This article builds on the insights of feminist theory and employs the conceptual vocabulary of the social movement framing perspective in maintaining gender as a main parameter of framing processes. Drawing on ethnographic research on local community struggles against hydropower plants in the Eastern Black Sea Region of Turkey, this article maintains the centrality of gender to framing processes. It analyzes the gendered difference between men's macro-framings and women's cultural and socio-ecological framings, which is rooted in their differing relationships with their immediate environment, as well as with the state and its institutions. The article maintains that the framings of women, which represent the immediacy of the environment, are more effective in gaining public support and shaping movement outcomes. In this sense, constructing gender as an important determinant of "frame variation" is essential not only to reveal women's frames that are largely silenced through and within the mechanisms of social movement organization, but also to stress their centrality in shaping repertoires of contention, public reception and movement outcomes.}, language = {en} } @article{Yaka2020, author = {Yaka, {\"O}zge}, title = {Justice as relationality}, series = {Die Erde : journal of the Geographical Society of Berlin ; Zeitschrift der Gesellschaft f{\"u}r Erdkunde zu Berlin}, volume = {151}, journal = {Die Erde : journal of the Geographical Society of Berlin ; Zeitschrift der Gesellschaft f{\"u}r Erdkunde zu Berlin}, number = {2-3}, publisher = {Gesellschaft f{\"u}r Erdkunde}, address = {Berlin}, issn = {0013-9998}, doi = {10.12854/erde-2020-481}, pages = {167 -- 180}, year = {2020}, abstract = {By introducing a notion of socio-ecological justice, this article aims to deepen the relationship between environment and justice, which has already been firmly established by environmental justice movements and scholarship.

Each participant read three short case scenarios (vignettes) and completed items pertaining to the female victim and male perpetrator. The vignettes were systematically varied with regard to the type of crime that was committed (rape or robbery), the perpetrator's coercive strategy (physical force or exploiting the victim's alcohol-induced defenselessness), and the victim-perpetrator relationship prior to the incident (stranger, acquaintance, or ex-partner). Furthermore, participant gender and acceptance of rape myths (beliefs that justify or trivialize sexual violence) were taken into account. One half of the participants completed the rape myth acceptance (RMA) scales first and then received the vignettes, while the other half were given the vignettes first and then completed the RMA scales. As expected, more blame was attributed to victims of rape than to victims of robbery. Conversely, perpetrators of rape were blamed less than perpetrators of robbery. The more participants endorsed rape myths, the more blame was attributed to the victim and the less blame was attributed to the perpetrators. Increasing levels of RMA were associated with an increase in victim blame (VB) in both rape and robbery cases, but the increase in rape VB was significantly more pronounced than in robbery VB. Increasing RMA was associated with an attenuation of perpetrator blame (PB) that was more pronounced for rape than for robbery cases, but the difference was not significant. As expected, victims of rape were blamed more when the perpetrator exploited their defenselessness due to alcohol intoxication than when they were overpowered by physical force. Contrary to the hypothesis, this was also true for robbery victims. Rape victims who knew their attacker (ex-partner or acquaintance) were blamed more than victims who were assaulted by strangers. Contrary to the hypothesis, robbery victims who were assaulted by an ex-partner were blamed more than acquaintance or stranger robbery victims. As predicted, the closer the relationship between victim and perpetrator, the less blame was attributed to perpetrators of rape while this factor had no effect on PB in robbery cases. Men compared to women attributed more blame to the victims and less blame to the perpetrators. As expected, these gender differences in blame attributions were partially mediated by gender differences in RMA: After RMA was taken into account, the gender differences disappeared nearly completely for VB and were significantly reduced in PB. The order of presentation of the vignettes and the RMA measures was systematically varied to test the causal influence of RMA on rape blame attributions. The hypothesis that RMA causes VB and PB in rape cases (as opposed to the other way around or both are caused by a third variable) was not supported. Possible reasons for this failed manipulation and its implications for the mediation model are discussed. With regard to blame attribution in rape cases, the present results match what was expected from previous studies which were mainly conducted in "Western" countries like the United States, the United Kingdom, or Germany. The present results support the notion that the victim-perpetrator relationship and the victim's alcohol consumption are cross-culturally stable factors for blame attribution in rape cases. It was expected that blame attribution in robbery cases would be unaffected by the perpetrator's coercive strategy and the victim-perpetrator relationship, but the results were inconsistent. One unexpected effect is particularly noteworthy: When the perpetrator used physical force, more blame was attributed to rape than to robbery victims, but intoxicated victims were blamed more and almost equally so for both types of crime. Perpetrators who exploited drunk victims were blamed less in both rape and robbery cases. These results contradict German results collected with the German version of the same instruments (Bieneck \& Krah{\´e}, 2011). Turkey is a Muslim country and alcohol is surrounded by a certain taboo. Possibly, the results reflect a cultural difference in that intoxicated victims are generally blamed more for their victimization and this factor is not limited to rape cases.}, language = {en} } @misc{SchusterKrahe2017, author = {Schuster, Isabell and Krah{\´e}, Barbara}, title = {The prevalence of sexual aggression in Turkey: A systematic review}, series = {Aggression and violent behavior : a review journa}, volume = {37}, journal = {Aggression and violent behavior : a review journa}, publisher = {Elsevier}, address = {Oxford}, issn = {1359-1789}, doi = {10.1016/j.avb.2017.05.003}, pages = {102 -- 114}, year = {2017}, abstract = {Although sexual aggression is recognized as a serious problem worldwide, evidence on the prevalence and impact of sexual aggression is based predominantly on studies from Western countries with a Christian or non-religious majority.

