Comparative study on the proximate analysis and nutritional composition of Musanga cercropioides and Maesobotyra barteri leaves

This study investigated the proximate, mineral, vitamins and amino acid compositions of Musanga cercropioides and Maesobotrya barteri leaves. Proximate analysis was done according to the AOAC methods; Atomic Absorption Spectroscopy (AAS) was used to determine the mineral content, while High Performance Liquid Chromatography and Gas Chromatography were used to determine the vitamins and amino acids contents respectively. The proximate composition of the dried leaf of M. cercropioides was; moisture (60.58 ± 0.43 %), crude protein (6.58 ± 0.4%), crude fibre (8.85 ± 0.05%), crude fat (7.0 ±1.0%), ash (4.75 ± 0.25%) and carbohydrate (12.26 ± 0.12%). On the other hand, that of M. barteri was; moisture (50.53 ± 0.08%), crude protein (9.63 ±0.88%), crude fibre (2.9 ± 0.3%), crude fat (14.0 ± 0.3%) ash (8.5 ± 0.5%) and carbohydrate (14.44 ± 1.6%). Elemental analyses showed that M. cercropioides had significantly higher (p<0.05) levels of the elements (Fe, Mn, Zn, P, Na, K, Ca, Mg, Cr) when compared to M. barteri. The leaf of M. cercropioides was significantly higher in vitamins A, E, B1, B2, B3, B6 and B12 (p<0.05) when compared to that of M. barteri. However, M. barteri leaf had higher vitamin C content than M. cercropioides . The amino acid analysis revealed that. M. cercropioides had significantly higher levels of leucine, methionine, threonine and serine (p < 0.05). M. barteri, on the other hand, was higher in histidine, lysine, alanine, phenylalanine and valine. This study suggests that these two plants can serve as a good source of nutraceutical.

Fraud risk and trust on the intention to buy of e-commerce

This study aims to analyze and obtain empirical evidence of deceptive behavior as a moderating variable of trust in purchasing through e-commerce purchase intentions. The data of this research were obtained from the results of collecting a questionnaire of 100 respondents who were consumers who had made transactions through e-commerce sites. Testing the hypothesis in this study using the measurement model (Outer Model) and structural models (Inner Model) with the application of Partial Least Square (PLS). The PLS program used is SmartPLS version 3.02. 8. The results of this study indicate that trust has a positive effect on purchase intentions. However, with deceptive behavior as moderation, deceptive behavior weakens the relationship between trust in purchasing through E-Commerce and purchase intention as a mediating variable. Purchase intention is proven to be a mediating variable that mediates trust in mentally buying. The government should be more assertive in handling cases of e-commerce crime that are rife to create security and comfort for e-commerce site users.
Role of Technology Readiness in Airline Passengers’ Perceptions of
Self-service Technology Quality

Self-service technology (SST) is more crucial now than before for the service delivery of airlines. Many airlines employ various types of SSTs so that passengers can perform certain services on their own. Although many passengers enjoy using the self-service option, some are not ready to adopt such a technology. This study aims to investigate how passengers possessing different characteristics perceive technology readiness (TR) and examine the influence of TR on perceived SST quality. Questionnaires were used to collect data from airports in Bangkok, Thailand. A total of 382 usable data were analysed using one-way ANOVA and multiple regression analysis. Results indicate significant differences in TR across age, education, occupation, income, types of SSTs and air travel frequency. This study also reveals that TR dimensions, namely, optimism, innovativeness, anxiety and insecurity, are important factors influencing airline passengers’ perceptions of SST quality.
Audit partner rotation, and its impact on audit quality: Evidence from India

Abstract Using multiple indicators of audit quality, the study examines the impact of audit partner rotation on audit quality in India based on 1,694 firm years for the period of 2011–2017 when the institutional set up for audit partner rotation was voluntary. The empirical results indicate that the audit partner rotation had no significant impact on audit quality as measured by discretionary accruals and going concern audit opinion. The study finds that other factors like loss year, size of the firm, value, leverage have a statistically significant impact on audit quality. The empirical results also indicate an inverse relationship between audit fees and audit partner rotation implying, price-cutting of the audit. The findings are important to regulators regarding the significance of audit partner rotation in enhancing audit quality.
Molecular Evolution of N-Containing Cyclic Compounds in the Parent Body of the Murchison Meteorite

Primitive meteorites contain various classes of organic compounds. Because the molecular distribution in these meteorites is not fully clarified, we do not yet understand the comprehensive formation mechanism(s) of extraterrestrial organic compounds. In this study, diverse and abundant alkylated homologues of N-containing cyclic compounds were identified in the methanol extract of the Murchison meteorite by electrospray ionization using high-performance liquid chromatography/ultrahigh-resolution mass spectrometry. More than 600 positive ions were assigned to CnHmN+ and CnHmN2+, in which saturated and unsaturated alkylated pyridines and alkylimidazoles are predominant. Both can be synthesized from aldehydes and ammonia through aldol condensation and imine formation under an alkaline environment. Further redox reactions could have proceeded to make these molecules evolve to various CHN compounds, including alkylpiperidines and pyridine carboxylic acids. This study indicates that aldol condensation and formo.
A Review on Accuracy of Doppler Ultrasound in Various Knee Joint Pathologies

