The association between particulate matter 2.5 exposure and children with autism spectrum disorder
Authors: Geng Ruihua , Fang Suqin , Li Guizhi 
Published: May 2019

AbstractObjectiveParticulate matter (PM) as an environmental pollutant is suspected to be associated with autism spectrum disorder (ASD). The aim of this study was to assess whether exposures to PM2.5 during the first three years of life in relation to the risk and degree of the severity of ASD.MethodsA total of two hundred and ninety‐seven 3–6 years old Chinese children (99 confirmed autism cases and 198 their age‐gender matched control subjects) were included. Children's exposures to PM2.5 (particulate matter with aerodynamic diameter <2.5 μm) during the first three years after birth were estimated. Logistic regression analysis was used to examine the PM2.5‐ASD association.ResultsThe mean levels of PM2.5 exposures in ASD and typical developmental children during the first three years of life were 89.8[standard deviations (SD): 6.1] μg/m3 and 87.3(6.6) μg/m3, respectively (p = 0.002). A statistically significant positive correlation was found between the serum levels of PM2.5 and the Childhood Autism Rating Scale (CARS) score indicating severity of autism (r = 0.259; p = 0.010). Based on the receiver operating characteristic (ROC) curve, the optimal cutoff value of PM2.5 levels as an indicator for auxiliary diagnosis of ASD was projected to be 89.5ug/m3, which yielded a sensitivity of 65.4% and a specificity of 63.2%, with the area under the curve at 0.61 (95% confidence intervals [CIs], 0.54−0.68; P < 0.001). Multivariate analysis models were used to assess ASD risk according to PM2.5 quartiles (the lowest quartile [Q1] as the reference), with the adjusted odds ratios (ORs) (95% CIs) were recorded. As shown in the Table 2, the 3rd and 4th quartile of PM2.5 were compared against the Q1, and the risks were increased by 103% (OR = 2.03; 95%CI: 1.13–5.54; p = 0.015) and 311% (4.15; 2.04–9.45; p = 0.002), respectively.ConclusionsTo conclude, the evidence from this study allowed us to conclude that there was an association between PM2.5 exposure and ASD risk and severity.

Published: May 2019

ObjectiveDetermine current opioid prescribing patterns for adult procedures within an academic Otolaryngology‐Head and Neck Surgery training program in order to establish a general guideline and more uniform approach to narcotic prescribing practices.MethodsThe is a prospective, single‐center pilot study. An online, anonymous survey was sent to all members of the Otolaryngology‐Head and Neck Surgery training program at Medical University of South Carolina including residents, fellows, and attending surgeons, and advanced practice providers (APP). The survey consisted of questions including demographics, most commonly prescribed analgesic and the average number of opioid tablets prescribed post‐operatively for eleven of the most common adult procedures within Otolaryngology.ResultsForty‐two participants responded to the survey. Of the 42 respondents, 20 were attending surgeons, 11 junior level residents (year 1–3), 6 senior level residents (year 4–5), and 5 A.P.P.s. The most commonly prescribed narcotic was hydrocodone‐acetaminophen with 83.3% (35/42) of respondents prescribing this medication. Tonsillectomy or uvulopalatopharyngoplasty had the highest average number of tablets prescribed at 32.3 (Range: 5 to 90). Neck dissection, parotidectomy, and thyroidectomy procedures all averaged over 20 tablets. Direct laryngoscopy opioid dose was the lowest at 4.8 tablets (range 0–20). Opioid prescriptions by surgery were broken down by provider class with only septoplasty showing a significant difference with attending physicians prescribing an average of 20 tablets vs 14.1 tablets for residents (P = 0.034).ConclusionWe believe there remains an unacceptably high variability in current opioid prescribing patterns within otolaryngology especially within more painful procedures. Establishment of standardized post‐operative narcotic guidelines is warranted.
The NorthernZanj, Demadim, Yamyam, Yam/Yamjam,Habasha/Ahabish,Zanj-Ahabish, andZanj ed-Damadam– The Horn of Africa between the Ninth and Fifteenth Centuries
Authors: Ayana Daniel 
Published: May 2019

