(New York Business Global LLC, 2023) Kulahcioglu, Burcin; Ufuktepe, Unal; Kalampakas, Antonios
We examine a discrete-time host-parasitoid model incorporating simultaneously an Allee and a refuge effect on the host. We investigate existence of a positive fixed point, local asymptotic stability, global stability of the fixed points and bifurcations. Numerical examples are given for verification of the theoretical results and we compare the model with existing data from the literature. 2020 Mathematics Subject Classifications: 92D25, 39A30, 92D30
A Stochastic Multi-Objective Optimization Approach to Cooperative Task and Route Planning for Heterogeneous UAVs in Uncertain Combat Environments
(Springer Nature, 2026) Güngör, Göktuğ; Yıldırım, Gonca; İşleyen, S. Kürşat; Kazan, Cem
This paper addresses the coordinated task assignment and route planning for a fleet of heterogeneous unmanned air vehicles (UAVs) operating in a stochastic threat environment. Each UAV is capable of engaging and destroying designated targets, while enemy air defenses pose risks of UAV losses based on specified survival probabilities. The study aims to minimize mission tardiness within a fixed time horizon and maximize cumulative mission rewards by neutralizing the highest number of targets while minimizing UAV losses. We first formulate the problem as a stochastic, multi-objective mixed-integer linear program defined on a graph, integrating task scheduling, timing, and connectivity constraints to simultaneously optimize UAV routes and target assignments. For small-scale instances, this formulation can be solved optimally. However, the problem’s NP-hard, combinatorial nature renders exact methods impractical for larger instances. To address this, we develop a novel two-stage heuristic, combining simulated annealing and genetic algorithms. In the first stage, simulated annealing generates a robust initial task allocation common to all scenarios. In the second stage, a genetic algorithm refines the routes and assignments independently for each scenario. A custom scenario generator was developed to vary survival probabilities, target densities, distance metrics, and UAV capacities to rigorously test solution quality. Computational experiments demonstrate that the proposed heuristic produces high-quality solutions across various settings within tractable time frames, offering decision makers a practical tool to plan UAV-based airstrike operations under uncertainty.

(MDPI, 2021) Ergoz Karahan, Ebru; Gocer, Ozgur; Gocer, Kenan; Boyacioglu, Didem; Goecer, Oezguer; Goecer, Kenan; Karahan, Ebru Ergöz; Ergoez Karahan, Ebru
Despite its well-known potential to reduce energy use, the inquiry of whether vernacular architecture prompts its occupants to have energy-saving behavior has been neglected. This paper aims to investigate the influence of vernacular houses on the behavior of their occupants and other parameters affecting occupant behavior. Along with site observations, 117 surveys including multiple choice and open-ended questions were conducted with households living in vernacular houses and new houses in the historical settlement, Behramkale (Assos). A principal component analysis was conducted for the whole sample to determine whether there is a relationship between energy saving occupant behavior and energy use, household, and housing characteristics. Then further analyses were performed to explore the differences in descriptive properties of occupants. Household characteristics were found to be associated with occupant behavior. The females and married people tended to show more energy-saving behavior and sought to use their houses in more environmentally friendly ways. The older people were more likely to show no-cost energy-saving behavior. The households with high income and high-level education tended to invest in energy-efficient appliances but consumed more energy than other households. Besides the effects of household characteristics, historical heritage, and landscape values specific to the area influenced occupant behavior. Vernacular houses enabled the households to behave in a certain way and to continue the traditional daily habits related to sustainable, energy-saving behaviors.
Analyzing Cost Efficiency and Project Scope in Post-Disaster Housing: Reconstruction Cases of Toki in Türkiye
(MDPI, 2025) Geylani, Ozlem
The Mass Housing Administration of T & uuml;rkiye (TOKI) operates as the primary public organization responsible for delivering extensive affordable housing throughout T & uuml;rkiye while ensuring disaster resilience. The recent decades of earthquakes and environmental hazards in T & uuml;rkiye have necessitated extensive post-disaster reconstruction initiatives nationwide. In response, TOKI has completed numerous disaster housing projects across the country through an integrated infrastructure framework supporting community recovery. This study presents an extensive statistical evaluation of 664 disaster housing projects constructed by TOKI across 40 provinces. Specifically, a quantitative analysis is conducted on 434 disaster housing projects for which detailed financial data are available. This research examines differences in construction costs between urban mass housing developments and rural village settlements, particularly focusing on the integration of functional structures such as schools, mosques, commercial units, and barns. Although mass housing projects require significantly larger total budgets due to their extensive scale, statistical analysis reveals no significant difference in per-unit construction costs between mass housing and village housing projects. Regression analysis indicates that incorporating barns increased per-unit construction costs, while the presence of schools and mosques significantly decreases these expenses. The findings of this research provide critical insights into the economic and functional factors influencing disaster housing reconstruction in T & uuml;rkiye and offer practical recommendations for improved planning, resource management, and community reconstruction based on an evaluation of functional structures.
