• Waste production from schools changes depending on the level of institutions. • High rate of positive answers but unsuccessful sorting indicate lack of practice. • Recycling capture rates do not differ significantly between school types. • There is a strong positive correlation between capture rates of some recyclables. • The success of recycling is higher if it is is supported with specific programmes. In this study, the waste generation at the educational institutes chosen from four different levels (kindergartens, primary, secondary and high schools) in Istanbul was measured on-site and the contents of the waste thrown into the recycling bins were determined to specify capture rates. Separation and weighing processes were performed at 16 spots in high schools, 12 spots in secondary schools, 7 spots in primary schools and 7 spots in kindergartens. A survey was conducted to determine the students' awareness of recycling in these schools. It was revealed that the wastes produced from educational institutes are organics (36.4 %), paper (24 %), plastics (14.4 %), glass (8.1 %), metals (4.8 %) and miscellaneous (12.3 %). The survey results indicate that 93 % of the participants think recycling is important, 71 % of them throw their waste into suitable waste bins and 59 % of them know the location of the recycling bins. At the primary school level, a very high rate of paper waste (92.3 %) was reported in plastic bins while plastic waste collected in these bins remained only 5.7 %. It was also seen that glass waste captured in glass bins and metal waste in metal bins remain very low rates (20.9 % and 29.2 %, respectively) at the secondary school level. At the high school level, it was determined that the most commonly captured wastes in glass, plastics and paper bins are glass (47.5 %), plastic (43.2 %) and paper (32.5 %), respectively. Correlation analyses indicated a high positive correlation (p < 0.05) between particular types of waste. [ABSTRACT FROM AUTHOR]

Literature on mobility justice suggest that socially disadvantaged people experience uneven access to movement. The theme of diversity in terms of gender and its interplay with mobility and leisure have attracted some scholarly attention. However, research into transgender and gender diverse mobilities and its impact to leisure access remains limited, particularly from non-Western perspectives. This paper endeavors to fill this gap by investigating transgender and gender diverse mobilities in Istanbul, Turkey. Drawing upon 49 qualitative interviews with gender diverse and transgender public transport users in Istanbul, this study contributes to a scholarly discussion exploring the relationship between gender diversity, mobility, and their access to leisure. As such, it furthers the field of gender-oriented leisure. Transgender and gender diverse individuals continue to face significant issues, such as violence, discrimination, and harassment, when using public transport. Based on the experiences of the respondents, this paper concludes that driver training and education, and proactive educational messaging around gender minorities in public spaces could significantly improve the comfort and safety of transgender and gender diverse public transport users.

Large-scale high-rise architecture projects have been central to the rise of the construction industry in Turkey in recent years. This vertical escalation, however, has not been received without dissidence. Scholars, activists, journalists and officials with different viewpoints have participated in media debates regarding the reasons and consequences of this transformation. In these discussions, stakeholders have raised various environmental, cultural and ethical concerns that the vertical organisation of cities generate. Focussing on juxtapositions of Izmir and Istanbul in debates on urban verticality in the city of Izmir, Turkey's third most populated city, the paper examines how such comparisons with Istanbul, where the recent urban neoliberal transformation is experienced most intensely, have been mobilised to oppose vertical expansion. The paper argues that as a result of the recent centralisation of the Turkish economy around construction, the hyper-visibility of skyscrapers and the concentration of the urban transformation generated by the Turkish construction industry in Istanbul, skyscrapers have become materialised symbols of Istanbul's integration into global capitalism, neoliberal urbanisation, and the difference between Istanbul and other urban centres in Turkey. This example establishes urban verticality as a discursive axis at which urban centres outside of the Global North establish their difference from each other. [ABSTRACT FROM AUTHOR]

In this paper, I discuss how the earthquake risk is exploited by 'disaster capitalism', in order to convert Istanbul to a massive construction site. The shock of the 1999 Marmara Earthquake has been effectively used by the neoliberal market and government as 'a shock therapy' to implement a construction‐led development model for Turkey and to favour the construction sector by introducing new incentives, exceptional rights and interventions, which otherwise might be challenged. The current Turkish government justify the ongoing massive urban transformation and new mass housing projects as an improvement of the housing stock to make residential buildings stronger and more resilient to earthquakes. However, areas actually under earthquake risk do not match the areas that are officially declared under disaster risk by the government. The Disaster Law #6306 that granted the government the absolute right to expropriate land based on the justification of 'protecting residents against earthquakes and other natural disasters' was applied in a selective way to seize valuable land in Istanbul. In the paper I explore how the disaster was quickly converted to an opportunity for economic growth. To do that I introduce stories of three different neighbourhoods in Istanbul, namely Moda, Tozkoparan and Fikirtepe, each of which experience the ongoing massive urban transformation differently based on the land value of the neighbourhoods, class position of the residents, and residents' capacity to organise in order to protect their rights. I describe, how disaster capitalism is lived and experienced differently in these three neighbourhoods. Although the massive construction projects are indifferent to life's sustainability, those projects are justified as interventions in terms of public health and safety through making housing resilient to earthquakes. I critically discuss how in each case biopolitics presents disaster capitalism's massive urban transformation projects as a manifestation of liveliness. [ABSTRACT FROM AUTHOR]

The YK 1 shipwreck, found at Yenikapı, Istanbul, is one of 37 shipwrecks dating to the medieval era. This paper describes the studies and the processes which were conducted to conserve the YK 1. Firstly, the level of physical and chemical degradation of the wood from the YK 1 was examined, which revealed that the wood was highly degraded. Therefore, PEG 2000 was chosen for the impregnation process before vacuum freeze-drying. In addition, the ASE values confirmed that the PEG 2000 impregnation and vacuum freeze-drying method together were successful in conserving the YK 1, with values higher than PEG 2000 impregnation and vacuum freeze-drying methods alone. The concentration of the PEG solution in the tank was monitored throughout the impregnation process. Following this, samples taken from the wood cores were analysed using FTIR to evaluate the effectiveness of the impregnation process. Finally, SEM was used to examine the effectiveness of the PEG 2000 impregnation and vacuum freeze-drying method. The SEM images showed that the PEG 2000 was uniformly distributed, and the wood had no deformation after freeze-drying. [ABSTRACT FROM AUTHOR]

