Gunshot injuries of the brain caused by air pressure guns

The article describes the historical and legal basis, as well as the ballistic criteria of injuries caused by air-rifle shots to the head. Six of our own cases of craniocerebral air-gun pellet injuries are discussed and critically assessed, using the results communicated in other papers as the basis of the discussion. The different post-traumatic complications, including the histopathological reaction of the brain to lead-pellets, are considered. The literature is reviewed and the indications for stereotactic removal or craniotomy of intracranial air-gun pellets are discussed. Air rifles, while occasionally the cause of serious head injuries, are rarely thought of as lethal weapons. However, this article illustrates the potential penetrating power of the air-gun pellet, a fact not always appreciated by physicians.     

Self-inflicted penetrating head injury in a patient with manic-depressive disorder

A 32-year-old Caucasian male with a history of repeated self-injury drilled a hole in his skull using a power tool and subsequently introduced intracerebrally a binding wire from a sketch pad. An emergency craniotomy was performed around the site of cranial injury, and the foreign body was carefully extracted. The wire was located partially in the subdural space and partially in the right hemisphere of the brain. The patient made an excellent recovery and was referred to a psychiatrist for further treatment. This is a rare case of unusual and complex repetitive self-destructive behavior without apparent suicidal intent. The pertinent literature is reviewed and the surgical and psychiatric implications of such injuries are discussed.     

Role of preoperative 3-dimensional computed tomography reconstruction in depressed skull fractures treated with craniectomy: a case report of forensic interest

Patients affected by cranial trauma with depressed skull fractures and increased intracranial pressure generally undergo neurosurgical intervention. Because craniotomy and craniectomy remove skull fragments and generate new fracture lines, they complicate forensic examination and sometimes prevent a clear identification of skull fracture etiology. A 3-dimensional reconstruction based on preoperative computed tomography (CT) scans, giving a picture of the injuries before surgical intervention, can help the forensic examiner in identifying skull fracture origin and the means of production.We report the case of a 41-year-old-man presenting at the emergency department with a depressed skull fracture at the vertex and bilateral subdural hemorrhage. The patient underwent 2 neurosurgical interventions (craniotomy and craniectomy) but died after 40 days of hospitalization in an intensive care unit. At autopsy, the absence of various bone fragments did not allow us to establish if the skull had been stricken by a blunt object or had hit the ground with high kinetic energy. To analyze bone injuries before craniectomy, a 3-dimensional CT reconstruction based on preoperative scans was performed. A comparative analysis between autoptic and radiological data allowed us to differentiate surgical from traumatic injuries. Moreover, based on the shape and size of the depressed skull fracture (measured from the CT reformations), we inferred that the man had been stricken by a cylindric blunt object with a diameter of about 3 cm.     

Punched with a fist: the etiology of a fatal depressed cranial fracture

We report a case in which a 33-year-old man was discovered unconscious following a fistfight with another man. Emergency neurosurgical efforts to repair a depressed temporoparietal skull fracture and associated brain injuries were unsuccessful. The forensic anthropologist and pathologist worked in tandem to sort out a complex combination of cranial evidence, including healed antemortem trauma, perimortem blunt force trauma, remote and recent neurosurgical intervention, and the craniotomy cut performed at autopsy. The victim had suffered head injuries and a right temporoparietal craniotomy ten years prior to death. The perimortem cranial fractures were centrally located within a surgically repaired roundel of bone involving portions of the right temporal and parietal bones. Reportedly, the victim was punched on the right side of his head as he was lying on the ground with the left side of his head against an asphalt surface. A primary question in the case was whether a blow with a fist could have produced the observed cranial injuries. To adequately answer that question, known data on the minimum amount of force required to fracture the temporoparietal region were compared to data on the amount of force generated by a blow with a fist. A biomechanics expert demonstrated that a single blow with a fist to the rigidly supported head of the victim could generate the required force to produce the observed fractures. The previous medical condition possibly predisposed the victim to the cranial fractures and contributed to the depressed nature of the fractures. Although depressed cranial fractures do not typically result from a blow with a fist, it was determined in this case that the fracture pattern was consistent with a punch to the head.     

Correlative Factors for Organic Psychotic Symptoms in Patients Following Traumatic Brain Injury

Objective To investigate the correlative factors for organic psychotic symptoms following trau matic brain injury （TBI）. Methods In the current study, 391 subjects who had undergone forensic iden tification of the organic mental disorders due to TBI were included, both the demographic and posttrau matic information collected. The relevant data were statistically analyzed in those confirmed as organic psychotic syndrome according to Chinese Classification of Mental Disorders 3rd version （CCMD3）. Re suits Fiftytwo subjects （13.3%） were identified as organic psychotic symptoms. The chisquare test showed that the detectable organic psychotic symptoms were associated with the marriage status, damage nature, injury severity and treatment, and the multivariate logistic regression analysis revealed good fitness of treatment and injury severity with the regression model （OR=0.044, 95% CI： 0.0170.114; OR=2.145, 95% CI： 1.201-3.832, respectively）. Conclusion The risks of organic psychotic symptoms following TBI can be involved in the alternative of craniotomy for the cases with trauma and moderate brain injury.     

