Abstract
Purpose
A significant challenge arises from the inconsistent terminology used to describe augmented reality (AR) technology, leading to confusion and hindered communication. The purpose of this paper is to address the absence of a comprehensive taxonomy to define AR use cases in the architecture, engineering, construction and operation (AECO) domain and present a structured approach to developing one.
Design/methodology/approach
A literature review was conducted to identify AR use cases and use case taxonomies in the AECO and other industry domains in the Compendex database. This review resulted in the identification of 315 AR use cases. From the identified taxonomies, one was selected based on its comprehensiveness, relevance and applicability to the AECO industry. Leveraging this taxonomy from the manufacturing domain, this study validated, refined and added classes to the taxonomy through a content analysis of the existing AECO AR use cases. Additional critical categories were identified from existing taxonomies to enhance the taxonomy. A subset of 63 use cases was then used to validate the refined taxonomy.
Findings
The resulting taxonomy comprises two main dimensions: context-related and technology-related. The context-related dimension encompasses six classes, including the field of application, effect level, manual action category, context awareness capability, collaboration mode and interaction functions. The technology-related dimension encompasses the aim of augmentation, proximity to reality, hardware, location, content positioning, time and scale.
Originality/value
The taxonomy provides a comprehensive framework for categorizing and understanding AR use cases in the AECO industry using the domain language. By providing a structured framework for exploring AR applications, the proposed taxonomy may not only facilitate standardized communication but also foster creativity when designing an AR use case.

Abstract
Purpose
Today social media capabilities have enabled businesses and enterprises to more collaboration, engagement and co-creation with their customers. So the current paper expands on this notion. The aim of this study is a bibliometric analysis to examine the trends of publications in the field of co-creation based on social media.
Design/methodology/approach
To data collection of quantitative analysis, Scopus database was selected and the collected data were analyzed using Bibliometrix-package. The Web of Science also was selected to retrieve highly cited and hot papers for qualitative part of analysis besides top 10 Scopus highest citation per year documents on June 6, 2020.
Findings
The results indicate insights into research trends pertaining to social media-based co-creation, as follows: starting jump to the publications occurred in this researches from the year 2008 and the growth trend is progressing in recent years; the stressful points are “co-design,” “co-creation” and “value co-creation” and concepts such as “open innovation,” “co-innovation” and “co-new product design” are new topics that guide future direction; the USA and UK are leaders in number of multiple and single publications; the most active and top journals that are better suited to achieving a high citation rate per year for a related paper were introduced. In addition, the top documents and highly cited papers were qualitatively analyzed on the basis of times cited per year.
Research limitations/implications
The current study is not free of limitations. The database was limited to only Scopus. So the patterns and trends generated in the study may not be generalized to all social media-based co-creation research. Of course, the authors did not intend to ignore other contributions. It is mainly because of the number of documents retrieved from Scopus database and the coverage, Scopus was selected. Moreover, other types of research techniques such as correspondence analysis can be incorporated to generate additional meaningful insight.
Originality/value
In this time of social media and user-generated content portals, co-creation through social media has become quite popular. So the main innovation of this study is providing a visual presentation of the trends and patterns in the evaluation of social media-based co-creation from the first document about the research area published till 2020. The results of this paper can shed light on the factors that strengthen the contribution of studies in a research area. Generally, the bibliometric items the authors analyzed essentially show the entire field picture and guide researchers toward understanding future trends to produce impactful studies.

