PIERRE BOURDIEU’S THEORY
Opis:
The article reflects on the relationship between social sphere (social standing) and cultural configurations such as tastes, practices and consumption orientations. It is raised a problem whether traditional sociological concepts (e.g. social position, class membership or status) are still relevant to a description of cultural differentiation or otherwise differences in cultural taste and consumption are losing their grounding in social stratification. As a point of departure three main arguments concerning the relationship between social structure and cultural variables were considered: i.e. a) ‘homology’ argument, b) ‘individualisation’ or ‘neotribalism’ argument, and c) ‘omnivorousness’ argument. The relevance of structuralist approach to consumption is considered from the point of view of Pierre Bourdieu’s social theory. Contrary to some current theories of mass or postmodern culture, the results of analysis sustain the view that traditional social cleavages (including social class) still play an important role in structuring consumption and lifestyles. Consumption and culture serve as a consequential site for the reproduction of social divisions, inequalities and domination.

Opis:
Covering a wide area by a large number of WiFi networks is anticipated to become very popular with Internet-of-things (IoT) and initiatives such as smart cities. Such network configuration is normally realized through deploying a large number of access points (APs) with overlapped coverage. However, the imbalanced traffic load distribution among different APs affects the energy consumption of a WiFi device if it is associated to a loaded AP. This research work aims at predicting the communication-related energy that shall be consumed by a WiFi device if it transferred some amount of data through a certain selected AP. In this paper, a forecast of the Energy consumption is proposed to be obtained using an algorithm that is supported by a mathematical model. Consequently, the proposed algorithm can automatically select the best WiFi network (best AP) that the WiFi device can connect to in order to minimize energy consumption. The proposed algorithm is experimentally validated in a realistic lab setting. The observed performance indicates that the algorithm can provide an accurate forecast to the energy that shall be consumed by a WiFi transceiver in sending some amount of data via a specific AP.

Opis:
We introduce consumption habits into a real-business-cycle setup augmented with a detailed government sector. We calibrate the model to Bulgarian data for the period following the introduction of the currency board arrangement (1999- 2018). We investigate the quantitative importance of the presence of internal consumption habits motive for the propagation cyclical fluctuations in Bulgaria. Allowing for internal habits in household’s consumption improves the model performance against data, and in addition this extended setup dominates the standard RBC model framework without habits. Therefore, the computational experiments performed in this paper suggest that habits are a quantitatively important model ingredient, which should be taken into consideration when analysing the effects of different policies in Bulgaria. This result can be viewed as an empirical validation of the habit model, and a rejection of the model without habits in the case of Bulgaria. In addition, we also demonstrate that internal habits are quantitatively more important than external habits for the Bulgarian business cycle.

Opis:
The author sets forth questions about the essence of consumption, the role of the market, and protest movements, while leaving aside overused arguments about the negative impact of consumption on civilization as a whole. She presents the most important critical understandings of consumer culture, and in particular, their strategies for resisting the dominant capitalist system. She argues that certain widely promulgated attempts at deconstruction, which are based on a ‘hegemonic’ consumer world view and announce the need to desert the market, are fairly outworn and conceptually problematic. In their place, she suggests forms of engaged participation in the market, linking consumerism with conscious, creative sufficiency and efficiency of action. Consumerism thus understood could strengthen individual freedom and broaden the extent of democratic liberties. As an accepted social logic, it could favour the creation of social ties and engagement in social life; its symbolic potential could be greater-on the principle that only engagement, rather than desertion, provides a true opportunity to influence conditions.

Opis:
Analysis of power consumption presents a very important issue for power distribution system operators. Some power system processes such as planning, demand forecasting, development, etc.., require a complete understanding of behaviour of power consumption for observed area, which requires appropriate techniques for analysis of available data. In this paper, two different time-frequency techniques are applied for analysis of hourly values of active and reactive power consumption from one real power distribution transformer substation in urban part of Sarajevo city. Using the continuous wavelet transform (CWT) with wavelet power spectrum and global wavelet spectrum some properties of analysed time series are determined. Then, empirical mode decomposition (EMD) and Hilbert-Huang Transform (HHT) are applied for the analyses of the same time series and the results showed that both applied approaches can provide very useful information about the behaviour of power consumption for observed time interval and different period (frequency) bands. Also it can be noticed that the results obtained by global wavelet spectrum and marginal Hilbert spectrum are very similar, thus confirming that both approaches could be used for identification of main properties of active and reactive power consumption time series.

Opis:
This paper studies the long-run relationship between consumption, labour income and asset wealth in Poland. Within cointegrated VAR model dynamic responses of the variables in the system to shocks are studied. In addition, series are decomposed into permanent and transitory components on the basis of the cointegrating relation found in the system. Main conclusion of this paper is that deviations of the three variables from their estimated long-run relationship are better explained with fluctuations of labour income than assets. A tentative explanation of this finding is presented. Additionally, the magnitude of the asset wealth effect in Poland is calculated and compared with other studies for European countries and for the U.S.

