Project Abstract: an Anglo-American intelligence operation in 1947 to recover guided weapon technical documentation buried in Germany

In early 1947, American intelligence organisations learned that there were hidden collections of technical documentation that pertained to World War II German guided weapon development that were not recovered by Allied investigators in 1945. A joint Anglo-American intelligence operation was initiated in February of that year, dubbed ‘Project Abstract’ by the Americans, to recover the caches. Project Abstract was a concerted effort by British and American scientific and technical intelligence experts to round up the last material remains of the World War II guided weapon programmes at the renowned experimental and testing establishments at Peenemünde in northern Germany.

Muscle contraction during electro-muscular incapacitation: A comparison between square-wave pulses and the TASER(®) X26 Electronic control device

Abstract: Electronic control devices (including the Advanced TASER^® X26 model produced by TASER International) incapacitate individuals by causing muscle contractions. To provide information relevant to development of future potential devices, effects of monophasic square waves with different parameters were compared with those of the X26 electronic control device, using two animal models (frogs and swine). Pulse power, electrical pulse charge, pulse duration, and pulse repetition frequency affected muscle contraction. There was no difference in the charge required, between the square waveform and the X26 waveform, to cause approximately the same muscle‐contraction response (in terms of the strength‐duration curve). Thus, on the basis of these initial studies, the detailed shape of a waveform may not be important in terms of generating electro‐muscular incapacitation. More detailed studies, however, may be required to thoroughly test all potential waveforms to be considered for future use in ECDs.     

Factors associated with escalation and problematic approaches toward public figures

Detailed comparison of factors associated with abnormal approach to the prominent and with escalation from communication to approach has not hitherto been undertaken. This partially reflects the failure of individual studies to adopt compatible terminologies. This study involves a careful dissection of six public figure studies, three involving U.S. politicians, two Hollywood celebrities, and one the British Royal Family. Common findings were unearthed across six headings. Approachers were significantly more likely to exhibit serious mental illness, engage in multiple means of communication, involve multiple contacts/targets, and to incorporate into their communication requests for help. They were significantly less likely to use threatening or antagonistic language in their communications, except in those cases involving security breaches. These results emphasize the importance of integrating mental health findings and preventive measures into risk management. Approach should not be regarded as a single behavioral category and has multiple motivations. Future studies should adopt standard terminology, preferably taken from the general stalking research.     

The Severe 5%: A Latent Class Analysis of the Externalizing Behavior Spectrum in the United States

Objective

Criminological research consistently demonstrates that approximately 5% of study populations are comprised of pathological offenders who account for a preponderance of antisocial behavior and violent crime. Unfortunately, there have been no nationally representative epidemiological studies characterizing the severe 5% group.

Materials and Methods

Data from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of 43,093 non-institutionalized U.S. residents aged 18 years and older were analyzed using latent class analysis to assess sociodemographic, psychiatric, and behavioral characteristics.

Results

Four-classes of respondents were identified vis-à-vis lifetime externalizing behaviors. A normative class (66.1% of respondents) demonstrated little involvement in antisocial conduct. A low substance use/high antisocial behavior class (20.7% of respondents) and high substance use/moderate antisocial behavior (8.0% of respondents) class evinced diverse externalizing and psychiatric symptoms. Finally, a severe class (5.3% of respondents) was characterized by pathological involvement in more varied and intensive forms of antisocial and externalizing behaviors and extensive psychiatric disturbance.

Conclusions

The current study is the first nationally representative epidemiological study of criminal careers/externalizing behavior spectrum in the United States and validates the existence of the 5% pathological group demonstrated by prior research.     

Predictors of suicidal ideation, suicide attempts, and self-harm without lethal intent in a community corrections sample

Purpose

Little published research data exist about suicidal ideation and self-harm behavior in community corrections and we seek to fill this void.

