UMBILICAL COILING INDEX AND ITS RELATIONSHIP WITH PERINATAL OUTCOMES

Aim: To evaluate any adverse perinatal outcomes associated with abnormal coiling of umbilical cord. Introduction:The primary objective of antenatal and intrapartum fetal surveillance both in early and late pregnancy is to prevent fetal death. One of the most important parts of the fetoplacental unit is the umbilical cord. It is now being studied in predicting the perinatal outcome. Materials and methods: This prospective study was conducted in Obstetrics and gynaecology department of a tertiary care hospital in Smt. Kashibai navale medical college and general hospital Narhe, Pune.Three hundred and fifty (350) umbilical cords of babies delivered either by vaginally or by lower segment caesarian section were examined. The umbilical coiling index was calculated by dividing the total number of coils by the length of the cord in cms. Subjects with umbilical coiling index below 10th percentile, between 10th and 90th percentile and above 90th percentile were defined as hypocoiled, normocoiled and hypercoiled respectively. It was then correlated with the following pregnancy outcomes: mode of delivery, preterm delivery, birth weight, meconium staining, Apgar score at 1 and 5 minutes, and neonatal intensive care unit (NICU) admissions. Hypocoiled cords were those having umbilical cord coiling index (UCI) less than 10th percentile and hypercoiled cords were those having UCI >90th percentile Statistical analysis was done . The results were statistically analysed by chi-square test. The p value â‰¤ 0.05 was considered statistically significant for all the analyses. Result: The mean UCI was 0.61 Â± 0.16. The hypocoiled umbilical cords (UCI < 10th percentile) were significantly associated with low birth weight, meconium staining, low Apgar score at 1 minute, and increased NICU admissions with a p-value < 0.05. Conclusion:Abnormall UCI(hypocoiling) are significantly associated with adverse perinatal outcome.
STRUCTURAL TRANSITIONS IN METAL NANOPARTICLES IN THE COURSE OF MELTING AND CRYSTALLIZATION HYSTERESIS: MOLECULAR DYNAMICS SIMULATION

Melting and crystallization hysteresis in gold and nickel nanoclusters was simulated using molecular dynamics and the tight-binding potential. It has been found that at the structural level the hysteresis in question corresponds to a smooth crossover from the liquid state to the crystalline one. The crossover in question is much more smooth for Au nanoparticles. In particular the coordination polyhedra distributions for Au nanoparticles have revealed not only basic fcc structure but also local hcp, ic (icosahedral) and pdp (a sort of decahedral) structures in a vicinity of the melting and crystallization temperatures.
Renormalization and universality of the Hofstadter spectrum

We consider a renormalization transformation R for skew-product maps of the type that arise in a spectral analysis of the Hofstadter Hamiltonian. Periodic orbits of R determine universal constants analogous to the critical exponents in the theory of phase transitions. Restricting to skew-product maps over circle-rotations by the golden mean, we find several periodic orbits for R, and we conjecture that there are infinitely many. Interestingly, all scaling factors that have been determined to high accuracy appear to be algebraically related to the circle-rotation number. We present evidence that these values describe (among other things) local scaling properties of the Hofstadter spectrum.
Low-Rank Approximations of Second-Order Document Representations

Document embeddings, created with methods ranging from simple heuristics to statistical and deep models, are widely applicable. Bag-of-vectors models for documents include the mean and quadratic approaches (Torki, 2018). We present evidence that quadratic statistics alone, without the mean information, can offer superior accuracy, fast document comparison, and compact document representations. In matching news articles to their comment threads, low-rank representations of only 3-4 times the size of the mean vector give most accurate matching, and in standard sentence comparison tasks, results are state of the art despite faster computation. Similarity measures are discussed, and the Frobenius product implicit in the proposed method is contrasted to Wasserstein or Bures metric from the transportation theory. We also shortly demonstrate matching of unordered word lists to documents, to measure topicality or sentiment of documents.
Osteologia pós-craniana e relações filogenéticas do titanossauro do Cretáceo Inferior Tapuiasaurus macedoi Zaher et al. 2011 Postcranial osteology and phylogenetic relationships of the Early Cretaceous titanosaur Tapuiasaurus macedoi

