Using Blended Learning to Enhance the Experience of Students in Built Environment Related Degree Programs

Blended learning was introduced into the Construction Management programme in the School of Surveying and Construction Management at the Dublin Institute of Technology in 2016. The module has traditionally been delivered by face-to-face teaching but online delivery has been facilitated using the Virtual Learning Environment (Blackboard) which has enabled a more blended approach to academic instruction. This innovative change to module provision has also provided an opportunity to enhance the student learning experience within the School through a more flexible teaching and learning environment. In this paper, the design, development and implementation of blended learning into a Construction Technology module is outlined and we examine the student experiences of the blended learning approach, in particular their perspectives on online delivery and the pedagogical benefits of this approach. The article highlights areas that require further research and outlines elements of the module that could be improved to enhance future provision. The paper will be of value to higher education practitioners and in particular all stakeholders in the new Technological University Dublin (TU Dublin)[1] in terms of the University vision for a digital campus; which will enable flexible, online and blended learning provision.

Leveraging Intelligent Building Infrastructure for Event Response

The number of attacks against occupied commercial buildings has increased dramatically around the world and in the United States. These attacks have included active shooters, kinetic devices, and hazardous (i.e., chemical or biological) agents. Typical commercial buildings have no systems to deal with these threats. Even iconic buildings rely primarily on restricted access to provide security. Video cameras are often present but are used primarily for forensics after an event has occurred. However, advanced systems that enable intelligent and connected buildings can be leveraged along with sensor technology to enable detection, notification and response to attacks. These same systems can also be used to enhance response to other emergency events such as grid outages, extreme weather, and earthquakes. This paper will present current research showing how Intelligent Building Technology can be leveraged to provide automated response and situational awareness to attacks and other emergency event situations. Results from whole-building modeling and full-scale testing will be presented for one type of threat. Specifically, CONTAM model results validated with experimental data from a well-instrumented 50,000 sqft testbed building will be presented to demonstrate the capability of using intelligent building infrastructure to affect dispersion of a chemical or biological agent inside a commercial office building

A Retrospective Analysis of Opioid Consumption Among Different Orthopedic Surgeons for Total Joint Replacement

Background: Throughout the world, baby boomers reaching their sixth, seventh, and eighth decade of life are requiring a significant number of joint replacements—hips and knees. Due to the increasing number of joint replacements, it is important to find a multi-modal approach (MMA) to control pain, reduce the amount of opioid consumption, and improve patient satisfaction. Purpose: The purpose of this study was to evaluate the intraoperative, postoperative, and total opioid consumption of patients undergoing total hip and knee replacements in an effort to develop a multi-modal approach to decrease opioid consumption, minimize adverse effects secondary to narcotic administration, and to achieve better pain control. This MMA was achieved by administering oxycodone, gabapentin, celecoxib, and acetaminophen starting before surgical incision. Methods: The study sample consisted of 192 patients undergoing total hip and knee replacements over a 10-month period between June 2012 and March 2013 at UMASS Memorial performed by five orthopedic surgeons. The main objective was to record intraoperative, postoperative, total opioid consumption, and patient satisfaction amongst these patients. Furthermore, the patients were subdivided based on the type of procedure (hip vs knee), type of anesthetic (general vs spinal), and the presence or absence of an indwelling catheter to deliver anesthetic (catheter vs no catheter). Results: The data showed a large variability among the surgeons in regards to the amount of opioid used intraoperatively, postoperatively and total opioid consumption. In terms of type of anesthetic, the patients undergoing spinal anesthesia used statistically significantly less opioids intraoperatively but not postoperatively, compared to general anesthesia. As for catheter use with general and spinal anesthesia, surprisingly, there was no significant difference in opioid consumption compared to the non-catheter counterpart. Furthermore, there seems to be no correlation between body mass index (BMI) and intraoperative or postoperative opioid use. Patient satisfaction was another variable that showed no correlation with opioid use intraoperatively or postoperatively. In terms of age, the data suggests that older patients use less opioids postoperatively in both hip and knee replacements. Conclusions: Our results quantitatively show spinal anesthesia to be far superior than general anesthesia in both joint replacements. Spinal anesthesia provides better pain control intraoperatively which allows one to use less opioids, thereby minimizing the adverse side effects of narcotic administration which include respiratory depression, urinary retention, nausea and post-operative ileus to name just a few. One surgeon’s patients required significantly less opioids intraoperatively compared to the rest of the surgeons. Further studies might warrant examining this surgeon’s technique or the demographics of his patient population to determine how better pain control and less opioid consumption could be achieved across all joints with all participating surgeons

