Brief introduction on the importance and the need for plastic analysis methods were presented in the beginning section of this review. The plastic method for analysis was considered to be the more advanced method of analysis because of its ability to represent the true behaviour of the steel structures. Then in the following section, a literature analysis has been carried out on the previous investigations done on steel plates, steel beams and steel frames by other authors. The behaviour of them under different types of loading were presented and are under the investigation of innovative new analysis methods.

Structure member connections also have the potential for plastic failure. In this study, the authors have highlighted a few topics to be discussed. The three topics in this study are T-end plate connections to a square hollow section, semi-rigid connections and cold-formed steel storage racks with spine bracings using speed-lock connections. Connection is one of the important parts of a structure that ensures the integrity of the structure. Finally, in this technical paper, the authors introduce some topics related to seismic action. Application of the Theory of Plastic Mechanism Control in seismic design is studied in the beginning. At the end, its in-depth application for moment resisting frames-eccentrically braced frames dual systems is investigated.

When this study involves the design of a plastic structure, the design criteria must involve the ultimate load rather than the yield stress. As the steel behaves in the plastic range, it means the capacity of the steel has reached the ultimate load. Ultimate load design and load factor design are the methods in the range of plastic analysis. After the steel capacity has reached beyond the yield stress, it fulfills the requirement in this method. The plastic analysis method offers a consistent and logical approach to structural analysis. It provides an economical solution in terms of steel weight, as the sections designed using this method are smaller compared with elastic design methods.

The plastic method is the primary approach used in the analysis and design of statically indeterminate frame structures.

Although e-wallet adoption has grown in recent years, there are some countries like Peru with low penetration rates. Contrary to prior studies that focused on customers' adoption of e-wallets, this study focuses on merchants' adoption to fully understand the use of these services. Additionally, considering that e-wallets are two-sided markets with the co-existence of two distinct economic agents (customer and merchants) interacting through these platforms, this study is the first to assess the dynamics of inter-side benefits from the merchants' perspective. Finally, interoperability was also included to determine its role in countries where the interaction between different e-wallets is limited.

Based on two-sided markets and social cognitive theory, a model was proposed including merchants' perceived benefits associated with the use of e-wallets, for them and for their customers (inter-side). Additionally, technical issues such as interoperability were measured. Data were collected from nanostore owners in Lima in 2022. A structural equation modeling technique was used to determine the impact of both types of benefits and technical features on merchants' adoption of e-wallets. Finally, a polynomial regression with response surface methodology was used to assess the interaction of the benefits for both sides of the platform from the merchants' perspective.

The two-sided-market features of e-wallets were validated. From merchants' view, the use of these platforms is the result of balancing the benefits for them and for their customers, and the interaction between these two types of benefits varies according to the socio-economic level in which the nanostore operates. Additionally, interoperability was found to be important for merchants, so future policies should commit to achieve an ecosystem that facilitates the interoperability not only among e-wallets but also between e-wallets and third-party services. Finally, since service availability is also important for merchants, e-wallet providers should invest in improving their infrastructure's scalability.

Prior studies have mainly focused on the customer side of e-wallets, with little research about the adoption of digital payment methods by the merchant side. In addition, no study has focused on the effect of one of the sides of the platform on the other side (inter-side benefits) when adopting these services. Finally, the effect of interoperability across platforms has not been addressed in detail yet. This study aims to fill these gaps by proposing a framework to understand the adoption of these services by merchants in terms of inter-side benefits and technical issues.

The paper aims to examine the moderating role of both the perceived value and perceived trust in the relationship between the ease of use, perceived risk, perceived usefulness and quality of website and the Palestinian millennials’ behavioral intention toward online shopping.

A survey questionnaire was carried out targeting 357 Palestinian millennials. In total, 311 valid responses were processed and analyzed using PLS-SEM model fitting approach.

The findings demonstrate that the impact of ease of use, perceived usefulness and website quality on online shopping behavioral intention are reinforced by perceived value and perceived trust, while the effect of perceived risk is weakened. This implies that improving convenience and lowering non-monetary costs such as time and effort will enhance the customers’ perceived value and, as a result, their shopping behavioral intention. In addition, one of the most significant barriers to online shopping is a lack of trust. Therefore, once trust is established, shopping willingness rises, and vice versa.

As this study focused on consumers from a developing country, it neglected the cross-cultural issue; thus, future studies may have to make a comparison of other samples from various nations to gain a deeper understanding. Furthermore, this research focused on the ease of use, perceived risk, perceived usefulness and perceived quality of the website to predict the customer’s behavioral intention toward online shopping, which shows significant results, indicating that more research is needed to look at these independent variables as predictors of customers purchasing decision.

