Redescription of Clubiona blesti Forster, 1979 (Araneae: Clubionidae) with a preliminary molecular phylogeny of New Zealand Clubiona
Authors: MALUMBRES-OLARTE JAGOBA , VINK COR J.
Published: March 2019

The New Zealand spider Clubiona blesti Forster, 1979 is redescribed, with the male described for the first time, and a pre-liminary molecular phylogenetic analysis of cytochrome c oxidase subunit I (COI) mtDNA sequences for eight species ofNew Zealand Clubiona and an outgroup from Tasmania is presented.There is considerable intraspecific variation in C. blesti, both genetic and in the morphology of copulatory organs,which may be explained by its wide distribution. The lack of a geographic structure based on consistent differences be-tween populations may suggest great dispersal ability. Given the limited sample size, further sampling and data on addi-tional genetic markers will be necessary to confirm this.The phylogenetic analysis of seven more species indicated that Clubiona cambridgei is the sister species of C. blestiand confirmed the existence of at least two monophyletic groups among the New Zealand Clubiona: species with a striped abdomen and with a spotted abdomen.
Systematics of the Etheostoma cinereum (Teleostei: Percidae) species complex (subgenus Allohistium)
Authors: POWERS STEVEN L. , KUHAJDA BERNARD R. , AHLBRAND SARAH E.
Published: March 2019

We examined geographic variation within the Ashy Darter, Etheostoma cinereum, of the mitochondrially enconded cyto-chrome b gene (cyt b) and nuclear recombination activation gene 1 (RAG1) as well as pigmentation, 6 meristic variables,and 20 morphometric variables for patterns indicative of speciation within the complex. Four geographically disjunct en-tities were identified by at least one of the datasets corresponding to the Cumberland, Duck, Elk, and upper Tennesseeriver systems. Monophyly of cyt b and RAG1 sequences, modal meristic differences, moderate morphometric divergence,and unique pigmentation in specimens from the Cumberland River suggest this entity represents an evolutionary speciesunder many different species concepts and is described herein as Etheostoma maydeni. Other populations exhibit varyingdegrees of divergence in the different datasets and have conflicting relationships in phylogenetic analyses using cyt b andRAG1 sequences, leaving the evolutionary history and taxonomic status of the Duck, Elk and upper Tennessee populations unclear.
Heterophleps inusitata, an extremely rare new moth species from western Yunnan, China (Lepidoptera, Geometridae, Larentiinae)
Authors: LI JING , JIANG NAN , HAN HONGXIANG
Published: March 2019

Heinitang is a small Lisu Nationality village located in western Yunnan Province, China, near the frontier of Myanmar. It is surrounded by low mountains covered with evergreen forests and shrubs (Fig. 1). As a tradition, the natives often cut and burn the forests for agriculture, resulting in increasing loss of forest habitat (Fig. 2). The moth fauna of this place is quite diverse, but as in other areas of the world, the biodiversity is decreasing due to more frequent human activities.

A review of the genera of Australian cicadas (Hemiptera: Cicadoidea)
Authors: MOULDS M. S.
Published: March 2019

