Estimating Ideology of Brazilian Legislative Parties, 1990–2005: A Research Communication

We present a new data set on the left-right placement of major Brazilian political parties serving in the first five legislatures under democracy. On the basis of survey responses of more than 850 federal legislators from 1990 to 2005, we generate party placements on an ideological scale where 1 = "left" and 10 = "right. " The data are rescaled to account for idiosyncrasies in responses as well as variation in use of the survey scale across time. We discuss both the validity and the reliability of our new measures by comparing them to other data sets. We further discuss three substantive issues that the data reveal. First, ideological polarization has moderated over time. Second, the median legislator has shifted noticeably to the left and now stands equidistant from the influential PT and PSDB, the parties that have anchored recent presidential elections. Third, Brazilian political elites continue to shun self-identifications associated with political conservatism or neoliberalism.
Refining the cognitive decathlon

We argue that cognitive tests of intelligent agents should use modern intelligence theory to help ensure the test battery covers key aspects of cognition and decomposes them as diagnostically as possible. To this end we assess the recent BICA cognitive decathlon proposal [15] on the Cattel-Horn-Carrol (CHC) factor model of human intelligence [11], and suggest tests to fill the gaps. Some of those tests come from cognitive performance software developed by NTI [17 & 18]. Appealing again to CHC theory, we note remaining gaps and suggest known tests which can fill them.
Regulatory T Cells Selectively Express Toll-like Receptors and Are Activated by Lipopolysaccharide

Regulatory CD4 T cells (Treg) control inflammatory reactions to commensal bacteria and opportunist pathogens. Activation of Treg functions during these processes might be mediated by host-derived proinflammatory molecules or directly by bacterial products. We tested the hypothesis that engagement of germline-encoded receptors expressed by Treg participate in the triggering of their function. We report that the subset of CD4 cells known to exert regulatory functions in vivo (CD45RBlow CD25+) selectively express Toll-like receptors (TLR)-4, -5, -7, and -8. Exposure of CD4+ CD25+ cells to the TLR-4 ligand lipopolysaccharide (LPS) induces up-regulation of several activation markers and enhances their survival/proliferation. This proliferative response does not require antigen-presenting cells and is augmented by T cell receptor triggering and interleukin 2 stimulation. Most importantly, LPS treatment increases CD4+ CD25+ cell suppressor efficiency by 10-fold and reveals suppressive activity in the CD4+ CD45RBlow CD25− subset that when tested ex-vivo, scores negative. Moreover, LPS-activated Treg efficiently control naive CD4 T cell–dependent wasting disease. These findings provide the first evidence that Treg respond directly to proinflammatory bacterial products, a mechanism that likely contributes to the control of inflammatory responses.
Climate forums: virtual discourses on climate change and the sustainable lifestyle

Internet discussion forums and other forms of virtual social networking media are increasingly being used as sites of discursive practice. Quite apart from the research opportunities offered by conventional forms of Internet research (such as surveys and polls), discussion forums (alongside Web-logs and social networking sites) arguably provide new opportunities for social researchers to gather data in this very particular, but nonetheless popular cultural context. This paper explores the phenomenon through the large amount of textual data generated from an article on climate change and sustainable lifestyles in the Guardian newspaper. The discourses that emerged in reaction to this article provide valuable insights into the social construction of climate change and sustainable lifestyles, demonstrating conflicting arguments relating to the acceptance of climate change as a human-induced phenomenon, the reliability of data used to assert arguments concerning global warming and the contested views expressed over the value of adopting more sustainable lifestyles. Further, the paper argues that environmental social scientists need to become aware of the potential for analysing virtual discussion forums and social networking sites as valuable data sources for their research, recognising that these represent both cultural artefacts in their own right and alternative sites of discursive practice for anonymous and immediate everyday talk.
Root-associated bacterial endophytes from Ralstonia solanacearum resistant and susceptible tomato cultivars and their pathogen antagonistic effects

