Item Data

The main idea of this investigation is to identify a series of challenges and opportunities presented by telecommuting within the school system as a result of the SARS-Cov-2 pandemic. The objective of the paper is to identify key elements which are able to provide concrete assistance in building a sustainable online education system, with particular reference to Romania, as a system that can be used beyond the timeframe of the current pandemic. The methodology used for our scientific investigation is quantitative, based on an eight-item data collection instrument/questionnaire with 459 respondents (bachelor, masters, doctoral, and postdoctoral students—which makes this research a study from the perspective of the students’ perceptions) with ages ranging from 18 to 53. In terms of results, the eight items were evaluated on a Likert Scale from 1 to 5, leading to the formulation of seven hypotheses (H1 to H6), of which six were accepted and one was rejected (H7) (the questionnaire has a margin error/confidence interval of ±4.5% and a confidence level of P = 95%). We concluded from the six validated hypotheses, coupled with the one which was invalidated, that telecommuting to online education was not only successful but also garnered a system characterized by sustainability. Despite the swiftness of telecommuting to online education and the perceptions of the student population, online learning can be efficient and sustainable, in which case further government policies can only improve a system that has already been proven to work.

Near-Perfect Reconstruction Oversampled Nonuniform Cosine-Modulated Filter Banks Based on Frequency Warping and Subband MergingA novel method for designing near-perfect reconstruction oversampled nonuniform cosine-modulated filter banks is proposed, which combines frequency warping and subband merging, and thus offers more flexibility than known techniques. On the one hand, desirable frequency partitionings can be better approximated. On the other hand, at the price of only a small loss in partitioning accuracy, both warping strength and number of channels before merging can be adjusted so as to minimize the computational complexity of a system. In particular, the coefficient of the function behind warping can be constrained to be a negative integer power of two, so that multiplications related to allpass filtering can be replaced with more efficient binary shifts. The main idea is accompanied by some contributions to the theory of warped filter banks. Namely, group delay equalization is thoroughly investigated, and it is shown how to avoid significant aliasing by channel oversampling. Our research revolves around filter banks for perceptual processing of sound, which are required to approximate the psychoacoustic scales well and need not guarantee perfect reconstruction.

A novel method for ECG signal outlier processing based on autoencoder neural networks is presented in the article. Typically, heartbeats with serious waveform distortions are treated as outliers and are skipped from the authentication pipeline. The main idea of the paper is to correct these waveform distortions rather them in order to provide the system with better statistical base. During the experiments, the optimum autoencoder architecture was selected. An open Physionet ECGID database was used to verify the proposed method. The results of the studies were compared with previous studies that considered the correction of anomalies based on a statistical approach. On the one hand, the autoencoder shows slightly lower accuracy than the statistical method, but it greatly simplifies the construction of biometric identification systems, since it does not require precise tuning of hyperparameters.

Abstract One of the major telecommunication and network service providers in Indonesia is PT Indosat Tbk. During the coronavirus (COVID-19) pandemic, the daily stock price of that company was influenced by government policies. This study addresses stock data movement from February 5, 2020 to February 5, 2021, resulted in 243 data, using the Geometric Brownian motion (GBM). The stochastic process realization of this stock price fluctuates and increases exponentially, especially in the 40 latest data. Because of this situation, the realization is transformed into log 10 and calculated its return. As a result, weak stationary in variance is obtained. Furthermore, only data from December 7, 2020 to February 5, 2021 fulfill the GBM assumption of stock price return, as R t 1 * , t 1 * = 1 , 2 , 3 , … , 40 . The main idea of this study is adding datum one by one as much as 10% – 15% of the total data R t 1 * , starting from December 4, 2020 backwards. Following this procedure, and based on the 3% < p-value < 10%, the study shows that its datum can be included in R t 1 * , so t 1 * = − 4. − 3 , − 2 , … , 40 and form five other data groups, R t 2 * , … , R t 6 * . Considering Mean Absolute Percentage Error (MAPE) and amount of data from each group, R t 6 * is selected for modelling. Thus, GBM succeeded in representing the stock price movement of the second most popular Indonesian telecommunication company during COVID-19 pandemic.

Conflictual Relationship

A growing body of literature on urban and grassroots social movements is replete with case studies of citizens mobilizing against infrastructural development projects. These mobilizations, known as insurgent citizenship—the participation in alternative channels of political expression—take different forms and have various impacts. An investigation into the case of the mobilizing agenda of the Greater Bloemfontein Taxi Association (GBTA) against using a costly intermodal transport facility in Bloemfontein is aimed at highlighting the often neglected dilemma of how powerless citizens—for example, taxi owners—respond to state hegemony. Theoretically, the article is grounded in the conceptual framework of insurgent citizenship and, empirically, draws on narratives of a range of participants. The findings provide an understanding of the importance of organizational structure and leadership in the sustained insurgent action by the GBTA. It is argued that the insurgent action by the GBTA is produced mainly by—on the one hand—the conflictual relationship between government policies and practices and—on the other hand—grassroots resistance to their exclusionary and marginalizing effects. Furthermore, the findings elucidate that insurgent practice may be driven by neoliberal principles of competition, profit, and entrepreneurship.

