Given that a prerequisite for COVID-19 transmission is the interaction between individuals, it is reasonable to suspect that transportation networks may have contributed to the spread of COVID-19. This study uses the air transportation network to quantify the risk of COVID-19 spread in the United States. The proposed model is applied at the county level and identifies the risk of importing COVID-19-infected passengers into a given county. We also undertake an examination of the factors influencing the spread of COVID-19 in relation to air travel. Utilizing an extensive dataset encompassing various socioeconomic, demographic, and healthcare-related variables, our results indicate a positive relationship between these factors and the relative risk of COVID-19 spread, highlighting the pronounced impact of population density, air travel volume, and larger household sizes on increasing travel-related risk. Conversely, greater healthcare capacity, particularly in terms of hospital and intensive care unit (ICU) beds, is associated with reduced risk. We provide estimates of expected relative risk for each county and a ranking that can be useful for informing public health policies to stem the spread of the virus by devoting resources such as screening and enhanced travel protocols to airports located in at-risk counties.

Malaysian rice wines (tapai) manufactured in small-scale industries are usually formulated based on personal experiences under minimally controlled conditions for generations, especially in Sabah, one of the East Malaysian states. However, the quality and safety of rice wines were receiving increased attention to ensure better quality control, particularly those produced on an industrial scale. Therefore, this research aims to determine the fermentation dynamics and consumers’ acceptance of Malaysian rice wines produced using different sasad (a local term for starter culture from Sabah).

The physicochemical [total soluble solids (TSS), alcohol content, total titratable acidity (TTA) and pH] and microbiological [total yeast and mould count (TYMC) and total lactic acid bacteria (LAB) count] changes in Malaysian rice wines were determined to better understand the fermentation process for future process optimisation. Additionally, sensory evaluations were conducted to determine the consumers’ preferences for the rice wines.

The overall fermentation dynamics of rice wines exhibited similar trends with slight variations between the samples, demonstrating the effect of microbial compositions of sasad on the quality of final rice wines. Additionally, consumer acceptance tests showed that rice wines with darker shades of yellow and a stronger alcoholic aroma were preferable.

This is the first research that provides important insights into both the fermentation dynamics and consumers’ acceptance of Malaysian traditional rice wines, enriching the rice wine literature from the academic perspective and contributing to the production of safe and high-quality rice wines.

Buildability assessment is an important tool used in improving buildability of building designs. Its practice has positive impact on construction project such as cost-saving, material waste reduction, labour-saving technologies, increase in efficiency, saving wasteful efforts and quality improvement as well as cost-effective methods of site construction and future maintenance. However, there are several factors hindering building construction industry to implement buildability assessment. In addition, there are few studies that described the factors impeding the implementation of buildability assessment in construction industry. This study aims to determine the factors impeding buildability assessment implementation in the Nigerian building construction industry

Quantitative research method was adopted for the study. Questionnaires were administered to purposively selected group of architects, engineers, builders and quantity surveyors. A total of 368 questionnaires were distributed among the sampled participants, out of which a total of 219 representing 60% were sufficiently filled and returned. Data elicited were analysed using inferential and descriptive statistics.

The results revealed that “poor co-ordination amongst different design disciplines”, “lack of buildability assessment awareness”, “design review pattern where construction personnel (builders) are invited to assess the building production information”, “unwillingness to invest extra money and effort during the early stage of project” and “designers value aesthetics and functionalities more than buildability in their designs” are the topmost five factors impeding buildability assessment implementation in the Nigerian construction industry.

This study highlights factors impeding the implementation of buildability assessment in construction industry. An understanding of these factors can help stakeholders in the construction industry facilitate the development of strategies required to mitigate the factors impeding buildability assessment implementation in the sector.

Organizational commitment could influence nurses’ turnover intention, but we know little about how effort recognition may enhance all three aspects of nurses’ organizational commitment and consequently reduce their turnover intention. This study adopts the self-affirmation theory to examine how the number of effort recognitions received by a nurse may impact the normative, continuance and affective aspects of their organizational commitment and their turnover intention.

We collected two-wave data from the survey responses of 481 nurses in a large medical center in Taiwan between June and August, 2017 and between January and February, 2018 as well as counting the number of times their efforts were recognized as excellent by using patient/family performance appraisal forms in 2016. Bivariate correlation was used to test the hypotheses.

We found that effort recognition is positively associated with nurses’ normative organizational commitment but not with their continuance or affective commitment. The three aspects of organizational commitment are negatively associated with turnover intention.

Nurse managers who hope to reduce nurses’ turnover intention could consider adequately recognizing nurses’ outstanding performance.

The present study is the first to employ the self-affirmation theory to examine the impact of effort recognition on the three aspects of organizational commitment and turnover intention.

Augmented reality (AR) is an advanced version of the dynamic physical space that is perceived and received via visual, audio, digital and other sensory stimuli. The capabilities of virtual technologies change the field of university and education considerably. The necessity of using virtual technologies in the education field was revealed more in unforeseen disasters such as the COVID-19 pandemic. The adoption of a technology by its users is an important factor in the successful implementation of the technology. The present study evaluates several factors affecting the adoption of AR technology in the realm of tertiary education.

This study is applied in nature, and the necessary data were gathered through a survey questionnaire. The opinions of 621 students were investigated using a simple random sampling method. The multinomial logit test was used in this research.

It was found that individual and social factors such as age, education level, major and economic characteristics such as one’s income in a month, expenses of a person in a month, the level of access to high-speed internet and access to a laptop or smartphone are effective in AR technology adoption in the field of academic education.

The theoretical contribution of this study is to identify the key factors that influence the adoption of AR technology and develop a model specifically applicable to the educational field. The results of this research can be used by university managers and educational policymakers for the efficient and effective use of this technology.

