Authors: Nascimento Juracy Leandro do , Copetti Alessandro , Bertini Luciano , Moratori Patrick Barbosa , Campos Mário Cesar Mello Massa de 
Published: June 2019

Goal: Industry 4.0 enables the design of new models for process monitoring in which sensors, analyzers, and controls are positioned at different points in the process. The goal of this work is to present the modeling and control of a three-phase production separator with hydrocyclones to treat produced water on an oil platform of mature fields.
Design / Methodology / Approach: The Methodology or approach used was to develop a model for the primary separator that allows its operation by means of a controller (fuzzy and PI) to manipulate the flow of discarded water, acting indirectly in the oil-in-water measure.
Results: The results showed the consistency of the model for open loop simulations and the effectiveness of the controllers to comply with the discarding requirements for the closed-loop simulations.
Limitations of the investigation: The limitation of the model and developed controllers is that they are only applied to platforms where water production exceeds the separators discharge capacity and the exceeding water can be offloaded to another equipment or to another platform.
Practical implications: The main practical implications of this study are to maximize the flow of discarded water on mature field platforms, which produces elevated amounts of water, to conform the total oil and grease to the local law regulations. Additionally, it also increases oil production, with a higher limit of water production.
Originality / Value: Compared to the previous authors, where the models of discarded flow is a function of the water-oil interface, this work developed a model that allowed the flow of the discarded water to be a function of its quality.

Published: June 2019

Highlights: A brief review of industrial, logistics, and Supply Chain Management evolution. A concept and the technological elements for Supply Chain Management 4.0 (SCM 4.0) are presented. Potential applications of SCM 4.0 are reviewed as well.
Goal: This paper aims at reviewing the historical development of the Supply Chain Management 4.0 concept and to propose an update for it.
Design/Methodology/Approach: The exploratory part of the paper started with a bibliometric analysis to identify relevant keywords and publications per year. Secondly, a historical review of the concepts of Supply Chain Management is presented. Additionally, the paper embraced a conceptual approach to propose a new definition of Supply Chain Management 4.0. Lastly, a research outlook and some initiatives to the practical application of the concept are presented.
Results: The bibliometric analysis about Supply Chain Management 4.0 reinforce the growing importance of the topic. The main keywords related to the subject indicate that Big Data, cloud computing, and Internet of Things are the most widely explored issues within smart supply chains. Analysis indicate that smart supply chains take advantage of communication and technological advances in order to build an adaptive, efficient, and transparent network. However, the application of such concept requires the development of knowledge, not only in the hardware and software fields, but also in the managerial field, to address the question of how to use that information and communication to benefit stakeholders.
Limitations of the investigation: The document reports an exploratory research applied only to the Scopus database. In addition, only English-language literature was considered.
Practical implications: The review showed a lack on the development of knowledge not only in the hardware field, but also in the managerial field. It is recommendable that studies focus on areas such as required data to be exchanged, potential financial benefits, and technological and managerial challenges.
Originality/value: An overview of the historical evolution of the supply chain to the Supply Chain Management 4.0 is presented. A concept of Supply Chain Management 4.0 is proposed. Application examples illustrated the practical implementation of the proposed concept.

Authors: Roy Supriyo , Satpathy Biswajit 
Published: June 2019

Goal: This Survey-based empirical research is aimed to theorize and assess a structural model that incorporates strategic alliance between Information Intensive Services (IIS) and Supply Chain Integration (SCI) and its impact on Firm Performance (FP), with special reference to Indian business houses.
Design / Methodology / Approach: This paper proposes a hypothesis model within the decision-making framework that offers strategic alliance tool for managers in the area of supply chain to operationalize business decisions. Samples of more than 210 primary data sets are collected from population of different industries in India by a proper sampling method and by framing questionnaires. The relationship, as proposed in the hypothesis model, is assessed empirically by using statistical techniques called Structural Equation Modeling.
Results: Practitioners may expect improved supply chain performance through strategic alliance between information intensive services and supply chain integration, as it is demanded industries in this Industry 4.0 era.
Limitations: The hypothesis framed by western standards seems to be obvious; however, considering the Indian business scenario, where the supply chain and technology of information systems are almost a new concept in most firms, this seems to be a valid area of research.
Practical Implications: Research conceptualizes and develops different dimensions of information-intensive services that offer empirical support for the adoption of proper information system to improve performance within an integrated supply chain.
Originality / Value: This survey-based empirical research will ‘coordinate and highlight the issue of integration’ of Enterprise Information Systems within the organizational supply chain.

