»Flexible Arbeitspraktiken: Eine Analyse aus pragmatischer Perspektive«. Traditional human resource management (HRM) research can hardly relate to today's developments in the world of work. Organizational boundaries are blurred because of the complexity due to globalization, digitalization, and demographic changes. In practice, new ways of organizing work can be found that depend on the specifics of the work situation. In this paper, we build on the economics of convention (EC) to elaborate on the current challenges HRM scholarship is confronted with and provide a theoretical lens that goes beyond the tension between market and bureaucracy principles in actual employment settings. We apply EC’s situationalist methodology to examples of the challenging coordination of flexibility in the workplace. We explain two hybrid forms of coordination – compromises and local arrangements – and highlight the dynamics of employment practices in organizations related to these forms. Thereby, we show that different modes of coordination in employment are applied in a fluctuating manner that depends on the specific situations. In doing so, we further seek to remind HRM scholars of the fruitfulness of the pragmatist perspective in analyzing work practices, as well as extending its conceptual toolkit for future analysis.
This paper studies option pricing based on a reverse engineering (RE) approach. We utilize artificial intelligence in order to numerically compute the prices of options. The data consist of more than 5000 call- and put-options from the German stock market. First, we find that option pricing under reverse engineering obtains a smaller root mean square error to market prices. Second, we show that the reverse engineering model is reliant on training data. In general, the novel idea of reverse engineering is a rewarding direction for future research. It circumvents the limitations of finance theory, among others strong assumptions and numerical approximations under the Black–Scholes model.
This paper develops a new methodology in order to study the role of dynamic expectations. Neither reference-point theories nor feedback models are sufficient to describe human expectations in a dynamic market environment. We use an interdisciplinary approach and demonstrate that expectations of non-learning agents are time-invariant and isotropic. On the contrary, learning enhances expectations. We uncover the “yardstick of expectations” in order to assess the impact of market developments on expectations. For the first time in the literature, we reveal new insights about the motion of dynamic expectations. Finally, the model is suitable for an AI approach and has major implications on the behaviour of market participants.
Collaborative apparel consumption is proposed as more sustainable alternative to conventional consumption. The purpose of this study is the exploration of consumers’ motives to participate in collaborative apparel consumption. Findings suggest that consumers’ intention to participate in collaborative apparel consumption is mainly influenced by financial benefits, convenience and sustainability awareness.
Successful digital offerings are created at the intersection of what technologies can deliver and what customers want and will pay for. That point of intersection, however, has proved to be elusive. To find it, companies must experiment repeatedly, cocreate with customers, and assemble cross-functional development teams - and the insights gleaned along the way must be shared internally.
In this article, we discuss how several of the nearly 200 companies we've studied have built and exercised these capabilities. We also take a close look at how one company, Schneider Electric, is using them to acquire and share customer insights.
This paper generalizes the theory of policy uncertainty with the new literature on rational inattention. First, the model demonstrates that inattention is dependent on the signal variance and the policy parameter. Second, I discover a novel trade-off showing that a policy instrument mitigates attention. Third, the policy instrument is non-linear and reciprocal to both the size and variance of the signal. The unifying theory creates new implications to economic theory and public policy alike.
We report an investigation into the distribution of copper oxidation states in oxide films formed on the surfaces of technical copper. The oxide films were grown by thermal annealing at ambient conditions and studied using Auger depth profiling and UV–Vis spectroscopy. Both Auger and UV–Vis data were evaluated applying multivariate curve resolution (MCR). Both experimental techniques revealed that the growth of Cu2O dominates the initial ca. 40 nm of oxide films grown at 175 °C, while further oxide growth is dominated by CuO formation. The largely coincident results from both experimental approaches demonstrates the huge benefit of the application of UV–Vis spectroscopy in combination with MCR analysis, which provides access to information on chemical state distributions without the need for destructive sample analysis. Both approaches are discussed in detail.
Homogeneous and monodispersed furan functionalised melamine-formaldehyde particles were produced. As a precursor, 2-chloro-1,3,5-triazine-2,4-diamine (Mel) was selectively substituted with 2-aminomethyl furan (Fu) units in a convenient one step reaction. The pure reaction product Fu-Mel, which was used without further purification, was reacted with formaldehyde by conventional sol-gel condensation in aqueous medium to yield chemically homogenous, spherically shaped and monodispersed particles. The particles were analysed using ATR-FT-IR, Raman, 1H and 13C NMR spectroscopy, TGA, SEM and DSC measurements. The reactivity of the furan groups located at the particle surface was studied by performing a thermoreversible Diels-Alder cycloaddition reaction with bis-maleimide coupling agents. The formed networks showed thermoreversible behaviour, which was characterised by dynamic IR and DSC measurements.
Today many vertical retailers are operating different sales channels at the same time and are respon-sible for the range of products in all sales channels. The purpose of this paper is to examine whether for vertical fashion retailers a format-specific assortment policy can be observed on the German mar-ket. To investigate this topic in addition to secondary data of a literature research, quantitative prima-ry data was collected through a structured observation by conducting store checks. The combination provides insights into the research topic, allows to build hypotheses and to get a current and specific answer on the research topic. The study revealed all vertical retailers exploit the advantage of unlim-ited capacity of the online shop by offering in this channel mainly the broadest and deepest assort-ment. Within the retail store the vertical retailers focus on offering full-price goods for the current season in full size sets. Compared to the online shop here are less styles sophisticated presented and adjusted on the sales floor. For the outlet channel all brands showed a higher density of products and at least a price reduction of 30 per cent. The present paper is limited by time, depth and language of secondary data collection. As the study only conducted quantitative data within limited observations additional visual data over a longer period is necessary.
The purpose of this paper is to assess if the strategy development of the fashion industry is oriented to the long or short term. Following the theory of dynamic capabilities, this paper argues that a long term strategic orientation can be observed in corporate foresight activities. A multi methodological research approach is chosen to answer the research question. The findings suggest that the fashion industry is lagging behind other industries in terms of future orientation and therefore long-term strategy development, even though the challenges in the business environment are not perceived as less relevant.
