Radiation Mechanisms and Physical Properties of GeV γ ?> -Ray Source GB 1310+487

With the adoption of the synchrotron self-Compton (SSC) + external Compton (EC) model, investigation has been conducted on the radiation mechanisms of the GeV-bright active galaxy GB 1310+487 through modeling its quasi-simultaneous spectral energy distributions in active and quiescent states. We find that from the flare states to the post-flare state, the magnetic field (B) has experienced a gradual increase, whereas the electron spectrum’s prefactor (N0) and break energy ( γ br ? > ) decrease accordingly. The model indicates that the energy of the Poynting flux may be used to accelerate electrons. As for the GeV emission in the source, it is dominated by the EC process while the SSC contribution is negligible. Varying energy distribution of the emitting electrons, rather than location of the radiation blob, appears to be the driving factor for the observed changes in EC emission. Despite the similar total jet power and the same likely energy carrier (cold protons), the radiation efficiency of GB 1310+487 is lower than what is found in bright Fermi blazars.
Liquidity Capacity and Financial Performance of Commercial Banks in Kenya

Purpose: The objective of the study was to assess the impact of liquidity capacity on the financial performance of commercial banks in Kenya. Methodology: This study employed the explanatory research design. The 42 Kenyan commercial banks were the study's target population. The essential financial data for analysis was extracted and compiled using a data collection routine from the yearly reports. Panel data was mined from 42 commercial banks for six years between 2012 and 2018. The data were assessed by employing descriptive statistics as well as inferential statistics. Descriptive statistics employed involved the standard deviation, median, and average. Inferential statistics used involved panel regression. The data analysis was aided by STATA software. Findings: The findings from the regression analysis indicate that Net Stable Funding and Liquidity Coverage exert a significant positive impact on the financial performance of commercial banks in Kenya. Conversely, provisioning for Non-Performing Loans, Liquidity Gap, and Provisioning for Nonperforming Loans demonstrate a notable negative effect on the financial performance of commercial banks in the country. Moreover, the study reveals that bank competition plays a significant moderating role in the relationship between liquidity capacity and the financial performance of commercial banks in Kenya. Unique Contribution to Theory, Practice and Policy: The study was anchored on Anticipated Income Theory and Liquidity Preference Theory. The study recommended that the regulatory body for commercial banks, the CBK, facilitates open channels of communication between policy makers and senior management of commercial banks in Kenya. This discussion is critical to ensuring that the monetary policies developed are practical and beneficial to the expansion of the commercial banking industry. Lastly, the study suggests that all commercial banks in Kenya integrate considerations of liquidity costs, benefits, and risks into their performance measurement, pricing, and approval processes for significant business activities.
Temporal Impacts of Problematic Social Media Content on Perceived Employee Hirability

ABSTRACT Job applicants’ social media postings and presence can impact employers’ perceptions during the hiring process. The current study expands this line of inquiry, exploring the effects of both message characteristics (i.e. post temporality) and individual characteristics (i.e. hiring manager’s view about individuals’ ability to change over time). Results of a 2 (problematic content: present v. absent) × 3 (post temporality: recent v. 2 years ago v. 5 years ago) experiment (N = 220) revealed the negative main effect of the presence of problematic social media content was moderated by the temporality of the post: More recent posts more substantively impacted perceptions of person-job fit. This moderation effect was further moderated by the manager’s incrementalism: the belief people’s personalities can change over time. Similar patterns of effects were not identified for broader perceptions of the applicant’s general employability.
The fluidity of Finnish youths’ Personal worldviews

ABSTRACT This article aims to understand the personal worldviews of Finnish youths. The fluidity of young people’s personal worldviews has been highlighted in a number of previous studies, and this study presents more information by focusing on possible spiritual and religious elements in the personal worldviews of young people and on the influences that affect their personal worldviews. The data of this study consist of a quantitative questionnaire acquired from Finnish upper secondary school students (N = 973). The results show that young people’s personal worldviews are not fixed but are fluid and that nominal membership in a religious community does not explain their worldviews. Young people do not see religion as important to them, and they see religion more as a part of culture and their environment than as a part of their personal worldview. The most important sources of information for the construction of their personal worldview are school and the Internet.
The Effect of Anaesthesia Management with Different Fresh Gas Flows on Cognitive Functions of Geriatric Patients: A Randomized Double-blind Study

