Soursop is a fruit of great socioeconomic importance for the northeastern region of Brazil. However, the quantitative and qualitative limitation of the water resources of this region has reduced its production. The objective of this study was to evaluate the growth of ‘Morada Nova’ soursop plants irrigated with saline water and subjected to exogenous application of hydrogen peroxide through seed immersion and foliar spray. The study was conducted in plastic pots adapted as lysimeters, using a eutrophic Regolithic Neosol with sandy loam texture under greenhouse conditions. Treatments were distributed in randomized blocks, in a 4 x 4 factorial arrangement, corresponding to four levels of irrigation water electrical conductivity – ECw (0.7; 1.7; 2.7 and 3.7 dS m-1) and four concentrations of hydrogen peroxide – H2O2 (0, 25, 50 and 75 µM), with three replicates and one plant per plot. Foliar applications of H2O2 began 15 days after transplanting (DAT) and were carried out every 15 days at 17:00 h, after the sunset, by manually spraying the H2O2 solutions with a sprayer in such a way to completely wet the leaves (spraying the abaxial and adaxial faces). Treatment effects were evaluated based on plant height (PH), stem diameter (SD), number of leaves (NL) and leaf area (LA) at 60 and 90 DAT, and dry phytomass of leaves (LDP), stem (SDP), roots (RDP) and total (TDP) and leaf succulence (LS) at 90 DAT. Irrigation using water with estimated ECw of 1.55 dS m-1 caused acceptable mean reduction of 10% in soursop growth. Increasing concentrations of hydrogen peroxide did not attenuate the effects of salinity on plant height and leaf area during the vegetative stage. Hydrogen peroxide concentration of 20 µM led to higher leaf succulence in soursop plants.

Papaya (Carica papaya L.) is one of the main horticultural crops of many tropical and subtropical regions. The fruit is sold either as a fresh product or processed into drinks, jams, candies, dried and crystallized fruit, while the enzyme papain is used for medicinal purposes. Papaya fruits have high vitamins A and C contents, as well as are good sources of calcium. Brazil is one of the most important producers and exporters of papaya in the world; in 2016 c.a., 1,424,650 tons of papaya was produced in 30,372 hectares of the territory. Optimum light absorption and utilization by the canopy are important factors for maximizing papaya crop growth and productivity. Thus, knowing how papaya responds to light is important to develop management strategies to optimize fruit yield and quality. This short review aims to present the current research knowledge related to the effects of light intensity on the photosynthetic processes and growth of papaya. We demonstrate that photosynthetically active radiation (PAR) greatly affects the physiology of papaya. Understanding the interaction between light and physiological processes is extremely important for a sustainable profitable production under either greenhouse or field conditions. By using improved light science-based management, growers may optimize photosynthetic carbon assimilation and increase papaya yield and fruit quality
Effect of PVP concentration on prepared PEI membranes for potential use on water treatment: effect of additive on membranes prepared for water treatment
Authors: Mutlu Salmanli Öykü , Güneş Durak Sevgi , Türkoğlu Demirkol Güler , Tüfekci Neşe
Published: June 2019

In this work, a series of polyetherimide (PEI) flat sheet membranes were produced with different concentrations of polyvinylpyrrolidone (PVP) addition via the phase inversion method. The effects of additions on membrane morphology and performance were investigated. Synthesized membrane had the properties of ultrafiltration membrane. Although PEI is not widely used for water treatment, in this study, the ferrous iron removal rate was investigated and good results were obtained. Through the membrane production experiments, the PEI content was 22 wt%. PVP was added as a pore-forming agent with concentrations of 2, 4 and 8 wt%. N-methyl-2-pyrrolidone (NMP) was used as solvent. Distilled water was used for the coagulation bath. After production, all membranes were characterized by using contact angle, permeability, porosity, and scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT/IR) analyses. With the increasing doses of PVP addition, the permeability of the PEI membranes produced in this study increased, while porosity results were changeable. The permeability was 23 L/m2h bar for the membrane with 2 wt% PVP content, while the permeability for the membrane with 8 wt% PVP content was 32 L/m2h bar. Contact angles increased with PVP addition to PEI membranes. With the increasing PVP concentration, the finger-like pores and the pores located in the sub-layer expanded.
Assessment of the adsorption kinetics, equilibrium and thermodynamic for Pb(II) removal using a hybrid adsorbent, eggshell and sericite, in aqueous solution
Authors: Choi Hee-Jeong
Published: June 2019

Hybrid adsorbents (ES) were prepared with mixing of eggshell and sericite as binders, and Pb(II) was removed from aqueous solutions. Sericite has the advantage of not only serving as a binder for hybrid adsorbent but also having a negative charge on the surface to improve the removal efficiency of heavy metals. Various parameters affecting the removal of Pb(II) from aqueous solutions were investigated using the optimal conditions derived. In addition, adsorption kinetics, adsorption isotherms and thermodynamic analyses were performed using the experimental results of each parameter. The ES had a more specific surface area and porosity than sericite or eggshell and contained a large number of OH groups favoring heavy metal adsorption. As a result of the adsorption of Pb(II) using the ES, the adsorption process was physical and suitable for the Freundlich isotherm. In addition, the adsorption process of Pb(II) by the ES was a spontaneous endothermic reaction. The ES can quickly reach the adsorption equilibrium and strong adsorption strength. In addition, the CaOH contained in the ES can neutralize the pH of wastewater, and it is possible to treat heavy metal ions in industrial wastewater and acid mine wastewater without controlling the pH. ES adsorbents using waste eggshells are very economic because they recycle what would otherwise be waste and have great significance in terms of resource reuse.
An Assessment of Green Computing Awareness and Adoption in Higher Education Institutions in Zambia: A Case of ZCAS
Authors: Mbewe Serah Beza
Published: June 2019

As the use of Information and Communication Technologies (ICTs) increases in Zambia, there is a general concern about whether the use and eventual disposal of ICT hardware will have minimal impact on the environment. The grooming or modification of behavior of users for the future generation takes place in educational institutions. This paper therefore explored the level of use of ICTs in Higher Educational Institutions (HEIs) with regard to the awareness and adoption of green computing in these institutions. The results indicated that though there is a high level of use in the HEIs, the level of green computing awareness was simply moderate and the level of green computing adoption was low. Therefore, there is need for HEIs, the IT community and the legislative bodies to do more in introducing practices that will promote eco-friendly use and disposal of ICTs in Zambia.

Authors: Bonghanoy Guillermo Baluyot , Sagpang Alben P. , Alejan Jr. Ronnie A. , Rellon Louie Resti
Published: June 2019

This paper was an attempt to redesign the current professional development training for Mathematics teachers in the Philippines. Mathematics teachers claimed that most training and seminars they attended ignored their local work context; was routinely and was hardly applicable to their classroom milieu. By utilizing the transformative professional development training, the teachers identified the classroom issues that had confronted them; restructured their useful pedagogical ideas and instructional plans and materials; implemented these in their classrooms; and shared their reflections on the new teaching experiences. Qualitative data were gathered from focus group discussions and key informant interviews. University researchers (3), secondary Mathematics teachers (28), and students (250) from four rural public schools in the Hamiguitan Range participated. The teachers and students revealed that their lack of self and environmental understanding were the prevalent issues that led to critical behavior in Mathematical cognition and learning. By applying the transformative education in the classroom, promising results like better teacher performance, improved students' interest, and maximized student participation were evident. This transformative professional development training adequately responded to the teachers' work needs and was recommended to other areas of learning.

O papel dos estilos parentais, do bem-estar subjetivo dos pais e da educação pré-escolar no bem-estar subjetivo da criança
Authors: Guerreiro Ana Marlene , Vieira Luís Sérgio
Published: June 2019

O principal objetivo do presente estudo foi explorar o papel dos estilos parentais e do bem-estar subjetivo dos pais no bem-estar subjetivo da criança em idade pré-escolar. A estas variáveis, associamos outras relacionadas com o tempo e as atividades desenvolvidas na educação pré-escolar. Os resultados obtidos revelam uma associação entre níveis de bem-estar subjetivo das crianças e o dos seus pais, a que se associam influências, quer do estilo educativo parental quer da participação da criança na educação pré-escolar. Embora os resultados sugiram que os estilos parentais não desempenham um papel uniforme nas diversas dimensões do bem-estar subjetivo da criança, os mesmos resultados salientam a importância das práticas educativas do estilo democrático na promoção do bem-estar, satisfação e desenvolvimento da criança.

