The Relationship of Perceived Value, Perceived Risk, and Level of Trust Towards Green Products of Fast Moving Consumer Goods Purchase Intention
Authors: Zulfikar Rizka , Mayvita Prihatini Ade
Published: August 2018

This study aims to investigate how the relation between the perceived value, perceived risk, level of trust and toward green products purchase intention. This study is a survey research using questionnaires as an instrument. Population and sample used in this study is the community of Banjarmasin and taken as many as 150 respondents using non-purposive sampling method. The study found that Banjarmasin’s public tends to be more considered in its functional value indicators than other indicators such as social value, emotional value, and economic value. They also tend to be more considered at time risk indicators than other indicators such as the risk of physical and psychological risks. Banjarmasin’s public tends to be more considered toward its benefits indicators than other indicators such as trust in the object, and trust in attributes. Perceived value and perceived risk affect the level of public confidence but have no effect to the public purchase intention towards green products. The level of trust significantly influences the purchase intention towards green products. The relationship between the public purchase intention towards green products with the perceived value and perceived risk tends to be indirect and moderated by variable levels of trust.

Published: August 2018

Research conducted is a type of qualitative phenomenological research that reveal and understand the meaning behind the phenomenon of the actions of individuals who perform various actions on the basis of their own perceptions as well as aspects of the background of the action. The number of informants in this study are six people. Sampling method of this study used purposive sampling with snowball sampling method. The findings shows that well recognized or reputable brand considered to be one of the reasons consumers choose to buy stimulation of brand POND’S. Marketing stimuli such as advertising on television, the product that suits consumer needs in affordable price can stimulate consumers buying decision. Low price of POND’S counterfeit product is the main considerations in encouraging buying decision. High consumer loyalty toward original POND’S brand made them decide to buy counterfeit POND’S without considering the authenticity and its side effect on consumer health. Reference groups that dominate consumer minds in buying the counterfeit POND’S product are workmate and store employees where the product is sold. Motivation in seeking new products and the high level of trust toward Unilever brand (POND’S) encourages consumers to buy counterfeit POND’S. Private sources (office colleagues) and commercial (TV advertisement) considered as main information sources for a consumer in buying POND’S and counterfeit POND’S counterfeit.
Role of mechanical morphogenesis in the development and evolution of the neocortex
Authors: Heuer Katja , Toro Roberto
Published: August 2018

During the short period of brain development, nature is able to build the only system we know capable of producing cognition, language, creativity, and consciousness. The neocortex – the outermost layer of the mammalian cerebrum – appears to be the biological substrate of these abilities. Its development requires not only the precise placement and wiring of billions of cells, but also the implementation of mechanisms to ensure a viable cognition despite sometimes dramatic perturbations. Today, this remarkably complex organisation is thought to be genetically encoded, and further refined by activity-dependent processes. We propose that mechanical morphogenesis – the capacity of homogeneously growing elastic tissue to produce complex shapes – can also play an important role. Out of homogeneous growth, mechanical morphogenesis can induce the segregation of the neocortex into mechanical and geometric modules - the neocortical folds. Through the feedback of physical forces on developing tissue, these modules can influence the differentiation and wiring of the neocortex, having a causal role on neocortical development, and providing adaptable and robust units for its evolution.

Do Emotions Result in their Predicted Facial Expressions? A Meta-Analysis of Studies on the Co-ocurrence of Expression and Emotion
Authors: Durán Juan Ignacio , Fernández-Dols José-Miguel
Published: August 2018

That basic emotions produce a facial signal would—if true—provide a foundation for a science of emotion. Here, random-effects meta-analyses tested whether happiness, sadness, anger, disgust, fear, and surprise each co-occurs with its predicted facial signal. The first meta-analysis examined only those studies that measured full expressions through Facial Actions Coding System (FACS). Average co-occurrence effect size was .13. The second meta-analysis included both full and partial expressions, as measured by FACS or another system. Average co-occurrence effect size rose to .23. A third meta-analysis estimated the Pearson correlation between intensity of the reported emotion and intensity of the predicted facial expression. Average correlation was .30. Overall, co-occurrence and correlation were greatest for disgust, least for surprise. What are commonly known as the six classic basic emotions do not reliably co-occur with their predicted facial signal. Heterogeneity between samples was found, suggesting a more complex account of facial expressions
Houses and Society in Roman Celtiberia
Authors: Tirado Jesús Bermejo
Published: August 2018

