SOGRO – Sofortrettung bei Großunfall
In Katastrophenfällen sind eine schnelle und
effiziente Erstversorgung der Verletzten sowie
eine koordinierte und zielgerichtete Weiter ver -
sorgung dieser von zentraler Bedeutung für
eine erfolgreiche Sofortrettung. Im vom Bun -
desministerium für Bildung und Forschung
(BMBF) geförderten Forschungsprojekt SOGRO
werden der Einsatz von Informations- und Kom -
munikationstechnologien (IKT) und dessen Aus -
wirkungen auf den Rettungsprozess erforscht.
Auf Basis moderner IKT wird eine durchgängige
Informationskette von der Erfassung, Sichtung
und Versorgung der Verletzten, der Nachver -
folg barkeit von Transportwegen bis hin zur
Klinikaufnahme aufgebaut, um so zu einer effizienteren
Erstversorgung der Verletzten beizutragen.
Der Lehrstuhl führt in diesem Projekt
die ökonomische Begleitforschung durch, dazu
gehören u. a. die ökonomische Bewertung der
erforschten Rettungstechnologien sowie die
Entwicklung tragfähiger Geschäftsmodelle zur
erfolgreichen Markteinführung.
Utilization Levels and Productivity Effects of
Information Technology Investments
Explaining productivity effects of factor inputs
is an important research topic since improving
the general standard of living is highly dependent
on the ability to grow businesses, industries
and economies, thereby increasing output.
While the productivity effects of labor and noninformation
technology capital and their interrelations
in the transformation process to output
have recently become better understood,
researchers still struggle to explain the full productivity
effects of investments in information
technology (IT) capital. Explaining these full
effects is critical because, increasingly, IT enable
innovation, is the foundation for efficient intraand
inter-organizational processes, and determines
how industries conduct business. In the
last twenty years and especially with the advent
of the information age, IS researchers have
made good progress in laying the basis for an
explanatory model that includes IT as a separate
input factor to explain pro ductivity effects
of IT investments by extending standard production
theoretical models using e.g. the Cobb-
Douglas or Translog production functions.
These standard models typically assume complete
or at least constant factor utilization.
Given fluctuations in the utilization of input factors
– especially in severe economic downturns
as we currently observe – and absent the
opportunity to adjust the IT capital input in the
short term, there are numerous measurement
issues that have to be analyzed and dealt with
in order to extend the models and derive more
accurate productivity estimates of IT investments.
Optimal global sourcing of software development
projects
With the main focus on cost reduction in valua-
tion of sourcing alternatives, risk and risk diversification
effects are often inadequately considered
or completely neglected in decisions associated
with global sourcing decisions for software
development projects. This systematically
results in poor decisions. In this project, we
analyze sourcing costs and associated risks as
well as interdependencies among both sites
and projects. The special focus here is on the
identification of correlation effects between
sites. A normative model shall be developed,
based on e.g. modern portfolio theory, and
validated using data from IT services providers.
IT events and their effect on prices and markets
Securities exchanges are becoming increasingly
automated. Over the course of the past years,
most major exchanges have upgraded their
trading infrastructure to accommodate the
increase in algorithmic trading. E.g. about half
of all trades executed on XETRA, the fully electronic
cash market system operated by Deut -
sche Börse, are generated by algorithmic trading
engines. The effects of IS (in terms of infrastructure
or in terms of automated trading on
the market outcome as well as on the development
of the financial markets in general) are so
far not well understood. In this project, using
primarily the event study methodology, IT-driven
events will be analyzed with respect to
their different impacts on financial markets.
At the same time, we address and explore the
methodological challenges associated with
applying the event-study methodology to financial
market data.
Web services platform to analyze mass data
With the dramatic increase in the speed and
availability of computer networks, a significant
proportion of all economic activities is now conducted
electronically. In particular, the field of
financial trading has seen an unprecedented
increase in both the number of participants and
the volume of trades conducted via electronic
markets. As a result, high frequency data has
become increasingly available for historical
analysis by researchers in fields like econometrics,
finance and accounting. Analyzing such
datasets requires – at least – expert domain
knowledge (e.g. in finance and microeconomics),
experience, and IT skills. In addition to
being able to identify suitable data sources and
specify the right search criteria, users must be
able to perform a wide range of analysis functions
(statistical, data mining, language processing)
and present results in a suitable form
(e.g. through visualization or report creation).
Analysis processes cannot be determined in
advance as users tend to perform tasks in a
piecemeal fashion. When the type of analysis
is complex, users spend a lot of effort cleaning,
reading and interpreting the data, converting
datasets from one format to another, copying
some results from one file to another, and
merging datasets with different semantics.
These activities increase analysis time and the
risk of errors. In this project, an environment
will be developed that supports a Service-
Oriented Architecture (SOA), making it possible
to define re-usable and interoperable software
components as web services which can manipulate
the elements of an underlying, eventbased
data model. Such a model allows a
coherent representation of market activities –
particularly high-frequency market and news
data – as events.
