L' impact des relations interpersonnelles et du soutien social sur la santé psychologique des policiers
Authors: Deschênes Andrée-Ann , Rodrigue Audrey , Gagnon Kimberley D.
Published: March 2020

Selon la littérature, le travail du policier est un métier à risque étant donné son contexte d’intervention souvent urgent et imprévisible (De Soir, Daubechies et Van den Steene, 2012; cités par Desjardins, 2018). Le métier de policier comporte également un double mandat, soit celui de protéger la population tout en faisant régner l’ordre (Oligny, 1991). Ces particularités rendent le travail des policiers plus à risque que d’autres métiers sur le plan de la santé mentale (Marchand, 2007). Malgré l’importance accordée à la santé au travail et les risques associés au métier de policier, peu d’études empiriques sont répertoriées à ce sujet au sein de cette population. Silveri (2017) a identifié dans son article le soutien social par les collègues et par les supérieurs comme faisant partie des ressources les plus importantes pour atténuer les « effets des exigences du travail sur le stress ». La présente recherche s’intéresse plus spécifiquement à l’effet des relations interpersonnelles (variable indépendante) et du soutien social (variable indépendante) sur la santé psychologique des policiers (variable dépendante). Le modèle théorique de Gilbert, Dagenais-Desmarais et Savoie (2011) a été retenu pour définir la variable dépendante composée du bien-être psychologique (BEPT; sérénité, engagement et harmonie sociale) et de la détresse psychologique (DET; anxiété, désengagement et irritabilité). La présente étude suppose que la qualité perçue des relations interpersonnelles avec les collègues et le supérieur ainsi que le soutien social sont reliés positivement au bien-être psychologique. L’étude suppose également que la qualité des relations  et le soutien social [...]
Intégrer ou segmenter travail et famille? Vers une nouvelle compréhension des effets de la charge de travail
Authors: Trottier Mélanie , Foisy Petaccia Stéphanie
Published: March 2020

Les récentes modifications de l’organisation du travail, telles que l’utilisation accrue de la technologie, ont transformé les frontières entre les domaines du travail et de la famille modifiant ainsi la définition même de la charge de travail. En effet, le temps et le lieu de travail sont désormais flexibles. Il importe de se questionner sur les réels effets de cette pression d’intégrer les rôles du travail et de la famille qui redéfinit la répartition de la charge de travail. La présente recherche s’intéresse à la fonction modératrice de la segmentation des rôles dans la relation entre la charge de travail et le conflit travail-famille. Une collecte de données a été réalisée auprès de 162 pharmaciens et pharmaciennes membres de l’Ordre des pharmaciens du Québec. Les résultats obtenus sont contraires à ce qui était attendu : la segmentation des rôles ne protège pas les individus d’une charge de travail élevée, mais accentue plutôt son effet sur le conflit travail-famille. La présente recherche offre un avancement des connaissances dans la littérature portant sur l’interface travail-famille. En effet, elle ouvre une voie intéressante pour comprendre dans quelles situations la segmentation des rôles influence le conflit travail-famille. D’un point de vue professionnel, la présente étude aidera les employeurs à comprendre la complexité des effets d’une charge de travail qui peut désormais être effectuée en dehors du cadre traditionnel du lieu de travail.
Peut-on gérer la performance et le bien-être des employés? Une revue de littérature et quelques propositions de recherche sur les pratiques innovantes en gestion de la performance
Authors: Doucet Olivier , Giamos Dimitris , Lapalme Marie-Ève
Published: March 2020

Le présent article vise à synthétiser les connaissances actuelles en regard des pratiques émergentes de gestion de la performance qui ont pour but de favoriser la performance et le bien-être des employés au travail. Plus précisément, cet article discute des connaissances à ce jour et des zones grises pour chacune des trois pratiques suivantes : 1) l’abandon des cotes de performance; 2) l’arrimage de la gestion de la performance avec le développement des employés; 3) la gestion de la performance par les forces. Des organisations réputées comme Adobe et Deloitte ont été à l’avant-garde de ces nouvelles pratiques et plusieurs organisations adoptent leurs démarches. Toutefois, les praticiens et les chercheurs ne connaissent pas nécessairement encore tous les impacts de ces pratiques à long terme. L’efficacité et la pertinence de chacune de ces pratiques dans le monde de la gestion sont discutées, tout en considérant l’aspect du bien-être des employés. Étant donné le manque relatif de connaissances sur l’abandon des cotes de performance, l’accent sur le développement et la gestion de la performance par les forces, l’article ouvre également sur des pistes prometteuses pour les chercheurs. Ces propositions de recherche pourraient aider les praticiens et les chercheurs à éventuellement répondre aux défis qui confrontent actuellement les organisations en matière de gestion de la performance.

