Within the context of event modeling and understanding, we propose a new method for neural sequence modeling that takes partially-observed sequences of discrete, external knowledge into account. We construct a sequential neural variational autoencoder, which uses Gumbel-Softmax reparametrization within a carefully defined encoder, to allow for successful backpropagation during training. The core idea is to allow semisupervised external discrete knowledge to guide, but not restrict, the variational latent parameters during training. Our experiments indicate that our approach not only outperforms multiple baselines and the state-of-the-art in narrative script induction, but also converges more quickly.

Background: Smoking causes premature and preventable death of millions of educated people. Objectives: Given the role model for medical students in the future of the country, the current study aimed at determining the smoking prevalence and its related factors among dormitory students of Shahid Beheshti University of Medical Sciences in Tehran, Iran. Methods: The current cross sectional study was conducted with descriptive-analytical approach on 355 dormitory students selected by single-stage random cluster sampling method. Data were collected using a researcher-made questionnaire including demographic and background information and smoking features. Then, data were analyzed with SPSS version. 21, using descriptive statistics and Chi-square test. Results: The current study findings indicated that 23.8% (n = 81) of the subjects were current smokers; smoking had a significant relationship with gender variables, history of probation, close friends that smoked, and employment (P < 0.05). Conclusions: In comparison to other studies, the smoking prevalence was relatively high. Therefore, the necessity of proper education about the harms and health effects of smoking are felt more than ever.

Objectives: Social development in children is influenced by several factors, including family, school friends, television, gender, race, socioeconomic status, and locomotor activity, and depending on the situation and how they react to it, social development and maturity might get accelerated or get undermined. Therefore, in this study, we aimed to investigate the relationship between fine motor skills and social development and maturity in children.Methods: This is a descriptive-analytical study that included 85 children in the age group of 6-8 years (41 boys and 44 girls). We used a two-stage random sampling method in order to select samples from elementary schools in Regions 14 and 15, Tehran. Information was collected through the General Health Questionnaire and demographic questionnaire, which was filled by the parents. Fine motor skills test consisting of three subtests, i.e. response speed, visual-motor control, and upper-limb speed and dexterity, was measured using BruninksOseretsky Test of Motor Proficiency. Social maturity was measured using Vineland social maturity scale. The entire process lasted for a month and the mean, standard deviation, range of changes, minimum, and maximum values were analyzed. Mann-Whitney test was used to compare mean scores of variables between male and female groups and significance level for statistical tests was analyzed at α=0.05. Results:Significant correlation between social quotient and total score of fine motor skills variable was obtained (P<0.001, r=0.46). A significant correlation was also observed between visual-motor control score and social quotient (P<0.001, r=0.44) and between social quotient and upper-limb speed and dexterity (P<0.001, r=0.36). However, there was no significant correlation observed between response speed and social quotient (P<0.42, r=0.08).Discussion: According to the results, there is a significant association between fine motor skills with respect to visual-motor skills of hands and social competence and maturity in children. As a result, fine motor skill can be used as an important factor along with other effective factors in improving social skills of children who have defects in the social field

The effects of gamma radiation treatment (50 and 100 Gy) on potato tubers irradiated at different days (10th, 30th and 50th) after harvest were studied during 5 months of storage at 10°C using Agria and Marfona varieties. A factorial experiment was done, based on a Randomized Complete Block Design with four replications. The 100 Gy radiation treatments on 10th and 30th days after harvest completely prevented sprouting at both varieties studied but on 50th day only Agria tubers not sprouted. This study indicated that early irradiation and absorbed radiation doses significantly decreased sprouting, percent weight loss and specific gravity of tubers. Reducing sugar content significantly increased by delay in irradiation and lower dose of radiation while non-reducing sugars did not decrease significantly by delay in irradiation and higher dose of radiation. The least increase in reducing sugars (10.2%) and most decrease in non-reducing sugar (-12.75%) were observed in tubers that irradiated on 10th day after harvest. The content of ascorbic acid was decreased by irradiation with higher dose. Although delay in irradiation caused less loss of ascorbic acid (8.5%) but showed greater metabolic changes as sprouting, weight loss, firmness, and sugars contents. Also, more increased delay in irradiation needed higher radiation doses for sprout inhibition.
