The taxi industry has changed dramatically during the last decade, as ride-sourcing applications, ride-sharing and alternative pricing schemes have emerged, either as complementing or competitive services and strategies. After some years of familiarity with such trends, it is interesting to explore where the taxi industry stands with respect to possible service innovations. This paper explores behavioral patterns of drivers, focusing on issues such as their preferred way of conducting business, and their views on introducing taxi-sharing and dynamic pricing. Data collected from a face-to-face questionnaire survey in Athens, Greece are exploited, and appropriate econometric models are developed for the purposes of the study. The analysis shows that young and/or educated drivers, as well as those who are familiar with new technologies are more willing to accept innovations in taxi services. Results from a stated choice experiment show that on average 3.5 euros is the extra charge that the taxi market would accept to offer a taxi-sharing service. However, results reveal that the value of taxi-sharing varies across different groups of drivers. Overall, findings indicate that in the years to come, competition by other services, (e.g. ridesharing) will force the taxi industry to adopt new models of operation and pricing.

Smart grid (SG) is a next-generation grid which is responsible for changing the lifestyle of modern society. It avoids the shortcomings of traditional grids by incorporating new technologies in the existing grids. In this paper, we have presented SG in detail with its features, advantages, and architecture. The demand side management techniques used in smart grid are also presented. With the wide usage of domestic appliances in homes, the residential users need to optimize the appliance scheduling strategies. These strategies require the consumer’s flexibility and awareness. Optimization of the power demand for home appliances is a challenge faced by both utility and consumers, particularly during peak hours when the consumption of electricity is on the higher side. Therefore, utility companies have introduced various time-varying incentives and dynamic pricing schemes that provides different rates of electricity at different times depending on consumption. The residential appliance scheduling problem (RASP) is the problem of scheduling appliances at appropriate periods considering the pricing schemes. The objectives of RASP are to minimize electricity cost (EC) of users, minimize the peak-to-average ratio (PAR), and improve the user satisfaction (US) level by minimizing waiting times for the appliances. Various methods have been studied for energy management in residential sectors which encourage the users to schedule their appliances efficiently. This paper aims to give an overview of optimization techniques for residential appliance scheduling. The reviewed studies are classified into classical techniques, heuristic approaches, and meta-heuristic algorithms. Based on this overview, the future research directions are proposed.

The article discusses the history of the development of the problem of using artificial intelligence systems in education and pedagogic. Two directions of its development are shown: “Computational Pedagogic” and “Educational Data Mining”, in which poorly studied aspects of the internal mechanisms of functioning of artificial intelligence systems in this field of activity are revealed. The main task is a problem of interface of a kernel of the system with blocks of pedagogical and thematic databases, as well as with the blocks of pedagogical diagnostics of a student and a teacher. The role of the pedagogical diagnosis as evident reflection of the complex influence of factors and reasons is shown. It provides the intelligent system with operative and reliable information on how various reasons intertwine in the interaction, which of them are dangerous at present, where recession of characteristics of efficiency is planned. All components of the teaching and educational system are subject to diagnosis; without it, it is impossible to own any pedagogical situation optimum. The means in obtaining information about students, as well as the “mechanisms” of work of intelligent systems based on innovative ideas of advanced pedagogical experience in diagnostics of the professionalism of a teacher, are considered. Ways of realization of skill of the teacher on the basis of the ideas developed by the American scientists are shown. Among them, the approaches of researchers D. Rajonz and U. Bronfenbrenner who put at the forefront the teacher’s attitude towards students, their views, intellectual and emotional characteristics are allocated. An assessment of the teacher’s work according to N. Flanders’s system, in the form of the so-called “The Interaction Analysis”, through the mechanism of fixing such elements as: the verbal behavior of the teacher, events at the lesson and their sequence is also proposed. A system for assessing the professionalism of a teacher according to B. O. Smith and M. O. Meux is examined — through the study of the logic of teaching, using logical operations at the lesson. Samples of forms of external communication of the intellectual system with the learning environment are given. It is indicated that the conclusion of the found productive solutions can have the most acceptable and comfortable form both for students and for the teacher in the form of three approaches. The first shows that artificial intelligence in this area can be represented in the form of robotized being in the shape of a person; the second indicates that it is enough to confine oneself only to specially organized input-output systems for targeted transmission of effective methodological recommendations and instructions to both students and teachers; the third demonstrates that life will force one to come up with completely new hybrid forms of interaction between both sides in the form of interactive educational environments, to some extent resembling the educational spaces of virtual reality.

