Founding Practice: Examining Intercollegiate Competition as Assessment
Intercollegiate forensics is, at its core, a form of teaching. Like other pedagogical elements within higher education, the practice is now, and will increasingly be, subject to institutional assessment requirements in higher education. The conventional argument that the evaluation processes inherent in intercollegiate forensics competition will demonstrate the effectiveness of teaching and learning in forensics pedagogy is false. The assessment practices within the frame-work of competitions are part of the teaching processes. Forensics pedagogy, therefore, must align itself with institutional assessment components. This essay argues for the roots of that alignment to be tied to an academic learning compact that seeks to meet the requirements of institutional assessment and clarify the focus of the collection of scholars, educators and students that comprise the intercollegiate forensics community
Maintaining and Enhancing Institutional Relevance: Long-term Program Sustainability in an Era of Increased Intra-Institutional Competition for Resources
The preservation and growth of intercollegiate forensic programs does not, and should not, depend on the singular factor of competitive results. The value of a program is rooted, in great part, in intra-institutional factors. This paper puts forth an assertion related to increasing the institutional value of forensics programs. Emphasis is placed on expanding the scope of the program goals and framing the success of a program on a non-competitive basis. The intra-institutional framing of program identity as centers of excellence functions as a central tenet
Re-examining Competition and Education in Collegiate Forensics: Establishing the Need for a Pedagogical Prerogative Perspective
The authors examine the dominant metaphors used to guide collegiate forensics practice during the last four decades. The interplay between education and competition serve as a focus for the analysis. The authors establish the need for a pedagogical prerogative perspective as a means of enhancing the educational value of intercollegiate individual events
WHAT WE ARE TRYING TO TEACH Reconnecting Collegiate Forensics to the Communication Discipline
SPECIAL REPORT: National Forensic Association Report on Pedagogy —2010. The document features descriptive analysis of prerogatives for collegiate forensics pedagogy organized in two tiers. Each section is fashioned as a series of “statements of purpose.” The term purpose, in this regard, is related to roots and motivations for teaching. This document recognizes the shaping of best practices in forensics pedagogy as a central goal for the collegiate forensics community. The full measure of the components in each tier work to shape the purpose of teaching and coaching practices that resist replication of past performances and move toward speechmaking and performance development founded in the root principles and rhetorical foundations celebrated in the scholarly and professional study of human communication. A third tier that would address each event individually is strongly suggested during the course of future development
Signs of the 2009 Influenza Pandemic in the New York-Presbyterian Hospital Electronic Health Records
Background
In June of 2009, the World Health Organization declared the first influenza pandemic of the 21st century, and by July, New York City's New York-Presbyterian Hospital (NYPH) experienced a heavy burden of cases, attributable to a novel strain of the virus (H1N1pdm).
Methods and Results
We present the signs in the NYPH electronic health records (EHR) that distinguished the 2009 pandemic from previous seasonal influenza outbreaks via various statistical analyses. These signs include (1) an increase in the number of patients diagnosed with influenza, (2) a preponderance of influenza diagnoses outside of the normal flu season, and (3) marked vaccine failure. The NYPH EHR also reveals distinct age distributions of patients affected by seasonal influenza and the pandemic strain, and via available longitudinal data, suggests that the two may be associated with distinct sets of comorbid conditions as well. In particular, we find significantly more pandemic flu patients with diagnoses associated with asthma and underlying lung disease. We further observe that the NYPH EHR is capable of tracking diseases at a resolution as high as particular zip codes in New York City.
Conclusion
The NYPH EHR permits early detection of pandemic influenza and hypothesis generation via identification of those significantly associated illnesses. As data standards develop and databases expand, EHRs will contribute more and more to disease detection and the discovery of novel disease associations
The concluding chapter: Recircumscription of Goodenia (Goodeniaceae) to include four allied genera with an updated infrageneric classification
© 2020. Close scrutiny of Goodenia (Goodeniaceae) and allied genera in the \u27Core Goodeniaceae\u27 over recent years has clarified our understanding of this captivating group. While expanded sampling, sequencing of multiple regions, and a genome skimming reinforced backbone clearly supported Goodenia s.l. as monophyletic and distinct from Scaevola and Coopernookia, there appears to be no synapomorphic characters that uniquely characterise this morphologically diverse clade. Within Goodenia s.l., there is strong support from nuclear, chloroplast and mitochondrial data for three major clades (Goodenia Clades A, B and C) and various subclades, which lead to earlier suggestions for the possible recognition of these as distinct genera. Through ongoing work, it has become evident that this is impractical, as conflict remains within the most recently diverged Clade C, likely due to recent radiation and incomplete lineage sorting. In light of this, it is proposed that a combination of morphological characters is used to circumscribe an expanded Goodenia that now includes Velleia, Verreauxia, Selliera and Pentaptilon, and an updated infrageneric classification is proposed to accommodate monophyletic subclades. A total of twenty-five new combinations, three reinstatements, and seven new names are published herein including Goodenia subg. Monochila sect. Monochila subsect. Infracta K.A. Sheph. subsect. nov. Also, a type is designated for Goodenia subg. Porphyranthus sect. Ebracteolatae (K. Krause) K.A. Sheph. comb. et stat. nov., and lectotypes or secondstep lectotypes are designated for a further three names
The effect of adherence to spectacle wear on early developing literacy: a longitudinal study based in a large multi-ethnic city, Bradford, UK
YesObjectives: To determine the impact of adherence to
spectacle wear on visual acuity (VA) and developing
literacy following vision screening at age 4–5 years.
Design: Longitudinal study nested within the Born in
Bradford birth cohort.
