Tillage, fertilizer type, and plant residue input impacts on soil carbon sequestration rates on a Japanese Andosol

ABSTRACT To identify efficient field management practices for enhanced soil carbon sequestration suited to crop rotation-based Andosol fields in northern Japan, the impacts of a combination of tillage, fertilizer type, and plant residue input on soil carbon sequestration rates were studied in a 4-year field experiment (April 2007 to March 2011). The rates of changes in soil organic carbon over the entire study period were determined by soil carbon stock change and by net ecosystem carbon budget. Across eight field management treatments and two replicates for each treatment, the rates of changes in soil organic carbon determined by net ecosystem carbon budget were positively correlated with the rates determined by soil carbon stock change (r = 0.766, n = 16). The arithmetic means of the rates determined by net ecosystem carbon budget (1.24 Mg C ha−1 year−1) were greater than those determined by soil carbon stock change (−0.18 Mg C ha−1 year−1) because decomposing crop residues and composted cattle manure in soil were included in the calculation of the net ecosystem carbon budget but were excluded in the calculation of soil carbon stock change (decomposing crop residues and composted cattle manure in soil samples were removed by sieving in measuring the soil carbon stock change). Both methods led to the same conclusion that soil carbon sequestration was significantly enhanced by composted cattle manure application and increased input of plant carbon from crop residues and green manure but was not enhanced by reduced tillage. The p values for net ecosystem carbon budget were smaller than those for soil carbon stock change in analysis of variance; therefore, the net ecosystem carbon budget was more sensitive to field management practice than the soil carbon stock change.
The Effect of Health Expenditure and Immunisation on Under-Five Mortality Rate in Selected African Countries.

Background: As a way of tackling child mortality, many countries in the world depend on their respective health-care system. But governments of most countries in Africa are yet to provide robust funding of their health-care systems as many people still depend on the out-of-pocket payment to receive health services. Against this backdrop, this study used annual panel data to assess the effect of health-care expenditure and immunisation on the under-five mortality rate in 30 selected African countries for the period 2000-2017. Methods: Multiple regression technique was adopted for the data analysis and the robust fixed regression estimator was preferred to the random effects as determined by Hausman test.Results: The findings indicated that domestic government general health expenditure had a significant negative effect on the under-five mortality rate. However, the effect of domestic private health expenditure on under-five mortality was not significant while external health expenditure had a significant negative effect on under-five mortality rate. The impact of diphtheria immunisation on under-five mortality was significant. Conclusions: Except domestic private health expenditure, government and external forms of health expenditure coupled with diphtheria immunisation were significant factors for the reduction of the under-five mortality in the selected countries.
High school students’ attitudes toward mathematics and its relation to mathematics learning achievement

Attitudes toward mathematics have been acknowledged among factors related to students’ mathematics learning achievement. The positive attitudes may de­crease when the education level getting higher. This study applied a mixed-method approach to describe students’ attitudes toward mathematics and to analyze the correlation between attitudes toward mathematics and mathematics learning achievement among students in the coastal area of Aceh Province, spe­cifically in Lhokseumawe City and North Aceh Regency. Total of 481 eleventh graders completed attitudes toward mathematics questionnaire online and 19 of them were involved in semi-structured interview. Data of mathematics learning achievement was obtained from students’ scores in their report card of the pre­vious semester. Data analyses were conducted by using Spearman’s correlation and chi-square test. The results of the study revealed that attitudes toward mathematics have a weak negative correlation but significant with mathematics learning achievement. This shows that there is a small percentage of students who have low learning achievement in mathematics tend to have a positive attitude towards mathematics in the high category, while students with high achievement on the contrary. Based on the results of the study, we provide seve­ral suggestions regarding learning mathematics and the direction of further research.
Etiology of cervicitis: Are there new agents in play?

Background: Considering the changing causative and resistance pattern of agents implicated in sexually transmitted infections (STIs), etiological diagnosis is imperative, especially in countries practicing syndromic management. This study was designed to identify etiological agents associated with cervicitis and to analyze their association with clinical and behavioral profile. Materials and Methods: Female STI clinic attendees presenting with cervico-vaginal discharge were examined for the presence of cervicitis. Endocervical swabs were collected for gram staining and real-time polymerase chain reaction was performed for various bacterial and viral STI agents in patients presenting with cervical discharge. A vaginal swab was also evaluated for bacterial vaginosis by Nugent's criteria. Results: Of 64 patients with vaginal discharge, 26.6% and 12.5% patients complained of genital itching and lower abdominal pain, respectively. Mean of 36.6 pus cells/hpf were observed, appreciably greater number in patients with Neisseria gonorrhoeae and Chlamydia trachomatis infections (P = 0.0063 and 0.0032, respectively). Pus cells were high (mean 68 pus cells/hpf) in patients with Ureaplasma urealyticum, though this may be attributed to coexisting N. gonorrhoeae. Agents isolated from endocervix were N. gonorrhoeae, 17 (26.6%), Trichomonas vaginalis, 4 (6.3%), HSV1 and C. trachomatis, 1 each (1.6%), HSV2, 9 (14.1%), U. urealyticum 5 (7.8%), Ureaplasma parvum 26 (40.6%), Mycoplasma genitalium (0%), and Mycoplasma hominis 11 (17.2%). Bacterial vaginosis was diagnosed in 14 (21.9%) patients. Multiple agents were isolated in 10 (two), 6 (three), 6 (four), and 1 (five) patients. Isolation of M. hominis and U. parvum was significantly associated with bacterial vaginosis (P = 0.04 and 0.003, respectively). Nonusage of condoms and mental stress predisposed to cervicitis. Conclusion: We concluded that there are changing etiological patterns of cervicitis. There is need to use tests that detect wider array of organisms, and can replace standard culture methods with molecular assays ,to increase the ability to diagnose more number of organisms implicated in cervicitis.

