Input Distribution Influences Degree Of Auxiliary Use By Children With Specific Language Impairment, Laurence B. Leonard, Patricia Deevy

Purdue Center for Early Learning Faculty and Staff Publications

Children with specific language impairment (SLI) show a protracted period of inconsistent use of tense/agreement morphemes. The purpose of this investigation was to determine whether this inconsistent use could be attributed to the children’s misinterpretations of particular syntactic structures in the input. In Study 1, preschool-aged children with SLI and typically developing peers heard sentences containing novel verbs preceded by auxiliary was or sentences in which the novel verb formed part of a nonfinite subject-verb sequence within a larger syntactic structure (e.g. We saw the dog relling ). The children were then tested on their use of the novel verbs …

Qualitative Research To Improve Teaching Of Experimental, Ethical And Quantitative (Teeq) Biology, Samiksha Neroorkar, Nathaniel Mcintyre, Onyeka Uzomah, Ellen Gundlach, Nancy Pelaez

PIBERG Presentations

Qualitative research is very useful in undergraduate biology education. As we are dealing with adult students, we can constructively use their input on how to make improvements to course instructional systems. In a freshman biology course, we implemented a Calibrated Peer Review system to introduce students to the experimental, ethical and quantitative aspects of biology. Students were involved in writing assignments, followed by grading peer work based on criteria, pre-determined by the instructors. At the end of the course, students were interviewed in focus groups to take their feedback on aspects of CPR like benefits, improvements, challenges, relevance to their …

Collective Action And The Urban Commons, Sheila R. Foster

Faculty Scholarship

Urban residents share access to a number of local resources in which they have a common stake. These resources range from local streets and parks to public spaces to a variety of shared neighborhood amenities. Collectively shared urban resources suffer from the same rivalry and free-riding problems that Garrett Hardin described in his Tragedy of the Commons tale. Scholars have not yet worked up a theory about how this tragedy unfolds in the urban context, particularly in light of existing government regulation and control of common urban resources. This Article argues that the tragedy of the urban commons unfolds during …

Dynamic Control For A Pneumatic Muscle Actuator To Achieve Isokinetic Muscle Strengthening, Kara Lynn Hall

Browse all Theses and Dissertations

A pneumatic muscle actuator (PMA) is a device that mimics behavior of skeletal muscle by contracting and generating force in a nonlinear manner when activated. PMAs have a high power to weight ratio and possess unique characteristics which make them ideal for human interaction. Due to their nonlinear dynamics, PMAs are difficult to control, presenting challenges in system implementation. Despite these challenges, PMAs have great potential as a source of resistance for strength training and rehabilitation. The main goal of this work was to control a PMA for use in isokinetic exercise, potentially benefiting anyone in need of optimal strength …

A Validation Of A Prototype Dry Electrode System For Electroencephalography, Jason Monnin

Browse all Theses and Dissertations

Current physiologically-driven operator cognitive state assessment technology relies primarily on electroencephalographic (EEG) signals. Traditionally, gel-based electrodes have been used; however, the application of gel-based electrodes on the scalp requires expertise and a considerable amount of preparation time. Additionally, discomfort can occur from the abrasion of the scalp during preparation, and the electrolyte will also begin to dry out over extended periods of time. These drawbacks have hindered the transition of operator state assessment technology into an operational environment. QUASAR, Inc., (San Diego, CA) has developed a prototype dry electrode system for electroencephalography that requires minimal preparation. A comparison of the …

Any Pair Of 2d Curves Is Consistent With A 3d Symmetric Interpretation., Tadamasa Sawada, Yunfeng Li, Zygmunt Pizlo

Department of Psychological Sciences Faculty Publications

Symmetry has been shown to be a very effective a priori constraint in solving a 3D shape recovery problem. Symmetry is useful in 3D recovery because it is a form of redundancy. There are, however, some fundamental limits to the effectiveness of symmetry. Specifically, given two arbitrary curves in a single 2D image, one can always find a 3D mirror-symmetric interpretation of these curves under quite general assumptions. The symmetric interpretation is unique under a perspective projection and there is a one parameter family of symmetric interpretations under an orthographic projection. We formally state and prove this observation for the …

Elders’ Attitudes Toward Extending The Healthy Life Span, Victor G. Cicirelli

Department of Psychological Sciences Faculty Publications

Despite continuing debate between anti-aging researchers seeking major life span extension and concerned gerontologists and bioethicists, elders’ views have received little research attention. Study aimed to relate elders’ attitudes toward strong life span extension to psychosocial and background factors. Participants were 109 American elders (65% women) aged 60-99 (M = 77.08, SD = 9.05). Measures included attitudes toward living long and living forever, Desired Age, Death Acceptance, Goal Seeking, Internality, and background variables (age, gender, marital status, education, religion, health). Attitudes were more positive toward an extended life span than living forever (p < .01). In regression analyses, more positive attitudes were related to greater Desired Age, less Death Acceptance, greater Goal Seeking, and greater Internality, and to lower age and non-Christian religious affiliation. Qualitative analyses explored goals for various periods of additional life. Elders’ positive attitudes toward extended life need consideration by experts debating this issue.

