Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

论良法的恶性循环

人们崇尚良法,期冀良法之治,却在翘首与热望中忘却了良法亦需适宜的土壤。当良法出台后,因土壤导致的“水土不服”很可能让良法之良本身遭到质疑,这是令人尴尬的一种真实。良法如果遭遇故意误读,在司法中将会陷入一种可怕的恶性循环。从这一视角解析实践中的许多案例,能使我们揭开隐于表象后的本质,同时打开索解之结。     

浅析公务员职位轮换中存在的问题及对策

笔者认为,在我国地方现阶段实行公务员轮换的过程中,存在着诸如轮换周期不合理、随意轮换、离任审计不彻底、制度不健全等诸多问题,因而给政府工作带来一些负面效应。本文试图分析公务员职位轮换中存在的这些问题并寻求相应对策,以期达到实行公务员职位轮换应有的目的。     

Analyses factorielles et choix méthodologiques: réplique à Markus Freitag

In this contribution, we discuss the number of factors to consider as well as the consequences of rotation in the case of principal components analysis, a technique belonging to the family of factor analysis. The article by Freitag in this issue, dedicated to the study of social capital in Switzerland, is used as example. This contribution shows the impact of different missing values estimations and, more generally, stresses the importance of looking at different solutions in an exploratory perspective. It underscores also the importance to have access to the data in order to allow a new analysis and, consequently, the possibility of the scientific debate.     

Stealing into the wild: conservation science,plant breeding and the makings of new seed enclosures

Faced with pressing climatic changes, scientific and industrial interests are vying to develop crops that can survive drought, floods and shifting pest regimes. Increasingly, they look for solutions in an unlikely place: the gene pools of wild plants. Crop wild relatives (CWR) – species closely related to crops, including their ancestors – offer breeders the allure of retracing the domestication bottleneck, infusing genomes of modern crops with ‘lost’ genetic variety. Yet wild relatives also confront threats from climate change, urbanization and expansion of industrial agri-food. Thus, CWR, seen as both salvational and threatened, have become an international conservation and food-security priority. It is my contention that, in their common project to harness wild-relative potential, conservation and breeding science are co-evolving to extend seed commodity relations into new spheres. I examine enclosures along two fronts: first within ‘systematic CWR conservation’, where ‘in situ’ approaches, typically regarded as empowering and sustainable alternatives to ‘ex situ’, instead may support a complementary system of value extraction; second, in breeding and biotechnology research, which produces new value for CWR while profoundly shaping upstream conservation priorities. An important finding is that although today’s ‘ex situ-centric’ complementarity favors dispossession, an ‘in situ-centric’ approach could foster democratic renewal of biocultural diversity.     

The ‘rule of experts’ in making a dynamic micro-insurance industry in India

India is reported to have the most dynamic micro-insurance market in the world and the largest weather-index insurance market among developing countries. This is interesting because, paradoxically, reports readily suggest that the primary hindrance for the industry is the widespread lack of effective demand for insurance. This paper seeks to identify, understand and problematize the paradox of resolutely promoting micro-insurance and its apparent rapid growth despite a manifest absence of demand for insurance. Neo-classical theories about risk-averse behaviour do not explain the current lack of appeal of insurance among the poor. Rather, I draw on a postcolonial political economy framework to argue that expert investment in getting prices and culture right while safeguarding micro-insurance supply currently explains the celebrated dynamism of Indian micro-insurance. I argue that promoting comprehensive institutional reform for an ideal investment and entrepreneurial climate involves securing mutually beneficial linkages, collaborations and knowledge within a broad assemblage of profit motives, insurance expertise, policy-makers and professionals. Insurance experts rule by promoting the micro-insurance sector while simultaneously investing in and gaining from discursive, material and pedagogical construction of this industry. Future research should address whether such processes and products are effective in managing financial risks of the poor.     

Columnar‐Thin‐Film‐Assisted Visualization of Depleted Sebaceous Fingermarks on Nonporous Metals and Hard Plastics

A fingermark on a nonporous substrate can be developed by depositing a columnar thin film (CTF) on it, but the CTF technique's sensitivity for low‐quality fingermarks is unknown. The optimized CTF and traditional development of several depletion series of sebaceous‐loaded fingermarks were compared using a split‐print methodology as well as subjective and objective grading schemes, in a limited laboratory trial. CTF development was superior to development with selected traditional techniques on brass, anodized aluminum, black acrylonitrile butadiene styrene (ABS), and white nylon. On white ABS and black nylon, the CTF technique performed poorly but still as well as the best‐performing traditional development technique. The CTF technique was more sensitive on brass and anodized aluminum than, and as sensitive on the four hard plastics and stainless steel as, the best‐performing traditional technique. Thus, the CTF technique is useful to develop friction‐ridge detail from limited fingermark residue on some smooth substrates.     

Female student athletes’ perceptions of acceptability and the occurrence of sexual-related behaviour by their coaches in India

The current study assessed the perceptions of acceptable sexual behaviour of coaches and the occurrence of sexual harassment among female student in India. A sample of 180 Indian female student-athletes at intercollegiate and inter-university levels with male coaches participated in this study. A questionnaire on sport-specific Touch and Behaviour versus Unwanted Intimacy from coaches (Vanden Auweele et al., 2008), consisting of 41 items on a 5-point rating scale was used. The participants were asked to indicate the acceptability of specific coaching behaviour as well as the occurrence of the behaviour represented in each item. The acceptability of the behaviour was determined by means and standard deviations, while the occurrence was determined by frequencies. Factor analysis was performed to determine the structure of the coaches’ behaviour and athletes’ acceptability thereof, which yielded four factors. Cronbach’s alpha was used to determine the internal consistency of the extracted items on each factor. Two factors, namely, unwanted sexual behaviour and inappropriate verbal and physical sexual behaviour, were regarded by athletes as very serious and unacceptable coach behaviour, while a third factor represented context-dependent suspicious behaviour (a grey area in which athletes differ in their opinion) and was perceived to be serious and unacceptable. A fourth factor represented acceptable behaviour. The occurrence of very serious and unacceptable behaviour was reported by 31% of the female athletes.     

Political economy of land grabbing inside China involving foreign investors

China tends to be a dominant figure in the literature on global land grabbing. It is either cast as a major land grabber in distant places such as Africa, or as a key player in crop booms elsewhere because it provides for massive market demand, such as for soya from South America. These are all important issues and are well covered in the literature. However, the crop booms inside China that involve transnational capital and investors – and have provoked conflict around land politics – have been overlooked. Spotlighting the issue of land grabbing inside China reminds us that capital accumulation is principally interested in geographies and settings where it can generate profit – regardless of nationalities, boundaries, structural or institutional conditions. This paper hopes to contribute towards a more refined picture of global land grabbing.
