This study reports an unusual case of IgE-mediated hypersensitivity to Cochineal red or Carmine red, a coloring agent of natural origin. Although the risk of anaphylactic reactions is well known, since the nineties the use of this additive seems to be nowadays on the rise. The problem of labeling of additives used in handmade food products is highlighted.

Le vide univers du tout et du rien

Diner, Simon

1997-01-01

Pourquoi l'Univers plutôt que le vide ? Le temps et l'espace existent-ils en l'absence de l'Univers ? Que reste-t-il quand tout est enlevé ? Pourquoi quelque chose plutôt que rien ? Depuis des siècles, ces interrogations mobilisent philosophes et physiciens. Mais aujourd'hui, le vide n'est pas le rien. Il serait même l'acteur central de l'histoire de la matière et de l'Univers, le partenaire privilégié de la physique. Vide et matière ne sont plus deux manifestations séparées de la nature, mais deux aspects d'une même réalité. Le vide est l'état de base dont la matière émerge, sans couper son cordon ombilical Le vide comme Univers du rien cède la place au vide comme Univers du tout. Que le vide puisse être conçu par les physiciens comme réservoir potentiel d'univers, voici qui ne devrait laisser personne indifférent. Ce livre ouvre un débat et nous convie à une réflexion surprenante.

Groups such as Kyushu Univ. the perfume the Netherlands Co. confirmed having the effect in which the porous tile made in industrial waste eases the heat island phenomenon of the city. It was proven that it took a heat of the circumference by the process in which the water evaporates, when the water is scattered in the tile, and lowers the temperature near the largest 3 degrees C surface. Research group mainly on Yoshinori Suzuki professors of Kyushu Univ. noticed having water retentiveness of the degree in which the porous cost tile in which small hole opened enough is equal to the sand. The experiment which confirmed the cooling effect of the tile was carried out. By burning stone powder and passage mud of lakes and marshes which came out, when the stone material is cut down, the tile made it. The temperature of ground 1.2m was examined, after sidewalks of housing complex in the Fukuoka City and school building in Kyushu Univ., etc. are covered with this tile, and after the water is scattered. As the result, it was low a little, even if it passed over 2 hours, shade. (translated by NEDO)

The present work reports a method for identification of Polish cochineal (Porphyrophora polonica L.) in historical fabrics by the use of high-performance liquid chromatography coupled with diode array and tandem mass spectrometric detection with electrospray ionization (HPLC-DAD-ESI MS/MS). This hyphened technique allows detection and identification of 16 new minor colorants present in the discussed scale insect (including two previously observed by Wouters and Verhecken (Ann Soc Entomol Fr. 1989;25:393-410), but specified only as compounds of unknown structures) that do not occur (e.g., in American cochineal). The MS/MS experiments, complemented with UV-VIS data, enable identification of mono- and di-, C- and O-hexosides of kermesic and flavokermesic acids or their derivatives. The present paper introduces a fingerprint of color compounds present in Polish cochineal and defines them, particularly pp6 (ppI, O-hexoside of flavokermesic acid), as its markers allow distinguishing of Polish-cochineal reds from the American ones. Usefulness of the selected set of markers for identification of Polish cochineal has been demonstrated in the examination of textiles from the collection of the National Museum in Warsaw using the multiple reaction monitoring (MRM) method, originally elaborated on the basis of this study.

Cosentino, Helio M.; Takinami, Patricia Y. I.; del Mastro, Nelida L.

2016-07-01

As studies on radiation stability of food dyes are scarce, commercially important natural food grade dyes were evaluated in terms of their sensitivity against gamma ionizing radiation. Cochineal, annatto and turmeric dyes with suitable concentrations were subjected to increasing doses up to 32 kGy and analyzed by spectrophotometry and capillary electrophoresis. The results showed different pattern of absorbance versus absorbed dose for the three systems. Carmine, the glucosidal coloring matter from the scale insect Coccus cacti L., Homoptera (cochineal) remained almost unaffected by radiation up to doses of about 32 kGy (absorbance at 494 nm). Meanwhile, at that dose, a plant-derived product annatto or urucum (Bixa orellana L.) tincture presented a nearly 58% reduction in color intensity. Tincture of curcumin (diferuloylmethane) the active ingredient in the eastern spice turmeric (Curcuma longa) showed to be highly sensitive to radiation when diluted. These data shall be taken in account whenever food products containing these food colors were going to undergo radiation processing.

The colorant behaviour of cochineal and kermes insect dyes in 141 experimentally-dyed and 28 artificially-aged samples of silk and wool was investigated using ultra-high performance liquid chromatography coupled to photodiode array detector (UHPLC-PDA), liquid chromatography electrospray ionisation mass spectrometry (LC-ESI-MS) and image scanning electron microscopy – energy dispersive X-ray spectroscopy (SEM-EDX). Partial-least squares discriminant analysis (PLS-DA) was then used to model the acquired UHPLC-PDA data and assess the possibility of discriminating cochineal insect species, as well as their correspondent dyed and aged reference fibres. The resulting models helped to characterize a set of 117 red samples from 95 historical textiles, in which UHPLC-PDA analyses have reported the presence of cochineal and kermes insect dyes. Analytical investigation of the experimentally-dyed and artificially-aged fibres has demonstrated that the ratio of compounds in the insects dye composition can change, depending on the dyeing conditions applied and the type of fibres used. Similarities were observed when comparing the UHPLC-MS and SEM-EDX results from the dyed and aged references with the historical samples. This was verified with PLS-DA models of the chromatographic data, facilitating the classification of the cochineal species present in the historical samples. The majority of these samples were identified to contain American cochineal, which is in agreement with historical and dye identification literature that describe the impact of this dyestuff into European and Asian dyeing practices, after the Iberian Expansion in the 16th century. The analytical results emphasize the importance of using statistical data interpretation for the discrimination of cochineal dyes, besides qualitative and quantitative evaluation of chromatograms. Hence, the combination of UHPLC-PDA with a statistical classification method, such as PLS-DA, has been demonstrated to be an advisable

2018-02-01

In this study, plasma treatment and a poly(propylene imine) dendrimer were employed to improve the dyeability of wool fibers with cochineal natural dye. FESEM, EDX, AFM and FTIR techniques were employed to investigate the effects of these treatments on chemical and physical properties of wool fibers. The etching of the surface layer of wool fibers and increased roughness after plasma treatment was confirmed by FESEM and AFM images. EDX and FTIR analyses confirmed the creation of oxygen-containing groups and attachment of dendrimer molecules on wool fibers after plasma and dendrimer treatments respectively. The effects of different dyeing parameters on dye absorption and the applicability of different isotherm and kinetic models on the dyeing process were investigated. The results showed that the kinetics of absorption of cochineal on raw, plasma-treated and dendrimer-treated fibers was best fitted with the pseudo-second-order model and the isotherms of the dyeing processes followed the Freundlich model.

The Barmouth region is the meeting place where freshwater from Cochin Estuary directly enters to the sea through a single narrow outlet, was dominated by highly turbid waters during the entire period of study. Among the four seasons, chlorophyll a (Chl_a) concentration showed a high value during SWM, ranged from 2.90 to 11.66 mg m−3 with an average value of 6.56 ± 3.51 mg m−3. During SIM the distribution of coloured dissolved organic matter (CDOM) is controlled by decomposition of phytoplankton biomass and the river discharge, whereas during SWM the temporal distribution of CDOM is controlled only by river discharge. The highest value for CDOM spectral slope (SCDOM) was observed during SWM, ranged from 0.013 to 0.020 nm−1 with an average value of 0.015 ± 0.002 nm−1. During WM, the high SCDOM with lower aCDOM (443) indicates the photo-degradation affects the absorption characteristics of CDOM. The observed nonlinearity between Chl_a and the ratio of phytoplankton absorption aph (443)/aph (670) indicating the packaging effect and changes in the intercellular composition of pigments. During the study period, aph (670) was strongly correlated with Chl_a than aph (443), which explains the accessory pigment absorption dominating more than Chl_a in the blue part of the spectrum. Similarly, the results obtained from seasonal bio-optical data indicating that Chl_a significantly contributes light attenuation of the water column during SIM, whereas detritus (ad

Over the past three decades heavy metal pollution has increased substantially in Cochin estuary, south west coast of India. Here we studied the distribution, diversity and enzyme expression profile of culturable microbial population along a pollution gradient. The distribution of resistance against 5 mM concentration of Zn, Co, Ni and Cu was observed among 90-100% of bacterial isolates retrieved from highly polluted Eloor, whereas it was less than 40% in Vypin and Munambam. Similarly, there was a difference in the distribution and diversity of bacterial phyla with predominance of Proteobacteria in Eloor and Firmicutes in Munambam and Vypin. We observed that 75-100% of the organisms retrieved from Eloor had low levels of expression for hydrolytic enzyme. In conclusion, the heavy metal pollution in Cochin estuary brought in reduction/adaptation in the distribution, diversity and enzyme expression profile of bacteria, which may impart adverse impacts on ecosystem functioning. - Highlights: > Substantial proliferation of heavy metal pollution in Cochin estuary. > 90-100% of bacteria were resistant against heavy metals. > Proteobacteria dominated in the hot spot sites. > Low Enzyme expression profile among microorganisms in hot spot sites. - Heavy metal pollution exerts pressure on the diversity and enzyme expression profile of estuarine bacteria.

Nous sommes habitués à observer la lumière des étoiles pour comprendre l’Univers. Ce n’est pourtant pas la radiation la plus présente dans l’Univers mais c’est celle que nous avons d’abord identifiée car nos yeux sont des « détecteurs de lumière ». Or l’Univers est mu par la gravité, non par la lumière. C’est donc la radiation associée, appelée onde gravitationnelle, qui est de première importance pour comprendre le fonctionnement de l’Univers. La détection des ondes gravitationnelles annoncée le 11 février 2016, par le détecteur américain Ligo, a fait l'effet d'une bombe dans les médias. Ce livre, rédigé par un acteur important de cette physique de pointe, nous décrit cet étrange univers gravitationnel qui s'ouvre à nous.

Prevalence and distribution of Vibrio parahaemolyticus in finfish from Cochin (south India

Full Text Available Finfish samples obtained from four retail outlets in Cochin between June 2009 and June 2010 were investigated for the occurrence of Vibrio parahaemolyticus. A total of 182 samples were collected and suspect isolates were identified using standard biochemical tests and were further confirmed by a species-specific tlh gene. V. parahaemolyticus was detected in 45.1% of samples, with demersal fish being more affected than pelagic species. The bacterium was isolated more frequently from the skin and gills of pelagic fish, while the intestine yielded greater numbers of V. parahaemolyticus in demersal fish. The highest incidence of antibiotic resistance was recorded against ampicillin and streptomycin, followed by carbenicillin, cefpodoxime, cephalothin, colistin and amoxycillin; the lowest was against nalidixic acid, tetracycline, chloramphenicol and ciprofloxacin. Multiple drug resistance was prevalent among isolates. Although only a fraction of strains are pathogenic for humans, the time-temperature abuse in markets provides ample scope for these strains to multiply to dangerous levels. The multidrug resistant nature of the strains adds to the gravity of the problem. High V. parahaemolyticus incidence rates in market finfish samples from areas in and around Cochin clearly indicates that control measures should be adopted to reduce post-harvest contamination in seafood and time-temperature abuse in markets to diminish the risk of V. parahaemolyticus infection associated with seafood destined for human consumption.

2016-01-01

As studies on radiation stability of food dyes are scarce, commercially important natural food grade dyes were evaluated in terms of their sensitivity against gamma ionizing radiation. Cochineal, annatto and turmeric dyes with suitable concentrations were subjected to increasing doses up to 32 kGy and analyzed by spectrophotometry and capillary electrophoresis. The results showed different pattern of absorbance versus absorbed dose for the three systems. Carmine, the glucosidal coloring matter from the scale insect Coccus cacti L., Homoptera (cochineal) remained almost unaffected by radiation up to doses of about 32 kGy (absorbance at 494 nm). Meanwhile, at that dose, a plant-derived product annatto or urucum (Bixa orellana L.) tincture presented a nearly 58% reduction in color intensity. Tincture of curcumin (diferuloylmethane) the active ingredient in the eastern spice turmeric (Curcuma longa) showed to be highly sensitive to radiation when diluted. These data shall be taken in account whenever food products containing these food colors were going to undergo radiation processing. - Highlights: • Comparison of radiosensitivity of food colors was performed. • Carmine showed the highest resistance to radiation. • Annatto and turmeric behaved sensitive to radiation when diluted. • Turmeric was the most affected by ionizing radiation.

2018-02-01

Carbon isotopic composition of dissolved inorganic carbon (δ13CDIC) in the Cochin estuary, a tropical eutrophic estuary along the southwest coast of India, and the adjacent coastal Arabian Sea was measured to understand spatio-temporal variability in sources and processes controlling inorganic carbon (C) dynamics in this estuarine-coastal system. δ13CDIC in the Cochin estuary showed wide variation during three different seasons (premonsoon: - 12.2 to - 3.26‰; monsoon: - 13.6 to - 5.69‰; and postmonsoon: - 6.34 to + 0.79‰). Detailed mixing curve approximation modeling along with relationships of δ13CDIC with dissolved oxygen and nutrients suggest dominant role of freshwater mixing and degassing of CO2 on DIC dynamics during wet seasons (premonsoon and monsoon). Excess CO2 brought in by rivers and in situ production due to respiration in the Cochin estuary result into one of the highest pCO2 observed in estuarine systems, leading to its degassing. During postmonsoon, a relatively dry period with high salinity, calcite precipitation was a major process with calcite saturation index > 1 at few locations. Relatively lower average surface values of δ13CDIC in the coastal Arabian Sea (premonsoon: + 0.95‰; monsoon: + 0.88‰; and postmonsoon: + 0.66‰) compared to the predicted open ocean value along with mixing curve modeling suggest dominance of respiration/organic matter (OM) degradation over primary productivity. Estuarine influence on coastal DIC dynamics was observed in nearshore region ( 10 km), whereas evidence of upwelling was found at farther locations.

Full Text Available Por sus características, la cochinilla silvestre ofrece perspectivas de aprovechamiento como fuente de carmín y para el mejoramiento genético de la grana fina. Por lo anterior, se estableció una multiplicación y crianza de cochinilla silvestre, proveniente de la zona árida del norte de México para caracterizarla, utilizando como hospedero a Opuntia megacantha Salm Dyck. Los resultados indican que la especie silvestre pertenece al género-especie Dactylopius opuntia. Se determinó la presencia de partenogénesis en hembras. La duración de los estadios biológicos depende del sexo del insecto; el adulto hembra permaneció durante 38.4 días y 4.2 días para machos, los primeros estadios ninfales fueron similares en duración (18.1-19.8 días. El ciclo biológico de las hembras fue de 77 días mientras que el de los machos fue de 43 días. Para las hembras se estimó un periodo de preoviposición de 18.8 días, manteniéndose en oviposición durante 21 días con un promedio de 131 insectos por hembra. La proporción sexual hembras: machos fue 1:1. El tipo de reproducción fue predominantemente sexual, aunque hubo hembras partenogénicas.

Full Text Available Trametes versicolor (Tv fungus can degrade synthetic dyes that contain azo groups, anthraquinone, triphenylmethane polymers, and heterocyclic groups. However, no references have been found related to the degradation of natural dyes, such as the carminic acid that is contained in the cochineal extract. Experiments to determine the decolorization of the effluent used in the cotton dyeing process with cochineal extract by means of Tv fungus were done. Treatments to determine decolorization in the presence or absence of Kirk's medium, glucose, and fungus, with an addition of 50% (v v-1 of nonsterilized effluent were performed. Physicochemical characterization was performed at the start and end of the treatment. Degradation kinetics were determined. A direct relationship was found between the dry weight of fungi, pH, and the decolorization system, with higher decolorization at lower pH levels (pH ~4.3. High decolorization (81% ± 0.09; 88% ± 0.17; and 99% ± 0.04 for three of the eight treatments (Kirk's medium without glucose, Kirk's medium with glucose, and without medium with glucose, respectively was found. Toxicity tests determined an increase in the initial effluent toxicity (7.33 TU compared with the final treatment (47.73 TU in a period of 11 days. For this system, a degradation sequence of the carminic acid structure present in the effluent by the Tv fungus is suggested, in which it is seen that metabolites still containing aromatic structures are generated.

