A TRANSIÇÃO ESTRUTURAL DA INDÚSTRIA BRASILEIRA: DA DIVERSIFICAÇÃO PARA A ESPECIALIZAÇÃO

The structural transition of the Brazilian industry: from diversification to specialization. Based on findings of Imbs and Wacziarg (2003), whose empirical study established the existence of a U-shaped pattern of the evolution of sectoral concentration in relation to the level of per capita income (countries first diversify, then start specializing again), this paper aims at determining more precisely the path of structural change that has being followed by the Brazilian industry in the last decades and at comparing it to the pattern found by the authors (and to the path followed by other countries in particular). For a better determination of this path, the empirical work started by an analysis of the evolution of the sectoral composition of the Brazilian industry, which brought to the conclusion that the productive structure in Brazil is changing very slowly, but that it has already started a specialization in low-tech sectors. Finally, after verifying that the diversification stage of the brazilian industrial structure has ended earlier (in terms of per capita income) that in all the other countries studied here, the analysis of the empirical results tried to explain why the specialization process is being so premature, and how prejudicial it has been to the economic development of the country. Key-words: structural change, diversification, specialization, economic development.

Rules of Origin as Trade or Foreign Policy Instruments? The European Union Policy on Products Manufactured in the Settlements in the West Bank and the Gaza Strip

This Article aims to shed some light on linkage between rules of origin and territorial disputes, and to analyze the alternative approaches available to policy makers in such cases. The choice between these alternatives is closely related to the broader subject of the interrelationships between international trade law and politics, which this Article will also address. It should be emphasized at the outset, that this Article does not aim to address the substantive territorial disputes regarding the West Bank and the Gaza Strip (nor the legality of the settlements located therein), Western Sahara, Taiwan, Northern Cyprus, or other disputed territories. The aim here is, rather, to explore the link between the particular position undertaken by a State (or an economic bloc) regarding the status of the disputed territory and the rules of origin applied to products manufactured in that territory.

Adaptation and Use of Subjectivity Lexicons for Domain Dependent Sentiment Classification

Sentiment analysis refers to the automatic extraction of sentiments from a natural language text. We study the effect of subjectivity-based features on sentiment classification on two lexicons and also propose new subjectivity-based features for sentiment classification. The subjectivity-based features we experiment with are based on the average word polarity and the new features that we propose are based on the occurrence of subjective words in review texts. Experimental results on hotel and movie reviews show an overall accuracy of about 84% and 71% in hotel and movie review domains respectively, improving the baseline using just the average word polarities by about 2% points.
Comparison of Vegetation Sampling Procedures in a Disturbed Mixed-Grass Prairie

Researchers currently use many different vegetation sampling methods in grassland systems (Shmida 1984, Stohlgren and Bull 1998, Barbour et al 1999). Each method examines the landscape at a slightly different grain (unit of observation) and extent (total area under study). Variation of study resolution (grain and extent together) and sampling frequency influences estimates of species richness and requires careful consideration to achieve an optimum sampling strategy (Turner 1989, Wiens 1989, Pickett and Cadenasso 1995, Whittaker et al 2001). The objective of sampling a plant community is generally to gain an accurate representation of the entire community; however, methods must balance increases in accuracy at a desired resolution with the available sampling resources to develop a feasible and efficient sampling strategy. At Fort Sill, Oklahoma, we tested the point-intercept, contiguous quadrat, and modified Whittaker sampling procedures to determine the optimum vegetation samA fundamental principle of landscape ecology is that overall resolution of a study can be changed by varying the grain and extent of sampling. However, sampling methods yielding a desirable resolution may not be the most efficient in terms of data gathered per unit of effort. We tested three methods simultaneously to select the optimum sampling method and resolution for a vegetation survey at Fort Sill, Oklahoma. The military’s standard sampling method, the Land Condition Trend Analysis Program, uses a modified pointintercept method to inventory vegetation. The point-intercept method may not adequately assess effects of disturbance on species richness in grasslands, so we tested it against contiguous quadrats and modified Whittaker plots. The point-intercept method, low resolution, was completed in the shortest time; however, it produced the least species richness. Contiguous quadrats, high resolution, required the greatest time investment, but had the highest species richness. Species richness in modified Whittaker plots (four levels of resolution) produced data quality similar to contiguous quadrats, but in less time. Modified Whittaker plots were most efficient because they detected the greatest number of species per unit of sampling effort and provided data at different spatial scales. © 2003 Oklahoma Academy of Science Comparison of Vegetation Sampling Procedures in a Disturbed Mixed-Grass Prairie
Pre-scheduled and adaptive parameter variation in MAX-MIN Ant System

