Eating patterns around the world have changed considerably, including food choices and preparation. One of these alterations in food consumption patterns is an increase in desire for fast-food consumption, which has been associated with poor diet quality. In order to analyze consumers’ food consumption behaviors, it is necessary to account for psychological factors (e.g. attitudes) that shape behaviors. Thus, the purpose of this paper is to explore influencing factors on the attitudes of consumers in Isfahan City toward fast-food consumption, so as to understand why consumers use fast-food despite widespread knowledge of the negative health consequences.

The predominant paradigm of the present study was quantitative, in that it was a correlational survey. The population of this study consisted of consumers who lived in Isfahan city in June 2015. A total sample of 350 people was selected using convenience sampling. Data were collected through a face-to-face interview with the consumers using a researcher-made questionnaire. Analysis was conducted using SPSS (V20) and AMOS (V20) software and a set of correlation and differential tests.

The results revealed that “health consciousness” and “trust” are the main effective factors on the attitudes of the respondents. The results also revealed that the elder and married respondents have more positive attitudes toward fast-food consumption.

It is worth mentioning that fast-food has become an important part of the Iranian diet. These findings have both academic and policy implications. The results showed that the need for much more consumer education regarding fast-food and mass media could effectively be used. Further, the government should support and subsidize fast-food restaurants so that they may produce healthier food options.

Lean construction (LC) consists of very effective techniques; however, its implementation varies considerably from one industry to another. Although numerous lean initiatives do exist in the construction industry, the research topic related to LC implementation is still unexplored due to the scarcity of validated assessment frameworks. This study aims to provide the first attempt in developing a structural model for successful LC implementation.

This study developed a Lean construction model (LCM) by critically reviewing seven previous LC frameworks from different countries, defining 18 subprinciples grouped into 6 major principles and formulating testable hypotheses. The questionnaire was pre-tested with 12 construction management experts and revised by 4 specialized academics. A pilot study with 20 construction units enhanced content reliability. Data from 307 Moroccan construction companies were collected to develop a measurement model. SPSS V. 26 was used for Exploratory Factor Analysis, followed by confirmatory factor analysis using AMOS version 23. Finally, a structural equation model statistically assessed each construct's contribution to the success of LC implementation.

This work led to the development of an original LCM based on valid and reliable LC constructs, consisting of 18 measurement items grouped into 6 LC principles: Process Transparency, People involvement, Waste elimination, Planning and Continuous improvement, Client Focus and Material/information flow and pull. According to the structural model, LC implementation success is positively influenced by Planning and Scheduling/continuous improvement (β = 0.930), followed by Elimination of waste (β = 0.896). Process transparency ranks third (β = 0.858). The study demonstrates that all these factors are mutually complementary, highlighting a positive relationship between LC implementation success and the holistic application of all LC principles.

To the best of the authors’ knowledge, this study is the first attempt to develop a statistically proven model of LC based on structural equation modelling analysis, which is promising for stimulating construction practitioners and researchers for more empirical studies in different countries to obtain a more accurate reflection of LC implementation. Moreover, the paper proposes recommendations to help policymakers, academics and practitioners anticipate the key success drivers for more successful LC implementation.

The main purpose of this paper is to present lean implementation in hospital supply chain management (HSCM) and propose a new conceptual framework tailored specifically to the needs of Saudi health-care organizations.

This paper starts with an in-depth review of existing frameworks or models for lean implementation in health care in general and in HSCM specifically. Based on the literature studies and taking experts’ opinions into account, a new framework for lean implementation in the Saudi HSCM is presented.

A new lean implementation framework is offered to decision-makers in the health-care organization for implementing a lean approach in HSCM practices.

This study focused on health-care organizations, which were selected from hospitals operated by the Ministry of Health and only those hospitals that are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The framework is limited to Saudi health care.

The lean supply chain management (LSCM) framework is easy to understand and use without much complexity. This simplicity makes the LSCM applicable in health-care settings. Further, LSCM was validated in three different hospitals, and it helped them to identify and improve their non-added activities, thereby readying them for lean deployment in HSCM.

Little attention has been paid to implementing a lean approach by health-care providers in developing countries. This study presents a new framework that is considered the first of its kind for implementing lean in HSCM in Saudi. This framework could help HSCMs’ decision-makers to implement lean successfully in HSCM practices.

This paper aims to analyze the stability of laminated shells subjected to axial loads or external pressure with considering various geometries and boundary conditions. The main aim of the present study is developing an efficient combined method which uses the advantages of different methods, such as finite element method (FEM) and isogeometric analysis (IGA), to achieve multipurpose targets. Two types of material including laminated composite and sandwich functionally graded material are considered.

A novel type of finite strip method called isogeometric B3-spline finite strip method (IG-SFSM) is used to solve the eigenvalue buckling problem. IG-SFSM uses B3-spline basis functions to interpolate the buckling displacements and mapping operations in the longitudinal direction of the strips, whereas the Lagrangian functions are used in transverse direction. The current presented IG-SFSM is formulated based on the degenerated shell method.

The buckling behavior of laminated shells is discussed by solving several examples corresponding to shells with various geometries, boundary conditions and material properties. The effects of mechanical and geometrical properties on critical loads of shells are investigated using the related results obtained by IG-SFSM.

This paper shows that the proposed IG-SFSM leads to the critical loads with an approved accuracy comparing with the same examples extracted from the literature. Moreover, it leads to a high level of convergence rate and low cost of solving the stability problems in comparison to the FEM.

