Contingency learning of social cues: Neural engagement and emotional modulation by facial expressions
(Frontiers, 2025) Saylık, Rahmi; Uysal, Burcu; Williams, Adrian Loyd; Murphy, Robin A.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Contingency learning—the fundamental process by which associations are formed between events in our experience is as relevant of conditioning as it is for social interactions, where emotional cues, such as facial expressions, signal complex and reciprocal causal dynamics. This study investigates the functional neuroanatomy underlying contingency perception by with three type of contingent relation (positive, zero, and negative) using sad and happy facial expressions as stimuli in a group of neurotypical participants. Employing a streaming trial paradigm and functional MRI, we examined how these emotional contingencies engage brain regions involved in attention and predictive processing. The behavioural results indicated that participants could distinguish between different contingencies, regardless of the emotional stimuli. However, judgment ratings varied across conditions, with sad expressions eliciting weaker ratings compared to happy expressions, which moderated perceived causality, especially in the uncorrelated and negative contingency tasks. These behavioural findings were primarily linked to increased activation in frontal regions, including the inferior frontal gyrus, middle frontal gyrus, and anterior cingulate cortex. The results highlight the differential cognitive demands and neural responses evoked by emotional expressions and suggestive of the idea that statistical relations that violate social expectations are processed differently than positive relations.

(AVES, 2024) Altıntaş, Merih; Başgül, Şaziye Senem; Avcu, Akif; Macit, Ruken; Büyüköztürk, Şener; Dinçer, Duygu; Özdenler, Merve; Öztürk, Ömer Mücahit; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Background: The aim of this quantitative study conducted with 5008 individuals aged 15 and above in 12 provinces across Turkey was to determine the prevalence and significant variables of gambling behavior in our country and to examine the gambling behaviors, perceptions, thoughts, and attitudes of this population towards gambling. The goal is to generate concrete, original, culturally sensitive, feasible, and effective recommendations for preventive and risk-reducing policies. It is the first and only comprehensive investigation into gambling behavior in Turkey, offering guidance in this field. Methods: In this study, which was conducted with an epidemiological cross-sectional design, a stratified random sampling technique was employed, and data were collected using computer-assisted faceto-face interviews. Individuals to be surveyed in households were randomly selected using the Kish method. Results: Three hundred forty-one participants (6.81%) reported having gambled at least once (GALO) in their lifetime, while the remaining participants stated they had never gambled (NG). Among the GALO group, 100 individuals (29.33%) reported regular participation in gambling activities during the data collection period. The most commonly played types of gambling were sports betting (55.4%), national lottery (42.2%), numeric lottery (34.6%), and bingo (30.8%). The ages of first-time gambling ranged from 6 to 41. Tobacco, alcohol, and substance use were significantly more common in the GALO group compared to the NG group (P < .001). Conclusion: Understanding the prevalence of gambling behavior and underlying motivations is crucial for creating awareness and implementing effective preventive measures. We must determine its prevalence, examine societal attitudes, highlight its presence, and prioritize solution-oriented strategies.
The Reicher-Wheeler paradigm in word recognition research: A cautionary note on its actual contributions and published misconceptions
(Frontiers Media SA, 2024) Jordan, Timothy R.; Akkaya, Aziz M.; Göçmüş, Fatma Zehra; Kalan, Aleynanur; Morgül, Ebru; Önalan, Kübra; Sheen, Mercedes Kier; Akkaya, Aziz Muhammed; Morgül, Ebru; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
The study of word recognition has been influenced greatly by findings obtained when visual stimuli are presented very briefly. Under these conditions, a great deal of evidence suggests that words are perceived better than nonwords, and even single letters, and it is generally accepted that these “word superiority effects” reflect the relative efficiency with which words are perceived. For more than 50 years, a key procedure for establishing these effects has been the Reicher-Wheeler Paradigm in which potentially confounding effects of non-perceptual guesswork are cleverly suppressed. More recently, however, the actual nature of the ReicherWheeler paradigm and its contribution to research have become misrepresented in a range of publications, and its use in experiments has been confused and conflated with other, less sophisticated procedures. In this article we describe the actual contributions made by the Reicher-Wheeler Paradigm to word recognition research and show examples of how these important contributions have been misunderstood and misconceived in experiments reported in the recent literature.
