The Effects of Technology-Based Conducting Practice on Skill Achievement in Novice Conductors
The purpose of this study was to compare technology-based practice (Radio Baton and Digital Conducting System) to self-practice (recorded music) on the skill achievement of beginning conductors. Participants (N = 33) were undergraduate music majors—education and performance—from two beginning conducting classes randomly assigned to either the technology-based group or the self-practice group. Subjects worked for three, 15-minute sessions on the following skills: staccato conducting, legato conducting, and steadiness of tempo. The experimental design was a pretest-posttest using two conducting etudes to measure six dependent variables: staccato conducting, staccato presence, staccato steadiness of tempo, legato conducting, legato presence, and legato steadiness of tempo. Three expert judges scored videotaped pre and posttests with interjudge reliability ranging from .77 to .84. Six Analyses of Covariance tests (ANCOVA) were used to analyze the aforementioned dependent variables. A significant difference resulted between treatment and control groups for only the legato conducting variable (p = .05). The researchers concluded that a longer treatment period was perhaps necessary to produce a significant difference between the groups on the other variables
Cartel Car Bombings in Mexico
View the Executive SummaryContemporary Mexican cartel use of car bombs began in mid-July 2010 and has since escalated. Given the proximity to the United States, some literally within miles of the border, the car bombings, with about 20 incidents identified over the last 2 1/2 years, should be of interest to local, state, and federal U.S. law enforcement, the U.S. Army, and other governmental institutions which are providing increasing support to Mexican federal agencies. An historical overview and analysis of cartel car bomb use in Mexico provides context, insights, and lessons learned stemming from the Medellin and Cali cartel car bombing campaigns. In order to generate insights into future cartel car bombings in Mexico, the identification of such potentials offers a glimpse into cartel “enemy intent,” a possible form of actionable strategic intelligence. For Mexico, steady and both slowly and quickly increasing car bomb use trajectories may exist. The prognosis for decreasing car bomb deployment appears unlikely. If cartel car bombs were to be deployed on U.S. soil or against U.S. personnel and facilities in Mexico, such as our consulates, we could expect that a pattern of indications and warnings (I&W) would be evident prior to such an attack(s). In that case, I&W would be drawn from precursor events such as grenade and improvised explosive device (IED) attacks (or attempted attacks) on our personnel and facilities and on evolving cartel car bomb deployment patterns in Mexico. The authors conclude with initial recommendations for U.S. Army and defense community support to the military and the federal, state, and local police agencies of the Mexican state, and the various U.S. federal, state, and local police agencies operating near the U.S.-Mexican border. The extent of support in intelligence, organization, training, and equipment is highlighted, as well as the extent that these forms of support should be implemented to counter cartel vehicle-borne IEDs and overall cartel threats.https://press.armywarcollege.edu/monographs/1320/thumbnail.jp
Is University Nursing Education in Canada Taking the Lead in a World Focused on Sustainable Development? / La formation universitaire au Canada est-elle à l’avant-plan dans un monde centré sur le développment durable?
Global Health is widely being adopted by universities and higher education institutions in Canada and around the world. The current global climate has given rise to an emphasis on the necessity of global health education for nurses. Nursing educators as well as nursing students are seeking guidance as they integrate global health as part of their learning, teaching, research and practice. In September 2015, the member states of the United Nations adopted the Sustainable Development Goals (SDGs): seventeen goals to end poverty, protect the environment, and ensure health and well-being for all. These seventeen goals will guide the world’s development agenda for the next 15 years. Canadian universities, especially nursing faculties/schools are uniquely placed to help implement the SDGs, particularly goals three and four which focus on good health and well-being and quality education. Little has been done in understanding universities and in particular nursing’s overall commitment to achieving these 17 goals. Nursing is the largest health care provider group and it is critical to understand our educational responsibilities in attaining the SDGs. The purpose of this paper is to share findings from a study which examined Canada’s largest nursing faculties’/schools of nursing’s mission statements and strategic plans, and to discuss how these mandates align with the achievement of the SDGs.
