Taschenbuch. Condition: Neu. Neuware -This book emphasizes the rising need for people to have a basic understanding of science and technology and the emphatic role they can play in shaping the AI-driven future, especially in terms of creating sustainable societies with growing job opportunities. This book highlights why a smoothly functioning society will require, but does not yet possess in critical numbers, policymakers, senior managers, government officials, and those entering the high-end of the AI-driven job market who have a shared vision and a shared understanding of how science shapes the future of sustainable societies.This book makes the case that the destiny of Homo sapiens is not just about evolutionary biology but increasingly about evolutionary knowledge. This book describes the web of knowledge where scientific theories appear as intellectual constructs, which lead to new knowledge that open opportunities for gainful human employment for the well-educated while eliminating jobsfor the less-educated by advancing AI in a predator-prey adversarial model (the logistic map), thus raising livelihood concerns across wide swathes of human population.This inevitably leads to the question, 'How should intellectual property rights, especially patents, be granted and protected when AI becomes advanced enough to invent without human intervention ' To answer this question, lawmakers, policymakers, managers, government officials, judiciary, enforcement agencies, etc., must have sufficient knowledge of how scientific theories impact modern society. After reading this book, the reader will be able to find answers to the following questions:-How do scientific theories impact modern society -What is the intellectual base on which science and technology policies are founded -Why do individuals across a population need to possess scientific knowledge -What are the rising concerns of peoplein finding sustainable employment in an AI-driven world -What is the compelling need to understand the role of patentable inventions in a world where intellectual property is wealth 176 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book explores the notion of knowing-in-practice to unravel the formation of academic managers' knowing in a community university. It considers the unique socio-historical context and institutional intricacies, such as procedures, flows, and political and power structures. Knowing-in-practice implies that knowledge is dynamic, constantly in flux, and intricately linked to the capability for action within the social context. In essence, knowledge is emergent and anchored by its material context.The role of an academic manager is distinctive, involving the concurrent practice of higher education management and teaching. Hence, academic-managers are supposed to deal with a multiplicity of activities and interpersonal relationships. This work will enhance our understanding of the constitution process of academic-managers in higher education, emphasizing the perspective of knowing-in-practice. It offers insights into the learning processes and knowing associated with academic management, contributing to the improvement of university management and leadership. Further, it contributes to the advancement of organizational studies related to learning and knowing.

Taschenbuch. Condition: Neu. Neuware -Die Diskussion um Generationenunterschiede in der Arbeitswelt ist allgegenwärtig oft geprägt von Klischees und Pauschalisierungen. Dieses Buch liefert eine fundierte, empirisch gestützte Analyse zur Frage, ob sich die Erwartungen an attraktive Arbeitgeber tatsächlich zwischen Generationen unterscheiden. Die Ergebnisse zeigen: Vieles, was als generationsspezifisch gilt, ist eher Ausdruck von gesellschaftlichem Wandel. Auf Basis einer groß angelegten Befragung von Berufstätigen aus vier Generationen werden zentrale Einflussfaktoren identifiziert, die Arbeitgeber unabhängig vom Alter ihrer Mitarbeitenden attraktiv machen. Das Buch bietet praxisnahe Empfehlungen für ein nachhaltiges Personalmanagement jenseits von Generationsmythen. 68 pp. Deutsch.

Taschenbuch. Condition: Neu. Neuware -This open access book is an integrated historical and philosophical investigation of several problematic situations that emerge from diverse areas of medical practice. These include (but are not limited to):Paying less attention to patients who are suffering with symptoms because no identifiable pathological lesion or pathophysiological process can be found.Paying too much attention to patients who are not suffering with symptoms because pathological lesions or pathophysiological processes have been found.The tendency to understand patients at risk of developing pathology as being diseased.The tendency to disregard the importance of wider societal consequences of definitions of disease and health.The book shows that many of these problems are related to what disease and health are considered to be and argues that these problems can be addressed by reconsidering the concepts of health and disease employed in practice. It argues for a pragmatic reconceptualization of health and disease that allows clinicians, researchers, and lay people to understand health and disease in many ways, depending on the specific context in which they find themselves and the problems they are trying to solve. In doing so, authors are careful to show how this pragmatism does not endorse 'silly' forms of relativism, in which knowledge is reduced to belief or to whatever people find expedient to believe. This work is relevant for philosophers and historians a well as for doctors, health policy makers and other health professionals because it addresses problems sourced from medical practice, albeit using philosophical and historical methods.

Taschenbuch. Condition: Neu. Neuware -This open access book examines the roles of municipal chief executive officers in Denmark, Finland, Iceland, Norway and Sweden. Whilst it has long been recognised that local authorities in these countries are often more autonomous than most other local authorities around the world, we still lack an integrated overview of leadership in Nordic local government, and the development of its top administrative management. This book ameliorates this lack of knowledge by providing a thorough, extensive and updated assessment of the role of municipal chief executive officers in the five Nordic states, as well as their interactions and relations with internal and external actors. Comparative in nature, it will appeal to all those interested in local and urban governance, public administration, public management, and leadership studies.

Taschenbuch. Condition: Neu. Neuware -This open access book examines the effects of global education agendas such as digitalization, innovation and entrepreneurship, education in emergencies, globalization-internationalization, diversity, and sustainability on education reforms in several countries and regions. It explores how increasing international interaction and communication tools bring along a more intense convergence in national education policies. It emphasizes that in todays' world education politicians and experts in different parts of the world follow the global agenda more effectively and increase reform initiatives. Hence, in order to understand national education policies more deeply, it is important to pay attention to their global context. It explains that education reforms in countries are heavily influenced by both national and global agendas. Chapters in this book analyze the reflections of these global agendas on educational reforms of the country/countries chosen to focus on. Chapter authors draw attention to the impacts of reforms on several aspects of education like pedagogy, curriculum, teacher training, and educational administration.

