Hepatic progenitor cell (HPC) marker-positive hepatocellular carcinomas (HCCs) have recently been extensively analyzed, and their prognosis has been reported as poor compared to HPC marker-negative HCCs. However, previous studies have analyzed the existence of HPC marker-positive cancer cells only in primary lesions, as well as the recurrence rate and prognosis of such tumors. Here, we are the first to report the behavior of HPC marker-positive cancer cells during vascular invasion and metastasis of an HCC. We concurrently analyzed EpCAM- and/or NCAM-expressing cancer cells in the primary, vascular invasion, and metastatic lesions of an HCC. An HCC which includes EpCAM- and/or NCAM-expressing cancer cells has not been previously reported. EpCAM- and/or NCAM-positive cancer cells invaded the vessels and formed heterogeneous populations of these HPC marker-positive cancer cells with HPC marker-negative cancer cells. The frequency of HPC marker-positive cancer colonies and cells in vessels was higher than that in the primary HCC. In the metastatic lesions, EpCAM-positive cancer cells were more frequently detected than NCAM-positive cancer cells, indicating that EpCAM may be more important than NCAM for cancer cell settlement in the metastatic lesions. Furthermore, bigger metastatic tumors tended to include HPC marker-positive cancer cells, suggesting that HPC marker-positive cancer cells have a growth advantage in the metastatic lesions. These results showed that HPC marker-positive cancer cells would be important for vascular invasion and metastasis and suggested that HPC marker-positive cancer cells are an important target in HCC treatment.

Published: March 2019

A 49-year-old man was referred to our hospital for an abnormality of the hepatobiliary enzyme. The patient was diagnosed with primary sclerosing cholangitis 9 years ago, and he had a biliary stent with a string placed as an inside stent. We attempted to remove the stent 6 months later, but the string was cut off, so the stent could not be removed. Removal was attempted again, but the patient cancelled the outpatient appointments. During the examination performed at the present visit, we discovered that the biliary stent had migrated into the bile duct, and a stone had formed around the stent. We attempted to remove the stent-stone complex by endoscopic retrograde cholangiopancreatography, but it was difficult; thus, we decided to implant a new biliary stent and remove the other stent later. When we performed endoscopic retrograde cholangiopancreatography again 2 days later, the bile duct axis was linearized thanks to the additional stent, enabling us to grab the migrated stent with stent-stone complex using grasping forceps and to successfully pull it out. By implanting an additional plastic stent temporarily, we were able to straighten the biliary axis and endoscopically remove the biliary stent that migrated and caused the development of stent-stone complex in a 2-staged approach.
Improving the Diagnosis of Culprit Left Circumflex Occlusion With Acute Myocardial Infarction in Patients With a Nondiagnostic 12‐Lead ECG at Presentation: A Retrospective Cohort Study
Authors: Daly Michael J. , Scott Peter J. , Harbinson Mark T. , Adgey Jennifer A.
Published: March 2019

Background

Left circumflex culprit is often missed by the standard 12‐lead
ECG
. Extended lead systems (body surface potential map [
BSPM
]) should improve the diagnosis of culprit left circumflex stenosis with myocardial infarction.

Methods and Results

Retrospective analysis of a hospital research registry (August 2000–August 2010) comprising consecutive patients with (1) ischemic‐type chest pain at rest; (2) 12‐lead
ECG
and 80‐lead
BSPM
at first medical contact; and (3) cardiac troponin‐T 12 hours after symptom onset and/or creatine kinase MB fraction, were undertaken. Enrolled in the cohort were patients with culprit left circumflex stenosis (thrombolysis in myocardial infarction flow grade 0/1) at angiography. Acute myocardial infarction
AMI
was defined as cardiac troponin‐T ≥0.1 μg/L and/or creatine kinase MB fraction >2 upper limits of normal. Enrolled were 482 patients: 168 had exclusion criteria. Of the remaining 314 (age 64±11 years; 62% male), 254 (81%) had
AMI
: of these, 231 had
BSPM STE
—sensitivity 0.91, specificity 0.72, positive predictive value 0.93, negative predictive value 0.65, and c‐statistic 0.803 for
AMI
(
P
<0.001). Of those with
BSPM STE
and
AMI
(n=231),
STE
was most frequently detected in the posterior (n=111, 48%), lateral (n=53, 23%), inferior (n=39, 17%), and right ventricular (n=21, 9%) territories.

