A Minimalist Analysis of Persian Restrictive Relative Clause Derivation

Within the Minimalist Program (MP), Relative clauses (RCs) are considered complementizer clauses (CPs) containing a C with an edge feature [EF] in the form of [wh] and [EPP] but no tense feature. This study investigates Persian RC derivation based on MP. By proposing two approaches, namely: (1) ‘ke-movement’ and (2) ‘null wh-operator (OP) movement’, we will consistently argue and show that the null wh-OP approach provides an appropriate generalization for Persian restrictive RCs. Adopting the latter, the results display Persian RCs can be analyzed as CPs with a null wh-OP assuming to undertake wh-movement as copying and deletion from different syntactic positions, i.e., subject, direct object, object of preposition, etc. This operator allows a small pro in the subject position, leaving an optional null copy, either allowing an optional resumptive pronoun (RP) behind in direct object position or attaching to the verb; and obligatorily in indirect object and object of preposition positions as well as Ezafe-construction. Also, the edge feature of the probe, the complementizer ke, attracts the null wh-OP to Spec-C, for checking and valuing the unvalued [wh] and [EPP] features. The long relative clause derivations can, correspondingly, work as expected by the successive cyclic movement of OP through intermediate Spec-C positions as well

Aqueous starch as a stabilizer in zinc oxide nanoparticle synthesis via laser ablation.

Zinc oxide is a semiconductor with exceptional thermal, luminescent and electrical properties, even compared with other semiconducting nanoparticles. Its potential for advanced applications in lasers and light emitting diodes, as bio-imaging agent, in biosensors and as drug delivery vehicles, in ointments, coatings and pigments has pulled zinc oxide into the focus of various scientific and engineering research fields. Recently we started investigating if nanoparticle synthesis via laser ablation in the presence of natural stabilizers allows control over size and shape and constitutes a useful, uncomplicated alternative over conventional synthesis methods. In the current paper, we determined the ability of natural starch to act as a size controller and stabilizer in the preparation of zinc oxide nanoparticles via ablation of a ZnO plate in a starch solution with a nanosecond Q-Switched Nd:YAG pulsed laser at its original wavelength (λ = 1064 nm). Our results show that the particle diameter decreases with increasing laser irradiation time to a mean nanoparticle size of approximately 15 nm with a narrow size distribution. Furthermore, the obtained particle size in starch solution is considerably smaller compared with analogous ZnO nanoparticle synthesis in distilled water. The synthesized and capped nanoparticles retained their photoluminescent properties, but showed blue emission rather than the often reported green luminescence. Evaluation of old preparations compared with freshly made samples showed no agglomeration or flocculation, which was reflected in no significant change in the ZnO nanoparticle size and size distribution. Overall, our experimental results demonstrate that starch can indeed be effectively used to both control particle size and stabilize ZnO nanoparticles in solution

Markers of Prominence in Persian General Practitioners’ Books and Online Medical Journals

Giving certain elements more significance than others in the same context is called prominence. This study aims at identifying and comparing markers of focal and thematic prominence in Persian general       practitioners’ books (GPBs) and Persian online medical journals (OMJs) based on Levinsohn’s model. The data were gathered from 100 texts from two written Persian GPBs and 100 texts from two Persian OMJs. SPSS software version 24 was used to evaluate the data. Results demonstrated “emphatic   markers” such as fæqæt ‘just’ were used for focal prominence much more frequently in OMJs than in GPBs. In addition, significant differences were observed between GPBs and OMJs with regard to the markers of focal prominence and prominence in general, but not with regard to markers of thematic prominence. This may be related to the twofold effect of the different discourse types and different addressees of these texts

Typology of Case-marking and Agreement Systems in Bashāgardi

Based on linguistic typology approach and after analyzing the case-marking and agreement systems in (North and South) Bashāgardi according to Comrie (1978) and precise evaluation of findings according to the new theory of Zwart and Lindenbergh (2021), the present study aims to achieve a deeper explanation for those two systems’ function as well as the general alignment pattern of this dialect. In this regard, the research data has been gathered by interviewing ten native speakers, and then has been analyzed. According to the first findings, (North and South) Bashāgardi case-marking and agreement in non-past tense belong identically to the dominant and major pattern of (complete) accusative pattern, and in the past obey the dominant and shifting pattern of split-ergative or (complete) ergative pattern. Explanation of findings reveals that (North and South) Bashāgardi’s general alignment system uses the reverse and identical patterns in non-past and past tenses, respectively. Moreover, conditioned by the two categories of transitivity and tense, as the mirrors of inter-domain interrelations, these two language varieties exploit identical recessive and shifting alignment patterns in those two tenses as well, for which the appropriate explanations has been presented

Examining the frequency of dysphagia and the predictive factors of dysphagia that require attention in patients with Parkinson's disease