This article aims to analyse Roman domestic spaces excavated in the region of Celtiberia in central Spain. The main goal is to identify the relationship between social patterns and the spatial configuration of houses. The application of different space syntax methods (accessibility, relative asymmetry, and control value) is the principal means of analysis. This procedure allows us to identify some spatial patterns linked with different patterns of domestic behaviour. In addition, we propose a review of the local epigraphic evidence as a basis for an analysis of the relation between family structures and citizen status in Roman Celtiberia. Inspired by the comparison of the two kinds of evidence, we have also developed an interpretative approach to explain the uneven introduction of Roman models of domestic architecture in some specific sectors of local society.
INTELLECTUAL CAPITAL OF THE ENTERPRISE, ITS ESSENCE AND STRUCTURE
Authors: NAZARENKO Y.A.
Published: August 2018

Topicality. The transition of developed countries to postindustrial society caused increased attention to the research of intellectual capital of enterprises.

Purpose and tasks. The purpose of the article is to systematize approaches to the definition of "intellectual capital" and its structure.

Results. The systematization of different approaches to the definition of intellectual capital, which was carried out by I. Proskvirina, showed a lack of a common point of view on this phenomenon. This is due to the interdisciplinary nature of the study of intellectual capital. R. Gavrilova divided the existing definitions of �intellectual capital� into three groups, respectively, from the point of view of management, accounting, and human capital. Existing views on the structure of intellectual capital are based on the classification of its element, proposed by T. Stewart - human, organizational and client capital. Considered ideas about the structure of intellectual capital are very similar and include human capital, organizational and client capital. some representations also include emotional capital, process capital, intellectual property, market assets, etc. All types of capital that are part of the structure of intellectual capital, with the exception of human capital, have not received wide recognition and have not been studied by a wide range of scientists. This does not allow to establish conformity with the existing generally accepted views on types of capital and does not allow the use of the results of numerous studies on these types of capital (social capital, intangible assets). In this regard, the author's vision is the structure of intellectual capital, consisting of human capital, intangible assets and social capital. This made it possible to propose a new definition of �intellectual capital�.

Conclusions. The proposed definition of �intellectual capital�, its structure and its components allows it to be considered not only in relation to enterprises, but also at the regional and national levels. This opens up new opportunities for assessing intellectual capital, using existing methods for evaluating human capital, intangible assets and social capital.

The effect of carbon nanotubes on the elastic-strength properties of epoxy resin and carbon plastic was investigated. The epoxy resin in the form of Etal Inject-T compound, Sigratex KDK carbon fabric,Taunit-M carbon nanotubes conditionally named as CNT-1, as well as functionalized (modified) variety of them by grafting to the surface of new chemical groups: carboxylated - CNT-2, carboxyl-hydroxylated - CNT-3, amidated - CNT-4 were used in the work. The injection of CNT - 1 into epoxy resin or carbon fiber reinforced plastic did not produce the hardening. At a strain rate of up to 20 mm/min, the epoxy resin with CNT-2-4 consisting of three zones, practically does not affect the elastic zone, but it strengthens the plastic and elastic-plastic zones. It is established that at the strain rate ≥ 20 mm/min the three-zone structure of the epoxy resin passes into a single-zone deformation with parameters σy = 110.5 MPa, εy = 5.05%, E = 2.15 GPa. Under the same conditions of the rate of deformation of carbon fiber reinforced plastic, zones of elastic, elastic-plastic and pseudoelastic deformation are observed. With an increase in the strain rate of 20 mm/min, the single-zone pseudoelastic deformation is characterized by the parameters σs = 425 MPa, εs= 2.3%, Eef = 19.3 GPa. The injection of carbon nanotubes CNT-2-4 into carbon fiber reinforced plastic increased the compressive strength by CNT-2 - 6% of CNT-3 - 12%, CNT-4 - 17%, modulus of elasticity by 13-20%.
Hebrew Literature in the ‘World Republic of Letters’
Authors: Halevi-Wise Yael , Gottesman Madeleine
Published: August 2018

