Published: January 2021

The development of technology is currently getting more advanced and growing faster, especially in the field of information technology. The existence of houses in the vicinity of public facilities is very desirable and beneficial for newcomers to a new area. One of the public facilities that usually have boarding is a university or college. Students who study at a university do not only come from within the city but also come from outside the region. However, most students from outside the region have difficulty choosing boarding or rented houses due to limited information. Limited information about the facilities and the inaccuracy of boarding houses becomes a difficulty at the beginning for those who are new students. With the advancement of information technology, it can answer the need for finding a boarding house, and will be very helpful both from the side of the owner and tenant. To solve complex problems, you can use the K-Means Clustering and Hierarchical Clustering algorithm models that are optimized with naïve Bayes. The final result of this study is that the K-Means and naïve bayes accuracy values ​​are higher with 90.82% accuracy, 90.56% precision, 90.68% recall and longer time that is 10 seconds, while for hierachical and naïve values. Bayes got 88.02% accuracy, 87.82% precision, 88.00% recall and 7.6 seconds faster time

Published: January 2021

Using methods comparable to those used previously to test closely-related taxa (Pan troglodytes and Macaca mulatta), our aim was to better understand how gorillas (Gorilla gorilla gorilla) and Japanese macaques (M. fuscata) learn sequences. Using a disappearing-type simultaneous chain, we trained five gorillas and eight macaques on a two-item list of colored stimuli presented via touchscreens. There was no difference across species in the number of trials required to learn the two-item list. We added a third item to the list as each subject reached criterion. We then analyzed the subjects’ first 30 trials with the three-item list and found that the rate of successfully sequencing the list varied by subject but not by species. In their first 30 trials of the three-item list, subjects selected the second item correctly only at chance, suggesting they had only encoded the first symbol when learning the two-item list. One gorilla, tested on longer sequences, showed similar responses: when first presented with a newly-lengthened list, he only selected the penultimate item at chance levels. Thus, the primates’ errors with newly-lengthened lists is suggestive of the chaining theory of learning. These results highlight similarities in list learning of these two distantly-related primate species as well as the clear intra-species variation in learning.

Published: January 2021

Response inhibition is a behavioural skill that is important for flexible behaviour and appropriate decision making. It requires the suppression of a prepotent, but inappropriate action, in order to achieve a more advantageous outcome. Response inhibition has been tested in many animal species using the cylinder task. This task requires the self-driven inhibition of an impulse to obtain a visible food reward via a detour, rather than a direct but blocked route. We have shown previously using the stop-signal task that sheep can successfully interrupt an already-started response, if a reward is going to be restricted. However, it is not known if sheep can show self-driven response inhibition in a task that provides a reward independent of performance. Here we tested two groups of sheep on the cylinder task (11 Lleyn sheep: aged 8 months; 8 Welsh mountain sheep aged ~8 years old). Sheep were trained using an opaque cylinder and all sheep successfully learned the task. When response inhibition was tested using the transparent cylinder, all sheep performed significantly better than chance, but the older sheep showed a reduced number of correct responses compared to the young sheep (72.5±5.0% and 86.4±4.3% respectively). The results show that sheep have a mechanism for self-regulating their actions in order to retrieve food faster.
Assessing Direct Marketing Effectiveness at a Retailer’s: a Mixed-Effects Model of
Heterogeneous Responsiveness to Personalized Promotions
Authors: Pedisic Roko
Published: January 2021

This study proposed a mixed linear modeling framework for revealing the average
treatment effects of coupon promotions as well as for figuring out what kind of
customers are more responsive to coupon promotions. The analysis used detailed
data on 2,469 households who are frequent shoppers at a retailer over one year. A
series of models starting from fixed parameters OLS regression to more flexible
random coefficient models were built. The results showed that receiving more
coupon promotions does not lead to higher spending among households. None of
the available demographic characteristics was significantly linearly related to the
responsiveness to coupon promotions according the initial model with cross-level
interaction terms. However, exploratory analysis of random slopes with the help of
a regression tree allowed to correct the specification, which allowed confirming that
people aged 25+ with annual household income exceeding $25,000 are more
responsive, yet their response is insignificantly different from zero.

