Semi-active suspension systems with electromagnetic dampers allow energy regeneration and the required control strategies are easier to implement than the active suspensions are. This paper aims to address the application of a tubular linear permanent magnet synchronous machine for a semi-active suspension system.

Classical rules of mechanics and electromagnetics were applied to describe a dynamic model combining vibration and electrical machines theories. A multifaceted MATLAB®/Simulink model was implemented to incorporate equations and simulate global performance. Experimental tests on an actual prototype were carried out to investigate displacement transmissibility of the passive case. In addition, simulation results were shown for the dissipative semi-active case.

The application of the developed model suggests convergent results. For the passive case, numerical and experimental outcomes validate the parameters and confirm system function and proposed methodology. MATLAB®/Simulink results for the semi-active case are consistent, showing an improvement on the displacement transmissibility. These agree with the initial conceptual thoughts.

The use of linear electromagnetic devices in suspension systems is not a novel idea. However, most published papers on this subject outline active solutions, neglect semi-active ones and focus on experimental studies. However, here a dynamic mechanical-electromagnetic coupled model for a semi-active suspension system is reported. This is in conjunction with a linear electromagnetic damper.

The aim of this study is to evaluate the implicit and explicit attitudes of Generation Z (Gen Z) individuals toward the experience of visiting and getting to know traditional or virtual museums.

Two studies were conducted. The first study assesses the implicit attitudes of Gen Z individuals through Implicit Association Tests (IAT) toward the experience of visiting traditional versus virtual museums. Considering the results of the study one, the second study proposes and validates a conceptual model through PLS-SEM approach about the explicit attitudes of this generation toward virtual museums.

In the first study, it was found that virtual museums are more successful at engaging and immersing participants than traditional museums for Gen Z. The second study emphasized the significance of meeting Gen Z expectations and ensuring effortless access to information in virtual experiences as this can lead to increased satisfaction and inspiration among this generation.

The originality of this study lies in its focus on Gen Z's attitudes toward virtual museums and the use of both implicit and explicit attitude measures to gain a comprehensive understanding of these attitudes. An interesting aspect emerges from the implicit attitudes displayed by Gen Z, indicating their preference for virtual museums as more captivating compared to traditional ones.

This study aims, first, to understand consumers’ perception of chefs as human brands (i.e. study one). Second, tests were run to assess the validity of a new conceptual model of the relationships between the factors of chef image, luxury restaurant image, both images’ congruity and consumers’ hedonic and novelty experiences and happiness and well-being (i.e. study two).

The first qualitative study involved using Leximancer software to analyse the data drawn from 43 interviews with luxury restaurant clients. In the second quantitative study, 993 valid survey questionnaires were collected, and the proposed model was tested using structural equation modelling.

The results reveal that consumers perceive chefs as human brands and the associated narratives include both performance- and popularity-based characteristics. The findings support the conclusion that individuals give great importance to chefs’ image and the congruence between chefs and their restaurant’s image. In addition, luxury restaurant image only affects novelty experiences, and both hedonic and novelty experiences have a positive effect on customers’ happiness and well-being.

This research focused on Portuguese luxury restaurants. The consumers’ happiness and well-being needs to be replaced by other outcomes to confirm if the model produces consistent results.

The results should help luxury restaurant managers understand more fully which pull factors are valued by their clients and which aspects contribute the most to their pleasure and welfare.

This study adds to the extant literature by exploring consumers’ perceptions of chefs as human brands and the role these chefs’ image play in customers’ luxury restaurant experiences and perceived happiness and well-being.

The present research had the objectives of proposing, testing and validating a theoretical model that includes ecological awareness, healthy consumption, consumer attitude and price awareness as determinants of the purchase intention of organic foods and analyzing the moderating effect of gender, educational level and income of families in the relationship between price awareness and purchase intention.

A survey research was implemented with 382 Brazilians who consume organic foods from a non-probabilistic sample for convenience. For data analysis, structural equation modeling was used to test the proposed theoretical model and its respective relationships.

The results showed that ecological awareness, healthy consumption, consumer attitude and price awareness are determinants of the purchase intention of organic foods 79.1% of the variance of purchase intention of organic foods could be explained by such determinants. Another relevant result is that gender and family income has a positive moderating effect on the relationship between price awareness and the intention to purchase organic food.

Environmental problems and their adverse impacts on humans have become an important issue to be analyzed by academics (researchers), governments and organizations, and their managers, especially when organic foods are considered.

This paper aims to investigate the effect of product price image (PPI) on perceived value (PV) and repurchase intention (RI) of Brazilian customers' craft beer. Moreover, this research also verifies the moderating effect of customer experience (CE) and price sensitivity.

The survey data analysis was performed using Smart-PLS 3.3.9 and Process 4.1 software with 329 customers.

The results show that PV is a full mediation variable in the relationship between PPI and RI. As a mediated moderation, lower CE and price sensitivity better explain the indirect effect of PPI on RI via PV.

Thus, managers may reinforce the PV of low price sensitivity and low CE. These customers learn about companies' prices compared with higher price-sensitive customers and higher CE that already PV.

The article discusses the implications of PV as a mediator, low price sensitivity and low CE as moderators for craft beer.

1. The world's most widely consumed alcoholic beverage, following water and tea, the third-most-popular drink on earth is beer;

2. Managers should create strategies to reinforce the PV and consequently the RI by offering PPI and benefits (PV) for customers with low experience and low-price sensitivity about craft beer;

3. Low customer experience and low-price sensitive's customers are learning about companies' prices compared to higher price sensitive, and higher customer experience that already PV, PL, PF, and PEs and NEs;

4. Small producers craft beer that connotated the product's high quality and benefits; the higher may be the level of RI and consumption from customers.

