A high-resolution paleolimnological study of climate and human impacts on Lac Noir, Québec, over the past 1000 yr
Authors: Neil Karen , Gajewski Konrad 
Published: November 2018

AbstractDiatom assemblages in lake sediments of Lac Noir, southwestern Québec, were studied at a resolution of 10 yr to determine principal drivers of primary producers for the past ~1000 yr. Generalized additive modeling revealed strong links between broadscale climate intervals of the late Holocene, forest composition, and diatom flora. During the Medieval Warm Period (~AD 1200) and onset of the Little Ice Age (~AD 1450), increases in Tabellaria flocculosa str. IIIp at the expense of Discostella stelligera reflected low lake productivity. At AD 1630, an abrupt shift to cooler temperatures and dry conditions triggered a decline in hemlock (Tsuga), replaced by disturbance and cool-adapted taxa. Greater nutrient availability and soil erosion in the catchment led to a corresponding and rapid increase in diatoms with higher optima for nitrogen, such as Asterionella formosa and Fragilaria crotonensis. After AD 1870, an increase in pollen of taxa associated with disturbances signaled the arrival of Euro-Canadians, and associated nutrient inputs to the lake triggered increases in Stephanodiscus minutulus and Achnanthidium minutissimum. Overall results of the study indicate that climate played an important underlying role in lake-ecosystem dynamics; however, disturbances affecting forest composition had more direct influences on the diatom communities of Lac Noir.

Published: November 2018

ABSTRACTRadiocarbon (14C) is a key radionuclide in the assessment of the safety of underground geological disposal facilities for radioactive wastes, and the understanding of the 14C behavior in stainless steel may lead to a re-evaluation of the near-surface repository for the disposal of wastes containing this radionuclide in high concentrations. To achieve this objective, leaching experiments were planned for two different scenarios. The first is where the leaching solution, NaOH solution of pH ca. 12 in aerobic conditions, simulates the expected conditions in a cement-based near-surface repository over long time periods. The other one uses an acid solution of 1M H3PO4, which has been proved as a high efficiency chemical removal agent of 14C in graphite. The development of both analytical methods and protocols to measure the release of 14C from the activated steel samples and the speciation in the aqueous and gaseous phase has been undertaken as part of the EC CAST (CArbon-14 Source Term) project. Analytical methods, suitable for identifying and quantifying low molecular weight organic molecules, comprise ion chromatography (IC) and gas chromatography coupled to mass spectrometry (GC-MS); they are described for aqueous and gaseous samples, respectively. In this paper the preparation of leaching experiments to measure the release of 14C and the results obtained are described.
WITCHCRAFT, THE PRESS, AND CRIME IN IRELAND, 1822–1922
Authors: SNEDDON ANDREW , FULTON JOHN 
Published: November 2018

AbstractDrawing on witchcraft cases reported in newspapers and coming before Ireland's courts, this article argues that witch belief remained part of Protestant and Catholic popular culture throughout the long nineteenth century. It is shown that witchcraft belief followed patterns established in the late eighteenth century and occasioned accusations that arose from interpersonal tensions rather than sectarian conflict. From this article, a complex picture emerges of the Irish witches and their ‘victims’, who are respectively seen to have fought accusation and bewitchment using legal, magical, physical, and verbal means. In doing so, the contexts are revealed in which witchcraft was linked to other crimes such as assault, slander, theft, and fraud in an era of expansion of courts and policing. This illustrates how Irish people adapted to legal changes while maintaining traditional beliefs, and suggests that witchcraft is an overlooked context in which interpersonal violence was exerted and petty crime committed. Finally, popular and elite cultural divides are explored through the attitudes of the press and legal authorities to witchcraft allegations, and an important point of comparison for studies of witchcraft and magic in modern Europe is established.

AbstractThe objective of the current study was to evaluate the effects of sugarcane and maize silage mixturev.maize silage in diets of Holstein cows and investigate performance under two environmental conditions. The cows were placed in freestalls, with individuals and stalls assigned to one of four treatments according to a replicated 4 × 4 Latin square design with 20-day periods divided into 11 days of adaptation (wash-out period) and 9 days of collection. Treatments were arranged in a 2 × 2 × 2 factorial design: total diets (maize silage (MS-based diet), the roughage mixture (RM-based diet, sugarcane : maize silage, 500 : 500 g/kg DM) plus concentrate); environmental conditions (with (W) and without (Wo) fan and nebulizers); and measurement times (09.40 and 14.00 h). The temperature and relative humidity was higher at 14.00 h and contributed to increased temperature-humidity index (76.6, Wv.75.9, Wo). Feed dry matter intake (DMI) was similar between diets (20.2 kg/day), but milk production and feed efficiency were lower with RM. Under W conditions, higher fat content and total solids of milk were observed with the RM-based diet, while crude protein and lactose were higher with MS. The Wo conditions increased body surface temperature (BS) in cows fed MS. The rectal temperature (RT) was higher with RM. The BS, RT and respiratory rate were higher at 14.00 h (34.9, 38.6 °C and 58.2 breaths/min) than at 09.40 h. The RM-based diet maintained DMI and milk composition, but not milk production. The use of the cooling system led to higher DMI and feed N efficiency use.
Never say never: circumventing a contraindication to control apnoea-induced epileptic events with a mandibular advancement device
Authors: Fenton J E , Fitzgerald C , Dillon P J , O'Shea D 
Published: November 2018

