  Citation × Citation Citation Abstract Copy Title: What Does Accuracy Get You? Empathic Accuracy During a Negotiation. Author: Howington, Devin Year: 2017 Accurately guessing the thoughts and feelings of another person, known as empathic accuracy, is thought to be a useful skill across many domains. However, the evidence supporting the value of empathic accuracy has been mixed, perhaps because the domains previously examined did not require accuracy for functionality. Negotiation may be one domain in which being accurate really matters for positive outcomes for the perceiver. Additionally, men and women may have different motivations to be accurate, including the presence of a competitive or cooperative situation. The primary research questions of this study are: 1) Is empathic accuracy related to outcomes in the negotiation?; 2) Is accuracy dependent on how the negotiation is framed?; and 3) Does how the negotiation is framed affect men’s and women’s empathic accuracy differently? Individual differences in personal power and Machiavellianism are also examined in relation to accuracy in this context. In this study, 336 participants interacted in same-sex dyads to negotiate over small items in either a competitive or cooperative context, resulting in a 2 (gender) x 2 (context) design. Accuracy was measured both as empathic accuracy for partner’s thoughts during the negotiation as well as accuracy for guessing their partner’s idiosyncratic item preferences (provided prior to the negotiation). Actor-Partner Interdependence models were used to estimate the contributions of each person in the dyad to the outcome of interest. Neither empathic accuracy nor accuracy for guessing item values led to any increases in personal gain in the negotiation. However, empathic accuracy was predictive of satisfaction with the outcome of the negotiation, such that more accurate actors and having more accurate partners both led to significantly increased satisfaction with the outcome. Contrary to the hypotheses, accuracy was not affected by gender or the framing of the negotiation or any interactions between the two variables. Individual differences in power and Machiavellianism did not lead to increases in perceiver empathic accuracy, but rather led to decreases in partner’s accuracy: actors that had partners who were high in power or high in Machiavellianism were less empathically accurate. The implications for negotiation research and future empathic accuracy research are discussed. Title: What Does Accuracy Get You? Empathic Accuracy During a Negotiation.

  Citation × Citation Citation Abstract Copy Title: A Hierarchical Modeling Approach to Simulating the Geomorphic Response of River Systems to Climate Change Author: Praskievicz, Sarah Year: 2014 Anthropogenic climate change significantly affects water resources. River flows in mountainous regions are driven by snowmelt and are therefore highly sensitive to increases in temperature resulting from climate change. Climate-driven hydrological changes are potentially significant for the fluvial geomorphology of river systems. In unchanging climatic and tectonic conditions, a river's morphology will develop in equilibrium with inputs of water and sediment, but climate change represents a potential forcing on these variables that may push the system into disequilibrium and cause significant changes in river morphology. Geomorphic factors, such as channel geometry, planform, and sediment transport, are major determinants of the value of river systems, including their suitability for threatened and endangered species and for human uses of water. This dissertation research uses a hierarchical modeling approach to investigate potential impacts of anthropogenic climate change on river morphology in the interior Pacific Northwest. The research will address the following theoretical and methodological objectives: 1) Develop downscaled climate change scenarios, based on regional climate-model output, including changes in daily minimum and maximum temperature and precipitation. 2) Estimate how climate change scenarios affect river discharge and suspended-sediment load, using a basin-scale hydrologic model. 3) Examine potential impacts of climate-driven hydrologic changes on stream power and shear stress, bedload sediment transport, and river morphology, including channel geometry and planform. The downscaling approach, based on empirically-estimated local topographic lapse rates, produces high-resolution climate grids with positive forecast skill. The hydrologic modeling results indicate that projected climate change in the study rivers will change the annual cycle of hydrology, with increased winter discharge, a decrease in the magnitude of the spring snowmelt peak, and decreased summer discharge. Geomorphic modeling results suggest that changes in reach-averaged bedload transport are highly sensitive to likely changes in the recurrence interval of the critical discharge needed to mobilize bed sediments. This dissertation research makes an original contribution to the climate-change impacts literature by linking Earth processes across a wide range of spatial scales to project changes in river systems that may be significant for management of these systems for societal and ecological benefits. This dissertation includes unpublished co-authored material.

