Ecological systems theory is explicated as a current form of successive systems models used in social work. Behavior principles assumptive in this model are identified: of exchange balance, inner consistency, and dialectial change. Several misconceptions of ecological systems theory and a cultist aspect of its current popularity are addressed. Advantages, including the emergence of practice pri...

Research on both the forms and functions of aggression has yet to include the experiences of lowincome minority adolescent girls, particularly Latinas. The present study addresses this limitation by applying ecological systems theory to identify risk and protective factors across multiple domains that increase and mitigate aggressive behavior among a sample of 212 low-income minority adolescent...

In the context of the study reported in this paper, of transition from nonformal primary schools to formal secondary schools in Bangladesh, the difficulties of smooth school transition relate not only to the making of new relationships and adaptation to new norms in a new environment, but to a very different approach to educating disadvantaged people. The role of images is explored as part of a...

Bronfenbrenner’s ecological systems theory (EST) is among the most widely adopted theoretical frameworks for studying individuals in ecological contexts. In its traditional formulation, different levels of ecological systems are viewed as nested within one another. In this article, we use Simmel’s notion of intersecting social circles and Bronfenbrenner’s earlier writing on social networks to d...

This book consists of 14 chapters covering important aspects in regards to various terrestrial ecosystems, wetlands, river systems, mine site rehabilitation, marsh ecology and heavy metals pollution. Also aims to fill some of the information gaps in ecological restoration, particularly in under-researched ecosystems around the world. Restoration ecology emerged as a separate field in ecology in...

This chapter explores the development of a new type of scientific tool – manmade closed ecological systems. These systems have had a number of applications within the past 50 years. They are unique tools for investigating fundamental processes and interactions of ecosystems. They also hold the potentiality for creating life support systems for space exploration and habitation outside of Earth’s...

Ecology has been eminently a descriptive science despite some pio­ neering work by theoreticians such as Lotka, Volterra, Nicholson, and others. Description is a first step toward understanding a system. How­ ever, such a first step needs to be accompanied by the development of a theoretical framework in order to achieve real insight and, whenever possible, predictive power. Ecologists are incr...
