The Impact

Abstract The purpose of this paper is to explore how sharecropping contracts are chosen over fixed-rent contracts. There are two concerning issues. First, theoretical explanation has been criticized for not providing a satisfactory answer to the question as to why share contracts are chosen. Second, among the existing empirical studies, there are great controversies about the impact of variance of output. Inspired by the latest insights from (Cheung, S. N. S. 2014. Economic Explanation. Hong Kong: Arcadia Press.), this paper not only provides an explanation for the choice of share contract that is suitable for empirical testing, but also solves the puzzle over variance of output.

AbstractFor over 40 years, measurements of the nucleation rates in a large number of silicate glasses have indicated a breakdown in the Classical Nucleation Theory at temperatures below that of the peak nucleation rate. The data show that instead of steadily decreasing with decreasing temperature, the work of critical cluster formation enters a plateau and even starts to increase. Many explanations have been offered to explain this anomaly, but none have provided a satisfactory answer. We present an experimental approach to demonstrate explicitly for the example of a 5BaO ∙ 8SiO2 glass that the anomaly is not a real phenomenon, but instead an artifact arising from an insufficient heating time at low temperatures. Heating times much longer than previously used at a temperature 50 K below the peak nucleation rate temperature give results that are consistent with the predictions of the Classical Nucleation Theory. These results raise the question of whether the claimed anomaly is also an artifact in other glasses.

Security is understood as one of the basic life needs of people. However, it is necessary to realize that security is a natural quality of the environment where people live and is designated as a security environment. The need for sacurity is part of implementing sacurity measures that are created in compliance with a certain level of knowledge and needs. The content of this process can be characterized as a set of answers to primary questions (What is to be protected? – protected interest, Why to protect?, What to protect from? – threats) and secondary questions (Who will provide the protection?, How will the protection be provided?, When will the protection be provided?, By means of what will the protection be provided?, What price will the protection be provided for? etc.). From this viewpoint it is necessary to pay attention primarily to the problems concerning property protection from intentional actions focusing on protecting a particular building onject. In case of building objects it is primarily about the protection of tangible and intangible properties that are part of a particular limited area (mostly a building object) that is in possession or administration of a particular state or a private subject. The issues are dealt with by legal regulations, technical standards and various technical books. These usually concentrate on a particular area, kind of a building object and/or environment. However, none of them focuses on the property protection in a complex way and does not provide a satisfactory answer to the question "How to create protection systems in view of their sufficiency, complexity and balance in the technical and economic spheres?" That is why it is a social interest to search for new standardized procedures based on exact methods by means of which it will be possible, in empiric or intuitive ways, to exactly evaluate the effectivness of the existing or proposed property protection systems, including the formal desposition of results in project solutions Keywords: Project, Project documentation, Attack, Intervention and Detection time, Resistance of a building object, Modeling, Simulating

In this paper, I reconstruct the notion of kratos as a unique and distinguishable exercise of political power. Using examples from 5th- and 4th-century Attic tragedy, Old Comedy, and forensic oratory, I show how kratos was used in Athenian cultural and political discourse to convey the irrefutability of a claim, the recognition of someone’s prevailing over another, and the sense of having the last word—all of which makes kratic power dependent upon its own continued demonstrability. I argue that the peculiarly performative character of kratos has little or no role within contemporary democratic thinking because the agency of the dēmos is largely mediated through the mechanisms of electoral success and constitutional rights. Nevertheless—and regardless of whether they are ultimately successful in achieving their stated political aims—the spontaneous, organisationally diffuse protests operating extra-institutionally under the banners of #MeToo and Black Lives Matter reveal how the attempted ‘domestication’ of kratos, and the sublimation of its peculiar power into piecemeal reform, was never a realistic or satisfactory answer for democratic discontent.

The Many

I fully appreciate and understand the nature of Dr. Bates' request. The many patients seeking treatment at our clinics make me uncomfortably aware of the problem. I wish I were able to give a more satisfactory answer. Many of the orthodontic problems, especially the severe ones, are best explained on a genetic basis. Therefore, prevention, except for a rather indelicate perusal of the family albums prior to the nuptial vows, is often not possible. In specific instances where the environment is unfavorable, such as crossbite and late thumbsuckers, the orthodontists and pedodontists can and are eliminating more extensive treatment by instituting preventive measures. However, these constituite a minority of the cases.

We improve the intuition and some ideas of G. D. Faulkner and M. C. Vipera presented in the article “Remainders of compactifications and their relation to a quotient lattice of the topology” [Proc. Amer. Math. Soc. 122 (1994)] in connection with the question about internal conditions for locally compact spaces X and Y under which βX/X ≅ βY/Y or, more generally, under which the remainders of compactifications of X belong to the collection of the remainders of compactifications of Y. We point out the reason why the quotient lattice of the topology considered by Faulkner and Vipera cannot lead to a satisfactory answer to the above question. We replace their lattice by the qoutient lattice of a new equivalence relation on a Wallman base in order to describe a method of constructing a Wallman-type compactification which allows us to deduce more complete solutions to the problems investigated by Faulkner and Vipera.

Residual Problem

The late Colin Macleod's commentary on Iliad 24 (Cambridge, 1982) has rightly received praise for its sensitivity to the nuances of Homeric language and its appreciation of the entire poem as a carefully constructed work of art. Although reluctant to accept the more radical solutions proposed by the ‘oral’ school, Macleod showed himself fully aware of the contribution made by the oral theory towards elucidating the history of the epic. Nevertheless, his commentary is concerned principally with the Iliad as we have it: a poem which is at one level a masterly re-telling of saga but at another a sublime tragedy, commiserating the sorrows inseparable from human existence and holding up for our admiration the heroes who nobly confront pain and death. I believe that much, and probably most, of the Iliad can and should be viewed in this light. The last book of all, as Macleod himself has shown, offers especially rich rewards to an interpreter who keeps in the front of his mind the overriding aims of the great poet. Yet Macleod's method, like any other single method, will never yield a fully satisfactory answer on all occasions. However the ‘definitive’ or ‘monumental’ composition of the Iliad was brought about, it formed only one stage (though from our point of view incomparably the most important stage) in the development of the Greek epic. Our Iliad cannot have been the first or the only treatment, on a large scale, of the matter of Troy.

This paper considers a hot debate ensues in attempt to find a satisfactory answer to the question, ‘Is dyslexia real or simply a myth? This especially comes after remarks from a prominent member in the modern society, the Labour Backbench MP, Mr. Graham Stringer, who asserted that dyslexia was a myth brought forth by education practitioners as cover up for their poor methods of teaching. To a similar extent, the attempt to equally provide a yielding definition for the term dyslexia has also been vain, according to different researchers, the strings of meaning and concepts attached to the term appear to fit their own descriptions and past experiences. The end result of most consequential arguments and debates leave the matter unresolved, this is despite the fact that dyslexia, a type of disorder to many, is a term that has remained quite relevant in most social contexts in recent times. This paper discusses the various arguments that are put forward by main opponents and proponents to the existence of dyslexia, and concludes that dyslexia is a myth, and it is simply a term used broadly to describe the difficulties or limited abilities in demonstrating literary skills, as identified in different people, especially leaners in education contexts
