AbstractAnalogies with rational mechanics played a pivotal role in the search for formal models in economics. In the period between the two world wars, a small group of mathematical economists tried to extend this view from statics to dynamics. The main result was the extensive application of calculus of variations to obtain a dynamic representation of e-conomic variables. This approach began with the contributions put forward by Griffith C.Evans, a mathematician who in the first phase of his scientific career published wi-dely in economics. Evans' research was further developed by his student, Charles Roos. At the international level, this dynamic approach found its main followers in Italy, within the Paretian tradition. During the 1930s, Luigi Amoroso, the leading exponent of the Paretian School, made major contributions along with his student, Giulio La Volpe that anticipated the concept of temporary equilibrium. The analysis of the application of the calculus of variations to economic dynamics in the interwar period raises a set of questions on the application of mathematics designed to study mechanics and physics to economics

Holistic Representation

Building Information Modelling (BIM) is deemed to shape the future of the construction sector across the world. At present, the lack of BIM in tertiary education has been the rising concern around the world as the demand for BIM talent increases. The current landscape suggests that few pedagogic researches have been undertaken to advance BIM education, particularly in Malaysia. BIM implementation could only be possible by identifying the potential barriers, which is a basic pre-requisite for successful adoption of BIM. Unfortunately, previous studies on the barriers of BIM adoption have often based on theoretical constructs, which are deterministic in nature. The methodology used could not portray a conclusive correlation of causal relations among the variables, creating difficulty in developing holistic and workable solutions. Therefore, this study aims to develop a methodology that provides a dynamic representation of the barriers in implementing BIM in tertiary education. The methodology combines both the deterministic (feedback from questionnaire survey) and dynamic approach (causal loop diagram). Data was first collected and analysed through a questionnaire survey administered among lecturers from selected Malaysian universities. Following that, a dynamic systems approach (causal loop diagram) was used to demonstrate the complex nature and interrelationship of the barriers for a more holistic representation. Results from the deterministic analysis has suggested barriers that relate to technology, while findings from the dynamics has identified the people aspect as the core barrier for BIM adoption. This study has contributed in establishing a methodology that integrates the dynamic approach with the deterministic data towards providing a more holistic representation of a system that further enables the identification of holistic solutions that would address the core barriers inhibiting the implementation of BIM education, particularly at Malaysian Universities.

Abstract On the occasion of the 50th anniversary of the passing of the Transylvanian musician Nicolae Bretan (1887-1968), known during the interwar period due to his complex field of activity (interpreter, director, conductor, composer), we consider it necessary to elaborate a study that is critical for several reasons. Starting with the dilemmatic comments existent in the current bibliography, we propose, on the one hand, to systematize the information regarding the reception of his personality in the context of the age in which he lived and worked, and on the other hand, to outline the premises that generated the appearance of controversial writings, but especially to question their effects on the deformed stylistic perception of the musician at national and international level. We consider that this is one of the ways in which the “phenomenon of Bretan’s rebirth” can be objectively reevaluated, appreciating the existence and real contributions of a minor musician, who, although endowed with talent, could not be in the same compositional direction that included national models (George Enescu, Mihail Jora, Paul Constantinescu), are comparable to those in the universal space of the first half of the 20th century.

Syndrome Analysis

Neuropsychology, as a science, studies possible relations between psychological processes and brain in cases of normality and diverse pathologies. Such kind of relations might be established and understood by different manners. A.R. Luria proposed unique and particular way of approach by brain units. Such conceptionis not completely understood and even less used in practice of diagnosis and rehabilitation today. Neuropsychologists provide assessments of isolated functions by help of psychometric procedures. The judgment of diagnosis refers to such terms as “attention or memory disorders”, dyslexia and so on. All these terms are really far away from the conception of systemic and dynamic representation of human actions infunctional brain systems. Same or worse is the situation with rehabilitation directed to isolated operations as conductive exercises for isolated functions. The objective of our report is to share opinion of application of Luria’s methodology of syndrome analysis. Procedures of systemic functional diagnosis must conduct to systemic procedures in rehabilitation. An example of qualitative assessment of adolescent patient withbrain injury is presented. Goals, stages and examples of formation of actions in rehabilitation with results are provided. Psychological conceptions of stage by stage formation and orientation base of action and its usage for rehabilitation is taken into account. We conclude that systemic and dynamic approach in neuropsychology might be conducted in reality of assessment and rehabilitation. We discuss the necessity of establishment of bridges between psychological theory of actions instead of functions and systemic representation of actions by functional brain systems. Keywords: neuropsychological rehabilitation, concepts of neuropsychology, functional diagnosis, qualitative neuropsychology, brain injury rehabilitation.

Abstract. The Balloon-Analogue Risk Task (BART; Lejuez et al., 2002 ) is one of the most popular behavioral tasks suggested to assess risk-taking in the laboratory. Previous research has shown that the conventionally computed score is predictive, but neglects available information in the data. We suggest a number of alternative scores that are motivated by theories of risk-taking and that exploit more of the available data. These scores can be grouped around (1) risk-taking, (2) task performance, (3) impulsive decision making, and (4) reinforcement sequence modulation. Their theoretical rationale is detailed and their validity is tested within the nomological network of risk-taking, deviance, and scholastic achievement. Two multivariate studies were conducted with youths (n = 435) and with adolescents/young adults (n = 316). Additionally, we tested formal models suggested for the BART that decompose observed behavior into a set of meaningful parameters. A simulation study with parameter recovery was conducted, and the data from the two studies were reanalyzed using the models. Most scores were reliable and differentially predictive of criterion variables and may be used in basic research. However, task specificity and the generally moderate validity do not warrant use of the experimental paradigm for diagnostic purposes.

Abstract. Adopting a within-person perspective, we theorize why ingratiation use directed toward an authority figure increases over time and for whom. We posit that as the appraisal event draws closer, the salience of achieving good evaluations increases, leading to an increasing use of ingratiation. We further propose that the increase will be stronger for individuals with low relative to high self-esteem. Participants were 349 students enrolled in a small-group, tutor-led management course. Data were collected in three bi-weekly waves and analyzed using random coefficient modeling. Results show that ingratiation use increased as time to the evaluation decreased, and low self-esteem students ingratiated more as time progressed. We conclude that ingratiation use varies as a function of contextual and inter-individual differences.

Abstract. Several empirical investigations have explored whether observers prefer to sort sets of multidimensional stimuli into groups by employing one-dimensional or family-resemblance strategies. Although one-dimensional sorting strategies have been the prevalent finding for these unsupervised classification paradigms, several researchers have provided evidence that the choice of strategy may depend on the particular demands of the task. To account for this disparity, we propose that observers extract relational patterns from stimulus sets that facilitate the development of optimal classification strategies for relegating category membership. We conducted a novel constrained categorization experiment to empirically test this hypothesis by instructing participants to either add or remove objects from presented categorical stimuli. We employed generalized representational information theory (GRIT; Vigo, 2011b , 2013a , 2014 ) and its associated formal models to predict and explain how human beings chose to modify these categorical stimuli. Additionally, we compared model performance to predictions made by a leading prototypicality measure in the literature.
