The Future of Co-Creation
2011
The objective of this article is to provide a brief summary of the key directions in value co-creation research that have emerged in the last 10 years. It points to several emerging streams in value co-creation research including: i) general management perspective; ii) new product development and innovation; iii) virtual customer environments; iv) service science and service-dominant logic (SDL) of marketing; and v) international markets and entrepreneurship, with a focus on the general management and innovation perspectives. In addition, the article points to another emerging new direction focusing on business co-creation. The development of business co-creation frameworks integrating the …

Performance under Pressure on the Court: Evidence from Professional Volleyball
2018
This study analyzes how psychological pressure affects performance. It refers to the discussion on differences between choking, i.e., an acute performance decline under pressure and under- performance under pressure. When performance outcomes are not defined binary even slight performance decrements can have huge consequences for future career. To study the conse- quences of psychological pressure on performance, we employ data on the serving performance of 213 professional volleyball athletes in 226 matches. We do not find any evidence for the existence of severe performance decrements under pressure (i.e. choking). However, athletes serve less effectively under pressure, i.e., they serve …
Hedging spark spread risk with futures
2018
Abstract This paper discusses the spark spread risk management using electricity and natural gas futures. We focus on three European markets in which the natural gas share in the fuel mix varies considerably: Germany, the United Kingdom, and the Netherlands. We find that spark spread returns are partially predictable, and consequently, the Ederington and Salas (2008) minimum variance hedging approach should be applied. Hedging the spark spread is more difficult than hedging electricity and natural gas price risks with individual futures contracts. Whereas spark spread risk reduction for monthly periods produces values of between 20.05% and 48.90%, electricity and natural gas individual hedg…
Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS
2010
The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets—given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the sho…
Psychological interventions to fight against the burden of the informal caregivers
2011
Informal care has been conceptualized as a vital stress factor, which jointly with its chronic character and the lack of foresight about the time of its finalization, has been associated to the negative repercussions on the physical and psychological wellbeing of the informal caregiver. This situation has been generically denominated with the overall term of caregiver burden. Burden is associated with depression and anxiety as well as with abandonment and mistreatment of the dependent person. Optimal psychosocial interventions to be assumed by European Governments in their long - term care systems are still needed to be developed to fight succesfully against this burden.The objective is to …
An overview of the service industries' future (priorities: linking past and future)
2011
The innovative future of service industries in detail from any viewpoint or theoretical perspective forms the central subject matter for this special issue. One of the sectors considered to be relevant for favouring the growth of the international economy is the services sector. The relative ease with which services can be implanted in certain activities with notably less capital than that required for most industries, as well as the direct and indirect effects it generates on the job market, are factors that have brought about belief and reliance on this sector to provide a means of growth and a way of recovering from any international economic crisis, and in the future may prove to play a…
Carbon and safe-haven flows
2022
<abstract> <p>This paper explores the role of European Union Allowances (EUAs) as a safe haven for a range of assets and analyses the effect of safe-haven flows on the European carbon futures market. In particular, we demonstrate that EUAs can be considered a refuge against fluctuations in corporate bonds, gold and volatility-related assets in periods of market turmoil. Furthermore, we have shown that extremely bearish and bullish movements in those assets for which the EUA acts as a safe haven induce excess volatility in carbon markets, higher carbon trading volume and larger than normal EUA bid-ask spreads. These findings support the idea that some traders, by considering carb…
EXTRACTION OF BIOLOGICALLY ACTIVE COMPONENTS FROM FRESHWATER SAPROPEL
2019
Sapropel has been used for different purposes - in agriculture as fertilizer, in construction as building material, in cosmetic products, in balneology also in medicine and pharmaceuticals as bioactive component. Previously sapropel has been commonly used in raw form and there is no general accepted method or standard method for obtaining sapropel extract. However, most extraction methods follow the same path. Currently, there are few extraction methods using several extractants for obtaining bioactive components from raw sapropel. The most commonly used extractant is alkaline solution. When sapropel is subjected to alkaline environment, the humic and fulvic acids, together with some lipids…
Chapter 2 Biosynthesis in Rauwolfia serpentina Modern Aspects of an Old Medicinal Plant
1995
Publisher Summary This chapter discusses a research on Rauwolfia , which was achieved after the generation of a cell suspension with extraordinary growth characteristics and physiological behavior. The investigations demonstrated that a range of techniques is now available for the clarification of complete metabolic pathways, provided that the appropriate efficient biological system is available. The isolation and identification of each single enzyme have almost become routine, even if an extremely sensitive protein analytic technique is necessary when several kilograms of fresh plant cells are reduced to a few micrograms of homogenous protein. The successful identification of a total of 20…
