Comunicação, culturas e estratégias. IV Jornadas doutorais comunicação e Estudos Culturais

(Excerto) A comunicação inscreve-se sempre em contextos culturais. Numa época dominada pelo regime da performatividade, da eficiência e da utilidade (Martins, 2015), a comunicação é cada vez mais pensada e usada de forma estratégica (Pinto-Coelho, 2005; Ruão & Kunsch, 2014). O mesmo se passa com aquilo a que chamamos cultura. Como nos diz George Yúdice (2006), a cultura, estando cada vez mais ligada à ideia de recurso ou de expediente, constitui-se como uma preocupação crescente de todos os setores da sociedade, quer para resolver problemas sociopolíticos, quer como instrumento que impulsiona o crescimento económico e a geração de emprego. Para professores e investigadores, estas novas orientações exigem problematizações outras, o abandono de instrumentos do passado e o favorecimento de uma reflexão e educação críticas. O presente livro, que reúne um conjunto de textos escritos por investigadores das áreas da Comunicação e dos Estudos Culturais que participaram nas IV Jornadas Doutorais em Comunicação e Cultura realizadas na Universidade do Minho, reflete este “ar dos tempos”. A edição inscreve-se num esforço permanente, desenvolvido pelo CECS — Centro de Estudos de Comunicação e Sociedade da Universidade do Minho — de promover a partilha de conhecimentos e experiências de pesquisa entre estudantes de doutoramento e pós-doutoramento das áreas das Ciências da Comunicação e dos Estudos Culturais. O encontro deste ano originou uma discussão frutífera à volta dos temas da comunicação, das culturas e dos seus usos estratégicos. O resultado é uma leitura, muito própria, de diferentes fenómenos da atualidade.

Current Challenges in Modeling Cellular Metabolism

Mathematical and computational models play an essential role in understanding the cellular metabolism. They are used as platforms to integrate current knowledge on a biological system and to systematically test and predict the effect of manipulations to such systems. The recent advances in genome sequencing techniques have facilitated the reconstruction of genome-scale metabolic networks for a wide variety of organisms from microbes to human cells. These models have been successfully used in multiple biotechnological applications. Despite these advancements, modeling cellular metabolism still presents many challenges. The aim of this Research Topic is not only to expose and consolidate the state-of-the-art in metabolic modeling approaches, but also to push this frontier beyond the current edge through the introduction of innovative solutions. The articles presented in this e-book address some of the main challenges in the field, including the integration of different modeling formalisms, the integration of heterogeneous data sources into metabolic models, explicit representation of other biological processes during phenotype simulation, and standardization efforts in the representation of metabolic models and simulation results.

Biotechnological valorization of waste cooking oils: lipase and microbial lipids production by Yarrowia lipolytica

[Excerpt] Waste cooking oils (WCO) generated from vegetable oils used at high temperatures in food frying, cause environmental problems and must be reutilized. New strategies to valorize these wastes are attracting a great scientific interest due to the important advantages offered from an economic and environmental point of view. A microbial platform can be established to convert low-value hydrophobic substrates, such as waste cooking oils, to microbial lipids (single cell oil, SCO) and other value-added bioproducts, such as lipase.

Self-esteem, assertiveness and resilience in adolescents institutionalized

The institutionalization of children and adolescents has been an increasingly visible problem in modern society. Unfavourable socio-economic conditions have been joining the behavior problems and school absenteeism. When the family fails in its competence for education, social security or the Court withdraws the child or adolescent to a host institution. The aim of this research was to characterize self-esteem, assertiveness and resilience of institutionalized adolescents in the northern region of Portugal and to establish associations with these dependent variables and gender, scholar level and duration of the institutionalization. For the purpose of this study a wider questionnaire was carried out, and validated with a smaller group. It was a transversal study following a predominantly quantitative methodology, with a convenience sample. The sample included 101 adolescents (55 female and 46 males) from eight institutions, aged between 11 to 21 years old (average 15.45). For self-esteem the Rosenberg Self-Esteem Scale (Rosenberg, 1965), already validate for Portuguese adolescents, was used. For assertiveness and resilience it was applied the Global Evaluation Scale of Assertiveness and the Global Evaluation Scale of Resilience (Jardim & Pereira, 2006) we previously adapted and validated for adolescents. Collected data was introduced in a SPSS database. A descriptive analysis was done to characterize the sample concerning all the variables. To establish associations between individual factors and dependent variables t test, correlations and non-parametric test were applied. Results indicated a relatively low self-esteem (28.03), with girls having a lower value than boys, without significant differences. No correlations were found between self-esteem and the time in the institution. Assertiveness of the sample is average (23.97) and higher for girls than boys, with a positive significant correlation with the scholar grade. Also the resilience is average (25.97), having girls a little lower mean than boys and no significant differences or correlations were found.

Careers, identities and professionalization. A study on doctors about their social representations related to the labor market today and its foreseeable future

This study is in line with the analyses of university and working career in their interaction in relation with conditioning factors. It comprises two central issues: the issue of identity bound to the issue of professionalization within the domain of training and employment. Nowadays, professionalization of the individuals, inside a troubled occupational world, demands the implementation of mechanisms favoring the development of both the individuals and the institution in which they work. All this has an impact at the local, regional and even national levels. Three levels of analysis interplay from a sui generis perspective: macro-meso-micro-macro (Aparicio, 2005; 2007a; 2007b, 2013a, 2014, 2015 b, d – See the Three- Dimensional Spiral of Sense Theory). The aim was to be aware of the doctors’ representations regarding the value of such degree under the present “degree devaluation”, and its impact on the professional future as well as on the core issues of the labor market which need urgent measures with a view to a belter interaction between the two systems. The methodology used was quanti-qualitative (semi-structured questionnaires, interviews, and hierarchical evocations). The population consisted of doctors (2005-2012) from the National University of Cuyo, in Argentina. The results helped us understand the nucleus of such representations and the peripheral aspects by career and institution, thus revealing professional and disciplinary identities. The professional identities show the situated needs in terms of professionalization within the different contexts and, particularly, within the labor market.
