The value-added of primary schools: what is it really measuring?

This paper compares the official value-added scores in 2005 for all primary schools in three adjacent LEAs in England with the raw-score Key Stage 2 results for the same schools. The correlation coefficient for the raw- and value-added scores of these 457 schools is around +0.75. Scatterplots show that there are no low attaining schools with average or higher value-added, and no high attaining schools with below average value-added. At least some of the remaining scatter is explained by the small size of some schools. Although some relationship between these measures is to be expected – so that schools adding considerable value would tend to have high examination outcome scores – the relationship shown is too strong for this explanation to be considered sufficient. Value-added analysis is intended to remove the link between a schools’ intake scores and their raw-score outcomes at KS2. It should lead to an estimate of the differential progress made by pupils, assessed between schools. In fact, however, the relationship between value-added and raw scores is of the same size as the original relationship between intake scores and raw-scores that the value-added is intended to overcome. Therefore, however appealing the calculation of value-added figures is, their development is still at the stage where they are not ready to move from being a research tool to an instrument of judgement on schools. Such figures may mislead parents, governors and teachers and, even more importantly, they are being used in England by OFSTED to pre-determine the results of school inspections

Measuring practice leadership in supported accommodation services for people with intellectual disability: Comparing staff-rated and observational measures

Background Studies incorporating staff-rated or observational measures of practice leadership have shown that where practice leadership is stronger, active support is better implemented. The study aim was to compare measures of practice leadership used in previous research to determine the extent of their correspondence. Method A subset of data from a longitudinal study regarding 29 front-line managers working across 36 supported accommodation services in Australia was used. An observed measure of practice leadership, based on an interview and observation of a front-line manager, was compared with ratings of practice leadership completed by staff. The quality of active support was rated after a 2-hour structured observation. Results Correlations between staff-rated and observed measures were non-significant. Only the observed measure was correlated with the quality of active support. Conclusions This study provides evidence to support using an observational measure of practice leadership rather than reliance on staff ratings

Dementia : towards a perceptual control theory perspective

Purpose: The purpose of this paper is to explore the psychosocial experiences of people living with dementia using a perceptual control theory (PCT) perspective. Design/methodology/approach:Conceptual paper. Findings: The paper suggests that people with dementia may control their perceptions by using four modes of control: control, automatic, passive observation and imagination. Research limitations/implications: The paper highlights how a perceived sense of “too little” or “too much” control can create psychological and emotional distress, as people with dementia seek to respond to the changing contextual circumstances of their lives. However, more work needs to be done to develop specific PCT informed strategies that may serve the goal of helping people who are living with dementia to maximise their functioning and alleviate their distress. Originality/value: The potential benefits of adopting a PCT perspective to understand the experiences of people living with dementia have only been explored in a relatively superficial way. This paper is a first attempt to develop a more considered analysis

Experiences of a transdiagnostic group, the Take Control Course, for clients with common mental health problems : a qualitative study

Objectives Despite the promising effectiveness findings for transdiagnostic groups, studies have not explored clients' experiences. There is a risk that clients could perceive that the content of transdiagnostic groups is not sufficiently tailored to their specific problems. Our aims were to examine whether a brief transdiagnostic group, the Take Control Course (TCC), was acceptable to participants and to explore participants' perceptions of psychological change. Methods Qualitative data were collected via 12 semistructured, in‐depth interviews. Data collection and thematic analysis were concurrent and iterative. Results Three superordinate themes were identified: “Style and format,” “Control and flexibility,” and “Change.” The flexible group format was appreciated, as participants felt able to engage at their own pace and adapt relevant aspects. Greater clarity regarding what was within participants' control reduced distress and enabled effective pursuit of valued goals. Participants described significant (predominantly gradual) changes, including substantial improvements within relationships. Conclusions The transdiagnostic format did not prevent participants experiencing the TCC as individually relevant. The flexibility and consistent theoretical framework seemed to contribute to this. The results indicated that greater consideration of control and mindfulness allowed greater cognitive flexibility, an ability to reprioritize and let go of unhelpful habits, which better enabled participants to meet their goals. Implications for group therapy include (a) clearly explaining the format of such groups to clients and (b) providing flexibility in the way the group is delivered where possible. Additional qualitative studies of transdiagnostic groups are required to establish if themes generalize to other transdiagnostic groups

