LIQUIDITY AND SOLVABILITY ON PROFITABILITY : A STUDY ON TOLL ROAD SUB -SECTORS COMPANIES LISTED AT INDONESIAN STOCK EXCHANGE
Authors: Nababan Ivan Morgan
Published: July 2021

In the current era of development, Indonesian companies not only have to compete with domestic companies but face diverse competition from abroad. These conditions have also fueled competition in the industry sector. By maintaining and able to develop the companies, and achieving company goals both management and company leaders are often faced with various problems both technical, administrative and financial. Therefore the company management must take rational decisions and can be accounted for and the decision-maker requires a clear picture of the problems faced by the company. If the company increases the amount of debt as a source of funds it can increase financial risk. If the company cannot manage funds raised from debt productively, it can have a negative effect and have an impact on decreasing company profitability. Conversely, if the debt can be managed well and used for productive investment projects, it can have a positive influence and have an impact on increasing the profitability of companies. Investment in infrastructure is considered that it is one of the best ways to develop money. infrastructure has the opportunity to get a large return on investment.Profitability is the company's ability to make a profit concerning sales, total assets, and own capital (Sartono in Ima Hernawati, 2007). High profitability will illustrate the effectiveness of management in managing the company in generating profits. If the effectiveness and efficiency of capital use can be achieved, then there is a possibility that the company will make a large profit. Liquidity is related to the problem of a company's ability to meet its financial obligations that must be met immediately. The amount of payment instruments (liquid instruments) owned by a company at one time is the paying power of the company concerned. A company that has the power to pay may not be able to fulfill all financial obligations that must be fulfilled immediately or in other words the company may not have the ability to pay. The solvency of a company shows the company's ability to meet all financial obligations if the company is currently liquidated. The definition of solvency is intended as the company's ability to pay all its debts, both long-term and long-term. This research is expected to add insight into the effect of liquidity on profitability in other companies on the Indonesia Stock Exchange

Politicians “Stay Home”
Authors: Garcia Santamaria Sara
Published: July 2021

This paper analyses the intimate space of politicians at home during lockdown through their personal Instagram accounts, using both live stories (which I have been saving daily), the pictures and videos they post and the accompanying text. In order to do so, it will focus on two young female politicians who have become iconic for left-wing movements around the world. They are Ada Colau, Mayor of Barcelona (Spain), and Alessandria Ocasio-Cortez, representative for New York’s 14th congressional district (USA). As previous political outsiders who are deeply involved in activism and belong to what some will call a left-wing populist wave, AOC and Colau interact with their followers in “an authentic way”, often posting very intimate and apparently uncurated images of their daily life. The goal of the paper is to examine how they construct authenticity and connect with their constituencies during the COVID-19 lockdown through a qualitative visual rhetorical analysis.

The Views of International University Students About Online Education
Authors: Karakus Ismail , Karakus Sena
Published: July 2021

Currently, international university students are working hard to cope with many problems in socio-cultural, psychological and economic terms. Particularly after Covid-19 epidemic experienced by the whole world in early 2020, they have started to face greater problems. Therefore, in this study, the aim is to examine the opinions of international university students taking Turkish online lessons about course practices and learning-teaching processes. Qualitative research design was used in this study, and the data were collected through focus group interviews. Participants of the study consist of 18 international university students enrolled in a state university in the academic year of 2020-2021 and receiving Turkish language education at B2 level. While some of the international university students expressed positive opinions regarding the economical and comfortable online education process, some of them expressed negative opinions; namely the lack of communication, the difficulties experienced in online exams and the language learning process and the inefficiency of education. Most of the students stated that the online education process has both positive and negative aspects. As the advantages of this educational process, students pointed out facilitating academic processes easily, managing time, being healthy and saving money. On the other hand, it was highlighted that there are technical, personal, educational, health and language difficulties in the online education process. As solution suggestions for these difficulties, the participants made suggestions on eliminating the problems in technical and physical conditions, including more motivational activities and improving the educational process.
SHINE_color: controlling low-level properties of colorful images
Authors: Dal Ben Rodrigo
Published: July 2021

Visual perception combines top-down processes arising from participants individual histories, such as expectations and goals, and bottom-up processes that arise from visual stimuli properties, such as luminance and contrast. The precise control of low-level visual stimuli properties is essential when investigating visual perception. Without it, for instance, investigations of bottom-up processes are virtually impossible and investigations of top-down processes risk major confounds when testing and formulating hypotheses. The SHINE (spectrum, histogram, and intensity normalization and equalization) toolbox for MATLAB (Willenbockel et al. (2010) allows precise control of images' Fourier amplitude spectra, the normalizing and scaling of luminance and contrast, and exact histogram specification optimized for perceptual visual quality. Following Willenbockel and cols (2010) advices, here we present an adaptation of the SHINE toolbox, named SHINE_color, which extends SHINE functionalities by allowing the parametrical manipulation of low-level properties of both static and animated colorful images.