Surgical management of nonobstructive azoospermia

Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a comprehensive review of surgical sperm retrieval approaches in the patient with NOA emphasizing complications, success rates and outcome optimization, a Medline search was conducted querying surgical approaches used to manage NOA. Four sperm extraction techniques are described including: testicular sperm aspiration, testicular sperm extraction, fine needle aspiration mapping and microdissection testicular sperm extraction. In addition, the roles for pre-extraction varicocelectomy and sperm cryopreservation are discussed. The management of NOA continues to evolve as newer tools become available. Several modalities of sperm acquisition exist. An understanding of their complications and success rates is fundamental to the treatment of NOA

From Low-Distortion Norm Embeddings to Explicit Uncertainty Relations and Efficient Information Locking

The existence of quantum uncertainty relations is the essential reason that some classically impossible cryptographic primitives become possible when quantum communication is allowed. One direct operational manifestation of these uncertainty relations is a purely quantum effect referred to as information locking. A locking scheme can be viewed as a cryptographic protocol in which a uniformly random n-bit message is encoded in a quantum system using a classical key of size much smaller than n. Without the key, no measurement of this quantum state can extract more than a negligible amount of information about the message, in which case the message is said to be "locked". Furthermore, knowing the key, it is possible to recover, that is "unlock", the message. In this paper, we make the following contributions by exploiting a connection between uncertainty relations and low-distortion embeddings of L2 into L1. We introduce the notion of metric uncertainty relations and connect it to low-distortion embeddings of L2 into L1. A metric uncertainty relation also implies an entropic uncertainty relation. We prove that random bases satisfy uncertainty relations with a stronger definition and better parameters than previously known. Our proof is also considerably simpler than earlier proofs. We apply this result to show the existence of locking schemes with key size independent of the message length. We give efficient constructions of metric uncertainty relations. The bases defining these metric uncertainty relations are computable by quantum circuits of almost linear size. This leads to the first explicit construction of a strong information locking scheme. Moreover, we present a locking scheme that is close to being implementable with current technology. We apply our metric uncertainty relations to exhibit communication protocols that perform quantum equality testing.Comment: 60 pages, 5 figures. v4: published versio

Ultrastructural Islet Study of Early Fibrosis in the Ren2 Rat Model of Hypertension Emerging Role of the Islet Pancreatic Pericyte-Stellate Cell

Type 2 diabetes mellitus is a multifactorial disease with polygenic and environmental stressors resulting in multiple metabolic toxicities and islet oxidative stress. We have integrated the role of the islet renin-angiotensin system (RAS) in the pathogenesis of early islet fibrosis utilizing the transgenic (mRen2)27 rodent model of hypertension and tissue RAS overexpression. The Ren2 pancreatic islet tissue was evaluated with transmission electron microscopy to study both early cellular and extracellular matrix remodeling. Major remodeling differences in the Ren2 model were found to be located within the islet exocrine interface, including deposition of early fibrillar-banded collagen (fibrosis) and cellular remodeling of the pericyte suggesting proliferation, migration, hypertrophy and activation as compared to the Sprague Dawley controls.This research was supported by the investigator initiated grants NIH (R01 HL73101-01A1), the Veterans Affairs Merit System (0018) grant and Novartis Pharmaceuticals. Male transgenic Ren2 rats and male Sprague-Dawley controls were kindly provided by Dr. Carlos M.
