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

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

Date: December 2005
Creator: Hass, Nicolette P.
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.

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

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

Date: August 2010
Creator: Teed, Dan Graham
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 ...

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

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

Date: December 2006
Creator: Vishwanathan, Roopa
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 ...

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

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

Date: August 2011
Creator: McLeod, Julie Kiser
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.
