Authors: Rane Hari D , GOKHALE NITIN , MORE SAGAR SUBHASH , KASTURE MANISH
Published: August 2020

Nitrogen is the major nutrient plays a key role in the production of rice crop and the lateritic soils are low in available nitrogen content. Accordingly, the field study was carried out in lateritic soils of Konkan (Coastal) region during year (2017 – 2018) to find out the effect of different levels of nitrogen along with silica levels on growth and yield of rice. The major aspect behind taking this kind of research was to see the interaction between the applications of varying levels of nitrogen with the different levels of silica. An experiment was carried out with FRBD design. The nitrogen was given by the Konkan Annapurna Briquettes (KAB) which is the compressed tablet type mixture of the fertilizer which is having major nutrients N, P and K. Silica was applied solely through potassium silicate with the paper packets. There might have been positive response with growth and silica levels also with the rate of application of nitrogen with the increased levels of silica. It was observed that the application of 80 per cent RDN through Konkan Annapurna Briquettes (KAB) with Silica @ 100 kg ha-1 which was applied between four hills was found promising in enhancing the growth and yield of Ratnagiri-24 Cv. in lateritic during Kharif season. It could be concluded that, the application of nutrients in the form of Konkan Annapurna Briquettes along with the application of silica can reduce the recommended dose of fertilizer to the extent of 20 per cent during Kharif season in Konkan region.
Construcción estatal de la cuestión indígena en Chaco (Argentina): Ley de las Comunidades Indígenas de 1987
Authors: Muñoz Roberto
Published: August 2020

Luego de la sanción de la Ley de las Comunidades Indígenas, la provincia del Chaco (Argentina) se convirtió en una de las primeras del país en establecer modificaciones relevantes en el orden legislativo. Estos cambios implicaron la incorporación del componente indígena en las políticas públicas, la aplicación de criterios de definición de la “cuestión indígena” y la creación de entidades gubernamentales específicas para la gestión de esta población. Este artículo tiene por propósito analizar las transformaciones que introdujo la normativa provincial en la forma de definir y abordar a la población indígena y qué características presentaron los mecanismos mediante los cuales el Estado intervino. Según esta propuesta, más allá de estas innovaciones legislativas, el Estado siguió abordando el tema indígena como una cuestión rural y agraria que era necesario contener y delimitar en ese espacio, pese a las migraciones internas que tenían lugar del campo a la ciudad.
Cruzando la división de lo público/ privado: el ejercicio del poder comunal en el bajo mixe en Oaxaca, México
Authors: Salazar Zarco Ana Lilia
Published: August 2020

Este artículo plantea que es posible “despatriarcalizar” el poder y cuestionar la autoridad masculina sobre lo femenino, que es visible en lo público y privado. El sistema de reglas que se reproduce en una comunidad de la sierra mixe en Oaxaca (México), propone este cambio en el ejercicio de poder. Para llegar a esta idea, se llevó a cabo una etnografía (historias y entrevistas a profundidad). Este análisis critica la noción de autoridad (en su sentido etimológico, ‘ayudar a crecer’) y agrega valor desde el servicio (la donación hacia la otra persona). Además, el estudio propone la posibilidad de ejercer poder sin dominación ni verticalidad, lo que sugeriría una ruptura entre la configuración del poder de las formas capitalistas-patriarcales de lo público (operado por el Estado) y de lo privado (operado por el capital). Así mismo, se revisan nociones como lo político y el poder y sus márgenes de ejercicio desde la propuesta de poder comunal indígena.
Los retos de los derechos humanos en sociedades multiculturales
Authors: Mora Navarro Natalia
Published: August 2020

En esta entrevista la docente Natalia Mora entrevista al profesor David Sánchez Rubio quien reflexiona acerca de la diversidad cultural en el contexto latinoamericano. Se exponen ideas de actualidad en relación con los retos que enfrentan las sociedades multiculturales, con propuestas que son relevantes para países como Ecuador. Es importante pensar con sentido crítico los retos a los que se enfrenta la sociedad actual, tales como la falta de sensibilidad hacia los derechos humanos o que las estructuras sobre las que se construye la sociedad actual se rijan por parámetros que limiten espacios de diversidad y pluralidad. Pese al desarrollo de los derechos humanos, aún es necesario recalcar la necesidad de reforzar la idea de dignidad  humana, para que todas las personas puedan existir a plenitud con sus particularidades y diferencias identitarias, sin ser excluidos, marginados o discriminados, ya que la diversidad es una auténtica fortaleza