Published: January 2021

In the present IT age, we are in need of fully automated industrial system. To design of Data Acquisition System (DAS) and its control is a challenging part of any measurement, automation and control system applications. Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. To move to highspeed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backwardcompatible. Great stride have been made in promoting Ethernet use for industrial networks and factory automation. The Web based distributed measurement and control is slowly replacing parallel architectures due to its non-crate architecture which reduces complexities of cooling, maintenance etc. for slow speed field processing. A new kind of expandable, distributed large I/O data acquisition system based on low cost microcontroller based electronic web server[1] boards has been investigated and developed in this paper, whose hardware boards use 8-bit RISC processor with Ethernet controller, and software platform use AVR-GCC for firmware and Python for OS independent man machine interface. This system can measure all kinds of electrical and thermal parameters such as voltage, current, thermocouple, RTD, and so on. The measured data can be displayed on web pages at different geographical locations, and at the same time can be transmitted through RJ-45 Ethernet network to remote DAS or DCS monitoring system by using HTTP protocol. A central embedded single board computer (SBC) can act as a central CPU to communicate between web servers automatically.

Evaluation of Supplier Selection in Manufacturing Industries using Grey Relational Analysis- A Case Study
Authors: K Veera Bahadur Aravind Reddy , Reddy Saras Chandra T , Rajyalakshmi G.
Published: January 2021

Selection of supplier is one of the most critical activities performed by the organizations because of its strategic importance. Over the years a number of quantitative approaches have been applied to supplier selection problems. The selection process is commonly based on their previous performance records, so the ranking determines which supplier will get their supply contract. However a survey on current evaluation methods shows that they are all less objective and lack accurate data processing. These evaluation criteria often conflict, however and it is frequently impossible to find a supplier that excels in all areas. In addition some of the criteria are quantitative and some are qualitative. Thus a methodology is needed that can capture both subjective and objective evaluation measures. In this paper, we presented AHP and Grey Relational Analysis to establish a complete and accurate evaluation model for selecting suppliers based on multiple criteria and places the order quantities among them for a spinning industry

Authors: Lopez Jaifred Christian F. , Sales Reneepearl Kim P. , Regis Regin George Miguel K. , Reyes Katherine Ann V. , Ho Beverly Lorraine C.
Published: January 2021

Background and Objective. Research plays an important role in generating new knowledge that could improve health outcomes when translated into action. As such, there must exist a supportive research policy environment that facilitates the provision of necessary resources and sustainably ensures an appropriate number of skilled researchers buttressed by institutions. These, in turn, are envisioned to provide facilities, information systems, financial grants, and avenues for career development and collaboration. This study aims to analyze factors in the current policy environment that makes health research possible in the Philippines.

Methods. Qualitative exploratory design was used to characterize the Philippine health research environment. Guided by Adamchak's framework on policy environment, a content review of 39 policy documents (1991 to 2018) by the four core agencies of the Philippine National Health Research System was conducted. Seven elements of the policy environment were described.

Results. The policies analyzed in this study mainly addressed the legal, political, cultural, economic, and ecological elements of the policy environment. Policies that support the demographic and technological elements are lacking, in that these leave out details that are essential for capacity building and use of research output. A cross-cutting effort to resolve gaps may be necessary.

Conclusion. Several factors continuously affect the environment in which policy is developed. There is room for improvement in terms of showcasing the government’s regulatory quality and independence from political pressure. Equal attention must also be paid to human capital development, innovation partnerships, and mechanisms to improve knowledge impact, absorption, and utilization.

Authors: Luna Imelda A.
Published: January 2021

Objectives. This is a descriptive study to determine the origin of abnormal obturator arteries, the drainage of abnormal obturator veins, and if any anastomoses exist between these abnormal vessels in Filipino cadavers.

Methods. A total of 54 cadaver halves, 50 dissected by UP medical students and 4 by UP Dentistry students were included in this survey.

