A Efficacious Theoretical Perspective of Rural Female School Superintendents\u27 Self-Sustainability
The landscape of the rural superintendancy is in the midst of a leadership turnover as a significant number of its current administrators reach retirement age. Discussions in the literature have delineated the characteristics of successful rural superintendents and the barriers that threaten their achievement. It lacks, however, adequate discussion of how women have aspired to and sustained success in rural superintendencies. The qualitative case study presented in this report includes the narratives of five novice, rural, and female superintendents. An efficacious theoretical framework was identified as the lens through which the accounts could best be analyzed and discussed, including proposed implications for additional research to further explore this framework and the academyâs preparation of rural female superintendents
The Effect of Educational Games on the Level of Motivation in Science of Grade IV Students in Angel Villarica Central School
The concern of this study is to determine The Effect of Educational Games on the Level of Motivation of Grade 4 Students in Angel Villarica Central Elementary School. A quantitative research design employing an experimental method was used in the study. The essential data were gathered from a total number of seventy-three (73) respondents, 36 students from the control group and 37 students from the experimental group, with the aid of a questionnaire validated by a panel of experts. The statistical tools used in this study were Average Weighted Mean and t-test for Independent Sample Means. The study proved that there was no significant difference between the mean gain scores of the experimental and control groups. It means that the use of educational games has no significant effect on the level of motivation in science. However, educational games can be considered as an alternative method in delivering the Science lesson. It was being recommended in the study to conduct a similar study in the future to confirm that educational games have no effect on the level of motivation and involve a wider scope in the conduct of the stud
Mental Health Help-Seeking Intentions Among International and African American College Students: An Application of the Theory of Planned Behavior
This study examined the relationship between social-cognitive factors (e.g., attitudes, subjective norms, and perceived behavioral control), psychological distress, and help-seeking intentions for a sample of 111 international and African American college students. The results of this study showed that the Theory of Planned Behavior (TPB) variables (e.g., attitudes, subjective norms, and perceived behavioral control) accounted for 17.7 % of the variance in help-seeking intentions. The first hypothesis, which predicted that positive attitudes toward mental health services and perceived behavioral control would be significant predictors of the studentsâ intentions to seek mental health services, was partially supported. Perceived behavioral control was the strongest predictor of helpseeking intentions. Contrary to our expectations, attitudes toward mental health services were not a significant predictor of mental health seeking intentions. The second hypothesis was not supported. There was no significant difference in mean intention scores for African American college students compared to international college students
Factors that Contribute to the Adjustment of International Students
Leaving home to attend college is an important milestone for college students. However, the transition from home to college can be challenging, especially for students studying abroad. In this article, the authors explore factors that contribute to the academic, cultural, social, and psychological adjustments of international students. Adjustment issues include psychological distress such as homesick, depression, and anxiety. This article seeks to increase the readerâs understanding of some of the issues faced by international students during the process of adjusting to a new collegiate environment. More specifically, the article discusses factors that contribute to adjustment and different phases of cultural adjustment. This article may help the students, educational institutions, and policy makers to provide the resources necessary for a seamless transition for international students to overcome the issues
One-year outcomes after transcatheter insertion of an interatrial shunt device for the management of heart failure with preserved ejection fraction
BackgroundâHeart failure with preserved ejection fraction has a complex pathophysiology and remains a therapeutic challenge. Elevated left atrial pressure, particularly during exercise, is a key contributor to morbidity and mortality. Preliminary analyses have demonstrated that a novel interatrial septal shunt device that allows shunting to reduce the left atrial pressure provides clinical and hemodynamic benefit at 6 months. Given the chronicity of heart failure with preserved ejection fraction, evidence of longer-term benefit is required.
Methods and ResultsâPatients (n=64) with left ventricular ejection fraction â„40%, New York Heart Association class IIâIV, elevated pulmonary capillary wedge pressure (â„15 mmâHg at rest or â„25 mmâHg during supine bicycle exercise) participated in the open-label study of the interatrial septal shunt device. One year after interatrial septal shunt device implantation, there were sustained improvements in New York Heart Association class (P<0.001), quality of life (Minnesota Living with Heart Failure score, P<0.001), and 6-minute walk distance (P<0.01). Echocardiography showed a small, stable reduction in left ventricular end-diastolic volume index (P<0.001), with a concomitant small stable increase in the right ventricular end-diastolic volume index (P<0.001). Invasive hemodynamic studies performed in a subset of patients demonstrated a sustained reduction in the workload corrected exercise pulmonary capillary wedge pressure (P<0.01). Survival at 1 year was 95%, and there was no evidence of device-related complications.
