School Climate and Social-Emotional Learning: Predicting Teacher Stress, Job Satisfaction, and Teaching Efficacy.

The aims of this study were to investigate whether and how teachers' perceptions of social-emotional learning and climate in their schools influenced three outcome variables--teachers' sense of stress, teaching efficacy, and job satisfaction--and to examine the interrelationships among the three outcome variables. Along with sense of job satisfaction and teaching efficacy, two types of stress (workload and student behavior stress) were examined. The sample included 664 elementary and secondary school teachers from British Columbia and Ontario, Canada. Participants completed an online questionnaire about the teacher outcomes, perceived school climate, and beliefs about socia-emotional learning (SEL). Structural equation modeling was used to examine an explanatory model of the variables. Of the 2 SEL beliefs examined, teachers' comfort in implementing SEL had the most powerful impact. Of the 4 school climate factors examined, teachers' perceptions of students' motivation and behavior had the most powerful impact. Both of these variables significantly predicted sense of stress, teaching efficacy, and job satisfaction among the participants. Among the outcome variables, perceived stress related to students' behavior was negatively associated with sense of teaching efficacy. In addition, perceived stress related to workload and sense of teaching efficacy were directly related to sense of job satisfaction. Greater detail about these and other key findings, as well as implications for research and practice, are discussed
Linear Elastic Fracture Mechanics Approach to Plate End Debonding in Rectilinear and Curved Plated Beams

This paper proposes a linear elastic fracture mechanics approach for the prediction of plate end debonding in rectilinear and curved plated beams. The analytical model results in simple equations, suitable for immediate design use. The load-deflection curve of a plated beam, from the onset of debonding up to the complete separation of the plate, is obtained by controlling the length of the interfacial debonding crack. Its shape clearly shows that snap-back or snap-through instabilities may arise when the beam is loaded under displacement or force control. Analytical predictions are also compared with finite element results based on an interfacial cohesive crack model. It is shown that the predictions of the proposed analytical model match closely the numerical solution, provided that an effective crack length accounting for the size of the fracture process zone is used in the calculations.
Elemental Abundances of Ultra-Heavy GCRs measured by SuperTIGER and ACE-CRIS and the Origin of Galactic Cosmic Rays

The Super Trans-Iron Galactic Element Recorder (SuperTIGER) long-duration balloon instrument and the Cosmic Ray Isotope Spectrometer (CRIS) on the NASA Advanced Composition Explorer (ACE) satellite have measured the abundances of galactic cosmic-ray elements from _(10)Ne to _(40)Zr with high statistics and single-element resolution. SuperTIGER launched from Williams Field, McMurdo Station, Antarctica, on December 8, 2012, flying for a record 55 days. During that flight we detected ∼1,300 nuclei with atomic number Z ≥ 30. The resolution in charge (Z) of SuperTIGER is excellent, with σ_Z ≈ 0.16 c.u. at _(26)Fe. SuperTIGER is sensitive to nuclei with energy at the top of the atmosphere of E > 0.8 GeV/nucleon. The instrument has now been recovered and preparations are underway for its next flight. ACE/CRIS has been taking data in space for more than 17 years since launch in 1997, has collected ∼625 nuclei with atomic number Z ≥ 30, and shows excellent resolution with clear separation between the charges for 30 ≤ Z ≤ 40. ACE/CRIS is sensitive to nuclei in the energy range 150 ≤ E ≤ 600 MeV/nucleon. Preliminary results from the balloon-borne SuperTIGER show good agreement with ACE measurements in space, validating our corrections to SuperTIGER abundances for nuclear interactions in the atmosphere. The results from these experiments will be discussed in the context of the OB association model for the origin of galactic cosmic rays. Future missions to measure elemental abundances to higher Z, the SuperTIGER-II LDB instrument and the orbiting Heavy Nuclei eXplorer (HNX) mission, will also be discussed.
Comparison of Semi-aquatic Snake Communities Associated with the Khorat Basin, Thailand

