Authors: Zhao Fangjie , Hu Chaoqun , Xu Zhenqing , Deng Qiangyu , Wu Yaomin , Zhang Lulu
Published: October 2019

Objectives:

To study injury patterns and medical rescue operations related to tornadoes that occur in rural areas, this study investigated the data pertaining to the 2017 Chifeng tornado (China).

Methods:

Medical records of 52 tornado-related patients were investigated. Data were collected from 3 local hospitals that received all the tornado victims.

Results:

A total of 148 injuries were diagnosed. Tornado-related injuries were mainly caused by collapsed houses (51.9%) and direct physical trauma caused by the tornado (38.5%). Most injuries occurred outdoors (63.5%). The head (20.3%) and thorax (14.8%) were most 2 frequent anatomical injury sites. Soft-tissue injuries (43.9%) and contusions and lacerations (37.3%) were the 2 most common injury types. On evaluating the Abbreviated Injury Scale scores, a score of 1 was the most common (66.2%), and a score of 6 was not recorded.

Conclusions:

A trailing phenomenon in the distribution of time to admission among the victims of a particular tornado in China was observed. The delivery is timely compared with nondisaster situation. There was a statistically significant difference of injury causes between outdoor and indoor patients. Helmets should be used by potential tornado victims. Basement units capable of functioning as shelters should be built in villages.
Appalachia andLaudato Si’: Developing the Connection between the Poor and the Environment
Authors: King Jason
Published: October 2019

In Laudato Si’, Pope Francis links environmental degradation and the poor, writing that “the poor and the earth are crying out.” Appalachia complicates the pope's claim, however, because it is an area that suffers from environmental degradation but also supports the Trump administration's dismantling of environmental regulations. Thus, Pope Francis’ understanding of the poor in Laudato Si’ needs development in three ways. First, he needs to explore how environmental degradation causes spiritual harm in addition to physical harm. Second, the pope needs to note that spiritual harm often causes the poor to cry out in ways that are sexist, racist, homophobic, and hostile toward the environment. Finally, the pope should note that the voices to be heeded in responding to environmental degradation are those voices marginalized within poor communities because they are most likely to address the spiritual harm and avoid scapegoating others.
Catholic Fasting Literature in a Context of Body Hatred: A Feminist Critique
Authors: Coblentz Jessica
Published: October 2019

Some concerned Catholic theologians and popular writers have addressed the ubiquity of body hatred in the United States in their prescriptive considerations of liturgical fasting. This essay brings a feminist theological lens to their writings to argue that this Catholic fasting literature presents dualistic and decontextualized accounts of embodiment and of sacramental practice that reify the discursive structures of body hatred in the US context. In response, the author advocates for a shift in Catholic theological discourse about fasting as one attempt to resist body hatred and support more liberative possibilities for embodiment in this context.*
Health outcomes attributable to carbapenemase-producing Enterobacteriaceae infections: A systematic review and meta-analysis
Authors: Budhram Dalton R. , Mac Stephen , Bielecki Joanna M. , Patel Samir N. , Sander Beate
Published: October 2019

Background:

Carbapenemase-producing Enterobacteriaceae (CPE) pose a significant global health threat.

Objective:

To conduct a systematic review of health outcomes and long-term sequelae attributable to CPE infection.

Methods:

We followed PRISMA reporting guidelines and published our review protocol on PROSPERO (CRD42018097357). We searched Medline, Embase, CINAHL and the Cochrane Library. We included primary studies with a carbapenem-susceptible control group in high-income countries, published in English. Quality appraisal was completed using Joanna Briggs Institute checklists. We qualitatively summarized frequently reported outcomes and conducted a meta-analysis.

Results:

Our systematic review identified 8,671 studies; 17 met the eligibility criteria for inclusion. All studies reported health outcomes; none reported health-related quality-of-life. Most studies were from Europe (65%), were conducted in teaching or university-affiliated hospitals (76%), and used case-control designs (53%). Mortality was the most commonly reported consequence of CPE-infections; in-hospital mortality was most often reported (62%). Our meta-analysis (n = 5 studies) estimated an absolute risk difference (ARD) for in-hospital bloodstream infection mortality of 0.25 (95% confidence interval [CI], 0.17–0.32). Duration of antibiotic therapy (range, 4–29.7 vs 1–23.6 days) and length of hospital stay (range, 21–87 vs 15–43 days) were relatively higher for CPE-infected patients than for patients infected with carbapenem-susceptible pathogens. Most studies (82%) met >80% of their respective quality appraisal criteria.

Conclusions:

The risk of in-hospital mortality due to CPE bloodstream infection is considerably greater than carbapenem-susceptible bloodstream infection (ARD, 0.25; 95% CI, 0.17–0.32). Health outcome studies associated with CPE infection are focused on short-term (eg, in-hospital) outcomes; long-term sequelae and quality-of-life are not well studied.

