Uv-C Inactivation Of Microorganisms In Droplets On Food Contact Surfaces Using Uv-C Light-Emitting Diode Devices, Aakash Sharma, Housyn Mahmoud, Brahmaiah Pendyala, Sampathkumar Balamurugan, Ankit Patras

Agricultural and Environmental Sciences Faculty Research

The main objective of this study was to investigate the effectiveness of ultraviolet light (UV-C) emitting diodes for the decontamination of stainless steel food contact surfaces. Listeria monocytogenes (ATCC 19115), Escherichia coli (ATCC 25922), and Salmonella enterica serovar Typhimurium (ATCC 700720) were chosen as challenge microorganisms. Target microorganisms were subjected to UV-C dosages of 0, 2, 4, 6, and 8 mJ cm−2 at an average fluence of 0.163 mW/cm2 using a near-collimated beam operating at 279 nm wavelength. Escherichia coli showed lower sensitivity to UV-C light compared to Salmonella Typhimurium and followed first-order kinetics. Escherichia coli and Salmonella Typhimurium were …

Disrupting Cisheteronormativity In Stem Through Humanism, Meg C. Jones, Desiree Forsythe, Rachel Friedensen, Annemarie Vaccaro, Ryan A. Miller, Ezekiel Kimball, Rachael Forester

Biology, Chemistry, and Environmental Sciences Faculty Books and Book Chapters

Cisheteronormativity is prevalent throughout college STEM discourses and classrooms. In this paper, we present findings from a U.S. based study focused on the experiences of collegiate STEM students with minoritized identities of sexuality and gender (MIoSG) as the backdrop for discussing how current harmful ideologies in STEM perpetuate cisheteronormativity through discursive practice. We propose that humanistic classrooms and pedagogy can work to dismantle cisheteronormative D/discourses in STEM and create MIoSG inclusive STEM classrooms and programs. Our findings highlight the ways participants experienced cisheteronormative D/discourses in their collegiate STEM contexts. We discuss how these experiences might be mitigated through humanistic educational …

Depreciation Changes Ahead, Tina N. Barrett

Cornhusker Economics

When the Tax Cuts and Jobs Act (TCJA) was passed in 2018, a lot of time and focus was placed on all the things that were changing quickly and the things that were 5-6 years out became back burner problems. Amazingly enough, we are now at the stage of the bill where things are starting to phase out. These changes will start to impact tax returns starting in 2023 and will continue increasing taxable income through 2025. The first change is the phase out of the Bonus depreciation. This law has been on the books since 2001 (there was no …

The Synergistic Response Of Primary Production In Grasslands To Combined Nitrogen And Phosphorus Addition Is Caused By Increased Nutrient Uptake And Retention, Eduardo Vázquez, Elizabeth T. Borer, Miguel N. Bugalho, Maria C. Caldeira, Rebecca L. Mcculley, Anita C. Risch, Eric W. Seabloom, George R. Wheeler, Marie Spohn

School of Biological Sciences: Faculty Publications

Background and aims A synergistic response of aboveground plant biomass production to combined nitrogen (N) and phosphorus (P) addition has been observed in many ecosystems, but the underlying mechanisms and their relative importance are not well known. We aimed at evaluating several mechanisms that could potentially cause the synergistic growth response, such as changes in plant biomass allocation, increased N and P uptake by plants, and enhanced ecosystem nutrient retention.

Methods We studied five grasslands located in Europe and the USA that are subjected to an element addition experiment composed of four treatments: control (no element addition), N addition, …

Active Transportation, Context, And Community Participation: Engaged Citizens And Destination-Based Walking And Biking, Jessica Stroope

LSU Doctoral Dissertations

Active transportation is associated with many benefits, including improved health outcomes, higher commuting satisfaction, lower pollution, reduced traffic, and social capital. One understudied area of research on active transportation and social capital is the relationship between active transportation and community participation. Although prior work has established a connection, little is known about the contexts in which this relationship may occur, or about how active transportation may affect the relationship between a context and community participation.

