with lymph node metastasis and was associated with higher grades and poor prognosis.Conclusion: Higher grade tumors, lymph node metastasis and extranodal extension are associated with higher Nottingham Prognostic Index score.

Published: March 2017

Despite a significant decrease over the last 50 years, the production of oats (Avena sativa L.) presents both environmental and health benefits. When incorporated in crop rotations, oat has the potential to improve soil health and to break pest cycles in corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations. In addition, the presence of a soluble dietary fiber (β‐glucan) in oat grain can help prevent cholesterol, coronary heart diseases, and type 2 diabetes. The development of new oat cultivars with superior productivity and high test weight is required to improve the attractiveness of the crop to producers and to maintain or increase oat production in the United States. ‘Hayden’ (Reg. No. CV‐383, PI 676028) is a spring oat cultivar developed at South Dakota State University and released by the South Dakota Agricultural Experiment Station in 2014. The pedigree of Hayden is ‘Buckskin’//ND011054/SD020835. Hayden was developed using a modified bulk and single seed descent selection method. Hayden is a white hulled cultivar with mid‐to‐late maturity. Hayden was evaluated in the South Dakota Crop Performance Testing Oat Variety Trial from 2013 to 2015 and in the Uniform Mid‐Season Oat Performance Nursery in 2013 and 2014 under the experimental number SD111972. Hayden was released because of its excellent yield potential, good yield stability, and high test weight. It is resistant to smut and moderately tolerant to Barley yellow dwarf virus. Hayden also demonstrates good overall milling and nutritional quality.
Problems and questions in derived adjectives
Authors: Fábregas Antonio , Marín Rafael
Published: March 2017

This article overviews the main questions that emerge from cross-linguistic analysis of morphologically complex adjectives. It is discussed that the problems arise from the fact that it is difficult to identify any positive properties of adjectives capable of singling them out with respect to other categories. Thus, what has been classified as a derived adjective frequently is a version of the base category that lacks some of the definitional properties of that category. This article examines the questions related to deverbal adjectives, participles and denominal adjectives.
Fuzzy Random Walkers with Second Order Bounds: An Asymmetric Analysis
Authors: Drakopoulos Georgios , Kanavos Andreas , Tsakalidis Konstantinos
Published: March 2017

Edge-fuzzy graphs constitute an essential modeling paradigm across a broad spectrum of domains ranging from artificial intelligence to computational neuroscience and social network analysis. Under this model, fundamental graph properties such as edge length and graph diameter become stochastic and as such they are consequently expressed in probabilistic terms. Thus, algorithms for fuzzy graph analysis must rely on non-deterministic design principles. One such principle is Random Walker, which is based on a virtual entity and selects either edges or, like in this case, vertices of a fuzzy graph to visit. This allows the estimation of global graph properties through a long sequence of local decisions, making it a viable strategy candidate for graph processing software relying on native graph databases such as Neo4j. As a concrete example, Chebyshev Walktrap, a heuristic fuzzy community discovery algorithm relying on second order statistics and on the teleportation of the Random Walker, is proposed and its performance, expressed in terms of community coherence and number of vertex visits, is compared to the previously proposed algorithms of Markov Walktrap, Fuzzy Walktrap, and Fuzzy Newman–Girvan. In order to facilitate this comparison, a metric based on the asymmetric metrics of Tversky index and Kullback–Leibler divergence is used.
Epistemology and Education
Authors: Stables Andrew
Published: March 2017

While philosophy of education is often considered an applied discipline, it has made contributions across the philosophical spectrum. For example, there has been a significant body of work on aesthetics and education. There have been occasional incursions into debates about ontology and even, albeit rarely, metaphysics. However, the majority of work has always been concerned with epistemology (questions of knowing) and ethics (questions of right action). Traditionally, much of this work, particularly in epistemology, has had a highly individualistic tendency. The assumption of the knowing mind as key characteristic of the rational autonomous agent is at the heart of the liberal educational tradition and takes root in Descartes’ cogito: even if I doubt who I am, there is an ‘I’ that doubts, and this ‘I’ is the fundamental characteristic of the autonomous rational agent, the fully human being.
Combustion Characteristics and Slagging during Co-Combustion of Rice Husk and Sewage Sludge Blends
Authors: Rong Hao , Wang Teng , Zhou Min , Wang Hao , Hou Haobo , Xue Yongjie
Published: March 2017