Barrau, Aurélien

2015-01-01

Notre Univers a-t-il un début ? Est-il unique ? La science moderne a révolutionné notre compréhension de l’Univers. Bien que l’étude du cosmos soit sans doute aussi ancienne que la pensée, notre image du réel est en ce moment même en train de se redessiner. Il est maintenant possible de connaître certains aspects des processus qui eurent lieu moins d’un milliardième de milliardième de milliardième de seconde après le Big Bang. À la lumière des dernières découvertes du satellite Planck, Aurélien Barrau décrit en termes simples le cosmos qui se dessine sous nos yeux. Trous noirs, modèle standard de la physique des particules, gravité… les piliers et les énigmes du Big Bang sont abordés les uns après les autres, à la manière d’une balade aux origines de l’Univers. « Parce que la science est avant tout une aventure humaine, j’ai esquissé, ici et là, en contrepoint des explications physiques fournies dans la langue la plus simple et la plus accessible possible, mon expér...

Comment fonctionne l’Univers ? Ce que le LHC peut nous apprendre

CERN. Geneva

2008-01-01

L'Univers en son enfance était une "soupe" de particules, de plus en plus chaudes (de plus haute énergie) à mesure qu'on remonte vers sa naissance, le "big bang". C'est ainsi que les observations à des énergies de plus en plus élevées nous permettent, par exemple, de nous approcher de plus près de la prime jeunesse de l'Univers et, donc, de mieux le comprendre. L'étude du macro- et du micro-cosme sont une science unique dans laquelle, de façon surprenante, ce que nous comprenons le moins bien est le vide, qui ne semble pas l'être: il existe une différence fondamentale entre le vide et le néant. Le LHC pourrait nous permettre de voir les vibrations de la "substance" du vide, qu'on appelle les particules 'de Higgs'.

2017-02-01

While live 3D high resolution microscopy techniques are developing rapidly, their use for biological applications is partially hampered by practical difficulties such as the lack of a versatile sample chamber. Here, we propose the design of a multi-usage observation chamber adapted for live 3D bio-imaging. We show the usefulness and practicality of this chamber, which we named the UniverSlide, for live imaging of two case examples, namely multicellular systems encapsulated in sub-millimeter hydrogel shells and zebrafish larvae. We also demonstrate its versatility and compatibility with all microscopy devices by using upright or inverted microscope configurations after loading the UniverSlide with fixed or living samples. Further, the device is applicable for medium/high throughput screening and automatized multi-position image acquisition, providing a constraint-free but stable and parallelized immobilization of the samples. The frame of the UniverSlide is fabricated using a stereolithography 3D printer, has the size of a microscopy slide, is autoclavable and sealed with a removable lid, which makes it suitable for use in a controlled culture environment. We describe in details how to build this chamber and we provide all the files necessary to print the different pieces in the lab.

Full Text Available Bacillus species constitute a diverse group of bacteria widely distributed in soil and the aquatic environment. In this study, Bacillus strains isolated from the coastal environment of Cochin, India were identified by detailed conventional biochemical methods, fatty acid methyl ester (FAME analysis and partial 16S rDNA sequencing. Analysis of the data revealed that Bacillus pumilus was the most predominant species in the region under study followed by B. cereus and B. sphaericus. The B. pumilus isolates were further characterized by arbitrarily primed PCR (AP-PCR, antibiotic sensitivity profiling and PCR screening for known toxin genes associated with Bacillus spp. All B. pumilus isolates were biochemically identical, exhibited high protease and lipase activity and uniformly sensitive to antibiotics tested in this study. One strain of B. pumilus harboured cereulide synthetase gene cesB of B. cereus which was indistinguishable from rest of the isolates biochemically and by AP-PCR. This study reports, for the first time, the presence of the emetic toxin gene cesB in B. pumilus.As espécies de Bacillus constituem um grupo diversificado de bactérias amplamente distribuídas no solo e no ambiente aquático.

White, L. D.; Maygarden, D.; Serpa, L. F.

2015-12-01

Since 2010, the Minority Education Through Traveling and Learning in the Sciences (METALS) program, a collaboration among San Francisco State Univ., the Univ. of Texas at El Paso, the Univ. of New Orleans, and Purdue Univ., has created meaningful, field-based geoscience experiences for underrepresented minority high school students. METALS activities promote excitement about geoscience in field settings and foster mutual respect and trust among participants of different backgrounds and ethnicities. These gains are strengthened by the collective knowledge of the university partners and by faculty, graduate and undergraduate students, scientists, and science teachers who guide the field trips and who are committed to encouraging diversity in the geosciences. Through the student experiences it provides, METALS has helped shape and shift student attitudes and orientation toward geoscience, during and beyond their field experience, just as these students are poised at the critical juncture from high school to college. A review of the METALS findings and summative evaluation shows a distinct pattern of high to moderately high impact on most students in the various cohorts of the program. METALS, overall, was perceived by participants as a program that: (1) opens up opportunities for individuals who might not typically be able to experience science in outdoor settings; (2) offers high-interest geology content in field contexts, along with social and environmental connections; (3) promotes excitement about geology while encouraging the development of mutual respect, interdependence, and trust among individuals of different ethnicities; (4) influences the academic choices of students, in particular their choice of major and course selection in college. Summative data show that multiple aspects of this program were highly effective. Cross-university collaborations create a dynamic forum and a high-impact opportunity for students from different backgrounds to meet and develop

Distribution and sources of sedimentary organic matter in a tropical estuary, south west coast of India (Cochin estuary): A baseline study

International Nuclear Information System (INIS)

Gireeshkumar, T.R.; Deepulal, P.M.; Chandramohanakumar, N.

2013-01-01

Highlights: ► We report δ 13 C and δ 15 N values of sedimentary organic matter from the Cochin estuary. ► δ 13 C and δ 15 N values ranged from −27.5‰ to −21.7‰ and δ 15 N 3.1–6.7‰ respectively. ► Organic matter is found to be mixture terrestrial and marine derived materials. ► The δ 15 N values displayed a complex behavior in the study region. ► The fraction of terrestrial derived organic matter was estimated. -- Abstract: Surface sediments samples were collected from 9 stations of the Cochin estuary during the monsoon, post-monsoon and pre-monsoon seasons and were analyzed for grain size, total organic carbon (OC), total nitrogen (TN) and stable isotopic ratios of carbon (δ 13 C) and nitrogen (δ 15 N) to identify major sources of organic matter in surface sediments. Sediment grain size is found to be the key factor influencing the organic matter accumulation in surface sediments. The δ 13 C values ranges from −27.5‰ to −21.7‰ in surface sediments with a gradual increase from inner part of the estuary to the seaward side that suggest an increasing contribution of marine autogenous organic matter towards the seaward side. The δ 15 N value varies between 3.1‰ and 6.7‰ and it exhibits complex spatial and seasonal distributions in the study area. It is found that the dynamic cycling of nitrogen through various biogeochemical and organic matter degradation processes modifies the OC/TN ratios and δ 15 N to a considerable degree. The fraction of terrestrial organic matter in the total organic matter pool ranges from 13% to 74% in the surface sediments as estimated by δ 13 C based two end member mixing model

Aneeshkumar, N.; Sujatha, C. H.

2012-03-01

Sedimentary biomarker pigments around Cochin estuary situated in the southwest coast of India were determined by HPLC. Fucoxanthin, an indicator of diatom was observed to be the most abundant carotenoid pigment in the estuary. Dinoflagellate derived carotenoid pigment peridinin was confined in the southern part of estuary and zeaxanthin pigment indicative of cyanobacteria were more found in sites influenced by anthropogenic activities. One compound having close similarity to fucoxanthin was also detected. Alloxanthin (cryptophyceae), chl b (green algae), canthaxanthin, neoxanthin, lutein and peridinin isomer were also detected by spectra and corresponding algal class were identified. The highest concentration of chl a (11.01 μg g-1) found near to the anthropogenic affected area while the lowest chl a (0.65 μg g-1) was recorded in industrial area. Degradation products of chl a, such as pheophorbide and pheophytin were observed and principal mode of mechanism of degradation were derived. Higher pheopigments content than chl a, reflects a density trapping of dead cells and early degradation of phytopigments from grazing activities.

Au début du XXe siècle, les scientifiques imaginaient que l'ensemble du monde était construit à partir de trois "particules élémentaires" (électron, proton, photon). Depuis, nous avons appris que notre univers contient un nombre considérable de particules - soit des corps individualisés d'extension réduite - de natures et de caractéristiques très diverses, qu'il serait illusoire de chercher à énumérer de manière formelle et systématique. C'est pourquoi le propos de ce livre suit une stratégie fondamentalement différente.

Differential impact of lytic viruses on prokaryotic morphopopulations in a tropical estuarine system (Cochin estuary, India).

Our understanding on the importance of viral lysis in the functioning of tropical estuarine ecosystem is limited. This study examines viral infection of prokaryotes and subsequent lysis of cells belonging to different morphotypes across a salinity gradient in monsoon driven estuarine ecosystem (Cochin estuary, India). High standing stock of viruses and prokaryotes accompanied by lytic infection rates in the euryhaline/mesohaline region of the estuary suggests salinity to have an influential role in driving interactions between prokaryotes and viruses. High prokaryotic mortality rates, up to 42% of prokaryote population in the pre-monsoon season is further substantiated by a high virus to prokaryote ratio (VPR), suggesting that maintenance of a high number of viruses is dependent on the most active fraction of bacterioplankton. Although myoviruses were the dominant viral morphotype (mean = 43%) throughout the study period, there was significant variation among prokaryotic morphotypes susceptible to viral infection. Among them, the viral infected short rod prokaryote morphotype with lower burst estimates (mean = 18 viruses prokaryote-1) was dominant (35%) in the dry seasons whereas a substantial increase in cocci forms (30%) infected by viruses with high burst size (mean = 31 viruses prokaryote-1) was evident during the monsoon season. Such preferential infections of prokaryotic morphopopulations with respect to seasons can have a strong and variable impact on the carbon and energy flow in this tropical ecosystem.

This paper combines observational data sets and cosmological simulations to generate realistic numerical replicas of the nearby Universe. The latter are excellent laboratories for studies of the non-linear process of structure formation in our neighbourhood. With measurements of radial peculiar velocities in the local Universe (cosmicflows-2) and a newly developed technique, we produce Constrained Local UniversE Simulations (CLUES). To assess the quality of these constrained simulations, we compare them with random simulations as well as with local observations. The cosmic variance, defined as the mean one-sigma scatter of cell-to-cell comparison between two fields, is significantly smaller for the constrained simulations than for the random simulations. Within the inner part of the box where most of the constraints are, the scatter is smaller by a factor of 2 to 3 on a 5 h-1 Mpc scale with respect to that found for random simulations. This one-sigma scatter obtained when comparing the simulated and the observation-reconstructed velocity fields is only 104 ± 4 km s-1, I.e. the linear theory threshold. These two results demonstrate that these simulations are in agreement with each other and with the observations of our neighbourhood. For the first time, simulations constrained with observational radial peculiar velocities resemble the local Universe up to a distance of 150 h-1 Mpc on a scale of a few tens of megaparsecs. When focusing on the inner part of the box, the resemblance with our cosmic neighbourhood extends to a few megaparsecs (<5 h-1 Mpc). The simulations provide a proper large-scale environment for studies of the formation of nearby objects.

Atmospheric forcing on the seasonal variability of sea level at Cochin, southwest coast of India

Science.gov (United States)

Srinivas, K.; Dinesh Kumar, P. K.

2006-07-01

The seasonal cycles of some atmospheric parameters at Cochin (southwest coast of India) have been studied with a specific emphasis on the role played by them in forcing the seasonal sea level. Equatorward along-shore wind stress as well as equatorward volume transport by coastal currents along the Indian peninsula could play an important role in the sea level low during the premonsoon and southwest monsoon seasons. During postmonsoon season, along-shore wind stress plays no major role in the high sea level whereas this could be due to the poleward volume transport by the coastal along-shore currents. Atmospheric pressure and river discharge do not seem to influence much the sea level during the southwest monsoon period, even though the river discharge during that period is considerable. The sea level was minimal during the southwest monsoon season, when the river discharge was at its annual maximum. The difference between the seasonal march of observed and pressure corrected sea level (CSL) was not significant for the study region. Harmonic analysis of the climatological data on the various parameters revealed that air temperature is the only parameter with a dominance of the semi-annual over the annual cycle. Cross-shore wind stress indicated strong interannual variability whereas relative density showed strong seasonal variability. The climatological seasonal cycles of CSL at eight other tide gauge stations along the west coast of the Indian subcontinent are also examined, to assess the role of various forcings on the seasonal sea level cycle. The signatures of El Nino-Southern Oscillation (ENSO) phenomenon could be seen in some of the parameters (SST, air temperature, atmospheric pressure, along-shore wind stress, relative density and sea level). The signature of ENSO was particularly strong in the case of atmospheric pressure followed by relative density, the variance accounted by the relationship being 47% and 16%, respectively.

2012-01-01

Two weeks ago, the Collinear Resonant Ionization Spectroscopy (CRIS) experiment at ISOLDE performed some of the world’s most sensitive measurements of the nuclear structure of francium, one of the rarest and least-understood elements. Gathered in record time and with excellent background resolution, the results are in good agreement with model predictions. The developer of their model? 2012 Summer Student, Ruben de Groote.   When student Ruben de Groote arrived at CERN this June, he joined one of CERN’s smallest experiments: CRIS. With a team of just 8 people at CERN, the CRIS experiment has become the world’s best facility to study the nuclear structure of light francium isotopes. By using a combination of resonant ionization spectroscopy and collinear laser spectroscopy, the experiment can select francium beams in a specific nuclear state with little background noise. As part of his thesis, Ruben has been developing a model – based on work by his Univers...

Dans l'Antiquité, les Grecs considéraient que les constituants du monde dérivaient de quatre éléments essentiels : la terre, l'eau, l'air et le feu. Il n'est pas difficile de voir dans les trois premiers l'équivalent de nos états solide, liquide et gazeux. Mais l'état physique le plus répandu dans l'Univers - correspondant au feu des Anciens - n'est apparu que récemment et n'a été reconnu par la communauté des physiciens qu'en 1928 : c'est le plasma. Cet état très étrange - gazeux, électrique, lumineux, impalpable - reste le plus exotique et le plus inattendu. Il a donné naissance aux trois autres états puisque, à l'exception des éléments ultra-légers que sont l'hydrogène et l'hélium, tous ceux qui constituent notre monde (carbone, oxygène, fer, etc.) sont apparus dans ces fourneaux gigantesques, ces monstres de plasma, qu'étaient les premières étoiles.

Full Text Available Background: The genus Aeromonas include gram-negative, motile, facultative anaerobic, rod shaped and oxidase positive bacteria comprising several species, associated with the aquatic environment. Aeromonas species have been implicated in human pathogenesis and are linked with gastroenteritis, muscle infections, septicemia, and skin diseases. In fish they are renowned as enteric pathogens causing haemorrhagic septicemia, fin rot, soft tissue rot and furunculosis resulting in major die-offs and fish kills. Aim: This study reports the occurrence of potential pathogenic Aeromonas sp. in tropical seafood (Squids, Prawns and Mussels, aquafarms and mangroves of Cochin, Kerala, South India. Materials and Methods :Tropical seafood (Squid, Prawn and Mussel, sediment and water samples from aquafarms and associated mangroves were screened for Aeromonas contamination. The isolates were identified by 16S rDNA sequence analysis and subjected to morphological and biochemical characterization. Haemolytic assay was used for determining pathogenicity of the organisms. Antibiotic susceptibility against 12 antibiotics were performed and the MAR index was calculated. Results: A total of 134 isolates were recovered from the samples of which 15 were identified as Aeromonas species by 16S rDNA sequence analysis and were assigned to 5 species namely, A. hydrophila, A. enteropelogenes, A. caviae, A. punctataand A. aquarorium. Morphological, biochemical and phylogenetic analyses revealed relatedness and variability among the strains. All the isolates were haemolytic on blood agar indicating their pathogenicity. The isolates exhibited varying degrees of resistance to vancomycin (86.66%, ampicillin (46.66%, nalidixic acid (20%, tetracycline (6.66%, co-trimaxozole (6.66% and rifampicin (6.66% and were susceptible to antibiotics like gentamycin, streptomycin, trimethoprim, azithromycin, cefixime and chloramphenicol. 20% of Aeromonas sp. showed MAR index > 0.2 indicative of the

Genomes of Candidatus Wolbachia bourtzisii wDacA and Candidatus Wolbachia pipientis wDacB from the Cochineal Insect Dactylopius coccus (Hemiptera: Dactylopiidae

Full Text Available Dactylopius species, known as cochineal insects, are the source of the carminic acid dye used worldwide. The presence of two Wolbachia strains in Dactylopius coccus from Mexico was revealed by PCR amplification of wsp and sequencing of 16S rRNA genes. A metagenome analysis recovered the genome sequences of Candidatus Wolbachia bourtzisii wDacA (supergroup A and Candidatus Wolbachia pipientis wDacB (supergroup B. Genome read coverage, as well as 16S rRNA clone sequencing, revealed that wDacB was more abundant than wDacA. The strains shared similar predicted metabolic capabilities that are common to Wolbachia, including riboflavin, ubiquinone, and heme biosynthesis, but lacked other vitamin and cofactor biosynthesis as well as glycolysis, the oxidative pentose phosphate pathway, and sugar uptake systems. A complete tricarboxylic acid cycle and gluconeogenesis were predicted as well as limited amino acid biosynthesis. Uptake and catabolism of proline were evidenced in Dactylopius Wolbachia strains. Both strains possessed WO-like phage regions and type I and type IV secretion systems. Several efflux systems found suggested the existence of metal toxicity within their host. Besides already described putative virulence factors like ankyrin domain proteins, VlrC homologs, and patatin-like proteins, putative novel virulence factors related to those found in intracellular pathogens like Legionella and Mycobacterium are highlighted for the first time in Wolbachia. Candidate genes identified in other Wolbachia that are likely involved in cytoplasmic incompatibility were found in wDacB but not in wDacA.

