The purpose of the article is to study scientific research on history Bedřich Smetana's opera “The Bartered Bride”. methodology work includes: source – for literature and periodicals B. Bride”; historical consider at different times; generalising updating specifying basic information about specified opera. novelty lies in fact that analysis foreign sources subject this was conducted first time....

This paper investigates the impact of income shocks and bride price on early marriage in Turkey. Weather provide an exogenous source variation household through agricultural production. A decrease rainfall observed over 9 months period corresponding to growing season is found negatively affect both production returns for majority crops vegetables. Data weather are merged with individual level d...

An observableW that distinguishes all the unentangled states from some entangled states is called a witness. We consider witnesses on n qbits, and use the following normalization: A witness W satisfies |tr(Wρ)| ≤ 1 for all separable states ρ, while kWk > 1, with the norm being the maximum among the absolute values of the eigenvalues of W . Although there are n-qbit witnesses whose norm is expon...

We consider entanglement witnesses arising from positive linear maps which generate exposed extremal rays. We show that every entanglement can be detected by one of these witnesses, and this witness detects a unique set of entanglement among those. Therefore, they provide a minimal set of witnesses to detect all entanglement in a sense. Furthermore, if those maps are indecomposable then they de...

This research examined the impact of eyewitness identification decisions on student-investigators. Undergraduates played the role of police investigators and interviewed student-witnesses who had been shown either a good or poor view of the perpetrator in a videotaped crime. Based on information obtained from the witness, student-investigators then chose a suspect from a database containing inf...

Background Bride-trafficking has been a growing phenomenon in Southeast Asia, particularly in China, where one-child policies have resulted in demographic imbalances favoring males. Yet, empirical evidence about women and girls sold into marriage in China remains sparse. Methods This study describes the experiences of 51 Vietnamese women and girls as young as 14 in post-trafficking services w...