First records of the antlion genus Solter Navás from southern Africa, with description of a new species (Neuroptera: Myrmeleontidae: Myrmecaelurini)

A new species of Solter Navás is described from South Africa, representing the first record of this genus from Africa south of the equator. The new species provides a significant extension to the known distribution range of this predominantly Palaearctic genus. The species described here is characteristically reddish brown with a banded abdomen, and was recorded at three localities in arid rocky areas in the Northern Cape Province of South Africa.The Northern Cape Department of Nature Conservation and the JRS Foundation.http://www.mapress.com/zootaxa/hb201

Biology and systematics of some southern African myrmeleontoid insects (order Neuroptera)

The biology of southern African Myrmeleontidae and Nemopteridae (Neuroptera, Myrmeleontoidea) was studied with special emphasis on the nemopterid subfamily Crocinae. The superfamily Myrmeleontoidea is considered to be a monophyletic group derived from ancestors similar to the family Nymphidae. The Myrmeleontidae and Nemopteridae are the most highly evolved families, and the Nemopteridae have a sistergroup relationship with the other four myrmeleontoid families. Within the Nemopteridae, the Crocinae are considered more advanced than the subfamily Nemopterinae. An account of previous work on the two families is presented: literature relating to the Myrmeleontidae is catalogued in appendix 2 and publications dealing with the Nemopteridae are surveyed in the text . Biological and morphological information derived from the immature stages as well as the adults was used in the systematic study of the two families. The geographical distribution and phylogeny of the Myrmeleontoidea is discussed with particular reference to the Myrmeleontidae and Nemopteridae. The Myrmeleontidae have a world wide distribution whilst the Nemopteridae are more restricted, being limited to the arid and semi-arid regions of the world. It is concluded that the two families originated on Gondwanaland, and their present distribution is explained on the basis of evidence provided by plate tectonics. In southern Africa, the Myrmeleontidae show two distributional trends: there is a distinct western fauna including many endemics and an eastern fauna which comprises taxa with a wide distribution in central and east Africa, extending their ranges into the eastern parts of the subregion. The Nemopteridae occur predominantly on the western side of the subcontinent and over 90% of the species are endemic to southern Africa. A systematic revision of the southern African Crocinae is presented and summarized in a set of illustrated keys to the adults and larvae. There are now ten known crocin species in four genera from the subregion, four species being described for the first time in this thesis. The larvae of all ten species and the eggs of seven, have been correlated with the adults and are described. Two crocin genera, Concroce and Thysanocroce, have larvae with short prothoraxes, whilst those in Laurhervasia and Tjederia are elongated. Larvae of the first two genera live in plant detritus under rocks and in crevices whereas larvae of the latter two genera inhabit small dusty caves. These findings on the Myrmeleontidae and Nemopteridae are discussed in the context of general systematic theory, phylogeny and zoogeography

The assessment and modeling of perceptual control: a transformation in research methodology to address the replication crisis

Replication in the behavioral sciences is a matter of considerable debate. We describe a series of fundamental interrelated conceptual and methodological issues with current research that undermine replication and we explain how they could be addressed. Conceptually, we need a shift (a) from verbally described theories to mathematically specified theories, (b) from lineal stimulus-cognition-response theories to closed-loop theories that model behavior as feeding back to sensory input via the environment, and (c) from theories that “chunk” responses to theories that acknowledge the continuous, dynamic nature of behavior. A closely related shift in methodology would involve studies that attempt to model each individual's performance as a continuous and dynamic activity within a closed-loop process. We explain how this shift can be made within a single framework—perceptual control theory (PCT)—that regards behavior as the control of perceptual input. We report evidence of multiple replication using this approach within visual tracking, and go on to demonstrate in practical research terms how the same overarching principle can guide research across diverse domains of psychology and the behavioral sciences, promoting their coherent integration. We describe ways to address current challenges to this approach and provide recommendations for how researchers can manage the transition
