Pengaruh Couple Prenatal Class Terhadap Kecemasan Ibu Dalam Menghadapi Persalinan Di Klinik Hana Jogonalan Klaten
Authors: Kurniawati Anik , Suwanti Endang
Published: January 2020

The husband is a wife's assistant and often as a decision maker both during pregnancy and childbirth, therefore the husband also needs to get the same information as pregnant women. According to Lutfiatus Sholihah (2004), during pregnancy, the husband must also be invited to prepare to welcome the arrival of the child, because not all husbands are ready to mentally wait for his wife who is in pain, sometimes they even panic and can not calm the wife who was giving birth.Based on a preliminary study conducted that the class of pregnant women is only given to mothers without involving the husband or partner. Preliminary study data also shows that there are still many pregnant women who come to health workers during the fake labor phase. Pregnant women arrive early due to anxiety and fear of facing labor.The purpose of this study was to determine the effect of prenatal class couples on maternal anxiety in facing labor at the Hana Jogonalan Klaten clinic. This type of research is Quasi experiment, with post test design without control group design. The study was conducted at the Klaten Jogna Hanna clinic from May to August 2018.The target population in this study were pregnant women with a minimum gestational age of 36 weeks with a total population of 20 respondents The sampling technique in this study was total sampling. 10 respondents were given classes of pregnant women with husband's assistance and 10 respondents were given classes of ordinary pregnant women, classes of pregnant women were given 2 times in 1 month.The respondent's anxiety state was measured using the Hamilton Rating Scale For Anxiety (HRSA) research instrument. Data analysis was performed by univariate and bivariate analysis using the Spearman Rank test. The results showed there was no effect of couple prenatal class on maternal anxiety with a p value of 0.193 and a correlation coefficient of 0.302.

DIRECTORS’ COMPENSATION. WHAT REALLY MATTERS?
Authors: Acero Isabel , Alcalde Nuria
Published: January 2020

In the current scenario of increasing social inequality, the debate over the compensation received by directors and executives of large listed companies, and its justification, has intensified. Drawing on Agency Theory and Human Capital Theory, a multilevel analytical technique is used in this paper to examine the influence of firm-level variables and director-level variables on the individual compensation of the members of the board. The results obtained for the continental European context (Spain in particular) partially support the Human Capital Theory. Nevertheless, there is no evidence supportive of Agency Theory, as corporate governance mechanisms do not contribute to moderate the compensation of directors and there is no relationship between corporate performance and the compensation of directors. The analyses by subsamples (categories of directors) reveal that non-executive director’s compensation seems to be set for a group of individuals as a whole, depending mainly on firm-level characteristics, whereas executive director compensation is more based on the unique characteristics that a particular executive brings to the board.
On Using Inspiraling Supermassive Binary Black Holes in the PTA Frequency Band as Standard Sirens to Constrain Dark Energy
Authors: Yan Changshuo , Zhao Wen , Lu Youjun
Published: January 2020

Supermassive binary black holes (SMBBHs) in galactic centers may radiate gravitational waves (GW) in the nano-Hertz frequency band, which are expected to be detected by pulsar timing arrays (PTAs) in the near future. GW signals from individual SMBBHs at cosmic distances, if detected by PTAs, are potentially powerful standard sirens that can be used to independently measure distances and thus put constraints on cosmological parameters. In this paper, we investigate the constraint that may be obtained on the equation of state (w) of dark energy by using those SMBBHs, expected to be detected by the PTAs in the Square Kilometre Array (SKA) era. By considering both the currently available SMBBH candidates and mock SMBBHs in the universe resulting from a simple galaxy major merger model, we find that ∼200–3000 SMBBHs with chirp mass >109
M
⊙ are expected to be detected with a signal-to-noise ratio >10 by SKA–PTA with conservative and optimistic settings and they can be used to put a constraint on w to an uncertainty of Δw ∼ 0.02–0.1. If further information on the mass and mass ratio of those SMBBHs can be provided by electromagnetic observations (e.g., chirp mass uncertainty ≲50%), the constraint may be further improved to a ≲0.01 level, as many more SMBBHs will be detected by SKA–PTA with relatively better distance measurements and can be used as the standard sirens.
The Influence of Stellar Contamination on the Interpretation of Near-infrared Transmission Spectra of Sub-Neptune Worlds around M-dwarfs
Authors: Iyer Aishwarya R. , Line Michael R.
Published: January 2020

