Acute Asthma Epidemics, Weather and Pollen in England, 1987-1994

Recent epidemics of acute asthma have caused speculation that, if their causes were known, early warnings might be feasible. In particular, some epidemics seemed to be associated with thunderstorms. We wondered what risk factors predicting epidemics could be identified. Daily asthma admissions counts during 1987-1994, for two age groups (0-14 yrs and > or = 15 yrs), were measured using the Hospital Episodes System (HES). Epidemics were defined as combinations of date, age group and English Regional Health Authority (RHA) with exceptionally high asthma admission counts compared to the predictions of a log-linear autoregression model. They were compared with control days 1 week before and afterwards, regarding seven meteorological variables and 5 day average pollen counts for four species. Fifty six asthma epidemics were identified. The mean density of sferics (lightning flashes), temperature and rainfall on epidemic days were greater than those on control days. High sferics densities were overrepresented in epidemics. Simultaneously high sferics and grass pollen further increased the probability of an epidemic, but only to 15% (95% confidence interval 2-45%). Two thirds of epidemics were not preceded by thunderstorms. Thunderstorms and high grass pollen levels precede asthma epidemics more often than expected by chance. However, most epidemics are not associated with thunderstorms or unusual weather conditions, and most thunderstorms, even following high grass pollen levels, do not precede epidemics. An early warning system based on the indicators examined here would, therefore, detect few epidemics and generate an unacceptably high rate of false alarms.

Unlocking Characteristics of Outstanding Leadership in Schools and Colleges in England

The workshop will invite participants to engage in a discussion of the characteristics of outstanding leadership by taking part in an interactive activity which we have developed and used in different types of schools and colleges in England. The activity uses Q-methodology to develop and refine characteristics of outstanding leaders and outstanding leadership in education from a range of stakeholder perspectives. Q-methodology is a research method which originates from psychology and is used to study people's subjective viewpoints. We are applying the methodology to the study of enacted leadership practice in different educational contexts. Our sample of stakeholders consists of school and college leaders, governors, middle leaders, teachers, teacher educators, researchers and scholars in educational leadership and management research and practice. The range of contexts in which they work represents different age phases of education; primary, secondary and further education colleges, urban and rural schools and colleges and selective and non-selective schools. In the workshop participants will be invited to take part in the Q-sort activity we have used with in our research, using statements from leadership theory and practice. The Q-sort will be followed by discussion and reflection on the statements in relation to participants’ own experiences of leadership, management and governance in different contexts.
