Addressing the Negative Self-Concept in Posttraumatic Stress Disorder by a Three-Session Programme of Cognitive Restructuring and Imagery Modification (CRIM-PTSD): A Case Study  [PDF]
Meike Müller-Engelmann, Kerstin Hadouch, Regina Steil
Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.85020
Abstract: Background: Cognitive restructuring and imagery modification for posttraumatic stress disorder (CRIM-PTSD) is a new intervention that involves only three sessions and focuses on the self-concept. It combines cognitive restructuring of core trauma-related dysfunctional beliefs and mental imagery. The effectiveness of CRIM-PTSD has recently been demonstrated in a pilot study. Method: This article presents a step-by-step description of the administration of CRIM-PTSD in a female survivor of childhood sexual abuse (CSA) suffering from PTSD and major depressive disorder related to strong self-blame. Results: The intervention showed substantial reductions in PTSD symptoms and depression in the patient comparable to those observed in the pilot study. Conclusions: CRIM-PTSD might provide an economical tool for reducing PTSD symptoms when only a short time is available for intervention. Furthermore, this tool could be included in well-established PTSD treatments. In addition to the pilot study, a randomized controlled trial is needed to further explore the feasibility and effectiveness of this short intervention.
Regularization by Intrinsic Plasticity and Its Synergies with Recurrence for Random Projection Methods  [PDF]
Klaus Neumann, Christian Emmerich, Jochen J. Steil
Journal of Intelligent Learning Systems and Applications (JILSA) , 2012, DOI: 10.4236/jilsa.2012.43024
Abstract: Neural networks based on high-dimensional random feature generation have become popular under the notions extreme learning machine (ELM) and reservoir computing (RC). We provide an in-depth analysis of such networks with respect to feature selection, model complexity, and regularization. Starting from an ELM, we show how recurrent connections increase the effective complexity leading to reservoir networks. On the contrary, intrinsic plasticity (IP), a biologically inspired, unsupervised learning rule, acts as a task-specific feature regularizer, which tunes the effective model complexity. Combing both mechanisms in the framework of static reservoir computing, we achieve an excellent balance of feature complexity and regularization, which provides an impressive robustness to other model selection parameters like network size, initialization ranges, or the regularization parameter of the output learning. We demonstrate the advantages on several synthetic data as well as on benchmark tasks from the UCI repository providing practical insights how to use high-dimensional random networks for data processing.

Abstract: the relationship between pilgrimage and tourism is analyzed in this paper, based on field data collected at the religious shrine of bom jesus da lapa, in brazil. tourism and pilgrimage are understood here as categories that concentrate two meaning structures, or "ideal types" in a weberian sense, of what the true pilgrimage or what the true tourism would be. the hypothesis is that the pilgrimage, in its idealized sense, is linked to the emotional communitas model (victor turner; edith turner), while the category of tourism takes us to the societas model (norbert elias), characterized by its distant view and estrangement. the religious pilgrimage then is here understood as a meta social discourse that has within it two different forms of sociability, that operate based on opposing forms of thought: the logic of the communitas according to which true society would be expressed by the fraternal ideal of communion, and the logic of the societas, according to which distinction is the fundamental rule for society?s functioning.

Abstract: O presente trabalho aborda a rela o entre peregrina o e turismo, tomando como referência o material de campo coletado no santuário de Bom Jesus da Lapa, Brasil. Turismo e peregrina o s o tomados como categorias que condensam duas estruturas de significados, ou "tipos ideais", no sentido weberiano, do que seria a verdadeira peregrina o ou o turismo genuíno. Nossa hipótese é que, enquanto a peregrina o, em seu sentido idealizado, remete ao modelo emocional da communitas (Victor Turner; Edith Turner), o turismo conduz ao modelo da societas (Norbert Elias), marcada pelo olhar distanciado e de estranhamento. Tomamos, assim, a romaria como um discurso metassocial que comporta duas formas de sociabilidade, que operam a partir de lógicas opostas: a da communitas, para a qual a verdadeira sociedade seria expressa pelo ideal fraterno da comunh o, e a da societas, onde a regra básica de funcionamento da sociedade estaria na distin o.
Ecologia, corpo e espiritualidade: uma etnografia das experiências de caminhada ecológica em um grupo de ecoturistas

Caderno CRH , 2011, DOI: 10.1590/S0103-49792011000100003
Abstract: this paper aims to study the experience of the ecohikers, a group that go on ecological hikes, betting on the cultivation of a spiritual, mental and physical well-being, hikes amidst nature. from the ethnography of the experience of hikers, one aims to investigate the experience of the trails as places full of restoring forces, energetic fluids for the health of body and soul. based on the theoretical effort of a proposal that seeks, above all, to translate the phenomenology to the anthropological field and thus collapse dichotomies such as mind and body, nature and culture, subject and object, one tries to reflect on the therapeutic character of nature walks, understood by hikers not only as an exercise, but also as a means of access to matters of the soul.

