Characteristics of Korean Secondary Female PE Teachers’ Voluntary Professional Development

The purpose of this study was to investigate the characteristics of Korean female secondary PE teachers’ voluntary professional development(PD) activity participation in relation to female PE teachers’ perceived professional identity. Data were collected from online questionnaires (n=107) and in-depth interviews (n=15) with female secondary PE teachers. Findings revealed that female PE teachers’ voluntary professional development activities were characterized as: (a) prevalence in sport skill development activities in order to overcome relatively a low level of sport skills than that of male PE teachers, (b) dominance of self-directed learning activities with the Internet search or reading, and (c) seeking ideal mix of theory and practice by participating in teacher learning communities. Female PE teachers’ voluntary PD participation was related to their notion of PE subject as sport skills-centered subject, relatively weak professional identity due to lack of sport skills compared with male teachers, and perceiving teacher learning community as a viable learning context to support their everyday pedagogical PE practice.

Comparing analysis of guided modes excitation by fundamental mode injecting through the USF, DSF, and NZDSF fibers coupled to conventional multimode fiber

Comparing analysis of guided mode excitation by fundamental mode injecting through the different types of singlemode fibers, coupled to conventional multimode fiber, is proposed. Multimode fiber excitation by singlemode laser source is represented in the form of splice of singlemode and multimode fibers. Mode power redistribution, depended on fiber type, fiber parameters and launch conditions, was researched. Following types of singlemode fibers were considered: usual step index fibers (USFs), dispersion shifted fibers (DSFs) and non-zero dispersion shifted fibers (NZDSFs). The overlap integrals method for calculating mode coupling coefficients at the splice of two optical fibers with mismatched parameters is applied. Modified Gaussian approximation for determination of waveguide parameters of spliced fibers with arbitrary index profile is used. Results of mode coupling parameters calculations at splice of mentioned types singlemode fibers and conventional multimode fibers are represented.
HIFiRE: an international collaboration to advance the science and technology of hypersonic flight

The Hypersonic International Flight Research and Experimentation (HIFiRE) program was created to perform hypersonic flight tests intended to quickly and affordably gather fundamental scientific data that are difficult or impossible to obtain via ground testing alone. The program is being executed jointly by the United States Air Force Research Laboratory (AFRL) and the Australian Defence Science and Technology Organisation (DSTO), with significant support from partners Boeing in the U.S. and the University of Queensland in Australia. Intellectual, financial, and physical resources from the four partners have been combined to achieve these essential objectives with the overarching goal of advancing the art and science of hypersonic flight.
On the Application of Numerical Methods for the Calculation of the External Aerodynamics of a Streamlined Car Body

The present paper describes the application of a numerical tool for the evaluation of the aerodynamic performance of a streamlined car shape. The numerical simulations are carried out using a commercial code based on an unstructured grid layout. Tests are made using the k-ε turbulence model and the Shear Stress Transport model. The influence of the advection scheme is also studied. The experimental measurements are made on a Gottingen-type wind tunnel with a test section of 2x2x8 m. Computations are compared with experimental values for the surface pressure distribution and measured forces.
An Empirical Study of the Effect of Online Comments on Consumer Buying Behavior

There are many factors that affect the buying decision of consumers, and online comments are very important among these factors. Online comments made by customers or users have a direct impact on buying decisions. For this reason, consumers carefully examine online comments from other customers or users to access more accurate and realistic information during the buying decision process. The aim of the study, which is built on this understanding, is to examine the effects of online comments on consumer buying behavior. For this purpose, the study was carried out at Selcuk University with a random sampling method using a google survey. A total of 400 people at the university were reached. In this way, the opinions of different segments including academics, university staff and students were asked. SPSS 22.0 program was used in the analysis of the collected data. Pearson correlation and multiple regression analyzes were used because the scale used in the study was a normal distribution and parametric tests were used. As a result, it was observed that as the positive perspective of the participants on consumer comments increased, buying behavior also increased. However, no significant relationship was found between attitude towards comment and buying behavior (p>0.05). The fact that the study was carried out at a university and that it covers the entire university, from academicians to students, distinguishes the study from others and makes it significant. Future studies on this subject can be carried out on other segments of society.
Survival, morphological variability, and performance of Opuntia ficus-indica in a semi-arid region of India