The impact of unocculted stellar surface heterogeneities in the form of cool spots and hot faculae on the spectrum of a transiting planet has been a daunting problem for the characterization of exoplanet atmospheres. The wavelength-dependent nature of stellar surface heterogeneities imprinting their signatures on planetary transmission spectra are of concern particularly for systems of sub-Neptunes orbiting M-dwarfs. Here we present a systematic exploration of the impact of this spot-contamination on simulated near-infrared transmission spectra of sub-Neptune planets. From our analysis, we find that improper correction for stellar surface heterogeneities on transmission spectra can lead to significant bias when inferring planetary atmospheric properties. However, this bias is negligible for lower fractions of heterogeneities (<1%). Additionally, we find that acquiring a priori knowledge of stellar heterogeneities does not improve precision in constraining planetary parameters if the heterogeneities are appropriately marginalized within a retrieval; however, these are conditional on our confidence of stellar atmospheric models being accurate representations of the true photosphere. In sum, to acquire unbiased constraints when characterizing planetary atmospheres with the James Webb Space Telescope, we recommend performing joint retrievals of both the disk-integrated spectrum of the star and the stellar-contamination-corrected transmission spectrum.
Do the TRAPPIST-1 Planets Have Hydrogen-rich Atmospheres?
Authors: Hori Yasunori , Ogihara Masahiro
Published: January 2020

Recently, transmission spectroscopy in the atmospheres of the TRAPPIST-1 planets revealed flat and featureless absorption spectra, which rule out cloud-free, hydrogen-dominated atmospheres. Earth-sized planets orbiting TRAPPIST-1 likely have either a clear or a cloudy/hazy, hydrogen-poor atmosphere. In this paper, we investigate whether a proposed formation scenario is consistent with expected atmospheric compositions of the TRAPPIST-1 planets. We examine the amount of hydrogen-rich gas that TRAPPIST-1-like planets accreted from the ambient disk until disk dispersal. Since TRAPPIST-1 planets are trapped into a resonant chain, we simulate disk gas accretion onto a migrating TRAPPIST-1-like planet. We find that the amount of accreted hydrogen-rich gas is as small as 10−2 wt% and 0.1 wt% for TRAPPIST-1 b and 1 c, 10−2 wt% for 1 d, 1 wt% for 1 e, a few wt% for 1 f and 1 g and 1 wt% for 1 h, respectively. We also calculate the long-term thermal evolution of TRAPPIST-1-like planets after disk dissipation and estimate the mass loss of their hydrogen-rich atmospheres driven by stellar X-ray and UV irradiation. We find that all the accreted hydrogen-rich atmospheres can be lost via hydrodynamic escape. Therefore, we conclude that TRAPPIST-1 planets should have no primordial hydrogen-rich gases but secondary atmospheres such as a Venus-like one and water vapor, if they currently retain atmospheres.
Drifting Pulsation Structure at the Very Beginning of the 2017 September 10 Limb Flare
Authors: Karlický Marian , Chen Bin , Gary Dale E. , Kašparová Jana , Rybák Jan
Published: January 2020

Drifting pulsation structures (DPSs) are important radio fine structures usually observed at the beginning of eruptive solar flares. It has been suggested that DPSs carry important information on the energy release processes in solar flares. We study DPS observed in an X8.2-class flare on 2017 September 10 in the context of spatial and spectral diagnostics provided by microwave, EUV, and X-ray observations. We describe DPS and its substructures that were observed for the first time. We use a new wavelet technique to reveal characteristic periods in DPS and their frequency bands. Comparing the periods of pulsations found in this DPS with those in previous DPSs, we found new very short periods in the 0.09–0.15 s range. We present Expanded Owens Valley Solar Array images and spectra of microwave sources observed during the DPS. This DPS at its very beginning has pulsations in two frequency bands (1000–1300 MHz and 1600–1800 MHz), which are interconnected by fast drifting bursts. We show that these double-band pulsations started just at the moment when the ejected filament splits apart in a tearing motion at the location where a signature of the flare current sheet later appeared. Using the standard flare model and previous observations of DPSs, we interpret these double-band pulsations as a radio signature of superthermal electrons trapped in the rising magnetic rope and flare arcade at the moment when the flare magnetic reconnection starts. The results are discussed in a scenario with the plasmoid in the rising magnetic rope.

