Nutritional quality of littoral macroinvertebrates and pelagic zooplankton in subarctic lakes
2021
Littoral benthic primary production is considered the most important energy source of consumers in subarctic lakes. We analyzed essential fatty acid (EFA) and amino acid (EAA) content of 23 littoral benthic macroinvertebrate taxa as well as cladocerans and copepods from pelagic and littoral habitats of 8–9 subarctic lakes to compare their nutritional quality. Pelagic crustacean zooplankton had significantly higher EFA and total FA content (on average 2.6‐fold and 1.6‐fold, respectively) than littoral macroinvertebrates in all our study lakes. Specifically, docosahexaenoic acid (DHA), one of the most important EFA for juvenile fish, was almost exclusively found in pelagic copepods. In littor…
Prioritisation of alternatives with analytical hierarchy process plus response latency and web surveys
2014
This paper introduces a new method that combines the well-known analytical hierarchy process (AHP) with a response latency metric. The response latency is the time taken by respondents to make choices over pairwise comparisons. The analytical calculation of relative importance weights of the alternatives is made by using a response latency model previously validated in several case studies. This combination aims to overcome some drawbacks of the traditional AHP related to the use of a rating scale (the so-called Saaty scale), and it is a natural way to involve response latency in established decisionmaking methods. This new method can be profitably adopted in web surveys where it is easy to…
Prioritization of Alternatives with AHP Plus Response Latency and Web Surveys
2013
Purpose: Overcome some drawbacks of the widely applied Analytical Hierarchy Process (AHP) related to the use of a rating scale for respondent’s judgments and propose a new method to prioritize alternatives based on web surveys. Methodology/Approach: We use the response latency, i.e. the time taken to make a decision, to replace the rating scale in the pairwise comparisons which is a fundamental part of the AHP procedure. A method combining the AHP with a mathematical model for the response latency is proposed in the paper. Findings: Eliminating the rating scale and leaving only the “take the best” task alleviates the respondent and makes the survey much faster and intuitive. Moreover the re…
