Incidental findings in CT colonography: literature review and survey of current research practice

Incidental findings (IFs) of potential medical significance are seen in approximately 5-8 percent of asymptomatic subjects and 16 percent of symptomatic subjects participating in large computed tomography (CT) colonography (CTC) studies, with the incidence varying further by CT acquisition technique. While most CTC research programs have a well-defined plan to detect and disclose IFs, such plans are largely communicated only verbally. Written consent documents should also inform subjects of how IFs of potential medical significance will be detected and reported in CTC research studies.     

Sibling incest: A literature review and a clinical study

Abstract

Few previous studies have explored the characteristics and dynamics of adolescent sibling incest. The objectives of this paper were twofold: first, to conduct a literature review that accounts for earlier research in the area, and secondly, to conduct a clinical study to explore differences regarding the characteristics of a group of adolescent sibling incest offenders (n=21) compared to a group of adolescent non-sibling offenders (n=24). Comparisons were made regarding variables such as family dysfunction, the offenders' prior victimization and offending behaviour. The data were derived from intake assessment files and semi-structured interviews with 45 adolescents who had sexually offended. The sibling incest offender group had grown up more often in dysfunctional families. Moreover, the results indicated that the offending behaviour in the sibling incest group was more severe. The study gives some empirical support for the possibility that sibling incest can be one sign, among others, of maltreatment during childhood.     

Community crime prevention: A review and synthesis of the literature

In the absence of effective formal means for controlling crime in the Western world, community crime prevention has emerged as a major alternative and supplement to the criminal justice system. This article attempts to review what is known currently about the nature, extent, and effectiveness of community-based efforts to prevent residential crime. Included in this assessment are citizen actions to protect themselves, their property, and their neighborhood, as well as efforts to prevent crime through changes in the physical environmental and through innovations in community policing. The historical, theoretical, and empirical rationale for community crime prevention strategies are discussed, but primary attention is given to the results of evaluation research in the field. Although community-based efforts are supported widely by theory, studies of natural covariation, and by numerous poorly designed evaluations, there is a paucity of strong demonstrations and evaluations showing that such interventions can alter the behavior and local environments of persons who are not already predisposed to crime prevention. Substantially more research is needed to determine the collective benefits of community crime prevention strategies, but a number of promising approaches currently are being developed.     

Organization structure as a factor in innovation: A review of the literature

There are several approaches to the organization of an activity. Some of the better known methods are by function, project or a matrix. Each of these methods is investigated in terms of its effect on innovation. Some of the advantages and disadvantages of each are discussed. All discussion is carefully supported by reference to current literature.     

International sex offender registration laws: research and evaluation issues based on a review of current scientific literature

In many jurisdictions, anyone convicted of a sexual offense is required to register with police, often for life. Nine different countries have now implemented sex offender registries in an attempt to protect the public from the perceived threat posed by sexual offenders. Yet such laws have been criticized as being overly inclusive, tying up limited law enforcement resources to track many offenders who pose little risk of sexual reoffending. This paper considers the available research evidence relevant to the effectiveness of such laws for the deterrence of sexual offending and the investigation of sex crimes. It is concluded that significant gaps persist in our knowledge of whether existing laws effectively reduce sexual offending or reoffending and that large-scale, well-designed studies of the impact of sex offender registration on rates of offending, the collateral consequences to offenders and their families, and the costs of such laws are needed.

Thy brother's keeper: A review of the literature on correctional officers

Individualized offender risk models do not account for expected reductions in risk that are caused by programmatic interventions, in part because of a presumption of program ineffectiveness. We examined two relatively unevaluated types of correctional programs—community-based prison release programs and prison furloughs—for adult males in the Massachusetts Department of Correction to determine whether there was an identifiable intervention effect on recidivism rates. We studied three samples of male inmates who were released during the 1970s, using base expectancy methodology to control for their background characteristics. We also examined 11-year trends in recidivism, comparing program participants to nonparticipants. Furlough participation, both alone and followed by prerelease, appears to have a pronounced and consistent positive impact on lowered recidivism. Implications for reintegration theory, risk assessment policy, and research are discussed.     

Joinder of criminal offenses: A review of the legal and psychological literature

Criminal courts routinely allow a defendant to be tried for multiple charges in a single trial. The practice is known as joinder of offenses. The issue of joinder of offenses is examined from a legal and psychological perspective. Relevant court decisions and their implications are discussed. In addition, the recent research conducted by social scientists concerning the possible reasons for the prejudicial effects of joinder of offenses is critically reviewed. Suggestions are offered, based upon previous joinder research, for the direction of future research into the loci of the effect and into potential remedies.This paper is an elaboration of one presented at the annual meeting of the Academy of Criminal Justice Sciences, Chicago, March 1984.     

