Comparison of effects on the anti-metastasis between isoliquiritigenin and glabridin

The aim of this study was to evaluate the anti-metastasis effects and the inhibition of the tube-like structure formation of human umbilical vein endothelial cells ECV304 of isoliquiritigenin and glabridin. The cell survival ratio of mice melanoma cells B16F1 was measured by SRB assay, the lethality rate was tested by trypan blue exclusion test. The survival ratio of human umbilical vein endothelial cells ECV304 were measured by SRB and AO/EB assays. The migration of B16F1 cells and ECV304 cells were measured by scratch wound assay. The matrix metalloproteinase-2 (MMP-2) activity in B16F1 cells culture medium was measured by gelatin zymography and ELISA methods. The inhibition on tube-like structure formation of human umbilical vein endothelial cells ECV304 were detected on artificial basilar membrane rebuilt by matrigel. Taken together, our data suggested that isoliquiritigenin and glabridin have strong anti-metastasis activities, in the same concentration, isoliquiritigenin has stronger function.
A distributed-based hospital information system model

In order to synchronize the information among the sections in the hospital information system, we create a model by using a distributed algorithm to achieve multicast. Based on the concept of the multicast algorithm theory, this paper discusses the distributed-based hospital information system model and its corresponding algorithms and data structure, and also simulates RPM algorithm by using its forwarding table, the time line and data packet caches to discuss the algorithm QoS solution.
Corporate Reputation: Meaning and Measurement

Corporate reputation has attracted interest from a wide range of academic disciplines. It is also a growing focus for business and media attention. This paper examines the construct of corporate reputation, first by untangling the terminological problems that have been caused by the interdisciplinary nature of much of the earlier work in the area. The construct of reputation and the allied constructs of image and identity are each reviewed. A structure is proposed in which the three constructs can be seen as labelling different but allied concepts. I then move on to consider how reputation has been measured. The paper uncovers considerable confusion in the use of what might appear to be basic terms and links this to a subsequent lack of grounded measurement tools in the sector, until relatively recently. With a clearer understanding of the construct of corporate reputation and the allied constructs of image and identity, researchers are now well placed to test the relationships widely claimed by practitioners between corporate reputation and other variables such as commercial performance and employee and customer satisfaction. The review ends by illustrating some of the issues that can be assessed from the basis of a clearer conceptualization of reputation and its measurement.
Moderators of shared leadership: work function and team autonomy

Purpose – Previous studies show that sharing leadership in teams offers potential performance benefits across various contexts. This paper aims to investigate moderators of the effectiveness of shared leadership. In particular, it seeks to explore the moderating effects of team work function – manufacturing versus knowledge team work – and team autonomy.Design/methodology/approach – In order to test the hypotheses, the authors conducted hierarchical regression analyses and ran moderated two‐way regression analyses using a field sample of 552 employees comprising 81 teams in a Danish manufacturing company.Findings – Contrary to expectations, the results demonstrated a non‐significant relationship between shared leadership and team performance. However, as expected, work function significantly moderated this relationship such that shared leadership exhibited a negative relationship with manufacturing team performance and a positive relationship with knowledge team performance. Moreover, team autonomy was po.
How subordinates’ machiavellianism and motives relate to satisfaction with superiors

This study explores the relationship between Machiavellianism and motives for communicating (pleasure, affection, inclusion, relaxation, control and escape) with satisfaction in the work place. Full-time employees (N=319) in a wide-variety of organizations reported their Machiavellianism and their interpersonal communication motives, as well as their satisfaction with their superiors. The study also seeks to answer the question if the motives mediate the influence of Machiavellianism on communication satisfaction with superiors. The results suggest that Machiavellianism shares a negative relationship with the affection motive, whereas escape, relaxation, and control motives share a positive relationship with Machiavellianism. Further analysis reveals that the affection motive mediates Machiavellianism in its relationship to satisfaction with superiors. The affection and pleasure motives share a direct relationship with satisfaction.
Towards Statistical Paraphrase Generation: Preliminary Evaluations of Grammaticality