The identities of all 242 described Australian Cicadoidea species (and their synonyms) have been confirmed, mostly byexamination of types, and their generic status reviewed. Male genitalia of all but two Australian species have beenexamined and those of the type species of each genus are figured. The first key to genera incorporating both males andfemales is presented along with a brief history of Australian genera. A cladistic analysis incorporating 71 species from thetribe Cicadettini is also presented, the primary purpose of which was to identify generic groupings and their apomorphies.The following 34 genera are described as new: Adelia gen. n., Auscala gen. n., Chelapsalta gen. n., Clinopsalta gen.n., Clinata gen. n., Dipsopsalta gen. n., Erempsalta gen. n., Ewartia gen. n., Galanga gen. n., Gelidea gen. n.,Heliopsalta gen. n., Limnopsalta gen. n., Mugadina gen. n., Myopsalta gen. n., Nanopsalta gen. n., Neopunia gen. n.,Noongara gen. n., Palapsalta gen. n., Paradina gen. n., Parnquila gen. n., Physeema gen. n., Pictila gen. n., Platypsaltagen. n., Plerapsalta gen. n., Punia gen. n., Pyropsalta gen. n., Simona gen. n., Sylphoides gen. n., Taurella gen. n.,Telmapsalta gen. n., Terepsalta gen. n., Toxala gen. n., Uradolichos gen. n., Yoyetta gen. n.Three genera, Cicadetta Kolenati, Notopsalta Dugdale, and Quintilia Stål, are removed from the fauna of Australia.Twelve species names are placed into junior synonymy and 74 new combinations are established. As a consequence ofthis review all 81 genera currently recognised as occurring in Australia are redefined using a common suite of charactersidentified as meaningful at generic level. To these have been added a further 35 characters when describing genera in the tribe Cicadettini in order to differentiate a large number of closely allied genera.
Redescription of Iluocoetes Jenyns, 1842; proposal of a new genus, Argentinolycus, for Iluocoetes elongatus (Smitt, 1898), and description of Patagolycus melastomus gen. et sp. nov. (Teleostei, Zoarcidae)
Authors: MATALLANAS JESÚS , CORBELLA CECÍLIA
Published: March 2019

The osteological characters of the two nominal species of Iluocoetes, I. fimbriatus and I. elongatus are quite different. Thepresent definition of Iluocoetes based on osteological characters is not valid since it was based on characters found in I. elong-atus but not in I. fimbriatus, the type species of the genus. In this paper, Iluocoetes is redefined on the basis of osteologicalcharacters found in the holotype of Iluocoetes fimbriatus and other specimens of the species, and Iluocoetes elongatus is placedin another genus: Argentinolycus gen. nov. Besides, a new genus and species, Patagolycus melastomus, is described on thebasis of fourteen specimens, 94−437 mm TL, collected from SW Atlantic Ocean, at depths of 164−489 m. The similaritiesfound between Patagolycus melastomus sp. nov. and Iluocoetes fimbriatus in body colour as well as in many meristic and mor-phometric characters, represent a remarkable example of how challenging zoarcid taxonomy can be. The differences betweenthese two species are highlighted. A tree showing interrelationships among the Magellanic endemic lycodine genera is included.

Poecilotherinae(Schmidt 1995) is no longer considered a valid subfamily and is replaced into Selenocosmiinae as the tribe Poecilotheriini.Chilocosmia barensteinerae Schmidt et al. 2010 is considered a Selenocosmiinae species incertae sedis. Ischnocolellasenffti Strand 1907 is considered a nomen dubium. All other genera examined were retrieved as monophyletic in the firstcladistic analyses exclusive to Selenocosmiinae genera (Australo-Papuan selenocosmiines are outside the scope of thiswork and are not considered). Biogeography of all Selenocosmiinae is discussed; the group is a potential model North Gondwanan taxon. A key to Psednocnemis species is provided.

A new genus of Lachesillidae (Psocoptera) from the Peruvian Amazonia
Authors: ALDRETE ALFONSO N. GARCÍA
Published: March 2019

Mockford & Sullivan (1986), proposed a higher classification of the psocopteran family Lachesillidae, in which they established the subfamilies Lachesillinae and Eolachesillinae. In the latter subfamily they created two tribes, Eolachesillini and Graphocaeciliini, and dealt with the systematics of the latter. In the Graphocaeciliini they recognised eight genera, including six new genera, and 29 species in total. Subsequently, García Aldrete (2006) erected the genus Waoraniella from the Ecuadorian Amazonia, and established for it the tribe Waoraniellini, in the Eolachesillinae; García Aldrete & Mockford (2011 b) described a second species of that genus, from the Reserva Florestal Ducke, near Manaus, Brazil, and indicated that a third species is known to occur in the Peruvian Amazonia, near Iquitos; finally, García Aldrete & Mockford (2011 a) described the genus Amazolachesilla, in the Graphocaeciliini, from the Brazilian state of Amazonas.