The Khorat Basin is a prominent geographic feature of Indochina, potentially important in the ecology and evolution of semi-aquatic snake communities. We compared community structure and population characteristics of semi-aquatic snakes (taxonomic focus on homalopsine snakes) from localities located in the Khorat Basin, on the mountainous rim of the Khorat Basin, and at lower elevation sites located outside of the Khorat Basin. Species richness of semi-aquatic snakes assemblages was comparable in and outside of the Khorat Basin (8 species). There was a high degree of species overlap between assemblages found in and out of the basin (coefficient of similarity = 0.88), but species diversity was higher in the Khorat Basin (evenness = 0.694). Enhydris enhydris was the strong dominant at sites located outside of the basin (evenness = 0.334). Homalopsine snakes were absent from the Khorat Basin rim sites. Snakes were over twice as abundant at sites located outside of the Khorat Basin compared to sites in the basin. We found size sexual dimorphism for E. enhydris outside of the Khorat Basin, but not in the basin. Female snakes (E. enhydris and E. plumbea) from sites outside the Khorat Basin were larger and heavier in comparison to Khorat Basin populations. We discuss historical, biogeographical, biotic, and abiotic factors that may contribute to the observed differences.
Geographic variation in allozymes of populations of Salamandra salamandra (Amphibia: Urodela) exhibiting distinct reproductive modes

The populations of the urodele Salamandra salamandra in the Northern Iberian Peninsula exhibit very different coloration patterns and a remarkable range in reproductive modes (from giving birth to a large number of aquatic larvae to a parturition event of just a few fully metamorphosed, i.e. terrestrial, offspring). Electrophoretic study of geographic variation in allozymes shows that this extraordinary diversity, particularly in reproductive modes, is not accompanied by a genetic differentiation of similar magnitude. All the populations sampled along a transect crossing the Northern part of the Iberian Peninsula and encompassing the various reproductive strategies, as previously described, can be ascribed to a single species, because of small interpopulational genetic distances (ranging DNei from 0.05 to 0.199) and absence of fixed (diagnostic) alleles. A variety of phenetic and cladistic methods were used to elucidate the relationship among populations, based on allozyme data. These methods defined two well corroborated clusters: the first contains populations of salamanders with a blotched dorsal coloration pattern and characterized by parturition of aquatic larvae; the second group is composed of populations exhibiting a striped dorsal coloration pattern, smaller adult body size, and giving birth to fully metamorphosed terrestrial offspring. The latter group also encompasses some populations where mixed parturition events, which include both larvae and metamorphosed offspring, which have been recorded (Dopazo and Alberch, 1994). The absence of a correlation between genetic and geographic distance suggests that the mode of differentiation of the species is based on at least two successive events of isolation, radiation, and secondary contact between populations. Furthermore, the validity of the described “subspecies” is questioned by our data, which point out the need for a detailed systematic study of Salamandra from a global perspective. “Viviparity”, here meaning giving birth to fully metamorphosed offspring, originated once and occurs as intraspecific, and even as intrapopulational variation. Thus, we confirm a system where a major evolutionary innovation ‐the acquisition of independence from the aquatic media in the primitive amphibian complex life cycle‐, can be studied at the microevolutionary, i.e., intra‐ and inter‐populational level.
Title Diurnal Variability of Tropical Rainfall Retrieved from Combined GOES and TRMM Satellite Information Permalink

