Difference Calculation

The research examined the calculation methods used by pupils in Grades 3–6 when they were presented with problems that could be worked out efficiently and flexibly by applying number sense. The study was conducted with a convenience sample of 179 pupils between the ages 7 years and 10 months to 12 years and 10 months. in mainstream education in Israel, who attended schools belonging to different sectors and situated in different areas of the country with varied socioeconomic profiles. The test included addition, subtraction, multiplication, and division problems that pupils were asked to solve mentally, in writing and by identifying correctly and incorrectly solved problem. Some of the problems presented pupils with opportunities to apply number sense. As expected, the research findings showed significant differences in calculation accuracy between pupils with and without learning difficulties, especially in multiplication and division tasks. Still, the performance of pupils with difficulties in the accuracy variable was above average, and there was high variance within this group. We found significant differences between pupils with and without difficulties in the calculation-speed variable in all tasks and in all calculation modalities. One of the implications is that pupils, and especially those with difficulties, should be afforded enough time to work out problems, and should be presented with tasks that would enable them to use number sense in order to retrieve prior knowledge and apply it.

Abstract Background The so-called sports consumption models are looking for the factors that influence the sports spending of households. This paper aims to examine the Hungarian, Polish and German households’ sports expenditures which can be an important indicator of physical activity and sporty lifestyle. Methods Surveying of households in three countries (Hungary, Poland and Germany) has been conducted with a self-designed questionnaire. We have used descriptive and bivariate non-parametric and parametric statistical methods: (1) χ2 test, Mann-Whitney test and Kruskal-Wallis test for checking the relationship between sociodemographic and physical activity variables and (2) independent sample t-test and ANOVA for checking the differences in sports expenditures. Results Our research concluded that men, especially previous athletes, exercise more than women and those who have no history as registered athletes. The choice of sports venues is obviously different between the countries in the sample. Members of the study population spend the most on sports services while they spend the least on sports equipment. German households have the highest spending rates compared to the other two countries. Conclusions Results are in line with our previous research findings and with other literatures. The difference in preferences of sports venues could have the reason of different supply of sports clubs or the different living standards too. It needs further researches to clear it. Material wealth, income level and sport socialisation can be a determining factor regarding the level of sports spending.

The purpose of this study is to understand among a convenience sample of 400 adults aged 60 years of age or older (1) reasons for being willing or unwilling to participate in a vaccine clinical research study and (2) overall perceptions about vaccine clinical research. A cross-sectional study using a sample of older adults residing in the metro-Atlanta area and surrounding neighborhoods was conducted. The study questionnaire contained 37 questions, including questions about socio-demographics and perceptions about clinical trial processes. Statistical analysis was conducted using logistic regression. The adjusted modeling results indicated that sex, distance to research clinic, and being informed about the research findings played a role in the likelihood of an elderly person participating in a vaccine study. Males were more likely to participate in clinical trials as compared to females (OR: 2.486; CI: 1.042–5.934). Most participants were willing to travel up to 25 miles from the research clinic. Of the respondents, 45% were unlikely to participate if the results of the current trial are not shared. Improving access to clinical trials in terms of distance traveled and ensuring streamlined processes to inform participants about the results of the trial in the future would increase willingness to participate in vaccine clinical trials. The survey could serve as a useful tool for conducting vaccine studies and other clinical trials by understanding the barriers specific to the elderly.

Research Findings

Childhood is a phase where children explore, learn and enjoy. For some children, this phase is full of difficulties. These children suffer from either developmental delays or learning difficulties. According to sources, there is a iniquitousness of 1.5-2.5% of advancing delay in kids below 2 years of age in India. Development is described into five different domains - gross motor, fine motor, speech, and language, cognitive and socio-emotional. These children need help at an early age to overcome developmental delays and for cognitive enhancement. Both parents and teachers are involved with children right from an early age, and they can devise ways to help these children. Many schools adopt 'Play' as an important activity to help these children overcome developmental delays and "toys" are mostly central to the design of such activities. The paper describes the design research for designing toys for cognitive enhancement of children with developmental delays between 2 and 5 years. In the first phase of research, the interview method was used to understand what kind of learning difficulties children face and what kind of methods are employed to teach them and understand what types of toys they are using. The sample size of 20 comprising of teachers, therapists, and pediatricians from Special schools and departments for special need children in mainstream schools was used for the interview purpose. Observational studies with children (5 different classrooms with children between 3-5 years age) were carried out to understand how children learn and use the toys. At the end of the first phase, the qualitative analysis led to the shift from learning difficulties to developmental delays. In the second phase, a survey of available products in the market was conducted to understand what types of toys are used to address these children's developmental activity. Mapping the play methods employed by the teachers and therapists to the toys' activities led to finding the Design gap. The design process incorporated the research findings. The product is designed in the form of a Toy Box with a multi-utility set of toys for cognitive enhancement in children with developmental delays. The design (three sets of toys) addresses children's communication, spatial, cognitive, gross motor & fine motor skills with developmental delays. The designed product was put through user testing twice to incorporate the findings from the testing to make the design more user-friendly for the children and the teachers, therapists, and parents.