Abstract
Purpose
Dietary components have been mentioned as modifiable risk factors in the development of gallstone disease (GSD), but it has been less addressed. The present study aimed to investigate the potential association between different types of dietary carbohydrate and the risk of gallstone.
Design/methodology/approach
In this case-control study 189 patients diagnosed with GSD as a case group and 342 people as a control group were enrolled. Dietary intake of the participants was collected through a 168-item semi-quantitative food frequency questionnaire. Total intakes of calories, macronutrients and different types of carbohydrate were estimated. Crude and multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between carbohydrate intake and GSD.
Findings
Patients with gallstone consumed significantly more fructose and sucrose and less fiber. After fully adjustment, the logistic regression indicated significant association between GSD with dietary intake of total carbohydrate (OR = 1.65, 95% CI: 1.1–2.4, p = 0.009), sugar (OR = 1.23, 95% CI: 0.8–1.7, p = 0.014), fructose (OR = 2.5, 95% CI: 1.7–3.9, p < 0.001), glucose (OR = 1.9, 95% CI: 1.3–2.9, p = 0.002) and sucrose (OR = 1.37, 95% CI: 0.9–1.6, p = 0.042). Also, increasing intakes of lactose, galactose and maltose were associated with a decrease in the risk of GSD, but not statistically significant, although lactose was close to significance (OR = 0.71, 95% CI: 0.48–1, p = 0.051).
Originality/value
There is a positive and significant relationship between total carbohydrate, sugar, fructose, glucose and sucrose intake and the occurrence of gallstone.

Abstract
Purpose
Diet is recognized as a possible potential factor in migraine pathogenesis. Limited evidence exists on the effect of diet on pediatric migraine, so this paper aims to investigate the association between fruit and vegetable consumption and odds of migraine in children.
Design/methodology/approach
The authors conducted a case-control study in tertiary Sina hospital, Tehran, Iran. A hundred children with migraine as case group and 190 sex-matched healthy controls were included in this study. Definite diagnosis of migraine was based on 2018 international classification of headache disorder 3 (ICHD3) criteria. Demographic and anthropometric characteristics were collected. Common dietary intake of participants was obtained using a validated semi-quantitative food frequency questionnaire.
Findings
Children in the migraine group had significantly higher BMI and age compared with the control group (p-value = <0.01). After adjustment for age, gender, BMI and total energy intake, a significant association between higher intake of vegetables in second tertile (OR: 0.47; CI: 0.24-0.92), fruits in third tertile (OR: 0.31; CI:0.14-0.69) and fiber in fourth quartile (OR:0.28; CI:0.095-0.85) was obtained. Controlling for all confounders in Model 3, the odds of migraine, decreased by 50 per cent and 70 per cent as the consumption of vegetables and fruits increased, in the second tertile of vegetables (p-value = 0.04) and the third tertile of fruits (p-value = <0.01).
Originality/value
The findings confirm a plausible protective role of dietary fruits and vegetables against the risk of migraine in children, which can be attributed to the probable effect of dietary fiber.

Abstract
Purpose
While several studies have reported a relationship between chronic daily headache (CDH) and different dietary patterns, no study has investigated the association between CDH and the dietary inflammatory index (DII). This study aims to hypothesize that a higher DII score (proinflammatory diets) is associated with higher odds of CDH.
Design/methodology/approach
This cross-sectional study was performed using the baseline data of the Dena PERSIAN cohort study, including demographic information, body mass index, medical history, laboratory tests, sleep duration and blood pressure. The DII was computed based on the data collected by a valid 113-item food frequency questionnaire and a 127-item indigenous food questionnaire. The association between CDH and DII score was analyzed by simple and multiple logistic regression.
Findings
Out of 3,626 people included in the study, 23.1% had CDH. The median DII was −0.08 (interquartile range = 0.18). People in the third and fourth quartiles of DII (proinflammatory diet) had a 20% (odds ratio: 0.80; 95% confidence interval: 0.65–1) and a 25% (odds ratio: 0.75; 95% confidence interval: 0.61–0.94) lower chance of having CHD than those in the first quartile, respectively. After adjustment for confounding variables, this association did not remain statistically significant (p > 0.05).
Originality/value
Although the analysis conducted without adjustment for medical history showed a significant association between proinflammatory diet and reduced CDH, considering the diverse etiology of different types of headaches and the paucity of studies in this area, further studies are needed to investigate the DII score of patients by the type of headache, its severity and duration.

