    Interpreting Emojis: Millennials versus Non-Millennials

    The presence of emoticons--and now emojis--within written messages has increased since the advent of electronic communication. We conducted a quasi-experiment to learn whether a “smirk” emoji would be interpreted as indicating seductiveness by digital natives (Millennials) and non-digital natives (non-Millennials). We surveyed participants (N = 283) and asked them how they interpreted a message that contained the “smirk” emoji. Millennials were more likely than non-Millennials to infer seductiveness from this emoji. Our data suggest age-related differences in how various nonverbal cues are interpreted within electronic communication mediums

    The Agriculture Mechanics Laboratory – Safety and Capacities

    The agricultural mechanics laboratory, that is a part of the agricultural science and technology instructional program in Texas public schools, has over the years become a key component of the instructional program. Four classes, as outlined in the Texas Essential Knowledge and Skills (TEKS) that focus on mechanical skills and include: Principles of Agricultural, Food, and Natural Resources, Agricultural Mechanics and Metal Technologies, Agricultural Facilities Design and Fabrication and Agricultural Power Systems. Most agricultural mechanics laboratories are used 4 to 5 class periods per day sometimes with more than one class at a time meeting in the facility,. The questions that arises is how safe are the labs and are they equipped to handle the classes and number of students in each class. This study was a preliminary study conducted as a part of the AGD 581 Methods of Teaching Agriculture in the Public School. Six graduate students visited 11 high schools and compiled data in the following areas: foot candles of light available, hours of use per day, and safety equipment, etc. The results will be shared with the participants

    Electrochromic Radiator Coupon Level Testing and Full Scale Thermal Math Modeling for Use on Altair Lunar Lander

    In order to control system and component temperatures, many spacecraft thermal control systems use a radiator coupled with a pumped fluid loop to reject waste heat from the vehicle. Since heat loads and radiation environments can vary considerably according to mission phase, the thermal control system must be able to vary the heat rejection. The ability to "turn down" the heat rejected from the thermal control system is critically important when designing the system. Electrochromic technology as a radiator coating is being investigated to vary the amount of heat rejected by a radiator. Coupon level tests were performed to test the feasibility of this technology. Furthermore, thermal math models were developed to better understand the turndown ratios required by full scale radiator architectures to handle the various operation scenarios encountered during a mission profile for the Altair Lunar Lander. This paper summarizes results from coupon level tests as well as the thermal math models developed to investigate how electrochromics can be used to increase turn down ratios for a radiator. Data from the various design concepts of radiators and their architectures are outlined. Recommendations are made on which electrochromic radiator concept should be carried further for future thermal vacuum testing

    Preserving the Science Legacy from the Apollo Missions to the Moon

    Six Apollo missions landed on the Moon from 1969-72, returning to Earth 382 kg of lunar rock, soil, and core samples-among the best documented and preserved samples on Earth that have supported a robust research program for 45 years. From mission planning through sample collection, preliminary examination, and subsequent research, strict protocols and procedures are followed for handling and allocating Apollo subsamples. Even today, 100s of samples are allocated for research each year, building on the science foundation laid down by the early Apollo sample studies and combining new data from today's instrumentation, lunar remote sensing missions and lunar meteorites. Today's research includes advances in our understanding of lunar volatiles, lunar formation and evolution, and the origin of evolved lunar lithologies. Much sample information is available to researchers at curator.jsc.nasa.gov. Decades of analyses on lunar samples are published in LPSC proceedings volumes and other peer-reviewed journals, and tabulated in lunar sample compendia entries. However, for much of the 1969-1995 period, the processing documentation, individual and consortia analyses, and unpublished results exist only in analog forms or primitive digital formats that are either inaccessible or at risk of being lost forever because critical data from early investigators remain unpublished. We have initiated several new efforts to rescue some of the early Apollo data, including unpublished analytical data. We are scanning NASA documentation that is related to the Apollo missions and sample processing, and we are collaborating with IEDA to establish a geochemical database called Moon DB. To populate this database, we are working with prominent lunar PIs to organize and transcribe years of both published and unpublished data. Other initiatives include micro-CT scanning of complex lunar samples to document their interior structure (e.g. clasts, vesicles); linking high-resolution scans of Apollo film products to samples; and new procedures for systematic high resolution photography of samples before additional processing, enabling detailed 3D reconstructions of the samples. All of these efforts will provide comprehensive access to Apollo samples and support better curation of the samples for decades to come