Department of Psychological Sciences Faculty Publications

Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed to develop and test an interdisciplinary curriculum for undergraduate and graduate students. The hypothesis was that course curriculum specific to introducing interdisciplinary concepts in cancer prevention would increase student interest in and ability to pursue advanced educational opportunities (e.g., graduate school, medical school). Preliminary results from the evaluation of the first year …

Nubian Identity In The Bronze Age. Patterns Of Cultural And Biological Variation, Michele Buzon

Department of Anthropology Faculty Publications

Th is study uses a bioarchaeological approach to examine the cultural and biological relationships between two groups who lived in ancient Nubia during the Bronze Age, C-Group and Kerma. While archaeological evidence indicates that these groups show many cultural similarities, refl ections of behaviors such as pottery use and mortuary practices suggest that C-Group and Kerma displayed their ethnic diff erences in specifi c situations within a multi-ethnic context. Biological affi nities assessed using cranial measurements suggest a common ancestry with few shape diff erences between the populations. Overall, the Kerma crania are larger than the C-Group crania, which could …

Population Biology Of A Coastal Dune-Dwelling Spider (Arctosa Sanctaerosae) Along The Hurricane Disturbed Northern Gulf Of Mexico Coast, Robert A. Hataway

Electronic Theses and Dissertations

With the continued increase in the number of tourists visiting the Northern Gulf coast in the last century and the resulting development of this coastline the habitat of Arctosa sanctaerosae has become fragmented; and the sprawl of large cities along the coast has further degraded available habitat. In addition to anthropogenic disturbance to this coastal region, hurricanes are an additional and natural perturbation to the ecosystem. This habitat has seen a number of major tropical storms over the last decade and I have sought to explore the impact of habitat destruction and storm-induced disturbance on a species of spider endemic …

Biopharmaceutical Approaches For Improved Drug Delivery Across Ocular Barriers, Ketan Hippalgaonkar

Electronic Theses and Dissertations

The eye is protected from the external environment by various physiological and anatomical barriers. These barriers through there protective actions drastically diminish the ocular bioavailability of drugs. The corneal epithelium acts as a major barrier towards the permeation of hydrophilic agents, whereas poor aqueous solubility presents a formulation challenge for lipophilic compounds. Additionally, P-glycoprotein (P-gp) expressed on the retinal pigmented epithelium (RPE P-gp) limits the penetration of substrates, in therapeutically relevant concentrations, into the back-of-the-eye.

In the present research, use of penetration enhancers (chitosan, benzalkonium chloride (BAK) and ethylenediaminetetraacetic acid (EDTA)) and formulation approaches (cyclodextrins and solid lipid nanoparticles (SLNs)) …

Postglacial Sandy Hill: A Regional Manifestation Of The Gulf Of Maine Archaic Tradition, Benjamin Russell

Electronic Theses and Dissertations

Over twenty years of archaeological excavations at Sandy Hill, in Mashantucket, CT, have provided an incredibly rich assemblage of artifacts. Yet some of the most basic questions about Sandy Hill's Early Archaic inhabitants remain unanswered. This thesis will synthesize the results of major excavations at Sandy Hill by analyzing site morphology, lithics, and hard tissue macrobotanical remains from several radiocarbon dated contexts. Macrobotanical artifacts recovered from Sandy Hill indicate a preference for hazelnut as well as wetland roots and tubers. The lithic assemblage is related to the Gulf of Maine Archaic Tradition and the predominance of quartz flakes technology and …

The Effects Of Chronic Prophylactic Naproxen Sodium On Skeletal Muscle Adaptation To Resistance Exercise In Recreationally-Trained College-Aged Males, Christi Brewer

Electronic Theses and Dissertations

Resistance exercise causes exercise-induced muscle injury (EIMI), triggering an acute local inflammatory response associated with delayed-onset muscle soreness (DOMS). DOMS is characterized by a predictable discomfort and decreased level of muscle performance and is believed to be the product of both mechanical and inflammatory processes. From the latter perspective, non-steroidal anti-inflammatory drugs (NSAIDs) have been investigated for their potential to alleviate DOMS-associated symptoms. Such analgesics exert their effects by blocking the formation of prostaglandins; however, prostaglandins, specifically prostaglandin F 2?, also play an important role in skeletal muscle regeneration. While some have advocated the use of NSAIDs for the relief …

The recently developed mapping prototype is intended to increase accessibility to map data used in class, as well as make it easier to use the data. …

Electric Field Analysis Of Human Breast Tumors For Treatment By Electroporation, Poornima Agoramurthy

Purdue Polytechnic Masters Theses

Breast cancer is a frequently diagnosed disease in women, second only to cancers of the skin. According to the American Cancer Society there were approximately 210,000 new cases of breast cancer estimated in 2010 in the US, 20 % of which resulted in death. With such a high rate of incidence, there is clearly a need for alternate treatments, especially for in-operable tumors and chemo- and radio-resistive patients. Electrochemotherapy, a method by which high intensity, short duration electrical pulses are used to temporarily open pores of cells to enhance uptake of drugs, is gaining popularity in drug delivery for cancer …