Conclusions

Among patients with 12‐lead
ECG
non‐ST‐segment–elevation myocardial infarction and culprit left circumflex stenosis, initial
BSPM
identifies ST‐segment elevation beyond the territory of the 12‐lead
ECG
. Greater use of the
BSPM
may result in earlier identification of
AMI
, which may lead to more rapid reperfusion.
A simple solution for accurate measuring of long and contorted ovipositors in pinned specimens of Hymenoptera
Authors: AGUIAR ALEXANDRE P.
Published: March 2019

Practical problems exist when measuring long ovipositors that are strongly curved or twisted. A simple, effective and practically costless method is proposed to straighten curved ovipositors of pinned, dry specimens of Hymenoptera. The method holds the ovipositor, but not its sheaths, with a piece of adhesive tape fixed to a pin. A separate pin is then used as a lever to move the pin with the tape, pull and straighten the ovipositor, and hold the entire contraption in position. The method is tested with species of Stephanidae, Ichneumonidae and Gasteruptiidae, and defended as the best choice in relation to conventional as well as other unpublished possibilities, all summarized.

Description of a new Geodipsas snake from northern Madagascar (Squamata: Colubridae)
Authors: MERCURIO VINCENZO , ANDREONE FRANCO
Published: March 2019

We describe a new species of the colubrid snake genus Geodipsas from the rainforests of the Anjanaharibe-Sud and Tsaratanana massifs, northern Madagascar. Geodipsas fatsibe n. sp. differs from the other described species of the genus in the following characteristics: 21 rows of dorsal scales at midbody, high number of ventral (198) scales and by the presence of very large hooked spines on the hemipenis. Geodipsas fatsibe is most similar to Geodipsas infralineata. Most likely they are sister species, with a vicariant northern vs. central southern distribution.
Description of two new species of Hetereleotris (Gobiidae) from the south Pacific, with a revised key to species and synonymization of the genus Pascua with Hetereleotris
Authors: HOESE DOUGLASS F. , LARSON HELEN K.
Published: March 2019

Two new species of the genus Hetereleotris are described from the south Pacific. One species is known only from reefs off southeastern Australia and the second from Rapa and Pitcairn islands. Both species are close to a species recently described from Easter Island in the genus Pascua. The Easter Island species is redescribed herein. Previously only one species of the genus was reported from the Pacific. All of the species described here share a number of characteristics suggesting that they form a monophyletic group, including: the flattened and elongate urogenital papilla of the males, modified basicaudal scales, posterior nostril a simple pore or with only a slightly elevated margin anteriorly, two papillae just behind the mental frenum and the reduced transverse papilla pattern.
A new species of Jenynsia (Cyprinodontiformes: Anablepidae) from northwestern Argentina and its phylogenetic relationships
Authors: AGUILERA GASTÓN , MIRANDE JUAN MARCOS
Published: March 2019

Jenynsia tucumana new species is described from the upper Río Salí basin, province of Tucumán, northwestern Argentina. The new species is diagnosed by the possession of a row of dark markings ranging from dots to small vertical stripes from the tip of adpressed pectoral fin to the posterior margin of the hypural. Also, the new species has a mandibular canal pore W and a symmetrical fifth anal-fin ray in adult males; whereas the females lack a urogenital swelling. According to a phylogenetic reanalysis of the genus, the new species is sister to most species of the subgenus Jenynsia, except for J. onca and possibly J. sanctaecatarinae.

