Extant research examining the effects of top management team (TMT) gender diversity on firm performance report equivocal findings. We seek to enhance understanding of this critical relationship in the context of an acquisition, which necessitates changes in one or both firms during a process characterized by non-routine decisions, time pressures, high uncertainty, and frequent debates among strategic leaders. Specifically, we examine the effects of gender diversity of top management and female executives’ formal and informal power on post-deal performance. Our results indicate gender diversity has negative effects on post-deal performance. Further, in a subsample of acquirers with gender diverse teams, our results reveal that female executives’ structural power and ownership power have negative performance effects, while power conferred through an elite education has positive performance effects. Our findings highlight the need to expand gender diversity research to consider the strategic context facing diverse TMTs and power dynamics among them.

This research paper describes a validation study evaluating the ability of IceTag accelerometers (Peacock Technology, UK) to detect play behaviour in weaned dairy calves. Play behaviour is commonly observed in young animals and is regarded as an indicator of positive welfare states. Eight Holstein Friesian calves aged three to five months old were monitored using leg-mounted accelerometers for 48 h. Data generated by accelerometers to quantify calf activity included step count, lying times and a proprietary measure of overall activity termed ‘motion index’ (MI). Calf behaviour was filmed continuously over the same 48-h period using closed circuit television cameras and analysed using one-zero sampling to identify the presence (1) or absence (0) of play within each 15-min time period. A positive correlation between MI and visually recorded play was found. Visual observations were compared with accelerometer-generated data and analysed using 2 × 2 contingency tables and classification and regression tree analysis. A MI value of ≥69 was established as the optimum threshold to detect play behaviour (sensitivity = 94.4%; specificity = 93.6%; balanced accuracy = 94.0%). The results of this study suggest that accelerometer-generated MI data have the potential to detect play behaviour in weaned dairy calves in a more time efficient manner than traditional visual observations.

The years between 1890 and 1914 saw several prominent studies from statesmen-administrators comparing British India with the Roman empire. These were not the self-congratulatory comparisons of earlier decades, but serious comparative studies aimed at learning practical lessons from Rome's successes and failures. To gain a clearer picture of the significance of these analogies and how they were used, the Indian Civil Service (ICS) examination papers from the same period are analysed. It is argued that, following a move in 1892 to make the ICS a fully graduate service, the Civil Service commissioners showed a sustained interest in asking candidates to compare India (and the wider British empire) with the empires of Rome and Greece. Rome was considered particularly relevant for the directly ruled parts of the empire, with a focus on provincial administration and frontier defence, while Athens was preferred for questions of colonial federation. In the final section, the spread of subjects and weighting of marks within the examination are considered. It is argued that a series of changes post-1892 were designed to favour candidates who had studied Classics at university enabling them to obtain a higher proportion of the overall marks than those specializing in other subjects.

In 31 patients, Phaeoacremonium parasiticum was recovered from bronchoscopy specimens (biopsies and aspirates). The pseudo-outbreak was caused by contaminated ice used to control hemorrhage during bronchoscopy and was associated with deficiencies in equipment cleaning. The bronchoscopy technique was modified, the ice dispenser was disinfected, bronchoscope reprocessing was improved, and there were no recurrences.
