The Research Data Centre of the Centre for European Economic Research (ZEW-FDZ)
Das Zentrum fĂŒr EuropĂ€ische Wirtschaftsforschung (ZEW) in Mannheim stellt eine Reihe seiner
ForschungsdatensĂ€tze externen Wissenschaftlern zur VerfĂŒgung. Das ZEW folgt damit
den Empfehlungen der âKommission zur Verbesserung der informationellen Infrastruktur
zwischen Wissenschaft und Statistikâ und unterstĂŒtzt so die Weiterentwicklung der empirischen
Wirtschafts- und Sozialforschung. Im November 2012 ist das ZEW-FDZ vom Rat fĂŒr
Sozial und Wirtschaftsdaten (RatSWD) akkreditiert worden.
Bei den im ZEW-FDZ angebotenen ZEW Forschungsdaten handelt es sich um Mikrodaten von
ZEW Unternehmensbefragungen, ZEW Expertenbefragungen oder ZEW Personenbefragungen.
Die Daten einiger ZEW-Befragungen werden externen Wissenschaftlern in einer faktisch
anonymisierten Form als Scientific-Use-Files zur VerfĂŒgung gestellt. Neben der Nutzung der
Scientific-Use-Files können externe Forscher einen Antrag auf Nutzung von formal anonymisierten
ZEW-Daten stellen, mit denen sie in den FDZ-RĂ€umen des ZEW arbeiten dĂŒrfen.
Formal anonymisiert bedeutet, dass die DatensÀtze weder Namen noch Adressen, aber ansonsten
alle Originalangaben der Befragten enthalten. Die formal anonymisierten Daten befinden
sich dazu auf einem Stand-alone-Rechner ohne Netzwerkanbindung, von dem keine
Daten heruntergeladen werden können. FĂŒr das Mannheimer Innovationspanel (MIP) wurden
zudem absolut anonymisierte Education-Use-Files fĂŒr die Nutzung in der Lehre erstellt.
Das ZEW-FDZ schlieĂt an die bisherige Praxis des ZEW an, eigene Erhebungsdaten an externe
Wissenschaftler weiterzugeben. Vor dem Start des ZEW-FDZ im Januar 2013, stellte das ZEW
etwa 280 Wissenschaftlern vom ZEW erhobene Forschungsdaten zur VerfĂŒgung; die meisten
sind Nutzer des Mannheimer Innovationspanels (250). Das ZEW wird sein Datenangebot fĂŒr
externe Wissenschaftler laufend erweitern. Dies gilt auch fĂŒr Daten zukĂŒnftiger Erhebunge

Cutting Through the Online Review Jungle â Investigating Selective eWOM Processing
Consumers frequently rely on online reviews, a prominent form of electronic word-of-mouth (eWOM), before making a purchase decision. However, consumers are usually confronted with hundreds of reviews for a single product or service, as well as rich information cues on online review websites (review texts, helpfulness ratings, author information, etc.). In turn, consumers face more information cues on online review websites than they can or want to process, and are likely to proceed selectively. This paper investigates selective processing of such eWOM information cues. Results of Study 1, an exploratory study using verbal protocols, confirm that consumers display selective eWOM processing patterns and are able to articulate them. Study 2 develops and applies a measurement instrument to capture these patterns. A subsequent cluster analysis on members of a large-scale online panel (N = 2,295) indicates five prominent eWOM processing types, termed âThe Efficientsâ, âThe Meticulousâ, âThe Quality-Evaluatorsâ, âThe Cautious Criticsâ, and âThe Swift Pessimistsâ. Insights of this research can help firms to better understand consumers' eWOM processing and improve the user-friendliness of online review websites

Examining Biased Assimilation of Brand-related Online Reviews
This paper examines the impact of pre-existing brand attitudes on consumer processing of electronic word-of-mouth (eWOM). This topic is particularly important for brands that simultaneously possess strongly pronounced proponents as well as opponents. Two experimental studies using univalent (study 1, N = 538) and mixed (study 2, N = 262) sets of online reviews find indications for biased assimilation effects of eWOM processing. Consumers perceive positive (negative) arguments in online reviews as more (less) persuasive when having a positive (negative) attitude towards the brand. Perceived persuasiveness in turn influences behavioral intentions and acts as a mediator on the relationship between attitude and behavioral intentions. We examine two moderators of this effect. When priming individuals to focus on other consumers (vs. a self-focus prime), the biased assimilation effect is weaker (study 3a, N = 131). In contrast, we show that biased assimilation becomes stronger under conditions of high (vs. low) cognitive impairment (study 3b, N = 124). Our findings contribute to the literature on the relationship between eWOM and brands and advance our understanding of potential outcomes of brand polarization
Perfusion lung scintigraphy for the diagnosis of pulmonary embolism: a reappraisal and review of the Prospective Investigative Study of Acute Pulmonary Embolism Diagnosis methods.
Beam Test of BTeV Pixel Detectors
The silicon pixel vertex detector is one of the key elements of the BTeV
spectrometer. Detector prototypes were tested in a beam at Fermilab. We report
here on the measured spatial resolution as a function of the incident angles
for different sensor-readout electronics combinations. We compare the results
with predictions from our Monte Carlo simulation.Comment: 7 pages, 5 figures, Invited talk given by J.C. Wang at "Vertex 2000,

The Cape Triage Score - a triage system for South Africa
The Cape Triage Score (CTS) has been derived by the Cape Triage Group (CTG) for use in emergency units throughout South Africa. It can also be used in the pre-hospital setting, although it is not designed for mass casualty situations. The CTS comprises a physiologically based scoring system and a list of discriminators, designed to triage patients into one of five priority groups for medical attention. Three versions have been developed, for adults, children and infants. As part of the ongoing assessment process the CTG would value feedback from the readers of this Journal
On Hausdorff dimension of the set of closed orbits for a cylindrical transformation
We deal with Besicovitch's problem of existence of discrete orbits for
transitive cylindrical transformations
where is an
irrational rotation on the circle \T and \varphi:\T\to\R is continuous,
i.e.\ we try to estimate how big can be the set
D(\alpha,\varphi):=\{x\in\T:|\varphi^{(n)}(x)|\to+\infty\text{as}|n|\to+\infty\}.
We show that for almost every there exists such that the
Hausdorff dimension of is at least . We also provide a
Diophantine condition on that guarantees the existence of
such that the dimension of is positive. Finally, for some
multidimensional rotations on \T^d, , we construct smooth
so that the Hausdorff dimension of is positive.Comment: 32 pages, 1 figur
Territorial Tactics: The Socio-spatial Significance of Private Policing Strategies in Cape Town
This paper analyses the policing strategies of private security companies operating in urban space. An existing literature has considered the variety of ways that territory becomes of fundamental importance in the work of public police forces. However, this paper examines territory in the context of private security companies. Drawing on empirical research in Cape Town, it examines how demarcated territories become key subjects in private policing. Private security companies are responsible for a relatively small section of the city, while in contrast the public police ultimately have to see city space as a whole. Hence, private policing strategy becomes one of displacement, especially of so-called undesirables yielding a patchworked public space associated with private enclaves of consumption. The conclusions signal the historical resonances and comparative implications of these political-legal-security dynamics. © 2013 Urban Studies Journal Limited
