Published: July 2022

PurposeThe purpose of this study is to understand the differences in motivations, advantages, disadvantages and time of multiple-major awareness among students who pursue multiple majors based on a set of defined characteristics. The student characteristics of interest included race, gender, financial aid status, class standing, transfer status, first-generation status and the number of majors.Design/methodology/approachThe authors administered a survey instrument to a random sample of multiple-major undergraduate students to gauge the prevalence of motivations, advantages, disadvantages and time of multiple-major awareness themes developed during individual interviews.FindingsStatistical analysis revealed significant differences among multiple-major students based on characteristics of interest. Results discussed at length include transfer students deriving higher levels of motivation from degree practicality than nontransfer students and students who receive financial aid indicating multiple passions as a primary motivation more frequently than students not receiving financial aid. Similar differences between male and female students are uncovered relating to perceived advantages of diverse interactions and experiences and increased balance, as well as perceived disadvantages of time commitment and ability to grow professionally. Finally, first-generation students learned about multiple majoring later than non-first-generation students.Originality/valueThis study builds on previous research regarding multiple-major students, an understudied yet important population in higher education. Additionally, it delves deeper by exploring differences in this population by student characteristics.

Published: July 2022

Purpose
The COVID-19 pandemic has impacted 222 countries across the globe, with millions of people losing their lives. The threat from the virus may be assessed from the fact that most countries across the world have been forced to order partial or complete shutdown of their economies for a period of time to contain the spread of the virus. The fallout of this action manifested in loss of livelihood, migration of the labor force and severe impact on mental health due to the long duration of confinement to homes or residences.

Design/methodology/approach
The current study identifies the focus areas of the research conducted on the COVID-19 pandemic. Abstracts of papers on the subject were collated from the SCOPUS database for the period December 2019 to June 2020. The collected sample data (after preprocessing) was analyzed using Topic Modeling with Latent Dirichlet Allocation.

Findings
Based on the research papers published within the mentioned timeframe, the study identifies the 10 most prominent topics that formed the area of interest for the COVID-19 pandemic research.

Originality/value
While similar studies exist, no other work has used topic modeling to comprehensively analyze the COVID-19 literature by considering diverse fields and domains.

Authors: Singh Ashish Kumar , Sharma Prayas 
Published: July 2022

Purpose
Amid the COVID-19 contamination, people are bound to use contactless FinTech payment services. Because of restrictions on physical movement and avoidance of touching physical money, people willingly choose mobile payment, resulting in enormous growth in FinTech payment service industries. Because of this, this study aims to examine the effect of factors affecting Gen X and Millennials users to use FinTech payment services.

Design/methodology/approach
The authors used 328 responses collected through convenience sampling of Indian users aged between 26 and 57 years in the Delhi-NCR region who are users of FinTech payment services.

Findings
The authors’ findings verified that in India, perceived COVID-19 risk, perceived severity for COVID, individual mobility, subjective norms, perceived ease of use and perceived usefulness have statistically significant impacts on FinTech payment services during the COVID-19 pandemic. Structural equation modelling was used to study the proposed research model. Overall, the model predicted 76.9 % of the variation in intention to use FinTech payment services by the abovesaid variables by Indian users during a pandemic.

Practical implications
This study will provide valuable insight to all FinTech service providers and stakeholders in planning and designing the concerned policy. It will be able to draw the attention of users more.

Originality/value
This research added a valuable theory to the existing technology adoption model (TAM) theory. It demonstrated the utility of the above variables in adopting and using FinTech payment services, which will help service providers to develop future strategies because of the COVID-19 pandemic.

Authors: Mohd Arshad Khairul , Mat Noor Muhamad , Manaf Asrulnizam Abd , H. Kawarada , S. Falina , M. Syamsul 
Published: July 2022

Purpose
Vertical-cavity surface-emitting laser (VCSEL) is a high-performance semiconductor device made of unique epitaxial layers grown on n-type GaAs or InP substrates. The VCSEL’s thermal resistance, Rth, is an essential metric that reflects its thermal properties and dependability. The purpose of this paper is to develop packaging for 1 mm2 VCSEL chips made of a variety of materials, such as ceramic, lead frame and printed circuit board (PCB)-based packaging, as well as provide an idea or design that can withstand and perform well in terms of Rth and heat dissipation during operation. SolidWorks 2017 and AutoCAD Mechanical 2017 software were used to publish all thoughts and ideas, including the size dimensions (x, y and z) and material choices for each package.