Intracranial impalement with entrance site in the mandibular region: postmortem elucidation of an accidental fall on a wooden plant stick

A 78-year-old woman with a history of transient ischemic attacks was found in the doorway of her house in a somnolent and unresponsive condition. In the right mandibular region, a small skin wound was localized, which was surgically treated. Six days after admission to the hospital, an exploratory craniotomy was performed because of abnormal CT findings. Apart from tissue lesions and hemorrhages a small bone fragment was detected in the right cerebral cortex, which was removed. After 11 days in hospital, the patient died from failure of central regulatory functions. At the forensic autopsy, a 15 cm long wound track running upward from the skin wound in the right mandibular region through the bony skull base to the right parietal lobe of the brain was noted. Apparently, the surgically removed bone fragment had been displaced from the right middle cranial fossa. The site of the incident in the deceased's house was inspected again and a bamboo pole used to stabilize a potted plant standing on the floor was found and sent to the trace evidence laboratory. Analysis showed blood and tissue deposits from the victim. On the basis of all the findings and the circumstances of the case, a fatal impalement injury caused by an accidental fall could be assumed.     

Exposure to Property Crime as a Consequence of Poverty

This paper investigates whether and why the poor are more exposed to property crime than are the non‐poor, despite the reasonable assumption that poor people lack or have little valuable property that can be stolen. If poor people are more exposed to property crime than those who are not poor, there are needs for explanations. The paper investigates two plausible reasons: the significance of the neighbourhood character and routine activities. The results in the paper indicates that poor people are more exposed to property crimes related to the residence, independent of neighbourhood character and routine activities, while exposure to property crimes related to vehicles depends more on the family situation and age than on poverty per se. When it comes to other kinds of property crime, poor people do not seem to be more exposed than do the nonpoor. That poor people are more exposed to property crime related to their residence, and that there are problem areas explaining why, is worrisome. Those who are poor are often vulnerable to other social problems that tend to exclude them from ordinary living patterns. To find out the relation between poverty and exposure to property crimes related to residence is of importance for crime prevention and probably an important step to prevent those who are poor from being further excluded from society.     

Interpersonal violence cases reported to the police: a Nigerian study

The study involves 204 cases of interpersonal assault reported to the police during a period of 1 year. The patterns of domestic violence and community violence involving friends, neighbors, and strangers are described. The most common type of violence reported to the police is community interpersonal violence in which victims are mostly females and perpetrators are mostly males and members of gangs. Cases of rape are reported, whereas spousal violence tends to be underreported. On the whole, female victims are more likely to be younger than their male counterparts, whereas the male perpetrators are more likely to be unemployed. Repeat assault is found in 43 instances. Possible psychological and sociological explanations are offered for violent gang activities. The need to sensitize the police to become more involved is emphasized. The author proposes suggestions that may help reduce the incidence of community violence.     

西方法官职业的历史构建

法官的产生是由统治者（国王）渡让权力的结果。法官自设立之时起，就与正义联系在一起。由于各民族的特点不同，法官产生的路径是不一样的：既有从全社会中民主选举产生的，也有仅从贵族中民主选举产生的。早期的法官其实并非“官”，其在社会上的地位甚至排不上官僚的序列；早期的法官也不是由专家来担任的。司法腐败似乎是随司法权的产生而产生的。由选举产生法官的目的是为了防止腐败；而以任命的方式、以个人品德来产生法官的目的也是为了防止法官腐败，结果都没能制止司法的腐败。法官职业与其它职业一样，是社会分工和制度文明进步的必然产物。不同的政体性质也决定了法官的形式。司法的最终目的是为了保障司法独立。

THE SYSTEM LISTENS BUT DOES NOT HEAR

Throughout the land there has been a growing dissatisfaction with the programs and treatment carried on within institutions, especially those dealing with juveniles. This article attempts to pinpoint some of the reasons why institutions are unable to meet the challenge of delinquency in our society. On the one hand, impediments are inherent to the institutional system; on the other, due to outside forces and factors. they are beyond the control of the institution. Patchwork attempts to shore up a sagging, outmoded system are futile. The facets that perpetuate the present system are identified. and some of the decisions required to build a new system of child care are noted.     

NARCOTICS USE AND CRIME: A MULTISAMPLE,MULTIMETHOD ANALYSIS*

Various addict behaviors that are relevant to the narcotics-crime relationship are examined throughout the course of the addiction career. Anglo and Chicano methadone patients are studied and several methodological approaches are utilized. The data are representative of numerous critical periods within the addiction career as well as periods immediately preceding and subsequent to it. The results from the various methodological analyses converge to indicate that while involvement in property crime activities generally precedes the addiction career, after addiction occurs the highly elevated property crime levels demonstrated by addicts appear to be regulated by similarly high narcotics use levels. During periods of curtailed narcotics use produced by treatment, property crime levels are significantly reduced and become extremely low after termination of the addiction career. The findings are compared with results previously reported and new results are presented. Theoretical consideration of circumstances that significantly moderate the narcotics-crime relationship, such as geographic and sociodemographic differences, drug trafficking, and other behaviors, are discussed.

