The field of criminology is limited by a 'hidden' measurement crisis. It is hidden because scholars either are not aware of the shortcomings of their measures or have implicitly agreed that scales with certain properties merit publication. It is a crisis because the approaches used to construct measures do not employ modern systematic psychometric methods. As a result, the degree to which existing measures have methodological limitations is unknown. The purpose of this Element is to unmask this hidden crisis and provide a case study demonstrating how to build a measure of a prominent criminological construct through modern systematic psychometric methods. Using multiple surveys and item response theory, it develops a ten-item scale of procedural justice in policing. This can be used in primary research and to adjudicate existing measures. The goal is to reveal the nature of the field's measurement crisis and show a strategy for solving it.
Joseph Addison’s Cato (1713) is a play in the US-American bloodstream: it was quoted repeatedly by the architects of the American Revolution and was famously performed by Washington’s troops at Valley Forge in 1778. But what does this 300-year-old verse tragedy—with its entangled political, racial, and theatrical histories and implications—have to say to audiences in the present-day US South at the Clarence Brown Theatre, Tennessee, in 2023?
Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).
Aims
We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.
Method
Based on individual genotypes from case–control cohorts of BPD and MDD shared through the Psychiatric Genomics Consortium, we compile case–case–control cohorts, applying a careful quality control procedure. In a resulting cohort of 51 149 individuals (15 532 BPD patients, 12 920 MDD patients and 22 697 controls), we perform a variety of GWAS and PRS analyses.
Results
Although our GWAS is not well powered to identify genome-wide significant loci, we find significant chip heritability and demonstrate the ability of the resulting PRS to distinguish BPD from MDD, including BPD cases with depressive onset (BPD-D). We replicate our PRS findings in an independent Danish cohort (iPSYCH 2015, N = 25 966). We observe strong genetic correlation between our case–case GWAS and that of case–control BPD.
Conclusions
We find that MDD and BPD, including BPD-D are genetically distinct. Our findings support that controls, MDD and BPD patients primarily lie on a continuum of genetic risk. Future studies with larger and richer samples will likely yield a better understanding of these findings and enable the development of better genetic predictors distinguishing BPD and, importantly, BPD-D from MDD.
Metabolic and bariatric surgery (MBS) is safe and efficacious for adolescents with severe obesity. Pairing MBS with behavioral lifestyle interventions may be effective for optimizing treatment outcomes. However, no standardized program exists. Adolescent perspectives are critical to understanding how to design interventions to enhance engagement, sustain motivation, and meet informational needs for pre- and post-MBS self-management behaviors. The aim of this study was to develop an MBS lifestyle support intervention built on evidence-based content with input from adolescents and their families.
Methods:
A mixed-methods design identified adolescent preferences for MBS lifestyle support. Data were collected from a racially and ethnically diverse sample of adolescents (N = 17, 76% females, 24% males 41.2% non-Hispanic Black, 41.2% Hispanic/Latino, 11.8% non-Hispanic White, 5.8% Other) and their mothers (N = 13, 38.4% Hispanic) recruited from an MBS clinic. Quantitative surveys and qualitative interviews assessed preferred types of pre-post MBS content, modality, frequency, and delivery platforms to inform the design of the intervention. Mixed methods data were triangulated to provide a comprehensive understanding of adolescent/parent preferences.
Results:
Adolescents prioritized eating well, managing stress, and maintaining motivation as desired support strategies. Parents identified parental support groups and nutrition guidance as priorities. Peer support and social media platforms were identified as key approaches for boosting motivation and engagement.
Conclusions:
The patient voice is an important first step in understanding how, and whether behavioral lifestyle programs combined with MBS for weight management can be optimized. Adolescent preferences may enhance program fit and identify health behavior supports needed to sustain behavior change.
Bigotry distractions are strategic invocations of racism, transphobia, or negative stigma toward other marginalized groups to shape political discourse. Although the vast majority of Americans agree on large policy issues ranging from reducing air pollution to prosecuting corporate crime, bigotry distractions divert attention from areas of agreement toward divisive identity issues. This article explores how the nefarious targeting of identity groups through bigotry distractions may be the tallest barrier to health reform, and social change more broadly. The discussion extends the literature on dog whistles, strategic racism, and scapegoating.
