EFFECT OF PORTFOLIO MANAGEMENT ON THE FINANCIAL PERFORMANCE OF LISTED INSURANCE FIRMS IN THE NAIROBI SECURITIES EXCHANGE, KENYA

The performance of listed insurance companies in Kenya has over time been unstable, despite its contribution to Kenya’s GDP. Whereas the firms have diversified investment asset portfolios, the financial performance of these companies has generally remained low; as evidenced by inconsistent revenues. The purpose of this paper is to establish the relationship between portfolio management and the financial performance of the listed insurance firms in Nairobi Securities Exchange (NSE), Kenya. The study has been guided by Modern Portfolio Theory, allowing for the integration of mixed securities. correlational research design has been employed on a target population of six (6) listed insurance companies at the Nairobi Securities Exchange. census technique of data collection to obtain secondary data through the document review method was used. Analyzing data through descriptive and inferential statistics, the following results were obtained; showing a positive significant effect of both portfolio size (β = 0.4859, p = 0.002) and portfolio asset allocation (β = 0.4031, p = 0.000) on the financial performance of listed insurance firms at NSE. However, the results yielded a negative but significant effect of portfolio risk (β = - 0.02546, p = 0.002) on financial performance; implying that a unit increase in portfolio size and portfolio asset allocation leads to 48.59% and 40.31% increase in financial performance of listed insurance firms, respectively. However, Portfolio risk has a negative effect, implying that a unit increase in portfolio risk leads to a 2.55% reduction in financial performance. It can therefore be concluded that portfolio management influences the financial performance of insurance firms listed at the NSE, thereby recommending that listed insurance firms in the NSE should increase the level of portfolio management by giving attention to such elements as portfolio size, portfolio asset allocation, and portfolio risk; which are important predictors of the firms’ financial performance, alongside determining the specific mix of investments generating the highest return for a given level of risk, which will lead to increased profitability.

Asymptotic behaviour of the Einstein-Yang-Mills-Higgs system in a Bianchi type I model

We study the Einstein-Yang-Mills-Higgs (EYMH) system with a positive cosmological constant in the Bianchi type I space-time with locally rotational symmetry (LRS). In particular, we consider the nonlinear interaction of the Higgs field with the Yang-Mills field coupled to an unknown gravitational field. For the considered model, from certain additional conditions (the temporal gauge and some symmetries), we derive the conservation laws for the field equations and we then deduce the exact formulation of equations in the geometric framework. Furthermore, using an iterative approch and some mathematical analysis tools, we study the above system of equations. We then establish a global existence result for the homogeneous solution and we analyse its asymptotic behaviour.
Preparation of Copper Nanoparticles Using Different Media by Pulsed Laser Ablation and Study of Their Physical Properties

In this study, copper nanoparticles (CuNPs) were prepared using the pulsed laser ablation method, and the study was conducted under the effect of changing the liquid medium (ethanol, deionized water, distilled water) with a number of pulses (700p/s) and using a (Q-switched Nd-YAG) laser. At a wavelength of 532nm and an energy of 100mJ, the results of the samples prepared in a medium (ethanol, distilled water, deionized water) showed the average radii of CuNPs (58.3, 61.6, 46.1 nm, respectively) with a spherical shape. The spectrum of copper at (3250 to 3550 ) is mainly due to the expansion of (O-H) the clear hydroxyl group and under the conditions of the three solvents (ethanol, deionized water, distilled water). The XRD results showed that the CuO nanoparticles are free of impurities and crystallized High and the crystallite size was calculated at 2theta (20.094, 19.949, 38.045) nm for the samples in (deionized water, distilled water, and ethanol), respectively.
Global Empirical Models of Wave Amplitudes and Normal Angles of Banded Plasmaspheric Hiss Obtained From Van Allen Probes Observations