AbstractBackgroundThe benefit of mandibular advancement devices in patients with sleep-disordered breathing and as a potential option for obstructive sleep apnoea syndrome is well recognised. Their use in the setting of epilepsy or other seizure disorders is typically contraindicated.Case reportA 48-year-old patient with a history of poorly controlled epilepsy and obstructive sleep apnoea syndrome was referred for ENT review for possible tracheostomy. The patient was wheelchair-bound with 24-hour continuous positive airway pressure, but sleep studies demonstrated persistent, severe episodes of apnoea and notable sleep disturbance. Sleep nasendoscopy demonstrated marked improvement on capnography with the laryngeal mask airway in situ, and this was maintained with mandibular advancement using jaw thrust following removal of the laryngeal mask airway. A mandibular advancement device was subsequently trialled; this had no subjective benefit for the patient, but the seizures resolved and control of apnoea was achieved with the combination of a mandibular advancement device and continuous positive airway pressure.ConclusionThis paper highlights a novel application of mandibular advancement devices, used in combination with continuous positive airway pressure, which resulted in complete resolution of sleep deprivation and apnoea-induced epileptic events.
Incidental mastoiditis on magnetic resonance imaging scans: clinical relevance and cost implications
Authors: Abbas Y , Yuen H S , Trinidade A , Watters G 
Published: November 2018

AbstractObjectivesTo determine: (1) the incidence of incidental ‘mastoiditis’ reported on magnetic resonance imaging scans performed in patients with asymmetrical sensorineural hearing loss and/or unilateral tinnitus; (2) how many of those patients have actual otological pathology and/or require treatment; and (3) the financial implications of such a reporting practice.MethodRetrospective case series.ResultsBetween October 2015 and November 2016, 500 patients underwent magnetic resonance imaging of the internal auditory meatus to rule out cerebellopontine angle lesions. There was an incidental finding of increased mastoid signalling in 5.8 per cent (n= 29), of which 20.7 per cent (6 of 29) were reported as bilateral cases. The diagnosis of ‘mastoiditis’ was found in 39.7 per cent (29 of 73). None of these patients had any pathology identified clinically. Other significant pathology was identified in a further 8.8 per cent (n= 44).ConclusionThe diagnosis of mastoiditis is primarily clinical. An incidental finding of high signalling in the mastoid region on magnetic resonance imaging is highly unlikely to represent actual clinical disease. In patients who are scanned for other reasons and who do not complain of otological symptoms, such findings are unlikely to require otolaryngology input.

AbstractBackgroundEosinophils are the principal effector cells involved in the pathogenesis of allergic rhinitis. Cell numbers increase in non-allergic rhinitis patients with eosinophilia, aspirin hypersensitivity and nasal polyposis, as well as in allergic rhinitis patients. Exfoliative nasal cytology can be used in the differential diagnosis of allergic rhinitis.ObjectiveTo evaluate nasal eosinophilia in nasal smears of patients with mild, persistent and intermittent allergic rhinitis.MethodsThe study comprised 60 patients with allergic rhinitis and 20 healthy volunteers. The patients were divided into intermittent and persistent allergic rhinitis groups. Nasal smear status, eosinophil numbers and Total Nasal Symptom Scores were compared.ResultsNasal smear results were pathological in 40 of 60 allergic rhinitis patients, which was significantly higher than the rate in controls. The mean nasal eosinophilia score was significantly higher in the intermittent allergic rhinitis than in the persistent allergic rhinitis group (p= 0.029). There was a positive correlation between nasal eosinophilia score and Total Nasal Symptom Score (r = 0.652;p< 0.05) in persistent allergic rhinitis and intermittent allergic rhinitis patients.ConclusionThe nasal smear test is inexpensive, objective and simple to perform, and should be part of the diagnostic investigation.

