Artists’ Books Collection Development: Considerations for New Selectors and Collections
Authors: McLeland D. Courtenay
Published: November 2017

In the 2010 survey Taking Our Pulse: The OCLC Research Survey of Special Collections and Archives, artists’ books were the specific genre most often identified as a new collecting area within library special collections departments. For librarians at institutions without an artists’ books collection, beginning and sustaining the growth of a new collection can be an exciting and challenging opportunity to become acquainted with an additional area of specialized knowledge. Other librarians may be at institutions that possess a fledgling collection of artists’ books but find that collecting priorities or guidelines need to be determined prior to more active collection development efforts. In the fall of 2016, with the goal of identifying current and established collection models, the author visited librarians working with collections of artists’ books, distributed an online survey, and conducted a selective literature review. This article presents patterns identified in the survey results.
Concepções de professores sobre a sexualidade de alunos e a sua formação em educação inclusiva
Authors: Maia Ana Cláudia Bortolozzi , Vilaça Teresa
Published: November 2017

A educação sexual no contexto da escola é um processo importante que deve ser realizado pelos professores para todos os alunos. O objetivo desta revisão de literatura foi o de analisar as concepções de professores sobre a sexualidade de alunos com deficiência intelectual. Os artigos foram localizados em bases de dados na área da Educação e, a partir de critérios de exclusão, elegeram-se 83 artigos para análise de conteúdo. Encontraram-se as seguintes categorias: “educação sexual” (n=22); “aspectos da sexualidade de pessoas com deficiências” (n=28); “questões teóricas” (n=6); e “profissionais e familiares” (n=27). Esta última categoria foi desmembrada em: “concepções de professores” (n=7); “concepções de profissionais da saúde/cuidadores” (n=6), “concepções  e expectativas de adultos que convivem com pessoas com deficiência” (n=9); e “implementação de programas de educação sexual” (n=5). Nos sete artigos sobre as concepções dos professores, estes reconhecem que os alunos com deficiência intelectual são seres sexuais e têm manifestações sexuais na escola; compreendem essa sexualidade como “exagerada” e consideram que eles não entendem as informações recebidas. Os professores são favoráveis à educação sexual na escola. Mas, há aqueles que não consideram que esse seja o seu papel e outros que poderiam contribuir, apesar de necessitarem de preparação pessoal, formação continuada, materiais específicos e apoio da família. Estes resultados contribuem para o planejamento de cursos de formação de professores, visando o desenvolvimento de atitudes positivas: segurança no conhecimento científico, postura acolhedora, disponibilidade, respeito e tolerância, dentre outras, favorecendo a implementação da educação sexual na escola inclusiva.
Correlations between the simulated military tasks performance and physical fitness tests at high altitude
Authors: Neves Eduardo Borba
Published: November 2017

The aim of this study was to investigate the Correlations between the Simulated Military Tasks Performance and Physical Fitness Tests at high altitude. This research is part of a project to modernize the physical fitness test of the Colombian Army. Data collection was performed at the 13th Battalion of Instruction and Training, located 30km south of Bogota D.C., with a temperature range from 1ºC to 23ºC during the study period, and at 3100m above sea level. The sample was composed by 60 volunteers from three different platoons. The volunteers start the data collection protocol after 2 weeks of acclimation at this altitude. The main results were the identification of a high positive correlation between the 3 Assault wall in succession and the Simulated Military Tasks performance (r = 0.764, p<0.001), and a moderate negative correlation between pull-ups and the Simulated Military Tasks performance (r = -0.535, p<0.001). It can be recommended the use of the 20-consecutive overtaking of the 3 Assault wall in succession as a good way to estimate the performance in operational tasks which involve: assault walls, network of wires, military Climbing Nets, Tarzan jump among others, at high altitude.
Psycho/Bates Motel : hyperdiégèse et réactivation sélective
Authors: Boni Marta
Published: November 2017

Cette contribution propose un modèle pour l’analyse de la tendance contemporaine consistant à refaire, en série, un film culte. L’analyse de la série Bates Motel (A&E, 2013–), choisie comme exemple pertinent, s’appuie sur l’insertion de la série dans une sphère de discours plus large représentée par l’univers de Psycho et ses multiples incarnations médiatiques, incluant les appropriations « apocryphes » des téléspectateurs. Bates Motel correspond ainsi à l’exploration d’un espace. Ce phénomène est décrit à travers les concepts d’hyperdiégèse de Matt Hills (Fan Cultures, Londres, New York, Routledge, 2002), ainsi que de série culturelle et de musée imaginaire de Martin Lefebvre (Psycho : de la figure au musée imaginaire. Théorie et pratique de l’acte de spectature, Montréal, Paris, L’Harmattan, 1997). Les notions d’« activation » ou de « réactivation sélective » sont par ailleurs proposées et discutées.
Femmes auteures d’un homicide conjugal
Authors: Léveillée1 Suzanne , Trébuchon Clémentine
Published: November 2017

