Democracy is based on individuals' ability to give their opinions freely. To do this, they must have access to a multitude of reliable information sources (Dahl, 1998), and this greatly depends on the characteristics of their media environments. Today, one of the main issues individuals face is the significant amount of disinformation circulating through social networks. This study focuses on parliamentary disinformation. It examines how parliamentarians contribute to generating information disorder (Wardle & Derakhshan, 2017) in the digital public space. Through an exploratory content analysis--a descriptive content analysis of 2,307 messages posted on Twitter accounts of parliamentary spokespeople and representatives of the main list of each political party in the Spanish Lower House of Parliament--we explore disinformation rhetoric. The results allow us to conclude that, while the volume of messages shared by parliamentarians on issues susceptible to disinformation is relatively low (14% of tweets), both the themes of the tweets (COVID-19, sex-based violence, migrants or LGBTI), as well as their tone and argumentative and discursive lines, contribute to generating distrust through institutional criticism or their peers. The study deepens current knowledge of the disinformation generated by political elites, key agents of the construction of polarising narratives.

This study aims to compare how leading companies in Spain and in Spanish-speaking Latin America communicate corporate social responsibility or sustainability on their web pages. For this purpose, the pages of 68 companies were examined to establish the accessibility of such topics and to trace how their prominence and wording had evolved over time. The results show a trend toward greater uniformity in both Spain and Latin America, with corporate social responsibility/sustainability discourse gaining in prominence and "responsibility"-related terms being gradually replaced by those related to "sustainability." Various cases hint that changes in terminology may be unrelated to any clear distinction between both terms.

The construction, visualization and stabilization of public problems require the mobilization of civil society groups concerned about these issues to actively engage in the demand for actions and policies. This paper explores the institutional campaigns against human trafficking and sexual exploitation in Spain between 2008 and 2017 and their role in helping to shape this issue as a matter of public concern. Our aim is to identify the ideological basis of these campaigns through their representations of predominant actors, which have been systematized to identify possible mistakes and to help determine more effective actions with a greater capacity for mobilization. We applied a mixed content analysis combined with a semiotic model to evaluate the presence or absence of the different actors and their relevance in each case. Several lines of discourse have been reiterated across the 50 campaigns analysed: Curbing the demand for prostitution as a priority objective; the centrality of victims in the representations; the role of the consumer of paid sex as an accomplice to the crime; and the correlation between prostitution and human trafficking. We will also examine how these issues relate to the broader dispute on the status of prostitution in Spain. This will require a conceptual shift away from educational and social-oriented communication towards the structural causes, collective responsibility and transformative justice frameworks.

The main objective of this research is to analyze the content of YouTuber's videos that have the greatest impact on adolescents and their relationship with the construction of identity. The YouTube platform is one of the most commonly used by Spanish teenagers and around 70% of young people between 14 and 17 years of age prefer this network. YouTubers are perceived by young people as their equals, close people who share similar traits to their own, which facilitates rapid identification. A qualitative analysis of the content of 22 videos on the YouTube platform was carried out using the Atlas.ti program. The analysis led to several emerging codes related to the construction of adolescent personal identity. Most of the messages relating to personal identity were aimed at transmitting the self-impression of the YouTuber and the relationship of that self-impression with his gender identity, sexual orientation, and vocational identity. Also, family and peers appeared in the videos, especially as providers of social support. Teen followers include messages to support YouTubers, express their identification with the messages and use comment spaces to describe their own experiences, expressing the same concerns in the configuration of their identity. It is necessary to take into account this new space of interrelation to understand the development of young people's identity.

This article employs narrative analysis to examine how the media in 12 different countries characterize the "Teach for All" (TFA) teacher. Examining mass media narratives in these 12 countries illustrates that there are some remarkable commonalities in the narratives and character portraits co-constructed and propagated by the media. At the core of these narratives is the notion of a problem in education. This problem justifies the creation and emergence of a character, commonly constructed in opposition to traditionally certified teachers, who embodies the characteristics and attributes of the contemporary neoliberal subject. This article discusses the implications of this character's widespread representation; namely, how does the character construction influence the broader public perception about education and how is it contributing to the (re)imagination of the role of the teacher?

