description: The analysis of the recent charged-current neutrino-nucleus scattering cross sections measured by the ArgoNeuT Collaboration requires relativistic theoretical descriptions also accounting for the role of final-state interactions. In this work, we evaluate differential neutrino-nucleus cross sections with the relativistic Green's function model, where final-state interactions are described in the inclusive scattering consistently with the exclusive scattering using a complex optical potential. The sensitivity to the parameterization adopted for the phenomenological optical potential is discussed. The predictions of the relativistic Green's function model are compared with the results of different descriptions of final-state interactions.

description: To make an all-electric aircraft possible, both high power densities and efficiencies are needed. However, particularly high demands are also placed on the thermal management system. Often, the electric motor and cooling system are considered without co-optimization. Particularly in the case of electric motors with conductors directly cooled by a liquid, there is great potential for optimization, since the temperature-dependent Joule losses determine the largest part of the losses. This publication shows the main influencing parameters for the electric motor and cooling system: coolant speed and winding temperature. In addition, the influence of the cooling system control during a flight mission is demonstrated and its potential in mass reduction is quantified. It could be shown that with a low utilized electric motor the maximum winding temperature of 130 (Formula presented.) C is beneficial, the cooling system should work in almost all operation points in its sized operation and the mass of the heat exchanger and pump is negligible compared to the mass of the electric motor and energy storage.

description: Cryogels from noble metal NPs have proven to be highly efficient catalysts due to their high specific surface area which increases the mass transfer channels and catalytic active sites. By using metal oxides as co-catalysts, the costs of the material can be significantly reduced, while the catalytic activity can remain the same or even improve due to synergetic effects. In this work, we synthesize different cryogel thin films supported on modified ITO substrates from Pt, Pd nanoparticles (NPs), and mixtures of these noble metals with γ-Fe2O3 NPs in a very low concentration (1 wt% of the noble metal). Structural and elemental analysis of the samples are performed, along with the measurement and analysis of their catalytic activity. The electrocatalytic activity of the cryogels towards ethanol oxidation reaction (EOR) in alkaline media was evaluated by means of cyclic voltammetry. By mixing γ-Fe2O3 NPs with Pt or Pd NPs in the cryogel structure, we observe increased tolerance against poisonous surface intermediates produced during the EOR. Moreover, we observe an increase in the catalytic activity towards EOR in the case of the 1 wt% Pd/γ-Fe2O3 cryogel, making them promising materials for the development of direct ethanol fuel cells.
Seeing patterns in noise: Gigaparsec-scale `structures' that do not violate homogeneity

description: Clowes et al. (2013) have recently reported the discovery of a Large Quasar Group (LQG), dubbed the Huge-LQG, at redshift z~1.3 in the DR7 quasar catalogue of the Sloan Digital Sky Survey. On the basis of its characteristic size ~500 Mpc and longest dimension >1 Gpc, it is claimed that this structure is incompatible with large-scale homogeneity and the cosmological principle. If true, this would represent a serious challenge to the standard cosmological model. However, the homogeneity scale is an average property which is not necessarily affected by the discovery of a single large structure. I clarify this point and provide the first fractal dimension analysis of the DR7 quasar catalogue to demonstrate that it is in fact homogeneous above scales of at most 130 Mpc/h, which is much less than the upper limit for ΛCDM. In addition, I show that the algorithm used to identify the Huge-LQG regularly finds even larger clusters of points, extending over Gpc scales, in explicitly homogeneous simulations of a Poisson point process with the same density as the quasar catalogue. This provides a simple null test to be applied to any cluster thus found in a real catalogue, and suggests that the interpretation of LQGs as `structures' is misleading.

description: Executive Summary

 This deliverable aims at describing the user orientation towards EMPHASIS pilot services. This document provides a summary of the results of the Global Plant Phenotyping Survey launched in November 2020 and concluded in March 2021. GPPS was performed in collaboration with the International Plant Phenotyping Network (IPPN).
 The plant phenotyping community was interrogated both on general issues and on a set of specific questions to further evaluate EMPHASIS pilot services, which were developed on the basis of the user demand identified by the past two surveys (2017 and 2018). Data collected are a picture of the recent trends in plant phenotyping in Europe and can serve as valuable tools for further analyses to help shaping and supporting the future of plant phenotyping.
 The database originated from the survey has been delivered to the phenotyping community: https://zenodo.org/badge/DOI/10.5281/zenodo.4723409.svg

