Research on the machining process modeling of a rotational mold using CAM applications
2021
Rotational molding is a unique process, with a high growth rate, which allows the use of geometries and materials adapted to particular needs. It is superior to other manufacturing methods in terms of low cost, break-even point and size of parts that can be manufactured. Rotational molding products are often a substitute, with a lower mass, for traditionally used materials. In this scientific paper it is analyzed the recent literature related to the field of rotational molding processes. It also addresses the issue of processing a rotational mold, with the main purpose of optimizing the cutting regime. In this context, it is highlighted the way of processing the surface of the outer mold ba…
Speech technology as an experimental science: towards the comparative dynamics of Sprechkunde in Germany and Russia in the late nineteenth to early t…
2016
The article examines various resonances of the “speech technology” (Sprechkunde) current in German and Russian-Soviet context of 1900–1920s. It contains first of all a brief history of the techniques of speech in Germany, an inquiry into some psychophysical sources of the “speech technology” and a survey of the contribution of German “new rhetoric” to this movement. The Russian counterparts of this trend include the Institute of the Living Word (Institut živogo slova, 1918–1923), some Russian formalists, the scenic speech specialists and the theatre pedagogues. The conclusion summarises the historical significance of “speech technology” and its common features in Germany and Russia. It turn…
Promoting sixth graders’ credibility evaluation of Web pages: An intervention study
2020
Abstract This study investigated whether a teacher-led intervention program on online inquiry improved sixth graders' performance in a credibility evaluation task. Students (N = 342) were divided into two conditions, an intervention group (190 students) and a control group (152 students). The intervention program (21 × 45 min lessons) was implemented during a six-week course as a part of normal schoolwork. The program included explicit teaching of online inquiry skills: searching for information (3 lessons), evaluating credibility of information (3 lessons), and synthesizing information (3 lessons). In addition, the skills taught were applied in two online inquiry projects comprising 12 les…
The Role of e-Tutor Competencies in Postgraduate e-Learning Courses: Spotlight on Emotion Management
2021
The role of e-learning in the existing and challenging educational era is crucial. However, it is necessary to overcome some drawbacks such as feelings of isolation and a lack of emotional contact. In this sense, emotion management is a key driver of student satisfaction in e-learning, which is significantly related to students’ motivation, learning, cognitive strategies, self-regulation, and personality antecedents in the classroom. This article examines an online postgraduate course in financial statements auditing, describing the resources used by the e-tutor to conduct affective tutorials, reduce students’ feelings of isolation, increase student involvement, and achieve success in e-lea…
Rethinking exchange and prices
2017
Our monetary economies of production are not based upon relative exchanges described by the standard theory. Money is neither a commodity nor a positive asset; it cannot be exchanged against physical goods and services. It follows that payments do not consist of mutual transfers of commodities. In fact, each producer working for the needs for the community produces wealth for himself. Further, transactions on any markets are absolute exchanges. One of the consequences of this is that market prices do not measure wealth; rather, they are coefficients of redistribution of products.
Fundamental bounds on qubit reset
2020
Qubit reset is a basic prerequisite for operating quantum devices, requiring the export of entropy. The fastest and most accurate way to reset a qubit is obtained by coupling the qubit to an ancilla on demand. Here, we derive fundamental bounds on qubit reset in terms of maximum fidelity and minimum time, assuming control over the qubit and no control over the ancilla. Using the Cartan decomposition of the Lie algebra of qubit plus two-level ancilla, we identify the types of interaction and controls for which the qubit can be purified. For these configurations, we show that a time-optimal protocol consists of purity exchange between qubit and ancilla brought into resonance, where the maximu…
Young Scottish National Party Members’ Perceptions of Scotland and the United Kingdom
2021
This paper explores young Scottish National Party (SNP) members’ views of Scotland and the United Kingdom. It is based on the analysis of the results of an online survey and interviews with young SNP members about their political engagement and their understanding of national identity, which we carried out from 2018 to 2020. Our study focuses especially on how the members of Young Scots for Independence (YSI) and SNP Students, the youth and student wings of the SNP, perceive the Scottish nation and the UK. This paper reflects upon the way these young people define Scottishness and Scottish society. It also discusses the role of national identity in their campaign for independence. Do they w…
Amanda Boetzkes, Plastic Capitalism: Contemporary Art and the Drive to Waste
2020
L’ecologie s’est aujourd’hui imposee dans la plupart des spheres de la vie publique et intellectuelle, a tel point qu’elle apparait comme une des principales cles d’analyse du contemporain. Amanda Boetzkes s’en saisit dans un ouvrage qui cherche a comprendre la maniere dont les artistes utilisent, comprennent et donnent a voir le dechet. Apres son apparition sous sa forme contemporaine avec la revolution industrielle, le dechet est pendant longtemps relegue loin des villes et des consciences,...
Political Advertising on Facebook
2021
Parties have limited opportunities to determine the audiences of their organic communication. However, Facebook offers sophisticated advertising possibilities which enable parties to sponsor their organic messages in order to target them at selected and narrow segments of the electorate. Information on advertising activity was not available in Europe until Facebook has launched its ‘Ad Library’ right before the 2019 European Parliamentary election which provided access to all political ads and its metadata. By drawing on this data, our chapter will advance on the previous country chapters and investigate parties’ advertising activity in the 12 analysed countries with a specific focus on spo…
Kształcenie umiejętności efektywnego słuchania na lekcjach języka polskiego
2015
The aim of this article is to verify the way in which authors of school textbooks propose develop listening comprehension in Polish language lessons. The author, after discussing the specifics of listening within an interpersonal communication and detailed perceptual skills, sets objectives of improving the auditory reception in Polish language education. Subsequently, she presents an analysis of didactic tasks that are classified according to a perceptual skill which are being developed. The article finishes with the presentation of a model of developing listening comprehension that emerges from selected school textbooks.
