Contributions to the taxonomy of the Normanellidae (Copepoda, Harpacticoida): description of a new genus from the Brazilian continental shelf and re-assignment of Pseudocletodes vararensis Scott & Scott, 1893 (ex Nannopodidae)
Authors: KIHARA TERUE CRISTINA , HUYS RONY
Published: July 2019

A new genus and species of Normanellidae (Copepoda, Harpacticoida), Paranaiara inajae gen. et sp. nov., is described from the continental shelf off the northern coast of São Paulo State, Brazil. The new genus differs from the type genus Normanella Brady, 1880 and Sagamiella Lee & Huys, 1999 in its presence of lamelliform caudal rami, a maxillulary endopod represented by 2 setae, an unarmed maxillipedal syncoxa, and reduced setation on P2 enp-2 (without outer spine) and P3 enp-2 (with only 2 inner setae). All these apomorphic character states are shared with the genus Pseudocletodes Scott & Scott, 1893, formerly placed in the family Nannopodidae (ex Huntemanniidae) and here assigned to the Normanellidae. Pseudocletodes can be differentiated from Paranaiara by the loss of the P1 endopod and of the inner seta on P2–P4 enp-1, the presence of only 2 inner setae on P2 enp-2 (instead of 3) and only 1 inner seta on P4 exp-3 (instead of 2), the presence of a second inner seta on P4 enp-2 (instead of 1), the morphology of the fifth pair of legs which are not medially fused and have only 3 endopodal elements (instead of 4) in the male, and the well developed caudal ramus seta V (instead of rudimentary). It is postulated that prehensility of the P1 endopod was secondarily lost in the common ancestor of Paranaiara and Pseudocletodes. An updated family diagnosis of the Normanellidae and a dichotomous identification key to the 22 currently valid species are presented.
A new subspecies of Batagur affinis (Cantor, 1847), one of the worlds most critically endangered chelonians (Testudines: Geoemydidae)

Published: July 2019

Estuarine Batagur are among the most critically endangered chelonian species. We assess the taxonomic status of the recently discovered Cambodian relic population of Batagur by phylogenetic analyses of three mitochondrial (2096 bp) and three nuclear DNA fragments (1909 bp) using sequences from all other Batagur species and selected allied geoemydids. Furthermore, we calculated haplotype networks of the mitochondrial cytochrome b gene for Cambodian terrapins, B. affinis, B. baska, and B. kachuga and compare external morphology of estuarine Batagur populations. Genetically, Cambodian Batagur are closely related with, but distinct from B. affinis from Sumatra and the west coast of the Malay Peninsula. Morphologically, Cambodian Batagur resemble the distinctive B. affinis populations from the eastern Malay Peninsula that were not available for genetic study. We suggest that the Batagur populations from the eastern Malay Peninsula and Cambodia represent a new subspecies of B. affinis that once was distributed in estuaries surrounding the Gulf of Thailand (Batagur affinis edwardmolli subsp. nov.). Its patchy extant distribution is most probably the result of large-scale habitat alteration and century-long overexploitation. In addition, our phylogenetic analyses suggest repeated switches between riverine and estuarine habitats during the evolution of the extant Batagur species.
The deep-sea Anguilliformes and Saccopharyngiformes (Teleostei: Elopomorpha) collected on the Brazilian continental slope, between 11o and 23o S

Published: July 2019

A review of the deep-sea anguilliform and saccopharyngiform eels collected by the French R/Vs Marion Dufresne (1987), Thalassa (1999, 2000), and the Brazilian Astro Garoupa (2003) revealed a great diversity of these groups on the Brazilian continental slope (11–23 o S, 19–40 o W), in the depth range of 233 to 3450 m. Of the 33 species collected, 13 (39.4%) are being reported for the first time in the western South Atlantic. New taxa are represented by one species recently described and few other are probably undescribed. The most species-rich family in the area was Synaphobranchidae (11 species), followed by Congridae (9), Nettastomatidae (5), Nemichthyidae (3), Serrivomeridae (2), Colocongridae (1), Cyematidae (1), and Eurypharyngidae (1). Regarding the vertical species distribution, a gradual transition of species was observed, without any clear break along the slope.
A New Species of the Freshwater Cladoceran Genus Scapholeberis Schoedler, 1858 (Cladocera: Anomopoda) from the Semidesert Northern Mexico, Highlighted by DNA Barcoding
Authors: QUIROZ-VÁZQUEZ PATRICIA , ELÍAS-GUTIÉRREZ MANUEL
Published: July 2019

