description: New observations of 16 dwarf elliptical galaxies in the Virgo Cluster indicate that at least seven dEs have significant velocity gradients along their optical major axis, with typical rotation amplitudes of 20-30 km/s. Of the remaining nine galaxies in this sample, 6 have velocity gradients less than 20 km/s kpc^{-1} while the other 3 observations had too low of a signal--to--noise ratio to determine an accurate velocity gradient. Typical velocity dispersions for these galaxies are ~44 +/- 5 km/s, indicating that rotation can be a significant component of the stellar dynamics of Virgo dEs. When corrected for the limited spatial extent of the spectral data, the rotation amplitudes of the rotating dEs are comparable to those of similar brightness dIs. Evidence for a relationship between the rotation amplitude and galaxy luminosity is found, and, in fact, agrees well with the Tully-Fisher relation. The similarity in the scaling relations of dIs and dEs implies that it is unlikely that dEs evolve from significantly more luminous galaxies. These observations reaffirm the possibility that some cluster dwarf elliptical galaxies may be formed when the neutral gaseous medium is stripped from dwarf irregular galaxies in the cluster environment. We hypothesize that several different mechanisms are involved in the creation of the overall population of dE galaxies, and that stripping of infalling dIs may be the dominant process in the creation of dEs in clusters like Virgo.

description: We present UBVRI surface photometry for 16 dwarf elliptical galaxies in the Virgo Cluster with previously measured kinematic properties. The global optical colors are red, with median values for the sample of 0.24 +/- 0.03 in (U-B), 0.77 +/- 0.02 in (B-V), and 1.02 +/- 0.03 in (V-I). We recover the well known color-magnitude relation for cluster galaxies, but find no significant difference in dominant stellar population between rotating and non-rotating dwarf elliptical galaxies; the average age of the dominant stellar population is 5-7 Gyr in all 16 galaxies in this sample. Analysis of optical spectra confirm these age estimates and indicate Fe and Mg abundances in the range of 1/20th to 1/3 of solar, as expected for low luminosity galaxies. Based on Lick indices and simple stellar population models, the derived [alpha/Fe] ratios are sub-solar to solar, indicating a more gradual chemical enrichment history for dEs as compared to giant elliptical galaxies in the Virgo Cluster. These observations confirm the marked difference in stellar population and stellar distribution between dwarf and giant elliptical galaxies and further substantiate the need for alternative evolutionary scenarios for the lowest mass cluster galaxies. We argue that it is likely that several different physical mechanisms played a significant role in the production of the Virgo cluster dE galaxies including in situ formation, infall of dEs that were once part of Local Group analogs, and transformation of dwarf irregular galaxies by the cluster environment. The observations support the hypothesis that a large fraction of the Virgo cluster dEs are formed by ram pressure stripping of gas from infalling dIs.

description: We report calculations of B_K using two flavours of dynamical clover-improved Wilson lattice fermions and look for dependence on the dynamical quark mass at fixed lattice spacing. We see some evidence for dynamical quark effects. In particular B_K decreases as the sea quark masses are reduced towards the up/down quark mass. Our meson masses are quite heavy and a firm prediction of B_K is a task for future simulations.

title: Cracking The Code: Accreditation Of Prior Experiential Learning And The Discourses Of Higher Education
Creators: name: Peters, Helen
Publisher: name: The Open University
Year: 2004

description: This thesis seeks to examine the process of Accreditation of Prior Experiential Learning (APEL) in a university in the CK, in order to discover how it is working. The starting premise is that APEL generally is not fulfilling expectations in terms of either benefiting students or widening participation. Nor has it taken on the emancipatory role, attributed to it by some of its promoters, of opening up institutions of higher education in terms of the control of knowledge and the recognition of knowledge gained in contexts outside the academy. The approach taken to the research is qualitative, focusing on a single institution in some detail, with the researcher central to the process. Data take the form of documentation produced by the institution, taped seminars, texts produced by students and interviews with lecturers and students. All data are defined as texts and are analysed using Critical Discourse Analysis and Systemic Functional Linguistics. The conclusions find that the discoursal practices of the academy and the social structures they represent and create constitute a constraint on the potential of APEL as an instrument for broadening the recognition of different types and sources of knowledge. Different approaches to assessment for APEL are proposed, drawing on experience and theory developed elsewhere.