Abstract:This article argues that historians will have a new understanding of northeast and east Africa if they recall the medieval meaning of the termsZanjandAhabish, orHabasha. Before the fifteenth century the termZanjincluded the diverse populations of northeast Africa, so should not be exclusive of the populations of coastal east Africa. Likewise,HabashaorAhabishwas not confined to the peoples of the northern Horn but included the diverse peoples of coastal east Africa. Uncovering older meanings ofZanjandAhabishhelps to identify elusive groups of ancient northeast Africans referred to as northernZanj, Zanj-Ahabish, Ahabish, andDamadim. For identification, this article presents three types of historical data overlooked in the sources. The first consists of the interchangeable names northernZanj,Damadim, Ahabish, Zanj-Ahabish, andZanj ed-Damadimto recast the termZanjand identify theDamadimorYamyam.The second is the broadly inclusive meaning before the fifteenth century of the termHabasha. The third is the reported eloquence in theirButtaaceremony of the northernZanj, and the institutional setting of theButtaawithin the OromoGadaasystem.
Radical Steele: Popular Politics and the Limits of Authority
Authors: Marshall Ashley 
Published: May 2019

AbstractIn modern critical imagination, Richard Steele is almost always seen as Joseph Addison's friend and collaborator, as half of the periodical essay-writing team devoted to the promotion of civility, urbanity, and a moral and well-mannered lifestyle. Scholars focus almost exclusively on the Tatler, the Spectator, and Steele's sentimental drama, The Conscious Lovers (1722), virtually ignoring his substantial canon of party journalism and pamphlets. Partly because of Steele's bitter and extensive quarrel with Jonathan Swift—or because most scholars assume that Swift got the best of him—he is now rarely taken seriously as a political player in late Stuart and early Hanoverian England. This essay focuses on Steele the party writer—and especially on his attitude toward religio-political authority and the sanctity of vox populi. Though Steele is now described as (like Addison) “not so enthusiastic about the potential for public politics,” he was for excellent reasons regarded by contemporaries as a writer not only trying to politicize the people but actually succeeding in doing so. This essay attempts to recontextualize Steele's polemical contributions; he has been read alongside Addison and other Whig wits, but he rarely figures in discussions of the history of political ideas in early eighteenth-century England, in discussions of debates about authority, resistance, and the nature of obligation, about public religion and liberty of conscience, the political implications of heterodoxy, and the use of reason as a challenge to dogmatic clerical authority.
Ten Demi-Culverins for Aldeburgh: Whitehall, the Dunkirkers, and a Suffolk Fishing Community, 1625–1630
Authors: Cogswell Thomas 
Published: May 2019

AbstractHistorians have not paid close attention to the activities of freebooters operating out of Dunkirk in the late 1620s. This essay corrects that omission by first studying the threat from Dunkirk to England's east coast and then addressing how the central government, counties, and coastal towns responded. A surprisingly rich vein of manuscript material from Great Yarmouth and particularly from the Suffolk fishing community of Aldeburgh informs this case study of the impact of this conflict around the North Sea.
Measurement of vortex shedding in the wake of a sphere at
Authors: Eshbal L. , Rinsky V. , David T. , Greenblatt D. , van Hout R. 
Published: May 2019

Flow in the wake of a sphere has been studied for at least the last hundred years. The three-dimensional (3-D) flow structure has been observed many times using dye visualization and prior to the direct numerical simulations by Johnson & Patel (J. Fluid Mech., vol. 378, 1999, pp. 19–70), its structure at a Reynolds number of approximately 300, was believed to consist of a one-sided chain of hairpin-like vortices. However, the numerical simulations by Johnson & Patel (J. Fluid Mech., vol. 378, 1999, pp. 19–70) also showed that so-called ‘induced’ vortices were generated. The present results are the first spatially resolved measurements that elucidate the 3-D vortex shedding cycle in the wake of a sphere at a Reynolds number of 465. Tomographic particle image velocimetry (tomo-PIV) enabled snapshots of the vortical structure and by combining these results with temporally resolved planar PIV, the ensemble averaged shedding cycle in the wake of the sphere was reconstructed. The present results clearly indicate that besides the ‘primary’ vortex chain shed from the sphere, secondary (‘induced’) vortices are generated by transforming transverse vorticity into streamwise vorticity as a result of the interaction between the sphere’s separating shear layer and the counter-rotating longitudinal vortices extending downstream from the sphere.
Political skill and organizational identification: Preventing role ambiguity from hindering organizational citizenship behaviour
Authors: De Clercq Dirk , Belausteguigoitia Imanol 
Published: May 2019