The purpose of Chapter 3 is to examine how active transportation may mediate the relationship between perceptions of place and community participation. Significant work has …

Measuring Food Literacy Among Limited-Resourced Adults, Emelia Clement

LSU Doctoral Dissertations

Food literacy is the interrelated knowledge, skills and behaviors needed to plan and manage, select, prepare, and eat healthy food. It is positively associated with improved consumption of nutritious diets, and can be beneficial to limited-resource adults, who are often at risk for chronic diet-related diseases. Valid instruments for measuring food literacy in this population are scarce but urgently needed. The Eating and Food Literacy Behavior Questionnaire (EFLBQ) can be used to measure food literacy among limited-resource audiences.

Part one of this study aimed to determine the fitness of the EFLBQ to measure food literacy in limited-resource adults. A convenience …

Morphology Of The Ventral Process Of The Sixth Cervical Vertebra In Extinct And Extant Equus: Functional Implications, Sharon May-Davis, Robert Hunter, Richard White

Faculty, Staff and Student Publications

In this study, we examined the ventral process of C6 in extinct and extant Equus (sister taxa to Equus ferus caballus only) with the purpose of describing normal morphology and identifying anomalous variations relevant to recent studies describing a congenital malformation in E. ferus caballus. Overall, 83 specimens from 9 museums and 3 research/educational facilities were examined, totalling 71 extinct specimens from 12 species and 12 extant specimens from 5 species. The lateral view revealed that a large convexity exists in the ventral process between the cranial ventral tubercle (CrVT) and the caudal ventral tubercle (CVT) in the earliest …

Deciphering Tumor Ecosystems At Super Resolution From Spatial Transcriptomics With Tesla, Jian Hu, Kyle Coleman, Daiwei Zhang, Edward B Lee, Humam Kadara, Linghua Wang, Mingyao Li

Faculty, Staff and Student Publications

Cell populations in the tumor microenvironment (TME), including their abundance, composition, and spatial location, are critical determinants of patient response to therapy. Recent advances in spatial transcriptomics (ST) have enabled the comprehensive characterization of gene expression in the TME. However, popular ST platforms, such as Visium, only measure expression in low-resolution spots and have large tissue areas that are not covered by any spots, which limits their usefulness in studying the detailed structure of TME. Here, we present TESLA, a machine learning framework for tissue annotation with pixel-level resolution in ST. TESLA integrates histological information with gene expression to annotate …

Bura Ura, Kendu Waiyo (Rain Falls, Water Rises): The Tyranny Of Water Insecurity And An Agenda For Abolition In Kodi (Sumba Island, Indonesia), Cynthia Twyford Fowler

Faculty Scholarship

This article explores the dynamic links between transformations in freshwater ecosystems and social changes in the Kodi region of Sumba (Indonesia). Insights into the politics surrounding changing hydrosocial systems are generated by using a feminist anthropology approach together with critical development studies and intersectionality theory. In aligning with fellow feminists whose advocacy sometimes takes the form of scholarship, I lay out a five-prong strategy for collecting empirical evidence from persons who are vulnerable when hydrological systems change and offer eight principles for future development interventions. The argument related to the five-prong toolkit is that by conducting intensive, extensive, opportunistic, and …

College Professors As Servant Leaders: Promoting Student Dignity In The Classroom, Garfield R. Benjamin

Journal of Vincentian Social Action

The COVID-19 pandemic brought great disparities to society as a whole. In the education sector, teachers were forced to deliver content while exploring new ways to do so through new or unfamiliar technologies, working in various modalities, while keeping students engaged. This change called for instructors to be flexible, be aware, have empathy, have foresight, build community, communicate, and care for students in this new, mostly virtual, environment. This research explores the idea of college educators as servant leaders by examining definitions of servant leadership, exploring how a servant leader empowers those they lead in times of crisis, examining implications …

Servant Leadership: A Powerful Paradigm For Effective Leadership In Africa, Franklin Ezeorah

