Motivation for aggressive religious radicalization: Goal regulation theory and a personality × threat × affordance hypothesis
A new set of hypotheses is presented regarding the cause of aggressive religious radicalization (ARR). It is grounded in classic and contemporary theory of human motivation and goal regulation, together with recent empirical advances in personality, social, and neurophysiological psychology. We specify personality traits, threats, and group affordances that combine to divert normal motivational processes toward ARR. Conducive personality traits are oppositional, anxiety-prone, and identity-weak (i.e., morally bewildered). Conducive threats are those that arise from seemingly insurmountable external forces and frustrate effective goal regulation. Conducive affordances include opportunity for immediate and concrete engagement in active groups that are powered by conspiracy narratives, infused with cosmic significance, encouraging of moral violence, and sealed with religious unfalsifiability. We propose that ARR is rewarding because it can spur approach motivated states that mask vulnerability for people whose dispositions and circumstances would otherwise leave them mired in anxious distress.

Femicide & Murdered Women's Children: Which Future for These Children Orphans of a Living Parent?
To assess the prevalence of femicides in Italy over the last
three years and the potential long lasting effects of these traumatic events
for the children of a woman who dies a violent death.
The data used in this study come from an internet search for
the number of femicides occurring in Italy between 1(st) January, 2012 and
31(st) October, 2014.
The total number of femicides was 319; the average age of
murdered women was 47.50 ± 19.26. Cold arms in the form of sharp object -mostly
knives- have caused the death of 102/319 women; firearms were used in 87/319
cases; asphyxiation was the chosen method in 52/319 cases. About the place
where the femicides occurred, 209/319 were committed inside the victim's house.
Children of women who died a violent death were 417 with a total of 180 minors
in less than three years. A total of 52/417 children were witness to the
killing and, among these 30/52 were minors; in 18/417 cases, children were
murdered together with their mother and among these 9/18 were minors.
Long-term studies are needed to ascertain what happens to
these children, to understand what are the most appropriate psychological
treatments, the best decisions about the contact with their father and the best
placement for these children.

Circumstances and Outcomes of a Firearm Seizure Law: Marion County, Indiana, 2006–2013
Indiana statute allows police to seize firearms without a warrant if the officer believes a person meets the law's definition of “dangerous.”
Review of the use of this law in Marion County (Indianapolis), Indiana, showed that prosecutors filed petitions in court to retain weapons seized by police under this law 404 times between 2006 and 2013. Police removed weapons from people due to identification of a risk of suicide (68%) or violence (21%), or the presence of psychosis (16%). The firearm seizures occurred in the context of domestic disputes in 28% of cases and intoxication was noted in 26% of cases.
There were significant demographic differences in the circumstances of firearm seizures and the firearms seized. The seized firearms were retained by the court at the initial hearing in 63% of cases; this retention was closely linked to the defendant's failure to appear at the hearing. The court dismissed 29% of cases at the initial hearing, closely linked to the defendant's presence at the hearing. In subsequent hearings of cases not dismissed, the court ordered the destruction of the firearms in 72% of cases, all when the individual did not appear in court, and dismissed 24% of the cases, all when the individual was present at the hearing.
Overall, the Indiana law removed weapons from a small number of people, most of whom did not seek return of their weapons. The firearm seizure law thus functioned as a months-long cooling-off period for those who did seek the return of their guns.

No Effect of Unemployment on Intimate Partner-Related Femicide During the Financial Crisis: A Longitudinal Ecological Study in Spain
Spain’s financial crisis has been characterized by an
increase in unemployment. This increase could have produced an increase in
deaths of women due to intimate partner-related femicides (IPF). This study
aims to determine whether the increase in unemployment among both sexes in
different regions in Spain is related to an increase in the rates of IPF during
the current financial crisis period.
An ecological longitudinal study was carried out in Spain’s
17 regions. Two study periods were defined: pre-crisis period (2005–2007) and
crisis period (2008–2013). IPF rates adjusted by age and unemployment rates for
men and women were calculated. We fitted multilevel linear regression models in
which observations at level 1 were nested within regions according to a
repeated measurements design.
Rates of unemployment have progressively increased in Spain,
rising above 20 % from 2008 to 2013 in some regions. IPF rates decreased
in some regions during crisis period with respect to pre-crisis period. The
multilevel analysis does not support the existence of a significant
relationship between the increase in unemployment in men and women and the
decrease in IPF since 2008.
The increase in unemployment in men and women in Spain does
not appear to have an effect on IPF. The results of the multilevel analysis
discard the hypothesis that the increase in the rates of unemployment in women
and men are related to an increase in IPF rates.
The decline in IPF since 2008 might be interpreted as the
result of exposure to other factors such as the lower frequency of divorces in
recent years or the medium term effects of the integral protection measures of
the law on gender violence that began in 2005.

