ICTs, Values and Social Change: The Case of Canadian Democracy
Authors: Rattle Robert
Published: June 2021

Internet and communication technologies (ICTs) are revolutionising how people communicate and connect. While these have catalyzed calls for increasing societal change, social messages, not the technologies, motivate these actions. This paper will use the case study of Canada and the application of ICTs to argue why they are no less likely to support social change in modern economies than any previous technology. Drawing on examples of federal policy changes in Canada, the paper will argue ICTs and social media can be used to suppress democracy, undermine science and expand social impacts, even where they are intended to specifically address those problems. The paper will then discuss the roles of values in social change to argue that ICTs and social media are influenced by larger societal forces and that these are often better predictors of outcomes than the application of any one technology for social change.

Law, Ethics and Electronic Commerce
Authors: Hoeren Thomas
Published: June 2021

Unlike the Internet community had expected electronic commerce does not lead to an anarchic dissolution of law. In the context of electronic trade, problems arising between users and providers can be solved, for instance by applying traditional principles of contract law. And yet, the legal dispute of Internet related facts and circumstances gives rise to a number of interesting topoi. Even though these subjects have already been considered in the past (for instance in the context of satellite technology), they only now show their specific explosive effect and diversity in the face of the electronic commerce.
Innovations and Challenges in Teaching Information Ethics Across Educational Contexts
Authors: Zimmer Michael
Published: June 2021

Renewed attention to integrating information ethics within graduate library and information science (LIS) programs has forced LIS educators to ensure that future information professionals – and the users they interact with – participate appropriately and ethically in our contemporary information society. Along with focusing on graduate LIS curricula, information ethics must become infused in multiple and varied educational contexts, ranging from elementary and secondary education, technical degrees and undergraduate programs, public libraries, through popular media, and within the home. Teaching information ethics in these diverse settings and contexts brings numerous challenges and requires new understandings and innovative approaches. In keeping with the 2011 Association for Library and Information Science Education (ALISE) conference theme of “Competitiveness and Innovation,” a diverse panel of educators and researchers were convened to foster a discussion in how to best incorporate information ethics education across diverse contexts, and how to develop innovative educational methods to overcome the challenges these contexts inevitably present. This article reports on that panel discussion and offers recommendations towards achieving success in information ethics education.
Using Information Technology to Create Global Classrooms: Benefits and Ethical Dilemmas
Authors: Bradshaw York W
Published: June 2021

The global digital divide represents one of the most significant examples of international inequality. In North America and Western Europe, nearly 70% of citizens use the Internet on a regular basis, whereas in Africa less than 4% do so. Such inequality impacts business and trade, online education and libraries, telemedicine and health resources, and political information and e-government. In response, a group of educators and community leaders in South Africa and the United States have used various information technologies to create a ?global classroom? that connects people in the two countries. University students, high school students, and other citizens communicate via Internet exchanges, video conferencing, and digital photo essays. The project has produced a number of tangible benefits and it has developed a model for reducing inequality in global education, at least for those institutions with the technological resources to participate. We also present several recommendations for how to expand the initiative and thereby increase the number of people who can benefit from it.
Value Pluralism in the AI Ethics Debate – Different Actors, Different Priorities
Authors: Rudschies Catharina , Schneider Ingrid , Simon Judith
Published: June 2021

In the current debate on the ethics of Artificial Intelligence (AI) much attention has been paid to find some “common ground” in the numerous AI ethics guidelines. The divergences, however, are equally important as they shed light on the conflicts and controversies that require further debate. This paper analyses the AI ethics landscape with a focus on divergences across actor types (public, expert, and private actors). It finds that the differences in actors’ priorities for ethical principles influence the overall outcome of the debate. It shows that determining “minimum requirements” or “primary principles” on the basis of frequency excludes many principles that are subject to controversy, but might still be ethically relevant. The results are discussed in the light of value pluralism, suggesting that the plurality of sets of principles must be acknowledged and can be used to further the debate.
The Essential Relationship between Information Ethics and Artificial Intelligence
Authors: Bester Coetzee , Fischer Rachel
Published: June 2021

This article rethinks the position of Information Ethics (IE) vis-à-vis the growing discipline of the ethics of AI. While IE has a long and respected academic history, the discipline of the ethics of AI is much younger. The scope of the latter discipline has exploded in the last decade in sync with the explosion of data driven AI. Currently, the ethics of AI as a discipline can be said to have sub-divided at least into machine ethics, robot ethics, data ethics, and neuro ethics. The argument presented here is that ethics of AI can from one perspective be viewed as a sub-discipline of IE. IE is at the heart of ethical concerns about the potential de-humanising impact of AI technologies, as it addresses issues relating to communication, the status of knowledge claims, and the quality of media-generated information, among many others. Perhaps the single most concerning ethical concern in the context of data-driven AI technology is the rise of new social narratives that threaten humans’ special sense of agency and, and this is firstly an IE concern. The article thus argues for the independent position of IE as well as for its position as the core, over-arching discipline, of the ethics of AI.