Introduction: Residency training may lead to the development of depressive conditions with possible academic and professional consequences. We determined the levels of depression in resident medical doctors (RMDs) and assess the factors influencing depression. Methods: This prospective cross-sectional questionnaire study was conducted on RMDs working in tertiary research hospital in İstanbul. Participation in the study was voluntary. A questionnaire was distributed to the RMDs participating in the study, and the Beck Depression Inventory-II (BDI-II) was used to measure depression levels. This study was presented as a paper at the 5th Eurasian Congress on Emergency Medicine and 12th Turkish Emergency Medicine Congress, November 10-13, 2016 (Antalya, Turkey). Results: A total of 161 RMDs were included in the study (participation rate: 68.8%). Of the RMDs, 65 (40.4%) had depressive symptoms (BDI-II >13). An exploratory analysis of possible risk factors showed that working night shifts, length of residency, and department in which the resident worked were factors for the development of depressive symptoms. There was no association between BDI-II scores and age, gender, marital status, number of children, living alone, recent loss of a loved one, presence of chronic illness, diagnosis of depression, or use of antidepressant medication. Conclusion: There is a high prevalence of depressive symptoms among RMDs, especially night workers, who have less experience in their residency. Active assessment of these RMDs to evaluate their depressive symptoms is important. Preventive measures and educational programmes to improve working conditions need to be reviewed.

Earthquakes have caused catastrophic results in cities since the beginning of settled life, and the cumulative experience of these events has indicated that the lack of seismic resilience brings enormous economic losses and threatens human life. Consequently, the importance of seismic risk mitigation of earthquake-prone structures has arisen to reduce the primary and secondary losses resulting from seismic events in the last decades as developments in the earthquake engineering field occur. The first step for ensuring seismic resilience is the identification of risky buildings, which is a difficult challenge for metropolises like Istanbul since the building stock consists of over a million buildings. Applying code-based detailed assessments to so many buildings is not practical in terms of time and cost. Moreover, the current code-based detailed assessment methodologies such as Provisions for the Seismic Risk Evaluation of Existing Buildings under Urban Renewal Law (2019) and Turkish Building Earthquake Code (2018) provide discrete predictions for existing buildings as either risky or non-risky or satisfying life safety/controlled damage or not. However, a ranking system based on a reliable and realistic risk classification to prioritize the buildings is needed. Therefore, as a pilot project, nearly 23,000 reinforced concrete buildings in 37 different districts of Istanbul have been investigated by Istanbul Metropolitan Municipality (IMM) through PERA2019 performance-based rapid assessment methodology by considering the Design Level and Scenario-Based Earthquake cases. This is the most up-to-date and comprehensive site survey and analysis conducted in Istanbul up to now. In this paper, the characteristics of the building stock in Istanbul based on the conducted site work and the outcomes of the rapid seismic safety assessment efforts are summarized. Then, a discussion on the seismic risk evaluation of the existing residential buildings based on the prioritization of the examined buildings is presented through the results obtained for the Design Level and Scenario-Based Earthquake cases.

How do nonstate organizations carry out their programs in political contexts hostile to civil society activity? This paper examines the case of refugee-supporting organizations in Turkey, which hosts over 3.6 million Syrians under a temporary protection regime. While the Turkish state has taken a central role in refugee reception, nonstate organizations have played a sizeable role in refugee support. Analyzing interviews with key personnel across 23 organizations in Istanbul, the paper finds that organizational capacity and organizational identity together explain variations in CSO-state relations. While high-capacity organizations that adopt a variety of "rights-based" and "needs-based" identities will cooperate with state institutions, lower-capacity organizations use comparable signifiers to justify selective engagement or avoidance of state institutions. The paper argues that analyzing how organizations negotiate their identities can help explain variations in CSO-state relations in restrictive contexts without relying on a priori assumptions about CSO alignment with or opposition to the state.

Due to recent advancements in connected and autonomous vehicles (CAVs), freeway traffic control (FTC) has become a trendy area of research. Combining CAVs and control measures has opened more efficient traffic flow possibilities. However, while there is extensive research on how traffic control and CAVs can enhance traffic flow performance, their safety benefits should be evaluated more comprehensively. It is challenging to distinguish their contributions to traffic flow safety. Studies on the safety of CAVs in traffic flow indicate that traffic flow safety improves with higher market penetration rates (MPR) of CAVs. However, this finding only sometimes aligns with the traffic flow performance effects of CAVs on freeways. This paper introduces a framework for assessing the safety effects of FTC strategies in mixed traffic scenarios involving human-driven vehicles and CAVs. The proposed framework is tested through a microsimulation-based case study in Istanbul, Turkey. The results show that, despite varying MPRs, the safety effects of CAVs and FTC methods do not consistently reduce the number of conflicts in the traffic flow context. [ABSTRACT FROM AUTHOR]

Drought concepts, definition, and classification processes have been in the field of research for decades, and especially the effects of global warming and the resulting climate change have accelerated these researches. The most used procedure for drought categorization has been in the literature under the name of Standardized Precipitation Index (SPI) with the recommendation of the World Meteorological Organization, and many modified versions of it have appeared in the open literature. Although conceptually the SPI is based on the probabilistic standardization index (PSI), some publications use the statistical standardization procedure (SSP) incorrectly. This paper lays out and explains the difference between the two types of standardization. In proper SPI applications, it is necessary to convert a given hydro-meteorological time series probability distribution function (PDF) to a standard (Gaussian) PDF with zero mean and unit standard deviation. SSP cannot accomplish this task, because the original PDF type remains the same after shifting and scaling applications. The comparison of PSI vs. SSP is provided along with their pros and cons. Accurate application of PSI is presented for annual Danube discharge, New Jersey temperature, and Istanbul/Florya precipitation records. [ABSTRACT FROM AUTHOR]

Cytomegalovirus (CMV) can cause serious complications in immunocompromised individuals and fetuses with congenital infections. These can include neurodevelopmental impairments and congenital abnormalities in newborns. This paper emphasizes the importance of concurrently evaluating ultrasonography findings and laboratory parameters in diagnosing congenital CMV infection. To examine the prenatal characteristics of CMV DNA-positive patients, we assessed serum and amniotic fluid from 141 pregnant women aged 19–45 years, each with fetal anomalies. ELISA and PCR tests, conducted in response to these amniocentesis findings, were performed at an average gestational age of 25 weeks. Serological tests revealed that all 141 women were CMV IgG-positive, and 2 (1.41%) had low-avidity CMV IgG, suggesting a recent infection. CMV DNA was detected in 17 (12.05%) amniotic fluid samples using quantitative PCR. Of these, 82% exhibited central nervous system abnormalities. Given that most infections in pregnant women are undetectable and indicators non-specific, diagnosing primary CMV in pregnant women using clinical findings alone is challenging. We contend that serological tests should not be the sole means of diagnosing congenital CMV infection during pregnancy. [ABSTRACT FROM AUTHOR]

In this opinion paper, I trace children's access to play in the urban context against the backdrop of the COVID-19 pandemic. Drawing on the news, civil society organizations' reports and conversations with experts working in Istanbul, Turkey during the last year, I show how children's access to public places in the city gets constrained by urban governance that neglects young people's needs. Examples from the neighborhoods of Istanbul, Turkey, indicate the importance of having in mind the whole community while thinking about bringing play opportunities in public spaces and at the same time raise questions about children's participation in these processes.