Wife assault theory,research, and treatment: A literature review

Treatments for wife assaulters and their victims have been based on a variety of psychological and sociological theories. Tests of theory based on investigation of assailant and victim characteristics as well as evaluation of treatment effects based on empirical outcome studies have yielded diverse results. In reviewing the literature it appears that development of assailant typologies based on extent of psychopathology, severity of violence, and context of violence has potential utility in guiding future treatment decisions for assaulters. Further development of similar typologies for classifying responses of assaulted women could yield similar results. Population screening and matching programs to individual characteristics could be expected to improve clinical outcomes.     

Medicolegal death investigator workplace safety hazards: A scoping review of the literature

In the United States, medicolegal death investigation practices and policies pertaining to sudden unexpected deaths are mandated by state government. Practices vary across states, which contributes to inconsistency in job prerequisites and training. In preparation for a study focused on occupational safety and health of medicolegal death investigators in their on-scene and follow-up activities, a scoping review was conducted to document known occupational safety risks and health-related conditions associated with death investigation. Searches used Boolean and subject heading operators both broad and narrow in scope, and search terms included scene responder, hazard, investigator, forensic pathology, injury, and safety. Twenty-five articles met inclusion criteria, which included seventeen survey-mixed method designs, two systematic reviews, five quasi-experimental designs, and one case study. Twelve articles addressed mental health and eleven focused on risks associated with infectious disease. One article addressed the risk of chemical exposure from cyanide among autopsy personnel (including forensic pathologists) and nine included a wide range of employees within the setting of medical examiner or coroner offices. One article, addressing burnout, included employees in a forensic science laboratory setting as well as medicolegal death investigators and two articles included forensic pathologists and medicolegal death investigators. Only one article addressed medicolegal death investigators specifically. Articles addressing occupational and environmental hazards of medicolegal death investigators associated with musculoskeletal, respiratory, cardiovascular, radiological, nuclear, electrical, or explosive threats were not identified. There is little published about safety risks inherent in conducting death investigations. Research is needed to adequately inform health promotion and injury prevention strategies.     

A case of Ludwig angina: a case report and review of the literature

Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature.     

Fatal bilateral pneumothoraces after electroacupuncture treatment: A case report and literature review

Acupuncture is practiced as a complementary medicine worldwide. Although it is considered a safe practice, pneumothorax is one of its most common serious complications. However, there have been few reports of deaths due to pneumothorax after acupuncture treatment, especially focused on electroacupuncture. We report an autopsy case of a man in his 60s who went into cardiopulmonary arrest and died immediately after receiving electroacupuncture. Postmortem computed tomography (PMCT) showed bilateral pneumothoraces, as well as the presence of numerous gold threads embedded subcutaneously. An autopsy revealed two ecchymoses in the right thoracic cavity and a pinhole injury on the lower lobe of the right lung, suggesting that the needles had penetrated the lung. There were marked emphysematous changes in the lung, suggesting that rupture of bullae might also have contributed to bilateral pneumothoraces and fatal outcome. The acupuncture needles may have been drawn deeper into the body than at the time of insertion due to electrical pulses and muscle contraction, indicating the need for careful determination of treatment indications and technical safety measures, such as fail-safe mechanisms. This is the first case report of fatal bilateral pneumothoraces after electroacupuncture reported in the English literature. This case sheds light on the safety of electroacupuncture and the need for special care when administering it to patients with pulmonary disease who may be at a higher risk of pneumothorax. This is also the first report of three-dimensional reconstructed PMCT images showing the whole-body distribution of embedded gold acupuncture threads, which is unusual.     

To stay or quit: A review of the literature on correctional staff turnover

Correctional staff are the most important asset for any correctional agency. In fact, they are the heart and soul of any correctional organization. Many staff, however, voluntarily quit. The cost of this turnover is high for correctional organizations. Nonetheless, correctional staff turnover has generated only limited research. Moreover, there has been little direction in the correctional turn-over research. The different forms of turnover are discussed and the correctional staff turnover research is reviewed. A causal model for correctional staff voluntary turnover is developed and presented to guide future research. This article is a revision of a paper presented at the 1998 American Society of Criminology Annual meeting in Washington D. C. and my dissertation. The author would like to thank the anonymous reviewers for their comments and suggestions, as well as Janet Lambert, Ferris State University, for her assistance in editing and proofreading this article.     

