Predicting outcome after thrombolysis in acute myocardial infarction according to ST-segment resolution at 90 minutes: a substudy of the GUSTO-III trial. Global Use of Strategies To Open occluded coronary arteries.

BACKGROUND Resolution of ST-segment elevation after thrombolysis for acute myocardial infarction has been shown to have prognostic significance 3 hours (180 minutes) after the initiation of therapy. Whether prognostically useful information can be achieved as early as 90 minutes after thrombolysis is unknown. METHODS An electrocardiographic substudy of 2352 patients from the Global Use of Strategies To Open occluded coronary arteries (GUSTO-III) trial was undertaken to compare outcomes according to ST-segment resolution at 90 minutes versus 180 minutes after administration of thrombolytic therapy. RESULTS Of 2352 patients in the substudy, 2241 had a baseline and 90-minute electrocardiogram, and 2218 had a baseline and 180-minute ECG. Complete ST-segment resolution occurred in 44.2% of patients at 90 minutes and 56.5% of patients at 180 minutes. ST-segment resolution at both 90 and 180 minutes was associated with lower 30-day and 1-year mortality. Multivariate analysis revealed ST-segment resolution at 90 minutes to be an equally strong predictor of 30-day mortality as resolution at 180 minutes. Patients who were at particularly high risk for mortality were those aged >70 years, those who presented with Killip class >1, and those with anterior infarctions. CONCLUSIONS The presence of ST-segment resolution on standard 12-lead electrocardiographic monitoring 90 minutes after thrombolysis is a useful independent predictor of mortality at 30 days and 1 year. The potential for obtaining prognostic results as early as 90 minutes after thrombolysis sets a new precedent for optimum electrocardiographic monitoring times in these patients.
Strong spatial mixing for lattice graphs with fewer colours

Recursively-constructed couplings have been used in the past for mixing on trees. We show for the first time how to extend this technique to nontree-like graphs such as the integer lattice. Using this method, we obtain the following general result. Suppose that G is a triangle-free graph and that for some /spl Delta/ /spl ges/ 3, the maximum degree of G is at most /spl Delta/. We show that the spin system consisting of q-colourings of G has strong spatial mixing, provided q > /spl alpha//spl Delta/, where /spl alpha/ /spl ap/ 1.76322 is the solution to /spl alpha//sup /spl alpha// = e. Note that we have no additional lower bound on q or /spl Delta/. This is important for us because our main objective is to have results which are applicable to the lattices studied in statistical physics such as the integer lattice /spl Zopf//sup d/ and the triangular lattice. For these graphs (in fact, for any graph in which the distance-k neighbourhood of a vertex grows sub-exponentially in k), strong spatial mixing implies that there is a unique infinite-volume Gibbs measure. That is, there is one macroscopic equilibrium rather than many. We extend our general result, obtaining, for example, the first "hand proof" of strong spatial mixing for 7-colourings of triangle-free 4-regular graphs. (Computer-assisted proofs of this result were provided by Salas and Sokal (1997) for the rectangular lattice and by Bubley et al. (1999)). The extension also gives the first hand proof of strong spatial mixing for 5-colourings of triangle-free 3-regular graphs. (A computer-assisted proof for the special case of the hexagonal lattice was provided by Salas and Sokal). Towards the end of the paper we show how to improve our general technique by considering the geometry of the lattice. The idea is to construct the recursive coupling from a system of recurrences rather than from a single recurrence. We use the geometry of the lattice to derive the system of recurrences. This gives us an analysis with a horizon of more than one level of induction, which leads to improved results. We illustrate this idea by proving strong spatial mixing for q = 10 on the lattice /spl Zopf//sup 3/. Finally, we apply the idea to the triangular lattice, adding computational assistance. This gives us the first (machine-assisted) proof of strong spatial mixing for 10-colourings of the triangular lattice. (Such a proof for 11 colours was given by Salas and Sokal.).
Quantum Walk on the Line

Motivated by the immense success of random walk and Markov chain methods in the design of classical algorithms, we consider quantum walks on graphs. We analyse in detail the behaviour of unbiased quantum walk on the line, with the example of a typical walk, the “Hadamard walk”. We show that after t time steps, the probability distribution on the line induced by the Hadamard walk is almost uniformly distributed over the interval [ − t/ √ 2 , t/ √ 2]. This implies that the same walk deﬁned on the circle mixes in linear time. This is in direct contrast with the quadratic mixing time for the corresponding classical walk. We conclude by indicating how our techniques may be applied to more general graphs.
Knowledge in a “Shared and Interdependent World”: Implications for a Progressive Leadership of Cities and Regions

