LED Lighting for Urban Agriculture
by Toyoki Kozai Kazuhiro Fujiwara Erik S. RunkleThis book focuses on light-emitting diode (LED) lighting, mainly for the commercial production of horticultural crops in plant factories and greenhouses with controlled environments, giving special attention to: 1) plant growth and development as affected by the light environment; and 2) business and technological opportunities and challenges with regard to LEDs. The book contains more than 30 chapters grouped into seven parts: 1) overview of controlled-environment agriculture and its significance; 2) the effects of ambient light on plant growth and development; 3) optical and physiological characteristics of plant leaves and canopies; 4) greenhouse crop production with supplemental LED lighting; 5) effects of light quality on plant physiology and morphology; 6) current status of commercial plant factories under LED lighting; and 7) basics of LEDs and LED lighting for plant cultivation. LED lighting for urban agriculture in the forthcoming decades will not be just an advanced form of current urban agriculture. It will be largely based on two fields: One is a new paradigm and rapidly advancing concepts, global technologies for LEDs, information and communication technology, renewable energy, and related expertise and their methodologies; the other is basic science and technology that should not change for the next several decades. Consideration should be given now to future urban agriculture based on those two fields. The tremendous potentials of LED lighting for urban agriculture are stimulating many people in various fields including researchers, businesspeople, policy makers, educators, students, community developers, architects, designers, and entrepreneurs. Readers of this book will understand the principle, concept, design, operation, social roles, pros and cons, costs and benefits of LED lighting for urban agriculture, and its possibilities and challenges for solving local as well as global agricultural, environmental, and social issues.
LED Packaging for Lighting Applications: Design, Manufacturing, and Testing
by Sheng Liu Xiaobing LuoSince the first light-emitting diode (LED) was invented by Holonyak and Bevacqua in 1962, LEDs have made remarkable progress in the past few decades with the rapid development of epitaxy growth, chip design and manufacture, packaging structure, processes, and packaging materials. LEDs have superior characteristics such as high efficiency, small size, long life, low power consumption, and high reliability. The market for white LED is growing rapidly in various applications.

Lee de Forest
by Mike AdamsThe life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both invention and early film making; de Forest as the scientist and producer, director, and writer of the content. This book tells the story of de Forest's contribution in changing the history of film through the incorporation of sound. The text includes primary source historical material, U.S. patents and richly-illustrated photos of Lee de Forest's experiments. Readers will greatly benefit from an understanding of the transition from silent to audio motion pictures, the impact this had on the scientific community and the popular culture, as well as the economics of the entertainment industry.

The Left Hand of Data: Designing Education Data for Justice
by Matthew Berland Antero GarciaA speculative framework that imagines how we can use education data to promote play, creativity, and social justice over normativity and conformity.Educational analytics tend toward aggregation, asking what a &“normative&” learner does. In The Left Hand of Data, educational researchers Matthew Berland and Antero Garcia start from a different assumption—that outliers are, and must be treated as, valued individuals. Berland and Garcia argue that the aim of analytics should not be about enforcing and entrenching norms but about using data science to break new ground and enable play and creativity. From this speculative vantage point, they ask how we can go about living alongside data in a better way, in a more just way, while also building on the existing technologies and our knowledge of the present.The Left Hand of Data explores the many ways in which we use data to shape the possible futures of young people—in schools, in informal learning environments, in colleges, in libraries, and with educational games. It considers the processes by which students are sorted, labeled, categorized, and intervened upon using the bevy of data extracted and collected from individuals and groups, anonymously or identifiably. When, how, and with what biases are these data collected and utilized? What decisions must educational researchers make around data in an era of high-stakes assessment, surveillance, and rising inequities tied to race, class, gender, and other intersectional factors? How are these complex considerations around data changing in the rapidly evolving world of machine learning, AI, and emerging fields of educational data science? The surprising answers the authors discover in their research make clear that we do not need to wait for a hazy tomorrow to do better today.