Results. Results showed the abnormal obturator arteries arising from the inferior epigastric arteries in 7 halves (12.96%) and the abnormal communicating veins draining into the inferior epigastric or external iliac veins in 16 (29.62%). There were also arterial anastomoses in 5 (9.25%) with the inferior epigastric artery, and venous anastomoses in 16 (29.62%) with the inferior epigastric or external iliac veins. Bilateral abnormalities were noted in a total 6 cadavers, 3 with both arterial and venous, and the remaining 3 with only venous anastomoses.

Conclusion. It is important to be aware of the presence of these abnormalities that if found during surgery, must first be ligated to avoid intraoperative bleeding complications.
Urban Trees and Environmental Variables: Relationships in a City of Central Chile

Published: January 2021

We identified relationships between ecosystem services provided by trees and environmental variables, including temperature (°C at ground level and 1.5 m), relative humidity (%), particulate matter (PM10, maximum and average), noise (dBA), and ultraviolet radiation (UV at 1.5 m). This study was carried out in Talca, Chile, a mid-sized city. Measurement locations were selected in three areas based along three main avenues in the center of the city during three different seasons and three different schedules of day, generating 15,515 data in total. In circular plots, with 8 meter radiuses, measurements were recorded at the center and at a point on the perimeter. A correlation matrix was calculated and an ANOVA was conducted with canopy cover, schedule of day, and season as variation sources. The results show a high dispersion, and the correlation matrix that canopy coverage has a weak relationship with variables was studied. The results of the ANOVA showed the least number of significant differences associated with the canopy cover, schedule of day, and season, which showed significant differences for all variables. Tree coverage showed significant differences for all variables using the Tukey Test, with the exception of minimum noise. Plots with greater coverage were associated with increases in the particulate matter and relative humidity and decreases in maximum noise, temperature, and ultraviolet radiation. During mornings, the highest measurements of particulate matter, noise, and relative humidity were reported, whereas temperature maximums occurred at mid-day. The results confirm the importance of urban trees, specifically the canopy coverage, in mitigating negative environmental aspects in urban areas.
The Effect of a Heat Wave on Urban Tree Pests in Melbourne, Australia: Examples that May Inform Climate Change Tree Management
Authors: Moore G.M. , Lefoe G.
Published: January 2021

"Climate change will have profound deleterious effects on many trees in urban environments; however, as in any biological system undergoing change, there will be benefits. On 7 February 2009, the Australian city of Melbourne experienced its hottest day on record (46.4 °C [115.5 °F]) after a heat wave. In the days that followed, the foliage of native Australian mistletoes, Amyema miquelii and A. pendula, growing on Eucalyptus camaldulensis were observed to lose their green color and turn gray. In large numbers, the mistletoes can cause significant stress, leading to tree death. In the aftermath of the record hot day, large numbers of mistletoes died, and 5 years later the level of mistletoe infestation remained low. On the afternoon of 7 February 2009, tens of thousands of elm leaf beetles, which heavily graze the mature elms of Melbourne (Ulmus procera and U. × hollandica), were found dead under the canopies of street trees, and numbers remained low for at least 5 years thereafter. Similarly, psyllids, Mycopsylla fici, and infestations of Ficus macrophylla, which can seriously defoliate trees, fell from high to undetectable levels in the month following the heat wave. The effects of heat waves and very high temperature days have significant implications for those managing pests in urban forests. Pest control programs were unnecessary in the immediate aftermath of the heat wave and hot days and for up to 5 subsequent years. This has positive implications for tight tree management budgets, but could also lead to a discontinuation of pest monitoring and control programs. Such an approach could see a return to high levels of infestation.

