Social dialogue, industrial relations and union revitalization in Argentina after 2003

After two decades of neoliberalism, Argentina goes through different transformations that reactivate the economy and generate a restruct uration process. At the same time, these transformations entail an institutional stren gthening: the best examples are labor institutions. This new context is characterized by an economic gr owth based on the domestic market and supported by several active wage policies withi n an employment recovering framework. All of which makes this context favorabl e for the resurgence of a central actor of industrial relations: the unions (Collier y Etchemendy, 2006, Senén y Medwid, 2007; Kelly y Frege, 2003) The resurrection of their actions becomes visible i n different ways: the institutional strengthening of the social dialogue, the recovery of the collective bargaining dynamism, as bipartite form of social dialogue, and the rise in labor conflict, as its opposite. In order to understand the reach of union revitaliz ation, especially regarding the collective bargaining, is necessary to consider as a starting point the social dialogue achievements. The aim of this paper is to think abo ut the space taken by the social dialogue in this new stage in Argentina, in which d evelopment has been fundamental the prominent role of the union actor and the State ac ive participation. In this paper we will analyze the period after 2003 in Argentina. Ho wever, we will refer to the 90s decade, necessarily attending to the comparison wit h another recent period of time. This paper is in line with the industrial relation discipline and tries to contribute with it. We took the strategic choice theories and the centr al question is: the social dialogue establishment depends on the socioeconomic and poli tical context in which is inserted or on the actors or on the interaction of both? (Th elen y Steinmo, 1992; Kochan, Katz y Mc. Kerise, 1994; Locke, Kochan, y Piore, 1995). For this, we will use data produced by the Ministry of Labor, Employment and Social Security (MTESS) that shows recent trends in terms of collective bargaining and labor conflict.

Improving the Multidisciplinary Treatment of Chronic Pain by Stimulating Body Awareness: A Cluster-randomized Trial

Background:Because of methodological flaws and a lack of theoretical foundation of body awareness (BA) in previous effect studies of interventions directed to stimulate BA, it is impossible to attribute treatment effects to this specific component of a multidisciplinary treatment. Therefore, this study evaluated short-term and long-term effects of a multidisciplinary pain rehabilitation program with and without psychomotor therapy (PMT), which focused on BA (measured by the scale of body connection) as a primary target of intervention. Methods:Ninety-four patients clustered in 20 treatment groups were cluster randomized, using a biased-coin design, to multidisciplinary treatment as usual with or without PMT. Outcome variables were health-related quality of life, disability, and depression. BA, catastrophizing, and self-efficacy were measured as potential process variables. Assessments were performed at baseline, directly after treatment, and at 3, 6, and 12 month follow-ups. The data were analyzed by linear mixed-model analysis according to the intention-to-treat principle. Results:Data of all 94 patients were used for analyses. After treatment, significant differences favoring PMT were found between conditions on depression (regression coefficient [RC]=−5.01; 95% confidence interval [CI], −8.81 to −1.21), BA (RC=0.23; 95% CI, 0.04 to 0.42) and catastrophizing (RC=−4.76; 95% CI, −8.03 to −1.48). These differences were no longer significant for depression at the 3-month follow-up and for catastrophizing at the 6-month follow-up. Conclusions:No clinical meaningful differences were found between treatment conditions in the primary outcome measures health-related quality of life and disability. However, this is the first long-term RCT that has shown that PMT improves BA in patients with chronic pain and shows good effect size and a significant decrease for catastrophizing.
Changes to the geometry and fluid mechanics of the carotid siphon in the pediatric Moyamoya disease

