Funding arts and culture: Everyday experiences and organisational portfolio precarity

This article examines the everyday experiences of arts and cultural organisations in negotiating the UK government and cultural policy priority for funding income diversification. Identifying the challenges of declining public funding and the connected pressures for arts and cultural organisations to be accountable, this article positions income diversification in relation to New Public Managerialism. In doing so, the need to examine the everyday experiences of how arts and cultural organisations engage with and respond to the income diversification priority is established. This article then presents findings from empirical research with arts and cultural organisations under the following three themes: balancing simultaneous sources, managing timelines and working through change. The discussion develops this analysis by identifying portfolio working and precarity as prominent and significant features of organisations’ experiences. Portfolio working is evident in how organisations identify and manage multiple, potential funding sources. Precarity is evident in the uncertainty and instability of managing the multiple funding sources, and in the way that organisations address operational issues of planning and working practices. To conclude, the concept of organisational portfolio precarity is proposed as a way to critically understand the everyday situations and implications of how art and cultural organisations respond to the income diversification priority.
Influence of subtropical Rossby wave trains on planetary wave activity over Antarctica in September 2002

At the beginning of September 2002, strong convection processes over south-eastern Indonesia and over south-eastern Africa have been observed. Due to the strong upper tropospheric divergent outflow, two Rossby wave trains (RWTs) were generated. Their south-eastward propagation was controlled by the mean background flow. These two wave trains are visible in observations. It is hypothesised that these wave trains cause enhanced planetary wave activity fluxes which are a result of an amplified planetary wave 2 in the upper troposphere/lower stratosphere over Antarctica. Such a change of the planetary wave structure was diagnosed in September 2002, prior to the first observed major sudden stratospheric warming event on the Southern Hemisphere. A simplified version of GCM ECHAM4 is used to evaluate the hypothesis. Sensitivity experiments were performed for a mean background flow similar to September 2002. Furthermore, the wave maker approach was used to generate Rossby waves in the subtropical upper troposphere at two distinct locations which are corresponding to the observed regions of divergent outflow. As a main result, after about 2 weeks of model integration with wave maker forcing, we find two RWTs with a south-eastward propagation inducing a polar amplification of planetary wave 2 in the upper troposphere and lower/middle stratosphere. The poleward wave activity flux is enhanced in comparison to the control run without any wave maker forcing. The convergence of the Eliassen–Palm flux causes a 25% deceleration of zonal mean zonal wind in the model stratosphere but no wind reversal. Sensitivity runs support the robustness of these results. The obtained model results highlight the mechanism and confirm the hypothesis that enhanced planetary wave activity in austral polar region in 2002 is caused by enhanced subtropical forcing of two RWTs.
Assessing the lysis of diverse pollen from bulk environmental samples for DNA metabarcoding

Pollen is ubiquitous year-round in bulk environmental samples and can provide useful information on previous and current plant communities. Characterization of pollen has traditionally been completed based on morphology, requiring significant time and expertise. DNA metabarcoding is a promising approach for characterizing pollen from bulk environmental samples, but accuracy hinges on successful lysis of pollen grains to free template DNA. In this study, we assessed the lysis of morphologically and taxonomically diverse pollen from one of the most common bulk environmental sample types for DNA metabarcoding, surface soil. To achieve this, a four species artificial pollen mixture was spiked into surface soils collected from Colorado, North Carolina, and Pennsylvania, and subsequently subjected to DNA extraction using both the PowerSoil and PowerSoil Pro Kits (Qiagen) with a heated incubation (either 65 °C or 90 °C). Amplification and Illumina sequencing of the internal transcribed spacer subunit 2 (ITS2) was completed in duplicate for each sample (total n, 76), and the resulting sequencing reads taxonomically identified using GenBank. The PowerSoil Pro Kit statistically outperformed the PowerSoil Kit for total DNA yield. When using either kit, incubation temperature (65 °C or 90 °C) used had no impact on the recovery of DNA, plant amplicon sequence variants (ASVs), or total plant ITS2 reads. This study highlighted that lysis of pollen in bulk environmental samples is feasible using commercially available kits, and downstream DNA metabarcoding can be used to accurately characterize pollen DNA from such sample types.
Optical and Infrared Lightcurve Modeling of the Gamma-ray Millisecond Pulsar 2FGL J2339.6-0532

