Coaching für einen Dozenten in einer Weiterbildungseinrichtung

Coaching with a lecturer in a retraining institution The author presents an individual coaching with an IT-lecturer, who recently has begun to work as lecturer. His motive was a conflict with a member of the course. His communication and leading style was discussed and improved by new behavior patterns. After that, in a communication training with the total group, who had also difficulties with this group member, a reintegration of this person was achieved by a role play and the atmosphere in the group was relieved.

LIMITED ASSET MARKET PARTICIPATION,STICKY WAGES,AND MONETARY POLICY

A small amount of nominal wage stickiness makes limited asset market participation (LAMP) irrelevant for the design of monetary policy. Recent research argues that LAMP could invert the slope of the IS curve in otherwise standard New Keynesian models. This, in turn, implies that optimal monetary policy rules should be passive. We show that the so‐called inverted aggregate demand logic (IADL) relies on nominal wage flexibility. Outside of extreme parameterizations, wage stickiness prevents the inversion of the slope of the IS curve. Hence, LAMP does not generally alter the trade‐offs faced by a welfare maximizing Central Bank, and for this reason it does not fundamentally affect the design of optimal simple rules and optimal monetary policy.

Interest‐Talk as Access‐Talk: How Interests are Displayed,Made and Down‐played in Management Research

This paper addresses the methodological issue of how researchers gain access and build trust in order to conduct research in organizations. It focuses, in particular, on the role of interests (what actors want or what they stand to gain or lose) in the research relationship. The analysis shows how notions of interests, stake and motive were managed during an action research study in a UK subsidiary of a multinational corporation. The study uses an approach to discourse analysis inspired by the field of discursive psychology to identify four discursive devices: stake inoculation; stake confession; stake attribution; and stake construction. The paper contributes to the understanding of research methodology by identifying the importance of interest‐talk in the process of doing management research.     

Automatically Detected Nonverbal Behavior Predicts Creativity in Collaborating Dyads

In the current study we administered a creative task in which two people collaboratively generated novel strategies to conserve resources. During this task, the nonverbal behavior of 104 participants in 52 pairs was tracked and recorded using the Kinect computer vision algorithm. We created a measure of synchrony by correlating movements between the two dyad members, and showed that synchrony occurred—that is, correlations decreased when we increased delay between the recorded movements of pair members. We also demonstrated a link between nonverbal synchrony and creativity, as operationalized by the number of new, valid ideas produced. Linear correlations demonstrated a significant relationship between synchrony and creativity. Finally, models using synchrony scores as input predicted whether dyads were high or low in creativity with a success rate as high as 86.7 % in the more exclusive subsets. We discuss implications for methodological approaches to measuring nonverbal behavior and synchrony, and suggest practical applications which can leverage the current findings.

Variability of water quality,metals and phytoplankton community structure in urban stormwater ponds along a vegetation gradient

Stormwater Ponds (SPs) are common throughout urbanizing environments, yet their ecological role has not been well established. SPs are primarily designed for hydrological control of stormwater, but many are also designed to attenuate the quality of runoff prior to discharge. Thus, SPs likely serve as an important land-water linkage between terrestrial and aquatic systems in urban areas. In this study, we characterized 22 SPs and 3 natural reference ponds from Durham Region, Ontario, Canada representing a gradient in emergent plant cover. There was high variability and wide ranges in water quality parameters among SPs. The percentage of impervious surface served as a measure of urbanization intensity, and was a significant driver of conductivity, chloride and total suspended solids regardless of emergent vegetation cover. In fact, only water temperature (r?=??0.61) was found to significantly correlate with vegetation cover. This suggests a minimal role for emergent vegetation in mediating SP water quality. SPs had notably higher conductivity and runoff-metals (Cu, Zn, Pb, and Cr) than reference ponds, but nutrients (Total P and Total N) and algal biomass did not significantly differ between SPs and reference ponds. Dominant phytoplankton groups included blue-green and euglenid algae, both of which are indicators of eutrophic and high organic systems, respectively. The blue-green genus Microcystis was detected in all ponds, and was the dominant taxon in most SPs. This raises concern that SPs may serve as reservoirs of toxin-producing algae. Multivariate analyses of metals, water quality variables and algal species composition showed considerable dissimilarity among SPs, yet comparably high similarity among reference ponds. This indicates that SPs are dynamic and diverse systems despite their engineered origins. Such broad gradients in water quality characteristics also imply variable impacts to receiving waters in the same region.     

A systematic review of the relationship between urban agriculture and biodiversity

Urban agriculture is a unique form of agriculture that can provide fresh, local produce for urban residents, and may benefit biodiversity by decreasing the need to expand agriculture into natural areas as well as enhancing biodiversity in urban areas. However, although urban agriculture is also often cited as promoting biodiversity in urban areas, the extent of empirical evidence for such claims has not been studied. Here we systematically review the relationship between urban agriculture and biodiversity in the scientific literature. We strictly define urban agriculture as areas in cities that grow produce specifically for human consumption. We examined 148 papers from 2000 to 2017, of which only 24 studies fit our definition of urban agriculture, and of those, only 18 both involved urban agriculture and measured biodiversity. Of the studies that did measure biodiversity, some showed increases in diversity compared to urban vacant lots, but other showed no difference. Moreover, these studies were mostly focused on plants and invertebrates and were conducted almost exclusively in North America. In order to use the generalization that urban agriculture will have a positive influence on urban biodiversity, more studies will need to be conducted across a wider geographic range worldwide (particularly in developing countries in the tropics) and on a greater diversity of species and taxa (e.g., herpetiles, birds and small mammals). Such studies will likely increase in conservation importance as urban expansion and agricultural demands increase globally.