A further look at perception of personalities in typefaces: Evidence from Turkish
(SAGE Publications, 2025) Sheen, Mercedes; Yekani, Hajar Aman Key; Morgül, Ebru; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Previous research conducted in English indicates that the visual appearances of different typefaces are perceived as possessing distinct characteristics, what we call “print personality” (e.g., masculine, feminine, serious, fun) to the extent that the typeface used conveys information to the reader beyond that which is expressed linguistically by the word. Recent work has found that these attributions of “print personality” also extend to typefaces written in Arabic, but one language that is distinct from both languages is Turkish. Turkish is written in a version of the Latinate alphabet containing 29 letters which include unique diacritics and is a genderless language which requires no gender associations for nouns, pronouns, or adjectives. Given that many print personalities appear to be strongly associated with gender (masculine, feminine, elegance, confidence), it remains to be determined if the association of print personalities extends to Turkish typefaces, and the pattern of any such associations. Accordingly, sixteen different typefaces were presented to fluent native Turkish readers who rated each typeface according to 22 different personality characteristics. The results indicate that, although Turkish participants readily assigned personality characteristics to different typefaces, gendered associations across different typefaces were far weaker than previously found. Implications for the generality of the existence of typeface personalities across different languages, and the effect this may have on perception of genderless languages, are discussed.
Exploring vaccine hesitancy in digital public discourse: From tribal polarization to socio-economic disparities
(Public Library of Science, 2024) Ayaz, Huzeyfe; Çelik, Muhammed Hasan; Koytak, Hüseyin Zeyd; Yanık, İbrahim Emre; İnsan ve Toplum Bilimleri Fakültesi, Sosyoloji Bölümü
This study analyzed online public discourse on Twitter (later rebranded as X) during the COVID-19 pandemic to understand key factors associated with vaccine hesitancy by employing deep-learning techniques. Text classification analysis reveals a significant association between attitudes toward vaccination and the unique socio-economic characteristics of US states, such as education, race, income or voting behavior. However, our results indicate that attributing vaccine hesitancy solely to a single social factor is not appropriate. Furthermore, the topic modeling of online discourse identifies two distinct sets of justifications for vaccine hesitancy. The first set pertains to political concerns, including constitutional rights and conspiracy theories. The second pertains to medical concerns about vaccine safety and efficacy. However, vaccine-hesitant social media users pragmatically use broad categories of justification for their beliefs. This behavior may suggest that vaccine hesitancy is influenced by political beliefs, unconscious emotions, and gut-level instinct. Our findings have further implications for the critical role of trust in public institutions in shaping attitudes toward vaccination and the need for tailored communication strategies to restore faith in marginalized communities.
A PERMA model approach to well‑being: A psychometric properties study
(Springer Nature, 2024) Al-Hendawi, Maha; Alodat, Ali; Al-Zoubi, Suhail; Bulut, Sefa; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü
Psychological well-being infuences all the facets of adolescent success. This study examined the psychometric prop erties of PERMA, a subjective well-being measure consisting of fve domains: positive emotions, engagement, relation ships, meaning, and accomplishment. The sample size consisted of 502 high school students from public schools in Qatar. Contrary to expectations, the fve-factor structure for PERMA did not ft our data well; however, after refning the model by the errors of the covariances between items, the one-factor model was found to be applicable. Mul tivariate analysis revealed that socioeconomic status (SES) and level of academic performance were independently and positively associated with overall well-being scores, whereas internalizing and externalizing behaviors were negatively associated. Notably, no signifcant efects of gender or age on well-being were observed. These fndings suggest that interventions specifc to socioeconomic status, academic excellence, and internalizing and externalizing behaviors in the school setting can produce more efective outcomes concerning student well-being.