A taxonomic review of the tribe Melaenini (sensu novo), this paper includes a classification, keys at all taxonomic levels, descriptions (tribe to species), re-rankings, and new synonymy. In total, two genera and 22 species (three of which are new) are treated. Arrangement of taxa is in the following sequence, with junior synonyms and type localities of new species in parentheses, following name of the taxon. The Eastern Hemisphere genus Melaenus Dejean, 1831 includes M. piger (Fabricius, 1801), and M. elegans Dejean, 1831 (with M. elongatus Chaudoir, 1843, as a new junior synonym), which exhibits marked dimorphism in East Africa. The genus Cymbionotum Baudi di Selve, 1864 includes 20 species, arranged in two subgenera, as follows. The Western Hemisphere Procoscinia, n. subg. (type species, C. fernandezi, n. sp. [Zambrano, Bolivar, Colombia]), includes the type species and C. negrei Perrault, 1994. The Eastern Hemisphere subgenus Cymbionotum (sensu stricto) includes 18 species in three species groups, and three superspecies. The basale species group includes two species: C. semirubricum (Reitter, 1914) (new junior synonyms Graniger aethiopicus Alluaud, 1923, C. minax Andrewes, 1935, and C. a. airense Basilewsky, 1950), and C. basale (Dejean, 1831). The semelederi species group includes three species: C. semelederi (Chaudoir, 1851) (new junior synonyms, Coscinia funerula Fairmaire, 1885, Cymbionotum luniferum Andrewes 1935, and Graniger houskai Jedli…ka, 1951), C. striatum Reitter, 1894, and C. mandli Jedli…ka, 1963.
Anapisa monotonia Kiriakoff, 1963 – a junior synonym of Anapisa holobrunnea (Talbot, 1932), with new records of Arctiinae (Lepidoptera: Erebidae) from Ghana
Authors: PRZYBYŁOWICZ ŁUKASZ , BĄKOWSKI MAREK
Published: March 2019

Arctiinae (Lepidoptera: Erebidae) of the African continent are relatively poor studied compared to other tropical areas. Their distribution is almost completely unknown in many countries or it is based on old, unverified literature data, although some useful information can be extracted from the online database “Afromoths” (De Prins & De Prins 2011). Modern national or regional checklists covering all of the Arctiinae exist for Lesotho (Kopij 2005), Nigeria (Medler 1980), Southern Africa (Vári et al. 2002) and Madagascar (Viette 1990). Generally, revisionary works treating the whole continent concern only Arctiini (Goodger & Watson 1995) and Syntomini: Thyretina (Kiriakoff 1960, Przybyłowicz 2009). Currently more than 40 species of Arctiini (Goodger & Watson 1995) and 15 species of Thyretina (Syntomini) (Przybyłowicz 2009) are recorded from Ghana.

Taxonomic notes, new species and identification key to the New World species of Toxophora Meigen (Diptera, Bombyliidae, Toxophorinae)
Authors: CUNHA ANDRÉ M. , LAMAS CARLOS JOSÉ E. , COURI MÁRCIA S.
Published: March 2019

Two new species of Toxophora Meigen are described and illustrated—T. paulistana sp. nov. (Neotropical) and T. azteca sp. nov. (Nearctic and Neotropical). An identification key to the New World species is also presented. Morphological differences between populations of T. aurea Macquart (1848) are recorded, illustrated and added to the key. The new species are easily recognized by: scape with long, yellow scales laterally; presence of yellow scales on mesonotum margins; posterior margin of mesonotum with a pre-scutellar pair of setae; and yellow scales forming thin bands on posterior margins of abdominal tergites in T. paulistana sp. nov., and scape entirely covered with long dark-brown scales and yellow scales forming a broad, longitudinal stripe on center of abdominal tergites III-VII in T. azteca sp. nov.
Georgeiella, a new name for the louse genus Hopkinsiella Clay and Meinertzhagen, 1939 (Phthiraptera, Philopteridae), junior homonym of Hopkinsiella Baba, 1938 (Opisthobranchia, Goniodorididae)
Authors: VALIM MICHEL P. , PALMA RICARDO L.
Published: March 2019

Clay and Meinertzhagen (1939) described the genus Hopkinsiella to accommodate one new species of louse found on the Kikuyu white-headed wood-hoopoe—Phoeniculus bollei jacksoni (Sharpe, 1890)—of the bird family Phoeniculidae. Tendeiro (1957) described a second species of Hopkinsiella, parasitic on a bird species of the same family. Subsequently, Tendeiro (1961) described one more species and reviewed all the species included in the genus. We have found that the name Hopkinsiella Clay & Meinertzhagen, 1939 is preoccupied by Hopkinsiella Baba, 1938, a genus of nudibranchs – marine gastropod molluscs of the order Opisthobranchia (Baba, 1938).

