The Mediator Role of Organizational Justice in the Relationship between Teachers’ Prejudices in their School Relations and Organizational Commitment: A Structural Equation Model

This study aims to test the theoretical model developed for the mediator role of organizational justice in the relationship between teachers’ prejudices in their school relations and organizational commitment levels. The research is designed using the survey model. The population comprised of teachers working at primary, secondary, and high schools in the Milas district of Mugla, Turkey, during the 2015-2016 academic year. The research sample comprised of 326 teachers selected through the disproportionate cluster sampling technique. The data for the research was collected through the Prejudices in School Relations Scale, Organizational Justice Scale, and the Organizational Commitment Scale. Pearson correlation coefficients were employed in terms of correlations between the variables observed during the research. The resulting model was tested using the Structural Equation Modeling (SEM). Research results show that teachers have a medium-level commitment, while their organizational justice perception is slightly over the medium level. Teachers are most prejudicial against managers and students, followed by parents, and least prejudicial against their colleagues. Teachers’ prejudices against their colleagues are relatively low, while their prejudices against managers, students, and parents are close to the medium level. In this research, it was determined that teachers’ organizational justice perception plays a mediator role between the variables of teachers’ prejudices in their school relations and their organizational commitment. The intermediation of organizational justice perception displays a suppression effect in the inversely proportional relationship between teachers’ prejudices and commitment.
Escaping Satiation Dynamics: Some Evidence from British Household Data

Summary The tendency of sectoral demand to satiate has long been argued to be a key driver of the structural change in an economy (Pasinetti 1981; Saviotti 2001). This literature raises the question as to what extent cross-sectional patterns of household expenditure can be used to make inferences about how the demand for goods and services will grow over time. Moreover, if indeed satiation does take place, then firms and entrepreneurs could react to this situation by innovating goods and services in order to overcome stagnation in demand growth (Witt 2001). We empirically investigate this ‘satiation-escape’ hypothesis by examining the inter-temporal dynamics of Engel curves and their derivatives, which reflect how household spending on a good changes with income. Taking into account changes in the price level, we investigate whether Engel curves that exhibit cross-section satiation tend to exhibit over time an upwards shift in the satiation level jointly with a shift in position and shape. Evidence suggests that this is actually the case.
Moving Finite Element Simulation of Various Fracture Path Prediction in Materials Containing Holes and Inclusions

Summary In thispaper, thesimulationsof fatiguecrack propagationand dynamicfracture pathpredictionarecarried outforspecimenscontainingcircularholesorinclusions, usingthemovingfiniteelement methodbasedonDelaunayautomatictriangulation. And, we compared the numerical results with the experimental results. In this study, we carried out fatigue and dynamic fracture path prediction sim- ulation containing circular holes or inclusions in materials. And this existence ex- amined the effect on the crack growth. The former of this paper part treats fatigue fracture problem, and the latter part treats dynamic fracture problem. The simulation was conducted using the moving finite element method based on Delaunay automatic triangulation (1,2), and the numerical results were com- pared with the each experiment results. In the fatigue fracture path prediction sim- ulation, Paris's law was used to decide crack propagation length Δa and fracture- path prediction procedure was used to decide crack propagation direction. In dy- namic fracture path prediction simulation, Mixed-Phase fracture path prediction mode simulation (3) that using crack velocity history that obtained by the experi- mental result and fracture path prediction procedure was used to reproduce.
Acquisition a Baseball-Pitch through Observation: What Information Is Extracted?

