The experience of identity transformation process for people living with tetraplegia and paraplegia = El proceso de reconstrucción de la identidad de las personas afectadas de una paraplejia o tetraplejia

A spinal cord injury (SCI) is perceived as a source of biographical disruption, not only at a physical level but also in terms of people’s life stories, their motivation and their self-esteem. The aim of this study is to explore the factors that people with spinal cord injuries perceive as contributing to rebuilding their sense of self. Two focus groups were established from the SCIcommunity, one of which was made up of 14 people with paraplegia and the other of 9 people with tetraplegia. In addition, four individual interviews were conducted with the participants. The results of content analysis show that the two most prominent factors in the process of identity renegotiation are the partial transformation of the subject’s identity followed by a coming to terms with that new identity. To rebuild self-worth, the importance of finding a balance between change and continuity was identified. Renegotiation of identity after a spinal cord injury is a complex phenomenon that greatly influences the SCI individual’s quality of life perceptions. Reaching a balance between the changes experienced due to the injury and finding a sense of continuity can be either facilitated or obstructed by the economic, political, legal, architectural, and social context

Fully smart cities: Analysis of the city to Smart City transformation process

Ever since the birth of the Smart City paradigm, a wide variety of initiatives have sprung up involving this phenomenon: best practices, projects, pilot projects, transformation plans, models, standards, indicators, measuring systems, etc. The question to ask, applicable to any government official, city planner or researcher, is whether this effect is being felt in how cities are transforming, or whether, in contrast, it is not very realistic to speak of cities imbued with this level of intelligence. Many cities are eager to define themselves as smart, but the variety, complexity and scope of the projects needed for this transformation indicate that the change process is longer than it seems. If our goal is to carry out a comparative analysis of this progress among cities by using the number of projects executed and their scope as a reference for the transformation, we could find such a task inconsequential due to the huge differences and characteristics that define a city. We believe that the subject needs simplification (simpler, more practical models) and a new approach. This paper presents a detailed analysis of the smart city transformation process in Spain and provides a support model that helps us understand the changes and the speed at which they are being implemented. To this end we define a set of elements of change called "transformation factors" that group a city's smartness into one of three levels (Low/Medium/Fully) and more homogeneously identify the level of advancement of this process. © 2016 IEEE.

Schistosoma mansoni: the effect of dexamethasone on the cercaria-schistosomulum transformation, in vivo

Treatment with dexamethasone (DMS) in the early phases of the experimental Schistosoma mansoni infection causes an indirect effect on the cercaria-schistosomulum transformation process. This is observed when naive albino mice are treated with that drug (50 mg/Kg, subcutaneously) and infected intraperitonealy 01 hour later with about 500 S. mansoni cercariae (LE strain). An inhibition in the host cell adhesion to the larvae, with a simultaneous delay in the cercaria-schistosomulum transformation, is observed. This effect is probably due to a blockade of the neutrophil migration to the peritoneal cavity of mice, by an impairment of the release of chemotactic substances. Such delay probably favors the killing of S. mansoni larvae, still in the transformation process, by the vertebrate host defenses, as the complement system.

Structural transformation in the product space: Patterns and implications

Product fundamentals are essential in explaining heterogeneity in the product space. The scope for adapting and transferring capabilities into the production of different goods determines the speed and intensity of the structural transformation process and entails dissimilar development opportunities for nations. Future specialization patterns become then partly determined by the current network of products’ relatedness. Building on previous literature, this paper explicitly compares methodological concepts of product connectivity to conclude in favor of the density measure we propose combined with the Revealed Relatedness Index (RRI) approach presented by Freitas and Salvado (2011). Overall, RRI specifications displayed more consistent behavior when different time horizons are equated.

Modelling the mechanical aspects of the curing process of magneto-sensitive elastomeric materials

In this paper, a phenomenologically motivated magneto-mechanically coupled finite strain elastic framework for simulating the curing process of polymers in the presence of a magnetic load is proposed. This approach is in line with previous works by Hossain and co-workers on finite strain curing modelling framework for the purely mechanical polymer curing (Hossain et al., 2009b). The proposed thermodynamically consistent approach is independent of any particular free energy function that may be used for the fully-cured magneto-sensitive polymer modelling, i.e. any phenomenological or micromechanical-inspired free energy can be inserted into the main modelling framework. For the fabrication of magneto-sensitive polymers, micron-size ferromagnetic particles are mixed with the liquid matrix material in the uncured stage. The particles align in a preferred direction with the application of a magnetic field during the curing process. The polymer curing process is a complex (visco) elastic process that transforms a fluid to a solid with time. Such transformation process is modelled by an appropriate constitutive relation which takes into account the temporal evolution of the material parameters appearing in a particular energy function. For demonstration in this work, a frequently used energy function is chosen, i.e. the classical Mooney-Rivlin free energy enhanced by coupling terms. Several representative numerical examples are demonstrated that prove the capability of our approach to correctly capture common features in polymers undergoing curing processes in the presence of a magneto-mechanical coupled load.

