Boij-S\"{o}derberg Decompositions of Lex-segment Ideals

Boij-S\"oderberg theory describes the scalar multiples of Betti diagrams of graded modules over a polynomial ring as a linear combination of pure diagrams with positive coefficients. There are a few results that describe Boij-S\"oderberg decompositions explicitly. In this paper, we focus on the Betti diagrams of lex-segment ideals and describe the Boij-S\"oderberg decomposition of a lex-segment ideal in terms of Boij-S\"oderberg decompositions of some other related lex-segment ideals.Comment: The proof of Theorem 1.2 is improve

Functional textile preferences of elderly people

Aging is an inevitable stage of lifetime bringing along physical and emotional deterioration. Rate of aging population in the world has been constantly rising with the contribution of technological improvements on life quality, and medical services.

Ethnic identity and perceptions of the police in Turkey: the case of Kurds and Turks

Drawing on the literature on minorities’ and ethnic groups’ perceptions of the police, this article investigates the differences between Kurds and Turks in terms of their perceptions of the police in Turkey. We conducted survey research using a nationally representative sample of 1804 people. Multivariate regression analysis revealed that Kurds in Turkey have a more negative perception of the police than Turks, regardless of their gender, education, income, party affiliation, and sectarian identity. It is concluded that the historical relationship between Kurds and the Turkish state has had a decisive effect on how Kurds perceive the police