AbstractThis research investigates how employees' perceptions of role ambiguity might inhibit their propensity to engage in organizational citizenship behaviour (OCB), with a particular focus on the potential buffering roles of two personal resources in this process: political skill and organizational identification. Survey data collected from a manufacturing organization indicate that role ambiguity diminishes OCB, but this effect is attenuated when employees are equipped with political skill and have a strong sense of belonging to their organization. The buffering role of organizational identification also is particularly strong when employees have adequate political skills, suggesting the reinforcing, buffering roles of these two personal resources. Organizations that want to foster voluntary work behaviours, even if they cannot provide clear role descriptions for their employees, should nurture adequate personal resources within their employee ranks.
And now for something completely different: Reframing social processes of leadership theory using positive organisational behaviour
Authors: Muchiri Michael , Shahid Sehrish , Ayoko Oluremi 
Published: May 2019

AbstractProf. Ken Parry's (1998) conceptualisation of leadership as a social process provoked a shift in the understanding of the processes of influence in the context of achieving adaptation and change in response to changes in an organisation's environment. Reflecting on the state of leadership literature in recent years, we answer Ken's (2013) challenge to broaden our understanding of the positive outcomes achieved by social processes of leadership. Building on Ken's work, we propose a research framework that makes a linkage between the social processes of leadership, positive organisational behaviour, and specifically psychological capital.
Ancient canids of the Aleutian Islands (new archaeological discoveries from the Islands of Four Mountains)

Published: May 2019

AbstractWe discuss the cultural roles of dog and red fox recovered from Carlisle Island, Islands of Four Mountains, Alaska, within the context of Aleutian ethnographic and zooarchaeological records. Three dog bones were recovered from the Ulyagan archaeological site, Unit 5, in levels that date to AD 1450–1645. Three red fox bones come from the Ulyagan site, Unit 4, in levels that date 460 BC–AD 95. Our analyses show that both red fox and domestic dog date earlier than the contact with Russians and that these canids do not extend west of the Islands of Four Mountains archipelago. Given the rich history of human intervention on the Aleutians ecosystems over the last 250 years, we argue that indigenous red fox inhabited the Islands of the Four Mountains region prior to western contact; however, foxes did not have a pronounced cultural role for prehistoric Aleuts. Domestic dogs accompanied humans in the Aleutians after AD 950, suggesting that these canids might be linked with the Neo-Aleut culture. In the light of Arctic and oceanic cases of human use of dogs considered in the paper, we suggest that dogs might have served as reserve food sources during long trips for people migrating west.
Stratigraphic and Paleogeographic Significance of An Upper Ordovician Acritarch Flora from the Maquoketa Shale, Northeastern Missouri, U.S.A.
Authors: Wicander Reed , Playford Geoffrey , Robertson Eddie B. 
Published: May 2019