Revealing a word superiority effect using a unique variant of the Latin alphabet: The evidence from Turkish
(Frontiers, 2024) Jordan, Timothy R.; Kalan, Aleynanur; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
When visual stimuli are presented briefly, words are perceived better than nonwords. It is widely accepted that this word superiority effect reflects the efficiency with which words are perceived. However, most of what is known about the effect comes from languages (like English) using the basic Latin alphabet and little is known about whether languages using an alphabetic variant with very different properties can also produce word superiority. Here we report an experiment in which words and nonwords were presented briefly in Turkish, which uses a unique variant of the Latin alphabet containing 29 separate letters, 12 of which are close visual replications of other letters. Despite the potential for visual confusability and perceptual uncertainty, the findings revealed a clear advantage for words over nonwords, indicating that word superiority observed previously for the Latin alphabet can also be observed with the very different variant of this alphabet used for Turkish. Implications of these findings for processes involved in visual word perception are discussed.
Does oral iron and folate supplementation during pregnancy protect against adverse birth outcomes and reduced neonatal and infant mortality in Africa: A protocol for a systematic review and meta-analysis?
(Sage Publications, 2024) Bekele, Yibeltal; Gallagher, Claire; Batra, Mehak; Buultjens, Melissa; Eren, Senem; Erbaş, Bircan; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Background: Globally, one-third of pregnant women are at risk of iron deficiency, particularly in the African region. While recent findings show that iron and folate supplementation can lower the risk of adverse birth outcomes and childhood mortality, our understanding of its impact in Africa remains incomplete due to insufficient evidence. This protocol outlines the systematic review steps to investigate the impact of oral iron and folate supplementation during pregnancy on adverse birth outcomes, neonatal mortality and infant mortality in Africa. Methods and analysis: MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Web of Science, and Cochrane databases were searched for published articles. Google Scholar and Advanced Google Search were used for gray literature and nonindexed articles. Oral iron and/or folate supplementation during pregnancy is the primary exposure. The review will focus on adverse birth outcomes, neonatal mortality and infant mortality. Both Cochrane Effective Practice and Organization of Care and Newcastle-Ottawa Scale risk of bias assessment tools will be used. Meta-analysis will be conducted if design and data analysis methodologies permit. This systematic review and meta-analysis will provide up-to-date evidence about iron and folate supplementation’s role in adverse birth outcomes, neonatal mortality and infant mortality in the African region. Ethics and dissemination: This review will provide insights that help policymakers, program planners, researchers, and public health practitioners interested in working in the region.

Multicenter registry and test bed for extended outpatient hemodynamic monitoring: The hemodynamic frontiers in heart failure (HF2) initiative
(Frontiers, 2023) Heywood, J. Thomas; Munshi, Kartik; Jordan, Timothy R.; Muse, Evan; Fudim, Marat; Sauer, Andrew J.; McDermott, Margaret; Shah, Hirak; Bhimaraj, Arvind; Khedraki, Rola; Robinson, Monique R.; McCann, Patrick; Volz, Elizabeth; Guha, Ashrith; Jonsson, Orvar; Bhatt, Kunjan A.; Bennett, Mosi K.; Benjamin, Terrie Ann; Guglin, Maya; Abraham, Jacob; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Background: Hemodynamic Frontiers in Heart Failure (HF2) is a multicenter academic research consortium comprised of 14 US institutions with mature remote monitoring programs for ambulatory patients with heart failure (HF). The consortium developed a retrospective and prospective registry of patients implanted with a wireless pulmonary artery pressure (PAP) sensor. Goals/aims: HF2 registry collects demographic, clinical, laboratory, echocardiographic (ECHO), and hemodynamic data from patients with PAP sensors. The aims of HF2 are to advance understanding of HF and to accelerate development of novel diagnostic and therapeutic innovations. Methods: HF2 includes adult patients implanted with a PAP sensor as per FDA indications (New York Heart Association (NYHA) Class III HF functional class with a prior hospitalization, or patients with NYHA Class II or brain natriuretic peptide (BNP) elevation without hospitalization) at a HF2 member site between 1/1/19 to present. HF2 registry is maintained at University of Kansas Medical Center (KUMC). The registry was approved by the institutional review board (IRB) at all participating institutions with required data use agreements. Institutions report data into the electronic registry database using REDCap, housed at KUMC. Results: This initial data set includes 254 patients implanted from the start of 2019 until May 2023. At time of device implant, the cohort average age is 73 years old, 59.8% are male, 72% have NYHA Class III HF, 40% have left ventricular ejection fraction (LVEF) < 40%, 35% have LVEF > 50%, mean BNP is 560 pg/ml, mean N-Terminal pro-BNP (NTproBNP) is 5,490 pg/ml, mean creatinine is 1.65 mg/dl. Average baseline hemodynamics at device implant are right atrial pressure (RAP) of 11 mmHg, pulmonary artery systolic pressure (PASP) of 47 mmHg, pulmonary artery diastolic pressure (PADP) 21 mmHg, mean pulmonary artery pressure (mPAP) of 20 mmHg, pulmonary capillary wedge pressure (PCWP) of 19 mmHg, cardiac output (CO) of 5.3 L/min, and cardiac index (CI) of 2.5 L/min/m2. Conclusion: A real-world registry of patients implanted with a PAP sensor enables long-term evaluation of hemodynamic and clinic outcomes in highly-phenotyped ambulatory HF patients, and creates a unique opportunity to validate and test novel diagnostic and therapeutic approaches to HF.
