Methodological support for estimating the level of internal communications efficiency at an enterprise

Systematic analysis of the level of communication efficiency at an enterprise ensures its increased performance. Thus, it helps to establish long-term partnership relations with contact audiences and to form consumer loyalty in the external environment. As for the internal environment of an enterprise, the analysis of communication processes can reveal the “unformalized” relations between management and subordinates, determine the degree of autonomy of the individual units, evaluate the effectiveness of the feedback between the components of the management structure. It thus helps to establish effective communication processes within the enterprise. Therefore, assessing the effectiveness of communication processes at an enterprise is of particular significance. In view of this, the purpose of the article is to develop a methodological support for estimating the level of internal communications efficiency at the enterprise. The system of indicators for the internal communications assessment has been proposed, which includes quantitative and qualitative indicators and makes it possible to comprehensively assess the state and the level of internal communications efficiency. In order to assess the level of internal communications effectiveness, the methodological approach is proposed, which is based on the use of expert methods, taking into account logical rules for constructing functions of each element attribute and the process of internal communications. This methodological approach may be used at the industrial enterprises in order to determine the level of internal communications efficiency at the operating departments or at the enterprise as a whole

Проблема психологічного впливу рекламного плакату на суспільство

The purpose of the article is a research of the modern advertising poster. As we study the poster, we study the psychological impact of the advertising poster on society. Our goal is to identify the means of the impact of modern advertising on the consumer and to evaluate the trend of development. Methodology. The methodological basis is based on the principle of a systematic approach and a comprehensive study of modern advertising. To analyze the psychological impact of the poster on the society we use: empirical and theoretical methods. We have considered the method of comparative analysis on the basis of literature on the topic of research, as well as scientific and methodological documentation. The systematization of the material is based on analysis and synthesis techniques. Scientific novelty. The scientific article investigates the means of the psychological influence of advertising on society for the first time. On the basis of our research, the definition of visual means and compositional principles of construction of advertising, substantiation of the expediency of the poster, and aesthetic appeal with the use of stylistic design, the effects of the psychological influence of the poster on the society are considered. Conclusions. To sum up, we conclude that advertising manipulates our subconscious. Analyzing the publications and trends of the poster development, it is revealed that it has long ceased to be of informative nature only and is considered as a means of influencing human consciousness. By imposing new values, it shapes attitudes towards the world and turns one into a doer of external will. Unfavorable results of social processes exacerbate stress, and work on the problem begins. As a result, it is concluded that public banners should not interpret social difficulties, but offer alternatives focused on the emotions of love, etc.Метою дослідження є розвиток сучасного рекламного плакату. Через дослідження плакату ми розглядаємо, як сучасний рекламний плакат психологічно впливає на суспільство. Нашою метою є визначення засобів впливу сучасної реклами на споживача та оцінення тенденції розвитку реклами. Методологія дослідження. За методологічну основу взято принцип системного підходу та комплексного дослідження сучасної реклами. Для аналізу психологічного впливу плакату на суспільство використано загальнонаукові методи дослідження: емпіричні та теоретичні, метод аналізу спеціалізованих ресурсів та наукових публікацій за тематикою. Нами було розглянуто метод порівняльного аналізу на основі літературних джерел за темою дослідження, а також нормативної науково-методичної документації. Систематизований матеріал здійснений на основі прийомів аналізу та синтезу. Наукова новизна. У науковій статті нами досліджено вперше, як засоби сучасного рекламного плакату психологічно впливають на суспільство. На основі нашого дослідження, визначення образотворчих засобів та композиційних принципів побудови реклами, обґрунтування доцільності рекламного плакату та естетичної привабливості, завдяки використанню стилістики дизайну, розглянуті наслідки психологічного впливу рекламного плакату на суспільство. Висновки. Підводячи підсумки, можна дійти висновку, що реклама вправно маніпулює нашою підсвідомістю. Аналізуючи публікації та дослідивши сучасні тенденції розвитку плакату, виявили, що вона давно перестала нести просто інформаційний характер і вважається одним з найсильніших засобів впливу на людську свідомість. Зараз нав`язуючи нові цінності, установи, вона формує ставлення до світу, і перетворює людину на виконавця сторонньої волі. Несприятливі результати соціальних процесів збільшують стресовість, і починається робота на проблему, її культивація. В наслідок чого,дійшли до висновку що громадські банери мають не інтерпретувати соціальні труднощі, породжуючи страхи, а пропонувати альтернативи фокусуючи увагу на емоціях любові, веселощів, патріотизму і що аналогічне

On a Kelvin-Voigt Viscoelastic Wave Equation with Strong Delay

An initial-boundary value problem for a viscoelastic wave equation subject to a strong time-localized delay in a Kelvin & Voigt-type material law is considered. Transforming the equation to an abstract Cauchy problem on the extended phase space, a global well-posedness theory is established using the operator semigroup theory both in Sobolev-valued $C^{0}$- and BV-spaces. Under appropriate assumptions on the coefficients, a global exponential decay rate is obtained and the stability region in the parameter space is further explored using the Lyapunov's indirect method. The singular limit $\tau \to 0$ is further studied with the aid of the energy method. Finally, a numerical example from a real-world application in biomechanics is presented.Comment: 34 pages, 4 figures, 1 set of Matlab code