Authors: Desmeules Amelie , Hamel Christine , St-Pierre Marie-Catherine , Desmarais Chantal
Published: March 2020

Afin d’assurer le développement professionnel d’enseignants quant à l’enseignement des habiletés langagières réceptives, socle de l’apprentissage de compréhension de lecture, cette recherche-action visait à mettre en place et à documenter une communauté de pratique (CoP) en ligne. L’évolution des interactions dans la CoP a été analysée et des profils de participation ont été dégagés. Les résultats démontrent que les interactions de la deuxième phase de la CoP contribuent davantage à l’avancement du discours collectif et à la pérennité du modèle que celles de la première. Des recommandations sont émises quant à la mise en place des CoP et leur pérennisation.

Published: March 2020

During differentiation, oligodendrocyte precursor cells (OPCs) extend a network of processes that make contact with axons and initiate myelination. Recent studies revealed that actin polymerization is required for initiation of myelination whereas actin depolymerization promotes myelin wrapping. Here, we used primary OPCs in culture isolated from neonatal rat cortices of both sexes and young male and female mice with oligodendrocyte-specific deletion of mechanistic target of rapamycin (mTOR) to demonstrate that mTOR regulates expression of specific cytoskeletal targets and actin reorganization in oligodendrocytes during developmental myelination. Loss or inhibition of mTOR reduced expression of profilin2 and ARPC3, actin polymerizing factors, and elevated levels of active cofilin, which mediates actin depolymerization. The deficits in actin polymerization were revealed in reduced phalloidin and deficits in oligodendrocyte cellular branching complexity at the peak of morphologic differentiation and a delay in initiation of myelination. We further show a critical role for mTOR in expression and localization of myelin basic protein (Mbp) mRNA and MBP protein to the cellular processes where it is necessary at the myelin membrane for axon wrapping.MbpmRNA transport deficits were confirmed by single molecule RNA FISH. Moreover, expression of the kinesin family member 1B, anMbpmRNA transport protein, was reduced in CC1+ cells in themTOR cKOand in mTOR inhibited oligodendrocytes undergoing differentiationin vitro. These data support the conclusion that mTOR regulates both initiation of myelination and axon wrapping by targeting cytoskeletal reorganization and MBP localization to oligodendrocyte processes.

SIGNIFICANCE STATEMENTMyelination is essential for normal CNS development and adult axon preservation and function. The mechanistic target of rapamycin (mTOR) signaling pathway has been implicated in promoting CNS myelination; however, there is a gap in our understanding of the mechanisms by which mTOR promotes developmental myelination through regulating specific downstream targets. Here, we present evidence that mTOR promotes the initiation of myelination through regulating specific cytoskeletal targets and cellular process expansion by oligodendrocyte precursor cells as well as expression and cellular localization of myelin basic protein.

