Kung slår dam : våldsforskningsmetodologi i ett våldsamt jämställt Sverige

King captures queen. Methodology in research on violence in violently equal Sweden Research and debate on violence against women in a Swedish context is here discussed from a perspective that focuses on the different understandings and epistemological claims behind existing positions. I crystallize a dominant perspective on violence, centred around fragmentation/deviance, and a challenging feminist understanding, centred around coherence/normality. I relate these understandings to a wider set of methodological choices and epistemological claims within research on violence against women, captured in what I call a discourse on partner violence (fragmentation) and a feminist discourse on men’s violence against women (coherence). The article also examines the reactions, in media and academic life, that a quantitative study on men’s violence against women in Sweden provoked, Captured queen, men’s violence against women in equal Sweden. A prevalence study (Lundgren et al 2001). By applying a coherent methodological approach, stemming from the feminist discourse on violence against women, the study seems to have placed itself outside what was comprehensible for many voices in the debate (from media and the academic field). I discuss the hostile reactions the study aroused, in relation to its methodology and the above presented conflicting understandings that occupy the research field “violence against women”.

Analysis an development of a prototype based on media wiki and semantic media wiki integrated with a design modeling that allows modeling of organizations based on demo

In a world where organizations are ever more complex the need for the knowledge of the organizational self is a growing necessity. The DEMO methodology sets a goal in achieving the specification of the organizational self capturing the essence of the organization in way independent of its implementation and also coherent, consistent, complete, modular and objective. But having such organization self notion is of little meaning if this notion is not shared by the organization actors. To achieve this goal in a society that has grown attached to technology and where time is of utmost importance, using a tool such as a semantic Wikipedia may be the perfect way of making the information accessible. However, to establish DEMO methodology in such platform there is a need to create bridges between its modeling components and semantic Wikipedia. It’s in that aspect that our thesis focuses, trying to establish and implement, using a study case, the principles of a way of transforming the DEMO methodology diagrams in comprehensive pages on semantic Wikipedia but keeping them as abstract as possible to allow expansibility and generalization to all diagrams without losing any valuable information so that, if that is the wish, those diagrams may be recreated from the semantic pages and make this process a full cycle.

O que tenho a ver com isso? aula-vivência sobre violência contra crianças e adolescentes

A violência constitui hoje a principal causa de morte em crianças de 5 a 19 anos, o que tem imposto aos profissionais de saúde um olhar mais atento a estas questões, bem como uma formação que busque compreender este fenômeno sobre os vários prismas que a circunscreve. O objetivo deste artigo é relatar a experiência vivenciada com alunos do curso de Graduação em Enfermagem da Universidade Federal do Rio Grande do Norte numa aula-vivência sobre esta temática. A aula foi baseada numa prática pedagógica de ação reflexiva. Desenvolveu-se a partir da integração dos conteúdos teóricos e práticos, articulando-os com temas sociais, políticos e econômicos. A aula foi dividida em três momentos: um momento de sensibilização; um segundo momento onde foi apresentado e discutido o arcabouço teórico, científico e legal que envolve o tema; e um terceiro, que visou estimular uma reflexão sobre a realidade vivenciada nos serviços de saúde por profissionais que atuam diante de situações de violência. Nos três momentos da aula pudemos proporcionar ao aluno a inquietação e a reflexão necessárias para pensarmos sobre a violência em toda a sua complexidade, pluricausalidade e com toda a carga de preconceito em que esta se encontra envolvida

Development of a new analytical approach based on cellulose membrane and chelator for differentiation of labile and inert metal species in aquatic systems

