Preliminary factor analysis of the O’Kelly Women Beliefs Scale in a US sample
Arturo Heman Contreras,Leonor Lega,Monica OKelly,Mark J. Friedman
Universitas Psychologica , 2012,
Abstract: Using a Rational Emotive Behavior Therapy framework, the O’Kelly Women Beliefs Scale (O’Kelly, in press) was originally constructed in Australia to measure sex-role beliefs women may develop through sex-role stereotyping. Factor analysis of the 92 original items showed that 64 items loaded into a single component that accounted for 18.2% of the variance in a sample of 974 Australian women. The present exploratory study examined the psychometric properties of the OWBS in a sample of 202 women born and living in the US. A varimax rotation with cutoff eigenvalues of 3, showed that 37 items loaded into 3 components which accounted for 58.48% of the variance. The items were subsequently grouped into two factors: Ir- rationality, with a total of 27 items was created by merging component 1 and 3 (Pearson’s r = 0.8 between them), and Rationality, with the 10 items from component 2. Analyses indicated a Cronbach’s alpha of 0.91 for Fac- tor 1, and a Cronbach’s alpha 0.74 for Factor 2. Results indicate that this version of the instrument may be used to evaluate both the rational and irrational content of sex-role beliefs of women born in the US.
Cross Cultural Instruction: An Instructional Design Case
Monica W. Tracey,Kelly L. Unger
International Journal of Designs for Learning , 2010,
Abstract: In an authentic example of linking design and development with learning and performance, an international real estate development firm defined a problem; implementing a cleaning system in the largest mall in the world with a cross-cultural unskilled work force in Dubai, UAE. Partnering with a university instructional design team employing a rapid prototyping methodology and the constructivist ID approach, Layers of Negotiation Model, a comprehensive curriculum was designed. This article describes the project background, initial design, the ID team's work in Dubai, illustrates the product, and summarizes the design experience.
Exploring the Relationship between Obstetrical Nurses’ Work and Pregnancy Outcomes  [PDF]
Jo Watson, Monica Nicholson, Kelly Dobbin, Karen Fleming, Julia M. K. Alleyne
Open Journal of Nursing (OJN) , 2016, DOI: 10.4236/ojn.2016.69080
Abstract: The Registered Nurses Association of Ontario Healthy Work Environments Best Practice Guideline recommends that employers promote safe, healthy workplaces. Healthy workplaces include addressing the unique needs of nurses who work while pregnant. The purpose of this descriptive study, summarizing information from 120 pregnancies reported by 95 nurses, was to determine if the workload of obstetrical nurses was associated with negative pregnancy outcomes, including preterm delivery and birth weight. Full-time obstetrical nursing work is a predictor of reduced birth weight, but not of preterm birth when compared to outcomes of obstetrical nurses working part time. One third of nurses reported pregnancy complications and most nurses experienced work-related and personal stress. Further research evaluating work modifications during pregnancy is indicated to improve birth outcomes.

Matthew Knauss, Felicia Tolea, Mihaela Valeanu, Lucian Diamandescu, Richard Trotta, Kelly Wood, Agnieszka Grabias, Monica Sorescu
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2018, DOI: 10.4236/jmmce.2018.66042
Abstract: xMoO2-(1-x)α-Fe2O3 nanoparticle system with molarities x = 0.1, 0.3, 0.5 and 0.7 was successfully synthesized by mechanochemical activation of MoO2 and α-Fe2O3 mixtures for 0 - 12 hours of ball milling time. X-ray powder diffraction (XRD), Mössbauer spectroscopy and magnetic measurements were used to study the phase evolution of the molybdenum dioxide-hematite nanoparticle system under the mechanochemical activation process. Rietveld refinement of the XRD patterns yielded the values of the crystallite size and lattice parameters as function of milling times and indicated the presence of Mo-substituted hematite and Fe-doped molybdenum dioxide at long milling times. The Mössbauer studies yielded the magnetic hyperfine fields and the relative abundance of a quadrupole-split doublet as function of the milling time for all molar concentrations involved. Recoilless fraction was determined using our dual absorber method and was found to decrease with increasing ball milling time. Magnetic measurements recorded at 5 and 300 K in an applied magnetic field of 50,000 Oe showed the magnetic properties in the antiferromagnetic and canted ferromagnetic states. The Morin transformation was evidenced by zero-field cooling-field cooling (ZFC-FC) measurements in a magnetic field of 200 Oe.