Applicability of a Digitalization Model Based on Augmented Reality for Building Construction Education in Architecture
(Emerald Group Publishing Ltd, 2023) Guray, Tayibe Seyman; Kismet, Burcu; Seyman Guray, Tayibe
Purpose The purpose of this paper is to introduce a digitalization model (DM) for building construction courses in architectural education as a response to the recent emerging technologies in the era of digital transformations. This DM is developed and applied through augmented reality (AR) technologies to boost perception, understandings and ability to solve building construction details. Design/methodology/approach Based on a thorough review of recent technologies like AR, virtual reality (VR), building information modelling (BIM) and their applications in architectural education, the methodology involves the generation of a model, its application and evaluation. The model is based on the integration of BIM and AR which is applied into a third year "Building Construction Project" course. Each student has designed a residential building and accordingly prepared the construction drawings by adapting the DM. An online survey -based on Technology Acceptance Model - is conducted to evaluate the DM by quantitative data analysis from SPSS and Excel. Findings The key findings of the study include the following items: determination of the proper digital tools, the definition of the steps and workflow based on the building project phases to develop construction drawings and define precise details effectively. By the help of this, the DM is generated and applied. According to the survey and results, the DM which involves BIM-based AR is considered as beneficial, highly motivating and providing better perception on construction details. Originality/value Implication of AR/VR technologies is frequently seen in design studios, whereas building construction courses state its traditional approach. However, there is a huge potential in the digitalization of building construction education by increasing the perception of students together with the increased level of communication. The study aims to close the gap of digitalization by proposing a DM, which brings a systematic approach considering each phase of building construction project as conceptual, schematic, design development and construction documents by using BIM integrated AR. Moreover, the novel model specifically brings a new approach by generation of QR codes for construction details to embed videos or simulations into the two-dimensional drawing sheets. Furthermore, the DM proposes a new approach to satisfy emerging needs and requirements of the Architecture Engineering Construction industry.
Applying Entropy Weighting and 2-Tuple Linguistic T-Spherical Fuzzy MCDM: A Case Study of Developing a Strategic Sustainability Plan for Istanbul Airport
(MDPI, 2024) Mizrak, Filiz; Polat, Levent; Tasar, Sezin Acik
This study presents a novel sustainability plan tailored for Istanbul Airport, leveraging advanced decision-making methodologies to address the urgent need for sustainable practices in aviation. By integrating the entropy weighting and 2-tuple linguistic T-spherical fuzzy multi-criteria decision-making (MCDM) models, the study offers a comprehensive approach to evaluating and prioritizing sustainability criteria based on expert input from 12 professionals. The novelty of this research lies in its unique combination of advanced MCDM techniques with cutting-edge technologies, including IoT-enabled monitoring systems, digital twin models, blockchain-based sustainability reporting, and carbon capture initiatives, tailored specifically for large-scale airport operations. The study develops a phased implementation roadmap comprising three stages: (1) a short-term focus on energy efficiency and renewable energy infrastructure, achieving significant cost reductions within a 3-7.5-year payback period; (2) medium-term initiatives integrating IoT and digital twins to enhance operational efficiency; and (3) long-term measures incorporating carbon capture and blockchain for transparency and compliance. Key implementation steps include upgrading energy systems, deploying IoT sensors, creating digital replicas of airport infrastructure, and establishing regulatory and stakeholder collaboration frameworks. This research contributes a replicable framework for airports worldwide, bridging theoretical models with actionable solutions.
Attenuated Rightward Hemispheric Asymmetry in ADHD: Structural MRI Evidence from a Normalized Asymmetry Index and Its Association with Cognitive Performance
(Frontiers Media SA, 2026) Tarlaci, Sultan; Cinaroglu, Metin; Yilmazer, Eda; Ulker, Selami Varol
Background Altered hemispheric asymmetry has been proposed as a potential neurodevelopmental feature of Attention-Deficit/Hyperactivity Disorder (ADHD). However, findings remain inconsistent, and the functional relevance of structural asymmetry patterns is not well established. This study examines volumetric and cortical-thickness asymmetries across cortical and subcortical regions in children and adolescents with ADHD compared to typically developing controls and evaluates their association with objective cognitive performance. Methods Forty participants with ADHD and 30 age- and sex-matched controls underwent high-resolution T1-weighted MRI. Bilateral regional volumes and cortical thickness were quantified using the volBrain pipeline, and asymmetry indices (AI = [R-L]/[(R + L)/2]) were computed for lobar and subcortical structures. Group differences were assessed using independent t-tests. Within the ADHD group, associations between asymmetry indices and MOXO-d-CPT performance (Attention, Timing, Impulsivity, Hyperactivity) were examined using Pearson correlations with correction for multiple comparisons. Results ADHD participants showed significantly reduced rightward asymmetry in frontal lobe volume, cerebellar hemispheres, caudate, putamen, and amygdala (ps < 0.05). Cortical-thickness asymmetry was also diminished in the frontal and parietal lobes and the anterior cingulate cortex. Temporal and occipital asymmetries were preserved. Within the ADHD group, greater rightward frontal and ACC thickness asymmetry correlated with better attention performance (r = 0.45 and 0.40), rightward parietal asymmetry associated with more accurate timing (r = 0.38), reduced rightward IFG asymmetry related to greater impulsivity (r = -0.42), and amygdala asymmetry correlated with lower hyperactivity (r = 0.36). Conclusion Children with ADHD exhibit a consistent attenuation of typical right-hemisphere dominance across frontal, striatal, cerebellar, and limbic systems. These altered asymmetry patterns are meaningfully associated with attentional control, timing accuracy, impulsivity, and hyperactivity, suggesting that hemispheric imbalance may serve as a structural may represent a neurodevelopmental characteristic associated with ADHD. Findings support models emphasizing right-hemisphere developmental lag and highlight hemispheric asymmetry as a clinically relevant dimension of ADHD neurobiology.
Can Commercial Buildings Cope with Australian Bushfires? An IAQ Analysis
(Ubiquity Press Ltd, 2021) Brambilla, Arianna; Candido, Christhina; Sangiorgio, Marco filippo; Gocer, Ozgur; Gocer, Kenan
The Australian 2019/20 summer witnessed an extraordinary bushfire season characterised by unprecedented duration, geographical reach and impact. The aftermath of the bushfires includes increased health-related implications on people due to short and long exposure to poor air quality. The current advice from the Australian authorities in such events is to remain indoors, as it was assumed indoor air quality (IAQ) is healthy. This paper examined that assumption and presents the case study of an office building in Canberra subjected to the 2019/20 bushfires, responding to the need of understanding the ability of air-conditioning buildings to cope with such unprecedented and extreme weather events. Measured data for indoor concentration of CO2, PM10 and PM2.5 recorded a prolonged period of concerning levels, as well as extreme concentration peaks. This poses a significant risk to the occupants' health. The values showed peaks up to 12 times higher for PM10 and 24 times higher for PM2.5 than the recommended critical thresholds. The infiltration factor and protection performance analysis suggest that old filtering systems and low airtightness levels are not optimal in protecting the indoor environment from outdoor air pollutants.
Cd Dopant Effect on Structural and Optoelectronic Properties of TiO2 Solar Detectors
(Springer, 2021) Ilhan, Mustafa; Koc, Mumin Mehmet; Coskun, Burhan; Erkovan, Mustafa; Yakuphanoglu, Fahrettin
Al/n-Si/Ti1-xO2CdxO/Al photodiodes were produced using sol-gel and spin coating methods where CdO dopant was applied on different concentrations (x = 0.0; x = 0.01; x = 0.05; x = 0.10). Cd dopant effect upon structural, optical, photodiode and electrical properties was assessed. Scanning electron microscope and energy-dispersive spectra were used in the structural investigation. Optic properties were assessed using UV-Vis spectroscopy and bandgap energies of the photodiodes were calculated which were found to be between 3.25 and 3.36 eV. Increased bandgap energy was observed with increased CdO doping rate. Photodiode properties were assessed under varying daylight illuminations. Barrier height, ideality factor, dark current, linear dynamic rate, photosensitivity, photoresponsivity of the photodiodes were calculated. Electrical properties of the Al/n-Si/Ti1-xO2CdxO/Al photodiodes were calculated where conductance-voltage and capacitance-voltage plots were obtained. Corrective conductance-voltage and corrective capacitance-voltage graphs confirm that the electrical properties of the photodiodes depend on AC signal frequency. Frequency-dependent electrical characteristics were attributed to the density of interface states which were found to be between 10(11) and 10(12). Decreased density of interface state was found for increased AC signal frequency.
