Item Effects of Repair Techniques and Scarf Angles on Mechanical Performance of Composite Materials(2023) Karaduman, Beyza Naz; Elaldi, Faruk; https://orcid.org/0000-0003-0592-6868; AAG-5060-2019Today, composite materials, which have the advantage of strength and lightness ratio, have gained great importance especially in the aeronautical industry and automotive sector. With widespread use of composites, the repair of damages caused by external factors has also become an important research topic. In this study, the effects of different repair methods and scarf angles on the mechanical performance of the material were investigated. Scarf angles of 20 degrees, 30 degrees, and 45 degrees have been selected in order not to create too many scarf areas and to find a quick repair method. Also, a comparison of single scarf and double scarf repair was made to find a more robust solution. The samples were produced from carbon fiber prepreg and with the [45/0/90/0/45](2s) fiber orientation. Tensile, compression, and flexural (3-point bending) tests according to ASTM standards were applied to composite samples prepared with single scarf and double scarf repair configurations at different angles. The stress-strain curves obtained as a result of the tests showed that the specimens repaired at 20 degrees had the highest strength. In addition, it has been determined that the samples repaired with double scarf withstand higher forces compared to the samples repaired with single scarf at the same angle.Item In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries(2022) Sarioguz, Eyluel; Karaarslan, Cemre; 36185503The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these steps, you can endanger yourself and others") or potential gains (e.g., "If you practice these steps, you can protect yourself and others")? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message framing on COVID-19-related judgments, intentions, and feelings. Loss- (vs. gain-) framed messages increased self-reported anxiety among participants cross-nationally with little-to-no impact on policy attitudes, behavioral intentions, or information seeking relevant to pandemic risks. These results were consistent across 84 countries, three variations of the message framing wording, and 560 data processing and analytic choices. Thus, results provide an empirical answer to a global communication question and highlight the emotional toll of loss-framed messages. Critically, this work demonstrates the importance of considering unintended affective consequences when evaluating nudge-style interventions.Item Teacher Competencies for Differentiated Instruction Approach(2022) Zoraloglu, Saadet; Sahin, Ali EkberDifferentiated instruction is an approach ensuring the fairness in education. Therefore, it is a professional responsibility of teachers to differentiate the instruction. In this study, it is aimed to specify the competencies for the differentiated instruction approach. In compliance with the nature and context of the research question, the method of examination of the relevant field literature was chosen to specify the competencies. In this research, document analysis method, one of the qualitative approaches, was used. The data source of the study consist of peer reviewed publications and basic reference books related to the differentiated instruction approach. Competencies specified through the analysis of the data sources are grouped under the certain themes along with their findings. Subsequently, competencies were finalized by taking the expert opinions. As a result of the research, 39 teacher competencies were identified under the three competency area; knowledge, skill and belief. In line with the use of the identified competencies, suggestions for research and practice were made.Item How To Improve The Quality Of Online Education From Online Education Directors' Perspectives(2022) Akbaba Altun, Sadegul; Johnson, Tristan E.COVID-19 pandemic showed once again the need for quality in online education all over the world. The aim of this research is to solicit how to improve the quality of online education from online education program directors' perspectives. The research was designed as a qualitative case study. Eight participants who were responsible for directing, managing, supervising and organizing online education programs participated to this study. The data were collected through interviews and were analyzed through content analysis. Eight dimensions were found to improve the quality of online education. These dimensions were focusing on students' needs; focusing on change in education; focusing on system as a whole; focusing on leadership; focusing on continuous improvement of online education; focusing on integrating learning and teaching theories into online education; focusing on research about online education; and