Transformation in teaching : listening to every voice

Action research is a methodology that supports practitioner research. This study is an exploration of one researcher's practice using the living-theory approach to action research. Initially, my focus was to improve my practice by asking how I can facilitate transformative learning experiences with the teachers with whom I work. As part of this search, I examined the contradictions between my espoused and implicit values. In keeping with the evolving nature of my inquiry, I unveiled the telos that constituted the impetus for my search, which began as a tension about the quality of my interactions and ended as a quest to find my voice among the others'. I used personal narratives, journal entries, a videotaping session, interactions with critical friends and interviews with colleagues and administrators to engage in a process of continuing self- and interactive reflection. Throughout my study, I explored how theoretical concepts intertwine with personal experiences. In the final chapter, I share the possible connections between my living educational theory and a more general theory of transformative learning. I conclude my study with a look at the transformation process I underwent as a result of the study and the new questions I formulated as I began the action research spiral again.

Theileria-induced leukocyte transformation

The intracellular protozoan parasites Theileria parva and T. annulata transform the cells they infect, inducing uncontrolled proliferation. This is not a trivial event as, in addition to permanently switching on the complex pathways that govern all steps of the cell cycle, the built-in apoptotic safety mechanisms that prevent 'illegitimate' cell replication also need to be inactivated. Recent experiments show that the NF-kappa B and phosphoinositide 3-kinase (PtdIns-3K) pathways are important participants in the transformation process. I kappa B kinase (IKK), a pivotal kinase complex in the NF-kappa B pathway, is recruited to the parasite surface where it becomes activated. The PtdIns-3K/Akt/PKB pathway is also constitutively activated in a parasite-dependent manner, but contrary to IKK, activation is probably not triggered by direct association with the parasite.

EPSTEIN-BARR VIRUS TRANSFORMATION OF B LYMPHOCYTE SUBPOPULATIONS

Epstein-Barr virus is a herpes virus distinguished by its remarkable specificity for the B lymphocyte of humans and certain other primates. Although the transformation process is very efficient, is has become clear that only a fraction of B lymphocytes is susceptible. Therefore the question may be raised if transformation is related to B cell stage of activation. B cells were purified from peripheral blood mononuclear cells by the removal of monocytes using elutriation and sheep red blood cell rosetting to remove T cells. Retesting B cells were purified using discontinuous Percoll gradients. Activation of resting cells for 24 hours with anti-mu or Staphylococcus aureus Cowan I (SAC) resulted in transition of susceptible cells into the G(,1) phase of the cell cycle as shown by an increase in cell size, an increase in uridine incorporation and an increase in sensitivity to B cell growth factor (BCGF). Entry into S phase was achieved by extending the period of activation to 48-96 hr as shown by an increase in thymidine incorporation. By this criterion, SAC activated cells entered S phase on day 2 and anti-mu treated cells on day 3. Control (G(,0)) cells and cells activated for varying lengths of time (G(,1), G(,1) plus S) were exposed to EBV and plated in a limiting dilution assay to determine the frequency of EBV-transformable cells. Control cells and cells activated for 24 hr had a precursor frequency of 1% to 2%. With continued activation, however, precursor frequency decreased as a function of the duration of activation. The decrease in frequency of transformable cells correlated with the entry of the population into S phase. The transformation frequency in the SAC-treated population was reduced twenty-fold on day 4, whereas in the anti-mu treated population it was reduced ten-fold. Treating cells with BCGF in conjunction with low concentrations of anti-mu decreased the transformation frequency to levels lower than anti-mu alone, further suggesting that entry into S phase is accompanied by a reduction in transformability. These results indicate that resting B cells are highly susceptible to transformation and that with in vitro activation into the cell cycle B cells become progressively insensitive to EBV. ^

Automatic compile-time parallelization of CLP programs by analysis and transformation to a concurrent constraint language.

