Fate and transport of fragmented and spherical microplastics in saturated gravel and quartz sand.

Microplastics in urban runoff undergo rapid fragmentation and accumulate in the soil, potentially endangering shallow groundwater. To improve the understanding of microplastic transport in groundwater, column experiments were performed to compare the transport behavior of fragmented microplastics (FMPs ∼1-µm diameter) and spherical microplastics (SMPs ∼1-, 10-, and 20-µm diameter) in natural gravel (medium and fine) and quartz sand (coarse and medium). Polystyrene microspheres were physically abraded with glass beads to mimic the rapid fragmentation process. The experiments were conducted at a constant flow rate of 1.50 m day-1 by injecting two pore volumes of SMPs and FMPs. Key findings indicate that SMPs showed higher breakthrough, compared to FMPs in natural gravel, possibly due to size exclusion of the larger SMPs. Interestingly, FMPs exhibited higher breakthrough in quartz sand, likely due to tumbling and their tendency to align with flow paths, while both sizes (larger and smaller relative to FMPs) of SMPs exhibited higher removal in quartz sand. Therefore, an effect due to shape and size was observed.

Effects of medicalization on case outcomes in transgender employment discrimination court decisions.

Some attorneys and legal scholars argue that medicalizing transgender plaintiffs (i.e., introducing plaintiff diagnoses and/or medical procedures) in discrimination cases will enhance favorable plaintiff outcomes. Research and theory linking biological essentialism (i.e., believing social groups reflect biologically-rooted, stable categories) to prejudice, however, suggests that medicalizing transgender plaintiffs might not help them win cases and might instead backfire and harm their case outcomes. To test these competing hypotheses, we coded all published cases involving alleged transgender discrimination (N = 124) from 1974 to 2021. Importantly, we addressed limitations of existing research that narrowly defined transgender plaintiff medicalization exclusively via diagnosis by documenting various other forms of medicalization beyond diagnosis. Contrary to legal scholars' claims and attorney intuitions, medicalization did not predict favorable outcomes for transgender plaintiffs. In fact, various forms of medicalization beyond diagnosis predicted negative plaintiff case outcomes. We discuss the implications of this research for informing scientific theory and legal practice.

Effects of COVID on Mandated Child Abuse Reporting Among Nurses: The Mediating Role of Compassion Fatigue.

Because COVID triggered elevated rates of child abuse, but diminished rates of child abuse reporting, we explored predictors of nurses' attitudes toward reporting suspected child abuse during the COVID pandemic. In particular, we expected that compassion fatigue and compassion satisfaction would mediate the effects of COVID-related stressors (i.e., exposure to COVID patient death and suffering; COVID-related family income loss; frequent direct care of COVID patients; and parental burnout) on nurses' negative attitudes toward reporting suspected child abuse. Employing chain-referral sampling, we recruited a sample of 244 registered nurses (83% White; 87% women). Supporting hypotheses, compassion fatigue mediated the effects of job-related COVID stressors (exposure to COVID patient death and suffering; COVID-related family income loss; and frequent direct care of COVID patients) on nurses' negative attitudes toward reporting suspected child abuse. In addition, among nurses who were also parents, nurses' self-reported parental burnout mediated the relation between compassion fatigue and negative attitudes toward reporting suspected child abuse. In addition, compassion satisfaction mediated the effect of nurses' parental burnout on nurses' negative attitudes toward reporting suspected child abuse.

Impact of Care-Recipient Health Conditions on Employed Caregiver Well-Being: Measure Development and Validation.

Purpose: The research was designed to help our understanding of the relationship between care-recipient health and caregiver well-being. Design: To achieve this goal, we followed the measurement development steps outlined by Hinkin. We began by identifying 18 care-recipient health conditions that encapsulated the breath of caregiver duties pertaining to specific recipient health conditions. Methods: Using a sample of n = 1696 employed caregivers, we then developed and empirically validated a research instrument that allows researchers and practitioners to (1) identify whether the caregiver was providing care to an individual who suffered from one or more of 18 health conditions and (2) quantify the demands imposed on the caregiver of caring for someone with this health issue. Results: Factor analysis identified four different constructs each of which measures the demands placed on the caregiver of caring for someone suffering from several closely related health conditions: problems with daily functioning, mental health problems, cardiovascular problems, and cancer/immune system issues.

Shock Teams: A Contemporary Review.