Lifestyle modifications, including physical exercise (PhyEx), are well-known treatments for metabolic syndrome (MetS), a cluster of metabolic and cardiovascular risk factors often associated to hypogonadism. Given the trophic role of testosterone on skeletal muscle (SkM), this study was aimed at evaluating the effects of testosterone treatment on SkM metabolism and exercise performance in male rabbits with high-fat diet (HFD)-induced MetS. HFD rabbits, treated or not with testosterone (30 mg/kg/week) for 12 weeks, were compared to regular diet animals (RD). A subset of each group was exercise-trained for 12 weeks. HFD increased type-II (fast, glycolytic) and decreased type-I (slow, oxidative) muscle fibers compared to RD as evaluated by RT-PCR and histochemistry. Testosterone reverted these effects, also inducing the expression of mitochondrial respiration enzymes and normalizing HFD-induced mitochondrial cristae reduction. Moreover, testosterone significantly increased the expression of myogenic/differentiation markers and genes related to glucidic/lipid metabolism. At the end of the PhyEx protocol, when compared to RD, HFD rabbits showed a significant reduction of running distance and running time, while testosterone counteracted this effect, also decreasing lactate production. In the trained groups, muscle histology showed a significant reduction of oxidative fibers in HFD compared to RD and the positive effect of testosterone in maintaining oxidative metabolism, as also demonstrated by analyzing mitochondrial ultrastructure, succinate dehydrogenase activity and ATP production. Our results indicate that testosterone could be useful to promote oxidative muscle metabolism altered by MetS, thus improving exercise performance. Conversely, testosterone administration to otherwise eugonadal rabbits (RD) only increased muscle fiber diameter but not endurance performance.
Fidel Castro en Sierra Maestra. Recorrido de una fotografía (1958)
Authors: Camacho Navarro Enrique
Published: March 2020

The Cuban revolution is a process in which the production of images is a fundamental part to explain its historical development. Through a photograph of Fidel Castro, captured by the Spanish photojournalist Enrique Meneses, the possibility of making a story is shown -in accordance with the proposal of John Mraz- with and over photographs. This iconographic representation, taken by Fidel Castro in the Sierra Maestra in the first months of 1958, and which was integrated into the edition of a book by the same photographer, offers a good opportunity to reflect on the contributions that iconology has in the Circumcaribe, and throughout Latin America.
Las representaciones del Caribe en El gran zoo de Nicolás Guillén
Authors: Vidal Ortega Carlos Federico
Published: March 2020

El gran zoo (1984), by the Cuban poet Nicolás Guillén, offers various representations of the Caribbean. The article argues that this poetry book falls within the tradition of the Post Avant-garde literary movement in Spanish America. Additionally, various formal characteristics of the text are examined, as exemplified in the poems “The Dream” and “Guitar”. Another poem that receives close attention is “The Tenor”, which parodies the division between high culture and popular culture. Lastly, several allusions of the poetry book to the historical context of the Cold War and the Space Race are analyzed.
Terrenos revolucionarios: precariedad y contingencia social y ecológica en el documental nicaragüense Palabras mágicas (para romper un encantamiento) (2012) de Mercedes Moncada
Authors: List Jared
Published: March 2020

This essay examines the relationality and representation of Nicaraguans and nature through frameworks of precarity and ecocriticism. The documentary film Palabras mágicas (para romper un encantamiento) (2012) by Mercedes Moncada presents the earth as an extension of the self, firstly, as an allegory of the country, the revolution and the individual, and, secondly, through the contingency and vulnerability of the environment and Nicaragua’s people. Both Nicaraguans and nature are victims of a political system that repeats itself during the 20th and 21st centuries. Through the notions of corporality and materiality, the documentary establishes a link between the Nicaraguan subject and land through their discursivity, both as sites of inscription that are subject to relations of power, a fact that makes them both precarious. Palabras mágicas (2012) proposes that both are victims the somocismo of the 20th century and Ortega’s neosandismo of the 21st century. Finally, from the metaphorical link between Nicaragua’s environment and people, one of the results is framing the environment within a framework of precarity and vulnerability, highlighting contingency and dependency between both humans and itself.

Published: March 2020

Este artículo tiene por objetivo indagar, a través del ingreso y su estructura, si la descampesinización ha comenzado a mermar para así poder ver si las condiciones de pobreza extrema a la que se enfrentan las localidades indígenas en México han disminuido. Para ello, se analizaron los resultados de la Encuesta Nacional de Ingreso y Gasto de los Hogares (ENIGH) en México 2012, 2014 y 2016. Entre los resultados más relevantes se hallaron indicios de pobreza extrema en estados principalmente del sur de México y una caída notoria enlos ingresos por trabajo y comportamiento irregular en los ingresos relacionados con la producción agrícola, lo que lleva a cuestionar la eficacia de las políticas federales de desarrollo económico.
Pasado y presente de los pueblos que visitó el extirpador de idolatrías Bernardo de Noboa
Authors: Robles Mendoza Román
Published: March 2020