This article charts the international reception of modern Hebrew literature over the last hundred years. It brings large-scale data on the translation of Hebrew literature into conversation with current studies on the dissemination of ‘small’ languages around the world. We pay special attention to publishing trends, genres, literary awards, and other indicators of international recognition. More broadly, we question the scope and definition of a body of literature whose ancient traces have become invisible through translation and whose international readership includes, to some extent, members of its ‘own’ nation who do not share, however, the same language, territory, or cultural experiences. Our goal is to provide a more nuanced understanding of the presence of Hebrew literature beyond its national borders.
Toward a Transversal Reading of Art and Politics in Israel
Authors: Cohen Mor
Published: August 2018

The 2011 Israeli protest for social justice marked a change in the responses of Israeli citizens to political and social matters. The ways in which art and social change intersected during the protest, and the emer- gence of art collectives following the events, call for an understanding of the relation between art and politics in Israel. This article suggests an alternative reading of socially engaged art in Israel. To this end, I use Félix Guattari’s notion of ‘transversality’ and Jacques Rancière’s theory on the ‘aesthetic regime’ to highlight signi cant periods where art and politics have intersected in ways that have challenged Israeli art historiography, often neutralizing the political within an artwork. By using a theoreti- cal framework that emphasizes notions of hybridity and the blurring of boundaries, I make new connections between times, places, and practices that go beyond the binaries of center and periphery, mainstream and alter- native, and aesthetics and politics.

Published: August 2018

Global warming resulted from CO2 level increase in the atmosphere has caused elevation of earth temperature and uncertain climate changes. To prevent the rise of CO2 in the atmosphere can be done by using biomass fuel such as bioethanol. The raw materials of bioethanol can be derived from oil palm empty fruit bunch. Enzymatic hydrolysis utilizes cellulase-producing fungus and in this research, Aspergillus nigerÂ was chosen. The glucose produced is consumed by A niger asÂ carbon source and this is undesirable, therefore it should be minimized as low as possible. Knowing the rate of glucose consumption is important to have a model of the hydrolysisÂ reaction rate which will be helpful in the design process on anÂ industrial scale hydrolysis reactor.Â This study aimed to determine the equations that can beÂ used to approximate the growth rate of A. niger, glucoseÂ consumption, the formation of citric acid, and the kineticÂ parameters used to modeling the kinetics of glucose consumptionÂ by A. niger. Kinetics of glucose consumption by A. niger wasÂ studied in batch system with variation of initial glucoseÂ concentration of 30, 50, 70 g/l. The growth rate of A. niger,Â glucose consumption, and the formation of citric acid wereÂ modeled using 3 equations; i.e. Monod with non-competitiveÂ product inhibition, Luedeking-Piret, and Luedeking-Piret growthÂ associated product formation, respectively. The values of kineticÂ parameters such as Î¼max, Ks, Kp, were 0.65 hour-1, 157.5 g/l, 0.3Â g/l, for initial glucose concentration of 30, 50, 70 g/l, respectively.Â The values of Î± (kinetic parameter for growth associated productÂ formation and Î± would be equal to Yp/x) and Yx/s were 0.4903,Â 0.8531, 0.9863; 0.5124, 0.2704, 0.2381, for initial glucoseÂ concentration of 30, 50, 70 g/l, respectively. Higher initial glucoseÂ concentration would increase Î± but it lowered Yx/s.

Mitochondria-Targeted Antioxidants and Skeletal Muscle Function
Authors: Broome Sophie C. , Woodhead Jonathan S. T. , Merry Troy L.
Published: August 2018

One of the main sources of reactive oxygen species (ROS) in skeletal muscle is the mitochondria. Prolonged or very high ROS exposure causes oxidative damage, which can be deleterious to muscle function, and as such, there is growing interest in targeting antioxidants to the mitochondria in an effort to prevent or treat muscle dysfunction and damage associated with disease and injury. Paradoxically, however, ROS also act as important signalling molecules in controlling cellular homeostasis, and therefore caution must be taken when supplementing with antioxidants. It is possible that mitochondria-targeted antioxidants may limit oxidative stress without suppressing ROS from non-mitochondrial sources that might be important for cell signalling. Therefore, in this review, we summarise literature relating to the effect of mitochondria-targeted antioxidants on skeletal muscle function. Overall, mitochondria-targeted antioxidants appear to exert beneficial effects on mitochondrial capacity and function, insulin sensitivity and age-related declines in muscle function. However, it seems that this is dependent on the type of mitochondrial-trageted antioxidant employed, and its specific mechanism of action, rather than simply targeting to the mitochondria.

