AbstractThe response time concealed information test (RT-CIT) can reveal that a person recognizes a relevant item (probe) among other, irrelevant items, based on slower responding to the probe compared to the irrelevant items. Thereby, if this person is concealing knowledge about the relevance of this item (e.g., recognizing it as a murder weapon), this deception can be unveiled. In the present paper, we examined the impact of a speed versus accuracy instruction: Examinees (N = 235) were either presented with instructions emphasizing a focus on speed, with instructions emphasizing a focus on accuracy, or with no particular speed or accuracy instructions at all. We found that although participants responded to the probe and the irrelevants marginally faster when they had received instructions emphasizing speed, there was no significant difference between RTs of the different experimental groups and crucially no significant difference between the probe–irrelevant RT differences either. This means that such instructions are unlikely to benefit the RT-CIT, but it also suggests that related deliberate manipulation (focusing on speed on or accuracy) is unlikely to decrease the efficiency of the RT-CIT—contributing further evidence to the RT-CIT’s resistance to faking.

The response time‐based concealed information test can reveal when a person recognizes a relevant item among other, irrelevant items, based on comparatively slower responding. Thereby, if a person is concealing the knowledge about the relevance of this item (e.g., recognizing it as a murder weapon), this deception can be revealed. A recent study, conducted online and using a between‐subject design, introduced a significantly enhanced version by including additional items in the task. While this modified version outperformed the original version, it also resulted in a much higher rate of participant dropouts (i.e., participants leaving the experiment's website without completing the task). The grave implication is that the perceived enhancement is perhaps merely due to selective attrition. Therefore, the current experiment replicates the original one, but using a within‐subject design. The results show that there is a large enhancement even when selective attrition is prevented.

Abstract. Most psychometric tests assessing sustained attention are characterized by a specific presentation mode: Many items are presented simultaneously and the test takers are required to constantly process and react to them until the testing time is up. The aim of the present study was to look into two mechanisms that potentially underlie performance in these tests: The ability to focus on the currently relevant item and the ability to preprocess upcoming items to prepare for upcoming actions. In order to assess both abilities, the d2-R test of sustained attention was modified and its stimulus arrangement (single, blocks vs. rows of stimuli) was manipulated. The measure of focusing was unreliable and unrelated to performance in standard sustained attention tests. However, the data indicated a strong preview benefit. That is, the test takers preprocessed upcoming items when they got a valid preview of them, which considerably enhanced performance. Moreover, interindividual differences in the preview benefit proved to be internally reliable as well as reliable in retest and were substantially related to performance in three conventional sustained attention tests. We conclude that preprocessing constitutes an important component of performance in sustained attention tests and most likely represents a stable cognitive ability rather than a strategy.


Utility-mining is the present developing discipline of information-mining. Utility-mining combines different structures such as High relevant item-set mining, Relevant successive item-set mining, Negative relevant item-set mining, Uncommon high relevant item-set mining and so forth. Each procedure of these item-sets mining doesn’t acknowledge length of item-sets. An ongoing improvement in the field of Utility-mining is high normal utility item-set mining. The normal Utility-mining deals with length of item- sets alongside the utility of item-sets. Here few calculations are introduced to recover high average relevant item-sets present in the database. Primary target of the present work was to look at the three High Normal Utility Models calculations:1)High Normal Utility Models (HAUP) calculation, 2)High Normal Utility Item-Set-Excavator (HAUI-Miner) Calculation and 3)Productive High Normal Utility Pattern-Mining (EHAUPM) calculation. The execution-time and memory-space are examined as achievement measures for correlation. The EHAUPM calculation is more efficient compared to other calculations; this is discovered from the performed analysis.