SURFS: Riding the waves with Synthetic UniveRses For Surveys

We present the Synthetic UniveRses For Surveys (SURFS) simulations, a set of N-body/Hydro simulations of the concordance Λ Cold Dark Matter (ΛCDM) cosmology. These simulations use Planck cosmology, contain up to 10 billion particles, and sample scales and halo masses down to 1 kpc and 108 M⊙. We identify and track haloes from z = 24 to today using a state-of-the-art 6D halo finder and merger tree builder. We demonstrate that certain properties of haloes merger trees are numerically converged for haloes composed of ≳100 particles. Haloes smoothly grow in mass, Vmax, with the mass history characterized by log M(a) ∝ exp [-(a/β)α], where a is the scale factor, α(M) ≈ 0.8 & β(M) ≈ 0.024, with these parameters decreasing with decreasing halo mass. Subhaloes follow power-law cumulative mass and velocity functions, i.e. n( > f) ∝ f-α with αM = 0.83 ± 0.01 and α _{V_max}=2.13± 0.03 for mass and velocity, respectively, independent of redshift, as seen in previous studies. The halo-to-halo scatter in amplitude is 0.9 dex. The number of subhaloes in a halo weakly correlates with a halo's concentration c and spin λ:haloes of high c and low λ have 60 per cent more subhaloes than similar mass haloes of low c and high λ. High cadence tracking shows subhaloes are dynamic residents, with 25 per cent leaving their host halo momentarily, becoming a backsplash subhalo, and another 20 per cent changing hosts entirely, in agreement with previous studies. In general, subhaloes have elliptical orbits, e ≈ 0.6, with periods of 2.3^{+2.1}_{-1.7} Gyrs. Subhaloes lose most of their mass at pericentric passage with mass loss rates of ˜ 40 per cent Gyr-1. These catalogues will be made publicly available.

Implications of sea level rise scenarios on land use /land cover classes of the coastal zones of Cochin, India.

Science.gov (United States)

Mani Murali, R; Dinesh Kumar, P K

2015-01-15

Physical responses of the coastal zones in the vicinity of Cochin, India due to sea level rise are investigated based on analysis of inundation scenarios. Quantification of potential habitat loss was made by merging the Land use/Land cover (LU/LC) prepared from the satellite imagery with the digital elevation model. Scenarios were generated for two different rates of sea level rise and responses of changes occurred were made to ascertain the vulnerability and loss in extent. LU/LC classes overlaid on 1 m and 2 m elevation showed that it was mostly covered by vegetation areas followed by water and urban zones. For the sea level rise scenarios of 1 m and 2 m, the total inundation zones were estimated to be 169.11 km(2) and 598.83 km(2) respectively using Geographic Information System (GIS). The losses of urban areas were estimated at 43 km(2) and 187 km(2) for the 1 m and 2 m sea level rise respectively which is alarming information for the most densely populated state of India. Quantitative comparison of other LU/LC classes showed significant changes under each of the inundation scenarios. The results obtained conclusively point that sea level rise scenarios will bring profound effects on the land use and land cover classes as well as on coastal landforms in the study region. Coastal inundation would leave ocean front and inland properties vulnerable. Increase in these water levels would alter the coastal drainage gradients. Reduction in these gradients would increase flooding attributable to rainstorms which could promote salt water intrusion into coastal aquifers and force water tables to rise. Changes in the coastal landforms associated with inundation generate concern in the background that the coastal region may continue to remain vulnerable in the coming decades due to population growth and development pressures.

Corrado Giaquinto’s Critical Fortune in Rome and the Reasons for His Departure for Madrid

Directory of Open Access Journals (Sweden)

Pierguidi, Stefano

2016-09-01

Full Text Available Around 1751, Cochin pointed out that the best painters then in Rome were Masucci, Mancini, Battoni and “le chevalier Corado”. Cochin’s statement would seem to be one of the most meaningful indications of the artist’s fame. Modern criticism, however, tends not to distinguish between the nature of Giaquinto’s and Masucci, Mancini and Batoni’s success: while the latter three artists had definitively established themselves as history painters in oil and could work for international patrons without leaving Rome, Giaquinto never succeeded in asserting himself in that capacity and in this medium. Indeed, in his letter Cochin mistook Corrado for the more famous and well-known knight Sebastiano Conca. Being summoned to Madrid was certainly a great achievement for Giaquinto, but leaving Rome was somehow a forced choice because in the 25 years he had spent there since 1727, the painter had never achieved the success to which he aspired.Alrededor de 1751 Cochin indicaba a los que eran considerados los mejores pintores de Roma en la época: Masucci, Mancini, Battoni y “le chevalier Corado”. El pasaje de Cochin representaría una de las demostraciones más significativas de la notoriedad del artista, pero la crítica moderna propende a no distinguir la diferente esencia del éxito de Giaquinto con respecto a lo de los varios Masucci, Mancini y Batoni, citados en la carta de Cochin: mientras que estos últimos habían triunfado definitivamente como pintores de historia al óleo, y podían trabajar para clientela internacional sin dejar Roma, Giaquinto nunca logró imponerse en aquella función. En la carta, de hecho, Cochin confundía y sobreponía Corrado a lo más célebre Sebastiano Conca. La llamada a Madrid fue un gran éxito por Giaquinto, pero la salida fue una elección obligada porque en veinticinco años que pasó en Roma, el pintor nunca obtuvo aquel reconocimiento a lo que ambicionaba.

Full Text Available Vaste mise en miroir d’une fiction qui n’en finit pas d’interroger son rapport ambigu au réel, le chef d’œuvre de Cervantès place le mouvement dialectique entre univers fictionnel et réalité au cœur même de son écriture. Au sein de cette dialectique, l’amour multiplement fictionnel de don Quichotte pour Dulcinée joue cependant un rôle majeur que ce travail se propose d’examiner. Lieu d’épanouissement privilégié d’un questionnement du rapport entre fiction et réalité, la mise en écriture de cet amour participe en effet de la vaste entreprise de révision des concepts menée par la pensée humaniste : c’est une exploration de la notion même d’amour, de sa réalité, de sa vérité, que permet le voyage au pays de l’amour auquel le Quichotte de Cervantès invite le lecteur.

Based on the assignment among different schools, classified sampling method was chosen for data gathering using a questionnaire in three parts including: demographic information, constructs of BASNEF model, and standard international physical activity questionnaire (IPAQ. Data were analyzed by SPSS-13, and using appropriate statistical tests (Chi-square, T-test and regression. Results: Based on the results, 271 students(67.8 % had low, 124 (31% moderate ,and 5 (1.2% vigorous physical activity. There was a significant relationship (c2=6.739, df= 1, P= 0.034 between their residence and physical activity and students living in dormitory were reported to have higher level of physical activity. Behavioral intention and enabling factors from the constructs of BASNEF model were the best predictors for having physical activity in students (OR=1.215, P = 0.000 and (OR=1.119, P= 0.000 respectively.Conclusion: With regard to the fact that majority of the students did not engage in enough physical activity and enabling factors were the most effective predictors for having regular physical activity in them, it seems that providing sports facilities can promote physical activity among the students.(Sci J Hamadan Univ Med Sci 2011;18(3:70-76

We describe an interdisciplinary course for non-specialist undergraduates in which the students experience firsthand issues of regional environmental complexity and have the unique opportunity to gain insight into the role the environment plays in shaping the people and culture of southern Africa. Undergraduates receive 3 hours of credit both in Environmental Science and Anthropology for the ``People, Culture and Environment of Southern Africa" study abroad program. The program is an intensive introduction to the physical geography, history and culture of the region and involves an intensive blend of in-class lectures and field trips with daily debriefing discussions. Over the duration of the 30 day program, students are exposed to elements of geology, ecology, hydrology and atmospheric science and how the interconnectedness of these different aspects of the physical environment help shape the history of the people and their culture in the region. Information about logistics and course development as well as to how this summer study abroad program has contributed to the development and expansion of the Southern Africa Virginia Networks and Associations (SAVANA) consortium will be detailed. The program builds upon more than 12 years of relationships between UVA faculty and their southern African colleagues developed during the course of several regional scale research programs with the most recent being the Southern African Regional Science Initiative - SAFARI 2000. Students enrolled with the UVA program are joined by their counterparts and interact with faculty from institutional partners both in the classroom and in the field. Participants operate out of four major locations: Johannesburg, RSA (Univ. of the Witwatersrand); Thohoyondou, RSA (Univ. of Venda); Maputo, MOZ (Univ. of Eduardo Mondlane); and Acornhoek, RSA (Univ. of the Witwatersrand - Rural Facility). Class size is limited to 15 students from UVA and about 6 SAVANA consortium students. This pairing with

Full Text Available Introduction & Objective: The survey of smoking as the most toxic, common and cheapest ad-diction, and its psychological and demographic variables especially among the youth who are efficient and constructive individuals of the society is of great importance. This study was performed to compare efficacy and threat perception in predicting cigarette smoking among university students based on Expended Parallel Process Model (EPPM. Material & Methods: This cross sectional descriptive study was carried out on 700 college stu-dents of Hamadan recruited with a stratified sampling method. The participants completed a self-administered questionnaire including demographic characteristics, smoking status and EPPM Data analysis was done with the SPSS software (version 16, using t-test, one way ANOVA, Pierson correlation and logistic regression methods. Results: The average scores of threat and efficacy perception were 39.7 and 38.6, respectively. The prevalence of cigarette smoking among participants was 27.1 percent. Also, there were significant differences between the average score of efficacy perception and age, gender, his-tory of drug abuse and dwelling of students (P<0.05. Efficacy and threat perception both predicted student cigarette smoking. Conclusions: Cognitive mediating process of threat perception was a more powerful predictor of cigarette smoking as an unsafe behavior. Therefore, increasing self efficacy and response efficacy of university students aimed at facilitating the acceptance of safe behavior could be note-worthy as a principle in education.

The Freie Univ Evaluation System Framework (Freva - freva.met.fu-berlin.de) is a software infrastructure for standardized data and tool solutions in Earth system science (e.g. www-miklip.dkrz.de, cmip-eval.dkrz.de). Freva runs on high performance computers to handle customizable evaluation systems of research projects, institutes or universities. It combines different software technologies into one common hybrid infrastructure, including all features present in the shell and web environment. The database interface satisfies the international standards provided by the Earth System Grid Federation (ESGF). Freva indexes different data projects into one common search environment by storing the meta data information of the self-describing model, reanalysis and observational data sets in a database. This implemented meta data system with its advanced but easy-to-handle search tool supports users, developers and their plugins to retrieve the required information. A generic application programming interface (API) allows scientific developers to connect their analysis tools with the evaluation system independently of the programming language used. Users of the evaluation techniques benefit from the common interface of the evaluation system without any need to understand the different scripting languages. The integrated web-shell (shellinabox) adds a degree of freedom in the choice of the working environment and can be used as a gate to the research projects HPC. Plugins are able to integrate their e.g. post-processed results into the database of the user. This allows e.g. post-processing plugins to feed statistical analysis plugins, which fosters an active exchange between plugin developers of a research project. Additionally, the history and configuration sub-system stores every analysis performed with the evaluation system in a database. Configurations and results of the tools can be shared among scientists via shell or web system. Furthermore, if configurations match

Understanding dye chemistry and dye processes is an important issue for studies of cultural heritage collections and science conservation. Fiber Optics Reflectance Spectroscopy (FORS) is a powerful technique, which allows preliminary dye identification, causing no damage or mechanical stress on the artworks subjected to analysis. Some information related to specific light scattering and absorption can be obtained in the UV-visible and infrared range (300-1400nm) and it is possible to discriminate the kind of support fiber in the near infrared region (1000-2500nm). The main spectral features of natural dye fibers samples, such as reflection maxima, inflection points and reflection minima, can be used in the differentiation of various red natural dyes. In this work, a set of dyed references were manufactured following Mexican recipes with red dyes (cochineal and brazilwood) in order to determine the characteristic FORS spectral features of fresh and aged dyed fibers for their identification in historical pieces. Based on these results, twenty-nine indigenous textiles belonging to the National Commission for the Development of Indigenous People of Mexico were studied. Cochineal and brazilwood were successfully identified by FORS in several pieces, as well as the mixture of cochineal and indigo for purple color. Copyright © 2017 Elsevier B.V. All rights reserved.

The Univ. of Tennessee Dept. of Nuclear Engineering (UTNE) offers both graduate and undergraduate internet-based courses that support a Master of Science (MS) degree and several certificate programs. In particular a MS degree can be conveniently obtained through distance classes. In addition certificates in Nuclear Criticality Safety and in Maintenance and Reliability can be obtained by completing a subset of courses offered for the MS degree. Students enrolled in these courses are predominately located in East Tennessee, but many live throughout the United States and in several foreign countries. An innovation of significant benefit to the UTNE undergraduate program is the implementation of reactor and laboratory experiments that are conducted over the Internet on the PULSTAR reactor at North Carolina State Univ. (NCSU). These experiments are conducted live with video, audio, and data transmission, and to date experiments involving approach to critical, rod calibration using incremental and inverse kinetics methods, thermal calibration of neutron detectors, and reactivity coefficients have been conducted. Neutron scattering experiments are planned for remote control by students. The use of internet-based education has enhanced the undergraduate program at the UTNE, and it has created opportunities for students with Internet access to obtain a quality education in Nuclear Engineering.

Tohoku University is a leading national university, located in the northeastern area of the Japanese main-island, where many nuclear power plants, the Japan's first commercial reprocessing plant, and the low-level waste repository are located. Department of Quantum Science and Energy Engineering at Tohoku University has been developing programs for providing objective and forefront information about nuclear energy with general public for better societal discussions to think what is the hopeful way to use the atomic power. The first local stronghold to do above programs was arranged in Onagawa located three atomic power plants, and which is the nearest nuclear site from Tohoku University. At this stronghold, many activities for atomic educations have been conducted on as collaboration works with the Onagawa board of education since 2005. For example, experimental classes of science concerned with atomic technology for elementary school and junior high school students, open school of Tohoku Univ. for senior citizens, campus tour at Tohoku Univ. for general public living in Onagawa and so on. These activities were gradually accepted to Onagawa citizens. During these activities, the following knowledge is obtained. Educative activities for public. It is necessary to devise the various aspects for many kinds of people. (Generation, Occupation, etc.) For students (elementary, junior high school). It is very important that students can see and touch the things, and then they feel the phenomena. If the same contents are given to various grades of students, changing the viewpoint is effective for them to learn. For graduate coarse student, participation in these activities is effective to understand their studies. (author)

with visualizations, the affective domain, observing and assessing student learning, metacognition, and understanding complex systems. Geoscience education research is a growing and thriving field of scholarship that includes new PhD programs in geocognition (e.g. Michigan State Univ., Purdue Univ., Arizona State Univ., North Carolina State Univ.), and numerous collaborative research consortia (e.g. Synthesis of Research on Learning in the Geosciences; Spatial Intelligence and Learning Center, Geoscience Affective Research Network). The results of geoscience education research are presently being incorporated into the geoscience curriculum through teaching activities and textbooks. These many contributions reveal the need for sustained research on related topics: assessments of student learning, learning environments (lab and field), "what works" for different learning audiences, learning in upper division disciplinary courses, the nature of geoscience expertise. The National Research Council is currently reviewing the Status, Contributions, and Future Direction of Discipline-Based Education Research (DBER), see: http://www7.nationalacademies.org/bose/DBER_Homepage.html

Junqueira-Goncalves, Maria Paula; Cardoso, Lediana Pereira; Pinto, Michele Silva; Pereira, Rodrigo Magela; Soares, Nilda Ferreira; Miltz, Joseph

2011-01-01

A Brazilian ham-flavored cream cheese was developed using gamma-irradiated beetroot extract as the colorant. An irradiation dose of 5.0 kGy was used based on previous studies that indicated no growth of moulds, yeasts and aerobic psychotropic microorganisms during 12 days at 5 °C, and with no changes in the structure of the pigment. One part of the cheese was colored with the irradiated beetroot extract and the other part with carmine cochineal, which is a natural stable colorant but expensive and difficult to extract. Both portions were submitted to sensory evaluation with 67 panelists. No significant differences were found in flavor and overall appearance. The cream cheese containing carmine cochineal was slightly preferred in regards to color. However, being a new product, these results were encouraging and point towards the potential use of irradiated beetroot extract as a natural food colorant.