Sleep quality, quality of life, fatigue, and mental health in COVID-19 post-pandemic Türkiye: A cross-sectional study
(Frontiers, 2024) Bener, Abdulbari; Morgül, Ebru; Tokaç, Mahmut; Ventriglio, Antonio; Jordan, Timothy R.; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Aim: This study explores the predictors and associated risk factors of sleep quality, quality of life, fatigue, and mental health among the Turkish population during the COVID-19 post-pandemic period. Materials and methods: A cross-sectional survey using multi-stage, stratified random sampling was employed. In total, 3,200 persons were approached. Of these, 2,624 (82%) completed the questionnaire package consisting of socio-demographic information, Pittsburgh Sleep Quality Index (PSQI), the WHO Quality of Life Brief Version (WHOQOL-BREF), Fatigue Assessment Scale (FAS), Patients Health Questionnaire (PHQ-15), GAD-7 anxiety scale, and the 21-item Depression, Anxiety, Stress Scale (DASS-21). Results: Significant differences between genders were found regarding socio-demographic characteristics (p < 0.01). Using PHQ-15 for depressive disorders, significant differences were found between normal and high severity scores (≥ 10), regarding age group (p < 0.001), gender (p = 0.049), educational level (p < 0.001), occupational status (p = 0.019), cigarette smoking (p = 0.002), waterpipe-narghile smoking (p = 0.039), and co-morbidity (p = 0.003). The WHOQOL-BREF indicated strong correlations between public health, physical health, psychological status, social relationships, environmental conditions, and sleep disorders (p < 0.01). Furthermore, comparisons of the prevalence of mental health symptoms and sleeping with PHQ-15 scores ≥ 10 (p = 0.039), fatigue (p = 0.012), depression (p = 0.009), anxiety (p = 0.032), stress (p = 0.045), and GAD-7 (p < 0.001), were significantly higher among the mental health condition according to sleeping disorder status. Multiple regression analysis revealed that DASS21 stress (p < 0.001), DASS21 depression (p < 0.001), DASS21 anxiety (p = 0.002), physical health (WHOQOL-BREF) (p = 0.007), patient health depression-PHQ-15 (p = 0.011), psychological health (WHOQOL-BREF) (p = 0.012), fatigue (p = 0.017), and environmental factors (WHOQOL-BREF) (p = 0.041) were the main predictor risk factors associated with sleep when adjusted for gender and age. Conclusion: The current study has shown that sleep quality was associated with the mental health symptoms of depression, anxiety, stress, and fatigue. In addition, insufficient sleep duration and unsatisfactory sleep quality seemed to affect physical and mental health functioning.
