Personality Traits among the Various Profiles of Substance Use Disorder Patients: New Evidence Using the DSM-5 Section III Framework
Authors: Moraleda Enrique , Ramírez López Juan , Fernández-Calderón Fermín , Lozano Óscar M. , Diaz-Batanero Carmen
Published: June 2019

Background: The specialized literature provides solid evidence that substance use disorders (SUD) and personality disorders (PD) are interrelated. Given the relative novelty of the Alternative Model for PD, there are still few studies that have analyzed the relationship between the different facets, substance use disorder, and the various consumption profiles. Objective: This paper analyzes the relationship between the facets of the Alternative Model for PD and different substance use disorder profiles, using the facet scores obtained in a sample of substance use disorder patients and comparing these with normative scores. A comparison is also conducted between types of patients. Method: The Personality Inventory for DSM-5-SF was administered to a sample of 289 patients diagnosed with SUD who began treatment for alcohol (ALC), cannabis (CAN), cocaine (COC), or heroin (HER) use disorder. A latent class analysis was conducted and scores obtained for each of the classes were compared with normative scores. Logistic regression analyzes were carried out to determine which facets and domains show the greatest explanatory capacity of belonging to each latent class. Results: Four patient profiles were identified on the basis of their SUD: polydrug use (POLY), COC-HER, ALC, and CAN. When comparing the groups with the normative population, POLY presented higher scores on all the domains, COC-HER and ALC on all domains except antagonism, and CAN showed higher scores on detachment and psychoticism. The CAN cluster presented lower scores than the other 3 groups in different domains. No statistically significant differences were observed on any domain between the groups POLY and COC – HER, while differences were found between the classes POLY and ALC for the detachment domain. Conclusions: The results help to identify the personality profiles associated with various SUD profiles. In particular, patients from the groups POLY, COC-HER, and ALC present high scores on pathological facets related to borderline PD and schizotypal PD (all 3), and antisocial PD (POLY), while the CAN cluster is more normalized and its pathological facets are related to the schizotypal PD. Patients with POLY have a greater tendency toward pathological personality, with the involvement of a large number of facets, while COC-HER and ALC show a slightly less severe profile, and CAN users are characterized by lower scores, but high detachment and psychoticism.
Digital Analysis in Breast Imaging
Authors: Negrão de Figueiredo Giovanna , Ingrisch Michael , Fallenberg Eva Maria
Published: June 2019

Breast imaging is a multimodal approach that plays an essential role in the diagnosis of breast cancer. Mammography, sonography, magnetic resonance, and image-guided biopsy are imaging techniques used to search for malignant changes in the breast or precursors of malignant changes in, e.g., screening programs or follow-ups after breast cancer treatment. However, these methods still have some disadvantages such as interobserver variability and the mammography sensitivity in women with radiologically dense breasts. In order to overcome these difficulties and decrease the number of false positive findings, improvements in imaging analysis with the help of artificial intelligence are constantly being developed and tested. In addition, the extraction and correlation of imaging features with special tumor characteristics and genetics of the patients in order to get more information about treatment response, prognosis, and also cancer risk are coming more and more in focus. The aim of this review is to address recent developments in digital analysis of images and demonstrate their potential value in multimodal breast imaging.
Principe de Non-Contradiction, Négation et Pluralisme Logique

"Que faut-il pour faire un monde ? À cette question classique, Francis Wolff répondait en 1997 ni de tout (car le monde n’est pas une collection de choses, une totalité entendue au sens purement quantitatif ou extensionnel d’un inventaire exhaustif), ni seulement du tout (car le monde ne répond pas non plus à la seule exigence d’universalité ou d’universalisation de l’expérience), mais « des noms, des verbes et des pronoms personnels ».

Published: June 2019

Background:

Postoperative transcatheter interventions (TCIs) are performed after congenital heart surgery to treat residual or recurrent anatomic lesions. We used the Society of Thoracic Surgeons Congenital Heart Surgery Database to evaluate rates of postoperative TCIs, center variability, and to determine whether center approaches to postoperative TCI might be associated with outcomes.