Objective: The present study aimed to compare the effects of two different fresh gas flows (FGFs) (0.5 L min-1 and 2 L min-1) applied during maintenance of anaesthesia on recovery from anaesthesia and early cognitive functions in geriatric patients. Methods: In this prospective, randomised, double-blind study, sixty patients were divided into two groups according to the amount of FGF. Minimal-flow anaesthesia (0.5 L min-1 FGF) was applied to group I and medium-flow anaesthesia (2 L min-1 FGF) was applied to group II during maintenance of anaesthesia. Following the termination of inhalation anaesthesia, recovery times were recorded. The evaluation of cognitive functions was performed using the Addenbrooke’s Cognitive Examination (ACE-R). Results: There was no significant difference between the two groups in terms of demographic characteristics and recovery (P > 0.05). There was no significant difference between the two groups in terms of the preoperative day, the first postoperative day, and the third postoperative day; ACE-R scores (P > 0.05). In group II, on the third postoperative day ACE-R scores were found to be significantly lower than the preoperative ACE-R scores (P=0.04). In group II, third postoperative day ACE-R memory sub-scores (14.53 ± 3.34) were found to be significantly lower than preoperative ACE-R memory sub-scores (15.03 ± 3.57) (P=0.04). Conclusion: In geriatric patients, minimal-flow anaesthesia was not superior to medium-flow anaesthesia in terms of recovery properties and cognitive functions. Keeping in mind that hypoxaemia and changes in anaesthesia levels may occur with the reduction of FGF, both minimal- and medium-flow anaesthesia can be applied with appropriate monitoring without adverse effects on recovery and cognitive functions.
Academic Motivation and Engagement: A Correlational Study of Students’ Perspective at Secondary School Level

The purpose of the quantitative correlational study was to investigate the association between students' academic motivation and academic engagement. This study included 600 10th-grade students who were selected at random from 20 secondary schools in the district Lahore. The data from selected students were gathered using two research instruments. The independent sample t-test, Pearson r, and linear regression were used to analyze the data. As r =. 781 (p > 0.01), the findings demonstrated a strong and significant correlation between academic motivation and students' academic engagement. As a result, students' academic engagement was positively impacted by academic motivation. Academic motivation and academic engagement of students differed significantly by gender. Policy makers, teachers, and scholars are advised to pay particular consideration to each learner's level of academic engagement since it affects students' engagement with schoolwork.
Machine Learning in Higher Education: Students’ Performance Assessment Considering Online Activity Logs

Machine learning in Education is receiving more attention from researchers as the number of students at all levels globally is increasing. To ensure students’ success in K-12 educational institutions and higher education institutions work needs to be done to assist students, teachers/professors, parents, and all stakeholders to provide the support that students need. The need and motivation for such systems are very well-established and thus the aim of this work is to develop a system based on modified machine learning models to automatically predict students’ performance and subsequently identify students at risk. The DEEDs dataset is used in this study. Novel features were extracted and applied to well-known classifiers some of which are ensemble classifiers. These classifiers were also combined with base learners such as bagging and boosting. The problem was divided into three scenarios; binary classification of the pass and fail, three class scenarios, and four class scenarios. It was shown that ensemble methods combined with base learners of boosting and bagging significantly increase the accuracy for binary classification, slightly increase accuracy for three class problems, and have no significance in increasing the accuracy when the problem is 4 classes. The ensemble algorithm of bagging and boosting FDT achieved an accuracy of 98.25% for binary classification and 89.47% for three classes. The standard ensemble FDT achieved an accuracy of 77.19% for four classes. The results obtained for binary classification were compared with results reported in the extant literature using the same dataset proving that the proposed modified algorithms achieved better results than similarly proposed methods. The three-class and four-class results could not be compared because according to the author’s knowledge, there are no research papers published for the same dataset for multi-class classification.
Probability Density of Lognormal Fractional SABR Model

Instantaneous volatility of logarithmic return in the lognormal fractional SABR model is driven by the exponentiation of a correlated fractional Brownian motion. Due to the mixed nature of driving Brownian and fractional Brownian motions, probability density for such a model is less studied in the literature. We show in this paper a bridge representation for the joint density of the lognormal fractional SABR model in a Fourier space. Evaluating the bridge representation along a properly chosen deterministic path yields a small time asymptotic expansion to the leading order for the probability density of the fractional SABR model. A direct generalization of the representation of joint density often leads to a heuristic derivation of the large deviations principle for joint density in a small time. Approximation of implied volatility is readily obtained by applying the Laplace asymptotic formula to the call or put prices and comparing coefficients.
Infinity, infinite processes and limit concepts