Summary sentences are often paraphrases of existing sentences. They may be made up of recycled fragments of text taken from important sentences in an input document. We investigate the use of a statistical sentence generation technique that recombines words probabilistically in order to create new sentences. Given a set of event-related sentences, we use an extended version of the Viterbi algorithm which employs dependency relation and bigram probabilities to find the most probable summary sentence. Using precision and recall metrics for verb arguments as a measure of grammaticality, we find that our system performs better than a bigram baseline, producing fewer spurious verb arguments.
An integrated framework for retrieving and analyzing geographic information in web pages

Most of the information stored in web pages contains geographic context, such as place names, address, and coordinates. Such geographic information often contains great values and is worth retrieving and analyzing. Traditional search engine is limited in its capability of extracting meaningful geographic messages from mass of unstructured and textual source. Even with the retrieved geographic information, specific systems are still needed to show the spatial distributions of such data. This paper presents an integrated framework which can retrieve and analyze geographic information in web pages. This framework integrates the following core functions: geographic information retrieval; geocoding; spatial analysis and statistical analysis. We also demonstrate the effectiveness of this framework by employing it to retrieve and analyze the geographic information from a particular website.
Convergence and differentiation processes in Swiss higher education: an empirical analysis

The aim of this article is to contribute to the scholarly debate on differentiation processes in higher education, particularly in binary systems. The article builds on recent developments in institutional theory and organizational ecology regarding the nature of organizational forms, as well as on the mechanisms through which these forms impact on characteristics of individual higher education institutions, and highlight the role of isomorphic pressures and competitive differentiation. The approach emphasizes the relevance of segregation and blending processes between types of institution. An application to the relationship between the two main types in Swiss higher education confirms that these forces largely determine the dynamics of the populations, and that a distinction emerges between core features – which make the distinction between populations – and features for which individual strategies and local conditions are more relevant.
Inhibition of regain in body weight and fat with addition of 3-carbon compounds to the diet with hyperenergetic refeeding after weight reduction.

OBJECTIVE To investigate the efficacy of the 3-carbon compounds pyruvate and dihydroxyacetone (PD) in inhibiting reaccumulation of body weight and fat with refeeding after weight loss. DESIGN Longitudinal, in Clinical Research Center. After weight loss induced by hypoenergetic diet (1.3 MJ/d) for 3 weeks, refeeding with hyperenergetic diet (1.5 x resting energy expenditure) for 3 weeks. Refeeding diet randomized to contain PD or placebo (PL, polyglucose) as approximately 20% of energy intake. SUBJECTS 17 obese healthy women (n = 8 in PL group, n = 9 in PD group) (age: 22-60 y, weight: 72.5-139.7 kg). MEASUREMENTS Resting energy expenditure (REE), body composition (by bioelectrical impedance), nitrogen balance, serum proteins, biochemical profile, thyroid hormones, and insulin, before and after refeeding and weight and fat gain. RESULTS Refeeding with a hyperenergetic diet, weight gain was significantly less in patients receiving PD compared to placebo (1.8 + 0.2 kg vs 2.9 +/- 0.1 kg, P < 0.01). Body fat regain was also less with feeding of PD (0.8 +/- 0.2 kg vs 1.8 +/- 0.2 kg, P < 0.01). Body protein metabolism, as measured by nitrogen balance, serum protein concentrations and fat free mass, was similar in subjects consuming either PD or PL. CONCLUSIONS We conclude that 3-carbon compounds decrease weight gain and reaccumulation of body fat, without decreasing body protein gain, in obese subjects with hyperenergetic refeeding subsequent to weight loss.
Minimal Dirichlet Energy Partitions for Graphs