Background: Carotid body tumours (CBT) are rare neoplasms of the paraganglia at the carotid bifurcation. Histopathologic analysis alone is insufficient to confirm malignancy, requiring metastases to non-neuroendocrine tissue including cervical lymph nodes for definitive diagnosis. The role of selective neck dissection (SND) during CBT surgeries in detecting malignancy and guiding subsequent management remains uncertain. Methods: A retrospective case series was performed on all patients undergoing CBT surgeries with SND between 2002 and 2022. Data collection included demographics, genetic and laboratory testing, imaging, intra- and post-operative complications, follow-up and histopathology. Results: Twenty-one patients underwent CBT resection with SND. Of these, 3 had carotid artery injuries, and 5 had nerve injuries. One patient experienced peri-operative embolic strokes, presumed related to tumour embolization. Three patients were found to have lymph node involvement, confirming malignancy. Malignancy was significantly associated with the risk of carotid injury (p = 0.04.) Conclusions: SND is a useful adjunct in detecting malignancy during CBT resection. The incidence of malignancy in CBT is low but not negligible and SND should be considered in patients with suspected malignancy or high-risk factors. This study’s 14% incidence of malignancy suggests there may be a rationale for considering universal implementation of SND during CBT resection.
With the efflorescence of palaeoscientific approaches to the past, historians have been confronted with a wealth of new evidence on both human and natural phenomena, from human disease and migration to landscape change and climate. These new data require a rewriting of our narratives of the past, questioning what constitutes an authoritative historical source and who is entitled to recount history to contemporary societies. Humanities-based historical inquiry must embrace this new evidence, but to do so historians need to engage with it critically, just as they do with textual and material sources. This article highlights the most vital methodological issues, ranging from the spatiotemporal scales and heterogeneity of the new evidence to the new roles attributed to quantitative methods and the place of scientific data in narrative construction. It considers areas of study where the palaeosciences have “intruded” into fields and subjects previously reserved for historians, especially socioeconomic, climate, and environmental history. The authors argue that active engagement with new approaches is urgently needed if historians want to contribute to our evolving understanding of the challenges of the Anthropocene.
Making woody mulch (WM) from organic waste is one solution for repurposing waste. Our work had two primary objectives. First, we wanted to destermine the current use of WM as a soil cover, barriers to use, benefits, and possible motivations for adopting the use of WM by home and commercial growers for cultivating crops in Barbados and the Baltimore-Washington, DC metropolitan region in the USA. To accomplish this objective, we administered a survey to growers in both regions. Second, we wanted to determine the benefits of using WM in agricultural production for sweet potatoes (both regions) and Hungarian hot wax peppers (USA). We measured whether WM influenced crop survival, crop yield, crop nutrients, weed mass, and soil characteristics in replicated plots covered with a layer of WM or left bare. Growers reported that expense, availability, and ease of application were barriers to using WM. Despite the barriers, many growers were using, or had previously used, WM and reported myriad benefits, including improving plant yield and/or nutrients, preventing weed growth, maintaining soil moisture and reducing irrigation needs, improving soil fertility, reducing soil erosion, reducing compaction from heavy rain, and maintaining soil temperature. Our data from replicated field trials verified some of the potential benefits reported by growers. WM in some cases promoted higher crop survival and yield of sweet potatoes, suppressed weeds, conserved soil moisture, and maintained higher soil temperature. Understanding which crops benefit from WM and the longer-term effects of WM on crops and soil are deserving of future study.
Background: Despite significant advances in the treatment of neurological disorders, many conditions remain palliative. Neurologists are in a unique position as they are integral in providing patient centered care, understanding neurologic disease and illness trajectory, and how disease can affect patients’ sense of self and values. Currently, little is known about neurologists’ perceptions and challenges in care planning and palliative care for their patients. Methods: A qualitative approach was utilized with semi-structured interviews of ten neurologists. Data was analyzed using a constant comparative method (constructivist grounded theory). Results: Participants represented a broad spectrum of neurologist experience and subspecialties. Four theories were identified: (1) care planning and palliative care are high priorities, (2) neurologic diseases uniquely affect patients and require a dynamic, patient-centered care plan, (3) a care gap exists in providing palliative care for neurologic patients with multifactorial barriers, and (4) opportunities to improve care exist with continuing education, collaboration, and health system support. Conclusions: Neurologists have a key role in care planning and palliative care for patients with chronic neurological diseases. Our findings show that there is a gap in the provision of palliative care. Future directions may include exploring educational opportunities and dedicated health systems to improve care management.
