In Anlehnung an die Kontinuit{\"a}tstheorie (Atchley 1989) wird davon ausgegangen, dass Individuen, die mit ihren Strukturen und Leistungen zufrieden sind, l{\"a}nger im Beruf verweilen. Daher wird untersucht, ob Motivation und wahrgenommene Leistungsf{\"a}higkeit einen Einfluss auf den Weiterbesch{\"a}ftigungswunsch haben. Dar{\"u}ber hinaus soll die Frage beantwortet werden, ob Faktoren, die einen positiven Einfluss auf Motivation und Leistungsf{\"a}higkeit haben, auch einen direkten Einfluss auf die Weiterbesch{\"a}ftigung zeigen. Neben objektiven Faktoren wie Unternehmensgr{\"o}ße und Stellung im Beruf werden subjektive Faktoren, wie z.B. Einsch{\"a}tzung der Anerkennung, der Anforderungen und der Sinnhaftigkeit der T{\"a}tigkeit, auf ihren Erkl{\"a}rungsbeitrag, {\"u}berpr{\"u}ft. Die folgende Analyse basiert auf einer Befragung, die im Mai 2008 zusammen mit dem Bundesinstitut f{\"u}r Bev{\"o}lkerungsforschung (BiB) durchgef{\"u}hrt wurde. Sie erm{\"o}glicht, die Weiterbesch{\"a}ftigungsw{\"u}nsche im Alter, die vorhandene Arbeitsmotivation und den Gesundheitszustand zu identifi zieren. Die zentralen Ergebnisse der statistischen Analyse zeigen, dass bei M{\"a}nnern eine hohe Motivation mit dem Wunsch nach einer Weiterbesch{\"a}ftigung im Rentenalter verkn{\"u}pft ist.

While the group of elderly workers grows, their sustainment will become more important in future (e.g. H{\"o}hn et al. 2008; Dittrich et al. 2011). Especially in combination with an ageing population and a later entrance into the labour market a future shortfall of active workers can be assumed. Germany - as one example of such countries - has only a limited number of options that policy makers and companies can use in the coming decades. One of these is the increased use of the three growing segments in the population: older people, immigrants and an increased participation of women in the labour market. This study focuses the first segment as a potential work force. When promoting that a higher employment rate of older workers can be considered as serious alternative for dealing with the current shortfall of skilled labour force, the motivation of these workers has to be investigated. The works of Alavinia et al. (2007) and Wang, Shultz (2010), which discuss factors influencing the decision to prolong the working age, can be used as starting point. In this context, we analyse the German labour market as an example for a developed country. For the analysis, we use a representative data set of the Federal Institute for Population Research of Germany from published in2008. Here, 1,500 employees (blue collar workers, white collar workers, civil servants) aged between 55 and 64 years were asked about their work situation, motivation and related factors (e.g. further education, job rewards; B{\"u}sch et al. 2010). During the data analysis we identify groups of elderly workers using cluster analysis (e.g. Cormack 1971) to develop recommendations for companies. By using existing work motivation and related findings, as well as a representative empirical data set, our study reveals a possibility to identify, classify, and enhance the motivation of workers at the end of their career. This is necessary to keep the quality of goods and service production at an appropriate level. The value of the paper comes from the large number of respondents of the data set and the high relevance of the German situation for other developed countries. At the end, powerful recommendations for companies how to involve and motivate elderly workers for longer periods of employment can be derived.}, language = {en} } @incollection{DittrichBueschMicheel2011, author = {Dittrich, Dennis Alexis Valin and B{\"u}sch, Victoria and Micheel, Frank}, title = {Working beyond retirement age in Germany: The employee's perspective}, series = {Older workers in a sustainable society}, booktitle = {Older workers in a sustainable society}, publisher = {Peter Lang}, address = {Frankfurt am Main}, isbn = {978-3631614808}, publisher = {SRH Berlin University of Applied Sciences}, pages = {1 -- 14}, year = {2011}, abstract = {The social security system and the labour market face new challenges due to demographic change.

It works for functional and non-functional properties, it may consider both, hardware and software, and it allows for a description of composition anomalies.

In an age of Bring-Your-Own-Device, small businesses through to globally operating companies increasingly support their employees and customers with SaaS-applications that allow access to internal and external business information. Whether employees are in the office, at a client facility, at home or on the road, they need fast, easy access to business applications with any type of device. SaaS offers companies an interesting alternative to classical on-premise IT solutions. Cloud computing provides innovative applications, high connectivity and performance, cost reduction, flexibility and fast time to market with a minimum of effort. Cloud computing is a special form of outsourcing that has its roots in the fifties. Ten years ago similar concepts to cloud computing e.g. Application Service Providing (ASP) appeared and failed. But it seems that the willingness to use cloud computing is now much higher and the cost pressure effects of the financial crisis also motivate decision makers in companies to focus on cloud computing.

It describes several types of SaaS marketplaces using different business models to bring together customers and providers. It shows that SaaS marketplaces are two-sided and demonstrates how platforms are emerging that bundle features into significant value propositions for both sides.

It examines how the level of innovation can remain high despite a free exchange of intellectual property - fashion designs - within the industry: The importance of innovation for a fashion business in the industry is determined by the choice of it's competitive strategy. That is, either to be an innovator who creates fashion innovations or to be an imitator who adopts them once they have proven their ability to prevail in the market. The success of innovators depends largely on their ability to react to fashion trends, reinforced by the social role of fashion products and to the extent of their potential to confer status on the owner. Thus the duration of a temporary monopoly gained by an innovation is limited not only by the market entrance of imitators - a period of time that can be prolonged by making use of industrial property rights protection - but also by the constant changes in fashion, a process barely affected by the utilization of intellectual property rights protection. A monopoly maintained by using intellectual property rights might very well not extend the product life cycle beyond the limits posed by the shifting changes of fashion; moreover, an extended life cycle maintained in these circumstances could seriously limit the innovators agility in satisfying consumer demand in line with fashion trends and provoke an inappropriate allocation of resources to developing unfashionable innovations, resulting in a much greater risk of product failure.}, language = {en} } @inproceedings{PittkeLeopoldMendlingetal.2012, author = {Pittke, Fabian and Leopold, Henrik and Mendling, Jan and Tamm, Gerrit}, title = {Enabling Reuse of Process Models through the Detection of Similar Process Parts}, series = {Business Process Management Workshops}, booktitle = {Business Process Management Workshops}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-642-36284-2}, url = {http://nbn-resolving.de/urn:nbn:de:0298-opus4-40}, pages = {586 -- 597}, year = {2012}, abstract = {Many companies use business process modeling to support various improvements initiatives leading to an increasing number of process models.
