Soil microbial succession following surface mining is governed primarily by deterministic factors

Published: June 2020

ABSTRACT
Understanding the successional dynamics governing soil microbial community assembly following disturbance can aid in developing remediation strategies for disturbed land. However, the influences shaping microbial communities during succession following soil disturbance remain only partially understood. One example of a severe disturbance to soil is surface mining for natural resources, which displaces communities and changes the physical and chemical soil environment. These changes may alter community composition through selective pressure on microbial taxa (i.e. deterministic processes). Dispersal and ecological drift may also shape communities following disturbance (i.e. stochastic processes). Here, the relative influence of stochastic and deterministic processes on microbial community succession was investigated using a chronosequence of reclaimed surface mines ranging from 2–32 years post-reclamation. Sequencing of bacterial and fungal ribosomal gene amplicons coupled with a linear modeling approach revealed that following mine reclamation, while bacterial communities are modestly influenced by stochastic factors, the influence of deterministic factors was ∼7 × greater. Fungal communities were influenced only by deterministic factors. Soil organic matter, texture, and pH emerged as the most influential environmental factors on both bacterial and fungal communities. Our results suggest that management of deterministic soil characteristics over a sufficient time period could increase the microbial diversity and productivity of mine soils.
The Press-safety Paradox of Democracies: Regime-type Duration and Journalist Killings
Authors: Solis Jonathan A 
Published: June 2020

Abstract
Previous research finds that journalist killings are more likely to occur in democracies rather than non-democracies. While these results provide an important first step in exploring regime type’s effect on journalist’s safety, they assume no variation in how long countries have remained a regime type. In this paper, I argue that as a country’s regime type endures, the likelihood of seeing journalists killed for their work will decrease. My theory also examines the process in different regime types and argues that this effect should hold for autocracies and anocracies, but not democracies|though democratic consolidation should decrease journalist killings there. Using an original sample of journalists killed for their professional work in countries worldwide from 1992 to 2014, I evaluate my theory using regression and survival analyses and find evidence that as regime types endure, journalist killings decrease, on average. As expected, the result holds for autocracies and anocracies but not democracies. However, the data show democratic consolidation does decrease journalist killings. The results provide a broader understanding of the working dynamics between regime type and journalists’ safety in a country’s media system.
The Changing Adoption of Culture Change Practices in U.S. Nursing Homes

Published: June 2020

Abstract

Background and Objectives
The study aimed to: (i) describe whether culture change (CC) practice implementation related to physical environment, resident-centered care, and staff empowerment increased within the same nursing homes (NHs) over time; and (ii) identify factors associated with observed increases.

Research Design and Methods
This was a nationally representative panel study of 1,584 U.S. NHs surveyed in 2009/2010 and 2016/2017. Survey data were merged with administrative, NH, and market-level data. Physical environment, staff empowerment, and resident-centered care domain scores were calculated at both time points. Multivariate logistic regression models examined factors associated with domain score increases.

Results
Overall, 22% of NHs increased their physical environment scores over time, 32% their staff empowerment scores, and 44% their resident-centered care scores. However, 32%–68% of NHs with below median baseline scores improved their domain scores over time compared with only 11%–21% of NHs with baseline scores at or above the median. Overall, NHs in states with Medicaid pay-for-performance (with CC components), in community care retirement communities, with special care units and higher occupancy had significantly higher odds of increases in physical environment scores. Only baseline domain scores were associated with increases in staff empowerment and resident-centered care scores.

Discussion and Implications
This is the first nationally representative panel study to assess NH CC adoption. Many NHs increased their CC practices, though numerous others did not. While financial incentives and indicators of financial resources were associated with increase in physical environment scores, factors associated with staff empowerment and resident-centered care improvements remain unclear. Studies are needed to assess whether the observed increases in CC adoption are associated with greater quality of life and care gains for residents and whether there is a threshold effect beyond which the efficacy of additional practice implementation may be less impactful.
Patterns of (Dis)similarity in the Design of Regional Organizations: The Regional Organizations Similarity Index (ROSI)
Authors: Jetschke Anja , Münch Sören , Cardozo-Silva Adriana Rocío , Theiner Patrick 
Published: June 2020

Abstract
How similar are the institutional designs of regional organizations (ROs)? Is there a trend toward particular designs such as the European Union's, or is there greater institutional variety as more regions have created an increasing number of ROs? Which designs have spread through the system, and which remain idiosyncratic? To answer these questions, the Comparative Regional Organizations Project has assembled the most detailed dataset on ROs to date, with more than 80 organizations and their 276 founding and amending treaties being coded on more than 300 institutional design features. From these data, the project has generated the Regional Organizations Similarity Index (ROSI), a dyadic measure of the similarity between any two ROs at various points during their existence. We outline the rationale for ROSI and detail its construction, and show that it captures previously unstudied patterns of variation in the RO universe across time and space. In addition to generalizations about the case universe, ROSI allows us to estimate which institutional designs constitute deviations and which tend to follow established models. We demonstrate the validity of ROSI with the help of brief case studies exploring which institutional design features led to the identified scores.

