Successful Manager

The purpose of this research is to determine whether there are differences between managers’ perceptions about the characteristics of a successful manager. It is based on Schein’s studies of gender role stereotypes and the characteristics required to be considered a successful manager. The hypotheses, one for men and one for women, are that managers will perceive that successful ones have attitudes, characteristics and temperaments that are more commonly attributed to men in general than to women in general. The slightly modified Schein Descriptive Index questionnaire to a sample of 268 managers working in Lima. Interclass correlation coefficients (r’) were calculated from two random group analysis of variance of the 92 descriptive items. In conclusion, it is found that while the hypothesis in confirmed in male managers, the same is not true in female managers, who perceive thar both men and women have characteristics of successful managers. Another finding is that age and years of experience moderate the perceptions of women, while the level of education moderates those of men.

We studied the influence of levels of income and education on QuickDASH scores. The scores were collected in a random sample of 1376 residents of Norway. The level of income was divided into four bands and level of education into five bands. The mean QuickDASH score for both men and women fell with every increase in education and income level. For women the mean score was 30 for those with the shortest education and 9 for those with the longest ( p < 0.001). The corresponding figures for men were 19 and 7 ( p < 0.01). The women with the lowest level of income had a mean score of 23, compared with 8 for women with the highest income level ( p < 0.001). For men the corresponding mean scores were 20 and 5 ( p < 0.001). Analysis of variance showed that age alone accounted for 16% of the variability of the scores among women and 7% among men. When levels of education and income were added to the analysis, these three factors accounted for 21% of the variability among women and 13% among men. We conclude that socioeconomic factors significantly influence QuickDASH scores. Level of evidence: 3

Balance Error

Context:The Balance Error Scoring System (BESS) is the current standard for assessing postural stability in concussed athletes on the sideline. However, research has questioned the objectivity and validity of the BESS, suggesting that while certain subcategories of the BESS have sufficient reliability to be used in evaluation of postural stability, the total score is not reliable, demonstrating limited interrater and intrarater reliability. Recently, a computerized BESS test was developed to automate scoring.Objective:To compare computerderived BESS scores with those taken from 3 trained human scorers.Design:Interrater reliability study.Setting:Athletic training room.Patients:NCAA Division I student athletes (53 male, 58 female; 19 ± 2 y, 168 ± 41 cm, 69 ± 4 kg).Interventions:Subjects were asked to perform the BESS while standing on the Tekscan (Boston, MA) MobileMat® BESS. The MobileMat BESS software displayed an error score at the end of each trial. Simultaneously, errors were recorded by 3 separate examiners. Errors were counted using the standard BESS scoring criteria.Main Outcome Measures:The number of BESS errors was computed for the 6 stances from the software and each of the 3 human scorers. Interclass correlation coefficients (ICCs) were used to compare errors for each stance scored by the MobileMat BESS software with each of 3 raters individually. The ICC values were converted to Fisher Z scores, averaged, and converted back into ICC values.Results:The double-leg, single-leg, and tandem-firm stances resulted in good agreement with human scorers (ICC = .999, .731, and .648). All foam stances resulted in fair agreement.Conclusions:Our results suggest that the MobileMat BESS is suitable for identifying BESS errors involving each of the 6 stances of the BESS protocol. Because the MobileMat BESS scores consistently and reliably, this system can be used with confidence by clinicians as an effective alternative to scoring the BESS.

This study examined the coefficients of restitution (e) of selected balls used in team sports for the visually impaired: beep baseball and goal ball. Specifically, a basketball was compared to two men's standard goal balls, and a softball was compared to three different types of beep baseballs. The e for all balls was calculated by dropping each ball five times from heights of 6 ft (1.83 m) and 19.25 ft (5.88 m). A Sony reel-to-reel videotape recorder was used to record rebound heights on a background scale for each ball dropped. Reliability tests of the procedures yielded correlation coefficients (r) of 0.996 and 0.998 for the 6 ft (1.83 m) and 19.25 ft (5.88 m) drops, respectively. Two two-factor analysis of variance (ANOVA) tests yielded significant differences across ball type and height of drop for the basketball and goal balls and for the softball and beep baseballs, respectively (p < 0.001). The es for the more recently developed beep baseballs are close to that of the standard softball, indicating a possible danger to visually impaired participants in beep baseball.

This study investigated customers' preferences of payment systems and the influence of demography on the attitude of customers towards e-payment services. Survey responses were received from 558 bank customers. The t-test and the analysis of variance were employed to examine the differences in perception of security, ICT literacy, customer satisfaction, and the use of e-payment services based on customers' age, gender, and the level of education. The findings revealed no significant differences between the male and female customers in the use of e-payment services. However, the male customers had higher ICT skills, yet perceived e-payment services less secured. Moreover, there were no significant differences in satisfaction and e-payment use, though, customers with higher level of education felt less secured using the services. Also, whereas the older customers were more satisfied with e-payment services, the younger customers had more ICT skills and use the services much more. These findings are necessary for formulating strategies for marketing e-payment services.

