全球减排路线图的正义性——对胡鞍钢教授的全球减排路线图的评价与修正

任何全球减排路线图的绘制都无法脱离国际正义而具有生命力。气候变化问题的特性要求全球减排路线图尊重具有两面性的国际气候正义:环境正义和发展正义,需要考虑国家间公平、人的公平和代际公平。仅以人类发展指数(HDI)作为衡量国家承担减排责任的标准缺乏足够的正义,至少还需要加入人均历史累积排放和气候变化脆弱性两个指标。三者分别体现气候变化正义性中的人的平等发展权、减排责任分担和对受害者在排放权上的补偿。综合三大指标后的四分组分类,才是更体现正义性、更容易被接受和执行的路线图。从正义性出发,中国应承担相应的减排责任,并努力推动全球减排进程,但也要注意维护自身的发展权益。中国在全球减排中的作为,应是在国际正义与国家发展战略间取得平衡。     

Perceived parental rearing practices and styles of coping

In order to study the relation between parental rearing practices and coping dispositions, 75 females and 65 males completed the Children's Report of Parental Behavior Inventory and the COPE, a measure of general coping dispositions. Those who reported their parents had an authoritative rearing style (warmth and nurturance coupled with close monitoring and age-appropriate demandingness) used more social support and problem-focused coping than those who reported their parents used other rearing styles. In general, perceived parental warmth was related to the greater use of social support and problemfocused coping. Parental firm control was associated with increased problemfocused and reduced emotion-focused coping. The findings are discussed in the context of parental rearing styles indirectly influencing coping dispositions through their impact on feelings of competence and personal control.This research is based on a masters thesis conducted by the first author under the direction of the second author. Portions of this study were presented at the March 1992 Meetings of the Society for Research on Adolescence, Washington, DC.Received Ph.D. from Syracuse University. Research interests include adolescent coping processes.Received Ph.D. from University of Illinois-Urbana. Research interests include adolescent self development and coping.     

Public policy evaluation in France

The future of public policy evaluation in France seems at once promising and uncertain. Although the signs of development are evident-increasing numbers of evaluations, aroused public and parliamentary interest, active administrative involvement-the process is not uniform, codified, or generally rigorous. The administration itself is the chief initiator of evaluations, possessing the greatest resources, yet only in a small minority of instances are the ideal conditions of evaluation met. Strong political pressure would almost certainly be essential to move the government toward the institutionalization of an effective appraisal system.     

Burkina Faso: Between Taiwan's active public diplomacy and China's business attractiveness

Burkina Faso and Taiwan restored official relations in 1994, after which Taipei's aid has been generous. Taiwan's approach to official development assistance has remained largely traditional, closely linking its public diplomacy to its foreign policy objectives. Trade between both countries has remained very modest. In the same period, because of mainland China's rise and active strategy of ‘going out’, Burkina Faso has developed a robust trade and business relationship with China. As a result, the pull to establish official ties with China (and thus end ties with Taiwan) has become a domestic political issue. After the ousting of President Blaise Compaoré in 2014, a failed coup and then the return to democracy as seen in the November 2015 elections, this debate has become more public. While Burkina Faso has remained faithful to Taiwan and continues to publicly appreciate its assistance, there is no certainty that the political values that both Burkina Faso and Taiwan share will prevent a Burkinabe move towards China.     

The detection of clandestine graves in an arid environment using thermal imaging deployed from an unmanned aerial vehicle

The Middle East is one of the world regions that has frequently suffered from armed conflicts that resulted in mass burials. However, the detection of clandestine graves in such an arid environment by deploying remote sensing payload on unmanned aerial vehicles (UAVs) has received little attention. The present study used a UAV equipped with a thermal sensor aimed at narrowing down the search area of possible gravesites in the arid climate of Kuwait. The enclosed research area, which includes both control and experimental mass graves, was imaged for 18 months. The variation in topsoil temperature and soil moisture between the graves and their surroundings was evaluated. The results of the analysis demonstrated the effectiveness of thermal imaging techniques in detecting heat produced from buried sheep carcasses and detecting the change in grave soil moisture for our research environment for 7 and 10 months, respectively. The buried animals significantly influenced the topsoil temperature (p = 0.044), while the height from which the images were captured had an insignificant effect on the measured temperature within the range tested (p = 0.985). Furthermore, there was a negative correlation (−0.359) between grave temperature and the calculated soil moisture. The results from these cost- and time-effective search methods presented in this study confirm their potential for the detection of burial sites in an arid environment.     

