Stages of Transformative Self-Authorship

This chapter focuses on the development of narrative structure. The chapter first summarizes basic principles of structural–developmental theories of self. The stages mark increasing degrees of structural complexity and coherence (i.e., value perspectivity) in one’s narrative identity. At each successive stage, the individual is better able to differentiate and integrate perspectives on the self and others. Coupled with themes of eudaimonic growth, these stages also mark the development of wisdom. The stages of self-authorship are pre-authorship, impulsive, egoist, groupish, independent, constructivist, organismic, dynamic, integrative, and post-integrative. Unlike previous stage models, this model emphasizes stages of transformative self-authorship—that is, how the idea of growth is interpreted at each stage with greater complexity and coherence. The chapter also explains how the person of each stage interprets the thinking of previous stages and more advanced stages.

God’s Gardening

Chapter 4 continues the analysis begun in chapter 3 of the Pelagian controversy, now turning attention to the specific question of how God impacts the will. It tackles this question in two parts. The first focuses on the theme of prayer. Throughout the Pelagian controversy, Augustine consistently points to prayer, especially the Lord’s Prayer, as evidence of God’s impact on the will. The Christian practice of prayer, as interpreted in scripture, is a key source for Augustine’s views about God’s impact upon the human will. The second part addresses how Augustine’s views develop over time. Whereas Augustine’s estimation of what is in human power with respect to good willing contracts over the course of the Pelagian controversy, his estimation of the extent of God’s role in effecting good human willing expands with each successive stage. Throughout the controversy, however, he views God’s aid as indispensible for right human willing.

On “Crystal Growth” in Harmonic Space

James Tenney talks about his “crystal growth” algorithm, an idea that suggests a new “harmonic syntax” for harmonic space. As a quantitative model, it is both suggestively rich for future composition and plausible as a description of the history of tonal expansion. In this algorithm, sets of points are chosen, one by one, in some n-dimensional harmonic space, under the condition that each new point must have the smallest possible sum of harmonic distances to all points already in the set. That is, at each successive stage in the growth of the harmonic lattice, the next ratio added to the set is one whose sum of harmonic distances to each ratio already in the set is minimal. In relation to this algorithm, Tenney considers the Pythagorean pentatonic scale, which may be conceived as a pitch set that arises when extension into the 3,5-plane is just slightly delayed beyond the point where the algorithm would have begun that extension.

Perolehan Tio2 Dari Iron Ore Mengandung Titanium Melalui Proses Reduksi Karbon Dan Pelarutan Asam

<span>REDUCTION AND LEACHING PROCESSES<span><strong>. </strong><span>Indonesia has a large source of iron ore <span>which is quite tempting for the purposes of exploitation in form of raw materials as well as <span>for the production of pig iron. However, not all sources of iron ore are proved useful since <span>not only because the present of deposit is scattere dinamounts of less significant but also <span>because it contains element of tin oxide compounds with iron like ilmenite or FeTiO<span>3<span>. <span>However,ilmenite can actually be used as a source of titanium metal which is much more <span>valuable than Fe it self. In order to recover the Ti from their respective compound it is <span>required the release of strong bonds between the atoms in the compound. This paper reports <span>the recovery of Ti oxide of ilmenite containing iron ore which was obtained through a <span>combination of carbon reduction and acid leaching processes. Carbon reduction of iron ore <span>was carried out through mechanical milling between iron ore and carbon with a ratio of 1:1. <span>This was successively followed by a sintering at a temperature of 1000 <span>o<span>C employing a <span>heating rate of 10 ° C/min for 0-3 hours. The reduction process has resulted in the <span>formation of 27.83wt% TiO2. In order to improve the recovery level of TiO<span>2<span>, further <span>reduction process was conducted through an HCl leaching. This successive stage produced <span>fine powders in the form of deposits. Based on our quantitative analysis, the recovery of <span>TiO<span>2 <span>increased to a level of 73.73%.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /></span></span></span></span></span></span></span></span></span></span></span>

The studies of granitoids from the Sobótka region in light of theories of the origin of colour in minerals

The article presents the results of the studies of 19 feldspar-quartz raw materials samples, coming from deposits located in the Sobótka region, in light of four distinct physical theories explaining mechanisms for creating the colour of minerals. This is a successive stage of research carried out by the author on reasons for colour variation of samples after firing at 1200°C. This step encompassed a detailed chemical analysis for main and trace elements contents of all the investigated samples as well as Mössbauer studies of two of them. The chemical analysis reveals that the darkest samples are characterised by the highest contents of the following colouring compounds and elements: Fe2O3, MnO, Th, U, Ce, Nd, and V, accompanied by a relatively low amount of TiO2. The Mössbauer studies demonstrated the quantitative predominance of Fe2+over Fe3+in the sample of a relatively darker hue with a high Fe2O3content, while its spectra parameters suggest that Fe2+is located in octahedral coordination that can result in a cold blue tint. Cations Fe3+(located probably in the tetrahedral position) prevail in the other analysed sample that contain less Fe2O3and a relatively high content of TiO2, Ce, and Nd. This probably causes a warm, reddish shade of the sample. The above-mentioned observations and examinations lead to the finding that, at this stage of the investigations, the crystal field theory could be the best suited for the interpretation of colour of the studied samples. This formalism associates the colour origin with ions of the transition elements, some REE and actinides located in the structure of minerals, and their ability to selectively absorb visible light.

Mathematical Model of Gas, Powder and Bed Flow in Metallurgical Shaft Furnaces

This paper presents the second phase of model investigations. In the first phase research into flow for the system “gas transporting powder - moving packed bed” was conducted in the physical modeling. The influence of bed, powder and gas parameters on values of interaction forces and phenomena occurring in investigated system was defined.The article discusses the successive stage of investigations into gas flow carrying the powder through the descending packed bed. The research was performed with the application of mathematical modeling after tests with a physical model in use had been accomplished. The elaborated mathematical model was used to calculate resistance values of gas flow carrying the powder through the descending packed bed, masses of ‘static’ and ‘dynamic’ powders as well as total mass of powder holdup in the bed. Then the verification of the model was done comparing the obtained results with those from the physical model.

Ukraina, Rosja i problem peryferyjności

In this essay, the author addresses the question of Ukraine’s and Russia’s relations with the West in the modern and contemporary era. He believes that the revolution in Ukraine in 2013/2014 signifies a successive stage in Ukraine’s emancipation and modernization, which began with the emergence of a separate nation on its territory in the 19th century. The author is in favor of the further use of such conceptual categories as the ‘centre’, the ‘periphery’, and ‘modernization’. He thinks they still permit the description of the real developmental distance between different parts of the world and the analysis of strategies aimed at diminishing that distance. In his opinion, Ukraine’s present chance for modernization is unambiguously connected with its choice of the ‘western’ road of development. He interprets the Russian attempt to counteract this choice by force as an expression of the disappointment experienced by the elite of the former empire. In essence, it is a sign that Russia is remaining in a peripheral situation in regard to the West, which is ‘escaping’ it.
