Changing policy priorities for sport in England: the emergence of elite sport development as a key policy concern

This paper reviews the emergence of ‘sport’ as a sector of public policy interest from the 1960s to 2002. Central to the paper is the manifestation of ‘elite sport development’ as a key policy concern from the mid‐1990s onwards. While the emergence of elite sport policy objectives is the focus, the increased activity around sport at regional and sub‐regional levels in England also requires attention. The paper's theoretical argument is that, in large part, the effect of policy is primarily discursive; it changes the possibilities we have for thinking ‘otherwise’. In this respect, the discursive construction of sport policy is problematized. Here, the literature addressing ‘policy as discourse’ and, more specifically, that which analyses the ‘discursive strategies’ shaping school sport and physical education policy is helpful in sensitizing us to the inherent power relations hidden within the contours of sport policy debates. This analysis leads to questions surrounding opportunities for ‘alternative voices’ within a context of discursive activity that privileges elite performance. In this regard, the study concludes by offering avenues of future research for the analysis of sport policy processes.
Investigation of the mass-charge composition of cathode material ions in the low-current vacuum arc plasma

Charge-state distribution of cathode material ions in the vacuum arc plasma was investigated via the Thomson spectrometer with automated recording and processing of spectrograms. Arc discharge current was varied in range 1.7-110 A. There was obtained the dependence of the mass-charge composition of the ions on the current pulse amplitude. Average charge number for copper ions decreased with arc current decreasing from 2 at the 100-150 A value of current amplitude to 1.55 at the 1.7 A value. Generally, mean charge was affected by increasing of the Cu+ fraction and decreasing of the fractions of higher charge-state ions with decreasing of the current pulse amplitude.
Content Delivery Latency of Caching Strategies for Information-Centric IoT

In-network caching is a central aspect of Information-Centric Networking (ICN). It enables the rapid distribution of content across the network, alleviating strain on content producers and reducing content delivery latencies. ICN has emerged as a promising candidate for use in the Internet of Things (IoT). However, IoT devices operate under severe constraints, most notably limited memory. This means that nodes cannot indiscriminately cache all content; instead, there is a need for a caching strategy that decides what content to cache. Furthermore, many applications in the IoT space are timesensitive; therefore, finding a caching strategy that minimises the latency between content request and delivery is desirable. In this paper, we evaluate a number of ICN caching strategies in regards to latency and hop count reduction using IoT devices in a physical testbed. We find that the topology of the network, and thus the routing algorithm used to generate forwarding information, has a significant impact on the performance of a given caching strategy. To the best of our knowledge, this is the first study that focuses on latency effects in ICN-IoT caching while using real IoT hardware, and the first to explicitly discuss the link between routing algorithm, network topology, and caching effects.
7.1 keV sterile neutrino dark matter constraints from a deep Chandra X-ray observation of the Galactic bulge Limiting Window

Context. An unidentified emission line at 3.55 keV was recently detected in X-ray spectra of clusters of galaxies. The line has been discussed as a possible decay signature of 7.1 keV sterile neutrinos, which have been proposed as a dark matter (DM) candidate. Aims. We aim to further constrain the line strength and its implied mixing angle under the assumption that all DM is made of sterile neutrinos. Methods. The X-ray observations of the Limiting Window (LW) towards the Galactic bulge (GB) offer a unique dataset for exploring DM lines. We characterise the systematic uncertainties of the observation and the fitted models with simulated X-ray spectra. In addition, we discuss uncertainties of indirect DM column density constraints towards the GB to understand systematic uncertainties in the assumed DM mass in the field of view of the observation. Results. We find tight constraints on the allowed flux for an additional line at 3.55 keV with a positive (∼1.5σ) best fit value FX3.55 keV ≈ (4.5 ± 3.5) × 10−7 cts cm−2 s−1. This would translate into a mixing angle of sin2(2Θ) ≈ (2.3 ± 1.8) × 10−11 which, while consistent with some recent results, is in tension with earlier detections. Conclusions. We used a very deep dataset with well understood systematic uncertainties to derive tight constraints on the mixing angle of a 7.1 keV sterile neutrino DM candidate. The results highlight that the inner Milky Way will be a good target for DM searches with upcoming missions like eROSITA, XRISM, and ATHENA.
Universal behavior of connectivity properties in fractal percolation models