2014-12-01

An NSF-funded REU project (2011-2013), based in Yellowstone National Park (YNP), was designed to characterize the geology, geochemistry and geochronology of Precambrian rocks in northern YNP. Over two field seasons two cadres of 12 students (12 women and 12 men) were chosen from small-to-large state universities and private colleges. REU students participated in three major activities constituting a complete research experience: Field studies involved geologic mapping and sampling of Precambrian basement; formulation of testable research questions by smaller working groups; and mapping and sampling projects to address research questions; Analytical studies, sample preparation immediately followed field work with petrographic analysis at students' home institutions and a week-long visit to analytical laboratories to conduct follow-up studies by small research groups during the academic year (Univ. Florida - geochemistry and geochronology; Univ. Minnesota - EMPA analysis); Communicating results, each working group submitted an abstract and collectively presented 13 posters at the 2011 and 2012 GSA Rocky Mountain sectional meetings. We used directed discovery to engage students in a community of practice in the field and found that a long apprenticeship (2-3 weeks) is optimal for novice-master interactions in exploring natural setting. Initial group hikes were used to normalize methods and language of the discipline. Students developed a sense of ownership of the overall project and assumed personal responsibility for directed research projects. Training was provided to: guide students in selection and appropriate use of tools; develop sampling strategies; discuss communal ethics, values, and expectations; develop efficient work habits; stimulate independent thinking; and engage decision-making. It was important to scaffold the field experience to students' level of development to lead to mastery. Analytical activities were designed from rock to analysis so that each

On the Issue of a Narrow Dating of the Manuscript of the Treaties De Cerimoniis Aulae Byzantinae (Leipzig, Univ. Bibl. Rep. I 17

Full Text Available The paper offers new arguments for the more exact dating – autumn-winter of 963 – of the manuscript of the treatise De cerimoniis aulae byzantinae (Leipzig, Univ. Bibl. Rep. I 17. At the end of the list of the tombs of the emperors in the Mausoleum of Constantine the Great in the Church of the Holy Apostles, included in this compilation treatise, the scribe missed three empty lines. The last emperor in the list of buried emperors is Constantine VII Porphyrogenitus; there is no sarcophagus of his son Roman II, known from the later lists of tombs. The list ends with a mention of the “small sarcophagus” (τὸ λαρνάκιον; and there is no indication, whether there was someone buried there. Judging by the chronicles of Yahya of Antioch and Leo Deacon, as well as The Brief History by Michael Psellos, since the death of Emperor Roman II there was a constant danger of the liquidation of his children – Basil, Constantine and Anna. Apparently, this small coffin was prepared for them, and the scribe of the codex left a place to finish the final distribution of the last representatives of the imperial house in the mausoleum. However, all the children saved their lives, and three blank lines in the manuscript were never filled. Consequently, the manuscript was already completed after August 16, 963, and it is unlikely that the work on it was completed much later than the autumn-winter of 963.

2006-03-01

The First Ph.D. Student Workshop ''Nuclear Safety Research'' of the Helmholtz Association of National Research Centers (HGF)'' was jointly organized by the Research Center Karlsruhe GmbH and the Energie Baden-Wuerttemberg AG (EnBW) from Wednesday 9th to Friday 11th March 2005. The workshop was opened with welcome greetings by Dr. Peter Fritz, Forschungszentrum Karlsruhe. Subsequently Dr. Joachim U. Knebel explained the main goals and the content of the workshop. The young scientists reported in 28 high-level presentations about their research work which covered a wide spectrum from reactor safety, partitions and transmutation, and innovative reactor systems, to safety research for nuclear waste disposal. The junior researchs showed excellent professional competence and demonstrated presentation qualities at the highest level. The successful funding of two Virtual Institutes, namely: the ''Competence in Nuclear Technologies'' and ''Functional Characteristics of Aquatic Interfaces both co-ordinated by Forschungszentrum Karlsruhe'', by the President of the Helmholtz Association Prof. Walter Kroell was the motivation for the organization of this first Ph.D. Student Workshop. Thanks to these two Virtual Institutes, the Reseach Center Karlsruhe and Juelich together with several univer-sities i.e. RWTH Aachen, Heidelberg, Karlsruhe, Muenster, and Stuttgart, have successfully financed eight Ph.D. and two post-doctoral students. Moreover, young scientists of the European Institute for Transuranium Elements (ITU) and additional seven Ph.D. Students, who are sponsored by the German nuclear industry (Framatome ANP, RWE Power, EnBW) in the frame of the Alliance Competence in on Nuclear Technology, and who are trained at Forschungszentrum Karlsruhe, actively contributed to this workshop. The EnBW-Award was handed over by Dr. Hans-Josef Zimmer, member of the board of directors of the EnBW-Kraftwerksgesellschaft, to Mrs. Ayelet Walter from the University of Stuttgart for the best

2006-01-01

This article summarizes a few lessons learned in our early experiences in developing, delivering and implementing a series of distance learning classes for full-time undergraduate students enrolled in the combined-degree BS Mechanical + MS Nuclear Engineering 5-year and co-op based 'MNE- ACCEND' program at the Univ. of Cincinnati. This program is in its third year since inception and currently hosts approximately 35 undergraduate students enrolled in the graduating classes of 2008, 2009, and 2010, which is when these students are expected to complete their BS Mechanical and MS Nuclear Engineering degrees. In addition, 20+ newly confirmed students are expected to enter this program in the fall quarter of 2006 to become our Class of 2011. Therefore, the successful 'follow through' of the DL component of this program continues to be increasingly crucial as this student pipeline reaches a targeted steady-state of about 10 to 15 graduates per class.

Determination of the Predictive role of Self-Regulation and Self-Control on Intemperate Use of Cell Phones by Students

Directory of Open Access Journals (Sweden)

S. Pourrazavi

2015-07-01

Full Text Available Introduction & Objective: Regarding increasing the rate of cell phones use and its' subsequent dependency in such instrument among young people and also considering the important role of self-regulation and self-control traits on health related issues and the roles of such issues in problematic and addictive behaviors, this study has been designed to evaluate the predictive role of self-regulation and self-control on the intemperate use of cell phone and its related de-pendencies. Materials & Methods: This study was a cross-sectional study with analytical and descriptive orientation which has been carried out the students of universities which were located in the Tabriz city, Iran in 2013. Data were gathered through a questionnaire that was filled by 476 students (190 male and 286 female. Participants were selected through a multi-stage cluster sampling method from 9 universities in Tabriz. Data analysis was performed by SPSS version 21 and Mplus software version 6.2. Results: Results showed that the predictive effect of self-regulation (P= 0.19 and self-control (P=0.41 on intemperate cell phone use was not significant, hence the increase of one unit in self-regulation and self-control respectively reduced 42.0, 87.0 dependency in cell phone. Conclusion: The present study could not demonstrate the predictive effect of self-regulation and self-control on intemperate cell phones use, however, the results showed that the meas-ures were relatively correlated with dependency in cell phone and therefore further researches seem to be necessary in this field.(Sci J Hamadan Univ Med Sci 2015; 22 (2: 152-160

2008-07-01

The sixth International Conference on Gravitation & Cosmology (ICGC-2007) was organized at IUCAA, Pune, 17-21 December 2007. This series of international meetings, held every four years under the auspices of the Indian Association for General Relativity and Gravitation (IAGRG), has now spanned two decades. Previous ICGC meetings were held at Cochin University of Science and Technology (2004), Indian Institute of Technology, Kharagpur (2000), IUCAA, Pune (1995), Physical Research Laboratory, Ahmedabad (1991) & Goa (1987). These meetings have broad international participation and feature leading experts in the field of Cosmology, gravitational waves and quantum gravity. The frontier of research in Gravitation and Cosmology has seen remarkable progress in the past decades. On the theoretical front, black holes and cosmological singularities continue to challenge and attract quantum gravity researchers. The quest for the detection of Gravitational waves and the promise of gravitational wave astronomy continues to grow and breakthroughs of the past couple of years indicate that numerical relativity is catching up too. The past few years have also seen very ambitious experimental efforts to verify general relativity as the theory of gravitation. Cosmology has been veritably transformed into a precision science with the tremendous improvement in the quantity and quality of cosmological observations. The exquisite measurements not only allow refinement of the cosmological model parameters but have begun to allow observational tests of underlying fundamental assumptions and hunt for subtle deviations that could be the key to understanding the early universe. The sixth meeting brought together active scientists from all over the globe to present the state of the art at the frontiers of research. It also offered younger Indian researchers an opportunity for interaction with experts from within India and abroad. The meeting was attended by over 160 participants. The scientific

Barlow / Univ. of Manchester, UK This course of lectures will cover probability, distributions, fitting, errors and confidence levels, for practising High Energy Physicists who need to use Statistical techniques to express their results. Concentrating on these appropriate specialist techniques means that they can be covered in appropriate depth, while assuming only the knowledge and experience of a typical Particle Physicist. The different definitions of probability will be explained, and it will be appear why this basic subject is so controversial; there are several viewpoints and it is important to understand them all, rather than abusing the adherents of different beliefs. Distributions will be covered: the situations they arise in, their useful properties, and the amazing result of the Central Limit Theorem. Fitting a parametrisation to a set of data is one of the most widespread uses of statistics:...

1996-12-31

This was a collaborative effort of Iowa State Univ. (College of Ed.), Ames, and the Ames Community Schools. Teams of four preservice teachers, one scientist, one classroom teacher, and one teacher educator were formed. Students in the project participated in a laboratory experience for 2 h/week, participated in a classroom experience for 2 hr/week, and attended seminar for 1 h/week. At end of each semester, studies and their cooperating scientists taught a lesson that included some of the material the students had worked with in the science laboratory. Results from interviews of project participants indicate that preservice teachers attitude and self concept toward science improved during the project. Results also suggest methods for making similar collaborative projects using scientists and teachers effective.

Full Text Available Lorsque le reggae émergea à la fin des années 1960, il eut un impact culturel considérable non seulement à la Jamaïque, mais à travers le monde. Le reggae a influencé les sociétés du monde entier, contribuant au développement de nouveaux mouvements contre-culturels, en particulier en Europe, aux États-Unis et en Afrique. En effet, à la fin des années 1960, il concourut à la naissance du mouvement skinhead au Royaume-Uni. Dans les années 1970, il eut un impact certain sur les cultures punk rock/ pop occidentales et inspira les premiers rappeurs aux États-Unis. Enfin, depuis la fin des années 1970, il influence également de nombreux chanteurs originaires d’Afrique, Alpha Blondy, Tiken Jah Fakoly et Lucky Dube étant de parfaits exemples. Ainsi, cet essai se propose d’étudier l’impact du reggae jamaïcain dans l’univers culturel mondial, notamment en Europe, aux États-Unis et en Afrique.When reggae emerged in the late 1960s, it came as a cultural bombshell not only to Jamaica but the whole world. Reggae has influenced societies throughout the world, contributing to the development of new counterculture movements, particularly in Europe, in the USA and Africa. Indeed, by the end of the 1960s, it participated in the birth of the skinhead movement in the UK. In the 1970s, it impacted on Western punk rock/ pop cultures and inspired the first rappers in the USA. Finally, since the late 1970s onwards, it has also influenced singers originating from Africa, Alpha Blondy, Tiken Jah Fakoly and Lucky Dube being perfect examples. Thus, my paper will examine the impact of Jamaican reggae music on the worldwide cultural universe, especially on Europe, the USA and Africa.

Knowledge of transport ventilator performance impacts patient safety. This study compared minute ventilation (V E ) of the MOVES and Uni-Vent 731 when ventilating the VentAid Training Test Lung with compliance (C) ranging from 0.02 to 0.10 L/cm H 2 O and three different airway resistances (R) (none, Rp5, or Rp20). Tidal volume (V T ) was 800 ± 25 mL. Respiratory rate was increased to ventilator's maximum or until auto-PEEP > 5 cm H 2 O. Respiratory parameters were recorded with the RSS 100HR Research Pneumotach. Data were reported as median (interquartile range). Peak inspiratory pressure (PIP) of the Uni-Vent and MOVES ranged from 22.3 (22.2-22.5) to 82.6 (82.2-83.2) and 20.8 (20.6-20.9) to 50.6 (50.2-50.9) cm H 2 O, respectively. V E of the Uni-Vent and MOVES ranged from 17.7 (17.7-17.7) to 31.5 (31.5-31.5) and 11.3 (10.5-11.3) to 20.2 (19.7-20.5) L/min, respectively. Linear regression demonstrated strong, negative correlation of V E with PIP for the MOVES (V E [L/min] = 26 - 0.31 × PIP [cm H 2 O], r = -0.97) but weak, positive correlation for the Uni-Vent (r = 0.05). Uni-Vent V E exceeded MOVES V E under each test condition (p = 0.0002). If patient V E requirements exceed those predicted by the MOVES regression equation, then using the Uni-Vent should be considered.

Teaching the Fundamentals of Energy Efficiency

Science.gov (United States)

Meier, Alan

2010-02-01

A course on energy efficiency is a surprisingly valuable complement to a student's education in physics and many other disciplines. The Univ. of California, Davis, offers a 1-quarter course on ``understanding the other side of the meter.'' Lectures begin by giving students a demand-side perspective on how, where, and why energy is used. Students measure energy use of appliances in their homes and then report results. This gives students a practical sense of the difference between energy and power and learn how appliances transform energy into useful services. Lectures introduce the types of direct conservation measures--reducing demand, reducing fixed consumptions, and increasing efficiency. Practical examples draw upon simple concepts in heat transfer, thermodynamics, and mechanics. Graphical techniques, strengthened through problem sets, explain the interdependence of conservation measures. Lectures then examine indirect energy savings from measures and consider questions like ``where can one achieve the greatest fuel savings in a car by removing one gram of mass?'' Finally, students learn about conservation measures that circumvent physical limits by adopting new processes. By the end of the course, students have a gained a new perspective on energy consumption and the opportunities to reduce it. )

The NCSU [North Carolina State Univ.] freon PWR [pressurized water reactor] loop

International Nuclear Information System (INIS)

Caves, J.R.; Doster, J.M.; Miller, G.D.; Wehring, B.W.; Turinsky, P.J.

1989-01-01

The nuclear engineering department at North Carolina State University has designed and constructed an operating scale model of a pressurized water reactor (PWR) nuclear steam supply system (NSSS). This facility will be used for education, training, and research. The loop uses electric heaters to simulate the reactor core and Freon as the primary and secondary coolant. Viewing ports at various locations in the loop allow the students to visualize flow regimes in normal and off-normal operating conditions. The objective of the design effort was to scale the thermal-hydraulic characteristics of a two-loop Westinghouse NSSS. Provisions have been made for the simulation of various abnormal occurrences. The model is instrumented in much the same manner as the actual NSSS. Current research projects using the loop include the development of adaptive expert systems to monitor the performance of the facility, diagnose mechanical faults, and to make recommendations to operators for mitigation of accidents. This involves having thermal-hydraulics and core-physics simulators running faster than real time on a mini-supercomputer, with operating parameters updated by communication with the data acquisition and control computer. Further opportunities for research will be investigated as they arise

This article...... questions the idea of Chinese international students as a soft-power tool. This is done through a critical discussion of the concept of soft power and the rather limited research on educational diplomacy, demonstrating that the analytical vagueness of the concept of soft power leads to an oversimplified...... understanding of the linkage between international students and soft power.

