Community psychology is an applied branch of psychology that places emphasis on understanding people in their own context, and promoting their health and wellbeing within this context. It is particularly relevant in the quest to empower people to address psychosocial problems through community development. Community psychology focuses on how theories and research are used to inform practice in South Africa.

Community psychology applies theories relevant to the study of people in South Africa’s diverse multicultural environment, delving deeper into the psychosocial problems of violence and crime, poverty and unemployment, racism and xenophobia, gender-based violence/gender equity, masculinities, community trauma, HIV/AIDS, substance abuse, child and adolescent mental health and the elderly in the community.

It develops a new perspective on interpretation of communities, resulting in meaningful engagement which can lead to real social change.

"The best-kept secret in corporate life is the vanishing act of women on their way to the top. Despite massive attention to the issue the number of women in top positions remains shockingly low. This book shows what women themselves can do to optimize their careers and how this can bring benefits to the companies and organizations they work for"--

Several cyanobacterial species can produce powerful toxins that provide a serious threat for water quality, other aquatic organisms, and human health. These harmful cyanobacteria are especially prominent in freshwater ecosystems, and are a major concern for water managers.The purpose of this work is to provide an up-to-date overview of the advances in our knowledge of harmful cyanobacteria. The work is directed towards graduate students and scientists in aquatic microbiology, aquatic ecology, environmental toxicology, and water management, and academic professionals in water management and environmental policy.

Several cyanobacterial species can produce powerful toxins that provide a serious threat for water quality, other aquatic organisms, and human health. These harmful cyanobacteria are especially prominent in freshwater ecosystems, and are a major concern for water managers.

From a scientific perspective, there are many recent advances in this research area:
- Owing to the scientific revolution in genomics, new molecular techniques have been developed that enable the detection of toxic cyanobacteria at a very early stage.
- New laboratory culture techniques have enabled eco-physiological studies of toxin production at a detailed scale that was beyond reach until recently.
- Remote sensing of freshwater cyanobacteria is a rapidly expanding field, owing to the increased spectral resolution of airborne data.
- New computational techniques have led to advanced models on the population dynamics of cyanobacteria.

From a management perspective, recognition of the toxins produced by harmful cyanobacteria has recently led to new environmental policies with respect to toxic cyanobacteria in many western countries.

The purpose of this work is to provide an up-to-date overview of the advances in our knowledge of harmful cyanobacteria. The work is directed towards graduate students and scientists in aquatic microbiology, aquatic ecology, environmental toxicology, and water management, and academic professionals in water management and environmental policy.

"This is an outstanding volume that should be a 'must-see' reference for all scientists and environmental professionals who are interested in cyanobacterial ecology and water quality management." Val H. Smith, University of Kansas, USA

Dementia is a brain disorder that seriously affects a person's ability to carry out daily activities. The most common form of dementia among older people is Alzheimer's disease (AD), which involves the parts of the brain that control thought, memory, and language. Age is the most important known risk factor for AD. The number of people with the disease doubles every 5 years beyond age 65. AD is a slow disease, starting with mild memory problems and ending with severe brain damage. The course the disease takes and how fast changes occur vary from person to person. On average, AD patients live from 8 to 10 years after they are diagnosed, though the disease can last for as many as 20 years. Current research is aimed at understanding why AD occurs and who is at greatest risk of developing it, improving the accuracy of diagnosis and the ability to identify those at risk, discovering, developing, and testing new treatments, and discovering treatments for behavioural problems in patients with AD. This book gathers new and important state-of-the-art research from leading scientists throughout the world which offers important information on understanding the underlying causes and discovering the most effective treatments for Alzheimer's Disease