Changes in Anthocyanin Pigments, Trans-Resveratrol, and Colorimetric Characteristics of Fondillón Wine and Other “Monastrell” Wines During the Aging Period
(Springer Science and Business Media Deutschland GmbH, 2023) Uysal, R.S.; Issa-Issa, H.; Esther, E.; Carbonell-Barrachina, A.A.; Sendra, Esther
The studied red wines, which are Fondillón, reserva, crianza, and young, are prepared from exclusive “Monastrell” grapes, and protected under the Alicante Denomination of Origin (Alicante, Spain). The objectives of the present study were (i) to show the effect of aging period on the amount of anthocyanin pigments, trans-resveratrol, and the colorimetric characteristics (color intensity, color density, and tonality) of Fondillón and other Monastrell wines (young, crianza, and reserva) which have different aging periods, and (ii) to propose a new traceability method for the determination of the Fondillón originality. Identification of anthocyanin compounds and determination of trans-resveratrol content were performed using LC–MS/MS. Correlation analysis was performed among anthocyanin compounds and color parameters. A sharp decrease in the anthocyanins content was observed in Fondillón wine. Besides, statistically significant changes were found in all colorimetric parameters between young and Fondillón samples. A significant change from red hue to brick red/yellow hue was observed between the colors of young and Fondillón wines, respectively. A significant decrease in the content of trans-resveratrol was also observed as a result of the aging period of these “Monastrell” wines. In this study, anthocyanin compounds of Fondillón wine were identified for the first time and their effects on the colorimetric parameters of the wine were revealed. Consequently, the authenticity of Fondillón wines can be determined by monitoring of anthocyanin compounds and trans-resveratrol. © 2023, The Author(s).
Charge and Thermal Transport Properties of Undoped and Doped T L + (IN3 + X22−)− Ternary Dichalcogenides with a Reduced Dimensionality: Perfect Candidates for Thermoelectric Applications in the Mid-Temperature Region
(Institute of Physics, 2025) Yavuz, M.F.; Gökçe, S.; Gür, E.S.; Mammadov, T.G.; Najafov, A.I.; Salehli, F.; Akşit, M.; Yu Seyidov, Mirhasan
The present work focuses on a comprehensive investigation of charge and thermal transport properties of thallium-indium-based ternary dichalcogenides with a common chemical formula of T l + ( I n 3 + X 2 2 − ) − where X denotes tellurium, selenium or sulfur atoms. Two compounds in the one-dimensional chain form, including pristine TlInSe<inf>2</inf> and Fe-doped TlInTe<inf>2</inf> as well as a hybrid material constructed from the two-dimensional TlInS<inf>2</inf> layered semiconductor diluted with TlFeS<inf>2</inf> at % 0.7, have been successfully grown using the Bridgman-Stockbarger technique. X-ray powder diffraction, scanning electron microscopy and energy-dispersive x-ray spectroscopy measurements were performed to characterize the local structure and chemical composition features of all prepared compounds. A strong anisotropy in the charge-carrier transport properties of the samples was observed from dc - and ac - electrical conductivity measurements made in directions parallel and perpendicular to the layers/chains. This is a fundamental property for realizing high thermoelectric performance in semiconducting materials. As a result, extremely large Seebeck coefficients were revealed upon experimental investigations of the thermoelectric properties of T l + ( I n 3 + X 2 2 − ) − samples over a wide temperature range between ∼100 K and ∼800 K. The first-principles density functional theory (DFT) and Boltzmann transport equations were employed to investigate the thermal transport properties of the compounds studied at the atomic scale. A specific interaction between the thallium cation and the sulfur anion was observed in the DFT computation scheme. The developed interaction (more electrostatic than a much weaker van der Waals one) enhances the charge carrier effective mass via flattening of the electronic bands near the band edges and this can give a new path towards Seebeck coefficient enhancement in the traditional mid-temperature range. © 2024 IOP Publishing Ltd.

Comment on “Charged Zipoy-Voorhees Metric in String Theory”
(Academic Press Inc., 2025) Gürtuğ, O.; Halilsoy, M.; Mangut, M.
