Effect of Mobile Instructional Design on Student Perception of Distance Learning

Learning through mobile applications has become more relevant as mobile tools have evolved. The COVID-19 outbreak that spread across the globe in 2019 promoted to a brief period of distance learning. The purpose of the study was to investigate how the students' perceptions of distance learning were affected by the use of a mobile application designed for a seventh-grade mathematics course. The research was performed using quasi-experimental design. The study was conducted in the distance education process with 7th grade students studying in a secondary school in the 2020-2021 academic year. The mobile application was used to deliver the instruction to the students in the experimental group, whereas the control group received instruction based on the textbook. To collect the data for the study, Yıldırım et al. (2014) designed the "Student Opinions Scale for Distance Education". T-tests were used to assess the data for dependent and independent samples, respectively. The study revealed a substantial difference in the post-test results of the students in the experimental and control groups. It was discovered that there was no significant difference between the pre and posttest scores of the control group students' opinions on distance education and that there was a substantial increase in the experimental group students' attitudes on distance education between the two assessments. According to the findings, it has been suggested that by creating mobile applications in various ways and including them into the distance learning process, the impacts of using them for mathematics classes on distance learning can be studied

Response styles and avoidance strategies in bipolar disorder and healthy controls: A comparative study

Objective: This study aimed to investigate stress appraisals, rumination, worry, and experiential avoidance (EA) in patients with bipolar disorder-I (BD-I) in the euthymic phase of the illness. The effects of these processes on functionality in individuals with BD-I a re also investigated. Method: Using the Stress Appraisal Measure Dispositional Form (SAM-D), Ruminative Thinking Style Questionnaire (RTSQ), Penn State Worry Questionnaire (PSWQ), and Acceptance and Action Questionnaire-II (AAQ-II), we compared 67 BD-I patients with 70 healthy controls. Additionally, multiple linear regression analysis was used to determine the predictors of functionality levels measured by the Bipolar Disorder Functioning Questionnaire (BDFQ). Results: BD-I group showed significantly higher SAM-D "threat," "uncontrollable by anyone," and "control by others" scores. The BD-I group also reported higher EA (AAQ-II) than the control group. Rumination (RTSQ) and worry (PSWQ) did not show any significant differences between groups. BDFQ was negatively predicted "uncontrollable by anyone" and positively predicted by "control by others" subdimensions of SAM-D. Conclusion: Our findings suggested that patients with BD-I have differences in stress appraisals, even in the euthymic phase. Higher AAQ-II scores seemed to be a distinctive feature for patients with BD-I that may be related to perceiving stressful situations as threatening and uncontrollable. Our results present new perspectives for psychotherapeutic interventions both for the treatment and for the improvement of the functioning of these patients

Investigation of emotional schemas between adolescents and their mothers

Objective: It is common to see that child-parent interaction affects psychological problems in adulthood. This interaction process may also be effective in developing emotional schemas and attitudes. The present study aimed to investigate the similarities or differences in emotional schemas between mothers and adolescents in both clinical and control groups.Method: Eighty-two adolescents who applied to the child and adolescent outpatient clinics and their mothers (assigned as the clinical group) and 80 adolescents without any psychiatric problems and their mothers (assigned as the control group) were examined using a Sociodemographic Characteristics Form and Leahy Emotional Schema Scale Turkish Version (LESS-T). A multivariate analysis of variance test was used to determine the intergroup differences in emotional schema levels.Results: LESS-T was applied to all participants. No statistically significant difference was found between mothers and their adolescents on the LESS-T subscales in the control group (p=0.89). Mothers in the clinical group reported higher levels of demand for rationality (p=0.003) and emotional avoidance (p=0.01) than mothers in the control group. In the clinical group, adolescents reported higher levels of uncontrollability (p=0.007), and mothers reported higher levels of comprehensibility (p=0.001), demand for rationality (p=0.001), and emotional avoidance (p=0.007).Conclusion: Mothers' emotional schemas, such as avoidance and demand for rationality, may prevent their children from expressing and experiencing emotions sufficiently. Findings emphasize the importance of healthy mother-child interaction for developing emotional skills

Petrolgy of the volcanic/subvolcanic members of the volcanosedimentary Maden Complex in Eastern Turkey

Maden Complex exposed in Eastern Turkey, is a succession of volcano-sedimentary rocks and tectonically overlain by Bitlis Metamorphics and Cretaceous ophiolitic rocks. The succession includes shallow-water deposits and deep marine pelagic sediments intercalated with pillow lavas ranging from a few centimeters to ten meters in diameter. The planktonic foraminiferal assemblages from micritic limestones and zircon U-Pb ages from selected sedimentary rocks indicate the age of Late Ypresian - Early Lutetian. Plagioclase and clinopyroxenes are the main mineral phases, olivine rarely found as altered phenocrysts. Clinopyroxenes are augite and diopside, and their compositions are ranging between Wo44-51, En27-43, Fe10-21. The anorthite contents of plagioclases are between 32- 67 % in unaltered grains. The crystallization temperatures and pressures obtained from clinopyroxene chemistry are ranging from 1126 to 1250oC and 3 to 8 Kbar, respectively. The majority of the volcanic/subvolcanic rocks are subalkaline-tholeiitic basalts however; a few andesitic and rhyolitic derivatives are also present. The whole – rock and Sr-Nd-Pb isotope compositions reveal that the basaltic rocks are originated from E-MORB like asthenospheric mantle source without a subduction component

Ramelteon Protects Intestinal Tissue Against Injury Caused by Methotrexate Via Showing Anti-apoptotic, Antiinflammatory and Antioxidant Properties

Objective:Methotrexate (MTX), a drug used in the treatment of autoimmune diseases and cancers, is a folic acid antagonist, but it has toxic effects on the gastrointestinal system (GIS). In this study, we examined the anti-inflammatory, antioxidant and anti-apoptotic effects of Ramelteon (RAM), a melatonin receptor agonist, on the MTX-induced toxicity in the intestinal tissue of rats.Methods:Thirty-two male Wistar albino rats were randomly divided into 4 groups; Control group, MTX group, MTX + RAM group, and RAM group. Single-dose 0.1 mL 20 mg/kg MTX, saline or 0.1 mL 10 mg/kg RAM orally was administered for 7 days. Animals were sacrificed at the end of 7 days after the last drug administration. Then, intestinal tissues were collected for biochemical, histopathological and immunohistochemical analyses.Results:While normal histological findings and biochemical parameters were observed in the control and RAM groups, in the MTX group, mononuclear cell infiltrations, hemorrhagic areas, degenerations in the submucosa and Lieberkuhn crypts were observed in the intestinal sections. Caspase-3 (Cas-3) and tumor necrosis factor-alpha (TNF-α) expressions, total oxidant status (TOS) and oxidative stress index (OSI) increased and total antioxidant status (TAS) decreased in the MTX group. RAM treatment decreased Cas-3 and TNF-α expressions, TOS, OSI levels and increased TAS levels.Conclusion:In this study, RAM showed anti-apoptotic, antioxidant and anti-inflammatory effects on MTX-induced toxicity in intestinal tissue. Therefore, it was suggested that RAM might be used in MTX-like toxicities to alleviate the side effects on the GIS