Recent progress in satellite remote-sensing techniques for precipitation estimation, along with more accurate tropical rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and precipitation radar (PR) instruments, have made it possible to monitor tropical rainfall diurnal patterns and their intensities from satellite information. One year (August 1998–July 1999) of tropical rainfall estimates from the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) system were used to produce monthly means of rainfall diurnal cycles at hourly and 18 3 18 scales over a domain (308S–308N, 808E–108W) from the Americas across the Pacific Ocean to Australia and eastern Asia. The results demonstrate pronounced diurnal variability of tropical rainfall intensity at synoptic and regional scales. Seasonal signals of diurnal rainfall are presented over the large domain of the tropical Pacific Ocean, especially over the ITCZ and South Pacific convergence zone (SPCZ) and neighboring continents. The regional patterns of tropical rainfall diurnal cycles are specified in the Amazon, Mexico, the Caribbean Sea, Calcutta, Bay of Bengal, Malaysia, and northern Australia. Limited validations for the results include comparisons of 1) the PERSIANN-derived diurnal cycle of rainfall at Rondonia, Brazil, with that derived from the Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE) radar data; 2) the PERSIANN diurnal cycle of rainfall over the western Pacific Ocean with that derived from the data of the optical rain gauges mounted on the TOGA-moored buoys; and 3) the monthly accumulations of rainfall samples from the orbital TMI and PR surface rainfall with the accumulations of concurrent PERSIANN estimates. These comparisons indicate that the PERSIANN-derived diurnal patterns at the selected resolutions produce estimates that are similar in magnitude and phase.
Connectedness among five European sport horse populations - aspects on ID recording and exchange of pedigree data

While investigating the genetic ties between five European studbooks in order to check the feasibility of international genetic evaluation of sport horses, difficulties related to ID-numbers of stallions were encountered. It turned out that the original ID-number of a stallion was very seldom registered when he was used in breeding in another studbook area than his studbook of birth. To determine the extent of genetic ties among the horse populations the concept of genetic similarity (GS) was employed. This measures the number of tested horses sired by stallions with progeny in two organisations in relation to the total number of tested animals in those two organisations. Data on sport horse populations were provided from Denmark (DWB), Hanover (HAN), Holstein (HOLST) the Netherlands (KWPN) and Sweden (SWA), including 2381 stallions which together had 64225 progenies in these five populations. The GS values varied between 7 % (NLD and SWE) and 29 % (HAN and NLD). The average GS value among the horse populations was 15 %. This is almost twice as high as has previously been reported for major dairy cattle breeds. Considering these results international genetic evaluations of sport horses seem feasible. However, a major obstacle is the lack of unique ID numbers of horses across countries.
Shareholder Value Creation in European M&As

This Paper looks at the value generated to shareholders by the announcement of mergers and acquisitions involving firms in the European Union over the period 1998-2000. Cumulative abnormal shareholder returns due to the announcement of a merger reflect a revision of the expected value resulting from future synergies or wealth redistribution among stakeholders. Target firm shareholders receive on average a statistically significant cumulative abnormal return of 9% in a one-month window centred on the announcement date. Acquirers’ cumulative abnormal returns are null on average. When distinguishing in terms of the geographical and sectoral dimensions of the merger deals, our main finding is that mergers in industries that had previously been under government control or that are still heavily regulated generate lower value than M&A announcements in unregulated industries. This low value creation in regulated industries becomes significantly negative when the merger involves two firms from different countries and is primarily due to the lower positive return that shareholders of the target firm enjoy upon the announcement of the merger. This evidence is consistent with the existence of obstacles (such as cultural, legal, or transaction barriers) to the successful conclusion of this type of transaction, which lessen the probability of the merger actually being completed as announced and, therefore, reduce its expected value.
DEVICE AND TECHNIQUE FOR IN-SITU COATING OF THE RHIC COLD BORE VACUUM TUBES WITH THICK OFHC