The first aim of this research project was to systematically review the available evidence provided by past studies on this topic within each country. The second aim was to empirically study the prevalence of experiencing and engaging in sexual aggression since the age of consent among college students in Chile and Turkey. The third aim was to conduct cross-cultural analyses examining pathways to victimization and perpetration based on a two-wave longitudinal design. Methods: This research adopted a gender-inclusive approach by considering men and women in both victim and perpetrator roles. For the systematic reviews, multiple-stage literature searches were performed, and based on a predefined set of eligibility criteria, 28 studies in Chile and 56 studies in Turkey were identified for inclusion. A two-wave longitudinal study was conducted to examine the prevalence and predictors of sexual aggression among male and female college students in Chile and Turkey. Self-reports of victimization and perpetration were assessed with a Chilean Spanish or Turkish version of the Sexual Aggression and Victimization Scale. Two path models were conceptualized in which participants' risky sexual scripts for consensual sex, risky sexual behavior, sexual self-esteem, sexual assertiveness, and religiosity were assessed at T1 and used as predictors of sexual aggression victimization and perpetration at T2 in the following 12 months, mediated through past victimization or perpetration, respectively. The models differed in that sexual assertiveness was expected to serve different functions for victimization (refusal assertiveness negatively linked to victimization) and perpetration (initiation assertiveness positively linked to perpetration). Results: Both systematic reviews revealed that victimization was addressed by all included studies, but data on perpetration was severely limited. A great heterogeneity not only in victimization rates but also in predictors was found, which may be attributed to a lack of conceptual and methodological consistency across studies. The empirical analysis of the prevalence of sexual aggression in Chile revealed a victimization rate of 51.9\% for women and 48.0\% for men, and a perpetration rate of 26.8\% for men and 16.5\% for women. In the Turkish original data, victimization was reported by 77.6\% of women and 65.5\% of men, whereas, again, lower rates were found for perpetration, with 28.9\% of men and 14.2\% of women reporting at least one incident. The cross-cultural analyses showed, as expected, that risky sexual scripts informed risky sexual behavior, and thereby indirectly increased the likelihood of victimization and perpetration at T2 in both samples. More risky sexual scripts were also linked to lower levels of refusal assertiveness in both samples, indirectly increasing the vulnerability to victimization at T2. High sexual self-esteem decreased the probability of victimization at T2 through higher refusal assertiveness as well as through less risky sexual behavior also in both samples, whereas it increased the odds of perpetration at T2 via higher initiation assertiveness in the Turkish sample only. Furthermore, high religiosity decreased the odds of perpetration and victimization at T2 through less risky sexual scripts and less risky sexual behavior in both samples. It reduced the vulnerability to victimization through less risky sexual scripts and higher refusal assertiveness in the Chilean sample only. In the Turkish sample only, it increased the odds of perpetration and victimization through lower sexual self-esteem. Conclusions: The findings showed that sexual aggression is a widespread problem in both Chile and Turkey, contributing cross-cultural evidence to the international knowledge base and indicating the clear need for implementing policy measures and prevention strategies in each country.