Water entry of spheres with various contact angles
Authors: Speirs Nathan B. , Mansoor Mohammad M. , Belden Jesse , Truscott Tadd T.
Published: October 2019

It is well known that the water entry of a sphere causes cavity formation above a critical impact velocity as a function of the solid–liquid contact angle; Duez et al. (Nat. Phys., vol. 3 (3), 2007, pp. 180–183). Using a rough sphere with a contact angle of

$120^{\circ }$

, Aristoff & Bush (J. Fluid Mech., vol. 619, 2009, pp. 45–78) showed that there are four different cavity shapes dependent on the Bond and Weber numbers (i.e., quasistatic, shallow, deep and surface). We experimentally alter the Bond number, Weber number and contact angle of smooth spheres and find two key additions to the literature: (1) cavity shape also depends on the contact angle; (2) the absence of a splash crown at low Weber number results in cavity formation below the predicted critical velocity. In addition, we use alternate scales in defining the Bond, Weber and Froude numbers to predict the cavity shapes and scale pinch-off times for various impacting bodies (e.g., spheres, multidroplet streams and jets) on the same plots, merging the often separated studies of solid–liquid and liquid–liquid impact in the literature.
Leaders who empower: a gateway to radical innovation
Authors: Domínguez-Escrig Emilio , Mallén Broch Francisco Fermín , Lapiedra Alcamí Rafael , Chiva Gómez Ricardo
Published: October 2019

The main goal of the current study is to analyze the relationship between leaders' empowerment, radical innovation and organizational performance. A total of 300 Spanish companies participated in the study. In total, 600 valid questionnaires were obtained. Structural equations were used to validate the proposed hypotheses. Two different respondents in each company were selected to provide information. All the hypotheses proposed in the theoretical model were confirmed. This research provides empirical evidence of the relationship between leaders' empowerment and organizational performance, highlighting the mediation role played by radical innovation. Leaders who empower, promote radical innovation and, in turn, performance. To our knowledge, this is the first empirical study that analyzes the effect of leader's empowerment on radical innovation. Although in the former literature there are evidences of a positive relationship between empowerment and innovation, there are no studies that differentiate between innovation typologies.
A new Ladinian (Middle Triassic) mysidacean shrimp (Crustacea, Lophogastrida) from northern Italy and southern Switzerland
Authors: Larghi Cristiano , Tintori Andrea , Basso Daniela , Danini Gianluca , Felber Markus
Published: October 2019

Since the end of the nineteenth century, many paleontological studies have been developed on the Middle Triassic localities of the Monte San Giorgio area (Canton Ticino, Switzerland, and Lombardy, Italy). These localities were inscribed in 2003 and 2010 in the UNESCO World Heritage List due to their paleontological relevance. New crustaceans are here described from the Kalkschieferzone member of the upper Ladinian Meride Limestone, outcropping near Besnasca-Cà del Frate (Viggiù, Italy) and Meride (Mendrisio, Switzerland). Several hundred specimens of a new genus and new species of Lophogastrida, named here Vicluvia lombardoae, improve information on Triassic mysidaceans (sensu lato), a group of shrimp-like crustaceans presently including hundreds of species worldwide distributed in marine and freshwater environments. The paper discusses the relations between Vicluvia n. gen. and the other fossil genera belonging to the same family. Vicluvia lombardoae n. gen. n. sp. exhibits two dorsally vanishing transverse grooves with their branches regularly bending toward the posterior margin of the shield and a telson with a rounded and setose apex. It was probably a euryhaline species living in a transitional environment affected by frequent and ephemeral salinity variations. Middle Triassic taphonomic windows have preserved specimens of lophogastrids in shallow basins along the Tethys, from the present Alps to China as well as in the German Basin.

Phragmolites (Gastropoda) from the Late Ordovician of the Peruvian Altiplano
Authors: Ebbestad Jan Ove R. , Gutiérrez-Marco Juan Carlos
Published: October 2019

