Routes to collective action among opposition voters: Testing efficacy, anger, and injustice in Turkey’s repeated elections
No full textPolitical elections can set the scene for strong political identifications and increased motivation for collective action, especially in the context of contentious post-election politics. Deriving from a large literature on collective action and social identities, we focus on collective action intentions following the 2015 parliamentary elections in Turkey. This was a critical period of escalated tension between left and right as well as conservative, secular, and liberal groups in Turkey. It was also unique because the election was repeated after five months due to the parliamentary failure to form a coalition. In the context of the 2015 elections, we ask whether and how diverse political identifications drive collective action intentions via anger and political efficacy. Considering the cancellation of the first election results as a source of contention, we tested the role of perceived injustice for political identifications to predict collective action intentions through anger and efficacy following the second election.We collected panel data in two waves following each election and we focused on opposition voters of secular, liberal and/or left-wing parties in the parliamentary elections in June 2015 (N = 500) and November 2015 (N = 363). Findings of mediational path analyses indicate that different political identifications among opposition voters may alternate anger and efficacy paths to future collective action intentions in consecutive elections. By looking at elections as a critical period for future mobilisation of politicised voters dissatisfied with elections results, we underline the importance of political identifications in driving collective action intentions in a repressive context.<br/
Missing the good old days:Investigating outgroup attitudes through collective nostalgia and global identification
No full textCollective nostalgia is a group-based emotion that refers to the longing for the “good old days” of one's ingroup. Research shows that collective nostalgia usually benefits relationships with other in-group members, while hampering intergroup relations. However, this depends on the past remembered. Moreover, global identification predicts positive intergroup relations, yet this depends on whether the target group is perceived to be aligned with a global culture. Accordingly, we tested how collective nostalgia and global identification can then be linked to inclusionary vs. exclusionary outgroup attitudes in Turkey in relation to Kurds, Armenians, LGBTQ+ individuals and Syrian refugees. The results showed (N = 1090) that collective nostalgia was related to positive attitudes towards Kurds, Armenians and gay men, whereas it was negatively related to attitudes towards Syrian refugees. Moreover, contrary to expectations, we found that global identification predicted positive attitudes towards all outgroups. These findings are not surprising given the changing political climate and increasing intergroup conflict in Turkey. We speculate that the meaning attributed to the “good old days” of Turkey predicted these positive attitudes except for Syrian refugees who are perceived to be today's problem. Overall, the relationship between nostalgia and outgroup attitudes are more complex than research has so far shown, and the content of the past remembered might be important to understand this relationship.2-s2.0-85138517165Eylü

Electronic Structure of Conventional Slater Type Antiferromagnetic Insulators: AIrO<sub>3</sub> (A=Sr, Ba) Perovskites
No full textAbstract
The structural, mechanical, and electronic properties of Perovskite BaIrO3 and SrIrO3 compounds based on the density functional theory (DFT) have been examined in four different structures (C2/c, R-3m, P6_3/mmc and Pm-3m) and Pnma structure, respectively. The spin polarized generalized gradient approximation has been used for modeling exchange-correlation effects. As a result of spin polarized calculations, it has been observed that BaIrO3 compound showed magnetic properties in C2/c and R-3m structures, but not in Pm-3m and P6_3/mmc structures. SrIrO3 compound also shows magnetic properties in Pnma structure. The elastic constants have been calculated using the strain-stress method and the other related quantities (the bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, anisotropy factor, sound velocities, and Debye temperature) have also been estimated. In electronic band structure calculations, while Pm-3m and P6_3/mmc structures of NaIrO3 compound are metallic and semiconductor (Eg = 1.190 eV indirect), respectively, while C2/c and R-3m structures showing magnetic properties are metallic in spin down state and semiconductor (Eg=0.992 eV indirect and Eg=0.665 eV direct, respectively) in the spin up state. The Pmna structure in the SrIrO3 compound is a semiconductor in both spin states (Eg=0.701 eV “0.632 eV” indirect in the spin up “spin down”).</jats:p
The structural, mechanical, electronic, and optical properties of multiferroic LiCu2O2 under different pressures
No full textIn this work, the structural, mechanical, and electronic properties of LiCu2O2 compound under different pressures were studied using the density functional theory. The spin-polarized generalized-gradient approximation has been used for modelling the exchange-correlation effects. In particular, the electronic structure under zero pressure was analysed using both conventional GGA-PBE and meta-GGA (mBJLDA) functional. The structural optimization was performed by using VASP-code, and the lattice parameters and magnetic moments were calculated. Bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, anisotropy factors, sound velocities, and Debye temperature were obtained from the calculated elastic constants for LiCu2O2 compound. While the electronic band structures obtained from both functionals for spin up under zero pressure are semiconductor in nature, the electronic band structures obtained from PBE and mBJLDA functionals for spin down are narrow semiconductor and semiconductor, respectively. For the spin-up state, the Eg value decreases linearly after 5 GPa, while the Eg value increases linearly for the spin-down state. The real and imaginary parts of the dielectric function along the x, y, and z axes and the optical constants, such as the energy loss function, refractive index, reflectivity coefficient, and extinction coefficient are also calculated and presented
First-principles study of the structural, elastic, electronic, optical, and vibrational properties of intermetallic Pd2Ga
No full textWOS: 000301341400059The structural, elastic, electronic, optical, and vibrational properties of the orthorhombic Pd2Ga compound are investigated using the norm-conserving pseudopotentials within the local density approximation in the frame of density functional theory. The calculated lattice parameters have been compared with the experimental values and found to be in good agreement with these results. The second-order elastic constants and the other relevant quantities, such as the Young's modulus, shear modulus, Poisson's ratio, anisotropy factor, sound velocity, and Debye temperature, have been calculated. It is shown that this compound is mechanically stable after analysing the calculated elastic constants. Furthermore, the real and imaginary parts of the dielectric function and the optical constants, such as the optical dielectric constant and the effective number of electrons per unit cell, are calculated and presented. The phonon dispersion curves are derived using the direct method. The present results demonstrate that this compound is dynamically stable
An ultra-wide band low-SAR flexible metasurface-enabled antenna for WBAN applications
No full textIn this study, an ultra-wideband low-specific absorption rate (SAR) flexible metasurface-enabled wearable antenna is proposed for wireless body area network applications. The antenna and metamaterial (MM) structure were designed and analyzed using a commercial electromagnetic simulation software program which uses a finite integration technique solver. The antenna is designed and fabricated on a jeans textile substrate in the size of 58 x 80 x 1 mm(3). Moreover, MM reflector was designed on a felt textile substrate to reduce the SAR effect of the antenna and to increase the antenna performance (such as impedance matching, radiation pattern, and realized gain) parameters. Designed and fabricated antenna parameters and the SAR value results with and without MM are investigated. The simulated peak SAR values when the antenna with MM is placed on the body model are 0.86, 0.198, and 0.103 W/kg at frequencies of 4 GHz, 7 GHz, and 10 GHz, respectively, for 10 g of tissue. The simulated peak SAR value of the antenna with MM is also reduced by a percentage of 97, compared to the simulated peak SAR value of the antenna without MM. The peak SAR values of the antenna were less than the European safety limit of 2 W/kg for 10 g of tissue when the MM was used as an isolator. Furthermore, the simulated peak realized gain value of the antenna with the MM was increased by 98% (from 4.6 to 9.1 dB) compared to the simulated peak realized gain value of the antenna without MM. Simulation and measurement results showed that performance characteristics and peak SAR values of the proposed antenna were suitable and safe for wearable technologies
