Abstract
This study explores whether metacognitive strategy training can influence the lexical knowledge of L2 learners of the present study, and what they think about the use of metacognitive strategies in language learning classes. To do so, a 50-item multiple-choice vocabulary test, developed by the researchers based upon Nation’s (1990) levels of language proficiency, was employed to measure the learners’ vocabulary knowledge progress during the period of instruction. The instruction received by the experimental group was based on the Cognitive Academic Language Learning Approach (CALLA) Model, developed and validated by Chamot and O’Malley (1994). The findings revealed that the experimental group outperformed the control group in their endeavors for comprehending and producing vocabulary. This may be attributed to the fact that after this intervention, participants have developed their metacognitive awareness and their thinking skills. The study concludes with pedagogical implications and highlights avenues for future research.

Abstract
Purpose
The aim of this study is to optimize the electrospinning parameters used in the production process of polyvinyl chloride (PVC) nanofibers.
Design/methodology/approach
The response surface methodology (RSM) was used to determine the experimental design. The 30 nanofiber prototypes candidates were electrospun using a needle-based electrospinning machine. PVC polymer, N-dimethyl formamide and tetrahydrofuran solvents were used to prepare the electrospinning solution.
Findings
The electrospun nanofibers had a mean diameter of 386 ± 136.57 nm, in the range of 200−412 nm. The mean porosity was 31.60 ± 6.37% in the range of 15.33−41.53%. The webs made from electrospun nanofibers had a mean pressure loss of 194.23 ± 47.7 pa in the range of 124−300 pa. The highest statistically significant correlation was observed between solution concentration and nanofiber diameter (r = 0.756, p < 0.05).
Originality/value
The optimal electrospinning parameters were determined to be: a solution concentration of 11 weight percent, a voltage of 16.5 kV, a needle-collector distance of 13.5 cm and an electrospinning duration of 4 h.

Abstract
Purpose
Dietary intake is a modifiable risk factor for metabolic syndrome (MetS). Therefore, this study aims to evaluate the association between the Healthy Eating Index-2015 (HEI-2015) and MetS.
Design/methodology/approach
MetS was diagnosed among 2,326 adults. Dietary intake was assessed by a validated food frequency questionnaire. The HEI-2015 was administered to assess the diet qualities. Multivariate logistic regression was also used to evaluate the relationship of HEI-2015 with MetS and its components.
Findings
The odds of MetS was lower in women who were in the third quintile of HEI-2015 compared with those in the first quintile after adjusting for age and energy intake (OR: 0.62, CI: 0.41 to 0.93). In addition, moderate adherence to HEI-2015 reduced the odds of high fasting blood glucose levels in both men and women (OR men: 0.30, CI: 0.11 to 0.85 OR women: 0.34, CI: 0.14 to 0.79). However, these relations were not linear. Adherence to HEI-2015 had no significant relationship with the prevalence of MetS and its components in the whole population.
Originality/value
A significant relationship was observed between moderate adherence to HEI-2015 and fasting blood glucose in both men and women. Moreover, moderate adherence to this dietary pattern decreased the prevalence of MetS in women.

Abstract
Purpose
Domestic refrigerators could be considered as one of the major potential sources of food-borne diseases, in addition limited data are available regarding the level of contamination of domestic refrigerators in Iran. The purpose of this paper is to detect some of bacterial contamination in domestic refrigerators.
Design/methodology/approach
In total, 104 households were randomly selected from ten health centers in five areas of Tehran, Iran. Visual inspection and temperature evaluation of the households’ refrigerators were done. In addition, the refrigerators were swabbed and analyzed for contaminants using polymerase chain reaction (PCR) method. DNA was isolated and purified by the proposed standard protocol.
Findings
Screening of the domestic refrigerators by PCR method showed that 51.7 percent of the samples were positive for pathogens as follows: L. monocytogenes 41.6 percent, S. aureus 5.5 percent, Salmonella spp 4.6 percent, and E. coli O157:H7 0 percent; consequently, none of mentioned pathogens were detected in 48.3 percent of the refrigerators. Results of the visual inspection indicated that 57 percent of the refrigerators were on desirable, 36.5 percent were acceptable, and 7 percent were weak conditions. Most of the refrigerators about 44 percent had desirable temperatures. There were no significant correlations between the visual inspection scores, temperature and frequency of isolation of specific pathogens in the domestic refrigerators. A significant correlation was observed between contamination and education of parents (p < 0.05).
Originality/value
Determination of the bacterial contamination and evaluating the temperature of domestic refrigerators in Iran can be considered as a novel approach of current study. These findings could be employed in designing and implementing appropriate educational interventions to promote food safety and diminish the risk of food-borne illnesses. Also, obtained results might be applied as introduction for further investigations.

