Abortion Services at Hospitals in Istanbul
(Taylor & Francis Ltd, 2017) O'Neil, Mary Lou; Political Science and International Relations; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
Objective: Despite the existence of a liberal law on abortion in Turkey there is growing evidence that actually securing an abortion in Istanbul may prove difficult. This study aimed to determine whether or not state hospitals and private hospitals that accept state health insurance in Istanbul are providing abortion services and for what indications. Method: Between October and December 2015 a mystery patient telephone survey of 154 hospitals 43 public and 111 private in Istanbul was conducted. Results: 14% of the state hospitals in Istanbul perform abortions without restriction as to reason provided in the current law while 60% provide the service if there is a medical necessity. A quarter of state hospitals in Istanbul do not provide abortion services at all. 48.6% of private hospitals that accept the state health insurance also provide for abortion without restriction while 10% do not provide abortion services under any circumstances. Key conclusions: State and private hospitals in Istanbul are not providing abortion services to the full extent allowed under the law. The low numbers of state hospitals offering abortions without restriction indicates a de facto privatization of the service. This same trend is also visible in many private hospitals partnering with the state that do not provide abortion care. While many women may choose a private provider the lack of provision of abortion care at state hospitals and those private hospitals working with the state leaves women little option but to purchase these services from private providers at some times subtantial costs.

Adverse selection in cryptocurrency markets
(Wiley, 2023) Tinic, Murat; Sensoy, Ahmet; Akyildirim, Erdinc; Corbet, Shaen; International Trade and Finance; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
In this article we investigate the influence that information asymmetry may have on future volatility, liquidity, market toxicity, and returns within cryptocurrency markets. We use the adverse-selection component of the effective spread as a proxy for overall information asymmetry. Using order and trade data from the Bitfinex exchange, we first document statistically significant adverse-selection costs for major cryptocurrencies. Also, our results suggest that adverse-selection costs, on average, correspond to 10% of the estimated effective spread, indicating an economically significant impact of adverse-selection risk on transaction costs in cryptocurrency markets. Finally, we document that adverse-selection costs are important predictors of intraday volatility, liquidity, market toxicity, and returns.

Aesthetic Approach for Critical Sociology of Contemporary Communication Technology
(Sage Publications inc, 2024) Arda, Balca; Visual Communication Design; 04. Faculty of Communication; 01. Kadir Has University
Critical theory has already marked that technology often threatens civil liberties, personal autonomy, and rights. Heidegger, later Marcuse, emphasized how technology is not value-free in its own revealing power of the surrounding environment, external and inner nature. Throughout this paper, I explore how the aesthetic approach engages with critical theory and contributes to the sociology of media and communication. For this, I will theoretically survey the terms of sociality under the forces of immediate communication, ubiquitous surveillance, and the compression of time and space that Baudrillard and Virilio once problematized through the lens of critical technology theory to adapt it to media and communication studies. I contend that techno-aesthetics that converge with Ranciere's dissensus can provide practical suggestions on an updated vocation of critical sociology. This article discusses the potential of aesthetic and social criticism of media for democratizing technology that Feenberg inserted. It is urgent to acknowledge the changing spatio-temporal aesthetic regimes that affect the societal imagination and limits of sociality and action to determine the next steps for achieving a commons-based society.

Alone but Together Autonomous but Related: Self-Construal Effects on Happiness in Social Experiences
(Wiley, 2018) Merdin-Uygur, Ezgi; Hesapci, Ozlem; 01. Kadir Has University
Communal tables and open workspaces have become popular servicescapes that is contemporary spaces for experiencing dining or working alone but together. Previous research demonstrates that experiencing with close others (e.g. with friends or family) increases happiness and satisfaction but experiences shared with strangers in contexts such as communal tables or workshops have not yet been thoroughly analyzed. Addressing this research gap from a social-psychological perspective we suggest that even though individuals are generally happier when they share experiences with loved ones self-construal plays a moderating role in the relationship. Individuals with high autonomy and high relatedness do not anticipate greater happiness from experiences shared with friends than with those shared with strangers. Three experimental studies (two online and one field) demonstrate this effect using different operationalizations of autonomy relatedness. Managerial implications are discussed and suggestions are made for future research.

