The Regret and Disappointment Scale: An instrument for assessing regret and disappointment in decision making

AbstractThe present article investigates the effectiveness of methods traditionally used to distinguish between the emotions of regret and disappointment and presents a new method — the Regret and Disappointment Scale (RDS) — for assessing the two emotions in decision making research. The validity of the RDS was tested in three studies. Study 1 used two scenarios, one prototypical of regret and the other of disappointment, to test and compare traditional methods ("How much regret do you feel" and "How much disappointment do you feel") with the RDS. Results showed that only the RDS clearly differentiated between the constructs of regret and disappointment. Study 2 confirmed the validity of the RDS in a real-life scenario, in which both feelings of regret and disappointment could be experienced. Study 2 also demonstrated that the RDS can discriminate between regret and disappointment with results similar to those obtained by using a context-specific scale. Study 3 showed the advantages of the RDS over the traditional methods in gambling situations commonly used in decision making research, and provided evidence for the convergent validity of the RDS

Assessment of Operators' Workload, Visual Attention, and Satisfaction in an Upgraded Control Room After Changes of Work Procedures

The adoption of new equipment in a work environment is usually meant to improve technology, increase safety and strengthen environmental protection. At the same time, however, technological changes can influence workers’ performance, thus workload and tasks’ reallocation should always be evaluated whenever new equipment is introduced. The aim of this study was to evaluate the effects on operators’ workload of new procedures adopted in a Marine Terminal Control Room following recommendations provided in a previous study (Plet, Gerbino, Tognolli, & Marcatto, 2013). Moreover, operators’ acceptance and satisfaction of the new procedures were assessed. Results show that the new procedures have improved work performance leaving the overall subjective workload unchanged at a medium-low level

Look ma(rket), No Hands! Optimism Bias and Illusion of Control in Finance Professionals

The optimism bias is the tendency to judge one’s own risk as less than the risk of others. In the present study we found that also finance professionals (N = 60) displayed an optimism bias when forecasting the return of an investment made by themselves or by a colleague of the same expertise. Using a multidimensional approach to the assessment of risk perception, we found that participants’ forecasts were biased not because they judged negative consequences as less likely for themselves, but because they were overconfident in their ability to avoid and control them

Dimensionamento de um flutuante de concreto armado atravéz de um software de análise pelo método dos elementos finitos

TCC (graduação) - Universidade Federal de Santa Catarina, Campus Joinville, Engenharia Civil de Infraestrutura.Estruturas de concreto armado são amplamente utilizadas nas mais diferentes estruturas, e diversas metodologias de projeto são desenvolvidas para calcular tais estruturas corretamente. Nesse contexto, o presente trabalho aborda fundamentos gerais da análise e dimensionamento estrutural de flutuantes de concreto armado. Inicialmente explana-se sobre os conceitos básicos relativos ao tema estudado através de revisão bibliográfica e são expostas as teorias fundamentais sobre os elementos de concreto armado, as formas de aplicação das forças atuantes e a metodologia de cálculo para o dimensionamento estrutural. Como foco principal, este estudo baseou-se na metodologia de cálculo pelo Método dos Elementos Finitos (MEF) e critérios estabelecidos pela Associação Brasileira de Normas Técnicas pelas normas NBR 6118 (2014) e NBR 9782 (1987). Posteriormente, foi possível realizar o estudo de caso do projeto de um flutuante de concreto armado executado na cidade de Paranaguá-PR. Foram realizadas análises e comparações entre o projeto executado e o projeto desenvolvido com base na metodologia descrita neste trabalho. Para isso, foi estudado e utilizado o software de análise estrutural SAP2000, baseado no Método dos Elementos Finitos, sendo possível comparar entre as soluções adotadas para o projeto estrutural executado e do modelo proposto para o flutuante. A partir dos resultados obtidos, infere-se que o procedimento de dimensionamento de flutuantes descrita neste trabalho pode ser uma alternativa adequada e mais eficiente e econômica, pois resultou em um dimensionamento mais detalhado e com uma menor quantidade de aço.Reinforced concrete structures are widely used in many different types of structures, and in many project methodologies are developed to calculate those structures correctly.

