Results and Implications Following a Twelve-Year Monitoring of Ash (Fraxinus spp.) Mortality Due to Agrilus planipennis in an Urban Forest Plantation
Authors: Kumaran Subburayalu Sakthi , Sydnor Davis
Published: May 2021

Identifying ash genotypes that are resistant to emerald ash borer (Agrilus planipennis Fairmaire) (EAB) continues to be an effort of importance to widen the existing knowledge on interspecific variation in EAB-host preference, identify mechanisms involved in EAB infestation, and aid in development of EAB-resistant ash hybrids that could potentially serve as viable replacements in urban plantations. A research plantation composed of 17 cultivars and 2 seedlings of ash trees was established in Toledo, Ohio, U.S., to monitor the susceptibility of these trees to EAB. The tree mortality was recorded on an annual basis since 2005. The results from the study and its implications, at the end of 12 years of monitoring, are presented in this paper. The study reaffirmed what is known about the resistance of the Asian ash species Fraxinus mandshurica (‘Mancana’) and the general susceptibility of North American ashes to EAB. However, it was observed that the degree of susceptibility to EAB varied across the different cultivars, with white ash cultivars ‘Autumn Purple’ and ‘Rosehill’ showing higher survival rates. However, this conclusion is based on a low replication, and all but one individual of each cultivar were infested at the end of the study. The findings suggest a need for continued and thorough screening of ash cultivars for identifying resistant genotypes.

Published: May 2021

Tree-planting municipalities and organizations face multiple challenges to achieving thriving urban forests, among which is providing establishment-period care to young trees. In arid and semi-arid regions in particular, delivering water to trees is a resource- and time-intensive activity often not covered by funding specified for tree planting. This study sought to address the need for establishment-period care by producing a replicable approach to engaging residents in environmental justice communities to actively care for young street trees planted in front of their homes. Using community-based social marketing in the community of Huntington Park (Los Angeles County, California, U.S.), researchers investigated socioeconomic and cultural characteristics to barriers and motivators regarding tree stewardship (i.e., watering, mulching, and weeding) and developed an outreach program strategy accordingly. The program was pilot-tested and evaluated for effectiveness in changing behaviors. Active, in-person outreach (door-to-door engagement with residents using program materials and demonstrating tree care actions) was tested against passive outreach (program materials were left at the doorstep); both were compared to baseline conditions. Evaluation of soil moisture, tree health, and presence of mulch was conducted over a six-week period after program outreach. Trees at homes in the active outreach group had significantly higher soil moisture, more mulch, and better observed health than trees at homes in the passive outreach group. Both groups had better outcomes as compared to pre-outreach baseline conditions. Results indicate that tree planting programs with limited resources for maintenance may find success in fostering tree stewardship among residents through active engagement.

Authors: Ortega Guillermo
Published: May 2021

El surgimiento de archivos digitales relacionados con periodos de represión y violación de derechos humanos ha ampliado las prácticas de investigación sobre el pasado reciente. En 2018, la organización Artículo 19, la Comisión de la Verdad de Guerrero y El Colegio de México dieron a conocer el sitio web Archivos de la Represión, plataforma de resguardo y acceso a una parte del acervo documental legado, principalmente, por la Dirección Federal de Seguridad y la Dirección General de Investigaciones Políticas y Sociales durante la denominada Guerra Sucia en México. Este trabajo emplea la propuesta teórica de las culturas del recuerdo de Astrid Erll (2011), en especial la dimensión material, para analizar y observar al archivo digital como un medio de memoria que trastoca las narrativas sobre el pasado represivo a través de la implementación de tecnologías mediales.
AN EXPRESSION OF MATHEMATICAL CONNECTIONS IN MULTIPLICATION-RELATED THINKING IN THIRD AND FOURTH GRADES OF PRIMARY SCHOOL
Authors: Grabauskienė Vaiva , Mockaitytė-Rastenienė Oksana
Published: May 2021

