Predictors of Contraceptive Self-Efficacy and Condom Use Among Young Black Women Who Have Sex With Women and Men

Abstract Black women who have sex with women and men (BWSWM) are at risk for unplanned pregnancies, human immunodeficiency virus (HIV), and other sexually transmitted infections (STIs). However, there is a paucity of studies assessing psychosocial factors related to sexual risk in this population. This study investigated the relationship among condom use; contraceptive self-efficacy; lesbian, gay, and bisexual (LGB) identity; sexuality-religious conflict; parent support for participants’ attraction to women; and LGB community support within a sample of 162 participants who responded to an online survey. Participants were cisgender women (n = 152) and genderqueer or gender-nonbinary participants who were assigned female at birth (n = 10) aged 18 to 35. Hierarchical linear regression analyses indicated that LGB identity, low sexuality-religious conflict, and greater parent support predicted contraceptive self-efficacy and, in turn, greater contraceptive self-efficacy mediated the relationship between these factors and increased condom use. Implications for work with this population in research and clinical contexts are considered.
Opposite effects of returnee and non-local independent directors on firm’s environmental disclosure and performance

ABSTRACT Government programmes and policies in China have brought energy conservation and emission reduction issues into focus. Given the positive role of independent directors and media in corporate governance, the study explores the impact of independent director’s characteristics and media exposure on firm’s environmental disclosure and performance. We find that independent director’s overseas background is positively associated with environmental behaviour, whereas non-local independent director is negatively related to environmental behaviour. The split-sample analyses further support that media coverage plays a positive role both through itself directly and via its impact on independent directors. In supplementary analyses, media exposure has a more significant effect on state-owned than on non-state-owned enterprises. Additionally, non-independent director’s overseas experience also improves firm’s environmental behaviour. The findings enable us to identify a specific channel to improve environmental disclosure and corporate governance, which is through the impact of media on certain independent directors such as returnee-independent directors in state-owned enterprises.
Influence Of Microfinance On Economic Empowerment Of Women

Women have competencies of changing the society along with the world. In developing countries, women are facing evil of gender discrimination. Men and women are not equally privileged but scenario is changing now because females are being empowered but still women are suffering from gender inequality problem. Women empowerment is need of hour for development of the world. The government took initiative in form of microfinance to carry forward women in life. So, it becomes necessary to analyse influence of microfinance on women empowerment. It is based on descriptive research design with using multistage sampling technique. The sample size is 400 rural women beneficiaries of Haryana and information is collected by pre-designed questionnaire through interview Data is conducted through SPSS. Regression and correlation analysis is used to examine data through SPSS. Microfinance measured through micro-credit and micro saving. Economic empowerment selected indicators are household income and household saving. The researchers found that there is positive impact of microfinance on economic empowerment of women. This study will be fruitful for the government, microfinance institutions and banks in policies making to empower women. This study could encourage women for savings and investing activities. It might inspire women to take part in microfinance schemes
Laser-induced nuclear dynamics in hydrocarbons

Hydrocarbon molecules play an important role in various situations in our daily life ranging from sugar, fat, and protein in food consumption to isopropanol for cleaning of glasses. While most of these hydrocarbons exist naturally, others have to be produced by special processes involving bond rearrangements, which result in an altered molecular structure and thus in changed chemical, physical, and biological properties. Apart from standard chemical procedures another promising possibility to control such molecular rearrangements is based on ultrashort laser pulses with defined electric fields, so called carrierenvelope phase (CEP) stable laser pulses. In this thesis, the fundamental processes involved in the interaction of ultrashort laser pulses with small hydrocarbons, i.e. acetylene and propadiene, are investigated. Especially the bond rearrangement via proton migration, also called isomerization, is controlled via the CEP or the applied laser intensity. In the first part of this thesis, the CEP control over isomerization is explained by a superposition of vibrational wave-packets, which are triggered by the laser pulse. The initial directionality of the wave-packet predetermines the final molecular structure, which manifests long after the laser pulse has passed. Investigating both the intensityand the CEP-dependence of the isomerization reveals the influence of the ionization onto subsequent nuclear motion. For low intensities (below 1.5 · 10 W/cm), the non-sequential double-ionization allows for a strong CEP-control of the isomerization. By increasing the intensity, sequential double-ionization becomes the dominating process, such that the CEP-control is suppressed. In order to investigate the temporal evolution of the isomerization, a few-cycle pumpprobe experiment is performed on acetylene. The typical pulse duration of below 5 fs is faster than any nuclear motion and hence permits the detection of different molecular reactions triggered by the ultrashort laser pulse. First, the isomerization process is visualized in “real” time, enabling us to determine the mean isomerization time to 54 fs. Secondly, a vibrational motion of 26 fs is detected, indicating CC-bond vibrations in the cation state. Thirdly, the duration of a vibrational motion is determined for CHand CC-bond vibrations in the dication state to be 11 fs and 20 fs, respectively. Furthermore, in dissociating molecules, the effect of enhanced ionization (EI) is investigated in acetylene. EI is characterized by a significant enhancement of the ionization probability for molecules with a distinct internuclear distance, i.e. 1.4 Å for the CC-bond and 2.0 Å for the CH-bonds. Experimentally, this effect was observed as an increased ionization yield between 10-40 fs.
The effectiveness of an online intervention in stimulating injury-preventive behaviour in adult novice runners: Results of a randomised controlled trial