English This research focuses empirically on the promotion of hiking events as Paraná state’s public policy. In this context, we have investigated the way in which the state’s action is related to a range of broader changes that have contributed to turn the environmental issue into a sort of language that is not restricted to the ecological realm, but is instead capable of functioning as a moral, ethic and aesthetic paradigm. In this sense, we are interested in both the institutionalization of environmental issues and in their accommodation with specific contexts of social relations. We have also examined state actions and their ability to coordinate economic development, ecology, family farming and tourism while promoting hiking events.Espa ol Este artículo tiene como interés empírico la promoción de caminatas en la naturaleza como política pública en el Estado del Paraná, Brasil.

Critical illness hyperglycemia: is failure of the beta-cell to meet extreme insulin demand indicative of dysfunction?
Garry M Steil, Michael SD Agus
Critical Care , 2009, DOI: 10.1186/cc7756
Abstract: In their study on hyperglycemia in critically ill children Preissig and Rigby [1] observed that children in the pediatric intensive care unit are unlikely to have critical illness hyperglycemia (CIH) in the absence of respiratory failure (RF) or cardiovascular failure (CVF) (0 of 12 patients studied), whereas those with RF but without CVF may (9 of 18) or may not (9 of 18), and virtually all patients with both RF and CVF do (10 of 11). The key observation was that the C-peptide level in children without CIH was similar for those with RF versus those without RF or CVF (2.3 versus 5.3 ng/ml), whereas in children with CIH, C-peptide was significantly higher with RF alone than with RF and CVF (11.5 versus 4.4 ng/ml; data reproduced in Figure 1). Importantly, the RF and CVF cohort uniformly received exogenous glucocorticoid therapy, unlike the other cohorts (100% versus 44% to 50%). The authors concluded from their data that elevated insulin resistance (high C-peptide) was the prominent cause of CIH in children with RF only, whereas beta-cell dysfunction (low C-peptide) was the primary cause in children with RF and CVF.We find the results very interesting but would take care in concluding that CIH in children with both RF and CVF is due primarily to a failure of the beta-cell. The beta-cell has a very complex response to hyperglycemia both acutely (first and second phase responses over just minutes [2,3]) and over the course of several days (increased mass [4,5]). Also, beta-cell exhaustion is a well known phenomenon characterized by an ability to increase secretion up to a certain level and thereafter fail in response to further demand [6,7]. Finally, exogenous glucocorticoid therapy, given to all patients with RF and CVF together, can also have complex interactions with insulin secretion, suppressing it in some in vitro studies [8,9] and enhancing it in other in vivo studies [10,11]. Support for these mechanisms playing a major role in CIH is variable, but there is ins

Abstract: the article aims at contributing to further the discussion about the quality of graduate programs of degree by research in this country, taking into account one of its constitutive elements: the viva voce. the viva is discussed in a theoretical manner through the systematized analysis of national and international studies related to the theme. firstly, the article discusses the purposes of master and doctorate programs, the objectives of the viva, its procedures and criteria, and then it points out its vulnerable aspects. the variables related to the subjectivity of the decision elements of each examiner are then analyzed, as well as the external influences surrounding the work of the examiners. in its conclusion the article indicates the high degree of heterogeneity associated to the knowledge and perception of the standards expected for the formation of a master or doctor, which influences systemically the process of the viva. lastly, the themes suggested for the continuity of this line of work aim at improving the consistency of the viva procedures, and at a more equitable assessment of the candidate, thereby contributing to improve the quality of graduate programs of degree by research.

Abstract: this paper analyses the reported results of an evaluation of the development process of master's level post-graduate distance education courses in production engineering. this initiative, the only one of its kind in brazil, won a quality award from the brazilian distance learning association (abed). this analysis involved three aspects evaluated in the report with respect to teachers' and students' attitudes toward distance learning: (a) teachers' and students' attitudes toward the quality of interaction; (b) students' attitudes toward the teacher's role; and (c) students' expectations regarding the course. the theoretical approach was the theory of attitudes, the concept of representative schemata, and the constructs relating to attitudes about different aspects of distance learning. this is an exploratory, quantitative study which analyzes the attitudes of teachers and students involved in a master's course in production engineering in a distance learning setting. we discuss how the students' attitudes influence the time they take to complete the course. the subjects of this survey are 471 students and 30 teachers. the data was collected from a questionnaire. our findings suggest that the students' and teachers' attitudes regarding the aspects investigated were predominantly positive. time to completion was about two years, which is less than the time consumed for a similar, traditional master's program offered by the same institution. unlike the findings of some surveys on the role of attitudes toward distance learning, the results of our study suggest that positive (or negative) attitudes toward distance learning involve both the pedagogical model and the technology employed. these findings beg a more detailed investigation about the role of students' attitudes in master's programs in production engineering.
