The present study contributes to the knowledge of epibionts recorded on sea turtles that nested on a beach in the South Pacific of Mexico. A total of 125 Lepidochelys olivacea turtles nested on Llano Real beach, Guerrero, Mexico, were examined. We collected 450 conspicuous organisms from 8 species from 43 turtles. The corresponding data analysis was carried out to obtain the relative abundance, the relationship between turtle sizes and the presence of organisms, the similarity of species between the sampling months, and the interspecific relationships between the epibionts and the turtles observed. Chelonibia testudinaria was the most abundant species, while Remora remora was the least abundant species. The turtles were divided into six body sections, with the greatest abundance of these organisms located in the head–neck section of turtles, and there was a significant difference in the size of the turtles that presented epibionts and those that did not. C. testudinaria showed greater similarity between sampling months, and the interspecific relationships recorded were commensalism, parasitism, amensalism, and protocooperation. This research contributes the first record of epibionts in L. olivacea nesting in Guerrero, Mexico.

This study aims to investigate the relationship between amateur football players’ mental readiness and difficulty in dealing with the level of emotion regulation. The study group consisted of 219 volunteer male athletes who actively played amateur league football in Bingol, Turkey during the 2018-2019 season. Along with a consideration of various demographic variables, the “Mental Readiness Scale” and the “Difficulty in Emotion Regulation Scale” have been used in this study. SPSS packaged software has been utilized for data analysis purposes. Descriptive statistics, Pearson Correlation and the One-Way ANOVA test have been utilized in the data analysis. According to the findings, a negative relationship has been determined between mental readiness and difficulty in emotion regulation on the part of the amateur football players. Furthermore, a statistically significant difference has been found between the variable of the football playing year and the total degree of mental readiness, mental preparation, cool-headedness and goals sub-dimensions (p< .05). Moreover, another statistically significant difference has been determined between the variable working period with the current coach and the total degree of mental readiness, mental preparation and cool-headedness sub-dimensions. As a consequence, the results suggest that as the mental readiness levels of the amateur players taking part in the study increase, the difficulty they experience in emotion regulation decreases. Additionally, it has been found out that as the football playing year and working period with the current coach increases, the athletes’ mental readiness levels go up, and the level of difficulty with regard to emotion regulation decreases.

Research method can be categorized as descriptive, correlation research. The study population consisted of all office employees who worked in 2014-2015 in offices in Esfaraen County of which 248 employees were selected using stratified random sampling. Data was collected through administrating three questionnaires, Sherer self-efficacy, Meyer and Allen organizational commitment and Barry Field-Roth job satisfaction. The results of data analysis using Pearson's correlation and multivariate regression showed that there was a significant positive correlation between self-efficacy and organizational commitment with job satisfaction of employees, and they predict it positively. Among different types of organizational commitment, affective commitment, normative commitment and continuance commitment were of significant positive relationship with job satisfaction of employees; however, only affective commitment and continuous commitment predicted it positively. The results obtained from data analysis using independent two-sample t-test showed that there was no difference between male and female employees' job satisfaction. The results of one-way analysis of variance showed that there was a significant difference in different age groups, different years of services and different levels of education for job satisfaction of employees. The result suggested that employees who had higher organizational commitment and self-efficacy were of higher job satisfaction.

Abstract There is little scientific evidence regarding the cumulative effect of purposeful heading. The head-neck-torso alignment is considered to be of great importance when it comes to minimizing potential risks when heading. Therefore, this study determined the relationship between head-neck-torso alignment (cervical spine, head, thoracic spine) and the acceleration of the head, the relationship between head acceleration and maximum ball speed after head impact and differences between head accelerations throughout different heading approaches (standing, jumping, running). A total of 60 male soccer players (18.9 ± 4.0 years, 177.6 ± 14.9 cm, 73.1 ± 8.6 kg) participated in the study. Head accelerations were measured by a telemetric Noraxon DTS 3D Sensor, whereas angles for the head-neck-torso alignment and ball speed were analyzed with a Qualisys Track Manager program. No relationship at all was found for the standing, jumping and running approaches. Concerning the relationship between head acceleration and maximum ball speed after head impact only for the standing header a significant result was calculated (p = 0.024, R2 = .085). A significant difference in head acceleration (p < .001) was identified between standing, jumping and running headers. To sum up, the relationship between head acceleration and head-neck-torso alignment is more complex than initially assumed and could not be proven in this study. Furthermore first data were generated to check whether the acceleration of the head is a predictor for the resulting maximum ball speed after head impact, but further investigations have to follow. Lastly, we confirmed the results that the head acceleration differs with the approach.