A new procedure was developed in this study, based on a system equipped with a cellulose membrane and a tetraethylenepentamine hexaacetate chelator (MD-TEPHA) for in situ characterization of the lability of metal species in aquatic systems. To this end, the DM-TEPHA system was prepared by adding TEPHA chelator to cellulose bags pre-purified with 1.0 mol L-1 of HCl and NaOH solutions. After the MD-TEPHA system was sealed, it was examined in the laboratory to evaluate the influence of complexation time (0-24 h), pH (3.0, 4.0, 5.0, 6.0 and 7.0), metal ions (Cu, Cd, Fe, Mn and Ni) and concentration of organic matter (15, 30 and 60 mg L-1) on the relative lability of metal species by TEPHA chelator. The results showed that Fe and Cu metals were complexed more slowly by TEPHA chelator in the MD-TEPHA system than were Cd, Ni and Mn in all pH used. It was also found that the pH strongly influences the process of metal complexation by the MD-TEPHA system. At all the pH levels, Cd, Mn and Ni showed greater complexation with TEPHA chelator (recovery of about 95-75%) than did Cu and Fe metals. Time also affects the lability of metal species complexed by aquatic humic substances (AHS); while Cd, Ni and Mn showed a faster kinetics, reaching equilibrium after about 100 min, and Cu and Fe approached equilibrium after 400 min. Increasing the AHS concentration decreases the lability of metal species by shifting the equilibrium to AHS-metal complexes. Our results indicate that the system under study offers an interesting alternative that can be applied to in situ experiments for differentiation of labile and inert metal species in aquatic systems.

Violência contra a mulher : estudo de caso em uma instituição de ensino

The study research case with a quantitative approach and prospective data, carried out between December 2010 and February 2011 with the aim of identifying the profile of women in the study, to characterize the acts of violence in the type, frequency, location occurrence and aggressor, analyze the steps taken after the occurrence of acts of violence and the main consequences on the victims. The population consisted of 285 workers in a tertiary institution in Rio Grande do Norte. The results showed that 99 (34.74%) have between 51 to 60 years of age, 78 (27.37%) of 41 to 50 and 62 (21.75%) between 20 and 30 years, are considered color white, 162 (56.84%) have completed higher education, 171 (60.00%) and of these 97 (56.73%) reported having some post-graduate degrees, are married, 141 (49.47%) and have from zero to one child, 148 (51.93%) reside in the south of the city of Natal, 146 (51.23%) have a monthly income of three to five minimum wages, 171 (60.00%) and are mostly in the Technical Administrative Sciences 152 (53.33%), 77 (27.02%) reported having experienced violence, 60 (62.50%) episodes of verbal aggression, 26 (27.08%) of bullying , 05 (5.21%) of physical abuse and 05 (5.21%) sexual harassment; 05 (100.00%) assaults were made by the spouse or partner of the victims and co-workers is another profession were responsible for 18 (30.00%) verbal aggression, 15 (57.69%) bullying and 03 (60.00%) sexual harassment, 02 (40.00%) of victims of physical aggression and 18 (30.00 %) of verbal abused only once, 10 (38.46%) of bullying and 02 (40.00%) of sexual harassment experienced four or more times 05 (100.00%) assaults occurred at domestic and work stood out with 36 (60.00%), verbal abuse, 22 (84.62%), moral harassment and 04 (80.00%) sexual harassment, 35 (36.46%) told colleagues work and 31 (32.29%) for family and friends in 75 (78.13%) cases there was no intervention, 07 (7.29) were unable to respond if something had been done and 14 (14.58% ) have been reported intervention of these, 09 (64.29%) were taken by the heads of the victims, 26 (32.10%) did not notify the fact on the ground that no action would be taken, 62 (80.52%) felt stress , 5 (1.76%) of women turned away from work after the episode of violence, accounting for 198 days of absenteeism. It is concluded that there is a high rate of violence against women, even when they have a good socioeconomic status, and in this sense is important to establish bases of new proposals for improving control of cases of health professionals, especially nurses, to approach patients with a more investigative, and that by identifying a case of violence, be instructed about the paths to be followed for notification while providing psychological support to victims.

Study of the interaction between cardiolipin bilayers and methylene blue in polymer-based Layer-by-Layer and Langmuir films applied as membrane mimetic systems