Authors: Techetach Mohamed , Ajana Rabia , Saoud Younes 
Published: November 2018

AbstractReproductive biology of Atlantic chub mackerel (Scomber colias) was studied based on samples from commercial catches in M'diq Bay, Morocco. Females predominated in the total catch (54%), their size at first maturity being 19.19 ± 0.43 cm TL. A minimum landing size (MLS) of 21 cm is suggested. The oocyte size frequency distribution and histological analysis confirmed that S. colias is a species with an indeterminate fecundity. The batch fecundity was estimated as 18,452–131,642, with a mean of 60,022 oocytes. The relative batch fecundity was 157–360, with a mean of 279 eggs g−1.
Faraway Siblings, So Close: Ephemeral conviviality across the Wakhan divide
Authors: MOSTOWLANSKY TILL 
Published: November 2018

AbstractIn this article, I set out to explore the possibility of a shared life between two places in the highlands of Pakistan and Tajikistan—a region dissected by Afghanistan's narrow Wakhan corridor, by present-day nation-state boundaries, by historical divisions between Central and South Asia, and by a former Cold War frontier. Moving away from a take on conviviality as specifically tied to urban spaces and face-to-face encounters, I attempt to trace the processes that determine the coming and going of shared modes of being. In doing so, I first situate the two places—Karimabad and Khorog—in their respective post-Cold War borderlands and point to their historically ambivalent status as ‘marginal’ places at the frontier, culturally diverse ‘hubs’, and sites of globalization. Then I analyse the historical build-up—material and ideological—that led to the establishment of specific forms of connection and disconnection between the two places. In the last part of the article, I discuss how people in and from Karimabad and Khorog seek out opportunities to attain shared instances of common sociality, which often remain ephemeral and subject to regimes of power. Finally, I argue that the cases of these two ‘marginal hubs’ highlight the importance of looking beyond the conventional ‘imperial centre’ when debating the dynamics that lead people to desire, create, and abandon ties across difference.

AbstractThe objective of this study was to identify species ofAngiostrongylusspp. infecting wild carnivores in Southern Brazil, as well as to describe gross and histopathological findings associated with the infection. Necropsy was conducted in 16 wild carnivores parasitized byAngiostrongylusspp. Analysed lungs revealed multifocal dark-red areas of consolidation; in one case, multifocal firm white nodules spread in all pulmonary lobes were observed. In one animal, a focally extensive area of malacia associated with haemorrhage was noted in the encephalon. Histologically, multifocal granulomatous pneumonia or bronchopneumonia, associated with eggs and larvae in blood vessels, lung interstitium, alveoli, and sometimes in bronchi and bronchioles was observed. Adult nematodes were seen within blood vessels. The lesion observed in the brain was characterized as a focally extensive area of malacia associated with gitter cells, haemorrhage, thrombosis and a free intralesional larva. Through molecular techniques, seven positive samples ofAngiostrongylus cantonensiswere obtained, including the brain sample, and a positive sample ofAngiostrongylus vasorum-like, all inCerdocyon thous. The positive sample forA. vasorumshowed 97% similarity with sequences deposited in GenBank, suggesting a new species or subspecies ofAngiostrongylussp. Infection ofLycalopex gymnocercusbyAngiostrongylusspp. was confirmed by histological evaluation.
Meta-regulation meets Deliberation: Situating the Governor within NHS Foundation Trust Hospitals
Authors: MILLAR ROSS , FREEMAN TIM , MANNION RUSSELL , DAVIES HUW T. O. 
Published: November 2018

AbstractNHS Foundation Trust (FT) hospitals in England have complex internal governance arrangements. They may be considered to exhibit meta-regulatory characteristics to the extent that governors are able to promote deliberative values and steer internal governance processes towards wider regulatory goals. Yet, while recent studies of NHS FT hospital governance have explored FT governors and examined FT hospital boards to consider executive oversight, there is currently no detailed investigation of interactions between these two groups. Drawing on observational and interview data from four case-study sites, we trace interactions between the actors involved; explore their understandings of events; and consider the extent to which the proposed benefits of meta-regulation were realised in practice. Findings show that while governors provided both a conscience and contribution to internal and external governance arrangements, the meta-regulatory role was largely symbolic and limited to compliance and legitimation of executive actions. Thus while the meta-regulatory ‘architecture’ for governor involvement may be considered effective, the soft intelligence gleaned and operationalised may be obscured by ‘hard’ performance metrics which dominate resource-allocation processes and priority-setting. Governors were involved in practices that symbolised deliberative involvement but resulted in further opportunities for legitimising executive decisions.
Sparse Highly Connected Spanning Subgraphs in Dense Directed Graphs
Authors: KANG DONG YEAP 
Published: November 2018

