OPTIMALITY CONDITION OF PLACE OF INJURY RULE IN CROSS-BORDER INTERNET TORTS AND IMPLICATIONS FOR TURKEY

Place of injury rule is not always optimal. In this paper, we measure the optimality condition of place of injury rule under strict liability. We develop an extended new model that departs from the efficient condition of choice of law rule by O＇Hara ＆ Ribstein2. The first part of our model proposes the optimal amount of precaution in cross-border internet torts under strict liability. The second part of the model indicates the optimality condition of the place of injury rule. Our model shows that the choice of injury rule is not always optimal However, Article 34/II of Turkish Act on Private International and Procedural Law accepts that the choice of injury rule is always optimal so that Article 34/11 is inefficient and wealth destroying. In conclusion, we suggest that Article 34/11 should not be a mandatory rule. It should grant discretion to judges in order to measure the optimality conditions of both place of injury rule and place of conduct rule in each case. Our model will guide judges to measure the optimality conditions of choice of law rules.     

ESTIMATING A DOSE‐RESPONSE RELATIONSHIP BETWEEN LENGTH OF STAY AND FUTURE RECIDIVISM IN SERIOUS JUVENILE OFFENDERS*

The effect of sanctions on subsequent criminal activity is of central theoretical importance in criminology. A key question for juvenile justice policy is the degree to which serious juvenile offenders respond to sanctions and/or treatment administered by the juvenile court. The policy question germane to this debate is finding the level of confinement within the juvenile justice system that maximizes the public safety and therapeutic benefits of institutional confinement. Unfortunately, research on this issue has been limited with regard to serious juvenile offenders. We use longitudinal data from a large sample of serious juvenile offenders from two large cities to 1) estimate a causal treatment effect of institutional placement, as opposed to probation, on future rate of rearrest and 2) investigate the existence of a marginal effect (i.e., benefit) for longer length of stay once the institutional placement decision had been made. We accomplish the latter by determining a dose‐response relationship between the length of stay and future rates of rearrest and self‐reported offending. The results suggest that an overall null effect of placement exists on future rates of rearrest or self‐reported offending for serious juvenile offenders. We also find that, for the group placed out of the community, it is apparent that little or no marginal benefit exists for longer lengths of stay. Theoretical, empirical, and policy issues are outlined.

本文应用显微荧光分光光度计法研究大白鼠皮肤创缘组织中组胺的分布和含量,并用甲苯胺蓝法观察创缘肥大细胞形态和数量的变化。结果发现,创缘真皮乳头层出现扩散的细胞外黄色荧光和肥大细胞脱颗粒现象为生前伤的重要特点;组胺荧光分布范围及增多的程度与损伤时间密切相关。从而为损伤时间推断提供了一种新的方法。     

200例活体损伤程度鉴定分析

本文对200例活体损伤程度的鉴定进行了统计和分析(1983～1986)。结果表明:重伤占42.5%,轻伤占57.5%。男性占83.5%,女性16.5%。年龄以青少年组为多。致伤物以拳脚占首位。损伤部位以颅脑损伤最多。并发症的出现率为20.5%;后遗症的出现率为38%。本文对原发性损伤、并发症、后遗症在活体损伤程度鉴定中的重要意义亦进行了讨论。     

白三烯含量的测定推断损伤时间实际应用的探讨

本文利用高压液相色谱法，检测大鼠切创创缘10％福尔马林固定皮肤检材的白三烯B4（LTB4）含量，结果发现：大鼠生前切创检材中LTB4含量增加，在1小时内其含量与损伤时间呈线性关系；死后伤未检见LTB4。随着福尔马林固定时间的延长，含量明显下降，但1周内仍可测出。     

根据X线片跖趾骨长宽度推算0～17岁个体身高年龄

本文通过1607例儿童青少年跖趾骨长度和宽度与身高和年龄的相关回归分析，发现两者之间呈高度正相关，相关系数γ=0．859～0．998，相关检验和回归检验P＜0．0025～0．0005，据此分别计算出各跖趾骨长度、宽度推算身高、年龄的直线回归方程，为法医学、人类学提供了基础资料。     