Online education continues to increase. With increased online offerings, it is important to evaluate the integrity or equivalence of online/hybrid courses relative to face-to-face (F2F) courses. This study used three separate samples of business undergraduates taking both online/hybrid and F2F courses in the same semester (i.e., mixed course delivery format), across summer, fall and spring semesters. Eight items were used to assess students’ perceived favorability of online courses (PFoOC) compared to F2F courses. Across all three samples, two related but distinct sources for course comparison consistently emerged, instructor-related and peer related. An eight-item measure represents a necessary improvement over a previously developed four-item PFoOC measure, because it allows for additional relevant item comparisons between online/hybrid versus F2F courses. It is hoped that this measure can be used to further research evaluating online education.

ABSTRACTIn the last decades, Feminist Gender Studies have raised the invisibility of women as well as the later recognition of feminine specificity. The main european and american universities have considered disability process from the occidental culture, which is jointly affected. The observance of the women with disabilities circunstances is a relevant item, whereas women have been central subject in the Gender Studies analysis. This article describes the different gender theories contributions and recognizes a variety of publications and its relevance. Current contribution tries to come close to the reflection on difference´s women with disabilities.RESUMENEn las últimas décadas, se viene abordando, en el marco de los Estudios de Género, la invisibilidad de las mujeres como grupo y de forma vinculada, el posterior reconocimiento de la diferencia femenina. Se ha estudiado el proceso de discapacitación que ha afectado a las mujeres de forma colectiva. A este respecto, resulta de interés la observación de las mencionadas circunstancias en el colectivo de las mujeres con discapacidad, grupo que ha sido sujeto central de análisis en los Estudios de Género. Con este objeto, se realiza un recorrido por las diferentes aportaciones al tema desde las teorías de género y a partir del análisis que combina género y discapacidad. Se menciona además el sentido y la importancia de las publicaciones que al respecto se han editado; se aproxima su línea de trabajo con la muestra de algunos ejemplos. La presente contribución pretende acercar la reflexión alrededor de la construcción de la diferencia en las mujeres con discapacidad, como grupo "minorizado" en la sociedad.

this recommendation algorithm based on User-Item Attribute Rating Matrix (UIARM) can solve the cold-start problem, but the recommended low efficiency, poor quality. The use of Multi-Attribute Rating Matrix (MARM) can solve this problem; it can reduce the computation time and improve the recommendation quality effectively. The user information is analyzed to create their attribute-tables. The user's ratings are mapped to the relevant item attributes and the user's attributes respectively to generate a User Attribute-Item Attribute Rating Matrix. After UAIARM is simplified, MARM will be created. When a new item/user enters into this system, the attributes of new item/user and MARM are matched to find the N users/item with the highest match degrees as the target of the new items or the recommended items. Experiment results validate the cold-start recommendation algorithm based on MARM is efficient.

The simplest and most widely endorsed elucidation of the notions of truth and falsehood is given in Aristotle’s dictum: “to say of what is not that it is, and of what is that it is not, is false; while to say of what is that it is, and of what is not that it is not, is true”. Nowadays, while some take the dictum as the first Statement of truth as correspondence, the dictum may also be seen as a first Statement of deflationism. Deflationism holds that the essential about truth is captured in equivalence schemas for truth. Similar schemas are usually put forward for falsity. Can deflationism coherently deny bivalence? I will argue that it cannot since the putative counterexamples to bivalence also falsify the relevant truth-schemas. The attempts made to render the supposition of counter examples to bivalence compatible with the truth-schemas usually take two steps: in the first place, they try to deal with the way we can reject that a relevant item is bivalent without self-contradiction, and, in the second place, they try to explain how, although there are gaps, the schemas for truth and falsehood are still correct. I will argue that these attempts fail, since they are ad hoc or generally ungrounded. So, either deflationism is in adequate as an account of truth, or there cannot be counterexamples to bivalence. I conclude that it is not only deflationism that faces this dilemma; anyone who defends that some version or other of the truth-schemas is correct faces the same difficulties as the deflationist. This would corne as no surprise for Aristotle. His dictum about truth was followed by a Statement of bivalence: “so that he who says of anything that it is, or that it is not, will say either what is true or what is false”.