Keeping the Aged Engaged: A Quantitative Study of Lifelong Learning
Authors: Paydon Steve , Dilenschneider Robert
Published: August 2020

In this study we seek to confirm the findings of a preliminary qualitative study. We first discuss the concept of lifelong learning in Japan and self-determination theory (SDT). Second, using SDT as a framework, we present the findings from a qualitative study. Third, we discuss the findings obtained from a quantitative survey and how they build upon the findings of the qualitative study. Overall, the findings reinforce the notion that the three essential psychological needs in self-determination theory—competence, relatedness, and autonomy—are useful in keeping mature learners engaged in lifelong learning activities.
本研究は、質的予備研究の結果を確認しようとしている。まず、日本での生涯学習の概念と自己決定理論（SDT）について議論する。第二に、フレームワークとしてSDTを使用して、質的研究の結果について説明する。第三に、量的調査から得られた結果と、その結果がどのように質的調査の結果に基づいているかについて説明する。全体として、これらの調査結果は、自己決定理論における3つの本質的な心理的ニーズ（能力、関連性、自律性）が、成熟した学習者が生涯学習活動に参加するのに役立つという概念を補強している。

Isolation and molecular phylogeny of RFT1 gene from upland rice leaves cultivar
Authors: MOHAMMED Sulaıman
Published: August 2020

Rice is a modern short-day plant but equally flower during non-inductive long-day condition due to the possession of second florigen, Rice Flowering Locus T1 (RFT1). RFT1 is an ortholog of Arabidopsis FT gene which triggers flowering induction under long-day (LD) condition. The gene isolation from Malaysian upland rice cv. Wai that induces flowering were reported. Nucleic acids isolation and amplification of the RFT1 were observed, then phylogenetic relationship among other 5 indica and 1 japonica rice were inferred by comparing the gene amino acids sequence data sets using multiple sequence alignment databases. The amplicon quality result indicated that the gene was fully amplified at above 0.5kb, whereas the sequence alignment revealed that the RFT1 gene was partially amplified based on the gaps identified. Among the 6 indica cultivars sequence aligned, they were almost all conserved except on only 12 amino acids. While the cladogram tree result classified the cultivars into three major groups and include Wai under clade that contains both indica and japonica cultivars. This finding concluded that the cultivars are of high evolutionary relationship and well established their molecular relationship. The cultivars relationship provides necessary information for better understanding of molecular evolution and designing scientific breeding system for generation of new rice cultivar.
An easy and reliable method for establishment and maintenance of tissue cultures of Nicotiana tabacum cv TAPM 26
Authors: KAYA Yilmaz , HUYOP Fahrul Zaman
Published: August 2020

In vitro regeneration of Nicotiana tabacum was efficiently achieved using growth regulators combination supplemented into semi-solid MS medium using leaves from 1-month-old plant as explants. The growth regulators used were NAA for auxin (0.0, 1.0, 2.0, and 3.0 mgL-1) and BAP (0.0, 0.5, 1.0, 2.5, and 5.0 mgL-1). The effects of growth regulator combination were assessed based on a number of callus formation, shoots formation and fresh callus weight. The maximum number of callus formation was 100 % at five hormone combination, observed at the fourth week after culture. Maximum number of shoots produced per explant was 21.4 shoots at 1.0 mgL-1 BAP + 3.0 mgL-1 NAA, after 6 weeks of culture. The maximum callus fresh weights were obtained at 0.5 mgL-1 BAP + 1.0 mgL-1 NAA after 6 weeks (9.92 g). The best combination for shoots regeneration of Nicotiana tabacum was 1.0 mgL-1 BAP + 3.0 mgL-1 NAA. And the best combination for heaviest callus production was 0.5 mgL-1 BAP + 1.0 mgL-1 NAA.

Transient Jupiter Co-orbitals from Solar System Sources
Authors: Greenstreet Sarah , Gladman Brett , Ngo Henry
Published: August 2020

We demonstrate dynamical pathways from main-belt asteroid and Centaur orbits to those in co-orbital motion with Jupiter, including the retrograde (inclination i > 90°) state. We estimate that, at any given time, there should be ∼1 km-scale or larger escaped asteroid in a transient direct (prograde) orbit with semimajor axis near that of Jupiter’s (a ≃ a

