Multiple modalities in insect warning displays have additive effects against wild avian predators
2019
Allocation to different components of defence has been suggested as an explanation for the existence of multiple aposematic morphs in a single population. We tested whether there are trade-offs between warning colouration and chemical defence or whether these have an additive effect when combined, using blue tits (Cyanistes caeruleus) as predators and the polymorphic wood tiger moth (Arctia plantaginis) as prey. We used artificial edible models (with and without the moths’ defensive fluids) with paper wings whose colour and pattern properties matched those of real moths. When the models were presented sans defensive fluids or when the fluids were presented without colour cues, we detected n…
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…
Environmental remediation using nanomaterial as adsorbents for emerging micropollutants
2023
Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
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…
Examining the antecedents and consequences of perceived value : a case study of mobile banking application usage in the Kingdom of Saudi Arabia
2022
Recent advancements in information, communications, and mobile technologies have revolutionized banking and payment services as well as consumer behavior. This study examines the continuous usage experience of mobile financial services, and especially mobile banking services, in the Kingdom of Saudi Arabia (KSA), the context of this study. Data were collected from 300 experienced mobile banking users across the KSA using a pre-tested survey instrument. The partial least squares structural equation modelling (PLS-SEM) was used to analyze the data. The results supported most of the hypotheses and revealed that e-service quality, e-information quality, and experience flow have a significant an…
Collaboration network for inspiring children and youth into science, mathematics and technology in Finland
2021
The importance of STEM education is widely recognized. Despite the value of the sector and good associated employment prospects, young students generally lack interest in science and engineering. This is reflected in the difficulty universities experience in recruiting qualified students for STEM subjects, which in turn is reflected in business life and is a factor slowing down countries’ economic development. In Finland, efforts have been made to solve this challenge by launching the LUMA Centre Finland network, which consists of 13 university-related centres promoting STEM issues throughout Finland. This paper describes the network and its objectives, with a special focus on the activitie…

Mobility of Cultures and Knowledge Management in Contemporary Europe
2012
In the aftermath of the fall of the Iron Curtain, the European Union (EU) has included more and more new member states from Central and Eastern parts of the European continent. This enlargement process has increased the cultural diversity of the European community as new languages and minority groups have been subsumed into the EU. It is the purpose of this article to discuss the challenges that result from the EU's enlargement, together with the added intra-European mobility of cultures, that affect the national knowledge infrastructures. Based on recent social scientific scholarship on mobility and cultures, this article proposes that knowledge management in contemporary Europe is not onl…
Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?
2022
Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…