Phragmolites lissoni new species is described from 11 specimens found in the Sandbian Calapuja Formation near Calapuja in Peru. The deposits are part of the Central Andean Basin. This is the hitherto only systematically described Ordovician gastropod from Peru. The species is from a brachiopod-dominated siliciclastic sequence and is associated with bryozoans. Most specimens are preserved as external molds, but latex casts yield excellent details of shell ornamentation and are used as a basis for evaluating this feature in the genus. The characteristic ornamentation of Phragmolites should be called corrugated lamellae, and the individual elements on these should be referred to as flutes. A descriptive terminology for these is suggested. The development and shape of the corrugated lamellae and flutes could be biomechanical process. A second component in lamellar formation is the alternation between regular incremental growth and formation of a lamella. Phragmolites is mainly found in shallow-water carbonate facies from tropical latitudes in the Sandbian and a mid-latitude presence in Peru is unexpected. Brachiopods from the same section in Calapuja show affinities with faunas of the Mediterranean margin of Gondwana but also weak links with Avalonia. Phragmolites is found abundantly in deeper-water facies in Laurentia, and a broad tolerance to facies and temperature and possible planktotrophy might have allowed a wide geographical dispersal of the genus. The scant record of Ordovician gastropods in the Central Andean Basin precludes comparison with the disparate record of the Ordovician gastropod taxa from the Precordillera, which do not include Phragmolites.

The Role of Craft Breweries in Expanding (Local) Hop Production
Authors: Dobis Elizabeth A. , Reid Neil , Schmidt Claudia , Goetz Stephan J.
Published: October 2019

Hop production has expanded dramatically in recent years along with the number of local craft breweries, but to date the relationship between these two phenomena has not been explored systematically. Using a state-level pooled count data model with observations from 2007, 2012, and 2017, we examine the independent lagged effects of breweries on the number of hop farms and acres grown, holding constant fixed effects and key economic and geographic factors. Our results confirm that the number of breweries is associated with more hop production (farms and acres) five years later, while warmer temperatures and higher land prices discourage it.

Water supply systems in Cyrenaica during the Greek and Roman periods: Cyrene in context
Authors: Abdrbba Mohamed Omar M
Published: October 2019

This article investigates water supply systems in Cyrenaica during both the Greek and Roman periods. Beginning with some general information on water supply systems in Cyrenaica's other cities, it goes on to describe aqueducts and water cisterns recorded during the Cyrene Archaeological Surveys (CAS) around Cyrene in 2015 and 2017. The article explains how water was stored and delivered to the city of Cyrene in antiquity and offers a wider discussion on water distribution in Cyrene in the Greek era and how water supply systems developed through time, moving into the Roman period.
A road less travelled? The Society for Libyan Studies and the landscape archaeology of Libya's early civilisations
Authors: Mattingly David J.
Published: October 2019

This contribution explores a key dimension of the work of the Society for Libyan Studies concerning the archaeology of Libya's Protohistoric and early historic periods (broadly first millennium BC and first millennium AD). This primarily concerns the archaeology of rural landscapes (including the desert) and the investigation of the ancient Libyan populations that inhabited them. Taking an autobiographical approach, I review the contributions to developing research agendas made by a number of research projects that I have been involved in. The results collectively have advanced knowledge and understanding not only of this aspect of ancient Libyan society, but also have important implications for the construction of Libyan identity and the management of its heritage today. More broadly, they constitute an important contribution to wider re-evaluation of Maghribian and Saharan societies in the Iron Age and Roman periods.
Notes from Libya
Authors: Bennett Paul
Published: October 2019

‘Notes from Libya’ is a new regular feature of Libyan Studies, and follows the reports of the Society's Head of Mission. These reports were previously concerned with the organisation of fieldwork and administrative matters connected to obtaining permissions, visas and so on, and were recorded in the minutes of the Council meetings. However, they have recently taken on a new form, outlining the alarming developments in Libya, largely focussing on its heritage but also on the political and economic situation, which impacts on the management of Libya's ancient monuments and artefacts. The importance and historical interest of these reports now, however, merits a wider audience and a more formal record, so these accounts are now published in Libyan Studies.
When are occupiers in breach of their duty of care? The advantages of a systematic test
Authors: Dembour Marie-Bénédicte , Turner Juliet , Barrow Charles
Published: October 2019

Sixty years have passed since occupiers in England and Wales were placed under a statutory duty to keep visitors to occupied premises reasonably safe. The legislation, however, did not detail the exact operation of this duty of care. The case law, expected to fill in the gaps, has arguably developed without sufficient consistency and/or predictability. This apparent confusion can be remedied through applying a systematic test to the question of whether a breach of duty has occurred. The test follows the verification that the case falls within the field of occupiers’ liability because of the presence of a danger attributable to the state of the premises. It consists of three consecutive stages which ask: (1) whether the risk of injury was foreseeable; (2) whether the occupier could reasonably have been expected to have addressed this very particular risk; and (3) whether any remedial action the occupier actually took was appropriate.
Early nutrition in combination with polymorphisms in fatty acid desaturase gene cluster modulate fatty acid composition of cheek cells’ glycerophospholipids in school-age children

