The rate of cleavage of GTP on the binding of Phe-tRNA.elongation factor Tu.GTP to poly(U)-programmed ribosomes of Escherichia coli.

Interaction of Phe-tRNA.elongation factor Tu.GTP with poly(U)-programmed ribosomes containing an occupied P site can be described by a three-step kinetic mechanism. Initial binding is followed by the cleavage of GTP, and then a new peptide bond is formed. Rate constants controlling the first and third of these reactions are known, but only a lower limit for the rate constant of the cleavage step has been reported. We have determined this rate constant to be 20 s-1 at 5 degrees C, 30 s-1 at 15 degrees C, and 50 s-1 at 25 degrees C. This is much faster than the reverse step of the initial binding process and implies that the intrinsic accuracy of the ribosome in the initial selection step is sacrificed in favor of speed. The similarity of the kinetic and chemical mechanism of this GTP cleavage step with other nucleoside 5'-triphosphatases is discussed.
Strategic Planning as an Integrative Device

While alleviating the adverse effects of employees' pursuit of their subgroups' goals over organizational goals is important, finding ways to avoid them may be even more important. In this paper, we investigate whether strategic planning can be used to reduce organizational members' position bias, or the extent to which they direct their attention toward the immediate goals and priorities attached to their position. We examine the hypothesis that involving employees in the strategic planning process and communicating the agreed-upon priorities to them afterwards enhance goal convergence by attenuating position bias. We examine these questions in a sample of 164 manufacturing plants from five countries and three industries, where we asked middle-level managers to assess the importance of various organizational goals. We find that participation and communication function as complements to jointly reduce managerial position bias.
La socialización parental en padres españoles con hijos de 6 a 14 años

Parenting style in Spanish parents with children aged 6 to 14. The aim of this paper was to establish which parenting style of Spanish families is associated with optimum children's outcomes. A random Spanish sample of 1,103 parents of children and teenagers from 6 to 14 years of age, of whom 47% were females, reported on their child-rearing practices. Families were classified into 1 of 4 groups (authoritative, authoritarian, indulgent, or neglectful) based on the parents' answers. Socialization outcomes were 6 indicators of interpersonal relationship quality, 9 indicators of psychological adjustment, 7 indicators of personal competence, and 12 indicators of behavior problems. Results showed that indulgent and authoritative parenting styles were associated with better outcomes than authoritarian and neglectful parenting. Overall, our results supported the idea that, in Spain, the optimum parenting style is the indulgent one, as scores in the four sets of socialization outcomes among children and teenagers from indulgent families were always equal to, or even better than, the authoritative parenting style.
Prognostic tests for uterine torsion affected buffaloes

Twenty-five female buffaloes suffering from uterine torsion were presented to the clinic of Veterinary Gynaecology and Obstetrics, CVAS, Bikaner for treatment. Three times blood samples were obtained from 25 buffaloes with uterine torsion (at the time of presentation of the animal, 1 h and 24 h after fetal delivery) and 5 healthy buffaloes to investigate the relationship between concentrations of SGOT (serum glutamic oxaloacetic transaminase), SGPT (serum glutamic-pyruvic transaminase), Bilirubin, serum creatinine and blood urea nitrogen (BUN). The aim of this study was to investigate related alterations in these blood constituents. There were significant (P < 0.01) increases in SGOT, SGPT, Bilirubin, serum creatinine and BUN in the affected buffaloes, possibly due to high uterine tissue damage. It may be inferred that torsion may lead to imbalance in biochemical profiles that affect the proper functioning of the uterine musculature. Buffaloes subjected to uterine torsion are associated with hepatic and renal dysfunction. In conclusion, concentration of above parameters can be used as a prognostic indicator for the occurrence of uterine torsion in buffaloes.
Accuracy-Based Learning Classifier Systems: Models, Analysis and Applications to Classification Tasks

Recently, Learning Classifier Systems (LCS) and particularly XCS have arisen as promising methods for classification tasks and data mining. This paper investigates two models of accuracy-based learning classifier systems on different types of classification problems. Departing from XCS, we analyze the evolution of a complete action map as a knowledge representation. We propose an alternative, UCS, which evolves a best action map more efficiently. We also investigate how the fitness pressure guides the search towards accurate classifiers. While XCS bases fitness on a reinforcement learning scheme, UCS defines fitness from a supervised learning scheme. We find significant differences in how the fitness pressure leads towards accuracy, and suggest the use of a supervised approach specially for multi-class problems and problems with unbalanced classes. We also investigate the complexity factors which arise in each type of accuracy-based LCS. We provide a model on the learning complexity of LCS which is based on the representative examples given to the system. The results and observations are also extended to a set of real world classification problems, where accuracy-based LCS are shown to perform competitively with respect to other learning algorithms. The work presents an extended analysis of accuracy-based LCS, gives insight into the understanding of the LCS dynamics, and suggests open issues for further improvement of LCS on classification tasks.
Performance Evaluation of Mobile Networks Based on Stochastic Ordering of Markov Chains