Abstract
In a randomized design study, lambs were individually fed with ad libitum access to 70.9% concentrate diets for 56 d in individual pens. The positive control diet (CNTL) contained cottonseed meal (CSM), sorghum grain, and cottonseed hulls, but no dried distillers’ grains with solubles (DDGS). Four treatment diets were similar to CNTL but did not contain CSM. Corn DDGS replaced 0% (0DDGS), 33% (33DDGS), 66% (66DDGS), or 100% (100DDGS) of the sorghum grain in the treatment diets. At 48-h postmortem, the longissimus muscle (LM) was removed from the carcass, cut into chops, frozen, thawed, cooked, and evaluated by a trained sensory panel. Lambs fed CNTL were compared with 0DDGS using contrasts and linear and quadratic effects were evaluated among the four DDGS diets. Lambs fed CNTL had greater (P ≤ 0.03) hot carcass weight (HCW) and LM area than lambs fed 0DDGS. As DDGS incrementally replaced sorghum grain, marbling linearly decreased (P = 0.03), LM area tended to linearly increase (P = 0.06), and skeletal maturity tended to linearly decrease (P = 0.06). As DDGS incrementally replaced sorghum grain, flavor attributes quadratically increased to 33DDGS then decreased (brown, roasted, umami; P ≤ 0.03), quadratically decreased to 33DDGS then increased (metallic; P = 0.004), or linearly decreased (lamb flavor identity; P = 0.03). Volatile aroma compounds 2-(hexyloxy)-ethanol decreased and 2,3-octanedione and methyl pyrazine increased quadratically with an increase in DDGS (P &lt; 0.05). Additionally, 2-heptenal, heptanal, and 2-pentyl furan increased linearly, while 2-butanone decreased linearly as DDGS increased in the diet (P &lt; 0.05). Results indicate that carcass and sensory characteristics and volatile aroma compounds are not negatively affected, in fact brown, roasted, and umami flavors are enhanced, when 33% DDGS replaces CSM and sorghum grain in Dorper lamb feedlot diets.

Published: June 2020

Abstract
This study compares the ability of liberal vs restrictive intubation criteria to detect prolonged intubation and inhalation injury in burn patients with suspected inhalation injury. Emerging evidence suggests that using liberal criteria may lead to unnecessary intubation in some patients. A single-center retrospective cohort study was conducted in adult patients with suspected inhalation injury admitted to intensive care at Queen Elizabeth Hospital, Birmingham between April 2016 and July 2019. Liberal intubation criteria, as reflected in local guidelines, were compared to restrictive intubation criteria, as outlined in the American Burn Association guidelines. The number of patients displaying positive characteristics from either guideline was compared to the number of patients who had prolonged intubation (more than 48 hours) and inhalation injury. In detecting a need for prolonged intubation (n = 85), the liberal criteria had greater sensitivity (liberal = 0.98 [0.94–1.00] vs restrictive = 0.84 [0.75–0.93]; P = .013). However, the restrictive criteria had greater specificity (restrictive = 0.96 [0.89–1.00] vs liberal = 0.48 [0.29–0.67]; P &lt; .001). In detecting inhalation injury (n = 72), the restrictive criteria were equally sensitive (restrictive = 0.94 [0.87–1.00] vs liberal = 0.98 [0.84–1.00]; P = .48) and had greater specificity (restrictive = 0.86 [0.72–1.00] vs liberal = 0.04 [0.00–0.13]; P &lt; .001). In patients who met liberal but not restrictive criteria, 65% were extubated within 48 hours and 90% did not have inhalation injury. Liberal intubation criteria were more sensitive at detecting a need for prolonged intubation, while restrictive criteria were more specific. Most patients intubated based on liberal criteria alone were extubated within 48 hours. Restrictive criteria were highly sensitive and specific at detecting inhalation injury.

