The Development of Instruments for Assessment of Instructional Practices in Standards-Based Teaching
We provide a description and rationale for the development of two instruments: 1) a classroom observation protocol; and, 2) a teacher interview protocolâdesigned to document the impact of reform-based professional development with undergraduate mathematics and science faculty, and its impact on the resultant preparation of teachers. Constructed upon review of the research on teaching and standards documents in mathematics and science, these instruments form the basis for data collection in a three-year longitudinal study of teaching practice among early career teachers as well as undergraduate college faculty. In addition, we suggest further applications of the observation protocol beyond the original purpose of our research study
Student perceptions of their autonomy at University
© 2017, The Author(s). Learner autonomy is a primary learning outcome of Higher Education in many countries. However, empirical evaluation of how student autonomy progresses during undergraduate degrees is limited. We surveyed a total of 636 studentsâ self-perceived autonomy during a period of two academic years using the Autonomous Learning Scale. Our analysis suggests that students do not perceive themselves as being any more autonomous as they progress through University. Given the relativity of self-perception metrics, we suggest that our results evince a âred queenâ effect. In essence, as course expectations increase with each year, each studentâs self-perceived autonomy relative to their ideal remains constant; we term this the âmoving goalpostâ hypothesis. This article corroborates pedagogical literature suggesting that providing students with opportunities to act autonomously and develop confidence is key to developing graduates who have the independence that they need in order to be successful in the workplace
TikTok as Art: Visual Culture Art Education in an Afterschool Art Program
This research and the objective were to investigate the firsthand experience of
visual culture art education in an after-school art program. The after-school
program was focused mainly on an underserved population. We focused our
concentration on the social media app TikTok. The author investigated visual
culture theorists and discovered ideas from Terry Barrett and his use of
denotations and connotations and their relationship to art. The participants were
members of the Boys and Girls Club of Nacogdoches who analyzed TikTok
videos using annotations and denotations, then in return created their own
individual videos inspired by an original TikTok video. The participants discussed
and analyzed TikTok videos which led to deeper discussions into the customer
services industry, African American representation, and internet safety. Through
observations and discussions, along with individual and group interviews, the
research project led to the need for narrow guidelines on visual culture, social
justice, and safety on the internet
A Comparison of Vegetation Composition in Urban and Rural Floodplans Following Removal of Chinese Privet (Ligustrum Sinense)
An important aspect of restoration ecology is the removal of non-native invasive plants. While restorations in urban areas involve similar challenges to restorations in rural areas, urban efforts also contend with unique issues such as increased fragmentation and decreased seed sources for native species. This study examined efforts to eradicate Ligustrum sinense and allow native vegetation to occupy the landscape. The herbaceous layer was inventoried at study plots in riparian bottomlands of four Atlanta, Georgia, natural areas two years after start of treatment to remove L. sinense. Plant taxa were described and compared to a similar study conducted in a rural area of northeastern Georgia. Significant abundance of L. sinense was recurring at urban sites while recurrence at rural sites was low. Other non-native invasive species, frequently used in urban landscaping, were also occurring at urban sites and not at rural sites
Training health visitors in cognitive behavioural and person-centred approaches for depression in postnatal women as part of a cluster randomised trial and economic evaluation in primary care: the PoNDER trial
Aim: This paper aims to describe the training preparation for health visitors who took part in the intervention arm of a cluster randomised controlled trial and economic evaluation of training for health visitors â the POstNatal Depression Economic evaluation and Randomised (the PoNDER) trial. A secondary aim is to make available, by electronic links, the training manuals developed for and used for the cognitive behavioural approach (CBA) and the person-centred approach (PCA) training for the health visitors. The paper is of relevance to health visitors, general practitioners, nurse practitioners, midwives, clinical psychologists, mental health nurses, community psychiatric nurses, counsellors, and service commissioners.
Background: The trial clinical outcomes have been published, indicating the pragmatic effectiveness of the package of training for health visitors to identify depressive symptoms and provide a psychologically informed intervention. The training was associated with a reduction in depressive symptoms at six months postnatally among intervention group women and some evidence of a benefit for the intervention group for some of the secondary outcomes at 18 months follow-up.
Methods: The two experimental interventions examined in the PoNDER trial built upon promising work on the potential for psychological interventions to help women recover from postnatal depression as an alternative to pharmaceutical interventions and to address the limitations of previous research in the area.