The purpose of this paper is to develop an effective framework for implementing Lean strategies in small- and medium-sized enterprises (SMEs) in the Kurdistan Region of Iraq (KRI).

Based on the integration of LM tools and techniques with the Malcolm Baldrige National Quality Award (MBNQA) criteria a systematic Lean implementation framework for manufacturing SMEs has been proposed. The core values, drivers and tools of the proposed framework were further developed based on case studies in three SMEs in the KRI.

Proposed framework is able to provide a simple pathway for SMEs to systematically implement Lean techniques in seven functional areas in order to create Lean culture in the organisation. Business performance measurement in terms of profitability, customer satisfaction, employee’s satisfaction, competitiveness growth and ergonomic improvement is presented in favour of evaluating Lean outcomes appropriately. It also presents the experience of small firms in implementing Lean programmes to show that Lean is valid in SMEs.

The framework concentrates only on the internal issues of the organisation, while external variables such as national culture and external support are excluded.

The framework assists improvements in SMEs that either initially attempt to start Lean journey or those that are at more advanced levels towards excellent-Lean manufacturing. The framework can also be used as a self-assessment model to determine the degree of Lean readiness.

To the best knowledge of the author, it is the first framework that integrates Lean techniques with MBNQA criteria to support Lean implementation in SMEs. It is also the first study regarding Lean-excellence in the KRI.

In the modern manufacturing environment, it is imperative to apply the manufacturing concepts of lean, agile, resilient and green, collectively known as LARG manufacturing, to achieve excellence in which lean manufacturing eliminates wastes; agile manufacturing makes processes fast, efficient and flexible; resilient paradigm deals with countering the uncertainty while green manufacturing improves environmental performance. The objective of this study is to develop an integration framework that synergizes LARG manufacturing with Industry 4.0.

Through a literature review, the authors have explored the possibility of collaboration between constituents of lean, agile, resilient and green manufacturing with the facets of Industry 4.0.

The authors have developed a comprehensive integration framework that has been divided into 11 phases and 31 steps in which the various Industry 4.0 facets have supplemented the lean, agile, resilient and green paradigms.

This investigation and adoption of technologically intensive automation shall provide clarity to practitioners regarding the synergy of LARG manufacturing & Industry 4.0, so that fast and efficient manufacturing processes can be achieved.

The framework provides detailed insight towards implementation of LARG practices in a manufacturing organization in coalescence with Industry 4.0 practices.

The purpose of this paper is to investigate the factors affecting anti-consumption behavior of the consumers toward organic food purchase: in particular, how do individual beliefs about trustworthiness of organic foods, normative structure of social pressure and self-efficacy affect individual intentions to make organic food purchases and actual purchasing behavior? To answer this question, a theoretical framework of the theory of planned behavior (TPB) as its foundation has been established. Using measurement scales in order to measure different aspects of trustworthiness, normative structure, self-efficacy, attitude, perceived behavioral control (PBC) and subjective norms, a survey instrument has been developed to examine the several associations implied by the model of TPB.

In doing so, data on a structured questionnaire were collected from various parts of a city based on convenience random sampling procedure. The respondents were interviewed face-to-face to collect information on a structured questionnaire. Data (n=337) were analyzed using a research framework formulated based on the TPB through the structural equation modeling procedure.

The findings of the study indicate that among the seven independent variables of trustworthiness, normative structure, self-efficacy, attitude, subjective norm and PBC, only subjective norm has not been statistically significant to influence organic food purchase behavior.

The result implies that various sociopolitical forces and skewed monthly incomes are inhibiting the consumers (anti-consumption) to increasingly buy the organic food products.

In this regard, government, policy planners, academia as well as media have profound roles to play to encourage people to buy more organic food for their health safety and overall consumer well-being.

This research is based on primary data collected from the respondents of a sub-urban areas of a metropolitan city. The findings will help formulate a sound food policy for ensuring social well-being of the consumers.

The purpose of this paper is to empirically examine lean manufacturing (LM) practices and to quantify their impact on business performance (BP), with particular emphasis on the mediating role of operational performance (OP) in deriving the BP benefits commonly linked with LM. It also seeks to identify those lean practices most appropriate for application.

Empirical data on LM practices were collected using a structured survey questionnaire. The sampling frame was Jordanian companies registered and listed by the Amman Chamber of Commerce. In total, 500 questionnaires were distributed among 300 companies and a total of 249 completed questionnaires were eligible for statistical processing, a response rate of 49.8 percent. Invalid questionnaires were eliminated, leaving 228 usable. The theoretical relations were tested by structural equation modeling.

Although the results of the statistical analysis indicate a positive and significant impact of implementing LM practices on both OP and BP, they also show that the various LM practices did not receive equal recognition among the organizations surveyed. The most commonly adopted lean principles were found to be total preventive maintenance, statistical process control and housekeeping 5S.

Other lean practices have not been considered as a dimension in this study. However, it opens new avenues of investigation relevant to lean practices.

The most significant implication of the study is that managers in manufacturing firms should place more emphasis on LM practices when developing strategies for leveraging performance. The study shows that the LM approach contributes to BP when LM practices are simultaneously implemented.

The originality of this study lies in the new context in which it was conducted. The study adds value by investigating the implementation of LM practices which have been transferred from developed to developing countries and by empirically examining their impact on key performance indicators within the Jordanian manufacturing sector.