This study was undertaken to assess if the root-associated native bacterial endophytes in tomato have any bearing in governing the host resistance to the wilt pathogen Ralstonia solanacearum. Internal colonization of roots by bacterial endophytes was confirmed through confocal imaging after SYTO-9 staining. Endophytes were isolated from surface-sterilized roots of 4-weeks-old seedlings of known wilt resistant (R) tomato cultivar Arka Abha and susceptible (S) cv. Arka Vikas on nutrient agar after plating the tissue homogenate. Arka Abha displayed more diversity with nine distinct organisms while Arka Vikas showed five species with two common organisms (Pseudomonas oleovorans and Agrobacterium tumefaciens). Screening for general indicators of biocontrol potential showed more isolates from Arka Abha positive for siderophore, HCN and antibiotic biosynthesis than from Arka Vikas. Direct challenge against the pathogen indicated strong antagonism by three Arka Abha isolates (P. oleovorans, Pantoea ananatis, and Enterobacter cloacae) and moderate activity by three others, while just one isolate from Arka Vikas (P. oleovorans) showed strong antagonism. Validation for the presence of bacterial endophytes on three R cultivars (Arka Alok, Arka Ananya, Arka Samrat) showed 8–9 antagonistic bacteria in them in comparison with four species in the three S cultivars (Arka Ashish, Arka Meghali, Arka Saurabhav). Altogether 34 isolates belonging to five classes, 16 genera and 27 species with 23 of them exhibiting pathogen antagonism were isolated from the four R cultivars against 17 isolates under three classes, seven genera and 13 species from the four S cultivars with eight isolates displaying antagonistic effects. The prevalence of higher endophytic bacterial diversity and more antagonistic organisms associated with the seedling roots of resistant cultivars over susceptible genotypes suggest a possible role by the root-associated endophytes in natural defense against the pathogen.
Grammar string : a novel ncRNA secondary structure representation

Multiple ncRNA alignment has important applications in homologous ncRNA consensus structure derivation, novel ncRNA identification, and known ncRNA classification. As many ncRNAs’ functions are determined by both their sequences and secondary structures, accurate ncRNA alignment algorithms must maximize both sequence and structural similarity simultaneously, incurring high computational cost. Faster secondary structure modeling and alignment methods using trees, graphs, probability matrices have thus been developed. Despite promising results from existing ncRNA alignment tools, there is a need for more efficient and accurate ncRNA secondary structure modeling and alignment methods. In this work, we introduce grammar string, a novel ncRNA secondary structure representation that encodes an ncRNA’s sequence and secondary structure in the parameter space of a context-free grammar (CFG). Being a string defined on a special alphabet constructed from a CFG, it converts ncRNA alignment into sequence alignment with O(n2) complexity. We align hundreds of ncRNA families from BraliBase 2.1 using grammar strings and compare their consensus structure with Murlet using the structures extracted from Rfam as reference. Our experiments have shown that grammar string based multiple sequence alignment competes favorably in consensus structure quality with Murlet. Source codes and experimental data are available at http://www.cse. msu.edu/~yannisun/grammar-string.
Modeling information repositories consistency and auditing through Alloy and CCalc

We present a case study on which a model checking language (Alloy) and a non-monotonic causal language (CCalc) are used for modeling the auditing process of an information repository through a MultiAgents System. Alloy and CCalc are used for identifying inconsistencies and simulating an automatic correction process carried out by intelligent agents supervised by human users. Similarities and strengths of both languages are pointed out.
Development of a biped walking robot having antagonistic driven joints using nonlinear spring mechanism