Aims

To examine the effects of drug dependence, depression, anxiety, psychopathy, fracture, and child trauma on suicidal ideation, suicide attempts, and self-harm without lethal intent in community corrections.

Methods

The Semi-Structured Assessment for the Genetics of Alcoholism Revised (SSAGA II) and the screening version of the Hare Psychopathy Checklist (PCL:SV) were administered. Separate binary logistic regression analyses were used to predict lifetime suicidal ideation, suicide attempt, and self-harm behavior.

Results

Prevalences of suicidal ideation, suicide attempt, and self-harm without lethal intent were 41%, 19%, and 14%. Suicidal ideation was predicted by drug dependence, elevated PCL:SV Factor 2 score, and Caucasian race. Suicidal ideation and attempt were both predicted by fractures, depression, and child trauma. Self-harm was predicted by fractures, panic, PCL:SV score, and child trauma.

Conclusions

Child trauma and multiple fractures are potent predictors for suicidal ideation, suicide attempts, and self-harm without lethal intent in this community corrections sample. Depression predicted suicidal ideation and attempts, while panic predicted self-harm without lethal intent. Psychopathy was also an important predictor of suicidal ideation and self-harm behaviors without lethal intent.     

Handle with care: engaging with faith-based organisations in development

Religious faith has always had an intense but uneasy relationship with development. Donors are currently seeking greater engagement with faith-based organisations (FBOs). This positive shift needs careful consideration. Faith can be a powerful – but flammable – fuel for change. FBOs are highly diverse and complex. Donors therefore need to handle them with understanding and care. This article outlines both the major concerns about faith in development and also the potential ‘value-added’ of FBOs. It charts growing interest yet residual ambivalence on the part of donors towards faith in development. It presents the practical challenges and suggests ways forward for both donors and FBOs.     

Evaluation of age estimation technique: testing traits of the acetabulum to estimate age at death in adult males

This study evaluates the accuracy and precision of a skeletal age estimation method, using the acetabulum of 100 male ossa coxae from the Grant Collection (GRO) at the University of Toronto, Canada. Age at death was obtained using Bayesian inference and a computational application (IDADE2) that requires a reference population, close in geographic and temporal distribution to the target case, to calibrate age ranges from scores generated by the technique. The inaccuracy of this method is 8 years. The direction of bias indicates the acetabulum technique tends to underestimate age. The categories 46-65 and 76-90 years exhibit the smallest inaccuracy (0.2), suggesting that this method may be appropriate for individuals over 40 years. Eighty-three percent of age estimates were ±12 years of known age; 79% were ±10 years of known age; and 62% were ±5 years of known age. Identifying a suitable reference population is the most significant limitation of this technique for forensic applications.     

Survival of anesthetized Sus scrofa after cycling (7-second on/3-second off) exposures to an electronic control device for 3 minutes

Electronic control devices (ECDs) may eventually be deployed by the military in a manner resulting in longer exposures than those encountered during law-enforcement operations. In a previous study, 18 repeated cycling (5-second on/5-second off) exposures (within a 3-minute period) of anesthetized swine to an ECD (TASER International's Advanced TASER X26 device) resulted in leg muscle contraction, acidosis, and increases in blood electrolytes. In the current study, experiments were performed to examine effects of exposures to a different cycling rate (7-second on/3-second off), from a modified X26 ECD, on 10 swine (Sus scrofa), maintained on propofol anesthesia. In contrast with the previous study, a large number of animals (6/10) died immediately after the exposures. There were no major differences in pre-exposure blood factors from survivors versus nonsurvivors, with the exception of hematocrit and 2 isoenzymes of lactate dehydrogenase. It is doubtful that these factors would be useful in predicting survival after ECD exposure. Blood pH was significantly decreased after exposure, but (in animals that survived) subsequently returned to baseline levels. On the basis of the overall survival rate, further development of useful ECDs (for long-term incapacitation during military operations) may require consideration of longer pauses between repeated exposures over a 3-minute period.
