Determinants of the Adoption of Mobile Learning Systems among University Students in Indonesia
Authors: Pramana Edwin
Published: September 2018

Aim/Purpose: This study investigates the factors that influence university students’ intentions to adopt mobile learning for their learning activities. A theoretical model is developed based on prior research incorporating constructs from the Unified Theory of Acceptance and Use of Technology (UTAUT), the Technology Acceptance Model (TAM), and specific mobile learning constructs, as well as the moderating effects of gender and experience.

Background: Mobile Learning, the use of smartphones and other mobile devices in accessing education materials, has become increasingly popular in the last decade. Despite the widespread use of smartphones by students, not many universities have adopted mobile learning in their teaching and learning activities.

Methodology: A paper-based questionnaire was used to collect data. A final sample of 696 student responses from five urban universities in Indonesia was used. All of the constructs in the model are measured using existing scales. Structural Equation Modeling (SEM) was used to analyze and develop the theoretical model using Amos software.

Contribution: This research contributes to the theoretical understanding of mobile learning adoption as well as practice and provides guidance for university managers to successfully implement mobile learning in their universities. In particular, the study explores moderating effects due to gender and mobile learning experience and presents more complete findings based on total effects instead of only considering direct effects.

Findings: Perceived Enjoyment and Perceived Usefulness are the two most influencing factors in the adoption of mobile learning. Gender moderates the direct effect of learning autonomy on behavioral intention. New findings include significant correlations and causal effects involving learning autonomy, perceived enjoyment, facilitating condition, perceived mobility, social influence, perceived usefulness, and perceived ease of use.

Recommendations for Practitioners: University managers should ensure that the students can enjoy mobile learning and also find it useful for their learning activities. Furthermore, the University has to facilitate and support the mobile learning system and infrastructure, and they also need to create a university learning environment where professors, senior students, and friends all encourage the adoption of mobile learning.

Recommendation for Researchers: Research on mobile learning adoption should consider the moderator effects on the factors of behavioral intention to adopt mobile learning. Different groupings within these moderators should also be examined.

Future Research: Additional studies may address and compare findings with respondents from rural Indonesian universities where the infrastructure and facilities are inferior to those in urban universities as well as participants from other cultural contexts.

Published: September 2018

En este trabajo se hizo una evaluación de costos en la etapa de lixiviación en un proceso de blanqueamiento de arcillas caoliníticas, para lo cual se analizaron dos diferentes métodos de saturación de los licores de lixiviación. En Ambos métodos se requiere de agitación constante y temperatura de 90°C y se utilizan como reactivos ácido cítrico y tiosulfato de sodio diluidos en agua desionizada para remover las impurezas presentes en el caolín. En uno de los procedimientos se lixiviaron 5 kg de caolín, por períodos mayores a 240 minutos lo que implica emplear mayor cantidad de energía en el reactor y en un segundo procedimiento se recircularon los licores de lixiviación para blanquear 10 kg de arcilla caolinítica, sin necesidad de añadir mayor cantidad de reactivos. Se investigaron los costos de los reactivos, del consumo de energía eléctrica del reactor, del consumo de agua en servicios industriales y el costo del caolín extraído a pie de mina y de alta pureza. Comparando costos y analizando el precio de venta, se concluyó que el método más factible, para el blanqueamiento del caolín, es en el que se hace la recirculación de los licores de lixiviación en nuevos procesos de blanqueo.
Depression and Personality Traits
Authors: Pérez- Pacheco Yary Zulay J
Published: September 2018

Temperament is a risk factor for major depressive disorder, more specifically neuroticism or negative emotionality and it seems that higher levels makes the subjects more likely to develop depressive episodes in response to stressful life events. The objective of this review is to establish those personality traits that are most related to depression. From all the articles, seven of them are about the high levels of neuroticism and low levels of extroversion in depressive patients, this for the theory of the five factors. On the other hand, the studies based on the Cloninger theory talk about high levels of damage avoidance and low levels of self-directivity that are related to the presentation of the disorder. Regardless of the theory used, it becomes evident the need to interrogate personality traits in psychiatric and healthy patients, in the latter for the prevention of disorders.