The modeling of mobile networks is difficult because of the number of users and their mobilities. In this study, we present a new methodology based upon stochastic ordering of Markov chains in order to evaluate the performance measures in wireless networks. These kind of networks are based on cellular systems. The cellular systems use different frequency coverage in order to increase system capacity. During a communication, a user may move from one cell to another which is named the handover. We propose to compute the dropping handover probabilities. The system is represented by a continuous time Markov chain which is too large to be solved by a numerical method. Our approach is to define a new Markov chain with a smaller state space size, and which provides an upper bound for the dropping handover probabilities. We define an aggregation process based on the weak stochastic orderings in order to define the aggregated upper Markov chain. We have proved using the stochastic comparison that the aggregated Markov chain provides an upper bound for the dropping handover probabilities.

A Personality‐Competence Model of Opinion Leadership

Opinion leaders constitute a central consumer segment for targeted marketing strategies. By separating opinion leadership into a generalized and domain-specific component, this study examines the psychological profile of N = 417 consumers from Germany and incorporates opinion leadership into a hierarchical framework of human personality. Results emphasize two major sources of domain-specific opinion leadership (DSOL): personality in the form of a general, domain-independent influencer trait and competencies in terms of product-specific knowledge. Moreover, the study highlights a number of traits including the Big Five of personality, typical intellectual engagement, and general self-efficacy that form a distinct personality profile of DSOL. The effects of these personality traits on DSOL are partially mediated by generalized opinion leadership and objective knowledge.
The relationship between high-sensitive troponin T, neutrophil lymphocyte ratio and SYNTAX Score

Abstract Aim. Cardiac troponins are the most preferred biomarkers in the evaluation of acute coronary syndromes (ACS). The aim of our study was to examine the association between high sensitive troponin T (hs-TnT), and neutrophil to lymphocyte ratio (NLR) and the complexity of ACS assessed by SYNTAX Score. Methods and results. 287 patients who underwent coronary angiography were studied (215 male, mean age 62.0 ± 12.7 years). 133 patients were ST elevation myocardial infarction (STEMI), 154 patients were non-ST elevation (NSTE) ACS . The patients are divided to tertiles according to SYNTAX Score; SYNTAX Score ≤ 22 (n = 122) 22 < SYNTAX Score ≤ 32 (n = 120), and SYNTAX Score > 32 (n = 45). NLR was significantly correlated with SYNTAX Score in both STEMI and NSTE-ACS groups (r = 0.254, p = 0.003, r = 0.419 p < 0.001). Multiple linear regression analysis showed NLR predicted the angiographic severity of ACS assessed by SYNTAX Score in two groups (β = 0.231, p = 0.004; β = 0.232, p = 0.003). Hs-TnT was significantly correlated with SYNTAX Score in two groups (r = 0.327, p < 0.001; r = 0.430, p < 0.001). Multiple linear regression analysis showed hs-TnT was independent predictor of SYNTAX Score in STEMI and NSTE-ACS patients (β = 0.292, p < 0.001; β = 0.317, p < 0.001). Conclusion. Hs-TnT and NLR were significantly correlated with angiographic severity of ACS assessed by SYNTAX Score.
Hydroacoustic forcing function modeling using DNS database

A wall pressure frequency spectrum model (Blake 1971 ) has been evaluated using databases from Direct Numerical Simulations (DNS) of a turbulent boundary layer (Na & Moin 1996). Good agreement is found for moderate to strong adverse pressure gradient flows in the absence of separation. In the separated flow region, the model underpredicts the directly calculated spectra by an order of magnitude. The discrepancy is attributed to the violation of the model assumptions in that part of the flow domain. DNS computed coherence length scales and the normalized wall pressure cross-spectra are compared with experimental data. The DNS results are consistent with experimental observations.
Children Sexually Abused by Multiple Perpetrators

