While the Food and Biotechnology industries often use unit operations that have been known for some time, sometimes these processes are not efficient or sustainable. The need to develop more efficient processing lines to obtain higher quality products is of utmost importance. Over the last years, pulsed electric fields (PEF) processing has attracted the interest of numerous researchers and companies due to its ability to reduce processing time, preserve thermolabile compounds, which are responsible for the aroma, nutritional and bioactive properties of food products.
Therefore, in this article, some of the most important studies regarding the application of PEF technology in food and biotechnology processing is discussed.
Germany is Europe’s most populated country and it is actual locomotive for growth. The Germans have a positive image in China. However, this appreciation is not mutual. Various polls indicate that Germans are reserved concerning China’s rise; some even dislike outward foreign direct investment (OFDI) from Chinese Companies flowing to Germany. Nevertheless, Chinese investments in Germany will accelerate in the near future; already it increased from 600 million € 2 years ago to more than 800 million €. Experts predict a further massive increase. Asian OFDIs in Europe will be an integral part of the Asian Century, transforming the host countries, just as western OFDIs changed Asia during the last decades. This article analyses the German “China readiness” in the field of public economic policy at a local level.
This research project focused on the consumers' acceptance of a newly developed apple in order to encourage the purchase behavior in the supermarket. It was enriched with selenium via biofortification in order to address the undersupply with the trace element in the German population. The study included online surveys and a market test in food retail. The results were used as preparation for the design of a marketable apple product. In the online pretest, the most popular apple cultivars, the most popular health benefits of selenium, as well as the respondents' preferences for the name of the new apple: Selstar® were detected. These results were included in an online survey which encompassed n=1042 interviews from German households. The sample was recruited according to national representative distribution of age groups, gender, and regions. The results show that the majority of the respondents were not sure what exactly selenium is and what it is used or needed for. Therefore, the product package included information about the health benefits of selenium, for e.g. the immune system. The stepwise approach of the research and the implementation of the results helped the targeted navigation of the market launch of the Selstar®.
In this paper we want to review and discuss research on the effects of occupational health management activities and services on different outcomes like employee health and well-being or absenteeism and other economic outcomes. In part I we outline goals and functions of occupational health management (OHM), then characterize typical occupational health promotion interventions and describe principles for implementing and organizing OHM. Part II focuses on different OHM activities and services such as creating healthy and safe workplace, reducing work-family conflicts, providing counselling via employee assistance programs and implementing health circles or stress management interventions. We will also discuss intervention design and sample studies as well as meta-analytic data relating to the effectiveness of these interventions. Finally, part III is about the economic impact of OHM. Findings from a management evaluation approach for OHM will be discussed. Then we will concentrate especially on data linking health promotion interventions to absenteeism and financial outcomes expressed as cost savings or cost-benefit ratios. The concluding part summarizes key findings of this paper.

This chapter reviews organizational development (OD) as networked man-agerial practices and investigates the role these practices play in contemporary strategic management and in management communication. Our analytical overview of studies finds that the literature lacks empirical evidence on the linguistic properties of OD’s practices as these properties have not been researched in OD but in settings where change is solely approached as a planned process. To fill this gap, we propose a research framework to inquire into OD’s verbal, paraverbal, and nonverbal practices. After a tour d’horizon of OD’s and change management’s ontological and epistemological paradigms, we outline the implications of the practice perspective of OD for strategic management, then narrow our focus to empirical studies’ prominent out-comes on discursive practices in change processes, and conclude with a framework for future research
Shockwaves are mechanical pressure pulses generated in liquids and gases. Based on the principles of acoustics, shockwavescan propagate through fluids such as water. At interfaces of materials with different acoustic impedances, mechanical energy is dissipated, and disintegration of biological tissue can be achieved. Physical properties as well as technical requirements for shockwave generation by electrohydraulic, electromagnetic or piezoelectric energy conversion have been reported in the literature. The use of electrohydraulic shockwaves for food treatment is an emerging food processing technology, where a lack of scientific and technical knowledge has limited further advancements in process and equipment design. In scientific literature, single aspects required for process description are available, e.g., in metallurgy, mining, air purification or particle accelerators, but their combination toward a combined model is required to characterize underlying mechanisms of action. In food, most of the studies have focused on shockwave technology for treatment of meat cuts with the purpose of reducing aging time, softening of tissue and improving its tenderness. Other applications of the shockwave technology could expand to biological inactivation, targeted texture modifications and improving extractive and refining processes in agriculture industries. Total processing costs are estimated in a range of a few Euros per ton of product. Despite being a promising alternative to existing processes used for these purposes, the application of shockwave in the food industry is limited to date to research on pilot-scale prototypes.
Health Telematics Europe
(2011)
The adoption and use of information technology (IT) in health care is influenced by many factors and depends on legal and cultural constraints prevailing in a country. While Europe is constantly coalescing on a political basis, health care is a sector still dominated by national legislation. Consequently, different types of national health care systems have existed throughout Europe for decades which now build the framework for the use of information and communication technology (ICT) by health care provider organizations. The following paragraphs will, therefore, provide a concise overview of the different types of national health care systems in Europe and will characterize the countries with regard to key indicators.

Olive oil holds significant importance in the European diet and is renowned globally for its sensory attributes and health benefits. The effectiveness of producing olive oil is greatly influenced by factors like the maturity and type of olives used, as well as the milling techniques employed. Generally, mechanical methods can extract approximately 80% of the oil contained in the olives. The rest 20% of the oil remains in the olive waste generated at the end of the process. Additionally, significant amounts of bioactive compounds like polyphenols are also lost in the olive pomace. Traditionally, heat treatment, enzymes, and other chemicals are used for the enhancement of oil extraction; however, this approach may impact the quality of olive oil. Therefore, new technology, such as pulsed electric field (PEF), is of great benefit for nonthermal yield and quality improvements.
This chapter presents the mechanism of the enhancement of freezing by means of ultrasound (US). It has been demonstrated that the effects of US are a rather complex issue. In theory, ultrasound creates cavitation bubbles throughout the volume of the product, which promotes nucleation of the ice and crushes the crystals already present in food. They can also enhance convective heat transfer to the cooling media, thereby accelerating freezing. Moreover, it has been shown that ultrasound reduces the degree of supercooling before nucleation in frozen food. Additionally, numerous experimental studies indicate that ultrasound assisted freezing is a good method to achieve homogenous crystallizations, reduce the deteriorating effect of freezing on food, and thus improve quality after thawing.
In this paper, we introduce a framework to identify domain specific use cases for smart glasses in the domain of logistics services. We further present and evaluate our framework through its application in a single case study in a wholesale warehouse. We contribute to theory and practice by presenting an approach to identify, define and describe application scenarios for the adoption of smart glasses in the logistics domain, and by enriching the current body of knowledge on digitalization, service support systems and wearables. Therefore, our research falls into line with the second topic. We directly address current challenges in logistics, one of Germany’s major economic sectors, regarding the implementation of new or advanced services with smart glasses. The presented case study is embedded in the digitalization project Glasshouse. The processes of two logistics services providers are the main research subjects in this project. In contrast to this, we focus on a third logistic service provider in this paper, to evaluate the transferability of our findings.