Is Tattooing a Risk Factor for Adolescents' Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan
Juvenile crime affects not only the victims of the crime but also the delinquents' future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents' criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide.
A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery.
From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents' high probability of committing crimes.

Gaps in Crisis Mental Health: Suicide and Homicide-Suicide
Gaps in crises of mental health emerge from poor distinction between the qualities of people who suicide and those who murder and then kill themselves. The role, if any, that substance use has in such lethal violence is an example of such a lack of distinction.
In this study, a sample of medical examiner investigative and toxicology reports from Los Angeles and Orange counties in California were available for analysis for 432 suicide cases and 193 homicide-suicide cases. This informed clearer toxicological and pharmacological distinction of suicide from homicide-suicide.

This informed clearer toxicological and pharmacological distinction of suicide from homicide-suicide.
- Blood alcohol levels were higher in persons committing suicide than in homicide-suicide perpetrators (p=.004).
- Homicide-suicide perpetrators had almost twice the level of stimulants in their system than people who suicide (p=.022) but did not have comparatively elevated levels of drugs or alcohol.
Predictors of suicide included the following:
- substance abuse history,
- high number of drugs in system,
- death inside a house,
- and legal impairment by alcohol.
Predictors of homicide-suicide included
- gunshot as the cause of death,
- female gender,
- domestic conflict,
- children living in the home,
- and prior arrest for substance abuse.

A Burning Question: Does Arson Increase When Local House Prices Decline?
We construct panel data on house prices and the determined cause of 4.8 million individual fires in the United States between 1986 and 2010 to test whether decreases in local housing market prices coincided with increases in arson. Since some insured homeowners may attempt to disguise the actual cause of fire as accidental, we also examine how decreases in local house prices are associated with changes in the total number of fires and the probability of determined causes of accidental fires. For the sample period, our results suggest that declines in local house prices coincided with increases in arson, the total number of fires, and the probability that fires were determined to occur due to arson and misuse. We provide further support for the existence of such an effect with empirical evidence that the relation between declines in house prices and arson is stronger in states that allow mortgage lender recourse.

Personality Disorders and Violence: What Is The Link?
Despite a well-documented association between personality disorders (PDs) and violence, the relationship between them is complicated by the high comorbidity of mental disorders, the heterogeneity of violence (particularly in regard to its motivation), and differing views regarding the way PDs are conceptualised and measured. In particular, it remains unclear whether there is a causal relationship between PDs and violence, and what the psychological mechanisms might be that mediate such a relationship. Here, a perspective on PD and violence is offered that views the relationship between them through the lenses of the Five Factor Model of personality and a quadripartite typology of violence. Evidence is reviewed suggesting that emotion dysregulation/impulsiveness, psychopathy, and delusional ideation conjointly contribute to the increased risk of violence shown by people with PD, and do so by contributing to a broad severity dimension of personality dysfunction. This view is consistent with the abandonment of personality disorder categories in the forthcoming eleventh edition of the International Classification of Diseases (ICD-11), where severity of personality disorder is defined in terms of the degree of harm to self and others.
Below: The quadripartite (2×2) violence typology. The intersection of impulsiveness (vs. control/premeditation) and affect (positive vs. negative) yields 4 distinct types of violence characterised by motives of excitement seeking and greed (both associated with positive affect) and revenge and self-defence (both associated with negative affect)
Below: A schematic overview of the suggested relationship between personality disorder (PD) and violence. General psychopathology (p) is subsumed by 3 factors, Externalizing, Internalizing and Thought Disorder but, as reported in [7], p is associated most strongly with Thought Disorder (indicated by a heavy arrow in the figure). Externalizing subsumes traits associated with both psychopathy and emotional impulsiveness, both of which contribute to severe PD and increase the risk for violence, particularly appetitive violence. Thought Disorder is shown as contributing independently to the risk of violence, and particularly of aversive violence. Also shown are contextual factors such as alcohol use that operate as proximal causal risk factors for violence in concert with distal personality factors