This study examines the linguistic resources by which foreign language (L2) learners express their ideological positions in online discussions taking place in a telecollaborative encounter during one semester. More specifically, the study attempts to decipher how L2 learners discuss and argue their points of view regarding their first culture, their second culture, and the topic in general, depending on the issue under discussion (immigration and nationalism or patriotism) and to the country where the learners were based (US or Spain). Twenty-four learners, organized into six groups, each with two students from the US and two from Spain, participated in three online forums. For the analysis, learners' postings were subjected to quantitative and qualitative content analysis applying two discourse-semantic subsystems of the Appraisal framework, Engagement--the linguistic resources used to reflect the writer's position and willingness to recognize alternative positions--and Attitude--the linguistic resources used to indicate positive or negative assessment of people, places, things, and states of affairs. This study concludes that there were clear differences in the discursive styles between both sets of learners and topics. Overall, for instance, the learners employed more monoglossic statements when discussing nationalism or patriotism rather than immigration and Spain-based learners made more use of judgment markers than their US-based counterparts did.

Interactive relationships in online learning communities can influence the process and quality of knowledge building. The aim of this study is to empirically investigate the relationships between network structures and social knowledge building in an asynchronous writing environment through discussion forums in a learning management system. The quality of the knowledge construction process is evaluated through content analysis, and the network structures are analyzed using a social network analysis of the response relations among participants during online discussions. Structural equation modeling is used to analyze relations between network structures and knowledge construction. Working on data extracted from a 6-week distance-learning experiment, we analyzed how 10 groups developed collaborative learning social networks when participants worked together on case resolution. The results show a positive correlation between cohesion and centralization, and the positive influence of the cohesion index and the centralization index on social presence and cognitive presence in knowledge building. However, this must be understood within the context of social networks in which messages sent to all group members occupy the center. This underlines the need for reinforcing participations that are directed to the group as a whole, and the importance of the fact the network contains both central and intermediate members. By contrast, we propose that the combination of analysis techniques used is a good option for this type of study while recognizing that it is necessary to continue validating the instruments in terms of their own theoretical suppositions.

This paper draws on research that aimed to explore the construction of gender relations in sport and physical education (PE) through a national study of Spanish university degree curricula. Spain is a useful case study through which to explore gender knowledge within sport and PE degrees, because, unlike many other countries, it has a common, national curriculum framework for its Physical Activity and Sport Science (PASS) degrees. In addition, it has recently passed a new law concerning the introduction of gender knowledge in higher education (HE). Drawing on Bernstein's (1990) framework of the pedagogic device, this paper examines how this HE gender policy becomes recontextualised as universities and lecturers interpret and translate this into the pedagogical texts that make up the PASS curricula. Purposive sampling was used to select 16 of the 37 universities offering PASS degrees in 2012/2013. The research analysed 16 PASS documents at the degree level and 763 individual subject handbooks. Using discourse analysis, the results showed where and how gender knowledge was incorporated and the extent to which the topic was presented coherently throughout the documents. The analysis revealed five categories of the (in)visibility of gender knowledge within the universities' instructional discourse. Gender knowledge is largely ignored in PASS curricular documentation, appearing, at best, in highly superficial ways. Despite a national policy requirement on universities to incorporate gender knowledge, this study shows how recontextualisation processes within specific universities' pedagogic devices operate to marginalise such perspectives within PASS curricula. The research also revealed the significance of individual agents committed to gender equity being situated, and having influence, throughout the pedagogic device. The paper concludes that without a much wider, critical engagement in knowledge about gender equity, PASS degrees will continue to reproduce rather than disrupt the gender relations that have traditionally characterised the field.

The aim of this paper is to analyse certain techniques of subjectivation in modern child-rearing and the way in which medical discourse leads to the construction of children through those techniques. As a case study, several manuals on childcare used during the first third of the twentieth century in Spain and France have been selected. A historical-genealogical perspective is adopted, according to which childhood is not a natural or ahistorical category, but depends on cultural practices. In Western countries, these practices have been strongly influenced by expert discourses. The techniques proposed in the manuals are identified and the theoretical justification for them analysed according to the socio-cultural and historical context. It is shown in what sense the practices recommended by doctors for mothers constituted a kind of early informal education contributing to the creation of future well-educated citizens.

