Opis:
The continuous drive towards electrified propulsion systems has been imposing ever more demanding performance and cost targets for the future power electronics, machines and drives (PEMDs). This is particularly evident when exploring various technology road mapping documents both for automotive and aerospace industries, e.g. Advanced Propulsion Centre (APC) UK, Aerospace Technology Institute (ATI) UK, National Aeronautics and Space Administration (NASA) USA and others. In that context, a significant improvement of the specific performance and cost measures, e.g. power density increase by a factor of 10 or more and/or cost per power unit reduction by 50% or better, is forecasted for the next 5 to 15 years. However, the existing PEMD solutions are already at their technological limits to some degree. Consequently, meeting the performance and cost step change would require a considerable development effort. This paper is focused on electrical machines and their thermal management, which has been recognised as one of key enabling factors for delivering high specific output solutions. The challenges associated with heat removal in electrical machines are discussed in detail, alongside with new concepts of thermal management systems. Several examples from the available literature are presented. These include manufacturing techniques, new materials and novel integrated designs in application to electrical machines.

Opis:
In this article we explore and discuss the benefits of and the challenges that arise when using qualitative methods to conduct research internationally. We firstly discuss the relationship that writers of qualitative studies have with their readers and the implications of this for writing style. This is then followed by an overview of different aspects of data collection design. Within this section we discuss research that we have conducted, as part of a variety of international projects, using two qualitative approaches: systematic documentary research and interview. We then focus on using interview as a research method. This discussion regarding using interviews is divided into two chapters. Firstly, we discuss issues of access and sampling, then the interview itself and the analysis of interview data. The final sections involve a discussion of ways in which validity and reliability can be contextualised within qualitative studies, and also a discussion on generalisability and the possibility of theory generation. We conclude with sections on ethics and possible future directions for international qualitative studies into teacher education.

Opis:
Environmental phenomena have a major impact on our daily lives. These include changes affecting the sources of life such as in the waters and air of our world, which have been degraded in purity. The term ‘smart environment’ is defined as a technology that provides many facilities and solutions for many environmental application issues related to water quality and health, air pollution, weather, radiation monitoring, waste management, natural disaster, and many other environment indicators. Smart environment sensors integrated with ‘Internet of Things’ (IoT) technology can provide a new concept in tracking, sensing and monitoring objects of environment. This can provide potential benefits leading up to the possibility of achieving a green world and a sustainable lifestyle. IoT allows environmental sensors to connect with other systems such smart phones through Bluetooth or Wi-Fi to send enormous amounts of data to the network and can allow us to have a better understanding of our surroundings and find suitable solutions for today environmental problems. In this review article, we will provide a brief conception of environment areas of study based on IoT technology and discuss the justification behind using IoT in the field of environmental studies. Moreover, we will investigate many proposed applications of environmental research based upon IoT.

Opis:
The aim of this article is to examine two treaties which are often presented by scholars as potential models for a maritime regime in the South China Sea, namely the Svalbard Treaty and the Antarctic Treaty System. The work concludes that even though both of the treaties have resolved equally complex territorial disputes, their importance as a role model for the SCS is limited due to the unique political condition in the Asia-Pacific. However, the solutions within the sphere of environmental protection and the structure of decision-making institutions developed by the abovementioned treaties present a valuable lesson and a potential example for the countries involved in the South China Sea dispute to emulate. The article argues that cooperation within environmental protection and fisheries management, as a low-profile endeavour, is easier to be put into practice than the joint development of highly contested hydrocarbon resources of the SCS. Furthermore, it can potentially lay foundation for the future high profile collaboration. The paper also presents a model of a maritime regime for the South China Sea.
Целью данной статьи является изучение двух договоров, которые часто пред- ставляются учеными в качестве потенциальных моделей морского режима в Юж- но-Китайском море, а именно Договора о Шпицбергене и Системы Договора об Антарктике. В работе делается вывод о том, что хотя оба договора разрешили одинаково сложные территориальные споры, их важность в качестве образца для подражания для СКС ограничена из-за уникальных политических условий в Азиатско-Тихоокеанском регионе. Однако решения в области защиты окружа- ющей среды и структуры институтов принятия решений, разработанные в рамках вышеупомянутых договоров, представляют собой ценный урок и потенциальный пример для подражания странам, вовлеченным в спор вокруг Южно-Китайского моря. В статье утверждается, что сотрудничество в области охраны окружающей среды и управления рыболовством, как скромное мероприятие, легче реализовать на практике, чем совместная разработка весьма спорных углеводородных ресурсов Южно-Китайского моря. Более того, это потенциально может заложить основу для будущего сотрудничества на высоком уровне. В статье также представлена модель морского режима Южно-Китайского моря.