Sequencing of the CO1 mitochondrial gene (barcoding) highlighted a possible different species in the semi-desert region of Mexico. After a detailed morphological analysis we describe Scapholeberis duranguensis n. sp. (Cladocera: Anomopoda: Daphniidae). Specimens from the type locality, El Chupadero, Durango, were compared with specimens of S. armata armata Herrick, 1882 and S. armata freyi Dumont and Pensaert, 1983 from Canada and southeastern, central and northern Mexico. The main characters that differentiate the new species are: (1) a thicker denticulate membrane with a conspicuous underlying hyaline membrane at the posterior rim of the valves, (2) fewer setae in the gnathobase of trunk limb II and (3) longer and more rectilinear ejector hooks in trunk limb I. The presence of a pore-like structure at the top of the head was also observed, however we are not certain whether this can be considered as a distinctive character, as it was not consistent in all SEM scanned organisms. The denticulate membrane, the number of setae in the gnathobase of trunk limb II and the length of the ejector hooks are characters shared with other species, however, the combination of them and in particular the structure and thickness of the double membrane at the posterior rim of the valves lead us to conclude that S. duranguensis is a species different from S. armata and from other members of this genus. The CO1 sequences of S. armata freyi and S. duranguensis n. sp. showed a mean divergence of 12.02%, thus supporting the morphological differences between them. Finally, a comparison of the CO1 sequences of Scapholeberis duranguensis n.sp. with other Scapholeberinae available in GenBank supported our results.
Phylogenetic analysis of nematode nuclear 18S rDNA sequences indicates the genus Tripylina Brzeski, 1963 (Nematoda: Tripylidae de Man, 1876) should be placed in Enoplida
Authors: ZHAO ZENG QI , BUCKLEY THOMAS R.
Published: July 2019

We have made an extensive study of New Zealand representatives of nematodes from the family Tripylidae de Man, 1876. Based on SSU DNA sequence data and phylogenetic analysis, the genera Tripylina Brzeski, 1964 and Trischistoma Cobb, 1913 are not closely related to Tripyla Bastian, 1865, the type genus of the family Tripylidae de Man 1876. The genus Tripylina is sister to Trischistoma and Trefusia de Man, 1893 and is more closely related to Enoplida than to Triplonchida. Our phylogenetic results indicate that Tripylina should be placed in Enoplida.
Gnathia nubila n. sp. and a new record of Gnathia grandilaris (Crustacea, Isopoda, Gnathiidae) that parasitizes elasmobranchs from Okinawan coastal waters, Japan
Authors: OTA YUZO , HIROSE EUICHI
Published: July 2019

Gnathiid larvae were collected as ectoparasites on elasmobranchs caught in fisheries off Okinawa Island, Ryukyu Archipelago, southwestern Japan. The larvae were reared in a laboratory aquarium; some metamorphosed into male and female adults of Gnathia nubila n. sp. and Gnathia grandilaris Coetzee, Smit, Grutter & Davies, 2008. Males of G. nubila n. sp. were easily distinguished from all other species by the bifit and dentate mediofrontal process of the frontal border and by a narrow pleotelson. Gnathia grandilaris was originally recorded from the Great Barrier Reef (GBR), Australia, and here we report a second find of this species from the Ryukyus. Since the first description did not include female adult of G. grandilaris, we provide the morphology of female.
Revision of the Australian Oenochroma vinaria Guenée, 1858 species-complex (Lepidoptera: Geometridae, Oenochrominae): DNA barcoding reveals cryptic diversity and assesses status of type specimen without dissection
Authors: HAUSMANN AXEL , HEBERT PAUL D. N. , MITCHELL ANDREW , ROUGERIE RODOLPHE , SOMMERER MANFRED , EDWARDS TED , YOUNG CATHERINE J.
Published: July 2019

The assembly of a DNA barcode library for Australian Lepidoptera revealed that Oenochroma vinaria Guenée, 1858, as currently understood, is actually a mix of two different species. By analyzing DNA barcodes from recently collected specimens and the 150 year-old female lectotype of O. vinaria, we propose a reliable assignment of the name vinaria to one of these two species. A lectotype is designated for Monoctenia decora, a confirmed synonym of O. vinaria, and a new species, Oenochroma barcodificata sp. nov., is described. This species is only known from Tasmania and New South Wales; its biology and immature stages are described in detail.
Biting midges of the genus Atrichopogon Kieffer (Diptera: Ceratopogonidae) described by Kieffer from Taiwan
Authors: SZADZIEWSKI RYSZARD , DOMINIAK PATRYCJA
Published: July 2019

