    2005-03-01

    In the field of Human Computer Interaction (HCI), we use a variety of Knowledge Elicitation (KE) techniques to capture user cognitive issues e.g. via interviews, paper prototyping, card sorting, focus group debates and more. MIKE (Mobile Interactive Knowledge Elicitation) is an ongoing research direction to enhance the KE capabilities of HCI practitioners via mobile and electronic methods. MIKE tools are a suite of Mobile HCI software and hardware configurations for a variety of mobile platforms. With MIKE's CONKER we describe a Collaborative Non-linear Knowledge Elicitation Repository for HCI practitioners. Its intention is to provide a scalable infrastructure for supporting the management and collaborative retrieval of mobile based KE datasets. Some of its functional design requirements include HCI practitioner profiles management, managing experimental progress from dispersed mobile HCI teams, timetabling expenditures for time critical empirical capture and participant management, and enabling concurrent HCI specialists to compare elicited mobile data. Further expansion of the CONKER system will include incorporation of distributed psychometric analysis methods. CONKER is realized as a sourceforge-alike Web-Portal using state-of-the-art web-framework technologies. We describe several approaches to the capturing and management of HCI data and how CONKER makes this available to the HCI community.

  10. Music in Thomas Pynchon’s Mason & Dixon

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Through Pynchon-written songs, integration of Italian opera, instances of harmonic performance, dialogue with Plato’s 'Republic' and Benjamin Franklin’s glass armonica performance, 'Mason & Dixon 'extends, elaborates, and investigates Pynchon’s own standard musical practices. Pynchon’s investigation of the domestic, political, and theoretical dimensions of musical harmony in colonial America provides the focus for the novel’s historical, political, and aesthetic critique. Extending Pynchon’s career-long engagement with musical forms and cultures to unique levels of philosophical abstraction, in 'Mason & Dixon'’s consideration of the “inherent Vice” of harmony, Pynchon ultimately criticizes the tendency in his own fiction for characters and narrators to conceive of music in terms that rely on the tenuous and affective communal potentials of harmony.

    2013-04-01

    Two Svalbard's fjords - Hornsund (on the western side of the most southern part of Spitsbergen island) and Kongsfjorden (also on the western side of Spitsbergen island, but in the northern part) are quite different - the first one is "cold" and second one is "warm". It is obvious that both of them are under influence of West Spitsbergen Current (WSC), which curry out warm Atlantic water and cold East Spitsbergen Current detaches Hornsund. But there is also freshwater stored in Spitsbergen glaciers that have strong influence on local hydrology and physical fjord conditions. Both, local and shelf conditions have impact on state of the fjord and there is no answer which one is the most important in each fjord. Modeling could help to solve this problem - MIKE 3D model has been implemented for both fjords. Mesh-grid of the each fjord has been extended for covering shelf area. External forces like tides, velocities at the boundary and atmospheric forces together with sources of cold and dens fresh water in the fjords will give reliable representation of physical conditions in Hornsund and Kongsfjorden. Calculations of balances between cold fresh water and warm and salt will provide additional information that could help to answer the main question of the GAME (Growing of the Arctic Marine Ecosystem) project - what is the reaction of physically controlled Arctic marine ecosystem to temperature rise.

    Full Text Available To evaluate sources of error in the Magnetic Resonance Imaging (MRI measurement of percent fibroglandular tissue (%FGT using two-point Dixon sequences for fat-water separation.Ten female volunteers (median age: 31 yrs, range: 23-50 yrs gave informed consent following Research Ethics Committee approval. Each volunteer was scanned twice following repositioning to enable an estimation of measurement repeatability from high-resolution gradient-echo (GRE proton-density (PD-weighted Dixon sequences. Differences in measures of %FGT attributable to resolution, T1 weighting and sequence type were assessed by comparison of this Dixon sequence with low-resolution GRE PD-weighted Dixon data, and against gradient-echo (GRE or spin-echo (SE based T1-weighted Dixon datasets, respectively.%FGT measurement from high-resolution PD-weighted Dixon sequences had a coefficient of repeatability of ±4.3%. There was no significant difference in %FGT between high-resolution and low-resolution PD-weighted data. Values of %FGT from GRE and SE T1-weighted data were strongly correlated with that derived from PD-weighted data (r = 0.995 and 0.96, respectively. However, both sequences exhibited higher mean %FGT by 2.9% (p < 0.0001 and 12.6% (p < 0.0001, respectively, in comparison with PD-weighted data; the increase in %FGT from the SE T1-weighted sequence was significantly larger at lower breast densities.Although measurement of %FGT at low resolution is feasible, T1 weighting and sequence type impact on the accuracy of Dixon-based %FGT measurements; Dixon MRI protocols for %FGT measurement should be carefully considered, particularly for longitudinal or multi-centre studies.

  11. Validating Stormwater system simulations in Edmonton Using MIKE URBAN

    2016-12-01

    Many municipalities use chloramination to disinfect drinking water so as to avert the production of the disinfection by-products (DBPs) that result from conventional chlorination processes and the consequential public health risks. However, the long-lasting monochloramine disinfectant (NH2Cl) can pose a significant risk to the environment. As, it can be introduced into stormwater sewers and thus freshwater sources. This study was intended to investigate decay of NH2Cl in stormwater networks starting by building a stormwater model and validating its hydraulic and hydrologic computations, and then modelling water quality in the storm sewers. The presented work here is only the first stage of this study. The 30th Avenue basin in Edmonton was chosen as a case study, because it has various land-use types including commercial, industrial, residential and parks. The City of Edmonton has already built a MIKE-URBAN stormwater model for modelling floods. However, this model was built to the trunk level where only the main drainage features were presented. Also, this model was not calibrated and known to consistently compute pipe flows higher than the observed values; not to the benefit of studying water quality. So the first goal was to complete modelling and updating the real stormwater network. Then, available GIS Data was used to calculate different catchment properties such as slope, length and imperviousness. To calibrate and validate this model, data of two temporary pipe flow monitoring stations was used along with records of two other permanent stations available for eight consecutive summer seasons. The effect of various hydrological parameters on model results was investigated. It was found that model results were affected by the ratio of impervious areas. The catchment length was tested, however calculated, because it is approximate representation of the catchment shape. Surface roughness coefficients were calibrated using. Consequently, computed flows at the two

    To compare systematically quantitative MRI, MR spectroscopy (MRS), and different histological methods for liver fat quantification in order to identify possible incongruities. Fifty-nine consecutive patients with liver disorders were examined on a 3 T MRI system. Quantitative MRI was performed using a dual- and a six-echo variant of the modified Dixon (mDixon) sequence, calculating proton density fat fraction (PDFF) maps, in addition to single-voxel MRS. Histological fat quantification included estimation of the percentage of hepatocytes containing fat vesicles as well as semi-automatic quantification (qHisto) using tissue quantification software. In 33 of 59 patients, the hepatic fat fraction was >5 % as determined by MRS (maximum 45 %, mean 17 %). Dual-echo mDixon yielded systematically lower PDFF values than six-echo mDixon (mean difference 1.0 %; P < 0.001). Six-echo mDixon correlated excellently with MRS, qHisto, and the estimated percentage of hepatocytes containing fat vesicles (R = 0.984, 0.967, 0.941, respectively, all P < 0.001). Mean values obtained by the estimated percentage of hepatocytes containing fat were higher by a factor of 2.5 in comparison to qHisto. Six-echo mDixon and MRS showed the best agreement with values obtained by qHisto. Six-echo mDixon, MRS, and qHisto provide the most robust and congruent results and are therefore most appropriate for reliable quantification of liver fat. (orig.)

    The Dixon sequence is acquired for attenuation correction (AC) of positron emission tomography (PET) data in integrated PET/magnetic resonance (MR). However it sometimes misclassifies soft tissue and fat in μ-map. In the present study, we investigated factors related to this misclassification and their clinical impacts. Forty-eight oncological patients (19 males and 29 females, mean age: 59±11 years old) underwent a single fluorine-18 fluorodeoxyglucose ((18)F-FDG) injection/dualimaging protocol on PET/computed tomography (CT) and subsequently PET/MR. Patients were assigned to either of two groups; group A with a misclassification in at least one bed position or group B with a correctly classified μ-map. We compared body mass index (BMI), lean body mass, fasting duration, volume of hydration and age between group A and group B. In addition, we analyzed the impact of PET quantification using standard uptake ratio (SUR) defined as uptake in volume of interest/uptake in thigh muscle. The Dixon-AC SUR was compared with CT-AC SUR in misclassified bed positions and correctly classified bed positions. All patients were scanned in four bed positions by PET/MR. Ten patients were assigned to group A; six showed misclassification in a bed position (5 in head and 1 in abdomen), three patients in 3 bed positions (head-thorax-abdomen), and one patient in partial bed position in neck. Misclassification was observed in 21% of 48 patients. Group A and group B showed no statistically significant differences in BMI, lean body mass, fasting duration or age, however the volume of hydration in group A (245mL) was smaller than in group B (452.6mL) (P=0.027). In group A, we analyzed Dixon-AC SUR/CT-AC SUR ratios in 16 misclassified and 24 correctly classified regions, and ratios in these regions were significant different 0.80 and 0.93, respectively (P=0.046). Because no corrective method has been devised after a scan, we recommend that Dixon images with μ-maps should be checked

    In October through November 2006, scientists from the U. S. Geological Survey (USGS) Eastern Region Earth Surface Processes Team (EESPT) and the Raleigh (N.C.) Water Science Center (WSC), in cooperation with the North Carolina Geological Survey (NCGS) and the Onslow County Water and Sewer Authority (ONWASA), drilled a stratigraphic test hole and well in Onslow County, N.C. The Dixon corehole was cored on ONWASA water utility property north of the town of Dixon, N.C., in the Sneads Ferry 7.5-minute quadrangle at latitude 34deg33'35' N, longitude 77deg26'54' W (decimal degrees 34.559722 and -77.448333). The site elevation is 66.0 feet (ft) above mean sea level as determined using a Paulin precision altimeter. The corehole attained a total depth of 1,010 ft and was continuously cored by the USGS EESPT drilling crew. A groundwater monitoring well was installed in the screened interval between 234 and 254 ft below land surface. The section cored at this site includes Upper Cretaceous, Paleogene, and Neogene sediments. The Dixon core is stored at the NCGS Coastal Plain core storage facility in Raleigh. The Dixon corehole is the fourth and last in a series of planned North Carolina benchmark coreholes drilled by the USGS Coastal Carolina Project. These coreholes explore the physical stratigraphy, facies, and thickness of Cretaceous, Paleogene, and Neogene Coastal Plain sediments in North Carolina. Correlations of lithologies, facies, and sequence stratigraphy can be made with the Hope Plantation corehole, N.C., near Windsor in Bertie County (Weems and others, 2007); the Elizabethtown corehole, near Elizabethtown, N.C., in Bladen County (Self-Trail and others, 2004b); the Smith Elementary School corehole, near Cove City, N.C., in Craven County (Harris and Self-Trail, 2006; Crocetti, 2007); the Kure Beach corehole, near Wilmington, N.C., in New Hanover County (Self-Trail and others, 2004a); the Esso#1, Esso #2, Mobil #1, and Mobil #2 cores in Albermarle and Pamlico Sounds

    Renal dynamic contrast-enhanced (DCE) MRI provides information on renal perfusion and filtration. However, clinical implementation is hampered by challenges in postprocessing as a result of misalignment of the kidneys due to respiration. We propose to perform automated image registration using the fat-only images derived from a modified Dixon reconstruction of a dual-echo acquisition because these provide consistent contrast over the dynamic series. DCE data of 10 hypertensive patients was used. Dual-echo images were acquired at 1.5 T with temporal resolution of 3.9 s during contrast agent injection. Dixon fat, water, and in-phase and opposed-phase (OP) images were reconstructed. Postprocessing was automated. Registration was performed both to fat images and OP images for comparison. Perfusion and filtration values were extracted from a two-compartment model fit. Automatic registration to fat images performed better than automatic registration to OP images with visible contrast enhancement. Median vertical misalignment of the kidneys was 14 mm prior to registration, compared to 3 mm and 5 mm with registration to fat images and OP images, respectively (P = 0.03). Mean perfusion values and MR-based glomerular filtration rates (GFR) were 233 ± 64 mL/100 mL/min and 60 ± 36 mL/minute, respectively, based on fat-registered images. MR-based GFR correlated with creatinine-based GFR (P = 0.04) for fat-registered images. For unregistered and OP-registered images, this correlation was not significant. Absence of contrast changes on Dixon fat images improves registration in renal DCE MRI and enables automated postprocessing, resulting in a more accurate estimation of GFR.

    To quantify the muscle fat-content (MFC) in phantoms, volunteers and patients with achillodynia using two-point Dixon-based magnetic resonance imaging (2pt-MRI{sub DIXON}) in comparison to MR spectroscopy (MRS) and visual assessment of MFC. Two-point Dixon-based MRI was used to measure the MFC of 15 phantoms containing 0-100 % fat-content and calf muscles in 30 patients (13 women; 57 ± 15 years) with achillodynia and in 20 volunteers (10 women; 30 ± 14 years) at 1.5 T. The accuracy of 2pt-MRI{sub DIXON} in quantification of MFC was assessed in vitro using phantoms and in vivo using MRS as the standard of reference. Fat-fractions derived from 2pt-MRI{sub DIXON} (FF{sub DIXON}) and MRS (FF{sub MRS}) were related to visual assessment of MFC (Goutallier grades 0-4) and Achilles-tendon quality (grade 0-4). Excellent linear correlation was demonstrated for FF{sub DIXON} with phantoms and with FF{sub MRS} in patients (p{sub c} = 0.997/0.995; p < 0.001). FF{sub DIXON} of the gastrocnemius muscle was significantly higher (p = 0.002) in patients (7.0 % ± 4.7 %) compared with volunteers (3.6 % ± 0.7 %), whereas visual-grading showed no difference between both groups (p > 0.05). FF{sub MRS} and FF{sub DIXON} were significantly higher in subjects with (>grade 1) structural damage of the Achilles-tendon (p = 0.01). Two-point Dixon-based MRI allows for accurate quantification of MFC, outperforming visual assessment of calf muscle fat. Structural damage of the Achilles tendon is associated with a significantly higher MFC. (orig.)

    Dear readers and authors, June 3, 2012 will mark five months since Professor Igor Yevseyev, Deputy Editor-in-Chief of both journals Laser Physics and Laser Physics Letters passed away, suddenly and unexpectedly. He was 67. Born in Moscow, he entered one of the world's best schools of physics, Moscow Engineering Physics Institute (MEPhI). With this renowned educational and research institution he bonded an alliance for his entire life, starting as an undergraduate student in the Department of Theoretical Physics and later continued as graduate student, assistant professor, associated professor, and full professor in the same department, a rare accomplishment of a person. All those years he retained the love of his life—the love for physics. He worked tirelessly as a teacher and scholar in this captivating field of knowledge. Professor Yevseyev was one of the founders of the international journal of Laser Physics in 1990, the first academic English language journal published in the former USSR. Later, in 2004, the second journal, Laser Physics Letters was brought to the forum of global laser physics community. The idea behind this new title was Professor Yevseyev's initiative to reach the readers and participants with new pioneering and break-through research results more rapidly. His leadership and indefatigable dedication to the quality of published materials made it possible that this journal reached international recognition in a few short years. Still, in order to attract even more attention of potential contributors and readers, Professor Yevseyev originally proposed to conduct the International Laser Physics Workshop (LPHYS) on the annual basis. Since 1992 the Workshop has been conducted every year, each year in a different country. As in all previous years, Professor Yevseyev was the key organizer of this year's workshop in Calgary, Canada. Sadly, this workshop will take place without him. Editorial Board

    Full Text Available Purpose: To evaluate a potential approach for improved attenuation correction (AC of PET in simultaneous PET and MRI brain imaging, a straightforward approach that adds bone information missing on Dixon AC was explored. Methods: Bone information derived from individual T1-weighted MRI data using segmentation tools in SPM8, were added to the standard Dixon AC map. Percent relative difference between PET reconstructed with Dixon+bone and with Dixon AC maps were compared across brain regions of 13 oncology patients. The clinical potential of the improved Dixon AC was investigated by comparing relative perfusion (rCBF measured with arterial spin labeling to relative glucose uptake (rPETdxbone measured simultaneously with 18F-flurodexoyglucose in several regions across the brain. Results: A gradual increase in PET signal from center to the edge of the brain was observed in PET reconstructed with Dixon+bone. A 5-20% reduction in regional PET signals were observed in data corrected with standard Dixon AC maps. These regional underestimations of PET were either reduced or removed when Dixon+bone AC was applied. The mean relative correlation coefficient between rCBF and rPETdxbone was r = 0.53 (p<0.001. Marked regional variations in rCBF-to-rPET correlation were observed, with the highest associations in the caudate and cingulate and the lowest in limbic structures. All findings were well matched to observations from previous studies conducted with PET data reconstructed with computed tomography derived AC maps. Conclusion: Adding bone information derived from T1-weighted MRI to Dixon AC maps can improve underestimation of PET activity in hybrid PET-MRI neuroimaging.

    To evaluate quantification of early fatty infiltration in supraspinatus muscles with magnetic resonance (MR) imaging using a T2*-corrected multi-echo 3D-gradient-echo Dixon-based sequence (multi-echo Dixon) and compare it to proton-MR-spectroscopy. Sixty subjects (mean age 46 years, 41 men) with good supraspinatus muscle quality on 1.5 T MR imaging were included. Fat percentage (FP) in the supraspinatus muscle was quantified using a multi-echo Dixon compared to single-voxel MR spectroscopy as reference standard. In 18 subjects the multi-echo Dixon was repeated to assess test-retest reliability. Measurements based on multi-echo Dixon were performed by two independent readers by placing regions-of-interest (ROIs) in the supraspinatus muscle corresponding to the MR-spectroscopy voxel. Intraclass and concordance correlation coefficients (ICC/CCC) were used for statistical analysis. Test-retest reliability was substantial for reader 1 (ICC = 0.757) and almost perfect for reader 2 (ICC = 0.873). Inter-reader reliability for multi-echo Dixon was almost perfect (ICC = 0.893, P <.0005). Mean FP in all 60 subjects with multi-echo Dixon was 3.5 ± 1.6 for reader 1, 3.7 ± 1.8 for reader 2, and 2.8 ± 1.4 with MR spectroscopy. Correlation between multi-echo Dixon and MR spectroscopy was moderate (CCC = 0.641). The multi-echo Dixon sequence is a reliable method and comparable to MR-spectroscopy for quantification of low levels of fatty infiltration in the supraspinatus muscle. (orig.)

    Simultaneous PET/MR of the brain is a promising technology for characterizing patients with suspected cognitive impairment or epilepsy. Unlike CT, however, MR signal intensities do not correlate directly with PET photon attenuation correction (AC), and inaccurate radiotracer SUV estimation can limit future PET/MR clinical applications. We tested a novel AC method that supplements standard Dixon-based tissue segmentation with a superimposed model-based bone compartment. We directly compared SUV estimation between MR-based AC and reference CT AC in 16 patients undergoing same-day PET/CT and PET/MR with a single (18)F-FDG dose for suspected neurodegeneration. Three Dixon-based MR AC methods were compared with CT: standard Dixon 4-compartment segmentation alone, Dixon with a superimposed model-based bone compartment, and Dixon with a superimposed bone compartment and linear AC optimized specifically for brain tissue. The brain was segmented using a 3-dimensional T1-weighted volumetric MR sequence, and SUV estimations were compared with CT AC for whole-image, whole-brain, and 91 FreeSurfer-based regions of interest. Modifying the linear AC value specifically for brain and superimposing a model-based bone compartment reduced the whole-brain SUV estimation bias of Dixon-based PET/MR AC by 95% compared with reference CT AC (P < 0.05), resulting in a residual -0.3% whole-brain SUVmean bias. Further, brain regional analysis demonstrated only 3 frontal lobe regions with an SUV estimation bias of 5% or greater (P < 0.05). These biases appeared to correlate with high individual variability in frontal bone thickness and pneumatization. Bone compartment and linear AC modifications result in a highly accurate MR AC method in subjects with suspected neurodegeneration. This prototype MR AC solution appears equivalent to other recently proposed solutions and does not require additional MR sequences and scanning time. These data also suggest that exclusively model-based MR AC

    Our aim was to develop a partial volume (PV) correction method of choline (Cho) signals detected by breast 3D-magnetic resonance spectroscopic imaging (3D-MRSI), using information from water/fat-Dixon MRI. Following institutional review board approval, five breast cancer patients were measured at 3 T. 3D-MRSI (1 cm{sup 3} resolution, duration ∝11 min) and Dixon MRI (1 mm{sup 3}, ∝2 min) were measured in vivo and in phantoms. Glandular/lesion tissue was segmented from water/fat-Dixon MRI and transformed to match the resolution of 3D-MRSI. The resulting PV values were used to correct Cho signals. Our method was validated on a two-compartment phantom (choline/water and oil). PV values were correlated with the spectroscopic water signal. Cho signal variability, caused by partial-water/fat content, was tested in 3D-MRSI voxels located in/near malignant lesions. Phantom measurements showed good correlation (r = 0.99) with quantified 3D-MRSI water signals, and better homogeneity after correction. The dependence of the quantified Cho signal on the water/fat voxel composition was significantly (p < 0.05) reduced using Dixon MRI-based PV correction, compared to the original uncorrected data (1.60-fold to 3.12-fold) in patients. The proposed method allows quantification of the Cho signal in glandular/lesion tissue independent of water/fat composition in breast 3D-MRSI. This can improve the reproducibility of breast 3D-MRSI, particularly important for therapy monitoring. (orig.)

    Quantitative MRI techniques detect disease progression in myopathies more sensitively than muscle function measures or conventional MRI. To date, only conventional MRI data using visual rating scales are available for measurement of disease progression in Becker muscular dystrophy (BMD). In 3 patients with BMD (mean age 36.8 years), the mean fat fraction (MFF) of the thigh muscles was assessed by MRI at baseline and at 1-year follow-up using a 2-point Dixon approach (2PD). The motor function measurement scale (MFM) was used for clinical assessment. The mean MFF of all muscles at baseline was 61.6% (SD 7.6). It increased by 3.7% to 65.3% (SD 4.7) at follow-up. The severity of muscle involvement varied between various muscle groups. As in other myopathies, 2PD can quantify fatty muscle degeneration in BMD and can detect disease progression in a small sample size and at relatively short imaging intervals. © 2015 Wiley Periodicals, Inc.

