Identification and Profiling of Microbial Community from Industrial Sludge

This study aims to identify microbial communities and their taxonomical profiling basis of order, species, genus, family, and class at the level in the sludge of pulp and paper industry. Studies showed dominant phyla in 16S rDNA Illumina Miseq analysis inside sludge were Anaerolinea, Pseudomonas, Clostridia, Bacteriodia, Gammaproteobacteria, Spirochetia, Deltaproteobacteria, Spirochaetaceae, Prolixibacteraceae and some unknown microbial strains are also dominant. The results of metabarcoding of the V3-V4 16S rRNA regions acquired from paired-end Illumina MiSeq sequencing were used to analyze bacterial communities and structure. Microorganisms can produce a vast variety of secondary metabolites, all of which are playing a crucial in biogeochemical cycle processes. The present work demonstrates the potential approach to sludge treatment in the open environment via the naturally adapted microorganism, which could be an essential addition to the disposal site. In summary, these investigations indicate that the indigenous microbial community is an acceptable bioresource for remediation or detoxification following secondary treatment. This research aims at understanding the structure of microbial communities and their taxonomic diversity (%) in highly contaminated sludge to perform in-situ bioremediation.

Icarus of the 21st century: bond/monoline insurance

Purpose The business model of monoline insurers is to guarantee payments of debt issues in case of defaults by the issuer. Although sparse attention is given to monolines in literature, they play an important role in enabling municipalities and firms in refinancing. This study aims to conduct a systematic review of 181 articles from 1990 to 2020 from 23,130 records and a case study on the key monoline insurers. Key failure, success factors and demand for future monoline insurance are identified. Finally, the study explores monolines’ potential during COVID-19 and develops a framework for monoline governance and regulation. Design/methodology/approach The study follows Briner and Denyer and Moher et al. to implement the systematic review. The methodology involves ascertaining the motivation behind the review, and formulating research questions; aggregating relevant prior literature from scientific databases, conducting quality assessment and synthesising the data; and conducting extensive analysis for framework development. Case study methodology foundation phase focuses on understanding the research philosophy. The second phase involves documenting the procedures involved. The final phase involves collecting the relevant quantitative and qualitative material. In addition, collecting empirical data from numerous sources allows triangulation. Findings The review results of 181 articles from 1990 to 2020 show that peak article counts occur in 2010 and 2013 (nine academic studies) and in 2008 and 2010 (six industry studies). Over- and under-explored domains happen to be bond pricing (86 academic studies) and bond markets (36 industry studies) and corporate bonds (19 academic studies), respectively. The study highlights failure factors such as adverse selection, premiums mispricings, inadequate capital and regulation, untimely downgrades and governance issues; and identifies success factors such as conservative underwriting, early financing, competitor business acquisitions and obtaining put-back claims. Potential during COVID-19 is discussed and a monoline governance framework is developed. Research limitations/implications Search and selection criteria distortions may lead to sample selection bias in systematic reviews. Issue is addressed by using different permutations of the search key words to refine the search criteria. Reference list of collected final sample of articles are perused to identify additional articles. It is difficult to obtain verifiable empirical data on the bond/monoline insurers or their insured products, especially for the structured finance sector. Most of the information available on data stream and firm’s quarterly financial reports for publicly traded monoline/bond insurers and credit rating reports are included to overcome this issue. Practical implications Demand for bond/monoline insurance still persists even in the USA. Although borrowing costs are low, obtaining bank loans would be challenging for municipalities and corporates with increased risks. Especially, given worldwide government stimulus on wages, most municipalities would possess reduced budgets for public finance. Monoline insurance can play a key role in financing such projects. Thus, it is important to understand their unique traditional and transformed business model and applicability during and post-COVID-19. Given the near extinction of bond/monoline insurers during the 2008 global financial crisis (GFC), an adequate framework for bond/monoline insurers as developed in this study is key for future business continuity. Social implications There is significant interest, especially, from the industry on monolines as identified in our systematic review. Monoline insurance has major effects on taxpayers, government policies and bond investors. They aid in financing public finance projects that have significant societal impact. This study contributes by filling existing gaps in the literature, especially, from a behavioural, ethical and social perspective of the monolines, regulators, other stakeholders and new entrants to the industry during COVID-19. This study links prior finance theories to the impact of bond/monoline insurer’s during the 2008 GFC and their stakeholders involved that has societal implications. Originality/value This study can be differentiated from prior research on monoline insurers as follows: The study identifies, gaps, similarities, trends between prior academic and industry literature and develop a bond/monoline governance framework; identifies key failure and success factors during the 2008 GFC crisis to develop the governance framework and identify monolines’ potential during COVID-19; as opposed to most prior literature that only focus on one (Drake and Neal, 2011 analyse MBIA) or two key bond/monoline insurers, this study focuses on five key bond/monoline insurers in detail and all other key insurers as well in the empirical analysis section.

