THE PHYSICAL EDUCATION TEACHER IN SELF AND PEER ASSESSMENT

Teacher personality patterns, shaped in the form of characteristics attributed to particular groups of teachers of the given subject, as if they were accepted in school practice. Such opinions are generally formulated by pupils. The present study is an attempt to analyse opinions on distinguishing characteristics of physical education teachers as they are perceived by teachers of other subjects, and to compare them with the PE teachers’ self-assessment. The study results show that, in the opinion of physical education teachers, the strongest features of their professional identity are their organisation skills and dynamics in action; they are also distinguished by their optimism, clothes style, manners, commitment to work, and being resourceful in life. They perceive these image attributes as of high quality. However, teachers of other subjects assess these features much lower. In their opinion, the strongest distinguishing feature of physical education teachers in the school is mainly their outfit; they are also identified by dynamics in action, optimism, lifestyle, involvement at work, and courage. This means that - either the physical education teachers have a very high opinion of their value, or their peers teaching other subjects underestimate the assessment. Undoubtedly, the self-perception factor and related mechanisms of self-promotion and depreciation play certain role in this case.
Impact of under-compensation and over-compensation of dead-time effect on small-signal stability of induction motor drive

Inverter dead-time is known to make open-loop induction motor drives oscillatory, while operating at light-loads in particular. While dead-time compensation schemes exist, precise compensation of the same is often challenging as it involves factors such as device and driver delays and switching transition times, which are difficult to be quantified accurately. Hence, the effect of dead-time could be under- or over-compensated. A theoretical and experimental study on the impact of such under-compensation and over-compensation on the stability of a 100-kW induction motor drive is presented here. Small-signal models are proposed for an open-loop drive, when it is under-compensated and over-compensated. Stability analysis of the above motor drive is reported, which predicts the fundamental frequency range of oscillatory behaviour for both these cases. Further, different types of oscillatory behaviour are observed for the two cases. The analyses are supported by simulation and experimental results.
Event-Related Potentials Elicited by the Explicit and Implicit Processing of Familiarity in Faces

Brain activity underlying explicit and implicit processing of face familiarity was assessed by Event-Related Potentials (ERPs) elicited by famous and unknown faces with happy or neutral expressions. A set of faces was presented in a familiarity judgment (explicit) task and another in an expression judgment (implicit familiarity) task. After recording, these tasks were repeated exchanging the stimuli, and post-recording behavioral data from the familiarity task were used for re-averaging EEG segments from the expression task. Both explicit and implicit processing of famous faces resulted in an enhanced N250. Explicit processing of famous faces was specifically associated with earlier N400 and P600, with increased activity within brain areas involved in identity processing around 250 and 450 ms. These findings suggest different brain dynamics for explicit and implicit face processing, and that implicit processing of the identity in the context of an expression task is mainly associated with the transient activation of face representations in memory.
Skin absorption of six performance amines used in metalworking fluids

Every year, 10 million workers are exposed to metalworking fluids (MWFs) that may be toxic. There are four types of MWFs: neat oils and three water‐based MWFs (soluble oil, semisynthetic and synthetic), which are diluted with water and whose composition varies according to the mineral oils ratio. MWFs also contain various additives. To determine the absorption of six amines used as corrosion inhibitors and biocides in MWFs, porcine skin flow‐through diffusion cell experiments were conducted with hydrophilic ethanolamines (mono‐, di‐ and triethanolamine, MEA, DEA and TEA respectively) and a mixture of lipophilic amines (dibutylethanolamine, dicyclohexylamine and diphenylamine). The six amines were dosed in four vehicles (water and three generic water‐based MWF formulations) and analyzed using a scintillation counter or gas chromatography/mass spectrometry. These 24 h studies showed that dermal absorption significantly (P < 0.05) increased from water for the six amines (e.g. 1.15 ± 0.29% dose; DEA in water) compared to other formulations (e.g. 0.13 ± 0.01% dose; DEA in semisynthetic MWF) and absorption was greatest for dibutylethanolamine in all the formulations. The soluble oil formulation tended to increase the dermal absorption of the hydrophilic amines. The permeability coefficient was significantly higher (P < 0.05) with TEA relative to the other hydrophilic amines (e.g. 4.22 × 10–4 ± 0.53 × 10–4 cm h–1 [TEA in synthetic MWF] vs. 1.23 × 10–4 ± 0.10 × 10–4 cm h–1 [MEA in synthetic MWF]), except for MEA in soluble oil formulation. Future research will confirm these findings in an in vivo pig model along with dermatotoxicity studies. These results should help MWF industries choose safer additives for their formulations to protect the health of metalworkers. Copyright © 2014 John Wiley & Sons, Ltd.
Texture Feature Analysis to Predict Metastatic and Necrotic Soft Tissue Sarcomas

