Environmental Analysis of Packaging for Soft Drinks Using the Life Cycle Assessment Methodology

The knowledge of a product＇s life cycle is the first step on the search of sustainable development. The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.     

农网改造升级工程接地施工若干质量问题的防控探讨

当前我国已经将决战脱贫攻坚、决胜全面建成小康社会作为主要的战略目标,为了实现这一目标,实现脱贫攻坚,电力保障是一个非常重要的因素。近年来我国全面推进农网改造升级工程。农网改造工程的接地施工质量的重要性毋庸置疑,但是农网改造工程的特殊性又使得接地质量的判断变得不好把握,本文从农网改造工程接地质量现状、防控措施等方面进行探讨。     

亚太区域贸易协定的经济增长效应*——基于RTAs数量与质量的对比研究

21世纪以来，亚太地区区域贸易协定（RTA）签署的数量激增，学术界理论与现实出现悖论，引发学者思考各国热衷于建立RTAs背后的原因并探索新的研究方法。本文首次从RTAs数量和质量的影响效应哪个更为重要的视角，将发达国家和发展中国家进行对比分析，深入探究发达国家在新时期推进新一代贸易协定规则的原因。通过比对RTA协议的每一条条款，测算出涉及传统WTO+和新一代WTO-X领域的条款覆盖率和法定承诺率指标来衡量RTA的质量，实证分析得出，签署高质量的区域贸易协定能更有效地推动亚太地区的经济增长和人民福利水平的提高，该影响效应在发达国家中更为明显，而发展中国家受限于执行能力在新一代规则下签订RTA对经济增长的作用不显著。     

Some Variants of Constrained Estimation in Finite Population Sampling

This is a review article that unifies several important examples using constrained optimisation techniques. The basic tools are three simple mathematical optimisation results subject to certain constraints. Applications include calibration, benchmarking in small area estimation and imputation. A final illustration is constrained optimisation under a general divergence loss.     

Ramshackle farmhouses,useless old stables,or irreplaceable cultural heritage? Local inhabitants’ perspectives on future uses of the Walser built heritage

Social and economic developments in rural regions call for a discussion of strategies of dealing with redundant traditional buildings. Using a social science approach, our study examines how the local population in two rural regions perceives the built heritage and which factors are underlying these perceptions. People’s attitudes towards maintaining the cultural heritage vary considerably and are partly influenced by the socio-cultural and economic context of the region. The present article discusses some of the core regional socio-cultural influences on attitudes towards the rural built heritage. Following from qualitative interviews, the article concludes that the scale of perception of the built heritage is related to the “liveliness” of the local culture: The more original and distinctive the local culture is, and the more the local economy is still based on agriculture, the wider the scale of perception of the traditional cultural landscape and built heritage. In a region with local traditions that are alive and followed in everyday life, and a local economy that is mainly based on agriculture, the entire settlement structure is perceived as cultural heritage. In such areas, alternative uses should be found for redundant buildings. In contrast, in regions where the culture is less visible and alive nowadays and where the local economy has changed, people tend to perceive single buildings as representing their cultural heritage, and they often wish to preserve and conserve such remaining houses, barns and stables. In the study, we show that from a social science point of view, there is no universal perception of the maintenance of built cultural heritage. Rather, we see different views and opinions that are important to consider when it comes to developing heritage protection strategies together with public authorities.

Will FinTech make regional banks superfluous for small firm finance? Observations from soft information-based lending in Germany

Regional banks have a competitive advantage in that short distances to clients enable the use of soft information for superior lending decisions. If the ambition of FinTech start-ups to create superior screening and monitoring technologies materialises, this advantage would be diminished and regional banks would become superfluous for small firm finance. To explore this claim, the paper in hand analyses qualitative empirical data about the lending processes and rating system use of regional German savings banks. In essence, the results from participant observation and interviews clarify the importance of “real” soft information for critical lending decisions. The context specificity and limited verifiability of “real” soft information hamper it from being hardened through the use of rating systems and other bank-ICT. Though FinTech's scoring technologies may overcome the first limitation, it appears likely that in the course of scoring development “real” soft information will be systematically crowded out due to the manipulation problem. The paper expects improved access to finance for SMEs if FinTech solutions overcome both limitations of “real” soft information use, or if peer-to-peer lending and regional banks coexist. Deteriorated access to finance is expected if FinTech companies displace the relationship banking of regional banks due to enhanced competition, without preserving the advantages of “real” soft information with superior screening and monitoring technologies. The paper concludes with recommendations on how to prevent deteriorated access to finance for small firms by promoting fair competition and FinTech innovations.     

别让IT运维成为中小企业迈向国际化的“包袱”

随着中国改革开放的不断深入,中国加入WTO,国内中小企业如雨后春笋般的发展起来,甚至已经将公司开到了国外,为新中国的经济腾飞做出了不可磨灭的贡献,期间IT系统在规范管理、提升工作效率方面起到了应用的作用。但随着企业规模的不断扩大,分公司越来越多,地域间隔越来越远,IT系统运维正变得空前困难。鉴于此,本文将着重介绍如何利用新技术降低IT运维成本,提升运维效率。