Partially motivated by the desire to better understand the connectivity phase transition in fractal percolation, we introduce and study a class of continuum fractal percolation models in dimension $d\geq2$. These include a scale invariant version of the classical (Poisson) Boolean model of stochastic geometry and (for $d=2$) the Brownian loop soup introduced by Lawler and Werner. The models lead to random fractal sets whose connectivity properties depend on a parameter $\lambda$. In this paper we mainly study the transition between a phase where the random fractal sets are totally disconnected and a phase where they contain connected components larger than one point. In particular, we show that there are connected components larger than one point at the unique value of $\lambda$ that separates the two phases (called the critical point). We prove that such a behavior occurs also in Mandelbrot's fractal percolation in all dimensions $d\geq2$. Our results show that it is a generic feature, independent of the dimension or the precise definition of the model, and is essentially a consequence of scale invariance alone. Furthermore, for $d=2$ we prove that the presence of connected components larger than one point implies the presence of a unique, unbounded, connected component.
Power Optimization for Energy Efficiency in Cell-Free Massive MIMO with ZF Receiver

In this paper, a pilot-contaminated uplink cell-free massive multiple-input multiple-output (mMIMO) system with zero-forcing (ZF) receiver is considered. Then this paper derives a novel lower-bound expression for uplink energy efficiency (EE), which enables us to propose a resource optimization problem to maximize the total EE. This considered power optimization scheme takes into account the quality-of-service (QoS) requirement, each user power constraint and power consumption. Specifically, the power consumption model includes circuit power, data transmission power and backhaul power. Since the proposed power control problem is non-convex, a novel path-following approximation algorithm is characterized to tackle this problem. Simulation results indicate that the proposed algorithm only needs a few iterations to converge. Moreover, compared with equal power control (EPC) scheme, our algorithm can significantly improve the total EE.
The Importance of Being First: Unique Characteristics of First Generation Community College Students

A survey of 5,037 applicants to 12 colleges in the University of Kentucky Community College System revealed that first-generation enrollees came from a unique socioeconomic background, were motivated by a different set of goals, and were constrained by a different set of limitations than those whose parents were college educated (based on cui-square analyses and t tests). No significant differences were detected, however, between first-generation and other students in their total hours earned and cumulative GPAs at the end of their first year attending a college in the system.
Cloning and nucleotide sequence of the Campylobacter jejuni gyrA gene and characterization of quinolone resistance mutations

The gyrA gene of Campylobacter jejuni UA580, which encodes the A subunit of DNA gyrase, was cloned and its nucleotide sequence was determined. An open reading frame of 2,589 nucleotides was identified, which could code for a polypeptide of 863 amino acids with a M(r) of 97 kDa. Both the nucleotide sequence and the putative amino acid sequence show ca. 50% identity with those of other gyrA genes from gram-positive and gram-negative bacteria. The locations of the gyrA gene on genome maps of both C. jejuni UA580 and Campylobacter coli UA417 were determined. Six nalidixic acid-resistant isolates of C. jejuni were shown to carry mutations in gyrA. Three clinical isolates had Thr-86-to-Ile substitutions. Three laboratory mutants had substitutions of Thr-86 to Ile, Asp-90 to Ala, and Ala-70 to Thr, respectively. The mutation at Thr-86, which is homologous to Ser-83 in Escherichia coli, was associated with high-level resistance to ciprofloxacin in C. jejuni.
Conformal Killing initial data

We find necessary and sufficient conditions ensuring that the vacuum development of an initial data set of the Einstein's field equations admits a conformal Killing vector. We refer to these conditions as conformal Killing initial data (CKID) and they extend the well-known Killing initial data that have been known for a long time. The procedure used to find the CKID is a classical argument, which is reviewed and presented in a form that may have an independent interest, based on the computation of a suitable propagation identity.
A dust and gas cavity in the disc around CQ Tau revealed by ALMA