  20. Mathisson-Papapetrou-Tulczyjew-Dixon equations in ultra-relativistic regime and gravimagnetic moment

    Science.gov (United States)

    Deriglazov, Alexei A.; Ramírez, Walberto Guzmán

    Mathisson-Papapetrou-Tulczyjew-Dixon (MPTD) equations in the Lagrangian formulation correspond to the minimal interaction of spin with gravity. Due to the interaction, in the Lagrangian equations instead of the original metric g emerges spin-dependent effective metric G = g + h(S). So we need to decide, which of them the MPTD particle sees as the spacetime metric. We show that the MPTD equations, if considered with respect to the original metric (using the standard Landau-Lifshitz spacetime decomposition), have unexpected behavior: the acceleration in the direction of the velocity grows up to infinity in the ultra-relativistic limit. If considered with respect to G, the theory does not have this problem. But the metric now depends on spin, so there is no unique spacetime manifold for the universe of spinning particles: each particle probes its own three-dimensional (3D) geometry. This can be improved by adding a nonminimal interaction, given the modified MPTD equations with reasonable behavior within the original metric.

    To develop a method of suppressing the multi-resonance fat signal in diffusion-weighted imaging of skeletal muscle. This is particularly important when imaging patients with muscular dystrophies, a group of diseases which cause gradual replacement of muscle tissue by fat. The signal from the olefinic fat peak at 5.3 ppm can significantly confound diffusion-tensor imaging measurements. Dixon olefinic fat suppression (DOFS), a magnitude-based chemical-shift-based method of suppressing the olefinic peak, is proposed. It is verified in vivo by performing diffusion tensor imaging (DTI)-based quantification in the lower leg of seven healthy volunteers, and compared to two previously described fat-suppression techniques in regions with and without fat contamination. In the region without fat contamination, DOFS produces similar results to existing techniques, whereas in muscle contaminated by subcutaneous fat signal moved due to the chemical shift artefact, it consistently showed significantly higher (P = 0.018) mean diffusivity (MD). Because fat presence lowers MD, this suggests improved fat suppression. DOFS offers superior fat suppression and enhances quantitative measurements in the muscle in the presence of fat. DOFS is an alternative to spectral olefinic fat suppression.

    In ’Science as a vacation’, Michael Lynch argues that ’STS might aim for something other than the serious job of doing business’.

    Full Text Available Incredibile ma vero: il professor Mitja Skubic si trova, questa volta lui stesso, al centro dell’attenzione anziché essere il motore, il perno dell’attività. La ragione per questo attimo di respiro è il suo ottantesimo compleanno, a dire il vero passato già da tempo. È pressoché una contingenza aneddotica quella per cui il volume dedicatogli per l’occasione viene pubblicato così tardi: il professore ha continuato a tener d’occhio la nostra rivista ben dopo aver nominato i nuovi direttori tanto che sarebbe stato impossibile sorprenderlo con una miscellanea di contributi in suo onore.

    Full Text Available Professores/as são testemunhas do fantástico mundo da sexualidade. Esse artigo explora a centralidade de Eros para a educação e estabelece uma relação entre o desejo do/a professor/a e os acontecimentos emocionais da relação própria relação aluno/professor. Eu proponho que o aprendizado deva envolver nosso "eu" erótico, além das nossas fantasias. Mas esta perspectiva requer que professores/as considerem uma psicologia do amor como um caminho principal para a as situações emocionais de Eros. Na sua conclusão este trabalho sugere uma pedagogia que dê as boas vindas tanto à homossexualidade como a heterossexualidade como expressões humanas do amor.Teachers bear witness to the wondrous world of sexuality. This essay explores the centrality of Eros to education and links the teacher's desire to the emotional situation of the student/teacher relationship. I propose that learning involves our erotic selves and our fantasy life. But such a view requires that teachers consider a psychology of love as lending insight into the emotional situation of Eros. The paper concludes by suggesting a pedagogy that welcomes homosexuality and heterosexuality as human expressions of love.

    Fetal fat is indicative of the energy balance within the fetus, which may be disrupted in pregnancy complications such as fetal growth restriction, macrosomia, and gestational diabetes. Water-fat separated MRI is a technique sensitive to tissue lipid content, measured as fat fraction (FF), and can be used to accurately measure fat volumes. Modified two-point Dixon and chemical shift encoded MRI (CSE-MRI) are water-fat separated MRI techniques that could be applied to imaging of fetal fat. Modified two-point Dixon has biases present that are corrected in CSE-MRI which may contribute to differences in the fat measurements. To compare the measurement of fetal fat volume and FF by modified two-point Dixon and CSE-MRI. Cross-sectional study for comparison of two MRI pulse sequences. Twenty-one pregnant women with singleton pregnancies. 1.5T, modified two-point Dixon and CSE-MRI. Manual segmentation of total fetal fat volume and mean FF from modified 2-point Dixon and CSE-MRI FF images. Reliability was assessed by calculating the intraclass correlation coefficient (ICC). Agreement was assessed using a one-sample t-test on the fat measurements difference values (modified two-point Dixon - CSE-MRI). The difference scores were tested against a value of 0, which would indicate that the measurements were identical. The fat volume and FF measured by modified two-point Dixon and CSE-MRI had excellent reliability, demonstrated by ICCs of 0.93 (P < 0.001) and 0.90 (P < 0.001), respectively. They were not in agreement, with CSE-MRI giving mean fat volumes 180 mL greater and mean FF 3.0% smaller than modified two-point Dixon. The reliability between modified two-point Dixon and CSE-MRI indicates that either technique can be used to compare fetal fat measurements in different participants, but they are not in agreement possibly due to uncorrected biases in modified two-point Dixon. 4 Technical Efficacy: Stage 1 J.

The choice of Hadrian’s Villa (instead of a San Francisco devastated by the earthquake of 1906 as a background for the scenes which take place in the Paradise can be understood as coherent with Kushner’s ideological perspective, as well as with his original camp aesthetics.

    Knowledge Elicitation (KE) methods are an integral part of Human Computer Interaction (HCI) practices. They are a key aspect to the synthesis of psychology empirical methods with requirements engineering, User Centred Design (UCD) and user evaluations. Examples of these methods include prototyping, focus groups, interviews, surveys and direct video observation. The MIKE project (Mobile Interactive Knowledge Elicitation) at the Centre for HCI Design, City University London, UK provides mobile cyberscience capabilities for HCI practitioners conducting such research while at stakeholder locations. This paper reports on the design and development of a new MIKE based tool, named PET, a Participant-based Experiment Tracking tool for HCI practitioners using Java-based (J2ME) mobile devices. PET integrates its user tracking techniques with the development of the second generation implementation of the CONKER (COllaborative Non-linear Knowledge Elicitation Repository) Web Service. We thus report further on CONKER v2.0's new capabilities developed to enable tighter collaboration and empirical data management between HCI practitioners, considering their UCD needs. The visualisation, tracking and recording of HCI participant-based datasets via PET is explored with close connectivity with the CONKER v2.0 Web Service, in order to provide mobile-web cyberscience for remote and local HCI practitioners.

  12. Clues of Early Life: Dixon Island–Cleaverville Drilling Project (DXCL-DP in the Pilbara Craton of Western Australia

    Full Text Available The Pilbara Craton in NW Australia (Fig. 1 exposes one of the well-preserved and least -metamorphosed greenstone belts in the Archean. Greenstone belts are normally composed of a complex amalgam of meta-basaltic and meta-sedimentary rocks. Sedimentary rocks of the greenstone belts are good targets to search for clues of early Earth's environment and life. In recent years, several scientific drilling programs (e.g.: Archean Biosphere Drilling Project (ABDP, Ohmoto et al., 2006; Deep Time Drilling Project (DTDP, Anbar et al., 2007, Kaufman et al., 2007; PDP: Pilbara Drilling Project, Philippot et al., 2007 were successfully completed in the western Pilbara area, where 3.5, 2.9, 2.7, and 2.5 Ga sedimentary units were drilled. However, there is a huge time gap in the samples drilled by ABDP and DTDP that represents middle Archean time , between 3.5 Ga and 2.9 Ga (i.e., ~600 Ma, equivalent to the duration of the entire Phanerozoic. The Cleaverville-Dixon Island area of the coastal Pilbara terrain (Fig. 1 is suited to filling in the missing record. It contains well-preserved volcanosedimentary sequences (Cleaverville Group dated at 3.2 Ga where hydrothermal vein systems, organic-rich siliceoussedimentary rocks, and iron-rich sedimentary rocks are developed (Kiyokawa et al., 2006. Such geological materials may be used to reconstruct past submarine hydrothermal activity and its influence on biological activity. Indeed, some attempts have been made to answer the key questions. However, the surface outcrops in this area are generally weathered to variable degrees; thus they are apparently notsuitable for geo-biological and geochemical studies which require unaltered original chemical/isotopic compositions from the time of their formation in the middle Archean. Consequently, we carried out the “Dixon Island - Cleaverville Drilling Project (DXCL-DP”, to obtain “fresh” samples from the sedimentary sequences in the Cleaverville—Dixon Island area.

    The purpose of our study was to assess the value of a modified three-point Dixon MR technique for evaluating articular cartilage defects in the knee joint on a low-field-strength open magnet, correlated with arthroscopy. Twenty consecutive patients who underwent both MR imaging and arthroscopy of the knee joint for suspected internal derangement were examined. A modified three-point Dixon MR sequence with a single radiofrequency echo single-scan method for water and fat separation with correction of the static field inhomogeneities was performed on a 0.35-T open magnet to obtain fat suppression. The MR images were prospectively evaluated for the presence and grade of articular cartilage defects. Uniform fat suppression was obtained in all patients using the modified three-point Dixon technique. Fifty-nine cartilage abnormalities were identified in 19 patients on the basis of arthroscopy. Forty-seven of 59 arthroscopically proven abnormalities were prospectively detected on MR imaging. Compared with arthroscopy, the overall sensitivity of the modified three-point Dixon technique in detecting cartilage lesions was 80% and the specificity was 73%. Sixty-five percent of the cartilage abnormalities were graded identically on MR imaging and arthroscopy. The modified three-point Dixon sequence is a useful technique for achieving fat suppression in the knee joint on a 0.35-T open magnet. It is a sensitive and specific technique for the assessment of cartilage abnormalities in the knee.

    To compare two fat suppression techniques used for 3D T1-weighted sequence in breast MRI (magnetic resonance imaging), namely Dixon versus spectral fat saturation (fat sat). All breast MRI examinations performed in a Philips 3 T unit between March 2013 and October 2015 including either a Dixon or a fat sat sequence were retrospectively analyzed. The examinations were subjectively evaluated by two independent experienced readers in a scale of 5 for overall quality of fat suppression, homogeneity of fat suppression, definition of anatomic structures and focal lesions, diagnostic confidence for axillary and internal mammary regions and the presence of artifacts, 1 corresponding to excellent and 5 to non-diagnostic quality. Contrast-to-noise-ratio (CNR) measurements for muscle and focal lesions were also performed. Overall 161 women (mean age 51.6 ± 12.0 years) underwent 189 MR examinations, 113 with the fat saturation and 76 with the Dixon sequence. Interobserver variability was good (kappa = 0.757). In all subjectively evaluated parameters, the Dixon sequence was superior to the fat sat (p fat sat and 18.3 (±10.4) and 29.3 (±14.1) for the Dixon sequence, respectively (p fat sat for dedicated breast MRI at 3 T, in terms of efficiency of fat suppression and image quality with the added advantage of optimal exploration of the axillary areas.

    Stratigraphic transition of black chert to iron-rich sedimentary rocks above volcanic sequences with hydrothermal systems is common and characteristic feature of Archean greenstone belts. The 3.2 Ga Dixon Island Formation, exposed along the northern coast of Dixon Island located in the coastal Pilbara terrane, Western Australia, is one of such units and the focus of our study. We introduce field occurrence and lithology of the Dixon Island Formation that preserves features of paleohydrohermal environment in the Mesoarchean ocean. The Dixon Island Formation is composed of the following three members (in ascending order): Komatiite-Rhyolite Tuff, Black Chert, and Varicolored Chert members (Kiyokawa and Taira, 1998). Here we focus on the Komatiite-Rholite Tuff member. It preserves two cycles of highly altered komatiite lavas and well-stratified rhyolite tuff. Komatiite lavas include dendritic crystals of chrome spinel and ghosts of spinifex, euhedral and sheet-like olivines and pyroxenes. These rocks are now composed of granular microcrystalline quartz with chromian muscovite, chrome spinel and chrorite that formed by intense silicification. Its upper part contains hydrothermal veining and alteration (i.e., many vein swarms composed of veins of quartz and organic carbon-rich black chert). Most black chert veins intrude vertically into overlying layers, and contain barite, pyrite, monazite and clay minerals which were least affected by silicificatio. Based on the cross-cutting relationship seen in the outcrops, we recognized two generations of black chert veins (type 1 and type 2 veins; Kiyokawa et al., 2006). Type 1 veins are mainly composed of carbonaceous peloids in a microcrystalline quartz matrix. Euhedral and xenocrystic tourmaline are found only in Type1 veins. Type 2 veins are organic carbon-poor and contain fragments of black chert and siliceous volcanic breccia (Kiyokawa et al., 2006).

    Full Text Available This article aims to carry out a multidisciplinary reading of 'Mason & Dixon' starting from the apparitions of what might only look like a "stage prop", a rifle in four more or less important moments of the novel. By applying a stereoscopic reading of the novel, which may achieve depth by means of comparing different textual objects and a wider historical context (that of the history of firearms in the 17th and 18th century, plus other works by Pynchon featuring firearms, it will be shown how literary (textual avatars of "real", "historical" objects (firearms may at the same time be verbal constructs but refer to the technical, material features of those objects, establishing multi-dimensional and complex relations between technology, science, economics (early forms of globalization, politics (colonialism and colonial wars within and outside 'Mason & Dixon', and the rest of Pynchon's oeuvre. Moreover, this reading allows us to better understand how Pynchon may use the historical documents and literature he has found while researching his novels.

    To assess whether multi-echo Dixon magnetic resonance (MR) imaging with simultaneous T2{sup *} estimation and correction yields more accurate fat-signal fraction (FF) measurement of the lumbar paravertebral muscles, in comparison with non-T2{sup *}-corrected two-echo Dixon or T2{sup *}-corrected three-echo Dixon, using the FF measurements from single-voxel MR spectroscopy as the reference standard. Sixty patients with low back pain underwent MR imaging with a 1.5T scanner. FF mapping images automatically obtained using T2{sup *}-corrected Dixon technique with two (non-T2{sup *}-corrected), three, and six echoes, were compared with images from single-voxel MR spectroscopy at the paravertebral muscles on levels L4 through L5. FFs were measured directly by two radiologists, who independently drew the region of interest on the mapping images from the three sequences. A total of 117 spectroscopic measurements were performed either bilaterally (57 of 60 subjects) or unilaterally (3 of 60 subjects). The mean spectroscopic FF was 14.3 ± 11.7% (range, 1.9-63.7%). Interobserver agreement was excellent between the two radiologists. Lin's concordance correlation between the spectroscopic findings and all the imaging-based FFs were statistically significant (p < 0.001). FFs obtained from the T2*-corrected six-echo Dixon sequences showed a significantly better concordance with the spectroscopic data, with its concordance correlation coefficient being 0.99 and 0.98 (p < 0.001), as compared with two- or three-echo methods. T2{sup *}-corrected six-echo Dixon sequence would be a better option than two- or three-echo methods for noninvasive quantification of lumbar muscle fat quantification.

    Background Robust fat suppression remains essential in clinical MRI to improve tissue signal contrast, minimize fat-related artifacts, and enhance image quality. Purpose To compare fat suppression between mDIXON turbo spin echo (TSE) and conventional frequency-selective and inversion-recovery methods in pediatric spine MRI. Material and Methods Images from T1-weighted (T1W) and T2-weighted (T2W) TSE sequences coupled with conventional methods and the mDIXON technique were compared in 36 patients (5.8 ± 5.4 years) at 3.0 T. Images from 42 pairs of T1W (n = 16) and T2W (n = 26) scans were acquired. Two radiologists reviewed the data and rated images using a three-point scale in two categories, including the uniformity of fat suppression and overall diagnostic image quality. The Wilcoxon rank-sum test was used to compare the scores. Results The Cohen's kappa coefficient for inter-rater agreement was 0.69 (95% confidence interval [CI], 0.56-0.83). Images from mDIXON TSE were considered superior in fat suppression ( P fat suppression was superior using inversion-recovery and likewise in one case mDIXON had poorer image diagnostic quality. Lastly, mDIXON and conventional fat-suppression methods performed similarly in 17 (rater 1) and 14 (rater 2) cases, and yielded equal diagnostic image quality in 28 (rater 1) and 30 (rater 2) cases. Conclusion Robust fat suppression can be achieved with mDixon TSE pediatric spine imaging at 3.0 T and should be considered as a permanent replacement of traditional methods, in particular frequency-selective techniques.

    Super Typhoon Haiyan hit the Philippines on 08 November 2013 causing massive destruction to the central part of the country. Arguably the strongest tropical cyclone to make landfall in recorded history, Haiyan caused 6,201 deaths and damages amounting to PhP 36,690,882,497.27 (USD 824,390,091.77). The typhoon also brought about destructive storm surges reaching up to 7 meters in height. A better understanding of storm surge is essential to the development of mechanisms to mitigate the effects of similar events. Thus, a computer simulation of Haiyan with the resulting wave heights and storm surge levels was made using MIKE 21 model -- a software used for many different coastal and marine engineering projects worldwide. Simulations were made using the Hydrodynamic Flexible Mesh (HD FM) model coupled with the Spectral Wave (SW) model of the software. This coupled approach allows accurate calculations of both surge water levels and wave crest heights for overtopping of coastal structures. The maximum mesh flexibility of MIKE 21 allows mesh refinement for the coastal areas of Tacloban City within coarser mesh elements resulting to higher grid accuracy. Input parameters for the simulations of the coastline of Tacloban City, a densely populated coastal community heaviest hit by the storm surges of Haiyan, were obtained from the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) and Japan Meteorological Agency (JMA). Atmospheric conditions such as wind and pressure values were input to a set of regional and local hydrodynamic and spectral wave models. Simulation results were compared with available tidal gauge records and the comparison showed good correlation. Coastal regional inundation maps were then created from the results of the storm surge simulations. These maps or its equivalent should be used to develop and further improve disaster risk management plans for future surge events. These plans include, but are not limited to

    2009-02-01

    Recently, Mike and Farmer have constructed a very powerful and realistic behavioral model to mimick the dynamic process of stock price formation based on the empirical regularities of order placement and cancelation in a purely order-driven market, which can successfully reproduce the whole distribution of returns, not only the well-known power-law tails, together with several other important stylized facts. There are three key ingredients in the Mike-Farmer (MF) model: the long memory of order signs characterized by the Hurst index Hs, the distribution of relative order prices x in reference to the same best price described by a Student distribution (or Tsallis’ q-Gaussian), and the dynamics of order cancelation. They showed that different values of the Hurst index Hs and the freedom degree αx of the Student distribution can always produce power-law tails in the return distribution fr(r) with different tail exponent αr. In this paper, we study the origin of the power-law tails of the return distribution fr(r) in the MF model, based on extensive simulations with different combinations of the left part L(x) for x 0 of fx(x). We find that power-law tails appear only when L(x) has a power-law tail, no matter R(x) has a power-law tail or not. In addition, we find that the distributions of returns in the MF model at different timescales can be well modeled by the Student distributions, whose tail exponents are close to the well-known cubic law and increase with the timescale.

    The MIKE SHE model is able to simulate the entire stream flow which includes direct and basic flow. Many models either do not simulate or use simplistic methods to determine the basic flow. The MIKE SHE model takes into account many hydrological data. Since this study was directed towards the simulation of surface runoff and infiltration into saturated and unsaturated zone, the MIKE SHE is an appropriate model for reliable conclusions. In the current research, the MIKE SHE model was used to simulate runoff in the area of Sperchios River basin. Meteorological data from eight rainfall stations within the Sperchios River basin were used as inputs. Vegetation as well as geological data was used to perform the calibration and validation of the physical processes of the model. Additionally, ArcGIS program was used. The results indicated that the model was able to simulate the surface runoff satisfactorily, representing all the hydrological data adequately. Some minor differentiations appeared which can be eliminated with the appropriate adjustments that can be decided by the researcher's experience.

    This study was undertaken to develop and cross-validate reference and individual predictive models for estimating functional thigh muscle cross-sectional area (TCSA) by 2-point Dixon magnetic resonance imaging (MRI). TCSAs of dominant sides at the mid-thigh level were measured by 2-point Dixon MRI (MRITCSA). Functional MRITCSA were compared with the predictive models in a sample of 92 younger (20-40 years; 28.55±4.87; n=50) and older (>65years; 71.22±4.82; n=42) Koreans. Lean body masses were measured by dual energy X-ray absorptiometry (DXALBM), and thigh isokinetic muscle strengths, extension peak torque at 60°/sec, were measured using a Biodex® dynamometer (BiodexEPT). Multiple regression analysis generated the reference model (R2=0.75 and SEE=1472.63mm2 (8%)) as follows: The reference model: functional TCSA(mm2)=-1230.49+62.81*height+3061.78*gender -2692.57*age+58.91*weight. The individual model (R2=0.80, SEE=1158.34mm2 (7%)) was as follows: The individual model: functional TCSA(mm2)=1631.62+1.76* DXALBM+9.51*BiodexEPT where height is in centimeters; weight is in kilograms; for gender, female=0 and male=1; and for age, age under 40=1 and age over 65=2. PRESS statistics of R2 and SEE were 0.78 and 1382.98mm2 for the reference model, and 0.88 and 979.02mm2 for the individual model. The 2-point Dixon MRI appears to be valid for measuring functional muscle size. Our results suggest that the reference and individual models provide acceptable estimates of functional thigh muscle CSA in healthy Korean adults. Therefore, the models developed in the study could be useful as a research tool to establish indexes for functional muscle composition in healthy Koreans. Copyright © 2016 Elsevier Ireland Ltd.

    Aarhus University offers a mandatory pedagogical training program for assistant professors, required in order to obtain tenure at a Danish university. At Business and Social Sciences, this program is supplemented by voluntary observation and (first of all formative) supervision of the assistant...... professors’ teaching practice. This offer is given is (i) because many young university teachers face problems putting pedagogical theory into practice – even though the program mentioned is practice-oriented, and (ii) because many of them (partly due to (i)) lack self-confidence as to teaching....... The presentation will discuss the theoretical framework of the supervision given and compare it to other supervision models. Furthermore it will address the need of working with supervision in a SOTL context. Attendees will be activated through discussion of short prototypical cases. A possible – and desired...