Prorops Waterston 1923 can be easily distinguished from the other genera of Sclerodermini (Bethylidae: Epyrinae) mainly by having frontal process of head well-developed; antenna twelve segmented; median, basal, and anal veins absent (Evans 1978; Terayama 2006).
Phylogenetic analysis of Western Atlantic Bathygobius (Teleostei: Gobiidae)
Authors: TORNABENE LUKE , PEZOLD FRANK
Published: March 2019

The phylogenetic relationships of the Western Atlantic species of Bathygobius are inferred from DNA sequence data from two mitochondrial genes (cytochrome b, cytochrome c oxidase-I) and one nuclear gene (Recombination Activating Gene I). The phylogeny inferred from the concatenated dataset of the three genes uncovered the following major findings: (i) the Western Atlantic species of Bathygobius as a whole are not monophyletic; (ii) a well-supported monophyletic group containing B. soporator, B. lacertus and the Eastern Pacific B. andrei was recovered (termed the B. soporator group); (iii) a well-supported monophyletic group was recovered that contains B. curacao, the Eastern Pacific B. ramosus and B. lineatus, and B. antilliensis (termed the B. antilliensis group); (iv) the relationships between the several lineages of new world Bathygobius and some species of old world Bathygobius could not be resolved, and monophyly of a clade of all new world species could not be determined. The evolutionary history of the Western Atlantic species involves periods of diversification that occurred both before and after the closure of the Isthmus of Panama.
Species of the subgenus Minuspio (Polychaeta: Spionidae: Prionospio) from the southern coast of Turkey (Levantine Sea, eastern Mediterranean), with the description of two new species
Authors: DAGLI ERTAN , ÇINAR MELIH ERTAN
Published: March 2019

Three species belonging to the subgenus Minuspio are described from the southern coast of Turkey. Prionospio (Minuspio) anatolica sp. nov., and Prionospio (Minuspio) maciolekae sp. nov. are new to science and P. (M.) pulchra is a new report for the marine fauna of the Levantine and Black Sea coasts of Turkey. Prionospio (M.) anatolica sp. nov., differs from all other Prionospio (M.) species by the shape of the prostomium, branchiae, and the absence of eyes. This species has 7 pairs of long, apinnate branchiae on chaetigers 2 to 8. Prionospio (M.) maciolekae sp. nov., differs from other Prionospio (M.) species in having short, densely ciliated branchiae and distinct dorsal crests on chaetigers 10–28. The examination of older materials deposited at the Museum of Ege University (ESFM) revealed that Prionospio (M.) pulchra, an alien invasive species, also occurred in the Aegean and Black Seas since 2000. In the Mediterranean, this species seems to be first noticed from the Italian waters (Tyrrhenian Sea, Lago di Sabaudia) and misidentified as Prionospio cirrifera. These species were encountered on a variety of biotopes in the region. In addition, two specimens of P. (M.) multibranchiata collected near the type locality (Bazan Bay, Pacific coast of Canada) were examined and a redescription of this species was made. The morphology, ecology and distribution of these species are given together with a taxonomic key to all valid species of the subgenus Minuspio.

Three new species of the fangblenny genus Meiacanthus from Indonesia, with color photographs and comments on other species (Teleostei: Blenniidae: Nemophini)
Authors: SMITH-VANIZ William F. , ALLEN GERALD R.
Published: March 2019

Three new species of fangblennies are described from Indonesia. Meiacanthus abruptus is described based on two specimens, 31.4–36.6 mm SL, from Komodo Island and color photographs of others from Bali. The combination of a white or yellow body color and a single dark mid-lateral stripe that is bluntly rounded at its terminus on the caudal-fin base distinguishes it from other single striped species. This new species closely resembles the allopatric M. vicinus, which has the mid-lateral stripe extending farther onto the caudal fin and tapering to a point. Meiacanthus erdmanni is described from the only known specimen, 35.8 mm SL, photographed and collected in 65–70 m in Cenderawasih Bay, western New Guinea. One of the deepest known species of Meiacanthus, it has two dark mid-lateral stripes and differs from other doublestriped species in having a series of dark blotches on the base of the dorsal fin and only 24 segmented dorsal-fin rays. Meiacanthus cyanopterus, another deep-water species, is described from seven specimens, 19.8–45.3 mm SL, collected in 40–65 m at three sites in Alor Strait. In life this species has a dorsal fin with a blue-violet stripe bordered above by a wide black stripe. An identification key is provided for all the striped species of Meiacanthus, including at least one additional undescribed species previously confused with M. abditus. Color photographs of other Meiacanthus species and some new distributional records are also given.
Redescription of the tadpole of Macrogenioglottus alipioi (Anura: Cycloramphidae), a rare and endemic species of the Brazilian Atlantic Forest