Findings: The package of health visitor training comprised the development of clinical skills in assessing postnatal women and identifying depressive symptoms, and the delivery of a CBA or a PCA for eligible women. This was the largest trial a health visitor intervention and of postnatal depression ever conducted. We are aware of no other rigorously performed trial that has published details of an extensively tested training programme for the benefit of health-care professionals and clients
Optical/Infrared Observations of the Anomalous X-ray Pulsar 1E 1048.1-5937 During Its 2007 X-Ray Flare
We report on optical and infrared observations of the anomalous X-ray pulsar
(AXP) 1E 1048.1-5937, made during its ongoing X-ray flare which started in 2007
March. We detected the source in the optical I and near-infrared Ks bands in
two ground-based observations and obtained deep flux upper limits from four
observations, including one with the Spitzer Space Telescope at 4.5 and 8.0
microns. The detections indicate that the source was approximately 1.3--1.6
magnitudes brighter than in 2003--2006, when it was at the tail of a previous
similar X-ray flare. Similar related flux variations have been seen in two
other AXPs during their X-ray outbursts, suggesting common behavior for large
X-ray flux variation events in AXPs. The Spitzer flux 1E 1048.1-5937 limits are
sufficiently deep that we can exclude mid-infrared emission similar to that
from the AXP 4U 0142+61, which has been interpreted as arising from a dust disk
around the AXP. The optical/near-infrared emission from probably has a
magnetospheric origin. The similarity in the flux spectra of 4U 0142+61 and 1E
1048.1-5937 challenges the dust disk model proposed for the latter.Comment: 5 pages, 1 figure, accepted by Ap
Overview of the incidence, early identification and management of sepsis
Sepsis is a potentially life-threatening condition that is triggered by an infection. Sepsis is an urgent public health issue globally, and is one of the leading causes of death in emergency departments and hospitals. However, consensus definitions of sepsis are imprecise and the incidence and costs of the condition are thought to be underestimated. This article discusses the incidence of sepsis globally and nationally, and the effects of the condition. It emphasises the early identification and effective management of sepsis, which remain crucial to improving patient outcomes such as morbidity and mortality. It also outlines the nurseâs role in providing sepsis care
Comparative genomics approaches accurately predict deleterious variants in plants
Recent advances in genome resequencing have led to increased interest in prediction of the functional consequences of genetic variants. Variants at phylogenetically conserved sites are of particular interest, because they are more likely than variants at phylogenetically variable sites to have deleterious effects on fitness and contribute to phenotypic variation. Numerous comparative genomic approaches have been developed to predict deleterious variants, but the approaches are nearly always assessed based on their ability to identify known disease-causing mutations in humans. Determining the accuracy of deleterious variant predictions in nonhuman species is important to understanding evolution, domestication, and potentially to improving crop quality and yield. To examine our ability to predict deleterious variants in plants we generated a curated database of 2,910 Arabidopsis thaliana mutants with known phenotypes. We evaluated seven approaches and found that while all performed well, their relative ranking differed from prior benchmarks in humans. We conclude that deleterious mutations can be reliably predicted in A. thaliana and likely other plant species, but that the relative performance of various approaches does not necessarily translate from one species to another
Womenâs views on anxiety in pregnancy and the use of anxiety instruments: a qualitative study
Objective: To explore womenâs experience of anxiety in pregnancy and views on the use of anxiety instruments in antenatal care.
Background: Anxiety in pregnancy is associated with adverse birth outcomes, developmental and behavioural problems in infants and postnatal depression. Despite recommendations for routine psychological assessment in pregnancy the optimal methods to identify anxiety in pregnancy have not been confirmed.
Methods: A qualitative study using two focus group discussions was undertaken. Focus group one included women in a community setting and focus group two included women in a hospital clinic setting who had received additional support for anxiety in pregnancy. Participants were women who had given birth within the past nine months and considered themselves to have been anxious during their pregnancy.
Results: Three main themes were identified using template analysis: sources of support, administration of anxiety instruments and the use of instruments to prompt discussion. Women stated anxiety instruments could help them to identify their anxious feelings and prompt a discussion around those feelings. However they expressed concerns surrounding the administration of anxiety instruments and questioned how useful they would be in helping women access help and support.
Conclusions: The introduction of anxiety instruments in antenatal care may present an opportunity to discuss womenâs emotional health and anxieties. Providing women with sufficient time to discuss their anxious feelings, identified by such instruments, could facilitate access to additional support
Predictive validity of the CriSTAL tool for short-term mortality in older people presenting at Emergency Departments: a prospective study
© 2018, The Author(s). Abstract: To determine the validity of the Australian clinical prediction tool Criteria for Screening and Triaging to Appropriate aLternative care (CRISTAL) based on objective clinical criteria to accurately identify risk of death within 3 months of admission among older patients. Methods: Prospective study of â„ 65 year-olds presenting at emergency departments in five Australian (Aus) and four Danish (DK) hospitals. Logistic regression analysis was used to model factors for death prediction; Sensitivity, specificity, area under the ROC curve and calibration with bootstrapping techniques were used to describe predictive accuracy. Results: 2493 patients, with median age 78â80 years (DKâAus). The deceased had significantly higher mean CriSTAL with Australian mean of 8.1 (95% CI 7.7â8.6 vs. 5.8 95% CI 5.6â5.9) and Danish mean 7.1 (95% CI 6.6â7.5 vs. 5.5 95% CI 5.4â5.6). The model with Fried Frailty score was optimal for the Australian cohort but prediction with the Clinical Frailty Scale (CFS) was also good (AUROC 0.825 and 0.81, respectively). Values for the Danish cohort were AUROC 0.764 with Fried and 0.794 using CFS. The most significant independent predictors of short-term death in both cohorts were advanced malignancy, frailty, male gender and advanced age. CriSTALâs accuracy was only modest for in-hospital death prediction in either setting. Conclusions: The modified CriSTAL tool (with CFS instead of Friedâs frailty instrument) has good discriminant power to improve prognostic certainty of short-term mortality for ED physicians in both health systems. This shows promise in enhancing clinicianâs confidence in initiating earlier end-of-life discussions
