Relação amorosa e tentativa de suicídio na adolescência : uma questão de (des)amor

Suicide rates have been rising all over the world. In Rio Grande do Norte state, a study carried out by Dutra (1999) investigated suicide rates among youngsters and found that in 1997 alone 244 cases of suicide attempt were registered. The author took an interest in studying this phenomenon among adolescents after reviewing Dutra s study and the technical literature on suicide. In addition to that, another topic caught her attention and raised new research questions: suicide attempts motivated by love, i.e., the end of a relationship, the fantasy of being abandoned by a partner. These have made the author to question how love manifested itself among adolescents and how it could become a reason for adolescents to give up their lives. Based on the data she analyzed and the research questions she developed, her research objective was to understand how adolescents who have attempted suicide because of love-related reasons have gone through this experience. The theoretical reference for the research was the Client-centered Therapy and more specifically, the construct self , according to Carl Rogers. The methodological strategy was inspired by the existential-phenomenological strategy. It used the narrative as a research instrument, inspired by the work of Walter Benjamim (1994) which was developed into a research strategy by Schmidt (1990). Four youngsters (three male and one female) have participated in this study. They have attempted suicide for love-related reasons during dolescence, when they were 12 to 18 years old. The interviews were recorded on cassette tapes, transcribed and literalized into narratives. The understanding of the narratives was based on the meanings that emerged from the youngsters speeches, as well as from the moments that touched the author. These moments highlighted the meaning of the experience of giving up life and the experience of love-based relationship as experienced by the youngsters. The study detected, among the adolescents who were interviewed, the existence of impulsiveness related to the suicide attempt. Also, the majority of the interviewees came from unstructured family backgrounds and had lost of one of their parents or had to face their parents divorce. The suicide was attempted by these youngsters through the ingestion of medicines. The research also revealed that the youngsters had regretted attempting suicide and felt guilty about it. With regards to their self-evaluation, the author observed that the youngsters had low self-esteem, negative perceptions about themselves and distorted views of themselves. These findings helped the author to reflect on the close relationship between the construct self and the suicide attempt. She also observed that a few factors, i.e., family context, education, social and cultural values, have influenced the way the youngsters perceived themselves . The results of this research confirm the idea that we have to understand the suicide attempt as a multi-determined phenomenon. This study contributed to the analysis and reflection on the factors that contribute to suicide attempts thus providing a foundation for the development of public health programs and policies to deal with this topic

Ensino Fundamental de 9 anos: estamos preparados para implantá-lo?

A revisão da história do desenvolvimento da educação brasileira ao longo do séc. XX permite-nos observar que grande parte das alternativas implantadas com o intuito de resolver os problemas de democratização, acesso e permanência do aluno em uma escola de qualidade foram suplantadas por políticas de caráter econômico e financeiro que acabavam preterindo os aspectos pedagógicos. Com base nesta constatação, entendemos que a atual proposição de ampliação do Ensino Fundamental de 8 para 9 anos representa uma nova oportunidade para a revisão deste procedimento histórico no âmbito da sociedade brasileira. Tendo em vista que o prazo proposto para adequação de todas as escolas à lei é 2010, realizou-se uma investigação junto a 2 (dois) Núcleos Regionais de Ensino, 8 (oito) Secretarias Municipais de Educação e 12 (doze) escolas vinculadas a estes órgãos, localizadas em diferentes cidades e regiões do estado do Paraná-Brasil, com o objetivo de investigar como a referida proposta chegou às escolas, bem como de que forma as mesmas estão se preparando para este processo. Para tanto, foram realizadas entrevistas junto a representantes dos núcleos e secretarias e também, junto aos diretores e professores das escolas. Pode-se constatar que muito pouco se sabe acerca da proposta de Implantação do Ensino Fundamental de 9 anos e que pairam muitas dúvidas e preocupações sobre se a proposta não consiste somente em mais uma mudança política e estrutural, se não significa, apenas, uma antecipação da alfabetização que poderá prejudicar as crianças. Assim sendo, parece ficar evidente a precocidade da implantação de forma ampla e generalizada, antes que sejam garantidas as condições de preparação das respectivas escolas e professores.

FROM DIRAC ACTION TO ELKO ACTION

A fundamental action, representing a mass dimension-transmuting operator between Dirac and ELKO spinor fields, is performed on the Dirac Lagrangian, in order to lead it into the ELKO Lagrangian. Such a dynamical transformation can be seen as a natural extension of the Standard Model that incorporates dark matter fields. The action of the mass dimension-transmuting operator on a Dirac spinor field, that de fines and introduces such a mapping, is shown to be a composition of the Dirac operator and the nonunitary transformation that maps Dirac spinor fields into ELKO spinor fields, de fined in J. Math. Phys. 4 8, 123517 (2007). This paper gives allowance for ELKO, as a candidate to describe dark matter, to be incorporated in the Standard Model. It is intended to present for the first time, up to our knowledge, the dynamical character of a mapping between Dirac and ELKO spinor fields, transmuting the mass dimension of spin one-half fermionic fields from 3/2 to 1 and from 1 to 3/2.