description: We analyze changes in volume and structure of Polish trade with pigs and pork in the years 2004-2013. We are interested in absolute as well as in relative changes, which make it possible to compare the position of Poland with the positions of differently developed countries as well as of selected Member States of the EU. We concentrate on export as our main goal is to analyze changes of Poland’s position in the world market, but we do not resign on analysis of import as complementary to export. We use statistical data from the database Comtrade (WITS). We prove, that in the years 2004-2014 Poland’s shares in global trade with pigs and pork has changed a lot. Poland is leasing the international market of pigs relaying more and more on their import. At the same time it is holding its position on the pork market specializing in relatively more technologically advanced products. / Synopsis.

Koncentrujemy uwagę na eksporcie, gdyż głównym celem opracowania jest analiza zmian pozycji Polski na rynku światowym, jednak nie rezygnujemy z badania importu. Dopełnia ono bowiem analizę udziału Polski w interesującym nas handlu. Posługujemy się danymi statystycznymi pochodzącymi z bazy Comtrade (WITS). Dowodzimy, że w latach 2004-2013 nastąpiły duże zmiany w udziale Polski w światowym handlu trzodą chlewną i wieprzowiną. Polska wycofuje się z rynku trzody chlewnej w coraz większym stopniu polegając na jej imporcie. Równocześnie utrzymuje ona wysoką pozycję na rynku produktów bardziej zaawansowanych technologicznie (wieprzowina).

description: Late blight caused by the fungus Phytophthora infestans is the most important disease of potato that can result in crop failure within a short period, if appropriate control measures are not adopted. Despite the introduction of chemical, biological and host resistance strategies over years for controlling the disease, severe losses still occur largely because the effectiveness of these approaches is variable and often short lived. So, the present study was taken up by integrating or combining these strategies to control the disease. The different management components viz., tuber dressing with Dimethomorph, soil amendment with Trichoderma Viride and FYM, and foliar application of SAR chemical benzothiadiazole (BTH) and fungicides Dimethomorph 50WP and Mancozeb75WP alone as well as in alternation with each other were integrated and evaluated on two different varieties of potato i.e susceptible cultivar Kufri Jyoti as well as on a moderately resistant variety Shalimar-1 planted at two different locations in Kashmir viz Shalimar and Yarikha separately during 2017 cropping season. The results revealed that all the treatments proved effective in reducing the late blight incidence and intensity in comparison to control. The treatment with foliar application with either dimethomorph 50 WP or mancozeb 75 WP alone or in alternation with each other +foliar spray of BTH+ soil amendment (FYM+ T.viride) exhibited least blight incidence, intensity and A value (AUDPC) with concomitant higher yield gains and improvement in tuber grades followed by treatments which received foliar application of BTH +soil amendment (FYM + T. Viride) or soil amendment alone, whereas highest disease intensity, incidence and A value (AUDPC)with lowest yield and inferior grade tubers were observed in case of untreated control. Moderately resistant variety Shalimar 1 exhibited very less disease intensity, incidence and ‘A’value compared to susceptible cultivar kufri jyothi when provided with similar treatments at both locations i.e Shalimar and Yarikha in Kashmir.