脑死亡后神经细胞溶酶体酸性磷酸酶变化的研究

在颅内高压致脑死亡动物模型基础上采用酶细胞化学技术对脑死后不同水平神经细胞溶酶体酸性磷酸酶(AcidPhosphatase,ACP)活性变化和定位分布作了同步观察.结果显示,脑死亡后神经细胞ACP活性先增高,继而逐渐降低乃至消失,以大脑和小脑神经细胞为著;脑干神经细胞ACP一直保持较高活性;脑死亡9h内ACP定位无改变.表明神经元ACP活性改变可能是脑死亡神经病理学变化的发病机制之一.     

北京地区法医昆虫学研究──Ⅱ.尸体分解过程中的昆虫种类演替与死亡时间推断

在调查北京地区嗜尸性昆虫物种谱系的基础上，进一步研究了在尸体分解过程中，昆虫种类的演替特点及其对死亡时间推断的价值。嗜尸性昆虫侵食尸体的过程可分为侵入期、分解期和残余期：侵入期以双翅目蝇类为主，时间推断以幼蛆的发育程度为依据；分解期出现大量鞘翅目种类，时间推断以甲虫的各类组成、数量以及演替特征为主要依据；残余期昆虫数量极少。季节及温度、环境条件、尸体是否受伤或裸露，是影响昆虫侵食尸体时序的三个重要因素。正常的春季，侵入期为8至25天，分解期为约42天。

ON AMBIGUITY IN PERCEPTIONS OF RISK:IMPLICATIONS FOR CRIMINAL DECISION MAKING AND DETERRENCE*

Deterrence theorists and researchers have argued that the critical dimension of sanction certainty is its level—increasing the certainty of punishment from a lower to a higher level will inhibit criminal conduct. However, the true certainty of punishment is rarely known with much precision. Both Sherman (1990) and Nagin (1998) have suggested that ambiguity about the level of punishment certainty is itself consequential in the decision to commit or refrain from crime. Here, we investigate this proposition. We find some evidence that individuals are “ambiguity averse” for decisions involving losses such as criminal punishments. This finding means that a more ambiguous perceived certainty of punishment is a greater deterrent of some crimes than a nominally equivalent but less ambiguous one. However, this effect depends on how large an individual's risk certainty perception is initially. That is, we find evidence for “boundary effects” (Casey and Scholz, 1991a, 1991b) in which this effect holds for lower probabilities but reverses for higher ones. For higher detection probabilities, individuals become “ambiguity seeking” such that a less ambiguous detection probability has more deterrent value than a nominally equivalent but more ambiguous detection probability. Results are presented from two distinct, but complementary, analysis samples and empirical approaches. These samples include a survey to college students with several hypothetical choice problems and data from the Pathways to Desistance study, a longitudinal investigation of serious adolescent offenders transitioning from adolescence to young adulthood.     

A NEW METHOD FOR STUDYING THE EXTENT,STABILITY, AND PREDICTORS OF INDIVIDUAL SPECIALIZATION IN VIOLENCE*

Specialization in violence is an important scientific and policy topic, and over the past several decades, many analysis techniques for studying specialization have emerged. Research in this area continues to be hampered, however, by remaining methodological problems. To overcome these problems, we propose a new method for studying specialization in violence based on an item‐response theory measurement approach that is implemented through a multilevel regression model. Our approach defines specialization as an individual level latent variable, takes into account the inherent confounds between specialization and overall level of offending, and gauges specialization relative to the population base rates of each offense. Our method also enables researchers to 1) estimate the extent and statistical significance of specialization, 2) assess the stability of specialization over time, and 3) relate specialization to explanatory variables. Using data from three studies, we found substantial levels of specialization in violence, considerable stability in specialization over time, and several significant and relatively consistent relationships of specialization to explanatory variables such as gender, parental education, and risk‐seeking.