Published: March 2019

The monotypic genus Macrogenioglottus Carvalho include the species M. alipioi, described from Ilhéus, state of Bahia, Brazil (Carvalho, 1946). Its distribution comprises the Atlantic Forest domain (Ab’Sáber, 1967) in the northeastern and southeastern Brazil (Tiburcio et al., 2008). Abravaya and Jackson (1978) described briefly the tadpole of this species. Therefore, a more detailed description of the larval morphology is needed.

Chitons (Mollusca: Polyplacophora) of Hainan Island and vicinity, South China Sea
Authors: SIRENKO BORIS I. , ZHANG JUNLONG
Published: March 2019

The chiton fauna of Hainan Island and its vicinity is poorly known. In this contribution, we present the first comprehensive account of the living chitons from this area. The present compilation is based on the study of historical collections housed in Qingdao (China), Saint Petersburg (Russia), new samples from Hainan Island and data from literature. Six species (Rhyssoplax venusta, Lucilina lamellosa, L. tenuicostata, L. tilbrooki, Onithochiton stracki and Acanthochitona intermedia) are reported for the first time from this area. Three species (Acanthochitona achates, A. britayevi and A. lanae) are re-identified on the basis of descriptions, drawings and photographs in old articles. We now know a total of 30 species (belonging to 18 genera in seven families) from the vicinity of Hainan Island. While examining material of Lucilina lamellosa, we found two forms: L. lamellosa forma typica and the new form L. lamellosa forma costata. Both forms differ from each other in the structure of the tegmentum of the pleural areas.
A catalogue of Eudóxia M. Froehlich's collection of planarians (Platyhelminthes) with emphasis on type specimens on histological slides
Authors: DE OLIVEIRA KARINE GOBETTI , CARBAYO FERNANDO
Published: March 2019

Leading taxonomist Prof. Eudóxia Maria Froehlich (1929*–2015†) kept an uncatalogued personal collection of a large set of histological glass slides of land planarians. Many of these slides carry insufficient written information for identification purposes. 2287 slides of her collection were examined under the microscope and compared with relevant literature. We found 1633 slides bearing type material of a total of 119 nominal species, mostly collected in the Neotropical region. Identification of 148 slides (belonging to 16 species) as type material is suspected but not confirmed. Type material represents 110 triclad species. There is also type material of two Polycladida, two Rhabdocoela, three Proseriata, one Prolecitophora, and one Acoelomorpha species. The 119 nominal species were described by Ernest Marcus, Eveline du Bois Reymond-Marcus, Diva Diniz Corrêa, Cláudio Gilberto Froehlich, and Eudóxia Maria Froehlich. While keeping the slides in their original location in cupboards, the catalogue provides a quick means of retrieving desired slides. Slides were deposited in the Museu de Zoologia da Universidade de São Paulo.

Comparative morphology of female gonapophyses IX in Delphacidae (Hemiptera: Auchenorrhyncha: Fulgoromorpha) with key to tribes
Authors: WALLNER ADAM M. , BARTLETT CHARLES R.
Published: March 2019

Diagnoses for delphacid species rely on male genitalia, with female structures rarely considered. In this study, we examined gonapophyses IX from 36 exemplar species, representing all 14 tribes of Delphacidae. From these 36 species, we found 53 potential synapomorphies. We present a key to delphacid tribes that integrates gonapophyses IX features. We hypothesize that the basal delphacids, the Asiracinae, have teeth concentrated at the apex to make short incisions into soft plant tissue. In Vizcayinae, these teeth are greatly reduced, extending past the apex, and may function to pierce host tissue. In Plesiodelphacinae, these teeth are increased in size and number, potentially to function as a saw. In Kelisiinae, teeth size is reduced, while teeth frequency is increased subapically. Finally, in the Stenocraninae and Delphacinae, the most derived lineages, an increase in tooth size and shape may have developed to cut into graminoid hosts with high concentrations of silicate.
Two new apseudomorphan species (Crustacea: Tanaidacea: Metapseudidae) from Mo‘orea Island (Society Islands, French Polynesia) with taxonomic keys
Authors: MORALES-NÚÑEZ ANDRÉS G. , HEARD RICHARD W. , BIRD GRAHAM J.
Published: March 2019