This paper explores the impact of the tourism discourse on the self-representation strategies that a university in Catalonia adopts towards international students, and the extent to which these strategies connect with the stance of international students towards their study-abroad experience. The data were ethnographically collected during the academic year 2010-2011 and are analysed following a Content Analysis approach to explore how the university and international students project their perspectives on Catalan. The results show that the commodification of the Catalan language and culture is not only a strategy to increase the value of the university and recruit students, but also represents a way of projecting the Catalan national identity in a post-national era. This is not always accepted by the students, especially at the beginning of their stay, as they, like tourists, expect the host community to limit the use of the local language to specific and ritualised events and to adopt Spanish or English in interactions with them.

This article aims to demonstrate how the use of an online journal, a bilingual blog, can contribute to filling in the language and cultural gaps of foreign language learners. This case study focuses on the participation, interaction, motivation, language acquisition, feedback and cultural input improved by students of Spanish as a Foreign Language at the University of Queensland in Australia and students of English as a Foreign Language at the Universidad de Las Palmas de Gran Canaria in Spain. It demonstrates how this learner-directed instructional context allows intercultural and "language" exchanges, firstly between participants, as a peer revision exercise and secondly, as collaborative work and a discussion platform in the blog "GranCanBrisbaneEspanolEnglish".

Many recent studies on computer-mediated communication (CMC) have addressed the question of orality and literacy. This article examines a relatively recent subgenre of CMC, that of written online sports commentary, that provides us with written CMC that is clearly based on firmly established oral genres, those of radio and television sports commentary. The examples analyzed are from two English, two French, and two Spanish online football (soccer) commentaries. The purpose of the study is to examine oral traits and genre mixing in online football commentaries in the three languages and carryover from the spoken genres of radio and television commentaries to this developing genre, following Ferguson. Special attention is paid to Web page design. The study reveals that form and content of online football commentaries are strongly affected by the style of the online newspaper.

England switched to an opt-out system of consent in 2020 aiming to increase the number of organs available. Spain also operates an opt-out system yet has almost twice the organ donations per million population compared with England. We aimed to identify both differences and similarities in the consent policies, documents and procedures in deceased donation between the two countries using comparative qualitative content and discourse analysis. Spain had simpler, locally tailored documents, the time taken for families to review and process information may be shorter, there were more pathways leading to organ donation in Spain, and more robust legal protections for the decisions individuals made in life. The language in the Spanish documents was one of support and reassurance. Documents in England by comparison appeared confusing, since additions were designed to protect the NHS against risk and made to previous document versions to reflect the law change rather than being entirely recast. If England's ambition is to achieve consent rates similar to Spain this analysis has highlighted opportunities that could strengthen the English system-by giving individuals' decisions recorded on the organ donor register legal weight, alongside unifying and simplifying consent policies and procedures to support families and healthcare professionals.

A snapshot of communication research in Spain that uses qualitative methods as the dominant methodological perspective is presented. We conduct a content analysis to study the characteristics, objects and techniques that predominate in a census of 1,025 scientific productions from 2007 to 2018, which includes doctoral theses, projects and articles published in scientific journals. In the indexed publications, there is a certain lack of qualitative articles, despite the importance they have in doctoral theses and research projects. These researches use or triangulate qualitative methods, but not all techniques are used equally. Communication studies frequently resort to discourse analysis and in-depth interviews, but the presence of observations and discussion groups is minimal. The objects of study are also varied, although audiovisual formats prevail over journalistic formats and there is a growing interest in digital media and formats. Finally, at the author level, the results reveal parity, although the gender gap in the highest level studies is worrying. [ABSTRACT FROM AUTHOR]

In recent years we have witnessed a resurgence of populism, which has relied on the virality of social networks to deepen its roots in society and spread its ideas. This paper analyses the populist strategies used by all parties to viralise their messages in the online environment, regardless of ideology. The present research has also examined the possible existence of complementary strategies used by the parties' organisational profiles and those of their leaders. To this end, a content analysis has been carried out regarding the publications made on Twitter during the 2019 election campaign. The posts have been delimited to those made by the parties and candidates that attained the highest percentage of representation in the Congress of Deputies, which include the PSOE, PP, Vox, and Unidas Podemos. The findings show that all the parties under study resorted to this type of strategy. The parties closest to centre of the political spectrum, both right and left, used mostly a populist strategy aimed predominantly at attacking their adversaries, while Vox and Unidas Podemos articulated their discourse beyond this argument, with Vox appealing to the emotions of the nation and Podemos positioning itself as the peoples' advocate. Furthermore, a complementary strategy used by both the parties and their leaders has been identified, which fosters the expansion of these kinds of populist ideas. [ABSTRACT FROM AUTHOR]

