Are America’s public mass shooters unique? A comparative analysis of offenders in the United States and other countries

Public mass shooters are often assumed to be an exceptionally American problem, but little is known about what proportion of global offenders attack in the United States, or how America’s offenders compare to those in other countries. The present study offers the first quantitative analysis of all known offenders from 1966 to 2012 who attacked anywhere on the globe and killed a minimum of four victims. The results suggest that public mass shooters in the United States are significantly more likely to arm themselves with multiple weapons and attack at school and workplace settings, while offenders from other countries are more likely to strike at military sites. These differences may be partially attributable to America’s national gun culture and its particular set of social strains.     

Mental health in Canada: Are there any risky occupations and industries?

This study examined the role of occupations and industries in explaining differences among workers reporting poorer mental health in the Canadian workforce. It used data coming from a large representative sample of 77,377 workers engaged in 139 occupations and 95 industries. Logistic regression analysis was used to identify differences in the odds of reporting poorer mental health, adjusting for gender, age, education, marital status, and household income. Results identify ten occupations and nine industries at higher risk for workers reporting poorer mental health. The article concludes by highlighting implications for actors and policymakers and by specifying potential targets for intervention.     

Are the perpetrators of violence one and the same? Exploring the co-occurrence of perpetration of physical aggression in the United States

Important gaps exist in our understanding of aggressive behavior and the extent to which aggression involves one or more types of victims. This information is critical for determining the utility of integrated approaches for violence prevention versus continuation of independent efforts for reducing community violence, partner violence, and child maltreatment. To better understand the overlap in aggressive behaviors within the general population, the authors examine the co-occurrence of self-reports of physically striking strangers, acquaintances, intimate partners, and children among a nationally representative sample of 3,024 U.S. adults. The findings from this cross-sectional random digit dial telephone survey show that more than a third of the population reports engaging in at least one form of aggression and that, of these, a third had perpetrated violence against more than one type of victim. The percent of respondents who reported perpetrating violence against more than one type of victim range from 13% (percent of those striking a friend or acquaintance who also struck a child) to 34% (percent of those striking a friend or acquaintance who also struck a stranger). Furthermore, engaging in one type of aggression substantially increases the odds of engaging in another from 1.5 to 4 times. The findings suggest potential value in pursuing both integrated and independent approaches in research and prevention.     

Determining the sequence of intersecting gel pen and laser printed strokes — A comparative study

The relative chronological sequence of intersecting gel pen ink lines and laser printed marks has been determined using optical methods. The results were obtained by observing spectral reflection, relative sheen, skipping and gaps of gel pen ink strokes at the point of intersection. The intersections are observed under stereomicroscope and digital microscope. The effectiveness of both the optical instruments for sequence of the strokes has been compared. The sequence of intersecting lines (of same colour, different colours and where one of the strokes is darker) has been established.     

Are There Ethnic Differences in Levels of Psychopathy? A Meta-Analysis

Although considerable research on psychopathy has been conducted over the past 30 years, relatively few studies have examined key issues related to potential ethnic differences in this constellation of socially maladaptive personality traits. Given recent sociopolitical and scientific developments, an issue of considerable debate is whether Black individuals possess "more" traits of psychopathy than do Whites. To address this issue, a meta-analysis of differences between these groups' scores on the Psychopathy Checklist--Revised (PCL-R; Hare, 1991) was performed, using 21 studies (N = 8,890) of correctional, substance abuse, and psychiatric samples. Blacks exceeded Whites by an average of less than 1 point on the PCL-R total score. Effect sizes for core interpersonal and affective traits of psychopathy (Factor 1) were sufficiently homogeneous to clearly interpret, although other features manifested statistically significant heterogeneity. Our finding that Blacks and Whites do not meaningfully differ in their levels of core psychopathic traits is consistent with community-based findings for self-report measures of psychopathy and clinical diagnoses of antisocial personality disorder.     

Are we becoming more violent? A comparison of trends in violent and property offenses in Australia and Western Australia

This paper examines Australian and West Australian trends in robbery, assault, and burglary. Police figures are contrasted with the results of Australian victimization surveys. The limitations of Australian victimization surveys are discussed. The results of Australian victimization surveys are contrasted with the results of the National Crime Survey in the United States and the International Crime Victim Survey. When all the qualifications are considered, it is concluded that there has been a trend upward in burglary and robbery prevalence and that this upward trend occurred mainly in the 1980s. However, because there is little evidence of a concomitant rise in the assault rate, the increasing prevalence of robbery and burglary is interpreted as reflecting social phenomena that are associated with acquisitiveness rather than aggressiveness. Other evidence pertaining to the level of violence in Australia is considered and it is concluded that this is insufficient to allow a conclusion that we are, as a nation, becoming more violent.     