Étant donné que les femmes sont quatre fois plus susceptibles que les hommes d’être victimes d’un homicide conjugal, la plupart des recherches se centrent sur les hommes ayant tué leur conjointe ou leur ex-conjointe. Peu d’études portent sur les enjeux psychosociaux de femmes auteures d’un homicide conjugal. L’objet de notre article est d’étudier, dans une visée exploratoire, les caractéristiques criminologiques et les motivations de femmes auteures d’un homicide conjugal. Pour ce faire, une analyse exhaustive des dossiers du coroner en chef du Québec a été effectuée sur une période allant de 1989 à 2006, pour un total de 40 cas. Nos résultats indiquent que la moitié des femmes (50 %) ont été condamnées à purger une peine provinciale ou fédérale, 22,5 % ont été acquittées des accusations qui pesaient contre elles, 5 % ont été reconnues non responsables criminellement en raison d’un trouble mental grave, tandis que 12,5 % se sont suicidées à la suite du passage à l’acte homicide. Par ailleurs, plus de la moitié des femmes (57,5 %) se sont dénoncées à la suite de l’homicide, presque la moitié du groupe de femmes (47,5 %) ont utilisé un instrument perforant et 37,5 %, une arme à feu. Enfin, 17,5 % des femmes se sont acharnées sur leur victime au moment de l’homicide. En outre, les motivations retenues sont la dispute dans 25 % des cas, l’autodéfense dans 25 % des cas, la mesure de représailles dans 20 % des cas et 12,5 % des femmes ont passé à l’acte pour un motif financier.
Objets potentiellement dangereux et victimisation par les pairs à l’école secondaire
Authors: Clouston1 Catherine , Beaumont Claire , Frenette Éric , Leclerc Danielle
Published: November 2017

Cette étude consiste à déterminer la proportion des adolescents qui disent apporter des objets potentiellement dangereux à l’école et à décrire la nature de ces objets (ex. couteaux). De plus, elle vise à vérifier l’influence de la victimisation par les pairs sur le fait d’apporter des objets potentiellement dangereux à l’école en tenant compte de variables sociodémographiques. L’échantillon est composé de 27 709 élèves de la première à la cinquième secondaire en provenance de 52 écoles publiques du Québec. Les participants ont rempli le Questionnaire sur la sécurité et la violence à l’école révisé (QSVE-R) visant à dresser le portrait de la violence dans les établissements scolaires du Québec. Les résultats indiquent qu’au total, 5,1 % des élèves, davantage de garçons (8,2 %) que de filles (2,1 %), disent avoir déjà apporté un objet potentiellement dangereux à l’école. Cette proportion augmente selon l’âge, et le couteau est l’objet le plus mentionné par les répondants. Les résultats indiquent l’influence du sexe, de l’âge (variables contrôles) et de la victimisation de type direct (insultes-menaces et agressions physiques) sur le fait d’apporter un objet pouvant servir d’arme à l’école. Les conclusions soulèvent l’importance d’aider ces jeunes victimes à développer de meilleures stratégies afin de mieux gérer cette situation pénible, et proposent des pistes de réflexion pour orienter les interventions visant à créer des milieux scolaires sécurisants pour tous.
Dissuasion conditionnelle, programme d’accès graduel à la conduite et infractions routières
Authors: Poirier1 Brigitte , Blais Étienne , Faubert Camille
Published: November 2017

S’inspirant de la théorie de la dissuasion conditionnelle, cet article étudie la relation entre les restrictions associées au permis de conduire, les mécanismes de contrôles sociaux formels et informels et les intentions délictueuses au sein d’un échantillon de 392 jeunes détenteurs d’un permis de conduire régulier ou bien d’un permis restreint (probatoire ou d’apprenti). Dans le cadre du programme d’accès graduel à la conduite québécois, les titulaires d’un permis restreint ont entre autres un nombre limité de points d’inaptitude et sont soumis à une tolérance zéro relativement à l’alcool au volant. Les résultats des analyses de régression montrent que les détenteurs d’un permis restreint manifestent moins d’intentions délictuelles que ceux qui ont un permis régulier. Les résultats établissent également que les pairs délinquants ont moins d’influence sur les détenteurs d’un permis restreint comparativement à ceux qui détiennent un permis régulier. Enfin, l’internalisation de la norme apparaît comme le mécanisme qui prévient le plus efficacement les intentions délictuelles parmi tous les conducteurs.
Maintained avalanche dynamics during task-induced changes of neuronal activity in nonhuman primates
Authors: Yu Shan , Ribeiro Tiago L , Meisel Christian , Chou Samantha , Mitz Andrew , Saunders Richard , Plenz Dietmar
Published: November 2017

