We analyze the parallel lottery that is used to allocate hunting permits in the state of Alaska. Each participant is given tickets to distribute among lotteries for different types of items. Participants who win multiple items receive their favorite, and new winners are drawn from the lotteries with unclaimed items. When supply is scarce, equilibrium outcomes of parallel lotteries approximate a competitive equilibrium from equal incomes (CEEI), which is Pareto efficient. When supply is moderate, parallel lotteries exhibit two sources of inefficiency. First, some agents may benefit from trading probability shares. Second, outcomes may be “wasteful”: agents may receive nothing even if acceptable items remain unallocated. We bound both sources of inefficiency and show that each is eliminated by giving applicants a suitable number of tickets k: trades are never beneficial when k = 1, and waste is eliminated as [Formula: see text]. In addition, we show that the wastefulness of the k-ticket parallel lottery has some benefits: agents with strong preferences may prefer parallel lottery outcomes to those of any nonwasteful envy-free mechanism. These agents prefer small values of k, while agents with weak preferences prefer large values of k. Together, these results suggest that the k-ticket parallel lottery performs well under most circumstances and may be suitable for other settings where items are rationed.

Centrifugal Action

Abstract Liquid, supplied through a stationary tube to the inner part of a rotating cup widening toward a brim, flows viscously in a thin layer toward this brim and is then flung off, all by centrifugal action. The flow within this layer and the disintegration phenomena occurring beyond the brim have been studied, experimentally as well as theoretically. A formula has been derived for the thickness and for the radial velocity of the liquid layer within the cup, which proved to agree reasonably well with experimental results. Three essentially different types of disintegration may take place around and beyond the edge of the cup designated, respectively, by: (a) the state of direct drop formation; (b) the state of ligament formation; and (c) the state of film formation. Which one of these is realized depends upon working conditions. Transition from state (a) into (b), or of state (b) into state (c) is promoted by an increased quantity of supply, an increased angular speed, a decreased diameter of the cup, an increased density, an increased viscosity, and a decreased surface tension of the liquid. The experimental results have been expressed in relationships between relevant dimensionless groups. For the state of ligament formation a semiempirical relationship has been derived between the number of ligaments and dimensionless groups determining the working conditions of the cup. Results of drop-size measurements made for the state of ligament formation as well as for the state of film formation show that atomization by mere rotation of the cup is much more uniform than commonly achieved with pressure atomizers.

This study assesses the significance of different types of tourists to Victoria, Australia, by their relative contribution to the economy. Differential impacts are calculated using an input–output model incorporating marginal household coefficients. The analysis demonstrates that the conventional input–output model can overestimate the flow-on effects to value added, income and employment by a significant amount. It finds that domestic tourists are the largest contributor to the State economy, with day-trippers spending the greatest amount. International tourists rank last in terms of economic impacts on the state.

The commentaries on this forum’s anchor article, ‘China’s Integration into the Global Financial System: Toward a State-led Conception of Global Financial Networks’, examine how the state is shaping global financial networks (GFNs). In response to these reviews, this article discusses three common themes that bind the different commentaries: (1) different types of agency, power, and the rise of new actors; (2) the methodology behind studying state-led GFNs; and (3) the structural question of ‘Chinese exceptionalism’ as a mode of capitalism. Overall, this article affirms that the state remains central to our understanding of competitive hierarchies and firm behavior in financial networks.

The aim of study is special aspects of the efficient daily routine of students at modern educational institutions of different types, and its influence on psychophysical functions, adaptive abilities, the quality of life as well as the state of mental and somatic health of the youngsters. Materials and methods: While studying special aspects of the daily routine of students at modern educational institutions and their influence on the state of physical and mental health, the young people were observed in five modern educational establishments in Ivano-Frankivsk: Vasyl Stefanyk Precarpathian National University, Ivano-Frankivsk Finance Commercial Cooperative College named after S.Granat, Ivano-Frankivsk music school named after Denis Sichinskiy, Ivano-Frankivsk Vocational Motor Transport and Construction Lyceum № 15, Ivano-Frankivsk boarding lyceum for gifted young people from rural areas. 300 students were observed (150 female students and 150 male students). The study analyzed their educational conditions, daily routine tension, and activities during breaks, special aspects of leisure arrangements, amount of time spent on homework, subjective assessment of the level of tension of the educational process, and their projected influence on the health state of students by using static models. Results: Received results of the assessment of sanitary and hygienic conditions under which training takes place at modern educational institutions of different types, as well as conditions of after school activities of the students, by applying common methods to evaluate illumination level, microclimate, and air quality have revealed that the youngsters’ conditions at modern educational institutions are marked by absence of significant deviations from common hygienic requirements, they are similar and easily comparable and that enables defensibly and illuminatively to identify main features of influence of the different psychohygienic methods on the development of health maintaining tools and the establishment of features of the formation of functional capabilities and the basic correlates of mental and physical health. Conclusions: The educational conditions of young people in modern educational establishments can be described as not having considerable deviations from common hygienic requirements, being easily comparable and enabling to identify main influence factors of different types of psychohygienic methods of developing and implementing of healthmaintaining tools on the course of formation of the functional capabilities of the body and the development of the main adaptation reactions in young males and females.