Abstract Background: The Moyamoya disease is a cerebrovascular disease that causes occlusion of the distal end of the internal carotid artery, leading to the formation of multiple tiny collateral arteries. To date, the pathogenesis of Moyamoya is unknown. Improved understanding of the changes to vascular geometry and fluid mechanics of the carotid siphon during disease may improve understanding of the pathogenesis, prognosis techniques and disease management. Methods: A retrospective analysis of Magnetic Resonance Angiography (MRA) images was performed for Moyamoya pediatric patients (MMD) (n = 23) and control (Ctrl) pediatric patients (n = 20). The Ctrl group was composed of patients who complained of headache and had normal MRA. We performed segmentation of MRA images to quantify geometric parameters of the artery. Computational fluid dynamics (CFD) was performed to quantify the hemodynamic parameters. Results: MMD internal carotid and carotid siphons were smaller in cross-sectional areas, and shorter in curved vascular length. Vascular curvature remained constant over age and vascular size and did not change between Ctrl and MMD, but MMD carotid siphon had lower tortuosity in the posterior bend, and higher torsion in the anterior bend. Wall shear stress and secondary flows were significantly lower in MMD, but the ratio of secondary flow kinetic energy to primary flow kinetic energy were similar between MMD and Ctrl. Conclusion: There were alterations to both the geometry and the flow mechanics of the carotid siphons of Moyamoya patients but it is unclear whether hemodynamics is the cause or the effect of morphological changes observed.
Predicting equity markets with social media and online news: using sentiment-driven Markov switching models.

Introduction There is substantial literature confirming the significance of irrationality on financial markets. One way of measuring this type of investor mood swings or noise trading is through sentiment analysis. Although traditionally published through consumer confidence indices, we provide 4 reasons to focus on sentiment derived from the internet specifically. One, mood analysis from large-scale online data is rapid and cost effective (Mao et al., 2011). Besides, there is no need to question the truthfulness or validity of respondents’ self-reported emotional states like in traditional surveys (Brener et al., 2003). Second, the World Wide Web contains massive amounts of inter-consumer communication that is accessed by everyone (Tirunillai and Tellis, 2012). The sample is thus likely to be larger and more representative. Third, digital media allow us to track the mood of millions in a more timely fashion, as in theory it could be derived every second. Fourth, social media’s forecast capabilities have already been demonstrated on a variety of socio-economic phenomena, including presidential elections (Tumasjan et al., 2010) and influenza epidemics (Culotta, 2010). However, previous studies often contain conflicting claims on the direction of the relationship between sentiment and stock returns. What they agree on is sentiment’s predictive relation with regard to volatility. For example, Antweiler and Frank (2004) scan messages in internet stock chat rooms for `buy’, `hold’ and `sell’ recommendations and find that message activity does not predict returns, but rather return volatility. Our model is therefore mostly focused on examining the predictive capabilities of digital By:
Distribution of Binding Sequences for the Mitochondrial Import Receptors Tom20, Tom22, and Tom70 in a Presequence-carrying Preprotein and a Non-cleavable Preprotein*

Preproteins destined for mitochondria either are synthesized with amino-terminal signal sequences, termed presequences, or possess internal targeting information within the protein. The preprotein translocase of the outer mitochondrial membrane (designated Tom) contains specific import receptors. The cytosolic domains of three import receptors, Tom20, Tom22, and Tom70, have been shown to interact with preproteins. Little is known about the internal targeting information in preproteins and the distribution of binding sequences for the three import receptors. We have studied the binding of the purified cytosolic domains of Tom20, Tom22, and Tom70 to cellulose-bound peptide scans derived from a presequence-carrying cleavable preprotein, cytochrome c oxidase subunit IV, and a non-cleavable preprotein with internal targeting information, the phosphate carrier. All three receptor domains are able to bind efficiently to linear 13-mer peptides, yet with different specificity. Tom20 preferentially binds to presequence segments of subunit IV. Tom22 binds to segments corresponding to the carboxyl-terminal part of the presequence and the amino-terminal part of the mature protein. Tom70 does not bind efficiently to any region of subunit IV. In contrast, Tom70 and Tom20 bind to multiple segments within the phosphate carrier, yet the amino-terminal region is excluded. Both charged and uncharged peptides derived from the phosphate carrier show specific binding properties for Tom70 and Tom20, indicating that charge is not a critical determinant of internal targeting sequences. This feature contrasts with the crucial role of positively charged amino acids in presequences. Our results demonstrate that linear peptide segments of preproteins can serve as binding sites for all three receptors with differential specificity and imply different mechanisms for translocation of cleavable and non-cleavable preproteins.
Tunable S-Band Q-Switched Fiber Laser Using Bi2Se3 as the Saturable Absorber

