The Role of Self-Esteem and Perceived Parental Attitudes in Determining Fear of Negative Evaluation in Men and Women
No full textWOS: 000473207300004The findings in recent literature indicate that fear of negative evaluation is related to many disorders such as body dysmorphic disorder, eating disorders and social anxiety. Therefore, determining the factors that affect the development of fear of negative evaluation seems important for developing preventive programs in the field of mental health. Although previous studies reported that the fear of negative evaluation is related to low self-esteem and rejecting parental attitudes, our knowledge is still inadequate in this area. The aim of this study was to both test the assumption that the attitudes of parents of women and men differ, and to investigate the role of self-esteem and perceived parental attitudes in the determination of the fear of negative evaluation in women and men. To this end, 230 university students (125 of which were women) completed the Rosenberg Self-Esteem Scale, the Perceived Parental Attitudes Scale and the Brief Fear of Negative Evaluation Scale. The results suggest that perceived emotional warmth and rejection scores were different across genders. While women perceived more emotional warmth, men perceived higher rejective parental attitudes. Two different regression analyses were performed to determine the predictors of fear of negative evaluation in women and men. Low self-esteem accounted for 12% of the variance in fear of negative evaluation among women. Overprotective parental attitudes accounted for 20% of the variance in fear of negative evaluation among men. The findings indicate that gender role expectations should be taken into consideration in the investigation of those factors affecting the development of fear of negative evaluation and in the development of preventive interventions. In light of the findings of this study, it is believed that individual interventions which aim to improve self-esteem in women. and education programs which aim to encourage parents to develop positive parental attitudes could be effective as preventive interventions
RIMFRA: Rotation-invariant multi-spectral facial recognition approach by using orthogonal polynomials
No full textÇevik, Nazife (Arel Author)This paper proposes a novel rotation-invariant multi-spectral facial recognition approach (RIMFRA) by using orthogonal polynomials. In the first step, a rotation, illumination and noise invariant local descriptor (RinLd) is proposed to represent the texture patterns of a face image. Color channels of the images embodies non-trivial information about the characteristic of the image. Hence, the local descriptor matrices are extracted among the color channels. The corresponding new descriptor matrices for the red, green and blue channels of the image are extracted. Afterwards, co-occurrence matrices are obtained from the six combinations of the corresponding color channel descriptor matrices, that are red-red, blue-blue, green-green, red-blue, green-blue and red-green. Finally, these matrices are decomposed by using the orthogonal polynomials to achieve a more reliable and characteristic pattern extraction. The coefficients obtained as a result of the decomposition process are used as the ultimate features for the classification of the images. Extensive simulations are conducted over benchmark datasets. As presented by the simulation results, the ultimate features yield very high discriminating performance as well as providing resistance to rotation and illumination variations. © 2019, Springer Science+Business Media, LLC, part of Springer Nature
Fabrication, characterization and fibroblast proliferative activity of electrospun Achillea lycaonica-loaded nanofibrous mats
No full textŞahin, Yeşim Müge (Arel Author)The use of natural compounds such as biocompatible and non-toxic plant extracts, without undesired side effects, in tissue engineering applications, is highly preferred compared to chemical drugs. In this study, the characterization and performance of electrospun Achillea lycaonica-loaded (0.125, 0.250 and 0.500, wt%) poly(lactic acid) (PLA) (8%, w/v) nanofibrous mats for skin tissue engineering were investigated. SEM, FTIR, DSC, and tensile strength test of the electrospun nanofibers have been investigated. Drug releasing test and cell culture study were also carried out. Achillea lycaonica-loaded nanofibrous mats in 0.250 (wt%) and 0.500 (wt%) demonstrated excellent cell compatibility and increased the viability of NIH/3T3 (mouse embryo fibroblast) cells within 72 h. According to the results, Achillea lycaonica-loaded PLA nanofibers have proper tensile strength and controlled release. The working temperature range enlarged for the composites having higher plant extract content. Consequently, Achillea lycaonica-loaded nanofibrous mats have a great potential in skin tissue engineering applications. © 2019 Elsevier LtdDr. Muhammet E.

