No full textRe-reading men’s facial hair : The case of the modernization of the Turkish civil service
No full textThis paper presents a critical analysis of the links between modernization and masculinities in Türkiye through the case of the regulation of men’s hair in the civil service. The Turkish civil service is an institution where the state has accumulated and deployed power, disciplined its civil servant employees, and shaped and transformed masculinities as part of the broader process of modernization. Both the civil service as a research field, and men’s hair, despite its powerful symbolic importance in politics, have been neglected in critical studies on men and masculinities. To fill this gap, four momentous changes in civil service history in Türkiye are examined, as a part of the modernization project over the last two centuries and simultaneous reciprocal interrelations of macro- and meso-processes with men’s facial hair. These changes have been targeted towards or resulted in transformations of men’s facial hair in the civil service, in turn constructing state-sanctioned masculinities in the civil service and society.This work was supported by The Scientific and Technological Research Council of Türkiye (TÜBİTAK), 2219-International Postdoctoral Research Fellowship Program for Turkish Citizens [grant number: 1059B191900613].</p
Att leva med Amyotrofisk lateralskleros i den palliativa fasenEn litteraturstudie om patienters upplevelser
No full textBakgrund: Amyotrofisk lateralskleros (ALS) är en progressiv och dödlig neurodegenerativsjukdom i det centrala nervsystemet (CNS). Sjukdomen bryter ner motorneuron vilket leder till förlust av viljestyrd muskulär funktion. Förväntad livslängd för ALS är cirka 3–5 år efter bekräftad diagnos. Då bot inte finns blir symtomlindring central genom palliativ vård. Katie Erikssons omvårdnadsteori om mänskligt lidande användes då fokus för ALS är att lindrasymtom och lidande.Syfte: Syftet med studien var att beskriva patienters upplevelse av att leva med amyotrofisklateralskleros i det palliativa skedet.Metod: Litteraturöversikt med systematisk sökning och en deskriptiv design. Systematiska databassökningar genomfördes i databaserna Cinahl och PubMed. Dataanalys genomförd med en integrerad analys. 13 vetenskapliga artiklar inkluderades till studien.Resultat: Resultatet sammanfattades under 3 teman: Fysiska utmaningar och lidande, Emotionellt och existentiellt lidande och Att leva i ovisshet och förlust av kontroll. Under dessa teman framkom tillhörande underteman för att få ett systematiserat resultat. Slutsats: Vid en ALS diagnos uppstår en mängd förändringar på livet och vardagen. Sjukdomen bidrar till en påverkad autonomi, mening och upplevd självbild. Patienter upplevde vården vid ALS varierande med kommunikation, information, utbildning och bemötande som viktiga faktorer för att acceptera samt förstå sin sjukdom.
I gränslandet mellan löfte och villkor : En kritisk diskursanalys av gigföretags webbmaterial och uppdragstagares erfarenheter
No full textThe digital development of the Swedish labor market has given rise to a growing gig economy in which work is organised through digital platforms and carried out as task-based services. This form of work organisation has become the subject of both media and political debate. Previous research has also pointed to various risk factors associated with gig work. The aim of this study has therefore been to examine how the gig companies Wolt and Foodora linguistically represent work on their websites, and which understandings of work are thereby produced. The study further aims to relate these representations to narratives from individuals who have performed tasks for the companies. A critical discourse analysis was conducted on the web material collected from Wolts and Foodoras websites. The interview material, conducted by Arbetets Musuem, was reviewed and analysed thematically. The theoretical framework of the study draws on Fairclough’s critical discourse analysis, Standings concept of precarity and theories of modernity based on Bauman and Giddens. The findings show that gig work is linguistically represented through a discourse of flexibility and entrepreneurial subject positioning. Through these representations, a shift of risk from the companies to the workers is enabled, alongside an obscuring of responsibility and risk. The interview material further indicates that the gig workers experience contrast with the companies linguistic representations of the work.Den digitala utvecklingen på den svenska arbetsmarknaden har medfört en växande gigekonomi där arbete organiseras via digitala plattformar och utförs som uppdragsbaserade tjänster. Detta sätt att organisera arbete har blivit föremål för både medial och politisk debatt. Forskning pekar även på riskfaktorer med arbetet. Syftet med studien har därför varit att undersöka hur gigföretagen Wolt och Foodora språkligt framställer arbetet på sina webbsidor och vilka föreställningar av arbetet som därigenom kan produceras, samt att sätta dessa framställningar i relation till uppdragstagares erfarenheter av arbetet. På webbmaterialet som hämtades från Wolt och Foodoras hemsidor genomfördes en kritisk diskursanalys. Intervjumaterialet som bestod av intervjuer genomförda av Arbetets museum granskades och tematiserades. Studiens teoretiska ramverk utgjordes av Faircloughs kritiska diskursanalys, Standings begrepp om prekaritet samt modernitetsteori med stöd i Bauman och Giddens. Resultatet visar att gigföretagen språkligt framställer arbetet genom en flexibilitetsdiskurs och entreprenöriell subjektspositionering. Därigenom möjliggörs en riskförskjutning från företagen till uppdragstagaren och osynliggörande av ansvar och risk. Intervjumaterialet visar att uppdragstagares erfarenheter kontrasterar mot företagens språkliga framställningar
A general formulation of the survival problem in a power-law reaction–diffusion model: Emergence of a critical parameter
No full textThe survival of a population confined within a bounded habitat is a classical problem, traditionally analyzed in terms of the habitat size. In the linear case, persistence is ensured when the domain length exceeds a critical size lc. In nonlinear models, however survival conditions become considerably more complex and may even take less intuitive forms, such as l≤lc. In this context, Colombo and Anteneodo (2018) studied the power-law reaction–diffusion model ut=D(uν−1ux)x+auμ, with μ,ν>0, accompanied by hostile boundary conditions, determining survival thresholds in terms of habitat size for initially homogeneous populations. In this paper, we propose a general formulation of the persistence question by rewriting the power-law reaction–diffusion model in terms of suitable nondimensional variables. This approach reveals that persistence can be naturally expressed through a parameter [Formula Presented]. We show that there exists a critical value Qc depending on μ, ν and the initial distribution, such that survival occurs whenever Q≥Qc. This more intuitive condition reconciles the various survival criteria within a unified framework. To further explore this condition, we analyze two one-parameter families of initial distributions, including the homogeneous case, and apply a finite-difference scheme to estimate Qc. Conversely, for given model parameters μ, ν, l, n0, and the growth and diffusion coefficients a and D (and consequently the value of Q) we use the numerical algorithm to determine how concentrated the initial distribution must be to ensure population survival
Rethinking the future of fishing in Spain: Stakeholder perceptions, conflicts, and structural challenges.