While the whole world struggles with the COVID-19 pandemic, there are many different measures taken by countries. In this sense, the distribution of free masks to citizens between the ages of 20–65 in Turkey is one of the important measures taken against to spread of the pandemic. This distribution process is carried out through pharmacies and people can obtain their masks from any pharmacy in their area of residence. However, this situation may cause some pharmacies to be very busy, and thus social distance cannot be maintained and health and safety of the people may be threatened. In this paper, we aim to prioritize pharmacies so that only determined pharmacies in certain regions perform mask distribution process to prevent virus transmission. For this purpose, Esenler district is taken into consideration for a pilot study which is one of the risky regions in terms of virus spread in Istanbul, Turkey. Multi-criteria decision-making approach (MCDM) is used because of the necessity of handling many factors in decision-making process and the contradiction of evaluation factors in the prioritization of pharmacies. In order to best model the uncertainty in the decision process, the MCDM approach is applied in a fuzzy environment. In addition, spherical fuzzy AHP and VIKOR MCDM approaches are used as novel hybrid method in this paper. As a result of spherical fuzzy multi-criteria analysis, the pharmacies that need to provide free mask distribution in the Esenler region have been successfully identified. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to analyze the correlation between the Twitter activity of two airline companies and their stock performance at the Istanbul Stock Exchange (BIST). Design/methodology/approach: Overall, 113,018 tweets were divided into 34,152 semantic and 78,866 share tweets. Semantic tweets are tweets mentioning company's products or services and were labeled manually and with deep learning models. Share tweets were divided into 13,618 relevant and 65,248 irrelevant tweets. Findings: A positive correlation was found between share tweets and stock performance. Semantic tweets did not display a correlation with stock performance. Relevant share tweets displayed as a strong correlation as all share tweets for one company. Also, the manual labeling of 8,000 tweets led to the discovery of many insights related to service provision in the airway industry, management of digital support channels, management of reputation on social media and using Twitter as a customer support platform. Practical implications: Relevant share tweets comprise only 20% of all share tweets for one company and show the same level of correlation with stock performance. This means that the efficiency of business intelligence solutions created to monitor Twitter activity can be improved five times by saving computational power, network bandwidth and data storage. Originality/value: Previous research has analyzed all Twitter activity taken together. By dividing tweets into semantic and share tweets, this paper illustrates that it is, in fact, share tweets that are correlated with stock performance and not semantic tweets. [ABSTRACT FROM AUTHOR]

Biennials are one of the most important stagers of contemporary art practices serving as spaces of reflexivity for artistic production, compressing a glocal sphere, offering a culturally inclusive debate. They play a key role in the global transformation of cultural production in a neoliberal age. Based on empirical data collected from the 15th Istanbul and 10th Liverpool biennials, this paper seeks to interrogate the role they play in the relationship between the cultural production and consumption of the arts. The paper presents an alternative perspective from which we can begin to better understand the cultural impact of neoliberalism. It is suggested, on this basis, that as glocal spaces of culture, biennials can generate culturally inclusive debates and participatory constellations offering a more democratic access to cultural participation. They are in this sense a discursive space and facilitate the opening-up of a critical space in which cultural policy can offer a more sophisticated means of critiquing the impact of neoliberalism on the arts world.

Based mainly on original French archival sources, this paper discusses the conduct and extent of French military and civil activities in Ottoman Istanbul during the Crimean War. Using both qualitative and quantitative indicators, the paper shows how the necessities generated by the war, promoted an unprecedented growth in the French military and civil presence in Istanbul. Through this approach, the paper explains to what degree the war created new market opportunities for various French products and services, a favourable environment for the establishment of French hospitals, and also occasions for cultural encounters between the French and the Ottomans in Istanbul.

This paper addresses issues pertaining to the future of work and sustainability through the lens of a case study of ecological deterioration and how it destroys and creates green jobs in a forest village of Istanbul. As elsewhere in major urban centres of developing countries, the hyper-expansion of city regions due to authoritarian developmentalism fosters the state-led construction sector in Turkey. Growth-driven economic policies continue to have adverse effects on the environment, resulting in deforestation among an array of ecological damage. Based on a qualitative analysis of oral history interviews and observations informed by a larger interdisciplinary research project, we observe resilience in the forest village under scrutiny as certain types of work are abandoned, and new forms are created by adaptation to the ecological and social conditions. The perceptions of changing conditions by locals vary across existing ethnic, gender, and class hierarchies in the local community. Moreover, our findings indicate that the types of work available in the village prior to urban transformation were not all decent or green. In face of ongoing ecological deterioration in a (formerly) forest community, participatory micro-initiatives, and grassroots, utilizing local community projects emerge that nevertheless pursue a green and just transition. We focus on one such initiative, the Community Fungi platform, to demonstrate the possibility of working towards a collective imagination of a green future inspired by past but unforgotten sustainable communal practices, in the context of the forest village under scrutiny in this paper.

Nowadays, logistics is one of the most important tools in disaster relief operations. The logistic planning is essential and a key component in covering the initial needs in the immediate aftermath of any disaster. Planning is both necessary and practical, as it is generally possible to predict the types of disasters that should affect a given location and the needs that such disasters will be likely to cause. Transport planning, reception and distribution of emergency supplies, type and quantity of the resources, the way of procurement and storage of the supplies, the tools of the tracking and means transportation to the stricken area, the specialization of teams participating in the operation and plan of cooperation between these teams, are some vital life-saving coordination roles after natural disasters are connected directly to logistic planning. Turkey is located in one of the most active earthquake and volcanic regions which causes to many major earthquake-prone, in the world with a majority of the population living in these earthquake-prone areas. Earthquakes are one of the major disasters that require emergency logistic planning strategies due to their devastating effects, the large-scale natural disasters could cause major problem on commodities such as food, medicine etc. In this paper, a game theoretical model for emergency logistic planning is developed. To do this a cooperative game model is constructed from a flow problem which occurred after an earthquake in Istanbul. Several solution concepts for maximizing the transferred commodity are given. The paper ends with a conclusion and outlook to future studies. [ABSTRACT FROM AUTHOR]

