Paediatric fatty liver disease (FLD) can develop into steatohepatitis, cirrhosis and hepatocellular carcinoma in adulthood. We assessed if early life physical exercise reduced the effects of high-fat (HF) diet-induced steatosis. Male HF-fed rats with access to a running wheel from weaning until day (D)60 (early exercise) or from D67 to D120 (late exercise) were compared with control HF- or chow-fed groups with no wheel. At D63 and D120, liver histopathology (Kleiner score), type I collagen and plasma enzymes were assessed. At D63, early life activity significantly reduced histopathology scores (total, portal inflammation, steatosis, ballooning, but not lobular inflammation or fibrosis) and the number of rats affected. At D120, HF control scores were higher than in chow-fed controls, but the effect of activity was selective: early exercise reduced portal inflammation, steatosis, ballooning and fibrosis, but late activity affected only portal inflammation and ballooning. The chow-fed portal inflammation score was significantly less than all HF groups, but lobular inflammation was lower in the HF control group only. The fibrosis score in the HF early exercise and control chow group were lower than in the late exercise and sedentary HF groups, indicating that early life exercise was more effective than when activity was introduced later in life. Plasma biomarkers showed minor between-group differences. The retained effect on liver histopathology rat at D120 after only early life exposure activity suggests that timing of introduction of exercise is critical in reducing FLD scores and prevalence in children, young adults and possibly into adulthood.

Parioxys ferricolus Cope, 1878 is a long-neglected taxon of dissorophid temnospondyls from the early Permian (Cisuralian) of Texas. Reexamination of the original material and preparation of a previously undescribed specimen shed some light on the ontogeny and reveal numerous eucacopine features. P. ferricolus is characterized by: (1) a preorbital region 1.5 times as long as the posterior skull table in juveniles and twice as long in adults, (2) a parietal only two-thirds the length of the frontal, (3) interpterygoid vacuities shorter than half the skull length, (4) choanae posteriorly extended, and (5) vomer with enlarged, V-shaped median depression. P. ferricolus is found nested with Kamacops acervalis Gubin, 1980, with which it shares synapomorphies in the palate, within the dissorophid clade Eucacopinae.

In 2019, we launched the Northern Arizona Paleoindian Project to expand on findings from the Rock Art Ranch (RAR) Research Experiences for Undergraduates (REU; NSF#1262184). The REU recovered 24 Paleoindian artifacts in association with drainages. Expansion of the research required mitigation of the patchwork landownership in the area, which encouraged a collector-collaboration model following Pitblado (2014) and Douglass et alia (2017). We held public events in collaboration with a network of agencies, avocational groups, collectors, and landowners to assess potential for Paleoindian archaeology in the area. In March 2020, however, the COVID-19 pandemic halted our efforts, allowing us to evaluate our project and practice. We find that tapping into existing local networks of responsible resource stewards (RRS) can greatly accelerate project development. We also find that private collections are endangered, and preserving this portion of the archaeological record requires documentation and long-term curation. Most importantly, we find that archaeologists working with collectors are uniquely positioned to build bridges between Indigenous communities, RRS, and professional archaeologists to help stabilize legacy collections and that this focus should drive collector-collaboration research design. Ultimately, the project must move toward a community-based participatory research design to seek equitable and culturally appropriate curation plans for local legacy collections.

A new taxon of sphenodontian reptile, Micromenodon pitti new genus new species is described from the Upper Triassic (Carnian) Vinita Formation of the Richmond basin of the Newark Supergroup in Virginia. It is diagnosed by a dorsoventrally deep facial process of the maxilla that extends for almost the entire anteroposterior length of the bone and by obtusely conical, strongly ribbed additional teeth in the maxilla that comprise a greatly enlarged tooth followed by smaller teeth posteriorly. Phylogenetic analysis found Micromenodon pitti n. gen. n. sp. as an early-diverging sphenodontian with fully acrodont tooth implantation. The maxillary dentition appears functionally suited for processing hard arthropod exoskeletons and snail shells.

