Pedestrian Crossing

Abstract In general, pedestrians want to cross a road at a mid-block section instead of intersections because it is the shortest route. According to an Indian scenario, most of the crosswalks in urban areas are not signalised and controlled. In this study, the crossing behaviour of pedestrians in terms of speed at a midblock section was studied by considering several parameters. Statistical tests such as ANOVA and Pearson correlation tests were performed in order to know the effect of parameters on the crossing speed of a pedestrian. The pedestrian’s age and gender, crossing type, pattern, time, number of stops, number of two wheelers, three wheelers, light and heavy commercial vehicles, and groups significantly affect their crossing speed. A multiple linear regression model was developed by considering the most significant parameters. The mean absolute percentage error, root mean square error, and R2 values were calculated to validate the models.

The Impact

Insofar as race, class, and gender have profound effects on people’s environmental experiences, and consequently their activism, the environmental field needs more work on the environmental experiences and insights of groups whose voices have been missing, including youth of color who live in urban areas in the U.S. In this paper, we focus on African American and Latinx students engaged in environmental projects in their urban communities and the impact of such projects on promoting pro-environmental leadership, agency, and behavior. We draw from written reflections and focus group interviews of several hundred 4th–12th graders (majority middle- and high-school students) who participated in place-based civic science projects. Thematic analyses of student responses found that students engaged in work on local environmental issues cultivated an appreciation for the natural world and an understanding of human-nature interdependence and the ties between the local environment and their communities’ health. Through taking action with others in their communities, students viewed themselves as contributors to their communities and started to form environmental identities in ways that are not traditionally measured. Findings point to the need for forms of environmental education that are contextually grounded and centered on environmental justice in urban areas.

And Function

Fatigue after myocardial infarction (MI) is a barrier to secondary prevention behaviors such as engaging in recommended levels of physical activity. However, little is known about physiologic factors that may contribute to fatigue. The purpose of this study was to describe the prevalence of fatigue in older adults after MI and to examine the associations of physiological factors of cardiac function (b-natriuretic peptide [BNP], mean arterial pressure, heart rate), inflammation (IL-6), BMI, and hemoglobin (Hgb) with self-reported fatigue. Methods: A convenience sample of women ( n =49) and men ( n =49) ages ≤65 completed questionnaires and underwent physiologic measures 6 – 8 months after discharge post MI. Subjects completed a demographic health form and fatigue measures (Revised Piper Fatigue Scale and the Multidimensional Assessment of Fatigue Scale functional items), and had height, weight, pulse, and blood pressure measured. Fatigue was measured as a total score (range 0 –310) and as 5 subscales (behavior/severity, affective, sensory, cognitive/mood, and function). Blood samples were also taken, and Hgb, IL-6, and BNP were measured in the same laboratory using standardized procedures. Results: Patients were an average of 75.69 ± 6.45 years of age. Fatigue was reported by 75 (77%) with a mean score of 102.46 (SD=57.7; range 8 –235). More women (84%) reported fatigue than men (69%), though this difference was not statistically significant. Patients reported higher fatigue scores on the behavior/severity and sensory subscales compared to the other fatigue subscales. Bivariate correlations of physiological factors and the total fatigue score revealed one significant physiological correlate, IL-6 ( r =.29). Controlling for age and gender, a multiple linear regression model explained 8.7% of the variance in fatigue ( F = 2.769 ; p <.05) with IL-6 as the only significant independent variable ( p =.010). An unexpected finding was that BNP did not correlate with fatigue. Discussion: Fatigue is prevalent in the majority of older adults after MI. Results indicate that inflammation may play a stronger role in fatigue than other physiological factors. Further research is needed to examine how inflammation and other physiologic factors may influence fatigue post MI.

This study evaluated the social and ecological factors that affect entomophagy in Ghana with a view to instigate the initiation of programmes for the use of insects for human and poultry nutrition in Africa. Two thousand questionnaires were administered to randomly selected respondents in all the ten regions of Ghana. With regards to social factors, entomophagy was found to be influenced by age, gender, education and occupation. Entomophagy is practiced across all age groups and gender in Ghana. Proportionally, 90, 78 and 74% of the aged (60+), middle aged (31-50) and the youth (18-30), respectively, were observed to consume various insect species. Ecologically, entomophagy was more pronounced in rural than urban areas. Over 87% of respondents who consume edible insects acquire them through harvesting/trapping. Four insect species were identified as feed for animals. The majority (81.6%) of the respondents consume insects as a source of protein, 9.6% for cultural reasons, 5.6% for medicinal values and 3.0 and 0.2%, respectively, for recreational and religious reasons. Gender has the least influence on entomophagy. Considering the economic, ecological and nutritional importance of edible insects in traditional Ghanaian foods, attention should be given to sustainable environmental harvesting practices.