Timely delivery of products to customers is the great importance for retailers in supply chain management. Vending machines are one of the most effective retail tools for consumers to get the product they want at any time. With the developing technology, retailers tend to establish distribution with vending machines to provide faster service to the consumer. At this point, one of the primary objectives is to make the location selection decisions for these vending machines. The most suitable location selection decision includes the evaluation of each alternative under the specified criteria in a problem where there are multiple alternative locations. The present paper proposes a novel modified Delphi-based spherical fuzzy analytical hierarchy process (SFAHP) integrated spherical fuzzy combinative distance-based assessment (SFCODAS) methodology to the vending machine location selection (VMLS) problem. After determining the main and sub-criteria hierarchically, the Modified Delphi method is used to consolidate the opinions of the experts regarding the criteria and integrate them into the study. The main and sub-criteria weights are provided by the SFAHP method. And the most suitable location is determined by the SFCODAS method by ranking among the alternative locations according to these weighted criteria. The case study of VMLS is presented for a retail firm in Istanbul. Sensitivity analysis is performed to measure the flexibility of the proposed methodology. To validate the applicability of the proposed methodology, comparison analysis is presented with the results of the spherical fuzzy weighted aggregated sum-product assessment (SFWASPAS) method. Finally, the conclusions and future directions are discussed in the study. [ABSTRACT FROM AUTHOR]

In the destinations they visit, tourists wish to see historical structures with that they can establish a connection with. The effects of nostalgic bonds established through experiences can be evaluated only by the determination of individuals' developing intentions and judgments. The main purpose of this study was to identify the relationships between nostalgic emotions, memorable tourism experience, satisfaction, revisit intention, and recommendation intention. In this regard, views of the tourists who visited İstanbul were collected through surveys. A total of 483 surveys were obtained and the data were analyzed using AMOS software. The obtained results showed that strong nostalgic bonds had a positive impact on behavioral intentions such as revisit intention by increasing satisfaction and memorability. The findings of this paper indicated that nostalgic emotions significantly affect memorable tourism experiences. [ABSTRACT FROM AUTHOR]

This article discusses a discovery made by the author involving the wrong manuscript of calligrapher Şekerzâde being printed by the Ottoman Empire. It was initially illegal to sell printed copies of the Qurʾan in Ottoman lands, as cutting letters of the verses was deemed disrespectful. After foreign-printed copies began circulating, the position of the Ottoman government was forced to change. Thereby, the Ministry of Education, led by Ahmed Cevdet Pasha, was commissioned to produce a printed Qurʾan. However, the governmental body accidentally printed a manuscript that Şekerzâde wrote in Istanbul, while indicating it was the Qurʾan he wrote in Medina. Through careful examination, including translations of the inscriptions, this error was noticed for the first time. This paper presents an introduction to Ottoman reverence for the Qurʾan, a history of the printing process, background information of Ahmed Cevdet Pasha, and evidence regarding the mistake made when printing the manuscript.

Considering the age of socio-ecological crises in which we live, the urgency of understanding the complicated relationship between society and nature is apparent. To achieve this, unfolding the urban metabolism of cities through metabolic flows from the perspective of urban political ecology will grow increasingly essential in the future. This paper aims to explore the concept of urban political ecology as a perspective for understanding emergence of a new urban metabolism in İstanbul in the nineteenth century through metabolic flows of water. The context of "metabolic" emphasizes labor as an agent for the very production of nature as urbanized nature through tap water, waste, and sanitation. It shows the transition and the conflict between the labor-intensive urban metabolism and capital-intensive urban metabolism of İstanbul, which started in the nineteenth century. The metabolic flows of water in terms of infrastructure were affected by the first impacts of foreign capital investments and capitalist relations. [ABSTRACT FROM AUTHOR]

The aim of this paper is to expose the significant contribution of colour information to the classification of 3D points from dense aerial image matching. In this study, colour information was used to compensate for the lack of additional information in photogrammetric point clouds with the proposed automatic hierarchical rule-based classification approach. Two point-based classification approaches based on only spatial-based features and combining the use of spatial-based features and colour information were developed in order to classify photogrammetric point cloud data. The hierarchical rules were developed using the selected features for the proposed point-based classification approaches. Detailed parameter analyses for the developed rules were carried out in pilot areas. The photogrammetric point clouds from the Zekeriyakoy test site in Istanbul were automatically classified, and ground, building, and vegetation classes were acquired using only spatial-based features and using both spatial-based features and colour information. The contribution of the colour information was clearly seen in the vegetation points classified as buildings in woodland and urban areas, as well as in the ground points classified as vegetation in urban areas. The performed accuracy analysis of photogrammetric 3D point cloud classification with the combined use of spatial-based features and colour information verified the improvement of overall accuracy from 70 to 78% in comparison to the classification of only spatial-based features.

In this paper, we consider the estimation of a multicomponent stress–strength reliability when stress and strength variables follow unit Bur XII distribution. In estimation procedure, the maximum likelihood and Bayesian methods are used. The maximum likelihood estimator is obtained via iterative methods. The asymptotic confidence interval is constructed using asymptotic properties of the corresponding estimator. In addition, two bootstrap confidence intervals are constructed. Bayesian estimator is obtained using three different approximation methods: Lindley's approximation, Tierney–Kadane approximation and Markov Chain Monte Carlo method. The interval estimation based on Bayesian method is studied. The simulation study is conducted to investigate and compare the performance of the considered methods. Finally, an original data set, general dam occupancy rate of Istanbul, Turkey obtained from Istanbul Statistic Office, is analysed in the concept of multicomponent stress–strength reliability.