The unique banded structure of plasmaspheric hiss with an upper band above ∼200 Hz and a lower band below ∼150 Hz has been recently reported. Based on observations from the twin Van Allen Probes from 15 September 2012 to 30 June 2019, we statistically investigate the global distributions of amplitude and power‐weighted wave normal angle (WNA) of banded hiss waves with respect to L, MLT, MLAT, and AE*. The results indicate that amplitudes of dayside banded hiss significantly depend on the substorm level (AE* index), while the variation of WNAs on the AE* index is slight. The WNAs of upper band hiss show a peak at L ∼ 3, while the WNAs of lower band hiss are relatively uniform at L < 4. The WNAs of both bands decrease with increasing L values at L > 4. We further develop the global empirical models of banded hiss wave amplitudes and WNAs to fit the statistical results, which show good agreement with satellite observations. These results can be essentially useful to evaluate the role of banded plasmaspheric hiss in the dynamic variations of Earth's radiation belt electrons.
The Prediction of Training Proficiency in Firefighters: A Study of Predictive Validity in Spain

The present study provides results of criterion validity in the selection of firefighters in Spain. The predictors were cognitive skills, job knowledge, and physical aptitudes, and the criterion was training proficiency. The process involves 639 candidates, but only 44 complete successfully the ion process. Our results support previous evidence showing that general cognitive ability is the best predictor of training proficiency, with an operational validity of . 57. With respect to the other predictors, job knowledge presented an operational validity of . 55 and physical tests of . 49. In addition, multiple regression analysis showed that cognitive aptitude explains 33% of the variance, but when physical aptitudes are d the explained variance increases to 50%. If we also add job knowledge, explained variance increases to 55%. Our study offers recent results of criterion validity in a barely investigated job, gathered in a ry other than the one prior research had been carried out.
Impact of the COVID‐19 pandemic on care disruptions, outcomes, and costs in patients receiving pulmonary arterial hypertension‐specific therapy in the United States of America: An observational study

Abstract Regular expert follow‐up, risk assessment, and early therapeutic intervention minimize worsening of pulmonary arterial hypertension (PAH). COVID‐19 lockdown measures were challenging for chronic disease management. This retrospective, longitudinal analysis used US claims data (January 12, 2016 to September 11, 2021) for patients treated with PAH‐specific medication to compare in‐person outpatient and specialist visits, telemedicine visits, and PAH‐related tests during 6‐month assessment periods pre‐ and immediately post‐COVID‐19. Hospitalizations, costs, and outcomes were compared in patients with and without care disruptions (no in‐person or telemedicine outpatient visits in immediate post‐COVID‐19 period). Patients in the immediate post‐COVID‐19 (N = 599) versus the pre‐COVID‐19 period (N = 598) had fewer in‐person outpatient visits (mean 1.27 vs. 2.12) and in‐person specialist visits (pulmonologist, 22.9% vs. 37.0% of patients; cardiologist, 27.5% vs. 33.8%); and more telemedicine visits (mean 0.45 vs. 0.02). In the immediate post‐COVID‐19 period, patients were less likely to have a PAH‐related test versus the pre‐COVID‐19 period (incidence rate ratio: 0.700; 95% confidence interval: 0.615−0.797), including electrocardiograms (41.7% vs. 54.2%) and 6‐minute walk distance tests (16.2% vs. 24.9%). In the immediate post‐COVID‐19 period, 48 patients had care disruptions and, in the following year, required more hospital days than those without care disruptions (N = 240) (median 10 vs. 5 days in total) and had higher overall hospitalization costs (median US$34,755 vs. US$20,090). Our findings support the need for minimizing care disruptions to potentially avoid incremental post‐disruption healthcare utilization and costs among patients with serious chronic diseases such as PAH.
DIGITAL TRANSITION AT GOLDEN YEARS: UNCOVERING WHAT FUELS, THE SHIFT TO DIGITAL BANKING SERVICES AMONG MALAYSIAN SENIORS