Taschenbuch. Condition: Neu. Neuware -This open access book provides fascinating insights into the incredible changes that Vietnam underwent in the long twentieth century as it transformed from an early modern kingdom to a European colony, to a divided land with opposing ideologies, and to a unified country in a globalized world. At each stage in this long century of changes, there were Vietnamese who sought to mold their society into some vision of 'modernity.' The book looks at multiple, rather than one form of modernity, and links those forms with the different political moments that Vietnam experienced, in tandem with the outside interlocutors that were maintained during those periods. As such, this book provides a holistic view of the many forms of modernity and their global links that can be found in Vietnam over the course of the long twentieth century. These multiple modernities are documented in this book, and the authors do so by bringing together the strengths of 'traditional' language-based area studies scholarship with the insights that an awareness of trans-national and global perspectives provides. Relevant to historians and researchers in the broader arena of Southeast Asian studies with a particular interest in Vietnam-its journey from past to present-this book is a must-read engagement with a country that has undergone and continues to experience, rapid transformation.

Taschenbuch. Condition: Neu. Neuware -This book examines the issues arising from British contested history by looking at how it came to be constructed, how it developed, and how attitudes over time have begun to change towards it. It considers how this narrative was first created through the writing of British history. It explores the private spaces of the court, the political places of the state, and the public places of the street. Beyond British shores this history has also been enacted through international heritage sites when objects were removed and taken back to Britain. Conclusively, it explores how the historic spaces of a maritime city, has further entrenched an already complex history of the nation. How this research brings new insights into this field is by looking at it through the lens of place, space, and the spatial turn. The underlining research questions are: What role does place and space play in historical constructions of the past How do place and space contribute to contested history How can these places and spaces be re-appropriated and reused, and endowed with new meanings 100 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book uses sociolinguistic approaches to explore how media discourse on undocumented migration informs Morocco-Spain political relations. Historically, much of the contact between these two nations has been through conquest - first through the Umayyad Caliphate taking control of the Iberian Peninsula (then called Hispania) in the 8th century, and then through Spain's occupation of northern Morocco in the 20th century. Though these historical roots have undoubtedly played a role in shaping present-day Morocco-Spain relations, migration has also become another critical element, as the majority of legally authorized migration to Spain comes from Morocco. Additionally, Morocco serves as a sojourn for much of the undocumented migration to the Spanish autonomous cities of Ceuta and Melilla, both of which are enclaves in Morocco and common entry points for North African and Sub-Saharan African immigrants. Migration to Ceuta and Melilla has therefore become a flashpoint for anti-immigration attitudes that are frequently perpetuated in political and media discourse. The author uses these cities as a case study, situating them within the wider context of both immigration-related policies and news articles in order to examine how migration is represented in Spain and Morocco. The book connects media discourse with policy discourse, and addresses how these mediums (1) co-construct anti-immigration and xenophobic ideologies, and (2) shape and are shaped by the somewhat strained relations between Spain and Morocco. This book will be of interest to students and scholars of Discourse Analysis, Sociolinguistics, Migration Studies and Migration Policy, Media Studies and Political Communication. 192 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book provides a detailed account of Julián Marías's metaphysical anthropology with the ultimate aim of offering a coherent and systematic analysis of Marías's argumentation for claiming that the conscious hope for Christian salvation through resurrection - and with it the hope that Jesus Christ did actually resurrect, and more generally the hope that Christian revelation is true - is justified not because the certainty or the likelihood that this salvation will, as a matter of fact, actually occur, but because this hope amounts to a self-affirming exercise, a conscious endorsement of human reality, and as such a sign of authenticity. 160 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book interprets the concepts, philosophies and cultural traditions of lunli (roughly construed as 'relationships and rationality') from the perspective and domain of 'dialogue civilization.' On the conceptual level, it expounds the common reference and different tenets of the Chinese lunli and the Western 'ethic', exploring the characteristics of lunli and 'ethic' in civilization history, considering notably the difference between unification of family and state and division of the two at the embryonic stage of civilization. The book draws on the lunli-oriented culture and religion-based culture to demonstrate the difference between Chinese lunli and Western 'ethic' in their respective top design and ultimate care, by exploring the issue 'What the world would be like, if there were no lunli' for the Chinese and 'What the world would be like, if there were no God' for westerners. Since lunli is the most prominent feature of 'being Chinese', or the most symbolic and interpretative Chinese cultural concept, this pivot provides a key introduction for Western readers not only to the concept itself, but also to modern day Chinese culture. 204 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Nahrung ist überlebenswichtig - Nahrungssuche und Essen wird deswegen mit Glücksempfindungen belohnt. Wir entscheiden nicht bewusst, wann und wie viel wir essen, sondern unser Gehirn reagiert unbewusst auf Hormone und auch neuronale Signale aus dem Körper. Zwei Neurotransmitter, Dopamin und Serotonin, erklären das Wechselbad der Gefühle zwischen Vorfreude und Zufriedenheit. Sie motivieren uns zur Nahrungssuche und erlauben uns anschließend, uns satt und zufrieden anderen Dingen zuzuwenden. Schokolade ist ein gutes Beispiel, um die enge Beziehung zwischen Nahrungsaufnahme, Stoffwechsel und Glücksgefühlen nachzuzeichnen - Molekül für Molekül.
