Beyond Damage-Centered Teacher Education: Humanizing Pedagogy for Teacher Educators and Preservice Teachers

Background/Context In our best efforts to increase preservice teachers’ critical consciousness regarding the historical and contemporary inequities in the P–12 educational system and equip them to embody pedagogies and practices that counter those inequities, teacher educators often provide curricular and field experiences that reinforce the deficit mindsets that students bring to the teacher education classroom. For many social justice-oriented teacher educators, our best intentions to create humanizing experiences for future teachers can have harmful results that negatively impact preservice teachers’ ability to successfully teach culturally diverse students in a multitude of learning contexts. Purpose/Objective/Research Question/Focus of Study In this article, we propose a humanizing pedagogy for teacher education that is informed by our experiences as K–12 teachers and teacher educators in a university-based teacher preparation program. We focus on the general questions, How can university-based teacher preparation programs embody and enact a humanizing pedagogy? and What role can curriculum play in advancing a humanizing pedagogy in university-based teacher preparation programs? Research Design In this conceptual article, we theorize a humanizing pedagogy for teacher education and propose a process of becoming asset-, equity-, and social justice-oriented teachers. This humanizing pedagogy represents a strengths-based approach to teaching and learning in the teacher preparation classroom. Conclusions/Recommendations We propose core tenets of a humanizing pedagogy for teacher education that represent an individual and collective effort toward critical consciousness for preservice teachers and also for teacher educators. If university-based teacher education programs are committed to cultivating the development of asset-, equity-, and social justice-oriented preservice teachers, the commitments to critical self-reflection, resisting binaries, and enacting ontological and epistemological plurality need to be foundational to program structure, curricula alignment, and instructional practice.
Vibrational Raman and Raman optical activity spectra of D-lactic acid, D-lactate, and D-glyceraldehyde: Ab initio calculations

Vibrational Raman and Raman optical activity (VROA) spectra have been obtained ab initio for various conformations of d-lactic acid, d-lactate, and d-glyceraldehyde. The calculations have been carried out at the linear response self-consistent field level. The VROA spectra have been found to be very sensitive to the conformational changes. The VROA parameter of the stretching vibration of the carbonyl group is shown to be a promising parameter for structural investigations because it changes sign when a short internal hydrogen bond OH···OC is formed. Raman spectra do not exhibit such sensitivity to the molecular conformation, although an analysis of the stretching vibrations of the hydroxyl group can also be helpful in localizing internal hydrogen bonds.
Caracterização da fração lipídica de amostras comerciais de camarão-rosa

The objective of this study was to describe the fresh cooled pink-shrimp (Penaeus brasiliensis and Penaeus paulensis) lipid. The total lipid content was 1.13 +/- 0.09 g/100 g while fatty acid profile showed 32.9% saturated, 20.4% monounsaturated and 40.5% polyunsaturated. Eighteen fatty acids were detected, seven saturated (14:0, 15:0, 16:0, 17:0, 18:0, 20:0, 22:0), four monounsaturated (16:1w7, 17:1w9, 18:1w9, 20:1w9) and seven polyunsaturated (18:2w6, 18:3w3, 20:2w6, 20:4w6, 20:5w3, 22:5w3, 22:6w3). The free cholesterol content was 92 to 136 mg/100 g with average of 118 mg/100 g. In same time, was observed the occurrence of free 7-ketocholesterol, a product of cholesterol oxidation, in levels of 0.185 to 0.366 microgram/g. The fatty acid profile was obtained by gas chromatography with a fused silica column Supelcowax 10. The cholesterol and 7-ketocholesterol was determined by high performance liquid chromatography using a mu-Porasil column, normal phase, and a diode array detector.
Growth and 4-Ethylphenol Production by the Yeast Pichia guilliermondii in Grape Juices

