The experimental study was made to get additional empirical evidence to show how thecognitive style in its field dependence-independence dimension differentiate studentswith different aptitude to solve chemistry problems. Twenty eight students participated,11 female and 17 male, average age seventeen. The test used was a set of simpleproblems, to obtain information about level of perception and selected strategy to get anappropriate solution.

This research aims to test the influence of tax sanction and obedience pressure on tax compliance. By applying a 2x2 between-subject factorial experiment method, this research has found the empirical evidence that taxpayers tend to be more tax-compliant when the tax sanction is high rather than low. Next, when taxpayers tend to be more non-compliant when they receive obedience pressure from their superior rather than not. Lastly, from the interaction test between tax sanction and obedience pressure variables, the researcher found empirical evidence that shows that, when given high tax sanctions, a taxpayer will have higher tax compliance rate when they do not receive obedience pressure compared with when they receive obedience pressure. This research has a practical implication that obedience pressure from a superior is a key that could potentially reduce tax compliance rate because, although there are low or high sanctions, if there are any obedience pressure, then the tax compliance rate will be low.

In this paper attention has been called to the debate on whether field dependence/independence displays two distinctive cognitive styles on different levels of spatial-visual ability. The effectiveness of testing instruments for young children is questioned for they may not measure the same dimensions as the instruments used for older children and adults. The field dependence/independence dimension has generated widespread interest and stimulated much research into the effects of training on the construct. A condensed review of the literature is presented. From this basis, the gaps in the literature are discussed. The educational implications are discussed with a warning that all training programs should be monitored carefully.

Forty-three Sprague-Dawley and 43 Wistar rats were given reward training for 40 trials in a Y-maze. On the next 20 trials, control groups were continued under the same training procedure, and 50% shock trials were introduced in the training of the remaining rats. For the extinction training, the reward was shifted to the opposite arm and 50% shock was continued for the no-delay and 30-sec. delay shock groups. The most significant results were that in the 30-sec. delay groups, the delay helped the Sprague-Dawley rats reverse in a minimum number of trials, whereas the Wistar rats showed strong indications of response stereotypy. The findings with respect to the Sprague-Dawley rats supported the empirical evidence on the effectiveness of delay in overcoming response persistence and the findings on the Wistar rats supported the empirical evidence on omission in punishment. The difference in response to punishment between the two albino strains emphasizes the need for experimental study of strain factors. Experiments should be repeated with several animal strains to remedy over-generalization from single strains and to help elaborate our understanding of the interaction present between punishment and strains.

This experimental study investigates the differential effects of three conditions (nonnegotiated premodified input, negotiation without “pushed output” [Swain, 1985], and negotiation plus pushed output) on L2 learners' vocabulary comprehension and acquisition (receptive and productive). Analyses of variance performed on the data indicated that: (a) negotiated interaction had a positive effect on the comprehension of L2 words; (b) only negotiated interaction that incorporated pushed output appeared to have promoted both receptive and productive acquisition of words as well as an increase in productive word retention; and (c) negotiated interaction plus output did not promote receptive acquisition more than negotiation without output, but it was more effective in promoting productive acquisition. The findings of this study provide empirical evidence for the important role of negotiation in facilitating the comprehension and acquisition of L2 vocabulary, which suggests that output plays a key role within the negotiation process for productive lexical acquisition.

PurposeVisual stimulation affects the taste of food and beverages. This study aimed to understand how latte art affects coffee consumption by collecting participants' brainwave data and their taste responses.Design/methodology/approachSeventy subjects participated in a two-stage experiment. Electroencephalography (EEG) was employed to measure brainwave activity. With an interval of one week, each stage involved coffee consumption with and without latte art. The responses to the taste of the coffee were also collected for analysis.FindingsSignificant differences were found in the participants' alpha and beta brainwave bands. When drinking coffee with latte art, the participants' alpha bands were significantly lower, whereas the beta bands were higher. These findings were supported by Bayesian statistics. A significant increase was found in the participants' taste of sweetness and acidity with latte art, and Bayesian statistics confirmed the results for sweetness although the evidence on the increase in acidity was anecdotal. No difference was found in the taste of bitterness.Originality/valueThis study highlights the effect of latte art on coffee consumption. The authors analysed the empirical evidence from this two-stage experimental study in the form of the participants' brainwave data and their responses to taste. This study's original contribution is that it explored the crossmodal effects of latte art on consumers' taste of coffee from a neuroscientific perspective. The results of this study can provide empirical evidence on how to effectively use latte art in practical business environments.

A new way for determining the magnetostriction characteristics of a composite multiferroics using the magnetoelectric response of the structure is proposed. It is shown that integral from the field dependency of linear magnetoelectric coefficient is the magnetostriction characteristic of the structure. The results of an experimental study of the physical properties of bulk composites based on lead zirconate titanate and ferrite-nickel spinel are presented. Based on the field dependence of the magnetoelectric voltage coefficient, magnetostriction curves of composite structures with a content of ferrospinel of 10–70% were obtained.


Some years ago de Haas and van Alphen showed that the variation of the magnetization of bismuth with field, which is linear at ordinary temperatures, assumes a complicated periodic character at the temperature of liquid hydrogen (20º K) and below. Later, Peierls was able to show theoretically that such an effect was to be expected in general, but that it should be marked only for metals of a special electronic structure such as bismuth. Since this non-linear field dependence of magnetization (which we shall refer to as the de Haas-van Alphen effect) is interesting in itself as a new phenomenon for diamagnetics, and in the light of Peierls's theory could be expected to give information about the electronic structure of bismuth, we have made a further experimental study of it, first confirming the features already found by de Haas and van Alphen and then examining its temperature dependence in greater detail, and and influence of allowing other elements with the bismuth.

The research’s objective is to evaluate the differential effect that a metacognitive scaffolding for information web searches has on learning achievement of high school students with different cognitive style in the field dependence and independence dimension and on learning style in the dimension proposed by Honey and Alonso known as CHAEA. One hundred and four students from a school in the city of Bogotá, Colombia participated in the study. The research was quasi-experimental and was conducted with three 10th-grade groups, which worked with three scaffolding versions: fixed, optional, and without scaffolding. A multivariate analysis of covariance established that the fixed scaffolding favored learning achievement. Regarding cognitive style in the field dependence and independence dimension, the findings allow to conclude that the field independent students exhibited better academic performances in the presence of a fixed scaffolding when compared with the field dependent students. In addition, a positive interaction was identified between cognitive style and the scaffolding that drives learning achievement. However, learning style did not have any effect on academic achievement.
