A brief analysis of the approaches to the evaluation of foundry technologies’ resource efficiency is presented. It is revealed that when evaluating resource efficiency researchers apply different criteria which do not allow them, on the one hand, to more objectively estimate the parameters and, on the other hand, to relate and compare the advantages and disadvantages of each of the assessment techniques. Representatives of one of the approaches to resource efficiency evaluation focus on determining the technological side, while representatives of the other approach emphasize the priority of the technological and economic aspects. Taking the example of analysing the problems of the technology of casting by gasified models, it has been demonstrated that the evaluation of resource efficiency cannot be unambiguous. Constant monitoring of the process is required. The authors come to conclusion that it is the method of expert evaluation that allows being more flexible in the evaluation of the resource efficiency of foundry technologies. The result of the conducted methodological assessment is the developed formula for estimating the resource efficiency of foundry technologies.

With the publication of the article ‘Cycles in symbol production’ (Peterson and Berger 1975) a discussion started concerning the advantages and disadvantages of the production of cultural goods under market conditions. The analysis by Peterson and Berger showed a negative correlation between concentration in the recording industry, on the one hand, and the diversity and innovativeness of the music, on the other. Repetition of the analysis using data from the 1980s (Burnett 1990; Lopes 1992) has shown that for this period Peterson and Berger's hypotheses should be rejected. Is there a connection between concentration and diversity and innovation? Are there cycles in symbol production? There seems to be no conclusive answer. In this article, I will attempt to clear up this matter. First, I will repeat the analysis of the relation between concentration and diversity/innovation, using the same model as Peterson and Berger, but with different definitions for the variables concentration, diversity and innovation. Then I will suggest a new model, which can be helpful in uncovering other factors influencing diversity and innovation in the music industry. I will come to that later. Let me first give the reader a brief overview of previous research.

The Brain

The concept of “brain drain” is in its origins a nationalistic concept, by which is meant a concept that visualizes economic and cultural welfare in terms of the welfare of the residents of a national state or region, viewed as a totality, and excludes from consideration both the welfare of people born in that region who choose to leave it, and the welfare of the outside world in general. Moreover, though the available statistics are far from adequate on this point, there is generally assumed to be a net flow of trained professional people from the former colonial territories to the ex-imperial European nations, and from Europe and elsewhere to North America and particularly the United States. The concept thus lends itself easily to the expression of anti-colonial sentiments on the one hand, and anti-American sentiments on the other. The expression of such sentiments can be dignified by the presentation of brain drain as a serious economic and cultural problem, by relying on nationalistic sentiments and assumptions and ignoring the principles of economics—especially the principle that in every transaction there is both a demand and a supply—or by elevating certain theoretical economic possibilities into presumed hard facts.

Assessment of competitiveness is an objective need of every business entity seeking to maintain or improve their own competitive position and make informed management decisions. The authors propose to classify the diversity of methods of assessment of the competitiveness of the enterprise through three main approaches: graphic, factor and value. In order to identify the advantages and disadvantages of each of the approaches described by the authors, the content of the main methods used in the study was analyzed. It is concluded that there is no universal tool for assessing the competitiveness of the enterprise, which is due to, on the one hand, the limited reliability and low estimates obtained by using matrix and product methods, and on the other hand, the complexity and cost of the estimates using existing multivariate models.

The article deals with the debate on the so-called “lawyer monopoly” on representation of interests in court. The Law of Ukraine "On Amendments to the Constitution of Ukraine (on Justice)" adopted on June 2016, dated June 2, 2016, No. 1401-VIII literally divided the legal community into two camps: "for" and "against" the so-called "monopoly of the Bar". It should not be denied that both supporters of this reform and its opponents have strong arguments in favor of their beliefs. In the last four years, both camps have made new arguments in support of their point of view. But every year, since the passage of the aforementioned law, calls for change have become louder. This is due to the fact that, on the one hand, the aforementioned law introduced a gradual transition to representation in all judicial instances only by a lawyer and a prosecutor, and on the other, by the fact that the proposal to exclude the rule of “lawyer monopoly” from the Constitution of Ukraine was one of the first bills of President Vladimir Zelensky. Several steps have now been taken to abolish this "monopoly" but the whole path has not yet been completed. Thus, from January 1, 2020 the Law of Ukraine 390-IX “On Amendments to Certain Legislative Acts of Ukraine on Expanding the Possibilities of Self-Representation in the Court of State Authorities, Bodies of the Autonomous Republic of Crimea, Local Self-Government Bodies and Other Legal Entities, Whatever Their Order, came into force creation ”, but the bill announced by the President No. 1013 of 29.08.2019 still remains within the walls of the Verkhovna Rada of Ukraine. This leads to some contradictions and inconsistencies in court cases regarding who can participate in litigation. In the article the author highlights the advantages and disadvantages of "lawyer's monopoly", as well as the problematic issues of the so-called transition period.

Point Of Departure

Abstract An unpublished document from late thirteenth-century Paris contains evidence of a Jewish-Christian public confrontation, on the one hand, and of Jewish-Christian economic criminal collaboration on the other. Using methods of micro-history, this article traces the story of Merot the Jew and his father-in-law, Benoait of St. Denis, who were caught attempting to smuggle merchandise by way of the River Seine. Their story is told in a verdict handed down by the parloir de Paris, the municipal judicial authority in charge of economic infractions. The parloir decreed the complete confiscation of Merot and Benoait’s merchandise on the grounds that “they were foreigners.” Taking this terminology as a point of departure, this paper tackles broader socio-economic aspects of belonging and foreignness among medieval Parisian Jews, and asks: in what ways were Jews considered “foreigners” in late thirteenth-century Paris? What were the implications of such a designation, and how did these perceptions change in the years leading up to the expulsion of 1306?

Behavioral Law And Economics

Abstract In standard economic models, two basic assumptions are made: the first, that actors are rational, and the second, that actors’ preferences are a given and exogenously determined. Behavioral economics — followed by behavioral law and economics — has questioned the first assumption. This Article challenges the second one, arguing that in many instances, social welfare should be enhanced not by maximizing satisfaction of existing preferences but by changing the preferences themselves. The Article identifies seven categories of cases where the traditional objections to intentional preference change by the state and the law lose force and argues that in these cases, such a change warrants serious consideration. It then proposes four different modes of intervention in people’s preferences, varying in intensity, on the one hand, and in the identity of their addressees, on the other, and explains the relative advantages and disadvantages of each form of intervention.