description: We apply a quark combination model with equal-velocity combination (EVC) approximation to study the elliptic flow ($v_{2}$) of hadrons in heavy-ion collisions in a wide collision energy range ($\sqrt{s_{NN}}=$ 27 - 5020 GeV). Utilizing the simple relationship between $v_{2}$ of hadrons and those of quarks under EVC, we find that $v_{2}$ of up/down quarks obtained by experimental data of proton is consistent with that obtained by data of $Λ$ and $Ξ$. $v_{2}$ of strange quarks obtained by data of $Ω$ is consistent with that obtained by data of $Λ$ and $Ξ$, and at RHIC energies it is also consistent with that obtained by data of $ϕ$. This means that $v_{2}$ of these hadrons have a common quark-level source. Using data of $D^0$, we obtain $v_{2}$ of charm quarks with $p_T\lesssim 6$ GeV/c. We find that under EVC charm quark dominates $v_{2}$ of $D$ mesons at low $p_{T}$ but light-flavor quarks significantly contribute to $v_{2}$ of $D$ mesons in the range $3\lesssim p_{T}\lesssim8$ GeV/c. We predict $v_{2}$ of charmed baryons $Λ_{c}^{+}$ and $Ξ_{c}^{0}$ which show a significant enhancement at intermediate $p_{T}$ due to the double contribution of light-flavor quarks. The properties of the obtained quark $v_{2}$ under EVC are studied and a regularity for $v_{2}$ of quarks as the function of $p_{T}/m$ is found.

title: Student Retention: One College's Attempt To Deal With The Problem In The Light Of Recent Government Policy 1999-2002
Creators: name: Palmer, John Charles Joseph
Publisher: name: The Open University
Year: 2004

description: This study investigates the reasons for, and potential managerial solutions to, the problem of high rates of student drop-out on full-time Humanities programmes at a further education (FE) college in a disadvantaged area of the North of England. As rates of student withdrawal have attracted the attention of policy makers, the research examines the assumptions which shaped the decision to define drop-out as a problem and to use funding mechanisms and the inspection process to penalise colleges which experience higher than average rates of drop-out. A review of the literature indicated that during the last ten years the dominant assumption that influenced the policy response to student drop-out appears to have been informed by research positioned within the school effectiveness paradigm. In particular, the study by Martinez (1995) and Davies (1997) reinforced the view that withdrawal is caused primarily by deficiencies in the quality of teaching and student support. An evaluation of their findings provided a starting point for the investigation into student drop-out at the case-study college. Having identified serious flaws in the validity of their findings, this investigation, which used a range of research methods, including biographical interviews with students, suggests that withdrawal is caused by a complex combination of factors which are located mainly outside the college. Nevertheless, the study points to the delicate interaction between college-based and external influences on both leaving and completing. Consequently, a number of opportunities to improve college-based practices were identified and incorporated into a series of tentative recommendations for a managerial response to the issue of drop-out. The investigation concluded with an examination of the messages which could be drawn from the findings by those who shape national policy. It contends that the continuation of the current policy is likely to be counterproductive in terms of retention improvement and could also undermine other priorities such as widening participation.
Fragmentation in H->b bbar Processes

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: I study bottom quark fragmentation in the Standard Model Higgs decay H->b bbar, within the framework of perturbative fragmentation functions. I resum large collinear logarithms ln(m_H^2/m_b^2) in the next-to-leading logarithmic (NLL) approximation, using the DGLAP evolution equations. Soft contributions to the MSbar coefficient function and to the initial condition of the perturbative fragmentation function are resummed to NLL accuracy as well. The implementation of collinear and soft resummation has a relevant impact on the b energy spectrum, which exhibits a milder dependence on factorization and renormalization scales and on the Higgs mass. I present some predictions on the energy distribution of b-flavoured hadrons in Higgs decay, making use of data from LEP and SLD experiments to fit a few hadronization models. I also compare the phenomenological results yielded by a few processes recently provided with NLL collinear and soft resummations.

description: We perform a detailed parameter estimation study of binary black hole merger events reported in Zackay et al. and Venumadhav et al.. These are some of the faintest signals reported so far, and hence, relative to the loud events in the GWTC-1 catalog, the data should have lesser constraining power on their intrinsic parameters. Hence we examine the robustness of parameter inference to choices made in the analysis, as well as any potential systematics. We check the impact of different methods of estimating the noise power spectral density, different waveform models, and different priors for the compact object spins. For most of the events, the resulting differences in the inferred values of the parameters are much smaller than their statistical uncertainties. The estimation of the effective spin parameter $χ_{\mathrm{eff}}$, i.e. the projection of the mass-weighted total spin along the angular momentum, can be sensitive to analysis choices for two of the sources with the largest effective spin magnitudes, GW151216 and GW170403. The primary differences arise from using a 3D isotropic spin prior: the tails of the posterior distributions should be interpreted with care and due consideration of the other data analysis choices.

