Factor-analysis was used to explore the feasibility of a multidimensional approach to the study of interpersonal attraction in an experimental context. S completed a battery of attraction items concerning an O he heard on tape. In a 2 × 2 × 2 design, O either blundered or not, was the same age or older than 5, and held similar or different opinions. These attraction ratings were then factor-analyzed and factor scores later used in analyses of variance for experimental conditions. The two factors extracted were related to socio-emotional and task-related aspects of interpersonal attraction. Interestingly enough, the Similarity dimension was significant on both of these independent factors. The study provides support for a multi-dimensional conceptualization of interpersonal attraction.

Text Reading

Literary text reading has long been a subject of empirical research. Various measures of reader differences and reader typologies were suggested, with the most prominent being studies of literary expertise, and studies employing Literary Response Questionnaire (LRQ; Miall & Kuiken, 1995). Literary expertise is difficult to define and fails to account for potential differences within non-experts. LRQ and similar dimensional approaches neglect the possibility that a salient reader typology does exist. The main goal of this study is to test whether a salient reader classification can be formed based on participant responses to questionnaires and to test how this classification corresponds to self-reported reader expertise. Based on responses from 741 participants (78.41% female, mean age = 24.31), we test the factor structure of LRQ in its Serbian translation and find moderate, acceptable fit. We also present our own Receptiveness to Literature Questionnaire (UPK) with two factors named Thorough Reading and Reading for Pleasure. Finally, we discuss relations between LRQ and UPK, offer classifications of readers formed on participant factor scores, and test the congruence between these classes and self-reported participant expertise. Our results indicate that a dimensional approach should be favored over forming categories of readers.

Conductance Level

In this study, the effects of an experimental-induced provocation on emotions and aggression were examined in 34 aggressive conduct-disordered children using a competitive reaction time paradigm. Two experimental conditions were created, an increasing provocation and a low constant provocation condition. Self-rated anger was assessed directly after provocation on a 5-point-visual scale. In addition, negative and positive emotions as well as physiological measures (heart rate and skin conductance level) were measured at baseline and after provocation. Results revealed that participants’ aggressive behaviour and subjective emotions differed as a function of the opponent’s level of provocation. Concerning physiological parameters, no significant differences were found between the experimental conditions. These results suggest that affective, but not physiological variables characterize reactive aggression in conduct-disordered children.

And Task

In the present edition “The stylistic and poetical-compositional system of a fairy tale” in 2 volumes, the author's works in the field of the study of the stylistic system of a fairy tale, carried out within the framework of an experimental direction in folklore studies, are combined. The study of the problem in this direction was undertaken by the author on the initiative of the outstanding scientist V.M. Gatsak, Doctor of Philology, Corresponding Member RAS, and was conducted over a number of years. The monograph “Oral stylistic foundations of a fairy tale. Experimental study on the abkhaz material”, which constituted 1 volume of this edition “The stylistic and poetical-compositional system of a fairy tale”, is devoted to topical problems of folklore studies, dictated by the urgent need for a comprehensive audio-visual study of folklore style. The work was carried out according to a special methodology, providing for the study of samples of oral poetry in their living existence in the light of the requirements of the experimental direction in folklore with the obligatory use of repeated recordings of fairy texts at different times, as well as film and photo documents. The aim and task of the research is to reveal the peculiarities of the style of fairy tale narration in their conditionality by the laws of preservation and transmission of traditions. The section “Appendices” contains samples of tabular analysis and intonation recording of typed repetitions, a package of film and photographic documents, a disc with a recording of the text being executed and rhythmic segments.

In recent years, soil addition with organic amendments, such as biochar and compost, has gained attention as an effective agronomic practice to sustain soil fertility, enhance plant growth and crop yield. Well known are the positive effects of compost on yield of a wide crop varieties, while both positive and negative responses are reported for biochar Therefore, the aim of the study was to verify the effect of biochar mixed with three types of compost on quanti-qualitative response of Swiss chard (Beta vulgaris L. cycla), a leafy green vegetable rich in dietary antioxidants, largely consumed worldwide. A factorial experiment in pots with two factors, including biochar (without biochar and with biochar from vine pruning residues) and compost (without compost, with compost from olive pomace, with vermicompost from cattle manure, and with compost from cattle anaerobic digestate), was setup. Two growth cycles were considered, and a set of quantitative (height of plants, number, area and fresh weight of leaves) and qualitative parameters (carotenoids, chlorophyll, total N, and NO3−content of leaves) were analyzed. Biochar decreased plant growth and NO3− leaf content; on the contrary, it increased total N leaf content, while compost improved all the considered parameters. The interactive effect of biochar and compost was evident only on total N and NO3− leaf content. In our experimental conditions, the compost showed to be the best option to improve Swiss chard growth and increase the content of phytopigments, while the biochar-compost mixtures did not produce the expected effect.

