Having a first baby is considered a major life event, due to significant role change impacting on the ordinary and familiar activities the new mother performs every day. The aim of this study was to explore changes in the occupational lives of first time mothers. A concurrent nested strategy of enquiry was used. Quantitative data via the Modified Interest Checklist and the Role Checklist was ne...

Phytoplankton taxa composition of the Caspian Sea were evaluated by using samples collected at 12 stations along the Iranian coast of the Caspian Sea between 1996 and 2010. This study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). The dominant species were the...

In many cell types it is evident that the small GTPases Rac and Rho regulate each other's activities. What is unclear is exactly how this regulation occurs. To further elucidate this interaction we examined the activities of Rac1 and Rho1 in Drosophila cellular immune surveillance cells. In larvae the cellular immune response involves circulating cells (hemocytes) that can be recruited from a h...

Rnpalidia marginata, a tropical, primitively eusocial, polistine wasp, is unusual in that the queen (the sole egg-layer) is neither the most behaviorally dominant nor the most active individual in the colony. The queen by herself rarely ever initiates interactions toward her nest mates or unloads returning foragers. There are always a few workers in the colony who are more dominant and acth"e t...

Endothelial cells (ECs) exposed to cyclic strain induce gene expression. To elucidate the signaling mechanisms involved, we studied the effects of cyclic strain on ECs by using early growth response-1 (Egr-1) as a target gene. Cyclic strain induced a transient increase of Egr-1 mRNA levels that resulted in an increase of binding of nuclear proteins to the Egr-1 binding sequences in the platelet...

We present evidence that a multitude of mid-frontal event-related potential (ERP) components partially reflect a common theta band oscillatory process. Specifically, mid-frontal ERP components in the N2 time range and error-related negativity time range are parsimoniously characterized as reflections of theta band activities. Forty participants completed three different tasks with varying stimu...

INTRODUCTION: A high level of muscle strength is regarded as a prerequisite for success in many sporting activities, especially in combat sports (Janiak & Krawczyk, 1995). Maximal muscle torque measurements under static conditions have been widely used in evaluating the strength of athletes practicing diverse sports (Buœko, 1998; Bober & Pietraszewski, 1996; Janiak & Krawczyk, 1995; Trzaskoma, ...

Recent findings on motor lateralization have revealed consistent differences in the control strategies of the dominant and nondominant hemisphere/limb systems that could have implications for hemiplegic stroke patients. Studies in stroke patients have demonstrated deficiencies in the ipsilesional arm that reflect these distinctions; patients with right-hemisphere damage tend to show deficits in...

The dominant interpretation of the function and role of the CIO is technology-related with business-ICT alignment as a core concept. We criticize this vision as a product of the dominant interpretive scheme and show how the logic of this scheme restricts the worldview of CIO’s and researchers. To overcome these restrictions, we adopt an alternative interpretive scheme based on our twenty years ...
