The subject of this paper is an experimental analysis of a Nissan LEAF electric car equipped with 24 kWh battery, powered from the standalone photo-voltaic (PV) charging station in Gdańsk, Poland. The calculations of charging process efficiency and range of test drives were conducted in two extreme situations (winter and summer) of sunlight and road conditions. Experiments were performed in the Laboratory of Innovative Power Technologies and Integration of Innovative Energy Sources (LINTE^2) at Gdańsk University of Technology. The car was night-charged with the stationary electrochemical battery, which, in turn, was powered with PV panels during the day. The impact of sunlight and ambient temperature changes on daily urban and highway drive ranges was analysed. The efficiency of energy conversion in multiple current converters was determined.

The aim of this research is to evaluate the communication proficiency of students studying Cost and Management Accounting (CMA) and to assess whether the subject communication, as a course, is having any positive influence on students who are lacking critical thinking and literacy skills. It is necessary to analyse the factors affecting communication because of the diversity of the Durban University of Technology (DUT) students coming from different cultural, ethnic and geographic backgrounds before evaluating the communication proficiency of students. The field of accounting is broadly quantitative in nature, but Management Accounting, although a branch of this broad knowledge is more qualitative in nature. Data analysis, report writing and decision making are fundamental to Management Accounting. The target population for the study was CMA students. This population entails students enrolled for the first time in 2007 and current second and third year students. It was necessary to follow the progress of the 2007 cohort of students to establish whether students were achieving their qualification within the specified three year period as required by the CMA course and whether communication skills were an issue if they were unsuccessful. The objective to include second and third year students registered in the Department of Management Accounting at DUT in 2012 was to acquire current and pertinent information with regard to student perception on the subject relating to communication skills. An analytical type of research approach was used to conduct the study and quantitative data was collected using questionnaires and computer reports to gain an insight into the impact of communication skills as a subject in the CMA programme. The study confirmed that gender and the location of schools played a role in the academic performance of students. The overall performance between the genders revealed that female students performing slightly better than their male counterparts. English First Language (EFL) female students demonstrated much better academic performance than the EFL male students. Irrespective of language differences, if a student had an aptitude and performed well in the English Language at grade 12 or matric, the student has a better chance of being more successful with the CMA programme The number of EFL and English Second Language (ESL) students acknowledging that the English language affected them in obtaining better grades in CMA was fifty one per cent. Since the second and third year CMA students perceive that their lecturers were unaware of their poor understanding of the English language after completing the subject Communication Skills in the first year of study indicates that the subject is not having the desired affect. Both EFL and ESL students also acknowledged the vital role that Communication Skills play in education, social and economic development. This study, inter alia, recommends a screening of new students for English proficiency and providing academic support for students who have problem with literacy skills. It also recommends increasing the subject content of Communication Skills and extending the duration from one semester to two semesters.

AbstractThe article presents the results of the review of the empirical literature regarding the impact of quantitative easing (QE) on emerging markets (EMs). The subject is of interest to policymakers and researchers due to the increasingly larger role of EMs in the world economy and the large-scale capital flows occurring after 2009. The review is conducted in a systematic manner and takes into consideration different methodological choices, samples and measurement issues. The paper puts the summarized results in the context of transmission channels identified in the literature. There are few distinct methodological approaches present in the literature. While there is a consensus regarding the direction of the impact of QE on EMs, its size and durability have not yet been assessed with sufficient precision. In addition, there are clear gaps in the empirical findings, not least related to relative underrepresentation of the CEE region (in particular, Poland).

