Aphid Amino Acid Transporter Regulates Glutamine Supply To Intracellular Bacterial Symbionts, Daniel R.G. Price, Honglin Feng, James D. Baker, Selvan Bavan, Charles W. Luetje, Alex C.C. Wilson

Faculty Publications

Endosymbiotic associations have played a major role in evolution. However, the molecular basis for the biochemical interdependence of these associations remains poorly understood. The aphid-Buchnera endosymbiosis provides a powerful system to elucidate how these symbioses are regulated. In aphids, the supply of essential amino acids depends on an ancient nutritional symbiotic association with the gamma-proteobacterium Buchnera aphidicola. Buchnera cells are densely packed in specialized aphid bacteriocyte cells. Here we confirm that five putative amino acid transporters are highly expressed and/or highly enriched in Acyrthosiphon pisum bacteriocyte tissues. When expressed in Xenopus laevis oocytes, two bacteriocyte amino acid transporters displayed significant …

Changing Microspatial Patterns Of Sulfate-Reducing Microorganisms (Srm) During Cycling Of Marine Stromatolite Mats, Alexandru I. Petrisor, Sandra Szyjka, Tomohiro Kawaguchi, Pieter T. Visscher, Robert Sean Norman, Alan W. Decho

Faculty Publications

Microspatial arrangements of sulfate-reducing microorganisms (SRM) in surface microbial mats (~1.5 mm) forming open marine stromatolites were investigated. Previous research revealed three different mat types associated with these stromatolites, each with a unique petrographic signature. Here we focused on comparing “non-lithifying” (Type-1) and “lithifying” (Type-2) mats. Our results revealed three major trends: (1) Molecular typing using the dsrA probe revealed a shift in the SRM community composition between Type-1 and Type-2 mats. Fluorescence in-situ hybridization (FISH) coupled to confocal scanning-laser microscopy (CSLM)-based image analyses, and ³⁵SO₄²⁻-silver foil patterns showed that SRM were present in surfaces of …

A Field Guide To Genomics Research, Andrea H. Bild, Jeffrey T. Chang, W. Evan Johnson, Stephen R. Piccolo

Faculty Publications

High-throughput technologies are enabling scientists to profile genomes, transcriptomes, proteomes, and metabolomes at an unprecedented scale [1]. All this “-omics” research (let's call it genomics for simplicity) is exciting—and game changing—but it's also fraught with dangers for the tenderfoot. Here, we've put together a brief “field guide” for those wishing to visit the genomics frontier, in which we use caricatures to illustrate various pitfalls that can beset those who inhabit this new territory. By documenting the behaviors of these common types, we hope to guide researchers in their quest to apply sound practices when designing genomics experiments and analyzing …

Assessing Biogeochemical Effects And Best Management Practice For A Wheat–Maize Cropping System Using The Dndc Model, Feng Cui, Xunhua Zheng, Chunyan Liu, K. Wang, Zaixing Zhou, Jia Deng

Faculty Publications

Contemporary agriculture is shifting from a single-goal to a multi-goal strategy, which in turn requires choosing best management practice (BMP) based on an assessment of the biogeochemical effects of management alternatives. The bottleneck is the capacity of predicting the simultaneous effects of different management practice scenarios on multiple goals and choosing BMP among scenarios. The denitrification–decomposition (DNDC) model may provide an opportunity to solve this problem. We validated the DNDC model (version 95) using the observations of soil moisture and temperature, crop yields, aboveground biomass and fluxes of net ecosystem exchange of carbon dioxide, methane, nitrous oxide (N2O), nitric oxide …

Measurement Issues With Couple-And Family-Level Data, Dean M. Busby, Franklin O. Poulsen

Faculty Publications

Early in my (D.B.) training as a family therapist, I did some co-therapy with a clinical psychology student who wanted to learn how to work with couples. The couple we were working with was quite volatile, and it was not uncommon for the dialogue between the spouses to get heated. While it was challenging enough to keep the interactions between the partners moving in a productive direction, my co-therapist was quite uncomfortable with conflict and would emotionally "check out" of the session as soon as things became intense. Each time a session was challenging and conflict became intense, my co-therapist …

Enhancing Leadership Skills In Clinical Practicum: A Medical Surgical Nursing Class Experience, Gisela Schmidt

Faculty Publications

The healthcare system in the United States of America (USA) with its complex environment and fast-paced changes requires well-prepared professional nurses; with outstanding leadership skills to address the demanding challenge. Nursing schools need to prepare students for that role. To fulfill this commitment, a Medical Surgical II course from a Baccalaureate Nursing Program incorporated into its clinical experience the student team leader role. Leadership skills need to be learned. Instructors cannot expect nursing students to surge through leadership theory, graduate, be exposed to real world situations; and then simply assume leadership positions without hands-on exposure. Preparing nursing students during their …

