Relación entre ansiedad, desempeño y riesgo de deserción en aspirantes a bachillerato

The purpose of this research was to explore the relationship between the academic qualifications of students with their tendency to experience emotional anxiety behaviors towards the school setting by means of a transversal descriptive study. Additionally, the association of these two variables with the likelihood of school failure was investigated. 385 junior high school students participated aspiring to enter a public senior high school. Academic performance was assessed based from the average grades at junior high school as well as from an admission exam. The probability of dropout was assessed by a self-reported questionnaire (Hernandez-Pozo, 2005). Additionally a computerized task was used based on the emotional version of the Stroop paradigm to measure the tendency for school anxiety (Hernandez-Pozo, Macias-Martinez, & Torres-Chavez, 2004). Results showed that students with the highest marks in the admission test, with better high school average or lower risk of dropout differed from their counterparts in terms of indices of the Stroop interference test. It is concluded that the emotional Stroop test is an instrument that reflects orderly risk to dropout and academic profile of applicants to senior high school.
Identification of a population of sleep-active cerebral cortex neurons

The presence of large-amplitude, slow waves in the EEG is a primary characteristic that distinguishes cerebral activity during sleep from that which occurs during wakefulness. Although sleep-active neurons have been identified in other brain areas, neurons that are specifically activated during slow-wave sleep have not previously been described in the cerebral cortex. We have identified a population of cells in the cortex that is activated during sleep in three mammalian species. These cortical neurons are a subset of GABAergic interneurons that express neuronal NOS (nNOS). Because Fos expression in these sleep-active, nNOS-immunoreactive (nNOS-ir) neurons parallels changes in the intensity of slow-wave activity in the EEG, and these neurons are innvervated by neurotransmitter systems previously implicated in sleep/wake control, cortical nNOS-ir neurons may be part of the neurobiological substrate that underlies homeostatic sleep regulation.

Functional analysis of the enteropathogenic Escherichia coli type III secretion system chaperone CesT identifies domains that mediate substrate interactions

In many Gram‐negative bacteria, a key indicator of pathogenic potential is the possession of a specialized type III secretion system, which is utilized to deliver virulence effector proteins directly into the host cell cytosol. Many of the proteins secreted from such systems require small cytosolic chaperones to maintain the secreted substrates in a secretion‐competent state. One such protein, CesT, serves a chaperone function for the enteropathogenic Escherichia coli (EPEC) translocated intimin receptor (Tir) protein, which confers upon EPEC the ability to alter host cell morphology following intimate bacterial attachment. Using a combination of complementary biochemical approaches, functional domains of CesT that mediate intermolecular interactions, involved in both chaperone–chaperone and chaperone–substrate associations, were determined. The CesT N‐terminal is implicated in chaperone dimerization, whereas the amphipathic α‐helical region of the C‐terminal, is intimately involved in substrate binding. By functional complementation of chaperone domains using the Salmonella SicA chaperone to generate chaperone chimeras, we show that CesT–Tir interaction proceeds by a mechanism potentially common to other type III secretion system chaperones.
Experiences of commodified nature: Performances and narratives of nature-based tourists on Stewart Island, New Zealand

This article explores the performances and narratives of nature-based tourists, more specifically of trampers, on Stewart Island, a remote tourism destination located in the southern waters of Aotearoa/New Zealand. It does so by reflecting on the concepts of commodification and of spectacle and how these may influence the experiences of tourists on the wild landscapes of Stewart Island. The study used an interpretive and embedded methodology, where the author was able to engage with the experiences of Others while tramping for extended periods of time on the island. This article concludes that the trampers’ experience of nature on Stewart Island is modulated by a media-constructed and media-sold tourism concept that fits well in a cultural and physical landscape that is able to provide an experience associated with a produced ‘nature’. Nature is therefore constructed to allow for an experience that is designed prior to the actual performance.
Estimating the burden of disease attributable to physical inactivity in South Africa in 2000.