Clarifying the Link Between Childhood Abuse History and Psychopathic Traits in Adult Criminal Offenders
Childhood abuse is a risk factor for the development of externalizing characteristics and disorders, including antisocial personality disorder and psychopathy. However, the precise relationships between particular types of childhood maltreatment and subsequent antisocial and psychopathic traits remain unclear.
Using a large sample of incarcerated adult male criminal offenders (n = 183), the current study confirmed that:
These findings bolster and clarify the link between childhood maltreatment and antisocial behavior later in life.
Using a large sample of incarcerated adult male criminal offenders (n = 183), the current study confirmed that:
- severity of overall childhood maltreatment was linked to severity of both psychopathy and antisocial personality disorder in adulthood.
- Moreover, this relationship was particularly strong for physical abuse and the antisocial facet of psychopathy.
- Sexual abuse history was uniquely related to juvenile conduct disorder severity, rather than adult psychopathy or antisocial behaviors.
- Additionally, there was a significantly stronger relationship between childhood maltreatment and juvenile conduct disorder than between childhood maltreatment and ASPD or psychopathy.
These findings bolster and clarify the link between childhood maltreatment and antisocial behavior later in life.

The Rikers Island Hot Spotters: Defining the Needs of the Most Frequently Incarcerated
We used "hot spotting" to characterize the persons
most frequently admitted to the New York City jail system in 2013.
We used our Correctional Health Services electronic health
record to identify 800 patients admitted in 2013 who returned most since
November 2008. We compared them to a randomly selected control group of 800
others admitted in 2013, by using descriptive statistics and cross-tabulations,
including data through December 2014.
The frequently incarcerated individuals had a median of 21
incarcerations (median duration 11 days), representing 18 713 admissions and
$129 million in custody and health costs versus $38 million for the controls.
The frequently incarcerated were:
- significantly older (42 vs 35 years),
- and more likely to have serious mental illness (19% vs 8.5%)
- and homelessness (51.5% vs 14.7%) in their record.
- Significant substance use was highly prevalent (96.9% vs 55.6%).
- Most top criminal charges (88.7%) for the frequently incarcerated were misdemeanors; assault charges were less common (2.8% vs 10.4%).
Frequently incarcerated persons have chronic mental health
and substance use problems, their charges are generally minor, and
incarceration is costly. Tailored supportive housing is likely to be less
costly and improve outcomes.

The Effect of Temperature on Arson Incidence in Toronto, Ontario, Canada
Studies of crime and weather have largely excluded arson from empirical and theoretical consideration, yet weather could influence arson frequency over short time frames, influencing the motivation and activity of potential arsonists, as well as the physical possibility of fire ignition. This study aims to understand the role of weather on urban arson in order to determine its role in explaining short-term variations in arson frequency.
We use data reported to the Ontario Fire Marshall's office of arson events in the City of Toronto between 1996 and 2007 to estimate the effect of temperature, precipitation, wind conditions and air pressure on arson events while controlling for the effects of holidays, weekends and other calendar-related events.
We find that temperature has an independent association with daily arson frequency, as do precipitation and air pressure. In this study area, cold weather has a larger influence on arson frequency than hot weather. There is also some evidence that extremely hot and cold temperatures may be associated with lower day-time arson frequency, while night-time arson seems to have a simpler positive linear association with temperature.

Detection of Drugs in Nails (fingernails and toenails): Three Year Experience
Nails (fingernails and toenails) are made of keratin. As the nail grows, substances incorporate into the keratin fibers where they can be detected 3-6 months after use. Samples are collected by clipping of 2-3 mm of nail from all fingers (100 mg). We present drug testing results from 10,349 nail samples collected from high-risk cases during a 3-year period of time. Samples were analyzed by validated analytical methods. The initial testing was performed mostly using enzyme-linked immunosorbent assay, but by liquid chromatography-tandem mass spectrometry (LC-MS-MS) as well. Presumptive positive samples were subjected to confirmatory testing with sample preparation procedures including washing, pulverizing, digestion and extraction optimized for each drug class.
The total of 7,799 samples was analyzed for amphetamines. The concentrations ranged from 40 to 572,865 pg/mg (median, 100-3,687) for all amphetamine analytes.
Nail analyses have become a reliable way of determining the long-term use and abuse of drugs. Extraction techniques are simple and produce accurate and precise results. Sensitive analytical instrumentation, mainly LC-MS-MS, allows for detection of femtogram (10(-15) g) quantities of substances in nails. Samples were from a high-risk population, therefore the extraordinary positivity rate was observed.