The purpose of the present study was to compare the relative effects of observing video, stick figure and point-light model demonstrations on acquisition a Baseball pitch. Participants (ns = 41) in demonstration and control groups performed 5 trials in pretest, three blocks of 10 trials in acquisition phase, and two retention tests of 5 trials in 10 minutes and one week later. Participants´ performances were assessed by two raters at the level of overall movement and individual movement phases. Results showed similarities between demonstration groups in acquisition phase and early retention test. Participants showed a significant improvement in stride and follow-through phases from pretest to acquisition blocks. The findings are discussed in terms of theoretical and methodological backgrounds.
Perturbation to global tropospheric oxidizing capacity due to latitudinal redistribution of surface sources of NOx, CH4 and CO

Economic and social projections indicate that during next several decades there will be major geographical redistribution of surface emissions of O3 precursors, such as NOx, CH4 and CO. A net decrease in their emissions from northern hemispheric mid‐latitudes will be accompanied by substantial increases from the tropics. We have investigated a hypothetical scenario of currently underway transition of such emission patterns using a global two‐dimensional photochemical model. With overall O3 precursor releases held constant, a simultaneous transfer of their emissions by 25% from the latitude belt 75°N–35°N to 5°S–35°N increases tropospheric oxidizing capacity such that the methane global lifetime and concentrations fall by more than 3%. Seasonally dependent changes in surface O3 concentrations are also calculated. In influencing OH concentration, redistribution of surface NOx emissions is 2–3 orders of magnitude more efficient per unit mass than CO emissions. Shifts in methane sources have insignificant effects on global photochemistry, but lead to a decrease in its interhemispheric gradient.
Ivf versus spontan singleton pregnancies fetal and maternal outcomes in a tertiary care hospital

Background: We aimed to compare perinatal outcomes of intracytoplasmicsperm injection (ICSI) versus naturally (spontaneously) concieved age and parity matched group of singleton pregnants. Methods: Two hundred and sixteen singleton pregnancies aged between 18-45 years old were included in this study. Among all study group, 106 cases were ICSI pregnancies (study group) and 110 cases were spontaneously concieved singleton pregnancies (control group). Pregnancy outcome parameters were: the incidence of chronic hypertension, preeclampsia, gestational hypertension, placenta previa, placental abruption, preterm birth, intrahepatic cholestasis of pregnancy, gestational diabetes, preterm premature rupture of membranes, caesarean delivery. Results: There were no differences in terms of maternal age, BMI, gravidity, parity, gestational weeks at birth and birth weight between ICSI and spontaneously concieved pregnancy groups. Placental abruption, gestational diabetes and cesarean section rates were significantly higher in ICSI pregnancies than spontaneously conceived pregnancies (4.7% vs 0%, 21.7% vs 11.8% and 82.1% vs 68.2%, respectively). There wereno statistically significant differences in terms of chronic hypertension, preeclampsia, gestational hypertension, preterm labor, placenta previa, intrahepatic cholestasis of pregnancy, preterm and term premature rupture of the membranes. Conclusion: ICSI pregnancies have higher adverse perinatal outcomes than spontaneously conceived singleton pregnancies which were matched with age and parity. That’s why ICSI pregnancies should be given a detailed counseling about the adverse perinatal outcomes and should be followed up more carefully through the pregnancy.
Polymorphism of the H-FABP, MC4R and ADD1 genes in the Meishan and four other pig populations in China

Genes such as the Heart Fatty Acid-Binding Protein (H-FABP), the Melanocortin-4 Receptor (MC4R) and the Adipocyte Determination and Differentiation factor-1 (ADD1) play an important role in meat quality in pigs. The Meishan is one of the most prolific pig breeds in the world, but it is in danger, in China, of being replaced by other exotic pig breeds because of its slow growth rate and high body fat content. To know their present genetic status, the polymorphism of the three genes in the Meishan and four other pig populations (Sutai, Yorkshire×Sutai, Landrace×Sutai and Duroc×Landrace×Yorkshire) in China was analysed, using PCR-RFLP and PCR-SSCP, and were further compared with each other. The results showed that gene and genotype frequencies differed significantly between the Meishan and the other four populations. This is suggested to be one of the reasons for the good meat quality of the Meishan compared to the other breeds. In addition, since half of the genetic background of Sutai is from the Meishan, results also indicated that marker assisted selection (MAS) is very important for the development of new pig breeds.

