Impacto psicosocial de la tecnología de información y comunicación (tic): tecnoestrés, daños físicos y satisfacción laboral

Abstract: The introduction of information and communication technologies (ICT) in the organizations produced and still produces substantial changes in these structures at the modus operandi level and also with respect to the physical and psychological health of the workers using them. This phenomenon conditions the organizations’ operational skills, because it depends on the abilities, skills and capacities of the individuals who use these tools. Due to this relationship, the user might be at risk of a number of damages, such as anxiety, stress, depression and other psychosocial and physical disorders. Techno-stress is the concept that defines such illnesses. This study fits the concept. The research focused on a group of intensive users of a computer software manufacturing company in the area of security and defence, located in Portugal. It intends to acknowledge the psychosocial impact that ICT produce in these individuals. It also aims to verify to what extent the socio-demographic variables (gender, age, marital status, household composition, chores, and experience with computers) influence the levels of the existing techno-stress. The relationship between the level of techno-stress and professional satisfaction, as well as the factors which influence this relationship are also subject of this research. Key-words: techno-stress; psychosocial impact; ICT; professional satisfaction

Synthesis of Planar Arrays With Elements in Concentric Rings

Abstract: The circular symmetry of concentric ring arrays becomes an advantage for situations where the radiation patterns are symmetric in the azimuthal direction. For planar arrays with elements in an equispaced grid, the fast Fourier transform can be applied in the calculations involved between the array factor and the source distribution. However, for circular arrays the elements are in a non-equispaced grid, making the application of fast computation algorithms difficult. Therefore, two techniques are proposed to synthesize circular arrays. The first one provides the control of the pattern by sampling the array factor. In this case, the fast Fourier transform can be applied. The windows technique is also utilized to control the sidelobe levels and the ripple structure of the shaped beam. The second technique considers the symmetric nature of concentric circular arrays and the control of the array factor is performed imposing some specific points of the pattern.

Abstract: Scholarship on women in past societies has, in the last decades, worked to consolidate the subject, establishing its boundaries. Nevertheless, this field of research is far from being exhausted and its limits are still blurred. Therefore, the two books under review are welcome additions to the study of women in Rome, especially because both are intended for a lay or undergraduate reader. This is probably the mark that distinguishes these books from other volumes on the same topic. They are a good basis from which to start studying women in ancient Roman society and culture. Due to the lack of solid evidence concerning the multiple aspects of women’s life in Rome, what we do know is just a part of the whole picture. The historical record deals especially with the elites and with the abnormalities or eccentricities. Both MacL. and C. acknowledge this difficulty and strive to produce consistent and coherent perspectives on the subject. Both are admirable efforts aimed at introducing the appeal and the complexity inherent to the study of women’s lives in Rome to non-classicists. MacL., who published in 2012 a sourcebook on Women in Ancient Greece, here edits a comprehensive selection of texts in translation – historical, legendary, philosophical and inscriptional texts – arranged in five chronological parts: ‘Rome’s Beginnings’; ‘The Early and Middle Republic’; ‘The Late Republic’; ‘The Julio-Claudian Period’; and ‘The Later Empire’. Each of these sections is subdivided and each subdivision is organised according to specific topics (30 in all), some of them current issues of debate: women and the legendary past, Etruscan women, gender tensions, women in the inscriptional record, the female body, etc. An editor’s selection of texts is always debatable, but MacL.’s is consistent, covering the most important moments and characters in Roman history and including the core texts for the study of women in Rome. The materials are primarily literary and, due to the importance conceded to the great figures in legend and politics, mostly drawn from authors like Livy, Appian and Pliny. It is mostly complemented with inscriptions. This remark notwithstanding, MacL.’s volume offers a representative sample of passages that will be very useful in assessing both legendary and historical women and is a good teaching resource. This makes the book especially useful as a textbook for undergraduates, but it should be complemented by an instructor’s guidance. In fact, MacL.’s THE CLASSICAL REVIEW 193

Change, stability and prediction of gross motor co-ordination in portuguese children

Abstract: Background: The knowledge about intra- and inter-individual variation can stimulate attempts at description, interpretation and prediction of motor co-ordination (MC).Aim: To analyse change, stability and prediction of motor co-ordination (MC) in children.Subjects and methods: A total of 158 children, 83 boys and 75 girls, aged 6, 7 and 8 years, were evaluated in 2006 and re-evaluated in 2012 at 12, 13 and 14 years of age. MC was assessed through the Kiphard-Schilling's body co-ordination test and growth, skeletal maturity, physical fitness, fundamental motor skills (FMS), physical activity and socioeconomic status (SES) were measured and/or estimated.Results: Repeated-measures MANOVA indicated that there was a significant effect of group, sex and time on a linear combination of the MC tests. Univariate tests revealed that group 3 (8–14 years) scored significantly better than group 1 (6–12 years) in all MC tests and boys performed better than girls in hopping for height and moving sideways.
