Relationship between Teacher’s Level of Training in Information Communication and Technology and Students’ Academic Achievement in Physics in Makueni County, Kenya

: Recent studies have found out that the use of Information communication and Technology (ICT) in teaching makes learning enjoyable thereby leading to improvement of academic achievement by the learner. Teachers who have high ICT skills have been found to demonstrate high levels of competency in using ICT in teaching. To get sufficient skills in the use of ICT, one has to undergo training or get exposed to the use of ICT through interaction with peers or through self-learning on the internet. This study sought to investigate the relationship between teacher’s level of ICT training and how it influences a learner’s academic achievement in physics in Makueni County. Stratified random sampling was applied to select a sample of 60 schools from a total population of 375 schools. The research used descriptive survey design where participants answered questions administered through interviews and questionnaires. Microsoft (MS) Excel (2010) was used to analyze the data. The objectives were analyzed through descriptive statistics and conceptual content analysis whereas analysis of variance (ANOVA) was used to test the hypotheses. From the study, it was observed that students taught by teachers who trained ICT from an ICT training college obtained higher scores than students taught by teachers who took ICT as a unit in teacher training colleges. It was also observed that students taught by teachers with high levels of ICT training obtained a high means core than students taught by teachers with low level of ICT training. However, the study found out that students taught by teachers who were trained to use physics software produced students with low mean score than teachers who were not trained to use any physics software. From the findings, it was concluded that the teacher’s level of ICT training affects student’s academic achievement in physics with teachers who have high level of ICT training producing students who have a higher performance than students taught by teachers with low level of ICT training. From these findings, it was recommended that ICT training centers which specialize in training teachers be established, the ministry of education to organize more frequent in-service training (INSET) programs to enable teachers acquire more ICT skills and lastly, more research to be done on the influence physics software’s have on the academic achievement of students in physics.
Tricked into Supporting: A Study on Computational Propaganda Persuasion Strategies

The study reported in this paper aims to theoretically and empirically explore computational propaganda (CP) – a systematic process of political misinformation perpetrated on social networking platforms by automated agents with the aim of increasing support for specific political stances – focusing in particular on the factors determining its potential effectiveness. The claim maintained throughout this paper is that, among the possible factors determining this effectiveness, a pivotal one is represented by the design of CP messages themselves. Indeed, the hypothesis underlying this investigation is that the way CP content is created and presented is not casual, but deliberately designed to embed in it a set of persuasion strategies aimed at triggering a specific cognitive deliberation: considering misinformation as factual. Drawing from the Dual Process Theory of Cognition, the argument proposed is that info-cues contained in CP messages play a pivotal role in determining the likelihood of CP effectiveness. To test this hypothesis, a two-step analysis characterized by a mixed-method strategy has been implemented. To identify and collect CP messages, a machine learning algorithm able to perform bot-detection has been developed, while to analyze the content of those messages, a combination of qualitative and quantitative text analysis techniques has been employed. Lastly, preliminary results are presented and future work discussed.
Identification of Ryanodine Receptor 1 (RyR1) Interacting Protein Partners Using Liquid Chromatography and Mass Spectrometry

Ryanodine receptor 1 (RyR1) is a homotetrameric calcium channel located in the sarcoplasmic reticulum (SR) of skeletal muscle. We employed metal affinity chromatography followed by liquid chromatography mass spectrometry from HEK-293 cells to purify affinity tagged cytosolic RyR1, with interacting proteins. In total, we identified 703 proteins with high confidence (>99%). Of the putative RyR1 interacting proteins, five candidates [calcium homeostasis endoplasmic reticulum protein (CHERP), ER-golgi intermediate compartment 53kDa protein (LMAN1), T-complex protein (TCP), phosphorylase b kinase (PHBK) and four and half LIM domains protein 1 (FHL1)], were selected for interaction studies. Immunofluorescence analysis showed that CHERP colocalizes with RyR1 in the SR of rat soleus muscle. Calcium transient assays in HEK293 cells over-expressing RyR1 with siRNA suppressed CHERP or FHL1, showed reduced calcium release via RyR1. In conclusion, we have identified RyR1 interacting proteins in CHERP and FHL1 which may represent novel regulatory mechanisms involved in excitation-contraction coupling.
Does CSR Disclosure Improve Firm’s Access To Finance And Reduce Firm Risk?

