Determining the Attachment Styles of Football Coaches to Their Athletes

In this study, it was aimed to determine the attachment styles of soccer trainers to their athletes according to various variables. The relationship between the trainers and their athletes is an important element to act in line with the goals, in this context, determining the attachment styles will create an awareness for the trainers and will provide support for the development of the trainers in order to raise successful and mentally healthy athletes in the long term. The research sample consists of 406 licensed male football coaches who are actively performing as trainers in football at different levels and age groups. In the study, a questionnaire was created using the trainer-athlete attachment scale to determine the personal information form attachment styles to collect the demographic characteristics of football coaches. SPSS 25 program was used to analyze the data. It was determined that the data were distributed normally, and the t-test and the One-way ANOVA test was used to compare independent groups. Tukey test was used as a complementary post-hoc analysis to determine the difference after the ANOVA test. The significance level in the analyses was determined to be p <0.05. While there was a significant difference in attachment styles of the trainers according to marital status, number of weekly training and years of coaching; no significant difference was found according to the variables of age, education level and coaching level. As a result, it was found that coaches who are married and train 6 times and more in a week have good problem-solving skills in their interpersonal relationships, have a positive approach to problems, are constructive while solving problems, are self-confident, do not evade responsibility, and have an insistent attitude in solving problems. Trainers can help athletes develop their positive emotions and life satisfaction with healthy evaluations and positive/optimistic thoughts. It is thought that the sharing environment that develops as a result of the cooperation and efforts made in line with common goals in sports environments, especially in training, increases the level of coach-athlete relationship.

Information Privacy Concerns Among Instagram Users: The Case of Indonesian College Students

Background : Teenagers in Indonesia have an open nature and satisfy their desire to exist by uploading photos or videos and writing posts on Instagram. The habit of uploading photos, videos, or writings containing their personal information can be dangerous and potentially cause user privacy problems. Several criminal cases caused by information misuse have occurred in Indonesia. Objective : This paper investigates information privacy concerns among Instagram users in Indonesia, more specifically amongst college students, the largest user group of Instagram in Indonesia. Methods : This study referred to the Internet Users' Information Privacy Concerns (IUIPC) method by collecting data through the distribution of online questionnaires and analyzed the data by using Structural Equation Modelling (SEM). Results : The research finding showed that even though students are mindful of the potential danger of information misuse in Instagram, it does not affect their intention to use Instagram. Other factors that influence Indonesian college students' trust are Instagram's reputation, the number of users who use Instagram, the ease of using Instagram, the skills and knowledge of Indonesian students about Instagram, and the privacy settings that Instagram has. Conclusion : The awareness and concern of Indonesian college students for information privacy will significantly influence the increased risk awareness of information privacy. However, the increase in risk awareness does not directly affect Indonesian college students' behavior to post their private information on Instagram.
Functionalised dextran nanoparticles for drug delivery to the brain

Towards the development of drug carriers that are capable of crossing the Blood Brain Barrier, the techniques of emulsion polymerisation and nanoprecipitation have been utilised to produce nanoparticulate carriers from a systematic series of alkylglyceryl dextrans (of two different average molecular weights, 6 kDa and 100 kDa) that had been functionalised with ethyl and butyl cyanoacrylates. Also, zero length grafting of polylactic acid to butyl, octyl and hexadecylglyceryl dextrans has allowed the preparation of polylactic acid-functionalised nanoparticles. All materials and derived nanoparticles have been characterised by a combination of spectroscopic and analytical techniques. The average size of nanoparticles has been found to be in the range 100-500 nm. Tagging or loading of the nanoparticles with fluorophores or model drugs allowed the preliminary investigation of their capability to act as controlled-release devices. The effects of an esterase on the degradation of one such nanoparticulate carrier have been studied. Testing against bend3 cells revealed that all materials display dose-dependent cytotoxicity profiles, and allowed the selection of nanocarriers that may be potentially useful for further testing as therapeutic delivery vehicles for conditions of the brain.
Finite-time sliding mode control for a 3-DOF fully actuated autonomous surface vehicle

This paper deals with the finite-time trajectory tracking problem for a typical 3-DOF (degree of freedom) autonomous surface vehicle (ASV) subjected to parametric uncertainties and environmental disturbances. Based on the nonsingular terminal sliding mode control (NTSMC) method, several separate classes of robust control inputs are designed to exactly steer all position states of the 3-DOF AVS to the desired paths during alterable finite times. By exploiting the Lyapunov stability theorem and using mathematical analysis, it is proven that all classes of designed robust control inputs are able to fulfill the mentioned finite-time tracking aim. Moreover, three applicable formulas (represented as several nonlinear inequalities) are extracted to determine the required total finite times for the suggested control schemes. Lastly, all designed control methods are numerically tested onto a benchmark 3-DOF AVS called CyberShip II. Provided computer-based numerical simulations (using MATLAB software) depicted the acceptable performance of the proposed control techniques.
Immediate effect of foot reflexology in patients with diabetic neuropathy -Randomized Clinical Trial

