In a ship planning can not be separated from the planning of the ship launching process. A ship can glide perfectly if it has a high enough planning time and costs. The launch process itself is divided into several ways. The choice of this method needs to be considered because it relates to the budget and preparations made. The method used is the calculation according to the numerical approach assisted by computational software. In the first calculation it is planned with the slipway launch, and then the next one is planned with the airbags that have been implemented previously. The purpose of this study is to provide analysis results as a consideration in implementing the slipway and airbag ship launching method on KM ships. Belt Nusantara 72 measuring 2000 DWT. In steps 5 to 6, both the slipway and the airbags experience a stern lift condition with a value (yVd) of 1396.97 ton.  Based on the economic analysis of the hours of people using airbags, there is a decrease in working hours by 44% when compared to the launch using a slipway. This also happened to work productivity where it was 84% more time effective. When viewed from an investment point of view, the use of slipways is actually more economical than airbag, the difference is 43% more economical using slipways. Both types of launch can be applied by looking at the economical side and the ability of each shipyard in carrying out the launching process and seeing the main size of the ship to be launched.

- The paper aims at describing the relationship between productivity, employment and GDP for the Italian provinces in the period 1995-2003. This relationship is analysed from a static, as well as from a dynamic point of view. Methods and Results The paper applies the so-called augmented fundamental identity as described by Van Ark and McGuckin. This equation allows the analysis of the differences between per capita income and productivity. The identity equation shows that the difference between GDP and productivity can be decomposed into several labour market indicators. In this way the effect of working hours, of employment, of the working age population and the effect of labour force participation on the GDP can be quantified. The identity can be calculated for levels, as well as for growth rates. Analysing the growth rates provides inside into the changes of the relationships between the involved indicators. Conclusions The analysis shows that the differences of the provincial GDP between northern and southern Italy are to a large part due to differences in the labour market indicators. If instead of the static view are analysed the dynamic development of the indicators (1995-2003), the variation of the growth rates between northern and southern Italy are much less pronounced.

The purpose of the present paper consists of two points. First, it is to show how the internal structure and the “inner logic” of science as a value sphere are formed in Max Weber’s theory. Then, relying on logical-methodological foundations proposed by Weber, the second point is to identify how the action carried out by scientists in a “vocation” mode in a situation of “value polytheism” is realized within science. Analyzing the content of recent discussions about the empirical validity and character of Weber’s argumentation in one of his central works, The Protestant Ethics and the Spirit of Capitalism, as well as about the autonomy and conceptual boundaries of Weber’s science, we draw a line of reasoning as follows. Firstly, we trace the changing of the methodological role of values in general, and the value of truth, in particular, in the “sciences of culture” in connection with the transition from the transcendental solution of Heinrich Rickert to Weber’s “value polytheism”. Secondly, we analyze how the relationship between Weber’s science, progress, and rationalization is structured. Thirdly, we explicate the mode of “vocation” in science, relying on the logical-methodological foundations proposed by Weber. Fourthly, we identify the development of Weber’s idea of the value autonomy of science. It is shown that Weber rejects the criterion of truth’s universality proposed by Rickert’s logical solution. However, the construction of ideal-typical concepts and the mechanics of “cognitive interest” described by Weber allows scientists to separate extra-scientific pragmatics from the scientific research itself. The progress of the “sciences of culture” for Weber is the differentiation and the emergence of new research approaches and the refinement of concepts. At the same time, science is not teleologically connected with “progress in general” and the rationalizing world, the configuration of which is a specific historical constellation. As associated with scientific work, “gaining the clarity” turns out to be not its own goal, but a possible effect of using scientific knowledge. The mode of “vocation” in a “value polytheism” situation forces scientists to contribute to the endless scientific progress; they formulate such ideal-types and causal explanations that seem adequate and sufficient from the point of view of their cognitive interests. The stability of science’s boundaries and its value autonomy are formed in Weber’s theory gradually; epistemological studies and the implementation of his sociology of the religion research “programme” make the difference between vocations in science and politics clear.