Sensory events, cognitive processing and motor actions correlate with transient changes in neuronal activity. In cortex, these transients form widespread spatiotemporal patterns with largely unknown statistical regularities. Here, we show that activity associated with behavioral events carry the signature of scale-invariant spatiotemporal clusters, neuronal avalanches. Using high-density microelectrode arrays in nonhuman primates, we recorded extracellular unit activity and the local field potential (LFP) in premotor and prefrontal cortex during motor and cognitive tasks. Unit activity and negative LFP deflections (nLFP) consistently changed in rate at single electrodes during tasks. Accordingly, nLFP clusters on the array deviated from scale-invariance compared to ongoing activity. Scale-invariance was recovered using ‘adaptive binning’, that is identifying clusters at temporal resolution given by task-induced changes in nLFP rate. Measures of LFP synchronization confirmed and computer simulations detailed our findings. We suggest optimization principles identified for avalanches during ongoing activity to apply to cortical information processing during behavior.
Two receptor tyrosine phosphatases dictate the depth of axonal stabilizing layer in the visual system
Authors: Hakeda-Suzuki Satoko , Takechi Hiroki , Kawamura Hinata , Suzuki Takashi
Published: November 2017

Formation of a functional neuronal network requires not only precise target recognition, but also stabilization of axonal contacts within their appropriate synaptic layers. Little is known about the molecular mechanisms underlying the stabilization of axonal connections after reaching their specifically targeted layers. Here, we show that two receptor protein tyrosine phosphatases (RPTPs), LAR and Ptp69D, act redundantly in photoreceptor afferents to stabilize axonal connections to the specific layers of the Drosophila visual system. Surprisingly, by combining loss-of-function and genetic rescue experiments, we found that the depth of the final layer of stable termination relied primarily on the cumulative amount of LAR and Ptp69D cytoplasmic activity, while specific features of their ectodomains contribute to the choice between two synaptic layers, M3 and M6, in the medulla. These data demonstrate how the combination of overlapping downstream but diversified upstream properties of two RPTPs can shape layer-specific wiring.
A matter of distribution: APC logic against consortial funding mechanism
Authors: Eve Martin Paul
Published: November 2017

Watch the VIDEO here.Article and Book Processing Charges have become one of the most common mechanisms for paying for gold open access. It is envisaged that this looks like a “flip” from a purchase model to a service model. However, the change in distribution that is effected in such a transition is substantial.In this talk, I will examine the economic distributions of APC mechanisms as opposed to consortial funding. I take examples from the monograph and journal publishing spaces. I also examine the distributional changes from the UK’s Research Excellence Framework’s proposed mandate for monographs. I finally then ask what the actual costs are in running a small scholarly publisher and how the distributional changes implied by APCs – a move from fixed costs to unit costs – hit such entities.In all, this talk aims to provoke discussion about alternative models and mitigating strategies for collectively underwriting open access.
Do economics journals foster replicable research?
Authors: Vlaeminck Sven , Toepfer Ralf
Published: November 2017

Watch the VIDEO here.Replications are pivotal for the credibility of empirical economics. It is widely recognized in economics that replication studies are a necessary condition for scientific integrity. Alarmingly, several studies indicate that a significant share of empirical economics research cannot be replicated. At the same time, the awareness among researchers, that empirically-based research is often based on shaky grounds, has increased in the last years. It becomes more and more evident that there is a need for more replications in economics to regain trust and credibility in empirical economics research.Though established scholarly journals have adopted replication policies in recent years, replication activities only slightly increased. Against this background our talk investigates if and how journals in economics foster replicable research. For this purpose, we will address two aspects:Journals’ data policies and their effective enforcement in economics: The first part of our talk presents the findings of a new study, in which we evaluated almost 600 articles published in 37 well-regarded journals with a data availability policy. First, we highlight the share of articles that fall under the data policy. Subsequently, the talk contrasts for how many of these data-based articles replication files were available in journals’ data archives and/or the supplemental information section of the article. Moreover, the exact requirements of journals’ data policies have been contrasted to the replication files available on journals’ web pages (respectively in their data archives).We developed a ‘compliance rate’ for each journal in our study. The higher the compliance rate the more do journals enforce their data policy. In the first part of our talk, we also discuss the question whether voluntary data policies are effective in fostering replicable research. For this purpose, we compare the compliance rate of journals with a voluntary data policy to their mandatory counterparts.Journals as publication outlets for replication studies: Though researchers agree that replication studies are needed to regain trust and credibility in empirical economic research, replication activities only slightly increased in recent years.  One reason for that finding can be that in the current system replicating other people’s result does not progresses researcher’s career. Another reason is the paucity of publication outlets for such replication studies. In this part of our talk we also discuss whether established journals should implement replication sections or whether a journal which is entirely dedicated to replication, would be a better way to foster the publication of replication studies. As a showcase we will briefly introduce the newly founded “International Journal for Re-Views in Empirical Economics” (IREE).To conclude, we sketch the current and potential future developments in economics when it comes to reproducible research.
Genome-wide identification and characterization of GRAS transcription factors in tomato (Solanum lycopersicum)
Authors: Niu Yiling , Zhao Tingting , Xu Xiangyang , Li Jingfu
Published: November 2017

