Abstract
The finite element solution of turbulent flows using a (k‐ε) turbulence model usually presents severe numerical difficulties. Develops an iterative (k‐L)‐predictor/ε‐corrector algorithm for overcoming this and solving the (k‐ε) turbulent models. The iterative scheme achieves convergence in L (length scale) which is proportional to (k1.5/ε). Numerical results indicate that the developed iterative algorithm is very robust.

Abstract
Purpose
The artisanal cheese industry in the Community of Madrid (CM) in Spain has recently experienced an increased development despite its traditionally limited cheese and milk production. The purpose of this paper is to explain this phenomenon by identifying the determinants of consumer attitudes towards cheese consumption in relation to the offer provided by recent artisan cheese producers.
Design/methodology/approach
A phone survey (n = 1,111 consumers) consisting of 17 questions was carried out to analyse cheese consumption culture in the CM. Principal component analysis was used to identify the factors that determine cheese-purchasing variance.
Findings
The first component was explained by hedonic (38 per cent of variance), followed by health aspects (24 per cent of variance) and price (15 per cent of variance). Price was identified as the most important criterion when purchasing cheese (67 per cent of consumers), followed by fat (57 per cent) and salt content (56 per cent). Results indicate a low cheese consumption culture in Madrid, as 48 per cent of consumers did not know exactly what kind of cheese they normally consumed. The type of milk used in cheese production was used to identify consumer profiles for market segmentation. Sheep and goat cheese consumers valued local production food quality and may be the driving force behind the expansion of artisanal cheese industry in Madrid.
Research limitations/implications
Madrid Region is one of the most important markets in Spain and Europe; however, local cheeses are not a traditional product in the market.
Practical implications
This paper offers a very interesting approach about how consumers’ culture can support a new local agricultural industry.
Social implications
Rural entrepreneurs can innovate focussing on new consumers demands. Local and handcrafted products are an opportunity in rural and periurban areas.
Originality/value
This paper shows consumer preferences and attitudes towards the novel artisan cheese sector that has expanded in the CM.

Abstract
Purpose
This study examines how social influences (need to belong and fear of missing out) and the perceived credibility of health claims affect the intention to purchase foods with health claims.
Design/methodology/approach
Data were obtained from a web-based survey of 844 Spaniards aged 25 years and older, with sex and age quotas. Real product images with health claims contextualized the purchase intention questions, aiding respondents who often struggle to differentiate health from promotional claims.
Findings
Both personal and social dimensions of fear of missing out (FoMO) influence the desire to belong to a healthy group. The intention to purchase food with health claims is also positively associated with the desire to belong. The results reflect the importance of FoMO and the need to belong in enhancing consumers’ tendency to purchase products with health claims. The results also reflect the importance of purchase intention in making health claims perceived as credible.
Originality/value
This study integrates individual aspects (belief in the credibility of health claims) with social aspects (belonging and FoMO) to analyze the intention to purchase foods with health claims. Using authentic product images to aid consumer comprehension adds an innovative dimension, addressing a gap in consumer behavior research.
研究目的
本研究擬探討社會影響(歸屬的需要和錯失機會的恐懼)和保健聲稱的感知可信性,會如何影響消費者購買附有保健聲稱食品的意向。
研究設計
數據取自一個網上調查,研究人員調查了844名年齡為25歲或以上的西班牙人,調查設有性別和年齡的配額。研究人員使用附有保健聲稱的真實產品形象,來設計與情境相配合關於購買意向的問題,這對難於把保健聲稱與促銷聲稱區分的應答者來說是有幫助的。
研究結果
恐懼錯失機會的個人維度和社會維度兩者均會影響想隸屬於保健團體的渴望; 而消費者購買附有保健聲稱食品的意向又與這渴望成正相關。 研究結果顯示,就增強消費者購買附有保健聲稱產品的意向而言,錯失機會的恐懼,以及想隸屬的渴求均有其重要性。 研究結果亦顯示,若要為保健聲稱建立可信的聲譽,購買意向是重要的因素。
研究的原創性
本研究透過合併個人層面 (對保健聲稱可信性的信任)與社會層面 (歸屬感和錯失機會的恐懼),來分析消費者購買附有保健聲稱食品的意向。研究人員使用真實的產品形象,以幫助消費者理解,就此而言,這為消費者行為研究填補了空白,成為一個創新的維度。