Pain in the knee joint has become one of the most common pathologies that are affecting humans of all age groups in the modern world. Many of the arthropathies are resolved with supportive care and complete tests but some of the diseases require early diagnosis and prompt treatment to prevent any long time effects. Doppler ultrasonography has revolutionized our way of approaching these diseases. It has several advantages over other imaging techniques. It is noninvasive and there is no use of a contrast dye which permits us to use this technique even in those patients who are hyper allergic. There is no use of radiations in ultrasonography. It can detect various minor abnormalities like cartilage thinning, partial or complete tears, synovial joints, abnormalities in the bony structure, inflammation debris in the joint, hematoma, and any ligamentous injury. It also helps us in the localization of the injury which further assist us in several aspects, one of which being the administration of the drugs with the help of an injection at the most optimal site.
Crystal structure and optical properties of silver-doped copper nitride films (Cu3N:Ag) prepared by magnetron sputtering

Silver-doped copper nitride (Cu3N:Ag) films were prepared by using radio frequency and a direct current magnetron sputtering method. The effects of silver doping on the crystal structure, surface morphology, and optical properties of the films were investigated. Results demonstrated that Ag doping influences the preferred growth orientation of the films. With the increased Ag content, the films grow from the (1 0 0) crystal face to the (1 1 1) crystal face. Ag doping changes the lattice constant, grain size, and optical band gap of Cu3N:Ag films. Cu3N:Ag films achieve the most remarkable crystallinity at 0.23 at% of Ag with lattice constant and optical band gap of 0.381 88 nm and 1.30 eV, respectively. Moreover, the doped Ag atoms fill the hollows in the Cu3N lattice and consequently reach the high-energy defect level. These atoms also generate impurity compound centers at high-energy level, shorten the non-equilibrium carrier lifetime of the films, and weaken the electronic transportation of the films.
Conceptual foundations of entrepreneurial strategy: A systematic literature review

Objective: The objective of the article is to contribute to a greater and deeper understanding of the ES conceptualisation. The relevance of the topic of Entrepreneurial Strategy (ES) stems from growing interest of society in entrepreneurship, which has become extensively discussed although the concept of ES is still poorly understood. Research Design & Methods: A systematic literature review (SLR) referring to 427 articles from the Web of Science and Scopus databases was conducted. Findings: The results made it possible to identify five ES conceptual foundations: i) economic theory and entrepreneurship; ii) entrepreneurial strategies, concept – theory; iii) entrepreneurial strategies, framework – models; iv) entrepreneurial strategies, contexts – application; and v) entrepreneurial strategies, application metrics. Implications & Recommendations: This SLR can help to highlight the gap in theories on ES, its conceptualisation and the fundamentals found in the literature. A research agenda is suggested for each ES foundation identified. Contribution & Value Added: The study is innovative given there have been no other identified SLR studies on the ES concept. The study attempts to contribute towards the literature by offering a model of interactions of the ES foundations. Article type: theoretical article
GRAIN YIELD OF COFFEE PLANTS FERTILIZED WITH DIFFERENT DOSES OF 20-00-20 NPK FORMULATION UNDER RAINFED CONDITIONS

ABSTRACT Little is known about the management of high-yield clonal Coffea canephora in the Amazonian Region, mainly for nutritional aspects and cultivation system efficiency. This study aimed to evaluate the influence of different nitrogen and potassium fertilization rates on coffee grain yield and fertilizer use efficiency of C. canephora trees. An experiment was performed at an experimental field of the Embrapa Rondônia in Porto Velho (RO), Brazil. It was carried out in a split-plot scheme with six doses of 20-00-20 NPK formulation (0; 250; 500; 1,000; 2,000; and 3,000 kg ha-1) and three years of evaluation (2014, 2015, and 2016). An interaction between fertilizer dose and crop year was observed. Fertilizer doses showed an exponential behavior, with maximum yields of 51, 114, and 79 bags ha-1 at 3,000 kg ha-1 in the crop years of 2014, 2015, and 2016, respectively. Such a behavior impacted average and accumulated yields in the three harvest seasons. As for crop year effect within each fertilizer dose, the highest yield was reached in the second harvest after pruning for renewal of orthotropic stems. Moreover, fertilizer use efficiency by plants decreased exponentially, with the highest value at the lowest dose. Increasing doses of 20-00-20 formulation promoted an exponential increase in grain yield but decreased its use efficiency by C. canephora plants. This management also stimulated a strong biannual production.
Why a clear coating modifies halftone color prints

