Aesthetic Experience
This thesis presents an outline of a theory of aesthetic perception based on the study of the writings of leading aestheticians today. It combines some aspects of formalist, associationalist and emotionalist theories. The formalist idea that form in the most significant aspect of a work of art is used in discussion of the artist’s creation. Artistic form is the result of the artist’s creation of relationships among the formal elements. Artistic form is known to be expressive owing to its association with past visual perception of the relationship among the formal elements in everyday experience. The viewer’s attitude in looking at a work of art is presented as a contemplative attitude. It is characterized by self-privation and a subconscious activity of association. The emotionalist idea that an emotion is the prime end of an aesthetic experience is upheld in this thesis. The integration of formal and emotional associations causes a disturbance which becomes conscious as an emotion that is called aesthetic.
A discussion of paintings by Mark Rothko is used to elucidate how the theory of aesthetic perception is applicable to an artist’s work. Statements made by the artist are used to confirm the ideas presented in the theory.</p
Identifying Stakeholders’ Needs for Agricultural Communications in Higher Education Curriculum in Australia
Agriculture is a vital part of the Australian economy. With an industry poised for growth, and a growing disconnect between consumers and agriculture, additional communication efforts are needed. The purpose of this study was to complete a curriculum visioning process to inform agricultural communications curriculum development in Australia. This study used a qualitative research design consisting of face-to-face, semi-structured interviews with individuals from 14 agricultural organizations and two universities. The results indicated the industry is addressing many challenges, but also has opportunities that would benefit from strategic communication efforts. Participants provided suggestions regarding the specific communication skills and agriculture knowledge future employees should possess. Recognizing these competencies informed the curriculum visioning process for agricultural communications as an academic discipline within Australian higher education. Recommendations for both practice and future research are provided
Effects of an innovative recruitment workshop on selected Texas urban high school students' knowledge and perceptions of agriculture
The Big City, Big Country Road Show (BC2BC) is a 2.5-year project designed to
recruit non-traditional populations, urban and minorities, into post-secondary
agricultural science degree programs. Through experiential learning, BC2BC introduces
students to various agricultural communications skill sets in an effort to broaden
students’ views of opportunities in agriculture. This study attempted to measure Texas
urban high school students’ perceptions of agriculture as a subject, a college major, and
a career, before and after participation in the BC2BC program in summer of 2007. The
study also looked at students’ perceptions of careers attainable with an agricultural
degree and students’ general agricultural knowledge levels, self-reported and tested.
Pre–and post–test mean comparisons revealed positive increases in student perceptions
of agriculture and an increase in self-reported agricultural knowledge levels after
workshop participation. The results of this study have implications for year two BC2BC
workshops and may serve as a potential model for recruitment programs of
underrepresented populations into colleges of agriculture
Crisis theory related to divorce and remarriage
This research challenges the belief that a specific event is a crisis. The major purpose was to determine whether unusually high levels of stress precede the decision to divorce or to remarry. The divorced were tested for the 12 months prior to the decision to divorce; the remarried were tested for the 12 months prior to the decision to remarry; and the currently married to their first spouse were tested for the 12 months prior to participation in the study. A second major purpose was to test two major assumptions in crisis theory: (a) What is a crisis for one person will not be a crisis for another, and (b) after a crisis, an individual may approach, but not exceed, the level of organization at which one was functioning before the crisis occurred. The purposive sample consisted of 90 subjects. Sixty had experienced divorce and 30 were still married to their first spouse. Twenty of the 60 divorced subjects were remarried and tested as such. The Life Events Inventory (L.E.I.) by Cochrane and Robertson (1973) was the instrument used to determine amounts of accumulated stress during designated 12-month periods. The instrument has a reliability factor of 0.89