Inter-row cultivation - an agro-technical measure for increasing soybean yield
Authors: Djukic Vojin , Miladinov Zlatica , Dozet Gordana , Balesevic-Tubic Svetlana , Miladinovic Jegor , Randjelovic Predrag , Ceran Marina
Published: June 2019

In order to examine the influence of inter-row cultivation on the soybean
yield, a trial was set up in the Agricultural School in Backa Topola from
2015 to 2017. Three soybean varieties were selected at the Institute of
Field and Vegetable Crops in Novi Sad. Galina, Sava and Rubin were used. The
trials included the different number of inter-row cultivations: control -
without inter-row cultivation, one inter-row cultivation, two and three
inter-row cultivations of soybean crops. Obtained results showed that an
average yield of soybean increased with an increase in the number of
inter-row cultivations during the soybean vegetation period. With one
inter-row cultivation, the yield increase was 5.33%, with two inter-row
cultivations - 7.10% and with three cultivations - 7.33%. In the years with
a lower precipitation, the influence of intra-row cultivation was much more
effective. In 2017, the increase ranged from 10.33% to 13.62%, and in 2016
from 3.09% to 4.27%. Yield was increased due to reduced evapotranspiration
of soil moisture as well as prevention of descending of water into deeper
layers. During summer, this allowed better water conservation in the soil
for critical periods, and also increased the activity of microorganisms as
well as more intensive mineralization of organic matter, which ultimately
influenced the yield.
1399-P: The Accumulative Impact of Insulin Sensitivity throughout Pregnancy on Neonatal Fatness
Authors: LIMA RODRIGO ANTUNES , VAN POPPEL MIREILLE , SIMMONS DAVID , DESOYE GERNOT ,   DALI CORE INVESTIGATOR GROUP
Published: June 2019

Aim: To evaluate the direct and indirect associations between insulin sensitivity during pregnancy and neonatal fatness.

Methods: This is a longitudinal, secondary analysis of the DALI study which was a multicenter study conducted in nine European countries. Pregnant women with a pre-pregnancy body mass index (BMI) of ≥29 kg/m2, <20 weeks of gestation, a singleton pregnancy, and aged ≥18 years were invited to participate. Women diagnosed with early gestational diabetes were excluded. Neonatal fatness was estimated by the sum of triceps, subscapular, supra iliac and quadriceps skinfolds. Maternal insulin sensitivity (HOMA), fasting glucose, triglycerides (TG) and free fatty acids (FFA) were measured three times during pregnancy (13-20, 24-28, and 35-37 weeks of gestation). Structured equation modelling was performed to evaluate the direct and indirect relationship between variables of interest. Analysis was adjusted for maternal ethnicity, maternal education, maternal age, gestational age and neonatal age and results were presented in standard deviations (SD).

Results: In total, 701 mother-infant pairs (51.0% boys) were included. Neonatal girls exhibited higher sum of skinfolds compared to boys (20.5 mm [±5.5] vs. 21.6 mm [±5.3]; p=0.03). HOMA at 13-20 weeks but not at 24-28 or 35-37 weeks was associated with neonatal fatness. This association was mediated through Glucose13-20weeks -> Glucose24-28weeks -> Glucose35-37weeks (0.599 SD for boys and 0.467 SD for girls) and TG13-20weeks -> TG24-28weeks -> TG35-37weeks (0.464 SD for boys and 0.497 SD for girls). The pathway with FFA did not mediate the association between HOMA and neonatal fatness.

Conclusions: Maternal health profile in the first trimester of pregnancy plays an important role in neonatal body fatness, since insulin sensitivity was associated with neonatal fatness via increases in HOMA-Index, glucose and triglycerides throughout pregnancy.