Online shopping is a critical topic that has significant impact on the business world. Investigating the moderating role of perceived trust and perceived value on Palestinian millennials’ online shopping behavioral intention during COVID-19 might give useful information for organizations developing policies and strategies to create direct sales using social media platforms. Furthermore, the findings might also be valuable for management studies and academics to better understand consumers’ intentions when it comes to commercial internet buying.

The empirical nature of this paper gives a thorough explanation of the phenomena of online shopping from a developing country. To the best of the authors’ knowledge, this is the first empirical study that examines the moderating effect of perceived trust and perceived value on Palestinian millennials’ online shopping behavioral intention during COVID-19.

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.

Online reviews are regarded as a source of information for decision-making because of the abundance and ready availability of information. Whereas, the sheer volume of online reviews makes it hard for consumers, especially the older adults who perceive more difficulties in reading reviews and obtaining information compared to younger adults, to locate the useful ones. The main objective of this study is to propose an effective method to locate valuable reviews of mobile phones for older adults. Besides, the authors also want to explore what characteristics of the technology older adults prefer. This will benefit both e-retailers and e-commerce platforms.

After collecting online reviews related to mobile phones designed for older adults from a popular Chinese e-commerce platform (JD Mall), topic modeling, term frequency-inverse document frequency (TF-IDF), and linguistic inquiry and word count (LIWC) methods were applied to extract latent topics and uncover potential dimensions that consumers frequently referred to in their reviews. According to consumers' attitudes towards different popular topics, seven machine learning models were employed to predict the usefulness and popularity of online reviews due to their excellent performance in prediction. To improve the performance, a weighted model based on the two best-performing models was built and evaluated.

Based on the TF-IDF, topic modeling, and LIWC methods, the authors find that older adults are more interested in the exterior, sound, and communication functions of mobile phones. Besides, the weighted model (Random Forest: Decision Tree = 2:1) is the best model for predicting the online review popularity, while random forest performs best in predicting the perceived usefulness of online reviews.

This study’s findings can help e-commerce platforms and merchants identify the needs of the targeted consumers, predict reviews that will get more attention, and provide some early responses to some questions.

The results propose that older adults pay more attention to the mobile phones' exterior, sound, and communication function, guiding future research. Besides, this paper also enriches the current studies related to making predictions based on the information contained in the online reviews.

This study aims to integrate and extend leading contemporary underpinning frameworks such as the Stimulus Organism Response (S-O-R) model, Technology Acceptance Model (TAM) and Unified Theory of Acceptance and Use of Technology (UTAUT) to assess the determinants of M-commerce usage during COVID-19 times. Besides direct effects, the study examines the mediating role of behavioral intention in affecting the relationship between a few external stimuli, internal states (of the organism) and M-commerce usage (the response). The study has also examined the moderating role of habitual behavior in the relationship between behavioral intention and M-commerce usage.

Data were gathered from 312 customers through an online survey using a structured questionnaire. PLS-based SEM, using Smart PLS 4.0, was employed to calibrate the measurement and structural models.

The study found that stimuli like social influence, perceived ease of use and perceived value substantially affected M-commerce usage. Behavioral intention has been found to mediate these cause-and-effect relationships partially or fully among the subject constructs. Additionally, a significant negative but weak moderating impact of habit (or habitual behavior) on the relationship between behavioral intentions and M-commerce usage has been corroborated.

Several studies have investigated the factors influencing the adoption and continued usage of M-commerce services while appealing to diverse theoretical frameworks. However, more research has yet to be expended to arrive at an integrated explanation grounded in these theoretical frameworks to examine the dynamics of M-commerce usage in tempestuous times like the COVID-19 outbreak. The most significant (counterintuitive) findings have been suppressing the effects of otherwise crucial elements like perceived security and habit in prompting M-commerce usage in the face of the socio-psychological pressures stemming from COVID-19 restrictions and consumers' lack of digital readiness. The study's outcomes offer several theoretical and practical implications for researchers, managers, practitioners, businesses and policymakers to develop effective strategies to mature M-commerce usage among the masses, especially during unusual times like COVID-19.

The main aim of this study is to examine the effect of virtual store atmospheric factors on impulsive purchasing in the metaverse context.

Grounded in purposive sampling, 451 individuals with previous metaverse experience were recruited to accomplish the objectives of this research. Next, to identify both linear and nonlinear relationships, the data were analyzed using partial least squares structural equation modeling (PLS-SEM) and artificial neural network (ANN) approaches.

The findings underscore the significance of the virtual store environment and online trust in shaping impulsive buying behaviors within the metaverse retailing setting. Theoretically, this study elucidates the impact of virtual store atmosphere and trust on impulsive buying within a metaverse retail setting.

From the findings of the study, because of the importance of virtual shop content, practitioners must address its role in impulse purchases via affective online trust. The study’s findings are likely to help retailers strategize and improve their virtual store presentations in the metaverse.

The discovery adds to the understanding of consumer behavior in the metaverse by probing the roles of virtual store atmosphere, online trust and impulsive buying.