Inquiry in University Mathematics Teaching and Learning

The book presents developmental outcomes from an EU Erasmus+ project involving eight partner universities in seven countries in Europe. Its focus is the development of mathematics teaching and learning at university level to enhance the learning of mathematics by university students. Its theoretical focus is inquiry-based teaching and learning. It bases all activity on a three-layer model of inquiry: (1) Inquiry in mathematics and in the learning of mathematics in lecture, tutorial, seminar or workshop, involving students and teachers; (2) Inquiry in mathematics teaching involving teachers exploring and developing their own practices in teaching mathematics; (3) Inquiry as a research process, analysing data from layers (1) and (2) to advance knowledge inthe field. As required by the Erasmus+ programme, it defines Intellectual Outputs (IOs) that will develop in the project. PLATINUM has six IOs: The Inquiry-based developmental model; Inquiry communities in mathematics learning and teaching; Design of mathematics tasks and teaching units; Inquiry-based professional development activity; Modelling as an inquiry process; Evalutation of inquiry activity with students. The project has developed Inquiry Communities, in each of the partner groups, in which mathematicians and educators work together in supportive collegial ways to promote inquiry processes in mathematics learning and teaching. Through involving students in inquiry activities, PLATINUM aims to encourage students` own in-depth engagement with mathematics, so that they develop conceptual understandings which go beyond memorisation and the use of procedures. Indeed the eight partners together have formed an inquiry community, working together to achieve PLATINUM goals within the specific environments of their own institutions and cultures. Together we learn from what we are able to achieve with respect to both common goals and diverse environments, bringing a richness of experience and learning to this important area of education. Inquiry communities enable participants to address the tensions and issues that emerge in developmental processes and to recognise the critical nature of the developmental process. Through engaging in inquiry-based development, partners are enabled and motivated to design activities for their peers, and for newcomers to university teaching of mathematics, to encourage their participation in new forms of teaching, design of teaching, and activities for students. Such professional development design is an important outcome of PLATINUM. One important area of inquiry-based activity is that of “modelling” in mathematics. Partners have worked together across the project to investigate the nature of modelling activities and their use with students. Overall, the project evaluates its activity in these various parts to gain insights to the sucess of inquiry based teaching, learning and development as well as the issues and tensions that are faced in putting into practice its aims and goals

Optimization of Delayed Differential Systems by Lyapunov's Direct Method

Dizertační práce se zabývá procesy, které jsou řízeny systémy zpožděných diferenciálních rovnic $$x'(t) =f(t,x_t,u),\,\,\,\, t\ge t_{0}$$ kde $t_0 \in \mathbb{R}$, funkce $f$ je definována v jistém podprostoru množiny $[t_0,\infty)\times {C}_{\tau}^{m}\times {\mathbb{R}}^r$, $m,r \in \mathbb{N}$, ${C}_{\tau}^{m}=C([-\tau,0],{\mathbb{R}}^{m})$, $\tau>0$, $x_t(\theta):=x(t+\theta)$, $\theta\in[-\tau,0]$, $x\colon [t_0-\tau,\infty)\to \mathbb{R}^{m}$. Za předpokladu $f(t,\theta_m^*,\theta_r)=\theta_m$, kde ${\theta}_m^*\in {C}_{\tau}^{m}$ je nulová vektorová funkce, $\theta_r$ a $\theta_m$ jsou $r$ a $m$-dimenzionální nulové vektory, je říd\'{i}cí funkce $u=u(t,x_t)$, $u\colon[t_0,\infty)\times {C}_{\tau}^{m}\to \mathbb{R}^{r}$, $u(t,{\theta}_m^*)=\theta_r$ určena tak, že nulové řešení $x(t)=\theta_m$, $t\ge t_{0}-\tau$ systému je asymptoticky stabilní a pro libovolné řešení $x=x(t)$ integrál \int _{t_{0}}^{\infty}\omega \left(t,x_t,u(t,x_t)\right)\diff t, kde $\omega$ je pozitivně definitní funkcionál, existuje a nabývá své minimální hodnoty v daném smyslu. Pro řešení tohoto problému byla Malkinova metoda pro obyčejné diferenciální systémy rozšířena na zpožděné funkcionální diferenciální rovnice a byla použita druhá metoda Lyapunova. Výsledky jsou ilustrovány příklady a aplikovány na některé třídy zpožděných lineárních diferenciálních rovnic.The present thesis deals with processes controlled by systems of delayed differential equations $$x'(t) =f(t,x_t,u),\,\,\,\, t\ge t_{0}$$ where $t_0 \in \mathbb{R}$, $f$ is defined on a subspace of $[t_0,\infty)\times {C}_{\tau}^{m}\times {\mathbb{R}}^r$, $m,r \in \mathbb{N}$, ${C}_{\tau}^{m}=C([-\tau,0],{\mathbb{R}}^{m})$, $\tau>0$, $x_t(\theta):=x(t+\theta)$, $\theta\in[-\tau,0]$, $x\colon [t_0-\tau,\infty)\to \mathbb{R}^{m}$. Under the assumption $f(t,\theta_m^*,\theta_r)=\theta_m$, where ${\theta}_m^*\in {C}_{\tau}^{m}$ is a zero vector-function, $\theta_r$ and $\theta_m$ are $r$ and $m$-dimensional zero vectors, a control function $u=u(t,x_t)$, $u\colon[t_0,\infty)\times {C}_{\tau}^{m}\to \mathbb{R}^{r}$, $u(t,{\theta}_m^*)=\theta_r$ is determined such that the zero solution $x(t)=\theta_m$, $t\ge t_{0}-\tau$ of the system is asymptotically stable and, for an arbitrary solution $x=x(t)$, the integral \int _{t_{0}}^{\infty}\omega \left(t,x_t,u(t,x_t)\right)\diff t, where $\omega$ is a positive-definite functional, exists and attains its minimum value in a given sense. To solve this problem, Malkin's approach to ordinary differential systems is extended to delayed functional differential equations and Lyapunov's second method is applied. The results are illustrated by examples and applied to some classes of delayed linear differential equations.
