Numerical investigation of nanofluid buoyant flow behavior and heat transfer characteristics in annular-shaped enclosure with internal baffle
Authors: Reddy N. Keerthi , Yoon Aejung , Mani Sankar , Swamy H.A. Kumara 
Published: October 2023

PurposeNatural convection in finite enclosures is a common phenomenon in various thermal applications. To provide the thermal design guidelines, this study aims to numerically explore the potential of using internal baffles and nanofluids to either enhance or suppress heat transport in a vertical annulus. Furthermore, the annular-shaped enclosure is filled with aqueous-silver nanofluid and the effects of five distinct nanoparticle shapes are examined. In addition, the influence of baffle design parameters, including baffle position, thickness and length, is thoroughly analyzed.Design/methodology/approachThe finite difference method is used in conjunction with the alternating direction implicit and successive line over relaxation techniques to solve nonlinear and coupled partial differential equations. The single phase model is used for nanofluid which is considered as a homogeneous fluid with improved thermal properties. The independence tests are carried out for assessing the sufficiency of grid size and time step for obtaining results accurately.FindingsThe baffle dimension parameters and nanoparticle shape exhibit significant impact on the convective flow and heat transfer characteristics, leading to the following results: sphere- and blade-shaped nanoparticles demonstrate around 30% enhancement in the heat transport capability compared with platelet-shaped nanoparticles, which exhibit the least. When considering the baffle design parameter, either a decrease in the baffle length and thickness or an increase in baffle height leads to an improvement in heat transport rate. Consequently, a threefold increase in baffle height yields a 40% improvement in thermal performance.Originality/valueUnderstanding the impact of nanoparticle shapes and baffle design parameters on flow and thermal behavior will enable engineers to provide valuable insight on thermal management and overall system efficiency. Therefore, the current work focuses on exploring buoyant nanofluid flow and thermal mechanism in a baffled annular-shaped enclosure. Specifically, an internal baffle that exhibits conductive heat transfer through it is considered, and the impact of baffle dimensions (thickness, length and position) on the fluid flow behavior and thermal characteristics is investigated. In addition, the current study also addresses the influence of five distinct nanoparticle shapes (e.g. spherical, cylindrical, platelet, blade and brick) on the flow and thermal behavior in the baffled annular geometry. In addition to deepening the understanding of nanofluid behavior in a baffled vertical annulus, the current study contributes to the ongoing advancements in thermal applications by providing certain guidelines to design application-specific enclosures.
Climate change energy futures in business, industry and mining in Saskatchewan, Canada
Authors: Hurlbert Margot , Das Tanushree , Vitto Charisse 
Published: October 2023

Purpose
This study aims to report business preferences for achieving net-zero power production emissions in Saskatchewan, Canada as well as business perceptions of the most preferable power production sources, barriers to change and suggestions for improvement. Mixed methods included focus groups and a survey with experimental design. This research demonstrates that this method of advancing academic and business knowledge systems can engender a paradigmatic shift to decarbonization.

Design/methodology/approach
The study is a mixed-methods study using five focus groups and a survey which included a 15-min information video providing more information on power production sources (small modular reactors and biomass). Participants requested more information on these topics in the initial three focus groups.

Findings
There is a significant gap in Canadian Government targets for net-zero emissions by 2050 and businesses’ plans. Communications, knowledge and capacity gaps identified include lack of regulatory requirements, institutional barriers (including a capacity charge in the event a business chooses to self-generate with a cleaner source) and multi-level governance dissonance. More cooperation between provincial governments and the federal government was identified by participants as a requirement for achieving targets. Providing information to survey respondents increased support for clean and renewable sources, but gender and knowledge are still important characteristics contributing to support for different power production sources. Scientists and teachers were the most trusted sources of information. Power generated from small modular nuclear reactors was identified as the primary future source of power production followed by solar, wind and natural gas. Research results also confirmed the high level of support for hydropower generated in Saskatchewan versus import from Manitoba based on high values of energy solidarity and security within the province.

Originality/value
This study is original, as it concerns upstream system power production portfolios and not failed projects; the mixed-method research design including a focus group and an experimental survey is novel. This research partially addresses a gap in knowledge surrounding which knowledge systems advance paradigmatic shifts and how and whether involving business people in upstream power production decisions can inform decarbonization.
Does work-family conflict mediate the effect of psychological resilience on tour guides’ happiness?
Authors: Dönmez Filiz Gümüş , Gürlek Mert , Karatepe Osman M. 
Published: October 2023

Purpose
This paper aims to explore work interfering with family (WIF) and family interfering with work (FIW) as the mediators linking psychological resilience to happiness.

