APPROACH RUN VELOCITIES OF FEMALE POLE VAULTERS
INTRODUCTION Running speed is an important determinant of success in many sports. The approach run velocity of a pole vaulter is responsible for most of the vaulter's kinetic energy at the instant of take off. If the vault is well executed, this kinetic energy is transformed to potential energy and the vault is successful. For male pole vaulters, a strong relationship has been established between crossbar height cleared and approach run velocity (McGinnis, 1995). The purpose of this study was to determine if the same relationship exists for women pole vaulters. METHODS Approach run velocities were measured for 25 different women pole vaulters competing at three different competitions in 1995 and 1996. A videocamera operated at 60 Hz recorded the approach runs and vaults by each athlete at each competition. A 200 Hz videocamera was also used at one competition. The camera(s) were panned and recorded primarily sagittal views of the approach runs and vaults. Marks were placed on either side of the runway at 4 and 9 m from the back of the vaulting box. The time it took each vaulter to pass between the 9 and 4 m marks was determined by counting video fields. Average velocity for this 5 m interval was then computed from the time. RESULTS The highest successful vault by each vaulter was selected for analysis. These vaults had a mean height of 3.38 m (s.d.= 0.30 m). The lowest height was 3.01 m and the highest was 4.20 m. The vaults had a mean approach run velocity of 7.33 m/s (s.d.= 0.49 mfs). The slowest velocity was 6.25 m/s and the fastest was 8.45 mls. The correlation coefficient between crossbar height and approach run velocity was 0.85 (p< 0.01). CONCLUSIONS The velocity of the approach run is significantly related to the crossbar height that a woman pole vaulter can clear. Analysis of similar data collected for 65 elite male men yielded a correlation coefficient of 0.73 (p< 0.01) between crossbar height and approach run velocity. The stronger relationship for the women indicates that the pole vaulting potential of a woman is more dependent upon approach run speed than that of a man. Since this is a new event for women, their techniques on the pole are not as well developed. The heights they clear are primarily determined by their approach run velocities. Men on the other hand, have more well developed techniques on the pole. The heights they clear are determined by their techniques as well as their approach run velocities.

Ophthalmic Nursing Education: The Key to Unlocking Patient Access to Retina Services
Background: Ophthalmology, the medical field dedicated to the human eye and visual system infrequently uses nurses due to a lack of nursing knowledge about ophthalmology.
Local Problem: An ophthalmic microsystem in the Northeastern United States is experiencing increased demand for services and decreased access to their retina section. The microsystem does not utilize nurses in the clinic because of education and training barriers. The specific aim of this quality improvement (QI) project is to increase nursing knowledge about ophthalmology from baseline to an overall passing score of 80%.
Methods: This QI project sought to see if registered nurses could improve their knowledge of ophthalmology over four weeks with asynchronous, virtual learning modules derived from texts provided by the American Society of Ophthalmic Registered Nurses. Participants completed learning modules about anatomy and physiology of the eye, ophthalmic assessment, and ocular manifestations of systemic illnesses.
Results: Eleven volunteers completed all aspects of this QI project, including an assessment to set a baseline pre-intervention score, with a mean score of 42.54 out of 100 (SD=7.1, Range=0-100). They also took a post-intervention assessment, with a mean score of 77.81 out of 100 (SD= 13.1, Range = 0-100). This QI project found that the mean test score change was statistically significant (P\u3c0.05).
Conclusions: Asynchronous virtual learning has the potential to improve ophthalmic nursing education. The utilization of this modality to educate nurses as a member of the ophthalmic services team is a viable option to possibly alleviate constraints on patient access to retinal services

Depending on Sex? Tongue, sieve, and ladle shaped pendants from late Iron Age Gotland
Artifacts of female dress such as brooches and pendants have long been objects of interest to scholars of late Iron Age /early medieval Scandinavia. They figure in dating and tracing stylistic developments, and their presence is often (controversially) used to help assign gender to burials. There are three types of pendants which constitute a type of feminine adornment unique to Viking Age Gotland: the so-called tongue, sieve, and ladle pendants. The purpose of this paper is to examine these pendant types and the possible symbolic and magical functions behind their forms and manner of use, and how these functions intersected with the ideologies mapped onto female bodies in Old Norse culture(s). The pendants’ appearance as fixed and incomplete sets is analyzed, and the designs of the “tongue”, “sieve” and “ladle” are located within the wider field of Iron Age iconography - particularly in association with the depiction of idealized gender roles. In conclusion a hypothesis as to why these particular amulets were used exclusively by wealthy Viking women is presented; that the tongue, sieve, and ladle pendants signaled and were involved in the construction of a particular type of elite female identity linked to specifically feminine forms of embodied power and prestige within late Iron Age society
Formation of Porous Silicon through the nanosized Pores of an Anodized Alumina Template
This letter demonstrates the ability to fabricate porous silicon through the nanoscale pores of an anodized alumina template formed on a silicon substrate. The alumina template acts as a protective coating on the porous silicon surface increasing its mechanical integrity, thus eliminating the need for delicate handling that is usually required for this material system. The optical properties of the porous silicon formed through the template show characteristics similar to that of normally formed porous silicon. In addition, the porous siliconoptical properties show very little degradation with time; the alumina coating is believed to contribute to this improved stability. The results are significant and can increase the likelihood of commercial applications of this material
ACE! How the Waste Management Phoenix Open Rose from the Ash Heap to become a Sponsorship Exemplar
Waste Management leverages the PGA TOUR’s so-called “People’s Open” in a manner that is unparalleled in the sport industry. The Waste Management Phoenix Open (WMPO) is not only a zero-waste event but also utilizes activation tactics that maximize this value proposition for consumers through sponsored activities that engage fans of all ages, backgrounds, and motivations. After an extensive analysis of the event and what makes it distinct, we propose a framework that we term ACE (Activation optimization, Cohesive value propositions, and Experientially focused programs), which can serve as a three-pronged test that event/property owners and sponsors alike can use to achieve desired results
