Opis:
Attentional bias is assumed to be partly responsible for the onset and maintenance of anxiety by major cognitive theories of emotional disorders. Although much is already known about the therapeutic effects of attentional bias training, only a few studies have examined the mechanism responsible for these effects. In order to test if low-level, cognitive effects of attentional bias training depend on attentional control, 73 participants, who completed the STAI-x2 and the ACS questionnaires, were randomly assigned to a control (n = 37) or attentional training group (n = 36). The attentional manipulation was followed by a search task, during which novel neutral or negative faces could be presented within an array of all-neutral, all-negative or all-positive faces. It was found that individuals with higher ACS score displayed stronger attentional training effects, i.e., they were less accurate in detecting distinctive negative faces, and this effect was not found to be associated with STAI-x2 score. These results show that there is individual variability even in immediate, cognitive effects of attentional bias modifi cation and that special abilities, such as attentional control, might be required for attentional training to be effi cient.

Opis:
According to major cognitive theories of emotional disorders cognitive biases are partly responsible for their onset and maintenance. The direct test of this assumption is possible only if experimental method capable of altering a given form of cognitive bias is available. The purpose of the study was to examine the effectiveness of a novel implicit memory bias training procedure based on the emotional version of the classical Sternberg’s short-term memory task with negative, neutral and positive words. 108 participants, who completed the PANAS and the CES-D questionnaires, were randomly assigned to the control group (n = 33), the No-Negative group (n = 36), in which the target words in the Sternberg’s task were either positive or neutral but never negative or the Negative-New group (n = 39) in which the negative target words in the modified Sternberg’s task were always new. This training was followed by the recollection stage. Only one of the training protocols resulted in significant effects at the recall stage - individuals in the No-Negative group recalled more positive words and fewer negative words than those in the control group. These results show that it may be possible to experimentally induce memory bias characteristic of non-depressed individuals.

Opis:
The Colombian Observatory of Science and Technology -OCyT- developed, in 2009, a survey about understanding of Science and Technology in students of high school in Bogotá, Colombia. The sampling design was stratified according to the nature of school (public or private). Two sources of unit nonresponse were detected. The first one corresponds to schools that did not allowed to collect information. The second source corresponds to students who did not assist during the days when survey was applied. Estimates were obtained through two different approaches. Results obtained in both cases do not show visible differences when estimating ratios; even though, some great differences were observed when estimating totals. Results obtained using the second approach are believed to be more reliable because of the methodology used to handle item nonresponse.

Opis:
Previous studies (Bocian & Wojciszke, 2014) showed that self-interest biases moral perception of others’ unethical actions. Moreover, affective changes in attitudinal responses towards the perpetrator of an immoral act drives the bias. In the present studies, we attempted to answer the question whether people are aware of the self-interest bias in their judgments of others’ behavior. We conducted two experiments showing that moral judgments of verbally described and imagined actions were dominated by norms rather than self-interest (Study 1) and that people were not aware that self-interest distorted their moral judgment (Study 2). The unawareness of the self-interest bias among the participants was attributable to omission of their own emotional responses when forecasting their moral judgments. We discuss the importance of emotions presence in studies on moral judgments as well as contribution of the present research to the intuitionist approach to moral judgment.

Opis:
Digital elevation models (DEM), including the Shuttle Radar Topography Mission (SRTM), are used in many branches of geoscience as an ultimate dataset representing our planet’s surface, making it possible to investigate processes that are shaping our world. The SRTM model exhibits elevation bias or systematic error over forests and vegetated areas due to the microwaves’ peculiar properties that penetrate the vegetation layer to a certain depth. Numerous investigations identified that the penetration depth depends on the forest density and height. In this contribution, two methods are proposed to remove the impact of the vegetation impenetrability effect. The first method is founded on the multiple regression of two forest characteristics, namely forest height and forest density. The second method uses a lookup table approach. The lookup table and the multiple regression explanatory variables are taken from the freely available datasets, including the forest density data (MODIS_VCF) and global tree height map (GTHM). An important role in this research is played by the Ice, Clouds, and Land Elevation Satellite (ICESat) data. The accuracy tests indicate that the first method eliminates approximately 68% of the elevation bias, while the second method appears to be more effective, leading to almost complete removal of the vegetation bias from the SRTM data. The methods are fine-tuned to the local coniferous forests in Poland. Additional studies are required to finetune the methods for the leaf-off state of deciduous forests. However, a new set of parameters for both methods can be quickly developed for different locations and forest types. Both methods’ functionality and effectiveness can be improved once more accurate forest tree height and vegetation density data become available. These methods are universal in mitigating the vegetation bias from the Synthetic Aperture Radar Interferometry (InSAR) derived model and photogrammetric models.

Opis:
The paper proposes summarized attribution-based post-hoc explanations for the detection and identification of bias in data. A global explanation is proposed, and a step-by-step framework on how to detect and test bias is introduced. Since removing unwanted bias is often a complicated and tremendous task, it is automatically inserted, instead. Then, the bias is evaluated with the proposed counterfactual approach. The obtained results are validated on a sample skin lesion dataset. Using the proposed method, a number of possible bias-causing artifacts are successfully identified and confirmed in dermoscopy images. In particular, it is confirmed that black frames have a strong influence on Convolutional Neural Network’s prediction: 22% of them changed the prediction from benign to malignant.

