The introduction explains that economics is the study of how individuals, businesses, and governments make choices when resources are scarce. It presents economics as a way of thinking that helps people understand decisions, markets, and the allocation of limited resources.

The authors introduce the importance of using economic tools and ideas to analyze real-world issues. Economics helps explain why people make certain choices, how markets operate, why prices change, and how government policies can influence economic outcomes.

The introduction explains that macroeconomics is the study of the economy as a whole. It examines large-scale economic issues that affect societies, including overall production, employment, prices, economic growth, and the role of governments and financial institutions in shaping economic outcomes.

The authors introduce the idea that economic decisions made by individuals, businesses, governments, and central banks interact to influence national and global economies. Macroeconomics helps explain questions such as why some countries grow faster than others, why inflation occurs, why unemployment rises and falls, and how economic policies affect people’s lives

1. What is process control?

Process control is the use of measurement, instrumentation, and control systems to monitor and regulate industrial processes automatically.

For example, in a chemical plant, the temperature of a reactor may need to remain at 200°C. A control system measures the actual temperature and adjusts heating or cooling to keep it near the desired value.

2. Why is process control important?

Process control helps industries achieve:

• Safety
• Consistent product quality
• Higher productivity
• Lower operating costs
• Reduced waste
• Efficient use of energy and materials
• Stable operation of equipment

The introduction examines the idea of “promotional culture”—a society in which advertising, public relations, marketing, branding, lobbying, and other forms of promotion have become deeply embedded in everyday life. Davis argues that promotion is no longer limited to selling products; people, organizations, political ideas, celebrities, cultures, and even social movements can all become objects of promotion.

Main ideas

1. Promotion is everywhere
   Modern society is increasingly shaped by promotional activities. Businesses promote products, politicians promote policies and personal images, celebrities promote themselves, and organizations promote their identities.
2. Promotional culture has developed historically
   Davis traces the growth of professional promotional activities such as public relations, advertising, marketing, lobbying, and branding, particularly during the twentieth century.

The introduction explains that psychology is the scientific study of behavior and mental processes. It presents psychology as a discipline that seeks to understand how people think, feel, learn, develop, and interact with others by using scientific methods and evidence-based research.

The authors introduce psychology as a field that connects many areas of human experience, including biology, cognition, emotions, social relationships, personality, mental health, and cultural influences. Psychology helps answer questions about human behavior while challenging common assumptions through careful observation and research.

The introduction explains that the book is a carefully selected collection of UK public law and human rights legislation designed primarily for students. It aims to provide an up-to-date, reliable, and easy-to-use reference for study and examinations. The editor also explains that the statutes have been selected to match the needs of public law and human rights courses and should be used alongside textbooks and case law for a complete understanding of the subject.

The introduction explains that quality management has become a critical factor in organizational success because customers, employees, and stakeholders increasingly expect higher levels of performance and value. The authors introduce Total Quality (TQ) as a comprehensive approach that involves every part of an organization working together to improve quality, productivity, and competitiveness. They emphasize that quality is not only about inspecting finished products but about creating effective processes, preventing problems, involving employees, understanding customer needs, and continuously improving operations. The book presents quality management as an organization-wide philosophy supported by leadership, teamwork, data-based decision-making, and a commitment to excellence. It aims to help students and professionals understand how quality principles can be applied to improve organizational performance in both manufacturing and service environments

The introduction presents quantitative methods as practical tools for using mathematics, statistics, probability and business modelling to understand problems and make better decisions in business, management and finance.

The book is designed to be accessible to students who may have little confidence or previous experience with mathematics. It uses step-by-step explanations, examples, exercises and practical activities.

The introduction explains that resourcing and talent management are among the most important functions of human resource management (HRM). Organizations depend on attracting, selecting, developing, and retaining talented employees to achieve their strategic goals and maintain a competitive advantage.

The introduction emphasizes the following key ideas:

• People are a strategic resource. An organization’s success depends largely on recruiting and retaining employees with the right knowledge, skills, and abilities.
• Resourcing is more than recruitment. It includes workforce planning, employer branding, recruitment, selection, onboarding, retention, succession planning, and managing employee exits.
• Talent management is strategic. Organizations need systematic approaches to identify high-potential employees, develop their capabilities, and prepare future leaders.

The introduction explains that as software systems became larger and more complex, developers needed a common way to model and communicate system designs. The Object Management Group (OMG) developed UML as a standardized modeling language, and it has become the industry standard for object-oriented software development. The book aims to teach UML notation through practical examples and case studies rather than focusing only on theory.