The behavior of Pichia guilliermondii strains producing high levels of 4-ethylphenol in synthetic media was studied in wines and grape juices. These strains lost their viability and did not produce 4-ethylphenol after 24 hr of inoculation in red wines with ethanol adjusted to 10 or 12% (v/v) and pH 3.5 in the absence of free sulfite. Under the same conditions, at 12% (v/v) ethanol, growth of Dekkera bruxellensis was observed. When grown in single culture in grape juices, selected strains of P. guilliermondii produced high levels of 4-ethylphenol. In mixed grape juice fermentations with Saccharomyces cerevisiae , P. guilliermondii began to die after starter inoculation at 10 7 cfu/mL and did not produce 4-ethylphenol. Low starter inoculation rates (10 2 cfu/mL) added 72 hr after P. guilliermondii inoculation resulted in high production of 4-ethylphenol. In conditions mimicking cold prefermentative maceration processes, at 10°C for 72 hr, P. guilliermondii did not grow, while at 25°C growth attained a 10 4 -fold increase. At this temperature, addition of 200 mg/L potassium metabisulfite after grape crushing did not eliminate P. guilliermondii inoculated at 10 4 cfu/mL in grape juice of pH 3.57. The possibility that high levels of 4-ethylphenol in wines are due to the activity of P. guilliermondii should be mostly related with uncontrolled growth in contaminated grape juices before starter inoculation. In wines, its ability to produce 4-ethylphenol seems to be much lower than that of D. bruxellensis .
Photochemistry and vertical mixing

Earth-based observations relevant to the question of photochemistry and vertical mixing are discussed. Phytolysis of methane, the only known photochemically active volatile in the Uranian atmosphere, produces heavier hydrocarbons, the most abundant of which are ethane, acetylene, and the polyacetylenes. Unlike Jupiter and Saturn, these hydrocarbon products condense at the low temperatures prevalent in the middle atmosphere. Contrary to the pre-Voyager notion that the atmosphere of Uranus is remarkable clear, it is found that the aerosols are widely and extensively distributed. Despite its photodestruction, methane remains stable in the Uranian atmosphere. The vertical mixing on Uranus is found to be the least efficient of any of the planetary atmospheres.
Molecular phylogenetic systematics in the Dendrobiinae (Orchidaceae), with emphasis on Dendrobium section Pedilonum

Clements, M.A. (Centre for Plant Biodiversity Research, Australian National Herbarium, G.P.O. Box 1600, Canberra, A.C.T. 2601, Australia) 2003. Molecular phylogenetic systematics of the Dendrobiinae (Orchidaceae), with emphasis on Dendrobium section Pedilonum. Telopea 10(1): 247–298. Molecular systematic research using the internal transcribed spacer (ITS) region of the 18–26S nuclear ribosomal DNA repeat unit, on representatives of most taxonomic units within the Dendrobiinae has provided independent support, in addition to morphological and biological data, for the phylogenetic reassessment of the taxon. At a broad level, the Dendrobiinae is polyphyletic with Epigeneium forming an independent clade; Dendrobium section Oxystophyllum is deeply embedded within one of the outgroups, subtribe Eriinae: Podochileae; and the remaining taxa isolated into two major groups, viz the Asian and Australasian clades. A detailed study of part of the Asian clade, with emphasis on representatives of the morphologically based Dendrobium section Pedilonum, groups species into seven major clades. Dendrobium section Pedilonum is shown to be non-monophyletic with most species previously interpreted as belonging to it being well isolated from D. secundum, the designated type of that taxon, and interspersed amongst representatives of D. section Calcarifera, Calyptrochilus, Cuthbertsonia, Dendrobium, Dolichocentrum, Oxyglossum and Platycaulon. Dendrobium section Rhopalanthe, which separates the two major clades containing representatives of D. section Pedilonum, is itself paraphyletic with representatives of sections Aporum and Bolbidium embedded within it. These molecular results, combined with morphological data, provide a strong basis for a reassessment of the phylogeny of part of the study taxon. A reclassification of this part of the Dendrobieae and Podochileae is provided in Appendix 2, including: re-instatement of the genus Oxystophyllum (Eriinae: Podochileae); the recognition and description of subtribes Epigeneiinae and Grastidiinae (Dendrobieae); recognition or re-instatement of the genera Aporum, Callista, Ceraia, Coelandria, Eurycaulis, Distichorchis, Pedilonum as distinct from Dendrobium; the elevation of Anisopetala to generic status; and where necessary the transfer of the appropriate species from Dendrobium to these genera.
Extraction of some Hexavalent Actinide Ions from Nitric Acid Medium using Several Substituted Diglycolamides