Soft Tissue Sarcomas (STS) are malignant tumors which emanate from soft tissues of the body. They are challenging for physicians because of the infrequency of their occurrence and non-predictable outcomes. In this paper, we propose a novel framework to classify STS which focuses on radio logically defined sub-regions, so-called 'habitats'. The distinctive habitats are regions where tumor evolution may be observed. We assess T1 post- and pre-contrast gadolinium and T2 non-contrast Magnetic Resonance Images (MRIs) of 36 patients prior to treatment. This paper considers spatially distinct habitats, which may be helpful in clinical treatment, especially chemotherapy and radiation. Our approach contains three main steps: (1) intra-tumor segmentation into habitats based on pixel intensity, (2) texture analysis within each distinctive habitat to capture heterogeneity, and (3) prediction of metastatic and necrotic tumor. The experimental results show the individual cases were correctly classified as metastatic or non-metastatic disease with 86.11% accuracy based on 5 features and for necrosis =90% or necrosis <; 90% with 81.81% accuracy based on 4 features by using several meta-classifiers.
A fast large-size production data transformation scheme for supporting smart manufacturing in semiconductor industry

In this paper, we propose a novel data transformation scheme over a big data platform, aiming at injecting production data from the local database in the factory side and transforming them into the workpiece-centric form that many manufacturing analytics systems need. The key idea is to blend big data processing techniques, including table composition with external distributed files, columnar storage, partition, massively parallel processing into the data transformation scheme for minimizing the data processing time. Our proposed scheme brings two main impacts to the smart manufacturing. First, our scheme plays the key component to develop data-driven manufacturing decision systems, since large-volume production data sources can be efficiently transformed into the workpiece-centric form that other smart manufacturing services require. Second, our proposed scheme provides a development exemplar to assist a manufacturing factory toward the Industry-4.0 realm, since big data techniques are ingeniously blended in building data-intensive manufacturing services. We finally implement the prototype of the proposed scheme on the Hadoop platform and apply the prototype to a semiconductor factory for conducting integrated tests. Testing results of a case study physically applying the proposed scheme to a semiconductor factory demonstrate the success of our work.
Distal Renal Tubular Acidosis Associated with Isolated Large Vestibular Aqueduct and Sensorineural Hearing Loss

Distal renal tubular acidosis (dRTA) is characterized by a defect in urinary acidification with various degrees of metabolic acidosis; it can be inherited either as an autosomal dominant trait or as a recessive trait. The recessive form is associated in about one third of cases with progressive sensorineural hearing loss (SNHL). We performed a neuroradiological study in 3 consecutive unrelated pediatric patients affected with sporadic dRTA and progressive SNHL that disclosed an enlarged vestibular aqueduct (VA) and endolymphatic sac (ES) in each. The presence of an enlarged VA in our patients with dRTA and SNHL could contribute to the development, or at least the progression, of the hearing impairment. We suppose that the same molecular defect present in both the kidney and the inner ear could be the cause of dRTA and of the development of the enlarged VA and ES.
Cash Transfers and Child Nutrition: Pathways and Impacts

