Enhancing Student Learning: An Examination Of The Student Use Of Textbooks In Financial Accounting
Authors: Jones Jefferson P. 
Published: February 2016

As accounting instructors, we provide our students with guidance that will assist them in more effectively and efficiently learning the required material. Often, this guidance includes prescriptive advice on how to properly use their textbook. However, little evidence exists as to whether students actually follow our advice on how to use their textbook. Therefore, when student (and instructor) frustrations arise with regard to class performance, it is unclear whether students are simply not using the textbook effectively or if there are more fundamental problems with the textbook itself. The purpose of this study is to provide evidence as to how students actually use their financial accounting textbooks. Based on instructor and student surveys, the results indicate that students approach textbooks differently from the traditional notion that many instructors encourage. Evidence suggests that students value textbooks, but that they primarily use textbooks as a source of examples and descriptions to help them complete homework. In short, students do not appear to be reading textbooks, but referencing them. The implications of this behavior suggest that textbook authors and publishers need to reconsider textbook design. In addition, instructors, armed with the knowledge of how their students are using the textbook, can better design their course to encourage student success.

Under an NSF REU center grant REU-0755355 entitled “Micro/Nano Assembly Workcell Via Micro Visual Sensing and Haptic Feedback”, Texas A&M University – Corpus Christi and Texas State University – San Marcos collaboratively hosted two groups of 10 students from different backgrounds for 10 weeks each in Summer 2008 and 2009 respectively. The research effort involved is part of an ongoing research program developing novel methods for making automated micromanipulation systems. The twenty students and two teachers were divided into four teams developing interrelated aspects of the project. The first team developed the micro-scale parts, such as gears, for assembly. This required the team to develop techniques for etch and release of three dimensional parts from a silicon substrate. The second team developed the microscopic vision system used for locating and identifying parts on a silicon wafer. The vision system is used to determine the position on the wafer of the parts, their diameter (one of several standard parts), and, utilizing a novel technique developed by the team, the thickness of the parts. The third team developed a robotic platform able to locate any portion of a wafer for manipulation within a three-dimensional space with 10μm accuracy. This mechanism is used to first bring any desired portion of the wafer to the vision system for analysis and also to bring a manipulator to “pick and place” parts using the vision system for feedback. The fourth group developed the micro-manipulator in the form of a “gripper” powered by electro-active polymer. This gripper was capable of accurately and repeatably gripping, lifting, moving, placing, and releasing parts at any point within the workspace. Collectively, the REU project successfully produced a prototype system advancing the state-of-art for an important are of micro-manufacturing while offering a stimulating experience for undergraduate students. Assessment of the student experience showed an increase in the likelihood for these students to pursue engineering careers and to encourage their peers to consider STEM careers.
Linked-Class Problem-Based Learning In Engineering: Method And Evaluation
Authors: Hunt Emily M. , Lockwood-Cooke Pamela , Kelley Judy 
Published: February 2016

Problem-Based Learning (PBL) is a problem-centered teaching method with exciting potential in engineering education for motivating and enhancing student learning. Implementation of PBL in engineering education has the potential to bridge the gap between theory and practice. Two common problems are encountered when attempting to integrate PBL into the undergraduate engineering classroom: 1) the large time requirement to complete a significant, useful problem and 2) the ability to determine its impact on students. Engineering, mathematics, and science professors at West Texas A&M University (WTAMU) have overcome the large time commitment associated with implementation of PBL in a single course by integrating small components of the larger project into each of their classes and then linking these components with a culminating experience for all the classes. Most of the engineering students were concurrently enrolled in the engineering, mathematics, and science classes and were therefore participating in all activities related to the project. This linked-class PBL experience addressed course concepts, reinforced connections among the courses, and provided real-world applications for the students. Students viewed the experience as beneficial, increasing their understanding of content and applications in each discipline. This paper provides details about implementation and evaluation of one PBL project and how difficulties in evaluation of the linked-class PBL experiences are being addressed.
Alternative Pathways To Engineering Success –Using Academic And Social Integration To Understand Two-Year Engineering Student Success