The article is devoted to the analysis of limitation of dose load on the population as a result of radiological researches. It is especially actual and represents rather high scientific and practical interest. In this regard, it is very important to have information about the state of the dose load of the population in separate regions and to rank types of diagnostics by the amount of their contribution to the total dose of medical exposure. The aim of the work was to study the state of dose load of the population of Zaporizhzhia region due to X-ray diagnostics, to develop approaches to analysis and forecasting regarding its limitation. Analytical, statistical calculation and logical generalization methods were used in the course of the work. We used the results of studies carried out in accordance with the regional “Program for the Protection of the Population of Zaporizhzhia Region from the Effect of Ionizing Radiation. The authors analyzed scientific publications (15 sources), including 9 Ukrainian and 6 foreign on the relevance of the problem of exposure of the population caused by X-ray diagnostics. The analysis of the results allowed to determine that in 2010-2014 the radiation dose of the population of Zaporizhzhia region due to X-ray diagnostics averaged 0.92 mSv year-1, in 2015-2016 the dose increased and amounted to 0.96 mSv year-1. The proposed approach to the analysis makes it possible to summarize and model data on radiological studies of the population over a long period of time, to identify persistent trends in the contribution of different types of radiation diagnostics to the dose of medical radiation. All this is necessary for the development, first of all, of measures to reduce the frequency of radiography, its replacement by other diagnostic methods. Priority tasks aimed at reducing the dose load of the population due to X-ray examinations are proposed.

AbstractIn 1972 the state of a hanging glacier on the Weisshorn gave cause for alarm, as part of it seemed to be accelerating and a repetition of an earlier avalanche of ice seemed possible (see Röthlisberger, previous abstract). For this reason movement surveys were undertaken. The various surveying methods applied on the Weisshorn are outlined and the accuracy of the measurements is given. By least-square analysis different types of curves have been fitted to the data for velocity versus time. The best fit obtained so-far has been with hyperbolae. The confidence of extrapolations from such curves is discussed in relation to forecasts. By evaluating repeated photographs taken by an automatic camera from a single position, using a stereo plotter, the flow pattern has been established at the surface, part of the front, and one of the lateral faces of the ice mass. Changes with time caused by the deformation of the ice mass, the formation of crevasses and the crumbling away of the ice at the edge have been observed.

AbstractDictatorships are every bit as institutionally diverse as democracies, but where does this variation come from? This article argues that different types of internal rebellion influence the emergence of different types of authoritarian regimes. The critical question is whether rebel forces primarily seek to seize state power or to escape it. Regional rebellions seeking toescapethe state raise the probability of a military-dominated authoritarian regime, since they are especially likely to unify the military while heightening friction between civilian and military elites. Leftist rebellions seeking toseizethe state are more likely to give rise to civilian-dominated dictatorships by inspiring ‘joint projects’ in which military elites willingly support party-led authoritarian rule. Historical case studies of Burma, Indonesia, Malaysia and Vietnam illustrate the theory, elaborating how different types of violent conflict helped produce different types of dictatorships across the breadth of mainland and island Southeast Asia during the Cold War era.

The article is devoted to the study of the peculiarities of the experience of loneliness in young people with different types of accentuations. In this paper, the experience of loneliness is considered not only through the main components of this phenomenon (isolation, alienation, need for company, etc.), but also from the angle of the principle of casuality or the reasons why a person feels lonely. According to the data obtained as a result of our research, the need for psychocorrective work aimed at overcoming the feeling of loneliness and mastering the skills of coping with the state of loneliness in young people was justified.

Representing players' strategies in game theory has a direct impact on the players' performance. The state of art shows that automata are one of the primary techniques used for representing players' strategies and behaviors. In this paper, the author will identify different types of automata and assess their utilization in the field of game theory. Is has been found that finite automata, adaptive automata, and cellular automata are widely adopted in game theory. The utilization of finite automata is found to be limited to represent simpler players' behavior. On the other hand, adaptive automata and cellular automata are intensively applied in complex environments, where the number of interacted players is large and therefore, representing complex behaviors are needed.

Concentrates show you what to expect in a law exam, what examiners are looking for, and how to achieve extra marks. This chapter discusses the identification of actionable misrepresentations which affect the fairness of the process by which a contract was entered into, and render that contract voidable for misrepresentation (liable to be set aside and the parties restored to their pre-contractual positions). It identifies three types of misrepresentation depending on the state of mind of the misrepresentor: fraudulent, negligent, or innocent. It distinguishes between remedies available for the different types of pre-contractual statements, specifically rescission and damages for the different types of misrepresentations and briefly explains the distinction between commercial contracts and the remedies available to consumers under the CPRs 2008.