The Istanbul Zone (NW Turkey) forms the eastward extension of Avalonia and was subjected to deformation, uplift and erosion for a time period of 40–50 Ma following the collision with the Sakarya Zone during Early to Late Carboniferous. This paper deals with the petrology and age of the volumetrically minor basic and acidic volcanism at the lowermost horizons of Middle Permian continental red beds, which are overlain by Lower Triassic marine sedimentary rocks in the Kocaeli Peninsula. The volcanic activity is represented mainly by amygdaloidal basalt, rhyolite and minor trachydacite. The amygdaloidal basalt was derived from near-primary middle-K calc-alkaline mantle melts with negligible crystal fractionation. On the other hand, the rhyolite and trachydacite compositionally resemble A2-type rhyolites and underwent low-pressure crystal fractionation as indicated by the presence of a significant Eu anomaly. Initial ɛNd values of amygdaloidal basalt range from 0.0 to 1.5 and those of rhyolite-trachydacite are between −0.4 and −3.4. Amygdaloidal basalt and rhyolite-trachydacite are not directly related to each other by crystal fractionation. Amygdaloidal basalt probably represents the product of the near-primary mantle melts from low-degree melting of a spinel peridotitic source, and the rhyolite-trachydacite originated from highly-fractionated products of basic magmas that are slightly more alkaline than amygdaloidal basalt. However, basic and intermediate products of alkaline basic magmas are unknown in this region to date. U-Pb dating of zircons from a rhyolite sample yielded an igneous crystallization age of 261 ± 3 Ma (2σ), suggesting that the date of deposition of the continental red beds goes back to the latest Middle Permian. Based on the transgressive nature of the Permian-Triassic sequence that starts from the Middle Permian continental red beds and grades into Lower Triassic marine deposits, we suggest that the volcanism likely occurred in an extensional setting. This extension was concurrent with the northward subduction of the Palaeo-Tethys beneath the Sakarya and Istanbul zones after the Variscan orogeny. Therefore, the latest Middle to Late Permian volcanism might have occurred during the initial stage of a back-arc extensional setting [ABSTRACT FROM AUTHOR]

Due to the high necessity of medical face masks and face shields during the COVID-19 pandemic, healthcare centers dealing with infected patients have faced serious challenges due to the high consumption rate face masks and face shields. In this regard, the supply chain of healthcare centers should put all of their efforts into avoiding any shortages of masks and shields as these products are considered as primary ways to prevent the spread of the virus. Since, any shortages in these products would lead to irrecoverable and costly consequences in terms of the mortality rate of patients and medical staff. Therefore, healthcare centers should decide on best supplier to supply required products, considering technical, and sustainability measures. Dynamicity and uncertainty of the pandemic are other factors that add up to the complexity of the supplier selection problem. Therefore, this paper develops a novel decision-making approach using Measuring attractiveness through a categorical-based evaluation technique (MACBETH) and a new combinative distance-based assessment method to address the supplier selection problem during the COVID-19 pandemic. Due to high uncertainty, vague and incomplete information for decision-making problems during the COVID-19 pandemic, the developed decision-making approach is implemented under fuzzy rough numbers as a superior uncertainty set of the traditional fuzzy set and rough numbers. Extensive sensitivity analysis tests are performed based on parameters of the decision-making approach, impacts of weight coefficients, and consistency of results in comparison to other MCDM methods. A real-life case study is investigated for a hospital in Istanbul, Turkey to show the applicability of the developed approach. Based on the results of MACBETH method, job creation and occupational health and safety systems are two top criteria. Results of the case study for five suppliers indicate that supplier (A1) is the best supplier with a distance score of 3.308. [ABSTRACT FROM AUTHOR]

This article presents a text on the Ottoman Empire left by Marcantonio Donini – a career secretary with the Venetian diplomatic service, sent three times to Constantinople/Istanbul. After the death of his superior during his second stay in the Ottoman Empire, Donini was entrusted with temporarily heading the mission and with presenting the final mission report (relazione) after his return to Venice (1562). Most probably, he also wrote a much less formal text, composed of three dialogues on the Ottoman reality (signed 1591). Donini's writings attest to well‐developed rhetorical skills, manifested by the clear division of topics between the dialogues and relazione and by the ways used to present alleged Ottoman otherness. Some of the original traits in his writings are also attributable to Marcantonio's individual views and his social position as a secretary. By focusing on Donini and his dialogues, this paper aims to enrich discussion on the scope and content of texts on the Ottoman Empire produced by Venetian diplomats. [ABSTRACT FROM AUTHOR]

City logistics approaches and modeling struggles have a significant role in urban areas in increasing the efficiency of logistics operations and reducing traffic jams and their environmental effects. By developing an effective distribution network for cities, it is possible to compete with the changing world and satisfy flexible customer requirements. In this study, as a real-world case, a city logistics model for Istanbul metropolitan area is designed using multi-objective linear programming that considers the different objectives of the stakeholders in cities by integrating the fuzzy Choquet integral technique in a multi-level distribution network for the automotive spare part industry. This paper makes decisions regarding the amount of product flowing among the echelons, the amount of stock to be kept in the warehouses, and the product delays allowed. While minimizing the transportation cost, holding cost and emission levels during these decisions, the study also aims to maximize the service quality in the warehouses. The model is applied to a logistics network of fifty demand points and thirty time periods which can be considered a middle or large-scale problem. In the model, it is also decided to transport the products with electric or fuel vehicles. In the transport sector, electric vehicles are the key to meet future needs for social, health and other human services. The results are discussed under different scenarios. This research allows the use of such a model in making strategic decisions for the distribution network design in big cities. [ABSTRACT FROM AUTHOR]

Among the aims of Charles VIII's Italian expedition, the reappropriation of the kingdoms of Naples and Jerusalem served as the main purpose for preparing the decisive crusade that would regain Jerusalem to Christianity. However, the connection established by several early modern sources between Charles VIII's claims to the kingdom of Naples and the expedition to the Levant had already been expressed in previous centuries in very similar terms. Also, in the case of Charles I of Anjou in the thirteenth century, the acquisition of the kingdom of Sicily was perceived as a necessary precondition for setting military campaigns aiming at recovering Constantinople and Jerusalem. The same pattern appears also in Benzo of Alba's Ad Heinricum imperatorem (eleventh century), where the pacification of Southern Italy is presented as the first step towards the reunification of the Constantinopolitan empire and the conquest of Jerusalem under the rule of Henry IV. The paper intends to shed light on a geographical pattern that periodically emerges in various iterations of crusading (and pre-crusading) propaganda (very often intertwined with prophetic expectations) which implied a tight interconnection between the recovery of the Holy Land and the unification of the orbis christianus under one universal ruler.

This paper aims to examine the distinct conditions and implications of a multi-level stakeholder analysis for the governance of urban-rural intersections through a case study in Istanbul, adopting an advanced stakeholder analysis from UN-Habitat. Based on a case study of the landscape identity of Istanbul's rural settlements, the study offers multi-level definitions of the 331 stakeholders detected, power-influence matrices, and strategies that may foster balanced multi-level urban-rural governance practices in a major metropolitan area. The findings highlight the multiplicity of levels, sectors, resources, and the actors' differing capacities and interests to influence rural-urban governance decisions as well as their implementation.

