Prevalence and Pattern of COVID-19 among Healthcare Workers in Rivers State Nigeria

Introduction: The evaluation of COVID-19 prevalence among healthcare workers (HCW) within the general population of COVID-19 cases is an important epidemiologic variable. The objective of this study is to describe the prevalence and patterns of COVID-19 infection in HCWs amongst a group of patients receiving care for COVID-19 in Rivers state, Nigeria. Methods: This study was a prospective descriptive study of all consenting patients who received care through hospitals, designated for COVID-19 treatment in Rivers state either as in-patient or out-patient following a laboratory-confirmed diagnosis of COVID-19 based on a positive SARS-CoV-2 RT-PCR from April to September 2020. Results: A total number of 646 COVID-19 patients were enrolled over the study period with 98 (15.2%) HCWs in the patient population. The HCWs with COVID-19 consisted largely of Doctors 47 (47.9%), Nurses 30 (30.6%), and socio-sanitary and hygiene workers 10 (10.2%). There were 46 (46.9%) female HCWs, compared to Non-HCWs with 112 (21.1%), females, p = 0.000. Sixty-eight (69.4%) HCWs had a source of contact for infection established compared to Non-HCWs with an established source of contact in 181 (34.2%), p = 0.000. Eight (8.2%) HCWs had Severe disease compared to 52 (9.8%) Non-HCWs with severe disease, p = 0.670. The case fatality in HCWs was 1% compared to 1.9% in Non-HCWs, p = 0.554. Conclusion: The prevalence of COVID-19 among HCWs in the study location is high with clinical and clinical support staff particularly, doctors and nurses are at higher risk of COVID-19 infection. This calls for action to improve and prevent HCWs infections in hospital settings in addition to improving HCW infection prevention behaviour in the community. The intensification of risk communication, provision of protective equipment (PPE), and training on the appropriate use of PPE; in addition to routine surveillance for infection is recommended.
Online reinforcement learning for fixed-wing aircraft longitudinal control

Reinforcement learning is used as a type of adaptive ﬂight control. Adaptive Critic Design (ACD) is a popular approach for online reinforcement learning control due to its explicit generalization of the policy evaluation and the policy improvement elements. A variant of ACD, Incremental Dual Heuristic Programming (IDHP) has previously been developed that allows fully online adaptive control by online identiﬁcation of system and control matrices. Previous implementation attempts to a high ﬁdelity Cessna Citation model have shown accurate simultaneous altitude and roll angle reference tracking results with outer loop PID and inner loop IDHP rate controllers after an online training phase. This paper presents an implementation attempt to achieve full IDHP altitude control under the inﬂuence of measurement noise and atmospheric gusts. Two IDHP controller designs are proposed with and without the cascaded actor structure. Simulation results with measurement noise indicate that the IDHP controller design without the cascaded actor structure can achieve high success ratios. It is demonstrated that IDHP altitude control under measurement noise and atmospheric gusts are achievable under four ﬂight conditions
Physicochemical and Nutritional Characterization of Starch Isolated from Colocasia antiquorum Cultivated in Oaxaca, Mexico

The physicochemical and nutritional characteristics of Colocasia antiquorum (taro coconut or Chinese taro) starch cultivated in Oaxaca, Mexico, were determined. The granules of Colocasia antiquorum presented a truncated ellipsoidal shape. The chemical composition analysis showed levels of moisture, ash, protein, fat, fiber, and NFE in a dry base of 10.29, 0.18, 2.0, 0.05, 0.01, and 97.76, respectively, as well as amylose and amylopectin contents of 13.05 and 86.95%, respectively. Gelatinization temperatures, onset (), peak (), and final (), were 72.86, 82.91, and 93.05°C, respectively. Solubility, swelling power (SP), and water absorption capacity (WAC) correlate directly with increments in temperature. Transmittance value (% T) for taro coconut was 0.3% and its apparent viscosity ranged from 100 to 150 cp. The nutritional characterization of Colocasia antiquorum’s starch amounted to 97.88% of total starch (TS), while available (AS) and resistant starch (RS) were 93.47 and 3.70%, respectively. Colocasia antiquorum, grown in Oaxaca, Mexico, is an unconventional source of starch with added value due to its potential use as an ingredient in the development of new products or as a substitute for conventional starch sources in industrial processes.
How is science clicked on Twitter? Click metrics for Bitly short links to scientific publications

