The paper includes an assessment of damageability of varieties and forms of apple by green apple aphids in the Republic of Tatarstan. An insignificant variability of damageability of leaves and annual shoots of green aphids was established by year in one half of the studied apple varieties and the average variability - in the second half of the varieties. An insignificant positive correlation is established between the degree of damage to the leaves and shoots of green apple aphids and damage to the leaves by the scab (r = 0.85), the hydrothermal coefficient of the vegetation (r = 0.78) and summer periods (r = 0.68), the amount of precipitation the summer period (r = 0.70), the average temperature in the summer period (r = 0.57) and the average temperature in April (r = 0.64). An insignificant negative correlation was found between the degree of damage to varieties and forms of apple trees by aphids and the amount of precipitation in April (r = –0.14). The manifestation of the sign “damaging the leaves and shoots of green apple aphids” is more influenced by the conditions of the year than the genotype of varieties, forms and the interaction of the genotype with the conditions of the year. The varieties Renet Povolzhya, Kamskaya and Komsin are distinguished according resistance to green apple aphid.

AbstractThe planning-performance literature suggests that there is a weak positive correlation between strategic planning and financial performance. This study has been undertaken to determine whether this weak positive correlation is true for Australian firms.Strategic planning for the purposes of this study is arranged in three levels of planning complexity. A sample of 77 listed firms was surveyed to determine their level of planning complexity, and this was correlated with the firm's financial performance over a three year period.A range of statistical tests did not reveal any significant correlation between strategic planning at any of the three levels and the financial performance of the firm. This negative finding is generally in line with other recent studies conducted in Australia, the United States and the United Kingdom.However, positive correlations were found with several subjective performance measures, suggesting that respondents generally believe that strategic planning is helping their company.

In 1953, 1954, and 1955 a species of leaf miner heavily infested leaves of apple trees in an orchard at Farnham, Que., causing severe damage to the crop. The pest was present on all apple varieties but was particularly abundant on Cortland. This infestation is apparently the first known to cause serious injury in Quebec.Specimens were determined by Dr. T. N. Freeman, Entomology Division, Ottawa, as of Lithocolletis malimalifoliella Braun. This pest has not been previously reported from the Province of Quebec. It has been reported as a persistent and sometimes serious pest of apple in the Annapolis Valley, N.S. (Cameron and Patterson, 1941; Patterson and Neary, 1943), but does not appear to have been reported elsewhere in Canada. Under Quebec conditions L. malimalifoliella has two complete generations and a partial third per year and overwinters in the pupal stage. A survey revealed the pest to be present in all major apple-growing areas of the province.

Context Throwing a baseball is a dynamic and violent act that places large magnitudes of stress on the shoulder and elbow. Specific injuries at the elbow and glenohumeral joints have been linked to several kinetic variables throughout the throwing motion. However, very little research has directly examined the relationship between these kinetic variables and ball velocity. Objective To examine the correlation of peak ball velocity with elbow-valgus torque, shoulder external-rotation torque, and shoulder-distraction force in a group of collegiate baseball pitchers. Design Cross-sectional study. Setting Motion-analysis laboratory. Patients or Other Participants Sixty-seven asymptomatic National Collegiate Athletic Association Division I baseball pitchers (age = 19.5 ± 1.2 years, height = 186.2 ± 5.7 cm, mass = 86.7 ± 7.0 kg; 48 right handed, 19 left handed). Main Outcome Measure(s) We measured peak ball velocity using a radar gun and shoulder and elbow kinetics of the throwing arm using 8 electronically synchronized, high-speed digital cameras. We placed 26 reflective markers on anatomical landmarks of each participant to track 3-dimensional coordinate data. The average data from the 3 highest-velocity fastballs thrown for strikes were used for data analysis. We calculated a Pearson correlation coefficient to determine the associations between ball velocity and peak elbow-valgus torque, shoulder-distraction force, and shoulder external-rotation torque (P < .05). Results A weak positive correlation was found between ball velocity and shoulder-distraction force (r = 0.257; 95% confidence interval [CI] = 0.02, 0.47; r2 = 0.066; P = .018). However, no significant correlations were noted between ball velocity and elbow-valgus torque (r = 0.199; 95% CI = −0.043, 0.419; r2 = 0.040; P = .053) or shoulder external-rotation torque (r = 0.097; 95% CI = −0.147, 0.329; r2 = 0.009; P = .217). Conclusions Although a weak positive correlation was present between ball velocity and shoulder-distraction force, no significant association was seen between ball velocity and elbow-valgus torque or shoulder external-rotation torque. Therefore, other factors, such as improper pitching mechanics, may contribute more to increases in joint kinetics than peak ball velocity.

