The complex construction of psychological identities in Palestine: Integrating narratives and life experiences

Palestinian youth is challenged by multiple discourses in the process of constitution of its identity. This discursive multiplicity, characteristic of contemporary global societies, is confronted with personal life experiences, giving meaning to primarily nebulous affective impacts in the social environment. Starting from a semiotic-cultural perspective in cultural psychology one can establish a link between the notion of master narrative used by Hammack (2010) and the notion of myth-using the conception of ideology as a bridge that articulates both. Antinomies in the self-biographic narratives presented and discussed by Hammack (2010) support the master narrative of Palestinian identity and enter into interactions with other psychological identities of the interviewed youngsters, such as their religious tradition and secular education. Symbolic elements that are brought to the identity-making process by the diverse narratives are to be seen as resources for the comprehension of life experiences, demanding an integrative effort in the face of what is known and unknown in relation to alterity.

The production of critical-reflexive narratives and their effect on nursing students' portfolios

The objective of this study is to analyze the process of producing reflexive narratives on nursing students' portfolios. This qualitative study performed an analysis of the portfolios of the class discipline Health Promotion in Primary Education, taught in the fourth semester of the Nursing Licensure Course. Results showed an initial predominance of descriptive records, with the incipient approach of theoretical aspects associated with the aspects regarding their experience. Further, in the group and experience discussions, there were narratives containing more critical and reflexive elements, with justifications for the described actions and the relationships with the theoretical-practical aspects studied in the class and in the course. In conclusion, there is a process of producing critical-reflexive narratives in portfolios that could include a summarized description, using common sense and idealization which allows for including the differences and the theoretical review.

Therapeutic Project at Extra-Hospital Mental Health Services: a critical reflection on the elaboration and management of services' therapeutic projects

Based on a study conducted in Ribeirao Preto, SP, Brazil in extra-hospital mental health services that addressed the organization of these services, therapeutic projects and the inclusion of psychosocial rehabilitation in health actions available, a theoretical-critical reflection concerning the development process of the therapeutic projects by the services' teams is presented. The qualitative study was conducted in an outpatient clinic and a Psychosocial Care Center. Data were collected through semi-structured interviews and focal groups. Data analysis was based on the hermeneutic dialectic philosophy of Jurgen Habermas according to the techniques of reconstruction and interpretation. Data analysis revealed that professionals have difficulty developing and managing therapeutic projects. Health actions are made available without being concretely supported by a proposal guiding the service's practical activities. The therapeutic projects are referred by professionals as the result of guidelines provided by management levels or technical orientations inherent to each profession but not as an activity that represents a philosophy of work of the health team. When the therapeutic project is focused on as a type of consensus that results from a communicative action directed to a mutual and intersubjective understanding among the members of the mental health extra-hospital team, the difficulties of the services' team dialogically organizing themselves to collectively construct the therapeutic project is evidenced.

Preliminary Characterization of Novel Extra-cellular Lipase from Penicillium crustosum Under Solid-State Fermentation and its Potential Application for Triglycerides Hydrolysis

Current studies about lipase production involve the use of agro-industrial residues and newly isolated microorganisms aimed at increasing economic attractiveness of the process. Based on these aspects, the main objective of this work is to perform the partial characterization of enzymatic extracts produced by a newly isolated Penicillium crustosum in solid-state fermentation. Lipase extract presented optimal temperature and pH of 37 A degrees C and 9-10, respectively. The concentrated enzymatic extract showed more stability at 25 A degrees C and pH 7. The enzymes kept 100% of their enzymatic activity until 60 days of storage at 4 and -10 A degrees C. The stability under calcium salts indicated that the hydrolytic activity presented decay with the increase of calcium concentration. The specificity under several substrates indicated good enzyme activities in triglycerides from C4 to C18.

On reducing test length for FSMs with extra states

A long-standing problem when testing from a deterministic finite state machine is to guarantee full fault coverage even if the faults introduce extra states in the implementations. It is well known that such tests should include the sequences in a traversal set which contains all input sequences of length defined by the number of extra states. This paper suggests the SPY method, which helps reduce the length of tests by distributing sequences of the traversal set and reducing test branching. It is also demonstrated that an additional assumption about the implementation under test relaxes the requirement of the complete traversal set. The results of the experimental comparison of the proposed method with an existing method indicate that the resulting reduction can reach 40%. Experimental results suggest that the additional assumption about the implementation can help in further reducing the test suite length. Copyright (C) 2011 John Wiley & Sons, Ltd.

Depression in children and adolescents: family narratives in Brazilian primary attention

Background: The incidence of depression in children and adolescents still increasing and this disorder is now a major public health challenge worldwide. The Psychiatric Reform suggested an end to the fragmented and inefficient service by proposing integrated and quality care. In this context, family narratives are a way to recognize vulnerabilities and provide psychopathology prevention in primary care. Methods: Two medical databases (LILACS and SciELO) were surveyed and 14 texts published between 2004 and 2011 were selected and reviewed. Results and discussion: Children and adolescents are nowadays exposed to several stressing factors, in addition to natural vulnerabilities of this age group. Prevention is associated with a qualified hearing of family narratives in primary care and healthcare professionals should be able to perceive said and unsaid elements across the speech. Conclusion: In spite of the advances about children and adolescents mental health, some procedures must be adapted to achieve an efficient mental health policy though analyzing family discourse.