A well-preserved and moderately diverse acritarch assemblage was recovered from the upper Ordovician Maquoketa Shale of northeastern Missouri. Based on graptolite and conodont evidence, the Maquoketa in northeastern Missouri is considered Richmondian (=Ashgill) in age.The acritarch assemblage comprises 28 species, distributed among 17 genera including two new genera,CaelatosphaeraandStictosoma.There are 11 new species,Baltisphaeridium adiastaltum, Caelatosphaera verminosa(type species),Dorsennidium undosum, Elektoriskos aktinotos, Lophosphaeridium acinatum, L. varum, Micrhystridium hirticulum, M. prolixum, Peteinosphaeridium accinctulum, P. septuosum, andStictosoma gemmata(type species); together with two species similar to previously named species and three species left in open nomenclature. Cosmopolitan and stratigraphically important species identified includeBaltisphaeridium perclarumLoeblich and Tappan, 1978;Cheleutochroasp. cf.C. diaphorosaTurner, 1984;Dorsennidium hamii(Loeblich, 1970) Sarjeant and Stancliffe, 1994;Excultibrachium concinnumLoeblich and Tappan, 1978;Orthosphaeridium insculptumLoeblich, 1970;O. rectangulare(Eisenack, 1963) Eisenack, 1968, andVillosacapsula setosapellicula(Loeblich, 1970) Loeblich and Tappan, 1976.Polygonium gracileVavrdová, 1966 emend. Sarjeant and Stancliffe, 1994 andMicrhystridium hirticulumnew species dominate the assemblage, followed byDorsennidium undosumnew species,Baltisphaeridium oligopsakiumLoeblich and Tappan, 1978,Veryhachiumsp. cf.V. oklahomenseLoeblich, 1970,Peteinosphaeridium accinctulumnew species, andLophosphaeridium acinatumnew species. Additionally, the palynoflora contains chitinozoans, scolecodonts, cryptospores, and the enigmatic palynomorphGloeocapsomorpha priscaZalessky, 1917 emend. Foster, Reed, and Wicander, 1989.Paleontologic-palynologic and sedimentologic evidence indicates that the Maquoketa Shale at the two studied localities accumulated under low energy, somewhat offshore, and unrestricted marine conditions. The present Maquoketa Shale acritarch palynoflora shows greatest similarity to those of the Sylvan Shale (Ashgill; Richmondian) of Oklahoma and the Maquoketa Shale (Caradoc and Ashgill) of Kansas. Whereas there are some cosmopolitan acritarch species present in the Maquoketa Shale, its palynoflora shows no pronounced similarity with age-equivalent acritarch suites from outside of North America.
Analysis of parasite host-switching: limitations on the use of phylogenies
Authors: Jackson J. A. 
Published: May 2019

SUMMARYEven the most generalist parasites usually occur in only a subset of potential host species, a tendency which reflects overriding environmental constraints on their distributions in nature. The periodic shifting of these limitations represented by host-switches may have been an important process in the evolution of many host-parasite assemblages. To study such events, however, it must first be established where and when they have occurred. Past host-switches within a group of parasites are usually inferred from a comparison of the parasite phylogeny with that of the hosts. Congruence between the phylogenies is often attributed to a history of association by descent with cospeciation, and incongruence to host-switching or extinction in ‘duplicated’ parasite lineages (which diverged without a corresponding branching of the host tree). The inference of host-switching from incongrucnt patterns is discussed. Difficulties arise because incongruence can frequently be explained by different combinations of biologically distinct events whose relative probabilities are uncertain. Also, the models of host parasite relationships implicit in historical reconstructions may often not allow for plausible sources of incongruence other than host-switching or duplication/extinction, or for the possibility that colonization could, in some circumstances, be disguised by ‘false’ congruence.
COGNITIVE CORRUPTION AND DELIBERATIVE DEMOCRACY
Authors: Blau Adrian 
Published: May 2019

Abstract:This essay defends deliberative democracy by reviving a largely forgotten idea of corruption, which I call “cognitive corruption”—the distortion of judgment. I analyze different versions of this idea in the work of Machiavelli, Hobbes, Bentham, and Mill. Historical analysis also helps me rethink orthodox notions of corruption in two ways: I define corruption in terms of public duty rather than public office, and I argue that corruption can be both by and for political parties. In deliberative democracy, citizens can take off their party hats and may be more influenced by the force of the better argument than in party democracy.
CORRUPTION IN ADVERSARIAL SYSTEMS: THE CASE OF DEMOCRACY
Authors: Weinstock Daniel M. 
Published: May 2019

Abstract:In this essay I argue that adversarial institutional systems, such as multi-party democracy, present a distinctive risk of institutional corruption, one that is particularly difficult to counteract. Institutional corruption often results not from individual malfeasance, but from perverse incentives that make it the case that agents within an institutional framework have rival institutional interests that risk pitting individual advantage against the functioning of the institution in question. Sometimes, these perverse incentives are only contingently related to the central animating logic of an institution. In these cases, immunizing institutions from the risk of corruption is not a theoretically difficult exercise. In other cases, institutions generate perverse or rival incentives in virtue of some central feature of the institution’s design, one that is also responsible for some of the institution’s more positive traits. In multi-party democratic systems, partisanship risks giving rise to too close an identification of the partisan’s interest with that of the party, to the detriment of the democratic system as a whole. But partisanship is also necessary to the functioning of such a system. Creating bulwarks that allow the positive aspects of partisanship to manifest themselves, while offsetting the aspects of partisanship through which individual advantage of democratic agents is linked too closely to party success, is a central task for the theory and practice of the institutional design of democracy.
“DISMEMBERING THE HUMAN CHARACTER”: ADAM FERGUSON’S CONCEPTION OF CORRUPTION
Authors: Fleischacker Samuel 
Published: May 2019