The combination of high-resolution and sensitivity offered by ALMA is revolutionizing our understanding of protoplanetary discs, as their bulk gas and dust distributions can be studied independently. In this paper we present resolved ALMA observations of the continuum emission (λ = 1.3 mm) and CO isotopologues (^(12)CO, ^(13)CO, C^(18)O, J = 2 − 1) integrated intensity from the disc around the nearby (d = 162 pc), intermediate-mass (⁠M⋆=1.67M⊙⁠) pre-main-sequence star CQ Tau. The data show an inner depression in continuum and in both ^(13)CO and C^(18)O emission. We employ a thermo-chemical model of the disc reproducing both continuum and gas radial intensity profiles, together with the disc spectral energy distribution. The models show that a gas inner cavity with size between 15 and 25 au is needed to reproduce the data with a density depletion factor between ∼10^(−1) and ∼10^(−3). The radial profile of the distinct cavity in the dust continuum is described by a Gaussian ring centred at R_(dust) = 53au and with a width of σ = 13au. Three-dimensional gas and dust numerical simulations of a disc with an embedded planet at a separation from the central star of ∼20 au and with a mass of ∼6−9M_(Jup) reproduce qualitatively the gas and dust profiles of the CQ Tau disc. However, a one-planet model appears not to be able to reproduce the dust Gaussian density profile predicted using the thermo-chemical modeling.
Effect of rhBMP-2 dose on bone formation/maturation in a rat critical-size calvarial defect model.

BACKGROUND Application of recombinant human bone morphogenetic protein-2 (rhBMP-2) has been associated with significant adverse events in craniofacial settings, including swelling and seroma formation. Recent work has demonstrated an inverse relationship between bone formation/maturation and rhBMP-2 dose, frequency/severity of adverse events increasing with rising dose. OBJECTIVE The objective of this study was to determine the most effective dose for rhBMP-2 soak-loaded onto an absorbable collagen sponge (ACS) carrier for bone formation/maturation using an established defect model. METHODS One hundred sixty-eight outbred male Sprague-Dawley rats, age 11-13 weeks, weight 325-375 g randomized into seven groups of 24 subdivided into groups of eight, were used to provide radiographic and light microscopy observations of bone formation/maturation and aberrant healing events at 2, 4 and 8 weeks following application of rhBMP-2/ACS into critical-size, ø8-mm, through-through, calvarial osteotomy defects for a dose of 1.25, 2.5, 5.0, 10.0 and 20.0 μg rhBMP-2/defect, or serve as ACS or sham-surgery controls. RESULTS rhBMP-2 dosages ≥ 2.5 μg/defect showed histological defect closure >90% within 2 weeks, and complete resolution within 4 weeks. Adverse healing events including swelling, excessive bone formation or seroma formation could not be determined with certainty in this defect model. Notably ACS control sites showed complete defect closure at the 8-week healing interval. CONCLUSIONS rhBMP-2/ACS accelerates local bone formation in the rat critical-size through-through calvarial defect model once reaching an osteoinductive dose threshold. This threshold may already be reached at a 1.25-/2.5-μg dose in this model. No further enhancement to bone formation/maturation may be observed adding rhBMP-2 above the 2.5-μg dose. The 1.25-20.0 μg dose range did not invoke appreciable aberrant healing events.
Multi-FPGA Accelerator Architecture for Stencil Computation Exploiting Spacial and Temporal Scalability

After the introduction of the OpenCL-based FPGA accelerator design method, FPGAs are getting very popular among high-performance computing. The key to achieving high performance using FPGAs is to design pipelined accelerators. We can increase the pipeline depth beyond the border of one FPGA by connecting multiple FPGAs using high-speed QSFP (quad small form-factor pluggable) connectors. Such a deeply-pipelined accelerator using multiple FPGAs works similar to a single very large FPGA. In this paper, we propose a multi-FPGA accelerator architecture for stencil computation by scaling in spacial and temporal dimensions. According to the experimental results, we achieved performance up to 950 GFLOP/s using one FPGA and nearly doubled the performance using two FPGAs. We achieved a high power-efficiency with competitive performances compared to high-end GPUs.
A Comparative Study Between FinFET and CMOS-Based SRAMs under Resistive Defects

Due to several factors, such as Process Variations (PV), increased leakage current, Random Dopant Fluctuation (RDF), and mainly the Short-Channel Effect (SCE), the miniaturization of planar CMOS transistors reached its limit at the 22nm node. To continue the miniaturization process via technology down-scaling, while preserving system reliability and performance, FinFET devices arise as an alternative to substitute the CMOS transistors. Additionally, Static Random-Access Memories (SRAMs) have been increasingly occupying a great part of Systems-on-Chips (SoCs) silicon area. Designed to reach densities at the limit of the manufacturing process, make this component susceptible to manufacturing defects, including resistive defects. Such defects can escape traditional manufacturing tests, because they may cause dynamic faults during circuits’ lifetime. In this context, a comparison between a 20nm FinFET-based SRAM block and a commercial 65nm CMOS-based SRAM block focusing on resistive defects is carried out. The behavior of defective cells operating over different temperature sets has been investigated by means of SPICE simulations. Results show an expressively higher occurrence of dynamic faults induced by resistive defects in FinFET-based memories when compared to CMOS technology.
Religious Fundamentalism and Terror Management

The study reported herein tested the following hypothesis: Religious fundamentalism can serve a protective function against existential anxiety, such that the need to engage in secular worldview defense when mortality is made salient is reduced for high fundamentalists. The results showed that high fundamentalists engaged in less worldview defense after thinking about their own death versus a control topic. Low fundamentalists, however, engaged in more worldview defense after thinking about their deaths versus a control topic. Exploratory analyses revealed that high fundamentalists' writings about death had a more positive emotional tone and that reactions to the death salience manipulation moderated the impact of fundamentalism on worldview defense. Fundamentalists who saw their deaths in terms of peace and acceptance appeared most protected against terror management concerns.
“It Goes Hand in Hand with the Parties”

Hooking up, or sexual activity outside relationships, is a dominant feature of social life on many college campuses. However, research has yet to explore how social location intersects with campus-level factors to shape students’ negotiations of this script. Interview data from 87 undergraduates at an urban commuter university demonstrate the distinction between “adopting” and “enacting” sexual scripts. Although the majority of students locate hooking up as a salient cultural scenario for their lives, the adoption of hooking up does not neatly translate into its enactment for all students. Where students live emerges as a fault line systematically structuring opportunities for hooking up. There are racial and class divisions even among students with similar residential locations, reflecting the importance of socioeconomic resources and peer group homophily to sexuality. This study points to how race, class, and residence integrally shape the interpersonal sexual scripts of college students.
Transversus Abdominis Plane Block Does Not Provide Additional Benefit to Multimodal Analgesia in Gynecological Cancer Surgery

BACKGROUND: The transversus abdominis plane (TAP) block is a recently described technique involving injecting local anesthetic between the internal oblique and transversus abdominis layers of the abdominal wall. It has been shown to be effective in reducing morphine consumption and improving postoperative pain relief in several clinical settings. METHODS: We performed a randomized placebo-controlled trial comparing bilateral ultrasound-guided TAP blocks (2 × 20 mL 0.5% ropivacaine or 0.9% saline) in adult female patients undergoing midline laparotomy for known or presumed gynecological malignancy. Both groups received multimodal IV analgesia. The primary outcomes for the study were defined as the incidence of “inadequate” analgesia (defined as a score >50 mm on a visual analog scale) with forced expiration at 2 hours postoperatively and total postoperative morphine consumption at 2 hours and 24 hours. RESULTS: Data from 65 patients were included in the study. The groups were comparable in terms of age, weight, surgical duration, and intraoperative morphine doses. There were no significant differences between the control and treatment groups in the proportion of patients with inadequate analgesia either at rest (39% vs. 22%, P = 0.13) or with coughing (61% vs. 53%, P = 0.54) at 2 hours. There was no significant difference in postoperative morphine consumption between the placebo and treatment groups at 2 hours (13.5 mg vs. 11.87 mg, P = 0.53) or 24 hours (34.0 mg vs. 36.1 mg, P = 0.76). There were no significant differences in the incidence of opioid side effects or patient satisfaction. CONCLUSION: This study demonstrated that TAP blockade conferred no benefit in addition to multimodal analgesia in women undergoing major gynecological cancer surgery.
Adipose Tissue Dendritic Cells Are Independent Contributors to Obesity-Induced Inflammation and Insulin Resistance