Published: February 2016

The need for educating engineers in the United States continues as the projected demand is still rising as the number of high school seniors planning to enter engineering careers has remained relatively stable (Sargent, 2014). Additionally, figures show that attrition rates in undergraduate engineering continue to be an area of concern, (Sargent, 2014; Gibbons, 2005; NSF, 2004). Given the projected increased demand for engineers, the engineering education community must explore a variety of pathways for engineering students to be successful. Organizations such as National Science Foundation (Laanan, Jackson, Darrow, 2010) have noted that beginning engineering study at a two-year campus and then transferring to an engineering bachelor’s degree-granting institution is an important path and source for additional engineering students. Although some have explored the logistical issues and curricular design components of two-year campuses that enables engineering students to complete their bachelor degrees elsewhere, there is very little that explores the non-curricular factors on these campuses that help such students successfully progress (Laanan, et al., 2010). Using Tinto’s theory of integration (1975, 1993), this study examines the relationship between student entry characteristics and measures of social and academic integration to engineering learning outcomes. Understanding how integration factors on two-year campuses impact engineering student success can be used to inform the design of curricular and campus-based experiences that support the success of engineering students on two-year campuses. Results indicate the social and academic integration factors significantly predict engineering students’ learning outcomes, especially their commitment to engineering studies.

Published: February 2016

Recognized as one of the central figures of the Law & Society and as one of the first editors of the Law & Society Review, Marc Galanter is the author of pioneer and internationally recognized studies on the legal system and patterns of litigation (including "Why the haves come out ahead: Speculations on the Limits of Legal Change", one of the most cited articles in legal literature), lawyers and legal culture, legal institutions and informal regulation, among others. In this interview, Galanter speaks mostly about his academic and professional trajectory, a narrative that is intertwined with the history of tha Law & Society movement itself and with some of the most important developments in American academia since the 60s to the present day. The author also talks about the growth of law firms (described in Tournament of Lawyers) and cultural perceptions currently surrounding lawyers and the legal profession. He discusses the importance of the studies he developed in India for his work, including the famous "Why the haves come out ahead", a piece that is still relevant in the current context.

Study of Thermal Variations in Wells During Carbon Dioxide Injection
Authors: Lund Halvor , Torsæter Malin , Munkejord Svend Tollak 
Published: February 2016

Summary
Carbon dioxide (CO2) can be injected into the subsurface to achieve enhanced oil recovery (EOR), possibly with geological CO2 storage. This procedure brings about a set of unique challenges with respect to well construction, operation, and remediation. As compared with normal production, CO2 injection imposes lower temperatures and stronger temperature variations on wells. This is especially prevalent if the injection is not continuous. Downhole-temperature variations will result in expansion or contraction of casings and well-barrier materials, which can cause them to crack or debond at interfaces. To avoid leakage paths through wells, it is therefore important to understand within which temperature intervals it is safe to operate.
In the present paper, we describe a heat-conduction model for calculating heat transfer from the well to the casing, annular seal, and rock formation. These materials have dissimilar thermal properties, and will behave differently with respect to downhole-temperature variations. The model is discretized by use of a finite-volume method developed especially for accurate calculation of heat conducted radially in a well. This allows us to predict temperatures and temperature variations at various locations in and around a given well during CO2 injection.
To validate the numerical model, we compare our simulation results with the time-varying temperatures measured in our laboratory. Good agreement is found between the numerical predictions and the measured data. Simulation results are presented for different combinations of formations and well-barrier materials (cement and alternative types of annular sealants) to display their effect on the well temperature. It is found that, by replacing cement with an annular sealant material with higher thermal conductivity, the temperature difference across the seal can be significantly reduced. A high-conductivity formation such as halite/rock salt can also reduce thermal gradients in the well materials.

