Published: April 2022

Objectives
The objective of this study is to analyze the main patterns of branching of the inferior mesenteric artery (IMA) and to determine if your knowledge changes the surgical strategy in the colorectal cancer.

Methods
This retrospective study included 63 patients with cancer of the sigmoid or rectum. We assessed the patterns of IMA in 3 subtypes: type A (independent left colic artery [LCA]), type B (LCA and sigmoid artery arising in a common trunk) and type C (LCA, sigmoid artery, and superior rectal artery with a common origin). Colorectal surgeons evaluated how the vascular map changed the type of IMA ligation.

Results
Inferior mesenteric artery branching was classified as type A in 55.6% patients, type B in 23.8%, and type C in 20.6%. Knowledge of the vascular map changed the type of ligation from high to low in 20 of the 50 patients who were candidates for surgery. The change was possible in tumors located in the sigmoid colon and the rectosigmoid junction with the type A or B branching.

Conclusions
Preoperative Multidetector Computed Tomography angiography can define the pattern of IMA branching. Based on this information, a low ligation can be performed in tumors located in sigmoid colon and rectosigmoid junction with IMA branching types A and B.
Systematic search for extreme and singular behaviour in some fundamental models of fluid mechanics
Authors: Protas Bartosz 
Published: April 2022

This review article offers a survey of the research program focused on a systematic computational search for extreme and potentially singular behaviour in hydrodynamic models motivated by open questions concerning the possibility of a finite-time blow-up in the solutions of the Navier–Stokes system. Inspired by the seminal work of Lu & Doering (2008Ind. Univ. Math.57, 2693–2727), we sought such extreme behaviour by solving PDE optimization problems with objective functionals chosen based on certain conditional regularity results anda prioriestimates available for different models. No evidence for singularity formation was found in extreme Navier–Stokes flows constructed in this manner in three dimensions. We also discuss the results obtained for one-dimensional Burgers and two-dimensional Navier–Stokes systems, and while singularities are ruled out in these flows, the results presented provide interesting insights about sharpness of different energy-type estimates known for these systems. Connections to other bounding techniques are also briefly discussed.This article is part of the theme issue ‘Mathematical problems in physical fluid dynamics (part 1)’.
Steady thermal convection representing the ultimate scaling
Authors: Motoki Shingo , Kawahara Genta , Shimizu Masaki 
Published: April 2022

Nonlinear simple invariant solutions representing the ultimate scaling have been discovered to the Navier–Stokes equations for thermal convection between horizontal no-slip permeable walls with a distanceHand a constant temperature differenceΔT. On the permeable walls, the vertical transpiration velocity is assumed to be proportional to the local pressure fluctuations, i.e.w=±βp/ρ(Jiménezet al.2001J. Fluid Mech.,442, 89–117. (doi:10.1017/S0022112001004888)). Two-dimensional steady solutions bifurcating from a conduction state have been obtained using a Newton–Krylov iteration up to the Rayleigh numberRa∼108for the Prandtl numberPr=1, the horizontal periodL/H=2and the permeability parameterβU=0–3,Ubeing the buoyancy-induced terminal velocity. The wall permeability has a significant impact on the onset and the scaling properties of the found steady ‘wall-bounded’ thermal convection. The ultimate scalingNu∼Ra1/2has been observed forβU>0at highRa, whereNuis the Nusselt number. In the steady ultimate state, large-scale thermal plumes fully extend from one wall to the other, inducing the strong vertical velocity comparable with the terminal velocityUas well as intense temperature variation ofO(ΔT)even in the bulk region. As a consequence, the wall-to-wall heat flux scales withUΔTindependent of thermal diffusivity, although the heat transfer on the walls is dominated by thermal conduction.This article is part of the theme issue ‘Mathematical problems in physical fluid dynamics (part 1)’.

Authors: De Cianni Rachele , Pippinato Liam , Zanchini Raffaele , Brun Filippo , Di Vita Giuseppe , Mancuso Teresina 
Published: April 2022

PurposeThe objective of this study is to investigate the role of mothers in administering afternoon snacks to children aged between 6 and 10. Through an exploratory analysis, this study aims at identifying how sociodemographic characteristics of mothers and children and objective and subjective nutritional awareness of the parent influences healthy or unhealthy food choices for the children.Design/methodology/approachAn online survey was submitted to 242 mothers of children attending primary school. Non-parametric correlation using Spearman's coefficient was adopted as an exploratory analysis tool.FindingsThe analysis shows that the mothers' level of education and income influence the purchase of snack products. More permissive parents tend to be less well-off, have more than one child and also purchase sweet treats, salty snacks, and sugary drinks more frequently. Furthermore, the results show that parents' perceived subjective awareness is actually lower than their objective awareness, but also that both types of knowledge positively influence the purchase of healthy snacks.Originality/valueThere is extensive research documenting the importance of parents in reducing the risk of obesity; however, their influence on snack intake has not been widely discussed. Furthermore, the association between the occurrence of obesity and parents' behaviour regarding their children's snacking remains unclear. To bridge this gap, this study focuses on a meal which is often linked to poor eating habits: the afternoon snack.
Firm-serving or public-serving? Analyzing public responses to employee volunteer program communication
Authors: Shi Duli 
Published: April 2022