This study investigates familial characteristics, as measured by the Family Environment Scale, and characteristics of the initial abuse experience as risk factors for multiple sexual victimization. Subjects were 324 college women including 16 with a history of sexual abuse by more than one perpetrator, 146 with a history of sexual abuse by a single perpetrator, and 162 with no history of abuse. Multiple-perpetrator victims characterized their families as displaying less cohesion, less expressiveness, more conflict, and more hierarchical rigidity in rule-governed behavior than did either single-perpetrator victims or nonvictims. In addition, both multiple-perpetrator victims and single-perpetrator victims reported that their families displayed less organization than did nonvictims. Multiple-perpetrator victims were both more likely to be abused by an intrafamilial perpetrator at first abuse, and to be younger at the onset of the first abuse, than were single-perpetrator victims. Initial abuse characteristics were related to characteristics of later victimizations. It is suggested that family dysfunction and initial abuse characteristics may serve as risk factors for multiple victimization.
Drivers of service recovery performance : perceived organisational support, learning and psychological job outcomes

Service recovery is an under-researched area in theoretical and empirical terms (Smith, Bolton, and Wagner 1999). In particular, limited knowledge exists regarding the factors which have an impact on the service recovery performance of frontline employees (Boshoff and Allen 2000). This research draws on goal orientation theory, perceived organisational support theory and the literature on psychological job outcomes and service recovery, in order to investigate the drivers of service recovery performance. The major goals of this study are to determine the effect of learning goal orientation on service recovery performance and the impact of perceived organisational support on learning goal orientation. Additionally, the effect of both learning goal orientation and perceived organisational support on emotional exhaustion is investigated. These simultaneous relationships are empirically tested for the first time. Following a review of the key literature, an integrative conceptual framework comprising a set of hypotheses is proposed and empirically tested in the UK. A total of 740 frontline service employees from the catering industry (representing a response rate of about 32%) provide the data for the analysis. Confirmatory factor analysis (CFA) is employed to assess the fit of the seven measurement components of the model and structural equation modelling (SEM) is used to test the hypothesised path model. The findings provide academic insights that may open new fruitful avenues for further research. In particular, two unexpected results contradict the extant theory: job satisfaction has a negative impact on service recovery performance and emotional exhaustion has a positive impact on service recovery performance. The new empirical results reveal that learning goal orientation has a positive impact on service recovery performance. Additionally, perceived organisational support has a positive effect on learning goal orientation. Moreover, whereas perceived organisational support has a negative impact on emotional exhaustion, learning goal orientation is unrelated to emotional exhaustion. Finally, the findings provide several managerial implications for service marketing practitioners by offering them practical guidelines to develop and implement effective service recovery programmes. Suggestions are provided in terms of the best practices when recruiting and training frontline service employees.
El modelo tripartito: relaciones conceptuales y empíricas entre ansiedad, depresión y afecto negativo

En este estudio se han perseguido dos objetivos. El primero ha sido replicar la estructura factorial propuesta por el modelo tripartito de ansiedad y depresion postulado por Clark y Watson (1991a). El segundo objetivo ha sido presentar datos de validacion del Cuestionario Basico de Depresion (CBD) de Penate (2001), que se ha utilizado con el fin de medir depresion independientemente del factor general de afecto negativo propuesto por el modelo. Se administraron las pruebas (BDI, BAI y CBD) a 705 participantes. Se utilizo metodologia factorial exploratoria y confirmatoria con transformacion de Schmid y Leiman (1957), con el fin de verificar la importancia del factor general de afecto negativo y constatar en que medida este modelo es capaz de explicar la covariacion de los sintomas de ansiedad y depresion. Los resultados apoyan al modelo tripartito y la validez del CBD como instrumento especifico para evaluar la depresion.
A Block Model Suitable for Sparse Graphs

We introduce a new generative block model for graphs. Vertices (nodes) have mixed memberships in margin components, and edges arise from a multinomial defined over the cartesian product of the margin components. The model is able to represent block structures of “non-community” type, that is, it is able to model linkage between margin components. Compared to earlier mixed membership stochastic blockmodels which have a Bernoulli parameterization for the generation of links between each margin component pair, in the new model collapsed Gibbs samplers need to represent only those interactions with realized data in them, making possible large and sparse block models.
Communicative effectiveness as a function of accented speech

