Cappadocia in Turkey is an important region with emphasis on ethnic and historic structures and geological features. Because of volcanic eruptions, ash flow materials deposited at different levels. These different colored ignimbrite levels have a wide range of geomechanical properties. In the region, the Kızılkaya ignimbrite covers a very large area and is frequently used as building dimension stone in for the restoration of old historical buildings such as churches, caravansaries and mosques as well as new buildings. It contains tuffaceous matrix with some minerals and rock fragments. The rock has variable character. In this study, the relationship between petrographic and physico-mechanical properties of the Kızılkaya ignimbrite was investigated. Rate of change between uniaxial compressive strength and the other index properties of the rock was statistically examined utilizing multiple regression analysis (MRA) and Artificial Neural Network (ANN) methods. The study has shown that uniaxial compressive strength (UCS) of the ignimbrite can be successfully estimated by the use of dry unit weight, effective porosity, sonic velocity, and grain matrix ratio (GMR) parameters. A new UCS prediction equation is proposed in this paper for the ignimbrite with variable character. Since properties of the ignimbrite at different distances from the eruption area changes significantly, the approach presented in this study can be considered for the ignimbrites especially covering a large area with different welding degrees and grains.

ADAPTIVE reuse of buildings , *HERITAGE tourism , *TOURISM , *GENTRIFICATION - Abstract
Since the last quarter of the twentieth century, increased tourism in traditional settlements have led to the adaptive reuse of built vernacular heritage to serve the tourism industry. The adaptive reuse of historic buildings is considered a conservation strategy and an alternative to new constructions in historic environments. Nevertheless, the adaptive reuse of built vernacular heritage and its socio-spatial impacts have not yet been sufficiently investigated. To fill the gap, this paper, focuses on Cappadocia, Turkey, where adaptive reuse of individual vernacular houses has recently paved the way for the transformation of an entire neighbourhood, the historic neighbourhood of Kayakapı, into a 'holiday village.' This study argues that traditional settlements and communities in Cappadocia have been subjected to 'gentrification' and so-called 'Disneyfication.' Such historic environments are facing controversial physical interventions, detached from local communities and devoted to a single function, namely tourism, becoming 'stereotypical and depersonalised.' The study further argues that the current situation is incompatible with international heritage and conservation policies. Correspondingly, to reveal the potential conflicts, the recent revitalisation project of the historic neighbourhood of Kayakapı in Cappadocia is examined as a case study. [ABSTRACT FROM AUTHOR]

Cappadocia Region (World Heritage Site registered by UNESCO) carries thousands of rock-cut structures, masonries and fairy chimneys, which have been used in every aspect of daily life. Damages occurred during their working life, and restoration with inappropriate materials are threatened these structures. Moreover, an enormous amount of waste material is excavated throughout the carving process, passing approximately 10 million cubic meters per annum, creating pollution in the region, and not being used efficiently. This study aims to use Cappadocia waste earth (CWE) in the grout for consolidation and strengthening rock-cut structures, masonries and fairy chimneys located in Cappadocia region. The utilization of this waste earth in the grout prevents the destruction of these valuable structures and provides a solution to a critical environmental problem. The experiments were conducted employing by 30%, 40%, and 50 wt% of Cappadocia waste earth with natural hydraulic lime in the existence of chemical admixtures. The influence of ambient temperatures (5°C, 20°C, and 40°C) and time-dependent behavior on the rheological performance of grouts were investigated. The findings revealed that dosages of Cappadocia waste earth, different environmental temperatures, and constant shearing (time-dependent) have critical roles in determining the optimum requirements for injection.

Rock-cut structures of Cappadocia, which are enlisted as natural and cultural World Heritage Sites by UNESCO, have particular acoustics due to the specific tuff stone belonging to the region. This study, for the first time, discusses the indoor sound fields of the Cappadocia over five selected spots (one church and four residential halls) from Middle Byzantine sites of Hallaç, Açıksaray and Avanos with an aim of providing evidence regarding the spatial features and culture of the people inhabited these spaces. Acoustical data is collected during in-situ field tests. Acoustic parameters (EDT, T20, T30, C80, CD50, and STI) are obtained for the spaces under study. The rock-cut church is found to be the most reverberant among all the spaces and the most suitable for liturgical practices. The other four spaces are observed as comparatively more favorable for speech-related activities. The study also compares the sound absorption performance of Cappadocian tuff stone to those present in other natural caves and rock-cut structures investigated throughout the world in few prominent studies.