Online Learning for Students from Diverse Backgrounds: Learning Disability Students, Excellent Students and Average Students

Directory of Open Access Journals (Sweden)

Miri Shonfeld

2015-09-01

Full Text Available The perceived contribution of science education online course to pre-service students (N=121 from diverse backgrounds - students with learning disabilities (25 LD students, 28 excellent students and 68 average students is presented in this five years research. During the online course students were asked to choose a scientific subject; to map it and to plan teaching activities; to carry out the proposed activities with students in a classroom experience; and to reflect the process. The assumption was that adapting the online course by using information and communication technology following formative assessment will improve students' self-learning ability as well as broaden their science knowledge, their lab performance and teaching skills. Data were collected using quantitative and qualitative tools including: pre and post questionnaires and nine (three students from each group depth interviews upon completion of the course. Findings, based on students` perceived evaluation, pinpointed on the advantages of the online course for students of the three groups. LD students’ achievements were not inferior to those of their peers, excellent students and average students. Yet, it carefully reports on a slight but explicitly marginal perceived evaluation of the LD students in comparison to excellent students and average students regarding: forum participation, authentic task and water lab performance. The article discusses the affordance of the online course via additional features that can be grouped into two categories: knowledge construction and flexibility in time, interaction and knowledge. Further research is suggested to extend the current study by examine the effect of other courses and different contents and by considering various evaluation methods of online courses, such as: observation, the think aloud, text and tasks analysis, and reflection.

In January 2005 R. Bock (GSI), P. Gibbon (FZ Juelich), J. Maruhn (Univ. Frankfurt), P. Mulser (TU Darmstadt), W. Scheid (Univ. Giessen), and T. Schlegel (GSI) established the ILIAS study group in high power laser interaction theory, with the following goals: To disseminate within ILIAS and collaborators the expertise in plasma, atomic, nuclear and nonlinear physics, and numerical simulation techniques held by individual members of the ILIAS study group. To coordinate the theoretical activities related to petawatt physics with lasers at GSI. To explore the potential of intense laser beams interacting with bulk matter, heavy ion beams and with mass-limited systems and single particles (e.g. cluster, mesoscopic and atomic physics). To propose relevant experiments for the PHELIX project and to discuss them in detail with the experimentalists in order to arrive at a coherent, GSI-specific scientific program. In elaborating such a concept the availability of the GSI accelerator system for laser petawatt experiments will play a major role. To attract and involve students and young researchers to establish a stable theoretical group of young experts. This goal could be reached within 2 - 3 years from now. To intensify these efforts a regular seminar is already held by the ILIAS members. By individual members pertinent lectures and seminars will be offered at their respective Universities. (orig.)

Full Text Available Customer satisfaction has long been recognized as a central concept of all business activities. Satisfaction can serve as an indicator of success of the company, both in the past and present, as well as an indicator of future performance. High quality service to students is a prerequisite of maintaining competitiveness in the market of higher education. A relationship that is created between the expectations of students and their satisfaction with the quality of service that provides educational institution plays an important role in shaping the reputation of academic institutions. Academic institutions are becoming aware of the importance of student satisfaction, because satisfaction positively influences their decision to continue their education at this institution, and the positive word of mouth that will attract prospective students. Satisfaction will affect student motivation, and therefore their performance. This paper provides insight into the marketing aspects of customer satisfaction, primarily insight into the satisfaction of students in the educational sector. The aim is to establish the influence of satisfaction various factors related to the university and higher education to the satisfaction of student life, and does student life satisfaction affect the overall happiness and student performance. The research was conducted on the student population of the University of Split, on a sample of 191 respondents. The research was conducted with the help of online survey questionnaire. The claim that student’s satisfactions with housing affect the satisfaction with the quality of student life is rejected. The results confirmed that the student’s satisfaction with university contents, university bodies and services, teaching, teaching methods and academic reputation affects the satisfaction of student life and student life satisfaction affect the student performance.

The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

Alginate capsules have several applications. Their functionality depends considerably on their permeability, chemical and mechanical stability. Consequently, the creation of composite system by addition of further components is expected to control mechanical and release properties of alginate capsules. Alginate and alginate-sodium caseinate composite liquid-core capsules were prepared by a simple extrusion. The influence of the preparation pH and sodium caseinate concentration on capsules physico-chemical properties was investigated. Results showed that sodium caseinate influenced significantly capsules properties. As regards to the membrane mechanical stability, composite capsules prepared at pH below the isoelectric point of sodium caseinate exhibited the highest surface Young's modulus, increasing with protein content, explained by potential electrostatic interactions between sodium caseinate amino-groups and alginate carboxylic group. The kinetic of cochineal red A release changed significantly for composite capsules and showed a pH-responsive release. Sodium caseinate-dye mixture studied by absorbance and fluorescence spectroscopy confirmed complex formation at pH 2 by electrostatic interactions between sodium caseinate tryptophan residues and cochineal red sulfonate-groups. Consequently, the release mechanism was explained by membrane adsorption process. This global approach is useful to control release mechanism from macro and micro-capsules by incorporating guest molecules which can interact with the entrapped molecule under specific conditions.

D'où vient l'univers ? Et d'où vient même qu'il y ait un univers ? Aura-t-il une fin ? Pourquoi les humains y sont-ils apparus ? Si ces questions nous obsèdent depuis toujours, celle de l'origine demeure la plus mystérieuse, la plus vertigineuse, d'où la profusion de discours — mythologiques, religieux ou philosophiques — qui tentent d'y répondre. C'est grâce à la science, aux découvertes de Newton, Galilée, Edwin Hubble, Alexandre Friedmann et Georges Lemaître, qu'on peut retracer le grand récit de l'univers, remonter son histoire à 13,7 milliards d'années, jusqu'à cette phase très dense et très chaude qu'on a appelée le big bang. Mais celui-ci n'est pas pour autant, comme on l'a imaginé, cette explosion originelle qui aurait créé tout ce qui existe. Cet instant zéro, peut-on le décrire, le penser, raconter d'où il peut bien provenir ? Et d'où serait venu l'univers d'avant le big bang ? Mystère !

Megan Kek

2017-07-01

Full Text Available This emerging initiative stemmed from an Office for Learning and Teaching Project (OLT project, Transforming Practice Programme 2016: Student Engagement: Students as Partners in Teaching and Learning. The initiative, trialed in semester two, 2016, involved the selection and training of two experienced students to be leaders of a Closed Facebook ‘students-only’ community which provided advice and triaged queries to appropriate channels. The evaluative processes comprised a participatory action research methodology. Two student leaders who facilitated the Closed Facebook and four academic staff of the project were the participants. The findings demonstrate that the Closed Facebook students-only site provided a safe space, outside the formal learning/classroom environment, where student participants were able to ask and share knowledge. The informal student-for-student learning community complemented the formal structure by facilitating the opportunity for students to become ‘experts’ as university students as they move-through their learning journey.

2010-02-15

Global health education is becoming more important for developing well-rounded physicians and may encourage students toward a career in primary care. Many medical schools, however, lack adequate and structured opportunities for students beginning the curriculum. Second-year medical students initiated, designed, and facilitated a pass-fail international health elective, providing a curricular framework for preclinical medical students wishing to gain exposure to the clinical and cultural practices of a developing country. All course participants (N=30) completed a post-travel questionnaire within one week of sharing their experiences. Screening reflection essays for common themes that fulfill university core competencies yielded specific global health learning outcomes, including analysis of health care determinants. Medical students successfully implemented a sustainable global health curriculum for preclinical student peers. Financial constraints, language, and organizational burdens limit student participation. In future, long-term studies should analyze career impact and benefits to the host country.

1989-07-01

The 12 month period from May 1988 to July 1989 represents the first full year of our 18 month pilot program in nuclear structure research. In this period, research was initiated to develop a capability for radioactive secondary beams at Argonne National Laboratory using the Atlas and the new Fragment Mass Analyzer (FMA), which is currently under construction. Two major new detector facilities are currently in the final stages of design and testing. The Large-Area, Scintillator Telescope (LAST) detector is fully operational and will be shipped to Argonne National Laboratory in August for fit-tests and in-beam calibrations. The first segments of a new sixteen-segment neutron multiplicity detector have been built and tested. The remaining segments are currently being constructed. Research was continued in the areas of (1) Coulomb excitation studies of rare earth and actinide nuclei; (2) In-beam, gamma-ray spectroscopy of nuclei in the mass 100 region, and (3) Advanced detector design. Several journal articles and abstracts were published or submitted for publication in the reporting period, and others are currently in preparation. Three graduate students participated in the program, one from the University of Florida and two from the Royal Institute of Technology, Stockholm, Sweden.

EXPLORING THE RELATIONS BETWEEN STUDENT CYNICISM AND STUDENT BURNOUT.

Science.gov (United States)

Wei, Xueyan; Wang, Rongrong; Macdonald, Elizabeth

2015-08-01

Research on the negative effects of student cynicism has been limited, especially regarding its relation to student burnout. This study examined the relations among student cynicism (policy cynicism, academic cynicism, social cynicism, and institutional cynicism) and student burnout, as evidenced by emotional exhaustion, depersonalization, and reduced personal accomplishment, in a sample of 276 Chinese undergraduates. Hierarchical multiple regressions showed that four aspects of student cynicism together explained substantial variance in student burnout. Policy cynicism was the strongest contributor to emotional exhaustion. Social cynicism was the primary contributor to depersonalization, and also to reduced personal accomplishment. Student cynicism overall had the strongest relationship with reduced sense of personal achievement. The findings outline the negative functional relations between student cynicism and student burnout.

The Perceptions of Elementary School Teachers Regarding Their Efforts to Help Students Utilize Student-to-Student Discourse in Science

Science.gov (United States)

Craddock, Jennifer Lovejoy

The purpose of this phenomenological study was to examine the perceptions of elementary teachers who teach science as opposed to science teacher specialists regarding their efforts to help students use student-to-student discourse for improving science learning. A growing body of research confirms the importance of a) student-to-student discourse for making meaning of science ideas and b) moving students' conceptual development towards a more scientific understanding of the natural world. Based on those foundations, the three research questions that guided this study examined the value elementary teachers place on student-to-student discourse, the various approaches teachers employ to promote the use of student-to-student discourse for learning science, and the factors and conditions that promote and inhibit the use of student-to-student discourse as an effective pedagogical strategy in elementary science. Data were gathered from 23 elementary teachers in a single district using an on-line survey and follow-up interviews with 8 teachers. All data were analyzed and evolving themes led to the following findings: (1) elementary teachers value student-to-student discourse in science, (2) teachers desire to increase time using student-to-student discourse, (3) teachers use a limited number of student-to-student discourse strategies to increase student learning in science, (4) teachers use student-to-student discourse as formative assessment to determine student learning in science, (5) professional development focusing on approaches to student-to-student discourse develops teachers' capacity for effective implementation, (6) teachers perceive school administrators' knowledge of and support for student-to-student discourse as beneficial, (7) time and scheduling constraints limit the use of student-to-student discourse in science. Implications of this study included the necessity of school districts to focus on student-to-student discourse in science, provide teacher and

Solar Heliospheric and INterplanetary Environment (SHINE) Students - Student Representatives' Perspectives

Science.gov (United States)

Pahud, D. M.; Niembro, T.

2014-12-01

The SHINE workshop is an annual meeting of solar and heliospheric scientists which, in addition to aiming to improve understanding of solar disturbances and their propagation to, and effect, on the Earth (shinecon.org), is dedicated to actively supporting students. This dedication is substantiated in part through the National Science Foundation (NSF) providing funding for student attendance to the workshop, which enables student participation. Another example of SHINE's commitment to its student members is the incorporation of a Student Day prior to the workshop since 2003, entirely organized and run by two student representatives. While there are variations in format from year to year, Student Day consists of tutorials and research talks exclusively by student volunteers to an audience of only students. The day is intended to provide a low-stress environment for students to learn about the various topics addressed during the workshop, to ask questions freely, and to engage in scientific discussion with other students which hopefully is a catalyst for collaboration. As a result of positive experiences, over the past decade student attendance and participation in the workshop have increased. At the SHINE 2014 workshop, nearly a third of attendees were students. SHINE student visibility has increased over the years, with student posters being advertised at breakfast, inclusion of a student day summary by the student representatives during a plenary session, and continued support from the steering committee. Students are also promoting a broader impact of SHINE sciences via increased social media presence. From a student representative's perspective, SHINE has built and fostered a healthy student community and encourages students to engage in shaping the future of the field.

2017-04-01

Operationalization processes are important for Weather and Climate Services. Complex data and work flows need to be combined fast to fulfill the needs of service centers. Standards in data and software formats help in automatic solutions. In this study we show a software solution in between hindcasts, forecasts, and validation to be operationalized. Freva (see below) structures data and evaluation procedures and can easily be monitored. Especially in the development process of operationalized services, Freva supports scientists and project partners. The showcase of the decadal climate prediction project MiKlip (fona-miklip.de) shows such a complex development process. Different predictions, scientists input, tasks, and time evolving adjustments need to be combined to host precise climate informations in a web environment without losing track of its evolution. The Freie Univ Evaluation System Framework (Freva - freva.met.fu-berlin.de) is a software infrastructure for standardized data and tool solutions in Earth system science. Freva runs on high performance computers to handle customizable evaluation systems of research projects, institutes or universities. It combines different software technologies into one common hybrid infrastructure, including all features present in the shell and web environment. The database interface satisfies the international standards provided by the Earth System Grid Federation (ESGF). Freva indexes different data projects into one common search environment by storing the meta data information of the self-describing model, reanalysis and observational data sets in a database. This implemented meta data system with its advanced but easy-to-handle search tool supports users, developers and their plugins to retrieve the required information. A generic application programming interface (API) allows scientific developers to connect their analysis tools with the evaluation system independently of the programming language used. Users of the

Full text: One objective of the Indian Ocean Experiment (INDOEX 1999) was to characterize the chemical composition of pollution outflow from South Asia. Real-time single particle analysis (ATOFMS, Univ. of California- Riverside), CO analysis (Nondispersive Infrared Gas Filter Correlation Photometer, Univ. of Maryland) and fast-response VOC measurements (PTR-MS, Univ. of Innsbruck) measurements were performed onboard the NOAA R/V Ronald H. Brown. Gas phase and aerosol chemical composition of encountered air parcels changed according to their geographic origin traced by backtrajectory analysis (continental air from Arabia and India; maritime air). The relative strength of combustion related pollution sources (biomass burning (BB) vs. fossil fuel (FF) combustion) was determined from the relative abundance of different tracers: acetonitrile (BB), CO (BB and FF), submicron particles containing carbon but no potassium (FF), submicron particles containing carbon and potassium (BB and coal combustion), submicron particles containing carbon, potassium and lithium (coal combustion). Arabian air clearly reflected the signature of fossil fuel combustion, while air from the Indian subcontinent was strongly influenced by biomass burning. (author)

In the last years research on the didactics of Psychiatry and opinions of medical students on Psychiatry has gained great interest. The authors think that this research could be useful for the improvement of didactics, for better understanding the meanings of professional choice, the identity of psychiatrist and their relationship with colleagues in other medical field. The goal of this research work was a preliminary survey of Genoese University Medical Student's opinions about psychiatry didactics, and choice of specialization. A questionnaire was submitted to all the students who passed Clinical Psychiatry examination in the period from November 1987 to December 1988. The students were divided in two randomized groups: the first group of students (224) was submitted to the questionnaire immediately after Clinical Psychiatry examination; while to the second group of students (66) the questionnaire was mailed. The aim of the questions was to assess the student's opinions on psychiatry, psychoanalysis, psychotherapy, the career they wanted to take up, and the difficulties of studying psychiatry: 69% of the students of the first group and 42% of the students of the second group answered the questionnaire. Female students answered that they preferred psychiatric specialization more than their male colleagues did, but the difference has no statistical importance. In most cases, the students who answered that they have taken into account psychiatry as a choice of specialisation, are more interested in medical specialties (primary care, etc.) than in surgical specialties. Most of the medical students declare some emotional troubles (anxiety, sleeplessness, problem in social relations).(ABSTRACT TRUNCATED AT 250 WORDS)

Early school withdrawal, commonly referred to as dropout, is associated with a plethora of negative outcomes for students, schools, and society. Student engagement, however, presents as a promising theoretical model and cornerstone of school completion interventions. The purpose of the present study was to validate the Student Engagement Instrument-Elementary Version (SEI-E). The psychometric properties of this measure were assessed based on the responses of an ethnically diverse sample of 1,943 students from an urban locale. Exploratory and confirmatory factor analyses indicated that the 4-factor model of student engagement provided the best fit for the current data, which is divergent from previous SEI studies suggesting 5- and 6-factor models. Discussion and implications of these findings are presented in the context of student engagement and dropout prevention. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

The Draconoid meteor shower, originating from comet 21P/Giacobini-Zinner, is a low-velocity Earth-crossing dust stream that had a peak anticipated flux on Oct. 8, 2012. In response to this prediction, NASA performed dedicated stratospheric dust collections to target interplanetary dust particles (IDPs) from this comet stream on Oct 15-17, 2012 [3]. Twelve dust particles from this targeted collection were allocated to our coordinated analysis team for studies of noble gas (Univ. Minnesota, Minnesota State Univ.), SXRF and Fe-XANES (SSL Berkeley) and mineralogy/isotopes (JSC). Here we report a mineralogical study of 3 IDPs from the Draconoid collection..