To provide some context for the potential engagement behavior of Twitter users around science, this article investigates how Bitly short links to scientific publications embedded in scholarly Twitter mentions are clicked on Twitter. Based on the click metrics of over 1.1 million Bitly short links referring to Web of Science (WoS) publications, our results show that around 49.5% of them were not clicked by Twitter users. For those Bitly short links with clicks from Twitter, the majority of their Twitter clicks accumulated within a short period of time after they were first tweeted. Bitly short links to the publications in the field of Social Sciences and Humanities tend to attract more clicks from Twitter over other subject fields. This article also assesses the extent to which Twitter clicks are correlated with some other impact indicators. Twitter clicks are weakly correlated with scholarly impact indicators (WoS citations and Mendeley readers), but moderately correlated to other Twitter engagement indicators (total retweets and total likes). In light of these results, we highlight the importance of paying more attention to the click metrics of URLs in scholarly Twitter mentions, to improve our understanding about the more effective dissemination and reception of science information on Twitter.
Phenotypic and Genotypic Analysis of the Antibiotic Resistance Profiles of Gram Negative Bacteria Isolated from the Blood Culture Samples

Sepsis is a common serious public health problem that may be fatal (1). Worldwide incidence studies have revealed an incidence of 300,000 cases per 100,000 population for the disease (2, 3). On the other hand, there is a consensus on the fact that its incidence increases due to the aging population with multiple infectious comorbidities, increasing use of immunosuppressive treatment, and high-risk interventions (4, 5). Assessment of antimicrobial susceptibility of pathogenic microorganisms as well as their rapid and accurate identification play a critical role in reducing the incidence of bloodstream infections (6, 7). Bacteria, such as Enterobacteriaceae family, Pseudomonas aeruginosa and Acinetobacter baumannii, cause serious bloodstream infections. Increased antibiotic resistance rates of these microorganisms create concerns with respect to public health (8, 9). Carbapenem resistance bacteria has emerged as an important public health problem due to high mortality, length of hospital stay and high hospital cost (10). Because it is seen that carbapenems are ineffective used in severe bacteremic infections caused by multi-resistant Gram-negative bacteria (11). The reason for the ineffectiveness of carbapenems is the hydrolysis enzymes (carbapenemase) of Gramnegative bacteria (12). The most widely known carbapenemase are classified as KPC (Ambler class A), NDM and VIM (Ambler class B; metallo-βlactamases, MBLs) and OXA-48 (Ambler class D) (12). OXA-48, was first described in a K. pneumoniae in Turkey (13). OXA-48 producing bacteria were reported from different parts of the world (14, 15). In addition, the imipenemase (IMP) enzyme encoded by the blaIMP gene was first described in the MBLs class in Japan (16). Later, it was detected less frequently in Enterobactericeae in England and Europe (17). ABSTRACT
Exploring the Linkage Between Financial Development and Economic Growth: the ARDL Bounds Testing approach

This study investigates the cointegration, short and long run dynamics and causal links between financial development and economic growth in Bangladesh for the period 1973 to 2015. We applied the Autoregressive Distributed Lag (ARDL) Bounds Testing approach and the Granger causality test. The ARDL bounds tests and other cross-checking test confirmed the long run cointegration between economic growth and financial development indicators in Bangladesh. The two financial development indicators, growth in broad money to gross domestic product (GDP) ratio and growth in total deposit liabilities to GDP ratio appeared to have time variant impact on economic growth: the former having significant positive impact in the short- run but negative impact in the long- run, while the latter has significant negative impact in the short- run but positive impact in the long- run. The Granger causality analysis indicated a bidirectional, co-evolutionary process between financial development and economic growth.
Attraction, Social Presence, Sociability, and Booking Intentions: The Moderating Role of Homophily

It is essential for hotel marketers to better understand how human images—found in website photographs—are perceived by customers, and how such perceptions can affect customers’ website experience and behavioral intentions. Given the lack of empirical studies related to the effects of human images and hotel website photographs, this study first assesses the influence of physical and social attraction evaluations—related to human images in hotel website photographs—on perceived social presence, in order to further examine the relationships between social presence, sociability, and booking intentions. Moreover, the moderating effects of background homophily, on the relationships between physical and social attraction and social presence, are also examined. This study, which adopts structural equation modeling and analyzes data collected from a sample of 417 U.S. travelers who have recently booked a hotel room directly through a hotel website, confirms all of the aforementioned relationships.
Galaxy Clusters Reconstruction

