Robust stable pole-placement-based adaptive control of continuous linear systems with two parametrical estimation schemes

This paper deals with the pole-placement-type robust adaptive control of continuous linear systems in the presence of bounded noise and a common class of unmodeled dynamics provided that two estimation schemes are used in parallel. Both estimation schemes are introduced in order to minimize the plant identification error by selecting, as plant parameter estimates, a convex combination of both parameter estimates which leads to the selection of one of the estimation schemes, via a switching rule, on time intervals of at least a minimum prefixed residence duration. The weights of the individual parameter vector estimates are provided at each time by an optimization or suboptimization scheme for a quadratic loss function of the possibly filtered tracking error and/or control input. The robust stability of the overall adaptive scheme is ensured by an adaptation relative dead zone which takes into account the contribution of the unmodeled dynamics and bounded noise. The basic results are derived for two different estimation strategies which have either a shared regressor with the plant or individual regressors for the input contribution and its contributed derivatives. In this second case, the plant input is obtained from a similar convex combination rule as the one used for the estimators in the first approach. An extension of the basic strategies is also pointed out including a combined use of the (sub) optimization scheme with a supervisor of past measures for the on-line calculation of the estimator weights in the convex combination. Finally, the extension of the scheme for the use of any number of parametrical estimators is focused on.     

Bullying in Italian schools: the role of perceived teacher unfairness

The principal aim of the study is to examine the role of perceived teacher unfairness in predicting bullying behaviour. Data were taken from the “Health Behaviour in School Aged Children” project, a cross-sectional survey investigating health behaviours among early adolescents in selected European countries. Bullying behaviour (bully, victim, and bully/victim), perceived teacher unfairness and others confounding factors were measured through a self-administered questionnaire filled out by a representative sample of 4,386 (48.4% males) Italian students (11, 13, and 15 years old). Covariates included demographic characteristics, socioeconomic status, school performance and other psychological factors. After adjusting for age and gender, teacher unfairness showed a significant association with being a bully (OR = 1.59; CI = 1.40–1.80) and a bully or victim (OR = 1.47; CI = 1.21–1.78). This relationship remained significant after additional adjustment for several potential confounding factors. Results show that characteristics of the school setting such as teacher unfairness can be significant predictors of involvement in bullying behaviour among early adolescents.     

Accounting for exogenous influences in performance evaluations of teachers

Students’ evaluations of teacher performance (SETs) are increasingly used by universities. However, SETs are controversial mainly due to two issues: (1) teachers value various aspects of excellent teaching differently, and (2) SETs should not be determined on exogenous influences. Therefore, this paper constructs SETs using a tailored version of the non-parametric Data Envelopment Analysis approach. In particular, we account for different values and interpretations that teachers attach to ‘good teaching’. Moreover, we reduce the impact of measurement errors and a-typical observations, and account explicitly for heterogeneous background characteristics arising from teacher, student and course characteristics.
