Discoveries and novel insights in ecology using structural equation modeling
Authors: Laughlin Daniel , Grace James
Published: September 2019

As we enter the era of data science (Lortie 2018), quantitative analysis methodologies are proliferating rapidly, leaving ecologists with the task of choosing among many alternatives. The use of structural equation modeling (SEM) by ecologists has increased in recent years, prompting us to ask users questions about their experience with the methodology. Responses indicate an enthusiastic endorsement of SEM. Two major elements of respondent’s experiences seem to contribute to their positive response, (1) a sense that they are obtaining more accurate explanatory understanding through the use of SEM and (2) excitement generated by the discovery of novel insights into their systems. We elaborate here on the detection of indirect effects, offsetting effects, and suppressed effects, and demonstrate how discovering these effects can advance ecology.

Background: According to the World Health Organization (WHO), up to 18% of the whole population in Saudi Arabia have DM (diabetes mellitus). Thyroid disorders are the most common endocrinal diseases among Type 1 diabetic (T1D) patients. This study aims to investigate the prevalence of thyroid disorders among T1DM patients. Methodology: A retrospective study was conducted on 239 patients with T1DM and data on the levels of HgA1c, TSH, T3, and T4 were collected from patients\' files. Results: Abnormal levels of HbA1c, TSH, T3, and T4 were present in 99.6%, 11.3%, 69.5% and 12.1% of patients respectively. The mean HgA1C was 9.781 ± 2.12, and for TSH it was 3.71± 10.67 uU/mL. The mean value for free T3 level was 6.42 ± 1.320 pmol/L, and for T4 levels it was 11.30 ± 2.486 pmol/L. No statistically significant relationship was found between the levels of HgA1c, TSH, T3 or T4, and both age groups and gender of the participants. T3 levels were significantly higher among pump users compared to metered-dose inhaler (MDI) users. Conclusions: This study calls for the assessment of thyroid profile in all type 1 diabetic patients in their routine evaluation to allow early detection and management of any thyroid dysfunction among those patients.

Published: September 2019

Examinamos a atuação do jornal Folha de Caxias no processo de criação da Associação Beneficente de Menores e do Patronato São Bento, em Duque de Caxias (RJ). A Associação foi criada para instituir e dirigir o Patronato, destinado a educar crianças em situação de vulnerabilidade social. O jornal pautou o tema da “infância desvalida”, defendendo que os menores “abandonados” nas ruas contribuíam para uma visão negativa da cidade. Na perspectiva teórico-metodológica adotada, a imprensa foi tratada como fonte e objeto de investigação.

Sebagai salah satu sub-sektor industri kreatif terbesar di Indonesia, industri fesyen memiliki potensi dan kontribusi besar bagi masyarakat dan perekonomian negara. Namun, peran industri mode besar juga perlu diseimbangkan dengan metode produksi dan desain produk-produk fashion yang ramah lingkungan. Ini perlu dilakukan mengingat potensi dampak buruk dari industri fashion yang berkembang pesat tanpa arah apa pun. Efek buruknya adalah penggunaan bahan sintetis atau bahan baku yang berbahaya bagi lingkungan; limbah produksi yang belum diproses; kualitas bahan dan proses produksi yang buruk menghasilkan siklus hidup produk yang rendah; dan masalah ketenagakerjaan sosial.
Untuk mengatasi masalah di atas, metode ramah lingkungan yang saat ini digunakan oleh berbagai merek fesyen di Indonesia dan menjadi tren adalah penggunaan pewarna alami dalam proses produksi fesyen. Penggunaan pewarna alami memiliki banyak keunggulan, yaitu: menggunakan bahan yang tidak beracun dan berbahaya; melestarikan tradisi leluhur Indonesia; dan menghasilkan karakter warna yang otentik dan trendi jika diproses dengan benar.
Penelitian ini menggunakan metode kualitatif dengan pendekatan sosiokultural. Penelitian ini menyajikan latar belakang dan perkembangan penggunaan pewarna alami oleh berbagai merek fashion di Indonesia untuk menjadi tren saat ini. Dengan demikian, penggunaan pewarna alami diharapkan tidak hanya menjadi tren sesaat tetapi juga diharapkan terus dikembangkan. Alasan terbesarnya adalah bahwa penerapan metode yang lebih ramah lingkungan untuk industri fesyen Indonesia secara luas dapat memberikan banyak manfaat.
Case study: methane gas in a groundwater system located in a dolerite ring structure in the Karoo Basin; South Africa
Authors: Hohne D. , de Lange F. , Esterhuyse S. , Sherwood Lollar B.
Published: September 2019

