description: Long standing debate surrounds the position Design and Technology holds in the English and Welsh national curriculum. Some commentators espouse alignment with Science, Technology, Engineering and Mathematics (STEM) as its natural home, whilst others argue that this stifles creativity and takes no account of the ?designerly? nature they consider to be a central tenet of the subject. Against this backdrop, the subject has undergone changes in both prescribed subject knowledge content and examination and assessment arrangements by which pupil progress and attainment are measured. Set against this background, the work presented here summarises a Delphi study which sought to canvass the opinion of established and experienced Design and Technology teachers about how they perceive the attributes, values and unique features of the subject. The results are analysed to give a view of the subject from within the classroom. Analysis reveals that participants in the study consider the "uniqueness" of the subject to prevail over the values and attributes they collectively define it by. The study moves on to discuss the findings in relation to the values and direction which underpin policy documentation that drives and shapes the subject from a national perspective. Finally, the work concludes by highlighting several important areas worthy of further research which have emerged and could be seen as contributory to understanding the nature and essence of Design and Technology.

description: Manufacturers and retailers are major influences in shaping consumers’ food preferences and choices through a variety of activities such as the distribution formats they create, the ways they operate them and the new food and drink products that they introduce. This paper focuses on the UK food and drink market and its purpose is to explore the role of retailers and manufacturers, as agents of change, when introducing food and drink products with sustainability attributes. In particular the following questions were investigated: whether there is trend as regards food and drink products with sustainability related claims in the UK market and what companies are leading the introduction of new products with sustainable claims and in what categories. The data analysed in this paper were extracted from Mintel’s Global New Products Database (GNPD), which provides information about new products launched in selected countries. The data was subject to a statistical analysis to answer the two aforementioned questions. The analysis revealed that products with sustainability claims show a positive trend, with ‘environmentally friendly package’ being the most popular claim. Overall, the results indicate that the sustainability message is increasingly present in the development of new products of retailers and manufacturers in the UK and retailers through their private labels are playing an important role except for the case of products with carbon neutral calims.

description: Er-doped aluminum nitride films, containing different Er concentrations, were obtained at room temperature by reactive radio frequency magnetron sputtering. The prepared samples show a nano-columnar microstructure and the size of the columns is dependent on the magnetron power. The Er-related photoluminescence (PL) was studied in relation with the temperature, the Er content and the microstructure. Steady-state PL, PL excitation spectroscopy and time-resolved PL were performed. Both visible and near infrared PL were obtained at room temperature for the as-deposited samples. It is demonstrated that the PL intensity reaches a maximum for an Er concentration equal to 1 at. % and that the PL efficiency is an increasing function of the magnetron power. Decay time measurements show the important role of defect related non radiative recombination, assumed to be correlated to the presence of grain boundaries. Moreover PL excitation results demonstrate that an indirect excitation of Er 3+ ions occurs for excitation wavelengths lower than 600 nm. It is also suggested that Er ions occupy at least two different sites in the AlN host matrix.
The Equivalence Principle is NOT a Noether Symmetry

description: The connection between the Equivalence Principle and Noether's theorem was discussed in S. Capozziello and C. Ferrara, Int. J. Geom. Meth. Mod. Phys. 21, 2440014 (2024). However, it is known that the Noether symmetry condition is independent of the equations of motions as follows from Hamilton's Principle. In this paper, we critically examine the analysis presented in the aforementioned work, highlighting its flaws, and provide a detailed demonstration that there is no connection between Noether's theorem and the Equivalence Principle. Furthermore, we offer various insights on symmetry analysis to prevent the perpetuation of inaccuracies regarding Noether's work.