Urban afforestation requires management to ensure its sustainability within the city, and urban pruning waste is generated regularly throughout the year. This paper analyzed the time series of the urban pruning waste volume for João Pessoa (Northeast Brazil) from January 2008 to December 2014, with the objective of determining the volume of urban pruning waste generated and adjusting it to a forecast model. The models studied were part of the ARIMA (Autoregressive Integrated Moving Average) Family. The main results indicated that the ARIMA family models presented satisfactory results for the forecast, and ARIMA (0,1,4) was the model that provided the best forecast for 2014. This study contributes with a better understanding of the pattern and amount of urban pruning waste generated in João Pessoa and could assist the future orientation of municipal public policies.
A Literature Review of Resilience in Urban Forestry
Authors: Huff Emily , Johnson Michelle , Roman Lara , Sonti Nancy , Pregitzer Clara , Campbell Lindsay , McMillen Heather
Published: January 2021

Urban forests provide many benefits to residents and may also improve cities’ resilience, the overall capacity to recover from anthropogenic and natural disturbances. Resilience is often considered from an ecological, social, or social-ecological perspective. In this literature review, we synthesize past studies (n = 31) to explore resilience in urban forests and green spaces and to understand how social or ecological perspectives have been considered. We found studies that combine resilience and urban forests have been increasing over time. Definitions of both resilience and urban forests are highly variable, but generally the studies increasingly focus on a social-ecological systems approach. The most common theoretical framework applied to understanding urban forests and resilience is a risk and vulnerability assessment approach. Studies were spread across geographies, with some concentration near major research stations and universities with scientists who specialize in resilience and urban green spaces. As more attention is focused on the role of green infrastructure in contributing to urban resilience, we encourage the adoption of consistent definitions, theories, and indicators.
The Benefits of Tree Shade and Turf on Globe and Surface Temperatures in an Urban Tropical Environment
Authors: Ow Lai Fern , Ghosh Subhadip , Lokman Mohd Yusof Mohamed
Published: January 2021

The process of urbanisation increases temperature and alters the thermal comfort in cities. Urban heat islands (UHIs) result in the rise of ambient temperatures. For example, in the densely populated island state of Singapore, the UHI intensity was some 4.5 °C. Such elevation in heat can negatively impact outdoor thermal comfort and may give rise to serious health problems. The present study investigated the benefits of trees and turf as mitigation strategies for urban areas. Short- and long-term observations were made for surface and globe temperatures over smaller plots of vegetation and hard surfaces involving tree shade and full sun. Similar observations were investigated over a larger extent of vegetation across concrete, asphalt, and turf within an urban park setting. The presence of turf and shade from trees greatly affected surface temperatures, and the effect was most pronounced when both were present. The presence of turf reduced surface temperatures by up to 10 °C, while tree shade led to a 12 °C reduction. Globe temperatures showed that the presence of turf and shading reduced temperatures between 5 and 10 °C. These results suggest that turf and trees can effectively cool surfaces and improve outdoor thermal comfort. The results of this study can be applied to urban planning of greenery and can be used as a reference for other tropical cities with similar climates that are also working to develop mitigation measures to improve the liveability of their cities.
Evaluation of Stem-Injected TREE-äge® (4% Emamectin Benzoate) for Protecting Western White Pines (Pinus monticola) from Mountain Pine Beetle (Dendroctonus ponderosae Hopkins)(Coleoptera: Curculionidae: Scolytinae)
Authors: Doccola Joseph , Smith Sheri , Fischer Joseph , Strom Brian
Published: January 2021

The protection of high-value trees against bark beetles and the development of alternatives to bole sprays is a priority for the tree manager. The objective of this study was to evaluate stem-injected TREE-äge® (emamectin benzoate [EB]) as a protective treatment for western white pines (Pinus monticola Dougl. ex D. Don) against mountain pine beetle (MPB, Dendroctonus ponderosae Hopkins). Treatment efficacy was based solely on tree mortality as per Shea protocols (i.e., ≥ 60% check vs. ≤ 20% treated tree mortality). Our first experiment was installed in 2007 and included trees stem-injected with TREE-äge and untreated controls. Bole application of S-(-)-verbenone and green leaf volatile (GLV) blend was included for observational comparison. Pressure from MPB was heavy, as indicated by the number and timing of control tree mortality (90%). Strip attacks by MPB in TREE-äge trees indicated that the impacts of EB, and by inference its distribution, were inconsistent. In 2009, the injection protocol was revised to improve EB distribution in the phloem via closer injection points. In the 2009 TREE-äge-treated trees, adult beetle mining stopped when they contacted phloem and was insufficient to cause tree death by girdling. Blue-stain fungi colonized the sapwood of trees in both studies. Isolates from autopsied trees treated with TREE-äge alone were subsequently identified as Grosmannia clavigera and Leptographium longiclavatum (Ophiostomatales: Ascomycota), species that can incite tree mortality. In 2013, we revised our protocol to include GLV plus verbenone or propiconazole with TREE-äge, wherein these treatments proved effective in protecting trees against MPB and their associated pathogenic fungi.