Objective
Few studies have examined burnout in psychosocial oncology clinicians. The aim of this systematic review was to summarize what is known about the prevalence and severity of burnout in psychosocial clinicians who work in oncology settings and the factors that are believed to contribute or protect against it.
MethodArticles on burnout (including compassion fatigue and secondary trauma) in psychosocial oncology clinicians were identified by searching PubMed/MEDLINE, EMBASE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, and the Web of Science Core Collection.
ResultsThirty-eight articles were reviewed at the full-text level, and of those, nine met study inclusion criteria. All were published between 2004 and 2018 and included data from 678 psychosocial clinicians. Quality assessment revealed relatively low risk of bias and high methodological quality. Study composition and sample size varied greatly, and the majority of clinicians were aged between 40 and 59 years. Across studies, 10 different measures were used to assess burnout, secondary traumatic stress, and compassion fatigue, in addition to factors that might impact burnout, including work engagement, meaning, and moral distress. When compared with other medical professionals, psychosocial oncology clinicians endorsed lower levels of burnout.
Significance of resultsThis systematic review suggests that psychosocial clinicians are not at increased risk of burnout compared with other health care professionals working in oncology or in mental health. Although the data are quite limited, several factors appear to be associated with less burnout in psychosocial clinicians, including exposure to patient recovery, discussing traumas, less moral distress, and finding meaning in their work. More research using standardized measures of burnout with larger samples of clinicians is needed to examine both prevalence rates and how the experience of burnout changes over time. By virtue of their training, psychosocial clinicians are well placed to support each other and their nursing and medical colleagues.

Background
Despite knowing for many decades that depressive psychopathology is common in first-episode schizophrenia spectrum disorders (FES), there is limited knowledge regarding the extent and nature of such psychopathology (degree of comorbidity, caseness, severity) and its demographic, clinical, functional and treatment correlates. This study aimed to determine the pooled prevalence of depressive disorder and caseness, and the pooled mean severity of depressive symptoms, as well as the demographic, illness, functional and treatment correlates of depressive psychopathology in FES.
MethodsThis systematic review, meta-analysis and meta-regression was prospectively registered (CRD42018084856) and conducted in accordance with PRISMA and MOOSE guidelines.
ResultsForty studies comprising 4041 participants were included. The pooled prevalence of depressive disorder and caseness was 26.0% (seven samples, N = 855, 95% CI 22.1–30.3) and 43.9% (11 samples, N = 1312, 95% CI 30.3–58.4), respectively. The pooled mean percentage of maximum depressive symptom severity was 25.1 (38 samples, N = 3180, 95% CI 21.49–28.68). Correlates of depressive psychopathology were also found.
ConclusionsAt least one-quarter of individuals with FES will experience, and therefore require treatment for, a full-threshold depressive disorder. Nearly half will experience levels of depressive symptoms that are severe enough to warrant diagnostic investigation and therefore clinical intervention – regardless of whether they actually fulfil diagnostic criteria for a depressive disorder. Depressive psychopathology is prominent in FES, manifesting not only as superimposed comorbidity, but also as an inextricable symptom domain.

We investigated human understanding of different network visualizations in a large-scale online experiment. Three types of network visualizations were examined: node-link and two different sorting variants of matrix representations on a representative social network of either 20 or 50 nodes. Understanding of the network was quantified using task time and accuracy metrics on questions that were derived from an established task taxonomy. The sample size in our experiment was more than an order of magnitude larger (N = 600) than in previous research, leading to high statistical power and thus more precise estimation of detailed effects. Specifically, high statistical power allowed us to consider modern interaction capabilities as part of the evaluated visualizations, and to evaluate overall learning rates as well as ambient (implicit) learning. Findings indicate that participant understanding was best for the node-link visualization, with higher accuracy and faster task times than the two matrix visualizations. Analysis of participant learning indicated a large initial difference in task time between the node-link and matrix visualizations, with matrix performance steadily approaching that of the node-link visualization over the course of the experiment. This research is reproducible as the web-based module and results have been made available at: https://osf.io/qct84/.

Background
Identifying characteristics of individuals at greatest risk for prolonged grief disorder (PGD) can improve its detection and elucidate the etiology of the disorder. The Safe Passage Study, a study of women at high risk for sudden infant death syndrome (SIDS), prospectively examined the psychosocial functioning of women while monitoring their healthy pregnancies. Mothers whose infants died of SIDS were followed in bereavement.
MethodsPre-loss data were collected from 12 000 pregnant mothers and analyzed for their associations with grief symptoms and PGD in 50 mothers whose infants died from SIDS, from 2 to 48 months after their infant's death, focusing on pre-loss risk factors of anxiety, depression, alcohol use, maternal age, the presence of other living children in the home, and previous child loss.
ResultsThe presence of any four risk factors significantly predicted PGD for 24 months post-loss (p < 0.003); 2–3 risk factors predicted PGD for 12 months (p = 0.02). PGD rates increased in the second post-loss year, converging in all groups to approximately 40% by 3 years. Pre-loss depressive symptoms were significantly associated with PGD. Higher alcohol intake and older maternal age were consistently positively associated with PGD. Predicted risk scores showed good discrimination between PGD and no PGD 6–24 months after loss (C-statistic = 0.83).
ConclusionsA combination of personal risk factors predicted PGD in 2 years of bereavement. There is a convergence of risk groups to high rates at 2–3 years, marked by increased PGD rates in mothers at low risk. The risk factors showed different effects on PGD.

