Cuidar em oncologia na perspectiva de Alfred Schütz.

The study was realized among oncological nurses in their daily work routine and aimed to understand these professionals' subjective action, starting from their relation with patients, adopting a phenomenological reference framework based on the ideas of Alfred Schütz. The question: what does working in oncological care mean to you? Please describe, was used to collect statements, which were analyzed and clarified the typical action of a nurse caregiver in this daily routine. The study revealed that oncological care implies dealing with humans in a fragile situation; requires a relationship of affectivity; is care delivery that entails the genesis of professional burnout. Care delivery in oncology is highly complex, requiring a professional competence that goes beyond the technical-scientific sphere. Nursing professionals need to seek strategies which enable them to face the fatigue they are submitted to in their work.

Spinning Hopf solitons on S3 × ℝ

We consider a field theory with target space being the two dimensional sphere S2 and defined on the space-time S3 × . The Lagrangean is the square of the pull-back of the area form on S2. It is invariant under the conformal group SO(4,2) and the infinite dimensional group of area preserving diffeomorphisms of S2. We construct an infinite number of exact soliton solutions with non-trivial Hopf topological charges. The solutions spin with a frequency which is bounded above by a quantity proportional to the inverse of the radius of S3. The construction of the solutions is made possible by an ansatz which explores the conformal symmetry and a U(1) subgroup of the area preserving diffeomorphism group. © SISSA 2006.

Extrusão dos implantes em portadores de cavidade anoftálmica

Purpose: To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. Methods: A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the Faculdade de Medicina de Botucatu-UNESP. Results: Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye removed because of phthisis bulbi or trauma and the extrusion happened 1 or 2 years after the surgery. Extrusion was preceded by conjunctival dehiscence and exposure of the sphere and occurred with all used implants. Conclusion: Complications after orbital implant placement are a possibility. Dehiscence and sphere extrusion may happen and another surgery would be necessary. The patient and the ophthalmologist have to be prepared for this.

Global citizens or faraway viewers? São Paulo residents talk about the 2006 Lebanon conflict

As the emergence of a global public sphere becomes a possibility, growing out of denser economic, political and communicative networks as well as demanded by increasingly complex international problems, questions arise about the capacity and willingness of various national publics to engage in the global debate. This paper shows the results of a news reception analysis with the public of the city of São Paulo, Brazil during the months of July-November 2006, when the Lebanon conflict was broadly covered by the Brazilian media. The paper identifies the modes of engagement with the news about the international conflict, the types of reasoning used by these publics in interpreting the news, and the types of debates and conversations they have or don't have about the conflict. Special attention is given to the personal experience of learning about conflicts abroad and to the relationship between this experience and the construction of a new civic identity where participation in global affairs is an important element. The research shows that São Paulo residents are informed and care about international events, but to a large extent lack the resources and the spaces where they could reflect upon them. It also shows that young people tend to experience global events more intensely as part of their world than the general population. © 2008 Springer Science+Business Media, LLC.

A relação entre modernização neoliberal e práticas políticas atrasadas no Brasil dos anos 1990

Our goal is to investigate the reasons behind the presence of clientelist-type practices among the popular classes in Brazil, highlighting the decade of the 1990s. Our proposal gives salience to factors regarding the phenomenon's socio-political conjuncture, thereby taking us beyond explanations that rely exclusively on historical-cultural aspects or that sustain an economic bias. We use bibliographic and journalistic sources, from which we develop our own interpretation of the period. Thus, we observe that clientelist practices are encouraged to manifest themselves at the level of national political organization particularly within the federal sphere yet are also reflected at state and municipal levels, due to the coalition of political forces created through the implantation of a neoliberal project in Brazil. The latter has joined modern Brazilian social democracy and old regional oligarchies situated primarily within the PFL, PP, PTB and certain sectors of the PMDB, whose representatives are known for their attachment to patrimonialist and paternalistic practices. The inclusion of the latter in the conservative pact that has promoted neo-liberal political reform has thus meant awarding new value to such practices. Herein lies partial explanation for the vigor with which practices such as fisiologismo, apadrinhamento, abuse of state machinery, buying and selling of votes and clientelism have manifested themselves on the national scene over the course of the 1990s.

Interplanetary natural routes via Moon and Lagrangiam points L1 and L2

Swing-by techniques are extensively used in interplanetary missions to minimize fuel consumption and to raise payloads of spaceships. The effectiveness of this type of maneuver has been proven since the beginning of space exploration. According to this premise, we have explored the existence of a natural and direct links between low Earth orbits and the lunar sphere of influence, to obtain low-energy interplanetary trajectories through swing-bys with the Moon and the Earth. The existence of these links are related to a family of retrograde periodic orbits around the Lagrangian equilibrium point L1 predicted for the circular, planar, restricted three-body Earth-Moon-particle problem. The trajectories in these links are sensitive to small disturbances. This enables them to be conveniently diverted reducing so the cost of the swing-by maneuver. These maneuvers allow us a gain in energy sufficient for the trajectories to escape from the Earth-Moon system and to stabilize in heliocentric orbits between the Earth and Venus or Earth and Mars. On the other hand, still within the Earth sphere of influence, and taking advantage of the sensitivity of the trajectories, is possible to design other swing-bys with the Earth or Moon. This allows the trajectories to have larger reach, until they can reach the orbit of other planets as Venus and Mars.(3σ)Broucke, R.A., Periodic Orbits in the Restricted Three-Body Problem with Earth-Moon Masses, JPL Technical Report 32-1168, 1968.