Design/methodology/approach
Following the modelling and material selection, the next step is to use the Ansys Mechanical Structural FEA Analysis software to simulate all packaging for Rth and determine which packaging produced the best result, therefore, determining the heat dissipation for each packing. All parameters were used based on the standard cleanroom requirement for the industrial manufacturing backend process, where the cleanroom classification is 10,000 particles (ISO 7). The results demonstrated that the ceramic and lead frame provided good Rth values of 7.3 and 7.0 K/W, respectively, when compared to the PCB, which provided more than 80 K/W; thus, the heat dissipation for PCB packaging also increased.

Findings
As a result of the research, it was determined that ceramic and lead frame packaging are appropriate and capable of delivering good Rth and heat dissipation values when compared to PCB. In comparison to PCB, which requires numerous modifications, such as adding via holes and a thermal bar in an attempt to lower the Rth value, neither packaging requires improvement. Ceramic was chosen for development based on Rth's highest performance, with the actual device consisting of a lead frame and PCB. The Zth measurement test was carried out on a ceramic package, and the Rth result was comparable to the simulation result of 7.6 K/W, indicating that simulation was already proved for research and development.

Originality/value
The purpose of this study is to determine which proposed packaging design would give the highest Rth performance of a 1 mm2 chip as well as the best heat dissipation. In comparison to other studies, VCSEL packaging used the header and window cap as package components with a wavelength of 850 nm, and other VCSEL packaging developments used the sub mount on ceramic package with an output power ranging from 500 mW to 2 W, whereas this study used a huge wavelength and an output power of 4 W.

AbstractIn recent years, circulating cell‐free DNA (cfDNA) has received a great attention as a biomarker for various cancers. Many reports have shown that serum cfDNA levels are elevated in cancer patients and their levels correlate with prognosis and disease activity. The aim of this study was to measure serum cfDNA levels in patients with cutaneous T‐cell lymphoma (CTCL) and to evaluate their correlations with hematological and clinical findings. Serum cfDNA levels in CTCL patients were significantly higher than those in healthy controls, and their levels gradually increased with the progression of the disease stage. Positive correlations were detected between serum cfDNA levels and those of lactate dehydrogenase, thymus and activation‐regulated chemokine and soluble IL‐2 receptor as well as neutrophil and eosinophil count in peripheral blood and neutrophil‐to‐lymphocyte ratio. Furthermore, CTCL patients with higher serum cfDNA levels exhibited a significantly worse prognosis. Taken together, these results suggest the potential of cfDNA as a new biomarker reflecting prognosis and disease activity in CTCL. CfDNA levels may serve as an indicator for considering the intensity and timing of subsequent therapeutic intervention.
The story so far: A systematic review of the dialogic reading literature
Authors: Pillinger Claire , Vardy Emma J. 
Published: July 2022

BackgroundDialogic reading (DR; Whitehurst et al., 1988) is an evidence‐based intervention that promotes children's active participation in shared reading (Towson, 2016; Urbani, 2020; WWC, 2007, 2010). Since the development of DR, there has been a proliferation of studies evaluating the conditions and populations with which it is effective. However, to date, there has not been a systematic review of the literature focusing specifically on the impact of DR on the literacy and non‐literacy skills of children under 10 years old. As DR research evolves, it is important that a review of the existing literature is undertaken to capture these advances and guide future research.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses protocol, the aim of this review is to systematically explore, synthesise and critically evaluate the extant literature. A systematic search of electronic databases identified 46 relevant studies, and the overall methodological quality of the studies was assessed using the MMAT.ResultsFindings are organised according to sample and population, country of origin and setting, programme duration, language and literacy outcomes, social‐emotional and other cognitive outcomes, impact and effect sizes to provide overview and insight into where and with whom DR is most effective.ConclusionsThe review findings suggest DR can positively impact a wide range of language and literacy skills for children under 5 years. There is some evidence that DR can have positive effects on enjoyment of reading, reading motivation, parental–child attachment, parental confidence and stress. However, the extant research is subject to limitations, and more methodologically robust research is needed to enable thorough assessment of the conditions in which DR is most effective.

Published: July 2022

ABSTRACTMafia firms introduce distortions in the markets in which they operate, increasing the cost of doing business for peer firms. We investigate whether peers respond by increasing their tax avoidance and thus increasing funds available to compete with the Mafia firms. Using a sample of Italian anti‐Mafia police actions that resulted in the removal of Mafia firms and a difference‐in‐differences approach, we find that peers reduce their tax avoidance following these actions. We further show that, following anti‐Mafia police actions, peer firms improve their performance and increase capital investment while enjoying a reduction in the cost of raw materials. Overall, our results highlight the microlevel channels through which Mafia can affect firm outcomes and local economies.
Potential interactions between starch and fruit pomace may impact the expansion ratio of direct expanded extrudates