description: Voluntary approaches have become a popular in the U.S. to enhance the efficacy and scope of existing regulations and to reduce emissions in sectors or for pollutants where formal environmental regulation is lacking. In this paper, we examine the effectiveness of a particular EPA voluntary program for the metal finishing industry, the Strategic Goals Program (SGP). The Strategic Goals Program is a good candidate for evaluation because it had a credible regulatory threat at the time the program was implemented, we can measure both baseline emissions and progress towards explicit environmental goals, and we have data for participants and non-participants. We look at the decision to participate in the SGP and also try to determine what effect, if any, this program has had on the pollution profile of facilities. In addition, we examine whether the voluntary program had any discernible impact on toxicity-weighted emissions. Finally, we explore the possibility that we have a bimodal distribution in the sample caused by the different motivations of facilities to join a voluntary program. A number of factors influence a firm’s decision to participate in SGP, including trade group membership. However, we do not find robust evidence that SGP participation has had a significant impact on emission reductions. This result continues to hold when we adjust emissions to account for toxicity. Our measure of the threat of regulation is correlated with emission reductions for both participants and non-participants.

Weighted Aspects for Sentiment Analysis

Publisher: name: Purdue University Graduate School

Subjects: Natural language processing

description: When people write a review about a business, they write and rate it based on their personal experience of the business. Sentiment analysis is a natural language processing technique that determines the sentiment of text, including reviews. However, unlike computers, the personal experience of humans emphasizes their preferences and observations that they deem important while ignoring other components that may not be as important to them personally. Traditional sentiment analysis does not consider such preferences. To utilize these human preferences in sentiment analysis, this paper explores various methods of weighting aspects in an attempt to improve sentiment analysis accuracy. Two types of methods are considered. The first method applies human preference by assigning weights to aspects in calculating overall sentiment analysis. The second method uses the results of the first method to improve the accuracy of traditional supervised sentiment analysis. The results show that the methods have high accuracy when people have strong opinions, but the weights of the aspects do not significantly improve the accuracy.
Steady state conductance in a double quantum dot array: The nonequilibrium equation-of-motion Green function approach

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We study steady state transport through a double quantum dot array using the equation-of-motion approach to the nonequilibrium Green functions formalism. This popular technique relies on uncontrolled approximations to obtain a closure for a hierarchy of equations, however its accuracy is questioned. We focus on 4 different closures, 2 of which were previously proposed in the context of the single quantum dot system (Anderson impurity model) and were extended to the double quantum dot array, and develop 2 new closures. Results for the differential conductance are compared to those attained by a master equation approach known to be accurate for weak system-leads couplings and high temperatures. While all 4 closures provide an accurate description of the Coulomb blockade and other transport properties in the single quantum dot case, they differ in the case of the double quantum dot array, where only one of the developed closures provides satisfactory results.This is rationalized by comparing the poles of the Green functions to the exact many-particle energy differences for the isolate system. Our analysis provides means to extend the equation-of-motion technique to more elaborate models of large bridge systems with strong electronic interactions.

description: Executive Summary Plant phenotyping was established as a tool to address the bottleneck in basic plant science to understand the plant –environment interaction and translate this knowledge into application. Plant phenotyping has largely benefited over the last 10-15 years from technological development in non-invasive sensor technology paired with automation and engineering leading to substantial investment and development of high throughput plant phenotyping installations. The access to the installations is demanded by the user community, which was demonstrated by the infrastructure projects EPPN and EPPN2020 leading to the development of the Research infrastructure EMPHASIS which is supposed to provide a coordinated effort to integrate the plant phenotyping activities in Europe and explore the full potential of plant phenotyping. Plant phenotyping will most likely further benefit from technological developments and by integrated effort which includes shared use of the facilities deliver towards systemic solution of grand challenges related to sustainable agriculture. Further development will also include the use of plant phenotyping as a tool another disciplines leading to further diversification of solutions needed to address different crops, environmental scenarios, agroecology aspects etc. Commitment of policy makers and funders is essential to develop a long term strategy.