Co-creation is a process that directly involves different stakeholders in the idea generation phase of a new product development process. A pool of 112 new aquaculture fish product ideas was obtained by applying a combination of creative and projective techniques to the co-creation process with consumers in six focus groups conducted in three European countries (Germany, France, and Spain). The subjectivity of qualitative data analysis (e.g., focus groups) is one of its recognised disadvantages. To overcome this drawback, a combination of specialised software (i.e., Alceste), along with word frequency, co-occurrence, and context checking, was applied to provide a different approach to data analyses in qualitative studies. The method identified the most salient dimensions behind the participants' discourse (naturalness, quality, ethics, price, and health) and inferred the importance those dimensions had for them, thus proving the existence of a correlation of 0.7 between what the participants said (frequency of mention) and what they liked the most (importance). Overall, the exploratory approach proposed is deemed useful for drawing key conclusions from qualitative research, thus offering an alternative to traditional content analysis. In future, the results obtained may be useful for selecting the co-created ideas with the greatest potential to be well received in the market. [ABSTRACT FROM AUTHOR]

Digital media and human mobility are intrinsically connected in an era where the human and the technological converge for representation and agency. In this context, platforms such as TikTok become prime spaces for diverse creative voices. This study constitutes the first exploratory analysis of TikTok as a medium where migrants embody their belonging through aspirational, performative, and self-governance creative and platformed practices. Through a content and discourse analysis of 198 videos gathered with relevant hashtags, using a Python script, we delve into the content created by Latin American migrants in Spain and the United States. The concept of platformed belongings is theorized in their use of TikTok's affordances and vernaculars to express aspirations to be part of certain socioeconomic, national, cultural, and digital communities. This is achieved through a range of storylines, from collective identities that align with expected values to stern challenges to oppressive norms. In this sense, we argue that platformed belongings enable migrants to reclaim their rights and negotiate existing symbolic boundaries by achieving different levels of visibility within this platform.

This paper aims at describing the eating experience of people diagnosed with and treated for laryngeal cancer. Going beyond the mere conceptualization of "after-effect" or the quantification of the disease's impact on the basis of standardized questionnaires, we present a qualitative analysis of the narratives of such experiences. Ethnographic study. Data is obtained from conversations, semi-structured interviews, participant observation, and written documents. A discourse analysis of the narrative information was conducted, with process coding and using the constant comparative method, inductive content analysis, category analysis, units of meaning associated with each other, and triangulation. The impact of cancer on eating processes is not limited to nutrition, but also affects the social and cultural value of food, which is put into question. The symbolic and social values which accompany the traditional way of eating are modified, which is connected with impaired quality of life. The impact on the eating process and its relationship with quality-of-life impairment are clear and connect with the importance of eating ways in culture and social organization. Greater attention should be paid to these contexts in clinical practice, which can affect even more than the impact on communicative processes. [ABSTRACT FROM AUTHOR]

The situation of lockdown experienced during the months from March to June 2020 changed the daily lives of people in Spain and their leisure circumstances. This study analyses the narrative representations that people construct when they watched streaming TV series, during the covid-19 pandemic. To access these representations, the Spanish texts that appear on the Internet are analysed, including social networks and other social media. The paper adopts quantitative approaches that use big data analysis complemented with other qualitative approaches and inspired by content and discourse analysis. Findings show that these narrative representations constructed through conversations are on three levels in which context is revealed: first, institutional and community; second, online or offline interpersonal relationships which mention people as facts or as aspirations of their daily lives; and third, personal lives in the reconstruction of the series, projected on the plot reconstruction and the identity of the actors.