ABSTRACT Cactus pear (Opuntia ficus-indica (L.) Mill. ) can survive extreme environmental condition and is known for its fodder potential in many parts of the world. The morphological diversity of 15 introduced accessions was evaluated at Jhansi, Uttar Pradesh, India. The plants were established in 2013. Survival and nutrient status were evaluated after two years. Above-ground plant height, biomass, primary and secondary cladode numbers, primary and secondary cladode lengths and below-ground root length, weight, and surface area measurements were done six years after cladode planting. Yellow San Cono, White Roccapalumba, and Seedless Roccapalumba survived 100%. The discriminant traits according to principal component analysis were: primary cladodes plant−1 (component loading, 0.87), primary cladodes biomass (0.95), secondary cladodes plant−1 (0.83), canopy width (0.84), and plant biomass (0.92). Hierarchical cluster analysis grouped 15 accessions into two main clusters based on 17 morphological traits. Cluster I showed favorable values for many above- and below-ground morphological traits while Cluster II showed higher performance for root system width, height, and biomass, and primary and secondary cladode numbers. The results indicate that cactus pear accessions have considerable morphological variability and genetic diversity suitable for promotion as alternative fodder resources in semi-arid regions of India.
Exploring the link between Parkinson’s disease and Diabetes Mellitus in Drosophila

Parkinson’s disease (PD) is the second most common neurodegenerative disease. Diabetes mellitus (DM) is a metabolic disease characterized by high levels of glucose in blood. Recent epidemiological studies are highlighting the link between both diseases; it is even considered that DM might be a risk factor for PD. To further investigate the likely relation of these diseases, we have used a Drosophila PD model based on inactivation of the DJ-1β gene (ortholog of human DJ-1), and diet-induced Drosophila and mouse T2DM models, together with human neuron-like cells. T2DM models were obtained by feeding flies with a high sugar containing medium, and mice with a high fat diet. Our results showed that both fly models exhibit common phenotypes such as alterations in carbohydrate homeostasis, mitochondrial dysfunction or motor defects, among others. In addition, we demonstrated that T2DM might be a risk factor of developing PD since our diet-induced fly and mouse T2DM models present DA neurodegeneration, a hallmark of PD. We have also confirmed that neurodegeneration is caused by increased glucose levels, which has detrimental effects in human neuron-like cells by triggering apoptosis and leading to cell death. Besides, the observed phenotypes were exacerbated in DJ-1β mutants cultured in the high sugared medium, indicating that DJ-1 might have a role in carbohydrate homeostasis. Finally, we have confirmed that metformin, an antidiabetic drug, is a potential candidate for PD treatment and that it could prevent PD onset in T2DM model flies. This result supports antidiabetic drugs as promising PD therapeutics.
Reduce, reuse, recycle? An examination of factors influencing environmental behavior in Denver, Colorado

Non-recycling and non-composting of municipal solid waste have important natural resource management implications, in that they both reduce energy, water, and raw natural resource use. Responsible waste management also likely has positive climate impacts by virtue of reducing greenhouse gas emissions. Recycling and composting are pro-environmental behaviors that have been shown to be influenced by numerous sociodemographic and psychological factors. This study analyzes the correlation of a number of variables with frequency of recycling and composting in select census tracts in Denver, CO, USA, with the goals of informing waste management policy and contributing to the overall pro-environmental behavior literature. The results show that habit strength as quantified by the Self-Reported Habit Index has the strongest correlation with both recycling and composting behavior. Overall, waste management policy should focus on influencing habit formation, using literature to dissuade residents from placing plastic bags into recycling bins, and consider charging a minimal fee for recycling.
Regulation of Hedgehog Signaling Through Arih2-Mediated Smoothened Ubiquitination and Endoplasmic Reticulum-Associated Degradation

