Southern Arkansas University is a public four-year institution located in Magnolia, Arkansas, in Columbia County, Arkansas, situated less than 20 miles north of the Louisiana state line.Maintaining a 17-1 student to instructor ratio, and boasting a family-like atmosphere, Southern Arkansas University offers programs that are unique for the region, including Game and Animation Design with a computer science concentration, or an arts and design focus. The University also provides an engineering program, the only of its kind in the southern half of the state.In 2002, the University began a major capital campaign, the “Blue and Gold Vision,” to upgrade academic and athletic facilities across the campus. The Blue and Gold Vision aims to raise $102.2 million for improvements to the University through a mix of public and private financing. Through the Blue and Gold Vision several new facilities have been built, including: the Donald W. Reynolds Campus & Community Center, Band Building, Mulerider Stables, University Village, Harton Theatre, Fincher Hall, and the Story Rodeo Arena. Wikipedia.

As one of the few known species in an active phase of intron proliferation, the microcrustacean Daphnia pulex is an especially attractive system for interrogating the gain and loss of introns in natural populations. In this study, we used a comparative populationgenomic approach to identify and characterize 90 recently gained introns in this species. Molecular clock analyses indicate that these introns arose between 3.9 × 105and1.45× 104years ago, with a spike in intron proliferation approximately 5.2 × 104to1.22× 105 years ago. Parallel gains at homologous positions contribute to 47.8% (43/90) of discovered new introns. A disproportionally large number of new introns were found in historically isolated populations in Oregon. Nonetheless, derived, intron-bearing alleles were also identified in a wide range of geographic locations, suggesting intron gain and, to a lesser degree, intron loss are important sources of genetic variation in natural populations of Daphnia. A majority (55/90 or 61.1%) of the identified neointrons have associated internal direct repeats with lengths and compositions that are unlikely to occur by chance, suggesting repeated bouts of staggered double-strand breaks (DSBs) during their evolution. Accordingly, internal, staggered DSBs may contribute to a passive trend toward increased length and sequence diversity in nascent introns. © The Author(s) 2014.

Alzheimer's disease (AD), one of the major causes of disability and mortality in Western societies, is a progressive age-related neurodegenerative disorder. Increasing evidence suggests that the etiology of AD may involve disruptions of zinc (Zn) homeostasis. This review discusses current evidence supporting a potential role of Zn and zinc transporters (ZnTs) in processing of the amyloid beta protein precursor (APP) and amyloid beta (Aβ) peptide generation and aggregation. © 2012 International Union of Biochemistry and Molecular Biology, Inc.

Total JIT (T-JIT) is defined as an integrated supply chain strategy incorporating previously defined elements of JIT-production, JIT-purchasing, JIT-selling, with the addition of an important new element, JIT-information. It would be interesting and informative to discover the extended concept's effect on supply chain competency and organizational performance. Here we examine the impact of a T-JIT strategy within a supply chain context, and analyze a model incorporating T-JIT as the focal construct with supply chain management strategy (SCMS) as an antecedent and supply chain competency (SCC) and organizational performance as consequences. Data from manufacturing managers were collected and the model assessed using a structural equation modeling methodology. Study results indicate significant, positive relationships between a supply chain management strategy and T-JIT, T-JIT and supply chain competency, and supply chain competency and organizational performance. The hypothesized relationship between T-JIT and organizational performance was not supported; however. This research is among the first to examine the impact of a T-JIT strategy within a supply chain context. The results of this study support T-JIT as a viable supply chain strategy that influences overall supply chain competency, contributing to organizational performance. In addition the definition of total system JIT and a scale for its measure is developed. © 2013 Elsevier B.V. Source

Purpose - This study aims to assess the impact of a JIT-selling strategy on organizational structure by generally replicating the previous work of Germain ITet al./IT Design/methodology/approach - In contrast to the sample population of logistics managers surveyed by Germain ITet al./IT this research draws on data from manufacturing executives with marketing responsibilities. More importantly, a major limitation of the earlier research, use of a single-item scale measurement of the JIT-selling construct, is overcome. A structural equation modeling approach was used to assess the impact of JIT-selling on the organizational structure dimensions of integration, performance control, specialization, and decentralization. Findings - Germain ITet al./IT found that JIT-selling impacts performance control, specialization, and scheduling decentralization but not integration. While the results of this study support earlier findings that JIT-selling impacts performance control and specialization, the results alternately find support for a relationship between JIT-selling and integration and refute the previous finding that JIT-selling is related to decentralization. Research limitations/implications - The findings generally support the proposition that adoption of a JIT-selling strategy will result in changes in organizational structure. Practical implications - Manufacturing managers working to strengthen relationships with customers through a JIT-selling approach should prepare for organizational change in terms of increased integration, performance control, and specialization. Originality/value - JIT strategies are being used to strengthen the operations/marketing interface within the manufacturing sector. Specifically, this study assesses the impact of the JIT-selling strategy on organizational structure in an effort to verify the work of Germain ITet al./IT Copyright © 2011 Emerald Group Publishing Limited.

In this paper we investigate the role of spreadsheet self-efficacy, spreadsheet anxiety, and gender in explaining performance in using spreadsheets. Additionally, we compare two learning assessment formats: multiple choice tests and constructed response tests, as applied to spreadsheets. The empirical investigation using data from 217 students indicates the following: (1) spreadsheet self-efficacy was inversely related to spreadsheet anxiety. (2) Female students reported higher levels of spreadsheet anxiety. (3) There was significant difference between the variances of multiple choice test scores and constructed response test scores and (4) Female students performed better than male students in multiple choice test format and were at par with male students in constructed response test format.