The family Sabellariidae is represented in Australian waters by eleven species belonging to five genera, including eight of themnew to Science: Idanthyrsus nesos n. sp., I. willora n. sp., Lygdamis wambiri n. sp., Phalacrostemma maloga n. sp., Sabellariakooraltha n. sp., S. lungalla n. sp., S. pyramis n. sp., and Tetreres terribilis n. sp. Three genera, Phalocrostemma, Sabellaria andTetreres, are newly recorded from Australia. Descriptions of all species are given, acompanied by detailed illustrations, includingdrawings, photographs and scanning electron micrographs, tables summarising specific diagnostic characters of all species ofeach genus, and distribution maps within Australia. A key to all genera worldwide and Australian species is given. Maximumparsimony analyses based on morphological features have been performed to assess the position of the new species and relation-ships with other Sabellariidae. For this purpose, the Australian species, the type species of each genus and some others species,representing the variability within each group, were incorporated into the analyses. Some of the species were recovered withinmonophyletic genera (Phalacrostemma and Tetreres), while others have been considered as member of previously recognised genera (Idanthyrsus, Lygdamis and Sabellaria) have not been assessed as monophyletic.

Species of adeliine braconids were previously described and named from all biogeographic areas of the world except the Neotropical Region. Here we present the first taxonomic revision of New World adeliines, as well as the first newly described species of both genera, Adelius and Paradelius, from the Neotropical Region. Although not commonly sampled because of their minute size and associations with leaf-mining hosts, our results indicate that adeliines actually have a wide distribution in the neotropics, especially in middle to high elevations and dry forests. In addition to redescriptions of all known Nearctic species, we present the first descriptions of the females of Adelius coloradensis and A. nigripectus, of 16 new species of the genus Adelius (A. adeleae Shimbori & Shaw sp. n., A. bolivariensis Bortoni & Penteado-Dias sp. n., A. boliviensis Bortoni & Penteado-Dias sp. n., A. caatinga Bortoni, Shimbori & Penteado-Dias sp. n., A. canadensis Shimbori & Shaw sp. n., A. ecuadoriensis Bortoni & Penteado-Dias sp. n., A. excelsus Bortoni & Shimbori sp. n., A. floridensis Shimbori & Shaw sp. n., A. gauldi Shimbori & Shaw sp. n., A. janzeni Shimbori & Shaw sp. n., A. monteiroi Souza-Gessner, Cerântola & Penteado-Dias sp. n., A. morretesiensis Bortoni, Shimbori & Penteado-Dias sp. n., A. panamensis Shimbori & Shaw sp. n., A. pentagonalis Shimbori & Shaw sp. n., A. quiteriae Souza-Gessner, Cerântola & Penteado-Dias sp. n., and A. sancticaroli Bortoni, Penteado-Dias & Shimbori sp. n.), and one new species of the genus Paradelius (P. neotropicalis Shimbori & Shaw sp. n.).

In a recently published article (Saglam et al. 2018) the name of a new species of Hirudinea (Annelida, Clitellata) was simultaneously published in three different ways, as Helobdella serendipitious (Saglam et al. 2018: 61, 70, 71, 73), Helobdella serendipitous (ibid.: 63, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74), and as Helobdella serendipidous (ibid.: 75). Acting as first reviser according to Article 24 of the International Code of Zoological Nomenclature (ICZN 1999) here we determine serendipitous as the correct spelling of the species epitheton.
Might Dendrelaphis caudolineatus (Gray, 1834) (Squamata: Colubridae) present in India?

Published: March 2019

The colubrid snake genus Dendrelaphis comprises of 45 species (Uetz et al. 2018) of which eleven currently occurs in India (Aengals et al. 2018). A member of this genus, Dendrelaphis caudolineatus (Gray, 1834), was once considered a wide-ranging species in Southeast Asia, the Philippines and the Indo-Australian Archipelago, until Van Rooijen & Vogel (2012) resolved taxonomy of this species complex. Now its range is restricted from southern Thailand to Sundaland (Peninsular Malaysia, Sumatra, Billiton and Borneo; presence doubtful in Java of Indonesia) (Van Rooijen & Vogel 2012).
Strong Wind Speed Events over Antarctica and Its Surrounding Oceans
Authors: Yu Lejiang , Zhong Shiyuan
Published: March 2019