Background The online intervention Runfitcheck was developed to stimulate injury-preventive behaviour among adult novice runners. Objectives This study evaluated the effectiveness of Runfitcheck on injury-preventive behaviour among adult novice runners. Methods A randomised controlled trial was conducted among adult novice runners. The intervention group had access to the Runfitcheck intervention, the control group performed their running activities as usual. One, three, and five months after enrolment, participants reported retrospectively what they had done regarding injury-preventive behaviour (operationalised as (i) using a (personalised) training schedule; (ii) performing strength and technique exercises; and (iii) performing a warm-up routine prior to running). Relative Risks (RR) and 95% Confidence Interval (95%CI) were used to analyse behavioural change. Results The intervention group (n=715) searched more often for information about a warm-up routine (RR 1.211; 95%CI 1.080–1.357), and added more often strength exercises to their warm-up routine (RR 1.228; 95%CI 1.092–1.380). The intervention group performed more often running technique exercises compared to the control group (n=696) (RR 1.134; 95%CI 1.015–1.267), but less often strength exercises (RR 0.865 (95%CI 0.752–0.995). Within the group of runners that did not perform any warm-up routine at enrolment (n=272), the intervention group started to perform a regular warm-up routine more often than the control group (RR 1.461; 95%CI 1.084–1.968). No significant results were found for using a training schedule. Conclusion The online intervention Runfitcheck was effective in stimulating aspects of injury-preventive behaviour in adult novice runners, mostly related to a warm-up routine.

Procrastination of university students in the context of academic motivation and self-control

Objectives. Procrastination is a phenomenon, that causes negative consequences in terms of achieving study and work goals, especially for teachers and students of teacher courses. The aim of the research was to examine the contribution of self-control and academic motivation on procrastination, and to examine the differences in procrastination with respect to socio-demographic factors.Sample and setting. 333 university students from teachers’ courses of the Presov University (68.5% of women; Mage=20.51, SD=1.61) participated in the research. The respondents completed questionnaires that measured procrastination, socio-demographic variables (gender, age, year of study, living during the semester), self-control, and academic motivation (intristic motivation to know, intristic motivation toward accomplishment, intristic motivation to experience stimulation, external regulation, introjected regulation, identified regulation, amotivation). Statistical analysis. Data were analysed by descriptive statistics, t-tests, and linear regression.Results. The results show no age and gender differences in the procrastination. The linear model explained 45,8% of the variation in the procrastination. Four variables were significant: self-control, introjected regulation, gender, and living in a sublet. The results confirm an association between self-regulatory mechanisms, motivation, and autonomy of university students. The results also have shown the importance of these variables within the reduction of procrastination among future teachers.Study limitation. Unbalanced sample distribution in terms of study years; cross-sectional and self-reported data.
Transepithelial potential difference governs epithelial homeostasis by electromechanics

