The purpose of the study is to conduct an empirical verification of the validity of the theoretical assumption that there is an order in the structure of motives of activity, which is determined by the proportionality between the significance of each motive in their aggregate significance and is quantitatively manifested in the parameters of the hyperbolic H-distribution ranked by the parameter. The necessary conditions for solving this problem are highlighted: a) structural elements - weakly functionally dependent on each other motives; b) in the structure of motives, the functional significance of each has a quantitative expression, which must be measured through the organization of empirical research; c) the measure of the total functional significance of all motives is limited by the situation of activity and the costs of obtaining its product. On a sample of students of the first, second, third, fourth courses of technical and humanitarian specialties (N=860) using the method of subjective assessment of the significance of each of the three motives for studying at the university in their combined significance (“acquisition of knowledge”; “mastering a profession”; “obtaining a diploma”) and using a given level of the average error of approximation of empirical results with an H-distribution of 10%, it was found that statistically, at a level of error probability less than 20%, students with an average error below a given level predominate. The possible formal and substantive reasons that led to a decrease in the validity of the result are named. The interpretation of the results in the context of the “junction” of systems theory and activity theory is presented. The directions of further research in the context of the proposed model are determined.

The Mathematical Model

The paper presents the system of predicting the indicators of accreditation of technical universities based on J. Forrester mechanism of system dynamics. According to analysis of cause-and-effect relationships between selected variables of the system (indicators of accreditation of the university) there was built the oriented graph. The complex of mathematical models developed to control the quality of training engineers in Russian higher educational institutions is based on this graph. The article presents an algorithm for constructing a model using one of the simulated variables as an example. The model is a system of non-linear differential equations, the modelling characteristics of the educational process being determined according to the solution of this system. The proposed algorithm for calculating these indicators is based on the system dynamics model and the regression model. The mathematical model is constructed on the basis of the model of system dynamics, which is further tested for compliance with real data using the regression model. The regression model is built on the available statistical data accumulated during the period of the university's work. The proposed approach is aimed at solving complex problems of managing the educational process in universities. The structure of the proposed model repeats the structure of cause-effect relationships in the system, and also provides the person responsible for managing quality control with the ability to quickly and adequately assess the performance of the system.

Proposed Model

Video quality evaluation needs a combined approach that includes subjective and objective metrics, testing, and monitoring of the network. This paper deals with the novel approach of mapping quality of service (QoS) to quality of experience (QoE) using QoE metrics to determine user satisfaction limits, and applying QoS tools to provide the minimum QoE expected by users. Our aim was to connect objective estimations of video quality with the subjective estimations. A comprehensive tool for the estimation of the subjective evaluation is proposed. This new idea is based on the evaluation and marking of video sequences using the sentinel flag derived from spatial information (SI) and temporal information (TI) in individual video frames. The authors of this paper created a video database for quality evaluation, and derived SI and TI from each video sequence for classifying the scenes. Video scenes from the database were evaluated by objective and subjective assessment. Based on the results, a new model for prediction of subjective quality is defined and presented in this paper. This quality is predicted using an artificial neural network based on the objective evaluation and the type of video sequences defined by qualitative parameters such as resolution, compression standard, and bitstream. Furthermore, the authors created an optimum mapping function to define the threshold for the variable bitrate setting based on the flag in the video, determining the type of scene in the proposed model. This function allows one to allocate a bitrate dynamically for a particular segment of the scene and maintains the desired quality. Our proposed model can help video service providers with the increasing the comfort of the end users. The variable bitstream ensures consistent video quality and customer satisfaction, while network resources are used effectively. The proposed model can also predict the appropriate bitrate based on the required quality of video sequences, defined using either objective or subjective assessment.

In this paper decision-making styles, locus of control, and average grades in exams are examined as correlates of procrastination in a sample of 185 university students (mainly female students) recruited from mandatory courses for degrees in psychology and pedagogy at the University of Catania (Italy). Method: We used the Decisional Procrastination Scale (Ferrari, Johnson, & McCown, 1995), consisting of five Likert-type items useful for analyzing the procrastination; the Decision-Making Styles (Di Nuovo & Magnano, 2013), chosen for measuring the doubtfulness, delay, proxy, and no problem styles with 15 Likert-type items; the Locus of Control of Behavior Scale (Craig, Franklin, & Andrews, 1984) used to evaluate internal and external loci of control. The data were gathered through an online anonymous questionnaire and were analyzed using the multiple linear regression model to assess how styles of decision-making, locus of control, and average grades in exams affect the decision to procrastinate in university students. The main findings of this study indicate that doubtfulness and delay decision-making styles correlate with high decisional procrastination together with low average grades at university exams. Locus of control is excluded by the proposed model. Conclusions: These findings suggest pursuing a deeper investigation of the various types of procrastination and the measures used for analyzing the academic achievement in university students.