Analogue Scales

The aim of this study was to evaluate the psychometric properties of patient-reported visual analogue scale (VAS) ratings. All of the participants (100 Polish-speaking adults) completed a Tinnitus Functional Index (TFI) once and a 4-component VAS twice over a period of 3 days. Spearman’s correlation coefficients between the VAS score and global TFI ranged from ρ = 0.52 for VAS-coping (VAS-C) to ρ = 0.81 for VAS-annoyance (VAS-A). Using the Bland-Altman method, the agreement ranged from 93% for VAS-A to 96% for VAS-distress (VAS-D). Interclass correlation coefficients ranged from 0.67 for VAS-C to 0.90 for VAS-A. The VAS cutoff points representing significant tinnitus severity ranged from 45 points for VAS-C to 66 points for VAS-D. VAS scales are a valid and reliable brief screening tool for obtaining quick information about tinnitus.

ABSTRACT Introduction In endodontic treatment for permanent teeth, it is important to estimate the working length precisely. Currently, various methods are used in clinical practice for working length estimation. The objective of this study is to compare the accuracy of root canal length in permanent teeth determined by electronic apex locators, conventional and digital radiography. Materials and methods A total of 50 single rooted permanent teeth with mature apices were extracted for periodontal reasons and obtained from different sources without caries were studied. The radiographic measurements were done using paralleling technique. Electronic measurements were done next using third generation, DentAport ZX. Actual canal length of each tooth was measured using direct observation of the apical exit of the file. Measurements obtained from radiographic and electronic methods were compared to the actual tooth length. Interclass correlation coefficients and failure rate for each method and their combinations were calculated using STATA 12.0 software. Results The measurements obtained through all the three techniques showed high interclass correlation coefficients and excellent level of agreement. The failure rate of measurements obtained through conventional radiography, digital radiography and electronic apex locators was 38, 30 and 22% respectively. Combination of conventional radiography with electronic apex locator showed an accuracy of 90%, while combination of digital radiographs and electronic apex locators given an accuracy of 96%. Conclusion A combination of digital radiographic and apex locator methods for determining the root canal length in permanent teeth can be considered safe, reliable and precise.

Purpose: To investigate the repeatability of a combined Dual-Scheimpflug placido disc corneal topographer (Zeimer Galilei G4) with respect to keratometric indices used to monitor progression of keratoconus (KCN). Methods: Patients with KCN were prospectively enrolled. For each eye lacking history of corneal surgery, 5 measurements were taken in succession. Eyes in which 3 or more measurements could be obtained (defined by the device's 4 image quality metrics) were included in the analysis. The repeatability limits (RL) and interclass correlation coefficients (ICC) were calculated for various parameters. Results: 32 eyes from 25 patients met all image quality metrics, and 54 eyes from 38 patients met at least 3/4 criteria (all except the placido image quality metric). RLs for key parameters when 4/4 or 3/4 image quality metrics were met included: 0.37 and 0.77 diopters (D) for steep simulated keratometry, 0.79 and 1.65 D for maximum keratometry, 13.80 and 13.88 degrees for astigmatism axis, 0.64 and 0.56 um for vertical coma magnitude, and 3.76 and 3.84 um for thinnest pachymetry, respectively. The ICCs for all parameters were excellent [above 0.87 except for spherical aberration (0.77)]. Conclusions: The dual-Scheimpflug placido disc corneal topographer is highly repeatable in quantifying parameters used in monitoring KCN. Excellent placido images are difficult to capture in eyes with KCN, but when available, increase the reliability of the measurements. The RLs may be especially helpful in detecting progression in mild KCN when interventions such as corneal cross-linking or intrastromal corneal ring segments are most beneficial.

Gender differences which generats gender role do not need to be refused as long as they do not cause undesirable impacts. However, the problem is that gender role creates unequality structures in particular aspects such as can be found in Marital Laws. Some sections of Marital laws are considered gender bias for women. For instance, section 31  verse 3 and section 4 are categorized as irrelevant sections to build gender as well as human rights equality which been recommended by CEDAW convention (Convention on the Elimination of Discrimination Againts Women) and Act no 7/1984. Therefore, these efforts should be taken to establish the Act or the regulation based on gender perspective to achieve equality and justice for both sexes (men and women) in all aspects particularly in a family relationship.

The objective of the investigation is to establish the effect of the protection measures established by the government to reduce the contagion by Covid -19 in the district of Barranca during the second wave of infections. Data were collected on compliance with protection measures such as distancing, use of masks, visors and disinfection with alcohol in public places such as streets, markets, banks and parks. For this, data collection instruments based on visual inspection were used to verify the appropriate use of protection measures, as well as a survey regarding the use of alcohol as a disinfectant; and the data obtained was processed through basic statistics and correlation with the data reported by the Ministry of Health of positive infections by Covid-19. It was determined that there is a growth relationship between compliance with protection measures and the number of positive infections, with correlation coefficients for distance of 0.7458, use of 0.6710 masks, 0.8784 visors and use of alcohol as a disinfectant of 0.7310. Regarding the analysis of variance, it is obtained that the use of visors influences the number of positive infections, which is why it is concluded that maintaining distance, in addition to the use of masks and disinfectant alcohol are effective measures to control the number of infections per coronavirus.