Methods and Results:

Patients <18 years undergoing an index operation (2010–2016) were included. We determined predischarge postoperative TCI rates and used multivariable modeling, adjusting for patient factors and case complexity, to evaluate the association between center risk-adjusted postoperative TCI rates and risk-adjusted outcomes (operative mortality, post-TCI mortality, and failure-to-rescue). Postoperative TCI was performed after 2615/105 742 (2.5%) index operations and after 1443/25 416 (5.7%) highest complexity operations (STAT [Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Mortality Score] Mortality Category 4 and 5). Median (interquartile range) age of patients undergoing TCI was 2.7 (0.2–8.0) months with 43% performed in neonates. There was a wide center variability across the 107 included centers with risk-adjusted rates of postoperative TCI ranging from 0.0% to 8.0% overall and 0.0% to 20.7% for STAT 4 and 5 cases. Postoperative TCI was associated with higher risk-adjusted odds of operative mortality (odds ratio, 4.06; 95% CI, 3.60–4.58). Centers with higher postoperative TCI rates had higher overall operative mortality (
R
2
=0.23;
P
=0.02) but did not have higher post-TCI mortality (
P
=0.10). There was no correlation between center TCI rates and failure-to-rescue (
P
=0.19).

Conclusions:

Patients undergoing postoperative TCI represent a high-risk cohort. Wide center variability suggests the potential for improving outcomes, but further study is necessary to better understand optimal approaches.
The Age of “Amok”
Authors: Vogl Joseph
Published: June 2019

The proliferation of mass-shootings in the United States since the 1960s has produced a character profile of largely unremarkable, middleclass male culprits who transform particular places of civil peace – schools, universities, shopping malls – into landscapes of war. On the one hand, the lack of clear motives has led mystified psychiatric experts to draw correlations between such events and “running amok” – the phenomenon of sudden outbursts of homicidal violence observed since early modernity in Southeast Asia. On the other hand, the details of how such acts are carried out as well as the notes of some perpetrators suggest that mass-shootings could also be understood as “interpretations” of American postwar society: from the “lonely crowd” of suburbia via “Reaganomics” to the present politics of fear and resentment to a society of preemptive control.
Desert Blooms
Authors: Chaudhary Zahid R.
Published: June 2019

This essay considers the place of abstraction in documentary photography, a genre whose primary aesthetic-political commitment is usually assumed to be on the side of figuration, denotation, and facticity. Taking up photographer Fazal Sheikh's photographic series Desert Bloom, which records natural and human-made disturbances in the Naqab/Negev desert, the essay considers artistic abstraction in relation to other forms of economic, juridical, and political abstraction critical to settler colonialism in particular and capitalism more generally. How might abstraction be the very condition of politics? What might this imply for our understandings of documentary aesthetics?
Tensions between the Study of Gender and Religion
Authors: Duderija Adis
Published: June 2019

In this article, I discuss the tensions between patriarchal and non-patriarchal interpretations of the Islamic tradition and some of the factors which contribute to the engendering of both. In order to contextualize the main discussion in the first part of the article, I outline the historical tensions between the study of religion and gender in general. The question of whether the culturally organizing function of gender is to be inevitably linked to the formation and perpetuation of patriarchal religion in general, and Islam in particular, is explored, or whether religion, including the case of Islam, can be a source of non-patriarchal values and ethics. In the second part, I discuss some of the most prominent factors which contribute to patriarchal interpretations of the Islamic tradition by grouping them, from the perspective of the individual interpreter, into those which pertain to personal opinion regarding the nature of two genders, Sitz im Leben, and interpretational methodology (manhaj). In the context of non-patriarchal interpretations of the Islamic tradition, I discuss its main delineating features and show, by using the work of a contemporary reformist Iranian scholar, H. Y. Eshkevari (b. 1949/1950), how the contemporary non-patriarchal interpretations of the Islamic tradition are sensitive to how both patriarchy and gender influence the process of interpretation.
Introduction: Safe Areas as a Response to Humanitarian Crises?
Authors: Jacob Daniel , Recchia Stefano
Published: June 2019

Internationally proclaimed safe areas do not aim to end ongoing wars. Instead, their more limited goal is to create islands of temporary refuge where threatened civilians can find shelter. As intuitively compelling as the idea of safe areas may seem, however, it raises numerous practical and ethical questions. The articles in this special issue draw on history, moral philosophy and political science in order to assess whether safe areas are indeed an appropriate response to humanitarian crises.
The Papyrus from the ‘Musician’s Tomb’ in Daphne (MΠ 7449, 8517-8523)
Authors: Karamanou Ioanna
Published: June 2019

The author explores the evidence for the earliest Greek papyrus discovered so far (430/425 bc). It was unearthed as part of a collection of writing implements along with musical instruments in a tomb in Daphne in 1981. She attempts to situate the available evidence in context, by investigating how it could be mapped onto the framework of papyrological research and its contemporary literary and cultural milieu.
Echo’s Bones and the Metamorphoses of the Voice
Authors: LeVen Pauline
Published: June 2019

