Intangible investments and cost of equity capital: An empirical research on Vietnamese firms

Abstract Together with the development of knowledge-based economy, investment in intangibles has been dramatically increasing. Although intangibles are widely recognized as primary value drivers for more firms, as evidence of many studies related to the value relevance or the market valuation of intangible investments, little is known in the literature about the cost of equity capital for financing intangible investments, especially in Vietnamese literature extent. This paper’s aim is therefore to empirically investigate the association between a firm’s cost of equity capital and intangible investments detailed by research and development investment, business combination investment and organizational capital investment. We investigate the above relationship through the sample of 120 Vietnamese-listed firms from 2013–2017. Regression result confirmed that both higher level of research and development investment and larger amount of accounting goodwill raise the firm’s overall cost of equity capital since their characteristics of these investments are riskier and less liquid and has a higher level of information asymmetry. Our findings could suggest several implications for managers and shareholders in making their investment decisions. Once again, this study adds to the existing business valuation literature by providing additional evidence of the impact of research and development investment as well goodwill on accounting for equity capital valuation.
The use of an entrepreneurial personality measure to develop a sustainable human competitive advantage

The study utilised a Chinese sample of working adults (N=299) from a state-owned manufacturing enterprise in China to examine the relationships between Psychological Capital (hope, self-efficacy, optimism, and resilience) and other similar constructs. The initial workings of an Entrepreneurial Personality Measure (EPM) were explicated and a systemic framework proposed for EPM to be used in organisations for the development of an entrepreneurial and sustainable human competitive advantage.
On a Nonlinear Hyperbolic Volterra Equation

We study questions of existence, boundedness and asymptotic behavior of the solutions of the initial value problem \[(*)\qquad \begin{array}{*{20}c} {u_t (t,x) - \int_0^t {a (t - s)\sigma (u_x (s,x))_x = f(t,x),\quad 0 < t < \infty ,\quad x \in R. } } \\ {u(0,x) = u_0 (x),\quad x \in R. } \\ \end{array} \] Here $a:R^ + = [0,\infty ) \to R,\sigma :R \to R,f:R^ + \times R \to R,u_0 :R \to R$ are given, sufficiently smooth functions, and the subscripts t and x denote partial derivatives. If $a(t) \equiv 1$, then (*) reduces to a nonlinear wave equation, and it is well known that in this case classical solutions of (*) do not in general exist for all time. However, we show that for a large class of kernels of physical importance equation (*) has global classical solutions for small data. This class of kernels includes all those which are nonconstant, nonnegative, nonincreasing, convex and sufficiently smooth. We also analyze the asymptotic behavior of the solutions.
Polymer-stabilized supercooled blue phase

We report a method to prepare a polymer-stabilized liquid-crystal blue phase that is effective over a wide range of temperature. There are two main key points about this method: (1) A precursor solution is injected into the cell at an enough high temperature above the blue phase–isotropic phase transition point, and (2) a photo-polymerization process with a deeply supercooled blue phase of the precursor solution stabilizes the phase. Thus, a polymer-stabilized “supercooled” blue phase is achieved through photo-polymerization over a wide range of temperature. The proposed method will be very beneficial for manufacturing blue-phase-mode liquid crystal displays.
Domain-Independent Attribution. Part I: Reconstructing the Wind from Estimates of Vorticity and Divergence Using Free Space Green's Functions

Abstract Free space Green's functions may be used to reconstruct the wind over a limited domain from vorticity, divergence, and the wind at the boundary of the domain. When standard finite-difference estimates of the vorticity/divergence field are used, the technique fails to accurately reconstruct the wind in regions where the vorticity or divergence change markedly between grid boxes. The standard finite-difference estimate of vorticity/divergence is accurate provided that the wind varies linearly with distance along the edges of grid boxes. An estimate of vorticity/divergence is derived that accounts for the fact that these requirements are not met when the vorticity/divergence field is locally heterogeneous. This improved estimate is named the G4 estimate. It is not derived from Taylor series. When the G4 estimate of vorticity/divergence is used to reconstruct the wind field, the magnitude of the reconstruction error is an order of magnitude smaller than the reconstruction error associated with the st.
PGD for Solving the Biharmonic Equation

Biharmonic problem has been raised in many research fields, such as elasticity problem in plate geometries or the Stokes flow problem formulated by using the stream function. The fourth order partial differential equation can be solved by applying many techniques. When using finite elements C1 continuity must be assured. For this purpose Hermite interpolations constitute an appealing choice, but it imply the consideration of many degrees of freedom at each node with the consequent impact on the resulting discrete linear problem. Spectral approaches allow exponential convergence whilst a single degree of freedom is needed. However, the enforcement of boundary conditions remains a tricky task. In this paper we propose a separated representation of the stream function which transform the 2D solution in a sequence of 1D problems, each one be solved by using a spectral approximation.Copyright © 2012 by ASME
Measurement and control of thin film uniformity in hollow glass waveguides