Twelve species of biting midges of the genus Atrichopogon reported by Kieffer (1912, 1916a,b, 1921, 1922) from Taiwan are redescribed, illustrated and/or interpreted. They are included in the subgenus Psilokempia Enderlein (A. myrmedon Kieffer, 1912) and in the subgenus Atrichopogon s. str. (A. argus Kieffer, 1916, A. flaviceps Kieffer, 1912, A. haemorrhoidalis Kieffer, 1921, A. insularis Kieffer, 1921, A. minimus Kieffer, 1916, A. pruinosus Kieffer, 1921 and A. ruber Kieffer, 1916). Five new synonyms are proposed for the following species: A. ruber Kieffer, 1916 (=A. formosanus Kieffer 1918), A. myrmedon Kieffer, 1922 (=A. quadrispinosus Remm, 1993; =A. pectinacaudalis Yu & Yan, 2006), A. insularis Kieffer, 1921 (=A. citrinipes Kieffer, 1922) and A. flaviceps Kieffer, 1912 (=A. mendax Kieffer, 1922, as var. of A. flaviceps). Atrichopogon crispantis Liu, Yan & Liu, 1996 is resurrected from synonymy with A. insularis Kieffer, 1921. Atrichopogon rufescens Kieffer, 1921 is recognized as a nomen dubium, while A. atriceps mentioned by Blech & Rohlfien (1987) is considered a nomen nudum. A key to the species described by Kieffer from Taiwan is provided.
A new species of Leptobasis from Costa Rica (Odonata: Coenagrionidae)
Authors: PAULSON DENNIS R.
Published: July 2019

Leptobasis guanacaste is described from seasonal wetlands in dry forest in Guanacaste, Costa Rica. It is unique among the five species of the genus in thoracic color pattern and the structure of the male terminal appendages and female mesostigmal laminae and appears to be closest to L. candelaria through similarities in genital ligula, male metafemur, and female ovipositor.
Anystipalpus, Antennoseius and Vitzthumia: a taxonomic and nomenclatural conundrum of genera (Acari: Mesostigmata: Dermanyssina), with description of four species of Anystipalpus
Authors: LINDQUIST EVERT E. , MORAZA MARÍA L.
Published: July 2019

The genus Anystipalpus Berlese, 1911, of uncertain prior placement in the superfamilies Ascoidea or Dermanyssoidea, is redescribed, based on reexamination of type and other material of the type-species, A. percicola Berlese, and of material representing Anystipalpus livshitsi (Eidelberg) new combination and two new species, A. labiduricola n. sp. and A. kazemii n. sp. Anystipalpus nataliae (Eidelberg) new combination and Anystipalpus ukrainicus (Sklyar) new combination are determined to be junior synonyms of A. percicola Berlese and A. livshitsi (Eidelberg), respectively, new synonymies. The genus is known thus far only from adult females phoretic under the elytra of carabid beetles and the tegmina of labidurid earwigs in Eurasia. The relationships between it and the closely related Antennoseius Berlese, 1916 and Vitzthumia Thor, 1930, are reviewed, and the options for the family level placement of these genera are reconsidered. Attention is given to some gnathosomatic attributes that are commonly overlooked in description of species of these closely related genera. Phoresy and the role of adult female morphs in the life history of these mites, as well as the extraordinary phoretic association of one species with earwigs are discussed.

Published: July 2019

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.
Batillipes pennaki Marcus, 1946 (Arthrotardigrada: Batillipedidae): deciphering a species complex
Authors: SANTOS ERIKA , VEIGA PURI , RUBAL MARCOS , BARTELS PAUL J. , DA ROCHA CLÉLIA M. C. , FONTOURA PAULO
Published: July 2019

Batillipes pennaki has been considered a common and a cosmopolitan marine tardigrade species. However, the original diagnosis of this species is very incomplete, and consequently there is a high probability of incorrect records. Therefore, a comparative analysis of quantitative and qualitative morphological characters among eight different populations from the Atlantic basin was done in this study to investigate if B. pennaki is a complex of similar species, each with a restricted distribution range. The result of discriminant analyses showed clear morphometric differences between populations that were arranged into three main groups, distinguishing Western Atlantic populations, Eastern Atlantic populations and a Mediterranean population. Furthermore, the result of analyses of morphological structures revealed peculiarities of some traits with taxonomic relevance, such as leg IV sensory organs and primary clavae, consistent with the clusters revealed by quantitative data, allowing us to distinguish three different pseudocryptic species and supporting the hypothesis that B. pennaki is a species complex.
The Thermohaline Modes of the Global Ocean
Authors: Pauthenet Etienne , Roquet Fabien , Madec Gurvan , Sallée Jean-Baptiste , Nerini David
Published: July 2019

The first 2000 m of the global thermohaline structure of the ocean are statistically decomposed into vertical thermohaline modes, using a multivariate functional principal component analysis (FPCA). This method is applied on the Monthly Isopycnal and Mixed-Layer Ocean Climatology (MIMOC). The first three modes account for 92% of the joint temperature and salinity (T–S) variance, which yields a surprisingly good reduction of dimensionality. The first mode (69% of the variance) is related to the thermocline depth and delineates the subtropical gyres. The second mode (18%) is mostly driven by salinity and mainly displays the asymmetry between the North Pacific and Atlantic basins and the salty circumpolar deep waters in the Southern Ocean. The third mode (5%) identifies the low- and high-salinity intermediate waters, covarying with the freshwater inputs of the upper ocean. The representation of the ocean in the space defined by the first three modes offers a simple visualization of the global thermohaline structure that strikingly emphasizes the role of the Southern Ocean in linking and distributing water masses to the other basins. The vertical thermohaline modes offer a convenient framework for model and observation data comparison. This is illustrated by projecting the repeated Pacific section P16 together with profiles from the Array for Real-Time Geostrophic Oceanography (ARGO) global array of profiling floats on the modes defined with the climatology MIMOC. These thermohaline modes have a potential for water mass identification and robust analysis of heat and salt content.
Open Airway Surgery in a Paraplegic: The Importance of an Adequate Cough
Authors: Amin Shaunak N. , Rodney Jennifer P. , Gelbard Alexander
Published: July 2019

