The Effect of Implementing Occupational Health and Safety Programs on Suspected COVID-19 Incidents in PT. Maruki International Employees

World Health Organization (WHO) has shown Corona Virus Disease 2019 as a pandemic. The spread of COVID-19 in Indonesia has now spread across locations and across countries, accompanied by an increase in the number of problems and/or the number of deaths. To overcome the spread of Covid-19, both the government and business actors have made various efforts so that the spread of the Covid-19 virus can be prevented and overcome, especially the spread of the Covid-19 virus in office areas by implementing new normal rules in the workplace through the Occupational Safety and Health program. Based on the results of observations from one of the lead managers of PT Maruki International Indonesia, who said that there had been cases against some of his employees who were suspected of being suspected of having COVID-19, we as authors consider it necessary to raise this issue to be investigated for input for the company so that it can be used to implement the implementation. Occupational Health and Safety program against suspected cases of the Covid-19 virus among PT Maruki International Indonesia employees. The purpose of this study was to determine the effect of the implementation of the Occupational Health and Safety Program on the incidence of suspected Covid-19 virus among employees of PT Maruki International Indonesia. This type of research is quantitative research with a design approach cross sectional study. The sample used is 150 employees from a population of 241 employees. Collecting quantitative data using a checklist and analyzed by univariate, bivariate. Thus, it can be said that the Behavioral Improving Body Immunity variable affects the variable incidence of suspected covid-19. It is hoped that with the results of this study the government and related company management can provide a policy to deal with the spread of the corona virus in the workplace. Keywords: Activities of wearing masks; hand washing habits; efforts to maintain distance and suspected cases of covid-19.
Optical and Photocatalytic Properties of CuxS/ZnO Composite Thin Films Deposited by Robotic Spray Pyrolysis Deposition

This article reports on VIS-active composite thin films based on zinc oxide (ZnO) and copper sulfide (CuxS) deposited using robotic spray pyrolysis deposition (SPD) for the study of the optical and photocatalytic properties. The first step involves the SPD deposition of a CuxS layer onto the glass substrate at 300°C. The second step consists of the deposition of a ZnO layer onto the CuxS layer to form glass/CuxS-ZnO composites that were further annealed at 400°C. The development of the composite thin films was confirmed by XRD and EDX analyses. The band gap energy ( E g ) of the bare ZnO thin films decreased from 3.15 eV to an activation energy value of 2.8 eV after the deposition of the ZnO thin layer onto the CuxS layer and from 2.8 to 2.08 eV after annealing the CuxS-ZnO composite at 400°C. The UV-VIS irradiation (5.5% of UV, G = 55 W / m 2 ) of a 10 ppm methylene blue solution was used to investigate the photocatalytic properties of the CuxS-ZnO composites. The annealed CuxS-ZnO thin films at 400°C demonstrates better photocatalytic activity compared to CuxS-ZnO composites deposited at 300°C. The enhanced photocatalytic efficiency of the annealed CuxS-ZnO thin films may be the result of the diode structure and the increased crystallinity that prevent the electron-hole recombination.
The Impact of COVID-19 Pandemic Information on Sectoral Stock Performance during Lockdown and New-Normal: An Evidence from Indonesia Stock Exchange

The Indonesian economy has weakened in every sector since pandemic Covid-19. The study investigates how the stock return in the impacted and unimpacted industry reacts to death and cases information about Covid-19. Based on previous studies, behavioral changes also occur in society. Changes in consumption of mass products and also the behavior of fast-food products move in opposite directions. In addition, changes also occur in employee performance due to limitations related to activities. In addition, this study also considers the response from the Indonesian government regarding changes in people's behavior and the increase in cases related to Covid-19. The Indonesian government, in this case, implemented several policies as a response to the incident where the Indonesian government finally imposed restrictions on social activities followed by a transition period to maintain the economic cycle in Indonesia. This study shows that in both the impacted and unimpacted industries and the lockdown period and the new-normal period in the Indonesian version, information related to the Covid-19 case significantly negatively affected stock returns, while information on deaths due to Covid-19 has a negative effect that is not significant. This result suggests the practitioner considers which other information affects investment decision during the Pandemic in the future.
Global Biogeochemical Cycle of Lithium