Mader proved that every strongly k-connected n-vertex digraph contains a strongly k-connected spanning subgraph with at most 2kn - 2k2 edges, where equality holds for the complete bipartite digraph DKk,n-k. For dense strongly k-connected digraphs, this upper bound can be significantly improved. More precisely, we prove that every strongly k-connected n-vertex digraph D contains a strongly k-connected spanning subgraph with at most kn + 800k(k + Δ(D)) edges, where Δ(D) denotes the maximum degree of the complement of the underlying undirected graph of a digraph D. Here, the additional term 800k(k + Δ(D)) is tight up to multiplicative and additive constants. As a corollary, this implies that every strongly k-connected n-vertex semicomplete digraph contains a strongly k-connected spanning subgraph with at most kn + 800k2 edges, which is essentially optimal since 800k2 cannot be reduced to the number less than k(k - 1)/2.We also prove an analogous result for strongly k-arc-connected directed multigraphs. Both proofs yield polynomial-time algorithms.
The 2016 Election: Like 1888 but not 1876 or 2000
Authors: Barthélémy Fabrice , Martin Mathieu , Piggins Ashley 
Published: November 2018

ABSTRACTDonald J. Trump won the 2016 US presidential election with fewer popular votes than Hillary R. Clinton. This is the fourth time this has happened, the others being 1876, 1888, and 2000. In earlier work, we analyzed these elections (and others) and showed how the electoral winner can often depend on the size of the US House of Representatives. This work was inspired by Neubauer and Zeitlin (2003, 721–5) in their paper, “Outcomes of Presidential Elections and the House Size.” A sufficiently larger House would have given electoral victories to the popular vote winner in both 1876 and 2000. An exception is the election of 1888. We show that Trump’s victory in 2016 is like Harrison’s in 1888 and unlike Hayes’s in 1876 and Bush’s in 2000. This article updates our previous work to include the 2016 election. It also draws attention to some of the anomalous behavior that can arise under the Electoral College.

AbstractObjectiveThe present study aimed to determine the relationship among food insecurity, social support and mental well-being in sub-Saharan Africa, a region presenting the highest prevalence of severe food insecurity and a critical scarcity of mental health care.DesignFood insecurity was measured using the Food Insecurity Experience Scale (FIES). Social support was assessed using dichotomous indicators of perceived, foreign perceived, received, given, integrative and emotional support. The Negative and Positive Experience Indices (NEI and PEI) were used as indicators of mental well-being. Multilevel mixed-effect linear models were applied to examine the associations between mental well-being and food security status, social support and their interaction, respectively, accounting for random effects at country level and covariates.ParticipantsNationally representative adults surveyed through Gallup World Poll between 2014 and 2016 in thirty-nine sub-Saharan African countries (n 102 235).ResultsThe prevalence of severe food insecurity was 39 %. The prevalence of social support ranged from 30 to 72 % by type. In the pooled analysis using the adjusted model, food insecurity was dose-responsively associated with increased NEI and decreased PEI. Perceived, integrative and emotional support were associated with lower NEI and higher PEI. The differences in NEI and PEI between people with and without social support were the greatest among the most severely food insecure.ConclusionsBoth food insecurity and lack of social support constitute sources of vulnerability to poor mental well-being. Social support appears to modify the relationship between food security and mental well-being among those most affected by food insecurity in sub-Saharan Africa.
Getting the food list ‘right’: an approach for the development of nutrition-relevant food lists for household consumption and expenditure surveys

Published: November 2018

AbstractObjectiveThe present paper aimed to demonstrate how 24 h dietary recall data can be used to generate a nutrition-relevant food list for household consumption and expenditure surveys (HCES) using contribution analysis and stepwise regression.DesignThe analysis used data from the 2011/12 Bangladesh Integrated Household Survey (BIHS), which is nationally representative of rural Bangladesh. A total of 325 primary sampling units (PSU=village) were surveyed through a two-stage stratified sampling approach. The household food consumption module used for the analysis consisted of a 24 h open dietary recall in which the female member in charge of preparing and serving food was asked about foods and quantities consumed by the whole household.SettingRural Bangladesh.ParticipantsA total of 6500 households.ResultsThe original 24 h open dietary recall data in the BIHS were comprised of 288 individual foods that were grouped into ninety-four similar food groups. Contribution analysis and stepwise regression were based on nutrients of public health interest in Bangladesh (energy, protein, fat, Fe, Zn, vitamin A). These steps revealed that a list of fifty-nine food items captures approximately 90 % of the total intake and up to 90 % of the between-person variation for the key nutrients based on the diets of the population.ConclusionsThe study illustrates how 24 h open dietary recall data can be used to generate a country-specific nutrition-relevant food list that could be integrated into an HCES consumption module to enable more accurate and comprehensive household-level food and nutrient analyses.
