A review of Forensic Entomology in the Pacific United States
Authors: Meeds Andrew W. , Parrott Jonathan J. 
Published: August 2021

AbstractThe field of forensic entomology has grown exponentially within the last 50 years. While research in this discipline is conducted globally, the United States in particular has produced a significant amount of work relevant to forensic entomology. The Pacific region of the United States, characterized to include Hawai'i, Idaho, Oregon, Washington and the islands of American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands, has produced a broad array of such studies. Works of interest include surveys of forensically important insects, studies on carrion decomposition and insect succession, studies on the developmental rate of sarcosaprophagous insects, molecular studies to detect differences between geographically distant populations of the same species, studies on the microbial makeup of carrion and carrion‐feeding insects, entomotoxicological research, decomposition communities in aquatic environments, and case reports detailing insects recovered from death investigations as well as myiasis of livestock and humans. This review will outline research that originates from each of the aforementioned regions and review the results, while identifying knowledge gaps, and providing recommended areas of improvement to further increase diversity of forensic entomology research in the Pacific region.This article is categorized under:Forensic Anthropology > Time Since Death EstimationForensic Biology > Forensic Entomology

ABSTRACTGreater sage‐grouse (Centrocercus urophasianus) have experienced considerable range contraction and reduced abundance in response to habitat loss and degradation. Translocation is a conservation action that is often used to reintroduce extirpated populations or augment existing small populations. Translocations have had limited success in restoring viable populations of sage‐grouse; a lack of success is attributed to long‐distance post‐release movements away from release sites, reduced survival, and lack of reproductive success of translocated individuals. Translocating female sage‐grouse with their chicks (brood translocation) is a technique aimed at promoting breeding area fidelity and reproduction and may be beneficial to population restoration efforts. Furthermore, the ability to capture, relocate, and release individuals while minimizing translocation‐induced loss increases the overall probability of restoration success. Accordingly, we developed a protocol to translocate female sage‐grouse and their broods simultaneously, using a delayed‐release system that included a custom release box and acclimation pen. We tested our protocol across 2 separate restoration projects in North Dakota and California during 2017–2019 with a total of 38 translocated females and 196 chicks. We successfully released 174/196 chicks (88.8%) from 32/38 (84.2%) broods. Our protocol builds on existing translocation methods used to translocate sage‐grouse and will likely prove to be a critical technique in restoring sage‐grouse populations. © 2021 The Wildlife Society.
The averaging bias ‐ A standard miscalculation, which extensively underestimates real CO2 emissions
Authors: Koch Thomas , Böhlke Thomas 
Published: August 2021

AbstractThe substitution of energy based on fossil fuels in different sectors like household or traffic by electric energy saves CO2 of this specific sector due to decreased fossil fuel consumption. An important quantity is the additional CO2 emission due to an increased electric power demand for the average electricity power demand . Commonly, the formula is used (called simplified formula), where represents mean average CO2 footprint. It is shown in the present manuscript, that the simplified formula may underestimate the CO2 footprint significantly if the average CO2 footprint depends on the average electricity power demand, which is the case for most of mixed partly renewable and partly non‐renewable electric energy systems. Therefore, the real CO2 emissions would outmatch those according to simplified easily by factor 2 in reality depending on the status of the electricity system. In order to establish a more precise calculation of the CO2 footprint, the general formula which is exact and contains the simplified formula as a special case, is derived in this article. The simplified formula requires an additional term that takes into account the change of the mean average CO2 footprint depending on the electricity power demand.
The Organization of Soil Fragments
Authors: Verrecchia Eric P. , Trombino Luca 
Published: August 2021

AbstractKubiëna (1938) was the first to introduce the concept of fabric in soil micromorphology, so this term has been used in soil micromorphology for a long time. The term “fabric” was initially applied to rocks by geologists and petrologists. This type of fabric is defined as the “factor of the texture of a crystalline rock which depends on the relative sizes, the shapes, and the arrangement of the component crystals” (Matthews and Boyer 1976). This definition has been adapted for soil micromorphology and its latest definition has been given by Bullock et al. (1985) as: “soil fabric deals with the total organization of a soil, expressed by the spatial arrangement of the soil constituents (solid, liquid, and gaseous), their shape, size, and frequency, considered from a configurational, functional and genetic view-point”. In conclusion, the soil micromorphologist should consider the fabric as an arrangement and∕or organization of soil constituents.
Reciprocal Student–Teacher Feedback: Effects on Perceived Quality of Cooperation and Teacher Health
Authors: Schmidt Jan-Erik , Gawrilow Caterina 
Published: August 2021