PurposeDrawing on the elaboration likelihood model, this study aims to examine how employee volunteer program (EVP) type, corporate visual identity, and issue involvement affect external publics' attributions of EVPs and attitudes toward the company.Design/methodology/approachA 2 (EVP type: skills-based vs. not-skills-based) × 2 (salience of corporate visual identity: high vs. low) randomized experiment was conducted with 157 participants from Amazon's Mechanical Turk. A fictitious company and its EVP messages were created to control for the company's existing reputation and participants' past experiences with the company.FindingsParticipants responded positively toward EVP messages regardless of the EVP type. However, salient corporate visual identity significantly aroused participants' more attributed firm-serving motives, which led to more negative attitudes toward the company. Next, issue involvement presented its value in EVP communication as highly involved participants displayed favorable attributions of EVPs and positive attitudes toward the company.Originality/valueThis study approaches EVPs as an important CSR practice and expands the discussion on strategic CSR communication by uncovering the roles of central and peripheral cues in public responses to EVP messages. Moreover, the findings highlight the importance of fostering and enhancing publics' issue involvement in achieving successful EVP communication.
The role of contract incompleteness factors in project disputes: a hybrid fuzzy multi-criteria decision approach
Authors: Gurgun Asli Pelin , Koc Kerim 
Published: April 2022

PurposeContract incompleteness with deficiency, inconsistency, defectiveness, and ambiguity in contract clauses, which can cause misunderstandings and misinterpretations, may result with disputes in projects. This study aims to investigate contract incompleteness factors with a hybrid fuzzy multi-criteria decision approach.Design/methodology/approachContract incompleteness factors were ranked by fuzzy VIKOR (Visekriterijumska Optimizacija I Kompromisno Resenje) method, and the most significant factors were subjected to fuzzy decision-making trial and evaluation laboratory (DEMATEL) to examine their causal relationships. The study is not limited to ranking the identified factors solely, since their cause-effect interactions are also essential for proper risk management in construction projects.FindingsHybrid use of multi-criteria analysis reveals that ambiguity in enforceability including excessive demands and significant amendments in the scope of works are the top two causal contract incompleteness factors, while lack of implementation details and focus of focal point, and insufficient supporting and technical documents are the most affected ones.Originality/valueContractual causes of disputes due to contract incompleteness factors other than requirements of the contracts have been rarely investigated in the literature. The research is one of the first studies in the literature investigating the causal relationship among factors in construction contracts, which might lead to project disputes. Findings are expected to improve contract drafting, eventually contributing to effective risk management in construction projects.
Exploring consumer constructions of local food: meanings and influences
Authors: Banerjee Rajlakshmi , Quinn Barry 
Published: April 2022

Purpose
This study aims to focus on local food consumption and specifically seeks to explore how consumers construct the meaning of local food and the nature of relationships between key influences on the local food purchase intention.

Design/methodology/approach
A two-stage qualitative methodology was adopted consisting of five focus group discussions and 25 semi-structured interviews with consumers in Northern Ireland. Focus groups explored consumer meanings of local food. Semi-structured interviews sought to explore in more depth the inter-relationships between the influences on the purchase intention and the role of moral norms.

Findings
Five key influences on the purchase intention are identified (quality attributes, experience and familiarity, emotional attributes, the setting, support for the local economy). These influences are connected with a range of self-interest, altruistic and moral factors.

Research limitations/implications
This study was undertaken in a specific geographical setting and thus the generalisation of the findings is limited. Future research should ascertain the views of stakeholders (producers and retailers) to provide multi-actor constructions and understandings of local food.

Practical implications
There are a number of practical implications for marketers from this study that provide considerable scope to differentiate local food products. A more nuanced understanding of consumer motivations and their understanding of local food will help marketers to develop brand image linked to the themes identified here such as product familiarity and rural connections. Furthermore, the local food servicescape or setting should be managed carefully to construct an emotional attachment and positive consumer experience, whilst promoting trust and perceptions of quality.