Bu çalışmada TBMM’de grubu bulunan siyasi partilerin turizm politikaları, partilerin 2018 seçim beyannameleri kapsamında analiz edilmiştir. Siyasi partilerin söylemlerindeki benzerlikler ve farklılıkları ortaya konabilmek amacıyla
siyasi partilerin turizm hedefleri, pazar hedefleri, turizm türleri, yasal düzenleme önerileri, teşvik ve yatırım önerileri gibi temalar doğrultusunda beyannameler incelenmiştir. Seçim beyannameleri incelendiğinde siyasi partilerin
turizm sektörünün ekonomik potansiyelinin farkında oldukları, ancak bu potansiyeli hayata geçirmek için farklı politika öncelikleri belirledikleri görülmektedir. Diğer partilere kıyasla turizm başlığına en geniş alanı ayıran AK
Parti seçim beyannamesinde turizm hedefleri en net ve en somut şekilde yer almakta, bu netlik AK Parti’nin diğer turizm politikası önerilerine de yansımaktadır. Muhalefet partileri arasında turizm hedeflerini en net ve somut şekilde
ortaya koyan partinin İYİ Parti olduğu görülmektedir. CHP ve MHP seçim beyannamelerinde ise turizm hedefleri dar kapsamlı ve sınırlı şekilde yer almaktadır. CHP ve MHP seçim beyannamelerinin turizm hedeflerini belirlemede yetersiz
kalması, her iki partinin diğer turizm politikası önerilerine de olumsuz şekilde yansımıştır. Siyasi partilerin turizm politikalarının ve siyasi önceliklerinin güncel gelişmeler ve diğer politika başlıklarındaki gelişmelerden etkilediğini
de unutmamak gerekir. Özellikle tüm dünyayı etkilemeye devam eden Covid-19 salgınının en ciddi şekilde etkilediği sektörlerin başında gelen turizmle ilgili siyasi partilerin politika önerilerinin de güncellenmesi gerektiği söylenebilir

Published: June 2021

This study aims to conduct analysis to determine the trend of sentiment on tweets about Covid-19 in Indonesia from the Twitter accounts overseas on big data perspective. The data was obtained from Twitter in the period of April 2020, with the word query "Indonesian Corona Virus" from foreign user accounts in English. The process of retrieving data comes from Twitter tweets by crawling the text using Twitter's API (Application Programming Interface) by employing Python programming language. Twitter was chosen because it is very fast and easy to spread through status updates from and among the user accounts. The number of tweets obtained was 8,740 in text format, with a total engagement of 217,316. The data was sorted from the tweets with the largest to smallest engagement, then cleaned from unnecessary fonts and symbols as well as typo words and abbreviations. The sentiment classification was carried out by analytical tools, extracting information with text mining, into positive, negative, and neutral polarity. To sharpen the analysis, the cleaned data was selected only with the largest engagement until those with 100 engagements; then was grouped into 30 sub-topics to be analyzed. The interesting facts are found that most tweets and sub-topics were dominated by the negative sentiment; and some unthinkable sub-topics were talked by many users.
Projection Pursuit Regression (PPR) on Statistical Downscaling Modeling for Daily Rainfall Forecasting
Authors: Putra Rio Pradani , Anggraeni Dian , Hadi Alfian Futuhul
Published: June 2021

Rainfall forecasting has an important role in people's lives. Rainfall forecasting in Indonesia has complex problems because it is located in a tropical climate. Rainfall prediction in Indonesia is difficult due to the complex topography and interactions between the oceans, land and atmosphere. With these conditions, an accurate rainfall forecasting model on a local scale is needed, of course taking into account the information about the global atmospheric circulation obtained from the General Circulation Model (GCM) output. GCM may still be used to provide local or regional scale information by adding Statistical Downscaling (SD) techniques. SD is a regression-based model in determining the functional relationship between the response variable and the predictor variable. Rainfall observations obtained from the Meteorology Climatology and Geophysics Council (BMKG) are a response variable in this study. The predictor variable used in this study is the global climate output from GCM. This research was conducted in a place, namely Kupang City, East Nusa Tenggara because it has low rainfall. The Projection Pursuit Regression (PPR) will be used in this SD method for this study. In PPR modeling, optimization needs to be done and model validation is carried out with the smallest Root Mean Square Error (RMSE) criteria. The expected results must have a pattern between the results of forecasts and observations showing or approaching the observational data. The PPR model is a good model for predicting rainfall because The results of the forecast and observation show that the results of the rainfall forecast are observational data.

