In the era of social connectedness, people are becoming increasingly enthusiastic about interacting, sharing, and collaborating through online collaborative media. However, conducting sentiment analysis on these platforms can be challenging, especially for business professionals who are using them to collect vital data. Sentiment Analysis and Knowledge Discovery in Contemporary Business is an essential reference source that discusses applications of sentiment analysis as well as data mining, machine learning algorithms, and big data streams in business environments. Featuring research on topics such as knowledge retrieval and knowledge updating, this book is ideally designed for business managers, academicians, business professionals, researchers, graduate-level students, and technology developers seeking current research on data collection and management to drive profit.

This book on biomimicry assessment tools studies the concepts of sustainability, sustainable construction practices, and the evaluation categories that constitute a sustainability assessment tool. By exploring and drawing lessons from biomimicry principles, the book provides a nature-inspired assessment tool to aid and guide the sustainable transformation of the built environment. The book encapsulates the attributes of the conceptualised biomimicry assessment tool, which is aimed at helping practitioners, regulatory bodies, and governmental and non-governmental agencies in greening the built environment. Owing to the dire need for country-specific and tailor-made tools that address developing countries' needs, this book serves as a practical reference and theoretical springboard for the development of sustainability assessment tools for the built environment. Furthermore, the book serves as a guide in navigating the path towards achieving the greening agendas of the built environment and other sectors and seeks to align the new biomimicry assessment tool with the UN Sustainable Development Goals (SDGs). It is important reading for academics, professionals and advanced students in the built environment, engineering, and sustainable development.

Many approaches have been undertaken to mitigate global climate change, including the movement away from fossil fuels. Fossil Free Fuels: Trends in Renewable Energy examines several key topics, such as the utilization of biofuels as a sustainable renewable resource, recycling and untapped waste-to-energy products, and other carbon-neutral strategies in various industries, such as the transportation, construction, and manufacturing sectors. It provides recent updates on the latest technologies, modeling, design, and technical aspects, as well as several practical case studies. The current world energy scenario is examined and various solutions to larger environmental problems are outlined in terms of the shift to more alternative energy sources. Features: Minimizes technical jargon in a straightforward style for a wider audience Discusses sustainable options for different industries, such as the use of green materials in the construction sector, biofuels for transportation, and many more Includes numerous illustrations, tables, and figures to aid in understanding This book serves as a practical reference for engineers, researchers, environmental consultants working in renewable energy industries, and students.

The New Frontiers in African Business and Society series provides innovative reflections on the nature of business and society across parts of Africa and its emerging economy. Distinguished scholars formulate important answers to the problems within the continent, discovering new avenues of research and pathways forward.

The book Solvents - Dilute, Dissolve, and Disperse - Insights on Green Solvents and Distillation takes the reader on a journey of chemistry and engineering toward sustainability. The book unravels the potential of green solvents, which are remarkably versatile, low-toxicity alternatives to traditional solvents that promise to reduce environmental impact. Latest research on supercritical fluids, ionic liquids, and deep eutectic solvents are carefully reviewed with emphasis on the numerous applications of green solvents. Additionally, as industrial demands evolve, the development of existing techniques is necessary. Distillation, the cornerstone of industrial separation, has been reimagined through groundbreaking approaches allowing for reduced operational costs and a diminished environmental footprint. The novel approaches in distillation offer advancement, allowing us to tackle the complexities of separating complex mixtures with unprecedented precision. Acknowledging these facts, this book covers new trends in this exciting research field of science and engineering. The book is an essential read for chemists, engineers, environmentalists, and anyone committed to fostering innovation for a greener tomorrow.

Presenting ten exciting chapters delving into the socio-cultural aspects of African contexts and their profound impact on regional, national, and international business, Contextualising African Studies lays the foundation for a comprehensive exploration of Africa's business landscape.

This book explores the key players, challenges and policies affecting higher education in Africa. It also explores the marketing strategies and the students’ selection process, providing theoretical and practical insights into education marketing in Africa. In particular, it focuses on the competition for students. The growing number of student enrolments, the public sector’s inability to meet the ever-increasing demands and new private universities springing up mean that it is essential for universities to identify their market and effectively communicate their messages. Although there has been substantial theoretical research to help shed light on students’ choices and universities' marketing strategies, little work has been undertaken on higher education in the African context. Filling that gap in the research, while at the same time acknowledging the regional differences in Africa, this book offers empirical insights into the higher education market across the continent.