Motivated by a geometric problem, we introduce a new non-convex graph partitioning objective where the optimality criterion is given by the sum of the Dirichlet eigenvalues of the partition components. A relaxed formulation is identified and a novel rearrangement algorithm is proposed, which we show is strictly decreasing and converges in a finite number of iterations to a local minimum of the relaxed objective function. Our method is applied to several clustering problems on graphs constructed from synthetic data, MNIST handwritten digits, and manifold discretizations. The model has a semi-supervised extension and provides a natural representative for the clusters as well.
Beat Tracking using an Autocorrelation Phase Matrix

We introduce a novel method for estimating beat from digital audio. We compute autocorrelation such that the distribution of energy in phase space is preserved in a so-called autocorrelation phase matrix (APM). We estimate beats by computing individual APMs over short overlapping segments of an onset trace derived from the audio. Then an adaptation of Viterbi decoding is used to search the APMs for metrical combinations of points that change smoothly over time in the lag/phase plane. Because small temporal perturbations are seen as local movements on the APM, the Viterbi search can be bounded using a small 2D Gaussian window. The resulting algorithm jointly estimates tempo, meter and beat. As is always the case with Viterbi decoding, an online version is possible although best performance is achieved offline. We report results on an annotated dataset of 60-second musical segments.
List-based Monadic Computations for Dynamically Typed Languages

In this paper we propose a flexible and elegant design for list-based monadic ("karmic") computations in dynamically typed languages. Our approach is applicable to any dynamically typed language that supports lists, maps and higher-order functions. The design results in a clear, concise and largely language-independent syntax. We prove that our design adheres to the laws governing monads. We illustrate the use of the list-based monads with three examples: error handling in computations, stateful computations and parser combinators. We provide examples in the popular multi-paradigm language Perl, the object-oriented language Ruby and the functional dynamically typed language LiveScript.
GASPHOT: a tool for Galaxy Automatic Surface PHOTometry

In this paper we present a new tool for automatic, blind surface photometry of galaxies in deep and/or wide fields. The tool (GASPHOT) favors the robustness of results with respect to the details of galaxy modeling. To this aim, a single Sersic-law for the models and a hybrid 1D/2D approach for the best-fitting algorithm were adopted. GASPHOT is heavily based on SExtractor and provides luminosity, position angle and ellipticity profiles of galaxies extracted from CCD frames, as well as total magnitudes, half-light radii, and Sersic indices. These global parameters were obtained by simultaneously fitting the major and minor axis light growth curves of galaxies with a 2D flattened Sersic-law, convolved by the appropriate, space-varying PSF, which was previously evaluated by the tool itself. We tested GASPHOT on more than 15 000 simulated and real galaxies, obtaining robust upper limits for the errors of the global parameters of galaxies, even for non-Sersic profiles and blended objects. The GASPHOT performance was also compared with those of two popular alternative tools for a single component, Sersic law: GALFIT (Peng et al. 2002) and GIM2D (Marleau & Simard 1998). When dealing with ideal, isolated, and adeguately large galaxies, the three packages were all found to provide satisfactory results, apart from a definite bias in the GIM2D magnitudes. On the other hand, GASPHOT proved to be more robust than GALFIT and GIM2D for simulated, blended objects and for real galaxies. Moreover, at variance with GASPHOT and GALFIT, the quality (bias and scatter) of the fits provided by GIM2D rapidly declines as the galaxy size decreases.
Pathways to cooperation: the transformation of labour relations among leading South Korean firms

Abstract The presence of cooperative labour relations based on partnership among leading South Korean firms challenges prevailing theories that emphasize the role of national-level economic institutions and political alliances in shaping firm-level institutions. Economic liberalization and the failure of societal corporatist initiatives during the past decade indicate the absence of macro conditions favourable to the development of micro or firm-level partnership. Instead, partnership can be traced to political and economic factors operating at the micro or firm level. From case studies of five leading South Korean firms, this article will explain how partnership was forged out of micro-level interactions between cooperative institutions, power distributions and historical legacies. These firms’ cooperative ‘pathways’ reveal how micro-level institutions associated with coordinated capitalism may thrive within the macro framework of neo-liberalism. Given the economic importance of these leading firms, the institutional distinctiveness of Korean labour relations (and, by extension, the distinctiveness of Korean capitalism) is likely to persist despite the broader shift towards liberal capitalism.
On the uncertainty propagation: Why uncertainty on lie groups preserves monotonicity?