Strategic Retention: Principal Effectiveness and Teacher Turnover in Multiple-Measure Teacher Evaluation Systems
Authors: Grissom Jason A. , Bartanen Brendan
Published: September 2018

Studies link principal effectiveness to lower average rates of teacher turnover. However, principals need not target retention efforts equally to all teachers. Instead, strong principals may seek to strategically influence the composition of their school’s teaching force by retaining high performers and not retaining lower performers. We investigate such strategic retention behaviors with longitudinal data from Tennessee. Using multiple measures of teacher and principal effectiveness, we document that indeed more effective principals see lower rates of teacher turnover, on average. Moreover, this lower turnover is concentrated among high-performing teachers. In contrast, turnover rates of the lowest-performing teachers, as measured by classroom observation scores, increase substantially under higher-rated principals. This pattern is more apparent in advantaged schools and schools with stable leadership.

Interventions analysis of addressing exclusive breastfeeding (EBF) barriers to improve EBF coverage among industrial women employees in indonesia
Authors: Astuti Andari Wuri , Morgan Rosemary
Published: September 2018

Low coverage of EBF is a global public health problem. Employment has been recognized as a factor that contributes to additional problems of EBF practice among women employees in Indonesia as they work more than 8 hours per day. In Indonesia, about 200,000 industrial companies which employed women in their production activities and they give only 3 months maternity leave. As a result, the coverage of EBF among industrial remains low. While policies already exist, the technical guidelines on the interventions are not well implemented due to unpractical approaches on these guidelines. This dissertation aims to analyse the interventions to address barriers of EBF in order to increase EBF coverage among industrial women employees in Indonesia. This is an in depth study using secondary data to review best practices to increase low coverage of EBF among industrial women employees. Propose of the study was to provide recommendations that could be implemented in Indonesian setting. The study show that there are three group level barriers i.e individual, group and social-culture contributed to low coverage of EBF. The analysis revealed that work place intervention such as lactation program and increasing employersâ€™ awareness on breastfeeding are effective in implementation and feasible to be implemented in Indonesia. Another intervention is personal intervention i.e prenatal planning and preparation, job sharing and day care. It is recommended that those two interventions could be implanted simultaneously to address the barriers of EBF practice among industrial women employees in Indonesia.

Solar energy-assisted frost prevention in horticulture applications: integrated framework and parametric CFD modeling
Authors: Atam Ercan , Hong Se-Woon
Published: September 2018

Prevention of frost in horticulture is important, but challenging, and its realization,especially using green-energy sources, will have a huge societal impact.In this paper, first we suggest an integrated solarphotovoltaics (PV)-assisted framework where solar energy will be used as a secondary application for frostprevention (the primary application is electricity production for grid). Optimal design and operation ofthe suggested integrated system require detailed thermal modeling of air dynamics in the orchard,integrated system optimization and control tasks. Second, in this paperwe address the first task above: development of a novel, sophisticated parametric computational fluid dynamics (CFD)model for orchard air thermal dynamics for different orchard parameters (such as fruit type, climate, the number of trees,their sizes, distance between them, etc.) and boundary/initial conditions.Finally, the use of developed parametric CFD model is demonstrated through a case study to calculate the minimal thermalenergy required to prevent frost under different frost levels in a test apricot orchard located in Malatya, Turkey, which isthe world capital for dry apricot production.

Authors: Uhlmann Eckart , Reinkober Sascha , Hollerbach Tobias
Published: September 2018

Kurzfassung

Aufgrund des seriellen kinematischen Aufbaus und den serienmäßig antriebsseitig verbauten Winkelmesssystemen ist die Form- und Lagegenauigkeit von Industrierobotern bei Fräsaufgaben limitiert. Diese wird maßgeblich von den auftretenden Prozesskräften F in Kombination mit den geringen nicht-linearen Steifigkeiten c der Getriebe serieller Kinematiken beeinflusst. Ein vielversprechender Ansatz die Genauigkeit kostengünstig zu erhöhen, ist die Verwendung von abtriebsseitigen Winkelmesssystemen. Für statische Prozesse ist die Nutzbarkeit bereits validiert. In diesem Beitrag wird erstmalig die Anwendbarkeit solcher Systeme bei Bahnprozessen untersucht und anhand von Bearbeitungsversuchen in Stahl validiert.

