Effect of Multitasking on Simulator Sickness and Performance in 3D Aerodrome Control Training
No full text Background. Air traffic controllers need to use their cognitive resources to cope with multiple tasks while monitoring air traffic. They are trained through advanced 3D simulators; however, they might demonstrate simulator sickness symptoms during this training. The relationship between multitasking and simulator sickness and the influence of different tasks on these variables can be investigated to inform further training practices for an efficient traffic monitoring. Purpose. The purpose of this quasi-experimental research was to explore the influence of different working positions and multitasking scenarios on simulator sickness and performance in 3D Aerodrome Control Training. Method. Thirteen undergraduate students from a civil aviation school participated in a time-series experimental design. Nausea, disorientation and oculomotor disturbances were measured before and after conducting different multitasking scenarios in an aerodrome control simulator. A 20-item simulation performance scale was also used. Performance differences and the relationship between simulator sickness and performance were addressed through parametric tests. Results. Findings revealed that tower-ground positions created higher levels of nausea. Performance scores varied in different scenarios. Simulator sickness was higher in females. Total sickness correlated negatively with performance in all scenarios. Conclusion. Certain tasks have different influences on both simulator sickness and performance. Concurrent multitasking seems to trigger simulator sickness further. The degree of simulator adaptation, test anxiety and physiological measures of the process should be considered in further research. </jats:p
Effect of Different Multitasking Scenarios Realized in Different Physical Settings on Cognitive Load and Achievement
No full text8th International Conference on Education and New Learning Technologies (EDULEARN) -- JUL 04-06, 2016 -- Barcelona, SPAINWOS: 000402955906137This study aimed to investigate the effect of different multitasking scenarios realized in different physical settings on cognitive load and retention. It also aimed to investigate the influence of multitasking and physical settings on cognitive load when the working memory capacity is controlled. In addition, the measurement of cognitive load is realized through both objective (electroencephalography) and subjective measures (cognitive load scale). Subjects were undergraduate students at a state university.Scientific and Technological Research Council of Turkey (TUBITAK) [115K773]; Anadolu University Research Fund [1505E366]This study contains preliminary findings of the first author's Ph.D. proposal, which is supervised by the second author.

DAPNet++: density adaptive PointNet + + for airborne laser scanning data
No full textAddressing the challenges arising from the irregularity and varying density of Airborne Laser Scanning (ALS) point clouds, which particularly affect the performance and generalization ability of 3D Deep Neural Networks (DNNs), is essential for their effective application in direct semantic segmentation tasks. In this study, we investigated the underexplored aspect of adapting PointNet + + for semantic segmentation of ALS point clouds. We introduced Density-Adaptive PointNet++ (DAPNet++) to enhance robustness against variable point densities through modifications made to the original PointNet + + architecture. Our methodology includes controlled block partitioning based on point density replacing the original batching strategy. Another key advancement in the study is the automation of the initial value of the neighborhood search radius by taking into account the characteristics of the dataset. This approach optimizes receptive field determination, crucial for effective semantic segmentation. The effectiveness of DAPNet + + is validated through extensive experiments on various datasets, including ISPRS Vaihingen, DALES, subsampled DALES, and OpenGF. Notable improvements include up to 11% increase in weighted mean Intersection-over-Union (mIoU) on the highly variable OpenGF test dataset and 3% increase in mIoU on the subsampled DALES dataset. Furthermore, the generalization capability of the DAPNet + + was tested, revealing an approximately 5% improvement in evaluation metrics compared to PointNet++. In summary, DAPNet + + minimizes trial-and-error in the selection of parameters for block partitioning and radius, and it enhances robustness against variable point density. With the proposed approach, it has been observed that there is a significant improvement in accuracy for underrepresented classes, mitigating class imbalance in ALS point clouds. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024
Predictors of inconsistent responding in web surveys
No full textWOS: 000351293000007Purpose - The purpose of this paper is to investigate the antecedents of inconsistent responding in web surveys. Consistency of responses to personal information questions and scale items were compared, and the influence of perceived social support, social appearance anxiety, academic self-efficacy and social networking habits on inconsistent responding was examined. Design/methodology/approach - A gaming application on Facebook was used to collect data. A repeated-measures design was conducted with 806 respondents in two online survey administrations. After inconsistent responses provided by the same nicknames were identified, consistent and inconsistent respondents were compared with regard to their responding patterns and research variables. Findings - Findings revealed that 45.7 percent of participants misreported their personal information such as age, educational status and gender. Participants were relatively consistent in their responses to attitude scales. Perceived social support led to inconsistent responding whereas social appearance anxiety and academic self-efficacy was not influential in response patterns. A binary logistic regression revealed that perceived family support, number of Facebook friends and Facebook use duration successfully distinguished inconsistent respondents from consistent respondents. Research limitations/implications - The sample frame has several limitations insofar as the study only addressed a unique gaming application on Facebook. Thus, unique interactive characteristics of the current context may have altered the nature of responding. Practical implications - Practitioners should not rely on the personal information provided by online survey respondents to conduct parametric tests, whereas responses to online attitude scales seemed relatively consistent. Originality/value - The principal contribution of the paper is that findings have provided insights into the current status of response patterns in online survey administrations. In addition, the paper highlights the importance of individual variables which influence the consistency of responses.Anadolu University [1306E257]The author would like to thank the Editor and reviewers for their contributive comments.