The objective of this study is to identify the relationship between life satisfaction and narcissism levels of students of the Physical Education and Sports School of Mardin Artuklu University located in southeastern Turkey. In the study, Satisfaction with Life Scale and Narcissistic Personality Inventory were employed in order to collect data. Sample of the study is comprised of a total of 155 Physical Education and Sports School students who voluntarily agreed to participate in the study. 56 participants were female and 99 participants were male. In the data analysis of this research, SPSS 20.0 software was utilized. Independent Samples T-Test, One-way Analysis of Variance (ANOVA) and correlation analysis were used in data analysis. At the end of the statistical analysis, it was found that female students had quantitatively higher narcissistic personality and life satisfaction scores than male students. Thus, it was inferred that female students behaved more narcissistically and were more engaged with life. However, along with the comparison of students&rsquo; narcissism and life satisfaction scores particularly on the basis of departments of Physical Education and Sports School at which students were enrolled, it was ascertained that there was no statistically significant difference in either narcissism scores or life satisfaction scores.

The aim of this study is to investigate the role of plasma level parameters during nesting activity and provide data potentially useful to future studies on the dynamics of reproductive and stress hormones in the most endangered sea turtle species in the world. Plasma parameters in the sea turtles, olive ridley (Lipodochelys oliveacea) and hawksbill (Eretmochelys imbricata) from Masirah Island, Oman, were analyzed relative to nesting stress. To date, no study has been conducted on plasma parameter levels in sea turtles during nesting. Field observations were conducted under ideal temperature conditions. At the time of sampling, there was no significant difference for cloacal, sand, air or water temperature for the two species. Electrolytes (Cl¯, Ca++, K+, Na+ and Mg++), cholesterol, urea, uric acid and osmolarity were measured during nesting. Both species were observed to spend between 1.5 and 2.00 hours on the nesting grounds. Some had successful oviposition and completed all nesting phases, while others with incomplete nesting phases failed to oviposit their  eggs. Under both conditions, the turtles of both species had an exhaustive and stressful nesting exercise. Plasma parameter values, both intra-specifically and inter-specifically, were not significantly different for oviposited and non-oviposited turtles. This may indicate that both species have the same physiological adjustment relative to plasma parameters whether or not the turtles oviposited their eggs.

Abstract. Basri NIA, Zakaria N. 2021. Butterfly communities (Insecta: Lepidoptera) at two recreational areas in Sungai Petani, Kedah, Peninsular Malaysia. Biodiversitas 22: 5039-5047. The knowledge on the butterfly diversity, especially in various habitats in Kedah is still poor. A study was conducted to determine and compare the diversity of butterflies at two recreational areas in Sungai Petani, Kedah, namely Bukit H and Taman Jubli Perak. This study was carried out starting from January 2021 until March 2021 with a total of nine sampling occasions at each site. Visual Encounter Survey (VES) was chosen as a sampling method. The butterflies were captured using a sweep net from 9am to 11am and 12pm to 2pm for each sampling site. A total of 145 individuals from 13 species from four families of butterflies were recorded. The most abundant species were recorded from the family Nymphalidae. Chilades pandava was the most abundant species obtained from the two recreational areas. From the t-test analysis, there was no significant difference between the diversity of Bukit H and Taman Jubli Perak. Shannon and Simpson's diversity indices showed both sites were interpreted as moderately low in diversity. This may be due to the different types of vegetation that exist at both sampling sites. This study will contribute to the first record of butterflies in Sungai Petani, Kedah, Peninsular Malaysia.

Summary Aim: Tumor scintigraphy with 201-TICI is an established diagnostic method in the follow-up of differentiated thyroid cancer. We investigated the relationship between thyroglobulin (Tg) level and tumor detectability. Subject and methods: We analyzed the scans of 122 patients (66 patients with proven tumor). The patient population was divided into groups with Tg above (N = 33) and below (N = 33) 5 ng/ml under TSH suppression or above (N = 33) and below (N = 33) 50 ng/ml under TSH stimulation. Tumor detectability was compared by ROC-analysis (True-Positive-Fraction test, specificity 90%). Results: There was no significant difference (sensitivity 75% versus 64%; p = 0.55) for patients above and below 5 ng/ml under TSH suppression and a just significant difference (sensitivity 80% versus 58%; p = 0.04) for patients above and below 50 ng/ml under TSH stimulation. In 18 patients from our sample with tumor, Tg under TSH suppression was negative, but 201-TICI-scan was able to detect tumor in 12 patients. Conclusion: Our results demonstrate only a moderate dependence of tumor detectability on Tg level, probably without significant clinical relevance. Even in patients with slight Tg elevation 201-TICI scintigraphy is justified.