This paper examines the stories and works of two Padua-trained Jewish physicians, Joseph Solomon Del Medigo (d.1655) and Tobias Cohen (d.1729) who traveled between major urban centers of the Eastern Mediterranean. In the early modern Mediterranean, Jewish physicians served as the vectors of knowledge between different geographies. The paper will start by rendering the learning and practicing medicine in 16th and 17th century Padua and then move on to the experiences of the abovementioned physicians in the Ottoman Empire with a particular focus on their biographies. The final section of the article will focus on the reasons and consequences of their sojourn in the Ottoman Empire. In addition to scientific quests, the paper argues that Del Medigo and Cohen headed towards the East with religious motives, the realization of which could only be made possible by the career opportunities offered by the Ottomans. This paper will conclude that the stories of Del Medigo and Cohen pose an episode of the coalescent nature of European and Eastern Mediterranean science. [ABSTRACT FROM AUTHOR]

The contemporary city is (re)produced in fragments through numerous typological variations. However, the current practice of spatial planning has yet to suggest effective control mechanisms to steer the piecemeal (trans)formation of cities. This paper argues for parametric modelling as a method of guiding fragmentary developments towards the pluralist production of coherent urban fabrics. Following the parametric definition of the basic morphological codes, the paper discusses the computational capacity of parametric modelling to simulate multiple variations in local fabrics and their consecutive integration within a larger context. The proposed model is tested in the context of Istanbul, Turkey. [ABSTRACT FROM AUTHOR]

This article revisits the concept of (virtual) cruising with the purpose of uncovering an often-disregarded fact in queer theory: that cruising is equally about rejecting as it is about welcoming others/otherness. With the help of two critical conceptual tools, community and immunity, that I borrow from Italian philosopher Roberto Esposito, this paper discusses how a particular Geosocial Networking Application, Hornet, both enables and undermines the emergence of a virtual community in Istanbul, Turkey. While defying heteronormativity, Hornet reproduces violence in the shape of homonormativity, endangering what it claims to offer originally: community. By addressing cruising in relation not only to community but also immunity, this article makes an intervention in queer theory's tendency to reduce cruising to a universal welcoming of otherness. This paper aims to revisit both the communitarian potentials and immunitarian risks of cruising in the light of a rather politicized analysis grounded in the everyday experiences of ordinary people.

This paper analyses the high streets of Istanbul within the context of high street management through four dimensions of location and movement, physical fabric, real estate & land use and exchange, and suggests a comprehensive approach to manage these commercial axes. While analysing the chosen study areas of Istiklal Street, Bagdat Street and Nisantasi District under the given topics, this paper makes use of analyses regarding transportation network, footfall, commercial and non-commercial use, prime rental values, besides a literature review to have an understanding towards the nature of each case study area. The results imply that despite their differences, all three study areas face certain issues that point out the lack of comprehensive strategic approaches to their management. Towards the high streets of Istanbul, this paper proposes a management approach embracing three main goals: (1) to constitute a brand image, (2) to decrease the vulnerability against macroeconomic factors and (3) to maintain vitality and viability of these axes. To overcome the complexities regarding management issues, this paper suggests an organizational and institutional approach, dedicated to considering the interests of all users on high streets.

Iron gall inks have a destructive effect on paper supports due to their acidic and transition metal-containing nature. For the chemical stabilization of paper-based objects, conservation studies include both antioxidant and deacidification treatments. In order to evaluate the effectiveness of the treatments, accelerated ageing experiments are performed and changes during ageing are measured. Historical manuscripts may contain colored papers and since only natural dyes and pigments were available until the development of modern chemistry in the nineteenth century, the palette was limited. Organic dyes mainly consisted of colourants obtained from plants and insects. In this study, colored papers of manuscripts from the fifteenth century which belong to the collections of Millet Library, İstanbul were analyzed via high-performance liquid chromatography. According to the results, model papers were dyed with Rheum ribes L. (rhubarb), and then an iron gall ink, prepared according to a historical recipe, was applied to them. Due to acid and transition metal content, a stabilization treatment including alkali and an antioxidant was applied on a set of samples and after 12 days of accelerated ageing, changes in pH, degree of polymerization, and optical properties of the samples were monitored. A viscometer, a useful tool to monitor the efficiency of a treatment, was employed for the determination of degree of polymerization values. Data obtained from viscometric measurements were used to evaluate the degradation rate constants of the samples. Comparison of rate constants showed that treatment had a beneficial effect.

Global economic restructuring since the 1970s, and the rollback of the welfare state in the Global North has been a major contributor to a reduction in the affordable housing stock. Similarly in the so-called Global South recent economic development has been accompanied by a lack of sustainable affordable housing and housing policies. In this short paper, I aim to analyse important policy papers from the central government of Turkey and local government of Istanbul focusing on the housing policies. I will use content and policy analysis to examine the legal and policy framework in the city of Istanbul and compare this with what is happening on the ground. These policy papers include Istanbul Metropolitan Municipality Strategical Plan (2020–2024), Turkey 11th 5 year Development Plan Housing Politics (2019–2023), Urban Development Strategy (2010–2023) and Istanbul Regional Plan (2014–2023).

City walls have played a significant role in the history of many cities in both Europe and Anatolia in the Middle Ages. Following the development of war technology, the city walls lost their importance as defensive structures, which led to changes in the urban patterns of walled cities. In the case of Istanbul, the city walls began to lose their defensive role after the Ottoman takeover of the city in the fifteenth century. However, the walls have continued to play new roles beyond defense, such as forming the city's physical, legal, and fiscal boundaries. The Ottoman authorities repaired and conserved the city walls in line with their changing roles, values and meaning for the city. Nevertheless, the city walls in Istanbul were damaged by earthquakes, city fires and particularly urban planning practices in the nineteenth century, as was the case in many walled cities. This paper discusses the intertwined history of preservation and demolition of the city walls by analyzing a cost estimate, dated 1894 and located in the Ottoman State Archives, which was prepared by the modernizing administration of the Ottoman State for the repairs of the Istanbul Land Walls.

