Ecological Resilience Indicators For Salt Marsh Ecosystems, Scott T. Allen, Camille L. Stagg, Jorge Brenner, Kathleen L. Goodin, Don Faber-Langendoen, Christopher A. Gabler, Katherine Wirt Ames

School of Earth, Environmental, & Marine Sciences Faculty Publications

Salt marshes are coastal ecosystems within the intertidal zone, characterized by hypoxic, saline, soil conditions and low biodiversity. Low diversity arises from frequent disturbance and stressful conditions (i.e., high salinity and hypoxia), where vegetative reproduction and low competition result in mostly monotypic stands, with some differences in plant community influenced by flooding regime (described below). While there are several types of salt marshes in the Northern Gulf of Mexico (NGoM), ranging from low to high salt marshes and salt flats (Tiner, 2013), Spartina alterniflora–dominated salt marshes in the Coastal and Marine Ecological Classification Standard (CMECS) Low and Intermediate Salt Marsh …

The Effectiveness Of Screening For Comorbid Depression Among Outpatients With Chronic Diseases In Maryland, Linda Hasssan Allibalogun Jan 2018

The Effectiveness Of Screening For Comorbid Depression Among Outpatients With Chronic Diseases In Maryland, Linda Hasssan Allibalogun

Walden Dissertations and Doctoral Studies

Depression is a pervasive mental health disorder worldwide. Although being diagnosed with chronic illness exacerbates susceptibility to depression, detection and subsequent treatment of comorbid depression in primary care settings remain suboptimal because patients with chronic medical disorders are not commonly screened for depression. There is a need to initiate proactive measures by implementing routine screening in primary care settings. The plan-do-study-act (PDSA) model guided an intervention to establish a depression screening practice. This study aimed to determine if the implementation of evidence-based screening for depression using the Patient Health Questionnaire-9 (PHQ-9) tool could increase diagnosis of comorbid depression among patients …

An Examination Of Mississippi Teachers' Likelihood To Report Child Sexual Abuse And The Potential Effect On The Rates Of Victim Disclosure, Marjorie M. Cox Jan 2018

An Examination Of Mississippi Teachers' Likelihood To Report Child Sexual Abuse And The Potential Effect On The Rates Of Victim Disclosure, Marjorie M. Cox

Honors Theses

Within the last year alone, hundreds of news reports have swept the United States about the experiences of sexually abused children, shocking citizens with chilling accounts from both perpetrators and victims. Once their initial reaction plays out, many people resume their daily lives with little thought to the details or repercussions of the abuse; after all, incidents of that nature only befall other peoples' children. How does this secondary response affect child victims? Are children more or less likely to divulge their abuse with a societal response such as this? These are questions that the researcher sought to answer within …