Solanum lycopersicum, belonging to Solanaceae, is one of the commonly used model plants. The GRAS genes are transcriptional regulators, which play a significant role in plant growth and development, and the functions of several GRAS genes have been recognized, such as, axillary shoot meristem formation, radial root patterning, phytohormones (gibberellins) signal transduction, light signaling, and abiotic/biotic stress; however, only a few of these were identified and functionally characterized. In this study, a gene family was analyzed comprehensively with respect to phylogeny, gene structure, chromosomal localization, and expression pattern; the 54 GRAS members were screened from tomato by bioinformatics for the first time. The GRAS genes among tomato,Arabidopsis, rice, and grapevine were rebuilt to form a phylogenomic tree, which was divided into ten groups according to the previous classification ofArabidopsisand rice. A multiple sequence alignment exhibited the typical GRAS domain and conserved motifs similar to other gene families. Both the segmental and tandem duplications contributed significantly to the expansion and evolution of the GRAS gene family in tomato; the expression patterns across a variety of tissues and biotic conditions revealed potentially different functions of GRAS genes in tomato development and stress responses. Altogether, this study provides valuable information and robust candidate genes for future functional analysis for improving the resistance of tomato growth.
Assemblage and functional categorization of dung beetles (Coleoptera: Scarabaeinae) from the Pantanal
Authors: Pessôa Marcelo B. , Izzo Thiago J. , Vaz-de-Mello Fernando Z.
Published: November 2017

The Pantanal is one of the world’s largest tropical wetland areas and harbors high mammal biomass. There is no formal list of dung beetle species, and studies on their functional roles have never being carried out in Pantanal. In this study, we identified dung beetle species occurring in the north Pantanal region (Poconé sub-region, Brazil) and studied their functional organization, by measuring morphological, behavioral and phenological traits. We collected 25,278 individuals belonging to 17 genera and 35 species. We identified eight functional groups in the habitat: Noturnal Telecoprids, Diurnal Telecoprids, Nesting Endocoprids, Small Nonrollers, Nocturnal Nester Paracoprids, Big Nesters Paracoprids, Non Nesters Paracoprids and Diurnal Nesters Paracoprids. The functional groups were defined mostly by two reproductive traits and two niche differentiation traits related to the use of fecal resources. This high diversification of both species and functional roles shows the importance of the group in a habitat with strong variation in availability of habitat and resources.
EEG sensorimotor rhythms’ variation and functional connectivity measures during motor imagery: linear relations and classification approaches
Authors: Stefano Filho Carlos A. , Attux Romis , Castellano Gabriela
Published: November 2017

Hands motor imagery (MI) has been reported to alter synchronization patterns amongst neurons, yielding variations in the mu and beta bands’ power spectral density (PSD) of the electroencephalography (EEG) signal. These alterations have been used in the field of brain-computer interfaces (BCI), in an attempt to assign distinct MI tasks to commands of such a system. Recent studies have highlighted that information may be missing if knowledge about brain functional connectivity is not considered. In this work, we modeled the brain as a graph in which each EEG electrode represents a node. Our goal was to understand if there exists any linear correlation between variations in the synchronization patterns—that is, variations in the PSD of mu and beta bands—induced by MI and alterations in the corresponding functional networks. Moreover, we (1) explored the feasibility of using functional connectivity parameters as features for a classifier in the context of an MI-BCI; (2) investigated three different types of feature selection (FS) techniques; and (3) compared our approach to a more traditional method using the signal PSD as classifier inputs. Ten healthy subjects participated in this study. We observed significant correlations (p < 0.05) with values ranging from 0.4 to 0.9 between PSD variations and functional network alterations for some electrodes, prominently in the beta band. The PSD method performed better for data classification, with mean accuracies of (90 ± 8)% and (87 ± 7)% for the mu and beta band, respectively, versus (83 ± 8)% and (83 ± 7)% for the same bands for the graph method. Moreover, the number of features for the graph method was considerably larger. However, results for both methods were relatively close, and even overlapped when the uncertainties of the accuracy rates were considered. Further investigation regarding a careful exploration of other graph metrics may provide better alternatives.
Visual and acoustic components of courtship in the bird-of-paradise genusAstrapia(Aves: Paradisaeidae)
Authors: Scholes Edwin , Gillis Julia M. , Laman Timothy G.
Published: November 2017