Advent of technology has caused growing interest in using computers to convert conventional paper and pencil-based testing (Henceforth PPT) into Computer-based testing (Henceforth CBT) in the field of education during last decades. This constant promulgation of computers to reshape the conventional tests into computerized format permeated the language assessment field in recent years. But, enjoying advantages of computers in language assessment raise the concerns of the effects that computerized mode of testing may have on CBT performance. Thus, this study investigated the score comparability of Vocabulary in Use test taken by 30 Iranian undergraduate students studying at a state university located in Chabahar region of Iran (CMU) to see whether scores from two administrations of testing mode were different. Therefore, two similar tests were administered to the male and female participants on two testing mode occasions with four weeks interval. Employing One-Way ANOVA statistical test to compare the mean scores and Pearson Correlation test to find the relationship between mode preference and performance revealed that two sets of scores were not different and gender difference was not also considered a variable that might affect performance on CBT. Based on the results, computerized version of the test can be considered a favorable alternative for the state undergraduate students in Iran.

Background: The awareness of people’s health knowledge and behavior on COVID-19 has helped guide education and health promotion policies, and examination of people’s opinions on governance measures against this disease will guide policymakers in making more decisions and responsiveness. Objectives: This study aimed to investigate people’s knowledge and behaviors toward COVID-19 and their views on adopted public policies against this disease in Maragheh, a city in the Northwest of Iran. Methods: This study was a cross-sectional, analytical study that was done in urban areas of Maragheh from 13 November to 20 December 2020. The sample size was estimated at 672 participants, and the sampling method was stratified random. The data collection instrument was a researcher-made questionnaire that consisted of four sections: demographic information, health behaviors, respondent’s knowledge of COVID-19, and their viewpoints on adopted public policies against this disease and was shared online. The one-way ANOVA, Pearson correlation, and multiple regression were used to analyze data with SPSS version 23. Results: The mean scores of people’s knowledge (6.42 ± 1.2) out of 9 and health behaviors (34.8 ± 3.9) of 36 were moderate. The majority of respondents had high levels of knowledge and also behavior about keeping the physical distance (98.5%) and proper handwashing (97.9%). Knowledge (β = 0.23) and male (β = -0.27) were the predictors of health behaviors (p < 0.001, F = 12.47). The investigation of myths on COVID-19 indicated that 17% and 41.1% of the respondents believed that alcohol consumption and using garlic and herbal drinks are effective in the prevention and 57.7% of them believed that holding the breath for 10 seconds is a sign of being healthy. People’s views on the COVID-19 control policies were assessed to be at the medium level (48.2 ± 7.5) of 65. The most effective policies against COVID-19 from the people’s opinions consisted of lockdown policies (96.4%), schools’ closure (95.9%), and constraints on intercity trips (91.3%). Conclusions: It seems necessary to strengthen measures on health knowledge promotion and implementation of health education interventions on protective behaviors of COVID-19 in such a way that right beliefs are replaced with wrong ones. Based on positive public opinions on Lockdown interventions, re-applying these policies is recommended to get the cities out of the high-risk situation.

Objective: Marital satisfaction is considered as satisfaction with a marital relationship on which the presence of a child has different effects. Concerns about a childfree life and its effect on marital satisfaction in infertile couples are very critical. Therefore, this study was intended to characterize and compare concerns about a childfree lifestyle and the need for parenthood and their relationship with marital satisfaction in infertile couples. Method: A total of 200 men and 200 women who referred to fertility centers in Tehran participated in this cross-sectional study. Convenience sampling method was used for sampling. Demographic survey, ENRICH Marital Satisfaction Scale, and Fertility Problem Inventory were used for data collection. The resulting data were analyzed using descriptive and analytical statistical tests (Pearson Correlation Coefficient and Stepwise Regression). Results: The mean scores for concern about a childfree lifestyle and the need for parenthood in women were significantly higher than in men. The variables rejection of a childfree lifestyle and the need for parenthood were respectively predictors of marital satisfaction in women and men. Conclusion: Since marital satisfaction in infertile couples is affected by their feelings about having a child and becoming a parent, it is therefore suggested that appropriate counseling be provided in supportive healthcare programs for infertile couples to promote their marital satisfaction.
