External Representations in the Teaching and Learning of Introductory Chemistry  [PDF]
James R. Cox, Bethany W. Jones
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.25067
Abstract: This manuscript describes the role that external representations, such as diagrams and sketches, can play in organizing and learning concepts presented in a one-semester chemistry course (general, organic and biochemistry) designed for nursing students. Although external representations are typically found in chemistry textbooks and instructor-drawn notes, students are usually not taught or prompted to use various types of external representations to promote learning. Representations created by an instructor and a student are discussed to highlight effective ways to foster student participation in creating various diagrams. In addition, a student provides a perspective on the educational value of creating external representations and the roles of visual thinking and creativity in learning introductory chemistry. Although the model for this approach has been an introductory chemistry course, this approach can be widely applied across disciplines.
Comparing the Sensitivity of the MMPI-2 Clinical Scales and the MMPI-RC Scales to Clients Rated as Psychotic, Borderline or Neurotic on the Psychodiagnostic Chart  [PDF]
Robert M. Gordon, Ronald W. Stoffey, Bethany L. Perkins
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.49A1003

The purpose of this study was to assess the differences between the MMPI-2 and the MMPI-RC scales in sensitivity to levels of psychopathology. Ninety-eight clients from forensic, disability and psychotherapy evaluations were evaluated on the MMPI-2 and RC scales and rated for personality organization (neurotic, borderline or psychotic) on the Psychodiagnostic Chart. The results over-all showed support that most of the MMPI-2 scales have more clinical sensitivity than the RC scales at all levels of psychopathology and particularly at the less pathological levels. K correction does not account for the elevation differences. Most of the RC scales add little to no incremental validity to the MMPI-2 Clinical scales except for RC 1, RC 2, and RC 9 and these may be used as supplemental scales.