This paper describes a successful demonstration of S-band region wavelength output generated via a tunable Q-switch fiber laser with the topological insulator (TI) Bi2Se3 as a saturable absorber (SA). The modulation depth of the TI was measured as 11.1%, whereas the utilized 980-nm laser source operated at 100 mW pump power. By inserting the TI-SA between two ferrules and utilizing a tunable bandpass filter (TBPF), a stable and tunable Q-switching operation was achieved over the S-band wavelength region from 1493.6 to 1508.9 nm, wherein pulsewidth was 7.6 μs, and the tunable repetition rate ranged from 26.1 to 36.6 kHz. The Q-switched pulses had maximum pulse energy of 6.1 nJ, as measured from 2.5% of the cavity output. The results provide evidence that a TI-based SA is suitable for pulsed laser operation in the S-band wavelength region and offers potential for further development as an ultrabroadband photonics device.
Isolation and characterization of extragenic suppressors of mutations in the SSA hsp70 genes of Saccharomyces cerevisiae.

Saccharomyces cerevisiae strains that contain null alleles of two hsp70 genes, SSA1 and SSA2, are temperature sensitive for growth. In this study, extragenic suppressors of ssa1 ssa2 have been isolated. Suppression is due to mutations at nuclear loci designated EXA1, EXA2 and EXA3 for EXtragenic suppressor hsp70 subfamily A. Two of the four EXA1 alleles are dominant as is EXA3-1. The other two EXA1 alleles as well as the sole EXA2 allele are recessive. EXA1 mutations lead to accumulation of a previously uncharacterized form of hsp70. EXA2 and EXA3 mutations affect the regulation of the stress response. In exa2-1 ssa1 ssa2 strains the gene products of the remaining SSA hsp70 genes, SSA3 and SSA4 (Ssa3/4p), accumulate to higher levels. The EXA3-1 mutation results in increased accumulation of both Ssa3/4p and the hsp70s encoded by the SSB1 and SSB2 genes (Ssb1/2p), suggesting that the EXA3 gene product plays a central role in the yeast stress response. Consistent with this hypothesis, EXA3-1 is tightly linked to HSF1, the gene encoding the transcriptional regulatory protein known as "heat shock factor. " All of the genes identified in this study seem to be involved in regulating the expression of SSA3 and SSA4 or the activity of their protein products.
Integrating Multiple Experts for Correction Process in InteractiveRecommendation Systems

To improve the performance of the recommendation process, most of recommendation systems (RecSys) should collect better ratings from users. Particularly, rating process is an important task in interactive RecSys which can ask users to correct their own ratings. However, in real world, there are many inconsistencies (e.g., mistakes and missing values) or incorrect in the user ratings. Thereby, expert-based recommendation framework has been studied to select the most relevant experts in a certain item attribute (or value). This kind of RecSys can i) discover user preference and ii) determine a set of experts based on attribute and value of items. In this paper, we propose a consensual recommendation framework integrating multiple experts to conduct correction process. Since the ratings from experts are assumed to be reliable and correct, we first analyze user profile to determine the preference and find out a set of experts. Next, we measure a minimal inconsistency interval (MinIncInt) that might contain incorrect ratings. Finally, we propose solutions to correct the incorrect rating based on ratings from multiple experts.
Exploring the online communicative themes of child sex offenders