Researchers in the simultaneous localization and mapping (SLAM) community have taken for granted that uncertainty associated with the robot pose increases until the loop is closed. However, recently identified by [1], the monotonicity of uncertainty during exploration breaks when the robot returns to the initial position. In this paper, we propose a hypothesis that the monotonicity of pose uncertainty is preserved when the uncertainty is propagated on Lie groups rather than on Euclidean vector space. After deriving covariance propagated over Lie groups and Euclidean vector space, respectively, the monotonicity of uncertainty in each case is thoroughly investigated. Experiments with simulated and real-world scenarios on dead-reckoning validate our hypothesis on the monotonicity of uncertainty.
Effects of Script Availability on Social Behavior

The effect of increasing the availability of cognitive scripts on social behavior was investigated in three studies. In Study I male subjects read either a story describing a "boy-meets-girl" encounter or a control story. Those who read the boy-meets-girl story subsequently behaved in a much friendlier manner toward a female confederate than those who had read the control story, i.e., they smiled more, talked more, leaned forward more, and gazed at the confederate more. Study 2 replicated Study 1, except that subjects rated their mood after reading the stories. As predicted there were no differences between the conditions in mood, indicating that mood changes were not responsible for the behavioral effects. However, the behavioral effects in Study 2 were very weak. Study 3 attempted to explain why the behavioral effects in Study 2 were so much weaker than in Study 1. When there was a short delay (M = 4 minutes) between the time subjects read the story and met the confederate, subjects were significantly less friendly than subjects who had interacted with the confederate immediately after reading the story. It was concluded that making scripts available in memory can have powerful effects on behavior, although these effects appear to be quite temporally limited.
Development and Application of a Three‐Tier Diagnostic Test to Assess Secondary Students’ Understanding of Waves

This study focused on the development and application of a three‐tier multiple‐choice diagnostic test (or three‐tier test) on the nature and propagation of waves. A question in a three‐tier test comprises the content tier, which measures content knowledge; the reason tier, which measures explanatory knowledge; and the confidence tier, which measures the strength of conceptual understanding of the respondents. This paper presents results based on the responses of 243 Grade 10 students after they were formally instructed on the topic. The vast majority of the respondents showed an inadequate grasp of concepts about waves. Eleven alternative conceptions (ACs), which were expressed with confidence by more than 10% of the students, were identified; four of these ACs were expressed with high confidence.
Optimality and uniqueness of the Leech lattice among lattices

We prove that the Leech lattice is the unique densest lattice in R^24. The proof combines human reasoning with computer verification of the properties of certain explicit polynomials. We furthermore prove that no sphere packing in R^24 can exceed the Leech lattice's density by a factor of more than 1+1.65*10^(-30), and we give a new proof that E_8 is the unique densest lattice in R^8.
Vernacular and culturally based education in Oceania today: articulating global, national and local agendas

Much research has focused on a linguistic view of vernacular or culturally based education programmes, while the political aspects of creating such programmes have been less frequently addressed. Throughout Oceania, formal schooling is linked to the colonial encounter, and although the legacy of colonial education continues to shape current educational initiatives, school reforms are thus part of the efforts to reverse ongoing experiences of colonialism. Using a critical approach, and paying attention to the political situations that shape educational reforms, our article focuses on the tensions that make such reforms difficult to implement: tensions between State logics and indigenous claims, between ‘equal opportunity’ in school and discrimination based on race or culture; and between the various motives of vernacular education (patrimonial, political, pedagogical).
Changes in College Student Health: Implications for Academic Performance