An increase of the reports involving mimetic systems has been observed. Briefly, these systems use biological phospholipids to exploit specific interactions between membrane-models and drugs. Here, the Layer-by-Layer (LbL) and Langmuir techniques were used to investigate the interaction between cardiolipin (CLP-negative phospholipid) and a cationic-like drug methylene blue (MB). Supported by a cationic polyelectrolyte (PAH), LbL films containing PAH/(CLP + MB) and PAH/(CLP + MB + AgNP) were grown up to 14 bilayers. The optical microscopy analysis revealed a decrease of the CLP vesicle sizes in the presence of MB as a possible consequence of the MB action onto the mechanical properties of the CLP membrane. From FTIR spectra, changes mainly related to peak position and band intensity and shape were observed in the spectra from PAH/CLP when in the presence of MB. The latter supports that the interactions between the phosphate and amine charged groups from CLP and PAH, respectively, established during the LbL film fabrication, besides the CLP hydrocarbon environment, are influenced by the presence of MB. Using the micro-Raman technique, a chemical mapping was build based on MB spectrum by resonance Raman scattering (RRS) and surface-enhanced resonance Raman scattering (SERRS). The later phenomenon was activated by Ag nanoparticles (AgNPs) trapped within the LbL film allowing collecting spectra for a single bilayer of PAH/(CLP + MB + AgNP). A rough estimation showed a SERRS amplification of 10(3) in comparison to RRS spectra. As a complementary approach, Langmuir films of CLP in the presence of co-spread MB were investigated through surface pressure vs mean molecular area (pi-A) isotherms. The results showed that for concentrations of MB below 100 mol%, the drug is expelled to water subphase for high values of surface pressure (condensed phase). For concentration at 100% and higher, the MB keeps bound to CLP floating monolayer. (C) 2010 Elsevier B.V. All rights reserved.

Structural integrity identification based on smart materials and neural networks

This paper presents a non-model based technique to detect, locate, and characterize structural damage by combining the impedance-based structural health monitoring technique with an artificial neural network. The impedance-based structural health monitoring technique, which utilizes the electromechanical coupling property of piezoelectric materials, has shown engineering feasibility in a variety of practical field applications. Relying on high frequency structural excitations (typically>30 kHz), this technique is very sensitive to minor structural changes in the near field of the piezoelectric sensors. In order to quantitatively assess the state of structures, two sets of artificial neural networks, which utilize measured electrical impedance signals for input patterns, were developed. By employing high frequency ranges and by incorporating neural network features, this technique is able to detect the damage in its early stage and to estimate the nature of damage without prior knowledge of the model of structures. The paper concludes with an experimental example, an investigation on a massive quarter scale model of a steel bridge section, in order to verify the performance of this proposed methodology.

Violência sexual intrafamiliar contra crianças e adolescentes: o estado da arte em periódicos em psicologia

Intrafamily sexual violence against children and adolescents is a highly complex and serious issue in terms of the damage caused to this population. However, despite the relevance of this discussion, the matter only began to be addressed in the second half of the twentieth century, with its inclusion in academic research from the perspective of damage caused to the victims. Debate on intrafamily sexual violence against children and adolescents has intensified in recent decades, particularly with the enactment of the Statute on Children and Adolescents (Federal Law 8069/90), which recognizes children and adolescents as rights holders. Open discussion on the issue meant several fields of knowledge began to study the topic. Particularly prominent among these areas is the field of Psychology, promoting theoretical discussions and practical interventions focusing on this type of violence. Given the theoretical and methodological diversity of psychological science and the many possibilities for the production of knowledge, this study aims to map and debate research conducted in the field that discusses intrafamily sexual violence against children and adolescents in Brazil. To that end, articles published in Psychology journals were analyzed. In order to achieve this objective, a search was conducted of Scielo Brasil using descriptors on the subject, chosen from a list reported by Faleiros (2000). The time frame studied was between 1990 and 2013, therefore included the date of the enactment of the Statute of Children and Adolescents. Qualitative analysis was selected as a data analysis technique around two main themes. The first involved analyzing the concept of intrafamily sexual violence based on its components. The second analytical theme addressed the theoretical and methodological strategies used by the authors. The aim was to identify and discuss the approaches chosen to achieve the proposed objectives as well as the justifications provided by the authors for their research. Analyses of these themes were based on theoretical discussions on intrafamily sexual violence against children and adolescents. Difficulties were identified in conceptualizing intrafamily sexual violence so as to include all its elements and differentiate it from sexual exploitation. The studies assessed showed substantial diversity in both the theoretical and methodological approaches used, contributing to understanding the phenomenon. It is expected that this study will contribute to reflection on intrafamily sexual violence against children and adolescents, promoting new studies and/or practical interventions