In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout characteristics were also studied. The blends had rice husk percentages of 30, 50, 70 and 100%. The results indicate that there are four main stages of the material burning processes: dehydration, volatile oxidation, and decomposition/oxidation. The reactivity of the blends improved with increasing amounts of rice husk and the results suggest synergistic interactions between rice husk and sewage sludge during the co-combustion process. All co-combustion ashes showed a lower slagging potential owing to their high amorphous SiO2 content. On the basis of combustion properties and slagging characteristics of ash, the ratio of sewage sludge in the blends should not exceed 30%.
Simulated Summer Rainfall Variability Effects on Loblolly Pine (Pinus taeda) Seedling Physiology and Susceptibility to Root-Infecting Ophiostomatoid Fungi
Authors: Chieppa Jeff , Eckhardt Lori , Chappelka Arthur
Published: March 2017

Seedlings from four families of loblolly pine (Pinus taeda L.) were grown in capped open-top chambers and exposed to three different weekly moisture regimes for 13 weeks. Moisture regimes varied in intensity and frequency of simulated rainfall (irrigation) events; however, the total amounts were comparable. These simulated treatments were chosen to simulate expected changes in rainfall variability associated with climate change. Seedlings were inoculated with two root-infecting ophiostomatoid fungi associated with Southern Pine Decline. We found susceptibility of loblolly pine was not affected by water stress; however, one family that was most sensitive to inoculation was also most sensitive to changes in moisture availability. Many studies have examined the effects of drought (well-watered vs. dry conditions) on pine physiology and host-pathogen interactions but little is known about variability in moisture supply. This study aimed to elucidate the effects of variability in water availability, pathogen inoculation and their interaction on physiology of loblolly pine seedlings.
“I Do, I Don’t”: The Benefits and Perils of Legalizing Same-Sex Marriage in the United States—One Year Later
Authors: Wolff Kristina
Published: March 2017

In 1970, a gay male couple applied for and was given a marriage license in Minnesota. The license was eventually rescinded by court order. Forty-five years later, the U.S. Supreme Court ruled that Section 3 of the Defense of Marriage Act, limiting the federal definition of marriage to consist of one man and one woman, was unconstitutional. The result was the legalization of same-sex marriage in the United States. The purpose of this article is to discuss the importance of establishing the right for same-sex couples to legally marry. It outlines the benefits and costs to LGBT communities one year after the establishment of same-sex marriage in the U.S. This paper explores the limits of utilizing a rights-based approach when advocating social change. The recommendation is for LGBT individuals, communities and allies to shift tactics to adopt a capabilities approach to organizing and mobilizing people, groups, and organizations around issues of injustice. A capabilities framework addresses the complexities of individual and community needs while providing a foundation for coalition building and lasting positive social change.
Analysis of DNA Methylation Status in Bodily Fluids for Early Detection of Cancer
Authors: Yokoi Keigo , Yamashita Keishi , Watanabe Masahiko
Published: March 2017

Epigenetic alterations by promoter DNA hypermethylation and gene silencing in cancer have been reported over the past few decades. DNA hypermethylation has great potential to serve as a screening marker, a prognostic marker, and a therapeutic surveillance marker in cancer clinics. Some bodily fluids, such as stool or urine, were obtainable without any invasion to the body. Thus, such bodily fluids were suitable samples for high throughput cancer surveillance. Analyzing the methylation status of bodily fluids around the cancer tissue may, additionally, lead to the early detection of cancer, because several genes in cancer tissues are reported to be cancer-specifically hypermethylated. Recently, several studies that analyzed the methylation status of DNA in bodily fluids were conducted, and some of the results have potential for future development and further clinical use. In fact, a stool DNA test was approved by the U.S. Food and Drug Administration (FDA) for the screening of colorectal cancer. Another promising methylation marker has been identified in various bodily fluids for several cancers. We reviewed studies that analyzed DNA methylation in bodily fluids as a less-invasive cancer screening.
Zerumbone Alleviates Neuropathic Pain through the Involvement of l-Arginine-Nitric Oxide-cGMP-K+ ATP Channel Pathways in Chronic Constriction Injury in Mice Model
Authors: Zulazmi Nurul , Gopalsamy Banulata , Min Jasmine , Farouk Ahmad , Sulaiman Mohd , Bharatham B. , Perimal Enoch
Published: March 2017