The purpose of this research is to identify the factors that affect the behavioural intention to adopt digital banking among senior citizens in Malaysia. The adoption of digital banking among senior citizens is relatively low compared to the younger generation. Therefore, a survey was conducted to evaluate the factors that affect the behavioural intention to adopt digital banking among senior citizens in Malaysia. 390 questionnaires were collected from senior citizens in Malaysia's Klang Valley. Based on the data collected, correlation analysis and multiple regression analysis were used to evaluate the responses. The findings suggested that performance expectancy, effort expectancy, price value, habit, social influence, and hedonic motivation significantly influence the behavioural intention to adopt digital banking among senior citizens in Malaysia. This study's findings will allow banks, financial institutions, and policymakers to broaden their understanding of what drives the adoption of digital banking services and the obstacles that stand in the way of adopting these services. The results from this study can aid financial institutions and the banking sector in improving or enhancing these factors so that elderly banking consumers can benefit and experience the total value offered by the banking sector. The banking sector should develop digital banking services appropriately to entice senior citizens to use digital banking services. The digital banking platform should be aesthetically designed to improve senior citizens' experiences. The marketing of digital banking could be strategized based on the factors studied in this research. Article visualizations:

Early-infantile developmental and epileptic encephalopathy: the aetiologies, phenotypic differences and outcomes—a prospective observational study

Abstract In this study, we have evaluated the underlying aetiologies, yield of genetic testing and long-term outcomes in patients with early-infantile developmental and epileptic encephalopathies. We have prospectively studied patients with seizure onset before 3 months of age. Based on the clinical details, neuroimaging, metabolic testing and comprehensive genetic evaluation, patients were classified into different aetiological groups. The phenotypic differences between genetic/unknown groups and remaining aetiologies were compared. Factors that could affect seizure control were also assessed. A total of 80 children (M:F ratio—1.5:1) were recruited. The median seizure onset age was 28 days (range, 1–90 days). The aetiologies were confirmed in 66 patients (83%). The patients were further classified into four aetiological groups: genetic (50%), structural (19%), metabolic (14%; all were vitamin responsive) and unknown (17%). On comparing for the phenotypic differences between the groups, children in the ‘genetic/unknown’ groups were more frequently observed to have severe developmental delay (Odds Ratio = 57; P < 0.0001), autistic behaviours (Odds Ratio = 37; P < 0.0001), tone abnormalities (Odds Ratio = 9; P = 0.0006) and movement disorder (Odds Ratio = 19; P < 0.0001). Clonic seizures were more common in the vitamin responsive/structural groups (Risk Ratio = 1.36; P = 0.05) as compared to patients with ‘genetic/unknown’ aetiologies. On the contrary, vitamin responsive/structural aetiology patients were less likely to have tonic seizures (Risk Ratio = 0.66; P = 0.04). Metabolic testing was diagnostic in three out of 41 patients tested (all three had biotinidase deficiency). MRI was abnormal in 35/80 patients (malformation observed in 16/35; 19/35 had non-specific changes that did not contribute to underlying aetiology). A molecular diagnosis was achieved in 53 out of 77 patients tested (69%). Next-generation sequencing had a yield of 51%, while microarray had a yield of 14%. STXBP1 was the most common (five patients) single-gene defect identified. There were 24 novel variants. The mean follow-up period was 30 months (range, 4–72 months). On multivariate logistic regression for the important factors that could affect seizure control (seizure onset age, time lag of first visit to paediatric neurologist and aetiologies), only vitamin responsive aetiology had a statistically significant positive effect on seizure control (P = 0.02). Genetic aetiologies are the most common cause of early-infantile developmental and epileptic encephalopathies. Patients in the genetic/unknown groups had a more severe phenotype. Patients with vitamin responsive epilepsies had the best probability of seizure control.
Length of Hospital Stay and Its Related Factors in Iran: A Systematic Review and Meta-Analysis