Studies of electric effects in biological systems, from the work on action potential to studies on limb regeneration or wound healing, commonly focus on transitory behaviour and not on addressing the question of homeostasis. Here we use a microfluidic device to study how the homeostasis of confluent epithelial tissues is modified when a transepithelial potential difference that is different from the natural one is imposed on an epithelial layer. When the field direction matches the natural one, we can restore perfect confluence in an epithelial layer turned defective either by E-cadherin knockout or by weakening the cell–substrate adhesion; additionally, the tissue pushes on the substrate with kilopascal stress, inducing active-cell response such as death and differentiation. When the field is opposite, the tissue pulls with similar strengths, whereas homeostasis is destroyed by the perturbation of junctional actin and cell shapes, increased cell division rate and formation of mounds. Most of these observations can be quantitatively explained by an electrohydrodynamic theory involving local cytoplasmic electro-osmotic flows. We expect this work to motivate further studies on the long-time effects of electromechanical pathways with important tissue engineering applications. Epithelial tissues such as those in the gut or skin are strongly polar, generating electric fields that play a role in wound healing and nutrient transport. Changing the field direction in a layer of tissue disrupts its homeostatic stability.
System for Neural Network Determination of Atrial Fibrillation on ECG Signals with Wavelet-Based Preprocessing

Today, cardiovascular disease is the leading cause of death in developed countries. The most common arrhythmia is atrial fibrillation, which increases the risk of ischemic stroke. An electrocardiogram is one of the best methods for diagnosing cardiac arrhythmias. Often, the signals of the electrocardiogram are distorted by noises of varying nature. In this paper, we propose a neural network classification system for electrocardiogram signals based on the Long Short-Term Memory neural network architecture with a preprocessing stage. Signal preprocessing was carried out using a symlet wavelet filter with further application of the instantaneous frequency and spectral entropy functions. For the experimental part of the article, electrocardiogram signals were selected from the open database PhysioNet Computing in Cardiology Challenge 2017 (CinC Challenge). The simulation was carried out using the MatLab 2020b software package for solving technical calculations. The best simulation result was obtained using a symlet with five coefficients and made it possible to achieve an accuracy of 87.5% in recognizing electrocardiogram signals.

Role of Flash Glucose Monitoring System in Diabetic Patients with Chronic Liver Disease

Background: Diabetic patients show serious complications of chronic liver disease. The monitoring of glucose in diabetic patients with chronic liver disease is very challenging. Generally, the glycaemic control monitoring in chronic liver disease patients is the same as in a person who does not have any liver disease. Flash glucose monitoring system is a way to measure glucose levels of body without pricking the body. It is an innovative method of measuring glucose levels. A flash glucose monitor is a small sensor. This sensor is a small sticky chip and is attached on the skin of the arm. One side of the chip has a small needle that goes inside the skin. It records glucose levels throughout day and night continuously. Levels of glucose can be assessed whenever wanted. Materials and Methods: The study was conducted in the Medical Ward 1, Bahawal Victoria Hospital, Bahawalpur and the Department of Pathology, Quaid-e-Azam Medical College, Bahawalpur from 1st January 2018 to June 2020. Freestyle Libre Sensor flash glucose monitoring system (by CoolPlus Medical) was used to measure glucose of subcutaneous interstitial fluid. The disposable sensor was applied to the back of the arm for up to 14 days. Sensor is calibrated by the factory with no automatic alarms. Results: We noticed that the results of the patients who had co-existing disease of chronic hepatitis and diabetes mellitus had same results of glucose readings when measured by flash glucose monitoring system and by finger prick for glucose measurement by glucometer. Conclusion: Flash glucose monitoring system is way better than self monitoring blood glucose method by glucometer in diabetic patients with chronic liver disease.

Fuzzy clustering for TV program classification

In order to achieve TV program group recommendation, an approach based on fuzzy clustering is proposed for program classification. We first describe the XML based program description metadata representation, in which both textual and symbolic information is included. Secondly it presents the program feature extraction and presentation method. A program is defined as two vectors, one is based on term statistics implying what the program is about, and the other reflects broadcasting characteristics of the program. Then the classifying approach based on fuzzy clustering is proposed. The approach goes: normalizing original data, building fuzzy similarity matrix, and then clustering. The final fuzzy similarity matrix is constructed by combining two fuzzy similarity matrices calculated from two different aspects.

