Marketing Communications: Key Concepts for Brand Strategy
Anthropomorphism in Brand Communication
Anthropomorphism expands and develops special relationships between consumers and brands by injecting intentions, behaviour, and emotions into specific brands. (Xinyi Jin/Min Quan)
Marketing strategies incorporate anthropomorphic elements into brands and make them or their products perceived in the minds of consumers as living beings.
Levels of Anthropomorphism
- External Level 1: How it looks (age/gender)
- Internal Level 2: What it is like (personality)
- Social Level:
SOA and Cloud Computing: Architecture, Paradigms and Evolution
Service-Oriented Architecture (SOA) as a Technological Driver for Cloud Computing (10 Marks)
Service-Oriented Architecture (SOA) is a software design approach in which applications are built using independent, reusable services that communicate through standard interfaces.
Main Components of SOA:
Service Provider: Creates and offers a service.
Service Consumer: Requests and uses the service.
Service Registry: Stores information about available services.
Service Contract: Defines the interface, rules,

a) Define Computing Paradigms.
Computing paradigms are different models or approaches used to perform computation and process data, such as parallel, distributed, and cloud computing.
b) Differentiate between Grid Computing and Cloud Computing.
Grid computing combines resources from multiple computers to solve large tasks, whereas cloud computing provides on-demand computing services over the internet.
c) List the three Cloud Service Models.
1. IaaS – Infrastructure as a Service
2. PaaS – Platform

Bubble Sort must use an outer loop for passes and an inner loop for adjacent comparisons.
Outer Loop
The outer loop controls the passes. After each pass, the largest remaining unsorted value moves to the end of the current unsorted section.for (int pass = 0; pass < values.length - 1; pass++) {
// one Bubble Sort pass
}
Inner Loop
The inner loop compares adjacent values. The comparison range becomes shorter after every pass because the values at the end are already sorted.for (int i = 0; i &
Sustainability, Ecology and Environmental Ethics: Key Concepts
1.1 Sustainability
Sustainability: possibility that human and other life will flourish on the planet forever (Ehrenfeld). Sustainable development (Brundtland Report, 1987): meeting present needs without compromising future generations’ ability to meet their own needs.
Triple Bottom Line (Elkington, 1997): Planet = ecological; People = social; Prosperity = economic. Nested model: biosphere → society → economy; society and economy depend on nature.
System: connected elements forming a whole. Emergence:
