This study aims to discuss the effect of carbon nanotubes (CNTs) on the mechanical properties of acrylonitrile–butadiene–styrene (ABS) composites fabricated by additive manufacturing (AM). Insight into the energy-dissipation mechanisms introduced and/or enhanced by the addition of CNTs is presented in this study.

ABS/CNT filaments were fabricated with different concentrations of CNTs. Using a fused deposition modeling approach, unidirectional specimens were printed using a MakerBot Replicator 2X (MakerBot Industries, Brooklyn, NY, USA). Specimens were tested under static and dynamic conditions, with the loading coinciding with the printing direction, to determine elastic modulus, strength and viscoelastic properties.

A CNT reinforcing effect is evident in a 37 per cent increase in elastic modulus. Likewise, the strength of the composite increases by up to 30 per cent with an increase in weight fraction of CNTs. At low dynamic strain amplitudes (0.05 per cent), a correlation between dissipated strain energy of the butadiene phase and strength of the composite is found such that less dissipation, from constraint of the butadiene particles by the CNTs, leads to higher strength of the composite. At higher dynamic strains, the presence of a high concentration of CNT leads to increased energy dissipation, with a maximum measured value of 24 per cent higher loss factor compared to baseline specimens. Because the trend of the composite behavior is similar (with a higher absolute value) to that of neat ABS, this study’s results indicate that well-established polymer/CNT dissipation mechanisms (such as stick-slip) are not significant, but that the CNTs amplify the dissipation of the ABS matrix by formation of crazes through stress concentrations.

This study provides knowledge of the dissipation behavior in additively manufactured ABS/CNT composites and provides insight into the expansion to new printable materials for dynamics applications.

Many social accounting researchers refer to environmental pressure groups as being a major influence on companies′ decisions to disclose social information. Such a claim is, however, to date unsubstantiated. Virtually no empirical evidence has been produced which confirms or refutes this proposition. Similarly there is no literature on pressure groups′ interest in, or reaction to, corporate social disclosure (CSD). Provides the first, albeit exploratory, investigation of such pressure groups and their potential influence on the production of CSD. Results show that pressure groups are users of CSD and do attempt to influence companies′ disclosure practices. The environmental movement considers current CSD to be insufficient and low in credibility. The preferred corporate social report (for pressure groups) would include narratives and quantified terms, would be in the annual report and would be prepared by, certified by, and/or held by a body external to the company.

The Dodd‐Frank Act of 2010 is the keystone policy response directed at reforming US financial system activities and oversight in the wake of the 2007‐2009 financial crisis. The USA also has financial system reform policy commitments in the international arena, including in particular by virtue of its membership in the G20. The purpose of this paper is to consider US policy initiatives related to a core dimension of financial system reform: risks posed by systemically important financial institutions (“SIFIs”).

The paper provides a deta‘iled comparison of SIFI policy initiatives and timetables under both the Dodd‐Frank Act and the G20 agenda, as reflected in the ongoing work plan of the Financial Stability Board (FSB), and poses the question “Are US domestic and international financial system reform commitments in sync?”

The study finds that, fundamentally, the answer is “yes.” However, the comparison yields two caveats with potential policy implications. First, the two agendas differ in their relative emphasis on the coverage of both banks and nonbanks. The G20/FSB focus, at least over the near‐term, is bank‐centric compared with the Dodd‐Frank Act, which consistently addresses both bank and nonbank financial firms. Second, implementation of Dodd‐Frank Act provisions is subject to long‐established US law mandating that there be sufficient opportunity for public input into the rulemaking process, whereas the G20/FSB process has been less systematic and transparent on public consultation and feedback.

These observations may be relevant to the current debate over the speed and scope of Dodd‐Frank Act implementation measures, and to the discussion about the future international competitiveness of US banks and nonbank financial firms.

This study is the first to present a detailed, comprehensive comparison of financial system reform initiatives and provisions in the Dodd‐Frank Act and the G20 agenda.

This paper aims to discuss the work of Frank and Lillian Gilbreth and how it is still a fundamental part of business in the twenty‐first century. It is also proposed that the system developed by the Gilbreths could be added as a supplement, or even considered as a replacement to certain modern process management systems.

A qualitative methodology is used and the Gilbreths' system as described in their original works are compared and contrasted with modern process management systems appearing in contemporary literature.

It is found that most modern process management systems are based on the work of the Gilbreths and other seminal thinkers. However, it is suggested that by paying more attention to the human element, the Gilbreths might have developed a more comprehensive system in comparison with current ones.

This paper attempts to reemphasize the role and importance of Frank and Lillian's work as foundational to modern process management systems and to suggest that more attention needs to be given to the human interface in such systems.

By distorting the peer review process, predatory journals lure researchers and collect article processing charges (APCs) to earn income, thereby threatening clinical decisions. This study aims to identifying the characteristics of predatory publishing in the dermatology literature.

The authors used Kscien's list to detect dermatology-related predatory journals. Bibliometric parameters were analyzed at the level of journals, publishers, documents and authors.