Analysis of efficiency and performance of global retail supply chains using integrated fuzzy SWARA and fuzzy EATWOS methods
(Springer, 2022) Gorcun, Omer Faruk; Zolfani, Sarfaraz Hashemkhani; Canakcioglu, Mustafa; Business Administration; 01. Kadir Has University
The current paper aims to fill the two severe and significant gaps in the literature related to global retail chains. First, it presents the criteria set identified by performing comprehensive fieldwork together with experts highly experienced and have extensive knowledge of the retailing industry and a detailed literature review. Secondly, it proposes a robust, applicable, and powerful novel integrated MCDM framework dealing with many complicated uncertainties. As one of the significant practical and managerial implications, the current paper highlights the significance of sustainable retailing operations to better global retail chains. After the proposed model was implemented, a comprehensive sensitivity analysis was performed to test the validation of the model and its obtained results. According to the validation test results, A12 Walmart&ASDA has remained the best option for all scenarios. It has been observed that there are slight changes that did not change the overall results in the ranking performance of some decision alternatives. As a result, the analysis results prove that the proposed integrated fuzzy approach can be applied to solve highly complex decision-making problems encountered in various fields and the retailing industry.

Antihepatitis B Response To Hepatitis B Vaccine Administered Simultaneously With Tetanus Toxoid in Nonresponder Individuals
(Elsevier Science, 2002) Sönmez, Emine; Sönmez, Ali Suha; Bayındır, Yaşar; Coşkun, Diler; Ariturk, Sedat; 01. Kadir Has University
In this prospective study our aim was to test the effect of simultaneous administration of preS2 and S containing recombinant hepatitis B vaccine (S2SRHB) with tetanus toxoid (TT) to the individuals who did not respond after three doses of hepatitis B vaccine previously. There were three groups (healthy individuals pregnant women hemodialysis patients) each was divided into two subgroups as groups A and B. Group A received S2SRHB + TT and group B received only S2SRHB. We found that in groups receiving both vaccines both seroconversion rate and antibody titer level were significantly higher (P < 0.05). In conclusion simultaneous administration of S2SRHB + TT is more effective than administration of S2SRHB alone. (C) 2002 Elsevier Science Ltd. All rights reserved.

Apolipoprotein B Gene Variants Are Involved in the Determination of Blood Glucose and Lipid Levels in Patients With Non-Insulin Dependent Diabetes Mellitus
(Wiley, 2006) Duman, Belgin Süsleyici; Öztürk, Melek; Yilmazer, Selma; Çağatay, Penbe; Hatemi, Hüsrev; 01. Kadir Has University
We have examined the frequency of the EcoRI XbaI and MspI RFLPs of the apolipoprotein B (apo 13) gene in I 10 type 2 diabetic patients and 9 1 healthy control subjects in order to ascertain whether variation in this gene may influence the development of non-insulin dependent diabetes mellitus (type 2 diabetes). Serum lipids including total-cholesterol (T-Chol) triacylglycerol (TAG) apolipoprotein E (apo E) apolipoprotein Al (apo Al) apolipoprotein B and lipoprotein (a) (Lp(a)) were analysed. Genomic DNA was extracted and the apo B polymorphic regions amplified by the polymerase chain reaction. Regions carrying EcoRI XbaI and MspI restriction sites present in the apo B gene were amplified and digested separately by the respective enzymes. No significant difference for genotypic frequencies was observed for the EcoRI XbaI and MspI restriction sites in type 2 diabetic patients as compared to controls. Type 2 diabetic patients and controls with EcoRI +/+ and XbaI +/+ genotypes had higher apo E levels. The MspI +/+ genotype is more frequent in the patient and control groups With elevated T-Chol. Furthermore the EcoRI -/- XbaI -/- and MspI +/+ genotypes were found to be significantly more frequent in type 2 diabetic patients with higher blood glucose levels. This study identifies the apo B gene polymorphisms in modulating plasma lipid/lipoprotein and glucose levels in patients with type 2 diabetes. Copyright 0 2005 John Wiley & Sons Ltd.