The terrestrial evolution of metabolism and life – by the numbers
Gregory C O'Kelly
Theoretical Biology and Medical Modelling , 2009, DOI: 10.1186/1742-4682-6-17
Abstract: If the equation includes a term for efficiency in the exponent, thereby ruling out thermogenesis as part of metabolism, its heuristic power is greatly amplified, and testable deductive inferences are generated. If metabolic rate is measured in watts and metabolic efficiency is a redox-coupling ratio, then the equation is essentially about the energy storage capacity of organic molecules. The equation is entirely about the essentials of all life: water, salt, organic molecules, and energy. The water and salt provide an electrochemical salt bridge for the transmission of energy into and through the organic components. The equation, when graphed, treats the organic structure as battery-like, and relates its recharge rate and electrical properties to its longevity.The equation models the longevity-extending effects of caloric restriction, and shows where those effects wane. It models the immortality of some types of cells, and supports the argument for the origin of life being at submarine volcanic vents and black smokers. It clarifies how early life had to change to survive drifting to the surface, and what drove mutations in its ascent. It does not deal with cause and effect; it deals with variables in the essentials of all life, and treats life as an epiphenomenon of those variables. The equation describes how battery discharge into the body can increase muscle mass, promote fitness, and extend life span, among other issues.This paper is a prelude to a rigorous mathematical exploration of the physics of organic batteries and their significance for understanding many phenomena of life, which will be presented in another article.The second law of thermodynamics states that in a closed system, one to which additional energy is not available, the tendency over time will be for that energy to be equally distributed throughout the system such that net energy transmission between elements of that system ceases. This is called heat death. Open systems, in contrast, are reple

Meeting Their Fullest Potential: The Beliefs and Teaching of a Culturally Relevant Science Teacher  [PDF]
Charlease P. Kelly-Jackson, Tambra O. Jackson
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.24059
Abstract: As elementary and middle school children of color continue to score poorly on science standardized tests, culturally relevant teaching has been shown to be an effective approach to addressing the social and academic needs of students from diverse backgrounds. In this article, we illustrate how the theory of culturally relevant pedagogy is embraced in the teaching beliefs of a sixth grade science teacher in a rural, low socioeconomic, predominantly African American school. The findings from a qualitative case study reveal beliefs and teaching practices consistent with three major tenets of culturally relevant pedagogy: conceptions of self and students; social relations; and perceptions of knowledge (Ladson-Billings, 2009). This study builds upon the culturally relevant pedagogy knowledge base by illustrating the tenets of this theory in the beliefs and teaching practices of a sixth grade science teacher.
Extending knowledge of Escherichia coli metabolism by modeling and experiment
Eberhard O Voit, Monica Riley
Genome Biology , 2003, DOI: 10.1186/gb-2003-4-11-235
Abstract: It has become a platitude of the post-genomic era that a deluge of data is being produced and awaits both computational/mathematical analysis and experimental verification. There is no reason to argue with this observation, yet it leads to two immediate follow-up questions. First, has the genomic era come to an end already? And second, what types of mathematical and computational models would be most beneficial for dealing with the rich streams of data? Two recent articles, by Reed et al. [1] and Corbin et al. [2], answer the first question in the negative: there is still a lot of genomic research to be done. These two articles show that, even for one of the best studied of organisms, Escherichia coli, there are still very many genes for which we know little beyond their sequence and location. We don't know what their functions are, exactly which genes are actively functioning at any one time, and to what degree some might even be entirely dispensable. The experimental approach proposed by Corbin et al. [2] sheds light on some of these issues with a combination of two methods, one for measuring gene expression and one for detecting proteins in E. coli cells. In contrast, Reed et al. [1] address the two questions with a novel and interesting application of mathematical modeling.The combination of the two papers is intriguing, because both have the same purpose - annotating gene function and learning more about intermediary metabolism - yet the two use very different approaches to accomplish their common goal. This independence of approaches may be useful for comparisons or for mutual complementation of results, and could aid the community in answering questions about the reliability of separate approaches to interpreting genomic information.To assign metabolic functions to unknown genes, Reed et al. [1] use a method that is based on a combination of mathematical modeling and data mining. The authors use the available literature and database information to construct a
Coping with "traditions": the analysis of East-Timorese nation building from the perspective of a certain anthropology made in Brazil
Silva, Kelly;Simi?o, Daniel;
Vibrant: Virtual Brazilian Anthropology , 2012, DOI: 10.1590/S1809-43412012000100013
Abstract: the purpose of this essay is twofold. first, we explore the extent to which certain practices in urban east timor perceived as traditional may be associated to different ways of negotiating individual and collective identities while uncovering dilemmas of nation building and state formation. to this effect, we take into account specific variations of current practices in marriage negotiations in dili, considering their structural role in forging local sociality. based on repeated field trips, we contend that different discourses about "tradition" can be related to different ways in which one is positioned vis-à-vis the multiple symbolic elements available in current east-timorese public spaces. as these different meanings of "tradition" also challenge public policies, their application may uncover different ideas about what a nation ought to be. second, we ponder on the extent to which our specific focus is due to our background as brazilian anthropologists, built around our dialogue with certain anthropological lines of analysis in brazil, particularly those related to interethnic friction and the place of indigenous peoples in the national imagination, as well as those dedicated to such themes as cultural diversity, citizenship, and public policies in urban brazil.
Wellen′s syndrome: An ominous EKG pattern
Mead Nicole,O′Keefe Kelly
Journal of Emergencies, Trauma and Shock , 2009,
Abstract: Wellen′s syndrome is a characteristic T-wave on an electrocardiogram during a pain-free period in a patient with intermittent chest pain. This finding suggests a high-degree stenosis of the proximal left anterior descending (LAD) coronary artery that will soon result in an acute anterior wall myocardial infarction (MI) if the patient is not urgently catheterized and the occlusion opened. This case report discusses a young male patient with no known cardiac disease with an EKG that demonstrates the classic Wellen′s T-waves. He was urgently taken to cardiac catheterization and his 95% proximal LAD stenosis was reduced via drug-eluding stent. Through knowledge of Wellen′s T-waves, more anterior wall MIs can be prevented.