Accordingly, a methodology based on experiences from developing countries was proposed by the United Nations Office for Disaster Risk Reduction (UNDRR) to estimate direct economic losses on the macro-scale. Since Turkey also signed the SFDRR, we aimed to adapt, validate and apply the loss estimation model proposed by the UNDRR in Turkey for the first time. To do so, the well-documented flood event in Mersin of 2016 was used to calibrate the damage ratios for the agricultural, commercial and residential sectors, as well as educational facilities. Case studies between 2015 and 2020 with documented losses were further used to validate the model. Finally, model applications provided initial loss estimates for floods occurred recently in Turkey. Despite the limited event documentation for each sector, the calibrated model yielded good results when compared to documented losses. Thus, by implementing the UNDRR method, this study provides an approach to estimate the direct economic losses in Turkey on the macro-scale, which can be used to fill gaps in event databases, support the coordination of financial aid after flood events and facilitate monitoring of the progress toward and achievement of Global Target C of the Sendai Framework for Disaster Risk Reduction 2015-2030.}, language = {en} } @phdthesis{Koc2021, author = {Ko{\c{c}}, Gamze}, title = {A comprehensive analysis of severe flood events in Turkey}, doi = {10.25932/publishup-51785}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-517853}, school = {Universit{\"a}t Potsdam}, pages = {209}, year = {2021}, abstract = {Over the past decades, natural hazards, many of which are aggravated by climate change and reveal an increasing trend in frequency and intensity, have caused significant human and economic losses and pose a considerable obstacle to sustainable development. Hence, dedicated action toward disaster risk reduction is needed to understand the underlying drivers and create efficient risk mitigation plans. Such action is requested by the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR), a global agreement launched in 2015 that establishes stating priorities for action, e.g. an improved understanding of disaster risk. Turkey is one of the SFDRR contracting countries and has been severely affected by many natural hazards, in particular earthquakes and floods. However, disproportionately little is known about flood hazards and risks in Turkey. Therefore, this thesis aims to carry out a comprehensive analysis of flood hazards for the first time in Turkey from triggering drivers to impacts. It is intended to contribute to a better understanding of flood risks, improvements of flood risk mitigation and the facilitated monitoring of progress and achievements while implementing the SFDRR. In order to investigate the occurrence and severity of flooding in comparison to other natural hazards in Turkey and provide an overview of the temporal and spatial distribution of flood losses, the Turkey Disaster Database (TABB) was examined for the years 1960-2014. The TABB database was reviewed through comparison with the Emergency Events Database (EM-DAT), the Dartmouth Flood Observatory database, the scientific literature and news archives. In addition, data on the most severe flood events between 1960 and 2014 were retrieved. These served as a basis for analyzing triggering mechanisms (i.e. atmospheric circulation and precipitation amounts) and aggravating pathways (i.e. topographic features, catchment size, land use types and soil properties). For this, a new approach was developed and the events were classified using hierarchical cluster analyses to identify the main influencing factor per event and provide additional information about the dominant flood pathways for severe floods. The main idea of the study was to start with the event impacts based on a bottom-up approach and identify the causes that created damaging events, instead of applying a model chain with long-term series as input and searching for potentially impacting events as model outcomes. However, within the frequency analysis of the flood-triggering circulation pattern types, it was discovered that events in terms of heavy precipitation were not included in the list of most severe floods, i.e. their impacts were not recorded in national and international loss databases but were mentioned in news archives and reported by the Turkish State Meteorological Service. This finding challenges bottom-up modelling approaches and underlines the urgent need for consistent event and loss documentation. Therefore, as a next step, the aim was to enhance the flood loss documentation by calibrating, validating and applying the United Nations Office for Disaster Risk Reduction (UNDRR) loss estimation method for the recent severe flood events (2015-2020). This provided, a consistent flood loss estimation model for Turkey, allowing governments to estimate losses as quickly as possible after events, e.g. to better coordinate financial aid. This thesis reveals that, after earthquakes, floods have the second most destructive effects in Turkey in terms of human and economic impacts, with over 800 fatalities and US\$ 885.7 million in economic losses between 1960 and 2020, and that more attention should be paid on the national scale. The clustering results of the dominant flood-producing mechanisms (e.g. circulation pattern types, extreme rainfall, sudden snowmelt) present crucial information regarding the source and pathway identification, which can be used as base information for hazard identification in the preliminary risk assessment process. The implementation of the UNDRR loss estimation model shows that the model with country-specific parameters, calibrated damage ratios and sufficient event documentation (i.e. physically damaged units) can be recommended in order to provide first estimates of the magnitude of direct economic losses, even shortly after events have occurred, since it performed well when estimates were compared to documented losses. The presented results can contribute to improving the national disaster loss database in Turkey and thus enable a better monitoring of the national progress and achievements with regard to the targets stated by the SFDRR. In addition, the outcomes can be used to better characterize and classify flood events. Information on the main underlying factors and aggravating flood pathways further supports the selection of suitable risk reduction policies. All input variables used in this thesis were obtained from publicly available data. The results are openly accessible and can be used for further research. As an overall conclusion, it can be stated that consistent loss data collection and better event documentation should gain more attention for a reliable monitoring of the implementation of the SFDRR. Better event documentation should be established according to a globally accepted standard for disaster classification and loss estimation in Turkey. Ultimately, this enables stakeholders to create better risk mitigation actions based on clear hazard definitions, flood event classification and consistent loss estimations.}, language = {en} } @article{KocThieken2017, author = {Koc, Gamze and Thieken, Annegret}, title = {The relevance of flood hazards and impacts in Turkey}, series = {Natural hazards : journal of the International Society for the Prevention and Mitigation of Natural Hazards}, volume = {91}, journal = {Natural hazards : journal of the International Society for the Prevention and Mitigation of Natural Hazards}, number = {1}, publisher = {Springer}, address = {New York}, issn = {0921-030X}, doi = {10.1007/s11069-017-3134-6}, pages = {375 -- 408}, year = {2017}, abstract = {Turkey has been severely affected by many natural hazards, in particular earthquakes and floods.

