Purpose The goal of this research was to institute an evidence base behind commonly used elicitation materials known as binomials (e.g., “day and night”) that are commonly used for persons with aphasia (PWAs). The study explored a number of linguistic variables that could influence successful binomial completion in nonaphasic adults and PWAs. Method Thirty nonaphasic adults and 11 PWAs were asked to verbally complete 128 binomials; responses were scored by accuracy and reaction time. Binomials were coded according to the following independent variables: frequency of usage, phonological (e.g., alliteration, rhyme) and semantic (i.e., antonymy) relationships, grammatical category of the response, and number of plausible binomial completions. Results Regression analyses demonstrated that, for both groups, greater accuracy was predicted by presence of antonymy and absence of a phonological relationship. Though reaction time models differed between groups, items that elicited a greater number of response options led to longer latencies across participants. Conclusion Findings suggest that clinicians consider antonymy as well as the number of plausible responses for a given prompt when adapting the level of difficulty for their clients. Results also contribute to broader interdisciplinary research on how automatic language is processed in adults with and without neurogenic communication disorder.

AbstractThe early identification of individuals at risk of fear of falling after stroke is crucial in order to individualise preventive actions and interventions. The aim of this study was to identify the incidence of, and baseline factors in acute stroke that are associated with fear of falling at 6 months after stroke. Fear of falling was assessed by one question, which was answered by 279 of 452 eligible individuals. Univariable and multivariable logistic regression analyses were performed to determine the factors that were associated with fear of falling. The dependent variable was fear of falling at 6 months after stroke. The independent variables were related to function, activity and participation, including personal and environmental factors. Fear of falling was reported by 117 (41.9%) individuals. Poor postural control in acute stroke, measured using the modified version of the Postural Assessment Scale for Stroke Patients (odds ratio [OR]: 2.60, 95% confidence interval [CI]: 1.26–5.36), and being physically inactive prior to the stroke, measured using the Saltin-Grimby Physical Activity Scale (OR: 2.04, 95% CI: 1.01–4.12), were found to be associated with fear of falling at 6 months after stroke. The findings in this study are useful in clinical practice to optimise rehabilitation after stroke.

Noting lack of synchrony in the movement of retarded and learning disabled children led to the development of four tests requiring subjects to tap their hands in concert with a metronome. In this study the scores that 175 of these children made on the rhythmic tests were factor analyzed to obtain factor scoring coefficients; the latter were then used alone and with age in the regression analyses to predict performance on two fine and eight gross motor tasks. The proportions of total variance accounted for by the independent variables ranged from (a) .09 to .31 when the rhythmic factor-scoring coefficients were used alone and (b) .15 to .36 when age was included with the rhythmic factor-scoring coefficients.

Data were accumulated from published sources and were combined in order to estimate the effects of level of feed intake, dietary energy concentration, energy intake level and dietary forage percentage on rumen liquid turnover rates in sheep and cattle. The effects of the dietary parameters on liquid turnover rates were estimated by regression analysis, where all possible combinations of independent variables were considered. It was found that rumen liquid turnover rates increased (P < 0.05) as feed intake increased with both sheep (r = 0.610) and cattle (r = 0.715). From multiple regression analyses it was learned that the inclusion of independent variables that were related to the physical composition of the diet along with variables for intake improved the estimation of liquid turnover rates, although the independent variable related to ration composition differed between sheep and cattle. With data from sheep experiments, elevations in the digestible energy content of the diet depressed (P < 0.05) liquid turnover rate. Based upon data from cattle, decreases in the forage portion of the diet had a similar depressing (P < 0.05) effect.

Used Cooking Oil

Biopolyol is a raw material for synthesis of polyurethanes which is used as thermoset and thermoplastic materials, adhesives, rigid or non-rigid foams and also for coating. The utilization of waste edible oil as feedstock for synthesis of biopolyol has attracted some researchers. However, there is little attention focused on the application of ozone technology for synthesis of biopolyol from used cooking oil through ozonolysis reaction. Response surface methodology was performed to determine the optimal operating condition in the synthesis of biopolyol using ozone and sorbitol as a hydroxyl group source. The influence of input variables such as temperature, reaction time, molar ratio of oil to sorbitol and ozone concentration on hydroxyl value quantified was studied. The optimal condition was determined by high amount of hydroxyl value resulted from response surface method which used the experimental data. The ozonolysis reaction was conducted in a batch reactor equipped with agitator, tube sparger, thermocouple, reflux condenser and potassium iodide trap. Central composite design with four independent variables and one response variable was performed to determine the influence of independent variables on output variable of hydroxyl value of biopolyol. The hydroxyl value of polyol is a quadratic function of molar ratio of oil to methanol and a linear function of reaction temperature. The optimal operating condition was achieved at a temperature of 25℃, a reaction time of 5 hours, molar ratio of used cooking oil to sorbitol is 1:7 and ozone concentration about 4.8%.Keywords: Ozonolysis; Biopolyol; Hydroxyl value; Used cooking oil; Palm oil