  10. Observations on Professor Hayek's Plan

    Ludwig von Mises

    2009-01-01

    Full Text Available This memorandum was written at the request of Henry Hazlitt to provide Mises’s comments on and concerns about F.A. Hayek’s initial proposals for what became the Mont Pèlerin Society. Mises stresses that those who favor liberty and freedom and oppose totalitarianism must also oppose interventionism. The memo argues that those who fought and lost against the rising tide of totalitarianism at the turn of the 20th Century lost their battles because they settled for middle-of-the-road policies that conceded considerable ground to the socialists. The weak point in Professor Hayek’s plan is that it relies upon the cooperation of many men who are today’s middle-of-the-roaders. As interventionists, they may not be the hoped-for intellectual pioneers to inspire people to build a freer world.

    Camillo Negro, Professor in Neurology at the University of Torino, was a pioneer of scientific film. From 1906 to 1908, with the help of his assistant Giuseppe Roasenda and in collaboration with Roberto Omegna, one of the most experienced cinematographers in Italy, he filmed some of his patients for scientific and educational purposes. During the war years, he continued his scientific film project at the Military Hospital in Torino, filming shell-shocked soldiers. In autumn 2011, the Museo Nazionale del Cinema, in partnership with the Faculty of Neurosciences of the University of Torino, presented a new critical edition of the neuropathological films directed by Negro. The Museum's collection also includes 16 mm footage probably filmed in 1930 by Doctor Fedele Negro, Camillo's son. One of these films is devoted to celebrating the effects of the so-called "Bulgarian cure" on Parkinson's disease.

  15. Fat-constrained 18F-FDG PET reconstruction using Dixon MR imaging and the origin ensemble algorithm

    Combined PET/MR imaging allows to incorporate the high-resolution anatomical information delivered by MRI into the PET reconstruction algorithm for improvement of PET accuracy beyond standard corrections. We used the working hypothesis that glucose uptake in adipose tissue is low. Thus, our aim was to shift 18F-FDG PET signal into image regions with a low fat content. Dixon MR imaging can be used to generate fat-only images via the water/fat chemical shift difference. On the other hand, the Origin Ensemble (OE) algorithm, a novel Markov chain Monte Carlo method, allows to reconstruct PET data without the use of forward- and back projection operations. By adequate modifications to the Markov chain transition kernel, it is possible to include anatomical a priori knowledge into the OE algorithm. In this work, we used the OE algorithm to reconstruct PET data of a modified IEC/NEMA Body Phantom simulating body water/fat composition. Reconstruction was performed 1) natively, 2) informed with the Dixon MR fat image to down-weight 18F-FDG signal in fatty tissue compartments in favor of adjacent regions, and 3) informed with the fat image to up-weight 18F-FDG signal in fatty tissue compartments, for control purposes. Image intensity profiles confirmed the visibly improved contrast and reduced partial volume effect at water/fat interfaces. We observed a 17+/-2% increased SNR of hot lesions surrounded by fat, while image quality was almost completely retained in fat-free image regions. An additional in vivo experiment proved the applicability of the presented technique in practice, and again verified the beneficial impact of fat-constrained OE reconstruction on PET image quality.

  17. An editorial approach: Mike Nelson’s corridors and The Deliverance and The Patience

    Full Text Available This essay contrasts the contemporary British artist Mike Nelson’s approach to constructing his large, multi-room installations with his approach to editing the numerous artist books that he has produced since 2000. This comparison reveals several compositional symmetries between the two, namely pertaining to narrative non-linearity and meta-fictionality. The logic of montage is shown to similarly underscore both the books and the installations. This essay argues that the corridors connecting the different rooms of Nelson’s installations function in a similar way to the logic of montage: they play an integral role as the support that binds the structure of the installation (its multiple rooms together as a whole. This essay argues that the corridor is the primary viewing framework of the installation for the viewer, and that this vantage point is significant because the necessarily partial vision of the installation from the space of the corridor demonstrates the logic of installation art more broadly. I conclude by mapping the key compositional elements of Nelson’s artist books onto his installations, taking the 2001 work The Deliverance and The Patience as a case study, to show that the books do not exemplify the artwork as with traditional exhibition catalogues, but rather parallel it. That is, a structural continuity is established between these two facets of his work.

  18. Memorial to Professor Antonio Barone

    Antonio Barone prematurely passed away on 4 December 2011 at the age of 72, after a one-year battle with cancer. He left behind his wife Sveva and his two sons, Alberto and Livio. Antonio was Professor Emeritus at the University of Napoli Federico II, where he had been teaching for about 40 years. The initial research activity of Antonio was in the field of nuclear physics. In this context, almost 45 years ago, the Ge 'Lithium drift' semiconductor detectors represented a novelty, due to the high energy resolution enabled by those devices. Superconductors stimulated new approaches to radiation detection and this motivated Antonio's interest towards superconductivity. Following the birth of the Laboratorio di Cibernetica of the CNR in 1967 he was given the opportunity to work on a joint USA-Italy project (University of Wisconsin, Madison and CNR Naples) in the field of superconductivity on the peculiar subject of the superconductive 'Neuristors'. His research activity on Josephson junctions opened up a wide variety of very stimulating subjects in which he was deeply involved, ranging from the soliton propagation in 'long' Josephson structures to fluctuations phenomena, from light-sensitive junctions and proximity effect to the development of innovative superconducting devices. The strong interaction of Antonio with the Landau Institute for Theoretical Physics of the Academy of Sciences in Moscow, characterizes a long period of his research activity with a precious merging of theoretical and experimental aspects. This body of work converged into the famous monograph on the 'Physics and Applications of the Josephson Effect', written in collaboration with Gianfranco Paternò in 1982. This rapidly became the reference text for the Josephson effect, as documented by thousands of citations and the fact that it was translated into Russian, Japanese and Chinese. In 1983 Antonio was awarded the highest academic title of 'Doctor of the Physical-Mathematical Sciences' by the

    In this study, the potential contribution of Dixon-based MR imaging with a rapid low-resolution breath-hold sequence, which is a technique used for MR-based attenuation correction (AC) for MR/positron emission tomography (PET), was evaluated for anatomical correlation of PET-positive lesions on a 3T clinical scanner compared to low-dose CT. This technique is also used in a recently installed fully integrated whole-body MR/PET system. Thirty-five patients routinely scheduled for oncological staging underwent (18)F-fluorodeoxyglucose (FDG) PET/CT and a 2-point Dixon 3-D volumetric interpolated breath-hold examination (VIBE) T1-weighted MR sequence on the same day. Two PET data sets reconstructed using attenuation maps from low-dose CT (PET(AC_CT)) or simulated MR-based segmentation (PET(AC_MR)) were evaluated for focal PET-positive lesions. The certainty for the correlation with anatomical structures was judged in the low-dose CT and Dixon-based MRI on a 4-point scale (0-3). In addition, the standardized uptake values (SUVs) for PET(AC_CT) and PET(AC_MR) were compared. Statistically, no significant difference could be found concerning anatomical localization for all 81 PET-positive lesions in low-dose CT compared to Dixon-based MR (mean 2.51 ± 0.85 and 2.37 ± 0.87, respectively; p = 0.1909). CT tended to be superior for small lymph nodes, bone metastases and pulmonary nodules, while Dixon-based MR proved advantageous for soft tissue pathologies like head/neck tumours and liver metastases. For the PET(AC_CT)- and PET(AC_MR)-based SUVs (mean 6.36 ± 4.47 and 6.31 ± 4.52, respectively) a nearly complete concordance with a highly significant correlation was found (r = 0.9975, p < 0.0001). Dixon-based MR imaging for MR AC allows for anatomical allocation of PET-positive lesions similar to low-dose CT in conventional PET/CT. Thus, this approach appears to be useful for future MR/PET for body regions not fully covered by diagnostic MRI due to potential time constraints.

    Rehabilitation efforts for the destruction of Typhoon Haiyan which ravaged the central part of the Philippines may take up to 10 years and will cost PhP 250 billion (USD 5.7 billion). To prevent extensive damages and extreme cost for rehabilitation, thorough risk assessment along with systematic infrastructure plans, evacuation plans, and land use planning of the areas must be done. The study conducted a qualitative risk assessment for the city of Tacloban, one of the severely affected areas by the storm surges brought about by the typhoon. Its coastal areas are at high risk to storm surge due to: its location relative to the typhoon track; low elevation topography; dense population; and progressive economic activities. The risk assessment model proposed by the United Nations (1991) was used, where the risk index is defined by the hazard index multiplied by its vulnerability index. The risk index was evaluated into a five-point scale: very high, high, medium, low, very low. The storm surge hazard index of the study area was derived from the simulation results of Typhoon Haiyan event using MIKE 21 - a versatile software used for coastal modelling. Simulations were made using the coupled approach of Hydrodynamic Flexible Mesh (HD FM) and Spectral Wave (SW) models. This approach takes into account both surge water levels and wave crest heights for overtopping of coastal structures. The vulnerability index was determined from population, built environment, and critical service centers. The resulting risk index map will be beneficial to the on-going rehabilitation efforts in the study area.

    Presurgical assessment of fatty degeneration is important in the management of patients with rotator cuff tears. The Goutallier classification is widely accepted as a qualitative scoring system, although it is highly observer-dependent and has poor reproducibility. The objective of this study was to quantify fatty degeneration of the supraspinatus muscle using a 2-point Dixon technique in patients with rotator cuff tears by multiple readers, and to evaluate the reproducibility compared to Goutallier classification. Two hundred patients with rotator cuff tears who underwent magnetic resonance imaging (MRI), including 2-point Dixon sequence at 3.0-T, were selected retrospectively. Qualitative and quantitative analyses of fatty degeneration were performed by two radiologists and three orthopedic surgeons independently. The fat quantification was performed by measuring signal intensity values of in phase (S(In)) and fat image (S(Fat)), and calculating fat fraction as S(Fat)/S(In). The reproducibility of MR quantification was analyzed by the intra- and interclass correlation coefficients and Bland-Altman plots. The interobserver agreement of the Goutallier classification among five readers was moderate (k = 0.51), whereas the interclass correlation coefficient regarding fat fraction value quantified in 2-point Dixon sequence was excellent (0.893). The mean differences in fat fraction values from the individual segmentation results were from -0.072 to 0.081. Proposed fat fraction grading and Goutallier grading showed similar frequency and distribution in severity of rotator cuff tears. Fat quantification in the rotator cuff muscles using a 2-point Dixon technique at 3.0-T MRI is highly reproducible and clinically feasible in comparison to the qualitative evaluation using Goutallier classification.

    To quantify the muscle fat-content (MFC) in phantoms, volunteers and patients with achillodynia using two-point Dixon-based magnetic resonance imaging (2pt-MRIDIXON) in comparison to MR spectroscopy (MRS) and visual assessment of MFC. Two-point Dixon-based MRI was used to measure the MFC of 15 phantoms containing 0-100 % fat-content and calf muscles in 30 patients (13 women; 57 ± 15 years) with achillodynia and in 20 volunteers (10 women; 30 ± 14 years) at 1.5 T. The accuracy of 2pt-MRIDIXON in quantification of MFC was assessed in vitro using phantoms and in vivo using MRS as the standard of reference. Fat-fractions derived from 2pt-MRIDIXON (FFDIXON) and MRS (FFMRS) were related to visual assessment of MFC (Goutallier grades 0-4) and Achilles-tendon quality (grade 0-4). Excellent linear correlation was demonstrated for FFDIXON with phantoms and with FFMRS in patients (p c = 0.997/0.995; p visual-grading showed no difference between both groups (p > 0.05). FFMRS and FFDIXON were significantly higher in subjects with (>grade 1) structural damage of the Achilles-tendon (p = 0.01). Two-point Dixon-based MRI allows for accurate quantification of MFC, outperforming visual assessment of calf muscle fat. Structural damage of the Achilles tendon is associated with a significantly higher MFC. Two-point Dixon-based MRI allows accurate quantification of muscular fat content (MFC). Quantitative analysis outperforms visual analysis in the detection of elevated MFC. Achillodynia results in an increased MFC of the gastrocnemius muscles. Structural damage of the Achilles tendon further increases the MFC.

    2017-02-01

    Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS) together have become the gold standard in the precise quantification of body fat. The study of the quantification of fat in the human body has matured in recent years from a simplistic interest in the whole-body fat content to detailing regional fat distributions. The realization that body-fat, or adipose tissue (AT) is far from being a mere aggregate mass or deposit but a biologically active organ in and of itself, may play a role in the association between obesity and the various pathologies that are the biggest health issues of our time. Furthermore, a major bottleneck in most medical image assessments of adipose tissue content and distribution is the lack of automated image analysis. This motivated us to develop a proper and at least partially automated methodology to accurately and reproducibly determine both body fat content and distribution in the human body, which is to be applied to cross-sectional and longitudinal studies. The AT considered here is located beneath the skin (subcutaneous) as well as around the internal organs and between muscles (visceral and inter-muscular). There are also special fat depots on and around the heart (pericardial) as well as around the aorta (peri-aortic). Our methods focus on measuring and classifying these various AT deposits in the human body in an intervention study that involves the acquisition of thoracic and abdominal MR images via a Dixon technique.

  8. Method of B0 mapping with magnitude-based correction for bipolar two-point Dixon cardiac MRI.

    Liu, Junmin; Peters, Dana C; Drangova, Maria

    2017-11-01

    The conventional two-point (2pt) Dixon technique explicitly estimates B0 map by performing phase unwrapping. When signal loss, phase singularity, artifacts, or spatially isolated regions corrupt the measured phase images, this unwrapping-based technique will face difficulty. This work aims to improve the reliability of B0 mapping by performing unwrapping error correction. To detect the unwrapping-caused phase errors, we determined a magnitude-based fat/water mask and used it as reference to identify pixels being mismatched by the phase-based mask, which was derived from the B0-corrected phase term of the Hermitian product between echoes. Then, we corrected the afore-determined phase error on a region-by-region basis. We tested the developed method with nine patients' data, and the results were compared with a well-established region-growing technique. By adding the step to correct unwrapping-caused error, we improved the robustness of B0 mapping, resulting in better fat-water separation when compared with the conventional 2pt and the phasor-based region-growing techniques. We showed the feasibility of B0 mapping with bipolar 2pt human cardiac data. The software is freely available to the scientific community.

    2013-10-01

    A novel 3D breath-held Dixon fat-water separated balanced steady state free precession (b-SSFP) sequence for MR cholangiopancreatography (MRCP) is described and its potential clinical utility assessed in a series of patients. The main motivation is to develop a robust breath-held alternative to the respiratory gated 3D Fast Spin Echo (FSE) sequence, the current clinical sequence of choice for MRCP. Respiratory gated acquisitions are susceptible to motion artifacts and blurring in patients with significant diaphragmatic drift, erratic respiratory rhythms or sleep apnea. A two point Dixon fat-water separation scheme was developed which eliminates signal loss arising from B0 inhomogeneity effects and minimizes artifacts from perturbation of the b-SSFP steady state. Preliminary results from qualitative analysis of 49 patients demonstrate robust performance of the 3D Dixon b-SSFP sequence with diagnostic image quality acquired in a 20-24s breath-hold.

    2014-10-31

    To establish a dedicated protocol for the three-dimensional (3D) quantification of plaque lipids in apolipoprotein E-deficient (apoE{sup -/-}) mice using ex vivo MRI. ApoE{sup -/-} mice were fed a high-fat diet (n = 10) or normal food (n = 10) for 3 months. Subsequently, a 3D FLASH MRI sequence was used to view the anatomy of the aortic root in the isolated hearts, where a 3D double-echo two-excitation pulse sequence (DIXON sequence) was used to selectively image plaque lipids. The vessel wall, lumen and plaque lipid volumes were quantified by MRI and histology for correlation analysis. DIXON MRI allowed visualisation and accurate quantification of plaque lipids. When comparing the vessel wall, lumen and plaque lipid sizes in the aortic root, Bland-Altman and linear regression analysis revealed a close correlation between MRI results and the histological data both on a slice-by-slice basis and of the volumetric measurements (vessel wall: r{sup 2} = 0.775, p < 0.001; vessel lumen: r{sup 2} = 0.875; p = 0.002; plaque lipid: r{sup 2} = 0.819, p = 0.003). The combination of 3D FLASH and DIXON-sequence MRI permits an accurate ex vivo assessment of the investigated plaque parameters in the aortic root of mice, particularly the lipid content. (orig.)

    Purpose: MR-based pseudo-CT has an important role in MR-based radiation therapy planning and PET attenuation correction. The purpose of this study is to establish a clinically feasible approach, including image acquisition, correction, and CT formation, for pseudo-CT generation of the brain using a single-acquisition, undersampled ultrashort echo time (UTE)-mDixon pulse sequence. Methods: Nine patients were recruited for this study. For each patient, a 190-s, undersampled, single acquisition UTE-mDixon sequence of the brain was acquired (TE = 0.1, 1.5, and 2.8 ms). A novel method of retrospective trajectory correction of the free induction decay (FID) signal was performed based on point-spread functions of three external MR markers. Two-point Dixon images were reconstructed using the first and second echo data (TE = 1.5 and 2.8 ms). R2{sup ∗} images (1/T2{sup ∗}) were then estimated and were used to provide bone information. Three image features, i.e., Dixon-fat, Dixon-water, and R2{sup ∗}, were used for unsupervised clustering. Five tissue clusters, i.e., air, brain, fat, fluid, and bone, were estimated using the fuzzy c-means (FCM) algorithm. A two-step, automatic tissue-assignment approach was proposed and designed according to the prior information of the given feature space. Pseudo-CTs were generated by a voxelwise linear combination of the membership functions of the FCM. A low-dose CT was acquired for each patient and was used as the gold standard for comparison. Results: The contrast and sharpness of the FID images were improved after trajectory correction was applied. The mean of the estimated trajectory delay was 0.774 μs (max: 1.350 μs; min: 0.180 μs). The FCM-estimated centroids of different tissue types showed a distinguishable pattern for different tissues, and significant differences were found between the centroid locations of different tissue types. Pseudo-CT can provide additional skull detail and has low bias and absolute error of

    This study aimed to evaluate (1) the agreement between the true fat fraction (FF) and proton density FF (PDFF) measured using a six-echo modified Dixon (6mDixon) and magnetic resonance spectroscopy (MRS) and (2) the influence of fat on T2* values. The study was performed using phantoms of varying fat and iron content. Point-resolved spectroscopy (PRESS) and stimulated echo acquisition mode (STEAM) with single-echo (S) and multiecho (M) (PRESS-S, PRESS-M, STEAM-S, and STEAM-M) were used for MRS. In phantoms without iron, the agreement between the true FF and measured PDFF was tested using Bland-Altman analysis. The influence of iron on PDFF was evaluated in phantoms with iron. The relationship between the true FF and T2* value was assessed in phantoms without iron, wherein the mean differences (limits of agreement) for each method were as follows: 6mDixon 2.9% (-2.4 to 8.1%); STEAM-S 3.2% (-9.5 to 16.0%); STEAM-M -0.7% (-6.9 to 5.5%); PRESS-S 8.9% (-14.5 to 32.4%); and PRESS-M -5.8% (-18.3 to 6.7%). In the 20% fat phantoms with iron, as iron increased, PDFFs with STEAM-S, PRESS-S, and PRESS-M were considerably overestimated, while, PDFF with STEAM-M was stable at 0.04-0.2 mM iron concentrations (17.2 and 21.4%, respectively), and PDFF with 6mDixon was reliable at even 0.4 mM iron concentration (24.8%). The T2* value showed a negative correlation with the true FF (r = -0.942, P = 0.005). STEAM-M and 6mDixon were reliable methods of fat quantification in the absence of iron, and the T2* value was shortened by fat.

    He is a brilliant math Professor with a peculiar problem—ever since a traumatic head injury, he has lived with only eighty minutes of short-term memory. She is an astute young Housekeeper—with a ten-year-old son—who is hired to care for the Professor. And every morning, as the Professor and the Housekeeper are introduced to each other anew, a strange and beautiful relationship blossoms between them. Though he cannot hold memories for long (his brain is like a tape that begins to erase itself every eighty minutes), the Professor's mind is still alive with elegant equations from the past. And the numbers, in all of their articulate order, reveal a sheltering and poetic world to both the Housekeeper and her young son. The Professor is capable of discovering connections between the simplest of quantities—like the Housekeeper's shoe size—and the universe at large, drawing their lives ever closer and more profoundly together, even as his memory slips away.

    The ability to apply an ecosystem approach to the Strymonas River catchment was investigated using the MIKE 11 modeling system for the simulation of surface water. The Strymonas River catchment is shared mainly between Bulgaria and Greece. The river feeds the artificial Lake Kerkini, a significant wetland ecosystem, and further downstream it outflows to the Gulf of Strymonikos, whose estuary ecosystem is very important for fisheries, biodiversity and tourism. MIKE 11-NAM was used for the simulation of rainfall-runoff process in the Strymonas River catchment and MIKE 11-HD was used to simulate the unsteady flow of the Strymonas River and to apply management rules based on the water level of Lake Kerkini. Two water level management scenarios were investigated. The first scenario referred to the mean daily-observed water level of Lake Kerkini between 1986 and 2006, and the second scenario represented adjustments necessary to fulfill the lake's ecosystem requirements. Under the current water level management practices (Scenario 1), the Strymonas River-Lake Kerkini system has enough water to fulfill its Irrigation Water Requirements (IWR) in normal and wet years while a slight deficit is appeared in dry years; however, both Lake Kerkini and the Strymonas River estuary ecosystems are subject to pressures, since reduction of the forest area has been recorded. Applying the ecosystem approach (Scenario 2), the protection of the riparian forest of Lake Kerkini is achieved while in normal and wet years the IWR are fulfilled and the deficit of the IWR is increased in dry years. Compared to Scenario 1, the pressure of the Strymonas River estuary ecosystem is slightly increased. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Northeastern British Columbia (BC) is undergoing rapid development for oil and gas extraction, largely depending on subsurface hydraulic fracturing (fracking), which relies on available freshwater. Even though this industrial activity has made substantial contributions to regional and provincial economies, it is important to ensure that sufficient and sustainable water supplies are available for all those dependent on the resource, including ecological systems. Further, BC statistics predict that the northeastern region's population will increase by 30% over the next 25 years, thereby amplifying the demands of domestic and industrial water usage. Hence, given the increasing demands for surface water in the complex wetlands of northeastern BC, obtaining accurate long-term water balance information is of vital importance. Thus, this study aims to simulate the 1979-2014 water balance at two boreal watersheds using the MIKE SHE model. More specifically, this research intends to quantify the historical, and regional, water budgets and their associated hydrological processes at two boreal watersheds—the Coles Lake and Tsea Lake watersheds—in northeastern BC. The development of coupled groundwater and surface water model of these watersheds are discussed. The model setup, calibration process, and results are presented, focusing on the water balance of boreal watersheds. Hydrological components within these watersheds are quantified through a combination of intensive fieldwork, observational data, analysis and numerical modeling. The output from the model provides important information for decision makers to manage water resources in northeastern BC. Keywords: Northeastern BC; boreal watershed; water balance; MIKE SHE hydrological model.