Authors: Natrajan Nidhi Shridhar , Sanjeev Rinku , Singh Sanjeev Kumar 
Published: June 2019

In present scenario, business organization understood the importance of sophisticated employee behavior for the development of overall job performance. It is important for an organization to perform effectively for that it enhances their employee’s job performance. Many study supports that an empowered employee recognizes and attaches himself or herself with the wider extent of organizational objectives. An engaged employee has more ownership and able to contribute towards his/her own growth and overall productivity. Boston focuses on implementing feedback given by employees with immediate effect and has 43% employees who are highly engaged. Facebook has a culture of contribution and each employee is recognized for his contribution to the overall goal of the company “to make the world more open and connected ". This policy of contributing culture is communicated to all the candidates during recruitment process. That is why Facebook is not only known for being one of the most popular social networking platforms but for its highly engaging culture as well. Under this study, the focus is to understand the relationship between employee empowerment and job performance. The study also tries to explore empirically the mediating effect of employee engagement in this regard. It was conducted on IT sector in Delhi NCR region with a sample size of 182 employees. The finding of the study reflects that engagement has its mediation effect on job performance with respect to employee empowerment.
Risk Taking and Aggression On and Off the Field: Evidence from the National Football League
Authors: Ge Qi 
Published: June 2019

Abstract
We study the behavioral link between NFL players’ off-field misconduct and their on-field infractions by matching a comprehensive dataset of players’ off-field arrests with detailed record of on-field penalty calls. Results from Poisson regressions indicate that players with arrest record are likewise observed to have significantly higher tendencies for aggression-related penalties, implying their inherent preferences toward risks or aggression. Such association is particularly salient among repeat offenders. We also find that repeat offenders boast stronger overall career performance and longer career span compared to non-offenders and one-time offenders, suggesting that the related behavioral traits can be instrumental to job performance in professional football.
Endogenous Matching and Money with Random Consumption Preferences
Authors: Hogan Thomas L. , Luther William J. 
Published: June 2019

Abstract
Current money matching models employ either random matching or endogenous matching processes, both of which oversimplify the problem. We maintain that, although most economic interactions are intentional, some randomness remains. We offer an endogenous matching model of money with random consumption preferences. Our model preserves the intentionality of economic interactions while leaving scope for chance. We identify the conditions for potential monetary and nonmonetary equilibria and compare them to those of other endogenous matching and random matching models.

Abstract

Background
Familial hypercholesterolemia (FH) is a genetic disorder caused by mutations in genes involved in low-density lipoprotein (LDL) uptake (LDLR, APOB and PCSK9). Genetic diagnosis is particularly useful in asymptomatic children allowing for the detection of definite FH patients. Furthermore, defining their genetic status may be of considerable importance as the compound heterozygous status is much more severe than the heterozygous one. Our study aims at depicting the genetic background of an Italian pediatric population with FH focusing on the correlation between lipid profile and genetic status.

Methods
Out of 196 patients with clinically suspected FH (LDL-cholesterol [LDL-C] levels above 3.37 mmol/L, cholesterol level above 6.46 mmol/L in a first-degree relative or the presence of premature cardiovascular acute disease in a first/second-degree relative), we screened 164 index cases for mutations in the LDLR, APOB and PCSK9 genes.

