A percepção dos indivíduos sobre a inserção de tecnologias de informática nos processos de mudança organizacional: um estudo de caso

This dissertation presents a research aimed at identifying and explaining the individual perceptions as far as the introduction of computer technology concerning the organization change process and the reason underlying those changes, utilizing for study purposes, a customer attendance agency of INSS , located in São Luís-MA, which data collection was carried out by interviews with three managers and application of to thirty employees, all of them working at the unit researched. The core point was to identify feelings and perceptions of individuals, and the reason steering the change actions deployed in this office. Based on this perception, it is presented a literature review on the main thinkers who discussed the role, and the relevance of reasoning in the development of human relations, both in the organizations and in society. To start with, Max Weber thinking on rationality was introduced, on the sequence, the discussion raised by the Frankfurt School in its first phase, mainly on the Max Horkheimer thinking and finally it is shown a summary of Jurgen Habermas thinking, mainly concerning its communicative action theory proposed as a path to emancipation of individual of current instrumental reasoning. Summing up, we can conclude from this research that perceptions, feelings and opinions indicate that the institution uses to discuss with the civil servants the implementation of change process. For those servants the excessive functional control, the limitation of knowledge production and an artificial functional integration are consequences of the shape and intensity, as well as of computer technologies deployed in the institution. It is also shared by most of civil servants, including managers, that the overall participation would have more validity and would decrease the resistance to those changes. And it is also worth registering that despite of the servants having job stability, only 50% have positive expectations as far as its future in the institution.

Contribuição do design thinking para o processo de inovação de produtos

Este trabalho visa identificar práticas de design thinking (DT), isto é, as abordagens características da disciplina do design para criação de inovações, que possam ser incorporadas ao processo de desenvolvimento de novos produtos (DNP). Cinco dessas práticas – abordagem centrada em pessoas, estilo de trabalho colaborativo, pensar fazendo, visualização e combinação de abordagens divergente e convergente – foram analisadas por meio do estudo de caso em profundidade de três empresas polares: um escritório profissional de design, uma empresa de produtos para cuidados pessoais e um fabricante de ferramentas profissionais. A discussão teórica apoiou-se em autores de DNP e de DT que estudaram a evolução desses campos em gerações de maturidade, trazendo também visões bem recentes que apontam para a relevância das mudanças em curso. Entre os achados da pesquisa, observou-se que o modelo de gestão e a estrutura organizacional – orientada por projetos com times multifuncionais ou por processos com estrutura funcional – tem influência na adoção das práticas de DT. Outro achado, esse menos evidente, mostrou que a forma como a empresa se relaciona com clientes e usuários, guarda semelhança com a forma como trata seus profissionais de DNP. Uma descoberta interessante é a função moderadora do alinhamento de propósitos entre empresa e colaborador, para a adoção dessas práticas. Como contribuição ao campo de estudo, apresenta-se um diagrama de cinco gerações de evolução da oferta de novos produtos (ONP), termo utilizado para incorporar não só os produtos com inovações desenvolvidas e de propriedade da empresa focal, mas também aquelas desenvolvidas pelos próprios usuários e as inovações construídas nas redes sociais e oferecidas pela empresa focal.

Every day, they need courage and determination to adentrarem in mangrove cross functional seafood, which sold, ensure their survival. The life of catadoras seafood, fishing in mangrove and have your family's work, is the object of this study, through which search will be highlighted the history of women who perform a subsistence activity in your daily life. Will reflect on their work in the environment into which are entered, the vision that have labour, environment, family, sexuality, and their social relations. The research p Espírito Santo, in which these women, forgetting seafood calls, play activities diversified in its role of being a woman, reason personal awareness, generating an academic curiosity to know their life stories. Through ethnographic method, which spans observations, interviews, workshops and testimonials, we have tried to learn more about the daily life of forgetting seafood. This gives visibility to the human condition in one of its expressions which can help you understand and appreciate the cultural diversity of knowledge and knowledge constructed this activity pecheurfalco

HIGHER-DERIVATIVE SCHWINGER MODEL

Using the operator formalism, we obtain the bosonic representation for the free fermion field satisfying an equation of motion with higher-order derivatives. Then, we consider the operator solution of a generalized Schwinger model with higher-derivative coupling. Since the increasing of the derivative order implies the introduction of an equivalent number of extra fermionic degrees of freedom, the mass acquired by the gauge field is bigger than the one for the standard two-dimensional QED. An analysis of the problem from the functional integration point of view corroborates the findings of canonical quantization, and corrects certain results previously announced in the literature on the basis of Fujikawa's technique.

Multiloop amplitudes and vanishing theorems using the pure spinor formalism for the superstring

A ten-dimensional super-Poincaré covariant formalism for the superstring was recently developed which involves a BRST operator constructed from superspace matter variables and a pure spinor ghost variable. A super-Poincaré covariant prescription was defined for computing tree amplitudes and was shown to coincide with the standard RNS prescription. In this paper, picture-changing operators are used to define functional integration over the pure spinor ghosts and and to construct a suitable b ghost. A super-Poincaré covariant prescription is then given for the computation of N-point multiloop amplitudes. One can easily prove that massless N-point multiloop amplitudes vanish for N < 4, confirming the perturbative finiteness of superstring theory. One can also prove the Type IIB S-duality conjecture that R4 terms in the effective action receive no perturbative contributions above one loop. © SISSA/ISAS 2004.