In a recent paper by Yunusov et al. (2025) it is claimed that the charged Zipoy–Voorhees (ZV) metric found in a paper by Gurtug et al. (2022) does not satisfy the Einstein–Maxwell (EM) equations. It is our aim in this comment to show that this claim is invalid. Nevertheless, their stringy EM extension of the ZV metric remains valid. © 2025 Elsevier Inc.
Comparing Cognitive Behavioral Therapy and Ericksonian Hypnotherapy for Obsessive–Compulsive Disorder: A Randomized Controlled Trial
(Routledge, 2026) Çınaroğlu M.; Yılmazer E.; Odabaşı C.; Ülker S.V.; Tan S.; Hızlı Sayar G.; Çınaroğlu, Metin; Sayar, Gokben Hizli; Tan, Selin; Ülker, Selami Varol; Yılmazer, Eda; Odabaşı, Cemre; Hızlı Sayar, Gökben
Obsessive–Compulsive Disorder (OCD) is a chronic condition that often responds well to Cognitive Behavioral Therapy (CBT), though many patients fail to achieve full remission. Ericksonian Hypnotherapy (EH) has been proposed as a promising alternative. This randomized controlled trial compared the efficacy of CBT and EH against a waitlist control in 99 adults with OCD. Participants received 12 weekly online therapy sessions. Outcomes were assessed at baseline, mid-treatment, and post-treatment using the Padua Inventory-Revised, Yale–Brown Obsessive Compulsive Scale–Self-Report (Y-BOCS-SR), and Beck Anxiety Inventory (BAI). Both CBT and EH led to large, statistically and clinically significant reductions in OCD symptoms compared to waitlist. CBT was more effective for compulsive behaviors such as washing, while EH produced greater reductions in obsessive rumination and general anxiety. No serious adverse events occurred. These findings suggest that EH is a viable and comparably effective treatment to CBT, with distinct therapeutic benefits. EH may offer a particularly useful option for patients with obsession-dominant symptom profiles or comorbid anxiety. © 2026 International Journal of Clinical and Experimental Hypnosis.
Comparison of Domino Transplantation with Two-Way Paired Exchange and Normal Transplantation: Acute Rejection, Surgical Complications, and 5-Year Survival Outcomes
(Springer, 2025) Huseynov, Amil; Cicek, Sevim Nuran Kuslu
Background Domino kidney paired donation and Two-Way Paired Exchange have emerged as vital strategies to expand the donor pool in renal transplantation, especially for patients facing ABO or HLA incompatibilities. Despite their potential benefits, concerns remain regarding immunological risks, infectious complications, and long-term graft survival. Methods In this retrospective cohort study conducted at Medicana Transplant Center, 980 adult kidney transplant recipients were categorized into three groups: Domino (n = 144), Two-Way Paired Exchange (n = 350), and Normal Transplant (n = 486). Baseline characteristics, acute rejection rates, and surgical or infectious complications were collected, alongside data on 1-year and 5-year patient and graft survival. Statistical analysis included Kaplan-Meier survival curves and Cox proportional hazards modeling for independent predictors of graft outcomes. Results The Domino group had the highest 1-year acute rejection rate (17.4%) compared to Two-Way Paired Exchange (4.3%) and Normal Transplant (3.7%), yet 1-year graft survival rates remained comparable (92%, 95%, and 96%, respectively; p = 0.271). Infectious complications were more frequent in the Domino group (25%) than in others (p < 0.01). Extended follow-up to 5 years indicated no statistically significant difference in overall graft or patient survival among the three groups (log-rank p = 0.197), despite a trend toward lower 5-year graft survival in the Domino group. Donor-specific antibodies and higher HLA mismatches independently predicted acute rejection. Conclusions Domino transplantation, while associated with higher immunologic challenges, achieves acceptable short-term and 5-year outcomes akin to Two-Way Paired Exchange and Normal Transplant. Careful immunosuppressive strategies, vigilant monitoring, and collaborative protocols are integral for optimizing long-term success in high-risk transplant scenarios.