This article concentrates on the description of the demise of Echo in the Ovidian narrative of Echo and Narcissus in Metamorphoses 3. I argue that a pun in the line vox tantum atque ossa supersunt (3.398) encapsulates the problem at the heart of the myth: rather than being a reflection on the origins of the echo and the delusion of the senses, the myth of Echo is a meditation on the nature of the voice.
Musical Themes and Private Art in the Augustan Age
Authors: Castaldo Daniela
Published: June 2019

Some musical themes represented in terra sigillata reflect the political propaganda of the Augustan regime, as in the presence of Apollo citharoedus, of Sirens and of Hercules with the Muses. This visual repertory shares many features with the Augustan poets (especially the elegists) and with other private art of the Augustan period. Arretine ware potters often included Dionysiac, symposiastic and erotic scenes in their repertory, moving well beyond Augustus’ official program. They recall formal and cultural models of the Hellenistic era.
Antistrophes or Antistrophic Couples?
Authors: Ercoles Marco
Published: June 2019

On a particular use of the substantive adjective (ἡ) ἀντίστροφος, “piece of the song in response to the strophe”, “antistrophe”: in some passages of the Aristotelian corpus (Rh. 1409a27, a 27, b 27, [Prob.] 19.15 and 19.30) it is used, generally in the plural, to refer to the whole antistrophic pair, not only to the antistrophe. Such a peculiar use, generally unrecognized, should be integrated into modern dictionaries of Ancient Greek.
An unorthodox, new endemic species in New Caledonian Marsdenia (Apocynaceae, Asclepiadoideae, Marsdenieae)
Authors: GÂTEBLÉ GILDAS , FLEUROT DOMINIQUE , MEVE ULRICH , LIEDE-SCHUMANN SIGRID
Published: June 2019

In the course of the writing of the Flore de la Nouvelle-Calédonie treatment for Asclepiadoideae, Periplocoideae and Secamonoideae, several new species have already arisen partly due to more intensive field work and to a renewed interest in this group of plants. In December 2018, another striking and unorthodox new species was spotted and collected on the flanks of the Kopéto massif mining site. Because this new species has morphological characters from three genera (Dischidia, Gymnema and Marsdenia), further studies, especially molecular, were needed to assess its relationships. These studies show it as a member of one of the New Caledonian Marsdenia subclades. We herein propose to describe it as Marsdenia goromotoorum Gâteblé, Fleurot, Meve & Liede, the only species of Marsdenia in New Caledonia lacking both corolline and gynostegial coronas. It is a micro-endemic species with pinkish-red tubular flowers, growing on serpentines and known from only eight plants. Due to the anthropogenic fire threat, we propose to consider it as Critically Endangered.
Macrobrachium sbordonii (Decapoda: Palaemonidae), a new stygobitic species of freshwater prawn from Chiapas Mexico
Authors: MEJÍA-ORTÍZ LUIS M. , BALDARI FABIOLA , LÓPEZ-MEJÍA MARILÚ
Published: June 2019

The fourth stygobitic species of the genus Macrobrachium from caves in America is described. Macrobrachium sbordonii, a new species inhabiting a cave of Chiapas Mexico, is similar to M. villalobosi, M. acheronthium and M. catonium in exhibiting reduced eyes, unpigmentated body and enlargement of ambulatory appendages. It differs from these in length of the first pereiopod and relative proportions of the articles of the second pereiopod, pigmentation degrees on eyes, number of rostral spines, proportions of the scaphocerite, and relative proportions of the carpus and propodus of the first pereiopod. Macrobrachium sbordonii occurs in the inner lake of the Sistema de La Lucha, a cave located near the Chiapas-Oaxaca border, in the Tehuantepec Itsmus Region.

Published: June 2019

Aczél established the genus Idiopyrgota to place a single species, I. setiventris, based on an analysis of eight females from Mato Grosso do Sul, Brazil. The species is redescribed on the basis of new available material from the type locality as well as one female specimen from Jujuy, Argentina (this is the first record of this species in this area). Adult anatomical structures are described and illustrated in detail, including information of the previously unknown male and female spermathecae. This study provides better grounds for the recognition of the taxon.
Revision of Holarctic Teleiodini (Lepidoptera: Gelechiidae)
Authors: LEE SANGMI , Brown Richard L.
Published: June 2019

The 25 genera of Teleiodini (Lepidoptera: Gelechiidae) occurring in the Holarctic Region are revised. A new genus and new species, Arcutelphusa talladega, are described from Alabama and Mississippi, United States. Evippe Chambers (1873a) is synonymized with Agnippe Chambers (1872a), Hapalosaris Meyrick (1917) is synonymized with Coleotechnites Chambers (1880b), and Laris Omelko (1988) is synonymized with Parastenolechia Kanazawa (1985). Telphusa is restricted to three species, and Teleiodes is restricted to four species. A key to genera and a checklist of species, which includes 28 new combinations, are provided. Each generic treatment includes descriptions of imagos, including venation and genitalia, and immature stages so far as known, larval hosts, diversity and distribution, and illustrations of selected species.
Description of the Yunnan shoot borer, Tomicus yunnanensis Kirkendall & Faccoli sp. n. (Curculionidae, Scolytinae), an unusually aggressive pine shoot beetle from southern China, with a key to the species of Tomicus
Authors: KIRKENDALL LAWRENCE R. , FACCOLI MASSIMO , YE HUI
Published: June 2019