  14. Professor Attitudes and Beliefs about Teaching Evolution

    Science.gov (United States)

    Barnes, Maryann Elizabeth

    Teaching evolution has been shown to be a challenge for faculty, in both K-12 and postsecondary education. Many of these challenges stem from perceived conflicts not only between religion and evolution, but also faculty beliefs about religion, it's compatibility with evolutionary theory, and it's proper role in classroom curriculum. Studies suggest that if educators engage with students' religious beliefs and identity, this may help students have positive attitudes towards evolution. The aim of this study was to reveal attitudes and beliefs professors have about addressing religion and providing religious scientist role models to students when teaching evolution. 15 semi-structured interviews of tenured biology professors were conducted at a large Midwestern universiy regarding their beliefs, experiences, and strategies teaching evolution and particularly, their willingness to address religion in a class section on evolution. Following a qualitative analysis of transcripts, professors did not agree on whether or not it is their job to help students accept evolution (although the majority said it is not), nor did they agree on a definition of "acceptance of evolution". Professors are willing to engage in students' religious beliefs, if this would help their students accept evolution. Finally, professors perceived many challenges to engaging students' religious beliefs in a science classroom such as the appropriateness of the material for a science class, large class sizes, and time constraints. Given the results of this study, the author concludes that instructors must come to a consensus about their goals as biology educators as well as what "acceptance of evolution" means, before they can realistically apply the engagement of student's religious beliefs and identity as an educational strategy.

    Hybrid positron emission tomography and magnetic resonance (PET/MR) imaging performs a two-point Dixon MR sequence for attenuation correction. However, MR data in hybrid PET/MR should provide anatomic and morphologic information as well as an attenuation map. We evaluated the Dixon sequence of hybrid PET/MR for anatomic correlation of PET-positive lesions compared with contrast-enhanced PET/computed tomography (CT) in patients with oncologic diseases. Twelve patients underwent a single injection, dual imaging protocol. PET/CT was performed with an intravenous contrast agent (85±13 min after {sup 18}F-FDG injection of 403± 45 MBq) and then (125±19 min after injection) PET/MR was performed. Attenuation correction and anatomic allocation of PET were performed using contrast-enhanced CT for PET/CT and Dixon MR sequence for hybrid PET/MR. The Dixon MR sequence and contrast-enhanced CT were compared for anatomic correlation of PET-positive lesions (scoring scale ranging from 0 to 3 for visual ratings). Additionally, standardized uptake values (SUVs) for the detected lesions were assessed for quantitative comparison. Both hybrid PET/MR and contrast-enhanced PET/CT identified 55 lesions with increased FDG uptake in ten patients. In total, 28 lymph nodes, 11 bone lesions, 3 dermal nodules, 3 pleural thickening lesions, 2 thyroid nodules, 1 pancreas, 1 liver, 1 ovary, 1 uterus, 1 breast, 1 soft tissue and 2 lung lesions were present. The best performance was observed for anatomic correlation of PET findings by the contrast-enhanced CT scans (contrast-enhanced CT, 2.64± 0.70; in-phase, 1.29±1.01; opposed-phase, 1.29±1.15; water-weighted, 1.71±1.07; fat weighted, 0.56±1.03). A significant difference was observed between the scores obtained from the contrast-enhanced CT and all four coregistered Dixon MR images. Quantitative evaluation revealed a high correlation between the SUVs measured with hybrid PET/MR (SUVmean, 2.63±1.62; SUVmax, 4.30±2.88) and contrast

    To investigate three-echo T2*-corrected Dixon magnetic resonance imaging (MRI) for noninvasively estimating hepatic fat content (HFC) compared with biopsy. One hundred patients (50 men, 50 women; mean age, 57.7±14.2 years) underwent clinically indicated liver core biopsy (102 valid tissue samples) and liver MRI 24 to 72 hours later. MRI was performed at 1.5T (Magnetom Avanto, Siemens Healthcare, Erlangen, Germany) using Dixon imaging with T2* correction (work in progress, WIP-432.rev.1, Siemens Healthcare). An ultrafast breath-hold three-echo 3D-gradient echo sequence with TR/TE1/TE2/TE3 of 11/2.4/4.8/9.6 milliseconds, and online calculation of T2*-corrected water images (signal intensities of water [SIW]), fat images (SIF), and fat content map (SIFAT=10×SIF/(SIW+SIF)) was used. SIs of the calculated fat content map (SIFAT) were verified using the histologically quantified HFC (HFC(path)). Spearman correlation for HFC(path) and SIFAT was calculated. Stage of fibrosis, hepatic iron content, and patterns of liver fat (macrovesicular, microvesicular, mixed) and their influence on predicting HFC by MRI were determined. Correlation between SIFAT and HFC(path) was rspearman=0.89. Agreement between HFC predicted by MRI and HFC(path) calculated by nonlinear saturation-growth regression was rspearman=0.89. Kruskal-Wallis analysis revealed no significant difference for SIFAT across fibrosis grades (P=0.90) and liver iron content (P=0.76). Regarding the cellular architecture of liver fat, the microvesicular pattern showed lower mean ranks in SI than macrovesicular and mixed patterns (P=0.01). T2*-corrected Dixon MRI is a noninvasive tool for estimating HFC, showing excellent correlation with liver biopsy without being limited by liver iron content and fibrosis/cirrhosis.

    To evaluate the influence of Gadolinium contrast agent on image segmentation in magnetic resonance (MR)-based attenuation correction (AC) with four-segment dual-echo time Dixon-sequences in whole-body [18F]-fluorodeoxyglucose positron emission tomography (PET)/MR imaging, and to analyze the consecutive effect on standardized uptake value (SUV). Hybrid imaging with an integrated PET/MR system was performed in 30 oncological patients. AC was based on MR imaging with a Dixon sequence with subsequent automated image segmentation. AC maps (µmaps) were acquired and reconstructed prior to (µmap-gd) and after (µmap+gd) Gd-contrast agent application. For quantification purposes, the SUV of organs and tumors based on both µmaps were compared. Tissue classification based on µmap-gd was correct in 29/30 patients; based on µmap+gd, the brain was falsely classified as fat in 12/30 patients with significant underestimation of SUV. In all cancerous lesions, tissue segmentation was correct. All concordant µmaps-gd/+gd resulted in no significant difference in SUV. In PET/MR, Gd-contrast agent potentially influences fat/water separation in Dixon-sequences of the head with above-average false tissue segmentation and an associated underestimation of SUV. Thus, MR-based AC should be acquired prior to Gd-contrast agent application. Additionally, integrating the MR-based AC maps into the reading-routine in PET/MR is recommended to avoid interpretation errors in cases where tissue segmentation fails.

    Fatty liver and non-alcoholic steatohepatitis are frequently associated with obesity. Weight loss is the mainstay of therapy for these conditions. In this case report, we used a modification of the Dixon method to demonstrate normalization of hepatic fat content in an obese individual with fatty liver following weight reduction. This technique involves fast gradient echo instead of spin echo, which has been utilized previously, as the former provides an accurate and more rapid means of assessing hepatic fat content. This technique is recommended for the assessment of hepatic steatosis in at-risk subjects. (orig.)

    The aim of this study was to assess the reproducibility of standard, Dixon-based attenuation correction (MR-AC) in PET/MR imaging. A further aim was to estimate a patient-specific lean body mass (LBM) from these MR-AC data. Ten subjects were positioned in a fully integrated PET/MR system, and 3 consecutive multibed acquisitions of the standard MR-AC image data were acquired. For each subject and MR-AC map, the following compartmental volumes were calculated: total body, soft tissue (ST), fat, lung, and intermediate tissue (IT). Intrasubject differences in the total body and subcompartmental volumes (ST, fat, lung, and IT) were assessed by means of coefficients of variation (CVs) calculated across the 3 consecutive measurements and, again, across these measurements but excluding those affected by major artifacts. All subjects underwent a body composition measurement using air displacement plethysmography (ADP) that was used to calculate a reference LBMADP A second LBM estimate was derived from available MR-AC data using a formula incorporating the respective tissue volumes and densities as well as the subject-specific body weights. A third LBM estimate was obtained from a sex-specific formula (LBMFormula). Pearson correlation was calculated for LBMADP, LBMMR-AC, and LBMFormula Further, linear regression analysis was performed on LBMMR-AC and LBMADP. The mean CV for all 30 scans was 2.1 ± 1.9% (TB). When missing tissue artifacts were excluded, the CV was reduced to 0.3 ± 0.2%. The mean CVs for the subcompartments before and after exclusion of artifacts were 0.9 ± 1.1% and 0.7 ± 0.7% for the ST, 2.9 ± 4.1% and 1.3 ± 1.0% for fat, and 3.6 ± 3.9% and 1.3 ± 0.7% for the IT, respectively. Correlation was highest for LBMMR-AC and LBMADP (r = 0.99). Linear regression of data excluding artifacts resulted in a scaling factor of 1.06 for LBMMR-AC CONCLUSION: LBMMR-AC is shown to correlate well with standard LBM measurements and thus offers routine LBM-based SUV

    In the absence of CT or traditional transmission sources in combined clinical positron emission tomography/magnetic resonance (PET/MR) systems, MR images are used for MR-based attenuation correction (MR-AC). The susceptibility effects due to metal implants challenge MR-AC in the neck region of patients with dental implants. The purpose of this study was to assess the frequency and magnitude of subsequent PET image distortions following MR-AC. A total of 148 PET/MR patients with clear visual signal voids on the attenuation map in the dental region were included in this study. Patients were injected with [{sup 18}F]-FDG, [{sup 11}C]-PiB, [{sup 18}F]-FET, or [{sup 64}Cu]-DOTATATE. The PET/MR data were acquired over a single-bed position of 25.8 cm covering the head and neck. MR-AC was based on either standard MR-AC{sub DIXON} or MR-AC{sub INPAINTED} where the susceptibility-induced signal voids were substituted with soft tissue information. Our inpainting algorithm delineates the outer contour of signal voids breaching the anatomical volume using the non-attenuation-corrected PET image and classifies the inner air regions based on an aligned template of likely dental artifact areas. The reconstructed PET images were evaluated visually and quantitatively using regions of interests in reference regions. The volume of the artifacts and the computed relative differences in mean and max standardized uptake value (SUV) between the two PET images are reported. The MR-based volume of the susceptibility-induced signal voids on the MR-AC attenuation maps was between 1.6 and 520.8 mL. The corresponding/resulting bias of the reconstructed tracer distribution was localized mainly in the area of the signal void. The mean and maximum SUVs averaged across all patients increased after inpainting by 52% (± 11%) and 28% (± 11%), respectively, in the corrected region. SUV underestimation decreased with the distance to the signal void and correlated with the volume of the susceptibility

    Full Text Available Paolo Talamucci, Full Professor of Range Management at the Università degli Studi in Florence from 1975 to 2001, passed away on 27th November 2009, after a brief and unrelenting illness. Professor Talamucci spent many long years in the field of research, in both Mediterranean and Alpine regions. His research, profoundly rooted in the territory he was studying, holistic in its approach and rigorously scientific, was characterized by a strong interdisciplinary element, seeking always to take into account the totality of the components of the ecosystem. Professor Talamucci was one of the first scholars of the pastoral system to highlight the problems related to the abandonment of traditional animal husbandry in mountainous zones and to look for ways to counteract the undesirable transformation of the landscape and the consequent loss of biodiversity. His curriculum and his numerous scientific publications bear testimony not only to the prestigious research institutes, world-wide, with which he was associated, but also to the important international dimension of his research.

    To evaluate the automated two-point Dixon screening sequence for the detection and estimated quantification of hepatic iron and fat compared with standard sequences as a reference. One hundred and two patients with suspected diffuse liver disease were included in this prospective study. The following MRI protocol was used: 3D-T1-weighted opposed- and in-phase gradient echo with two-point Dixon reconstruction and dual-ratio signal discrimination algorithm (''screening'' sequence); fat-saturated, multi-gradient-echo sequence with 12 echoes; gradient-echo T1 FLASH opposed- and in-phase. Bland-Altman plots were generated and correlation coefficients were calculated to compare the sequences. The screening sequence diagnosed fat in 33, iron in 35 and a combination of both in 4 patients. Correlation between R2* values of the screening sequence and the standard relaxometry was excellent (r = 0.988). A slightly lower correlation (r = 0.978) was found between the fat fraction of the screening sequence and the standard sequence. Bland-Altman revealed systematically lower R2* values obtained from the screening sequence and higher fat fraction values obtained with the standard sequence with a rather high variability in agreement. The screening sequence is a promising method with fast diagnosis of the predominant liver disease. It is capable of estimating the amount of hepatic fat and iron comparable to standard methods.

  19. MRI-based attenuation correction for hybrid PET/MRI systems: a 4-class tissue segmentation technique using a combined ultrashort-echo-time/Dixon MRI sequence.

    Accurate γ-photon attenuation correction (AC) is essential for quantitative PET/MRI as there is no simple relation between MR image intensity and attenuation coefficients. Attenuation maps (μ-maps) can be derived by segmenting MR images and assigning attenuation coefficients to the compartments. Ultrashort-echo-time (UTE) sequences have been used to separate cortical bone and air, and the Dixon technique has enabled differentiation between soft and adipose tissues. Unfortunately, sequential application of these sequences is time-consuming and complicates image registration. A UTE triple-echo (UTILE) MRI sequence is proposed, combining UTE sampling for bone detection and gradient echoes for Dixon water-fat separation in a radial 3-dimensional acquisition (repetition time, 4.1 ms; echo times, 0.09/1.09/2.09 ms; field strength, 3 T). Air masks are derived mainly from the phase information of the first echo; cortical bone is segmented using a dual-echo technique. Soft-tissue and adipose-tissue decomposition is achieved using a 3-point Dixon-like decomposition. Predefined linear attenuation coefficients are assigned to classified voxels to generate MRI-based μ-maps. The results of 6 patients are obtained by comparing μ-maps, reciprocal sensitivity maps, reconstructed PET images, and brain region PET activities based on either CT AC, two 3-class MRI AC techniques, or the proposed 4-class UTILE AC. Using the UTILE MRI sequence, an acquisition time of 214 s was achieved for the head-and-neck region with 1.75-mm isotropic resolution, compared with 164 s for a single-echo UTE scan. MRI-based reciprocal sensitivity maps show a high correlation with those derived from CT scans (R(2) = 0.9920). The same is true for PET activities (R(2) = 0.9958). An overall voxel classification accuracy (compared with CT) of 81.1% was reached. Bone segmentation is inaccurate in complex regions such as the paranasal sinuses, but brain region activities in 48 regions across 6 patients show a

    Full Text Available Entendendo que a indiferença na ação pedagógica contribui para a reprodução das desigualdades no sistema de ensino, o presente artigo busca captar, a partir de entrevistas semiestruturadas, traços do habitus de professores supervisores de disciplinas do curso de Licenciatura em Pedagogia na modalidade a distância na Universidade de Brasília - UnB no âmbito do Sistema Universidade Aberta do Brasil - UAB. As orientações metodológicas de Bourdieu (2007 foram um dos elementos orientadores na análise das entrevistas, considerando ainda o uso heurístico do conceito de habitus. Conclui-se que o habitus professoral envolve esforços voluntários em busca de uma ação pedagógica diferenciada. No entanto, ele é ambíguo e condescendente frente aos limites do modelo de EaD no âmbito da UAB. Ao fim, os dados analisados permitem fornecer elementos para reorientação político-pedagógica que vise a um novo modelo de EaD nacional.

  3. When Professors Don't Return Essays.

    Feldman, William; Dhaliwal, Gurpreet

    2015-01-01

    Students devote hundreds of hours to writing notes during medical school clerkships but receive very limited feedback on that work. Medical student notes are like college essays-both are persuasive compositions. But attending physicians rarely scrutinize student notes like college professors analyze essays. This is a missed opportunity to teach clinical reasoning. A survey at our institution showed that only 16% of students received written feedback and 31% received oral feedback on their notes from more than 3 attending physicians during the first 8 months of 3rd-year clerkships. Many studies have reported a paucity of feedback across multiple domains and a sense among students that clinical reasoning is not being adequately taught during clerkships. Meanwhile, college professors teach written composition and reasoning through interactive methods that help students to develop structured, well-reasoned arguments. A recent study showed that 85% of Oxford undergraduates favored these demanding and time-intensive tutorials. Attending physicians who adopt a tutorial-based approach toward their students' notes would have a forum to teach clinical reasoning and emphasize the importance of written composition in medical practice.

    The purpose of the study was to evaluate signal-fat-fraction (SFF) analysis based on a 2-point-Dixon water-fat separation method in whole-body simultaneous PET/MR imaging for identifying brown adipose tissue (BAT) and discriminating it from white adipose tissue (WAT) using cross-validation via PET. This retrospective, internal review board-approved study evaluated 66 PET/MR imaging examinations of 33 pediatric patients (mean age, 14.7 y; range, 7.4-21.4 y). Eleven elderly patients were evaluated as controls (mean age, 79.9 y; range, 76.3-88.6 y). Pediatric patients were divided into 2 groups: with and without metabolically active supraclavicular BAT. The standard of reference for the presence of BAT was at least 1 PET examination showing (18)F-FDG uptake. PET/MR imaging included a 2-point Dixon water-fat separation method. Signal intensities in regions of interest on fat and water images and mean standardized uptake values (SUVmean) were determined bilaterally in supraclavicular and gluteal fat depots. SFF was calculated from the ratio of fat signal over summed water and fat signal. Statistical analysis was conducted using the Student t test and correlation analysis. SFF was significantly lower (P analysis is a reproducible imaging modality for the detection of human BAT and discrimination from WAT. SFF values of BAT are independent from its metabolic activity, making SFF a more reliable parameter for BAT than the commonly used PET signal. However, with the intent to investigate both the composition of BAT and its activation status, hybrid PET/MR imaging might provide supplemental information. © 2015 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    2014-12-01

    Full Text Available Connecting back with an already well-established tradition of scholarly explorations of images of Romanianness, as emerging from (nonfictional representations of cross-cultural, Anglo-Romanian encounters, the present paper focuses on one of the most recent textual productions foregrounding an English traveller’s gaze on his Romanian hosts, namely Mike Ormsby’s collection of short stories Never Mind the Balkans, Here’s Romania (2008. Applying an imagological grid to it, the paper aims at providing evidence in defence of the idea that, at least after 1989, the English observers’ attitudes towards and, implicitly, textual mirroring of Romania have undergone significant changes. In doing that, it reflects upon the ‘game’ of auto- and hetero-images at the heart of the narrative discourse as meant to point to both an awareness of cultural differences and the need to overcome cultural biases in one’s mind with a view to successful intercultural communication in the context of globalisation-driven societal transformations.

    Full Text Available Academics who hold positions at single-mode, distance education institutions are presently being hampered by an adherence to a long-standing set of protocols (specific office location, face-to-face meetings that were put in place when the conventional post-secondary was the norm. With the advent of a powerful merging of personal computers and the internet, a shift from those protocols to one of support for the virtual professor is in the offing, to the benefit of both the professoriate and the student. A key factor in this shift is the degree and quality of institutional support that will allow these changes to take place. This paper focuses on a number of the key factors that will have to be addressed if this new type of distance education academic is to function effectively.

  5. Multi-site calibration, validation, and sensitivity analysis of the MIKE SHE Model for a large watershed in northern China

    Full Text Available Model calibration is essential for hydrologic modeling of large watersheds in a heterogeneous mountain environment. Little guidance is available for model calibration protocols for distributed models that aim at capturing the spatial variability of hydrologic processes. This study used the physically-based distributed hydrologic model, MIKE SHE, to contrast a lumped calibration protocol that used streamflow measured at one single watershed outlet to a multi-site calibration method which employed streamflow measurements at three stations within the large Chaohe River basin in northern China. Simulation results showed that the single-site calibrated model was able to sufficiently simulate the hydrographs for two of the three stations (Nash-Sutcliffe coefficient of 0.65–0.75, and correlation coefficient 0.81–0.87 during the testing period, but the model performed poorly for the third station (Nash-Sutcliffe coefficient only 0.44. Sensitivity analysis suggested that streamflow of upstream area of the watershed was dominated by slow groundwater, whilst streamflow of middle- and down- stream areas by relatively quick interflow. Therefore, a multi-site calibration protocol was deemed necessary. Due to the potential errors and uncertainties with respect to the representation of spatial variability, performance measures from the multi-site calibration protocol slightly decreased for two of the three stations, whereas it was improved greatly for the third station. We concluded that multi-site calibration protocol reached a compromise in term of model performance for the three stations, reasonably representing the hydrographs of all three stations with Nash-Sutcliffe coefficient ranging from 0.59–072. The multi-site calibration protocol applied in the analysis generally has advantages to the single site calibration protocol.

    2005-11-01

    It is with great sadness that we report the death of Jan Evetts, who lost his second battle with cancer on 18 August 2005. In 1988 he was appointed Founding Editor of this journal where his leadership created the foundation upon which its success rests today. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials, and was an indefatigable champion of the development of applications of superconductivity. The loss to the scientific community is incalculable, as is attested by the many communications received from colleagues throughout the world. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' embryonic superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for applications in magnets. Competing theories for the critical current density at that time were fine filaments or `Mendelssohn Sponge' versus the pinning of Abrikosov quantized vortices. The results of the group's work, to which Jan made a major contribution, came down heavily in favour of the latter theory. Jan's outstanding characteristic was his

  7. Direct PseudoCT Generation for Pelvis PET/MRI Attenuation Correction using Deep Convolutional Neural Networks with Multi-parametric MRI: Zero Echo-time and Dixon Deep pseudoCT (ZeDD-CT).

    Accurate quantification of positron emission tomography (PET) uptake depends on accurate attenuation correction in reconstruction. Current magnetic resonance-based attenuation correction methods (MRAC) for body PET imaging use a fat/water map derived from a two-echo Dixon magnetic resonance imaging (MRI) sequence, where bone is neglected. Ultrashort echo-time and zero echo-time (ZTE) pulse sequences can capture bone information. We propose the use of patient-specific multi-parametric MRI consisting of Dixon MRI and proton-density-weighted ZTE MRI to directly synthesize pseudoCT images with the use of a deep learning model: we name this method Zero echo-time and Dixon Deep pseudoCT (ZeDD-CT). Methods: Twenty-six patients were scanned using an integrated 3 Tesla time-of-flight PET/MRI system. Helical x-ray computed tomography (CT) images of the patients were acquired separately. A deep convolutional neural network was trained to transform ZTE and Dixon MRI into synthetic CT images (ZeDD-CT). Ten patients were used for model training and sixteen patients were used for evaluation. Bone and soft tissue lesions were identified and the SUVmax was measured. The root-mean-squared-error (RMSE) was used to compare the MRAC methods with the ground-truth CTAC. Results: A total of 30 bone lesions and 60 soft tissue lesions were evaluated. For bone lesions, there was a factor of 4 reduction of RMSE in PET quantification (RMSE were 10.24% for Dixon PET, and 2.68% for ZeDD PET); for soft tissue lesions, there was a factor of 1.5 reduction of RMSE (RMSE were 6.24% for Dixon PET, and 4.07% for ZeDD PET). Conclusion: The ZeDD-CT produces natural-looking and quantitatively accurate pseudoCT images and reduces error in pelvis PET/MRI attenuation correction compared to standard methods.

