Authors: Danova Karyna , Malysheva Viktoriia , Rosokha Volodymyr , Glushenkova Irina , Popovych Nataliia 
Published: February 2020

It is impossible to ensure sustainable business development without solving the maintenance of labor resources issues that are included in the manufacturing process, as well as involving new employees to increase labor potential. The company can effectively confront the new challenges by attracting highly qualified employees for whom a high level of safety is important. Therefore, an important direction of sustainable business development is to increase the level of safety and create a comfortable working environment and optimize working processes to increase the efficiency of production activities, as well as prepare for the challenges that may arise in the process of company development. The article analyzes the statistics and structure of the socio-economic damage to business due to unsatisfactory working conditions and a high level of injuries on the example of the machine-building sector, and also considers aspects of maintenance of labor resources and ways to involve additional labor resources to ensure sustainable manufacturing development. Based on conducted analysis, an algorithm of implementation of managerial decisions was developed, aimed at ensuring the safety of personnel who carry out the work activities at the workplace, taking into account the modern concept of the “green workplace”. Involvement in the working process of additional labor reserves is carried out by creating favorable working conditions, assessing the special needs and level of ability of workers for optimization of working processes and increasing their efficiency.

Sustainable Product Portfolio Evaluation Methodology for Sustainability Reporting in the Cement and Concrete Industry
Authors: Artelt Christian , Lukas Peter 
Published: February 2020

The sustainability performance of companies, and in particular of construction material producers, is attracting more and more attention by a broad range of stakeholders. Many companies have consequently started to implement sustainability practices into practical action and to report on their efforts. This research aims to develop a methodology to assess the sustainability performance of cement and concrete products. This requires overcoming the main shortage of life cycle assessment, namely focusing on environmental parameters only, by considering a number of social and economic sustainability indicators and ensuring operational ease, without compromising the informative value of the assessment results. A status on sustainable product evaluation is provided as the starting point for the development of the new sustainable product evaluation methodology. The status on product evaluation includes Life Cycle Assessments, the development of indicators addressing environmental, social, and economic parameters, and recent methodology developments in industry. The results obtained with the tool developed in this work confirm the need for considering social and economic parameters along a product’s life cycle when evaluating the sustainability performance of cement and concrete. They also indicate that the new methodology is suitable for R&D orientation, portfolio management and sustainability reporting.

According to the U.S. Bureau of Labor Statistics, the U.S. economy is experiencing an unemployment rate that is at a fifty-year low. Yet, wage growth continues to be weak, with continuing wage stagnation even at the peak of the business cycle. A major and largely undertheorized reason for the sluggish wages in a period of seeming full employment is to be found in the fact that the new jobs being created by the economy do not measure up to those of the past in terms of weekly wages and hours, or in the degree to which they support households or even individuals.
Supplier selection under strategic decision environment
Authors: Jana Prithwiraj 
Published: February 2020

The world is becoming more and more a global marketplace and the global environment is forcing companies to take almost everything into consideration at the same time. Increase flexibility is needed to remain competitive and respond to rapidly changing markets. an effective supplier selection process is very important to the success of any organization. Supplier selection represents one of the most important decisions in a company to remain competitive, In this context, supplier selection represents one of the most important functions to be performed by the purchasing department. The supplier selection is a multi-criterion problem which includes both qualitative and quantitative factors (criteria). In order to select the best supplier it is necessary to make a tradeoff between these tangible and intangible factors some of which may conflict. This report deals with the supplier selection where a state of the art is presented. The supplier selection process deploys a tremendous amount of a ﬁrm’s ﬁnancial resources. In return, ﬁrms expect signiﬁcant beneﬁts from contracting with suppliers offering high value.
Investment in Green Technology and Entry Deterrence
Authors: Strandholm John C. , Espínola-Arredondo Ana 
Published: February 2020

Abstract
This paper analyzes an entry-deterrence model in which the incumbent decides whether to invest in research and development (R&D) that promotes clean technology. We consider the case in which the entrant could benefit from a technology spillover and analyze the conditions that facilitate the incumbent’s entry-deterrence behavior. We show that higher levels of the spillover make entry more attractive compared to a standard entry game. In addition, regulator and incumbent prefer entry when the spillover from clean technology is sufficiently high and the cost of investing in R&D is relatively low. However, preferences are misaligned when the spillover and cost of R&D are low.
Microfinance and Vulnerability to Seasonal Famine in a Rural Economy: Evidence from Monga in Bangladesh
Authors: Berg Claudia , Shahe Emran M. 
Published: February 2020