AbstractHigh lesson quality in schools is, in addition to other factors, the result of good cooperation between teachers and students. The long history of research on offer-use models of lesson quality and student–teacher relationships documents this interaction. Feedback focused on expressing the quality of cooperation can lead to higher quality of cooperation. The fact that feedback is reciprocal, from teacher to student and vice versa, helps to avoid effects of perceived injustice and rejections of feedback which otherwise are severe obstacles to the efficient use of feedback. High-frequency applications of feedback allow for the timely detection of (positive and negative) critical fluctuations of cooperation between individuals and groups and for the monitoring of processes of adaptation, as shown in other areas of applied psychology. This chapter describes the theoretical parameters of such a feedback method for students and teachers, and outlines results of an empirical study on the effects of the reciprocal method on (1) perceived quality of cooperation and (2) teacher health. Results show that, subsequent to a three-month period of reciprocal feedback, the quality of cooperation as perceived by both students and their teachers increases significantly and teacher health scores improve significantly. Reciprocal feedback techniques should be considered in teacher education and teacher training as a way to help teachers to initiate processes of improvement of lesson quality.

Published: August 2021

Abstract
Purpose
Previous research has identified social support to be associated with risk of posttraumatic stress disorder (PTSD) symptoms among military personnel. While the lack of social support influences PTSD symptomatology, it is unknown how changes in perceived social support affect the PTSD symptom level in the aftermath of deployment. Furthermore, the influence of specific sources of social support from pre- to post-deployment on level of PTSD symptoms is unknown. We aim to examine how changes in perceived social support (overall and from specific sources) from pre- to 2.5 year post-deployment are associated with the level of post-deployment PTSD symptoms.

Methods
Danish army military personnel deployed to Afghanistan in 2009 and 2013 completed questionnaires at pre-deployment and at 2.5 year post-deployment measuring perceived social support and PTSD symptomatology and sample characteristics of the two cohorts. Data were analyzed using univariate and multivariate nominal logistic regression.

Results
Negative changes in perceived social support from pre- to post-deployment were associated with both moderate (OR 1.99, CI 1.51–2.57) and high levels (OR 2.71, CI 1.94–3.78) of PTSD symptoms 2.5 year post-deployment (adjusted analysis). Broadly, the same direction was found for specific sources of social support and level of PTSD symptoms. In the adjusted analyses, pre-deployment perceived social support and military rank moderated the associations.

Conclusions
Deterioration in perceived social support (overall and specific sources) from pre- to 2.5 year post-deployment increases the risk of an elevated level of PTSD symptoms 2.5 year post-deployment.

Published: August 2021

Abstract
Background
A large proportion of sickness absence (SA) in young adults is due to common mental disorders (CMDs). Still studies on CMD-related SA in young workers are lacking, especially studies for those employed in the private sector. The current study investigated the associations between sector of employment, occupational class and SA due to CMDs. In addition, associations between type of employment branch and SA due CMDs within each sector were examined.

Methods
This population-based longitudinal cohort study included 663,583 employees, 19–29 years, residing in Sweden in 2009. Employment sector (i.e., private/public) and occupational class (non-manual/manual workers) were measured in 2009. Risk estimates of SA due to CMDs, between 2010 and 2016, were calculated as Hazard Ratios (HR) with 95% confidence intervals (CI), using Cox regression analysis.

Results
Sector of employment was associated with SA due to CMDs, such that public sector workers had an elevated risk when compared with private sector employees (adjusted HR: 1.31 (95% CI 1.29–1.33). Moreover, manual workers had a slightly elevated risk for SA due to CMDs compared to non-manual workers. Within the private sector, in both manual and non-manual workers, those employed in education and health and social services evidenced the highest rates and risks of SA due to CMDs.

Conclusion
Sector of employment and occupational class play a role in SA due to CMDs in young employees. These findings should be considered when identifying high-risk groups for SA in the young working population.
The dynamic relationship between hearing loss, quality of life, socioeconomic position and depression and the impact of hearing aids: answers from the English Longitudinal Study of Ageing (ELSA)

Published: August 2021

Abstract
Purpose
The adverse impact of hearing loss (HL) extends beyond auditory impairment and may affect the individuals' psychosocial wellbeing. We aimed to examine whether there exists a causal psychosocial pathway between HL and depression in later life, via socioeconomic factors and quality of life, and whether hearing aids usage alleviates depressive symptoms over time.

