Previous investigators had found that self-pacing enhances performance of perceptual-motor tasks. To determine whether self-pacing would increase the observed relationship of information-processing rate with measures of intelligence 31 matched pairs of students, matched for Otis IQ, were randomly assigned to a Work-paced or Self-paced simple arithmetic task. The relationship of the mean response latency to Otis IQ was moderate in each group. However, there was no significant difference between groups in the magnitude of relationship. Self-pacing did not enhance the relationship. The magnitude of the relationship with Otis IQ was relatively high considering the complexity and duration of the arithmetic test.

Self Administered Questionnaire

This study focused on the reliability and validity of the stress questionnaire and the relationship of responses to types of work. This self-administered questionnaire was distributed to all 799 employees of a company. 792 responded. There are 21 items with yes-no responses for which the score was the sum of assigned weights. Types of work represented manager, technical manufacturer, clerk, manufacturer, and sales. From a principal axis factor analysis three factors were extracted for men and for women, respectively. There was a significant difference in mean score among five groups of workplace positions by Kruskal-Wallis one-way analysis of covariance ( p = .04). The mean value for manager was not significant but was relatively lower than those of the other positions, suggesting that being a manager was less stressful. Confirmation with the testing of an independent sample is also needed to validate the consistency of the association.

Background and Aim: Spiritual attitude is one of the factors affecting mental health of students. The purpose of this study was to determine the relationship of religious attitudes with self-control and self-discrepancy (S-D) in students of Shahrekord University of Medical Sciences (SKUMS) in 2017. Methods: In this cross-sectional study, 328 students of the SKUMS were studied. The participants completed Tangney Self-control Survey, Higgins Self-discrepancy Questionnaire, a religious attitude questionnaire, and a checklist of demographic information. For data analysis, in addition to descriptive statistics, independent t-test, Pearson correlation coefficient, and one-way ANOVA were used. Stata software was used to analyze the data. Results: The mean values of religious attitude, self-control, and self-discrepancy were higher in women in comparison with men (P< 0.05). There was a significant difference between self-control religious beliefs, actual-self minus actual-self (S-D2), and self-discrepancy in terms of total monthly income of all family members (P< 0.05). Academic discipline was significantly associated with religious attitude, ideal-self minus actual-self (S-D1), S-D2, and S-D (P< 0.05), but self-control difference was not significant (P= 0.84). There was a linear relationship, significant correlation of religious attitude with the mean values of self-control, required self, actual-self, idea-self, self-discrepancy, and S-D1 and S-D2 (P< 0.05). Conclusion: According to the results of this study, religious attitude was associated with self-control, self-discrepancy, and their dimensions.

The Relationship

The relationship of body weight to wool production was examined in a flock of Merino sheep of South Australian strain over a period of 7 years. In only one out of 10 groups examined was there a significant correlation between body weight and the amount of clean wool produced per unit area of midside skin. It is concluded that body weight and wool production per unit area of body surface are independent. In all groups there was a highly significant correlation between clean fleece weight and clean wool per unit area of body surface in the midside region. The regression of log fleece weight on log body weight was determined in 15 groups. In no case was the regression coefficient significantly different from 0.60. As the regression of log surface area on log body weight in sheep is of the order of 0.60, it is concluded that wool production is proportional to fleece-bearing surface. The mean regression coefficients of log fleece weight on log body weight, calculated within sire and year groups, were: rams, 0.52 ± 0.056; ewes, 0.61 ± 0.038; wethers, 0.30 ± 0.068. There were no significant differences between sires in the regression of log fleece weight on log body weight. There were, however, highly significant differences between sire groups in mean log fleece weight, after adjustment for differences in log body weight. Skin areas 3 by 3 cm were tattooed on the left midside of 24 lambs at 1 month of age. The wool produced on these areas, and the areas of the tattoos, were measured at 4-monthly intervals from 4 months of age until 28 months. The amount of wool produced m7as proportional to the area in each of the six periods. There was also a highly significant difference between periods and between sheep in the amount of wool produced after adjustment for differences in tattoo area.