We describe a new and highly aggressive species of pine shoot beetle, Tomicus yunnanensis Kirkendall & Faccoli, which has been decimating Pinus yunnanensis forests in southwest China for almost three decades. This species was confused with T. piniperda until recent molecular studies showed the SW China populations to be quite divergent from T. piniperda of northeast China and Europe. The clearest morphological differences between these two species lie in the surface sculpture of the elytra: the new species has more widely spaced interstrial granules on the elytral disc, the punctures of interstria 2 on the declivity arranged irregularly and those of striae 1 and 3 smaller. The new species also has dense small hairs on the tip of the antennal club, while T. piniperda has only scattered small hairs on that segment. Mature T. piniperda specimens are uniformly black, while those of T. yunnanensis have the bulk of the elytra lighter than the base of the elytra and the pronotum. The new species is actually more similar to the Mediterranean species T. destruens, which differs in geographical distribution and in having the punctures of interstria 2 dense on the declivity and light-colored antennae. Species of Tomicus are of general concern to foresters because of their impact on conifer growth, but good illustrations for many species are lacking. We here provide a detailed key to all seven species of the genus (T. minor, T. piniperda, T. destruens, T. brevipilosus, T. yunnanensis and the virtually unknown T. puellus and T. pilifer) as well as diagnostic photographs and drawings. We summarize the biological differences between the new species and T. piniperda and recommend improved communication between taxonomists and forest entomologists, as avoidable taxonomic confusion such as that of T. yunnanensis and T. destruens with T. piniperda hinders the combatting of outbreaks of forest insects.
Luciobarbus kottelati, a new species of barbel (Teleostei: Cyprinidae) from the Buyuk Menderes River, Turkey, with rediagnose of L. lydianus
Authors: TURAN DAVUT , EKMEKÇİ F. GÜLER , İLHAN ALİ , ENGİN SEMİH
Published: June 2019

Luciobarbus kottelati, new species, is described from the River Büyük Menderes, Aegean Sea drainage, Turkey. It is distinguished from all other species of Luciobarbus in Europe and western Anatolia by the pelvic-fin origin markedly in front of the dorsal-fin origin (vs. behind). Luciobarbus lydianus, considered to be a synonym of L. pectoralis by most recent authors is a valid species and is rediagnosed.
Puntius kamalika, a new species of barb from Sri Lanka (Teleostei: Cyprinidae)
Authors: SILVA ANJANA , MADUWAGE KALANA , PETHIYAGODA ROHAN
Published: June 2019

Since its first record from the island in 1912, the barb Puntius amphibius Valenciennes has regularly featured in Sri Lanka’s ichthyofaunal inventories. Recent work has shown, however, that the name P. amphibius should be reserved for a species originally collected from Bombay, India, and described by Achille Valenciennes in 1842, now known only from its lectotype. The Sri Lankan fish hitherto known by this name is an undescribed species. Puntius kamalika, new species, is distinguished from all Sri Lankan and peninsular-Indian congeners by having (in addition to a suite of mensural characters) ½4/1/2½ scales in transverse line between mid-dorsal scale row and pelvic-fin origin and lacking any prominent markings on fins and body in both living and preserved examples. The new species is widely distributed in the island’s wet-zone lowlands (rainfall > 2,500 mm yr -1 ), where it occurs in streams, rivers and marshes between the Kelani-River basin draining to the island’s west, and the Gin River basin to the south. It is locally common.

A new genus and species, Phalloleucon abyssalis, of the cumacean family Leuconidae from the Peru Basin is introduced. The new genus is characterised in having penial lobes and one pair of pleopods in males. It is suggested that the species Eudorella redacticruris Watling and McCann, 1997 is transfered into a new leuconid genus: Pseudeudorella.
A new species of flightless, jumping, alpine moth of the genus Thyrocopa from Hawaii (Lepidoptera: Xyloryctidae: Xyloryctinae)
Authors: MEDEIROS MATTHEW J.
Published: June 2019

