The Evaluation And Implementation Of Magnetic Fields For Large Strain Uniaxial And Biaxial Cyclic Testing Of Magnetorheological Elastomers., Dave Gorman, Niall Murphy, Ray Ekins, Stephen Jerrams

Articles

Magnetorheological Elastomers (MREs) are “smart” materials whose physical properties are altered by the application of magnetic fields. In previous studies the properties of MREs have been evaluated under a variety of conditions, however little attention has been paid to the recording and reporting of the magnetic fields used in these tests [1]. Currently there is no standard accepted method for specifying the magnetic field applied during MRE testing. This study presents a detailed map of a magnetic field applied during MRE tests as well as providing the first comparative results for uniaxial and biaxial testing under high strain fatigue test …

An Evaluation Of Factors Which Can Affect The Implementation Of A Health Promotion Programme Under The Schools For Health In Europe Framework, Annemarie Bennett, Cara Cunningham, Charlotte Johnston Molloy

Articles

The Health Promoting Schools concept helps schools to promote health in a sustainable and long-term fashion. However, developing the capacity to promote health in this way can be challenging when a busy teaching curriculum must be fulfilled. This study aimed to identify factors which affect the acceptability of health promotion programmes to the everyday school environment.

Semi-structured qualitative interviews were audio-taped with primary school teachers in one Irish county and transcribed verbatim. The resulting transcripts were analysed using content analysis.

Thirty-one teachers were interviewed. The factors which may adversely affect the acceptability of health promotion programmes include the: attitude of …

Case Study On Performance And Acceptance Of Computer-Aided Assessment, Bianca Schoen-Phelan, Brian Keegan

Articles

Computer aided assessment (CAA) comprises a set of assessment techniques that are conducted on a computer. These forms of assessment may be purely online or network based or single, stand-alone device based. The device may be a desktop computer or include the use of mobile devices. This paper investigates if CAA leads to improved performance and satisfaction. The student cohort that participated in this pilot study came from a degree in computer science. A preliminary investigation was performed by executing two continuous assessments with one cohort of four students in an advanced databases class. One of the assessments was purely …

Quantification Of Hemodynamic Pulse Wave Velocity Based On A Thick Wall Multi-Layer Model For Blood Vessels, Jeffrey S. Lillie, Alexander S. Liberson, David A. Borkholder

Articles

Pulse wave velocity (PWV) is an important index of arterial hemodynamics, which lays the foundation for continuous, noninvasive blood pressure automated monitoring. The goal of this paper is to examine the accuracy of PWV prediction based on a traditional homogeneous structural model for thin-walled arterial segments. In reality arteries are described as composite heterogeneous hyperelastic structures, where the thickness dimension cannot be considered small compared to the cross section size. In this paper we present a hemodynamic fluid - structure interaction model accounting for the variation of geometry and material properties in a radial direction. The model is suitable to …

Antibacterial Derivatives Of Marine Algae: An Overview Of Pharmacological Mechanisms And Applications, Emer Shannon, Nissreen Abu-Ghannam

Articles

The marine environment is home to a taxonomically diverse ecosystem. Organisms such as algae, molluscs, sponges, corals, and tunicates have evolved to survive the high concentrations of infectious and surface-fouling bacteria that are indigenous to ocean waters. Both macroalgae (seaweeds) and microalgae (diatoms) contain pharmacologically active compounds such as phlorotannins, fatty acids, polysaccharides, peptides, and terpenes which combat bacterial invasion. The resistance of pathogenic bacteria to existing antibiotics has become a global epidemic. Marine algae derivatives have shown promise as candidates in novel, antibacterial drug discovery. The efficacy of these compounds, their mechanism of action, applications as antibiotics, disinfectants, and …

Theoretical Modeling Of The Effect Of Polymer Chain Immobilization Rates On Holographic Recording In Photopolymers, Dana Mackey, Paul O'Reilly, Izabela Naydenova

Articles

This paper introduces an improved mathematical model for holographic grating formation in an acrylamide-based photopolymer, which consists of partial differential equations derived from physical laws. The model is based on the two-way diffusion theory of \cite{izabela}, which assumes short polymer chains are free to diffuse, and generalizes a similar model presented in \cite{josab} by introducing an immobilization rate governed by chain growth and cross-linking. Numerical simulations were carried out in order to investigate the behaviour of the photopolymer system for short and long exposures, with particular emphasis on the effect of recording parameters (such as illumination frequency and intensity), as …

Framing Professional Programs Within Development Projects: Driving Longer Term Recognition And Integration, Diane Wallace, James Loughman, Kovin Naidoo

Articles

Background: Optometry has, over the past ten years, emerged as a profession strategically positioned to address the burden of uncorrected refractive error in developing countries. Estimates suggest that 285 million people in the world are needlessly visually impaired, mainly due to the lack of trained eye health professionals in the developing world. Development initiatives in eye care have therefore moved away from vertical, service delivery approaches to supporting the establishment of more sustainable, locally owned training programs. This research is based on one the evaluation of one such initiative known as the Mozambique Eyecare Project.

