A Communication Based Model of Power

Description: We are affected greatly by power, and often do not understand what power is, how it is used, and its many other facets. Power and communication are interrelated, but how they relate to each other has been hard to understand. The model presented in this thesis explicates the relationship between the two critical variables. Power is portrayed as a hierarchical structure that is based on influence (communication) where the intensity and likelihood of success of power attempts increase as the level of power increases. The hierarchical structure has four levels, including influence at its base, and prominence, authority and control at the higher levels.

Digitally Curious: A Qualitative Case Study of Students’ Demonstrations of Curiosity in a Technology-Rich Learning Environment

Description: Curiosity is an important construct for educators as it is connected with knowledge and higher-order thinking, goal-oriented behavior, motivation, and persistence. It is also negatively correlated with boredom and anxiety. While research documents this strong connection between learning and curiosity, no studies existed exploring curiosity in a technology-rich learning environment. The purpose of this study is to identify and examine whether students demonstrate curiosity in a sixth grade mathematics classroom with technology-integrated learning and if so, how and why. Technology-rich work was designed for students and included in the study to examine students’ demonstrations of curiosity while learning mathematical procedural knowledge, conceptual knowledge and problem solving knowledge. A case study methodology was used with 13 students purposefully selected from a Title I sixth grade class to participate. Data were collected from interviews using a semi-structured interview protocol and triangulated with observations and students’ reflective writings. Interviews were transcribed and coded. A total of 60 codes and four categories were identified. Three themes emerged: 1) digital play; 2) welcome and unwelcome scaffolds; and 3) action is power; power follows ideas. These themes identified ways in which students demonstrated curiosity in the sixth grade mathematics classroom and thus can inform educators.

Power-benefit analysis of erasure encoding with redundant routing in sensor networks.

Description: One of the problems sensor networks face is adversaries corrupting nodes along the path to the base station. One way to reduce the effect of these attacks is multipath routing. This introduces some intrusion-tolerance in the network by way of redundancy but at the cost of a higher power consumption by the sensor nodes. Erasure coding can be applied to this scenario in which the base station can receive a subset of the total data sent and reconstruct the entire message packet at its end. This thesis uses two commonly used encodings and compares their performance with respect to power consumed for unencoded data in multipath routing. It is found that using encoding with multipath routing reduces the power consumption and at the same time enables the user to send reasonably large data sizes. The experiments in this thesis were performed on the Tiny OS platform with the simulations done in TOSSIM and the power measurements were taken in PowerTOSSIM. They were performed on the simple radio model and the lossy radio model provided by Tiny OS. The lossy radio model was simulated with distances of 10 feet, 15 feet and 20 feet between nodes. It was found that by using erasure encoding, double or triple the data size can be sent at the same power consumption rate as unencoded data. All the experiments were performed with the radio set at a normal transmit power, and later a high transmit power.

The Changing Role and Responsibilities of Audit Committees in the United States

Description: The corporate form that developed in the early 20th century created enormous pressure for corporate governance mechanisms to curb the power of corporate managers. Berle and Means, legal pluralists, warned about concentrating economic power in the hands of a small but powerful class of professional managers. They claimed this "new form of absolutism" required governmental oversight and viewed boards of directors as part of management, rather than monitors for shareholders. The Securities and Exchange Commission (SEC) proposed that corporations establish a special board committee, made up of "nonofficer members" in response to the McKesson & Robbins scandal of the late 1930s. My dissertation examines the evolution of the U.S. corporate audit committee through three specific time periods: (1) 1920-1954; (2) 1955-1986; and (3) 1987 to the passage of the Sarbanes-Oxley Act of 2002. My purpose is to determine if evolution of the audit committee throughout these periods has been a reform continually couched in symbolism or whether the audit committee concept has evolved into real reform, allowing proper corporate governance and mitigation of unchecked corporate power. My analysis is a traditional empirical analysis, relying on both primary and secondary sources to develop a coherent ordering of facts. I use narrative in a narrow sense as my historical methodology, examining patterns that emerge and interpreting facts to develop a clear understanding of demands for and uses of audit committees. I use a holistic approach in studying the data, using narrative to show how these patterns ensue from the historical data.

The power of teams: Do self-managing work teams influence managers' perceptions of potency?

Description: The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

Antecedents of Power in the Distribution Channel : A Transaction-cost Perspective

Description: A discussion of reward, coercive, expert, legitimate, and referent power bases was the initial focus of this research. A review of the power sources literature suggested that vertical integration within a channel of distribution was a crucial precursor to develop a structure to facilitate the use of power without creating a significant conflict among channel participants. Elements of transaction cost analysis (TCA) were offered as being suitable for determining the existing level of vertical integration among respondent firms. Accordingly, the purpose of this study was to develop a tentative model to determine proper use of power within varying levels of vertical integration.