The present study investigates the involvement of the l-arginine-Nitric Oxide-cGMP-K+ ATP pathways responsible for the action of anti-allodynic and antihyperalgesic activities of zerumbone in chronic constriction injury (CCI) induced neuropathic pain in mice. The role of l-arginine-NO-cGMP-K+ was assessed by the von Frey and the Randall-Selitto tests. Both allodynia and hyperalgesia assessments were carried out on the 14th day post CCI, 30 min after treatments were given for each respective pathway. Anti-allodynic and antihyperalgesic effects of zerumbone (10 mg/kg, i.p) were significantly reversed by the pre-treatment of l-arginine (10 mg/kg), 1H [1,2,4]Oxadiazole[4,3a]quinoxalin-1-one (ODQ), a soluble guanosyl cyclase blocker (2 mg/kg i.p.) and glibenclamide (ATP-sensitive potassium channel blocker) (10 mg/kg i.p.) (p < 0.05). Taken together, these results indicate that systemic administration of zerumbone produces significant anti-allodynic and antihyperalgesic activities in neuropathic pain in mice possibly due to involvement of the l-arginine-NO-cGMP-PKG-K+ ATP channel pathways in CCI model.

Published: March 2017

An actinomycete strain (H12-15) isolated from a sea sediment in a mangrove district was identified as Streptomyces antibioticus on the basis of 16S rDNA gene sequence analysis as well as the investigation of its morphological, physiological, and biochemical characteristics. Two novel benzamido nonacyclic dilactones, namely neoantimycins A (1) and B (2), together with the known antimycins A1ab (3a,b), A2a (4), and A9 (5), were isolated from the culture broth of this strain. Compounds 1 and 2 are the first natural modified ATNs with an unusual benzamide unit. The structures of these new compounds, including their absolute configuration, were established on the basis of HRMS, NMR spectroscopic data, and quantum chemical ECD calculations. Their cytotoxicities against human breast adenocarcinoma cell line MCF-7, the human glioblastoma cell line SF-268, and the human lung cancer cell line NCI-H460 were also tested. All compounds exhibited mild cytotoxic activity. However, Compounds 1 and 2 showed no activity against C. albicans at the test concentration of 1 mg/mL via paper disc diffusion, while the known antimycins showed obvious antifungal activity.
Attitudes of newly qualified doctors towards a career in general practice: a qualitative focus group study
Authors: Merrett Alexandra , Jones Daniel , Sein Kim , Green Trish , Macleod Una
Published: March 2017

Background

A key element of the NHS is universal access to a GP. Recently, UK general practice has been described as being in crisis, with training places unfilled and multiple practices reporting vacancies or facing closure. The recruitment of GPs continues to be a key focus for both the Royal College of General Practitioners (RCGP) and the government.

Aim

To understand the attitudes of newly qualified doctors towards a career in general practice, to appreciate potential reasons for the crisis in GP recruitment, and to recommend ways to improve recruitment.

Design and setting

A qualitative study comprising five focus groups with 74 Foundation Year 1 (FY1) doctors from one Yorkshire deanery.

Method

Audio recordings were transcribed verbatim and thematic analysis undertaken.

Results

Foundation Year 1 doctors’ thoughts towards a career in general practice were summarised in four themes: quality of life, job satisfaction, uncertainty surrounding the future of general practice, and the lack of respect for GPs among both doctors and the public. Participants felt that general practice could provide a good work–life balance, fair pay, and job stability. Job satisfaction, with the ability to provide care from the cradle to the grave, and to work within a community, was viewed positively. Uncertainties around future training, skill levels, pay, and workload, together with a perceived stigma experienced in medical schools and hospitals, were viewed as a deterrent to a career in general practice.

