Women’s career in theory and practice: time for change?

Abstract: One result of domination of management as being male paradigm is that women managers are out of place, in foreign territory, “travellers in a male world”. The model of the successful manager has traditionally been masculine and while these stereotypes remain, they succeed in maintaining the dominant place for men in management. This is evident in both the theory underpinning and the actual experience of career in management. Indeed, the traditional working pattern of education, full‐time career and retirement is based on the typical working lives of men. There is no single typical working pattern for modern women. It is clear that, while male career models remain and women are the ones to step off the fast track to meet family responsibilities, they will continue to be at a competitive disadvantage in career advancement. Reviews the literature concerning women and career and argues that the importance of offering new conceptions of career based on an understanding that women’s experiences are different from men cannot be underestimated. Areas for further research and the implications for organisations are also highlighted.

Effects of supramaximal exercise on the electromyographic signal

Abstract: Aim: To determine the neuromuscular recruitment characteristics during supramaximal exercise. Methods: Ten healthy subjects completed the Wingate anaerobic test (WAT) cycling protocol. Electromyographic (EMG) data and rate of fatigue were recorded throughout the cycling. Results: The mean (SD) rate of fatigue (decrease in power output) was 44.5 (8.6)%. No significant change was found in EMG amplitude. A significant decrease (p<0.01) in mean power frequency spectrum was found over the 30 second period. Conclusions: During WAT, mean power frequency spectrum was attenuated with no decline in EMG amplitude, which may be caused by an accumulation of metabolites in the periphery. However, it is also possible that the feedback loop from intramuscular metabolism to the central nervous system is unable, within the 30 second period of the WAT, to affect neural recruitment strategy.

New generation perovskite solar cells with solution-processed amino-substituted perylene diimide derivative as electron-transport layer

Abstract: In this study, for the first time, we introduced amino-substituted perylene diimide derivative (N-PDI) as an alternative electron transport layer (ETL) to replace the commonly used TiO2 in planar heterojunction perovskite solar cells. Two types of device structures, i.e., glass/FTO/N-PDI/CH3NH3PbI3−xClx/spiro-MeOTAD/Au and polyethylene terephthalate PET/ITO/N-PDI/CH3NH3PbI3−xClx/spiro-MeOTAD/Au, were fabricated on both rigid and flexible substrates using room-temperature solution processing technique. Based on the proposed device structures, power conversion efficiency (PCE) of 17.66% was obtained based on glass/FTO rigid substrates, and a PCE of 14.32% was achieved based on PET/ITO flexible substrates. The results showed that the terminal amino group in N-PDI enhanced the wetting capability of the surfaces to perovskite, reduced the surface work function of the FTO substrate and passivated the surface trap states of the perovskite films. These results confirm that small molecule semiconductor N-PDI can serve as an effective electron-transport material for achieving high-performance perovskite solar cells and draw molecular design guidelines for electron-selective contacts with perovskite.