A new species of brachypterous, flightless, jumping alpine Thyrocopa moth, T. kikaelekea, is described from Hawaii Island. This new species is similar to T. apatela (Walsingham), another flightless species from Maui Island. Thyrocopa kikaelekea is hypothesized not to be the sister taxon to T. apatela, instead representing an independent loss of flight.
Review of the Neotropical blackfly subgenus Chirostilbia Enderlein (Diptera: Simuliidae) based on adults and pupal morphology
Authors: HERNANDEZ LUIS MIGUEL , SHELLEY ANTHONY JOHN , DE LUNA DIAS ANTONIO PAULINO ANDRADE , MAIA-HERZOG MARILZA
Published: June 2019

The species of the subgenus Chirostilbia are reviewed based on the adult and pupal morphology. All main taxonomic characters are fully illustrated with colour digital images and keys for species identification are given. Taxonomic discussions for each species and summaries of their distribution and biology are also provided. Thirteen species are now considered to be valid in the subgenus Chirostilbia. Since they are similar morphologically no separation into species groupshas been attempted. Lectotypes are designated for the following species: S. distinctum Lutz and Trichodagmia lutziana Enderlein [= S. pertinax Kollar]. Simulium nilesi Rambajan is transferred from its synonymy with S. perflavum Roubaud in the subgenus Psilopelmia Enderlein to Chirostilbia as a junior synonym of S. subpallidum Lutz. The thoracic pattern of the male of S. empascae is described and illustrated for the first time.
Finding the best sequence in flexible and stiff composite laminates interleaved by nanofibers
Authors: Saghafi Hamed , Ghaffarian Seyed R , Yademellat Hesam , Heidary Hossein
Published: June 2019

The brittle nature of thermoset-based composite laminates restricts the application of these materials in various industries. One of the most effective methods for resolving this problem is interleaving the laminate by nanofibrous mats. Applying nanofibers between all layers is very costly and time-consuming. Therefore, the efficiency of using nanofibers in half of the layers for various interleaf sequences is investigated in this study. On the other hand, since the damage pattern is different in thick and thin laminates under impact, its effect is also considered. Cohesive parameters are required for impact modeling in ABAQUS, so they were obtained by mode-I and mode-II fracture tests and numerical studies. The results showed that the best position for interleaving the nanofibers is mid-layers and top layers (near impact point) in thin (flexible) and thick (stiff) laminates, respectively. If it is not possible to predict the damage penetration through the thickness, putting nanofibers in the top section of the laminate is suggested.
Race, Gender, and Disability and the Risk for Juvenile Justice Contact
Authors: Mendoza Martin , Blake Jamilia J. , Marchbanks Miner P. , Ragan Kelsey
Published: June 2019

Exclusionary school discipline has received national attention due to its association with juvenile justice contact. Research has demonstrated support for links between exclusionary discipline and negative outcomes such as school dropout and juvenile justice involvement. The purpose of this study was to examine the intersections of race, gender, and disability in explaining the risk for juvenile justice contact using a state database, representing a sample of adolescent students. Controlling for individual, school, and community characteristics that are associated with juvenile justice contact such as, race/ethnicity, previous years’ discipline rate, student retention from previous year, primary disability, whether the campus is a Title I school, as well as student body size and diversity, results suggest that disproportionality is prevalent when examining juvenile justice contacts, but the relationship among race, gender, disability, and discipline is a complicated one. Implications for understanding juvenile justice contact outcomes and future research for advancing the field are discussed.
An Exploratory Study of Veterinary Professionals’ Self-Reported Support of Bereaved Clients Before, During, and After Companion Animal Euthanasia in Southwestern Ontario, Canada
Authors: Matte Alisha R. , Khosa Deep K. , Meehan Michael P. , Coe Jason B. , Niel Lee
Published: June 2019

Veterinary professionals are recognized as an important source of support for many veterinary clients, particularly during companion animal euthanasia and end-of-life care. While many veterinary professionals recognize the importance of their role, many also report feeling unsure about what methods of support are most effective. Furthermore, few evidence-based guidelines currently exist to inform veterinary professionals on the support of grieving clients. To begin bridging this gap, this study qualitatively explored how veterinary professionals currently report supporting grieving clients before, during, and after companion animal euthanasia. Findings suggest that veterinary participants in this study strive to be meaningful sources of support for grieving clients and employ an array of support practice to do so. However, opportunities exist for veterinary professionals to better explore clients’ needs, expectations, and feelings as they relate to companion animal euthanasia, including offering more grief-related resources and access to professional counseling services.
Evidence That “Voluntary” Versus “Involuntary” Retrieval Is a Fluency-Based Attribution
Authors: Sanson Mevagh , Cardwell Brittany A. , Rasmussen Anne S. , Garry Maryanne
Published: June 2019

Our memories can come to mind either voluntarily—after we intended to retrieve them—or, involuntarily—without our intent. Studies often rely upon subjects themselves to classify their memories as voluntary or involuntary. But how well do subjects perform this task? There is reason to suspect that subjects sometimes base these classifications of intent on feelings of fluency—that is, ease of retrieval—leading them to misclassify their memories. In four experiments, we investigated the extent to which making an experience of voluntary retrieval feel fluent leads subjects to ascribe involuntary attributes to that retrieval. Our findings provide the first experimental demonstration that when subjects intentionally, yet fluently, bring a memory to mind, they may mistakenly judge that the retrieval occurred without intent.