Kurzfassung

Seit einigen Jahren steigt die Anzahl von Roboteranwendungen, bei denen Roboter ohne Schutzzaun, d. h. in einer Mensch-Roboter-Kollaboration (MRK), betrieben werden. Die Wirtschaftlichkeit dieser Anwendungsfälle ist vor allem in der Montage häufig nicht gegeben. Daher gibt es ein großes Interesse, sinnvolle Applikationen in bestehenden Montagesystemen zu finden. Hierzu gibt es eine Reihe von Instrumenten, welche das Automatisierungspotenzial bestehender Prozesse bewerten, die jedoch sehr aufwändig sind. Daher hat das Fraunhofer- IAO eine Vorgehensweise und Toolunterstützung zur aufwandsarmen Identifikation von sinnvollen MRK-Applikationen entwickelt.

Published: September 2018

Metallographic methods which are typically comprising chemical etching processes are applied to reveal grain boundaries in sections of metallic materials. In the case of an optically anisotropic material, grain boundaries can also be detected suing polarized light microscopy (PLM). To this end, the identification of grain boundaries, an automated image processing procedure, based on PLM, was developed. In this context, two different α Ti-based alloys were examined: a cast, non-porous rod material and a material obtained by powder metallurgy which, owing to its high porosity, places specific demands on the image processing system. The present work outlines the underlying metallographic and computer-based methods.

Authors: Sorokin I. B. , Gaag A. V. , Chudinova Iu. V. , Sirotina E. A.
Published: September 2018

The paper reveals the experimental results of long-term agroecological monitoring of agricultural land, conducted by Tomsk state agrochemical service, and experiments on designing the measures to improve efficiency of acidic arable land. In Tomsk region, 83% of arable land is acidic and the degree of acidity increases annually. Every 10 years weighted average pH is reduced on 0.1-0.2 units; the area of acidic soils increases. There is an urgent need for liming these soils in order to improve efficiency of agricultural production in Tomsk region. According to the calculations, the region requires 3,248 million tons of chalky flour. The region has its own large deposits of limestone, for example Kamenskoe (61 million tons), located 50 km from Tomsk, where it is possible to produce valuable meliorant, increasing efficiency of agricultural production. The authors make case, that for successful development of agricultural production in Tomsk region, it is necessary to design and implement long-term target program “Chalking of acid soils in Tomsk region”, which assumes compensation for agricultural producers for the part of the cost of liming; design and technical support of works; local production of limestone meliorants. Implementation of the acidic soil liming program will increase annual crop production in Tomsk region on 54.9 - 129.2 thousand tons of grain units, therefore it will increase annual income on 494.1 - 1162.8 million rubles (in 2017 prices), as well as ensure further increase in agricultural land fertility with high fertilizer efficiency, product quality and profitability.

The paper explores  juvenile resistance of synthetic lines during inoculation of seedlings by 4 isolates of Puccinia triticina pathogens isolated from brown rust populations collected on wheat crops in Leningrad, Tambov, Chelyabinsk regions and the Krasnodar Territory. The authors shift the synthetic lines, which are recommended as initial material for selection on race non-specific resistance to leaf and stem rust: No. 5 Langdon / Ku-2096, No. 9 Ukr-Od 952.92 / Ae. sq.(1031), №14 Langdon / Ku -2075, №19 Ukr-Od 1530.94 / Ae. sq.(1027), No. 21 Langdon / Ku20-9, No. 22 Langdon / Ig 48042, No. 24 Aisberg / Ae. sq.(511), No. 29 Langdon / IG 126387, No. 42 UKR-Od 1530.94 / Ae. sq.(310) and No. 52 Langdon / Ku-2100. The authors identify gene resistance to brown rust and conducted genotyping of the synthetic lines by SNP-markers associated with resistant gene to stem rust Sr2. The researchers outline synthetic lines №19 UKR-Od 1530.94 / Ae. sq.(1027) which carries a combination of resistant genes  Lr34 + Lr39 (Lr41), characterized by high resistance in the later stage of development in Omsk and Leningrad regions; and №24 Aisberg / Ae. sq.(511) with age resistant  gene to stem rust Sr2, characterized by moderate resistance to stem rust populations in the conditions of Western Siberia.