description: Production of insect-pollinated crops typically relies on both pesticide use and pollination, leading to a potential conflict between these two inputs. In this paper we combine ecological modelling with economic analysis to investigate the effects of pesticide use on wild and commercial bees, whilst allowing farmers to partly offset the negative effects of pesticides on bee populations by creating more on-farm bee habitat. Farmers have incentives to invest in creating wild bee habitat to increase pollination inputs. However, the optimal allocation of on-farm habitat strongly depends on the negative effects of pesticides, with a threshold-like behaviour at a critical level of the impairment. When this threshold is crossed, the population of wild bees becomes locally extinct and their availability to pollinate breaks down. We also show that availability of commercial bees masks the decrease in pollination services which would otherwise incentivise farmers to conserve the wild pollinator population, therefore indirectly leading to local wild bee extinction. The paper demonstrates the importance of combining ecological modelling with economics to study sustainability in the provision of ecosystem services in agro-ecosystems.

description: We address the perturbation power spectrum generated in the recently proposed ekpyrotic scenario by Khoury et al. The issue has been raised recently by Lyth who used the conventional method based on a conserved variable in the large-scale limit, and derived different results from Khoury et al. The calculation is straightforward in the uniform-curvature gauge where the generated blue spectrum with suppressed amplitude survives as the final spectrum. Whereas, although the metric fluctuations become unimportant and a scale-invariant spectrum is generated in the zero-shear gauge the mode does not survive the bounce, thus with the same final result. Therefore, an exponential potential leads to a power-law expansion/contraction $a \propto |t|^p$, and the power $p$ dictates the final power spectra of both the scalar and tensor structures. If $p \ll 1$ as one realization of the ekpyrotic scenario suggests, the results are $n_S -1 \simeq 2 \simeq n_T$ and the amplitude of the scalar perturbation is suppressed relative to the one of the gravitational wave by a factor $\sqrt{p}/2$. Both results confirm Lyth's. An observation is made on the constraint on the dynamics of the seed generating stage from the requirement of scale-invariant spectrum.

description: Recently, the development and implementation of phishing attacks require little technical skills and costs. This uprising has led to an ever-growing number of phishing attacks on the World Wide Web. Consequently, proactive techniques to fight phishing attacks have become extremely necessary. In this paper, we propose HTMLPhish, a deep learning based data-driven end-to-end automatic phishing web page classification approach. Specifically, HTMLPhish receives the content of the HTML document of a web page and employs Convolutional Neural Networks (CNNs) to learn the semantic dependencies in the textual contents of the HTML. The CNNs learn appropriate feature representations from the HTML document embeddings without extensive manual feature engineering. Furthermore, our proposed approach of the concatenation of the word and character embeddings allows our model to manage new features and ensure easy extrapolation to test data. We conduct comprehensive experiments on a dataset of more than 50,000 HTML documents that provides a distribution of phishing to benign web pages obtainable in the real-world that yields over 93 percent Accuracy and True Positive Rate. Also, HTMLPhish is a completely language-independent and client-side strategy which can, therefore, conduct web page phishing detection regardless of the textual language.

description: Rising fuel and input costs are having a significant impact on the profitability of the fishing sector and increasing the need for vessels to improve operational efficiency. In particular, smaller vessels that do not have the economies of scale must maximize input-output efficiency to remain viable. There is also the consideration that improved fuel efficiency in fishing vessels will reduce the carbon footprint of the sector. Measuring vessel and fleet efficiency is important for these reasons, but it is also important to correctly measure efficiency to determine how best to manage a fleet and determine how ecosystem, regulatory and market changes will impact fleet viability and operability. This paper uses stochastic frontier analysis (SFA) to assess the efficiency of fishing vessels in the Irish demersal otter trawl nephrops fishery. Clear evidence of efficiency-heterogeneity across vessels in the fishery is reported, even when controlling for vessel-specific characteristics, such as vessel length, age and engine power. The drivers of efficiency are also investigated and we find that the use of vehicle monitoring systems (VMS) data allows for more spatially and temporally detailed information to improve fleet efficiency analysis.

