Nonlinear resultant theory of shells accounting for thermodiffusion

The complete nonlinear resultant 2D model of shell thermodiffusion is developed. All 2D balance laws and the entropy imbalance are formulated by direct through-the-thickness integration of respective 3D laws of continuum thermodiffusion. This leads to a more rich thermodynamic structure of our 2D model with several additional 2D fields not present in the 3D parent model. Constitutive equations of elastic thermodiffusive shells are discussed in more detail. They are formulated from restrictions imposed by the resultant 2D entropy imbalance according to Coleman–Noll procedure extended by a set of 2D constitutive equations based on heuristic assumptions.

Not Wanted: On Scharp’s Solution to the Liar

Kevin Scharp argues that the concept of truth is defective, and is therefore unable to play its intended role in natural language truth-conditional semantics. As such, for this theoretical purpose, Scharp constructs two replacements: ascending truth and descending truth. Scharp applies the resultant theory, AD semantics, to the liar sentence, thereby obtaining a novel solution to the liar paradox. The aim of the present paper is fourfold. First, I show that, contrary to Scharp’s claims, AD semantics in fact yields an inconsistency when applied to standard liar sentences. Second, I diagnose the problem: AD semantics mishandles negation. I propose an alternative treatment, resulting in what I call AD* semantics. Third, I show that AD* semantics gives Scharp the resources required to respond to an alleged revenge paradox that has been raised against his view. Finally, I argue that, these consequences notwithstanding, it remains unclear whether AD* semantics provides an adequate account of alethic paradoxes more generally.

Can there be a Finite Interpretation of the Kantian Sublime?

Kant’s account of the sublime makes frequent appeals to infinity, appeals which have been extensively criticised by commentators such as Budd and Crowther. This paper examines the costs and benefits of reconstructing the account in finitist terms. On the one hand, drawing ona detailed comparison of the first and third Critiques, I argue that the underlying logic of Kant’s position is essentially finitist. I defend the approach against longstanding objections, as well as addressing recent infinitist work by Moore and Smith. On the other hand, however, I argue that finitism faces distinctive problems of its own: whilst the resultant theory is a coherent and interesting one, it is unclear in what sense it remains an analysis of the sublime. I illustrate the worry by juxtaposing the finitist reading with analytical cubism.

Combining Unmergeables: A Methodological Framework for Axiomatic Fusion of Qualitative Design Theories

The proposed methodological framework concerns axiomatic theory fusion (ATF) of non-additive engineering design theories. ATF includes seven steps: (i) semantic discretization of the composite theories, (ii) deriving epistemological entities by logical/semantic analysis, (iii) establishing and representation of relations among all relevant epistemological entities, (iv) combining the inter- theoretical epistemological entities of the component theories, (v) deriving propositions based on the combined set of epistemological entities, (vi) transcription of the epistemological entities and propositions into a textual/visual theory description, and (vii) validation of the resultant theory in application contexts. The proposed framework makes ATF an effective, content independent methodology for fusing component theories, no matter if they are descriptive, explanatory, predictive or controlling in nature. ATF methodology requires professional comprehension and rigor from the researchers. It is necessary to justify the logical correctness and practical validity of the target theory in the specific application context.

Charting the moral life courses: A theory of moral development in U.S. evangelical and mainline Protestant cultures

Drawing from qualitative analyses of interviews, ethnographic data, and a review of interdisciplinary literature, this manuscript puts forth a theory of moral life course narratives among U.S. evangelical and mainline Protestants. This theory delineates the relationship between religious worldviews and conceptions of moral behaviors, and the manner in which these worldviews and attendant moral conceptions change across the life course for community members. Grounded theory analyses of 32 participants’ divinity-based moral discourses were interpreted in conjunction with their worldviews, as well as church, home, and school contexts. Analyses indicated that evangelical children highlighted their moral transgressions because they regarded themselves as still quite close to a sinful birth. Evangelical adults, who had been saved and were moving toward God, temporally and spiritually distanced themselves from the morally wrong deeds of their youth. Meanwhile, mainline children and adolescents rarely reasoned about their moral experiences in terms of divinity. This finding is understood in light of their church’s emphasis on developing an individualized relationship with God over time. The study and resultant theory elaborate cultural constructions and transmissions of moral life course narratives that, in turn, provide a framework for understanding when, why, and how divinity enters into moral meaning making for cultural community members. We conclude by advocating for theoretical, methodological, and analytical approaches that expose the cultural nature of developmentally dynamic moral selves.

A Grounded Theory of Persistence in a Limited-Residency Doctoral Program

Approximately 50% of doctoral students in social science, humanities, and educational doctoral programs fail to earn their Ph.D. This number is 10% to 15% higher for students enrolled in online or limited-residency programs. Using in-depth interviews and qualitative data analysis techniques, this grounded-theory study examined participants’ recollections of their experience as students in a limited-residency doctoral program and their reasons for withdrawal while working on their dissertation. The study was guided by the central question “What is the nature of the participants’ experiences of doctoral attrition in a limited-residency doctoral program?” The resultant theory clarified relationships between attrition and a support issues (i.e., advisor support, dissertation process support and program office support). The theoretical model helps identify steps faculty and administration may take in order to reduce high levels of attrition. Recommendations for effective doctoral education practices from existing literature are supported in the findings of this study.

Implementation of Novel Technique for Selective Harmonic Elimination in Multilevel Inverters Based on ICA

Eliminating the specific harmonics especially low-order harmonics of the output voltage of 9-level inverter using SHE-PWM control scheme is investigated. Harmonic minimization is the intricate optimization problems because the nonlinear transcendental equations have multiple local optima. Increasing the degrees of freedom in the suggested method means that the number of switching angles increases. The suggested method is able to eliminate high number of undesired harmonics. As the number of switching angles increases, using either traditional iterative techniques or resultant theory method gets useless. In this paper to overcome this problem the imperialist competitive algorithm (ICA) is used. Also a DC-DC converter is used to enhance the SHE performance in the range for which the conventional SHE methods do not have any solution. Experimental and simulation results of a 9-level inverter show that the proposed method effectively minimizes a large number of particular harmonics so the total harmonics distortion of output voltage will be lower.