What does a digital forensics opinion look like? A comparative study of digital forensics and forensic science reporting practices

This study explores digital forensics (DF) reporting practices and compares the results with other forensic science disciplines. Forty reports were obtained from a quasi-experiment involving DF examiners, and a quantitative content analysis was performed to determine which conclusion types they applied and which content they included with relevance to the credibility of the reported results. A qualitative analysis was performed to examine the certainty expressions used in the conclusions. The results were compared to a study of eight forensic science disciplines performed by Bali et al. [24,26]. The results show that the DF examiners tend to present their conclusions either as Categorical conclusion or Strength of support (SoS) conclusion types and that they address source, activity, and offence level issues in their conclusions. The content analysis indicates deficiencies in DF reporting practices, and several of the challenges seem to be shared with other FS disciplines. The analysis of certainty expressions showed that a plethora of expressions was used, and that they lacked reference to an established framework. The results indicate that more research on DF evaluation and reporting practices is necessary and justifies a need for enhanced focus on quality control and peer review within the DF discipline.     

Are they different? A comparison of risk in Dangerous and Severe Personality Disordered and Personality Disordered hospitalized populations

Abstract

There has been considerable interest internationally in the assessment and treatment of individuals who have a severe personality disorder and who might pose a high risk of future recidivism. In the UK, the Dangerous and Severe Personality Disorder (DSPD) programme was initiated to deal with just this group. It is unclear, yet, whether those admitted to these services are different from those admitted to conventional personality disorder (PD) services. In the present study, 60 patients admitted to DSPD services, under DSPD criteria, were compared with 44 patients admitted to personality disordered (non-DSPD) services within the same high secure psychiatric hospital, on risk measures, including (1) an index of predicted future violence, (2) previous offending behaviour and (3) ‘pre-treatment’ levels of institutional risk-related behaviour. Results indicated that DSPD patients do pose a greater clinical and management risk, have a higher number of ‘pre-treatment’ risk-related behaviour, and have a greater number of convictions and imprisonments after age 18, relative to PD patients. The implications and limitations of these results are discussed.     

Are We Human? Edgework in Defiance of the Mundane and Measurable

Edgework can be a useful heuristic tool in producing counter-statements about Orthodox Criminology, where the measurable has arguably become more important than the meaningful. This paper focuses on the embodied experiential nexus of culture and crime in which criminology is taught, administered, and investigated. The Burkean framework of Dramatism is used to reveal how collective creative productions by students can provide insight into the political context of the contemporary criminology classroom. Through an analysis of instant ethnographies penned by participants of a flash mob I illustrate how the role of autonomy and responsibility are not resources that students readily draw upon to understand themselves in relation to the production of knowledge and social change. These observations support some of the concerns raised by Cultural Criminologist about the rise of administrative criminology. In the spirit of detournement, I argue that one way to facilitate student engagement with knowledge production differently is to invite them to experience moments of embodied transgressions.     

A comparative study on the concentrations of 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in head and pubic hair

In this study, the concentrations of 11-nor-Δ(9)-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in pubic, axillary and beard hair were measured and the correlation between the concentrations of THCCOOH in head and pubic hair from same cannabis users were evaluated. The papers on body hair analysis for THCCOOH were rarely found although police officers submit body hair as a complimentary specimen to forensic laboratories in case cannabis users had no hair. Head, pubic, axillary, and beard hair were collected. All hair samples were cut into 0.5mm segments and decontaminated with methanol, digested with 1 mL of 1M NaOH at 85 °C for 30 min and extracted in 2 mL of n-hexane:ethyl acetate (9:1) two times after adding 1 mL of 0.1N sodium acetate buffer (pH = 4.5) and 200 μL of acetic acid followed by derivatization with 50 μL of PFPA and 25 μL of PFPOH for 30 min at 70 °C. The extracts were analyzed using gas chromatography tandem mass spectrometry operating in negative chemical ionization mode (GC/MS/MS-NCI). We determined the concentrations of THCCOOH in both pubic and head hair. The concentrations of THCCOOH in pubic hair were higher than those in head hair. We also evaluated the concentrations of THCCOOH in body hair (pubic, axillary and beard hair) and head hair according to the positive/negative urine test results. There was no statistically significant difference in the concentrations of THCCOOH in head and body hair according to urine results.     

