University Students Attitudes: Croatia Versus Turkey

We surveyed Croatian and Turkish business school students, from universities emphasizing globalization, to analyze whether consideration for travel to the USA is affected by attitude toward their own country and the USA The results from comparing and contrasting differences between these countries and differences between males and females in each country - and their counterparts in the other country - may also give an outlook to future business relationships between the USA and these countries. Based on a t-test, Croatian students ratings of the USA were significantly more positive, but there was no statistically significant difference in expectations to travel to the USA

University Students Perceptions Of Two Countries: Turkey And U.S.A.

This study was generated to understand how Turkish university students perceive their country and the U.S.A. and how U.S.A. university students perceive their country and Turkey. Perceptions are people's realities, and they use their perceptions to make decisions, form opinions and behave based on them. Perceptions may have tremendous impacts on the economic and political future relations for both countries. The paper was conceived and conducted by university faculty from both Turkey (Bahcesehir University, Istanbul Turkey) and the U.S.A. (Robert Morris University, Pittsburgh, PA). The authors would like to thank their colleagues who had their students complete the surveys

The Tarantula Massive Binary Monitoring: I. Observational campaign and OB-type spectroscopic binaries

© ESO, 2017.Context. Massive binaries play a crucial role in the Universe. Knowing the distributions of their orbital parameters is important for a wide range of topics from stellar feedback to binary evolution channels and from the distribution of supernova types to gravitational wave progenitors, yet no direct measurements exist outside the Milky Way. Aims. The Tarantula Massive Binary Monitoring project was designed to help fill this gap by obtaining multi-epoch radial velocity (RV) monitoring of 102 massive binaries in the 30 Doradus region. Methods. In this paper we analyze 32 FLAMES/GIRAFFE observations of 93 O- and 7 B-type binaries. We performed a Fourier analysis and obtained orbital solutions for 82 systems: 51 single-lined (SB1) and 31 double-lined (SB2) spectroscopic binaries. Results. Overall, the binary fraction and orbital properties across the 30 Doradus region are found to be similar to existing Galactic samples. This indicates that within these domains environmental effects are of second order in shaping the properties of massive binary systems. A small difference is found in the distribution of orbital periods, which is slightly flatter (in log space) in 30 Doradus than in the Galaxy, although this may be compatible within error estimates and differences in the fitting methodology. Also, orbital periods in 30 Doradus can be as short as 1.1 d, somewhat shorter than seen in Galactic samples. Equal mass binaries (q> 0.95) in 30 Doradus are all found outside NGC 2070, the central association that surrounds R136a, the very young and massive cluster at 30 Doradus's core. Most of the differences, albeit small, are compatible with expectations from binary evolution. One outstanding exception, however, is the fact that earlier spectral types (O2-O7) tend to have shorter orbital periods than later spectral types (O9.2-O9.7). Conclusions. Our results point to a relative universality of the incidence rate of massive binaries and their orbital properties in the metallicity range from solar (Z) to about half solar. This provides the first direct constraints on massive binary properties in massive star-forming galaxies at the Universe's peak of star formation at redshifts z ~ 1 to 2 which are estimated to have Z 0.5 Z