OBJECTIVES To quantify the burden of disease attributable to physical inactivity in persons 15 years or older, by age group and sex, in South Africa for 2000. DESIGN The global comparative risk assessment (CRA) methodology of the World Health Organization was followed to estimate the disease burden attributable to physical inactivity. Levels of physical activity for South Africa were obtained from the World Health Survey 2003. A theoretical minimum risk exposure of zero, associated outcomes, relative risks, and revised burden of disease estimates were used to calculate population-attributable fractions and the burden attributed to physical inactivity. Monte Carlo simulation-modelling techniques were used for the uncertainty analysis. SETTING South Africa. SUBJECTS Adults >or= 15 years. OUTCOME MEASURES Deaths and disability-adjusted life years (DALYs) from ischaemic heart disease, ischaemic stroke, breast cancer, colon cancer, and type 2 diabetes mellitus. RESULTS Overall in adults >or= 15 years in 2000, 30% of ischaemic heart disease, 27% of colon cancer, 22% of ischaemic stroke, 20% of type 2 diabetes, and 17% of breast cancer were attributable to physical inactivity. Physical inactivity was estimated to have caused 17,037 (95% uncertainty interval 11,394 - 20,407), or 3.3% (95% uncertainty interval 2.2 - 3.9%) of all deaths in 2000, and 176,252 (95% uncertainty interval 133,733 - 203,628) DALYs, or 1.1% (95% uncertainty interval 0.8 - 1.3%) of all DALYs in 2000. CONCLUSIONS Compared with other regions and the global average, South African adults have a particularly high prevalence of physical inactivity. In terms of attributable deaths, physical inactivity ranked 9th compared with other risk factors, and 12th in terms of DALYs. There is a clear need to assess why South Africans are particularly inactive, and to ensure that physical activity/inactivity is addressed as a national health priority.
Theory? Or tools for social selection?

of the original article: Noam Chomsky and other linguists and psychologists have suggested that human linguistic behavior is somehow governed by a mental representation of a transformational grammar. Challenges to this controversial claim have often been met by invoking an explicitly computational perspective: It makes perfect sense to suppose that a grammar could be represented in the memory of a computational device and that this grammar could govern the device's use of a language. This paper urges, however, that the claim that humans are such a device is unsupported and that it seems unlikely that linguists and psychologists really want to claim any such thing. Evidence for the linguists' original claim is drawn from three main sources: the explanation of language comprehension and other linguistic abilities; evidence for formal properties of the rules of the grammar; and the explanation of language acquisition. It is argued in this paper that none of these sources provides support for the view that the grammar governs language processing in something like the way a program governs the operation of a programmed machine. The computational approach, on the contrary, suggests ways in which linguistic abilities can be explained without the attribution of any explicit representation of rules governing linguistic behavior.

Vaccination against Lyme disease: past, present, and future

Lyme borreliosis is a zoonotic disease caused by Borrelia burgdorferi sensu lato bacteria transmitted to humans and domestic animals by the bite of an Ixodes spp. tick (deer tick). Despite improvements in diagnostic tests and public awareness of Lyme disease, the reported cases have increased over the past decade to approximately 30,000 per year. Limitations and failed public acceptance of a human vaccine, comprised of the outer surface A (OspA) lipoprotein of B. burgdorferi, led to its demise, yet current research has opened doors to new strategies for protection against Lyme disease. In this review we discuss the enzootic cycle of B. burgdorferi, and the unique opportunities it poses to block infection or transmission at different levels. We present the correlates of protection for this infectious disease, the pros and cons of past vaccination strategies, and new paradigms for future vaccine design that would include elements of both the vector and the pathogen.
Modeling and forecasting short-term electricity load based on multi adaptive neural-fuzzy inference system by using temperature

In this paper, the use of Adaptive Neural-Fuzzy Inference System (ANFIS) to study the design of Short-Term Load Forecasting (STLF) systems for the east of Iran was explored. While reviewing the probability of chaos and predictability of electricity load curve by Lyapunov exponent, this paper forecasts consumed load by using multi ANFIS. Entries of the presented model are into the multi ANFIS including the date of the day, temperature maximum and minimum, climate condition and the previous days consumed load and its exit is forecasting of power load consumption of every season. The results show that temperature has an important role in load forecast.
Molecular Phylogeny of OVOL Genes Illustrates a Conserved C2H2 Zinc Finger Domain Coupled by Hypervariable Unstructured Regions