Social media has emerged as a prominent platform for marketers and brands to disseminate brand-related information. This study aims to investigate the impact of color congruence between themes and background on marketing effectiveness, focusing specifically on Instagram.

A laboratory experiment was conducted to investigate how color congruence between themes and background in brand posts influences flow and aesthetic experience, subsequently affecting marketing communication parameters such as brand attitude, visit intention, and eWOM on Instagram. Moreover, Adidas Originals was selected as the focal brand, and blue and white color was chosen as the primary color palette for the experimental material.

This study demonstrates that color congruence, regardless of brand layout or post, significantly influences flow and aesthetic experience, subsequently affecting marketing effectiveness.

This study contributes to the theoretical understanding of congruence theory and social media marketing, providing valuable insights for brands to enhance their communication through photographs and effectively manage their official Instagram accounts.

This study aims to build a comprehensive model for developing higher education institutes (HEIs) brand equity by examining the impact of HEIs intangible resources, brand management aspects, attachment strength and student’s contemporary citizenship behavior (CCB).

Data were gathered through a self-administered questionnaire from Indian students and alumni (n = 703). The study examines the proposed comprehensive model through serial and multiple mediation analysis.

The study unfolded “service quality? brand image? attachment strength? word-of-mouth? brand equity” as the most significant path to develop HEI’s brand equity.

This study pioneers an empirically validated mechanism for developing brand equity in HEIs, addressing gaps identified by previous studies and offering a theoretical framework that elucidates how HEIs can leverage intangible resources through strategic brand management to foster attachment and influence positive student behaviors, thereby contributing to the development of HEI brand equity.

HEIs need to understand that relying solely on tangible aspects leads to short-lived effects. To maintain a lasting competitive advantage, HEIs should focus on crafting a rich historical narrative, retaining talented faculty and staff and earning respect from the public to build a lasting reputation.

This study develops the mechanism for developing brand equity of HEIs using its valuable, rare and inimitable intangible resources. Along with the introduction of novel constructs like competence, heritage and word-of-mouth to existing study, the proposed conceptual model is premised on the theory of self-congruence, social-exchange theory and CCB.

This study aims to improve the acceleration in the additive manufacturing (AM) process. AM tools, such as extrusion heads, jets, electric arcs, lasers and electron beams (EB), experience negligible forces. However, their speeds are limited by the positioning systems. In addition, a thin tool must travel several kilometers in tiny motions with several turns while realizing the AM part. Hence, acceleration is a more significant limiting factor than the velocity or precision for all except EB.

The sawtooth (ST) scanning strategy presented in this paper minimizes the time by combining three motion features: zigzag scan, 45º or 135º rotation for successive layers in G00 to avoid the CNC interpolation, and modifying these movements along 45º or 135º into sawtooth to halve the turns.

Sawtooth effectiveness is tested using an in-house developed Sand AM (SaAM) apparatus based on the laser–powder bed fusion AM technique. For a simple rectangle layer, the sawtooth achieved a path length reduction of 0.19%–1.49% and reduced the overall time by 3.508–4.889 times, proving that sawtooth uses increased acceleration more effectively than the other three scans. The complex layer study reduced calculated time by 69.80%–139.96% and manufacturing time by 47.35%–86.85%. Sawtooth samples also exhibited less dimensional variation (0.88%) than zigzag 45° (12.94%) along the build direction.

Sawtooth is limited to flying optics AM process.

Development of scanning strategy for flying optics AM process to reduce the warpage by improving the acceleration.

The objective of this research was to test the effect of information and communication technology (ICT) resources, library facilities, teacher lecturing skills and physical classroom environment on student satisfaction and university image. This paper also sought to contribute to the existing body of knowledge by confirming the role of student satisfaction as a mediator among the stated factors and university image.

Data were collected from 314 students at higher education institutions (HEIs) in the United Arab Emirates (UAE) using a survey instrument. Throughout the data analysis stage, the partial least squares structural equation modeling (PLS-SEM) was employed in order to validate the research instrument and test the hypotheses.

The findings verified that teacher lecturing skills and ICT resources have a positive effect on both student satisfaction and university image. Moreover, the study revealed that the library facilities and physical classroom environment positively affect both student satisfaction and university image. Lastly, the analysis showed that student satisfaction mediates the link between the stated factors and university image.

This paper adds to the published literature by investigating the direct and indirect effects of teacher lecturing skills, ICT resources, physical classroom environment and library facilities on university image via student satisfaction at HEIs in the UAE. This study is the first to integrate all of these factors into a single research model.

Against social cognitive and social exchange theories, this research paper aims to investigate the significance and interaction between perceived knowledge, involvement, trust and brand community engagement in brand communities (BC).

BC participants (n = 503) completed a cross-sectional survey for this research. Analysis was performed using PLS-SEM via SmartPLS (v. 4.1.0.2) and the novel Necessary Condition Analysis (NCA).

An integrative KITE model with positive and significant relationships of key BC constructs was established. The perceived BC knowledge influenced involvement and engagement. Furthermore, the constructs of involvement and trust were discovered to have a positive and significant impact on engagement, with trust having a substantial effect on BC engagement. The indirect effects of the trust construct via the BC knowledge and BC involvement constructs were also significant.

This research advances the existing conceptual approaches by introducing knowledge as the key BC constructs. The study illustrates that members’ knowledge about a BC facilitates their involvement in the BCs. The vital role of trust is revealed in the KITE model, as it is significantly related to BC knowledge, BC involvement and BC engagement with at least medium to large effect sizes. Notably, the role of trust is enhanced as it is the only necessary must-have (instead of “should-have”) condition to achieve high levels of BC engagement. Furthermore, the KITE model provides insights for marketers to develop a valuable BC.
