Cbtv: Visualising Case Bases For Similarity Measure Design And Selection, Brian Mac Namee, Sarah Jane Delany

Conference papers

In CBR the design and selection of similarity measures is paramount. Selection can benefit from the use of exploratory visualisation- based techniques in parallel with techniques such as cross-validation ac- curacy comparison. In this paper we present the Case Base Topology Viewer (CBTV) which allows the application of different similarity mea- sures to a case base to be visualised so that system designers can explore the case base and the associated decision boundary space. We show, using a range of datasets and similarity measure types, how the idiosyncrasies of particular similarity measures can be illustrated and compared in CBTV allowing …

Inside The Selection Box: Visualising Active Learning Selection Strategies, Brian Mac Namee, Rong Hu, Sarah Jane Delany

Conference papers

Visualisations can be used to provide developers with insights into the inner workings of interactive machine learning techniques. In active learning, an inherently interactive machine learning technique, the design of selection strategies is the key research question and this paper demonstrates how spring model based visualisations can be used to provide insight into the precise operation of various selection strategies. Using sample datasets, this paper provides detailed examples of the differences between a range of selection strategies.

Returning Home: Women In Post-Conflict Societies, Naomi Cahn, Dina Francesca Haynes, Fionnuala Ní Aoláin

Articles

This paper explores the situation of women returning to their homes and communities after their countries have experienced major conflicts. In that context, it assesses the range of barriers and challenges that women face and offers some thinking to addresses and remedy these complex issues. As countries face the transition process, they can begin to measure the conflict’s impact on the population and the civil infrastructure. Not only have people been displaced from their homes, but, typically, health clinics, schools, roads, businesses, and markets have deteriorated substantially. While the focus is on humanitarian aid in the midst of and during …

Reading Out Of Doors: How Nature Becomes Text And Vice-Versa, Richmond Minor Eustis

LSU Doctoral Dissertations

The tensions between city and country, the artificial and the natural, the real and the fake are at the heart of attempts to render nature in writing. In many such texts, nature—especially wilderness—is the realm of the real, authentic, and pure, while the city is the realm of the artificial and corrupt. This placement of value in nature, members of the critical theory camp tend to counter, is misguided. Any effort to render nature in text is by its “nature” artificial—far more about human values embedded in language itself than about some extra-textual world. With an approach derived from theorists …

The Positive And Negative Effects Of Jealousy On Relationship Quality: A Meta-Analysis, Melissa Ann Newberry

UNF Graduate Theses and Dissertations

Several theories have been posited regarding the role of jealousy on romantic relationships. However, they differ in terms of predictions which when confirmed has resulted in conflicting results. One way to sort out mixed results is to conduct a meta-analysis. Thus, the current investigations conformed to a meta-analysis of studies wherein the association between jealousy and relationship quality had been examined. In the present investigation jealousy had a negative relationship with relationship quality. Type of jealousy experienced moderated the effect on relationships, with anxious jealousy having a stronger negative relationship. Future directions for research in the field of jealousy and …

Short-Selling Prior To Analyst Recommendations, Can Qu

Dissertations and Theses Collection (Open Access)

This paper investigates short-selling five days prior to analyst recommendations by using a complete data set from Reg SHO database during January, 2005 to July, 2007. Empirical tests uncover the evidence that short-sellers significantly increase their short positions prior to negative analyst recommendations, which is consistent with the informed trading hypothesis. This finding is robust to model specification. Further, this paper also examines which of the two competing hypotheses-prediction and tipping-could better explain short-sellers’ informative front-running. The tests indicate that short-sellers use book-to-market ratio as a filter to narrow down their pool of candidates, while market capitalization doesn’t play a …

Magnetic Excitations In The Spinel Compound Liₓ [Mn₁.₉₆ Li₀.₀₄] O₄ (X=0.2,0.6,0.8,1.0 ): How A Classical System Can Mimic Quantum Critical Scaling, Thomas Heitmann, Alexander Schmets, John Gaddy, Jagat Lamsal, Marcus Petrovic, Thomas Vojta, Wouter Montfrooij

Physics Faculty Research & Creative Works

We present neutron-scattering results on the magnetic excitations in the spinel compounds Li_x [Mn_1.96 Li_0.04] O₄ (x=0.2,0.6,0.8,1.0). We show that the dominant excitations below T~70K are determined by Mn ions located in clusters, and that these excitations mimic the dynamic scaling found in quantum critical systems that also harbor magnetic clusters, such as CeRu_0.5 Fe_1.5 Ge₂. We argue that our results for this classical spinel compound suggest that the unusual response at low temperatures as observed in quantum critical systems that have been driven to criticality through substantial chemical doping is …