OVO-like proteins (OVOL) are members of the zinc finger protein family and serve as transcription factors to regulate gene expression in various differentiation processes. Recent studies have shown that OVOL genes are involved in epithelial development and differentiation in a wide variety of organisms; yet there is a lack of comprehensive studies that describe OVOL proteins from an evolutionary perspective. Using comparative genomic analysis, we traced three different OVOL genes (OVOL1-3) in vertebrates. One gene, OVOL3, was duplicated during a whole-genome-duplication event in fish, but only the copy (OVOL3b) was retained. From early-branching metazoa to humans, we found that a core domain, comprising a tetrad of C2H2 zinc fingers, is conserved. By domain comparison of the OVOL proteins, we found that they evolved in different metazoan lineages by attaching intrinsically-disordered (ID) segments of N/C-terminal extensions of 100 to 1000 amino acids to this conserved core. These ID regions originated independently across different animal lineages giving rise to different types of OVOL genes over the course of metazoan evolution. We illustrated the molecular evolution of metazoan OVOL genes over a period of 700 million years (MY). This study both extends our current understanding of the structure/function relationship of metazoan OVOL genes, and assembles a good platform for further characterization of OVOL genes from diverged organisms.
Facet Importance and Job Satisfaction: Another Look at the Range-of-Affect Hypothesis

The range-of-affect hypothesis (Locke, 1976) argues that facet importance is a key determinant of the level of satisfaction associated with any particular job facet. A larger range of facet satisfaction is expected for workers placing greater personal importance on a job facet (i.e., greater satisfaction with favorable conditions and greater dissatisfaction with unfavorable conditions). Although this hypothesis has been supported by studies using American samples, research is needed to assess its generalizability in other countries. This study takes a first step in that direction by finding support for the hypothesis in a sample of South African employees. In addition, unlike previous research, our study uses two alternative methods to examine the range-of-affect hypothesis. Practical implications and research directions are discussed.
A Hybrid Approach to Word Segmentation and POS Tagging

In this paper, we present a hybrid method for word segmentation and POS tagging. The target languages are those in which word boundaries are ambiguous, such as Chinese and Japanese. In the method, word-based and character-based processing is combined, and word segmentation and POS tagging are conducted simultaneously. Experimental results on multiple corpora show that the integrated method has high accuracy.
GVis: A Scalable Visualization Framework for Genomic Data

This paper describes a framework we have developed for the visual analysis of large-scale phylogeny hierarchies populated with the genomic data of various organisms. This framework allows the user to quickly browse the phylogeny hierarchy of organisms from the highest level down to the level of an individual genome for the desired organism of interest. Based on this framework, the user can initiate gene-finding and gene-matching analyses and view the resulting annotated coding potential graphs in the same multi-scale visualization framework, permitting correlative analysis and further investigation. This paper introduces our framework and describes the data structures and algorithms that support it.
Consequences of DNA-Dependent Protein Kinase Catalytic Subunit Deficiency on Recombinant Adeno-Associated Virus Genome Circularization and Heterodimerization in Muscle Tissue

ABSTRACT Circular concatemerization of the recombinant adeno-associated virus (rAAV) genome has been suggested as the predominant process facilitating long-term rAAV transduction in muscle. A recent study (S. Song, P. J. Laipis, K. I. Berns, and T. R. Flotte, Proc. Natl. Acad. Sci. USA 98:4084-4088, 2001) with SCID mice, which are defective in the DNA-dependent protein kinase catalytic subunit (DNA-PKcs), has suggested that DNA-PKcs regulates the removal of free rAAV vector ends in muscle tissue. In the present study, we have sought to evaluate whether a lack of DNA-PKcs activity reduces circularization of rAAV genomes in SCID muscle and whether such a reduction alters the directivity of heterodimerization. Consistent with the previous report, linear rAAV genomes and free vector ends were detected only in DNA-PKcs-deficient muscle by Southern blotting. Appreciable amounts of circular rAAV genomes were detected in both DNA-PKcs-deficient and wild-type muscle samples by Southern blotting and bacterial trapping experiments. The existence of double-D inverted terminal repeat circular intermediates in SCID and wild-type muscles was also supported by their sensitivity to T7 endonuclease I digestion. However, DNA-PKcs-deficient muscle did demonstrate a ∼50% reduction in the abundance of rescued circular genomes, despite equivalent levels of single rAAV transduction seen in wild-type animals. Dual trans-splicing lacZ vectors were used to functionally evaluate directional head-to-tail intermolecular viral genome concatamerization in vivo. Although AAV genomes are processed differently in SCID and wild-type muscles, a comparable level of trans-splicing-mediated β-galactosidase expression was observed in both strains, suggesting that both circular and linear AAV concatemers may have contributed to the trans-splicing-mediated transgene expression. In summary, we have shown that SCID skeletal muscle retains a fairly high capacity to form circular genomes, despite a significant increase in linear vector genomes. Furthermore, the alteration in equilibrium between circular and linear concatemer genomes caused by the lack of DNA-PKcs activity does not appear to significantly affect the efficiency of dual-vector gene expression from head-to-tail linear and/or circular heterodimers.