Abstract
This paper uses a unique data set on 143,000 poor households from Northern Bangladesh to analyze the effects of microfinance membership on a household’s ability to cope with seasonal famine known as Monga. We develop an identification and estimation strategy that exploits a jump and a kink at the 10-decimal land ownership-threshold driven by the Microfinance Institution screening process to ensure repayment by excluding the ultra-poor. Evidence shows that microfinance membership improves food security during Monga, especially for the poorest households who survive at the margin of one and two meals a day. The positive effects on food security are, however, not driven by higher income, as microcredit does not improve the ability to migrate for work, nor does it reduce dependence on distress sale of labor. The evidence is consistent with consumption smoothing being the primary mechanism behind the gains in food security of MFI households during the season of starvation.
The Consequences of the 1959–1961 Chinese Famine for Educational Attainment
Authors: Lay Margaret J. , Norling Johannes 
Published: February 2020

Abstract
This paper finds that the Great Chinese Famine of 1959–1961 reduced lifetime educational attainment by up to 3.8 years for people who lived in areas most severely hit by the famine. Using geographical variation in famine intensity, information about place of residence during the famine, and educational attainment recorded in the China Health and Retirement Longitudinal Study, the paper demonstrates that the decline in educational attainment was particularly sharp for women. This decline interrupted substantial gains in schooling achieved in China during the middle part of the twentieth century.
Accounting for Differences in Female Labor Force Participation between China and India
Authors: Azam Mehtabul , Han Luyi 
Published: February 2020

Abstract
Although, the male labor force participation rate is comparable in China and India, female labor force participation rate remains very low in India. In this paper, we examine the factors responsible for the difference in female labor force participation rate between the two countries by carrying out decomposition exercise at three points of time covering two decades. We find that the differences in female labor force participation rate are not explained by the differences in characteristics across the two countries in each of the three year studied. The differences in returns to these characteristics explain most of the differences in participation rate.
The Effects of Entry when Monopolistic Competition and Oligopoly Coexist
Authors: Fujiwara Kenji 
Published: February 2020

AbstractThis paper proposes a model of a continuum of industries in which some industries are monopolistically competitive, the others are oligopolistic, and they interact in a labor market. We use this model to examine the effects of entry of oligopolistic firms. We show that this raises the equilibrium wage and induces exit of monopolistically competitive firms. Then, we find that the profits of each oligopolistic firm and the whole oligopolistic industry decrease. Finally, we establish that if the elasticity of substitution is the same in all industries, welfare improves as a result of an increase in the oligopolistic firms.
Pretrial Beliefs and Verdict Accuracy: Costly Juror Effort and Free Riding
Authors: Guha Brishti 
Published: February 2020

AbstractIf jurors care about reaching the correct verdict, but also experience costs to paying attention during the trial, even a small effort cost generates interesting interactions between pretrial beliefs and verdict accuracy. I demonstrate the existence of a strong free riding effect; jurors respond to a more informative prior by reducing their probabilities of paying attention, to the extent that over a non-empty range, a more informative prior will be associated with poorer verdicts. Pretrial beliefs can depend on several factors: I consider two – the extent of discovery during the pre-plea bargaining process, and the efficiency of the police. My results imply that more liberal discovery rules, which result in a less noisy plea bargaining process, will actually be complemented by greater juror effort over a range, resulting in more accurate verdicts. In contrast, greater police efficiency will, over a range, elicit a sufficient drop in juror effort such that verdicts are less accurate. Thus, improving discovery has added benefits over a range, while the benefits of exogenous improvements in policing may be dampened. I briefly extend the model to cases where attentive jurors receive an imperfect public signal instead of a perfect one, and to cases where jurors’ utilities from convicting a guilty defendant differ from their utilities from acquitting an innocent one.
Product R&D Coopetition and Firm Performance
Authors: Ramsza Michał , Karbowski Adam 
Published: February 2020

AbstractWe investigate firms’ behavior in demand-enhancing product R&D. We consider and compare a cooperative and non-cooperative R&D investment setting by firms. In a non-cooperative scenario (R&D competition), firms decide on their R&D investments and outputs unilaterally. In a cooperative scenario (R&D coopetition), firms engage in a bargaining process to reach a binding R&D agreement. Firms through bargaining can reach an R&D agreement which specifies their R&D investment levels. The investment levels under R&D coopetition are higher compared with the investment levels under R&D competition. Firms’ profits are also higher under R&D coopetition compared with R&D competition. We conclude that R&D coopetition can alleviate the individual R&D investment disincentive and work as a strategic instrument that enhances product innovation and firms’ profits.
Edaravone exerts brain protective function by reducing the expression of AQP4, APP and Aβ proteins