This study aims to find how CSR disclosure affects firm’s access to finance and firm risk, using empirical studies. The research uses secondary data from annual report and sustainability report listed in the manufacturing sector in Indonesia Stock Exchange (IDX). By using the purposive sampling method, a sample of 41 firms was obtained or 164 firm-years from 2015 to 2018. The study measures CSR disclosure by both quantity and quality to reflect the overall comprehensibility of the report. Data analysis is done with multiple linear regression method. The result shows that CSR quantity and quality increase a firm’s access to finance and reduce firm risk. Extensive and high-quality CSR reports are more favourable to investors, fund providers, and the society as a whole. It is because CSR improves a firm’s reputation and reduces agency problem. This supports legitimacy and agency theories. The limitation of this study is that it uses content analysis for CSR measures, so that there is an element of researcher's subjectivity. The results of these findings can be used as a consideration for companies to improve CSR disclosure and policy setting for regulators.

Application of Renewable Kenaf Cellulose Nanofiber as a Temephos Nanocarrier for Control of Aedes Aegypti (Diptera: Culicidae) Larvae

Larviciding is an effective control method in managing mosquito-borne diseases. However, current carrier materials used in larvicides formulation raised environmental concerns due to its non-renewable origin. Herein, our study aimed to evaluate the application of the renewable source kenaf cellulose nanofiber (KCNF) impregnated with temephos for the control of Aedes aegypti mosquito larvae. The morphology of KCNF+T was examined using field emission scanning electron microscope (FESEM) and transmission electron microscopy (TEM) while the quantity of temephos impregnated, released, and retained on the fibers upon dispersion in water were determined using high performance liquid chromatography (HPLC). Subsequently, the bioefficacy of the KCNF+T was evaluated against Ae. aegypti larvae. The FESEM and TEM micrograph verified the presence of temephos on the KCNF after the impregnation. HPLC analysis showed the amount of temephos impregnated on KCNF was 97 % of the 0.1 mg temephos. Upon dispersion in water, KCNF+T released 53% temephos and the retention of temephos on KCNF+T gradually decreased to 30, 17 and 7 % on the first, third and fifth month, respectively. The exposure of Ae. aegypti larvae to KCNF+T at concentration 0.006 to 0.01 mg/L was effective at 17 - 25 folds in killing Ae. aegypti larvae compared to temephos without KCNF. Microscopy examination revealed accumulation of the KCNF on the larval appendages. Overall, our study demonstrated that KCNF made from renewable source is an effective nanocarrier of temephos for the control of Ae. aegypti mosquito larvae.
Assessment of Dietary Pattern for Medical Students in Benghazi University in Libya

Background: We assessed the dietary pattern of undergraduate medical students. Were transition of students to college may increase the opportunity for them to choose the type and the amount of food, because the collage a new society and find less food time during study, may results in a good or bad choice of food. If students are unaware of the nutritional needs to maintain a healthy body weight, this can cause under or over weight and other health problems. Methods: The study applied a cross-sectional, descriptive study design, sample size of 455 male and female students their ages (19-30), from four medical faculties including Medical, Dental, public health, pharmacy, and medical technology of Benghazi University in Libya, data were collected using a self-completed questionnaire, the height and weight were recorded, BMI and energy requirements was calculated accordingly. Results: The study presented the majority of students participating from various medical specialties, in fourth year of medical & public health collage , and their ages between 19-30 years and gender is 51% female and 49% male. The body mass index of 68.4% of students between 18.5-24.9 (normal), 22.9% had 25-29.9 (over weight) & 5% of students were 30 or more (obese), while 3.7% was BMI less than 18.5 (underweight). The Correlation between BMI and gender among medical students (N=455) were significantly associated 36% n163 of females & 33% n 148 of males were preferred to normal BMI (P=0.014). 61.3% of college students were sedentary physical activity. Gender were found to be significantly associated with physical activity level, sedentary & moderate active of physical activity more frequent in Females, 32.5% & 15.6% respectively, but extreme activity more in male n 27 (5.9%) compared by female n12 (2.6 %) (P= 0.032). 80% of students were F & V consumptions in less than 5 servings a day. BMI was not showed significantly associated with F & V consumption (p= 0.772). also their consumptions of total energy, carbohydrates and fats less than the recommended daily allowance (RDA), The correlation of energy and carbohydrate with physical activity is not significantly associated (p= 0.756) & (p=0.718) respectively. The energy and carbohydrate consumption are "less than requirements" in sedentary life style, 54.7% & 39.8% respectively; while the protein consumption more than RDA. The protein and fat are significantly associated with physical activity were (p=0.032) & (p=0.005) respectively, were the consumption "more than requirements" in sedentary life style 44% & 31% respectively. Conclusions: The study demonstrated that most medical students were sedentary lifestyle. Fruit and vegetables consumption were less than the RDA by WHO, and they were depended on proteins in their diet more than carbohydrates and fats. Medical students need intensive nutritional educational programs and they should be encouraged to promote healthy eating habits.
Improved acid trap methodology for determining ammonia volatilization in wind tunnel experiments