In the past few years numerous assumptions were made on groundwater in the Karoo Basin and related shale gas development, but not many baseline studies were conducted on groundwater and on boreholes where methane currently occurs. This article focuses on one of these boreholes (BHA) in the Ubuntu Local Municipality area, located close to a dolerite ring structure, which is releasing methane gas. Water samples were analysed for macro and trace elements, environmental isotopes and methane concentrations. Chemical analyses results indicate that groundwater at this borehole may be a mixture between deep groundwater, shallow groundwater and meteoric water. A rise in the groundwater level and subsequent flowing artesian conditions that was observed, support the theory that mixing between deeper groundwater from the Ecca Group and shallower water from the Beaufort Group is taking place. These water level reactions could be due to possible seismic activity within close proximity to the dolerite ring structure and/or due to recharge and interflow to BHA.

Authors: Souza Lucas Simas de , De Souza Andreia Ferreira
Published: October 2019

Objetivo: Determinar a incidência, indicações, fatores de risco e complicações associadas com histerectomia pós-parto de emergência (HPPE)em maternidade pública de cuidados de alto risco no Estado do Amazonas.Métodos: O estudo foi do tipo descritivo, observacional, corte transversal, por meio de prontuários médicos e de livros de registros de cirurgias foram identificados os casos de histerectomias pós-parto de emergência realizadas no período de janeiro de 2016 a dezembro de 2017. Os dados foram coletados no Hospital da cidade de Manaus-Amazonas. Resultados:No período de 2016 a 2017, houve 16.978 partos no da cidade de Manaus-Amazonas, 6.873 (40,5%) corresponderam a cesarianas e 10.105 (59,5%) a partos vaginais.Ocorreram 14 casos de histerectomia pós-parto de emergência, representando uma incidência de 0,82\1.000 partos; a indicação mais comum foi atonia uterina 50%, seguida de acretismo placentário 29% e placenta prévia 21%.Conclusão: A atonia uterina foi a indicação mais comum de HPPE em nossa Maternidade e nossas taxas de histerectomia após partos cesarianos mostraram-se nove vezes maiores às que se seguiram após um parto vaginal, logo, vemos a importância da adoção de práticas obstétricas de incentivo ao parto vaginal, especialmente após o primeiro parto cesariano, o que poderia minimizar riscos para o parto atual e consequentemente diminuir nossas taxas de HPPE.
Applicability of two non-radiographic tooth size prediction methods of unerupted permanent canine and premolars, for Galle district, Sri Lanka
Authors: Perera W. Kathya , Gunawardane Sumith , Pathirage Sumith Loku
Published: September 2019

Introduction:

Mixed dentition space analysis necessitates accurate prediction of size of the unerupted permanent teeth. The methods commonly employed are the radiographs, correlation and regression equations, or a combination. Much interest was developed on the application of prediction tables and regression equations to avoid the radiation exposure. However, the predicted values and equations have been reported to be inaccurate on populations other than on which they were developed on. We intended to evaluate the applicability of the Moyer’s probability table and Tanaka Johnston equation in estimating the mesiodistal widths of mandibular and maxillary permanent canines and premolars in adolescents of the Galle District.

Material and Methods:

Data were collected from study models of 318 randomly selected school students aged 13– 16 years with fully erupted, intact dentitions and no significant malocclusion. The measurements were obtained by a digital caliper with a Vernier scale calibrated to the nearest 0.01 mm. The data were subjected to statistical analysis to compare the actual and predicted values from Moyer’s probability table and Tanaka Johnston equation.

Results:

There was a statistically significant difference when Pearson correlation two-tailed significance test was used. The actual mesiodistal width of permanent canines and premolars and predicted widths from Moyer’s probability chart at all levels for males and females showed a statistically significant difference at 0.01 level. The values from Tanaka Johnston equation also showed a statistically significant difference at P = 0.01/R = 0.47.

Conclusion:

Moyer’s prediction table and Tanaka Johnston equation must be carefully used for children in Galle District, Sri Lanka. Therefore, it might be safer to develop regression equations for our population.