Originality/value
Previous studies on local food consumer behaviour have considered the influences on local food consumer behaviour in quite binary terms (self-interest and altruistic factors). This study unpicks the key influences on the purchase intention, based on a thematic analysis, and proposes a new categorisation and set of interrelationships around five key themes.
Design thinking: a cognitive resource for improving workforce analytics and training evaluation
Authors: Zafar Natasha , Asadullah Muhammad Ali , Haq Muhammad Zia Ul , Siddiquei Ahmad Nabeel , Nazir Sajjad 
Published: April 2022

Purpose
The firms use training evaluation practices (TEPs) to determine the return of billions of dollars spent on employee training and development activities. The firms need to modernize the set of TEPs for evidence-based workforce management decisions. This study aims to examine a mediation mechanism to explain how human resource (HR) professionals’ design thinking (DT) mindset strengthens the set of TEPs using predictive workforce analytics (PWAs).

Design/methodology/approach
The authors used SPSS computational named MLMED to test the proposed relationships by collecting data from 180 management professionals serving in subsidiaries of multinational corporations in Pakistan.

Findings
The statistical results demonstrated that DT is not directly related to firms’ TEPs. However, the statistical results supported the mediating role of firms’ use of PWAs between DT and TEPs.

Originality/value
The findings offer a new perspective for firms to use HR professionals’ DT mindset for modernizing the set of existing HR practices.
A study to explore the linkage between green training and sustainable organizational performance through emotional intelligence and green work life balance
Authors: Deshpande Pallavi , Srivastava Anugamini Priya 
Published: April 2022

Purpose
This study aims to review the role of green training and green work life balance (GWLB) on sustainable organizational performance (SOP) with a moderating variable “Emotional Intelligence” (EI).

Design/methodology/approach
For the development of the construct of the present study, a Scopus database was selected and research papers published in indexed journals were considered. Relevant keywords were selected and literature was searched on green training, EI, SOP, GWLB. The literature was reviewed to find out the linkage and possibility of development of integrated model. The main focus was on highlighting the relevance of green training on GWLB and its influence on SOP.

Findings
SOP can be achieved with the intervention of EI and GWLB; further green training is one of the influential practices of human resource development (HRD) which helps to develop the green behavior.

Research limitations/implications
It can give new insight to the organization for application of green human resource practices for SOP. Development and designing the cohesive environmental work culture and willingness to protect environment through green training can be implemented by HRD. Perhaps, the application of green training encourages GWLB.

Practical implications
Quantitative research and cross sectional study is required to find out the intervening role of EI and work–life balance between green training and SOP across a broader range of sectors.

Originality/value
This research extends the literature review and developed a new integrated model which shows the link between green training and SOP.
Do multilingual employees better adjust to work environment changes? Examining the case of a credit union during the COVID-19 pandemic
Authors: Veach Timothy , Yoon Yeongjoon , Iglesias John D. 
Published: April 2022

Purpose
Organizations have been challenged to identify antecedents to improved employee adjustment to the work environment changes that arose in the wake of the COVID-19 global pandemic. This study aims to explore the effect of multilingualism on employee ability to adjust to workplace changes based on the concept that multilinguals have been found to switch between tasks more efficiently as compared to monolinguals.

Design/methodology/approach
Applying a sequential explanatory mixed methods research approach, quantitative performance evaluation data on 207 credit union employees is analyzed using hierarchical linear modeling to predict employee performance, and thematic analysis of qualitative data representing the adjustment narratives of six monolingual and six multilingual employees within the sample is conducted, corresponding to the period during which employees were adjusting to broad workplace changes after the onset of the global pandemic.

Findings
The results suggest greater predicted improvement in the performance of multilingual employees. Reliance on the task-switching ability associated with multilingualism is found to be the primary self-evaluative factor for successful change adjustment among multilingual employees.

Practical implications
In light of work performance benefits identified in this study, organizations may consider multilingualism as a characteristic preceding better adjustment to organizational change, and not simply as a skill applicable to tasks requiring language proficiency, suggesting practical implications for human resource and organizational management.

Originality/value
This is the first sequential explanatory study focusing on the task-switching ability of multilinguals as an antecedent to change adjustment evidenced by improved work performance within an organizational context.
The soft skills bases in digital academic entrepreneurship in relation to digital transformation
Authors: Garcez Ana , Franco Mário , Silva Ricardo 
Published: April 2022