This article seeks to recover a neglected chapter in the historical and theoretical background of social theory in general and critical theory in particular with a view to refining the understanding of the presuppositions of a cognitively enhanced critical social science appropriate to our troubled times. For this purpose, it offers a brief reconstruction of the mathematical-philosophical tradition from ancient to modern times by extrapolating that part of it that is marked by the ideas of infinity, infinite processes and limit concepts. It gives suggestive indications not only of how these ideas relate to extant social-theoretical thought, but especially also of the two related cognitive directions – the weak-naturalistic and the socio-cultural – in which such thought is currently challenged to go.
CENTRAL LIMIT THEOREM OF MIXED TYPE FOR TRANSFORMATIONS WITH QUASI-COMPACT PERRON-FROBENIUS OPERATORS

We consider a nonsingular transformation whose Perron–Frobenius operator is quasi-compact on an appropriate Banach algebra. We establish the central limit theorem of mixed type with a nice convergence rate for a real-valued observable in the Banach algebra. As an application, we show that generalized piecewise expanding maps on the unit interval with Hölder continuous derivatives and the Banach algebra of Lebesgue integrable functions with a version of bounded p-variation satisfy our conditions if p is not smaller than the reciprocal of the Hölder exponent of the derivatives.
Sporting Excellence in Malta Viewed Through an Ecological Systems Lens: A Qualitative InvestigationInto Athletes Attitudes, Aspirations and Feelings

Many different personal, social, and structural factors determine the experienceand success of teams in international tournaments. This study aimed to explore some ofthese factors by looking at similarities and differences in the experiences of two variedlysuccessful Maltese teams involved in international competitions. Athletes from SpecialOlympics Malta and a Maltese male senior national team participating in the World Gamesand European Championships respectively were recruited to the study. A total of 11 athletesof Maltese nationality, aged 14-38 years, were interviewed before and after their respectivecompetitions and provided audio diary entries about their experiences during thecompetitions. Semi-structured interview data and diary entries were transcribed verbatimand analysed using interpretive phenomenological analysis. Results found contrastingattitudes, aspirations, and feelings among participating athletes. How these themesintersect with various layers of influence using an ecological system lens is discussed andprovides an insight into what appropriate support structures may benefit Maltese athletesin the future.
An experimental investigation of flame length of alcohol and N-heptane pool fires under air cross condition

ABSTRACT In this paper, the effect of airflow speed on flame length of liquid pool fires has been experimentally studied based on a small-scale wind tunnel, where the airflow speed was varied from 0 to 2.93 m/s during the tests. Different sizes of the pool with 2, 3, 4, 6, 8, and 10 cm diameter were considered. The experimental results show that with increase of , the non-dimensional flame length of alcohol pool fire firstly increases and then decreases after exceeds 8.0, while the non-dimensional flame length of n-heptane pool fire increases with increase of . It was also found that the flame length response to the airflow speed correlates to heat release rate of the fire, which was seriously influenced by combustion efficiency. A model was also developed for predicting flame length of a pool fire influenced by airflow with .
Detection of magnetic circular dichroism with subnanometer convergent electron beams

The electron energy-loss spectroscopy technique known as electron magnetic circular dichroism (EMCD) has enormous potential for quantitatively probing the magnetic behavior of materials on the nanoscale. However, the requirement for mostly parallel illumination conditions greatly complicates the extraction of EMCD signals from surface areas under a few square nanometers, because scanning probe methods are limited to around this spatial resolution by the need for higher convergence angles. Here we propose theoretically and demonstrate experimentally that EMCD detection is feasible with convergence angles that are sufficiently large even for atomic resolution spectroscopy. Utilizing scanning transmission electron microscopy we experimentally detect a clear EMCD signal from a 50-nm-thick sample of bcc iron using a convergence semiangle of 8 mrad at 300 keV acceleration voltage, resulting in a probe size of approximately 2 \AA{}. We subsequently estimate the number of chirally scattered electrons needed for an unambiguous detection of the EMCD signal and present a method to quantify confidence in signal detection.
Emotional Intelligence and Job Stress: In Its Influence on Teachers’ Performance

The competency test results for state high school teachers who served in Rokan Hilir Regency only passed 42 percent of the total teachers. This indicates that teachers’ performance is still poor. Internal and external factors both influence teachers’ performance. The internal factor is emotional intelligence, which is the ability to recognize one's own and other people's emotions. The external factor is job stress caused by the demands of the job and the work environment. The study aims to determine the impact of teachers’ emotional intelligence and job stress on teachers’ performance. This type of research uses a quantitative approach using linear regression analysis techniques. This research was conducted in all public high schools in the Rokan Hilir district. The population of this study was all teachers at public high schools who served in Rokan Hilir Regency, namely 879 teachers. Sampling using a random sampling technique with a size of 10% of the population, namely 90 teachers. The data collection technique is a non-test psychological measurement scale. Based on data analysis, the following results were obtained: Emotional intelligence has a significant influence on teachers’ performance at public high schools in Rokan Hilir Regency; Job stress has no significant effect on teachers’ performance at the State Senior High School of Rokan Hilir Regency; Job stress and emotional intelligence simultaneously have a significant impact on teachers’ performance.

