Language models for keyword search over data graphs

In keyword search over data graphs, an answer is a non-redundant subtree that includes the given keywords. This paper focuses on improving the effectiveness of that type of search. A novel approach that combines language models with structural relevance is described. The proposed approach consists of three steps. First, language models are used to assign dynamic, query-dependent weights to the graph. Those weights complement static weights that are pre-assigned to the graph. Second, an existing algorithm returns candidate answers based on their weights. Third, the candidate answers are re-ranked by creating a language model for each one. The effectiveness of the proposed approach is verified on a benchmark of three datasets: IMDB, Wikipedia and Mondial. The proposed approach outperforms all existing systems on the three datasets, which is a testament to its robustness. It is also shown that the effectiveness can be further improved by augmenting keyword queries with very basic knowledge about the structure.
Abuse-Related Attributions and Perceptions, General Attributions, and Locus of Control in Sexually Abused Girls

The purpose of this study was to examine abuse-related attributions and perceptions, general attributions, and locus of control and their impact on psychological symptomatology in sexually abused girls. Seventy-seven abused girls ages 7 to 12 and 88 normal controls were administered the Children's Attributions and Perceptions Scale (CAPS), Children's Attributional Style Questionnaire (CASQ), and the Locus of Control Scale for children (LCSC). There were significant group differences on all of the CAPS subscales and the “bad event” factor of the CASQ, with the abused group endorsing significantly more abuse-related attributions and perceptions and general attributions than controls. Furthermore, correlational and regression analyses demonstrated that in the sexually abused group, abuse-related attributions and perceptions were the most significantly related to and predictive of self-reported psychological symptomatology. Clinical and research implications are discussed in the context of the evolving literature on those factors that effect the psychological adjustment of victimized children.
Optimization of secure embedded systems with dynamic task sets

In this paper, we approach embedded systems design from a new angle that considers not only quality of service but also security as part of the design process. Moreover, we also take into consideration the dynamic aspect of modern embedded systems in which the number and nature of active tasks are variable during run-time. In this context, providing both high quality of service and guaranteeing the required level of security becomes a difficult problem. Therefore, we propose a novel secure embedded systems design framework that efficiently solves the problem of run-time quality optimization with security constraints. Experiments demonstrate the efficiency of our proposed techniques.
Quasi-Experimental Design, Constituency, and Advancing Women’s Interests: Reexamining the Influence of Gender on Substantive Representation

Research investigating whether female legislators provide more effective substantive representation on women’s issues than their male colleagues faces a significant methodological hurdle. Models used to estimate the effect of gender on representation inevitably omit constituency variables that affect the character of legislators’ decisions and are also correlated with gender, potentially biasing the estimates of the effect of gender. Employing a quasi-experimental research design as an alternative strategy, the authors remove this hurdle and estimate the influence of gender on representation free from this potential bias. The authors find that gender does affect representation and observe critical mass effects.
From tourist motivations to tourist satisfaction

Purpose – This paper aims to explore the concept of push and pull satisfaction and relates it with a uni-dimensional measure of satisfaction. Design/methodology/approach – A factor structure is derived, comprising push and pull satisfaction factors which are related to the level of overall satisfaction. The empirical study was performed in Lisbon, one of the main cultural cities in Europe. Findings – Results suggest that overall satisfaction reflects the tourist assessment of push and pull dimensions of satisfaction. Furthermore, results also demonstrate that satisfaction arose within the opportunity to experience the cultural and social specificities of a destination considering the appropriate facilities. Based on the study findings, implications for management and marketing are presented. Research limitations/implications – This study comprises various methodological limitations mainly concerning the sample size that was restricted to 323 cases as well as it only considers the cultural city of Lisbon.
Preparing Hispanic Students for the Real World

Student learning is enriched by problem-based service learning (PBSL) projects. For Hispanic students, the learning that takes place in PBSL projects may be even more significant, although the research published in academic journals about client-based projects for Hispanic students is limited. This article begins to advance an understanding of how PBSL projects can enhance the learning of Hispanic students. Data were gathered from 5 business courses and approximately 127 students, predominantly Hispanic, who served as consultants for various business organizations.
Covert and overt orienting of attention to emotional faces in anxiety

