Flood pulsing and metacommunity dynamics in a desert riparian ecosystem
No full textQuestions: 1) Does flood pulsing drive metacommunity dynamics in desert southwestern riparian ecosystems? 2) Do species along a specialist to generalist gradient respond to spatial and/or temporal metacommunity dynamics preferentially?
Location: Desert southwestern USA.
Methods: We sampled vegetation and propagule banks in four communities located along a hydrogradient in a spatially structured riparian ecosystem. Plant species were classified into a combination of wetland indicator score and Grime's life-history classes, and also into specialist, moderate, and generalist categories. ANOVA was used to test differences between data categories amongst communities (both extant vegetation and propagule banks) and between data categories by soil depth. Sorenson's similarity coefficient was calculated to determine the degree of similarity in communities of specialists and generalists between extant vegetation and propagule banks.
Results: Wetland species were found in soils from active channel bar to the outer extent of the floodplain, indicating broad dispersal by flood waters. Specialists, such as wetland ruderals, were found within all soil depths. Specialist communities in propagule banks had little similarity with specialist communities in extant vegetation. Generalists, particularly upland ruderals, were restricted to surface soil layers. Communities of generalists in propagule banks were similar to extant communities of generalists. Collectively, these patterns indicate that specialists and generalists are responding to temporal and spatial dynamics respectively.
Conclusions: Flood pulsing is one mechanism that drives metacommunity dynamics in highly dynamic desert southwestern riparian ecosystems. Propagule banks enable many herbaceous species to respond to multidimensional metacommunity dynamics by acting as a storage mechanism that can buffer populations in fluctuating environments
Diversity in Health Care: A Case of Diversity in Long-Term Care
No full textAchieving diversity is a necessity in any organization but is especially important in long-term care. The care delivered is to a diverse group of patients and their families. Therefore, this case allows the analysis of diversity in one long-term care company. While Federal EEO requirements include a report of diversity annually for employers and contractors, this is a further analysis of the diversity data used for reporting. Looking into frequency and distributive statistics allows a better understanding of the diversity of this company
Improving Student Learning in an Operations Management Course: An Integrated Group Project
No full textThis article describes a problem-based learning (PBL) approach to teaching core operations management concepts during an undergraduate course. The approach employs a semester-long, open-ended challenge in which each small student group creates a fictional company operating in an industry where there are real large-scale transnational companies, and develops a competitive profile for the company with respect to ten elements of a commonly-taught operations management framework. The results of the PBL-based project are compared to a baseline teaching method of lecture, practice problems, and examinations, and to a simplified case study in which students choose an existing large transnational company and research the company’s existing profile throughout the term or semester concerning the ten operations-management decisioning concepts

An Oral Health Survey Instrument to Assist the Bariatric Nurse in the Early Determination of Suitable Surgery Candidacy
No full textWith the seemingly unending upward spiraling of healthcare costs, healthcare practitioners need to develop approaches to afford their patients the best possible outcomes for the lowest possible costs. This paper presents the linkages between oral disease and systemic disease and then gives bariatric nurses easily implemented and cost effective strategies using oral disease indicators to affect better surgery outcomes

Fitz-Gibbon, Andrew, ed. Positive Peace: Reflections on Peace Education, Nonviolence, and Social Change. Rodopi: Amsterdam. 2010. Print.
This collection of essays displays varied views on what peace means and how one may achieve it, with several different practical tactics and anecdotes throughout. In the Editorial Forward, William C. Gay sets up basic vocabulary for the text, noting, “negative peace is defined as the mere absence of war, while positive peace is defined as also entailing the presence of justice […] The ultimate goal is to achieve social justice” (xv). In this framework, a peaceful society, in addition to not being at war, is one in which society is balanced and without violence, including complex structural systems of violence.