Sixty-one potential predatory dermatology publishers published 4,164 articles in 57 journals from 2000 to 2020, with most publishers claiming to be located in the United States. Most journals were 1–5 years old. Six journals were indexed in PubMed, two in Scopus and 43 in Google Scholar (GS). The average APC was 1,049 USD. Skin, patient, cutaneous, psoriasis, dermatitis and acne were the most frequently used keywords in the article's title. A total of 1,146 articles in GS received 4,725 citations. More than half of the journals had <10 citations. Also, 318 articles in Web of Science were contaminated by the most cited articles and 4.49% of the articles had reported their funding source. The average number of authors per article was 3.7. India, the United States and Japan had the most articles from 119 involved countries. Asia, Europe and North America had the most contributed authors; 5.2% of articles were written through international collaboration. A majority of authors were from high- and low-middle-income countries. Women contributed 43.57% and 39.66% as the first and corresponding authors, respectively.

The study had limitations, including heavy reliance on Kscien's list, potential for human error in manual data extraction and nonseparation of types of articles. Journals that only published dermatology articles were reviewed, so those occasionally publishing dermatology articles were missed. Predatory journals covering multiple subjects (Petrisor, 2016) may have resulted in overlooking some dermatology papers. This study did not claim to have covered all articles in predatory dermatology journals (PDJs) but evaluated many of them. The authors accept the claim that Kscien's list may have made a mistake in including journals.

The wide dispersion of authors involved in PDJs highlights the need to increase awareness among these authors.

The purpose of this paper is to describe recent amendments to Rule 144 of the Securities Act of 1933 concerning holding periods and resale of privately placed securities.

The paper describes key changes with respect to shortened holding periods, elimination of most requirements for non‐affiliates, and relaxation of requirements for sale of debt securities.

The paper finds that the SEC has adopted significant amendments to Rule 144 that will increase the liquidity of privately placed securities and ease the burden on issuers caused by having to grant burdensome registration rights. The amendments shorten the holding periods before affiliates and non‐affiliates may sell restricted securities and otherwise loosen restrictions on the public resale of equity and debt securities acquired in private placements.

The paper is a useful guide to rule changes written by experienced securities lawyers.

Sustainability is a major challenge for India’s (Bharat’s) coal mining industry. The government has prioritized sustainable growth in the coal mining industry. It is putting forth multifaceted economic, environmental and social efforts to accomplish the Sustainable Development Goals (SDGs). This research aims to identify the factors for sustainable improvements in coal mining operations. Secondly, this study examines the intensity of causal relations among the factors. Thirdly, this study examines whether causal relations exist among the factors to be considered for sustainable improvement in coal mining operations. Lastly, the study aims to understand how the factors ensure sustainable improvement in coal mining operations.

An integrated three-phase methodology was applied to identify the critical factors related to coal mining and explore the contextual relationships among the identified factors. Fifteen critical factors were selected based on the Delphi technique. Subsequently, the fifteen factors were analyzed to determine the contextual and causal relationships using the total interpretive structural modelling (TISM) and DEMATEL methods.

The study identified “Extraction of Coal and Overburden” as the leading factor for sustainable improvement in coal mining operations, because it directly or indirectly influences the overall mining operation, environmental impact and resource utilization. Hence, strict control measures are necessary in “Extraction of Coal and Overburden” to ensure sustainable coal mining. Conversely, “Health Impact” is the lagging factor as it has very low or no impact on the system. Therefore, it requires fewer control mechanisms. Nevertheless, control measures for the remaining factors must be decided on a priority basis.

The proposed structural model can serve as a framework for enhancing sustainability in India’s (Bharat’s) coal mining operations. This framework can also be applied to other developing nations with similar sustainability concerns, providing valuable guidance for sustainable operations.

The current study highlights the significance of logical links and dependencies between several parameters essential to coal mining sustainability. Furthermore, it leads to the development of a well-defined control sequence that identifies the causal linkages between numerous components needed to achieve real progress towards sustainability.

Rawls, most visibly in A Theory of Justice, made numerous references to various topics in economics, and footnoted a significant number of economists. This paper will argue that Rawls made use of the ideal theory of markets as a reference point and as an analytical tool. In their ideal form, markets represent attributes Rawls intended to describe his system, and in their real-world guise embody certain sorts of striving – for instance, after power – that were central to Rawls’s justification of the original position. Markets also serve in Theory as a benchmark against which political forms can be criticized. Additionally, markets in Theory are approved of as allocative and wealth-producing mechanisms, but criticized for their final distributional results. The paper suggests that these assessments in Rawls likely originate in early essays by economist Frank Knight. Knight was, according to Pogge, the probable source for an early version of Rawls’s original position, and is footnoted in key spots in Theory. But the similarities between Knight’s reasoning and Rawls’s appear more significant still. Using Rawls’s extensively annotated copy of Knight’s Ethics of Competition, that supposition is explored.