Objectives:

To describe a case of open airway surgery with postoperative respiratory complications in a paraplegic woman and to review the unique respiratory physiology seen in patients with a history of cervical or thoracic spinal cord injury (SCI).

Methods

Case report and literature review.

Results:

We describe the case of a 25-year-old paraplegic who developed tracheal stenosis after tracheotomy, eventually requiring tracheal resection and re-anastomosis. Her postoperative course was complicated by mucus plugging and severe atelectasis, necessitating reintubation. After extubation, the patient reported difficulty expectorating secretions ever since her SCI, requiring manual abdominal pressure from her family members to assist her when she needed to cough.

Conclusion:

This first report of cricotracheal resection in a patient with paraplegia following SCI highlights the importance of an adequate cough and demonstrates the unique respiratory management necessary for patients with SCI.
Self-Perceived Psychophysical Well-Being of Young Competitive Swimmers With Physical or Intellectual Impairment

Published: July 2019

Regular practice of sport activities yields psychophysical benefits for both the general population and persons affected by physical or intellectual impairments. Practicing competitive sport may add further value to these benefits. The objective of this observational cross-sectional study was to investigate the role of competitive sport practice in enhancing self-perceived psychophysical well-being of some select participants, using the Psychological General Well-Being Index and the Short Form-12 indices. We recruited at national events 100 young Italian competitive swimmers affected by physical or intellectual impairment. These respondents' results were compared with those of a control group of 100 Italian participants who did not practice competitive sport but who were also affected by physical or intellectual impairment, randomly selected from rehabilitation clinics and communities of young people with disabilities. Scores of psychological and emotional well-being were higher by 40% or more for the practitioners of competitive sport ( p < .0001; Cohen's effect size d ≥ 1.3). While our study's results suggest possible positive psychophysical benefits to competitive sport practice for young people affected by physical or intellectual impairment, longitudinal research is needed to be certain that our results are not due to self-selection into sports participation of those persons with disabilities who have a uniquely higher sense of well-being.
The Earnings and Income Mobility Consequences of Attending a Historically Black College/University: Matching Estimates From 2015 U.S. Department of Education College Scorecard Data

Published: July 2019

This article considers the labor market consequences of attending a Historically Black College/University (HBCU). With 2015 U.S. Department of Education College Scorecard Data, we use a matching estimator to identify and estimate the treatment effect of HBCU attendance on median earnings, earnings relative to a high school graduate, and income relative to that of the household at the time of initial enrollment, 6 and 10 years after attendance. Our treatment effect parameter estimates suggest that once we account for the differential return to college majors, the urban wage premium, and the proportionality/dependence of the labor market return of Black student college attendees on the share of a college/university’s student population that is Black, there is a long-run earnings premium associated with HBCU attendance. In addition, for HBCUs in general, we find that there is a population of students who would realize a positive labor market premium—as high as approximately 42%—and earn more than a high school graduate if they were to attend an HBCU. With respect to intergenerational income mobility, we find that HBCU attendance enables their actual and potential attendees to move to a higher quantile of income relative to their households in the long run.
Circadian Vision in Zebrafish: From Molecule to Cell and from Neural Network to Behavior
Authors: Li Lei
Published: July 2019

Most visual system functions, such as opsin gene expression, retinal neural transmission, light perception, and visual sensitivity, display robust day-night rhythms. The rhythms persist in constant lighting conditions, suggesting the involvement of endogenous circadian clocks. While the circadian pacemakers that control the rhythms of animal behaviors are mostly found in the forebrain and midbrain, self-sustained circadian oscillators are also present in the neural retina, where they play important roles in the regulation of circadian vision. This review highlights some of the correlative studies of the circadian control of visual system functions in zebrafish. Because zebrafish maintain a high evolutionary proximity to mammals, the findings from zebrafish research may provide insights for a better understanding of the mechanisms of circadian vision in other vertebrate species including humans.
Madness, Medicine and Miracle in Twelfth-Century England
Authors: Trenery Claire
Published: July 2019