For millennia, mankind has dreamed of creating an artificial creature capable of thinking and acting “like human beings”. These dreams are gradually starting to come true. The trends in the development of modern so-ciety, taking into account the increasing level of its informatization, require the use of new technologies for information processing and assistance in de-cision-making. Expanding the boundaries of the use of artificial intelligence requires not only the establishment of ethical restrictions, but also gives rise to the need to promptly resolve legal problems, including criminal and proce-dural ones. This is primarily due to the emergence and spread of legal expert systems that predict the decision on a particular case, based on a variety of parameters. Based on a comprehensive study, we formulate a definition of artificial intelligence suitable for use in law. It is proposed to understand artificial intelligence as systems capable of interpreting the received data, making optimal decisions on their basis using self-learning (adaptation). The main directions of using artificial intelligence in criminal proceedings are: search and generalization of judicial practice; legal advice; preparation of formalized documents or statistical reports; forecasting court decisions; predictive jurisprudence. Despite the promise of using artificial intelligence, there are a number of problems associated with a low level of reliability in predicting rare events, self-excitation of the system, opacity of the algorithms and architecture used, etc.

© 2019, © 2019 Asian Studies Association of Australia. Starting in 2012, the South Korean government has implemented a large-scale relocation of its central government agencies, which are now split between the existing capital city (Seoul) and a new administrative-capital city (Sejong). One of the most controversial aspects of the relocation has been the bureaucratic inefficiency caused by its split nature. ICT-enabled solutions, dubbed “Smart Work”, were adopted to deal with this challenge, but have not been effective in avoiding inefficiency. In this article, we argue that different forms of organisational inertia created resistance to switching from traditional work routines to Smart Work’s ICT-assisted equivalents. Various forms of inertia–psychological (anxiety around learning new technologies), cognitive (culture/norms in face-to-face work routines), technological (stickiness of pre-existing IT system), political (continued influence from elected officials), and resource allocation (success bias from previous digital government projects)–significantly influenced public managers’ work practices in Sejong. These types of inertia, we argue, have reinforced face-to-face communication rather than digital communication, on-site visits rather than video-conferencing, and fixed-time work rather than flex-work. Our findings challenge dominant views from functionalist models of digital transformation and emphasise the importance of cultural congruency between workplace norms and technophilic business processes.

Digital Economy refers to an economy which is based on digital computing technologies and can also be referred to as internet economy or web economy as the business activities are conducted through markets based on the internet or the World Wide Web. A Digital Economy also refers to the usage of various digitised information and knowledge to perform various economic activities and uses various new technologies like Internet, Cloud Computing, Big Data Analytics to collect, store and analyse information digitally. This way the modern digital economies are helping the local and regional business organisations to come out of their local boundaries and step into the global scenario to take advantages of the modern liberalisation policies of the governments along with reduced trade barriers throughout the world. This paper will study the importance of digital economy in the modern world along with the difference between the traditional economy and the digital economy and the current state of digital economy in India. This Study has been casual, exploratory and empirical in nature and the data needed for research work has been collected by using both direct and indirect method of data collection.