Published: January 2020

The parasitic wasp genus Aphaereta Foerster, 1863, belongs to the large subfamily Alysiinae Leach, 1815 (Hymenoptera: Braconidae) and contains solitary or gregarious endoparasitoids of larvae of cyclorrhaphous Diptera living in decaying organic matter.

A new species, Aphaereta vondelparkensis sp. n. (Braconidae, Alysiinae, Alysiini), from a city park in the centre of Amsterdam (Vondelpark) is described and illustrated. The species was discovered on a so-called taxon expedition, in which experts and citizen scientists collaborate on taxonomic projects. The finding highlights the fact that new animal species can still be discovered today, even in the busiest park of the capital of one of the best studied European countries.
Relationship between meiotic behaviour and fertility in backcross-1 derivatives of the [(Gossypium hirsutum × G. thurberi)2 × G. longicalyx] trispecies hybrid
Authors: Konan N’guessan Olivier , Mergeai Guy
Published: January 2020

Wild cotton species are an important source of desirable genes for genetic improvement of cultivated cottonGossypium hirsutumLinnaeus, 1763. For the success of such an improvement, chromosome pairings and recombinations in hybrids are fundamental. The wild African speciesG. longicalyxHutchinson & Lee, 1958 could be used as donor of the desirable trait of fiber fineness. Twelve BC1 plants obtained from the backcrossing of [(G. hirsutum×G. thurberiTodaro, 1877)2×G. longicalyx] (AhDhD1F1, 2n = 4x = 52) trispecies hybrid (HTL) byG. hirsutum(cv. C2) (AhAhDhDh, 2n = 4x = 52) were investigated for meiotic behaviour and plant fertility. Their chromosome associations varied as follows: (2.5 to 11.5) I + (17 to 22) II + (0.31 to 1.93) III + (0.09 to 1.93) IV + (0 to 0.07) V + (0 to 0.14) VI. Their pollen fertility ranged from 4.67 to 32.10 %. Only four BC1 plants produced a few seeds through self-pollination. The remaining BC1 were totally self-sterile and usually presented the highest number of univalents. All BC1 materials produced BC2 seeds (0.44 to 6.50 seeds per backcross) with the number of seeds negatively correlated with the number of univalents (R2= 0.45, P < 0.05). Most BC1 plants gave significantly finer fiber compared to the cultivatedG. hirsutum. SSR markers showed a segregation of wild alleles among the backcross derivatives and Genomicin situhybridization (GISH) revealed presence of entire chromosomes ofG. longicalyxas well as recombinant chromosomes in the backcross derivatives. The significance and details of these results are presented and the prospects of successfully exploiting these plant materials are discussed.
Longistriata flava (Boletaceae, Basidiomycota) – a new monotypic sequestrate genus and species from Brazilian Atlantic Forest
Authors: Sulzbacher Marcelo A. , Orihara Takamichi , Grebenc Tine , Wartchow Felipe , Smith Matthew E. , Martín María P. , Giachini Admir J. , Baseia Iuri G.
Published: January 2020

A new monotypic sequestrate genus, Longistriata is described based on collections from the Neotropical forest of Atlantic forest in Paraíba, Northeast Brazil – an area known for its high degree of endemism. The striking features of this new fungus are the hypogeous habit, the vivid yellow peridium in mature basidiomes, broadly ellipsoid basidiospores with a distinct wall that is ornamented with longitudinal striations and lageniform cystidia with rounded apices. Phylogenetic analysis, based on LSU and tef-1α regions, showed that the type species, Longistriata flava, is phylogenetically sister to the monotypic sequestrate African genus Mackintoshia in Boletaceae. Together these two species formed the earliest diverging lineage in the subfamily Zangioideae. Longistriata flava is found in nutrient-poor white sand habitats where plants in the genera Coccoloba (Polygonaceae) and Guapira (Nyctaginaceae) are the only potential ectomycorrhizal host symbionts.