Abstract
OBJECTIVE To compare efficacy between cyclosporine and prednisone for treatment of primary immune-mediated polyarthritis (IMPA) in dogs.
DESIGN Randomized controlled clinical trial.
ANIMALS 20 client-owned dogs with primary IMPA.
PROCEDURES Dogs were randomly assigned to receive prednisone (starting at 1 mg/kg [0.45 mg/lb], PO, q 12 h; n = 10) or cyclosporine (5 mg/kg [2.3 mg/lb], PO, q 12 h; 10) for 90 days. Cyclosporine-treated dogs also received carprofen, tramadol, or both for the first 7 days for analgesia. Data collection, physical examination, and cytologic analysis of synovial fluid samples were performed on days 0, 14, 45, and 90. Trough whole blood cyclosporine concentrations were determined on days 7 to 17 for cyclosporine-treated dogs. Treatment failure was defined as lack of clinical improvement by day 14, lack of cytologic improvement by day 45, or need to change treatment because of adverse effects.
RESULTS Treatment was successful for 7 prednisone-treated dogs and 7 cyclosporine-treated dogs. Absence of synovial fluid cytologic abnormalities on day 45 was identified for 5 prednisone-treated dogs and 8 cyclosporine-treated dogs. Prednisone-treated dogs were more likely to develop polyuria, polydipsia, and polyphagia than were cyclosporine-treated dogs. Opportunistic infections (ie, demodicosis or Erysipelothrix bacteremia) were identified in 2 cyclosporine-treated dogs and 0 prednisone-treated dogs, and diarrhea developed in 1 cyclosporine-treated dog, requiring treatment discontinuation.
CONCLUSIONS AND CLINICAL RELEVANCE Although the number of dogs evaluated was small, limiting generalizability, results of this study suggested that cyclosporine offers promise as a suitable alternative to prednisone for treatment of IMPA in dogs.

Abstract
CASE DESCRIPTION A 5-year-old 35.8-kg (78.8-lb) neutered male Labrador Retriever was evaluated for chronic nasal discharge associated with a fungal infection. The dog had previously been prescribed antimicrobials and antifungal treatment, but owner compliance was lacking.
CLINICAL FINDINGS Bilateral mucopurulent nasal discharge, mild ulceration of the left nasal commissure, and hyperkeratosis of the dorsal nasal planum were present. Computed tomography revealed destruction of the intranasal structures, focal lysis of the cribriform plate, and invasion of a soft-tissue mass into the frontal cortex. Rhinoscopy revealed a large pale mass in the caudal aspect of the right nasal passage; a biopsy sample was consistent with Aspergillus sp on histologic evaluation.
TREATMENT AND OUTCOME Initial treatment included medical management with an antifungal agent. Approximately 3 months later, a large fungal granuloma in the right frontal sinus was removed and debridement was performed via dorsal rhinotomy. One month after surgery, the dog was evaluated for signs of cervical pain and altered mentation. An MRI and CSF analysis were performed; diagnoses of ventricular pneumocephalus, subarachnoid pneumorrhachis, and meningoencephalitis were made. Management included oxygen therapy and administration of antimicrobials, analgesics, and antifungal medications. On follow-up 9 months after initial evaluation, neurologic deficits were reportedly resolved, and the dog was doing well.
CONCLUSIONS AND CLINICAL RELEVANCE This report emphasizes the importance of prompt, appropriate treatment of fungal rhinitis in dogs. Although rare, pneumocephalus and pneumorrhachis should be included as differential diagnoses for neurologic signs following treatment for this condition. In this dog, the complications were not considered severe and improved over time with supportive care.
Identification of Metastatic Lesions in a Patient With Low Back Pain Following a Motor Vehicle Collision
Authors: Plass Lindsey M. , McGee Terrence G. , Elliott James M. 
Published: February 2016

A 58-year-old man was referred to physical therapy with a primary complaint of intermittent low back pain (LBP) 2 weeks after being in a motor vehicle collision. The absence of red flags justified the initiation of treatment, but when symptoms of unrelenting LBP emerged, he was referred to his primary care physician with a request for further medical workup. Before further imaging work-up was performed, the patient presented to the emergency room with a urinary complaint; this, in combination with unrelenting LBP, prompted further imaging follow-up. Lumbar/thoracic spine magnetic resonance imaging revealed multiple compression fractures and diffuse bone marrow heterogeneity consistent with a malignant infiltrative marrow process. The patient underwent additional laboratory testing and a bone marrow aspirate and biopsy that confirmed the diagnosis of multiple myeloma.