A parametric study wasinvestigated in order to show the effect of slots variation and to obtain the desiredfunctional characteristics. Experimental results show a good agreement withresults obtained by simulations. A satisfactorily omnidirectional for the radiationpatterns across the antenna operation bands was obtained.
Investigating key funds characteristics influencing their investment performance in Saudi Arabia: A dynamic panel data approach

The study examines if specific characteristics of funds influence the performance of Saudi equity mutual funds. Previous research has explored various aspects of mutual funds. However, the Saudi Arabia literature focuses on evaluating the funds’ performance. Hence, this study seeks to close this gap by providing a framework to explain the equity fund performance. Several risks adjusted performance measures are applied such as Jensen’s alpha, lower partial moment alpha, Sharpe ratio, LPM-Sharpe ratio using the dynamic panel specification over the period 2010–2019. Based on the LPM alpha, the risk-adjusted return analysis reveals that the Saudi equity funds outperformed their benchmark over the full sample period. The empirical results show that major fund-specific characteristics such as fund size, past performance, and flow explain future performance. Besides, the evidence confirms that Saudi funds benefit from the economies of scale and expertise, while funds requiring higher levels of initial investment tend to exhibit lower performance levels. These findings provide investors and fund managers with useful information to make the optimal investment decisions in the mutual fund industry.
Managing Tertiary Education for Peace and Conflict Resolution in Nigeria

Peace is a necessary condition for the sustainable development of any nation. It is described as the absence of physical and structural violence, and the presence of justice. Peace education involves human rights and conflict resolution education. This justifies the prominence of peace and conflict resolution education in the educational agenda of nations. Based on this, the paper examines the management of tertiary education for peace and conflict resolution in Nigeria. The population of the study comprised lecturers from the Faculty of Social and Management Sciences from the Universities of Benin, Port Harcourt, Calabar and Uyo, totalling 2312. A sample of 231 lecturers was drawn for the study using the Cluster Sampling Technique. One research question and one null hypothesis were considered in this study. Data collection was done using a structured instrument tagged, "Managing Tertiary Education for Peace and Conflict Resolution" (MTEPCR) Questionnaire. The Instrument was duly validated and tested for reliability using the Cronbach Alpha reliability formula. This gave a reliability coefficient of 0.81. Descriptive statistics such as mean, standard deviation, and simple percentage were used to answer the research question. The null hypothesis was tested at 0.05 alpha level, the one-way ANOVA. The result of the study indicated a low extent in the implementation of peace and conflict resolution education in tertiary institutions. There was no substantial difference in the implementation of peace and conflict resolution education among four federal universities. Based on these findings, key policy, practice and research implications are discussed.
First SARS-CoV-2 Infection in Patients with Severe Asthma Receiving Mepolizumab

Severe acute respiratory syndrome coronavirus (SARSCoV)-2 is a zoonotic viral pathogen belonging to the same family as SARS-CoV. To the best of our knowledge, no case that was receiving mepolizumab for severe asthma and that developed COVID-19 has been reported to date in literature. In September 2020, a 61-year-old male patient undergoing monthly mepolizumab treatment for the last 6 months, in addition to his current asthma treatment, was admitted to our clinic with complaints of high fever (38- 38.5°C), loss of senses of taste for 3-4 days, as well as nonproductive cough and shortness of breath. Patchy ground-glass densities were observed in basal parts of lower lobes of both lungs, and the patient recorded a positive nasopharyngeal real-time PCR SARS-CoV-2 test. The patient was initiated on hydroxychloroquine, favipiravir and an anticoagulant, and home quarantine was recommended. The patient's complaints had relieved significantly by day 5 of the treatment. There is a need for larger and more extensive studies on the effect of medications used for the treatment of patients with severe asthma on COVID-19 infection, and due to its antiviral effects, the potential favorable contribution of mepolizumab to the treatment of COVID-19 infection in this patient group should be monitored.

Modeling the Factors affecting Online Purchase Intention: The Mediating Effect of Consumer’s Attitude towards User- Generated Content

ABSTRACT User-Generated Content (UGC) has overshadowed other marketing trends and is a version of social proof. Current customer showcases their real-life experience and motivates potential customers to try these products and services. Building trust, creating community, customer engagement, loyalty, and social amplification are the denouements of UGC. This research investigates the impact of Brand Engagement (BE), Perceived Credibility (PC), Perceived Benefit (PB), and Information Quality (IQ) on attitude towards User-Generated Content (UGC). Also, how a consumer’s purchase intention is impacted by a consumer’s attitude towards UGC. The mediating effect of consumer’s attitudes towards UGC was also examined by this study. A sample of 260 consumers was collected in a structured survey for the analysis of data. To examine the hypothesized linkages between the mentioned variables, structural equation modeling was used. It was found that BE, PC, PB, and IQ have a positive effect on consumers’ attitudes towards UGC. Also, it was found that the consumer’s attitude towards UGC positively affected online purchase intentions. The Bootstrapping procedure shows that consumers’ attitude towards UGC possesses significant influence as a mediator between BE, PC, PB, IQ, and PI. The findings of this study can be useful for managers and marketers to enhance their understanding of the new marketing communication strategies.