Objectives: Medical devices are ubiquitous in modern medical care. However, little is known about the epidemiology of medical devices in the healthcare marketplace, including the rate at which medical devices are subject to recalls or other advisories. We sought to study the epidemiology of medical devices in Canada, focusing on device recalls. In Canada, a recall may signify a variety of events, ranging from relatively minor field safety notifications, to removal of a product from the marketplace.
Methods: We used data from Health Canada to study medical device recalls in Canada from 2005 to 2015. We analyzed the risks of medical device recalls according to the risk class of the device (I lowest; IV highest) and the hazard priority of the recall (Type I highest potential harm; Type III lowest potential harm).
Results: During a 10-year period, there were 7,226 medical device recalls. Most recalls were for intermediate risk class (Class II, 40.1 percent; Class III, 38.7 percent) medical devices. Among recalled devices, 5.0 percent were judged to have a reasonable probability of serious adverse health consequences or death (Type I recall Hazard Priority classification). While the number of medical devices marketed in Canada is not known, over a similar 10-year period, 24,849 new Class II, II, and IV medical device licenses were issued by Health Canada.
Conclusions: Several hundred medical device recalls occur in Canada each year. Further research is needed to characterize the nature of medical device recalls, and to explore how consumers use information about recalls.

Results from the “Potato Ecosystem Project,” a cropping systems study in northern Maine, were used to test the hypothesis that greater reliance on organic nutrient sources and less reliance on synthetic fertilizer sources can benefit weed management efforts. ‘Atlantic’ potato was grown in a 2-yr rotation within a factorial arrangement of three pest management systems, two soil management systems, and both rotation entry points. Weed control in the conventional (CONV) pest management system relied on full rates of herbicides, whereas the biointensive (BIO) system relied exclusively on cultivation. The reduced input (RI) pest management system relied on cultivation in 1991 and 1992 and on 50% of standard herbicide rates plus cultivation from 1993 to 1995. The two soil management systems, unamended (barley/red clover rotation crop; 1× synthetic fertilizer for potato) and amended (pea/oat/hairy vetch green manure rotation crop; manure, compost, and 0.5× synthetic fertilizer for potato) contrasted practices typical for the region to those designed to achieve rapid improvements in soil quality. Midseason weed biomass in potato was dominated by common lambsquarters. In 1991 and 1992, weed biomass in potato was least in the CONV system and did not differ between the RI and BIO systems. In 1993, weeds in both RI and CONV potatoes were effectively suppressed below the level measured in the BIO system. Soil management had no effect on weed biomass from 1991 to 1993 but became an important factor affecting weeds in the BIO system in 1994 and 1995. Weed biomass was 77% lower in 1994 and 72% lower in 1995 in the amended soil management system than in the unamended system. No significant yield loss due to weeds was detected in the 1994 BIO system, but in 1995 yield loss due to weeds was 37% in the unamended system compared to 12% in the amended system. Soil management effects on weeds in the 1994 BIO pest management system carried through to the following season's germinable seed bank. Density of germinable common lambsquarters seed (0 to 10 cm soil depth) in the 1995 BIO system was 4,082 m−2 in the unamended soil management system compared to 1,280 m−2 in the amended soil management system. We suggest that organic amendments and green manure promote a potato crop better able to compete with weeds and that these inputs be considered as potentially important components of integrated weed management systems that have minimal reliance on herbicides.

Internal snow–cover structure depicted by conventional snow profiles is commonly held to be important for avalanche forecasting but it is largely omitted from numerical forecasting schemes owing to quantification difficulties. A subjective test given to practising forecasters illustrated the complex roles of measured profile parameters in describing instability. A clustering technique of pattern recognition, after introducing a snow–profile training set, has demonstrated an objective ability to sort correctly 86% of the layer boundaries associated with slab–avalanche bed surfaces or lubricating layers. Further improvement in stability recognition comes from a newly devised shear test driven by a wedge which quickly locates failure planes within the snow cover. The cluster analysis is then able to sort with similar accuracy between stable and unstable (avalanching) failure planes so located.