Exhausted and lonely: learning in student newsrooms during COVID

ABSTRACT In a mixed methods survey (N = 323), college journalists shared their experiences of working in remote student newsrooms during the COVID-19 campus disruptions. Through the theoretical lens of Communities of Practice, findings revealed students experienced robust, but different learning in disrupted newsrooms. While students reported that their ability to cultivate and learn with a community suffered, they still reported the formation of their identities as journalists and the development of meaning. Analysis demonstrated that the survey items created statistically reliable scales for each of the four pillars and overall CoP scale. This advances the Communities of Practice theoretical framework to help describe the nature of student newsroom learning in a disrupted environment. Consistent with existing literature, this work points toward the special nature of student-run newsrooms as high-impact learning environments, however, the isolation that came as a natural outgrowth of the lack of community contributed to students’ struggles with mental health. These findings also underscore additional practical implications of young journalists learning and refining their craft in isolated spaces. Reporting remotely required heightened self-sufficiency and resiliency, but also amplified feelings of burnout, low morale, and mental exhaustion.
Quantum coherence in the integer quantum Hall regime

This work is devoted to the study of decoherence process in the integer quantum Hall regime. In this regime, the current is carried by one dimensional chiral edge channel. These electronic beams are then controlled with mesoscopic beam splitters, the quantum point contacts (QPC). A precise tuning of these QPC enables us to obtain interferences of the conductance. The study of the visibility of these oscillations probes the coherence of the system. In a first part, we have studied the visibility as a function of the bias when the inner edge state is reflected and have observed a lobe structure. We have shown that for a single side lobe, a Gaussian phase averaging can explain this lobe structure. When the inner edge state is transmitted, the visibility decreases monotonously as a function of the bias: we have shown that it resulted from coupling between the inner and outer edge state. In a second part, we have studied the temperature dependence of the visibility in MZIs of different sizes, have extracted for the first time a measurement of the coherence length in the quantum Hall regime and have shown its proportionality to 1/T. We were interested then in the origin of this finite coherence length. We have shown that thermal fluctuations of the inner edge state combined with the coupling between the inner and outer edge state were the source of decoherence. In a last experiment, we have achieved the first experimental realization of the theoretically widely used voltage probe.
The Role of the School Principal in Burnout and Job Satisfaction of Secondary School Teachers

This research aims to identify the role of school principals in burnout and job satisfaction of Greek teachers that are working in both primary and secondary education. The aim was covered through quantitative research with a structured and online distributed questionnaire used as the main research tool. The research participants were 155 schoolteachers coming from primary and secondary Greek school units. They were collected by using convenience sampling and the avalanche method. For the distribution of the questionnaire, the Google Forms platform was used, and for the statistical analysis. The main research results showed that transactional and transformational leadership are more implemented in Greek schools, than laissez-faire leadership style. Teachers’ levels of job burnout are positively affected by laissez-faire leadership and negatively affected by the two positive leadership styles. On the contrary, transformational, and transactional leadership has a positive impact on job satisfaction levels and a negative impact on teachers’ burnout. Keywords: Job satisfaction; laissez-faire leadership; teachers; transactional leadership; transformational leadership
English Teachers’ Perspectives on Mother Tongue-Based Multilingual Education

Researchers have shown several benefits of MTB-MLE and several challenges in its implementation. In Nepal, language policies are in the state of flux. Therefore, against the theoretical backdrop, this paper is an attempt to find out the perceived differences between MTI and MTB-MLE, outcomes of MTB-MLE, challenges of MTB- MLE and ways to overcome the challenges. The study adopted convenience sampling and semi-structured interview for data generation. It presents a relevant literature that guided the study to reach the conclusions. The study has thematically analysed the data and shown that MTB-MLE is useful to preserve people’s identities, to enable people to cope up with global market, and to preserve the dying languages. Despite the challenges in the implication of MTB-MLE, the study has given the possible ways to overcome the challenges. The study has clearly mentioned its limitations and shown possibilities for further research as well.