The authors are engaged in studies of biped walking robots from the following two viewpoints. One is a viewpoint as a human science. The other is a viewpoint towards the development of humanoid robots. In the current research concerning a biped walking robot, there is no developed example of a life-size biped walking robot with the antagonistically driven joints by which the human musculo-skeletal system is imitated in lower limbs. Humans are considered to exhibit walking behavior, both efficient and capable of flexibly coping with contact with the outside environment. However, developed biped walking robots can not realize the human walking. The human joint is driven by two or more antagonistic muscle groups. Humans can vary the joint stiffness, using nonlinear spring characteristics possessed by the muscle themselves. The function is an indispensable function for a humanoid. Therefore, the authors designed and built an anthropomorphic biped walking robot having antagonistic driven joints. In this paper, the authors introduce the design method of the robot. The authors performed walking experiments with the robot. As a result, quasi-dynamic biped walking using antagonist driven joint was realized. The walking speed was 7.68 s/step with a 0.1 m step length.
IoT Edge Network Design Through 3D Massive MIMO

In this paper, the connectivity of Internet of Things (IoT) network via 3D massive MIMO technology has been analysed. We have deployed a single-cell to create connectivity for a considerable IoT users. Comprehensive channel model has been driven in the elevation domain as well as in the azimuthal domain. Additionally, We have calculated bandwidth efficiency (BE) equations for zero-forcing (ZF), and the proposed scheme named as improved zero-forcing (IZF) in IoT network having connectivity through 3D massive MIMO. The proposed scheme has been tested through various important parameters such as single-to-noise (SNR) and changing the angular spread. Additionally, we have also checked the values of BE with different number of IoT users. The comprehensive analysis has been performed through multiple antenna configurations. The simulations indicate that, our proposed IZF outperforms traditional ZF in terms of BE while varying several parameters. Furthermore, we implicate that the 3D massive MIMO technology can be applied freely for connecting an IoT edge networks.
Variant of Gardener's Syndrome

TO THE EDITOR: Recently, I came across a 54-yr-old white woman with a history of abdominal pain and weight loss. Evaluation included EGD (Fig. 1), colonoscopy, and CT scan of the abdomen. She was found to have multiple benign gastric polyps. Her records revealed a past history of multiple intradermal and junctional nevus. Later, she developed obstructive jaundice, and ERCP detected pancreatic cancer. There are many well-known syndromes reported with an association between gastrointestinal polyps, ectodermal neoplasia and pancreatic cancer. Examples of such syndromes (1) are Peutz-Jegher syndrome (mucocutaneous pigmentation and intestinal polyposis) and Cronkhite-Cananda syndrome (ectodermal defects such as alopecia, excessive skin pigmentation, and generalized gastrointestinal popyposis) and Gardener’s syndrome (soft tissue tumors such as sebaceous cysts and fibromas, bony tumors such as osteoma, adenomatous polyps of the colon and rectum associated with development of periampullary tumors). The case reported here had a somewhat different configuration: pancreatic cancer, multiple benign gastric polyps, multiple intradermal and junctional nevus, and no colonic or rectal polyposis. The purpose of this letter is to find out whether any similar cases have been noticed by readers. Is this reported combination just a coincidence, or could here be any relationship that should be explored further?
Cognitive divergence and shared mental models in software development project teams

This study examined the development of shared mental models in software development teams over time. Contrary to predictions, team members' mental models about the group's work and each other's expertise did not become more similar over time. Structural equation modelling revealed that as role differentiation increased in these teams, it led to a decrease in interaction and a corresponding decline in shared mental models. Implications for research on shared cognition and team development are explored. Copyright © 2001 John Wiley & Sons, Ltd.
Timing of first sexual intercourse in a relationship: Expectations, experiences, and perceptions of others

We investigated 242 college students’ expectations about when sexual intercourse would first occur within different types of relationships. Participants reported their personal expectations, experiences, and beliefs about the sexual expectations of the “average woman” and “average man” in relationships with or without strong physical attraction and emotional involvement. Results show that, in general, men expect sexual intercourse after significantly fewer dates (approximately 9–11) than women do (approximately 15–18). In addition, expectations were related to actual experiences for women, but not men. Participants also tended to exhibit pluralistic ignorance about sex, believing in a norm for the average person of their gender that was considerably more permissive than were their own standards. The average man and woman were perceived as expecting sex earlier within a relationship and irrespective of physical attraction or emotional involvement. In contrast, most men and women only expected sex when they.
Sea urchin akt activity is Runx-dependent and required for post-cleavage stage cell division