Purpose: The main purpose of the study is to determine the mediating role of trait anxiety in the relationship between hotel managers' perceptions of digital competence in the Cappadocia Region and their perceptions of job insecurity. Design/methodology/approach: In this study, which is based on quantitative research, a cross-sectional design was used. The seven-item digital competence scale, four-item job insecurity scale and 20-item trait anxiety scale were used to measure the level of digital competence, job insecurity and trait anxiety of hotel managers. The convenience sampling method was used in the research, and 337 questionnaires were completed by senior and junior managers who agreed to participate in the research. To test the mediating role of trait anxiety, Andrew F. Hayes' views on the contemporary approach were taken as a basis. Findings: The analysis results showed that digital competence had the opposite effect on job insecurity. Similarly, digital competence had the opposite effect on the level of trait anxiety. The level of trait anxiety affected the perception of job insecurity in a linear direction. As a result of the bootstrapping test, it was found that the indirect effect of trait anxiety on the relationship between digital competence and job insecurity was significant. Research limitations/implications: The study was unable to collect data from hotels that were closed during the COVID-19 pandemic due to restrictions. Therefore, one of the limitations of the study was that it did not reach the entire population. Another limitation of the study was that the questionnaires were addressed to hotel managers in the Cappadocia Region. Practical implications: Hotel managers' digital skills are considered to contribute to the tourism industry by organizing and determining business strategies, work processes and employee skills. In addition, when hiring hotel managers, it is essential to ensure that they have certain skills such as compatibility with the digital age, openness to innovation and the ability to adapt the employees working in their team to the age, which helps to improve the competitiveness of the hotel industry with the world and ensure the continuity of this situation. Originality/value: The research addressed the variables of digital competence, job insecurity and trait anxiety and collected data from hotel managers in the Cappadocia Region using a survey technique. There were few studies that addressed these variables, and the mediating effect of trait anxiety was revealed based on the contemporary approach. [ABSTRACT FROM AUTHOR]

The Greek Orthodox Community was uprooted from Cappadocia with the signing of the Convention of the Exchange of Populations between Turkey and Greece at Lausanne on 30 January 1923. Until then Potámia had been one of the prosperous villages of the area, thanks to financial contributions of Potámian migrants in foreign lands. In the late nineteenth and early twentieth centuries the village had stone houses, a new church, and a school. The villagers had neighborly relations with the Turks of surrounding villages, with a degree of competition at the communal level which was reflected in their narratives, myths, and songs. These narratives are revealing of their senses and perceptions of their neighbors in the last decades of their existence in their homeland, and they are meaningful in allowing researchers to detect the cohabitation practices of two religious communities at the time.

This study investigates the changes in paleoenvironmental conditions in the northern branches of the Neo-Tethys by employing geochemical proxies and shell data of larger benthic foraminifera (LBF) located in central Cappadocia. Three measured stratigraphic sections are studied from the Altipinar Formation (Boztepe Member), which is dated as middle Eocene. Three genera and five specieswere recorded as a result of the paleontological analyses, namely, Alveolina sp., Assilina exponens, Nummulites aturicus, Nummulites maximus and Nummulites perforatus. Composed of clayey sandy limestones, the Boztepe Member is represented by SBZ (Shallow Benthic Zones) 16-17 (late Lutetian/early Bartonian). In the Cappadocia region, a warming event was characterized by a temperature increase of 3°C to 4.5°C, and the warming started after 41.0 Ma (younger than the Lutetian /Bartonian boundary). The peak warming occurred around 40.0 Ma (early Bartonian). This period corresponds to the Middle Eocene Climatic Optimum (MECO), which was a significant global warming event. The findings of this study are confirmed by numerous studies that the global warming event occurred in the middle Eocene (between 41.8 and 39.7 Ma.). Additionally, while paleoenvironmental changes had no effect on the shell shape of Assilina exponens, they had a significant effect on the shell shape of Nummulites perforatus. The diameter/thickness ratio of benthic foraminifera tends to be smaller in shallowconditions than in deep conditions. Thiswas observed as their shell shapes becamemore spherical.

Rockfalls are one of the most dangerous natural events in hilly terrains, and they substantially threaten residential areas and transport corridors in these environments. This study is aimed to analyze the risk of rockfall from a slope to nearby houses in a historical settlement with past rockfall histories. It contains numerous applications to study rockfall danger from different points of view (e.g., kinematics, numerical stability analysis, risk assessment, 2D trajectory). The rockfall kinematics revealed the statistics for different structurally controlled failure modes among the surveyed slope discontinuities, especially wedge type and block toppling were the most significant ones. Finite element analysis showed that the slope was stable under the natural condition with a safety factor of 2.19. The rockfall risk rating system calculated a medium risk for the houses downstream. Based on the field measurements, a possible rockfall profile was determined and located as an input in the 2D rockfall trajectory program. The rigid-body impact model runs utilized various shapes and sizes of blocks to simulate the rockfall events realistically. According to the 2D trajectory model results, there was no rockfall danger for the investigated downslope houses. The study showed the importance of using different analysis techniques to solve rockfall risk in protected areas based on scientific and rational approaches. [ABSTRACT FROM AUTHOR]