Previous information on the taxonomy and distribution of the crustacean order Tanaidacea occurring within the widely-dispersed Polynesian Archipelago has been limited to four nominal species, Apseudes rikiteanus Nobili, Apseudes seurati Nobili, Zeuxo seurati (Nobili) and Tanzanapseudes polynesiensis Müller. Based on specimens collected between 2009 and 2011 from coastal waters of Mo‘orea Island (Society Islands, French Polynesia), two new metapseudid tanaidaceans, Apseudomorpha drummi and Cryptapseudes mamua, are described. Keys to the identification of species currently placed within the genera Apseudomorpha Guţu and Cryptapseudes Băcescu are provided.
Predictability of North Atlantic Sea Surface Temperature and Upper-Ocean Heat Content
Authors: Buckley Martha W. , DelSole Tim , Lozier M. Susan , Li Laifang
Published: March 2019

Understanding the extent to which Atlantic sea surface temperatures (SSTs) are predictable is important due to the strong climate impacts of Atlantic SST on Atlantic hurricanes and temperature and precipitation over adjacent landmasses. However, models differ substantially on the degree of predictability of Atlantic SST and upper-ocean heat content (UOHC). In this work, a lower bound on predictability time scales for SST and UOHC in the North Atlantic is estimated purely from gridded ocean observations using a measure of the decorrelation time scale based on the local autocorrelation. Decorrelation time scales for both wintertime SST and UOHC are longest in the subpolar gyre, with maximum time scales of about 4–6 years. Wintertime SST and UOHC generally have similar decorrelation time scales, except in regions with very deep mixed layers, such as the Labrador Sea, where time scales for UOHC are much larger. Spatial variations in the wintertime climatological mixed layer depth explain 51%–73% (range for three datasets analyzed) of the regional variations in decorrelation time scales for UOHC and 26%–40% (range for three datasets analyzed) of the regional variations in decorrelation time scales for wintertime SST in the extratropical North Atlantic. These results suggest that to leading order decorrelation time scales for UOHC are determined by the thermal memory of the ocean.

Published: March 2019

Tornadoes that occur at night pose particularly dangerous societal risks, and these risks are amplified across the southeastern United States. The purpose of this study is to highlight some of the characteristics distinguishing the convective environment accompanying these events. This is accomplished by building upon previous research that assesses the predictive power of meteorological parameters. In particular, this study uses the Statistical Severe Convective Risk Assessment Model (SSCRAM) to determine how well convective parameters explain tornado potential across the Southeast during the months of November–May and during the 0300–1200 UTC (nocturnal) time frame. This study compares conditional tornado probabilities across the Southeast during November–May nocturnal hours to those probabilities for all other November–May environments across the contiguous United States. This study shows that effective bulk shear, effective storm-relative helicity, and effective-layer significant tornado parameter yield the strongest predictability for the November–May nocturnal Southeast regime among investigated parameters. This study demonstrates that November–May southeastern U.S. nocturnal predictability is generally similar to that within other regimes across the contiguous United States. However, selected ranges of multiple parameters are associated with slightly better predictability for the nocturnal Southeast regime. Additionally, this study assesses conditional November–May nocturnal tornado probabilities across a coastal domain embedded within the Southeast. Nocturnal coastal tornado predictability is shown to generally be lower than the other regimes. All of the differences highlight several forecast challenges, which this study analyzes in detail.
Deconstructing Generations: Concluding Remarks
Authors: della Porta Donatella
Published: March 2019

This concluding article of the special issues summarizes the empirical results presented in the previous contributions within a comparative perspective, with particular attention to locate them within previous research on youth mobilizations. From the theoretical point of view, the articles, based on the research conducted in the context of the CRY_OUT project, have tried to bridge some concepts in youth studies and social movement studies. Using the concept of generations in a critical way, we have in fact aimed at deconstructing it by looking at the meaning given to generations by movement activists, to their self-perception in terms of generational identification, as well as their taste in terms of contentious frames and practices. Empirically, we have addressed, in particular, the mobilization of Millennials in anti-austerity protests on issues such as labor and also women’s and gender rights, antiracism, environmental protests, and alternative cultural and/or recreational initiatives. Focusing on Europe, we have chosen some paradigmatic cases of protests in the United Kingdom, Southern European Italy and Spain, and Eastern European Poland. In light of the theoretical questions presented in the introduction, this article addresses, in turn, the conceptions of generations in movements, the self-assessment by Millennials, as well as some characteristics of their mobilizations in terms of organizational structures, repertories of action, and collective framing.
Do Incorporation Policies Matter? Immigrants’ Identity and Relationships With the Receiving Society
Authors: Breton Charles
Published: March 2019

