The Dog that Finally Barked:England as an Emerging Political Community

This report presents evidence which suggests the emergence of a new kind of Anglo-British identity in which the English component is increasingly the primary source of attachment for English people. It also suggests that English identity is becoming more politicised: that is, the more English a person feels, the more likely they are to believe that the current structure of the UK is unfair and to support a particularly English dimension to the governance of England

Investigative Research Projects for Students in Science: The State of the Field and a Research Agenda

One of the ways in which students can be taught science is by doing science, the intention being to help students understand the nature, processes, and methods of science. Investigative research projects may be used in an attempt to reflect some aspects of science more authentically than other teaching and learning approaches, such as confirmatory practical activities and teacher demonstrations. In this article, we are interested in the affordances of investigative research projects where students, either individually or collaboratively, undertake original research. We provide a critical rather than a systematic review of the field. We begin by examining the literature on the aims of science education, and how science is taught in schools, before specifically turning to investigative research projects. We examine how such projects are typically undertaken before reviewing their aims and, in more detail, the consequences for students of undertaking such projects. We conclude that we need social science research studies that make explicit the possible benefits of investigative research projects in science. Such studies should have adequate control groups that look at the long-term consequences of such projects not only by collecting delayed data from participants, but by following them longitudinally to see whether such projects make any difference to participants’ subsequent education and career destinations. We also conclude that there is too often a tendency for investigative research projects for students in science to ignore the reasons why scientists work in particular areas and to assume that once a written report of the research has been authored, the work is done. We therefore, while being positive about the potential for investigative research projects, make specific recommendations as to how greater authenticity might result from students undertaking such projects

Investigative school research projects in biology: Effects on students

Science education is sometimes orientated around students learning science by doing science. Investigative research projects may be intended to reflect some aspects of science more authentically than other teaching and learning approaches, such as confirmatory practical activities and teacher demonstrations. What remains under-researched is what the effects on students are as a result of undertaking such projects. In this study we collected data from students who were participating in investigative research projects. Our research question is ‘How do secondary school students participating in a biology research project see science and themselves in relation to it?’. Twelve 12-18 year-olds who were undertaking biology research projects in England participated in 1:1 interviews in 2021. There was an association between the participants’ motivation for engaging with the investigative research project and their science identities, with many of them articulating that the project provided them with an “authentic” experience of what “real scientists” do. Participants were nearly always positive about taking part in a research project; this was particularly the case for those students who presented their findings at a conference, where presenters received feedback from peers and members of the science community. For some of the participants, engaging in an investigative research project afforded them opportunities not only to develop their scientific inquiry skills but to gain a deeper understanding of the epistemological dimensions of science and its connection with historical, cultural and social values. This greater appreciation and insight into the nature of science increased their science-related career aspirations

Diffusion in a generalized Rubinstein-Duke model of electrophoresis with kinematic disorder

Using a generalized Rubinstein-Duke model we prove rigorously that kinematic disorder leaves the prediction of standard reptation theory for the scaling of the diffusion constant in the limit for long polymer chains $D \propto L^{-2}$ unaffected. Based on an analytical calculation as well as Monte Carlo simulations we predict kinematic disorder to affect the center of mass diffusion constant of an entangled polymer in the limit for long chains by the same factor as single particle diffusion in a random barrier model.Comment: 29 pages, 3 figures, submitted to PR

House rules: the collaborative nature of policy in domestic networks

We draw on ethnographic studies to understand the collaborative nature of network policies or rules in domestic settings. We outline the technical nature of network policy in enterprise domains and how this contrasts with the social or collaborative nature of rules in everyday life. We then consider the deployment of network control and policy system interfaces in domestic settings, highlighting the ways in which household members collaboratively exploited these to support network governance. Our results suggest that an important feature of network policy in domestic contexts is that rules about network activity are shaped by and answerable to the moral reasoning that governs domestic life. This reframes our understanding of how rules are oriented to and used in the home and has significant implications for the design of home network policy systems

Performance assessment of a NaI(Tl) gamma counter for PET applications with methods for improved quantitative accuracy and greater standardization

BACKGROUND: Although NaI(Tl) gamma counters play an important role in many quantitative positron emission tomography (PET) protocols, their calibration for positron-emitting samples has not been standardized across imaging sites. In this study, we characterized the operational range of a gamma counter specifically for positron-emitting radionuclides, and we assessed the role of traceable (68)Ge/(68)Ga sources for standardizing system calibration. METHODS: A NaI(Tl) gamma counter was characterized with respect to count rate performance, adequacy of detector shielding, system stability, and sample volume effects using positron-emitting radionuclides (409- to 613-keV energy window). System efficiency was measured using (18)F and compared with corresponding data obtained using a long-lived (68)Ge/(68)Ga source that was implicitly traceable to a national standard. RESULTS: One percent count loss was measured at 450 × 10(3) counts per minute. Penetration of the detector shielding by 511-keV photons gave rise to a negligible background count rate. System stability tests showed a coefficient of variation of 0.13% over 100 days. For a sample volume of 4 mL, the efficiencies relative to those at 0.1 mL were 0.96, 0.94, 0.91, 0.78, and 0.72 for (11)C, (18)F, (125)I, (99m)Tc, and (51)Cr, respectively. The efficiency of a traceable (68)Ge/(68)Ga source was 30.1% ± 0.07% and was found to be in close agreement with the efficiency for (18)F after consideration of the different positron fractions. CONCLUSIONS: Long-lived (68)Ge/(68)Ga reference sources, implicitly traceable to a national metrology institute, can aid standardization of gamma counter calibration for (18)F. A characteristic feature of positron emitters meant that accurate calibration could be maintained over a wide range of sample volumes by using a narrow energy window centered on the 511-keV peak

The Problem with Big Data: Operating on Smaller Datasets to Bridge the Implementation Gap

Big datasets have the potential to revolutionize public health. However, there is a mismatch between the political and scientific optimism surrounding big data and the public’s perception of its benefit. We suggest a systematic and concerted emphasis on developing models derived from smaller datasets to illustrate to the public how big data can produce tangible benefits in the long term. In order to highlight the immediate value of a small data approach, we produced a proof-of-concept model predicting hospital length of stay. The results demonstrate that existing small datasets can be used to create models that generate a reasonable prediction, facilitating health-care delivery. We propose that greater attention (and funding) needs to be directed toward the utilization of existing information resources in parallel with current efforts to create and exploit “big data.

Aggregation and Representation in the European Parliament Party Groups

While members of the European Parliament are elected in national constituencies, their votes are determined by the aggregation of MEPs in multinational party groups. The uncoordinated aggregation of national party programmes in multinational EP party groups challenges theories of representation based on national parties and parliaments. This article provides a theoretical means of understanding representation by linking the aggregation of dozens of national party programmes in different EP party groups to the aggregation of groups to produce the parliamentary majority needed to enact policies. Drawing on an original data source of national party programmes, the EU Profiler, the article shows that the EP majorities created by aggregating MEP votes in party groups are best explained by cartel theories. These give priority to strengthening the EP’s collective capacity to enact policies rather than voting in accord with the programmes they were nationally elected to represent
