This article focuses on the films Happy Death Day (2017) and Happy Death Day 2U (2019). Both handle the spiral narrative, which is recognised by the article as a specific storytelling pattern with a protagonist stuck in an iterative segment of space, time and causality – and this protagonist is not only fully aware of this situation but also tries to deal with it. What for other unaware characters is a closed loop is for the protagonist an open experience with an odd number of turns of time spiral. The spiral narrative is known mostly from high-budget films such as Groundhog Day (1993) or Edge Of Tomorrow (2014). Nevertheless, as the article explains, it occurs in dozens of other theatrical films, VOD films, television films or television shows. However, what are the reasons why, when there is an extensive set of works to choose from, does the article take just the doublet of Happy Death Day films? (1) On their example, the article discusses the author’s general hypothesis about spiral narrative works as a series of applications of the innovative narrative schema as an aesthetic tool. Such a hypothesis consists of three broader dimensions: (a) the aesthetic dimension, i.e. the spiral schema as a part of the art work; (b) the creative dimension, i.e. the spiral schema as part of the problem-solution process of filmmaking; (c) the production dimension, i.e. the spiral schema as a part of the competition of audiovisual production. (2) An even more important reason, though, for selecting just these two films has been the fact that Happy Death Day 2U is a sequel of Happy Death Day. In the „post-classical era” of global franchises, sequels, prequels, remakes, reboots and transmedia storytellings, this does not seem to be exceptional. However, in the context of the spiral narrative, this is an unprecedented step that raises several questions the article asks.

Issues of the effective participation and cooperation of the civil society in power bodies have been a central social problem of the globe in the latest times. Although theoretical issues of participatory governance have been well developed and widely implemented, e. g. in business sector, cooperation of Power and Community pose a serious problem in the world and Ukraine in particular. The effectiveness of cooperation between Power and the civil society is downgraded by the issue the current condition of both parties, the quality of their work and their mutual trust. Also, it needs to be born in mind that this problem is a part of the triangle Power – Society – Business, and that the external environment has significant impact in the conditions of globalization. Given the Ukrainian context, it should be considered that the power system here was inherited from the Soviet Union. It is incompatible with the present-day realities, and its reform has been so far ineffective. The data from the State Statistics Service of Ukraine (SSSU) show the vast numbers of officials in local governance and central power bodies, picked up in industry-like administrative departments. The bulky apparatus of public governance being streamlined on the problem solution process in economic industries, social problems, not mentioning the ones of individual humans, can be looked at only before elections.   On the other hand, according to SSSU, Ukraine has a network of rather diverse public organizations, but their total number is small. According to Eurostat, quantitative and qualitative parameters of the civil society in Ukraine lag far behind the European ones. A diversity of goals, weak consolidation of efforts, resources and methods for solving the most important problems are factors complicating the cooperation between Power and Community. Theoretical and practical aspects of the problem related with cooperation of Power and the civil society have been elaborated in Europe since long. Advanced principles and various technologies for its solution have been proposed and implemented. The first typology of the public participation in form of “public participation staircase” was admittedly made by researcher Sh. R. Arnstein. She broke the staircase into the three levels: non-participation, symbolic participation, public power. To boost the effectiveness of collaborative action, the European community has elaborated the Code of recommended norms for the participation of the public in taking public decisions. In fact, this technology is the standard of cooperation between Power and Community in Europe.   The need for reform of the system for cooperation of power bodies with the civil society in Ukraine by use the European experience of cooperation is substantiated. The issues of goals, principles, methods and phases of cooperation between the power and the society, their advantages and drawbacks are highlighted.

This study aims to examine the relation between spatial ability and creativity in Geometry. Data was collected from 94 ninth graders. Three spatial abilities were investigated: spatial visualization, spatial relations and closure flexibility. As for students' creativity, it was examined through a multiple solution problem in Geometry focusing on three components of creativity: fluency, flexibility, and originality. The results revealed that spatial visualization predicted flexibility and originality while closure flexibility predicted all creativity components. Additionally, it was deduced that auxiliary constructions played an essential role in the problem-solution process. Finally, further study opportunities for the teaching and learning of Geometry are discussed.

