ItemAssessing Access Services : Building a 5-Year Plan for Sustainable Assessment(Taylor & Francis Online, 2018-07) Hogan, Sean; Hutson, Jeffrey; ; Access ServicesThe University of Baltimore’s Langsdale Library underwent its five-year review in FY2016 (1 July 2015–30 June 2016). A basic, integral and necessary element of this process was the development of an assessment plan. Langsdale Library developed a five-year assessment plan based on the five-year review. The plan aligns the library’s collections and services to the library’s mission and strategic goals as well as linking to the University of Baltimore’s strategic plan, which provides the foundation and direction for the University. At its core, the assessment plan helps to monitor strategic goals; in short, it answers the question, “Are we doing what we say we’re doing?” ItemA conceptual model of systems thinking leadership in community colleges(Systemic Practice and Action Research, 2015-08) Davis, Anne Powel; Dent, Eric B.; Wharff, Deborah M.The pluralistic and often competing goals of myriad constituents, the changing demographics of students, the uncertainty of funding, and the growing demands for accountability from stakeholders have increased the complexity of systems which community college leaders must manage. Emerging from the recent literature on community colleges is a call for new models of leadership in the context of leading in an increasingly uncertain and complex environment. Systems thinking offers a means to help leaders respond to these growing organizational complexities and move leadership from a traditional bureaucratic model to a more adaptive model. A systematic review of literature on systems thinking’s application to organizational performance in higher education was bolstered with evidence from healthcare. Findings revealed three reoccurring ways in which leaders apply systems thinking processes for improving organizational performance. A conceptual model for systems thinking leadership is proposed in which the three processes, characterized as discovery, framing, and action, can be enacted either individually or sequentially for enhancing organizational performance. The model draws upon boundary critique, critical systems thinking, systemic intervention, total systems intervention, systems dynamics, soft systems methodology, complexity theory and complex adaptive systems, yet uses language more readily identifiable to community college practitioners. ItemCongruence between nuclear and mitochondrial DNA: Combination of multiple nuclear introns resolves a well-supported phylogeny of New World orioles (Icterus)(Elsevier Inc., 2010-07) Jacobsen, Frode; Friedman, Nicholas R.; Omland, Kevin E.Darwin’s vision of a “Tree of Life” showing evolutionary relationships among all extant species seems an increasingly feasible goal, at least for vertebrate animals. However, virtually all published molecular phylogenies for closely related animals are based on a single locus – maternally inherited mitochondrial DNA. New approaches using multiple nuclear loci are needed to test published trees and better resolve the twigs of the entire tree of life. Here we use New World orioles (Icterus) to test an approach based on combined analysis of six independent Z chromosome introns. Combined analysis of multiple introns using traditional phylogenetic methods resolved a well-supported species phylogeny of New World orioles. In fact, all major lineages of orioles and several sub-clades that are well-supported by previously published mtDNA data are also strongly supported by the combined nuclear Z-intron tree. The male-biased Z-intron tree presented here is overwhelmingly congruent with the female-exclusive mtDNA tree. A slow rate of mutation relative to mtDNA resulted in generally poorly resolved gene trees when intron loci were analyzed separately. However, strong phylogenetic signal for all but the most recent divergences emerged once multiple loci were concatenated and analyzed in combination. Although there clearly are conditions under which concatenation analysis of nuclear DNA can be misleading, the congruence between mitochondrial and nuclear estimates of the Icterus phylogeny suggests that concatenation remains a powerful tool for inferring phylogenetic relationships for all but very recent divergences. ItemDigital Forensics, A Need for Credentials and Standards(2019-03-31) Zahadat, Nima; School of Criminal Justice; Digital ForensicDespite the phenomenal growth in the digital world and crimes committed using digitaltechniques and tools, there are literally no foundational requirements to perform digitalforensic investigations. While there are several private and mostly for-profit organizationsthat “sell” training and certifications regarding digital forensics credentials, at the federaland state level in the United States, there seem to be nothing of the kind ItemEffects of riparian buffers on nitrate concentrations in watershed discharges: new models and management implications(Ecological Society of America, 2011-07-01) Weller, Donald E.; Baker, Matthew; Jordan, Thomas E.Watershed analyses of nutrient removal in riparian buffers have been limited by the geographic methods used to map buffers and by the statistical models used to test and quantify buffer effects on stream nutrient levels. We combined geographic methods that account for buffer prevalence along flow paths connecting croplands to streams with improved