CYGD: the Comprehensive Yeast Genome Database.
2005
The comprehensive resource is available under http://mips.gsf.de/genre/proj/yeast/.; International audience; The Comprehensive Yeast Genome Database (CYGD) compiles a comprehensive data resource for information on the cellular functions of the yeast Saccharomyces cerevisiae and related species, chosen as the best understood model organism for eukaryotes. The database serves as a common resource generated by a European consortium, going beyond the provision of sequence information and functional annotations on individual genes and proteins. In addition, it provides information on the physical and functional interactions among proteins as well as other genetic elements. These cellular network…
Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.
2015
Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…
Vegetation Patterns in the Hyperbolic Klausmeier Model with Secondary Seed Dispersal
2023
This work focuses on the dynamics of vegetation stripes in sloped semi-arid environments in the presence of secondary seed dispersal and inertial effects. To this aim, a hyperbolic generalization of the Klausmeier model that encloses the advective downhill transport of plant biomass is taken into account. Analytical investigations were performed to deduce the wave and Turing instability loci at which oscillatory and stationary vegetation patterns arise, respectively. Additional information on the possibility of predicting a null-migrating behavior was extracted with suitable approximations of the dispersion relation. Numerical simulations were also carried out to corroborate theoretical pre…
Gestural expressions in use for unveiling dynamic experience attributed to verbs
2013
The focus of this paper is on justifying the presented experimental design that aims at examining the enactive linkages between a verb’s content and a sensorimotor experience of movement. The experiment utilised spontaneous production of hand and vocal gestures for expressing the energetic feel attributed to a word. Preliminary qualitative analysis of the expressions shows degrees of similarity in terms of experiential movement qualities. These results imply that conceiving a verb’s meaning is not necessarily far removed from bodily action. peerReviewed
The effects of two-way communication and chat service usage on consumer attitudes in the e-commerce retailing sector
2018
In e-commerce retailing (e-retailing), where competitors are only one click away and prices are easy to compare, providing superior customer service and reciprocal communication via a company’s website are important aspects of attracting and retaining customers. One increasingly popular solution to improve customer service is a “live chat” interface that allows consumers to have real-time conversations online with customer service agents. As the literature on the impacts of real-time communication via live chat is currently very limited, this study develops and tests a model that demonstrates the moderating effects of a chat service on the relationship between two-way communication (i.e., a…
Interaction in online learning environments : how to support collaborative activities in higher education settings
2006
Collaboration promoted and supported by instructional technology has the potential to lead learners to deeper understanding and knowledge building. There have been optimistic views that any web based interaction can be educationally valuable. However, online learning environments do not, as such, guarantee that learners will achieve genuine collaboration. It seems that there are several difficulties facing those who wish to employ online learning environments as a medium for productive learner interaction. The particular aim of this exploration of interaction and learning in computer supported collaborative learning environments was to study the interplay between learners and consider the w…

Applying Affordances Scale as a Design Method : Case Virtual Reality Course Design
2021
Practitioners including designers and teachers developing Virtual Reality (VR) courses are facing a question regarding the strengths and subject areas in which VR-enriched courses might have the highest potential compared to conventional courses. The present study develops a survey scale to assess and match industry managers’ requirements for skills for working life. The same scale was surveyed among two different groups of higher education students participating in conventional courses and a VR-aided course. The results indicate that the industry requirements were higher than met by the both course types. However, the results highlight a set of skills for which the VR courses have the high…
Online support for vulnerable consumers: a safe place?
2017
Purpose This paper aims to examine the service experience in an online support community of consumers to understand the nature of social support and how it is experienced and enacted by vulnerable consumers. Design/methodology/approach A netnographic study was conducted to examine vulnerable consumers’ participation in an online support group for weight management. The Linguistic Inquiry Word Count (LIWC) program was used, and additionally data were coded using open coding. A hybrid approach to data analysis was undertaken using inductive and deductive methods. Findings The findings suggest online social support groups can be used as an online “third place” to support vulnerable consumers, …
Digital Activism in Russia: The Evolution and Forms of Online Participation in an Authoritarian State
2020
AbstractThis chapter describes how digitalization has affected activism in Russia by tracing the evolution, particularity, and the most visible forms of online activism in the context of the increasingly authoritarian Russian state. It discusses online activism in relation to “connective action” and illustrates it with two examples of contentious political activism: the anti-corruption campaign led by Alexei Navalny and the struggle to protect online communication from state surveillance by the Telegram messenger service. In addition, the chapter presents examples of Russian activism, which do not directly challenge the Kremlin.