Opis:
In a laboratory experiment, I examined two behavioural effects: hypothetical bias and the framing effect. I elicited willingness to pay (WTP) for a cosmetic product, and manipulated framing conditions (positive vs. negative attribute framing) and incentives to reveal the actual valuation (hypothetical vs. real). I demonstrated that hypothetical bias has a significant impact on WTP values; however, the framing effect has no effect on the valuation of the product. Similarly, I found no interaction between the two effects. This observation contributes to claims that hypothetical research methods lead to equally reliable data as those based on consequential choices.

Opis:
Cytochrome b is the central catalytic subunit of the quinol:cytochrome c oxidoreductase of complex III of the mitochondrial oxidative phosphorylation system and is essential to the viability of most eukaryotic cells. Partial cytochrome b gene sequences of 14 species representing mammals, birds, reptiles and amphibians are presented here including some species typical for Poland. For the analysed species a comparative analysis of the natural variation in the gene was performed. This information has been used to discuss some aspects of gene sequence - protein function relationships. Review of relevant literature indicates that similar comparisons have been made only for basic mammalian species. Moreover, there is little information about the Polish-specific species. We observed that there is a strong non-random distribution of nucleotides in the cytochrome b sequence in all tested species with the highest differences at the third codon position. This is also the codon position of the strongest compositional bias. Some tested species, representing distant systematic groups, showed unique base composition differing from the others. The quail, frog, python and elk prefer C over A in the light DNA strand. Species belonging to the artiodactyls stand out from the remaining ones and contain fewer pyrimidines. The observed overall rate of amino acid identity is about 61%. The region covering Qo center as well as histidines 82 and 96 (heme ligands) are totally conserved in all tested species. Additionally, the applied method and the sequences can also be used for diagnostic species identification by veterinary and conservation agencies.

Opis:
Research has shown that cheating is perceived as immoral when it serves the cheater’s interests, though it can be seen as moral when it serves the interests of the perceiver. However, are such biased moral judgments real, or are they merely lip service? To answer the question of whether biased moral judgments actually inform behavior, the authors asked participants to observe a confederate who either cheated for money or did not cheat, which benefited either the confederate alone or both the confederate and the participating observer. Then, participants evaluated the confederate and, finally, played a one shot trust game with her. Cheating influenced moral judgments and decreased behavioral trust, but this only occurred when self-interest was not involved. When self-interest was involved, participants showed no significant differences in trust levels, independent of whether the confederate had cheated or not. Implications for the dual process theory in moral psychology are discussed.

Opis:
The paper deals with the problem of bias randomization in evaluation of the measuring instrument capability. The bias plays a significant role in assessment of the measuring instrument quality. Because the measurement uncertainty is a comfortable parameter for evaluation in metrology, the bias may be treated as a component of the uncertainty associated with the measuring instrument. The basic method for calculation of the uncertainty in modern metrology is propagation of distributions. Any component of the uncertainty budget should be expressed as a distribution. Usually, in the case of a systematic effect being a bias, the rectangular distribution is assumed. In the paper an alternative randomization method using the Flatten-Gaussian distribution is proposed.

The usual mean estimator, classical ratio, and regression estimators suggested by Naik and Gupta (1996) and Abd-Elfattah et al. (2010) estimators are identified as the members of the suggested class of estimators. The expressions of bias and mean square errors are derived up to first-order approximation. The proposed estimators were put to test against various other competing estimators till date. It has been found both theoretically and empirically that the suggested classes of estimators dominate the existing estimators.

Opis:
The 2014–2015 electoral cycle was a serious marketing challenge for Polish weeklies because of the gradual change in the balance of power (after several years of Civic Platform domination, the ratings of Law and Justice significantly improved), which implied a more leveled electoral rivalry and changes on the publishing market- leading to more intensive competition between weeklies presenting similar editorial perspective: “Polityka” – “Newsweek” – “W Sieci” – “Do Rzeczy” – “Gazeta Polska”, taking into consideration the relatively low number of readers of such publications. From this perspective the analysis of journalistic endeavors of “Polityka” during the period of time preceding the key elections (Presidential and Parliamentary) in 2015 seem to be an important research problem – taking into account the rank of “Polityka” and its part in forming and defining questions of civil and political discourse.

Opis:
Politics is a particular field of social activity where accusing an opponent of mental incapacitation occurs as a frequent element of the conducted narrative. Moreover, public opinion discrediting a profession of a politician is very eager to question the mental health of political actors. Vocabulary used in the public is a vital testimony of societies attitude towards people with mental disorders. However, we refer paranoia to personality traits of individuals while political paranoia refers to reaction to events, facts or to the way it is seen by individuals or groups. The authors do not have any ambition to carry out a psychological analysis of politicians. What is intriguing is the issue of using political paranoia (searching for enemies, tracking plots, fighting in defence of ideals, irrational justification of failures) in the group spectrum for elections. What is also intriguing is the answer to the question whether politicians are paranoid, or it is a well-planned election strategy which aims to identify an opponent to consolidate a group of voters around the leader.