Introduction. The number of people who are considered to be either overweight or obese continues to increase, worldwide. The aim of the paper was to determine the influence of overweight on the quality of life of health workers. Material and methods. The study of prevalence was used. We observed 108 health workers both men and women from the Institute for Public Health in the City of Nis. The questionnaire Obesity Related Well-Being 97 (ORWELL97) was applied in all health workers. Results. A hundred and five health workers filled in the ORWELL97 questionnaire. There were 40% of men and 60% of women; 72% of them were married and 28% of them were single; 68% were from the urban area and 32% were from the rural area. The average age was 29.5 (SD=3.2) and the average value of BMI was 25.4 (SD=4,0). There were 54 (48.6%) health workers having normal weight and there were 51(5.4%) who were considered overweight. No one was obese among them. The difference between the average sum of scores in the group of health workers who had normal weight and the group of health workers who were overweight was not statistically significant (t=1.1 i p<0.05). Nor was the difference statistically significant for the average sum of scores of subquestion O (t=3.6 and p<0.05), and subquestion R (t=2.9 and p<0.05). BMI showed a weak positive correlation with both occurrence and relevance of symptoms. A weak positive correlation of BMI was found with average sum of scores in the first, second and third groups of questions in ORWELL 97 questionnaire. Conclusion. According to the presented results, health workers who were overweight did not have lower quality of life than health workers who had normal weight.

BACKGROUND: Flexibility is important for general health and fitness, athletic performance, injury prevention and rehabilitation. Sedentary behavior of students leads to decreased physical fitness levels which affects flexibility. There is little evidence regarding relationship between BMI and flexibility. Aim: To study the relationship between BMI and flexibility and BMI and physical activity in young adults. Study Design: Observational study Place and Duration Of Study: The study was carried out at College of Physiotherapy, Sumandeep Vidyapeeth, Vadodara from September 2019 to March 2020. Methods: Males and females between 18 to 30 years were included in the study. BMI, Sit and Reach Test for low back and hamstring flexibility, Active Knee Extension Test (AKET) for hamstrings and Global Physical Activity Questionnaire (GPAQ) for physical activity levels were assessed. Results: 570 participants with mean age of 20.23±2.07 years were included. Mean BMI was 21.83±4.81 kg/m2. Number of females were 462 and males were 108. There was no significant correlation between BMI and flexibility of low back (P=.247) and hamstring (Rt) (P=.668) (Lt) (P=.354). BMI and GPAQ showed a statistically significant association (P=0.02). There was a weak positive correlation which was statistically significant between GPAQ and SART (P =0.000) and a weak negative correlation which was statistically significant between GPAQ and Rt AKET (P=0.004). Conclusion:  There was no significant correlation found between BMI and flexibility. There was a statistically significant association between BMI and physical activity, a weak negative correlation between GPAQ and hamstring flexibility and weak positive correlation between GPAQ and SART.

BACKGROUND The development of an author-level complementary metric could play a role in the process of academic promotion through objective evaluation of scholars’ influence and impact. OBJECTIVE The objective of this study was to evaluate the correlation between the Healthcare Social Graph (HSG) score, a novel social media influence and impact metric, and the h-index, a traditional author-level metric. METHODS This was a cross-sectional study of health care stakeholders with a social media presence randomly sampled from the Symplur database in May 2020. We performed stratified random sampling to obtain a representative sample with all strata of HSG scores. We manually queried the h-index in two reference-based databases (Scopus and Google Scholar). Continuous features (HSG score and h-index) from the included profiles were summarized as the median and IQR. We calculated the Spearman correlation coefficients (ρ) to evaluate the correlation between the HSG scores and h-indexes obtained from Google Scholar and Scopus. RESULTS A total of 286 (31.2%) of the 917 stakeholders had a Google Scholar h-index available. The median HSG score for these profiles was 61.1 (IQR 48.2), and the median h-index was 14.5 (IQR 26.0). For the 286 subjects with the HSG score and Google Scholar h-index available, the Spearman correlation coefficient ρ was 0.1979 (<i>P</i>&lt;.001), indicating a weak positive correlation between these two metrics. A total of 715 (78%) of 917 stakeholders had a Scopus h-index available. The median HSG score for these profiles was 57.6 (IQR 46.4), and the median h-index was 7 (IQR 16). For the 715 subjects with the HSG score and Scopus h-index available, ρ was 0.2173 (<i>P</i>&lt;.001), also indicating a weak positive correlation. CONCLUSIONS We found a weak positive correlation between a novel author-level complementary metric and the h-index. More than a chiasm between traditional citation metrics and novel social media–based metrics, our findings point toward a bridge between the two domains.
