description: This article studies the potential of three perennial energy crops, miscanthus, arundo and poplar, to play such a role in the region of Karditsa, Greece. The relevant policy mix is analysed, discussed and outlined as a nexus of interrelated incentives provided by policy makers and the market. Supply curves for diﬀerent energy crops can be used as a decision-making tool by all interested parties within a biomass-oriented supply chain; biomass producers can use them to decide on the economic feasibility and eﬃciency of a suggested energy crop, while industrial players may use them to determine contract prices that ensure long-term availability of inputs. For the purpose of energy crops supply curves estimation a sequential linear programming model is developed, which takes into consideration the deployment of farms’ decisions in time, illustrating crop mix and economic indicators in the medium term. As biomass price increases, arundo cultivation reveals significant possibility of expansion compared to miscanthus and poplar. On the other hand, durum wheat and set-aside are decreased significantly. Aggregate biomass supply curve moves upwards over the studied years.

description: Physical disabled access is something that most cultural institutions such as museums consider very seriously. Indeed, there are normally legal requirements to do so. However, online disabled access is still a relatively novel and developing field. Many cultural organizations have not yet considered the issues in depth and web developers are not necessarily experts either. The interface for websites is normally tested with major browsers, but not with specialist software like text to audio converters for the blind or against the relevant accessibility and validation standards. We consider the current state of the art in this area, especially with respect to aspects of particular importance to the access of cultural heritage.

description: Objective: Ramp drivers have to merge into the through traffic in a limited time and space at interchange merging areas. Different merging decisions are made due to drivers’ various perception abilities of potential danger, which might significantly increase the crash risk. Driving assistance technology (DA) is expected to be an effective way of mitigating the crash risk. Hence, this paper aims to contribute to the literature by designing a model strategy to predict the crash risk of merging drivers in order to enhance the merging assistance system for crash avoidance. Methods: Unmanned aerial vehicle (UAV) was used to collect individual vehicle data to conduct traffic analysis at the microscopic level. A model strategy was proposed to predict the crash risk of merging vehicles which could make sure that ramp drivers are aware of potential risks in advance. Three models (i.e., binary logistic regression, multinomial logistic regression, and nested logit models) were developed and compared. Results: Target-lane-related and merging-vehicle-related variables were found significant with crash risk, including the speed of the merging vehicle, the speed of lead/lag vehicle in the target lane, the type of lead/lag vehicle in the target lane. Different variables were found to be significant in the proposed models. Conclusions: The results suggest that the nested logit model has the highest prediction accuracy. It is concluded that the merging speed, driving ability (i.e., lane-keeping instability), and the vehicle type in the target lane affect the crash risk. Finally, the implementation of the proposed prediction model for merging assistance system is designed. The findings from this study can have implications for the design of the merging assistance system for helping drivers make safe merging decisions and thus enhancing the safety of the interchange merging area.

description: We present the highest resolution --- 15 pc (0.03'') --- ALMA $^{12}$CO(2-1) line emission and 1.3mm continuum maps, tracers of the molecular gas and dust, respectively, in the nearby merging galaxy system NGC 6240, that hosts two supermassive black holes growing simultaneously. These observations provide an excellent spatial match to existing Hubble optical and near-infrared observations of this system. A significant molecular gas mass, $\sim$9$\times$10$^9$M$_\odot$, is located in between the two nuclei, forming a clumpy stream kinematically dominated by turbulence, rather than a smooth rotating disk as previously assumed from lower resolution data. Evidence for rotation is seen in the gas surrounding the southern nucleus, but not in the northern one. Dynamical shells can be seen, likely associated with nuclear supernovae remnants. We further detect the presence of significant high velocity outflows, some of them reaching velocities $>$500 km/s, affecting a significant fraction, $\sim$11\% of the molecular gas in the nuclear region. Inside the spheres of influence of the northern and southern supermassive black holes we find molecular masses of 7.4$\times$10$^8$M$_\odot$ and 3.3$\times$10$^9$M$_\odot$, respectively. We are thus directly imaging the reservoir of gas that can accrete onto each supermassive black hole. These new ALMA maps highlight the critical need for high resolution observations of molecular gas in order to understand the feeding of supermassive black holes and its connection to galaxy evolution in the context of a major galaxy merger.

