Discrete stage-structured prey and prey-predator models are considered. Regarding the former, we prove that the models at hand are permanent (i.e., the population will neither go extinct nor exhibit explosive oscillations) and, moreover, that the transfer from stability to nonstationary behaviour always goes through a supercritical Neimark−Sacker bifurcation.The prey model covers species that ...

The present study sheds light on the kind of relationships that link first transaction consumer satisfaction (CS), purchase intention (PI), and willingness to pay (WTP) for new food products. The article presents a comparative evaluation of linear and nonlinear quadratic and cubic specifications used to assess the relationships involved. The study uses empirical evidence from three product-testing ...

Interpretive marine turtle tours in Cyprus yields an alluring ground to unfold the complex nature of pro-environmental behavior among travelers in nature-based destinations. Framing on Collins (2004) interaction ritual concept and the complexity theory, the current study proposes a configurational model and probes the interactional effect of visitors’ memorable experiences with environmental ...

We model bioeconomic interrelations between a commercial fishery and an aquaculture industry by using a dynamical systems theory approach. The biomass follows a logistic growth where the pollution emerging from aquaculture is accounted for by means of a retardation term. We investigate the existence and stability of the equilibrium states of this model as a function of the growth-retardation parameter ...

We analyze how backcountry skiers’ perceived ability to manage avalanche terrain correlate with more objective measures of experience and skills, among 1209 backcountry riders in Norway and North America. We further analyze if self-assessed backcountry skills are affected by past experience of avalanches and close calls, risk attitudes, and demographics. Our results suggest that self-assessed skill ...

The problem studied is related to new venture creation. The question the authors will examine here is: What are the knowledge conditions for new venture creation? The methodology used is conceptual generalization. The purpose of the paper is to bring new understandings to venture creation. In attempting to answer the research question, the authors hope to make a contribution to a policy for ...

The current paper contributes to signalling theory by demonstrating the importance of digital quality signals in influencing consumer preferences for sales and segmentation in the context of marketing fresh fish online. We conducted a choice-based conjoint analysis with a latent class segmentation to analyse the significance of digital quality signals compared to traditional attributes online. The ...

Aim: The prevalence of overweight and obesity has risen rapidly worldwide, and the ongoing obesity pandemic is one of the most severe public health concerns in modern society. The average body mass index (BMI) of people living in Northern Norway has also steadily increased since the late 1970s. This study aimed to understand how individuals’ health behavior is associated with the general health ...

Aquaculture (i.e., farming of aquatic organisms, including fish, molluscs, crustaceans, and aquatic plants) is playing an increasingly important role in the global food supply. The contribution of aquaculture to total fish production has risen steadily, reaching 44% in 2014 (Moffitt and Cajas-Cano, 2014). The future growth of aquaculture is expected to help accomplish the Sustainable Development ...

I artikkelen presenterer vi et konsept der en student løser tradisjonelle finansoppgaver i regneark i stedet for på papir. Oppgavene er interaktive. Dette betyr at studentene kan få formative tilbakemeldinger automatisk når de selv ønsker det. Målet med tilbakemeldingene er å hjelpe studentene til å komme et skritt videre med problemløsingen sin. Den innovative algoritmen som evaluerer studentenes ...
