Pushing Through or Slacking Off? Heterogeneity in the Reaction to Rank Feedback

2018

This paper studies heterogeneity in the reaction to rank feedback. In a laboratory experiment, individuals take part in a series of dynamic real-effort contests with intermediate feedback. To solve the identification problem in estimating the causal effect of rank feedback on subsequent effort provision we implement a random multiplier in the first round of each contest. The realization of this multiplier then serves as a valid instrument for rank feedback. While rank feedback has a robust effect on subsequent effort provision on average, an explicit analysis of between-subject heterogeneity reveals that a substantial fraction of participants in fact react entirely opposite than the aggrega…

Parents' causal attributions concerning their children's academic achievement

2007

Katja Natale seurasi väitöstutkimuksessaan vanhempien lastensa koulumenestystä koskevien kausaaliattribuutioiden eli syyselitysten muotoutumista lasten siirtyessä esikoulusta kouluun. Hän tutki kuinka tärkeinä vanhemmat pitivät kykyä, yrityksen määrää, tehtävien vaikeustasoa ja lapsen saamaa ohjausta selittämässä lasten onnistumista ja epäonnistumista koulussa. - Koulunsa aloittavien lasten vanhempia voisi neuvoa viestimään lapsilleen, että heillä on kykyjä onnistua haastavissakin koulutehtävissä. Tällainen viesti vaikuttaa positiivisesti lasten koulutaitojen kehitykseen ja minäkuvan muuttumiseen realistisemmaksi, Natale suosittaa.Onnistuminen kyvykkyyttä, epäonnistuminen yrityksen puutetta…

Una revisión del concepto de «acumulación por desposesión» de D. Harvey

2019

espanolEl objetivo del presente articulo sera realizar una revision critica de la interpretacion realizada por D. Harvey del concepto de «acumulacion originaria» expuesto por K. Marx en El Capital. A traves del analisis de los escritos donde Marx aborda esta cuestion, trataremos de demostrar que la aportacion principal de Harvey -reinterpretar la acumulacion originaria, no como proceso fundacional de las condiciones necesarias para la produccion capitalista, sino como proceso continuo y permanente utilizado para restablecer las condiciones optimas de la acumulacion de capital mediante la conquista de nuevos espacios- se sustenta en una interpretacion parcial de los textos de critica de la e…

Bovine spongiform encephalopathy and Creutzfeldt-Jakob disease: facts and uncertainties underlying the causal link between animal and human diseases

2004

Following an outbreak of bovine spongiform encephalopathy (BSE) in dairy cows in the United Kingdom (UK), 153 definite and probable human cases of new variant Creutzfeldt-Jakob disease (nvCJD) have been reported, almost exclusively in the UK. Although exposure to the BSE agent is the most plausible interpretation for the occurrence of nvCJD, the causal link between the BSE prion and nvCJD is still debated. This review discusses the pros and cons of nvCJD as a separate nosographic entity, the scientific basis for a correlation between BSE and nvCJD, the validity of the current diagnostic criteria for CJD and nvCJD, the contribution of epidemiology to the detection of a causal relation betwee…

Relationship between Helicobacter pylori infection and GERD

2018

Gastroesophageal reflux disease (GERD) is due to the chronic exposure of the esophageal mucosa to acid secretion from the stomach. Helicobacter pylori (H.p.) infection, is a risk factor for the development of peptic ulcer, atrophic gastritis and gastric cancer, and causes various effects on gastric function. The relationship between GERD and H.pylori infection is still subject of debate.Background and aim: In literature no clear causal relationship has been established between GERD and H. pylori infection, although some papers support the onset of esophagitis in patients in whom the infection has been cured. Aim of this work is to review the most recent literature data about the relationshi…

Aquatic ecotoxicology: On the problems of extrapolation from laboratory experiments with individuals and populations to community effects in the field

1991

Abstract 1. 1. Ecotoxicology is defined as the study of the effect of toxicants on structure and function of ecosystems. 2. 2. Properties of individuals and populations in laboratory experiments differ from those in the field with respect to distribution in space and time as well as to genetic structure. 3. 3. Studies of community response can only be extrapolated to other systems if they include the analysis of the causal chain. 4. 4. Causal explanations require a system analysis at different trophic levels as well as a modelling of the system and an analysis of sensitivity. 5. 5. A research project is presented which covers most of the suggested problems.

Pseudomonas aeruginosa cause epidemic disease in the milkweed bug,Oncopeltus fasciatus dallas (Insecta, Heteroptera)

1976

Pseudomonas aeruginosa was recognized as the causative organism of an epidemic disease occurring in a laboratory breed ofOncopeltus fasciatus. The infection probably occurs peroral and is favoured by high temperature and humidity.Pseudomonas aeruginosa destroys the fat body of the bug.