Authors: Mariz Bruno Augusto Linhares Almeida , Sánchez-Romero Celeste , Alvarado Nelson Alejandro Padron , Campos Edgar Manuel Muñoz , Almeida Oslei Paes de , Martínez-Pedraza Ricardo
Published: June 2019

Diffuse cutaneous leishmaniasis is a rare chronic infectious disease, associated with Leishmania mexicana and L. amazonensis, presenting as multiple non-ulcerative painless nodules, with a tendency to relapse soon after treatment. We report a case of a 56-year-old Mexican woman exhibiting nodular lesions, plaques, crusts and scars involving the whole body. A solitary nodule was present at the junction between hard and soft palates. Diffuse cutaneous leishmaniasis is a disfiguring disease resulting in severe scarring if untreated.
“A More Thorough Resistance”? Coalition, Critique, and the Intersectional Promise of Queer Theory
Authors: Gambino Elena
Published: June 2019

Queer theorists have long staked their politics in an engagement with intersectionality. Yet intersectional scholars have been some of queer theory’s most vocal critics, decrying its failure to adequately engage persistent inequalities. I approach this seeming paradox in three parts. First, I situate intersectionality within the field of critical theory, arguing that it shares critical theory’s view of power. Both traditions, I argue, understand power to generate the very marginalized figures that it subordinates. Second, while intersectional and queer theories share this critical insight, the two frameworks offer fundamentally different understandings of what constitutes a democratic politics of redress. Where intersectional theorists promote coalition-building between differently marginalized subjects, queer theorists tend to figure sexually marginalized subjects as exemplary democratic agents. Finally, I argue that this slippage in conceptions of democracy has had negative consequences for critical theory and highlights the difficult but essential role of coalition as a political resource.
The influence of behavioral and emotional characteristics on academic achievement of middle school students: A growth modeling approach
Authors: Park Yujeong , Seo Dong Gi , Park Jaekook , Kim Byungkeon , Choi Jeongwook
Published: June 2019

The purpose of this study was to examine the associations between behavioral and emotional characteristics and middle school student achievement across different grades based on a growth modeling approach. Using a total of 1,874 students, target predictor variables (i.e., attention, aggressiveness, behavioral control, social withdrawal, depression, self-esteem) and dependent variables (i.e., Korean language arts, mathematics) were extracted from a national and longitudinal data set, and four predictor models were formulated to examine the influence of behavioral/emotional characteristics on student growth trajectories. Results showed that (a) students' initial performance at seventh grade did not predict their over-time growth; and (b) self-esteem and behavioral control variables impacted on the seventh graders' achievement as well as their growth from the seventh to ninth grade. Based on the findings, practical implications and future research are discussed.
Optimal tube voltage for abdominal enhanced CT in children: a self-controlled study
Authors: Sun Jihang , Zhang Qifeng , Zhou Zuofu , Jia Chenguang , Yang Wei , Li Haoyan , Peng Yun
Published: June 2019

Background

The use of weight-adapted pediatric computed tomography (CT) tube voltage protocols has been suggested, but a consensus standard has not been established and clinical available studies are not sufficient.

Purpose

To determine the best tube voltage for low dose abdominal CT imaging in children.

Material and Methods

Eighty-seven cases who needed three CT exams in a 1–3-month interval between scans were enrolled (mean age = 4.69 ± 3.20 years). The three scans were performed with three different tube voltages at 80 kV, 100 kV, and 120 kV, keeping the same radiation dose and same contrast injection protocol. Patients were divided into five groups for analysis based on their body weight. The subjective image quality of the three exams were evaluated using a 4-point scale (4 being the best) for image noise and image quality. The objective evaluation in terms of CT values and standard deviation in aorta, liver, spleen, pancreas, and kidney were measured to calculate the degree of enhancement and contrast-to-noise ratio (CNR) of organs. One-way ANOVA was used to compare the subjective and objective image quality with respect to different tube voltages and different patient weights.

Result

The 80-kV tube voltage provided the highest overall enhancement and CNR for the entire patient population and the best objective image quality for the 6.1–28.0 kg subgroup.