This study examines the relationship of the degree of glomerular hypertrophy in nephronopenia to the development of focal segmental glomerulosclerosis (FGS) in humans. To this end, group mean glomerular diameters in a variety of acquired and congenital nephronopenic states in native kidneys and long-surviving renal allografts with and without FGS were analyzed and compared. The results indicate that all groups of native nephronopenic kidneys without FGS develop significant and equivalent glomerular hypertrophy. By contrast, long-surviving renal allografts without FGS do not undergo glomerular hypertrophy. For groups with FGS, long-surviving renal homografts had a significantly smaller mean glomerular diameter when compared with any other group of native nephronopenic kidneys. There was no significant difference among group mean glomerular diameters of native nephronopenic kidneys with FGS. Pairwise comparisons in each category of nephronopenia indicated that, except in the groups with uninephrectomy, the mean glomerular diameters were significantly larger in those with FGS than without. These observations are interpreted to indicate that nephronopenic individuals with native kidneys, by undergoing glomerular hypertrophy, consume much or all their capacity for glomerular enlargement. This brings them closer to their maximal diameters at which FGS develops. Finally, long-surviving renal allografts without nephronopenic FGS do not undergo glomerular hypertrophy. However, when FGS develops in long-surviving allografts, it does so at glomerular diameters significantly smaller than in native nephronopenic kidneys, reflecting their decreased capacity to undergo glomerular hypertrophy, acquiring maximal diameters at a smaller dimension than native nephronopenic kidneys.

BACKGROUND: Previous studies reported that familial factors such as birth order and mothers atopy might influence cord blood levels and development of allergies.AIM: The aim of the study was to evaluate the relationship of cord blood IgE and maternal IgE with birth order and mothers history of allergy in Albanian mother/neonate pairs.MATERIAL AND METHODS: Study population represented 291 mother-infant pairs. Mothers were interviewed with a questionnaire for personal history of allergy and pregnancy history whereas serum IgE levels were determined using sandwich IRMA assay.RESULTS: The mean level of cIgE in neonates with detectable levels was 1.59 (n = 78). No significant difference in means of cIgE was found between first born and later born neonates (p = 0.232) and between neonates of mothers with a negative and positive history of allergy (p = 0.125). Also, no significant difference was found between means of mIgE by birth order, whereas there was a significant difference of mIgE between mothers with and without a history of allergy (p = 0.01). In a group of neonates with detectable cIgE levels, maternal IgE levels were moderately correlated with cIgE levels.CONCLUSION: Cord blood IgE is not affected by birth order and mothers history of allergy, whereas mothers IgE are affected by the history of allergy but not by birth order.

The present report is based on reanalysis of data of Marisi (1969) in order to examine the relationship of consistency of motor response among the component responses of a single motor task. 120 high school Ss were tested on a special task, the rho. A single trial on this motor task can be logically separated into three component motor responses: reaction time, a short circular movement, and a short linear movement. The results indicated that consistency of motor response was moderately reliable within the response components but tended to be response-component specific. Further, both the reliability and specificity of motor-response consistency were independent of the size of the mean performance scores.

External ventricular drainage (EVD) is widely used in patients with a traumatic brain injury (TBI). However, the EVD weaning trial protocol varies and insufficient studies focus on the intracranial pressure (ICP) during the weaning trial. We aimed to establish the relationship between ICP during an EVD weaning trial and the outcomes of TBI. We enrolled 37 patients with a TBI with an EVD from July 2018 to September 2019. Among them, 26 were allocated to the favorable outcome group and 11 to the unfavorable outcome group (death, post-traumatic hydrocephalus, persistent vegetative state, and severe disability). Groups were well matched for sex, pupil reactivity, admission Glasgow Coma Scale score, Marshall computed tomography score, modified Fisher score, intraventricular hemorrhage, EVD days, cerebrospinal fluid output before the weaning trial, and the complications. Before and during the weaning trial, we recorded the ICP at 1-hour intervals to calculate the mean ICP, delta ICP, and ICP burden, which was defined as the area under the ICP curve. There were significant between-group differences in the age, surgery types, and intensive care unit days (p=0.045, p=0.028, and p=0.004, respectively). During the weaning trial, 28 (75.7%) patients had an increased ICP. Although there was no significant difference in the mean ICP before and during the weaning trial, the delta ICP was higher in the unfavorable outcome group (p=0.001). Moreover, patients who experienced death and hydrocephalus had a higher ICP burden, which was above 20 mmHg (p=0.016). Receiver operating characteristic analyses demonstrated the predictive ability of these variables (area under the curve AUC=0.818 [p=0.002] for delta ICP and AUC=0.758 [p=0.038] for ICP burden>20 mmHg). ICP elevation is common during EVD weaning trials in patients with TBI. ICP-related parameters, including delta ICP and ICP burden, are significant outcome predictors. There is a need for larger prospective studies to further explore the relationship between ICP during EVD weaning trials and TBI outcomes.