PurposeDigital technology changes the organizational structure of traditional firms, creating opportunities for entrepreneurship. These modifications are known as “digital transformation” (DT). In addition, higher education institutions (HEIs) are altering the form of student–lecturer and teaching–learning interaction, where DT restructures the bases of soft skills (SS). Since SS are difficult to measure, this study aims to analyze the bases of SS for digital academic entrepreneurship, responding to the following research question: What are the bases of digital academic entrepreneurship and how are they formed?Design/methodology/approachAn extensive integrative review of the literature revealed that due to the editable, re-combinable, reprogrammable and generating nature of digital technology, the basis of DT, it is necessary to develop SS in higher education students.FindingsThe results show that the competencies can be developed considering three major groupings: (1) individual characteristics, (2) cultural characteristics and (3) knowledge sharing.Practical implicationsSince SS are not easily taught, this study shows how the use of digital tools can help and support this type of process. It is suggested, therefore, that those in charge of HEIs should use the pillars presented in the framework proposed here to guide their institutions' strategic planning. With these pillars in mind, the aim is to stimulate an entrepreneurial mentality in students and develop digital academic entrepreneurship.Originality/valueAn innovative conceptual model of digital academic entrepreneurship is proposed from the perspective of SS, where the interlinking of those groupings is permeated by DT, as well as the disruptive role of digital technology, leading to the development of an entrepreneurial mentality in HEI students.
Incorporating multidimensional images into cultural heritage destination: does it help to explain and analyse better?
Authors: Lam Jason M.S. , Makhbul Zafir Khan Mohamed , Aziz Norzalita Abd , Ahmat Mohd Amirul Hafidz 
Published: April 2022

PurposeThe present study aims to examine and explain cultural heritage destination by applying multiple dimension image model (cognitive–affective–conative aspects).Design/methodology/approachA total of 233 international heritage-based tourists were surveyed on-site at some of the most prominent historical attractions in Malacca, one of the first cities in Malaysia declared as a UNESCO World Heritage Site. The covariance-based structural equation modelling was applied to examine the hypotheses.FindingsThe structural equation modelling validated that cognitive image aspects such as living culture, intangible and tangible are affected positively. The effects are statistically significant for conative and affective images. On the other hand, cognitive tangible image is an aspect that impacted affective image to a lesser degree than conative image. Whereas affective image attributes were found to have significant and positive influence on conative image.Originality/valueThis study enriches the limited empirical research study on heritage image conceptualisation by expanding into tri-component model. The destination image has garnered a great deal of attention, particularly due to its significant and impactful influence on the decision-making and the sustainable behaviour of tourists, and it has since become the subject of many studies in the tourism and hospitality literatures. But most research concerning heritage image for destinations has considered the construct uni-dimensionally.
The heuristics applied by tech entrepreneurs in the Middle East during opportunity evaluation
Authors: Hjeij Mohamad 
Published: April 2022

Purpose
This study aims to explore the heuristics applied by tech entrepreneurs in the Middle East during the opportunity evaluation process.

Design/methodology/approach
A multiple case-based methodology was applied, which consisted of semi-structured interviews with entrepreneurial experts from different cities in the Middle East. Qualitative data analysis was then performed with inductive thematic coding using the Eisenhardt method.

Findings
The results suggest that entrepreneurs mostly use six heuristics to evaluate opportunities quickly. Three of them are related to the opportunity as an abstract idea, and three are connected with the person (s) involved in the opportunity. In addition, entrepreneurs in the Middle East were more interested in the personal characteristics of the opportunity presenter than in the opportunity itself.

Research limitations/implications
Identifying the heuristics applied by experts may neglect the perspective of the community of entrepreneurs as a whole. Hence, future research should target a wider segment of entrepreneurs. Furthermore, the effect of applying such heuristics on the strategic growth of startups remains an open question.

Practical implications
The identified heuristics are aligned with the hands-on approach of entrepreneurship and can be applied as a decision-making technique for aspiring entrepreneurs who seek to succeed in this region.

Originality/value
This study explores the under-examined topic of heuristics in opportunity evaluation within the regional context of the Middle East, which has also been scarcely investigated. It sheds light on the importance of cultural factors in identifying the cognitive shortcuts used in a business context.
Whether family ownership affects the relationship between CSR and EM: evidence from Chinese listed firms
Authors: Rahman Md Jahidur , Zheng Xinying 
Published: April 2022

PurposeThis study explores the relationship between corporate social responsibility (CSR) and earnings management (EM) in China and whether family ownership impacts this relationship.Design/methodology/approachThe research data are the financial reports and CSR disclosure reports of Chinese listed companies from the CSMAR database for the 2010–2020 period. Ordinary least squares (OLS) regression was used to analyze the relationship between various variables in this study.FindingsResults show that CSR significantly and positively affects accrual-based EM (AEM) but does not affect real EM (REM). Moreover, family ownership influences the positive relationship between CSR and AEM. Compared with non-family enterprises, family enterprises tend to disclose less CSR performance but also have lower AEM behavior.Originality/valueThis result is related to the information transparency of listed enterprises and Socioemotional Wealth theory. This study provides reference for domestic and foreign investors and other stakeholders in understanding the impact of family ownership on the relationship between CSR and earnings management to optimize their investment decisions.