The perceived stress-at-work scale

Psychometric instruments designed to assess work-related stress at the organizational level, such as the HSE-MS Indicator Tool, are usually very effective at identifying the domains of work design that, if not properly managed, can expose workers to high stress risk. These instruments, however, usually lack a measure of workers\u2019 perception of stress at work, which could be useful for identifying the organizational dimensions more associated with workrelated stress. The aim of the present study was to investigate the psychometric properties of a new short scale for assessing workers\u2019 perception of stress at work, which could be used along with organizational level questionnaires. The perceived stress-at-work scale is composed of 4 items assessing perception of job strain, pressure and agitation, and health concerns due to work. A sample of public sector employees (N = 883) received a booklet containing the ERI-Q (long version, [1]), the HSE-MS Indicator Tool (Italian version, [2,3]), the Satisfaction with Life Scale [4] and the new 4-item perceived stress-at-work scale. Results showed good reliability of the perceived stress-at-work scale (Cronbach\u2019s alpha = .80) and strong correlations with two concurrent measures, the ERI-Q imbalance score (r = .63, p < .001) and the ERI-Q overcommitment scale (r = .52, p < .001). Next, structural equation modeling was used to investigate the relationships among organizational risk factors, measured by the HSE-MS Indicator Tool, perceived stress at work, and workers\u2019 life satisfaction. Three organizational dimensions, namely demand, relationships, and role, resulted to be significantly associated with perceived stress at work, explaining about 45% of its variance. Moreover, the effect organizational risk factors on workers\u2019 life satisfaction turned out to be mediated by workers\u2019 perception of stress at work. The new perceived stress-at-work scale resulted to be a valid and reliable instrument, displaying good internal consistency and strong correlations with other individual-level measures of work strain. Furthermore, the scale could be used to highlight the critical intervention targets for risk stress management strategies, when applied along with an organizational level questionnaire such as the HSE-MS Indicator Tool

Good advice is rarer than rubies: A study on online Tripadvisor hotel reviews

User-generated content websites, such as review sites or travel communities, have become a major source of information for travelers with the advent of Web 2.0. A recent study [1] showed that more than 40% of travelers use the reviews and comments of other consumers as information sources when planning trips. While many studies have investigated the use and influence of online reviews on consumers, less is known about what motivates travelers to write online reviews. According to the results of the Yoo & Gretze's survey [2], based on a panel of TripAdvisor reviewers, the motivation to write online travel reviews is accounted for by four dimensions: Enjoyment/positive self- enhancement, Venting negative feelings, Concerns for other consumers, and Helping the company. As a consequence, the motivation to review should be high after extremely good outcomes (due to enjoyment in sharing a good experience, helping the company that provided a good travel service) and extremely bad experiences (owing to engagement in negative word-of-mouth to warn others, see also [3]), and low after intermediate/neutral experiences. In this study we adopted a data-driven approach in order to test the empirical robustness of such an expectation. Specifically, we investigated the motivation to write online travel reviews, by analyzing a publicly available world-wide dataset of 246,399 user generated hotel reviews posted on TripAdvisor [4]. Following on the expectation rising from the four dimension model of motivation proposed by [2], if reviewers are highly motivated to write after extremely good and extremely bad experiences, the distribution of overall hotel ratings (ranging from 1 \u201cbubble\u201d, labeled as \u201cterrible\u201d, to 5 \u201cbubbles\u201d, labeled as \u201cexcellent\u201d) should be expected to be U-shaped, with central ratings being less represented than extreme values (1 \u201cbubble\u201d and 5 \u201cbubbles\u201d). The empirical distribution of ratings showed instead that the most represented ratings were 5 and 4 \u201cbubbles\u201d (accounting for 75% of all ratings), thus reflecting the fact that the majority of reviewers judged their experience in a monotonic continuum from very good to excellent. The same pattern of results emerged also in sub- ratings (business service \u2013 63%, cleanliness \u2013 81%, front desk \u2013 75%, location \u2013 84%, rooms \u2013 73%, service \u2013 75%, and value \u2013 73%). The monotonic pattern of responses revealed by our study demonstrated that engaging in negative word-of-mouth to vent negative feelings and to warn others may not be an important motivation for writing online reviews. We speculate that monotonicity could results from a positivity bias in remembering and evaluating hedonic experiences [5].