Methods
We examined the longitudinal relationship between HL and depressive symptoms (CES-D) applying dynamic cross-lagged mediation path models. We used the full dataset of participants aged 50–89 years (74,908 person-years), from all eight Waves of the English Longitudinal Study of Ageing (ELSA). Their quality of life (CASP-19) and their wealth were examined as the mediator and moderator of this relationship, respectively. Subgroup analyses investigated differences among those with hearing aids within different models of subjectively and objectively identified HL. All models were adjusted for age, sex, retirement status and social engagement.

Results
Socioeconomic position (SEP) influenced the strength of the relationship between HL and depression, which was stronger in the lowest versus the highest wealth quintiles. The use of hearing aids was beneficial for alleviating depressive symptoms. Those in the lowest wealth quintiles experienced a lower risk for depression after the use of hearing aids compared to those in the highest wealth quintiles.

Conclusion
HL poses a substantial risk for depressive symptoms in older adults, especially those who experience socioeconomic inequalities. The early detection of HL and provision of hearing aids may not only promote better-hearing health but could also enhance the psychosocial wellbeing of older adults, particularly those in a lower SEP.

Abstract
Purpose
Perigenual anterior cingulate cortex (pACC) is a neural convergence site for social stress-related risk factors for mental health, including ethnic minority status. Current social status, a strong predictor of mental and somatic health, has been related to gray matter volume in this region, but the effects of social mobility over the lifespan are unknown and may differ in minorities. Recent studies suggest a diminished health return of upward social mobility for ethnic minority individuals, potentially due to sustained stress-associated experiences and subsequent activation of the neural stress response system.

Methods
To address this issue, we studied an ethnic minority sample with strong upward social mobility. In a cross-sectional design, we examined 64 young adult native German and 76 ethnic minority individuals with comparable sociodemographic attributes using whole-brain structural magnetic resonance imaging.

Results
Results showed a significant group-dependent interaction between perceived upward social mobility and pACC gray matter volume, with a significant negative association in the ethnic minority individuals. Post-hoc analysis showed a significant mediation of the relationship between perceived upward social mobility and pACC volume by perceived chronic stress, a variable that was significantly correlated with perceived discrimination in our ethnic minority group.

Conclusion
Our findings extend prior work by pointing to a biological signature of the “allostatic costs” of socioeconomic attainment in socially disadvantaged upwardly mobile individuals in a key neural node implicated in the regulation of stress and negative affect.
Topology optimization for fail-safe designs using moving morphable components as a representation of damage
Authors: Hederberg Hampus , Thore Carl-Johan 
Published: August 2021

AbstractDesigns obtained with topology optimization (TO) are usually not safe against damage. In this paper, density-based TO is combined with a moving morphable component (MMC) representation of structural damage in an optimization problem for fail-safe designs. Damage is inflicted on the structure by an MMC which removes material, and the goal of the design problem is to minimize the compliance for the worst possible damage. The worst damage is sought by optimizing the position of the MMC to maximize the compliance for a given design. This non-convex problem is treated using a gradient-based solver by initializing the MMC at multiple locations and taking the maximum of the compliances obtained. The use of MMCs to model damage gives a finite element-mesh-independent method, and by allowing the components to move rather than remain at fixed locations, more robust structures are obtained. Numerical examples show that the proposed method can produce fail-safe designs with reasonable computational cost.
Sarcopenia in Chronic Kidney Disease: A Scoping Review of Prevalence, Risk Factors, Association with Outcomes, and Treatment