ConclusionsâThese results provide evidence of safety and sustained clinical benefit in heart failure with preserved ejection fraction patients 1 year after interatrial septal shunt device implantation. Randomized, blinded studies are underway to confirm these observations
Transatlantic collection of health informatics competencies
The electronic collection, processing and management of information is becoming increasingly important in healthcare. Because of the nature of the healthcare provision and delivery process, where the health, safety and quality of human lives are impacted on a daily basis, it is critical that those who work in the field are competent and able to perform all clinical, administrative, research and technology-impacted facets of their roles.The United States and the European Union have been working to encourage broader and more effective use of Information and Communications Technology (ICT) within healthcare. The development, use and governance of ICT within healthcare, often called health informatics, requires a number of competences which need to be identified and integrated into relevant skills assessment, education and training. Ultimately, this will help produce a more proficient and a more confident mobile health informatics-empowered workforce.A structured set of health information technology and eHealth implementation competences was collected in a co-operation project by voluntary experts in USA and European Union. The project took a deliberately broad starting point, seeking and reviewing an extensive range of related competencies. The skills cover the following domains of professions working with health information technology: direct patient care; administrative; engineering/information, communication, and technology (ICT); informatics; and research and biomedicine. The aggregation of over one thousand competencies was classified to a baseline set of skills and four levels of expertise in 33 focus areas according to Bloomâs taxonomy. The data set also contains definitions of 268 âtypicalâ professional roles. The use of the collection of competencies is supported by an open access web tool through which all the competencies can be searched through a query mechanism.The limitation of this work is that only the Acute Care segment of roles and competencies impacted by ICT was evaluated within the scope of this project, however, this subset of other care settings such as ambulatory, rehabilitative care, surgery, and others serves as a representative set of roles and competencies within the health care field as well as a being an important proof of concept for future usefulness of the work if extended beyond its current span. This project has made a contribution to the potential improvement of workforce mobility internationally
On the alleged simplicity of impure proof
Roughly, a proof of a theorem, is âpureâ if it draws only on what is âcloseâ or âintrinsicâ to that theorem. Mathematicians employ a variety of terms to identify pure proofs, saying that a pure proof is one that avoids what is âextrinsic,â âextraneous,â âdistant,â âremote,â âalien,â or âforeignâ to the problem or theorem under investigation. In the background of these attributions is the view that there is a distance measure (or a variety of such measures) between mathematical statements and proofs. Mathematicians have paid little attention to specifying such distance measures precisely because in practice certain methods of proof have seemed self- evidently impure by design: think for instance of analytic geometry and analytic number theory. By contrast, mathematicians have paid considerable attention to whether such impurities are a good thing or to be avoided, and some have claimed that they are valuable because generally impure proofs are simpler than pure proofs. This article is an investigation of this claim, formulated more precisely by proof- theoretic means. After assembling evidence from proof theory that may be thought to support this claim, we will argue that on the contrary this evidence does not support the claim
Staphylococcus aureus infections following knee and hip prosthesis insertion procedures
BackgroundStaphylococcus aureus is the most common and most important pathogen following knee and hip arthroplasty procedures. Understanding the epidemiology of invasive S. aureus infections is important to quantify this serious complication.MethodsThis nested retrospective cohort analysis included adult patients who had undergone insertion of knee or hip prostheses with clean or clean-contaminated wound class at 11 hospitals between 2003–2006. Invasive S. aureus infections, non-superficial incisional surgical site infections (SSIs) and blood stream infections (BSIs), were prospectively identified following each procedure. Prevalence rates, per 100 procedures, were estimated.Results13,719 prosthetic knee (62%) and hip (38%) insertion procedures were performed. Of 92 invasive S. aureus infections identified, SSIs were more common (80%) than SSI and BSI (10%) or BSI alone (10%). The rate of invasive S. aureus infection/100 procedures was 0.57 [95% CI: 0.43-0.73] for knee insertion and 0.83 [95% CI: 0.61-1.08] for hip insertion. More than half (53%) were methicillin-resistant. Median time-to-onset of infection was 34 and 26 days for knee and hip insertion, respectively. Infection was associated with higher National Healthcare Safety Network risk index (p ≤ 0.0001).ConclusionsPost-operative invasive S. aureus infections were rare, but difficult-to-treat methicillin-resistant infections were relatively common. Optimizing preventative efforts may greatly reduce the healthcare burden associated with S. aureus infections
Early Pleistocene large mammals from Makaâamitalu, Hadar, lower Awash Valley, Ethiopia
The Early Pleistocene was a critical time period in the evolution of eastern African mammal faunas, but fossil assemblages sampling this interval are poorly known from Ethiopia's Afar Depression. Field work by the Hadar Research Project in the Busidima Formation exposures (similar to 2.7-0.8 Ma) of Hadar in the lower Awash Valley, resulted in the recovery of an early Homo maxilla (A.L. 666-1) with associated stone tools and fauna from the Maka'amitalu basin in the 1990s. These assemblages are dated to similar to 2.35 Ma by the Bouroukie Tuff 3 (BKT-3). Continued work by the Hadar Research Project over the last two decades has greatly expanded the faunal collection. Here, we provide a comprehensive account of the Maka'amitalu large mammals (Artiodactyla, Carnivora, Perissodactyla, Primates, and Proboscidea) and discuss their paleoecological and biochronological significance. The size of the Maka'amitalu assemblage is small compared to those from the Hadar Formation (3.45-2.95 Ma) and Ledi-Geraru (2.8-2.6 Ma) but includes at least 20 taxa. Bovids, suids, and Theropithecus are common in terms of both species richness and abundance, whereas carnivorans, equids, and megaherbivores are rare. While the taxonomic composition of the Maka'amitalu fauna indicates significant species turnover from the Hadar Formation and Ledi-Geraru deposits, turnover seems to have occurred at a constant rate through time as taxonomic dissimilarity between adjacent fossil assemblages is strongly predicted by their age difference. A similar pattern characterizes functional ecological turnover, with only subtle changes in dietary proportions, body size proportions, and bovid abundances across the composite lower Awash sequence. Biochronological comparisons with other sites in eastern Africa suggest that the taxa recovered from the Maka'amitalu are broadly consistent with the reported age of the BKT-3 tuff. Considering the age of BKT-3 and biochronology, a range of 2.4-1.9 Ma is most likely for the faunal assemblage.info:eu-repo/semantics/publishedVersio