Desire and Absence in Rimini Protokoll's Conference of the Absent: A Lacanian Analysis of Audience Interviews
(John Wiley and Sons Ltd, 2026) Akıncı Ö.; Sümerkan H.H.; Akinci, Ozgul; Sumerkan, Hazal Hamarat
This paper explores the Conference of the Absent experience, a participatory theater piece produced by Rimini Protokoll, through a Lacanian psychoanalytic perspective. Drawing on semi-structured interviews with audience members who participated in the performance, it seeks to analyze the anxieties and resistances around performing, as well as how these experiences are retrospectively narrated and made sense of. Conference of the Absent is considered as a reconfiguration of the spectator-performer relation in a manner analogous to processes of subject formation in Lacanian psychoanalysis. The paper, thus, discusses how the performance destabilizes scopic mastery, repositions the voice as the central medium of subjectivation and situates the participants in a new system of meaning. Drawing from the audience interviews and analysis of the theatrical design, it is argued that the audience's engagement is less an act of personal agency than a pre-orchestrated response conditioned by the performance's dramaturgical design. This paper contributes to theater audience research by offering psychoanalytical theory as a methodological tool in understanding the workings of spectatorship in a participatory theater setting. © 2026 John Wiley & Sons Ltd.
Developing a Building-Scale Circularity Indicator Through Fuzzy Analytical Hierarchy Process and Gini Index-Based Circularity Calculation Methods
(Taylor & Francis Ltd, 2026) Kismet, Burcu; Colakoglu, Meryem Birgul
Circular economy (CE) aims to achieve sustainable development by optimizing resource efficiency through innovative system designs. The built environment plays a crucial role in this transition, yet the absence of standardized indicators hinders effective circularity assessment. This study introduces a structured building-scale circularity indicator (BuCI) to support industry and academia in evaluating buildings' circularity levels and facilitating the shift towards a circular built environment. Based on a thorough review of CE, the methodology involves the generation of a model, its implementation on a selected case study and evaluation. The proposed model integrates the shearing layer and building lifecycle concepts to establish a measurement framework with defined criteria and key performance indicators. Fuzzy analytical hierarchy process and Gini index are used to formulate circularity calculation. Then, the BuCI is implemented on three different case studies, two steel and one reinforced concrete buildings. CS1 and CS2 reached 60% circularity level, thanks to the material advantages and certain design principles such as modularity, disassembly and flexibility, whereas CS3 calculated as 31.05% circular due to material and design decisions. The study contributes to the field by introducing a novel indicator for the industry, academia and authorities to accelerate the circular transition. For future studies, it is suggested to integrate cost and cultural heritage related criteria.

(Elsevier, 2025) Mizrak, Filiz; Mizrak, Kagan Cenk; Akkartal, Gonca Reyhan
The purpose of this study is to develop a comprehensive decision-making framework that airlines can use to strategically select new destinations, demonstrated here with a case application for Turkish Airlines. Addressing the complexities of route expansion, the study integrates the Entropy weighting method with the 2-Tuple Linguistic T-Spherical Fuzzy Decision by Opinion Score Method (2TLTS-FDOSM) to evaluate potential destinations across critical criteria, including market demand, economic impact, and regulatory environment. Data were collected from industry reports, expert evaluations, and publicly available aviation metrics to support a thorough and adaptable analysis. Findings from the Turkish Airlines case reveal San Antonio, TX (SAT), Portland, OR (PDX), and Nashville, TN (BNA) as top-ranked destinations, each offering distinct economic and operational benefits. This study contributes to aviation management literature by presenting a versatile, data-driven framework that can guide route selection for carriers in competitive markets. The framework's ability to balance quantitative and qualitative insights underscores its potential for broader application in network planning, promoting sustainable growth within the aviation industry.
Differences in Occupants' Satisfaction and Perceived Productivity in High- and Low-Performance Offices
(MDPI, 2019) Gocer, Ozgur; Candido, Christhina; Thomas, Leena; Gocer, Kenan
This paper reports the results from a dataset comprising 9794 post-occupancy evaluation (POE) surveys from 77 Australian open-plan offices. This paper specifically focuses on a sub-set of 20 offices (n = 2133), identified from ranking 10 offices each, with the least (n = 1063) and highest (n = 1070) satisfaction scores, respectively. The satisfaction scores were evaluated on the basis of seven factors (i.e., building/office aesthetics and quality, thermal comfort and indoor air quality, noise distraction and privacy, personal control, connection to outdoor environment, maintenance and visual comfort, and individual space). Using the POE survey data from 20 offices, regression analyses and two-way ANOVA tests were carried out to understand the differences in occupants' satisfaction and perceived productivity arising from open-plan offices. According to the statistically significant regression analyses results, it was identified that building/office aesthetics and quality (beta = 0.55, p < 0.001) and noise distraction and privacy (beta = 0.33, p < 0.001) were the two strongest predictors contributing perceived productivity in low-performance offices. Two-way ANOVA test results for the 10 high-performance offices indicate that the perceived productivity was strongly associated with the office's physical configuration, the employees' working experience, and the working hours at that office.
