Urban Market-Gardening in Parakou (Republic of Benin): Spatial Dynamics, Food Security, Protection of the Environment and Creation of Employments

Nowadays, African cities are subjected to upsets which result from the extraordinary growth of urban populations. The growth of the population of cities has induced some changes in the structure of the activity of those cities. Agriculture which was formerly confined to the countryside henceforth develops in the urban area and occupies a preponderant place as a strategy of survival, of insertion and of food supplying of the city-dwellers. It has become an activity integrated to the urban tissue through systems of occupying and exploitation of land in the urban area. Population growth (4.81%) between 2002 and 2013 is a critical poverty rate (65%) of the population of Parakou city, entailing a misery perceptible in all its social and economic dimensions. The market-gardening activity has integrated itself to the urban tissue. The objective of this study is to understand how urban agriculture through market-gardening can be a solution for rural farmers who have moved to Parakou city. In this study, documentary research, interviews and field observation are used for data collection. The main results to be signaled among others are: evolution and status of the market-gardening areas in Parakou, the reduction of food insecurity with the permanent availability in quantity and in quality of market-gardening products accessible to the population: the protection of the environment through the drainage of the urban area and the preservation of the diversity of vegetables;the increase of the income of the households of the farmers and the creation of employments.

Price linkage between Chinese and international nonferrous metals commodity markets based on VAR-DCC-GARCH models

Using VAR-DCC-GARCH model,the literature on commodity price was extended by exploring the co-movement between Chinese nonferrous metal prices and global nonferrous metal prices represented by the nonferrous metal prices from London Metal Exchange(LME).The results show that LME nonferrous metals prices still have a greater impact on Chinese nonferrous metals prices.However,the impact of Chinese nonferrous metals prices on LME nonferrous metals prices is still weak except for lead price.The co-movement of nonferrous metal prices between LME and China presents hysteretic nature,and it lasts for 7-8trading days.Furthermore,the co-movement between LME nonferrous metals prices and Chinese nonferrous metals prices has the characteristics of time-varying,and the correlation of lead prices between LME and China is the more stable than all other nonferrous metals prices.

Safety and Diagnostic Image Quality of Ultravist^®in an Unselected Sub-Set of Chinese Patients: Data Analyses from a Previous Post Marketing Surveillance

Background: Iopromide (Ultravist&reg) has been shown to be a very safe CM agent in previous post-marketing surveillance studies on Western and Asian populations. Our study aimed to analyse data pertaining to the safety, tolerability and diagnostic image quality of Iopromide in an unselected sub-set of the Chinese population. Methods: we analysed data for Chinese ambulatory and in-patients who received Iopromide for an imaging procedure (in accordance with the local package insert and routine clinical practice), as part of an international post-marketing surveillance study. Use of premedication was at the discretion of the attending physician. Patient demographics, clinical history, type of examination, contrast quality and tolerability, including pre-specified adverse drug reactions, were recorded. All statistical analyses were descriptive. Results: case report forms for 20,000 Chinese patients (61.3% men) were analysed, of whom 153 patients (0.77%) had risk factors for idiosyncratic contrast media reactions (at-risk group). Use of premedication, most commonly corticosteroids, was recorded for 5658 patients (28.3%) and 86 at-risk patients (56.2% of the at-risk group), respectively. The mean (±standard deviation) dose of iodine administered was 29 ± 5.5 g. During the physician’s evaluation of image parameters, contrast quality was considered to be “good” (64.7%) or “excellent” (29.3%) in the majority of patients. 571 patients (2.9%) experienced at least one adverse drug reaction [most frequently nausea (0.70%) and dysgeusia (0.62%)], which were typically transient and of mild intensity. Two serious adverse drug reactions were reported [edema (n = 1), decreased blood pressure and dyspnea (n = 1)]. The incidence of adverse drug reactions was increased in the at-risk group versus the overall patient population, and tended to reduce with premedication (mainly corticosteroids). Conclusions: Iopromide was well tolerated and proved to be an efficient contrast agent in a large, non-selected sub-set of Chinese patients undergoing different types of diagnostic imaging procedures.

市场转型期的农村社会保障制度建设:进展与偏差

自1980年代中期开始我国对农村养老、医疗、社会救助等主要社会保障项目进行了一些改革的尝试和探索。这一时期的改革在制度本身的建设、制度环境的建设及立法保障的建设等方面都取得了一定的进展。但由于多种原因,总的来说,农村社会保障改革的步伐不大,制度化程度还不高,家庭保障仍是农村社会保障的基本模式,保障功能差且比较脆弱。改革以来农村社会保障制度建设的偏差主要表现在对土地的保障功能估计过高,对农村社会保障制度建设缺乏明确的目标定位和稳定的推进措施,政府本该履行的角色不到位等。

Research on the Model of Long Term Generation Planning in Power Market Reform

With the deepening of China’s power market, bilateral transactions will continue to grow in large scale. The release of bilateral transactions locked more regulatory resources of the power grid, will directly affect the operation mode of the unit and the implementation of planned electricity.

Chinese Stock Price and Volatility Predictions with Multiple Technical Indicators

While a large number of studies have been reported in the literature with reference to the use of Regression model and Artificial Neural Network (ANN) models in predicting stock prices in western countries, the Chinese stock market is much less studied. Note that the latter is growing rapidly, will overtake USA one in 20 - 30 years time and thus be-comes a very important place for investors worldwide. In this paper, an attempt is made at predicting the Shanghai Composite Index returns and price volatility, on a daily and weekly basis. In the paper, two different types of prediction models, namely the Regression and Neural Network models are used for the prediction task and multiple technical indicators are included in the models as inputs. The performances of the two models are compared and evaluated in terms of di- rectional accuracy. Their performances are also rigorously compared in terms of economic criteria like annualized return rate (ARR) from simulated trading. In this paper, both trading with and without short selling has been consid- ered, and the results show in most cases, trading with short selling leads to higher profits. Also, both the cases with and without commission costs are discussed to show the effects of commission costs when the trading systems are in actual use.