Küreselleşmenin etkisi ile birlikte birçok sektörde hız kazanan rekabet, sağlık hizmetlerini de etkilemiştir. Sağlıkta yeni ve daha kapsamlı tedavi yöntemlerinin ortaya çıkması ve teknolojik gelişmeler ile birlikte maliyetler artmaktadır. Değişen koşullar ile birlikte sağlık hizmeti sunucularının finansal sürdürülebilirliklerini sağlayabilmeleri için maliyet analizleri önem kazanmıştır.
Ekonomik değerlendirme yöntemleri sınırlı kaynakların tahsisinde rasyonel kararlar sağlayan araçlardır. Yeni tedaviler, ilaçlar ve tıbbi malzemeler hakkında maliyet ve fayda karşılaştırmaları yapmakta ve politika yapıcı ve karar vericilere en etkili alternatifin seçiminde yardımcı olmaktadır. Sağlık hizmetlerine ayrılan kaynakların kısıtlı olması sebebi ile birçok karar verme sürecinde ekonomik değerlendirme yöntemlerinin kullanımının gerekli olduğu düşünülmektedir. Bu çalışmada daha önceki çalışmalarda kullanılan ekonomik değerlendirme yöntemleri incelenmiştir. Araştırma sonucunda maliyet etkililik yönteminin sıkça kullanıldığı, maliyet hesaplarında hizmet maliyetlerinin daha çok incelendiği, hastalık maliyetine yönelik çalışmaların sınırlı olduğu tespit edilmiştir. Özellikle hastalık maliyetinde hastalığın sosyal maliyetinin ele alındığı çalışmalar yetersiz kalmaktadır.

Deep Generative Model for Sparse Graphs using Text-Based Learning with Augmentation in Generative Examination Networks
Authors: van Deursen Ruud , Godin Guillaume
Published: September 2019

Graphs and networks are a key research tool for a variety of science fields, most notably chemistry, biology, engineering and social sciences. Modeling and generation of graphs with efficient sampling is a key challenge for graphs. In particular, the non-uniqueness, high dimensionality of the vertices and local dependencies of the edges may render the task challenging. We apply our recently introduced method, Generative Examination Networks (GENs) to create the first text-based generative graph models using one-line text formats as graph representation. In our GEN, a RNN-generative model for a one-line text format learns autonomously to predict the next available character. The training is stopped by an examination mechanism checking validating the percentage of valid graphs generated. We achieved moderate to high validity using dense g6 strings (random 67.8 +/- 0.6, canonical 99.1 +/- 0.2). Based on these results we have adapted the widely used SMILES representation for molecules to a new input format, which we call linear graph input (LGI). Apart from the benefits of a short compressible text-format, a major advantage include the possibility to randomize and augment the format. The generative models are evaluated for overall performance and for reconstruction of the property space. The results show that LGI strings are very well suited for machine-learning and that augmentation is essential for the performance of the model in terms of validity, uniqueness and novelty. Lastly, the format can address smaller and larger dataset of graphs and the format can be easily adapted to define another meaning of the characters used in the LGI-string and can address sparse graph problems in used in other fields of science.

Polymers comprised of redox-active organic radicals have emerged as promising materials for use in a variety of organic electronics, including fast-charging batteries. Despite these advances, relatively little attention has been focused on the diversification of the families of radicals that are commonly incorporated into polymer frameworks, with most radical polymers being comprised of nitroxide radicals. Here, we report two new examples prepared via ring-opening methathesis polymerization containing 6-oxoverdazyl and nitronyl nitroxide radicals appended to their backbones. The polymerization reaction and optoelectronic properties were explored in detail, revealing high radical content and redox activity that may be advantageous for their use as semiconducting thin films. Initial studies revealed that current-voltage curves obtained from thin films of the title polymers exhibited memory effects making them excellent candidates for use in resistive memory applications.

Published: September 2019

Recent studies show the limitations of catalytic activity descriptor-based approaches to rationalize the kinetics of the hydrogen oxidation and evolution reactions (HOR/HER). Herein, we deposited several transition metals (TMs) onto Pt surfaces to disturb and probe the interface in alkaline solutions. The redox transition of these TMs in association with adsorption and desorption of reaction intermediates during the HOR/HER was monitored via in situ X-ray absorption spectroscopy. We propose that the TM facilitates the HOR by anchoring H2O with the H-up configuration (↑H2Oad) that removes Had on Pt via the bifunctional mechanism, based on the first in situ experimental evidence for the presence of ↑H2Oad on surface Ru. Meanwhile, the TM promotes the HER of Pt by anchoring OHad to trigger the hard–soft acid–base (HSAB) mechanism for OHad removal. The revised 2B theory depicts a coherent picture of the HOR/HER kinetics in aqueous solutions.

Authors: Teator Aaron , Varner Travis , Jacky Paige , Sheyko Karolina , Leibfarth Frank
Published: September 2019

A series of isotactic, semicrystalline vinyl ether copolymers (up to 94% meso diads) were synthesized using a chiral BINOL-based phosphoric acid in combination with a titanium Lewis acid. This stereoselective cationic polymerization enabled the systematic tuning of both glass-transition (Tg) and melting temperature (Tm) in copolymers derived from alkyl vinyl ethers (i.e., ethyl, butyl, isobutyl). Additionally, a vinyl ether comonomer bearing an acyl-protected alcohol was utilized as a platform for post-functionalization. Copolymers containing the masked alcohols were shown to undergo facile deprotection and subsequent coupling with a desired acid chloride. Collectively, these results highlight the diverse material properties and expanded chemical space accessible through stereoselective cationic polymerization mediated by a chiral anion.

Authors: Pasnicu Daniela , Ghinararu Catalin
Published: September 2019

Lately, the European Union has made progress in the labor market, especially in terms of employment, except in the economic crisis. The purpose of the article is to highlight the main labor market trends at European Union level, with an emphasis on employment as well as differences between Member States in the context of current challenges, namely long-term demographic trends and technological change. In this respect, two EU Member States, namely Romania and the UK, were also taken into account in order to highlight the differences between advanced and less advanced economies in terms of employment opportunities and the integration of vulnerable people on the labor market. The analysis, which emphasizes demographic change and employment, can serve as a basis for knowledge for the design of national policy instruments by emphasizing deficits, surpluses or equilibria. Trends are analysed dynamically over the 2007-2017 period, based on EUROSTAT data. The challenge for decision-makers is to increase labor force participation and to ensure that every citizen has the chance to make full use of his productive potential.
Música para ver, teatro para ouvir: aspectos idiomáticos da música-teatro de Gilberto Mendes
Authors: Magre Fernando
Published: October 2019

Constança Capdeville é a maior representante do teatro-música em Portugal. As suas composições vão além do musical, incluindo recursos extramusicais, como adereços, luzes, imagens, elementos teatrais e gravações em fita magnética. Esses recursos foram introduzidos nas suas obras, seja para estabelecer ambientes, estados emocionais ou para definir espaços. As obras de teatro-música de Capdeville, apesar de seu sucesso, também suscitaram reações controversas no público. Na perspetiva da compositora, a ópera e o concerto tradicional tinham terminado e, portanto, o conceito do palco deveria ser repensado. Capdeville referiu que, muitas vezes, teve que resolver esse problema criando os seus próprios palcos. Neste artigo, discutiremos o conceito de teatro-música no contexto da música contemporânea portuguesa e as suas influências nas composições de Capdeville.