This paper emphasizes the significance of social infrastructure in understanding urban inequality. In addition to its economic opportunities, social infrastructure is one of the distinguishing characteristics of metropolitan areas. In cities of the 21st century, social infrastructure is not equally accessible to all residences. For the development and sustainability of urban life, social infrastructure is fundamental. In terms of establishing a sense of belonging and integration to contemporary urban life, social infrastructure is highly crucial especially for refugees and rural migrants who migrate to the periphery of big cities. By evaluating the findings of this study conducted in Esenler District, we aim to contribute to research dealing with urban inequalities in Istanbul from the perspective of social infrastructure. To fill a gap in the literature, the social infrastructure of the Esenler District, which consists of rural-to-urban migration, refugee flow, and the working class in Istanbul's periphery, was analyzed by comparing it to other districts. The database created from various data sources and satellite images is presented with thematic maps. According to the findings, there is a significant divide between the central and peripheral districts of Istanbul in terms of social infrastructure. This inequality manifests itself in four ways: education, health, recreation, and fuel for housing. First, there are serious problems, such as the limited number of kindergartens, the high-class size in primary schools, and the poor quality of high schools in front of Esenler, which has a low education level. Second, there are only six healthcare centers in Esenler, where health services are inadequate compared to the central districts. Third, the green space cannot meet the recreational needs of the dense population in the district where unplanned and intensive construction has left no free space. Due to limited purchasing power, natural gas usage in Esenler is fairly low compared to central districts, despite the dense population. On the basis of these indicators, it has been concluded that the Esenler District, lacks the essential social infrastructure services necessary to maintain the city's health. Therefore, strengthening the social infrastructure on the urban periphery is a primary concern for developing a better understanding of urban inequalities, preventing problems, and making livable urban environments.

Foucault’s pendulum is one of the most important scientific achievements of the French physicist Léon Foucault. The performance of the experiment in 1851 was the first tangible proof of the Earth’s rotation. The relative technical simplicity and beauty of the experiment led to many repetitions of it, the manufacture of related pendulums by scientific instrument manufacturers, and the permanent or temporary installation of such pendulums in educational institutions for teaching as well as aesthetic reasons. The Phanar Greek Orthodox College in İstanbul is the oldest operating school of the city’s Greek community. After many moves during the first four centuries of its operation, the College found a permanent home in an impressive privately owned building in Fener in 1881. The building hosts a rich collection of scientific instruments, acquired mainly in the last quarter of the 19th century by French manufacturers and at the beginning of the 20th by Germans and Austrians. In 1912 special changes were made to the building to house a Foucault pendulum which was manufactured by the German company Max Kohl. This paper presents the history of this device, which is one of the first (perhaps the first) used in the Ottoman Empire. [ABSTRACT FROM AUTHOR]

How should we understand the relationship between artistic practice and religious devotion? This paper answers that question through a close engagement with the archive of the artist, teacher, doctor, and writer Ahmet Süheyl Ünver (b. 1898–d. 1986). Working from notebooks and archival files produced about Eyüp, Istanbul's most important Muslim district, I offer the concept of 'conjunctions of Islam' to develop two linked arguments. First, Ünver's work challenges essentialist invocations of 'Turkish' or 'Islamic' art. Instead, his work shows us how these terms are historically and geographically specific, embedded within networks of people, places, objects, and histories. Second, Ünver also shows us how definitions of Muslim identity trace geographies other than the territorial nation. Indebted to discussions of relational place-making and topology, my use of conjunction helps us see the making of an urban Muslim self in a new way. In doing so, this article extends recent cultural geographic discussions about skill and creativity, provides a new perspective on the geographies of Islam, and enriches our ability to explain how complex forms of the past are articulated in contemporary Turkey.

While research on geographies of creativity have proliferated in the last few years, there has been scant attention to religious cultural and artistic practices, particularly in the context of the Middle East. This research seeks to address such gap with a focus on the Islamic and traditional visual arts scene which has flourished in Istanbul in the past decade and a half along with the rise of political Islam in Turkey. Rendered obsolete through the Western-oriented and secular cultural politics since the early republican era, art forms such as Arabic calligraphy (hat), miniature (minyatür), and illumination (tezhip) have now found currency as 'authentically Turkish and Islamic' in an art scene that emerged alongside Islamist politics. This paper examines the trajectory of Islamic and traditional visual arts through the lens of cultural and creative industries starting from the cultural politics of Islamic urban governance through the 1990s and 2000s, and to the emergence of an Islamist-nationalist authoritarianism in the past decade. In doing so, it aims to situate Islamic and traditional visual arts on the map in studies on geographies of creativity, particularly in the Middle Eastern and Islamic context, where limited attention has been paid to cultural and artistic practices. With ethnographic reflections from the field, it highlights the internal dynamics of an art scene and the potential it bears in unsettling the core concepts of Turkish Islamic nationalism from within.

The paper deals with the reception of the Qur'an in two late fifteenth-century pilgrimage texts to the Holy Land, the Itineraria of the Bruges patricians Anselmo and Giovanni Adorno (1470–1471) and the Mantuan judge Antonio da Crema (1486–1489). The two experiences are placed in the 'twilight' of medieval peregrinatio, after the failure of the Crusade projects that followed the fall of Constantinople (1453). Both texts present a dual profile: on the one hand, they retain the traditional character and form, whereby the text is a veridical certification and memory of a devout act, the return to the places of Christ and the Scriptures. On the other hand, they graft onto the record of direct experience information derived from several written sources. In this interweaving of empirical data and literary filter lies the effort to bring rational order to the signs of religious Otherness, perceived in the Qur'an. [ABSTRACT FROM AUTHOR]

This paper foregrounds the state–corporate alliance in real estate development in Istanbul since the early 2000s. Employing a geo-coded sample of 294 private housing development projects built since the early 1980s and in-depth interviews with the private development companies, the paper focuses on how the construction industry and the massive commodification of urban land produced a new state–space nexus. The underlying question here is the nascent shape of urban political-economy, the trends of housing construction, the cycles of boom and bust and the mechanisms of capital accumulation concerning the state's centralising control over space. In this sample, a few critical aspects of the production of concrete space became apparent. Seven findings are discussed. First, the developers of Istanbul followed the clientelistic patterns in the urban built environment. The second aspect is that the state is the sole supply-side actor that determines Istanbul's built environment. The third point in this analysis of urban development initiated by the private sector is focused on the fact that the real estate speculation is state-led. The fourth and fifth points are related to the Turkish real estate developers' inability to procure financing for the duration of the construction process. The sixth factor in the evaluation of the private real estate sector in Istanbul is the geographical and class dispersal of active development projects. The seventh factor in understanding those real estate developers is their novel approach to marketing and advertisement and the way they employ architecture as an extension of public relations.