Published: February 2020

AbstractThis study aims to investigate the changes of aquaporin-4 (AQP4), β-amyloid precursor proteins (APP) and β-amyloid (Aβ) in brain tissues after cerebral ischemiareperfusion injury (CIRI), and evaluate the effect of edaravone. The Middle Cerebral Artery Occlusion was used to establish CIRI in rats. Rats were divided into control, model and edaravone groups. The neurological deficits in the model group were obvious and the neurological score increased compared to the control group, while the neurological deficits of the edaravone group were improved as the neurological score decreased compared to the model group. The number of pyramidel cells in the hippocampus of the model group was significantly decreased whereas edaravone could reverse this decrease. The model group had significantly higher levels of Aβ, APP and AQP4 than the control group and edaravone group, suggesting that they might be involved in the neuronal cell damage. Meanwhile, the increased AQP4 might enhance the permeability of cells, and thus cause cell damage and neurological deficit. Conclusively, edaravone could reduce brain edema, protect neuronal cells and improve the neurological impairment of rats possibly by decreasing the expression of Aβ, APP and AQP4. Therefore, edaravone may have the potential to treat neurodegenerative diseases (such as Alzheimer's disease).
Cognition in construction grammar: Connecting individual and community grammars
Authors: Anthonissen Lynn 
Published: February 2020

AbstractThis paper examines, on the basis of a longitudinal corpus of 50 early modern authors, how change at the aggregate level of the community interacts with variation and change at the micro-level of the individual language user. In doing so, this study aims to address the methodological gap between collective change and entrenchment, that is, the gap between language as a social phenomenon and the cognitive processes responsible for the continuous reorganization of linguistic knowledge in individual speakers. Taking up the case of the prepositional passive, this study documents a strong community-wide increase in use that is accompanied by increasing schematicity. A comparison of the 50 authors reveals that regularities arising at the macro-level conceal highly complex and variable individual behavior, aspects of which may be explained by studying the larger (social) context in which these individuals operate (e. g., age cohorts, community of practice, biographical insights). Further analysis, focusing on how authors use the prepositional passive in unique and similar ways, elucidates the role of small individual biases in long-term change. Overall, it is demonstrated that language change is an emergent phenomenon that results from the complex interaction between individual speakers, who themselves may change their linguistic behavior to varying degrees.
Meeting the Assumptions of Inverse-Intensity Weighting for Longitudinal Data Subject to Irregular Follow-Up: Suggestions for the Design and Analysis of Clinic-Based Cohort Studies
Authors: Pullenayegum Eleanor M. 
Published: February 2020

Abstract
Clinic-based cohort studies enroll patients on first being admitted to the clinic, and follow them as part of usual care, with interest being in the marginal mean of the outcome process. As the required frequency of follow-up varies among patients, these studies often feature irregular visit times, with no two patients sharing a visit time. Inverse-intensity weighting has been developed to handle this, however it requires that the visit process be conditionally independent of the outcome given the observed history. When patients schedule visits in response to changes in their health (for example a disease flare), the conditional independence assumption is no longer plausible, leading to biased results. We suggest additional information that can be collected to ensure that conditional independence holds, and examine how this might be used in the analysis. This allows clinic-based cohort studies to be used to determine longitudinal outcomes without incurring bias due to irregular follow-up.

AbstractA series of substituted 4H-pyrans derivatives were synthesized by a one-pot, multi-component reaction of aromatic aldehydes, malononitrile, and pyrazolone derivatives or active methylene carbonyl compounds such as dimedone, in the presence of 1,3-dimethyl imidazolium dimethyl phosphate [DMImd-DMP] as a catalyst in aqueous ethanol. Recyclability of the catalyst, high yields, simple product isolation and high atom economy are the noteworthy aspects of this protocol.
A Coordinated Voltage Control Scheme of Distribution Networks with Distributed Generation Based on On-Load Tap Changers and Shunt Capacitors by Particle Swarm Optimization
Authors: Nguyen Minh Y 
Published: February 2020

AbstractRecently, the voltage stability and control of distribution networks become challenges due to the large line impedance, load variations and particularly the presence of distributed generation. This paper presents a coordinated voltage control scheme of distribution systems with distributed generation based on on-load tap changer and shunt capacitors. The problem is to determine the optimal operation of voltage regulation devices to minimize a multi-objective function including power losses, voltage deviations and operation stresses while subject to the allowable voltage ranges, line capacity and switching stresses, etc. The problem is formulated and solved by a modified particle swarm optimization algorithm to treat the large-scale and high nonlinearity property. The proposed scheme is applied to a typical 48-bus distribution network in Vietnam. The result of simulation shows that the voltage profile can be improved while the power loss of distribution systems can be reduced significantly.

