Paper Session I-B - Integrating Scientific Payloads in a Commercial Launch Market

Scientific and research payloads are fundamentally different from commercial satellites. This paper presents an integration model to accommodate the special needs of R&D, science, and first time payloads in a launch market which is being developed mostly for commercial communications satellites. The model is supported by actual examples of process changes implemented in the Space Shuttle program

Paper Session III-C - Possible Metrics to Determine the Impact of the SEARCH Program on Brevard County Schools

The paper reports on attempts to measure the effects of a mentoring program called Science, Engineering and Research Help (SEARCH). The paper analyzes the process, reviews the current metrics, and.suggests future possible measures

The Economic Case for a Pandemic Fund

The rapid urban spread of Ebola virus in West Africa in 2014 and consequent breakdown of control measures led to a significant economic impact as well as the burden on public health and wellbeing. The US government appropriated $5.4 Billion for FY2015 and WHO proposed a$100 Million emergency fund largely to curtail the threat of future outbreaks. Using epidemiological analyses and economic modeling, we propose that the best use of these and similar funds would be to serve as global insurance against the continued threat of emerging infectious diseases. An effective strategy would involve the initial investment in strengthening mobile and adaptable capacity to deal with the threat and reality of disease emergence, coupled with repeated investment to maintain what is effectively a �national guard� for pandemic prevention and response. This investment would create a capital stock that could also provide access to safe treatment during and between crises in developing countries, lowering risk to developed countries.Ye

Association between body condition score and live weight in pasture-based Holstein-Friesian dairy cows

peer-reviewedThe objective was to quantify the strength of the relationship between body condition score (BCS) and live weight (LW) in pasture-based Holstein-Friesian dairy cattle, and to determine the kg LW per unit BCS. A total of 26021 test-day records with information on both BCS (1–10 scale, where 1 is emaciated and 10 is obese) and LW across 1110 lactations from one research farm were used in the analysis. Correlation and regression analyses were used to determine the degree of association between BCS and LW in different parities, stages of the inter-calving interval and years. Correlations between BCS and LW were relatively consistent, with the mean correlation between BCS and LW across all data of 0·55 implying that differences in BCS explain approximately 30% of the variation in LW. Significantly different regressions of LW on BCS were present within stage of inter-calving interval by parity subclasses. Excluding calving, LW per unit BCS varied from 17 kg (early to mid lactation in parity 1) to 36 kg (early lactation in parity 4 and 5). However, LW per unit BCS was greatest at calving varying from 44 kg in first parity animals to 62 kg in second parity animals. On average, 1 BCS unit equated to 31 kg LW across all data

An Investigation Into Food Neophobia and Cultural Intelligence: Evidence From Business Classes

This study investigated the relationship between food neophobia, the tendency to avoid new foods, and cultural intelligence (CQ). A questionnaire was administered to undergraduate students at a university in the Northwestern United States. Survey administration occurred during the 2018-2019 academic year. The questionnaire included a combination of demographic questions along with two validated survey instruments, the Cultural Intelligence Scale (CQS) (Ang & Dyne, 2008) and the Food Neophobia Scale (FNS) (Pliner & Hobden, 1992). CQS was used to measure cultural intelligence and FNS gauged food neophobia. Results indicated a strong correlation between CQ and food neophobia. An analysis of CQ’s components showed that the significant drivers of the results were metacognitive/strategy and motivational/drive CQ subconstructs

Technostress Creators in Higher Education During the Covid-19 Pandemic: A Comparison of Faculty Perceptions and Experiences

The purpose of this study is to advance the scholarship related to techno-distress in higher education. Two surveys were conducted during the COVID-19 pandemic of college and university professors to evaluate technostress creator perceptions. The Technostress Creators Scale (Tarafdar et al., 2007) was used to measure the technostress of college and university faculty early in the pandemic (2020), (n = 307) and one year later (2021), (n = 94). The cross-sectional quantitative study revealed that faculty technostress was markedly curbed throughout the periods of study, with a reduction in perceptions of computerphobia by nearly 20% comparing both samples. An analysis of the sub-dimensions clarifies this outcome

Poisson-Dirichlet branching random walks

We determine, to within O(1), the expected minimal position at level n in certain branching random walks. The walks under consideration have displacement vector (v_1,v_2,...), where each v_j is the sum of j independent Exponential(1) random variables and the different v_i need not be independent. In particular, our analysis applies to the Poisson-Dirichlet branching random walk and to the Poisson-weighted infinite tree. As a corollary, we also determine the expected height of a random recursive tree to within O(1).Comment: Published in at http://dx.doi.org/10.1214/12-AAP840 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org

SDO Onboard Ephemeris Generation

The Solar Dynamics Observatory (SDO) spacecraft is a sun-pointing, semi-autonomous satellite that will allow nearly continuous observations of the Sun with a continuous science data downlink. The science requirements for this mission necessitate very strict sun-pointing requirements, as well as continuous ground station connectivity through high gain antennas (HGAs). For SDO s onboard attitude control system to successfully point the satellite at the Sun and the HGAs at the ground stations with the desired accuracy, in addition to the need for accurate sensors it must have good onboard knowledge of the ephemerides of the Sun, the spacecraft, and the ground station. This paper describes the minimum force models necessary for onboard ephemeris generation in support of an attitude control system. The forces that were considered include the Sun s point mass, Moon s point mass, solar radiation pressure (SRP), and the Earth s gravity with varying degree and order of terms of the geopotential
