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.     

Effect of Wind on Horizontal Displacement of Fatal Fall from a Height

The horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls.     

State power, state embeddedness, and national development in less developed countries: A cross-national analysis

In this article, we test the prevailing statist argument about the state’s contribution to economic development in less developed countries (LDCs). State power in terms of centralized control of societal resources has been long considered a primary factor for economic growth. From the embeddedness perspective, the state’s effective embedding in the economy advances productive growth, while state power actually operates as a structural precondition of such policy action. Featured in our measurement are representative and financial embeddedness (operationalized as the central government’s tax income and its lending to the private sector and local states, respectively). The empirical testing is based on a pooled cross-national data of sixty-one underdeveloped countries. As indicated from modeling both manufacturing growth and increase in GNP per capita as dependent variables (during the period 1975–1990), the state power variable does not produce expected growth outcomes. However, two embedded state measures display significant but sectorbiased growth effects only for manufacturing production. Herein we further compare strong state power countries with weak ones, concluding that state power serves as a structural prerequisite so that late industrialization for LDCs can benefit from the growth coalitions in which the central state collaborates with (rather than dominates) actors at the subnational level of society and authorities.

多层次一体化与东南亚地区发展前景

我们可以明显发现,世界在21世纪初正以多层次模式重组人类社会的互动关系,除了有最高层次的国际组织(以世界贸易组织为代表)外,还有代表传统国家利益的地区建制(例如欧盟与北美自由贸易区),此外便是次地区甚至微地区的一体化发展.对此,本文将由分析相关理论架构的发展切入,然后从次地区、微地区与地区层次,对东南亚地区进行分析,希望能有助于了解这一地区一体化发展的现实与未来.     

Working Overtime in East Asia: Convergence or Divergence?

Working long hours has become a routinised part of life in East Asia. The different patterns of overtime across this region are understudied, however. This study represents a first systematic attempt to analyse overtime and its determinants in Japan, South Korea, Taiwan and China by testing hypotheses that specify the distinctive influences of employment status and job contracts on work hours. Class exploitation, post-industrialism and flexibility theories are mobilised to identify distinctive but supplementary factors in long working hours. Using data from a recent four-country survey, a Tobit regression analysis of full-time workers’ hours reveals that employers and self-employed people work longer hours than hired workers across this region. Despite this convergence, there is a contrast across occupations. In Japan, overtime is positively associated with occupational prestige, while a reverse pattern operates in China, where low-skilled workers work more overtime. Contract workers in the private sector in South Korea and China also have longer overtime when compared to public sector employees. In sum, this study highlights more divergence than convergence of working conditions within East Asia.     

A Retrospective Population-Based Study of Hospitalized Injuries Associated with Intimate Partner Violence in Taiwan from 1997 Through 2009

The study used Taiwanese National Health Insurance Research Database to investigate the types of injuries suffered by those patients hospitalized for intimate partner violence and the types of hospital care provided to victims 18 years of age or older from 1997 to 2009. In total, there were 836 cases and 3.57 times more female than male, the average hospital stay length was 9.37 days, and the average hospital costs totaled approximately NT$ 47,563.53. On average, there were approximately 2.86 injuries per abuse victim, and intracranial injuries were the most common injury (28.83 %). Many of the abused patients went to regional hospitals (44.14 %), and the largest percentage of hospitalized patients (50.24 %) was among 25–44-year-olds. In the study period, the hospitalization rate for females was significantly higher than for males; moreover, the overall rate of hospitalization for intimate partner violence increased significantly.     

Cytochrome b gene for species identification of the conservation animals

A partial DNA sequence of cytochrome b gene was used to identify the remains of endangered animals and species endemic to Taiwan. The conservation of animals species included in this study were: the formosan gem-faced civets, leopard cats, tigers, clouded leopards, lion, formosan muntjacs, formosan sika deers, formosan sambars, formosan serows, water buffalo, formosan pangolins and formosan macaques. The control species used included domestic cats, domestic dogs, domestic sheeps, domestic cattles, domestic pigs and humans. Heteroplasmy was detected in the formosan macaque, domestic pig and domestic cats. The frequencies of heteroplasmy in these animals were about 0.25% (1 in 402bp). Sequences were aligned by Pileup program of GCG computer package, and the phylogenetic tree was constructed by the neighbor-joining method. The results of sequence comparison showed that the percentage range of sequence diversity in the same species was from 0.25 to 2.74%, and that between the different species was from 5.97 to 34.83%. The results of phylogenetic analysis showed that the genetic distance between the different species was from 6.33 to 40.59. Animals of the same species, both the endangered animal species and domestic animals, were clustered together in the neighbor-joining tree. Three unknown samples of animal remains were identified by this system. The partial sequence of cytochrome b gene adopted in this study proved to be usable for animal identification.     

The Influence of Footwear Sole Hardness on Slip Characteristics and Slip‐Induced Falls in Young Adults

Theoretically, a shoe that provides less friction could result in a greater slip distance and foot slipping velocity, thereby increasing the likelihood of falling. The purpose of this study was to investigate the effects of sole hardness on the probability of slip‐induced falls. Forty young adults were randomized into a hard or a soft sole shoe group, and tested under both nonslippery and slippery floor conditions using a motion analysis system. The proportions of fall events in the hard‐ and soft‐soled shoe groups were not statistically different. No differences were observed between shoe groups for average slip distance, peak and average heel velocity, and center of mass slipping velocity. A strong association was found between slip distance and the fall probability. Our results demonstrate that the probability of a slip‐induced fall was not influenced by shoe hardness. Once a slip is induced, slip distance was the primary predictor of a slip‐induced fall.