En este trabajo hacemos una revisión contemporánea acerca de la continuidad y de la desaparición de pueblos que visitó Bernardo de Noboa en el siglo xvii en su misión de extirpar idolatrías de indios «paganos» de la región Cajatambo. Esta empresa eclesiástica fue emprendida más de un siglo después de la conquista española, cuando los esfuerzos de la cristianización de indígenas habían fracasado en todo el domino castellano. El Arzobispado de Lima emprendió —desde Bartolomé Lobo Guerrero hasta Pedro de Villagómez—, por etapas sucesivas, una política de persecución y represión a los sacerdotes andinos y la destrucción de ídolos sagrados de los pueblos vencidos, con el propósito de cortar de raíz el sistema de creencia andina y profundizar la evangelización en la conciencia de los nativos. En ese entonces, los pueblos por donde recorrió la comisión extirpadora, era la parte norte de Cajatambo, principalmente las localidades adscritas al curato de Ticllos. Presentamos este trabajo comparativo de los pueblos andinos de la región, antiguos y actuales, con los datos que proporcionan los documentos coloniales y la etnografía de la región trabajada durante las últimas décadas de estos tiempos.

Genre as a Category of Poetics (Problems, Tendencies, Perspectives)
Authors: Zavarkina Marina V.
Published: March 2020

The article is focused on one of the key categories of historical and theoretical poetics — the category of genre. Until now, many issues related to genre and the genre analysis of a writing remain unsettled. The article considers the main problems of studying the category of genre, as well as different approaches: genetic, functional, systemic, typological ones. The emphasis is laid on the history of the study of the category “genre” by formal and sociological schools. A particular attention is paid to the contribution of P. N. Medvedev to the development of the genre as a category of poetics, as well as to the concepts of the genre by D. S. Likhachev, M. M. Bakhtin, G. N. Pospelov, V. V. Kozhinov, V. N. Zakharov, L. V. Chernets, N. L. Leiderman and others, some aspects of studying the category of genre in foreign literary criticism are considered. It is proved that, despite the idea of “atrophy”, the genre still remains significant both for the writer’s artistic thinking and for certain “expectations” of the reader from the text.

Published: March 2020

This research aims to study on the disinfection efficiency of Hoa Sen medical instrument sterilizing equipment based on the application of ECA technology at General Hospital and Obstetrics and Paediatrics Hospitals in Tra Vinh. Disinfection using ECA technology is a method that does not require the introduction of special oxidizing agents except of water and salt. ECA solution - Anolyte solution has very strong oxidants, which oxidize components such as protein, lipid, etc. (usually of the bacterial cell membrane) that make the cell membrane decomposed, reducing 77−93% of the respiratory ability of bacterial cells, weakening them and eventually being destroyed. Hoa Sen medical instrument sterilizing equipment has a similar construction form as a regular double washing table with two wash basins, wherein one sink with a faucet which produces purified water, while other one has a faucet that gives anolyte solution for sterilization. Both faucets are based on a touch support. At the bottom of the sink an anolyte solution production system was installed. Valorization of the disinfection ability of the Hoa Sen medical instrument sterilizing equipment was based on the determination of the number of microorganisms on the surface of the instrument before and after being soaked with an antiseptic washing table. Microbiological criteria are the number of aerobic bacteria, E. Coli and Coliforms. Analytical samples were quantified by culture method on agar plates. Analysis of total aerobic bacteria, E. Coli and Coliforms bacteria according to Vietnam Standard TCVN 4884:2015, TCVN 6846:2007 and TCVN 6848:2007, respectively. The results showed that bacterial removal efficiency was elevated with a novel Hoa Sen sterilizing equipment anolyte. In laboratory scale, E. Coli and Coliforms bacteria with a density of 105 CFU/mL were completely removed in 30 sec contact with an anolyte solution of 300 mg/L active chlorine concentration. In hospital scale, the removal efficiency of total aerobic bacteria on the surface of medical instruments after surgery was 99% for one minute disinfection time. For E. Coli and Coliforms bacteria, the results of the analysis were not detected in both cases before and after sterilization.