Published: October 2019

Variants in the human genes of fatty acid (FA) desaturase 1 (FADS1), 2 (FADS2) and 3 (FADS3) are associated with PUFA blood levels. We explored if maternal prenatal supplementation and children’s genetic variation in seventeen SNP of the FADS1, FADS2 and FADS3 gene cluster influence twenty-one of the most relevant cheek cells’ derived FA in glycerophospholipids (GPL-FA). The study was conducted in 147 Spanish and German mother–children pairs participating in the Nutraceuticals for a Healthier Life (NUHEAL) study at 8, 9 and 9·5 years. Linear and mixed model longitudinal regression analyses were performed. Maternal fish-oil (FO) or FO+5-methyltetrahydrofolate (5-MTHF) supplementation during pregnancy was associated with a significant decrease of arachidonic acid (AA) concentrations in cheek cell GPL in the offspring, from 8 to 9·5 years; furthermore, maternal FO+5-MTHF supplementation was associated with higher n-6 docosapentaenoic acid concentrations in their children at age 8 years. FADS1 rs174556 polymorphism and different FADS2 genotypes were associated with higher concentrations of linoleic and α-linolenic acids in children; moreover, some FADS2 genotypes determined lower AA concentrations in children’s cheek cells. It is suggested an interaction between type of prenatal supplementation and the offspring genetic background driving GPL-FA levels at school age. Prenatal FO supplementation, and/or with 5-MTHF, seems to stimulate n-3 and n-6 FA desaturation in the offspring, increasing long-chain PUFA concentrations at school age, but depending on children’s FADS1 and FADS2 genotypes. These findings suggest potential early nutrition programming of FA metabolic pathways, but interacting with children’s FADS polymorphisms.
The Life and Death of an Issue: Canadian Political Science and Quebec Politics
Authors: Rocher François
Published: October 2019

How has English-speaking Canadian political science conceived of the relationship between Quebec and Canada? Why has an issue that has been considered central for more than three decades become less attractive, if not marginal, within the discipline? The aim is to examine, from this example, the overlapping relationship between science and politics. The intent is also to show that Canadian political science has examined the Quebec/Canada relationship from four different angles: 1) its interest in Quebec politics was part of the urgency of the moment, based on a crisis that challenged the foundations of the political system; 2) it questioned the legitimacy of the sources of the dispute, namely the compatibility between the new expressions of Quebec nationalism with the presumed principles on which the Canadian political community had been founded; 3) Quebec nationalism also encouraged a reflection on the existence (or not) of “English Canada” as a sociological and political reality; 4) the combination of the first three factors caused the prescriptions for getting out of, or resolving, the crisis to evolve over time, to the point of rendering research on this issue obsolete.
Use your best endeavours to discover a sheltered and safe harbour
Authors: Park Robert W. , Stenton Douglas R.
Published: October 2019

On 24 May 1847, Sir John Franklin’s third expedition reported “All well”, but less than a year later, on 22 April 1848, the 129 sailors who had set out from Britain onErebusandTerrorhad been reduced to 105 survivors departing their frozen ships in a desperate attempt to escape the Arctic. At least 24 were so unhealthy that they would perish after having travelled little more than 100 km from the ships. By contrast, the small mortality rates on other contemporary Arctic expeditions, some of which stayed in the Arctic considerably longer, were consistent with the mortality rates in the Royal Navy worldwide. This paper explores the question of what difference caused so many of Franklin’s crew to die during their final months on-board the ships and in the initial stages of the escape attempt. From the perspective of cultural ecology, the most significant difference, and the ultimate cause of the catastrophe as it unfolded, was wintering in the ice pack. This distinguished the Franklin expedition from all of the other comparable overwintering expeditions, and precluded theErebusandTerrorcrews from hunting or fishing. That in turn led to nutritional deficiencies due to much greater reliance on stored provisions than other expeditions.
Physical injury and psychotic experiences in 48 low- and middle-income countries
Authors: Stickley A. , Sumiyoshi T. , Narita Z. , Oh H. , DeVylder J. E. , Jacob L. , Koyanagi A.
Published: October 2019

Background

Psychotic experiences (PEs) may be associated with injuries, but studies focusing specifically on low- and middle-income countries (LAMICs) are scarce. Thus, the current study examined the link between injuries and PEs in a large number of LAMICs.

Method

Cross-sectional data were used from 242 952 individuals in 48 LAMICs that were collected during the World Health Survey in 2002–2004 to examine the association between traffic-related and other (non-traffic-related) forms of injury and PEs. Multivariable logistic regression analysis and meta-analysis were used to examine associations while controlling for a variety of covariates including depression.

