试论基础四国在后哥本哈根气候谈判中的立场和作用

基础四国是由中国、印度、巴西和南非四个主要发展中国家组成的气候谈判集团,鉴于其成员在发展中国家和世界上的影响力,该集团在国际气候谈判中备受关注。在构建2012年后国际气候机制的谈判中,基础四国的立场表现出了很高的协调性,但也存在一定的差异。总体而言,基础四国的出现和协调行动推动了国际气候谈判在公约框架下展开,有利于后京都气候安排的达成,但也可能促使国际气候谈判集团,特别是G77加中国的分化和重新组合。基础四国气候谈判集团出现时间尚短,其最终能够在构建后京都气候机制中发挥何种作用将取决于基础四国在应对气候变化中如何对待联合国渠道与其他渠道的关系、敦促发达国家减排的决心和能力以及是否能够保持G77加中国内部的团结性等。     

Novel O‐propyl,S‐propyl,and N‐propyl substituted 1,4‐naphthoquinones and 1,4‐anthraquinones as potential fingermark development reagents for porous surfaces

Lawsone is a 2‐substituted‐1,4‐naphthoquinone derivative, which has been proposed as an alternative to the reagents currently used for fingermark detection on porous surfaces. 2‐substituted‐anthraquinones, which contain an additional conjugated benzene ring, have a similar chemical structure to that of lawsone. In this study, a new series of 2‐substituted‐1,4‐naphthoquinones and 2‐substituted‐1,4‐anthraquinones were synthesized and completely characterized by¹H NMR,¹³C NMR, IR, and HPLC‐TOF/MS analyses. All newly synthesized 2‐substituted‐1,4‐quinones were investigated for their ability to develop latent fingermarks on porous surfaces, and this ability was compared with that of lawsone. Each fingermark developed was graded using an established method; thus, quantitative data were attributed to each fingermark. It has been demonstrated that the 1,4 ‐ quinones react with amino acids present in latent fingermarks on selected paper surfaces to produce faint yellow‐orange impressions, which exhibit strong photoluminescence when illuminated with a forensic light source at 440 nm and observed through a red filter. None of the compounds caused background darkening. The results obtained were generally similar to those of lawsone, however, 8‐dibromo‐2‐(propylamino)naphthalene‐1,4‐dione and 5,8‐dibromo‐2‐(propylthio)naphthalene‐1,4‐dione yielded better results for copier paper and colored (blue) copier paper used in this analysis. To the best of our knowledge, this is the first study to examine the role of 1,4‐anthraquinone derivatives as potential fingermark development reagents. The results indicate that 1,4‐quinones have a potential to be used as reagents for enhancement of latent fingermarks.     

The COLLECTORS ranking scale for ‘at‐scene’ digital device triage

As digital evidence now features prominently in many criminal investigations, such large volumes of requests for the forensic examination of devices has led to well publicized backlogs and delays. In an effort to cope, triage policies are frequently implemented in order to reduce the number of digital devices which are seized unnecessarily. Often first responders are tasked with performing triage at scene in order to decide whether any identified devices should be seized and submitted for forensic examination. In some cases, this is done with the assistance of software which allows device content to be “previewed”; however, in some cases, a first responder will triage devices using their judgment and experience alone, absent of knowledge of the devices content, referred to as “decision‐based device triage” (DBDT). This work provides a discussion of the challenges first responders face when carrying out DBDT at scene. In response, the COLLECTORS ranking scale is proposed to help first responders carry out DBDT and to formalize this process in an effort to support quality control of this practice. The COLLECTORS ranking scale consists of 10 categories which first responders should rank a given device against. Each devices cumulative score should be queried against the defined “seizure thresholds” which offer support to first responders in assessing when to seize a device. To offer clarify, an example use‐case involving the COLLECTORS ranking scale is included, highlighting its application when faced with multiple digital devices at scene.     

HUMAN TISSUE LEGISLATION AND MEDICAL PRACTICE: A BENEFIT OR A BURDEN?

