Class Size and Nursing Students\u27 Perception of Empowerment

Due to increases in enrollment and budget cuts in many states, college class sizes are reaching unprecedented sizes (Carpenter, 2006). Nursing schools are facing the same challenges. Only limited research has been conducted on the effects of class size on nursing students\u27 perception of empowerment Conger (1989) defines empowerment as the act of reinforcing one\u27s belief in his or her perception of competence. Empowerment is important for nursing students\u27 education (Chally, 1992). To achieve the optimal learning experience in face of increasing class size, it is important to explore how nursing students experience learning in both small and large class environments. This study surveyed 71 BSN students enrolled in both small- and large-size classes on their perceptions of empowerment The study\u27s findings showed statistically significant differences in favor of smail classes positively impacting the students\u27 perceptions of empowerment and the quality of their individual learning experiences

Color, composition, and thermal environment of Kuiper Belt object (486958) Arrokoth

The outer Solar System object (486958) Arrokoth (provisional designation 2014 MU₆₉) has been largely undisturbed since its formation. We study its surface composition using data collected by the New Horizons spacecraft. Methanol ice is present along with organic material, which may have formed through irradiation of simple molecules. H₂O ice is not detected. This composition indicates hydrogenation of CO-rich ice and/or energetic processing of CH₄+H₂O ices in the cold, outer edge of the early Solar System. There are only small regional variations in color and spectra across the surface, suggesting Arrokoth formed from a homogeneous or well-mixed reservoir of solids. Microwave thermal emission from the winter night side is consistent with a mean brightness temperature of 29 ± 5 K

Design of an automobile turbocharger gas turbine engine

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2003.Includes bibliographical references (leaf 24).The turbocharger gas turbine engine was designed with the intent of being built as a demonstration for the Massachusetts Institute of Technology Department of Mechanical Engineering courses 2.005 and 2.006 to supplement material covered. A gas turbine operates on an open version of the Brayton cycle and consists of a compressor, a combustion chamber and a turbine. An automobile turbocharger was chosen because it contains a compressor and turbine on a common shaft. Designs for the combustion chamber, oil system, fuel system, and ignition system were created based on research of similar projects. Many of the necessary parts were also specified.by Keane T.

An algorithm to identify automorphisms which arise from self-induced interval exchange transformations

We give an algorithm to determine if the dynamical system generated by a positive automorphism of the free group can also be generated by a self-induced interval exchange transformation. The algorithm effectively yields the interval exchange transformation in case of success.Comment: 26 pages, 8 figures. v2: the article has been reorganized to make for a more linear read. A few paragraphs have been added for clarit

Ages of the Pliocene-Pleistocene Alexandra and Ngatutura Volcanics, western North Island, New Zealand, and some geological implications

The Alexandra and Ngatutura Volcanics are the two southernmost of the Pliocene-Quaternary volcanic fields of western and northern North Island, New Zealand, northwest of Taupo Volcanic Zone TVZ. The Ngatutura Basalts are an alkalic basaltic field comprising monogenetic volcanoes. The Alexandra Volcanics consist of three basaltic magma series: an alkalic (Okete Volcanics), calcalkalic (Karioi, Pirongia, Kakepuku, and Te Kawa Volcanics), and a minor potassic series. Twenty new K-Arages are presented for the Alexandra Volcanics and 9 new ages for the Ngatutura Basalts. Ages of the Alexandra Volcanics range from 2.74 to 1 .60 Ma, and the ages of all three magma series overlap. Ages of the Ngatutura Basalts range from 1 .83 to 1.54 Ma. Each basaltic field has a restricted time range and there is a progressive younging in age of the basaltic fields of western North Island from the Alexandra Volcanics in the south, to Ngatutura, to South Auckland, and then to the Auckland field in the north. Neither of the Alexandra nor Ngatutura Volcanics shows any younging direction of their volcanic centres or any age pattern within their fields, and there is no systematic variation in age with rock composition. Any correlation of age with degree of erosion of volcanic cones is invalid for these basaltic fields; instead, the degree of erosion may be controlled by the lithology of the cones and possibly by the extent of preservation offered by the thick cover deposits of the Kauroa, Hamilton, and younger tephra beds. Stratigraphic relations have enabled the earliest member of the Kauroa Ash Formation to be dated at 2.3 Ma. This formation represents a series of widespread rhyolitic plinian and ignimbrite eruptions probably derived from TVZ and initiated during the Late Pliocene

Leksička dekompozicija i razumijevanje glagola kretanja u talijanskom i engleskom jeziku

In this paper, we combine linguistic analyses based on Event Templates (Rappaport Hovav and Levin 1998a) and psychological proposals on the complexity of verb meanings to develop an analysis of the proposed complexity differences in motion verbs in English (as a satellite–framed language) and Italian (as a verb–framed language). The key prediction from this analysis is that for both languages manner–of–motion verbs take longer to be processed than path–motion verbs: that is to say, independently of the language specific lexicalization patterns, the more complex the structure, the longer the time to process it. We also outline some recent findings that have a bearing on this prediction.U ovome radu lingvistička analiza se temelji na predlošcima događaja (Event Templates, prema Rappaport, Hovav i Levin 1998a) i psihološkim pretpostavkama o složenosti glagolskih značenja. Autori kombiniraju navedene pristupe kako bi razvili analizu predloženih složenih razlika među glagolima kretanja u engleskome (satellite-framed language, odnosno S-jezicima) i talijanskome (verb-framed language, odnosno V-jezicima). Ključna je pretpostavka ove analize da se u oba jezika glagoli koji opisuju način kretanja sporije procesiraju od onih glagola koji opisuju put i kretanje. Neovisno o jezično specifičnim obrascima leksikalizacije, što je struktura složenija to je više vremena potrebno da je se procesuira. Ovaj rad istaknuo je i rezultate recentnih istraživanja koja su bitna za navedenu ključnu pretpostavku u ovome radu