Abstract: Nitrogen loss through ammonia volatilization is an environmental and economic concern. When acid traps are used with wind tunnels to measure ammonia volatilization, loss of solution volume is observed. As the loss mechanism affects volatilization estimates, a field study was conducted to determine if solution loss from acid traps was due to either selective loss of water through evaporation, loss of bulk solution, or a combination. Two methods for calculating air flow volume through the acid traps were also examined. Solution losses from acid traps averaged 40 mL d-1 (±9.2 mL) from an initial 100 mL, and ammonium concentration increased in close accordance with the dilution–concentration relationship for aqueous solutions. Hence, solution loss was due to evaporation, with virtually no ammonium loss, confirming that the flux calculations using corrected acid trap volumes are required. Failure to correct for the reduced volumes resulted in 9%–224% overestimation of ammonium concentrations. Air flow volumes through acid traps were underestimated by 18.5% when initial and final air flow rates were used compared with continuous cumulative flow measurements. Using cumulative flows and accounting for evaporation loss from acid traps help ensure that treatment differences are not masked by the inherent variability in field-based measurements.
Corrupção e religiosidade: uma análise cross-country mediada pela qualidade da contabilidade

RESUMO O objetivo deste artigo foi identificar a associação da religiosidade com a corrupção, mediada pela qualidade da contabilidade. Estudos examinaram as relações entre religiosidade e qualidade da contabilidade, religiosidade e corrupção, e qualidade da contabilidade e corrupção. Não foram identificadas evidências do papel combinado da religiosidade e da qualidade da contabilidade na corrupção. O estudo contribui para o entendimento da influência da religiosidade como norma social na decisão dos gestores, o que, consequentemente, impacta a qualidade da contabilidade e a corrupção, ampliando o conhecimento sobre os mecanismos capazes de afetar a corrupção. Fundamentando-se na Teoria das Normas Sociais e respaldando-se em estudos sobre a relação entre religiosidade e qualidade da contabilidade, que também se ampararam nessa teoria, foi possível discutir a influência da religiosidade nas decisões dos gestores, com reflexos na qualidade da contabilidade e na corrupção. A amostra é formada por 36 países. Para o tratamento dos dados do período de 2010 a 2014, foi utilizada a modelagem de caminho por mínimos quadrados parciais. Evidências apontaram que maior religiosidade está associada à menor qualidade da contabilidade e que, em conjunto, associam-se com maior corrupção. O resultado pode ser explicado pelo coletivismo, característica de ambientes mais religiosos. Ele favorece o desenvolvimento do conluio, o qual tem potencial para prejudicar a qualidade da contabilidade e facilitar a ocorrência de corrupção. Além disso, ambientes mais religiosos estão associados a menor monitoramento, o que pode encorajar a manipulação de informações contábeis e a corrupção. O estudo demonstra que o efeito combinado da religiosidade com a qualidade da contabilidade no combate à corrupção não se apresentou eficiente. As evidências permitem, ainda, avaliar a influência da religiosidade nas decisões dos gestores, como norma social, com reflexos na qualidade da contabilidade e na corrupção.
Does Earthquake Stress Drop Increase With Depth in the Crust?

We combine earthquake spectra from multiple studies to investigate whether the increase in stress drop with depth often observed in the crust is real, or an artifact of decreasing attenuation (increasing Q) with depth. In many studies, empirical path and attenuation corrections are assumed to be independent of the earthquake source depth. We test this assumption by investigating whether a realistic increase in Q with depth (as is widely observed) could remove some of the observed apparent increase in stress drop with depth. We combine event spectra, previously obtained using spectral decomposition methods, for over 50,000 earthquakes (M0 to M5) from 12 studies in California, Nevada, Kansas and Oklahoma. We find that the relative high‐frequency content of the spectra systematically increases with increasing earthquake depth, at all magnitudes. By analyzing spectral ratios between large and small events as a function of source depth, we explore the relative importance of source and attenuation contributions to this observed depth dependence. Without any correction for depth‐dependent attenuation, we find a systematic increase in stress drop, rupture velocity, or both, with depth, as previously observed. When we add an empirical, depth‐dependent attenuation correction, the depth dependence of stress drop systematically decreases, often becoming negligible. The largest corrections are observed in regions with the largest seismic velocity increase with depth. We conclude that source parameter analyses, whether in the frequency or time domains, should not assume path terms are independent of source depth, and should more explicitly consider the effects of depth‐dependent attenuation.
Results of growing parsley using aquaponics method