Introduction. Diabetic neuropathy (DN) is one of the most frequent chronic complications of type 2 diabetes mellitus (DM2). One technique capable of influencing the central and peripheral nervous system is foot reflexology (FR). Therefore, the objective of this study was to analyze the immediate effect of FR in DN type 2 patients. Method. This was a randomized controlled clinical trial, with 12 participants selected from a list of diabetic patients from the Basic Health Units of the city of Alfenas-MG.

The instruments used were: surface electromyography for analysis of the lateral and medial gastrocnemius muscles, baropodometry to evaluate the balance from the variables of mean pressure and mass division, and the cardiofrequency meter to analyze the relationship between the sympathetic and parasympathetic nervous system and cardiovascular stress. Statistical analysis was used the Shapiro-Wilk test and later the independent t test and Mann Whitney for intergroup comparison. Results. There was only a difference in the EMG of the right lateral gastrocnemius muscle (p=0.04). Conclusion. It was
Understanding social media discontinuance from social cognitive perspective: Evidence from Facebook users

Based on social cognitive theory, this study proposes a research framework to investigate two different social media discontinuance behaviours: reduced usage and abandoned usage. Specifically, perceived technology overload, information overload and social overload are the environmental factors that induce negative personal states, including dissatisfaction and social media fatigue, which lead to negative behavioural changes, such as reduced usage and abandoned usage of social media. The proposed research model was tested empirically with data collected among Facebook users. The research results indicate that impacts from perceived technology overload, information overload and social overload on social network fatigue and dissatisfaction vary. Dissatisfaction exerts greater impacts on abandoned-usage behaviour than social media fatigue, but similar impacts on reduced-usage behaviour as social media fatigue. In addition, reduced-usage behaviour was found to lead to abandoned-usage behaviour. Finally, we discuss the theoretical and practical contributions that can be gleaned from the proposed research model.
Dynamic Aggregation Modeling of Grid-Connected Inverters Using Hamilton's-Action-Based Coherent Equivalence

The high penetration of renewable energy generation (REG) systems influences the dynamics of power systems. Accurate transient simulations and dynamic models are indispensable for the research on the dynamic behavior of REG systems. A large-scale REG system consisting of numerous grid-connected inverters consumes a large amount of computation time, so a dynamic aggregated model is needed for efficient simulation. The aggregated model established by coherent equivalence fits the detailed model well, and thus it is widely used in the aggregation of large-scale dynamic systems. Presently, the key challenge of the application of the coherent-equivalence method is to identify inverters that have similar dynamic characteristics. The Hamilton principle expressed by Hamilton's action has a simple form and indicates the comprehensive dynamic characteristics of inverters. Thus, this paper proposes a coherent-equivalence method of inverters based on Hamilton's action. The proposed method is applied to a wind farm of 16 permanent magnet synchronous generator-based wind turbines for demonstration. Compared with the existing equivalence method without considering coherency, the proposed method shows advantages in effectiveness and accuracy.
Floral Biology and Pollination Efficiency in Yam (Dioscorea spp.)

Yam (Dioscorea spp.) is a monocotyledonous herbaceous vine cultivated for its starchy underground or aerial tubers in the tropics and subtropics. It is an allogamous and polyploid species that reproduces by both sexual and asexual mechanisms. However, many of the landrace cultivars, including most of the popular varieties, reproduce exclusively by vegetative propagation (planting the tubers). These varieties are either sterile or produce sparse and irregular flowering with high flower abortion rate, low fruit and seed set. Production of crossbreed seeds for genetic improvement and for maintaining genetic diversity in yams is, therefore, mainly achieved through natural or managed pollination. Flowering in yam is mostly dioecious and, in some instances, monoecious. Flowering asynchrony, sticky nature of the pollen grains, and cross incompatibility are among the challenges in making genetic progress in yam breeding. There are many limitations in basic and applied knowledge of yam flower biology and pollination. This paper, therefore, reviews the flowering biology, pollination, and methods of improving pollination efficiency in yam breeding programs.
On Scalable Multiobjective Test Problems With Hardly Dominated Boundaries

