This study aims to develop a framework to identify the drivers underpinning food tourists' behavioral intentions (BIs). This framework centers on examining how local food consumption value (TLFCV), local food experiential value (TLFEV) and social media influencers (SMIs) impact upon tourists’ attitudes toward local food (ATLF) and food destination image (FDI). The impact of ATLF and FDI on tourists’ BIs is also examined.

PLS-SEM was used to test the hypothesized relationships using survey responses from 379 tourists visiting Rasht, Iran.

The results demonstrate that TLFCV, TLFEV and SMIs can be used to populate a theoretical framework for predicting and understanding the factors influencing tourists’ ATLF and FDI. Specifically, positive ATLF and FDI stimulated positive BIs (e.g., intending to recommend Iranian food to others and intending to revisit Iran in future for culinary tourism purposes).

The findings provide managers and practitioners within the culinary tourism industry with suggestions for how best to strategically market their offerings to increase inbound food tourism.

This study is one of the first to empirically evaluate the drivers of food tourists' BIs, presenting a newly developed model for deployment in future research. Originality is also established by simultaneously investigating TLFCV and TLFEV within the context of food tourism.

The purpose of this study is to organize and analyze the existing literature on co-creation in tourism to identify the state-of-the-art studies and the research gap in this field.

As the research questions seek to provide an overview of the studies in the available literature, the systematic mapping study (SMS) has been selected as the research method. A suitable mapping study method for analyzing and structuring a broad research field concerning methods, designs and research focuses on the existing publications. In total, 137 articles published during 2006–2019 in reliable academic databases such as Science Direct, Emerald, Scopus, Wiley, ProQuest, Sage, Web of Science and Taylor and Francis were selected and analyzed.

The results show a rising trend of published articles in tourism, with the maximum number published in 2019 and the minimum number in 2006. Also, analysis of input articles revealed that most of the studies focused on the antecedents and prerequisites for co-creation and paid less attention to the co-creation context. Other findings show that in the field of tourism, the hospitality sector, especially hotels have paid special attention to co-creation. The majority of papers were the empirical type with quantitative design. Furthermore, most studies used the survey method, while the case study and other methods were the next choices.

This study addresses a major research gap by summarizing the literature related to value co-creation with a specific focus on tourism using the SMS method that provides an overview of the studies in this field. Categorizing papers through SMS helps researchers to review the status of studies in a visual summary to identify gaps and directions for future research.

A wide band perfect THz absorber is presented in this work. The structure includes two layers of graphene disks on the silicon dioxide dielectric layer while a golden plate is placed at the bottom to act as a fully reflecting mirror against THz waves. According to the simulations, the device is robust enough to show independent operation versus layers thicknesses variations, chemical potentials mismatches and changing of electron relaxation time. The designed THz absorber in this work is an appropriate basic block for several applications in THz optical systems such as sensors, detectors and modulators.

The layers in the proposed device are modeled via passive circuit elements and consequently, the equivalent circuit of the device is calculated. Leveraging the developed equivalent circuit model (ECM) and impedance matching concept, the proposed device is designed to perfect absorption with 4.7 THz bandwidth that possesses over 90% absorption. Ample simulations are performed using MATLAB (ECM) and CST (finite element method) to verify the superior performance of the device. According to the simulations, the device is robust enough to show independent operation versus layers thicknesses variations, chemical potentials mismatches and changing of electron relaxation time.

This work reports a wideband THz absorber, composed of two graphene layers. This paper considers the circuit model representation for two different layers of the device. For a unique structure, a highly tunable response versus chemical potential is obtained. The circuit model approach and impedance matching theory are exploited to reduce computational time regarding conventional approaches.

A wide band absorber in THz band is presented. Leveraging circuit model approach and impedance matching theory, the design procedure is simplified regarding CPU time and memory requirements compared to conventional methods. Detailed calculations and ample simulations verify the performance excellency of the device to absorb THz incident waves in 2–6.5 THz frequencies. Also, the robustness of the device is investigated versus parameters mismatches like layers thicknesses and chemical potentials values. According to the simulations and absorption response, the proposed device is an appropriate block to be used in THz optical systems such as detectors, imaging systems and optical modulators.

This study aimed to examine the impact of ICT and digital knowledge on students’ thoughts and beliefs. Using Information and Communication Technology (ICT) in learning and teaching processes can improve the interpretation of knowledge, not only in the learning process but also for thoughts and beliefs. Beliefs and thoughts as propositional content are understood to be a subjective manner of knowing and becoming a focal point of education process. In addition, ICT plays a vital role in enhancing the efficiency of the teaching process which can change the thoughts of learners. So, in this paper, the usage of ICT in education was considered as a key factor for improving students’ thoughts and beliefs. In addition, a conceptual model was proposed to evaluate this impact.

Data were collected from 384 students from secondary schools in Iran. For assessing the elements of the model, a complete questionnaire was designed. For statistical analysis of questionnaires, SPSS 22 and SMART-PLS 3.2 software package was used.

The obtained results showed the high strength of the proposed model. The outcomes indicated that digital technology acceptance positively affects students’ thoughts and beliefs. In addition, the findings showed that the role of digital knowledge, digital training facilities and digital education content on students’ thoughts and beliefs was significant.

The authors deal with one experiment and so the results cannot be generalized. The trail should be repeated with many groups and in diverse contexts.

Despite the importance of the investigating the impact of ICT and digital knowledge on the students’ thoughts and beliefs, the relationship among these factors was not examined well in previous research. Thus, the investigation of the impact of ICT and digital knowledge on the students’ thoughts and beliefs is the main originality of this research. For this goal, a new conceptual model is proposed, which has 11 sub-indicators within four variables: digital technology acceptance, digital knowledge, digital training facilities and digital education content.

This paper aims to review comprehensively the different voltage-boosting techniques and classifies according to their voltage gain, stress on the semiconductor devices, count of the total components and their prominent features. Hence, the focus is on non-isolated step-up converters. The converters categorized are analyzed according to their category with graphical representation.

Many converters have been reported in recent years in the literature to meet our power requirements from mill watts to megawatts. Fast growth in the generation of renewable energy in the past few years has promoted the selection of suitable converters that directly impact the behaviour of renewable energy systems. Step-up converters are a fast-emerging switching power converter in various power supply units. Researchers are more attracted to the derivation of novel topology with a high voltage gain, low voltage and current stress, high efficiency, low cost, etc.

A comparative study is done on critical metrics such as voltage gain, switch voltage stress and component count. Besides, the converters are also summarized based on their advantages and disadvantages. Furthermore, the areas that need to be explored in this field are identified and presented.

Types of analysis usually performed in dc converter and their needs with the areas need to be focused are not yet completely reviewed in most of the articles. This paper gives an eyesight on these topics. This paper will guide the researchers to derive and suggest a suitable topology for the chosen application. Moreover, it can be used as a handbook for studying the various topologies with their shortfalls, which will provide a way for researchers to focus.