The total human mobilization of Li from the Earth's crust, >1,000 × 109 g/year, is much larger than Li mobilized by the natural processes of chemical and mechanical weathering (94 and 132 × 109 g/year, respectively), representing a ∼500% perturbation of the global cycle of Li by human activities. The anthropogenic perturbation of the global Li cycle shows enhanced releases to freshwaters from oil‐produced water (46 × 109 g/year), leaching of coal ash (7–20 × 109 g/year), and extraction of groundwaters (29 × 109 g/year). The sum of these anthropogenic sources more than doubles the natural transport of dissolved Li to the sea in rivers (69 × 109 g/year). Currently, releases from the excretion of therapeutic drugs and disposal of lithium‐ion batteries are a small component of the transport of Li in rivers, although the latter may increase markedly as lithium‐ion batteries dominant global energy storage. Human emissions of Li particles to the atmosphere—55 × 109 g/year from coal combustion—comprise about 38% of the emission of Li to the atmosphere from various sources. The inputs to the atmosphere are more than the estimated deposition of Li from the atmosphere, which is poorly constrained by available data.
Solvent Effects for Vertical Ionization Processes in Liquid Water and at the Liquid-Vapor Interface

Liquid microjet photoelectron spectroscopy is a state-of-the-art experimental technique that provides avenues for investigating ultrafast charge and energy transfer processes in liquid water and aqueous solutions. The emphasis of this work is placed on making contact with recent liquid microjet experiments of hydrated electrons, e(aq), in liquid water and at the liquid-vapor interface from a computational perspective. Since its discovery nearly 55 years ago, e(aq) has attracted significant attention from both experimental and theoretical communities due to its crucial role in radiation chemistry and its relatively elusive structure in liquid water at ambient conditions. Historically, the primary observable of hydrated electrons has been a well-characterized optical absorption spectrum, but with the advent of liquid microject spectroscopy, this has shifted to measurements of its relative binding energy below vacuum level. Some experiments utilizing this methodology have been interpreted to suggest that e(aq) at the liquid-vapor interface is energetically dissimilar than in liquid water, and that, unlike the more strongly bound species in liquid, it can potentially undergo destructive reactions with solvated DNA molecules. A variety of computational strategies are employed to demonstrate that the spectroscopic properties of hydrated electrons in liquid water are actually quite similar to the interfacial species. To that end, mixed quantum-classical molecular dynamics simulations are performed where e(aq) in liquid water and at the interface is described ii by two different one-electron pseudopotentials. These simulations suggest that the presence of e(aq) at a liquid-vapor interface is fleeting at ambient conditions, and to experimentally distinguish it from the bulk species using standard spectroscopic techniques would be challenging. Non-equilibrium polarizable continuum models (PCMs), in conjunction with MP2 and DFT methods, are then employed to compute vertical ionization energies in liquid water. However, computing these quantities in anisotropic environments, such as at an interface, is not possible with traditional PCMs. Therefore, a novel methodology is presented for computing vertical ionization energies at a liquid-vapor interface that was developed to incorporate non-equilibrium solvent polarization effects for molecules immersed in arbitrary dielectric environments. This method is applied to e(aq), alkali metal cations, and halide anions in liquid water, for which vertical ionization energies have been measured, and also to predict these quantities at the interface where some liquid microjet measurements do not yet exist.
The Optimum Wood Procurement Scenario and Its Dynamic Management for Integrated Energy and Material Production in Carbon-Neutral Forest Industry

The digitalization of the forest sector, the increased demand of energy-wood, as well as faster market changes have increased the number of challenges for wood procurement of the forest industry. The aim of the study is to optimize wood procurement (upstream of supply chain) of energy and material production in integrated situations, and to consider the effects of production changes on the management of procurement regions. Three scenarios described integrated production situations in a carbon-neutral forest industry: (1) declining export, (2) energy reform, and (3) extensive energy reform. Time-varying capital-, cost-, and energy efficiency of the dynamic wood-flow model affected the competitiveness of the procurement regions. As a novel contribution, energy efficiency was modeled using the price of emission allowance as a cost parameter. The results show the positive effects of the energy reforms, which partly compensate for the declining exports. In addition, it is possible to change wood procurement in the regions in a market-oriented way. Decision makers should optimize purchases, inventories, and procurement resources as business processes, which are also considered success factors for the forest industry in integrated production situations. The strategic solution of extensive energy reform provides a potential approach for carbon-neutral customer-oriented supply chains, but it needs tactical energy efficiency analysis in future studies of sustainability, if the ultimate goal is to implement a carbon-free forest industry and bioeconomy.
Revealing Molecular Level Indicators of Collagen Stability: Minimizing Chrome Usage in Leather Processing