Attentional biases for emotional faces were investigated in high, medium, and low anxiety groups (N = 54) using a probe detection task. Four types of facial expression (threat, sad, happy, neutral) were used to examine the specificity of the bias. Attentional bias measures were derived from manual reaction times (RTs) to probes and the direction of initial eye movement (EM) to the faces. The RT data indicated enhanced vigilance for threat rather than neutral faces in high and medium, but not low, state anxiety. The bias for negative faces appeared to be a combined function of stimulus threat value and the individual's anxiety level. The RT bias did not seem to depend on overt orienting, as many participants made few EMs. However, those who made frequent EMs to the faces showed concordance between the RT and EM bias measures, and so the RT measure of attentional bias for negative versus positive faces at 500 ms appears to provide a valid index of the direction of initial orienting to emotional stimuli. There was no evidence of an anxiety - related bias for happy faces (predicted by the emotionality hypothesis), nor a dysphoria - related bias for sad faces. However, increased dysphoria scores were associated with reduced attentiveness to happy faces.
Effects of electronic maps on wayfinding abilities of patients with mild Alzheimer disease

We explored the effect and the difference between types of navigation maps (north-up map versus track-up map), landmarks, and the map complexity on the wayfinding abilities of Alzheimer’s disease (AD) patients. Our study included 48 participants (12 patients with AD, 12 patients with mild cognitive impairment (MCI), and 24 normal elderly subjects). We developed a virtual maze with 3Dmax and an interface with Virtools. Our results showed that the wayfinding abilities were worse in the AD group compared with the MCI group and the normal elderly. However, with the support of track-up maps, the AD group and the MCI group had similar performance as the normal elderly. The time spent on wayfinding decreased when using less complex maps and maps with no landmarks. All cognitive tests which we performed were significantly correlated with wayfinding abilities. Our study helped to establish future electric navigation maps built for patients with cognition impairment.
Ab initio study of AlxMoNbTiV high-entropy alloys

The AlxMoNbTiV (x = 0–1.5) high-entropy alloys (HEAs) adopt a single solid-solution phase, having the body centered cubic (bcc) crystal structure. Here we employ the ab initio exact muffin-tin orbitals method in combination with the coherent potential approximation to investigate the equilibrium volume, elastic constants, and polycrystalline elastic moduli of AlxMoNbTiV HEAs. A comparison between the ab initio and experimental equilibrium volumes demonstrates the validity and accuracy of the present approach. Our results indicate that Al addition decreases the thermodynamic stability of the bcc structure with respect to face-centered cubic and hexagonal close packed lattices. For the elastically isotropic Al0.4MoNbTiV HEAs, the valence electron concentration (VEC) is about 4.82, which is slightly different from VEC ∼ 4.72 obtained for the isotropic Gum metals and refractory—HEAs.
Contraceptive efficacy and side effects of Implanon®

Objective To determine the efficacy and side effects of Implanon® used for long-term contraception. Material and method Prospective study of 80 patients who used Implanon® for long-term contraception between January 2004 and January 2006. Side effects, efficacy and removals were recorded. Results Amenorrhoea, infrequent bleeding and frequent bleeding were reported by 33 (41.25%), 19 (23.75%) and 14 patients (17.5%), respectively. Non-menstrual side effects comprised breast tenderness in 15 patients (18.75%), acne in eight (10%), headache and dizziness in three (3.75%); depressive mood disorders, pelvic pain and loss of libido were mentioned each by two of the women (2.5%). During the study period, Implanon® was removed from 20 participants. No problem was encountered during its placement or removal. Conclusion Patients considering use of Implanon® must be carefully selected and informed about its expected side effects before placement.
Use of factor analysis in Journal of Advanced Nursing: literature review.

AIM This paper reports a review analysing the use of factor analysis in papers in Journal of Advanced Nursing. BACKGROUND Factor analysis is a multivariate statistical method for reducing large numbers of variables to fewer underlying dimensions. There are several methods of factor analysis with principal components analysis being the most commonly applied. Factor analysis has been used by researchers in nursing for many years but the standards for use and reporting are variable. METHOD Papers using factor analysis in Journal of Advanced Nursing were retrieved from 1982 to the end of 2004. The search term 'factor analysis' was used in the CINAHL database and applied specifically to Journal of Advanced Nursing in December 2004. Retrieved papers were included in the review if they came from Journal of Advanced Nursing and used factor analysis as part of the method of the reported study. RESULTS One hundred and twenty-four papers were retrieved as a result of the initial search criteria of which 116 were from Journal of Advanced Nursing. Screening of papers for the use of factor analysis left 100 papers for review. Principal components analysis was the most commonly used method of factor analysis; Eigenvalues greater than one was the most commonly applied criterion for selecting the number of factors followed by orthogonal rotation to achieve simple structure. The majority of papers did not report the whole factor solution and there were papers that did not specify anything beyond the fact that they carried out factor analysis. Confirmatory factor analysis was rarely used and exploratory methods other than principal components analysis were also rarely used. CONCLUSIONS Factor analysis is quite commonly used in nursing research reported in Journal of Advanced Nursing. While some papers are exemplary there is room for improvement in the reporting of all aspects of factor analysis.
Comparing Poor, Minority Elementary Students' Interest And Background In Science With That Of Their White, Affluent Peers

