colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (ca1). in this study, the effect of the alkaloid in ca1 on the behaviors in the conditioning task was measured. injections of colchicine (1,5 μg/rat, intra-ca1) was performed in the male wistar rats, while the animals were s...

Purpose – This study proposes a nuanced perspective for conceptualizing interpersonal counterproductive work behaviors (ICWBs) by distinguishing them into behaviors that hinder other workers’ task performance (task-focused ICWBs), and those that are personal in nature (person-focused ICWBs). A relational stress perspective is adopted to examine work-based dependence relational stressor and nega...

Programming robot or virtual agent behaviors can be a challenging task, and makes attractive the prospect of automatically learning the behaviors from the actions of a human demonstrator. However, learning complex behaviors rapidly from a demonstrator may be difficult if they demand a large number of training samples. We describe an architecture for rapid learning of recurrent behaviors from de...

In a robotic soccer team, goalkeeper is an important challenging role, which has different characteristics from the other teammates. This paper proposes a new learning-based behavior model for a soccer goalkeeper robot by using Petri nets. The model focuses on modeling and analyzing, both qualitatively and quantitatively, for the goalkeeper role so that we have a model-based knowledge of the ta...

the aim of this study was to compare the effects of three types of balancetraining: single task, dual task under fixed priority instructional set (fp) and dualtask under a variable priority instructional set (vp) on the balance of the elderly.the participants were 36 elderly over 65 years old from kerman province whowere randomly divided into three groups (each 12 subjects) based on burg pretes...

Personal task management (PTM) is a common human activity that is supported by a plethora of dedicated e-PTM tools. Yet, little is known about how and why PTM behaviors change over time, and how PTM tools can accommodate such changes. We studied changes in 178 participants’ PTM behaviors in a survey to inform the design of personalizable e-PTM tools that can accommodate changes over time. In fo...

This study examined how employees react to formal evaluations of organizational citizenship behaviors in performance appraisals. Using a sample of 107 business students with relevant job experience, this experimental study found that their reactions to such formal inclusion of organizational citizenship behaviors depended on their task performance. Respondents with high task performance, compar...