Individuals working for the emergency services often bear witness to distressing events. This outcome study examines therapeutic interventions for Fire Service personnel (FSP) experiencing symptoms of trauma, depression, anxiety and low levels of self-compassion. This study aims to investigate the effectiveness of using Compassion-Focused Therapy (CFT) as an adjunct to Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) in reducing symptoms of trauma, anxiety and depression and increasing self-compassion. A convenience sample (n = 17) of participants, referred for therapy following a traumatic incident, were allocated to receive 12 sessions of either TF-CBT or TF-CBT coupled with CFT. The study employed a repeated-measures design. Data were gathered pre- and post-therapy, using three questionnaires: (1) Hospital Anxiety and Depression Scale; (2) Impact of Events Scale-R; (3) Self-Compassion Scale – Short Form. TF-CBT combined with CFT was more effective than TF-CBT alone on measures of self-compassion. Significant reductions in symptoms of depression, anxiety, hyperarousal, intrusion and avoidance and a significant increase in self-compassion occurred in both groups post-therapy. The study provides some preliminary evidence to suggest that FSP may benefit from therapeutic interventions aimed at cultivating self-compassion. Further research is warranted using a larger sample size and adequately powered randomized controlled trial, to detect statistically significant differences and to negate the risk of confound due to low numbers resulting in significant differences between groups at baseline. Using CFT as an adjunct to TF-CBT may help FSP, who bear witness to the distress of others, cultivate compassion for their own suffering.

Summary
The fact that crime and disorder are concentrated at a few places is interesting and deserves an explanation. It is also interesting that places show up in other criminological theories and in other disciplines. And it is useful to understand the methods for studying places. However, a primary reason we are interested in high-crime places is that it might be possible to do something about crime by addressing these places. We are convinced that focusing on places can substantially reduce crime and disorder. Our conviction is not a matter of faith, but is based on over twenty-five years of accumulating evidence.
This chapter summarizes the research evidence examining whether focusing on crime places reduces crime. We first discuss a broad range of place-based prevention strategies examined by Eck and Guerrette (2012). This review provides strong evidence for a place-based approach to crime prevention. We then turn to a specific form of place-based crime prevention – hot spots policing (Sherman and Weisburd 1995). Again, we have a strong body of evidence supporting a place-based approach. Having reviewed hot spots policing, we turn to the importance of place managers and third parties in controlling problem places. We then examine an extension of the third-party approach to argue that a place-based approach to crime may free crime control policy from the police monopoly. Then we describe how a place-based approach to crime could be incorporated in community corrections to improve probation and parole outcomes. Finally, we review the larger body of research on the potential threat of crime displacement, and its opposite, the diffusion of crime control benefits. Consistently, the evidence described in this chapter clearly shows the substantial utility of a place-based approach for reducing crime.
SITUATIONAL CRIME PREVENTION AT PLACES
In Chapter 3 we argued for the importance of social disorganization theories for understanding crime places. This is an area where basic research suggests promise (e.g., see Weisburd et al. 2012; Weisburd et al. 2014), but where there is little evidence of effectiveness of specific practices. Such evidence is beginning to be developed, but we can say little at this juncture. In contrast, the evidence regarding opportunity reduction and crime has grown systematically over the last few decades.

Summary
Take a moment to imagine a crime occurring – perhaps a street robbery or a bag snatch. When you do this, it is difficult not to visualize the crime occurring in a particular setting or place. So, you might imagine a dark street corner with dim street lighting or seating in the outside area of a public bar. It seems intuitively sensible to analyze and understand crime at this unit of analysis – in other words, to investigate how criminals behave and crime concentrates at small microplaces. However, engaging in such microlevel analysis has tended to be a more recent criminological undertaking, and there are still many fruitful avenues to explore in terms of advancing both our knowledge and the sophistication of the methods that we use in this research area.
In this chapter, we raise and endeavor to answer a number of questions concerning the appropriate scale of analysis of criminological enquiry. To do this, we will start by defining what we mean by place and how this differs from other geographic concepts. Next, we highlight what has become the key catalyst for the criminology of place – the tremendous concentration of crime at microgeographic units of analysis. The strong and consistent concentration of crime at addresses, street segments, and other microgeographic units across cities is key to understanding why it is important to study the criminology of place and why it has such strong policy implications. We then turn to some additional statistical benefits of studying crime at microgeographic units that have to do with what is often termed “spatial interaction effects.” Finally, we examine problems that crime and place researchers will need to consider, and recommend some future directions for research exploring crime concentration at places.
PLACE AND SPACE
Geographic concepts are sometimes used in criminological research without a clear understanding of their meaning. Place and space are two such concepts. The subtle difference between them is important to keep in mind, as they can be a guide to establishing a carefully constructed study and influence the interpretation of findings. Furthermore, as will become apparent later in this chapter, a confusion of these concepts can mislead the reader in the interpretation of an argument. For example, it is important to keep in mind that place does not necessarily mean small units of analysis, nor does space necessarily refer to large areas.