Green teams: Understanding their roles in the environmental management of companies located in Brazil

Green teams are frequently considered in the state-of-the-art literature as an essential factor for companies aiming to implement and improve environmental management approaches and practices. However, most of the available literature on green teams is conceptual and theoretical by nature. Therefore, the main purpose of this article is to evaluate the main characteristics of green teams in Brazilian companies and to analyse the relationships between green teams and the maturity level of environmental management in those companies. Based on a conceptual background on corporate environmental management and green teams, a research was done in two complementary phases: a survey of 94 companies with ISO 14001 certification; and a multiple case study of four industrial companies. Survey results suggest that 82% of the studied companies have cross-functional green teams, i.e. involving various companies' departments; and 65% have functional green teams, i.e. individual department teams. The results of the case study suggest that the use of green teams is an instrument to the greening of companies with ISO 14001 in Brazil. The company with the most proactive and advanced environmental management is the same company which uses green teams more intensely. Green teams are especially necessary for implementing more technical environmental management practices, e.g. Life Cycle Assessment. Since this is one of the first studies analysing green teams, the results presented can be useful for companies and public policies aiming to implementation of environmental initiatives. © 2012 Elsevier Ltd.

A aglomeração urbana de Piracicaba: uma análise da integração funcional entre os municípios sob a ótica do movimento pendular

The growth area of cities has resulted in a phenomenon of conurbation (or expressing tendency). This correspond to a combine of two or more urban cores, there are formations of conurbations. In this way, there are the formations of urban concentrations and can achieve the step metropolitan or not metropolitan. Besides, this kind of expansion generates many social and environmental problems related about habitation, rubbish, drain, and others. Piracicaba, a city in expansion, recently, shows evidences of conurbation not metropolitan around itself. Like this, the paulista government, at June, 26 of 2012, institutionalized the Urban Concentration of Piracicaba, a regional unity, intending the administration along with 22 cities. However, for this fact, must be taken into account functional integration among urban centers, because the number of municipalities are presented to compose a urban concentration of level not metropolitan. It has checked along this research, according with proposition about 22 cities. Thus, the objective of this research is identify and analyze the functional integration among participating municipalities through the commuting, in other words, the spatial displacement of people, important factor to be taken into account when defining urban concentration. Considering the displacement routine people, the commuting, also aimed identify the flow of public transport intercity travel among the cities of Piracicaba Regional Unity. Then, analyze the criteria used for establish the Piracicaba Regional Unity, if it was considered technical character or if it was prioritized the political character. To conduct this research, it was done the literature review related to the theme and data collection related lines of intercity transportation and often travel with ARTESP and companies responsible for it service

Grafted neuronal precursor cells differentiate and integrate in injured hippocampus in experimental pneumococcal meningitis

Bacterial meningitis (BM) frequently causes persisting neurofunctional sequelae. Autopsy studies in patients dying from BM show characteristic apoptotic brain injury to the stem cell niche in the subgranular zone of the hippocampal dentate gyrus (DG), and this form of brain damage is associated with learning and memory deficits in experimental BM. With an eye to potential regenerative therapies, the survival, migration, and differentiation of neuronal precursor cells (NPCs) were evaluated after engraftment into the injured hippocampus in vitro and in vivo in an infant rat model of pneumococcal meningitis. Green fluorescent protein (GFP)-expressing NPCs were grafted into the DG of organotypic hippocampal slice cultures injured by challenge with live Streptococcus pneumoniae. Seven days after engraftment, NPCs had migrated from the site of injection into the injured granular layer of the DG and electro-functionally integrated into the hippocampal network. In vivo, GFP-expressing NPCs migrated within 1 week from the injection site in the hilus region to the injured granular layer of the hippocampal DG and showed neuronal differentiation at 2 and 4 weeks after transplantation. Hippocampal injury induced by BM guides grafted NPCs to the area of brain damage and provides a microenvironment for neuronal differentiation and functional integration.