    To evaluate the influence of scan duration on pharmacokinetic parameters and their performance in differentiating benign from malignant breast lesions. Dynamic breast imaging was performed on a 3.0-T MR system using a prototype CAIPIRINHA-Dixon-TWISTVIBE (CDT-VIBE) sequence with a temporal resolution of 11.9 s. Enrolled in the study were 53 women with 55 lesions (26 benign and 29 malignant). Pharmacokinetic parameters (Ktrans, ve, kep and iAUC) were calculated for various scan durations from 1 to 7 min after injection of contrast medium using the Tofts model. Ktrans, kep and ve calculated from the 1-min dataset were significantly different from those calculated from the other datasets. In benign lesions, Ktrans, kep and ve were significantly different only between 1 min and 2 min (corrected P > 0.05), but in malignant lesions there were significant differences for any of the comparisons up to 6 min vs. 7 min (corrected P > 0.05). There were no significant differences in AUCs for any of the parameters (P > 0.05). In breast dynamic contrast-enhanced MRI the scan duration has a significant impact on pharmacokinetic parameters, but the diagnostic ability may not be significantly affected. A scan duration of 5 min after injection of contrast medium may be sufficient for calculation of Tofts model pharmacokinetic parameters. (orig.)

    Full Text Available Technology enabled learning is becoming more popular and pervasive in education. While the effectiveness of distance learning versus traditional classroom education is strongly debated, human factors such as students’ perception of their professors can influence their desire to learn. This research examines the perceptual effect of attractive professors on business students enrolled in distance learning courses. This study expands on prior studies by testing whether the attractiveness of the professor matters to student learning within the context of online learning environment. A total of 122 online business students were surveyed. Our findings suggest that professor’s attractiveness has a statistically significant effect on student learning, motivation, and satisfaction. In addition, online students perceived attractive professors with more expertise as an instructor. Female students had higher motivation than male students. Furthermore, separate analysis indicated that attractiveness effects were stronger for participants over the age 46 when compared to other groups.

    Full Text Available This study focuses on the qualities of Chinese university professors as perceived by their students and the effects of those qualities on student learning and motivation. Specifically, what qualities and personal characteristics do Chinese university students attribute to their favorite and least favorite professors, and how do those qualities and characteristics affect Chinese university students? Out of 280 students surveyed from three different universities, 226 surveys were completed, returned and included in the final analysis (response rate of 80.7%. The research found that Chinese students favored professors who are entertaining, who help them learn more and who provide them with helpful feedback on their assignments. Students disfavor professors who are boring, arrogant and do not provide helpful feedback or help them learn more. Linear regressions revealed a connection between high quality professors and student learning and motivation. Along with other studies, this research provides evidence that effective university professors are those who not only possess expertise in their fields, but in addition are engaging, student-focused and able to build rapport with their students.

    To evaluate and compare conventional T1-weighted 2D turbo spin echo (TSE), T1-weighted 3D volumetric interpolated breath-hold examination (VIBE), and two-point 3D Dixon-VIBE sequences for automatic segmentation of visceral adipose tissue (VAT) volume at 3 Tesla by measuring and compensating for errors arising from intensity nonuniformity (INU) and partial volume effects (PVE). The body trunks of 28 volunteers with body mass index values ranging from 18 to 41.2 kg/m2 (30.02 ± 6.63 kg/m2) were scanned at 3 Tesla using three imaging techniques. Automatic methods were applied to reduce INU and PVE and to segment VAT. The automatically segmented VAT volumes obtained from all acquisitions were then statistically and objectively evaluated against the manually segmented (reference) VAT volumes. Comparing the reference volumes with the VAT volumes automatically segmented over the uncorrected images showed that INU led to an average relative volume difference of -59.22 ± 11.59, 2.21 ± 47.04, and -43.05 ± 5.01 % for the TSE, VIBE, and Dixon images, respectively, while PVE led to average differences of -34.85 ± 19.85, -15.13 ± 11.04, and -33.79 ± 20.38 %. After signal correction, differences of -2.72 ± 6.60, 34.02 ± 36.99, and -2.23 ± 7.58 % were obtained between the reference and the automatically segmented volumes. A paired-sample two-tailed t test revealed no significant difference between the reference and automatically segmented VAT volumes of the corrected TSE (p = 0.614) and Dixon (p = 0.969) images, but showed a significant VAT overestimation using the corrected VIBE images. Under similar imaging conditions and spatial resolution, automatically segmented VAT volumes obtained from the corrected TSE and Dixon images agreed with each other and with the reference volumes. These results demonstrate the efficacy of the signal correction methods and the similar accuracy of TSE and Dixon imaging for automatic volumetry of VAT at 3 Tesla.

    Parallel imaging (PI) techniques are used for overcoming lower spatial and time resolution for magnetic resonance imaging (MRI). There is clinical need to overcome inevitable noise by decreased voxel size and signal-to-noise issue by using high-acceleration factor (AF). To determine whether the combination of a modified Dixon three-dimensional (3D) T1-weighted (T1W) gradient echo technique (mDixon-3D-GRE) and high-acceleration ([HA], AF = 5) PI can provide breath-hold (BH) T1W imaging with better image quality than conventional fat-suppressed 3D-T1W-GRE (SPAIR-3D-GRE) for Gd-EOB-DTPA-enhanced liver MR. This retrospective study was approved by our institutional review board and informed consent was waived. There were 138 patients who underwent Gd-EOB-DTPA-enhanced liver MR at 3 T using either standard SPAIR-3D-GRE sequences with an AF of 2.6 (n = 68, Standard group) or mDixon-3D-GRE with an AF of 5 (n = 70, HA group). In the HA group, hepatobiliary phase was obtained three times using HA-mDixon-3D-GRE (AF = 5), HA-SPAIR-3D-GRE (AF = 5), and standard-SPAIR-3D-GRE (AF = 2.6). Image noise, quality, and anatomic depiction of dynamic phase were compared between standard and HA groups, and those of hepatobiliary phase were compared among the three image sets in HA group. As for dynamic imaging, the HA-mDixon-3D-GRE images showed better anatomic details and overall image quality than standard-SPAIR-3D-GRE sequence (arterial phase: 3.56 ± 0.63 vs. 2.66 ± 0.69, P acceleration PI provided better quality BH-T1W imaging compared with conventional SPAIR-3D-GRE for Gd-EOB-DTPA-enhanced liver MRI. © The Foundation Acta Radiologica 2014.

    Professor H Winter. It was with great sadness that we learnt of the death of colleague and friend Professor Hannspeter Winter in Vienna on the 8 November 2006. In memory of him and the contribution he made both to our conference and to the field of the physics of highly charged ions we dedicate these proceedings. Hannspeter was one of our distinguished invited speakers at HCI2006 and gave a talk on the status of the ITER programme. His invited paper on the subject is included in these proceedings. Hannspeter will be particularly remembered for his pioneering work on ion-surface interactions that, together with his colleagues at the Vienna University of Technology (TUW), has stimulated a worldwide experimental and theoretical interest in this field. He was appointed Director of the Institut fuer Allgemeine Physik at TUW in 1987 and using both his scientific and management skills has made it one of the leading university physics laboratories in the world. His research publications, of which there are 270, have inspired many others to work in the field of atomic and plasma physics. He was also a great European playing a major role in the EURATOM fusion programme, the European Physical Society and the International Union of Pure and Applied Physics and was an evaluator and advisory board member for many national and international institutions. Hannspeter was also an interesting and friendly social companion with interests in current affairs, music and fine wines and will be greatly missed both on a scientific and social level. Our condolences go to his wife Renate, son Dorian and his relatives. R W McCullough Co-chair HCI2006

  12. Estimating the intrinsic limit of the Feller-Peterson-Dixon composite approach when applied to adiabatic ionization potentials in atoms and small molecules

    Feller, David

    2017-07-01

    Benchmark adiabatic ionization potentials were obtained with the Feller-Peterson-Dixon (FPD) theoretical method for a collection of 48 atoms and small molecules. In previous studies, the FPD method demonstrated an ability to predict atomization energies (heats of formation) and electron affinities well within a 95% confidence level of ±1 kcal/mol. Large 1-particle expansions involving correlation consistent basis sets (up to aug-cc-pV8Z in many cases and aug-cc-pV9Z for some atoms) were chosen for the valence CCSD(T) starting point calculations. Despite their cost, these large basis sets were chosen in order to help minimize the residual basis set truncation error and reduce dependence on approximate basis set limit extrapolation formulas. The complementary n-particle expansion included higher order CCSDT, CCSDTQ, or CCSDTQ5 (coupled cluster theory with iterative triple, quadruple, and quintuple excitations) corrections. For all of the chemical systems examined here, it was also possible to either perform explicit full configuration interaction (CI) calculations or to otherwise estimate the full CI limit. Additionally, corrections associated with core/valence correlation, scalar relativity, anharmonic zero point vibrational energies, non-adiabatic effects, and other minor factors were considered. The root mean square deviation with respect to experiment for the ionization potentials was 0.21 kcal/mol (0.009 eV). The corresponding level of agreement for molecular enthalpies of formation was 0.37 kcal/mol and for electron affinities 0.20 kcal/mol. Similar good agreement with experiment was found in the case of molecular structures and harmonic frequencies. Overall, the combination of energetic, structural, and vibrational data (655 comparisons) reflects the consistent ability of the FPD method to achieve close agreement with experiment for small molecules using the level of theory applied in this study.

    In patients with rotator cuff tears, muscle degeneration is known to be a predictor of irreparable tears and poor outcomes after surgical repair. Fatty infiltration and volume of the whole muscles constituting the rotator cuff were quantitatively assessed using 3-dimensional 2-point Dixon magnetic resonance imaging. Ten shoulders with a partial-thickness tear, 10 shoulders with an isolated supraspinatus tear, and 10 shoulders with a massive tear involving supraspinatus and infraspinatus were compared with 10 control shoulders after matching age and sex. With segmentation of muscle boundaries, the fat fraction value and the volume of the whole rotator cuff muscles were computed. After reliabilities were determined, differences in fat fraction, muscle volume, and fat-free muscle volume were evaluated. Intra-rater and inter-rater reliabilities were regarded as excellent for fat fraction and muscle volume. Tendon rupture adversely increased the fat fraction value of the respective rotator cuff muscle (P muscle volume was significantly decreased in the infraspinatus (P = .035) and increased in the teres minor (P = .039). With subtraction of fat volume, a significant decrease of fat-free volume of the supraspinatus muscle became apparent with a massive tear (P = .003). Three-dimensional measurement could evaluate fatty infiltration and muscular volume with excellent reliabilities. The present study showed that chronic rupture of the tendon adversely increases the fat fraction of the respective muscle and indicates that the residual capacity of the rotator cuff muscles might be overestimated in patients with severe fatty infiltration.

  14. Professor-psicopedagogo: o que este profissional faz na escola

    Directory of Open Access Journals (Sweden)

    Caroline Andrea Pottker

    Full Text Available Este estudo teve como objetivo identificar o porquê da presença do professor-psicopedagogo nas escolas e qual a função que este desempenha dentro delas, bem como, suas implicações no processo ensino-aprendizagem. Para tanto, foram entrevistados dez professores-psicopedagogos, pertencentes a cinco escolas localizadas no Estado do Paraná. Os resultados apontaram que o cargo de professor-psicopedagogo foi ocupado por professores que tinham o título de especialista em Psicopedagogia, os quais passaram a realizar avaliações psicopedagógicas dos alunos com dificuldades de aprendizagem. Segundo a maioria desses profissionais, uma de suas funções constitui-se em auxiliar o professor que apresenta em sala de aula alunos com dificuldades de aprendizagem, assim como tentar compreender o porquê de estes alunos não estarem aprendendo, sobretudo, ajudá-los na reversão desta problemática. Concluímos que a atuação deste profissional nestas escolas pouco tem contribuído para resolução das dificuldades de aprendizagem, pois centram-se no indivíduo e não no processo ensino-aprendizagem.

  15. Hydrological and hydrogeological effects of an open repository in Forsmark. Final MIKE SHE flow modelling results for the Environmental Impact Assessment

    This report presents methodology and modelling results concerning a deep-rock repository for spent nuclear fuel in Forsmark. Specifically, the modelling tools MIKE SHE, MIKE 11 and MOUSE are used to quantify the groundwater inflow to the repository and associated hydrological and hydrogeological effects during the construction and operation phases. The modelling results presented in the report provide input to the Environmental Impact Assessment (EIA) that will be part of a permit application according to the Environmental Code. Based on an existing MIKE SHE model for Forsmark, the first step of the modelling process was to implement an updated hydrogeological model of the bedrock and to increase the vertical and horizontal extents of the model domain. Other model updates involve the vegetation classification, and implementation of SFR (final repository for short-lived radioactive waste) and the subsurface drainage system at the nearby nuclear power plant. The updated model was calibrated using measured data on groundwater levels in the Quaternary deposits and the bedrock, water levels in lakes, and stream discharges. The calibrated model was then used for simulation of undisturbed conditions (i.e. without the repository) as a reference for modelling results obtained for disturbed conditions (with the repository). The modelling results for undisturbed conditions that are presented in the report closely resemble those of the final MIKE SHE site descriptive modelling (SDM-Site Forsmark). The repository layout was implemented as pipe links (segments) in the modelling tool MOUSE, and the implemented layout was used for the modelling of disturbed conditions. The study uses an updated and verified MIKE SHE-MOUSE coupling routine that is specifically adapted for calculation of groundwater inflow to grouted rock tunnels. The vertical shafts of the repository are implemented in the form of MIKE SHE grid cells with atmospheric pressure. Modelling results for disturbed

    2016-01-01

    We discuss the categorization of 20 quantum mechanics problems by physics professors and undergraduate students from two honors-level quantum mechanics courses. Professors and students were asked to categorize the problems based upon similarity of solution. We also had individual discussions with professors who categorized the problems. Faculty members' categorizations were overall rated higher than those of students by three faculty members who evaluated all of the categorizations. The categories created by faculty members were more diverse compared to the categories they created for a set of introductory mechanics problems. Some faculty members noted that the categorization of introductory physics problems often involves identifying fundamental principles relevant for the problem, whereas in upper-level undergraduate quantum mechanics problems, it mainly involves identifying concepts and procedures required to solve the problem. Moreover, physics faculty members who evaluated others' categorizations express...

    2017-02-01

    Full Text Available Aim/Purpose: In the United States, faculty who wish to pursue promotion to the rank of professor do so without clear guidance or structure. Even the timing of such a process is nebulous. As such, an individual engages in agentic action to pursue the rank. Background: This study examined the experiences of faculty members who chose to pursue the application process to be promoted to professor but were rejected or dissuaded. Methodology: Utilizing a case study of one institutional setting, we conducted 10 in-depth qualitative interviews. Contribution: Very little is known about the process of promotion to full professor in the U.S. and even less empirical research exists. This study advances knowledge of the process and the experiences of those undertaking it. Findings: We learned that cues from the social context greatly influenced these faculty members’ sense of agency.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

    To assess the feasibility of T2*-corrected fat-signal fraction (FF) map by using the three-echo volume interpolated breath-hold gradient echo (VIBE) Dixon sequence to differentiate between malignant marrow-replacing lesions and benign red marrow deposition of vertebrae. We assessed 32 lesions from 32 patients who underwent magnetic resonance imaging after being referred for assessment of a known or possible vertebral marrow abnormality. The lesions were divided into 21 malignant marrow-replacing lesions and 11 benign red marrow depositions. Three sequences for the parameter measurements were obtained by using a 1.5-T MR imaging scanner as follows: three-echo VIBE Dixon sequence for FF; conventional T1-weighted imaging for the lesion-disc ratio (LDR); pre- and post-gadolinium enhanced fat-suppressed T1-weighted images for the contrast-enhancement ratio (CER). A region of interest was drawn for each lesion for parameter measurements. The areas under the curve (AUC) of the parameters and their sensitivities and specificities at the most ideal cutoff values from receiver operating characteristic curve analysis were obtained. AUC, sensitivity, and specificity were respectively compared between FF and CER. The AUCs of FF, LDR, and CER were 0.96, 0.80, and 0.72, respectively. In the comparison of diagnostic performance between the FF and CER, the FF showed a significantly larger AUC as compared to the CER (p = 0.030), although the difference of sensitivity (p = 0.157) and specificity (p = 0.157) were not significant. Fat-signal fraction measurement using T2*-corrected three-echo VIBE Dixon sequence is feasible and has a more accurate diagnostic performance, than the CER, in distinguishing benign red marrow deposition from malignant bone marrow-replacing lesions.

    To evaluate the diagnostic value of T2{sup *} mapping using 3D multi-echo Dixon gradient echo acquisition on gadoxetic acid-enhanced liver magnetic resonance imaging (MRI) as a tool to evaluate hepatic function. This retrospective study was approved by the IRB and the requirement of informed consent was waived. 242 patients who underwent liver MRIs, including 3D multi-echo Dixon fast gradient-recalled echo (GRE) sequence at 3T, before and after administration of gadoxetic acid, were included. Based on clinico-laboratory manifestation, the patients were classified as having normal liver function (NLF, n = 50), mild liver damage (MLD, n = 143), or severe liver damage (SLD, n = 30). The 3D multi-echo Dixon GRE sequence was obtained before, and 10 minutes after, gadoxetic acid administration. Pre- and post-contrast T2{sup *} values, as well as T2{sup *} reduction rates, were measured from T2{sup *} maps, and compared among the three groups. There was a significant difference in T2{sup *} reduction rates between the NLF and SLD groups (−0.2 ± 4.9% vs. 5.0 ± 6.9%, p = 0.002), and between the MLD and SLD groups (3.2 ± 6.0% vs. 5.0 ± 6.9%, p = 0.003). However, there was no significant difference in both the pre- and post-contrast T2{sup *} values among different liver function groups (p = 0.735 and 0.131, respectively). A receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve for using T2{sup *} reduction rates to differentiate the SLD group from the NLF group was 0.74 (95% confidence interval: 0.63–0.83). Incorporation of T2{sup *} mapping using 3D multi-echo Dixon GRE sequence in gadoxetic acid-enhanced liver MRI protocol may provide supplemental information for liver function deterioration in patients with SLD.

    Full Text Available Music videos are an audiovisual format that is created by the music industry for a performer’s public image and commercial purposes. This research aims to describe common practices in production and editing of current music videos regarding one particular aspect: the duration of the shot according to its frame. We carried out a textual analysis of Mike Posner’s video clip I took a Pill in Ibiza (Jon Jon Augustavo, 2016. In this case, the most frequent shots in the video clip are close shots, and the average duration is around two seconds. The average length of the shots creates a scale of durations which is equivalent to the scale of the size of the frames.

To test this a distributed hydrological model...... (conifer/broadleaf) and agricultural crops (grass, maize, wheat and barley) in different areal combinations. Initially, the SWET component was calibrated against plot scale field data from two forest sites to obtain vegetation parameter estimates for conifers and broadleaves. Subsequently, the catchment...... models were run for 10 years with predefined land use scenarios. MIKE SHE SWET simulated canopy interception and throughfall for conifers and broadleaf forests satisfactorily. The catchment simulations showed that replacing current conifer forests with broadleaves, resulted in a significant increase...

    In recent years research on the coupling of existing regional climate models and hydrology/land surface models has emerged. A major challenge in this emerging research field is the computational interaction between the models. In this study we present results from a full two-way coupling of the HIRHAM regional climate model over a 4000 km x 2800 km domain in 11 km resolution and the combined MIKE SHE-SWET hydrology and land surface models over the 2500 km2 Skjern river catchment. A total of 26 one-year runs were performed to assess the influence of the data transfer interval (DTI) between the two models and the internal HIRHAM model variability of ten variables. In general, the coupled model simulations exhibit less accurate performance than the uncoupled simulations which is to be expected as both models prior to this study have been individually refined or calibrated to reproduce observations. Four of six output variables from HIRHAM, precipitation, relative humidity, wind speed and air temperature, showed statistically significant improvements in RMSE with a reduced DTI as evaluated in the range of 12-120 min. For these four variables the perturbation induced HIRHAM variability was shown to correspond to 47% of the RMSE improvement when using a DTI of 120 min compared to a DTI of 12 min and the variability resulted in large ranges in simulated precipitation. Also, the DTI was shown to substantially affect computation time. The MIKE SHE energy flux and discharge output variables experienced little impact from the DTI.

  9. Effects of Land Use and Climate Change on Groundwater and Ecosystems at the Middle Reaches of the Tarim River Using the MIKE SHE Integrated Hydrological Model

    2015-06-01

    Full Text Available The Tarim basin is a unique ecosystem. The water from the Tarim River supports both wildlife and humans. To analyze the effects of both land use and climate changes on groundwater, a research site was established at Yingibazar, which is a river oasis along the middle section of the Tarim River. A hydrological survey was performed to assess the general water cycle in this area with special emphasis on groundwater replenishment as well as the impact of agricultural irrigation on the riparian natural vegetation with respect to salt transport and depth of groundwater. Although high-resolution input data is scarce for this region, simulation of water cycle processes was performed using the hydrological model MIKE SHE (DHI. The results of the calibrated model show that natural flooding is the major contributor to groundwater recharge. There is also a close interaction between irrigated agricultural areas and the adjacent natural vegetation for groundwater levels and salinity up to 300 m away from the fields. Furthermore, the source of water used for irrigation (i.e., river and/or groundwater has a high impact on groundwater levels and salt transportation efficiency. The ongoing expansion of agricultural areas is rapidly destroying natural vegetation, floodplains, and their natural flow paths. Our results show that more unstable annual Tarim floods will occur in the future under the background of climate change. Therefore, integrated hydrological simulations were also performed for 2050 and 2100 using MIKE SHE. The results confirm that after the glaciers melt in the Tian Shan Mountains, serious aquifer depletion and environmental degradation will occur in the area, causing great difficulties for the local people.

