Die Digitalisierung und der Wandel der Kundenbedürfnisse verändern das Nutzerverhalten sowie das Nutzenverständnis der Kunden und erfordern neue Wertangebote, also Produkte und Dienstleistungen, auch im B2B-Bereich. Deshalb werden bisher getrennte oder vollständig neue Wertangebote zunehmend in gemeinsamen Geschäftsmodellen von einer Gruppe interagierender Akteure innerhalb von sogenannten Business Ecosystems gebündelt. Die Relevanz dieses Sachverhalts und die einhergehende Veränderung der Kooperationsart und Interaktionsintensität zwischen den Unternehmen (Industrielogik) wurde in einer Studie mit 16 Maschinenbauunternehmen untersucht. Im ersten Teil des Beitrags, der in der wt Werkstattstechnik online Ausgabe 11/12-2019 erschienen ist, wurde die Ausgangssituation der Branche, der Stand der Forschung und die Zielsetzung der Studie beschrieben. In diesem zweiten Teil werden die wesentlichen Erkenntnisse der Studie diskutiert und ein zusammenfassender Ausblick gegeben.   Digitization and changes in customer needs affect both user behaviour and understanding and require new value propositions (products and services), also in the B2B sector. For this reason, previously separate or completely new value propositions are increasingly bundled in common business models by a group of interacting actors within so-called business ecosystems. The relevance of this issue and the associated change in the type of cooperation and interaction intensity between companies (industry logic) was investigated in a study with 16 mechanical engineering companies. In the first part of the article, in the wt Werkstattstechnik online issue 11/12 2019, the initial situation of the industry, the state of research and the objectives of the study were described. In this second part, the main findings of the study are discussed and a summarizing outlook is given.

Thymol (THY) was found to have in vitro antifungal activity against 24 fluconazole (FLC)-resistant and 12 FLC-susceptible clinical isolates of Candida albicans, standard strain ATCC 10231 and one experimentally induced FLC-resistant C. albicans S-1. In addition, synergism was observed for clinical isolates of C. albicans with combinations of THY–FLC and THY–amphotericin B (AMB) evaluated by the chequerboard microdilution method. The interaction intensity was determined by spectrophotometry for the chequerboard assay, and the nature of the interactions was assessed using two non-parametric approaches [fractional inhibitory concentration index (FICI) and ΔE models]. The interaction between THY–FLC or THY–AMB in FLC-resistant and -susceptible strains of C. albicans showed a high percentage of synergism by the FICI method and the ΔE method. The ΔE model gave results consistent with FICI, and no antagonistic action was observed in the strains tested.

<p>Online interaction is considered to be a key aspect of effective e-learning and improved academic achievement. However, few studies have examined how effectiveness varies with the degree of interaction intensity. Using data for 17,090 students from three Catalan universities, in this paper we study the productivity associated with five different levels of interaction intensity in learning. We also compare the results obtained for fully online education with those for face-to-face learning. The analyses show that interaction in online education has diminishing returns, while in face-to-face learning it does not do so in a pure way. These results have implications for determining the optimum level of interaction that should be sought when designing courses and educational policies.</p>

Mangroves in China are severely affected by the rapid invasion of the non-native species Spartina alterniflora . Although many studies have addressed the possible impacts of S. alterniflora on the performance of mangrove seedlings, how excessive nitrogen (N) input due to eutrophication affects the interactions between mangrove species and S. alterniflora remains unknown. Here, we report the results from a mesocosm experiment using seedlings of the native mangrove species Kandelia obovata and the exotic S. alterniflora grown in monoculture and mixed culture under no nitrogen addition and nitrogen (N) addition treatments for 18 months. Without N addition, the presence of S. alterniflora inhibited the growth of K. obovata seedlings. Excessive N addition significantly increased the growth rate of K. obovata in both cultures. However, the positive and significantly increasing relative interaction intensity index under excessive N input suggested that the invasion of S. alterniflora could favour the growth of K. obovata under eutrophication conditions. Our results imply that excessive N input in southeastern China can increase the competitive ability of mangrove seedlings against invasive S. alterniflora .
