Circumstances of infection with HCV in selected Polish provinces
Authors: Sierpińska Lidia 
Published: June 2021

Introduction. In Poland, approximately 730,000 people are infected with hepatitis C virus (HCV), which is nearly 2% of the total population, and about 170 million worldwide - 3% of the global population. Approximately 70-80% people infected with hepatitis C virus develop chronic hepatitis. Knowledge of the circumstances associated with the risk of infection with HCV is very important in the prophylaxis of hepatitis C. Materials and Method. The study was conducted during August 2014 - May 2018 in a group of 220 patients infected with HCV by the method of a diagnostic survey, using an author-constructed questionnaire. Results. The majority of respondents (138; 62.7%) did not know the circumstances of infection with HCV, whereas more than 1/3 of them (82; 37.3%) had knowledge concerning their infection. The respondents reported that the infection could have been mainly associated with a surgical procedure, followed by blood transfusion. The remaining circumstances of infection were: dental treatment, childbirth, organ transplantation, dialysis, treatment in a conservative ward, occupational exposure, plasmapheresis, as well as tattoo and narcotic injection. Self-reported state of respondents’ knowledge concerning hepatitis C was mainly on the mean level (160; 72.7%). About ¾ of respondents (173; 78.6%) did not consider themselves to be disabled due to hepatitis C. Conclusions. Health education is recommended in the population of adults about the risk of contracting HCV in treatment facilities and other places, where there is the transmission of blood-borne infections, as well as concerning the essence of chronic hepatitis C.
Lights, bats, and buildings: investigating the factors influencing roosting sites and habitat use by bats in Grand Teton National Park
Authors: Cole Hunter J. , Toth Cory A. , Barber Jesse R. 
Published: June 2021

Free-flying bats are highly affected by artificial night lighting, causing individuals to either 1) gather in unnaturally high densities around the light sources to exploit insects, or 2) travel increased distances to avoid light exposure. Similarly, nocturnal insects are disproportionately attracted to night lighting, trapping them until they die of exhaustion. The advent of new lighting technology which may decrease the impacts of night lighting on bats and insects by primarily producing light at wavelengths these animals are not sensitive to (i.e. in the red portion of the spectrum) is promising, however no studies have shown this at a large scale, and not in North America. Similarly, many studies on the effects of lights on bats, in general, have been on European species, and thus our overall understanding of how North American species are affected is low. Grand Teton National Park, Wyoming, provides an excellent natural system to study the effects of lights on bat behavior, as well as to test possible mitigation methods, as the park supports a large community of over a dozen species, as well as sizeable human infrastructure that generates night light. From June through September, 2019, we undertook a large-scale, blocked experiment examining bat activity and space use in Colter Bay Village under both traditional street-lighting, as well as new “bat friendly” street lighting. Using both passive echolocation records and radiotelemetry, we collected data that will allow us to examine the ability of red LED streetlights to mitigate artificial light’s negative impacts on bats and insects.

Forecasting eco-evolutionary dynamics in the Northern Blue butterfly (2019 field season)
Authors: Gompert Zachariah , Lucas Lauren 
Published: June 2021

Natural selection can drive rapid evolutionary change, particularly in human-altered habitats. Rapid adaptation to global change requires standing genetic variation for ecologically important traits, but at present little is known about how much relevant genetic variation most populations possess. With this in mind, we began a long term study of genome-wide molecular evolution in a series of natural butterfly populations in the Greater Yellowstone Area in 2012 to quantify the contribution of environment-dependent natural selection to evolution in these butterfly populations, and determine whether selection varies enough across space and time to maintain variation that could facilitate adaptation to global change. In 2019, we visited 11 focal populations to collect samples for DNA and plant chemistry, estimate population sizes (mark-release-recapture methods), and survey arthropod communities at the sites. Our analyses are ongoing, and this is a preliminary report, but thus far we have found that census population sizes are much higher than contemporary effective population sizes (though these metrics are highly correlated), and that both are independent of genetic diversity levels. These results are consistent with the hypothesis that selection plays a central role in eco-evolutionary dynamics in this system.

Background
Active parent participation in neonatal care and collaboration between parents and professionals during infant hospitalization in the neonatal intensive care unit (NICU) is beneficial for infants and their parents. A tool is needed to support parents and to study the effects and implementation of parent-partnered models of neonatal care.