Fostering and maintaining students' interest in science is an important aspect of improving science learning. The focus of this paper is to listen to and reflect on students' voices regarding the sources of motivation for science subjects among students in community secondary schools with contextual challenges in Tanzania. We conducted a group-interview study of 46 Form 3 and Form 4 Tanzanian secondary school students. The study findings reveal that the major contextual challenges to student motivation for science in the studied schools are limited resources and students' insufficient competence in the language of instruction. Our results also reveal ways to enhance student motivation for science in schools with contextual challenges; these techniques include the use of questioning techniques and discourse, students' investigations and practical work using locally available materials, study tours, more integration of classroom science into students' daily lives and the use of real-life examples in science teaching. Also we noted that students' contemporary life, culture and familiar language can be utilised as a useful resource in facilitating meaningful learning in science in the school. Students suggested that, to make science interesting to a majority of students in a Tanzanian context, science education needs to be inclusive of students' experiences, culture and contemporary daily lives. Also, science teaching and learning in the classroom need to involve learners' voices.

As part of the International Mars Watch, Goldstone radar observations of Mars are planned during the 1999 Opposition ( Feb.'99-Aug'99). While some observing time is already allocated, a number of tracks could be made available for well-focused scientific objectives. Since the Deep Space Network plans far in advance, now is the time to develop your plans. During the next Mars opposition, the sub-Earth latitudes are in Mars' Northern hemisphere over the most northerly terrain accessible, which has not been previously examined with current sensitivity. The North residual ice cap is of particular interest. As a reminder to the Planetary Science community, observing proposals from any scientist with peer-reviewed planetary funding are solicited and should be forwarded to Martin.A.Slade@jpl.nasa.gov by email. Data reduction can, in principle, be carried out over the Internet. A graduate student or postdoctoral fellow resident at JPL for short period is recommended, however, to become familiar with suite of software for data analysis. Unfortunately, JPL cannot guarantee travel reimbursement due to funding limitations. We urge your consideration of becoming involved with the acquisition and analysis of Goldstone radar data. In the recent past, P.I.'s or co-I.s from Cornell, Arecibo/NAIC, Washington State University, Univ. Cal. Berkeley, Harvard -Smithsonian Center for Astrophysics, Univ. of Chicago, the DLR, Kashima SRC, ISAS, the Russian Academy of Science, the Russian Space Agency, and the USGS, have participated in radar experiments with Goldstone transmitting. This work is supported by the California Institute of Technology, under contract with NASA.

Purpose Effective clinical leadership is crucial to avoid failings in the delivery of safe health care, particularly during a period of increasing scrutiny and cost-constraints for the National Health Service (NHS). However, there is a paucity of leadership training for health-care students, the future leaders of the NHS, which is due in part to overfilled curricula. The purpose of this study was to assess the impact of student-led leadership training for the benefit of fellow students. Design/methodology/approach To address this training gap, a group of multiprofessional students organised a series of large-group seminars and small-group workshops given by notable health-care leaders at a London university over the course of two consecutive years. Findings The majority of students had not previously received any formal exposure to leadership training. Feedback post-events were almost universally positive, though students expressed a preference for experiential teaching of leadership. Working with university faculty, an inaugural essay prize was founded and student members were given the opportunity to complete internships in real-life quality improvement projects. Originality/value Student-led teaching interventions in leadership can help to fill an unmet teaching need and help to better equip the next generation of health-care workers for future roles as leaders within the NHS.

Students have a low mathematical ability because they are used to learning to hear the teacher's explanation. For that students are given activities to sharpen his ability in math. One way to do that is to create discovery learning based work sheet. The development of this worksheet took into account specific student learning styles including in schools that have classified students based on multiple intelligences. The dominant learning styles in the classroom were intrapersonal and interpersonal. The purpose of this study was to discover students’ responses to the mathematics work sheets of the junior high school with a discovery learning approach suitable for students with Intrapersonal and Interpersonal Intelligence. This tool was developed using a development model adapted from the Plomp model. The development process of this tools consists of 3 phases: front-end analysis/preliminary research, development/prototype phase and assessment phase. From the results of the research, it is found that students have good response to the resulting work sheet. The worksheet was understood well by students and its helps student in understanding the concept learned.

Full Text Available Objective: The objective of this study was to measure the effect of student-led educational events on geriatric patient and student participant perceptions in a community setting. Methods: Students led three events at a senior community center, focusing on learning and memory, sleep hygiene, and arthritis pain. The participants were geriatric patients who themselves were providers of support to homebound peers (“clients” through an independently organized program. Geriatric participants completed pre- and post-event surveys to measure changes in familiarity with the topics. Student participants also completed pre- and post-event surveys that tracked changes in their comfort in working with the geriatric population. Results: Each event demonstrated at least one positive finding for geriatric patients and/or their clients. Students reported increased comfort in working with and teaching the geriatric population following the first and third events, but not the second. Conclusion: Student-led educational sessions can improve perceived health-related knowledge of geriatric participants while simultaneously exposing students to the geriatric patient population. Overall, both students and geriatric participants benefited from these events. Practice Implications: Incorporation of single, student-led educational events could be mutually beneficial to students and the elderly population in the community and easily incorporated into any healthcare curriculum. Funding:This work was supported by a Butler University Innovation Fund Grant. Treatment of Human Subjects: IRB review/approval required and obtained   Type: Original Research

Multiphoton microscopy: an efficient tool for in-situ study of cultural heritage artifacts

Science.gov (United States)

Latour, Gaël.; Echard, Jean-Philippe; Didier, Marie; Schanne-Klein, Marie-Claire

2013-05-01

We present multimodal nonlinear optical imaging of historical artifacts by combining Two-Photon Excited Fluorescence (2PEF) and Second Harmonic Generation (SHG) microscopies. Three-dimensional (3D) non-contact laser-scanning imaging with micrometer resolution is performed without any preparation of the objects under study. 2PEF signals are emitted by a wide range of fluorophores such as pigments and binder, which can be discriminated thanks to their different emission spectral bands by using suitable spectral filters in the detection channel. SHG signals are specific for dense non-centrosymmetric organizations such as the crystalline cellulose within the wood cell walls. We also show that plaster particles exhibit SHG signals. These particles are bassanite crystals with a non-centrosymmetric crystalline structure, while the other types of calcium sulphates exhibit a centrosymmetric crystalline structure with no SHG signal. In our study, we first characterize model single-layered samples: wood, gelatin-based films containing plaster or cochineal lake and sandarac film containing cochineal lake. We then study multilayered coating systems on wood and show that multimodal nonlinear microscopy successfully reveals the 3D distribution of all components within the stratified sample. We also show that the fine structure of the wood can be assessed, even through a thick multilayered varnish coating. Finally, in situ multimodal nonlinear imaging is demonstrated in a historical violin. SHG/2PEF imaging thus appears as an efficient non-destructive and contactless 3D imaging technique for in situ investigation of historical coatings and more generally for wood characterization and coating analysis at micrometer scale.

Changes in the autotrophic pico- (0.2-2 microm), nano- (2-20 microm), and microplankton (>20 microm) biomass (chlorophyll a) and primary production were measured in the estuarine and coastal waters off Cochin, southwest coast of India during the onset and establishment of a monsoon. During this period, the estuary was dominated by nutrient-rich freshwater, whereas the coastal waters were characterized with higher salinity values (>30 psu) and less nutrients. The average surface chlorophyll a concentrations and primary production rates were higher in the estuary (average 13.7 mg m(-3) and 432 mgC m(-3) day(-1)) as compared to the coastal waters (5.3 mg m(-3) and 224 mgC m(-3) day(-1)). The nanoplankton community formed the major fraction of chlorophyll a and primary production, both in the estuary (average 85 +/- SD 8.3% and 81.2 +/- SD 3.2%) and the coastal waters (average 73.2 +/- SD 17.2% and 81.9 +/- 15.7%). Nanoplankton had the maximum photosynthetic efficiency in the coastal waters (average 4.8 +/- SD 3.9 mgC mgChl a m(-3) h(-1)), whereas in the estuary, the microplankton had higher photosynthetic efficiency (average 7.4 +/- 7 mgC mgChl a m(-3) h(-1)). The heavy cloud cover and increased water column turbidity not only limit the growth of large-sized phytoplankton in the Cochin estuary and coastal waters but also support the proliferation of nanoplankton community during the monsoon season, even though large variation in nanoplankton chlorophyll a and production exists between these two areas.

Student Perceptions of Their Biology Teacher's Interpersonal Teaching Behaviors and Student Achievement

Madike, Victor N.

Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions was administered to 318 undergraduate biology students. Non-parametric Spearman's rank correlations revealed a significant direct correlation between students' grades and their perceptions of teachers' interpersonal teaching behaviors. The relationship between student achievement and students' perceptions of student-teacher interactions prompted the recommendation for additional study on the importance of student-teacher interactions in undergraduate programs. A recommendation for local practice included faculty development on strategies for improving student-teacher interactions. The study's implications for positive social change include increased understanding for administrators and instructors on the importance of teacher-student interactions at the community college level.

2017-12-01

The purpose of this study is to reveal the development of knowledge of ordinary students to be like gifted students in the classroom based on Piaget's theory. In exposing it, students are given an open problem of classical analogy. Researchers explore students who conjecture via analogical reasoning in problem solving. Of the 32 students, through the method of think out loud and the interview was completed: 25 students conjecture via analogical reasoning. Of the 25 students, all of them have almost the same character in problem solving/knowledge construction. For that, a student is taken to analyze the thinking process while solving the problem/construction of knowledge based on Piaget's theory. Based on Piaget's theory in the development of the same knowledge, gifted students and ordinary students have similar structures in final equilibrium. They begin processing: assimilation and accommodation of problem, strategies, and relationships.

Understanding obsessive-compulsive behavior in medical students and law students is necessary for administrators and educators to properly work with students struggling with obsessionality. We aim to compare the differences in obsessive symptoms between medical students, law students and a control population. A total of 100 third-year medical students, 102 third-year law students and 103 control subjects drawn from the general population completed the Leyton Obsessional Inventory (LOI). Subjects were examined on all three sections (symptoms/traits, resistance and interference) of the LOI. Obsessional symptom scores for medical students (14.29 ± 7.33) and law students (13.65 ± 6.61) were significantly greater than for the control group (11.58 ± 7.45). Medical and law students were both more likely to report checking, order, routine and attention to detail as obsessive symptoms. Medical students were more likely than law students to possess the obsessive symptoms of cleanliness and conscientiousness, while law students were more likely than medical students to possess obsessive symptoms related to difficulty in making up their mind and doubting themselves. While medical students and law students are more obsessional than the control population, each group is more likely to report different obsessive symptoms.

Objective. To determine the impact of student or faculty facilitation on student self-assessed attitudes, confidence, and competence in motivational interviewing (MI) skills; actual competence; and evaluation of facilitator performance. Methods. Second-year pharmacy (P2) students were randomly assigned to a student or faculty facilitator for a four-hour, small-group practice of MI skills. MI skills were assessed in a simulated patient encounter with the mMITI (modified Motivational Interviewing Treatment Integrity) tool. Students completed a pre-post, 6-point, Likert-type assessment addressing the research objectives. Differences were assessed using a Mann-Whitney U test. Results. Student (N=44) post-test attitudes, confidence, perceived or actual competence, and evaluations of facilitator performance were not different for faculty- and student-facilitated groups. Conclusion. Using pharmacy students as small-group facilitators did not affect student performance and were viewed as equally favorable. Using pharmacy students as facilitators can lessen faculty workload and provide an outlet for students to develop communication and facilitation skills that will be needed in future practice.

Student assistantships: bridging the gap between student and doctor

Full Text Available James GM Crossley,1,2 Pirashanthie Vivekananda-Schmidt1 1University of Sheffield School of Medicine, Sheffield, 2Chesterfield Royal Hospital NHS Foundation Trust, Chesterfield, UK Abstract: In 2009, the General Medical Council UK (GMC published its updated guidance on medical education for the UK medical schools – Tomorrow's Doctors 2009. The Council recommended that the UK medical schools introduce, for the first time, a clinical placement in which a senior medical student, “assisting a junior doctor and under supervision, undertakes most of the duties of an F1 doctor”. In the UK, an F1 doctor is a postgraduation year 1 (PGY1 doctor. This new kind of placement was called a student assistantship. The recommendation was considered necessary because conventional UK clinical placements rarely provided medical students with opportunities to take responsibility for patients – even under supervision. This is in spite of good evidence that higher levels of learning, and the acquisition of essential clinical and nontechnical skills, depend on students participating in health care delivery and gradually assuming responsibility under supervision. This review discusses the gap between student and doctor, and the impact of the student assistantship policy. Early evaluation indicates substantial variation in the clarity of purpose, setting, length, and scope of existing assistantships. In particular, few models are explicit on the most critical issue: exactly how the student participates in care and how supervision is deployed to optimize learning and patient safety. Surveys indicate that these issues are central to students' perceptions of the assistantship. They know when they have experienced real responsibility and when they have not. This lack of clarity and variation has limited the impact of student assistantships. We also consider other important approaches to bridging the gap between student and doctor. These include supporting the

The refusal of treatment is frequent in human immunodeficiency virus-positive adolescents. The clinical history of a teenage girl presenting severe immunodepression secondary to the virus, a depressive disorder and a refusal of treatment, illustrates the benefit of combined paediatric, child psychiatric and cross-cultural care as proposed by the Cochin-Paris Adolescent Centre. Working on the meaning of the refusal was a prerequisite for the construction of a care project forming part of a life project, as the psychopathological work could only begin once somatic care ensuring the patient's protection was in place.

The Multiverse education group at UC Berkeley's Space Sciences Lab created the NASA-funded "Five Stars Pathway" model in which five "generations" of girls and women engage in science together in an afterschool setting, with each generation representing one stage in the pathway of pursuing a career in science, technology, engineering, or math (STEM). The five stages are: elementary-age students, middle-school-age students, undergraduate-level college students, graduate-level college students and professional scientists. This model was field-tested at two Girls Inc. afterschool locations in the San Francisco Bay Area and distributed to Girls Inc. affiliates and other afterschool program coordinators nationwide. This presentation will explore some of the challenges and success of implementing a multigenerational STEM model as well as distributing the free curriculum for interested scientists and college students to use with afterschool programs.

From students to researchers: The education of physics graduate students

Science.gov (United States)

Lin, Yuhfen

This dissertation aims to make two research contributions: (1) In physics education research, this work aims to advance our understanding of physics student learning at the graduate level. This work attempts to better understand how physics researchers and teachers are produced, and what factors support or encourage the process of becoming a researcher and a teacher. (2) In cognitive science research in the domain of expert/novice differences, researchers are interested in defining and understanding what expertise is. This work aims to provide some insight into some of the components of expertise that go into becoming a competent expert researcher in the domain of physics. This in turn may contribute to our general understanding of expertise across multiple domains. Physics graduate students learn in their classes as students, teach as teaching assistants, and do research with research group as apprentices. They are expected to transition from students to independent researchers and teachers. The three activities of learning, teaching, and research appear to be very different and demand very different skill-sets. In reality, these activities are interrelated and have subtle effects on each other. Understanding how students transition from students to researchers and teachers is important both to PER and physics in general. In physics, an understanding of how physics students become researchers may help us to keep on training physicists who will further advance our understanding of physics. In PER, an understanding of how graduate students learn to teach will help us to train better physics teachers for the future. In this dissertation, I examine physics graduate students' approaches to teaching, learning, and research through semi-structured interviews. The collected data is interpreted and analyzed through a framework that focuses on students' epistemological beliefs and locus of authority. The data show how students' beliefs about knowledge interact with their

2018-02-01

Student attitudes, defined as the extent to which one holds expertlike beliefs about and approaches to physics, are a major research topic in physics education research. An implicit but rarely tested assumption underlying much of this research is that student attitudes play a significant part in student learning and performance. The current study directly tested this attitude-learning link by measuring the association between incoming attitudes (Colorado Learning Attitudes about Science Survey) and student learning during the semester after statistically controlling for the effects of prior knowledge [early-semester Force Concept Inventory (FCI) or Brief Electricity and Magnetism Assessment (BEMA)]. This study spanned four different courses and included two complementary measures of student knowledge: late-semester concept inventory scores (FCI or BEMA) and exam averages. In three of the four courses, after controlling for prior knowledge, attitudes significantly predicted both late-semester concept inventory scores and exam averages, but in all cases these attitudes explained only a small amount of variance in concept-inventory and exam scores. Results indicate that after accounting for students' incoming knowledge, attitudes may uniquely but modestly relate to how much students learn and how well they perform in the course.