ЗОВНІШНЯ ПОЛІТИКА КРІЗЬ ПРИЗМУ ГРОМАДСЬКОЇ ДУМКИ
Authors: Міщенко Алла Борисівна
Published: September 2018

У статті досліджуються багатоаспектні особливості впливу громадської думки на формування й реалізацію зовнішньополітичної діяльності країни. Використовувався міждисциплінарний підхід, який поєднав напрацювання з соціології, права, політології та міжнародних відносин. На основі історичного методу вдалося екстраполювати отримані практики ХХ ст. щодо врахування суспільної думки на сучасні міжнародні події, системний метод визначив державу як суб’єкта міжнародних відносин, враховуючи окрему роль її інститутів, порівняльний метод дозволив вирізнити особливості впливу громадян на державні рішення у різних політичних режимах, а біхевіористський – дозволив виокремити умови зміни поведінки громадян, суспільства щодо зовнішньої політики. Здійснений аналіз наукових підходів реалізму та лібералізму визначив історичні епохи їх формування та основні тенденції врахування або ігнорування настроїв громадян на рівні державної політики щодо короткострокових та стратегічних завдань влади в реалізації її зовнішньої політики. Було визначено групи країн, де вони  найбільш відображаються. Важливим висновком дослідження, відповідно, стало окреслення маніпулятивної складової формування громадської думки за допомогою ЗМІ, особливо демократичними країнами, щодо найбільш важливих подій типу вторгнення в іншу країну, коаліційна участь у міжнародних конфліктах, інтервенція, членство в міжурядових організаціях тощо. Відповідно, було доведено, що громадська думка є важливим процесом легітимації зовнішньополітичної діяльності держави як всередині держави, так і у взаємодії з міжнародними акторами.
ОСОБЛИВОСТІ ПРИМИРЕННЯ І МИРОБУДІВНИЦТВА В УМОВАХ ЗАМОРОЖЕНИХ КОНФЛІКТІВ НА ПОСТРАДЯНСЬКОМУ ПРОСТОРІ
Authors: Семчинський Костянтин Валерійович
Published: September 2018

В умовах російської агресії проти України особливості миробудівництва та перспективи постконфліктного примирення на пострадянському просторі постають сьогодні актуальними питаннями. Метою дослідження є виявити особливості миробудівничих ініціатив у зонах нині заморожених конфліктів на пострадянському просторі, визначити напрями і механізм успішного миробудівництва і запропонувати ефективні кроки й елементи стратегії постконфліктного примирення. Застосувавши системні, аналітичні і компаративні методи, автор обґрунтовує необхідність формування комплексної стратегії постконфліктного примирення у кожній із зон конфліктної взаємодії на пострадянському просторі. У результаті дослідження автор визначає мирне врегулювання та відновлення справедливості магістральними напрямами успішного миробудівництва у зонах тліючих конфліктів на пострадянському просторі, механізм якого має включати елементи стратегії пост-конфліктного примирення у зонах нині заморожених конфліктів. Виявлено, що миробудівничі ініціативи формуватимуть світоглядно-ціннісну та нормативно-адміністративну платформу для ефективного і успішного пост-конфліктного примирення. У висновках наводяться такі ефективні кроки для успішного миробудівництва, а у перспективі – пост-конфліктного примирення: досягнення мирних домовленостей між ворогуючими сторонами; комплекс заходів щодо роззброєння та повернення до мирного життя учасників незаконних збройних формувань; формування адекватних виборчої і партійної систем; зміцнення демократії в цілому та засоби проти рецидиву конфлікту у майбутньому. Водночас, автор робить висновок про те, що постконфліктне примирення в умовах замороженого конфлікту в повній мірі не є здійсненним, оскільки деякі з базових заходів, необхідних для ефективного постконфліктного будівництва і примирення, реалізувати технічно складно або взагалі неможливо. Авторською знахідкою є окреслення концепту «меморіалізації» пам’яті про конфлікт як надійного запобіжника проти рецидиву конфлікту у майбутньому.
УКРАЇНСЬКІ ЕТНІЧНІ КОРДОНИ. ГЕОПОЛІТИЧНЕ ВІДДЗЕРКАЛЕННЯ
Authors: Міковаєць Ярослав
Published: September 2018

Нащадки Київської Русі, російський та український етноси були учасниками експансії російської імперії у тихоокеанському напрямі. Особлива роль у цьому випала козакам. Із погляду на сильний політичний центр і централізований державний апарат російський етнос став домінуючим стосовно українського. У радянські часи українці були піддані русифікації. Сучасні кордони України не включають у себе етнічно українські землі, розташовані на території Російської Федерації, котрі з 30-х рр. ХХ ст. поступово були русифіковані. До них відносяться Кубань, південна частина Воронежчини і Білгородщини, Стародубщина та околиці Таганрога. У просторовому суперництві України і Росії можна побачити багато моделей, що можуть бути пояснені тільки на основі геополітики.
