Assessing the Impact of the Concrete Canoe and Steel Bridge Competitions on Civil Engineering Technology Students

The new accreditation criteria (TC2K) of the Technology Accreditation Commission of ABET require an assessment of Program Intended Learning Outcomes. Some of the learning outcomes required by the “a” through “k” and the Civil criteria of TC2K include leadership skills, teamwork skills, project management skills, communication skills, and design and construction skills. The American Society of Civil Engineers (ASCE) and the American Institute for Steel Construction (AISC) sponsors regional and national concrete canoe and steel bridge competitions on an annual basis. The Civil Engineering Technology (CET) students at the Rochester Institute of Technology (RIT) have participated in these competitions for the past nine years. These competitions give students a chance to apply what they have learned in the classroom. To assess the impact of the concrete canoe and steel bridge competitions on student learning and development, the authors carried out a survey of current students and graduates of the CET program at RIT who have been members of the concrete canoe and steel bridge teams. The issues addressed in our survey include the following: impact of these activities on leadership skills, communication skills, teamwork skills, design and construction skills, project management skills, confidence levels, students’ enthusiasm for the profession, and a positive image and exposure for students and CET programs. In this paper, we discuss the results of this survey and some of the challenges to student participation in these non-credit activities at RIT, and present some suggestions for enhancing the level of student participation

The sampling and estimation of marine paleodiversity patterns: implications of a Pliocene model

Abstract.-Data that accurately capture the spatial structure of biodiversity are required for many paleobiological questions, from assessments of changing provinciality and the role of geographic ranges in extinction and originations, to estimates of global taxonomic or morphological diversity through time. Studies of temporal changes in diversity and global biogeographic patterns have attempted to overcome fossil sampling biases through sampling standardization protocols, but such approaches must ultimately be limited by available literature and museum collections. One approach to evaluating such limits is to compare results from the fossil record with models of past diversity patterns informed by modern relationships between diversity and climatic factors. Here we use present-day patterns for marine bivalves, combined with data on the geologic ages and distributions of extant taxa, to develop a model for Pliocene diversity patterns, which is then compared with diversity patterns retrieved from the literature as compiled by the Paleobiology Database (PaleoDB). The published Pliocene bivalve data (PaleoDB) lack the first-order spatial structure required to generate the modern biogeography within the time available (,3 Myr). Instead, the published data (raw and standardized) show global diversity maxima in the Tropical West Atlantic, followed closely by a peak in the cooltemperate East Atlantic. Either today's tropical West Pacific diversity peak, double that of any other tropical region, is a purely Pleistocene phenomenon-highly unlikely given the geologic ages of extant genera and the topology of molecular phylogenies-or the paleontological literature is such a distorted sample of tropical Pliocene diversity that current sampling standardization methods cannot compensate for existing biases. A rigorous understanding of large-scale spatial and temporal diversity patterns will require new approaches that can compensate for such strong bias, presumably by drawing more fully on our understanding of the factors that underlie the deployment of diversity today

Prospective, Randomized, Controlled Trial of Tissue Adhesive (2-Octylcyanoacrylate) vs Standard Wound Closure Techniques for Laceration Repair

Objective: To compare a new tissue adhesive, 2-octylcyanoacrylate, with standard wound closure techniques for the repair of traumatic lacerations. Methods: A prospective, randomized, controlled clinical trial enrolled consecutive patients >1 year of age with non-bite, non-crush-induced lacerations who presented 3 months) was assessed by physicians using a previously validated categorical cosmetic scale and by patients using a 100-mm visual analog scale. Results : There were 63 patients randomized to the octylcyanoacrylate group and 61 patients treated with standard wound closure techniques. The 2 treatment groups were similar with respect to age, gender, race, medical history, and wound characteristics. At the 5-to-10-day follow-up, only 1 wound was infected and only 2 wounds required reclosure due to dehiscence. These 3 patients received treatment with octylcyanoacrylate. At long-term follow-up, the cosmetic appearances were similar according to the patients (octylcyanoacrylate, 83.8 ± 19.4 mm vs standard techniques, 82.5 ± 17.6 mm; p = 0.72) and the physicians (optimal cosmetic appearance, 77% vs 80%; p = 0.67). Conclusions: Wounds treated with octylcyanoacrylate and standard wound closure techniques have similar cosmetic appearances 3 months later.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75580/1/j.1553-2712.1998.tb02590.x.pd