Abstract
Purpose
The present study was designed with the aim of investigating the association between different dietary fatty acids and the risk of Gallstone disease (GSD).
Design/methodology/approach
The authors conducted a hospital-based, case-control study on 189 newly diagnosed GSD patients and 342 controls. Total fat and individual fatty acids, including monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA) and saturated fatty acids (SFA) were assessed.
Findings
Increased risk of GSD was observed in the highest tertile of total dietary fat (OR = 1.6, CI 95%: 1.09–2.8, p = 0.002) in the fully adjusted model. Comparing the highest intake with the first tertile, showed that intake of PUFA was significantly associated with a decrease in the risk of GSD (OR = 0.87, CI 95%: 0.5–1.5, p = 0.001), and intake of SFA (OR = 1.3, CI 95%: 1.07–2.2, p = 0.001) was associated with an increase in the risk of gallstones.
Originality/value
In this study, for the first time, we explored the role of dietary fatty acids in the development of GSD, including PUFA, MUFA and SFA. Their results could help elucidate the association between fatty acids and GSD more precisely and may be beneficial in prevention and treatment of cholelithiasis.

Abstract
Purpose
Transnational entrepreneurship can be considered a new stream of research where migrant entrepreneurship and international business research fields intersect. The purpose of this paper is to offer a theoretical framework to address the following research question: How do transnational entrepreneurs (TEs) develop their competitive advantage to succeed in a global market?
Design/methodology/approach
Based on the strategic entrepreneurship approach and dynamic capability perspective, this paper suggests a theoretical framework to extend the understanding on how TEs may develop their competitive advantage to succeed in a global market.
Findings
The suggested theoretical framework exhibits how the social ties of TEs affects their firm performance through the mediating effect of a bundle of two organizational processes (opportunity sensing and opportunity seizing) and the moderating effect of institutional distance between countries of origin and residence.
Practical implications
TEs should not solely focus on their ethnic social ties. That is why this paper suggests that ethnic ties in the country of origin and the country of residence (COR) may lead to higher firm performance only if systematically used alongside nonethnic ties in the COR. Furthermore, it is crucial for TEs to understand the importance of dynamic capabilities in developing and sustaining their competitive advantage.
Originality/value
Based on the strategic entrepreneurship approach, this paper suggests a social tie-based model of the dynamic capability to address the theoretical void in the transnational entrepreneurship literature. The linkage between social tie and performance which has been in a black box is examined in terms of how strong and weak social ties may affect different underlying processes of TEs’ dynamic capabilities differently. In contrast to the common conceptualization of institutional distance as a negative moderator in international business literature, institutional distance is theorized as a positive moderator in the suggested theoretical model of transnational entrepreneurship.

Abstract
Purpose
Education is a human right and access to high quality education is key to sustainable socioeconomic development. Improving the quality of higher education institutes is essential for generating the productive human resources. Assessing the quality of higher education from the students’ perspective can be considered a crucial factor in the monitoring of service quality in universities. The purpose of this paper is to evaluate the quality of educational services in a higher education institute, the Kermanshah University of Medical Sciences (KUMS), in the west of Iran.
Design/methodology/approach
A multistage sampling method was used to select 346 students from the KUMS, who were enrolled in the second semester of the academic year 2015-2016. The SERVQUAL questionnaire was used to gather data on students’ perceptions and their expectations about the quality of educational services. The authors used a statistical significance level of 0.05 to examine the gap between the students’ expectations and their perceptions of service quality in five dimensions, namely tangibles, responsiveness, reliability, empathy and assurance.
Findings
The results showed that there was a negative service quality gap in all five dimensions. The overall mean score of students’ expectations and their perceptions was 3.19±0.44 and 2.4±0.45, respectively. The score gap between the overall mean score of perceptions and expectations of students was −0.79, which was statistically significant (p<0.0001). The highest and lowest quality gaps were related to the assurance (−0.84) and tangible (−0.70) dimensions, respectively.
Originality/value
The study indicated that the quality of educational services provided in the KUMS did not meet students’ expectations in five dimensions of service quality. Thus, it warrants further investigations to determine how to improve the quality of educational services in higher education institutes such as the KUMS.