Strong wind events (SWEs) over Antarctica and its surrounding oceans are investigated using gridded surface wind data from the ERA-Interim for the 1979–2017 period. Throughout the year, SWEs are more prevalent over the coastal region of East Antarctica where mean surface wind speeds are also higher. The occurrences of SWEs appear to be accompanied by positive anomalies in surface temperature and negative (positive) anomalies in mean sea level pressure related to cyclone (anticyclone) activity over the Ronne and Ross Ice Shelves and coastal regions (the inland areas of East Antarctica). The interannual variability of the SWE occurrences appears to be related to the southern annular mode (SAM) and, to a lesser degree, ENSO. The trends of SWE in the recent four decades exhibit considerable regional variations that are consistent with the trends in seasonal mean wind speed and surface air temperature, and can be largely explained by the variations in the sea level pressure trends across the region.
Adolescent feedback on predisposing, reinforcing and enabling features in asthma self-management apps
Authors: Roberts Courtney A , Sage Adam J , Geryk Lorie L , Sleath Betsy L , Carpenter Delesha M
Published: March 2019

Objective:

Mobile health apps hold potential to support and reinforce positive health behaviours, especially among young people with chronic diseases like asthma that require continual self-management. We aimed to gain feedback from adolescents with asthma on two existing asthma self-management apps to guide the development of an evidence- and theory-based asthma app that meets their asthma management needs.

Design:

A qualitative interview study was conducted with adolescents with persistent asthma ( n = 20), aged 12–16.

Setting:

Interviews took place after the individual’s clinic appointment and during telephone interviews one week later.

Methods:

Participants provided feedback on two asthma self-management apps during two semi-structured interviews. Interviews were audio-recorded, transcribed verbatim and analysed thematically using MAXQDA 11. The Precede–Proceed Model (PPM) was used as a framework to evaluate perceptions of app features, including utility. Suggestions for improvements, including addition of predisposing, reinforcing and enabling PPM features, were identified.

Results:

The majority of app features functioned as enabling (e.g. inputting triggers, recording doctor’s appointments and tracking peak flow). However, participants recommended addition of predisposing and reinforcing features, including knowledge on dealing with asthma triggers (predisposing) and a reward system for daily peak flow entry (reinforcing), to support their asthma management.

Conclusion:

Findings suggest that including predisposing, reinforcing and enabling features in asthma apps could facilitate asthma self-management. Public health professionals should partner with app developers in the development of asthma self-management apps that include predisposing, reinforcing and enabling features to meet user needs and ensure they are effective and accepted behaviour change apps.
Beyond Fitts’s Law: A Three-Phase Model Predicts Movement Time to Position an Object in an Immersive 3D Virtual Environment
Authors: Deng Cheng-Long , Geng Peng , Hu Yi-Fei , Kuai Shu-Guang
Published: March 2019

Objective:

The study examines the factors determining the movement time (MT) of positioning an object in an immersive 3D virtual environment.

Background:

Positioning an object into a prescribed area is a fundamental operation in a 3D space. Although Fitts’s law models the pointing task very well, it does not apply to a positioning task in an immersive 3D virtual environment since it does not consider the effect of object size in the positioning task.

Method:

Participants were asked to position a ball-shaped object into a spherical area in a virtual space using a handheld or head-tracking controller in the ray-casting technique. We varied object size (OS), movement amplitude (A), and target tolerance (TT). MT was recorded and analyzed in three phases: acceleration, deceleration, and correction.

Results:

In the acceleration phase, MT was inversely related to object size and positively proportional to movement amplitude. In the deceleration phase, MT was primarily determined by movement amplitude. In the correction phase, MT was affected by all three factors. We observed similar results whether participants used a handheld controller or head-tracking controller. We thus propose a three-phase model with different formulae at each phase. This model fit participants’ performance very well.

Conclusion:

A three-phase model can successfully predict MT in the positioning task in an immersive 3D virtual environment in the acceleration, deceleration, and correction phases, separately.

