Lithium in drinking water and the incidences of crimes,suicides, and arrests related to drug addictions

Using data for 27 Texas counties from 1978-1987, it is shown that the incidence rates of suicide, homicide, and rape are significantly higher in counties whose drinking water supplies contain little or no lithium than in counties with water lithium levels ranging from 70-170 micrograms/L; the differences remain statistically significant (p less than 0.01) after corrections for population density. The corresponding associations with the incidence rates of robbery, burglary, and theft were statistically significant with p less than 0.05. These results suggest that lithium has moderating effects on suicidal and violent criminal behavior at levels that may be encountered in municipal water supplies. Comparisons of drinking water lithium levels, in the respective Texas counties, with the incidences of arrests for possession of opium, cocaine, and their derivatives (morphine, heroin, and codeine) from 1981-1986 also produced statistically significant inverse associations, whereas no significant or consistent associations were observed with the reported arrest rates for possession of marijuana, driving under the influence of alcohol, and drunkenness. These results suggest that lithium at low dosage levels has a generally beneficial effect on human behavior, which may be associated with the functions of lithium as a nutritionally-essential trace element. Subject to confirmation by controlled experiments with high-risk populations, increasing the human lithium intakes by supplementation, or the lithiation of drinking water is suggested as a possible means of crime, suicide, and drug-dependency reduction at the individual and community level.     

Genomics and self-knowledge: implications for societal research and debate

Abstract

When the Human Genome Project (HGP) was launched, our genome was presented as our ‘blueprint’, a metaphor reflecting a genetic deterministic epistemology. Eventually, however, the HGP undermined rather than strengthened the understanding of genomes as blueprints and of genes as ultimate causal units. A symbolical turning point was the discovery that the human genome only contains～22,500 genes. Initially, this was seen as a narcissistic offence. Gradually, however, it strengthened the shift from traditional genetics and biotechnology (i.e., gene-oriented approaches) to genomics, i.e. genome-oriented or systems approaches, emphasizing complexity. The 20th century can be regarded as the century of biotechnology and of the gene. Its history demonstrated that the will to know (notably: to know ourselves) has never been a disinterested affair: it is driven by a will to improve (notably: to improve ourselves). In this article it is claimed that, as genomics takes us beyond a genetic deterministic understanding of life, this must have consequences for societal research and debate as well. Policies for self-improvement will increasingly rely on the use of complex interpretation. Therefore, the emphasis must shift from issues such as genetic manipulation and human enhancement to issues involved in governance of novel forms of information.     

Homelessness and dog ownership: an investigation into animal empathy,attachment, crime,drug use,health and public opinion

Abstract

A sample of 51 homeless people in Cambridge, UK completed a questionnaire featuring adapted Animal Empathy and Companion Animal Bonding Scales. Concepts of crime, drug use, and health matters amongst the homeless, both dog owning and non-dog owning, were investigated, as well. Ninety members of the general public completed a similar questionnaire which sought their opinions on homeless people who own dogs. There was a highly significant difference (p < 0.01) between the homeless and the securely housed on their animal empathy and attachment scores, with the homeless sample displaying higher values. Gender and dog ownership status had no effect on these scores. A near significant result (U = 2, n₁ = 13, n₂ = 58, p = 0.06) was revealed for animal empathy scores of those who gave money to dog-owning homeless people and those who gave to non-dog owning homeless people. Of the public respondents, women were significantly more likely to show concern for a homeless person's dog's welfare than men (X²₍₁₎ = 8.5, p < 0.01), and of the homeless respondents, non-dog owners were significantly more likely than dog owners to believe that having a dog helped initiate conversations with the public (X²₍₁₎ = 4.0, p < 0.05). Highly significant differences (U = 10, n₁ = 31, n₂ = 20, p < 0.01) were found for medical care use between the dog-owning and non-dog owning homeless, and health scores showed a reversed trend compared to that expected for the general population, with dog owners scoring lower than non-dog owners.     