No full textThe Spanish fishing sector, one of the most important in Europe, faces structural challenges related to governance, digitalisation, working conditions and socio-economic sustainability. Despite the technological advances and the regulations implemented, problems such as job burnout, job insecurity and tensions between actors in the sector persist. This study analyzes the perceptions of 182 key stakeholders of the fishing sector in Spain through a structured survey based on five dimensions (Economy, Society, Politics, Technology and Social Context) and four fisheries performance indicators. Random Forest models were used to identify the most influential factors in the perception of the state of the sector. The results reveal that job burnout and professional profile are the main determinants of fishing perception, followed by the implementation of technology, which has mixed effects on the sustainability of the sector. A marked fragmentation in perceptions is observed according to the interest group, with fishermen and government agents showing a more negative view compared to scientists and NGOs. In addition, conflicts within the sector exceed cooperative actions in frequency, evidencing fragmented governance and difficulties in reaching consensus. These findings underscore the need for more inclusive management strategies, which include the perception of all actors and promote a balance between sustainability, workplace well-being and technological innovation
Exploring Green Software for Management: Tourism as an Emerging Research Field
No full textGreen software has become increasingly relevant in the debate on sustainability, addressing the environmental impacts of digital technologies and their application in management. This study investigates the development of research on green software for management through a hybrid bibliometric and systematic approach, focusing on whether tourism emerges as an underexplored research field. Using data from the Web of Science (1991–2024), we analyze publication trends, leading authors, countries, institutions, and thematic clusters. Results show a growing but fragmented body of literature, where tourism appears only marginally yet offers promising opportunities for further exploration. The thematic map reinforces tourism as a potential field of inquiry, highlighting its increasing exposure to sustainability challenges. The study contributes by providing a comprehensive overview of green software research, identifying gaps, and suggesting directions that emphasize the need to expand applications in tourism and strengthen the integration of technology with sustainable management practices
El uso educativo y social del smartphone de los jóvenes universitarios
Full text linkEl smartphone se ha convertido en un elemento esencial en la vida de los jóvenes, desempeñando un papel clave en actividades sociales y educativas. Este estudio exploratorio, de diseño no experimental y enfoque cuantitativo, analiza cómo los estudiantes universitarios utilizan el smartphone a nivel educativo y social, así como los espacios en los que lo emplean. La muestra incluyó a 282 estudiantes. El análisis de los datos empleó estadísticas descriptivas y pruebas paramétricas, como la correlación de Pearson y la prueba t de Student. Los resultados revelan que los estudiantes valoran de manera equitativa el uso educativo y social del dispositivo. Aunque actividades como la búsqueda de información y las redes sociales son comunes, el uso educativo predomina en contextos tranquilos como el hogar o el transporte, mientras que el uso social es más frecuente en espacios públicos. Estos hallazgos refuerzan la polivalencia del smartphone en la vida universitaria
Dietary and microbial influences on intestinal immune activation in treated people living with HIV and a Th17-deficient mouse model
No full text19 páginas.El artículo analiza la relación entre la dieta mediterránea y la salud intestinal en dos modelos distintos: un grupo clínico de personas con VIH y un modelo experimental en ratones.Para lo cual se analiza la riqueza y composición de la microbiota intestinal y la expresión de parámetros de translocación microbiana y marcadores inflamatorios en una muestra de personas que viven con el VIH con un período prolongado de control viral y un recuento elevado de linfocitos T CD4+, así como para evaluar la influencia de una dieta mediterránea en estos resultados.
Además de analizar los efectos de la dieta en un modelo experimental, estos parámetros se evaluaron en paralelo en ratones Batf−/−, caracterizados por la depleción del gen BATF. Este gen es importante para la producción de IL-17 y, por lo tanto, para la diferenciación de linfocitos T CD4+ en linfocitos Th17. De hecho, el recuento de linfocitos Th17 en sangre periférica de estos ratones se redujo significativamente, mientras que se detectó un aumento de linfocitos T reguladores. En teoría, esta deficiencia de células Th17 podría conducir a un deterioro de la función inmunitaria intestinal y podría aumentar la susceptibilidad a la disbiosis y la translocación bacteriana, lo que ofrece un modelo relevante para el estudio de la activación inmunitaria crónica, similar a la observada en las personas que viven con el VIH tratadas
