Theoretical Foundations of Nursing Practice

2023
Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients. Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.

Physiological Foundation of Stress

2025
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands. Role of the Sympathetic Nervous System Adrenaline triggers the...

Social Foundations of Self IV: Self in Digital Communication

2025
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Social Foundations of Self I: Play and Game

2025
The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...

Their effects extend beyond simply offering a place to live. Trees, corals, and kelps can provide shelter, stabilize substrates, alter resource availability, and influence temperature or moisture. These changes create physical conditions that determine which organisms can establish and persist, linking the species’ structural role to community composition and ecosystem functioning.
A species that is abundant or physically dominant can influence habitat across a broad area rather than affecting only isolated locations. Its size, distribution, or abundance may determine how extensively it modifies shelter, substrates, resources, temperature, or moisture. This helps explain why changes in one prominent organism can affect many other members of the community.
Loss can remove the habitat conditions that support biodiversity and regulate interactions among organisms. As shelter, substrate stability, or favorable temperature and moisture conditions decline, community structure and ecosystem functioning may also change. Because these species help maintain ecological conditions, their disappearance can produce broad effects rather than a change limited to one population.
Researchers can examine how a foundation species is associated with habitat formation, community structure, food webs, and ecosystem services. They can also consider how those relationships change after disturbance, during climate change, or following restoration. This broad approach connects physical habitat modification with biological interactions and helps identify consequences that may not be visible from population counts alone.
Restoration efforts can focus on the organisms that create or maintain the physical conditions needed by broader communities. Reestablishing trees, corals, kelps, or other locally important habitat-formers may support shelter, substrate stability, resource availability, and biodiversity. Their role makes them relevant to restoration planning because improving one structural component can influence many associated organisms and ecosystem processes.
This topic connects organismal traits with community-level patterns. Examining how trees shape forests, corals structure reefs, or kelps influence coastal ecosystems helps biologists link habitat formation to food webs, species interactions, ecosystem services, and resilience. It also provides context for understanding how disturbance and climate change can alter biological communities through changes in habitat-forming organisms.