This article is an overview of the work that has been conducted so far on river usage and nautical technology in the history of Angkor, and a discussion on how maritime approaches can contribute to the creation of new knowledge by opening new lines of research that can help us reconstruct a more nuanced view of Angkor’s fluvial history. Although Angkor’s connection to the river network was made in the early 20th century, the compartmentalized studies that have been carried out so far on the subject of Angkor’s relationship to its watery environment have resulted in interpretations that do not reflect the complexity of the subject. It will be argued here that archaeologists who do not integrate maritime approaches in studies of cultures like Angkor, where waterways play an important role in their environment, are likely to miss important aspects of fluvial cultures. By applying concepts such as the Maritime Cultural Landscape, it will be possible to push beyond the boundaries of terrestrial approaches and discover how the environmental conditions of cultures like Angkor – with river networks as the main means of communication – resulted in the development of specific cognitive and functional traits that gave form to fluvial cultural landscapes. An example of such an approach is offered as a conclusion in an analysis of masonry bridges in Angkor’s transport network.ជាទិដ្ឋភាពរួមនៃការងារស្រាវជ្រាវដែលបានធ្វើកន្លងមក ស្តីពីការប្រើប្រាស់ទន្លេ និងបច្ចេកវិទ្យាផ្លូវទឹក ក្នុងប្រវត្តិសាស្ត្ររាជធានីអង្គរ ហើយជាការជជែកថាតើមធ្យោបាយផ្លូវសមុទ្រអាចរួមចំណែកដល់ការបង្កើតចំណេះដឹងថ្មី តាមរយៈការបើកខ្សែស្រាវជ្រាវថ្មីដែលអាចជួយយើងឱ្យច្នៃឡើងវិញនូវគំហើញលាយឡំពីប្រវត្តិសាស្ត្រផ្លូវទន្លេរបស់រាជធានីអង្គរ។ ទោះបីទំនាក់ទំនងរាជធានីអង្គរជាមួយបណ្តាញទន្លេត្រូវបានសិក្សារួចហើយកាលពីដើមសតវត្សទី២០នោះ ការសិក្សាដោយបែងចែកតាមផ្នែកដែលបានធ្វើរួចកន្លងមក លើប្រធានបទ សម្ព័ន្ធភាពរាជធានីអង្គរ ចំពោះបរិស្ថានផ្លូវទឹកបានបង្កឱ្យមានការបកស្រាយដែលមិនឆ្លុះបញ្ចាំងពីភាពសាំញ៉ាំនៃ ប្រធានបទនេះទេ។ អ្វីដែលត្រូវ ដេញដោលនៅក្នុងអត្ថបទនេះគឺបុរាណវិទូ ដែលមិនបញ្ចូលមធ្យោបាយផ្លូវសមុទ្រ ចូលក្នុងការសិក្សាវប្បធម៌ដែលដូចរាជធានីអង្គរ ដែលផ្លូវទឹកដើរតួនាទីសំខាន់ ក្នុងបរិស្ថានតំបន់នោះ ទំនងជាភ្លេចចំណុចសំខាន់នៃវប្បធម៌ផ្លូវទន្លេហើយ។ តាមរយៈការអនុវត្តទស្សនាទានដូចជាទេសភាពវប្បធម៌ផ្លូវសមុទ្រ អ្វីដែលអាចទៅរួច គឺការរុញឱ្យផុតព្រំដែនមធ្យោបាយផ្លូវគោក ហើយរកមើលថាតើលក្ខណ្ឌបរិយាកាសនៃវប្បធម៌ដូចរាជធានីអង្គរ ដែលមានប្រព័ន្ធទន្លេ ជាមធ្យោបាយប្រាស្រ័យទាក់ទងចម្បង បង្កឱ្យមានការអភិវឌ្ឍសញ្ញាណចំណេះ និងមុខងារជាក់លាក់ដែលបង្កើតជា ទេសភាពវប្បធម៌ផ្លូវទន្លេយ៉ាងណា។ ឧទាហរណ៍មួយនៃមធ្យោបាយបែបនេះ នឹងផ្តល់ជាការសន្និដ្ឋាន ក្នុងការវិភាគស្ពានកំបោរនានា នៅក្នុងបណ្តាញដឹកជញ្ជូនរបស់រាជធានីអង្គរ។
Peran Perfeksionisme Orientasi Diri dalam Memediasi Pengaruh Gaya Pengasuhan Orang Tua terhadap Efikasi Diri Keputusan Karier Siswa