Herein is presented a comprehensive description of the postcranial skeleton and phylogenetic analysis of the Early Cretaceous titanosaurian Tapuiasaurus macedoi Zaher et al. 2011. Tapuiasaurus becomes a key-taxon due its completeness, shedding new lights on the first steps in the early titanosaur evolution. The new information gathered by this study reveals that the presacral vertebrae anatomy of Tapuiasaurus possesses the typical apomorphic lithostrotian morphology (e.g. single neural spines, absence of hyposphenehypantrum complex and aliform processes), whereas the architecture of fore and hindlimbs retains plesiomorphic characters, such as the presence of manual phalanges, as well as a pes with greater phalangeal count (=10). Contrasting with previous studies, the phylogenetic analysis retrieved Tapuiasaurus as an early lithostrotian, sister-taxon of the group formed by Yongjinglong datangi, from the Early Cretaceous of China, plus a relictual unnamed taxon from the Late Cretaceous of Minas Gerais State, the same region that in which Tapuiasaurus comes. The new recognized clade that would represents one of the first lithostrotian irradiations around the world, providing additional data that will help elucidate dispersion patterns in the group. This study reveals that the stepwise acquisition of the typical titanosaurian characters possesses a mosaic pattern, in which the apomorphic anatomy presented by the advanced titanosaurians was acquired along the last part of the Late Cretaceous, probably in the post Turonian time-interval (89.8 My). Key-words: Early Cretaceous, Titanosauria, Tapuiasaurus macedoi, Osteology, Phylogeny.
Dating violence among high school students

Purpose: Dating violence (DaV) among high school students was researched to accelerate talks among the stakeholders and establish measures. A cross-sectional questionnaire was conducted on 3,054 students in a prefecture located approximately 800km from Tokyo. Results The response rate of the questionnaire was 97.4%. 758 females (42%) and 609 males (52.1%) of the respondents reported they had experienced DaV assaults with significant difference in the sexual predilection (P=0.000). Respondents who reported themselves as victims of DaV were 33.4% females and 29.8% males. The types of reported DaV included verbal abuse (724 respondents), physical abuse (545 respondents) and sexual abuse (74 respondents). Among the 1,608 respondents who experienced DaV, 294 (21.2%) consulted with another person. Two hundred thirty three (233) of these respondents talked to their friends. The female/male ratio of those who reported their experiences showed a significant difference (p=0.000), 28% (female) and 11% (male). Males incline not to express their own feelings. Conclusions and Suggestions Over 40% of the students responding to this survey had experiences of DaV. Among them, over 80% of the victims had not shared their experiences with others. An interesting tendency of the male victims was found in this study. They were prone to receive physical abuse and also to not utilize consultation opportunities compared with the female victims. The trauma was, therefore, more likely to be embedded in their memories.
The case of nanotechnology

Purpose –The purpose of this paper is to explore two distinct subsets of dynamic capabilities that need to be deployed when pursuing innovation through inter-organizational activities, respectively, in the contexts of broad networks and specific alliances. The authors draw distinctions and explore potential interdependencies between these two dynamic capability reservoirs, by integrating concepts from the theoretical perspectives they are derived from, but which have until now largely ignored each other – the social network perspective and the dynamic capabilities view. Design/methodology/approach – The authors investigate nanotechnology-driven R&D activities in the 1995–2005 period for 76 publicly traded firms in the electronics and electrical equipment industry and in the chemicals and pharmaceuticals industry, that applied for 580 nanotechnology-related patents and engaged in 2,459 alliances during the observation period. The authors used zero-truncated Poisson regression as the estimation method. Findings – The findings support conceptualizing dynamic capabilities as four distinct subsets, deployed for sensing or seizing purposes, and across the two different inter-organizational contexts. The findings also suggest potential synergies between these subsets of dynamic capabilities, with two subsets being more macro-oriented (i.e. sensing and seizing opportunities within networks) and the two other ones more micro-oriented (i.e. sensing and seizing opportunities within specific alliances). Practical implications – The authors show that firms differ in their subsets of dynamic capabilities for pursuing different types of inter-organizational, boundary-spanning relationships (such as alliances vs broader network relationships), which ultimately affects their innovation performance. Originality/value – The authors contribute to the growing body of work on dynamic capabilities and firm-specific advantages by unbundling the dynamic capability subsets, and investigating their complex interdependencies for managing different types of inter-organizational linkages. The main new insight is that the “linear model” of generating more innovations through higher inter-firm collaboration in an emerging field paints an erroneous picture of how high innovation performance is actually achieved.
Geospatial Analysis of Rickettsial Species