Authors: Linh Nguyen Thuy , Ly Luu Han , Duong Nguyen Thuy , Hue Huynh Thi Thu
Published: March 2020

C-repeat binding factor (CBF) proteins are transcription factors involved in plant response to abiotic stresses, especially low-temperature condition. In this research, a CBF3-coding gene was isolated from a cold-acclimation maize variety, Zea mays var. Tevang-1 and denoted as ZmCBF3tv. The isolated gene shared 96.49% homology with the B73-reference gene and had no intron in the coding sequence. By using bioinformatic tools, a number of variations in the nucleotide and amino acid sequences were identified. An alignment between ZmCBF3tv and other CBF/DREB1 proteins from various species revealed functional regions and typical features, such as nuclear localization signal (NLS), the AP2 DNA-binding domain, and acidic-amino-acid-rich segments. Additionally, a phylogenetic analysis based on the AP2 domain showed that the maize CBF3 transcription factor had the highest similarity with that from rice and closely related to other DREB1/CBF protein of monocots. The function of the ZmCBF3tv product is suggested to be a CBF/DREB1 transcription factor.

Published: March 2020

Huperzia serrata is a precious medicinal plant used in medicine to support and treat Alzheimer's disease. Currently, this species is in danger of extinction due to indiscriminate exploitation for commercial purposes. Furthermore, this species reproduces slowly and is difficult to cultivate artificially. The reproduction by spores of this species is very long and takes 15−20 years from the spore germination to mature plant, whereas asexual reproduction by tissue culture is also difficult. Therefore, cutting is an effective method to propagate this species on a large scale. In this study, we surveyed the factors affecting the survival rate, the rooting and the number of new leaves of the stem cuttings, including cutting length, growing substrate, and effects of growth-regulating hormones IBA (0 ppm, 500 ppm, 1000 ppm, 2000 ppm and 3000 ppm) and α-NAA (0 ppm, 10 ppm, 20 ppm, 30 ppm and 40 ppm). The experimental results showed that using cuttings of 6 cm in length treated with IBA at a concentration of 1000 ppm for 30 mins and cultured on the substrate mixture of soil, decomposed animal manure and rice husk at a ratio of 3:1:1 was the best for cuttings of H. serrata in Sa Pa. The results of this study will contribute to the conservation and development of genetic source of H. serrata in Vietnam.
First records of bats (Mammalia: Chiroptera) from Son La city, Northwestern Vietnam, with remarks on their conservation status
Authors: Loi Dao Nhan
Published: March 2020

Son La is a well-known city in the Northwestern region of Vietnam for its outstanding landscapes. It contains a variety of ecosystems ranging from farming area, valleys, forests on hills and karst with cave systems. Natural habitats of the city would be suitable for many bat species. However, bats of the city were not included in any literature. Between March 2014 and June 2018, we conducted a series of bat surveys in this city using mist nets and harp traps. Results from our study indicated that Son La city is a home to at least 21 bat species belonging to 9 genera, 6 families. Of which, Rhinolophus thomasi was listed as “VU” (Vulnerable) in the 2007 Red Book of Vietnam and Myotis annamiticus was listed in the IUCN Redlist of the Threatened Species as “DD” (Data Deficient). This paper provides the first data on bats of Son La city with morphological measurements and conservation status of each recorded species.
Isolation and identification of indole acetic acid producing bacteria from the coasts of Ben Tre and Tra Vinh Provinces