Are multiculturalism policies associated with a rejection of the receiving society’s identity by immigrants? Is there a policy arrangement that makes identification with the receiving society more likely? This article addresses head-on whether there is a trade-off between ethnic identification and relationships with the host society and whether this trade-off is associated with certain policy regimes. Looking at immigrants in 10 Western democracies, the results show that despite the fact that inclusive policies decrease identification with the majority, they do so while being associated with integrationist orientations on issues such as language choice and cultural traditions. Immigrants in these countries value relationships with both their ethnic group and the majority to a greater extent. In countries with inclusive policies, ethnic identification is also associated with commitment to the receiving society and, contrary to more restrictive regimes, does not lead to greater perceived discrimination. These findings are robust to additional models looking at Muslim immigrants.
Presidential Term Limit Contravention: Abolish, Extend, Fail, or Respect?
Authors: McKie Kristin
Published: March 2019

Since presidential term limits were (re)adopted by many states during the third wave of democratization, 221 presidents across Latin America, Africa, the Middle East, and Asia have reached the end of their term(s) in office. Of these, 30% have attempted to contravene term limits, resulting in either full abolition, one-term extensions, or failure. What explains these divergent trajectories? I argue that trends in electoral competition over time best predict term limit outcomes, with noncompetitive elections permitting full abolition, less competitive elections allowing for one-term extensions, and competitive elections leading to failed bids. This is because electoral trends provide informational cues to the president’s co-partisan legislators and constitutional court judges (the actors who ultimately rule on constitutional term limit amendments) about the cost/benefit analysis that voting to uphold or repeal term limits would have on their own political survival. These findings suggest a linkage between political uncertainty and constitutional stability more generally.
Co-offending Group Composition and Violence: The Impact of Sex, Age, and Group Size on Co-offending Violence
Authors: Lantz Brendan
Published: March 2019

Co-offenders commit more violent offenses than solo offenders, in part due to collective behavior processes that exacerbate behavior in groups. But, different co-offenders likely experience these processes differently. Following this, this research examines the relationship between co-offending, group sex and age composition, and violence using National Incident–Based Reporting System (NIBRS) data. Results indicate that male groups are more likely to seriously injure victims, but that sex composition matters most in small groups; in larger groups, serious injury is likely regardless of sex composition. Furthermore, age is related to violence such that the presence of more young adult offenders is associated with increased likelihood of serious injury. Taken together, this research suggests the importance of considering group composition in the situational production of group violence.
Tailoring anisotropic thermal conductivity by varying filler particle organization in nickel-polydimethylsiloxane composites
Authors: Tsai Peiying J , Pal Souvik , Ghosh Suvojit , Puri Ishwar K
Published: March 2019

Anisotropic properties can be imparted to composite materials by arranging filler particles along specific directions inside the polymer matrix. These anisotropic patterns can be produced through dynamic field-assisted assembly of the filler particles during additive manufacturing. Using finite element analysis, we explore how chainlike arrangements of nickel particles embedded in a polydimethylsiloxane matrix modify bulk thermal conductivities in the axial and transverse directions. The axial conductivity increases up to nine times of the matrix conductivity with increasing filler volume fraction. While the axial conductivity decreases with increasing interparticle spacing, the transverse conductivity is uninfluenced. When particles within a chain are arranged in a zigzag pattern, increasing the interparticle zigzag angle decreases axial conductivity but increases transverse conductivity. As that angle increases to ∼55 º, the axial conductivity approaches a minimum, while the transverse conductivity approaches its maximum. An empirical model that includes effects of interparticle spacing and zigzag angle to predict the anisotropic thermal conductivity of a composite containing particle chains is presented. These results are relevant for the material design of particulate-reinforced polymer composites for advanced field-assisted additive manufacturing strategies.
Characterization and optimization of hybrid carbon–glass epoxy composites under combined loading
Authors: Infante V , Madeira JFA , Ruben Rui B , Moleiro F , de Freitas Sofia Teixeira
Published: March 2019