Abstract:This essay lays out three kinds of corruption—personal, structural, and civic—stressing the differences among these phenomena. It then explores civic corruption via the work of the eighteenth-century Scottish thinker Adam Ferguson. Civic corruption occurs when the citizens of a republic lose interest in defending their shared institutions, and pursue their private wealth alone; avoiding it, according to Ferguson, requires placing limits on these private pursuits and getting citizens to participate in the public realm instead. By way of a comparison with Ferguson’s contemporary and friend Adam Smith—who agreed with Ferguson on many issues, although not on what was corrupting about the acquisition of wealth—the essay argues that Ferguson, for all his emphasis on participatory government, was a liberal, not a collectivist. With that in mind, the essay endorses many of Ferguson’s suggestions from a liberal perspective, and argues that, to preserve liberal republics, it is often necessary to expand what governments do, so as to maintain the commitment of citizens to their public institutions. This prescriptive implication brings out sharply how civic corruption differs from personal corruption, which may best be limited by shrinking the role of government, rather than expanding it.
THE CORRUPTION OF POLITICS
Authors: Philp Mark 
Published: May 2019

Abstract:This essay challenges conceptions of political corruption that rely on standards external to politics and explores an understanding of corruption as something that is part of the internal policing of politics. The essay draws attention to the multiple, conflicting ideas and principles that contribute to our understanding of corruption but argues that these often generate over-moralized and over-generalized claims and can become corrosive of the compromises and procedures that are central to political rule. The essay shows that recent accounts of political corruption often have highly attenuated understandings of “politics” and are over-expansive in their normative commitments, and argues that how we understand and talk about the corruption of politics is of major significance for the stability and effectiveness of the political orders of Western societies.
ON THE CONTINGENT VICE OF CORRUPTION
Authors: Munger Michael C. 
Published: May 2019

Abstract:This essay develops a notion of “functional corruption,” adapted from sociology, to note that the harm of corruption appears to be contingent. In a system of dysfunctional institutions, corruption can improve the efficiency and speed of allocative mechanisms of the bureaucracy, possibly quite substantially. The problem is that this “short run” benefit locks in the long run harm of corruption by making institutions much more difficult to reform. In particular, a nation with bad institutions but without bureaucracy may be much more open to reform than a nation with similarly bad institutions but with “efficiently corrupt” bureaucrats. The idea of a “long run” is developed using the North, Wallis, and Weingast conception of open access orders. Corrupt systems are likely to be locked into closed access orders indefinitely, even though everyone knows there are better institutions available.
THE CONTRIBUTION OF PSYCHOSOCIAL AND BIOGRAPHICAL VARIABLES TO HERITAGE LANGUAGE LEARNERS’ LINGUISTIC KNOWLEDGE OF SPANISH
Authors: Torres Julio , Estremera Ricardo , Mohamed Sherez 
Published: May 2019

AbstractIndividual differences (IDs) largely contribute to success in adult second language attainment (e.g., Dörnyei, 2006). Heritage language (HL) studies have also explored the role of IDs, namely psychosocial variables, and biographical factors with an adult HL learner population. However, the specific contribution of these variables to HL learners' performance on linguistic tests that differ in degree of explicitness and modality remains unknown. Therefore, the current study tested 103 adult HL learners of Spanish who completed a spoken elicited imitation task (EIT) and a written untimed grammaticality judgment task (UGJT) that elicited their knowledge of vulnerable morphosyntactic structures in HL bilingual acquisition. To investigate the contribution of individual learner factors on their performance, participants completed a few questionnaires. Mixed-effects regression models revealed that sequential bilingual status, willingness to communicate, generation and motivation contributed significantly, but yet differentially to participants' performance on grammatical and ungrammatical items of the EIT and UGJT.