Species delimitation analyses suggest cryptic diversity, with six cases reflecting allopatric divergence, and two further cases found in sympatry.
La relation patient-proches-soignants en réanimation : des pratiques discursives « hors cadre » vers une éthique narrative dans la relation de soin
Authors: Herbland Alexandre
Published: January 2020

En réanimation, la relation de soin implique trois acteurs, le patient souvent inconscient, ses proches et l’équipe soignante. Dans ce contexte l’enjeu des soins relationnels à travers l’accompagnement des personnes est indissociable de la visée des soins techniques consacrés à la lutte pour la vie. En dehors du cadre contraint à caractère institutionnel ou médicolégal, des productions discursives écrites « hors cadre » existent qu’elles soient à l’initiative des soignants (journaux de bord, lettres de condoléances) ou des patients et des proches (lettres de remerciements). Elles ajoutent une nouvelle dimension dans les interactions entre les trois acteurs concernés en délimitant un espace commun de liberté, en dehors du temps des soins critiques, pour la narration, l’émotion, le partage. En façonnant la relation de soin ces pratiques permettent de reconsidérer l’éthique des soins relationnels en réanimation.
Quel rapport entre la psychanalyse et la sémiologie ? La réponse de Roland Barthes
Authors: Marciniak-Pinel Magdalena
Published: January 2020

Dans cet article je porte mon attention sur le rapport complexe qu’entretiennent la psychanalyse et la sémiologie dont certains aspects furent thématisés par Roland Barthes. Me référant à ses Œuvres complètes, j’effleurerai dans un premier temps les thèmes du signifiant et de la signification, compris dans une perspective tant sémiologique que psychanalytique. Je propose l’hypothèse que dans le combat barthésien pour une sémiologie nouvelle visant la reconnaissance et la valorisation du signifiant, son approche de la psychanalyse est loin d’être monovalente. Nous le verrons en effet, la psychanalyse est considérée tout autant comme adversaire que comme alliée. Dans un deuxième temps, je montrerai pourquoi il importe pour lui de repenser la problématique du « symbole » et de la « symbolisation » dans la psychanalyse et la sémiologie. Je soulignerai enfin l’importance de la psychanalyse lacanienne pour la réflexion sémiologique de Barthes.
Beau-parent avant de devenir parent : une parentalité « à l’essai » ?
Authors: Vincent Justine
Published: January 2020

Cet article entend analyser, à partir d’entretiens biographiques menés auprès de couples en famille recomposée et ayant eu un enfant ensemble, l’impact de l’expérience de la beau-parentalité pour des nullipares au début de la recomposition, dans la projection de leur propre « devenir parent ». Si la présence des enfants de leur conjoint·e les conduit à endosser des tâches parentales, celles-ci demeurent investies différemment selon les situations et restent sous la médiation des parents, faisant de la beau-parentalité une expérience « pratique » incomplète. Il n’en demeure pas moins qu’elle constitue l’occasion de rationaliser et expliciter les attentes, à l’échelle du couple, quant à l’enfant commun à venir : il s’agit parfois de réajuster la parentalité de l’autre. Les beaux-parents, et plus spécifiquement les belles-mères, manifestent ainsi un sentiment d’ambivalence à l’égard de l’expérience parentale antérieure de leur conjoint, que leur propre entrée en parentalité peut venir renforcer. L’incertitude et le caractère pointillé des rôles beaux-parentaux se confrontent avec le tournant biographique que constitue le passage au statut de primo parent, pour les femmes notamment.
Simmel’s Hidden King - and Ours
Authors: Andrews John A. Y.
Published: January 2020

La métaphore simmelien du « roi clandestin » est l’idée directrice d’un âge historique évoquant des associations narratives qui atteignent des profondeurs afin de décrire la dynamique intrinsèque et les tentions de l’activité humaine qui émergent pour Simmel de la contradiction fondamentale entre la vie comme flux continu et les formes résistantes crées par la vie crées et à travers laquelle elle peut s’exprimer. Cet article élabore d’abord les associations narratives et ensuite les utilise pour explorer le problème clé de l’essai de Simmel – l’antipathie unique que Simmel considère comme caractéristique de la modernité – et enfin propose des suggestions sur la manière dont cette métaphore peut ou pas servir pour lire, un siècle après, des caractéristiques de notre actualité.