To investigate the relationship of MUC1, MUC5AC, and the syndrome of spleen and stomach, 109 subjects (34 peptic ulcer (PU), 62 chronic gastritis (CG), and 13 healthy volunteers (CON)) were included. All the subjects included were surveyed with questionnaire to classify them into damp-heat syndrome of spleen and stomach (DHSS), spleen-qi deficiency syndrome (SQD), and CON, examined by gastric endoscope, and biopsied. Rapid urease and methylene blue staining (MBS) were performed on every subject to diagnose for Helicobacter pylori (Hp) infection, and both were defined as Hp-positive. Hematoxylin and eosin (HE) staining was performed on every specimen to explore the histomorphology, inflammatory degree, and inflammatory activity of different groups; then Elivision™ plus kit was used to test the expression of MUC1 and MUC5AC. All the results of digital images were reviewed by two experts blindly. The inflammatory degree with Hp infection was higher than those uninfected or CON, but no significant difference was found between DHSS and SQD. And the expressions of MUC5AC with positive Hp was higher than those with negative Hp or CON regardless of the deficiency and solid syndrome of spleen-stomach but not for MUC1. We speculate that the deficiency and solid syndrome of spleen-stomach is a condition like Tai Ji symbol of dynamic equilibrium, showing the higher expression of MUC5AC but no change of MUC1 in the circumstance of Hp infection.

<p>This study investigated whether learning strategies had made any impact on learners’ achievement and explored whether learning motivation was correlated with learning strategies. The participants of this study were the students from the EFL (English as a Foreign Language) intermediate level course at a college in Taiwan. The students were given a pretest and a posttest. The mean scores of these tests were compared with a SILL survey (Strategies Inventory for Language Learning) at the end of the investigation. The participants’ course performance was compared with their use of learning strategies. The assumption of the relationship between learning strategies and motivation is that motivated learners have a greater desire to seek out solutions or support from others and employ more strategies to process the new information. The results of this investigation revealed that only the memory strategies had a significant difference in the posttest of Group A on the independent sample t-test analysis.</p>

Background Many studies have investigated the adherence to professional codes of ethics by nurses. However, no study has explicitly examined the relationship between workload and adherence to professional codes of ethics among Iranian nurses. Objective This study aimed to explore the relationships between workload and adherence to professional codes of ethics among a sample of Iranian nurses. Materials and Methods A cross-sectional descriptive study was conducted on 213 nurses who were randomly selected from the different wards of Shahid Beheshti Hospital of Kashan, Iran. Data collection instruments included a personal characteristics questionnaire, the Nursing Ethics Questionnaire, and the National Aeronautics and Space Administration Task Load Index. The Chi-square, the Spearman correlation coefficient, the Kruskal–Wallis, and Mann–Whitney U tests were used to analyze the data. Results A majority of nurses were females (77.5%), married (79.3%), and permanently employed (55.4%). The mean of the overall perceived workload and adherence to professional codes of ethics were 76.36 ± 13.64 and 13.98 ± 2.58, that were at high and moderated level, respectively. Spearman correlation test showed no significant correlation between perceived workload and adherence to professional codes of ethics ( r = 0.03, P = 0.6). A significant difference was found between the mean scores of adherence to professional codes of ethics in nurses working in different departments ( P < 0.001). Conclusion Participating nurses perceived high levels of workload but their mean adherence to professional codes of ethics was at a moderate level. The perceived workload was indirectly correlated with adherence to professional codes of ethics.