PURPOSE OF REVIEW: Cardiogenic shock (CS) is a time-sensitive and often fatal condition. To address this issue, many centers have developed multidisciplinary shock teams with a common goal of expediting the recognition and treatment of CS. In this review, we examine the mission, structure, implementation, and outcomes reported by these early shock teams. RECENT FINDINGS: To date, there have been four observational shock team analyses, each providing unique insight into the utility of the shock team. The limited available data supports that shock teams are associated with improved CS mortality. However, there is considerable operational heterogeneity among shock teams, and randomized data assessing their value and best practices in both local and regional care models are needed.

Have genetic targets for faecal pollution diagnostics and source tracking revolutionized water quality analysis yet?

The impacts of nucleic acid-based methods - such as PCR and sequencing - to detect and analyze indicators, genetic markers or molecular signatures of microbial faecal pollution in health-related water quality research were assessed by rigorous literature analysis. A wide range of application areas and study designs has been identified since the first application more than 30 years ago (>1100 publications). Given the consistency of methods and assessment types, we suggest defining this emerging part of science as a new discipline: genetic faecal pollution diagnostics (GFPD) in health-related microbial water quality analysis. Undoubtedly, GFPD has already revolutionized faecal pollution detection (i.e., traditional or alternative general faecal indicator/marker analysis) and microbial source tracking (i.e., host-associated faecal indicator/marker analysis), the current core applications. GFPD is also expanding to many other research areas, including infection and health risk assessment, evaluation of microbial water treatment, and support of wastewater surveillance. In addition, storage of DNA extracts allows for biobanking, which opens up new perspectives. The tools of GFPD can be combined with cultivation-based standardized faecal indicator enumeration, pathogen detection, and various environmental data types, in an integrated data analysis approach. This comprehensive meta-analysis provides the scientific status quo of this field, including trend analyses and literature statistics, outlining identified application areas, and discusses the benefits and challenges of nucleic acid-based analysis in GFPD.

An attribution theory-based content analysis of mock jurors' deliberations regarding coerced confessions.

OBJECTIVE: Because confessions are sometimes unreliable, it is important to understand how jurors evaluate confession evidence. We conducted a content analysis testing an attribution theory model for mock jurors' discussion of coerced confession evidence in determining verdicts. HYPOTHESES: We tested exploratory hypotheses regarding mock jurors' discussion of attributions and elements of the confession. We expected that jurors' prodefense statements, external attributions (attributing the confession to coercion), and uncontrollable attributions (attributing the confession to defendant naivety) would predict more prodefense than proprosecution case judgments. We also expected that being male, politically conservative, and in support of the death penalty would predict proprosecution statements and internal attributions, which in turn would predict guilty verdicts. METHOD: Mock jurors (N = 253, Mage = 47 years; 65% women; 88% White, 10% Black, 1% Hispanic, 1% listed "other") read a murder trial synopsis, watched an actual coerced false confession, completed case judgments, and deliberated in juries of up to 12 members. We videotaped, transcribed, and reliably coded deliberations. RESULTS: Most mock jurors (53%) rendered a guilty verdict. Participants made more prodefense than proprosecution statements, more external than internal attributions, and more internal than uncontrollable attributions. Participants infrequently mentioned various elements of the interrogation (police coercion, contamination, promises of leniency, interrogation length) and psychological consequences for the defendant. Proprosecution statements and internal attributions predicted proprosecution case judgments. Women made more prodefense and external attribution statements than men, which in turn predicted diminished guilt. Political conservatives and death penalty proponents made more proprosecution statements and internal attributions than their counterparts, respectively, which in turn predicted greater guilt. CONCLUSIONS: Some jurors identified coercive elements of a false confession and rendered external attributions for a defendant's false confession (attributing the confession to the coercive interrogation) during deliberation. However, many jurors made internal attributions, attributing a defendant's false confession to his guilt-attributions that predicted juror and jury inclinations to convict an innocent defendant.

When Disclosure Fails to Substantiate Abuse: Child and Perpetrator Race Predict Child Sexual Abuse Substantiation.

We examined the effects of child race, perpetrator race, and abuse disclosure status (within the context of a formal forensic interview) on abuse substantiation outcomes. Specifically, we coded child sexual abuse disclosure, abuse substantiation, and race of 315 children (80% girls, M age = 10, age range = 2-17; 75% White, 9% Black, 12% Biracial, 3% Hispanic, 1% Asian) who underwent a child forensic interview in a Midwestern child advocacy center. Supporting hypotheses, abuse substantiation was more likely in cases involving (a) abuse disclosure (vs. no disclosure), (b) White children (vs. children of color), and (c) perpetrators of color (vs. White perpetrators). Also supporting hypotheses, the effect of abuse disclosure on increased abuse substantiation was greater for White children than for children of color. This research suggests that even when children of color disclose their experiences of sexual abuse, they nonetheless face barriers to abuse substantiation.