Standardised patients are used in medical education to expose students to clinical contexts and facilitate transition to clinical practice, and this approach is gaining momentum in physiotherapy programs. Expense and availability of trained standardised patients are factors limiting widespread adoption, and accessing clinical visits with real patients can be challenging. This study addressed these issues by engaging senior students as standardised patients for junior students. It evaluated how this approach impacted self-reported constructs of both the junior and senior students. Learning activities for undergraduate physiotherapy students were developed in five courses (Neurology, Cardiorespiratory and three Musculoskeletal courses) so that junior students (Year 2 and 3) could develop skills and confidence in patient interview, physical examination and patient management through their interaction with standardised patients played by senior students (Year 4). Surveys were administered before and after the interactions to record junior students' self-reported confidence, communication, preparedness for clinic, and insight into their abilities; and senior students' confidence and insight into what it is like to be a patient. Satisfaction regarding this learning approach was surveyed in both the junior and senior students. A total of 253 students completed the surveys (mean 92.5% response rate). Across all courses, junior students reported a significant (all P Senior students demonstrated a significant improvement in their confidence in providing feedback and insight into their own learning (P senior students as standardised patients resulted in positive experiences for both junior and senior students across a variety of physiotherapy areas, activities, and stages within a physiotherapy program.

"Nursing Students Assaulted": Considering Student Safety in Community-Focused Experiences.

Science.gov (United States)

Maneval, Rhonda E; Kurz, Jane

2016-01-01

Community nursing experiences for undergraduate students have progressed beyond community-based home visits to a wide array of community-focused experiences in neighborhood-based centers, clinics, shelters, and schools. Our Bachelor of Science in Nursing program chose to use sites situated within neighborhoods close to campus in order to promote student and faculty engagement in the local community. These neighborhood sites provide opportunities for students to deliver nursing services to underserved and vulnerable populations experiencing poverty and health disparities. Some of these neighborhoods are designated as high crime areas that may potentially increase the risk of harm to students and faculty. There is a need to acknowledge the risk to personal safety and to proactively create policies and guidelines to reduce potential harm to students engaged in community-focused experiences. When a group of baccalaureate nursing students was assaulted while walking to a neighborhood clinic, the faculty was challenged as how to respond given the lack of policies and guidelines. Through our experience, we share strategies to promote personal safety for students and recommend transparency by administrators regarding potential safety risks to students engaged in community-focused fieldwork activities.

Introduction Many studies have shown financial worries and debt to induce stress in individuals, this combined with the existing stress of being a dentist raises the question of how student debt affects students' and dentists' stress levels.Objectives Determine whether student debt has had any noticeable effect on student stress levels; investigate whether student debt has any effect on dentists' career choice; investigate whether the increase in tuition fees has influenced the number of applicants to study dentistry at the University of Birmingham.Method Anonymous questionnaires were completed by 70 4th year and 38 5th year BDS and 22 Dental Core Trainees (DCTs). Participants circled the response which best fitted their situation regarding statements on their level of stress and future career path. Ethical approval granted. Application figures to study dentistry obtained from head of admissions.Results Forty-two percent of males and 63% of females strongly agreed with the statement that having no debt would reduce their stress levels. Of those with debt >£40,000, 11% strongly agreed and 42% agreed that their total amount of student debt causes them stress. Whereas, those whose debt is stress. Seventy-seven percent of participants who had parental or family financial support reported this reduced their stress levels. Student debt was found to deter females from undertaking further study more than it deters males (P stressed about their total student loan(s) (P stress (P stress; students reporting a higher level of debt also report more stress and concern about paying off their student debt. Having no student debt would reduce stress levels, although to what extent is undetermined. Applications to study dentistry have fallen since the increase in tuition fees.

Froneman, Kathleen; Du Plessis, Emmerentia; Koen, Magdelene P

2016-06-10

Little research has been conducted in private nursing schools with regard to the educator-student relationship to strengthen the resilience of nursing students and to improve the educator-student relationship. An effective educator-student relationship is a key factor to ensure a positive learning climate where learning can take place and resilience can be strengthened. The purpose was to explore and describe nursing students' view on the basic elements required for an effective educator-student relationship to strengthen their resilience and the educator-student relationship. This study followed an explorative, descriptive and contextual qualitative design in a private nursing education institution in the North West Province. Purposive sampling was used. The sample consisted of 40 enrolled nursing auxiliary students. The World Café Method was used to collect data, which were analysed by means of content analysis. The following five main themes were identified and included: (1) teaching-learning environment, (2) educator-student interaction, (3) educator qualities, (4) staying resilient and (5) strategies to strengthen resilience. Students need a caring and supportive environment; interaction that is constructive, acknowledges human rights and makes use of appropriate non-verbal communication. The educator must display qualities such as love and care, respect, responsibility, morality, patience, being open to new ideas, motivation, willingness to 'go the extra mile' and punctuality. Students reported on various ways how they manage to stay resilient. It thus seems that basic elements required in an effective educator-student relationship to strengthen the resilience of students include the environment, interaction, educator and student's qualities and resilience.

Despite increasing mental health needs among medical students, few models for effective preventive student wellness programs exist. This paper describes a novel approach developed at the University of California (UC) Davis School of Medicine: the Office of Student Wellness (OSW). Improved access and mental health service utilization have been documented, with over half of all students receiving support and clinical care. UC Davis student satisfaction mean scores on the Association of American Medical Colleges Graduation Questionnaire wellness questions have reached or exceeded national average over the last 4 years, since the OSW was founded. This program may serve as a blueprint for other medical schools in developing effective student wellness programs.

EC-Marie Curie Initial Training Networks (ITN) projects aim to improve the career perspectives of young generations of researchers. Institutions from both academic and industry sectors form a collaborative network to recruit research fellows and provide them with opportunities to undertake research in the context of a joint research training program. In this frame, TOPOMOD - one of the training activities of EPOS, the new-born European Research Infrastructure for Geosciences - is a funded ITN project designed to investigate and model how surface processes interact with crustal tectonics and mantle convection to originate and develop topography of the continents over a wide range of spatial and temporal scales. The multi-disciplinary approach combines geophysics, geochemistry, tectonics and structural geology with advanced geodynamic numerical/analog modelling. TOPOMOD involves 8 European research teams internationally recognized for their excellence in complementary fields of Earth Sciences (Roma TRE, Utrecht, GFZ, ETH, Cambridge, Durham, Rennes, Barcelona), to which are associated 5 research institutions (CNR-Italy, Univ. Parma, Univ. Lausanne, Univ. Montpellier, Univ. Mainz) , 3 high-technology enterprises (Malvern Instruments, TNO, G.O. Logical Consulting) and 1 large multinational oil and gas company (ENI). This unique network places emphasis in experience-based training increasing the impact and international visibility of European research in modeling. Long-term collaboration and synergy are established among the overmentioned research teams through 15 cross-disciplinary research projects that combine case studies in well-chosen target areas from the Mediterranean, the Middle and Far East, west Africa, and South America, with new developments in structural geology, geomorphology, seismology, geochemistry, InSAR, laboratory and numerical modelling of geological processes from the deep mantle to the surface. These multidisciplinary projects altogether aim to

Present study was carried out to determine the inhibiting factors influencing the student's research projects from the view point of Yasuj University of Medical Sciences students in 2008. Materials & Methods: In this cross sectional study 96 students of Yasuj Medical University were selected by stratified random sampling. The data were collected by validate & reliable questionnaire, containing demographic information, inhibiting factors related to students (personal and organization. The data were analyzed by SPSS software. Results: The mean scores against the personal barriers and the organizational barriers questions were 43.23±12.96 and 62.58±12.08 respectively. There was a significant difference between personal and organizational barriers (P<0.001 and personal barriers were more important. According to the results, the student's inadequate skills & knowledge of research methodology and lack of awareness of research topics were the most prevalent personal barriers. The most prevalent organizational barriers were unavailability of research consulters, inadequate research skills of consulter, insufficient facilities & equipment and lack of motivating staff & faculties. Other variables such as gender, subject of study and research experience are mentioned in the full text. Conclusion: This study showed that the personal barriers were more important than organizational barriers which interfere with the student's research projects. This can be corrected and controlled by teachers, faculty members, university officials and students, themselves.

The main objective of the study was to see whether medical students use more desirable approaches to studying than general education students. Survey method was used to collect data from both the medical students and the general education students. The survey of the medical students was carried out between January and March, 2012. The survey was administered to all the medical students present in lecture halls on day of data collection, while general education students were randomly selected from four subject areas at two universities. In total, 976 medical students and 912 general students participated in the study. Of the general students, 494(54%) were boys and 418(46%)were girls with an overall mean age of 20.53±1.77 years (range: 17-27 years). The medical students' perceptions of their learning environment and their learning preferences were broadly similar to that of general education students with the exception of workload. The medical students perceived the workload to be less appropriate (Mean = 2.06±0.72) than the students in general education (Mean = 2.84±0.90). The medical students were more likely to use the deep approach to studying (Mean = 3.66±0.59) than the students in general education (Mean = 3.16±0.91). The students in general education were slightly more likely to use the organized studying (Mean = 3.44±0.90) than the medical students (Mean =3.23±0.90). Both medical students and the students in general education tended to use the surface approaches along with other approaches to studying. There was not a great difference between the medical students and the students pursuing general education with regard to perceptions of the learning environment and approaches to learning.

Do dental hygiene students fit the learning profile of the millennial student?

Science.gov (United States)

Blue, Christine M

2009-12-01

Differences in learning and the cultural context of our students' life experiences are important variables that faculty members need to understand in order to be effective in the classroom. Faculty members are finding that millennial students' approaches to learning are often vastly different from their own and as a result feel frustrated in their ability to help these students with their learning needs. Cultivating awareness of how today's dental hygiene student learns as well as the millennial learner profile can help faculty members address this educational challenge. The purpose of this study was to identify the learning styles of three groups of dental hygiene students and determine if they fit the learning profile of the millennial student as measured by the Learning Type Measure. Given this new generation of learners, it was hypothesized that dental hygiene students' learning style preferences would fit the learning profile of the millennial student. The Learning Type Measure was administered to 101 dental hygiene students at the University of Minnesota, University of Arizona, and Virginia Commonwealth University. The results from the study revealed that dental hygiene students do exhibit learning style preferences consistent with the millennial learner profile.

Gran, Sarah Frandsen; Braend, Anja Maria; Lindbaek, Morten

2010-01-01

Many medical students in general practice clerkships experience lack of observation-based feedback. The StudentPEP project combined written feedback from patients, observing teachers and students. This study analyzes the perceived usefulness of triangulated written feedback. A total of 71 general practitioners and 79 medical students at the University of Oslo completed project evaluation forms after a 6-week clerkship. A principal component analysis was performed to find structures within the questionnaire. Regression analysis was performed regarding students' answers to whether StudentPEP was worthwhile. Free-text answers were analyzed qualitatively. Student and teacher responses were mixed within six subscales, with highest agreement on 'Teachers oral and written feedback' and 'Attitude to patient evaluation'. Fifty-four per cent of the students agreed that the triangulation gave concrete feedback on their weaknesses, and 59% valued the teachers' feedback provided. Two statements regarding the teacher's attitudes towards StudentPEP were significantly associated with the student's perception of worthwhileness. Qualitative analysis showed that patient evaluations were encouraging or distrusted. Some students thought that StudentPEP ensured observation and feedback. The patient evaluations increased the students' awareness of the patient perspective. A majority of the students considered the triangulated written feedback beneficial, although time-consuming. The teacher's attitudes strongly influenced how the students perceived the usefulness of StudentPEP.

Borderless STEM education: A study of both American students and foreign students

Komura, Kiriko

This study explores the current status of borderless education in STEM through surveys of two populations of STEM students: American students who studied abroad and foreign students who were studying in the U.S. It was undertaken in response to the U.S. government's desires to strengthen STEM education and to develop American students' global competencies. The purpose was to understand how international experiences can be enhanced in order to increase American STEM students' interest in study abroad programs and in earning advanced STEM degrees and to understand how to attract more foreign STEM students to study in the United States. Issues of particular focus were: the impacts of gender, race/ethnicity, and nationality on STEM students' motivation to participate in, and responses to study abroad programs, and the value of Information and Communication Technologies (ICTs) in borderless STEM education. Several different forms of multivariate analyses were performed on data from surveys at seven public and private colleges and universities in the Southern California area. The results indicated that among American students, greater value was placed on social and cultural experiences gained through studying abroad. In contrast, among foreign students greater value was placed on enhancement of their academic and professional development opportunities. American students whose study abroad included research experiences had a greater interest in international research and teaching in the future. Foreign graduate students majoring in computer science, engineering and biology are the most likely to seek opportunities to study and work in the US. Finally, ICTs were valued by American students as platforms for social interactions and by foreign students for facilitating professional networks. The analyses lead to several recommendations, including: STEM faculty should be made aware of the critical importance of their advising and mentoring in motivating students to choose to

Full Text Available Due to the environmental conditions of the semiarid territory, livestock has constituted one of the main economic activities and plays an important role in regional economic system.The municipality of Caturité - PB is characterized by the predominance of cattle livestock as the main productive activity. In recent years, however, this is being threatened due to infestation of the Cochineal Carmine (Dactylopius opuntiae in plantations of spineless cactus (Opuntia ficus indica Mill, primary forage food for bovine and goat herds.As consequences of the devastation of spineless cactus, there has been the productive processes of dispossession and dislocation, with consequent loss of identity. In this sense, the objective of this work was to analyze public policies that have been established in the municipality of Caturité the major organs Municipal, State and Federal, seeking to reverse the current situation and promote rural development, as well as producers realize and given the actions of these bodies.Was used as the research methodology of theoretical frameworks, focusing on the concepts of rural areas, public policy and development, there was also the questionnaires in government agencies as well as to farmers in two rural communities surveyed (Serraria and Malhada daPanela aiming establish their socioeconomic profile.The results revealed the importance of agriculture for local development, as well as the environmental degradation caused by Cochineal carmine.There was also the implementation of new cactus cultivars resistant to pests as a possible referral to the minimization problem, which should have an answer in the medium term. However, it was found that the actions have been ad hoc and are not integrated into a broader development project that will be sustainable.

Oaxaca: Industrias familiares, comercio e inversiones a fines del siglo XIX

Full Text Available This article provides data and analysis of commercial/business relations between foreigners, the social élite and local politician in the Oaxaca in late in the 19th century, with the aim of establishing textile factories, mining and banks. This phenomenon of familiar interrelations was common in the porfirian Mexico, so it is also reference in parallel to other entities where that situation favoured three social actors –foreigners, the élite and the politician-from an enrichment of political-industrial families, which gave them the opportunity to extract their monetary resources outside Oaxaca's State. The central difference of Oaxaca with the rest of the States is that industrialization, mainly in the textile area, occurred very late, as the 19th century Oaxaca was continuing with the model of agricultural production-exportation, with the cochineal, which provoked the late entry of machinery and mechanical polluting infrastructure in the industrial sector, as well as the absence of road infrastructure favouring mining sector. Finally, the absence of strong investment and accumulated capital mass reflected in banks by entrepreneurs, whofrom families ties, preferred to invest the minimum necessary in the State of Oaxaca and most accommodating investments in other States, such Puebla, Veracruz and Mexico City. We infer that this way of pristine investment in resources was linked to two facts: The large investment in cochineal and the concept of worker, mostly indigenous. As in all cases of industrialization andin this particular oaxaquenian case, the majority of the population of Oaxaca's State and its natural resources were not favored directlybecause most important gains were invested and spendedout of Oaxaca.