description: We present the first step towards the estimation of finite volume effects in heavy-light meson systems using heavy meson chiral perturbation theory. We demonstrate that these effects can be amplified in both light-quark and heavy-quark mass extrapolations (interpolations) in lattice calculations. As an explicit example, we perform a one-loop calculation for the neutral B meson mixing system and show that finite volume effects, which can be comparable with currently quoted errors, are not negligible in both quenched and partially quenched QCD.

Why managers don’t always do the right thing when delivering bad news : the effect of empathy, self-esteem, emotional intelligence, moral reasoning, and moral identity
Creators: name: Patient, David Leonard
Publisher: name: University of British Columbia
Year: 2010

description: Previous research shows that some managers do not deliver bad news in ways deemed interactionally fair (with dignity, respect, and adequate explanations). In this dissertation I explore whether specific individual characteristics predict the tendency to deliver bad news in ways regarded as interactionally (un)fair: the communicator’s empathy, self-esteem, moral development, emotional intelligence, and moral identity. In Study 1, 173 practicing managers responded to a scenario task in which a layoff was to be communicated and their written messages were coded for interactional justice. Results showed that empathic concern, moral development, and strategic emotional intelligence each individually predicted interactional justice. However, these relationships were not significant when all of the predictors and proposed interactions were included. Moral development moderated the relationship between empathic concern and interactional justice. In Study 2, 81 students provided face-to-face feedback containing negative news to a confederate, and the videotaped feedback was coded for interactional justice. In Study 2, empathic induction was manipulated and moral identity was primed. Results showed that empathic induction increased interactional justice. Further, a significant three-way interaction showed that when moral identity was high, moral development moderated the effect of the empathic induction on interactional justice. Specifically, the interactional fairness of high (versus low) moral development communicators was lower in the control condition and increased by the empathic induction, whereas the interactional fairness of low moral development communicators was not affected by the empathic induction.

description: We propose and analyze a new type of a resonator in an annular geometry which is based on a single defect surrounded by radial Bragg reflectors on both sides. We show that the conditions for efficient mode confinement are different from those of the conventional Bragg waveguiding in a rectangular geometry. A simple and intuitive approach to the design of optimal radial Bragg reflectors is proposed and employed, yielding chirped gratings. Small bending radii and strong control over the resonator dispersion are possible by the Bragg confinement. A design compromise between large Free Spectral Range (FSR) requirements and fabrication tolerances is suggested.

title: Speaking The Subject: A Discourse Analysis Of Undergraduate Seminar Practice
Creators: name: Goddard, Sharon
Publisher: name: The Open University
Year: 2003

description: This dissertation explores talk in an undergraduate seminar context. Research design was informed by an interpretive, ethnomethodological approach to understanding talk as a situated activity. A series of student-led seminars were audio recorded; students and staff were interviewed and post-seminar group debriefing sessions were held. The data was subsequently transcribed and analysed using a functional systemic linguistics and discourse analysis approach. Analysis identified structural and linguistic elements of seminar talk and links between language, identity, power and status was explored through an analysis of the discursive processes at work in the seminar events.An heuristic model of the seminar as a socio-pedagogic space, a site of hegemonic struggle, was used to aid concept development.

 A number of issues emerged within an interpretative framework of the cognitive, interpersonal and textual elements of seminar talk. In the analysis of the textual meta-function of seminars, how complexity is achieved and how conversational moves are patterned, seminars appear to constitute a hybrid talk variety, a highly unusual textual form in which participants need to learn how to participate.