J
), with proportionally more smaller objects as determined by their size distribution. Most of these objects would be in the horseshoe dynamical state, and are hard to detect due to their moderate eccentricities (spending most of their time beyond 5 au) and longitudes relative to Jupiter being spread nearly all over the sky. We also show that ≈1% of the transient asteroid co-orbital population is on retrograde orbits with Jupiter. This population, like the recently identified asteroid (514107) 2015 BZ509, can spend millions of years with a ≃ a

J
including tens or hundreds of thousands of years formally in the retrograde 1:-1 co-orbital resonance. Escaping near-Earth asteroids (NEAs) are thus likely the precursors of the handful of known high-inclination objects with a ≃ a

J
. We compare the production of Jovian co-orbitals from escaping NEAs with those from incoming Centaurs. We find that temporary direct co-orbitals are likely dominated by Centaur capture, but we only find production of (temporary) retrograde Jovian co-orbitals (including very long-lived ones) from the NEA source. We postulate that the primordial elimination of the inner solar system’s planetesimal population could provide a supply route for a metastable outer solar system reservoir for the high-inclination Centaurs.
A Peculiar Cyclotron Line near 16 keV Detected in the 2015 Outburst of 4U 0115+63?

Published: August 2020

In 2015 October, the Be/X-ray binary 4U 0115+63 underwent a type II outburst, reaching an X-ray luminosity of ∼1038 erg s−1. During the outburst, Nuclear Spectroscopic Telescope Array (NuSTAR) performed two Target of Opportunity observations. Using the broadband spectra from NuSTAR (3–79 keV), we have detected multiple cyclotron lines of the source, i.e., ∼12, 16, 22, and 33/35 keV. Obviously, the 16 keV line is not a harmonic component of the 12 keV line. As described by the phase-dependent equivalent widths of these cyclotron lines, the 16 keV and 12 keV lines are two different fundamental lines. In our work, we apply the two-poles cyclotron line model to the observation, i.e., the two line sets are formed at the same altitude (∼0.2 km over the NS surface) of different magnetic poles, with ∼1.1 × 1012 and 1.4 × 1012 G in two poles, respectively.
Molecular Distributions of the Protostellar Envelope and the Outflow of IRAS 15398–3359: Principal Component Analysis
Authors: Okoda Yuki , Oya Yoko , Sakai Nami , Watanabe Yoshimasa , Yamamoto Satoshi
Published: August 2020

Using the Atacama Large Millimeter/submillimeter Array, we have imaged 15 molecular-line emissions and the dust continuum emission around the Class 0 protostellar source IRAS 15398−3359. The outflow structure is mainly traced by the H2CO (K

a
 = 0 and 1), CCH, and CS emissions. These lines also trace the disk/envelope structure around the protostar. The H2CO (K

a
 = 2 and 3), CH3OH, and SO emissions are concentrated toward the protostar, while the DCN emission is more extended around the protostar. We have performed principal component analysis (PCA) for these distributions on two different scales, the outflow and the disk/envelope structure. For the latter case, the molecular-line distributions are classified into two groups, according to the contribution of the second principal component, one having a compact distribution around the protostar and the other showing a rather extended distribution over the envelope. Moreover, the second principal component value tends to increase as an increasing quantum number of H2CO (K

a
 = 0, 1, 2, and 3), reflecting the excitation condition: the distribution is more compact for higher excitation lines. These results indicate that PCA is effective at extracting the characteristic features of the molecular-line distributions around the protostar in an unbiased way. In addition, we identify four blobs in the outflow structure in the H2CO lines, some of which can also be seen in the CH3OH, CS, CCH, and SO emissions. The gas temperature derived from the H2CO lines ranges from 43–63 K, which suggests shocks due to the local impact of the outflow on clumps of the ambient gas.
Rapid chromosomal evolution in the bush-cricket Gonatoxia helleri Hemp, 2016 (Orthoptera, Phaneropterinae)