The Impact

Foreign aid has been the subject of much examination and research ever since it entered the economic armamentarium approximately 45 years ago. This was the time when the Second World War had successfully ended for the Allies in the defeat of Germany and Japan. However, a new enemy, the Soviet Union, had materialized at the end of the conflict. To counter the threat from the East, the United States undertook the implementation of the Marshal Plan, which was extremely successful in rebuilding and revitalizing a shattered Western Europe. Aid had made its impact. The book under review is by three well-known economists and is the outcome of a study sponsored by the Department of State and the United States Agency for International Development. The major objective of this study was to evaluate the impact of assistance, i.e., aid, on economic development. This evaluation however, was to be based on the existing literature on the subject. The book has five major parts: Part One deals with development thought and development assistance; Part Two looks at the relationship between donors and recipients; Part Three evaluates the use of aid by sector; Part Four presents country case-studies; and Part Five synthesizes the lessons from development assistance. Part One of the book is very informative in that it summarises very concisely the theoretical underpinnings of the aid process. In the beginning, aid was thought to be the answer to underdevelopment which could be achieved by a transfer of capital from the rich to the poor. This approach, however, did not succeed as it was simplistic. Capital transfers were not sufficient in themselves to bring about development, as research in this area came to reveal. The development process is a complicated one, with inputs from all sectors of the economy. Thus, it came to be recognized that factors such as low literacy rates, poor health facilities, and lack of social infrastructure are also responsible for economic backwardness. Part One of the book, therefore, sums up appropriately the various trends in development thought. This is important because the book deals primarily with the issue of the effectiveness of aid as a catalyst to further economic development.

The article is devoted to the subject of the goals of the climate and energy policy of the European Union, which can have both a positive, and a negative impact on the environmental and energy policies. Positive aspects are the reduction of greenhouse gas emissions, diversification of energy supplies, which should improve Europe independence from energy imports, and increasing the share of renewable energy sources (RES) in the national energy system structures. On the other hand, overly ambitious targets and actions can lead to large losses for the economies of EU Member States. The article also highlights the realities prevailing in the international arena and noncompliance of international actors with global agreements on climate protection.

Efficiency Indicators

One of efficiency indicators of grain grinders is grain granulometric composition. The basis of mixed fodder is crushed grain, the particles of which must have a leveled granulometric composition for subsequent mixing and obtaining a high-quality feed mixture. In agricultural production, hammer crushers are widely used, in which the destruction of grain occurs due to the impact of a hinged hammer. The main disadvantage of these crushers is that not the entire surface of the hammers is involved in grinding, thus reduces grinding process efficiency. A slightly different principle of material destruction is laid down in the basis of the proposed design of the shock-centrifugal grinder. Main work is performed by flat impact elements located on the rotor, which serve to accelerate crushed particles with subsequent impact of them on the bump elements. An important step in the design of new constructions of shock-centrifugal grinders is to determine size and location of the impact elements on the rotor, without which the grinding process is not possible. In the calculation method presented, the dependencies for determining the velocities and angles of a single particle flight from the surface of a flat impact element for its specified dimensions are proposed. Two variants of an impact element location on the rotor are considered and analyzed: radial and at an angle in the direction of rotor rotation. As a result of research carried out, it is noted that in the case of inclined position of an impact element on the rotor an increase in flight speed and flight angles change in crushed particles, which gives the opportunity to have a positive effect on grinding process.

The Impact

A Rhetorics of the Word is the second volume of a three-part philosophy of Christian life. It approaches Christian life as expressive of a divine calling or vocation. The word Church (ekklesia) and the role of naming in baptism indicate the fundamental place of calling in Christian life. However, ideas of vocation are difficult to access in a world shaped by the experience of disenchantment. The difficulties of articulating vocation are explored with reference to Weber, Heidegger, and Kierkegaard. These are further connected to a general crisis of language, manifesting in the degradation of political discourse (Arendt) and the impact of new communications technology on human discourse. This impact can be seen as reinforcing an occlusion of language in favour of rationality already evidenced in the philosophical tradition and technocratic management. New possibilities for thinking vocation are pursued through the biblical prophets (with emphasis on Buber’s and Rosenzweig’s reinterpretation of the call of Moses), Saint John, and Russian philosophies of language (Florensky to Bakhtin). Vocation emerges as bound up with the possibility of being name-bearers, enabling a mutuality of call and response. This is then evidenced further in ethics and poetics, where Levinas and Hermann Broch (The Death of Virgil) become major points of reference. In conclusion, the themes of calling and the name are seen to shape the possibility of love—the subject of the final part of the philosophy of Christian life: A Metaphysics of Love.