Over the last two decades, there has been increased interest in the distribution of crime and other antisocial behavior at lower levels of geography. The focus on micro geography and its contribution to the understanding and prevention of crime has been called the 'criminology of place'. It pushes scholars to examine small geographic areas within cities, often as small as addresses or street segments, for their contribution to crime. Here, the authors describe what is known about crime and place, providing the most up-to-date and comprehensive review available. Place Matters shows that the study of criminology of place should be a central focus of criminology in the twenty-first century. It creates a tremendous opportunity for advancing our understanding of crime, and for addressing it. The book brings together eighteen top scholars in criminology and place to provide comprehensive research expanding across different themes.

Summary
This chapter explores the importance of place in theory and research in both mainstream criminology and other disciplines. As we noted in earlier chapters, traditional criminology has focused primarily on understanding why people commit crime. This focus on criminality has generally inhibited study of microgeographies and their role in producing crime. However, more recently there has been a trend toward integrating microgeographic places into traditional theorizing about criminality. In the first part of the chapter we discuss this trend, focusing on some recent innovations in understanding criminality that have incorporated place-based perspectives. In the second part of the chapter we focus on how other disciplines have influenced thinking in this area, focusing in particular on contributions in psychology, economics, and public health. Finally, we explore how trends in other disciplines might influence future directions of study in the criminology of place.
THE GROWING ROLE OF MICROGEOGRAPHIC PLACES IN TRADITIONAL THEORIZING OF CRIMINALITY
As we noted in Chapter 1, places, at least at a macro level, played a key part in the development of criminology in the nineteenth and early twentieth centuries. But despite the role of place in crime in empirical study in Europe and theoretical development in the Chicago School through social disorganization theory, microgeographic places were mostly ignored. This was not because early criminologists failed to recognize the role of place in crime. Crime occurs in specific environments, and this was apparent to observers of the crime problem. Nonetheless, as we noted in Chapter 1, early criminologists did not see “crime places” – small discrete areas within communities – as a relevant focus of criminological study. This was the case, in part, because crime opportunities provided by places were assumed to be so numerous as to make concentration on specific places of little utility for theory or policy. What is the point of focusing theory or research on the opportunities offered by specific places if such opportunities can be found throughout the urban context?
Moreover, criminologists did not see the utility in focusing in on situational opportunities when criminal motivation was the key to understanding crime rates. Criminologists traditionally assumed that situational factors played a relatively minor role in explaining crime as compared with the “driving force of criminal dispositions” (Clarke and Felson 1993, 4; Trasler 1993).

Summary
In the previous chapter, we showed that crime is concentrated at very small geographic units, substantially smaller than neighborhoods, and that these concentrations, on average, are relatively stable. This is true whether examining high- or low-crime neighborhoods. Although high-crime places do cluster, they seldom form a homogeneous block of high-crime places. Rather, interspersed within concentrations of high-crime places are many low- and modest-crime places.
Why is crime concentrated in a relatively small number of places? Standard criminology has not asked this question, largely because standard criminology focuses on criminality and implicitly assumes that the density of offenders explains crime density. Recognition that place characteristics matter is the starting point for this chapter. We look at two perspectives on crime place characteristics. We use the term “perspective” because each type of explanation is comprised of multiple theories linked by a common orientation. The first perspective arises from opportunity theories of crime. The second perspective arises from social disorganization theories of crime.
We begin by contrasting two ways of thinking about how a place becomes a crime hot spot and suggest that the process by which high-crime places evolve must involve place characteristics. In the next sections, we examine opportunity and social disorganization explanations. In the final section of the chapter, we examine possible ways researchers might link these two perspectives.
PROCESSES THAT CREATE CRIME PLACES
Before we look for explanations of why places become hot spots of crime it is important to consider two processes that might lead to such an outcome. Criminologists have generally proposed two generic models to account for the processes that lead to variation in place susceptibility to crime. One model suggests that places may start with reasonably similar risks of an initial criminal attack, but once attacked the risk of a subsequent attack on the place rises. Over time, places diverge in their crime risk, and consequently in their crime counts. This temporal contagion model is also known as a boost model (see Chapter 2) or a state-dependence model. It puts the emphasis on offenders’ willingness to return to a previously successful crime site (Johnson et al. 2007; Townsley et al. 2000). It suggests that irrespective of initial crime risk the occurrence of a crime will lead to changes in risk of crime at a place.