The article presents the results of experiments on the use of the aquaponics method. Aquatic animals release products toxic to them themselves: nitrogenous, phosphorus, potassium compounds, carbon dioxide. The accumulation of these substances in water is the main problem as in closed industrial aquaculture. The same substances are absolutely necessary in hydroponics and they are added to water to obtain nutrient solutions for plants. Given that environmentally friendly products are increasingly popular and demand for them is constantly growing, there are prospects for introducing this innovation in the southern regions of Russia. Due to an increase in parsley yields in the aquaponic plant by 7.3%, an additional profit was received 4.8 rubles from 1 square meters.
Tulburările de refracţie la copii

Conform estimărilor curente, la nivel global există aproximativ 150 milioane de persoane cu o tulburare de refracţie necorectată, însumând 27% din populaţia mondială. Dintre aceştia, aproximativ 1,4 milioane sunt copii şi prezintă o formă mai uşoară sau mai gravă de disfuncţie vizuală secundară viciilor de refracţie. Începând cu 1990, afecţiunile oculare considerate a fi o problemă de sănătate publică în rândul copiilor şi care produc disfuncţie vizuală sunt erorile refractive, având o prevalenţă de până la 43%. Maturarea vederii se produce în copilăria precoce, când toate simţurile şi abilităţile motorii conlucrează pentru achiziţia limbajului, a primelor impresii despre mediul înconjurător şi a tuturor elementelor care definesc persoana în sine. Vederea este un sistem percepţional contributiv în dezvoltarea cognitivă, socială, senzorio-motorie şi în acumularea de informaţii despre mediul înconjurător. În primii ani de viaţă, copilul descoperă activităţi tot mai complexe, fiind necesare abilităţile de schimbare a fixaţiei în spaţiu de la un punct la altul şi o motilitate binoculară normală.
Autonomous Bus Fleet Control Using Multiagent Reinforcement Learning

Autonomous buses are becoming increasingly popular and have been widely developed in many countries. However, autonomous buses must learn to navigate the city efficiently to be integrated into public transport systems. Efficient operation of these buses can be achieved by intelligent agents through reinforcement learning. In this study, we investigate the autonomous bus fleet control problem, which appears noisy to the agents owing to random arrivals and incomplete observation of the environment. We propose a multi-agent reinforcement learning method combined with an advanced policy gradient algorithm for this large-scale dynamic optimization problem. An agent-based simulation platform was developed to model the dynamic system of a fixed stop/station loop route, autonomous bus fleet, and passengers. This platform was also applied to assess the performance of the proposed algorithm. The experimental results indicate that the developed algorithm outperforms other reinforcement learning methods in the multi-agent domain. The simulation results also reveal the effectiveness of our proposed algorithm in outperforming the existing scheduled bus system in terms of the bus fleet size and passenger wait times for bus routes with comparatively lesser number of passengers.
Teaching the Construction of Feminist Ideology to EFL Learners: A Corpus Approach

Corpus Linguistics has gained much importance, and it is now continually been applied in linguistics as well as in literature. This paper aims to investigate the use of corpus linguistics in teaching literature to students. This research has used a both qualitative and quantitative approach. The question it probes to find out is how literature (Feminist Theory) can be taught to students by using the Simple Concordance Program (4.09). The results are: different words, which were supporting the feminist ideology, are extracted from the word list of the sample, and then, feminist analysis is done, according to their occurrence in the phrase and sentences.
WEIGHTED ESTIMATES FOR CERTAIN ROUGH OPERATORS WITH APPLICATIONS TO VECTOR VALUED INEQUALITIES

Under certain rather weak size conditions assumed on the kernels, some weighted norm inequalities for singular integral operators, related maximal operators, maximal truncated singular integral operators and Marcinkiewicz integral operators in nonisotropic setting will be shown. These weighted norm inequalities will enable us to obtain some vector valued inequalities for the above operators.
