Recent observations indicate that sex and level of steroid hormones may influence cortical networks associated with specific cognitive functions, in particular visuo-spatial abilities. The present study probed the influence of sex, menstrual cycle, and sex steroid hormones on 3D mental rotation and brain function using 3-T fMRI. Twelve healthy women and 12 men were investigated. Menstrual cycle...

The present study investigated the effect of pragmatic eliciting tasks on EFL pre-intermediate learners speaking proficiency. Thus this study aimed at comparing the English language learners who practiced pragmatic eliciting tasks and the ones who used traditional speaking activities such as questions and answers, discussion, etc. In doing so, 40 learners out of 80 were selected through Oxford ...

the difficulty of assessing the writing skill is well known. different testing facets seem to affect the result of assessing the writing skill. in addition to the writer’s ability, the topic of the writing task, and methods of rating may contribute to the writer’s score. in this study, 50 efl learners wrote four different types of writing tasks (convincing, describing, instructing, and explaini...

Human-human joint-action in short-cycle repetitive handover tasks was investigated for a bottle handover task using a three-fold approach: work-methods field studies in multiple supermarkets, simulation analysis using an ergonomics software package and by conducting an in-house lab experiment on human-human collaboration by re-creating the environment and conditions of a supermarket. Evaluation...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

task flaw: If an abstract cannot be decomposed, the decision that added the abstract task is implicated in the failure. IPC threat: An IPC threat arises when the effect of some tasks violates an IPC. In this case, the decision that introduced the IPC and the decision that introduced the threatening task are both implicated. Codesignation violation: A codesignation violation occurs when two vari...

Rework cycle is at the heart of modeling projects, one of the major application areas of system dynamics. In this paper we introduce a new formulation for rework cycle in which multiple defects may exist in a task. We compare the performance of this model with three other formulations, two adopted from system dynamics literature and one agent-based formulation. This comparative study illustrate...

Large network environments, such as enterprise Intranets and the Internet, have moved to the center stage in the field of software deployment. The connectivity inherent in these environments provides a new tool that deployment solutions can leverage to perform a comprehensive software deployment life cycle. This life cycle covers a wide range of deployment tasks, including release, install, upd...

Women have periodic physiologic change of menstruation. There is a possibility to be influenced the physical and mentally in the female. It is necessary to support a comfortable life and work for female. The relationship between workload and stress that was taken the menstrual cycle into consideration had been examined on mental tasks in this research. Menstrual phase, follicular phase and prem...

Various studies have shown fluctuations in task performance during the menstrual cycle. The aim of this study was to see the effects of the menstrual cycle on performing fine motor and spatial tasks of different level of complexity in twenty students aged 18 to 21 years, with regular menstrual cycle (28 to 30 days). The students performed O'Connor Finger Dexterity Test and mental rotation test ...