Chromium(III) sulfate is extensively used in leather processing to stabilize the collagen molecules in hides and skins. Although its excess usage causes severe environmental pollution and health concerns, the role of chromium in stabilizing collagen still remains poorly understood. For the first time, by integrating a number of techniques, including real-time small-angle X-ray scattering, differential scanning calorimetry and natural cross-link analysis, we reveal crucial molecular-level indicators of collagen stability. The results indicate that collagen molecules achieve maximum molecular stability at concentrations as low as 1.8 wt % even if excess chromium (>3.7%) is introduced into the collagen matrix. At low concentrations (1.8% to 3.7%), the active amino acid residues are saturated via covalent bonding with chromium. Any excess chromium interacts purely non-covalently with the collagen molecule and, we propose, can be substituted by environment-friendly alternatives. Further, important natural cros.
Are Teachers Boundedly Rational? How Beliefs and Context Affect Decision-Making

ABSTRACT There has been a dramatic shift in how teachers are understood in teacher cognition and educational research (from trained technicians to rational decision-makers). Likewise, there has been a change in how the teaching paradigm is understood (from the banking model to the constructivist model). This article uses the bounded rationality concept and draws on teachers’ beliefs and contextual factors to explore minority language education policy in a Global South setting. It shows that preexisting biases and institutional constraints limit teachers’ capacity to self-reflect and make optimal rational decisions that may be in students’ best interests and responsive to their needs.
Grit and Self-Efficacy in Using E-Learning Among Postgraduates in Higher Education Institutions

Abstract The emergence of the fourth industrial revolution sparked a need for changes in higher education institutions in term of teaching and learning. E-learning can attract learners into the learning environment with its myriad of benefits. Despite its abundance of benefits, learners seem to not fully utilize the e-learning portal and later tend to discontinue using it. This article aims to explore the relationship between grit, self-efficacy, and self-perceived performance among postgraduates using an e-learning portal. A total of 441 data inputs were collected from postgraduate learners via an online survey and analyzed using structural equation modeling (SEM). The findings indicate that grit displayed a positive significant impact on self-efficacy and students’ self-perceived performance and that self-efficacy positively affects self-perceived performance. Theoretical and practical contributions are presented and discussed. The limitations of the research are explained, and suggestions for future research are also elaborated.
Effects of the adoption of management control practices on profitability: evidence from Latin America

ABSTRACT This paper studies the impact of the adoption of different management control practices (MCP) on the firms’ financial performance in Latin America. We use the perspective of the attention-based view theory to argue that firms adopting MCP that cover different areas are more likely to attain higher financial performance, as adopting a diverse set of control practices contributes to distributing managerial attention. Thus, relevant business areas are monitored more comprehensively. We compare the performance effect of seven MCP in three areas (monitoring, operations, and targets) alone and combined using a panel dataset on 57 Latin American firms from 1995 to 2016, finding support for our arguments. Moreover, we find that the firms’ strategy moderates the financial performance effect of the adoption of MCP.
Probabilistic projections of future warming and climate sensitivity trajectories

Projections of future global mean surface warming for a given forcing scenario remain uncertain, largely due to uncertainty in the climate sensitivity. The ensemble of Earth system models from the Climate Model Intercomparison Project phase 6 (CMIP6) represents the dominant tools for projecting future global warming. However, the distribution of climate sensitivi-ties within the CMIP6 ensemble is not representative of recent independent probabilistic estimates, and the ensemble contains signiﬁcant variation in simulated historic surface warming outside agreement with observational datasets. Here, a Bayesian approach is used to infer joint probabilistic projections of future surface warming and climate sensitivity for shared socio-economic pathway (SSP) scenarios. The projections use an efﬁcient climate model ensemble ﬁltered and weighted to encapsulate observational uncertainty in historic warming and ocean heat content anomalies. The probabilistic projection of climate sensitivity produces a best estimate of 2.9 (cid:2) C, and 5th–95th percentile range of 1.5–4.6 (cid:2) C, in line with previous estimates using multiple lines of evidence. The joint projection of surface warming over the period 2030–40 has a 50% or greater probability of exceeding 1.5 (cid:2) C above preindustrial for all SSPs considered: 119, 126, 245, 370 and 585. Average warming by the period 2050–60 has a > 50% chance of exceeding 2 (cid:2) C for SSPs 245, 370 and 585. These results imply that global warming is no longer likely to remain under 1.5 (cid:2) C, even with drastic and immediate mitigation, and highlight the im-portance of urgent action to avoid exceeding C
Occupational justice in direct-funded attendant services: Possibilities and constraints