Authors: Larasati Dhiar Niken , Bustaman Usman , Pramana Setia
Published: June 2021

The COVID-19 outbreak is not only talking about health crises but also social and economic crises all over the world. In Indonesia, the outbreak has shaken almost all business sectors, however it seems to bring a silver lining for e-commerce sectors since the pandemic has developed online shopping habits. During the pandemic, the impact of COVID-19 on the Indonesian economy needs to be updated from time to time to be used on quick policymaking. Therefore, big data plays an important role to provide the information relatively fast. This paper aims to describe how big data i.e., marketplace data, could be used to figure the impact of COVID-19 outbreak on micro and small retailers in Indonesia. The dataset was collected regularly from a marketplace website in Indonesia from January to June 2020. To see the changing of sales during the COVID-19 period, the sales before and after social distancing policy implementation are compared. The result showed that the online marketplace in Indonesia is dominated by micro retailers based on the number of products sold in the marketplace. The total revenue of micro retailers gives a significant increase during the pandemic. Whereas for medium retailers, the increase in total revenue is seen to be lower than micro retailers’ total revenue. It indicates a positive sign for the growth of micro retailers in the online marketplace.

Design and feasibility analysis of a solar PV array installation during the construction of high-rise residential buildings
Authors: BODDAPATİ Venkatesh , SREE RAM NANDİKATTİ Avinash , ARUL DANİEL S
Published: June 2021

Effective energy utilization is a key parameter to meet the increasing global energy demand, and this paper proposes to install a solar PV array during the construction of a high-rise building. Electrical energy auditing is an essential tool for the planning and installation of solar PV systems. The outcome of energy auditing and the space availability are subsequently utilized for planning the sequential installation of solar PV systems in the four segments of the construction process. Several challenges in harnessing and utilizing solar energy during the construction, along with the strategic utilization of solar PV energy are presented for the benefit of building owners after the completion of the construction process. A case study (seven 200 m high rise buildings and associated facilities) is considered to validate the proposed energy-efficient construction process, and the same is compared with the conventional construction process. From the comparison, a significant reduction in the power drawn from the grid during the construction process is noticed. It has been found from the simulation results that an estimated annual energy of 7377 MWh is generated from the 3.63 MW roof-top solar PV systems. Further, a techno-economic assessment of the proposed solar PV system is drawn to bring out the financial benefits to the contractor, and the owners of the newly constructed high-rise residential buildings. Embracing sustainability in buildings with energy-efficient construction practices in large construction projects can substantially minimize the impact of environmental pollution.
Numerical approximation of the hydrological time of concentration
Authors: BARRÓN FERNÁNDEZ Juan Ramón , CALVO-JURADO Carmen
Published: June 2021

The time of concentration, that is the time it takes for a single "drop of water" to move superficially from the most distant point of the watershed to the exit point, is a fundamental parameter of the hydrological analysis. Many studies have been conducted to propose empirical formulas to calculate the time of concentration. One of the best known is the Temez formula based on time series data collected in accounts in Spain with areas of less than 3,000 km2. This expression uses the main channel length as a parameter as in many works, for small slopes is approximated by the distance between the geographic coordinates between the starting and ending points, leading for larger catchments and slopes to approaches with a high error. In this work, using a proper discretization of the curve, by using polynomial interpolation methods, we improve the calculation of the length of the main channel and therefore, we provide a more reliable method for calculating the time of concentration using the Temez expression. We illustrate the proposed scheme with different numerical examples comparing the results with those provided by other methods.
Numerical investigation of influence of cross-sectional dimensions of flow channels on PEM fuel cell performance
Authors: KAPLAN Mahmut
Published: June 2021

Proton exchange membrane fuel cell (PEMFC) has acquired increasing importance because of operating at higher efficiency and producing environmentally friendly power at low temperatures over the past decade. Flow channel as a vital part of PEMFC plays a critical role for augmenting the performance of PEMFC. In this paper, a single phase, 3-D model is generated to examine impact of the channel cross-section geometry on the cell performance. 15 different simulation cases were gained by altering the flow channel width and depth from 0.2 to 1.6 mm for the fixed depth and width of 1 mm, respectively. In the base case, the channel dimensions are 1.0 mm width and depth. The results revealed that decreasing depth and width of the channel enhanced the current density thanks to increasing gas velocity in the flow channels of the anode and cathode at the expense of increased pressure drop. The cases having the channel cross-sectional dimensions of 0.2 x 0.1 mm and 0.1 x 0.2 mm (channel width x depth) enhanced the current density about 57% and 45% at 0.4 V compared to the base case. Besides, oxygen consumption and water production in the cathode side are also remarkably increased in these cases. However, the channel cross-sectional size of 0.8 x 1 mm case which increases the current density 2.5% at 0.4 V in comparison with the base case can be best option by taking into consideration pressure drop into the flow channels.