Published: August 2020

Gonatoxia helleri Hemp, 2016 is one of the most widespread bush-crickets of the genus Gonatoxia Karsch, 1889 in East Africa. This species with seven large chromosomes (2n♂ = 7) differs from other representatives of the genus Gonatoxia drastically by its reduced chromosome number, the asymmetrical karyotype including karyomorphs rarely found in tettigoniids, as well as in irregularities in the course of meiosis. To better understand the origin of such an exceptional karyotype, chromosomes of 29 specimens from four populations/localities were studied using classical techniques, such as C-banding, silver impregnation, fluorochrome double staining and fluorescence in situ hybridization (FISH) technique with 18S rDNA and (TTAGG)n telomeric probes. FISH showed many 18S rDNA loci as well as interstitial telomeric sequences, where chromosome morphology varied in these components in terms of quantity and distribution. The 18S rDNA loci coincided with active NORs and C-banding patterns. We suggest that a combination of Robertsonian rearrangements and/or multiple common tandem fusions involving the same chromosomes contributed to the formation of this karyotype/karyomorphs. The results are the first step towards a better understanding of chromosomal reorganization and evolution within the genus Gonatoxia. Low chromosome number, together with the incidence of chromosomal polymorphism that is higher in G. helleri than previously reported in bush-crickets, implies that this species can be a valuable new model for cytogenetic and speciation studies. Our findings suggest that chromosomal translocations lead to diversification and speciation in this species and could be the driving force of adaptive radiation.
The effects of rainfall and arthropod abundance on breeding season of insectivorous birds, in a semi-arid neotropical environment

Published: August 2020

Rainfall in tropical semi-arid areas may act as a reliable cue for timing bird reproduction, since it precedes future food supply. With this in mind, we set-up a study to test the reproductive response of insectivorous bird to arthropod abundance and rainfall patterns. Sampling occurred in a seasonally dry Neotropical forest, in north-eastern Brazil, between October, 2015 and October 2016, at 14-day intervals. We used brood patch to assess reproductive periodicity of insectivorous birds (eight species, 475 captures, 121 patch records). We sampled arthropods to quantify abundance, using biomass and number of individuals (1755 individuals, 15 Orders). Rainfall temporal distribution was analyzed using daily precipitation data. We used a cross-correlation function to test for correlation and time-lags between the covariates under study. Both the number of reproductively-active birds and arthropod abundance were higher in time periods close to the rainy season. Increase in arthropod biomass in the aerial stratum preceded the period of greatest rainfall by one (14 days, r = 0.44) to three sampling periods (0.47). In contrast, the highest proportion of individuals with brood patches occurred after the main rainfall peak, with the strongest relationship occurring after two (0.52) to four (0.50) time lags. Finally, the proportion of individuals with brood patches was positively correlated with aerial stratum arthropod biomass when five time lags were considered (0.55). Our results support the hypothesis of a temporal process involving rainfall, arthropods and reproduction of insectivorous birds in the wet/dry tropics. However, rainfall did not appear to act as a cue for the timing of reproduction, since records indicated higher arthropod biomass before the main rainfall peak. At least occasionally in the study area, insectivorous bird reproduction peaks after food abundance.

Mary Ward, une femme jésuite
Authors: Dapsance Marion
Published: August 2020

Mary Ward est une figure peu connue du catholicisme européen. Son nom reste associé aujourd’hui, dans certains pays comme l’Italie, à un réseau d’écoles comparable à celui de Maria Montessori. Ce réseau des « dames anglaises » dont elle est à l’origine est réputé pour ses méthodes pédagogiques destinées à aider chaque enfant à développer au mieux son potentiel humain. Or, la conception de l’enfant – et, plus globalement, de l’être humain – sur laquelle repose cette pédagogie est fondée sur la spiritualité ignatienne de Mary Ward, laquelle s’explique en grande partie par sa vie.
L’Enfer de Dante

Dans La Divine Comédie, Dante propose à son lecteur, sous la forme d’un voyage dans l’au-delà, un véritable pèlerinage intérieur. La première étape passe par L’Enfer. De cette connaissance du mal, des défigurations qu’il fait subir à l’homme intérieur, dépend la suite du chemin. Cet article est le premier d’une série consacrée aux trois volets de l’épopée mystique de Dante.
Une pulsion de mort… pour aider à vivre
Authors: Dethieux Jean-Baptiste
Published: August 2020

Le traitement analytique de M., venu consulter au décours de deux somatisations graves, paraît exemplaire du travail de réintrication faisant suite à la désintrication pulsionnelle, travail rendu possible par la possibilité de convoquer un masochisme gardien de la vie (Rosenberg, 1992). Ainsi, la pulsion de mort n’engage pas la même destructivité selon qu’elle est liée ou non à la libido, soit à la pulsion de vie. L’émergence d’une somatisation viendrait ici comme une possibilité de constituer un objet à combattre, objet précaire, ne survivant pas à la guérison. Donc, se battre… afin que la pulsion de mort – dernier rempart contre la mort elle-même ? – sinon aide à vivre, puisse céder la place à une pulsion à vivre, certes masochiquement.
Le couple pulsion de vie/pulsion de mort à l’œuvre
Authors: Brun Anne
Published: August 2020