Rickettsia species are obligate intracellular, arthropod-borne bacteria with a potential to cause multiple diseases including Rocky Mountain spotted fever (RMSF). Fleas, mites, and ticks serve as vectors for Rickettsia, but ticks are the primary vector of interest. RMSF and other rickettsial diseases have continued to gain importance in both human and veterinary medicine as RMSF is the most common tick-borne disease within the United States according to the Lyme and TickBorne Disease Research Center. A statewide citizen science project was utilized to determine the prevalence of Spotted Fever Group (SFG) Rickettsia in Arkansas. This project yielded results in 64 of Arkansas’s 75 counties. Results were utilized to determine prevalence in each of the represented counties, and then compiled into a geospatial representation of the data. It was determined that 34.32% of the ticks sampled were carriers of one or more rickettsial species. As the samples were divided by county, multiple counties were shown to have concerningly high exposure risk for SFG Rickettsia. There were six species of ticks represented throughout this study with Amblyomma americanum being the most common. There were also six species of Spotted Fever Group Rickettsia found within the samples. The small portion of ticks that underwent further analysis to determine the specific rickettsial species present, indicated that Rickettsia amblyommatis is likely the most common SFG Rickettsia in Arkansas.

The growth of the beech (Fagus sylvatica L.) stand on former agricultural land and its comparison with the naturally regenerated beech stand under comparable conditions

The issue of afforestation of non-forest land (e.g. agricultural land use) is currently a significant trend in land management. Sustainable development and maintenance of its ecological stability are among the reasons. The paper compares the 30-year development of the beech stand originated from artificial regeneration on former agricultural land in the area where the Ipeľ River rises in central Slovakia. Two methods of tending were used on three long-term research plots (LTPs) established at the age of 20 years: negative crown thinning, free crown thinning and the third LTP was left to its spontaneous development. The results confirmed the positive impact of tending on the development of these stands. Compared to naturally regenerated stands under comparable site conditions, their higher quantitative production was found. Regarding the qualitative production expressed by the number of trees of selective quality, the worst results were obtained on the control plot. Based on these results, it is recommended to pay more attention to the planting stock quality used for afforestation.
Modelling the Performance of Positive P/E firms and Negative P/E firms

This paper evaluates whether performance of positive P/E firms are significantly different from negative P/E firms. It also investigates the characteristics of positive P/E firms and negative P/E firms and determine whether the differences in characteristics are statistically significant. Both Mood Median test and Kolmogorov–Smirnov (K-S) test are used in this paper to examine the significance of results on data gathered for four Asian countries (China, Japan, South Korea and Singapore) for the period from 2004 to 2014. Findings of this study show that the performance between positive P/E firms and negative P/E firms was significantly different, especially in terms of stock price returns, EBIT margin, current ratio, cash, assets turnover, EPS growth, EBIT growth, revenue growth, and market capitalization. Such results are partly consistent with previous studies and contribute to this area of study by examining new characteristics between firms with positive P/E and negative P/E.
The Impact of Volume-Flexible Strategies on Performance in Health Services [ 004-0280 ]

This paper examines the impact of volume flexible strategies on organizational performance in academic medical centers. Volume flexible strategies represent a variety of methods where organizations use their portfolio of resources and capabilities to meet fluctuating customer demand while improving organizational performance. A path model is developed and tested based on a survey of academic medical centers. The results indicate that desired levels of volume flexibility have a positive impact on organizational capabilities that in turn, positively influence how internal sources of volume flexibility are leveraged. In addition, volume flexible capability and the use of internal strategies were found to have a positive influence on customerrelated performance that in turn, positively impacted financial and market share performance.
THE INFLUENCE OF THE COOLING EFFECT OF THE MOULDS ON THE QUALITY OF CASTINGS FROM ALUMINUM ALLOYS

The quality of cast components is largely dependent on the structure of the casting. With the achievement of optimal fine grain structure, without any internal or surface defects, it is possible to obtain sufficient mechanical properties of the casting. This effect can be achieved using mould with a higher cooling effect. The aim of this paper consists in evaluation of quality of the cast components from selected aluminum alloys using microstructure analysis and evaluation methods of physical properties of castings. Test samples from selected materials have been prepared by casting into the casting moulds with various cooling effect in order to achieve different conditions of solidification and cooling of the test samples.
On Optimal Weight Choice in a Frequentist Model Average Estimator1

The paradigm shift from the traditional approaches of model selection to model averaging is gaining ground in several disciplines, partly because of an obvious shortcoming of the former methods in that they tend to underreport variability and the benefit offered by the latter in that it helps account for the uncertainty inherent in the model selection process. Developing appropriate weight selection methods is an important and challenging problem for model average estimators. The model average estimator in this paper is from a linear regression model and we propose selecting the weights by minimizing the trace of an unbiased estimate of the model average estimator’ MSE. Asymptotic and analytic finite sample properties of the method are discussed. Simulations are carried out to study the behaviour of the model average estimator that results from the proposed weight selection method and comparisons are drawn with other weight choice schemes.
Caseload factors and the psychological well-being of community mental health staff

