Tourists’ water conservation behavior in hotels: the role of gender

Abstract Hotels and destination managers are increasingly expressing concern about the impacts of climate change and sustainable water use, especially in crowded and water-scarce destinations. The aim of this study is to examine gender differences in hotel guests’ reported water conservation behavior (WCB) when on vacation. The study examines several factors that can potentially affect these gender differences, namely attitudes toward water conservation, normative and hedonic motives, destination problem awareness, and destination attachment. Data from a sample of 680 hotel guests reveal significant gender differences, with specific factors affecting the WCB of guests of each gender. Attitudes exert a positive influence on guests’ WCB. This influence is greater for women than for men. Normative motives also positively influence attitudes, although this effect is greater for men than for women. Conversely, hedonic motives negatively influence water conservation attitudes, and this effect is greater for women than for men. Lastly, destination problem awareness positively influences normative motives, while destination attachment negatively influences hedonic motives. No gender effect is found for these relationships. The implications for research and practice in sustainable tourism and pro-environmental behavior are presented.
Effects of heavier live weight of ewe lambs at mating on fertility, lambing percentage, subsequent live weight and the performance of their progeny

ABSTRACT Ewe lamb live weight at first mating (7 months of age) is positively associated with reproductive performance and led to the recommendation of a minimum mating live weight of 40 kg. This experiment examined the effects of heavier mating live weight of ewe lambs on their live weight, fertility, lambing percentage and their progeny performance to weaning. Ewe lambs (n = 270) were randomly allocated to one of two treatments. The Heavy group (n = 135) was preferentially fed until mating, achieving 47.9 ± 0.36 kg, while the Control group (n = 135) had an average mating live weight of 44.9 ± 0.49 kg. Fertility, lambing percentage, ewe live weights, the survival and live weights of their progeny were recorded. There was a 28% increase in fertility and a 59% increase in lambing percentage in the Heavy group compared to the Control group. Progeny survival and live weights did not differ (P > .05) by treatment. A curvilinear relationship between fertility and ewe live weight at mating was identified, suggesting that ewe lambs should be mated at a live weight of 50–55 kg to maximise fertility and lambing percentage without reducing ewe live weight nor the progeny performance.
Soil persistence and environmental risk assessment of chlorpyrifos under different organic manuring in the tropical sugarcane ecosystem

ABSTRACT Chlorpyrifos has label claim against sugarcane termites and is applied as a soil drench at planting. The organic manures viz., composted coir pith, farmyard manure, press mud and sugarcane trash are also applied at the time of planting mainly to conserve the soil moisture in the tropical environment. The organic manures may have some impact on the persistence of chlorpyrifos in the soil. Hence, the persistence of chlorpyrifos in the manurial soils was studied by employing the single-step sample preparation method and GC-ECD. The initial deposits of chlorpyrifos were 0.325–0.383 µg/g across the treatments involved in the study. The residues were quantified up to 75 days after treatment (DAT) and were below 0.01 µg/g on 90th DAT. The soil half-lives of chlorpyrifos were in the range of 19.8–21.0 days in the manured soils as against 18.7 days in the control soil. Thus, the organic manures applied at planting did not play any significant role in influencing the persistence of chlorpyrifos in the sandy clay loam soil of tropical sugarcane ecosystem. Further, the chlorpyrifos residues were not detected in the sugarcane leaf and stalk, indicating that there was no significant uptake by the plant from the soil. The calculated risk quotient values indicated that the chlorpyrifos residues may pose an unacceptable risk to earthworms during the first week of its application and thereafter, there could be a moderate level of risk in the tropical sugarcane environment.
The Mediating Role of Medical Students’ Attitudes towards Distance Education in the Relationship between E-Learning Styles and Academic Achievements

The COVID-19 global outbreak is a growing concern for continuing medical education. The COVID-19 pandemic has led many medical education programs to be carried out online in the world. This research aims to examine the mediating effect of attitudes towards distance education in explaining the relationship between e-learning styles and academic achievements of students in medical education conducted online. The research was carried out on 148 students studying in a six-year medical program at a university. In the research, students completed the e-learning styles scale, attitude scale towards distance education, and online questionnaire include some demographic information via Moodle-based Learning Management System (LMS). In addition, end of year grade point averages of the students was also used within the scope of the research. In the research, the direct effect of e-learning styles on the grade point average and an indirect effect on attitude towards distance education were tested with the mediation model. It was determined that gender is not a significant variable on e-learning styles and attitudes towards distance education. It was observed that students with higher daily internet usage times had higher attitudes towards distance education. In the research, it was observed that the attitude towards distance education has a mediating effect on the relationship between e-learning style and academic success. It is important to consider e-learning styles and attitudes towards distance education to increase academic success in online medical courses and provide better learning outcomes.
Residual SARS-CoV-2 viral antigens detected in gastrointestinal and hepatic tissues from two recovered COVID-19 patients

