Vocational Education in the Fourth Industrial Revolution: Education and Employment in a Post-Work Age
by James AvisThis book examines the concept of the fourth industrial revolution and its potential impact on vocational education and training. Broadly located in a framework rooted in critical/radical theory, the book argues that the affordance of technologies surrounding the fourth industrial revolution are constrained by their location within a neoliberal, if not capitalist, logic. Thus, the impact of this revolution will be experienced differently across European regions as well as low and middle income economies. In order to break this impasse, this book calls for a politics based on non-reformist reforms, premised on an aspiration towards a socially just society that transcends capitalism.

Voice Attractiveness: Studies on Sexy, Likable, and Charismatic Speakers (Prosody, Phonology and Phonetics)
by Benjamin Weiss Jürgen Trouvain Melissa Barkat-Defradas John J. OhalaThis book addresses various aspects of acoustic–phonetic analysis, including voice quality and fundamental frequency, and the effects of speech fluency and non-native accents, by examining read speech, public speech, and conversations. Voice is a sexually dimorphic trait that can convey important biological and social information about the speaker, and empirical findings suggest that voice characteristics and preferences play an important role in both intra- and intersexual selection, such as competition and mating, and social evaluation. Discussing evaluation criteria like physical attractiveness, pleasantness, likability, and even persuasiveness and charisma, the book bridges the gap between social and biological views on voice attractiveness. It presents conceptual, methodological and empirical work applying methods such as passive listening tests, psychoacoustic rating experiments, and crowd-sourced and interactive scenarios and highlights the diversity not only of the methods used when studying voice attractiveness, but also of the domains investigated, such as politicians’ speech, experimental speed dating, speech synthesis, vocal pathology, and voice preferences in human interactions as well as in human–computer and human–robot interactions. By doing so, it identifies widespread and complementary approaches and establishes common ground for further research.

Voice over IP Networks: Quality of Service, Pricing and Security
by Ling Wang Pramode K. VermaThis book addresses three important issues in VoIP networks: Quality of Service, pricing and security. In addressing Quality of Service (QoS), it introduces the notion of delay not exceeding an upper limit, termed the bounded delay, to measure the Quality of Service in VoIP networks. Queuing models are introduced to measure performance in terms of bounded delays. Closed form solutions relating the impact of bounding delays on throughput of VoIP traffic are provided. Traffic that exceeds the delay threshold is treated as lost throughput. The results addressed can be used in scaling resources in a VoIP network for different thresholds of acceptable delays. Both single and multiple switching points are addressed. The same notion and analysis are also applied on jitter, another important indicator of the VoIP QoS This book also develops a pricing model based on the Quality of Service provided in VoIP networks. It presents the impact of quality of VoIP service demanded by the customer on the transmission resources required by the network using an analytical approach. In addition, it extends and applies the delay throughput analysis developed for VoIP networks in assessing the impact of risks constituted by a number of transportation channels, where the risk associated with each channel can be quantified by a known distribution. Finally, the book explores areas for future research that can be built on the foundation of research presented.

Voice over LTE: EPS and IMS Networks (Iste Ser.)
by André PérezVoice over LTE (Long Term Evolution) presents the mechanisms put in place in 4G mobile networks for the transportation of IP packets containing voice data and telephone signaling, as well as the technologies used to provide a telephone service in the IMS (IP Multimedia Sub-system) network. Despite the difficulty connected to the handover of the 4G network to the 2G/3G network, a telephone communication will not be established on the 4G network. This book analyzes the technologies that have been put in place, such as CSFB (Circuit Service FallBack), an interim solution that enables a mobile connected to the 4G network to receive an alert transmitted by the 2G/3G network. The book also goes on to develop the SIP (Session Information Protocol) on which the telephone signaling transferred by the 4G network is based, the IMS network that provides the service and defines the routing, the SRVCC (Single Radio Voice Call Continuity) mechanism that maintains communication and the TAS (Telephony Application Server) that supplies supplementary services. Contents 1. The EPS Network. 2. The LTE Interface. 3. The CSFB Function. 4. SIP and SDP Protocols. 5. The IMS Network. 6. Telephone Services. 7. The SRVCC Function.

Voices from Chernobyl: The Oral History of a Nuclear Disaster
by Svetlana AlexievichOn April 26, 1986, the worst nuclear reactor accident in history occurred in Chernobyl and contaminated as much as three quarters of Europe. Although the Soviet government claims that only 31 people died as a result, the aftermath of the event is astounding. Over 485 villages are lost, and approximately 2.1 million people (including 700,000 children) live on contaminated land. There is no official record of how many thousands have died, but thousands of children have been born with catastrophic birth defects. Countless others suffer ongoing health problems resulting from their exposure to radiation. [Translated by Keith Gessen]<P><P> Svetlana Alexievich won the 2015 Novel Prize for Literature.
Voices from History: Essex Land Girls
by Dee GordonAs much as 70 per cent of Essex is agricultural, and given its proximity to the capital it is not surprising that so many members of the Women’s Land Army found themselves on Essex farms and in Essex fields during the two world wars, doing their bit to make sure that Britain did not starve. This book not only includes interviews with some of the last surviving land ‘girls’ but also contains a wealth of material unearthed in diaries, letters and in the stories handed down from one generation to the next about women in Essex who were, literally, wearing the trousers. They were not all local girls, and many arrived from the cities never having seen a cow or a tractor before. But the British spirit persevered, and the wit and camaraderie that served us so well during those tumultuous years shines through in every story.
Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming
by Malcolm CairnsThis handbook of locally based agricultural practices brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Environmentalists have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, a growing body of evidence indicates that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment. Moreover, these external solutions often fail to recognize the extent to which an agricultural system supports a way of life along with a society's food needs. They do not recognize the degree to which the sustainability of a culture is intimately associated with the sustainability and continuity of its agricultural system. Unprecedented in ambition and scope, Voices from the Forest focuses on successful agricultural strategies of upland farmers. More than 100 scholars from 19 countries--including agricultural economists, ecologists, and anthropologists--collaborated in the analysis of different fallow management typologies, working in conjunction with hundreds of indigenous farmers of different cultures and a broad range of climates, crops, and soil conditions. By sharing this knowledge--and combining it with new scientific and technical advances--the authors hope to make indigenous practices and experience more widely accessible and better understood, not only by researchers and development practitioners, but by other communities of farmers around the world.