Published: March 2020

Beneficial plant-growth-promoting bacteria (PGPB) have been reasonably applied to rescue crucial issue for agriculture by salinity soil. Observed most of PGPB was found in endophyte, rhizosphere and soil. Indole acetic acid (IAA)-producing bacteria could naturally stimulate and facilitate plant growth. The knowledge of IAA production and content of bacteria resident in the marine environment has been typically insufficient and limited to date. In recent years, unwarrantable intrusions of sea water have been enlarged in the Mekong River Delta of Vietnam, threatening productive rice fields, local fruits, and cash crops. Therefore, finding PGPB in the coastal regions in the Mekong River Delta as a creative resource for sustainable agriculture is necessary and is a prompt challenge. In this study, IAA-producing bacteria from coastal regions of Ben Tre and Tra Vinh Provinces were isolated and adequately identified. Out of 202 bacterial isolates, 10 isolates showed the possible ability to produce IAA from L-tryptophan. These 10 isolates were objectively evaluated the capacity to produce IAA under 5% (w/v) NaCl in King B and marine broths. The results revealed that IAA production decreased in 5% NaCl, even though bacterial growth increased. These 10 IAA-producing bacteria were classified at the species level, Marinobacter hydrocarbonoclasticus, M. pelagius, M. daepoensis, and Mameliella phaeodactyli by 16S rRNA gene analysis. The most IAA producer in King’s B broth, the isolate C7, was investigated in more detail. The isolate C7 produced the maximum IAA amount (192.2 ± 1.14 µg/ml) under the presence of 20 g/l yeast extract, 2 g/l of L-tryptophan and 1% NaCl. The isolate C7 was able to grow at 1–17% (w/v) NaCl (optimum, 4%), but not in the absence of NaCl, indicating it is a moderate halophilic bacteria. This study highlighted the considerable ability to produce IAA of marine bacteria, which could be thoughtfully considered to use naturally as biofertilizers to promote plant growth in saline intrusion lands.
First report on two ostracod genera  Loxoconcha Sars, 1866 (Loxoconchidae) and Xestoleberis Sars, 1866 (Xestoleberididae) along the coast of Vietam

Published: March 2020

One survey was done with SCUBA diving in Ha Long Bay and Cat Ba Island, Northern Vietnam (December 2013) and another one at Nha Trang Bay Marine Protected Area, Nha Trang city, Central Vietnam and Phu Quoc Marine Protected Area, Kien Giang Province, Southern Vietnam (November 2014). Sixteen species of the genus Loxoconcha and fourteen species of the genus Xestoleberis were found and identified. Eight species of the genus Loxoconcha were identified in group A, three species in group B, two in group C and three unidentified. Meanwhile, twelve species of the genus Xestoleberis were classified in group A and two in group B according to phylogenetic groups. From geographical distribution of the pore groups of the species in two genera Loxoconcha and Xestoleberis showed that the fauna of these genera in Vietnam is close to those of southern part of Japanese Island Arc, i.e., from Amami Island to the Philippines and Australia rather than Japanese Island Arc faunas.

Effects of nano mineral-supplemented diet on sow productivity
Authors: Son Hoang Nghia
Published: March 2020

This study aimed to evaluate the effects of nano mineral-supplemented diet on sow productivity. The data were estimated by several parameters consisting of piglet live ratio at newborn stage and weaning stage, piglet weight at newborn stage and weaning stage, metal content in piglet livers. The results showed that live ratio of newborn piglets in group III was highest (93.44 ± 2.83%) comparing with other groups. However, there was no significant difference of live ratio in piglets at weaning stage between nano mineral-supplemented groups with control. The birth weight of piglets in nano mineral-supplemented groups was similar to control group. The birth weight of piglets in nano mineral-supplemented groups was ranged from 1,361.61 ± 47.37 grams (group II) to 1,410.48 ± 44.28 grams (group I). However, the average weight of weaned pigs in groups III and IV was higher than other groups (6,772.92 ± 105.47 grams and 6,818.87 ± 89.59 grams). Moreover, the amount of Fe, Cu, Zn, Mn in piglet liver from nano mineral-supplemented groups have been found to be lower than those in control group. These results revealed that the supplement of nano minerals for sows promoted the reproductive performance of sows and reduced mineral content in the liver of piglets.

Current athletic administrators are not only charged with overseeing programs that are critical to student-athletes’ athletics success, but must be increasingly aware of resources to also support success in student-athletes’ academic and personal lives.  In turn, this empirical study explored the needs of student-athletes, coaches and administrators pertaining to mental health and wellness, academic success, and athletic performance at the NCAA Division III level.  Implications and recommendations are presented for athletic administrators as they develop programmatic support for millennial student-athletes who experience heightened mental health and wellness challenges during the transition to college.