The distinctive and divergent courtship phenotypes of the birds-of-paradise make them an important group for gaining insights into the evolution of sexually selected phenotypic evolution. The genusAstrapiaincludes five long-tailed species that inhabit New Guinea’s montane forests. The visual and acoustic components of courtship amongAstrapiaspecies are very poorly known. In this study, we use audiovisual data from a natural history collection of animal behavior to fill gaps in knowledge about the visual and acoustic components ofAstrapiacourtship. We report seven distinct male behaviors and two female specific behaviors along with distinct vocalizations and wing-produced sonations for all five species. These results provide the most complete assessment of courtship in the genusAstrapiato date and provide a valuable baseline for future research, including comparative and evolutionary studies among these and other bird-of-paradise species.
HgtSIM: a simulator for horizontal gene transfer (HGT) in microbial communities
Authors: Song Weizhi , Steensen Kerrin , Thomas Torsten
Published: November 2017

The development and application of metagenomic approaches have provided an opportunity to study and define horizontal gene transfer (HGT) on the level of microbial communities. However, no current metagenomic data simulation tools offers the option to introduce defined HGT within a microbial community. Here, we present HgtSIM, a pipeline to simulate HGT event among microbial community members with user-defined mutation levels. It was developed for testing and benchmarking pipelines for recovering HGTs from complex microbial datasets. HgtSIM is implemented in Python3 and is freely available at: https://github.com/songweizhi/HgtSIM.
Inorganic nutrients in the inundation channels of tidal marshes of a coastal lagoon of northwestern Baja California
Authors: Soto-Balderas MGL , Alvarez-Borrego S
Published: November 2017

We generated temperature, salinity, nitrate plus nitrite (NO3 + NO2), ammonia (NH4), and phosphate (PO4) time series for the mouth of three inundation channels of salt marshes of estero de Punta Banda, a coastal lagoon of northwestern Baja California. The channels are located near the lagoon’s mouth (B), at the middle (M), and at the internal extreme (C). Each channel was sampled twice, in August 1988. In each case, surface samples were taken every hour during twelve hours. Also, the main channel of the estero was sampled twice, at ten locations from the mouth to the internal extreme, to compare with the secondary channels. In these latter cases time series were not generated. We found highest salinity and nutrient values at channel C, where maximum salinity was 39.2‰, and maximum nutrient concentrations were 10 µM, 27 µM, and 7 µM, for NO3 + NO2, NH4, and PO4, respectively. B and M had similar values for water properties. Maximum S‰ and nutrient values for B and M were 36.0‰, and 4.9 µM, 24 µM, and 3.2 µM, for NO3 + NO2, NH4, and PO4, respectively. Higher values at C were due to higher residence time of water at the internal extreme of the lagoon. Our data do not support the hypothesis that nutrient concentrations of water ebbing from these inundation channels are higher than those of the lagoon’s main channel. Accumulation of nutrients and salt in channels B and M is lower than at C due to the former being closer to the lagoon’s mouth. Large residence times in the internal extreme of the lagoon make it very vulnerable to the input of pollutants.
The trace metal chemistry of a tropical hypersaline basin: Evidence from field and laboratory experiments
Authors: Mee LD , Osuna-López JI
Published: November 2017

Field observations were made of the distribution of trace metals in water and sediments along a chlorinity gradient from 20-160‰ in the seasonally hypersaline Ceuta lagoon, Sinaloa, Mexico. The observations revealed a non-consecutive behaviour of the metals (with respect to chlorinity) with a rapid loss of metals to the sediments from chlorinity 20-50‰, a net desorption of metals from the sediments from 50-155‰ and finally, precipitation with halite or the last bitters. Radiochemical laboratoty experiments were performed to examine possible solid-solution formation of Ni, Co and Mn with the calcium carbonate and gypsum phases formed during seawater evaporation and the partition of Co and Mn between suspended sediments and seawater throughout the chlorinity range of the lagoon. From the laboratory experiments and a simple descriptive model of a hypersaline basin, it was concluded that the behaviour of trace metals in the lagoon results from variations in the adsorption/desorption equilibria with the sediments rather than solid solution formation.
Activity of the mexican purse seine fleet and the feeding habits of yellowfin tuna
Authors: Ortega-García S , Galván-Magaña F , Arvizu-Martínez J
Published: November 2017

