瑞典环境法法典化对我国的启示

在《瑞典环境法典》编纂之前,其《环境保护法》存在诸多问题,如:指导性不强、威慑力不足、过于抽象、各环境法律法规之间存在重叠与冲突等,为了使环境领域的立法实现体系化并促进可持续发展,瑞典开始编纂《环境法典》。《瑞典环境法典》采取适度法典化的编纂模式,在编纂过程中注重本土化和国际化的有效结合,最后形成"以法典法为主,辅之以单行法"的环境法律体系。通过对瑞典环境法法典化的特点及原因进行深入研究,并结合我国环境保护领域的立法现状可以得知,我国环境立法应采取适度法典化的立法模式:编纂环境法典应分阶段进行,而不是一蹴而就;应以形式化法律汇编作为起点,逐步向实质性法典编纂迈进。此外,还要加强环境法典编纂的理论研究为法典编纂提供充足的理论支撑。     

Governing sexual behaviour through humanitarian codes of conduct

Since 2001, there has been a growing consensus that sexual exploitation and abuse of intended beneficiaries by humanitarian workers is a real and widespread problem that requires governance. Codes of conduct have been promoted as a key mechanism for governing the sexual behaviour of humanitarian workers and, ultimately, preventing sexual exploitation and abuse (PSEA). This article presents a systematic study of PSEA codes of conduct adopted by humanitarian non‐governmental organisations (NGOs) and how they govern the sexual behaviour of humanitarian workers. It draws on Foucault's analytics of governance and speech act theory to examine the findings of a survey of references to codes of conduct made on the websites of 100 humanitarian NGOs, and to analyse some features of the organisation‐specific PSEA codes identified.

Virtues and humanitarian ethics

This paper analyses the contribution of virtue ethics, the study of good character traits, to the humanitarian context. It argues that a virtue ethics perspective paints a realistic picture of the use of ethical standards in morally complex circumstances. Virtuous relief workers can employ standards in their thinking, but they are also committed to professional excellence that goes beyond any formal code. The concept of virtue ethics places a stress on moral development, which can be facilitated by role models that impart modest and feasible ideals. However, virtue ethics cannot provide simple guidelines on how to resolve difficult situations. It is possible that two virtuous persons can disagree on what should be done in a particular instance. In addition, a virtue ethics perspective emphasises the need for both individuals and organisations to discuss the actual purpose of relief work in order to pinpoint the virtues of a good relief professional.

Scientists as Stakeholders in Conservation of Hydrothermal Vents

Abstract: Hydrothermal vents are deep‐sea ecosystems that are almost exclusively known and explored by scientists rather than the general public. Continuing scientific discoveries arising from study of hydrothermal vents are concommitant with the increased number of scientific cruises visiting and sampling vent ecosystems. Through a bibliometric analysis, we assessed the scientific value of hydrothermal vents relative to two of the most well‐studied marine ecosystems, coral reefs and seagrass beds. Scientific literature on hydrothermal vents is abundant, of high impact, international, and interdisciplinary and is comparable in these regards with literature on coral reefs and seagrass beds. Scientists may affect hydrothermal vents because their activities are intense and spatially and temporally concentrated in these small systems. The potential for undesirable effects from scientific enterprise motivated the creation of a code of conduct for environmentally and scientifically benign use of hydrothermal vents for research. We surveyed scientists worldwide engaged in deep‐sea research and found that scientists were aware of the code of conduct and thought it was relevant to conservation, but they did not feel informed or confident about the respect other researchers have for the code. Although this code may serve as a reminder of scientists’ environmental responsibilities, conservation of particular vents (e.g., closures to human activity, specific human management) may effectively ensure sustainable use of vent ecosystems for all stakeholders.

Role of glycine on sulfuric acid-ammonia clusters formation: Transporter or participator

Glycine(Gly) is ubiquitous in the atmosphere and plays a vital role in new particle formation(NPF).However,the potential mechanism of its on sulfuric acid(SA)-ammonia(A)clusters formation under various atmospheric conditions is still ambiguous.Herein,a(Gly)_x·(SA)_y·(A)_z(z≤x+y≤3) multicomponent system was investigated by using density functional theory(DFT) combined with Atmospheric Cluster Dynamics Code(ACDC) at different temperatures and precursor concentrations.The results show that Gly,with one carboxyl(-COOH) and one amine(-NH_2) group,can interact strongly with SA and A in two directions through hydrogen bonds or proton transfer.Within the relevant range of atmospheric concentrations,Gly can enhance the formation rate of SA-A-based clusters,especially at low temperature,low [SA],and median [A].The enhancement(R) of Gly on NPF can be up to 340 at T=218.15 K,[SA]=10~4,[A]=10~9,and [Gly]=10~7 molecules/cm~3.In addition,the main growth paths of clusters show that Gly molecules participate into cluster formation in the initial stage and eventually leave the cluster by evaporation in subsequent cluster growth at low [Gly],it acts as an important "transporter" to connect the smaller and larger cluster.With the increase of [Gly],it acts as a "participator" directly participating in NPF.     

确定压力容器安全系数原则

压力容器安全系数与材料参数紧密相关,确定材料许用应力值时,需要同时考虑材料抗拉强度和屈服强度更为合理;奥氏体不锈钢材料具有非常好的应变强化能力和韧性,为充分发挥奥氏体不锈钢材料优良性能,选取奥氏体不锈钢材料许用应力值时,需要特殊考虑。压力容器安全系数的选取建立在经验基础上,在保障压力容器安全性前提条件下,为节省材料和降低成本,随着理论研究深入和科学实验的进步,压力容器安全系数有所降低,这是科学设计和实用成功经验结合的结果。