title: The visualisation of acoustic waves by schlieren and photoelastic techniques
Creators: name: Hall, K.G.
Publisher: name: The Open University
Year: 1975

description: Visualisation of acoustic waves in transparent media is described using schlieren and photoelastic principles. Continuous and pulsed waves are examined. Enhanced sensitivity results for both visualisation systems when a thyratron-triggered spark light source is introduced. The schlieren apparatus demonstrates the Fresnel and Fraunhofer fields of acoustic waves in water. Reflection, refraction, diffraction and transmission through thin plates is demonstrated. The schlieren system is applied to the design of a water column-coupled ultrasonic probe array, for rail testing. Photoelastic experiments include methods of construction of the "plane" and "circular" polariscopes. Three methods by which acoustic waves may be identified are described. The suitability of glass for test pieces is emphasised and compared with modern photoelastic materials. Ultrasonic probes are shown invariably to transmit more than one wave type. Explanation of the sources of these waves is given. Studies of the interactions of compressional and shear waves with horizontal cracks and inclined cracks situated at a model rail bolt hole, are illustrated. Experiments to measure the depth of surface-breaking cracks in rail heads, using Rayleigh waves, show the existence of three received "A scope" signals on the ultrasonic display. These are explained when the interactions of waves with cracks are visualised. An improved testing method is suggested. The circular polariscope is employed to identify the types of stress associated with compressional and shear waves in glass test pieces. The magnitude of static stresses in a cantilever beam is first obtained by Tardy compensation. Further development produces equations enabling stress magnitudes to be calculated using measured optical retardations. A linear relationship is experimentally derived between the probe excitation voltage and the induced stress magnitude for both compressional and shear waves. Stress measurements are verified by comparison with amplitude measurements of received signals expressed logarithmically.

description: The various phase spaces involved in the dynamics of parametrized nonrelativistic Hamiltonian systems are displayed by using Crnkovic and Witten's covariant canonical formalism. It is also pointed out that in Dirac's canonical formalism there exists a freedom in the choice of the symplectic structure on the extended phase space and in the choice of the equations that define the constraint surface with the only restriction that these two choices combine in such a way that any pair (of these two choices) generates the same gauge transformation. The consequence of this freedom on the algebra of observables is also discussed.

description: For those steeped in the ruling paradigm of international trade relations based on gradual liberalization and strengthening rules of trade, the trade policy of the administration of President Donald Trump often appears chaotic, contradictory and economically uninformed – and viewed from the paradigm’s perspective it largely is. The ruling paradigm, however, is not the only paradigm regarding international trade relations. The Trump administration is following an alternative narrative whereby trade is viewed as a zero sum game where a country can only win by garnering concessions from trade partners by hard bargaining or guile. When nefarious trade practices are found, or poor negotiation outcomes identified, swift and strong action is required to rectify the disadvantageous outcome. This alternative paradigm has a long history but has, until now, never informed a U.S. administration’s trade policy since the rules-based multilateral trade institutions were established at the end of the Second World War. The rules-based system imposes constraints on the ability to move swiftly and decisively when the need for action is identified. Removing these constraints is a central facet of the Trump administration’s trade strategy. This article explores the alternative paradigm and the steps being taken to remove the constraints on freedom of action in trade policy.

description: Static image action recognition, which aims to recognize action based on a single image, usually relies on expensive human labeling effort such as adequate labeled action images and large-scale labeled image dataset. In contrast, abundant unlabeled videos can be economically obtained. Therefore, several works have explored using unlabeled videos to facilitate image action recognition, which can be categorized into the following two groups: (a) enhance visual representations of action images with a designed proxy task on unlabeled videos, which falls into the scope of self-supervised learning; (b) generate auxiliary representations for action images with the generator learned from unlabeled videos. In this paper, we integrate the above two strategies in a unified framework, which consists of Visual Representation Enhancement (VRE) module and Motion Representation Augmentation (MRA) module. Specifically, the VRE module includes a proxy task which imposes pseudo motion label constraint and temporal coherence constraint on unlabeled videos, while the MRA module could predict the motion information of a static action image by exploiting unlabeled videos. We demonstrate the superiority of our framework based on four benchmark human action datasets with limited labeled data.
Competition in Air Transport and Equality of Opportunity

description: Air transport, unlike any other mode of transport, has been plagued with teleological anomalies. On the one hand, The Convention on International Civil Aviation (Chicago Convention) – the multilateral treaty applicable to air transport – says in its Preamble that air transport should be operated inter alia with “equality of opportunity” for all, without defining what the word “opportunity” means. Taken literally, this phrase grants every air carrier the opportunity to compete with each other without let or hindrance. On the other hand, the convention states that states have sovereignty over the air space above their territories and that no scheduled international air service may be operated over or into the territory of a state except with the agreement or special authorization of that state. This has rendered air carriers destitute of the liberty to operate internationally scheduled air services and the opportunity to compete fairly and equally with each other. In response, air carriers have devised various commercial measures to bypass this anomaly, such as code sharing, airline alliances and other forms of market access including the use of computer reservation systems. Another anomaly in air transport is that airlines are required to have the nationality of the state in which they are registered, with a requirement that an airline should be owned and effectively controlled by a majority of nationals in that state. This article draws on the genesis of the Chicago Convention through the conference which led to the treaty and analyses the original views of the delegates on competition, liberalization and the evolution of the phrase “equality of opportunity” in air transport.