ОСОБЛИВОСТІ ПОБУДОВИ ТА ОСНОВІ НАПРЯМКИ РОЗВИТКУ ВІРТУАЛЬНИХ ЦИФРОВИХ АСИСТЕНТІВ
The article analyzes the main aspects of creating virtual assistants that are part of intelligent computer programs – artificial intelligence systems (AI). The main task of “artificial intelligence” is to ensure effective communication of intelligent robotic systems (including unmanned vehicles) with humans. The basis of the above is in-depth training (systematic machine translation, speech recognition, processing of complex texts in natural languages, computer vision, automation of driving, etc.). This machine learning subsystem can be characterized using neural network models that mimic the brain. Any neural network model learns from large data sets, so it acquires some “skills”, but how it uses them remains for engineers, which ultimately becomes one of the most important problems for many deep learning applications. The reason is that such a model is formal and without an understanding of the logic of its actions. This raises the question: is it possible to increase the level of trust in such systems based on machine learning? Machine learning algorithms are complex mathematical descriptions and procedures and have a growing impact on people's lives. As the decision is increasingly determined by the algorithms, they become less transparent and understandable. Based on the foregoing, the paper considers the issues of the technological component and the algorithms of virtual digital assistants, conducts information modeling based on the conceptual model of the interaction of the virtual assistant with the database, and analyzes the scope and further development of the IT-sphere.В статті проаналізовані основні аспекти створення віртуальних асистентів, що входять до складу інтелектуальних комп’ютерних програм – системи штучного інтелекту (ШІ). Основним завданням «штучного інтелекту» є забезпечення ефективної комунікації інтелектуальних робото-технічних систем (в том числі і безпілотні транспортні засоби) з людиною. Основою вищезазначеного виступає глибинне навчання (систематизований машинний переклад, розпізнавання мови, обробка складних текстів на природних мовах, комп'ютерний зір, автоматизація керування автомобілем та ін.). Складну систему машинного навчання можна охарактеризувати застосуванням моделей нейронних мереж, що імітують роботу інтелектуальних здібностей людини. Будь-яка модель нейронної мережі навчається та формує свій досвід на опрацюванні великих наборів даних, таким чином, вона набуває деяких «навичок», але, яким чином вона їх використовує – для інженерів й досі залишається це гострим питанням, що стає однією з найважливіших проблем для багатьох додатків глибинного навчання. Головна причина полягає в тому, що така модель є формальною та без розуміння логіки власних дій, що виконуються нею. Тут постає питання: чи можливо підвищити рівень довіри до таких систем, що побудовані на основі машинного навчання? Алгоритми машинного навчання представляють собою складні математичні описи і процедури та надають зростаючий вплив на життя людей. Оскільки рішення все більше визначаються алгоритмами, вони стають менш прозорими і зрозумілими. Виходячи з вище вказаного, в роботі розглянуто питання технологічної складової та процеси алгоритмізації віртуальних цифрових асистентів, проведено інформаційне моделювання на основі концептуальної моделі взаємодії віртуального асистента з базою даних та проаналізовані сфери застосування та подальшого розвитку ІТ-сфери

Service-Learning and Leadership Life Skills: An Experimental Study
This study examined the effect of service activities on the development of leadership life skills in youth and (queried) if having a reflection component as part of the activity makes a difference. Additionally, the study examined the impact of selected demographics including age, gender, type of service completed monthly and 4-H membership on the development of leadership life skills. Participants in the study were from two samples. One group represented the El Paso National Youth Service Day, the other represented the District 11 4-H Leadership Lab in Branham, Texas. Participants were randomly assigned to a control (no reflection) or treatment (with reflection) group. Youth participants self rated their leadership life skills using a 33-question post-test only questionnaire. Demographics were reported in nine additional questions. The major findings of the study are as follows: 1) Overall, the participants reported their perceived leadership life skills to be high in four of the five subscales; 2) The inclusion of a reflection component did not significantly affect perceived leadership life skills; 3) Type of service, whether direct or indirect, had a significant impact on perceived leadership life skills; 4) 4-H membership had a significant impact on the Personal Leadership Development subscale