Mathematical comprehension is closely related to a cognition of mathematical connections. A multiplication is a mathematical operation characterized by complex mathematical connections. Students are early introduced with the multiplication. Therefore, in primary school, not so developed cognition of mathematical connections may become a reason for difficulties in Maths. A functionality of concept is based on a view to a multiplication. The analysis scientific literature revealed that a thinking of multiplication can be either additive or multiplicative. Additionally, the multiplication learning has a variety of additive and multiplicative explanations. Because they use different specificity of visualization, the models are not equally suitable for teaching children about different properties of multiplication. Based on research, in Math classes, students are only introduced with few of the models, not covering a whole variety of them. In the research, a paper and pencil type of survey consisted of 157 participants from 3rd and 4th Grades, eight different classes from four different schools. The students had to fill the table explaining multiplication of 5 x 12 in a form of writing and drawing. The quantitative analysis of results has showed that in Grades 3 to 4, the additive view to multiplication is much more prevalent, in comparison to the multiplicative reasoning. The array model is used often but not in an extensive way. The students do not know other types of multiplicative type models. In conclusion, the results showed that students of Grades 3rd and 4th knew not enough about the mathematical connections. Therefore, teachers should pay more attention to teaching students various ways of visualizing, for children, to obtain a comprehensive understanding of the multiplication process. Acknowledgement.

Published: May 2021

This research intends to explore the training strategies used by competence-based curriculum trainers during the training of future primary school teachers, teacher training college (TTC) tutors, and TTC demonstration schools’ teachers that took place from December 2018 to January 2019 in Rwanda. The researchers visited two training sites and observed different trainers’ practices for two weeks. The analysis of results found out that the trainers have different training strategies and practices. Some of them such as role-playing, learning at the circle, interactive trainers were observed to be good training strategies as when trainers used them, trainees were motivated and provided good feedback. On the other hand, some of the training strategies such as lecture, group work and one to one trainer have shown a little interest in trainees. Therefore, this research recommends the training organisers to think of encouraging trainers to use effective training strategies as the present study revealed.

THE POLISH EDUCATION SYSTEM TODAY: AN INTERVIEW WITH KATARZYNA POTYRALA
Authors: Lamanauskas Vincentas
Published: May 2021

It is without doubt that education and teaching is a key to a better life quality of society. Many countries accentuate education quality, keeping the latter a priority of all education system. The Polish education system has faced various changes over the last few years. The Polish educa-tion system is close to the Lithuanian system, it distinguishes itself in deep traditions. It is always interesting what challenges are encountered abroad, how the education process is organized, what teaching and learning environment looks like, what challenges the 21st century education meets. One can notice that school, municipality and community collaboration is extremely vivid in Polish schools, a very great attention is devoted to history and geography, patriotism and citi-zenship education. This is also very important for Lithuanian education. Both Lithuanian and Polish education become not resistant to the influence of globalization. As Duoblienė notices (2011), globalization leaves less and less space for separate states to solve problems, especially in education sphere. For example, regardless that Poland is a much bigger state than Lithuania con-cerning both territory and population, similar problems are characteristic of both countries. For example, in Poland the same as in Lithuania are observed poor demographic tendencies, emigra-tion and other. The previous time (Lamanauskas, 2017) we were talking with professor Anna Klim-Klimaszewska from the Siedlce University of Natural Sciences and Humanities. This time we are talking with Kracow pedagogical university professor Katarzyna Potyrala.
Developing Parking Accumulation Levels to Formulate Land-Use Based On-Street Parking Policies in a Indian city - A case study
Authors: Dave Sanjaykumar
Published: May 2021

Demand for on-street parking is function of land use and therefore, it becomes imperative to investigate the effect of land-use type on on-street parking characteristics for developing land-use based on-street parking policies. To comprehend the aim, two diverse representative land-use types namely commercial and hospital were selected in the central business district (CBD) area of Rajkot city, India. Microscopic investigation was carried out by collecting demand data at every 10min monitoring interval during peak parking hours using license plate method. Investigation revealed that, land-use type significantly affected on-street parking characteristics and therefore, it becomes necessary to develop land-use based on-street parking policies. Parking index was identified as potential measure to formulate land-use based on-street parking policies, which was outlined into different levels representing parking accumulation levels (PAL). In context to the developed accumulation levels based on land-use type, the study proposes to formulate on-street parking policies based on turnover, if parking index delineates in PAL A and PAL B respectively. However, if parking index encompasses other than PAL A and PAL B, then only accumulation of parking demand should be considered for formulation of paid parking policies. The developed PAL provides a common platform for viewing on-street parking as a land-use based phenomenon.
Fuel consumption optimisation using structural equation modelling and genetic algorithm approach: The case of commercial aviation
Authors: Singh Vedant
Published: May 2021