Many psychological treatments have been shown to be cost-effective and efficacious, as long as they are implemented faithfully. Assessing fidelity and providing feedback is expensive and time-consuming. Machine learning has been used to assess treatment fidelity, but the reliability and generalisability is unclear. We collated and critiqued all implementations of machine learning to assess the verbal behaviour of all helping professionals, with particular emphasis on treatment fidelity for therapists. We conducted searches using nine electronic databases for automated approaches of coding verbal behaviour in therapy and similar contexts. We completed screening, extraction, and quality assessment in duplicate. Fifty-two studies met our inclusion criteria (65.3% in psychotherapy). Automated coding methods performed better than chance, and some methods showed near human-level performance; performance tended to be better with larger data sets, a smaller number of codes, conceptually simple codes, and when predicting session-level ratings than utterance-level ones. Few studies adhered to best-practice machine learning guidelines. Machine learning demonstrated promising results, particularly where there are large, annotated datasets and a modest number of concrete features to code. These methods are novel, cost-effective, scalable ways of assessing fidelity and providing therapists with individualised, prompt, and objective feedback.
The finer details? The predictability of life outcomes from Big Five domains, facets, and nuances
Authors: Stewart Ross , Mõttus René , Soto Christopher J. , Seeboth Anne , Johnson Wendy
Published: July 2021

Associations between personality traits and life outcomes are usually studied using the Big Five domains and, occasionally, their facets. But recent research suggests these associations may be driven by the items (reflecting nuances) chosen to measure these traits. Using a large dataset (N = 6,126), we examined associations with 53 self-reported outcomes using domains, facets and items (markers for nuances), training and validating models in different sample partitions. Facets better predicted outcomes than domains (on average, 18.0% vs 16.6% of variance explained), but items provided the most accurate predictions (on average 20.9%). Removing domain and facet variance from items had no effect on their predictive validity, suggesting that outcome-related information was present in items’ unique variances (nuances). Item-based prediction also showed the highest outcome-specificity (discriminant validity). These observations, replicating previous indications, suggest that personality traits’ associations with outcomes are often driven by narrow personality nuances.
Design of An Active Power Ankle-Foot Orthosis with Myoelectric Control for Drop-Foot Rehabilitation
Authors: Setiawan Rudi , Sabar Sabar , Madi Madi
Published: July 2021

Drop-foot is an inability to lift the foot when walking due to muscle weakness or paralysis. One of the common rehabilitation aids for stroke sufferers with drop-foot is Ankle Foot Orthosis (AFO). This tool serves as a stabilizer for road pattern balance. However, most of the AFO used is passive, so it doesn't help users run properly. Therefore, an active AFO system has been designed as a rehabilitation aid. This AFO is designed with motor control from myoelectric feedback signal (EMG) and also a semi-dynamic ankle joint so that it is more flexible to help the user when stepping. The AFO movement set of to the foot's position in Dorsi and Plantarflexion conditions based on the EMG parameter received by the control unit. Then, the angle sensor standardizes the user's ankle position so that the foot fits the states that have set. This design uses the fuzzy logic method, which functions to control the rotation of the servo motor. The interface system is for monitoring parameters. In this design, pressure sensors (force), EMG, and angle sensors transmitted wirelessly to a computer are used for data analysis under the needs of real-time statistical data processing.