Russia’s annexation of Crimea in 2014, and the recent Russo-Ukrainian war that started in 2022, were triggers that radically changed the perception of security in the Nordic and Baltic countries. The on-going Russian hybrid war has resulted in a renewed global interest in the safety and security of many countries (eg, the Nordic-Baltic Eight). The prospective North Atlantic Treaty Organization (NATO) membership of Finland and Sweden may drastically change the regional military and political landscape.
The objective of this study was to identify and characterize all documented terrorist attacks in this region as reported to the Global Terrorism Database (GTD) from 1970 through 2020.
Methods:
The GTD was searched using the internal database functions for all terrorism incidents in the Nordic-Baltic states: Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, and Sweden.
Temporal factors, location, target type, attack and weapon type, perpetrator type, number of casualties, and property value loss were collated. Results were exported into an Excel spreadsheet for analysis.
Results:
There were 298 terrorism-related incidents from 1970 through 2020. Most attacks occurred in Sweden, followed by Norway and Finland. No entries were recorded for the Baltic states prior to their independency in 1991. The 298 incidents resulted in a total of 113 fatalities and 277 injuries.
Facility/infrastructure attacks were the most frequently identified attack type (35.0%), followed by bombings and explosions (30.9%). Armed assaults were responsible for 80 fatalities and 105 injuries, followed by bombings/explosions with 15 fatalities and 72 injuries. The predominant target types were immigrants and refugee shelters (64/298 incidents). In only 33.6% of the incidents, perpetrators were known. Right-wing assailants represented the largest group, accounting for 27 incidents.
Conclusion:
From 1970 through 2020, there were 298 terrorist attacks in the Nordic-Baltic Eight. Sweden accounted for 50% of incidents.
The profile of terrorist attacks was very diverse, as were the perpetrators and targets. Every country had its own incident characteristics. The surge of right-wing extremism must be closely monitored.
The on-going Russo-Ukrainian war has resulted in a renewed global interest in the safety and security of nuclear installations and the possibility of nuclear disasters caused by warfare and terrorism.
The objective of this study was to identify and characterize all documented terrorist attacks against nuclear transport, nuclear facilities, and nuclear scientists as reported to the Global Terrorism Database (GTD) over a 50-year period.
Methods:
The GTD was searched for all terrorist attacks against nuclear facilities, nuclear scientists, nuclear transport, and other nuclear industry-related targets in the period from 1970-2020. Analyses were performed on temporal factors, location, target type, attack and weapon type, perpetrator type, number of casualties, and property value loss.
Results:
Ninety-one incidents that occurred from 1970 through 2020 were included. Incidents took place in 25 countries and nine world regions, with most (42; 46.1%) occurring in Western Europe.
During these 50 years, 91 incidents resulted in 19 fatalities and 117 injuries. One perpetrator was killed during an incident and one other assailant was injured.
Bombings and explosions were the most frequently identified attack type (n = 40; 44.0%), followed by facility/infrastructure damage (n = 24; 26.4%) and armed assaults and assassinations (both n = 7; 7.7%).
Nuclear power plants and reactors under construction were targeted in 13 (14.3%) and eight (8.8%) incidents, respectively. Most of the attacks took place on other nuclear industry-related sites.
Conclusion:
Terrorist attacks carried out by non-state perpetrators against nuclear facilities, nuclear scientists, nuclear transport, and other nuclear industry-related targets are rare, with only 91 incidents in a 50-year period. None of the attacks resulted in radioactive fallout or environmental contamination. Most of the attacks took place outside a nuclear power plant.
The coronavirus disease 2019 (COVID-19) pandemic enabled a situational type of terrorism with mixed racist, anti-government, anti-science, anti-5G, and conspiracy theorist backgrounds and motives.
Objective:
The objective of this study was to identify and characterize all documented COVID-19-related terrorist attacks reported to the Global Terrorism Database (GTD) in 2020.
Methods:
The GTD was searched for all COVID-19-related terrorist attacks (aimed at patients, health care workers, and at all actors involved in pandemic containment response) that occurred world-wide in 2020. Analyses were performed on temporal factors, location, target type, attack and weapon type, attacker type, and number of casualties or hostages. Ambiguous incidents were excluded if there was doubt about whether they were exclusively acts of terrorism.
Results:
In total, 165 terrorist attacks were identified. With 50% of incidents, Western Europe was the most heavily hit region of the world. Nonetheless, most victims were listed in Southeast Asia (19 fatalities and seven injured). The most frequent but least lethal attack type concerned arson attacks against 5G telephone masts (105 incidents [60.9%] with only one injured). Armed assaults accounted for most fatalities, followed by assassinations. Incendiary and firearms were the most devastating weapon types.