MAX-MIN Ant System (MMAS) is an ant colony optimization (ACO) algorithm that was originally designed to start with a very explorative search phase and then to make a slow transition to an intensive exploitation of the best solutions found during the search. This design leads to a rather slow initial convergence of the algorithm, and, hence, to poor results if the algorithm does not run for sufficient time. This article illustrates that varying the parameter settings of MMAS while solving an instance may significantly improve the anytime search behavior of MMAS. Even rather simple pre-scheduled variations of the parameter settings that only depend on the number of iterations or the computation time show improvement over fixed parameter settings. The degree of improvement, however, is not uniform across problems. In particular, the improvement is very strong in the traveling salesman problem (TSP) but small, if at all noticeable, in the quadratic assignment problem (QAP). This paper also presents an adaptive parameter variation specifically designed for the TSP. The experimental results show that the pre-scheduled variations are comparable to the proposed adaptive variation in terms of the anytime behavior of MMAS.
Enhancing Nurse Engagement: The Role of Social Support and Job Characteristics

Nursing work engagement has become an increasingly crucial factor and a condition for high-quality health care performance, thus influencing the success of the organization. As the nursing profession is regarded as an emotionally demanding work environment, nurses as boundary-spanners of health care institutions need to have adequate job resources. This study examined the relationship between job resources consisting of social support, job feedback, task significance and work engagement. The sample comprised of 345 staff nurses working in three public hospitals in Peninsular Malaysia. Statistical results using hierarchical linear regression analysis shown that supervisor support, job feedback, and task significance were positively related to work engagement. In contrast, co-worker support has no significant relationship with work engagement.
Adoption Correlates and Share Effects of Electronic Data Interchange Systems in Marketing Channels

The establishment of electronic information interchange linkages between channel members offers significant potential for the transformation of their relationship, with significant benefits for all participants. The authors examine the adoption of a particular form of electronic data interchange (EDI), the computer-based interface offerings by insurance carriers to their independent agent communities. The study addresses adoption considerations and postadoption effects. Implications for system design are discussed.
Functional Characterization of the Semisynthetic Bile Acid Derivative INT-767, a Dual Farnesoid X Receptor and TGR5 Agonist

Two dedicated receptors for bile acids (BAs) have been identified, the nuclear hormone receptor farnesoid X receptor (FXR) and the G protein-coupled receptor TGR5, which represent attractive targets for the treatment of metabolic and chronic liver diseases. Previous work characterized 6α-ethyl-3α,7α-dihydroxy-5β-cholan-24-oic acid (INT-747), a potent and selective FXR agonist, as well as 6α-ethyl-23(S)-methyl-3α,7α,12α-trihydroxy-5β-cholan-24-oic acid (INT-777), a potent and selective TGR5 agonist. Here we characterize 6α-ethyl-3α,7α,23-trihydroxy-24-nor-5β-cholan-23-sulfate sodium salt (INT-767), a novel semisynthetic 23-sulfate derivative of INT-747. INT-767 is a potent agonist for both FXR (mean EC50, 30 nM by PerkinElmer AlphaScreen assay) and TGR5 (mean EC50, 630 nM by time resolved-fluorescence resonance energy transfer), the first compound described so far to potently and selectively activate both BA receptors. INT-767 does not show cytotoxic effects in HepG2 cells, does not inhibit cytochrome P450 enzymes, is highly stable to phase I and II enzymatic modifications, and does not inhibit the human ether-a-go-go-related gene potassium channel. In line with its dual activity, INT-767 induces FXR-dependent lipid uptake by adipocytes, with the beneficial effect of shuttling lipids from central hepatic to peripheral fat storage, and promotes TGR5-dependent glucagon-like peptide-1 secretion by enteroendocrine cells, a validated target in the treatment of type 2 diabetes. Moreover, INT-767 treatment markedly decreases cholesterol and triglyceride levels in diabetic db/db mice and in mice rendered diabetic by streptozotocin administration. Collectively, these preclinical results indicate that INT-767 is a safe and effective modulator of FXR and TGR5-dependent pathways, suggesting potential clinical applications in the treatment of liver and metabolic diseases.
Environmental Policy when People's Preferences are Inconsistent, Non-Welfaristic, or simply Not Developed

