An Approach to the Automatic Comparison of Reference Point-Based Interactive Methods for Multiobjective Optimization
2021
Solving multiobjective optimization problems means finding the best balance among multiple conflicting objectives. This needs preference information from a decision maker who is a domain expert. In interactive methods, the decision maker takes part in an iterative process to learn about the interdependencies and can adjust the preferences. We address the need to compare different interactive multiobjective optimization methods, which is essential when selecting the most suited method for solving a particular problem. We concentrate on a class of interactive methods where a decision maker expresses preference information as reference points, i.e., desirable objective function values. Compari…
Shall we follow? Impact of reputation concern on information security managers’ investment decisions
2020
Information security (infosec) is important for organizations. While budgeting for infosec is a crucial resource allocation decision, infosec managers may choose to follow other fellow experts’ recommendations or baseline practices. The present paper uses reputational herding theory to explain the decision made by infosec managers to use a “let's follow others” strategy in this context. Based on a sample of 106 organizations in Finland, we find that infosec managers’ ability to accurately predict the benefit of infosec investment, as well as their reputations, have significant effects on motivating them to discount their own information. Infosec managers’ discounting of their own informatio…
Interactivized : Visual Interaction for Better Decisions with Interactive Multiobjective Optimization
2022
In today’s data-driven world, decision makers are facing many conflicting objectives. Since there is usually no solution that optimizes all objectives simultaneously, the aim is to identify a solution with acceptable trade-offs. Interactive multiobjective optimization methods are iterative processes in which a human decision maker repeatedly provides one’s preferences to request computing new solutions and compares them. With these methods, the decision maker can learn about the problem and its limitations. However, advanced optimization software usually offer simple visualization tools that can be significantly improved. On the other hand, current approaches for multiobjective optimization…
Psychomotor speed in a random sample of 7,979 subjects aged 30 years and over.
2011
Background and aims: Slowing of psychomotor speed among older individuals has been shown in numerous studies. However, in most cases these studies were based on small and selected groups of people and, in some cases, the test procedures did not allow separation of decision time and motor components of the overall performance. The purpose of the present study was to analyse in a large, randomly selected population sample the differences in decision and movement times in simple and multiple-choice test conditions. The association of educational background with psychomotor speed was also examined. Methods: Data on psychomotor speed were collected from a representative nation-wide sample of the…
Preference for place of death in Germany.
2011
Dying in the preferred place is considered a key requirement for a "good death." The aims of our study were to explore preferred places of death of deceased people and their bereaved relatives in Rhineland-Palatinate (Germany). We further wanted to assess the congruence between preferred and actual place of death.The cross-sectional study was based on a random sample of 5000 inhabitants of Rhineland-Palatinate (Germany) who died between May 25 and August 24, 2008. Relatives of these deceased persons were interviewed by a written survey.After removing duplicates, 4967 questionnaires were sent out, 3832 delivered, and 1378 completed, yielding a response rate of 36.0%. Regarding the deceased, …
Roles Of Stakeholders In Strategic Decision-Making Of Microfinance Organizations
2010
Microfinance organizations provide financial services to low income people. These organizations have been increasing dramatically worldwide. This increment calls attention for these organizations and their boards to make strategic decisions which enable them perform well and compete with each other. Based on literature, this paper identifies six types of microfinance stakeholders who sit on boards. These are clients, employees, government, donors, creditors and owners. This paper discusses the different roles of these stakeholders when they sit on boards of microfinance organizations and these roles are further explained to show how they contribute to the process of making strategic decisio…
Akute Lungenembolie – Eine kritische Übersicht über aktuelle Leitlinien und Empfehlungen
2013
Die akute Lungenembolie (LE) ist eine haufige und potenziell lebensbedrohliche Erkrankung. Dieser Artikel bietet eine kritische Ubersicht uber die aktuellen Leitlinien und Empfehlungen fur das Management der akuten LE. Die Symptome und klinischen Zeichen sind unspezifisch und umfassen Dyspnoe, Brustschmerzen, Hamoptyse, Synkope, arterielle Hypotension und Schock. Bei Patienten mit klinischem Verdacht auf akute LE sollte umgehend das Vorliegen eines hohen Risikos aufgrund hamodynamischer Instabilitat festgestellt oder ausgeschlossen werden. Dies wird ein risikoadaptiertes diagnostisches und therapeutisches Vorgehen ermoglichen. Nach Semiquantifizierung der klinischen Wahrscheinlichkeit einer…
Modelling Electricity Price Expectations in a Day-Ahead Market: A Case of Latvia
2016
Abstract The paper aims at modelling the electricity generator’s expectations about price development in the Latvian day-ahead electricity market. Correlation and sensitivity analysis methods are used to identify the key determinants of electricity price expectations. A neural network approach is employed to model electricity price expectations. The research results demonstrate that electricity price expectations depend on the historical electricity prices. The price a day ago is the key determinant of price expectations and the importance of the lagged prices reduces as the time backwards lengthens. Nine models of electricity price expectations are prepared for different natural seasons an…
Understanding frailty:a qualitative study of European healthcare policy-makers' approaches to frailty screening and management
2018
ObjectiveTo elicit European healthcare policy-makers’ views, understanding and attitudes about the implementation of frailty screening and management strategies and responses to stakeholders’ views.DesignThematic analysis of semistructured qualitative interviews.SettingEuropean healthcare policy departments.ParticipantsSeven European healthcare policy-makers representing the European Union (n=2), UK (n=2), Italy (n=1), Spain (n=1) and Poland (n=1). Participants were sourced through professional networks and the European Commission Authentication Service website and were required to be in an active healthcare policy or decision-making role.ResultsSeven themes were identified.

Physiotherapists' lived experiences of decision making in therapeutic encounters with persons suffering from whiplash-associated disorder: A hermeneu…
2020
Conceptual discussions related to clinical reasoning and decision making have evolved over the years from biomedical to incorporating more holistic approach to reasoning. Empirical studies exploring clinical reasoning and decision making in physiotherapy practice have mostly focused on aspects of managing persons with low back pain, such as exercise prescription, education and communicating diagnosis. There is a paucity of studies exploring decision making in whiplash‐associated disorder (WAD); thus, the aim of this study was to explore the physiotherapists' lived experiences of decision making related to treating persons with WAD. A qualitative research design based on hermeneutic phenomen…