Published: March 2020

Abstract—Merostachys delicatula, a new species recorded thus far only from the montane Atlantic forest of southern Bahia, is described and illustrated here. Comments on its taxonomy, distribution, habitat, and phenology are presented. Among the narrow-leaved
congeners occurring in Bahia, the new species is most similar to M. leptophylla. It is distinguished by having internodes glabrous to scabrous (vs. glabrous in M. leptophylla); internodes with an infranodal band of trichomes (vs. absent); culm leaf sheaths abaxially scabrous
(vs. glabrous); upper glumes 1.2‐2.1 mm wide (vs. 3.5‐4 mm); anthecia dull (vs. shiny); lemmas 1.5‐2.7 mm wide, abaxially pubescent (vs. ca. 4 mm, glabrous); and paleas 1.2‐2.3 mm wide (vs. ca. 4 mm). We also provide an assessment of the conservation status of the
new species and a geographic distribution map for both species.
Re-evaluation of Some Brazilian Guapira (Nyctaginaceae) Names: A New Species, Nomenclatural Changes and Typifications
Authors: Celestino de Oliveira Chagas Earl , Lucas da Costa-Lima James
Published: March 2020

Abstract—To prepare for a revision of Guapira Aubl. in Brazil, this work proposes nomenclatural changes, typifications, and synonyms. We report twelve more species for the Brazilian flora, including the description of a new species, Guapira candanga,
and resurrection of eleven names previously in synonymy. We rearrange the synonymy of some names, combine seven Pisonia species under Guapira, as G. apolinarii, G. cuneifolia, G. darwinii, G. florida, G. heterophylla,
G. laurifolia, and G. platystemon, and designate lectotypes for four names.
Genome Size Variation Between the Native and Invasive Ranges of Senecio madagascariensis (Asteraceae)
Authors: Dematteis Bruno , Ferrucci María S. , Ortega-Baes Pablo , Coulleri Juan P.
Published: March 2020

Abstract—Invasive species must colonize new habitats away from their native range; therefore, factors affecting plant dispersal play a key role in invasion. The ploidy level and genome size (or Cx value) can affect the dispersal traits, physiology, and ecology of invasive
species over a few generations, generating individuals that can face fluctuating environments, exploit new ones, and compete with native species. Several studies have demonstrated that invasive species tend to have smaller genomes than their noninvasive congeners, which is explained by the
role that the Cx value plays in phenotypic evolution and ecological tolerance. In order to test this hypothesis, we compare the genome size variation in Argentine populations (invasive range) vs. South African populations (native range) of S. madagascariensis. To meet our goals, we
estimated the Cx value of invasive populations collected on field trips, while for native populations we considered available published data. We extracted the bioclimatic variables in order to establish the ecological amplitude in which the genome sizes may be distributed. Our results evidenced
larger genomes in the invasive range than in the native one. Furthermore, we propose that large genomes of the invasive populations could be mainly explained by the founder genotypes effect and the anthropogenic introduction of this species to Argentina. In addition, we demonstrated that genotypes
with big genomes can tolerate different environmental conditions from those of their native range. Therefore, they could present a greater ability for colonizing new environments. The implications and importance of ploidy level in the invasion of S. madagascariensis are discussed.
Categorically Provisional
Authors: Brown Susan
Published: March 2020

Feminist Literary History Balances Commitment to a Different Future, One Better Than the Present with Respect to Gender, with an orientation toward the past, whose ways of knowing it seeks to supersede even as it engages with them. The revision of our cultural past through the lens of gender has, by drawing on past categorizations of authors as female, necessarily invoked problematic paradigms in the service of critique and epistemological change. The relation of the digital humanities (DH) to category work is similarly fraught. I offer here my take on the power and peril of classification based on category making in the pursuit of digital feminist literary history through the Orlando Project, an ongoing experiment in using semantic markup for online scholarship. Orlando is known for its online textbase, published with Cambridge University Press, but the team has produced a number of exploratory interfaces and translations of the material into other forms. Over the course of a quarter century of grappling with “thedigital as difference” (Wernimont and Flanders 430) alongside other feminist projects, I have changed my understanding of classification as my collaborators and I have tried to represent the difference that gender analysis makes when undertaken in a computational environment. I here argue that category work, always vexed, always provisional, is crucial to realizing the potential of DH for representing, analyzing, and fostering difference.
The Form of Black Lives Matter
Authors: Shore Daniel
Published: March 2020

