The purpose of our project was the implementation of an application-layer covert channel, with guaranteed con dentiality via cha ng. A covert channel is a means of passing information between two parties in such a manner that the existence of the communication channel itself is not obvious to the casual observer. Additionally, the implementation of a covert channel is enhanced through encryptio...

Objectives: A commercial chemical, biological, radiological and nuclear (CBRN) protective covert garment has recently been developed with the aim of reducing thermal strain. A covert CBRN protective layer can be worn under other clothing, with equipment added for full chemical protection when needed. However, it is unknown whether the covert garment offers any alleviation to thermal strain duri...

The creation of an artwork requires motor activity. To what extent is art appreciation divorced from that activity and to what extent is it linked to it? That is the question which we set out to answer. We presented participants with pointillist-style paintings featuring discernible brushstrokes and asked them to rate their liking of each canvas when it was preceded by images priming a motor ac...

The present study examined the association between covert narcissism and internalizing symptoms (i.e., shame, anxiety) in adolescents following an ego threat. Participants were 132 adolescents (101 males, 30 females, 1 not reported), ages 16–19 (M = 16.81 years, SD = .81), attending a residential program. Participants were randomly assigned to one of three feedback conditions (i.e., positive, n...

Objective: For decades, both theory and research have focused on the role of self-esteem and shame in constructing narcissistic traits. However, studies on the exact relationship between these two and overt and covert facets of narcissism have been equivocal.  Methods: The current study is correlational. It examined these relationships among 308 Iranian college students (155 males, 153 femal...

The purpose of the work reported here is to test the hypothesis that natural genetic transformation in the bacterium Bacillus subtilis has evolved as a DNA repair system. Specifically, tests were made to determine whether transformation functions to provide DNA template for the bacteria] cell to use in recombinational repair. The survivorship and the homologous transformation rate as a function...

The existing literature on parental control and children's diets is confusing. The present paper reports two studies to explore an expanded conceptualisation of parental control with a focus on overt control which 'can be detected by the child' and covert control which 'cannot be detected by the child'. In study 1, 297 parents of children aged between 4 and 11 completed a measure of overt contr...

Proactive and reactive inhibition are generally intended as mechanisms allowing the withholding or suppression of overt movements. Nonetheless, inhibition could also play a pivotal role during covert actions (i.e., potential motor acts not overtly performed, despite the activation of the motor system), such as Motor Imagery (MI). In a previous EEG study, we analyzed cerebral activities reactive...