This paper suggests the need for a more penetrating research agenda around the theme of leadership for progressive urban and regional change. While a much improved understanding of the leadership contribution is emerging in the urban and regional studies context, no strong organizing discourse has yet surfaced in the debate around the leadership of cities and regions that might serve as a guide to the development of a more critical research and leadership development agenda going forward. This paper seeks to contribute to debate around theory and practice by exploring the idea that it is knowledge “writ large”—how it is created, developed, combined and deployed—that lies at the heart of a progressive transformation of cities and regions. And that consequently, we need to think of how leadership works in, for and through these settings alongside a broader understanding of the dynamics of knowledge. The paper draws on recent research and policy literature to present an argument for a re-framed leadership practice across European cities and regions and concludes with suggestions for a new combined and underpinning research agenda.
How perceived autonomy support from adults and peer motivational climate are related with self-determined motivation among young athletes

Assessing the motivational responses of 662 young athletes aged 11-16 years, this study examined a model of motivation that incorporates constructs from achievement goal and self-determination theories. The focus was on the prediction of young athletes’ self-determined motivation from perceived autonomy support from parent and coaches and from dimensions of peer motivational climate. The structural equation modelling analysis supported the model in which autonomy support from parents and coaches as antecedents in forming the perceived peer motivational climate are related to prediction of self-determined motivation. Autonomy support from parents was a stronger predictor of self-determined motivation than autonomy support from coaches. From the dimensions of peer motivational climate, the intra-team competition/ability was the only dimension that had a negative significant direct effect on self-determined motivation. From an applied perspective, these results highlighted the importance of peers as essential influencers, along with adults, on young athletes’ sport motivation.
Extraterritoriality of Human Rights Treaties

On the eve of the planned U.S. invasion of Haiti, responding to an appeal from the International Committee of the Red Cross to apply international humanitarian law, the United States stated that [i]f it becomes necessary to use force and engage in hostilities, the United States will, upon any engagement of forces, apply all of the provisions of the Geneva Conventions and the customary international law dealing with armed conflict. Further, the United States will accord prisoner of war treatment to any detained member of the Haitian armed forces. Any member of the U.S. armed forces who is detained by Haitian forces must be accorded prisoner of war treatment.
Modulated Inflammation by Injection of High-Mobility Group Box 1 Recovers Post-Infarction Chronically Failing Heart

Background— Inflammation plays an important role in the progress of adverse ventricular remodeling after myocardial infarction. High-mobility group box 1 (HMGB1) is a nuclear protein, which has recently been uncovered to also act as a modifier of inflammation when released. We hypothesized that HMGB1 injection could preferentially modulate local myocardial inflammation, attenuate ventricular remodeling, and subsequently improve cardiac performance of postinfarction chronic heart failure. Methods and Results— Three weeks after left coronary artery ligation, HMGB1 (2.5 &mgr;g) or PBS was intramyocardially injected into rat hearts. At 28 days after injection, left ventricular ejection fraction was significantly improved after HMGB1 injection compared to PBS (39.3±1.4 versus 33.3±1.8%; P<0.01). Accumulation of CD45+ inflammatory cells, two thirds of which were OX62+ dendritic cells, in the peri-infarct area was significantly attenuated by HMGB1 injection. Dramatic changes in the expression of major proinflammatory cytokines were not detected by microarray or RT-PCR. Adverse ventricular remodeling including cardiomyocyte hypertrophy (cardiomyocyte cross-sectional area; 439±7 versus 458±6 &mgr;m2; P<0.05) and extracellular collagen deposition (collagen volume fraction; 11.9±0.4 versus 15.2±0.6%; P<0.01) was attenuated by HMGB1 injection. Analyses of signal transduction pathways revealed that HMGB1 injection activated ERK1/2, but not p38, Akt, and Smad3. Cardiac regeneration and neovascularization were not observed. Conclusion— HMGB1 injection modulated the local inflammation in the postinfarction chronically failing myocardium, particularly via reducing the accumulation of dendritic cells. This modulated inflammation resulted in attenuated fibrosis and cardiomyocyte hypertrophy, which thereby improved global cardiac function. These data suggest that HMGB1 may be valuable for the chronic heart failure treatment.
A novel approach for estimating the omitted-citation rate of bibliometric databases with an application to the field of bibliometrics

One of the most significant inaccuracies of bibliometric databases is that of omitted citations, namely, missing electronic links between a paper of interest and some citing papers, which are (or should be) covered by the database. This paper proposes a novel approach for estimating a database’s omitted-citation rate, based on the combined use of 2 or more bibliometric databases. A statistical model is also presented for (a) estimating the “true” number of citations received by individual papers or sets of papers, and (b) defining an appropriate confidence interval. The proposed approach could represent a first step towards the definition of a standard for evaluating the accuracy level of databases.
Multiple-model adaptive control of an air heating fan using set-valued observers