socioeconomic changes and challenges
Opis:
There are several papers available addressing the challenges for Future Internet that result from socio-economic aspects; such challenges must be obviously taken into account when constructing and developing Future Internet. This paper, however, takes an opposite view that from the dynamics of the development of Internet itself (or Future Internet) result challenges for the socio-economic development and even for the paradigm of understanding economy; such challenges must be taken into account first, then - in a feedback loop -lead to the modification of socio-economic challenges for Future Internet. This change of perspective is necessary because the analysis of socio-economic challenges for Future Internet is typically based on a classical paradigm of equilibrium economics. While useful, this paradigm is limited and has been shown incomplete, e.g., by the recent world-wide financial and economic crisis. This paper shows that the informational revolution - including but not limited to the development of Internet - has already changed the behavior of main socio-economic agents as well as of economic markets and our understanding of them; thus, new perspectives are needed. The paper also shows that a useful perspective is that not of expected benefits from Future Internet - there are many such benefits and they will surely motivate enough economic development of Future Internet - but of socio-economic threats resulting from the dynamic development of the Internet. There are several such threats and conflicts that can be foreseen: the conflict between corporatization and governance; the conflict between direct and indirect limits to freedom; the trend to- wards elitarism inherent in Internet development dynamics versus democracy; the threat of network and computer domination over people, etc. Some of such threats and conflicts are discussed in the paper.

Opis:
Family businesses are an important part of every economy. They are characterized by long traditions that combine aspects such as trust and reliability, as well as by features such as innovativeness, foresight, long-term focus and flexibility. Both family businesses and the entrepreneurial families themselves do have some weaknesses and face current challenges like digitization, internationalization and demographic change. These issues must be kept in mind in order to constantly develop appropriate solutions that will help them survive and thrive in the market. Moreover, the high relevance of the family in a family business is associated with opportunities – for example, when a family strategy with clear values, roles and goals is defined, and a so called family business governance is developed.

Opis:
Meeting the educational needs of students currently requires moving toward collaborative electronic and mobile learning systems that parallel the vision of Web 2.0. However, factors such as data freedom, brokerage, interconnectivity and the Internet of Things add to a vision for Web 3.0 that will require consideration in the development of future campus-based, distance and vocational study. So, education can, in future, be expected to require deeper technological connections between students and learning environments, based on significant use of sensors, mobile devices, cloud computing and rich-media visualization. Therefore, we discuss challenges associated with such a futuristic campus context, including how learning materials and environments may be enriched by it. As an additional novel element the potential for much of that enrichment to be realized through development by students, within the curriculum, is also considered. We will conclude that much of the technology required to embrace the vision of Web 3.0 in education already exists, but that further research in key areas is required for the concept to achieve its full potential.

Opis:
The importance of corporate social responsibility (CSR) in nowadays business reality is constantly growing thanks to many factors, including the important promotional effort at all possible authorities levels and increasing educational effort of universities and in particular of business schools. Since there is no commonly accepted guideline/curriculum/content of social responsibility (SR) education, business schools at higher education institutions (HEIs) start to develop their own approaches on SR education.This paper aims to present the general background of CSR education with particular emphasis on its enhancements existing in EU and other countries or continents. Its ambition is also to offer a picture of CSR related educational activities launched by Polish HEIs and to present its evaluation by students. The first goal will be accomplished with the literature study and the review of initiatives publicly disclosed by the authorities, NGOs and finally by HEIs themselves. The second ambition will be completed with the outcomes of the survey conducted by the author in Gdańsk University of Technology (GUT), Faculty of Management and Economics (FME). The conclusions of this work allow to propose recommendations to be implemented in the SR education in the future.