Five groups of accented seventeen‐year‐olds from Britain were matched for sex, regional membership, and attitude toward capital punishment for murder. These groups were presented with the same persuasive message against capital punishment. Four of the groups heard the message on tape in a different accent produced by a speaker adopting the matched‐guise technique; the fifth group was given a typescript of the message. The results showed that the greater the accent prestige of the communicator's voice, the greater the perceived quality of the argument. Only the nonstandard regional accented messages, however, changed listeners’ attitudes significantly in the predicted direction.
An empirical examination of personal learning within the context of teams

Summary Using a sample of 588 employees in 59 work teams, we tested a model that situates personal learning within the context of teams, viewing it as a joint function of teams' leadership climate (i.e., transformational leadership) and task characteristics (i.e., task routineness and task interdependence). Consistent with our hypotheses, we found that the positive relationships between transformational leadership climate and the two dimensions of personal learning (relational job learning and personal skill development) were moderated by the nature of the teams' tasks. Specifically, transformational leadership climate was more strongly associated with personal learning for members of teams working on tasks that were less routine, rather than more routine. However, no significant moderation was found for leadership climate and task interdependence. Our findings underscore the importance of taking into account the contextual conditions within which leadership influence occurs while also demonstrating the potential role that leaders can play in promoting employees' personal learning. Overall, our study bolsters theories that conceptualize adult learning as a transaction between people and their social environments and points to a practical need to match leadership styles with team task characteristics to unleash transformational leadership effects.

Household survey analysis of the impact of comprehensive strategies to improve the expanded programme on immunisation at the county level in western China, 2006–2010

Objective To evaluate interventions to improve routine vaccination coverage and caregiver knowledge in China's remote west, where routine immunisation is relatively weak. Design Prospective pre–post (2006–2010) evaluation in project counties; retrospective comparison based on 2004 administrative data at baseline and surveyed post-intervention (2010) data in selected non-project counties. Setting Four project counties and one non-project county in each of four provinces. Participants 3390 children in project counties at baseline, and 3299 in project and 830 in non-project counties post-intervention; and 3279 caregivers at baseline, and 3389 in project and 830 in non-project counties post-intervention. Intervention Multicomponent inexpensive knowledge-strengthening and service-strengthening and innovative, multisectoral engagement. Data collection Standard 30-cluster household surveys of vaccine coverage and caregiver interviews pre-intervention and post-intervention in each project county. Similar surveys in one non-project county selected by local authorities in each province post-intervention. Administrative data on vaccination coverage in non-project counties at baseline. Primary outcome measures Changes in vaccine coverage between baseline and project completion (2010); comparative caregiver knowledge in all counties in 2010. Analysis Crude (χ2) analysis of changes and differences in vaccination coverage and related knowledge. Multiple logistic regression to assess associations with timely coverage. Results Timely coverage of four routine vaccines increased by 21% (p<0.001) and hepatitis B (HepB) birth dose by 35% (p<0.001) over baseline in project counties. Comparison with non-project counties revealed secular improvement in most provinces, except new vaccine coverage was mostly higher in project counties. Ethnicity, province, birthplace, vaccination site, dual-parental out-migration and parental knowledge had significant associations with coverage. Knowledge increased for all variables but one in project counties (highest p<0.05) and was substantially higher than in non-project counties (p<0.01). Conclusions Comprehensive but inexpensive strategies improved vaccination coverage and caretaker knowledge in western China. Establishing multisectoral leadership, involving the education sector and including immunisation in public-sector performance standards, are affordable and effective interventions.
Efficient tensor completion: Low-rank tensor train

This paper proposes a novel formulation of the tensor completion problem to impute missing entries of data represented by tensors. The formulation is introduced in terms of tensor train (TT) rank which can effectively capture global information of tensors thanks to its construction by a well-balanced matricization scheme. Two algorithms are proposed to solve the corresponding tensor completion problem. The first one called simple low-rank tensor completion via tensor train (SiLRTC-TT) is intimately related to minimizing the TT nuclear norm. The second one is based on a multilinear matrix factorization model to approximate the TT rank of the tensor and called tensor completion by parallel matrix factorization via tensor train (TMac-TT). These algorithms are applied to complete both synthetic and real world data tensors. Simulation results of synthetic data show that the proposed algorithms are efficient in estimating missing entries for tensors with either low Tucker rank or TT rank while Tucker-based algorithms are only comparable in the case of low Tucker rank tensors. When applied to recover color images represented by ninth-order tensors augmented from third-order ones, the proposed algorithms outperforms the Tucker-based algorithms.
