Yayın Are the crypto markets shock resilient to COVID-19? A comparative investigation of trading prices and volumes(Econometric Research Association, 2025) Khan, Asad ul Islam; Bwando, William; Yönetim Bilimleri Fakültesi, İktisat BölümüThe emergence of crypto currency as an alternative source of currency has been dubbed as one of the greatest phenomenon of the 21st century. Over the years, crypto currencies have grossly interrupted the traditional financial system and they continue to act as a catalyst for its revolution. However, cryptocurrencies have not been free from misery and controversies. The aim of this study is to explore and investigate empirically the impact of Covid-19 pandemic on price and volume dynamics in crypto markets. The study makes use of two data samples, but these samples are analyzed separately and independently. The first sample consists of Top Five Cryptocurrencies in terms of market capitalization (Bitcoin, Ethereum, XRP, Binance coin and Litecoin) as at 7 November 2020. The second one is made up of the Bottom Five Cryptocurrencies among the top 40 cryptocurrencies (FTX Token, Huobi Token, Filecoin, Dash and Decreed) as at 7 November 2020 again. The data among the Top Five Cryptocurrencies ranges from 2014 to 2021 and the data among the Bottom Five Cryptocurrencies ranges from 2018 to 2021.. The empirical results reveal that all crypto-currencies are integrated at order 1 i.e. I (1). The empirical analysis confirms presence of strong evidence for intra-and-inter long run relationship between price and volume dynamics within the crypto market irrespective of whether it is pre-pandemic or pandemic period. More so, there is convincing evidence from the results that much of the variance among the prices and volumes of the top five cryptocurrencies is attributed to the Bitcoin price-volume dynamics. This implies that it is critical for crypto market traders, investors and portfolio managers, before making any investment decision must consider the dynamics of price and trading volumes of BITCOIN as they hugely impact the prices and volumes of other altcoins.Yayın Building brand loyalty through digital marketing: Insights from young airline travelers(Busssecon International Academy, 2025) Ali, Fatima; Hacıoğlu, Ümit; Zehir, Melike; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study explores the influence of digital marketing strategies on brand loyalty among young airline passengers, specifically targeting Millennials and Gen Z individuals aged 18-35 years old. With the increasing reliance on digital channels such as social media, email marketing, and search engine marketing, it is crucial to understand how these strategies impact the customer-brand relationship, brand trust, and ultimately, brand loyalty. The research employs a quantitative approach, gathering data from 230 participants who are frequent users of digital platforms and have recent travel experiences with airlines. The findings reveal that social media marketing has the most significant impact on the customer-brand relationship, followed by email and search engine marketing. Additionally, the study confirms that brand trust acts as a critical mediator between digital marketing activities and brand loyalty. These results highlight the importance of tailored digital marketing strategies for airlines aiming to engage and retain young passengers in a highly competitive industry.Yayın Two sides of the same coin? A comparison between internet-based and paper-based data collection for autism quotient and depression, anxiety and stress scale(Cambridge University Press, 2024) Sönmez, Dilruba; Abidi, Yousr; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji BölümüThe utilization of internet-based data collection in mental health research has gained popularity for its convenience and affordability. However, concerns often arise regarding the validity and reliability of data collected via the internet. The Autism Spectrum Quotient (AQ) is a self-report questionnaire to measure the traits associated with autism spectrum disorder (Baron-Cohen et al. J Autism Dev Disord, 2001; 31 5-17) and the online usage of AQis common and conducted with large numbers of participants across many studies. However, the effect of using internet-based data collection for AQ rather than conventional paper-based procedures is unknown.Yayın Interpersonal emotion regulation strategies and social problem solving skills: How do they interact in the prediction of psychological distress in adolescents?(European Association for Developmental Psychology/ Development trends: Concerns and opportunities, 2021) Söğüt Kahramanlar, Meryem; Yedidağ, Ecem; Ray Yol, Elçin; Özdemir, Berk; Altan Atalay, Ayşe[No Abstract Available]Yayın The association of numeracy skills with Penn Conditional Exclusion Test performance of 5 to 8 year old Turkish children(European Association for Developmental Psychology/ Development trends: Concerns and opportunities, 2021) Söğüt Kahramanlar, Meryem; Göksun, Tilbe[No Abstract Available]Yayın Examining the influence of situational factors on reappraisal efficiency among Turkish adult participants: An exploratory study(Serbian Association for Cognitive and Behavioural Therapies, 2024) Söğüt Kahramanlar, Meryem; Uysal, Burcu; Altan Atalay, Ayşe; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji BölümüBackground and Purpose Emotion regulation (ER) encompasses the processes we utilize to influence our emotions. Among ER strategies, cognitive reappraisal (CR) is notably effective, as emotions often stem from appraisals of events. Frequent CR use correlates with positive outcomes like reduced negative emotions, stronger social connections, higher academic achievement, enhanced psychological well-being, and fewer psychopathological symptoms. Despite existing research, gaps remain in characterizing different reappraisal instances based on a theoretical framework and predicting their effectiveness across contexts. The reAppraisal Framework distinguishes between two different reappraisal mechanisms to shift appraisal: reconstrual (changing situation interpretation) and repurposing (changing the goal which the interpretation is compared to). Given that reappraisal is not a unified strategy and its effectiveness varies depending on contextual factors such as controllability of the stressor, this study aimed to examine: a) the role of appraisal dimensions in determining the type of emotion experienced (sadness or anxiety), and b) the effectiveness of reconstrual and repurposing in reducing short-term emotions (sadness and anxiety) depending on perceived control (low/high)…Yayın PTSD among Turkish earthquake survivors: The role of cognitive distortions and religious coping(Serbian Association for Cognitive and Behavioural Therapies, 2024) Söğüt Kahramanlar, Meryem; Aytemür Mneımneh, İlknur; Akyüz, Elif; Furkan, Muhammed; Uysal, Burcu; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji BölümüBackground and Purpose In 2023, two major earthquakes of magnitudes 7.7 and 7.6 struck eleven cities in southern Turkey, affecting 13.5 million people. In addition to their devastating impact, earthquakes are known to have negative effects on people’s psychological health. Among the psychological issues faced by survivors, PTSD is the most common, with over 50% of survivors affected three months post-disaster in the 2023 Turkey earthquake. Chronic PTSD can lead to severe outcomes, such as substance misuse, isolation, cardiovascular issues, and suicidal tendencies. As a result, it is critical to examine the factors influencing PTSD following earthquakes in order to improve survivors’ physical and mental well-being...Yayın Problem orientation and psychological distress among adolescents: Do cognitive emotion regulation strategies mediate their relationship?(Sage Publications, 2022) Söğüt Kahramanlar, Meryem; Yedidağ, Ecem; Ray Yol, Elcin; Özdemir, Ahmet Berk; Altan Atalay, AyşeAdolescence is a critical period for the development of attitudes and skills crucial in determining vulnerability for psychological distress. The current study aimed to focus on the association of problem orientation and cognitive emotion regulation strategies with psychological distress and demonstrate the mediator roles of adaptive and maladaptive cognitive emotion regulation strategies in the association of problem orientation with psychological distress. Data were collected from 335 adolescents (167 female) aged 14-to-18 years (M= 14.7, SD= .95) via measures of problem orientation, cognitive emotion regulation, and psychological distress. The results revealed that maladaptive emotion regulation strategies (self-blame and other-blame) mediated the association of negative problem orientation with psychological distress. The findings emphasize the crucial roles of blaming-focused strategies in this relationship.Yayın A qualitative analysis of Eye Movement Desensitization and Reprocessing (EMDR) experiences for trauma(The Center for Educational Measurement and Evaluation, 2024) Zorlu, Ayşe Selin; Uysal, Burcu; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü[No Abstract Available]Yayın International response to humanitarian crisis: A study of Rohingya issue(İdeal Kültür Yayıncılık, 2020) Masood, Syed Muhammad Usman; Uddin, Muhammad Salah[No Abstract Available]Yayın Syrian refugees: Integration and challenges in Turkey(İdeal Kültür Yayıncılık, 2020) Moiz, Muhammad; Masood, Syed Muhammad Usman[No Abstract Available]Yayın Issues faced by Palestinian refugees in Jordan(İdeal Kültür Yayıncılık, 2020) Uddin, Muhammad Salah; Masood, Syed Muhammad Usman[No Abstract Available]Yayın Recent migrations to Uganda: Challenges and steps towards integration(İdeal Kültür Yayıncılık, 2020) Moiz, Muhammad[No Abstract Available]Yayın Industry 4.0 technologies revolutionizing the civil aviation sector: E-services technology adoption in aviation industry(Bussecon, 2025) Awe, Ya Neneh; Hacıoğlu, Ümit; Zehir, Melike; Yönetim Bilimleri Fakültesi, İşletme BölümüIndustry 4.0 technologies have optimized efficiency and effectiveness through the manufacture of sophisticated products and services, which result in enhancement of operations, improvement in safety, time, and cost-saving, and have revolutionized operations in almost all industries and have tremendously transformed the aviation sector. This study aims to examine the passenger travel experience with the implementation of e-services before, during, and after trips, from ticket bookings, self-check-in, smart boarding, in-flight services to baggage tracking after flight. Furthermore, the study seeks to identify the modern technologies with which air passengers are familiar or actively use, and to analyze the factors that influence their acceptance of these e-services. A research model was developed based on the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) and modified to suit the objectives of this study. The study objectives were achieved through a survey, a self-administered online questionnaire from 253 air passengers was obtained, and data was analyzed using SPSS 25 software. The results reveal that performance expectancy, price-value, hedonic motivations, perceived benefits and habit have a positive significant influence on behavioral intention, while social influence, perceived challenges, facilitating conditions and effort expectancy were not supported. The results of the study give insights into how different passengers, different age groups, different geographical locations, and different technological maturity perceive such implementations. This will provide policymakers ideas on how to better manage and enhance e-services.Yayın The impact of market place persona based neuromarketing on brand identity and consumer attitude on SDG's(Editora Alumni In, 2024) Pasaribu, Popy Novita; Kemora, Haura; Eosina, Puspa; Marlina, Asti; Himawan, Erry NugrohoObjective: The objective of this study is to investigate the impact of persona-based neuromarketing on brand identity and consumer attitude in the digital marketplace, with the aim of understanding how neuromarketing principles can enhance consumer engagement and marketing effectiveness.