455-P: Levels of Plasma Prekallikrein Predict Myocardial Infarction in Non-Hispanic White Participants of the Veterans Affairs Diabetes Trial (VADT)
Authors: HUNT KELLY J. , JAFFA MIRAN A. , SOHN MIMI , LOPES-VIRELLA MARIA F. , JAFFA AYAD A. ,   VADT INVESTIGATORS
Published: June 2019

We hypothesize in diabetes that augmented activity of the plasma kallikrein-kinin system reflect and contribute to vascular damage and inflammations. Our objective was to determine the role of plasma PK as a predictor of cardiovascular events in type 2 diabetes in the VADT cohort. Levels of plasma total prekallikrein (PK) were measured in 604 VADT patients, a median of 1.5 years after entry into the study. Participants were followed an average of 4.1 years. Hazard ratios (HRs) for CV endpoints in relation to PK tertiles and having a non-zero versus zero value for plasma active kallikrein (PAK) were calculated by Cox proportional hazard models. During follow-up, 4.9% had an MI and 7.4% had an MI or cardiovascular death. Because there was evidence that minority status modified the associations between PK and outcomes of interest, but there was very limited power in minorities, results are presented in the total population adjusting for minority status and limited to the non-Hispanic white (NHW) population (Table). After adjustments by conventional risk factors, in NHW individuals the hazard ratio comparing the middle to lowest tertile of PK levels was 3.94 (95% CI: 1.09, 14.2) for MI and 3.45 (95% CI: 1.25, 9.48) for MI combined with cardiovascular death. Our study indicates that plasma PK levels predict MI and cardiovascular death in NHW patients with type 2 diabetes.

Quiste gigante mucinoso de ovario, reporte de un caso
Authors: Pérez Arévalo Eddie Orlando , Romero Velasco Guzmán Ernesto , Matías Domínguez Giioconda Yalile
Published: June 2019

El cistoadenoma es un tumor quístico multilocular, de superficie externa, lisa y abollonada. Al corte se observan numerosas cavidades con un contenido mucinoso filante y una superficie interior lisa. Se observa en mujeres jóvenes, en quienes los cistoadenomas mucinosos pueden llegar a ser muy voluminosos (mayor a 20 cm). Se presenta el caso de una paciente de 47 años, con una tumoración abdómino-pélvica dolorosa de aproximadamente 30 cm, de diámetro en quien se realizó laparotomía exploradora, encontrándose la presencia de un tumor gigante de ovario derecho (cistoadenoma mucinoso benigno) y en ovario izquierdo (teratoma maduro). Se enfatiza que el diagnóstico diferencial de este tumor no es el embarazo sino otras neoplasias intrabdominales y pélvicas. El diagnóstico de un tumor mucinoso de bajo potencial maligno es difícil de realizar; se basa en los hallazgos de laboratorio, marcadores tumorales, ecografía y tomografía computarizada de abdomen y pelvis. El tratamiento recomendado en mujeres jóvenes sin paridad cumplida, es mantener la fertilidad justificándose la preservación del útero y anexo contralateral. Cuando el tumor es bilateral y en caso de pacientes mayores, con paridad cumplida, la histerectomía total más salpingo-ooforectomía bilateral, es lo indicado debido al riesgo de recurrencias.
Designing and Developing Videos for Online Learning: A Seven-Principle Model
Authors: Ou Chaohua , Joyner David A. , Goel Ashok K
Published: June 2019

Despite the ubiquitous use of instructional videos in both formal and informal learning settings, questions remain largely unanswered on how to design and develop video lessons that are often used as the primary method for delivering instruction in online courses. In this study, we experimented with a model of seven principles drawn from instructional design theories for designing and developing video lessons for an online graduate course. Feedback was collected from students through surveys on their perceptions of the effectiveness of the video lessons and the overall course quality for eight semesters. This paper shares the instructors’ experience on the design and development of the video lessons as well as the survey findings. Implications of the findings for instructional design and future research are also discussed.