The scandals surrounding organ removal and retention throughout the United Kingdom provoked several Inquiries and ultimately led to law reform. Although the medical professions were well represented at the Inquiries, little was heard of the voices of those at the 'coal face'. In this scoping study, funded by the Wellcome Trust, we interviewed a number of doctors and others engaged in the uses of human tissue and organs to explore their hopes, concerns and fears about the role of the law in their practices. We found that those involved in transplantation were more aware of, and more actively involve with, the law, whereas others, such as pathologists, had less direct engagement with the law. Most of those we interviewed expressed the hope that law reform would provide much-needed clarity. Although some expressed concern that the law might be over-intrusive, most felt that the placing of authority firmly in the hands of the person him or her self to decide what should happen to their bodies was to be welcomed.     

Visualization of latent fingerprints using fluorescence lifetime imaging on paper emitting strong fluorescence

Latent fingerprints were successfully visualized using fluorescence lifetime imaging (FLIM) on paper which emits strong fluorescence with a lifetime close to that of fingerprints and thus from which it is difficult for time-resolved spectroscopy to visualize fingerprints. Latent fingerprint samples on paper were excited using a 450 nm or 532 nm nanosecond pulsed-laser, and time-resolved fluorescence images were obtained at a delay time of 6–16 ns in intervals of 1 ns, to the excitation pulse. The excitation beam was expanded using a lens, and the fluorescence from the fingerprints was captured using an intensified CCD camera. Because of the large fluorescence intensity of the background paper of approximately two to four orders of magnitude larger than that of the fingerprint, the fingerprint was not visualized on each fluorescence image by time-resolved spectroscopy. However, the fingerprint was visualized in a FLIM image constructed using a series of the fluorescence images for the case with the fluorescence intensity of the background paper being four orders of magnitude larger than that of the fingerprint. The difference in fluorescence lifetime in the FLIM image of the visualized fingerprint and background paper was in the order of 0.1 ns, which was an order of magnitude smaller than the inherent fluorescence lifetime of a few nanoseconds for the fingerprints and paper. It was demonstrated that, at a background fluorescence intensity with a certain order of magnitude larger than that of fingerprints, FLIM has the potential to visualize latent fingerprints which cannot be visualized by time-resolved spectroscopy.     

Attitudes towards sex offenders regarding competency,liability, voluntariness of offence,and disposal: the influence of being classified as having a learning disability

Abstract

The principal aim of this study was to investigate whether attitudes towards judicial competency, legal liability, voluntariness of offence and judicial disposal options were influenced by known classification of an offender as learning disabled compared to an offender with a suggested intellectual disability, but not formally classified. Subsidiary aims were to explore participant attitudes based upon group membership and parental status. The sample consisted of 101 participants (69 undergraduate nursing students and 32 from the general population). Participants were requested to complete a questionnaire assessing their attitudes within the aforementioned domains and towards ascribed levels of victim parental responsibility. Fifty participants completed a questionnaire designed for the purpose of the study where the offence scenario depicted made reference to the offender having a formal classification of learning disability. Fifty-one participants completed the same questionnaire where an intellectual disability was suggested but not formally stated in the form of classification. Results indicated that classification did significantly influence attitudes in most domains irrespective of group. The nursing group attributed greater levels of competency to the offenders depicted. No interactions between variables were observed. The reasons for and implications of these findings, limitations and recommendations for future research are explored.     

Why were So Many Social Scientists Wrong about the Green Revolution? Learning from Bangladesh

Most social scientists once took a negative view of the socio-economic consequences of the Green Revolution. Events have since proved them wrong. Using Bangladesh as an example, we offer three reasons why social scientists were mistaken. One is the focus on village studies at the expense of nationally representative surveys. Another is insufficient appreciation of the technical limits of the new rice technology. The third is a misleading model of agrarian change. The inability of village studies to validate generalisations, the reluctance to abandon the historical model of de-peasantisation, and opposing beliefs about how to evaluate socio-economic consequences created a Rashomon Effect that made the controversy hard to resolve.