Design/methodology/approach
Data gathered from tour guides in Türkiye were used to test the aforesaid associations. In this paper, partial least squares structural equation modeling was performed to gauge the direct links and mediating impacts of WIF and FIW simultaneously in the link between psychological resilience and happiness.

Findings
Psychological resilience exerts a dual influence on WIF and FIW. Simply put, psychologically resilient tour guides balance their work demands with those of the family or vice versa and exhibit low levels of WIF and FIW. As hypothesized, WIF and FIW are the two mediating mechanisms relating psychological resilience to happiness.

Practical implications
It is important to create a family-supportive atmosphere where tour guides can avail themselves of family-friendly practices (i.e. family leave, flexible work schedules, breaks to be spent with family members after long tours and convenient working hours). Psychologically resilient tour guides, with the abovementioned practices, would experience alleviated conflicts between work and family roles and would therefore have heightened happiness.

Originality/value
Although the extant literature has presented plenty of empirical studies about the predictors and outcomes of WIF and FIW, evidence about the links of personal resources as third variables to WIF and FIW simultaneously is still scanty. In addition, there is no evidence linking personal resources such as psychological resilience to nonwork outcomes such as happiness through the mediating roles of WIF and FIW. This paper fills in these voids by gauging the links given above using data collected from tour guides, a population that has been subjected to limited inquiry in the WIF and FIW literature.
Oil price uncertainty and corporate inventory investment
Authors: Singh Amanjot 
Published: October 2023

PurposeThis study examines the relationship between oil price uncertainty (OPU) and corporate inventory investments using a sample of 6,072 USA manufacturing firms from 1992 to 2019.Design/methodology/approachThe author's study employs a panel dataset to examine the relationship between OPU and corporate inventory investments. The author uses several alternative specifications such as fixed effects models, an instrumental variable analysis, an impact threshold for confounding variable (ITCV) analysis, alternative measures, additional control variables and the percent bias analysis to account for endogeneity issues.FindingsCorporate inventory investments decrease in response to high OPU. This decrease in inventory investments happens regardless of firms' expected stockout costs, information environment and reliance on external financing. As a potential mechanism, an uncertainty-induced increase in cash holdings contributes to this reduction in inventory investments. Also, the effect of OPU is non-linear and asymmetric. In response to the volatility of positive (negative) oil price changes, inventory investments decrease (increase) up to a certain point and increase (decrease) after that. Further, uncertainty-induced adjustments in inventory investments positively influence the operating performance of firms.Originality/valueThe author's study adds to the growing literature that examines the impact of OPU on corporate outcomes. Inventory investments directly affect business operations and could better reflect firms' responses to an uncertain environment.
Do the certainty tone and seniority of physicians matter in patients' information adoption in online health communities?
Authors: Jin Jiahua , Chen Qin , Yan Xiangbin 
Published: October 2023

PurposeGiven the popularity of online health communities (OHCs) and medical question-and-answer (Q&A) services, it is increasingly important to understand what constitutes useful answers and user-adopted standards in healthcare domain. However, few studies provide insights into how health information characteristics, provider characteristics and recipient characteristics jointly influence user information adoption decisions. To fill this research gap, this study examines the combined effects of physicians' certainty tone as information characteristics, seniority as provider characteristics and disease severity as recipient characteristics on patients' health information adoption.Design/methodology/approachDrawing on dual-process theory and information adoption model, an extended information adoption model is established in this study to examine the effect of attitude certainty on patients' health information adoption, and the moderating effects of online seniority and offline seniority, as well as patient motivation level—disease severity. Utilizing logit regression models, the authors empirically tested the hypotheses based on 4,224 Q&A records from a popular Chinese OHC.FindingsThe results show that (1) attitude certainty has a significant positive impact on patients' health information adoption, (2) the relationship between attitude certainty and information adoption is negatively moderated by physicians' online seniority, but is positively moderated by offline seniority; (3) there is a negative three-way interaction effect of attitude certainty, online seniority and disease severity on patients' health information adoption.Originality/valueThis study extends the information adoption model to examine the two-way interaction between argument quality and source reliability, as well as the three-way interaction with user motivation level, especially for health information adoption in the healthcare field. These findings also provide direct practical applications for knowledge contributors and OHCs.