Résumé
La notion de « santé mondiale » est largement utilisée par les universités et les établissements d’enseignement supérieur au Canada et partout dans le monde. Le climat mondial actuel a fait naître le besoin de former les infirmières au domaine de la santé mondiale. Les professeures et les étudiantes en sciences infirmières sont à la recherche d’orientations alors qu’elles intègrent la santé mondiale à leur apprentissage/enseignement, recherche et pratique. En septembre 2015, les États membres de l’ONU ont adopté les Objectifs de développement durable (ODD) : dix-sept objectifs qui visent à mettre fin à la pauvreté, à protéger l’environnement et à garantir la santé et le bien-être pour tous. Au cours des 15 prochaines années, ces dix-sept objectifs vont guider le développement à l’échelle mondiale. Les universités canadiennes, et surtout les facultés de sciences infirmières, sont particulièrement bien placées pour contribuer à la mise en œuvre de ces ODD, plus spécifiquement les objectifs trois et quatre qui portent sur la santé et le bien-être et une éducation de qualité. Peu d’efforts ont été faits pour comprendre l’engagement des universités et surtout, celui des sciences infirmières, pour atteindre ces 17 objectifs. Les infirmières représentent le plus important groupe de prestataires de soins de santé au pays, et il est essentiel de comprendre nos responsabilités en matière de formation pour la réalisation des ODD de l’ONU. Le but de cet article est de faire part des résultats d’une étude qui portait sur les énoncés de mission les plans stratégiques des plus grandes facultés de sciences infirmières/école de sciences infirmières au Canada, et de discuter de la correspondance de ces mandats avec l’atteinte de ces ODD
Older persons participation in hard martial arts: Opportunities to improve psychological well-being? A scoping review.
International Journal of Exercise Science 17(5): 183-198, 2024. This study aims to explore the potential psychological and cognitive advantages for older individuals engaged in hard martial arts (HMA), through a comprehensive scoping review of literature up to 2023. Specifically, it examines the extent of changes in cognition, mental state, and quality of life among elderly participants of HMA. Inclusion criteria were studies conducted on healthy persons who were over 50 years of age. Only papers published in the English language were included. The search was undertaken in electronic databases and sources of grey literature. Thirteen papers with a total of 514 participants met the inclusion criteria. Improved cognition and decreased levels of anxiety and depression were emerging themes. Together, these factors contributed to the quality of life of participants. HMA was found to benefit cognitive abilities and psychological well-being, increasing quality of life more than traditional exercise alone. Findings suggested duration of training influenced change more than frequency. The limited number of studies exploring the effects of HMA on mental wellness and cognitive ability in older adults underscores the need for further research. The findings of this review suggest cognitive and quality of life improvements and reduced depression and anxiety in individuals engaging in HMA. This review serves as a foundation for soundly designed future research

Telomere disruption results in non-random formation of de novo dicentric chromosomes involving acrocentric human chromosomes
Copyright: © 2010 Stimpson et al.Genome rearrangement often produces chromosomes with two centromeres (dicentrics) that are inherently unstable because of bridge formation and breakage during cell division. However, mammalian dicentrics, and particularly those in humans, can be quite stable, usually because one centromere is functionally silenced. Molecular mechanisms of centromere inactivation are poorly understood since there are few systems to experimentally create dicentric human chromosomes. Here, we describe a human cell culture model that enriches for de novo dicentrics. We demonstrate that transient disruption of human telomere structure non-randomly produces dicentric fusions involving acrocentric chromosomes. The induced dicentrics vary in structure near fusion breakpoints and like naturally-occurring dicentrics, exhibit various inter-centromeric distances. Many functional dicentrics persist for months after formation. Even those with distantly spaced centromeres remain functionally dicentric for 20 cell generations. Other dicentrics within the population reflect centromere inactivation. In some cases, centromere inactivation occurs by an apparently epigenetic mechanism. In other dicentrics, the size of the alpha-satellite DNA array associated with CENP-A is reduced compared to the same array before dicentric formation. Extrachromosomal fragments that contained CENP-A often appear in the same cells as dicentrics. Some of these fragments are derived from the same alpha-satellite DNA array as inactivated centromeres. Our results indicate that dicentric human chromosomes undergo alternative fates after formation. Many retain two active centromeres and are stable through multiple cell divisions. Others undergo centromere inactivation. This event occurs within a broad temporal window and can involve deletion of chromatin that marks the locus as a site for CENP-A maintenance/replenishment.This work was supported by the Tumorzentrum Heidelberg/Mannheim grant (D.10026941)and by March of Dimes Research Foundation grant #1-FY06-377 and NIH R01 GM069514
A national audit of the management pathways for new HIV diagnoses
