Effect of aspect ratio on mean flow characteristics of cruciform orifice jet
Authors: S. Rajesh Kumar , Sadrani Nishchay , B.T. Kannan 
Published: December 2023

Purpose
The purpose of this study reports the effects of aspect ratio (AR) on mean flow characteristics of the cruciform orifice jet.

Design/methodology/approach
The aspect ratio is the height-to-width ratio of the lobe of the cruciform shape. The aspect ratios considered are 0.25, 0.5, 0.75, 1, 2, 3 and 4. The turbulent jet flow is issued through an orifice being fitted to the jet tunnel facility. The velocity measurements are recorded with the help of pitot-static tube connected to a digital manometer setup. The Reynolds number calculated using the equivalent diameter 50.46 × 10–3 m and exit velocity 51.23 m/s was 1.75 × 105. Based on the experimental data, the streamline velocity decay plots, the potential core length (PCL), mean velocity profiles and velocity half widths were plotted, and discussions were made based on the measured data. A smoke-based flow visualization was carried out at moderate Reynolds number 5396.

Findings
The PCL remains almost constant for the aspect ratio 0.25:1 and then starts decreasing for the aspect ratio 1:4. The decrease in PCL indicates improved mixing. The off-center peaks are found along the major axis in mean velocity profiles for almost all cruciform jets. More than one axis switching occurs and can be identified by the crossover points. The location of the first crossover point shifts forward, and the second crossover point shows an oscillating trend. The flow visualization exhibits the jet evolution, and the distance up to which the jet maintains the cruciform shape is increased with the aspect ratio.

Research limitations/implications
The experiments are limited to air in air jet under isothermal conditions.

Social implications
The cruciform orifices can be used as fuel injectors and in air-conditioning systems, thereby improving efficiency and energy usage.

Originality/value
The aspect ratio effects on PCL and axis switching are used to explain the mixing characteristics. Flow visualization was also used to support the discussion.

Published: December 2023

Purpose
The purpose of this study was to explore the relationship between entrepreneurial passion for founding firms (EPFF) and persistence in venture start-ups and to examine the mediating role of searching and scanning alertness, association and connection alertness and evaluation and judgment alertness (i.e. entrepreneurial alertness).

Design/methodology/approach
Using a three-way parallel mediation involving searching and scanning alertness, association and connection alertness and evaluation and judgment alertness, on data from 342 serial entrepreneurs from Nigeria, the authors examined the influence of EPFF on persistence in venture start-ups, through a parallel mediation involving searching and scanning alertness, association and connection alertness and evaluation and judgment alertness.

Findings
The authors find that EPFF was not significantly related (positive) to persistence in venture start-ups, but that searching and scanning alertness, association and connection alertness and evaluation and judgment alertness mediated the path through which EPFF impacts persistence in venture start-ups. Thus, entrepreneurial alertness is relevant in explaining the relationship between EPFF and persistence in venture start-ups in Nigeria.

Originality/value
The findings of this study highlight the relevance of EPFF and alertness in explaining persistence in venture start-ups in Nigeria.

Authors: Al-Refaei Abd Al-Aziz Hamed , Ali Hairuddin Mohd , Aldaba Abdulmajid Mohammed , Zumrah Abdul Rahim 
Published: December 2023

Purpose
This study aims to examine the constructs of job satisfaction and organizational commitment (OC) as the determinants of customer-perceived service quality in higher education context. It also explores the role of OC in mediating the dynamics of the relationship.

Design/methodology/approach
It applied the cross-sectional, ex post facto survey method to acquire data from 1,776 respondents at Aden University. Two sets of questionnaires on job satisfaction, OC and perceived service quality were filled out by 296 academic staff and 1,480 students. Data were analyzed using structural equation modeling.

Findings
The results showed that job satisfaction exercised a significant positive effect on OC and students’ perception of service quality (i.e. the quality of lectures delivered in class that shaped their learning experiences). OC also significantly affected students’ perception of service quality and partially mediated the effect of job satisfaction on perceived service quality.

Research limitations/implications
The current research only investigated the outcomes of job satisfaction and did not cover critical antecedents of job satisfaction, such as employee training and development, rewards and benefits and the like. Its outcomes have important implications for managing the link between organizational practices and customers perception of service quality in higher education context.