The DTLZ1–DTLZ4 problems are by far one of the most commonly used test problems in the validation and comparison of multiobjective optimization evolutionary algorithms (MOEAs). However, very recently, it has been pointed out that they have the following two special characteristics: 1) the regularly oriented Pareto front shape and 2) the single distance function. As a modification of them, this paper presents a new set of test problems mDTLZ1–mDTLZ4 to avoid the two special characteristics. Using these new test problems, we investigate the performance of three representative multiobjective evolutionary algorithms NSGA-II, MOEA/D-Tch, and SMS-EMOA. Experimental results indicate that the performance of NSGA-II and MOEA/D-Tch deteriorates on mDTLZ1–mDTLZ4. Subsequently, our analysis reveals that there exist the hardly dominated boundaries in each of mDTLZ1–mDTLZ4, which hinder the approximation of Pareto dominance-based algorithms and Tchebycheff-decomposition-based algorithms. Furthermore, we summarize that the hardly dominated boundary should be an often encountered problem feature in multiobjective optimization. Last but not least, we point out and validate some coping strategies for dominance-based algorithms and decomposition-based algorithms to overcome the challenges caused by the hardly dominated boundary.

STUDY OF SOYBEAN AND OF RICE BRAN OIL BEHAVIOUR REUSED IN POTATO DESCONTINUOS FRYING PROCESS

This study had as objective evaluate quality parameters of rice bran and soybean oils after successive fries. Twelve lots of 200 g of potato cut type toothpick were taken to the frying into two different oil types, rice bran and soybean. The applied analytical methods for evaluation of the alteration in the oils included free fatty acid and peroxide index determinations, before and after the frying process. After predeterminated frying periods, the sensory evaluation of the oil samples were performed for color and odor attributes, and sensory evaluation of the fried potatoes for color, odor and flavor attributes. The rice bran oil presented higher stability, and it affected less the potato characteristics during the successive frying processes. The soybean oil presented significant color and odor sensory alterations, starting from the fourth frying period, and the rice bran oil starting from the eighth period. The potatoes presented sensory alterations of color, odor and flavor, in soybean oils used by the eighth frying period, while they just presented alterations in rice bran oils used above the twelfth time.
Reverse time migration (RTM) imaging of iron-oxide deposits in the
Ludvika mining area, Sweden

Abstract. To discover or delineate mineral deposits and other geological features such as faults and lithological boundaries in their host rocks, seismic methods are a qualified choice, given their resolution power at depth. One major goal for seismic methods is to produce a reliable image of the subsurface given the typical discontinuous geology in crystalline environment with low signal-to-noise ratio. In this study, we investigate the usefulness of reverse time migration (RTM) imaging algorithm in hardrock environment by applying it to a legacy 2D dataset, which was acquired in the Ludvika mining area of central Sweden. We provide a how-to solution for applications of RTM in future and similar datasets. When using the RTM imaging technique properly, it is possible to obtain high-fidelity seismic images of the subsurface. Due to good amplitude preservation in the RTM image, the imaged reflectors provide indications to infer their geological origin. Aside from the chosen seismic imaging algorithm, we illustrate that two other important factors for successful RTM imaging workflows are the suitable acquisition and careful data pre-processing. Exemplified with the Ludvika legacy data, the RTM method allows imaging the iron-oxide deposits at a great level of detail down to 1200 m depth as shown from previous studies. It also provides much-improved images of the lithological contacts and crosscutting features relative to the mineralized sheets. Some of the imaged crosscutting features are considered to be crucial when interpreting large-scale geological structures of the site and the likely disappearance of mineralization at depth. The RTM imaging workflows have the potential to be used on hardrock seismic data and for deep targeting mineral deposits, a key message we would like to deliver in this article.
Investigation on existing states and photoluminescence property of silver in the SiO2 three-dimensionally ordered macroporous materials

The photoluminescence properties of silver species, including Ag+, Ag+–Ag+, Ag0, and Ag nanoparticles in various matrices, such as gel and glass have been extensively reported. In the present study, we present the preparation of silver including SiO2 three-dimensionally ordered macroporous (3DOM) materials and investigate the existing states and photoluminescence property of silver in the SiO2 3DOM materials. The results show that only Ag+ ions exist in the SiO2 3DOM materials sintered at temperature below 400 °C. With the increasing sintering temperature, the Ag+ ions gradually transform into Ag+–Ag+, where simultaneously, a part of Ag+–Ag+ transform into Ag nanoparticles. The Ag+–Ag+ and Ag nanoparticles are formed in the SiO2 3DOM materials sintered at temperature from 450 to 650 °C. Finally, only Ag nanoparticles occur in the SiO2 3DOM materials prepared at 750 °C. The formation mechanisms of Ag species were discussed in the SiO2 3DOM materials.
