Towards Using A Physio-Cognitive Model In Tutoring For Psychomotor Tasks., Jong W. Kim, Chris Dancy, Robert A. Sottilare
Faculty Conference Papers and Presentations
We report our exploratory research of psychomotor task training in intelligent tutoring systems (ITSs) that are generally limited to tutoring in the desktop learning environment where the learner acquires cognitively oriented knowledge and skills. It is necessary to support computer-guided training in a psychomotor task domain that is beyond the desktop environment. In this study, we seek to extend the current capability of GIFT (Generalized Intelligent Frame-work for Tutoring) to address these psychomotor task training needs. Our ap-proach is to utilize heterogeneous sensor data to identify physical motions through acceleration data from a smartphone and to monitor respiratory activity through …
Discerning Service: The Leader As Servant And The Ignatian Tradition, Luke Lavin
Discerning Service: The Leader As Servant And The Ignatian Tradition, Luke Lavin
International Journal of Servant-Leadership
Throughout his spiritual autobiography, Ignatius of Loyola humbly refers to himself as the pilgrim. Ironically, it is a group of pilgrims in Herman Hesse s The Journey to The East that inspires Robert Greenleaf s understanding of the servant as leader. In the late 16th century, Ignatius witnessed and was a product of the turbulent European Reformation the reason infusion of the Renaissance, and the expansive globalization of the Age of Exploration. Greenleaf, an executive for AT&T throughout the mid-twentieth century, witnessed the American countercultural movement of the nineteen sixties and the institutionalization of the American workplace. Both men provided …

My Father As A Lifelong Servant-Leader, Jonathan Potter
International Journal of Servant-Leadership
My father, Ted Potter, is supposedly retired. He has had a long, interesting, and varied career, first as a teacher, then as a real estate agent, broker, appraiser, and consultant. Although my dad has not formally studied the literature of servant-leadership, I believe his life and work exemplify much of what Greenleaf and other scholars have conceptualized as characteristic of the servant-leader approach to interpersonal and organizational management and leadership. Over the course of a few days at the end of summer, as the leaves on the trees began turning on their fall flare, I engaged my dad in an …

Intermittent rivers and ephemeral streams (IRES) encompass fluvial ecosystems that eventually stop flowing and run dry at some point in space and time. During the dry phase, channels of IRES consist mainly of dry riverbeds (DRBs), prevalent yet widely unexplored ecotones between dry and wet phases that can strongly influence the biogeochemistry of fluvial networks. DRBs are often overlooked because they do not strictly belong to either domain of soil or freshwater science. Due to this dual character of DRBs, we suggest that concepts and knowledge from soil science can be used to expand the understanding of IRES biogeochemistry. Based …

Reports
Research on engineered nanomaterials (ENM) has progressed rapidly from the very early stages of studying their unique, size-dependent physicochemical properties and commercial exploration to the development of products that influence our everyday lives. We have previously reviewed various methods for synthesis, surface functionalization, and analytical characterization of ENM in a publication titled 'Engineered Nanomaterials: Preparation, Functionalization and Characterization'. In this second, inter-linked document, we first provide an overview of important applications of ENM in products relevant to human healthcare and consumer goods, such as food, textiles, and cosmetics. We then highlight the challenges for the design and development of new …

High Sensitivity Temperature Sensor Based On Singlemode-No-Core- Singlemode Fibre Structure And Alcohol, Ke Tiana, Gerald Farrell, Xianfan Wang, Yifan Xin, Yanqiu Du, Wenlei Yang, Haidong Liang, Elfed Lewis, Pengfei Wang
Articles
A high sensitivity temperature sensor based on a singlemode-no-core-singlemode (SNCS) fibre structure and surrounded with alcohol within a silica capillary is described. In this investigation, no-core fibre (NCF) is used as the multimode waveguide and alcohol is chosen as the temperature sensitive medium. By packaging the alcohol solution with a short length of NCF enclosed within a silica capillary, the surrounding temperature can be detected by monitoring the variations of transmission loss at a specific wavelength. The theoretical analysis predicts this temperature sensor can provide high sensitivity, and the experimental results support this. The maximum temperature sensitivity of the sample …

Origins Of Animal Cell Adhesion, Jennyfer Mora Mitchell
Origins Of Animal Cell Adhesion, Jennyfer Mora Mitchell
Electronic Theses and Dissertations
A fundamental requirement for multicellularity is cell adhesion. This includes mechanisms by which cells adhere to each other and to their secreted extracellular matrix (ECM). Two well characterized adhesion complexes in animals include: 1) adherens junctions (AJs), which are involved in cell-cell adhesion and composed of cadherin receptors, p120-, α- and β-catenin, and 2) focal adhesions (FAs), which are involved in cell-ECM adhesion and include proteins such as integrins, vinculin, paxillin, talin and focal adhesion kinase (FAK). The molecular components of AJs are widely conserved in animals, and largely absent in non-animals. In contrast, the molecular components of FAs have …