In the present work, we introduce a machine learning-based approach for galaxy clustering. It requires to determine clusters to provide further galaxies groups’ masses estimation. The knowledge of mass distribution is crucial in dark matter research and study of the large-scale structure of the Universe. State-of-the-art telescopes allow various spectroscopy range data accumulation that highlights the need for algorithms with a substantial generalization property. The data we deal with is a combination of more than twenty different catalogues. It is required to provide clustering of all combined galaxies. We produce a regression on the redshifts with the coefficient of determination R 2 equals 0.99992 on the validation dataset with training dataset for 3,154,894 of galaxies (0.0016 < z < 7.0519). The application of a modern hierarchical density clustering algorithm for the separation of the groups of the galaxies allows us to obtain a result that is consistent with the work [4].
Professionalization of Online Gaming? Theoretical and Empirical Analysis for a Monopoly-Holding Platform

We analyze the private equilibrium of a two-sided market representing the online gaming industry under a principal-agent model. A monopoly-holding platform hires a manager to attract new members from both sides of the market while considering uncertainty on the adhesion of viewers and online gamers. First, we mathematically demonstrate that increasing cross-group network externalities can decrease the platform’s profit, which contradicts a canonical result from the field of two-sided markets. Moreover, knowing that the intermediary’s goal is aligned with the private interest of online gamers, machine learning models empirically show that the main theoretical outcome is observed in reality due to the presence of heterogeneous indirect network effects in online gaming activities. Second, we conclude that social welfare can be either harmed or improved for increasing cross-group network externalities, which means that the professionalization of online gaming may or may not be legitimized depending on the value taken by exogenous parameters related to the platform’s uncertainty on the number of agents that get on board, risk aversion of viewers, and royalty rate applied to online gamers. Finally, a discussion based on 2020 facts is provided and several policy recommendations are formulated to ensure the persistence of best regulatory practices.
Social entrepreneurship and social innovation: looking inside the box and moving out of it

The impact of the global recession has served to increase the pressure on the management of nonprofit organizations (NPO). Executive leadership is an essential component of the success of these institutions. The aim of this paper is to survey the existing literature on social entrepreneurship and social innovation in the third sector (TS). For this, we used the collection of existing literature on the Web of Science (WoS). The 176 articles selected in this database were analyzed analytically and also using the VOSviewer software. The results show the existence of three approaches that highlight a relationship between entrepreneurial behavior and NPO performance, the creation of social value and the entrepreneurial orientation of NPO that triggered the emergence of hybrid organizations: social enterprises. This study aims to contribute to the construction of a holistic model for the sector.

Quantitative sperm characteristics of Tankwa goats with special reference to hyperactivated motility

Computer-assisted semen analysis (CASA) is an automated and objective method of evaluating structural (e.g. morphology) and functional sperm parameters (e.g. motility and hyperactivation). Sperm hyperactivation is essential for successful fertilization and is thus an important aspect in determining the fertility potential of a male. In the current study, CASA was used for standard semen analysis and for comparison of the ability of phosphate buffered saline (PBS), BO sperm wash (10 mM caffeine), 4% lignocaine, and 5 mM procaine hydrochloride to induce hyperactivation in Tankwa goat spermatozoa. Twenty-nine ejaculates were collected from randomly selected male goats by electroejaculation. Although none of the four media affected percentage total sperm motility, lignocaine caused a significant decrease (P >0.05) in percentage progressive motility. Exposure to procaine resulted in an increase in swimming speed (P ≤0.05) and star-spin motility tracks, which are typical of sperm hyperactivation. Using PBS and procaine motility data from individually selected spermatozoa, receiver operator characteristic curves were constructed to distinguish the kinematic parameters employed as cut-off values for sperm hyperactivation. PBS and BO sperm wash did not induce hyperactivation (0.1 + 0.2% and 0.04  0.2% respectively), while lignocaine induced little hyperactivation (3.4 + 3.0%) and procaine hydrochloride had the highest percentage hyperactivation (25.3 + 13.6%). The large variation in hyperactivation (0–54.5%) may reflect inter-individual differences in sperm quality among these males. This study indicated procaine hydrochloride was the most promising hyperactivation-inducing medium for Tankwa goat spermatozoa and should be considered for similar assessments in other animal species Keywords: computer-aided sperm analysis, procaine hydrochloride, sperm kinematics, sperm morphometry, sperm motility
Why Not Travel to Malaysia? Variations in Inbound Tourists’ Perceptions toward Halal-Friendly Destination Attributes

