Today, the concept of tax compliance has become a common phenomenon in the most countries and identifying the factors which affecting on it, specially internal and psychological factors instead of economic factors, attracted the attention of a large number of researchers in all over the world. So, the purpose of this study is to present a model of tax compliance with the realization approach of...
This study seeks to model tax evasion and identify how effective factors affect tax evasion in the Iranian economy. Recent models show the failure of traditional models; Models do not have enough ability to model hidden variables such as tax evasion. The present study considers this failure in identifying explanatory variables and experimental model design. To achieve this, the Bayesian averagi...
مقدمه: پپتید وابسته به آرژنین ـ فنیل آلانین ـ آمید (rfrp) و کیس پپتین به ترتیب به عنوان مهارکننده و محرک ترشح هورمون آزاد کننده گونادوتروپین (gnrh) شناخته شده اند. هدف پژوهش کنونی مقایسه اثر شیردهی بر بیان mrnaهای rfrp-3 در هسته پشتی ـ داخلی هیپوتالاموس (dmh) و kiss-1 در هسته کمانی (arc) هیپوتالاموس موش های صحرایی شیرده و غیر شیرده بود. روش ها: چهارده موش صحرایی سویه اسپراگ ـ داولی انتخاب و به ...
مقدمه و هدف: در طی مرحله رشد در اووژنز مقدار زیادی mrna ساخته و در اووسیت ذخیره می شود سپس نسخه برداری در طی تقسیم میوز متوقف می گردد. توقف نسخه برداری در مراحل اولیه جنینی تا قبل از شروع فعالیت ژنوم جنین ادامه دارد. بنابراین، اولین وقایع سلولی در طی امبریوژنز در پستانداران و گونه های دیگر جانوری به rnaها و پروتئین های مادری ذخیره شده در اووسیت وابسته است. یکی از راه های کنترل ترجمه mrna های ما...
The existence of tax concessions (tax exemption, tax holiday, allowances …) provide the possibility of reducing tax liability via special tax provisions or regulations in tax laws for some taxpayers, hence government loses some tax revenues. Therefore, the forgone tax revenues resulting from some of the tax concessions for particular taxpayers, regions and sectors of an economy, are considere...
In this paper we characterize, both theoretically and quantiatively, the optimal mix of progressive income taxes and education subsidies in a model with endogeous human capital formation, borrowing constraints and income risk.
The traditional view that excise taxes are regressive has been challenged. I document the history of the term regressive tax, show that traditional definitions have always found cigarette taxes to be regressive, and illustrate the implications of the greater price responsiveness observed among the poor. I explain the different definitions of tax burden: accounting, welfare-based willingness to ...
Human T cell lymphotropic virus type 1 (HTLV-1) infection can lead to development of adult T cell leukemia/lymphoma (ATL) or HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in a subset of infected subjects. Understanding the interaction between host and HTLV-1 and the molecular mechanisms associated with disease pathogenesis is critical for development efficient therapies. T...
Interleukin 8 (IL-8) mRNA was detected in peripheral leukemic cells obtained from adult T-cell leukemia patients, as well as in cultured human T-cell leukemia virus type I (HTLV-I)-infected T-cell lines (HUT-102, MT-1, SALT-3, and SKT-1B). With the use of ELISA, IL-8 protein was also detected in the culture medium of these cells and in the extracellular fluids of patients. Furthermore, we demon...
X-box binding protein 1 (XBP-1), a basic leucine zipper transcription factor, plays a key role in the cellular unfolded protein response (UPR). There are two XBP-1 isoforms in cells, spliced XBP-1S and unspliced XBP-1U. XBP-1U has been shown to bind to the 21-bp Tax-responsive element of the human T-lymphotropic virus type 1 (HTLV-1) long terminal repeat (LTR) in vitro and transactivate HTLV-1 ...