Modeling the longitudinal impact of legal sanctions on narcotics use and property crime

Structural equation models are used to confirm the suppressive effects of legal sanctions, e.g., probation and parole, on narcotics use and property crime. Both concurrent and longitudinal effects of legal sanctions are tested within two different models, which together span the entire addiction career. The findings indicate that (1) the suppressive effects of legal sanctions are evident only when legal sanctions are operationalized as parole or probation officer contact where urine monitoring is utilized; (2) only concurrent suppressive effects are statistically significant, and longitudinal suppressive effects are not; (3) both narcotics use and property crime are suppressed by legal sanctions, although the latter is less responsive than the former to intervention by the criminal justice system; and (4) suppressive effects tend to be more pronounced later in the addiction career. The significance of the findings and the implications for criminological theory related to issues regarding surveillance effects are emphasized.

An investigation into the differentiating characteristics between car key burglars and regular burglars

Car key burglary has recently become the focus of empirical investigation as offenders, no longer able to steal vehicles without first obtaining their keys, resort to "burgling" target properties. Research surrounding the modus operandi of these offenses is beginning to emerge; however, little attention has been paid to investigating the characteristics of car key burglary offenders. Challenging the assumption that car key burglary offenses are perpetrated by regular burglars, this study aims to differentiate between offenders. Logistic regression analysis of 110 car key and 110 regular burglary offenders revealed that car key burglars are more likely to have previous vehicle theft convictions and are also more likely to be detected on information supplied to the police than regular burglars. Regular burglars are more likely to have previous shoplifting convictions. It was concluded that car key burglars are a distinct sample of offenders and the implications of these findings are discussed.     

DISTINCTIVE CHARACTERISTICS OF ASSAULTS MOTIVATED BY BIAS*

This research examines the ways in which assaults motivated by bias are similar to and different from other types of assault. Analyses are based on data from the National Incident Based Reporting System (NIBRS), pooled across eleven states. We find evidence suggesting that offenders motivated by racial and ethnic bias are more likely to be versatile offenders than specialists: they are more (not less) likely to be using drugs and alcohol during the crime than conventional offenders. Bias offenders are also more likely to seriously injure the victim. Finally, we find that the risks of bias crime victimization (relative to the risk of assault victimization generally) are similar for blacks and other racial minorities.     

Determination of illicit drugs in seized materials: role of sampling and analysis in estimation of measurement uncertainty

The determination of illicit active ingredients in seized materials, in order to assess penal or administrative offences, is routinely carried out in many forensic toxicology laboratories. This paper presents main features of the protocol adopted in the Authors' laboratory for the above investigations. In particular, sampling and analysis are considered as the same measurement process quantifying their combined contribution to overall measurement uncertainty. Aspects concerning representative sampling in the case of single and multiple items are discussed. The effects of material heterogeneity are considered by analyzing separately distinct primary samples taken from different parts of the sampling target. Possible errors due to particles dimension that could arise when sub-sampling are also considered. Analytical precision, bias and other matrix effects are studied in order to quantify the component of the overall measurement uncertainty associated to the analysis of prepared test samples. Typical scenarios arising when measurement results are used to assess compliance with specification limits are also discussed revealing the crucial role of measurement uncertainty.     

Randomized experiments as the bronze standard

In this paper, the strengths and weakneses of randomized field experiments are discussed. Although it seems to be common knowledge that random assignment balances experimental and control groups on all confounders, other features of randomized field experiments are somewhat less appreciated. These include the role of random assignment in statistical inference and representations of the mechanisms by which the treatment has its impact. Randomized experiments also have important limitations and are subject to the fidelity with which they are implemented. In the end, randomized field experiments are still the best way to estimate causal effects, but are a considerable distance from perfection.     

Political Liberties and Social Equality

This paper examines the link between political liberties and social equality, and contends that the former are constitutive of, i.e. necessary to secure, the latter. Although this constitutive link is often assumed in the literature on political liberties, the reasons why it holds true remain largely unexplored. Three such reasons are examined here. First, political liberties are constitutive of social equality because they bestow political power on their holders, leaving disenfranchised individuals excluded from decisions that are particularly pervasive, coercively enforced, hard to avoid, monopolistic, and final. Second, they are constitutive of social equality due to their positional value, such that those who are denied such liberties are socially downgraded because and to the extent that others enjoy them. Third, they are constitutive of social equality due to their expressive value, in the sense that, by disenfranchising some individuals, the state publicly fails to recognize their equal moral agency. While unpacking these reasons, we address some criticisms of this constitutive link recently raised by Steven Wall and Jason Brennan.