  14. Effects on surface hydrology and near-surface hydrogeology of an open repository in Laxemar Results of modelling with MIKE SHE

    Energy Technology Data Exchange (ETDEWEB)

    Maartensson, Erik; Gustafsson, Lars-Goeran (DHI Sverige AB, Goeteborg (Sweden)); Bosson, Emma (Swedish Nuclear Fuel and Waste Management Co., Stockholm (Sweden))

    2009-10-15

    This report presents the methodology and the results from the modelling of an open repository for spent nuclear fuel in Laxemar. Specifically, the present work analyses the hydrological effects of the planned repository during the construction and operational phases when it is open, i.e. air-filled, and hence may cause a disturbance of the hydrological conditions in the surroundings. The numerical modelling is based on the SDM-Site Laxemar MIKE SHE model. The modelling was divided into three steps. The first step was to update the SDM-Site Laxemar model with a new hydrogeological bedrock model. The other main updates were an increase of the depth of the MIKE SHE model domain, enhanced vertical computational resolution and that the drainage of the Aespoe Hard Rock Laboratory was included in the model. The resulting model was used to simulate undisturbed natural conditions. The next step was to describe the open repository conditions, using Laxemar layout D2, by implementing the access tunnel, the repository tunnels and shafts in the model, and to simulate the consequences for the surface hydrology caused by an open repository under different conditions. The final step was a sensitivity analysis that aimed to investigate the sensitivity of the modelled effects of the open repository to the hydrogeological properties of the bedrock and the Quaternary deposits, the sediments under the sea, and changes in boundary conditions. The model covers an area of 34 km2. The groundwater divides were assumed to coincide with the surface water divides; thus, a no-flow boundary condition was used at the horizontal boundaries, except in the Quaternary deposit layers towards the sea where a time-varying boundary condition describing the sea-level in the area was used. In the bedrock layers, however, a no-flow boundary condition was applied. Also the bottom boundary was described as a no-flow boundary. The transient top boundary condition was based on meteorological data gathered at

    This issue includes a special section on computational fluid dynamics (CFD) in memory of the late Professor Kunio Kuwahara, who passed away on 15 September 2008, at the age of 66. In this special section, five articles are included that are based on the lectures and discussions at `The 7th International Nobeyama Workshop on CFD: To the Memory of Professor Kuwahara' held in Tokyo on 23 and 24 September 2009. Professor Kuwahara started his research in fluid dynamics under Professor Imai at the University of Tokyo. His first paper was published in 1969 with the title 'Steady Viscous Flow within Circular Boundary', with Professor Imai. In this paper, he combined theoretical and numerical methods in fluid dynamics. Since that time, he made significant and seminal contributions to computational fluid dynamics. He undertook pioneering numerical studies on the vortex method in 1970s. From then to the early nineties, he developed numerical analyses on a variety of three-dimensional unsteady phenomena of incompressible and compressible fluid flows and/or complex fluid flows using his own supercomputers with academic and industrial co-workers and members of his private research institute, ICFD in Tokyo. In addition, a number of senior and young researchers of fluid mechanics around the world were invited to ICFD and the Nobeyama workshops, which were held near his villa, and they intensively discussed new frontier problems of fluid physics and fluid engineering at Professor Kuwahara's kind hospitality. At the memorial Nobeyama workshop held in 2009, 24 overseas speakers presented their papers, including the talks of Dr J P Boris (Naval Research Laboratory), Dr E S Oran (Naval Research Laboratory), Professor Z J Wang (Iowa State University), Dr M Meinke (RWTH Aachen), Professor K Ghia (University of Cincinnati), Professor U Ghia (University of Cincinnati), Professor F Hussain (University of Houston), Professor M Farge (École Normale Superieure), Professor J Y Yong (National

    Professor Peter Higgs played a key role in the development of the Standard Model, our current theory of fundamental physics. The search for the Higgs Boson is the centrepiece of the LHC programme at CERN, and the existence of this famously elusive particle is likely to be confirmed or refuted with data currently being collected, using apparatus partly designed at Bristol. Professor Higgs will introduce the ideas of spontaneous symmetry breaking, and discuss how these developed from their application in condensed matter through the earlier work of Yoichiro Nambu and Jeffrey Goldstone, to the work of Robert Brout, Francois Englert and himself in 1964. The subsequent application of these ideas to electroweak theory will be discussed briefly.

    Full Text Available The task of the university professor is a mission and not simply a profession and that is why higher education should be impregnated with values. Nowadays education is articulated into three areas: the State, the Market and the Volunteering, but no one of these three sectors by themselves has covered the needs of all the citizens, there have always been losers, therefore the conjunction of the three sectors became necessary. Communitarianism promotes an ethical-social pact that favors the progress of society without nullifying the individual dimension. It believes that the university is the space where a communitarian consciousness should be promoted to generate a social capital by means of education and it is a privilege place to substantiate the moral identity of the person beginning with the commitment of the professor with the university student.

    2010-03-01

    The new guidelines for undergraduate courses in the field of health care imply a need to prepare professionals to deal with life and death. To study death and dying in the context of nurse education means to contribute to the humanization of education and to preparing humanistic and critical professionals. We performed individual interviews with professors so that each could reveal their thoughts about experiencing death and dying in the educational relationship between nurse/professor and the nursing student in the hospital environment. Content analysis was performed using ideas close to those of Heidegger, revealing that education towards the concept and experience of death appears to be possible only if there is reflection regarding human existence, thoughts, and accepting finitude. By understanding one's own attitudes towards death and existence, it is possible to perceive possibilities in education for care in the death process.

    Full Text Available In the first part of this article, the authors explain how the teaching role is affected by certain social and cultural changes, like the knowledge society emergence, the universities orientation towards marketing, the constant demand and pressure exerted on teachers to publish, the loss of the ethical sense in the academic activity and the disparity of tasks that are being assigned to the university professors. In view of the above, a comprehensive model, compound by two concepts –personal and professional– of a university professor is proposed; in fact, this model incorporates and summarises different contributions regarding this theme. Finally, this article aims to defend the need to understand the teaching role as a vocation, in the broadest sense of the word, a vocation carries the inclination to pursue an aim: the education of those students that teachers have in charge.

  7. Professor Created On-line Biology Laboratory Course

    Bowman, Arthur W.

    2010-01-01

    This paper will share the creation, implementation, and modification of an online college level general biology laboratory course offered for non-science majors as a part of a General Education Curriculum. The ability of professors to develop quality online laboratories will address a growing need in Higher Education as more institutions combine course sections and look for suitable alternative course delivery formats due to declining departmental budgets requiring reductions in staffing, equipment, and supplies. Also, there is an equal or greater need for more professors to develop the ability to create online laboratory experiences because many of the currently available online laboratory course packages from publishers do not always adequately parallel on-campus laboratory courses, or are not as aligned with the companion lecture sections. From a variety of scientific simulation and animation web sites, professors can easily identify material that closely fit the specific needs of their courses, instructional environment, and students that they serve. All too often, on-campus laboratory courses in the sciences provide what are termed confirmation experiences that do NOT allow students to experience science as would be carried out by scientists. Creatively developed online laboratory experiences can often provide the type of authentic investigative experiences that are not possible on-campus due to the time constraints of a typical two-hour, once-per-week-meeting laboratory course. In addition, online laboratory courses can address issues related to the need for students to more easily complete missing laboratory assignments, and to have opportunities to extend introductory exercises into more advanced undertakings where a greater sense of scientific discovery can be experienced. Professors are strongly encourages to begin creating online laboratory exercises for their courses, and to consider issues regarding assessment, copyrights, and Intellectual Property

  8. Numerical Limitations of 1D Hydraulic Models Using MIKE11 or HEC-RAS software – Case study of Baraolt River, Romania

    MIKE 11 is an advanced hydroinformatic tool, a professional engineering software package for simulation of one-dimensional flows in estuaries, rivers, irrigation systems, channels and other water bodies. MIKE 11 is a 1-dimensional river model. It was developed by DHI Water · Environment · Health, Denmark. The basic computational procedure of HEC-RAS for steady flow is based on the solution of the one-dimensional energy equation. Energy losses are evaluated by friction and contraction / expansion. The momentum equation may be used in situations where the water surface profile is rapidly varied. These situations include hydraulic jumps, hydraulics of bridges, and evaluating profiles at river confluences. For unsteady flow, HEC-RAS solves the full, dynamic, 1-D Saint Venant Equation using an implicit, finite difference method. The unsteady flow equation solver was adapted from Dr. Robert L. Barkau’s UNET package. Fluid motion is controlled by the basic principles of conservation of mass, energy and momentum, which form the basis of fluid mechanics and hydraulic engineering. Complex flow situations must be solved using empirical approximations and numerical models, which are based on derivations of the basic principles (backwater equation, Navier-Stokes equation etc.). All numerical models are required to make some form of approximation to solve these principles, and consequently all have their limitations. The study of hydraulics and fluid mechanics is founded on the three basic principles of conservation of mass, energy and momentum. Real-life situations are frequently too complex to solve without the aid of numerical models. There is a tendency among some engineers to discard the basic principles taught at university and blindly assume that the results produced by the model are correct. Regardless of the complexity of models and despite the claims of their developers, all numerical models are required to make approximations. These may be related to geometric

    Midwifery in Dalmatia was highly undeveloped at the beginning of the XIX century. The health report from 1813 suggested that there were only 48 midwives in the whole province, and none of them with a degree from the midwifery school. After abolishing the Central Schools ("Ecoles Centrales"), which were founded at the time of French reign, and which had the university range, the professors who stayed in Zadar continued their work and teaching in the Midwifery School, which was founded in 1820 according to the decision made by Emperor Franz I, and started working in 1821. Since the school was working continuously for the whole century, a lot of professors and principals passed through. Protomedicus of Dalmatia officially performed the duty of principals of the Midwifery School. Their life and work biographies were gathered in this paper. Although the newcomers were mostly illiterate, very contemporary and valuable textbooks were used at that time. The professors of this school wrote some of these textbooks. This paper analyses those textbooks from the current medical science and praxis point of view, which points out to its significance and contribution of its authors to the reputation that the School enjoyed at that time.

    Quantitative PET image reconstruction requires an accurate map of attenuation coefficients of the tissue under investigation at 511 keV (μ-map), and in order to correct the emission data for attenuation. The use of MRI-based attenuation correction (MRAC) has recently received lots of attention in the scientific literature. One of the major difficulties facing MRAC has been observed in the areas where bone and air collide, e.g. ethmoidal sinuses in the head area. Bone is intrinsically not detectable by conventional MRI, making it difficult to distinguish air from bone. Therefore, development of more versatile MR sequences to label the bone structure, e.g. ultra-short echo-time (UTE) sequences, certainly plays a significant role in novel methodological developments. However, long acquisition time and complexity of UTE sequences limit its clinical applications. To overcome this problem, we developed a novel combination of Short-TE (ShTE) pulse sequence to detect bone signal with a 2-point Dixon technique for water-fat discrimination, along with a robust image segmentation method based on fuzzy clustering C-means (FCM) to segment the head area into four classes of air, bone, soft tissue and adipose tissue. The imaging protocol was set on a clinical 3 T Tim Trio and also 1.5 T Avanto (Siemens Medical Solution, Erlangen, Germany) employing a triple echo time pulse sequence in the head area. The acquisition parameters were as follows: TE1/TE2/TE3=0.98/4.925/6.155 ms, TR=8 ms, FA=25 on the 3 T system, and TE1/TE2/TE3=1.1/2.38/4.76 ms, TR=16 ms, FA=18 for the 1.5 T system. The second and third echo-times belonged to the Dixon decomposition to distinguish soft and adipose tissues. To quantify accuracy, sensitivity and specificity of the bone segmentation algorithm, resulting classes of MR-based segmented bone were compared with the manual segmented one by our expert neuro-radiologist. Results for both 3 T and 1.5 T systems show that bone segmentation applied in several

    Full Text Available The public transportation system along the Kapuas River, Central Kalimantan are highly depend on water transportation. Natural condition gives high distribution to the smoothness of the vessel traffic along the Kapuas Murung River. The local government has planned to build specific port for stock pile at the Batanjung which would face with natural phenomena of sedimentation and erosion at a river mouth. Erosion and sedimentation could be predicted not only by field observing but it is also needed hypotheses using software analysis. Hydrodynamics and transport sediment models by Mike 21 HDFM-MT software will be applied to describe the position of sedimentations and erosions at a river mouth. Model is assumed by two different river conditions, wet and dry seasons. Based on two types of conditions the model would also describe the river flow and sediment transport at spring and neap periods. Tidal fluctuations and a river current as field observation data would be verified with the result of model simulations. Based on field observation and simulation results could be known the verification of tidal has an 89.74% correlation while the river current correlation has 43.6%. Moreover, based on the simulation the sediment patterns in flood period have a larger area than ebb period. Furthermore, the erosion patterns dominantly occur during wet and dry season within ebb period. Water depths and sediment patterns should be considered by the vessels that will use the navigation channel at a river mouth.

    Full Text Available This paper presents the results of testing the applicability of the MIKE Basin model for simulating the efficiency of scenarios for reducing water pollution. The model has been tested on the Olšava River Basin (520 km2 which is a typical rural region with a heterogeneous mix of pollution sources with variable topography and land use. The study proved that the model can be calibrated successfully using even the limited amount of data typically available in rural basins. The scenarios of pollution reduction were based on implementation and intensification of municipal wastewater treatment and conversion of arable land on fields under the risk of soil erosion to permanent grassland. The application of simulation results of these scenarios with proposed measures proved decreasing concentrations in downstream monitoring stations. Due to the practical applicability of proposed measures, these could lead to fulfilment of the water pollution limits required by the Czech and EU legislation. However, there are factors of uncertainty that are discussed that may delay or limit the effect of adopted measures in small rural basins.

    The papers in this special feature have been contributed by scientific partners in international research projects and from former PhD students of the Editor-in-Chief of this journal, Professor Dr Peter Hauptmann. The motivation for this feature is the occasion of Peter Hauptmann's 65th birthday on 24 July 2009 and his retirement from his chair at the Otto-von-Guericke-University, Magdeburg, Germany this autumn. Peter graduated in Physics at the Technical University Dresden and received his PhD from the Technical University Leuna-Merseburg in 1973. He habilitated in 1979. With his appointment at the Faculty of Electrical Engineering and Information Technology in 1985 the Chair of Measurement Science extended its profile to the fast growing area of sensors. Peter was one of the very early developers of ultrasonic sensor systems for process monitoring and quality assurance. The working style here was characteristic of all his future activities. He combined his background in theory and experiment on ultrasonic wave propagation and its application to material science with the advantages of rapidly developing capabilities in microelectronics and data processing. The results have meanwhile found their way into products that are now on the market worldwide. Germany's reunification opened the door to the international sensor community and the most challenging sensor research areas. Peter Hauptmann very soon became a well respected colleague and was consequently appointed as member of the Technical Program Committee of the most important sensor conferences, elected member and head of expert groups of research associations and funding organizations, and of course reviewer of many scientific journals. Nowadays Peter Hauptmann can rightly be called one of the key players in the area of sensors. Professor Hauptmann's research interests combine fundamental aspects of the sensor transduction scheme with application issues up to the use of the sensor system in the industrial world

    Purpose To determine the degree of preoperative fatty degeneration within muscles, postoperative longitudinal changes in fatty degeneration, and differences in fatty degeneration between patients with full-thickness supraspinatus tears who do and those who do not experience a retear after surgery. Materials and Methods This prospective study had institutional review board approval and was conducted in accordance with the Committee for Human Research. Informed consent was obtained. Fifty patients with full-thickness supraspinatus tears (18 men, 32 women; mean age, 67.0 years ± 8.0; age range, 41-91 years) were recruited. The degrees of preoperative and postoperative fatty degeneration were quantified by using a two-point Dixon magnetic resonance (MR) imaging sequence; two radiologists measured the mean signal intensity on in-phase [S(In)] and fat [S(Fat)] images. Estimates of fatty degeneration were calculated with "fat fraction" values by using the formula S(Fat)/S(In) within the supraspinatus, infraspinatus, and subscapularis muscles at baseline preoperative and at postoperative 1-year follow-up MR imaging. Preoperative fat fractions in the failed-repair group and the intact-repair group were compared by using the Mann-Whitney U test. Results The preoperative fat fractions in the supraspinatus muscle were significantly higher in the failed-repair group than in the intact-repair group (37.0% vs 19.5%, P muscle tended to progress at 1 year postoperatively in only the failed-repair group. Conclusion MR imaging quantification of preoperative fat fractions by using a two-point Dixon sequence within the rotator cuff muscles may be a viable method for predicting postoperative retear.

    2003-05-01

    A medical practitioner, Professor Cottard, features in Marcel Proust's A la recherche du temps perdu, which has been described as one of the supreme achievements of world literature. Proust modelled the character of Cottard on the real-life Parisian neurologist and psychiatrist Dr Jules Cotard (1840-1889). Marcel Proust's father, Dr Adrien Proust, was an eminent Parisian surgeon and a contemporary of Cotard. A review of the biographical literature (in French) relating to Dr Jules Cotard and an analysis of his published work (in English and French) have revealed a striking parallelism between the lives of the fictional Cottard and Jules Cotard.

  6. Transactional sex and sexual harassment between professors and students at an urban university in Benin.

    2016-07-01

    This paper adds to discussion of transactional sex relationships in Africa by examining the distinction between transactional sex and sexual harassment in the context of professor-student relationships and their inherent power dynamics. By exploring the ways in which female university students in urban Benin toe the line between empowered agent and victim, I show how the power differential between professor and student obstructs the professor's ability to objectively determine consent, and examine why, in spite of this differential, male professors are frequently perceived as the victims of these relationships. Ethnographic data were gathered through participant observation on a public university campus in Benin and in-depth interviews and focus groups with 34 students and 5 professors from that university. Findings suggest that the problem of sexual harassment on campus will be difficult to address so long as transactional sex relationships between professors and students are permitted to continue.

    This study aimed at analyzing how the undergraduate student perceives professor's performance in the teaching-learning process, in courses using the critical pedagogy and dialogical competence approach, in the Nursing Bachelor's Program, from 2005 to 2006. An instrument for the assessment of the professors performance was used and answers from 142 students were analyzed. Through thematic analysis, the following meaning units were outlined approaching the teaching-learning process, professor/student relationship and evaluation. For most students, professors who stimulate the critical-reflexive process, coherent with the problem-solving methodology, facilitate the teaching-learning process. For others, this process is facilitated when the professor is more demanding in contrast with the problem-solving approach. The professor-student relationship was facilitated by the establishment of bonds. Students did few comments about evaluation, indicating the need of a formative evaluation, which is a work in progress.

    Full Text Available In 1939, Dorothy Garrod became the first woman Professor in either Cambridge or Oxford. Garrod at the time was Director of Studies at Newnham College, Cambridge University and had been in charge of excava­tions in Gibraltar, Western Judaea, Southern Kurdistan and Mount Carmel for which she is now renowned. Trained by Marett at Oxford and Abbe Henri Breuil in France, she was one of our finest archaeologists. By 1939, Garrod had unearthed the well-preserved skull of 'Abel', a Neanderthal child, in Gibraltar, discovered and named the Natufian culture while excavating Shukba near Jerusalem, directed the long term, large scale excavations at Mount Carmel and traveled with Bruce Howe as her assistant to explore Bacho Kiro in Bulgaria. Once elected Professor, she became instrumental in establishing Archaeology and Anthropology as a full degree course and influential in Cambridge's decision to admit women to full membership in 1948. After retirement, she continued excavating in Lebanon and France. Here, with her close friend Suzanen Cassou de Saint Mathurin, she discovered the superb Magdalenian sculptured frieze at Angles-sur-l'Anglin.

    Full Text Available The presence of the Burnout syndrome in professors may be regarded as a deterioration of their mental health with negative impacts on their job performance. It is known that teachers develop different activities in the areas of teaching, outreach and research. This study aims to analyze the relationship between the Burnout syndrome and self-efficacy beliefs and the academic performance in professors of the psychology and dentistry programs at a private university in the city of Barranquilla. This study is empirical and analytical with a descriptive-correlational design. The study population consisted of 93 teachers of the psychology and dentistry programs. To choose the sample, a non-probabilistic sample was used according to the inclusion and exclusion criteria that allowed selecting a total of 36 teachers who met the criteria for the study. The instruments that were used in this study was the Maslach Burnout Inventory (MBI, 1981 adapted by Seisdedos (1997, and the Teachers’ Self-Efficacy Beliefs of Tschannen-Moran and Woolfolk (2001 adapted by Covarrubias and Mendoza (2016. According to the results, it was observed that there is no significant relationship between Burnout, Self-efficacy Belief and the academic performance.

    During the conference on the methods of differential geometry in physics in Warsaw in June 1976, Professor Wheeler gave an interview for the Czechoslovak Journal of Physics A. After Professor Wheeler authorized the English version in January 1977, the Czech translation was published in \\v{C}eskoslovensk\\'y \\v{c}asopis pro fyziku A (1978) and soon afterwards the Polish translation appeared in Postepy fizyky. After John Wheeler's recent death it occurred to me that it would now be appropriate to publish the original interview from 1976 so that it would not be lost to English readers; and so, despite being more than 30 years old, the interview appeared in the special issue on quantum gravity of "General Relativity and Gravitation" dedicated to the memory of J. A. Wheeler. John Wheeler would now surely add more about black holes in nuclei of galaxies, not mentioning just Cygnus X-1, when discussing cosmology he would undoubtedly address the problem of dark energy etc. However, in the conversation about Einstein a...

  17. Homage to Professor Hans-Åke Gustafsson

    2010-01-01

    It was with deep sadness that we learned of the death of Professor Hans-Åke Gustafsson, an internationally recognized scientist, beloved colleague and friend. He passed away on Wednesday January 13th at the Lund University Hospital, surrounded by his loved ones, after a short battle against cancer. This is a great loss for all of us in ALICE and the whole heavy ion community. Hans-Åke, Professor at Lund University, was one of the pioneers of heavy ion physics with relativistic beams since its very beginning. He started his research at CERN, as a fellow at the ISOLDE ion beam facility, and immediately after, in the early 1980 joined the Plastic Ball collaboration at the Bevalac. One of the seminal papers of the field on the discovery of collective flow in relativistic nuclear collisions, co-authored by Hans-Åke, Hans Gutbrod and colleagues, stems from this period. From that point on he was always at the forefront of research with relativistic nuclear beams, being for three de...