A scoping review of studies on assistive technology interventions and their impact on individuals with autism spectrum disorder in Arab countries
(MDPI, 2023) Bulut, Sefa; al-Hendawi, Maha; Hussein, Esraa; Al Ghafri, Badriya; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü
The rising prevalence of autism spectrum disorder (ASD) in Arab countries necessitates evidence-based interventions. Assistive technology (AT) presents a promising approach. However, data on the pervasiveness of AT use and its effectiveness for individuals with ASD, specifically within Arab countries, remain scarce. Objective: To review the current literature on the AT interventions and outcomes reported for individuals with ASD in Arab countries. Methods: A scoping review adhering to PRISMA guidelines was undertaken to explore the utilization of AT, segmented into three categories: low-technology (low-tech), mid-technology (mid-tech), and high-technology (high-tech) devices. Results: Twelve studies had a pooled sample of 1547 participants, primarily male school-aged children with ASD. The AT applications evaluated ranged from low-tech visual schedules and support to high-tech virtual reality systems. Studies have reported the potential benefits of AT in improving communication, social, academic, adaptive, and functional abilities; however, comparative evidence between AT interventions is limited. The identified barriers to the adoption of AT included caregiver uncertainty about the use of AT and a lack of awareness of AT among professionals and the Arab community in general. Conclusion: Available studies suggest that the adoption of AT can enhance the skills of individuals with ASD in Arab countries. However, more rigorous studies across diverse demographic groups and Arab national regions are needed to strengthen the evidence base and provide appropriate recommendations.
Is the effect of a health crisis symmetric for physical and digital financial assets? An assessment of gold and bitcoin during the pandemic
(Public Library of Science, 2023) Badshah, Waqar; Musah, Mohammed; Khan, Asad ul Islam; Özer, Ercan; Yönetim Bilimleri Fakültesi, İktisat Bölümü
The emergence of the covid-19 health crisis, in this advanced technological era where connections between markets, nations, and economies have grown stronger than ever before, the shock of the COVID-19 pandemic quickly had an impact on both physical and digital financial assets. The Chinese financial market experienced the first consequences of the covid-19 pandemic, then spilled over to other financial markets, including those for cryptocurrencies and the precious metals. This study examines the impact of the covid-19 pandemic on the volatilities of the dynamics of bitcoin and gold. Both assets share some characteristics, such as online trading platforms, however, gold is a tangible financial asset unlike bitcoin, which is digitally generated without any physical form. This study argues that the similarities and differences between bitcoin and gold play major roles in how the covid19 crisis affected their respective dynamics. Using daily data ranging from 9/22/2014 to 1/ 31/2023 and employing ARMA as the mean equation for GARCH model, the impact of the health crisis (covid-19) is examined on the volatilities of the prices and volumes of bitcoin and gold. Empirical evidence points out that, the pandemic has a symmetric impact on the volatilities of bitcoin and gold price returns, causing them to be more volatile. The impact of the covid-19 observed on the volume returns of the assets, however, is asymmetrical. The empirical results give evidence to the role that the vital differences existing between these assets played during the covid-19 pandemic.
Strengths and weaknesses of inviting men to a voluntary-based domestic violence intervention
(SAGE Publications, 2023) Turhan, Zeynep; Fırat, Engin; Genç, Emel; Başer Baykal, Nur; Ulus, İhsan Çağatay; Bulut, Sefa; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü
This study examines the factors motivating domestic violence perpetrators to participate in a voluntary-based intervention program. The experiences and determining factors around men’s positive and negative responses to this invitation were examined through semi-structured interviews with professionals, observations, and reflexive notes during the first meeting with 29 men. Two major themes emerged from the thematic analysis: the factors making men more likely to attend the first meeting or resisting the group intervention. These findings can help professionals recognize the challenges of inviting perpetrators to interventions, especially in countries with insufficient laws for mandated domestic violence perpetrator programs. The paper discusses the importance during the first meeting of building rapport and trust and recognizing complex family histories to encourage voluntary attendance and intervention engagement.
Adjustment challenges and coping strategies of Arab female international university students
(Frontiers, 2023) Nazir, Thseen; Özçiçek, Ayşe; Lilla, Nanine; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü
Over the past decade, Türkiye has experienced an increasing influx of international students, particularly from various Arab countries. The significant number of Arab international university students has prompted researchers to pay more attention to the experiences of this population in the country. This study examined the adjustment problems experienced by Arab female international university students in Türkiye…
Reducing test anxiety during the COVID-19 pandemic: A comparison of the effectiveness of cognitive behavioral therapy and acceptance and commitment therapy
(Sage Journals, 2023) Jordan, Timothy R.; Uysal, Burcu; Görmez, Vahdet; Karatepe, Hasan Turan; Sönmez, Dilruba; Taştekne, Feyzanur; Tepedelen, Mehmed Seyda; İnsan ve Toplum Bilimleri Fakültesi, Psikoloji Bölümü
Educational assessments can affect students' mental health, particularly during a pandemic. Acceptance and Commitment Therapy (ACT) and Cognitive Behavioral Therapy (CBT) are widely efficacious for reducing test anxiety, as well as general anxiety and rumination. However, the effectiveness of these two therapies for students during COVID-19 is unclear. We measured the effectiveness of ACT and CBT for managing test anxiety, general anxiety, and rumination during COVID-19 for 77 students taking Türkiye's national university entrance exam, assigned to either the ACT or CBT psychoeducation programs. Both programs reduced test anxiety, general anxiety, and rumination, and showed similar levels of effectiveness. This suggests that ACT and CBT are both important for improving students' mental health during COVID-19 and either may be beneficial.