Results

In fully adjusted analyses, any injury [odds ratio (OR) 2.07, 95% confidence interval (CI) 1.85–2.31], traffic injury (OR 1.84, 95% CI 1.53–2.21) and other injury (OR 2.09, 95% CI 1.84–2.37) were associated with higher odds for PEs. Results from a country-wise analysis showed that any injury was associated with significantly increased odds for PEs in 39 countries with the overall pooled OR estimated by meta-analysis being 2.46 (95% CI 2.22–2.74) with a moderate level of between-country heterogeneity (I2 = 56.3%). Similar results were observed across all country income levels (low, lower-middle and upper-middle).

Conclusions

Different types of injury are associated with PEs in LAMICs. Improving mental health systems and trauma capacity in LAMICs may be important for preventing injury-related negative mental health outcomes.
Navigating at night: fundamental limits on the sensitivity of radical pair magnetoreception under dim light

Published: October 2019

Night-migratory songbirds appear to sense the direction of the Earth's magnetic field via radical pair intermediates formed photochemically in cryptochrome flavoproteins contained in photoreceptor cells in their retinas. It is an open question whether this light-dependent mechanism could be sufficiently sensitive given the low-light levels experienced by nocturnal migrants. The scarcity of available photons results in significant uncertainty in the signal generated by the magnetoreceptors distributed around the retina. Here we use results from Information Theory to obtain a lower bound estimate of the precision with which a bird could orient itself using only geomagnetic cues. Our approach bypasses the current lack of knowledge about magnetic signal transduction and processing in vivo by computing the best-case compass precision under conditions where photons are in short supply. We use this method to assess the performance of three plausible cryptochrome-derived flavin-containing radical pairs as potential magnetoreceptors.
The normative gap: mechanism design and ideal theories of justice
Authors: Hitzig Zoë
Published: October 2019

This paper investigates the relationship between economic theory and theories of justice in the design of public policy. In particular, it focuses on the role of mechanism design in policy contexts beset with issues of social, racial and distributive justice. Economists’ involvement in redesigning Boston’s algorithm for allocating K-12 students to public schools serves as an instructive case study. The paper draws on the distinction betweenideal theoryandnon-ideal theoryin political philosophy and the concept ofperformativityin economic sociology to argue that mechanism design can enact elaborate ideal theories of justice. Anormative gapthus emerges between the goals of the policymakers and the objectives of economic designs. As a result, mechanism design may obstruct stakeholders’ avenues for normative criticism of public policies, and serve as a technology of depoliticization.
Epidemiological profile and spectrum of neglected tropical disease eumycetoma from Delhi, North India

Published: October 2019

Mycetoma is a chronic granulomatous, suppurative and progressive inflammatory disease that usually involves the subcutaneous tissue and bones after traumatic inoculation of the causative organism. In India, actinomycotic mycetoma is prevalent in south India, south-east Rajasthan and Chandigarh, while eumycetoma, which constitutes one third of the total cases, is mainly reported from north India and central Rajasthan. The objective was to determine the epidemiological profile and spectrum of eumycetoma from a tertiary care hospital in Delhi, North India. Thirty cases of eumycetoma were diagnosed by conventional methods of direct microscopy, culture and species-specific sequencing as per standard protocol. The spectrum of fungal pathogens included Exophiala jeanselmei, Madurella mycetomatis, Fusarium solani, Sarocladium kiliense, Acremonium blochii, Aspergillus nidulans, Fusarium incarnatum, Scedosporium apiospermum complex, Curvularia lunata and Medicopsis romeroi. Eumycetoma can be treated with antifungal therapy and needs to be combined with surgery. It has good prognosis if it is timely diagnosed and the correct species identified by culture for targeted therapy of these patients. Black moulds required prolonged therapy. Its low reporting and lack of familiarity may predispose patients to misdiagnosis and consequently delayed treatment. Hence health education and awareness campaign on the national and international level in the mycetoma belt is crucial.
Exploring the Physical and Mental Health Challenges Associated with Emergency Service Call-Taking and Dispatching: A Review of the Literature
Authors: Smith Erin C. , Holmes Lisa , Burkle Frederick M.
Published: October 2019

Introduction:

Emergency service (ambulance, police, fire) call-takers and dispatchers are often exposed to duty-related trauma, placing them at increased risk for developing mental health challenges like stress, anxiety, depression, and posttraumatic stress disorder (PTSD). Their unique working environment also puts them at-risk for physical health issues like obesity, headache, backache, and insomnia. Along with the stress associated with being on the receiving end of difficult calls, call-takers and dispatchers also deal with the pressure and demand of following protocol despite dealing with the variability of complex and stressful situations.

Methods:

A systematic literature review was conducted using the MEDLINE, PubMed, CINAHL, and PsychInfo databases.

Results:

A total of 25 publications were retrieved by the search strategy. The majority of studies (n = 13; 52%) reported a quantitative methodology, while nine (36%) reported the use of a qualitative research methodology. One study reported a mixed-methods methodology, one reported an evaluability assessment with semi-structured interviews, one reported on a case study, and one was a systematic review with a narrative synthesis.