Abstract Objective This study sought to determine if there was a difference in the months of oral contraception prescribed by physicians living in U.S. states with a 12-month supply policy compared to physicians in states without a policy. Methods We conducted an exploratory descriptive study using a convenience sample of Obstetrics & Gynecology resident physicians (n=275) in the United States. Standard bivariate analyses were used to compare the difference between groups. Results Few physicians in both groups (3.8% with a policy and 1.4% without a policy) routinely prescribed a 12-month supply of contraception. The mean coverage prescribed by providers in states with and without a policy was 2.81 and 2.07 months (p<0.05). Conclusions The majority of physicians were unaware of 12-month contraceptive supply policies and unable to correctly write a prescription for 12-months of contraception, regardless of whether they lived in a state with a 12-month contraceptive supply policy. Physician education may be needed to effectively implement 12-month contraceptive supply policies.

Purpose The purpose of this paper is to explore the effects of consumer animosity on conspicuous consumption in two research settings: Israel and Russia. The study also examines: the relationship between susceptibility to norm influence (SNI) and consumer animosity, whether SNI affects consumers’ willingness to buy (WTB) products from a country toward which they harbor animosity, and the relationship between consumer animosity and WTB in contexts differing in the level of animosity harbored toward a target country. Design/methodology/approach To probe generalizability, the hypothesized model was tested in two different contexts: Study 1 was conducted in Israel using the context of the Holocaust and Study 2 was conducted in Russia using the context of the recent political discord with the USA. A convenience sample of Israeli-Jewish (n=264) and Russian (n=259) consumers yielded a total of 523 questionnaires. Findings In both contexts, the results from the SPSS and AMOS analyses indicated a negative and significant relationship between consumer animosity and conspicuous consumption. Moreover, SNI was positively associated with consumer animosity. Finally, the study findings point to a negative association between consumer animosity and WTB, regardless of the level of animosity. Originality/value The research findings suggest that consumer animosity may be a stronger predictor for the consumption of conspicuous products than for the consumption of necessity goods.

And Performance

Background/context The National Assessment of Educational Progress (NAEP) is the only comparative assessment of academic competencies regularly administered to nationally representative samples of students enrolled in Grades 4, 8, and 12. Because NAEP is a low-stakes assessment, there are long-standing questions about the level of engagement and effort of the 12th graders who participate in the assessment and, consequently, about the validity of the reported results. Purpose/Focus This study investigated the effects of monetary incentives on the performance of 12th graders on a reading assessment closely modeled on the NAEP reading test in order to evaluate the likelihood that scores obtained at regular administrations underestimate student capabilities. Population The study assessed more than 2,600 students in a convenience sample of 59 schools in seven states. The schools are heterogeneous with respect to demographics and type of location. Intervention There were three conditions: a control and two incentive interventions. For the fixed incentive, students were offered $20 at the start of the session. For the contingent incentive, students were offered $5 in advance and $15 for correct responses to each of two randomly chosen questions, for a maximum payout of $35. All students were administered one of eight booklets comprising two reading blocks (a passage with associated questions) and a background questionnaire. All reading blocks were operational blocks released by NAEP. Research Design This was a randomized controlled field trial. Students agreed to participate without knowing that monetary incentives would be offered. Random allocation to condition was conducted independently in each school. Data Collection/Analysis Regular NAEP contractors administered the assessments and carried out preliminary data processing. Scaling of results and linking to the NAEP reporting scale were conducted using standard NAEP procedures. Findings Monetary incentives have a statistically significant and substantively important impact on both student engagement/effort and performance overall, and for most subgroups defined by gender, race, and background characteristics. For both males and females, the effect of the contingent incentive was more than 5 NAEP score points, corresponding to one quarter of the difference in the average scores between Grades 8 and 12. In general, the effect of the contingent incentive was larger than that of the fixed incentive, particularly for lower scoring subgroups. Conclusions/Recommendations There is now credible evidence that NAEP may both underestimate the reading abilities of students enrolled in 12th grade and yield biased estimates of certain achievement gaps. Responsible officials should take this into account as they plan changes to the NAEP reading framework and expand the scope of the 12th-grade assessment survey.