Several substituted diglycolamides, namely TPDGA, THDGA, TODGA, and TDDGA, were evaluated in a comparative study on the extraction of hexavalent actinide ions such as UO22+, NpO22+, and PuO22+ from nitric acid medium. The acid extraction constants (KH) for the diglycolamides were determined to be 3.8 ± 0.6, 1.6 ± 0.1, 4.1 ± 0.4, and 1.4 ± 0.2 for TPDGA, THDGA, TODGA, and TDDGA, respectively. Though metal ion extraction generally increased with increasing the feed acid concentration, the nature of the extracted species changed with aqueous-phase acidity. While complexes of the type MO2(NO3)2·nL (where L is the diglycolamide extractant and n is 1 and 2) were found to be extracted at 1 M HNO3, the average number of ligand molecules associated with the complex decreased to ˜1 when the nitric acid concentration increased to 3 M. These results have great significance from the actinide separation point of view, as the actinides ions can be made virtually inextractable by adjusting their oxidation state. The thermodynamic parameters were also calculated, which indicated spontaneous reactions with large exothermicities.
High-Temperature Proton-Conducting Lanthanum Ortho-Niobate-Based Materials. Part II. Sintering Properties and Solubility of Alkaline Earth Oxides

The sintering properties and microstructure of La1−xAxNbO4 powders (x=0, 0.005, and 0.02 and A=Ca, Sr, and Ba), prepared by spray pyrolysis have been investigated. Dense materials (>97%) were obtained by conventional sintering at 1200°C and by hot pressing (25 MPa) at 1050°C, respectively. Homogeneous materials were obtained and the average grain size obtained by the two densification methods was ∼2.0 and ∼0.4 μm, respectively, for the 2% doped materials. Pure lanthanum ortho-niobate (LaNbO4) showed a higher degree of grain growth. In the acceptor-doped materials, secondary phases were observed to inhibit grain growth at 1200°C. At 1400°C or higher, molten secondary phases in the Ba-doped materials resulted in severe grain growth, causing microcracking during cooling due to crystallographic anisotropy. A low solubility of AO (A=Ca, Sr, and Ba) in LaNbO4 is inferred from the presence of secondary phases, and 1 mol% solubility of SrO in LaNbO4 was found by electron microprobe analysis. The electrical conductivity in wet hydrogen of the materials demonstrated that the main charge carrier was protons up to 1000°C and reached a maximum value of ∼8·10−4 S/cm at 900°C.
Study of the Drying Kinetics of Green Bell Pepper and Chemical Characterization

Abstract The present work aimed, on one hand, the study of the drying of green peppers, in terms of drying kinetics evaluated at 30°C, 40°C, 50°C, 60°C and 70°C, having the experimental data been fitted to different empirical kinetic models from literature. This kinetic study was then complemented with the modelling in terms of Fick's diffusion equation. On the other hand, the chemical characterization in fresh and after drying at the lowest and highest temperatures was analysed, for evaluation of the effect of drying and drying temperature on the chemical composition of the product. In this way, the analyses made were: moisture content, sugar content, proteins, ash, fat, fibre and acidity. From the results obtained, it was concluded that the empirical models that best describe the dehydration kinetics were the Page and Newton models. From the experimental data was possible to estimate the diffusivities, which range between 9.0 × 10 −10 at 30°C and 8.0 × 10 −9 m 2 s −1 at 70°C. Moreover, it was verified that drying influences the chemical composition of the peppers, but, conversely, the influence of the drying temperature was not very significant.
Isolation And Identification Of Essential Oils From Cymbopogan Citratus (Stapf) Dc Using Gc-Ms And Ft-Ir

Citral is present in the oils of several plants, including lemon myrtle (90-98%), Litsea citrata (Blume.) (90%), Litsea cubeba (Louv.) (70-85%), lemongrass Cymbopogon Citratus (stapf) (65-85%), lemon tea-tree (70-80%), Ocimum gratissimum (L) (66.5%), Lindera citriodora (Siebold and Zucc) (about 65%), Calypranthes parriculata (about 62%), petit grain (36%), lemon verbena (30-35%), lemon ironbark (26%), lemon balm (11%), lime (6-9%), lemon (2-5%), and orange . Citral, present in lemon grass, is used as a flavor and for fortifying lemon oil. This study involved isolation of essential oil from samples of lemon grass grown in Thika, Kiambu County, using hydro distillation and in comparison with correlation charts, functional groups present determined using FT-IR in the fingerprint region. The results obtained from hydro distillation indicated that the percentage yield of oil extracted is higher on dried leaf samples as compared to freshly cut leaves. The spectra obtained from GC-MS was used for relative quantification of various chemical constituents of the oil. Key words : correlation charts, functional groups, FT-IR, GC-MS,
Thermodynamic Study of Molten Si-Ti Binary Alloys