The purpose of this paper is to compare working conditions, experiences of discrimination and suspected cases of common mental disorders (CMDs) among Haitian and Brazilian migrant workers in the same production processes.

This cross-sectional, exploratory study was conducted using a nonprobabilistic convenience sample of Brazilian and Haitian migrant workers aged over 18 years from the capital of the Brazilian Midwest, evaluated from October 2018 to May 2019. Individual and face-to-face interviews were conducted using a structured questionnaire consisting of three instruments: health and work (questions of the Health and Work Survey: Inquérito Saúde e Trabalho), the experience of discrimination score and the self-reporting questionnaire.

In total, 165 workers were evaluated: 99 Haitians (58 from the service sector and 41 from the construction sector) and 66 Brazilians (37 from the service sector and 29 from the construction sector). Male workers of both nationalities were predominant. Deafening noise and dust or gas exposure were more prevalent among Brazilians than among Haitians. Chemical agents and radiation exposure have been reported more frequently among Haitians. Discrimination related to nationality or race was nine times more common among Haitians (10.1%) than among Brazilians (1.5%). Perceived discrimination at work was higher among Haitians (16.2%) than among Brazilians (3.0%). The prevalence of suspected CMDs among Haitians and Brazilians were 24.0% and 4.5%, respectively.

Despite the limitation regarding convenience sampling and the high number of Brazilians who refused to participate in the interviews, this paper brings contributions and recommendations. First, considering that comparisons in health outcomes between migrants and nonmigrant are challenging, this study sheds light on the knowledge of work-health relations between migrant populations and host populations.

This study’s results have attempted to show the importance of protecting health in the workplace as a right to be defended. In this regard, a matter of great concern is the recent loss of labor rights in Brazil and the Brazilian decision to leave the Migratory Pact, which aims to strengthen migrants’ rights, contributing to sustainable development

Also, work is identified as a powerful determinant of health and a place that should protect and promote health. There is an urgent need to monitor and proceed with workers’ health surveillance to grasp the impacts of work on migrant’s health, develop health-work indicators and trigger plans and programs in health services.

Haitians are at a disadvantage compared to Brazilians, mainly related to discrimination due to nationality and skin color. Experiences of discrimination and a higher prevalence of suspected cases of CMDs were observed among Haitian workers.

This study aims to check which scale of love brand developed by Carroll and Ahuvia (2006) or Mohammadian and Karimpour (2014) have better adhesion to the perception of Aspirin love brand, that is, a functional brand.

The conceptual models and associated hypotheses are tested with a sample of 321 consumers. Data were analyzed through a structural equation model.

The results demonstrate strong relationships between the three antecedents (brand engagement, confidence and overall attitude) and brand love and between brand love and its consequences (brand loyalty, positive word of mouth and brand purchase intention) in both scales.

The main limitation of the study relates to the sample, which is only of Portuguese consumers and does not match the main socio-demographic characteristics of the population. Therefore, the study should be seen as exploratory on the brand love in the case of functional brands.

The knowledge that a consumer can establish an emotional relationship with a functional brand, in a highly competitive sector as the pharmaceutical sector, in particular in drugs that are sold without a prescription, can help managers in defining their communication strategy appealing to the emotions and long-term involvement with the consumed.

Few studies about the background of the brand love and those that exist are linked to hedonic product categories and self-expressive brands. It is the first time that the brand love for a medicine is evaluated.

The purpose of this study was to reduce the ED of sweet preparations through calorie reduction by replacing sucrose, reducing fat, and increasing the amount of dietary fiber.

Sweet preparations were chosen to reduce ED and increase dietary fiber. Sucrose was replaced by two types of sweeteners, white flour was partially replaced by whole grain flour and fat was reduced. Preparations that had the desired characteristics underwent sensorial analysis to assess their acceptability, and rated by the affective test with hedonic scale. Preparations rated with 50 percent of grades greater than or equal to 7 were considered accepted. Analysis and calculations were performed using FIZZ software. The percentage change in ED was calculated as the difference between the ED of those ingredients replaced and/or reduced.

The preparations butter cookies, lemon pie topped with whipped cream and carrot cake with chocolate frosting were accepted by most of the tasters. It proved possible to reduce ED by approximately 4.0 kcal per gram and to increase the amount of total dietary fiber from 1.8 g/100 g to 3.6 g/100 g, without affecting acceptance.

It is an unpublished article that deals with reducing the ED and increasing the dietary fiber of sweet preparations, pointing out their difficulties and differences between different preparations created aiming at the prevention of chronic diseases.

The importance of packaging attributes for purchase decisions has generated interest in the research and food industry. As a matter of fact, innovation in packaging is constantly searching for new solutions that generate customer experience. The aim of this study is to analyse the effect of packaging attributes (protection, convenience, portability and storage, information, sustainability, branding and engagement) on consumer purchase intention of experiential packaging especially designed to provide an extraordinary sensory or interactive communicational experience and the influence of potential moderators.

The authors used a quantitative methodology based on the partial least squares (PLS) technique to estimate the structural model proposed. A purposely developed questionnaire was administered to a non-probabilistic sample of 1,489 European consumers. The questionnaire included questions related to consumers' perception of packaging attributes and purchase intention of different experiential packages.

The results indicate that packaging attributes are related to consumer purchase intention of experiential packaging. Engagement attributes show the strongest positive influence followed by branding and economy. However, attributes such as sustainability showed a negative effect on the purchase intention of these packages. The authors’ results also show the influence of gender, family structure and residential background as moderators of the relationships.

Customers' decision-making processes are strongly influenced by product packaging. However, little is known about how new technologies and design in packaging influence consumers' responses. This research provides evidence of the influence of packaging attributes on consumer purchase intention for experiential packaging, a proliferating area of research.