Till debt does us apart: Cross-country evidence on the relationship between microfinance prevalence and social distrust
(Public Library Science, 2023) Khan, Asad ul Islam; Özcan, Rasim; Masood, Syed Muhammad Usman; Yönetim Bilimleri Fakültesi, İktisat Bölümü
Economic interventions have social consequences. In this paper, we explore one such relationship, between microfinance intensity and social distrust levels reported by the low-income people. We find a significant association between microfinance intensity in a country and distrust among the poor as well as ultra-poor in cross-section using World Values Survey & European Values Survey (WVS-EVS) Wave 7 (2017-2022). We supplement these findings using empirical Bayes on a panel extending back from 7th to the 4th WVS wave (1999-2004). To deal with potential endogeneity, we run 2SLS as well as weak instruments-robust conditional instrumental variable tests and find evidence showing microfinance prevalence intensity affects distrust levels among the poor and ultra-poor households. We find no association between microfinance and distrust levels in the rich in any of the tests, potentially because the rich are not exposed to microfinance.
Commitment profiles for employee voice: Dual target and dominant commitment mindsets
(SpringerLink, 2023) Çalışkan, Sibel; Ünler, Ela; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Based on the person-centered approach and the EVLN (exit, voice, loyalty, neglect) model, this study explores how the components of commitment create “profles” and the implications of this for voice behaviors in response to malpractice at work. The study includes not just afective and continuance commitment forms but also a commitment to the team as a multi-target commitment. A survey was conducted of 518 employees from a broad range of organizations in Turkey. An attempt was made to diferentiate the EVLN responses across diverse commitment profles by expanding the context. Four clusters (low commitment, weakly-committed, afective–team dominant, and continuance dominant) were identifed using k-means cluster analysis. Analysis of the variance results indicated that the afective–team dominant profle demonstrated the constructive voice. The low commitment profle showed the least desirable outcomes (exit and neglect), followed by the weakly-committed profle. The continuance dominant profle also demonstrated passive behaviors (neglect and patience). Afective and team commitments, which have similar foci, were found to be the primary drivers of voice behavior, especially when combined with low continuance commitment. Also, continuance commitment did not contribute to the voice behavior once a certain level of afective and team commitment was seen. This study contributes to expanding commitment profles for data from Turkey by explaining diverse EVLN responses to dissatisfaction at work.
The power of e-recruitment and employer branding on Indonesian millennials’ intention to apply for a job
(Frontiers Media S.A., 2023) Wijaya, Cindy Natalia; Mustika, Martina Dwi; Bulut, Sefa; Bukhori, Baidi; Eğitim Bilimleri Fakültesi, Rehberlik ve Psikolojik Danışmanlık Bölümü
Companies need reliable employees to support their business. As e-grocery businesses in Indonesia continue to grow during the pandemic, various strategies are required to attract millennials. This study aims to prove the influence of employer branding, e-recruitment, and post-pandemic employee value proposition (radical flexibility, deeper connection, personal growth, and holistic well-being) in encouraging millennials to apply for jobs at e-grocery companies after the pandemic. Few e-grocery companies in Indonesia use employer branding and e-recruitment; this study attempts to combine these two variables to see the effect of their interaction on influencing greater millennial intentions. Using the latest experimental method, which is the experimental vignette method, we conducted three studies with a total of 619 millennial participants, who were recruited using the convenience sampling technique. All participants received a set of job advertisements as a stimulus. The results showed that e-recruitment could not significantly predict the millennials’ intentions when applying for jobs in e-grocery companies. Companies in Indonesia may need to analyze millennials’ familiarity with e-recruitment platforms, especially on company websites. However, employer branding successfully predicted millennials’ intention to apply for a job in e-grocery companies, which was not affected by the length of their work experience. Employer branding serves as a means of building job seekers’ trust through personal promotions. With this trust, job seekers are more motivated to apply to the company. When e-recruitment and employer branding were analyzed simultaneously, there were significant interactive effects on millennials’ intentions. Employer branding acted as a socialization medium to introduce e-recruitment and vice versa. E-recruitment served as a form of branding that could shape the perceptions and experiences of millennial job seekers. Lastly, the employee value proposition significantly predicted millennials’ intentions, where holistic well-being was the most sought-after value. It can support employees’ well-being and encourage them to make valuable propositions that will make e-grocery companies excel in Indonesian labor market.