Hollow glass waveguides provide an attractive means for the delivery of IR laser power and for broadband temperature and chemical fiber sensor applications. These waveguides are made using liquid- phase chemistry techniques to deposit a thin dielectric film of Agl over metallic Ag on the inside of small-bore silica tubing. By controlling the thickness of the Agl film, we can tailor the optical response of the guides to give low loss at selected IR laser wavelengths or to produce a broadband response. In either case, the losses depend on the thickness uniformity of the Agl film. Initially, the Agl film thickness varies as much as 14% from end to end of a 6-m long guide. A faster Agl deposition rate reduces this variation to only 1.3% over a 5-m long waveguide. This leads to a reduction in the total loss for the hollow guides in the 2 to 12 ? m region.
Preparation and Characterization of Extruded Yam Starch–Soy Protein Isolate Complexes and Their Effects on the Quality of Dough

Extrusion is a method of processing that changes the physicochemical and rheological properties of starch and protein under specific temperature and pressure conditions. In this study, twin-screw extrusion technology was employed to prepare yam starch–soy protein isolate complexes. The structure and properties of the complexes and their effects on the quality of dough were studied. The results showed changes in the X-ray diffraction, rheology, and in vitro digestibility of the complexes. The extruded starch–protein complex formed an A+V-type crystal structure with the addition of soy protein isolate. A small amount of soy protein isolate could improve the complex’s viscoelasticity. As the content of soy protein isolate increased, the content of slow-digesting starch and resistant starch in the complexes increased, and the digestibility decreased. The microstructure of the dough indicated that the network structure of the puffed yam starch–protein complex dough was more uniform than that of the same amount of puffed yam starch. The moisture distribution of the dough showed that with the addition of extruded flour, the closely bound water content of the dough increased, and the weakly bound water content decreased. The hardness, gumminess, chewiness, and resilience of the dough decreased. In conclusion, extruded starch–protein complexes can improve dough quality and provide technical support for the broad application of yam.

This study aims to measure effectiveness of the TOEFL ITP short course program regarding to the achievement of scores. The research used descriptive quantitative in which questionnaire was used to acquire primary data. The results show that the TOEFL ITP short course program is quite effective since it can help the participants to get TOEFL score above 500. CLT Unika Soegijapranta can continue to innovate for this program remains relevant amidst an increasingly massive era.
Estimation of surface heat fluxes and evapotranspiration using community land model

Land surface heat and water fluxes are key components of water and energy cycles between land and atmosphere. Information about these surface fluxes can guide agricultural production and environmental preservation, and manage different ecosystems to mitigate climate change. The main objective of this work is to estimate the surface heat fluxes and evapotranspiration. For this purpose, the Community Land Model Version 3 was used, atmospheric forcing data and flux observation were extracted from AmeriFlux standardized Level 2 database, then surface heat fluxes under two different underlying surfaces were modeled. The results showed that the model works well regarding the simulation of daily surface fluxes and diurnal surface fluxes although these values were underestimated relative to the values observed from eddycovariance. After validation, evapotranspiration was chosen as the indicator for specific comparison. CLM3.0 showed a better performance in simulating the moisture and evapotranspiration.

Representative examples highlighting the capabilities of DL_MESO are given for each of the two methodologies available. Future directions for the package are discussed towards the end of the article.
Identification and Characterization of Salt-Responsive MicroRNAs in Vicia faba by High-Throughput Sequencing

Salt stress has detrimental effects on plant growth and development. MicroRNAs (miRNAs) are a class of noncoding RNAs that are involved in post-transcriptional gene expression regulation. In this study, small RNA sequencing was employed to identify the salt stress-responsive miRNAs of the salt-sensitive Hassawi-3 and the salt-tolerant ILB4347 genotypes of faba bean, growing under salt stress. A total of 527 miRNAs in Hassawi-3 plants, and 693 miRNAs in ILB4347 plants, were found to be differentially expressed. Additionally, 284 upregulated and 243 downregulated miRNAs in Hassawi-3, and 298 upregulated and 395 downregulated miRNAs in ILB4347 plants growing in control and stress conditions were recorded. Target prediction and annotation revealed that these miRNAs regulate specific salt-responsive genes, which primarily included genes encoding transcription factors and laccases, superoxide dismutase, plantacyanin, and F-box proteins. The salt-responsive miRNAs and their targets were functionally enriched by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, which showed that the miRNAs were involved in salt stress-related biological pathways, including the ABC transporter pathway, MAPK signaling pathway, plant hormone signal transduction, and the phosphatidylinositol signaling system, among others, suggesting that the miRNAs play an important role in the salt stress tolerance of the ILB4347 genotype. These results offer a novel understanding of the regulatory role of miRNAs in the salt response of the salt-tolerant ILB4347 and the salt-sensitive Hassawi-3 faba bean genotypes.
Structural Basis for the IgE-Binding Cross-Reacting Epitopic Peptides of Cup s 3, a PR-5 Thaumatin-like Protein Allergen from Common Cypress (Cupressus sempervirens) Pollen