Aspectos como intermediación y cohesión territorial, escala humana y gobernanza, y su topología de cortas distancias y de proximidad, refuerzan la idea de la ciudad intermedia como un nuevo paradigma en el proceso de urbanización mundial, y como elemento clave en la implementación a escala local de la Agenda 2030.
Las cooperativas de enseñanza: Un emprendimiento basado en el liderazgo y formación continua docente
Authors: López Belmonte Jesús , López Núñez Juan Antonio , Fuentes Cabrera Arturo
Published: June 2019

Las cooperativas de enseñanza son entidades educativas de carácter social que agrupan a un conjunto de miembros, unidos bajo las mismas necesidades, que persiguen la creación y mantenimiento de puestos laborales en tiempos de recesión económica. Pretenden ofrecer un servicio innovador, eficaz y de calidad basado en el liderazgo y formación continua de los profesionales de este tipo de centros escolares. El objetivo del presente estudio se centra en conocer la vertiente empresarial, formativa y de liderazgo del docente cooperativista de la Ciudad Autónoma de Ceuta. Para ello se ha optado por un método cuantitativo de tipo descriptivo, empleando un cuestionario ad hoc para la recogida de datos en una muestra de 68 docentes-socios pertenecientes a las 3 cooperativas de enseñanza de dicha ciudad. En base a los resultados, se obtiene una dominancia del género femenino y una edad avanzada entre los docentes-socios de las cooperativas analizadas. Estos profesionales conocen las peculiaridades que presentan estas entidades y aunque confían en la inversión realizada, reflejan carencias burocráticas para la gestión cooperativa. En cuanto al liderazgo, se decantan conocedores de tal fenómeno y le otorgan gran relevancia. Pero, en el plano formativo, presentan deficientes conocimientos empresariales y aunque consideran que la formación continua es importante, la mayoría no suele efectuar más de 2 cursos al año. Se concluye que estos profesionales conforman un perfil femenino de edad avanzada que confía en el liderazgo como fenómeno para dinamizar a la entidad pero no disponen de los conocimientos necesarios para administrar con éxito este tipo de centros educativos, requiriendo de una formación especializada en el ámbito empresarial.

Published: June 2019

La influencia de la tecnología es una realidad innegable en todos los ámbitos de nuestra vida, por ello es fundamental el desarrollo de la Competencia Digital en la formación de postgrado de los futuros profesionales de la educación. Mucho se ha escrito en los últimos años sobre la formación docente en el uso de las tecnologías, y del análisis de los resultados obtenidos en investigaciones previas se constatan limitaciones en la formación específica en TIC recibida en los grados de educación en general, así como la tendencia al desarrollo de esta competencia desde una perspectiva transversal. Bajo esas premisas, en estas líneas se pretende describir y analizar una experiencia de aula basada en la introducción de las TIC de forma transversal en la asignatura de Procesos y Contextos Educativos del Máster de Profesor/a de Educación Secundaria de la Universitat de València. Los participantes fueron 42 estudiantes, 25 hombres (58%) y 18 mujeres (42%), que han cumplimentado un cuestionario de Google elaborado ad hoc. Sus resultados indican una valoración positiva del alumnado y el desarrollo de la Competencia Digital Docente. También se desprende la posibilidad de desarrollar, transversalmente, la Competencia Digital Docente en cualquier asignatura de los planes de estudios, y la importancia de su desarrollo desde la formación del profesorado, con el objetivo de favorecer la implementación de buenas prácticas en su futuro profesional.

Authors: Franko Alenka , Goricar Katja , Kovac Viljem , Dodic-Fikfak Metoda , Dolzan Vita
Published: June 2019

Background

This study aimed to investigate the association between NLRP3 rs35829419 and CARD8 rs2043211 polymorphisms and the risk of developing pleural plaques, asbestosis, and malignant mesothelioma (MM), and to study the influence of the interactions between polymorphisms and asbestos exposure on the risk of developing these diseases.

