Mixed Reality Lab at Mississippi State University Libraries

Virtual and Augmented Realities are advancing technologies that are becoming more popular in gaming and programming communities. However, virtual reality has been in development for decades. As libraries are often at the forefront of offering new and advancing technologies to their communities, virtual and augmented reality programs have become new additions to library services. While gaming is the prominent use of these technologies, virtual and augmented reality affords many educational opportunities. Mississippi State University Libraries have recently added a virtual/augmented reality lab as part of its library program.  相似文献   

Tier-specific evolution of match performance characteristics in the English Premier League: it’s getting tougher at the top

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers.  相似文献

Ocular dominance,reading and spelling: a reassessment of a measure associated with specific reading difficulties     

S. P. Newman  H. Karle  J. F. Wadsworth  R. Archer  R. Hockly  P. Rogers 《Journal of Research in Reading》1985,8(2):127-138

The association of reading disability with perceptuomotor problems has had a chequered history. This study examines the relationship between a new test of ocular dominance and reading and spelling ability in a group of 323 schoolchildren. Similar rates for unfixed ocular dominance were found for poor readers as in comparable studies. The rates of unstable ocular dominance did not differ between those with reading and spelling difficulties and controls. These findings in a ‘blind’ study question the role of this test of eye dominance as a diagnosis of ‘dyslexia’.  相似文献   

Information asymmetry and information sharing   总被引：1，自引：0，他引：1  

Gavin Clarkson  Trond E. Jacobsen  Archer L. Batcheller   《Government Information Quarterly》2007,24(4):827

Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry has been insufficiently studied as a possible cause of underdevelopment and inequality. In response, we develop a typology to classify information asymmetry into two categories, horizontal and vertical, and then identify those information sharing practices that cause the imbalance. To illustrate the negative consequences of information asymmetry and the potential benefits of information sharing, we discuss two examples from the experiences of modern American Indian tribes. First, Indian tribes face horizontal information asymmetry when they attempt to access the capital markets, and second, they face vertical information asymmetry in terms of law enforcement data sharing. This article also describes our ongoing examination of horizontal information sharing among tribes and vertical information sharing between tribes and others sovereigns in the American polity as possible solutions to the problems created by information asymmetry. These strategic responses are embodied in two information systems, the Tribal Financial Information Clearinghouse and an Intergovernmental Tracking System for sharing law enforcement data. We conclude with a discussion of how our typology can be more generally applied to other instances of information asymmetry.  相似文献

Mathematics for teaching and deep subject knowledge: voices of Mathematics Enhancement Course students in England     

Jill Adler  Sarmin Hossain  Mary Stevenson  John Clarke  Rosa Archer  Barry Grantham 《Journal of Mathematics Teacher Education》2014,17(2):129-148

This article reports an investigation into how students of a mathematics course for prospective secondary mathematics teachers in England talk about the notion of ‘understanding mathematics in depth’, which was an explicit goal of the course. We interviewed eighteen students of the course. Through our social practice frame and in the light of a review of the literature on mathematical knowledge for teaching, we describe three themes that weave through the students’ talk: reasoning, connectedness and being mathematical. We argue that these themes illuminate privileged messages in the course, as well as the boundary and relationship between mathematical and pedagogic content knowledge in secondary mathematics teacher education practice.  相似文献

Role of exteroceptive background context in taste-aversion conditioning and extinction     

Trevor Archer  Per-Olow Sjödén  Lars-Göran Nilsson  Ned Carter 《Learning & behavior》1979,7(1):17-22

In two experiments, saccharin (CS) and lithium chloride (US) were paired in a context consisting of specific visual, auditory, tactual, and olfactory cues. The saccharin aversion was then extinguished in a context free from conditioning-context cues. Later, saccharin preference tests were given in the presence and absence of these cues. The results indicated that the background cues of the conditioning trial controlled the amount of saccharin drunk on extinction trials, and, furthermore, that extinction of the taste aversion was context specific; i.e., groups given extinction trials in a different (from conditioning) context retained their saccharin aversion in the conditioning context only. The results indicate an important role played by the exteroceptive context in taste-aversion conditioning.  相似文献   

Exteroceptive cues in taste-aversion learning,no artifact: Reply to Holder     

Per-Olow Sjödén  Trevor Archer 《Learning & behavior》1988,16(2):235-239

Holder (1988) has raised several objections to our work on the role of exteroceptive contextual stimuli in taste-aversion learning by rats. Our main conclusion from that work is that tongue-tactile stimuli from the drinking spout constitute the likely basis for findings of contextual bottle control over learned taste aversions. Holder suggests that our results are confounded by taste cues from the fluid containers. We refute this suggestion by presenting data from two experiments showing contextual bottle control, even though potential taste cues from the drinking bottles were eliminated. We also point to the fact that some of Holder’s criticisms are based on misreadings of our various reports.  相似文献