In order to realize the resource utilization of coal gasification slag (CGS) and to effectively control the emission of nitrogen oxides (NOx) in coke oven gas, the effect of the reaction conditions and vanadium loading over the CGS catalysts was carried out for the selective catalytic reduction (SCR) of NO by NH3. The various vanadium loaded CGS catalysts were prepared using impregnation methods. The addition of 1% vanadium to the CGS catalyst (V1/CGS) significantly enhanced the NO conversion at a wide temperature range of 180–290 °C. The catalysts were characterized by N2 adsorption/desorption, X-ray photoelectron spectroscopy, H2-temperature programmed reduction, NH3-temperature programmed desorption, Inductively coupled plasma optical emission spectrometer (ICP-OES), thermo gravimetric analyses (TGA), Fourier Transform infrared spectroscopy (FTIR), Scanning electron microscope-Energy dispersive spectrometer (SEM-EDS), and X-ray powder diffraction (XRD). The experimental results show the following: That (1) the NO removal efficiency of the sample CGS3 was the best, and it could be up to 100% under the experimental conditions; (2) The NO removal efficiency of the catalysts was higher in the atmosphere with SO2 than that without SO2; (3) The XRD results indicated the active component of vanadium was homogeneously dispersed over CGS and the active component of catalyst was V2O5 according to the XPS results. In particular, the NH3-TPD spectra of the vanadium loaded CGS catalyst showed that vanadium produced more acid sites, and the Lewis acid sites on the vanadium species were the active sites for the catalytic reduction of NO at 240–290 °C.

Optimal defibrillation timing guided by ventricular fibrillation (VF) waveform analysis would contribute to improved survival of out-of-hospital cardiac arrest (OHCA) patients by minimizing myocardial damage caused by futile defibrillation shocks and minimizing interruptions to cardiopulmonary resuscitation. Recently, fuzzy entropy (FuzzyEn) tailored to jointly measure VF amplitude and regularity has been shown to be an efficient defibrillation success predictor. In this study, 734 shocks from 296 OHCA patients (50 survivors) were analyzed, and the embedding dimension (m) and matching tolerance (r) for FuzzyEn and sample entropy (SampEn) were adjusted to predict defibrillation success and patient survival. Entropies were significantly larger in successful shocks and in survivors, and when compared to the available methods, FuzzyEn presented the best prediction results, marginally outperforming SampEn. The sensitivity and specificity of FuzzyEn were 83.3% and 76.7% when predicting defibrillation success, and 83.7% and 73.5% for patient survival. Sensitivities and specificities were two points above those of the best available methods, and the prediction accuracy was kept even for VF intervals as short as 2s. These results suggest that FuzzyEn and SampEn may be promising tools for optimizing the defibrillation time and predicting patient survival in OHCA patients presenting VF.
Using the Data Agreement Criterion to Rank Experts’ Beliefs

Experts’ beliefs embody a present state of knowledge. It is desirable to take this knowledge into account when making decisions. However, ranking experts based on the merit of their beliefs is a difficult task. In this paper, we show how experts can be ranked based on their knowledge and their level of (un)certainty. By letting experts specify their knowledge in the form of a probability distribution, we can assess how accurately they can predict new data, and how appropriate their level of (un)certainty is. The expert’s specified probability distribution can be seen as a prior in a Bayesian statistical setting. We evaluate these priors by extending an existing prior-data (dis)agreement measure, the Data Agreement Criterion, and compare this approach to using Bayes factors to assess prior specification. We compare experts with each other and the data to evaluate their appropriateness. Using this method, new research questions can be asked and answered, for instance: Which expert predicts the new data best? Is there agreement between my experts and the data? Which experts’ representation is more valid or useful? Can we reach convergence between expert judgement and data? We provided an empirical example ranking (regional) directors of a large financial institution based on their predictions of turnover.
The Duality of Entropy/Extropy, and Completion of the Kullback Information Complex
Authors: Lad Frank , Sanfilippo Giuseppe , Agrò Gianna
Published: August 2018