The impact of the COVID-19 pandemic has reached most countries in the world. In the field of political communication, it is an unprecedented challenge for world political leaders. The aim of this research is to analyze the war rhetoric of Pedro Sánchez, President of Spain, one of the countries most affected by the pandemic. It takes his official speeches delivered from March 10 to April 22 as a reference. Content analysis is used with a procedure created for this case, under the approach of the Critical Discourse Analysis and combining a quantitative and qualitative perspective. After a thorough bibliographical review on the use of war rhetoric in public discourse, a corpus of lexical units w identified and interpreted in context: 101 lexical units and 359 phrases or metaphors with war or military reminiscences are detected in the 13 discourses of the corpus. The greatest "warlike weight" concentrates on the most serious moments and on the victims and those infected during the crisis. The war is the transmission vehicle used by the President of the Spanish Government to convey, in a simple, visual, and moving way, a government decision. [ABSTRACT FROM AUTHOR]

The aim of this article is to investigate the importance of family care in mental health and identify the shortcomings of the Spanish model of health care for the mentally ill. The empirical process comprised three qualitative procedures involving 37 experts from different regions of Spain. In order to guarantee the rigor of the data, a social worker discussion group was set up to create an interview script. Interviews were then carried out with 22 professionals who take care of people with mental illness in various public facilities throughout the country. A second focal group met three times to validate the categorizations analyzed in the interviews. The results of the empirical process indicate a need to remodel the mental health care system, which can be described with reference to five critical characteristics: 1) a lack of financial and human resources for mental health, 2) a lack of effective coordination among all the institutions and authorities involved, 3) a lack of quality resources aimed at rehabilitation and social reintegration as alternatives to institutionalization, 4) a lack of integrated care, and 5) a lack of a common healthcare framework for all professional workers in all the regions. A remodeling of the system is necessary to enable the rehabilitation, recovery, empowerment and development of people with SMD and thus ease the burden and improve the quality of life of family caregivers.

Objective: The objective of this study was to establish the factors that induce nursing professionals to present engagement with their work environment. Method: Qualitative study, using the communicative methodology, with nursing professionals from public and private centers in the city of Huesca. The statements were collected through communicative stories and discussion groups. Result: The methodology used has allowed the establishment of a set of engagement promotion measures in the studied environment. These measures are framed in the three main categories analyzed: the systemic or structural variables, the subject-oriented variables, and those that refer to the relationships between the subjects. Conclusion: Knowledge of the situation regarding engagement among professionals, and the issues that encourage or hinder its appearance, is essential in establishing measures that contribute to its development. The use of qualitative techniques has allowed for the discovery of situations that would have gone unnoticed. After analyzing the interviews and the discussion groups, the following were present: an important lack of recognition that the participants experience, and that contribute, in their opinion, to the appearance of burnout syndrome, and, the lack of cohesion as a collective.

In order to obtain a better understanding of the change of opinions and attitudes of the Spanish toward immigrants (Cea D'Ancona, 2004, 2007), this study analyzes the evolution of the media discourse referring to immigration in three Spanish newspapers: El País, El Mundo and La Vanguardia (2000-2008). In this work, a novel technique of semantic content analysis is applied to detect significant shifts in this discourse. The results show clear evidences of the evolution of the discourse regarding the immigration and its association with security issues and the demand for political solutions. [ABSTRACT FROM AUTHOR]

(2012) Tackling perinatal loss, a participatory action research approach: research protocol. Journal of Advanced Nursing 68(11), 2578-2585. Abstract Aim. The aim of this study was to promote changes to improve the care provided to parents who have experienced a perinatal loss through participatory action research. Background. The birth of a child is a joyful event for most families, however, unfortunately some pregnancies end in loss. Perinatal loss creates a heavy emotional impact not only on parents but also on health professionals, where in most cases there is an evident lack of skills, strategies and resources to cope with these kinds of situations. Design. Participatory action research is the methodology proposed to achieve the purpose of this study. Methods. Participatory action research consists of five stages: outreach and awareness, induction, interaction, implementation and systematization. The working group will include professionals from the Mother and Child Unit for patients at a tertiary level public hospital in Spain. The duration of the study will be 3 years since the approval of the protocol in January 2011. The qualitative techniques used will include group dynamics such as the SWOT analysis the nominal group technique, focus groups and brainstorming, among others that will be recorded and transcribed, generating reports throughout the evolution of the group sessions and about the consensus reached. Content analysis will be conducted on the field diaries kept by the participants and researchers. This project has been funded by the Andalusian Regional Ministry of Health. Discussion. Participatory action research is a methodological strategy that allows changes in clinical practice to conduct a comprehensive transformative action in the care process for perinatal loss.
