Plant growth can be limited by resource acquisition and defence against consumers, leading to contrasting trade-off possibilities. The competition-defence hypothesis posits a trade-off between competitive ability and defence against enemies (e.g. herbivores and pathogens). The growth-defence hypothesis suggests that strong competitors for nutrients are also defended against enemies, at a cost t...
The Effect of Online Privacy Information on Privacy Evaluations in Using Mobile Fitness Applications
This paper proposes an investigation on the effect of online privacy information on privacy evaluation in using mobile fitness applications. Drawing on the justice framework, we identify three key types of annotated privacy information, namely social rating, profile control, and security conformity, to be particularly important to users’ transactional privacy trade-off in evaluating mobile fitn...
The competition-colonization trade-off has long been a mechanism explaining patterns of species coexistence and diversity in nonequilibrium systems. It forms one explanation of the intermediate disturbance hypothesis (IDH) for local communities--specifically that diversity should be maximized at intermediate disturbance frequencies, yet only a fraction of empirical studies support IDH predictio...
Life-history theory posits a fundamental trade-off between number and size of offspring that structures the variability in parental investment across and within species. We investigate this 'quantity-quality' trade-off across primates and present evidence that a similar trade-off is also found across natural-fertility human societies. Restating the classic Smith-Fretwell model in terms of allom...
Trade-offs play pivotal roles in the ecology and evolution of natural populations. However, trade-offs are probably not static, invariant relationships. Instead, ecological factors can shift, alter, or reverse the relationships underlying trade-offs and create critical genotype x environment (G x E) interactions. But which ecological factors alter trade-offs or create G x E interactions, and wh...
40 For decisions made under time pressure, effective decision making based on 41 uncertain or ambiguous evidence requires efficient accumulation of evidence 42 over time, as well as appropriately balancing speed and accuracy, known as the 43 speed/accuracy trade-off. For simple unimodal stimuli, previous studies have 44 shown that human subjects set their speed/accuracy trade-off to maximize 45...
Trade-offs among life-history traits are often thought to constrain the evolution of populations. Here we report the disappearance of a trade-off between early fecundity on the one hand, and late-life fecundity, starvation resistance, and longevity on the other, over 10 yr of laboratory selection for late-life reproduction. Whereas the selected populations showed an initial depression in early-...
We used experimental evolution to test directly the important and commonplace evolutionary hypothesis that adaptation, increased fitness within the selective environment, is accompanied by trade-off, a loss of fitness in other nonselective environments. Specifically, we determined whether trade-offs at high temperature generally and necessarily accompany genetic adaptation to low temperature. W...
In this paper, the error-reject trade-off of linearly combined multiple classifiers is analysed in the framework of the minimum risk theory. Theoretical analysis described in [12,13] is extended for handling reject option and the optimality of the error-reject trade-off is analysed under the assumption of independence among the errors of the individual classifiers. Improvements of the error-rej...
This paper explores the factors that influence capital structure decisions in South Africa from the perspective of the Chief Financial Officer (CFO). The results of a survey of 33 CFOs of JSE listed companies find that South African CFOs are equally likely to follow the Pecking Order or Static Trade-Off theories. However, smaller companies are more likely to follow the Pecking Order theory whil...