description: The study looked at the effect of wave action on the rehabilitation success of the brown mussels Perna perna in Coffee Bay. There is a Mussel Rehabilitation Project which attaches mussels onto the rocks and rehabilitation of mussels is considered as good in some sites and bad in some site. One possible reason for that difference between sites could be the effect of wave action. Wave action was measured in six sites along the coast of Coffee Bay between Umtata River mouth and Hole In The Wall. Wave action was measured using cement blocks (water movement), dynamometers (wave force) and local perception of wave action. There was a positive correlation between wave action and rehabilitation success of brown mussels in Coffee Bay. The wave force was higher in good sites than in bad sites. Nqutheni is the best site for rehabilitation and it has highest wave force. There was also more water movement in good sites for rehabilitation. Local people in Coffee Bay use sites that are closer to them, hence they were unable to rank all the sites. People from the north of Coffee Bay were unable to rank sites from the south of Coffee Bay and vice versa. Therefore local perception of wave action could not be used to determine the effect of wave action on mussel rehabilitation in this study. It has been found that it is possible to find high water movement in good sites and high water movement in bad sites and vice versa. The wave force was higher in good sites than in bad sites. Nqutheni is the best sites for rehabilitation and it has highest wave force. There was relation and correlation between wave action and rehabilitation success of brown mussels in Coffee Bay. In conclusion, it can be said that wave action has an effect on mussel rehabilitation of the brown mussels P. perna in Coffee Bay.

description: This article reports on the results of the modelling assessment of the effects of a potential free trade agreement between New Zealand and the EU on the red meat sectors. The primary tool for the analysis was a partial equilibrium trade model, as it enables detailed analysis of the agricultural sector with a high disaggregation of meat commodities. The results suggest that the effect of the FTA would be minor for red meat industries in New Zealand and the EU. Beef and sheepmeat producer returns are expected to remain almost unaltered, and the bilateral trade of those commodities is estimated to stay almost unchanged.

description: Objective: The main aim of this survey study was to evaluate the relative persuasiveness of three newly developed and piloted public education messages aimed at monitoring/reading social interactive technology on a smartphone among young male and female drivers. In accordance with the Step Approach to Message Design and Testing, the messages were evaluated on a number of outcome measures and also explored the influence of self-reported involvement in the target behavior. Methods: Participants (N = 152; 105 F) were aged 17 to 25 years (Mage = 20.14 years, SD = 2.35) and were randomly allocated to either an intervention (one of the three messages) or control (no message) condition. The messages in the intervention group were assessed on acceptance (i.e., behavioral intention and message effectiveness), rejection, and the third person effect (TPE) differential score (i.e., the message is perceived to be more effective for others than for themselves). Results: Hierarchical regression analyses found that, compared to males, females reported: a) lower intention to monitor/read social interactive technology on a smartphone while driving, b) lower rejection; and, c) lower TPE likelihood, irrespective of message. Conclusions: These findings suggest that young male drivers and young female drivers require different message content to be effective and support the importance of including multiple outcome measures to explain the messages’ persuasive effects.

description: Properties of low-variability periods in the time series are analysed. The theoretical approach is used to show the relationship between the multi-scaling of low-variability periods and multi-affinity of the time series. It is shown that this technically simple method is capable of reveling more details about time-series than the traditional multi-affine analysis. We have applied this scaling analysis to financial time series: a number of daily currency and stock index time series. The results show a good scaling behaviour for different model parameters. The analysis of high-frequency USD-EUR exchange rate data confirmed the theoretical expectations.