Methods

The case-control study included 416 subjects with pleural plaques, 160 patients with asbestosis, 154 subjects with MM and 149 subjects with no asbestos disease. The NLRP3 rs35829419 and CARD8 rs2043211 polymorphisms were determined using real-time PCR-based methods. In the statistical analysis, standard descriptive statistics was followed by univariate and multivariate logistic regression modelling.

Results

Asbestos exposure (medium and high vs low) was associated with the risk for each studied asbestos-related disease. An increased risk of pleural plaques was found for CARD8 rs2043211 AT + TT genotypes (OR = 1.48, 95% CI 1.01–2.16, p = 0.042). When the analysis was performed for MM patients as cases, and pleural plaques patients as controls, a decreased MM risk was observed for carriers of CARD8 rs2043211 TT genotype (OR = 0.52, 95% CI 0.27–1.00, p = 0.049). The interactions between NLRP3 rs35829419 and CARD8 rs2043211 genotypes did not influence the risk of any asbestos-related disease. However, when testing interactions with asbestos exposure, a decreased risk of asbestosis was found for NLRP3 CA+AA genotypes (OR = 0.09, 95% CI 0.01–0.60, p = 0.014).

Conclusions

The results of our study suggest that NLRP3 and CARD8 polymorphisms could affect the risk of asbestos-related diseases.
L’écriture de l’article scientifique et ses premières traductions
Authors: Banks David
Published: June 2019

Je pense que prendre en considération le développement historique du langage peut nous aider à comprendre son fonctionnement actuel. Par conséquent je vais étudier un échantillon des premiers exemples de la traduction d’articles savants entre deux langues vernaculaires. Le premier périodique savant est le Journal des Sçavans, paru à Paris le 5 janvier 1665. Deux mois plus tard, le 6 mars 1665, les Philosophical Transactions parurent à Londres. Le Journal des Sçavans était rédigé par Denis de Sallo, à l’instigation de Colbert, dont l’objectif était le contrôle de la connaissance nouvelle et son utilisation pour célébrer la gloire de Louis XIV. La France était totalement stable et elle était le centre économique et culturel de l’Europe. Les Philosophical Transactions furent lancés comme une entreprise privée par Henry Oldenburg, un des secrétaires de la Royal Society, comme moyen d’augmenter ses revenus. L’Angleterre venait de traverser un demi-siècle parmi les plus chaotiques de son histoire, mais, à ce moment-là elle se confortait dans l’espoir retrouvé de la Restauration de la monarchie. Le Journal des Sçavans traitait toutes les disciplines de la nouvelle connaissance, y compris la théologie, le droit et l’histoire, et comportait principalement des recensements de livres. Les Philosophical Transactions se restreignaient aux sciences et à la technologie, et se basaient sur le courrier de H. Oldenburg. Son courrier était volumineux car il était au centre d’un réseau de correspondance scientifique. Le premier numéro des Philosophical Transactions comporte la traduction d’un item paru dans le premier numéro du Journal des Sçavans. Cela constitue alors la toute première traduction d’un article savant d’une langue vernaculaire vers une autre. Une étude des traits linguistiques (notamment la thématisation et les types de procès) de ces deux textes démontre que H. Oldenburg suivit de près le texte français, bien qu’il simplifiât son organisation afin de le rendre plus clair. Le Journal des Sçavans fut supprimé après 13 semaines, mais fut ressuscité au début de l’année suivante avec l’Abbé Bignon comme rédacteur. Le numéro du 11 janvier 1666 comporte la traduction d’un item paru aux Philosophical Transactions le 8 mai 1665. Le texte français le présente comme étant un résumé, mais il s’agit plutôt de la traduction d’extraits choisis que d’un résumé proprement dit. L’étude des traits linguistiques fait ressortir les différences entre les deux textes. Etudier ces textes s’avère fascinant en soi. Mis à part leur intérêt propre, il faut souligner le fait qu’ils étaient les premières tentatives de traduire des articles savants. Par conséquent, on peut considérer que l’évolution de la traduction de l’article savant commence ici.
Semantic prosody and semantic preference in multi-word terms
Authors: Cabezas-García Melania , Faber Pamela
Published: June 2019

