Cultures within culture: Unity and diversity of two generations of employees in state-owned enterprises

This study adopts integration and differentiation perspectives to examine why unity and diversity of organizational cultures emerged as a function of economic reform, and how subcultural differences were reflected in employees' perceptions of cultural practices. Data were gathered from in-depth interviews and a large-scale survey in two large, state-owned enterprises in north-east China. Results indicated that, although all employees were oriented towards a common set of cultural themes, the two generations of employees did not exemplify the themes in the same way. Specifically, unity was illustrated by employees' desire to maintain Harmony and to reduce Inequality. Diversity was revealed by first-generation employees' higher ratings on Loyalty, Security and even Bureaucracy. The findings are discussed in the light of traditional Chinese cultural values, political ideology and the social context. Implications are drawn for organizational cultural theory and research.

Effects of pathophysiological concentrations of albumin on NHE3 activity and cell proliferation in primary cultures of human proximal tubule cells

The progression of renal disease correlates strongly with hypertension and the degree of proteinuria, suggesting a link between excessive Na+ reabsorption and exposure of the proximal tubule to protein. The present study investigated the effects of albumin on cell growth and Na+ uptake in primary cultures of human proximal tubule cells (PTC). Albumin (1.0 mg/ml) increased cell proliferation to 134.1 +/- 11.8% (P < 0.001) of control levels with no change in levels of apoptosis. Exposure to 0.1 and 1.0 mg/ml albumin increased total Na-22(+) uptake to 119.1 &PLUSMN; 6.3% (P = 0.005) and 115.6 &PLUSMN; 5.3% (P < 0.006) of control levels, respectively, because of an increase in Na+/H+ exchanger isoform 3 (NHE3) activity. This was associated with an increase in NHE3 mRNA to 161.1 +/- 15.1% (P < 0.005) of control levels in response to 0.1 mg/ml albumin. Using confocal microscopy with a novel antibody raised against the predicted extracellular NH2 terminus of human NHE3, we observed in nonpermeabilized cells that exposure of PTC to albumin (0.1 and 1.0 mg/ml) increased NHE3 at the cell surface to 115.4 &PLUSMN; 2.7% (P < 0.0005) and 122.4 +/- 3.7% (P < 0.0001) of control levels, respectively. This effect was paralleled by significant increases in NHE3 in the subplasmalemmal region as measured in permeabilized cells. These albumin-induced increases in expression and activity of NHE3 in PTC suggest a possible mechanism for Na+ retention in response to proteinuria.

Phobic anxiety in 11 nations: part II. Hofstede's dimensions of national cultures predict national-level variations

Hofstede's dimensions of national cultures termed Masculinity-Femininity (MAS) and Uncertainty Avoidance (UAI) (Hofstede, 2001) are proposed to be of relevance for understanding national-level differences in self-assessed fears. The potential predictive role of national MAS was based on the classical work of Fodor (Fodor, 1974). Following Fodor, it was predicted that masculine (or tough) societies in which clearer differentiations are made between gender roles (high MAS) would report higher national levels of fears than feminine (or soft/modest) societies in which such differentiations are made to a clearly lesser extent (low MAS). In addition, it was anticipated that nervous-stressful-emotionally-expressive nations (high UAI) would report higher national levels of fears than calm-happy and low-emotional countries (low UAI), and that countries high on both MAS and UAI would report the highest national levels of fears. A data set comprising 11 countries (N > 5000) served as the basis for analyses. As anticipated, (a) high MAS predicted higher national levels of Agoraphobic fears and of Bodily Injury-Illness-Death fears; (b) higher scores on both UAI and MAS predicted higher national scores on Bodily Injury-Illness-Death fears, fears of Sexual and Aggressive Scenes, and Harmless Animals fears; (c) higher UAI predicted higher national levels of Harmless Animals, Bodily Injury-Illness-Death, and Agoraphobic fears.

Fast accumulation of few polyhedra mutants during passage of a Spodoptera frugiperda multicapsid nucleopolyhedrovirus (Baculoviridae) in Sf9 cell cultures

Baculoviruses are a group of viruses that infect invertebrates and that have been used worldwide as a biopesticide against several insect pests of the Order Lepidoptera. In Brazil, the baculovirus Spodoptera frugiperda multicapsid nucleopolyhedrovirus (SfMNPV, Baculoviridae) has been used experimentally to control S. frugiperda (Lepidoptera: Noctuidae), an important insect pest of corn (maize) fields and other crops. Baculoviruses can be produced either in insect larvae or in cell culture bioreactors. A major limitation to the in vitro production of baculoviruses is the rapid generation of mutants when the virus undergoes passages in cell culture. In order to evaluate the potential of in vitro methods of producing SfMNPV on a large-scale, we have multiplied a Brazilian isolate of this virus in cell culture. Extensive formation of few polyhedra mutants was observed after only two passages in Sf9 cells.