Application:

Our model provides a quantitative framework for researchers and designers to design and evaluate 3D interfaces for the positioning task in a virtual space.
Position taking and field level change: Capability Brown and the changing British landscape
Authors: Wild Andrew , Lockett Andy , Currie Graeme
Published: March 2019

How does a social actor in a disadvantaged position achieve field level change? Using a longitudinal case of ‘Capability’ Brown, an individual rising from humble origins to shape and refine the British landscape, we examine how an actor’s unfolding efforts to move from a social position at the periphery of a field, to a social position at the centre of a field, may present them with opportunities to influence field level change. In doing so, we employ Bourdieu’s Theory of Practice, and unexplored notion of ‘position taking’. We argue that an actor’s tactics to shape change, and position taking to enhance social position, should be considered in conjunction with one-another, and that position taking strategies may be viewed as a core component of the work undertaken by social actors in trying to influence field level change. Further, we suggest that tensions between an agent’s accumulated capital and the social position typically afforded to their role in the field, may lead to efforts to ‘take’ or ‘create’ new positions, providing opportunities to influence the developing institution, with symbolic capital playing a pivotal role.

To investigate the application of inner ear 3-dimensional fluid-attenuated inversion recovery (3D-FLAIR) magnetic resonance imaging (MRI) in patients with sudden sensorineural hearing loss (SSNHL) accompanied by inner ear hemorrhage. A total of 1252 SSNHL patients who were admitted from January 2010 to April 2018 were included in the study. The patients’ clinical features, complete blood counts, coagulation profiles, audiometry data, and MRI scans were retrospectively reviewed. Twenty-four patients had high labyrinth signals on inner ear 3D-FLAIR MRI (24/1252, 1.9%) that were diagnosed as inner ear hemorrhage. One patient had endolymphatic hydrops on the contralesional side. In the 24 patients, pure tone audiometry curves revealed profound deafness (19/24) and flat moderate hearing loss (5/24); most patients had associated vertigo (23/24) and tinnitus (19/24). Patients with SSNHL (N = 24) were treated. Sixteen patients had invalid improvement, 3 patients were markedly improved, 4 patients had effective treatment, and only 1 patient was cured, for a therapeutic efficacy of 33.3% (8/24). Follow-up 3D-FLAIR MRI in patients showed absorbance of labyrinthine hemorrhage and disappearance of the high signal intensity in the inner ear within 2 weeks to 4 months. Inner ear 3D-FLAIR MRI indicate that most cases of inner ear hemorrhage are spontaneous and that high labyrinth signals are absorbed within 4 months. The site of labyrinth hemorrhage is irregular and independent of hearing loss. Conventional treatment is not very effective, and an appropriate therapy for SSNHL requires further investigation.

Authors: Brown C. Scott , Peskoe Sarah B. , Risoli Thomas , Garrison Douglas B. , Kaylie David M.
Published: March 2019

Objective

To determine relationships between caloric testing (CT) and video head impulse testing (vHIT) among patients with unilateral vestibular schwannoma (VS). To describe the distribution of CT and vHIT measurements and assess associations with tumor size and self‐perceived handicapping effects.

Study Design

Retrospective review.

Setting

Tertiary referral hospital.

Subjects and Methods

Subjects were adults with presumed unilateral VS between 2014 and 2017. Interventions were CT and vHIT. Primary outcomes were vHIT value (abnormal <0.8) and CT value (abnormal >25%). Secondary outcomes were tumor size and Dizziness Handicap Inventory scores.

Results

Fifty‐one individuals had complete data for CT and vHIT. The odds of abnormal gain increases by 2.18 for every 10% increase in unilateral weakness on CT (range, 1.44‐3.34; P <. 001). A significant negative correlation between CT and gain exists (rs = −0.64, P <. 001). Odds of observing saccades increased by 2.68 for every 10% increase in unilateral weakness (range, 1.48‐4.85; P =. 001). This association was larger in magnitude for overt than covert saccades (odds ratios, 2.48 and 1.59, respectively). Tumor size was significantly associated with an increase in caloric weakness (β = 0.135, P <. 001). With every 10‐mm increase of tumor size, odds of abnormal gain on vHIT increased 4.13 (range, 1.46‐11.66; P =. 007). Mean Dizziness Handicap Inventory score was 19.7 (σ = 22), without association to caloric weakness, gain, or tumor size.