Gender Discrimination

Women Mentor

description: Medical Sciences is the branch of science concerned with the study of the diagnosis, treatment, and prevention of disease. Some of the hurdles that women face in medical science which was once unanimously seen as an ‘old white boys club’ are similar cross-culturally but more often are uniquely influenced by cultural and societal norms that vary from country to country. The aim of our study is to elucidate the challenges women face once completing their undergraduate medical education and identify the difficulties that affect them during their specialty and their experiences of discrimination and hurdles when moving up the career ladder. We also wish to find out how their domestic lives influence their careers by asking about the attitudes of their parental and betrothed family. Frequently cited reasons in western countries by women who are discouraged from pursuing surgery as a career are a lack of female role models and a hostile culture with a lack of work-life flexibility. In addition to this women may not feel comfortable pursuing surgical subspecialty due to the fallacious axiom of the ‘surgical personality’. Whilst there definitely is a surgical personality its characteristics are not gender-specific and may be found in both men and women however having the skills and traits suited to a particular profession may not let one prosper due to social circumstances and external factors. The lack of well-conducted research on such an issue in low and middle-income countries makes this study both exciting and necessary to provide baseline data and give an accurate picture of the issues we face which is the first step to be done if we are to solve them.

description: In this paper we develop a method to describe perturbatively the entanglement entropy in a simple impurity model, the interacting resonant level model (IRLM), at low energy (i.e. in the strong coupling regime). We use integrability results or the Kondo model to describe the infra-red fixed point, conformal field theory techniques initially developped by Cardy and Calabrese and a quantization scheme that allows one to compute exactly Renyi entropies at arbitrary order in $1/T_B$ in principle, even when the system size or the temperature is finite. We show that those universal quantities at arbitrary interaction parameter in the strong coupling regime are very well approximated by the same quantities in the free fermion system in the case of attractive Coulomb interaction, whereas a strong dependence on the interaction appears in the case of repulsive interaction.

Using the equipartition of kinetic and magnetic energies, we estimate the steady-state magnetic field of the protostar to be of the order of kilo-gauss, which is in good agreement with observations.

description: Let G be a group acting cocompactly without inversion on a tree X, with all vertex and edge stabilizers isomorphic to the same free abelian group Z^n. We prove that G has the Haagerup Property if and only if G is weakly amenable, and we give a necessary and sufficient condition for this to happen. In particular, denoting by d the rank of the fundamental group of the graph X modded out by G, we deduce that G has the Haagerup Property if either d=0, d=1, or n=1. In these three cases, we show that the L^p-compression rate of G is 1, and that its equivariant L^p-compression rate is max{1/p,1/2} (provided G is non-amenable). We also discuss quasi-isometric embeddings of G into a product of finitely many regular trivalent trees.

description: We study from first principles the transport properties of Al/AlOx/Al tunnel junctions. On this basis, we analyze the reliability of two analytical models for the conductance, namely the trapezoid potential barrier model and a tight-binding model. Our findings show that (i) the interface width used in the models is determined by the electronic density profile, and it is shorter than the width one expects from the atomic arrangements; (ii) the effective mass}, found to be about on third of the free electron mass, can be determined from the oxide band-structure calculations, and (iii) the barrier height is given by one fourth of the bandgap in the oxide, which explains the apparently small values found for these junctions experimentally.

description: In 2000 Professor Dr Helmut van Thiel, the eminent scholar and editor of the Homeric epics, hosted on his homepage at Universität Köln freely available PDF files containing plain text versions of his editions of the Iliad and Odyssey. The PDF files went under the titles 'iliaspur', 'odysspur', and a combined version in one file, 'homerpur'. Sadly, at some point, the webpage went offline. These files were uniquely valuable precisely because they contain just the plain text, with no modern punctuation or diacritics. The letters were in a font designed to resemble the Greek alphabet, but the characters used were actually Beta Code. In addition, each line began with an annotation giving the reference for each line: 'A1' up to 'W804' for the Iliad, and 'a1' up to 'w548' for the Odyssey. These features made the files ideally suited for searching the text for metrical formulas and other repeated phrases. It would be regrettable if this data were lost to time. The attached version is the result of exporting the text from the PDF files. The file is in plain text format, with UTF-8 character encoding and Windows (CR LF) line breaks.

