Corporate Real Estate Management: Evidence from German Companies

Based on a conceptual framework of factors representing and influencing corporate real estate management, this study is the first to be performed on the topic in Germany. The research shows that, despite their significant value and associated costs, real estate assets are at present seriously undermanaged by the vast majority of German companies. It seems that the international "bandwagon" toward active real estate management has not yet reached German firms. However, in some companies the function is evolving into a recognized management activity that requires a more formal and systematic approach.

Der soziologische Neo-Institutionalismus. Eine organisationstheoretische Analyse- und Forschungsperspektive auf schulische Organisationen

Der organisationssoziologische Neo-Institutionalismus ist bislang in den Erziehungswissenschaften kaum oder nur ansatzweise rezipiert worden. Dieser Befund steht in Kontrast zu der bedeutenden Stellung, die neo-institutionalistische Ansätze in der internationalen Organisationsforschung sowie auch in der deutschen organisationstheoretischen Diskussion einnehmen. Mit der Zielsetzung, das Potenzial einer neo-institutionalistischen Perspektive auf schulische Organisationen aufzuzeigen, gibt der vorliegende Beitrag zunächst einen Überblick über theoretische Grundzüge und aktuellere Weiterentwicklungen des soziologischen Neo-Institutionalismus. Anhand der zentralen neo-institutionalistischen Argumentationen und Erkenntnisse werden in einem zweiten Schritt die Situation des deutschen Schulwesens sowie aktuelle Schulreformvorhaben diskutiert. Dabei zeigt sich aus neo-institutionalistischer Sicht im Schulsektor eine Vielfalt möglicher Analyse- und Forschungsbereiche. (DIPF/Orig. )Organization-sociological neo-institutionalism has so far hardly been taken account of by educational science. This finding runs counter to the importance of neo-institutional approaches in international research on organization and in the German debate on organization theory. It is the author´s aim to point out the potential inherent in a neo-institutional perspective applied to school organization. She therefore sketches the theoretical foundations and present developments of sociological neo-institutionalism. Based on the central neo-institutional lines of reasoning and insights, she then discusses the situation of the German school system as well as present-day plans for school reform. It is shown that, from the neo-institutional point of view, the school sector offers a variety of possible fields for analysis and research. (DIPF/Orig.

The changing role of pesticides in pest management

Significant changes have occurred in the role of pesticides in pest management programmes since the publication of Carson's book Silent Spring in 1962. This discourse addresses the multitude of factors which contributed to these changes including such factors as policy and legislation, the public's perception of associated risks, population pressures, the availability of practical integrated pest management programmes, and perhaps most importantly, the constraints to IPM in Third World countries. While reliable statistics are difficult to obtain, the changing patterns in pesticide use in the tropical regions are also discussed. Finally, the future of pesticide use in developing countries is projected, as is the necessity of their use and expected impact

LHC Dark Matter Signals from Vector Resonances and Top Partners

Extensions of the Standard Model which address the hierarchy problem and dark matter (DM) often contain top partners and additional resonances at the TeV scale. We explore the phenomenology of a simplified effective model with a vector resonance $Z'$, a fermionic vector-like coloured partner of the top quark $T'$ as well as a scalar DM candidate $\phi$ and provide publicly available implementations in CalcHEP and MadGraph. We study the $pp \to Z' \to T'\overline{T'} \to t\bar{t}\,\phi\phi$ process at the LHC and find that it plays an important role in addition to the $T'\overline{T'}$ production via strong interactions. It turns out that the presence of the $Z'$ can provide a dominant contribution to the $t\bar{t}+E_T^{\text{miss}}$ signature without conflicting with existing bounds from $Z'$ searches in di-jet and di-lepton final states. We find that through this process, the LHC is already probing DM masses up to about 900 GeV and top partner masses up to about 1.5 TeV, thus exceeding the current bounds from QCD production alone almost by a factor of two for both particles.Comment: 32 pages, 15 figures, 3 table

Root Weevils

NYS IPM Type: Fruits IPM Fact SheetThere are more than 20 species of root weevils that attack strawberry in the United States. In New York, the three major species are the black vine weevil, Otiorhynchus sulcatus (Fabricius), the strawberry root weevil, 0. ovatus L., and the rough strawberry weevil, 0. rugostriatus Goeze. Root weevils are also pests of raspberries and rhododendrons

A W:B4C multilayer phase retarder for broadband polarization analysis of soft x-ray radiation \ud

A W:B4C multilayer phase retarder has been designed and characterized which shows a nearly constant phase retardance between 640 and 850 eV photon energies when operated near the Bragg condition. This freestanding transmission multilayer was used successfully to determine, for the first time, the full polarization vector at soft x-ray energies above 600 eV, which was not possible before due to the lack of suitable optical elements. Thus, quantitative polarimetry is now possible at the 2p edges of the magnetic substances Fe, Co, and Ni for the benefit of magnetic circular dichroism spectroscopy employing circularly polarized synchrotron radiatio

Access-Based Services for the Base of the Pyramid

One key challenge for consumers at the base of the pyramid (BoP) is access to products that could transform their livelihood, leading to nonconsumption as the dominant pattern. Previous studies have claimed that nonconsumption could be addressed with services offering access to goods without ownership. Drawing on expected utility theory, we conduct two experimental studies in rural India that provide the first empirical support for the idea that the availability of access-based services reduces nonconsumption at the BoP. Additionally, we show that this effect is explained by BoP consumers’ expected utility assessment as reflected in their perception of access being more affordable and entailing less financial risk than ownership. We also demonstrate that access temporality, an important configurational variable for access-based service providers, affects the degree to which nonconsumption can be decreased. Compared to short-term access, BoP consumers perceive long-term access to be too similar to ownership in terms of affordability and financial risk, which causes them to refrain from purchasing. Overall, the results suggest that access-based services represent a viable alternative for addressing nonconsumption at the BoP. However, service providers should be aware that short-term access is required to gain acceptance among BoP consumers

Electron spin tomography through counting statistics: a quantum trajectory approach

We investigate the dynamics of electron spin qubits in quantum dots. Measurement of the qubit state is realized by a charge current through the dot. The dynamics is described in the framework of the quantum trajectory approach, widely used in quantum optics, and we show that it can be applied successfully to problems in condensed matter physics. The relevant master equation dynamics is unravelled to simulate stochastic tunneling events of the current through the dot.Quantum trajectories are then used to extract the counting statistics of the current. We show how, in combination with an electron spin resonance (ESR) field, counting statistics can be employed for quantum state tomography of the qubit state. Further, it is shown how decoherence and relaxation time scales can be estimated with the help of counting statistics, in the time domain. Finally, we discuss a setup for single shot measurement of the qubit state without the need for spin-polarized leads.Comment: 23 pages, 10 figures, RevTeX4, submitted to PR
