The scientific method and elements of bias are fundamentally at odds with one another. While the prior seeks to identify truth through objective analysis, the latter wishes to prove one's preconceptions through artificially created or filtered observations. Both the scientific method and bias are purpose-driven notions, both serve an intrinsic value. Arguably the more general and truly-lasting ...
The true MR signal intensity extracted from noisy MR magnitude images is biased with the Rician noise caused by noise rectification in the magnitude calculation for low intensity pixels. This noise is more problematic when a quantitative analysis is performed based on the magnitude images with low SNR(<3.0). In such cases, the received signal for both the real and imaginary components will fluc...
Objectives: The goal of the present study was to determine the prediction model of social phobia by investigating a number of its predictors. In this study shyness, behavioral inhibition, attentional bias, interpretation bias, social self-efficacy and attachment were assessed as predictors of social phobia. Method: 438 students of Tehran University participated in this study. All participants c...
Aims and background: Selective attention to pain-related stimuli, known as pain attentional bias (AB) can exacerbate pain, disability and undermine quality of life. The aim of this study was to determine effectiveness of mindfulness oriented recovery enhancement approach on attentional bias related to pain and disability among Chronic Pain Patients. Materials and methods: The present study was...
Williams, Watts, Macleod and Mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.Although this prediction has been supported by some researchers (Denny & Hunt, 1992 mathews, Moog, et al , 1989 watkins, et al, 1992), the reliability ...
Codon bias refers to the differences in the frequency of occurrence of synonymous codons in coding DNA. Pattern of codon and optimum codon utilization is significantly different between the lives. This difference is due to the long term function of natural selection and evolution process. Genetics drift, mutation and regulation of gene expression are the main reasons for codon bias. In this stu...
The one photon absorption (OPA) cross section of a current carrying two-orbital quantum dot (QD) with strong electron-phonon interaction (polaron regime) is considered. Using the self-consistent non-equilibrium Hartree-Fock (HF) approximation, we determine the dependence of OPA cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...
The field of cognitive psychology has increasingly provided scientific insights to explore how humans are subject to unconscious sources of evidentiary bias, leading to errors that can affect judgement and decision-making. Increasingly these insights are being applied outside the realm of individual decision-making to the collective arena of policy-making as well. A recent editorial in this jou...
سخن سردبیر editorial مجله دانشگاه علوم پزشکی رفسنجان دوره 14، مهر 1394، 534-533 راه حل های ارائه شده برای تورش انتشار the solutions offered for publication bias محسن رضائیان[1] m. rezaeian در سخن سردبیری شماره پیشین مجله دانشگاه به پدیده تورش انتشار پرداختیم و آن را به معنای انتشار بیشتر مقالاتی با نتیجه مثبت و یا نتیجه معنی دار آماری تعریف کردیم. همچنین، مختصری از تاریخچه بررسی تور...
Language technology is biased toward English newswire. In POS tagging, we get 97–98 words right out of a 100 in English newswire, but results drop to about 8 out of 10 when running the same technology on Twitter data. In dependency parsing, we are able to identify the syntactic head of 9 out of 10 words in English newswire, but only 6–7 out of 10 in tweets. Replace references to Twitter with re...