Setting and participants: Observation of 944 children:
432 had failed vision screening and were referred
(treatment group) and 512 randomly selected (comparison
group) who had passed (<0.20 logarithm of the minimum
angle of resolution (logMAR) in both eyes). Spectacle wear
was observed in school for 2 years following screening
and classified as adherent (wearing spectacles at each
assessment) or non-adherent.
Main outcome measures: Annual measures of VA
using a crowded logMAR test. Literacy was measured by
Woodcock Reading Mastery Tests-Revised subtest: letter
identification.
Results: The VA of all children improved with increasing
age, −0.009 log units per month (95% CI −0.011 to
−0.007) (worse eye). The VA of the adherent group
improved significantly more than the comparison group, by
an additional −0.008 log units per month (95% CI −0.009
to −0.007) (worse eye) and −0.004 log units per month
(95% CI −0.005 to −0.003) in the better eye. Literacy was
associated with the VA, letter identification (ID) reduced
by −0.9 (95% CI −1.15 to −0.64) for every one line (0.10
logMAR) fall in VA (better eye). This association remained
after adjustment for socioeconomic and demographic
factors (−0.33, 95% CI −0.54 to −0.12). The adherent
group consistently demonstrated higher letter-ID scores
compared with the non-adherent group, with the greatest
effect size (0.11) in year 3.
Conclusions: Early literacy is associated with the level of
VA; children who adhere to spectacle wear improve their
VA and also have the potential to improve literacy. Our
results suggest failure to adhere to spectacle wear has
implications for the child’s vision and education.AB is funded by a National Institute for Health Research Post- Doctoral Fellowship Award (PDF-2013-06-050).

Co-evolutionary analysis suggests a role for TLR9 in papillomavirus restriction
Upon infection, DNA viruses can be sensed by pattern recognition receptors (PRRs) leading to the activation of type I and III interferons, aimed at blocking infection. Therefore, viruses must inhibit these signaling pathways, avoid being detected, or both. Papillomavirus virions are trafficked from early endosomes to the Golgi apparatus and wait for the onset of mitosis to complete nuclear entry. This unique subcellular trafficking strategy avoids detection by cytoplasmic PRRs, a property that may contribute to establishment of infection. However, as the capsid uncoats within acidic endosomal compartments, the viral DNA may be exposed to detection by toll-like receptor (TLR) 9. In this study we characterize two new papillomaviruses from bats and use molecular archeology to demonstrate that their genomes altered their nucleotide composition to avoid detection by TLR9, providing evidence that TLR9 acts as a PRR during papillomavirus infection. Furthermore, we demonstrate that TLR9, like other components of the innate immune system, is under evolutionary selection in bats, providing the first direct evidence for co-evolution between papillomaviruses and their hosts
Di-aryl guanidinium derivatives: Towards improved α2-Adrenergic affinity and antagonist activity
Compounds with excellent receptor engagement displaying alpha(2)-AR antagonist activity are useful not only for therapeutic purposes (e.g. antidepressants), but also to help in the crystallization of this particular GPCR. Therefore, based on our broad experience in the topic, we have prepared eighteen di-aryl (phenyl and/or pyridin-2-yl) mono- or di-substituted guanidines and 2-aminoimidazolines. The in vitro alpha(2)-AR binding affinity experiments in human brain tissue showed the advantage of a 2-aminoimidazolinium cation, a di-arylmethylene core, a conformationally locked pyridin-2-yl-guanidine and a di-substituted guanidinium to achieve good alpha(2)-AR engagement. After different in vitro [S-35]GTP gamma S binding experiments in human prefrontal cortex tissue, it was possible to identify that compounds 7a, 7b and 7c were alpha(2)-AR partial agonist, whereas 8h was a potent alpha(2)-AR antagonist. Docking and MD studies with a model of alpha(2A)-AR and two crystal structures suggest that antagonism is achieved by compounds carrying a di-substituted guanidine which substituent occupy a pocket adjacent to TM5 without engaging S200(5.42) or S204(5.46), and a mono-substituted cationic group, which favorably interacts with E94(2.65).

S4S8-RPA phosphorylation as an indicator of cancer progression in oral squamous cell carcinomas.
Oral cancers are easily accessible compared to many other cancers. Nevertheless, oral cancer is often diagnosed late, resulting in a poor prognosis. Most oral cancers are squamous cell carcinomas that predominantly develop from cell hyperplasias and dysplasias. DNA damage is induced in these tissues directly or indirectly in response to oncogene-induced deregulation of cellular proliferation. Consequently, a DNA Damage response (DDR) and a cell cycle checkpoint is activated. As dysplasia transitions to cancer, proteins involved in DNA damage and checkpoint signaling are mutated or silenced decreasing cell death while increasing genomic instability and allowing continued tumor progression. Hyperphosphorylation of Replication Protein A (RPA), including phosphorylation of Ser4 and Ser8 of RPA2, is a well-known indicator of DNA damage and checkpoint activation. In this study, we utilize S4S8-RPA phosphorylation as a marker for cancer development and progression in oral squamous cell carcinomas (OSCC). S4S8-RPA phosphorylation was observed to be low in normal cells, high in dysplasias, moderate in early grade tumors, and low in late stage tumors, essentially supporting the model of the DDR as an early barrier to tumorigenesis in certain types of cancers. In contrast, overall RPA expression was not correlative to DDR activation or tumor progression. Utilizing S4S8-RPA phosphorylation to indicate competent DDR activation in the future may have clinical significance in OSCC treatment decisions, by predicting the susceptibility of cancer cells to first-line platinum-based therapies for locally advanced, metastatic and recurrent OSCC