Conclusion

CT and vHIT both effectively assess vestibular function for patients with VS and correlate to tumor size. These findings are important as vHIT has a lower overall cost, improved patient tolerance, and demonstrated reliability.

Published: March 2019

Objective

To determine the contribution of the nasal floor and hard palate morphology to nasal obstruction for nonresponders to prior intranasal surgery.

Study Design

Retrospective case‐control study.

Setting

Tertiary academic center.

Methods

Institutional review board–approved, retrospective institutional database analysis was obtained of a cohort of 575 patients who presented with nasal obstruction over a 21‐year period. Of the patients, 89 met inclusion criteria: 52 were placed into the experimental group, defined as having persistent nasal obstruction following endoscopic sinus surgery (ESS), septoplasty, nasal valve repair, and/or turbinoplasty using validated subjective questionnaires, and 37 were placed into the control group, defined as having resolution of subjective nasal obstruction. Computed tomography imaging was presented to 3 blinded experts, who measured numerous nasal airway and hard palate morphology parameters, including anterior nasal floor width, anterior maxillary angle, maxilla width, anterior nasal floor width, and palatal vault height. Standard demographic information, comorbidities, perioperative 22‐item Sinonasal Outcome Test (SNOT‐22), and follow‐up time were also assessed. Wilcox rank sum analysis or t test was performed where appropriate.

Results

Follow‐up ranged from 2 to 36 months following surgical intervention. Several skeletal characteristics within the upper airway were significantly associated with persistent nasal obstruction, including acute maxillary angle (P =. 035), narrow maxillary width (P =. 006), and high arched palate (P =. 004).

Conclusion

Persistent nasal obstruction may be seen in patients with narrow, high arched hard palate despite prior nasal surgical intervention and may benefit from additional skeletal remodeling procedures such as maxillary expansion.
Endoscopic Type 1 Tympanoplasty in Chronic Otitis Media: Comparative Study with a Postauricular Microscopic Approach
Authors: Ohki Masafumi , Kikuchi Shigeru , Tanaka Sunao
Published: March 2019

Objective

To compare surgical outcomes after tympanoplasty without ossiculoplasty for chronic otitis media between transcanal endoscopic ear surgery (TEES) and postauricular microscopic ear surgery (PAMES).

Study Design

Case‐control study.

Setting

Tertiary care university hospital.

Subjects and Methods

Consecutive patients (N = 122) who had undergone tympanoplasty without ossiculoplasty for chronic otitis media were enrolled in this retrospective study and divided into 2 groups: TEES (n = 47) and PAMES (n = 75). Middle ear condition was graded with the middle ear risk index. Hearing, repair of tympanic membrane perforation, and surgical time were assessed.

Results

The surgical success rate for hearing (air‐bone gap ≤20 dB) was 95.7% in the TEES group and 84.0% in the PAMES group. Lower middle ear risk resulted in similar mean (95% CI) closure of air‐bone gaps (TEES: 9.6, 6.5‐12.6; PAMES: 8.0, 6.4‐9.7; P =. 333), whereas higher middle ear risk demonstrated significantly larger closure of air‐bone gaps for the TEES group (10.1, 3.3‐16.9) than the PAMES group (–0.2, –4.5 to 4.2; P =. 009). The surgical success rate for repair of tympanic membrane perforation and surgical time were equivalent between TEES and PAMES.

Conclusion

Under favorable conditions of the middle ear, TEES and PAMES resulted in similar hearing improvement by tympanoplasty without ossiculoplasty. However, under adverse conditions of the middle ear, TEES was a more beneficial approach for hearing improvement than PAMES.