This class of random matrices appears in the study of the dynamical stability of certain quantum systems and can also be considered as a unitary version of the Anderson model. We further determine the support of the density of states measure and provide a condition ensuring it possesses an analytic density.

description: The influence of solidification on the spreading of liquids is addressed in the situation of an advancing liquid wedge on a cold substrate at $T_p < T_f$, of infinite thermal conductivity, where $T_f$ is the melting temperature. We propose a model derived from lubrication theory of contact-line dynamics, where an equilibrium between capillary pressure and viscous stress is at play, adapted here for the geometry of a quadruple line where the vapour, liquid, solidified liquid and basal substrate meet. The Stefan thermal problem is solved in an intermediate region between molecular and mesoscopic scales, allowing to predict the shape of the solidified liquid surface. The apparent contact angle versus advancing velocity $U$ exhibits a minimal value, which is set as the transition from continuous advancing to pinning. We postulate that this transition corresponds to the experimentally observed critical velocity, dependent on undercooling temperature $T_f-T_p$, below which the liquid is pinned and advances with stick-slip dynamics. The analytical solution of the model shows a qualitatively fair agreement with experimental data. We discuss on the way to get better quantitative agreement, which in particular can be obtained when the mesoscopic cut-off length is made temperature-dependent.

description: A Theorem of Kirichenko states that the torsion 3-form of the characteristic connection of a nearly Kähler manifold is parallel. On the other side, any almost hermitian manifold of type $\mathrm{G}_1$ admits a unique connection with totally skew symmetric torsion. In dimension six, we generalize Kirichenko's Theorem and we describe almost hermitian $\mathrm{G}_1$-manifolds with parallel torsion form. In particular, among them there are only two types of $\mathcal{W}_3$-manifolds with a non-abelian holonomy group, namely twistor spaces of 4-dimensional self-dual Einstein manifolds and the invariant hermitian structure on the Lie group $\mathrm{SL}(2, \C)$. Moreover, we classify all naturally reductive hermitian $\mathcal{W}_3$-manifolds with small isotropy group of the characteristic torsion.

description: The present study reports an electrochemical biosensor for the rapid and selective detection of L-arginine in leukemic blood samples. The biosensor was fabricated using a nanocomposite (PANI/MWCNTs/Fe3O4) film modified glassy carbon electrode (GCE). The partially purified arginine deiminsae (ADI) enzyme from P. putida was immobilized on the modified GCE by cross linking with gluteraldehyde. The characterization and validation of the developed biosensor was performed by various electrochemical techniques including cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry (CA). The limit of detection for biosensor was determined to be as low as 20 μM based on a signal-to-noise ratio equal to three while employing a detection period of 10 s. A linear response for L-arginine was observed across the concentration range from 100 to 1000 µM with an R2 value of 0.9987. The biosensor designed in the present study offers highly specific and sensitive analysis in normal and leukemic blood samples compared to previous reports in the literature. Therefore this device has excellent potential for nano-device fabrication for biomedical applications.

We introduce the so called $γ$-restricted VKOGA, comment on analytical properties and present numerical evaluation on data from a clinically relevant application, the modelling of the human spine. The experiments show that the new stabilized algorithms result in improved accuracy and stability over the non-stabilized algorithms.

description: We consider the {\em Deligne-Simpson problem (DSP) (resp. the weak DSP): Give necessary and sufficient conditions upon the choice of the $p+1$ conjugacy classes $c_j\subset gl(n,{\bf C})$ or $C_j\subset GL(n,{\bf C})$ so that there exist irreducible $(p+1)$-tuples (resp. $(p+1)$-tuples with trivial centralizers) of matrices $A_j\in c_j$ with zero sum or of matrices $M_j\in C_j$ whose product is $I$.} The matrices $A_j$ (resp. $M_j$) are interpreted as matrices-residua of Fuchsian linear systems (resp. as monodromy matrices of regular linear systems) of differential equations with complex time. In the paper we give sufficient conditions for solvability of the DSP in the case when one of the matrices is with distinct eigenvalues.

title: THE USES OF MUSIC AND THEIR EXTENSIONS IN THE NOVELS OF E.M. FORSTER
Creators: name: Colebourne, Alan Stanford
Publisher: name: The Open University
Year: 1976

description: E. M. FORSTER was a novelist with a passionate interest in music. Throughout his life playing the piano, visiting the opera, and attending concerts of orchestral and chamber music constituted his principal forms of pleasure and relaxation; wherever he travelled - in Europe, in Egypt, or in India - the music of the country he visited attracted his keenest attention. But, more than this, music was for him "the deepest of the arts and deep beneath the arts", and it provided a vital stimulus and source of inspiration in the writing of his novels. Although other English novelists before him had shared his interest and had used music in various ways in their novels, Forster develops these uses -in delineation of character, the creation of atmosphere, the underlining of structure, for example - far beyond the limits of his predecessors, and extends them into the realms of the fundamental imagery, the overall structure, indeed the whole resonance of a novel in a way unparalleled even among his contemporaries. While all Forster’s novels have in common a certain number of musical techniques, they reveal not so much a steady chronological development of such techniques as a close relat­ing of specific musical material to the particular task in hand. But when, ultimately, such material becomes inadequate for the task, Forster expands it to encompass the whole sphere of sound and silence. This study surveys the extent of Forster's musical knowledge and ability, indicating the principal influences on him in that area, examines in detail the special musical techniques employed in each novel, illustrates the enormous widening of scope between the first and last, and estimates the importance of his contribution to the development in the uses to which English novelists have put music in their work.
Comparing Multidimensional Sustainability Food Labels with One-dimensional Labels on Consumers’ Willingness to Pay