To rectify the problems of electron clouds observed in RHIC and unacceptable ohmic heating for superconducting magnets that can limit future machine upgrades, we started developing a robotic plasma deposition technique for in-situ coating of the RHIC 316LN stainless steel cold bore tubes based on staged magnetrons mounted on a mobile mole for deposition of Cu followed by amorphous carbon (a-C) coating. The Cu coating reduces wall resistivity, while a-C has low SEY that suppresses electron cloud formation. Recent RF resistivity computations indicate that 10 μm of Cu coating thickness is needed. But, Cu coatings thicker than 2 μm can have grain structures that might have lower SEY like gold black. A 15-cm Cu cathode magnetron was designed and fabricated, after which, 30 cm long samples of RHIC cold bore tubes were coated with various OFHC copper thicknesses; room temperature RF resistivity measured. Rectangular stainless steel and SS discs were Cu coated. SEY of rectangular samples were measured at room; and, SEY of a disc sample was measured at cryogenic temperatures.
Stimulation of Murine Intestinal Secretion by Daily Genistein Injections: Gender-dependent Differences

Background/Aims: The effect of daily injections with genistein (naturally occurring phytoestrogen) on intestinal chloride (Cl-) secretion was measured with Ussing chamber short circuit current (Isc, µA/cm2), in C57BL/6J male and female mice, using 600 mg/kg genistein/day (600G), 300 mg/kg genistein/day (300G), 150 mg/kg genistein/day (150G) or genistein-free vehicle control (0G) for 1- or 2-weeks. Methods and Results: Injecting with 600G elicited significant increases in basal Isc in females after 1-week (ñ70 µA/cm2, n=15, p < 0.05) and in males after 2-weeks (ñ80 µA/cm2, n=5, p < 0.05) compared to their 0G counterparts. Chloride-free ringer significantly reduced basal Isc by 65% in 600G males and 72% in 600G females, suggesting that Cl- was the major anion comprising the genistein-stimulated secretion. The forskolin-stimulated (10 µM) Isc was significantly inhibited by the CFTR chloride channel inhibitors, glibenclamide (500 µM) and CFTRinh-172 (100 µM) in 600G males and females, suggesting some contribution by genistein-dependent CFTR-mediated Cl- secretion. We found no associated changes in intestinal morphology, nor change in total CFTR protein with 600G. There was a 5% increase in apical/subapical ratio in 600G males compared to controls (no change in females). Conclusion: These data suggest that male and female mice both exhibit increased Cl- secretion with 600G, however, the mechanisms mediating this are gender-dependent.
Perception of community health extension services among women in a rural community in Ilorin East, Kwara State, Nigeria

Background : Rural women in developing countries, including Nigeria are faced with a number of health problems with very limited access to health care facilities. This study assessed the perception of women in rural areas on community health extension services in Ilorin, Kwara State. Methods : One hundred and twenty rural dwelling women were sampled from six rural communities selected by simple random sampling method. A structured questionnaire was used for data collection. Data was analyzed using SPSS version 18. Level of significance was set at p-value of ≤ 0.05. Results : The mean age of the respondents was 45 years and 69.3% of them were married. Over a third (36.7%) of the respondents, had no formal education and 40.0% were farmers with an average monthly income of ₦14,146.00. High awareness level on community health extension services was observed but 65.5% lived at a distance beyond 3 km from the health centers and they usually trek to the facilities. Maternal, child care services and first aid treatment were available; however, mental health was poorly ranked in terms of effectiveness of community health extension services provided in the area. Age (p<0.001) was inversely significant while educational level (r = 0.334, p < 0.01) was positively related to the frequency of availability of community health extension services. Conclusion : The respondents were aware of community health extension services, however, most of them live far from the health facilities. We recommend that Community Health Extension Workers should embark on home visits in order to improve access to health services in the rural communities. Keywords: Perception, Community Health Extension Services, Women
Influence of Increased Salinity on Physiological Responses of Hydroponic Grown Tomato (Lycopersicon esculentum Mill.)