Results of the analysis of information taken from fishing logbooks and samples obtained from the Mexican purse seine fleet are presented. This information was analyzed independently of the size of the ships and areas of operation. The study includes the time of beginning of sets and the time they were made, the relationship between the number of sets and the time they were made and the monthly variation in 1985. A comparison is made between this information and food volume of yellowfin tuna. It was found that the sets of yellowfin were made almost entirely during daylight hours as observed from the two modal intervals in nearly all the months analyzed; the first one occurs during the morning and the second one during the afternoon. The minimum of sets was registered between 11:00-13:00 hours; only in one case out of the 12 analyzed did the minimum occur between 13:00-14:00 hours (May). Various degrees of gastric depletion were observed throughout the day. However, at 13:00 and 14:00 hours the stomachs were nearly empty, forcing the tuna to look for food in deeper waters, because at this time of day light penetration is maximal, thus leading to a descent of the prey and lowering the vulnerability of the tuna to the fishing fleet. This, in turn, could account for the lesser number of sets at this hour of the day. The most important preys were: red crab (Pleuroncodes planipes), cephalopods Argonauta sp., Dosidicus gigac, Symplectoteuthis ovalaniensis and Onychoteuthis banksii) and the Pacific mackerel (Scomber japonicus).
Comparative study of the degree of incidence of macroparasites in six species of sebastes (Pisces, Scorpaenidae) from the northwestern coast of Baja California, Mexico
Authors: Alvarado-Villamar MR , Ruiz-Campos G
Published: November 2017

A qualitative and quantitative study on infestation levels by macroparasites was carried out for six rockfish species of the genus Sebastes (S. constellatus, S. elongatus, S. rosaceus, S. umboxus, S. helvomaculatus and S. chlorostictus). This analysis was made on 220 specimens from commercial catches from Apri1 1989 to February 1990, in several localities along the northwestem coast of Baja California, Mexico, between Coronado Island and San Quintín Bay. The number of macroparasites on the different affected organs was analysed for each rockfish species, as well as for each size class and sex. The nematode (Anisakis sp.) and monogenea tremato de (Microcotyle sp.) were registered in all the species of rockfish but others, such as the anchar parasite copepod (Lemaea sp.) and digenea trematode (Opecoelus sp.), were of exclusive occurrence in S. umbrosus and S. rosaceus, respectively. Nematodes were the most dominant parasites in all the rockfish species, with an incidence percent of 82.4, followed by digenea trematodes (9.5%) and cestode worms (3.1%). The average number of macroparasites was different among the six rockfish species, being S. helvomaculatus the species with higher number of macroparasites. The average number of macroparasites between sexes was different for each rockfish species, except in S. constellatus. We did not register significant differences in the average number of parasites among size classes for each rockfish species.
Mesenteric Lymphatic Malformations in Children: Report of 7 Cases
Authors: Shironomae Tsubasa , Nishida Shoichi , Satomi Miwa , Kuwahara Tsuyoshi , Yasui Yoshitomo , Kohno Miyuki
Published: November 2017

Introduction

Mesenteric lymphatic malformations (MLMs) are rare, the most common etiology being benign proliferation of ectopic lymphatics in the mesentery, with these lymphatics lacking communication with the remainder of the lymphatic system.

Case presentation

The medical records of 7 patients treated for MLMs at our center between 2001 and 2015 were reviewed. The 7 patients included 4 boys and 3 girls of a median age of 96 months (range: 4–161 months). The main symptoms were abdominal pain in 5 patients, fever in 2, and vomiting in 2. Four of the 5 patients with abdominal pain had elevated inflammatory reactions. Five patients had abdominal masses, and 2 had asymptomatic abdominal masses incidentally diagnosed during infant health checkups. Of the 4 patients with elevated inflammatory reactions, 2 required emergency surgery, and the other 2 underwent surgery after antibiotic treatment. MLMs were located in the jejunal mesentery of 3 patients, in the ileal mesentery in 3, and in the transverse mesocolon in 1. Surgical procedures included excision of the MLMs and adjacent segment of the intestine in 4 patients and cystectomy in 3. No patient experienced recurrence of MLM.

Conclusions

Clinical features of MLMs can vary from asymptomatic to acute abdominal pain and may affect adjacent organs. MLM should be treated surgically before it can cause serious complications.

Potencial neuroprotetor, antioxidante e anti-inflamatório do Canabidiol: relevância e perspectivas para o tratamento de doenças neurodegenerativas.
Authors: Ebling Flores Leandro , Zamin Lauren Lúcia
Published: November 2017

Introdução: a incidência de doenças neurodegenerativas tem aumentado nos últimos anos, passando a constituir um problema de saúde pública. Frente a isso se faz necessário o desenvolvimento de novas modalidades terapêuticas visando evitar, recuperar ou impedir as alterações celulares que possam levar à morte neuronal. Objetivo: realizar uma revisão bibliográfica acerca do potencial neuroprotetor, antioxidante e anti-inflamatório do Canabidiol (CBD) investigando sua ação sobre processos neurodegenerativos associados à doença de Alzheimer, Parkinson e Huntington. Metodologia: foi realizado um estudo descritivo e qualitativo desenvolvido na forma de revisão bibliográfica onde foram utilizados artigos disponíveis nos bancos de dados PubMed, Scielo e Scopus com o período de referência compreendido entre os anos de 1998 e 2016. Resultados: foram selecionados 10 artigos que tratavam do tema e todos eles mostraram que o CBD induziu neuroproteção e possuiu propriedades antioxidantes e anti-inflamatórios em diferentes modelos de citotoxicidade, estresse oxidativo e neurodegeneração. Conclusão: o CBD pode ser um importante agente terapêutico no tratamento, na prevenção e na reversão de lesões oriundas de doenças neurodegenerativas. Entretanto, há necessidade de reforçar estudos e ensaios em modelos animais antes de transpor o uso do CBD para humanos.

