Introduction. In Peru, panettone, a brioche-type bread with raisins and candied fruit, is a product of high consumption throughout the year. Its preparation requires a large amount of flour, fat, and sugar, so its excessive consumption contributes to obesity problems and cardiovascular and metabolic diseases. Objective. To determine the nutritional contribution and evaluate the level of acceptance of panettone enriched with almonds, raisins, and dehydrated blueberries, as a healthy alternative, without modifying the characteristic organoleptic attributes recognized by its consumers. Materials and methods. In the physicochemical laboratory of the Universidad de Barranca (Lima, Peru), in December 2019, three types of panettone were formulated replacing the traditional filling with almonds, blond raisins, and dehydrated blueberries for a final composition of 40, 45, and 50 % w/w. They were subjected to sensory evaluation by ranking preference tests to qualify the attributes (color, smell, taste, and texture) and acceptance test with hedonic scale, to qualify the acceptance of the final product. The most acceptable product underwent physicochemical analysis to determine the nutritional contribution of the proposal. Results. The formulation with the highest acceptance was 45 % filler, even though the differences between treatments were not significant (p>0.05) The macronutrient content was similar to what is offered in the market (p>0.05). In relation to micronutrients, a contribution of 8 g of unsaturated fatty acids, 0.36, 5.8, 4.9, 33.3, 9.3, and 109 mg of vitamins B2, B3, E, iron, zinc, and calcium respectively, was observed per 100g g portion. Conclusion. Almonds, blond raisins, and dried cranberries improved the nutritional density of panettone, without significantly affecting the organoleptic characteristics of the product.

Introduction. Since 1990, there has been an increase in the rate of diseases associated with unhealthy diets and sedentary lifestyles, whose care is a challenge for health systems. This has aroused interest in functional foods, i.e., those that in addition to providing macro and micronutrients, provide substances that have a physiological effect on the body, which translates into improving the health of those who ingest them. Generically, these compounds are known as bioactives. Objective. To review the main bioactive substances reported in cheeses, as well as the role of microorganisms in their production and the biosynthetic routes of the main compounds. Development. Milk and its derivatives are food products consumed around the world and show a constant increase in their production and consumption. This market trend is due to its flavor and nutritional value. One of the most demanded dairy products in the world are cheeses. They are a source of substances such as peptides, fatty acids, vitamins, bacteriocins, organic acids, gamma aminobutyric acid, etc. all with important biological activity. Conclusion. The presence, quantity, and availability of the bioactive compounds present in the cheeses differ, as a result of the type of milk used for its elaboration, the type of microorganism used, either as starter or secondary culture, as well as the technological process employed.

Introduction. To know the factors that determine the rate of adoption of technician irrigation systems is important because of the water savings that could be obtained by increasing the number of units that use more efficient systems. Objective. To determine the factors that affect the rate of adoption of technician irrigation systems in Mexico. Materials and methods. A logit model was estimated where the dependent variable was the logit of the ratio of probabilities of using technician irrigation systems against other irrigation systems. The independent variables were: electricity price, water value, rainfall, temperature, number of over-exploited aquifers, farm size, utilization rate of production units that use sanitary measures, and educational level of agricultural producers. The estimate was made with data from Mexico’s 32 federative entities for 2019. Results. The results indicated that, if the electricity price and the water value increase by 10 %, the rate or probability of using modernized irrigation systems increases from 24.51 to 25.42 and 26.17 %, respectively. A 10 % decrease in rainfall would increase the probability of using modernized irrigation systems from 24.51 to 25.41 %, while with a 5 % increase in temperature, this probability would increase from 24.51 to 29.40 %. Conclusion. These results demonstrated the importance of economic and climatic conditions as factors that affect the use of technician irrigation systems, therefore, in saving water.

Introduction. The hen egg is a food of high nutritional value, with protein of high biological value and easy digestion, due to that it is indispensable to know what affects its quality when storing it. Objective. To evaluate the effect of temperature and days of storage on egg quality. Materials and methods. The trial took place between December 2019 and January 2020, in Palmares, Alajuela, Costa Rica. In two different moments, egg samples were taken from Hy Line Brown hens: 1000 eggs at the start of production (21 weeks of age) and 1000 eggs at peak of production (28 weeks of age). The eggs were stored at controlled (7-10 °C) and room ((18-26 °C) temperatures for up to 21 days. The following egg physical quality parameters were assessed: egg weight, eggshell thickness and resistance, Haugh units, and yolk color at 1, 4, 7, 14, and 21 days of storage, as well as a qualitative evaluation according to USDA standards (2000). Results. Egg weight was significantly lower at room temperatures and longer days of storage at peak production. Eggshell thickness and resistance presented a positive relationship with each other. Haugh units presented a significant decrease as storage days go by, with a higher negative slope for the eggs at room temperature. The storage temperature and days of storage degraded the perception and qualitative classification of eggs by the consumers, in higher proportion for the eggs at room temperature. Conclusion. Storage at room temperature and between 14 to 21 days were factors that affected the egg quality and the possible consumer’s perception towards this product.

The present work proposes an analysis of the journalistic coverage between April and August of the year 2009, of the painting exhibition ‘If new chains prepare... the little country marches’, by the Ecuadorian plastic artist Miguel Varea. In addition to the discussion based on academic texts on art and journalism, this study seeks to analyze the cultural information in the printed media, regarding the artist, in the midst of the conjuncture of his painting exhibition, the same one that was shown on three occasions, in the cities of Quito and Cuenca. For this, qualitative methodology is used and an observation of twenty-two journalistic documents is made, the same ones that have been disaggregated and inserted in a matrix to apply the news value as an alternative of content analysis, in order to identify the Main characteristics of the press regarding Varea's exhibition. This study will allow us to recognize the journalistic practices of different print media regarding the artist and his work, which has promoted a powerful social and political discourse. In this sense, it seeks to determine the most used journalistic genre, the recurring words in the texts, the headlines of the notes, the media that gave it the most coverage, identifying sources that contributed to the construction of the news under analysis. The main results indicate that the most used genre for coverage of Varea has been informative notes, followed by reports and opinion articles.