Published: July 2022

AbstractDue to their dense characteristics, direct‐expanded products fortified with insoluble fiber are generally not well accepted. Understanding the interactions between starch and fiber could help to effectively choose and modify ingredients to produce products containing high amounts of fiber. Therefore, this study aims to explain the interplay between two starches (native and waxy corn) and two pomace types (blueberry and cranberry). Blends up to 100% of pomace were extruded using a co‐rotating twin‐screw extruder. Raw material and milled extrudates were analyzed for their pasting and hydration properties. Fourier‐transform infrared (FTIR) and solid‐state nuclear magnetic resonance (NMR) spectroscopy were conducted to observe molecular changes. The expansion ratio (ER) significantly decreased as pomace was added and ranged from 3.85 for pure waxy corn starch to approximately 1 for blends that contained 80% pomace. Distinctions between the blends were observed. Particularly, at 20% of pomace inclusion, native corn starch with cranberry pomace showed a significantly higher ER. Different behaviors were also detected during the physicochemical analyses. A nonlinear trend between pomace level and water solubility as well as absorption was observed for native corn starch blends, suggesting that molecular interactions between the biopolymers occur. FTIR and NMR results give no evidence for new covalent bonds; hence, the most likely interactions occurring are hydrogen bonds. In addition to the dilution effect of pomace addition, the enhancement or weakening of such interactions between starch molecules by pomace compounds may reduce the ER.

AbstractBurkholderia have potential as biocontrol agents because they encode diverse biosynthetic gene clusters (BGCs) for a range of antimicrobial metabolites. Given the opportunistic pathogenicity associated with Burkholderia species, heterologous BGC expression within non‐pathogenic hosts is a strategy to construct safe biocontrol strains. We constructed a yeast‐adapted Burkholderia‐Escherichia shuttle vector (pMLBAD_yeast) with a yeast replication origin 2 μ and URA3 selection marker and optimised it for cloning BGCs using the in vivo recombination ability of Saccharomyces cerevisiae. Two Burkholderia polyyne BGCs, cepacin (13 kb) and caryoynencin (11 kb), were PCR‐amplified as three overlapping fragments, cloned downstream of the pBAD arabinose promoter in pMLBAD_yeast and mobilised into Burkholderia and Paraburkholderia heterologous hosts. Paraburkholderia phytofirmans carrying the heterologous polyyne constructs displayed in vitro bioactivity against a variety of fungal and bacterial plant pathogens similar to the native polyyne producers. Thirteen Paraburkholderia strains with preferential growth at 30°C compared with 37°C were also identified, and four of these were amenable to genetic manipulation and heterologous expression of the caryoynencin construct. The cloning and successful heterologous expression of Burkholderia biosynthetic gene clusters within Paraburkholderia with restricted growth at 37°C opens avenues for engineering non‐pathogenic biocontrol strains.

Published: July 2022

AbstractCordyceps militaris is a popular edible fungus with important economic value worldwide. In this study, an efficient CRISPR/Cas9 genome‐editing system based on an autonomously replicating plasmid with an AMA1 sequence was constructed. Further, a precisely targeted gene deletion via homology‐directed repair was effectively introduced in C. militaris. Gene editing was successful, with efficiencies of 55.1% and 89% for Cmwc‐1 and Cmvvd, respectively. Precisely targeted gene deletion was achieved at an efficiency of 73.9% by a single guide RNA supplementation with donor DNAs. Double genes, Cmwc‐1 and Cmvvd, were edited simultaneously with an efficiency of 10%. Plasmid loss was observed under non‐selective culture conditions, which could permit recycling of the selectable marker and avoid the adverse effects of the CRISPR/Cas9 system on the fungus, which is beneficial for the generation of new cultivars. RNA Pol III promoters, endogenous tRNAPro of C. militaris, and chimeric AfU6‐tRNAGly can be used to improve the efficiency. Polyethylene glycol‐mediated protoplast transformation was markedly more efficient than Agrobacterium tumefaciens‐mediated transformation of C. militaris. To our knowledge, this is the first description of genome editing and precisely targeted gene deletion in mushrooms based on AMA1 plasmids. Our findings will enable the modification of multiple genes in both functional genomics research and strain breeding.

Published: July 2022

AbstractEarly‐stage inclusion body formation is still mysterious. Literature is ambiguous about the existence of rod‐shaped protein aggregates, a potential sponge‐like inclusion body scaffold as well as the number of inclusion bodies per Escherichia coli cell. In this study, we verified the existence of rod‐shaped inclusion bodies, confirmed their porous morphology, the presence of multiple protein aggregates per cell and modelled inclusion body formation as function of the number of generations.