Journal of Vincentian Social Action

Lack of good leadership is the greatest undoing of African progress. Unfortunately, good leadership for Africans is not just mirroring the western leadership system but adapting to a style of leadership that is attractive to African people’s way of life and effective for African people’s development and wellbeing. Because leadership is a crucial determining factor for the success of all economic, political, and organizational structures, determining an essential leadership style for a nation-state largely depends on how suitable the style can fit into the complex challenges facing such a nation-state. Considering the viability and profitability of the servant leadership style …

To Protect And To Serve: Community Policing And Servant Leadership Through The Lens Of A Lieutenant Of 25 Years In A Nj Police Precinct, Tara Deworsop

Journal of Vincentian Social Action

Police play a vital role in protecting communities and holding accountable those who have committed violent and property offenses. At the heart of this are the acts of protecting and serving the individuals that make up those communities.

This paper looks at how police officers interact, protect and serve the communities within which they work today. The history of policing and the way police officers are prepared to interact with the public are important. Servant leadership combined with community policing has the potential to create a positive impact that will have a ripple effect.

Using the example of a police …

Servant Leadership And Student-Worker Satisfaction, Shweta Sinha

Journal of Vincentian Social Action

There are several studies that show that the COVID-19 pandemic has led to immense physical and mental health distress. Not only did it impact people’s health but it posed a threat to their financial and professional security. The pandemic, in addition to the several socio-economic challenges, resulted in the restructuring of the corporate work environment. It gave rise to work-from-home culture which eventually became the preferred mode of work for many people. However, companies eventually started calling people back into work reducing the flexibility in schedule that was previously available to employees working from home. As a result, the post-pandemic …

Spirituality Of The Servant Leader, Sally Duffy

Journal of Vincentian Social Action

Reflecting on the words and lived actions of philosophers, theologians and others in the Catholic tradition can inform the Spirituality of a Servant Leader. Thoughtful considerations of the crucified today and personal examination of reader towards systems and structures of oppression should inform those in leadership. Members and alumni of a Vincentian university must recall and embody the leadership styles of Jesus Christ and St. Vincent De Paul in their own places of influence to make for a more just and righteous global society. A Vincentian education calls leaders to holistic care of those they lead coupled with radical principles …

Servant Leadership In Catholic Institutions Of Higher Education, Margaret M. Fitzpatrick

Journal of Vincentian Social Action

Catholic institutions of higher learning are charged with the formation of a significant number of privileged students, who received an advanced degree worldwide. All colleges and universities of Catholic identity, especially its presidents and leadership, would gain to reflect on servant leadership from a Vincentian perspective, What must be done? How must it be done? A Catholic college creates a faith-filled climate where the presence of the Spirit deepens the communion with the entire community, city, state, and beyond. A growing leadership philosophy is based on Greenleaf’s Servant Leadership, where the behaviors and practices emphasize the well-being of those being …

Servant Leadership In The Workplace, Joseph D'Mello

Journal of Vincentian Social Action

Starting from the definition of leadership in general, this work traces servant leadership in particular from its ancient roots to today’s business organizations and argues that the lacuna in organizational servant leadership is likely to be addressed by the growing existential and competitive imperative for organizations to undertake agile transformations.

Centering Those On The Periphery: Mother Teresa As Exemplar Of Catholic Social Thought (Cst) And Social Work Core Commitments To Dignity, Service, And Justice, Anthony Nicotera, Dawn Apgar, Ines Murzaku

Journal of Vincentian Social Action

The literature is void of scholarship on the integration of Catholic Social Thought (CST) and social work. While social work has been historically devoted to helping those who are marginalized and oppressed and recognizes the impact of religion/spirituality on those served, there are almost no articles published that link CST and social work pedagogy and practice. This article identifies why there is a natural fit between CST and social work values. Mother Teresa is presented as an exemplar of CST in action and an inspiration for further integration of CST into social work education. This integration is needed to help …