We report the detection of a quasi-sinusoidally modulated optical flux with a period of 4.6343 hour in the optical and infrared band of the Fermi source 2FGL J2339.7-0531. Comparing the multi-wavelength observations, we suggest that 2FGL J2339.7- 0531 is a -ray emitting millisecond pulsar (MSP) in a binary system with an optically visible late-type companion accreted by the pulsar, where the MSP is responsible for the -ray emission while the optical and infrared emission originate from the heated side of the companion. Based on the optical properties, the companion star is believed to be heated by the pulsar and reaches peak magnitude when the heated side faces the observer. We conclude that 2FGL J2339.7-0531 is a member of a subclass of -ray emitting pulsars -the `black widows`- recently revealed to be evaporating their companions in the late-stage of recycling as a prominent group of these newly revealed Fermi sources.
Development of Automated Delivery Quality Assurance Analysis Software for Helical Tomotherapy

Background To develop a fully automated in-house gamma analysis software for the “Cheese” phantom-based delivery quality assurance (QA) of helical tomotherapy plans. Methods The developed in-house software was designed to automate several procedures, which need to be manually performed using commercial software packages. The region of interest for the analysis was automatically selected by cropping out film edges and thresholding dose values (>10% of the maximum dose). The film-measured dose was automatically aligned to the computed dose using an image registration algorithm. An optimal film scaling factor was determined to maximize the percentage of pixels passing gamma (gamma passing rate) between the measured and computed doses (3%/3 mm criteria). This gamma analysis was repeated by introducing setup uncertainties in the anterior–posterior direction. For 73 tomotherapy plans, the gamma analysis results using the developed software were compared to those analyzed by medical physicists using a commercial software package. Results The developed software successfully automated the gamma analysis for the tomotherapy delivery quality assurance. The gamma passing rate (GPR) calculated by the developed software was higher than that by the clinically used software by 3.0%, on average. While, for 1 of the 73 plans, the GPR by the manual gamma analysis was higher than 90% (pass/fail criteria), the gamma analysis using the developed software resulted in fail (GPR < 90%). Conclusions The use of automated and standardized gamma analysis software can improve both the clinical efficiency and veracity of the analysis results. Furthermore, the gamma analyses with various film scaling factors and setup uncertainties will provide clinically useful information for further investigations.
Prediction of the Coefficient of Pressure Fluctuations during the Hydraulic Jump Using ELM, GMDH, and M5MT

Pressure fluctuations are a critical phenomenon that can endanger the safety and stability of hydraulic structures, especially stilling basins. Hence, the accurate estimation of the dimensionless coefficient of pressure fluctuations ( C P ′ ) is critical for hydraulic engineers. This study proposed predictive soft computing models to estimate C P ′ on sloping channels. Therefore, three robust soft computing methods, including extreme learning machine (ELM), group method data of handling (GMDH), and M5 model tree (M5MT), were used to estimate C P ′ . The results revealed that ELM was more accurate than GMDH and M5MT methods when comparing statistical indices, including correlation coefficient (CC), root mean square error (RMSE), mean absolute error (MAE), scatter index (SI), index agreement ( I a ), and BIAS values. The performance of ELM was found to be more accurate (CC = 0.9183, RMSE = 0.0067, MAE = 0.0051, SI = 11.88%, Ia = 0.9569) when compared with the results of GMDH (CC = 0.8818, RMSE = 0.0078, MAE = 0.0058, SI = 13.89%, Ia = 0.9361) and M5MT (CC = 0.6883, RMSE = 0.0120, MAE = 0.0090, SI = 21.28%, Ia = 0.7905) in the testing stage. In addition, the BIAS values revealed that ELM slightly overestimated the values of C P ′ , especially at the peak point compared with GMDH and M5MT results. Overall, the suggested soft computing techniques worked well for predicting pressure fluctuation changes in the hydraulic jump.
Sybil Attack Detection in VANET Using Machine Learning Approach