focusing on quality of instructors.Item Parents' Shares On Instagram In The Early Days Of The COVID-19 Pandemic(2022) Er, Suhendan; Yilmazturk, Nergis Hazal; Ozgul, Tuba; Cok, FigenMany people had to stay at home with their families during the pandemic because of social distancing guidelines and lockdowns. This study aims to explore the content of 'sharenting' of parents during the early COVID-19 pandemic and quarantine periods in Turkey. In total, 401 posts were collected from public Instagram accounts of parents who shared their own children's photos or videos between 18th30th April 2020, via the most commonly used hashtags of #korona (#corona) and #evdekal (# stayhome). Descriptive content analysis was conducted within identified categories. Results revealed that the popular hashtag #stayathome is particularly important for its optimistic representation of the lockdown process in society. Content analysis results show that with the inclusion of social media shares, family members spent more time together, which can be seen as one of the positive consequences of this period. In the results of continued sharenting during the early pandemic, children's faces were mainly kept visible, which might concern children's privacy. Additionally, mothers shared more during this period. Consequently, education to increase awareness of such concepts gains importance, especially for the well-being and privacy of children and any future implications.Item Effectiveness Of Negative-Pressure Wound Therapy Compared To Wet-Dry Dressing In Pressure Injuries(2022) Sahin, Ezgi; Rizalar, Selda; Ozker, Emre; 35022147This study aims to compare the effects of Negative-Pressure Wound Therapy (NPWT) and wet-to-dry dressing on Stages 3 and 4 pressure injuries (PI), This study is a randomized controlled trial. A total of 30 patients with Stages 3 and 4 pressure injuries were included in the study. The patients were divided into two groups: NPWT group and the wet-to-dry dressing group. All patients received 3 rounds of treatment. Data were collected with a Patient Identification Form, Pressure Ulcer Scale for Healing (PUSH) Tool and the findings of the Three-Dimensional Wound Measurement (3DWM) device. We found that granulation tissue formation was more significant in the experimental group (p < .05), and that there was more significant wound shrinkage (p < .05) with a more significant decrease in the PUSH Tool scores (p < .05). The wounds were assessed with the tool and the 3DWM system. Device measurements were found to be correlated with PUSH Tool findings (p < .05). There was a significant correlation between device-measured granulation findings and PUSH Tool score results of the experimental group's third measurements (p < .05). We conclude that NPWT is an effective treatment method for pressure injuries, and 3DWM device is a useable wound assessment tool.Item A Snapshot Of Flipped Instruction In English Language Teaching In Turkiye: A Systematic Review(2022) Baltaci, Hasan SerifThis study aims to explore the trends and the perceived benefits and challenges of flipped language instruction regarding student achievement and attitudes in Turkiye. To that end, the databases, including Web of Science Core Collection, Scopus, Eric and DergiPark were reviewed, and a total of 20 articles were analyzed. Systematic review was utilized as the research methodology. The findings revealed that flipped instruction in ELT has gained importance since 2015 in Turkiye and has been gradually receiving more attention in research and practice. In the reviewed studies, the most employed research method turned out to be the mixed method, whilst the purely quantitative and qualitative studies were not abundant. It is seen that writing has been the most frequently researched language skill with respect to flipped instruction, whereas the other skills were not subject to investigation considerably. Furthermore, apart from language skills as the primary focus, the studies also concentrated on students' perceptions, achievement, self-directed learning, attitudes, and classroom engagement. Finally, the reviewed studies illustrated the challenges and benefits of the flipped classroom in relation to students' achievement and attitudes towards learning. In the light of the findings, implications for practice and recommendations for future research are provided.Item Validity and Reliability Testing Study of the Turkish Version of the Misophonia Scale(2022) Sakarya, Merve Deniz; Cakmak, EdaMisophonia is a disorder where individuals experience decreased tolerance to certain sounds that trigger intense emotional or physiological responses in them. People with misophonia can feel disgust, anger, anxiety, and they may experience anger outbursts when exposed to certain sounds that are insignificant to other people, such as chewing, lip-smacking, and