The concept of independence has been recently generalized to the constraint logic programming (CLP) paradigm. Also, several abstract domains specifically designed for CLP languages, and whose information can be used to detect the generalized independence conditions, have been recently defined. As a result we are now in a position where automatic parallelization of CLP programs is feasible. In this paper we study the task of automatically parallelizing CLP programs based on such analyses, by transforming them to explicitly concurrent programs in our parallel CC platform (CIAO) as well as to AKL. We describe the analysis and transformation process, and study its efficiency, accuracy, and effectiveness in program parallelization. The information gathered by the analyzers is evaluated not only in terms of its accuracy, i.e. its ability to determine the actual dependencies among the program variables, but also of its effectiveness, measured in terms of code reduction in the resulting parallelized programs. Given that only a few abstract domains have been already defined for CLP, and that none of them were specifically designed for dependency detection, the aim of the evaluation is not only to asses the effectiveness of the available domains, but also to study what additional information it would be desirable to infer, and what domains would be appropriate for further improving the parallelization process.

p19Arf induces p53-dependent apoptosis during Abelson virus-mediated pre-B cell transformation

The Ink4a/Arf locus encodes p16Ink4a and p19Arf and is among the most frequently mutated tumor suppressor loci in human cancer. In mice, many of these effects appear to be mediated by interactions between p19Arf and the p53 tumor-suppressor protein. Because Tp53 mutations are a common feature of the multistep pre-B cell transformation process mediated by Abelson murine leukemia virus (Ab-MLV), we examined the possibility that proteins encoded by the Ink4a/Arf locus also play a role in Abelson virus transformation. Analyses of primary transformants revealed that both p16Ink4a and p19Arf are expressed in many of the cells as they emerge from the apoptotic crisis that characterizes the transformation process. Analyses of primary transformants from Ink4a/Arf null mice revealed that these cells bypassed crisis. Because expression of p19Arf but not p16 Ink4a induced apoptosis in Ab-MLV-transformed pre-B cells, p19Arf appears to be responsible for these events. Consistent with the link between p19Arf and p53, Ink4a/Arf expression correlates with or precedes the emergence of cells expressing mutant p53. These data demonstrate that p19Arf is an important part of the cellular defense mounted against transforming signals from the Abl oncoprotein and provide direct evidence that the p19Arf–p53 regulatory loop plays an important role in lymphoma induction.

The Western Balkans: deadlock in the EU enlargement process. OSW Commentary No. 43, 2010-11-24

On 9 November the European Commission presented the annual reports assessing the progress of the Balkans states in their preparations for EU membership, the enlargement strategy up to autumn 2011, and the assessment of the EU membership applications submitted by Albania and Macedonia. All these documents show that the reform process in the Balkan states has slowed down in comparison to previous years. The main reason for this slowdown is the negative consequences of the global economic crisis for these countries. Nonetheless, the transformation process is continuing, despite these difficulties. Another increasingly serious challenge for integrating the Balkan states is the EU's growing reluctance to enlarge any further. Among other measures, the EU states have blocked the formal acknowledgement of the integration progress (objections have been raised to the submission of membership applications by Albania, Serbia and Montenegro, and to granting Albania candidate status), which has significantly prolonged the accession process. In fact, this illustrates the lack of political will to accept new members. The European Commission is aware that the integration process may be blocked, and so in the coming year it is planning to focus on fostering the idea of enlargement among the EU member states. It will also focus on persuading the Balkan states to move on with reforms, especially those designed to strengthen state institutions (administration, the judiciary), even if their progress will not be formally considered during the integration process. The Commission assumes that by the end of next year, the reforms implemented by the Balkan states will be comprehensive enough to persuade the EU states to step up the integration process in subsequent years. However, if the EU member states' standpoint on the enlargement process does not change, the Commission's efforts will not bring about the expected results. Considering that their prospects for EU membership are receding, the Balkan states may not have sufficient motivation to go on with long-term reform efforts. As a result, the transformation process may become impeded, and in the longer perspective, the situation in the entire region may be destabilised.

Insights into the multistep transformation of MGUS to myeloma using microarray expression analysis.

To define specific pathways important in the multistep transformation process of normal plasma cells (PCs) to monoclonal gammopathy of uncertain significance (MGUS) and multiple myeloma (MM), we have applied microarray analysis to PCs from 5 healthy donors (N), 7 patients with MGUS, and 24 patients with newly diagnosed MM. Unsupervised hierarchical clustering using 125 genes with a large variation across all samples defined 2 groups: N and MGUS/MM. Supervised analysis identified 263 genes differentially expressed between N and MGUS and 380 genes differentially expressed between N and MM, 197 of which were also differentially regulated between N and MGUS. Only 74 genes were differentially expressed between MGUS and MM samples, indicating that the differences between MGUS and MM are smaller than those between N and MM or N and MGUS. Differentially expressed genes included oncogenes/tumor-suppressor genes (LAF4, RB1, and disabled homolog 2), cell-signaling genes (RAS family members, B-cell signaling and NF-kappaB genes), DNA-binding and transcription-factor genes (XBP1, zinc finger proteins, forkhead box, and ring finger proteins), and developmental genes (WNT and SHH pathways). Understanding the molecular pathogenesis of MM by gene expression profiling has demonstrated sequential genetic changes from N to malignant PCs and highlighted important pathways involved in the transformation of MGUS to MM.