The Efficacy of Exposure and Response Prevention for Geriatric Obsessive Compulsive Disorder: A Clinical Case Illustration
Mairwen K. Jones,Bethany M. Wootton,Lisa D. Vaccaro
Case Reports in Psychiatry , 2012, DOI: 10.1155/2012/394603
Abstract: Obsessive compulsive disorder (OCD) is one of the most frequently occurring psychiatric conditions in older adults. While exposure and response prevention (ERP) is considered the most effective psychological treatment for children and adults with OCD, research investigating its effectiveness for older adults is scarce. This clinical case study investigates the effectiveness of ERP in an 80-year-old man with a 65-year history of OCD. The client received 14 individual, 50-minute ERP treatment sessions. Clinician-based Y-BOCS scores reduced by 65% from 20 (moderate) at pretreatment to 7 (subclinical) at 7-month posttreatment followup. OCI-R total scores reduced by 45% from 38 at baseline to 21 at 7-month follow-up. Despite his long history of the disorder, ERP was effective and well tolerated. The application of ERP for older adults with OCD, including age-specific modifications that may be required for this treatment approach, is discussed. 1. Introduction Obsessive compulsive disorder (OCD) is an anxiety disorder characterised by intrusive obsessions and/or repetitive, time-consuming compulsions [1]. It is a particularly disabling condition with significant impairment in functioning [2] and a high burden of disease and injury [3]. OCD is a common condition with twelve month prevalence estimates in adults noted to range from 0.6% to 1.9% [4]. The development of OCD after the age of 50 years is considered to be rare and is often associated with structural cerebral damage [5]. However, a considerable number of older adults are likely to be living with OCD [6], since they may have had the condition for many years and either not sought treatment or received inappropriate or ineffective treatments in the past [4]. For example, Grenier et al. [7] classified 1.5% of a sample of 2798 community dwelling adults aged over 65 years as probable OCD cases. Additionally, significant numbers of elderly people with OCD are seen in clinical practice [8]. In one sample of 183 patients seeking treatment for OCD 12% were older than 50 years [9]. As such, it has been argued that OCD is likely to be one of the most frequently occurring psychiatric conditions in this age group [10]. Additionally, older adults with untreated OCD are likely to experience significant disability across multiple areas of functioning [7], which could limit their ability to live independently in the community and substantially decrease their quality of life. Living with longstanding, persistent anxiety can also have a negative impact on the older adult’s physical health, by compromising the
Measuring Asymmetry in Time-Stamped Phylogenies
Bethany L. Dearlove?,Simon D. W. Frost
PLOS Computational Biology , 2015, DOI: 10.1371/journal.pcbi.1004312
Abstract: Previous work has shown that asymmetry in viral phylogenies may be indicative of heterogeneity in transmission, for example due to acute HIV infection or the presence of ‘core groups’ with higher contact rates. Hence, evidence of asymmetry may provide clues to underlying population structure, even when direct information on, for example, stage of infection or contact rates, are missing. However, current tests of phylogenetic asymmetry (a) suffer from false positives when the tips of the phylogeny are sampled at different times and (b) only test for global asymmetry, and hence suffer from false negatives when asymmetry is localised to part of a phylogeny. We present a simple permutation-based approach for testing for asymmetry in a phylogeny, where we compare the observed phylogeny with random phylogenies with the same sampling and coalescence times, to reduce the false positive rate. We also demonstrate how profiles of measures of asymmetry calculated over a range of evolutionary times in the phylogeny can be used to identify local asymmetry. In combination with different metrics of asymmetry, this combined approach offers detailed insights of how phylogenies reconstructed from real viral datasets may deviate from the simplistic assumptions of commonly used coalescent and birth-death process models.
The decay of radar echoes from meteors with particular reference to their use in the determination of temperature fluctuations near the mesopause
W. Jones
Annales Geophysicae (ANGEO) , 2003,
Abstract: The rate of decay of a radar echo from an ionised meteor train will be governed by the diffusion coefficient of the plasma and this in turn will depend on the temperature. Very recently the temperature fluctuations near the mesopause have been monitored by this means, by the recording of the decay times of underdense trains. The usual derivation of the precise expression relating the underdense echo decay time to the temperature contains two important assumptions, (i) that the train is created with a Gaussian ionisation profile, and (ii) that kinetic theory may be applied to calculate the diffusion coefficient. We investigate the effect of these assumptions, showing that the first assumption is unnecessary, an underdense backscatter echo decaying exponentially with a decay time equal to λ2/(32π2D), where λ is the wavelength and D the diffusion coefficient, independently of the initial distribution. However, the second assumption is shown to be incorrect, and whereas according to kinetic theory D∝T1/2/ρ, where T and ρ are the atmospheric temperature and density, the correct result is D∝Tρ. This leads to an appreciable correction to the results for the temperature fluctuations.
Dimebon disappointment
Roy W Jones
Alzheimer's Research & Therapy , 2010, DOI: 10.1186/alzrt49
Abstract: One swallow does not make a summer, and one positive clinical trial does not make an Alzheimer's drug. This was the Alzheimer Research Forum's response in March 2010 [1] to the news release by Pfizer Inc. and Medivation Inc. of the much-awaited data from the phase 3 CONNECTION study with dimebon (latrepirdine) [2]. Unfortunately, the trial met neither its co-primary (cognition and global function) nor its secondary efficacy endpoints. This disappointing news increased scepticism about the unusually positive results of the original phase 2 trial carried out in Russia and published in the Lancet in 2008 [3].Dimebon is orally available and was previously approved in Russia as a nonselective antihistamine but withdrawn from the market with the development of more selective compounds [4]. More recent papers described weak inhibition of butyrylcholinesterase, acetylcholinesterase, the N-methyl-D-aspartate receptor signalling pathway and the mitochondrial permeability transition pore opening [4-7]. Together with the demonstration of neuroprotective effects in Alzheimer's disease (AD) and Huntington's disease models, these observations supported the potential of dimebon as a treatment for AD - although the plausibility of dimebon's mechanism of action has been queried [8].In the phase 2 placebo-controlled study in mild-to-moderate AD funded by Medivation Inc., 155 patients (85% of those enrolled) completed the study [3]. Dimebon (20 mg three times daily) was safe and well tolerated, and significantly improved the clinical course of patients [3]; the mean change from baseline scores significantly favoured the drug for all five outcome measures: two measures of cognition (Mini-mental State Examination, and Alzheimer's Disease Assessment Scale cognitive subscale), one measure of activities of daily living (Alzheimer's Disease Cooperative Study activities of daily living), one measure of behaviour (Neuropsychiatric Inventory) and a global rating scale (Clinician's Interview-bas
Population and development beyond the first demographic transition: a focus on the experience of east and southeast Asian countries
Jones, Gavin W.;
Revista Brasileira de Estudos de Popula??o , 2011, DOI: 10.1590/S0102-30982011000200002
Abstract: this paper covers a wide scope, focusing on some trends in east and southeast asia that may be of interest to latin america. the first demographic transition has essentially been completed in both regions. the issue is what should now be the focus of our consideration of population and development? east asian countries are now stressing issues of ultra-low fertility, and policies to raise fertility. they are not comfortable with the prospect of making up future deficits through international migration. the paper also deals briefly with studies of dynamics of change in mega-urban regions, and argues that comparative studies on latin america and asia could be valuable. issues of poverty, development, and equity are then addressed, with particular emphasis on the role of education as a key to equality and development. one dilemma is that in east asia, the generally commendable obsession with education is one factor making for very low levels of fertility. finally, the paper touches on population and environmental issues.

Imagining Jefferson and Hemings in Paris

Abstract: In Yearning: Race, Gender, and Cultural Politics, cultural critic bell hooks argues that “no one seems to know how to tell the story” of white men romantically involved with slave women because long ago another story supplanted it: “that story, invented by white men, is about the overwhelming desperate longing black men have to sexually violate the bodies of white women.” Narratives of white exploitation and black solidarity have made it difficult to imagine consensual sex and impossible to i...