During Hedgehog signaling, the ciliary levels of Ptch1 and Smo are regulated by pathway activity. At the basal state, Ptch1 localizes to cilia and prevents the ciliary accumulation and activation of Smo. Upon stimulation with Hedgehog ligand, Ptch1 exits cilia and relieves the inhibition of Smo. Uninhibited Smo concentrates in cilia, becomes activated, and activates the downstream steps of the pathway. Loss of the ubiquitin E3 ligase Arih2 elevates the cellular level of Smo, causes Smo to inappropriately localize to cilia at the at the basal state, and elevates basal expression of Hedgehog responsive genes. Mice express two isoforms of Arih2 with different N-termini, but neither isoform localizes to cilia. Instead, Arih2α is found in the nucleus and Arih2β is found on the cytoplasmic face of the endoplasmic reticulum. Re-expression of endoplasmic reticulum-localized Arih2β, but not nuclear-localized Arih2α returns the cellular Smo levels back to normal and rescues the ciliary Smo accumulation phenotype. When Arih2β is missing, protein aggregates accumulate in the endoplasmic reticulum and the unfolded protein response is activated. Inhibitor studies suggest that Arih2β functions to mark excess or misfolded Smo for degradation by endoplasmic reticulum-associated degradation. When Arih2β is defective, excess Smo, possibly misfolded, is delivered to the cell surface and cilium where it interferes with pathway regulation. These findings add another level of complexity to the Hedgehog pathway.
Modeling suffusion of ideally gap‐graded soil

A novel framework for describing suffusion in cohesionless soil, incorporating ideally gap‐graded soil, is presented in this paper. The key assumption of the proposed simulation is that an erodible particle flow is induced primarily by drag force. The multiphase flow simulation for seepage‐soil particle flow phenomena is conducted based on the proposed framework. The validity of the proposed method is checked through a simulation of past laboratory experiments, in which the variation in grain size distributions is grasped by a sieve analysis. The primary results show cumulative fines loss; therefore, a comparison of the cumulative fines loss is mainly discussed in this research. In addition, a discussion is given on the two different parameters affecting the erosion behavior, namely the p−value$p - value$ in the tortuosity function, T(∅)$T( \emptyset )$ , and the clogging relaxation time, βclog${{{\beta}}_{clog}}$ . The tortuosity is the ratio of the actual flow path and the distance between its ends, while clogging relaxation time is the parameter that considers the particle flow through the bottleneck. The results show that the numerical simulation provides a good correlation with the experiment, while the p−value$p - value$ is 3 which is the highest value for a geo‐material. Moreover, the simulation results of the cumulative fines loss for each particle size also confirm that smaller particles will be fully eroded earlier than larger ones, and that larger particles will slowly become detached from the soil mass.
A Neuro-fuzzy Logic Model Application for Predicting the Result of a Football Match

Many various models have been proposed with the goal of estimating the factors that determine the winner and losers in a football match, and many other models have been proposed with the goal of estimating the elements that determine the winner and losers in a football match. Predicting the result of a football match has been the interest of many gamblers and football fans all over the world. In this research, a Neuro-fuzzy logic model for forecasting the outcome of a football match is proposed. The suggested model comprises two phases: the first utilizes a neural network model to generate the primary factors that impact team performance; the second phase uses a neural network model to generate the major factors that affect team performance. In the second phase, a fuzzy logic model is used to forecast the outcome of a football match. MatLab 2008 was used to simulate the proposed system. In order to forecast the winner and loser of each football match, the model took into account a variety of parameters that affect both the host team and the visiting squad. The results show that the Neurofuzzy logic technique is an effective tool for forecasting the outcome of a football match.
Grounded theory

ABSTRACT The purposes of this paper were to (a) describe and assess the use of grounded theory methodology (GTM) in sport psychology over the past 11 years and (b) provide some guidance for best practices moving forward. Following a brief summary of the history of GTM, we present the results of a rapid review of seven sport psychology journals from 2009 to 2021. A total of 35 articles that made claims regarding the use of GTM as a methodology were retained. The retained articles were assessed using 11 criteria. Overall, the methodological completeness of GTM studies in sport psychology appears to have improved over the past decade. Twenty-two of the 35 articles met all, or all but one, of the criteria. Thirteen articles did not meet two or more of the criteria. In terms of areas for improvement, the least widely reported procedures were theoretical sampling (reported in 22 of 35 studies), theoretical saturation (22 of 35 studies), and assessment of theory (22 of 35 studies). Furthermore, the sophisticated positioning of theoretical sensitivity was sometimes lacking in the articles. We discuss ways in which researchers can increase the conceptual and theoretical sophistication of methodologically sound GTM studies.
Associative Word Relations in Natural Language Processing