RT and its left/right difference of both biceps muscles were measured by electromyogram (EMG) in the bilateral simultaneous flexion of elbows using 11 left- and 13 right-handed subjects under four conditions which were combinations of two factors: warning signal; presence or absence of a fore-period, and position of limbs; elbow 90° or 135°. EMG-RT and its left/right difference were influenced by these factors. The effects of warning and position of limbs were not the same on the preferred and non-preferred hands. It was assumed that EMG-RTs of biceps in the preferred hand were less influenced by these experimental conditions.

Treatment Bias

A major criterion for assessing the value of any experimental model in scientific research is the degree of correspondence between its results and data from the real-life process it is designed to model. Intra-oral models aimed at predicting the anti-caries efficacy of toothpastes or other topical treatments should therefore be calibrated against treatments proven to be effective in a caries clinical trial. For this to be achieved, it is necessary that a model with high sensitivity be designed, while at the same time retaining relevance to the process to be modeled. This means that the effects of the various experimental conditions and parameters of the model on its performance must be understood. The purpose of this paper was to assess the influence of two specific factors on the performance of an in situ enamel remineralization model, which is based on human enamel slabs attached to partial dentures. The two factors are initial lesion severity and origin of enamel sample. The results indicated that initial lesion size affected whether net remineralization or net demineralization occurred during in situ treatment. Samples with an initial range of from 1500 to 2500 (ΔZ) tended more toward demineralization than did samples with ΔZ > 3500. This means that treatment groups must be well-balanced with respect to initial lesion size. Differences in initial demineralization severity between different tooth locations must also be considered so that systematic treatment bias can be avoided. The solution used in the model discussed here is based on a balanced experimental design, which allows this effect to be taken into account in the data analysis.

This paper presents an experimental study of fire suppression effectiveness with water mist containing FeCl2 additives.The investigation focuses on suppression effectiveness under various FeCl2 additives concentrations,working pressures and nozzle different height above the fire source . The experimental results show that: there is a significant impact on fire suppression effectiveness when adding FeCl2 to water mist. There is an optimum additive concentration of extinguishing fire, corresponding to the shortest extinguishing time, the least amount of water, the highest efficiency of extinguishing fire. The nozzle working pressures and nozzle position have effect on the performance of the water mist extinguishing: the greater the pressure is, the shorter water mist fire extinguishing time is. Under the same experimental conditions, the closer the water mist nozzles are to the oil pan, the shorter extinguishing time is.

In this study, activated carbons were prepared from oil palm shells by physicochemical activation. The methodology of experimental design was used to optimize the preparation conditions. The influences of the impregnation ratio (0.6–3.4) and the activation temperature between 601°C and 799°C on the following three responses: activated carbon yield (R/AC-H3PO4), the iodine adsorption (I2/AC-H3PO4), and the methylene blue adsorption (MB/AC-H3PO4) results were investigated using analysis of variance (ANOVA) to identify the significant parameters. Under the experimental conditions investigated, the activation temperature of 770°C and impregnation ratio of 2/1 leading to the R/AC-H3PO4of 52.10%, theI2/AC-H3PO4of 697.86 mg/g, and the MB/AC-H3PO4of 346.25 mg/g were found to be optimum conditions for producing activated carbon with well compromise of desirability. The two factors had both synergetic and antagonistic effects on the three responses studied. The micrographs of activated carbons examined with scanning electron microscopy revealed that the activated carbons were found to be mainly microporous and mesoporous.

An experimental study was conducted to demonstrate the value of a procedure for analyzing motor performance data. A sample of 156 subjects practiced on two instruments for motor learning while arousal data were recorded. Each set of data was submitted to an analysis of principal components and four components resulted for each set of data. Similarity coefficients were calculated for pairs of component matrices after rotation to maximum similarity. The similarity coefficients exhibit a consistent pattern which provides meaningful information concerning influence of experimental conditions on performance data.
