    Causal Effect of Obesity on the Probability of Employment in Women in Turkey
    (ECONOMICS & HUMAN BIOLOGY, 2023) Pekkurnaz, Didem
    This study aims to investigate the causal effect of obesity on the employment probability of women in Turkey via the instrumental variable approach by using data from the 2018 Turkey and Demographic Health Survey. Obesity prevalence in the area of living and the overweight status of the oldest child, which are the most common types of instruments seen in the literature, are used as instruments. Consistent with the OLS result, the 2SLS estimate indicates that obese women are statistically significantly less likely to be employed when the overweight status of the child is used as an instrument. On the other hand, the statistically significant effect of obesity disappears when the area level obesity prevalence is used as the instrument. In addition, obesity in women decreases the likelihood of employment in the services sector and full-time jobs and employment with social security. Although the results of this study do not indicate the source of the effect found, the presence of a causal relationship for women should not be ignored when the economic burden of obesity for Turkey is considered.

    A Hybrid Monte Carlo Simulation Risk Model for Oil Exploration Projects
    (MARINE POLLUTION BULLETIN, 2023) Balas, Egemen Ander
    A new 3-D Hybrid Monte Carlo Simulation (MCS) Risk Model is proposed in this study. The wind, wave, current, climate change, and tsunami sub-models of the Three-Dimensional Hydrodynamic Transport and Water Quality Model HYDROTAM-3D are interrelated with MCS, to obtain probability distributions for the simulation of environmental conditions. This is the only model that can incorporate the tsunami, storm, and sea level rise risks in oil exploration projects. The spill risk index (SRI) of 50 blue barrels spilled due to a blowout from the rig/port during fuel supply was circa 1 ton/ship as Tier I with an average annual occurrence probability of 1.0 x 10-6. The discharge of 4000 bbls for 6 h was modeled, resulting in the SRI of 546 metric tons from the riser blowout with SRI = 0.2 per meter, indicating a Tier II risk. The mean arrival time of this spill was found by MCS as 145 min.

    Transience and the Modern Turkish Interior
    (2023) Hasirci, Deniz; Ultav, Zeynep Tuna; Sumnu, Umut; AAC-5579-2020
    Despite the expansion of research in modern interiors around the world and a more inclusive dialogue with regards to geography, ultimately, the field is still lacking theory and methods derived from its own specific needs rather than being adapted from architectural research, and a focus on its transient nature that is likely to lead to more impactful research and preservation results. Modern Turkish interiors research have also expanded greatly with individual, as well as projects or research groups like docomomo_tr interiors and DATUMM (Documenting and Archiving Modern Turkish Furniture) that create awareness through various forms of scholarly (documentaries, archival work) and popular (public exhibitions, popular books and magazines, newspaper pieces, and films) interiors research and several struggles are common worldwide, socio-cultural and economic reasons result in a faster pace in Turkey, creating an urgency to implement innovative methods and approaches fitting contemporary prerequisites of the field.

    The Power Bases in Multiplayer Video Games
    (2023) Omerbas, Ali Cagil
    This study deals with how players employ different power relations while playing videogames. Power is a difficult concept to define but it is usually explained with the ability to influence. Social psychologists John French and Bertram Raven's studies have defined five bases for social influence: coercive (based on punishment), referent (based on affection), reward (based on reward), expert (based on expertise) and legitimate (based on agreed regulations) powers. Many other studies have tested their theory in various fields, and it proved to be a lasting one. Researchers conducted studies in areas such as education, business, sports with this theory and obtained meaningful results. However, the power bases of video game players has never been studied, despite the fact that video game studies has already been established as an academic field -with many scholars discussing empowerment through games. This study focuses on measuring the power of a player over another one. There can be two types of such relations: it can either take place among players in an everybody-for-themselves kind of environment - which is called inter-power relations, or it can take place between the members of a team, working together for a common goal. This is called intra power relations. This study demonstrates that expert and reward powers are preferred in inter and intra-power relations, referent being another valid option for teamwork.

    Intelligent Optimization Under the Makespan Constraint: Rapid Evaluation Mechanisms Based on the Critical Machine for the Distributed Flowshop Group Scheduling Problem
    (2023) Wang, Yuhang; Han, Yuyan; Wang, Yuting; Tasgetiren, M. Fatih; Li, Junqing; Gao, Kaizhou
    In the flowshop scheduling literature, the insertion-based neighborhood search method is often considered to obtain high-quality solutions. It will lead to expending extensive computational effort when evaluating the objective function. Rapid evaluation methods based on Taillard's acceleration can reduce the time complexity of function evaluation. However, existing rapid evaluation methods cannot be applied directly to the distributed flowshop group scheduling problem (DFGSP), especially to minimize the total tardiness time objective. Thus, we first proposed two theorems and their proofs based on the critical machine. Then, two rapid evaluation methods based on these theorems are proposed to accelerate the evaluation of the objective. Considering the multiple coupled sub-problems in the DFGSP, we proposed a cooperative iterated greedy algorithm (CIG) combining two rapid evaluation methods, in which intergroup and intra-group neighborhood search strategies are proposed to enhance the search depth and breadth. Comprehensive statistical experiments show that computational effort is extensively decreased in the calculation of total tardiness time, and the CIG algorithm significantly outperforms the eight compared algorithms.& COPY; 2023 Elsevier B.V.

    The Influence of Different Sugammadex Doses on Neural Tube Development in Early-Stage Chick Embryos
    (2023) Ayhan, Asude; Efe, Ekin; Fidan, Pinar A.; Efe, Oguzhan E.; Ates, Eylem Gul; Sahinturk, Fikret; Ayhan, Selim; 0000-0002-6166-2601; 0000-0001-6955-9839; 0000-0002-3243-7843; 0000-0003-3047-0305; 0000-0002-0471-3177; 37565787; HGE-9282-2022; AAJ-2057-2021; AAJ-4728-2021; W-7908-2019; ABG-5365-2020; AAI-7972-2021
    Background: Sugammadex is a modified gamma-cyclodextrin that has been developed with the goal of reversing the steroidal neuromuscular blocking agents. The aim of the present study is to investigate the effects of different sugammadex doses on embryologic and neural tube development in an early-stage chick embryo model. Methods: A total of 100 specific pathogen-free, fertilized domestic chicken eggs were randomly divided into five groups (n = 20, each), and placed in an automatic cycle incubator. The eggs in the "control (C)" group were incubated without administration of any drug till the end of the experiment. Subblastodermic administration of 0.9% NaCl as vehicle control (VC) and different doses of sugammadex solutions prepared with the latter [2 mg/mL (LD), 4 mg/mL (MD), 16 mg/mL (HD)] were performed at 30 hr of incubation. All embryos were removed from the eggs at 72 hr when they were expected to reach Hamburger-Hamilton (HH) stages 19-20, then they were fixed, and evaluated histo-morphologically. Results: Embryonic development was not observed in 11 eggs (1 in C, 1 in VC; 3 in LD, 3 in MD, and 3 in HD). All the developed embryos were compatible with the HH stages 19-20. A neural tube closure defect was detected in one embryo in the HD group. No statistically significant difference was found between the groups in terms of embryonic and neural tube developments. Conclusions: No significant association was found between the drug and adverse outcomes; however, a trend with dosing was seen. Further studies are required before conclude on safety and extrapolate these results to human beings.