German government investigates anti-Semitism

Anti-Semitism in Germany has a long tradition. It dates back to religious anti-Semitism many centuries ago culminating in the Holocaust. More recently, anti-Semitism was rising again in Germany. At least partly, it was encouraged by recent news reports on the Israel-Palestine conflict. This occurred at the time when a new Anti-Semitic party – the Alternative for Germany – emerged at Germany's political scene. To ascertain the prevalence of anti-Semitism, Germany's federal parliament set up an independent commission in 2012. In 2017, the commission reported its findings. This review discusses the commission's results focusing on a definition of anti-Semitism; hate crimes based on anti-Semitism; the extend of anti-Semitism in Germany's political centre; anti-Semitism in the media, social movements and racist organizations; an evaluation of anti-Semitism based on surveys and interviews; anti-Semitism in Germany's political parties; and finally, anti-Semitism of refugees and migrants. The report concludes recommendations seeking to prevent anti-Semitism.     

Blow fly artifacts from blood and putrefaction fluid on various surfaces: a source for forensic STR typing

Adult blow flies can deposit small spots (‘artifacts’) containing biological fluids like blood on various surfaces at a crime scene, either by regurgitation or defecation, and thereby create new or modify existing stains. These minute traces may represent evidence for the past presence of a certain person or victim in crime scene scenarios where nobody is present or all other crime‐related biological traces have been cleaned up. We analyzed artifacts on crime scene relevant surfaces (glass, wood, concrete, wallpaper, carpet, plastic wrap), produced by the forensically important blow fly Calliphora vicina Robineau‐Desvoidy (Diptera: Calliphoridae) after ingesting fresh and degraded porcine blood as well as putrefaction fluid from a pig's trotter and evaluated the potential of these spots for short tandem repeat (STR) analysis at various time intervals after deposition. Genotyping was possible on single fly artifacts on all surfaces up to 300 days after deposition by the flies after both blood or putrefaction fluid intake. The results indicate that the suitability for STR typing of those spots mainly depends on the time since deposition. The activity of flies at a crime scene can lead to artifacts which are – even 300 days after deposition – a valuable source of case‐related DNA. Sometimes those traces may even be the only source of information for DNA profiling.     

COVID‐19 lockdown frees wildlife to roam but increases poaching threats in Nepal

To contain transmission of COVID‐19, lockdowns or strict restrictions of people''s mobility outside their residences were instituted in a majority of countries worldwide, including Nepal, where the first phase of nationwide lockdown was observed from 24 March to 21 July 2020. This sudden halt in human outdoor activities brought positive and negative impacts on forests and wildlife. We undertook a study to learn the impact of the COVID‐19 lockdown on wildlife and forests in the protected areas (PAs) of Nepal. Between July and September 2020, data on illegal activities recorded by the staff of PAs and also those reported by media were collected and analyzed. Key informant interviews (KII) were done with the park officers and security personnel by virtual communication (telephone, messenger app, and video call) to collect detailed information and for corroboration. The collected data were categorized into four groups: (a) wildlife killed, (b) wildlife injured, (c) arrest incidents related to forest crime, and (d) arrest incidents related to wildlife crime. Data from the fiscal year 2019–2020 were analyzed, comparing before lockdown and after. Among 20 PAs investigated during the lockdown, the study found substantial increases in wildlife death in two PAs, Banke National Park, and Bardia National Park. Similarly, Chitwan National Park (CNP) and Shivapuri Nagarjun National Park (SNNP) witnessed a rise in wildlife poaching. CNP and SNNP are located close to densely populated cities and also have human settlements in their peripheries. Wildlife was sighted freely roaming inside PAs during the lockdown, presumably because the absence of visitors and human activities during the lockdown decreased disturbance. Thus, the wildlife was enjoying the freedom of movement on the one hand, and on the other hand was threatened by poachers, many of whom were laid off from other activities and were taking advantage of the lapse in security.     