Background: One of the effective indicators used to determine the efficiency and optimal use of hospital resources is the length of stay (LOS). Then, we aimed to determine LOS and its related factors in Iran. Methods: A systematic literature review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the online databases; Medline, EMBASE, Scopus, PubMed, SID, MagIran, and Medlib from 1995 to 2022 using a combination of medical subject. STATA version 11 used for data analysis. Results: Overall, 75 (cross-sectional, cohort, and case-control) reports were identified. The average length of stay in Iranian hospitals was 6.7 (95% CI: 5.32 -7.74) d. There was a significant relationship between the length of stay in the hospital and different wards of hospital (P=0.001). The average of men’ LOS was longer than women were [6.9 (95% CI: 5.32 -7.74) vs. 3.9 (95% CI: 1.67–9.41)]. Moreover, the average LOS before and after the Health Transformation Plan (HTP) in Iran has changed, so that it has increased from 5.8 (95% CI: 4.39 -7.86) to 7.1 (95% CI: 5.59 -9.25) d after HTP (P=0.30). Conclusion: The average length of stay of patients in Iranian hospitals is more than the expected index of the Ministry of Health and Medical Education and is in the unfavorable range (> four days). Moreover, considering the direct effect of the type of departments on LOS; therefore, hospital managers should pay more attention to hospital processes using new process-oriented and customer-oriented management approaches.
REVIEW OF SARS-CORONAVIRUS-2 REPERCUSSIONS ON THYROID GLAND IN THE CONTEXT OF HYPERTHYROIDISM

The thyroid gland may generate, store, and release hormones (such as Triiodothyronine and Thyroxin also called T3 and T4 hormones respectively) into the bloodstream and let them go to the body's cells. Every enzymatic process in the production and secretion of thyroid hormones is controlled by Thyroid stimulating hormone (TSH). All people worldwide are susceptible to thyroid disease, which is often accompanied by hyperthyroidism and hypothyroidism. The thyroid's structural proximity to the upper airways, a main route for coronavirus entry, holds up the idea that the thyroid gland might be a target for Covid-19 or SARS-CoronaVirus-2. When the thyroid gland makes and secretes too much thyroid hormone, it is referred to as hyperthyroidism and if the patients do not take any precautions, hyperthyroidism may lead to cardiac hypertrophy. The Covid-19 epidemic had a substantial influence on our daily lives and has unexpectedly changed the way of medical research. This review aimed to discuss the effects of SARS-CoronaVirus-2 on the Thyroid Gland in the Context of Hyperthyroidism and related causing diseases, highlighting the common causing diseases of hyperthyroidism along with their treatments. We also highlight the impact of SARS-CoronaVirus-2 and its mRNA immunization. So that future studies should focus on the number of important advances and improved drug management in the treatment of Thyroid relating diseases, which may or may not be triggered by the coronavirus and its immunization.
Exploring Cloud Computing Adoption in Higher Educational Environment: An Extension of the Tpb Model With Trust, Peer Influences, Perceived Usefulness and Ease of Use

Cloud computing is regarded as the next generation of computing. It is progressively being used as a launching pad for digital innovation and organizational agility. Cloud computing is frequently used by private and public organizations due to its flexibility, collaboration, cost-effectiveness, and scalability. These characteristics make cloud computing indispensable for individuals and businesses such as higher education institutes. Several prior studies covered the technological facets of cloud-based contexts, including cloud security, scalability, and virtualization. However, it is contend that the main barrier to cloud computing isn't technical but cognitive or behavioural, and in particular attitudinal. Thus, this research aims to study higher education’ students’ attitudes and their intention to adopt cloud computing, with a specific concentration on the effect of trust, peer influences, perceived usefulness and ease of use in order to investigate the factors influencing the adoption of cloud computing in higher educational environment in Saudi Arabia. This study presents an extended Decomposed Theory of Planned Behaviour (DTPB) to include trust, peer influences, perceived usefulness and ease of use as a cognition, representing a person’s perception of social influence to perform or not perform a behaviour under consideration. The proposed model was able to explain 62% of the variance in behavioural intention and 65% of students' attitudes towards the adoption of cloud computing in higher educational environment. The study's findings show that the proposed model explained a significant amount of variation in cloud computing adoption. It suggests that the model expansion by incorporating trust, peer influences, perceived usefulness and ease of use factors were valuable explorations. Further, the findings demonstrate that university students' attitudes toward using cloud computing are significantly influenced by perceived ease of use, trust in cloud computing service provider and perceived usefulness, which have the ability to explain their attitude by 22.15%, 21.9% and 20.9% respectively. The result also shows that "subjective norm" alone explains 33.95% of students' "behavioural intentions" towards using cloud computing, followed by their "attitude," which explains around 14.24% of "behavioural intentions," and then university students’ "self-efficacy," with 13.71%.
Optimizing Bank Marketing Strategies Through Analysis Using Lightgbm