It can be easily observed that a white support printed with halftone ink layers changes color when coated with a clear layer. The color change can be explained by purely optical phenomena, for example the perception of a different amount of light scattered by the ink-matter interface if the observer is not too far from the specular direction. But color change can be also observed far from the specular direction, especially with halftone colors, where the support has not a homogeneous reflectance at the mesoscopic scale. This is due to subsurface optical phenomena investigated only recently in the case of uniformly colored support. In the present paper, thanks to an original optical model dedicated to halftone colors, we show that this subsurface phenomenon tends to increase the chance for light to meet several ink dots, therefore the chance to be absorbed.
Precedent-extrapolation estimate of the seismic hazard in the Sakhalin and the Southern Kurils region

The paper describes the algorithm and the results of the seismic hazard estimate in the Sakhalin and Southern Kurils region based on the data of the Japan Regional Catalogue (JMA). A nonlinear differential equation of the second order is used as a mathematical model, and algorithms for optimization and predictability estimation are presented by the author's solutions. The forecasting algorithm is based on the search for seismic activity zones in which the current activity trends correspond to foreshock sequences recorded before strong earthquakes (precedents) that have already occurred. The earthquake time is calculated with extrapolating the detected trends to the level of activity that occurred at the time of the precedent earthquake. By the example of precedent foreshock sequences in Japan, it is shown that the lead time of such a forecast reaches 10–15 years and its implementation is due to the preservation and stability of the identified trends. A map of potentially dangerous zones for Sakhalin and the Kuril Islands and some examples of calculating the time of strong earthquakes according to the JMA catalogue as of August 31, 2018 are presented. Action sequence in identifying the potentially dangerous trends in seismic activity and the specifics of possible use of the technique in the Sakhalin region are considered.
Code-switching in Classroom Communication: How is It Perceived and What are the Impacts?

Investigating code-switching in a classroom setting has got paid attention from the parts of the world (see e.g. Edstrom (2006) in the United States; Bunyi (1998) in Kenya; Canagarajah (1995) in Sri Lanka; Lin (1996) in Hong Kong; Liu et al. (2004) in Korea; Rubdy (2007) in Singapore; and Ariffin and Husin (2011) in Malaysia. It was even stated that switching from one language to another becomes a strategy of communication used by teachers in order to increase students’ inclusion and understanding in the learning process (Macaro, 2005; Arthur & Martin, 2006). The recent paper is then carried out to evaluate students’ attitudes towards code-switching in classroom communication. Involving 302 students of English Department at Universitas Pamulang, this study finds out how students perceive code-switching in classrooms, whether this switching practice affects students’ understanding about the courses, especially in linguistics and literature courses, and describe whether there is a correlation between the students’ linguistic competence and the code-switching practices. The data revealed that switching practices in classroom communication are common phenomena performed by lecturers, but these practices are perceived positively by most participants. Furthermore, the switching practices were considered advantageous since they are believed to provide some benefits, among others are to facilitate students’ understanding, to create a good atmosphere during the lectures, and to encourage students’ participation. In terms of the correlation between linguistic competence and code-switching practices, the data indicated that most participants admitted that code-switching utilized by lecturers was not affected by the lecturers’ linguistic competence in English, while the lecturers perceived that their switching practices were due to their consideration of students’ linguistic competence in English and/or that of the course or subject learning objectives. To sum up, there seemed no harm to practice code-switching in the classroom instruction and the necessity of acquiring knowledge is to be paid more attention as it was implied by the participants’ responses.
Health-related quality of life in sandwich generation Iranian women

A – Study design, B – Data Collection, C – Statistical Analysis, D – Data Interpretation, E – Manuscript Preparation, F – literature Search, G – Funds Collection Background. Women play an important role in family caregiving, but there is inconclusive information about the effect of caregiving on women’s quality of life. The contradictory effects of caregiving on the physical and emotional health of caregivers have been reported. Objectives. The main objective of this study was to investigate the relationship between health-related quality of life (HRQoL) and multi-generational caregiving. Material and methods. This is a case-control study conducted in Ahvaz, Iran, on 360 family caregiver women: 180 women as sandwich generation caregivers who cared for family members in addition to caring for their own children, at least 21 hours per week for 6 months; and 180 women in the control group who only cared for their own children. Health-related quality of life was compared in the two groups. The two groups were matched regarding age, the number of children and socio-economic status. Data was analyzed using the chi-square test and ANCOVA test. Results. There was no significant difference between the sandwich generation and control groups in terms of the total score of health--related quality of life and its eight domains, as well as the scores of physical and mental health component summaries. Conclusions. It may be suggested that HRQoL is not negatively affected by sandwich generation caregiving in Iranian women. Cultural and religious factors prevent significant negative effects on health-related quality of life.
The problems of forming a system of green areas as an ecological framework of a large city (on the example of Kyiv)