Methods
We developed and psychometrically evaluated a tool measuring active parent participation and collaboration in neonatal care within six domains: Daily Care, Medical Care, Acquiring Information, Parent Advocacy, Time Spent with Infant and Closeness and Comforting the Infant. Items were generated in focus group discussions and in-depth interviews with professionals and parents. The tool was completed at NICU-discharge by 306 parents (174 mothers and 132 fathers) of preterm infants. Subsequently, we studied structural validity with confirmatory factor analysis (CFA), construct validity, using the Average Variance Extracted and Heterotrait-Monotrait ratio of correlations, and hypothesis testing with correlations and univariate linear regression. For internal consistency we calculated composite reliability (CR). We performed multiple imputations by chained equations for missing data.

Results
A 31 item tool for parent participation and collaboration in neonatal care was developed. CFA revealed high factor loadings of items within each domain. Internal consistency was 0.558 to 0.938. Convergent validity and discriminant validity were strong. Higher scores correlated with less parent depressive symptoms (r = -0.141, 95%CI -0.240; -0.029, p = 0.0141), less impaired parent-infant bonding (r = -0.196, 95%CI -0.302; -0.056, p<0.0001), higher parent self-efficacy (r = 0.228, 95%CI 0.117; 0.332, p<0.0001), and higher parent satisfaction (r = 0.197, 95%CI 0.090; 0.308, p = 0.001). Parents in a family integrated care model had higher scores than in standard care (beta 6.020, 95%CI 4.144; 7.895, p<0.0001) and mothers scored higher than fathers (beta 2.103,95%CI 0.084; 4.121, p = 0.041).

Conclusion
The CO-PARTNER tool explicitly measures parents’ participation and collaboration with professionals in neonatal care incorporating their unique roles in care provision, leadership, and connection to their infant. The tool consists of 31 items within six domains with good face, content, construct and structural validity.
Enhancing Arab learners’ EFL Linguistic Accuracy through Technology Integration in an Omani Context
Authors: Jose Jayaron 
Published: June 2021

Integration of technology especially ICT (Information and Communication Technologies) has been inevitable in the field of ELT for over many decades across the globe in general, and Arab world and Sultanate of Oman in particular. In line with the increasing trend of technology use in ELT, the study was conducted to determine the effectiveness of technological integration in improving students’ linguistic accuracy in writing in EFL classrooms in Oman. The experimental study was administered for a period of one semester among 56 students (N=56) at University of Technology and Applied Sciences, Al Musanna (UTAS-A) in Oman by means of online blog and forum treatments. The students were divided in to two groups – blog group (N=28) and forum group (N=28). While the former engaged themselves in online Blog writing asynchronously, the latter involved in online forum writing (discussions) synchronously. The learners’ performance was assessed through a pre-test and a post-test; an interview was administered to gauge the qualitative aspect of the study; consequently, the quantitative and qualitative data was analysed statistically.
Therefore, study has concluded that EFL linguistic accuracy of students treated with online forum and blogs improved over time, and forum group demonstrated better performance than blog group.
Social Networking Among Japanese Elders

Published: June 2021

The purpose of this study is to identify some of the predictors of social network formation with a focus on everyday behaviors such as greeting neighbors, attitudes about elder care, civic involvement, and hobby or social group membership. Using data from the 2010 and 2012 waves of the Japanese General Social Survey, we found that factors in which individuals have more control over are associated with the formation of social networks whereas factors that individuals have little to no control over are less likely to affect network formation. Specifically, elderly individuals who greet their neighbors and those who view elder care as an individual’s or family’s responsibility are more likely to have larger social networks. Likewise, civic engagement and participation in neighborhood associations are also significantly associated with forming social networks. Surprisingly, our analysis revealed that participating in hobby groups, length of residency in a community, and other control variables such as gender, income, and education are not significantly associated with forming social networks. Our findings indicate that the key components to building strong social networks are found within mundane daily activities. We conclude with several suggestions for how the elderly and communities can build elders’ social networks and thereby improve well-being. The implications of this study include raising awareness among individuals to prepare for a better, well-connected life in old age as well as suggesting local government programs for elderly care to help build more effective programs. Counselors could use this information to encourage their elderly clients to build social networks by increasing daily social interactions with neighbors and obtaining the view of self-reliance on elder care responsibility. Future researchers should seek to integrate the elder’s medical information in analyses in order to consider a comprehensive plan for the elderly’s well-being.

