The Subject Position in Brazilian Portuguese: the Embedding of a Syntactic Change
One remarkable difference between European and Brazilian Portuguese is related with the setting of the Null Subject Parameter (NSP). While European Portuguese (EP) behaves like a prototypical romance null subject language, contemporary Brazilian Portuguese (BP) is a partially pro-drop system (Duarte 1995; Kato 2000), with preferably overt referential subjects and null expletive subjects in finite clauses, a procedure consistent with a discourse orientation shown by BP (Kato and Duarte 2003).
The aim of this paper is to show that the subject position of non-finite clauses begins to show some âside effectsâ or âby-productsâ of the ongoing process of change. Our analysis will compare the position of arbitrary subjects of infinitival sentences in EP and BP inspired by the diachronic analysis of Cavalcante (2006) of such structures in Classical Portuguese (from the 16th to the 18th century) and Modern European Portuguese (19th century). According to Cavalcanteâs analysis, the use of impersonal clitic SE in variation with a null arbitrary subject in infinitival sentences declines from 20% in Classical Portuguese to 10% in Modern European Portuguese. The examples below illustrate the possible representations of the arbitrary âexternal argumentâ of the infinitive:
EXAMPLE (1a-c)
(1a) illustrates the empty subject; in (1b), the clitic SE could be interpreted as a nominative SE and in (1c), as a passive SE, since the inflected infinitive agrees with the internal argument of abreviar (to shorten). In each case, however, the external argument is suspended and has arbitrary interpretation. The same patterns can be found with tough-movement constructions. In this paper we compare contemporary Brazilian and European Portuguese, using samples from speech and writing. The results for the speech samples reveal that (a) EP exhibits the same pattern observed in the 19th century data (an average of 8% of clitic se); (b) BP, on the other hand, shows an increasing tendency to use overt subjects, specially the nominative pronoun vocĂȘ (you) in variation with impersonal clitic SE, some of the strategies used for arbitrary reference in finite clauses (Kato & Tarallo 1986; Duarte, Barbosa & Kato 2001 among others), a clear evidence of the embedding of the process of change in progress:
EXAMPLE (2)
As for the written language, a more similar behavior is found for both varieties. Since Brazilian traditional grammars have been built according to the 19th century EP, the rates of clitic SE are close to the ones found for Modern and Contemporary EP and the use of nominative pronouns is extremely rare. A qualitative analysis of se-constructions shows, however, that in EP, the clitic assures an arbitrary reading of the infinitival subject; in BP, on the other hand, such a constraint does not apply

Magnetoresistive detection of perpendicular switching in a magnetic insulator
Spintronics offers promising routes for efficient memory, logic, and
computing technologies. The central challenge in spintronics is electrically
manipulating and detecting magnetic states in devices. The electrical control
of magnetization via spin-orbit torques is effective in both conducting and
insulating magnetic layers. However, the electrical readout of magnetization in
the latter is inherently difficult, limiting its use in practical applications.
Here, we demonstrate magnetoresistive detection of perpendicular magnetization
reversal in an electrically insulating ferrimagnet, terbium iron garnet (TbIG).
To do so, we use TbIG|Cu|TbCo, where TbCo is a conducting ferrimagnet and
serves as the reference layer, and Cu is a nonmagnetic spacer. Current
injection through Cu|TbCo allows us to detect the magnetization reversal of
TbIG with a simple resistance readout during an external magnetic field sweep.
By examining the effect of measurement temperature, TbCo composition, and Cu
thickness on the sign and amplitude of the magnetoresistance, we conclude that
the spin-dependent electron scattering at the TbIG|Cu interface is the
underlying cause. Technologically-feasible magnetoresistive detection of
perpendicular switching in a ferrimagnetic garnet is a breakthrough, as it
opens broad avenues for novel insulating spintronic devices and concepts
Chemical and isotopic snow variability in East Antarctica along the 2001/02 ITASE traverse
AbstractAs part of the International Trans-Antarctic Scientific Expedition (ITASE) project, a traverse was carried out from November 2001 to January 2002 through Terre AdĂ©lie, George V Land, Oates Land and northern Victoria Land, for a total length of about 1875 km. The research goal is to determine the latitudinal and longitudinal variability of physical, chemical and isotopic parameters along three transects: one westâeast transect (WE), following the 2150m contour line (about 400 km inland of the AdĂ©lie, George V and Oates coasts), and two northâsouth transects (inland Terre AdĂ©lie and Oates CoastâTalos DomeâVictoria Land). The intersection between the WE and Oates CoastâVictoria Land transects is in the Talos Dome area. Along the traverse, eight 2 m deep snow pits were dug and sampled with a 2.5 cm depth resolution. For spatial variability, 1 m deep integrated samples were collected every 5 km (363 sampling sites). In the snow-pit stratigraphy, pronounced annual cycles, with summer maxima, were observed for nssSO42â, MSA, NO3â and H2O2. The seasonality of these chemical trace species was used in combination with stable-isotope stratigraphy to derive reliable and temporally representative snow-accumulation rates. The study of chemical, isotopic and accumulation-rate variability allowed the identification of a distribution pattern which is controlled not only by altitude and distance from the sea, but also by the complex circulation of air masses in the study area. In particular, although the Talos Dome area is almost equidistant from the Southern Ocean and the Ross Sea, local atmospheric circulation is such that the area is strongly affected only by the Ross Sea. Moreover, we observed a decrease in concentration of aerosol components in the central portion of the WE transect and in the southern portion of the Talos Dome transect; this decrease was linked to the higher stability of atmospheric pressure due to the channelling of katabatic winds
Researchers' Seedbeds for the Development of Research Skills in Universities
The objective of this study is to demonstrate the effects of the application of the pedagogical strategy "researcher's seedbed" in the development of research skills in universities. This research is of quasi-experimental, longitudinal and prospective design, where 2 groups were formed: control and experimental, of 18 students each. A validated instrument was used to measure the research competences, as well as a rubric for the evaluation of the research projects. It began with a pre-test, and after 14 weeks of the development of the strategy, through different educational sessions, the post-test was administered. Likewise, the research projects carried out were evaluated. The results obtained showed that the pedagogical strategy had a positive effect on the development of research skills, with the highest evaluation being found in 40% of the students, with statistically significant differences between the control and experimental groups (Mann Whitney U, p=0.007), and between the pre-test and post-test (Wilcoxon, p=0.00). In the development of cognitive and procedural competence, an effect was also found in the strategy, but not in the attitudinal competence (Mann Whitney U, p=0.496). The application of this study is based on the fact that the formation of research groups in universities strengthens formative research in higher level students. This study shows the benefits of the implementation of strategies for the development of research competencies, since the product will be to train professionals with a scientific culture in favor of society
A multipronged approach to understanding the form and function of hStaufen protein
Staufen is a dsRNA binding protein that plays an essential role in many aspects of RNA regulation, such as mRNA transport, Staufen-mediated mRNA decay and the regulation of mRNA translation. Staufen is a modular protein characterized by the presence of conserved consensus amino acid sequences that fold into double-stranded RNA binding domains (RBDs) as well as degenerated RBDs that maintain the α-ÎČ-ÎČ-ÎČ-α fold but are unable to bind RNA and are instead involved in protein-protein interactions. The variety of biological processes in which Staufen participates in the cell suggests that this protein associates with many diverse RNA targets, some of which have been identified experimentally. Staufen binding mediates the recruitment of effectors via protein-protein and protein-RNA interactions. The structural determinants of a number of these interactions, as well as the structure of full-length Staufen, remain unknown. Here, we present the first solution structure models for full-length human Staufen155, showing that its domains are arranged as beads-on-a-string in the absence of RNA