This study investigated the longitudinal associations of health perceptions and behaviors with subsequent academic performance among college students. Multiple health perceptions and behaviors were assessed for 203 college students both at the beginning and end of an academic year. Students’ academic performance was also measured at the end of the year. Separate regression analyses were conducted for men and women to examine changes in health perceptions and behaviors as predictors of yearend performance. Significant gender differences were found for initial health symptoms, perceived stress, exercise, and nutrition. After controlling for prior achievement, increased binge drinking negatively predicted female students’ academic performance and feelings of success; increased tobacco use negatively predicted male students’ performance. Male and female college students appear to differ in the ways that their health changes over an academic year as well as how such changes impact their later academic performance. Implications for devising health promotion programs that specifically target male and female college students’ health risks are discussed.
A Yeast Two-Hybrid Screen for SYP-3 Interactors Identifies SYP-4, a Component Required for Synaptonemal Complex Assembly and Chiasma Formation in Caenorhabditis elegans Meiosis

The proper assembly of the synaptonemal complex (SC) between homologs is critical to ensure accurate meiotic chromosome segregation. The SC is a meiotic tripartite structure present from yeast to humans, comprised of proteins assembled along the axes of the chromosomes and central region (CR) proteins that bridge the two chromosome axes. Here we identify SYP-4 as a novel structural component of the SC in Caenorhabditis elegans. SYP-4 interacts in a yeast two-hybrid assay with SYP-3, one of components of the CR of the SC, and is localized at the interface between homologs during meiosis. SYP-4 is essential for the localization of SYP-1, SYP-2, and SYP-3 CR proteins onto chromosomes, thereby playing a crucial role in the stabilization of pairing interactions between homologous chromosomes. In the absence of SYP-4, the levels of recombination intermediates, as indicated by RAD-51 foci, are elevated in mid-prophase nuclei, and crossover recombination events are significantly reduced. The lack of chiasmata observed in syp-4 mutants supports the elevated levels of chromosome nondisjunction manifested in high embryonic lethality. Altogether our findings place SYP-4 as a central player in SC formation and broaden our understanding of the structure of the SC and its assembly.
“Stuck in the ICU”: Caring for Children With Chronic Critical Illness*

Objective: Neonatal ICUs and PICUs increasingly admit patients with chronic critical illness: children whose medical complexity leads to recurrent and prolonged ICU hospitalizations. We interviewed participants who routinely care for children with chronic critical illness to describe their experiences with ICU care for pediatric chronic critical illness. Design: Semi-structured interviews. Interviews were transcribed and analyzed for themes. Setting: Stakeholders came from five regions (Seattle, WA; Houston, TX; Jackson, MS; Baltimore, MD; and Philadelphia, PA). Subjects: Fifty-one stakeholders including: 1) interdisciplinary providers (inpatient, outpatient, home care, foster care) with extensive chronic critical illness experience; or 2) parents of children with chronic critical illness. Interventions: Telephone or in-person interviews. Measurements and Main Results: Stakeholders identified several key issues and several themes emerged after qualitative analysis. Issues around chronic critical illness patient factors noted that patients are often relocated to the ICU because of their medical needs. During extended ICU stays, these children require longitudinal relationships and developmental stimulation that outstrip ICU capabilities. Family factors can affect care as prolonged ICU experience leads some to disengage from decision-making. Clinician factors noted that parents of children with chronic critical illness are often experts about their child’s disease, shifting the typical ICU clinician-parent relationship. Comprehensive care for children with chronic critical illness can become secondary to needs of acutely ill patients. Lastly, with regard to system factors, stakeholders agreed that achieving consistent ICU care goals is difficult for chronic critical illness patients. Conclusions: ICU care is poorly adapted to pediatric chronic critical illness. Patient, family, clinician, and system factors highlight opportunities for targeted interventions toward improvement in care.
