Abstract
Purpose
The article aims to provide an accurate and efficient numerical algorithm for viscous flows in power-law fluids under various thermal boundary and partial slip conditions.
Design/methodology/approach
We are conducting a numerical investigation using the Taylor–Galerkin/pressure correction finite element method, which builds upon the work of previous researchers. Here, attention is therefore given to the interplay of various thermal boundary and stick-slip conditions and their impact on non-isothermal inelastic fluid.
Findings
The results demonstrate the influence of the Prandtl, Brinkman and Reynolds numbers on the flow’s thermal and hydrodynamic behavior, concentrating on the impact of slip at the wall. Furthermore, we have presented the effects of these dimensionless parameters on the detailed local and average Nusselt numbers, illustrated the high accuracy we obtained for numerical convergence, and compared our results with those of previous papers, observing excellent agreement.
Practical implications
We have successfully tested the code under the presented industrial conditions. Future research directions on this topic aim for efficient and robust solvers for non-Newtonian thermal rheological models; this algorithm can be used for that purpose.
Originality/value
This algorithm has never been used for numerical analysis of such a problem previously.

Abstract
Research methodology
This case is based on secondary information and data about the Goldman Sachs One Million Black Women initiative and youth entrepreneurship programs from press releases, news articles and websites. The protagonist has been disguised. This case has been classroom-tested in a core MBA course in both face-to-face and online delivery methods.
Case overview/synopsis
In March 2021, Goldman Sachs launched its One Million Black Women initiative which expanded its inclusive growth goals to support Black women entrepreneurs who were under-represented and under-resourced. This initiative is one of Goldman Sachs’s sponsored programs that aid existing entrepreneurs. This program would invest $10bn over the next decade to advance racial equity, promote entrepreneurial activity and increase and economic opportunities for these highly motivated and resilient Black women. With the buzz from this initiative, Johnnetta who was a Black female manager at a financial services competitor of Goldman Sachs conceived another approach to groom and grow future generations of women of color entrepreneurs. Her idea was to implement youth entrepreneurship programs in middle schools in states with high populations of students of color. Based on a psychological theory of entrepreneurship approach, these students would learn about entrepreneurship and gain hands-on experience with starting and operating a business. The program was called “Planting 1000 Seeds of Entrepreneurs” to develop a pipeline of savvy, well-prepared future women of color entrepreneurs. Johnnetta’s dilemma was whether to pitch this new youth entrepreneurship program as an employee at her employer as a diversity, equity and inclusion (DEI) initiative or start this program as an entrepreneur of a nonprofit in which she would have sole autonomy to administer this program. This case will enable students to develop ideas into a compelling business pitch while sparking debate about approaches to foster DEI initiatives that will have impactful economic benefits for women of color entrepreneurs.
Complexity academic level
This case is best suited for upper-level undergraduate or graduate students taking business administration courses in management, entrepreneurship, women studies or other courses that cover topics or modules related to DEI initiatives involving women in business.

Abstract
Purpose
The present paper offers a literature review on the application of institutional theory in the context of small and medium-sized enterprises (SMEs). The study aims to synthesize existing research on how institutional factors, both formal and informal, shape the strategic behaviors of SMEs through the lens of new institutionalism and its three strands – rational-action neoinstitutionalism (RAN), social-constructionist neoinstitutionalism (SCN) and mediated-conflict neoinstitutionalism (MCN). It also identifies critical gaps and proposes avenues for future research.
Design/methodology/approach
Employing the B-SLR’s multi-method framework, this study integrates bibliometric analysis and a systematic literature review. The analysis examines 202 articles, categorizing them into four key research clusters related to the application of institutional theory to SMEs.
Findings
The literature on SMEs and institutional theory is framed around the following clusters: (1) institutional theory and innovation in SMEs, (2) institutional theory and the environmental sustainability of SMEs, (3) institutional theory and the internationalization of SMEs and (4) institutional theory and SME strategies in emerging markets.
Originality/value
This study represents the first literature review applying institutional theory to SMEs, offering a framework for understanding how institutional factors influence SME strategic decisions. The paper also identifies research gaps, proposing directions for future studies within each of the four clusters and contributes to bridging the fragmented research on SMEs and institutional theory.

The aim of this study is to investigate the effects of the laser cladding process on the microstructure, hardness and corrosion resistance properties of high-entropy alloys (HEA).
Abstract
Purpose
The aim of this study is to investigate the effects of the laser cladding process on the microstructure, hardness and corrosion resistance properties of high-entropy alloys (HEA).
Design/methodology/approach
Laser cladding technology was used, using AlCoCrFeNiCu HEA powder as the cladding material. HEA coatings were prepared on the surface of 45 steel using a coaxial powder feeding method. The microstructure, phase composition, hardness and corrosion resistance properties of the HEA cladding layer were analyzed using optical microscopy (OM), X-ray diffractometer, digital microhardness tester and electrochemical workstation.
Findings
Laser power affects the coating surface; lower power reveals more visible unmelted powder particles. Higher power results in increased melt width and height, a brighter, smoother surface. Phase structure remains consistent, but the coating hardness is significantly higher than the substrate. The hardness of the melted zone in the substrate peaks at approximately 890.5 HV. The cladding zone hardness is about 60 HV higher than the substrate zone. Electrochemical corrosion parameters of the cladding show that, compared to the substrate, Ecor shifts positively by 113 mV, Icor decreases by one order of magnitude and Rp increases by one order of magnitude. These results indicate that the cladding has superior corrosion resistance to the substrate. The bonding strength between the coating and the substrate is greater than 93.6 MPa.
Originality/value
First, based on preliminary pilot experiments, nine sets of single-factor experiments were designed. Through these experiments, a specimen with relatively favorable cross-sectional morphology was observed. This specimen was then subjected to coating research, revealing that its microstructure and properties had significantly improved compared to the substrate. This enhancement holds remarkable significance for prolonging the service life of components.