Practical implications
The results have accentuated the importance of universities’ ensuring and increasing faculty’s job satisfaction and commitment if they seek to enhance students’ perception of service quality. Universities can do so by improving their organizational practices, which are expected to result in faculty well-being and improved working conditions.

Originality/value
The results have contributed new insights into the current understanding of the dynamics between and among job satisfaction, OC and customers’ perceptions of service quality. It has demonstrated how OC is shaped by job satisfaction and can influence the quality of services rendered by employees if they are happy and satisfied with the organization.
The extent of “deceptive” advertising by wine retailers: caveat venditor
Authors: Gokcekus Omer 
Published: December 2023

Purpose
The purpose of this study is to assess the presence of deceptive advertising practices in wine retailers’ e-mails and, if identified, to analyze the extent and content of these deceptive advertisements.

Design/methodology/approach
The study follows an observational research design to examine the accuracy of two claims that were made in 258 marketing e-mails from two major wine retailers in New Jersey, USA: (1) that all wines have 90+ scores; and (2) that these wines are offered at a deeply discounted price.

Findings
The study found that only 3.9% of cases accurately supported both major claims made: the wines having 90+ scores and being offered at a discounted price. Both claims were inaccurate in 64.7% of cases. Nearly half (49.3%) of the advertised wines had concealed critic’s scores below 90 points. Recipients were told they could save 37.2% by purchasing from the advertising retailer, but they could have actually saved 12.7% more by buying the wines elsewhere.

Research limitations/implications
The study’s limitations include the small sample size. Variations between different wine retailers and their advertising practices require further investigation.

Practical implications
Advertised discounts and scores may be inaccurate or incomplete, causing consumer confusion and disappointment, erosion of wine advertisements’ as well as wine retailers’ and wine experts’ credibility.

Social implications
Deceptive advertising can erode consumer trust and lead to unfair practices. Consumers may make purchasing decisions based on misleading information. Deceptive practices create an uneven playing field, giving businesses that engage in them an unfair advantage, hindering market transparency and ethical businesses. Policymakers should develop regulations to protect consumers and ensure fair competition.

Originality/value
An investigation of deceptive advertising practices in the wine industry has not been done before. This exploratory study contributes to consumer awareness and highlights the importance of truthful and transparent marketing practices.

Participants in this study were AI PhD students from Tehran University in 2022–2023. Purposive sampling was used to select the participants; a total of 15 AI PhD students, who were experts in this field, were selected and interviews were conducted.FindingsThe authors considered the opportunities that AI creates for higher education in eight secondary subthemes (for faculty members, for students, in the teaching and learning process, for assessment, the development of educational structures, the development of research structures, the development of management structures and the development of academic culture). Correspondingly, The authors identified and categorized the challenges that AI creates for higher education.Research limitations/implicationsConcerning the intended research, several limitations are significant. First, the statistical population was limited, and only people with characteristics such as being PhD students, studying at Tehran University and being experts in AI could be considered the statistical population. Second, caution should be exercised when generalizing the results due to the limited statistical population (PhD students from Tehran University). Third, the problem of accessing some students due to their participation in research grants, academic immigration, etc.Originality/valueThe innovation of the current research is that the authors identified the opportunities and challenges that AI creates for higher education at different levels. The findings of this study also contribute to the enrichment of existing knowledge in the field regarding the effects of AI on the future of higher education, as researchers need more understanding of AI developments in the future of higher education.
A study on risk sharing of smart city PPP projects based on EW-G1 and TOPSIS-UT: a case study in China
Authors: Zhao Hui , Cheng Xian , Gao Jing , Yu Guikun 
Published: December 2023