Developmentally Appropriate Practice In The 21st Century, Kay Sanders, Flora Farago
Faculty Publications
Developmentally appropriate practice (DAP) is a set of early childhood curricular recommendations published by the National Association for the Education of Young Children (NAEYC). DAP was introduced in the United States in the late 1980s through Bredekamp’s (1987) seminal work, “Developmentally Appropriate Practice in Early Childhood Programs Serving Children from Birth through Age 8.” Since the initial publication, DAP has been widely accepted as the standard for early childhood educational practice in the United States and in Westernized countries around the world. Whereas proponents of DAP assert its positive influence on children, those more critical of DAP question whether it …

Sequestered Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Provide Variable Protection From Microbial Pathogens, K. J. Hovey, E. M. Seiter, Erin E. Johnson, Ralph Saporito
Sequestered Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Provide Variable Protection From Microbial Pathogens, K. J. Hovey, E. M. Seiter, Erin E. Johnson, Ralph Saporito
2018 Faculty Bibliography
Most amphibians produce their own defensive chemicals; however, poison frogs sequester their alkaloid-based defenses from dietary arthropods. Alkaloids function as a defense against predators, and certain types appear to inhibit microbial growth. Alkaloid defenses vary considerably among populations of poison frogs, reflecting geographic differences in availability of dietary arthropods. Consequently, environmentally driven differences in frog defenses may have significant implications regarding their protection against pathogens. While natural alkaloid mixtures in dendrobatid poison frogs have recently been shown to inhibit growth of non-pathogenic microbes, no studies have examined the effectiveness of alkaloids against microbes that infect these frogs. Herein, we examined …
Thought Experiment As An Interdisciplinary Pedagogy, Sharon M. Kaye
Thought Experiment As An Interdisciplinary Pedagogy, Sharon M. Kaye
2018 Faculty Bibliography
The thesis of this paper is that thought experiments provide an especially powerful way to frame a class discussion. They work for students for the same reason that they have worked for great geniuses (such as Einstein) through the ages—namely, because they are interdisciplinary. Competing rationalist and empiricist accounts of how thought experiments work suggest that they will engage both rationally- and empirically-minded students. Examples of student responses to thought experiments confirm that they bring out interestingly diverse ways of thinking. Concern that interdisciplinary pedagogy makes genuine communication impossible has led some theorists to insist on a methodological pluralism that …

2018 Faculty Bibliography
Geitleria was described from a limestone cave in Israel, and subsequently reported from caves of France, Romania, Spain, Florida, Costa Rica, and Cook Islands. It is morphologically unusual in that it has true branching, but no heterocytes. A morphologically distinct species of Geitleria was recently collected from a limestone cave in Great Smoky Mountains National Park, Tennessee, and is herein described as G. appalachiana sp. nov. Sequence data for 16S rRNA and rpoC1 loci for the species were obtained from field material using single filament PCR. Phylogenetic evidence indicates that Geitleria does not belong to any family in the Nostocales …

2018 Faculty Bibliography
South Ural is a territory with a unique geographical position and heterogeneous natural conditions. Unexplored biodiversity of the terrestrial cyanobacteria of this territory is very high. We undertook a floristic study covering all botanical-geographical zones of the Bashkiria and Bredinskiy district of the Chelyabinsk region. In a total of 85 soil samples collected, 56 species of cyanobacteria were identified. The number of cyanobacteria was highest in the boreal-forest zone (39 species) and notably lower in the other zones (18, 29, and 24 species for broad-leaved forest, forest steppe and steppe regions, respectively). Leptolyngbya voronichiniana, Leptolyngbya foveolarum, cf. Trichocoleus hospitus, Pseudophormidium …

2018 Faculty Bibliography
Twelve strains of Leptolyngbya-like filaments were isolated from biological soil crust samples from two localities in the Central Region of Mexico. The strains were morphologically distinguished from most Synechococcalean species by the obligate presence of a blackish sheath. Phylogenetic analysis based on 16S rRNA gene sequence placed all strains into a strongly supported single clade sister to Scytolyngbya. The genetic identity between our strains and all other Synechococcales, including Scytolyngbya, was less than 95%, and the strains were further distinguished by morphology and terrestrial ecology. The conserved domains of the 16S-23S ITS region had secondary structures distinct from all other …

Behavioural Preference For Low Levels Of Uv-B Radiation In Two Neotropical Frog Species From Costa Rica, Joseph A. Demarchi*, Andrew Britton**, Kaylee O'Donnell**, Ralph Saporito
2018 Faculty Bibliography
Tropical frogs experience damaging effects from exposure to UV-B radiation, and some diurnally active, con- spicuous species exhibit avoidance behaviours to high levels of UV-B. To determine if similar behaviours are present in
other diurnal frogs, we experimentally compared UV-B avoidance in two common species of neotropical diurnal frogs – Oophaga pumilio, an aposematic poison frog and Craugastor bransfordii, a cryptic leaf-litter frog – in response to different levels of UV-B. Wild-caught frogs were tested in experimental arenas fitted with filters that permitted two different levels of UV-B (low: 14% vs. high: 84% UV-B). Both species spent significantly more time …