Our experience in stereoelectroencephalography and electrical stimulation in a public hospital
Purpose : Stereo- electroencephalography (SEEG) is a procedure performed for patients with intractable epilepsy in order to anatomically define the epileptogenic zone (EZ) and the possible related functional cortical areas. Electrical stimulation (ES) was developed to identify with precision cortical structures essential to language and motor function, and to trigger seizures. The aim of this study is to analyze electrical stimulation (ES) findings in our patient population. Method : We analyzed 30 patients with drug resistant epilepsy from our Video- EEG Unit, who underwent a SEEG as part of a surgical plan. Cognitive tasks performed during ES were: hand tapping, naming, automatic speech (counting), reading and verbal fluency. Results : From the 30 patients, we trigger theirs usual seizures in 25 (83.33%), 159 seizures: 25 (15.5%) were trigger with hippocampus stimulation, 15 (9.4%) amygdala, 30 (18.8%) other temporal areas, 50 (31.4%) frontal areas, 15 (9.4%) parieto- occipital areas, and 24 seizures (15%) were obtained with the stimulation of two continues areas. In 14 (46.6%) patients we stimulate eloquent brain regions: 8 (57%) language, 7 (50%) patients were evaluated the motor area, 2 (14.2%)sensitive areas, 4 (28.4%) visual and 5 (28.4%)auditory sensations. We define EZ in all of the patients, 8 (26.6%) mesial temporal lobe epilepsy, 2 (6.6%) other temporal areas, 13 (43.3%) frontal lobe epilepsy, 5 (21.7%) parieto- occipital epilepsy, 2 (6.6%) insular epilepsy. Conclusion : ES is a procedure that allowed us the accurate location of the EZ, the temporal space dynamics of the epiletogenic network and the functional mapping, to plan cortical resection without overlap and to improve postsurgical prognosis.Fil: Giagante, Brenda.

Quality of Life in Partners of Young and Old Breast Cancer Survivors
Background: Partners of breast cancer survivors experience the effects of a spouse's cancer years after treatment. Partners of younger survivors (YP) may experience greater problems than partners of older survivors (OP), just as younger survivors experience greater problems than their older counterparts. Objectives: To 1) compare quality of life (QoL) in YP and OP, and 2) determine contributing factors to each group's QoL. Methods: Cross-sectional data were collected from YP (n=227) and OP (n=281) through self-report. MANOVA was used to determine differences between YP and OP on QoL while controlling for covariates. Multiple regression analyses were conducted to determine what contributes to each group's QoL. Results: YP reported better physical function (effect size (ES)= -0.57), lower marital satisfaction (ES=0.39), and lower overall QoL (ES=0.43) than partners of older survivors. Predictors of QoL also differed between partner groups. For YP, overall QoL was predicted by greater physical functioning, fewer depressive symptoms, higher marital satisfaction, higher parenting satisfaction, and more personal resources. R2= .47; F(5, 195)= 35.05; p<.001. For OP, overall QoL was predicted by fewer depressive symptoms, higher parenting satisfaction, higher spirituality, and greater social support from the breast cancer survivor spouse. R2= .33; F(4, 244)= 29.80; p<.001. Conclusions: OP reported greater QoL than YP. Common factors contributing to QoL between YP and OP were fewer depressive symptoms and higher parenting satisfaction. Implications for Practice: Partners of breast cancer survivors may need support coping with their spouseâs/partnerâs cancer. Partners of younger survivors may require more support than partners of older survivors.This study was coordinated by the ECOG-ACRIN Cancer Research Group (Robert L. Comis, MD and Mitchell D.