A comparative study on thermal stability of hybrid (organic / inorganic) electrolytes for dye-sensitized solar cells (DSSCs) in various ethylene oxide oligomers / silica based gelly matrices, containing also some efficiency-promoter additives is presented. Using thermogravimetry combined with two evolved gas analytical (EGA-FTIR and EGA-MS) techniques, the released gases and volatile decomposition products from the composite electrolytes during dynamic heating programs have been identified and monitored. First methanol (arising from condensation of tetramethoxysilane, TMOS) and acetonitrile (solvent) are evolved followed by elongated release of 4-tert-butylpyridine, than carbonyl sulfide, which is one of the degradation products of guanidinium thiocyanate, and various alkyl iodides, as well as iodine, later various oxidized species with >C=O groups (arising from oxidative degradation of oligo(ethylene glycolic) parts, ammonia (originated from guanidine) have been observed and traced during the accelerated heating tests, before final burning out of the organic residue with CO2 evolution. Thermal behavior of pure guanidinium thiocyanate, one of the most important additives improving thermal stability of Grätzel type solar cells (DSSCs), combined with identification of its eight gaseous decomposition products and their release pattern is also reported.
Simulation and Analysis of a Quadrotor UAV while Landing.

Unmanned aerial vehicles are widely used in military and civilian fields in recent years. Quadrotor Unmanned Aerial Vehicles (UAV) have high advantage among other UAV’s, in different categories, due to their ability to hover, and Vertical Take-Off and Landing (VTOL) capability. The mathematical simulation method can be adopted for analysis of UAV. The simulation method can reduce the flight period, cost and risk and improve its performance while Vertical take-off and landing (VTOL). While landing of UAV, the kinetic energy of vehicle is absorbed by UAV frame resulting in high stress concentration. The stresses are also produced in other parts of the UAV. The effect of the landing loads and stresses on the airframe of the quadrotor unmanned air vehicle must be completely understood and the UAV must be designed accordingly in order not to damage during landing.These stresses can be analyzed by simulation method to ensure the sustainability of UAV structure. This work includes structural and frequency analysis for Quadrotor UAV chassis.
Amino Acid-Mediated Synthesis of CsPbBr3 Perovskite Nanoplatelets with Tunable Thickness and Optical Properties

Metal halide perovskites (MHPs) have recently attracted considerable attentions due to their remarkable optoelectronic properties. Colloidal synthesis of MHPs provides a versatile route to precisely control their dimensionality and the related optoelectronic properties. Herein, we report on amino acid (Trp)-mediated synthesis of quasi-two-dimensional CsPbBr3 perovskite nanoplatelets (NPLs) with well-controlled and tunable thickness. The number of layers (n) could be finely tuned from 4 to 12 by simply adjusting Trp concentration, leading to gradual red shift of their photoluminescence (PL). This allows us to directly correlate their thickness with the band gap energy in the quantum confinement regime, which is in good agreement with theoretical model. We found that Trp is the only hydrophobic amino acid to promote the formation of 2D CsPbBr3 NPLs. The use of Trp derivatives for CsPbBr3 nanocrystal synthesis indicates that the carboxyl group, amine group, and indole ring of Trp act synergistically on CsPbB.

Nanopartikel Fe 3 O 4 berbasis pasir besi doping ion Zn 2+ telah berhasil disintesis melalui metode kopresipitasi pada suhu rendah. Bahan-bahan yang digunakan adalah pasir besi sebagai bahan utama, ZnCl 2 , HCl dan NH 4 OH. Karakterisasi dilakukan menggunakan X-Ray Flourescence (XRF), X-Ray Diffraction (XRD) dan kapasitansi meter digital AD5822. Hasil uji XRF menunjukkan bahwa komposisi unsur sampel sesuai dengan stoikiometri. Identifikasi fasa menggunakan sotware High Score Plus dan DDView+PDF2 menunjukan bahwa seluruh sampel terbentuk dalam fasa spinel kubik. Hasil analisis refinement menggunakan sofware Reitica menunjukkan semakin banyak doping ion Zn 2+ pada Fe 3 O 4 , nilai parameter kisi kristal juga meningkat dengan ukuran kristal berorde nanometer. Hal ini sebagai konsekuensi dari pengaruh ukuran jari-jari ion Zn 2+ yang menggantikan ion Fe 2+ . Sementara hasil uji dielekrisitas menunjukkan dengan meningkatnya doping ion Zn 2+ pada Fe 3 O 4 , nilai dielektrisitasnya juga meningkat. Mekanisme ini adalah fenomena polarisasi ionik sebagai akibat dari menurunnya volume kristal dan jarak antar atom, sehingga momen dipol semakin besar.