 Tensions were found between the social and the cognitive elements of seminars. Student participants tend to use the seminar to achieve social effects, identifying and maintaining interpersonal relationships. The collaborative discourse strategies they employ constrain other opportunities for achieving educational outcomes. The learning which does take place is more likely to be related to personal and skills development than to learning about the academic subject. Students deployed a range of heteroglossic discursive strategies to practice their skills in forming ideas, marshalling evidence and constructing argument. The discursive practices of seminar events foreground tensions between socially situated identities.

 The research identifies a number of areas for improving practice including: enhanced specification of seminar processes and outcomes; embedding opportunities for preparation and critical reflection; teaching the subject of communication and foregrounding understandings of the discursive practices at work in seminars so as to empower individual learners.

description: We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulations. We consider a population destined for extinction in the absence of mutants, which can only survive if mutants sufficiently adapted to the new environment arise and fix. We show that mutants that appear later during the environment deterioration have a higher probability to fix. The rescue probability of the population increases with a sigmoidal shape when the product of the carrying capacity and of the mutation probability increases. Furthermore, we find that rescue becomes more likely for smaller population sizes and/or mutation probabilities if the environment degradation is slower, which illustrates the key impact of the rapidity of environment degradation on the fate of a population. We also show that our main conclusions are robust across various types of adaptive mutants, including specialist and generalist ones, as well as mutants modeling antimicrobial resistance evolution. We further express the average time of appearance of the mutants that do rescue the population and the average extinction time of those that do not. Our methods can be applied to other situations with continuously variable fitnesses and population sizes, and our analytical predictions are valid in the weak-to-moderate mutation regime.

description: This study investigated the influence of self-efficacy on the academic performance of the Grade 12 Senior High School students at the St. Paul College of Bocaue. The findings of the study concluded that the level of the self-efficacy of the respondents was high. Likewise, the findings suggested that the students are resilient and determined in the face of setbacks, feel assured that they will be able to learn the classroom discussion, and excel on their assessment, and they tend to be more intrinsically motivated to learn new knowledge. Furthermore, the computed linear regression analysis results revealed that self-efficacy does not significantly affect the Senior High School students’ academic performance. This suggests that even if the students have a high level of self-efficacy, it doesn’t influence their academic performance in class. However, it doesn’t mean that the school should not give importance to develop the students’ self-efficacy. Hence, it is suggested that the school should continue its academic programs that will continuously develop the student’s well-being in the process of acquiring relevant experiences and skills in the school.

description: The growth rates and chemical ordering of ferroelectric alloys are studied with kinetic Monte Carlo (KMC) simulations using an electrostatic model with long-range Coulomb interactions, as a function of temperature, chemical composition, and substrate orientation. Crystal growth is characterized by thermodynamic processes involving adsorption and evaporation, with solid-on-solid restrictions and excluding diffusion. A KMC algorithm is formulated to simulate this model efficiently in the presence of long-range interactions. Simulations were carried out on Ba(Mg_{1/3}Nb_{2/3})O_3 (BMN) type materials. Compared to the simple rocksalt ordered structures, ordered BMN grows only at very low temperatures and only under finely tuned conditions. For materials with tetravalent compositions, such as (1-x)Ba(Mg_{1/3}Nb_{2/3})O_3 + xBaZrO_3 (BMN-BZ), the model does not incorporate tetravalent ions at low-temperature, exhibiting a phase-separated ground state instead. At higher temperatures, tetravalent ions can be incorporated, but the resulting crystals show no chemical ordering in the absence of diffusive mechanisms.

A recent addition to the physics curriculum at Florida State University, "The Physics of Stars", sparked quite a few students' interests in the subject matter involving stellar structure. This, coupled with "Stars and Statistical Physics" by Balian and Blaizot and "Neutron Stars for Undergraduates" by Silbar and Reddy, is the cornerstone of this small research group who tackled solving the structure equations for compact objects in the Summer of 2004. Through the use of a simple finite-difference algorithm coupled to Microsoft Excel and Maple, solutions to the equations for stellar structure are presented in the Newtonian regime appropriate to the physics of white dwarf stars.

