Two new kirkocystid mitrate stylophorans (Echinodermata, Homalozoa) and a new possible solute (Echinodermata, Homalozoa) are described from the Early Ordovician of the western United States. The mitrates are among the earliest members of their clade to appear near the beginning of the Ordovician Radiation. Anatifopsis ninemilensis new species comes from the Ninemile Shale in central Nevada and the McKelligon Canyon Formation in west Texas. Anatifopsis fillmorensis new species comes from the middle Fillmore Formation in western Utah and a Ninemile Shale equivalent limestone bed in southern Nevada. The possible solute Drepanocystis dubius new genus new species from the lower Wah Wah Limestone in western Utah, shows unusual morphology with an elongate theca and a long arm shaped like a sickle.

For many years the earliest record of the class Crinoidea was a single late Tremadocian genus. In the past decade, five crinoid genera were described from the early and middle Tremadocian, near the base of the Ordovician. Together these six genera represent a diverse assemblage with all but one expressing existing subclass apomorphies. Two of the recently described genera were initially assigned to their own order (plesion) Protocrinoida but not to a subclass. Here they are placed in the camerates based on apomorphies of the tegmen complex. Protocrinoids exhibit plesiomorphies unlike typical camerates. Two genera group with cladids, one expressing dendrocrinine apomorphies and the other cyathocrinine. One genus is placed within disparids, with iocrinid apomorphies. Based on its ancient age and trait mosaic, the protocrinoid Titanocrinus is designated as outgroup in a phylogenetic analysis using all other Early Ordovician and select Middle Ordovician taxa as an ingroup. Character compilation and phylogenetic analysis posit early class-level plesiomorphies inherited from an unknown ancestry but lost during subsequent crinoid evolution. Class-level apomorphies also emerge, some of which were subsequently lost and others retained. Results are generally robust and consistent with earlier subdivisions of the class, but supporting lower rank reorganizations. Strong support for the camerate branch low in the crinoid tree mirrors findings of earlier workers. Cladids branch from a series of intermediate nodes and disparids nest highest. Branching of disparids from cladids could be homoplastic. © 2012 The Paleontological Society.

Alphacrinus mansfieldi new genus and species from the Middle Tremadoc Series (Early Ibexian), near the base of the Ordovician, is the oldest known disparid crinoid. A new family, Alphacrinidae, receives this monospecific genus. Alphacrinus's character mosaic includes primitive traits unknown among other disparids, auguring for disparid origin from a more complexly plated, less standardized antecedent, and echoing the evolutionary progression documented for camerates and cladids. Disparids are diagnosed as those crinoids expressing an arm-like branch from the C ray. Morphologic progression indicates this distinctive trait evolved by modification of CD interray plates, not as an outgrowth from the C ray. © 2010 The Paleontological Society.

It is often said that a crisis is an opportunity in disguise. When faced with declining enrollments, the Electronic Engineering Technology (EET) faculty at Rock Valley College responded by tapping into two modern trends: the burgeoning field of sustainable energy systems, and the move towards online education. By adding a sustainable energy emphasis to the EET degree, the department prepares its students for the next generation of energy technology. By modifying its courses to be delivered in a hybrid format (lectures online, labs in person), the program offers a compatible option for students who have jobs and families that require more flexible course scheduling. There is a bold new mission for EET in the area of alternative energy. Sustainable Energy Systems (SES) professionals are needed to advance our nation's move toward freedom from fossil fuels. A curriculum has been designed based on the alternative energy job task analysis orchestrated by the Electronics Technicians Association, International. The resulting curriculum provides Alternative-Energy Integrator graduates and embeds a student learning outcomes assessment of that curriculum through industry-recognized, third-party certifications. The challenge to EET educators is to push the envelope of their comfort zones to tackle new interdisciplinary imperatives. Many students today are very comfortable learning from the internet. Hybrid educational experiences permit the lectures, and additional resources such as videos, to be delivered asynchronously, but paced to ensure timely completion. Laboratory activities are still conducted to provide students with hands-on experiences and direct interaction with their professors and other students. The design of alternative-format hybrid classes leads inherently to a detailed, concise, week-by-week course construction. This paper includes five sections: (1) Alternative Energy - A Comprehensive Overview, (2) Designing a Curriculum for Assessment, (3) The Pros and Cons of a Hybrid Course Design, (4) The Critical Issues of Enrollments and Employment, and (5) Conclusions and Future Development. The SES degree program curriculum at Rock Valley College finishes its first two years of delivery in June 2011. © 2011 American Society for Engineering Education.