Introduction. Due to the prevalence of dysphagia in patients with Parkinson's disease (PD) and its complications such as aspiration pneumonia, which is the main cause of death in these patients, PD-related disability can be prevented by early diagnosis and treatment of dysphagia. Objective. The present study was aimed at investigating the frequency of dysphagia in PD patients. Materials and methods. This cross-sectional study included 150 PD patients visiting a Neurology Clinic. The severity of PD was determined based on the Unified Parkinson Disease Rating Scale (UPDRS) and modified Hoen and Yahr (HYS) Scale. The Munich Dysphagia Test-Parkinson's disease (MDT-PD) questionnaire was used to assess dysphagia. Comparisons were made using generalized Fisher exact, Chi-square, ANOVA, and KruskalWallis tests. Predictive factors were analyzed using logistic regression. Statistical analyses were performed at significance level of 0.05. Results. Out of all 150 patients referred to the Clinic, the prevalence of dysphagia requiring attention was 25.3% (n = 38). The patients of the three groups according to the MDT-PD (no noticeable dysphagia, noticeable oropharyngeal, and dysphagia with aspiration risk) had a significant difference only in terms of the PD duration (p 0.001). In the predicting of dysphagia, the longer PD duration (p = 0.011) and homemaker occupation (p = 0.033) were protective factors, while female gender was a risk factor (p = 0.011). Conclusion. The prevalence of dysphagia requiring attention in the studied patients was 25.3%. It decreased with the longer duration of the disease, and its prevalence was lower in homemaker patients, while the odds of dysphagia was 5.8 times higher in women than in men

Relationship between phonological and geographical distance: Persian, Sarawani Balochi and Sistani dialect

This article focuses on the study of geographical variations among the phonological systems of Standard Persian (SP) language, Central Sarawani Balochi (CSB), a dialect of Balochi language and the Sistani dialect (SD) of Persian, based on Optimality Theory (OT) and van Oostendorp‟s (2008) approach. SP and SD are linguistically closely related, but SP and CSB are very farther apart. While these language varieties share some similarities in their phonological system, they also have some peculiarities and are spoken in different geographical locations in Iran. Following OT and van Oostendorp‟s (2008) approach, the study of syllable structure of SP, CSB and SD supports the fact that the linguistic distance between two dialects is the minimal number of minimal reranking needed to get from one grammar to another. The findings of the present research show the fact that reranking DEP-IO and *COMPLEXONS constraints supports how the initial clusters are realized in the syllable structure of CSB and SD, but not in SP. In addition, the analysis of the status of [] in the onset position of the syllable structure of SP and SD based on the constraints: DEP-IO, ONSET and MAX-IO indicates that all these language varieties are among languages which typologically do not permit onset-less syllables. Moreover, the data suggests that the linguistic distance between two languages or dialects equals to the geographical distance between them. Further, as to syllable structure, historical considerations should be taken into account. Accordingly, the syllable structure of SD corresponds to the syllable structure of CSB rather than SP, although linguistically SD is closer to SP not CSB

Online Text Processing: A Study of Iranian EFL Learners’ Vocabulary Knowledge

The internet has developed into an important source of knowledge in recent times. It is used not just for engaging and entertaining users, but also for promoting language learning, especially for English as a Second/Foreign Language (ESL and EFL) learners spending long hours using internet, 85% of all web pages are in English. This experimental research investigated EFL learners’ experiences of vocabulary learning while surfing and text processing. In this small-scale study, two homogeneous groups of EFL learners (N=19), after taking a vocabulary test to ensure that their vocabulary knowledge differences were not significant, were randomly assigned to attend Interchange 3 class in two different groups – one as the Experimental and the other as the Control Group. Each session, there was a free discussion on special topics; while the Experimental Group surfed the internet, processed the online texts, shared and discussed their findings and beliefs on the internet, the Control Group did not use the internet and simply shared their opinions and discussed their personal beliefs. The results of the vocabulary pre- and post-tests indicated that the “internet users” significantly outperformed the “non-internet users”, that is, the Control Group. Based on the findings, internet creates a stimulating environment which helps learners effectively boost their vocabulary knowledge

Identity: a cohesive device in some Persian live sport radio and TV talks

Identity is a cohesive device that helps to have a better understanding of speech. This article analyzes the identity device and its sub-sets in some Persian live sport radio and TV programs. The theoretical framework of this research is Dooley and Levinsohn (2001). A data-driven approach based on the access to the detailed discourse context was used to have a reliable sample for the research. So, around 200 minutes of 20 different live sport radio and TV programs were transcribed. The authors present the identity extent of functionality via comparing its degree of frequency employing the SPSS software while evaluating the meaningfulness of differences in application of each of its sub-categories. This evidence-oriented research supports that the subcategories of identity can also be studied in Persian in the same way as Dooley and Levinsohn’s (2001) view among which pronouns receive the most frequency whereas pro-forms do the least. Pronouns and ellipsis contain a meaningful difference between their application in radio and TV data. In addition, there is not any significant difference between the applications of repetition, substitution and other pro-forms. Finally, identity is reported as having a significant relation in its application in the research corpora.
