Change and continuity in school practice: A study of the influences affecting secondary school teachers' work, and of the role of local and national policies within them
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis examines the impact of local and national education policies on teachers' practice in six secondary schools in two similar, non-contiguous, metropolitan authorities. Ten propositions on the relationship between policy and action were generated from a literature review and related to literature on school organisation and culture. Empirical data to test them were collected between September 1987 and July 1989, during the development of National Curriculum legislation and statutory instruments but prior to its implementation in secondary schools. Extended interviews were conducted with sixty-six teachers, the six Headteachers, and both Chief Inspectors. Detailed interview reports were confirmed as accurate with each interviewee.
National influences were found to be important, particularly public examination reforms. This was attributed to their public use as indicators of school effectiveness, and to teachers' own positions resting on their own examination success for legitimacy. Personal professional values led to the LEA and its officers being dismissed as insignificant: factors internal to the school were more important. Chief among these was teachers' relationships with their departmental colleagues, especially how their perception of their needs and obligations as teachers of particular subjects, with particular epistemologies, affected departmental opportunities as management units to influence individual practice and require conformity to external requirements. Relations with senior staff were also important, and how far informal networks of power and influence operated against the formal hierarchies. Lastly, personal professional values stressed classroom experience as the only satisfactory basis for offering direction or guidance to teachers. This view of the teacher as expert emphasised that teachers must ultimately have autonomy to decide how best to handle classroom situations, and not only downgraded LEA staff and teacher education as sources of assistance, but also worked to prevent teachers from acknowledging problems to their colleagues

Distributed Leadership: A Review of Literature
A review of empirical research studies of distributed leadership from public and private sector settings completed since 1995
Masticatory musculature of the African mole-rats (Rodentia: Bathyergidae)
The Bathyergidae, commonly known as blesmols or African mole-rats, is a family of rodents well-known for their subterranean lifestyle and tunnelling behaviour. Four of the five extant bathyergid genera (Cryptomys, Fukomys, Georychus and Heliophobius) are chisel-tooth diggers, that is they dig through soil with their enlarged incisors, whereas the remaining genus (Bathyergus) is a scratch-digger, only using its forelimbs for burrowing. Heterocephalus glaber, the naked mole-rat, is also a chisel-tooth digger and was until recently included within the Bathyergidae (as the most basally branching genus), but has now been placed by some researchers into its own family, the Heterocephalidae. Given the importance of the masticatory apparatus in habitat construction in this group, knowledge and understanding of the morphology and arrangement of the jaw-closing muscles in Bathyergidae is vital for future functional analyses. Here, we use diffusible iodine-based contrast-enhanced microCT to reveal and describe the muscles of mastication in representative specimens of each genus of bathyergid mole-rat and to compare them to the previously described musculature of the naked mole-rat. In all bathyergids, as in all rodents, the masseter muscle is the most dominant component of the masticatory musculature. However, the temporalis is also a relatively large muscle, a condition normally associated with sciuromorphous rodents. Unlike their hystricomorphous relatives, the bathyergids do not show an extension of the masseter through the infraorbital foramen on to the rostrum (other than a very slight protrusion in Cryptomys and Fukomys). Thus, morphologically, bathyergids are protrogomorphous, although this is thought to be secondarily derived rather than retained from ancestral rodents. Overall, the relative proportions of the jaw-closing muscles were found to be fairly consistent between genera except in Bathyergus, which was found to have an enlarged superficial masseter and relatively smaller pterygoid muscles. It is concluded that these differences may be a reflection of the behaviour of Bathyergus which, uniquely in the family, does not use its incisors for digging
Net Yield Efficiency:Comparing Salad and Vegetable Waste between Community Supported Agriculture and Supermarkets in the UK
Food security is high on the global agenda. Two factors make it particularly pressing: the continuing rise in the global population, and the failure to adequately feed the current one. An area that has been the focus of much recent attention has been food waste; the Food and Agriculture Organization of the United Nations (FAO) estimates that as much as a third of all food is lost or wasted. This paper argues that by taking a food system approach that accounts for yields as well as loss and waste in distribution and consumption, we can compare the contribution of different food systems to food security. A novel concept of “net yield efficiency” (NYE) is introduced that accounts for this. We present an illustrative case study of the levels of fresh vegetable and salad waste in the supermarket-controlled food system compared with a community supported agriculture (CSA) scheme. This case study explores whether the CSA and its members are less wasteful than the supermarket system. The study found that when all stages of the food system were measured for waste, the CSA dramatically outperformed the supermarket system, wasting only 6.71% by weight compared to 40.7–47.7%. Even accounting for difficulties in estimating waste, the findings underline the differences between these systems. On this basis, the paper argues that the NYE measure provides a more accurate picture of food system performance than current measures, which tend to focus on yield alone
Energetic Benefits of Sociality Offset the Costs of Parasitism in a Cooperative Mammal
We thank the owners for access to their property for animal capture and KwaZulu-Natal Nature Conservation Service for issuing the capture permit.

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.Peer reviewedPublisher PD
Effects of cortisol administration on cooperative behavior in meerkat helpers
Experimental administration of stress hormones to meerkat helpers does not affect their contributions to cooperative activities. Previous work on cooperative breeders suggested that levels of stress hormones are related to helping behavior. We tested this experimentally by injecting meerkat helpers with cortisol, whilst matched controls received a saline injection. This did not lead to changes in cooperative behaviour, but induced females, and not males, to spend more time near pups and less time foragin
Judging the impact of leadership-development activities on school practice
The nature and effectiveness of professional-development activities should be judged in a way that takes account of
both the achievement of intended outcomes and the unintended consequences that may result. Our research project set out to create a robust approach that school staff members could use to assess the impact of
professional-development programs on leadership and management practice without being constrained in this judgment by the stated aims of the program. In the process,
we identified a number of factors and requirements relevant to a wider audience than that concerned with the development of leadership and management in England.
Such an assessment has to rest upon a clear understanding of educational leadership,a clearly articulated model of practice, and a clear model of potential forms of impact.
Such foundations, suitably adapted to the subject being addressed, are appropriate for assessing all teacher professional development