Security And Performance Analysis For Rfid Protocols, Bing Liang

Dissertations and Theses Collection (Open Access)

Radio Frequency Identification (RFID) is an advanced object identification technology that has already been applied in various industries. However, the insecure nature of the communication channel between readers and tags makes RFID systems vulnerable to various kinds of attacks. In recent years, many new methods have been proposed to improve the security of RFID systems, such as disabling tags, agent management and establishing cryptographic protocols. Among them, we focus on the last approach, which is more economic and convenient in certain cases. The first part of our work is to categorize typical existing RFID protocols according to their security levels. …

Does Corporate Governance Matter, Evidence From Earnings Management Practices In Singapore, Lingxu Hu

Dissertations and Theses Collection (Open Access)

This paper addresses two questions. First, do good corporate governance practices add values to company or does it lead to higher stock returns in Singapore? Second, does poorly governed listed company in SGX tend to manage their earnings by using discretionary accruals? Following the approach of Gompers et al. (2003), we formed two portfolios consisting of well-governed and poorly governed companies. Well governed companies are able to maintain a higher return relative to poorly governed companies. I also look at the firm valuation from the adoption of corporate governance practices. Our result shows a positive relationship between firm valuation and …

Organizational Slack, International Expansion And Firm Profitability, Anran Liu

Dissertations and Theses Collection (Open Access)

International expansion is a viable growth strategy for firms operating in an increasingly competitive business environment. Understanding the relationship between international expansion and firm performance has been a significant concern for theory development in the strategy and international business literature. The extant literature, however, has paid insufficient attention to the tradeoff between firm growth and profitability that may imply the existence of an optimal rate of growth. Drawing from the Penrosian perspective that emphasizes the role of resources in firm growth, this study investigates whether and how firm slack resources affect the tradeoff between international expansion and profitability. Specifically, this …

Impedance Spectroscopy Of Batio₃ Cubes Suspended In Lossy Liquids As A Physical Model Of Two-Phase System, Piotr Z. Jasinski, Vladimir Petrovsky, Fatih Dogan

Materials Science and Engineering Faculty Research & Creative Works

Impedance spectroscopy techniques were used for analysis of the physical model in a two-phase system toward determining of dielectric constant of dielectric particles suspended in liquids at various solids loading (volume fraction) levels. Model experimental studies were conducted using BaTiO3 as a dielectric material that was prepared as small cubes of uniform size (2×2×1 mm). Barium titanate (BT) cubes having a dielectric constant of 3850 were immersed in liquids of low dielectric constant and moderate electrical conductivity. Measured impedance spectra consisted of two semicircles, which were fitted for (R∥C)(R∥C) equivalent circuit. The parameters obtained from fitting were compared with the …

Effect Of Phosphorus On Cleavage Fracture In Κ-Carbide, N. I. Medvedeva, Ryan A. Howell, David C. Van Aken, Julia E. Medvedeva

Materials Science and Engineering Faculty Research & Creative Works

To understand the origin of cleavage fracture which dominates in Fe(Mn)-Al-C alloys at a high phosphorus concentration, we performed first-principles study of the phosphorus effect on ideal cleavage energy and critical stress in κ-carbide, Fe₃ AlC, a precipitate in the austenitic alloys. We find that phosphorus has higher solubility in Fe₃ AlC than in γ-Fe and sharply reduces the cleavage characteristics of κ-carbide. We show that strong anisotropy of the Fe-P bonds in Fe₃ (Al,P) C under tensile stress, leads to the appearance of large structural voids and may facilitate crack nucleation.

An Analysis Of Strength And Ductility Of Ultrafine Grained Al Alloys, R. Kapoor, P. S. De, R. S. Mishra

Materials Science and Engineering Faculty Research & Creative Works

This paper brings together and compares data of various ultrafine grained (UFG) Al alloys processed through different routes. in general, the trend of decreasing ductility with increasing strength was observed for the UFG alloys. as compared to the coarse grained (CG) alloys, the UFG alloys show a lower ductility, a lower extent of work-hardening and a lower uniform elongation. Unlike the CG alloys, which show a large fraction of uniform to total elongation, in UFG alloys this fraction varies with processing technique. It is shown here that aging of some UFG Al alloys improves ductility. Further, it is shown that …

Influence Of Fraction Of High Angle Boundaries On The Mechanical Behavior Of An Ultrafine Grained Al-Mg Alloy, R. Kapoor, N. Kumar, R. S. Mishra, C. S. Huskamp, K. K. Sankaran

