The Fabric of Entropy: A Discussion on the Meaning of Fractional Information

Why is the term information in English an uncountable noun, whereas in information theory it is a well-defined quantity? Since the amount of information can be quantified, what is the meaning of a fraction of that amount? This dissertation introduces a quasi-entropy matrix which developed from Claude Shannon's information measure as an analytical tool for behavioral studies. Such matrix emphasizes the role of relative characteristics of individual level data across different collections. The real challenge in the big data era is never the size of the dataset, but how data lead scientists to individuals rather than arbitrarily divided statistical groups. This proposed matrix, when combining with other statistical measures, provides a new and easy-to-do method for identifying pattern in a well-defined system because it is built on the idea that uneven probability distributions lead to decrease in system entropy. Although the matrix is not superior to classical correlation techniques, it allows an interpretation not available with traditional standard statistics. Finally, this matrix connects heterogeneous datasets because it is a frequency-based method and it works on the modes of data rather than the means of values. It also visualizes clustering in data although this type of clustering is not measured by …

Perceptions of Associates to Embrace Technology Used in Teams in the Workplace (open access)

Perceptions of Associates to Embrace Technology Used in Teams in the Workplace

This study explores employees' desire to embrace both a legacy operating system and a new workflow engine utilized in the workplace. The goal is to better understand the partnership and relationship the users build with the technologies and how that impacts usage behavior. The research is centered on a mixed-method case study using survey and episodic interview techniques of data collection. Models and methodologies providing the foundation for this study include Venkatesh and Davis's technology acceptance model 2 (TAM 2) and Venkatesh, Morris, Davis, and Davis' unified theory of acceptance and use of technology (UTAUT) model, coupled loosely with concepts from Brooks and Atkinson's StructurANTion Theory. A new, adapted model is created to capture and understand the anthropomorphic characteristics users apply to the technology. This study yields important information for the future theoretical frameworks as elements such as trust and control, and descriptive variables like age and tenure have not factored into existing theoretical frameworks and models. Users can often anthropomorphize technology, viewing it as part of the social team to help improve their work. Through this lens, users expect information systems to be controllable and trustworthy to respond to their needs both alone and within the function of the …

An Analysis of Student Perceptions of Teaching Effectiveness for Instructors Who Teach the Same Course in the Same Semester in Both Online and Face-to-Face Formats (open access)

An Analysis of Student Perceptions of Teaching Effectiveness for Instructors Who Teach the Same Course in the Same Semester in Both Online and Face-to-Face Formats

There is an increasingly number of students taking online classes in lieu of or in addition to the traditional face-to-face format. With this trend, there are questions that naturally come to the surface. The biggest question being "is teaching in the online arena just as effective as the face-to-face arena?" This dissertation aims to pursue that line of questioning by analyzing students' perceptions of the teaching effectiveness for instructors who teach the same course in both an online and face-to-face format in the same semester. The data are analyzed through the lens of the social capital theory. Social capital has never been applied to the classroom before as its focus has traditionally been on community development. However, social capital theory addresses interpersonal relationships and their impact on knowledge sharing behavior. This theory identifies three dimensions, which appear to have a parallel track with the student evaluation components; each is analyzed against each other. These dimensions include structured, cognitive and relational and are compared to the components of the student evaluation tool, which includes organization and explanation of materials, learning environment and self-regulated learning.