Multi-word terms (MWTs), in the form of noun compounds (NCs), are frequently used in specialized texts (Nakov 2013). They consist of juxtaposed terms with underlying semantic structures that limit the combination of arguments (Pinker 1989). However, NCs formed by more than two terms have received little attention. This study focused on English and Spanish three-term endocentric NCs used in Coastal Engineering. To explore the presence of semantic preference and semantic prosody in these MWTs, a set of terms was extracted from a Coastal Engineering corpus. The structure of the MWTs was disambiguated and the semantic relations between their components were specified. Verb paraphrases were also elicited from field experts and the web, and then semantically analyzed. The results showed that semantic preference and semantic prosody play an important role in the formation of MWTs and should be taken into account when rendering a text into another language.
Revised definition/outline of the Kheis Terrane along the western margin of the Kaapvaal Craton and lithostratigraphy of the newly proposed Keis Supergroup
Authors: van Niekerk H.S. , Beukes N.J.
Published: June 2019

The Kheis Province is situated between the Namaqua-Natal Province and the western margin of the Kaapvaal Craton in the Northern Cape Province of South Africa. It has been described as a thin-skinned fold and thrust belt formed between 1800 and 1700 Ma. The lithostratigraphic subdivision of the rock units comprising the Kheis Province has been a source of much controversy. From detailed study of aerial photography and satellite imagery, as well as field-based studies, the outcrop patterns in the Kheis Province and Kaaien Terrane were reinterpreted and a new stratigraphic subdivision is outlined here. It is proposed that the structural Kaaien Terrane and Kheis Province should be combined into the Kheis Terrane and that the rocks occurring in the Kheis Terrane should be grouped together to form the new Keis supergroup, with the basal metaconglomerate of the Mapedi/Gamagara Formation recognised as the regional unconformity between the Keis supergroup and the underlying rocks of the Transvaal Supergroup in the Griqualand West area. The Keis supergroup is subdivided from the base upwards into the Elim-, Olifantshoek-, Groblershoop- and Wilgenhoutsdrif groups. The basal Elim group is composed of the Mapedi/Gamagara- and Lucknow formations. It is overlain with a regional erosional unconformity by the Olifantshoek group, which is made up of the Neylan-, Hartley-, Volop- and Top Dog formations. The Olifantshoek group is conformably overlain by the Groblershoop group which is comprised of three upward coarsening successions:the Faanshoek- and Faansgeluk formations,the Maraisdraai- and Vuilnek formations andthe Opwag- and Skurweberg formations.

The Groblershoop group is in turn erosively overlain by the rocks of the Wilgenhoutsdrif Group, which include the basal erosive Groot Drink formation which is overlain by the Zonderhuis- and Leerkrans formations. The lithologies of the Keis supergroup are in faulted contact with the rocks of the younger Areachap Group of the ~1200 Ma Namaqua-Natal Metamorphic Province.

Authors: Fathira Vina , Utami Silvia
Published: June 2019

This research was based on students� difficulties in understanding the concept of politeness and gender. Advertisement can be one of the alternative techniques to improve students� understanding on the concept of politeness and gender. This study aims at improving students� understanding of politeness and gender and finding the factors influencing the improvement. This Classroom Action Research involved ten third-year-students at STIBA Persada Bunda Pekanbaru. The data collection techniques used were tests, fieldnotes, observation, and interview. The results showed that students� understanding of politeness and gender significantly improved after applying advertisements in the teaching and learning process in which the students� understanding which were at the low level category increases to the good level category. Some factors affecting the students� improvement were students� active participation in obtaining information and students� enthusiasm during the learning process. In conclusion, the implementation of advertisements can improve students� understanding of politeness and gender concepts.
PRAGMATIC TRANSFER IN APOLOGY EMPLOYED BY ENGLISH EDUCATION STUDENTS OF ISLAMIC STATE UNIVERSITY (UIN) RADEN FATAH
Authors: Eliza Tiara
Published: June 2019

