The study objective is to investigate the relationship between behavioral finance and the decision to invest in green bonds for the sustainability of environmental assets in Peru. A survey with behavioral questions was applied to a sample of 54 respondents between July and October 2019. Spearman's rank correlation, independence tests, and logistic regression were used. Significant negative correlations were found between the level of education and risk aversion, and between age and risk aversion. A negative relationship was found between risk aversion and the feeling of comfort when investing in stock market instruments such as green bonds. Aversion to a loss in investment decisions was validated; most people choose low-risk fixed income instruments despite feeling safe investing in stocks. According to the logistic regression, the decision to invest in green bonds to improve environmental quality is explained by the variables “green bond rating” and “feeling of comfort (satisfaction) investing in green bonds.”

Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

Chest X Ray

Recent literature has reported that radiological features of coronavirus disease (COVID-19) patients are influenced by computed tomography. This study aimed to assess the characteristic chest X-ray features of COVID-19 and correlate them with clinical outcomes of patients. This retrospective study included 120 COVID-19 patients. Baseline chest X-rays and serial chest X-rays were reviewed. A severity index in the form of maximum radiological assessment of lung edema (RALE) score was calculated for each lung, and scores of both the lungs were summed to obtain a final score. The mean ± standard deviation (SD) and frequency (%) were determined, and an unpaired t test, Spearman’s rank correlation coefficient, and logistic regression analyses were performed for statistical analyses. Among 120 COVID-19 patients, 74 (61.67%) and 46 (38.33%) were males and females, respectively; 64 patients (53.33%) had ground-glass opacities (GGO), 55 (45.83%) had consolidation, and 38 (31.67%) had reticular-nodular opacities, with lower zone distribution (50%) and peripheral distribution (41.67%). Baseline chest X-ray showed a sensitivity of 63.3% in diagnosing typical findings of SARS-CoV-2 pneumonia. The maximum RALE score was 2.13 ± 1.9 in hospitalized patients and 0.57 ± 0.77 in discharged patients ( p value <0.0001). Spearman’s rank correlation coefficient between maximum RALE score and clinical outcome parameters was as follows: age, 0.721 ( p value <0.00001); >10 days of hospital stay, 0.5478 ( p value <0.05); ≤10 days of hospital stay, 0.5384 ( p value <0.0001); discharged patients, 0.5433 ( p value <0.0001); and death, 0.6182 ( p value = 0.0568). The logistic regression analysis revealed that maximum RALE scores (0.0932 [0.024–0.367]), (10.730 [2.727–42.206]), (1.258 [0.990–1.598]), and (0.794 [0.625–1.009]) predicted discharge, death, >10 days of hospital stay, and ≤10 days of hospital stay, respectively. The study findings suggested that the RALE score can quantify the extent of COVID-19 and can predict the prognosis of patients.

Objective To compare dental arch dimensions of children in the primary dentition with repaired unilateral clefts of the lip and palate (UCLP) to a noncleft group of a similar age and determine how the dimensions of the cleft arches relate to an index of treatment outcome. Method Dental study casts of 44 5- to 6-year-olds with complete UCLP (22 boys and 22 girls) from a single center, whose primary surgery had been carried out by one surgeon, were matched for age, sex, and ethnicity with dental study casts from a longitudinal growth study. Analysis of variance was used to ascertain differences in arch dimensions between the two groups. The cleft group casts were then assessed with an established index of surgical outcome, the 5-year-old index. Spearman's rank correlation coefficient was used to see how the arch dimensions of the cleft group related to the categories of the index. Results and Conclusions Maxillary arch dimensions were significantly smaller in the cleft group than in the noncleft group, irrespective of sex (p < .05). In the mandibular arch, there was no difference between the cleft and noncleft groups (p > .05). Maxillary arch dimensions of the cleft group correlated significantly with the 5-year-old index for arch length and intercanine width (p < .05) but not intermolar width (p = .842). This would suggest that the 5-year-old index is a suitable tool for assessing the outcome of treatment in the primary dentition for anteroposterior and anterior transverse arch dimensions.

This study has two purposes. First, we aim to identify the demography factors, namely gender, marital status, educational level, age, monthly income, and cognitive factor, namely casino-related job and emotional intelligence are predictive of problem gambling. Second, we propose and test whether perceived control of time over work moderates the relationship between emotional intelligence and level of problem gambling. Data are randomly collected from 310 respondents in Macao. Results of logistic regression showed that respondents who are male, married, have a low educational level, low emotional intelligence, high monthly income, and have a casino-related job have a higher tendency of becoming problem gamblers. In addition, results of moderated regression indicated that the negative relationship between emotional intelligence and level of problem gambling is found more negative when the employees’ perceived control of time over work is low. The implications of the findings are discussed.