Published: June 2021

AIM: The study sought to assess the practice, awareness, adherence, benefits and promotion of Recreational Health Activities by pregnant women attending ante natal care clinics in Etinan.
METHOD: The survey research design was adopted for the study. 180 pregnant women out of the 536 registered and undertaking antenatal care in Primary Health Centres were selected by stratified random sampling. Self-structured questionnaire validated by experts and subjected to a reliability test with a coefficient of .68 was used for data collection.
RESULTS: The study revealed that majority of pregnant women in Etinan were not practicing recreational health activities though they expressed awareness of the activities. They do not adherence to recommended activities by care givers and thus did not benefit from it.
CONCLUSION AND RECOMMENDTIONS: It was recommended that pregnant women should be encouraged to participate in regular recreational activities before, during and after delivery so that they can adhere during future pregnancy. Couple days’ should be incorporated into ante natal care programmes so husbands will have an opportunity of taking part in recreational health activities with their pregnant wives.

Strong quadratic acousto-optic coupling in 1D multilayer phoxonic crystal cavity
Authors: Jin Jun , Wang Xiaohong , Zhan Lamin , Hu Hongping 
Published: June 2021

Abstract
Four methods are applied to calculate the acousto-optic (AO) coupling in one-dimensional (1D) phoxonic crystal (PXC) cavity: transfer matrix method (TMM), finite element method (FEM), perturbation theory, and Born approximation. Two types of mechanisms, the photoelastic effect (PE) and the moving interface effect (MI), are investigated. Whether the AO coupling belongs to linear or quadratic, the results obtained by the perturbation theory are in good agreement with the numerical results. We show that the combination method of FEM and perturbation theory has some advantages over Born approximation. The dependence of linear and quadratic couplings on the symmetry of acoustic and optical modes has been discussed in detail. The linear coupling will vanish if the defect acoustic mode is even symmetry, but the quadratic effect may be enhanced. Based on second-order perturbation theory, the contribution of each optical eigenfrequency to quadratic coupling is clarified. Finally, the quadratic coupling is greatly enhanced by tuning the thickness of the defect layer, which is an order of magnitude larger than that of normal defect thickness. The enhancement mechanism of quadratic coupling is illustrated. The symmetry of the acoustic defect mode is transformed from odd to even, and two optical defect modes are modulated to be quasi-degenerated modes. This study opens up a possibility to achieve tunable phoxonic crystals on the basis of nonlinear AO effects.

Abstract
Han, J, Liu, M, Shi, J, and Li, Y. Construction of a machine learning model to estimate physiological variables of speed skating athletes under hypoxic training conditions. J Strength Cond Res 37(7): 1543–1550, 2023—Monitoring changes in athletes' physiological variables is essential to create a safe and effective hypoxic training plan for speed skating athletes. This research aims to develop a machine learning estimation model to estimate physiological variables of athletes under hypoxic training conditions based on their physiological measurements collected at sea level. The research team recruited 64 professional speed skating athletes to participate in a 10-week training program, including 3 weeks of sea-level training, followed by 4 weeks of hypoxic training and then a 3-week sea-level recovery period. We measured several physiological variables that could reflect the athletes' oxygen transport capacity in the first 7 weeks, including red blood cell (RBC) count and hemoglobin (Hb) concentration. The physiological variables were measured once a week and then modeled as a mathematical model to estimate measurements' changes using the maximum likelihood method. The mathematical model was then used to construct a machine learning model. Furthermore, the original data (measured once per week) were used to construct a polynomial model using curve fitting. We calculated and compared the mean absolute error between estimated values of the 2 models and measured values. Our results show that the machine learning model estimated RBC count and Hb concentration accurately. The errors of the estimated values were within 5% of the measured values. Compared with the curve fitting polynomial model, the accuracy of the machine learning model in estimating hypoxic training's physiological variables is higher. This study successfully constructed a machine learning model that used physiological variables measured at the sea level to estimate the physiological variables during hypoxic training.
