Libraries have been the key to preserving culture and historic legacy for centuries. One such treasure cataloged in The Pennsylvania State University (Penn State) Libraries is a collection of over 33,000 Sanborn? Fire Insurance Maps. Originally kept safe in metal drawers, the library has embarked on a journey to digitize this abundance of information, combine it with other media such as photographs, and make it accessible through a web interface. Inspired by these efforts, we accessed this information and took it to the next level. Using state of the art 3D modeling and immersive technologies, we created a historic 3D model and immersive experiences of Penn State, exemplarily for the 1922 campus. The resulting experiences can be accessed through the web but also through head mounted displays (HMDs) and mobile phones in combination with VR viewers such as the Google Cardboard. Additionally, they can be used anywhere in the world or on the campus itself as a way to enable remote and in situ experiences and learning. Immersive experiences let us connect to the past, the present and the future, and as such offer value to digital cultural heritage efforts. 相似文献

Video market entry options available to telephone companies under the Telecommunications Act of 1996 have First Amendment implications that will affect the constitutional value of telephone video. These entry options impose regulatory constraints upon providers and differ in potentials for provider speech, speaker access, and content diversity. The author concludes that the Act's open video system option best advances First Amendment interests in increased diversity of and access to speech. 相似文献

This article provides information on the evaluation of a project between the Australian Museum and the Juvenile Justice department in New South Wales, Australia, where young people who offend of Pacific Islander heritage were introduced to an extensive range of Pacific Islander cultural materials. The key assumption of the project was that young Pacific Islander people who offend struggled with cultural identity issues, and that a meaningful connection with their heritage would improve cultural knowledge and pride—thereby reducing their involvement in crime. However, this assumption was not borne out by the study's results. Firstly, the twenty‐two Pacific Islander young offender study participants were already proud of their heritage, and comfortable in their cultural identities. Secondly, though they enjoyed their visit to the museum, most did not want to visit again, so there was no sustained engagement. Thirdly, the Museum program was not designed as part of a holistic approach with multiple strategies which addressed the complex reasons for youth offending. Despite eight out of the twenty‐two participants reoffending after the Museum visit, there was enough potential for the rehabilitative intervention that the Museum was granted funding to take its program to the community and make it more user‐centered. This, it is hoped, will set it on a path towards more sustained engagement, and the potential for a greater influence on Pacific Islander youth. 相似文献

Attitudes and approaches toward the collection, use, and care of color photographs have evolved enormously since the official arrival of commercially viable color photographic processes in the early twentieth century. This article traces the evolution of collection, exhibition, and preservation practices for works of art in color photography over the last few decades, as represented by one institution, The Metropolitan Museum of Art. 相似文献

Mooses and colleagues suggest that running economy alone does not explain superior distance running performance in elite Kenyan runners. Whilst we agree with the multi-factorial hypothesis for Kenyan running success, we do not believe that running economy can be overlooked to the extent that it was based on this particular study. Based on the methods used and the range of athletes tested, in this response letter we question whether this study provides any basis for downplaying the influence of running economy or suggesting that other factors compensate for it to enable superior performance. 相似文献

Limited recommendations of wheelchair configurations for court sports have been identified in the published literature. To accommodate the wide range of impairments in wheelchair rugby, players are given a point score that reflects their impairment. Players have regularly been grouped as high-, mid-, or low-point players in research, with high-point players having greater levels of muscle function compared with other classifications. This research documented the wheelchair configurations of elite Australian wheelchair rugby players across classification groups. Significant differences (p < 0.05) were found for increased seat height and decreased seat depth for high-point players compared with low- and mid-point groups, respectively. Low-point players displayed reduced wheelchair mass compared with high- and mid-point players, as well as increased frame length. Camber angles showed no significant differences across the classification groups. The incorporation of anthropometric measures, such as the elbow angle at the top dead center, was also investigated. While elbow angle showed no significant differences, seat height-to-total arm length ratio was higher for high-point players. Participants also completed surveys detailing their perception of the effect of altering wheelchair configurations. It is suggested that wheelchair configurations should consider an individual’s anthropometrics, impairment, training history, and court role to promote optimal performance, with predictive modeling having the potential to reduce the associated time and cost. 相似文献

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise. 相似文献