On Friday, 20 January 2017, Inauguration Day for the Forty-Fifth President of the United States, I Spent Several Hours walking around downtown Washington, DC, just north of the National Mall, holding a handmade sign reading “Black Lives Matter.” A day later, the Women's March would pack the city's downtown tight with bodies marching, chanting, and singing in a strange mix of camaraderie and despondency, but on Inauguration Day the streets were unusually quiet. The fear of violence was palpable (and, in the event, fully justified), even as I knew that my whiteness would work as a shield that nonwhite protesters lacked; it was because of this “drastically unequal distribution of bodily vulnerabilities,” as Sarah Ahmed has put it (238), that I carried the “Black Lives Matter” sign in the first place. Over the course of a few hours, the sign provoked a range of responses. A group of attendees greeted me with a “Sieg Heil,” a Nazi salute, and a shout of “white power.” Two men circled behind me to whisper “Blue lives matter” in my ears. But the steady refrain, shouted by dozens of inauguration attendees, was “All lives matter.”

The responses to my “Black Lives Matter” sign were hardly unique to that day. Similar exchanges have unfolded before and since, between other protestors on other streets, in other spaces real and virtual. Taken together, these utterances offer a partial, highly mediated linguistic map of the current political battlefield in the United States and beyond. Through them, factions have taken shape and become legible—become real—to one another and to themselves. In Louis Althusser's famous phrase, they are a part of the current system of representations by which we “live the imaginary relation” to “the real conditions of existence” (223-24) and alter those conditions in the process. Might new digital tools help us understand how these utterances came to serve their peculiar role in our current political moment?
Picture This: The Screenshot's Use in Digital Humanities Scholarship
Authors: Clark Meredith D.
Published: March 2020

When I Consider the Codes and Transformations that Frame Our Approaches to Analyzing Black Culture in the Digital Age, I prefer to focus on the simple rather than the complex. The array of tools and approaches available in the field, which allow us to perform complicated tasks such as parsing binary code to map relations across space and time, offer a number of points of departure. While some of my work has contributed to big-data analyses of social movements containing legions of actors, texts, and artifacts, it is powered by a distinctly analog data-collection process, one that depends on intimate knowledge of the field, the site of inquiry, and the participants. To examine the cultural complexities of social-media-fueled social movements, and the construction of networked communities out of which they grow, I often rely on a rather unsophisticated data-collection tool available to just about anyone with access to a computer screen or a smartphone: the Screenshot.
The Lag: Technology and Fiction in the Twentieth Century
Authors: Manshel Alexander
Published: March 2020

Literary histories of the twentieth century often emphasize how rapid technological innovation spurred writers to reimagine the novel's form and central concerns. This essay investigates that claim, comparing the presence of various information technologies in American fiction with their nonfictional presence in American households. What this comparison reveals is a pronounced lag: a gap in time between when a new technology becomes ubiquitous in the home and when it becomes ubiquitous in the novel. Moreover, the shape of this lag is consistent across multiple technologies, tracing a normative trajectory of fictional representation over time. Whereas more popular and more prestigious novels travel in tandem for much of the twentieth century with respect to their inclusion of technology, the two subfields diverge substantially at the close of the century, as conceptions of literary prestige become increasingly defined by an opposition to technologies of the present.

Smart city approach to educational campuses: case study at University of Limerick, Ireland
Authors: Dolidze Giorgi , Spillane John P
Published: March 2020

Cities are in continuous competition for resources, investment and people, creating a need for constant improvement and development. The smart city concept is an approach to making urban environments better through the usage of technology. The aim is to investigate the application of the smart city concept in a university campus in Ireland. There is a plethora of research on the smart city approach, but not in the context of applying the concept to educationally themed environments. This research defines a framework for doing so and applies this to the University of Limerick campus, located in the west of Ireland. The study identifies existing and planned smart initiatives on campus and analyses the synergy among them. It investigates the inception of such initiatives and the problems and benefits associated with them. The research concludes that a goal-oriented programme helps achieve cohesiveness of efforts and improved results. Such programmes require an initiation from an authority, various groups to manage its aspects, a committee to coordinate the groups and a high degree of commitment from various stakeholders. The results of the research present a more diverse usage of the smart city approach while also showcasing new opportunities for educational institutions.
