Fatores de risco cardiovascular em pessoas semabrigo e na população geral da cidade do Porto, Portugal

We described the distribution of risk factors for cardiovascular disease among homeless people living in the city of Porto, Portugal. Comparisons were made between subsamples of homeless people recruited in different settings and between the overall homeless sample group and a sample of the general population. All "houseless" individuals attending one of two homeless hostels or two institutions providing meal programs on specific days were invited to participate and were matched with subjects from the general population. We estimated sex, age and education-adjusted prevalence ratios or mean differences. The prevalence of previous illicit drug consumption and imprisonment was almost twice as high among the homeless from institutions providing meal programs. This group also showed lower mean systolic and diastolic blood pressure. Prevalence of smoking was almost 50% higher in the overall homeless group. Mean body mass index and waist circumference were also lower in the homeless group and its members were almost five times less likely to report dyslipidemia. Our findings contribute to defining priorities for interventions directed at this segment of society and to reducing inequalities in this extremely underprivileged populatio

Transforming musical performance: activating the audience as digital collaborators

Digital technologies have transformed the performance practice, recording and distribution technologies, economy and sonic landscape of music in a process of change that began in the early 1980s. Recent technological developments have opened up the possibility of embodied interaction between audiences and performers, reframing music performance as a collaborative improvisatory space that affords Interactive Musical Participation. The research in this practice-based thesis looks at the relationship and experience of audience members and musicians exploring Interactive Musical Participation within the wide stylistic framework of contemporary jazz. It also studies the potential for the creation of compositional, technological and performance protocols to enable successful Interactive Musical Participation. This has been achieved through a process of mapping the methodology behind the composition, technical infrastructure, performances and post-performance analysis of a series of musical artefacts. Cook (2001 and 2009) suggests that researchers in this field should “Make a piece, not an instrument or controller” and this dictum has influenced the development of the technical infrastructure for this research. Easily accessible and low-cost digital audio workstations Ableton Live (2017) and Logic Pro X (Apple, 2019) as well as the digital protocols Open Sound Control (OSC) (Opensoundcontrol.org) have been utilised to deliver the programming and networking requirements. A major innovation stemming from this project has been the development of the Deeper Love Soundpad App, a sample playback app for Apple smartphones and iPads, in collaboration with Dr. Rob Toulson. The theoretical background to this research has been informed by actornetwork theory, the sociological approach developed by Bruno Latour (2005), Michel Callon (1986) and John Law (1992). Actor-network theory (ANT) provides a framework for understanding the mechanics of power and organisation within heterogeneous non-hierarchical networks. Mapping and analysing the ANT networks and connections created by the research performances has provided valuable data in the Interactive Musical Participatio

STATE AND SOCIETY AT TEOTIHUACAN, MEXICO

Between 100 BCE and 200 CE, the city of Teotihuacan grew rapidly, most of the Basin of Mexico population was relocated in the city, immense civic-religious structures were built, and symbolic and material evidence shows the early importance of war. Rulers were probably able and powerful. Subsequently the city did not grow, and government may have become more collective, with significant constraints on rulers\u27 powers. A state religion centered on war and fertility deities presumably served elite interests, but civic consciousness may also have been encouraged. A female goddess was important but probably not as pervasive as has been suggested. Political control probably did not extend beyond central Mexico, except perhaps for some outposts, and the scale and significance of commerce are unclear. Teotihuacan\u27s prestige, however, spread widely in Mesoamerica, manifested especially in symbols of sacred war, used for their own ends by local elites