The Associations Between Deviation From the Balanced Time Perspective and Depression and Anxiety: The Moderator Role of Mindfulness in a Two-Wave Study
(Sage Publications inc, 2025) Altan-Atalay, Ayse; Ranjbar, Hamed Abdollahpour; Altintas, Seda; 01. Kadir Has University; Psychology; 03. Faculty of Economics, Administrative and Social Sciences
Deviation from the balanced time perspective (DBTP) refers to difficulties in switching between different time frames in a flexible way by considering the situational demands. DBTP is associated with higher levels of depression and anxiety. Mindfulness acts as a protective mechanism against depression and anxiety. The current study examined the moderator role of mindfulness in the relationship between DBTP and psychological distress. The participants were 243 university students (53.09% women) between ages 18 and 29 (M = 19.88, SD = 1.42) who answered self-report measures of time perspective, mindfulness, anxiety, and depression at two-time points with a five-week time interval. The results showed that the interaction between DBTP and mindfulness measured at time one could prospectively predict both anxiety and depression measured at time two. Mindfulness plays a significant moderating role in the relationship between DBTP and anxiety and depression. The data indicate that for individuals with low levels of DBTP, those with higher mindfulness experience significantly lower anxiety and depression compared to those with lower mindfulness. However, as DBTP increases, anxiety and depression levels in the high mindfulness group rise significantly, ultimately converging with those observed in the low mindfulness group. This indicates that while high mindfulness offers buffering effects against anxiety and depression, these effects diminish under increased DBTP.
Attentional Modulation of Outlier Processing
(Springer, 2025) Gokce, Ahu; Yildirim, Bugay; Boduroglu, Aysecan; Psychology; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
Ensemble perception enables the visual system to function effectively when the number of stimuli in the environment exceeds its capacity. Ensemble representations not only help the limited capacity of visual representations, but they also facilitate the detection and representation of items deviating from the group (i.e., the outlier). This study focuses on how attentional mechanisms modulate outlier processing. In three experiments, we presented participants with an ensemble that was formed by circle stimuli in varying sizes, and the outlier item was distinct in terms of its location. We measured outlier localization performance while manipulating attentional orienting via a spatial cueing paradigm. In Experiment 1, a valid, invalid, or neutral cue was presented before or after the display. Facilitation of outlier localization was most pronounced in the valid precue condition. Experiment 2 included a task to actively engage ensemble perception in addition to outlier localization, and cue validity effect was observed as in Experiment 1. Experiment 3A was carried to directly compare the top-down and bottom-up influences on outlier processing by presenting two spatial outliers-one target and another distractor outlier. The target outlier identity was previously determined and was identical across trials. In Experiment 3B, the target was in red, making it salient among the remaining items. In the invalid trials, where the distractor outlier was cued, responses were closer to the distractor item indicating that outlier processing is cue driven. These experiments overall demonstrate that automaticity of outlier processing can be overridden by cue-driven processes.

Background Tv and Infant-Family Interactions: Insights From Home Observations
(Wiley, 2024) Uzundag, Berna A.; Koskulu-Sancar, Suemeyye; Kuntay, Aylin C.; Psychology; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
Background television has been found to negatively impact children's language development and self-regulatory skills, possibly due to decreased parent-child interactions. Most of the research on the relationship between background TV and caregiver-child interactions has been conducted in laboratory settings. In the current study, we conducted home observations and investigated whether infants engage in fewer interactions with family members in homes where background TV is more prevalent. We observed 32 infants at the ages of 8, 10, and 18 months in their home environments, coding for dyadic interactions (e.g., parent talking to and/or engaging with the child), triadic interactions (e.g., parent and infant play with a toy together), and infants' individual activities. Our findings revealed that background TV was negatively associated with the time infants spent in triadic interactions, positively associated with time spent engaging in individual activities, and not significantly related to the time spent in dyadic interactions. Apart from the relationship between background TV and individual activity time at 8 months, these associations remained significant even after accounting for families' socioeconomic status. These findings imply a correlation between background TV exposure and caregiver-infant-object interactions, warranting a longitudinal analysis with larger sample sizes.