• Background Recent research indicates that oral measurement of body temperature is a reliable option in orally intubated patients. In situations such as protective isolation, where dedicated electronic thermometers are not available, are single-use chemical dot thermometers an acceptable alternative?• Objective To determine the accuracy of single-use chemical dot thermometers in orally intubated adult patients.• Methods Subjects included a convenience sample of 85 adult patients admitted to 1 of 2 intensive care units (surgical trauma and neuroscience). For each patient, oral temperatures were measured concurrently (within 5 minutes) with a chemical dot thermometer and an electronic thermometer. The sequence of temperature measurements was alternated with each subsequent patient. Both thermometers were placed in the same posterior sublingual pocket opposite the side of the endotracheal tube.• Results Measurements obtained with electronic and single-use chemical dot thermometers correlated strongly (r = 0.937). With the chemical dot thermometer, body temperature was overestimated in 11.8% of the measurements and underestimated in 10.8% of the measurements by 0.4°C or more. The difference between oral temperatures measured with the 2 different thermometers was not related to the patient’s age, sex, or sublingual pocket location or to the order of thermometer use.• Conclusion The chemical dot thermometer is useful and reliable for measuring body temperature of orally intubated patients. When measurements of body temperature have important consequences for decisions about treatment, clinicians should use an electronic thermometer to confirm measurements made with a chemical dot thermometer.

• Background Positioning patients is a key component of nursing care and can affect their morbidity and mortality. The Centers for Disease Control and Prevention recommend that patients receiving mechanical ventilation have the head of the bed elevated 30°to 45°to prevent nosocomial pneumonia. However, use of higher backrest positions for critically ill patients is not common nursing practice. Backrest elevation may be affected by the accuracy of nurses’ estimates of patients’ positions. • Objectives To determine the difference between nurses’ estimates of bed angles and measured bed angles and to describe the relationship between nurses’ characteristics and the accuracy of their estimates. • Methods A convenience sample of 67 nurses attending the 1999 American Association of Critical-Care Nurses National Teaching Institute and Critical Care Exposition in New Orleans, La. Each subject provided demographic information and estimated 3 bed angles. The angles were preselected by using a random number table. Summary statistics were used and were categorized according to the demographic information provided by participants. Estimated angles were correlated with measured angles, and accuracies in estimating angles were correlated with demographic characteristics. • Results Nurses were accurate in estimating bed angles (correlation, 0.8488). Demographic information, including sex, age, years of practice, years of critical care practice, basic education, highest educational level, and present position had no relationship to accuracy. • Conclusions Nurses are able to estimate backrest elevation accurately. Other explanations are needed to understand why recommendations for backrest elevation are not used in practice.

Abstract Background Due to increasing time constraints, the use of bedside presentations in resident education has declined. We examined whether patient satisfaction in the emergency department is affected when first-year residents present at the bedside with attendings. Methods We performed an observational, prospective, nonblinded study in the emergency department of a military teaching hospital. We alternately assigned first-year residents to present a convenience sample of 248 patients to the attending physician at the patient's bedside or away from the patient. We measured patient satisfaction by using the Patient Satisfaction Questionaire-18 (PSQ-18), a validated survey instrument that utilizes a Likert scale, and additional nonvalidated survey questions involving Likert and visual analog scales. Results While the median PSQ-18 score of 74 (95% confidence interval [CI], 72–76) was higher for patient satisfaction when residents made bedside presentations than that for standard presentations, 72 (95% CI, 70–74), the difference did not reach statistical significance (P  =  .33). Conclusion There was no significant difference in overall patient satisfaction between residents' bedside presentations and presentations to attendings away from the patient. Although not significant, the differences noted in PSQ-18 subscales of communication, general satisfaction, and interpersonal manner warrant further investigation. Patients did not appear to be uncomfortable with having their care discussed and with having subsequent resident education at the bedside. Future research on patient satisfaction after implementation of standardized bedside teaching techniques may help further elucidate this relationship.