This present study aimed to analyze the role of self-oriented perfectionism in mediating the effect of fathers’ and mothers’ parenting styles on Career Decision Self-Efficacy (CDSE) among students in Grade 11 Senior High School. The participants of the study comprised 179 students who were selected through convenience sampling method. This study employed three instruments, namely Career Decision Self-Efficacy Short Form, Parental Authority Questionnaire, and Multidimensional Perfectionism Scale. Data were analyzed by Hayes’s PROCESS Macro. Generally, the results show that fathers’ permissive parenting and mothers’ authoritarian parenting have an influence on the degree of CDSE among students which is mediated by self-oriented perfectionism. Moreover, the effect of fathers’ authoritative parenting predicts CDSE directly without the mediation effect of self-oriented perfectionism, whilst mothers’ authoritative parenting influences CDSE both directly and indirectly. Therefore, considering the actualization of proper parenting styles is necessary in order to build perfectionism personality which supports students’ effectiveness in career decision making.Keywords: Career decision self-efficacy, parenting styles, self-oriented perfectionism, studentsAbstrak: Penelitian ini bertujuan untuk menganalisis peran perfeksionisme orientasi diri dalam memediasi pengaruh gaya pengasuhan ayah dan ibu terhadap Efikasi Keputusan Diri Keputusan Karir (Career Decision Self-Efficacy/CDSE)  siswa kelas XI SMA. Sebanyak 178 partisipan terkumpul melalui teknik convenience sampling dalam pengisian tiga macam skala, yaitu Career Decision Self-Efficacy Short Form, Parental Authority Questionnaire, dan Multidimensional Perfectionism Scale yang sudah dilakukan adaptasi ke dalam Bahasa Indonesia. Data dianalisis dengan menggunakan PROCESS Macro dari Hayes. Secara umum, hasil uji menemukan bahwa gaya pengasuhan permisif ayah dan gaya pengasuhan otoriter ibu berpengaruh terhadap tingkat CDSE siswa melalui perfeksionisme orientasi diri. Sementara itu, pengaruh dari gaya pengasuhan otoritatif ayah terhadap tingkat CDSE siswa hanya terjadi secara langsung. Adapun pengaruh dari gaya pengasuhan otoritatif ibu terhadap tingkat CDSE siswa dapat terjadi baik secara langsung atau tidak langsung melalui mediasi perfeksionisme orientasi diri. Untuk itu, dengan penerapan gaya pengasuhan yang tepat, perkembangan pribadi perfeksionisme siswa dapat mendukung kenaikan efektivitas keputusan karier masa depan.
Perbedaan Gender pada Kesadaran Metakognitif dalam Strategi Membaca Bacaan Akademik

Published: October 2019

Metacognitive awareness of reading strategies can be defined as the knowledge or awareness about strategies to process reading materials, the ability to monitor comprehension, and the ability to employ strategies in understanding text. Previous studies show inconsistent results regarding the role of gender in the metacognitive awareness of reading. The current study aims to evaluate gender differences in the students’ knowlegde of metacognitive strategies in reading. This study involves 137 students (59 boys and 78 girls) from grade 4 to 6. The current study uses Metacognitive Awareness of Reading Strategies Inventory (MARSI) that consists of 3 subscales: global strategy, problem solving, and support strategy. Results show that female students outperform male students in their metacognitive awareness, both in general scale and in each type of strategy. In addition, the most used strategy is the problem solving strategy, while the least used is the support strategy. This finding suggests that teachers need to consider the gender difference in determining the effective methods of delivering materials in classrooms. Keywords: metacognitive awareness, reading, gender differencesAbstrak: Kesadaran metakognitif dalam membaca dapat didefinisikan sebagai pengetahuan akan strategi untuk memproses bacaan, kemampuan untuk memonitor pemahaman, dan kemampuan untuk mengatur strategi yang dibutuhkan untuk memahami bacaan.

Penelitian ini bertujuan untuk menelaah lebih dalam mengenai bagaimana perbedaan siswa laki-laki dan perempuan pada kesadaran metakogntifnya dalam membaca, khususnya pada bacaan akademik. Penelitian melibatkan 137 siswa (59 laki-laki dan 78 perempuan) kelas 4 – 6 Sekolah Dasar (SD) dengan menggunakan alat ukur Metacognitive Awareness of Reading Strategies Inventory (MARSI) yang terdiri atas 3 dimensi: strategi global, penyelesaian masalah, dan strategi pendukung. Hasil penelitian menunjukkan bahwa siswa perempuan lebih sering menggunakan strategi metakognitif dibandingkan siswa laki-laki, baik secara keseluruhan maupun pada masing-masing jenis strategi. Selanjutnya, jenis strategi yang paling banyak dipakai adalah strategi penyelesaian masalah, sedangkan strategi yang paling jarang dipakai adalah strategi pendukung bacaan. Hasil penelitian ini berimplikasi pada kebutuhan guru untuk memperhatikan perbedaan gender siswa ketika menentukan metode penyampaian tugas atau materi belajar agar pembelajaran berlangsung efektif.