Published: November 2017

Introdução: as unidades de terapia intensiva frequentemente utilizam dispositivos invasivos, como os cateteres, os quais podem desencadear complicações como infecção e outros efeitos colaterais que são de grande importância na terapia clínica. Além disso, os cateteres venosos utilizados principalmente em unidades de terapia intensiva contribuem para disseminação de infecção hospitalar. Objetivo: avaliar os microrganismos causadores de infecções em ponta de cateter venoso usado nos pacientes hospitalizados na Santa Casa de Misericórdia de Cuiabá-MT. Metodologia: foi realizado um estudo transversal de natureza clínica, incluindo pacientes que tinham cateter venoso e excluídos os pacientes com sonda vesical. Foi utilizada a Técnica Semi quantitativa de Maki para cultivo e após o período de incubação, as placas com crescimento igual ou superior a 15 UFC, foram submetidas à identificação dos microrganismos através de provas bioquímicas.

This work presents a new database of SO2 and CO2 fluxes from the Southern Central American Volcanic Arc (SCAVA) for the period 2015–2016. We report ∼300 SO2 flux measurements from 10 volcanoes and gas ratios from 11 volcanoes in Costa Rica and Nicaragua representing the most extensive available assessment of this ∼500 km arc segment. The SO2 flux from SCAVA is estimated at 6,240 ± 1,150 T/d, about a factor of three higher than previous estimations (1972–2013). We attribute this increase in part to our more complete assessment of the arc. Another consideration in interpreting the difference is the context of increased volcanic activity, as there were more eruptions in 2015–2016 than in any period since ∼1980. A potential explanation for increased degassing and volcanic activity is a change in crustal stress regime (from compression to extension, opening volcanic conduits) following two large (Mw > 7) earthquakes in the region in 2012. The CO2 flux from the arc is estimated at 22,500 ± 4,900 T/d, which is equal to or greater than estimates of C input into the SCAVA subduction zone. Time‐series data sets for arc degassing need to be improved in temporal and spatial coverage to robustly constrain volatile budgets and tectonic controls. Arc volatile budgets are strongly influenced by short‐lived degassing events and arc systems likely display significant short‐term variations in volatile output, calling for expansion of nascent geochemical monitoring networks to achieve spatial and temporal coverage similar to traditional geophysical networks.
Goethite Concentration Variations in the Red Clay Sequence on the Chinese Loess Plateau
Authors: Zhang Rui , Nie Junsheng
Published: November 2017

The Goethite is a common magnetic mineral in soils and is important for understanding past climatic and environmental change. Although goethite concentration records are available for the Quaternary loess‐paleosol sequences from the Chinese Loess Plateau (CLP), no goethite concentration record is available for the underlying Red Clay sequence. Here, we generate a record of goethite concentration from the Chaona section on the CLP and investigate the relationship between goethite and ferrimagnetic mineral concentration and climate parameters on the Red Clay sequence deposited from 6 to 2.7 Ma. We found that increasing goethite concentration generally corresponds to decreasing magnetic susceptibility for the Red Clay sequence, with the exception of an anomalous section from 4.3 to 3.7 Ma where both records show increasing trends. Precipitation seasonality could explain this opposite variation pattern between magnetic susceptibility and goethite concentration in the Red Clay sequence. From 3.6 to 2.7 Ma, goethite concentration has a decreasing trend while magnetic susceptibility increased, which we interpret as more seasonally distributed precipitation associated with intensification of the East Asian summer monsoon (EASM). Similar pattern was observed from 0.65 to 0 Ma from the Lingtai section. Taken together, the goethite record reveals that the EASM experienced two stages of rapid intensification with apparent seasonally distributed precipitation since 6 Ma.

With the conclusion of the Cassini mission, we present an updated topographic map of Titan, including all the available altimetry, SARtopo, and stereophotogrammetry topographic data sets available from the mission. We use radial basis functions to interpolate the sparse data set, which covers only ∼9% of Titan's global area. The most notable updates to the topography include higher coverage of the poles of Titan, improved fits to the global shape, and a finer resolution of the global interpolation. We also present a statistical analysis of the error in the derived products and perform a global minimization on a profile‐by‐profile basis to account for observed biases in the input data set. We find a greater flattening of Titan than measured, additional topographic rises in Titan's southern hemisphere and better constrain the possible locations of past and present liquids on Titan's surface.

