Love Of All Loves: Politics And Fraternity In The Charismatic Vision Of Chiara Lubich, Antonio Maria Baggio

Claritas: Journal of Dialogue and Culture

Chiara Lubich gave a fundamental contribution to the rediscovery of fraternity, particularly during the last years of her public engagement. The present article tries to understand the original meaning that Chiara gave to fraternity. Her interpretation is rooted within the Trinitarian reality and, particularly, in Jesus forsaken; fraternity is deeply linked with the mystical experience of ’49. There is a “logic” of fraternity, that rises from the Trinitarian “logic.” As a matter of fact, on one side we may fully understand her conception of fraternity only in the religious background of the Christian faith. On the other side, Chiara’s thought …

Flight Energy Management Training: Promoting Safety And Efficiency, Juan R. Merkt

Journal of Aviation Technology and Engineering

Poor aircraft energy management can lead to unsafe and inefficient operations. Despite their impact on safety and economy, energy management skills are not adequately taught or evaluated in civilian pilot training. This paper 1) addresses the need for better energy management training, 2) provides a conceptual and pedagogical framework for later curriculum development, and 3) suggests key attributes of an effective training program. To make the case, the study uses energy management to link safety and efficiency. It then synthesizes energy principles across disciplines and illustrates how such principles, once simplified, become powerful instructional tools. Finally, it suggests that an …

On server side, social media data analysis algorithms can be implemented and published in the form of web services. Visual Interface can then be implemented in the form of thin clients that call these web services for …

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu

The Summer Undergraduate Research Fellowship (SURF) Symposium

Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …

Mchugh, Steven J. Foster, Elizabeth R. De Waard, Michael Streit, Richard B. Antoniolli, Ernest W. Knight, David S. York, Jacob Luedtke

Journal of Aviation Technology and Engineering

Since 2005, reported laser attacks from people on the ground directed towards arriving and departing aircraft have increased over 300%. A laser aimed at the windshield of an aircraft startles a pilot and may cause injury. This study determined empirical evidence of laser intensity in the flight deck and the potential for harm to the human eye at various distances. Results of this study revealed that relatively low-powered lasers had measured intensity levels through cockpit windshields at the 200 and 500 feet distances that may cause damage to crewmembers’ eyes according to standards established by the federal government. At longer …

Estimation Of Variation For High-Throughput Molecular Biological Experiments With Small Sample Size, Danni Yu

Open Access Dissertations

Motivation: In the quantification of molecular components, a large variation can affect and even potentially mislead the biological conclusions. Meanwhile, the high-throughput experiments often involve a small number of samples due to the limitation of cost and time. In such cases, the stochastic information may dominate the outcome of an experiment because there may not be enough samples to present the true biological information. It is challenging to distinguish the changes in phenotype from the stochastic variation.

Methods: Since the biological molecules have been quantified with different technologies, different statistical methods are required. Focusing on three types of important high-throughput …

High-Power Microwave/ Radio-Frequency Components, Circuits, And Subsystems For Next-Generation Wireless Radio Front-Ends, Kenle Chen

Open Access Dissertations

As the wireless communication systems evolve toward the future generation, intelligence will be the main signature/trend, well known as the concepts of cognitive and software-defined radios which offer ultimate data transmission speed, spectrum access, and user capacity. During this evolution, the human society may experience another round of `information revolution'. However, one of the major bottlenecks of this promotion lies in hardware realization, since all the aforementioned intelligent systems are required to cover a broad frequency range to support multiple communication bands and dissimilar standards. As the essential part of the hardware, power amplifiers (PAs) capable of operating over a …

An Eriksonian Approach To Consumer Identity, Sandra Rathod

Open Access Dissertations

Rathod, Sandra R. Ph.D., Purdue University, December 2013. An Eriksonian Approach to Consumer Identity. Major Professor: Richard A. Feinberg.