Therefore, this study aims to investigate the severity of flooding in comparison with other natural hazards in Turkey and to analyse the flood patterns by providing an overview of the temporal and spatial distribution of flood losses. These will act as a metric for the societal and economic impacts of flood hazards in Turkey. For this purpose, Turkey Disaster Database (TABB) was used for the years 1960-2014. As input for more detailed event analyses, the most severe flood events in Turkey for the same time interval will also be retrieved. Sufficiency of the TABB database to achieve the main aim of the study in terms of data quality and accuracy was also discussed. The TABB database was analysed and reviewed through comparison, mainly with the Emergency Events Database (EM-DAT), the Global Active Archive of Large Flood Events-Dartmouth Flood Observatory database, news archives and the scientific literature, with a focus on listing the most severe flood event. The comparative review of these data sources reveals big mismatches in the flood data, i.e. the reported number of events, number of affected people and economic loss all differ dramatically. Owing to the fact that the TABB is the only disaster loss database for Turkey, it is important to explore the reasons for the mismatches between TABB and the other sources with regard to aspects of accuracy and data quality. Therefore, biases and fallacies in the TABB loss data are also discussed. The comparative TABB database analyses show that large mismatches between global and national databases can occur. Current global and national databases for monitoring losses from national hazards suffer from a number of limitations, which in turn could lead to misinterpretations of the loss data.

This paper presents an outcome that could be used for future urban planning and flood risk prevention studies to understand the flood mechanisms in different regions of Turkey.}, language = {en} } @article{CandanKoralayAkaletal.2011, author = {Candan, Osman and Koralay, O.