Authors: Zhong Huijie , Zhang Xinran , Chan Kam C. , Yan Chao 
Published: October 2023

PurposeRobots are widely used in industrial manufacturing and service industries around the world. However, most of the previous studies on industrial robots use data at the national or industry level in the context of developed countries. This study examines the impact of imported industrial robots on firm innovation at the firm level in China.Design/methodology/approachDrawing on a large dataset of more than three million records in China, including non-publicly traded small and medium firms, the authors adopt a difference-in-differences method to investigate the impact and channels of industrial robots on firm innovation.FindingsThe authors find that the application of industrial robots increases firm innovation. Two possible channels are identified through which robots promote innovation: alleviation of financial constraints and the improvement of human capital. Further analysis shows that the effect of robots on innovation is more pronounced for firms that are highly dependent on external financing, belong to high-tech industries, import high-end robots, have insufficient supply of skilled labor and private firms (non-SOEs). The authors also find that industrial robots increase the firms' innovation quality and the marginal contribution of innovation to firms' total factor productivity.Originality/valueThis study provides big data evidence of the unintended positive consequences of industrial robots on firm innovation. The results are helpful to clarify the controversy of industrial robots. It also has important implications for government industrial policy making, firm innovation and human resource management.

Catering to the experts: food marketing and health professionals in the early 20th century
Authors: Greenfield Rachel 
Published: October 2023

Purpose
This paper aims to examine the marketing strategies designed by three innovative early 1900s food companies. It traces the coordination of these businesses’ research funding, advertising, direct mail and promotional tactics to show how they intersected and impacted consumers and health professionals in the period when scientists were first able to quantify the relationship between good health and food. The paper analyzes internal company documents, advertisements and marketing materials from Knox Gelatine, Borden and Sunkist.

Design/methodology/approach
Research for this paper benefited from the author’s unlimited access to the private documents of the Knox Gelatine Company and its executives. These documents were analyzed chronologically and thematically. They chronicled the company’s attempts to influence the medical world and the ways it cultivated home economists. The paper also used publicly available digitized documents from Sunkist and Borden. The paper would benefit from further detailed analysis of these documents to parse Knox’s targeting by race and ethnicity.

Findings
In the 1920s, Knox, Borden and Sunkist developed a marketing strategy which leveraged a new class of experts – the hundreds of thousands of medical professionals, home economists, teachers and government agents who advised American women. By distributing specific laboratory research on the nutritional benefits of their products to this emerging class of health professionals and the consumers who trusted them, these companies developed relationships with opinion leaders designed specifically to influence product sales.

Research limitations/implications
This research benefited from access to the private documents of Knox Gelatine Company which divulge the company’s attempts to influence the medical world and cultivate home economists. The paper would benefit from further analysis of these documents to parse the company’s targeting by race and ethnicity as well as a deeper comparison to companies that tried to work with health professionals unsuccessfully and companies that adopted this tactic in the household products or tobacco area. Opportunities also exist to do a fuller analysis of variations in food marketing by rural versus urban as well as race.

Originality/value
By reconstructing the sequencing and content of these three companies’ 1920s marketing strategies, this research uncovers a form of early 20th century food marketing directed at health and science professionals which has been neglected in advertising histories.
Investigation on effect of carbon equivalent and inoculation on the solidification and shrinkage tendency of ductile cast iron using thermal analysis
Authors: Sangame Bahubali Babanrao , Reddy Y. Prasannatha 
Published: October 2023

PurposeThe foundry industry incurs additional costs as a result of defective castings. Shrinkage defects are a frequent problem in ductile iron castings. It is still essential to understand how shrinkage porosity varies in size when the ductile iron composition changes. This information can be used to produce high-quality cast parts and determine the best processing conditions. The objective of this research paper is to examine the effect of carbon equivalent and inoculation on the morphology of the shrinkage defect using thermal analysis.Design/methodology/approachThis study focuses on certain thermal analysis parameters, such as the angle of the first derivative curve at the solidus temperature, recalescence and its relationships to graphite nucleation and shrinkage tendency. The results of thermal analysis in terms of the cooling curve and its derivative parameters, and thorough characterizations of the shrinkage observed in cup castings produced with various melt compositions and inoculation are presented in the current study.FindingsThe proportion of caved surfaces and macro shrinkage porosity defects has been reduced as the carbon equivalent of melt increases from hypoeutectic to a hypereutectic composition. The composition that is slightly hypereutectic has the lowest shrinkage propensity. Although inoculation reduces shrinkage, the importance of this parameter differs depending on the carbon equivalent.Originality/valueThe percentage of macro shrinkage porosity and the angle that the cooling rate curve forms are strongly correlated. It is found that the macro shrinkage size decreases as the angle of the first derivative curve at the solidus temperature is reduced. Further, lower macroporosity is produced by a metal that has a higher nodule count in association with a greater cooling rate toward the end of the solidification process.
