A trait activation theory lens on hospitality employees' ethicality at work: unveiling the dark side of error tolerance
No full textWhile literature on ethicality among hospitality employees is emerging, understanding the context within which individuals choose to behave ethically or unethically is still in its infancy. Taking a holistic "person-environment" view, this paper draws upon the trait activation theory (TAT) to examine the impact of Machiavellianism as an individual disposition on employees' moral disengagement as well as ethicality-related behaviors, contingent on perceived error tolerance at work. The results from multi-wave and multi-source data collected among employees in fine dining rooms reveal that employees high on Machiavellianism are more likely to be morally disengaged when they perceive a higher level of error tolerance. Furthermore, this moral disengagement subsequently results in creative unethical behavior but lessens rule compliance. Implications for business practices are provided, along with suggested directions for future research.National Natural Science Foundation of China (NSFC) ; Hong Kong Polytechnic Universit
A Jungian psychosocial approach to entrepreneurship: The case of woman entrepreneurs in Turkey
No full textPurpose - The relationship between feminine and masculine qualities is usually seen as a hierarchy and dichotomy, and what affects people's choices of these qualities remain largely unanswered. Through this study, we aim to elucidate variations in women entrepreneurs' entrepreneurial behaviour and definitions of success by using the Jungian psychosocial framework. Design/methodology/approach - Through 28 semi-structured in-depth interviews, we investigated female entrepreneurs' entrepreneurial behaviour in Turkey's unique, non-western, developing-economy context, surrounded by mixed cultural values melding East and West. Findings - In brief, we found that women entrepreneurs, being greatly affected by their psychosocial contexts, use different archetypal masculine and feminine qualities with various degrees during their entrepreneurial journeys. Thus, entrepreneurial behaviour results from deliberate choices of archetypal masculine and feminine qualities existing on a continuum and shaped by the specific psychosocial context of the individual entrepreneur. Moreover, the choices of different archetypal qualities play a significant motivational role in the construction of entrepreneurs' definitions of success, which seems to align with the individuation phenomenon Jung described as the life purpose of every individual. Originality/value - The Jungian framework we introduce to the field offers an alternative, yet comprehensive and enriching solution, to the problematic dichotomy of the qualities underlying entrepreneurship behaviour and offers a solid theoretical base in expanding the definition of success
AI-assisted architectural design studio (AI-a-ADS): How artificial intelligence join the architectural design studio?
No full textIncorporating AI into design is a current and promising research topic. This article investigates and discusses the integration of AI tools into architectural design studios. A 4-stage research methodology (DCIE) is adopted in the article. Accordingly, in the first stage (discovery), the relationship between architectural design education and technology is examined. The second stage (creating) involves planning the architectural design studio (AI-a-ADS) and the workshop with an original setup by instrumentalising AI. In this workshop, AI (Midjourney) is used to relate different materials (text, perspective, and model) in the design process in a heterogeneous dialogue. The third phase (implementation) is the implementation of the workshop. In the final phase (evaluation), the workshop was evaluated by its participants within the framework of AI-a-ADS. The research findings indicate that AI integration supports students in developing their projects and forming the basis for some spatial solutions. Additionally, key issues emerged regarding AI applications in architectural design studios. It is crucial to produce materials that provide design context clues, define AI requirements in advance, and convey technical knowledge in such cases. At the same time, the research has demonstrated the significance of generating uncertain outputs for artificial intelligence to become co-designers. Thus, strategies can be prepared to trigger innovative ideas, and discussing vague outputs in a polyphonic studio environment can trigger the emergence of new potentials.TÜBİTAKPublisher versio
The use of islamic geometric patterns for structural design: Structural performance of reciprocal frame structure based on 24-pointed star polygon
No full textIslamic geometric patterns, traditionally used as ornamental elements in Eastern architecture, possess inherent structural logic that resembles reciprocal frame (RF) structures. This study investigates the potential of these patterns to function as structural systems by modeling a 24-pointed star as an RF structure. Structural performance simulations were conducted by varying parameters such as material type (timber and steel), number of supports, material thickness, and span length. Both planar and dome-like geometries were analyzed. The results indicate that increasing material thickness reduces maximum displacement, while smaller spans further enhance structural stability. Steel exhibits lower displacement values compared to timber, whereas timber results in lower moment and shear forces. The findings from the models tested using Karamba3D suggest that tessellated Islamic geometric patterns can serve as alternative structural systems for spanning various distances with short structural elements
Elektrikli araç şarj ünitelerinde güvenli veri i̇letişimi: Görünür ışık haberleşmesi protokolü
No full textNowadays, the Combined Charging System extensively utilized in electric vehicle charging infrastructure transmits data between the car and the charging station via the power line. However, the communication mechanism facilitated by power lines introduces risks to security due to cross-talk among the lines. This study proposes an alternate data transfer protocol that addresses the identified security and application problems. The proposed approach utilizes a communication method called Visible Light Communication, which mitigates interference, reduces line crosstalk, and improves security. This study, in contrast to previous studies in the literature, investigates the technological requirements for implementing VLC-based data transfer as opposed to conventional power line communication in CCS systems, analyzes potential application scenario, and aims for guidance on future research work
Traitors, terrorists, & çapulcus: Protests and the limits of democratic politics in Turkey’s first century and beyond