description: An infra-red fixed point of ${\mathcal N}=1$ super-Yang-Mills theory is believed to be dual to a solution of five-dimensional gauged ${\mathcal N}=8$ supergravity. We test this conjecture at next to leading order in the large $N$ expansion by computing bulk one-loop corrections to the anomaly coefficient $a-c$. The one-loop corrections are non-zero for all values of the bulk mass, and not just special ones as claimed in previous work.

description: BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an intense Raman spectrum with sharp and well-defined features. Here, we report the evolution of the Raman spectrum of BaZrO3 single crystals in a broad temperature range (4--1200~K) and discuss its origin with the support of detailed first-principle calculations of the lattice dynamics. Phonon calculations are performed not only for the cubic phase of BaZrO3, but also for the low-symmetry phases with octahedra tilts that have been suspected to exist at the nanoscale. We show that the Raman spectrum shows no direct evidence for these nanodomains, but can instead be explained by classical second-order Raman scattering. We provide an assignment of the dominant features to phonon modes combinations. In particular, we show that the high frequency range of the spectrum is dominated by overtones and shows an image of the phonon density of states corresponding to the stretching modes of the oxygen octahedra.
Tidally induced radial-velocity variations in close binaries

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A theoretical framework for the determination of tidally induced radial-velocity variations in a component of a close binary is presented. Both the free and the forced oscillations of the component are treated as linear, isentropic perturbations of a spherically symmetric star. Resonances between dynamic tides and free oscillation modes are taken into account by means of the formalism developed by Smeyers et al. (1998). The amplitude of the tidally induced radial-velocity variations seen by the observer depends on the orbital eccentricity and on the orbital inclination. The amplitude increases with increasing orbital eccentricity and is most sensitive to the value of the orbital inclination when 20 < i < 70. In the case of a 5 solar mass ZAMS star with a 1.4 solar mass compact companion, it is shown that resonant dynamic tides can lead to radial-velocity variations with amplitudes large enough to be detected in observations. The shape of the tidally induced radial-velocity curves varies from very irregular for orbital periods away from any resonances with free oscillation modes to sinusoidal for orbital periods close to a resonance with a free oscillation mode. Our investigation is concluded with an application to the slowly pulsating B star HD 177863 showing the possibility of resonant excitation of a high-order second-degree g-mode in this star.

description: The Waterville fishery provides angling and other recreation amenities to the public at a nominal cost. However, the use-value which this site provides is not completely captured by market transactions. Benefits which must be consumed in situ make the Travel Cost Method (TCM) the most appropriate choice of revealed preference technique for estimating their value. Data for this analysis was sourced from an online survey, but many respondents were first approached on-site, and links to the survey questionnaire were also advertised on a local conservation website, so self-selection bias was expected. A negative binomial model with a correction for endogenous stratification was estimated, and it outperformed both the standard Negative Binomial and Poisson models. The resulting estimate of per trip consumer surplus was €300. Furthermore, there was a lack of any evidence to support the idea that the site’s benefits are inferior goods. In light of this, and of the high use-values associated with the site, the conclusion drawn from the analysis is that future development plans should prioritise the health of the local ecosystem before other quality improving measures.

description: A method of Fourier transform near-infrared (FT-NIR) spectroscopy combined with partial least squares (PLS) model was successfully applied to investigate the hydrolysis kinetics of four kinds of silane coupling agents (phenyltriethoxysilane, vinyltriethoxysilane, 3-mercaptopropyltriethoxysilane, 3-chloropropyltriethoxysilane) in an acid-catalyzed EtOH system. The fast scanning speed and high sensitivity of the FT-NIR spectroscopy, and the powerful data processing ability of the PLS, enabled the method to quantitatively and accurately catch the fast changing H2O concentration during the hydrolysis processes without delay, realizing the study of the fast-paced hydrolysis reactions of the silane coupling agents. The results showed that electrophilic substitution occurred in the hydrolysis reactions, which followed second-order reactions and greatly depend on the catalyst concentration and reaction temperature. The hydrolysis rate constants, activation energy, and Arrhenius Frequency factors were gained. In conclusion, the FT-NIR PLS model is a powerful tool for hydrolysis kinetics researching of the silane coupling agents.