statistical models to test for buffer effects on stream nitrate concentrations from 321 tributary watersheds to the Chesapeake Bay, USA. We developed statistical models that predict stream nitrate concentration from watershed land cover and physiographic province. We used information theoretic methods (AICc) to compare models with and without buffer terms, and we demonstrate that models accounting for riparian buffers better explain stream nitrate concentrations than models using only land cover proportions. We analyzed the buffer model parameters to quantify differences within and among physiographic provinces in the potentials for nitrate loss from croplands and nitrate removal in buffers. On average, buffers in Coastal Plain study watersheds had a higher relative nitrate removal potential (95% of the inputs from cropland) than Piedmont buffers (35% of inputs). Buffers in Appalachian Mountain study watersheds were intermediate (retaining 39% of cropland inputs), but that percentage was uncertain. The absolute potential to reduce nitrate concentration was highest in the Piedmont study watersheds because of higher nitrate inputs from cropland. Model predictions for the study watersheds provided estimates of nitrate removals achieved with the existing cropland and buffer distributions. Compared to expected nitrate concentrations if buffers were removed, current buffers reduced average nitrate concentrations by 0.73 mg N/L (50% of their inputs from cropland) in the Coastal Plain study watersheds, 0.40 mg N/L (11%) in the Piedmont, and 0.08 mg N/L (5%) in the Appalachian Mountains. Restoration to close all buffer gaps downhill from croplands would further reduce nitrate concentrations by 0.66 mg N/L, 0.83 mg N/L, and 0.51 mg N/L, respectively, in the Coastal Plain, Piedmont, and Appalachian Mountain study watersheds. Aggregate nitrate removal by riparian buffers was less than suggested by many studies of field‐to‐stream transects, but buffer nitrate removal is significant, and restoration could achieve substantial additional removal. ItemEmbedding A "Reflexive Mindset: Lessons From Reconfiguring The Internal Auditing Practice(Academy of Management, 2022) Bento, Regina; Soh, Woon Gan; Antonacopoulou, Elena; Rigg, ClareThe education and training of internal auditors is an example of management learning which has received limited attention in management education journals. This paper presents the lessons from an action research inquiry designed to reconfigure the Internal Auditing function to address the problem of a conformance mindset and compliance-based approach. We show how cultivating a ‘reflexive mindset’ becomes a critical catalyst in developing an Internal Auditing approach that leads to the identification of misconduct, conduct risk and deficiencies in the organization’s conduct risk management and governance frameworks. We contribute to advance reflexivity as a practice that can support the reconfiguration of management functions like Internal Auditing, not only by readjusting operating routines but also by encouraging internal auditors to critically (re)consider how their activities may contribute to the common good of the organization’s members and customers. ItemThe ephemerality of secondary forests in southern Costa Rica(Wiley Periodicals, 2018-09-26) Reid, J. Leighton; Fagan, Matthew E.; Lucas, James; Slaughter, Joshua; Zahawi, Rakan A.Secondary forests are increasingly recognized for conserving biodiversity and mitigating global climate change, but these and other desired outcomes can only be achieved after decades of regeneration, and secondary forests are frequently recleared before they recover to predisturbance conditions. We used a time series of aerial photographs (1947‐2014) to evaluate multidecadal persistence of secondary forests across a 320 km² landscape in southern Costa Rica. Secondary forests had relatively short lifespans, with 50% recleared within 20 years and 85% recleared within 54 years of when they were first observed. Larger forest fragments and forests near rivers had a lower reclearance hazard, but forest persistence did not differ over time, indicating that regional forest regeneration may be generally ephemeral. Costa Rica has made an international commitment to restore 1 million ha of degraded land by 2020. Depending on how this is achieved, only half that target may remain forested by 2040. ItemEstimating the Implied Value of the Customer's Waiting Time.(Manufacturing & Service Operations Management,, 2011-12) Chen, Rachel; Lawrences, Robinson; Information System & Decision Science; Information System & Decision ScienceAlmost all research in appointment scheduling has focused on the trade-off between customer waiting times and server idle times. In this paper, we present an observation-based method for estimating the relative cost of the customer waiting time, which is a critical parameter for finding the optimal appointment schedule. ItemExtensiveness of Business Planning and Firm Performance: An Examination into the Drivers of Success and Survival for Startup Firms(University of Twente, 2010) Englis, Paula Danskin; Ratinho, Tiago; Englis, BasilThere is much debate about the role of business planning and new venture creation and success (i.e., Gruber, 2007; Karlsson & Honig, 2007). In this paper, we extend this debate and advance our understanding of the potential role of the extensiveness of business planning. Specifically, we investigate