Summary In animal development following the initial cleavage stage of embryogenesis, the cell cycle becomes dependent on intercellular signaling and controlled by the genomically encoded ontogenetic program. Runx transcription factors are critical regulators of metazoan developmental signaling, and we have shown that the sea urchin Runx gene runt-1, which is globally expressed during early embryogenesis, functions in support of blastula stage cell proliferation and expression of the mitogenic genes pkc1, cyclinD, and several wnts. To obtain a more comprehensive list of early runt-1 regulatory targets, we screened a Strongylocentrotus purpuratus microarray to identify genes mis-expressed in mid-blastula stage runt-1 morphants. This analysis showed that loss of Runx function perturbs the expression of multiple genes involved in cell division, including the pro-growth and survival kinase Akt (PKB), which is significantly underexpressed in runt-1 morphants. Further genomic analysis revealed that Akt is encoded by two genes in the S. purpuratus genome, akt-1 and akt-2, both of which contain numerous canonical Runx target sequences. The transcripts of both genes accumulate several fold during blastula stage, contingent on runt-1 expression. Inhibiting Akt expression or activity causes blastula stage cell cycle arrest, whereas overexpression of akt-1 mRNA rescues cell proliferation in runt-1 morphants. These results indicate that post-cleavage stage cell division requires Runx-dependent expression of akt.
Keratoprosthesis: preliminary results of an artificial corneal button as a full-thickness implant in the rabbit model.

PURPOSE To develop a prototype artificial cornea and evaluate it in the rabbit model. METHODS Hydrogel core-and-skirt keratoprostheses were made and were inserted as full-thickness implants covered with conjunctival flaps in the right eyes of eight rabbits. RESULTS Peroperative complications related to inadequate mechanical strength led to failure in the early postoperative period in three animals, one was euthanased for an unrelated reason and the remaining four have been successful for up to 16 weeks' follow-up. CONCLUSIONS Full-thickness implantation of an artificial cornea, analogous to penetrating keratoplasty, has been achieved in the rabbit model. Histological findings confirm that integration of the prosthesis with host tissue occurs. The main complications encountered in this preliminary series were related to inadequate strength of the sponge skirt of this prototype device. Work in our laboratories is now concentrated upon improving the mechanical qualities of the hydrogel skirt and on the enhancement of biointegration.
Association of the rs7395662 SNP in the MADD-FOLH1 and Several Environmental Factors with Serum Lipid Levels in the Mulao and Han Populations

Background: The rs7395662 single nucleotide polymorphism (SNP) in the MADD-FOLH1 has been associated with serum lipid traits, but the results are inconsistent in different populations. The present study was undertaken to investigate the association of rs7395662 SNP and several environmental factors with serum lipid levels in the Guangxi Mulao and Han populations. Method: A total of 721 subjects of Mulao and 727 subjects of Han Chinese were randomly selected from our previous stratified randomized samples. Genotyping of the SNP was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and confirmed by direct sequencing. Results: Serum apolipoprotein (Apo) B levels were higher in Mulao than in Han (P < 0.01). The allelic and genotypic frequencies in Han were different between males and females (P < 0.05 for each), but there was no difference between Mulao and Han or between Mulao males and females. The levels of low-density lipoprotein cholesterol (LDL-C) and ApoB in Mulao females were different among the genotypes (P < 0.05), the G allele carriers had higher LDL-C and ApoB levels than the G allele non-carriers. The levels of total cholesterol (TC), triglyceride (TG), LDL-C and ApoB in Han males and TC, TG and high-density lipoprotein cholesterol (HDL-C) in Han females were different among the genotypes (P < 0.05-0.01), the subjects with GG genotype in Han males had higher TC, TG, and ApoB and lower LDL-C levels than the subjects with AA or AG genotype, and the G allele carriers in Han females had lower TC and HDL-C levels than the G allele non-carriers. The levels of LDL-C and ApoB in Mulao females were correlated with the genotypes (P < 0.05 for each). The levels of HDL-C and ApoAI in Han males and HDL-C in Han females were correlated with genotypes (P < 0.05-0.001). Serum lipid parameters were also correlated with several environmental factors in both ethnic groups (P < 0.05-0.01). Conclusion: The association of rs7395662 SNP and serum lipid levels is different between the Mulao and Han populations, and between males and females in both ethnic groups.
Using Generalized Annotated Programs to Solve Social Network Diffusion Optimization Problems