This monograph provides a fresh perspective on how madness was defined and diagnosed as a condition of the mind in the Middle Ages and what effects it was thought to have on sufferers. Records of miracles that were believed to have been performed by saints reveal details of illnesses and injuries that afflicted medieval people. In the twelfth century, such records became increasingly medicalized and naturalized as the monks who recorded them gained access to Greek and Arabic medical material, newly translated into Latin. Nonetheless, by exploring nuances and patterns across the cults of five English saints, this book shows that hagiographical representations of madness were shaped as much by the individual circumstances of their recording as they were by new medical and theological standards.
A Vital Report on Trends in Media Freedom and Its Link with the Future of Democracy
Authors: Mudgal Vipul
Published: July 2019

UNESCO’s report World Trends in Freedom of Expression and Media Development is aimed at creating a heightened awareness about human development, media freedom and public access to information for which an enabling environment hinges on peoples’ awareness and participation. The report is like a tool for implementing UN’s Sustainable Development Goals (SDGs) which have a deadline of 2030. It reaffirms that an impartial and responsible media will thrive only in a just and sensible society with good governance, strong democratic institutions, and a healthy media landscape. It calls for media pluralism, diverse, transparent and non-monopolistic ownership, and a healthy communication environment. The report warns of authoritarianism of governments and goes on to show that the issue of media independence matters for both protecting freedom of speech and democracy.
Problem Talk in Management Group Meetings
Authors: Laapotti Tomi , Mikkola Leena
Published: July 2019

This naturalistic study focuses on problem talk (PT) in hospital management group meetings. The study aims to understand how PT constitutes the hospital organization through the different uses of PT within the meetings, and, therefore, to understand the organizing role of these meetings. The communication as constitutive of organization (CCO) perspective forms the theoretical background of the research. The results of the qualitative analysis show that PT comprises many intertwined tasks that aim to perform the meetings, enhance problem solving, and maintain the relational level of group life. Thus, PT is much more than merely solving problems. In PT, problems are discussed from the viewpoints of the group and the organization. Meetings as an institution and as a nonhuman agent affect organizing because they influence both the group’s communication and organizational processes. Future research on groups should develop the use of the CCO concept of nonhuman agency.
Numerical analysis of damage and failure behavior of concrete
Authors: Brünig Michael , Michalski Alexander
Published: July 2019

The paper discusses an anisotropic continuum damage model for concrete and its numerical implementation into a finite element program to provide an efficient approach suitable for boundary-value problems analyzing nonlinear concrete behavior. The phenomenological continuum approach is based on kinematic description of damage. Irreversible deformation behavior as well as volume increase of material samples even under compression loading are simulated by a damage strain rate tensor. The elastic constitutive equations are affected by damage strain tensors modeling decrease of elastic material parameters. The numerical procedure is based on the damage predictor–elastic corrector technique and the corresponding consistent tangent modulus is presented. Different experiments have been performed and deformation fields are analyzed by digital image correlation technique. Numerical simulations of the experiments show good agreement of the results and elucidate stress and damage states in the specimens. They allow prediction of failure modes of the tested specimens agreeing well with photographs of fractured cylinders and cubes. They also demonstrate the efficiency and the applicability of the proposed continuum damage model.
Mind Wandering (Internal Distractibility) in ADHD: A Literature Review
Authors: Lanier Jane , Noyes Elizabeth , Biederman Joseph
Published: July 2019

Objective: Mind wandering, the unintended shifting of attention from a task, has been previously associated with symptoms of ADHD. To this end, we conducted a literature search to investigate the association between mind wandering and ADHD. Method: We conducted a systematic search of the literature of relevant articles assessing mind wandering and ADHD in PubMed, PsycINFO/OVID, and Medline. Included were original articles in English that had operationalized definitions of ADHD and mind wandering, adequate sample size, and reliance on statistical evaluation of findings. Excluded were reviews, opinions, and case reports. Results: Only nine studies met our a priori inclusion and exclusion criteria ( N = 8 in adults; N = 1 in pediatrics). Findings suggest that ADHD is frequently associated with spontaneous mind wandering and when present heralds more functional impairments. Conclusion: The limited research on mind wandering in ADHD indicates that it is prevalent and morbid supporting further research on the subject.
Maturation of arteriovenous fistulas in patients with ventricular assist devices
Authors: Salem Karim M , Abou Ali Adham N , Sue Erika , Mohapatra Abhisekh , Eid Raymond E , Kormos Robert L , Chaer Rabih A , Avgerinos Efthymios D
Published: July 2019

Objective:

Postoperative renal dysfunction necessitating hemodialysis after implantation of ventricular assist devices presents a challenge with respect to establishment of hemodialysis access. Lack of pulsatile flow has led to concerns that arteriovenous fistulas will not mature. This study aims to evaluate arteriovenous fistula as a method of hemodialysis.

Methods:

Consecutive patients who underwent implantation of a ventricular assist device between 1988 and 2016 with a subsequent need for hemodialysis were identified. Retrospective data were collected for patients requiring hemodialysis through an arteriovenous fistula or arteriovenous graft. Access flow rates and duration of patency are reported.