Conclusion:
This analysis of the GTD, which identified 165 COVID-19-related terrorist attacks in 2020, demonstrates that the COVID-19 pandemic truly resulted in new threats for COVID-19 patients, aid workers, hospitals, and testing and quarantine centers. It is anticipated that vaccination centers have become a new target of COVID-19-related terrorism in 2021 and 2022.
Mass gatherings are vulnerable to terrorist attacks and are considered soft targets with potential to inflict high numbers of casualties. The objective of this study was to identify and characterize all documented terrorist attacks targeted at concerts and festivals reported to the Global Terrorism Database (GTD) over a 50-year period.
Methods:
The GTD was searched for all terrorist attacks against concerts and festivals that occurred world-wide from 1970 through 2019. Analyses were performed on temporal factors, location, target type, attack and weapon type, attacker type, and number of casualties or hostages. Ambiguous incidents were excluded if there was doubt about whether they were exclusively acts of terrorism. Chi-square tests were performed to evaluate trends over time and differences in attack types.
Results:
In total, 146 terrorist attacks were identified. In addition to musical concerts, festivals included religious, cultural, community, and food festivals. With 53 incidents, South Asia was the most heavily hit region of the world, followed by the Middle East & North Africa with 25 attacks. Bombings and explosions were the most common attack types. The attacks targeted attendees, pilgrims, politicians, or police/military members who secured the concerts and festivals.
Conclusion:
This analysis of the GTD, which identified terrorist attacks aimed at concerts and festivals over a 50-year period, demonstrates that the threat is significant, and not only in world regions where terrorism is more prevalent or local conflicts are going on. The findings of this study may help to create or enhance contingency plans.
Concerns that American psychiatry was neglecting an important dimension of human experience led to the introduction into DSM-IV of a V Code for a Religious or Spiritual Problem. The 1994 DSM-IV also included the new Outline for a Cultural Formulation, later accompanied by a Cultural Formulation Interview and 12 Supplemental Modules added to help clinicians to gather information for the Outline for Cultural Formulation. Recommendations from the APIRE Workgroup led to revisions in DSM-5, and outlined several areas for future research into the implications of spirituality, religion and culture for diagnosis and treatment. In particular, future research will need to better clarify the relationship between spiritual/religious and psychopathological phenomena, the different manifestations of psychiatric disorders in religious populations, the influences of spirituality/religion on the course and outcome of mental disorders, and the role of spirituality/religion in developmental and personality disorders.
There is emerging evidence of heterogeneity within treatment-resistance schizophrenia (TRS), with some people not responding to antipsychotic treatment from illness onset and a smaller group becoming treatment-resistant after an initial response period. It has been suggested that these groups have different aetiologies. Few studies have investigated socio-demographic and clinical differences between early and late onset of TRS.
Objectives
This study aims to investigate socio-demographic and clinical correlates of late-onset of TRS.
Methods
Using data from the electronic health records of the South London and Maudsley, we identified a cohort of people with TRS. Regression analyses were conducted to identify correlates of the length of treatment to TRS. Analysed predictors include gender, age, ethnicity, positive symptoms severity, problems with activities of daily living, psychiatric comorbidities, involuntary hospitalisation and treatment with long-acting injectable antipsychotics.
Results
We observed a continuum of the length of treatment until TRS presentation. Having severe hallucinations and delusions at treatment start was associated shorter duration of treatment until the presentation of TRS.
Conclusions
Our findings do not support a clear cut categorisation between early and late TRS, based on length of treatment until treatment resistance onset. More severe positive symptoms predict earlier onset of treatment resistance.

Avec l’efflorescence des approches paléoscientifiques du passé, les historiens ont été confrontés à une multitude de nouveaux indices sur des phénomènes tant humains que naturels, des maladies aux migrations en passant par les transformations du paysage et le climat. Ces données inédites exigent une réécriture des récits portant sur les périodes lointaines, remettant en cause à la fois les fondements de l’autorité des sources historiques traditionnelles et la légitimité des personnes habilitées à narrer le passé aux sociétés contemporaines. Les travaux d’histoire appuyés sur les sciences humaines doivent embrasser ces nouveaux types d’indices ; cependant, pour y parvenir, il est nécessaire pour les chercheurs de s’engager dans cette voie de manière critique, comme ils le font pour les sources textuelles et matérielles. Cet article souhaite mettre en lumière les questions méthodologiques les plus essentielles, qui vont des échelles spatio-temporelles et de l’hétérogénéité des nouvelles preuves au rôle à attribuer aux méthodes quantitatives et à la place des données scientifiques dans la construction narrative. Il examine les domaines d’étude où les paléosciences se sont « immiscées » dans des champs et des sujets auparavant réservés aux historiens, notamment l’histoire socio-économique, climatique et environnementale. Les auteurs soutiennent qu’il est urgent pour ces spécialistes d’explorer activement ces pistes novatrices, s’ils entendent contribuer à l’évolution de notre compréhension des défis de l’Anthropocène.
