The role of models in management and conservation of weeds
2013
Session 7 - Options and perspectives in weed managementEASPEEcolDurCT1; Weeds are both a harmful crop pest and an important component of biodiversity. Moreover, herbicide use must be reduced to limit its impact on environment, and weed control must now combine numerous management techniques with partial efficiency aiming at preventing weed occurrence. Biological regulations of weeds by other biotic components could also contribute to control infestations. Thus, new cropping systems are needed, combining numerous techniques and aiming at both maximising weed-related biodiversity and minimising weed harmfulness.[br/]Weed dynamics models are increasingly used to design innovative cropping syst…
ELECTRE III and IV Decision Aids in an Environmental Problem
1997
This paper gives a description and analysis of the use of ELECTRE III and IV decision aids in the context of choosing a solid waste management system in two different real applications in Finland. Both methods fit this context well in general, since the problem involves many criteria and many ‘decision makers’. The available data are imprecise, which also favours the use of outranking methods. In addition to the real applications, we also study the choice behaviour offered for decision makers in connection with these methods by looking at some test results obtained from randomly generated problems. In general, the results of ELECTRE III and IV do not differ substantially from those from the…
Cardiac Troponins for the Diagnosis of Acute Myocardial Infarction in Chronic Kidney Disease
2018
Background Patients with chronic kidney disease ( CKD ) are at high risk of myocardial infarction. Cardiac troponins are the biomarkers of choice for the diagnosis of acute myocardial infarction ( AMI ) without ST ‐segment elevation ( NSTE ). In patients with CKD , troponin levels are often chronically elevated, which reduces their diagnostic utility when NSTE ‐ AMI is suspected. The aim of this study was to derive a diagnostic algorithm for serial troponin measurements in patients with CKD and suspected NSTE ‐ AMI . Methods and Results Two cohorts, 1494 patients from a prospective cohort study with high‐sensitivity troponin I (hs‐ cTnI ) measurements and 7059 cases from a clinical registr…
Interactive Decision Aids
2011
Decision support systems assist people in making a decision or choosing a course of action in a nonroutine situation that requires judgment (Haubl and Trifts 2000; Kasper 1996). In online webstores, vendors can easily offer highly interactive types of decision support. These co-called interactive decision aids (IDA) “help consumers in making informed purchase decisions amidst the vast availability of online product offerings” (Wang and Benbasat 2009, p. 3). However, the application of IDA is not restricted to purchase decisions. They are general enough to be of use in any kind of choice task where alternatives are known.
Perceptual commensuration in decision tables
2017
This paper calls attention to design features that could enhance the helpfulness of the decision table to decision makers trying to get a better intuitive grasp of the choices facing them. The experiments reported here show that the grey scale is more facilitative than the number scale for problem comprehension as measured by the identification of dominance and the identification of non-additivity, each of which requires a view of the decision problem that is sensitive to patterns across attributes. Additional design features that could enhance the decision makers’ grasp of the choices facing them are suggested for further research.
Utility of Alternative Effect Size Statistics and the Development of a Web-Based Calculator: Shiny-AESC
2018
Alternative displays of effect size statistics can enhance the understandability and impact of validity evidence in a variety of applied settings. Arguably, the proliferation of alternative effect size statistics has been limited due to the lack of user-friendly tools to create them. Common statistical packages do not readily produce these alternative effect sizes and existing tools are outdated and inaccessible. In this paper, I introduce a free-to-use web-based calculator (https://dczhang.shinyapps.io/expectancyApp/) for generating alternative effect size displays from empirical data. This calculator requires no mathematical or programming expertise, and therefore, is ideal for academics …