Childhood malnutrition remains a significant global problem, with an estimated 162 million children under the age of five suffering from stunted growth. This article examines the extent to which cash transfer programmes can improve child nutrition. It adopts a framework that captures and explains the pathways and determinants of child nutrition. The framework is then used to organize and discuss relevant evidence from the impact evaluation literature, focusing on impact pathways and new and emerging findings from sub-Saharan Africa to identify critical elements that determine child nutrition outcomes as well as knowledge gaps requiring further research, such as children’s dietary diversity, caregiver behaviours and stress.
Estimating gluconeogenesis by NMR isotopomer distribution analysis of [13C]bicarbonate and [1‐13C]lactate

The gluconeogenic contribution to glucose production in livers isolated from rats fasted for 24 h was determined by 13C‐NMR isotopomer distribution analysis of secreted glucose enriched from 99% [13C]bicarbonate (n = 4) and 99% [1‐13C]lactate (n = 4). Experiments with 3% 2H2O were also performed, allowing the gluconeogenic contribution to be measured by the relative 2H enrichments at positions 5 and 2 of glucose. From 13C‐NMR analyses, the contribution of gluconeogenesis to glucose output was estimated to be 93 ± 3% for [13C]bicarbonate perfusion and 91 ± 3% for [1‐13C]lactate perfusion, in good agreement with the 2H‐NMR analysis of the gluconeogenic contribution to glucose production (100 ± 1% and 99 ± 1%, respectively) and consistent with the expected negligible contribution from glycogenolysis. These results indicate that 13C‐NMR analysis of glucose 13C‐isotopomer distribution from either [13C]bicarbonate or [1‐13C]lactate precursor provides realistic estimates of the gluconeogenic contribution to hepatic glucose output.

Vector Competence of North American Mosquitoes (Diptera: Culicidae) for West Nile Virus

Abstract We evaluated the potential for several North American mosquito species to transmit the newly introduced West Nile (WN) virus. Mosquitoes collected in the New York City metropolitan area during the recent WN virus outbreak, at the Assateague Island Wildlife Refuge, VA, or from established colonies were allowed to feed on chickens infected with WN virus isolated from a crow that died during the 1999 outbreak. These mosquitoes were tested ≈2 wk later to determine infection, dissemination, and transmission rates. Aedes albopictus (Skuse), Aedes atropalpus (Coquillett), and Aedes japonicus (Theobald) were highly susceptible to infection, and nearly all individuals with a disseminated infection transmitted virus by bite. Culex pipiens L. and Aedes sollicitans (Walker) were moderately susceptible. In contrast, Aedes vexans (Meigen), Aedes aegypti (L.), and Aedes taeniorhynchus (Wiedemann) were relatively refractory to infection, but individual mosquitoes inoculated with WN virus did transmit virus by bite. Infected female Cx. pipiens transmitted WN virus to one of 1,618 F1 progeny, indicating the potential for vertical transmission of this virus. In addition to laboratory vector competence, host-feeding preferences, relative abundance, and season of activity also determine the role that these species could play in transmitting WN virus.
Application of the WHO alert level framework to cyanobacterial monitoring of Lake Champlain, Vermont

The increasing incidence of toxic cyanobacteria blooms worldwide has created a need for practical and efficient monitoring in order to protect public health. We developed a monitoring and alert framework based on World Health Organization (WHO) recommendations and applied it on Lake Champlain during the summers of 2002–2004. The protocol began with collection of net samples of phytoplankton in order to maximize the chance of finding potential toxin‐producing cyanobacteria. Samples were collected lakewide in partnership with ongoing monitoring efforts, but because open water sample sites did not capture conditions along the shoreline, we added near‐shore and shoreline stations in problem areas. Samples were examined qualitatively until potential toxin‐producing taxa were found. Then quantitative analyses began, using a rapid screening method to estimate cell density based on colony size. A final cell density of 4000 cells/mL triggered toxin analyses. Primary analysis was for microcystins using ELISA methods. Cell densities, locations of colonies, and toxin concentrations were reported weekly to public health officials. We found that screening for potential toxin‐producing cyanobacteria and then measuring toxin concentrations when cell densities reached critical levels worked well to identify problem locations. Although the WHO recommends using chlorophyll a concentration, it was not a good indicator of problem densities of potential toxin‐producing cyanobacteria. Our cell density screening method missed no developing blooms but produced less precise density estimates at high cell counts. Overall, our framework appears to provide an efficient and effective method for monitoring cyanotoxin risks. © 2006 Wiley Periodicals, Inc. Environ Toxicol 21: 278–288, 2006.
Cross-cultural adaptation, validity and reliability of the Arabic version of the Lower Extremity Functional Scale