This exploratory study aimed to examine online communications between contact reality and non-contact fantasy child sex offenders (CSOs). This research wanted to ascertain whether it was possible to differentiate between these offenders based on the content of their online communications, something which has not previously been examined. The sample consisted of five contact reality and seven non-contact fantasy offenders, all convicted of a Child Sex Offence. Content analysis revealed 26 them. Results showed that non-contact fantasy offenders discussed Adult sexual relationships significantly more than contact reality offenders. All other comparisons were non-significant. The themes were then grouped into five higher order themes: (i) Adult relationships, (ii) Child sexual interest, (iii) Media, (iv) Sexual self, and (v) Rapport. The average largest proportion of the online communication related to Child sexual interest (34%) followed by Rapport (28%). There were no significant differences between the two types of offenders in relation to these five higher order themes. Explanations for the findings are discussed with implications for police investigations. Copyright © 2015 John Wiley & Sons, Ltd.
How stress alters neural systems of reinforcement: A model of depressive etiology

The primary goal of the proposed research is to identify how stress is internalized to affect cognitive functioning and increase the risk for Major Depressive Disorder (MDD). Dysfunctional stress reactivity has been proposed to be a risk factor for ongoing affective distress, yet mechanisms underlying this process remain unexplained. The medial prefrontal cortex (mPFC) has been implicated in the etiology of MDD, in the reactivity to stress, as well as in the adaptation of behavior to reinforcement. The combined activities of this particular neural system identify it as a focal node by which stress may be internalized to affect cognitive, emotional, and behavioral functioning. The experiments detailed here examined electroencephalographic (EEG) features that reflect cognitive control functions in the mPFC. Participants underwent EEG assessment as they completed a reinforcement (reward and punishment) learning task sensitive to mPFCbasal ganglia functioning, both with and without a laboratory stress manipulation. This experiment assessed how stress reactivity altered neural systems of reinforcement, and it contrasted these same factors with currently depressed individuals. In this series of investigations, we have identified a measure of how, and a possible mechanism by which, punishment information is internalized in stress reactivity and in the expression of MDD: error and punishment signals are increasingly coupled with the salience of “bad” outcomes. Stress-related alteration of reward and punishment learning systems – particularly in the mPFC is a viable candidate for how dysfunctional stress reactive responses are translated into ongoing cognitive and affective distress in depression.
Platelet-Derived Thrombospondin-1 Is Necessary for the Vitamin D-Binding Protein (Gc-Globulin) to Function as a Chemotactic Cofactor for C5a1

The chemotactic activity of C5a and C5a des Arg can be enhanced significantly by the vitamin D-binding protein (DBP), also known as Gc-globulin. DBP is a multifunctional 56-kDa plasma protein that binds and transports several diverse ligands. The objective of this study was to investigate the mechanisms by which DBP functions as a chemotactic cofactor for C5a using neutrophils and U937 cells transfected with the C5aR (U937-C5aR cells). The results demonstrate that U937-C5aR cells show C5a chemotactic enhancement only to DBP in serum, but, unlike mature neutrophils, this cell line cannot respond to DBP in plasma or to purified DBP. Analysis by SDS-PAGE and isoelectric focusing revealed no structural difference between DBP in serum compared with DBP in plasma. However, plasma supplemented with either serum, DBP-depleted serum, or activated platelet releasate provides a required factor and permits DBP to function as a chemotactic cofactor for C5a. Fractionation of activated platelet releasate revealed that the additional factor possessed the properties of thrombospondin-1 (TSP-1). Finally, purified TSP-1 alone could reproduce the effect of serum or platelet releasate, whereas Abs to TSP-1 could block these effects. These results provide clear evidence that TSP-1 is needed for DBP to function as a chemotactic cofactor for C5a.
PAS-mediated Dimerization of Soluble Guanylyl Cyclase Revealed by Signal Transduction Histidine Kinase Domain Crystal Structure*

