Unifying Psychology And Experiential Education: Toward An Integrated Understanding Of Why It Works, Susan Houge Mackenzie, Julie S. Son, Steve Hollenshorst

Recreation, Parks and Tourism Administration

This article examines the significance of psychology to experiential education (EE) and critiques EE models that have developed in isolation from larger psychological theories and developments. Following a review of literature and current issues, select areas of psychology are explored with reference to experiential learning processes. The state of knowledge and emerging paradigms in positive psychology, self-determination theory, flow theory, and neuropsychology are explored in an effort to better understand the mechanisms underpinning experiential learning and program development. Implications for practitioners and future research directions are discussed in relation to these emerging bodies of knowledge.

Effects Of Covering System, Sealing Time, And Packing On Fermentation, Nutritional Quality, And Organic Matter Loss Of Corn Silage In A Drive-Over Pile, Katie Rose Nutcher

Dairy Science

This project involved an experiment conducted using a 550-ton capacity drive-over pile of whole-plant corn silage. The main effects compared were: packing the final forage surface with a loader or crawler, delay or immediate sealing, and covering with standard plastic or an oxygen barrier film.

Numerous studies have shown that the absence of oxygen in silage stored in a bunker silo or pile is crucial for proper fermentation and to ensure the highest quality silage at feed out. When oxygen is allowed to permeate through the covering material, it leads to visible spoilage. This trial showed that the oxygen barrier …

Beyond Social Exchange Theory: An Integrative Look At Transcendent Mental Models For Engagement, Latha Poonamallee, Sonia Goltz

College of Business Publications

In this paper, we develop an integrative conceptual framework capturing the underlying mental models that guide engagement in relationships at work and elsewhere. Specifically, we are looking at mental models that go beyond egocentrism and social exchange, which have served as the basis for most frameworks found in research on organizations. The goal of this paper is to present a more complex picture of human cognition and behavior that suggests that egocentrism is not an exclusive motivator. We view this more integrative framework as a set of concentric circles of increasingly inclusive and expansive identities. Although the mental models used …

Resolution Of Central Nervous System Astrocytic And Endothelial Sources Of Ccl2 Gene Expression During Evolving Neuroinflammation, Bandana Shrestha, Shujun Ge, Joel S. Pachter

UCHC Articles - Research

Background

The chemokine CCL2 is a critical mediator of neuroinflammation in diseases such as multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). CCL2 drives mononuclear cell infiltration into the central nervous system (CNS), alters expression and distribution of microvascular endothelial tight junction proteins, and disrupts the blood–brain and blood-spinal cord barriers. Immunohistochemistry has consistently revealed astrocytes to be a source of this chemokine during neuroinflammation, while providing less uniform evidence that CNS endothelial cells may also express CCL2. Moreover, the relative contributions of these cell types to the CNS pool of CCL2 during MS/EAE are unclear and …