Ego development is the fifth stage in Erikson's Lifecycle Development theory (1959) and is a major psychosocial stage beginning in adolescence and lasting into emerging adulthood. Past research based upon Marcia's Ego Identity Status Paradigm (1996) has investigated a number of ideological and interpersonal domains relevant to one's ego identity, however in today's consumer societies, where what you have is at least as important is who you are or what you do, an Eriksonian approach to consumer ego identity (CEI) has …

The Role Of Soil Microorganisms In The Resistance Of Giant Ragweed, Horseweed, And Common Lambsquarters To Glyphosate, Jessica Renee Schafer-Bugg

Open Access Dissertations

Continuous glyphosate use has contributed to an increasing number of problematic glyphosate-resistant (GR) weeds. The mechanism of resistance in many GR weeds is poorly understood, in part, due to a poor understanding of how exactly glyphosate kills a plant. In previous research, the efficacy of glyphosate was demonstrated to be strongly influenced by root invading soil-borne microorganisms. However, this interaction among plants, glyphosate, and soil microorganisms has only been studied in a number of crop plants, but not in weed species. This is surprising since the soil biotic environment has a strong impact on the activity of this important herbicide. …

Development And Validation Of Pre-Service Teachers' Personal Epistemologies Of Teaching Scale (Pt-Pets), Ji Hyun Yu

Open Access Dissertations

The Internet has changed not only how we conceptualize knowledge, but also how we learn in classroom. Knowledge is not any longer transmitted from experts to non-experts, but is constructed through communication, collaboration, and integration among a network of people. In this context, teachers are expected to facilitate student-centered learning by helping students to construct knowledge through higher-order thinking rather than reproduce a series of facts. Although a growing body of research suggests that teachers' beliefs about the nature of knowledge and the process of knowing, that is personal epistemology, are related to their teaching and their students' learning, little …

Genetic Engineering Of Black Cherry (Prunus Serotina) For Reproductive Sterility And Insect Pest Resistance, Ying Wang

Open Access Dissertations

Black cherry (Prunus serotina Ehrh.) is one of the most valuable hardwoods for high- end cabinetry, furniture, architectural millwork, paneling, and veneer. However, the damage caused by cambial-mining insect pests triggers gummosis in black cherry, a non-specific defense response in which resinous gum is deposited at the site of injury. The gum defects dramatically decrease the yield of high-quality black cherry lumber, and the value can be reduced by as much as 90%. The goal of this project was to optimize the transformation and in vitro rooting system, and to develop transgenic black cherry for reproductive sterility and insect pest …

Fabricating Complex-Shaped Components By Room-Temperature Injection Molding Of Aqueous Ceramic Suspension Gels, Valerie Lynn Wiesner

Open Access Dissertations

Water-based ceramic suspension gels (CeraSGels) effectively produced dense, near-net shape ceramic parts by room-temperature injection molding, a novel processing method based on traditional ceramic injection molding. This alternative method eliminated the need for heating and cooling feedstocks to process, as is required in conventional injection molding, through control of the rheological response of the CeraSGels by simply varying polymer content without the use of any harsh crosslinking or curing agents or further chemical processes. The development of room-temperature injection molding initially focused on forming CeraSGels based on alumina, a readily available model material, in order to optimize suspension preparation and …

The methods used include chemical cross-linking, FRET, and SEC-MALS. In addition, various transport properties of CAXCK31, including …

Silica Colloidal Crystals As Emerging Materials For The High-Throughput Sizing Of Proteins By Packed Capillary Electrophoresis, Nadine K. Njoya

Open Access Dissertations

Protein heterogeneity is currently one of the leading problems in formulation of therapeutic proteins. The effectiveness of therapeutic proteins is diminished when they exhibit heterogeneity due to aggregates and degradation by-products. Furthermore, guidelines set forth by the FDA require therapeutic proteins to have high stability as well as high purity. With development time on the order of years and costs incurred in the millions, pharmaceutical companies are investing more time in finding fast and efficient ways to screen for protein heterogeneity. Current methods such as native polyacrylamide gel electrophoresis (PAGE), size-exclusion chromatography (SEC) and capillary electrophoresis (CE) are time consuming, …

Invasive Silver Carp (Hypophthalmichthys Molitrix) Protein Hydrolysates- A Potential Source Of Natural Antioxidant, Sravanthi Priya Malaypally

Open Access Dissertations

Invasive silver carp (Hypophthalmichthys molitrix), continue to spread over the Mississippi River causing a great concern for the river ecosystem due to their impact on native fish species. To minimize the negative effects of silver carp, many strategies were implemented including using it for animal feed, as fertilizers or simply discarding them into waste. However, these fish are high in protein content, making them excellent starting material for protein-derived by-products. One alternative is to recover and modify the protein in the fish into bioactive food ingredient. In the functional/ nutraceutical food industry, there is high demand for antioxidant agents. In …