Le désir collectif d’être une ville
Authors: Duarte Eduardo
Published: January 2020

La naissance, le développement, la maturation, le sommet et la décadence d'une ville ne peuvent être compris uniquement par ses motivations historiques et sociales. Une ville est l'émergence de l'image complexe d'un désir constitué par l'ensemble conflictuel de volontés distinctes, antagonistes et synchroniques. Cette image totale du désir d'une ville est une création imaginaire qui émerge de peurs, de joies, d'espoirs et de rêves. Ces sentiments projettent le tapis de béton sur les environnements naturels. Le corps d’une ville s’étend sur la nature et modifie cet environnement par la force d’un désir imaginaire. La volonté collective de la ville déplace les anciens centres urbains à d'autres régions qui deviennent le centre du désir. Les vieux centres non désirés tombent en ruines. La ville est alors une collection d'images de souhaits du présent et du passé en perpétuel mouvement.

Published: January 2020

The non-invasive radiofrequency (RF) intervention has been demonstrating to improve anthropometric variables in women. However, the molecular mechanisms involved in this response were not elucidated. This study aimed verify the effect of RF on anthropometric measurements, inflammatory cytokines (interleukin (IL)-1β, IL-1ra, monocyte chemoattractant protein type 1 (MCP-1)) and global histone H4 acetylation levels in the peripheral blood of healthy women. The volunteers were divided in sedentary (SED) and physically active (PA) groups and submitted to the intervention (4 sessions, 1 time per week). Blood samples were collected before (T1), after the first session (T2) and after the last session (T3). The anthropometric measures were checked before and after the intervention. A significant reduction in body mass and adipose mass was observed in the PA group at T3 when compared to T1; while reductions in supra-iliac and abdominal skinfolds and abdominal circumference were found in SED and PA groups after intervention. The PA group presented greater reductions in supra-iliac skinfold and abdominal circumference at T3 when compared to the SED group. The intervention did not alter IL-1β and IL-1ra and global histone H4 acetylation levels in both groups. A significant increase in MCP-1 levels was found at T3 compared to T1 in the SED group. In the PA group, a reduction in MCP-1 levels was observed at T2 compared to T1. However, there was an increase in this marker at T3 compared to T1. Non-invasive RF improved anthropometric measurements with more pronounced effects in the PA and this response might involve the modulation of MCP-1.

Alternatives Fuels: The Present and Future of Containment Systems and Their Impact on the Design and Construction of Ships
Authors: Cadenaro F. , Fort E. , Blackmore L
Published: January 2020

In recent years, driven primarily by SOx emissions regulations, there has been a move towards the adoption of Liquefied Natural Gas (LNG) as a marine fuel. More recent decarbonisation targets, and the emissions regulations that are due to follow, will almost certainly trigger a further move towards other low carbon, carbon neutral and zero carbon fuels. Methanol, ammonia, and hydrogen offer a potential pathway for the decarbonisation of the shipping industry. However, the various physical and thermodynamic properties of such alternative fuels will require new containment systems onboard ships requiring the marine industry to embrace containment technologies used in other industries or, where necessary, develop industry-specific solutions. Shipboard containment systems for diesel fuels are currently physical, based on storage at near ambient temperatures and ambient pressures and for natural gas at high pressure (compressed) or low temperature (cryogenic), or a combination of such. Future containment technologies are likely to also include material and chemical based storage, exploiting chemical processes to hydrogenate or dehydrogenate carriers, in both liquid or solid matrices. This paper provides an overview of alternative fuels and their containment technologies and the implications on ship design and construction.
Can Biofuels Help Provide Clean Propulsion for Shipping, Now and in the Future?
Authors: Lewis C , Bauen A
Published: January 2020

E4tech conducted an important study (in 2018) for the Dutch Biofuels Platform and the Port of Rotterdam, as part of the development of a roadmap for decarbonising shipping in the Netherlands. In particular, biofuels can provide large reductions in GHG and non-GHG emissions, with a range of solutions for decarbonisation in the short and longer term. They offer greater decarbonisation potential compared to fossil alternatives aimed at tackling air quality emissions (e.g. LNG). The biofuels analysed were hydro-treated vegetable oil (HVO – including from waste oils and fats), Fatty acid methyl ester (FAME), straight vegetable oil (SVO), ethanol (both conventional and advanced production processes), bio-methanol, bio-LNG, Fischer-Tropsch diesel (FT-diesel) and Upgraded Pyrolysis Oil (UPO).