PurposeBuilding a smart city is a necessary path to achieve sustainable urban development. Smart city public–private partnership (PPP) project is a necessary measure to build a smart city. Since there are many participants in smart city PPP projects, there are problems such as uneven distribution of risks; therefore, in order to ensure the normal construction and operation of the project, the reasonable sharing of risks among the participants becomes an urgent problem to be solved. In order to make each participant clearly understand the risk sharing of smart city PPP projects, this paper aims to establish a scientific and practical risk sharing model.Design/methodology/approachThis paper uses the literature review method and the Delphi method to construct a risk index system for smart city PPP projects and then calculates the objective and subjective weights of each risk index through the Entropy Weight (EW) and G1 methods, respectively, and uses the combined assignment method to find the comprehensive weights. Considering the nature of the risk sharing problem, this paper constructs a risk sharing model for smart city PPP projects by initially sharing the risks of smart city PPP projects through Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to determine the independently borne risks and the jointly borne risks and then determines the sharing ratio of the jointly borne risks based on utility theory.FindingsFinally, this paper verifies the applicability and feasibility of the risk-sharing model through empirical analysis, using the smart city of Suzhou Industrial Park as a research case. It is hoped that this study can provide a useful reference for the risk sharing of PPP projects in smart cities.Originality/valueIn this paper, the authors calculate the portfolio assignment by EW-G1 and construct a risk-sharing model by TOPSIS-Utility Theory (UT), which is applied for the first time in the study of risk sharing in smart cities.

MCFilter: feature filter based on motion-correlation for LiDAR SLAM
Authors: Sun Han , Tang Song , Qi Xiaozhi , Ma Zhiyuan , Gao Jianxin 
Published: December 2023

Purpose
This study aims to introduce a novel noise filter module designed for LiDAR simultaneous localization and mapping (SLAM) systems. The primary objective is to enhance pose estimation accuracy and improve the overall system performance in outdoor environments.

Design/methodology/approach
Distinct from traditional approaches, MCFilter emphasizes enhancing point cloud data quality at the pixel level. This framework hinges on two primary elements. First, the D-Tracker, a tracking algorithm, is grounded on multiresolution three-dimensional (3D) descriptors and adeptly maintains a balance between precision and efficiency. Second, the R-Filter introduces a pixel-level attribute named motion-correlation, which effectively identifies and removes dynamic points. Furthermore, designed as a modular component, MCFilter ensures seamless integration into existing LiDAR SLAM systems.

Findings
Based on rigorous testing with public data sets and real-world conditions, the MCFilter reported an increase in average accuracy of 12.39% and reduced processing time by 24.18%. These outcomes emphasize the method’s effectiveness in refining the performance of current LiDAR SLAM systems.

Originality/value
In this study, the authors present a novel 3D descriptor tracker designed for consistent feature point matching across successive frames. The authors also propose an innovative attribute to detect and eliminate noise points. Experimental results demonstrate that integrating this method into existing LiDAR SLAM systems yields state-of-the-art performance.
A qualitative exploration of behaviour change and maintenance experience in people with overweight or obesity in a dietary intervention
Authors: Liu Kai , Choi Tammie S.T. , Zhao Lijun , Teong Xiao Tong , Hutchison Amy T. , Heilbronn Leonie K. 
Published: December 2023

AbstractAimThis qualitative study aimed to explore the experiences of participants who were enrolled in 6‐month controlled weight loss interventions with 2‐month follow‐up to better understand the process of behaviour change and maintenance.MethodsFifteen participants who completed or dropped out from either a daily energy restriction or intermittent fasting group were recruited using maximum variation purposive sampling. In‐depth, semi‐structured interviews were conducted at the 2‐month follow‐up phase. All interviews were transcribed and analysed using thematic analysis, guided by behaviour change models including transtheoretical model, social cognitive theory and integrated model of change.ResultsParticipants following both diets showed similar behaviour change patterns. Their first motivations were mostly external and relied on ‘accountability’ to adhere to the diet when initiating the dietary changes. Participants highlighted the importance of frequent reviews and monitoring in assisting their adherence. This feedback system promoted the development of self‐efficacy and internalised motivation to encourage an ‘ownership’. Participants who transitioned successfully from relying on accountability to take ‘ownership’ of the intervention were more capable of tackling challenges and tailoring their diet to form a new routine for long‐term maintenance.ConclusionExternal motivations were key to initiate while internalised motivations were more important to sustain the behaviour change. Health professionals can assist this process through routine monitoring and feedback processes in clinical practice.
Weathered remains: Bioarchaeology, identity, and the landscape
Authors: Ellis Meredith A. B. 
Published: December 2023