<p>What are the effects of using mobile devices as part of teacher professional development focused on teaching and learning the Māori language for Māori immersion educational settings? Answers to this question are explored by researching the extent to which electronic devices could be an effective strategy to address the crisis of the continuing decline of the Māori language. Another issue explored in the research is whether learners make expected gains in language proficiency through the use of mobile devices in comparison to standard face-to-face methods of language instruction.  An indigenous framework, Hei Korowai, was used to guide the research and ensure the practices used were culturally appropriate, particularly when entering into and negotiating the research project with participants. Kaupapa Māori and Māori centred approaches were also drawn on to gather data from semi-structured interviews, observations of mobile device use, online questionnaires, and Māori language proficiency tests results. Fifty two participants in total took part in the research, 46 from a PLD programme that used mobile devices and 6 from a separate PLD programme that used mainly face-to-face instruction.  Electronic forms of second language acquisition could be advantageous for learners to access audio and video content on the move and at a time, pace and place convenient for them. The capacity to have literally a library’s worth of resources, functions and internet connectivity all in one tool and at the touch of a button could also be of particular significance to users. Conversely, participant attitudes about technology, varied needs for initial and on-going training in how to operate the electronic devices, and interaction preferences were challenges experienced with utilising the device as part of the language learning and teaching process. Videos viewed on the device could also be seen as one-way learning with a lack of spiritual connection and no opportunities for discussion about content, potentially causing road blocks for learners who need extra support.  Face-to-face instruction was a preferred method for participants and the physical presence of the teacher highly valued to allow the space to pose and answer questions and receive an immediate response, which is not possible when learning via videos on a mobile device. However, there was acknowledgement of the complementary nature and value of utilising the mobile device followed by face-to-face meetings.  Evidence suggests that Māori have been quick to adopt and adapt new technologies since the arrival of the early settlers to the shores of Aotearoa. Could technology be the panacea, the cure-all for the revitalisation of the Māori language, a tool that provides access to language, culture and identity to the multitudes? This research tests the hypotheses in the context of two items of modern technology, the iPod Touch® and the iPad®.  The limitations of the research include potential bias in interpretation given the researcher’s insider position, the relatively small scale of the project, and the absence of a widely accepted theoretical framework for mobile learning. Critical questions that still remain are the implications of promoting ‘one Māori language’ for a large-scale programme and the risks in doing so for the preservation of tribal dialect and community identity. This study has, however, begun the conversation about the use of mobile devices in Māori medium educational settings, and it may contribute to an understanding of how to design technologies, media, and interactions to support learning within these settings towards innovative practices.</p>

New technologies primarily affect the lives of all people, their habits, needs, desires, but also significantly affect the demands placed on various business sectors. Discussions on the increasingly rapid development of technical-technological solutions that can be applied in the postal sector and logistics have a long history. New technologies in all areas bring a constant change in the relationship between companies and their customers, which significantly affect the quality of work and activities. In the years to come, it will be an increasing challenge for postal operators around the world, as well as for other companies, to achieve substantive communication and understanding of their customers through the application of innovative technologies. Understanding and learning about customer issues is key to offering them services that, with their precise targeting of stakeholders, quality, visibility, efficiency, and, perhaps most importantly, flexibility, will be able to meet needs that change so quickly over time. This will be possible with new technologies and innovative solutions. The paper presents a market research on the potential use of autonomous vehicles and drones in the postal sector in Bosnia and Herzegovina. The research is based on a survey questionnaire on the use of drones and autonomous vehicles in the postal sector in the segment of shipment delivery.

<p>Tasmania, one of the first locations to have communities connected to the national broadband network (NBN), provided the context within which to ask significant questions about the implications of the NBN for all levels and sectors of education. This paper reports findings from a research project that developed innovative methodology to explore the issues with 21 respondents categorised as "leaders" in the field of information and communication technology in education. The aim of the research was to conduct an audit of actual and planned implementation of new technologies in classroom teaching through in-depth interviews, to assess challenges faced in implementation and to facilitate dialogue between leaders in disparate education areas through provision of forums online and face-to-face. In this way the action research both contributed to an understanding of issues and acted as a change agent in stimulating the sharing of new approaches to what turned out to be a set of highly complex "wicked" problems. Resulting models using a causal layered approach demonstrate that whereas the NBN did not become the immediate solution to connectivity for these leaders, it provided the motivation to consider what a connected educational environment could be like.</p>
