Real Options for Risk Analysis in Estimating the Capitalization Rate

A suitable cap-rate is generally determined through an analogical process in order to estimate the value of any real estate through the capitalization of the incomes. The analogy relates to the risk and duration of similar investments. There are numerous methods to rationalize the valuation of the cap-rate. Appraisals have a certain degree of uncertainty in all these methods. This paper proposes a methodology which removes any uncertainty when evaluating the cap-rate. This is achieved through the combination of the formal logic of the Ellwood’s model and the Real Options Analysis.

EXPRESS: Not just form, not just meaning: Words with consistent form-meaning mappings are learned earlier

By leveraging Phonology-to-Semantics Consistency (PSC, Amenta, Marelli & Sulpizio, 2017), which quantifies form-meaning systematicity as the semantic similarity between a target word and its phonological nearest neighbors, wedocument a unique effect of systematicity on Age of Acquisition (AoA). This effect is also found after controlling for theeffect of neighbourhood density measured for word forms and lexical semantics and several other standard predictorsof AoA. Moreover, we show that the effect of systematicity is not reducible to iconicity. Finally, we extensively probethe reliability of this finding by testing different statistical models, analyzing systematicity in phonology and orthographyand implementing random baselines, reporting a robust, unique negative effect of systematicity on AoA, such thatmore systematic words tend to be learned earlier. We discuss the findings in the light of studies on non-arbitrary form-meaning mappings and their role in language learning, focusing on the analogical process at the interface of form andmeaning upon which PSC is based and how it could help children infer the semantics of novel words when context isscarce or uninformative, ultimately speeding up word learning.

Implementation of process liquids in well abandonment in Urikhtau field

According to the legislation of Kazakhstan Republic, during the exploration surveys on the unexplored structures, in the construction of exploration wells, the subsurface user should foresee their abandonment. Therefore, an abandonment project of the objects of hydrocarbon exploration in Urikhtau field has been developed. The completion of carbonate series and Devonian sediments was planned during the prospecting of South and East structure, which, in its turn, supposes the usage of process liquids towards the inert rocks embedded in target horizons. The abandonment of these wells supposes the usage of analogical process liquids.

Craving for Generality and Small-N Studies

This chapter addresses the question: “How can findings from case studies and ethnographies be generalized?” It advances an epistemological defence of small-N studies in the context of organization and management theory by drawing on Wittgenstein, and argues that the distinctive theoretical contribution of small-N studies stems from seeing particular cases as opportunities for further refining our conceptualization of general processes. Theorizing is an analogical process: small-N studies researchers notice analogies with processes described in other studies and, in an effort to account for the specificity of the particular case under study, draw new distinctions and thus further refine what is currently known. It is not so much analytical generalization that small-N studies aid as heuristic generalization (or analytical refinement). By doing so, the craving for generality is the craving for a clearer view. They aid generic understanding without annihilating the epistemic significance of the particular.

The Problem of Context for Similarity: An Insight from Analogical Cognition

Similarity is central for the definition of concepts in several theories in cognitive psychology. However, similarity encounters several problems which were emphasized by Goodman in 1972. At the end of his article, Goodman banishes similarity from any serious philosophical or scientific investigations. If Goodman is right, theories of concepts based on similarity encounter a huge problem and should be revised entirely. In this paper, we would like to analyze the notion of similarity with some insight from psychological works on analogical cognition. Analogical cognition compares two situations or objects in order to find similarities between them. In doing so, the analogical process sorts the different features of the two situations or objects and determines the most important ones. The analogical process is also highly sensitive to context. Context-sensitivity is desirable at some level, but it is also problematic as it leads to a computational explosion. To answer this problem, we would like to consider salience as a possible heuristic in the analogical process. We will distinguish three forms of salience: Sensory, categorical, and operational. By taking salience into account, we can introduce a shortcut into the computation of similarity and circumvent computational explosion.

Speech rhythm: a metaphor?

Is speech rhythmic? In the absence of evidence for a traditional view that languages strive to coordinate either syllables or stress-feet with regular time intervals, we consider the alternative that languages exhibit contrastive rhythm subsisting merely in the alternation of stronger and weaker elements. This is initially plausible, particularly for languages with a steep ‘prominence gradient’, i.e. a large disparity between stronger and weaker elements; but we point out that alternation is poorly achieved even by a ‘stress-timed’ language such as English, and, historically, languages have conspicuously failed to adopt simple phonological remedies that would ensure alternation. Languages seem more concerned to allow ‘syntagmatic contrast’ between successive units and to use durational effects to support linguistic functions than to facilitate rhythm. Furthermore, some languages (e.g. Tamil, Korean) lack the lexical prominence which would most straightforwardly underpin prominence of alternation. We conclude that speech is not incontestibly rhythmic, and may even be antirhythmic. However, its linguistic structure and patterning allow the metaphorical extension of rhythm in varying degrees and in different ways depending on the language, and it is this analogical process which allows speech to be matched to external rhythms.

The Influence of Geometrical Parameters on the Friction Process in the Needle Bearing

The article analyses the process of friction in the needle bearing as the function of the alterations of geometrical parameters, namely the diameter of the shaft – D, the needle – d and the bearing clearance. The change in the relation between the diameters D and d results in the change of the contact area of the friction pair; in the case of two shafts with parallel axes (the needle of the bearing and the shaft pin) the contact area, if compared with the analogical process in the ball bearing, alters significantly and leads to resistance in motion. There are two types of friction in the needle bearing: the rolling friction and the sliding friction; the analysis of the movement of the bearing elements enabled the estimation of the extent to which the sliding friction matters in the overall balance of motion resistance. The article also defines the type of wear as the function of initial clearance.

DOES P-YLIDIC RADICAL FEATURE THE YLIDIC OR RADICAL CHARACTER TOWARD FORMALDEHYDE?

Theoretical investigations are preformed on the model reaction of PH 3 CH + H 2 CO to unravel reactivity of PH 3 CH , so-called Ylide-like radical, at G3MP2 and CCSD(T)/aug-cc-pVDZ//MP2/6-311++G(d,p) level. The results indicate that P -Ylidic radical behaves differently from the P -Ylide or usual unsaturated radical toward formaldehyde. For the entrance channels, [2+2] cycloaddition to form oxaphosphetane radical INT1 is more favorable, which is an analogical process to Witting reaction of P -Ylide. So PH 3 CH shows P -Ylide character in entrance channel, which has found the support from the dual one-center frontier–orbital interaction based on Fukui's frontier–orbital theory. However, due to the radical character of INT1, it can competitively give P2 PH 3 CHCHO + H and INT2, but not Witting-type products of alkene and phosphine oxide. At last, INT2 almost can barrierlessly fragmentate to Corey-type products of ethene oxide radical and phosphine. The present study shows that PH 3 CH , Ylide-like radical, has duplicate reactivity of both P-Ylide and radical, and title reaction presents a completely new reaction mechanism, compared with previous well-known H -abstract or addition–elimination mechanism for radical- H 2 CO reactions.