BRAIN ACTIVATION AND CONNECTIVITY IN NON-DISABLED MULTIPLE SCLEROSIS PATIENTS

Multiple sclerosis (MS) is the most common demyelinating disease affecting the central nervous system. There is no cure for MS and current therapies have limited efficacy. While the majority of individuals with MS develop significant clinical disability, a subset experiences a disease course with minimal impairment even in the presence of significant apparent tissue damage on magnetic resonance imaging (MRI). The current studies combined functional MRI and diffusion tensor imaging (DTI) to elucidate brain mechanisms associated with lack of clinical disability in patients with MS. Recent evidence has implicated cortical reorganization as a mechanism to limit the clinical manifestation of the disease. Functional MRI was used to test the hypothesis that non-disabled MS patients (Expanded Disability Status Scale ≤ 1.5) show increased recruitment of cognitive control regions (dorsolateral prefrontal and anterior cingulate cortex) while performing sensory, motor and cognitive tasks. Compared to matched healthy controls, patients increased activation of cognitive control brain regions when performing non-dominant hand movements and the 2-back working memory task. Using dynamic causal modeling, we tested whether increased cognitive control recruitment is associated with alterations in connectivity in the working memory functional network. Patients exhibited similar network connectivity to that of control subjects when performing working memory tasks. We subsequently investigated the integrity of major white matter tracts to assess structural connectivity and its relation to activation and functional integration of the cognitive control system. Patients showed substantial alterations in callosal, inferior and posterior white matter tracts and less pronounced involvement of the corticospinal tracts and superior longitudinal fasciculi (SLF). Decreased structural integrity within the right SLF in patients was associated with decreased performance, and decreased activation and connectivity of the cognitive control system when performing working memory tasks. These studies suggest that patient with MS without clinical disability increase cognitive control system recruitment across functional domains and rely on preserved functional and structural connectivity of brain regions associated with this network. Moreover, the current studies show the usefulness of combining brain activation data from functional MRI and structural connectivity data from DTI to improve our understanding of brain adaptation mechanisms to neurological disease.

Sustainability principles put into practice: case studies of network analysis in Swiss climate change adaptation

Climate adaptation policies increasingly incorporate sustainability principles into their design and implementation. Since successful adaptation by means of adaptive capacity is recognized as being dependent upon progress toward sustainable development, policy design is increasingly characterized by the inclusion of state and non-state actors (horizontal actor integration), cross-sectoral collaboration, and inter-generational planning perspectives. Comparing four case studies in Swiss mountain regions, three located in the Upper Rhone region and one case from western Switzerland, we investigate how sustainability is put into practice. We argue that collaboration networks and sustainability perceptions matter when assessing the implementation of sustainability in local climate change adaptation. In other words, we suggest that adaptation is successful where sustainability perceptions translate into cross-sectoral integration and collaboration on the ground. Data about perceptions and network relations are assessed through surveys and treated via cluster and social network analysis.

Slow conduction in mixed cultured strands of primary ventricular cells and stem cell-derived cardiomyocytes

Modern concepts for the treatment of myocardial diseases focus on novel cell therapeutic strategies involving stem cell-derived cardiomyocytes (SCMs). However, functional integration of SCMs requires similar electrophysiological properties as primary cardiomyocytes (PCMs) and the ability to establish intercellular connections with host myocytes in order to contribute to the electrical and mechanical activity of the heart. The aim of this project was to investigate the properties of cardiac conduction in a co-culture approach using SCMs and PCMs in cultured cell strands. Murine embryonic SCMs were pooled with fetal ventricular cells and seeded in predefined proportions on microelectrode arrays to form patterned strands of mixed cells. Conduction velocity (CV) was measured during steady state pacing. SCM excitability was estimated from action potentials measured in single cells using the patch clamp technique. Experiments were complemented with computer simulations of conduction using a detailed model of cellular architecture in mixed cell strands. CV was significantly lower in strands composed purely of SCMs (5.5 ± 1.5 cm/s, n = 11) as compared to PCMs (34.9 ± 2.9 cm/s, n = 21) at similar refractoriness (100% SCMs: 122 ± 25 ms, n = 9; 100% PCMs: 139 ± 67 ms, n = 14). In mixed strands combining both cell types, CV was higher than in pure SCMs strands, but always lower than in 100% PCM strands. Computer simulations demonstrated that both intercellular coupling and electrical excitability limit CV. These data provide evidence that in cultures of murine ventricular cardiomyocytes, SCMs cannot restore CV to control levels resulting in slow conduction, which may lead to reentry circuits and arrhythmias.

Imaging neuroscience: Principles or maps?

This article reviews some recent trends in imaging neuroscience. A distinction is made between making maps of functional responses in the brain and discerning the rules or principles that underlie their organization. After considering developments in the characterization of brain imaging data, several examples are presented that highlight the context-sensitive nature of neuronal responses that we measure. These contexts can be endogenous and physiological, reflecting the fact that each cortical area, or neuronal population, expresses its dynamics in the context of interactions with other areas. Conversely, these contexts can be experimental or psychological and can have a profound effect on the regional effects elicited. In this review we consider experimental designs and analytic strategies that go beyond cognitive subtraction and speculate on how functional imaging can be used to address both the details and principles underlying functional integration and specialization in the brain.

The single market and competitiveness - the challenges for the Juncker team. CHALLENGE EUROPE Issue 22 - Challenges and new beginnings: Priorities for the EU's new leadership, September 2014

The announcement of the new European Commission is encouraging for single market supporters, especially in terms of how internal co-ordination and cross functional working will be organised. It is particularly significant that the responsibility for the single market in both goods and services is to be combined under one Commissioner portfolio. There is much to be gained from a combined focus, especially on enforcing the existing rules. A unified Consumer focus is also much welcomed. The European Parliament's Internal Market and Consumer Protection Committee (IMCO), which I had the privilege to Chair over the last five years, was extremely critical of the fragmented approach to consumer policy and legislation adopted by the outgoing Commission. A strong consumer focus underpins a dynamic and well-functioning market place and encourages more competition.