The present work was aimed at identifying the IgE-binding epitopic regions on the surface of the Cup s 3 allergen from the common cypress Cupressus sempervirens, that are possibly involved in the IgE-binding cross-reactivity reported between Cupressaceae species. Three main IgE-binding epitopic regions were mapped on the molecular surface of Cup s 3, the PR-5 thaumatin-like allergen of common cypress Cupressus sempervirens. They correspond to exposed areas containing either electropositive (R, K) or electronegative (D, E) residues. A coalescence occurs between epitopes #1 and #2, that creates an extended IgE-binding regions on the surface of the allergen. Epitope #3 contains a putative N-glycosylation site which is actually glycosylated and could therefore comprise a glycotope. However, most of the allergenic potency of Cup s 3 depends on non-glycosylated epitopic peptides. The corresponding regions of thaumatin-like allergens from other closely related Cupressaceae (Cryptomeria, Juniperus, Thuja) exhibit a very similar conformation that should account for the IgE-binding cross-reactivity observed among the Cupressaceae allergens.
Efficient implementation of rigorous coupled-wave analysis for surface-relief gratings

A computationally efficient implementation of rigorous coupled-wave analysis is presented. The eigenvalue problem for a one-dimensional grating in a conical mounting is reduced to two eigenvalue problems in the corresponding nonconical mounting. This reduction yields two n × n matrices to solve for eigenvalues and eigenvectors, where n is the number of orders retained in the computation. For a two-dimensional grating, the size of the matrix in the eigenvalue problem is reduced to 2n × 2n. These simplifications reduce the computation time for the eigenvalue problem by 8–32 times compared with the original computation time. In addition, we show that with rigorous coupled-wave analysis one analytically satisfies reciprocity by retaining the appropriate choice of spatial harmonics in the analysis. Numerical examples are given for metallic lamellar gratings, pulse-width-modulated gratings, deep continuous surface-relief gratings, and two-dimensional gratings.
Cross-institutional assessment of stress responses in zoo animals using longitudinal monitoring of faecal corticoids and behaviour

Cross-institutional studies that combine non-invasive physiological measures of stress responses and the assessment of individual differences in behaviour and temperament have great potential as tools for assessing the well-being of zoo animals and for identifying key environmental stimuli relevant to well-being. In addition, such studies allow comparison of animals under a wide variety of conditions and enable researchers to obtain sufficiently large samples sizes for statistical data analyses. Faecal corticoid measurements, a method recently developed to monitor adrenal activity in wildlife and domestic species, can be obtained non-invasively as part of the normal husbandry routine. While basic techniques still need improvement, and interpretation of the acquired measures can be challenging, assessment of faecal corticoid concentrations can provide a useful indicator of stress responses under a variety of captive conditions. Here we report on three studies that illustrate this approach and the results that can be obtained. An on-going study reveals significant differences in the pattern of variability of faecal corticoid concentrations between polar bears that are reported by keepers to perform stereotypic behaviour and those that do not. In another study, faecal corticoid measures indicated that stress responses to certain extraneous noises might interfere with the breeding of Hawaiian honeycreepers in captivity. In a study of clouded leopards, higher faecal corticoid concentrations were measured when cats were kept on public display or near potential predators compared to individuals maintained off exhibit or in the absence of visible predators. The findings of an on-going experimental study suggest a causal relationship between the provision of additional hiding spaces and a decline in faecal corticoid concentrations in clouded leopards.
Electromagnetic induction of planar windings with cylindrical symmetry between two half-spaces