Residual SARS-CoV-2 RNA has been detected in stool samples and gastrointestinal tissues during the convalescence phase of COVID-19 infection. This raises concern for persistence of SARS-CoV-2 virus particles and faecal-oral transmissibility in recovered COVID-19 patients. Using multiplex immunohistochemistry, we unexpectedly detected SARS-CoV-2 viral antigens in intestinal and liver tissues, in surgical samples obtained from two patients who recovered from COVID-19. We further validated the presence of virus by RT-PCR and flow cytometry to detect SARS-CoV-2-specific immunity in the tissues. These findings might have important implications in terms of disease management and public health policy regarding transmission of COVID-19 via faecal-oral and iatrogenic routes during the convalescence phase.
New Protocol to Improve the Antibacterial Activity of Platelet Rich Fibrin – In Vitro Study

Background: Plasma concentrate products have Rapidly developed during the last few years, and it had significantly affected regenerative medicine because of its specific features which enhance healing and reduce pain after surgeries. this research aims to create an antibiotic releasing biomaterial based on the PRF.Methods: In-Vitro experimental study was conducted, 12 Healthy volunteers were included, each donated (40 ml) of blood. Chukrun’s protocol was used to prepare PRF (3000 rpm, 10m) with additional modification. Bacterial colonies and Miller-Hinton medium was prepared. Two types of bacteria were used for the culturing and incubation (Staphylococcus aureus, Enterococcus faecalis). Three Pharmaceutical forms (PF) of the antibacterial agents (Lincomycin) were incorporated with the PRF. Results: pharmaceutical form had a significant difference on the antibacterial activity of the PRF (P=0.000), ampoule and solution forms had the highest levels of bacterial growth inhibiting, however, powder failed to inhibit bacterial growth. Moreover, no significant difference was noticed between using 0.5ml or 1ml dose of antibiotic (P=339). Conclusion: It is possible to incorporate antibiotic with the PRF, which will improve the antibacterial activity of PRF, creating an ARB that can be used locally adjacent to minor surgery.
Evaluation of the Perception of Stress in University Students: Implications for Symptoms and Health Complaints and Nutritional Habits

Health education is seen as highly difficult and challenging, due to the high level of stress observed in students. The precise assessment of perceived stress becomes important for understanding the students’ profile as well as their nutritional habits during the university period. The aim of the analysis described in this article is to assess the associations between mental health, self-reported symptoms/health complaints, and nutritional habits in health students. Our findings suggest using it in other contexts such as public universities and other university courses to assess students’ mental health status and food intake
Student recognition of interference and diffraction patterns: An eye-tracking study

Previous studies have demonstrated that students have difficulties in applying the wave model of light to explain single-slit diffraction and double-slit interference patterns. In this study, we investigated if students could recognize typical interference and diffraction patterns at all. Eye movements of high-school students were measured while they were identifying patterns produced by monochromatic light on a double slit, single slit, and diffraction grating, and by white light on a diffraction grating. Most students had difficulties with recognizing double-slit interference pattern and diffraction grating pattern of monochromatic light. Identification of the single-slit diffraction pattern was easier probably due to its distinguishable central maximum. The easiest task for students was recognizing the diffraction pattern of white light on an optical grating. Eye-tracking data suggested that even students who incorrectly answered this question were aware that the diffraction grating separates white light into colors. Additionally, eye tracking revealed that students who identified patterns correctly attended more the correct pattern than other options, thus corroborating previous findings. Overall, the results indicate that the recognition of interference and diffraction patterns is quite demanding for students, suggesting that more attention should be paid to observing and understanding basic wave optics phenomena.