Results:

Sixty-four patients were identified (10 required long-term hemodialysis, 5 via arteriovenous fistula, 1 via arteriovenous graft). All six patients receiving long-term hemodialysis access were on continuous-flow ventricular assist devices. Brachiocephalic arteriovenous fistulas were performed in all arteriovenous fistula patients, and the average preoperative vein diameter was 4.1 ± 0.9 mm. On 30-day follow-up, the average flow rate was 1262 ± 643 mL/min (880–2220). In arteriovenous fistula patients, one died at 30 days, one arteriovenous fistula required ligation for steal syndrome at 5 months, and one was abandoned after 10.7 months for low flow. Of remaining fistulas, one was converted to an arteriovenous graft at 1.7 years for malfunction (with 5.3 month patency), and one remains open at 4.0 years.

Conclusion:

Arteriovenous fistulas should be considered in selected patients with ventricular assist devices as a means of long-term hemodialysis access to avoid use of catheters. Maturation and usage of primary arteriovenous fistulas is possible despite lack of pulsatile flow.
A Genome Model to Explain Major Features of Neurodevelopmental Disorders in Newborns
Authors: Friedenson Bernard
Published: July 2019

The purpose of this study was to test the hypothesis that infections are linked to chromosomal anomalies that cause neurodevelopmental disorders. In children with disorders in the development of their nervous systems, chromosome anomalies known to cause these disorders were compared with foreign DNAs, including known teratogens. Genes essential for neurons, lymphatic drainage, immunity, circulation, angiogenesis, cell barriers, structure, epigenetic and chromatin modifications were all found close together in polyfunctional clusters that were deleted or rearranged in neurodevelopmental disorders. In some patients, epigenetic driver mutations also changed access to large chromosome segments. These changes account for immune, circulatory, and structural deficits that accompany neurologic deficits. Specific and repetitive human DNA encompassing large deletions matched infections and passed rigorous artifact tests. Deletions of up to millions of bases accompanied infection-matching sequences and caused massive changes in human homologies to foreign DNAs. In data from 3 independent studies of private, familial, and recurrent chromosomal rearrangements, massive changes in homologous microbiomes were found and may drive rearrangements and encourage pathogens. At least 1 chromosomal anomaly was found to consist of human DNA fragments with a gap that corresponded to a piece of integrated foreign DNA. Microbial DNAs that match repetitive or specific human DNA segments are thus proposed to interfere with the epigenome and highly active recombination during meiosis, driven by massive changes in human DNA-foreign DNA homologies. Abnormal recombination in gametes produces zygotes containing rare chromosome anomalies that cause neurologic disorders and nonneurologic signs. Neurodevelopmental disorders may be examples of assault on the human genome by foreign DNAs at a critical stage. Some infections may be more likely tolerated because they resemble human DNA segments. Even rare developmental disorders can be screened for homology to infections within altered epigenomes and chromatin structures. Considering effects of foreign DNAs can assist prenatal and genetic counseling, diagnosis, prevention, and early intervention.
Effects of Entomopathogenic Fungi on the Biology of Spodoptera litura (Lepidoptera: Noctuidae) and its Reduviid Predator, Rhynocoris marginatus (Heteroptera: Reduviidae)

Published: July 2019

Entomopathogenic fungi (EPFs), Isaria fumosorosea and Beauveria bassiana, are efficient biological agents in the management of multiple arthropod pests. In this study, the effects of both EPF species on various life stages of Spodoptera litura (F.) (Lepidoptera: Noctuidae) and its natural enemy Rhynocoris marginatus (Fab.) (Hemiptera: Reduviidae) were determined under laboratory conditions. I. fumosorosea significantly ( P < .05) reduced the growth rate of the third and fourth instar larvae of S. litura. For relative consumption rate (RCR), the maximum impact was recorded for I. fumosorosea, which reduced the RCR of the larvae. The larvae of S. litura treated with I. fumosorosea showed significantly lower efficiency of conversion of ingested food (ECI) and the larval mortality rate (58.0%) was also higher compared with B. bassiana (33.3%). Similarly, I. fumosorosea had a significant effect on the pupal formation of S. litura; however, no significant effect was found on adult emergence percentage. To determine the effect of EPF-infected prey on the adult predator, their handling time, predatory rate, consumption rate, and the survival rate were recorded. No significant effect of EPF species on the predation rate was found. Furthermore, no significant difference was found in the survival rate of predators fed on either EPF-infected prey or healthy larvae. The interaction of these EPFs with a reduviid predator suggested that both EPF species, especially I. fumosorosea, could be used together with the predator to boost the biological control of S. litura in commercial crops.