A closed-form solution is derived for the equivalent impedance of a planar winding with cylindrical symmetry placed between two half-spaces. This is basically the structure of a domestic induction heating appliance comprised of a planar winding, a metallic vessel, and a lossless magnetic substrate. The first matter addressed is the impedance of a sandwiched single-turn coil, obtained by using the vector potential Helmholtz equation solution, and the result is generalized to n-turn coils. The real part of this impedance represents power dissipated in the form of heat. The proposed model includes geometry dependence, frequency of excitation currents, and electromagnetic properties of both top and bottom media. Enhancement of power dissipation in the conducting media as a result of the inclusion of a magnetic substrate is also explored. Experimental results are presented in order to validate the theoretical model.
Trajectory Tracking Control of a Manipulator Based on an Adaptive Neuro-Fuzzy Inference System

Taking an intelligent trimming device hydraulic manipulator as the research object, aiming at the uncertainty, nonlinearity and complexity of its system, a trajectory tracking control scheme is studied in this paper. In light of the virtual work principle, a coupling dynamic model of the hydraulic system and manipulator system is established. In order to improve the anti-interference and adaptive abilities of the manipulator system, a compound control strategy combining the adaptive neuro-fuzzy inference system (ANFIS) and proportional integral derivative (PID) controller is proposed. The neural adaptive learning algorithm is utilized to train the given input and output data to adjust the membership functions of the fuzzy inference system, then the PID parameters can be adjusted adaptively to accomplish trajectory tracking. Based on MATLAB/Simulink, the simulation model is established. In addition, to prove the effectiveness of the ANFIS-based PID controller (ANFIS-PID), its performance is compared with PID and fuzzy PID (FPID) controllers. The simulation results indicate that the ANFIS-PID controller is superior to the other controllers in control effect and control precision, and provides a more accurate and effective method for the control of agriculture.
The Effects of Trash, Residential Biofuel, and Open Biomass Burning Emissions on Local and Transported PM2.5 and Its Attributed Mortality in Africa

Long‐term exposure to ambient fine particulate matter (PM2.5) is the second leading risk factor of premature death in Sub‐Saharan Africa. We use GEOS‐Chem to quantify the effects of (a) trash burning, (b) residential solid‐fuel burning, and (c) open biomass burning (BB) (i.e., landscape fires) on ambient PM2.5 and PM2.5‐attributable mortality in Africa. Using a series of sensitivity simulations, we excluded each of the three combustion sources in each of five African regions. We estimate that in 2017 emissions from these three combustion sources within Africa increased global ambient PM2.5 by 2%, leading to 203,000 (95% confidence interval: 133,000–259,000) premature mortalities yr−1 globally and 167,000 premature mortalities yr−1 in Africa. BB contributes more ambient PM2.5‐related premature mortalities per year (63%) than residential solid‐fuel burning (29%) and trash burning (8%). Open BB in Central Africa leads to the largest number of PM2.5‐attributed mortalities inside the region, while trash burning in North Africa and residential solid‐fuel burning in West Africa contribute the most regional mortalities for each source. Overall, Africa has a unique ambient air pollution profile because natural sources, such as windblown dust and BB, contribute strongly to ambient PM2.5 levels and PM2.5‐related mortality. Air pollution policies may need to focus on taking preventative measures to avoid exposure to ambient PM2.5 from these less‐controllable sources.
Conducting school-based research during Covid: evaluating the Silver Stories programme

ABSTRACT This paper presents findings from a small-scale pilot evaluation of the Silver Stories programme. Silver Stories involves school-age children reading to older people in the community and is a way of addressing literacy and emotional difficulties, as well as enhancing wellbeing. The authors collected and analysed questionnaire and interview data after a school term of programme implementation, across five schools in England and Wales, during the period of the third lockdown. The main finding was that participants experienced the programme as an opportunity for relationship-building between generations, highlighting the relational nature of reading as a ‘literacy event’ and wellbeing as a product of social interaction rather than an individual attribute. The pilot also indicated that school priorities might have shifted due to COVID-19 from academic attainment to a focus on social and emotional support. Although this was likely a temporary phase, it is also an opportunity to build back better.
Finite element analysis of high-pressure anvils according to the principle of lateral support

In order to extend the lifetime of an anvil made of tungsten carbide used in a large volume cubic high-pressure apparatus (CHPA), we analyzed the properties of an anvil with different magnitudes of interference, matching the steel supporting ring under high pressure using finite element method. It is found that the peak value and distribution of the von Mises stress does not change obviously when the magnitude of interference is smaller than 0.3mm. When the magnitude of interference reaches 0.3mm, the peak value of the von Mises stress and its distribution changes substantially, due to which the performance of the anvil can be significantly affected. Thus, the magnitude of interference ought to be between 0.1 and 0.25mm. The simulated results have been approved in many high-pressure experiments in CHPA.
