Political Skill, Megan Paul

Umbrella Summaries

What is political skill?

Political skill refers to “the ability to effectively understand others at work, and to use such knowledge to influence others to act in ways that enhance one’s personal and/or organizational objectives” (Ahearn et al., 2004, p. 311). Unlike organizational politics, which involve selfserving and detrimental behavior, political skill involves positive, sincere, and effective influence (Ferris et al., 2005). The primary measure of political skill is the 18-item Political Skill Inventory, which assesses political skill through four factors: social astuteness, interpersonal influence, networking ability, and apparent sincerity. Example items from each factor, respectively, include “I always seem …

Department of Agronomy and Horticulture: Faculty Publications

There is growing global interest in the potential for soil reflectance spectroscopy to fill an urgent need for more data on soil properties for improved decision-making on soil security at local to global scales. This is driven by the capability of soil spectroscopy to estimate a wide range of soil properties from a rapid, inexpensive, and highly reproducible measurement using only light. However, several obstacles are preventing wider adoption of soil spectroscopy. The biggest obstacles are the large variation in the soil analytical methods and operating procedures used in different laboratories, poor reproducibility of analyses within and amongst laboratories and …

Stepping-Stones And Mediators Of Pandemic Expansion: A Context For Humans As Ecological Super-Spreaders, Eric P. Hoberg, Walter A. Boeger, Daniel R. Brooks, Valeria Trivellone, Salvatore J. Agosta

MANTER: Journal of Parasite Biodiversity

Humans represent ecological super-spreaders in the dissemination and introduction of pathogens. These processes, consistent with the dynamics of the Stockholm paradigm, are exemplified in the origin and globalized distributions of SARS-CoV-2 since initial recognition in central Asia during 2019 and 2020. SARS-like viruses are not widespread in mammals but appear widespread in chiropterans. Bats are isolated ecologically from most other assemblages of mammals in terrestrial systems. Humans may be the stepping-stone hosts for broad global dissemination and wider infection (given the opportunity) among diverse assemblages of mammals in which host and viral capacity are compatible. Human globalization mediated insertion in …

The Public’S Preferences In Supreme Court Rationale, William Svob

Honors Program: Senior Projects (Public)

Public approval of the Supreme Court has been decreasing in recent years. Given the literature’s consensus that Supreme Court rulings coincide with popular opinion more often than not, the decrease in popularity cannot be explained away by assuming the justices have made a series of widely despised rulings. This raises questions about what exactly the public wants the Supreme Court to do. There is an abundance of research covering the many factors that influence a justice to rule in a particular manner, but there is little written about what the average American believes should influence the Court. This study is …

Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy

Honors Program: Senior Projects (Public)

The production of livestock is composed of a variety of factors all effecting the outcome. For grazing livestock, a key factor in production is the grazing management system. Two of the most common grazing management systems are continuous grazing and rotational grazing. There has been evidence found proving benefits of rotational grazing in regard to vegetation productivity, and prevention and restoration of degraded rangeland. However, there is a lack of clear evidence on the relationship between grazing system and production metrics of livestock. Understanding this relationship can provide the necessary information for livestock producers in order to increase their production …

The Combined And Unique Roles Of Ptsd And Polyvictimization In Predicting Delinquency Among Adolescents, Joana Reyes

Honors Program: Senior Projects (Public)

As a supplement to previous research understanding the relationship of polyvictimization to delinquent behaviors, these analyze question the mediating role of PTSS between the two factors. A cascade model was used to understand the factors relationship, in which they influence each other independently and as a group. Therefore, it has been found that polyvictimization leads to an increase in the likelihood of delinquent behavior, PTSS was also expected to play a role in this cascade model. Analyzes found that PTSS does influence delinquency, yet not in each Wave of data.