The main aim of this study is to develop a model for minimising fuel consumption in civil aviation. Structural equation modelling (SEM) is utilised for this purpose and the model is developed in terms of various factors that influence fuel consumption in civil aviation. Total 249 questionnaires were sent out to aviation experts to identify the decision variables of strongly correlated dimensions. The results of SEM show four key underlying factors that have a positive effect on both fuel consumption and fuel optimisation. These factors are aircraft design and technology, aviation infrastructure and operation management, socioeconomic measures and the use of alternative fuels. Fuel consumption of commercial transport aircraft was reduced using a genetic algorithm. The results of this study reinforce that fuel consumption optimisation could have a distinctive effect on competitive benefit and structural performance commercial aviation.
A new proposal for fare differentiation for the Integrated Time Ticket in the city of Rome
Authors: Marabucci Alessio
Published: May 2021

The purpose of this work is to assess the possibility for the Rome city council and ATAC, the company which manages Local Public Transport (LPT) in the capital, to introduce a fare differentiation for the Integrated Time-Ticket (ITT), meaning by this the definition of two distinct fares for the ticket in question, one referring to the peak time and the other to the soft off peak time. These fare schemes are very widespread in other European countries, but also in Italy this approach to the redesign of fare offers is gaining ground; in fact, even in Milan there are already monthly and annual subscriptions (facilitated for over 65s) that are valid only in specific "off peak" time slots). The theoretical concept underlying the fare discrimination is rooted in the microeconomic theory relating to the possibility for the monopolist, who knows the function of demand of the market (or markets) of his interest, to be able to offer goods and services at different prices, depending on the band of users concerned, depending on the different elasticity of demand at the price. In this study, the possible effects of the abovementioned price differentiation are quantified economically by estimating appropriate demand elasticities; in this way, it can be demonstrated, under specific assumptions, that differentiating the price of ATAC tickets can increase revenues from ticket sales and, at the same time, sell more tickets.

Problem Sensitivitas Touch Screen Sebagai Antar Muka End-user dan Perangkat Elektronik
Authors: Muis Saludin , Setiyadi Didik
Published: May 2021

Abstrak : Touch screen adalah perangkat yang menggantikan fungsi papan ketik dan mouse sebagai alat antar muka antara end user dengan perangkat elektronik, dimana berkomunikasi antara end user dan  perangkat eletronika dilakukan. Karena itu faktor sensitivitas pendeteksian sentuhan jari atau obyek luar menjadi hal penting pada perangkat touch screen untuk pemakaian khusus. Hal ini berhubungan dengan kecepatan respon touch screen yang menentukan laju data yang diterima perangkat elektronika. Kurang sensitif jalur-jalur tertentu pada touch screen dikenal dengan istilah phase delay, yang efeknya adalah waktu respon touch screen menjadi lebih panjang, bahkan dalam kondisi parah, dapat terjadi kesalahan data. Penelitian ini mengambil kasus produk Apple yaitu Iphone  dimana phase delay  disebabkan oleh pergeseran nilai resistansi pada jalur bahan ITO yang terkorelasi dengan kontaminasi selama proses sputter lapisan nanometer ITO.

 

Kata kunci : touch screen, sensitivitas, phase delay, resistansi, ITO.

 

Abstract : Touch screen is a device that replaces keyboard and mouse functions as an interface tool between end users and electronic devices, where communication between end users and electronic devices is carried out. Because of that, the sensitivity factor of detecting the touch of a finger or an external object is important for touch screen devices for special use. This is related to the touch screen response speed which determines the rate of data received by electronic devices. Less sensitive certain paths on the touch screen are known as phase delays, the effect of which is that the touch screen response time is longer, even in severe conditions, data errors can occur. This research takes the case of Apple product, namely Iphone, where the phase delay is caused by a shift in the resistance value in the ITO material path which is correlated with contamination during the ITO nanometer sputter layer process.