    Full Text Available Este trabalho tem como objetivo apresentar uma discussão referente à problemática da vivência diária do professor/professora homossexual frente à instituição escolar, cujo pressuposto inicial parte da premissa que estes professores sofreram e vem sofrendo, algum tipo de preconceito devido sua orientação sexual. No desenvolvimento, partimos para uma abordagem qualitativa e fundamentando-se na análise de discurso, ou seja, conhecendo as experiências de professores e professoras por meio de suas narrativas. Para isso foram entrevistados dois professores gays e uma professora lésbica, todos com ensino superior, que atuam ou atuaram no Ensino Fundamental II e no Ensino Médio. Nossa estratégia metodológica acontece em duas situações: A primeira, por meio de um questionário prévio composto de dez questões de identificação pessoal no intuito de traçar um perfil dos entrevistados. No segundo momento, entrevistas semi – estruturadas, com perguntas que focaram mais especificamente a percepção dos professores/professoras sobre a homofobia na escola. Nosso resultado é composto por relatos onde pudemos identificar a escola como um ambiente que reflete o sexismo que perpassa toda a sociedade, reproduzindo com frequência, as estruturas sociais, reforçando os preconceitos e privilégios de um sexo sobre o outro. Desta forma, percebemos que o heterossexismo está tão arraigado na cultura, que se torna invisível em muitas de suas atitudes quase sutis, como por exemplo, em brincadeiras e piadas. O universo escolar reproduz os preconceitos da sociedade e, na tentativa de evitar o convívio dos alunos heterossexuais, com pessoas homossexuais, faz da homossexualidade o maior alvo da discriminação. Concluímos, portanto, que as desigualdades entre os sexos e a marginalização dos homossexuais acabam gerando vítimas de uma sociedade inacabada, de repressão, opressão e desinformação. Por fim, está sociedade esta em constante

    2013-11-01

    Prior qualitative research has demonstrated that female college students may utilize their professors as support providers when they experience sexual assault and intimate partner violence victimization. To further explore this phenomenon, the present study used a random sampling design on two college campuses to examine the following questions: (a) Are student disclosures of crime victimization a common occurrence for college professors? (b) What is the nature of college professors' most recent disclosure of crime victimization? and (c) Do professor characteristics predict receiving a student disclosure of victimization? Implications of these findings as well as directions for future research will be discussed.

    In honor of one of the most prolific and exciting scientists of the second half of the last century, a memorial meeting was organized by the Institute of Advanced Studies at Nanyang Technological University for Professor Abdus Salam's 90th Birthday in January 2016. Salam believed that "scientific thought is the common heritage of all mankind" and that the developing world should play its part, not merely by importing technology but by being the arbiter of its own scientific destiny. That belief saw him rise from humble beginnings in a village in Pakistan to become one of the world's most original and influential particle physicists, culminating in the 1979 Nobel Prize (shared with Glashow and Weinberg) for contributions to electroweak unification, which forms an integral part of the Standard Model. The book collected the papers presented at this memorable event which saw many distinguished scientists participating as speakers to reflect on Prof Salam's great passion for the science and achievements.

    Full Text Available Este trabalho investiga a interferência do discurso de autoajuda nas representações de professor, construídas por alunos-mestres no contexto de formação de professores de língua. O embasamento teórico ancora-se no conceito de transdisciplinaridade como um fator central para a prática científica pós-moderna em Linguística Aplicada. Os resultados mostram que os discursos da autoajuda responsabilizam os professores tanto pelo sucesso quanto pelo fracasso de seus aprendizes. Consequentemente, o uso desse tipo de linguagem, durante os cursos de treinamento de professores, pode camuflar o empoderamento do professor, o que, por sua vez, pode comprometer a sua formação

Nessa perspectiva, esta conferência visa a apresentar uma pesquisa que discute a prática pedagógica alicerçada nas tecnologias digitais (TD como instrumentos mediadores. Considerando que a formação de professores é um processo contínuo, foi elaborada uma proposta de formação, para os egressos da licenciatura em Matemática de um Instituto Federal, no início de sua prática docente . A proposta foi denominada T-PROIM – Tecnologias na Prática docente de pROfessores Iniciantes de Matemática. Uma rede social na Internet (RSI foi implementada por meio da plataforma Elgg para apoiar a referida formação. Essa visou a possibilitar a integração das TD à prática docente e fundamentou-se na teoria sócio-histórica. A pesquisa foi descritiva e explicativa, por meio de um estudo de caso e a abordagem foi, predominantemente, qualitativa. As técnicas de coleta de dados foram questionário, entrevistas, observação e registro dos conteúdos postados na RSI. Para tanto, inicialmente, caracterizam-se redes sociais na internet. A seguir, são apresentados os aspectos metodológicos, as características da formação T-PROIM e a análise macro da experimentação da referida formação. Finalizando, são tecidas algumas considerações sobre a pesquisa. A flexibilidade da formação e da configuração de recursos RSI foi considerada importante para o contexto educacional.

O suporte teórico veio dos Estudos Culturais e dos Estudos Surdos. Foram entrevistados 10 professores surdos de escolas do Rio Grande do Sul, sendo suas entrevistas realizadas em LIBRAS e gravadas em vídeo. As perguntas das entrevistas foram: qual a função do ensino de Língua de Sinais; se os professores viam relação entre este ensino e o empoderamento dos alunos; o que professores de outras disciplinas achavam dos professores dessa disciplina (LS; qual a relação entre identidade surda e currículo de língua de sinais. A análise das entrevistas mostrou que os professores reconhecem a importância deste ensino e sua relevância para as identidades surdas, mas relataram dificuldades como: insuficiente participação dos alunos na comunidade surda; isolamento dos professores surdos em algumas escolas, sem terem com quem trocar idéias; discriminação em relação aos professores de LIBRAS; insegurança de alguns professores sobre o currículo trabalhado. A análise mostrou aspectos positivos, mas também mostrou que ainda há muito o que fazer no ensino escolarizado de LIBRAS.

    Full Text Available The goal of this article is to offer the results of a pilot study which examined the personality type and teaching style preferences of faculty who elected to teach an on-line course. The article will present a description of personality assessments, including the Myers-Briggs Type Indicator (MBTI and Anthony Gregorc's Transaction Ability Inventory used to determine teaching tendencies and styles. In addition, a structured written questionnaire developed by the researchers was used to assess teacher satisfaction with worldwide web-based instruction. Utilizing the results of these psychological assessments, a preliminary analysis of the personal characteristics of college professors who chose to teach on line will be presented. This pilot study found that some preferred teaching styles may be more compatible with the dynamics of distance learning formats. By determining successful teaching styles for on-line courses, we can develop more effective faculty development programs to assist others in successfully transitioning into the cyber-teaching and learning environment.

    Science.gov (United States)

    Suematsu, M; Aiso, S

    2001-06-01

    Ito cells are liver-specific pericytes which were first described as Fett Speicherung Zellen, the fat-storing cells encircling outside sinusoidal endothelial cells, in 1951 by the late professor Toshio Ito. His pioneering approaches for morphological characterization of the cells stimulate investigators to further examine their functional roles in liver homeostasis: a body of evidence has been accumulated in recent years showing that the cells play a crucial role in storage and delivery of vitamin A, regulation of sinusoidal tone and local blood supply, and tissue repair and fibrosis. It is now widely accepted that microvascular pericytes including Ito cells serve as a key player that controls angiogenesis. Furthermore, recent studies support a concept that Ito cells constitutes a bridging apparatus mediating bidirectional metabolic interactions between sinusoids and hepatocytes, utilizing prostanoids and/or gaseous mediators such as nitric oxide and carbon monoxide as signaling molecules. This article reviews researches on this liver-specific pericyte and its leading roles in recent development of pericyte biology.

    Full Text Available Nowadays sophisticated authoring tools allow developers to design and develop sophisticated web sites, in a fraction of the time that was required a few years ago. These tools have also allowed non-experienced users to create their own web pages, contributing in that sense to the expansion of the Internet. Nevertheless, while most of these sites are technically correct (links work fine, they too often result to be very difficult, and sometimes impossible, to be used. Our position is that the use of development tools is not sufficient. The development of web sites, as any other software requires of a methodology that maximizes the chances of the project success. In this paper we present a user-centered methodology employed in the development of a web site that will help physics professors of high school to communicate among them, and to share their experiences. The characteristics of the methodology and its different stages are detailed in this paper and the final product is presented as well as future works.

    Objective This study developed and examined the psychometric properties of a newly formed measure designed to assess professor/instructor bullying, as well as teacher bullying occurring prior to college. Additionally, prevalence of instructor bullying and characteristics related to victims of instructor bullying were examined. Participants Participants were 337 college students recruited in 2012 from a northeastern university. Methods An online questionnaire was administered to college students. A split-half, cross-validation approach was employed for measurement development. Results The measure demonstrated strong criterion validity and internal consistency. Approximately half of students reported witnessing professor/instructor bullying and 18% reported being bullied by a professor/instructor. Report of teacher bullying occurring prior to college was related to professor/instructor bullying in college, and sex was a moderating variable. Conclusion College students perceive instructor bullying as occurring but may not know how to properly address it. Prevention efforts should be made by university administrators, faculty and staff.

Methods: A cross-sectional study was carried out with 121 professors at one of the campuses of a state university in the State of Paraná, using a questionnaire created by Baecke and adapted for the study. Results: The analyzed group presented a level of inadequate physical activity of 54.4%, with mean body mass of 26.20, considered overweight. Conclusion: The study indicated that professors do not practice physical activity at the level recommended by the World Health Organization; therefore, they are, for the most part, sedentary and have complaints of anxiety. It is advisable to carry out actions aimed at the health of the professors, directed to the modification in the lifestyle, with regular practice of physical activities and balanced diet, for the improvement of the quality of life.

This study seeks to analyze the subjective well-being, the time-use strategies, and the satisfaction with their use of time of PhD-holding professors with and without productivity grants from the National Council for Scientific and Technological Development (CNPq. A total of 83 professors participated in the study (48 with productivity grants, with an average age of 50 years. A total of 89% of participants were from public institutions. The majority of the participants exhibited high levels of negative affect and low-average levels of satisfaction with their use of time. There was no difference in the subjective well-being or in the satisfaction with the use of time when comparing professors who had received a CNPq grant with professors who had not received a CNPq grant. The most important reason for dissatisfaction with the use of time was an excess of work, whereas peer recognition was the primary achievement obtained with the work. How work demands and conditions influence the well-being of the professors is discussed in this study.

    2013-01-01

    Background: the learning styles are cognitive, emotional, and psychological characteristics, which function as relatively stable indicators of how teachers and students perceive, interact, and respond to their learning environments. Knowing students' styles allows teachers to have tools to improve medical education. Our objective was to identify learning styles in pediatric residents and professors from a pediatric hospital. Methods: a learning styles questionnaire was applied to residents and theirs professors; data was analyzed in SPSS 12 software. Results: the dominant learning style in pediatric residents was reflexive and for professors was theoretical. There wasn't any difference between sexes or between medical or surgical specialities. There was more correlation between professors and residents when there was an increase in training time. Conclusions: the learning styles between professors and residents are different, especially at the beginning of the medical specialty courses; that's why it is necessary to realize a confrontation between the students' learning styles and teaching methods used by professors to improve significant learning. To know learning styles gives residents an important alternative to find a better study strategy.

    This study investigated three questions: (1) What are Lebanese secondary school (Grade 9-12) biology teachers' and university biology professors' positions regarding biological evolution?, (2) How do participants' religious affiliations relate to their positions about evolutionary science?, and (3) What are participants' positions regarding evolution education? Participants were 20 secondary school biology teachers and seven university biology professors. Seventy percent of the teachers and 60% of the professors were Muslim. Data came from semi-structured interviews with participants. Results showed that nine (Christian or Muslim Druze) teachers accepted the theory, five (four Muslim) rejected it because it contradicted religious beliefs, and three (Muslim) reinterpreted it because evolution did not include humans. Teachers who rejected or reinterpreted the evolutionary theory said that it should not be taught (three), evolution and creationism should be given equal time (two), or students should be allowed to take their own stand. Two professors indicated that they taught evolution explicitly and five said that they integrated it in other biology content. One Muslim professor said that she stressed 'the role of God in creation during instruction on evolution'. It seems that years of studying and teaching biology have not had a transformative effect on how a number of teachers and professors think about evolution.

    Full Text Available A motivação é fundamental para o envolvimento dos estudantes na escola. Para a teoria da autodeterminação, o estilo motivacional do professor, que pode controlar ou promover a autonomia, contribui para fomentar a ocorrência de tipos qualitativamente diferenciados de motivação. Neste estudo, de natureza exploratória, foram analisadas as interações entre dois professores e seus alunos. A amostra foi composta de acordo com o desempenho de 39 professores na avaliação do estilo motivacional, mediante a aplicação de um instrumento de autorrelato, problemas na escola. Desse total, dois professores, um com estilo motivacional promotor de autonomia e outro com uma orientação para o controle, tiveram suas aulas observadas em sete sessões, com o objetivo de levantar dados para a elaboração de um protocolo que continha categorias de interações. Foram então realizadas outras sete sessões de observação. Os resultados indicaram que, apesar de terem sido encontradas diferenças entre os desempenhos na avaliação do estilo motivacional, os professores interagiram com seus alunos de modo preferencialmente controlador. No entanto, o professor que promovia a autonomia interagiu de modo menos controlador no gerenciamento do tempo destinado para a realização das atividades em classe quando comparado ao professor controlador, além de oferecer feedback informativo. As implicações educacionais dos resultados são analisadas.

    Full Text Available Introduction This interview was conducted with Emerita Professor Margaret Rogers with the aim of providing a brief but informative summary of the relationship between translation and creative writing. Emerita Professor Rogers is in the Centre for Translation Studies, School of English and Languages, University of Surrey, UK. She is also the founder of Terminology Network at the Institute of Translation and Interpreting in the UK. Professor Rogers introduced creative writing into the translation curriculum some 10 years ago at her own university.   The Interview   RB[1]: Do you believe in a theory of translation? MR[2]: There are many ways of trying to understand and, where we can, explain translation in all its guises, loci and times. To talk about ‘a theory’ in this context doesn’t help much. There are many different approaches to the academic study of translation: rather simply put, the particular approach which we choose to adopt may depend on our object of study (e.g. literary translation or specialised translation, what we want to find out about this (e.g. are we interested in product or process, in a historical or contemporary perspective, what resources we have available (e.g. a fully funded research team or a solo effort and so on. Many projects are interdisciplinary—this has long been recognised—and translation scholars are becoming much more resourceful in identifying, adopting and adapting relevant approaches from intersecting disciplines such as comparative literature, cultural studies, history, linguistics, philosophy, psychology and sociology. Some scholars are now advocating a problem-based approach. In any research project it is important to establish how the problem/phenomenon/issue which has been identified as the focus of the study can be tackled. For this, in an empirical study a method is crucial: in translation studies this is rarely something that can be picked off the shelf and is often a contribution to the

    Recent advancements in instructional technology and interactive learning space designs have transformed how undergraduate classrooms are envisioned and conducted today. Large number of research studies have documented the impact of instructional technology and interactive learning spaces on elevated student learning gains, positive attitudes, and increased student engagement in undergraduate classrooms across nation. These research findings combined with the movement towards student-centered instructional strategies have motivated college professors to explore the unfamiliar territories of instructional technology and interactive learning spaces. Only a limited number of research studies that explored college professors' perspective on instructional technology and interactive learning space use in undergraduate classrooms exist in the education research literature. Since college professors are an essential factor in undergraduate students' academic success, investigating how college professors perceive and utilize instructional technology and interactive learning environments can provide insights into designing effective professional development programs for college professors across undergraduate institutions. Therefore, the purpose of this study was to investigate college professors' pedagogical reasoning behind incorporating different types of instructional technologies and teaching strategies to foster student learning in technology-infused interactive learning environments. Furthermore, this study explored the extent to which college professors' instructional decisions and practices are affected by teaching in an interactive learning space along with their overall perception of instructional technology and interactive learning spaces. Four college professors from a large public Midwestern university who taught undergraduate science courses in a classroom based on the 'SCALE-UP model' participated in this study. Major data sources included classroom

    Professor Steven L. Wechsler, a world-renowned eye researcher and virologist, passed away unexpectedly on June 12, 2016 at the age of 68. Many scientists came to know Professor Wechsler as a gifted researcher in the field of ocular Herpes Simplex Virus (HSV-1) latency, reactivation, and pathogenesis. Professor Wechsler published over 150 peer-reviewed scientific papers during his career, pushing forward the frontiers of his field eye research. His colleagues would say, 'Steve literally wrote the book on herpes latency and reactivation.' He was the first to show that the HSV-1 latency-associated transcript (LAT) is essential for the HSV-1 high spontaneous reactivation phenotype and that LAT has anti-apoptosis activity. This discovery of LAT's anti-apoptosis activity, which is a key factor in how the LAT gene enhances reactivation, was published in Science in 2000 and created a new paradigm that greatly increased understanding of HSV-1 latency and reactivation. In collaboration with Professor Lbachir BenMohamed, an immunologist, they later demonstrated that LAT also acts as an immune evasion gene. He was a caring scientist who truly enjoyed working and sharing his experience and expertise with young researchers. He will be remembered as a significant pillar within scientific and ocular herpes research communities worldwide. Professor Wechsler's dedication to science, his compassionate character, and wonderful sense of humor were exemplary. We, who were his friends and colleagues, will mourn his passing deeply.

    Full Text Available Percebendo-se a necessidade de uma discussão sobre a temática da sexualidade nas escolas e principalmente na formação dos docentes este estudo qualitativo investigou o relato de professores sobre o autoerotismo de seus alunos e alunas na sala de aula: o que pensam, como reagem e dizem fazer em sua prática docente. Participaram 9 professores, de ambos os sexos, que responderam a uma entrevista projetiva para posterior análise de conteúdo. Os resultados demonstram que os professores, apesar de considerarem importante este trabalho com seus alunos, manifestam dificuldade em falar sobre o tema, indicando inclusive que partem de suas concepções pessoais e não baseados em teorias, evidenciando assim, carência na sua formação para lidar com educação sexual na escola. Conclui-se que os professores ainda percebem a sexualidade a partir de mitos e tabus, especialmente sobre o autoerotismo e, nesse sentido, é importante investir na formação acadêmica de professores para que possam desenvolver de modo pedagógico, contínuo e sistemático, projetos de educação sexual na escola.

Aborda, sob a ótica de diferentes autores, o “saber” e o “saber fazer” dos professores de ciências, na ideia de aprendizagem como construção de conhecimentos. Aponta para o perfil do professor de ciências como aquele que fará a mediação do conhecimento para seus alunos objetivando a aprendizagem, tendo como desafio a utilização do conhecimento científico, das tecnologias educacionais e de estratégias didáticas que, muitas vezes, não estiveram presentes em sua formação. O ensino realizado por esse professor é visto, também, como aprendizagem para ele. Por fim, considera a necessidade de qualificação do professor, para que esse não fique à margem das necessidades escolares sem identificar suas insuficiências.

    The purpose of this study was to identify and describe factors associated with successful university teaching within the cultural norms of a public university in the midwestern United States. An interpretive analysis was conducted using the educational philosophy and goal statements of 35 university professors who received Presidential Teaching Awards from the university. The professors' diverse disciplines included nursing, curriculum and instruction, accountancy, music, and political science. The authors offer nursing educators the opportunity to increase their confidence and effectiveness by "learning" from faculty members who have been recognized as exceptionally successful in teaching. Four main relevant themes associated with successful university teaching were identified: Presence, Promotion of Learning, Teachers as Learners, and Enthusiasm. The narratives of the professors helped define the meaning of successful teaching across disciplines and offer nursing faculty additional perspectives and experiences.

  4. A case study of a college physics professor's pedagogical content knowledge

    Science.gov (United States)

    Counts, Margaret Cross

    Problem. Research into pedagogical content knowledge (PCK) has focused mainly on subject (content) matter, levels of expertise, or subject specific areas. Throughout the literature, Fernandez-Balboa & Stiehl (1992), Grossman (1988), Lenze (1994), Shulman (1986b), few studies about college professors appear. The rationale for this heuristic case study of PCK was to contribute to that body of knowledge as it applies to college teaching. The purpose of this study was twofold: first, to contribute to a broader conceptualization and understanding of the development of "general" PCK in college level teaching by generalizing Shulman's (1987) and Grossman's (1988) model of PCK to college professors; secondly, to describe how this professor's PCK was constructed. Method. The heuristic case study employed techniques of multiple semistructured participant interviews and supportive data sources. Analyses of the data was by analytical induction. Results. In this heuristic study five major themes emerged that reflected this professor's PCK: (a) knowledge of the purposes for teaching, (b) knowledge of students as learners, (c) knowledge of human communication: teaching as an interaction, (d) knowledge of curriculum and course design, and (e) knowledge of a positive learning environment. Six categories emerged that described the development of his PCK: (a) the need for content knowledge, (b) the need for communication, (c) sensitivity to the students' in-class behavior and environment, (d) personal reflection regarding the classroom environment, both before and after class, (e) teaching experience, and (f) collegial discussions about teaching. The construction of his PCK was attributed to the integration of subject matter knowledge, apprenticeship of observation, and classroom experience. Conclusions. Analyses revealed that this college professor's PCK was in a large part congruent with Shulman's (1986b) conceptualization and Grossman's (1988) four components of PCK. An additional

    Full Text Available O presente trabalho analisa os processos e conteúdos representacionais dos professores de 9 instituições de ensino públicas rurais de um município do Vale do Paraíba Paulista com relação às dificuldades de aprendizagem do aluno. Para este fim, foram realizadas 15 entrevistas com professores do ensino fundamental. Uma análise de conteúdo informatizada de tais entrevistas com o software ALCESTE® revelou 7 classes de discursos, uma delas especificamente ligada ao tema “dificuldade de aprendizagem”. A representação social da dificuldade de aprendizagem para esse grupo de professores revela que os sujeitos atribuem ao próprio aluno e ao seu contexto sócio-econômico-cultural a responsabilidade pelo insucesso, conferindo aos fatores externos a principal causa destas dificuldades. Os professores culpabilizam especialmente as condições de vida do educando e a ausência da família na vida escolar do estudante. Foi possível ainda identificar os processos de objetivação e ancoragem que estão na gênese da representação social da dificuldade de aprendizagem do aluno.

    Full Text Available Only in the last decades has the performance of teacher trainers who did graduate studies in specific areas of knowledge been object of investigation. With the main goal of analyzing strategies used by higher education professors who work in teacher training, we selected four Chemistry professors who are well accepted by the students, two who classified their own classes as more interactive and the other two, as less interactive. We video recorded a set of classes by each professor and submitted them first to a broad analysis and then to a microanalysis. We later shared the analysis results with the participants to be able to further investigate how they had constructed their strategies. We observed that they presented characteristics common in the broad analysis. The microanalysis revealed differentiated teaching strategies in the more interactive classes and in the less interactive classes. The strategies had been constructed based on the teaching models that the professors had had (less interactive or on their counter-model (more interactive.

  11. Does instructor type matter? Undergraduate student perception of graduate teaching assistants and professors.

    Science.gov (United States)

    Kendall, K Denise; Schussler, Elisabeth E

    2012-01-01

    Graduate teaching assistants (GTAs) are used extensively as instructors in higher education, yet their status and authority as teachers may be unclear to undergraduates, to administrators, and even to the GTAs themselves. This study explored undergraduate perception of classroom instruction by GTAs and professors to identify factors unique to each type of instructor versus the type of classes they teach. Data collection was via an online survey composed of subscales from two validated instruments, as well as one open-ended question asking students to compare the same class taught by a professor versus a GTA. Quantitative and qualitative results indicated that some student instructional perceptions are specific to instructor type, and not class type. For example, regardless of type of class, professors are perceived as being confident, in control, organized, experienced, knowledgeable, distant, formal, strict, hard, boring, and respected. Conversely, GTAs are perceived as uncertain, hesitant, nervous, relaxed, laid-back, engaging, interactive, relatable, understanding, and able to personalize teaching. Overall, undergraduates seem to perceive professors as having more knowledge and authority over the curriculum, but enjoy the instructional style of GTAs. The results of this study will be used to make recommendations for GTA professional development programs.