This paper discusses how a benevolent policy maker should act based on some, possibly non-welfaristic,ethical principle in cases where people's preferences are not perfectly informed,consistent and fully developed with regard to all goods, including all kinds of environmental goods, as is normally assumed in mainstream economic theory. When stated or revealed preferences do not reflect the maximization of individual welfare, it is argued that welfare,rather than preferences, has intrinsic value. However, it is also argued that properly designed stated preference methods may provide useful information about people’s views about alternative ethical ends, besides human well-being, and that policy makers should take such views seriously.
ENGINEERING AB INITIO DYNAMIC INTEROPERABILITY AND COMPOSABILITY VIA AGENT-MEDIATED INTROSPECTIVE SIMULATION

Complex software intensive simulation systems must respond to changing technology, environments, and requirements. Hence, dynamic extensibility and adaptability is a significant concern in an application domain. However, existing interoperability and composability solutions are limited in dealing with (1) dynamically evolving content needs of existing simulations and (2) run-time inclusion of new components into a simulation system. Simulations that are dynamically extensible, while being interoperable require principled designs that facilitate engineering extensibility, interoperability, and composability in the first place. We propose and examine the utility of a strategy based on an agent-mediated meta-simulation architecture.
Association between Extent of Simulated Degeneration of C5–C6 Disc and Biomechanical Parameters of a Model of the Full Cervical Spine: A Finite Element Analysis Study

Purpose To delineate the association between extent of degeneration of the disc at C5–C6, simulated in a model of the full cervical spine, and biomechanical responses of the model. Methods A validated three-dimensional model of an intact, healthy, adult full cervical spine (C1–C7) was constructed. This model was then modified to create three models simulating mild, moderate, and severe grades of degeneration of the disc at C5–C6. For each of these four models, we used the finite element analysis method to obtain three biomechanical parameters at various tissues in the model, under seven different physiologically relevant loadings. Results For each of the biomechanical parameters, the results were expressed as relative change in its value when a specified combination of simulated degeneration model and applied loading was used, with respect to the corresponding value in the intact model. We introduced a new measure, which we designate the composite biomechanical performance index (CBPI), whose value incorporates all of the aforementioned relative changes. Conclusions We found that CBPI increased with increase in the severity of disc degeneration simulated. The clinical relevance of CBPI should be addressed in future work.
PhaseLift: Exact and Stable Signal Recovery from Magnitude Measurements via Convex Programming

Suppose we wish to recover a signal \input amssym $\font\abc=cmmib10\def\bi#1{\hbox{\abc#1}} {\bi x} \in {\Bbb C}^n$ from m intensity measurements of the form $\font\abc=cmmib10\def\bi#1{\hbox{\abc#1}} |\langle \bi x,\bi z_i \rangle|^2$, $i = 1, 2, \ldots, m$; that is, from data in which phase information is missing. We prove that if the vectors $\font\abc=cmmib10\def\bi#1{\hbox{\abc#1}}{\bi z}_i$ are sampled independently and uniformly at random on the unit sphere, then the signal x can be recovered exactly (up to a global phase factor) by solving a convenient semidefinite program–‐a trace‐norm minimization problem; this holds with large probability provided that m is on the order of $n {\log n}$, and without any assumption about the signal whatsoever. This novel result demonstrates that in some instances, the combinatorial phase retrieval problem can be solved by convex programming techniques. Finally, we also prove that our methodology is robust vis‐à‐vis additive noise. © 2012 Wiley Periodicals, Inc.
Morphological classification of the OSU Bright Spiral Galaxy Survey

To quantify the distribution of bar shapes in spiral galaxies, we have analysed 113 H-band and 89 B-band galaxy images from the Ohio State University Bright Spiral Galaxy Survey. Parameters measuring bar shape and position along the Hubble sequence were obtained in each waveband. Evidence was found for a bimodality in the distribution of bar shape, implying that barred and unbarred galaxies are not just the extrema of a single distribution, and that any evolution between these two states must occur on a rapid time-scale. Objective bar shapes measured in the H-band were found to be more closely related to visual classifications than B-band bar strengths, as the B-band images are somewhat compromised by localized star formation, especially in later type systems. Galaxies were found to be more centrally concentrated in the infrared. Later type galaxies showed greater asymmetry in the optical than the infrared, presumably again owing to localized star formation, but on average the bar shapes in the two bands were found to be the same.
Educating for Citizenship.