Plantar flexion force induced by amplitude-modulated tendon vibration and associated soleus V/F-waves as an evidence of a centrally-mediated mechanism contributing to extra torque generation in humans

Background: High-frequency trains of electrical stimulation applied over the human muscles can generate forces higher than would be expected by direct activation of motor axons, as evidenced by an unexpected relation between the stimuli and the evoked contractions, originating what has been called “extra forces”. This phenomenon has been thought to reflect nonlinear input/output neural properties such as plateau potential activation in motoneurons. However, more recent evidence has indicated that extra forces generated during electrical stimulation are mediated primarily, if not exclusively, by an intrinsic muscle property, and not from a central mechanism as previously thought. Given the inherent differences between electrical and vibratory stimuli, this study aimed to investigate: (a) whether the generation of vibration-induced muscle forces results in an unexpected relation between the stimuli and the evoked contractions (i.e. extra forces generation) and (b) whether these extra forces are accompanied by signs of a centrally-mediated mechanism or whether intrinsic muscle properties are the redominant mechanisms. Methods: Six subjects had their Achilles tendon stimulated by 100 Hz vibratory stimuli that linearly increased in amplitude (with a peak-to-peak displacement varying from 0 to 5 mm) for 10 seconds and then linearly decreased to zero for the next 10 seconds. As a measure of motoneuron excitability taken at different times during the vibratory stimulation, short-latency compound muscle action potentials (V/F-waves) were recorded in the soleus muscle in response to supramaximal nerve stimulation. Results: Plantar flexion torque and soleus V/F-wave amplitudes were increased in the second half of the stimulation in comparison with the first half. Conclusion: The present findings provide evidence that vibratory stimuli may trigger a centrally-mediated mechanism that contributes to the generation of extra torques. The vibration-induced increased motoneuron excitability (leading to increased torque generation) presumably activates spinal motoneurons following the size principle, which is a desirable feature for stimulation paradigms involved in rehabilitation programs and exercise training.

Projeto terapêutico nos serviços extra-hospitalares de saúde mental: uma reflexão crítica sobre a forma de elaboração e gestão dos projetos terapêuticos nos serviços

Com base em uma pesquisa realizada no município de Ribeirão Preto, SP, em serviços extra-hospitalares de saúde mental, que teve como objetivo estudar a organização desses serviços, os projetos terapêuticos e a inserção da reabilitação psicossocial nas ações de saúde disponibilizadas, apresenta-se reflexão teórico-crítica sobre o processo de elaboração dos projetos terapêuticos pelas equipes dos serviços. A pesquisa, que foi desenvolvida em um Ambulatório e em um Centro de Atenção Psicossocial II, foi realizada com base em metodologia qualitativa; como técnicas de coleta de dados, utilizou-se entrevistas semidiretivas e grupos focais, e a análise dos dados apoiou-se em referencial hermenêutico dialético de Jürgen Habermas, seguindo técnica interpretativa reconstrutiva. A análise dos dados mostrou que os profissionais têm apresentado dificuldade na elaboração e gestão dos projetos terapêuticos. Ações de saúde são disponibilizadas sem o referencial concreto de uma proposta norteadora das atividades práticas do serviço. Os projetos terapêuticos são referenciados pelos profissionais como decorrentes das diretrizes provenientes de instâncias gestoras ou das orientações técnicas próprias a cada categoria profissional, mas não como atividade de construção representativa de uma filosofia de trabalho da equipe de saúde. Ao enfocar-se o projeto terapêutico como um tipo de consenso fundado, resultante de ação comunicativa orientada para o entendimento mútuo e intersubjetivo entre membros da equipe do serviço extra-hospitalar de saúde mental, evidencia-se a dificuldade das equipes dos serviços em organizarem-se dialogicamente para a construção coletiva do projeto terapêutico.

Extra and intradural spinal Hemangioblastoma

Hemangioblastomas of the central nervous system (CNS) are low-grade highly vascularized tumors that may be sporadic or associated with Von Hippel-Lindau disease. Extradural hemangioblastomas are uncommon and those located extra and intradurally are even rarer. This study uses an illustrative case and literature review to discuss the difficulties to consider the correct diagnosis and to select the best surgical approach. A 57 years-old white male patient presented with myelopathy and right C5 radiculopathy. The images showed a lobulated, hourglass shaped, highly enhanced extra/intradural lesion that occupied the spinal canal and widened the C4-C5 right intervertebral foramen. Total resection of the intradural lesion was achieved through a posterior approach, but the extradural part could only be partially removed. Complete improvement was observed after four months of follow-up and the residual tumor has been followed up clinically and radiologically. Even though the preoperative impression was of a spinal schwannoma, the histopathological examination revealed grade I hemangioblastoma as per WHO. Despite their rarity, current complementary exams allow considering the diagnosis of hemangioblastoma preoperatively. That is essential to a better surgical planning in view of the particular surgical features of this lesion.