As a result of the lockdown associated with the pandemic, the economies of the world were affected through restrictions like lockdown leading to the reduction of economic indicators like Gross Domestic Product (GDP) and increase in Unemployment. This paper set out to look at the relationship between the GDP and unemployment in Ghana in the periods prior and during the covid pandemic. The Autoregressive Distributed Lag (ARDL) model was used on data from 1991 to 2021. The result shows the nonexistence of the Okun’s law in Ghana in each of these periods. We conclude by advising policy makers to implement policies that directly generate more jobs like improvement in the agriculture sector through training and financial support to enable increased employment to match the increase in economic growth.Yayın Assessing the impact of seasonal changes on advertising revenues in the age of digitalization and sustainability: A print-visual media business example(Busssecon International Academy, 2024) Camci, Aykut; Aksoy, Tamer; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study mainly aimed to investigate the impact of seasonal changes on media advertising revenues (AR) in R environment through a visual-print media company example. So, the study primarily aimed to examine whether visual, print and internet ARs were affected by seasonal change. The study also aimed to indicate the trends of visual/ print/ and internet ARs over time in the light of seasonality. Furthermore, it was also aimed to make AR estimates for the next year with the best performing methods covering ARIMA and ETS. Methodologically, R programming language and its libraries were used together with ARIMA and ETS time series models. The data set consisted of a monthly ARs series consisting of 180 rows covering the period between January/2007-December/2021 and having a sufficient number of observations for the application of the models. Data were analyzed with R and next year’s forecasts were done with ARIMA and ETS. The study revealed that all AR types were affected by seasonal changes in the specified period and included seasonality, i.e. specially in the summer months. Additionally, it was observed that AR types have different trends despite containing seasonality. The study found that visual ARs denoted a slight downward trend including seasonality during the period. It was also indicated that print ARs reflected a very rapid and drastic downward trend covering seasonality. The study also revealed that internet ARs showed a very rapid and sharp upward trend compared to the other two AR types despite having seasonality. Furthermore, taking into account the calculated error metrics, it was found that the ARIMA model showed the best estimation performance in both i.e. visual and internet ARs. On the other hand, the ETS model indicated the best estimation performance in print ARs. Accordingly, estimations of the visual/print and internet ARs for the next year were made with the best performing methods. It was pointed out that estimated ARs included seasonality in the summer months and revealed similar results to the previous trends based on historical data.Yayın Evaluation of maintenance strategies using Pythagorean fuzzy sets: A novel model for time-constrained processes(Taylor & Francis, 2025) Sancar, Semih; Kuşakcı, Ali Osman; Ayvaz, Berk; Yönetim Bilimleri Fakültesi, İşletme BölümüConsidering the large investment cost as well as expectations such as increased awareness ofoccupational safety and quality, choosing the appropriate maintenance strategy emerges as acritical decision. Time-constrained production processes, which demand defect-free produc-tion within a limited timeframe, intensify the significance of this selection problem. In suchproduction processes, the product is generally short-lived, so stocking is not possible.Therefore, halting operations incurs significant costs. In this study, we aim to choose themost appropriate maintenance planning strategy for time-constrained processes. Given thatthe process of selecting a maintenance strategy is ambiguous and lacks conclusive assess-ments, it involves numerous hazy criteria. Thus, this study presents a framework that includesthe Pythagorean Fuzzy AHP-CRITIC-Entropy combined weighting method hybridized withPythagorean Fuzzy WASPAS. The model evaluates the maintenance options of Türkiye’s largestprinting company, which operates under time-constrained processes, in a real-world case studyproving the merit of the proposed methodology.Yayın Medeniyet ve cemiyet harmanı: İslâm şehirleri (7-19. yüzyıl)(Yasemin Özcan, 2021) Özkan, Merve NurŞehirlerin, yeni medeniyetlere kapı açmasıyla öznel; medeniyet ve cemiyetler tarafından şekillenmesi ile nesnel olmak üzere iki yönü olmuştur.
