Metabasic Dyke Swarms in a High-Grade Metamorphic Terrane——A Case Study in the Taipingzhai-Jinchangyu Area,Eastern Hebei Province

Geological and petrological studies indicate that three phases of metabasic dykes are present in theTaipingzhai-Jinchangyu area within the high-grade metamorphic terrane of eastern Hebei. Garnet andhornblende in metabasic dykes of the second and third phases occur separately, forming two mineral aggregateareas gl+cpx+pl±hy and hb+cpx+pl-hy. P_(H_2O) in the rocks appears to be the main factor controlling theformation of the two aggregate areas. Both were formed simultaneously at the same metamorphic temperature. The second-phase basic dykes underwent metamorphism of pyroxene-granulite facies at a temperature ofsome 825C: later the dykes, together with the third-phase basic dykes experienced metamorphism ofamphibole-granulite facies at a temperature of about 750C under pressure of 0.9GPa.

Taking the Han's Cattle and Lamb Fattening Cooperative Organization in Gonghe County of Qinghai Province as an example,the geographic situation,establishment process and operation situation of the cooperative organization are expounded.And then the social effect of returning migrant workers who start their own business is analyzed.In the first place,starting their own business has promoted the rapid development of economy at county level;in the second place,it has promoted the adjustment of agricultural structure;in the third place,it is conducive to reallocating resources.The problems in the development of Han's Cattle and Lamb Fattening Cooperative Organization are analyzed from four aspects covering weakening of village' cadres,multiple ethnic groups,difficulties in expanding scale cooperation and inadequate funds.Three countermeasures which are conducive to creating favorable external environment for migrant workers to start their own businesses,takes the ethnic factors into consideration and implements scale operation,so as to solve the new problems in the process of developing rural farmers' cooperative organization and provide the evidence for formulating relevant policies.

Discussion on the Challenges Surrounding Anti-microbial Resistance,Using Relevant Case-study Examples

The advent of antimicrobial drugs has made a huge contribution to human society,but their commodity nature has given rise to behaviors such as abuse and overuse,leading to the emergence of resistance to antimicrobial drugs and other hazards.Nowadays,the structure of interests formed by various stakeholders in the market circulation of antimicrobial agents has become unbalanced,and government intervention as a breakthrough still faces many challenges.This paper discusses the AMR challenges of government intervention under the interest structure in the context of case studies in the Global North and the Global South areas from the point of view of human health in terms of stagnant R&D processes for novel antimicrobial drugs,a profit-oriented neoliberal atmosphere that mismatches production trends of antimicrobial drugs with market demand,the prevalence of private institutions lacking effective regulation,incomplete government interventions,and the difficulty of pursuing the WHO strategic plan on antimicrobial resistance,etc.

Low selenium and reduced cognitive function in a cohort elderly study

Cognitive function in the elderly is affected by various environmental,social,and individual factors.Studies show that chemical trace elements are closely related to cognitive function.As a protective factor,selenium promotes cognition in the elderly.However,study results into the effects of selenium on cognition have varied.By eliminating unstable environmental and other related factors,the present study selected elderly individuals from rural areas of the Shandong province to verify whether low selenium exposure is a risk factor for decreased cognitive function.Results demonstrated that age,sex,education,occupation,hypertension,stroke,and body selenium levels were factors affecting cognitive function in the elderly,and that selenium was an important protective factor.Moreover,results supported the hypothesis that a lifelong low selenium level is associated with low cognitive function.

A Study of the Mechanism for Distribution of Benefits Based on Vertical Coordination in Agriculture

Currently,the mechanism for distribution of benefits based on vertical coordination in the area of agricultural products can be divided into some types such as market price regulation,contract agreement,and dividend distribution according to trading volume or shares,and internal profit of enterprise. There are differences in operating characteristics,advantages and adaptation between different mechanisms. And contract agreement can be subdivided into guaranteed price,market protection price,market protection price + preferential services,and market protection price + secondary rebates. Taking the citrus processing industry in Zhongxian County for example,it is recommended to learn from the Taiwan experience to strengthen the linking between citrus cooperatives,and develop the order mode as well as the " market protection price + preferential services" mechanism for distribution of benefits.

The Governance of Rural Tourism Destination under the Eco-bank Model-A Case Study of Jukou Township in Fujian Province

Rural tourism is an important means of comprehensively promoting the rural revitalisation of industry andpractising the concept of“two mountains theory”.Rural tourism transforms the resource advantages of rural areasinto economic advantages,but its development entails problems such as the unfair distribution of benefits,uncleardistribution mechanisms,and the non-standardised compensation of benefits.Therefore,finding a mode of governance of rural tourism that can effectively achieve sustainable development is an urgent issue that warrants attention.Taking Jukou Township in Fujian Province as a case,this study constructs a logical framework linking theEco-bank model and rural tourism governance and reveals the practicality and sustainability of rural tourism governance under the Eco-bank model.The study shows the following.(1)As a kind of innovative mechanism forachieving the transformation of resource value through the participation of multiple subjects,the Eco-bank modelsolves the development dilemma of rural tourism through the integration of decentralised resource managementrights,the establishment of property rights constraints and supervision mechanisms for the coordination of stakeholder interests,and the linkage and development of internal and external resources of the countryside.(2)JukouTownship has built a resource operation platform for“ancient house Eco-bank”based on ancient house resourcesand ecological tourism resources.The construction of a rural governance mechanism that combines village collectives,new township elites,villagers,high-end art operation units,and multiple institutional governance entities effectively converts idle ancient houses and high-quality ecological tourism resources into assets and funds to promote the development and growth of the rural collective economy while effectively promoting the stable and sustainable development of the cultural tourism industry in Jukou Township.
