This study aims to investigate unripe carob pod as a source of antioxidant molecules useful in the eco-friendly synthesis of a gelatin conjugate. This one was involved in the preparation of gummies able to produce remarkable human health benefits.

Eco-friendly strategies (ultrasound-assisted extraction, low temperatures and eco-friendly solvents) were employed in the extraction of active molecules. Antioxidant molecules were involved in the grafting reaction with gelatin chains (ascorbic acid/hydrogen peroxide couple as initiator system). Gelatin conjugate represents a useful material able to prepare gummies with remarkable rheological and antioxidant performances over time.

Experimental results confirmed that the green approach allowed the achievement of extracts with remarkable antioxidant properties due to the presence of phenolic moieties. Gelatin conjugate synthesis preserved these functionalities, usefully exploited in the preparation of gummies with significant structural and biological features.

Compared to the literature data the preparation of the gummies with outstanding biological properties was performed by employing functional gelatin synthesized by an eco-friendly approach.

Solar PV direct-driven air conditioner with grid connection, home used small temperature difference heat pump, smart house energy information and control system are appropriate energy technologies with reduced CO₂ emission, which can be applied efficiently in the hot summer and cold winter climate zone. More useful data will be obtained in the future demonstration tests in Sino-Italian Green Energy Lab.

This work shows combining renewable energy technologies and information technologies is crucial to improve the energy efficiency and the comfortableness for indoor environment.

The purpose of this paper is to describe the relationship between migratory status, the use of legal and illegal psychoactive substances and psychological disorders perceived in a sample of minors.

A transversal multicentre study was carried out with interviews with young people aged 13-16 years recruited from middle and high schools in Italy.

The results show the implementation of a process of normalization in terms of the presence of legal and illegal psychoactive substances in the living contexts of the minors, of their widespread early use and of a substantial indifferentiation in the reasons for use (e.g. pleasure, curiosity, fun). Youths born in Italy with at least one non-native parent are noteworthy for an elevated prevalence of perceived psychological disorders and for particular lifestyles linked to the use of marijuana, alcohol abuse and the intensive consumption of tobacco. Second-generation minors show symptoms of psychological malaise, anxiety and depression before which the use of substances appears to realize a particular form of self-cure.

This study presents some objective limits that indicate prudence in generalizing the results: only those who obtained consent from their parents were interviewed and the information communicated in the interviews could have been influenced by various factors, including the situation and the location. The authors used a standard definition of binge-drinking (Valencia-Martín et al., 2008). Actually, different criteria (i.e. number of drinks, time of consumption, etc.) and formulations of the question are used in different surveys, showing that there is as yet no consensus definition of binge-drinking. Nevertheless, the term has become somewhat confusing as it is often used as a synonym of drunkenness, making cross-cultural comparisons difficult (Beccaria et al., 2014). These are aspects that limit the generalizability of the results to the interviews alone and do not allow for prevalence estimates. Nevertheless, the results offer useful indications for future prevention projects specifically oriented to early adolescence.

The results of the study, on the one hand, document the growing use of legal and illegal proactive substances among minors and the relative cultural trend in this particular age band, testified to by the high number of those who have been present in situations of consumption to whom the substances were offered; on the other, they evidence a subpopulation of youths born in Italy with at least one non-native parent (i.e. second generation of immigrants). These youths stand out for an elevated prevalence of perceived psychological disorders and for their particular lifestyles connected to the use of marijuana, alcohol abuse and the intensive consumption of alcohol. This is also the group with the highest percentage of mothers alone in the family.

A group of adolescents living in a monoparental family, that is, with the mother alone emerges, and as the literature has shown, family structure and poverty are linked (Landale et al., 2011; Svensson and Hagquist, 2009). In fact, such mothers, even those with a high level of education, are mostly unemployed. Adolescents with a single parent often not only face resource deficits but also other risk factors, such as high family stress, inadequate supervision, multiple family transitions and frequent residential moves. Specifically, these second-generation adolescents are female and they manifest sensation-seeking behaviours, but without drug abuse.

The results of the study show new and little-known aspects of the multicultural Italian society that is changing profoundly that should be explored in more detail by targeted research that also focussed on structural factors relatable to specific social positions. In this framework, a particular subgroup, i.e. the second-generation minors, shows symptoms of psychic malaise, anxiety and depression in terms of which substance use seems to realize a form of self-cure.

From literature, an uncovered issue around the customer-based brand equity (CBBE) is detected: the influence of sensorial preferences on the relationship between social media communication and CBBE. The purpose of this paper is to investigate the effects produced by social media brand communication – both firm-created content (FCC) and user-generated content (UGC) – on CBBE, according to the sensorial preferences in the beer industry.

A literature review has been used to develop a research model and hypotheses. The research is based on online survey carried out on a sample of 183 valid questionnaires of Italian active fans and followers in the beer industry. A multi-group analysis applied to structural equation modeling is used.

The sensory dimension prevails limiting the operating range of brand awareness that does not strongly affect CBBE. In brand equity development’ process, non-sensorial users do not consider sensorial preferences. The brand equity can become stronger by stimulating the reaction of customers through firms’ communication by using social media platforms. Therefore, the quality of peer interactions in the social media communication has a positive impact on brand loyalty. When firms use social media communication to increase overall brand equity, they have to foster and monitor FCC and UGC responses that affect different CBBE components.

The paper provides empirical evidence about the relationship between social media communication and CBBE, according to the importance given to sensorial preferences by beer lovers. This can be considered as the first study on this specific topic focused on the CBBE issue.