An Orientation Program for Vertical Transfers in Engineering and Engineering Technology

This paper reports on a scholarship program funded by the National Science Foundation that focuses on students who transfer at the 3rd -year level from 2-year schools to the engineering and engineering technology BS programs at our university. The objectives of the program are to: (i) expand and diversify the engineering/technology workforce of the future, (ii) develop linkages and articulations with 2-year schools and their S-STEM (Scholarships in Science, Technology, Engineering and Mathematics) programs, (iii) provide increased career opportunities and job placement rates through mandatory paid co-op experiences, and (iv) serve as a model for other universities to provide vertical transfer students access to the baccalaureate degree. The program is in its third year. It recruited its first group of 25 students in Fall 2017, and another group of 27 students in Fall 2018. We hope to recruit 26 more students in Fall 2019 for a total of 78 vertical transfers. The goal is to retain and graduate at least 95% of these scholars. To enhance the success of these scholars, a zero-credit six-week orientation course was developed in Fall 2017 focusing on four dimensions of student wellness: academic, financial, social, and personal. This paper describes the development of this course, its content, and the modifications that were made to the course for Fall 2018. The paper will also address the research conducted in order to generate knowledge about the program elements that will be essential for the success of vertical transfer programs at other universities. Two research instruments are described: an online survey and a focus group interview that were developed, and administered to the transfer scholars in their first year. Initial findings concerning students’ experiences at their 2-year schools, their reason for transferring, their experience in transferring as well as their initial conceptions of what life at a 4-year institution will be like are presented

Tiered Approach to Resilience Assessment

Regulatory agencies have long adopted a three-tier framework for risk assessment. We build on this structure to propose a tiered approach for resilience assessment that can be integrated into the existing regulatory processes. Comprehensive approaches to assessing resilience at appropriate and operational scales, reconciling analytical complexity as needed with stakeholder needs and resources available, and ultimately creating actionable recommendations to enhance resilience are still lacking. Our proposed framework consists of tiers by which analysts can select resilience assessment and decision support tools to inform associated management actions relative to the scope and urgency of the risk and the capacity of resource managers to improve system resilience. The resilience management framework proposed is not intended to supplant either risk management or the many existing efforts of resilience quantification method development, but instead provide a guide to selecting tools that are appropriate for the given analytic need. The goal of this tiered approach is to intentionally parallel the tiered approach used in regulatory contexts so that resilience assessment might be more easily and quickly integrated into existing structures and with existing policies

Top-Level Categories of Constitutively Organized Material Entities - Suggestions for a Formal Top-Level Ontology

Application oriented ontologies are important for reliably communicating and managing data in databases. Unfortunately, they often differ in the definitions they use and thus do not live up to their potential. This problem can be reduced when using a standardized and ontologically consistent template for the top-level categories from a top-level formal foundational ontology. This would support ontological consistency within application oriented ontologies and compatibility between them. The Basic Formal Ontology (BFO) is such a foundational ontology for the biomedical domain that has been developed following the single inheritance policy. It provides the top-level template within the Open Biological and Biomedical Ontologies Foundry. If it wants to live up to its expected role, its three top-level categories of material entity (i.e., 'object', 'fiat object part', 'object aggregate') must be exhaustive, i.e. every concrete material entity must instantiate exactly one of them.By systematically evaluating all possible basic configurations of material building blocks we show that BFO's top-level categories of material entity are not exhaustive. We provide examples from biology and everyday life that demonstrate the necessity for two additional categories: 'fiat object part aggregate' and 'object with fiat object part aggregate'. By distinguishing topological coherence, topological adherence, and metric proximity we furthermore provide a differentiation of clusters and groups as two distinct subcategories for each of the three categories of material entity aggregates, resulting in six additional subcategories of material entity.We suggest extending BFO to incorporate two additional categories of material entity as well as two subcategories for each of the three categories of material entity aggregates. With these additions, BFO would exhaustively cover all top-level types of material entity that application oriented ontologies may use as templates. Our result, however, depends on the premise that all material entities are organized according to a constitutive granularity
