Volunteer Motivations at the 2012 Super Bowl

Purpose – The purpose of this paper is to examine mega-event volunteers’ motivations and their impact on volunteer satisfaction. Additionally, this study investigated motivational differences between volunteers based upon four demographic variables: age, gender, educational level, and income. Design/methodology/approach – A modified version of the Volunteer Motivations Scale for International Sporting Events (Bang and Chelladurai, 2009) was administered to 8,000 Super Bowl volunteers via Survey Monkey with the permission of the Indiana Sports Corporation. In all, 24 percent (n=1,928) of the volunteers completed the survey. Exploratory factor analysis was used to reduce the survey questions into a smaller number factors. Multivariate analysis of variance was utilized to compare differences in the four demographic variables on the factors. Multiple regression was used to predict satisfaction on the basis of the four factors. Findings – Volunteers were motivated by four factors: Community Support, Love of Sports, Personal Growth, and Career Development. These four factors all significantly predicted satisfaction with the volunteer experience. The overall MANOVA was significant and revealed that ten of 16 group comparisons possessed significant differences. Females rated Community higher than males, while males rated Love of Sports higher than females. Older volunteers and those with higher household incomes were motivated more by Community Support, while younger volunteers and those with lower incomes were motivated by Career Development. Likewise, less educated volunteers placed a higher value on Career motivations than more educated volunteers who placed a high value on Personal Growth. Research limitations/implications – Dissatisfied volunteers may have chosen to not participate in the study. Follow-up interviews with dissatisfied volunteers might provide insight for event organizers that would shed light on factors that influence retention and recidivism. Practical implications – The findings of this study suggest that mega sport volunteer managers should recognize that motivational differences among volunteers do exist and utilize this information for creating recruitment materials targeted to specific groups. Then volunteers can be assigned to tasks that tap into their desire, thus enhancing potential volunteer satisfaction and their return as a volunteer at future events. Originality/value – This study was conducted in the context of America’s largest mega event in a city that hosted the event for the first time. In addition to collecting one of the largest number of responses for volunteers at mega-sporting events, the development of the Community Support factor was unique within the context of this study. The Community Support factor was rated as the most important by volunteers and tied to other questions such as wanting to help make the event a success, helping others, and creating a better society. This indicates that volunteers had pride in their community and wanted to help the event be successful by helping the city’s visitors

Environmental Impacts from Pesticide Use: A Case Study of Soil Fumigation in Florida Tomato Production

The search for alternative fumigants has been ongoing since the 1992 Parties of the Montreal Protocol classified methyl bromide as a Class I controlled substance with an ozone depletion potential (ODP) of 0.7 and destined it for phase-out. This paper focuses on the hazards from fumigants proposed as alternatives for pre-plant soil fumigation in tomato production. We use the Environmental Impact Quotient (EIQ) developed by Kovach et al. to estimate the hazards from methyl bromide and the proposed alternative fumigants to workers, consumers, beneficial arthropods, birds, fish, and bees. Our findings indicate that iodomethane 98/2 has the lowest EIQ index value and field use rating, and is the alternative with the lowest relative risk. Among environmental categories, workers and beneficial arthropods experience the highest relative risks from the proposed tomato fumigants, and fish and consumers the least risks

Final Design and On-Sky Testing of the iLocater SX Acquisition Camera: Broadband Single-Mode Fiber Coupling

Enabling efficient injection of light into single-mode fibers (SMFs) is a key requirement in realizing diffraction-limited astronomical spectroscopy on ground-based telescopes. SMF-fed spectrographs, facilitated by the use of adaptive optics (AO), offer distinct advantages over comparable seeing-limited designs, including higher spectral resolution within a compact and stable instrument volume, and a telescope independent spectrograph design. iLocater is an extremely precise radial velocity (EPRV) spectrograph being built for the Large Binocular Telescope (LBT). We have designed and built the front-end fiber injection system, or acquisition camera, for the SX (left) primary mirror of the LBT. The instrument was installed in 2019 and underwent on-sky commissioning and performance assessment. In this paper, we present the instrument requirements, acquisition camera design, as well as results from first-light measurements. Broadband single-mode fiber coupling in excess of 35% (absolute) in the near-infrared (0.97-1.31{\mu}m) was achieved across a range of target magnitudes, spectral types, and observing conditions. Successful demonstration of on-sky performance represents both a major milestone in the development of iLocater and in making efficient ground-based SMF-fed astronomical instruments a reality.Comment: 18 pages, 17 figures.