The study determined the most attractive biofuel options based on criteria such as GHG reduction potential, readiness of production, cost and compatibility with the current vessel fleet in each shipping sub-sector: deep-sea, short-sea and inland shipping. It also provided recommendation on coordinated interventions from the range of actors in shipping industry that can support the uptake of biofuels, overcoming a range of technical, economic and operational barriers to their use.
Towards Electrification of Ro-Ro Passenger Fleet in the Adriatic Sea
Authors: Percic M , Ancic I , Vladimir N
Published: January 2020

With the recent introduction of new requirements for ships energy efficiency, as well as continuous rise of fuel price, there is a growing interest by many shipyards and shipowners to reduce fuel oil consumption. This is particularly important for ro-ro passenger ships in the Adriatic Sea. Various innovative energy efficient technologies could be implemented for these ships in order to reduce their environmental footprint. In this paper the viability to electrify these ships is analysed. This was done by analysing the energy efficiency of the current fleet, including the estimation of the fuel oil consumption and the analysis of ferry routes in the Adriatic Sea, as well as the number of passengers and vehicles transported. Based on this analysis, it is concluded that the electrification of the ro-ro passenger fleet in the Adriatic Sea could be considered as a viable option in the future.
Case Study: Wind-Assisted Ship Propulsion Performance Prediction, Routing, and Economic Modelling
Authors: van der Kolk N. J. , Bordogna G , Mason J. C. , Desprairies P. , Vrijdag A.
Published: January 2020

In this paper, a vessel model for the performance of wind-assisted ships is combined with a routing tool to assess the fuel savings available from the installation of both one and two Flettner rotors when travelling along a Great Circle Route path. This is combined with an economic analysis to assess commercial viability for these hybrid concepts. The case study is performed in collaboration with DAMEN shipyards, who have provided a design for a wind-assist concept to sail in the Baltic Sea, that, since January 2015, is an Emission Control Area where a sulphur limit content of 0.1 % is enforced on the ship fuels. Results for this case study are presented in terms of fuel savings and payback period analysis, where the reference case is an identical ship sailing without wind propulsors. For the 5,150 dwt general cargo vessel travelling at a speed of 10 knots, average fuel savings of 2.99% were obtained in the Baltic Sea for the single Flettner scenario, and 6.11% for the double Flettner scenario. A discussion of key engineering and design constraints for these ships is included.
A Comparative Assessment of Crew Transfer Vessel Motions Between Inclined and Vertical Boat Landing Arrangements
Authors: Hizir O , Maasch M , Turan O , Day S. , Nicholls I
Published: January 2020

Crew Transfer Vessels (CTVs) are an essential part of operations and maintenance activities for offshore wind farms. CTVs, which are generally multihull vessels transport crew from shore to offshore wind farm sites to carry out the scheduled maintenance and repair activities. CTVs thrust onto turbine structures from the rendered bow and push against the structure creating frictional thrust to prevent the bow from relative motions. This study presents and discusses the results from a set of model experiments and numerical calculations to allow a comparative assessment of a CTV’s landing-manoeuvre performance between inclined and vertical boat landing arrangements. The hydrodynamic performance of a CTV in open water and the “thrust-in” condition using inclined and vertical landing arrangements are presented for different vessel thrust force and different fender properties.