This paper addresses the problem of controlling the temperature of an air heating fan with an unknown flow input rate. This time-varying uncertainty in the dynamics of the plant significantly reduces the performance of the closed-loop system, if a single (fixed) non-adaptive controller is used. Moreover, the average temperature of the air flowing through the system, that can be seen as an offset on the corresponding dynamics, is also (slowly) time-varying and highly dependent on the ambient temperature. Therefore, an alternative approach to this problem is proposed, by resorting to a novel multiple-model adaptive control methodology that relies on set-valued observers to identify the operating region of the plant. The suggested method is evaluated experimentally, demonstrating a loss of performance of about 2% when compared to the (unrealizable) perfect model identification scenario. As a shortcoming, the computational requirements due to the use of SVOs are considerably larger than the ones needed for an LTI non-adaptive controller.

The Formation and Role of Self Perceptions of Ability in Elementary Classrooms

The Elementary School Journal Volume 82, Number 5 o 1982 by The University of Chicago. All rights reserved. 00 13-5984/82/82 05-0003$0 1.00 In an effort to understand better the factors influencing children's performance in school, the relation of ability perceptions to academic achievement has been a topic of concern for many investigators (e.g., Bar-Tal 1978; Covington and Omelich 1979a, 1979b; Weiner 1979; Parsons, in press). Their formulations have been guided by attribution theory (i.e., Weiner et al. 1971), which proposes that an individual's interpretation of the causes of success and failure influences future achievement-oriented behavior. One of the most consistent findings in this tradition is that, if individuals believe that their successful completion of tasks is due to their own abilities, then they will be likely to attempt similar endeavors in the future because they expect to do well and feel good about their accomplishments. They will be less likely to do so if they believe achievement is due to other factors, like luck or ease of assignment. Consequently, this theory postulates that ability perceptions mediate achievement behavior. While there is a great deal of theory and research to support this view (see Weiner [1980] for a review), much of it results from studies using adult subjects in a laboratory setting. Several features of the work may limit the applicability of findings based on this approach to the classroom. First, there are developmental differences in children's cognitive capabilities that influence the formation and operation of ability perceptions. Second, in the natural context of the classroom the ecological validity of experimental results is questionable because the genesis and effect of perceptions may be quite different outside the
Jungck-Khan iterative scheme and higher convergence rate

In this paper, we continue the theme of analytical and numerical treatment of Jungck-type iterative schemes. In particular, we focus on a special case of Jungck-Khan iterative scheme introduced by Khan et al. [Analytical and numerical treatment of Jungck-type iterative schemes, Appl. Math. Comput. 231 (2014) 521–535] to get an insight in the strong convergence and data dependence results obtained therein. Our investigations show that this special case under different control conditions on parametric sequences provides higher convergence rate and better data dependence estimates as compared to the Jungck-Khan iterative scheme itself.
A Test of an Hypothesized Relationship between Learning Time and Amount Learned in School Learning

AbstractIt has been hypothesized that the degree of learning, other things being equal, is a simple function of the amount of time during which the pupil engages actively in learning. This hypothesis was tested with forty-eight students in an introductory psychology course. Classroom examinations were used to indicate amount learned; intelligence tests were used to indicate learning ability, and hours of study time reported by students were used to indicate learning time. When learning ability was controlled, statistically, the correlation between amount learned and learning time was statistically significant, r = . 30, a result which provides support for the original hypothesis. Considering the attenuating effect of indicants, it was concluded that learning time is a highly important variable which should be taken into account in investigations of classroom learning.
An Optimized CD4 T-Cell Response Can Control Productive and Latent Gammaherpesvirus Infection

ABSTRACT CD4 T cells are important for control of infection with murine gammaherpesvirus 68 (γHV68), but it is not known whether CD4 T cells function via provision of help to other lymphocyte subsets, such as B cells and CD8 T cells, or have an independent antiviral function. Moreover, under conditions of natural infection, the CD4 T-cell response is not sufficient to eliminate infection. To determine the functional capacities of CD4 T cells under optimal or near-optimal conditions and to determine whether CD4 T cells can control γHV68 infection in the absence of CD8 T cells or B cells, we studied the effect of ovalbumin (OVA)-specific CD4 T cells on infection with a recombinant γHV68 that expresses OVA. OVA-specific CD4 T cells limited acute γHV68 replication and prolonged the life of infected T-cell receptor-transgenic RAG (DO.11.10/RAG) mice, demonstrating CD4 T-cell antiviral activity, independent of CD8 T cells and B cells. Despite CD4 T-cell-mediated control of acute infection, latent infection was established in DO.11. 10/RAG mice. However, OVA-specific CD4 T cells reduced the frequency of latently infected cells both early (16 days postinfection) and late (42 days postinfection) after infection of mice containing CD8 T cells and B cells (DO.11.10 mice). These results show that OVA-specific CD4 T cells have B-cell and CD8 T-cell-independent antiviral functions in the control of acute infection and can, in the absence of preexisting CD8 T-cell or B-cell immunity, inhibit the establishment of gammaherpesvirus latency.