description: Various studies have been made to test the efficiency of market in Lebanon and Arab Gulf States (AGS) theoretically and empirically, focusing mainly on building a model using the conventional finance. The purpose of this paper is to test the efficiency of AGS financial markets as well as the Lebanese one based on stationary method; furthermore it explores the reasons behind the non-efficiency in case it exists. However, to realize this objective ,this paper overviews the different methods behind testing efficiency in order to choose and use the most common one ,furthermore it studies also the Volatility using ARCH and GARCH and the Financial Characteristics behind each market, which leads to either enhance or reduce market efficiency so far. Findings prove that Lebanese, Abu Dhabi, Qatar, and Kuwait markets tend to be efficient in its weak form whereas Dubai, Saudi Arabia and Amman markets are non-efficient based on the average monthly data series and financial characteristics of the market over a specific period of time.

The Effect of Tunisian Cyclical Fiscal Policy on Economic Volatility: Understanding the Role of Institutional Quality
Creators: name: Bahrini Wadiaa
Publisher: name: figshare
Year: 2019
Subjects: Economics

description: The recent decades have been marked by major instabilities that have increased the sensitivity of Tunisian business cycles to internal and external shocks. The economists must take this structural problem into account in their current decisions. Therefore, most institutional reforms were made in response to those instabilities after the Tunisian revolution. In addition, several fiscal indicators are partly intended to stabilize Tunisian economic fluctuations and avoid excessive government deficits. The influence of fiscal policy can be examined by distinguishing between cyclical and discretionary policies. Accordingly, it is interesting to investigate the impact of institutional quality on Tunisian fiscal policy conduct. This paper measures the effect of cyclical fiscal policy on Tunisian volatility. It analyzes the role of four fiscal indicators such as total government expenditure, administrative expenditure, capital expenditure, and loan expenditure. In addition, this paper tests the role of institutional variables on the stabilizing effect of fiscal policy. Indeed, the results are significant, and a tendency to apply a cyclical fiscal policy proved to be possible to reduce Tunisian volatility. Tunisian's experience is likely to be of interest to other developing countries.

description: There is very little empirical evidence supporting the claims that family farming is a ‘superior’ form of organisation for agricultural production. This paper investigates the comparative output effects of family labour in several EU Member States. No positive output effects can be discerned when farms are characterised by a low level of technical efficiency. In the case of efficient farms, the incremental effects of family labour are characterised by a number of thresholds. The paper only finds limited support for the claimed positive output effects of family farming and these only materialise after a considerable family involvement is committed.

description: We report experimental investigationd of optical pulse group velocity reduction and probe pulse regeneration using a Raman scheme. The new scheme which does not rely on the on-one-photon resonance electromagnetically induced transparency (EIT), has many advantages over the conventional method which critically relys on the transparency window created by an EIT process. We demonstrate significant reduction of group velocity, less probe field loss, reduced probe pulse distortion, and high probe pulse regeneration efficiency.

The early decline is steep (1.68 $\pm$ 0.10 mag 100 d$^{-1}$), followed by a shallower plateau phase (0.47 $\pm$ 0.24 mag 100 d$^{-1}$). The optically thick phase lasts for 118 d, similar to Type IIP. The $^{56}$Ni mass estimated from the radioactive tail of the bolometric light curve is 0.082 $\pm$ 0.019 M$_\odot$. High velocity component contributing to the absorption trough of H$α$ and H$β$ in the photospheric spectra are identified from the spectral modelling from about 57 - 97 d after the outburst, suggesting a possible SN ejecta and circumstellar material interaction. Such high velocity features are common in the spectra of Type IIL supernovae. By modelling the true bolometric light curve of SN 2016B, we estimated a total ejected mass of $\sim$15 M$_\odot$, kinetic energy of $\sim$1.4 foe and an initial radius of $\sim$400 R$_\odot$.