the extensiveness of business planning as it affects firm performance and survival using data from a sample of incubator spin off firms. Extensiveness of business planning is concerned with if the firm has a plan and if it is written down (what Liao & Gartner  refer to as presence and formality), but also the number of sections and the extensiveness each section. ItemExtraction of hydrological proximity measures from DEMs using parallel processing(Elsevier. Ltd, 2011-08-23) Tesfa, Teklu K.; Tarboton, David G.; Watson, Daniel W.; Schreuders, Kimberly A.T.; Baker, Matthew; Wallace, Robert M.Land surface topography is one of the most important terrain properties which impact hydrological, geomorphological, and ecological processes active on a landscape. In our previous efforts to develop a soil depth model based upon topographic and land cover variables, we derived a set of hydrological proximity measures (HPMs) from a Digital Elevation Model (DEM) as potential explanatory variables for soil depth. These HPMs are variations of the distance up to ridge points (cells with no incoming flow) and variations of the distance down to stream points (cells with a contributing area greater than a threshold), following the flow path. The HPMs were computed using the D-infinity flow model that apportions flow between adjacent neighbors based on the direction of steepest downward slope on the eight triangular facets constructed in a 3 × 3 grid cell window using the center cell and each pair of adjacent neighboring grid cells in turn. The D-infinity model typically results in multiple flow paths between 2 points on the topography, with the result that distances may be computed as the minimum, maximum or average of the individual flow paths. In addition, each of the HPMs, are calculated vertically, horizontally, and along the land surface. Previously, these HPMs were calculated using recursive serial algorithms which suffered from stack overflow problems when used to process large datasets, limiting the size of DEMs that could be analyzed. To overcome this limitation, we developed a message passing interface (MPI) parallel approach designed to both increase the size and speed with which these HPMs are computed. The parallel HPM algorithms spatially partition the input grid into stripes which are each assigned to separate processes for computation. Each of those processes then uses a queue data structure to order the processing of cells so that each cell is visited only once and the cross-process communications that are a standard part of MPI are handled in an efficient manner. This parallel approach allows efficient analysis of much larger DEMs than were possible using the serial recursive algorithms. The HPMs given here may also have other, more general modeling applicability in hydrology, geomorphology and ecology, and so are described here from a general perspective. In this paper, we present the definitions of the HPMs, the serial and parallel algorithms used in their computation and their potential applications. ItemGetting a Second Chance with a University Education: Barriers & Opportunities(springer, 2019-04-08) Ross, Jeffrey; School of Criminal JusticeAs part of the prisoner reentry process, many formerly incarcerated individualsare choosing to enroll in universities to earn bachelor’s, master’s, and doctoral degrees. Some cannot immediately begin their studies and must take remedial classes. Oth- ers, because of preparations they have done before release, can start classes on the ﬁrst day of school. The following paper poses and attempts to answer six interrelated questions connected to excons taking classes at universities, the challenges they encounter, and ways to smooth the process for the universities in general and faculty, staﬀ, administrators, and other students in particular. ItemIf Not Us, Who? If Not Now, When?(Journal of the National Collegiate Honors Council, 2018-10) Yarrision, Betsy; Communication Design; Communication DesignLast year’s surprise hit of the television season was The Good Doctor, in which Freddie Highmore plays a gifted surgical resident who is also a high-functioning autistic. Critics speculate that it succeeded because audiences are hungry for good-outcome fantasy, or “warm bath” television. Fantasy is right. As much as we love watching Shaun Murphy show up not only all the other residents but all the attending physicians, we wouldn’t want to work with him in real life. Gifted students who can move through the K–12 curriculum so quickly that they can earn college-ready SAT scores at 11 or 12 are a prickly annoyance after elementary school, and many of them, especially boys, are outright casualties of the secondary school environment. They may sabotage their chances for admission to colleges that could challenge them—through poor attendance, low grades, and issues with authority, making an early exit from the educational system to excel as entrepreneurs or perhaps deliver pizza until they eventually succeed without a formal education or go back to school years later. In college, they are reluctant to enter yet another honors environment where they expect to be chased around with a “potentiometer.” How can they know that college is not high school—that, in college, they can do undergraduate research, take classes that are actually hard, and develop intellectual relationships with their professors that are truly collegial and rooted in mutual respect? You might