Abstract. Syukur A, Zulkifli L, Idrus AA, Hidayati BN. 2021. Species diversity of seagrass-associated bivalves as an ecological parameter to support seagrass conservation along with the Coastal Waters of South Lombok, Indonesia. Biodiversitas 22: 5133-5144. Seagrass has a role in supporting the survival of marine life, such as bivalves. This study aimed to investigate the relationship between bivalve species diversity as a parameter for seagrass conservation. The research approach was through observation and data collection for seagrass and bivalves using quadrant and transect methods—Analysis of the data through descriptive statistical analysis, ANOVA, and Pearson correlation. The number of seagrass species in the six research sites was nine. Furthermore, the species composition of bivalves consisted of 11 families comprising 47 species. The ANOVA results showed a significant difference based on the F-count value, higher than the F-table value of the three ecological indices (H', E, and Ki). Two ecological indices, namely H' and Ki, have r values ??less than 0.5 for all environmental parameters (temperature, brightness, pH, salinity, DO, phosphate, and nitrate) and show no significant correlation. However, the E index value has an r value greater than 0.5 for nitrate, salinity DO, and phosphate. The highest significance value of the four environmental variables is for nitrate, with an r = 0.875. The conclusion is that the richness and abundance of seagrass-associated bivalves in the study area are predetermined by the characteristics of the seagrass environment, especially the substrate. Secondly, seagrasses could create a suitable substrate for bivalves to survive. Therefore, the indicator of the presence of associated Bivalvia species can be a parameter for local scale seagrass conservation at the study site.

Abstract Background Rotavirus is considered the main causal factor of severe gastroenteritis among infants and children globally. The association with severe rotavirus infection is mostly worse among the least developed countries, mainly due to inadequate access to medical care and poverty. This study was conducted to determine the seasonal effects in respect of diarrhea cases in children, the association between diarrhea cases and Rota2 vaccine in the Fanteakwa District of the Eastern Region of Ghana. Methods The study compares monthly diarrhea cases against children vaccinated with Rota2 extracted from DHIMS2 spanning May 2012 to December 2017 in Fanteakwa District. A univariate association between diarrhea cases and children vaccinated with Rota 2 was conducted using the R-software version 3.4.4 with the use of forecast, tseries and TSAPred. Pearson Correlation coefficient was also computed between monthly diarrhea cases and Rota 2 as well as lagged values of Rota 2 and Diarrhea cases. Results The study shows that February recorded the highest average number of diarrhea cases (172) over the period 2012 to 2017 with a standard deviation of 59. However, a one-way analysis of variance shows a significant difference amongst the monthly averages with an F-statistic of 0.042 and P-value of 0.064. It is observed that the correlations between each of the Rota2 doses and the lagged cases are positive, showing higher Rota2 doses a month ago ((Xt − 1),0.346 to0.735), two months ago ((Xt − 2),0.383 to 0.746), three months ago ((Xt − 3), 0.330 to 0.737) and four months ago ((Xt − 4), 0.236 to 0.723) are associated with lower diarrhea cases. The results also show that an increase in the previous two month’s Rota2 figures by 100 is associated with a significant decrease in the currently expected diarrhea cases by approximately 36. Conclusion Seasonal variations exist in the occurrence of diarrhea in children, with January recording the highest number of diarrhea cases (172). There is a relationship between episodes of diarrhea in children and Rota2 (p-value = 0.064); thus, the more children are vaccinated with Rota2, the less diarrhea cases are recorded. Diarrhea cases in Fanteakwa district are generally low, except 2013 and 2016 where the cases are higher than the rest of the other years.

Measuring the phytodiversity and determining environmental factors affecting the abundance and distribution of riparian plants of Zat sub-basin in Morocco were carried out in this study. A hypothesis was tested whether there is any statistically significant difference in environmental parameters and plants communities among the Zat River and its tributaries. For this purpose, water quality parameters such as temperature, pH, salinity, electrical conductivity, Dissolved Oxygen, nitrate and phosphorus concentration, and riparian plants diversity were estimated at 17 stations along the Zat River and its tributaries during the periods (2018 and 2019). The Canonical Correspondence Analysis (CCA) and Pearson correlation were preformed to assess the relationship between environmental parameters, and the distribution and abundance of riparian plants inventoried. The presence of 113 species was recorded, distributed between 43 families and 97 genera, 9 of which were floating-leaved, 24 submerged, and 80 emergent plants. The rare and threatened species inventoried were represented by 7 taxa, whereas 6 species are reported as endemic. Raunkiaer classification showed a dominance of therophytes (38.39%) over the other groups. According to CCA, the abiotic parameters (DO, elevation, salinity and nitrate concentration) were statistically significant parameters governing the distribution and abundance of the riparian plants inventoried. The results obtained reveal the state of the riparian vegetation in the Zat subBasin, therefore we can consider them as a reliable component for the assessment of the ecological status of the aquatic environment.