We utilize suprathermal ion and magnetic field measurements from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, organized by the upstream magnetic field, to investigate the morphology and variability of flows, fields, and forces in the Mars‐solar wind interaction. We employ a combination of case studies and statistical investigations to characterize the interaction in both quasi‐parallel and quasi‐perpendicular regions and under high and low solar wind Mach number conditions. For the first time, we include a detailed investigation of suprathermal ion temperature and anisotropy. We find that the observed magnetic fields and suprathermal ion moments in the magnetosheath, bow shock, and upstream regions have observable asymmetries controlled by the interplanetary magnetic field, with particularly large asymmetries found in the ion parallel temperature and anisotropy. The greatest temperature anisotropies occur in quasi‐perpendicular regions of the magnetosheath and under low Mach number conditions. These results have implications for the growth and evolution of wave‐particle instabilities and their role in energy transport and dissipation. We utilize the measured parameters to estimate the average ion pressure gradient, J × B, and v × B macroscopic force terms. The pressure gradient force maintains nearly cylindrical symmetry, while the J × B force has larger asymmetries and varies in magnitude in comparison to the pressure gradient force. The v × B force felt by newly produced planetary ions exceeds the other forces in magnitude in the magnetosheath and upstream regions for all solar wind conditions.
Simulated Historical (1901–2010) Changes in the Permafrost Extent and Active Layer Thickness in the Northern Hemisphere

Published: November 2017

A growing body of simulation research has considered the dynamics of permafrost, which has an important role in the climate system of a warming world. Previous studies have concentrated on the future degradation of permafrost based on global climate models (GCMs) or data from GCMs. An accurate estimation of historical changes in permafrost is required to understand the relations between changes in permafrost and the Earth's climate and to validate the results from GCMs. Using the Community Land Model 4.5 driven by the Climate Research Unit ‐National Centers for Environmental Prediction (CRUNCEP) atmospheric data set and observations of changes in soil temperature and active layer thickness and present‐day areal extent of permafrost, this study investigated the changes in permafrost in the Northern Hemisphere from 1901 to 2010. The results showed that the model can reproduce the interannual variations in the observed soil temperature and active layer thickness. The simulated area of present‐day permafrost fits well with observations, with a bias of 2.02 × 106 km2. The area of permafrost decreased by 0.06 (0.62) × 106 km2 decade−1 from 1901 to 2009 (1979 to 2009). A clear decrease in the area of permafrost was found in response to increases in air temperatures during the period from about the 1930s to the 1940s, indicating that permafrost is sensitive to even a temporary increase in temperature. From a regional perspective, high‐elevation permafrost decreases at a faster rate than high‐latitude permafrost; permafrost in China shows the fastest rate of decrease, followed by Alaska, Russia, and Canada. Discrepancies in the rate of decrease in the extent of permafrost among different regions were mostly linked to the sensitivity of permafrost in the regions to increases in air temperatures rather than to the amplitude of the increase in air temperatures. An increase in the active layer thickness of 0.009 (0.071) m decade−1 was shown during the period of 1901–2009 (1979–2009). These results are useful in understanding the response of permafrost to a historical warming climate and for validating the results from GCMs.
The Temporal and Spatial Variability of the Confined Aquifer Head and Storage Properties in the San Luis Valley, Colorado Inferred From Multiple InSAR Missions

Published: November 2017

Interferometric Synthetic Aperture Radar (InSAR) data from multiple satellite missions were combined to study the temporal and spatial variability of head and storage properties in a confined aquifer system on a decadal time scale. The area of study was a 4,500 km2 agricultural basin in the San Luis Valley (SLV), Colorado. We had available previous analyses of C‐band ERS‐1/2 data from June 1992 to November 2000, and L‐band ALOS PALSAR data from October 2009 to March 2011. We used C‐band Envisat data to fill in the time period from November 2006 to July 2010. In processing the Envisat data, we successfully employed a phase interpolation between persistent scatterer pixels to reduce the impact of vegetation decorrelation, which can significantly reduce the quality of C‐band InSAR data over agricultural basins. In comparing the results from the L‐band ALOS data and C‐band Envisat data in a 10 month overlapping time period, we found that the shorter wavelength of C‐band InSAR allowed us to preserve small deformation signals that were not detectable using L‐band ALOS data. A significant result was the finding that the elastic storage properties of the SLV confined aquifer system remained stable over the 20 year time period and vary slowly in space, allowing us to combine InSAR data acquired from multiple missions to fill the temporal and spatial gaps in well data. The InSAR estimated head levels were validated with well measurements, which indicate little permanent water‐storage loss over the study time period in the SLV.