Dynamic changes of adipose tissue leukocytes, including adipose tissue macrophage (ATM) and adipose tissue dendritic cells (ATDCs), contribute to obesity-induced inflammation and metabolic disease. However, clear discrimination between ATDC and ATM in adipose tissue has limited progress in the field of immunometabolism. In this study, we use CD64 to distinguish ATM and ATDC, and investigated the temporal and functional changes in these myeloid populations during obesity. Flow cytometry and immunostaining demonstrated that the definition of ATM as F4/80+CD11b+ cells overlaps with other leukocytes and that CD45+CD64+ is specific for ATM. The expression of core dendritic cell genes was enriched in CD11c+CD64− cells (ATDC), whereas core macrophage genes were enriched in CD45+CD64+ cells (ATM). CD11c+CD64− ATDCs expressed MHC class II and costimulatory receptors, and had similar capacity to stimulate CD4+ T cell proliferation as ATMs. ATDCs were predominantly CD11b+ conventional dendritic cells and made up the bulk of CD11c+ cells in adipose tissue with moderate high-fat diet exposure. Mixed chimeric experiments with Ccr2−/− mice demonstrated that high-fat diet–induced ATM accumulation from monocytes was dependent on CCR2, whereas ATDC accumulation was less CCR2 dependent. ATDC accumulation during obesity was attenuated in Ccr7−/− mice and was associated with decreased adipose tissue inflammation and insulin resistance. CD45+CD64+ ATM and CD45+CD64−CD11c+ ATDCs were identified in human obese adipose tissue and ATDCs were increased in s.c. adipose tissue compared with omental adipose tissue. These results support a revised strategy for unambiguous delineation of ATM and ATDC, and suggest that ATDCs are independent contributors to adipose tissue inflammation during obesity.
A Pedagogy of Conceptual Progression and the Case for Academic Knowledge.

The potential for academic knowledge to ‘interrupt’ inter-generational reproduction in education is located in the structural contradictions that shape knowledge and democracy. Since the late 1990s research in the sociology of education, which theorises curriculum knowledge using the ideas of Durkheim, Vygotsky and Bernstein, suggests that academic knowledge, far from being the domain of conservative forces, contains the means by which the working-class and marginalised groups may overcome class determinism. The paper argues for a pedagogy of conceptual progression to assist students across the ‘interruption’ or ‘discursive gap’ into academic knowledge. Such a pedagogy need not be confined to its central purpose—that of teaching abstract ideas drawn from their disciplinary systems of meaning and classified for teaching as academic subjects. It can also be the means to mediate the relationship between the context-dependent knowledge of students’ experience and the context-independent knowledge of the academic subject. This pedagogy might be the way to maintain the motivational intention of constructivism and ‘relevance’ approaches that emphasise students’ experience. However, it would use experience to illustrate the abstract ideas acquired in academic subjects, not serve as the source of knowledge itself, nor the knowledge focus.
Cooperative jamming for MIMO wiretap channels

This paper addresses secure communications over MIMO wiretap channels with the help of multiple cooperative jammers. The worst-case scenario for Alice, Bob and jammers is considered: Eve has the knowledge of all channel matrices, while neither her channel matrix nor her location is known to the remaining terminals. We propose an artificial noise aided cooperative jamming (AN-CJ) scheme, allowing the total jamming signals to be nulled at Bob. The new scheme is valid for the case where the eavesdropper has more antennas than the transmitter. To evaluate the performance of the AN-CJ scheme, we first derive a closed-form expression for the achievable ergodic secrecy rate with Gaussian input alphabets. Then, we show how Gaussian input alphabets achieve the ergodic secrecy capacity.