The British HIV Association recommends that new diagnoses be reviewed by an HIV specialist within two weeks. NHS England outcome measures include the proportion of new diagnoses commencing antiretroviral therapy (ART) within 91 days. We aimed to review the extent to which these recommendations were followed, to explore the topics discussed with new diagnoses, and to identify reasons behind delayed ART initiation. UK specialist HIV services were invited to retrospectively review the notes of their last 40 new diagnoses over a 15-month period. One-hundred and thirty-two services provided data for 2281 eligible individuals. Most new diagnoses were reviewed by a specialist within two weeks (67.7%) and were commenced on ART within 91 days (83%), however, there were some concerning delays in those tested at home and in general practice. Partner notification and treatment benefits were discussed with most individuals, unlike the availability of community support and U = U (“undetectable equals untransmittable”). Lengthy delays in ART initiation were mostly due to individuals initially declining ART or missing appointments. Our findings suggest a need for more streamlined pathways into HIV care, review of new diagnoses who have not commenced ART within 8 weeks, and protocol development to ensure discussion of relevant topics
Integration of airborne and ground observations of nitryl chloride in the Seoul metropolitan area and the implications on regional oxidation capacity during KORUS-AQ 2016
Nitryl chloride (ClNO2) is a radical reservoir species that releases chlorine radicals upon photolysis. An integrated analysis of the impact of ClNO2 on regional photochemistry in the Seoul metropolitan area (SMA) during the Korea-United States Air Quality Study (KORUS-AQ) 2016 field campaign is presented. Comprehensive multiplatform observations were conducted aboard the NASA DC-8 and at two ground sites (Olympic Park, OP; Taehwa Research Forest, TRF), representing an urbanized area and a forested suburban region, respectively. Positive correlations between daytime Cl2 and ClNO2 were observed at both sites, the slope of which was dependent on O3 levels. The possible mechanisms are explored through box model simulations constrained with observations. The overall diurnal variations in ClNO2 at both sites appeared similar but the nighttime variations were systematically different. For about half of the observation days at the OP site the level of ClNO2 increased at sunset but rapidly decreased at around midnight. On the other hand, high levels were observed throughout the night at the TRF site. Significant levels of ClNO2 were observed at both sites for 4-5 h after sunrise. Airborne observations, box model calculations, and back-trajectory analysis consistently show that these high levels of ClNO2 in the morning are likely from vertical or horizontal transport of air masses from the west. Box model results show that chlorine-radical-initiated chemistry can impact the regional photochemistry by elevating net chemical production rates of ozone by 25% in the morning
Low alanine aminotransferase and higher cardiovascular events in type 2 diabetes: analysis of the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study
Aims Non-alcoholic fatty liver disease (NAFLD) is common in type 2 diabetes and associated with higher risk of cardiovascular disease. This study aimed to determine whether alanine aminotransferase (ALT) or gamma-glutamyltransferase (GGT), as markers of liver health and NAFLD, might predict cardiovascular events in this population. Methods Data from the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study were analysed to examine the relationship between liver enzymes and incident cardiovascular events (nonfatal myocardial infarction, stroke, coronary and other cardiovascular death, coronary or carotid revascularization) over 5 years. Results ALT had a linear inverse relationship with the first cardiovascular event on study. After adjustment, for every standard deviation higher baseline ALT (13.2U/L), the risk of an event was 7%(95%CI 4–13, P=0.02) lower. Participants with ALT below and above the reference range 8–41 U/L for women and 9–59 U/L for men, had a hazard ratio of an event of 1.86(95%CI, 1.12–3.09) and 0.65(95%CI, 0.49–0.87), respectively (P=0.001). No relationship was found for GGT. Conclusions The data may indicate that in type 2 diabetes — associated with higher ALT due to prevalent NAFLD — lower ALT is a marker of hepatic or systemic frailty rather than health
DNA content of a functioning chicken kinetochore
© The Author(s) 2014. In order to understand the three-dimensional structure of the functional kinetochore in vertebrates, we require a complete list and stoichiometry for the protein components of the kinetochore, which can be provided by genetic and proteomic experiments. We also need to know how the chromatin-containing CENP-A, which makes up the structural foundation for the kinetochore, is folded, and how much of that DNA is involved in assembling the kinetochore. In this MS, we demonstrate that functioning metaphase kinetochores in chicken DT40 cells contain roughly 50 kb of DNA, an amount that corresponds extremely closely to the length of chromosomal DNA associated with CENP-A in ChIP-seq experiments. Thus, during kinetochore assembly, CENP-A chromatin is compacted into the inner kinetochore plate without including significant amounts of flanking pericentromeric heterochromatin. © 2014 The Author(s).Wellcome Trust [grant number 073915]; Wellcome Trust Centre for Cell Biology (core grant numbers 077707 and 092076); Darwin Trust of Edinburg