Conclusion

This study has gathered the opinions of doctors at a critical point in their careers, before they choose a future specialty. Findings highlight areas of concern and potential deterrents to a career in general practice, together with recommendations to address these issues.

Published: March 2017

Background

Little is known about the risk of progressing to hazardous alcohol use in abstinent or low-risk drinkers.

Aim

To develop and validate a simple brief risk algorithm for the onset of hazardous alcohol drinking (HAD) over 12 months for use in primary care.

Design and setting

Prospective cohort study in 32 health centres from six Spanish provinces, with evaluations at baseline, 6 months, and 12 months.

Method

Forty-one risk factors were measured and multilevel logistic regression and inverse probability weighting were used to build the risk algorithm. The outcome was new occurrence of HAD during the study, as measured by the AUDIT.

Results

From the lists of 174 GPs, 3954 adult abstinent or low-risk drinkers were recruited. The ‘predictAL-10’ risk algorithm included just nine variables (10 questions): province, sex, age, cigarette consumption, perception of financial strain, having ever received treatment for an alcohol problem, childhood sexual abuse, AUDIT-C, and interaction AUDIT-C*Age. The c-index was 0.886 (95% CI = 0.854 to 0.918). The optimal cutoff had a sensitivity of 0.83 and specificity of 0.80. Excluding childhood sexual abuse from the model (the ‘predictAL-9’), the c-index was 0.880 (95% CI = 0.847 to 0.913), sensitivity 0.79, and specificity 0.81. There was no statistically significant difference between the c-indexes of predictAL-10 and predictAL-9.

Conclusion

The predictAL-10/9 is a simple and internally valid risk algorithm to predict the onset of hazardous alcohol drinking over 12 months in primary care attendees; it is a brief tool that is potentially useful for primary prevention of hazardous alcohol drinking.
Evidence for Abnormal Hα Variability During Near-transit Observations of HD 189733 b
Authors: Cauley P. Wilson , Redfield Seth , Jensen Adam G.
Published: March 2017

Changes in levels of stellar activity can mimic absorption signatures in transmission spectra from circumplanetary material. Thus, it is critical to understand the frequency and magnitude of these changes in order to attribute any particular signal to the circumplanetary environment. We present short-cadence, high-resolution out-of-transit Hα spectra for the hot Jupiter host HD 189733 in order to establish the frequency and magnitude of intrinsic stellar variations in the Hα line core. We find that changes in the line core strength similar to those observed immediately pre- and post-transit in two independent data sets are uncommon. This suggests that the observed near-transit signatures are either due to absorption of circumplanetary material or they occur preferentially in time, very near planetary transits. In either case, the evidence for abnormal Hα variability is strengthened, though the short-cadence out-of-transit data do not argue for circumplanetary absorption versus stellar activity caused by a star–planet interaction. Further out-of-transit monitoring at higher signal-to-noise would be useful to more strictly constrain the frequency of the near-transit changes in the Hα line core.
Morphology Dependence of Stellar Age in Quenched Galaxies at Redshift ∼1.2:Massive Compact Galaxies Are Older than More Extended Ones

Published: March 2017

We report the detection of morphology-dependent stellar age in massive quenched galaxies (QGs) at z ∼ 1.2. The sense of the dependence is that compact QGs are 0.5–2 Gyr older than normal-sized ones. The evidence comes from three different age indicators—

D

n

4000

,

H

δ

, and fits to spectral synthesis models—applied to their stacked optical spectra. All age indicators consistently show that the stellar populations of compact QGs are older than those of their normal-sized counterparts. We detect weak [O ii] emission in a fraction of QGs, and the strength of the line, when present, is similar between the two samples; however, compact galaxies exhibit a significantly lower frequency of [O ii] emission than normal ones. Fractions of both samples are individually detected in 7 Ms Chandra X-ray images (luminosities ∼1040–1041 erg s−1). The 7 Ms stacks of nondetected galaxies show similarly low luminosities in the soft band only, consistent with a hot gas origin for the X-ray emission. While both [O ii] emitters and nonemitters are also X-ray sources among normal galaxies, no compact galaxy with [O ii] emission is an X-ray source, arguing against an active galactic nucleus (AGN) powering the line in compact galaxies. We interpret the [O ii] properties as further evidence that compact galaxies are older and further along in the process of quenching star formation and suppressing gas accretion. Finally, we argue that the older age of compact QGs is evidence of progenitor bias: compact QGs simply reflect the smaller sizes of galaxies at their earlier quenching epoch, with stellar density most likely having nothing directly to do with cessation of star formation.