The aim was to examine main reasons for students' medical school choice and their relationship with students' characteristics and motivation during the students' medical study. In this multisite cross-sectional study, all Year-1 and Year-4 students who had participated in a selection procedure in one of the three Dutch medical schools included in the study were invited to complete an online survey comprising personal data, their main reason for medical school choice and standard, validated questionnaires to measure their strength of motivation (Strength of Motivation for Medical School-Revised) and autonomous and controlled type of motivation (Academic Self-regulation Questionnaire). Four hundred seventy-eight students participated. We performed frequency analyses on the reasons for medical school choice and regression analyses and ANCOVAs to study their associations with students' characteristics and motivation during their medical study. Students indicated 'city' (Year-1: 24.7%, n=75 and Year-4: 36.0%, n=52) and 'selection procedure' (Year-1: 56.9%, n=173 and Year-4: 46.9%, n=68) as the main reasons for their medical school choice. The main reasons were associated with gender, age, being a first-generation university student, ethnic background and medical school, and no significant associations were found between the main reasons and the strength and type of motivation during the students' medical study. Most students had based their medical school choice on the selection procedure. If medical schools desire to achieve a good student-curriculum fit and attract a diverse student population aligning the selection procedure with the curriculum and taking into account various students' different approaches is important.

Et si notre Univers n'était qu un parmi d'autres ? Cette idée d'univers multiples, qui est envisagée depuis l'Antiquité, n'est entrée que récemment - et avec fracas - dans le champ de la science. Si l'hypothèse fascine, elle n'en est pas moins dérangeante : comment se formeraient ces mondes invisibles ? Auraient-ils les mêmes lois physiques ? Peut-on tester et réfuter leur existence ? Une telle hypothèse est-elle vraiment scientifique ? Faut-il en rester aux critères de scientificité traditionnels ou ouvrir la porte aux mondes possibles de l'astrophysique, de la philosophie et de l'imaginaire ? Un cosmologiste, un physicien théoricien, un philosophe et un historien de la science-fiction nous invitent à nous immerger au coeur de la physique théorique, à révolutionner la manière de concevoir ce qu'est une théorie physique signifiante, à extrapoler les lois de la nature pour décrire d'autres univers.

2013-09-01

Teaching is an important skill. Academic physicians teach on a daily basis, and nearly all physicians occasionally teach colleagues and patients. There are generally few opportunities for medical students to learn teaching skills. We developed a novel "near-peer" teaching program in which fourth-year students cotaught first-year students. Eighteen fourth-year students enrolled in our institution's primary senior radiology elective learned the basics of ultrasound through a series of lectures and hands-on scanning sessions. Each fourth-year student, paired with a radiology resident or attending, then cotaught a first-year anatomy small group session. After instruction, voluntary surveys were administered to assess the perceived value of the "near-peer" teaching experience. Seventeen of 18 (94%) and 104 of 120 (87%) administered surveys were returned by fourth- and first-year students, respectively. Sixteen (94%) and 99 (95%) of the fourth- and first-year students reported they "enjoyed" or "really enjoyed" the near-peer teaching experience. Fourteen (82%) of the fourth years perceived improvement in their teaching skills and an increase in their knowledge. Only 8 (47%) of the fourth years thought they were "helpful" or "very helpful," though 92 (88%) of the first years identified their fourth-year co-instructors as "helpful" or "very helpful." We piloted a novel "near-peer" program. Both senior and freshman students enjoyed the experience, and fourth years thought the session was educational for them as well. Although most fourth years did not judge themselves as helpful, first-year students overwhelmingly considered them a useful addition to the session. Copyright © 2013 AUR. Published by Elsevier Inc.

2014-07-01

To compare psychomotor function between a music student group who had music education and a non-music student group who participated in music training. Consecutive sampling was used for completing questionnaires, testing reaction times (visual, auditory, and tactile system), measuring electromyography of upper trapezius muscles both sides and taking photos of the Craniovertebral (CV) angle in the sitting position. Data collection was made twice for each student group: the music students at one-hour intervals for resting and conducting nonmusic activities, the non-music students at two-day intervals, 20 minutes/session, and performed music training (by a manual of keyboard notation). The non-music students (n = 65) improved reaction times, but responded slower than the music students except for the tactile system. The music students (n = 28) showed faster reaction times and higher activities of the trapezius muscle than the non-music students at post-test. In addition, the CV angle of the non-music students was significantly improved. The level of musical ability may influence the psychomotor function. Significant improvement was observed in visual, auditory and tactile reaction time, and CV angle in the non-music students. However upper trapezius muscle activities between both student groups were unchanged.

The study was conducted in seven private coeducational English-medium schools in Cochin to understand adolescent attitudes in this part of the country. Queries submitted by students (n=10,660) and responses to separate pretested questionnaires for boys (n=886 received) and girls (n=589 received) were analysed. The study showed a lacuna of knowledge among adolescents with the most frequently asked queries being on masturbation, and sex and sexuality. More than 50% of adolescents received information on sex and sexuality from peers; boys had started masturbating by 12 yr age and 93% were doing so by 15 yr age. Although 73% of girls were told about menstruation by their parents, 32% were not aware, at menarche, that such an event would occur and only 8% were aware of all aspects of maintaining menstrual hygiene. 19% of boys succumbed to peer pressure into reading/viewing pornography; more than 50% of adolescents admitted to having had an infatuation around 13 yrs of age or after. 13% of boys admitted to having been initiated into smoking by friends; mostly between 14-16 yrs age; 6.5% boys had consumed alcohol with peers or at family functions, starting between ages of 15 to 17 yrs. Though >70% of adolescents were aware about AIDS, adequate knowledge about its spread and prevention was lacking.

Culver, Jennifer

The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

Bostic, J.; Stylinski, C.; Doty, C.

2017-12-01

Teachers and their K-12 students lack firsthand experience in science research and often harbor misconceptions about science practices and the nature of science. To address this challenge, the NOAA-funded Student-Teacher-Researcher (STAR) partnership that provides rural high school students with authentic research experiences investigating the amount and sources of nitrate in schoolyard runoff. Teachers received training, guiding curricular materials aligned with NGSS and in-classroom support. With a focus on evidence-based reasoning skills, students actively participate in the research process through sample collection, data analysis, and an in-person discussion of conclusions and implications with our scientist team. As a member of this team, I assisted with refining the study design, analyzing nitrate isotope runoff samples, and sharing insights and feedback with students during the in-person discussion session. Assessment results indicate student gained an understanding of nitrate pollution and of science practices. As a graduate student, young scientist, and possessor of a B.S. in Science Education, I already recognized the value of involving K-12 students and teachers in authentic research experiences, as these experiences expose students to the nature of science while also improving content knowledge. During the STAR partnership, I learned firsthand some of the obstacles presented during outreach involving partnerships between a research institution and schools, such as inflexibility of school scheduling and the need for flexibility with research questions requiring complex lab analysis. Additionally, I discovered the challenge of working systemically across a school district, which can have broad impact but limit student experiences. Highlights of my experience included interactions with students and teachers, especially when students have unexpected answers to my questions, providing novel explanations for patterns observed in the data. Despite the

We administered a self-reporting questionnaire survey regarding the mental health conditions of high school students and attitudes of students and their teachers toward students' mental health issues. In addition, we discussed the requirements for high school students' mental health support system. The subjects were 3,312 students and 208 teachers in four Shizuoka prefectural public high schools in 2009. University Personality Inventory (UPI) is usually conducted to assess university students' mental state and is a questionnaire that high school students can answer easily. Therefore, we adopted UPI for this survey. UPI was composed of 56 unhealthy and 4 healthy condition items. High school students completed the UPI and determined the sum of unhealthy condition items; a higher score indicated a poorer mental health status. The average UPI score of all students (n = 3,312) was 12.7 points, and that of females (n = 1,217)was 15.2 points, which was significantly higher than the 11.3 points of males (n = 2,095). Those with scores > or = 30 points (7.5%), which was more than half of the maximum score, were designated as the High Score (HS) group and considered to have poor mental health. Those with scores of > or = 40 (1.4%) seemed to have very poor mental health, and there was concern that they may be suffering from psychosis. Our observations indicated that HS students were likely to avoid seeking help regarding mental health issues, which was especially true for male HS students. The majority of students chose their friends and parents as advisers, but HS students were significantly more likely to choose advisers who were engaged in jobs related to medical work. Students in both the HS and non-HS groups who did not wish to consult anyone else about their mental conditions wanted to be approached by those around them. High school teachers hesitated to intervene with mentally disturbed students and attempted to resolve problems within the school. Thus, it appears

Full Text Available Introduction & Objective: The prevalence of substance abuse among college students is increasing drastically and requires immediate skill-based substance abuse intervention such as assertive skills. The purpose of this study was to develope the healthy behavior to change the subjective norms of students in order to decrease their tendency towards substance abuse. Materials & Methods: A pre and post nonequivalent control group design study carried out on college students. A total number of 140 students were selected through randomized cluster sampling and randomly assigned to the intervention (n=70 and the control (n=70 groups. The data-gathering tool consisted of a self-report questionnaire assessing the variables of moral , descriptive , and injunctive norms. After the diagnostic evaluation, assertive skills promoting program was applied to persuade the participants against substances abuse. Respondents in the control and experimental groups completed questionnaires at baseline and 2 months after the intervention. Results: The result showed that educational manipulation had significant effect on intervention group’s average response for moral norms (t= -3.36, P<0.001, descriptive norms (t= -3.07, P<0.003, and injunctive norms for persuading substance abuse (t=-3.79, P<0.000.Conclusion: These findings suggest that assertive skills training would be an efficient tool in drug abuse prevention programs among adolescents that should also be included in the comprehensive school health programs.

Abstract Purpose To determine the self-concepts of chiropractic students as science students and if any personal variable affect their self-concepts. Participants Students in their first trimester and eighth trimester at the Los Angeles College of Chiropractic during the 1993 academic year (n=158). Methods Peterson-Yaakobi Q-Sort, National Assessment of Educational Progress, two-tailed T-test, one way analysis of variance and Spearman-rho correlation. Results The majority of students have positive self- concepts as science students and although there was a difference between the 2 trimesters, it was not significant. As a group they generally had less exposure to science compared to undergraduates from a selected science program. Variables of socio-economic status, undergraduate major, and highest completed level of education did not statistically affect their self-concept. Conclusion Chiropractic students had the self-concept that enables them to subscribe to the philosophical foundations of science and better engage in basic sciences and, later, science-based clinical research. Knowledge of this self- concept can be used in the development of a more rigorous basic science curricula and clinical research programs at chiropractic colleges with the ultimate goal of providing a more firm scientifically based foundation for the profession.

Andre, Christine; Deerin, Jessica; Leykum, Luci

2017-05-02

Effective mentoring is an important component of medical student professional development. We provide a description of the mentoring program at our institution. Our institution UTHSCSA implemented a student-advising program (Veritas) with clinical faculty mentors and senior students (MiMs). The MiMs provided vertical peer mentoring to more junior students as an adjunct to faculty advising. The MiMs lead small group discussions that foster camaraderie, share academic and career information and promote professional identity. An optional MiM elective more intensively develops mentorship and leadership skills through a formal curriculum. The authors used annual survey data of all students as well as student mentors to evaluate program effectiveness. Overall, student perception of the program improved each year across multiple domains, including feeling more prepared, supported and satisfied with their overall experience in medical school. Student mentors also found the process rewarding and helpful to their future careers as physicians. The authors suggest implementing a vertical peer-mentoring program can be an effective adjunct to faculty mentoring.

Evaluate chemical and behavioural dependence of medical students, and compare it to a control group (students in non-medical faculties), in order to underline the harmful effect of university on medical students' dependence. A three-part questionnaire was distributed to a sample of 140 medical students at the Saint-Joseph university of Beirut (USJ), and to 140 students in many other USJ faculties, and filled in anonymously. The first part is about demographic criteria and the second and third parts are respectively about chemical and behavioural dependence, based on DSM IV criteria. There is no statistically significant difference between the two studied populations concerning the dependence on alcohol, cannabis, sedatives, opiates, amphetamines, workaholism, gambling and Internet. However, the prevalence of addiction to caffeine, cocaine, nicotine; sexual addiction, and compulsive buying are significantly lower in medical students when compared to the control group. Men, compared to women, did not show significantly higher levels of dependence on chemical substances. Workaholism is not significantly more prevalent in women. Sexual addiction and compulsive buying are not significantly higher in men. However, pathological gambling and Internet addiction are significantly more prevalent in men. Finally, this study does not show a variation in dependence through the years of medical studies. Most studies show that medical students have high levels of dependence on alcohol, opiates and sedatives. The results of our study show greater dependence on caffeine followed by nicotine, alcohol and sedatives. Medical students in our population did not reveal higher dependence rates compared to other university students. Overall, substance addiction in medical students may be related to the stress of medical studies, and easy access to drugs and prescriptions. These factors may be balanced by perfectionist traits, ethical standards and knowledge of adverse effects seen in

BioEYES, a nonprofit outreach program using zebrafish to excite and educate K-12 students about science and how to think and act like scientists, has been integrated into hundreds of under-resourced schools since 2002. During the week-long experiments, students raise zebrafish embryos to learn principles of development and genetics. We have analyzed 19,463 participating students' pre- and post-tests within the program to examine their learning growth and attitude changes towards science. We found that at all grade levels, BioEYES effectively increased students' content knowledge and produced favorable shifts in students' attitudes about science. These outcomes were especially pronounced in younger students. Having served over 100,000 students, we find that our method for providing student-centered experiences and developing long-term partnerships with teachers is essential for the growth and sustainability of outreach and school collaborations.

The paper presents the results of a case study that explores the potentials of weblogs and social bookmarking to support transparency in a university course. In the course, groups of students used weblogs and social bookmarking in their work. The objective of the case was to empower students...... by providing them with tools that would be visible to the other students in the course, thus, making students’ ideas, thoughts and questions visible to the other students in the course. The paper concludes that use of digital media for transparency can support empowerment of students and inspiration among...... students in a course, but that the challenge is to create a balance between personal tools and tools for collaborative group work that are also suitable for transparency between students....

Student-generated reading questions: diagnosing student thinking with diverse formative assessments.

Offerdahl, Erika G; Montplaisir, Lisa

2014-01-01

Formative assessment has long been identified as a critical element to teaching for conceptual development in science. It is therefore important for university instructors to have an arsenal of formative assessment tools at their disposal which enable them to effectively uncover and diagnose all students' thinking, not just the most vocal or assertive. We illustrate the utility of one type of formative assessment prompt (reading question assignment) in producing high-quality evidence of student thinking (student-generated reading questions). Specifically, we characterized student assessment data using three distinct analytic frames to exemplify their effectiveness in diagnosing student learning in relationship to three sample learning outcomes. Our data will be useful for university faculty, particularly those engaged in teaching upper-level biochemistry courses and their prerequisites, as they provide an alternative mechanism for uncovering and diagnosing student understanding. © 2013 by The International Union of Biochemistry and Molecular Biology.

Full Text Available We examine differences between college students and non-students with respect to orientation toward e-cigarettes. Participants were U.S. adults 18-24 (465 students, 409 non-students. Data collection employed an online survey by GfK Custom Research. Smoking, vaping, and use of alternate tobacco were assessed, as were variables from the Theory of Reasoned Action and Diffusion of Innovations. This study showed that smoking status largely explains use and orientation toward electronic cigarettes among both students and non-students, with differences attributable to higher smoking rates among non-students. Results also showed that among student smokers there was a greater level of information exposure concerning electronic cigarettes, and more prevalence in the use of alternate tobacco. Hookah use in that group was significantly greater than for non-student smokers. Together these findings suggest that students may be more vulnerable to electronic cigarette use due to higher related information exposure and the integration of vaping into hookah culture.

Student Autonomy and its Effects on Student Enjoyment in a Traditional Mechanics Course for First-Year Engineering Students

In light of recent literature in educational psychology, this study investigates instructional support and students' autonomy at a small technical undergraduate school. Grounded theory is used to analyze twelve semi-structured open-ended interviews about engineering students' experiences in Introductory Mechanics that includes Lecture, Recitation, and Laboratory components. Using data triangulation with each course component as a unit of analysis, this study examines students' course enjoyment as a function of instructional support and autonomy. The Lecture utilizes traditional instructor-centered pedagogy with predominantly passive learning and no student autonomy. The Recitation creates an active learning environment through small group work with a moderate degree of autonomy. The Laboratory is designed around self-guided project-based activities with significant autonomy. Despite these differences, all three course components provide similar levels of instructional support. The data reveal that students enjoy the low autonomy provided by Lecture and Recitations while finding the Laboratory frustrating. Analyses indicate that the differences in autonomy contribute to students' misinterpretation of the three course components' value within the context of the entire course.