Exploring the Prospective of Dark Tourism in Pashupatinath: A Hindu Pilgrimage Site, Nepal
Authors: Kunwar Ramesh Raj , Homagain Bikram , Karki Neeru
Published: July 2021

A unique and increasingly pervasive feature within the tourism landscapes in the post-modern world is the special interests of tourists in death and anything associated with death. It is often believed that those who indulge in death and disaster site tours could potentially awaken their spiritual journey. The visitor immersions, in the spaces of death, and the events that have taken place or are re-created, triggers social conscience, or some shared emotion or an experience of involvement, with the death event. Reckoning to this facet, Pashupatinath temple- a place of pilgrimage for the followers of Santana Vedic religion which shows the comprehensive aspect of Hindu death rituals, symbols and processes has been chosen. The study proposes the site as a dark tourism destination and explores the convergence of cultural heritage site, pilgrimage and death rituals in the area that is associated with its characterization- particularly with reference to the witnessing of live open pyre burning death rituals at the cremation ground (ghat) that exclusively showcases the eastern phenomenon of death-spectatorship exhibited by Hindu death ritual. Despite an immense influence of the site in the tourism industry, the eastern dark tourism potential induced by the site has not been recognized formally by the tourism stakeholders. Even though it is widely consumed by the western visitors as a tourist element. The phenomenon of Hindu death tradition in the ghats of Pashupatinath is inclusive of all the death-related rituals and is a threshold of transition and transgression, a place in between life and death. Henceforth, as the central tenet of dark tourism being “the death”, Hindu death rituals in Pashupatinath could be firmly brought into the realms of dark tourism discourse. The findings are based on the prevalence of push factors that encourages consumption of the proposed site as a dark tourist product in liminal conditions (an in-between position). To be more specific, the practice of intellectualization of emotion, convenience of visits, edutainment elements, practice of moral disengagement. The prospective of dark tourism in Pashupatinath, if entitled to the mere promotion of the crematory site, may send a negative connotation and raise moral and ethical concerns. Hence, tourism stakeholders should consciously introduce the phenomenon as an accompaniment to the popularized mainstream religious and cultural value of the site.
The Myth of Resilience
Authors: Richardson Angelle Elaine
Published: July 2021

This poem discusses resilience as an adaption to circumstances children cannot control. It comes from the viewpoint that resilience assumes that there is something to which one can bounce back. However, children who are placed in the foster care system and/or adopted, especially from birth, are born into spaces to which there is no return, yet they are labeled resilient. Children who experience these traumatic circumstances are not resilient, they are adaptable and learn how to thrive and move forward.

From Riel to the Métis
Authors: Miller J.R.
Published: July 2021

Although miscegenation must have been one of the earliest and most common effects of the expansion of Europe, its consequences have been relatively little studied by historians of Canada. Indeed, one of the few general histories of the western mixed-blood population suggests – only half-jokingly, one suspects – that the Métis people of Canada were founded nine months after the landing of the first European. Perhaps because of traditional historiographical emphases, a limited methodological sophistication, or simply as a consequence of racist inhibitions on the part of Euro-Canadian historians who dominated the field until recently, the history of the Métis has not received much concerted and systematic attention from academic historians.

The article considers the concepts of soft skills and hard skills and their significance for the development of a specialist in the professional field. Key characteristics of "soft" and "hard" competencies are provided. The content analysis of definitions "soft skills" and "hard skills" is carried out, the general and distinctive features in approaches are noted. On the principle of indivisibility of hard and soft skills the specificity of training in business is built. Some companies rely on soft skills when recruiting, realizing that a person who can learn quickly will grasp the necessary skills on the fly. Other companies first focus on technical skills, realizing that a person will be able to develop soft skills in the process of work, performing tasks and implementing projects [2]. Each author considers and defines the concepts of "soft skills" and "hard skills" in their own way. But all definitions are partially interconnected, some of them are intertwined with each other. Soft skills are related to communication skills that are necessary for successful work in professional activities. Hard skills are the ability to perform certain tasks that can be clearly demonstrated. Currently, there are many models of soft skills, but they have not only differences but also similarities. For example, many re-searchers consider communication skills, decision-making, and time management to be mandatory elements of the model. Undoubtedly, the influence of the formed "soft skills" and "hard skills" and the constant development of soft and hard competencies for the successful achievement of goals, competent use of skills, knowledge and abilities in profes-sional activities and to achieve competitiveness in the labor market.
More on the Influence of Injector Geometry and Carrier Gas Flow Rate on Spray Pattern and Particle Temperature
Authors: Fincke J.R. , Swank W.D. , Haggard D.C.
Published: July 2021