think that gifted students are a natural fit for honors education, and they are, but they are nevertheless a marginalized minority because they are not always high achievers, their behavior is hard to predict or measure, and extrinsic motivators don’t work well with them; it is hard to justify giving them money or a scarce slot in a program with competitive admission unless they have a solid track record of proven academic success rather than just a glittering pile of test scores indicating amazing potential but little to no accomplishment. Honors programs tend to steer admission away from high test scores and low grades because high grades and class ranking do predict college success, at least early on. Yet we also recognize that honors programs have historically experienced high attrition and problems with student persistence. One of the wickedest of all wicked dilemmas for honors is whether we can predict performance from potential. ItemInformational Requirements for Transcriptional Regulation(2014-05-01) O'Neill, Patrick K.; Forder, Robert; Erill, IvanTranscription factors (TFs) regulate transcription by binding to specific sites in promoter regions. Information theory provides a useful mathematical framework to analyze the binding motifs associated with TFs but imposes several assumptions that limit their applicability to specific regulatory scenarios. Explicit simulations of the co-evolution of TFs and their binding motifs allow the study of the evolution of regulatory networks with a high degree of realism. In this work we analyze the impact of differential regulatory demands on the information content of TF-binding motifs by means of evolutionary simulations. We generalize a predictive index based on information theory, and we validate its applicability to regulatory scenarios in which the TF binds significantly to the genomic background. Our results show a logarithmic dependence of the evolved information content on the occupancy of target sites and indicate that TFs may actively exploit pseudo-sites to modulate their occupancy of target sites. In regulatory networks with differentially regulated targets, we observe that information content in TF-binding motifs is dictated primarily by the fraction of total probability mass that the TF assigns to its target sites, and we provide a predictive index to estimate the amount of information associated with arbitrarily complex regulatory systems. We observe that complex regulatory patterns can exert additional demands on evolved information content, but, given a total occupancy for target sites, we do not find conclusive evidence that this effect is because of the range of required binding affinities. ItemThe joy of pain and the pain of joy: In-group identification predicts schadenfreude and gluckschmerz following rival groups' fortunes(Motivation & Emotion, 2015-04) Hoogland, Charles; Schurtz, D. Ryan; Cooper, Chelsea; Combs, David; Brown, Edward; Smith, Richard; PsychologyFour studies examined how in-group identification in the domain of sports is associated with schadenfreude in reaction to another group's suffering or gluckschmerz in reaction to another group's good fortune. Schadenfreude increased as a function of in-group identification when the outgroup was a rival team rather than a non-rival team in Study 1. Study 2 showed that those who experience schadenfreude at learning of an outgroup player's injury will also tend to feel gluckschmerz when they learn of the player's recovery. Studies 3 and 4 replicated and extended these findings for both schadenfreude and gluckschmerz, and showed that neither the degree of severity of an injury nor the level of physical pain associated with the injury moderated the link between identification and both schadenfreude and gluckschmerz. Mediation analyses indicated that perceived in-group gain or loss, deservedness, and dislike were prime mediators of links between in-group identification and both emotions. ItemLack of Oversight and Credentialing Process for Digital Forensic Investigators(ISACA JOURNAL, 2018-08-28) Zahadat, Nima; School of Criminal Justice; Digital ForensicDespite the phenomenal growth in the digital world and crimes committed using digital techniques and tools, there are literally no foundational requirements to perform digital forensic investigations. While there is a slew of private and mostly for-profit organizations that sell training and certifications in regard to digital forensic credentials, there seems to be nothing of the kind at the federal and state levels in the United States. To understand the gravity of this, consider if attorneys did not attend law schools and were not required to take the bar exam where they practice and instead could take some private certification from a nonprofit or for-profit organization and then practice law. This is the precise situation when it comes to digital forensics investigators. ItemLong-Time Simulations on High Resolution Meshes to Model Calcium Waves in a Heart Cell(Society for Industrial and Applied Mathematics, 2008-10-13) Gobbert, Matthias K.A model for the flow of calcium on the scale of one heart cell is given by a system of time-dependent reaction-diffusion equations coupled by nonlinear reaction terms. Calcium ions enter into the cell at release units distributed throughout the cell and then diffuse. At each release unit, the probability for calcium to be released increases along with the concentration of