Published: March 2019

We investigated the effect of real-time technology-enhanced performance-based feedback delivered during three different routines on teacher practice and child outcomes. Participants were three early childhood special education teachers and three focus preschool children identified with autism spectrum disorder. We used a multiple-probe single-case design to provide real-time technology-enhanced performance-based feedback across child-led, teacher-led, and mealtime routines. We collected generalization data across a fourth novel routine, clean-up. We analyzed teachers’ use of communicative antecedents and consequences, children’s responses to antecedents, and children’s expressive communication. Real-time technology-enhanced performance-based feedback enhanced teachers’ use of communicative antecedents and consequences, and when teachers used antecedents, children responded to these opportunities and practiced their expressive communication.
Transportation Safety Planning Approach for Pedestrians: An Integrated Framework of Modeling Walking Duration and Pedestrian Fatalities
Authors: Lee Jaeyoung , Abdel-Aty Mohamed , Huang Helai , Cai Qing
Published: March 2019

Multiple approaches have been proposed to take traffic safety into consideration in long-term transportation plans, referred to as transportation safety planning. Some early studies used trip generation data as the explanatory variables for their macro-level crash safety performance functions, or crash prediction models. However, no study to date has attempted to integrate walking exposure and pedestrian safety at the modeling stage. Thus, a novel methodological framework for integrating the analyses of walking exposure and pedestrian crashes is proposed toward better transportation safety planning for pedestrians. In comparison with walking trips and walking miles, walking hours was identified as the best walking exposure variable by a preliminary analysis. Thus, an integrated modeling structure with walking hours as its exposure variable was developed. The modeling results indicate that climate conditions, population, and car usage patterns affect walking hours, and predicted walking hours, climate conditions, percentage of mid-elderly (64–75 years), proportions of minority race/ethnicity, and percent of tertiary industry occupations have significant effects on pedestrian fatalities. In addition, the integrated modeling framework was compared with non-integrated ones, and the results indicate that the integrated framework outperforms its counterparts in relation to deviance information criterion. The proposed approach and the findings from this study are expected to provide useful insights not only to researchers but also to policy makers and practitioners in the fields of transportation planning and traffic safety.
Mess is more: Radical democracy and self-realisation in late-modern societies
Authors: Ebert Norbert
Published: March 2019

The following discussion highlights the sociological relevance of Maria Márkus’s work for the Budapest School’s concept of ‘radical democracy’. A brief historical sketch exhibits how the concept has emerged. It is in particular the ‘messy’ social conditions for equal and free forms of self-realisation in civil society that underpin radical democracy which are central in Maria Márkus’s critique of the neoliberal state, identity formation and a gendered achievement principle. Her approach, I argue, can be advanced as a prism for the critical analysis of contemporary issues. To do so, I contend that late-modern societies are increasingly defined by a paradox with a pluralisation of identity claims in civil society on the one hand, and tendencies to homogenise identities on the other by concurring economic and political forces. A democratisation of everyday life, and with it diverse and plural forms of self-realisation, appears to be under homogenising pressures from governments and markets alike. This will be briefly demonstrated using Maria Márkus’s work, which also points toward possible departure points to advance a critical sociology of radical democracy.
Perampanel Pharmacokinetics in Children: Correlation of Dose With Serum Concentrations
Authors: Gaudio Elizabeth , Gienapp Andrew J. , Wheless James
Published: March 2019

Enzyme-inducing antiseizure drugs taken concomitantly with perampanel are known to influence perampanel serum concentrations. In this study, we examined perampanel dosage, serum concentrations, and the effect of concomitant enzyme-inducing antiseizure drugs in children for a 3-year period. A retrospective chart review determined patient age, weight, perampanel serum concentration and prescribed dose, and concomitant drugs. Of 87 patients included in the study, 41 were prescribed an enzyme-inducing antiseizure drug. Although perampanel dosage did not differ between patients prescribed/not prescribed enzyme-inducing antiseizure drugs, serum concentrations were significantly lower in patients taking enzyme-inducing antiseizure drugs (average serum concentration for the enzyme-inducing antiseizure drug group was still above the previously reported efficacious serum concentration of 70 ng/mL). Although perampanel serum concentrations are negatively influenced by enzyme-inducing antiseizure drugs in children, it is likely that efficacy would be improved in patients not concomitantly prescribed enzyme-inducing antiseizure drugs because pediatric perampanel dosing is similar to that reported in prior adult efficacy trials.
Measuring Participation in Employer-Sponsored Health and Well-Being Programs: A Participation Index and Its Association With Health Risk Change
Authors: Seaverson Erin L. D. , Gingerich Stefan B. , Mangen David J. , Anderson David R.
Published: March 2019

Purpose:

To develop an index of participation in workplace health and well-being programs and assess its relationship with health risk status.