Discussion:

Challenges to physical health included: shift-work leading to lack of physical activity, poor nutrition, and obesity; outdated and ergonomically ill-fitted equipment, and physically confining and isolating work spaces leading to physical injuries; inadequate breaks leading to fatigue; and high noise levels and poor lighting being correlated with higher cortisol levels. Challenges to mental health included: being exposed to traumatic calls; working in high-pressure environments with little downtime in between stressful calls; inadequate debriefing after stressful calls; inappropriate training for mental-health-related calls; and being exposed to verbally aggressive callers. Lack of support from leadership was an additional source of stress.

Conclusion:

Emergency service call-takers and dispatchers experience both physical and mental health challenges as a result of their work, which appears to be related to a range of both operational and support-based issues. Future research should explore the long-term effects of these physical and mental health challenges.
Social support and psychosocial functioning in women after mastectomy
Authors: Janowski Konrad , Tatala Małgorzata , Jedynak Tomasz , Wałachowska Karolina
Published: October 2019

Objective

Social support has been reported as beneficial for the psychological functioning of people coping with a disease. The objective of this study was to verify whether levels of perceived social support are associated with psychosocial functioning in women who have had a mastectomy and whether specific types of social support are linked to specific indices of functioning.

Method

Seventy women with a history of mastectomy completed questionnaires measuring their psychosocial functioning as related to their health status: Disease-Related Appraisal Scale, Acceptance of Life with the Disease Scale and Beck Depression Inventory. All participants also completed a measure of perceived social support (Disease-Related Social Support Scale).

Results

Women who reported higher levels of perceived social support revealed statistically significantly lower levels of depressive symptoms, higher appraisals of their disease in terms of challenge and value, and lower appraisals of their disease in terms of obstacle/loss. Women with greater social support also revealed higher levels of acceptance of life with the disease compared to those with less social support. Regression analyses showed that spiritual support was the type of support that significantly accounted for the variance in the majority of functioning indices. Some indices of functioning were also significantly accounted for by emotional and instrumental support.

Significance of the results

The process of psychological adjustment to a life-threatening disease such as breast cancer depends on multiple variables; however, social support, including spiritual support, seems to be one significant contributor to this process.
Potentials, challenges, and limitations of the analysis of administrative data on vascular limb amputations in health care
Authors: Kolossváry Endre , Ferenci Tamás , Kováts Tamás
Published: October 2019

Summary. Although more and more data on lower limb amputations are becoming available by leveraging the widening access to health care administrative databases, the applicability of these data for public health decisions is still limited. Problems can be traced back to methodological issues, how data are generated and to conceptual issues, namely, how data are interpreted in a multidimensional environment. The present review summarised all of the steps from converting the claims data of administrative databases into the analytical data and reviewed the wide array of sources of potential biases in the analysis of such data. The origins of uncertainty of administrative data analysis include uncontrolled confounding due to a lack of clinical data, the left- and right-censored nature of data collection, the non-standardized diagnosis/procedure-based data extraction methods (i.e., numerator/denominator problems) and additional methodological problems associated with temporal and spatial analyses. The existence of these methodological challenges in the administrative data-based analysis should not deter the analysts from using these data as a powerful tool in the armamentarium of clinical research. However, it must be done with caution and a thorough understanding and respect of the methodological limitations. In addition to this requirement, there is a profound need for pursuing further research on methodology and widening the search for other indicators (structural, process or outcome) that allow a deeper insight how the quality of vascular care may be assessed. Effective research using administrative data is based on strong collaboration in three domains, namely expertise in claims data handling and processing, the clinical field, and statistical analysis. The final interpretations of results and the countermeasures on the level of vascular care ought to be grounded on the integrity of research, open discussions and institutionalized mechanisms of science arbitration and honest brokering.
Progress and Challenges in Quantifying Wildfire Smoke Emissions, Their Properties, Transport, and Atmospheric Impacts
Authors: Sokolik I. N. , Soja A. J. , DeMott P. J. , Winker D.
Published: October 2019

