The relation between cognitive and motor performance was studied in a sample of 378 children aged 5-6. Half of these children had no behavior problems; the others were selected for externalizing (38%) or internalizing problems (12%). Quantitative and qualitative aspects of motor performance were related to several aspects of cognition, after controlling for the influence of attention. No relation between global aspects of cognitive and motor performance was found. Specific positive relations were found between both aspects of motor performance, visual motor integration and working memory, and between quantitative aspects of motor performance and fluency. These findings reveal interesting parallels between normal cognitive and motor development in 5- to 6-year-old children that cannot be ascribed to attention processes. 相似文献

An algorithm for the assembly of multiple test forms is proposed in which the multiple-form problem is reduced to a series of computationally less intensive two-form problems. At each step, one form is assembled to its true specifications; the other form is a dummy assembled only to maintain a balance between the quality of the current form and the remaining forms. It is shown how the method can be implemented using the technique of O-1 linear programming. Two empirical examples using a former item pool from the LSAT are given—one in which a set of parallel forms is assembled and another in which the targets for the information functions of the forms are shifted systematically. 相似文献

Over the past ten years there has been a sweeping reform of the courses taught and qualifications awarded by Spanish universities. For that reason, an investigation was launched in 1996–97 at the University of Santiago de Compostela (in Northwest Spain) into the teaching, research and management entailed in four new degree courses: physics (years one to four), agricultural engineering (first and second years), agricultural food-processing technology (years one to three) and pharmacy. This article reports on students' opinions of the reforms in these courses, revealing dissatisfaction with facilities for practical course work, lack of connection with prospective employment, and a call for more information about courses. 相似文献

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, Mage (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed. 相似文献

Progress in microelectrode-based technologies has facilitated the development of sophisticated methods for manipulating and separating cells, bacteria, and other bioparticles. For many of these various applications, the theoretical modeling of the electrical response of compartmentalized particles to an external field is important. In this paper we address the analysis of the interaction between cells immersed in rf fields. We use an integral formulation of the problem derived from a consideration of the charge densities induced at the interfaces of the particle compartments. The numerical solution by a boundary element technique allows characterization of their dielectric properties. Experimental validation of this theoretical model is obtained by investigating two effects: (1) The influence that dipolar “pearl chaining” has on the dielectrophoretic behavior of human T lymphocytes and (2) the frequency variation of the spin and orbital torques of approaching insulinoma β-cells in a rotating field. 相似文献

This paper solves a data-driven control problem for a flow-based distribution network with two objectives: a resource allocation and a fair distribution of costs. These objectives represent both cooperation and competition directions. It is proposed a solution that combines either a centralized or distributed cooperative game approach using the Shapley value to determine a proper partitioning of the system and a fair communication cost distribution. On the other hand, a decentralized non-cooperative game approach computing the Nash equilibrium is used to achieve the control objective of the resource allocation under a non-complete information topology. Furthermore, an invariant-set property is presented and the closed-loop system stability is analyzed for the non-cooperative game approach. Another contribution regarding the cooperative game approach is an alternative way to compute the Shapley value for the proposed specific characteristic function. Unlike the classical cooperative-games approach, which has a limited application due to the combinatorial explosion issues, the alternative method allows calculating the Shapley value in polynomial time and hence can be applied to large-scale problems. 相似文献

The main objective of the Bologna Process is to create a “European space” for higher education that allows for comparability,
compatibility, and coherence between the existing systems of higher education across Europe. This objective is commonly known
as the European higher education area (EHEA). The creation of the EHEA is a new and specific challenge for higher education
in Europe, one that depends upon improved faculty development and training across Europe. The integration of Spain and other
European countries into European higher education more generally entails these challenges. In order for necessary changes
in faculty development and training to take place, university managers and policy makers must account for designing training
plans, as well the knowledge, attitudes and needs of faculty members. This investigation was undertaken with these themes
in mind. Conducted in Madrid, Spain, it included 257 professors from ten different schools of the Universidad Complutense
de Madrid. The aim of the investigation was to understand faculty knowledge and attitudes about changes in higher education
in Europe. Moreover, with an eye to helping faculty members cope with the change that is accompanying the creation of EHEA,
the investigators sought to understand the importance that faculty members place upon professional development and how current
approaches to professional development at the university level could be improved. The results indicate a degree of ignorance
regarding changes in European higher education as well as a feeling of resistance on the part of many faculty members. While
many faculty members consider knowledge of change processes and adaptability to be important qualities, faculty responses
also indicate a clear need for guidance if they are going to integrate new learning models and adequate coping strategies
into their work in higher education. 相似文献

The types of difficulties associated with career attitudes were studied using Super’s model of career maturity (1990) in a group of 620 Portuguese students from grades 9 and 12. A cluster analysis identified four styles with different patterns
of association between time perspective, attributional beliefs, self-esteem and career attitudes. The adaptive style showed
more committed career attitudes, and the other three styles—superficial, insecure and pessimistic—showed lower levels of career
maturity. Implications for career counselling are further discussed. 相似文献
