This volume presents the state of research across Europe to illustrate how comparable interpretative frameworks are used by archaeologists working with both prehistoric and historical societies

TOXIC LEADERSHIP AND ITS IMPACT ON FOLLOWERS AND THE COMMAND AT THE UNITED STATES NAVAL ACADEMY

The purpose of this thesis is to determine if the toxic leadership model proposed by Padilla, Hogan, and Kaiser in 2007 is supported by data collected at the United States Naval Academy in 2018. Specifically, that when a subordinate ranks their leadership low due to toxic leader traits, they will have lower organizational commitment indicating a more conducive environment, and trust for their peers will be lower indicating that there are susceptible followers who are either conforming to the toxic leadership or colluding with the toxic leadership. The analysis of the data showed that there was a moderate correlation between the existence of a toxic leader and a conducive environment, even after accounting for susceptible followers. This correlation supports part of Padilla, Hogan, and Kaiser’s 2007 toxic leadership model, that when a toxic leader exists there also exists a conducive environment, specifically that subordinates identify less strongly with the institution. No correlation was found between susceptible follower and toxic leader or susceptible follower and conducive environment. Further study is recommended on this topic to clarify whether a conducive environment allows a toxic leader to manifest, or if a toxic leader contributes to and creates a conducive environment.Lieutenant, United States NavyLieutenant, United States NavyApproved for public release.

The binary companion mass ratio distribution: an imprint of the star formation process?

We explore the effects of dynamical evolution in dense clusters on the companion mass ratio distribution (CMRD) of binary stars. Binary systems are destroyed by interactions with other stars in the cluster, lowering the total binary fraction and significantly altering the initial semi-major axis distribution. However, the shape of the CMRD is unaffected by dynamics; an equal number of systems with high mass ratios are destroyed compared to systems with low mass ratios. We might expect a weak dependence of the survivability of a binary on its mass ratio because its binding energy is proportional to both the primary and secondary mass components of the system. However, binaries are broken up by interactions in which the perturbing star has a significantly higher energy (by a factor of >10, depending on the particular binary properties) than the binding energy of the binary, or through multiple interactions in the cluster. We therefore suggest that the shape of the observed binary CMRD is an outcome of the star formation process, and should be measured in preference to the distributions of orbital parameters, such as the semi-major axis distribution.Comment: 8 pages, 4 figures, accepted for publication in MNRA
