Does uncertainty cause inertia in decision making? An experimental study of the role of regret aversion and indecisiveness

Previous research has shown that often there is clear inertia in individual decision making---that is, a tendency for decision makers to choose a status quo option. I conduct a laboratory experiment to investigate two potential determinants of inertia in uncertain environments: (i) regret aversion and (ii) ambiguity-driven indecisiveness. I use a between-subjects design with varying conditions to identify the effects of these two mechanisms on choice behavior. In each condition, participants choose between two simple real gambles, one of which is the status quo option. I find that inertia is quite large and that both mechanisms are equally important.

A utilidade das disciplinas na perspectiva dos alunos: estudo exploratório por questionário

RESUMO: Algumas investigações têm apontado que a “motivação dos alunos” influencia a participação e os resultados escolares, destacando-se de um conjunto de outras variáveis. A declaração de Utilidade das disciplinas, atribuída pelos alunos, poderá ser um dos construtos de “motivação” determinantes no “gosto pelas actividades lectivas”, influenciando, hipoteticamente, o empenho na aprendizagem e, a partir daí, os resultados escolares dos alunos. Argumentou-se, nos 3 estudos aqui apresentados, as relações da atribuição de Utilidade das Disciplinas, incluindo a perspectiva do tempo futuro, com o Gosto pelas disciplinas, o empenho na aprendizagem e os resultados dos alunos. De forma a verificar, perante este enquadramento, onde se destacam a Teoria de Expectiva-Valor, o conceito de Perspectiva de Tempo Futuro associado ao conceito de Instrumentalidade, e hipóteses, foi elaborado e aplicado um questionário. Na análise aos questionários realçamos que foi verificado uma tendência para atribuir pelo menos uma disciplina como a que os alunos mais gostam e mais útil consideram; uma justificação com motivos relacionados com a sua perspectiva de vida futura à disciplina que indicam como a mais útil e resultados médios altos a essas mesmas disciplinas. ABSTRACT: Some studies have pointed out that the "motivation of the students’ participation and influence on educational attainment, highlighting a number of other variables. The declaration of Utility of disciplines, awarded by students, may be one of the constructs of "motivation" in determining taste for teaching activities, influencing, hypothetically, the commitment to learning and, thereafter, the students’ school results. It was argued in three studies presented here, the relations of the allocation of Utility of disciplines, including the prospect of future time, with the taste for discipline, the commitment to learning and student outcomes. In order to asses this framework, where we highlight the expectancy-value theory, the concept of Future Time Perspective associated with the concept of Instrumentality, and hypotheses, a questionnaire was designed and applied. In the analysis the questionnaires highlight a trend that was to assign at least one discipline as the students like best and more useful view, a justification with reasons related to their future life prospects which indicate the discipline as the most useful and results medium high on those subjects.

Sintomas depressivos e ansiosos em mães de recém-nascidos com e sem malformações

OBJETIVO: comparar as condições emocionais de mães cujos filhos nascem com malformações visíveis (Grupo M) com as das mães de crianças eutróficas (Grupo E) logo após o nascimento. MÉTODO: foram avaliados os sintomas de ansiedade e depressão de 22 mães de cada grupo por meio do Inventário de Depressão de Beck (BDI) e do Inventário de Ansiedade Traço-Estado (IDATE). Foram excluídas as mães portadoras de deficiência sensorial incapacitante, HIV, distúrbios psiquiátricos e síndromes genéticas. Os dados foram complementados com consultas a prontuários médicos da criança e da mãe. Para análise comparativa entre as medianas dos grupos foi utilizado o teste não-paramétrico U de Mann-Whitney; para amostras independentes e para os escores indicativos de sintomas clínicos, o teste exato de Fisher e o teste do χ2. RESULTADOS: houve diferenças significativas nas medianas dos escores das três subescalas (ansiedade-traço, ansiedade-estado e disforia/depressão) entre os dois grupos de mães. Houve uma porcentagem significativamente maior de mães do Grupo M com escores indicativos de sinais clínicos para depressão ou ansiedade no pós-parto imediato e, para ambos os quadros, quando comparadas com mães do Grupo E. Os resultados podem ser decorrentes de traços de personalidade materna, visto que os índices de ansiedade-traço eram significativamente maiores nas mães de crianças malformadas, mas especialmente pelo estado da criança, seu encaminhamento para a UTI e sua condição de vida futura. CONCLUSÕES: a porcentagem de mães de recém-nascidos com malformações visíveis que apresentou escores indicativos de sinais clínicos para ansiedade, depressão e ambos sugerem a necessidade de suporte, individual ou em grupo.

[Killing and dignity of animals: a problem for veterinarians?]

Killing of animals is an important task to be performed by veterinarians. Killing decisions and their implementation often raise ethical questions. As a result of an interdisciplinary workshop targeting the subject "killing of animals" with veterinarians and ethicists, a three-dimensional dimension scheme was developed. Whereas the first two dimensions are focused on the animal's past and future life and are discussed with regard to life quality and life accomplishment (the "telos"), the third dimension incorporates the reason to kill and may integrate the concept of dignity. This form of dignity and the weighing of interests are applied to example scenarios and the resulting responsibilities of veterinarians and society are discussed.