, ULIRGs: log

], in the Great Observatories All-Sky LIRG Survey (GOALS), based on observations with the Herschel Space Observatory Photodetector Array Camera and Spectrometer (PACS) and the Spectral and Photometric Imaging Receiver (SPIRE) instruments. The image atlas displays each GOALS target in the three PACS bands (70, 100, and 160 μm) and the three SPIRE bands (250, 350, and 500 μm), optimized to reveal structures at both high and low surface brightness levels, with images scaled to simplify comparison of structures in the same physical areas of ∼100 × 100 kpc2. Flux densities of companion galaxies in merging systems are provided where possible, depending on their angular separation and the spatial resolution in each passband, along with integrated system fluxes (sum of components). This data set constitutes the imaging and photometric component of the GOALS Herschel OT1 observing program, and is complementary to atlases presented for the Hubble Space Telescope, Spitzer Space Telescope, and Chandra X-ray Observatory. Collectively, these data will enable a wide range of detailed studies of active galactic nucleus and starburst activity within the most luminous infrared galaxies in the local universe.

As a consequence of the Rydberg-valence interaction, irregularities in the vibrational structure of the above band systems are observed. Good agreement is found with the scarce high-resolution data that are available for oscillator strengths. The new band oscillator strengths reported here may be useful for a reliable interpretation of the spectra from atmospheres of the Earth, Titan, and Triton, where

En théologie trinitaire ou en christologie, on aborde fort peu la question de l’intégration, à l’Ascension, d’une humanité à la fois glorieuse et semblable à la nôtre au sein de la vie trinitaire. Or le fait est sans doute plus inouï encore qu’un Dieu qui se soit fait homme. On désire mettre en évidence l’efficience salvifique de l’Ascension, la mission actuelle du Verbe incarné, et l’incidence que la foi en l’exaltation du Verbe incarné a sur l’annonce, la mystique et l’eschatologie chrétiennes.

Dans les quatre pays décrits ci-après, le sport joue un rôle significatif dans la société ; il est utilisé comme un véhicule important pour atteindre des objectifs allant des politiques de la santé à la criminalité. Alors que la négligence de responsabilité s’est développée dans chaque système juridique, celle impliquée dans l’organisation, l’administration et la participation sportive est devenue un réel sujet et de responsabilité potentielle. Les conséquences sont importantes pour le champ du sport dans la société civile, les pratiques de coaching en elles-mêmes et le coach. Ce texte couvre les diverses approches de la responsabilité civile et les règlements essentiels pour les coachs dans trois juridictions qui, toutes, ont puisé leur source dans le système du droit coutumier anglais. Il présente aussi une quatrième approche non légale de la responsabilité potentielle du coach, pour des indemnisations d’accidents, à travers le cas de la Nouvelle-Zélande où aucun cadre juridique n’a été établi depuis que la loi de l’Accident Compensation de 1972 a été votée. Une considération majeure consiste à se demander dans quelle mesure l’histoire et la culture du système national légal a formé et induit les approches contemporaines de la responsabilité du coach. Angleterre et Pays de Galles : une négligence de responsabilité sans restriction Le délit de droit coutumier de négligence s’est développé à travers l’application de principes généraux depuis 1932 et les coachs n’ont jamais eu la chance d’avoir un statut privilégié pour atténuer leur responsabilité alors que l’intervention limitée de l’État s’est montrée inefficace. États-Unis : immunité étatique bénévole des procès La responsabilité de négligence des coachs ayant causé des blessures aux athlètes a été qualifiée par le concept de responsabilité souveraine dans le secteur public. Plus encore, le système fédéral a permis aux États d’intervenir directement pour protéger les coachs bénévoles à travers l’arrêt de Protection bénévole bien que ce soit de manière décousue. Afrique du Sud : la responsabilité est passée des éducateurs individuels au niveau de l’État L’arrêt pour l’école n° 84 de 1996 s 60. Les enseignants scolaires qui interviennent en tant que coach ne sont pas individuellement responsables pour les fautes commises pour négligence : la responsabilité reste du domaine de l’État. Nouvelle-Zélande : la responsabilité déplacée des coachs L’État fonctionnant, depuis 1974, sur l’absence de cadre compensatoire pour faute, fournit un chemin alternatif pour ceux qui sont blessés par les négligences du coach. Ce texte explore les similarités et les différences dans les systèmes juridiques, les cultures et les conséquences pour les coachs. Une question fondamentale est de savoir si les racines culturelles et l’histoire sont des obstacles insurmontables à changer.