Jncml-Like, An Ef-Hand Motif-Containing Gene Seasonally Upregulated In The Transition Zone Of Black Walnut (Juglans Nigra L.), Zhonglian Huang, Priyanka Surana, Daisuke Kihara, Richard Meilan, Keith E. Woeste

Department of Forestry & Natural Resources Faculty Publications

The economic value of a black walnut (Juglans nigra L.) tree is strongly determined by the quality and quantity of darkly colored heartwood in its stem. To understand the regulation of heartwood formation, we analyzed the region of heartwood formation in walnut stems (i.e., the transition zone, TZ) for the expression of 80 ESTs. Semi-quantitative RT-PCR and real-time PCR was performed to detect expression changes of candidate genes in the TZ and sapwood of trees harvested in summer and fall. Results revealed that the transcript of a clone containing two presumed EF-hand motifs was expressed at higher levels in the …

Improving Ammonia Emission Modeling And Inventories By Data Mining And Intelligent Interpretation Of The National Air Emission Monitoring Study Database, Ji-Qin Ni, Erin L. Cortus, Albert J. Heber

School of Agricultural & Biological Engineering Faculty Publications

Ammonia emission is one of the greatest environmental concerns in sustainable agriculture development. Several limitations and fundamental problems associated with the current agricultural ammonia emission modeling and emission inventories have been identified. They were associated with a significant disconnection between field monitoring data and knowledge about the data. Comprehensive field measurement datasets have not been fully exploited for scientific research and emission regulations. This situation can be considerably improved if the currently available data are better interpreted and the new knowledge is applied to update ammonia emission modeling techniques. The world's largest agricultural air quality monitoring database with more than …

Effects Of Alcohol On The Acquisition And Expression Of Fear Potentiated Startle In Mouse Lines Selectively Bred For High And Low Alcohol Preference, Gustavo D. Barrenha, Laran E. Coon, Julia Chester

Department of Psychological Sciences Faculty Publications

Rationale: Anxiety disorders and alcohol-use disorders frequently co-occur in humans perhaps because alcohol relieves anxiety. Studies in humans and rats indicate that alcohol may have greater anxiolytic effects in organisms with increased genetic propensity for high alcohol consumption. Objectives and Methods: The purpose of this study was to investigate the effects of moderate doses of alcohol (0.5, 1.0, 1.5 g/kg) on the acquisition and expression of anxiety-related behavior using a fear-potentiated startle (FPS) procedure. Experiments were conducted in two replicate pairs of mouse lines selectively bred for high- (HAP1 and HAP2) and low- (LAP1 and LAP2) alcohol preference; these lines …

Emergent Identity Matching After Successive Matching Training. I. Reflexivity Or Generalized Identity?, Peter J. Urcuioli

Department of Psychological Sciences Faculty Publications

This research investigated the source of an ostensible reflexivity effect in pigeons reported by Sweeney and Urcuioli (2010). In Experiment 1, pigeons learned two symmetrically reinforced symbolic successive matching tasks (hue-form and form-hue) using red-green and triangle-horizontal line stimuli. They differed in their third concurrently trained baseline task: form-form matching with stimuli appearing in the symbolic tasks (triangle and horizontal) for one group versus hue-hue matching with stimuli not appearing in the symbolic tasks (blue and white) for the other. During subsequent non-reinforced probe tests, all pigeons in the former group and most pigeons in the latter group responded more …

Multiplicatively Interacting Factors Selectively Influencing Parameters In Multiple Response Class Processing And Rate Trees, Richard Schweickert, Zhuangzhuang Xi

Department of Psychological Sciences Faculty Publications

Evidence in many experiments indicates that the processes involved in producing responses are arranged in a tree structure. Evidence often indicates further that an experimental factor, such as item similarity, changes a single parameter, leaving others invariant. In typical studies, a few tree structures are hypothesized a priori, and tested by goodness of fit. With the method of Tree Inference, a tree is constructed by examining the data to see if patterns occur that are predicted when two factors selectively influence different processes (Schweickert & Chen, 2008). The patterns can reveal, for example, whether selectively influenced processes are executed in …

Cardiac Calsequestrin Phosphorylation And Trafficking In The Mammalian Cardiomyocyte, Timothy Mcfarland

Wayne State University Dissertations

Cardiac CSQ (CSQ2) is a multifaceted protein, capable of binding significant quantities of Ca2+ and altering ryanodine receptor activity at the junctional sarcoplasmic reticulum (SR). Little is known about the trafficking of CSQ2 from its unknown site of biosynthesis, which appears to be of importance as its structure changes in a trafficking-dependent manner in various types of heart failure. Through the use of multiple antibodies specific to classic rough ER markers, and with the creation of CSQ-DsRed tetramer fusion protein, we were able to establish a juxtanuclear localization of rough ER in cardiomyocytes. Using fluorescence confocal microscopy, the translocon complex …