Phenomenology as a method to investigate the experience lived: a perspective from Husserl and Merleau Ponty's thought

Aim. By taking nursing as a human relationships activity, in spite of its strong technical-scientific features, this article reflects on the phenomenological method as one of the ways to develop ail investigation and acquire knowledge of the topic.Rationale. Based on Husserl's phenomenology, which is opposed to the way of doing science based on the laws that regulate the physics and mathematics, the article introduces Merleau Ponty's existential phenomenology as the theoretical foundation for the method it proposes. My existential conceptions-people as historic beings inserted in a world over which they act but which, in its turn, determines them; the human perception as reference for our way of being in the world; the space-time structure of perception-these are the key concepts that have led to the elaboration of ail approach to phenomenological research.Proposal of a methodology. Steps are proposed for such ail approach, namely phenomenological description, reduction and analysis. These lead to the building up of ideographic and nomothetic analyses, thus unveiling and describing general truths about the phenomenon studied. Finally, the possibilities for applying the methodology to nursing research are discussed, illustrated by my research into student nurses' perspectives on working oil an isolation ward.

Acupuntura e implante de fragmentos de ouro em pontos de acupuntura e pontos Acupuntura e implante de fragmentos de ouro em pontos de acupuntura e pontos gatilho para o tratamento de displasia coxo-femoral em Pastor Alemão

Background: Canine hip dysplasia (HD) is characterized by hip joint laxity and subluxation. It is the most common cause of osteoarthritis in dogs, especially in larger breeds. Its management includes nutritional supplements, nonsteroidal anti-inflammatory drugs, physical therapy, acupuncture or surgical procedures. Implantation of gold beads in acupuncture points and trigger points around a joint has been used in the treatment of osteoarthritis in dogs for at least 30 years. Gold bead implants(GBI) acts as continuous acupuncture stimulation and trigger point treatment in canine HD with long lasting results. Electrophysiological investigations of trigger points reveal dysfunctional muscle spindles which indicate that the electrical activity of active loci arises from extrafusal motor endplates.Case: This is a report on the use of acupuncture and GBI for bilateral HD in a nine year old female German Shepherd. The patient has a HD non-responsive to anti-inflammatory drugs and was unable to stand up or walk by its own. Radiographs showed marked dysplasia, significant subluxation with the femoral head partly out of a shallow acetabulum and massive secondary arthritic bone changes, mainly on the right side. The animal was submitted to eight acupuncture sessions with seven days interval. After the first acupuncture session the use of NSAID was interrupted. After eight weeks the dog was considered rehabilitated and underwent GBI in acupoints and trigger points as maintenance treatment. During the one-year follow-up period the improvement remained unchanged with no need of analgesics.Discussion: It has been suggested that acupuncture or GBI can treat the chronic pain resulting from osteoarthritis induced by HD. According to AP theory, GBI is permanent and long-lasting acupoint stimulation. Moreover, the method is inexpensive, quick and easy to perform, with no postoperative pain or need of exercise restriction. Although gold is extremely corrosion-resistant, the surface of the gold implants stimulates a reaction from the immune system causing an oxidative liberation of gold ions with anti-inflammatory actions. It is well known that gold ions are effective inhibitors of the respiratory burst of neutrophils and monocytes and the proliferation of lymphocytes. These findings suggest that gold implantation, on a local scale, mimics the anti-inflammatory and pain-relieving effect of drugs with chemically bound gold ions. The relatively slow speed of the process results in a limited liberation of gold ions securing that they are taken up almost exclusively by cells close to the implant. The nine year old female German shepherd had a positive response to acupuncture with pain relieve and locomotor rehabilitation. For the nine year old female German shepherd previous acupuncture sessions to GBI resulted in no post-implant worsening period. Indeed, the association acupuncture/GBI does not have the anti-inflammatory drugs undesirable effects and brings long lasting results. In conclusion, GBI therefore should be considered for canine HD when conservative or medical treatments fail to give the desired effect.

An effective wavelet method to detect and mitigate low-frequency multipath effects

To ensure high accuracy results from GPS relative positioning, the multipath effects have to be mitigated. Although the careful selection of antenna site and the use of especial antennas and receivers can minimize multipath, it cannot always be eliminated and frequently the residual multipath disturbance remains as the major error in GPS results. The high-frequency multipath from large delays can be attenuated by double difference (DD) denoising methods. But the low-frequency multipath from short delays is very difficult to be reduced or modeled. In this paper, it is proposed a method based on wavelet regression (WR), which can effectively detect and reduce the low-frequency multipath. The wavelet technique is firstly applied to decompose the DD residuals into the low-frequency bias and high-frequency noise components. The extracted bias components by WR are then directly applied to the DD observations to correct them from the trend. The remaining terms, largely characterized by the high-frequency measurement noise, are expected to give the best linear unbiased solutions from a least-squares (LS) adjustment. An experiment was carried out using objects placed close to the receiver antenna to cause, mainly, low-frequency multipath. The data were collected for two days to verify the multipath repeatability. The ground truth coordinates were computed with data collected in the absence of the reflector objects. The coordinates and ambiguity solution were compared with and without the multipath mitigation using WR. After mitigating the multipath, ambiguity resolution became more reliable and the coordinates were more accurate.