A call to dismantle systemic racism in criminal legal systems.

OBJECTIVES: In October 2021, the American Psychological Association (APA) passed a resolution addressing ways psychologists could work to dismantle systemic racism in criminal legal systems. In the present report, developed to inform APA's policy resolution, we detail the scope of the problem and offer recommendations for policy makers and psychologists to address the issue by advancing related science and practice. Specifically, we acknowledge the roots of modern-day racial and ethnic disparities in rates of criminalization and punishment for people of color compared with White people. Next, we review existing theory and research that helps explain the underlying psychological mechanisms driving racial and ethnic disparities in criminal legal systems (e.g., endorsement of negative stereotypes, explicit and implicit bias). We also elucidate how racially disparate treatment generates downstream negative mental health consequences for people of color. CONCLUSIONS: Evidence-based recommendations to work toward eliminating systemic racism in the criminal legal systems include (a) rigorous measurement and analysis of disparities; (b) targeted changes in policy, practice, and law; (c) increased access to culturally aware and competent services and interventions; (d) design and promotion of education and training programs regarding racial bias; (e) increased attention to issues of intersectionality; and (f) promotion of diversity and fair-mindedness among criminal legal actors.

Transport and removal of spores of Bacillus subtilis in an alluvial gravel aquifer at varying flow rates and implications for setback distances.

To guarantee proper protection from fecally transmitted pathogen infections, drinking water wells should have a sufficiently large setback distance from potential sources of contamination, e.g. a nearby river. The aim of this study was to provide insight in regards to microbial contamination of groundwater under different flow velocities, which can vary over time due to changes in river stage, season or pumping rate. The effects of these changes, and how they affect removal parameters, are not completely understood. In this study, field tracer tests were carried out in a sandy gravel aquifer near Vienna, Austria to evaluate the ability of subsurface media to attenuate Bacillus subtilis spores, used as a surrogate for Cryptosporidium and Campylobacter. The hydraulic gradient between injection and extraction was controlled by changing the pumping rate (1, 10 l/s) of a pumping well at the test site, building upon previously published work in which tracer tests with a 5 l/s pumping rate were carried out. Attachment and detachment rate coefficients were determined using a HYDRUS-3D model and ranged from 0.12 to 0.76 and 0-0.0013 h-1, respectively. Setback distances were calculated based on the 60-day travel time, as well as a quantitative microbial risk assessment (QMRA) approach, which showed similar results at this site; around 700 m at the highest pumping rate. Removal rates (λ) in the field tests ranged from 0.2 to 0.3 log/m, with lower pumping rates leading to higher removal. It was shown that scale must be taken into consideration when determining λ for the calculation of safe setback distances.

COVID-19 patient care predicts nurses' parental burnout and child abuse: Mediating effects of compassion fatigue.

BACKGROUND: Nurses who are also parents may be at risk not only for professional compassion fatigue, but also parental burnout - a reliable and valid predictor of child abuse and neglect. In support, recent research reveals that parents' COVID-19 related stressors predicted elevated potential for child abuse (Katz and Fallon, 2021). OBJECTIVE: We explored the harmful effects of the COVID-19 pandemic on nurses' parental burnout, child abuse, and child neglect, as mediated by compassion fatigue (i.e., a combination of job burnout and secondary traumatic stress). PARTICIPANTS AND SETTING: Participants were 244 nurses (M age = 32.4; 87% female) who were parents of young children (age 12 or under) recruited via chain referral sampling. METHODS: Participants completed an anonymous survey assessing the extent to which they care for COVID-19 patients, are exposed to patients suffering and dying from COVID-19, and have lost family income due to COVID-19. We also measured their compassion fatigue, compassion satisfaction, substance abuse, spouse conflict, parental burnout, child abuse, and child neglect. RESULTS: As hypothesized, direct care of COVID-19 patients, exposure to patient death and suffering due to COVID-19, and family income loss due to COVID-19 predicted greater compassion fatigue, which in turn, predicted greater parental burnout, child abuse, child neglect, spouse conflict, and substance abuse, (IEs ≥ 0.06, all ps < 0.05). Also, as compassion satisfaction increased, parental burnout, child abuse, child neglect, spouse conflict, and substance abuse decreased, rs ≥ -0.203, ps < 0.01. CONCLUSIONS: Theoretical implications and practical implications for medical practice and child abuse prevention are discussed.

Effects of Intimate Partner Violence Perpetrator and Victim Race on Protective Order Determinations.

