Gendering the careers of young professionals: some early findings from a longitudinal study. in Organizing/theorizing: developments in organization theory and practice

Wonders whether companies actually have employees best interests at heart across physical, mental and spiritual spheres. Posits that most organizations ignore their workforce – not even, in many cases, describing workers as assets! Describes many studies to back up this claim in theis work based on the 2002 Employment Research Unit Annual Conference, in Cardiff, Wales

Neurogenic mechanisms contribute to hypertension in mice with disruption of the K-Cl cotransporter KCC3

The neurodegenerative disorder Andermann syndrome is caused by mutations of the K-Cl cotransporter KCC3. Mice with a targeted disruption of the corresponding gene, Slc12a6, reproduce neurodegeneration of the peripheral and central nervous system (CNS) and display arterial hypertension. Kcc3 is expressed in numerous tissues, including the CNS and vascular smooth muscle cells. As the intracellular chloride concentration may influence myogenic tone and hence blood pressure, we measured the chloride concentration in vascular smooth muscle cells. It was indeed increased in superficial brain arteries and saphenous arteries of Kcc3(-/-) mice. Isolated saphenous arteries and their third-order branches, however, reacted indistinguishably to changes in intravascular pressure, stimulation of alpha1-adrenoreceptors, exogenous nitric oxide, or blockade of calcium-activated chloride channels. Likewise, the responses to alpha1-adrenergic stimulation or exogenous nitric oxide in vivo were identical in both genotypes. These results argue against a major vascular-intrinsic component of arterial hypertension in Kcc3(-/-) mice. In contrast, either alpha1-adrenergic blockade or inhibition of ganglionic transmission abolished the difference in arterial blood pressure between both genotypes. This demonstrates a neurogenic component in the maintenance of this phenotype, which is further supported by an increase of urinary norepinephrine and epinephrine excretion in Kcc3(-/-) mice. Our data indicate that local control of myogenic tone does not require KCC3 and that hypertension in Kcc3(-/-) mice depends on an elevated sympathetic tone

A model of political leadership

In this article we develop a model of political leadership. In doing so, we analyse the challenges facing political leaders in local government in England and Wales. We use this analysis as a basis for broader theorizing: about leadership at other levels of government and in other countries. The scope for applying extant accounts of leadership in these domains can be enhanced by considering the relational complexities that characterize the environment within which political leaders act; by doing so we offer an agenda for research. We describe the context for political leaders in terms of figurational sociology, where figurations denote interdependent networks of social relations. These take shape in different arenas of action, and are partly influenced by the different roles that political leaders undertake. These figurations are also constituted differently given the diversity inherent in the context for enacting political leadership. We propose a conceptual model that serves both as a heuristic framework to organize conceptualization of this understudied area, and to orient future research