Published: August 2021

AbstractSarcopenia, a condition characterized by loss of skeletal muscle mass and function, has important clinical ramifications. We aimed to map the existing literature about prevalence, risk factors, associated adverse outcomes, and treatment of sarcopenia in individuals with chronic kidney disease (CKD). A scoping review of the literature was conducted to identify relevant articles published from databases’ inception to September 2019. Individuals with CKD, regardless of their disease stage and their comorbidities, were included. Only studies with sarcopenia diagnosed using both muscle mass and function, based on published consensus definitions, were included. For studies on treatment, only randomized controlled trials with at least one sarcopenia parameter as an outcome were included. Our search yielded 1318 articles, of which 60 from were eligible for this review. The prevalence of sarcopenia ranged from 4 to 42% according to the definition used, population studied, and the disease stage. Several risk factors for sarcopenia were identified including age, male gender, low BMI, malnutrition, and high inflammatory status. Sarcopenia was found to be associated with several adverse outcomes, including disabilities, hospitalizations, and mortality. In CKD subjects, several therapeutic interventions have been assessed in randomized controlled trial with a muscle mass, strength, or function endpoint, however, studies focusing on sarcopenic CKD individuals are lacking. The key interventions in the prevention and treatment of sarcopenia in CKD seem to be aerobic and resistance exercises along with nutritional interventions. Whether these interventions are effective to treat sarcopenia and prevent clinical consequences in this population remains to be fully determined.
CT-guided transforaminal epidural steroid injection for discogenic lumbar radiculopathy: influence of contrast dispersion and radiologist’s experience on clinical outcome

Published: August 2021

Abstract
Objective
To investigate the impact of contrast dispersion pattern/location during lumbar CT-guided transforaminal epidural steroid injection (TFESI) and experience of the performing radiologist on therapeutic outcome.

Materials and methods
In this single-center retrospective cohort study, two observers analyzed contrast dispersion during CT-guided TFESI of 204 patients (age 61.1 ± 14 years) with discogenic unilateral single-level L4 or L5 radiculopathy. The contrast dispersion pattern was classified as “focal,” “linear,” or “tram-track”; the location was divided into “extraforaminal,” “foraminal,” or “recessal.” Pain was assessed before and 4 weeks after treatment using a numerical rating scale (0, no pain; 10, intolerable pain). Additionally, the patient global impression of change (PGIC) was assessed. The TFESI was performed by musculoskeletal radiologists (experience range: first year of musculoskeletal fellowship training to 19 years). Contrast pattern/location and radiologist’s experience were compared between “good responder” (≥ 50% pain reduction) and “poor responder” (< 50%). A p-value < 0.05 was considered to be statistically significant.

Results
Overall, CT-guided TFESI resulted in a substantial pain reduction in 46.6% of patients with discogenic radiculopathy. The contrast dispersion pattern and location had no effect on pain relief (p = 0.75 and p = 0.09) and PGIC (p = 0.70 and p = 0.21) 4 weeks after TFESI. Additionally, the experience of the radiologist had no influence on pain reduction (p = 0.92) or PGIC (p = 0.75). Regarding pre-interventional imaging findings, both the location and grading of nerve compression had no effect on pain relief (p = 0.91 and p = 0.85) and PGIC (p = 0.18 and p = 0.31).

Conclusion
Our results indicate that neither contrast agent dispersion/location nor the experience of the radiologist allows predicting the therapeutic outcome 4 weeks after the procedure.

AbstractBackgroundPresentation at academic conferences is an important marker of research productivity. However, not all accepted abstracts progress to full publication, and there is anecdotal evidence suggesting an imbalance in sex and ethnicity amongst presenters. There is a lack of data evaluating the outcome of prize presentation sessions at academic surgical conferences in the UK. This study aimed to analyse the outcomes and demographics from presentations at prize sessions at two prestigious UK surgical conferences.MethodsThis retrospective observational study compared data on all Moynihan (Association of Surgeons of Great Britain and Ireland) and Patey (Surgical Research Society) prize presentations from 2000 to 2020. The primary outcome was rate of publication. Secondary outcomes included demographic differences in sex and ethnicity, publication according to prize outcome, academic affiliation, time to publication, and journal impact factor.ResultsSome 442 accepted abstracts were identified over the 21‐year period, with 71.0% from the Moynihan sessions and 79.3% from the Patey sessions leading to full publications, with a median time to publication of 448 days (IQR 179–859) in journals with relatively high impact factors (median 5.00; IQR 3.15–6.36). Of the 442 prize presenters, 85 (19.2%) were female. The majority of the presenters were White males (211, 47.7%), followed by Asian males (112, 25.3%). However, there was a continuously increasing overall trend of female presenters from 2000 to 2020 (P = 0.019).ConclusionPublication rates from the two prize sessions were high, with presenters publishing in journals with high impact factors. There, however, was a disparity in sex and ethnicity amongst presenters.