The experimental results show that nickel ferrite (NiFe2O4) nanoparticles with the size of about 9-20 nm are dispersed evenly on the GO surface denatured by nitrogen. The saturation magnetization of composite NiFe2O4/GO-N is 39,32 emu/g. Photocatalytic activities of the NiFe2O4/N-doped GO composites have been evaluated through the photodegradation of the methyl blue (MB) under the irradiation of a tungsten filament lamp 75 W - 220 V, using a UV filter. MB photodegradation efficiency reaches 98% after 240 minutes of illumination. The NiFe2O4/N-doped GO photocatalysts are recovered under the utilization of an external magnetic field and can be reused. After 3 times of reuse, MB photodegradation efficiency reaches over 87%.

Introducción: La necesidad de indicadores de calidad es notoriamente reconocida por usuarios y proponentes en el tema de evaluación de políticas públicas. Los indicadores incluyen, de manera recurrente, atributos cualitativos para los cuales hay pocos estudios que evalúen el nivel de cumplimiento. Objetivo: Aplicar un enfoque multigranular, basado en el modelo lingüístico difuso 2-tupla, a la evaluación de 13 indicadores del Programa Nacional Forestal, establecidos en el sistema de indicadores de la política social derivados del Plan Nacional de Desarrollo 2012-2018 de México. Materiales y métodos: El método utiliza el modelo de representación lingüístico difuso 2-tupla y una extensión llamada jerarquías lingüísticas extendidas, diseñada para resolver problemas con información lingüística multigranular. El nivel de cumplimiento de los indicadores se evaluó con base en cuatro criterios: claridad, relevancia, monitoreo y adecuación. Resultados y discusión: La estructura que se define en el proceso de evaluación de indicadores de política social corresponde de manera apropiada a la utilizada con el modelo lingüístico difuso 2-tupla. La evaluación resultó en una lista ordenada en la que el indicador “Tasa de variación de la producción forestal maderable” obtuvo la mejor calificación con un nivel de cumplimiento “muy alto”; otros 10 indicadores tuvieron el nivel de cumplimiento “alto” y los dos indicadores restantes se calificaron con un cumplimiento “medio”. Conclusiones: El modelo lingüístico difuso 2-tupla permitió la evaluación apropiada del nivel de cumplimiento de los atributos deseables en los indicadores.

Introducción: Ante el cambio climático, las plantas pueden adaptarse, emigrar o morir; sin embargo, la migración por dispersión natural puede ser muy lenta. Objetivo: Determinar el potencial productivo, la distancia de dispersión y el banco de semillas de Lupinus montanus Kunth (lupino) en el límite superior (4 200 m) de su distribución natural en el Nevado de Toluca. Materiales y métodos: El banco de semillas se estimó en una superficie de 1.88 m2. Se establecieron tres sitios de muestreo con plantas en estado reproductivo (15 plantas) aisladas de otras plantas adultas. La producción de semillas se determinó en trampas colocadas en las cuatro orientaciones de cada planta y se determinó el patrón espacial de dispersión. Resultados y discusión: La densidad fue 4.26 semillas∙m2 de terreno. Lupinus montanus produjo más de 5 500 semillas por planta en un ciclo reproductivo; su potencial se asoció con la altura y número de tallos. El número de semillas capturadas varió significativamente (P < 0.0001) con respecto a la distancia de la planta madre. La curva de dispersión se ajustó (P < 0.01) a un modelo exponencial negativo (R2 = 0.849). La dispersión en las cuatro orientaciones fue simétrica; 97 % de las semillas cae a una distancia ≤2 m de la planta madre. Conclusiones: Solo 3.2 % de las semillas de L. montanus alcanzaron una distancia mayor de 2 m de la planta madre; no obstante, la dispersión es uniforme en todas las orientaciones, por lo que la pendiente no representa un factor limitante para el movimiento altitudinal de la especie.