The Relationship

Dairy farming contributes about eight percent of National Gross Domestic Product with an annual milk production of 3.43 billion litres in Kenya. It supports the livelihood of approximately four million Kenyans through food provision, income generation and employment. However, milk production per individual animal in Kenya, averaging six to seven (6-7) litres/cow/day, is low compared to the world’s best at 10,133 litres/cow/year (28 litres/cow/day) mainly due to factors including poor feeding. This means that Kenya produces an average of 20 litres of milk less per cow per day compared to the world’s best. The objective of this study was to determine the effect of mineral mix and concentrate feeds on milk revenue of smallholder dairy farmers in Kapseret sub County. The study was conducted between the months of January-March, 2020. Primary data was collected using closed and open ended questionnaires. Spearman’s Rank correlation was used to show the strength of the relationship between the variables. Multiple regression model was employed to assess the effect of supplementation on milk revenue. Results were presented in tables, and descriptive statistics such as percentages and frequencies. The results indicated a positive and statistically significant relationship between the variables (concentrate feeds and mineral mix) and milk revenue at (r=0.41, p=0.001) and (r=0.30, p=0.001), respectively. The relationship between mineral mix and concentrate feeds was positive and statistically significant (r=0.92, p=0.001). Subsequent feeding of homemade or commercial concentrates and mineral mix to dairy animals influenced milk revenue. The study concluded that mineral mix and concentrate feeds increased milk revenue of smallholder dairy farmers in Kapseret sub County. The study recommended the use of mineral mix and commercial concentrates or quality homemade concentrates in order to increase milk produce which affects farmers’ milk revenue.

Abstract Background: This paper examines the relationship between selected motivation factors that affect the attitude to work among medical doctors at public hospitals and the organizational performance of hospitals .Methods: This study was based on World Health Organization questionnaires designed to estimate motivation factors according to Herzberg’s motivation theory and to measure the level of organizational performance of hospitals by using the McKinsey model . A survey was conducted among physicians (n=249) with either surgical (operative) or nonsurgical (conservative) specialty in 22 departments/units of general public hospitals in Warsaw, Poland. The relationship between the chosen job motivation factors and organizational effectiveness was determined using Spearman’s rank correlation. Furthermore, 95% confidence intervals were calculated. The independent samples t-test was used to confirm statistically significant differences between the independent groups. Normality of the data was tested by the Kolmogorov–Smirnov test.Results: The survey revealed that motivation factors related to “quality and style of supervision” have the highest effect on the organizational performance of hospitals (Spearman’s rank correlation coefficient = 0.490; p<0.001), whereas “performance feedback” has the lowest effect on organizational performance according to the surveyed healthcare professionals (54% of physicians). Conclusion: The principles of Individual Performance Review should be incorporated into strategies designed to improve the organizational performance of hospitals (with NHS serving as a potential role model) in order to establish specific rules on how to share performance feedback with individual physicians. The present study contributes to literature on human resource management in the healthcare sector and highlights the importance of nonfinancial aspects in improving the organizational performance of hospitals.

Moderate Stress

Background: Menopause is the cessation of the last menstruation that occurs in the climacteric period and the hormone estrogen is no longer formed. The older the age, the more diseases suffered at the age of menopause, such as hypertension. Hypertension is a condition when a person experiences an increase in blood pressure either slowly or suddenly. The factors that cause hypertension are mostly due to stress. This study aims to determine the relationship between stress levels with the incidence of hypertension in postmenopausal women. Methods: The design of this research is correlational analytic. The sample is 50 respondents with the Stratified Random Sampling technique. The instrument used is a questionnaire. The results of the study were analyzed using the Spearman rank statistical test. Result: The results showed that there were 24 people (48.0%) with moderate stress levels and 18 people (36.0%) experiencing Stage I Hypertension. The results of the Spearman's Rank correlation test showed that the value of value = 0.000 was smaller than the value of = 0.05 so that H0 is rejected and H1 is accepted, meaning that there is a relationship between stress levels and the incidence of hypertension in postmenopausal women. Conclusion: It is expected that respondents will increase their knowledge about how to deal with stress so that they do not experience stress at a severe level so that it does not have a bad impact on them.

Purpose The first purpose of the present study is to investigate the coverage of journal articles in Physics in various sources of altmetrics. Secondly, the study investigates the relationship between altmetrics and citations. Finally, the study also investigates whether the relationship between citations and altmetrics was stronger or weaker for those articles that had been mentioned at least once in the sources of altmetrics. Design/methodology/approach The journal articles in Physics having at least one author from an Indian Institution and published during 2014–2018 in sources of altmetrics have been investigated. Altmetric.com was used for collecting altmetrics data. Spearman’s rank correlation coefficient (ρ) has been used as the data found to be skewed. Findings The highest coverage was found on Twitter (22.68%), followed by Facebook (3.62%) and blogs (2.18%). The coverage in the rest of the sources was less than 1%. The average Twitter mentions for journal articles tweeted at least once was found to be 4 (3.99) and for Facebook mentions, it was found to be 1.48. Correlations between Twitter mentions–citations and Facebook mentions–citation were found to be statistically significant but low to weak positive. Research limitations/implications The study concludes that due to the low coverage of journal articles, altmetrics should be used cautiously for research evaluation keeping in mind the disciplinary differences. The study also suggests that altmetrics can function as complementary to citation-based metrics. Originality/value The study is one of the first large scale altmetrics studies dealing with research in Physics. Also, Indian research has not been attended to in the altmetrics literature and the present study shall fill that void.

The Relationship

AbstractThe relationship between puberty and the cessation of luteal activity after nutritional restriction was evaluated in 15 Angus × Hereford heifers. Heifers attained puberty at a body weight of 297 (s.e. 6) kg and a body condition score (BCS) of 5·5 (s.e. 0·1) on a scale of 1 (emaciated) to 9 (obese). After 154 (s.e. 16) days of nutritional restriction, heifers became anoestrus at a weight of 273 (s.e. 8) kg and a BCS of 3·0 (s.e. 0·2). The Spearman's rank correlation coefficient between date of-puberty and date of cessation of luteal activity was (r = –0·49; P < 0·06). This indicates that the heifers that attained puberty first were the last to cease luteal activity during nutritional restriction.