ABSTRACT Motivation for this work comes from the longest-running Serbian television quiz show called TV Slagalica and more specifically from one of its games named associations. In the associations game, two players attempt to guess a solution given several clue words. There is a large number of publicly available game scenarios that were used to evaluate applicability of trained artificial neural networks to predict possible solutions. Material used for the network training was obtained through unconventional sources as no professional text corpus exists for Serbian language. Under outlined schemes, it is observed that solution words come up within 2% or less of the training vocabulary, depending on the method of data preparation. Data preparation and neural network training specifics are further outlined to demonstrate effects of each technique used. Even though the results obtained are below human-level performance, they can nevertheless be useful for puzzle creation.
A high-accuracy and high-efficiency digital volume correlation method to characterize in-vivo optic nerve head biomechanics from optical coherence tomography

In-vivo optic nerve head (ONH) biomechanics characterization is emerging as a promising way to study eye physiology and pathology. We propose a high-accuracy and high-efficiency digital volume correlation (DVC) method for the purpose of characterizing the in-vivo ONH deformation from volumes acquired by optical coherence tomography (OCT). Using a combination of synthetic tests and analysis of OCTs from monkey ONHs subjected to acute and chronically elevated intraocular pressure, we demonstrate that our proposed methodology overcomes several challenges for conventional DVC methods. First, it accounts for large ONH rigid body motion in the OCT volumes which could otherwise lead to analysis failure; second, sub-voxel-accuracy displacement can be guaranteed despite high noise and low image contrast of some OCT volumes; third, computational efficiency is greatly improved, such that the memory consumption of our method is substantially lower than with conventional methods; fourth, we introduce a parameter measuring displacements confidence. Test of image noise effects showed that the proposed DVC method had displacement errors smaller than 0.028 voxels with speckle noise and smaller than 0.037 voxels with Gaussian noise; The absolute (relative) strain errors in the three directions were lower than 0.0018 (4%) with speckle noise and than 0.0045 (8%) with Gaussian noise. Compared with conventional DVC methods, the proposed DVC method had substantially improved overall displacement and strain errors under large body motions (lower by up to 70%), with 75% lower computation times, while saving about 30% memory. The study thus demonstrates the potential of the proposed technique to investigate ONH biomechanics.
On the appification of dictionaries:: from a Chinese perspective

The advent of the Internet and the rapid development of computer technology have brought great changes into the dictionary-making scene worldwide. Such changes are evident not only in dictionary-making processes but also in the way dictionaries are presented to their target users. In recent years, as the number of mobile users increases, the use of dictionary apps has experienced a sharp rise. This paper attempts to make a tentative study of currently available dictionary apps, with an emphasis on English-Chinese dictionary apps. In order to present a panoramic view of the appification scene, this paper will first briefly discuss the major English dictionary apps that are popular with mobile users worldwide, then survey the bilingual dictionary apps; subsequently, the pros and cons of appified dictionaries will be examined in depth. Finally, the paper will also touch upon the influences of the use of dictionary apps on dictionary-making.
Tolerance of 16-Channel Dense Wavelength Division Multiplexing System to Fibre Dispersion and Four-Wave Mixing under Varying Capacities and Channel Spacing

An essential feature of a long-haul Optical Communication System (OCS) is to transmit huge volumes of data over long distances. In OCS, fiber dispersion and Four-Wave Mixing (FWM) play negative roles in achieving this, as the propagation of the light signal, associated with the pulse, travels at varying speeds. Dense Wavelength Division Multiplexing (DWDM) system is not spared from these identified limitations. In this work, a mathematical analysis for the dispersion and FWM was presented and validated through simulation software. The research was designed and implemented using an optical simulation software tool, OptiSystem 17.0. Transmission parameters of dispersion and Nonlinear (NL) effects due to refractive index, FWM, were considered. The research was carried out on a 125 km-long fiber link and was investigated under a 16-channel DWDM system. The effects of identified limitations on the performance of the DWDM system with channel arrangement of 100, 50, and 25 GHz were further explored. This work compared the DWDM system under these different channel arrangements. The transmission performance of the DWDM system was evaluated based on signal power, noise power, and eye pattern. The results obtained show that any increase in capacity causes significant decreases in the performance of the DWDM system. It was, however, noted that noise power is independent of an increase in bit rate. The results obtained further revealled that the launched power of the system must be reduced for better performance of the DWDM system and improved immunity against identified limitations.