Response to lithium in patients with bipolar disorder is associated with clinical and transdiagnostic genetic factors. The predictive combination of these variables might help clinicians better predict which patients will respond to lithium treatment.
Aims
To use a combination of transdiagnostic genetic and clinical factors to predict lithium response in patients with bipolar disorder.
Method
This study utilised genetic and clinical data (n = 1034) collected as part of the International Consortium on Lithium Genetics (ConLi+Gen) project. Polygenic risk scores (PRS) were computed for schizophrenia and major depressive disorder, and then combined with clinical variables using a cross-validated machine-learning regression approach. Unimodal, multimodal and genetically stratified models were trained and validated using ridge, elastic net and random forest regression on 692 patients with bipolar disorder from ten study sites using leave-site-out cross-validation. All models were then tested on an independent test set of 342 patients. The best performing models were then tested in a classification framework.
Results
The best performing linear model explained 5.1% (P = 0.0001) of variance in lithium response and was composed of clinical variables, PRS variables and interaction terms between them. The best performing non-linear model used only clinical variables and explained 8.1% (P = 0.0001) of variance in lithium response. A priori genomic stratification improved non-linear model performance to 13.7% (P = 0.0001) and improved the binary classification of lithium response. This model stratified patients based on their meta-polygenic loadings for major depressive disorder and schizophrenia and was then trained using clinical data.
Conclusions
Using PRS to first stratify patients genetically and then train machine-learning models with clinical predictors led to large improvements in lithium response prediction. When used with other PRS and biological markers in the future this approach may help inform which patients are most likely to respond to lithium treatment.
Virtual reality (VR) has the potential to improve pain and pain-related symptoms. We examined the feasibility, acceptability, safety, and impact of a 30-min virtual underwater/sea environment (VR Blue) for reducing pain and pain-related symptoms in advanced colorectal cancer patients. A qualitative exit interview was conducted to understand preferences, thoughts, and feelings about the VR session.
Method
Participants (N = 20) had stage IV colorectal cancer and moderate-to-severe pain. Participants completed a 30-min VR Blue session that visually and aurally immersed them in virtual ocean scenarios. Feasibility was assessed by accrual (N = 20), protocol adherence (≥80% completing VR Blue), and completed data (≥80% assessment completion). Acceptability was determined by patients reporting ≥80% intervention satisfaction. Safety was determined by ≥80% of patients completing the session without self-reported side effects. Measures of pain, tension, relaxation, stress, anxiety, and mood were collected before, during, and after the VR Blue session. A semi-structured qualitative interview was conducted after VR Blue to assess participants’ VR experiences.
Results
All participants (100%) completed the VR Blue session. There was 100% data collection at the pre- and post-assessments. Satisfaction with VR Blue was high M = 3.3 (SD = 0.4) (83%). No significant side effects were reported. Pain decreased by 59% (Pre-M = 3 [1]; Post-M = 1 [1]). Tension decreased by 74% (Pre-M = 30 [24]; Post-M = 8 [13]). Relaxation improved by 38% (Pre-M = 62 [21]); Post-M = 86 [17]). Stress decreased by 68% (Pre-M = 24 [24]; Post-M = 8 [14]). Anxiety decreased by 65% (Pre-M = 20 [23]; Post-M = 7 [13]). Mood improved by 70% (Pre-M = 13 [16]; Post-M = 4 [11]). Qualitative data suggested a positive response to the VR Blue protocol.
Significance of results
This work supports the feasibility, acceptability, and safety of VR Blue for advanced colorectal cancer patients. Participants showed significant pre-post improvement in pain and pain-related symptoms hinting to the potential feasibility of VR interventions in this population. Larger, randomized trials with a control condition are needed to examine the efficacy of VR-based interventions for patients with advanced colorectal cancer and pain.