Methods: This study followed a …

Profit-Shifting Structures And Unexpected Partnership Status, Jeffrey M. Kadet, David Koontz

Articles

Many U.S.- and foreign-based MNCs that have implemented carefully researched tax strategies to reduce their income taxes are coming under increased scrutiny. Most MNC tax strategies involve businesses they conduct worldwide, but which are managed from the U.S. These strategies have several factors in common:

(i) Companies established in tax havens or otherwise structured to attract little if any tax;

(ii) Intercompany agreements placing commercial risk and intangibles in such companies, thereby shifting profits to such companies;

(iii) Conduct of centralized activities and functions in the U.S. (in addition to group senior management), which are integral to and which critically …

Photocatalytic Properties Of G-C3n4–Tio2 Heterojunctions Under Uv And Visible Light Conditions, Rachel Fagan, Declan Mccormack, Steven J. Hinder, Suresh Pillai

Articles

Graphitic carbon nitride (g-C3N4) and titanium dioxide (TiO2) were chosen as a model system to investigate photocatalytic abilities of heterojunction system under UV and visible light conditions. The use of g-C3N4 has been shown to be effective in the reduction in recombination through the interaction between the two interfaces of TiO2 andg-C3N4. A simple method of preparing g-C3N4 through the pyrolysis of melamine was employed, which was then added to undoped TiO2 material to form the g-C3N4–TiO2 system. These materials were then fully characterized by X-ray diffraction (XRD), Brunauer Emmett Teller (BET), and various spectroscopic techniques including Raman, X-ray photoelectron …

The Use Of Specialized Cybercrime Policing Units: An Organizational Analysis, Dale Willits, Jeffrey Nowacki

Articles

Given the increased focus and importance of cybercrime, some police agencies have turned to the use of specialized cybercrime policing units. Research has yet to examine the how frequently these units are used in policing, nor has research examined the types of agencies most likely to use these units. The current research, drawing on contingency theory, institutional theory, and Maguire’s theory of police organizational structure, uses four waves of Law Enforcement Management and Administrative Survey data to provide a descriptive analysis of specialized cybercrime units with a focus on identifying organizational correlates, environmental pressures, and the role of time. Trend …

An Intersectional Approach To Race/Ethnicity, Sex, And Age Disparity In Federal Sentencing Outcomes: An Examination Of Policy Across Time Periods, Jeffrey Nowacki

Articles

Approaches to intersectionality stress the importance of recognizing multiple, intersecting inequalities. As such, recent sentencing research has examined the changing role of extra-legal characteristics on United States federal sentencing outcomes in the aftermath of recent policy changes (e.g., United States v. Booker), but scholarship has less often examined these characteristics at the intersections of race/ethnicity, gender, and, especially age. This article uses an intersectional approach to examine the influence of these characteristics net of legally-relevant characteristics. Using ordinary-least squares regression procedures, the author examines the role of the joint effects of extra-legal variables on sentence length decisions across four distinct …

Human Mitochondrial Dna Replication Machinery And Disease., Matthew J Young, William C Copeland

Articles

The human mitochondrial genome is replicated by DNA polymerase γ in concert with key components of the mitochondrial DNA (mtDNA) replication machinery. Defects in mtDNA replication or nucleotide metabolism cause deletions, point mutations, or depletion of mtDNA. The resulting loss of cellular respiration ultimately induces mitochondrial genetic diseases, including mtDNA depletion syndromes (MDS) such as Alpers or early infantile hepatocerebral syndromes, and mtDNA deletion disorders such as progressive external ophthalmoplegia, ataxia-neuropathy, or mitochondrial neurogastrointestinal encephalomyopathy. Here we review the current literature regarding human mtDNA replication and heritable disorders caused by genetic changes of the POLG, POLG2, Twinkle, RNASEH1, DNA2, and …