description: The Kunapajala (filthy fluid) or Kunapambu (fermented filth) is one of the traditional organic liquid formulations used since ages. Kunapajala was derived from Sanskrit words 'Kunapa' (smelling like dead body, corpse) and 'Jala' (water). Earliest record of this organic formulation was found possibly in two documents i.e. 'Vrikshayurveda' (Surapala 1,000 AD) and 'Lokopakara' (Chavundaraya, 1,025 AD). Unfortunately, the preparation, use and beneficial role of Kunapajala was forgotten till publication of English translated version of Vrikshayurveda. Valmiki Sreenivasa Ayangarya was the first one who experimented with Kunapajala and documented the beneficial role of herbal Kunapajala on mango and coconut. He also observed enhancement in growth of chilli plant after application of herbal Kunapajala prepared from naturally fallen sour mango and soapnut. Later, in Arunachal Pradesh, he prepared different types of Kunapajala like Indsafari (through aerobic fermentation of safari fish in cow urine), Mushika Kunapa (through aerobic fermentation of body parts of rats in cow urine) and Kukkuta Kunapa (through aerobic fermentation of chicken flesh in cow urine) to apply in different crops like tea bushes, kiwi fruit garden etc. and obtained positive results through their growth promoting and pesticide properties (Biswas and Das, 2023).

description: Cloud computing platform gives people the opportunity for sharing resources, services and information among the people of the whole world. In private cloud system, information is shared among the persons who are in that cloud. Presently, different types of internet based systems are running in Cloud Computing environment. E-commerce is one of them. Present models are not secured enough for executing e-transactions easily, especially in cloud platform. Again, most of the time, clients fail to distinguish between the good online business companies and the bad one, which discourages clients and companies to migrate in cloud. In this paper, we have proposed a newer e-commerce architecture depends on encryption based secured and fuzzy logic based certain trust model which will be helpful to solve present e-commerce problems. We had discussed about the whole working procedure of the model in this paper. Finally, at the end of this paper, we have discussed some experimental results about our proposed model which will help to show the validity of our model.

description: The quasi-persistent neutron star low-mass X-ray binary MXB 1659-29 went into quiescence in 2001, and we have followed its quiescent X-ray evolution since. Observations over the first 4 years showed a rapid drop in flux and temperature of the neutron star atmosphere, interpreted as cooling of the neutron star crust which had been heated during the 2.5 year outburst. However, observations taken approximately 1400 and 2400 days into quiescence were consistent with each other, suggesting the crust had reached thermal equilibrium with the core. Here we present a new Chandra observation of MXB 1659-29 taken 11 years into quiescence and 4 years since the last Chandra observation. This new observation shows an unexpected factor of ~3 drop in count rate and change in spectral shape since the last observation, which cannot be explained simply by continued cooling. Two possible scenarios are that either the neutron star temperature has remained unchanged and there has been an increase in the column density, or, alternatively the neutron star temperature has dropped precipitously and the spectrum is now dominated by a power-law component. The first scenario may be possible given that MXB 1659-29 is a near edge-on system, and an increase in column density could be due to build-up of material in, and a thickening of, a truncated accretion disk during quiescence. But, a large change in disk height may not be plausible if standard accretion disk theory holds during quiescence. Alternatively, the disk may be precessing, leading to a higher column density during this latest observation.

description: Although women often outperform men in school and college, they still face higher unemployment rates and lower wages when employed. Are prospective workers aware of these inequalities, or do they expect to enter a gender-neutral workplace? This paper investigates college students’ expectations and the effect of information provision about gender gaps in academic performance and early labor market outcomes on the two sides of the labor market. Our lab experiment comprises a questionnaire to elicit students’ beliefs about academic performance and labor market inequalities, a demand-side game, and a supply-side game. In the demand-side game, subjects act as employers and are asked to hire three candidates and assign them to tasks that differ in complexity and profitability. In the supply-side game, we elicit individual willingness to compete. Information provision takes the form of feedback on the elicited beliefs. Our treatments vary the timing of the feedback: subjects in the feedback treatment received feedback before facing the other two games, while subjects in the priming and the control treatments only received feedback at the end of the experiment. First, our findings indicate that participants are largely unaware of gender gaps. Second, while information provision doesn't substantially alter employers’ hiring decisions, it increases the likelihood of assigning women to challenging tasks. Third, while feedback enhances willingness to compete among job market candidates, it does not significantly alter the gender gap in competitiveness. Overall, our experiment suggests potential positive effects of information provision on women’s labor market outcomes.