No full textDespite their crucial role in the country’s political history, protests have not been normalised as a form of participation in Turkey. Neither state authorities nor much of the public consider or treat protests as legitimate and acceptable means of political expression or claims-making. This chapter examines the factors and historical circumstances contributing to this non-normalisation by presenting a brief (and thus unavoidably incomplete) account of the long and complex history of protests in Turkey. It treats this non-normalisation as a facet of one of the republic’s unresolved problems: its failure to constitute a form of democratic, civic citizenship. The chapter argues that protests are not seen as legitimate means of participation in contemporary Turkey due not only to their conflictual and violent history in the twentieth century but also to the boundaries of desirable behaviour for citizens—that is, to how an acceptable citizen is imagined. Within this history, this chapter highlights the Gezi protests of 2013 as a critical moment that revealed the possibility of democratic politics challenging dominant notions of citizenship and participation in Turkey. The chapter concludes with a brief assessment of the discourse on protests under the AKP regime’s populist authoritarian rule, which builds on historical legacies associating protests with illegality and anarchy.Publisher versio
A first process-oriented characterization of eriolobus trilobatus (Labill. ex Poiret) bark from Turkey: Chemical, morphological and energy properties
No full textFor the first time, Eriolobus trilobatus bark from Turkey has been characterized in terms of its chemical, extractive, fuel, and ash characteristics using SEM–EDS, wet chemical analysis, phenolic analysis, FT-IR, TGA, XRF, XRD, BET surface area measurement, proximate analysis, and ash fusion temperature (AFT) determination. The results showed that the bark contains 13% ash, dominated by calcium oxalate, and 15% extractives, largely composed of polar phenolic compounds with moderate radical-scavenging potential. Thermal decomposition of bark proceeds in four distinct stages, associated with the sequential degradation of extractives/hemicelluloses, cellulose, lignin/suberin, and inorganic fractions. The higher calorific value of 14.9 MJ/kg indicates moderate fuel quality compared with conventional woody biomass. Ash is mesoporous with a CaO-rich structure highly suitable for catalytic applications in biodiesel production and biomass gasification. Ash fusion analysis revealed a high flow temperature (1452 °C), indicating a very low slagging risk during thermochemical conversion. Overall, E. trilobatus bark is a promising material for value-added biorefinery pathways, enabling processes for the production of biochars, CaO-based catalysts, phenolic extracts, and sustainable energy. The valorization of E. trilobatus bark not only enhances the economic potential of forestry residues but also provides environmental co-benefits through carbon soil amendment and landscape applications.Publisher versio
Infants’ background television exposure and maternal language input: A home observation study
No full textParental reports and experimental studies indicate that parents speak less to their children in the presence of background television. However, there is a lack of home observations examining the relations between infants’ background TV exposure and maternal infant-directed speech. In the current study, 32 infants and their mothers were observed for 60 minutes in their homes at 8, 10, and 18 months of age. Results revealed that the number of words, the number of different words, and the number of questions in infant-directed speech were consistently lower in households with background TV. Furthermore, these aspects of maternal language input were negatively related to the duration of background TV, controlling for families’ socioeconomic background. These findings suggest that television may have a negative impact on young children’s language development via disrupted parent–child interactions in the presence of background TV in the home environment.Ebeveynlerden alınan bildirimler ve deneysel çalışmalar, arka planda televizyon açıkken ebeveynlerin çocuklarıyla daha az konuştuklarını göstermektedir. Ancak, arka plan televizyon ile ebeveynlerin bebeklerine yönelttikleri dil arasındaki ilişkiyi inceleyen ev gözlemlerine ihtiyaç duyulmaktadır. Bu çalışmada, 32 bebek ve anneleri, bebekler 8, 10 ve 18 aylıkken evlerinde her ziyarette 60’ar dakika boyunca gözlemlenmiştir. Bulgular, arka planda televizyonun açık olduğu evlerde bebeklere yöneltilen dildeki toplam kelime sayısının, farklı kelime sayısının ve soru sayısının tutarlı biçimde daha düşük olduğunu göstermiştir. Ayrıca, bu dil girdisi ölçütleri, ailelerin sosyoekonomik düzeyi kontrol edildiğinde, arka plan televizyon süresiyle olumsuz yönde ilişkili bulunmuştur. Bu bulgular, televizyonun aktif olarak izlenmiyor olsa bile ebeveyn-çocuk etkileşimini sınırlayarak küçük çocukların dil gelişimini olumsuz yönde etkileyebileceğini düşündürmektedir
Ethical and moral pitfalls of generative AI in academic research
No full textDespite the benefits of generative artificial intelligence (GenAI), the use of GenAI in academic research raises moral and ethical concerns. This chapter delves into the adverse impacts of GenAI with a focus on literature review and data collection and analysis. We discuss the issues of research accountability, transparency, and erosion of critical thinking. Since AI systems produce insights from unknown sources, it is difficult to determine who is responsible for biases that may occur. This may lead to a lack of accountability and a potential dilution of researchers’ responsibility. Using GenAI may lead to untrustworthy findings and privacy concerns. Since AI models often operate as “black boxes”, it will be challenging to understand why certain information has been prioritised. Finally, we raise concerns that passively accepting the ease of new content or data analysis processes might potentially limit the production of innovative research, which relies on critical thinking
In-depth analysis of Arabic-origin words in the Turkish morpholex
No full textMorphoLex is an investigation that focuses on analyzing the roots, prefixes, and suffixes of words. Turkish Morpholex, for example, analyzes 48,472 Turkish words. Unfortunately, it lacks in-depth analysis of the Arabic-origin words, and does not include their accurate and correct roots. This study analyzes Arabic-origin words in the Turkish Morpholex, annotating their roots, morphological patterns, and semantic categories. The methodology developed for this work is adaptable to other languages influenced by Arabic, such as Urdu and Persian, offering broader implications for studying loanword integration across linguistic contexts.Publisher versio