Left to Our Own Devices: Outsmarting Smart Technology to Reclaim Our Relationships, Health, and Focus (The\mit Press Ser.)
by Margaret E. MorrisUnexpected ways that individuals adapt technology to reclaim what matters to them, from working through conflict with smart lights to celebrating gender transition with selfies.We have been warned about the psychological perils of technology: distraction, difficulty empathizing, and loss of the ability (or desire) to carry on a conversation. But our devices and data are woven into our lives. We can't simply reject them. Instead, Margaret Morris argues, we need to adapt technology creatively to our needs and values. In Left to Our Own Devices, Morris offers examples of individuals applying technologies in unexpected ways—uses that go beyond those intended by developers and designers. Morris examines these kinds of personalized life hacks, chronicling the ways that people have adapted technology to strengthen social connection, enhance well-being, and affirm identity. Morris, a clinical psychologist and app creator, shows how people really use technology, drawing on interviews she has conducted as well as computer science and psychology research. She describes how a couple used smart lights to work through conflict; how a woman persuaded herself to eat healthier foods when her photographs of salads garnered “likes” on social media; how a trans woman celebrated her transition with selfies; and how, through augmented reality, a woman changed the way she saw her cancer and herself. These and the many other “off-label” adaptations described by Morris cast technology not just as a temptation that we struggle to resist but as a potential ally as we try to take care of ourselves and others. The stories Morris tells invite us to be more intentional and creative when left to our own devices.
Legacies of Dust: Land Use and Labor on the Colorado Plains
by Douglas SheflinThe Dust Bowl of the 1930s was the worst ecological disaster in American history. When the rains stopped and the land dried up, farmers and agricultural laborers on the southeastern Colorado plains were forced to adapt to new realities. The severity of the drought coupled with the economic devastation of the Great Depression compelled farmers and government officials to combine their efforts to achieve one primary goal: keep farmers farming on the Colorado plains. In The Legacies of Dust Douglas Sheflin offers an innovative and provocative look at how a natural disaster can dramatically influence every facet of human life. Focusing on the period from 1929 to 1962, Sheflin presents the disaster in a new light by evaluating its impact on both agricultural production and the people who fueled it, demonstrating how the Dust Bowl fractured Colorado’s established system of agricultural labor. Federal support, combined with local initiative, instituted a broad conservation regime that facilitated production and helped thousands of farmers sustain themselves during the difficult 1930s and again during the drought of the 1950s. Drawing from western, environmental, transnational, and labor history, Sheflin investigates how the catastrophe of the Dust Bowl and its complex consequences transformed the southeastern Colorado agricultural economy.
The Legacy of John Waldie and Sons: A History of the Victoria Harbour Lumber Company
by Kenneth A. Armson Marjorie McleodAt the time of his death in 1907, John Waldie, founder of the Victoria Harbour Lumber Company, was identified as "the second largest lumber operator in Canada." A young Scottish immigrant who came to Wellington Square (now Burlington, Ontario) in 1842, he rose to prominence as a wealthy merchant and ship owner. In 1885 he entered the lumber business. Active in local and federal politics, and a friend of Sir Wilfrid Laurier, he invested capital in mills, people and forests.Local history and genealogical connections are part of the Waldie story, headquartered at Victoria Harbour in Simcoe County. Documentation of the forest that the company logged, their nature, amount and sizes of logs harvested with the descriptions of the forests as they are now, throws new light and shatters some of the current myths.This little-known story provides insights into days of rampant entrepreneurialism, the world of the lumber barons and the overall impact on our Ontario forests.
Legacy, Pathogenic and Emerging Contaminants in the Environment (Sustainable Water Developments - Resources, Management, Treatment, Efficiency and Reuse #7)
by Manish KumarThis is the time when legacy, pathogenic, and emerging contaminants must be talked about, understood, and dealt with together. While the geogenic contamination of the groundwater is a well-established phenomenon that is considered as legacy contaminants that risk people’s health globally, both pathogenic and emerging contaminants like various water-borne pathogens and pharmaceutical personal care products (PPCPs) are becoming imperative for their acute and chronic toxic effects. While contaminated groundwater consumption leads to skin pigmentation, hyperkeratosis, kidney damage, cardiovascular disease, and children’s overall development, poor sanitation-related pathogenic microorganisms cause a significant number of child and prenatal deaths. Simultaneously, antibiotic microbial resistance (AMR) is expected to kill 100 million people by 2050. However, there are rare texts that combine aspects of all these three under a single book cover. This book gives an understanding of the occurrence, fate, and transport of geogenic, microbial, and anthropogenic contaminants in the groundwater. It covers not only the scientific and technical aspects but also environmental, legal, and policy aspects for contaminant management in the environment under the paradigm shift of COVID-19. This book is intended to bring the focus on the natural contaminants—biotic or abiotic—in the post-COVID Anthropocene, which is illustrating a significant alteration of systems and the subsequent downstream impacts owing to globalization. This book has compiled global work on emergence, mass flow, partitioning, and activation of geogenic, emerging, and pathogenic contaminants in various spheres of environment with special emphasis on soil, sediment, and aquatic systems for enhancing the understanding on their migration and evolution for the welfare of mankind.