The Psychology and Neuroeconomics of Pro-Environmental Behavior

description: For several years, society has faced climate change catastrophes ranging from wildfires to rising sea levels. To combat these effects, researchers have focused on creating technological and societal shifts. However, understanding and influencing an individual's behavior is often overlooked but can provide a benefit. Pro-environmental behavior, or PEB, is an individual’s tendency to consciously reduce negative environmental impacts while improving environmental conditions. Research has shown the advantages of using behavioral findings and neuroeconomics to deepen our understanding of PEB to promote and nudge,or influence consumers subconsciously, to act with PEB. Though this interdisciplinary approach to climate change is relatively new and unexplored, research reveals that it is a growing field. This literature review provides an overview of PEB in the fields of psychology, neuroscience, and marketing. We first examine the psychological factors, such as personality and motivation, that influence PEB and pro-environmental attitudes (PEA). We then move to neuroscience findings based on an individual's brain size and brain activation when engaging in sustainable behavior. Lastly, the neuroscience findings are applied to construct efficient marketing techniques for firms to apply to consumers and promote sustainable behavior.

description: We discuss the implications that new magnetocaloric, thermal expansion and magnetostriction data in $α$-RuCl$_{3}$ single crystals have on its temperature-field phase diagram and uncover the magnetic-field dependence of an apparent energy gap structure $Δ(H)$ that evolves when the low temperature antiferromagnetic order is suppressed. We show that, depending on how the thermal expansion data is modeled, $Δ(H)$ can show a cubic field dependence and remain finite at zero field, consistent with the pure Kitaev model hosting itinerant Majorana fermions and localized $\mathbb{Z}_{2}$ fluxes. Our magnetocaloric effect data provides, below $1\,\mathrm{K}$, unambiguous evidence for dissipative phenomena at $H_{\mathrm{c}}$, smoking gun for a first order phase transition. Our results, on the other hand, show little support for a phase transition from a QSL to a polarized paramagnetic state above $H_{\mathrm{c}}$.
Consistent discretization and loop quantum geometry

description: We apply the ``consistent discretization'' approach to general relativity leaving the spatial slices continuous. The resulting theory is free of the diffeomorphism and Hamiltonian constraints, but one can impose the diffeomorphism constraint to reduce its space of solutions and the constraint is preserved exactly under the discrete evolution. One ends up with a theory that has as physical space what is usually considered the kinematical space of loop quantum geometry, given by diffeomorphism invariant spin networks endowed with appropriate rigorously defined diffeomorphism invariant measures and inner products. The dynamics can be implemented as a unitary transformation and the problem of time explicitly solved or at least reduced to as a numerical problem. We exhibit the technique explicitly in 2+1 dimensional gravity.

description: The forthcoming Laser Interferometer Space Antenna (LISA) will probe the population of coalescing massive black hole (MBH) binaries up to the onset of structure formation. Here we simulate the galactic-scale pairing of $\sim10^6 M_\odot$ MBHs in a typical, non-clumpy main-sequence galaxy embedded in a cosmological environment at $z = 7-6$. In order to increase our statistical sample, we adopt a strategy that allows us to follow the evolution of six secondary MBHs concomitantly. We find that the magnitude of the dynamical-friction induced torques is significantly smaller than that of the large-scale, stochastic gravitational torques arising from the perturbed and morphologically evolving galactic disc, suggesting that the standard dynamical friction treatment is inadequate for realistic galaxies at high redshift. The dynamical evolution of MBHs is very stochastic, and a variation in the initial orbital phase can lead to a drastically different time-scale for the inspiral. Most remarkably, the development of a galactic bar in the host system either significantly accelerates the inspiral by dragging a secondary MBH into the centre, or ultimately hinders the orbital decay by scattering the MBH in the galaxy outskirts. The latter occurs more rarely, suggesting that galactic bars overall promote MBH inspiral and binary coalescence. The orbital decay time can be an order of magnitude shorter than what would be predicted relying on dynamical friction alone. The stochasticity, and the important role of global torques, have crucial implications for the rates of MBH coalescences in the early Universe: both have to be accounted for when making predictions for the upcoming LISA observatory.

