Dit rapport is een introductiepaper van het International Small Business Congress 2002, dat gehouden zal worden in Amsterdam van 27 tot en met 30 oktober 2002. Aangezien de euro op 1 januari 2002 geĂŻntroduceerd wordt, zal speciale aandacht worden besteed aan de economische integratie in Europa en de gevolgen daarvan voor het kleinbedrijf.
Tetraquark resonances computed with static lattice QCD potentials and scattering theory
We study tetraquark resonances with lattice QCD potentials computed for two
static quarks and two dynamical quarks, the Born-Oppenheimer approximation and
the emergent wave method of scattering theory. As a proof of concept we focus
on systems with isospin , but consider different relative angular
momenta of the heavy quarks. We compute the phase shifts and search for
\mbox{S} and \mbox{T} matrix poles in the second Riemann sheet. We predict
a new tetraquark resonance for , decaying into two mesons, with
quantum numbers , mass
and decay width .Comment: 7 pages, 6 figures, 1 table, Proceedings of the 35th International

A portable laser system for high precision atom interferometry experiments
We present a modular rack-mounted laser system for the cooling and
manipulation of neutral rubidium atoms which has been developed for a portable
gravimeter based on atom interferometry that will be capable of performing high
precision gravity measurements directly at sites of geophysical interest. This
laser system is constructed in a compact and mobile design so that it can be
transported to different locations, yet it still offers improvements over many
conventional laboratory-based laser systems. Our system is contained in a
standard 19" rack and emits light at five different frequencies simultaneously
on up to 12 fibre ports at a total output power of 800 mW. These frequencies
can be changed and switched between ports in less than a microsecond. The setup
includes two phase-locked diode lasers with a phase noise spectral density of
less than 1 \mu rad/sqrt(Hz) in the frequency range in which our gravimeter is
most sensitive to noise. We characterize this laser system and evaluate the
performance limits it imposes on an interferometer.Comment: 8 pages, 11 figures; The final publication is available at

ENGINEERING KNOWLEDGE-INTENSE, PERSONORIENTED SERVICES â A STATE OF THE ART ANALYSIS
This paper provides a state-of-the-art analysis of service engineering (SE) approaches for knowledgeintense person-oriented (KIPO) services, focussing on IT-enabled provision of such services. Key attributes are derived that distinguish KIPOs from other services. These attributes are integrated in a framework with regard to their applicability on KIPOs development and used for a systematic literature review. KIPOs are of high economic relevance, yet they are laggards in terms of realization of IT potentials. As the most value-creating activities in service provision are bound to persons or personal knowledge, KIPOs design is complicated. The analysis reveals several gaps in SE research. In particular, identified shortcomings of existent approaches are an insufficient level of detail, i.e. no concrete actions or methods for deployment are described, a lack of practical corroboration as well as insufficient IT support. Further, current approaches are not sufficiently equipped to handle the interplay between people-bound activities and technical components. This paper contributes to IS research by clearly identifying these gaps in SE methods. It further provides researchers with ideas for future research activities and guides practitioners in selecting methods that serve as candidates to be integrated into KIPOs development in order to leverage IT potentials more systematically and efficiently
Managing Complex Work Systems via Crowdworking Platforms: How Deutsche Bank Explores AI Trends and the Future of Banking with Jovoto
Crowdsourcing has evolved into a powerful new instrument for companies. In the last years, crowdworking platforms that manage work systems as intermediaries between crowdsourcers and crowd workers have increasingly been used. Nevertheless, they currently often manage rather simple work systems. Although they have the potential for managing more complex ones, there is still little knowledge how this can be done and what measures are necessary to do so. To explore this question in more detail, we investigate three seminal projects that Deutsche Bank completed with the crowdworking platform Jovoto and that aimed at exploring AI trends and developing concepts for the future of banking. We derive measures necessary for the successful management of complex work systems and provide a model as guidance for both companies and crowdworking platform operators. With our findings, we extend current knowledge in the realm of IS, organizational theory, and platform ecosystem
One for All? Managing External and Internal Crowds through a Single Platform - A Case Study
Whereas crowdsourcing as a topic has often been addressed in recent literature, web-based crowdworking platforms that manage the interface between crowdsourcers and crowdworkers have not received much attention so far. Furthermore, most of these platforms focus on either the management of external or internal crowds; platforms that handle both groups are rare. This paper investigates such a provider: the German company Across Systems. It uses a hybrid model, offering an individual âmini crowdworking platformâ that enables the simultaneous government of external and internal crowds as well as a more traditional marketplace crowdworking platform (crossMarket) where supply and demand meet. Using a single-case study approach, the main contribution of this paper is to shed light on a model that has the potential to change the current crowdworking platform market. We show that managing both external and internal crowds on one platform can increase the acceptance, quality and speed of task completion