Abstract
Purpose
This study aims to observe the coloring efficacy of coffee-based natural brown colorant for cotton dyeing under microwave (MW) treatment.
Design/methodology/approach
The colorant extracted in particular (neutral and acidic) media was stimulated by MW treatment up to 6 min. Dyeing variables were optimized and 2–10 g/100 mL of sustainable anchors (mordants) have been used to get colorfast shades.
Findings
It has been found that un-irradiated acidic extract (RE) containing 5% of table salt at 80 °C for 50 min has given high color yield onto MW-irradiated cotton fabric (RC = 2 min). The utilization of 2% of Fe, 10% of tannic acid and 10% of sodium potassium tartrate before bio-coloration, whereas 4% of Fe, 10% of tannic acid and 6% of sodium potassium tartrate after bio-coloration has given good color characteristics. In comparison the application of 6% of pomegranate and turmeric extracts before bio-coloration and 6% of pomegranate and 10% of turmeric extracts after bio-coloration have given good color characteristics. New bio-mordants can be added to get more new colorfast shades.
Research limitations/implications
There is no research limitation for this work. New bio-mordants can be added to get more new colorfast shades.
Practical implications
This work has practical application for artisans, textile industry and handicrafts. It is concluded that colorant from coffee beans can be possible alternative of synthetic brown dyes and inclusion of MW rays for extraction and plant molecules as shade developers can make process more green.
Social implications
Socially, it has good impact on eco-system and global community because the effluent load is not carcinogenic in nature.
Originality/value
The work is original and contains value-added product for textiles and other allied fields.

Abstract
Purpose
This study aims to examine the association between Iranian auditors' narcissism and the auditors' professional skepticism.
Design/methodology/approach
The authors' sample is comprised of 355 professional auditors working in the private and public sectors in Iranian firms in 2022. The authors use cross-sectional multivariate regression as the main methodology, along with the structural equation modeling (SEM) technique.
Findings
The authors find that a higher level of narcissism leads to a greater level of professional skepticism among auditors, which ultimately can enhance the quality of the audit process. The results provided via the robustness tests also supported this finding.
Originality/value
The authors' findings further the understanding of the role of narcissistic personality traits in improving professional skepticism among auditors of an Islamic and emerging country. In addition, audit firms and audit partners can also consider the findings of this study and enhance the effectiveness of audit processes by assigning appropriate employees with certain personalities to specific tasks.

Abstract
Purpose
This study aims to investigate the association of vitamin D intake and the risk of depression, anxiety and stress among Tehranian female adolescents.
Design/methodology/approach
This cross-sectional analysis included 263 participants. A valid and reliable food frequency questionnaire was used to determine dietary intake of vitamin D. Depression, anxiety and stress scores were characterized by Depression Anxiety Stress Score-21 questionnaire. Multivariable logistic regression was used to estimate the odds ratio (OR) for the occurrence of depression, anxiety and stress according to the tertiles of vitamin D intake.
Findings
The mean ± standard deviation age and body mass index (BMI) of participants were 16.2 ± 1.0 years and 22.2 ± 4.1 kg/m2, respectively. Mean score of depression, anxiety and stress of participants were 9.8 (low-grade depression), 8.4 (low-grade anxiety) and 14.0 (borderline for stress), respectively. In the final model, after adjustment for age, BMI, physical activity, mother/father’s education level, dietary fiber and total energy intake, the OR for depression in the highest compared to the lowest tertile of vitamin D intake was 0.53 (95% confidence interval [CI], 0.24–0.98) (p for trend: 0.040). Moreover, based on the fully adjusted model, participants in the highest tertile of vitamin D intake had lower odds of stress (OR: 0.49; 95% CI: 0.23–0.93), in comparison to those in the lowest one (p for trend: 0.021).
Originality/value
To the best of the authors’ knowledge, this is the first study to assess the association of vitamin D intake and risk of psychological disorders, including depression, stress and anxiety in Middle East and North Africa region’s female adolescents.

Abstract
Purpose
The purpose of this paper is to look into millennials’ acceptance of Qard al-hasan using the Islamic theory of consumer behaviour (iTCB) in Malaysia.
Design/methodology/approach
For this study, convenience sampling was used and 203 usable questionnaires were received from the respondents who are millennials and university students. The questionnaire link was distributed via social media platforms to the millennials.
Findings
The findings of this study reveal that there exists a strong and positive relationship between the role of iman and Maqasid consumer index in determining the millennial acceptance of Qard al-hasan. On the contrary, Islamic altruism does not turn out to be the factor of Qard al-hasan acceptance. Resultantly, these results suggest that millennials in Malaysia accept Qard al-hasan and based on those educational institutions may consider offering zero-interest benevolent loans to alleviate the financial burden of unprivileged students.
Research limitations/implications
Although this study provides positive results, a minimum of two research constraints may direct future efforts in this area. This study initially focuses on a specific ecosystem of Islamic financial products in Malaysia, with a particular emphasis on Qard al-hasan. As a result, subsequent research ought to strive to encompass a larger perspective on Qard al-hasan. Secondly, this research uses a theory that is still in the applicability phase, which has led to some productive discussions for further improvements.
Originality/value
To the best of the authors’ knowledge, this work is one of the few studies conducted on an empirical basis using the iTCB in the milieu of Qard al-hasan in Malaysia.