Abstract Purpose: The aim was to translate and cross-culturally adapt the Lower Extremity Functional Scale (LEFS) into Arabic language and to examine its measurement properties in patients with musculoskeletal disorders of the lower extremity. Methods: Standard forward and backward translation followed by expert committee review, then preliminary testing was carried out to produce the final Arabic version of LEFS (LEFS-Ar). The test–retest reliability, measurement error, internal consistency and construct validity of the LEFS-Ar were examined in patients with musculoskeletal disorders of the lower extremity (N = 116). Results: The LEFS-Ar had excellent test–retest reliability (ICC2,1 = 0.96). LEFS-Ar standard error of measurement was 3.5 points while the minimal detectable change MDC95 was 9.8 points. LEFS-Ar showed excellent internal consistency with Cronbach’s alpha of 0.95. Parallel analysis and factor analysis showed that LEFS-Ar measures one underlying factor with all items loading heavily on this single factor. LEFS-Ar showed significant positive correlation with patient’s global assessment of function (r = 0.59) and that patients recovering from surgery reported lower LEFS-Ar score compared to patients with no surgery further supporting the construct validity of the LEFS-Ar. Conclusion: LEFS-Ar has excellent internal consistency, test–retest reliability with relatively small measurement error and is a valid measure of activity limitation due to lower extremity musculoskeletal disorders. All these measurement properties of the LEFS-Ar suggest the clinical usefulness of this measure. Implications for Rehabilitation The Arabic Lower Extremity Functional Scale (LEFS-Ar) is a reliable and valid measure of activity limitation due to lower extremity musculoskeletal disorders with relatively small measurement error. LEFS-Ar can be used in daily clinical practice and for research purposes to quantify activity limitation in Arabic-speaking individuals with lower extremity musculoskeletal disorders.
Bacteriologic and histologic features in mice after intranasal inoculation of Brucella melitensis.

OBJECTIVE To characterize effects of intranasal inoculation of virulent Brucella melitensis strain 16M in mice. ANIMALS Female Balb/c mice, 6 to 8 weeks old. PROCEDURE Studies were designed to elucidate gross morphologic lesions, bacterial burden in target organs, and histologic changes in tissues following experimental intranasal inoculation of mice with B melitensis 16M, which could be used to characterize a model for testing vaccine efficacy. RESULTS Measurable splenomegaly was evident at 3 and 7 weeks after inoculation. A demonstrable increase in splenic colony-forming units (CFU) from infected mice increased over time with increasing dose when comparing inocula of 10(3), 10(4), and 10(5) CFU. Recovery of brucellae from the lungs was possible early in infection with 10(1), 10(3), and 10(5) CFU, but only the group inoculated with 10(5) CFU consistently yielded quantifiable bacteria. At a dose of 10 CFU, few organisms were located in the spleen. Bacteria were recovered up to 140 days after inoculation in mice given 10(3) CFU. At an inoculum of 10(5) CFU, bacterial counts were highest early in infection. Histologic examination of tissues revealed an increase in white pulp and marginal zone in the spleen and lymphohistiocytic hepatitis. CONCLUSION AND CLINICAL RELEVANCE Changes in the spleen and liver increased with increases in dose and with increased time following intranasal inoculation with B melitensis 16M. Surprisingly, histologic changes were not observed in the lungs of inoculated mice.
Growth factor levels in the platelet-rich plasma produced by 2 different methods: curasan-type PRP kit versus PCCS PRP system.

