- چکیده:
- چکیده انگلیسی: 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. The present study has investigated some of the youth's socio-economic challenges and its denotation for marriage and childbearing ideals among the youth of Sanandaj city. The research data was raised from survey method that collected from 240 young persons aged 15-29 with a questionnaire. The analysis of the data is indicated that employment, monetary-economic problems, educations, marriage and the lack of clear outlook about future are the most important challenges of the youth in the region. Of course, these challenges were different according to people's demographic backgrounds and they are influential on their marriage and childbearing ideals too. Finally, in this regard, it has suggested that government and other involving organizations should be pace in removal of the youth's problems insistently and give the much attention and endeavor to this enormous stratum and valuable potency of the society.

- چکیده:
- چکیده انگلیسی: The current study was an attempt to investigate the impact of grouping type on the grammatical accuracy of Iranian EFL learners in collaborative writing. Through administering the Michigan Test of English Language Proficiency, 64 female university students available participated in this study and were assigned to two groups--heterogeneous and homogeneous. The treatment process lasted 12 weeks of collaborative writing and revising, with emphesis on the development of the the participants’ written grammatical accuracy. They were pretested and posttested through a descriptive free writing measure. The results revealed that the participants in both groups had higher posttest scores. Using ANCOVA, it was found that there was a differential effect of grouping type on the grammatical accuracy of homogeneous and heterogeneous pairs, indicating that the participants in heterogeneous group had significantly higher posttest scores than those in homogeneous group. Furthermore, although the grammatical accuracy of both groups increased, a significant difference was observed between them, revealing that the participants in heterogeneous group outperformed those in homogeneous group. The findings of this study can be interpreted in terms of the sociocultural theory and Vygotsky’s idea of the zone of proximal development.

- چکیده:
- چکیده انگلیسی: Condition $(PWP)$ which was introduced in (Laan, V., {it Pullbacks and flatness properties of acts I}, Commun. Algebra, 29(2) (2001), 829-850), is related to flatness concept of acts over monoids. Golchin and Mohammadzadeh in ({it On Condition $(PWP_E)$}, Southeast Asian Bull. Math., 33 (2009), 245-256) introduced Condition $(PWP_E)$, such that Condition $(PWP)$ implies it, that is, Condition $(PWP_E)$ is a generalization of Condition $(PWP)$.
In this paper we introduce Condition $(PWP_{ssc})$, which is much easier to check than Conditions $(PWP)$ and $(PWP_E)$ and does not imply them. Also principally weakly flat is a generalization of this condition. At first, general properties of Condition $(PWP_{ssc})$ will be given. Finally a classification of monoids will be given for which all (cyclic, monocyclic) acts satisfy Condition $(PWP_{ssc})$ and also a classification of monoids $S$ will be given for which all right $S$-acts satisfying some other flatness properties have Condition $(PWP_{ssc})$.- انتشار مقاله: 05-12-1396

- چکیده:
- چکیده انگلیسی: In this article, we present $GPW$-flatness property of acts over monoids, which is a generalization of principal weak flatness. We say that a right $S$-act $A_{S}$ is $GPW$-flat if for every $s in S$, there exists a natural number $n = n_ {(s, A_{S})} in mathbb{N}$ such that the functor $A_{S} otimes {}_{S}- $ preserves the embedding of the principal left ideal ${}_{S}(Ss^n)$ into ${}_{S}S$. We show that a right $S$-act $A_{S}$ is $GPW$-flat if and only if for every $s in S$ there exists a natural number $n = n_{(s, A_{S})} in mathbb{N}$ such that the corresponding $varphi$ is surjective for the pullback diagram $P(Ss^n, Ss^n, iota, iota, S)$, where $iota : {}_{S}(Ss^n) rightarrow {}_{S}S$ is a monomorphism of left $S$-acts. Also we give some general properties and a characterization of monoids for which this condition of their acts implies some other properties and vice versa.

- چکیده:
- چکیده انگلیسی: Laan in (Ph.D Thesis, Tartu. 1999) introduced the principal weak form of Condition $(P)$ as Condition $(PWP)$ and gave some characterization of monoids by this condition of their acts. In this paper first we introduce Condition (G-PWP), a generalization of Condition $(PWP)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. We also give a characterization of monoids, by comparing this property of their acts with some others. Finally, we give a characterization of monoids coming from some special classes, by this property of their diagonal acts and extend some results on Condition $(PWP)$ to this condition of acts.

- چکیده:
- چکیده انگلیسی: In this paper first of all we introduce Property $U$-($G$-$PWP$) of acts, which is an extension of Condition $(G$-$PWP)$ and give some general properties. Then we give a characterization of monoids when this property of acts implies some others. Also we show that the strong (faithfulness, $P$-cyclicity) and ($P$-)regularity of acts imply the property $U$-($G$-$PWP$). Finally, we give a necessary and sufficient condition under which all (cyclic, finitely generated) right acts or all (strongly, $Re$-) torsion free (cyclic, finitely generated) right acts satisfy Property $U$-($G$-$PWP$).