The class Somasteroidea Spencer, 1951, is basal within the subphylum Asterozoa. Members are most readily recognized by presence of series of rod-like so-called virgal ossicles extending laterally from each ambulacral ossicle. Five somasteroid genera are recognized and assigned to two families. Four genera are Gondwanan, three of these (Chinianaster, Thoralaster, Villebrunaster) from the Lower Ordovician Tremadocian of France and one (Archegonaster) from the Middle Ordovician upper Darriwilian of the Czech Republic. The fifth genus, Ophioxenikos, is Laurentian from the Floian of Nevada. Catervaparmaster, previously assigned to the Somasteroidea, is left in open nomenclature; absence of virgal-series ossicles favors a lineage apart from the principal asterozoan clades. Asterozoan fossils are readily separated from fossils of other echinoderm groups. The subphylum therefore is thought to be monophyletic, its ancestry unknown. Skeletonized representatives of the four major asterozoan clades first occur through a relatively narrow Early Ordovician stratigraphic interval. Robust skeletons therefore are thought to have evolved after a time of unknown duration including only lineages that were no more than weakly calcified. The French occurrences are from a relatively deep distal shelf setting on soft substrates whereas the Nevada occurrence was in a shallower, active setting. Differences document early ecologic diversification. © 2015 The Paleontological Society.

At present, a debate in the paleontologic literature focuses on whether or not the immediate ancestry of the Crinoidea lies in an unidentified member of the Blastozoa, which includes eocrinoids and an assemblage known variously as the "cystoids". Those proposing to derive crinoids from within the blastozoans have recently argued for homologies in the construction of the oral region of certain derived taxa from both groups. An opposing viewpoint, outlined here, finds evidence that aside from plesiomorphies, proposed similarities are superficial and homoplastic. We suggest these superficialities represent convergent adaptive strategies. Earliest crinoids express ambulacral traits unlike any blastozoan but that are expressed in the only other pentaradial echinoderms with a known record early enough to be considered in the context of crinoid origins, edrioasteroids and edrioasteroid-like stem echinoderms. © 2016 T.E.

One of the earliest isorophid edrioasteroids from the upper Middle Cambrian-lower Upper Cambrian (upper part of Series 3-lower part of the Furongian Series) of northern Iran is described. It has unusual branched ambulacra, which extend beyond the theca almost to the marginal rim. These unusual features reflect the latent possibility of appearance of separated from the theca and even branching food-gathering appendages, such as arms in crinoids and brachials in blastozoans, in common ancestor of all radially symmetrical echinoderms. © 2014 Pleiades Publishing, Ltd.

Two new Early Ordovician crinoids have been discovered in Gondwanan rocks of northwest Argentina. Ramseyocrinus argentinus n. sp., among the most complete for the genus, AIDS in reconstructing key morphology. Ramseyocrinus is unorthodox with just four radials forming the entire cup, these articulating to five arms above and a tetrameric stem below. Evidence is presented radials comprise A, B, D, and E ray elements (C absent) with B and D radials adjoining to form a compound facet for the C arm. Thus the cup entirely lacks posterior plating; an elongate anal sac projects from the CD tegmen region alongside the C arm. Cup synapomorphies closely link Ramseyocrinus and the Middle Ordovician Tetragonocrinus; inclusion of this clade within disparids is tenuous. Quechuacrinus ticsa n. gen. and sp., increases the paleogeographic range of reteocrinid camerates, previously documented only from Laurentia. This taxon expresses synapomorphies characterizing the Late Ordovician Reteocrinus, demonstrating the antiquity of this morphotype. Copyright © 2015, The Paleontological Society.

Candidemia is a cause of significant morbidity and mortality in neonates and children. Risk factors for candidemia include prolonged stay in the intensive care unit, prior antibiotic therapy, immunosuppression related to malignancy, transplantation, use of immunosuppressants or steroids, neutropenia, need for mechanical ventilation, use of vasopressors, recent surgery (especially gastrointestinal), intravenous catheters and receipt of total parenteral nutrition. Candida albicans followed by C. parapsilosis are the most common species causing candidemia in children. Clinicians must be aware of the risk factors for candidemia and the local epidemiology of Candida species in order to direct antifungal therapy appropriately. Ongoing efforts to minimize health care-associated candidemia through infection control practices, judicious antimicrobial use and antifungal prophylaxis in appropriate situations are important to reducing Candida-associated morbidity and mortality in neonates and children. © 2012 Springer Science+Business Media New York.

Patients with complex medical conditions require collaboration among multiple health care providers, and dental hygienists must be prepared to communicate effectively with medical providers to provide comprehensive quality patient care. The aim of this study was to assess U.S. dental hygiene students' attitudes about interprofessional collaboration (IPC) and identify any differences based on age, year in program, and program location. Participants were limited to students enrolled in dental hygiene associate degree programs across the United States. In response to an email soliciting participation sent to all dental hygiene program directors, 504 students completed the Interdisciplinary Education Perception Scale (IEPS) online (response rate could not be calculated). The IEPS is a validated survey that measures attitudes about interprofessional collaboration. The majority of the respondents were female (97%) and under 30 years of age (74.6%). Their mean scores indicated positive attitudes about IPC. There were no statistically significant differences in scores by age (p=0.700) or program location (p=0.527). There were also no statistically significant differences between first- and second-year students for total mean scores (p=0.106); for the competency and autonomy subscale (p=0.125); and for the perception of actual cooperation subscale (p=0.890). There was a statistically significant difference between first- and second-year students on the perception of actual cooperation subscale, with first-year students scoring higher than second-year students (p=0.016). This study's findings of positive attitudes about IPC and that age and program location had little bearing on the responses suggest that associate degree dental hygiene students may welcome the interprofessional education that will prepare them for practice in the future.
