The Response Of Lianas To 20 Yr Of Nutrient Addition In A Panamanian Forest, Stefan A. Schnitzer, Sergio Estrada Villegas, S. Joseph Wright

Biological Sciences Faculty Research and Publications

Over the past two decades, liana density and basal area have been increasing in many tropical forests, which has profound consequences for forest diversity and functioning. One hypothesis to explain increasing lianas is elevated nutrient deposition in tropical forests resulting from fossil fuels, agricultural fertilizer, and biomass burning. We tested this hypothesis by surveying all lianas ≥1 cm in diameter (n = 3,967) in 32 plots in a fully factorial nitrogen (N), phosphorus (P), and potassium (K) addition experiment in a mature tropical forest in central Panama. We conducted the nutrient-addition experiment from 1998 until present and we first …

Inferior St-Elevation Myocardial Infarction Presenting When Urgent Primary Percutaneous Coronary Intervention Is Unavailable: Should We Adhere To Current Guidelines?, Yochai Birnbaum, Glenn N Levine, John French, Juan Carlos Kaski, Dan Atar, Mahboob Alam, David Hasdai, Hani Jneid, Barry F Uretsky

Faculty, Staff and Students Publications

The pivotal studies that led to the recommendations for emergent reperfusion therapy for ST-elevation myocardial infarction (STEMI) were conducted for the most part over 25 years ago. At that time, contemporary standard treatments including aspirin, statin, and even anticoagulation were not commonly used. The 2013 American College of Cardiology Foundation (ACCF)/American Heart Association (AHA) guidelines and the 2017 European Society of Cardiology guidelines give a class I recommendation (with the level of evidence A) for primary percutaneous coronary intervention (pPCI) in patients with STEMI and ischemic symptoms of less than 12 h. However, if the patient presents to a hospital …

LSU New Orleans Theses and Dissertations

A play in two acts, Purchased tells the story of Francois DeLord and his journey from being a French Creole of New Orleans to becoming a Black man in America. In 1803, Napoleon sold France’s North American holdings to the United States in what became known as the Louisiana Purchase. Americans flooded into the city, bringing with them boatloads of money and a social philosophy that clashed with long-held local traditions. The sale doubled the size of the young nation, and ignited a culture war in New Orleans,

Phishprint: A Novel Framework For Scalable Evaluation Of Web Security Crawlers And Mining Of Unknown Cloaking Vectors, Bhupendra Acharya

LSU New Orleans Theses and Dissertations

We built a novel scalable, low-cost, and generic platform named PhishPrint to enable the evaluation of Web Security Crawlers (WSCs) against previously unknown cloaking weaknesses. PhishPrint completely avoids the use of any simulated phishing sites and blocklisting measurements. We used PhishPrint to evaluate an unprecedented number of WSCs (23) including highly ubiquitous services such as Google Safe Browsing and Microsoft Outlook e-mail scanners. Our 70-day study found several unknown cloaking weaknesses with which we constructed 5 effective cloaking attack vectors (including 4 novel ones). In particular, it was shown that the entire WSC ecosystem is extremely vulnerable to a novel …

Design And Synthesis Of Novel No-Drug Hybrid Compound And Green Catalytic Activity Evaluation Of Synthesized Silver Nanoparticles-Halloysite Nanocomposite, Majed Abdullah Bajaber

LSU New Orleans Theses and Dissertations

Acetaminophen is a well-known analgesic that can manage pain and reduce fever. SCP-1 is a derivative of acetaminophen that showed significantly reduced hepatotoxicity and nephrotoxicity comparative to acetaminophen. Nitric oxides have been well known to play a key role in a wide variety of physiological and pathophysiological important processes. It was therefore of interest to synthesize a nitric oxide donor linked to SCP-1 that could have enhanced analgesic and antipyretic activity. A furoxan CAS 1609 as NO-donor was synthesized and linked to SCP-1 successfully. The furoxan CAS 1609 was initially synthesized from tetronic acid to give 1,2- dioxime in 86 …

Existing Data Sources As Tools For Entry-Stage Extension Professionals, Olivia Caillouet, Matt Benge, Amy Harder

Journal of Extension

Due to the nature of Extension, work across counties differs because efforts are grounded in the needs of a community and intentional programming helps address these needs. A common competency required for entry-stage Extension professionals is program development, which includes planning, design, implementation, and evaluation. Understanding a community's needs is a crucial aspect of the program planning process, yet new Extension professionals may not know where to locate existing information about their communities. Before creating Extension programs, Extension professionals should understand local communities and identify existing data to facilitate the needs assessment phase of program development.

Extension personnel can use the list generated to assess perceptions of importance and ability level regarding IPM …

Comparing Linkages Between Descriptive Norms And Current And Intended Outdoor Water Conservation, Laura A. Warner, Savanna Turner, Lisa Lundy

Journal of Extension

The study presented here was used for evaluating how theory of planned behavior variables (attitude, perceived behavioral control, subjective norms) and perceptions of others' outdoor water conservation (descriptive norms) related to individuals' own conservation and intent to conserve. The theory of planned behavior predicted current and intended conservation similarly. Descriptive norms from close-peer and state referent groups improved predictions of current practices but not behavioral intentions. Descriptive norms may be more influential when Extension clients are establishing routines pertaining to outdoor water conservation (e.g., installing a new landscape). Extension professionals should strategically communicate a conservation norm at similar opportune times.

Social Media Use For Farmers Market Communications In Illinois, Dandan Tao, Taylor Kathryne Ruth, Janie Maxwell, Hao Feng

Journal of Extension

Social media has been recognized as a powerful tool supporting communication of many topics in the agriculture industry. We explored the use of social media platforms among farmers market managers and specialty crop growers in Illinois through an online survey. Facebook, Instagram, and Twitter were platforms used by the majority of respondents. We found that social media was used primarily for communicating with consumers for marketing purposes. We identified major training needs of farmers market stakeholders related to using social media to promote business and convey food safety information.

Ten Steps For Establishing A Succession Plan Addressing Volunteer Disengagement, Laura Brumbaugh Robertson

Journal of Extension

What happens when volunteers disengage from an Extension program? What steps should Extension professionals take to fill a vacated role? There is a robust amount of research regarding best retention practices once volunteers are plugged into a program. However, there is a gap in current volunteer literature regarding practical applications to prepare existing volunteers to take on new roles. Incorporating proven strategies through practical applications would allow Extension professionals to address volunteer disengagement before it happens. Extension professionals can consider 10 steps to develop a succession plan to address volunteer disengagement.

Otolith Age Validation And Microchemical Investigation Of The Northern Stock F Atlantic Black Sea Bass (Centropristis Striata), Elise R. Koob

Graduate Masters Theses

Black sea bass (Centropristis striata) is a demersal marine species that supports extensive commercial and recreational fisheries along the Atlantic coast. A recent expansion into the Gulf of Maine raises questions about this species’ movement and population dynamics in the region. Additionally, the 2016 catch-at-age stock assessment model for the northern stock incorporated a population split at the Hudson Canyon. Though this model better accounts for differences in populations, several issues remain. First, validation of the otolith ageing technique for this stock is incomplete; and, second, the origin of fish that moved into the northern ranges of the Gulf of …
