Louisville-Jefferson County police consolidation : officers\u27 perception of organizational justice.

This study focuses on how the 2001 consolidation of the Louisville Division of Police (LPD) and Jefferson County Police Department (JCPD) impacted police officers\u27 perception of fairness of the process. To accomplish this, the study asked four research questions: 1) How do police officers view a just department?, 2) How do police officers\u27 justice judgments affect their reaction to the organization and supervisors?, 3) How do police officers form overall perceptions of fairness?, and 4) How do LPD and JCPD officers differ in their perceptions of fairness of the consolidation? A systematic random sample with replacement was used to invite police officers from the newly established Louisville Metro Police Department (LMPD) to participate in this study. Officers were selected based upon their former agency (i.e., LPD or JCPD) and their rank (i.e., patrol officer or supervisor-including the ranks of sergeants and above). Forty police officers from a population of903 former LPD and JCPD members, still on LMPD at the time of this study, agreed to participate. Police officers hired post-consolidation (295 officers) were not included in the population for this study. The findings in this study indicate that: 1) police view a just or fair department based upon justice rules (i.e., equality, accountability, and flexibility/discretion) and interpersonal (i.e., comparisons made between officers on the same department) and interdepartmental comparisons (i.e., comparisons made between departments); 2) justice judgments can result in negative reactions directed toward the administration, but that an officer\u27s sense of professionalism or lack of control of the situation could influence how he/she reacts; 3) police officers form overall perceptions based upon a value assessment of justice component and justice source; and 4) LPD and JCPD officers differed on their perceptions of fairness, based in part upon the issue of parity (i.e., pay and benefits)

No Independence without Sovereignty! The Resistance of Emperor Ḫaylä Śǝllase I to the British Occupation of Ethiopia (1941–1944)

This article examines how Emperor Ḫaylä Śǝllase I succeeded in removing the British military occupation of Ethiopia during World War II with only a minimum of bloodshed. It outlines the various strategies and tactics the Emperor of Ethiopia employed to regain control over his empire. The text also asserts that he engaged in a pre-Cold War variant of the policy of flexible response which permitted him to resist British military rule without provoking a violent response from his occupier. The text highlights a handful of the numerous tactics and strategies which were employed by indigenous leaders and their allies not only in Africa but also throughout the developing world to successfully resist European colonial rule during and after World War II

Sustainability Proposal: Water

Water Sustainability at Sarah Lawrence College: Abstract Excessive water use and poor water management has done great harm to the environment through the introduction of pollutants into freshwater supplies, as well as, increase the risk of extreme weather phenomena such as droughts and storms. To help lessen the environmental footprint of Sarah Lawrence College, we researched a number of strategies to reduce water usage across the campus. Technologies such as dual-flush toilets and low-flow showerheads would not only save the school money, but drastically reduce the amount of water used by across the board. The implementation of rainwater collection systems to provide an additional source for plumbing and landscaping was also discussed. For costs and figures, some comparative studies looked at other institutions with similar plans around the country.https://digitalcommons.slc.edu/undergrad_sustainproject/1008/thumbnail.jp

Characterization of Damping Properties in 3D Printed Structures

Current research on the effectiveness of a subordinate oscillator array (SOA) as a broadband mechanical filter relies on adequate knowledge of the SOAs material properties. Recent studies have shown a high sensitivity of these structures to disorder. A desire to produce large numbers of arrays to test this sensitivity to disorder motivated a transition from metal to 3-dimensional printed plastic SOAs. Irregularities associated with the curing process of the 3D printed polymers, as well as a general inconsistency of material properties of plastics, in turn highlighted the need for characterization of properties of 3D printed materials, especially those properties related to damping. As part of this study, several 3D printed plastic cantilevers, varying in material, printing technique, and printing orientation, are measured. Quantities of interest include the Young’s modulus and density, as well as phenomenological properties, like the quality factor of specific designs. An ASTM standard test method for property determination is implemented with a laser Doppler vibrometer (LDV) to test each polymer. In addition to the ASTM protocol, tests are conducted in vacuum to distinguish internal damping mechanisms of the cantilever from external fluid mechanisms. Results are compared to both analytic and numeric predictions and published theory

Feasibility Analysis of Two Indirect Heat Pump Assisted Solar Domestic Hot Water Systems

This thesis is an analysis of the simulated performance of two indirect heat pump assisted solar domestic hot water (i-HPASDHW) systems compared to two base systems: an electric domestic hot water (DHW) system and a traditional solar domestic hot water (SDHW) system. In this study, the four systems of interest were modeled in the TRNSYS software and simulated for a year in order to compare their performances. All of the systems had the same load profile and aimed to deliver domestic hot water at a constant temperature. This insured that each system delivered approximately the same amount of energy for the simulated period, thereby creating a common basis for comparison. The heat pump was introduced into the system configuration in an attempt to further improve the performance. Theoretically, the heat pump should send colder fluid to the collector which will extend the solar collection periods, both daily and seasonally when compared to the traditional SDHW system, as well as increase the efficiency of the collector. This will help to reduce the reliance on the electric auxiliary heaters and thus decrease the total electricity consumption. Both i-HPASDHW systems considered for this thesis collected more solar energy over the course of the simulated year compared to the base traditional SDHW system. They also consumed less electricity than the two base systems, which directly correlated to lower annual operating costs. It was concluded that the two i-HPASDHW systems analyzed in this study proved to be feasible configurations that performed more efficiently than the two base systems under the simulation conditions. However, it is important to understand that the results presented apply to the specific configurations. While the potential has been shown, prototypes must be built and tested with properly sized equipment for specific applications to get an accurate idea of the potential benefits. Also, equipment costs must be considered to determine payback periods for each system

Effect of Increased Damping in Subordinate Oscillator Arrays

Previous literature has shown that large structures with a significant number of smaller attached structures exhibit much higher apparent damping than was predicted by models. Further research into this effect led to the discovery that arrays of such small attachments can be designed to alter the response of the overall system. That work also showed that small variation in the distribution of attachment mass or stiffness degrade the performance of the system. Additive manufacturing has now matured such that several methods provide the capability to realize the tolerances required to effectively test these designs. This paper discusses the use of StereoLithography Apparatus (SLA) optical fabrication to test the error sensitivity of different materials using laser vibrometry to characterize the mechanical behavior of the system