Abstract
Purpose
The purpose of this study is to investigate the relationship between dietary total antioxidant capacity (DTAC) and the dietary inflammatory index (DII) with inflammatory status in children recently diagnosed with Acute Lymphoblastic Leukemia (ALL). As the relationship between diet quality scores and inflammation remains uncertain in this population, the authors carried out a hospital-based cross-sectional study.
Design/methodology/approach
The study used a cross-sectional design involving 54 children recently diagnosed with ALL. Dietary data was collected using a 147-item semi-quantitative food frequency questionnaire developed for the Tehran Lipid and Glucose Study. Inflammatory status was evaluated using various indicators like C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Glasgow prognostic score (GPS) and Complete blood count-based inflammatory score.
Findings
The authors found no significant relationship between DII with inflammatory indices and length of hospitalization in patients. However, a significant inverse relationship was observed between the antioxidant indices ferric-reducing ability of plasma, total reactive antioxidant potential and Trolox equivalent antioxidant capacity with the inflammatory index MLR, respectively (ß: −0.19, p = 0.001), (ß: −0.42, p = 0.02), (ß: −0.53, p = 0.005). Also, a significant inverse relationship between FRAP and CRP was observed in the crude model (ß: −0.13, p = 0.05). FRAP was also inversely correlated with GPS and PLR, respectively (ß: −0.08, p = 0.02), (ß: −0.26, p = 0.03). No additional significant links were discovered between food scores and the outcomes studied.
Originality/value
This study found no link between DII with inflammatory markers or hospitalization duration in children with ALL. However, the authors did observe a noteworthy inverse relationship between DTAC and certain inflammatory markers like MLR. To achieve more dependable findings, further research in this area is necessary.

Abstract
Purpose
The purpose of this study is to carry out the demographic evaluation and analysis of the entrepreneurial orientation of librarians in Iranian public libraries using the Lumpkin and Dess model.
Design/methodology/approach
In this study, a structured questionnaire of entrepreneurial orientation was used. The research population consisted of 5,000 librarians of Iranian public libraries who were selected using Krejcie and Morgan table (95% confidence level and p-value of 5%) and stratified the random sampling method. A total of 365 individuals were selected as the study sample. Data were analyzed by SPSS software using descriptive statistics (frequency, percent, mean, standard deviation and standard error mean) as well as inferential statistics (Pearson correlation, one-sample t-test, independent samples t-test and ANOVA.
Findings
The results showed that the mean level of entrepreneurial orientation of librarians was 2.92 with an average level (µ = 3). Librarians were at an average level (µ = 3) in terms of components of innovativeness (2.98), risk-taking (2.93) and proactiveness (3.02). The status of the autonomy component (2.53) was at an undesirable level (3 < µ), and only the competitive aggressiveness status (3.12) was at the desirable level (3 < µ). The analysis of the librarian’s entrepreneurial orientation based on demographic characteristics indicated that the male librarian’s entrepreneurial orientation was higher than the female librarian’s (p-value = 0.039). Meantime, librarians with library and information science degrees have less entrepreneurial orientation than the librarians with other (non-librarian and information science) degrees (p-value = 0.01). Also, the higher the librarian’s degree, the lower their entrepreneurial orientation will be (p-value = 0.000). In addition, there was no significant relationship between librarians’ age (p-value = 0.14), marital status (p-value = 0.15) or work experience (p-value = 0.388) and their entrepreneurial orientation.
Practical implications
Entrepreneurial orientation is one of the significant concepts in entrepreneurship of organizations. Accordingly, studying the concept of entrepreneurial orientation and formulating an appropriate strategy is of great importance in improving the performance of libraries because libraries can be more useful and appealing to library members by enhancing the entrepreneurial orientation of librarians, delivering new, unique and tailor-made services to users’ needs.
Originality/value
Not much research has been carried out on entrepreneurship in library and information sciences. To the best of the authors’ knowledge, this is the first study to examine the entrepreneurial orientation of librarians based on their demographic characteristics.