A Constructivist Approach to the Thematic Apperception Test

Description: The purpose of this study is to explore the possibility of interpreting the Thematic Apperception Test (TAT) in constructivist terms. This research project involved a qualitative approach, focusing on abductive discovery and phenomenological critique. From constructivist theory, the core ordering processes of reality, identity, power, value, and relatedness were used to interpret a subject's TAT narratives. The author of the study chose one subject from the three with which he worked to present a case study. Chapter One of the research project reviews the literature of both TAT studies and constructivist theory. The author first discussed reliability and validity studies involving the TAT. Second, the author discussed constructivist theory, focusing on its philosophical antecedents and its theoretical framework. Chapter Two of the project establishes the methods and procedures utilized during the project. The core ordering processes as taken from constructivist theory are defined and discussed in detail. Chapter Three represents the bulk of the study, presenting the results and discussion of the results. Following a discussion of the results, the author critiqued the results, and based on the critique discussed procedural changes and implications for future research.

A Performance Analysis of the EBWR at Various Power Levels

Description: From Introduction: "This study is an attempt to predict the operating performance of EBWR (Experimental Boiling Water Reactor) at various power levels. It was done at the same time that EWBR was raised in power up to 100 MW, and so an excellent possibility was given to check the validity of the used performance analysis. Rather than giving a general and complete outline of the analysis or establishing a new approach, the study outlines and specifies the numerous practical problems involved in this analysis, and tries to explain the discrepancies between predicted and experimental results."

Gender, Power, and Language in Anglo-Saxon Poetry

Description: Many Old English poems reflect the Anglo-Saxon writers's interest in who could exercise power and how language could be used to signal a position of power or powerlessness. In previous Old English studies, the prevailing critical attitude has been to associate the exercise of power with sex—the distinction between males and females based upon biological and physiological differences—or with sex-oriented social roles or sphere of operation. Scholarship of the last twenty years has just begun to explore the connection between power and gender-coded traits, attributes which initially were tied to the heroic code and were primarily male-oriented. By the eighth and ninth centuries, the period in which most of the extant Old English poetry was probably composed, these qualities had become disassociated from biological sex but retained their gender affiliations. A re-examination of "The Dream of the Rood," "The Wanderer," "The Husband's Message," "The Wife's Lament," "Wulf and Eadwacer" and Beowulf confirms that the poets used gender-coded language to indicate which poetic characters, female as well as male, held positions of power and powerlessness. A status of power or powerlessness was signalled by the exercise of particular gendered traits that were open for assumption by men and women. Powerful individuals were depicted with masculine-coded language affiliated with honor, mastery, aggression, victory, bravery, independence, martial prowess, assertiveness, physical strength, verbal acuteness, firmness or hardness, and respect from others. Conversely, the powerless were described with non-masculine or feminine-coded language suggesting dishonor, subservience, passivity, defeat, cowardice, dependence, defenselessness, lack of volition, softness or indecisiveness, and lack of respect from others. Once attained, neither status was permanent; women and men trafficked back and forth between the two. Depending upon the circumstances, members of both sexes could experience reversals of fortunes which would necessitate moving from one category to the other, on more than one ...

Developing Policy for a Tech Program Based on Understanding Organizational Practices

Description: This thesis contributes to research that informs the studies of organizational management and organizational anthropology. It examines the internal hierarchy and organizational practices of a Tech Company and describes how findings contributed to policy recommendations aimed towards supporting a “guild” model for organizational success. The data collecting and research were undertaken while working as an employee of the Tech Program and subsequent analysis continued past the end of that phase of work. Methods included semi-structured interviews which captured the sentiments and understandings of employees within the organization, and a questionnaire which revealed sentiments and experiences from former employees. These were buttressed with participant observation engaged through a participatory action research methodology. Findings add to the work directed towards understanding the effect of Founder’s Syndrome within organizations. Additionally, this thesis contributes to a growing body of research centered on best practices for fostering positive organizational growth by creating lines of communication from front-line employees to management level employers.

The Interrelationships of Strength, Speed, Power and Anthropometric Measures in College Aged Women

Description: The purpose of the investigation was to determine the interrelationships of strength, speed, power and anthropometric measures in women. Sixty females ranging in ages from 18 to 25 volunteered as subjects. Subjects were measured for strength on the bench press, leg extension and leg curl, power vertical jump, speed--a 40 yard dash, body weight (BW) and fat weight (FW) using a scale and skinfold tests. The correlations for strength and power (.35 to .53), strength and speed (-.37 to -.56) and speed and power (-.45) were significant (p < .01). Partial correlations with (BW) and (FW) held constant were also significant, but were not significantly greater than their zero-order correlations.

The Power of the Servant Teacher

Description: An instructor's power in the classroom is constructed and sustained through communication. The aim here is to examine how a teacher's power can be negotiated through a lens of servant leadership in hopes of furthering modes in which communication scholars can train future teachers to utilize their power in the classroom. I hypothesize that a teacher utilizing a servant leadership framework employs more pro-social behavioral alteration techniques (BATs). Participants were asked to answer an online survey with questions regarding a chosen instructor's attributes of servant leadership and behavioral alteration messages (BAMs). My hypothesis was partially supported in that that are perceived to use persuasive mapping a specific dimension of servant leadership engage in significantly more pro-social BATs; however, instructors with higher levels of emotional healing engage in significantly more anti-social BATs. Additionally, the gender of the participant and rank of the instructor evaluated influenced students' perceptions of compliance-gaining strategies. The discussion examines the specific dimensions of servant leadership as they relate to power and explores future directions for research examining professional development and training for future faculty and the need to examine gender of participant and instructors with an experimental research design.