Published: February 2016

Abstract
After polymer flooding in Daqing Oil Field, the injection pressure in the flooded areas has increased. The injection pressure of one third of the polymer-injection wells is near to its fracturing pressure, and many polymer injection wells have to lower its injection rate. Since the effective period of fracturing in polymer injection wells is less than 3 months, a new polymer injection well stimulation technology was in great need to be developed.
The system does not need alkali, and under formation conditions, the interfacial tension remains ultra-low for at least 28 days. A series of lab tests shows that to first remove the polymer adsorbed on the rock, a slug containing an oxidant needs to be injected before the surfactant slug. The surfactant slug lowers the residual oil concentration, increases the relative permeability to water and adsorbs on the rock near the well bore, preventing polymer to adsorb on the rock in the subsequent stage of polymer flooding. Lab tests shows that adopting a flooding process of subsequently injecting an oxidant slug, then a surfactant slug and last followed by polymer flooding obtains the best results (the permeability to polymer fluid is increased about 120%).

Introduction
At present, the starting pressure (e.g., the pressure at which water starts to be injected into the well) of polymer-injection wells is commonly high and injection rate is relative insufficient in Daqing Oil Field. The high starting pressure and injection pressure of the polymer injection wells greatly influence the development results of the oil field, these are mainly reflected in the following aspects:The starting pressure is too high so that an effective pressure differential cannot be set up between production and injection wells, resulting in poor developing result.The high injection pressure causes an increase in the number of casing damage wells.The injection pressure is too high; therefore the injection solution cannot advance evenly into the wells.In order to maintain the injection rate of medium and low permeability layers developed by polymer flooding, the well spacing needs to be reduced and the development cost is increased.
Therefore, it is very important to study technology that can effectively reduce the starting pressure and injection pressure of polymer-injection wells.
GTL Plus Power Generation: The Optimal Alternative for Natural Gas Exploitation in Nigeria
Authors: Adegoke Adesola Ayodeji , Barrufet Maria A. , Ehlig-Economides Christine A. 
Published: February 2016

Abstract
Nigeria has an estimated 187 trillion cubic feet (Tcf) of proven natural gas reserves, which is about 4% of the world proven reserves. About 60% of this reserve is associated gas and over 50% is either being flared or re-injected for enhanced oil recovery. The government just introduced a policy to stop gas flaring by 2008, hence energy companies have to develop new strategies of utilizing the stranded gas reserves especially the associated gas. Liquefied Natural Gas (LNG) is the country's cutting-edge technology in the exploitation of stranded gas reserves. With a projected increase in world market share to 13%; the country ranks as one of the highest producers of LNG in the world. However, while LNG accounts for 27% of all traded natural gas the hydrocarbons used for LNG are dwarfed by the size of liquid middle distillates such as diesel and naptha. Furthermore, LNG as traded today is strongly driven by long-term and high risk contractual agreements.
A re-visited way for natural gas exploitation is the Gas to Liquids (GTL) technology, with most end products being useful in transportation fuels and base chemical feedstock. An often overlooked issue, which could be decisive in Nigeria, is the use of GTL ancillary products with no commercial value. The underlying objective of this study is to build a business case for GTL as an alternative marketing strategy to LNG for stranded gas reserves in Nigeria, with the utilization of by-product streams for commercial power generation.
This analysis will present a robust and economic solution to natural gas exploitation in terms of the technological and environmental factors scalable to supply and demand constraints. Justifying the technology and economics involved in the utilization of the by-product streams for commercial power generation may possibly increase the net revenue and profitability of the GTL projects. This technology may be transferable to other GTL projects in the world wherever there is a market for power generation.

Introduction
The World Bank estimates Nigeria alone accounts for 12.5% of the world's annual gas flared though the Nigerian government has enacted a policy of "Zero-Gas Flare" by 2008. This translates to about 800 Bcf of natural gas flared annually. Hence, energy companies have to develop strategies to utilize the "stranded" gas produced.