The importance of halal tourism has prompted countries and business operators to place more emphasis on this lucrative sector. The purpose of this study is to investigate the effects of halal-friendly destination attributes on inbound tourists’ behavioral intention in the context of Malaysia. Furthermore, a comparative analysis was conducted to investigate the similarities and differences between Chinese and Indonesian Muslim tourists. A total of 666 observations were collected using surveys and the data sets were analyzed via partial least squares structural equation modeling. The empirical results show that both countries have indicated variations in terms of preferences for social environment, services, and facilities. We contribute to the knowledge on the constitutive attributes of the halal-friendly destination, while providing theoretical explanations for the differences among Muslim tourists in the Asian markets. Finally, directions for future research are proposed.
Why are low-educated adults underrepresented in adult education? Studying the role of educational background in expressing learning needs and barriers

ABSTRACT The shift to a knowledge society has transformed the way we live and work, which is especially challenging to adults with low education levels. Adult education could be the answer, but low-educated adults participate least in adult education. The present study uses data from the Programme for the International Assessment of Adult Competencies to investigate participation needs and barriers of low-, medium- and high-educated adults across 15 European countries (N = 20,593). Descriptives show that low-educated adults report the lowest need for training to exercise their job and indicate to be the least prevented from taking more training because of experienced barriers. We then analysed which barriers non-participating and participating adults were referring to. While medium- and high-educated non-participants indicate being prevented because of work and family responsibilities, low-educated non-participants chose family responsibilities but mainly and remarkably the option ‘other’ as their most important barrier. Contrary to medium- and high-educated adults, low-educated adults’ most important barrier could not be defined. A possible explanation is that they experience more dispositional barriers (such as bad memories of education or low self-esteem), which were not included in the list. Our results point to the importance of targeting low-educated adults in participation research.
“I Have Been a Sojourner in a Foreign Land”: A Qualitative Inquiry on the Psychological Experiences of International Students Enrolled in a Christian University

International students make up 5.5% of all university students in the United States. In addition, international students consist of approximately 4% of the student population in Christian higher education. Although there is a significant number of international students enrolled in faith-based institutions, this population remains underrepresented in multicultural psychological literature. Thus, applying the intrapersonal-interpersonal-spiritual framework, we interviewed 15 international students from a Christian university to investigate their unique and shared experiences with the general international student population in the United States. The Consensual Qualitative Research method (CQR) was employed, and seven principal domains were identified: (a) religiousness, (b) reactions toward international students, (c) social support and acceptance, (d) hopes and expectations, (e) cultural adaptation, (f) cultural differences, and (g) international student identity. Similar themes to those present in the existing international student literature were established, but differential themes related to religiousness were discovered as well. Implications for Christian campuses are discussed.

Effect of localization criteria and yield criteria in predicting the forming limit diagram (FLD) of DP590 steel sheets

ABSTRACT The main objective of the present work is to study the effect of different localisation criteria and yield criteria in predicting the forming limit diagram (FLD) of dual phase (DP) 590 steel sheets. DP590 steel is used in automotive applications for structural and safety parts such as cross members, longitudinal beams, B-pillar reinforcements and bumper reinforcements. Limit dome height (LDH) tests were performed for DP590 steel sheets and experimental FLD is plotted. Tensile tests and plastic strain ratio ‘r’ tests were performed at different rolling directions to evaluate the mechanical properties The evaluated mechanical properties were used in finite element (FE) simulations to predict the FLD of DP590 steel sheet. Three material models namely Transversely anisotropic elastic plastic, 3 parameter Barlat yield law and Hill 3 R which includes diverse yield criteria Hill 48, Barlat 89 and Hill 3 R, respectively, were used in FE analysis. Three different localisation criteria namely equivalent plastic strain criterion, thickness criterion and localisation criterion based on true strain gradient were used to predict the FLD of DP590 steel sheets. It was found that predicted FLD is close to experimental FLD when localisation criterion proposed, based on true strain gradient and Hill 48 yield criterion is used.
The long-term effects of the Chinese great famine on mental health

ABSTRACT A growing body of studies examined the effects of health shocks during early childhood and in-utero in developing countries. However, the related research on mental health is limited. In this article, we contribute to the existing literature by providing evidence of the long-term effects of the Chinese Great Famine in 1959–1961 on self-reported mental health. Using CHARLS, we find that people who were exposed to the famine in early childhood are more likely to have mental problems. In addition, women are more likely to be impacted by the famine.