The legal granting of temporary and permanent protective orders prohibits a perpetrator from engaging in contact with the victim. Although protective orders reduce risk of re-abuse, very little research has explored factors that predict the likelihood that a victim is granted a protective order. Thus, we conducted an archival analysis on data previously collected from a Protection Order Assistance Office in a midwestern region of the United States, testing the influence of victim and perpetrator race on protective order allocations. Specifically, we coded data gathered from 490 petitioners (i.e., victims) seeking a protective order against a perpetrator of intimate partner violence, stalking, or sexual offending. Analyses revealed that racial minority victims were significantly less likely to receive a temporary protective order compared to White victims - effects that were exacerbated when the perpetrator was White (versus racial minority). These results are in line with existing research and theory regarding aversive racism. Implications for theory, policy, and practice are discussed.

Upscaling Transport of Bacillus subtilis Endospores and Coliphage phiX174 in Heterogeneous Porous Media from the Column to the Field Scale.

Groundwater contamination and transport of viruses and bacteria in aquifers are a major concern worldwide. To ascertain the ability of these aquifers to remove pathogens, tracer tests with microbial surrogates are carried out. These tests are laborious and may require special permits, and therefore, column tests are often done instead. Unfortunately, results from column tests tend to grossly overestimate removal rates when compared to the field scale, which can lead to an underestimation of groundwater contamination risks. Scale is an important consideration when examining pathogen transport through porous media, as pathogen removal is rarely a linear process. In this study, field tests were carried out with endospores of Bacillus subtilis and coliphage phiX174 over a distance of 25 m in an alluvial gravel aquifer near Vienna, Austria. The sandy gravel material from the field site was also used in column tests with the same tracers. Both attachment-detachment and colloid filtration theory were used to model these tests, as well as log-removal rates per meter. The results show that the spatial removal rate (log/m) is approximately 2 orders of magnitude higher on the column scale, when compared to the field. A comparison with the literature showed a correlation between the heterogeneity of the porous media and the difference in removal rates between the column and field scale.

Association between procedure appropriateness and patient-reported outcomes after percutaneous coronary intervention.

OBJECTIVE: The Appropriate Use Criteria (AUC) has been used to identify individuals who are likely to benefit from percutaneous coronary intervention (PCI) for stable ischaemic heart disease. However, whether physicians reliably grade PCI appropriateness and whether AUC categories stratify symptomatic improvement in real-world practice are unclear. METHODS: Patient-reported outcomes measures (PROMs) for angina (Seattle Angina Questionnaire (SAQ-7)), dyspnoea (Rose Dyspnea Scale (RDS)) and depression (Patient Health Questionnaire-2 (PHQ-2)) were collected on patients undergoing elective coronary angiography at an academic medical centre. Retrospectively, two physicians independently determined PCI appropriateness by the AUC criteria. RESULTS: Inter-rater agreement on appropriateness was moderate (κ=0.48, 95% CI 0.32 to 0.63). Of PCI procedures evaluated, 57 (47.1%) were appropriate (A-PCI), 62 (51.2%) were maybe appropriate (MA-PCI) and 2 (1.6%) were rarely appropriate. At baseline, A-PCI compared with MA-PCI patients had worse RDS scores (2.0 vs 1.2, p=0.01). At 30 days, the change in SAQ-7 summary score was similar between groups (A-PCI vs MA-PCI, +27.1 vs +20.7, p=0.11). The mean change in RDS score was greater in A-PCI than MA-PCI (-1.0 vs -0.5, p for group by time interaction=0.03). PHQ-2 scores were similar and did not improve at 30 days. CONCLUSION: In patients undergoing PCI with PROMs collected before and 30 days after PCI, similar improvements in angina were observed regardless of appropriateness. Inter-rater agreement on PCI appropriateness was only moderate. Use of PROMs may improve reliability of physician assessments of PCI appropriateness.

Sexual Abuse Disclosure Mediates the Effect of an Abuse Prevention Program on Substantiation.

Although abuse prevention programs have proliferated, little research has explored the direct effects of such programs on actual child sexual abuse disclosure rates, and no research has explored the effects of such programs on child sexual abuse substantiation. Employing a quasi-experimental design, the present research reflects an exploration of the effects of exposure to the Think First and Stay Safe™ abuse prevention program on abuse disclosure rates of 319 children who underwent a child forensic interview within 2015-2018 in a Midwestern child advocacy center. Supporting our mediational hypotheses, children exposed (vs. not exposed) to the Think First and Stay Safe™ program were significantly more likely to disclose abuse during the forensic interview, which in turn predicted significantly increased abuse substantiation likelihood.