Illegal entrepreneurs: a comparative study of the liquor trade in Stockholm and New Orleans 1920–1940

The 1920s were a golden period for smuggling in Nordic waters, as systems of prohibition were established in Finland, Norway and Iceland, while in Sweden an intricate system of rationing was implemented in 1917. A comparative study of the illegal liquor trade in Stockholm and New Orleans shows that the actual methods of smuggling were similar in the two cities. Mother ships brought the cargo to a point outside territorial waters, where it was shifted to smaller boats. These brought the liquor in through the archipelago of Stockholm or the bayous of the Mississippi delta. The relative lack of corruption in Sweden did not limit the extent of the black market. According to contemporary estimates, the amount of smuggled liquor was about the same in the two cities. The kind of alcohol that was brought in was different, however, and the value of the trade higher in New Orleans. Also, the organization of the trade differed, in terms of ownership and distribution. In neither city did the illegal entrepreneurs appear to be very violent. The fact that the rate of violence was much higher in New Orleans, than in Stockholm, did not seem to affect their business methods.     

Are reality monitoring differences between truthful and deceptive autobiographical accounts affected by standardisation for word-count and the presence of others?

Although a number of methods have been proposed to control for word-count differences between truthful and deceptive accounts, there is no uniformity amongst researchers using the Reality Monitoring (RM) criteria as to when, why or how to standardise for word-count differences. Another factor that also has received little attention in the literature is whether the number of others present when a person is providing an account alters the lexical profile of accounts such that RM scores are affected. To investigate these issues, 62 autobiographical statements, 31 truthful and 31 deceptive, were generated under 3 conditions, no person present, 1 and 2 persons present, and were analysed before and after standardisation for word-count and duration. Results showed that the criteria successfully discriminated between truthful and deceptive accounts when no attempt to control for word-count was made and, to a lesser extent, when accounts were standardised for duration; however, they failed to discriminate after accounts had been standardised for length. The presence of others did not affect the ability to distinguish between truthful and deceptive accounts. The results highlight the difficulties involved in developing normative standardisation criteria which could be used in the field to classify individual or small numbers of cases.     

The impact of mining rights on the local communities in Limpopo Province, South Africa： A comparative study

The paper aims to give an account of the substance and support the development of community based organizations in balancing their interests against the interests of the mining industries. It further examines the issue of the protection of social and economic right in the context of the globalization of the activities of multinational mining and petroleum companies, as illustrated by different instances of increasing state withdrawal and with regard to specific African countries. In Africa, economic liberalization has been accompanied by a programmed redefining of the role of the state withdrawal from certain areas： planning, production and social reform, a reorientation of state intervention from certain other areas, redistribution, regulation and mediation etc, with a view of promoting a particular type of growth strategy based on promotion of private economic interests. This process has led to the delegitimation and weakening of states which were already characterized by fiscal crises, notably in countries under structural adjustment. While the process of reconceptualisation of the role of the state is not specific to Africa, its impact has been particularly significant with regard to the possibility of implementing developmental strategies designed to protect social and economic rights.     

Are women really difficult? Challenges and solutions in the care of women in secure services

Abstract

Concern about the approach to the care of women in secure hospitals led to radical Department of Health Guidance in 2002 and 2003. This paper explores the views and experience of senior clinicians and managers involved in delivering care through semi-structured interviews. The gendered nature of the therapeutic challenge and the complexity of the women in their care are both articulated as well as the extent to which respondents see themselves as having addressed clinical practice guidance. Service delivery is substantially informed by the ideas of relational security, attachment theory and the recovery model. Traditional concepts of security were considered unhelpful in the care of women. Reliance on respondents’ views as to the quality of care offered must remain limited in view of the continuing absence of corresponding clinical outcome data. However, their responses should inform amendments to current service organisation.     

End of life decisions and pregnant women: do pregnant women have the right to refuse life preserving medical treatment? A comparative study

In this article the practice of end of life decisions is applied to pregnant women. This is not an easy task as shown by the extensive case law and literature on the subject. The main conclusion of the article is that the pregnant woman's wishes should always be respected whatever the consequences for the foetus may be. Another position would unjustly sacrifice the woman's fundamental rights to bodily integrity and self-determination for the benefit of a non-person. The result is repeated in the situation where the woman is found to be incompetent or brain dead.