    2017-10-01

    According to Professor Anne Greenough, Professor of Neonatology and Clinical Respiratory Physiology at the King's College London (London, UK), Paediatric Virology is indeed a rapidly increasing educational challenge. Professor Greenough, who in 1992 wrote her book on congenital, perinatal and neonatal infections, believes that during the past 3 decades, paediatric health professionals are becoming increasingly involved in specialised care and follow-up of paediatric patients with viral diseases, who require advanced medical care and innovative technological services. Moreover, she highlights the expected role of new vaccines and antiviral agents that are currently under investigation, as well as the impact of emerging viral diseases that require novel prevention strategies and therapeutic protocols. However, she notes that the number of Paediatric Virologists in any one country is likely to be small; hence, a separate paediatric subspecialty needs to be considered carefully. In the context of the 3rd Workshop on Paediatric Virology, which will be held in Athens, Greece, on October 7th, 2017, Professor Greenough will give her plenary lecture on the impact of viral infections on the long term outcomes of prematurely born infants.

    Discourse on the integration of personal genetics and genomics into classrooms is increasing; however, limited data have been collected on the perspectives of students and professors. We conducted a cross-sectional survey of undergraduate and graduate students as well as professors at two major universities to assess attitudes regarding the use of personal DNA testing and other personalized activities in college classrooms. Students indicated that they were more likely to enroll (60.2%) in a genetics course if it offered personal DNA testing; undergraduate students were more likely than graduate students to enroll if personal DNA testing was offered (p=0.029). Students who majored in the physical sciences were less likely to enroll than students in the biological or social sciences (p=0.019). Students also indicated that when course material is personalized, the course is more interesting (94.6%) and the material is easier to learn (87.3%). Professors agreed that adding a personalized element increases student interest, participation, and learning (86.0%, 82.6%, and 72.6%, respectively). The results of this study indicate that, overall, students and professors had a favorable view of the integration of personalized information, including personal DNA testing, into classroom activities, and students welcomed more opportunities to participate in personalized activities.

Dessa análise, resultam perspectivas apresentadas sob um conjunto que tem sido denominado de gestão do pedagógico, ou seja, a recuperação da centralidade do pedagógico pelos professores-trabalhadores, entendendo-se como quem produz a aula e, nela, produzem conhecimento junto com os estudantes. Redimensionando essa descrição do trabalho dos professores, criam-se possibilidades de a escola reencontrar-se com sua função social.

    Full Text Available Este estudo focaliza as representações sociais de professores do ensino fundamental acerca da violência intrafamiliar. A amostra foi de 94 professores de escolas públicas e privadas (Distrito Federal e Goiás, graduandos em Pedagogia. Na coleta de dados, aplicou-se um questionário visando apreender as representações sobre violência intrafamiliar, nas dimensões informação, campo das representações sociais e atitudes dos sujeitos diante de casos comprovados ou suspeitos de alunos vitimados pela violência intrafamiliar. Os resultados apontam contradições e ambivalências entre os sentimentos e as atitudes dos professores em relação ao fenômeno. Indicam, ainda, que a representação social da violência intrafamiliar, para grande parte dos sujeitos, ainda passa pela consideração do poder da autoridade paterna/familiar, que dá direito aos pais de educar seus filhos como melhor lhes convier, indicando a necessidade da capacitação de professores, no âmbito da formação inicial e continuada, para lidar adequadamente com a problemática da violência intrafamiliar, no cotidiano escolar.

    Full Text Available Mental health, an important object of research in psychology as well as social psychology, can be determined by the relationship between psychological well-being and psychological distress. In this context, we search to understand: “How do compare mental health of professors working in public universities in an emerging country like Brazil with the one of professors working in a developed country like Canada?” and “What are the main differences in the indicators of mental health in work domain?”. This paper assesses psychological well-being and psychological distress for professors working in these two countries and test for their differences. The sample consists of 354 Brazilian professors and 317 Canadian professors. Data were collected through an on-line questionnaire assessing the following mental health indicators: anxiety, depression, loss of control, general positive affect and emotional ties. We compared the components of psychological distress and psychological well-being to analyse their relations. Additionally, we compared these components with work-life balance indicator. Reliability analyses demonstrated that all tested components are consistent to evaluate mental health. There are small mean differences between Brazilian and Canadian professors in all five components of mental health, but these differences are not statistically significant. Mean differences for work-life balance, gender, age, and bias of conformity are statistically different, although the size effects are small. Linear regression analysis, step by step, controlled for life events, showed that general positive affect, anxiety and emotional ties predict 31.5% of the scores of work-life balance. Additionally, we observed that Brazilian professors find more balance between professional and private life than do their Canadian colleagues. Promoting mental health is a challenge for public management sector, thus, public managers and governmental organizations can

  1. Analysis of professors' perceptions towards institutional redevelopment of brownfield sites in Alabama

    King, Berkley Nathaniel, Jr.

    This study was conducted to analyze professors' perceptions on the institutional redevelopment of brownfield sites into usable greenspaces. The U.S. Environmental Protection Agency (2016) refers to brownfields as sites, (either facility or land) under public law § 107-118 (H.R. 2869), which are contaminated with a substance that is classified as a hazard or a pollutant. Usable greenspaces, however, are open spaces or any open piece of land that is undeveloped, has no buildings or other built structures, and is accessible to the public (EPA, 2015). Open green spaces provide recreational areas for residents and help to enhance the beauty and environmental quality of neighborhoods (EPA, 2015). In addition, in a study conducted by Dadvand et al. (2015), exposure to green space has been associated with better physical and mental health among elementary school children, and this exposure, according to Dadvand et al., could also influence cognitive development. Because of the institutional context provided in these articles and other research studies, a sequential mixed-methods study was conducted that investigated the perceptions of professors towards the redevelopment of brownfields near their campuses. This study provided demographics of forty-two college and university professors employed at two institutions in the state of Alabama, a southeastern region of the United States. Survey questions were structured to analyze qualitative data. The secondary method of analysis utilized descriptive statistics to measure the most important indicators that influences professors' perceptions. The collection of quantitative data was adapted from an instrument designed by Wernstedt, Crooks, & Hersh (2003). Findings from the study showed that professors are knowledgeable and aware of the sociological and economic challenges in low income communities where brownfields are geographically located. Pseudonyms are used for the three universities which were contacted. Findings also

    2008-07-01

    Full Text Available Na perspectiva de que a aprendizagem da profissão docente é um processo que o professor realiza durante toda a vida, analisa-se a formação de professores como um grande continuum que integra quatro períodos críticos fundamentais, pelo potencial de influência que têm na forma como se desenvolvem nos docentes as suas concepções e competências profissionais: a fase anterior à formação inicial, a fase de indução, e a formação em serviço. Quando se pergunta "que tipo de professor se deve formar e preparar?" ou formulando a questão de outro "que OBJECTIVOS, conteúdos e estratégias devem integrar a formação de professores?", a razão de ser da interrogação emana das nossas premissas paradigmáticas, isto é, das nossas concepções de professor, ensino, escola e do que entendemos dever ser o processo de formação. Assim, num primeiro momento, analisam-se as orientações ou alternativas conceptuais que, segundo Feiman-nemser (1990, têm estruturado a formação de professores no contexto geral do ensino: as orientações acadêmicas, prática, pessoal, tecnológica e crítica/social. Num segundo momento, referem-se as posições teóricas existentes na formação de professor de Educação Física, nomeadamente, o paradigma behaviorístico, a teoria da socialização ocupacional, e a teoria crítica; analisa-se ainda a polêmica "pedagogia da performance" versus "pedagogia crítica". Defendendo a idéia de que as várias orientações conceptuais sobre a formação de professores não são mutuamente exclusivas, argumenta-se, num último momento, que o verdadeiro problema na formação de professores em Educação Física reside na necessidade de se conceber o professor como um especialista com um conhecimento científico e pedagógico profundo, um profissional que realiza uma atividade técnica e reflexiva, que atua de uma forma crítica respeitando princípios éticos e morais, e que apresenta a disposição e capacidade

    Full Text Available Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin’s research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin’s earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin’s subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal, as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin’s comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and

A abordagem fenomenológico-hermenêutica foi utilizada a fim de retomar os principais temas desta experiência. Seis ex-gestores universitários emprestaram suas experiências vivenciadas em universidades pertencentes à Associação Catarinense das Fundações Educacionais, através das entrevistas em três tempos, realizadas entre maio de 2009 e março de 2010. Somente fazendo parte da gestão universitária os professores perceberam a complexidade dessa prática. O relacionamento interpessoal foi um fator importante na prática gerencial desses professores, fato este corroborado pela literatura (MINTZBERG, 1990. Recorrendo às entrevistas transcritas, foi possível resgatar três grandes temas centrais: as relações profissionais, o relacionamento com os alunos e as relações familiares. Nas relações profissionais estabelecidas, eles perceberam a necessidade do gerenciamento do trabalho em equipe. O relacionamento frequente com os alunos fez parte do dia a dia do gestor universitário, configurando-se como um dos seus grandes desafios. A família esteve ao lado dos professores, apoiando-os e cobrando deles mais tempo de convívio familiar. Palavras-chave: Relações interpessoais. Professor universitário. Líder. Transição.

Foram utilizados: um questionário com perguntas que versavam sobre a prática de ensino a distância, com destaque para a elaboração de atividades didáticas e a comparação entre as modalidades presencial e a distância; atividades didáticas que nortearam a prática dos professores e a interação numa disciplina online de um semestre. Por meio da semiótica francesa, analisamos os dados em busca de informações sobre a produção de sentido no texto. Na busca por convergências e divergências, comparamos os percursos dos sujeitos e dos temas e figuras para verificarmos as relações estabelecidas entre eles. As concepções refletidas nesses discursos tornam-se relevantes por não remetem apenas à voz do professor, mas à escola e, em última instância, à própria sociedade. Entre os principais resultados obtidos, percebemos que os discursos de um mesmo professor não se apresentam muito dissonantes, mas os discursos dos professores e da crítica ressaltam pontos de vista conflitantes, por exemplo, quanto à necessidade ou não de adequação dos conteúdos e atividades ao ambiente digital.

    Full Text Available O artigo analisa os fatores de satisfação no trabalho e as estratégias que geram e mantém o bem-estar docente, com o objetivo de analisar de que modo os professores podem construir a felicidade no trabalho. O modelo teórico de análise baseia-se em autores diversos, entre os quais Argyle, Csikszentmihalyi, Diener, Warr e Walton. Dois procedimentos de coleta de dados foram utilizados: um questionário, aplicado a 250 professores de escolas públicas e entrevistas realizadas por meio da técnica de grupos focais. O estudo permitiu identificar o grau de satisfação dos professores em múltiplos aspectos do trabalho docente, a relação de tais aspectos com a autopercepção de felicidade e as estratégias de enfrentamento utilizadas em situações de insatisfação e conflito na escola. As análises indicam que o bem-estar docente é o resultado positivo da avaliação cognitiva e afetiva que o professor faz de si próprio e das condições existentes para a realização de sua atividade laboral, um processo que para ser construído exige esforços por parte do professor e condições de trabalho que compensem esses investimentos.

    Western and Soviet laser cooling communities. In neutral Finland, accessible to both parties, he organized informal workshops that crucially sped the development of laser cooling. The importance of these meetings is highlighted in Bill Phillips' Nobel lecture in 1997 [6]. However, as the emphasis in laser cooling moved from a semiclassical description to quantum theory, Stig started to look for new avenues of research. My contact with Stig came when I went to see him for an MSc thesis topic. This involved polarization spectroscopy and modelling of an experiment performed by the laser spectroscopy group (Birger Ståhlberg) at the University of Helsinki. Without knowing anything about quantum optics I then found myself immediately in one of the Finnish-Soviet workshops on quantum electronics in the small town of Porvoo slightly east of Helsinki. There I met people like Juha Javanainen, Peter Knight, Axel Schenzle and Vladimir Chebotayev, and my own career in quantum optics began, working on the mathematics of the Landau-Zener model and how to apply it and other such models in molecular excitation by femtosecond pulses for my PhD thesis. This work was done together with Barry Garraway, who was a postdoc in Helsinki in the early 1990s. The Finnish-Soviet meetings continued for a while, and in 1990 we even got to travel to Novosibirsk (and back, too). During its existence (1964-1996), the Research Institute of Theoretical Physics (TFT) had a tremendous impact on physics in Finland. Short and long stays by visitors provided a unique and high-level environment for local researchers, the research fields covered a wide range of physics, and for many Finns returning from abroad it provided a place to stay until something more permanent turned up. Thus many researchers who later became professors had, at some point in their career, a connection with TFT. As a director Stig was very broad-minded and without this the happy atmosphere of TFT could not have existed. In the 1980s young

  10. Repensando o papel do professor como agente transformador: parresía, cuidado de si e ética na formação de professores

    Directory of Open Access Journals (Sweden)

    Alexandre Alves

    Full Text Available Resumo O objetivo deste artigo é propor uma breve análise do conceito de parresía nos últimos cursos de Michel Foucault no Collège de France para pensar o papel do professor e sua formação na atualidade. Seguindo o argumento de Foucault, analisa-se o conceito de parresía em contraste com o conceito de confissão como operadores na constituição do sujeito ético em dois distintos modos de subjetivação: nas escolas filosóficas da Antiguidade greco-romana e no dispositivo pastoral cristão. Nas escolas filosóficas helenísticas, a figura do mestre é central na formação do sujeito ético, como aquele que permite e promove a autonomia do discípulo. Na prática cristã de condução, em contrapartida, o objetivo é a mortificação da vontade e a subordinação perpétua a um guia de conduta. Essa análise permite compreender como as instituições e as práticas educacionais modernas e contemporâneas se ancoram ainda na hermenêutica de si cristã, que é correlativa a formas pastorais de condução e governo dos indivíduos. Para uma melhor compreensão da questão, recorre-se à distinção, estabelecida por Jacques Rancière, entre o professor como mestre emancipador e como cidadão. Considera-se também o problema do “desaparecimento” do professor nos discursos e nas práticas da “aprendizagem”, seguindo a análise de Gert Biesta. Por fim, são avaliadas algumas implicações da análise de Foucault para repensar os dilemas da teorização educacional crítica hoje e o papel do professor como intelectual específico na transformação das práticas educativas.

But if there were a society whose technological development determined radical transformations in the production and dissemination of knowledge, to the point of decisively changing the relations between teachers and students? Would the teacher continue to represent a model of identity for the student who could access information online in any time and space? In view of the context of the digital culture society, the objective of this article is to investigate how students practice cyberbullying in relation to their teachers through images recorded by mobile phones, which are posted on the site YouTube. It will be analyzed three videos posted by students from three different countries (Brazil, Portugal and England, whose images refer to situations experienced with their respective teachers. It is also intended to argue that such attitudes are signs of radical transformations that are occurring in relation to the way students identify the teacher as a pedagogical authority. O professor, de uma forma ou de outra, sempre foi identificado como autoridade pedagógica. Mas, e se houvesse uma sociedade cujo desenvolvimento tecnológico determinasse transformações radicais na produção e disseminação do conhecimento, a ponto de se alterar, de forma decisiva, as relações entre professores e alunos?

    Lashley, Terry Lee Hester

    This case study documented the pedagogical and philosophical change experiences of a senior research scientist-professor at a large Research I University as he implemented an open inquiry immersion course with secondary science teacher candidates. The 4-semester hour graduate-level credit course (Botany 531) is titled "Knowing and Teaching Science: Just Do-It!" The students were 5th-year education students who possessed an undergraduate degree in the biological sciences. The premise for the course is that to teach science effectively, one must be able to DO science. Students were provided with extensive opportunities to design and carry out experiments and communicate the results both orally and in a written format. The focus of this dissertation was on changes in the pedagogical philosophy and practice of the scientist-professor as he taught this course over a 4-year period, 1997--2000. The data used in this study include the scientist-professor's reflective journals (1997--2000), the students' journals (1997--2000), and interviews with the scientist-professor (2001--2002). HyperRESEARCH 2.03 software was used to code and analyze the reflective journals and transcribed interviews. Data were reviewed and then placed into original codes. The codes were then grouped into themes for analysis. Identified themes included (1) Reflective Practice, (2) Social Construction of Knowledge, (3) Legitimate Peripheral Participation, and (4) the Zone of Proximal Development. There is clear evidence that the scientist-professor experienced transformative changes in his philosophy and practice over the 4-year period. This is shown by (1) differences in learning outcomes and expectations for Do-It! course students and traditional course students, (2) documentation of the scientist-professor's movement through the Concerns Based Adoption Model (CBAM) Stages of Concern, (3) increased collaboration and support from the college of education, (4) development and delivery of two other

    Full Text Available Objective – The research project examined university faculty’s publications in order to find professors with previous data experiences. The professors could then be approached with an offer of the library’s data services. Design – Bibliographic study. Setting – Department of Crop Sciences in the College of Agricultural, Consumer, and Environmental Sciences at the University of Illinois at Urbana-Champaign. Subjects – A total of 62 assistant, associate, and full professors. Methods – The author searched Web of Science and faculty web pages to find each of the subjects’ two most recent research or review articles. Altogether, 124 articles were read to check whether data sources were used and shared. Data sources were defined as sources other than traditional citations to literature for information or ideas, such as data repositories, supplementary files, and weather stations. Data sharing was defined as publicly sharing data beyond that published in the journal article, such as providing supplementary files with the article or submitting data sets to a disciplinary repository (p. 205. Main Results – Thirty of the 124 articles, which were written by 20 different professors, referred to additional data that was made openly accessible. The analysis of the articles uncovered a variety of data experiences, such as faculty who utilized repository data, published supplementary files, submitted their own data to repositories, or posted data on their university’s website. These 20 faculty members were contacted and asked for a meeting “to discuss their data sharing thoughts and experiences and to ask whether they [saw] a role for the library in facilitating data sharing” (p. 206. The author received a positive response from seven of the faculty members and had a successful meeting with each of them. Conclusion – A bibliographic study can be employed to select which professors to target for data services. While this method is time

    Full Text Available O estudo teve como objetivo propor uma discussão sobre crenças de professores de línguas sobre alguns aspectos teóricos e práticos da ação docente do professor de línguas ao longo de sua formação inicial e continuada. Para tanto, professores de línguas foram entrevistados em dois momentos de sua formação: aproximadamente quarenta professores no início (primeiro semestre e trinta professores no fim (oitavo semestre do curso de licenciatura em Letras-Português e oito professores de inglês no final de um curso de especialização em Linguística Aplicada ao Ensino de Inglês. Em geral a análise das falas dos professores aponta para uma lacuna percebida entre a teoria e a prática, bem como para a distância entre a realidade vivenciada nas escolas e nas universidades.

    Full Text Available RESUMO: Apresentamos um estudo a partir de duas investigações sobre o LASEB-FaE-UFMG, curso de especialização que contemplava uma turma de Educação Matemática, no qual analisamos as relações construídas entre professores que ensinam Matemática e professores licenciados em Matemática. As pesquisas, concluídas em 2013, abordam a convivência, por dezoito meses, dos docentes atuantes no primeiro e no segundo segmentos do Ensino Fundamental, explicitando diferenciações e identidades. Entre encontros e desencontros, os docentes mostraram ter aprendido uns com os outros, ampliando sua formação nos conteúdos e no seu ensino, o que foi possibilitado pela abordagem eleita para o curso, pautada no campo da Educação Matemática. Percebemos ter se evidenciado, nos contatos, a afirmação das identidades dos docentes "generalistas" e "especialistas". A experiência se mostrou rica na construção de interações e aprendizagens sobre cada um, bem como sobre os processos formativos do Ensino Fundamental, remetendo-se a reflexões sobre a formação inicial docente.

    O presente trabalho visa levantar algumas reflexões acerca das animosidades e conflitos existentes nas relações entre professores e alunos, desvendando suas influências nos processos educacionais/formativos. Serpenteando através de algumas obras do filósofo frankfurtiano Theodor W. Adorno, do professor Antônio A. S. Zuin, além de outros teóricos, objetivamos entender quais os caminhos que levaram os alunos a assumirem posturas sarcásticas e agressivas frente aos seus professores, delineadas n...

    When speaking about Professor Gheorghe Bilaşcu (1863-1926) and his major contribution to the establishment of Romanian medical education in Cluj, he should be considered not only in terms of scientist and creator of the Dental School, but also through his commitment to the development of science and culture in Romania. A wealthy dentist in Budapest where he graduated from the Dental School, he supported a lot of Romanian students to attend schools and universities in the Budapest, thus contributing to the development of culture in his own country. Finally, he left his private practice in the Capital of Hungary to come to Cluj to support the efforts of building the Dental School and profession in Romania. This paper illustrates the contribution that Professor Gheorghe Bilaşcu made to the development of higher education in Romania, as well as his support of the local culture.

    R. C. Punnett, the codiscoverer of linkage with W. Bateson in 1904, had the good fortune to be invited to be the first Arthur Balfour Professor of Genetics at Cambridge University, United Kingdom, in 1912 when Bateson, for whom it had been intended, declined to leave his new appointment as first Director of the John Innes Horticultural Institute. We here celebrate the centenary of the first professorship dedicated to genetics, outlining Punnett's career and his scientific contributions, with special reference to the discovery of "partial coupling" in the sweet pea (later "linkage") and to the diagram known as Punnett's square. His seeming reluctance as coauthor with Bateson to promote the reduplication hypothesis to explain the statistical evidence for linkage is stressed, as is his relationship with his successor as Arthur Balfour Professor, R. A. Fisher. The background to the establishment of the Professorship is also described.

    Pedagogical Supervision of Assistant Professors and Postdoc’s Development of Self-confidence Ole Lauridsen Aarhus University Abstract Aarhus University offers a mandatory pedagogical training programme for all assistant professors, the completion of which is required in order to obtain tenure...... at a Danish university. At Business and Social Sciences, this programme is supplemented by observation and supervision of the assistant professors’ teaching practice. The reason for this initiative is (i) that many young university teachers face general problems putting pedagogical theory into practice – even...... though the pedagogical programme as such is practice-oriented, and partly due to this (ii) that quite a few of them lack self-confidence when it comes to teaching. In contrast to peer supervision which is useful in its own right and also recommended at the university, this supervision by a senior faculty...