Unintended Consequences: Reverberations Of Special Immigrant Juvenile Status, Lauren Heidbrink

Faculty Publications

This paper details the socio-legal factors that shape the relationship between the child, the family, and the state, and the ways unaccompanied migrant children’s lives have come to be defined and contested. The legal identity of migrant children is socially situated within a history that intertwines social movements of helping professionals, legal jurisdictions characterized by increasingly intolerant approaches to juveniles, and shifts in the treatment of unauthorized migrant youth under immigration law over time. In a globalized world, this triangular relationship between children, families, and the state becomes increasingly complex and dynamic. Social policies and legal norms often lag far …

Cash Holdings Of S&P Firms Over The Past Decade, Mary Fischer, Treba Marsh, Todd A. Brown

Faculty Publications

Over the past decade, financial research suggests US firms hold a significant amount of cash. This growing amount of cash has attracted attention from economists, the business press and government. A firm’s cash balance could well indicate the firm elects to hold cash rather than invest in suboptimal investments. There are trade-offs between holding too much cash and holding too little. This exploratory study attempts to find financial relationships that explain the cash held by S&P 100 firms over the decade from fiscal year 2002 to 2011.

Thinking Through The Photographic Encounter: Engaging With The Camera As Nomadic Weapon, Cala Coats

Faculty Publications

This paper considers the photographic act as an affective and affirmative encounter--a reflexive, embodied, and relational community engagement that may produce a rupture in our habitual modes of thinking. The author uses the Deleuzo-Guattarian concept of the nomadic weapon to consider how the camera may become an affective trigger for self-reflexivity, catalyzing the potential of nomadic thinking in a participatory frame. By transposing uses of photography as visual research method across cultural geography, visual anthropology, sociology, and arts-based educational research, the author discusses shifts in the function of photography from a practice emphasizing image production to an embodied and performative …

Instream Woody Debris And Riparian Forest Characteristics In The Sabine River, Texas, Matthew W. Mcbroom, Michael Ringer, Yanli Zhang

Faculty Publications

We examined instream large woody debris (LWD) dynamics on the Sabine River, TX. All wood >10 cm in diameter and >2 m long was measured on four river meanders (meander wavelengths) below the dam on Toledo Bend Reservoir. We determined LWD species, degree of decay, bank orientation, jam association, and stage contact. We also measured riparian vegetation characteristics on each meander. LWD volumes were significantly greater at the site immediately below Toledo Bend Dam, due to the relatively steeper channel gradient and higher rates of channel erosion. Based on mass balance estimates, between 11 and 21% of total annual recruitment …

Is The Community Health Needs Assessment Replacing The Certificate Of Need?, Pamela C. Smith, Kelly Noe

Faculty Publications

The purpose of this paper is to question the need for Certificates of Need at the state level. At the Federal level the Affordable Care Act requires hospitals must justify their community impact through a Community Health Needs Assessment (IRS Form 990 Schedule H) in order to retain their tax-exempt status. Not-for-profit hospitals will save money, time and personnel resources if the CON is combined with the CHNA and all states accept this change, no longer requiring the CON.

Applying The Social Ecological Model To Violence Against Women With Disabilities, Miranda Sue Terry

Faculty Publications

Violence against women (VAW) is a broad term used to capture aggressive acts committed toward women, which consists of numerous types of violence with the most commonly known types of abuse being emotional, sexual, and physical. One relatively invisible group, women with disabilities, not only experiences emotional, sexual, and physical abuse but also a unique type of disability-related abuse, which may increase their risk of experiencing acts of violence. The U.S. Congress passed two distinct yet not mutually exclusive policies into law to address violence against women and rights for individuals with disabilities: the Violence against Women Act and the …

Anatomy Of The Reasonable Observer, B. Jessie Hill

Faculty Publications

The “reasonable observer” heuristic — the fictional person from whose perspective we are to judge whether a governmental symbol or display or practice violates the Establishment Clause — has been under fire for decades. Primarily, critics argue that the reasonable observer, as conceived by the Supreme Court, is incapable of representing a community perspective because he does not sufficiently resemble a real, breathing, flesh-and-blood person. This criticism can be further articulated as two specific complaints: first, that too much knowledge is imputed to the reasonable observer, making him more omniscient than the average passerby; and second, that the reasonable observer, …

Text 4 Health: Addressing Consumer Health Information Needs Via Text Reference Service, Van M. Ta Park

Faculty Publications

This study seeks to provide empirical evidence about how health-related questions are answered in text reference service in order to further the understanding of how to best use texting as a reference service venue to fulfill people’s health information needs. Two hundred health reference transactions from My Info Quest, the first nation-wide collaborative text reference service, were analyzed identify the types of questions, length of transactions, question-answering behavior, and information sources used in the transactions. Findings indicate that texting-based health reference transactions are usually brief, and cover a wide variety of topics. The most popular questions are those seeking general …