Boundary-Crossing Competence: Theoretical Considerations and Educational Design

This article provides a conceptual account and empirical analyses of the development of boundary-crossing competence—the ability to function competently in multiple contexts—using representative cases from two after-school programs with immigrant and low-socioeconomic status students. Our findings suggest that organizational designs that create networks of related communities of practice can provide opportunities for nondominant students to develop boundary-crossing competences through participation in expanded, horizontal—rather than hierarchal—systems of what Moll and colleagues have called “networked expertise. ” These new directions in understanding competence have important implications for improving learning designs for nondominant students.
Optimal Experience and Optimal Identity: A Multinational Study of the Associations Between Flow and Social Identity

Eudaimonistic identity theory posits a link between activity and identity, where a self-defining activity promotes the strength of a person’s identity. An activity engaged in with high enjoyment, full involvement, and high concentration can facilitate the subjective experience of flow. In the present paper, we hypothesized in accordance with the theory of psychological selection that beyond the promotion of individual development and complexity at the personal level, the relationship between flow and identity at the social level is also positive through participation in self-defining activities. Three different samples (i.e., American, Chinese, and Spanish) filled in measures for flow and social identity, with reference to four previously self-reported activities, characterized by four different combinations of skills (low vs. high) and challenges (low vs. high). Findings indicated that flow was positively associated with social identity across each of the above samples, regardless of participants’ gender and age. The results have implications for increasing social identity via participation in self-defining group activities that could facilitate flow.
Past anabolic-androgenic steroid use among men admitted for substance abuse treatment: an underrecognized problem?

BACKGROUND Recent reports suggest that anabolic-androgenic steroids (AAS) may cause mood disorders or dependence syndromes and may help to introduce some individuals to opioid abuse. At present, however, little is known about prior AAS use among men entering inpatient substance abuse treatment. METHOD We assessed lifetime AAS use in 223 male substance abusers admitted to a substance abuse treatment unit primarily for treatment of alcohol, cocaine, and opioid dependence. Subjects reporting definite or possible AAS use were then asked to participate in a detailed semistructured interview that covered demographics, drug use history, and symptoms experienced during AAS use and withdrawal, and whether AAS use had helped introduce the subject to other classes of drugs. RESULTS Twenty-nine men (13%) reported prior AAS use, but this history was documented on physicians' admission evaluations in only 4 cases. Among 88 men listing opioids as their drug of choice, 22 (25%) acknowledged AAS use, versus only 7 (5%) of the other 135 men (p <.001). Twenty-four (83%) of the 29 AAS users were interviewed in detail. Seven (29%) of the men interviewed, all with opioid dependence, reported that they first learned about opioids from friends at the gym and subsequently first obtained opioids from the same person who had sold them AAS. Eighteen (75%) of the men interviewed reported that AAS were the first drugs that they had ever self-administered by injection, 4 (17%) reported severe aggressiveness or violence during AAS use, 1 (4%) attempted suicide during AAS withdrawal, and 5 (21%) described a history of AAS dependence. CONCLUSION Prior AAS use appears to be common but underrecognized among men entering inpatient substance abuse treatment, especially those with opioid dependence. AAS use may serve as a "gateway" to opioid abuse in some cases and may also cause morbidity in its own right.
The Social Life of Stories: Narrative and Knowledge in the Yukon Territory

In this theoretically sophisticated study of indigenous oral narratives, Julie Cruikshank moves beyond the text to explore the social significance of storytelling. Circumpolar Native peoples today experience strikingly different and often competing systems of narrative and knowledge. These systems include traditional oral stories; the authoritative, literate voice of the modern state; and the narrative forms used by academic disciplines to represent them to outsiders. Pressured by other systems of narrative and truth, how do Native peoples use their stories and find them still meaningful in the late twentieth century? Why does storytelling continue to thrive? What can anthropologists learn from the structure and performance of indigenous narratives to become better academic storytellers themselves? Cruikshank addresses these questions by deftly blending the stories gathered from her own fieldwork with interdisciplinary theoretical perspectives on dialogue and storytelling, including the insights of Walter Benjamin, Mikhail Bakhtin, and Harold Innis. Her analysis reveals the many ways in which the artistry and structure of storytelling mediate between social action and local knowledge in indigenous northern communities. Julie Cruikshank is a professor of anthropology at the University of British Columbia. She is the author of Life Lived Like a Story: Life Stories of Three Yukon Native Elders (Nebraska 1990), winner of the 1992 MacDonald Prize.
