LAS DISTINTAS PERSPECTIVAS DE TOMA DE DECISIONES EN EL PROCESO DE FORMACIÓN DE LA ESTRATEGIA Y EL MIDDLE MANAGEMENT ROLE
2010
<p>Este trabajo tiene como objetivo analizar los temas relacionados con las distintas perspectivas de toma de decisiones en la organización: top-down, bottom-up y middle-up-down y el papel del directivo medio en ese proceso. Para ello se busca delimitar los conceptos derivados de estudios empíricos e teóricos seminales, cruzando diferentes líneas de pensamiento, pretendiendo formar un marco teórico conceptual en torno a la perspectiva integradora en el proceso de formación de la estrategia. En cuanto a la forma de desarrollo del estudio, este se caracteriza como un ensayo teórico, al revisar estos conceptos y teorías de manera que del análisis se pueda obtener una propuesta de aplicac…
Heterogeneity in Disordered Gambling: Decision-Making and Impulsivity in Gamblers Grouped by Preferred Form
2019
Background: Previous research has indicated that disordered gamblers display deficits in impulsivity and risky decision-making, compared to healthy control groups. However, disordered gamblers are not a homogenous group, and differences in performance on neurocognitive tasks may be related to the form of gambling in which an individual chooses to engage. The present study used neurocognitive tasks and questionnaire measures to ascertain group differences in gamblers grouped by preferred form of gambling. Method: Treatment-seeking pathological gamblers from the National Problem Gambling Clinic, London (n = 101), completed a neurocognitive assessment comprising the Cambridge gamble task (CGT)…
Goals and guesses as reference points: a field experiment on student performance
2022
In this paper, we study overconfidence and goal-setting in academic performance, with and without monetary incentives. Students enrolled in a microeconomics course were offered the possibility of setting their own target grade before taking part in the final exam. They were also asked to guess their grade immediately after they had taken the exam (“post-diction”). In general, students overestimated their performance, both at the goal-setting and at the post-diction stages. Controlling for several sources of this bias (cognitive abilities, academic record and self-reported academic confidence), we find that the use of monetary rewards mitigates the overestimation of potential achievements an…

Processi di consultazione e partecipazione: un quadro generale
2009
L’analisi delle motivazioni che hanno portato, in più parti del mondo, ad avviare pratiche di consultazione parte da una constatazione condivisa da molti: la crisi della democrazia rappresentativa e il conseguente tentativo di rivitalizzarla, introducendo forme di democrazia deliberativa. Marilena Macaluso analizza questo ed altri elementi, come la sindrome NIMBY che blocca le grandi opere, e presenta modalità di consultazione diverse ma con un comune obiettivo: rilegittimare i processi decisionali, coinvolgendo i soggetti interessati, e, quindi, ricomporre il conflitto. Macaluso ci parla della consultazione supportata dalle nuove tecnologie; delle indicazioni di ONU, OCSE e UE in materia d…
El papel de la prensa en la educación científica y tecnológica
2015
En una sociedad como la actual, donde la ciencia y la tecnología impregnan el día a día, resulta esencial la formación de una ciudadanía con capacidad crítica para participar en la toma de decisiones sobre cuestiones relacionadas con la ciencia y la tecnología, de forma fundamentada. La necesidad de una alfabetización no solo científica, sino también mediática e informacional de la ciudadanía, unida al grave fracaso escolar y a la falta de interés por los estudios científicos, puesta de manifiesto reiteradamente por la investigación, requieren una actuación desde diferentes ámbitos (tanto desde la educación formal como de la no reglada), con propuestas y estrategias que contribuyan a una me…
Trygghet når du trenger det mest : en kvalitativ studie av intensivsykepleieres erfaringer med bruk av CAM-ICU.
2016
Masteroppgave i spesialsykepleie – Universitetet i Agder 2016 Background: 50-90 % of all patients whom is hospitalized in an ICU will suffer from intensive care delirium. The decision-making-tool CAM-ICU is used and activated in many of the intensive-care units in Norwegian hospitals. Some research show that the tool isn’t used correctly – therefor I wanted to find out what experience my fellow ICU-nurses had with the tool. Aim and objective: The aim of this study is to gain a broad understanding into the ICU-nurses experience, using CAM-ICU. Method: Seven qualitative semi-structured interviews were conducted by a total of eight ICU-nurses using CAM-ICU to identify and prevent delirium. The…
Evolution of impatience: The example of the Farmer-Sheriff game
2015
The literature on the evolution of impatience, focusing on one-person decision problems, often finds that evolutionary forces favor the more patient individuals. This paper shows that in games where equilibrium involves threat of punishment there are forces generating an evolutionary advantage to the impatient. In particular, it offers a two-population example where evolutionary forces favor impatience in one group while favoring patience in the other. Moreover, efficiency may also favor impatient individuals. In our example, it is efficient for one population to evolve impatience and for the other to develop patience. Yet, evolutionary forces move the opposite direction. Fil: Levine, David…
A Population-Based Approach to the Resource-Constrained Project Scheduling Problem
2004
We present a population-based approach to the RCPSP. The procedure has two phases. The first phase handles the initial construction of a population of schedules and these are then evolved until high quality solutions are obtained. The evolution of the population is driven by the alternative application of an efficient improving procedure for locally improving the use of resources, and a mechanism for combining schedules that blends scatter search and path relinking characteristics. The objective of the second phase is to explore in depth those vicinities near the high quality schedules. Computational experiments on the standard j120 set, generated using ProGen, show that our algorithm produ…
Expert system for predicting unstable angina based on Bayesian networks
2013
The use of computer-based clinical decision support (CDS) tools is growing significantly in recent years. These tools help reduce waiting lists, minimise patient risks and, at the same time, optimise the cost health resources. In this paper, we present a CDS application that predicts the probability of having unstable angina based on clinical data. Due to the characteristics of the variables (mostly binary) a Bayesian network model was chosen to support the system. Bayesian-network model was constructed using a population of 1164 patients, and subsequently was validated with a population of 103 patients. The validation results, with a negative predictive value (NPV) of 91%, demonstrate its …