Hermetic digital scroll compressor has been widely used as a small-scale organic Rankine cycle application in the heating, ventilation, and air conditioning systems. A clunking noise issue is recently found in an air conditioning outdoor unit, and the main cause of the noise is experimentally identified to be the impact of the scrolls in the compressor unit during the switching process. The semi-active control methods are thus designed to greatly reduce the noise level by using additional valves to adjust the pressure changing rate within the modulation chamber. The response time for the impact of the scrolls can then be controlled by the added valves. The additional release valve with a smaller diameter pipe parallel to the main valve is tested firstly for its performance. Slower flow rate is produced and the pipe can extend the response time and decrease the speed of the impact process by reducing the pressure changing rate. The use of a discharge valve is also tested for controlling the pressure changing rate inside the chamber. The discharge valve with an opposite effect to the release valve is found useful for solving the noise issue. Both noise and vibration results confirm that the impact noise in the frequency range of interest can be reduced by using the proposed semi-active control methods.
Contested norms in fragmented institutions: Gender equality in South Africa’s development cooperation
Authors: Cold-Ravnkilde Signe Marie
Published: July 2019

Engaging with gender equality norms is increasingly becoming a prerequisite for being considered a legitimate partner in international development cooperation. South Africa has often been acknowledged as having one of the world’s most progressive constitutions for promoting gender equality. However, gender equality norms are heavily contested in the national political context. Situated in the gap between policy and implementation, this article explores how South Africa engages with gender equality norms as a leading actor in South–South Cooperation. It argues that contestations in competing normative environments and organizational restructuring processes are impeding the push for a policy guiding gender equality work in South Africa’s development cooperation.
New kinetic analysis of the Fenton reaction: Critical examination of the free radical – chain reaction concept
Authors: Kremer Mordechai L
Published: July 2019

Using [H2O2] in the molar range, the reaction with Fe2+ has two phases: in the first rapid phase, only a small fraction of the total O2 is evolved; the bulk of the gas is formed in a slow second phase. In interpretations based on the free radical model of Barb et al., the first phase has been identified with the ‘Fenton reaction’ (reaction of Fe2+with H2O2), while the second with catalytic decomposition of H2O2 by Fe3+ ions. This interpretation is not correct. A new analysis of the model shows that (1) it is a chain reaction having no termination steps and (2) the ‘Fenton part’ alone consists of two phases. It starts with rapid evolution of O2 via a five-membered chain reaction (first phase). When [Fe2+] becomes low, evolution of O2 continues in a three-membered chain reaction at a greatly reduced rate (second phase). In later stages of the second phase, Fe3+ catalysis contributes to O2 evolution. Thus, the amount of O2 formed in the rapid phase cannot be identified with the total amount formed in the ‘Fenton reaction’ but only with that formed in its first phase. Computer simulations of O2 evolution based on the model of Barb et al. and rate constants show a definite dependence of this quantity on the initial [H2O2] – in contrast to the experimentally found independence. More satisfactory, but not complete, agreement with measured data could be reached in simulations using a non-radical model. Some of the difficulty has been due to the determination of the exact position of the end of the first phase. The transition between the two phases of the reaction occurs in a short, but finite time interval. It has been shown that the quantity ‘total amount of O2 evolved in the Fenton reaction’ (subtracting the part due to Fe3+catalysis) is not accessible to experimental determination nor to theoretical calculation.

This study introduces the tubular braided structure as a new geosynthetic material for sand reinforcement. The performance of a tubular braid under the influence of similar soil–reinforcement interaction mechanisms has been investigated to emphasize the effect of the reinforcement form on the performance of the reinforced soil composite. For this purpose, three series of interaction element tests including direct shear tests, pull-out tests, and soil stress control tests were conducted on the unreinforced and reinforced sand. Finally, the overall performance of the reinforced foundation bed with the planar and tubular reinforcing textile (with similar materials, properties, texture, and areal density) was evaluated through a series of standard plate load tests. The results indicated that the performance of the sand-braid composite was better compared to the similar typical planar reinforcement, except for the case of pull-out test. Tubular braid resulted in the enhanced shear strength of the reinforced soil composites, mobilization of the excess compressive stress in the enclosed soil inside the tubular braids, reduction in the vertical stress level of the footing model transferred down through the soil bed, the increase of the average bearing capacity of the footing model, and a significant reduction in the footing settlement.
Arp2/3 and Unc45 maintain heterochromatin stability in Drosophila polytene chromosomes

Published: July 2019

Repairing DNA double-strand breaks is particularly challenging in pericentromeric heterochromatin, where the abundance of repeated sequences exacerbates the risk of ectopic recombination. In Drosophila Kc cells, accurate homologous recombination repair of heterochromatic double-strand breaks relies on the relocalization of repair sites to the nuclear periphery before Rad51 recruitment and strand invasion. This movement is driven by Arp2/3-dependent nuclear actin filaments and myosins’ ability to walk along them. Conserved mechanisms enable the relocalization of heterochromatic repair sites in mouse cells, and defects in these pathways lead to massive ectopic recombination in heterochromatin and chromosome rearrangements. In Drosophila polytene chromosomes, extensive DNA movement is blocked by a stiff structure of chromosome bundles. Repair pathways in this context are poorly characterized, and whether heterochromatic double-strand breaks relocalize in these cells is unknown. Here, we show that damage in heterochromatin results in relaxation of the heterochromatic chromocenter, consistent with a dynamic response. Arp2/3, the Arp2/3 activator Scar, and the myosin activator Unc45, are required for heterochromatin stability in polytene cells, suggesting that relocalization enables heterochromatin repair also in this tissue. Together, these studies reveal critical roles for actin polymerization and myosin motors in heterochromatin repair and genome stability across different organisms and tissue types.