Effects of multitasking on retention and topic interest
No full textWOS: 000366341900010A recent and pervasive "urban legend" in education describes contemporary students as digital natives and effective multitaskers. The current study investigated the effects of sequential and concurrent multitasking scenarios on content retention and topic interest in a multimedia learning environment. Five hundred and seventy two undergraduate students were randomly assigned to one of the seven conditions in which either sequential or concurrent multitasking scenarios were simulated through a web-based system. While the sequential conditions either required switching between instructional and distractive videos or between two instructional videos, the concurrent multitasking scenarios involved online chatting while watching the videos. The relationships between digital device experience, daily media exposure, current multitasking habits, working memory components, and content retention were also investigated. Findings revealed that sequential multitasking did not interfere with retention whereas concurrent multitasking interfered with both retention and topic interest. Digital device experience and daily multitasking habits were not related with retention. Furthermore, daily media exposure was negatively associated with the retention, particularly in the longer sequential multitasking scenarios. Finally, different types of multitasking were related with different working memory constructsScientific and Technological Research Council of Turkey (TUBITAK) [114K633]This study is the summary of the first author's PhD dissertation, which is supervised by the second author and financially supported by the Scientific and Technological Research Council of Turkey (TUBITAK grant ID: 114K633)

Crimean war on its 160th anniversary
No full textAkbulut, İlhan (Dogus Author)Kırım Savaşı, Osmanlı Padişahı Abdülmecid zamanında Osmanlı, İngiliz ve Fransız devletlerinin Rusya’ya karşı yaptıkları savaş olarak anılır. Sultan Abdülmecid’in Osmanlı İmparatorluğu’nu yeniden güçlü duruma getirmek amacıyla başlattığı reformlar, Rusya Çarlığını memnun etmemişti. Zira Rus Çarı Nikolay I kendini “Hasta Adam” Osmanlı İmparatorluğu’nun varisi olarak görüyordu. Bu yüzden, Osmanlı İmparatorluğiçindeki bütün Ortodoksların himayesine verilmesini istedi. Padişahın reddi üzerine Eflak-Boğdan eyaletlerini işgal etti. Osmanlı Devleti ise Katolik Avrupa Devletlerinin de konuya taraf olmalarını ve böylece bir denge oluşturmayı öngören bir siyaset belirlemekte gecikmedi. Bu siyaset, Avrupa’nın desteğini alabilmenin bir koşulu olan “Tanzimat Fermanı”nın ilânından sonra adım adım başarıya ulaştı. İngiltere ve Fransa ise, Kutsal Yerler’de kapitülasyonlarla kazandıkları imtiyazları kaybetmek istemediklerinden Osmanlı İmparatorluğu’nun yanında yer aldılar.Crimean War is known as the war held by British and French armies against the Russian Government in the reign of Ottoman Sultan Abdülmecit. The Russian Tsardom was not happy with the reforms made by Abdülmecit to regain the strength of Ottoman Empire. For Russian Tsar Nikolaj The First was seeing himself as the successor of Ottoman Empire the “sick man”. For this reason he wanted all the Orthodox people to be given to his protection. Upon refusal of Ottoman Padishah, he occupied Eflak-Bogdan States. Thus, Ottoman Empire immediately determined apolicy that anticipate the participation of the Catholic European Governments with an intention of maintain a balance. This policy had been successful step by step after the announcement of Administrative Reforms (Tanzimat Fermanı), which was the only condition to get the support of the European Governments. Britain and France stood beside Ottoman Empire since they did not want to loose the privileges that they gained by the capitulations
Globalization and justification of war in international media discourse: a comparative study of media discourses between the 1st and the 2nd Gulf Wars
No full textFor decades globalization has had enormous implications on almost every dimension of life. In examining these implications, this research addresses the relationship between globalization and international media discourse through the topic of justification of war. Accepting media as a tool of soft power, it attempts to study the function of media on people’s perception of realities. Based on this foundation, it aims to understand how soft power is composed and maintained through media in the new form of international affairs. More specifically this research first compares and contrasts the international media discourse on the two Gulf Wars through a two step framing analysis. Then, it contrasts the results with the Turkish national media discourse of war justification to see the impacts of international media discourse on national media. Finally, it provides an evaluation of findings in relation to the globalization literature, reveals the implications of the findings in terms of the use of soft power, and make recommendations for policy makers and researchers. The results of the analysis prove the diffusion in international media discourse. According to findings, the 1st Gulf War was presented by only one news channel, CNN, with a hard pro-American discourse, while the 2nd Gulf War is presented by multiple news channels representing the both sides of the war. Reflections in the Turkish news media confirm the same stances with international media for both wars. In the 1st War, the unavailability of alternative news sources provided CNN with the ability to operate freely and basically control the international media domain. It gave a strong voice to the causes and successes of American policy, while offering very little perspective from to other views. In the 2nd Gulf War, however, diffusion in the discourse revealed the removal of a superpower monopoly on communication technologies and the emergence of alternative views in international media. The diffusion had enormous implications in terms of the use of soft power. It renders conventional tools and strategies obsolete, and requires new ones in terms of maintaining soft power due to newfound critical challenges.Ph.D.Includes bibliographical referencesIncludes vitaby Ayhan Akbulu