Wildfire is a natural and integral ecosystem process that is necessary to maintain species composition, structure, and ecosystem function. Extreme fires have been increasing over the last decades, which have a substantial impact on air quality, human health, the environment, and climate systems. Smoke aerosols can be transported over large distances, acting as pollutants that affect adjacent and distant downwind communities and environments. Fire emissions are a complicated mixture of trace gases and aerosols, many of which are short‐lived and chemically reactive, and this mixture affects atmospheric composition in complex ways that are not completely understood. We present a review of the current state of knowledge of smoke aerosol emissions originating from wildfires. Satellite observations, from both passive and active instruments, are critical to providing the ability to view the large‐scale influence of fire, smoke, and their impacts. Progress in the development of fire emission estimates to regional and global chemical transport models has advanced, although significant challenges remain, such as connecting ecosystems and fuels burned with dependent atmospheric chemistry. Knowledge of the impact of smoke on radiation, clouds, and precipitation has progressed and is an essential topical research area. However, current measurements and parameterizations are not adequate to describe the impacts on clouds of smoke particles (e.g., CNN, INP) from fire emissions in the range of representative environmental conditions necessary to advance science or modeling. We conclude by providing recommendations to the community that we believe will advance the science and understanding of the impact of fire smoke emissions on human and environmental health, as well as feedback with climate systems.
Comparison of the 2‐D and Quasi‐3‐D Geoelectric Models of the Ukrainian Eastern Carpathians and Their Link to the Tectonic Structure
Authors: Kováčiková Svetlana , Logvinov Igor , Tarasov Viktor
Published: October 2019

We present results of a study of the electrical conductivity distribution beneath the Ukrainian Eastern Carpathians where the Carpathian arc turns to the southeast and reaches the maximum curvature further in the Romanian territory. We have used the magnetotelluric and magnetovariational data in the period range of 1–6,000 s collected by geoelectric groups from several countries during deep induction experiments, which covered the studied area by a number of field stations clustered along profiles crossing the Carpathian arc. In this work, we compare the 2‐D and quasi‐3‐D thin sheet inverse models, which allow us to constrain both the geometry and electrical properties of the anomalous conductivity structures beneath the Carpathians. Comparison of the inverse results with the Carpathians tectonics indicates that the Carpathian conductivity anomaly within the Polish and Slovak territory is located approximately between the Magura nappe front and the Pieniny Klippen Belt. In Ukraine, where the Magura nappe narrows and disappears, the anomaly reaches the front of the Outer Carpathians. The resulting quasi‐3‐D model of the conductivity structure beneath the Carpathians is compared with other geophysical and geological data within the region. The relation of the position of the conductors to the heat flow models and to location of the earthquakes sources indicates possible geological mechanisms, such as saline pore fluids, thin films of grain boundary graphite, or partial melting, connected with recent activation zones.

Coccolithophores are a biogeochemically important calcifying group of phytoplankton that exert significant influence on the global carbon cycle. They can modulate the air‐sea flux of CO2 through the processes of photosynthesis and calcification and, as one of the primary contributors to the oceanic particulate inorganic carbon (PIC) pool, promote the export of organic carbon to depth. Here we present the first interannually resolved, global analysis of PIC standing stock. Average, global PIC standing stock in the top 100 m is estimated to be 27.04 ± 4.33 Tg PIC, with turnover times of ~7 days, which suggests PIC is likely removed by active processes such as grazing or rapid sinking, mediated through biogenic packaging (i.e., fecal pellets). We find that the Southern Hemisphere plays a significant role in the variability in PIC inventories and that interannual variability in PIC standing stock is driven primarily by variability in the midlatitude oceanic gyres and regions within the Great Calcite Belt of the Southern Ocean. Our results provide a framework against which future changes in global PIC standing stocks may be assessed.
Experimentally Derived Thresholds for Windblown Sand on Mars

Aeolian sand transport frequently occurs on Mars despite wind speeds rarely exceeding predicted thresholds for motion. This dissonance is problematic for understanding aeolian processes and the resulting geomorphologic responses in contemporary and ancient atmospheres. To address the apparent discrepancy between speeds required to initiate sand motion and transport observed from orbital and in situ observations, we conducted a series of wind tunnel experiments at Martian atmospheric pressures and used buoyancy as the similitude parameter to simulate the force required to initiate particle motion on Mars. Shear velocities were derived from velocity profiles corresponding to the onset of sporadic transport, which can induce downwind cascading motion. Here, we find that threshold shear velocities are slower than previously thought by a factor of 1.6 to 2.5. Measured wind speeds on Mars exceed our observed thresholds, thus offering one mechanism behind the dissonance between observations of transport below previous thresholds of motion.

