Exploring supportive and defensive communication behavior and psychological safety between supervisors and their subordinates

Master's Project (M.A.) University of Alaska Fairbanks, 2015This project explores the relationship between supportive and defensive communication behavior and psychological safety in the organizational setting. A paper and pencil survey measuring team psychological safety and supportive and defensive communication behaviors was administered to participants in the northwestern region of the United States. Supervisor use of supportive communication behavior was hypothesized to be positively correlated with employee psychological safety. Support was found for the hypothesis. This research sought to expand the scope of our understanding of psychological safety in an organizational setting while highlighting the benefits of using supportive communication behavior

Learning from Logged Implicit Exploration Data

We provide a sound and consistent foundation for the use of \emph{nonrandom} exploration data in "contextual bandit" or "partially labeled" settings where only the value of a chosen action is learned. The primary challenge in a variety of settings is that the exploration policy, in which "offline" data is logged, is not explicitly known. Prior solutions here require either control of the actions during the learning process, recorded random exploration, or actions chosen obliviously in a repeated manner. The techniques reported here lift these restrictions, allowing the learning of a policy for choosing actions given features from historical data where no randomization occurred or was logged. We empirically verify our solution on two reasonably sized sets of real-world data obtained from Yahoo!

Die überörtliche Biotopverbundplanung als Rahmenplan bei der Aufstellung des Landschaftsplanes am Beispiel der Gemeinde Elsteraue (Burgenlandkreis)

Aufgabe der Landschaftsplanung ist es, konzeptionell und umsetzungsorientiert Erfordernisse und Maßnahmen für eine langfristige und umfassende Erhaltung, Wiederherstellung und Entwicklung von Natur und Landschaft aufzuzeigen, um einen funktionsfähigen Naturhaushalt zu sichern und um die Erholungsvorsorge zu gewährleisten. Der Landschaftsplan für die Gemeinde Elsteraue (Burgenlandkreis) wurde in den Jahren von 2005 bis 2006 erarbeitet. Die Biotopverbundplanung für den Burgenlandkreis bildete dabei eine wesentliche fachliche Vorgabe, die im Rahmen des Landschaftsplanes weiter präzisiert wurde. Dieser Prozess soll nachfolgend dargestellt werden. Aufgrund der Gemeindegröße wird beispielhaft der Bereich der Weißen Elster herausgegriffen

A note on similarity relations

AbstractA simple proof is given for the fact that the number of nonsingular similarity relations on {1, 2,… n}, for which the transitive closure of k blocks, equals (2n−2k−1n−1) −(2n−2k−1n)1 ⩽ k ⩽ n > ⧸2. In particular, this implies a recent result of Shapiro about Catalan numbers and Fine's sequence

a Business Cycle Perspective

This paper revisits the personal expenditure tax (PET), the most prominent version of a progressive consumption tax. The PET has a long intellectual tradition in economics, and the merits and demerits of this alternative to the personal income tax have been discussed at length. What has been missing in the literature so far, however, is a systematic account of its effect on the business cycle. This paper therefore seeks to add to the theoretical literature on the PET and the wider literature on automatic fiscal stabilizers by analyzing the PET's macroeconomic properties in a modern business cycle model. To this effect, the paper introduces a highly stylized PET into a standard New Keynesian DSGE model, derives a log-linear version of the model, and draws a comparison with the existing income tax. The model simulations show that the two tax systems lead to quite different macroeconomic dynamics. Furthermore, it is found that the PET yields welfare gains, relative to the income tax, for all the demand shocks considered. The PET yields welfare losses, however, under a supply shock

Alternating permutations and modified Ghandi-polynomials

AbstractThe presentation of alternating permutatioas via labelled binary trees is used to define polynomials H2n−1(x) as enumerating polynomials for the height of peaks in alternating permutations of length 2n−1. A divisibility property of the coefficients of these polynomials is proved, which generalizes and explains combinatirially a well-known property of the tangent numbers. Furthermore, a version of the exponential generating function for the H2n−1(x) is given, leading to a new combinatorial interpretation of Dumont's modified Ghandi-polynomials
