Researchers at The University of Texas at Arlington are studying the ideal physical and mental states to help children and adults pay attention and practice self-control, by combining computer-game testing with a simultaneous ongoing analysis of heart-rate and skin activity. "We know attention and self-regulation are critical for things like academic success, financial success, and general health and well-being," said Catherine Spann, a researcher at UTA's Learning Innovation and Networked Knowledge or LINK Research Lab and principal investigator of the study. "We think that if we understand the different physical and emotional states related to attention and self-regulation, we could develop targeted interventions for children and adults to achieve greater well-being," she added. Spann is currently conducting her Psychophysiology of Self-Regulation Study with volunteers age 7 and up, in collaboration with Research and Learning Center at the Fort Worth Museum of Science and History. Participants complete a questionnaire about general levels of attention and self-regulation in everyday life, report how they are feeling, and then complete an attention and self-regulation task on an iPad. They wear a wristband to track their heart rate and skin activity, which indicate how calm and engaged they are. "The wearable technology that we are using gives us information about their specific state and could tell us that they might not be ready to sit still and listen to a lecture or engage in certain learning activities," Spann said. Scores on the task are based on a combination of accuracy and reaction time. Spann is also examining how certain aspects of individuals such as gender, age and general self-regulation in daily life, impact how the body responds during a specific task requiring attention and self-regulation, especially when it comes to learning. George Siemens, executive director of the LINK Research Lab, underlined the importance of this research in the context of ongoing changes in education models. "In order to make wise investments in our school systems, we need to better understand the core of learning," Siemens said. "We need to understand the conditions under which people optimally learn and the ways that educators can best support students." "The work that Dr. Spann is doing at the museum gives us important insight into how the mindsets and self-regulation of students impacts their ability to learn," he added. Spann plans to discuss the preliminary findings of her study at the 2016 aWEAR Conference later this month. LINK is a research lab where researchers, educators and graduate students connect, share and collaborate in advancing social and technological networks, designing future learning models and exploring the future of higher education. LINK started with the MOOC Research Initiative Conference, funded by a grant from the Bill and Melinda Gates Foundation in 2013. Since that event, the lab has obtained a number of additional grants, developed a network of international scholars, initiated cutting-edge research projects, and collaborated with graduate students, faculty, and staff at UTA.

Review of Palaeobotany and Palynology | Year: 2010

Fossil leaf compressions from the Late Oligocene (27.23 Ma) Guang River flora of northwestern Ethiopia include a new record of Vepris and the earliest record of Clausena and the subfamily Aurantioideae. These fossils, along with most other African rutaceous fossils, are associated with a tropical moist forest community. The large number of Rutaceae taxa in eastern Africa during the Late Oligocene and Early Miocene is likely due to a radiation within Africa or dispersal to Africa associated with the continental expansion of moist tropical forest during this time interval. © 2009 Elsevier B.V.

Numerous fossil winged seeds from the early Miocene (22-21 MA) of Ethiopia represent the earliest and only definitive record of the ecologically and economically important legume genus Newtonia (Fabaceae: ''Mimoseae''). These fossils represent a new species and provide evidence that tropical moist forest persisted on the Ethiopian Plateau into the early Miocene. © 2012 by The University of Chicago.

Botanical Journal of the Linnean Society | Year: 2010

New species of caesalpinioid legumes, Cynometra sensu lato and Afzelia, are described from the Late Oligocene (27.23 Ma) Guang River flora in north-western Ethiopia. Both taxa show leaf characteristics that are shared with extant species in the Guineo-Congolian, Sudanian and/or Zambezian regions of Africa today. The presence of these two species in Ethiopia during the Palaeogene provides further evidence of the importance of the legume tribe Detarieae in northern and north-eastern Africa throughout much of the Cenozoic, even although the clade is poorly represented in these regions today. The fossil record documents a significant palaeogeographical and evolutionary history of Detarieae in Africa, especially compared with that of Europe and Anatolia. Based on this evidence, it is unlikely that significant diversification of extant African Detarieae took place on the Eurasian landmass. © 2010 The Linnean Society of London.