Change is something that will occur in any organization. The main factor that enables the organizations to achieve success in the changes they face is its’ employees’ readiness for change. This study examined the role of psychological capital in the relationship of perceived management support and readiness for change. Data were collected from 198 employees from various departments at PT. X. The sample was selected purposively based on the same criteria, namely: permanent workers from the restructured units at the company. This study used perceived management support,  readiness for change, and psychological capital scales. Data were simultaneously tested using partial least square analysis with the help of Smart PLS 3 software. This study found positive and significant relationship of perceived management support and individual readiness for change, but psychological capital does not mediate the relationship of the perceived management support and individual readiness for change.  Keywords: Perceived management support, psychological capital, readiness for change Abstrak: Perubahan merupakan hal yang pasti akan selalu terjadi pada suatu organisasi.

Published: September 2019

Solar energy creates a new lifestyle for mankind, and takes society and human into an era of energy conservation to reduce pollution. It is radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as photovoltaic panel. In this research it is aimed to design and implement PV solar energy home system for electrification in the Kuwaiti dessert during eco-tourism in winter. Eco-tourism is a cultural and unavoidable event in Arab countries with no exception of Kuwait. Eco-tourism is done in remote dessert where urban electricity connections are not possible. As people accustomed in using electrical appliances such as television, room heater, water heater, water pump, they cannot live in the dessert without these amenities. As the weather of Kuwait is sunny and hot during days and cool at night, solar panel based off-grid power cell can be an alternative for electrification of dessert home. This research will address several critical issues which are appropriate design of PV solar system, estimation of power generation and implementation as solar home system.
In vitro culture as a source of biodiversity for soybean breeding
Authors: Rozhanskaya O. A. , Gorshkova E. M.
Published: September 2019

The paper shows the effectiveness of methods of somaclonal variability in combination with multiple individual selection for creating new soybean varieties characterized by early ripeness and increased seed productivity for sub-arid regions of Russia and Kazakhstan with cold continental climate. Soybean breeding material was created using biotechnology methods combined with multiple individual selection. Higher regeneration potential of soybean tissues of SibNIIK 315 variety compared to Omskaya-4 variety was revealed. The ability to regenerate is associated with the adaptability of SibNIIK 315 variety, which is conﬁ rmed by the wider area of its cultivation in various ecological and geographical conditions in ﬁ ve regions of Russia and Kazakhstan. Tissues of apexes and cotyledonary nodes of R21 somaclonal line differed from the original SibNIIK 315 variety by the increased activity of callus formation, regeneration and growth of shoots. Tissues of regenerated plants passed repeatedly through the regeneration cycle according to the protocol of recurrent regeneration. Due to this, high morphogenic activity of R21 tissues can be the result of autoselection in vitro. The analysis of phenotypic variations in early generations of soybean somaclones showed an asymmetric distribution of deviations by the main breeding and marker traits: duration of vegetation, plant height and seed productivity, as well as dependence of distribution on weather conditions. In a dry year most somaclonal lines had a higher seed productivity, whereas in favourable conditions of a humid summer only every third line was superior to the original variety. This indicates increased levels of ontogenetic adaptation of somaclones in extreme drought conditions.

Published: September 2019

A quantitative assessment of the current state of natural fodder areas located in the Turano-Uyuk basin (Tuva) was made. Vegetation monitoring was carried out on the basis of Terra Modis satellite data by the following indicators: normalized vegetation index, gross primary production (GPP) and evapotranspiration. The productivity of plant associations was compared, their growth rate and the degree of GPP dependence on the sum of temperatures and evapotranspiration were determined. The results of ground-based studies performed by generally accepted methods were used for veriﬁ cation. Remote indicators of gross production for the growing season ranged from 33.3 t/ha for halophytic meadows, and up to 48.8 t/ ha for wetland habitats. Depending on the species composition, gross productivity of glycophytic meadows during the growing season was 39.9– 48.7 t/ ha. A comparison of the data showed signiﬁ cant differences in the remote and actual productivity of fodder areas, which can be leveled by means of correlation with the ground-based indicators. The best results of the relationship between gross primary production and the vegetation index with the sum of positive temperatures were identiﬁ ed by polynomial equations of the third degree. The maximum period of phytomass development of natural fodder areas (meadow communities) was recorded before the beginning of June. Biological and environmental differences in the growth of vegetation during the season were noted in the period from 10-11 June to 19-20 July. The decrease in the accumulation of gross primary production by mid-July and the end of September was caused by weather conditions. The optimal grazing periods in the meadows in the Turano-Uyuk basin were determined.