Multi-Criteria Decision Making (MCDM) methods help researchers in solving many problems in terms of numerical analysis. However, MCDM methods have not been very popular in the health sector. In this study, five ones of Turkey's most intense and highly populated cities were selected and the risk of the spread of Covid-19 disease was evaluated on the basis of seven criteria. The PROMETHEE and the ELECTRE methods were conducted to rank the cities in terms of the spread of Covid-19. The PROMETHEE method correctly ranked the most risky city as Istanbul, but ELECTRE ranked Istanbul the second most risky. The results of the methods are compared with real data. PROMETHEE gave more convenient results than ELECTRE. Also, this paper offers a new field of study to the literature. [ABSTRACT FROM AUTHOR]

Digital technologies, which have made significant progress in the last two decades, have paved the way for the emergence of many new-generation devices, platforms and applications. The increase in the use of these technologies has transformed many activities in daily life and significantly changed the business world. The concept of digital transformation, which has become a popular motto for many companies today, has improved the interaction between companies and consumers and changed how companies do business, making the transformation necessary. Digital transformation in businesses can be partial (such as establishing new departments or marketing channels) or major (such as changing the entire business model). In any case, digital transformation is a necessity of the current age. Human capital is vital in increasing the firm performance of companies and gaining a competitive advantage against their competitors. Today, one factor that can improve employees' task performance in digital economies is digital competencies. Therefore, having a certain level of digital literacy among employees is crucial for companies to achieve adequate performance in digitalization and beyond. From this perspective, this research aims to determine the effect of employees' digital literacy on their task performance and firm performance. Investigation of this topic in the paper is carried out in the following logical sequence: First of all, the research presents the conceptual framework for digital literacy, task performance, and firm performance. The results of studies in the literature are presented, and the hypothesis development process is based on the research results. The subsequent section provides information about the study's methodology and findings. Finally, the research concludes with the results and discussion section. Within the scope of the study, data were collected from 222 white-collar employees in Istanbul through online questionnaires. A convenience sampling technique was used to determine the sample. SPSS 25 and SPSS Process 2.13 package programs were used to analyse the data. The research results show a medium-level relationship between digital literacy and task performance, a mediumlevel relationship between digital literacy and firm performance, and a high and positive relationship between firm performance and task performance. According to the mediation analysis results, employees' digital literacy positively affects task performance and firm performance. In addition, it has been determined that task performance plays a mediating role in the effect of employees' digital literacy on firm performance. It appears that company managers should prioritize the focus of the «Reskilling Revolution Initiative», which emphasizes the transformation of employees' skills to attain sustainable competitive advantage and enable digital transformation.

The paper aims to measure, using the VAIC model, the impact of intellectual capital and its elements on the financial performance and sustainable growth of Turkish ICT companies listed on the Istanbul Stock Exchange (ISE). Panel data regression was used to analyse 31 Turkish ICT companies' activity for 2019-2022. To measure the relationships between financial performance, sustainable growth and its determinants, sixteen functional models were developed, the formation of which was based on the following types of used dependent variables - Return on Assets, Return on Equity, Return on Sales, Sustainable Growth Rate. Ten independent variables were used, such as VAIC, Modified VAIC, Capital Employed Efficiency, Human Capital Efficiency, Structural Capital Efficiency, Research and Development Capital Efficiency, Relational Capital Efficiency, Leverage, Size, and Dummy Variable for Subbranch. The findings expand the understanding of the importance of intellectual capital management in generating enterprise value and providing sustainable advantages by high-tech companies in the context of forming a knowledge-based economy. The regression analysis of the impact of VAIC and its structural components on Turkish ICT companies' financial performance and sustainable growth showed rather contradictory results. The most significant effects on the financial performance of Turkish ICT companies and sustainable development are Return on Assets - VAIC, Modified VAIC, Human Capital Efficiency, Research and Development Capital Efficiency, Leverage, Dummy Variable for Subbranch; Return on Equity - Human Capital Efficiency, Leverage; Return on Sales - Human Capital Efficiency, Leverage, Structural Capital Efficiency, Size; and Sustainable Growth Rate - Research and Development Capital Efficiency, Capital Employed Efficiency, Leverage. The expediency of increasing investments in the development of experience and professional skills of employees of Turkish ICT companies, as well as strengthening their innovative activities, which will ensure the growth of their profitability in the short term, have been substantiated.

Outside of the Global North, where agri-food systems have not yet consolidated into a 'funnel shape,' what makes an urban provisioning actor 'alternative' is not always clear. In this paper, I use members' own definitions, emphases, and arguments to differentiate 'alternative' networks from other provisioning actors. Using data from semi-structured interviews, I show that while community-building and an affiliation with the food movement (broadly defined) are the most critical features identified by people who participate in these networks, more informal, ad hoc, familial or village networks that are utilized as a response to urban food insecurity are excluded. While such exclusions may not be unique, in this case, they reflect more fundamental divisions regarding what 'alternative' implies and how to challenge the throttling hold of conventional provisioning agents on the contemporary agri-food system.

This paper investigates the effects of soil–structure interaction and site amplification on the seismic response of one of the towers of the Theodosian walls of Constantinople during the Kocaeli earthquake in 1999, that largely damaged it. The interacting system is first analysed in the frequency domain by the well-known replacement oscillator model, turning out that the effect of soil–structure interaction could be relevant. The complete system is then examined by the direct approach considering non linearity of the behaviour of both the structure and the soil. The failure mechanism detected from where stress and plasticization concentrate into the masonry panels is consistent with the out-of-plane mechanism of one of the tower façades triggered by the reference earthquake. The focus was then set on the effectiveness of some retrofitting interventions, including the lateral disconnection of the embedded sides of the tower from the surrounding soil, the soil treatment by grouted columns and the classical technique for masonry rehabilitation. Even though the latter choice is the most common one, retrofitting interventions concentrated into the soil could be effective as well. Their use should be properly considered when the scope of the intervention is the preservation of cultural heritage. [ABSTRACT FROM AUTHOR]

This paper examines eight marble samples from the architectural elements and liturgical furniture of the ecclesiastical complex of Santa Giustina in Padova (Italy), founded by the Rufus Venantius Opilio before AD 524. The provenance determination of the marbles was carried out by means of a multi-analytical approach combining mineralogical–petrographic investigations, performed by microscopic observations of thin sections, and the measurement of the ratios of stable carbon and oxygen isotopes. The results obtained were compared with up-to-date petrographic and isotopic databases (Antonelli and Lazzarini 2015), and they showed that the analyzed marbles come from the quarries of the island of Proconnesus in Asia Minor, modern Marmara Adası (Turkey). Archaeometric evidence, together with the stylistic and functional analysis of the pieces, suggests the direct importation of a complete set of sculptures, shipped at different stages of workmanship from the workshops of Constantinople and expressly ordered by a single patron, who can be identified as Opilio, founder of the basilica of Santa Giustina and praetorian prefect at the court of King Theodoric.