Conclusion

Patient weight-dependent tube voltage selection maximizes image quality for abdominal enhanced CT in children. The optimal tube voltage for children with weight <28 kg is 80 kV; higher voltages should be selected for children weighing 28.1–50.0 kg.
What to Where: The Right Attention Set for the Wrong Location

One of the strongest predictors of whether or not an object in our environment captures our attention is the similarity between that object’s features and those we have prioritized—our attention set. For example, in inattentional blindness tasks, people are more likely to notice an unexpected white shape when tracking white objects than when tracking black objects. These attention sets are assumed to operate globally, enhancing perception of the critical feature across the entire visual field. We tested this assumption in four inattentional blindness experiments. Although observers were more likely to notice a white unexpected object when tracking white shapes, the effect of the participant’s attention set was substantially smaller or absent for objects appearing beyond the attended region. This result challenges the idea that attention sets help guide attention to relevant objects appearing in otherwise unattended regions.
The union default solution to declining union membership
Authors: Gall Gregor , Harcourt Mark
Published: June 2019

The continued stasis in the now much reduced aggregate levels of union membership in Britain and elsewhere has such portent for widening inequalities in wealth and power under the neo-liberal variant of late capitalism that a union default requires introduction. In all countries around the world, the de facto system is a non-union default. Under a union default, all workers would be defaulted into membership of the appropriate union. This is not a proposal for compulsory membership, a contravention of individual liberty nor the return of the closed shop by the backdoor because workers will have the right to opt out of membership. The right to be the appropriate default union to which workers would be defaulted into in any workplace would be gained by the union passing a low minimum support threshold. This would bring with it the right to bargain over pay and conditions.
Artificial Neural Networks for Predicting the Response of Unbonded Concrete Overlays in a Faulting Prediction Model

Published: June 2019

Transverse joint faulting is a common distress in unbonded concrete overlays (UBOLs). However, the current faulting model in Pavement mechanistic-empirical (ME) is not suitable for accurately predicting the response of UBOLs. Therefore, to develop a more accurate faulting prediction model for UBOLs, the first step was to develop a predictive model that would be able to predict the response (deflections) of these structures. To account for the conditions unique to UBOLs, a computational model was developed using the pavement-specific finite element program ISLAB, to predict the response of these structures. The model was validated using falling weight deflectometer (FWD) data from existing field sections at the Minnesota Road Research Facility (MnROAD) as well as sections in Michigan. A factorial design was performed using ISLAB to efficiently populate a database of fictitious UBOLs and their responses. The database was then used to develop predictive models, based on artificial neural networks (ANNs), to rapidly estimate the structural response of UBOLs to environmental and traffic loads. The structural response can be related to damage through the differential energy concept. Future work will include implementation of the ANNs developed in this study into a faulting prediction model for designing UBOLs.

Published: June 2019

Due to changes in the working temperature in a shearer transmission system, it is easy to cause the transmission gear to work abnormally. In this paper, the first gear pair in a cutting transmission system of a permanent magnet semi-direct drive shearer was taken as the research object. The coupling effect of time-varying meshing stiffness, meshing damping, bearing clearance and gear backlash under thermal deformation were fully considered. Then, a three degree of freedom nonlinear dynamic model of the gear pair was established, and a dimensionless analysis was performed. Finally, the Runge-Kutta method was used in the numerical calculations. The motion characteristics of the system were analysed through the gear’s bifurcation diagram of the temperature at different frequencies and the bifurcation diagram of the frequency at different temperatures. The meshing state was analysed at different frequencies and temperatures. For the chaotic motion generated in the system, a periodic resonance excitation was applied to control unstable motion. This study has revealed various specific effects of the temperature on the dynamic characteristics of the system. In addition, the periodic excitation method can effectively control the nonlinear motion in the system and realise the control of the chaos under the temperature effect.
Sliding-mode control of automotive selective catalytic reduction systems with state estimation
Authors: Ma Yao , Wang Junmin
Published: June 2019

A sliding-mode controller for an automotive selective catalytic reduction system is designed to drive its ammonia surface coverage ratio to the target level. The proposed controller only requires NOx, temperature and air flow sensor measurement installed on most mass production vehicles. Selective catalytic reduction systems have been widely equipped on diesel-powered ground vehicles to remove excessive NOx emissions. The tradeoff between NOx removal efficiency and ammonia slip poses a control challenge on regulating the ammonia surface coverage ratio to a proper level in the presence of disturbance. In this study, a sliding-mode controller is designed with explicit consideration of measurement noise and actuator saturation. The finite time convergence of tracking error is proved by a Lyapunov approach. For implementation purpose, an observer of ammonia surface coverage ratio and ammonia slip is also designed to provide states feedback and fault diagnostic information. The closed-loop controller performance is evaluated under an urban driving scenario based on an experimentally validated model. Results demonstrate the robust tracking performance and estimation accuracy against bounded uncertainties. The overall NOx efficiency is maintained with an acceptable ammonia slip level during the transient test cycle FTP75.