The spectrum of injuries associated with femoral shaft fractures and those injuries' association with mortality have not been well delineated previously. Patients in the National Trauma Data Bank who presented with femoral shaft fractures from 2011 to 2012 were analyzed in 3 age groups (18–39, 40–64, and 65+ years). For each group, modified Charlson Comorbidity Index (CCI), mechanism of injury (MOI), injury severity score (ISS), and associated injuries were reported. Multivariate logistic regression was used to identify predictors of mortality. Among the 26,357 patients with femoral shaft fractures, modified CCIs gradually increased with increasing age category and ISS decreased. Motor vehicle accidents were the most common MOI in the younger 2 age groups, whereas falls were the most common MOI in the 65 years and older age group. The top 3 associated bony injuries for the study cohort as a whole were tibia/fibula (20.5%), ribs/sternum (19.1%), and non-shaft femur (18.9%, of which 5.8% of the total cohort were femoral neck) fractures. The top 3 associated internal organ injuries were lung (18.9%), intracranial (13.5%), and liver (6.2%), injuries. A multivariate mortality analysis showed that increasing age, increasing comorbidity burden, and associated injuries all had independent associations with mortality. The injuries most associated with mortality were thoracic organ injuries (adjusted odds ratio [AOR]=3.53), head injuries (AOR=2.93), abdominal organ injuries (AOR=2.78), and pelvic fractures (AOR=1.80). This study used a large, nationwide sample of trauma patients to profile injuries associated with femoral shaft fractures. Associations between injuries and mortality underscore the importance of these findings. [Orthopedics.2017; 40(3):e506–e512.]

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was assessed. The Medicare database was searched from 2005 to 2012 using
International Classification of Diseases, Ninth Revision,
procedure codes for primary THA and diagnosis codes for preoperative diagnoses of lumbosacral spondylosis, lumbar disk herniation, acquired spondylolisthesis, and degenerative disk disease. The control group consisted of all patients without a lumbar spine diagnosis who underwent THA. The risk ratios for prosthetic hip dislocation, revision THA, periprosthetic fracture, and infection were significantly higher for all 4 lumbar diseases at all time points relative to controls. The average complication risk ratios at 90 days were 1.59 for lumbosacral spondylosis, 1.62 for disk herniation, 1.65 for spondylolisthesis, and 1.53 for degenerative disk disease. The average complication risk ratios at 2 years were 1.66 for lumbosacral spondylosis, 1.73 for disk herniation, 1.65 for spondylolisthesis, and 1.59 for degenerative disk disease. Prosthetic hip dislocation was the most common complication at 2 years in all 4 spinal disease cohorts, with risk ratios ranging from 1.76 to 2.00. This study shows a significant increase in the risk of complications following THA in patients with lumbar spine disease. [

Published: March 2017

The aim of this study was to investigate clinical and radiographic outcomes in patients 50 years and younger vs patients older than 50 years undergoing total ankle replacement. Seventy consecutive patients who underwent primary total ankle replacement were included in this retrospective study. Patients were assessed clinically and radiographically. There was a statistically significant difference between the 2 groups for the American Orthopaedic Foot & Ankle Society score at final follow-up. The younger group had significantly greater improvement compared with the older group. Total ankle arthroplasty is an effective treatment for young, active patients with symptomatic end-stage ankle arthritis. [