Strategies Employed By Inner-City Activists To Reduce Alcohol-Related Problems And Advance Social Justice, Laurie Drabble, Denise Herd

Faculty Publications

This study explored strategies employed by activists engaged in efforts to change policies and laws related to selling and promoting alcoholic beverages based on in-depth interviews with 184 social activists in seven U.S. major cities. Nine strategies aimed at improving local conditions and influencing policy were described by activists across regional contexts. Grassroots mobilization was central to all other strategies, which included the creation or enforcement of laws, meeting with elected officials, media advocacy, working with police/law enforcement, education and training, direct action, changing community norms, and negotiating with store owners.

Strengthening Services For Lgbtq Clients: Best Practice Recommendations For Rural Low-Income Service Providers, Elizabeth Holman, Ramona Oswald, Dina Izenstark, Shawn Mendez, Kimberly Greder

Faculty Publications

People who identify as lesbian, gay, bisexual, or queer (LGBTQ), are more likely to be poor than heterosexualpeople. While they face the same general risk factors for poverty as others, LGBTQ people may experienceadditional discrimination in hiring, employment, and compensation, as well as face rejection from friends and family members who potentially could provide financial support in times of need. For LGBTQ people who live outside of large cities, the risk for poverty is even greater7. Thus, it is important that low-income service providers in rural communities provide culturally competent services to sexual minorities and their families.The purpose of this …

A Picture Is Worth A Thousand Words: Chinese College Students’ Self-Presentation On Social Networking Sites, Qinghua Yang, Zongchao Li

Faculty Publications

Social media have provided new means of self-presentation. Because individuals are able to post notes, pictures, and videos, social media users can construct their personal images on social networking sites (SNSs) and build links with their various communities. This study aims to find out how Chinese college students perceive other users' online self-presentations and how they conduct their own self-presentations through posting pictures on SNSs. Using photo-elicitation as the primary methodology, the authors conducted two.focus groups with male and female participants respectively. With grounded theory as the framework, the qualitative data show gender differences in the attitudes towards extreme self-presentation, …

Specifically, this study examines trends in policies enacted by states over time and types of policies enacted across states in the United States, with a focus on whether laws were supportive or punitive toward women. Findings revealed substantial variability in characteristics of policies (19 primarily supportive, 12 primarily punitive, 12 with a mixed approach, and 8 with no policies). Findings underscore the need to examine possible consequences of policies, especially of punitive policies …

A Method For Evaluating Library Liaison Activities In Small Academic Libraries, Jonathan Miller

Faculty Publications

This article presents a practical method for formative, self-reflective assessment of the liaison activities of individual librarians and to evaluate liaison activities in general. Many libraries evaluate their liaison programs, but few evaluate the effectiveness of individual librarians’ efforts within the program.

Librarians of Rollins College redefined and re-branded their liaison program as “Your Librarian.” As part of this effort, the author surveyed the faculty and assessed the program and the effectiveness of individual librarians. The author outlines the liaison responsibilities, the survey instrument, and how the results are analyzed and used in a process of continuous reflective improvement for …

The Prosocial And Aggressive Driving Inventory (Padi): A Self-Report Measure Of Safe And Unsafe Driving Behaviors, Paul B. Harris, John M. Houston, Jose A. Vazquez, Janan A. Smither, Amanda Harms, Jeffrey A. Dahlke, Daniel A. Sachau

Faculty Publications

Surveys of 1217 undergraduate students supported the reliability (inter-item and test-retest) and validity of the Prosocial and Aggressive Driving Inventory (PADI). Principal component analyses on the PADI items yielded two scales: Prosocial Driving (17 items) and Aggressive Driving (12 items). Prosocial Driving was associated with fewer reported traffic accidents and violations, with participants who were older and female, and with lower Boredom Susceptibility and Hostility scores, and higher scores on Agreeableness, Conscientiousness, Openness, and Neuroticism. Aggressive Driving was associated with more frequent traffic violations, with female participants, and with higher scores on Competitiveness, Sensation Seeking, Hostility, and Extraversion, and lower …

The Conflict Of Visions In Nfib V. Sebelius, Jonathan H. Adler

Faculty Publications

In 2010, few anticipated the fate of health care reform would rest with the Supreme Court. Yet National Federation of Independent Business v. Sebelius emerged as a watershed case that could remake the constitutional landscape. NFIB presented a conflict between two constitutional visions of federal power, and the role of the courts in policing such limits – an unconstrained vision, under which limits on federal power are enforced primarily through the political process, and a constrained vision, under which constitutional limits on federal power are enforced by the courts. The contrasting views of the constitutionality of the individual mandate and …