Introducción: El modelado del nicho ecológico constituye una herramienta fundamental para conocer las áreas aptas para el establecimiento de sistemas silvopastoriles, con base en los requerimientos ambientales de las especies.Objetivos: Modelar el nicho ecológico de las especies forrajeras Chloris gayana Kunth y Eragrostis curvula (Schrad.) Nees, y las coníferas Pinus devoniana Lindley, Pinus lawsonii Roezl ex Gordon y Pinus montezumae Lambert e identificar las áreas potenciales para establecer sistemas silvopastoriles.Materiales y métodos: El nicho ecológico se modeló con base en datos de sitios de colecta georreferenciados en México y 23 variables ambientales. Posteriormente se identificaron las áreas y se estimó la superficie donde confluyen las especies forrajeras con las coníferas tanto en zonas agrícolas como en forestales.Resultados y discusión: Las áreas potenciales para establecer sistemas silvopastoriles con las cinco especies se encontraron principalmente en el Eje Neovolcánico y la Sierra Madre del Sur, con mayor superficie apta en zonas agrícolas que forestales. la especie P. devoniana tuvo la mayor superficie potencial para ser intercalada con C. gayana y E. curvula. Los modelos de nicho ecológico tuvieron alta capacidad predictiva con valores de área bajo la curva mayores de 0.93. La altitud y el rango anual de la temperatura fueron las variables de mayor importancia.Conclusiones: En México existe potencial para establecer sistemas silvopastoriles con las especies bajo estudio en el centro y sur del país, lo cual podría contribuir a disminuir la degradación del suelo, proveer forraje para el ganado y mantener la cobertura arbórea en zonas agrícolas y forestales.

AbstractThis article aims to explain and reflect an ecological understanding of the natural environment from a theological perspective of frugality. The existence of the thought that humans as the center that result in exploitative actions against nature, treat nature, the environment as objects make environmental damage everywhere. The paradigm of humans who are masters also destroys the relationship between humans and nature itself. Therefore, human consciousness, which began to appear to be struggling with this, presented an ecotheological reflection of the spiritual dimension of spirituality. That way, harmony, loving nature can be formed, applied to human thinking. This study uses a qualitative method with a literature approach to describe the ecotheological views of beauty from various kinds of literature. The results of this study concluded that there were various kinds of views ranging from spirituality, philosophy, and reflection. All of them aim at bringing justice, love, and a sufficient life to be able to build a human attitude for nature and the environment. The eco-theology of passion is also presented by the church in the form of preaching the Word, education, and pastoral care so that the congregation is given a good understanding of the importance of caring for nature which is also God's beautiful creation.AbstrakArtikel ini bertujuan untuk menjelaskan serta merefleksikan suatu pemahaman ekoteologi mengenai lingkungan serta alam dari perspektif keugaharian. Adanya pemikiran bahwa manusia sebagai pusat yang mengakibatkan tindakan eksploitatif terhadap alam, memperlakukan alam, lingkungan sebagai objek membuat kerusakan lingkungan dimana-mana. Paradigma manusia yang adalah tuan juga merusak tatanan relasi manusia dengan alam itu sendiri. Oleh karena itu, kesadaran manusia yang mulai nampak menggumuli hal tersebut menghadirkan suatu refleksi ekoteologis dari dimensi spirtualitas keugaharian. Dengan begitu, keselarasan mengasihi alam dapat dibentuk serta diterapkan dalam pola berpikir manusia. Penelitian ini menggunakan metode kualitatif dengan pendekatan kepustakaan untuk mendeskripsikan pandangan-pandangan ekoteologis keugaharian dari berbagai macam literatur. Hasil dari penelitian ini menyimpulkan bahwa ada berbagai macam pandangan mulai dari spiritualitas, filosofis, serta reflektif. Semuanya mengarahkan pada menghadirkan keadilan, cinta kasih, serta kecukupan hidup agar dapat membangun suatu sikap kemanusiaan bagi alam, lingkungan. Ekoteologis keugaharian juga dihadirkan oleh gereja dalam bentuk pemberitaan Firman, Pendidikan, dan pelayanan pastoral agar jemaat diberikan pemahaman yang baik mengenai pentingnya merawat alam yang juga adalah ciptaan Tuhan yang indah.
Peran Integrasi Teologi Psikologi Terhadap Pemulihan Prilaku Menyimpang
Authors: Santoso Joko
Published: May 2021