AbstractThis article explores the making of identity for two sets of human skeletal remains, labeled 1928 Hurricane Victims 1 and 2 Belle Glade. The remains are so poorly preserved that traditional bioarchaeological analysis to explore their perimortem identity is not possible. However, an exploration of their postmortem identity allows us to examine the relationship between landscape, soil, memory, and bodies in bioarchaeology. This article challenges us to consider how bioarchaeology “makes” identity. It does so against the backdrop of one of the worst natural history disasters in United States history, the 1928 Lake Okeechobee Hurricane in Belle Glade, Florida. The loss of some 2,000 to 3,000 individuals in one night, primarily Black migrant farm laborers, is little remembered in national history, but it profoundly shaped the region, and contributes to an ongoing creation of a category of skeletal remains found in the area even today and labeled hurricane victims.
Care and COVID 19: Lessons for liberals and neoliberals
Authors: Lynch Kathleen 
Published: December 2023

AbstractWithin the liberal political traditions, care is regarded as a private matter, a problem of ethics rather than justice. Social justice is framed as an issue of economics (re/distribution), culture (recognition) and/or politics (representation). The pandemic challenged this liberal patriarchal paradigm; it placed the care relational lives of human beings centre stage in terms of social justice, not only in terms of who did or did not do the caring, who was and was not cared for, but who was capable of caring while balancing paid‐work time with care‐work time. The pandemic also challenged dominant ontological assumptions about the human condition, especially assumptions about invulnerability and autonomy that are so pervasive in a neoliberal capitalist era. The vulnerability of the human body came into sharp relief, especially in Western countries where infectious diseases were assumed to be under control. The autonomy myth was shattered too, as unforeseen and uncontrollable social isolation created emotional and relational vulnerabilities. People learned, often in painful ways how the loss of companionship diminished their sense of who they were. Above all, the pandemic demonstrated that the both the personal and professional care infrastructure of societies is foundational to economic, political, cultural and environmental life. It highlighted how affective equality, that is, equality in the doing and receiving of love care and solidarity, is a key dimension of social justice. Consequently, it taught a lesson on why a care/needs‐based concept of justice is as important as a rights‐based theory and why one is incomplete without the other.
Hybrid human‐porcine factor VIII proteins partially escape the inhibitory effects of anti‐factor VIII inhibitor alloantibodies having A2 or C2 domain specificity
Authors: Mizumachi Kuniyoshi , Nakajima Yuto , Shimonishi Naruto , Furukawa Shoko , Ogiwara Kenichi , Takeyama Masahiro , Nogami Keiji 
Published: December 2023

AbstractIntroductionPorcine factor (pF)VIII has low cross‐reactivity with anti‐human (h)FVIII inhibitor alloantibodies. Clinical trials of pFVIII in congenital haemophilia A patients with inhibitor (PwHA‐I) are in progress. Most polyclonal anti‐hFVIII inhibitors recognize its A2 and/or C2 domain(s), and recombinant human‐porcine hybrid (hp)FVIII proteins may escape neutralization by these inhibitors.AimTo evaluate the ability of hpFVIII to limit the anti‐FVIII activity of inhibitor alloantibodies.MethodsThree hybrid proteins were created by substituting the hFVIII A2, C2 domain or both with the corresponding domains of pFVIII [termed hp(A2), hp(C2) and hp(A2/C2), respectively]. The reactivity of these hybrids was assessed by one‐stage clotting assays (OSA), thrombin generation assays (TGA) and rotational thromboelastometry (ROTEM) by adding them to FVIII‐deficient samples.ResultsOSA demonstrated that the hybrid proteins avoided neutralization by anti‐FVIII A2 or C2 monoclonal antibodies (mAb) and polyclonal inhibitor‐antibodies (polyAb) from PwHA‐I. In TGA, thrombin generation with hp(A2) and hp(A2/C2) was not attenuated in the presence of patient IgG recognizing anti‐A2 domain. In contrast, that with hFVIII and hp(C2) was suppressed by this IgG to levels equivalent to those of FVIII‐deficient plasma. With anti‐A2/C2 polyAb, the activity of hp(A2/C2) was unaffected. ROTEM demonstrated that the addition of hp(A2) or hp(A2/C2) to anti‐A2 polyAb shortened clot times/clot formation times, whilst hFVIII or hp(C2) were ineffective. Similarly with anti‐A2/C2 polyAb, hp(A2/C2) restored coagulation potential to a greater extent than hp(A2) and hp(C2).ConclusionHybrid FVIII proteins containing porcine FVIII A2 and/or C2 domain(s) could support effective therapy in PwHA‐I by avoiding neutralization.