Many firms are investing in digital services to improve customer experiences. Virtual service agents, or “e-service agents” (“e-agents”) such as chatbots, are examples of these efforts. Chatbots are types of virtual-assistant software programs that interact with users through speech or text. This paper aims to investigate whether the perceived hedonic and utilitarian attributes of chatbots can influence customer satisfaction and, consequently, their relationships with brands.

Data were collected through a questionnaire-based survey among a sample of Italian consumers. A convenience sampling technique was used. Data were then analyzed through Partial Least Squares Structural Equation Modeling to provide a prediction-oriented model assessment. The findings were then complemented with an importance–performance map analysis (IPMA) to gain more detailed insights and actionable guidelines for managers.

The findings highlighted that the perceived hedonic and utilitarian attributes of chatbots positively influenced customer satisfaction and improved customer relationships with the brands. However, the IMPA highlighted that the performance levels of two most important attributes – system quality and experience with chatbot – could be improved resulting in additional improvements of customer satisfaction.

This study suggests the importance of firms’ investments in and adoption of e-agents to strengthen consumer–brand relationships and of considering both the hedonic and utilitarian attributes of their e-agents.

This article attempts to enrich and consolidate the growing body of literature concerning the impacts of new technologies – and, specifically, chatbots – in service marketing.

The paper aims to investigate the practices facilitating the transformation of healthcare services, understanding the resulting outcomes in terms of well-being and uplifting changes. a systematic literature review (SLR) focusing on analyzing the healthcare sector under the transformative service research (TSR) theoretical domain is conducted to achieve this goal.

Employing a structured SLR developed based on the PRISMA protocol (Pickering and Byrne, 2014; Pickering et al., 2015) and using Scopus and WoS databases, the study identifies and analyzes 49 papers published between 2021 and 2022. Content analysis is used to classify and analyze the papers.

The SLR reveals four transformative practices (how) within the healthcare sector under the TSR domain, each linked to specific well-being outcomes (what). The analysis shows that both practices and outcomes are mainly patient-related. An integrative framework for transformative healthcare service is presented and critically examined to identify research gaps and define the trajectory for the future development of TSR in healthcare. In addition, managerial implications are provided to guide practitioners.

This research is among the first to analyze TSR literature in the context of healthcare. The study critically examines the TSR’s impact on the sector’s transformation, providing insights for future research and offering a roadmap for healthcare practitioners to facilitate uplifting changes.

The purpose of this article is to give a non‐technical overview of some of the technical progress made recently on tackling three fundamental problems in the area of formal knowledge representation/artificial intelligence. These are the Frame Problem, the Ramification Problem, and the Qualification Problem. The article aims to describe the development of two logic‐based languages, the Event Calculus and Modular‐E, to address various aspects of these issues. The article also aims to set this work in the wider context of contemporary developments in applied logic, non‐monotonic reasoning and formal theories of common sense.

The study applies symbolic logic to model aspects of human knowledge and reasoning.

The article finds that there are fundamental interdependencies between the three problems mentioned above. The conceptual framework shared by the Event Calculus and Modular‐E is appropriate for providing principled solutions to them.

This article provides an overview of an important approach to dealing with three fundamental issues in artificial intelligence.

The purpose of this paper is to propose a new management approach to analyse the processes of museums in the experience logic and, on the basis of such a model, to study the management processes of the National Gallery of the Marches in Urbino, one of the most important museums in Italy.

This study adopted a qualitative methodology and a descriptive-exploratory approach. The proposed model, which aimed to create and manage experiences and transformations in museums, was tested in the National Gallery of the Marches by adopting the case study method.

The empirical research underlined the partial application of the proposed model in the museum under examination and the potential for the museum to improve the offering value to its visitors.

Although a single case was investigated, the present work offers a preliminary theoretical contribution, which is useful for perfecting the conceptual framework and applying it to a wider number of cases.

The management of the National Gallery of the Marches should first plan a greater number of more detailed experiences and transformations around the theme of the Renaissance, and promote the active role of visitors. Second, it should improve the communication of the offer, especially through social networks. Third, personnel (especially front office) should be motivated and trained to create value for visitors.

The paper aims at developing a new management approach for the museums to create value for the visitors and museums by bringing the insight of the experience logic into the field of cultural heritage management.

This study aims to characterize several wine consumer segments who were “likely” to sample (i.e. taste before purchasing) wine from vineyards using cover crops, a sustainable production practice that reduces herbicide applications, and identify those with a greater probability of being a viable target market based on survey responses.

A total of 956 wine consumers from the Mid-Atlantic and boarding US states were separated into segments based on an ECHAID (exhaustive Chi-square automatic interaction detector) classification tree from internet survey responses.

Out of the 12 created segments, 6 (n = 530, 72% of training data) contained participants who were at least 1.02 times (index score =102%) more “likely” to try the wine compared to the overall sample and were willing to pay $18.99 for a 750-mL bottle of the wine, which included a $1 surcharge to cover associated production costs. Of these, three (n = 195, 26%) had the greatest potential for which a marketing plan could be developed (index scores of 109%–121%), with over half in each segment willing to pay $20.99 for the bottle of wine, which could motivate growers to consider implementing this sustainable strategy.

Although several segments of participants were “likely” to sample the sustainably produced wine, an ECHAID classification tree allowed us to identify participants who would not pay $18.99 for a 750-mL bottle of wine, even after learning about the use of cover crops and the trade-off ($1 bottle surcharge). By narrowing the number of potential “likely” segments to those with a greater potential of sampling the wine, more purposeful marketing strategies can be developed based on demographics, attitudes, and behaviors defined in the model.