Oil Prices, Exchange Rate and Prices for Agricultural Commodities: Empirical Evidence from Russia

In this paper, we investigate long and short-term impact of changes in oil prices and the exchange rate on prices of seven groups of agricultural products in Russia (buckwheat, grain crops, potatoes, oat, wheat, rye, barley). In this paper, Granger causality approach is applied to test long-run interlinkages with monthly data from January 1999 to October 2015. For testing the response of agricultural prices to sudden shocks in oil prices and exchange rate in the short run, we use impulse-response techniques. The results of impulse response analysis show that agricultural prices are not particularly sensitive to changes in oil prices and the exchange rate of Russian ruble in the short term, except for imported commodities. In the long run, Granger causal relationship between agricultural prices and oil prices is missing, and with exchange rate is observed only in case of imported agricultural goods.
Estimation of Quasi-Rational DSGE monetary models

This paper proposes the estimation of small-scale dynamic stochastic general equilibrium (DSGE) monetary models under the quasi-rational expectations (QRE) hypothesis. The QRE-DSGE model is based on the idea that the determinate reduced form solution associated with the structural model, if it exists, must have the same lag structure as the ‘best fitting’ vector autoregressive (VAR) model for the observed time series. After discussing solution properties and the local identifiability of the model, a likelihood-based iterative algorithm for estimating the structural parameters and testing the data adequacy of the system is proposed. A Monte Carlo experiment shows that, even controlling for the omitted dynamics bias, the over-rejection of the nonlinear cross-equation restrictions when asymptotic critical values are used and variables are highly persistent is a relevant issue in finite samples. An application based on euro area data illustrates the advantages of using error-correcting formulations of the QRE-DSGE model when the inflation rate and the short-term interest rate are approximated as difference stationary processes. A parametric bootstrap version of the likelihood-ratio test for the implied cross-equation restrictions does not reject the estimated QRE-DSGE model.
Interplanetary magnetic field control of fast azimuthal flows in the nightside high‐latitude ionosphere

SuperDARN radar data from both hemispheres for the interval January 1999 to November 2006 have been inspected for evidence of high‐speed azimuthal flows in the nightside high‐latitude ionosphere. In the northern hemisphere, 88% of the westward directed fast flows occurred during IMF BY negative intervals and 83% of the eastward flows occurred during IMF BY positive intervals. In the southern hemisphere 82% of the westward flows occurred during IMF BY positive intervals and 74% of the eastward flows occurred during IMF BY negative intervals. ∼74% of these fast flows occurred when the IMF was within the 30° < ∣θ∣ < 100° clock angle range and the AE index was below 150 nT. These results support the hypothesis that highly dynamic magnetospheric activitycan be associated with predominantly northward, but BY‐dominated IMF driving conditions and subsequent non‐substorm reconnection in a twisted magnetotail.
An Exact Solution for Vibration Analysis of Soft Ferromagnetic Rectangular Plates Under the Influence of Magnetic Field with Levy Type Boundary Conditions

In this paper vibration of ferromagnetic rectangular plates which are subjected to an inclined magnetic field is investigated based on classical plate theory and Maxwell equations. Levy type solution and Finite element method using Comsol software are used to obtain the frequency of the plate subjected to different boundary conditions, good agreements is obtained when computed results are compared with those obtained by Comsol software, the results have shown that the frequency of the plates increases with the magnetic field and the effect of magnetic field is similar to the Winkler’s foundation.
Hysteresis switching adaptive control of linear multivariable systems