Published: January 2021

A novela O gato e a revolução, de Alcy Cheuiche, foi publicada em 1967 e, já no ano seguinte, depois de instituído o AI5, foi censurada e impedida de chegar aos leitores. Este trabalho pretende apresentar uma reflexão crítica sobre as funções sociais desempenhadas pelas diversas personagens na novela, destacando dois discursos notadamente perceptíveis no contexto de produção da obra e estetizados por meio dos enfrentamentos ideológicos apresentados nos diálogos da narrativa: a) o discurso comunista e b) o discurso reacionário. Para lograrmos êxito na nossa pesquisa, utilizamos uma abordagem metodológica que principiou pela fortuna crítica acerca do conceito de ideologia proposto por Eagleton em Marxismo e crítica literária e com o aporte teórico que considerou o modelo de análise literária proposta por Antonio Candido, na obra Literatura e Sociedade.

Authors: Munar Munar
Published: January 2021

Teknologi yang semakin canggih saat ini, membuat banyak anak lebih suka menggunakan teknologi dalam menonton video, bermain game dan bersosialisasi melalui media,tetapi dengan kemudahan teknologi saat ini, mereka lebih suka dengan budaya asing daripada budaya sendiri. Kebiasaan ini sangat erat kaitannya dengan aktivitas sehari hari yang selalu menggunakan HP pintar melalui jaringan internet.Begitu juga dalam hal pengenalan budaya Acehbagi anak-anak sekolah maupun luar sekolah masih sangat kurang minat saat ini. Pembuatan aplikasi ini merupakan salah satu solusi untuk memberikan pengetahuan tentang  budaya nya sendiri (Budaya Aceh). Dengan adanya aplikasi ini diharapkan anak-anak lebih mengenal budaya nya sendiri di banding budaya asing.Dengan demikian dapat menimbulkan rasa cinta terhadap daerah nya sendiri. Aplikasi yang dirancang adalah sebuah aplikasi pengenalan budaya yang terdiri dari berbagai menu untuk memudahkan si user membuka aplikasi ini, dengan menggunakan metode pengembangan perangkat lunak waterfall yaitu perencanaan sistem, desain sistem, penulisan kode, pengujian sistem dan pemeliharaan yang baik agar dapat bermanfaat bagi pengguna.

Faculty Perceptions of the Factors Influencing Success in STEM Fields
Authors: Gandhi-Lee Eshani , Skaza Heater , Marti Erica , Schrader PG , Orgill MaryKay
Published: January 2021

The recent decline in the number of graduates in the fields of Science, Technology, Engineering and Mathematics (STEM) has significant implications for the nation’s economic and societal well-being (PCAST, 2012). Because university faculty members’ interactions with students—both in and out of the classroom—have a significant impact on student recruitment and retention and because faculty beliefs have a significant impact on faculty practices (Astin & Astin, 1992), we have interviewed university faculty members in order to examine their perceptions of successful STEM students. Here, we report faculty members’ perceptions of the characteristics of successful tertiary STEM students, as well as their perceptions of the major obstacle to student success in STEM courses and programs of study. While faculty perceptions of the characteristics of successful STEM students generally align with the research literature, faculty did not mention experiences or instructional strategies they could implement in their classrooms to help students develop these characteristics. The results of the current study could inform the design of faculty professional development to ensure that faculty are aware of the various ways they can support student success in STEM fields.
STEM from the perspectives of engineering design and suggested tools and learning design
Authors: Ting Yu-Liang
Published: January 2021

