ON OPTIMAL INVESTMENT FOR A BEHAVIORAL INVESTOR IN MULTIPERIOD INCOMPLETE MARKET MODELS

We study the optimal investment problem for a behavioral investor in an incomplete discrete‐time multiperiod financial market model. For the first time in the literature, we provide easily verifiable and interpretable conditions for well‐posedness. Under two different sets of assumptions, we also establish the existence of optimal strategies.     

酪氨酸激酶抑制剂治疗非小细胞肺癌的临床应用

吉非替尼为一种选择性的EGFR一蛋白酪氨酸激酶抑制剂,能阻断酪氨酸蛋白激酶信号传导通路,从而促进肿瘤细胞凋亡。它是作为第一个用于肺癌治疗的分子靶向药物,在治疗非小细胞肺癌中拥有其自身的优越性在临床中取得了一定成效,但仍存在很多问题。本文针对吉非替尼靶向治疗非肺癌小细胞肺癌中的优点和所面临的问题进行阐述。     

人类副流感病毒F蛋白抗原性的信息学分析

依据报道的人类副流感病毒I型F蛋白氨基酸序列,通过SPOMA服务器、Signalp3.0服务器预测了F蛋白的二级结构和信号肽;通过TMHMM-2.0服务器预测了F蛋白的跨膜区;通过使用PROTSCALE服务器、SYFPEITHI服务器和Harvard的工具,综合分析得出F蛋白上第190-195和390-399区段可能为抗原肽段区域。该研究结果为副流感亚单位疫苗的研制奠定了基础。     

沈阳市再生水源热泵供暖技术的节能减排潜力

利用生命周期评价方法分析对比再生水源热泵和燃煤锅炉在原材料生产、机组生产、运输、热量生产及废弃物处理整生命周期过程的能源消耗及SO2、总悬浮颗粒物(TSP)排放。结果表明在生产1GJ热能的情况下,再生水源热泵比燃煤锅炉节能约1GJ,减排SO20.7kg,减排大气TSP 7.2kg。热量生产阶段是耗能及污染物排放的关键环节,超过99%的能源消耗和污染排放在这一环节产生。在供暖季节,如果沈阳市现有和规划污水处理厂的再生水应用再生水源热泵替代燃煤锅炉供暖,在每年的供暖期里可为沈阳市节能11×106GJ(折合标煤37.5×104t),减排SO275.9t,减排TSP 775.4t。     

The effect of the length of soaking time on trypsin inhibitor,crude protein and phosphorus contents of soybeans (Glycine max)

A study to determine the effect of soaking soybeans (Glycine max) at different periods of time on trypsin inhibitor, crude protein and phosphorus contents was carried out. The results showed that the length of soaking period had significant effect (P < 0.05) on trypsin inhibitor and crude protein contents. The activities of the trypsin inhibitor were 10% in roasted soybeans, 27.5% in raw and a range of 26.6% for those soaked in water for 24 h to 17.7% for soybeans soaked for 96 h or more, with a standard error of 6.56 on each of the values. The crude protein contents were 41.58% in raw, 31.43% in roasted and a range of 40.05–30.64% for those soaked in water for 24–120 h. The standard error on each value was 5.09%. On the other hand, length of soaking period had no significant effect on phosphorus content. It can be concluded from this that soaking soybeans in water can effectively remove the anti‐nutritional factors. While roasting is better, the use of fire wood may not be encouraged as it has caused a lot of deforestation with consequent occurrence of floods and hence food shortages. Such a good animal husbandry practice can help to improve the health of animals, which can in turn help to improve the health of the population.     

-learning agents in a Cournot oligopoly model

Q-learning is a reinforcement learning model from the field of artificial intelligence. We study the use of Q-learning for modeling the learning behavior of firms in repeated Cournot oligopoly games. Based on computer simulations, we show that Q-learning firms generally learn to collude with each other, although full collusion usually does not emerge. We also present some analytical results. These results provide insight into the underlying mechanism that causes collusive behavior to emerge. Q-learning is one of the few learning models available that can explain the emergence of collusive behavior in settings in which there is no punishment mechanism and no possibility for explicit communication between firms.     

Women’s Empowerment and Child Malnutrition: The Case of Mozambique

Using data from the 2011 Demographic and Health Survey in Mozambique this paper checks whether women empowerment has an impact on the nutritional status of children. We evaluate the degree of empowerment of women via multidimensional approaches, making a distinction between five domains: decision making, use of violence by husband/partner, attitude of the woman towards this use of violence, available information, material resources. Each domain includes several questions reflecting different aspects of empowerment. For each domain of empowerment, three different methods of aggregation are used: correspondence analysis, the so‐called Alkire and Foster methodology and the “fuzzy sets” approach. The impact of women empowerment on the nutritional status of children is analyzed via the MIMIC approach. No clear‐cut conclusion concerning the possible impact of women’s empowerment on the nutritional status of children could be drawn. But, ceteris paribus, the material wealth of the household, the educational level of the mother and her BMI are positively correlated with the nutritional status of children which is also higher when the child is female. Finally, there are important differences in the nutritional status of children between the various regions of Mozambique and this nutritional status is in most regions lower in rural areas.