ASSESS: A Simulator of Soft Errors in the Configuration Memory of SRAM-Based FPGAs

In this paper a simulator of soft errors (SEUs) in the configuration memory of SRAM-based FPGAs is presented. The simulator, named ASSESS, adopts fault models for SEUs affecting the configuration bits controlling both logic and routing resources that have been demonstrated to be much more accurate than classical fault models adopted by academic and industrial fault simulators currently available. The simulator permits the propagation of faulty values to be traced in the circuit, thus allowing the analysis of the faulty circuit not only by observing its output, but also by studying fault activation and error propagation. ASSESS has been applied to several designs, including the miniMIPS microprocessor, chosen as a realistic test case to evaluate the capabilities of the simulator. The ASSESS simulations have been validated comparing their results with a fault injection campaign on circuits from the ITC'99 benchmark, resulting in an average error of only 0.1%.
Cutting to Live: A Phenomenology of Self‐Harm

This exploratory study utilizes a phenomenological methodology as described by Moustakas (Phenomenological research methods, Sage Publications, 1994). Data were gathered via qualitative face-to-face interviews from a midsize southwestern community. Eleven participants, ten females and one male, were included in this study. Data suggested three categories that described the participants’ experiences of self-harm: Self-harm is Misunderstood, Self-Harm has a Role, and Advice to Professionals. Among these categories, 11 themes emerged, including Self-Harm is Not Suicide, Self-Harm is an Addiction, Individuals Who Self-Harm are Traumatized, Help That’s Not Helpful, Self-Harm is a Release, Physical Pain versus Emotional Pain, Self-Harm IS Control, and Need to be Punished. Advice to professionals who work with individuals who self-harm is offered by the participants. The study concludes with a discussion of the phenomenon of self-harm, as well as clinical and training implications for professionals. Future directions for research are also discussed.
Code-switching, swearing and slang: The colloquial register of Basque in Greater Bilbao

This paper discusses the relationship of swearing and slang to code-switching based on data obtained in a Basque–Spanish language contact situation. The study is based on 22 hours of recorded material of 22 Basque bilinguals, both L1 and L2 Basque speakers. In Greater Bilbao, even the bilinguals who do not frequently code-switch shift to Spanish to introduce slang or swear words to otherwise Basque discourse. The susceptibility of these elements to switching is examined from structural, discursive and sociolinguistic points of view. The phenomena are understood to strengthen one another: when different stylistic and stance-taking devices co-occur, they become even more salient, thus underlining the effect for which they were introduced to the conversation.
Perceived Freedom, Aggression, and Responsibility, and the Assignment of Punishment

Summary The present experiment investigated the effects of the decision freedom of a transgressor on attributions of aggression and responsibility, and the assignment of punishment by naive observers. In a mass testing session Ss (N = 48 female college students) read one of four descriptions of Mr. X, a corporate vice president, who embezzled $50,000 under varying degrees of coercion. The degree of constraint operating on Mr. X prior to his decision to embezzle was manipulated by providing (or not providing) justifications for his behavior involving threats made upon the safety of Mr. X or his family. After reading a scenario Ss were asked to rate the aggressiveness of Mr. X on a semantic differential instrument and to indicate whether they perceived him as deserving of legal responsibility or punishment. Results revealed that constraints which reduced the transgressor's decision freedom also lessened the dispositional aggressiveness attributed, the blame assigned, and the retribution meted out to him.

Networks and social capital in the UK television industry: The weakness of weak ties

Accounts of the shift to post-industrial modes of employment have tended to present an over-simplified view of networks as an assemblage of contacts used to gain individual advantage in the labour market. Creative industries represent a challenge to this as typically they rely on networks to foster collaboration, trust and co-operation. In this article we explore how a variety of networks are used to promote both individual competition and co-operation in an industry where re-regulation has resulted in the break up of bureaucratic organizations and widespread casualization of the labour market. We argue that there is a need to extend the debate on the role of networks in a casualized labour market to examine how individuals organize themselves via the plethora of networks that result from organizational break up.We use qualitative data from a series of interviews with freelance television production workers in the United Kingdom to suggest that workers use networks as a source of competitive advantage and, at the same time, support and co-operation. Overall our research suggests that network activity is more complex, and networks themselves more dynamic, than existing research and theory implies.
