The presented research was conducted in order to investigate the connections between developmental dyslexia and the functioning of verbatim and gist memory traces—assumed in the fuzzy-trace theory. The participants were 71 high school students (33 with dyslexia and 38 without learning difficulties). The modified procedure and multinomial model of Stahl and Klauer (simplified conjoint recognition model) was used to collect and analyze data. Results showed statistically significant differences in four of the model parameters: (a) the probability of verbatim trace recollection upon presentation of orthographically similar stimulus was higher in the control than dyslexia group, (b) the probability of verbatim trace recollection upon presentation of semantically similar stimulus was higher in the control than dyslexia group, (c) the probability of gist trace retrieval upon presentation of semantically similar stimulus was higher in the dyslexia than control group, and (d) the probability of gist trace retrieval upon target stimulus presentation (in the semantic condition) was higher in the control than dyslexia group. The obtained results suggest differences of memory functioning in terms of verbatim and gist trace retrieval between people with and without dyslexia on specific, elementary cognitive processes postulated by the fuzzy-trace theory. These can indicate new approaches in the education of persons with developmental dyslexia, focused on specific impairments and the strengths of their memory functioning. 相似文献

Background
Numerous data suggest that aerobic-type exercise improves lipoprotein-lipid profiles, cardiorespiratory fitness and body composition in young women. The aim of this study was to evaluate the biological response to high-low impact aerobic fitness among young women.Materials and methods
Thirty-four young women aged 22 (19-24) years were divided into three groups: underweight (N = 10), normal weight (N = 12) and overweight (N = 12). Aerobic capacity, anthropometry and body composition together with complete blood count and lipid profile were determined before and after completion of a 12-week-long training period.Results
The training programme caused a significant decrease in weight (by 4.3 kg, P = 0.003), body mass index (by 1.3 kg/m2, P = 0.003), free fat mass (by 2.1 kg, P = 0.002), total body water (by 0.4 kg, P = 0.036), percentage of fat (by 3 percent points, P = 0.002), all analyzed skinfolds thicknesses, as well as the lipid profile in overweight group, and no changes in normal weight group. Significant changes in weight (by 4.2 kg, P = 0.005), body mass index (by 0.9 kg/m2, P = 0.005), crus skinfold thickness (by 3.3 mm, P = 0.028), and in maximum oxygen uptake (by 2.49 mL/kg/min; P = 0.047) were observed among underweight women. No change in total blood count was observed in all groups.Conclusion
Twelve-week-long fitness training programme of two alternating styles (low and high impact) has a beneficial effect on overweight young women.Key words: body composition, physical fitness, overweight, women 相似文献3.

A 1D chain of coupled oscillators is considered, including the Duffing-type nonlinearity, viscous damping, and kinematic harmonic excitation. The equations of motion are presented in a non-dimensional form. The approximate equations for the vibrational amplitudes and phases are derived by means of the classical averaging method. A simple analysis of the resulting equations allows one to determine the conditions for the two basic synchronous steady-states of the system: the in-phase and anti-phase motions. The relations between the required excitation frequency and the natural frequencies of the abbreviated (linear) system are discussed. The validity of these predictions is examined by a series of numerical experiments. The effect of the model parameters on the rate of synchronization is analyzed. For the purpose of systematic numerical studies, the cross-correlation of time-series is used as a measure of the phase adjustment between particular oscillators. Finally, some essential issues that arise in case of the mechanical system with dry friction are indicated. 相似文献

Objective
This study was aimed at assessing the dynamics of vitronectin (VN), laminin (LN), and heparan sulfate/heparin (HS/HP) content changes during experimental burn healing.Methods
VN, LN, and HS/HP were isolated and purified from normal and injured skin of domestic pigs, on the 3rd, 5th, 10th, 15th, and 21st days following thermal damage. The wounds were treated with apitherapeutic agent (propolis), silver sulfadiazine (SSD), physiological salt solution, and propolis vehicle. VN and LN were quantified using an immunoenzymatic assay and HS/HP was estimated by densitometric analysis.Results
Propolis treatment stimulated significant increases in VN, LN, and HS/HP contents during the initial phase of study, followed by a reduction in the estimated extracellular matrix molecules. Similar patterns, although less extreme, were observed after treatment with SSD.Conclusions
The beneficial effects of propolis on experimental wounds make it a potential apitherapeutic agent in topical burn management. 相似文献5.

In this paper, a new reaching law based sliding mode control strategy for discrete time systems is introduced. Contrary to most existing approaches, the new strategy uses a sliding variable with relative degree two. It is demonstrated that the new reaching law drives the sliding variable to a narrower quasi-sliding mode band than its relative degree one equivalent, while simultaneously ensuring the desired dynamic properties of the system. Furthermore, it is shown that the smaller quasi-sliding mode band width is reflected in reduced magnitude of all state variables in the sliding mode. 相似文献

The dynamic changes in tertiary education that were observed in Poland for the last 20 years transformed the Polish educational
market and led to the immense expansion of educational institutions. The rapid increase in the number of students that continued
until 2006 is however over and Polish universities have begun to compete for their clients. Increased competition along with
the pessimistic forecasts for Poland with regard to demographic changes result in the growing demand for the knowledge on
determinants of student educational choices and satisfaction. Although the amount of studies in this field is growing, Poland
is still substantially underrepresented in the current research. The purpose of this article was to examine the underlying
factors behind the choices that Polish students make while pursuing their tertiary education. The research method that combines
focus groups’ discussions and a survey study among 1,420 business major students helped us to identify the factors behind
three phases of the decision making process: pursuing higher education; information search along with final choice of a university;
and satisfaction from chosen studies. Our research implies that decision making with regard to tertiary education is multifaceted
and longitudinal as it combines a different set of factors in each stage of the decision making process. 相似文献

Since Poland’s accession to the European Union in 2004, hundreds of thousands of Polish citizens have arrived in the UK in search of work, of which the majority landed in England and Wales. This process, although not as fast now, is still ongoing. The majority of immigrants from Poland are young people who start families and have children. Many of these children are born in the UK. For this reason, it is increasingly common for the children of Polish immigrants to be covered by the local school system. In addition to general knowledge, they also have the right to religious education and catechesis. This article presents a summary of the communities providing religious education and catechesis to Polish migrants living in England and Wales. It describes the specific features of religious education in state-run schools, Catholic schools and Polish Saturday Schools. The objectives of parish catechesis conducted by the Polish Catholic missions operating in England and Wales are also outlined. The primary objective of this discussion is to present the various options for religious education and catechesis for the children of Polish immigrants living in England and Wales. 相似文献

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode and flowchart. The eye-tracking data resulted in both qualitative (films registering the gaze paths) and quantitative measures, which allowed the detection and interpretation of the differences in the task-solving strategies between those who found the correct answer and those that did not. The results confirmed a hypothesis that use of the formal notation characteristic of a programming language for presenting algorithms is often a practical difficulty in the process of solving even simple tasks. This study opens a new direction of research; they show that eye-tracking technology can be used to optimise the educational process of learning programming. 相似文献