Published: June 2020

Abstract
Wound excision and temporary coverage with a biologic dressing can improve survival for patients with large burns. Healthcare systems in low- and middle-income countries (LMICs) rarely have access to allografts, which may contribute to the limited survival of patients with large burns in these settings. Therefore, we aimed to describe the lessons learned from the implementation and maintenance of tissue banks in LMICs to guide system planning and organization. PubMed, MEDLINE, CINAHL, and World Health Organization Catalog were systematically searched with database-specific language to represent a priori terms (eg, skin, allograft, and tissue bank) and all LMICs as defined by the World Bank. Data regarding tissue banking programs were extracted and described in a narrative synthesis. The search returned 3346 records, and 33 reports from 17 countries were analyzed. Commonly reported barriers to ideal or planned implementation included high capital costs and operational costs per graft, insufficient training opportunities, opt-in donation schemes, and sociocultural stigma around donation and transplantation. Many lessons were learned from the implementation and management of tissue banks around the world. The availability of skin allografts can be improved through strategic investments in governance and regulatory structures, international cooperation initiatives, training programs, standardized protocols, and inclusive public awareness campaigns. Furthermore, capacity-building efforts that involve key stakeholders may increase rates of pledges, donations, and transplantations. Some issues were ubiquitously reported and could be addressed by current and future tissue banking programs to ensure allograft availability for patients living in countries of all income levels.
Essential Oil Components in Superabsorbent Polymer Gel Modify Reproduction ofBlattella germanica(Blattodea: Ectobiidae)
Authors: Oladipupo S O , Hu X P , Appel A G 
Published: June 2020

AbstractThe use of essential oil components (EOCs) against the German cockroach, Blattella germanica (L.), has increasingly received attention from researchers. However, the determination of lethal doses/concentrations alone does not provide enough information on the range of biological effects of these EOCs. To improve our understanding of the potential effects of EOCs, we examined biological parameters of B. germanica exposed to sublethal EOCs formulated in gels. This study employed superabsorbent polymer (SAP) gel to prolong bioavailability of limonene, carvacrol, and β-thujaplicin, and evaluated how these EOCs shape biological parameters of B. germanica. Overall, median survival days ranged from 57 to 69.5 d for males and 73 to 99 d for females. The survival day ranking for the EOCs was limonene &gt; β-thujaplicin &gt; carvacrol. Carvacrol and β-thujaplicin gels reduced male longevity by at least 34 and 39%, respectively, while limonene had no effect. The longevity of females was reduced by limonene, but not by carvacrol and β-thujaplicin gels. EOCs significantly suppressed overall adult females’ reproductive period, oothecal hatchability, reduced fecundity, and interoothecal period, but not the number of oothecae formed and egg incubation period. The preoviposition period (mean: 2–25 d) ranking was limonene &lt; carvacrol &lt; β-thujaplicin. Based on these results, limonene, carvacrol, and β-thujaplicin in SAP gels show promising potential to reduce adult male survival/longevity, suppress egg hatchability and female fecundity, and delay the interoothecal period. These findings may represent the basis for the practical use of EOCs as a tactic in integrated pest management systems for B. germanica.
Impact of Full-Field Digital Mammography Versus Film-Screen Mammography in Population Screening: A Meta-Analysis
Authors: Farber Rachel , Houssami Nehmat , Wortley Sally , Jacklyn Gemma , Marinovich Michael L , McGeechan Kevin , Barratt Alexandra , Bell Katy 
Published: June 2020

Abstract

Background
Breast screening programs replaced film mammography with digital mammography, and the effects of this practice shift in population screening on health outcomes can be measured through examination of cancer detection and interval cancer rates.

Methods
A systematic review and random effects meta-analysis were undertaken. Seven databases were searched for publications that compared film with digital mammography within the same population of asymptomatic women and reported cancer detection and/or interval cancer rates.

Results
The analysis included 24 studies with 16 583 743 screening examinations (10 968 843 film and 5 614 900 digital). The pooled difference in the cancer detection rate showed an increase of 0.51 per 1000 screens (95% confidence interval [CI] = 0.19 to 0.83), greater relative increase for ductal carcinoma in situ (25.2%, 95% CI = 17.4% to 33.5%) than invasive (4%, 95% CI = −3% to 13%), and a recall rate increase of 6.95 (95% CI = 3.47 to 10.42) per 1000 screens after the transition from film to digital mammography. Seven studies (80.8% of screens) reported interval cancers: the pooled difference showed no change in the interval cancer rate with −0.02 per 1000 screens (95% CI = −0.06 to 0.03). Restricting analysis to studies at low risk of bias resulted in findings consistent with the overall pooled results for all outcomes.