description: AAA+ ATPases are ubiquitous hexameric unfoldases acting in cellular protein quality control. In complex with proteases, they form protein degradation machinery (the proteasome) in both archaea and eukaryotes. Here, we use solution-state NMR spectroscopy to determine the symmetry properties of the archaeal PAN AAA+ unfoldase and gain insights into its functional mechanism. PAN consists of three folded domains: the coiled-coil (CC), OB and ATPase domains. We find that full-length PAN assembles into a hexamer with C2 symmetry, and that this symmetry extends over the CC, OB and ATPase domains. The NMR data, collected in the absence of substrate, are incompatible with the spiral staircase structure observed in electron-microscopy studies of archaeal PAN in the presence of substrate and in electron-microscopy studies of eukaryotic unfoldases both in the presence and in the absence of substrate. Based on the C2 symmetry revealed by NMR spectroscopy in solution, we propose that archaeal ATPases are flexible enzymes, which can adopt distinct conformations in different conditions. This study reaffirms the importance of studying dynamic systems in solution.

description: We present a one-loop calculation of the oblique S and T parameters within strongly-coupled models of electroweak symmetry breaking with a light Higgs-like boson. We use a general effective Lagrangian, implementing the chiral symmetry breaking SU(2)_L x SU(2)_R -> SU(2)_{L+R} with Goldstones, gauge bosons, the Higgs-like scalar and one multiplet of vector and axial-vector massive resonance states. Using a dispersive representation and imposing a proper ultraviolet behaviour, we obtain S and T at the next-to-leading order in terms of a few resonance parameters. The experimentally allowed range forces the vector and axial-vector states to be heavy, with masses above the TeV scale, and suggests that the Higgs-like scalar should have a WW coupling close to the Standard Model one. Our conclusions are generic and apply to more specific scenarios such as the minimal SO(5)/SO(4) composite Higgs model.

description: The eigenmodes and the vibrational density of states of the ground state configuration of graphene clusters are calculated using atomistic simulations. The modified Brenner potential is used to describe the carbon-carbon interaction and carbon-hydrogen interaction in case of H-passivated edges. For a given configuration of the C-atoms the eigenvectors and eigenfrequencies of the normal modes are obtained after diagonalisation of the dynamical matrix whose elements are the second derivative of the potential energy. The compressional and shear properties are obtained from the divergence and rotation of the velocity field. For symmetric and defective clusters with pentagon arrangement on the edge, the highest frequency modes are shear modes. The specific heat of the clusters is also calculated within the harmonic approximation and the convergence to the result for bulk graphene is investigated.

description: Inspired by the insightful article arXiv:1210.7587, we revisit the Nualart-Peccati-criterion arXiv:math/0503598 (now known as the Fourth Moment Theorem) from the point of view of spectral theory of general Markov diffusion generators. We are not only able to drastically simplify all of its previous proofs, but also to provide new settings of diffusive generators (Laguerre, Jacobi) where such a criterion holds. Convergence towards gamma and beta distributions under moment conditions is also discussed.

description: Architected materials exhibit extraordinary properties in comparison with conventional materials and structures, resulting in additional functionality and efficiency by engineering the geometry in harmony with the base material. Buckling-induced architected materials (BIAMs) are a class of architected materials that exhibit a significant potential to absorb and dissipate energy owing to their local instabilities. Previous studies have shown a trade-off between energy dissipation and geometrical recoverability in metallic BIAM, which limits their use in applications that require both of these features. This study, for the first time, presents 4D printing of buckling-induced architected iron-based shape memory alloys (BIA Fe-SMAs) using laser powder bed fusion (LPBF). The results show that 4D printing of BIA Fe-SMAs can offer both energy dissipation and geometrical recoverability (i.e., recentring). The study was conducted on two different alloy compositions of Fe-17Mn-5Si-10Cr-4Ni. Quasi-static cyclic tests were performed on the two BIA Fe-SMAs, and the samples were subsequently heated to 200 °C to activate the shape memory effect (SME) of the base material. The samples could recover the residual deformations accumulated during the cyclic load owing to the SME of the base material, which led to shape-recovery ratios of 96.8 and 98.7% for the studied BIA Fe-SMAs. The results of this study demonstrate that 4D printing of BIA Fe-SMAs can yield an enhanced multi-functional behavior by combining the material's inherent functional behavior with the functionalities of the architected structure. Notably, BIA Fe-SMA samples could reconfigure their initial shape without damage after densification, which sets them apart from conventional crushable lattices.