The predicted annual growth of energy consumption in ICT by 4% towards 2020, despite improvements and efficiency gains in technology, is challenging our ability to claim that ICT is providing overall gains in energy efficiency and Carbon Imprint as computers and networks are increasingly used in all sectors of activity. Thus we must find means to limit this increase and preserve quality of service (QoS) in computer systems and networks. Since the energy consumed in ICT is related to system load, ]this paper discusses the choice of system load that offers the best trade-off between energy consumption and QoS.We use both simple queueing models and measurements to develop and illustrate the results. A discussion is also provided regarding future research directions.

Opis:
Kitsch, as a phenomenon belonging to the domain of low culture, is today rather a subject for essayists and public discourse than for academic investigation. The very definition of kitsch has a pejorative sound. The author, however, tackles the theoretical questions related to the phenomenon and extensively discusses several ideas (including those of Hermann Broch and Abraham Moles) that are helpful in defining the concept of kitsch. She suggests an operational definition which could prove useful in social research, particularly research devoted to broader issues of consumerism or popular culture. With these goals in mind, she chooses those connotations of the concept of ‘kitsch’ that are signs of the special relation between the world of material things and consumption styles.

Opis:
This research presents a 3D FE method for the simulation of the variable reluctance stepper motor dynamics. The proposed model is used to obtain the optimal minimum energy control law that minimizes the energy injected by the controller. The method is based on the strong coupling of field - circuit equations and extended to eddy current, motion and nonlinearity problem. The linearization technique for the coupled problem is presented. Also the lamination of the motor core is considered. In the paper the open - loop control problem is analyzed. The proposed model is validated by the comparison with measurements. Next, to demonstrate the effectiveness of the proposed optimal minimum energy control method is applied. In both cases, the examination of the variable reluctance stepper motor dynamics and the steel loss in the core is presented and compared.

Although the social and cultural aspects of consumption are well known to researchers, there is lack of agreement on a theoretical and operational definition of status consumption (particularly if we take post-modernist thinking into account). With the aim of producing a better understanding of the concept, the author undertakes to answer the following questions on the basis of the existing literature: (a) Is status consumption the same as prestige consumption?; (b) How should status consumptionbe understood - as a psychological tendency, strategic action, or as an emerging relational and cultural practice?; (c) What is the relationship between status consumption and conspicuous consumption and what types of status consumption can we currently differentiate?; (d) How is status consumption changing in today’s world (and are we witnessing its disappearance in contemporary conditions)?; (e) How is status consumption measured (i.e., what is the difference between a psycho-social and a socio-cultural approach)?

Mobile devices have become an integral part of our life and provide dozens of useful services to their users. However, usability of mobile devices is hindered by battery lifetime. Energy conservation can extend battery lifetime, however, any energy management policy requires accurate prediction of energy consumption, which is impossible without reliable energy measurement and estimation methods and tools. We present an analysis of the energy measurement methodologies and describe the implementations of the internal (profiling) software (proprietary, custom) and external software-based (Java API, Sensor API, GSM AT) energy measurement methodologies. The methods are applied to measure energy consumption on a variety of mobile devices (laptop PC, PDA, smart phone). A case study of measuring energy consumption on a mobile computer using 3DMark06 benchmarking software is presented.

The article deals with a widely used method of measuring the overall efficiency of equipment (OEE), which in combination with technologies and software tools is gaining in importance. The overall efficiency of OEE equipment is a key performance metric for machines and equipment to identify hidden capacities and increase production productivity. The intensification of Industry 4.0 in traditional manufacturing companies supports and creates the conditions for their transformation into a smart factory. The integration of intelligent machines and devices with complex human-machine communication network systems requires a new direction in measuring and increasing OEE. Mass customization, resp. personalization of production raises a high need to monitor, improve and further maintain productivity. The aim of the article is to create a simulation model of the production process and test the energy consumption of selected equipment using TX Plant Simulation software with a proposal of measures to increase the OEE of the company.

Opis:
The article refers to selected elements of the sociology of Georg Simmel. It accords in general with his theory in regards to the structure of social relations, and deals in particular with the idea of sociability and the meal. The author assumes that a collective embibing of wine is a specific form of culinary consumption constituting an area for manifesting sociability. Basing himself on interviews with wine consumers, the author’s aim is to reveal the manifestations of sociability during the common consumption of this drink and to indicate the elements determining the shape and order of the social interaction: for instance, common standards of taste. As the character of such an interaction is determined by the consumption of wine, which not only imposes a certain thematic framework, but also requires the participants’ mutual adaptation, the social value of drinking can be treated as one aspect of the possible civilising effects of wine.