Abstract
Purpose
A food safety management system (FSMS) is a dynamic resource with the potential to generate competitive advantages, whose implementation may be certified according to internationally recognised standards such as the Brand Reputation Compliance Global Standards (BRCGS). This research sets out to discover why companies implement these systems and the influence each one of them exerts.
Design/methodology/approach
Data have been gathered via a questionnaire administered in Spanish-speaking countries on both sides of the Atlantic, compiling a sample of 574 companies certified to BRCGS. The hypotheses formulated were verified by structural equation modelling.
Findings
The analysis reveals a four-dimensional motivational structure (ethics, efficiency, commercial and legitimacy) and three dimensions for the implementation of the FSMS (food safety management, analysis of hazards and control points and best practices). Motivations of an ethical and commercial nature have a positive effect on the degree of effective implementation, while those based on the search for legitimacy reveal a negative relationship.
Originality/value
While most of the studies on the implementation of management systems are based on a dichotomous measurement of this process (companies with a management system compared to those without one, or companies certified according to a standard compared to those that are not), this study uses a continuous variable of the degree of effective implementation of the system's different dimensions or components. Little has so far been reported about why companies implement an FSMS, and here we not only identify their reasons but also assess those dimensions with the greatest impact.

Abstract
Purpose
This paper aims to systematically review the literature on quality management in agri-food supply chains (SCs) and propose an integrated conceptual framework.
Design/methodology/approach
A systematic literature review that analyses 93 papers in peer-reviewed academic journals published from 1996 to November 2021 is conducted. A conceptual model is advanced.
Findings
Based on a hierarchy of capabilities perspective, the authors develop an integrated conceptual framework in which SC quality (SCQ) management practices promote three levels of SC dynamic capabilities, which in turn lead to agri-food SCQ performance.
Originality/value
The authors propose a hierarchy of capabilities perspective of quality management in agri-food SCs and develop a conceptual framework. Furthermore, a number of propositions based on dynamic capabilities and the review findings are provided. Four future research directions are presented.

Abstract
Purpose
The purpose of this paper is to develop measurement scales for customer contact in a technology-generated context.
Design/methodology/approach
The authors adapted the scales of Froehle and Roth (2004), by following a systematic scale adaptation and development process. The adapted scales were tested for psychometric properties and refined by building measurement models using partial least squares structural equation modeling.
Findings
The authors found it necessary to revise Froehle and Roth’s (2004) original items in most of the scales. After testing, the “attitude towards the episode” scale was dropped and remaining nine scales were retained.
Research limitations/implications
The scales will be useful to future researchers on online shopping to advance their research. The scales can be tested and validated with data from multiple empirical contexts and adapted to those contexts as necessary. Future studies must examine path relationships between belief, attitude, and intention constructs.
Practical implications
The adapted scales can be useful to practitioners in the domain of online shopping to measure the beliefs, attitudes, and intentions of their customers. Potential beneficiaries include service providers, service designers, industry associations as well as regulators in the government.
Originality/value
The overarching contribution of this paper lies in developing scales pertaining to the online shopping context of technology-generated customer contact. The paper has simultaneously addressed two relatively less attended areas of research on service operations – the role of technology in customer contact and measurement of customer contact.

Abstract
Purpose
This study aims to address challenges related to long lead time within a hazelnut company, primarily attributed to product quality issues. The purpose is to propose an integrated lean-based methodology incorporating a continuous improvement cycle, drawing on Lean Six Sigma (LSS) and Industry 4.0 applications.
Design/methodology/approach
The research adopts a systematic approach, commencing with a current state analysis using VSM and fishbone analysis to identify underlying problems causing long lead time. A Pareto analysis categorizes these problems, distinguishing between supplier-related issues and deficiencies in lean applications. Lean tools are initially implemented, followed by a future state VSM. Supplier-related issues are then addressed, employing root cause analyses and Industry 4.0-based countermeasures, including a proposed supplier selection model.
Findings
The study reveals that, despite initial lean implementations, lead times remain high. Addressing supplier-related issues, particularly through the proposed supplier selection model, significantly reduces the number of suppliers and contributes to lead time reduction. Industry 4.0-based countermeasures ensure traceability and strengthen supplier relationships.
Originality/value
This research introduces a comprehensive LSS methodology, practically demonstrating the application of various tools and providing managerial insights for practitioners and policymakers. The study contributes theoretically by addressing challenges comprehensively, practically by showcasing tool applications and managerially by offering guidance for system performance enhancement.
