Summer Cook Associate Professor of Kinesiology (COLA) travels to Australia

I was partially supported by a CIE International development grant to travel to Perth, Australia for one month in 2016. Dr. Timothy Fairchild, a colleague and friend, invited me to visit the Department of Psychology and Exercise Science at Murdoch University in the hopes of establishing a research relationship with the University of New Hampshire Department of Kinesiology. Over the last several years, I have had students earn Summer Undergraduate Research Fellowships (SURF) from the Hamel Center and have always wanted to give students an opportunity to apply for SURF abroad grants or to study abroad while conducting research within our field. The idea of international collaboration and the opportunity to leave the New England winter to work on the coast of Western Australia made the decision to travel very simple

Full Scale Drag Tests on Various Parts of Fairchild (FC-2W2) Cabin Monoplane

The drag due to the various parts of a Fairchild (FC-2W2) cabin monoplane was measured at air speeds varying from 50 to 100 m.p.h., in the Twenty-Foot Propeller Research Tunnel of the National Advisory Committee for Aeronautics. It was found that the largest drag was due to the radial air-cooled engine. The measured drag due to the landing gear was also large, being about 4/5 of that due to the engine. Substituting Musselman type wheels for the standard wheels caused no change in the drag due to the landing gear. A small decrease in drag was effected by adding a turtle back to the airplane fuselage

Annotated Checklist of the Fish Species Observed at the Gordon Natural Area (West Chester University, PA) 1997-2019. Version I

Summary Data Number of Taxa: 14 Species, in 13 Genera, 6 Families, and 5 Orders. Description Investigation of the ichthyofauna (i.e., fish) of the GNA began has a fairly long-history, but has been sporadic and the findings have been poorly archived. The earliest known research was undertaken by former WCU Biology Professor Win Fairchild. Regrettably, we only have his data from a single study (Butler & Fairchild 2005). WCU graduate student Danielle DiFederico (one of Win Fairchild\u27s students) conducted her Master\u27s research in Plum Run in the early 2000. Following this, there was a long fallow period (with just a single observation having been recorded from 2005 through 2017). In recent years, however, the Stroud Water Research Center has been conducting annual surveys in Plum Run within the boundaries of the GNA. Data from that research have been incorporated here. It is hoped that moving forward, ichthyological research will be a much more regular feature at the GNA. Status/Threats IUCN Status: Data are from the IUCN Red List of Threatened Species (IUCN 2020). The GNA checklist was compared with the Pennsylvania Natural Heritage Environmental Review List (PNHP 2020). None of the eighty-eight fish species listed on the environmental review list are known to occur in the GNA. The checklist was also compared with species listed in the Chester County Natural Heritage Inventory (PNHP 2015). None of the fish species known for the GNA were listed as being of special concern in Chester County

Modification and preservation of environmental signals in speleothems

Speleothems are primarily studied in order to generate archives of climatic change and results have led to significant advances in identifying and dating major shifts in the climate system. However, the climatological meaning of many speleothem records cannot be interpreted unequivocally; this is particularly so for more subtle shifts and shorter time periods, but the use of multiple proxies and improving understanding of formation mechanisms offers a clear way forward. An explicit description of speleothem records as time series draws attention to the nature and importance of the signal filtering processes by which the weather, the seasons and longer-term climatic and other environmental fluctuations become encoded in speleothems. We distinguish five sources of variation that influence speleothem geochemistry: atmospheric, vegetation/soil, karstic aquifer, primary speleothem crystal growth and secondary alteration and give specific examples of their influence. The direct role of climate diminishes progressively through these five factors. \ud \ud We identify and review a number of processes identified in recent and current work that bear significantly on the conventional interpretation of speleothem records, for example: \ud \ud 1) speleothem geochemistry can vary seasonally and hence a research need is to establish the proportion of growth attributable to different seasons and whether this varies over time. \ud \ud 2) whereas there has traditionally been a focus on monthly mean Ã�´18O data of atmospheric moisture, current work emphasizes the importance of understanding the synoptic processes that lead to characteristic isotope signals, since changing relative abundance of different weather types might 1Corresponding author, fax +44(0)1214145528, E-mail: [email protected] control their variation on the longer-term. \ud \ud 3) the ecosystem and soil zone overlying the cave fundamentally imprint the carbon and trace element signals and can show characteristic variations with time. \ud \ud 4) new modelling on aquifer plumbing allows quantification of the effects of aquifer mixing. \ud \ud 5) recent work has emphasized the importance and seasonal variability of CO2-degassing leading to calcite precipitation upflow of a depositional site on carbon isotope and trace element composition of speleothems. \ud \ud 6) Although much is known about the chemical partitioning between water and stalagmites, variability in relation to crystal growth mechanisms and kinetics is a research frontier. \ud \ud 7) Aragonite is susceptible to conversion to calcite with major loss of chemical information, but the controls on the rate of this process are obscure. \ud \ud Analytical factors are critical to generate high-resolution speleothem records. A variety of methods of trace element analysis are available, but standardization is a common problem with the most rapid methods. New stable isotope data on Irish stalagmite CC3 compares rapid laser-ablation techniques with the conventional analysis of micromilled powders and ion microprobe methods. A high degree of comparability between techniques for Ã�´18O is found on the mm-cm scale, but a previously described high-amplitude oxygen isotope excursion around 8.3 ka is identified as an analytical artefact related to fractionation of the laser-analysis associated with sample cracking. High-frequency variability of not less than 0.5o/oo may be an inherent feature of speleothem Ã�´18O records

Does comorbid anxiety counteract emotion recognition deficits in conduct disorder?

Background: Previous research has reported altered emotion recognition in both conduct disorder (CD) and anxiety disorders (ADs) - but these effects appear to be of different kinds. Adolescents with CD often show a generalised pattern of deficits, while those with ADs show hypersensitivity to specific negative emotions. Although these conditions often cooccur, little is known regarding emotion recognition performance in comorbid CD+ADs. Here, we test the hypothesis that in the comorbid case, anxiety-related emotion hypersensitivity counteracts the emotion recognition deficits typically observed in CD. Method: We compared facial emotion recognition across four groups of adolescents aged 12-18 years: those with CD alone (n = 28), ADs alone (n = 23), cooccurring CD+ADs (n = 20) and typically developing controls (n = 28). The emotion recognition task we used systematically manipulated the emotional intensity of facial expressions as well as fixation location (eye, nose or mouth region). Results: Conduct disorder was associated with a generalised impairment in emotion recognition; however, this may have been modulated by group differences in IQ. AD was associated with increased sensitivity to low-intensity happiness, disgust and sadness. In general, the comorbid CD+ADs group performed similarly to typically developing controls. Conclusions: Although CD alone was associated with emotion recognition impairments, ADs and comorbid CD+ADs were associated with normal or enhanced emotion recognition performance. The presence of comorbid ADs appeared to counteract the effects of CD, suggesting a potentially protective role, although future research should examine the contribution of IQ and gender to these effects