VANET (Vehicular Ad-hoc Network) is a subclass of MANET in which many cars can connect with one another via node to node or equipment erected on the side of the road. However, due to the adaptability of centres and the unexpected trade in geography, there may be opportunities for attacks in VANET. One of the ostensible assaults is the Sybil attack, in which the attacker fabricates unequivocally unique equal personalities to undermine the value of VANET. Sybil creates fictitious identities inside the community as well in order to sabotage attempts to mediate conversations between community nodes. Sybil assaults have an impact on carrier transportation in relation to things like traffic congestion, road safety, and multimedia entertainment. VANETs therefore announce a security mechanism to protect you from Sybil attacks. In this regard, this work puts forth the SDTC method, which completely relies on machine learning techniques to prevent Sybil assaults in VANETs. In order to reduce identification time, increase detection accuracy, and enhance scalability, the SDTC (Sybil node detecting the use of Classification) mechanism uses a few vehicle-specific Extreme Learning Machine (ELM) features. The results suggest that SDTC is a suitable strategy to reduce Sybil assaults and sustain provider service in VANETs.
Hamiltonian operator for loop quantum gravity coupled to a scalar field

We present the construction of a physical Hamiltonian operator in the deparametrized model of loop quantum gravity coupled to a free scalar field. This construction is based on the use of the recently introduced curvature operator, and on the idea of so-called "special loops". We discuss in detail the regularization procedure and the assignment of the loops, along with the properties of the resulting operator. We compute the action of the squared Hamiltonian operator on spin network states, and close with some comments and outlooks.

The information collection instrument – questionnaire – discursive question submitted to the adapted technique of discourse analysis. It was identified that the devaluation of sports culture, which are apparently physical activities, in the school environment from the predominance of Cartesian conception of the body and the absence of access and appropriation of sports culture during Physical Education classes can contribute to sedentary behavior and inactivity. physical activity of children and adolescent students.
High-Power Microwave Limiters Using Recess-Free AlGaN/GaN Schottky Barrier Diodes

In this letter, a thin-barrier AlGaN/GaN Schottky barrier diode (SBD) is proposed and implemented in a three-stage high-power RF limiter module. Benefited from the thin-barrier epitaxy, a recess-free process in the Schottky region is allowed to avoid the plasma damage, resulting in low ON-resistance of 5 $\Omega $ and high withstand voltage characteristics. In addition, the proposed SBDs have achieved a low junction capacitance of 0.35 pF at 0 V bias and a turn-on voltage of 0.5 V. With the optimized SBD and well-designed matching circuits, the limiter has reached a high power capacity of over 10 W in continuous wave (CW), 20 W in pulse mode, and a fast recovery time of 30 ns at a frequency of 3.5 GHz, exhibiting better characteristics than traditional limiters. Both simulation and measured results agree with each other. It indicates that the AlGaN/GaN-based SBD is promising for high-power and high-frequency limiters.

Torque vectoring control of a hybrid drive vehicle to enhance vehicle agility and stability

This paper presents a torque vectoring algorithm that enhances the agility and stability of a hybrid drive vehicle that is a rear-wheel-drive vehicle equipped with two front in-wheel motors and an open differential at the rear axle. Vehicle agility and stability are closely related to the understeer gradient and the yaw rate damping coefficient. Based on this relation, the proposed torque vectoring algorithm is designed to modify the two cornering characteristics using steady-state and transient control inputs, each input with its respective purpose. Firstly, the steady-state control input improves vehicle agility by reducing the vehicle understeer gradient. Secondly, the transient control input improves the lateral stability by increasing the yaw rate damping coefficient. The effects of the proposed algorithm on vehicle dynamic responses are analyzed to select proper design parameter values for the algorithm. The proposed algorithm has been validated via both computer simulations and vehicle tests. From the simulation results, the proposed control algorithm showed better control performance compared to that of the sliding mode based yaw rate controllers, fulfilling the objectives of the steady-state and transient control strategies. The vehicle tests have been conducted with the algorithm implemented in a rear-wheel-drive vehicle equipped with two front in-wheel motors. The vehicle test results show that the proposed algorithm can provide superior performance in enhancing vehicle agility and stability compared to that of the uncontrolled case.
Modeling deuterium fractionation in cold and warm molecular environments with large chemical networks

Observations of deuterated species have long proven essential to probe properties and thermal history of various astrophysical environments. We present an elaborated chemical model that includes tens of thousands of reactions with multi-deuterated species, both gas-phase and surface, in which the most recent information on deuterium chemistry is implemented. A detailed study of the chemical evolution under wide range of temperatures and densities typical of cold molecular cores, warm protostellar envelopes, and hot cores/corinos is performed. We consider two cases of initial abundances, with 1) mainly atomic composition and all deuterium locked in HD, and 2) molecular abundances accumulated at 1 Myr of the evolution of a cold prestellar core. We indicate deuterated species that are particularly sensitive to temperature gradients and initial chemical composition. Many multiply-deuterated species produced at 10 K by exothermic ion-molecule chemistry retain large abundances even when temperature rises above 100 K, and can only be destroyed by dissociation. Our model successfully explains observed D/H ratios of many single, double, and triple-deuterated molecules, including water, methanol, ammonia, and hydrocarbons in a variety of environments (cold cores, hot protostellar envelopes and hot cores/corinos). We list the most abundant deuterated species predicted by our model in different environments of low- and high-mass star-formation regions, as well as key formation and destruction pathways for DCO+, DCN and isotopologues of H2O, H3+ and CH3OH.
Impact of Subsidiary TMT Network Attention on Innovation: The Moderating Role of Subsidiary Autonomy

