Interactive Whiteboards and Elementary Students\u27 Writing
This research focused on the use of an interactive white board in two third grade classrooms to assist students in learning to write main ideas and supporting details as introduced through The Six Traits writing model. The study focused on a control group and an experimental group completing similar writing lessons. The experimental groups\u27 lessons centered around the use of an interactive white board and various activities and interactive games to enforce the learning. The results from the study can aid educators in the incorporation of an interactive white board to assist instruction
Reliability and Validity of Ratings of Perceived Exertion in Persons With Multiple Sclerosis
Objective: To test the reliability and validity of using the Borg rating of perceived exertion (RPE) scale (ratings 6e20) in persons with multiple sclerosis (PwMS).
Design: Nonrandomized repeated measures.
Setting: Research laboratory.
Participants: Volunteer sample (N=27) comprised of 16 PwMS (10 women) and 11 age-matched persons without multiple sclerosis (MS) (6 women). Clinical measures included symptomatic fatigue, depression, and MS functional capacity.
Interventions: A submaximal cycling test was performed to estimate maximal capacity. Participants then pedaled for 2 minutes at 50% and 60% of predicted maximal oxygen consumption per unit time (V̇O2), and physiological measures and RPE were obtained (week 1: response protocol). One week later, participants replicated the prescribed V̇O2 using the RPE range from week 1 (week 2: reproduction protocol). V̇O2, heart rate, and respiratory quotient were measured continuously; RPE and workload were measured every minute; and blood lactate and mean arterial pressure were measured after exercise.
Main Outcome Measures: RPE, workload, V̇O2, and heart rate from week 1 to week 2.
Results: PwMS had greater fatigue (P2, and heart rate were similar between groups. Both groups had an intraclass correlation coefficient \u3e.86 for RPE, workload, and V̇O2. The intraclass correlation coefficient was comparatively lower for heart rate for both groups (MS group: .72, non-MS group: .83). RPE was highly correlated with V̇O2(rZ.691, P
Conclusions: Results suggest that RPE can be reliably reproduced, is valid, and may be used in exercise prescription in mildly to moderately impaired PwMS during cycling exercise
Theory-based communication skills training for medicine counter assistants to improve consultations for non-prescription medicines
Context: Medicine counter assistants (MCAs) supply the majority of non-prescription medicines (NPMs) to consumers. Suboptimal communication during consultations between consumers and MCAs has been identified as a major cause of inappropriate supply. Evidence from medical consultations suggests that training in specified communication skills can change professional behaviour. Methods: A feasibility study was conducted to evaluate the effect of theory-based communication skills training for MCAs. Thirty MCAs were recruited from 21 community pharmacies in Grampian, Scotland. The intervention comprised 2 4-hour training sessions, held 1 month apart. The sessions were informed by results from previous studies and the Calgary−Cambridge evidence-based model of communication skills training. Strategies for guiding individuals through change were adopted from cognitive behavioural therapy techniques. The theory of planned behaviour was used to assess potential pathways to behaviour change. Recorded data were collected during covert visits to the pharmacies by simulated patients at baseline and 1 month after each training session. Communication performance was measured as the number and type of questions asked. Results: Compared with baseline measures, the total number of questions asked increased in the intervention group at both timepoints. No change was shown in the control group between baseline and follow-up 1, and a decrease was shown in the total number of questions from follow-up 1 to 2. The intervention appeared to have greater effect on consultations involving advice, compared with those concerning product requests. Discussion: Communication performance improved following training. Increased information exchange is associated with guideline-compliant supply of NPMs. A substantive randomised, controlled trial is now planned to assess the intervention.This study was funded by the Chief Scientist Office, Scottish Executive Health Department
Dissipation in a rotating frame: master equation, effective temperature and Lamb-shift
Motivated by recent realizations of microwave-driven nonlinear resonators in
superconducting circuits, the impact of environmental degrees of freedom is
analyzed as seen from a rotating frame. A system plus reservoir model is
applied to consistently derive in the weak coupling limit the master equation
for the reduced density in the moving frame and near the first bifurcation
threshold. It turns out that additional interactions between momenta of system
and bath appear which have been omitted in previous studies. Explicit
expressions for the effective temperature and the Lamb-shift are given which
for ohmic baths are in agreement with experimental findings, while for
structured environments population inversion is predicted that may
qualitatively explain recent observations.Comment: 7 pages, 5 figure
Determinants of maternal care in a region of South India
A cross-sectional survey was conducted during 1993 in urban and rural areas of Karnataka State, India. The survey included 3595 currently married women aged under 35, who had at least one child under five. Nine out of ten women had at least one antenatal consultation during their most recent fertile pregnancies. Most consultations were with doctors and there was minimal use of the services provided by paramedical staff of the primary health care system. Of all respondents, 38 per cent (57% urban and 29% rural) delivered in a hospital, and a majority of institutional deliveries were in private hospitals. Surgical interventions were made in more than one-third of hospital deliveries. There was a marked imbalance between antenatal and postnatal care as fewer than one-fifth of the mothers had a postnatal checkup. The educational level, economic status and religion of the mother are significant predictors of use of maternal health services. The relationship of problems during pregnancy and delivery with subsequent health-related behaviour is also examined
Insights into unmet need in Kenya
Results from this study demonstrate that most women having unmet need for family planning in Kenya were aware of the two main contraceptive methods and a supply source, but many of the poorest, least educated women and those living in North Eastern Province were disadvantaged in this regard. Targeted expansion of access/information is a priority to meet the need of the disadvantaged populations. Kenya has one of the longest records of successful family planning programs in Africa, but this report has revealed some major defects, in particular excess reliance on two hormonal methods. Major future progress may well depend on successful popularization of other methods, particularly long-acting and permanent methods. Broadening the method mix will require simultaneous effort to stimulate the demand and increase access
The charge shuttle as a nanomechanical ratchet
We consider the charge shuttle proposed by Gorelik {\em et al.} driven by a
time-dependent voltage bias. In the case of asymmetric setup, the system
behaves as a rachet. For pure AC drive, the rectified current shows a complex
frequency dependent response characterized by frequency locking at fracional
values of the external frequency. Due to the non-linear dynamics of the
shuttle, the rachet effect is present also for very low frequencies.Comment: 4 pages, 4 figure
