Enhancing spaceflight safety with UOS3 cubesat
Earth orbits are becoming increasingly congested. This will not only impact future space operations but also become a concern for the population on the ground; with more spacecraft being flown, more objects will re-enter the atmosphere in an uncontrolled fashion. Parts of these satellites can reach Earth surface and endanger the ground population (e.g. ROSAT or UARS satellites). A student-run project from the University of Southampton aims to build a 1U cubesat (approx. 10 by 10 by 10 cm satellite), which will gather data that will improve the accuracy of re-entry predictions. The cubesat will record and deliver its position and attitude during the orbital decay, thus providing validation data for re-entry prediction tools. This will reduce the risk to the ground population because more accurate prognoses will allow mitigation measures to be implemented in the areas at risk. The mission could also allow the risk of collision between spacecraft to be estimated more accurately thanks to improvement of the atmospheric models. This would give the decision makers more complete information to use, for instance, in collision avoidance manoeuvre plannin
Policy, Performativity and Partnership: an Ethical Leadership Perspective
This article identifies the need to think differently about educational partnerships in a changing and turbulent post compulsory policy environment in England. The policy and institutional contexts in which universities and colleges currently operate seem to be fuelling performativity at the expense of educational values. There appears to be a sharp interruption in the steady increase in educational partnerships as a vehicle for increasing and widening participation in higher education. We are witnessing a marked change in university / college relationships that appears to be a consequence of government calling a halt to increased participation in higher education, creating an increasingly competitive market for a more limited pool of student places. The implication that educational policy at the national level determines a particular pattern or mode of leadership decision making throughout an institution should however be resisted. Policy developments that challenge the moral precepts of education should not be allowed to determine how a leader acts, rather they should prompt actions that are truly educational, rooted in morality, and atached to identifiable educational values. Educational leaders have agency to resist restricted discourses in favour of ethical and principled change strategies that are a precondition for sustainable transformative partnerships in post compulsory education. University leaders in particular are called upon to use their considerable influence to resist narrow policy or managerial instrumentalism or performativity and embrace alternatives that are both educationally worthwhile and can enhance institutional resilience
Annual estimates of occupancy for bryophytes, lichens and invertebrates in the UK, 1970β2015
Here, we determine annual estimates of occupancy and species trends for 5,293 UK bryophytes, lichens, and invertebrates, providing national scale information on UK biodiversity change for 31 taxonomic groups for the time period 1970 to 2015. The dataset was produced through the application of a Bayesian occupancy modelling framework to species occurrence records supplied by 29 national recording schemes or societies (nβ=β24,118,549 records). In the UK, annual measures of species status from fine scale data (e.g. 1βΓβ1 km) had previously been limited to a few taxa for which structured monitoring data are available, mainly birds, butterflies, bats and a subset of moth species. By using an occupancy modelling framework designed for use with relatively low recording intensity data, we have been able to estimate species trends and generate annual estimates of occupancy for taxa where annual trend estimates and status were previously limited or unknown at this scale. These data broaden our knowledge of UK biodiversity and can be used to investigate variation in and drivers of biodiversity change
Plastic and Heritable Components of Phenotypic Variation in Nucella lapillus: An Assessment Using Reciprocal Transplant and Common Garden Experiments
Assessment of plastic and heritable components of phenotypic variation is crucial for understanding the evolution of adaptive character traits in heterogeneous environments. We assessed the above in relation to adaptive shell morphology of the rocky intertidal snail Nucella lapillus by reciprocal transplantation of snails between two shores differing in wave action and rearing snails of the same provenance in a common garden. Results were compared with those reported for similar experiments conducted elsewhere. Microsatellite variation indicated limited gene flow between the populations. Intrinsic growth rate was greater in exposed-site than sheltered-site snails, but the reverse was true of absolute growth rate, suggesting heritable compensation for reduced foraging opportunity at the exposed site. Shell morphology of reciprocal transplants partially converged through plasticity toward that of native snails. Shell morphology of F2s in the common garden partially retained characteristics of the P-generation, suggesting genetic control. A maternal effect was revealed by greater resemblance of F1s than F2s to the P-generation. The observed synergistic effects of plastic, maternal and genetic control of shell-shape may be expected to maximise fitness when environmental characteristics become unpredictable through dispersal

Generative potential and the business development manager
Purpose: The purpose of this paper is to contribute to the development of understanding of the social processes involved in business engagement and understanding of the role of knowledge transfer practitioners. It is also to provide the first outlines of a theoretical framework of business engagement between higher education institutions and business, through the lens of complexity theory. Design/methodology/approach: The paper draws on research that explored the actions of a group of actors within a university Business School as they attempted to develop a range of business engagement activities. The data were analysed using a narrative event sequence methodology designed to deal systematically with the relationship between events occurring over time. The events were linked into a progression to create temporal maps which provided the basis for data collection and conceptual analysis. Findings: A space of possibilities was created by participants in the faculty to engage with industry that was adjacent to the teaching and learning space. The adjacent space set out to provide the business development team different expectations they could exploit to generate new interactions beyond the boundaries of the teaching and learning space. It was for the business development team to exploit the generative potential of the adjacent space by creating emergent events which developed halting as a non-linear progression that juxtaposed extinction and emergent events. In their interactions the business development managers had continually to reconcile the tension between compliance and generative potential through use of individual judgement. Practical implications: In developing business engagement activity consideration should be given to the contradictory world the business development managers act within and the constraints they experience. Through the examination of the events, lessons can be learned that enhance the generative potential of the business development manager. Originality/value: The theoretical outline of this paper provides an initial framework within which to examine the role of the business development manager. Β© Emerald Group Publishing Limited