Inclusions and Noninclusions of Spaces of Multipliers of Some Wiener Amalgam Spaces
No full textThe main purpose of this paper is to study inclusions and noninclusions among the spaces of multipliers of the Wiener amalgam spaces. M. G. Cowling and J. J. F. Fournier in [5], L. Hormander in [22] and G. I. Gaudry in [15], have worked on the space M-G(L-p, L-q), the space of convolution multipliers from L-p into L-q, and studied inclusions and noninclusions among these spaces. In this paper, we consider much larger classes of spaces than L-p and L-q : we consider the Wiener amalgam spaces W(L-p, L-q) and weighted Wiener amalgam spaces W(L-p, L-omega(q)). Firstly, we work on inclusions between the spaces of multipliers of Wiener amalgam spaces. Later by using the Rudin-Shapiro measures, we investigate noninclusions among the spaces of multipliers of Wiener amalgam spaces

Natural Nanohydroxyapatite Synthesis via Ultrasonication from Donax Trunculus Bivalve Sea Shells and Production of its Electrospun Nanobiocomposite
No full text8th International Advances in Applied Physics and Materials Science Congress and Exhibition (APMAS) --APR 24-30, 2018 -- Fethiye, TURKEYWOS: 000481717400064In the present study, hydroxyapatite (HA) and tricalcium phosphate (TCP) bioceramics were prepared via a practical, ultrasonic conversion method from Donax trunculus seashells. These seashells are one of the most common bivalve molluscs of the Mediterranean Sea and can be used as a natural, stable raw material for bioceramic production. Ultrasonication, a powerful method for nano-sized ceramic production, was chosen to synthesize different ceramic phases easily. Raw shells are consisted of calcite and aragonite structures. To synthesize HA and TCP bioceramic materials, first the calcium oxide content of the shells were identified via Differential Thermal Analysis (DTA) and then a calculated amount of phosphoric acid was added drop by drop to obtain the exact stoichiometry. After synthesis, the resultant bioceramics were sintered at 800-850 degrees C for HA and 400-450 degrees C for TCP phases. For bioceramic phases X-ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Field Emission Gun Scanning Electron Microscope (FEGSEM) studies were perform. On the other hand, electrospinning method was used to prepare nanobiocomposites from biocompatible polymeric material as the matrix and the obtained natural bioceramics as reinforcer of the composite system. Three different compositions were used and optimum electrospinning conditions were adjusted to prepare these electrospun structures. Biocomposites were evaluated in terms of structure, mechanic, morphology and biology. The effect of bioceramic content was also discussed. It is revealed that the obtained electrospun nanobiocomposites are good candidates for various tissue engineering purposes due to their enhanced biological and mechanical properties
Observation of psi(3886) -> Xi(1530)(-)(Xi)over-bar(1530)(+) and Xi(1530)(-)(Xi)over-bar(+)
No full textUsing 448.1 x 10(6) psi(3686) events collected with the BESIII detector at BEPCII, we employ a single-baryon tagging technique to make the first observation of psi(3686) -> Xi(1530)(-)(Xi) over bar (1530)(+) and Xi(1530)(-)(Xi) over bar (+) decays with a statistical significance of more than 10 sigma and 5.0 sigma, respectively. The branching fractions are measured to be B(psi(3686) -> Xi(1530)(-)(Xi) over bar (1530)(+)) = (11.45 +/- 0.40 +/- 0.59) x 10(-5) and B(psi(3686) -> Xi(1530)(-)(Xi) over bar (+)) = (0.70 +/- 0.11 +/- 0.04) x 10(-5). The angular distribution parameter for psi(3686) -> Xi(1530)(-)(Xi) over bar (1530)(+) is determined to be alpha = 0.40 +/- 0.24 +/- 0.06, which agrees with the theoretical predictions within 1 sigma. The first uncertainties are statistical, and the second systematic
Big data analytics and models
No full textWhen uncertainty is regarded as a surprise and an event in the minds, it can be said that individuals can change the future view. Market, financial, operational, social, environmental, institutional and humanitarian risks and uncertainties are the inherent realities of the modern world. Life is suffused with randomness and volatility; everything momentous that occurs in the illustrious sweep of history, or in our individual lives, is an outcome of uncertainty. An important implication of such uncertainty is the financial instability engendered to the victims of different sorts of perils. This chapter is intended to explore big data analytics as a comprehensive technique for processing large amounts of data to uncover insights. Several techniques before big data analytics like financial econometrics and optimization models have been used. Therefore, initially these techniques are mentioned. Then, how big data analytics has altered the methods of analysis is mentioned. Lastly, cases promoting big data analytics are mentioned. © 2020, IGI Global