breathing. There is no consensus on the prevalence, assessment, and management of misophonia. A major barrier to the research on misophonia is the lack of robust psychometric assessment tools. This study aims to meet the need for a measurement tool for clinical and population-based evaluations intended for misophonia by adapting the Misophonia Questionnaire (Wu et al., 2014) to Turkish. The research was carried out on 638 undergraduate students at Baskent University, from 18 to 26 years of age. Exploratory factor analysis was conducted on 420 participants (73% female, 27% male) and confirmatory factor analysis was conducted on 218 participants (62% female, 38% male). The statistical reliability was evaluated using the internal consistency coefficient, split half, and test-retest methods. In the Misophonia Questionnaire, misophonia was explained by the following three subscale factors: misophonia symptoms, misophonia emotions and behaviors-avoidance and internalization, and misophonia emotions and behaviors-aggression and externalization. These were used in the exploratory factor analysis. The confirmatory factor analysis found that the fit indexes were within acceptable limits. With the discriminant validity, the participants with clinical misophonia were observed to have a higher mean in all factors than those without. The internal consistency coefficient of the scale was calculated at .89, and for the three subscale factors mentioned earlier were .79, .85, and .83, respectively. The calculated test-retest reliability coefficient was .78, which applied to 75 participants. The split-half reliability coefficient was .83 (for each subscale factor, was .86, .87, and .81, respectively). With this study, the Misophonia Questionnaire, which can be used to evaluate misophonia in the general population, was adapted into Turkish. From the psychometric analysis, data supporting the validity and reliability of the Misophonia Scale were obtained.Item Compliance with Long-Term Use of Orthoses Following Spinal Cord Injury(2022) Yemisci, Oya U.; Ozen, Selin; Cosar, Sacide N. Saracgil; Afsar, Sevgi, I; 35532629Background: Prescription of orthoses and assistive devices that facilitate physical function is a major component of the rehabilitation process in spinal cord injury (SCI). Objective: To evaluate the long-term use of orthoses prescribed during inpatient rehabilitation in people with SCI and investigate the factors related to discarding the device. Materials and Methods: Medical records of 202 SCI patients who were included in an inpatient rehabilitation program of a tertiary research hospital were reviewed retrospectively. Patients' demographic data, neurological level of spinal cord injury functional state and use of assistive devices for ambulation (orthoses, walkers, etc.) at discharge were recorded. At follow-up, study participants were contacted by telephone and queried regarding the frequency and duration of use of orthoses; if the individual had discontinued using the orthoses, the reasons for discarding the device were sought. Results: The majority of the study participants (62.7%) had been prescribed a knee-ankle-foot orthosis during their inpatient stay. At follow-up, the regular use of orthoses was ongoing in 67.6% of the participants, and nonuse was determined in 32.4%. The most common cited reasons for discarding the device were difficulty in donning and doffing, functional improvement, and mechanical problems of the orthoses. Conclusions: A significant number of patients had discarded their orthoses at the long-term follow-up and the main reasons for discarding the devices were orthotic factors. Timely reevaluation of the patient and orthosis modification according to patients' needs is necessary to achieve long-term compliance.Item Transcultural Memory of the Nation in Caryl Phillips's A Distant Shore(2022) Kirpikli, Deniz; https://orcid.org/0000-0002-0330-593XThis study argues that Caryl Phillips's A Distant Shore (2003) uncovers Britain's transcultural memory of the imperial past through the journey of the refugee protagonist Solomon/Gabriel from Africa to England. The unlikely encounter between Solomon/Gabriel and Dorothy, a white Englishwoman, in a setting inhospitable to both of them opens up a narrative space to explore the imperial legacy that persists in contemporary racism in Britain. The novel achieves this through a mnemonic narrative strategy based on a fragmented structure with a narrative voice shifting back and forth in time and place. In doing so, the novel contests the idea of the homogeneous nation by drawing parallels between the Middle Passage and refugee flow from Africa. This study will, thus, demonstrate that the novel offers a transcultural perspective on memory and nation by illustrating the cross-border reach of memories that are ignored by national essentialism.