Marketing campaigns in a bank are one of the ways for the bank to achieve its organizational goals. Optimal marketing is a crucial factor for a bank's success in attracting and retaining customers. Therefore, if a bank's marketing campaigns are carried out suboptimally, it will be challenging to achieve the goals of those campaigns. In this case study, it can be observed that the number of customers who subscribe to fixed-term deposits is lower, with a proportion of 5289 customers making deposits and 5873 customers not making deposits. This research aims to optimize bank marketing strategies by applying analysis using the LightGBM algorithm, which is a highly effective and efficient Gradient Boosting Decision Tree algorithm. This approach facilitates the design of more optimal marketing strategies. The accuracy score of the predictive model generated is 0.8584, with an F1 score of 0.8564, including 974 true negatives and 943 true positives.
Histological Study of Alteration in Testes and Epididymis of Domestic Rabbits Caused by Tribulus Terrestris and Vitamin E.

Tribulus Terrestris (TT) is a common herbal plant with different categories that grows in many countries of the world. Traditional Chinese and Indian therapies have used TT for infertility treatment and also as a powerful antioxidant agent. Therefore, this study aimed to use this plant supplemented with vitamin E to study their combined effects on the histological condition of the testicle and epididymis of rabbits. This study was performed on 28 healthy male rabbits (445-950 g, 2.0-3.0 months old) that were randomly divided into four groups (n=7). All animals were subjected to clinical examination to ensure that they were free of external and internal parasites with the use of some preventive treatments. The animals were housed individually (cage size: 50 cm×50 cm×40 cm) over the 60-day study period starting from January 2022, with an adaptation period of two weeks. Tribulus Terrestris and vitamin E treatments were as follows: the first group (G1) was daily fed on a standard diet and kept as the control group, the second group (G2) was daily fed on the same ration plus 1 g of TT (animal/daily), the third group (G3) was daily fed on the same ration plus 1 g of TT supplemented with 60 mg of vitamin E (orally) (animal /daily), and the fourth group (G4) was daily fed on the same ration, with the addition of 60 mg vitamin E per animal (orally). The morphometric investigation, macroscopic variables (including body weight, testicular weight, and volume), and the microscopic parameters of the testicular seminal tubule were measured. The histological section showed the absence of negative effects after the oral administration of TT at a dose of 1 g per day and 60 IU vitamin E for each animal. However, there was a positive effect on spermatogonia and spermatocytes in all animals, while the spermatogonia in the experimental groups were more dense, especially in the second and third groups, compared to the control group. The seminiferous tubules were significantly lined with spermatogonia, spermatocytes, and round spermatids (P<0.5) in the experimental groups, compared to the control group. Nevertheless, the epididymis tissue did not show traces of histological changes, such as epididymal hyperplasia. Sperms were more frequent in the lumens of the epididymis as well as the lumens larger than those of the control. Based on the results of this study, it can be concluded that the pole plant and vitamin E have a positive effect on the epithelial lining of the seminiferous tubules and the epididymis with an increase in sperm formation and differentiation towards maturity.