Published: February 2020

AbstractThe aim of this work was to study the influence of freeze-drying conditions of kiwi (Actinidia deliciosa) on physicochemical properties and grinding characteristics of dried fruits. Whole kiwi fruits were freeze-dried with the different pressure: 12, 20, 42, 63, 85, and 103 Pa. Dried fruit properties that underwent evaluation included color, texture, rehydration, total phenolics content, antioxidant properties and sensory analysis. Moreover, the grinding energy indices of dried kiwi were determined. The results showed that an increase in the pressure caused decreased lightness, but increased yellowness and greenness of freeze-dried kiwi. The force of kiwi penetration increased and the rehydration ability decreased with the increase in the pressure. The specific grinding energy of dried kiwi ranged from 10.1 to 13.6 kJ⋅kg−1, whereas the average particle size of kiwi powder changed from 0.331 to 0.337 mm. The highest values of these parameters were obtained for kiwi freeze-dried with the highest pressure.

Published: February 2020

AbstractInconel 718 is a nickel-based superalloy which finds major applications in lightweight welded frames and other parts in gas turbine engines. This alloy is frequently joined by gas tungsten arc welding (GTAW) process for clean and precise welds. However, the weldability of Inconel 718 alloy is limited by the high heat input and slower cooling rate in GTAW process. It leads to the segregation of alloying elements and detrimental laves phase formation in weld metal which significantly reduces the tensile properties of the welded joints. To overcome this problem, a newly developed gas tungsten constricted arc welding (GTCAW) process is used for joining Inconel 718 alloy. The main effect of Delta Current (DC) and Delta Current Frequency (DCF) on the tensile properties and microstructure of GTCA welded 2 mm thick Inconel 718 alloy sheets was investigated. Superior tensile properties were exhibited at Delta Current of 50 A and Delta Current Frequency of 4 kHz due to the refinement in fusion zone. Delta Current and Delta Current Frequency showed deleterious effect at higher levels due to the high heat input.
Composite filler by pre-flocculation of fiber fines and PCC and its effect on paper properties
Authors: Kang Hyun , Won Jong Myoung , Cho Byoung-Uk 
Published: February 2020

AbstractA composite filler was developed by pre-flocculation of fiber fines and precipitated calcium carbonate (PCC) particles with flocculants such as cationic polyacrylamide (cPAM) and bentonite. The composite filler was compared with a conventional loading method in terms of physical properties of handsheet and filler retention. The handsheets using the composite filler showed higher strength properties than that using a conventional loading at a similar paper ash content level, implying that paper ash content can be increased maintaining same level of paper strength. Optical properties such as opacity and brightness of the paper with the composite were quite similar with the paper with the conventional loading. Filler retention of the composite filler was slightly higher than that of the conventional loading even though retention aids were not used for the composite filler. Paper formation of the composite filler was better than the case of the conventional loading. However, the sheet with the composite filler showed lower bulk than that with the conventional loading. Conclusively, the composite filler technology by pre-flocculation of fines and filler has a potential to be utilized to produce a high loaded paper.
The influence of process parameters of screen-printed invasive plant paper electrodes on cyclic voltammetry

Published: February 2020

AbstractUsing disposable screen-printed electrodes is a convenient way of monitoring environmental pollution, production process control etc. Usually, commercially available screen-printed electrodes are used, but more and more studies are being carried out in the field of printing electrodes on thinner, low-cost and versatile substrates, including paper. In the present research, the comparison of screen-printed electrodes printed on different paper-based materials is presented. Two unique and innovative invasive plant-based papers made from (1) Japanese knotweed, (2) Canadian and Giant goldenrod and (3) commercially available cardboard were used as a printing material for the electrodes. The selected paper substrates were characterized, and screen-printed electrodes were printed. The influence of substrates’ properties and pre- or post-treatment of the screen-printed electrodes on the electrochemical behaviour is thoroughly analyzed. The results indicate that the printing substrate (roughness) had the most significant influence on the cyclic voltammetry response. Comparing pre- and post-treatment of screen-printed electrodes, it was shown that grinding influenced the electrochemical activity significantly, while corona discharge does not have as significant influence. Besides, it was shown that the invasive plant-based papers are viable alternatives to commercially available papers and can be used as low-cost and eco-friendly alternatives for disposable screen-printed electrodes.