Large numbers of earthquakes occur in subduction zones that are marked by dipping, narrow high seismic velocity slabs. The existence of these fast velocity slabs can cause serious earthquake mislocation problems that can bias estimates of seismic travel time residuals. This can affect the recovery of subducting slabs in tomography as well as introduce significant artifacts into lower mantle structure in tomography models. In order to better account for known subducting slabs, we performed a new P and S wave joint tomography inversion incorporating a three‐dimensional thermal model of subducting slabs in the starting model. In addition, velocity and source locations were inverted for simultaneously. Our new P and S models feature higher‐amplitude subducting slabs compared with previous global tomography results. The S to P heterogeneity ratio based on the new tomography model indicates that thermal elastic effects alone cannot explain all the heterogeneities in the lower mantle. Much of the observed abnormal S to P heterogeneity ratio can be explained by anelastic effects, the spin transition, and phase transitions of bridgmanite to post‐perovskite in the lower mantle.
A Joint Analysis of GPS Displacement and GRACE Geopotential Data for Simultaneous Estimation of Geocenter Motion and Gravitational Field

Gravitational potential data from GRACE are being used to study mass redistribution within and between the atmosphere, hydrosphere, cryosphere, and solid Earth. The GRACE data are made available in a reference frame with its origin at the center of mass of the Earth system (geocenter) while many other geophysical models and data sets refer to a reference frame attached to the Earth's surface. Changes in the offset between these reference frames (geocenter motion) must be accounted for when GRACE data are used to quantify surface mass changes. In this study, we developed a technique for co‐estimation of geocenter motion and gravitational potential field seamlessly from degree 1 to 90 by simultaneously inverting a set of globally‐distributed GPS displacement time series and the temporally‐varying GRACE gravity data. We found that the effect of geocenter motion was evident particularly in the GPS time series of horizontal displacements. Our estimates of geocenter motion are most consistent with the Satellite Laser Ranging (SLR) results within 1 mm in X and Z components and a submillimeter in Y component, when compared to monthly variability averaged over the period of 2003–2016. The overall magnitude of the degree‐1 (l = 1) surface mass load is estimated to be ~3 cm in equivalent water height annually migrating south‐westward from Europe (December–January) to the South Pacific (June–July). Our results also show that dense GPS network data improve water storage recovery in major river basins in the United States and Europe by contributing significantly to the recovery of higher‐degree (l ≥ ~20) geopotential coefficients.
The 2019 New Year Stratospheric Sudden Warming and Its Real‐Time Predictions in Multiple S2S Models

Published: October 2019

Using multiple data sources, favorable conditions for the 2019 SSW event and its predictive skill from 11 subseasonal to seasonal (S2S) forecast models are explored in this study. This mixed‐type (displacement to split) SSW event occurred under moderate El Niño, easterly quasi‐biennial oscillation (QBO) together with solar minimum, and phases 4–6 of the Madden‐Julian oscillation (MJO). A strong positive PNA formed and developed in the troposphere before this SSW event, which is associated with enhanced and wave‐1‐dominated eddy heat flux. The predictive limit to this SSW onset is beyond 18 days in most S2S models, longer than the average predictive limit in existing literature. This high predictive skill may originate from the favorable initial conditions (QBO, MJO) and boundary conditions (moderate El Niño, solar minimum). Although some difference in the predictability of the 2019 SSW onset is found between models, most models well forecast its onset at a lead time of 18 days. More than 50% of the ensemble members initialized on 13 December forecast the zonal wind reversal, and the anomaly correlation for tropospheric heights during the SSW onset even exceed 0.7 in the multimodel ensemble (MME). In contrast, the predictability of the wave‐3 and wave‐2 pulses after the SSW onset, responsible for the standing split of the stratospheric polar vortex, is low in the forecast MMEs initialized before the SSW onset. It is a challenge for MMEs initialized before the SSW onset to well forecast the vortex splitting and its persistence 10–20 days after the SSW onset.

In this study, we develop statistical relationships between radar observables and drop size distribution properties in different latitude bands to inform radar rainfall retrieval techniques and understand underpinning microphysical reasons for differences reported in the literature between satellite mean zonal rainfall products at high latitudes (up to a factor 2 between products over ocean). A major assumption in satellite retrievals is the attenuation‐reflectivity relationships for convective and stratiform precipitation. They are found to systematically produce higher attenuation than our relationships with all latitudes included or within individual latitude bands (except in the tropics). The scatter around fitted curves approximating the radar reflectivity‐mass‐weighted diameter Dm relationship and the dual‐frequency ratio (ratio of Ka‐ to Ku‐band reflectivities)‐Dm relationships is found to be large and of the same magnitude. This result suggests that the added value of two radar frequencies to improve the Dm retrieval from space seems limited. In contrast, the relationship between Dm and the attenuation/reflectivity ratio is robust and not dependent on latitude. Direct relationships between rainfall and either reflectivity or attenuation are also found to be very robust. Attenuation‐reflectivity, Dm‐reflectivity, and rainfall rate‐reflectivity relationships in the Southern Hemisphere high latitude and Northern Hemisphere polar latitude bands are fundamentally different from those at other latitude bands, producing smaller attenuation, much larger Dm, and lower rainfall rates. This implies that specific relationships need to be used for these latitude bands in radar rainfall retrieval techniques using such relationships.