Signal transduction histidine kinases (STHK) are key for sensing environmental stresses, crucial for cell survival, and attain their sensing ability using small molecule binding domains. The N-terminal domain in an STHK from Nostoc punctiforme is of unknown function yet is homologous to the central region in soluble guanylyl cyclase (sGC), the main receptor for nitric oxide (NO). This domain is termed H-NOXA (or H-NOBA) because it is often associated with the heme-nitric oxide/oxygen binding (H-NOX) domain. A structure-function approach was taken to investigate the role of H-NOXA in STHK and sGC. We report the 2.1Å resolution crystal structure of the dimerized H-NOXA domain of STHK, which reveals a Per-Arnt-Sim (PAS) fold. The H-NOXA monomers dimerize in a parallel arrangement juxtaposing their N-terminal helices and preceding residues. Such PAS dimerization is similar to that previously observed for EcDOS, AvNifL, and RmFixL. Deletion of 7 N-terminal residues affected dimer organization. Alanine scanning mutagenesis in sGC indicates that the H-NOXA domains of sGC could adopt a similar dimer organization. Although most putative interface mutations did decrease sGCβ1 H-NOXA homodimerization, heterodimerization of full-length heterodimeric sGC was mostly unaffected, likely due to the additional dimerization contacts of sGC in the coiled-coil and catalytic domains. Exceptions are mutations sGCα1 F285A and sGCβ1 F217A, which each caused a drastic drop in NO stimulated activity, and mutations sGCα1 Q368A and sGCβ1 Q309A, which resulted in both a complete lack of activity and heterodimerization. Our structural and mutational results provide new insights into sGC and STHK dimerization and overall architecture.
Cerebral MRI findings and cognitive functioning

Objective: To examine the association between prevalent cerebral abnormalities identified on MRI and cognitive functioning in a predominantly middle-aged, population-based study cohort. Methods: Cerebral MRI was performed on 1,538 individuals (aged 55 to 72) from the Atherosclerosis Risk in Communities (ARIC) cohort, with no history of stroke or TIA, at study sites in Forsyth County, NC, and Jackson, MS. White matter hyperintensities (WMHs), ventricular size, and sulcal size were graded by trained neuroradiologists on a semiquantitative, 10-point scale. Cognitive functioning was assessed using the Delayed Word Recall Test (DWRT), Digit Symbol Substitution Test (DSST), and Word Fluency Test (WFT). Results: High ventricular grade was independently associated with significantly lower scores on the DWRT and DSST and greater risk (odds ratio [OR] 2.32, 95% confidence interval [CI] 1.51 to 3.56) of impaired scores (i.e., ≤10th percentile) on the DWRT. High sulcal grade was associated with a modest decrement in scores on the DWRT. The presence of coexisting high grade WMHs and silent infarcts was independently associated with lower scores on all cognitive tests and greater risk of impaired functioning on the DSST (OR 2.91, 95% CI: 1.23 to 6.89) and WFT (OR 2.28, 95% CI 1.03 to 5.08). The presence of two or more high-grade abnormalities was associated with increased risk of impaired functioning on all cognitive tests (DWRT: OR 2.23, 95% CI 1.40 to 3.55; DSST: OR 2.06, 95% CI 1.13 to 3.76; WFT: OR 2.07, 95% CI 1.23 to 3.49) independent of multiple covariates and silent infarcts. Conclusion: Common changes in brain morphology are associated with diminished cognitive functioning in middle-aged and young-elderly individuals.
Memorial meshwork: The making of the commemorative space of the Hyde Park 7/7 Memorial

How do memorials act to transmit memory through the organization of space? In this article, we contrast a ‘preservation’ model of the endurance of encoded memory with a ‘meshwork’ model which treats memory as emergent on the perdurance of the memorial site. Developing a theoretical framework from Tim Ingold’s work, we describe how memorialization receives its spatial form through a collective work of braiding together multiple threads of activities and material flows. To illustrate, we examine the spatial and temporal organization of the Hyde Park 7/7 memorial from its initial designs, through to installation and contemporary use. We draw on interview data featuring various stakeholders in the 7/7 memorial project to analyse the relationship between memorial space and material relations. We develop an approach to organizational space as an unfinished meshwork that folds together wanted and unwanted memory, making the historical a matter of ongoing live concern but with the absence of a permanent guiding narrative.