Vegetation Response To Piñon And Juniper Tree Shredding, Jordan Bybee, Bruce A. Roundy, Kert R. Young, April Hulet, Darrell B. Roundy, Leann Crook, Zachary Aanderud, Dennis L. Eggett, Nathan L. Cline

Articles

Piñon (Pinus spp.) and juniper (Juniperus spp.) expansion and infilling in sagebrush (Artemisia L.) steppe communities can lead to high-severity fire and annual weed dominance. To determine vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding, we measured cover for shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah. We used mixed model analysis of covariance to determine significant differences among ecological site type (expansion and tree climax) and treatments across a range of pretreatment tree cover as the covariate. Although expansion and tree climax …

Evaluation Of Cytotoxicity Profile And Intracellular Localisation Of Doxorubicin-Loaded Chitosan Nanoparticles, Gabriele Dadalt Souto, Zeineb Farhane, Esen Efeoglu, Alan Casey, Jennifer Mcintyre, Hugh Byrne

Articles

In the emerging field of nanomedicine, targeted delivery of nanoparticle encapsulated active pharmaceutical ingredients (API) is seen as a potential significant development, promising improved pharmacokinetics and reduced side effects. In this context, understanding the cellular uptake of the nanoparticles and subsequent subcellular distribution of the API is of critical importance. Doxorubicin (DOX) was encapsulated within chitosan nanoparticles to investigate its intracellular delivery in A549 cells in vitro. Unloaded (CS-TPP) and doxorubicin-loaded (DOX-CS-TPP) chitosan nanoparticles were characterised for size (473±41 nm), polydispersity index (0.3±0.2), zeta potential (34±4 mV), drug content (76±7 µM) and encapsulation efficiency (95±1%). The cytotoxic response to …

Same-Sex Spouses Lost In Translation? How To Interpret “Spouse” In The E.U. Family Migration Directives, Scott Titshaw

Articles

This Article analyzes the word “spouse” in the European Union’s Family Migration Directives in detail, focusing on the treatment of married bi-national same-sex couples. Through these directives, the European Union exercises significant authority over family-based immigration and internal migration, expressly providing immigration rights to the “spouses” of E.U. citizens and legal residents. However, family law, including the familial status of “spouses” is governed by individual E.U. member states. While a growing number of member states authorize same-sex marriage, the majority still do not. The E.U., therefore, must determine how to treat migrating couples who are legal spouses in one member …

The Evolution Of Strategic Sophistication, Nikolaus Robalino, Arthur Robson

Articles

This paper investigates the evolutionary foundation for our ability to attribute preferences to others, an ability that is central to conventional game theory. We argue here that learning others’ preferences allows individuals to efficiently modify their behavior in strategic environments with a persistent element of novelty. Agents with the ability to learn have a sharp, unambiguous advantage over those who are less sophisticated because the former agents extrapolate to novel circumstances information about opponents’ preferences that was learned previously. This advantage holds even with a suitably small cost to reflect the additional cognitive complexity involved.

Thirty-Six-Point Perpetua: John Updike's Personal Essays In The Later Years, Laurence W. Mazzeno, Sue Norton

Articles

This article considers the central preoccupations and modus operandi of the American writer John Updike as an essayist with personal, autobiographical intent. Best known in the American canon for his many works of fiction, he produced nonfiction in equal measure over the course of his lengthy career. His far-ranging critical reviews and topical, discursive writings have occupied pride of place in the most prominent periodicals of our times and have garnered much critical and popular attention. Yet his specifically self-referential essays, especially those composed in the final years of his life, deserve closer notice for the ways in which they …

Effects Of Deposition Process On Poly-Si Microscale Energy Harvesting Systems: A Simulation Study, Elif Selin Mungan, Chao Lu, Chih-Hisang Ho, Kaushik Roy

Articles

In this paper, the feasibility of a low-temperature polysilicon (LTPS) microscale energy harvester for a wireless sensor node is investigated. For that purpose, two device-level models for the LTPS solar cell and thin-film transistors are proposed and employed in system-level evaluation of an energy harvesting system. The results of our analysis indicate that: 1) the maximum power operating point for the solar cell is different when connected to a lossy power converter; 2) increasing the average grain size of the LTPS film can reduce the circuit area by 20 times, while increasing the output power by 6%; and 3) the …