Identifying risk factors in stalking: a review of current research

Stalking is a behaviour which can cause substantial damage to its victims, whether the perpetrator is violent or not. Victims face a range of risks including not only assault, but persistent or recurrent stalking and varying degrees of psychological and social damage. The responsibility for assessing and managing these risks often falls to the mental health professional, yet the emerging stalking risk assessment literature is at too early a stage to provide clinicians with empirically derived evidence upon which to base their clinical practice. This paper reviews existing research to identify those factors currently believed to be associated with increased risk of physical and sexual assault; with persistent and/or recurrent stalking; and, with psychological and social damage.     

Asian gangs in the United States: The current state of the research literature

Since the late 1980s, criminologists have been interestedin analyzing Asian gangs. Despite the rather sharp increasein books and articles published on the subject in the1990s, there appears to exist no consensus on the nature and etiologyof Asian gangs. This paper describes the current state ofresearch on Asian gangs and assesses whether or not thereis a dominant criminological theory on their cause. Itcompares and contrasts African American and Asian gangs,and closes with research and policy recommendations.     

Controlling lethal autonomous weapons systems: A typology of the position of states

This paper seeks to understand the potential for robust global control of lethal autonomous weapons systems (LAWS). The paper seeks to uncover the predominant views and trends in global decision-making about such weapons systems by way of observing the positions and preferences of States inhabiting the international system as a realistic modality of a more probable normative outcome. Through a thorough examination of publicly available positions of United Nations (UN) Member States, it establishes a typology of varying positions maintained by States and reveals the argumentative rationale for the major positions advanced. This typology results to be far from unified and is composed of the following categories: (1) States that support the prohibition of LAWS; (2) States that support the prohibition of LAWS, but do not support calls for an international ban treaty; (3) States that do not support (or oppose) the prohibition of LAWS; (4) States with “flexible” positions over the LAWS: oppose use or use under certain circumstances, but not the development and production; (5) States that expressed support for multilateral talks, but have not expressed a position on the prohibition or not of LAWS; and (6) States that have called for a legally binding instrument (or legal regulation) on LAWS (inclusive of both prohibitions and regulations). Regulation and human control emerge as factors that have significant value in the equation.     

Infanticide in Malaysia: two case reports and a review of literature

In a strict and conservative society like Malaysia, the number of cases of infanticide has continued to occur. The authors present two typical cases of infanticide in Malaysia. Case 1 concerned a body of a fully mature newborn fetus disposed in a rubbish bin. The head was traumatically amputated by the rubbish truck's compactor. The umbilical cord was still attached to the body, with no reddening around the insertion. The severed neck showed features consistent with post-mortem amputation. The significant finding was expanded crepitant lungs, which floated in water. The histology of the lungs showed expanded alveoli. It was concluded that the baby had been born alive, but no cause of death could be elicited. Case 2 concerned a decomposed mature newborn found in a scrub forest. The internal organs showed advanced putrefaction, the lungs being collapsed, congested, and hemorrhagic, typical of decomposed lungs. No conclusion could be made about the state of birth or the cause of death because of the putrefied state of the body. The two cases illustrate the typical cases and problems faced by pathologists locally and probably elsewhere in the world. Most of the bodies are found in a putrefied state. Pathologists have to ascertain not only maturity and live birth but also the cause of death, which may be very subtle or masked by putrefaction. The problems of diagnosis of live birth are discussed.     

University technology transfer in China: a literature review and taxonomy

The Chinese university system is one of the world’s largest academic research performers and technology transfer is one of the system’s central roles. Academic interest in Chinese university technology transfer in both the West and China has increased in parallel. This review aims to outline what is known and evaluate the state of research about university technology transfer in China. To be comprehensive, uniquely this review considers the relevant journal articles in both English and Chinese languages. The major themes and methodologies used by authors are identified. The evolution of the literature, particularly those in Chinese from general discussions often with minimal citations to more empirically rigorous studies is documented. It is also shown that the English and Chinese language literatures have little overlap in terms of citations, thereby indicating that the two research communities are still largely disconnected. It is found that the sources of data have remained quite limited and the quantitative research is based almost entirely upon government statistics collected for administrative purpose. The concluding discussion suggests possible avenues for future progress in terms of developing new data sources and increasing the cross-fertilization of two research communities.
