The aim of this paper is to determine chemical and sensory differences of between craft and industrial/or commercial beers. Beer market is nowadays booming and consumers are in the search of new and healthier products.

Here, commercial and craft beers were chemically analyzed and sensory evaluated. Chemical analysis included pH, bitterness, color, total polyphenol content and antioxidant activity. Likewise, 40 sensory descriptors were evaluated by trained panelists, including visual, olfactory and gustatory attributes. In addition, an electronic nose (e-nose) was tested to determine its suitability to discriminate beer type and/or style according to their volatiles profile.

Craft beers presented higher values of color, bitterness and antioxidant activity when compared to commercial beers. Sensory descriptors showed craft beers to be associated with the highest scores in visual, olfactory and gustatory descriptors. Data from e-nose explained 97% of the total variability of the volatile compounds in the analyzed beers, indicating the suitability of this device to discriminate beer types.

Results are of interest for design of marketing and selling techniques for craft brewery managers. In addition, cheap and easy-managing device as e-nose resulted in a valuable tool to monitoring beer quality.

Web site recommendation systems help to get high quality information. The modelling of recommendation systems involves the combination of many features: metrics of quality, quality criteria, recommendation criteria, user profile, and specific domain concepts, among others. At the moment of the specification of a recommendation system it must be guaranteed a right interrelation of all of these features. The purpose of this paper is to model a web site quality‐based recommendation system by an ontology network.

In this paper, the authors propose an ontology network based process for web site recommendation modelling. The ontology network conceptualizes the different domains (web site domain, quality assurance domain, user context domain, recommendation criteria domain, specific domain) in a set of interrelated ontologies. Particularly, this approach is illustrated for the health domain.

Basically, this work introduces the semantic relationships that were used to construct this ontology network. Moreover, it shows the usefulness of this ontology network for the detection of possible inconsistencies when specifying recommendation criteria.

Recommendation systems based on ontologies that model the user profile and the domain of resources to be recommended are quite common. However, it is uncommon to find models that explicitly represent the criteria used by the recommender systems, that express the quality dimensions of resources and on which criteria are applied, and consider the user context at the moment of the query.

The broader adoption of the internet along with web‐based systems has defined a new way of exchanging information. That advance added by the multiplication of mobile devices has required systems to be even more flexible and personalized. Maybe because of that, the traditional teaching‐controlled learning style has given up space to a new way of learning, which is more flexible and adequate to the learners needs. The purpose of this research is to go further into the semantic modeling of adaptive web based learning systems. Particularly, the paper focuses on those learning systems that consider in their definition the awareness of student's context in order to properly react to the student needs.

In this paper the authors introduce a semantic model of the student context in terms of an ontology network. This semantic model is explored in order to detect the “current situation” of students when they are navigating into e‐learning environments. The final objective is to enrich the adaptation functionality of e‐learning environments, being able to evaluate context data from personal profile, learning domain and technological situation.

In order to evaluate the semantic model defined, examples of detected situations are shown in accordance to specific e‐learning scenarios.

The paper covers definition of a flexible and modularized model by using ontology networks, which can be easily modified to incorporate new knowledge data, aiding the modeling of concepts from different learning environments.

The purpose of this paper is to analyze the life history of the Spanish Generation X over the last five decades.

Considering that the generational cohort concept can be identified from the marketing side as a market segment, this paper proposes to analyze the socio-economic and cultural context that has marked the different life stages of Generation X, and how they have related to brands according to their needs, desires and aspirations.

The results show that the customer journey can be considered a circular concept. The customer’s relationship with the brand can begin in childhood and continue into adulthood, such that the emotional relationship established with the brand as a child influences purchase decisions in adulthood.

Although limited to the analysis of Generation X and its relationship with brands, this paper shows the importance of knowing the socio-economic, legal and cultural context of a generation.

As a business implication, the importance of remarketing is evident as a business strategy that reinforces the emotional connection between the brand and the different generations.

From a social point of view, this paper shows the power of brands as an element of self-expression of the needs, tastes or preferences of individuals is evident.

This paper offers a different and innovative vision of the customer journey, taking into account the individual’s life cycle, and the way in which at each stage of life, he/she relates to brands in a different way.

While the literature has focused on the benefits granted by Deferred Action for Childhood Arrivals to undocumented youths in the USA, the purpose of this paper is to focus on the challenges encountered during the application process.

This paper is based on 60 semi-structured interviews with Latino undocumented youths living in the New York City and northern New Jersey metropolitan area.

The policy was intended to improve the inclusion of some undocumented youths in the USA by temporarily shielding them from deportation and providing them with a social security number. Analyses indicate great variation in youths’ experiences while applying for DACA, including program knowledge, financial impact, and application assistance – some of which was alleviated by respondents’ political engagement. This paper shows that participants suffered from anxiety due to the manner of implementation of the program.

This research is based on the self-disclosure of participants as undocumented youths. Fieldwork also took place in the New York/New Jersey metropolitan area, which is traditionally considered as more “immigrant-friendly” context than other areas of the USA.

This paper provides much needed information on the ways in which undocumented youths navigate the federal immigration system and the anxiety associated with it. This paper demonstrates the possibility that a federal policy whose goal is inclusionary could be implemented at the local level in such a way as to promote anxiety and alienation. It also highlights the role of political engagement in shaping immigrant youth’s experiences in the USA.

This paper's aim is to examine the relationship between intimate partner violence, childhood abuse and psychiatric disorders among 118 female drug users in treatment in Barcelona, Spain.

Secondary analysis of a cross‐sectional study of the psychiatric, behavioural and social risk factors for HIV. DSM‐IV disorders were assessed using the Spanish Psychiatric Research Interview for Substance and Mental Disorders; the Composite Abuse Scale assessed intimate partner violence and the Child Maltreatment History Self‐Report assessed childhood physical and sexual abuse.

The odds of experiencing intimate partner violence were 2.42 times greater among those with any depressive disorder (95 per cent CI 1.13, 5.20), over three times greater for those who reported ever attempting suicide (OR 3.20; 95 per cent CI 1.29, 7.94), met criteria for borderline personality disorder (OR 3.05; 95 per cent CI 1.31, 7.11), had been abused in childhood (OR 3.38; 95 per cent CI 1.45, 7.85) or currently lived with a substance user (OR 3.74; 95 per cent CI 1.29, 10.84). In multiple logistic regression, only living with a substance user (OR 3.42; 95 per cent CI 1.08, 10.86) and a history of childhood abuse (OR 2.87; 95 per cent CI 1.05, 7.86) remained significant in the model examining intimate partner violence victimisation.

The small sample size, together with the fact that the study was not originally powered to examine differences in intimate partner violence may have increased the possibility of type II errors.

Histories of psychiatric disorders, intimate partner violence and childhood abuse are common in female substance users in treatment. Research suggests that such histories result in poorer treatment outcomes. Histories of intimate partner violence and childhood abuse should be identified and addressed in substance abuse treatment to enhance treatment outcomes.
