Paradigmatic Change in Gendered Labor Market Policies in Turkey

This article examines the question of how gender-related labor policy in Turkey has changed during the AKP government since the early 2000s. The focus is primarily on understanding the changing direction of public policies and institutional amendments in Turkey under the AKP government from 2002 to 2017. The findings reveal a paradigmatic change in the labor policies targeted at women. New policies are characterized by protecting and prioritizing the family, while introducing precarious flexible female labor to the market. The research contributes to the literature by providing a link between policy studies and gender research

For Women in Turkey, the Struggle Continues

As of today, the Istanbul convention ceases to be effective in Turkey. But that’s not the end of the story

Non-linear finite element analysis for prediction of seismic response of buildings considering soil-structure interaction

The objective of this paper focuses primarily on the numerical approach based on two-dimensional (2-D) finite element method for analysis of the seismic response of infinite soil-structure interaction (SSI) system. This study is performed by a series of different scenarios that involved comprehensive parametric analyses including the effects of realistic material properties of the underlying soil on the structural response quantities. Viscous artificial boundaries, simulating the process of wave transmission along the truncated interface of the semi-infinite space, are adopted in the non-linear finite element formulation in the time domain along with Newmark's integration. The slenderness ratio of the superstructure and the local soil conditions as well as the characteristics of input excitations are important parameters for the numerical simulation in this research. The mechanical behavior of the underlying soil medium considered in this prediction model is simulated by an undrained elasto-plastic Mohr-Coulomb model under plane-strain conditions. To emphasize the important findings of this type of problems to civil engineers, systematic calculations with different controlling parameters are accomplished to evaluate directly the structural response of the vibrating soil-structure system. When the underlying soil becomes stiffer, the frequency content of the seismic motion has a major role in altering the seismic response. The sudden increase of the dynamic response is more pronounced for resonance case, when the frequency content of the seismic ground motion is close to that of the SSI system. The SSI effects under different seismic inputs are different for all considered soil conditions and structural types

RECEIVED SNR BASED CODE AND ANTENNA/RELAY SELECTION FOR LIMITED FEEDBACK COMMUNICATION

Sınırlı geribeslemeli çok-girdili çok-çıktılı (ÇGÇÇ) haberleşme sisteminde kod seçimi ve verici anten seçimi yaygın olarak kullanılır. Eğer vericideki bir antenin kanal kazancı diğer antenlerin kanal kazançlarına göre çok büyükse verici anten seçimi kullanmak alıcıdaki Sinyalin Gürültüye Oranı (SGO)'nı artırır. Buna karşılık, vericideki antenlerin kanal kazançları birbirlerine yakın değerlerde ise kod seçimi kullanmak alıcıdaki SGO'yu arttırır. Bu makalede, ÇGÇÇ haberleşmesinde alıcıdaki SGO'yu arttırmak için uyarlamalı kod ve anten seçimi önerilmiştir. Bu teknikte, fazladan bir bitlik geribesleme kullanılarak verici anten seçimine ve kod seçimine göre alıcıda daha iyi bir SGO değeri elde edilir. Detaylı benzetimler göstermiştir ki, üç verici anten için uyarlamalı kod ve anten seçiminde kullanılacak 4 bitlik geribesleme, kod seçimi olarak kullanılan genişletilmiş dengeli uzay-zaman blok kodlamanın ideal geribesleme başarımını elde etmektedir. İdeal geribesleme ise kanal durum bilgisinin vericide tam olarak bilinmesini gerektirir. Ayrıca, önerilen teknik işbirlikli haberleşmeye uygulanmış ve benzer başarım artışı sağlanmıştır. Önerilen tekniğin ÇGÇÇ ile işbirlikli haberleşmesine uygulanmasındaki fark, anten seçimi yerine röle seçiminin yapılmasıdır. Code selection and transmit antenna selection are widely used in limited feedback multi input multi output (MIMO) communication system. When one of the antenna channel gains is much higher than the other antenna channel gains; using antenna selection method increases received Signal-to-Noise Ratio (SNR) at the receiver. However, when antenna channel gains are close to each other; using code selection method increases the received SNR at the receiver. In this paper, we propose an adaptive code and antenna selection scheme to increase the received SNR at the destination for MIMO system. In this technique, using one additional feedback bit yields improved SNR at the destination compared to using solely code or transmit antenna selection method. Detailed simulations show that adaptive code and antenna selection with four bit feedback yields a performance of the extended balanced space-time block coding with ideal feedback which requires exact channel state information at the transmitter. In addition, the proposed technique is applied into the cooperative communication and similar performance improvement is observed. The difference between MIMO and cooperative communication is using relay selection instead of antenna selection

“Return of the repressed”: Exposure to police violence increases protest and self-sacrifice intentions for the Yellow Vests

Worldwide, it is not uncommon to observe violent police reactions against social movements. These are often rationalized by decision makers as efficient ways to contain violence from protesters. In France for instance, the ongoing Yellow Vests protests have generated an unprecedented number of casualties, injuries, and convictions among protesters. But was this response efficient in diminishing violence stemming from the Yellow Vests? To this day, little is known about the psychological consequences of police violence in the context of protests. Combining insights from Significance Quest Theory and the Social Identity perspective on collective action, we predicted that exposure to police violence could “backfire” and lead to increased radicalization of protesters. A cross-sectional investigation of 523 Yellow Vests yielded evidence for this hypothesis. We found positive direct effects of exposure to police violence on intentions to attend future demonstrations and to self-sacrifice for the Yellow Vests. Moreover, these effects were serially mediated by perceived Loss of Significance and Identification with the Yellow Vests. Paradoxically, these results highlight for the first time the mechanism through which political repression may contribute to the formation of radical politicized identities. Thus, we recommend that decision makers privilege the use of de-escalation techniques in protest policing whenever possible. </jats:p

Inverse Layer Dependence of Friction on Chemically Doped MoS_{2}

We present the results of atomic-force-microscopy-based friction measurements on Re-doped molybdenum disulfide (MoS2). In stark contrast to the seemingly universal observation of decreasing friction with increasing number of layers on two-dimensional (2D) materials, friction on Re-doped MoS2 exhibits an anomalous, i.e. inverse dependency on the number of layers. Raman spectroscopy measurements revealed signatures of Re intercalation, leading to a decoupling between neighboring MoS2 layers and enhanced electron-phonon interactions, thus resulting in increasing friction with increasing number of layers: a new paradigm in the mechanics of 2D materials.Comment: 15 pages incl.

Combined approach of density functional theory and quantum Monte Carlo method to electron correlation in dilute magnetic semiconductors

We present a realistic study for electronic and magnetic properties in dilute magnetic semiconductor (Ga,Mn)As. A multi-orbital Haldane-Anderson model parameterized by density-functional calculations is presented and solved with the Hirsch-Fye quantum Monte Carlo algorithm. Results well reproduce experimental results in the dilute limit. When the chemical potential is located between the top of the valence band and an impurity bound state, a long-range ferromagnetic correlations between the impurities, mediated by antiferromagnetic impurity-host couplings, are drastically developed. We observe an anisotropic character in local density of states at the impurity-bound-state energy, which is consistent with the STM measurements. The presented combined approach thus offers a firm starting point for realistic calculations of the various family of dilute magnetic semiconductors.Comment: 5 pages, 4 figure