description: The present study investigated consumers' willingness to pay for sustainable food products when using multidimensional environmental labels versus one-dimensional and no labels. Given that one-dimensional labels are often used to depict food sustainability, the current study aimed to address barriers of one-dimensionality eco food labels’ incomprehensiveness, as well as a lack of a conventional and understandable multidimensional eco-label. We obtained data using an online Qualtrics survey which included 155 undergraduate participants (M age= 21.4, 58.4% Female) recruited through convenience sampling. Participants were randomly assigned to one of three conditions: multidimensional, one-dimensional, and no label (control). We used repeated-measures ANOVAs, posthoc Tukey’s test, Holm’s test, and independent samples t-tests to compare the willingness to pay for four different food items with labels depending on the conditions. We hypothesized that compared to one-dimensional and no label conditions, consumers with pay more for highly sustainable food products when labelled with a multidimensional eco-label and less for multidimensionally labelled food products that were less sustainable. We found that labels did significantly impact consumers’ willingness to pay. However, contrary to our hypothesis, we found that only one-dimensional eco-labels were significantly associated with consumers’ willingness to pay.

title: Toward an Understanding of Chief Digital Officers’ Power in Organizations

description: Organizations are increasingly installing Chief Digital Officers (CDOs) to cope with the challenges of digital transformation (DT). Due to DT’s cross-functional nature and the far-reaching tasks involved, CDOs must wield sufficient influence to manage DT effectively. Thus far, we lack a profound understanding of how CDOs’ power is composed. To address this research gap, we conducted a multiple-case study drawing on 25 interviews across six case companies. We identify several drivers of CDOs’ power, both in terms of formal and informal power types. Particularly, we demonstrate that CDOs’ power depends not only on organizational contingencies but also on the managers’ personal characteristics. We contribute to literature by adding a power notion to discussions on DT in general and CDOs specifically. Further, we sensitize practitioners to establish the CDO role in a way that is endowed with sufficient power and shed light on how CDOs can increase their power base.

description: We perform two-dimensional hydrodynamical simulations of slowly rotating accretion flows in the region of $ 0.01-7\, \mathrm{pc} $ around a supermassive black holes with $ M_\mathrm{BH} = 10^{8} M_{\odot} $. The accretion flow is irradiated by the photons from the central active galactic nucleus (AGN). In addition to the direct radiation from the AGN, we have also included the "re-radiation", i.e., the locally produced radiation by Thomson scattering, line and bremsstrahlung radiation. Compare to our previous work, we have improved the calculation of radiation force due to the Thomson scattering of X-ray photons from the central AGN. We find that this improvement can significantly increase the mass flux and velocity of outflow. We have compared the properties of outflow --- including mass outflow rate, velocity, and kinetic luminosity of outflow --- in our simulation with the observed properties of outflow in AGNs and found that they are in good consistency. This implies that the combination of line and re-radiation forces is the possible origin of observed outflow in luminous AGNs.

description: A map of potential prevalence of Chagas disease (ChD) with high spatial disaggregation is presented. It aims to detect areas outside the Gran Chaco ecoregion (hyperendemic for the ChD), characterized by high affinity with ChD and high health vulnerability. To quantify potential prevalence, we developed several indicators: an Affinity Index which quantifies the degree of linkage between endemic areas of ChD and the rest of the country. We also studied favorable habitability conditions for Triatoma infestans, looking for areas where the predominant materials of floors, roofs and internal ceilings favor the presence of the disease vector. We studied determinants of a more general nature that can be encompassed under the concept of Health Vulnerability Index. These determinants are associated with access to health providers and the socio-economic level of different segments of the population. Finally we constructed a Chagas Potential Prevalence Index (ChPPI) which combines the affinity index, the health vulnerability index, and the population density. We show and discuss the maps obtained. These maps are intended to assist public health specialists, decision makers of public health policies and public officials in the development of cost-effective strategies to improve access to diagnosis and treatment of ChD.