The authors present a model reference adaptive control scheme for deterministic continuous-time multivariable systems represented by square, strictly proper, minimum-phase transfer function matrices. A typical requirement of existing algorithms is to assume that the zero structure at infinity and the high-frequency gain matrix are fully (or at least partially) known. It is well known that these requirements are very restrictive, since in general both the zero structure at infinity and the high-frequency gain matrix depend on plant parameters. It is shown that these restrictive assumptions may be dispensed with by using a hysteresis switching control strategy recently introduced by A.S. Morse et al. (1992). This entails running a finite number of parameter estimators in parallel, and using a switching algorithm to select between candidate estimators based on their associated prediction errors. Hysteresis in the switching algorithm precludes switching arbitrarily rapidly between estimators, and all switching ceases within a finite time. The results represent a significant step forward in understanding the minimal amount of prior knowledge necessary to design a stabilizing controller for a linear multivariable system. <<ETX>>
Identification of Chattonella (Raphidophyceae) species in long-term phytoplankton samples from Santa Giusta Lagoon, Italy

Chattonella species in a Mediterranean lagoon (Santa Giusta Lagoon, Sardinia, Italy) were identified by applying a molecular approach to fixed natural phytoplankton samples collected over the last two decades. Like the other raphidophytes, Chattonella cells are naked and lose their shape when fixed, making species identification difficult on the basis of their morphological characteristics. Employing species-specific primers (oBTG-005-F, oBTG-027-R, oBTG-028-R) for the amplification of the ITS-5.8S rDNA region, we established the occurrence of C. subsalsa in fixed natural phytoplankton samples collected in coincidence with fish death events. Additionally, we established the presence of the recently discovered C. cf. subsalsa Adriatic genotype by analysing cellular cultures obtained from the same lagoon in 2013. This is the second worldwide record of C. cf. subsalsa Adriatic genotype. Our results revealed that the species-specific primers oBTG-005-F and oBTG-028-R distinguished this new genotype only when present singularly. This study provides valuable data that increase knowledge of C. subsalsa genotypes and of the long-term occurrence of Chattonella blooms in a transitional ecosystem through the use of samples up to 20 years old.
Estimating Deoxynivalenol Content of Ground Oats Using VIS-NIR Spectroscopy

ABSTRACT The potential of VIS-NIR spectroscopy as a rapid screening method for resistance of Fusarium-inoculated oats to replace the costly chemical measurements of deoxynivalenol (DON) was investigated. Partial least squares (PLS) regression was conducted on second-derivative spectra (400–2,350 nm) of 166 DON-contaminated samples (0.05–28.1 ppm, mean = 13.06 ppm) with separate calibration and test set samples. The calibration set had 111 samples, and the test set had 55 samples. The best model developed had three PLS components and a root mean square error of prediction (RMSEP) of 3.16 ppm. The residual predictive deviation (RPD) value of the prediction model was 2.63, an acceptable value for the purpose of rough screening. Visual inspection and the VIS spectra of the samples revealed that high-DON samples tended to be darker in color and coarser in texture compared with low-DON samples. The second-derivative spectra showed that low-DON samples tended to have more water and fat content than high-DON samp.
Light Curves and Spectra from a Unimodal Core-collapse Supernova

To assess the effectiveness of optical emission as a probe of spatial asymmetry in core-collapse supernovae (CCSNe), we apply the radiative transfer software SuperNu to a unimodal CCSN model. The SNSPH radiation hydrodynamics software was used to simulate an asymmetric explosion of a 16 zero-age main-sequence binary star. The ejecta has 3.36 with 0.024 of radioactive 56Ni, with unipolar asymmetry along the z-axis. For 96 discrete angular views, we find a ratio between maximum and minimum peak total luminosities of ∼1.36. The brightest light curves emerge from views orthogonal to the z-axis. Multigroup spectra from UV to IR are obtained. We find a shift in wavelength with viewing angle in a near-IR Ca ii emission feature, consistent with Ca being mostly in the unimode. We compare emission from the gray gamma-ray transfer in SuperNu and from the detailed gamma-ray transfer code Maverick. Relative to the optical light curves, the brightness of the gamma-ray emission is more monotonic with respect to viewing angle. UBVRI broadband light curves are also calculated. Parallel with the unimode, the U and B bands have excess luminosity at days post-explosion, due to 56Ni on the unimode. We compare our CCSN model with SN 2002ap, which is thought to have a similar ejecta morphology.
Effect of pH and temperature in production of mycotoxins and antibiotics by phytopathogenic moulds for Persian lime (Citrus latifolia T.) in a complex lime pericarp-base medium