Male Mate Preference As An Agent Of Fecundity Selection In A Polymorphic Salamander, Kortney E. Jaworski, Matthew S. Lattanzio, Cari-Ann M. Hickerson, Carl D. Anthony
2018 Faculty Bibliography
Color polymorphisms are associated with variation in other traits which may affect individual fitness, and these color‐trait associations are expected to contribute to nonrandom mating in polymorphic species. The red‐backed salamander (Plethodon cinereus) exhibits a polymorphism in dorsal pattern: striped and unstriped, and previous studies have suggested that they may mate nonrandomly. However, the mechanism(s) contributing to this behavior remain unclear. Here we consider the role that male preference may have in driving mating behavior in P. cinereus. We limit our focus to striped individuals because this morph is most likely to be choosy given their dominant, aggressive behavioral profiles …

Mitochondrial Dna Analysis Of Mazahua And Otomi Indigenous Populations From Estado De Mexico Suggests A Distant Common Ancestry, Angelica GonzáLez-Oliver, Ernesto Garfias-Morales, D G. Smith, Mirsha Quinto-Sánchez
Human Biology Open Access Pre-Prints
The indigenous Mazahua and Otomi have inhabited the same localities in Estado de Mexico since pre-Columbian times. Their languages, Mazahua and Otomi, belong to the Otomanguean linguistic family, and, while they share cultural traditions and a regional history that suggest close genetic relationships and common ancestry, the historical records concerning their origin are confusing. To understand the biological relationships between Mazahua and Otomi we analyzed the mitochondrial DNA (mtDNA) genetic variation. We identified the mtDNA haplogroups by restriction fragment length polymorphism typing and sequenced the hypervariable region I of the mtDNA control region in 141 Mazahua and 100 Otomi. These …
Chickens Play To The Crowd, Cinzia Chiandetti
Chickens Play To The Crowd, Cinzia Chiandetti
Animal Sentience
The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.
Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley
Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley
Animal Sentience
Peña-Guzmán’s depiction of the opponent of animal suicide as a conservative is a straw man. It is possible to accept that animals are self-conscious and reflexive yet still reject the view that they have the mental wherewithal to commit run-of-the-mill suicide. That animal behaviour can be positioned on a continuum of self-destructive behaviour does not establish that animals can intentionally kill themselves.
An Adaptationist Perspective On Animal Suicide, Timothy P. Racine
An Adaptationist Perspective On Animal Suicide, Timothy P. Racine
Animal Sentience
Peña-Guzmán’s discussion of suicide in nonhuman animals has broad implications. In this commentary, I focus on the logical relation between suicide and intention. Proximate cause must be distinguished from ultimate function in explanations of suicide. I briefly discuss two adaptationist accounts of suicidal behavior.
Lessons From Chimpanzee Sign Language Studies, Mary Lee Jensvold
Lessons From Chimpanzee Sign Language Studies, Mary Lee Jensvold
Animal Sentience
Claims are often made about behaviors being unique to humans; the evidence usually shows they are not. Sign language studies on chimpanzees may provide a useful model for comparative studies of suicide. A productive approach to comparative studies is to focus on observable behaviors rather than getting lost in the pitfalls of vague definitions and changing measures.
Animal Suicide: An Account Worth Giving?, Irina Mikhalevich
Animal Suicide: An Account Worth Giving?, Irina Mikhalevich
Animal Sentience
Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom. He defends a “continuist” account in which suicide is a multiply-realizable phenomenon characterized by self-injurious and self-annihilative behaviors. This view is problematic for several reasons. First, it appears to mischaracterize the Darwinian view that mind is continuous in nature. Second, by focusing only on surface-level features of behavior, it groups causally and etiologically disparate phenomena under a single conceptual umbrella, thereby reducing the account’s explanatory power. Third, it obscures existing analyses of suicide in biomedical ethics and …

Predicting Market Squid (Doryteuthis Opalescens) Landings From Pre-Recruit Abundance, Stephen Ralston, Emmanis Dorval, Laura Ryley, Keith M. Sakuma, John C. Field
United States Department of Commerce: Staff Publications
The fishery for market squid (Doryteuthis opalescens) in California is typical of many of the world’s cephalopod fisheries, in that a very short life span and the effect of environmental forcing on recruitment result in enormous interannual variability in catches and population size. We evaluate the utility of a pre-recruit index of squid abundance that is based on midwater trawl sampling in the 3–5 months preceding the onset of the fishery as a basis for predicting landings. Catches in the survey largely represent squid in the 30–50 mm dorsal mantle length size range, representing individuals 30–90 day old. …
