Patient advocacy is an inherent component of professional nursing ethics; in other words, nurses' enough knowledge would be essential to gain a positive attitude towards nursing advocacy. Using a descriptive-analytic design, this study aimed to assess the correlation between nurses' perception and attitudes towards patient advocacy, amongst 385 nurses in Kerman, Iran; hence, a three-part questi...

The view that perception is direct holds that a perceiver is aware of or in contact with ordinary mind-independent objects, rather than mind-dependent surrogates thereof. In this paper I try to articulate an account of direct perception from a Gibsonian point of view, located within the wider terrain of cognitive science and psychology. James Gibson's ecological theory proposes that perception ...

k-means++ is a seeding technique for the k-means method with an expected approximation ratio of O(log k), where k denotes the number of clusters. Examples are known on which the expected approximation ratio of k-means++ is Ω(log k), showing that the upper bound is asymptotically tight. However, it remained open whether k-means++ yields an O(1)-approximation with probability 1/poly(k) or even wi...

Chronic tinnitus is a symptom with high prevalence. There is evidence that the tinnitus perception is related to unfavorable cortical plastic changes. In our recent study we have developed and evaluated a customized music training strategy that appears capable of both reducing cortical tinnitus related neuronal activity and alleviating subjective tinnitus perception. We hypothesize that the reg...

This paper describes a preliminary algorithm performing epilepsy prediction by means of visual perception tests and digital electroencephalograph data analysis. Special machine learning algorithm and signal processing method are used. The algorithm is tested on real data of epileptic and healthy persons that are treated in Kaunas Medical University Clinics, Lithuania. The detailed examination o...

In this paper, the “coarseness” texture property is modelled by means of fuzzy sets, relating representative coarseness measures (our reference set) with the human perception of this type of feature. In our study, a wide variety of measures are analyzed, and the coarseness human perception are collected from polls filled by subjects. The capability of each measure to discriminate different coar...