Design:

Study design comprised a retrospective longitudinal analysis of employee health risk assessment (HRA) and program participation data.

Setting:

Data from 6 companies that implemented health and well-being programs from 2014 to 2016.

Participants:

Employee participants (n = 95 318) from 6 companies who completed an HRA in 2014 to 2016. After matching those who completed the HRA in all 3 years, the longitudinal file included 38 789 respondents.

Measures:

Participation indicators were created for 9 different program components. The sum of these 9 components established the total participation index.

Analysis:

Descriptive and correlation analyses were conducted on all participation measures. Repeated-measures analysis of variance was used to assess the impact of participation level on health risk over time.

Results:

Higher levels of participation were associated with a greater reduction in risks, with each participation dose yielding a reduction of 0.038 risks ( P < .001).

Conclusion:

Results suggest that employees who participate more in workplace health and well-being programs experience more health risk improvement. The study also supports a more granular definition of participation based on the number of interactions and type of program.
Effect of circumferential static pressure nonuniformity caused by volute on tip leakage flow in a centrifugal compressor
Authors: Fu Li , Yang Ce , Bao Wenrui , Zhang Hanzhi , Yang Changmao , Li Yanzhao
Published: March 2019

For a centrifugal compressor with volute, the flow field is circumferentially nonuniform because of the volute asymmetrical structure and leads to a circumferential difference in the tip leakage flow. In this work, the compressor performance and the casing wall static pressure distribution are measured, and the results are compared with the time-averaged results of the unsteady calculation to verify the reliability of the simulation. The results show a relationship between the tip leakage vortex trajectory and the high static pressure region in the diffuser, based on which a prediction model is established for the reverse propagation of pressure waves caused by a volute tongue. Influenced by the volute asymmetric structure, the trajectory, shape, and strength of the tip leakage vortex at different circumferential positions differs significantly. The tip leakage vortex trajectory affected by the high static pressure is more inclined to a circumferential direction because the tip leakage flow velocity flowing out of the suction surface is reduced, and the tip leakage flow with low velocity is subjected to the high-pressure gradient in a passage. Moreover, the tip leakage vortex breakdown in different passages differs significantly. A tip leakage vortex core more inclined towards the streamwise direction is more likely to break down than a tip leakage vortex core inclined towards the circumferential direction because of the larger reverse pressure gradient.
Analysis on vibration control of a large-span pedestrian suspension bridge based on a multiple tuned mass damper system
Authors: Li Zhen , Li Dejian , Lu Yao , Tang Chao
Published: March 2019

Tuned mass damper is one of the commonly used passive control devices. It is the earliest used device in civil engineering control of vibration control of high-rise buildings and towering structures. For large-span pedestrian bridges, the pedestrian load spectrum covers many modalities of pedestrian bridges. It is difficult to achieve the expected results with a single tuned mass damper device. In order to obtain efficient damping, the multiple modes of a multiple tuned mass damper which may resonate under excitation are controlled. This chapter adopts the pedestrian suspension bridge over Dongtan River as the subject to arrange a multiple tuned mass damper system in the finite element model of the pedestrian suspension bridge, analyze the effectiveness of the multiple tuned mass damper system on the control of human-induced vibration of a large-span pedestrian suspension bridge, and discuss the vibration reduction effect of the multiple tuned mass damper system on the response to human-induced vibration of the pedestrian suspension bridge. The analysis shows that a multiple tuned mass damper system has a significant effect on controlling human-induced vibration of the pedestrian suspension bridge.