The thermodynamic properties of the Si-Ti system were studied by the Langmuir effusion method for alloys containing 0 ∼ 58.7mass%Ti. Molten samples were held in a water-cooled copper crucible and heated by power from an electron beam inside a vacuum chamber. Weight changes before and after the evaporation were measured to calculate the rate of evaporation. Evaporating species were also monitored by a mass spectrometer. The vapor pressure of titanium was much lower than that of silicon in the molar composition range of this study. The vapor pressure of silicon was calculated using the Knudsen-Hertz equation. The thermodynamic properties of titanium were calculated by the Gibbs-Duhem equation and integral excess free energy of the Si-Ti system in the above composition range and between 1873-1948K were estimated.
Stress and the hypothalamus-pituitary-gonadal axis in the cyclic rat.

Plasma profiles of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were measured during restraint stress on the day of pro-oestrus; these profiles were considered in relation to ovulation rate on the next day. Rats bearing a permanent jugular vein cannula were subjected to restraint which was started 0, 1 or 2 h before the presumed onset of the LH surge and ended just before the beginning of the dark period. Exposure to restraint resulted in a suppression of the secretion of both gonadotropins on the day of pro-oestrus. Suppression of the LH surge was virtually complete (plasma LH < 0.2 ng/ml) in 1 5 out of 32 stressed rats, and the ovaries of these rats contained graafian follicles with oocytes in germinal vesicle stage. In these rats, the LH surge did not occur 24 h later. In the remaining 17 rats, restraint resulted in a considerable suppression of the LH surge. Of these rats, 5 had an ovulation rate of 100% and 4 ovulated partially. In unruptured follicles of the latter, the oocyte had not resumed meiosis and the follicle wall was not luteinized. In the remaining 8 rats with a reduced LH surge, ovulations had not occurred and graafian follicles were unaffected. The results of this study indicate that during pro-oestrus restraint stress suppresses and does not delay the release of preovulatory gonadotropins. Partial suppression of LH by restraint does not result in induction of meiotic resumption without subsequent ovulation or in luteinized unruptured follicles.
Density and temperature measurement of OH radicals in atmospheric-pressure pulsed corona discharge in humid air

Plasma application for environmental improvement is desirable, and it is worthwhile to clarify the behavior of OH radicals in nonthermal plasma. Under atmospheric-pressure humid air, the time evolutions and spatial distribution of relative density and rotational temperature of OH radicals are measured in pulsed positive corona discharge using laser-induced fluorescence with a tunable optical parametric oscillator laser. The density of OH radicals generated by discharge when 28 kV is applied is estimated to be about 1×1015cm-3 at 3 μs after discharge. The OH density increases with humidity. The rotational temperature rises after discharge. The rate of temperature rise increases with humidity. This phenomenon arises from fast vibration-to-translation energy relaxation of H2O. The spatial distributions of OH rotational temperature indicate that the temperature rises in the secondary streamer channel.
Influence of Electrode Material on Oxygen Overvoltage: A Theoretical Analysis

Variations of overvoltage for oxygen evolution from one metal to another primarily result from variations in the energy of the bond M–OH. The overvoltage decreases approximately in a linear manner with increasing bond energy. This relationship is verified experimentally for Ag, Au, Cd, Co, Cu, Fe, Ni, Pb, Pd, and Pt, for electrolysis in one N potassium hydroxide at one amp cm—2; the experimental data are those reported by Hickling and Hill. Bond energies for M–OH are calculated by three different thermodynamic cycles involving, respectively, the standard heat contents of the hydroxide, the oxide, and spectroscopic data for molecules MO. Variations of the energy of the bond M–OH, as the electrode is oxidized to a higher valence, also account for sudden breaks in plots of overvoltage against logarithm of current density. Finally, there is essentially no correlation between the oxygen overvoltage for different metals and the corresponding work functions.
HETEROSIS AND COMBINING ABILITY THROUGH LINE × TESTER ANALYSIS FOR YIELD, OIL AND MID OR HIGH OLEIC ACID CHARACTERS IN SUNFLOWER (Helianthus annuus L.)