Impact statement

Heterochromatin relies on dedicated pathways for ‘safe’ recombinational repair. In mouse and fly cultured cells, DNA double-strand break repair requires the movement of damaged sites away from the heterochromatin ‘domain’ via nuclear actin filaments and myosins. Here, we explore the importance of these pathways in Drosophila salivary gland cells, which feature a stiff bundle of endoreduplicated polytene chromosomes. Repair pathways in polytene chromosomes are largely obscure and how nuclear dynamics operate in this context is unknown. We show that heterochromatin relaxes in response to damage, and relocalization pathways are necessary to prevent abnormal repair and promote the stability of heterochromatic sequences. These results deepen our understanding of DNA damage response mechanisms in polytene chromosomes, revealing unexpected dynamics. It also provides a first understanding of nuclear dynamics responding to replication damage and rDNA breaks, providing a new understanding of the importance of nuclear architecture in genome stability. We expect these discoveries will shed light on tumorigenic processes, including therapy-induced cancer relapses.
On Disruption and Construction, Reflection and Reorganization in Psychotherapist Development: A Taxonomy of Transformative Learning Outcomes
Authors: Watkins C. Edward
Published: July 2019

The beginning period of psychotherapist development has been conceptually and empirically identified as the most difficult and potentially problematic. The budding therapist is struggling to define a therapist identity, settle into the role of being a “helper,” and come to grips with being a helper who can “heal.” That struggle, I contend, is at its core a transformative learning process that involves developing a guiding vision of oneself as therapist, where the shift from becoming to being is made reality. In what follows, I examine transformative learning theory as a framework for enhancing our understanding about the beginning period of therapist development. The specific question that I consider is: What transformative learning outcomes occur for the beginning psychotherapist in the process of developing a therapist identity? I draw on and analogize from Hoggan’s typology of transformative learning outcomes in providing an answer to that question.

Published: July 2019

Internet of Things simulations play significant roles in the diverse kinds of activities in our daily lives and have been extensively researched. Creating and controlling virtual agents in three-dimensional Internet of Things simulations is a key technology for achieving realism in three-dimensional simulations. Given that traditional virtual agent-based approaches have limitations for realism, it is necessary to improve the realism of three-dimensional Internet of Things simulations. This article proposes a Q-Network-based motivation framework that applies a Q-Network to select motivations from desires and hierarchical task network planning to execute actions based on goals of the selected motivations. The desires are to be identified and calculated based on states. Selected motivations will be chosen to determine the goals that agents must achieve. In the experiments, the proposed framework achieved an average accuracy of up to 85.5% when the Q-Network-based motivation model was trained. To verify the Q-Network-based motivation framework, a traditional Q-learning is also applied in the three-dimensional virtual environment. Comparing the results of the two frameworks, the Q-Network-based motivation framework shows better results than those of traditional Q-learning, as the accuracy of the Q-Network-based motivation is higher by 15.58%. The proposed framework can be applied to the diverse kinds of Internet of Things systems such as a training autonomous vehicle. Moreover, the proposed framework can generate big data on animal behaviors for other training systems.
Anti-heroes, wildfire, and the complex visibility of prison labor
Authors: Feldman Lindsey Raisa
Published: July 2019

The vast majority of prison labor goes unnoticed by the public, serving as a microcosm of the invisibility of prisoners as a whole. This perpetuates stereotypical media representations and public perceptions of prison laborers as nothing more than their indentured subjugation. This photo essay presents a more nuanced view of the experience of prison labor. I present images of an exceptional labor program, Arizona’s Inmate Wildfire Program, in order to question what happens when prison labor becomes visible, and when the symbolic markers of incarceration disappear. The program, in which 11 prison crews fight wildfires across the state, is an experiential paradox for its participants. It is at once exploitative, with its low pay for risky work, as well as transformative, with its potential for a re-emergence of complex identities and reclamation of dignity for those involved. Through these images, I argue that the transformative potential of the program is due in part to the program’s visibility, as incarcerated firefighters interact with the public—and their own self-representations—in emergent, meaningful ways. I call to examine the complexities of programs that challenge certain dehumanizing experiences of incarceration while being securely entrenched within the carceral regime.
