Jornalismo em quadrinhos: recursos subjetivos nas entrevistas desenhadas de Ricardo Siri Liniers Florianópolis
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Centro de Comunicação e Expressão. Jornalismo.Este Trabalho de Conclusão de Curso, uma monografia, trata das entrevistas desenhadas do quadrinista portenho Ricardo Siri Liniers. Publicadas pela primeira vez em agosto de 2010 no jornal argentino La Nación, elas combinam elementos do jornalismo, como o formato pergunta-resposta, e dos quadrinhos, como as imagens de traço caricatural. Liniers aparece sempre como um coelho – seu alter-ego – e a partir dessa inserção desenhada parece conseguir algo raro nas publicações jornalísticas de entrevistas: revelar como a subjetividade do entrevistador atua na construção de uma conversa com os entrevistados. Para embasar essa hipótese, o trabalho utiliza como referência estudos jornalísticos sobre entrevista, tomando-a pelo que Cremilda Medina defende que deve ser, um diálogo possíve

Corporate Governance of Insurance Firms After Solvency II
No full textUnder Solvency II, corporate governance requirements are a complementary, but nonetheless essential, element to build a sound regulatory framework for insurance undertakings, also to address risks not specifically mitigated by the sole solvency capital requirements. After recalling the provisions of the Second Pillar concerning the system of governance, the paper highlights the emerging regulatory trends in the corporate governance of insurance firms. Among others things, it signals the exceptional extension of the duties and responsibilities assigned to the board of directors, far beyond the traditional role of both monitoring the chief executive officer, and assessing the overall direction and strategy of the business. However, a better risk governance is not necessarily built on narrow rule-based approaches to corporate governance
Analysis and Simulation of SIRI Model for Dengue Fever Transmission
No full textObjectives: The aim of this study is to obtain SIRI model for dengue fever (DHF) transmission, conduct analysis, and simulation of SIRI model in disease-free and endemic and also to predict the number of DHF cases. Methods/statistical analysis: Dengue fever is caused by a virus carried by the Aedes aegypti and Aedes albopictus mosquitoes, the SIRI model is a modification of the SIR model. Analysis of the SIRI model use the Lyapunov function method, then
the data used in the simulation are assuming to show two possible dengue status are disease free and endemic status. The simulation also using the number of dengue case in Makassar city for showing the status of dengue fever transmission in Makassar city. Simulation models using Maple software are to predict the number of dengue cases in the following months. Findings: The results of this study are
the SIRI model of the transmission of dengue fever with variables that have recovered can be re-infected with dengue fever, analysis of the SIRI model of dengue transmission provides information that the equation system in the SIRI model which is asymptotically stable, it means that dengue cases always exist at a certain time and certain
region. The simulation results of the SIRI model in this study illustrate the number of dengue cases in the following months. While the first simulation found the basic reproduction number is R0 = 0.0366≤1 this means that dengue transmission is at an alarming stage, but the second simulation finds the basic reproduction number R0=31.2733>1, this means that, a person infected with dengue causes
eight individuals will be infected with dengue fever, so that it is in the endemic stage, and the last simulation using data of the number of dengue case in Makassar city found = 1, that means, Makassar city is a free disease case for dengue fever transmission. Application/improvements: SIRI model for DHF transmission is a mathematical health application. Model analysis guarantees existence, disease-free or endemic status, while simulation results can be used as a reference in DHF prevention

This study aims to investigate the predictive value of SIRI for 28-day outcomes in sepsis patients, and develop and validate a prognostic model for 28-day mortality.Methods: The demographic characteristics, disease severity, laboratory tests, treatments, and outcome measures were recorded from the adult sepsis patients. The restricted cubic splines and the ROC curve analysis were employed to evaluate the relationship and predictive capability of SIRI. Next, SIRI was categorized into tertiles, and univariate and multivariate Cox regression analyses were performed to assess its association with prognosis, supplemented by Kaplan-Meier (K-M) curves, and compare mortality differences. Patients from the First Affiliated Hospital of Soochow University were randomly allocated into training and internal validation sets at a 3:1 ratio, using the Boruta algorithm and LASSO regression and a prognostic model was constructed via logistic regression, while patients from the First People’s Hospital of Zhangjiagang City served as the external validation set. Then, the predictive performance, accuracy, and clinical utility of the model were validated using the ROC curve, Hosmer-Lemeshow test, calibration curve, and decision curve analysis (DCA).Results: The 380 patients from the First Affiliated Hospital of Soochow University and 240 patients from the First People’s Hospital of Zhangjiagang City were enrolled for the present study. The restricted cubic spline analysis revealed a nonlinear increasing trend in mortality risk with rising SIRI levels. The ROC curve analysis demonstrated that SIRI has superior predictive capability than the APACHE II and SOFA scores. When SIRI was categorized into tertiles, both the univariate and multivariate Cox regression analyses identified SIRI as significantly associated to 28-day prognosis (p< 0.001). The K-M curves further confirmed that higher SIRI levels correlated to lower 28-day survival rates (p< 0.001). In the training set, the Boruta algorithm combined with LASSO regression selected six independent risk factors: blood urea nitrogen (BUN), age, phosphorus (P), lactate (Lac), mechanical ventilation (MV), and SIRI. These were incorporated into the predictive model through logistic regression analysis. The ROC curve analysis revealed that the model exhibited good predictive performance across the training set (AUC: 0.851), internal validation set (AUC: 0.908), and external validation set (AUC: 0.792). The calibration of the model was verified using the Hosmer-Lemeshow test and calibration curve, while DCA was performed to confirm its clinical utility.Conclusion: SIRI is significantly correlated to the 28-day prognosis in sepsis patients, and has excellent predictive value for short-term outcomes. The prediction model that incorporated SIRI exhibited high prognostic accuracy.Keywords: sepsis, systemic inflammation response index, prognosis, prediction model, nomogra
Siri-ous Trouble: How Older Adults Handle Trouble Sources in First Exchanges with the Conversational User Interface Siri
No full textSiri-ous Trouble: How Older Adults Handle Trouble Sources in First Speech Exchanges with the Conversational Interface Siri
This PhD-project investigates how adults adapt to a ‘conversational interface’ (CI) (McTear et al., 2016) when they use it for the first time. Various forms of adaptation in so-called human-machine-interaction are known to emerge in the context of interactional trouble, i.e., problems of understanding or repair (e.g., Oviatt et al., 1998; Pelikan & Broth, 2016). These adaptations also constitute a known phenomenon in the adoption process of novice users of CIs (e.g., Luger & Sellen, 2016; Pins et al., 2020). However, insights into user adaptation are mostly drawn from retrospective self-reports in interview studies.
In contrast, this work aims to reconstruct the detailed conversational courses of ‘repair’ (Schegloff et al., 1977) and possible ensuing adaptation, applying ‘Conversation Analysis’ (Sidnell & Stivers, 2013) as method. The data collection consists of video recordings of 21 adults using the CI ‘Siri’ for appointment entries. Analysis of a collection of six older adults (65-74 y.o.) was guided by the following research questions:
1. What kind of trouble sources emerge?
2. How do older adults initiate or operate repair – with what kind of outcome?
3. (In what respect) do older adults act differently in comparison to younger adults?
Analysis reveals that older adults often show less variety in their conversational practices, e.g., by re-using their first choice of speech input in following appointment entries – even in cases of wrong entries. Moreover, they tend not to initiate or operate repair. Thus, successful task fulfilment occurs to a lesser extent than in younger adults.