Conclusions
The increase in cancer detection following the practice shift to digital mammography did not translate into a reduction in the interval cancer rate. Recall rates were increased. These results suggest the transition from film to digital mammography did not result in health benefits for screened women. This analysis reinforces the need to carefully evaluate effects of future changes in technology, such as tomosynthesis, to ensure new technology leads to improved health outcomes and beyond technical gains.
‘Physically sheltered but existentially homeless’: Losing home in the aftermath of conflict and displacement
Authors: Perez Murcia Luis Eduardo 
Published: June 2020

AbstractThis article explores the interplay between conflict-induced displacement and home. Inspired by Arendt’s discussion on home for those European refugees who were forced to move and deported to Nazi concentration camps during the Second World War, the article argues that displacement results in the loss of a place called home. Drawing on the narratives of those who in the aftermath of conflict have fled within national borders in Colombia, the article shows that displacement consistently results in the loss of home and it is experienced as the loss of people’s place in the world. Their loss of home was not only experienced as the loss of a physical shelter and its financial value but primarily as the loss of a place in which their lives were fulfilled with existential meaning. Despite the fact that the displaced found a new place for dwelling, most of them stressed the feeling of being out of place within their own country. The empirical findings challenge internal displacement research which rather than looking at how displacement disrupts one’s sense of home, has tended to focus on the loss of material assets and the subsequent risk of being trapped by poverty as the most salient impacts of displacement. The article ends by suggesting that the use of a notion of home which is material and symbolic, may provide internal displacement research with new venues for understanding both the very meaning of being displaced and how displacement is experienced.

ABSTRACT
We present the results of optical photometric observations of three extreme TeV blazars, 1ES 0229+200, 1ES 0414+009, and 1ES 2344+514, taken with two telescopes (1.3 m Devasthal Fast Optical Telescope, and 1.04 m Sampuranand Telescope) in India and two (1.4 m Milanković telescope and 60 cm Nedeljković telescope) in Serbia during 2013–2019. We investigated their flux and spectral variability on diverse time-scales. We examined a total of 36 intraday R-band light curves of these blazars for flux variations using the power-enhanced F-test and the nested ANOVA test. No significant intraday variation was detected on 35 nights, and during the one positive detection the amplitude of variability was only 2.26 per cent. On yearly time-scales, all three blazars showed clear flux variations in all optical wavebands. The weighted mean optical spectral index (αBR), calculated using B − R colour indices, for 1ES 0229+200 was 2.09 ± 0.01. We also estimated the weighted mean optical spectral indices of 0.67 ± 0.01 and 1.37 ± 0.01 for 1ES 0414+009, and 1ES 2344+514, respectively, by fitting a single power law (Fν ∝ ν−α) in their optical (VRI) spectral energy distributions. A bluer-when-brighter trend was only detected in the blazar 1ES 0414+009. We briefly discuss different possible physical mechanisms responsible for the observed flux and spectral changes in these blazars on diverse time-scales.
The well correlated diffuse interstellar bands at λλ 6196, 6614 Å and their possible companions
Authors: Bondar A 
Published: June 2020

ABSTRACT
Considered here is the interrelation between five diffuse interstellar bands (DIBs), λλ 5545, 6113, 6196, 6445 and 6614 Å. Two DIBs (λλ 6196 and 6614 Å) are already known as being well correlated with each other; their relation with three other weaker bands is investigated for the first time. To accomplish this task, high-resolution spectra (λ/δλ ≈100 000) with high signal-to-noise ratios (S/N) of 54 hot O–B stars with reddening 0.12–1.45 mag were used. Analysis of measured equivalent widths has allowed us to establish linear dependences and evaluate linear correlation coefficients as high as 0.968–0.988 between the intensities of these five DIBs. Such a degree of correlation may indicate their common origin. Several spacings in wavenumbers found between these DIBs correspond to the energies of vibrational transitions in some polycyclic aromatic hydrocarbons resulting in IR emissions at λλ 16.4, 11.3, 7.7, 6.2 and 3.3 μm.
Modified Hermite integrators of arbitrary order
Authors: Dittmann Alexander J 
Published: June 2020

ABSTRACT
We present a family of modified Hermite integrators of arbitrary order possessing superior behaviour for the integration of Keplerian and near-Keplerian orbits. After recounting the derivation of Hermite N-body integrators of arbitrary order, we derive a corrector expression that minimizes integrated errors in the argument of periapsis for any such integrator. In addition to providing an alternate derivation of the modified corrector for the fourth-order Hermite integrator, we focus on improved correctors for the sixth- and eighth-order integrators previously featured in the literature. We present a set of numerical examples and find that the higher order schemes improve performance, even when considering their slightly higher cost in floating point operations. The algorithms presented herein hold promise for systems dominated by central potentials, such as planetary systems and the centres of galaxies. Existing Hermite integrators of any order can be modified to use the expressions presented here with minimal effort. Accordingly, the schemes presented herein can be easily implemented on massively parallel architectures.
