An overwhelming amount of evidence now suggests that some people are becoming overloaded with neurotoxins. This is mainly from changes in their living environment and style, coupled with the fact that all people are different and display a broad distribution of genetic susceptibilities. It is important for individuals to know where they lie concerning their ability to either reject or retain toxins. Everyone is contaminated with a certain baseline of toxins that are alien to the body, namely aluminum, arsenic, lead, and mercury. Major societal changes have modified their intake, such as vaccines in enhanced inoculation procedures and the addition of sushi into diets, coupled with the ever-present lead, arsenic, and traces of manganese. It is now apparent that no single toxin is responsible for the current neurological epidemics, but rather a collaborative interaction with possible synergistic components. Selenium, although also a neurotoxin if in an excessive amount, is always present and is generally more present than other toxins. It performs as the body’s natural chelator. However, it is possible that the formation rates of active selenium proteins may become overburdened by other toxins. Every person is different and it now appears imperative that the medical profession establish an individual’s neurotoxicity baseline. Moreover, young women should certainly establish their baselines long before pregnancy in order to identify possible risk factors.

In this paper, we present a system that allows a user with a head-mounted display (HMD) to communicate and collaborate with spectators outside of the headset. We evaluate its impact on task performance, immersion, and collaborative interaction. Our solution targets scenarios like live presentations or multi-user collaborative systems, where it is not convenient to develop a VR multiplayer experience and supply each user (and spectator) with an HMD. The spectator views the virtual world on a large-scale tiled video wall and is given the ability to control the orientation of their own virtual camera. This allows spectators to stay focused on the immersed user's point of view or freely look around the environment. To improve collaboration between users, we implemented a pointing system where a spectator can point at objects on the screen, which maps an indicator directly onto the objects in the virtual world. We conducted a user study to investigate the influence of rotational camera decoupling and pointing gestures in the context of HMD-immersed and non-immersed users utilizing a large-scale display. Our results indicate that camera decoupling and pointing positively impacts collaboration. A decoupled view is preferable in situations where both users need to indicate objects of interest in the scene, such as presentations and joint-task scenarios, as it requires a shared reference space. A coupled view, on the other hand, is preferable in synchronous interactions such as remote-assistant scenarios.

The aim of this study was to explore how teachers and parents experience and reflect on participation and interaction with and between less active fifth-grade pupils in physically active academic lessons, in the school playground and during physical activity homework. This study formed part of the Active Smarter Kids study investigating the effects of daily physical activity on academic performance and health, and generated qualitative data from focus group interviews with teachers and parents. We identified three main themes: (1) aiming at and planning for interaction – a critical prerequisite for learning; (2) negotiating collaborative interaction during activities at school; and (3) facilitating physical activity at home through collaboration. The promotion of collaborative interaction appeared as a powerful means of facilitating learning in physically active academic lessons at school and at home for less active pupils.

Complex behaviors are layered with processes across timescales that must be coordinated with each other to accomplish cooperative goals. Complexity matching is the coordination of nested layers of behaviors across individuals. We hypothesize that complexity matching extends across individuals and their respective layers of processes when cooperating in joint tasks. We measured coordination in a joint tower building task through the layers of sound and movement patterns produced by partners and found that partners built higher towers when their sound patterns fell into more similar relations with each other across timescales, as measured by complexity matching. Our findings shed light on the function of complexity matching and lead to new hypotheses about multiscale coordination and communication. We discuss how complexity matching encompasses flexible and complementary dynamics between partners that support complex acts of human coordination.

ABSTRACTDigital information provided easy access to many different scenarios and types of knowledge, besides strengthe-ning of media that survives independently managed, where technologies leverage the collective professional experience and techniques with funding from ‘new tools’ and society connected , as is the case of crowdfunding. This perspective of journa-lism that involves collaborative and financial participation of people, the brazilian case of ‘Agência Pública’ uses crowdfun-ding to promote investigative reporting and is the first project to use this strategy in Brazil. This paper relates the project with histories situations about associativism.RESUMOA informação digitalizada proporcionou um fortalecimento dos meios de comunicação que sobrevivem de gestão independente, onde tecnologias potencializam a atuação profissional e financiamento coletivo com técnicas provenientes de novas ferramentas e da sociedade conectada, como é o caso do crowdfunding. Nesta perspectiva de um jornalismo que envolve a participação de pessoas, a Agência Pública utiliza o crowdfunding para fomento de realização de reportagens investigativas e é o primeiro projeto jornalístico a utilizar tal estratégia no Brasil. O estudo relaciona o caso da Agência com experiências históricas, que já trabalhavam com associativismo.