Atualmente é preciso reavaliar o comportamento do consumidor e seus modos de consumo, pois buscando contribuir para um mundo mais equilibrado, com menos desperdício e impacto ambiental, percebe-se uma maior conscientização da sociedade acerca do que se consome. Neste sentido, este estudo possui como objetivo analisar o comportamento de consumo sustentável e compreender as similaridades e diferenças do consumo de produtos verdes de acadêmicos dos cursos de Administração de uma universidade brasileira e outra, espanhola. Para tanto, utilizou-se o método survey, com uma amostra caracterizada como não-probabilística e por acessibilidade mediante a aplicação de um questionário, que obteve o retorno de 289 respondentes. O instrumento de coleta de dados foi adaptado do estudo desenvolvido por Biswas e Roy (2015), o qual aborda a teoria dos valores de consumo, composta pelo valor funcional, valor social, valor condicional, valor ambiental e valor conhecimento. Os resultados obtidos revelam que, tanto para os acadêmicos brasileiros, quanto para os espanhóis, os constructos valor condicional e valor ambiental apresentaram as maiores médias, enquanto o constructo valor social apresentou uma média baixa. Também se observou que, por um lado, os estudantes brasileiros são mais propensos a adquirir produtos sustentáveis por sugestão de seus grupos sociais e que estão mais preocupados com o fato de que a escassez dos recursos naturais ameace o futuro das gerações posteriores. Por outro lado, os estudantes espanhóis são mais dispostos a comprar produtos de empresas que investem em questões ambientais. ABSTRACTNowadays it is necessary to reevaluate consumer behavior and consumption modes, as seeking to contribute to a more balanced world, with less waste and environmental impact, there is a greater awareness of society about what is consumed. In this sense, this study aims to analyze the sustainable consumption behavior of academics in Administration courses in Brazil and Spain, through comparative research. For this, the survey method was used, with a sample characterized as non-probabilistic and for accessibility through the application of a questionnaire, which obtained the return of 289 respondents. The data collection instrument was adapted from the study developed by Biswas and Roy (2015), which addresses the theory of consumption values, composed of functional value, social value, conditional value, environmental value, and knowledge value. The results obtained reveal that, for both Brazilian and Spanish academics, the conditional value and environmental value constructs had the highest averages, while the social value construct had a low average. It was also noted that, on the one hand, Brazilian students are more likely to purchase sustainable products at the suggestion of their social groups and that they are more concerned that the scarcity of natural resources threatens the future of later generations. On the other hand, Spanish students are more willing to buy products from companies that invest in environmental issues.

In many jurisdictions around the world, community safety and crime prevention activity is supported by interagency committees. In the Australian state of New South Wales (NSW), local government Community Safety Officers (CSOs) lead, support or participate in a range of interagency and ‘whole of government’ networks, most of which were established to support central NSW state government crime prevention and community safety initiatives. Research was conducted with the aim of exploring the CSOs’ experience of the ‘whole of government’ partnerships established to support community safety and crime prevention in NSW.[i] The findings support international research which suggests that central-local partnerships are inhibited by different agendas, responsibilities and power dynamics across different levels of government. Some of the key contextual challenges for this work include concerns about costs shifting from State to local government and about shifting State government priorities; barriers to funding and to accessing crime (and other) data; and various administrative burdens. Consequently, we argued that there is a need for formal engagement and negotiation between, on the one hand, State government agencies that steer NSW crime prevention and, on the other, community safety policy initiatives and local government. Such engagement could help overcome the perception, indeed the reality, that shifting and dumping costs and responsibilities to local government is creating a range of burdens for CSOs. [i] The authors thank the NSW Local Government Community Safety and Crime Prevention Network and the individual local government CSOs who kindly assisted and contributed to this research.

Indicators Of Success

E-government is a complex undertaking, which encompasses technological, organizational, and institutional elements. Much research in the field has looked at ICT as a valid solution to make public administration more successful. This chapter offers a richer account of the role played by ICT in transforming public sector organizations, discussing the effects ICTs have in the rationalization of administrative procedures and public sector institutional transformations. The notion of techno-institutional assemblages is introduced to offer a new theoretical ground to frame the notion of success in e-government projects. It is argued here that successful e-government policies are the one that deliver the outcomes, which have led their initiation. Accordingly, the need for new indicators of success is identified.

Education with the help of technology is deliberated as an encouraging development and means of transforming the teaching-learning model. The significant changes in use of the technology in online education has seen the emergence of the concept of massive open online courses (MOOCs). India has the world's largest youth population of about 500 million in the age bracket of 5-24 years. According to the statistics offered by Deloitte, 69% of jobs will be impacted by automation and analytical skills. Critical thinking and emotional intelligence will have a higher demand as against reading and writing by 2022. The World Economic Forum's ‘Future of Jobs 2018' report states that more than one-half of India's workforce will have to be reskilled by 2022. There is a need to make the Indian educational system globally more relevant and competitive. In this context, this chapter attempts to bring out the various aspects related to the challenges and opportunities through usage of MOOCs in technology and business education, especially in the context of the new education policy of the Government of India in 2020.
