A sewer system is a principal element of infrastructure in modern cities, accounting for massive amounts of public investments. Corrosion of manholes in the sewer system is a global issue, and millions of dollars are being spent on the maintenance, restoration, and replacement of deteriorated sewer networks. Concrete manholes in the sewer system are deteriorating due to the attack of sulfuric acid produced by microorganisms in a process termed microbial induced concrete corrosion (MICC), which reduces the lifespan of concrete sewer elements. The objective of this paper is to investigate the correlation between the gas- and liquid-phase sewer environmental factors and hydrogen sulfide concentration in the gas phase. The production, emission, and build-up of hydrogen sulfide gas in manholes is identified as a major cause of MICC in manhole shafts. The field study was conducted in more than 200 manholes in the City of Arlington (Texas, US). The data was collected every minute for 48 h to understand the trends of liquid- and gas-phase parameters such as hydrogen sulfide (H2S concentration), liquid and gas temperature, pH, DO, and relative humidity. The study also examines how gas-phase H2S concentrations vary with season; manhole design, including manholes' depth, slope, and presence of drop; and sewer flow conditions such as velocity and turbulence. Although no strong linear correlation was found between liquid-/gas-phase parameters, the manhole categories were found to play a significant role in H2S generation. The manholes with hydraulic jump generated the highest average H2S concentrations, followed by manholes with drops. High turbulence zones were observed in manholes of both categories, leading to H2S stripping from liquid to gas phase. The highest H2S concentration was recorded in summer, suggesting that higher liquid temperature resulted in increased bacterial activity, which generated greater liquid-phase sulfide. Greater Henry's law constants in summer, due to high temperatures, would have favored transfer of liquid-phase sulfide to the gas phase. [ABSTRACT FROM AUTHOR]

In November 1966, at the Southern Historical Association (SHA) convention in Memphis, Tennessee, some 20 participants organized the Association of the Southern Labor Historians whose purpose was to promote the Southern labor history by encouraging the collection of labor records in various states and tile presentation of scholarly labor papers at annual meetings concurrent with SHA. The author and his friends inquired that no university in the Southwest was soliciting labor records. Professor Dick Shuttee, a labor economist at the University of Texas, Arlington, (UTA) was quite enthusiastic about the idea of an archives. With the permission of the History Department of UTA, the author and his colleagues started the Archives Project with a half-summer salary. About three dozen Texas labor newspapers and newsletters have been collected or have been purchased from other archives' microfilmed holdings. The Texas Labor Archives of UTA is currently the only depository in the Southwest that actively seeks union records.

Purpose – The purpose of this paper is to define and describe informal screencasting (i.e. capturing your actions on a computer screen with the goal of showing others how to accomplish tasks on a website or in a given software environment). Customer-satisfaction survey results from 103 faculty, staff, and students are presented. Design/methodology/approach – An online survey revealing customer satisfaction with informal screencasts was made available in Spring 2010 to faculty, staff, and students of a mid-sized public university in Arlington, Texas, USA. Results are compiled, analyzed, and presented here. Findings – Most participants' reactions to the librarian's informal screencasts were positive or quite positive, but many participants still noted that they would prefer to receive e-mail instructions in answer to their questions. Research limitations/implications – The survey was not distributed to a representative sample of the population; instead, the author solicited participants via e-mail, so the participant pool was a convenience sample, which could introduce bias in the results. Originality/value – This survey is the first to assess academic library customers' attitudes toward informal screencasting as an instructional tool, as far as the author has been able to determine after an extensive literature search.

Abstract: This paper proposes a reformulation of count models as a special case of generalized ordered-response models in which a single latent continuous variable is partitioned into mutually exclusive intervals. Using this equivalent latent variable-based generalized ordered response framework for count data models, we are then able to gainfully and efficiently introduce temporal and spatial dependencies through the latent continuous variables. Our formulation also allows handling excess zeros in correlated count data, a phenomenon that is commonly found in practice. A composite marginal likelihood inference approach is used to estimate model parameters. The modeling framework is applied to predict crash frequency at urban intersections in Arlington, Texas. The sample is drawn from the Texas Department of Transportation (TxDOT) crash incident files between 2003 and 2009, resulting in 1190 intersection-year observations. The results reveal the presence of intersection-specific time-invariant unobserved components influencing crash propensity and a spatial lag structure to characterize spatial dependence. Roadway configuration, approach roadway functional types, traffic control type, total daily entering traffic volumes and the split of volumes between approaches are all important variables in determining crash frequency at intersections.

Nurses comprise the largest group of health-care providers and should be key partners for any disaster response in their community. An often untapped resource in many communities is the contingent of nurse faculty, staff and students in schools of nursing across the country. In an effort to provide guidance on how schools and colleges of nursing link with their community and provide real-world experience for students, the present paper: (i) outlines how a Memorandum of Cooperation between the City of Austin and the University of Texas at Austin was created; and (ii) describes an example of how a school of nursing could become organized to respond to a community's call for help.