ABSTRACT In direct-funded attendant services, public funds are transferred to service users to recruit, hire, train, and manage support staff. An outcome of activist efforts to deinstitutionalize support services, direct funding models are often said to increase the choice and control that disabled people have in their attendant services and in everyday life. Focusing on one direct funding program in Ontario, Canada, the overarching reflexive ethnographic study explored the work that physically disabled adults contribute to organize and manage their own attendant services. In this paper we present a secondary analysis of qualitative interview data, examining the impact of participation in direct funding on service users’ occupational engagement. The results of this analysis suggest that direct funding promotes occupational rights by providing supports needed to participate in a range of meaningful occupations. At the same time, occupational engagement was found to be constrained at individual and group levels. In this paper we apply occupational justice concepts to analyze systemic constraints on occupational engagement and occupational choice, including program eligibility criteria and societal factors that condition access to and use of public resources. The discussion highlights how direct funding can support occupational engagement and constrain occupational choice, illuminating the complexity of occupational justice as a dynamic concept that may be promoted and obstructed simultaneously within a given context. We situate direct funding within an ongoing history of institutionalized supports for disabled people and identify specific factors that may promote or inhibit the occupational rights of disabled people who use direct-funded attendant services.
Modelling the effect of acoustic waves on the thermodynamics and kinetics of crystal nucleation from a solution

A phase transformation in a metastable solution can be affected when it is subjected to high-intensity acoustic waves. Despite the extensive experimental evidence, the nature of this phenomenon has been little studied theoretically. This work aims to tackle this issue and develop the theoretical basis for investigating the thermodynamics and kinetics of crystallisation induced by an acoustic field. In the first part of thesis, we investigated the effect of acoustic waves on the thermodynamics of crystallisation by the aid of the Gibbs droplet model in a generic format. We have developed a new model based on non-equimolecular clusters which can overcome some of the shortcomings of the conventional form of the classical nucleation theory (CNT) in describing the thermodynamics of small clusters. The model is validated by comparing the predicted kinetics of water droplet formation from the gas phase against experimental data. Our results demonstrate a close agreement with experimental data, better than predictions by CNT. In the second part, we studied the kinetics of phase transformation in an acoustic field. We developed a master equation based on a hybrid Szilard-Fokker Planck model, which accounts for mass transportation due to acoustic waves. This model is employed to determine the kinetics of nucleation and the early stage of growth of clusters including the Ostwald ripening phenomenon in an isothermal sonocrystallisation process and is solved numerically for different scenarios in a system with and without mass transportation. Our results show that the effect of pressure on the kinetics of nucleation is cluster size-dependent in contrast to CNT. Furthermore, we calculated mass transportation for different excitations modelled as plane waves propagating in a semi-infinite medium which tends to be rather noticeable only in the case of shock waves. The derivations are generic and can be used with any acoustic source and waveform.
Electricity Markets during the Liberalization: The Case of a European Union Country

This paper analyzes electricity markets in Slovenia during the specific period of market deregulation and price liberalization. The drivers of electricity prices and electricity consumption are investigated. The Slovenian electricity markets are analyzed in relation with the European Energy Exchange (EEX) market. Associations between electricity prices on the one hand, and primary energy prices, variation in air temperature, daily maximum electricity power, and cross-border grid prices on the other hand, are analyzed separately for industrial and household consumers. Monthly data are used in a regression analysis during the period of Slovenia’s electricity market deregulation and price liberalization. Empirical results show that electricity prices achieved in the EEX market were significantly associated with primary energy prices. In Slovenia, the prices for daily maximum electricity power were significantly associated with electricity prices achieved on the EEX market. The increases in electricity prices for households, however, cannot be explained with developments in electricity prices on the EEX market. As the period analyzed is the stage of market deregulation and price liberalization, this can have important policy implications for the countries that still have regulated and monopolized electricity markets. Opening the electricity markets is expected to increase competition and reduce pressures for electricity price increases. However, the experiences and lessons learned among the countries following market deregulation and price liberalization are mixed. For industry, electricity prices affect cost competitiveness, while for households, electricity prices, through expenses, affect their welfare. A competitive and efficient electricity market should balance between suppliers’ and consumers’ market interests. With greening the energy markets and the development of the CO2 emission trading market, it is also important to encourage use of renewable energy sources.
Renewable Energy, Economic Growth and Economic Development Nexus: A Bibliometric Analysis

The present research aims to conduct a systemic review on Renewable Energy, Economic Growth and Economic Development and look for links between the papers published between 2008 and May 2021. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, it was possible to reach a sample of 111 articles selected by Web of Science and a sample of 199 academic articles selected by Scopus in that specific period. The analysis of the group of Renewable and Non-renewable Energy Consumption, Economic Growth and Economic Development shows that most of the articles published in this subsample use the quantitative methodology in economic sciences. The results indicate that research on the subject has a growing trend and that most of the articles are post-2015 publications. In addition, China has been the leading nation in published works. The journal Renewable and Sustainable Energy Reviews is considered the most relevant in this category, and Sustainability has the most publications. Finally, a research gap was identified to be explored, lacking studies aimed at understanding the consumption of renewable energies and economic development and studies that focus on renewable energies and economic growth in less developed economies.