Transport of Hydraulic Fracturing Water and Wastes in the Susquehanna River Basin, Pennsylvania

The development of the Marcellus Shale gas play in Pennsylvania and the northeastern United States has resulted in significant amounts of water and wastes transported by truck over roadways. This study used geographic information systems (GIS) to quantify truck travel distances via both the preferred routes (minimum distance while also favoring higher-order roads) as well as, where available, the likely actual distances for freshwater and waste transport between pertinent locations (e. g., gas wells, treatment facilities, freshwater sources). Results show that truck travel distances in the Susquehanna River Basin are greater than those used in prior life-cycle assessments of tight shale gas. When compared to likely actual transport distances, if policies were instituted to constrain truck travel to the closest destination and higher-order roads, transport mileage reductions of 40-80% could be realized. Using reasonable assumptions of current practices, greenhouse gas (GHG) emissions associated with water and waste hauling were calculated to be 70-157 MT CO2 eq per gas well. Furthermore, empty so-called backhaul trips, such as to freshwater withdrawal sites or returning from deep well injection sites, were found to increase emissions by an additional 30%, underscoring the importance of including return trips in the analysis. The results should inform future life-cycle assessments of tight shale gases in managed watersheds and help local and regional governments plan for impacts of transportation on local infrastructure.

Exculpating victims and the reversal of hindsight bias

This experiment examines the role of the hindsight bias and of motivational forces such as the motive to believe in a just world as possible causes of the derogation of victims effect in the context of rape. The hindsight bias is the tendency of people to falsely believe that they would have predicted the outcome of an event once the outcome is known. Participants read descriptions of an interaction between a man and a woman that ended with one of four possible outcomes: The woman was raped with very severe consequences for her future life vs. rape with only minor consequences for her future life vs. no rape (assailant was forced to retreat by the strong defense of the victim) vs. no outcome information. To test motivational predictions the hindsight bias and the derogation effect were analyzed as a consequence of the sex of participants, the seriousness of the consequences of the rape, the belief in a just world and the acceptance of rape myths. Results supported the assumption that derogation effects are at least partly driven by hindsight bias and that motivational processes work via the hindsight bias. However, in this study we did not find a classical hindsight bias but a reversed hindsight bias: Especially female participants in the severe consequences of rape condition and those participants who did not accept rape myths rated the likelihood of rape in the rape outcome condition as smaller than participants in the no outcome information control group. They also derogated the victim less than participants in the no information control group. These effects were interpreted in terms of self-serving or in-group serving functions of the hindsight bias. Finally no support was found for the assumption that derogation effects are driven by the motive to believe in a just world.

La significación ontológico-existencial del tiempo en Gabriel Marcel

Gabriel Marcel entiende que el tiempo no puede considerarse como un dato objetivo solamente, sino que tiene su sentido primordial en su carácter vivido. Así, el tiempo se comprende desde el registro del presente, con su tensión de pasado y futuro. La vida misma supone una cierta interpretación del tiempo vivido, articulándola a partir de acontecimientos vitales centrales en la propia vida y orientada a una trascendencia que la signifique. Pero es en las experiencias cúlmenes de la vida humana, como el sacrificio, la fidelidad, la esperanza y la fe que el tiempo roza la eternidad, entendida como plenitud de lo vivido.

Zum Einfluss vorschulischer Kinderbetreuung auf den Bildungsweg und den erwarteten Erfolg am Arbeitsmarkt

In dem Beitrag wird der Frage nachgegangen, welchen Einfluss die Inanspruchnahme frühkindlicher Bildungs- und Betreuungsangebote auf den späteren Schulbesuch von Kindern hat und wie sich dies längerfristig auf die zu erwartenden Lebenseinkommen und damit einhergehend den langfristigen volkswirtschaftlichen Nutzen auswirkt. Untersucht werden Kinder in Deutschland der Jahrgänge 1990 bis 1995. Die Datengrundlage liefert das Sozio-oekonomische Panel (SOEP). Der Schwerpunkt der Analysen liegt auf der Bestimmung des Effekts des Krippenbesuchs auf die spätere Einstufung in die verschiedenen Schultypen in Abhängigkeit der sozialen Herkunft und des Migrationshintergrunds der Kinder. Ausgehend von diesen Schätzungen werden dann die zu erwartenden, über den Bildungsabschluss vermittelten Auswirkungen des Krippenbesuchs auf das spätere Lebenseinkommen bestimmt, um einen Eindruck der langfristigen volkswirtschaftlichen Folgen vorschulischer Kinderbetreuung zu erhalten. Der Beitrag zeigt, dass der Krippenbesuch die Wahrscheinlichkeit einer Einstufung ins Gymnasium nach Kontrolle relevanter Drittvariablen im Schnitt um rund 14 Prozentpunkte erhöht. Dieser Einfluss entspricht einem erwarteten Lebenseinkommenszuwachs von rund 27000 Euro. Wird dieser Ertrag auf den Zeitpunkt des Krippenbesuchs abdiskontiert und den Kosten eines durchschnittlichen Krippenbesuchs in der Höhe von rund 8000 Euro gegenübergestellt, so ergibt sich ein Kosten-Nutzen-Verhältnis von 1 zu 2.7.
