Wiberg, Karin. "Political bias in hiring : people consider political opponents as less hireable than others without weighting criteria to justify why." Thesis, Högskolan Kristianstad, Fakulteten för lärarutbildning, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:hkr:diva-19437.

Abstract (sommario):

Previous studies have shown that characteristics like gender and ethnicity can affect the possibility to be hired. Decisions in hiring may also be justified by weighting the importance of hiring criteria and can thus seem unbiased. In other areas, bias due to political affiliation have been noted to be even more pronounced than bias due to ethnicity. However, effects of candidates’ political affiliation in hiring are not equally researched. This study aimed to fill this blank. Participants (N= 283) were randomized to a between-subjects design; A third read a resumé from a candidate affiliating

Abstract (sommario):

Background: Empirical studies in psychiatric research and other fields often show substantially high refusal and drop-out rates. Non-participation and drop-out may introduce a bias whose magnitude depends on how strongly its determinants are related to the respective parameter of interest. Methods: When most information is missing, the standard approach is to estimate each respondent’s probability of participating and assign each respondent a weight that is inversely proportional to this probability. This paper contains a review of the major ideas and principles regarding the computation of s

Abstract (sommario):

When measuring market risk, credit institutions and Alternative Investment Fund Managers may deviate from equally weighting historical data in their Value-at-Risk calculation and instead use an exponential time series weighting. The use of expo-nential weighting in the Value-at-Risk calculation is very popular because it takes into account changes in market volatility (immediately) and can therefore quickly adapt to VaR. In less volatile market phases, this leads to a reduction in VaR and thus to lower own funds requirements for credit institutions. However, in the ex-ponential weighting a hig

Abstract (sommario):

<p>This thesis addresses the issue of weighted cost-benefit analysis (WCBA). WCBA is a welfare evaluation model where income distribution effects are valued by distributional weighting. The method was developed already in the 1970s. The interest in and applications of this method have increased in the past decade, e.g. when evaluating of global environmental problems. There are, however, still unsolved problems regarding the application of this method. One such issue is the choice of the approach to the means of estimating of the distributional weights. The literature on WCBA suggests a couple

Abstract (sommario):

Within our research group Bayesian Risk Solutions we have coined the idea of a Bayesian Risk Management (BRM). It claims (1) a more transparent and diligent data analysis as well as (2)an open-minded incorporation of human expertise in risk management. In this dissertation we formulize a framework for BRM based on the two pillars Hardcore-Bayesianism (HCB) and Softcore-Bayesianism (SCB) providing solutions for the claims above. For data analysis we favor Bayesian statistics with its Markov Chain Monte Carlo (MCMC) simulation algorithm. It provides a full illustration of data-induced uncertaint

Abstract (sommario):

The importance of sound financial risk management has become increasingly emphasised in recent years, especially with the financial crisis of 2007-08. The Basel Committee sets the international standards and regulations for banks and financial institutions, and in particular under market risk, they prescribe the internal application of the measure Value-at-Risk. However, the most established non-parametric Value-at-Risk model, historical simulation, has been criticised for some of its unrealistic assumptions. This thesis investigates alternative approaches for estimating non-parametric Value-a

Dans les modèles de régression, les réponses manquantes limitent notre capacité à faire des inférences sur les effets des covariables décrivant la distribution de la totalité des réponses prévues sur laquelle porte l'intérêt médical. Outre la perte de précision, toute inférence statistique requière qu'une hypothèse sur le mécanisme de manquement soit vérifiée. Rubin (1976, Biometrika, 63:581-592) a appelé le mécanisme de manquement MAR (pour les sigles en anglais de « manquant au hasard ») si la probabilité qu'une réponse soit m

At the same time, due to the channel and noise effect, equalized signal suffers the magnitude and phase degradation. Therefore, we propose a novel concept which is to consider the magnitude and phase degradation of equalized signal in Viterbi algorithm. The CSI is obtained from the weighting values of one-tap frequency domain LMS equalizers on different subcarriers. Comparing to conventional OFDM receiver structure, because we use the different rel