Using survey data, poor, minority, inner-city elementary students were compared with White, affluent children regarding science information, science experiences, and personal preferences concerning science education. The students' perceptions of scientists, levels of disciplinary knowledge, sources of science information, voluntary science-related activities, and desired amounts of school science instruction were also investigated. The results, contrary to common expectations, indicated several areas where the two groups did not differ. The level of science knowledge was found to be higher among the White, affluent group. However, attitudes toward science were more positive, the current amount of instructional time devoted to science was greater, and a desire for more science instruction was evidenced among the inner-city, minority students.
Revising and Improving the African American Acculturation Scale

The African American Acculturation Scale (AAAS) was revised and improved with a sample of 520 African American adults. Items that some participants in prior studies found objectionable were dropped, and a new version of the scale was created by factor analyzing the remaining items. The revised AAAS (AAAS-R) consists of 47 items that no participant has objected to; these comprise eight new, empirically derived subscales (i.e., factors) that have high reliability and validity and correlate r = . 97 with the original 74-item version of the scale. It is strongly recommended that researchers interested in studying acculturation among African Americans use this new version of the scale.
Pustular Psoriasis in Childhood and Adolescence: A 20‐Year Single‐Center Experience

Pustular psoriasis (PP) is rare in children. The small number of reported cases makes deciding on treatment and follow‐up challenging. The current study was an evaluation of treatment approaches and courses of PP in 18 children diagnosed and followed over a 20‐year period. From 1992 to 2011 we treated 1,447 children with psoriasis, 18 of whom had PP. Follow‐up was 2 to 19 years. At the time of initial manifestation of PP, our patients were 1.5 months to 16 years old. Seven patients had a previous history of psoriasis vulgaris. Three children entered long‐term remission after one pustular attack, 10 developed psoriasis vulgaris, 2 are currently under treatment, and 3 were lost to follow‐up. Treatment with acitretin, cyclosporine, or methotrexate was efficacious and well tolerated. PP is rare, but according to our experience, it has a good prognosis in children.
Coping with work-family conflict: The reciprocal and additive contributions of personal coping and organizational family-friendly support

The aim of this study was to test three alternative models – additive, interactive, and reciprocal – of the relationship between personal coping strategies and formal organizational family-friendly supports in mitigating work-family conflict (WFC). Altogether 474 employees in Israel having a partner and children and representing diverse professions and organizations were surveyed. The additive model, that is, personal coping and organizational supports together, were associated with decreased WFC, received support. However, the reciprocal model was also supported, as WFC decreased when individuals perceived the investments between their efforts in personal coping strategies and the organization's efforts in organizational supports as equal. The interactive model, namely personal coping and organizational supports compensate each other in decreasing conflict, received marginal support. Nevertheless, in each model personal coping strategies proved a better approach to mitigating WFC than formal family-friendly supports. The findings suggest that the role of organizational support is important in decreasing WFC when employees lack the personal coping strategies required or when they perceive the organization's efforts to be unfair in relation to their own coping efforts.
An Ectosymbiotic Flatworm, Temnocephala chilensis, as Second Intermediate Host for Echinoparyphium megacirrus (Digenea: Echinostomatidae) in Patagonia (Argentina)

During a survey of parasites of the Patagonian freshwater crab Aegla neuquensis neuquensis, its ectosymbiont Temnocephala chilensis was found parasitized with an echinostomatid metacercaria with 43 collar spines. Of the 414 T. chilensis collected, 106 were parasitized with metacercariae of Echinoparyphium sp. Ovigerous adults of E. megacirrus were obtained from domestic chicks experimentally infected with metacercariae obtained from temnocephalans. This is the first record of temnocephalans being parasitized by digeneans.
The topology and polarization of subbeams associated with the ‘drifting’ subpulse emission of pulsar B0943+10 – VI. Analysis of an 8-h Giant Metrewave Radio Telescope observation