Results
Patients with mutations (129/164) showed increased levels of LDL-C, 95th percentile-adjusted LDL-C and LDL/high-density lipoprotein (HDL) ratio and decreased levels of HDL-C, adjusted HDL-C. The association of the LDL/HDL ratio with the presence of mutations was assessed independently of age, (body mass index) BMI, parental hypercholesterolemia, premature coronary artery disease (CAD), triglycerides by multivariate logistic regression (odds ratio [OR]=1.701 [1.103–2.621], p=0.016). The LDL/HDL ratio gradually increased from patients without mutations to patients with missense mutations, null mutations and compound heterozygotes.

Conclusions
In conclusion, the LDL/HDL ratio proved to be a better parameter than LDL-C for discriminating patients with from patients without mutations across different genetic statuses.

Abstract

Background
Thyroid hormone levels are essential for diagnosing and monitoring thyroid diseases. However, their reference intervals (RIs) in elderly Chinese individuals remain unclear. We aimed to identify factors affecting thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) levels using clinical “big data” to establish hormone level RIs for elderly Chinese individuals.

Methods
We examined 6781, 6772, and 6524 subjects aged ≥65 years who underwent FT3, FT4, and TSH tests, respectively, at the Peking Union Medical College Hospital between September 1, 2013, and August 31, 2016. Hormones were measured using an automated immunoassay analyzer (ADVIA Centaur XP). RIs were established using the Clinical Laboratory Standards Institute document C28-A3 guidelines.

Results
The median TSH was significantly higher in women than in men; the opposite was true for median FT3 and FT4 levels. No differences were observed in TSH or FT4 by age in either sex or overall; FT3 levels significantly decreased with age. Seasonal differences were observed in TSH and FT3 levels but not FT4 levels; the median TSH was the highest in winter and lowest in summer, whereas the median FT3 was the lowest in summer (albeit not significantly). RIs for TSH were 0.53–5.24 and 0.335–5.73 mIU/L for men and women, respectively; those for FT3 were 3.76–5.71, 3.60–5.42, and 3.36–5.27 pmol/L in 64- to 74-, 75- to 84-, and 85- to 96-year-old subjects, respectively. The RI for FT4 was 11.70–20.28 pmol/L.

Conclusions
RIs for TSH in elderly individuals were sex specific, whereas those for FT3 were age specific.

Abstract

Background

Helicobacter pylori has been associated with iron deficiency (ID). This study is aimed at investigating ID with conventional (ferritin, transferrin saturation [TSAT]) and new biomarkers (soluble transferrin receptor [sTfR], sTfR/log ferritin, reticulocyte hemoglobin content [CHr], hepcidin-25) in patients sub-grouped by the presence or absence of H. pylori infection.

Methods
In total, 200 consecutive outpatients, who were referred for the H. pylori
13C-urea breath test (13C-UBT), underwent blood testing for ID. Additionally, Thomas-plot (TP)-analyses (sTfR/log ferritin, CHr) were calculated.

Results
Fifty-three and 147 individuals were found with and without H. pylori infection, respectively. Patients with H. pylori infection showed a higher sTfR concentration (p<0.02) and a higher sTfR/log ferritin ratio (p<0.05). Based on a ferritin <30 μg/L and/or a TSAT <20%, 25/53 (47.2%) patients with H. pylori infection and 63/147 (42.9%) without H. pylori infection showed ID. Based on TP-analyses, 10/53 (18.9%) patients with and 17/147 (11.6%) without H. pylori infection were identified with ID. Completed eradication therapy tended to be associated with functional ID.

Conclusions

Helicobacter pylori infection was associated with significantly higher plasma sTfR concentrations and sTfR/log ferritin ratios. Patients with H. pylori eradication therapy were more often detected with functional ID compared to patients without eradication therapy, when using the new biomarkers.

Published: June 2019

Abstract
In this paper, we introduce a new generalization of λ-Bernstein operators based on q-integers, we obtain the moments and central moments of these operators, establish a statistical approximation theorem and give an example to show the convergence of these operators to f(x). It can be seen that in some cases the absolute error bounds are smaller than the case of classical q-Bernstein operators to f(x).