Legal and Ethical Challenges of Artificial Intelligence from an International Law Perspective (Law, Governance and Technology Series #46)
by Themistoklis TzimasThis book focuses on the legal regulation, mainly from an international law perspective, of autonomous artificial intelligence systems, of their creations, as well as of the interaction of human and artificial intelligence. It examines critical questions regarding both the ontology of autonomous AI systems and the legal implications: what constitutes an autonomous AI system and what are its unique characteristics? How do they interact with humans? What would be the implications of combined artificial and human intelligence? It also explores potentially the most important questions: what are the implications of these developments for collective security –from both a state-centered and a human perspective, as well as for legal systems? Why is international law better positioned to make such determinations and to create a universal framework for this new type of legal personality? How can the matrix of obligations and rights of this new legal personality be construed and what would be the repercussions for the international community? In order to address these questions, the book discusses cognitive aspects embedded in the framework of law, offering insights based on both de lege lata and de lege ferenda perspectives.

Legal Aspects of the Recovery of Areas Degraded by Mining in the International Seabed (SpringerBriefs in Law)
by Antonio Elian Lawand JuniorThis book offers an innovative approach to the recovery of areas degraded by international seabed mining, one that considers the feasibility of a standard that would allow mining in these areas in apparent antinomy with their other potential present and future uses. The book begins by identifying and explaining the legal norms that allow mining in these areas and the rights and obligations in mining exploitation concomitant to other uses of them, based on an analysis of mining operations’ duty of Recovery of Degraded Areas. It reveals an antinomy in international law, namely the compatibility of degraded areas and their various present and future uses with the mining of the international seabed. The freedom to mine these areas could destroy the least impacted biome on the planet and undermine the international law system represented by the Cultural Heritage of Mankind and the Third United Nations Convention on the Law of the Sea (“UNCLOS III”). Recovery of Degraded Areas is an obligation in mining and, as such, requires structural changes in the reading of UNCLOS III; recognizing international roles other than those related to sovereignty; projecting the law into the future; and rereading it in light of international environmental law and its instruments.

Legal Priorities in Air Transport
by Ruwantissa AbeyratneAgainst the backdrop of enormous technological strides, this book argues that the air transport industry must be constantly vigilant in its efforts to employ a legal regime that is applicable to the aeronautical and human aspects of the carriage by air of persons and goods. In this regard, safety and security are of the utmost importance, both in terms of safe air navigation and the preservation of human life. Although the International Civil Aviation Organization (ICAO) addresses legal issues through its Legal Committee, many emerging issues that urgently require attention lie outside the Committee’s purview. This book analyzes in detail the items being considered by ICAO’s Legal Committee, considers the legal nature of ICAO, and discusses whether or not ICAO’s scope should be extended. Since the limited issues currently addressed by ICAO do not reflect the rapidly changing realities of air transport, the book also covers a broad range of key issues outside the parameters set by ICAO, such as: the need to teach air law to a new generation of aviation professionals; combating cyber-crime and cyber-terrorism; the regulation of artificial intelligence; traveller identification; interference with air navigation; human trafficking; unruly passengers; climate change; air carrier liability for passenger death or injury; Remotely Piloted Aircraft Systems (drones); and the cabin crew and their legal implications.
The Legal Technology Guidebook
by Kimberly Williams John M. Facciola Peter Mccann Vincent M. CatanzaroThis book explores the transformational impact of new technological developments on legal practice. More specifically, it addresses knowledge management, communication, and e-discovery related technologies, and helps readers develop the project management and data analysis skills needed to effectively navigate the current, and future, landscapes. It studies the impact of current trends on business practices, as well as the ethical, procedural, and evidentiary concerns involved. Introducing novel interactive technologies as well as traditional content, the book reflects expertise from across the legal industry, including practitioners, the bench, academia, and legal technology consultants. All of the contributing authors currently teach aspiring lawyers and/or paralegals and have identified a gap in the available instructional material. Rapid technology advances have radically changed the way we all live and work, and the legal profession is by no means exempt from the impact of these changes. In order to better assist their clients, and to better compete on the legal market, it is imperative for lawyers to understand the ethical, functional, and business consequences of new technologies on their respective practices. This book provides the necessary content by including legal technology texts, information about novel pedagogical technologies, helpful tools for managing legal technologies and IT staff, statistical methods, tips and checklists.