A Behavioral Analysis of Investor Diversification
(Routledge Journals Taylor & Francis Ltd, 2014) Fuertes, Ana-Maria; Muradoğlu, Gülnur; Öztürkkal, Belma; International Trade and Finance; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
This paper studies the link between individual investors' portfolio diversification levels and various personal traits that proxy informational advantages and overconfidence. The analysis is based on objective data from the largest Turkish brokerage house tracking 59951 individual investors' accounts with a total of 3248654 million transactions over the period 2008-2010. Wealthier highly educated older investors working in the finance sector and those trading relatively often show higher diversification levels possibly because they are better equipped to obtain and process information. Finance professionals married investors and those placing high-volume orders through investment centers show poorer diversification possibly as a reflection of overconfidence. Our analysis reveals important nonlinear effects implying that the marginal impact of overconfidence on diversification is not uniform across investors but varies according to the investor's information gathering and processing abilities.
Beyond the Quest for a Technological Holy Grail: Patterns of Income Inequality and the Household Carbon Footprint in Turkey
(Cambridge University Press, 2025) Gürer, E.; Satloglu, B.; Voyvoda, E.; Erinç Yeldan, A.; 01. Kadir Has University; 03. Faculty of Economics, Administrative and Social Sciences; Economics
Utilizing data on household consumption expenditure patterns and sectorial greenhouse gas emissions, we study the extent of inequality over Turkish households' differentiated carbon footprint incidences. We harmonize the household budget survey data of the Turkish Statistical Institute (TURKSTAT) with production-based gas emissions data from EXIOBASE3 and investigate both the direct and indirect emissions across household-level income strata. Our calculations reveal that the households in the highest income decile alone are responsible for 19.4 percent of the overall (direct and indirect) emissions, whereas the bottom 10 percent of households are responsible for 4.3 percent. We also find that for direct emissions, the per-household average of the highest income decile exceeds that of the lowest income decile by a factor of 11.2. Notably, 87 percent of the indirect emissions budget for the poorest decile is linked to food and housing expenses, underscoring their susceptibility to climate policies. We confer that in designing the net-zero emission pathways to combat climate change, it would not suffice to study the technological transition of decarbonization solely and that the successful implementation of an indigenous environmental policy will ultimately depend upon the socio-economic factors of income distribution strata, indicators of consumption demand, and responsiveness of the individual households to react to price signals. © 2025 The Author(s).

Botnets Unveiled: a Comprehensive Survey on Evolving Threats and Defense Strategies
(Wiley, 2024) Asadi, Mehdi; Jamali, Mohammad Ali Jabraeil; Heidari, Arash; Navimipour, Nima Jafari; Computer Engineering; 05. Faculty of Engineering and Natural Sciences; 01. Kadir Has University
Botnets have emerged as a significant internet security threat, comprising networks of compromised computers under the control of command and control (C&C) servers. These malevolent entities enable a range of malicious activities, from denial of service (DoS) attacks to spam distribution and phishing. Each bot operates as a malicious binary code on vulnerable hosts, granting remote control to attackers who can harness the combined processing power of these compromised hosts for synchronized, highly destructive attacks while maintaining anonymity. This survey explores botnets and their evolution, covering aspects such as their life cycles, C&C models, botnet communication protocols, detection methods, the unique environments botnets operate in, and strategies to evade detection tools. It analyzes research challenges and future directions related to botnets, with a particular focus on evasion and detection techniques, including methods like encryption and the use of covert channels for detection and the reinforcement of botnets. By reviewing existing research, the survey provides a comprehensive overview of botnets, from their origins to their evolving tactics, and evaluates how botnets evade detection and how to counteract their activities. Its primary goal is to inform the research community about the changing landscape of botnets and the challenges in combating these threats, offering guidance on addressing security concerns effectively through the highlighting of evasion and detection methods. The survey concludes by presenting future research directions, including using encryption and covert channels for detection and strategies to strengthen botnets. This aims to guide researchers in developing more robust security measures to combat botnets effectively. Exploring botnets: evolution, tactics, countermeasures. This survey dives into botnets, covering life cycles, communication, and evasion tactics. It highlights challenges and future strategies for combating cyber threats. image