There has been a quiet revolution occurring in the academy over the last two decades. Civic concerns have achieved new visibility alongside the traditional academic mission of higher education. It is difficult to find a college campus that does not tout a coordinating center for community service, service-learning courses, or research centers devoted to distinctly civic issues. Institutions have redefined themselves to be more responsible citizens in their communities. Nearly a thousand college presidents are members of Campus Compact, an organization created to promote greater campuscommunity involvement. Seventy-eight percent of students participate in some sort of service experience before they graduate.
G-Chaplygin Systems With Internal Symmetries, Truncation, And An (Almost) Symplectic View Of Chaplygin"S Ball

Via compression ((18, 8)) we write the n-dimensional Chaplygin sphere system as an almost Hamiltonian system on TSO(n) with internal symmetry group SO(n 1). We show how this symmetry group can be factored out, and pass to the fully reduced system on (a fiber bundle over) TSn 1. This approach yields an explicit description of the reduced system in terms of the geometric data involved. Due to this description we can study Hamiltoniz- ability of the system. It turns out that the homogeneous Chaplygin ball, which is not Hamiltonian at the TSO(n)-level, is Hamiltonian at the TS n 1 -level. Moreover, the 3-dimensional ball becomes Hamiltonian at the TS 2 -level after time reparametrization, whereby we re-prove a result of (4, 5) in symplecto- geometric terms. We also study compression followed by reduction of general- ized Chaplygin systems.
A Genome-Wide Investigation of Copy Number Variation in Patients with Sporadic Brain Arteriovenous Malformation

Background Brain arteriovenous malformations (BAVM) are clusters of abnormal blood vessels, with shunting of blood from the arterial to venous circulation and a high risk of rupture and intracranial hemorrhage. Most BAVMs are sporadic, but also occur in patients with Hereditary Hemorrhagic Telangiectasia, a Mendelian disorder caused by mutations in genes in the transforming growth factor beta (TGFβ) signaling pathway. Methods To investigate whether copy number variations (CNVs) contribute to risk of sporadic BAVM, we performed a genome-wide association study in 371 sporadic BAVM cases and 563 healthy controls, all Caucasian. Cases and controls were genotyped using the Affymetrix 6.0 array. CNVs were called using the PennCNV and Birdsuite algorithms and analyzed via segment-based and gene-based approaches. Common and rare CNVs were evaluated for association with BAVM. Results A CNV region on 1p36.13, containing the neuroblastoma breakpoint family, member 1 gene (NBPF1), was significantly enriched with duplications in BAVM cases compared to controls (P = 2.2×10−9); NBPF1 was also significantly associated with BAVM in gene-based analysis using both PennCNV and Birdsuite. We experimentally validated the 1p36.13 duplication; however, the association did not replicate in an independent cohort of 184 sporadic BAVM cases and 182 controls (OR = 0.81, P = 0.8). Rare CNV analysis did not identify genes significantly associated with BAVM. Conclusion We did not identify common CNVs associated with sporadic BAVM that replicated in an independent cohort. Replication in larger cohorts is required to elucidate the possible role of common or rare CNVs in BAVM pathogenesis.
Strains and Stressors: An Analysis of Touchscreen Learning in Genetically Diverse Mouse Strains

Touchscreen-based systems are growing in popularity as a tractable, translational approach for studying learning and cognition in rodents. However, while mouse strains are well known to differ in learning across various settings, performance variation between strains in touchscreen learning has not been well described. The selection of appropriate genetic strains and backgrounds is critical to the design of touchscreen-based studies and provides a basis for elucidating genetic factors moderating behavior. Here we provide a quantitative foundation for visual discrimination and reversal learning using touchscreen assays across a total of 35 genotypes. We found significant differences in operant performance and learning, including faster reversal learning in DBA/2J compared to C57BL/6J mice. We then assessed DBA/2J and C57BL/6J for differential sensitivity to an environmental insult by testing for alterations in reversal learning following exposure to repeated swim stress. Stress facilitated reversal learning (selectively during the late stage of reversal) in C57BL/6J, but did not affect learning in DBA/2J. To dissect genetic factors underlying these differences, we phenotyped a family of 27 BXD strains generated by crossing C57BL/6J and DBA/2J. There was marked variation in discrimination, reversal and extinction learning across the BXD strains, suggesting this task may be useful for identifying underlying genetic differences. Moreover, different measures of touchscreen learning were only modestly correlated in the BXD strains, indicating that these processes are comparatively independent at both genetic and phenotypic levels. Finally, we examined the behavioral structure of learning via principal component analysis of the current data, plus an archival dataset, totaling 765 mice. This revealed 5 independent factors suggestive of “reversal learning,” “motivation-related late reversal learning,” “discrimination learning,” “speed to respond,” and “motivation during discrimination. ” Together, these findings provide a valuable reference to inform the choice of strains and genetic backgrounds in future studies using touchscreen-based tasks.
