Memory and resilience: A two-pronged approach to natural spaces in Colombia’s transition to a peaceful society

The analysis of spontaneous environmental initiatives undertaken by individuals and communities in cases of conflicts has led to a growing research field in social science, according to which the community-based stewardship of nature seems to conduce to the resilience of co-evolved social-ecological systems. In Colombia, where no such research exists so far, the conflict which officially ended in November 2016 has led to massive internal migration due to forced displacement, as well as to widespread degradation of the environment. Based on evidence provided by case studies of top-down and bottom-up living memorials and urban agriculture initiatives, the article explores the potential of urban greening in the process of memorialisation and in generating new social cohesion, as well as better living conditions in urban areas. It analyses cases both where the conflict has taken place and in the cities where refugees have settled, in order to explore avenues for public policies in post conflict Colombia. The author concludes that greening initiatives offer manifold, so far overlooked, opportunities to restoring social and ecological resilience in urban areas and thus contribute to a lasting peace in Colombia.

论高校图书馆读者公德素养的培育

读者公德素养培育是高校图书馆读者教育的重要组成部分.对比当前图书馆发展与读者公德素养现状得出,读者公德素养培育有其紧迫性和长期性。读者公德素养培育既要满足时代发展的要求,也要满足个人发展的要求,只有克服其培育内容的单一化,注重读者＂礼＂、＂爱＂、＂责＂、＂诚＂几种品质的培养,利用教育引导、榜样示范与制度约束相结合的方式,才能取得比较理想的效果。

Suitability of Multi-Agent Simulations to study irrigated system viability: application to case studies in the Senegal River Valley

It is assumed that Agent-Based Modeling is a useful technique for water management issues. In particular, it may provide a suitable framework for representing irrigated systems. The objective of this paper is to demonstrate its potential for a specific use: research on irrigated systems’ viability in the Senegal River Valley. The main assumption to be verified is that Multi-Agent Systems constitute a suitable architecture to study theoretically irrigated systems’ viability using simulations. By using Multi-Agent Systems, virtual irrigated systems can be designed that might then be used as virtual laboratories. These virtual labs constitute an alternative when real labs cannot exist for some reason.

In this paper we report on experiments we have conducted using such virtual labs for exploring an Agent-Based Model through the simulation of scenarios. A scenario is defined as a triplet: an environment, a set of individual rules, a set of collective rules. It is evaluated according to the longevity of the irrigated system. An index is defined, based on the ratio of long-enduring simulations among a set of repetitions of a given scenario. Even if simulation results display significant diversity for a given scenario due to random factors in the processes simulated, the ratio of long-enduring simulations is repeatable. This entails to explore the overall behavior of the virtual irrigated system and to build theories concerning the viability of Senegalese irrigated systems. An example is given showing the need for strong coherence for a given environment among individual rules and collective rules.     

Water availability affects nectar sugar production and insect visitation of the cup plant Silphium perfoliatum L. (Asteraceae)

The perennial cup plant (Silphium perfoliatum L.) is considered as an alternative feedstock to maize for biogas plants. Due to its ecological advantages of an extensive management and function as food resource for pollinators, it can be grown in Ecological Focus Areas (EFAs) since 2018. However, studies at the Julius Kühn-Institute in Braunschweig (Germany) showed that the assumed advantage of the cup plant of a high drought tolerance could not be confirmed regarding aspects of crop production and yield. We complemented this experiment by assessing how different soil moisture conditions affect the production of floral resources and insect visitation. In 2014, we sampled three irrigated and three rainfed plots of the cup plant. We quantified the nectar volume and sugar mass per inflorescence, the number of inflorescences per plant and calculated the total nectar sugar production. We further counted insect visitation on the inflorescences. Due to reduced numbers of inflorescences per plant and an earlier harvest, the estimated nectar sugar production was 58 kg/ha regarding irrigated and 20 kg/ha regarding rainfed plots. Honeybee visitation per inflorescence was about twice as high in the irrigated plots. Furthermore, the early harvest is a disadvantage for wild pollinators with a late activity period.     

基于企业性质的社会责任履责动机差异及政策含义

从企业性质的角度出发,分别就履行社会责任的经济动机（价值增值驱动和管理层面对的代理问题驱动）与非经济动机（道德伦理驱动和政治驱动）下,国有与私营企业在履行社会责任动机方面的差异进行初步分析,发现企业的性质、目标决定了我国国有企业比私营企业面临更多的代理问题,私营企业相对国有企业而言更有追逐价值增值而履行社会责任的经济动机,也更加受到寻求政府政治保护等政治因素的驱动。政府应从企业履责动机出发,深刻认识政策法规对企业社会责任的促进作用;通过加强政策导向,直接或者间接促进国有企业和私营企业践行社会责任。     

西部退耕还林工程社会影响评价——以会泽县、清镇市为例

从毁林开荒到退耕还林是对单纯追求物质文明的经济增长模式的否定，符合社会发展方向，是我国实施可持续发展战略的必然选择。西部退耕还林工程给工程实施区带来了方方面面的影响，工程的有效性和持续性受到各种因素的挑战，全面评价工程实施所产生的现实影响是提高决策科学性的必要前提。论文根据工程的特点建立西部退耕还林工程社会影响评价指标体系，通过深入调查研究取得评价的基础材料，以会泽县和清镇市为例，用定性定量相结合的方法从生态、社会和经济效益3方面对退耕还林所产生的影响进行系统分析与评价，在探明实施中制约工程有效性和持续性的社会变量的基础上，提出工程可持续发展的若干对策。     

Urban Public Space Development in Harbin Driven by Music Culture Intervention

"Social event driving" has become a way to promote urban development, create urban public spaces and create a city image. As one of the important big cities in northeastern China, Harbin enjoys the reputation of "The Music City", and its public space development is inextricably linked with the driving of music culture. This paper started with the analysis of the correlation between the development of urban public spaces and the development of music culture in Harbin, and studied the influence and driving role of music culture on the construction and development of urban public spaces.