Authors: Tamtama Gabriel Indra Widi , Suryanto Paulus , Suyoto Suyoto
Published: January 2020

English is essential for children because it is an international language that is al-ways used in various fields, both in the world of work, education, economics, and social. One method of learning for children is by playing while learning. Gamification in the field of education is an educational approach to motivate stu-dents to enjoy learning by applying the game design. The purpose of this study is to approach the learning of English, specifically for children in kindergarten schools so that children will be more interested and feel happy to continue learning. The gamification method uses a mobile phone-based application with video games. Gamification in question is an English language recognition game for children with games. The introduction of English includes three categories, namely numbers, pictures, and spelling. The result is a mobile-based application that can be used by children to play the introduction of English with the concept of gamification. With the existence of gamification, the conception of children who were initially afraid to learn English became brave and more confident. The contribution given through this paper is to motivate children's willingness to learn English through other learning methods, namely gamification. Make children feel comfortable and not afraid to learn new things, especially English.

Published: January 2020

Dans les hautes savanes guinéennes du Cameroun, Ximenia americana L. est une espèce ligneuse sujette à une forte pression zoo-anthropique. Elle figure pourtant parmi les espèces locales d’un grand intérêt socio-économique. L’objectif de l’étude a consisté en la caractérisation du drageonnage naturel et de l’induction du drageonnage artificiel. Un inventaire a été réalisé en mars 2011 dans 20 parcelles de forme carrée d’un hectare chacune dans la savane naturelle de Dang pour évaluer la fréquence relative d’arbres adultes qui drageonnent. Un total de 633 pieds de Ximenia americana ont été dénombrés, dont 22 portaient des drageons. Des essais d’induction du drageonnage par simple blessure et par sectionnement complet des racines traçantes ont été menés au cours du mois de mars 2011sur 137 arbres adultes d’âges différents dont 70 % sont multicaules. Dix mois après l’initialisation des essais, il s’avère que le mode d’induction artificielle par sectionnement complet est plus efficace (86,67 %) que l’induction par blessure (60 %). Dans les deux types d’induction, les racines exposées à l’air libre ont présenté un taux de réussite plus élevé que les racines recouvertes de terre. Les drageons induits apparaissent majoritairement au pôle distal de la racine-mère. Cette Olacaceae présente une bonne aptitude au drageonnage artificiel. Cependant durant les dix mois de suivi de cet essai, aucun drageon n’a initié son propre système d’enracinement. Cette technique peu onéreuse pourrait constituer une étape importante dans le processus de domestication de cette plante, si les études complémentaires sur une période d’observation plus longue permettent de préciser la néoformation de racines vigoureuses permettant un affranchissement par rapport à l’arbre-mère et une croissance importante.
Diversité alimentaire et prééminence du riz dans les habitudes de consommation au Cameroun
Authors: Batibonak Sariette , Defo Claudine
Published: January 2020

Le Cameroun dispose d’un potentiel naturel sous-exploité. Des dizaines d’aliments d’origine végétale permettent d’apprécier un pan de l’importance de ses ressources. La richesse de ses forêts et de ses terres est attestée par diverses études. Malgré cette multitude de ressources alimentaires, seule une quinzaine d’entre elles font partie des choix alimentaires des populations. Cependant, depuis des décennies, force est de constater que les populations recourent prioritairement au riz, négligeant ainsi les richesses alimentaires à disposition. Comment comprendre cet enclin à consommer principalement les produits rizicoles ? À travers cet article de réflexion, nous esquissons un paradoxe entre ce potentiel en ressources alimentaires et le choix des populations portées vers la consommation du riz dans un contexte de mutation des habitudes alimentaires. Par une approche anthropologique, la réflexion aboutit à la conclusion selon laquelle les ménages camerounais portent leur dévolu prioritairement sur les produits rizicoles.
Le mouvement de désinvestissement des énergies fossiles : une nouvelle phase de mobilisation pour le climat ?
Authors: Lajarthe Fanny , Zaccai Edwin
Published: January 2020

Le mouvement de désinvestissement des énergies fossiles, né en 2010 aux États-Unis, s’est propagé rapidement dans les universités américaines avant de regrouper d’autres appuis, comme des organisations religieuses, des villes ou des fondations philanthropiques. Dans la mesure où il repose sur le principe d’auto-organisation, il se caractérise par une forte coordination, qui elle-même se traduit par la mise à dispositions d’outils, parmi lesquels un argumentaire à tonalité éthique et économique. L’arrivée récente du mouvement en Europe pose la question des difficultés liées à sa diffusion d’un contexte à un autre. En prenant l’exemple de sa diffusion timide en Belgique, nous illustrons la diversité des contextes nationaux qui conditionne nécessairement les stratégies de ce mouvement.