12. Gendering sustainability's contradictions: between change and continuity.

ETHNOLOGY research ,TOURISM ,SUSTAINABILITY ,FOOD security - Abstract
Understanding sustainability to be multifaceted and inherently contradictory, this article draws on long-term ethnographic research in the Cappadocia region of central Turkey to explore the gendered manifestations of various tourism-related 'sustainability fluxes'. In particular, I consider the ways in which both change and continuity are legitimized through sustainability and tourism and so manifest in contradictory ways to shape women's lives and practices. I identify four key sustainability fluxes as especially relevant in this tourism context. Firstly, women's empowerment through tourism work and increased gender equality through social and educational reform are discussed in relation to their enabling and legitimizing of change. Secondly, and reacting against these changes, are fears over sustainable food security plus nostalgic concerns over cultural sustainability. These latter sustainability fluxes engage with tourism and heritagization processes to revalue certain gendered food-production practices, and thereby legitimize continuity tying women's lives and practices to a logic of sameness. Contributing a feminist anthropology approach and guided by poststructuralist feminist thought, the article develops nuanced understanding not only of how these contradictory legitmizations "do things" in shaping women's lives and practices, but also of where ambivalences lay between acceptance and resistance to both change and continuity.

Voluminous moderate- to high-magnesian [Mg# = molar Mg/(Mg + Fe
2+ ) = 44–64] andesitic and dacitic rocks with high silica (mostly 61–66 wt%) adakitic affinity (Y = 13–22, Yb = 1.3–2.1, Sr/Y = 18–44, La/Yb = 10–25) and common mafic magmatic enclaves (MMEs) are first reported in the Keçiboyduran stratovolcano (KSV) from the Cappadocia volcanic province (CVP), Central Anatolia, Turkey. We present comprehensive whole-rock geochemistry and Sr–Nd–Pb isotope data, mineral chemical compositions and40 Ar–39 Ar ages for KSV samples. Based on the volcanostratigraphy and40 Ar–39 Ar dating results, two successive eruption ages of 2.2–1.6 Ma (stage I: amphibole-rich) and 1.6–1.2 Ma (stage II: pyroxene-rich) were established for the KSV, corresponding to the Gelasian and Calabrian stages of Early Pleistocene, respectively. Textural and geochemical evidence indicates that the KSV magnesian andesites–dacites are products of a hybrid magma formed by mixing between mantle-derived mafic and crust-derived felsic magmas with further fractionation and minor contamination during magma storage and ascent. Our new data, combined with previous geological and geophysical results suggest that parental magnesian mafic melts of the KSV rocks originated from a heterogenous mantle source generated through the metasomatism of mantle wedge material by subducted sediment-derived melts, and then partially melted through asthenospheric upwelling in response to slab break-off. The mafic magma underplated the overlying lower crust, resulting in its partial melting to generate crustal felsic magma. Both magmas mixed at lower crustal levels creating MME-rich hybrid magmas. Subsequently, the hybrid magmas were emplaced at different depths of the crust (c. 4–11 and 11–15 km for the stage I and II, respectively), where they crystallized at moderate temperatures (c. 1180–840 °C) and under relatively high oxygen fugacity (LogƒO2 = − 11.4 to − 9.2), water-rich (H2 Omelt = 5.6–3.6 wt%) and polybaric (~ 1.2 to 5.1 kbars) conditions, and underwent fractionation of primarily amphibole ± pyroxene causing adakitic affinity. We propose a new petrogenetic model for the early Quaternary magnesian/adakitic andesites/dacites of the CVP in a post-subduction tectonic setting. Our results provide robust evidence for slab break-off of the eastern Cyprus oceanic lithosphere and put further constraints on the tectonic evolution of the eastern Mediterranean collision zone during the Early Quaternary.

This study investigates the indoor acoustical characteristics of a Middle Byzantine masonry church in Cappadocia. The Bell Church is in partial ruins; therefore, archival data and the church's remains are used for its acoustical reconstruction. The study aims to formulate a methodology for a realistic simulation of the church by testing the applicability of different approaches, including field and laboratory tests. By conducting qualitative and quantitative material tests, different tuff stone samples are examined from the region. Impedance tube tests are performed on the samples from Göreme and Ürgüp to document their sound absorption performances. Previous field tests on two sites in Cappadocia are also used to compare the sound absorption performance of tuff stones, supported by acoustical simulations. The texture, physical and chemical characteristics of the stones together with the measured sound absorption coefficient values are comparatively evaluated for selecting the most suitable material to be applied in the Bell Church simulations. The church was constructed in phases and underwent architectural modifications and additions over time. The indoor acoustical environment of the church is analyzed over objective acoustical parameters of EDT, T30, C50, C80, D50, and STI for its different phases with different architectural features and functional patterns.
