Getting on or getting by? Employee flexibility and coping strategies for home and work

Abstract: Recent speculation about the impact on family life of contemporary patterns of work has prompted considerable and concerted social research activity in which the workplace and household have figured prominently. This article extends these studies to examine employment in prototypical new sectors of the economy, namely call centres and software, which at the time of the study were enjoying spectacular growth. Employees in both sectors reported spillover from work to home, though the extent, nature and intensity of spillover varied significantly between the sectors. The study identified the different and hitherto unexplored ways in which employees in these different sectors attempt to cope with complex articulations between home and work, and the varying resources which they bring to bear in doing so. Contemporary work settings indicate little change from more established sectors in that gender, status and labour market strength are important factors in offering work boundary discretion.

Patterns of variation in the lipid class and fatty acid composition of Nannochloropsis oculata (Eustigmatophyceae) during batch culture

Abstract: Changes in the lipid and fatty acyl compositions of the marine microalga Nannochloropsis oculata Droop were examined during a batch culture growth cycle. During the early phase of batch culture the cellular proportion of triacylglycerols (TAG) increased. This was in addition to the increases in TAG observed in many microalgal species in the stationary-phase. Concomitant increases in the relative proportions of both saturated and monounsaturated fatty acids and decreases in the proportion of polyunsaturated fatty acids in total lipid were also associated with this phase. The separated individual lipid classes were found to have characteristic fatty acyl compositions. The relative proportion of lipid per cell, the relative proportions of the individual lipid classes and the fatty acyl compositions of the individual classes were all subject to variability during the growth cycle. The changing total lipid fatty acyl composition of N. oculata was found to be determined by the proportion of the total lipid present as TAG. The data suggest that the changes observed in the fatty acyl composition of N. oculata are a result of the partitioning of photosynthetically fixed carbon between polar and neutral lipid class biosynthesis and fatty acyl desaturation and elongation pathways. The effect of such a partitioning of carbon is discussed in relation to the effects of environmental variables and growth phase upon the balance of lipid class and polyunsaturated fatty acids (PUFA) synthesis in marine microalgae.

Nonlinear Dynamics in Real-Time Equity Market Indices: Evidence from the United Kingdom

Abstract: This paper tests for the presence of nonlinear dependence and chaos in real-time returns on the U.K. FTSE-100 Index using a six-month sample of about 60,000 observations. Since there is clear evidence of nonlinearity, the authors follow other researchers in this field by applying the same tests to the residuals from a GARCH process fitted to the data in order to find out whether or not the nonlinearity can be explained by this type of model. In the event, their results suggest that GARCH can explain some but not all of the observed nonlinear dependence. Copyright 1995 by Royal Economic Society.