AbstractHumans were created in the image of God. Have a perfect personality. However, human perfection does not guarantee that humans are free from deviant behavior. This is evidenced by the biblical figures, namely Adam and Eve, deviating from God's law. Using literature studies in a qualitative descriptive approach. Thus, it can prove that theology is the foundation for everything related to humans and psychology which contributes according to their needs. Although the theological and psychological aspects have different roles and roles in handling patients, the integration of these two aspects certainly has a big impact on achieving expectations in behavioral problem. AbstrakManusia diciptakan segambar dengan Allah. Memiliki kepribadian yang sempurna. Namun kesempurnaan yang dimiliki manusia tidak menjamin manusia bebas dari perilaku menyimpang. Hal ini dibuktikan melalui tokoh Alkitab yaitu Adam dan Hawa menyimpang terhadap hukum Allah. Menggunakan studi literatur dalam pendekatan deskriptif kualitatif. Dengan demikian dapat disimpulkan bahwa teologi sebagai dasar fondasi atas segala sesuatu yang berhubungan dengan manusia dan psikologi memberikan kontribusi sesuai dengan kebutuhannya. Walaupun aspek teologis dan aspek psikologi memiliki peran yang berbeda satu dengan yang lain dan penanganan terhadap pasien, namun dengan terintregrasinya kedua aspek tersebut tentunya sangat memberikan dampak besar untuk meraih harapan dalam menyelesaikan persoalan penyimpangan perilaku.
Soteoria untuk Missio Dei Anugrah Keselamatan untuk Misi Allah
Authors: Sihombing Aeron Frior
Published: May 2021

Banyak orang Kristen memiliki konsep maupun tindakan yang salah mengenai keselamatan atau soteria. Soteria yang mereka miliki dan  cari hanyalah bersifat antroposentris, yang mementingkan diri sendiri atau berpusat kepada dirinya sendiri. Kecenderungannya adalah egois, yang mementingkan diri, pragmatis dan untuk kemuliaannya sendiri. Allah hanyalah sebagai pelengkap atau objek di dalam kehidupannya, yang mana Ia mencukupi dan memenuhi segala yang diingikannya melalui soteria  atau keselamatan yang telah diberikan-Nya. Soteria antroposentris ini bertentangan atau kontradiksi dengan soteria yang Allah inginkan, yaitu soteria untuk melakukan dan melaksanakan missio Dei atau misi Allah, semuanya adalah kemuliaan Allah atau soli deo glori. Dengan demikian, tulisan ini ingin merespons soteria antroposentris melalui kekristenan Injili menurut perspektif Reformed[1] untuk memurnikan ajaran yang terdapat di dalam Gereja.

Saat ini banyak orang Kristen dibingungkan dengan berbagai isu  dan peran politik yang harus dilakoninya di sekitar Pemilu—baik Pileg maupun Pilpres. Apakah orang Kristen harus hanya menyerahkan “nasib” kepada orang lain, atau harus berperan aktif dalam peran-peran dimaksud? Banyak contoh baik dari Alkitab, pribadi Yesus sendiri maupun para tokoh Kristen dan teolog yang bersinggungan baik secara langsung  maupun tidak langsung dengan soal-soal politik dan kepemerintahan. Lalu orang Kristen harus berda di mana?
Hakikat dan Tujuan Sekolah Kristen

Published: May 2021

Sekolah Kristen adalah bagian dari pendidikan Kristen sebagai mitra dari keluarga dan gereja untuk memenuhi panggilan Allah bagi setiap orang percaya.Pada dasarnya landasan dari sekolah Kristen adalah iman Kristen yang dinyatakan dalam Alkitab.Dengan demikian, sekolah Kristen mengupayakan pendidikan secara bersengaja dan terencana dengan baik, sehingga peserta didik mengalami perubahan dalam hal pengetahuan, sikap, nilai-nilai, keterampilan dan hidup bermasyarakat dengan hidup sesuai kehendak Allah. Tujuan utama sekolah Kristen adalah  membawa peserta didik mengenal Allah di dalam Pribadi Yesus Kristus, tunduk di bawah otoritas-Nya dan hidup sesuai kehendak-Nya untuk kemuliaan Allah. Ciri khas sekolah Kristen adalah melaksanakan tugas dan fungsinya dengan menekankan nilai-nilai iman Kristen untuk mewarnai proses belajar-mengajar, sehingga dalam setiap materi yang disampaikan dan dalam komunitas sekolah Kristen, nilai-nilai tersebut menjadi nyata. Hal ini yang tidak dimiliki oleh sekolah-sekolah bukan Kristen.