This work is intended to characterize the mechanical behavior of hybrid carbon–glass composite plates under combined loading of bending and torsion, and to determine the optimal ply fiber orientations to minimize the maximum out-of-plane displacement under such loading conditions. Hybrid composite plates were manufactured with 10 plies each and different stacking sequences using hand lay-up, with carbon fiber and glass fiber reinforcements in an epoxy matrix. Two experimental setups (involving two distinct boundary conditions) are here considered to test the composite plates, both simulating combined loading of bending and torsion. Numerical simulations of the experimental tests were performed in ABAQUS® and validated with the experimental data. Using the ply fiber orientations as design variables, the hybrid composite plates were then optimized using global and local optimization using direct search (GLODS). The objective function of minimization of the maximum out-of-plane displacement is carried out through an interactive cycle between GLODS and ABAQUS®. Specimens of three optimized laminates were also manufactured for experimental validation. The optimization process contributed to improve the performance of the hybrid composite plates in more than 30% when compared to some non-optimized plates.
When a child dies of heatstroke after a parent or caretaker unknowingly leaves the child in a car: How does it happen and is it a crime?
Authors: Diamond David M
Published: March 2019

It is commonly reported that in the course of a drive, a parent or caretaker loses awareness of the presence of a child in the back seat of the car. Upon arriving at the destination, the driver exits the car and unknowingly leaves the child in the car. This incomprehensible lapse of memory exposes forgotten children to hazards, including death from heatstroke. More than 400 children in the past 20 years have suffered from heatstroke after being unknowingly forgotten in cars. How can loving and attentive parents, with no evidence of substance abuse or an organic brain disorder, have a catastrophic lapse of memory that places a child’s welfare in jeopardy? This article addresses this question at multiple levels of analysis. First, it is concluded that the loss of awareness of a child in a car is a failure of a type of memory referred to as prospective memory (PM), that is, failure to remember to execute a plan in the future. Second, factors that increase the likelihood that PM will fail are identified. Third, research on the neurobiology of PM and PM-related memory failures are reviewed, including a discussion of how competition between brain structures contributes to a failure of PM. Finally, the issue of whether a failure of PM that results in harm to a child qualifies as a criminal offence is discussed. Overall, this neuropsychological perspective on how catastrophic memory errors occur should be of value to the scientific community, the public and law-enforcement agencies.
Understanding gender roles and practices in the household and on the farm: Implications for banana disease management innovation processes in Burundi
Authors: Iradukunda Francois , Bullock Renee , Rietveld Anne , van Schagen Boudy
Published: March 2019

Banana and plantain are one of the most important staple food crops and a significant source of income to smallholder farmers in the East African Great Lakes Region. Banana Xanthomonas Wilt (BXW) is a devastating bacterial disease that threatens smallholder production and livelihoods. We use a systems approach to describe how gender shapes roles and practices in the household, on the farm and in innovation processes. We draw on a case study in Burundi, where single disease stem removal (SDSR) has been introduced as a labour-saving package to reduce BXW incidence. Banana is grown by an estimated 90% of farmers, and BXW poses a critical threat to food security. We use qualitative data that include focus group discussions, interviews and transcripts from farmer learning group (FLG) discussions to describe gender norms, roles and practices and implications for awareness and uptake of SDSR in households. We identify gender patterns in innovation process, namely that men gain higher levels of access to information in FLGs than women and men are also primarily responsible for implementing SDSR. These patterns reflect gender-differentiated norms, roles and practices that are common in the household and in banana-based farming systems, thus demonstrating the ways that innovation processes perpetuate and reinforce common gender roles and practices. Women’s participation in FLGs, albeit lower than men, increases the potential of women to implement specific practices of the SDSR package. Systems approaches may be similarly used in different contexts where awareness and uptake of banana disease management packages, and other technical innovations, are not well understood. We found that gender norms, roles and practices significantly influence uptake of SDSR practices and warrant further investigation across the region, where smallholder uptake remains a pressing challenge to establish household food security.