There has been extensive work in many different fields on how phenomena of interest (e.g., diseases, innovation, product adoption) “diffuse” through a social network. As social networks increasingly become a fabric of society, there is a need to make “optimal” decisions with respect to an observed model of diffusion. For example, in epidemiology, officials want to find a set of k individuals in a social network which, if treated, would minimize spread of a disease. In marketing, campaign managers try to identify a set of k customers that, if given a free sample, would generate maximal “buzz” about the product. In this article, we first show that the well-known Generalized Annotated Program (GAP) paradigm can be used to express many existing diffusion models. We then define a class of problems called Social Network Diffusion Optimization Problems (SNDOPs). SNDOPs have four parts: (i) a diffusion model expressed as a GAP, (ii) an objective function we want to optimize with respect to a given diffusion model, (iii) an integer k > 0 describing resources (e.g., medication) that can be placed at nodes, (iv) a logical condition VC that governs which nodes can have a resource (e.g., only children above the age of 5 can be treated with a given medication). We study the computational complexity of SNDOPs and show both NP-completeness results as well as results on complexity of approximation. We then develop an exact and a heuristic algorithm to solve a large class of SNDOPproblems and show that our GREEDY-SNDOPs algorithm achieves the best possible approximation ratio that a polynomial algorithm can achieve (unless P = NP). We conclude with a prototype experimental implementation to solve SNDOPs that looks at a real-world Wikipedia dataset consisting of over 103,000 edges.
Estimating the Largest Eigenvalue of a Positive Definite Matrix

The power method for computing the dominant eigenvector of a positive definite matrix will converge slowly when the dominant eigenvalue is poorly separated from the next largest eigenvalue. In this note it is shown that in spite of this slow convergence, the Rayleigh quotient will often give a good approximation to the domi- nant eigenvalue after a very few iterations-even when the order of the matrix is large.
A Novel Demonstration of Enhanced Memory Associated with Emotional Arousal

The relationship between emotional arousal and long-term memory is addressed in two experiments in which subjects viewed either a relatively emotionally neutral short story (presented as a brief slide show) or a closely matched but more emotionally arousing story and were tested for retention of the story 2 weeks later. Experiment 1 provides an essential replication of the results of Heuer and Reisberg (1990) and illustrates the common interpretive problem posed by the use of different stimuli (slides) in the neutral versus emotional stories. In Experiment 2, identical slides (and sequence) were used in both the neutral and arousal stories. Two different stories were created by varying the narration that accompanied each slide. In both experiments, subjects who viewed the arousal story both experienced a greater emotional reaction to the story than did the subjects who viewed the neutral story, and subsequently exhibited enhanced memory for the story. Subjects in Experiment 2 who viewed the arousal story also recalled more slides than did the subjects who viewed the neutral story. This effect was greatest for story phase 2, the phase in which the emotional slide narration occurred. Because this enhanced retention of the story slides cannot be explained by any differences in the slides themselves, the results provide new evidence to support the contention that emotional arousal influences long-term memory in normal human subjects.
Creativity and Personality: Suggestions for a Theory

An attempt is made in this article to relate creativity to personality in a much more definitive way than has been done previously and to use the known correlates of personality to suggest a theory of creativity that would explain many of the phenomena associated with this concept. A causal chain is suggested reaching from DNA to creative achievement, based largely on experimental findings not usually considered in relation to creativity (e.g., latent inhibition). Inevitably, the model is highly speculative, but it is testable and hence may prove useful in not only accounting for many observations and experimental results but also in suggesting new experiments and observations.