Cet article propose d’interroger la dynamique entre pulsion de vie/pulsion de mort à partir d’une approche psychanalytique du processus créateur, centrée sur les processus d’émergence et de transformation des formes sensori-motrices, dans des cliniques de la création. Dans les médiations thérapeutiques, l’émergence de formes relève d’une réactualisation de sensations hallucinées, porteuses de l’histoire des liens premiers à l’objet qui se scénarisent dans la rencontre du médium malléable (matière et analyste) et « sexualisent » la pulsion créative. Loin de dissocier le travail des pulsions de vie et des pulsions de mort, l’analyse du processus créateur à partir de l’émergence de ces formes primaires de symbolisation montre comment un processus de retournement passif/actif permet de donner figure à des expériences agonistiques. Le couple pulsion de vie et pulsion de mort apparaît à l’œuvre dans cette mise en forme d’expériences archaïques qui ouvre sur la dynamique du détruit/créé (Didier Anzieu).

Published: August 2020

This study aims to explore the effectiveness of inquiry learning models inter-vened by the reflective process to promote the critical thinking ability of preserv-ice teachers in terms of cognitive style. This study is a quasi-experimental re-search with one-group pretest posttest design. The research sample involved 24 preservice physics teachers who studied at the Physics Education Department - Mandalika University of Education (Undikma). Cognitive style measurement us-es the Group Embedded Figures Test (GEFT) to identify groups of preservice teachers into the field dependent (FD) or field independent (FI) cognitive style. Measurement of critical thinking ability using test instruments in the form of es-says consisting of 8 test items. Critical thinking ability score is analyzed descrip-tively and statistically, where the normality test and paired t-test was conducted. The results of the study show that as many as 13 preservice teachers are catego-rized into the FD cognitive style and 11 categorized into the FI cognitive style. The average pretest score of the two cognitive style groups (FD and FI) was 0.87 with the criteria of "less critically", and after the implementation of the inquiry learning model intervened by the reflective process, the average posttest score was 16.25 with the criteria of "critically," and n- a gain of 0.64 with the criteria of "moderate." These results indicate that the inquiry learning model intervened by the reflective process is effective to promote critical thinking ability of preservice teachers with FD and FI cognitive styles.

Published: August 2020

Adopting new technologies in Jordanian universities, namely cloud services, represents change in practices that needs to be investigated, as it is expected to face resistance in adoption by faculty members and staff that are used to old practices. A dedicated questionnaire was constructed based on the UTAUT model in order to identify the factors affecting the behavioral intentions leading to use new technologies. Five Jordanian universities participated in this study, and the results showed that there is a high behavioral intention (BI) among staff and faculty members to use cloud services and solutions within their workplace. This research showed that there are factors positively affecting the adoption of cloud services in Jordanian universities, and negative factors have been identified too. University management and staff members needs to be introduced to these factors in order to have better judgement on the future investment and practices of using new technologies.

Published: August 2020

The digitalization of society, changes in the structure of education, and increasingly rapid resources have accelerated the development of an open learning environment. The application of electronic learning and mobile learning raises several new problems such as alienating students from the real world, the difficulty of students focusing on learning goals, giving students opportunities to spend their learning time with entertainment, to the problem of increasing the cognitive load of students. Ubiquitous learning, as a continuation of the evolution of electronic learning and mobile learning, offers more than just the latest educational ideas or methods, where this system can accommodate students and their learning styles by providing adequate information anytime and anywhere based on their characteristics, needs, and desire to improve academic performance and productivity.

This study reports the demonstration of the effectiveness of a mobile education tool (MET) that was co-designed and developed at the College of Business Education (CBE) in Tanzania by a team of teachers, researchers, and a developer using the Design Science Research (DSR) methodology. The demonstration of the CBEMET Prototype as an artifact was done to 30 teachers who had participated in the co-designing of the prototype phase, 3 members of CBE management team and 20 students in Bachelor II degree program as the observers and representative of those who will use the prototype at a later stage. Different sets of questionnaires were administered to the teachers, the members of the management team and the students. The demonstration confirmed that it is easy to access the prototype, share learning contents, and provide education through mobile devices. Nonetheless, teaching materials prepared for testing the prototype were insufficient and thus needed improvement. Furthermore, teachers and observers proposed for more options to the prototype such as the inclusion of timetables, alerts of events like examination dates, and news on innovation activities. The feedback from the participants has thus been considered to reduce errors in the usage of the prototype before its final deployment.