This research focused on empirical connections between third-person effects and media orientations - general beliefs about news and characteristic uses of the news media. The study examined the contributions of three groups of independent variables, including political factors, media schemas, and media use, to third-person effects. Results of regression analyses suggest that each of the three groups of variables is modestly related to the magnitude of third-person effects, but none individually has great predictive power or necessarily alters third-person effects in a given news scenario. Finally, the mechanisms by which different variables influence the magnitude of third-person effects clearly vary. Overall, the results suggest only modest connections between individual differences in media orientations and the tendency to exhibit third- person effects.

Level Of Difficulty

Background: Within the assessment of frailty, self-rated health (SRH) questions remain frequently used in survey research attempting to quantify a subjective and global measure of health. Studies have largely ignored the fact that SRH questions may differ in their ability to predict level of difficulty with performing activities of daily living (ADLs)—a variance partially influenced by whether a comparative frame of reference in used in the SRH question. Specific Aim: Investigate if a Comparative-SRH (C-SRH) question with response options ranging on an adjectival scale ranging from 0 to 3; and a Non-Comparative-SRH (NC-SRH) question with an adjectival response scale from range 0 to 5; differ in their ability to predict level of difficulty in performing ADLs after accounting for demographic, psychosocial, and related health factors. Setting & Design: Cross-sectional study of community-dwelling adults (n=275; x age=68; female=54%; x BMI=31) from North Carolina participating in the Hispanic Aging Survey (HAS) were used in multivariable linear regressions to predict a granular measure of level of difficulty performing ADLs. Results: Only C-SRH has a statistically significant relationship with ADLs—where each increase in C-SRH (i.e., more positively self-rated health) is associated with a decrease in ADL level of difficult. Conclusions: Using a comparative frame of reference in SRH questions may have important implications when attempting to understand the statistical relationship between self-rated global health and physical function in the assessment of frailty in older adults.

Two Factors

Previous work has suggested that decrement in both processing speed and working memory span plays a role in the memory impairment observed in patients with schizophrenia. We undertook a study to examine simultaneously the effect of these two factors. A sample of 49 patients with schizophrenia and 43 healthy controls underwent a battery of verbal and visual memory tasks. Superficial and deep encoding memory measures were tallied. We conducted regression analyses on the various memory measures, using processing speed and working memory span as independent variables. In the patient group, processing speed was a significant predictor of superficial and deep memory measures in verbal and visual memory. Working memory span was an additional significant predictor of the deep memory measures only. Regression analyses involving all participants revealed that the effect of diagnosis on all the deep encoding memory measures was reduced to non-significance when processing speed was entered in the regression. Decreased processing speed is involved in verbal and visual memory deficit in patients, whether the task require superficial or deep encoding. Working memory is involved only insofar as the task requires a certain amount of effort. (JINS, 2011, 17, 485–493)

The economic weights of various quality traits of both Merino and crossbred wool types hive been estimated. Australian averages of clean wool prices for Australian Wool Board wool types, into which mid-side samples of fleece were classified, have been used.For each of fifteen seasons, 1953-54 to 1967-68, the mean clean wool price for each wool type was expressed as a percentage of the mean wool price for all types in that season. Rank correlations for price-type means were high between seasons, varying between 0.91 and 0.98. Further analyses were therefore performed using prices averaged for the 15 seasons. Multiple regression analyses were carried out, the dependent variable being the mean price for each fleece type, expressed as a percentage of the average price of all types for al) seasons and the independent variables being the measurement of fibre diameter, crimps per inch and length, and the subjective gradings of colour, handle, character, and quality number. For both Merino and crossbred wool types, the major determinants of price were quality number, colour, and handle, with quality number being of overwhelming importance. The remaining variables were not important as joint determinants of price, and were deleted from the analyses. Quality number, colour, and handle controlled about 81 and 86 per cent of the variation in price for Merino and crossbred wool types. It is likely that most progress in selection for wool production would be made by incorporating these findings into a selection index.