Software firms plan all development and management activities strategically to provide the best products and solutions to their user. IT professionals are involved in the process of studying the bugs reported and assign severity to make decisions regarding their resolution. To make the task fast and accurate, developers use automatic methods. Herein, the authors have used feature selection-based classification technique to decide about the severity of reported bugs. TF-IDF feature selection method is used to select the informative terms, determining the severity. Based on selected terms the support vector machine and artificial neural network classifiers are used for classification. A number of performance measures have been used to test the performance of classification. The bug reports of Eclipse project for JDT and platform products were collected from Bugzilla. The results show that classifying bugs on the basis of severity can be effectively improved by feature selection-based strategy.

In recent times, paraphrase identification task has got the attention of the research community. The paraphrase is a phrase or sentence that conveys the same information but using different words or syntactic structure. The Microsoft Research Paraphrase Corpus (MSRP) is a well-known openly available paraphrase corpus of the English language. There is no such publicly available paraphrase corpus for any Indian language (as of now). This chapter explains the creation of paraphrase corpus for Hindi, Tamil, Malayalam, and Punjabi languages. This is the first publicly available corpus for any Indian language. It was used in the shared task on detecting paraphrases for Indian languages (DPIL) held in conjunction with Forum for Information Retrieval & Evaluation (FIRE) 2016. The annotation process was performed by a postgraduate student followed by a two-step proofreading by a linguist and a language expert.
Interactive Game-Based Motor Rehabilitation Using Hybrid Sensor Architecture
Authors: Ghosh Ahona , Saha Sriparna
Published: January 2020

Game consoles that use interactive interfaces have drawn users' attention as they reduce the total cost and are user-friendly too. This chapter introduces an interactive game to aid motor rehabilitation applicable to patients belonging to all age groups. In the system, the users receive some audio instructions regarding the action they have to perform next. According to that instruction, the user tries to complete the ‘Fruit-to-Basket' game as soon as possible by dropping all the fruits into the basket. Kinect sensor placed in front of the user detects their motions using skeletons containing three-dimensional coordinates of 20 body joints. The speeds of the movements are detected by the accelerometer. After extracting the required features from skeleton and speed, the use of principal component analysis is proved to be effective for feature space reduction. Then support vector machine is used efficiently to recognize the action. The experimental result indicates that the proposed algorithm is best suited in this domain and a very promising one.

Auto-Scaling in the Cloud Environment
Authors: Rajput Ravindra Kumar Singh , Goyal Dinesh
Published: January 2020

Every software application has its own minimum set of requirements like CPU, storage, memory, networking, and power. These have to be integrated into a specific configuration to allow the smooth functioning of the software application. When data traffic becomes higher than expected, higher resources are required. There may not be enough time to provision new resources manually; in such cases, an auto-scaling system is required for managing these situations. Cloud computing means using data, programs, and other resources pooled in the data center and accessed through the internet instead of the user's computer. In the chapter, the authors discussed some aspects related to cloud computing like cloud workload, load balancing, load balancing algorithms, scaling techniques, and auto-scaling to fulfill cloud workload balancing requirements.
The Pedagogical Possibilities of Critically Examining Gender and Sexuality in Initial Teacher Education Through the Lens of Intersex
Authors: Brömdal Annette , Davis Ian
Published: January 2020

Although pre-service Health and Physical Education (HPE) teachers may be acquainted with media headlines categorizing intersex bodies as “deviant,” “non-biological,” “different,” and/or “non-natural” in their reporting on eligibility testing in women's elite sports, few appear to be familiar with what intersex includes and what these tests were designed to reveal. Drawing on Evan and Rich's advocacy to critically analyse body-policies with strong normative body-pedagogies, this chapter unpacks how athletes marked by this category cannot be understood as separate from the corporeal instructions and ‘authorities' that mark and regulate their bodily representation. The chapter inspires and encourages HPE teachers to take the ‘risk' of engaging students in disruptive practices which explore the inscription of power onto particular bodies and abilities in sports and how they as both pedagogues and members of society are all ethically implicated in these relations of power.
