در سال های اخیر با شدت یافتن بحران مالی جهانی بسیاری از بنگاههای اقتصادی زیان های بزرگی را متحمل شده؛ و یا حتی به مرحله ورشکستگی رسیده اند بطور کلی در ایران و خصوصاً در بین شرکت های ثبت شده در بورس اوراق بهادار تهران موارد زیادی وجود دارد که از ضعف سلامت مالی رنج می برند و به بیانی دیگر در آستانه ورشکستگی هستند. این پژوهش پس از کنترل کردن متغیر هایی از قبیل (اندازه، سودآوری، فرصت های رشد پیش بین...
Recent research suggests that phonotactic probability (the likelihood of occurrence of a sound sequence) and neighborhood density (the number of words phonologically similar to a given word) influence spoken language processing and acquisition across the lifespan in both normal and clinical populations. The majority of research in this area has tended to focus on controlled laboratory studies r...
BACKGROUND AND PURPOSE Various methods for evaluating the lateralization of linguistic function using functional MR imaging have been proposed. However, the optimal method remains controversial. The purpose of this study was not only to establish a method for quantitatively evaluating the lateralization of linguistic function but also to evaluate its optimality. METHODS Internal speech tasks ...
OBJECTIVES To determine changes in height, weight, and BMI of extremely preterm (EPT; gestational age <28 completed weeks) survivors from birth to 18 years of age, compared with term controls. METHODS Birth, discharge, and follow-up at ages 2, 5, 8, and 18 years of consecutive EPT survivors and contemporaneous term controls born in 1991-1992 in Victoria, Australia. Weight, height, and BMI wer...
background: some studies have shown the possible role of protein‑energy malnutrition (pem) in persistence of endemic goiter in iodine replenished areas. the present study was conducted to assess the association between pem and goiter in schoolchildren of isfahan, iran. methods: in a cross‑sectional study using multistage cluster random‑sampling, 2331 schoolchildren with age ranged from 6‑13 yea...
Today we are riding the crest of a wave of converging new neuroscience In the physics of source localization the forward solution is where a source inside a sphere determines the electrical potential on the surface as calculated using Maxwell's 1864 equations. In contrast, the inverse problem is where the sources are unknown and the location of the sources are estimated by measuring the electri...
مقدمه : سرطان سینه از جمله شایعترین بدخیمی ها در زنان ایرانی می باشد که میزان بروز آن 09/17% در هر 100 هزار زن می باشد. میزان بقای 5 ساله این بدخیمی در حدود 75% گزارش شده است. سرطان پستان شایعترین علت مرگ در زنان پس از سرطان ریه بوده و شایعترین محل درگیری آن در ربع فوقانی-خارجی سینه می باشد. مبتلایان به سرطان سینه به دلیل مصرف داروهای مختلف از جمله مهارکننده های آروماتاز در معرض ابتلا به کاهش چ...
We conduct a field experiment to test whether (and how) emotional intelligence can be taught effectively in a short course. We randomly assign MBA students to an emotional intelligence course, a resiliency course, and a “placebo” course. We compare their emotional intelligences, as measured by the MSCEIT, before and after the sixteen-hour course. We find that students in the emotional intellige...
Pairwise and network meta-analysis (NMA) are traditionally used retrospectively to assess existing evidence. However, the current evidence often undergoes several updates as new studies become available. In each update recommendations about the conclusiveness of the evidence and the need of future studies need to be made. In the context of prospective meta-analysis future studies are planned as...
Recent studies of mammalian transcriptomes have identified numerous RNA transcripts that do not code for proteins; their identity, however, is largely unknown. Here we explore an approach based on sequence randomness patterns to discern different RNA classes. The relative z-score we use helps identify the known ncRNA class from the genome, intergene and intron classes. This leads us to a fracti...
