Iranian youth presently forms third percent of the total population. The demographic ideals and behaviors of this proportion of population play the important role in demographic phenomenon and equations of the society.

Family types continue to expand in the U.S., yet normative patterns of endogamy and the privileging of nuclear families persist. To understand how professional women of color navigate endogamy and family ideals, I draw on 40 in-depth interviews of professional Black women and Latinas to ask how they construct partner preferences.

widespread changes in women’s roles in society, in turn, leads to their increasing participation in the social arena, therefore, by increasing women’s autonomy in different aspects of life, they are more likely to reach to higher positions and status than they were in earlier decades. this situation provides the context for changes in fertility ideals (fertility behavior, desires, and ideals) o...

generalizing the concepts of -fuzzy (left, right, lateral) ideals, -fuzzy quasi-ideals and   -fuzzy bi (generalized bi-) ideals in ternary semigroups, the notions of -fuzzy (left, right, lateral) ideals, -fuzzy quasi-ideals and -fuzzy bi (generalized bi-) in ternary semigroups are introduced and several related properties are investigated. some new results are obtained.

let  $r$ be a commutative noetherian ring and $i$ be an ideal of $r$. we say that $i$ satisfies the persistence property if  $mathrm{ass}_r(r/i^k)subseteq mathrm{ass}_r(r/i^{k+1})$ for all positive integers $kgeq 1$, which $mathrm{ass}_r(r/i)$ denotes the set of associated prime ideals of $i$. in this paper, we introduce a class of square-free monomial ideals in the polynomial ring  $r=k[x_1,ld...

this paper consider the   general  forms of $(alpha,beta)$-fuzzyleft ideals (right ideals, bi-ideals, interior ideals) of an orderedsemigroup, where$alpha,betain{in_{gamma},q_{delta},in_{gamma}wedgeq_{delta}, in_{gamma}vee q_{delta}}$ and $alphaneqin_{gamma}wedge q_{delta}$. special attention is paid to$(in_{gamma},ivq)$-left ideals (right ideals, bi-ideals, interiorideals) and some related  pr...