This research was conducted in the southern Marmara region of Turkey during 2017-2018 growing season in order to determine general combining abilities (GCA) of parental lines, specific combining abilities (SCA) of hybrids, and estimate performance and the genetical structure of hybrid population obtained from three cytoplasmic male sterile (CMS) and four restorer lines with mid or high oleic acid content. The field experiments were designed in a Randomized Complete Block with three replications. According to the results, male parents AGR2 and AGR4 considered as good general combiners for developing increased seed and oil yields in sunflower hybrids, although there were not good general combiners in female parents for the same traits. CMS3 x AGR4 test hybrid, which has high oleic acid content, has been determined to be a promising hybrid variety candidate with its high seed and oil yields, high oil content and oleic acid content. However, although the SCA effects of CMS1 x AGR2 and CMS3 x AGR2 test hybrids were not significant for seed and oil yields, it was concluded that they were promising hybrids with high yield, oil content and mid oleic acid content. It was determined that both additive and non-additive gene effects were effective for yield and some important yield components in the hybrid population studied. The values of heterosis and heterobeltiosis values ranged from 10.8 to 728.9 % and -20.1 to 608.8 % for seed yield, respectively. Similarly, positively high and significant heterosis and heterobeltiosis values were obtained in the oil yield.
Electrochemical supercapacitor development based on electrodeposited nickel oxide film

A nickel oxide (NiO) electrode has been synthesized electrochemically, which is envisaged for supercapacitor application. The structural, morphological, and phase-purity confirmation studies of NiO films were undertaken using X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy, and contact angle measurements. Films of NiO were amorphous in phase, as there were no reflecting planes in the X-ray diffraction pattern. The presence of characteristic bands in FTIR and X-ray photoelectron spectroscopy analysis corroborated the NiO structure. The NiO film surface was smooth with very fine elongated particles (∼70 nm) and hydrophilic in character (57°). The supercapacitive performance of an NiO electrode tested using cyclic voltammetry measurement in 0.5 M Na2SO4 electrolyte within the potential range of −1.2 to +1.2 V demonstrated a specific capacitance as high as 458 F g−1 at 5 mV s−1. The obtained specific energy, specific power and Coulomb efficiency of NiO electrode were 10.90 W h kg−1, 0.89 kW kg−1, and 98%, respectively.
Age changes in the tunica intima of the aorta in goat ( Capra hircus )

Age changes in the aortic tunica intima may explain the higher prevalence of atherosclerosis among the elderly. Goat is a suitable model for the study of cardiovascular disease but the age changes in its aortic tunica intima are unreported. This study therefore examined structural changes that occur in the tunica intima of its aorta. Six healthy goats three aged over 60 months, and three aged less than 12 months, were used in this study. The animals were euthanized with sodium pentabarbitone and specimens taken from the various segment of the aorta studied by light microscopy and transmission electron microscopy. Materials for light microscopy were fixed 10% formaldehyde solution, processed for paraffin embedding and 7 micron sections stained with Mason’s Trichrome and Weigert’s Resorcin Fuchsin/Van Gieson stains. Those for transmission electron microscopy were fixed in 3% phosphate buffered glutaraldehyde solution, post fixed in osmium tetroxide and prepared for durcupan embedding. Ultrathin sections were stained with uranyl acetate, counterstained with lead citrate and examined by EM 201 phillips© electron microscope. Observations reveal that aging is characterized by endothelial discontinuities, presence of lymphocytes and dendritic cells in the tunica intima, subendothelial thickening, vacuolation and disintegration of internal elastic lamina. It is concluded that the intimal breaches observed in intimal aging may promote ingression of macromolecules into the vessel wall, and underpin the higher prevalence of atherosclerosis among the elderly. Control of serum atherogenic molecules should be enhanced in this age group. Keywords: Age, Tunica Intima, Aorta, Atherosclerosis
