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

AbstractThe 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

AbstractSince 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.UUID: http://zoobank.org/1623e8f9-2ceb-4cd6-bcbe-4f05a873e1ff
Phragmolites (Gastropoda) from the Late Ordovician of the Peruvian Altiplano
Authors: Ebbestad Jan Ove R. , Gutiérrez-Marco Juan Carlos 
Published: October 2019

AbstractPhragmolites 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.UUID: http://zoobank.org/References/fbd7a43e-a610-42fd-a31d-b1a16fa69c9b
The Role of Craft Breweries in Expanding (Local) Hop Production
Authors: Dobis Elizabeth A. , Reid Neil , Schmidt Claudia , Goetz Stephan J. 
Published: October 2019

AbstractHop 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

AbstractThis 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

AbstractThis 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

Abstract‘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

AbstractSixty 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

AbstractVariants 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

AbstractHow 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

Published: October 2019

AbstractOn 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.

Published: October 2019

AbstractBackgroundPsychotic 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.MethodCross-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.ResultsIn 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).ConclusionsDifferent 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

Abstract
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

AbstractThis 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.

Abstract
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

AbstractIntroduction: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.