calcium, thus creating a feedback loop of waves regenerating themselves repeatedly. The validation of this model requires simulations on the time scale of several repeated waves and on the spatial scale of the entire cell. This requires long-time studies on spatial meshes that need to have a high resolution to resolve the positions of the calcium release units throughout the entire cell. We detail the development of a special-purpose numerical method and parallel implementation for this problem. Parallel performance studies demonstrate the scalability of the implementation on a distributed-memory cluster with low-latency interconnect. Convergence studies verify convergence to analytical expectations and confirm the appropriateness of all numerical parameters. Application studies on the desired time and length scales confirm that the model exhibits the desired feedback mechanism for calcium currents through the release units at suitable high levels, but the long-time studies demonstrate also that the current model with its present parameters leads to excessive calcium concentrations over time. This phenomenon could only be observed using a computational method able to reach laboratory scale final times for a domain on the scale of a complete cell. ItemMaking teacher PD effective using the PrimeD framework.(New England Mathematics Journal, 2017) Rakes, Christopher R.; Bush, Sarah B.; Mohr-Schroeder, Margaret J.; Ronau, Robert N.; Saderholm, Jon ItemMarginalization and Hope: Personal Narratives of Previously Incarcerated Mothers(Bradford: Demeter Press, 2015-01) Wyatt-Nichol, Heather; Seabrook, RenitaIncarceration among women in America's correctional system has dramatically increased over the past several decades, an increase of approximately ten percent each year (Laux et al.). Not surprisingly the majority of imprisoned when, approximately 70 percent, are mothers with dependent children (Poehlmann). Women have an average of two to three children living with them prior to incarceration (Laux et al.; Polluck). Within state institutions, 64 percent of incarcerated women had at least one child under the age of eighteen prior to incarceration —the number increases to 84 percent in federal prisons (Laux et al.; Figueira-McDonough and Sarri; Morash and Schream; Moses; Snyder; Tuerk and Loper). ItemA matrix-focused structure-activity and binding site flexibility study of quinolinol inhibitors of botulinum neurotoxin serotype A(Bioorganic & Medicinal Chemistry Letters, 2017-02-01) Harrell, William A. Jr.; Vieira, Rebecca C.; Ensel, Susan M.; Montgomery, Vicki; Guernieri, Rebecca; Eccard, Vanessa S.; Campbell, Yvette; Roxas-Duncan, Virginia; Cardellina, John H. II; Webb, Robert P.; Smith, Leonard A.; ChemistryOur initial discovery of 8-hydroxyquinoline inhibitors of BoNT/A and separation/testing of enantiomers of one of the more active leads indicated considerable flexibility in the binding site. We designed a limited study to investigate this flexibility and probe structure-activity relationships; utilizing the Betti reaction, a 36 compound matrix of quinolinol BoNT/A LC inhibitors was developed using three 8-hydroxyquinolines, three heteroaromatic amines, and four substituted benzaldehydes. This study has revealed some of the most effective quinolinol-based BoNT/A inhibitors to date, with 7 compounds displaying IC50 values ⩽1μM and 11 effective at ⩽2μM in an ex vivo assay. ItemMinimally invasive technique for measuring transdermal glucose with a fluorescent biosensor(Springer Berlin Heidelberg, 2018-08-17) Brown, Sheniqua; Zambrana, Paige N.; Ge, Xudong; Bagdure, Dayanand; Stinchcomb, Audra L.; Rao, Govind; Tolosa, LeahThere is a need for blood glucose monitoring techniques that eliminate the painful and invasive nature of current methods, while maintaining the reliability and accuracy of established medical technology. This research aims to ultimately address these shortcomings in critically ill pediatric patients. Presented in this work is an alternative, minimally invasive technique that uses microneedles (MN) for the collection of transdermal glucose (TG). Due to their comparable skin properties, diffusion studies were performed on full thickness Yucatan miniature pig skin mounted to an in-line diffusion flow cell and on different skin sites of human subjects. Collected TG samples were measured with a L255C mutant of the E. coli glucose-binding protein (GBP) with an attached fluorescent probe. The binding constant (Kd = 0.67 μM) revealed the micromolar sensitivity and high selectivity of the his-tagged GBP biosensor for glucose, making it suitable for TG measurements. In both the animal and human models, skin permeability and TG diffusion across the skin increased with MN application. For intact and MN-treated human skin, a significant positive linear correlation (r > 0.95, p < 0.01) existed between TG and BG. The micromolar sensitivity of GBP minimized the volume required for interstitial fluid glucose analysis allowing MN application time (30 s) to be shortened compared to other studies. This time reduction can help in eliminating skin irritation issues and improving practical use of the technique by caregivers in the hospital. In addition, the his-tagged optical biosensor used in this work can be immobilized and used with a portable sensing fluorometer device at the point of care (POC) making this minimally invasive technology more ideal for use in the pediatric intensive care unit.
