صنعت گردشگری از اوایل دهه 70 به عنوان راهی برای کاهش کسری بودجه، منبع تامین ارز خارجی و ایجاد اشتغال مطرح شده و به عنوان صنعتی دارای تأثیرات چند بعدی مطرح است. بنابراین میتواند به عنوان یکی از ابزارهای اصلی توسعه در استان اصفهان نیز مورد توجه قرار گیرد. به منظور ارزیابی نقشی که این صنعت می تواند بر اقتصاد استان داشته باشد، در این پژوهش با استفاده از ماتریس حسابداری اجتماعی سال 1385 این استان ...
This paper addresses how financial development affects product quality and firmlevel exports depending on the firm’s productivity. To this goal, I propose a heterogeneous firms model with endogenous quality, credit constraints and heterogeneous productivity of a firm. I show theoretically and confirm empirically that lower financial constraints result in higher-quality output and higher exports...
In the course of investigating anti-DNA autoantibodies, we examined IgM and IgG antibodies to poly-G and other oligonucleotides in the sera of healthy persons and those diagnosed with systemic lupus erythematosus (SLE), scleroderma (SSc), or pemphigus vulgaris (PV); we used an antigen microarray and informatic analysis. We now report that all of the 135 humans studied, irrespective of health or...
The influential papers on the effect of credit constraints on growth and international trade (Rajan and Zingales, 1998; Manova, 2013) tend to assume that asset tangibility and the share of external borrowing are exogenous industry characteristics, which are timeand country-invariant. In the finance literature, however, the share of external borrowing is viewed as endogenous and dependent on the...
37 per cent of all human-induced methane, which is largely produced by the digestive system of ruminants, and 64 per cent of ammonia, which contributes significantly to acid rain. Livestock now use 30 per cent of the earth’s entire land surface, the report says, mostly on permanent pasture but also including 33 per cent of the global arable land — used to produce feed for livestock, the report ...
In fission yeast, the cyclin-dependent kinase (CDK) inhibitor p25(rum1) is a key regulator of progression through the G1 phase of the cell cycle. We show here that p25(rum1) protein levels are sharply periodic. p25(rum1) begins to accumulate at anaphase, persists in G1 and is destroyed during S phase. p25(rum1 )is stabilized and polyubiquitinated in a mutant defective in the 26S proteasome, sug...
In free living conditions, 24 breastfed infants, aged 6 to 10 months, were given successively five experimental gruels to study the effect of energy density (ED) and sweetness (sweet taste) on energy intakes (EI). Four gruels (G0, G1, G9 and G20) were prepared with experimental flours which were composed of the same local ingredients and which contained different levels of sucrose. The fifth gr...
هر کشوری تلاش می‌نماید تا مهمترین محصولات خود را با توجه به اقتضائات اقتصاد داخلی و اثرات مختلف بر شاخص‌هایی نظیر امنیت غذایی، معیشتی و توسعه روستای در فهرست کالاهای خاص خود بگنجاند. محدودیت چنین فهرست‌هایی باعث شده است تا کشورها ضمن اولویت‌بندی نمودن شاخص‌های تعیین شده اقدام به انتخاب مهمترین و اثرگذارترین محصولات خود نمایند. در این مطالعه با توجه به اینکه عمده معیارهای برگزیده مبتنی بر مواف...
