A Circular Economy Approach to Sustain the Souss River, Morocco, Ecosystem Services

This article discusses the role of the Souss river in disaster risk reduction, climate change adaptation and sustainable development through mainstreaming natural capital into macro-economic policies. The river course, rising from several headstreams in the high Atlas mountain and flowing westward for 180 km to the atlantic ocean is the beating heart of the Argan biosphere reserve. Its alluvial basin ensures the vital link between biodiversity and the population＇s utility functions for more than three million inhabitants. It is one of Morocco＇s most fertile regions where citrus fruits, vegetables, olives are grown beside an argan natural grove, and many of them are for export. Recent growing concern of local authorities tackles natural disasters and subsequent social issues associated to climate change, resource scarcities and flooding damages, especially after the 2014 flood events. This situation paved the way for local NGO incentives to embrace an ecological civilization approach for reconciliation with the Souss river. The local option adopted is to reverse the trend of intensive modem agriculture through a counterbalancing circular economy approach towards an agro-ecological producing pattern in order to sustain the river water balance.

Pigment characterization for the 2011 bloom in Qinhuangdao implicated "brown tide" events in China

A large-scale bloom occurred from May to June in 2011 in sea area near Qinhuangdao of the Bohai Sea, leading to huge damage of the scallop culture industry. Similar blooms have been observed in this region for three years. The causative species of the bloom, which dominated the phytoplankton community with the maximum cell density around 109 cell/L, could not be identified with morphological features due to the small cell size （-2 μm）. A pigment analytical method was then adopted to analyze the pigment profile of the phytoplankton samples collected from the blooming sea area. It was found that pico-sized （〈2 μm）, nano-sized （2-20 μm）, and bulk phytoplankton samples had similar pigment profile, representing the pigment signature of the bloom-causative species. The major pigments detected included 19-butanoyloxyfucoxanthin （But-fuco）, fucoxanthin （Fuco）, diadinoxanthin （Diad） and chlorophyll a （Chl a）, and high content of But-fuco was the most significant characteristics of the phytoplankton samples. Based on the pigment composition and content, the bloom-causative species could be tentatively identified as pelagophyte, ＂type 8＂ group of haptophyte, or silicoflagellate. Some unique features of the bloom, such as the extremely high cell density, small-sized and But-fuco containing cells, occurring in early summer, and the feeding-cessation effects on scallops, suggest it be a ＂brown tide＂ event similar to those reported in the east coast of the United States of America. The recurrent ＂brown tide＂ events and their dramatic impacts on the shellfish mariculture industry in QirLhuangdao need close attention in the coming years.

The Investigation of Executive Condition of Minority Regions＇ Special Education Policies： The Case of Du＇an Autonomous County

The unbalance development of education is a widespread problem around the world, and the most outstanding of it is the lag of the education development of minority regions. For the sake of developing the education of minority regions, the government adopted a lot of policies and measures, enacting special education policies is the important matter among them. The paper tries to take Du＇an autonomous county, Guangxi autonomous region as a case to explore the problems in the executive condition of minority regions＇ special education policies, and gives the suggestion for the government to accelerate the education development of minority regions.

The Impact of Water Pollution Announcement on Stock Returns in Taiwan Textile Industry

The soccer teams of the World Cup wear the jerseys manufactured by Taiwan Residents textile companies which are the contractors of such brand corporations as Nike and Adidas. Because Taiwan Residents textile companies suffer water pollution events, this study verifies the market reactions to the two announcements of water pollution events from 2014 to 2015. The two events are as follows： first, Greenpeace International enabled 38 scientists to announce the ban on fluoride in Madrid; second, Greenpeace International has detected fluoride residues from the water in remote mountainous areas of Europe and concluded that Taiwan Residents jerseys composed of fluoride pollute the rivers or snows. The findings of the research indicate that the announcement of the ban on fluoride induces negative abnormal returns because fluoride is the main materials for Taiwan Residents jerseys. Most importantly, the announcement of the water pollution in Europe from Taiwan Residents manufactured jerseys induces negative abnormal returns. Both of the two events enable the stock investors scared about the decrease of future profit and market share for Taiwan Residents textile corporations. Consequently, investors sell the stocks of these corporations, inducing the negative abnormal returns during the announcement of water pollution of Taiwan Residents jerseys. Water polluted issues are critical of firm values.

Gender, Poverty and Climate Change in Nigeria

The purpose of this paper is to examine the impact of climate change on gender and poverty in Nigeria. The paper relies mainly on secondary data generated by private individuals, government and non-government bodies. From these sources, the paper reveals that climate change has resulted in higher temperature increase frequency on extreme weather events in the country, such as storms or record drought resulting in the dislocation of agricultural areas and its consequence food shortage. Women are the hardest hit because they produce food and do not have control over land to make most communities vulnerable to flooding as seen in Lokoja, Bauchi and Kaduna among others in Nigeria. Flooding has increased the frequency of vector-borne diseases such as malaria, dysentery, typhoid, cholera, etc.. Women who clean the mess left behind after the flood are mostly affected. It is also revealed that climate change has resulted in great economic losses, with most of the losses to be in agricultural production, the engine of growth and the mainstay of the economy. Finally, the paper suggests measures such as reduction in deforestation by provision of alternative source of energy and environmental friendly industrial activities will help reduce the rate of discharge of carbon-dioxide into the atmosphere.

Progress billing method of accounting for long-term construction contracts

This article questions the reliability of the amount of revenue recognized in the percentage of completion （POC） method of revenue recognition in construction industry and recommends a new method based on the progress billing which is more reliable. The most commonly used method of revenue recognition in the construction industry is the percentage of completion method （POC）, where the revenue is recognized on the basis of the percentage of work completed. The calculation of percentage of work completed is made on the basis of the cost incurred for the contract work during the financial period and the cost required for completion of the work as estimated by the contractor. Here, the acceptance of the product by the buyer （contractee） is not involved in recognizing the revenue. The reliability of the amount of revenue and its collectability can be assured only when the buyer accepts the product. The approval of the progress bill by the contractee is needed to assure the reliability and collectability and it must be the event that triggers the recognition of revenue.