Incidence of Endophthalmitis after Intravitreal Anti-Vascular Endothelial Growth Factor Injections in an Operating Room in China

Purpose To evaluate the rate of presumed endophthalmitis (EO) after intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections performed in an operating room (OR) under sterile conditions in mainland China. Methods Retrospective single-center study between September 2012 and December 2017 at Beijing Tongren Eye Center, Beijing, China. Intravitreal injection database was reviewed. All anti-VEGF injections were performed using a standardized sterile technique in an OR. Injection protocols included antibiotics for 3 days pre-injection, topical 5% povidone-iodine rinsing before the procedure, and post-injection antibiotics for 3 days. Results A total of 37,830 intravitreal injections were performed at Beijing Tongren Eye Center. Three cases were managed as presumed EO (0.0079%). Positive cultures were documented in 2 of 3 cases. EO incidence following ranibizumab and conbercept administration was 0.0088% (3 in 33,930) and 0% (0 in 3,900), respectively. No significant difference was detected between the two drugs (P = 0.745). Conclusions Very low EO rates were seen in mainland China using a standardized sterile technique in an OR. However, EO could not be completely avoided.

Classifying basin‐scale stratigraphic geometries from subsurface formation tops with machine learning

Presented here is a transfer‐learning model for classifying basin‐scale stratigraphic geometries from subsurface formation tops. Support vector, decision trees, random forests, AdaBoost and K‐nearest neighbour classification models are evaluated to support this challenge. Each model is trained on labelled synthetic stratigraphic geometry data generated in Python using observable geological principles and concepts. Accuracy is measured using a weighted Jaccard similarity coefficient score, and certainty of each prediction is quantified using margin sampling. The random forest classifier has the highest initial accuracy, and the optimal hyperparameters for the model that yield 88.4% accuracy and 72.8% mean certainty via five‐fold cross‐validation and active learning are documented on a real‐world subsurface dataset. The random forest classifier with optimised hyperparameters is then used to make predictions on the real‐world subsurface formation tops dataset. The dataset consists of formation tops for the Upper Cretaceous and Palaeocene strata of the Eastern Greater Green River Basin in south‐central Wyoming. Results from model predictions include an area of truncation in the Lance Formation across the basin, and an area of onlap and truncation on the nose of the Rock Springs Uplift that previous studies in the region corroborate. It is believed that this model is most useful for guided interpretation, and identifying regions that warrant further inquiry by domain experts.
Different Populations Agree on Which Moral Arguments Underlie Which Opinions

People often justify their moral opinions by referring to larger moral concerns (e. g., “It is unfair if homosexuals are not allowed to marry! ” vs. “Letting homosexuals marry is against our traditions! ”). Is there a general agreement about what concerns apply to different moral opinions? We used surveys in the United States and the United Kingdom to measure the perceived applicability of eight concerns (harm, violence, fairness, liberty, authority, ingroup, purity, and governmental overreach) to a wide range of moral opinions. Within countries, argument applicability scores were largely similar whether they were calculated among women or men, among young or old, among liberals or conservatives, or among people with or without higher education. Thus, the applicability of a given moral concern to a specific opinion can be viewed as an objective quality of the opinion, largely independent of the population in which it is measured. Finally, we used similar surveys in Israel and Brazil to establish that this independence of populations also extended to populations in different countries. However, the extent to which this holds across cultures beyond those included in the current study is still an open question.
Acute physiological and perceptual responses to moderate intensity cycling with different levels of blood flow restriction

The aim of this study was to compare: i) the physiological and perceptual responses of low-load exercise [(moderate intensity exercise (MI)] with different levels of blood flow restriction (BFR), and ii) MI with BFR on the bike with high intensity (HI) exercise without BFR. The protocol involved large muscle mass exercise at different levels of BFR, and this differentiates our study from others. Twenty-one moderately trained males (age: 24.6 ± 2.4 years; VO2peak: 47.2 ± 7.0 ml.kg-1.min-1, mean ± sd) performed one maximal graded exercise test and seven 5-min constant-load cycling bouts. Six bouts were at MI [40% peak power (Ppeak), 60%VO2peak], one without BFR and five with different levels of BFR (40%, 50%, 60%, 70%, 80% of estimated arterial occlusion pressure). The HI bout (70%Ppeak, 90%VO2peak) was without BFR. Oxygen uptake (VO2), heart rate (HR), blood lactate (BLa), rate of perceived exertion (RPE), and tissue oxygen saturation (TSI) were recorded. Regardless of pressure, HR, BLa and RPE during MI-BFR were higher compared to MI (p < 0.05, ES: moderate to very large), and TSI reduction was greater in MI-BFR than MI (p < 0.05, ES: moderate to large). The responses of VO2, HR, BLa, RPE and TSI induced by the different levels of BFR in MI-BFR were similar. Regardless of pressure, the responses of VO2, HR, BLa and RPE induced by MI-BFR were lower than HI (p < 0.05), except for TSI. TSI change was similar between MI-BFR and HI. It appears that BFR equal to 40% of arterial occlusion pressure is sufficient to reduce TSI when exercising with a large muscle mass.
Community knowledge, attitudes and behaviors in prevention of COVID-19 transmission: A systematic review

