Background: The ‘Organizational Justice’ concept is used in order to determine whether the administrator is fair to his personnel or not. It is said that those who get bullied are usually terrorized, annoyed, excluded, belittled, deprived of resources, isolated and prevented from claiming rights. Objective: The purpose of this study is to determine nurses...

Previous research by Rachman and de Silva (1978, Behaviour Research and Therapy, 16, 233-248) and by Salkovskis and Harrison (1984, Behaviour Research and Therapy, 22, 549-552) has shown that abnormal and normal obsessions are similar in content. The present study examined whether the same is true for abnormal and normal rituals. A sample of normal subjects (N = 150) were asked about their idio...

An approach is proposed for robust online behaviour recognition and abnormality detection based on discovering natural grouping of bebaviour patterns through unsupervised learning and a time accumulative reliability measure. A novel behaviour learning model and a run-time accumulative reliability measure are introduced to determine both the natural groupings of possible normal behaviour classes...

In this paper, we introduce fractional order of a planar fractional prey-predator system with a nonmonotonic functional response and anti-predator behaviour such that the adult preys can attack vulnerable predators. We analyze the existence and stability of all possible equilibria. Numerical simulations reveal that anti-predator behaviour not only makes the coexistence of the prey and predator ...

Machines of all kinds from vehicles to industrial equipment are increasingly instrumented with hundreds of sensors. Using such data to detect “anomalous” behaviour is critical for safety and efficient maintenance. However, anomalies occur rarely and with great variety in such systems, so there is often insufficient anomalous data to build reliable detectors. A standard approach to mitigate this...

In recent studies of equine stereotypic behaviour, data on levels of cortisol and beta-endorphin Ž . BE have been limited and sometimes contradictory. The current research aimed to investigate, in a large number of horses, the relationships between these compounds and equine stereotypic Ž . behaviour. Plasma and salivary cortisol levels were measured in stereotypic ns46 and normal Ž . horses ns...

This study, split into three parts, describes the behavioural changes in eight adult gorillas (Gorilla gorilla gorilla) housed at several European zoos, in response to environmental manipulations. These manipulations were aimed at encouraging more normal behaviour in captive gorillas, by increasing the complexity of food presentation (hiding food in plastic tubes, in holes, in woodwool, etc). I...