The work presents the results of research into productivity of traditional and uncommon silage crops – sunﬂ ower and Sudan grass – sown as a single crop and intercropped with broad beans, spring rape and oil radish. The study was carried out on meadow chernozem mealy-carbonate soil in the forest-steppe zone of Trans-Baikal Territory. The objects of the research were the following recognized varieties: Yenisei sunﬂ ower, Sudan grass Novosibirsk 84, broad beans Sibirskiye, spring rape Spat, oil radish Tambovchanka.  Agricultural technology used for fodder crop cultivation was common for this area. Sunﬂ ower was sown both as a single crop and intercropped with broad beans in the third ten-day period of May in wide alternating rows. Sudan grass was sown both as a single crop and intercropped with spring rape and oil radish in the second ten-day period of May in rows. The experimental work was carried out alongside laboratory observations and analyses in accordance with the generally accepted guidelines for ﬁ eld experiments on fodder crops. The possibility of increasing fodder productivity and nutritional value of silage agrocenoses was established by means of intercropping sunﬂ ower and Sudan grass with broad beans and cabbage crops (spring rape and oil radish) and sowing them in herbage in alternating rows. The experiment noted the maximum collection of feed units of 2.96-5.22 t/ha, digestible protein of 414.2-621.1 kg/ha and gross energy of 35.467.1 GJ/ha with the availability of digestible protein in the amount of 118.9-139.9 g per one feed unit and 10.0-10.7 MJ of metabolic energy per 1 kg of dry matter.

Published: October 2019

Early blight (Alternaria solani) is a potential disease of potato that reduces its production globally both in conventional and tunnel cultivations. Due to variability in pathogenic isolates, prolonged active disease cycle phase and broad host range early blight is very difficult to manage. 8 microorganisms as a bioagent exhibiting inhibitory affects against Alternaria solani, were screened for their activity towards A. solani by a dual culture in vitro assay and in vivo (whole plant) test.in vitro studies indicated that the microorganism’s strains strongly inhibited the mycelial growth of the pathogen. The effect of microorganism’s strains on the mycelial growth (mm) of the pathogen proved to be highest with Trichoderma sp. (0.55) followed by Pseudomonas brassica cearum (0.74) and Pseudomonas jessenii (0.81) on the high concentration (106 cells ml-1) compared to the control (2.30). On the other hand, Bacillus mycoides (2.14) in vivo studies 9 microorganism’s strains were applied in two different application (foliar – soil) and two different varieties (Labella – Romano). The results showed significant reductions in the disease severity (%) with the treatment by Trichoderma sp (2%) followed by Bacillus thuringiensis (3%) and Bacillus mycoides (5%) compared with the control (46%) of Romano variety, while there were a less significant reductions in the disease severity (%)with the treatments compared with the control (16%) of Labella variety . The efficacy of antagonists to suppress the early blight disease varied in respect to the time and type of application.
ARIA 3.0: A Modern Approach to Web-based Music Festival Registration Systems

Published: September 2019

Administration, Registration, and Information Assistant (ARIA) 3.0 is a full-stack web- application developed to assist the Northern Nevada Music Teachers Association (NNMTA) with numerous music festivals and competitions occurring annually. ARIA’s primary func- tionalities are the following: event creation, event scheduling, event management, user management, document processing, and payment processing. Prior to the creation of ARIA, these functionalities were performed using-paper methods. This approach was tedious, inefficient, and prone to errors. The previous versions of ARIA (1.0/2.0) were developed to address these issues using the WordPress platform and WordPress plugins. While successful, new business requirements proposed by NNMTA have demonstrated that WordPress may not be a feasible software platform for all of NNMTA’s needs going for- ward. To ensure that ARIA can advance with NNMTA, ARIA 3.0 was developed using an “as-is” and “to-be” design approach. We built a microservice application which supports the implementation of features that NNMTA would like to maintain from previous versions while simultaneously providing a platform suitable for future software requirements. Additionally, new portals built for customers, students, teachers, and administrators aim to improve the user experience (UX) and user interface (UI) by increasing engagement with ARIA through new functionalities, greater access, and greater control over information.