Published: March 2017

Polyethylene glycol (PEG-200) and itaconic acid (IA) were used as raw materials to compound macromer through esterification reaction. A new type of specialized water-coke slurry dispersant was synthesized by copolymerization of microware, sodium methallyl sulfonate (SMAS) and maleic anhydride (MA). The experiment showed that the concentration of slurry could be reached to 63% with the dosage of 0.2%, and the apparent viscosity was 1140.3 mPa∙s. Through the analysis of the infrared, the dispersant was confirmed to have polyethylene glycol branched chain and hydrophilic functional groups such as carboxyl or sulfonic group. When the concentration of dispersant was 30 g/L, the surface tension of water could be decreased from 72.70 mN/m to 45.50 mN/m. Furthermore, when the solution pH value was 9, the Zeta potential of semi-coke powder surface could also be decreased from-13.38 mV to-25 mV with the addition of dispersant. Thus, this dispersant could increase electronegativity of semi-coke powder surface, enhance steric-hindrance effect and prevent the phenomenon of powder flocculation and gather. Meantime, it also could reinforce the semi-coke hydrophilic by reducing the surface tension of water effectively. And then, the high performance water-coke slurry could be obtained.

Fine microstructure of twinning Martensite/austenite (M/A) islands in a X100 high strength pipeline steel were analyzed by the scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM), and a uniaxial compressive experiment of micro-pillar for a twinning M/A island was conducted in present paper. The experimental results showed that M/A islands in X100 pipeline steels were consisted of retained austenite and nanoscale twins with sizes of less than ten nanometers. There were a few small blocks of nanoscale twins in an M/A island. Volume fraction of twinning M/A islands had an important effect on mechanical properties of X100 pipeline steels, with the increase of twinning M/A islands fraction, yield strength of X100 pipeline steel increased, and impact toughness of X100 pipeline steel decreased. The micro-pillar compression showed that the nanoscale twinning M/A island exhibited the higher deformation hardening during the compressive test, and its uniaxial compressive strength could up to 1.35GPa ultrahigh stress level.

Published: March 2017

Alternating current impedance has been used to study effects of hydration stages and molar ratio on the pore structure and hydration characters of basic magnesium sulfate cement. The alternating current impedance spectra of at early hydration almost appears as a straight line because none crystal hydration phases form. And it appears high frequency semicircle at late hydration stage because of decreasing of porosity and amount of 5Mg (OH)2 ·MgSO4·7H2O gradually form with ages. Besides, alternating current impedance spectra differences among basic magnesium sulfate, magnesium oxysulfate and magnesium oxychloride cement have been studied. These differences indicate that additives such as citric acid may change the structure and charge characteristics of MgO hydration layer which make tends to form more 5Mg (OH)2 ·MgSO4·7H2O phase in basic magnesium sulfate cement than that in magnesium oxysulfate cement. The higher pore solution resistance of BMS cement is the main factor of better steel-protection.
Advances in Rapid Identification and Susceptibility Testing of Bacteria in the Clinical Microbiology Laboratory: Implications for Patient Care and Antimicrobial Stewardship Programs
Authors: Maurer Florian P. , Christner Martin , Hentschke Moritz , Rohde Holger
Published: March 2017

Early availability of information on bacterial pathogens and their antimicrobial susceptibility is of key importance for the management of infectious diseases patients. Currently, using traditional approaches, it usually takes at least 48 hours for identification and susceptibility testing of bacterial pathogens. Therefore, the slowness of diagnostic procedures drives prolongation of empiric, potentially inappropriate, antibacterial therapies. Over the last couple of years, the improvement of available techniques (e.g. for susceptibility testing, DNA amplification assays), and introduction of novel technologies (e.g. MALDI-TOF) has fundamentally changed approaches towards pathogen identification and characterization. Importantly, these techniques offer increased diagnostic resolution while at the same time shorten the time-to-result, and are thus of obvious importance for antimicrobial stewardship. In this review, we will discuss recent advances in medical microbiology with special emphasis on the impact of novel techniques on antimicrobial stewardship programs.