Authors: HEMADRİ Vadıraj , MANE Nikhil
Published: June 2021

The optimization of process parameters of the nanofluid preparation process for maximum stability and high heat transfer is an active and important area of research. In this work, the effect of the surfactant material, surfactant weight, and ultrasonication time are studied on distilled water-based CuO, Fe3O4, and CuO+Fe3O4 nanofluids. Taguchi L9 orthogonal array was used for the design of the experiment and 9 samples were prepared using this array. The effect of each level of process parameter on the thermal conductivity is analyzed by calculating Signal to Noise Ratio (SNR) and optimum levels of these parameters are identified. The crucial role of stability in delivering high thermal conductivity nanofluids as predicted by SNR analysis is further confirmed using Analysis of Variance (ANOVA).

As one of the oldest documented mines in Europe, Rudna Glava should be at the very top when it comes to geotourist visits in Serbia and the Balkans. The research goal is to point out the possibilities of geotourism development in this part of Serbia, while the findings aim to identify the existing problems for geotourism development in the area. Тhe study will analyze the geotourism potential of this archaeological site by using the Geosite Assessment Model (GAM), combining the main and additional values. The GAM involves grades given by experts and provides a relatively actual image of the geoheritage state based on which it is practicable to plan and enhance the activities for the observed sites. The outcomes showed that the observed site has a high score of the main, and a low score of additional values. This means that the site should be additionally protected, and included in various tourist programs.

COVID-19 is forcing a re-orientation of tourism research agendas. Emerging themes relate to ramification, transformation and adaptation. The aim of this paper is to contribute to the research cluster on adaptation by examining tourism business adaptive responses to COVID-19 through the lens of a case study destination in the global South, namely Bushbuckridge in Mpumalanga Province, South Africa. The methods implemented were qualitative, using semi-structured interviews. Data was analysed from 20 interviews conducted with enterprise owners or managers in a nature tourism destination which is one of South Africa’s tourism-dependent areas and thus most exposed to the negative impacts of COVID-19. The results show that adaptation to the crisis has been challenging because of the financial impacts experienced by these enterprises in the wake of minimal government support. The enterprise adaptive responses included staff reductions and wage cuts, adjustments towards the domestic market through price cutting and changes in marketing as well as adjusted tourism product offerings towards an emerging Black middle class domestic market. Of critical importance is the finding that these adaptive measures cannot replace the revenues formerly generated from the international tourism market. Accordingly, without a change in government policy and the availability of direct government financial support, there is a danger that in the short term the tourism product base will be diminished as many lodges and other tourism businesses are in danger of permanent closure.

Contemporary organizations need to follow their performance over a continuous period, as the short period is not enough to provide complete control. Bearing this in mind, performance measurement indicators must be reflecting the organizational strategy, not just in the short term, but also in the medium and long term. In the past, especially in industrial enterprises, a high interest in measuring organizational performance was noted. Afterward, the need for effective performance management has also gained increased recognition and interest in Higher Education Institutions (HEIs). Considering the transversal demand for management control tools, the Balanced Scorecard (BSC) gained special highlight, based on its four interlinked perspectives (financial, customer, internal processes, and learning & growth), originally developed by Kaplan and Norton. The BSC was selected for this research, as it has been already implemented by multiple HEIs, to guide managers and directors in their decisions and contribute to greater efficiency. It was, therefore, also selected for the implementation by an analyzed Portuguese higher education institution. This research aims to contribute to the empirical and practical understanding of BSC implementation in higher education, whilst providing orientation to directors and managers of HEIs. With the implementation of this tool, managers and directors can monitor the organizational performance and follow the defined strategy in the medium and long term. Based on these findings, other institutions could use this study as a guide and a benchmark.