Post-harvest decay of citrus fruits is caused by moulds capable of producing mycotoxins with great impact on health. The objective of this study was to determine the effect of pH and temperature in synthesis of mycotoxins and antibiotics in Persian lime pathogenic and mycotoxigenic moulds, and to investigate the diffusion of mycotoxins inside the citrus fruit. As a result, several mycotoxins were identified, such as aflatoxins and fumonisins. In most of the analysed moulds, synthesis of the secondary metabolites was observed on acidic pH at 20 °C; some antibiotics were found as well. Diffusion of A. niger mycotoxins and antibiotics was observed in the interior of the lime fruit, achieving highest concentration in the septa. Knowing the behaviour of these moulds is useful for evaluation of health risk due to mycotoxins and control of pathogenic and mycotoxigenic post-harvest moulds.
Board of Directors and Ownership Structure: A Study on Small and Medium Enterprises (SMEs) in Malaysia

ABSTRACT Small- and medium-sized enterprises (SMEs) do not gain sufficient economic returns despite their significant economic contributions. A possible cause of poor SME performance is weak corporate governance. However, the corporate governance of SMEs is rarely investigated. Ownership structure provides SMEs with a monitoring mechanism that enhances performance. This study examines the relationships between board characteristics (including size, composition boards, CEO duality, expertise, and ethnicity) and SME performance in Malaysia. This study also explores how such relationships can be moderated by monitoring ownership structure. Survey results on SMEs in Klang Valley and Selangor areas show that non-executive boards and CEO duality are significantly and positively related to firm performance. In comparison, management ownership is significantly and negatively related to performance. Board size, expertise, ethnicity, and family ownership are not significantly related to SME performance. Findings indicate that good corporate governance improves decision making and firm performance. Furthermore, agency theory can explain conflict of interest in SMEs and the importance of corporate governance in enhancing their performance. Keywords: SMEs; corporate governance; CEO duality; ethnicity; managerial ownership; family ownership ABSTRAK Meskipun perusahaan kecil dan sederhana (PKS) menyumbang secara signifikan kepada ekonomi negara, sektor ini tidak memperoleh pulangan ekonomi yang lumayan. Prestasi yang lemah ini berlaku mungkin akibat tadbir urus korporat yang tidak kukuh. Namun, bilangan kajian tadbir urus korporat PKS sangat sedikit. Kajian lepas menunjukkan struktur pemilikan merupakan mekanisma pemantauan yang meningkatkan prestasi PKS. Kajian ini meneliti hubungan ciri lembaga pengarah (termasuk saiz, komposisi ahli, pengarah urusan dualiti, kepakaran dan jenis etnik) dengan prestasi PKS di Malaysia. Kajian ini turut meneroka peranan struktur pemilikan menguatkan hubungan tersebut. Hasil tinjauan PKS di sekitar Lembah Klang dan Selangor menunjukkan ahli lembaga pengarah bukan eksekutif dan pengarah urusan dualiti masing-masing mempengaruhi prestasi syarikat secara positif dan signifikan. Pemilikan pengurusan pula mempengaruhi prestasi syarikat secara negatif dan signifikan. Hubungan yang signifikan tidak wujud antara saiz lembaga pengarah, kepakaran, jenis etnik dan pemilikan keluarga dengan prestasi PKS. Secara keseluruhan, hasil kajian menunjukkan bahawa tadbir urus korporat yang baik meningkatkan proses pembuatan keputusan dan prestasi syarikat. Kajian ini membuktikan bahawa teori agensi adalah relevan untuk menerangkan konflik kepentingan di kalangan PKS dan tadbir urus adalah perlu untuk meningkatkan prestasi.