Each large city is characterized by its own unique model of spatial organization of green areas, which form the ecological framework of the city and act as a condition for its balanced ecological development. The article presents results of an analysis of the actual state and preconditions for the formation of a system of green areas of public use of a large city on the example of the city of Kyiv. The model of the ecological framework of Kyiv, in comparison with the models of other European cities, is characterized. The specificity of the spatial organization of the landscaping system is marked by the presence of a powerful water-green diameter in the central part of the city, formed by the valley of the Dnipro River with islands, and a developed peripheral-ring forest park belt. The central and middle densely developed area of the city suffers from a significant lack of green areas for public use. The article formulates urban planning problems completion of the formation of an integrated ecological network of Kyiv, and outlined areas for improving the city's landscaping system.
Short-Term Outcomes in Elderly Patients with SARS-CoV-2 Infections Discharged from Community Hospitals

Introduction: Clinical outcomes from very elderly hospitalised patients with SARS-COV-2 (Covid-19), are poor, with a reported in-patient mortality as high as 20%. Age, sex, comorbidities, ethnicity and deprivation have all been shown to correlate with worse outcomes in patients with Covid-19, however the outcomes of elderly hospitalised patients once discharged remains unknown. We looked at our cohort of very elderly patients treated within community hospital settings. Methods & Results: A retrospective case note analysis was undertaken within our 222 bedded community hospital structure during the first wave of the pandemic from April to August 2020. A total of 129 patients were treated during this period. The average age of the patients was 78.8 ± 2.7 years. In patient mortality was 11% (14 patients). 83% of patients were discharged from the hospitals. 27% were discharged to care home facilities. At 90 days, 83% of patients were still alive but a third of these patients were re-admitted into hospital with various different diagnoses. Conclusion: Elderly patients who survived Covid-19 infection and left hospital have a relatively high mortality rate in the short-term. Also connected with this is a high morbidity rate and therefore care must be directed within primary care to ensure that this group stay out of hospitals.
Mathematics Teaching Anxiety among College of Education Pre-service Teachers in Ghana: The Influence of Mathematics Achievement and Field Experiences

these courses,pre-service teachers have been taught how to differently and effectively teach mathematics and also the use of manipulative materials in the teaching of specific mathematical contents. With these preparatory arrangements, it could be hazarded that pre-service mathematics teachers are psychologically and emotionally prepared to take up teaching roles in the coming years. Nonetheless, one Abstract: This study sought to explore the influence of mathematics achievement and field experience on pre-service teachers’ anxiety towards the teaching of mathematics. Data was conveniently gathered from 119 pre-service mathematics teachers in a college of education in Ghana. The pre-service teachers were in two groups of mathematics major and mathematics minor. Using the English version of the Mathematics Teaching Anxiety Scale, we observed that the pre-service teachers’ anxiety towards mathematics teaching was generally moderate. Additionally, we observed that the pre-service teachers’ mathematics teaching anxiety was related to their content knowledge, self-efficacy, teaching processes, and assessment practices. Our analysis further revealed that the major and minor pre-service mathematics teachers were different in their mathematics teaching anxiety regarding their self-efficacy but indifferent in the other three models. More so, we observed that the effect of mathematics achievement and field experience was statistically significant in the pre-service teachers’ mathematics teaching anxiety regarding content knowledge. Nevertheless, mathematics achievement was the major predictor. Despite of the prevalence of mathematics teaching anxiety among the pre-service teachers, we are of the view that additional field experiences and subsequent mathematics pedagogic courses may help reduce the anxiety levels.
A Media-Guided Attentive Graphical Network for Personality Recognition Using Physiology

Physiological automatic personality recognition has been largely developed to model an individual’s personality trait from a variety of signals. However, few studies have tackled the problems of integration methodology from multiple observations into a single personality prediction. In this study, we focus on finding a novel learning architecture to model the personality trait under a Many-to-One scenario. We propose to integrate not only the information on the user but also consider the effect of the affective multimedia stimulus. Specifically, we present a novel Acoustic-Visual Guided Attentive Graph Convolutional Network for enhanced personality recognition. The emotional multimedia content guides the formation of the physiological responses into a graph-like structure to integrate latent inter-correlation among all responses toward affective multimedia. Then these graphs would be further processed by the Graph Convolutional Network (GCN) to jointly model instances and inter-correlation levels of the subject’s responses. We show that our model outperforms the current state of the art on two large public corpora for personality recognition. Further analysis reveals that there indeed exists a multimedia preference for inferring personality from physiology, and several frequency-domain descriptors in ECG and the tonic component in EDA are shown to be robust for automatic personality recognition.