We report analysis of an 8-h observation of PSR B0943+10 at 325 MHz performed at the Giant Metrewave Radio Telescope (GMRT) in India. B0943+10 is well known for displaying regular subpulse drifting and two emission modes. We investigate the modal behaviour of B0943+10. By reconstructing an entire ‘B’ mode from two consecutive ‘B’ modes, we estimate that the pulsar spends roughly 7.5 h in the ‘B’ mode and about 2.2 h in the ‘Q’ mode, on average. Although the pulsar can switch modes within one pulse, the subpulse drift rate changes with a characteristic time of 1.2 h over the course of a ‘B’ mode. Under the subbeam carousel model we find the drift rate changes are produced by a 10 per cent increase in the average number of subbeams and a 16 per cent increase in the carousel circulation time. We speculate that under the partially screened gap model the increase in circulation time should be related to a small increase in the neutron star surface temperature.

Does the Relative Strength of Grouping Principles Modulate the Interactions between them?

Abstract This study examines the influence of the relative strength of grouping principles on interactions between the intrinsic principle of proximity and the extrinsic principle of common region in the process of perceptual organization. Cooperation and competition between intrinsic and extrinsic principles were examined by presenting the principle either alone or conjoined with another principle. The relative grouping strength of the principles operating alone was varied in two different groups of participants so that it was similar for one group and very different for the other group. Results showed that, when principles acting alone had different strengths, the grouping effect of the strongest principle was similar to that of the cooperation condition, and the effect of the weakest principle was similar to that of competing conjoined principles. In contrast, when the strength of principles acting alone was similar, the effect of conjoined cooperating principles was greater than that of either principle acting alone. Moreover, the effect of conjoined competing principles was smaller than that of either principle operating alone. Results show that cooperation and competition between intrinsic and extrinsic principles are modulated by the relative grouping strength of principles acting alone. Furthermore, performance in these conditions could be predicted on the basis of performance in single-principle conditions.
Evaluating blocking probability in distributors

A model for evaluating blocking probability in distribution networks is presented, and equations for computing blocking probability for the class of series-parallel networks are derived. The quotations are exact for pure series networks and approximate for parallel networks. The accuracy of the approximation is investigated by comparing the blocking probability computed using the equations to measured simulation data. The results indicate that for higher loads and larger switches the approximation is generally within 10% of the simulation results. <<ETX>>
Using Analogy to Help Young Children Understand

Summary Analogies offer conceptual models for supporting the development of understanding. Contrary to some expectations, there is growing evidence that young children can reason analogically. Much of this evidence comes from experiments intended to test psychological theories. This study aimed to gauge the practical potential of analogy in topics often considered by teachers difficult for young children to understand. Aspects of young children's understanding of current electricity were compared in two conditions, namely with and without an analogy (87 and 89 children, respectively; 6‐7 years of age). The results indicated that the analogy was of practical value in teaching for understanding. It is suggested that their bases be carefully prepared prior to teaching the target topic and that what is to be understood is modelled directly and is explicitly related to its equivalent in the topic. Further investigations to determine conditions for the effective use of analogies when teaching young children, wh.
Meaningful Mathematics Instruction

Many children have difficulty learning mathematics because of developmentally inappropriate instruction. The article discusses a number of recommendations by mathematics educators for making mathematics instruction more developmentally appropriate. More specifically, it suggests that instruction focus on understanding, not rote memorization of facts and procedures. It should entail active, purposeful learning and put less emphasis on direct instruction and paper-and-pencil work. Teachers should foster and build upon children's informal strengths rather than treating students as blank slates. They should link symbolic arithmetic to informal understanding. Moreover, instruction should promote reflection and discussion. With a developmental approach, even a traditionally difficult topic such as fractions can be meaningful, thought provoking, and interesting to children, including those labeled as learning disabled.
Elite Swimming Coaches’ Perceptions of Mental Toughness

Using the mental toughness framework of Jones, Hanton and Connaughton (2007), the authors interviewed thirteen highly-experienced swimming coaches in a two-part study to determine the specific mental toughness subcomponents present in mentally tough swimmers, and to examine the factors that led swimmers to develop mental toughness. Interviews were transcribed and analyzed using methods outlined by Creswell (2007). While confirming eleven of thirteen subcomponents of mental toughness previously identified by Jones et al. (2007), the participants identified (a) “coachability” and (b) “retaining psychological control on poor training days” as previously unidentified subcomponents of mental toughness. In the second part of the study, the authors identified six higher-order themes describing how both the coach and the swimmer acted to develop mental toughness in the swimmer. Implications for researchers, swimming coaches, and sport psychology consultants are discussed.