Previous work has shown that sensory pleasure is both the motor and the sign of optimal behaviors aimed at physiological ends. From an evolutionary psychology point of view it may be postulated that mental pleasure evolved from sensory pleasure. Accordingly, the present work tested empirically the hypothesis that pleasure signals efficacious mental activity. In Experiment 1, ten subjects played video-golf on a Macintosh computer. After each hole they were invited to rate their pleasure or displeasure on a magnitude estimation scale. Their ratings of pleasure correlated negatively with the difference par minus performance, i.e., the better the performance the greater the pleasure reported. In Experiments 2 and 3, the pleasure of reading poems was correlated with comprehension, both rated by two groups of subjects, science students and arts students. In the majority of science students pleasure was significantly correlated with comprehension. Only one arts student showed this relationship; this result suggests that the proposed relationship between pleasure and cognitive efficiency is not tautological. Globally, the results support the hypothesis that pleasure is aroused by the same mechanisms, and follows the same laws, in physiological and cognitive mental tasks and also leads to the optimization of performance.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

In the article, the author reflects the existing problems of the fight against corruption in the Russian Federation. He focuses on the opacity of the work of state bodies, leading to an increase in bribery and corruption. The topic we have chosen is socially exciting in our days, since its significance is growing on a large scale at all levels of the investigated aspect of our modern life. Democratic institutions are being jeopardized, the difference in the position of social strata of society in society’s access to material goods is growing, and the state of society is suffering from the moral point of view, citizens are losing confidence in the government, and in the top officials of the state.

The article discusses the problems of evolution and the formation of the ideology of an enlightened monarchy in Russia. In this regard, the philosophical and political ideas of Catherine the Great, as well as their theoretical and ideological premises, are analyzed. It is noted that the philosophy of education in Russia was closely connected with the concepts of Voltaire, Didro, Montesquieu, Beccaria, Bentham, their views on natural law and human freedom, humanism and the rule of law. These concepts in the philosophy of Catherine received a specific interpretation, due to the sociocultural conditions of Russia. This was manifested in the famous work of Catherine the Great “The Nakaz”, which recognized Montesquieu's argument in favor of the autocracy, but at the same time, his point of view on the separation of powers was rejected. The specificity of the doctrine of enlightened monarchy lies in the combination of liberal and conservative values, which form eclectic forms. This was the dialectic of the supreme power, the difference between the enlightened monarchy and the ideology of absolutism. The article also notes that education in Russia is associated with fundamental socio-political reforms, processes of secularization of culture. At this time, the natural and human sciences are developing. The changes positively influenced the development of medicine, beautification of towns and public education. Also considered are the views on the autocracy of the opposition nobility intelligentsia: A. N. Radishchev and noted that his criticism of the autocracy was determined by an alternative cultural policy, proceeding from the protection of the interests of the people. The doctrine of enlightened monarchy is characterized by internal worldview inconsistency and political inconsistency, which did not allow solving the pressing social problems of the establishment of legal state, democratization of society and the abolition of serfdom.


Dreyfus argues that there is a basic methodological difference between the natural sciences and the social sciences, a difference that derives from the different goals and practices of each. He goes on to argue that being a realist about natural entities is compatible with pluralism or, as he calls it, “plural realism.” If intelligibility is always grounded in our practices, Dreyfus points out, then there is no point of view from which one can ask about or provide an answer to the one true nature of ultimate reality. But that is consistent with believing that the natural sciences can still reveal the way the world is independent of our theories and practices.


This book is the second volume of the two-volume The Oxford Handbook of the Economics of Sports which includes articles by nearly all of the important authors in the quickly growing field of sports economics. The two volumes consider in depth the ways that economics and sports interact with each other. To start with, economic analysis has helped with the understanding of many of the different institutions in sports. Secondly, quality data about individual productivity, salaries, career histories, teamwork, and managerial behavior has been useful in helping economists study topics as varied as the economics of discrimination, salary dispersion, and antitrust policy. The volumes are also rich from the point of view of the sports fan. Every major team sport is covered, and many interesting comparisons can be made especially between the North American League organization and the European-style promotion and relegation leagues. Golf, NASCAR, college athletics, women's sports, the Olympics, and even bowling are represented in these pages.

The high water intake and wastewater discharge of slaughterhouses have been a concern for many years. One neglected factor in previous research is allocating the water footprint (WF) to beef production’s different products and by-products. The objective of this article was to estimate the WF of different cattle breeds at a slaughterhouse and cutting plant and allocate it according to the different cuts (products) and by-products of beef based on the value fraction of each. The results indicated a negative relationship between the carcass weight and the processing WF when the different breeds were compared. Regarding a specific cut of beef, a kilogram of rib eye from the heaviest breed had a processing WF of 614.57 L/kg, compared to the 919.91 L/kg for the rib eye of the lightest breed. A comparison of the different cuts indicated that high-value cuts had higher WFs than low-value cuts. The difference between a kilogram of rib eye and flank was 426.26 L/kg for the heaviest breed and 637.86 L/kg for the lightest breed. An option to reduce the processing WF of beef is to lessen the WF by slaughtering heavier animals. This will require no extra investment from the slaughterhouse. At the same time, the returns should increase as the average production inputs per kilogram of output (carcass) should reduce, as the slaughterhouse will process more kilograms.