description: Misfolding and aggregation of transthyretin (TTR) cause several amyloid diseases. Besides being an amyloidogenic protein, TTR has an affinity for bicyclic small-molecule ligands in its thyroxine (T4) binding site. One class of TTR ligands are trans-stilbenes. The trans-stilbene scaffold is also widely applied for amyloid fibril-specific ligands used as fluorescence probes and as positron emission tomography tracers for amyloid detection and diagnosis of amyloidosis. We have shown that native tetrameric TTR binds to amyloid ligands based on the trans-stilbene scaffold providing a platform for the determination of high-resolution structures of these important molecules bound to protein. In this study, we provide spectroscopic evidence of binding and X-ray crystallographic structure data on tetrameric TTR complex with the fluorescent salicylic acid-based pyrene amyloid ligand (Py1SA), an analogue of the Congo red analogue X-34. The ambiguous electron density from the X-ray diffraction, however, did not permit Py1SA placement with enough confidence likely due to partial ligand occupancy. Instead, the preferred orientation of the Py1SA ligand in the binding pocket was determined by molecular dynamics and umbrella sampling approaches. We find a distinct preference for the binding modes with the salicylic acid group pointing into the pocket and the pyrene moiety outward to the opening of the T4 binding site. Our work provides insight into TTR binding mode preference for trans-stilbene salicylic acid derivatives as well as a framework for determining structures of TTR-ligand complexes.

description: Probabilistic logic programs are logic programs in which some of the facts are annotated with probabilities. This paper investigates how classical inference and learning tasks known from the graphical model community can be tackled for probabilistic logic programs. Several such tasks such as computing the marginals given evidence and learning from (partial) interpretations have not really been addressed for probabilistic logic programs before. The first contribution of this paper is a suite of efficient algorithms for various inference tasks. It is based on a conversion of the program and the queries and evidence to a weighted Boolean formula. This allows us to reduce the inference tasks to well-studied tasks such as weighted model counting, which can be solved using state-of-the-art methods known from the graphical model and knowledge compilation literature. The second contribution is an algorithm for parameter estimation in the learning from interpretations setting. The algorithm employs Expectation Maximization, and is built on top of the developed inference algorithms. The proposed approach is experimentally evaluated. The results show that the inference algorithms improve upon the state-of-the-art in probabilistic logic programming and that it is indeed possible to learn the parameters of a probabilistic logic program from interpretations.

Religious or Secular Politics in The Turkish Republic: laicism and secularism

description: This thesis studies the interaction between religion and politics in Turkey. The problematic examined is whether, in the context of Turkish history and politics, these two fields of human endeavour are autonomous from each other. The secondary question examined is whether Turkey can be described as a secular/laic state. As the Turkish society throughout the Republic’s history underwent radical transformations, first transitioning to a secular society and then to a “post-secular” one, the nature and effect of these changes is an important area of social inquiry. The current political and social milieu and group conflicts in Turkey can only be understood in the larger context of the Republic’s history. The thesis examines the foundation principles of Turkey, including various competing narratives, and whether these principles have been properly applied and sustained. My main argument is that in contemporary Turkey the fields of religion and politics are indistinguishable, nationalism acting as a conduit. This is not necessarily a unique situation. These boundaries are porous in other societies as well. Turkey is a particularly intriguing society through which to study the interaction between the two fields because no Muslim majority country went to the length the Kemalists did, to achieve laicism and secularisation. I also argue that laicism has not been very successful, although the early Republican Kemalist state made enormous efforts to implement secularisation as part of westernisation and modernisation, the three-pillar strategy. The process of secularisation was followed by the process of de-secularisation as the tight grip of Kemalism loosened and the power of the Islamists grew. I argue that, while the de-secularisation process has been underway for some time, the secular has not disappeared but coexists with the non-secular in a hybrid form: “practical secularity” (as opposed to ideological secularity). Finally, I also argue that the Republican system established the founder Mustafa Kemal’s hegemony. This Kemalist hegemony was gradually replaced by the hegemony of Islamist Recep Tayyip Erdoğan and his Justice and Development Party (Adalet ve Kalkınma Partisi). The Kemalist and the Islamist narratives are examined in light of a variety of primary and secondary sources in several languages to construct a cohesive and analytical account of the Republic, tying it to the theoretical material related to the themes of the thesis.