Metaconglomerates occur as laterally discontinuous channel-fill bodies close the base of the metaquartzarenite directly above the basement. The pebbles in the metaconglomerates consist mainly of different types of tourmaline-rich leucocratic granitoids, tourmalinite and schist in a sandy matrix. Petrographic features, geochemical compositions and zircon radiometric ages (549.6 +/- 3.7-552.3 +/- 3.1 Ma) of the diagnostic clasts of the metaconglomerates (e.g. leucocratic granitoids and tourmalinites) show excellent agreement with their in situ equivalents (549.0 +/- 5.4 Ma) occurring in the Pan-African basement as stocks and veins. The correlation between clasts in the metaconglomerates and granitoids of the basement suggests that the primary contact between the basement and cover series is a regional unconformity (supra-Pan-African Unconformity) representing deep erosion of the Pan-African basement followed by the deposition of the cover series. Hence the usage of 'core-cover' terminology in the Menderes Massif is valid. Consequently, these new data preclude the views that the granitic precursors of the leucocratic orthogneisses are Tertiary intrusions.}, language = {en} } @article{CandanKoralayTopuzetal.2016, author = {Candan, O. and Koralay, O.

These well-preserved rocks were locally converted into eclogitic metagabbros and garnet amphibolites along the contacts or shear zones. Both bulk-rock composition and compositions of igneous clinopyroxenes suggest continental tholeiitic affinity. U-Pb dating of igneous zircons from gabbroic rocks yielded a mean age of 563 +/- 1 Ma (2 sigma), indicating emplacement during the latest Neoproterozoic (Ediacaran). On the other hand, rims of zircons from eclogitic metagabbro gave 535 +/- 3 Ma (2 sigma) (early Cambrian), in addition to 558 +/- 3 Ma (2 sigma) obtained from the igneous core of zircons. These ages are interpreted as the time of high-P metamorphism and crystallization age of gabbroic protolith, respectively. Given the estimated paleogeographic position of the Anatolide-Tauride Block during the late Neoproterozoic and early Cambrian, this orogenic event can be spatially and temporally related to the northward continuity of 600-500 Ma orogenic event (Malagasy/Kuunga orogeny) extending from western margin of India, Madagascar, via Arabia up to northern margin of Gondwana beneath thick Phanerozoic cover series in Arabian Peninsula. Therefore, the high-P evolution of the basement of the Menderes Massif and associated basic intrusions can be interpreted to mark the latest stages of consumption of the basin/oceanic branches and final amalgamation of the Gondwana during the late Neoproterozoic-early Cambrian around the Arabian region.

These processes have created multiple co-genetic fluvial and marine terrace sequences that serve as excellent strain markers to assess the ongoing evolution of the Pontide orogenic wedge and the growth of the northern margin of the Central Anatolian Plateau. We used high-resolution topographic data, OSL ages, and published information on past sea levels to analyse the spatiotemporal evolution of these terraces; we derived a regional uplift model for the northward advancing orogenic wedge that supports the notion of laterally variable uplift rates along the flanks of the Pontides. The best-fit uplift model defines a constant long-term uplift rate of 0.28 +/- 0.07 m/ka for the last 545 ka. This model explains the evolution of the terrace sequence in light of active tectonic processes and superposed cycles of climate-controlled sea-level change. Our new data reveal regional uplift characteristics that are comparable to the inner sectors of the Central Pontides; accordingly, the rate of uplift diminishes with increasing distance from the main strand of the restraining bend of the North Anatolian Fault Zone (NAFZ). This spatial relationship between the regional impact of the restraining bend of the NAFZ and uplift of the Pontide wedge thus suggests a strong link between the activity of the NAFZ, deformation and uplift in the Pontide orogenic wedge, and the sustained lateral growth of the Central Anatolian Plateau flank.

The Afyon Zone contains widespread metavolcanic rocks, which are dominated by rhyolite, dacite, and trachyandesite. They form a distinct volcanic succession, which is separated from the underlying Silurian-Lower Carboniferous metacarbonates and meta-siliciclastics by a regional unconformity. Trachyandesitic metavolcanics are made up of massive lava flows, pyroclastics and epiclastics, less frequently, domes and dikes, which were developed on a deeply eroded subaerial landmass. U/Pb and Pb/Pb zircon geochronology yielded Lower Triassic (similar to 250 Ma) ages, which are interpreted as extrusion age of trachyandesitic volcanics. Based on the stratigraphic, geochronological, and geochemical data, we suggest that these Lower Triassic magmatic rocks represent an extensional tectonic setting on the northern active margin of the Gondwana, which led to the development of the northern branch of the Neo-Tethys.}, language = {en} }