The refinement axiom for entropy has been provocative in providing foundations of information theory, recognised as thoughtworthy in the writings of both Shannon and Jaynes. A resolution to their concerns has been provided recently by the discovery that the entropy measure of a probability distribution has a dual measure, a complementary companion designated as “extropy”. We report here the main results that identify this fact, specifying the dual equations and exhibiting some of their structure. The duality extends beyond a simple assessment of entropy, to the formulation of relative entropy and the Kullback symmetric distance between two forecasting distributions. This is defined by the sum of a pair of directed divergences. Examining the defining equation, we notice that this symmetric measure can be generated by two other explicable pairs of functions as well, neither of which is a Bregman divergence. The Kullback information complex is constituted by the symmetric measure of entropy/extropy along with one of each of these three function pairs. It is intimately related to the total logarithmic score of two distinct forecasting distributions for a quantity under consideration, this being a complete proper score. The information complex is isomorphic to the expectations that the two forecasting distributions assess for their achieved scores, each for its own score and for the score achieved by the other. Analysis of the scoring problem exposes a Pareto optimal exchange of the forecasters’ scores that both are willing to engage. Both would support its evaluation for assessing the relative quality of the information they provide regarding the observation of an unknown quantity of interest. We present our results without proofs, as these appear in source articles that are referenced. The focus here is on their content, unhindered. The mathematical syntax of probability we employ relies upon the operational subjective constructions of Bruno de Finetti.
Thermodynamic Analysis of Irreversible Desiccant Systems

A new general thermodynamic mapping of desiccant systems’ performance is conducted to estimate the potentiality and determine the proper application field of the technology. This targets certain room conditions and given outdoor temperature and humidity prior to the selection of the specific desiccant material and technical details of the system configuration. This allows the choice of the operative state of the system to be independent from the limitations of the specific design and working fluid. An expression of the entropy balance suitable for describing the operability of a desiccant system at steady state is obtained by applying a control volume approach, defining sensible and latent effectiveness parameters, and assuming ideal gas behaviour of the air-vapour mixture. This formulation, together with mass and energy balances, is used to conduct a general screening of the system performance. The theoretical advantage and limitation of desiccant dehumidification air conditioning, maximum efficiency for given conditions constraints, least irreversible configuration for a given operative target, and characteristics of the system for a target efficiency can be obtained from this thermodynamic mapping. Once the thermo-physical properties and the thermodynamic equilibrium relationship of the liquid desiccant mixture or solid coating material are known, this method can be applied to a specific technical case to select the most appropriate working medium and guide the specific system design to achieve the target performance.

Promotion of retrofit actions on existing buildings is a goal in Italy, since most of them were built before the 80′s when little attention was paid to energy saving. This paper presents an integrated passive design approach to reduce the heating demand and limit the costs of a representative existing residential complex located in Bologna, in the northern part of Italy. To this purpose, we explored different scenarios upon actions taken on the building structure: (1) High efficiency windows; (2) additional insulation on the external walls; or (3) the simultaneous application of high efficiency windows and improved thermal envelope, on both external walls and roofing. The numerical optimization has been performed dynamically using TRNSYS simulation tool, to evaluate energy consumptions in different structural conditions. Then, the developed model has been calibrated by the real consumption data deduced from energy bills (years 2009–2015). Finally, the energy results obtained in the above mentioned different scenarios have been evaluated under an economic assessment of cost investment: It has been highlighted that the payback time (PBT) results to be strongly influenced by the national policies of fiscal incentives. According to the present model, the most profitable condition is obtained when additional insulation on the external walls is applied: The total amount of energy saving resulted to be equal to 930.4 MWh, with an optimal PBT of roughly six years, when tax refund was contemplated.

This paper summarizes the results of the flow boiling heat transfer study with ethanol in a 1.8 mm deep and 2.0 mm wide horizontal, asymmetrically heated, rectangular mini-channel. The test section with the mini-channel was the main part of the experimental stand. One side of the mini-channel was closed with a transparent sight window allowing for the observation of two-phase flow structures with the use of a fast film camera. The other side of the channel was the foil insulated heater. The infrared camera recorded the 2D temperature distribution of the foil. The 2D temperature distributions in the elements of the test section with two-phase flow boiling were determined using (1) the Trefftz method and (2) the hybrid Picard–Trefftz method. These methods solved the triple inverse heat conduction problem in three consecutive elements of the test section, each with different physical properties. The values of the local heat transfer coefficients calculated on the basis of the Robin boundary condition were compared with the coefficients determined with the simplified approach, where the arrangement of elements in the test section was treated as a system of planar layers.