This study intends to find out and to describe apology strategies made by the sixth and eighth semester students of English Education Study Program of Islamic State University (UIN) Raden Fatah Palembang, and to explain how the pragmatic transfer interferes the apology strategies. This study used a qualitative descriptive design. Written discourse completion tasks and observation by doing a role play were used as the instruments to obtain the data. There were 66 students selected as the subjects of study. The data obtained were analyzed based on the classification of apology strategy proposed by Olshtain and Cohen (1983). As result, it was found that there were five apology strategies made by the students, for example, using the word sorry to express regret was considered the most frequently used strategy. Then, the result also showed that the speakers who have low social status tend to use polite strategy in all levels of social relationships (strangers and acquaintances). For the speakers who have high social status and equal tend to use less polite and casual expressions, respectively. Moreover, some students use some pragmatic transfers in expressing apology strategies influenced by their L1 (mother tongue) or L2 (Indonesian) culture.
THE INFLUENCE OF INDONESIAN PROSODIC FEATURES ON ENGLISH WORD STRESS PRODUCTION
Authors: Widagsa Rudha , Wiyanah Sri , Wahyuni Primasari
Published: June 2019

Generally, word stress tends to be ignored and is not considered a serious problem in Indonesian EFL; most teachers only focus on lexical and grammatical aspects of English. In fact, the prosodic features existing in English greatly affect meaning. This research, therefore, is intended to find out how Indonesian Learners of English (ILE) produce the English word stress. The stressed syllables were identified by using the highest pitch in each word. This research involved 20 respondents whose mother tongue is Indonesian. PRAAT software was applied to analyze the recordings, including measuring the pitch of each word. Word stress is indicated by the highest pitch of each word. The lowest pitch indicates weak stress. The result illustrated that ILE produces inappropriate word stress in second language learning. Most of them are not able to distinguish between strong and weak stressed syllables. This is because in their native language, prosodic features, such as word stress, do not prevail. Thus, English word stress production was heavily influenced by Indonesian features of stress. From the 36 words that become the instrument of this research, less than 50% were pronounced correctly, in most cases, and the highest pitch fell on last syllables. The absence of prosodic features in Indonesian language and limited knowledge on English phonetics drive the ILE to pronunciation error.�
METADISCOURSE MARKERS WRITTEN IN INTRODUCTION SECTION OF FINAL PROJECT OF UNIMUS EFL LEARNERS

Published: June 2019

Metadiscourse marker is one of determining indicators of the quality of the writers� writing. Metadiscourse markers enable the writers to interact with the readers effectively. What commonly happens to many undergraduate students studying English as a foreign language is that they are not able to develop an engagement between themselves, their texts, and their readers. Thus, this study investigates the types of metadiscourse markers used by Unimus EFL learners in final project introduction sections, and markers that are frequently used by them in their writing. By using qualitative and quantitative research method, seven introduction sections of final project of Unimus EFL learners focusing on qualitative and qualitative research methods were chosen purposively. As result, the study revealed that in writing introduction sections, the students used various metadiscourse markers, including interactive resources (transitions, frame markers, endophoric markers, evidentials, and code glosses) and interactional resources (hedges, boosters, attitude markers, engagement markers, and self-mensions). Among those categories, interactive resources were found to be frequently used by the learners rather than interactional resources. It means that the writers tended to give attention to and guided the readers through the text by establishing their interpretations explicitly rather than involving the readers in the argument through the use of markers in interactional dimension.

The research aims at describing the development of PROTADROID, an Android Table Program, to assist learners� pronunciation practice by using non-native English speakers and investigating the affective aspects of using the PROTADROID. The method used was Research and Development (R&D) which has been chosen to produce a product and test the affective aspects of the product. In order to find out the affective aspect, a questionnaire was applied as an instrument in the data collection. Thirty participants were randomly selected from two Pronunciation Practice classes at Universitas Indraprasta PGRI Jakarta. Based on the development phases, PROTADROID is valid and practical. Further, the four affective aspects indicate that satisfaction is 88.2% (very satisfied), interest is 93% (very interested), attention is 76% (positive), and involvement is 85% (positive). Hence, it can be concluded that students generally understand and are capable of operating PROTADROID application with high interest.