Does environmental sustainability afect the renewable energy consumption? Nexus among trade openness, CO2 emissions, income inequality, renewable energy, and economic growth in OECD countries
(Springer Nature, 2022) Özcan, Rasim; Muhammad, Iftikhar; Jain, Vipin; Sharma, Paritosh; Shahzad Shabbir, Malik; Yönetim Bilimleri Fakültesi, İktisat Bölümü
This study investigates the impact of carbon emissions, real oil prices, income inequality, economic growth, and trade openness on renewable energy consumption (REC) in twenty-three (23) OECD economies. The study employs the Westerlund panel cointegration technique to verify the existence of long-run equilibrium and the Augmented Mean Group (AMG) estimator to assess the long-run relationship between the variables, which allows for slope heterogeneity and cross-sectional dependency. Moreover, the panel causality test of Dumitrescu and Hurlin (DH) is utilized to gauge the causal relationship between the variables. The fndings of our study reveal that REC is positively related to economic growth, real oil prices, income inequality, and trade openness, but negatively related to CO2 emissions in OECD countries. In addition, there is one-way causality from GDP per capita to renewable energy consumption and a bidirectional causality between income inequality and REC. Furthermore, the results indicate that OECD policymakers and governments should regard foreign trade as a “clean energy fostering mechanism” while developing energy demand policies that are environmentally friendly.
A critical analysis of COVID-19 research literature: Text mining approach
(Elsevier, 2021) Delen, Dursun; Delen, Dursun; Delen, Dursun; Zengul, Ferhat D.; Zengul, Ayşe G.; Mugavero, Michael J.; Oner, Nurettin; Özaydın, Bünyamin; Delen, Dursun; Willig, James H.; Kennedy, Kierstin C.; Cimino, James; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Objective: Among the stakeholders of COVID-19 research, clinicians particularly experience difficulty keeping up with the deluge of SARS-CoV-2 literature while performing their much needed clinical duties. By revealing major topics, this study proposes a text-mining approach as an alternative to navigating large volumes of COVID-19 literature. Materials and methods: We obtained 85,268 references from the NIH COVID-19 Portfolio as of November 21. After the exclusion based on inadequate abstracts, 65,262 articles remained in the final corpus. We utilized natural language processing to curate and generate the term list. We applied topic modeling analyses and multiple correspondence analyses to reveal the major topics and the associations among topics, journal countries, and publication sources. Results: In our text mining analyses of NIH’s COVID-19 Portfolio, we discovered two sets of eleven major research topics by analyzing abstracts and titles of the articles separately. The eleven major areas of COVID-19 research based on abstracts included the following topics: 1) Public Health, 2) Patient Care & Outcomes, 3) Epidemiologic Modeling, 4) Diagnosis and Complications, 5) Mechanism of Disease, 6) Health System Response, 7) Pandemic Control, 8) Protection/Prevention, 9) Mental/Behavioral Health, 10) Detection/Testing, 11) Treatment Options. Further analyses revealed that five (2,3,4,5, and 9) of the eleven abstract-based topics showed a significant correlation (ranked from moderate to weak) with title-based topics. Conclusion: By offering up the more dynamic, scalable, and responsive categorization of published literature, our study provides valuable insights to the stakeholders of COVID-19 research, particularly clinicians.