Published: June 2019

The main aim of this article is to present the experimental data of the operating parameters and emissions obtained in a small gas turbine equipped with a variable area nozzle system. The variable area nozzle is proposed as a means of improving turbine efficiency, which has been a popular trend in recent development of gas turbine engines. Based on turbine vane twisting, the proposed variable area nozzle system was developed and implemented in GTM-120 small gas turbine. The concept was experimentally investigated on the engine test bench and engine working parameters were accurately measured. Experimental research shows that significant improvement of engine specific fuel consumption (up to 4%) and specific thrust (up to 5%) has been achieved. Additionally, reduction in CO emissions (up to 64%), NO emissions (up to 7%) and NO2 emissions (up to 53%) has been noted. Experimental research results were compared with analytical engine model showing moderate, qualitative agreement between the experimental data and model outputs. Main advantages of variable area nozzle system and design challenges of the proposed concept are discussed in the article summary.
The Power of Humanitarian Narratives: A Domestic Coalition Theory of Justifications for Military Action
Authors: Maxey Sarah
Published: June 2019

Conventional wisdom assumes the best way to mobilize public support for military action is through the lens of national security. Humanitarian justifications provide a helpful substitute when US interests are not at stake, but are less reliable. However, US presidents have provided humanitarian explanations for every military intervention of the post-Cold War period. What, if any, power do humanitarian justifications have in security-driven interventions? The article answers this question by developing a domestic coalition framework that evaluates justifications in terms of whose support matters most in the build-up to intervention. Survey experiments demonstrate that humanitarian narratives are necessary to build the largest possible coalition of support. However, presidents risk backlash if they stretch humanitarian claims too far. Data from thirteen waves of Chicago Council surveys and an original dataset of justifications for US interventions confirm that humanitarian justifications are a common and politically relevant tool. The findings challenge both the folk realist expectation that the public responds primarily to threats to its own security and the constructivist tendency to limit the power of humanitarian justifications to cases of humanitarian intervention. Instead, humanitarian justifications are equally, if not more, important than security explanations for mobilizing domestic support, even in security-driven interventions.
Religious and Spiritual Values Conflicts in Queer Partnerships: Implications for Couples and Family Counselors
Authors: Killian Thomas , Peters Harvey C. , Brottem Lainey J.
Published: June 2019

In providing couples and family counseling to sexual/affectional and gender variant minorities (i.e., queer persons), couples and family counselors (CFCs) need to recognize that religious and spiritual identity can be salient topics. While many queer persons embrace an irreligious identity, some queer individuals embrace varied degrees of religious/spiritual identification. In a partnership, an intrarelational conflict could result when the partners do not adhere to a similar level of religiosity or spirituality. CFCs must be prepared to accept the possibility of such conflict, allow for the embrace of religious identification, and offer counseling practices that will bridge that relational gap.
Radial basis function neural network chaos control of a piezomagnetoelastic energy harvesting system
Authors: Dehghani R. , Khanlo H. M.
Published: June 2019

In this paper, an adaptive chaos control is proposed for a typical vibratory piezomagnetoelastic energy harvesting system to return the chaotic behavior to a periodic one. Piezomagnetoelastic energy harvesting systems show chaotic behaviors in spite of harmonic input. Although, the chaotic behavior of the system gives higher output voltage than the periodic motion, it is preferred to the output voltage as this is periodic for charging a battery or a capacitor efﬁciently. Therefore, the chaos control is important in this system. The physical model is composed of the upper and lower piezoelectric layers on a cantilever taper beam, one attached tip magnet, and two external magnets (EM). Position of the EM is controlled by inputs. Firstly, chaotic and periodic regions are detected by utilizing the bifurcation diagrams, phase plan portrait, and Poincaré maps. Then an adaptive controller is proposed for controlling of the chaotic behaviors in the presence of uncertainty due to magnetic forces. The control law is derived based on the inverse dynamic method and the uncertainty elements of the controller are estimated using radial basis function (RBF) network. The weights of the RBF network are obtained using an adaptation law. The adaptation laws are derived based on Lyapunov stability theory and a projection operator. The distance of the tip magnet and the EM as well as the gap distance of two EM are used to control the chaotic behavior. Simulation results show that the proposed controller can return the chaotic motion to a periodic one in spite of the uncertainties in the magnetic forces.