Choosing the right strategy is an important condition to successfully solve math problems. Research studies often present individual types of strategies more or less separately. This study aims to determine student solutions of selected word problems in the whole context of the solution process. In this context, such nonstandard word problems combine verbal formulation and the character of nonstandard problems (impossible to be solved using an algorithm). In order to get an overall picture of the stages of word problem solution, an analysis of solving a given word problem was conducted among 171 respondents aged 10-11. The analysis was conducted in compliance with partial steps of word problem processing, as the solving of the problem was viewed from a wider perspective. The student’s reaction to the problem, working with the given information, individual forms of solution, and answer formation were recorded. In order to have a more complex idea and possibility to compare, the chosen way of solving the problem was also presented to a selected sample of 26 teachers. Available solutions were analyzed, and there were sought ways how the solution was assessed by the teachers based on selected parameters. Especially their meta-cognitive estimation of the correctness of their own solution was subject to scrutiny. Despite the fact that the respondents chose different strategies of solution (graphic, arithmetical, using judgment, etc.), it appears that the success rate of solving the given nonstandard word problem was very low. Thus, it is necessary to implement such word problems into standard math lessons, also within pre-graduate teacher preparation. Keywords: mathematics teaching, primary school mathematics, problem-solving, prospective teachers, word problem

Abstract. A considerable number of behavioral and neuroscientific studies on insight problem solving have revealed behavioral and neural correlates of the dynamic insight process; however, somatic correlates, particularly somatic precursors of creative insight, remain undetermined. To characterize the somatic precursor of spontaneous insight, 22 healthy volunteers were recruited to solve the compound remote associate (CRA) task in which a problem can be solved by either an insight or an analytic strategy. The participants’ peripheral nervous activities, particularly electrodermal and cardiovascular responses, were continuously monitored and separately measured. The results revealed a greater skin conductance magnitude for insight trials than for non-insight trials in the 4-s time span prior to problem solutions and two marginally significant correlations between pre-solution heart rate variability (HRV) and the solution time of insight trials. Our findings provide the first direct evidence that spontaneous insight in problem solving is a somatically peculiar process that is distinct from the stepwise process of analytic problem solving and can be represented by a special somatic precursor, which is a stronger pre-solution electrodermal activity and a correlation between problem solution time and certain HRV indicators such as the root mean square successive difference (RMSSD).

This article presents the rationale and methodology for developing an intrinsically safe device, namely, a hydrostatic fiber optic sensor with a position-sensitive detector for monitoring the level of oil products in large-capacity tanks at oil depots and during pumping in a raw material warehouses. This device suitable for continuous monitoring of the liquid level, based on the measurement of a hydrostatic column of liquid with automatic offset of changes in the density of the liquid. Offset is carried out by means of a displacer (a fully submerged float), inside which a housing with a position-sensitive detector (PSD) is integrated. Theoretical validation of the bellows suspension usage for a displacer is given. During filling a container with a liquid whose level is measured, liquid bellows, the movement of which is recorded by an optical triangulation sensor using the reflected infrared ray incident on the bottom of the bellows. The principle of the triangulation sensor operation is based on the geometric properties of the triangles. The pulses of infrared radiation come through a fiber optic cable. In order to measure the movement of the surface (the bottom of the bellows) by measuring the movement of the reflected beam, a position-sensitive detector is used, which is located in a remote controller. In this device for the intrinsic safety problem solution, optical inputs of a fiber optic flat cable are located in the active zone of the sensor, which is connected to the optical inputs of a position-sensitive detector, operated on the principles of photoelectric effect. The light spot moving along the sensitive zone and converted by the detector into a one-dimensional signal proportional to the distance to the object. hydrostatically applies pressure over the entire effective area of the measuring