description: The thermal effects on the quark-gluon mixed condensate g, which is another chiral order parameter, are studied using the SU(3)c lattice QCD with the Kogut-Susskind fermion at the quenched level. We perform the accurate measurement of the mixed condensate as well as the quark condensate for 0MeV<=T<=500MeV. We observe the sharp decrease of both the condensates around T_c \simeq 280MeV, while the thermal effects below T_c are found to be weak. We also find that the ratio m_0^2 = g/ is almost independent of the temperature even in the very vicinity of T_c, which indicates that the two condensates have nontrivial similarity in the chiral behaviors. We also present the correlation between the condensates and the Polyakov loop to understand the vacuum structure of QCD.

title: The Validity And Reliability Of Value-Added And Target-Setting Procedures With Special Reference To Key Stage 3
Creators: name: Moody, Ian Robin
Publisher: name: The Open University

description: The validity of value-added systems of measurement is crucially dependent upon there being a demonstrably unambiguous relationship between the so-called baseline, or intake measures, and any subsequent measure of performance at a later stage. The reliability of such procedures is dependent on the relationships between these two measures being relatively stable over time. A number of questions arise with regard to both the validity and reliability of value-added procedures at any level in education, but this appears to be particularly problematic at Key Stage 3. Target-setting procedures usually employ value-added data as the basis for predicting future performance, and the validity and reliability of target-setting procedures is therefore also problematic. In a five-year longitudinal case study of one secondary comprehensive school, the validity of both of these procedures was investigated using quantitative and qualitative methods. The validity and reliability of Key Stage 2 data, and data from the NFER Cognitive Abilities Test (CAT), as baseline data for value-added procedures, was investigated using regression analysis. Wider perceptions of value-added procedures were opened up using detailed interviews with a representative cross-section of teachers. Target-setting procedures were investigated by analysing numerical performance data in curriculum areas, by the use of questionnaires to students, staff and parents, and by detailed interviews with a representative sample of students. The results of the investigation suggest that whilst value-added procedures have a high level of validity and reliability for Mathematics at Key Stage 3, this is less true for English and Science. For non-core subjects there appears to be no rational basis upon which value-added procedures can be used. Staff attitudes towards both value-added and target-setting were often quite ambivalent; those of students and parents were generally much more positive. A number of concerns emerged with regard to the ways in which such procedures appear to be distorting teaching and learning, producing a culture of performativity where learning is increasingly seen as a means to an end, rather than a worthwhile end in itself. These findings raise some fundamental questions about our philosophy of education, about accountability, and about the knowledge claims which are made as a result of such procedures.
A Particular Upper Expectation as Global Belief Model for Discrete-Time Finite-State Uncertain Processes

description: To model discrete-time finite-state uncertain processes, we argue for the use of a global belief model in the form of an upper expectation that is the most conservative one under a set of basic axioms. Our motivation for these axioms, which describe how local and global belief models should be related, is based on two possible interpretations for an upper expectation: a behavioural one similar to Walley's, and an interpretation in terms of upper envelopes of linear expectations. We show that the most conservative upper expectation satisfying our axioms, that is, our model of choice, coincides with a particular version of the game-theoretic upper expectation introduced by Shafer and Vovk. This has two important implications: it guarantees that there is a unique most conservative global belief model satisfying our axioms; and it shows that Shafer and Vovk's model can be given an axiomatic characterisation and thereby provides an alternative motivation for adopting this model, even outside their game-theoretic framework. Finally, we relate our model to the upper expectation resulting from a traditional measure-theoretic approach. We show that this measure-theoretic upper expectation also satisfies the proposed axioms, which implies that it is dominated by our model or, equivalently, the game-theoretic model. Moreover, if all local models are precise, all three models coincide.