Recently it has been suggested that the carrier gas jet interaction with the plasma can have a large effect on the resulting particle temperature. The postulated interaction is through deflection of the main plasma jet and by delaying the heating of particles by the formation of a "cold" gas bubble. We have examined the effect of the gas jet itself on the temperature of the particles by attempting to artificially form a cold gas bubble using a separate, closely oriented gas jet. The effect of the "twin" co-flowing jet was evaluated by measuring its effect on the mean and standard deviation of the particle injection velocity and the resulting spray pattern and particle temperature. Additionally we have used alternative carrier gases with similar density but with specific heats that are higher than argon by a factor of two. A measurable but minor effect on particle temperature is observed.
The Benefits of the PROTAL Process on the Adhesion of Thermal Sprayed Coating
Authors: Barbezat G. , Folio F. , Coddet C. , Montavon G.
Published: July 2021

In this paper, the authors evaluate the effect of different laser parameters on the adhesion of coatings produced by the Protal method. The process incorporates an atmospheric thermal spray torch and a pulsed Nd:YAG laser, achieving surface preparation (comparable to grit blasting) and coating deposition in a single step. Coating adhesion was measured via tensile testing and an indentation method, and the rupture areas (along with some of the coating-substrate interfaces) were examined using SEM techniques. The results show that with the new process chemical and metallurgical bonding can be achieved between the substrate and coating by spraying in air.

The method, called particle flux imaging (PFI), records light emitted by thermal spray particles and the hot propellent carrier-medium in which they are conveyed. Brightness distributions corresponding to temperature and density profiles are represented by sets of ellipses that are compared in real time to a reference image. An image analysis algorithm adjusts relevant spray parameters based on the comparisons, maintaining a constant and unchanged spraying process.

A novel technique and an instrument for on-line, quantitative imaging diagnostics and process control in thermal spraying have been developed and tested in laboratory and industrial conditions. In-flight spray particles are imaged by their natural luminosity with a short-exposure, digital CCD camera system. Particle images are processed using digital image processing techniques in a PC computer. The number of particles per frame and the spatially resolved particle velocities are calculated from the images. Spectrally resolved image information is further used to determine pyrometric two-color particle temperature. A number of different modes of data presentation have been developed. The developed instrument can be used to determine particle number, velocity and temperature distributions of individual in-flight particles from the imaged region of interest of the plume. Dividing the imaged area into smaller sections, spatial distributions of these parameters can be studied. SprayWatch system provides a technically simple, easy to operate, single imaging instrument, which can provide a visual overview of the spray plume in combination with quantitative evaluation of the most important spray particle parameters. In this paper examples of using the monitoring system with plasma and HVOF spraying are presented. Preliminary test results of using a semiconductor laser generated light sheet to detect cold particles is also demonstrated.

A powder velocity diagnostic system in ElectroThermal Chemical Spray (ETCS) coating technology has been developed. The powder velocity is a crucial variable that influences the coating quality. However, non-of the existing methods is suitable for the velocity measurement in the special conditions of the ETCS technology. The proposed diagnostic system is based on a familiar technique called Double Rotating Disk. It measures the powder particle time-of-flight between two parallel disks. The disks are rotated by a high-speed motor. The front disk has holes distributed on its circumference. Particles passing a hole are deposited on the second disk. The displacement between the position of the deposited particles spot center and projection of the hole center on the second disk is inversely proportional to the velocity. The method allows the measurement of particle velocity with accuracy better than 10%. The results are in a good agreement with theoretical model predictions. The method is able, also, to observe the powder deposition rate and the particles spatial distribution inside the powder cloud according to their dimensions as a function of time during the coating process.

Since plasma jets, which have been used as heat sources of thermal plasma spraying process, expand adiabatically under a low pressure environment, the plasma temperatures drastically fell down to 2000K at the nozzle out let at 30Pa chamber pressure. However, the plasma jets still had enough reactivity to form hard nitride layer on the surface of the titanium samples by only a few minutes treatment. In this study, in order to obtain useful information for the practical applications of this plasma as low temperature and high rate surface modification processes, nitriding of nitriding steel and carbon steel using supersonic expanding hydrogen/ nitrogen mixture plasma jets were carried out. Consequently, though surface hardening was occurred slightly in the case of carbon steel, surface hardening was obviously promoted in the case of nitriding steel. In both cases, surface hardening was promoted with increasing hydrogen flow rate and thermal damages of the samples due to heat transfer from plasma jets weren't observed. Besides, according to the results of wear testing, wear mass loss of nitrided samples were much lower than that of non-nitrided samples. From these results, this process was found to have a high potential even in the case of surface modification of steel materials.

