آموزش از دور، ارزشیابی، دوره متوسطه، الگوی nade-tdec.
هدف این پژوهش ارزشیابی برنامههای آموزش از دور در دوره متوسطه شهر تهران از نظر فراگیران بر اساس الگوی NADE-TDEC میباشد. روش پژوهش توصیفی از نوع پیمایشی میباشد. ابزارگردآوری اطلاعات، پرسش نامهای پژوهشگر ساخته برگرفته از الگوی NADE-TDEC به تعداد 40 گویه بسته پاسخ با پایایی 882/0 با طیف لیکرت پنج درجهای میباشد. جامعه آماری شامل 16275 نفر دانشآموز شاغل به تحصیل در 54 مرکز آموزشی از دور در دور...
پژوهش حاضر با هدف، ارزیابی کیفیت برنامههای آموزشی دانشگاه پیام نور قم بر اساس الگوی (NADE-TDEC) انجام شد. روش پژوهش توصیفی و رویکرد آن نیز کاربردی است. از میان همة دانشجویان شاغل به تحصیل در دانشگاه پیام نور قم (14232 نفر) 375 دانشجو به روش نمونهگیری تصادفی سهمیهای به عنوان نمونه پژوهش انتخاب شدند. ابزار جمعآوری دادهها، پرسشنامه محقق ساخته بود و دادههای حاصل نیز با استفاده از شاخصهای آما...
This paper proposes CF-NADE, a neural autoregressive architecture for collaborative filtering (CF) tasks, which is inspired by the Restricted Boltzmann Machine (RBM) based CF model and the Neural Autoregressive Distribution Estimator (NADE). We first describe the basic CF-NADE model for CF tasks. Then we propose to improve the model by sharing parameters between different ratings. A factored ve...
The most active metabolite of vitamin D, calcitriol, is growth inhibitory for various tumor types in vitro and in vivo and inhibits the growth of endothelial cells freshly isolated from tumors [tumor-derived endothelial cells (TDEC)]. We compared the effects of calcitriol on Matrigel-derived endothelial cells (MDEC) and TDEC isolated from Matrigel plugs and squamous cell carcinoma tumors, respe...
The low affinity neurotrophin receptor p75NTR can mediate cell survival as well as cell death of neural cells by NGF and other neurotrophins. To elucidate p75NTR-mediated signal transduction, we screened p75NTR-associated proteins by a yeast two-hybrid system. We identified one positive clone and named NADE (p75NTR-associated cell death executor). Mouse NADE has marked homology to the human HGR...
Nerve growth factor (NGF) can induce apoptosis in neural cells via activation of the low affinity neurotrophin receptor p75NTR. NADE (p75NTR-associated cell death executor) is a p75NTR-associated protein that mediates apoptosis in response to NGF by interacting with the death domain of p75NTR in 293T, PC12, and nnr5 cells (Mukai, J., Hachiya, T., Shoji-Hoshino, S., Kimura, M. T., Nadano, D., Su...
Calcitriol (1,25-dihydroxycholecalciferol), the major active form of vitamin D, is antiproliferative in tumor cells and tumor-derived endothelial cells (TDEC). These actions of calcitriol are mediated at least in part by vitamin D receptor (VDR), which is expressed in many tissues including endothelial cells. To investigate the role of VDR in calcitriol effects on tumor vasculature, we establis...
Recently, a 22 kDa protein termed p75(NTR)-associated death executor (NADE) was discovered to be a necessary factor for p75(NTR)-mediated apoptosis in certain cells. However, the possible role for p75(NTR)/NADE in pathological neuronal death has yet been undetermined. In the present study, we have examined this possibility in vivo and in vitro. Exposure of cortical cultures to zinc induced both...
Sphingomyelin metabolism in rat liver after chronic dietary replacement of choline by N-aminodeanol.
Sphingomyelin (SM) is a structural element of cell membranes and lipoproteins, and participates in signal transduction. To determine whether a choline analog (N-amino-N,N-dimethylaminoethanol, N-aminodeanol, NADe) can be substituted for choline in the SM of liver, rats (male, Sprague-Dawley-derived) were fed a diet that was low in choline and methionine, and contained 35.5 mmol of NADe/kg. Afte...