Neighborhood safety, collective efficacy, and obesity in women with young children

Objective : To test the hypothesis that mothers of young children would have a higher prevalence of obesity if they lived in neighborhoods that they perceived as unsafe or as having a low level of collective efficacy. Research Methods and Procedures : Using data from the Fragile Families and Child Wellbeing Study, a cross‐sectional analysis was conducted of 2445 women living in 20 large (population ≥ 200, 000) U.S. cities. BMI was measured on 72% and self‐reported on 28%. Perception of neighborhood safety was assessed with the Neighborhood Environment for Children Rating Scales. The collective efficacy measure was adapted from the Project on Human Development in Chicago Neighborhoods. Results : Thirty percent of the women were married, 38% lived below the U.S. poverty threshold, and 66% reported no education beyond high school. Approximately one‐half of the women were non‐Hispanic black, and one‐fourth were Hispanic (any race). After adjustment for sociodemographic factors (household income, education, race/ethnicity, age, and marital status), smoking, depression, and television time, the prevalence of obesity (BMI ≥ 30 kg/m²) increased across tertiles of neighborhood safety from safest to least safe (37% vs. 41% vs. 46%, p = 0.004) but did not differ across tertiles of collective efficacy from highest to lowest (41% vs. 40% vs. 42%, p = 0.67). Discussion : In a national sample of women with young children, obesity was more prevalent among those who perceived their neighborhoods to be unsafe.     

Genes,environment and responsibility for violent behavior: “Whatever genes one has it is preferable that you are prevented from going around stabbing people”

For the legal system to function effectively people are generally viewed as autonomous actors able to exercise choice and responsible for their actions. It is conceivable that genetic traits associated with violent and antisocial behavior could call into question an affected individual's responsibility for acts of criminal violence. Evidence concerning genes associated with violent and antisocial behavior has been introduced in criminal courts in the USA and Italy, either alone or with associated environmental factors. One example of a “genetic defense” is based on low levels of monoamine oxidase A (MAOA) activity, with a prevalence of around 30% in Caucasian males. In countries with trial by jury it is particularly relevant to consider the views of publics on criminal liability and the significance they assign to evidence citing genetic influences on behavior. This article draws on largely qualitative research looking at participants' explanations of, and assigning of responsibility for, violent and antisocial behavior where environmental or genetic influences are claimed. Genetic factors were not viewed deterministically by participants but were considered by most to be irrelevant to personal responsibility. Notions of human agency, free will and choice were crucial to explanations of problem behaviors and ensured that offenders could be held responsible despite evidence on environmental and genetic factors.     

Visibilities,invisibilities and twilight zones at the crime scene in Portugal

The Police are the first element of a chain of custody culminating in the court. The documents they produce mediate the understandings between the crime scene and the court. Based on the formal rules, the police give visibility to the narrative and assign legitimacy and credibility to their performance. However, the decision to turn certain aspects of the narrative visible, leaving others in a twilight zone may have repercussions in the production of a verdict. Based in a qualitative analysis of three Portuguese judicial proceedings in this paper I explore how the narrative constructed by the police, based on what they see and what is unseen, travels between subepistemic cultures. Looking at the visibilities, invisibilities and twilight zones, I will try to understand how police forces at the crime scene in Portugal construct their narratives through the use of biological traces and how these narratives are part of the construction of the evidence. I argue that in criminal investigations in Portugal, the production of a narrative with legal meaning in court can be conditioned by the co-existence of the epistemic subcultures of police work (different police forces at the crime scene) that have different knowledge, practices, understandings and ways of “seeing” the forensic evidence. The degree of technological enthusiasm that guides the performance of different police forces at the crime scene is reflected in the way they “see” the scene and in the sociocultural understandings that they produce. This technological enthusiasm and what I call here “selective professional vision” are mobilized at the crime scene and can impact the robustness and efficiency of the evidence presented in court.
