Between Religion and Secularity in Turkey: A Qualitative Enquiry into the Understandings and Experiences of Turkish University Students

This research explores the ways in which young Turkish university students understand, express and negotiate religious practice versus secularism in the public and private spheres as these have emerged in the early twenty-first century, in light of the historical polarization between Islamism and secularism in Turkey. Data was collected using qualitative research methodologies, including participant observation and in-depth interviews with forty-five university students in Istanbul, Turkey. This latter method allowed participants to express their perceptions and experiences about the relationship between Islam and secularity in the context of Turkey’s move to democracy, and the success of the AKP religious party in democratic elections. The thesis begins with a review of relevant scholarly literature; first, debates on the relationship between Islam and the secular state, and secularist policies of Turkey; second, social and cultural conceptions of the relationship between Islam and secularity in Turkey; third, philosophical and conceptual debates on Islam and secularity. Examining this issue, I explore (1) the perceptions and views of university students on secularism and Islamism, the secularist state and the Islamic state; (2) their understanding and experience of religiosity and secularity; (3) the impact of religious groups in Turkey on the relationship of university students with religion, secularity and modernity; (4) the divisions or cohesion of Turkish society based on religion, culture, and lifestyle. I then move on to present and examine one of the most prominent public events of Turkish politics in 2013, the Gezi Park Protests, in terms of the subject of my thesis. The thesis concludes that Turkish university students, both secular and religiously oriented, do successfully negotiate the secular spaces of the public sphere, and have developed new kinds of religiosity and Islamic understanding that stress individual choice and shape their attitudes towards the state, politics, and fellow students who choose to embrace different lifestyles

Peridynamic simulations of nanoindentation tests to determine elastic modulus of polymer thin films

This study combines atomic force microscope (AFM) nanoindentation tests and peridynamic (PD) simulations to extract the elastic moduli of polystyrene (PS) films with varying thicknesses. AFM nanoindentation tests are applied to relatively hard PS thin films deposited on soft polymer (polydimethylsiloxane (PDMS)) substrates. Linear force versus deformation response was observed in nanoindentation experiments and numerical simulations since the soft PDMS substrate under the stiff PS films allowed bending of thin PS films instead of penetration of AFM tip towards the PS films. The elastic moduli of PS thin films are found to be increasing with increasing film thickness. The validity of both the simulation and experimental results is established by comparison against those previously published in the literature

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe
