Automated network resilience optimization using computational intelligence methods

This paper presents an automated optimization framework able to provide network administrators with resilient routing configurations for link-state protocols, such as OSPF or IS-IS. In order to deal with the formulated NP-hard optimization problems, the devised framework is underpinned by the use of computational intelligence optimization engines, such as Multi-objective Evolutionary Algorithms (MOEAs). With the objective of demonstrating the framework capabilities, two illustrative Traffic Engineering methods are described, allowing to attain routing configurations robust to changes in the traffic demands and maintaining the network stable even in the presence of link failure events. The presented illustrative results clearly corroborate the usefulness of the proposed automated framework along with the devised optimization methods.

Interpersonal and attitudinal factors in women's work role: Cross-cultural comparison

The last four decades have seen a dramatic increase in the number of women entering employment. This is particularly true in Europe and although more European women are working outside the home, the patterns of female employment have changed very little. An analysis of these patterns is presented. It was found that women continue to dominate specific fields, particularly teaching and service providing. An investigation of the interpersonal behavior differences among 117 American women from the southeastern United States in three work roles--homemakers, women in traditional occupations, and in nontraditional occupations--was conducted and the sex-role orientation, attitudes toward success, and demographic indicators were examined in order to consider the interplay of these variables with female occupational role and interpersonal behavior. A second focus of the study is on the cross-cultural comparison of the psychological and work variables in women of two different cultures: America and Portugal. Thirty-one Portuguese women were a preliminary comparison sample. The American results showed significant differences between groups in self-perceived interpersonal behaviors and the findings contradicted current stereotypes. The cross-cultural data, although preliminary, indicates differences between the countries in social desirability, aggressive and assertive behaviors, and in sex-role attitudes, which seem to reflect the different stages of economic development.

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.

The construction of professional identities in the contexts of work

This chapter identifies and analyzes some characteristics of working situations that are important in the construction of professional identities. It is claimed that professional identity presumes a dynamic process and is constructed and reconstructed in social situations and interactions. Work has a central place in the life of individuals and societies. The contexts of work are places par excellence for investment, expression, negotiation and recognition of the actor themselves and of others. They are, thus, situations for the attribution offeelings about work, ofrelational transactions, oflearning and production of professional know ledge, which are fundamental elements in the (re )construction of professional identity and which are emphasized here below.

Stress, cognitive appraisal, and psychological health: testing instruments for health professionals

The job of health professionals, including nurses, is considered inherently stressful (Lee & Wang, 2002; Rutledge et al., 2009), and thus it is important to improve and develop specific measures that are sensitive to the demands that health professionals face. This study analysed the psychometric properties of three instruments that focus on the professional experiences of nurses in aspects related to occupational stress, cognitive appraisal, and mental health issues. The evaluation protocol included the Stress Questionnaire for Health Professionals (SQHP; Gomes, 2014), the Cognitive Appraisal Scale (CAS; Gomes, Faria, & Gonçalves, 2013), and the General Health Questionnaire-12 (GHQ-12; Goldberg, 1972). Validity and reliability issues were considered with statistical analysis (i.e. confirmatory factor analysis, convergent validity, and composite reliability) that revealed adequate values for all of the instruments, namely, a six-factor structure for the SQHP, a five-factor structure for the CAS, and a two-factor structure for the GHQ-12. In conclusion, this study proposes three consistent instruments that may be useful for analysing nurses’ adaptation to work contexts.

Horário por turnos : análise do seu efeito numa empresa do sector industrial

O presente estudo teve por objetivo analisar os possíveis efeitos do trabalho por turnos, incluindo o turno noturno, a nível da saúde, vida familiar e social, numa empresa do sector da indústria. Foi construído um questionário que abordava questões relativas aos dados sociodemográficos, organização temporal do trabalho, qualidade do sono, exigências da tarefa e envolvimento, saúde, vida familiar e social, e posteriormente foi aplicado a uma amostra de 24 trabalhadores com idades entre os 29 e os 52 anos (41,58±5,79 anos). Os resultados mostram uma tendência para doenças como a obesidade, colesterol elevado e manifestação de sintomas relacionados com problemas digestivos nos trabalhadores que trabalham por turnos à [sic] mais anos. Antes do primeiro turno noturno o tempo de sono é bastante reduzido e fica aquém do tempo que os trabalhadores sentem que necessitam dormir para se sentirem bem. O turno da tarde é o que permite os trabalhadores ficarem com um tempo de sono mais próximo desse “ideal”. Em relação à idade, todos os trabalhadores do grupo etário mais velho manifestam interrupções do sono diurno. Também se verifica um maior descontentamento destes trabalhadores com o tempo livre para realizar atividades que tragam bem-estar. Este estudo contribui para o conhecimento da realidade do trabalho por turnos na indústria e espera-se que desperte a procura de soluções que otimizem a vida destes trabalhadores.