Creators: name: Fitri Indriawati
Publisher: name: figshare
Year: 2019
Subjects: Economics

description: The purpose of this study is to investigate the value relevance of Islamic social reporting disclosures in influencing the firm value. Islamic Social Reporting (ISR) is a Corporate Social Responsibility (CSR) reporting model for sharia-based institutions. Indonesia has not required ISR as a mandatory disclosure to sharia-based companies. This study was designed using causal research and analysed using multiple regression analysis. The sample of this research is companies listed in the Jakarta Islamic Index (JII) from 2014–2017. The result shows while ISR is still voluntary disclosure in Indonesia, and there are no standards for governing implementation, ISR does have incremental value in affecting firm value. The implications are significant for sharia-based companies in implementing ISR.

description: Thanks to recent progress in terms of materials properties, polymer field-effect transistors (FETs) operating in the MHz range can be achieved. However, further development towards challenging frequency ranges, for a field accustomed to slow electronic devices, has to be addressed with suitable device design and measurements methodologies. In this work, we report n-type FETs based on a solution-processed polymer semiconductor where the critical features have been realized by a large-area compatible direct-writing technique, allowing to obtain a maximum frequency of transition of 19 MHz, as measured by means of Scattering Parameters (S-Parameters). This is the first report of solution-processed organic FETs characterized with S-Parameters.

description: Techniques using membranes for the treatment of wastewaters usually promote higher quality of treated water when compared to other processes. Among them, pervaporation has advantages in terms of selectivity in addition to low working pressure, which can prevent clogging problems. Polysulfone and polyurethane have complementary characteristics and are interesting in the context of membranes for industrial applications. In this sense, the aim of this work was to prepare and characterize polysulfone/polyurethane-based membranes and tested them with a simulated wastewater containing the reactive black dye and sodium chloride by pervaporation. In their manufacture, thermal treatment (at 60 °C) and photo-radiation treatment (using ultraviolet light) were also applied. The characterizations were performed using different analytical tools. In general, it was possible to verify that all membranes have a dense layer. The thermal analysis allowed to define that the indicated working temperature is below 50 °C. With respect to the simulated wastewater treatment, all membranes reached 100% selectivity. Concerning the saline solution, the mean selectivity was around 98.5%. Moreover, the permeate flow values ⁣⁣were within the range presented by commercial membranes ranging from 1.6 to 2.4 kg m-2 h-1. Although for the photoirradiated membranes the photo-graft reaction has occurred, among all membranes, the blend without any treatment stood out from the others, presenting the highest permeate flow of the simulated wastewater. Finally, the results reveal that these membranes are capable of recovering wastewater from textile processes, in addition to having the potential to remove salts from water through the pervaporation process.

description: We present analytical exploration of novel activation functions as consequence of integration of several ideas leading to implementation and subsequent use in habitability classification of exoplanets. Neural networks, although a powerful engine in supervised methods, often require expensive tuning efforts for optimized performance. Habitability classes are hard to discriminate, especially when attributes used as hard markers of separation are removed from the data set. The solution is approached from the point of investigating analytical properties of the proposed activation functions. The theory of ordinary differential equations and fixed point are exploited to justify the "lack of tuning efforts" to achieve optimal performance compared to traditional activation functions. Additionally, the relationship between the proposed activation functions and the more popular ones is established through extensive analytical and empirical evidence. Finally, the activation functions have been implemented in plain vanilla feed-forward neural network to classify exoplanets.

description: Lane Emden differential equation of the polytropic gas sphere could be used to construct simple models of stellar structures, star clusters and many configurations in astrophysics. This differential equation suffers from the singularity at the center and has an exact solution only for the polytropic index n=0,1 and 5. In the present paper, we present an analytical solution to the fractional polytropic gas sphere via accelerated series expansion. The solution is performed in the frame of conformable fractional derivatives. The calculated models recover the well-known series of solutions when α=1. Physical parameters such as mass-radius relation, density ratio, pressure ratio and temperature ratio for different fractional models have been calculated and investigated. We found that the present models of the conformable fractional stars have smaller volume and mass than that of both the integer star and fractional models performed in the frame of modified Rienmann Liouville derivatives.