The research objective was to determine the community's knowledge, attitudes, and behavior in preventing the transmission of COVID-19 with a systematic review approach. The research method used the protocol preferred reporting items for systematic review and meta-analysis (PRISMA). The research variables were sociodemography, knowledge, attitudes, and behaviors to prevent COVID 19. The search process for articles was accessed on three electronic journal databases. The article inclusion criteria are quantitative research, primary data, and year of publication (January-July 2020), in English, open access; have gone through the peer review stage, and full-text articles. A descriptive analysis was carried out on each research variable. The results showed ten articles that fit the inclusion criteria, consisting of 100% sociodemographic variables, 90% knowledge, 90% attitude, and 80% behavior. The number of articles with significant research results on knowledge variables (covering aspects of disease recognition, modes of transmission, general symptoms, and methods of prevention) was 61.11% of articles. The number of significant articles on attitude variables (including self-isolation, use of masks, social distancing, COVID-19, and government) was 35.54%. The number of substantial articles on the variable of preventive behavior (including handwashing, social distancing, hand sanitizers, use of masks, and self-isolation) was 45%.
Worker’s Personal Exposure to PM0.1 and PM4 Titanium Dioxide Nanomaterials during Packaging

ABSTRACT For the appropriate hygienic management of workplaces where workers handled nano-TiO2 products, the status of the personal exposure of workers to respirable dust (PM4) and nanoparticles (PM0.1) was investigated. Using a cyclone sampler for PM4 and a personal sampler for PM0.1, PM4 and PM0.1 exposure levels were evaluated to discuss them in relation to worker’s duties. The number of particles of 0.01–10 µm was also monitored online in order to examine the short-term fluctuation in the concentration and size distribution of particles. The 8h-time-weighted average (TWA) and 95% upper limit for respirable dust exposure were below the occupational exposure limit specified by the Japan Society for Occupational Health and the recommended exposure limits for TWA by NIOSH. The action level was exceeded during the filling of a flexible container bag. More than 70% of particles in the breathing zone was coarse agglomerates of >1 µm, while it may be influenced by powder properties and the handling process as well as the management of local ventilation. The maximum PM0.1 concentration (31.3 µg m-3) occurred in a powder filling booth without air ventilation. The operation of a gasoline powered forklift temporarily increased the concentration of ultrafine particles. Most of TiO2 powder was suspended as micron-order agglomerates in the breathing zone. However, since PM0.1 exposure was much larger than those in outdoor environment particularly under insufficient cares to aerosolized powder and air ventilation, PM0.1 exposure should also be monitored.
Civil society mobilisation after Cyclone Tracy, Darwin 1974

ABSTRACT Major disasters challenge or exceed the capacity of the official emergency management sector to provide needed rescue services, support and relief. Emergency services in most jurisdictions do not have the surge capacity for unusual or extreme events without drawing on other jurisdictions or local people from outside the formal emergency management organisations. In such circumstances, those in the affected area need to organise themselves and make maximum use of local resources to cope with the immediate aftermath of impact. To find the required surge capacity, this suggests a whole of society response with the official system working with the capacities of people, commerce and organisations outside the emergency sector. An example is provided by the destruction of the northern Australian capital city of Darwin by Cyclone Tracy in December 1974. Informal volunteering and emergent leadership in Darwin and across Australia were critical to the immediate response and relief. Volunteering was widespread and worked well alongside official emergency management. With today’s information and communication technologies and a strong national resilience narrative, we would expect to do at least as well. However, governments now exercise much more control over civil society. We examine the implications for surge capacity and adaptability.