ABSTRACT This article takes group subsidiaries that were listed in the A-share market of Shanghai and Shenzhen Stock Exchanges in China from 2012 to 2017 as the research subject and innovatively explores the impact of subsidiary TMT (top management team) attention at different networks on subsidiary innovation, considering dual network embedding characteristics and autonomy of subsidiaries. Results show that subsidiary TMT group network attention will inhibit subsidiary innovation, while their external network attention will promote subsidiary innovation, after the inclusion of industry category factors, the effect has changed accordingly, but the moderating effect of subsidiary autonomy on the relationship between subsidiary TMT attention on different networks and subsidiary innovation is always significant. The identification of subsidiary TMT attention not only supplements to current literature's narrow focus on impact of the group parent company attention on subsidiary behaviors, but also broadens theoretical understanding of the driving factors of innovation behavior of subsidiaries. Through expounding on the moderating role of subsidiary autonomy, this article clarifies boundary conditions of subsidiary TMT attention's impact on subsidiary innovation and provides operable guidance for subsidiary TMT to allocate and utilize their attention to promote the development of subsidiary innovation behaviors. 摘要 本文以2012-2017年中国沪深市A股上市且具有集团背景的子公司为对象，结合子公司双重网络嵌入特质，在考虑子公司自主权情况下，创新性的探讨了子公司高管团队不同网络层面注意力对子公司创新的影响。 结果表明，子公司高管团队集团网络注意力会抑制子公司创新行为开展，外部网络注意力对子公司创新具有促进作用，子公司自主权可调节子公司高管团队不同网络层面注意力与子公司创新间关系。 文章对子公司高管团队注意力的识别，不仅是对以往仅关注母公司高管团队注意力对子公司行为作用的补充，还拓宽了对子公司创新行为驱动因素的理论认知。 对子公司自主权调节作用的阐释，明晰了子公司高管团队注意力影响子公司创新的边界条件，并可为子公司高管团队如何分配及利用可促成自身创新行为开展的注意力提供可操作性指导。
The influence of cognitive control on the processing of L2 garden path sentence among Chinese–English bilinguals

Few studies have examined the role of cognitive control in processing ambiguity, let alone the roles of different components of cognitive control. In the current study, the English (L2) Sentence Processing Task and a series of cognitive control tasks were administered among 111 young adult Chinese–English bilinguals to investigate the influence of different components of cognitive control on garden path sentence comprehension, with other factors such as age, socio-economic status, and language proficiency strictly matched. Data analysis results showed a significant garden path effect on response times (RTs) and accuracy among all the participants. The results of independent t-test analyses revealed that the high working memory (WM) group was faster in ambiguity resolution, and so was the high monitoring group. However, there were no differences between the high and low inhibition and shifting groups in ambiguity resolution. These findings reveal that only certain aspects of cognitive control influence garden path sentence comprehension.
Compact Microstrip Patch Filtenna Array Based on Reusable High-Order SIW Cavity

In this letter, a compact microstrip patch (MP) filtenna array designed by reusing high-order substrate integrated waveguide (SIW) cavity is investigated. The SIW cavity operating at TE201 mode not only acts as the first-stage resonator of the filter, but also serves for the four-way dividing realized by the mode power allocation. In addition, by appropriately controlling the coupling coefficient of the output window of the SIW cavity, the radiating 2 × 2 MP array can become the second-stage resonator of the filter. Finally, benefiting from the reuse of the employed high-order SIW cavity, the proposed filtenna array exhibits good performance such as low loss, high efficiency and compact structure. For demonstration, a filtenna array prototype centered at 13.6 GHz is fabricated and tested, showing 13 dBi peak gain and 90% peak efficiency. Good agreement is obtained between simulated and measured results.
