this study investigated metadiscourse and its subcategories in english research articles (ras) written by nonnative (iranian) and native english writers from the two disciplines of applied linguistics and civil engineering. the study aimed at seeing whether language and discipline influenced the frequency of occurrence of metadiscourse elements in research articles. to this end, a sample of 120...

In this thesis the global structure of three classes of algebraic triangulated categories is investigated by describing their thick, localizing and smashing subcategories and by analyzing the Smashing Conjecture. We show that the Smashing Conjecture for the stable module category of a self-injective artin algebra A is equivalent to the statement that a class of model categories associated with ...

We investigate Hochschild cohomology and homology of admissible subcategories of derived categories of coherent sheaves on smooth projective varieties. We show that the Hochschild cohomology of an admissible subcategory is isomorphic to the derived endomorphisms of the kernel giving the corresponding projection functor, and the Hochschild homology is isomorphic to derived morphisms from this ke...

Twitter has become a viable platform for spammers, who often form networks to further their reach. Troublesomely, targeted users become increasingly frustrated, or worse, view content resulting in computer virus infection. We build on previous work around detecting spam on Twitter, proposing that subcategorising spammers can increase our understanding of their connections in spammer networks an...

Quasicontinuity is a generalisation of Scott’s notion of continuous domain, introduced in the early 80s by Gierz, Lawson and Stralka. In this paper we ask which cartesian closed full subcategories exist in qCONT, the category of all quasicontinuous domains and Scottcontinuous functions. The surprising, and perhaps disappointing, answer turns out to be that all such subcategories consist entirel...

This thesis deals mainly with hereditary coreflective subcategories of the category Top of topological spaces. After preparing the basic tools used in the rest of thesis we start by a question which coreflective subcategories of Top have the property SA = Top (i.e., every topological space can be embedded in a space from A). We characterize such classes by finding generators of the smallest cor...

BACKGROUND Supporting positive mental health development in adolescents is a major public health concern worldwide. Although several school-based programs aimed at preventing depression have been launched, it is crucial to evaluate these programs and to obtain feedback from participating adolescents. This study aimed to explore adolescents' experiences with a -based cognitive-behavioral depress...

Abstract. Let R be a quotient ring of a commutative coherent regular ring by a finitely generated ideal. Hovey gave a bijection between the set of coherent subcategories of the category of finitely presented R-modules and the set of thick subcategories of the derived category of perfect R-complexes. Using this isomorphism, he proved that every coherent subcategory of finitely presented R-module...

Abstract We present the concept of cotorsion pairs cut along subcategories an abelian category. This provides a generalization complete pairs, and represents general framework to find approximations restricted certain subcategories. also exhibit some connections between Auslander–Buchweitz approximation theory, by considering relative analogs for Frobenius contexts. Several applications are giv...

background: smoking is a well‑known public health problem in women as well as men. in many countries including iran, there is an increase in tobacco use among women. exploring the experience of smoking by educated women in order to develop effective tobacco prevention programs in these women is necessary. this study aimed to explore the experiences of smoking among iranian educated women. metho...
