Narcissism and the strategic pursuit of short-term mating : universal links across 11 world regions of the International Sexuality Description Project-2.

Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of 30,470 people across 53 nations spanning 11 world regions (North America, Central/South America, Northern Europe, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, Southeast Asia, and East Asia) were used to evaluate whether narcissism (as measured by the Narcissistic Personality Inventory; NPI) was universally associated with short-term mating. Results revealed narcissism scores (including two broad factors and seven traditional facets as measured by the NPI) were functionally equivalent across cultures, reliably associating with key sexual outcomes (e.g., more active pursuit of short-term mating, intimate partner violence, and sexual aggression) and sex-related personality traits (e.g., higher extraversion and openness to experience). Whereas some features of personality (e.g., subjective well-being) were universally associated with socially adaptive facets of Narcissism (e.g., self-sufficiency), most indicators of short-term mating (e.g., unrestricted sociosexuality and marital infidelity) were universally associated with the socially maladaptive facets of narcissism (e.g., exploitativeness). Discussion addresses limitations of these cross-culturally universal findings and presents suggestions for future research into revealing the precise psychological features of narcissism that facilitate the strategic pursuit of short-term mating

En este estudio se han usado respuestas de la encuesta transcultural de 30.470 personas de 53 naciones de 11 regiones mundiales (América del Norte, América del Sur/América Central, Europa del Norte, Europa del Oeste, Europa del Este, Europa del Sur, Oriente Próximo, África, Asia del Sur/Sudoeste de Asia, Asia del Este y Oceanía) para evaluar si el narcisismo (medido por el Inventario de Personalidad Narcisista; NPI) se asocia panuniversalmente con los indicadores del emparejamiento a corto plazo, tanto en la dirección, como en la intensidad. Los resultados sugieren que el narcisismo (incluidos muchos aspectos suyos medidos por el NPI) tiene las mismas asociaciones básicas con los rasgos de personalidad relacionados con el sexo (p. ej. extraversión alta) y con los resultados sexuales claves (p. ej. búsqueda más activa de las estrategias del emparejamiento a corto plazo) a través de las 11 mayores regiones mundiales del PDSI 2. La discusión se enfoca en las implicaciones y limitaciones del estudio actual

The Sign of the Dzyaloshinskii-Moriya Interaction in R-3c Symmetries

The Dzyaloshinskii–Moriya (DM) interaction is a type of exchange-coupling between twospins that can have significant effects on the properties of magnetic materials. Its magnitudeis usually small, but its direction is often a decisive factor in the determination ofthe system’s chirality. A better understanding of the spin–orbit interaction and its implicationshave been a particular target of condensed matter research over the past decade:multiferroics, topological insulators, and Rashba and Dresselhaus spin–orbit coupling areall intensively studied. Recently in Nature Physics, V. Dmitrienko and colleagues havefound a way to measure the sign of the coupling vector, in order to determine the directionof the DM interaction, using sophisticated techniques based on synchrotron spectroscopy.In this Master thesis, the sign of the DM interaction is determined in hematite (alpha-Fe2O3)and rhodochrosite (MnCO3) single crystals with R-3c symmetry by means of polarizedneutron diffraction (PND).The theoretical basis for the DM interaction, based on a symmetry analysis in both compounds,is introduced. The polarized single crystal diffraction theory and its methodsare briefly presented. A dedicated PND setup, using a new symmetric-field high Tc superconductingmagnet with a maximal field of 2.2T in combination with a 3He polarizerand Mezei-type flipper, has been developed. The corresponding numerical simulationsand optimization for each component are presented and the complete setup is successfullytested and calibrated.This new PND setup is used to collected flipping-ratio (FR) data as function of the appliedmagnetic field and temperature for both compounds. The measured data were evaluatedaccording to the theoretical basis provided in the first part of this thesis. In addition, anadvanced approach for the reconstruction of maximum entropy spin density maps fromFR data is presented and appropriate software tools developed. Using these softwaretools, 3D spin density maps are build for the paramagnetic and antiferromangetic phase,in both compounds for the first time, revealing new features compared to the results fromconventional maximum entropy software.The analysis of the obtained spin density distribution maps showed clearly on one sidethat the origin of the magnetic scattering is not the localized moments at the atomic positions,but rather magnetic fields of the displaced orbitals. On the other side, 3D mapsallowed the extraction of the sign of the DM interaction

SNP FileScanner - Tool for time dependent polarization corrections of polarized diffraction data

The scattered intensity in polarized neutron diffraction depends strongly on the beam polarization and the analyzing efficiency. In order to obtain accurate values, especially for magnetic contributions, a precise knowledge of the polarization parameters as well as correction for the finite polarization/analyzing efficiency are required. A new software tool, called “SNP FileScanner”, has been developed to simplify the data treatment for polarized neutron diffraction measurements performed using MEOP spin filter cells (SFC) on POLI [1]. The software tool performs three tasks:The first one is to organize the ³He SFCs used during the experiment. It allows to automatically extract the typical SFC parameters (Relaxation time and ³He start polarization with error bars) by fitting the observed experimental transmission data. It detects automatically changes in the monochromator settings, which can influence the measured transmission for the SFCs, and takes them into account.The second task is to correct spherical neutron polarimetry (SNP) data. It can automatically read out background-peak-background scan files from NICOS for the individual SNP channels and correct the observed peak intensity for the finite polarization provided by the SFC specified in the first part. It calculates and displays the components of the nuclear and magnetic structure factors (NN*, MyMy*, MzMz*, Re[NMy*], …) and the corrected polarization matrix with error bars. Since these structure factors are determined by a least square fit to the data, corresponding R values and a plot of the measured and calculated intensities is shown.As third task, the software can correct flipping ratios and asymmetry values from spin flip measurements according to the SFC parameters provided by the first part. The software package itself is written in Qt (C++) and uses only QCustomPlot as third party library. It can be easily extended to process measurement data from other instruments.[1] V. Hutanu, M.