Tungsten carbide-cobalt coatings are extensively used to protect surfaces from wear in many types of applications, such as compressor piston rods, pump plungers, shaft sleeves on centrifugal pumps and fans, and midspans of compressor blades in gas turbines. The wear behavior in any application is strongly influenced by the basic physical and mechanical properties of such coatings. Fracture toughness as a mechanical property indicates the resistance to fracture in the presence of a sharp crack, and thus provides a measure of the intrinsic strength of the cemented carbides coatings. In this study, Vickers indentation tests have been used to quantify the in-plane fracture behavior of various WC-based coatings deposited by the High Velocity Oxy-Fuel (HVOF) spray process. The indentation cracks are analyzed in terms of standardized relations that utilize radial-median crack geometries. It is shown that the fracture properties of HVOF WC-Co coatings are anisotropic, and depend strongly on the microstructure and composition of the coatings. The crack propagation is determined by the porosity, binder mean free path, and the shape, size, and distribution of the reinforcing carbide particles. The erosion resistances of the coatings have also been discussed as a function of the fracture properties and mechanisms. It is shown, in this study, that the Vickers indentation method is a useful and convenient technique for determining the in-plane fracture toughness of HVOF sprayed WC-based coatings.

Experimental measurements have been carried out with the aim of investigating the residual stresses generated during plasma spray deposition of glass composite coatings. The research shows that the behaviour of these materials is fundamentally different from metals and ceramics. The quench stress in the glass composites can be eliminated by plasma-scanning. This is attributed to their low glass transition temperatures, which enable the stresses to be completely relaxed. The work also shows that the addition of alumina as a second phase allows the expansion mismatch between the coating and the steel substrate to be controlled. Control of the second-phase volume-fraction enables the residual stress in the composite coatings to be reduced to zero. Real-time measurements on deflection and temperature show that the dimensions of the substrate, plasma operating conditions and scanning rate have substantial effects on the temperature profiles within the deposits. Keywords: glass composite coatings, thermal stress, plasma spraying.
Residual Stress Determination from a Laser-Based Curvature Measurement

Published: July 2021

Thermally sprayed coating characteristics and mechanical properties are in part a result of the residual stress developed during the fabrication process. The total stress state in a coating/substrate is comprised of the quench stress and the coefficient of thermal expansion (CTE) mismatch stress. The quench stress is developed when molten particles impact the substrate and rapidly cool and solidify. The CTE mismatch stress results from a large difference in the thermal expansion coefficients of the coating and substrate material. It comes into effect when the substrate/coating combination cools from the equilibrated deposit temperature to room temperature. This paper describes a laser-based technique for measuring the curvature of a coated substrate and the analysis required to determine residual stress from curvature measurements. Quench stresses were determined by heating the specimen back to the deposit temperature thus removing the CTE mismatch stress. By subtracting the quench stress from the total residual stress at room temperature, the CTE mismatch stress was estimated. Residual stress measurements for thick (>1mm) spinel coatings with a Ni-Al bond coat on 304 stainless steel substrates were made. It was determined that a significant portion of the residual stress results from the quenching stress of the bond coat and that the spinel coating produces a larger CTE mismatch stress than quench stress.

Thermal spray coatings are subjected to mechanical loadings in many applications, and there is a need to evaluate the mechanical properties of these coatings. Mechanical properties of interest in the performance of thermal spray coatings include fatigue life, wear resistance, bond strength. Young's modulus, Poisson's ratio, and residual stresses. One property that has a large effect on the performance of thermal spray coated parts is the residual stress distribution in the thermal spray coating and in the substrate. Thus, it is important to have (1) a fundamentally sound method for evaluating residual stresses and (2) a written recommended procedure for applying the method. ASM International is not a standard writing organization. Yet, the increased use of thermal spray coatings and the need for documentation on methods for evaluating mechanical properties of thermal spray coatings have generated a need to prepare Recommended Practices. To meet this need, the ASM International Thermal Spray Society has formed three subcommittees to prepare Recommended Practices for thermal spray coatings. This paper describes a draft form of a Recommended Practice for evaluating residual stresses in thermal spray coatings. This Recommended Practice is being developed by the Subcommittee on "Evaluating of Mechanical Properties of Thermal Spray Coatings". The method, called the Modified Layer Removal Method, has been presented in several papers and has been used for a variety of different coatings. The paper describes the dimensions of the test specimen, the equipment needed, the procedure for removing layers, and the methods for collecting and interpreting the data to evaluate through thickness residual stresses. The Recommended Practice (RP) is in Draft form, but is presented to let the thermal spray community know about the RP effort and invite comments and volunteers to write other RP's.