Taking Netflix to the Cinema: National Cinema Value Chain Disruptions in the Age of Streaming

This article explores how international over-the-top services impact the national feature film value chain in Canada and Australia. The main objective of this exploration is to interrogate the tendency to classify Netflix as television—whether in the context of broadcasting policy or in light of disciplinary biases that tend to separate media industry studies from the more cinephilic text-focused approaches of film studies. By equating entertainment services like Netflix with television, the discussion of how feature films will sustain themselves in a rapidly changing market becomes sidelined. Examining examples from Canada and Australia, we seek to draw attention to the ways in which film sustains and develops its industry and how services like Netflix relate to policy mechanisms designed to foster national cinema. This article offers an intervention into the developing discourse around Netflix as television to ask the question: what does it mean to consider Netflix as cinema?

Decarbonization Advancements in Pressure Pumping With Gas Turbines

Key changes have triggered the push for frac fleet innovation. With environmental regulation efforts to cut down on emissions increasing, more and more companies are transitioning to the use of electric fleet equipment. Electric fleets use natural gas, which burns cleaner than diesel fuel. Our study found the gas turbine outperformed Tier 4 dual fuel blend (DF) reciprocating engines and demonstrated a step change improvement in both direct and indirect emissions reductions over the 20+ year lifecycle of the Baker Hughes LM2500 in Permian and Williston Basins’ field operating conditions. An even greater impact to direct GHG (as CO2 equivalent) emissions reduction came to light when the potential to reduce flaring of associated gas was considered. Gas turbines have been proven to have the best-in-class emissions for powering pressure pumping fleets and lead the industry on fuel cost savings and in achieving commitments to reduce carbon emissions in places like the Permian Basin in Texas and remote areas across the world. Though, recent industry studies abominably suggest that Tier 4 diesel and Tier 4 dual fuel (DF) engine technologies offer an alternative with emissions benefits in comparison to current gas turbine offerings this study demonstrate the contrary.

Measuring Safety Climate in the Construction Industry: A Systematic Literature Review

Recent studies on safety in various fields use the concept of safety climate to explain the causes of safety accidents. Many studies attempt to measure the safety climates and identify the causes for accidents in the high-risk construction industry. Studies have shown that the higher the level of the safety climate, the lower the accident rate at construction sites. Methods of measuring safety climate, including the NOSACQ-50 survey, have been presented. Studies on the methodology of measuring safety climate should be continued to improve reliability and precision. Although many studies have been conducted to measure safety climate, such as questionnaires, regression analysis, and suggestions for safety climate measurement methods, there are few studies on a systematic literature review of them. This requires a systematic literature review (SLR) of the studies conducted so far. This study conducted an SLR on the definition and measurement methods of safety climate in the construction industry published since 2000, when safety climate’s impact on accidents began to be established. This review study utilized the PRISMA method, analyzed 735 studies, and selected 57 papers finally. SLR was carried out for selected research works, and the results were summarized. There are three methods to measure safety climate: literature survey, questionnaire, and data analysis. Factor analysis, development of measuring model, development of questionnaire, statistical analysis, and machine learning were investigated as their sub-methods. This study’s results can be used as fundamental sources for improving existing methods and developing new methods of measuring safety climate in the construction industry.