In this paper, we reexamine the issue of whether corporate relocation assistance programs for transferred employees significantly affect sale prices of single-family homes. We estimate a hedonic price equation that includes physical housing characteristics, location factors, occupancy status, and type of seller for a sample of 2,441 transactions. Seller types include (a) transferred employees who were given direct relocation assistance, (b) transferred employees who were not given direct relocation assistance, and (c) sellers who were not facing an employment transfer. After controlling for vacancy and tenant occupancy, we find that houses sold by transferred employees who receive direct relocation assistance exhibit no significant price differential, but that houses sold by transferred employees who do not receive direct relocation assistance sell at a discount of approximately 3%.

The transition of the dental histology course at the University of Texas Health Science Center at San Antonio Dental School was completed gradually over a five-year period. A pilot project was initially conducted to study the feasibility of integrating virtual microscopy into a traditional light microscopic lecture and laboratory course. Because of the difficulty of procuring quality calcified and decalcified sections of teeth, slides from the student loan collection in the oral histology block of the course were outsourced for conversion to digital images and placed on DVDs along with a slide viewer. The slide viewer mimicked the light microscope, allowing horizontal and vertical movement and changing of magnification, and, in addition, a feature to capture static images. In a survey, students rated the ease of use of the software, quality of the images, maneuverability of the images, and questions regarding use of the software, effective use of laboratory, and faculty time. Because of the positive support from the students, our entire student loan collection of 153 glass slides was subsequently converted to virtual images and distributed on an Apricorn pocket external hard drive. Students were asked to assess the virtual microscope over a four-year period. As a result of the surveys, light microscopes have been totally eliminated, and microscope exams have been replaced with project slide examinations. In the future, we plan to expand our virtual slides and incorporate computer testing. [ABSTRACT FROM AUTHOR]

This article describes a model, benefits, and outcomes of a coaching and support group for managers. Professionals in the University of Texas at Austin Employee Assistance Program have created manager groups to support and coach managers in areas of skill development, including interpersonal challenges and communication, while providing a confidential forum for professional discussion. It is basic practice for EAPs to provide support to employees dealing with personal problems and one-on-one consultation for managers about an employee; however, few, if any, EAPs provide group coaching for managers in their roles as leaders. By facilitating manager groups EAPs can help reduce managers' stress and build their supportive and professional networks while helping to develop managers' communication and "soft skills." A model is presented to demonstrate the format of the manager groups facilitated at the University of Texas at Austin. [ABSTRACT FROM AUTHOR]

The University of Texas at Arlington's Library began using an online chat reference in 2002. The service, called Collaborative Digital Reference Service, later became "Ask a Librarian." Slightly over one year later, the library joined the University of Texas System's "Ask a Librarian" service. Both services are powered by software suite called QuestionPoint. In May 2003 and May 2004, the library's reference staff shared their views towards this new reference tool by completing a questionnaire. Statistics and staff members' responses are analyzed in this study. [ABSTRACT FROM AUTHOR]

A series of resonant column tests was conducted on chemically stabilized specimens of sulfate-rich expansive clay from southeast Arlington, Tex. Specimens were tested for different stabilizer types, stabilizer dosages, compaction moisture contents, and confining pressures. Three chemical stabilization methods were used: sulfate resistant type V cement, low calcium class F fly ash, and lime mixed with polypropylene fibers. Results in the small-shear strain amplitude range (<0.0001%) were analyzed to assess the influence of compaction moisture content and confining pressure on the linear shear modulus G[sub max] and material damping D[sub min] of stabilized soil. Tests were also conducted at small- to mid-shear strain amplitude levels (0.0001–0.01%) to assess the threshold strain limit γ[sub th] for each treatment method, and to study the effects of torsional shearing on the rate of degradation of normalized modulus G/G[sub max] of treated soil. A 10%-by-weight dosage of sulfate resistant type V cement was found to give the highest modulus and lowest damping when compacted at 95% of maximum dry unit weight γ[sub d-max] on the wet side of Proctor optimum.

The article presents information related to the field of accounting. In December, 1947, the Association of University Teachers of Accounting was formed. The Secretary advises that, until this group was formed, there existed in Great Britain no organization which was the counterpart of the American Accounting Association. The list of members is very small, by comparison, about thirty in number, but nevertheless includes virtually all university teachers of accounting in England and Scotland. At a recent meeting in Fort Worth of the Texas Association of University Instructors in Accounting, the following officers were elected President, O.J. Curry, North Texas State College; Vice-President, Charles Zlatkovitch, University of Texas; Secretary-Treasurer, Zeb B. Freeeman, Southern Methodist University. D. M. Beights served on the summer school staff at University of North Carolina, conducting a special course under joint sponsorship of the University and the North Carolina Society of Certified Public Accountants.