Aim: The aim of the study is to examine the relationship between leisure management and test anxiety levels of university students and their differentiation status in terms of some demographic variables. Methods: The relational survey model was used in the study, and there were 284 (147 male and 137 female) university students selected from the universe by convenient sampling method. Personal information form prepared by the researchers, “Leisure Management Scale (LMS)” and “Test Anxiety Inventory (TAI)” were used as data collection tools. In the analysis of the data, descriptive statistics, t-Test and Pearson Correlation analyzes were used by using SPSS 26.0 program. Results: There was no significant difference in the sub-dimensions of the leisure management scale and the total score averages according to the gender variable, while a significant difference was found in the TAI "delusional", "affective" sub-dimensions and total score averages. According to the family income variable of university students, a low-level and negative significant relationship was found in the "leisure attitude" sub-dimension of LMS, and in the total TAI and "delusional sub-dimension". A significant relationship was found between the age variable and the "goal setting and method" sub-dimension of LMS. A low and negative significant relationship was found between leisure and "goal setting and method", "leisure attitude" and total LMS score averages. In addition, while there was no significant relationship between LMS and TAI, it was found that there was a low and negative significant relationship between the "leisure attitude" sub-dimension and the test anxiety inventory and its sub-dimensions. Conclusion: It can be said that as the level of attitude towards leisure activities of university students’ increases, the feeling of exam anxiety may decrease, and the increase in free time will adversely affect the level of leisure management and attitude. Keywords: University students, Leisure management, Exam anxiety level. *It was presented as an oral presentation at the 5th Academic Sports Research Congress

Gardner’s (1983) Multiple Intelligences Theory (MIT) has been found to have profound implications in teaching English as a foreign language (TEFL) in that it provides a way for teachers to recognize learners’ individual cognitive and affective differences by providing favorable motivational conditions for learning. However, little investigation has focused on the domains of cognition and affect in a single study. Therefore, this study investigates two facets: the relationship of Multiple Intelligences (MIs) with listening among Iranian TEFL university students and the possible relationship between the type of intelligence the students fall into and their attitudes toward learning English. In this study, McKenzie’s (1999) MI Inventory was used to identify 60 participants’ preferred intelligences. The participants comprised an intact group randomly assigned to the experiment. A Likert-type questionnaire was employed to elicit data about participants’ levels of personality traits that accounted for their attitudes to language-learning. Also, the participants’ listening comprehension proficiency was measured using the listening section of a retired TOEFL test. Data analysis using Pearson correlation revealed no significant relationship between the score of listening and any of the MIs. Similarly, the results indicated no significant difference between MIs and attitudes.

Abstract Introduction: COVID-19, an illness caused by the novel coronavirus usually presents as a mild to moderate flu like illness, but can lead to pneumonia, acute respiratory distress syndrome and death in some patients. Since the onset of the COVID-19 pandemic there has been special attention towards patients with diabetes. Not only is diabetes highly prevalent in patients with COVID-19, but diabetes has been reported as a significant predictor of morbidity and mortality. Furthermore, race seems to be a predictor of severity with black people dying at 2.3 times the rate of white people. Methods: Here we performed a retrospective study of 524 cases of COVID-19 at an academic center in Chicago between March 2020 until August 2020. Data were obtained from patients that consented to the study to examine the relationship between diabetes, BMI, age, and race with degree of COVID-19 severity. Not all patients had all clinical and demographic data available. COVID-19 severity was determined using a severity index obtained from the measured SpO2 divided by the FiO2/fraction of inspired oxygen times 100. Numbers ≥ 315 mmHg were defined as low severity with patients generally requiring outpatient care, while 235–314 mm Hg were classified as moderate severity generally requiring inpatient care and≤ 234 mm Hg indicated high severity generally requiring intubation/ICU care. The Pearson correlation coefficient was used for linear correlation analyses. Proportion for categorical values were compared using the Chi squared test, the means for continuous variables were compared using two-tailed t tests or one way ANOVA (with Tukey post-test) for comparisons involving more than two conditions. A multiple linear regression model was used to assess the contribution of different variables. Differences were considered statistically significant at p&lt;0.05 Results: Among 120 patients with an A1c, 55 (46%) patients had diabetes and 65 (54%) did not have diabetes. More patients with a high severity index were seen in the cohort with diabetes compared to those without diabetes (72% compared to 28% p=0.004). Univariate analyses revealed statistically significant positive correlations with higher COVID-19 severity and older age, BMI, and African American race. ANOVA analysis revealed a statistically significant difference between increasing BMI and worse severity category with a BMI mean of 29.3 kg/m2 in the low severity category compared to 34.9 kg/m2 in the moderate severity category (p=0.006). A multi-variate analysis adjusting for all variables revealed that A1c, older age and race were positively associated with higher COVID-19 severity. Conclusion: Increased A1c, older age and race are positively and independently associated with a higher COVID-19 severity index. Further research regarding the relationship between COVID-19 and these associations is urgently needed.

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.