A Comprehensive Theory Of Civil Settlement, J. J. Prescott, Kathryn E. Spier

Articles

A settlement is an agreement between parties to a dispute. In everyday parlance and in academic scholarship, settlement is juxtaposed with trial or some other method of dispute resolution in which a third-party factfinder ultimately picks a winner and announces a score. The “trial versus settlement” trope, however, represents a false choice; viewing settlement solely as a dispute-ending alternative to a costly trial leads to a narrow understanding of how dispute resolution should and often does work. In this Article, we describe and defend a much richer concept of settlement, amounting in effect to a continuum of possible agreements between …

Big Data, Patents, And The Future Of Medicine, W. Nicholson Price Ii

Articles

Big data has tremendous potential to improve health care. Unfortunately, intellectual property law isn’t ready to support that leap. In the next wave of data- driven medicine, black-box medicine, researchers use sophisticated algorithms to examine huge troves of health data, finding complex, implicit relationships and making individualized assessments for patients. Black-box medicine offers potentially immense benefits, but also requires substantial high investment. Firms must develop new datasets, models, and validations, which are all nonrivalrous information goods with significant spillovers, requiring incentives for welfare-optimizing investment. Current intellectual property law fails to provide adequate incentives for black- box medicine. The Supreme Court …

Justice Kennedy And The Fisher Revisit: Will The Irrelevant Prove Decisive?, Richard O. Lempert

Articles

Most Court watchers expect Justice Kennedy to cast the deciding vote when the Supreme Court hands down its decision in this term’s installment of Fisher v. University of Texas at Austin or, as it is colloquially titled, Fisher II. What divides observers is not whose vote will be crucial, but the law that vote will make. At one extreme, Justice Kennedy could vote to uphold the Fifth Circuit’s reaffirmation of its earlier decision. When the case was heard, this would almost certainly have meant affirming the circuit court’s decision by an equally divided Court. (Justice Kagan, an almost certain supporter …

Gold Nanoprisms As A Hybrid In Vivo Cancer Heranostic Platform For In Situ Photoacoustic Imaging, Angiography, And Localized Hyperthermia, Chenchen Bao, Joao Conde, Fei Pan, Chao Li, Chunlei Zhang, Furong Tian, Shujing Liang, Jesus M. De La Fuente, Daxiang Cui

Articles

The development of high-resolution nanosized photoacoustic contrast agents is an exciting yet challenging technological advance. Herein, antibody (breast cancer-associated antigen 1 (Brcaa1) monoclonal antibody)- and peptide (RGD)- functionalized gold nanoprisms (AuNprs) were used as a combinatorial methodology for in situ photoacoustic imaging, angiography, and localized hyperthermia using orthotopic and subcutaneous murine gastric carcinoma models. RGD-conjugated PEGylated AuNprs are available for tumor angiography, and Brcaa1 monoclonal antibody-conjugated PEGylated AuNprs are used for targeting and for in situ imaging of gastric carcinoma in orthotopic tumor models. In situ photoacoustic imaging allowed for anatomical and functional imaging at the tumor site. In vivo …

A Cross-Cultural Examination Of Preferences For Work Attributes, Melissa S. Woodard, Jane K. Miller, Daniel Miller, Kirk D. Silvernail, Chun Guo, Sudhir Nair, Mehmet Devrim Aydin, Ana Helosia Da Costa Lemos, Paul Donnelly, Vilmante Kumpikaite, Robert Marx, Linda M. Peters

Articles

Purpose – The purpose of this paper is to examine the relationship between individual- and country-level values and preferences for job/organizational attributes. Design/methodology/approach – Survey data were collected from 475 full-time employees (average of nine years work experience, and three years in a managerial position) enrolled in part-time MBA programs in seven countries. Findings – Preference for a harmonious workplace is positively related to horizontal collectivism, whereas preference for remuneration/advancement is positively related to vertical individualism. The authors also find a positive relationship between preference for meaningful work and horizontal individualism, and between preference for employer prestige and social adjustment …

The Enigma Of Wynne, Edward A. Zelinsky

Articles

The five-justice Wynne majority used that case to make a major statement about the dormant Commerce Clause. In many respects, Wynne is an enigma that perpetuates an inherent problem of the Courts dormant Commerce Clause doctrine: the Court declares some ill-defined taxes as unconstitutionally discriminatory because they encourage in-state investment, while other economically equivalent taxes and government programs that similarly encourage intrastate economic activity are apparently acceptable under the dormant Commerce Clause.

Wynne is thus more important than the immediate situation it addresses, and will have consequences beyond the immediate circumstances it addresses. A decision as enigmatic as it is …