Palaeogeography, Palaeoclimatology, Palaeoecology | Year: 2011

Environmental disturbances profoundly impact the structure, composition, and diversity of modern forest communities. A review of modern studies demonstrates that important characteristics used to describe fossil angiosperm assemblages, including leaf margin type, plant form, plant diversity, insect herbivore diversity and specialization, and variation in herbivory among plant species, differ between early and late successional forests. Therefore, sequences of fossil floras that include a mix of early and later successional communities may not be appropriate to study long-term temporal trends or biotic effects of climate, latitude, or other variables.We conducted sedimentological, paleobotanical, and insect damage analyses at two contemporaneous late Oligocene (27-28. Ma) leaf localities in the Chilga Basin, northwest Ethiopia, to test the hypothesis that successional stage explains variation between the assemblages. The Guang River and Bull's Bellow fossil plant localities are stratigraphically equivalent and only 1.5. km apart, but they have no plant species in common. Sedimentary structures at Bull's Bellow suggest multiple episodes of deposition and a more disturbed environment than the single, featureless mudstone that composes the Guang River fossil unit. Bull's Bellow has a significantly higher percentage of plant species with toothed margins, lower plant and insect herbivore damage diversity, and less specialized herbivore damage than Guang. Furthermore, the nearest living relatives of many of the Bull's Bellow plant species are associated with early successional forests, whereas the Guang River plants are a mix of early and late successional species. Thus, the physiological and ecological attributes of the Guang flora are consistent with a more mature forest community, and the differences between the two floras emphasize the importance of collecting multiple floras from the same stratigraphic level in order to account for landscape-level ecological processes. More specifically, accurate estimates of diversity and feeding specialization in tropical, angiosperm-rich fossil assemblages are essential to address adequately the origin and persistence of relatively high species diversity in the modern tropics, and diversity differences between regions such as modern tropical Africa and South America. © 2011 Elsevier B.V.

Project Abstract
Collaborative Research: A multi-proxy approach to Early Miocene community, landscape, and climate reconstruction, Ethiopian Plateau
Technical Description: The Cenozoic rock record contains a rich and critically important history of varied climates and biotic communities, and these serve as aids to understanding current and future climatic and biotic change. While the scales are different, the deep geologic past provides test cases against which climate models can be compared or from which they can be created. However, spatial coverage by paleoclimate proxies is best for middle latitudes, and quite limited for the tropics and subtropics, especially in the terrestrial realm. This project will investigate a new extraordinary Early Miocene (22 Ma) site where carbonaceous shales and tuffaceous sediments preserve lagerstätten-quality fossils including abundant compressed leaves, fruits and seeds with exquisite cuticular features, complete frogs with both skeletal and soft body parts, fish and large mammal bones. These enable reconstruction of paleoclimate, pCO2, paleoecology, and significant biogeographic data for African flora, and perhaps fauna. The objectives of this project are to:
1. compare Early Miocene and Late Oligocene paleoclimate, paleoecology, and biogeography using multiple independent proxies.
2. provide pCO2 estimates from pedogenic goethite and stomatal indices.
3. provide Early Miocene paleoecological and paleoclimatological context for faunal evolution during an otherwise poorly known, but significant time interval for Africa.
4. address plant biogeographic questions, e.g. a decline in palm richness and importance
5. test methods by (a) comparing δD isotopes from aquatic and terrestrial lipids to test for enrichment of D due to evapotranspiration, (b) comparing goethite and stomatal index pCO2 data (c) evaluating the consistency of paleotemperature and precipitation reconstructions using methods based upon leaf physiognomy, overlapping ranges of plant taxa, qualitative and quantitative paleosol analyses, and multiple isotope geochemical proxies.
Non-technical Description and Broader Significance: This grant funds a multidisciplinary team of scientists who will sample rocks and fossils from the Ethiopian Plateau northeast of Addis Ababa to reconstruct past climate, vegetation, atmospheric CO2 concentration (pCO2), and the physical landscape 22 million years ago in an integrated and collaborative way. Team members, who have collaborated before on rocks from the Plateau that are 27 million years old, have expertise in the study of plant fossil identification, insect damage to fossil leaves, the reconstruction of past climate and ecology, the geochemistry of ancient soils and organic plant compounds, and geology. The locality preserves extraordinary plant fossils having cellular detail, smaller vertebrates including frogs with soft tissue preservation, and large mammal bones. The scientific significance of our work is that it will resolve currently conflicting data regarding global temperature and pCO2 between 27 million and 22 million years ago. Marine records show a significant rise in global temperature between these times, but some records of pCO2 show a decline and others a rise. Resolution of this conflict by acquisition of temperature and pCO2 data from one region using multiple independent sources will tell us if our understanding of CO2, in relation to global temperature is correct. Furthermore, the modern land connection between Africa and Eurasia was established about 24 million years ago, so we will be able to compare the younger plant and animal fossils with those from a time prior to contact with Eurasia. Africa?s flora and fauna was in a period of transition at this time, and its documentation is important for understanding the origins of modern biomes.
Educational outreach includes distance learning for thousands of K-12 students. This team has a history of blogs, currently hosted by the SMU Public Affairs office on the main website, and recently through the NY Times Scientist at Work pages. Students will be an integral part of this project ? this team has regularly taken students into the field and will continue to do so. We also plan to host an Ethiopian graduate student for training in the U.S.