Materials Science and Engineering Faculty Research & Creative Works

The mechanical behavior of ultrafine grained AA5052 processed through different techniques-rolled, annealed, friction stir processed (FSP) and equal channel angular pressed (ECAP)-were compared and correlated with microstructure. the microstructure was characterized using electron back scattered diffraction to obtain the boundary spacing, the fraction of high angle boundaries and to estimate the dislocation density from local misorientations. Both FSP and ECAP conditions had ultrafine boundary spacing, but the fraction of high angle boundaries was larger for the FSP condition. Tensile deformation carried out at 297K, and 10-3s-1 showed a lower work-hardening rate and recovery rate for FSP as compared to the …

Continued Viability: A Review Of The Life Sciences Library At Indiana University In A Time Of Institutional Change And Proposed Branch Library Downsizing, J B. Hill, Brian Winterman

Faculty Scholarship

There has been a growing realization that academic libraries need to change to serve a new generation of learners and researchers. Efforts to enhance the "Main Library" on campus with extended hours, coffee shops, and information commons have created modern, user-friendly environments that support changing student needs and expectations.  Generally fewer resources have been given to upgrading smaller branch libraries. The need to modernize older spaces along with the availability of electronic collections, campus demands for classroom/lab space and financial pressures on libraries have prompted a rethinking of the role of branch libraries. Actively pursuing initiatives to re-envision library spaces …

Development Of A Unified Approach (An Index) To Study The Particulate, Carbon Monoxide Emissions And The Combustion Efficiency Using Field And Laboratory Investigations, Vidhi Singhal

All Theses and Dissertations (ETDs)

About one-third of the world’s population uses biomass and other renewable sources of fuel for cooking and other heating purposes. The Biomass is not burnt efficiently which results in the release of pollutants which are the products of incomplete combustion. Previously, studies have been done to study the PM2.5, CO, methane and non methane compounds to study the dose exposure relationships of the cookstoves. One major drawback in these studies was that they didn’t use the surface area of the particles emitted from the cookstoves. As it has been established in the previous studies, the ultrafine particles have more surface …

Prediction Of Optical Properties Of Plasmonic Composites: Applications To Solar Energy Harvesting, Satvik Wani

All Theses and Dissertations (ETDs)

The finite difference time domain method was used to simulate the optical response of plasmonic composites with one and two nanoscale spherical metallic inclusion(s): Ag/Cu in Air/SiO2) with various diameters and compositions. Fair agreement was found between simulation and effective medium theories for binary and ternary composites. Responses of ternary Ag/Cu/SiO2 composites with various Ag:Cu ratios were found to be in fair agreement with the experimental data obtained from literature. Experiments with photosynthetic microalga Chlamydomonas Reinhardtii and Cyanothece showed that the wavelength specific backscattering in the blue region of the spectrum from an Ag nanoparticle suspension could promote microalgal growth …

Macrophage Responses To Cf Pathogens: Jnkmap Kinase Signaling By Burkholderia Cepacia Complex Lipopolysaccharide, Suzanne Mckeon, Siobhan Mcclean, Máire Callaghan

Articles

Chronic bacterial colonization of the airways with opportunistic pathogens is the primary cause of morbidity and mortality in cystic fibrosis (CF) patients. Burkholderia cepacia complex (Bcc) organisms pose a particular challenge in CF lung disease, due in part to their ability to trigger a fulminant pneumonia. This study compares the U937 macrophage response to two Bcc species, B. cenocepacia and Burkholderia multivorans, against Pseudomonas aeruginosa and Staphylococcus aureus. The two Bcc strains demonstrated higher levels of U937 macrophage internalization compared with both P. aeruginosa and S. aureus. Both the Bcc strains also stimulated significantly greater levels of tumor necrosis factor-a …

The Gospel According To Moses And Elijah, Roy E. Gane

Andrews University Seminary Studies (AUSS)

Jesus’ gospel culminates the deliverance messages of Moses and Elijah and points to our role: If we love Christ a lot because he has forgiven us a lot (Luke 7:40-47), we will find no greater joy than reconciling precious people to one another and to him before the great day of his return.

Regulatory Blowout: How Regulatory Failures Made The Bp Disaster Possible, And How The System Can Be Fixed To Avoid A Recurrence, Robert L. Glicksman

GW Law Faculty Publications & Other Works

The BP oil spill in the Gulf of Mexico is destined to take its place as one of the greatest environmental disasters in the history of the United States, or for that matter, of the entire planet. Like so many other disasters on that list, it was entirely preventable.

BP must shoulder its share of the blame, of course. Similarly, the Minerals Management Service (MMS) – since reorganized and rebranded – has come under much deserved criticism for its failure to rein in BP’s avaricious approach to drilling even where it was unable to respond to a worst-case scenario in …