Review of analytical methods for screening and quantification of fentanyl analogs and novel synthetic opioids in biological specimens

Fentanyl, fentanyl analogs, and other novel synthetic opioids (NSO), including nitazene analogs, prevail in forensic toxicology casework. Analytical methods for identifying these drugs in biological specimens need to be robust, sensitive, and specific. Isomers, new analogs, and slight differences in structural modifications necessitate the use of high-resolution mass spectrometry (HRMS), especially as a non-targeted screening method designed to detect newly emerging drugs. Traditional forensic toxicology workflows, such as immunoassay and gas chromatography mass spectrometry (GC–MS), are generally not sensitive enough for detection of NSOs due to observed low (sub-μg/L) concentrations. For this review, the authors tabulated, reviewed, and summarized analytical methods from 2010–2022 for screening and quantification of fentanyl analogs and other NSOs in biological specimens using a variety of different instruments and sample preparation approaches. Limits of detection or quantification for 105 methods were included and compared to published standards and guidelines for suggested scope and sensitivity in forensic toxicology casework. Methods were summarized by instrument for screening and quantitative methods for fentanyl analogs and for nitazenes and other NSO. Toxicological testing for fentanyl analogs and NSOs is increasingly and most commonly being conducted using a variety of liquid chromatography mass spectrometry (LC–MS)-based techniques. Most of the recent analytical methods reviewed exhibited limits of detection well below 1 μg/L to detect low concentrations of increasingly potent drugs. In addition, it was observed that most newly developed methods are now using smaller sample volumes which is achievable due to the sensitivity increase gained by new technology and new instrumentation.     

Occupational exposure to traumatic evidence and posttraumatic stress symptoms in forensic science professionals: Prevalence and patterns

Forensic science professionals are routinely exposed to potentially traumatizing evidence. This study aimed to estimate the prevalence of occupational posttraumatic stress disorder (PTSD) among forensic science professionals, identify job-related correlates of PTSD symptoms, and examine the role of social support in mitigating PTSD symptomology. In response to recruitment through the American Academy of Forensic Sciences, the American Society of Crime Laboratory Directors, and Evidence Technology Magazine, 449 forensic science professionals participated in the current study. Results found that 73.5% (n = 330) of the overall sample experienced at least one work-related traumatic event consistent with meeting Criterion A for PTSD, and these rates were higher for field-based respondents (n = 203, 87.9%). The prevalence of past-month provisional PTSD was 21.6% for the full sample. Disaggregated PTSD rates were 29.0% and 14.5% for field-based and non-field-based respondents, respectively. These rates were 6- to 8-fold higher than the past-year prevalence of PTSD in the general US population, estimated to be 3.5%, and were found to be at least as high as those observed in prior epidemiological research with non-treatment seeking members of the US military deployed to war zones in Iraq and Afghanistan. Results further showed that social support was protective against PTSD symptomology. The high rates of occupational exposure to trauma and consequent PTSD symptomology observed in this large sample of forensic science professionals highlight the under-acknowledged psychological risks of these occupations and the need for enhanced attention to mental health resources for these professionals.     

Geoforensic search to crime scene: Remote sensing,geophysics, and dogs

In the absence of surface indications of burial sites, law enforcement or humanitarian organizations are faced with the difficult task of focusing large-scale ground searches to a manageable excavation area. A geoforensic-based survey may exclude parts of the landscape for reasons such as diggability or viewshed analysis but leave areas still too large for invasive exploration. This work examines how drone-based remote sensing, geophysics, and search dogs may be combined to narrow such searches. Here, we ask the reader to consider two examples where forensic geomorphology and land use provided a range of possible burial locations. Following this is a multi-proxy approach to similar dilemma, with a search-to-scene case study using remote sensing (drone photography), geophysics, ground probes, and search dogs. This approach is not presented as a definitive guide, but serves as an example of the conjunctive use of well-studied methods to approach a common problem in geoforensics.