Understanding how social worker compassion fatigue and years of experience shape custodial decisions.

BACKGROUND: Compassion fatigue (i.e., a worker's diminished ability to empathize with clients) is common among "helping workers" and can result in psychological detachment from clients as a coping mechanism. OBJECTIVE: In the present research, we explored the relationship between social workers' compassion fatigue and years of job experience on hypothetical child custody case judgments. PARTICIPANTS AND SETTING: In two separate studies, individuals with experience working with children in child dependency court (predominantly social workers, Study 1: N = 173, Study 2: N = 119) were recruited on Amazon's Mechanical Turk and read a vignette depicting a mother attempting to regain custody. RESULTS: Supporting hypotheses, compassion fatigue significantly mediated the relationship between increased years of social worker job experience on recommendations that a neglectful mother receive custody, Indirect Effect = .06, CIs [.026, .127] (Study 1). We also found preliminary support for our hypothesized theoretically derived serial path model, in which (a) social worker compassion fatigue predicts anticipated secondary traumatic stress associated with the child neglect case, B = .54, p =  .0001; (b) secondary traumatic stress predicts detachment from the neglected child, B = .27, p =  .0003; (c) detachment from the child predicts job efficacy cynicism B = .65, p <  .0001; and (d) job efficacy cynicism predicts decisions to allocate custody to the neglectful mother, B = .46, p =  .005 (Study 2). CONCLUSION: Our research shows that compassion fatigue among social workers may change the lens through which they perceive cases of child abuse.

Attachment and Detachment Behavior of Human Adenovirus and Surrogates in Fine Granular Limestone Aquifer Material.

The transport of human adenovirus, nanoparticles, and PRD1 and MS2 bacteriophages was tested in fine granular limestone aquifer material taken from a borehole at a managed aquifer recharge site in Adelaide, South Australia. Comparison of transport and removal of virus surrogates with the pathogenic virus is necessary to understand the differences between the virus and surrogate. Because experiments using pathogenic viruses cannot be done in the field, laboratory tests using flow-through soil columns were used. Results show that PRD1 is the most appropriate surrogate for adenovirus in an aquifer dominated by calcite material but not under high ionic strength or high pH conditions. It was also found that straining due to size and the charge of the colloid were not dominant removal mechanisms in this system. Implications of this study indicate that a certain surrogate may not represent a specific pathogen solely based on similar size, morphology, and/or surface charge. Moreover, if a particular surrogate is representative of a pathogen in one aquifer system, it may not be the most appropriate surrogate in another porous media system. This was apparent in the inferior performance of MS2 as a surrogate, which is commonly used in virus transport studies.

The Influence of a Juvenile's Abuse History on Support for Sex Offender Registration.

We investigated whether and how a juvenile's history of experiencing sexual abuse affects public perceptions of juvenile sex offenders in a series of 5 studies. When asked about juvenile sex offenders in an abstract manner (Studies 1 and 2), the more participants (community members and undergraduates) believed that a history of being sexually abused as a child causes later sexually abusive behavior, the less likely they were to support sex offender registration for juveniles. Yet when participants considered specific sexual offenses, a juvenile's history of sexual abuse was not considered to be a mitigating factor. This was true when participants considered a severe sexual offense (forced rape; Study 3 and Study 4) and a case involving less severe sexual offenses (i.e., statutory rape), when a juvenile's history of sexual abuse backfired and was used as an aggravating factor, increasing support for registering the offender (Study 3 and Study 5). Theoretical and practical implications of these results are discussed.

Explaining gender differences in jurors' reactions to child sexual assault cases.

In three experiments, we investigated the influence of juror, victim, and case factors on mock jurors' decisions in several types of child sexual assault cases (incest, day care, stranger abduction, and teacher-perpetrated abuse). We also validated and tested the ability of several scales measuring empathy for child victims, children's believability, and opposition to adult/child sex, to mediate the effect of jurors' gender on case judgments. Supporting a theoretical model derived from research on the perceived credibility of adult rape victims, women compared to men were more empathic toward child victims, more opposed to adult/child sex, more pro-women, and more inclined to believe children generally. In turn, women (versus men) made more pro-victim judgments in hypothetical abuse cases; that is, attitudes and empathy generally mediated this juror gender effect that is pervasive in this literature. The experiments also revealed that strength of case evidence is a powerful factor in determining judgments, and that teen victims (14 years old) are blamed more for sexual abuse than are younger children (5 years old), but that perceptions of 5 and 10 year olds are largely similar. Our last experiment illustrated that our findings of mediation generalize to a community member sample.