  Citation × Citation Citation Abstract Copy Title: Measurement of Membrane Rigidity and Its Modulation by the Vesicle Trafficking Protein Sar1 Author: Loftus, Andrew Year: 2014 Sculpting membranes into dynamic, curved shapes is central to intracellular cargo trafficking and other cellular functions. However, generation of membrane curvature during trafficking involves lipids and membrane-associated proteins; current mechanisms focus on creating rigid cages, curved scaffolds, or membrane surface area changes by proteins. This dissertation provides an alternative mechanistic example for the control of membrane deformations, involving modulation of membrane material properties. Sar1, a GTPase of the COPII family, regulates vesicle trafficking from the endoplasmic reticulum. We find that Sar1p lowers the rigidity of the lipid bilayer membrane to which it binds. We examine the behavior of Saccharomyces cerevisiae Sar1 (Sar1p) and Homo sapiens paralogs of Sar1 (Sar1A and Sar1B). Like Sar1p, human Sar1s lower membrane rigidity. Unlike Sar1p, the rigidity is not a monotonically decreasing function of concentration. At high concentrations, we find increased bending rigidity and decreased protein mobility. These features imply a model in which human Sar1 clustering governs membrane mechanical properties. Membrane rigidity measurements remain rare, however, and show a large variance, a situation that can be addressed by improving techniques and comparing disparate techniques applied to the same systems. I introduce applying selective plane illumination microscopy (SPIM) to image thermal fluctuations of giant vesicles. SPIM's optical sectioning enables high-speed fluorescence imaging of freely suspended vesicles and quantification of edge localization precision, yielding robust fluctuation spectra and rigidity estimates. For lipid-only membranes and membranes bound by the intracellular trafficking protein Sar1p, we show rigidity values from giant unilamellar vesicle fluctuations in close agreement with those derived from our independent assay based on membrane tether pulling. We also show that a model of homogeneous quasi-spherical vesicles poorly fits fluctuation spectra of vesicles bound by Sar1A at high concentrations, suggesting that SPIM-based analysis can offer insights into spatially inhomogeneous properties. I conclude by discussing our current work on amphipathic alpha helices, their ability to reduce membrane rigidity, and our hopes to create artificial helical structures capable of mimicking trafficking systems. Supplemental videos represent membrane disintegration with Sar1p and fluctuations of membrane only and Sar1p incubated vesicles. This dissertation contains previously published co-authored material.

  Citation × Citation Citation Abstract Copy Title: The History of the Internet in Thailand Author: Palasri, Sirin, Huter, Steven, Wenzel, Zita Year: 2013 Thailand was an early participant in bringing the Internet to Asia, and it has a fascinating, but little-known, networking history. The grassroots efforts by a few dedicated and visionary university professors have resulted in a fully functional national network, despite the limited infrastructure and numerous technical obstacles of the early days. In fact, networking in Thailand began when virtually nothing existed in the country to establish a viable computer network. Telephone density was low, technical knowledge was scarce, and computers were expensive. However, some Thai engineers managed to create the academic network with a small budget and some technical assistance from Australia. Beginning with a UUCP connection and X.25 in 1987, the Thai academic network gradually transitioned to full TCP/IP in 1992. Boosted by the strong economic growth of the early ’90s, collaboration occurred with the private sector and was augmented by international financial support. The use of the Internet in Thailand is now highly valued, especially by the younger generation. Currently, the Internet is not only a significant tool for information sharing among academics and students, but also an alternative media and a new business opportunity for Thais. The state of academic networking in Thailand has grown significantly, reaching almost every university and research institution in the country. Many Thai schools and universities are using the Internet and its applications in their curricula. The government is planning to invest more in Information Technology (IT) and human resources by improving the telecommunications infrastructure and providing more education. As of this writing, Thailand has 16 Internet Service Providers (ISPs) operating nationwide with a combined leased line capacity above 30Mbps.