Cannabis Tourists' Perceived Constraints To Engaging in Commercial Cannabis Tourism Overseas: a Comparison of First-Time and Repeat Tourists
(Emerald Group Publishing Ltd, 2023) Wen, Jun; Kozak, Metin; Ying, Tianyu; Advertising; 04. Faculty of Communication; 01. Kadir Has University
Purpose Given the increasing number of tourists exposed to commercially available cannabis, it is important to understand visitors' perceived constraints to cannabis consumption while travelling. This study aims to compare cannabis tourists' perceived constraints between first-time and repeat tourists to gain comprehensive understanding. Design/methodology/approach This study involved 32 conversational field interviews (5-10 min) with Chinese tourists who had smoked cannabis in coffee shops in Amsterdam to identify perceived constraints to engaging in cannabis tourism. The hierarchical constraint model (HCM) informed qualitative data coding using a deductive approach to compare first-time and repeat tourists. Content analysis was conducted manually. Findings Results showed that both tourist groups faced intrapersonal, interpersonal and structural perceived constraints to cannabis consumption. Differences in first-time and repeat cannabis tourists' perceived constraints were explained using the neutralization technique framework and psychological tactics, such as the defence of necessity, claims of entitlement, normal practice and claims of relative acceptability. In addition, social exchange theory was employed to explain why repeat cannabis tourists perceived fewer constraints than first-time tourists. Practical implications Although the current study did not intend to address the importance of cannabis tourism in places where cannabis is commercially available, findings offer empirical guidance for industry practitioners and policymakers regarding cannabis use education, prevention and policy in tourism contexts; related efforts can promote the sustainable development of this tourism market while protecting cannabis tourists' physical and psychological well-being. Originality/value This study makes important theoretical contributions regarding travel constraints in the unique context of cannabis tourism between first-time and repeat tourists. Findings will also enable academics, industry operators, policymakers and local residents of cannabis tourism destinations to better understand how these tourists decide whether to consume cannabis overseas. Differences in these perceived constraints between first-time and repeat tourists are discussed to highlight the dynamic nature of travel constraints.
“Capitalism without Capital” or “Technofeudalism”? Preliminary Thoughts toward a Theory of Knowledge Monopolization
(SAGE Publications Inc., 2025) Orhangazi, Özgür; Economics; 03. Faculty of Economics, Administrative and Social Sciences; 01. Kadir Has University
This article engages with the arguments that the rise of intangible assets, digital platforms, and knowledge monopolies represents either a fundamental transformation of capitalism or the emergence of “technofeudalism.” Drawing from Marxian economic theory, I propose a conceptual framework based on three appearances of knowledge in the economy: commodity, capital, and barriers to entry. Knowledge commodities challenge traditional Marxian value theory because of their infinite reproducibility and near-zero reproduction costs, enabling firms to extract rents rather than directly create new value. Intangible assets increasingly function as capital, intensifying labor exploitation and enabling surveillance and control. Finally, knowledge monopolization reinforces capitalist accumulation and monopolization tendencies by creating barriers to entry. The analysis underscores the persistence of core capitalist logic while highlighting new contradictions posed by digitalization, intangible assets, and intellectual property rights.JEL Classification: B51, O33, O34, L86. © 2025 Elsevier B.V., All rights reserved.

Cartoon Violence and Freedom of Expression
(Johns Hopkins Univ Press, 2008) Keane, David; 01. Kadir Has University
The publication of the "Danish cartoons" generated a continuing conflict between freedom of expression and religious tolerance. The article examines the history of cartoon satire, invoking past examples of racial and religious discrimination in cartoons while emphasizing the important role cartoonists have played in criticizing and checking the exercise of power. The legal implications of the "Danish cartoons" is analyzed through the lens of international human rights law, in particular the concepts of hate speech, racial discrimination and religious defamation. Finally the present movement in the UN towards "cartooning for peace" is promoted.
Change of the Built Environment in Jerusalem During the Late Ottoman Period (1840–1917)
(Routledge, 2025) Alioğlu, E.F.; Architecture; 06. Faculty of Art and Design; 01. Kadir Has University
The establishment of Jerusalem, the holy city of three monotheistic religions on a global scale, dates to 4000 BCE. The city has been settled by various civilizations and has had walls protecting its borders since ancient times. Throughout history, Jerusalem has been influenced by Assyrian, Babylonian, Persian, Hellenic, Roman, Byzantine, Islamic States, and Ottoman periods. The Ottoman Empire first took control of the city in 1517 and then again in 1840, when they regained dominance in Syria and Palestine. In 1841, Jerusalem was separated from the Damascus Province and directly linked to Istanbul. This marked a period of modernization for the Ottoman Empire, following the Tanzimat Edict of 1839. This led to significant changes in legal, administrative, social, economic, political, and zoning fields, transforming the appearance of Ottoman cities. This article will discuss how existing structures were managed in Jerusalem during the final period of Ottoman rule, the regulations for constructing new buildings, the preservation of ancient monuments, and the enforcement of new laws. © 2025 Elsevier B.V., All rights reserved.

Cinema Has Split the Girl's Soul Into Pieces: Scrutinizing Representations of Women in Films From Turkey
(University of Southern California, 2020) Cengiz, Esi̇n Paça; Radio, Television and Cinema; 04. Faculty of Communication; 01. Kadir Has University
The 1980s in Turkey were marked by the emergence of new cinematic forms, including films dealing with issues regarding female subjectivity. This article argues that within the scope of an extensive body of films produced about women in the 1980s, Her Name Is Vasfiye, Aaahh Belinda!, How to Save Asiye, Ten Women, and My Dreams, My Love and You opened up a significant space for discussions about ideological constructions concerning images of women in cinema. By deploying reflexive and fragmented structures, laying bare the ideological operations of voice-over and dubbing, and deploying the screen personas Türkan Şoray and Müjde Ar as cinematic tools, these films offer up a critique of representations of women onscreen, including the trend of “women's films.”