PURPOSE Potential treatments using autologous thrombocyte growth factors are an important reason to improve methods for isolating platelet-rich plasma (PRP). Two methods for extracting PRP directly by the surgeon are currently available; this study was conducted to compare the growth factor levels in the resulting PRP. MATERIALS AND METHODS Whole blood was drawn from 46 healthy donors (17 men, 29 women) aged 20 to 59 years (29.9 +/- 7.8). PRP was then separated from each sample by both the PCCS (3i) and Curasan (PRP Kit, Curasan) methods. RESULTS The growth factor content differed significantly for TGF-beta1 (PCCS 467.1 ng/mL; Curasan 79.7 ng/mL) (sign test P < .0001) and PDGF-AB (PCCS 251.8 ng/mL; Curasan 314.1 ng/mL) (P < .0001); this was less significant for IGF-I (PCCS 91.0 ng//mL; Curasan 69.5 ng/mL) (P < .02). The higher platelet count in the PCCS PRP (PCCS 2,232,500/microL; Curasan 1,140,500/microL) seemed to correlate with a higher level of TGF-beta1 (Spearman's correlation coefficient, r(s) = 0.7), whereas the higher leukocyte count in the Curasan PRP (PCCS 15,300/microL; Curasan 33,150/pL) had only a minor correlation with higher levels of PDGF-AB (r(s) = 0.46). DISCUSSION The PCCS end product has both a higher platelet count and a higher total content of the growth factors investigated. Nevertheless, the biologic effect of the evaluated growth factor levels remains unknown. The amount of PRP necessary to achieve the intended biologic effects still remains unclear. CONCLUSION PRP contains growth factors in high concentrations. Precise predictions of growth factor levels based on the thrombocyte counts of whole blood or PRP appeared limited. There are different sources for growth factors (platelets, leukocytes, plasma).
Quantitative FRET Analysis With the E0GFP‐mCherry Fluorescent Protein Pair

Fluorescence resonance energy transfer (FRET) between fluorescent proteins (FPs) is a powerful tool to investigate protein–protein interaction and even protein modifications in living cells. Here, we analyze the E0GFP‐mCherry pair and show that it can yield a reproducible quantitative determination of the energy transfer efficiency both in vivo and in vitro. The photophysics of the two proteins is reported and shows good spectral overlap (Förster radius R0 = 51 Å), low crosstalk between acceptor and donor channels, and independence of the emission spectra from pH and halide ion concentration. Acceptor photobleaching (APB) and one‐ and two‐photon fluorescence lifetime imaging microscopy (FLIM) are used to quantitatively determine FRET efficiency values. A FRET standard is introduced based on a tandem construct comprising donor and acceptor together with a 20 amino acid long cleavable peptidic linker. Reference values are obtained via enzymatic cleavage of the linker and are used as benchmarks for APB and FLIM data. E0GFP‐mCherry shows ideal properties for FLIM detection of FRET and yields high accuracy both in vitro and in vivo. Furthermore, the recently introduced phasor approach to FLIM is shown to yield straightforward and accurate two‐photon FRET efficiency data even in suboptimal experimental conditions. The consistence of these results with the reference method (both in vitro and in vivo) reveals that this new pair can be used for very effective quantitative FRET imaging.
Fact or Fiction

Subjective reporting polarizes competing viewpoints. However, helping readers to recognize subjective content leads to more impartial discussions. Towards this end, we develop machine learning models that classify sentence objectivity. We contribute a set of linguistic rules for determining sentence objectivity collated from previous work. We also develop a labeled dataset with over 5000 sentences retrieved from various news sources. Further, we evaluate traditional machine learning classification models and artificial neural networks on our dataset. The best performing model, a convolutional neural network, achieved an accuracy of 85% and an AUC of 0.933. Using our subjective-objective sentence classification model, we implement Fact-or-Fiction, an end-to-end web system that highlights objective sentences in user text. Fact-or-Fiction provides additional information, such as links to related web pages and related previous submissions.
Non-rigid object tracking

In this paper, we propose a new algorithm for optimally adapting ellipses outlining objects of interest in order to improve the performance of a colour based tracking approach for real video sequences. We present a Lagrangian based method to integrate a regularising component into the covariance matrix to be computed. Technically, we intend to reduce the residuals between the estimated probability distribution and the expected one. We argue that by doing so, the shape of the ellipse can be properly adapted in the tracking stage. Experimental results confirm that our proposed method leads to favourable performance in terms of shape adaption and object localisation.