Los portainjertos son clave en la producción de frutales leñosos, ya que influyen en la precocidad, tolerancia a plagas y enfermedades y en el vigor de las plantas. En el INTA EEA Bella Vista hay árboles adultos de híbridos que se encuentran en plena producción pero que aún no han sido evaluados como portainjertos potenciales para el sector citrícola del NEA. El objetivo del trabajo fue evaluar parámetros para la propagación de tres híbridos de cítricos con potencial uso comercial. Se evaluaron las características de árboles madre y frutos, poliembrionía, y comportamiento en almácigo. También luego de 0, 45, 90 y 180 días de almacenamiento se midió porcentaje de germinación y energía germinativa de 18 plantas de 3 híbridos procedentes de cruzamientos dirigidos: mandarino ‘Cleopatra’ [Citrus reshni Hort ex Tan.] × trifolio [Poncirus trifoliata (L.) Raf.] (Cl×Tf), ‘Citrange Troyer’ [C. sinensis (L.) Osbeck] × trifolio [P. trifoliata (L.) Raf.] × mandarino común [Citrus deliciosa Ten.] (T×C) y naranjo agrio Citrus auratium L. × mandarino ‘Cleopatra’ [Citrus reshni Hort ex Tan.] (Ag×Cl). Las plantas de menor tamaño a campo fueron las del híbrido de Ag×Cl. La combinación T×C tuvo buena cantidad de semillas y aseguró buen poder germinativo hasta 180 días almacenamiento. La alta poliembrionía de Cl×Tf aseguró la obtención de plantas nucelares en vivero.

AbstractAcademic procrastination in college students is a common phenomenon, although procrastination’s negative impacts were well known. This study aimed to examine the role of self-regulation in mediating the correlation between mindfulness and academic procrastination. Data were collected by distributing online questionnaires to college students from various universities in Indonesia (n = 305). The sampling technique used was convenience sampling. Instruments used in the research were the Mindfulness Attention and Awareness Scale, the Short form of Self-regulation Questionnaire, and the Academic Procrastination Scale. The regression and mediation analyses were held. Results showed that self-regulation partially mediated the correlation between mindfulness and academic procrastination. Increasing in dispositional mindfulness helps college students regulate themselves, thereby reducing the tendency to procrastinate. The implications and limitations of the study and suggestions for further research are discussed.Keywords: academic procrastination; college students; mindfulness; self-regulation.AbstrakProkrastinasi akademik pada mahasiswa merupakan fenomena yang umum terjadi, meskipun dampak negatif prokrastinasi telah banyak diketahui. Penelitian ini bertujuan menguji peran regulasi diri dalam memediasi hubungan antara mindfulness dan prokrastinasi akademik. Pengambilan data dilakukan melalui penyebaran kuesioner secara daring kepada mahasiswa di berbagai perguruan tinggi di Indonesia (n=305). Teknik sampling yang digunakan adalah convenience sampling. Penelitian ini menggunakan alat ukur Mindfulness Attention and Awareness Scale, Short Self-Regulation Questionnaire, dan Academic Procrastination Scale. Hasil uji regresi dan uji mediasi menunjukkan regulasi diri memediasi korelasi antara mindfulness dan prokrastinasi akademik secara parsial. Peningkatan kondisi kesadaran pada mindfulness membantu mahasiswa meregulasi dirinya, sehingga mengurangi kecenderungan untuk melakukan prokrastinasi akademik. Implikasi dan keterbatasan penelitian serta saran untuk penelitian selanjutnya didiskusikan.Kata kunci: mahasiswa; mindfulness; prokrastinasi akademik; regulasi diri.

Alat tes psikologi seperti tes minat umumnya dibuat berdasarkan teori-teori psikologi kontemporer. Hasil dari tes tersebut tentu perlu dilihat atau diuji secara empiris kesesuaiannya dengan kriteria yang diinginkan. Sejauh ini pengukuran tes minat di tingkatan Sekolah Menengah Pertama (SMP) dan Sekolah Menengah Atas (SMA) masih terbatas menggunakan tes minat penjurusan yang berbasis tes vokasi. Penelitian ini bertujuan untuk mengembangkan tes minat berbasis HOLLAND yang dapat digunakan untuk pemetaan jurusan untuk siswa SMP maupun SMA. Studi ini memiliki 248 siswa SMP dan 270 siswa SMA yang mengerjakan tiga instrumen tes yaitu tes minat HOLLAND, tes penjurusan siswa SMP dan tes penjurusan siswa SMA. Uji validitas analisa faktor konfirmatorik digunakan untuk menguji validitas konstruk alat ukur dan analisa regresi model persamaan struktural digunakan untuk mengetahui prediktor yang dominan dalam menentukan pilihan jurusan seorang siswa baik di SMP maupun SMA. Beberapa trait HOLLAND ditemukan berperan secara signifikan dan konsisten dalam menentukan jurusan bidang studi yang dipilih oleh siswa SMP dan SMA. Setiap bidang studi penjurusan memiliki trait HOLLAND yang berbeda-beda sebagai prediktornya.