Hydroponic cultures were used to evaluate salt stress responses in two (JO112 and JO992) tomato (Lycopersicon esculentum Mill.) genotypes. Hydroponic cultures were grown on media supplemented with 0, 50, 100, 150 and 200 mM NaCl and CaCl2 in equal molar ratio, growth and physiological traits were determined. Negative response had happened in growth parameters (FW (fresh weight), DW (Dry weight) and shoot height). Na+, Cl¯ and Ca+² ions and proline concentrations increased in both cultivars of hydroponically grown plants with increase in salinity. In contrast, K+ ions decreased with increase in salinity. Induced salinity significantly reduced (more negative) cell sap osmotic potential. The genotype JO992 generally had higher shoot and root fresh weight, dry weight, shoot height and root length than JO112. The results indicate that, in both genotypes, osmotic adjustment was achieved by means of Na+, Cl¯ and Ca+² ions uptake from the medium and by synthesis of proline.

Comparative Temporospatial Expression Profiling of Murine Amelotin Protein during Amelogenesis

Tooth enamel is formed in a typical biomineralization process under the guidance of specific organic components. Amelotin (AMTN) is a recently identified, secreted protein that is transcribed predominantly during the maturation stage of enamel formation, but its protein expression profile throughout amelogenesis has not been described in detail. The main objective of this study was to define the spatiotemporal expression profile of AMTN during tooth development in comparison with other known enamel proteins. A peptide antibody against AMTN was raised in rabbits, affinity purified and used for immunohistochemical analyses on sagittal and transverse paraffin sections of decalcified mouse hemimandibles. The localization of AMTN was compared to that of known enamel proteins amelogenin, ameloblastin, enamelin, odontogenic ameloblast-associated/amyloid in Pindborg tumors and kallikrein 4. Three-dimensional images of AMTN localization in molars at selected ages were reconstructed from serial stained sections, and transmission electron microscopy was used for ultrastructural localization of AMTN. AMTN was detected in ameloblasts of molars in a transient fashion, declining at the time of tooth eruption. Prominent expression in maturation stage ameloblasts of the continuously erupting incisor persisted into adulthood. In contrast, amelogenin, ameloblastin and enamelin were predominantly found during the early secretory stage, while odontogenic ameloblast-associated/amyloid in Pindborg tumors and kallikrein 4 expression in maturation stage ameloblasts paralleled that of AMTN. Secreted AMTN was detected at the interface between ameloblasts and the mineralized enamel. Recombinant AMTN protein did not mediate cell attachment in vitro. These results suggest a primary role for AMTN in the late stages of enamel mineralization.
What Can Deter Catering? Information Environment, Governance, and Agency Problem of Overvalued Equity

This study examines whether a better information environment or a strong governance system can deter catering and resolve agency problem of overvalued equity. Using U.S. data from 1987 to 2008, we find weak sensitivities of overvaluation with accruals and with capital investment for S&P 1500 firms, firms covered by more analysts, and large firms, where these firms are persuasively with better information environment. The finding is robust for alternative overvaluation measures and for a subsample of high turnover firms. We also find some evidence of a weaker negative relation of accrual and investment with future returns for firms with better information environment.
Production , Manufacturing and Logistics Environmental statistical process control using an augmented neural network classification approach

Shifts in the values of monitored environmental parameters can help to indicate changes in an underlying system. For example, increased concentrations of copper in water discharged from a manufacturing facility might indicate a problem in the wastewater treatment process. The ability to identify such shifts can lead to early detection of problems and appropriate remedial action, thus reducing the risk of long-term consequences. Statistical process control (SPC) techniques have traditionally been used to identify when process parameters have shifted away from their nominal values. In situations where there are correlations among the observed outputs of the process, however, as in many environmental processes, the underlying assumptions of SPC are violated and alternative approaches such as neural networks become necessary. A neural network approach that incorporates a geometric data preprocessing algorithm and identifies the need for increased sampling of observations was applied to facilitate early detection of shifts in autocorrelated environmental process parameters. Utilization of the preprocessing algorithm and the increased sampling technique enabled the neural network to accurately identify the process state of control. The algorithm was able to identify shifts in the highly correlated process parameters with accuracies ranging from 96.4% to 99.8%. 2005 Elsevier B.V. All rights reserved.