The Festival of Sanremo is arguably one of the biggest events on Italian television in terms of audience and prestige. It sits within complex socio-cultural dynamics and can be understood only through a lens that focuses on the ecology of Italian media and values songs as cultural objects (Tomatis, 2016). Indeed, acts happening on Sanremo’s stage can acquire a special significance in terms of their potential resonance (Facci et al., 2011) and the festival has often been used to spread political messages or raising awareness about social issues. In recent years, the festival has featured singers whose performances and character increasingly challenge and complicate traditional expressions of gender, with mixed, often polarized, receptions. The artistic choices of Amadeus (host of the 2019 through 2024 editions) and the authors reflect the trend of assimilation into the mainstream of queer or otherwise gender-defying signifiers in audiovisual pop productions (Ferrante, 2019). To zoom in on these processes, we draw our attention to performances of masculinities (Butler, 1990 & 2004; Connell, 2020; Feasey, 2008; Reeser, 2011) in the context of the 2022 edition of Sanremo. We will operate a visual analysis (Aubrey & Frisby, 2011; Russmann & Svensson, 2016; Tiindenberg & Baym, 2017) of the opening performances of three male artists, identifying three different ways of performing masculinity on the stage: Rkomi, Achille Lauro and Michele Bravi.

Netflix’s Maid chronicles the struggles of a heterosexual White single mother living in the Pacific Northwest of the United States. Using the concept of hegemonic masculinities and qualitative textual analysis, this study examined the 10 episodes of the limited series Maid to document the social construction of working-class and middle-class masculinities. Sean’s dysfunctional working-class life of six packs of beer and a single-wide trailer are juxtaposed against Nate’s offer of tidy suburban middle-class comfort and safety. I argue the program reifies stereotypical portrayals of working-class and middle-class men based on their homes, jobs, family background, leisure activities, and use of alcohol and drugs. Sean does not respect Alex’s bodily autonomy, her need for financial independence, or her need for freedom from emotional abuse. Similarly, Nate is unable to see past his entitlement toward Alex based on the material benefits he offers her like a reliable loaner vehicle, a clean two-story home, and pony rides for her daughter. I contend that Alex, the main protagonist, contests hegemonic masculinities to create her own space in the world without limitations dictated by the men in her life. Documenting how Maid tells the story of a woman and her romantic partners oppressed by hegemonic masculinities can provide insight into commonsense notions of romantic partnerships in the United States today.

Western criticism and study of Japanese cinema have traditionally prioritized the oeuvre of male filmmakers. Nonetheless, in the last decades a new generation of Japanese female directors has emerged, and the analysis of their films is necessary because of their attempts to rewrite the portrayal of women in cinema. This paper focuses on Momoko Andō, and it analyses her films A Piece of Our Life (Kakera, 2009) and 0.5 mm (0.5 miri, 2014). The results identified three features of her work: the presence of active women as main characters who resist patriarchal power, the inclusion of non-stereotyped LGBT characters, and the assertion of affective labor and the ethics of care as motor for social change.

Described by Saitō Tamaki in his essay Beautiful Fighting Girl (2011), this archetype corresponds to a series of patterns specific to Japanese fiction. From a Lacanian perspective, the author unravels the psyche of the otaku, tracing a structure where the barrier between fiction and reality are blurred through the magnetic field of sexuality and the hysterization of the subject towards fictional figures. Although, by definition, they are female characters who intervene in the course of their work and struggle to fulfill their will, these heroines perpetuate codes of fechitization stemming from Japanese heteropatriarchal culture. Thus, and by means of this paradox, outside the feminist post-structuralist currents of the West, characters oriented towards the desiring male gaze are created. However, Taro Yoko, in his video game NieR Automata (2017), exhibits characters that escape these canons, imposing a model closer to the socialist feminism of Donna Haraway's A Cyborg Manifesto (1984). Due the popularity of the Beautiful Fighting Girl in Japan and, by extension, in the West following recent neo-Japonisme waves this research is intended to serve those designers of videoludic narratives seeking feminist representations appropriate to contemporary postmodern discourses. To this purpose, an exhaustive analysis of the work's components and the symbolic contraposition of its elements will be developed.

The television debate is the most important moment of an electoral campaign, an act of political communication that generates a large amount of information and allows us to observe the qualities of political leaders. The current concept of media debate was born in the United States with the television confrontation between Nixon and Kennedy in 1960, marking a before and after in political communication and in the history of these media events. Electoral debates in Europe began parallel to the American cases. Sweden was the pioneer in 1958, followed by other countries such as Germany in 1969, France in 1974 or Italy in 1983; the first Spanish electoral debate appears in 1993 between Felipe González and José María Aznar. The United Kingdom incorporated the televised debate in 2010, becoming one of the countries with the least tradition in this field. To learn about the main characteristics of the European electoral debate, this research work analyzes a total of 119 debates held between January 2019 and June 2022, all of which were broadcast in 18 member countries of the European Union, including the United Kingdom. After applying content analysis, the data collected shows how debates in Europe with two candidates are slightly higher than those where there are more political participants. This study observes that the European debate is still between the «face to face» model and a format based on the presence of a larger number of protagonists.