With higher operating frequencies, transmission lines are required to model global on-chip interconnects. In this paper, an accurate and efficient solution for the transient response at the far end of a transmission line based on a direct pole extraction of the system is proposed. Closed form expressions of the poles are developed for two special interconnect systems: an RC interconnect and an RLC interconnect with zero driver resistance. By performing a system conversion, the poles of an interconnect system with general circuit parameters are solved. The Newton–Raphson method is used to further improve the accuracy of the poles. Based on these poles, closed form expressions for the step and ramp response are determined. Higher accuracy can be obtained with additional pairs of poles. The computational complexity of the model is proportional to the number of pole pairs. With two pairs of poles, the average error of the 50% delay is 1% as compared with Spectre simulations. With ten pairs of poles, the average error of the 10%-to-90% rise time and the overshoots is 2% and 1.9%, respectively. Frequency dependent effects are also successfully included in the proposed method and excellent match is observed between the proposed model and Spectre simulations.

Theories Of Meaning

Abstract Dominant accounts of “speaker meaning” in post-Gricean contextualist pragmatics tend to focus on single utterances, making the theoretical assumption that the object of pragmatic analysis is restricted to cases where speakers and hearers agree on utterance meanings, leaving instances of misunderstandings out of their scope. However, we know that divergences in understandings between interlocutors do often arise, and that when they do, speakers can engage in a local process of meaning negotiation. In this paper, we take insights from interactional pragmatics to offer an empirically informed view on speaker meaning that incorporates both speakers’ and hearers’ perspectives, alongside a formalization of how to model speaker meanings in such a way that we can account for both understandings – the canonical cases – and misunderstandings, but critically, also the process of interactionally negotiating meanings between interlocutors. We highlight that utterance-level theories of meaning provide only a partial representation of speaker meaning as it is understood in interaction, and show that inferences about a given utterance at any given time are formally connected to prior and future inferences of participants. Our proposed model thus provides a more fine-grained account of how speakers converge on speaker meanings in real time, showing how such meanings are often subject to a joint endeavor of complex inferential work.

The Relationship

The Sogo bò, primarily an animal masquerade, can be distinguished from Western theatre through its use of a fluid space with shifting boundaries between spectator and performer. An oral tradition dictates the characterization, scenario, and content. The resemblance to ritual can be found in structural elements such as its repetitive nature and the use of non-realistic performance objects and motions. As in ritual, there is a clear sense of order, an evocative presentational style, and a strong collective dimension. The functional resemblance lies in the complex metaphorical expression through which relationships and values are symbolized, objectified, and embodied in a highly artistic way. Marie Kruger is an associate professor and the Chair of the Department of Drama at the University of Stellenbosch, South Africa, where puppetry is offered as a performance and research option. Her research is focused on masquerades in Africa and the various contemporary applications of puppetry in sub-Saharan Africa.

IDENTIFICATION AND CHARACTERISATION OF LANDSCAPE IN PORTUGAL –This paper presents the concepts and methodology used in the study «Identification and characterisation of landscape in continental Portugal» undertaken by theDepartment of Landscape and Biophysical Planning of the University of Evora for the General Directorate for Spatial Planning and Urban Development (DGOT-DU) at the Ministry of the Environment and Spatial Planning, between 1999 and 2001. On the one hand, the methodological approach developed is based on the methodologies used recently for the same purpose in different European countries and on the way landscape has been considered in various European documents in the last years. On the other hand, it is also based on the team’s concern to approach the landscape as an holistic entity, and to examine its various components: ecological, cultural, socio-economic and sensorial. The set aim has been to define landscape units and to characterize these units in relation to the present landscape and the recorded trends, related problems and possibilities. Thus, the cartography relative to selected variables has been combined and related to satellite images and field surveys. The results of cross-referencing all this information has than been combined with expert examination of landscape coherence and character within each unit. The assessment was completed after careful bibliographic research and consultation with regional experts. The result is a flexible approach that combines objective analysis with a more subjective assessment, which the team considered fundamental for a true understanding of landscape.

PurposeA retrospective action-research case study of one branch of the University and College Union (UCU) is used to show how threshold requirements of the Act can be systematically beaten.Design/methodology/approachThe paper responds to calls for “best practice” on how trade unions may react to member voting threshold requirements of the Trade Union Act 2016 (the Act). A broader aim is to make a theoretical contribution related to trade union organising and tactics in “get the vote out” (GTVO) industrial action organising campaigns.FindingsFindings are presented as a lead organiser's first-hand account of a successful GTVO campaign contextualised in relation to theories of organising. The findings offer “best practice” for union organisers required to beat the Act's voting thresholds and also contribute to theories surrounding trade union organising tactics.Research limitations/implicationsFurther development and adaptation of the proposed model may be required when applied to larger bargaining units and different organising contexts.Practical implicationsThe findings can inform the organising practices/tactics of trade unions in relation to statutory ballots. The findings also allow Human Resource (HR) practitioners to reflect on their approach to dealing with unions capable of mounting successful GTVO campaigns.Social implicationsThe findings have the potential to collectively empower workers, via their trade unions, to defend and further their interests in a post-financial crisis context and in the shadow of the Covid-19 pandemic.Originality/valueThis is the first known empirical account of organising to exceed voting thresholds of the Act, providing practical steps for union organisers in planning for statutory ballots. Further value lies in the paper's use of a novel first-hand account of a GTVO campaign, offering a new and first, theoretical model of organising tactics to beat the Act.