STEM is an educational concept about which little consensus has been reached as to what it is, and how it can be taught in schools. This study provides a snap shot of prominent contemporary research results contributing to better understanding of STEM and its implementation in education. In addition, this study tries to tackle an issue that school science has traditionally been built around well defined problems for learning purpose. As most real-world problems are ill-defined, this study proposes to implement the notion of STEM to help students acquire real-world problem-solving skills by engaging them in an engineering design process, in which students use the technology tools of graphic-based programming. The proposed learning practice is experiential task-based learning, in which students are forced to apply and acquire related science and mathematics knowledge during their engineering design process. It is hoped that related rationales and discussions will stimulates researchers and educators to adopt or tailor their own learning designs for the current generation of youngsters and promote the quality of teaching and learning in STEM.
A Highly Structured Collaborative STEAM Program: Enacting a Professional Development Framework
Authors: Bush Sarah B. , L. Cook Kristin , Ronau Robert N. , Rakes Christopher R , Mohr-Schroeder Margaret J. , Saderholm Jon
Published: January 2021

This paper reports on a highly-structured Mathematics-Science Partnership (MSP) professional development (PD) program focused on the integration of science, technology, engineering, arts, and mathematics (STEAM) in elementary mathematics and science. With a support system including higher education STEAM education and content faculty, community informal learning partners, an external evaluation team, school administrators, and expert STEAM teachers, twenty-five teachers and five STEAM instructional coaches met together for whole-group PD as they developed and then implemented integrated STEAM problem-based inquiries in their classrooms. This paper describes how the PrimeD framework (Rakes, Bush, Ronau, Mohr-Schroeder, & Saderholm, 2017; Saderholm, Ronau, Rakes, Bush, & Mohr-Schroeder, 2017) guided the STEAM PD program through a collaborative and reflective process.
Responding to the Demands of the STEM Education Agenda: The Experiences of Primary and Secondary Teachers from Rural, Regional and Remote Australia
Authors: Fraser Sharon , Beswick Kim , Crowley Suzanne
Published: January 2021

In recent years STEM education has been the focus of Australian government funding initiatives, policy and curriculum development at the national and state levels and a key driver of school innovation. Principals, teachers and students have been called upon to develop their capability and interest in the individual STEM discipline subjects or to engage in interdisciplinary STEM activities. Much of the focus on STEM has been driven by a national agenda informed by the needs of industry, and research that indicates that the students graduating from schools and universities today with STEM qualifications will not be sufficient for society’s needs. While the agenda encompasses more than individual teachers or schools, it is teachers who are at the forefront of its implementation in classrooms. In this paper we report on the perceptions of teachers about issues impacting on the effective teaching of STEM in rural, regional and remote Australia, and strategies they use to overcome issues/barriers and building the confidence and capacity of STEM teachers. Based on these, the paper reports some potential solutions to the issues faced by schools in rural, regional and remote Australia addressing the demands of the STEM Education focus.
STEM and STEAM and the Spaces Between: An Overview of Education Agendas Pertaining to ‘Disciplinarity’ Across Three Australian States
Authors: MacDonald Abbey , Hunter Jane , Wise Kit , Fraser Sharon
Published: January 2021

This article presents an overview of how interdisciplinary education agendas are being interpreted and enacted within three Australian states: New South Wales, Tasmania and Victoria. A comparative discussion is offered to ascertain the common and contrasting inhibitors and enablers of these agendas, specifically approaches to STEM and STEAM across the three states. Consideration is given to the priorities espoused in current State and Federal policy agendas. The article explores how disciplinary acronyms such as STEM and STEAM are being mobilised to empower or exclude particular disciplines, and how this implicates upon enactment of the three dimensions of the Australian Curriculum. By focusing on the contested spaces between these disciplines, the distinctiveness and potential of various interdisciplinary agendas can be better understood. In turn, ways of recognising, embracing and prioritising different forms of disciplinary knowledge can be identified in the spaces between disciplinary curriculum and pedagogy. These diverse ways of knowing are posited as integral to equipping young people for uncertain futures.