Expanding the phenotype: Four new cases and hope for treatment in Bachmann-Bupp syndrome

Bachmann-Bupp syndrome (BABS) is a rare syndrome caused by gain-of-function variants in the C-terminus of ornithine decarboxylase (ODC coded by the ODC1 gene). BABS is characterized by developmental delay, macrocephaly, macrosomia, and an unusual pattern of non-congenital alopecia. Recent diagnosis of four more BABS patients provides further characterization of the phenotype of this syndrome including late-onset seizures in the oldest reported patient at 23 years of age, representing the first report for this phenotype in BABS. Neuroimaging abnormalities continue to be an inconsistent feature of the syndrome. This may be related to the yet unknown impact of ODC/polyamine dysregulation on the developing brain in this syndrome. Variants continue to cluster, providing support to a universal biochemical mechanism related to elevated ODC protein, enzyme activity, and abnormalities in polyamine levels. Recommendations for medical management can now be suggested as well as the potential for targeted molecular or metabolic testing when encountering this unique phenotype. The natural history of this syndrome will evolve with difluoromethylornithine (DFMO) therapy and raise new questions for further study and understanding

Evaluation of a Manual Wheelchair Interface to Computer Games

The sedentary lifestyle of many people with spinal cord injury (SCI) has lead to cardiovascular diseases being a major health concern. A suitable exercise program may help improve the SCI individual's cardiovascular fitness level. GAMEWheels is an in terface between a custom wheelchair roller system and a computer that enables an individual to control computer video games by driving his or her wheelchair. The purpose of Phase 1 was to evaluate the design of the GAMEwhccls system and to determine the type of computer video game that is likely to motivate wheelchair users to exercise. Phase 2 included physiologic testing of wheelchair users and the GAMEWheels system to investigate whether the system elicits an exercise training re sponse. Thirty-five subjects were recruited to evaluate the GAMEWheels by playing three commercial computer games (Phase 1) and to identify the computer game that they would prefer to use when exercising. The feedback from Phase 1 was used with test subjects to verify that the GAMEWheels system elicits an exercise training effect (Phase 2). Phase 2 included 10 subjects using the GAMEWheels system to play Need for Speed II. During game play, physiologic data were collected and the subjects' oxy gen consumption and heart rate were analyzed. Analysis showed that the GAMEWheels system induced nine subjects to reach their training zone, defined as 50% and 60% of their maximum oxygen consumption and heart rate, respectively. This study demon strates that the GAMEWheels system elicits an exercise training response. © 2000, Sage Publications. All rights reserved

Waiting to Vote in the 2016 Presidential Election: Evidence from a Multi-county Study

This paper is the result of a nationwide study of polling place dynamics in the 2016 presidential election. Research teams, recruited from local colleges and universities and located in twenty-eight election jurisdictions across the United States, observed and timed voters as they entered the queue at their respective polling places and then voted. We report results about four specific polling place operations and practices: the length of the check-in line, the number of voters leaving the check-in line once they have joined it, the time for a voter to check in to vote (i.e., verify voter’s identification and obtain a ballot), and the time to complete a ballot. Long lines, waiting times, and times to vote are closely related to time of day (mornings are busiest for polling places). We found the recent adoption of photographic voter identification (ID) requirements to have a disparate effect on the time to check in among white and nonwhite polling places. In majority-white polling places, scanning a voter’s driver’s license speeds up the check-in process. In majority nonwhite polling locations, the effect of strict voter ID requirements increases time to check in, albeit modestly
