Abstract

This article presents examples of the relationship between culture, dance, and the body in the fields of communication (with oneself, the community, God/deity), the social hierarchy, social values, relations between the individual and the group, and relations between genders, from the perspective of the sociology of the dance. The sociological perspective also indicates the various historical, ritual, control, and regulatory roles that traditional and modern dances play in the communities in which they arise and are performed. The second part of the text contains a case study of the Japanese ankoku butoh dance. The author presents the philosophical roots of the dance (e.g., Japanese mythology, Zen Buddhist philosophy) and the creator’s personal experiences (childhood trauma and post-war social situation) as factors that influenced the dance’s development. The example of ankoku butoh illustrates the interrelation between cultural meanings and dance movements.

Abstract

Because of the value of time, investors are interested in obtaining economic benefits rather early and at a highest return. But some investing opportunities, e.g. mineral projects, require from an investor to freeze their capital for several years. In exchange for this, they expect adequate remuneration for waiting, uncertainty and possible opportunities lost. This compensation is reflected in the level of interest rate they demand. Commonly used approach of project evaluation – the discounted cash flow analysis – uses this interest rate to determine present value of future cash flows. Mining investors should worry about project’s cash flows with greater assiduousness – especially about those arising in first years of the project lifetime. Having regard to the mining industry, this technique views a mineral deposit as complete production project where the base sources of uncertainty are future levels of economic-financial and technical parameters. Some of them are more risky than others – this paper tries to split apart and weigh their importance by the example of Polish hard coal projects at the feasibility study. The work has been performed with the sensitivity analysis of the internal rate of return. Calculations were made using the ‘bare bones’ assumption (on all the equity basis, constant money, after tax, flat price and constant operating costs), which creates a good reference and starting point for comparing other investment alternatives and for future investigations. The first part introduces with the discounting issue; in the following sections the paper presents data and methods used for spinning off risk components from the feasibility-stage discount rate and, in the end, some recommendations are presented.

Abstract

Article investigates the issue of terms of trade in energy products. The goal of this paper is to check how the terms of trade in energy fluctuate. The analysis is carried out on the example of Poland as a country which offers an interesting energy imports and exports structure. The time horizon covers the period from 2005–2015 and is extended to give the broader picture of the phenomenon wherever possible. In the research, the author uses the barter terms of trade concept. The paper has been organized in four sections. The study opens with introductory remarks presenting Polish energy situation, which is followed by a description of the terms of trade concept on the grounds of international economics. The results of the research are discussed in section three which ends with a summary and conclusions. The last part includes an additional description of study constraints and suggestions the next research steps. The statistical data used in the paper comes from national databases of the Polish Central Statistical Office and international sources such as the Organisation for Economic Cooperation and Development. Additional information on energy prices was derived from recognized branch sources such as BP Statistical Review of World Energy.

Abstract

The changes in the domestic solid fuel market (including forecasted increases in the fuel prices) and the growing requirements related to actual environmental standards, result in increased interest in renewable energy sources, such as biomass, wind and solar energy. These sources will allow to achieve reduction in the CO2 emission, and consequently – avoid environmental costs after 2020. Therefore, the development of distributed energy systems, based on the use of biomass boilers, gas boilers and high efficiency combined heat and power units, will enable the fulfillment of current standards in the field of energy efficiency and emission of pollutants to the atmosphere. It should be emphasized that the actions taken to reduce emissions (e.g. anti-smog act) will contribute to reducing coal consumption in the municipal and housing sector (households, agriculture and other customers) in favor of biomass and other renewable energy sources. The article reviews selected biomass technologies:

- fluidized, dust and grate boilers,

- straw-fired boilers,

- cogeneration systems powered by biomass,

- torrefaction and biomass carbonisation.

The mentioned technologies are characterized by a high potential of in the field of dynamic development and practical application in the coming years. Thus, they can improve difficult situation in the distributed energy sector with a capacity up to 50 MW.

Abstract

In the paper the influence of moisture content of wood on the heat losses and thermal efficiency of a boiler is analysed. The moisture content of wood has a negative effect, especially on flue gas loss. The mathematical dependence of the thermal efficiency of a boiler is presented for the following boundary conditions: the moisture content of wood 10–60%, range of temperatures of emitted flue gases from the boiler into the atmosphere 120–200 C, the emissions meeting the emission standards: carbon monoxide 250 mgm-3, fly ash 50 mgm-3and the heat power range 30–100%.

Abstract

The aim of the article is to further narrow down the accepted date of the redaction and publication of Varro’s De lingua Latina. It is argued that Varro published De lingua Latina in late 45 BC / early 44 BC, when various changes affecting the Roman calendar were in progress. In addition, the author posits that a passage in Censorinus ( De die nat. 22, 9–13) attests to Varro’s altering his views on the etymologies of month names in a subsequent work.

Abstract

The purpose of this article is to present the preparation of Project Risk Assessment Methodology and its mitigation in complex construction projects. The main text provides a summary of the approach, the method used and the findings. The conclusions have been drawn that the proper tools for quantifying risks have to be based on the criteria specific for mathematical statistic and probability or at least fuzziness. Function, which makes possible to categorize any risks into one of the five categories, is a combination of probability and the impact on one of the items: people and their safety or budget, cost, schedule and planning or quality and performance. An attempt was made to express numerically the relationship between risks impacts and their level of likelihood. Also, a method of associating the influence of projects risks impacts on the extent of the likelihood of project risk occurrence which makes possible to determine the direction and the strength of this relationship was presented.

Abstract

This study analyzes the conditional structures in the Spoken Arabic of Siirt, focusing on a series of aspects such as the topic of the sentences in such syntactical structures, the conditional markers, the verbal patterns and preverbal particles employed for introducing the conditionals and a compositional analysis of the conditional clause, with focus on the distinction between the real, open, generic, habitual and hypothetical conditionals, among other known types of the structure under study.