description: A method of Fourier transform near-infrared (FT-NIR) spectroscopy combined with partial least squares (PLS) model was successfully applied to investigate the hydrolysis kinetics of four kinds of silane coupling agents (phenyltriethoxysilane, vinyltriethoxysilane, 3-mercaptopropyltriethoxysilane, 3-chloropropyltriethoxysilane) in an acid-catalyzed EtOH system. The fast scanning speed and high sensitivity of the FT-NIR spectroscopy, and the powerful data processing ability of the PLS, enabled the method to quantitatively and accurately catch the fast changing H2O concentration during the hydrolysis processes without delay, realizing the study of the fast-paced hydrolysis reactions of the silane coupling agents. The results showed that electrophilic substitution occurred in the hydrolysis reactions, which followed second-order reactions and greatly depend on the catalyst concentration and reaction temperature. The hydrolysis rate constants, activation energy, and Arrhenius Frequency factors were gained. In conclusion, the FT-NIR PLS model is a powerful tool for hydrolysis kinetics researching of the silane coupling agents.
Quality of Intellectual Capital Disclosures: The Role of Market Share and Financial Distress in Thai’s Agricultural and Resource Sectors

description: This study aims to examine the factors that influence the quality of intellectual capital disclosure (ICD). This study contributes to research related to ICD by using the value of the market share and financial distress as independent variables, in addition to the level of firm size. This study also tests the ICD in each of its components. Firm size is indicated by the amount of assets owned by the company; while market share is measured by the proportion of company sales in the total sales of one industry. Financial distress is indicated by the Altman-Z score, where the greater the Z-score, the safer the company from the risk of bankruptcy. ICD are more qualified if disclosures are supplemented by numerical and monetary data. The sample used is 50 agricultural and resource sectors companies registered in the Thai Stock Exchange from 2013-2017. This study finds that the quality of HCD is increasing along with the company's high assets. Market share can improve the quality of RCD, but on the other hand, reduce the quality of HCD. The safer the company from the bankruptcy risk, the higher the quality of the HCD. There are a variety of ICD measurements that can be used by subsequent research and are complemented by various other independent variables that can enrich empirical findings in ICD cases.

description: By applying mirror symmetry to D-branes in a Calabi-Yau geometry we shed light on a $G_2$ flop in M-theory relevant for large $N$ dualities in ${\cal N}=1$ supersymmetric gauge theories. Furthermore, we derive superpotential for M-theory on corresponding $G_2$ manifolds for all A-D-E cases. This provides an effective method for geometric engineering of ${\cal N}=1$ gauge theories for which mirror symmetry gives exact information about vacuum geometry. We also find a number of interesting dual descriptions.
description: Identification of parameters as well as the computation of the superpotential is extended to all A-D-E cases. Additional references are also included

description: This paper examines the issue of compensation payments for farmers affected by an animal disease outbreak. Recent literature has questioned the scope for the widely used “single mechanism” of compensation payments to incentivise farmers both to undertake costly on-farm biosecurity and to comply with disease reporting requirements. This paper develops a simple theoretical model of the farmer’s decision environment in this situation and uses a numerical analysis to illustrate both the potential for a range of levels of compensation payments to achieve this dual incentivising, and how this range is affected by changes in the parameter values of the farmer’s decision environment. Particular attention is given to the problem of spatial variation among farmers in the baseline of likelihood of a disease outbreak, and the findings of the paper are used to suggest a policy solution to this problem.

description: General relativistic effects have been shown to increase the energy deposition rate due to the process $ν\barν \to e^{+}e^{-}$ in supernovae and neutron stars. In this paper we study the effect of inclusion of the rotation of the star in the general relativistic treatment. We show that inclusion of rotation results in a reduction in the heating rate as compared to the no rotation case.