This study investigates whether perceived work characteristics can account for the associations between staff mental health and caseload factors. Seventy-nine multidisciplinary community mental health workers completed questionnaires measuring mental health and the work characteristics demand, control, support and role clarity. Caseload details including size, client diagnosis, gender and level of need, were obtained from service records. Multiple regression revealed that staff mental health was positively related to level of client need. This counter-intuitive result may be understood by the additional finding that level of client need was positively related to role clarity. Further, a higher proportion of clients with psychosis was associated with lower role clarity and higher demand. Staff mental health was also related to caseload size and client gender. It is concluded that work characteristics may help to account for some of the associations between caseload dimensions and staff mental health. Methodological limitations, implications for intervention and directions for future research are discussed.
Are kiwis saving enough for retirement? Preliminary evidence from SOFIE

Saving for retirement is an important decision for individuals and couples. The extent to which people are saving for retirement is a key element in formulating public policy toward saving and retirement incomes. Little or no insight into retirement savings can be gleaned from aggregate measures of household saving rates. It is the accumulation of wealth that is the critical indicator. For this information is needed on the assets and liabilities of households. This paper uses new data on assets and liabilities from the Survey of Family Income and Employment. We develop a formal life cycle model of wealth accumulation which allows us to estimate saving rates that people would need to have until retirement age in order to have an adequate income in retirement. We find that significant parts of the population aged 45-64 have made adequate provision. This is particularly true among the lower income groups where New Zealand Superannuation represents the majority of their retirement income. However, some people appear to be saving at rates below that needed to accumulate the required level of retirement wealth. Further work is underway to identify these groups and assess the magnitude of the shortfalls.

Information transmission around block trades on the Spanish stock exchange

This study investigates the informational effects of large transactions, or Block Trades (BT), in the Spanish Stock Exchange (SSE). In the open market period, this topic was not facilitated in the SSE as it was in other markets until 1998. The SSE thus provides a special environment for analysing the information transmission of these specific transactions. It is assumed that information can be better reflected by changes in true asset value, proxied by the midpoint of bid-ask best quotes. Therefore, we will look at changing true asset value orders instead of trades. Three different effects are studied around BTs: price, liquidity and information transmission. To capture them, three different endogenous variables are considered: true asset returns, relative spreads and adverse selection spread component. With this approach, no clear effects of BTs are found. The main result of the study is that there seems to be an increase in information asymmetries when one looks at the adverse selection spread component in some of the different subsample classifications (buyer, seller and sweeping BT), but there is no significant permanent effect on returns. This result could be related to insiders trading in the market. In sharp contrast with adverse selection evidence, a temporary decrease in bid/ask spread around BTs is also observed. These changes reflect temporary liquidity effects related to other spread components (order processing costs and inventory costs).
Trends in Azole Susceptibility of Candida albicans Isolated from Clinical Samples at a Tertiary Care Hospital in Georgetown, Guyana

Objective: This study sought to examine the frequency of isolation and azole susceptibility patterns of clinical Candida albicans isolates from a tertiary hospital in Georgetown, Guyana during a three-month period. Methods: Isolation and germ-tube identification of Candida sp were done by the hospital Microbiology Department. Further identification was made by assessing the colour and morphology of Candida isolates subcultured from SDA onto HardyCHROM Candida. Antifungal susceptibility testing and results interpretation were performed in accordance with the CLSI M44-A2 guidelines. Results: sixty-two non-duplicate isolates of Candida were analysed from multiple patient sources. The majority of these isolates were Candida albicans (56.5%), while the remainder (43.5%%) were non-C albicans species of which C glabrata (32.3%) and C krusei (8.1%) were the predominant species. 28.6% of the C albicans isolates were resistant to fluconazole and voriconazole, respectively, while 40% of the isolates were resistant to itraconazole. Conclusion: Azole resistance is a common phenomenon among C albicans isolates within the setting of the Georgetown Public Hospital Corp (GPHC).
SYSTEMATIC STOCHASTIC REDUCTION OF INERTIAL FLUID-STRUCTURE INTERACTIONS SUBJECT TO THERMAL FLUCTUATIONS

We present analysis for the reduction of an inertial description of ﬂuid-structure in- teractions subject to thermal ﬂuctuations. We show how the viscous coupling between the immersed structures and the ﬂuid can be simpliﬁed in the regime where this coupling becomes increasingly strong. Many descriptions in ﬂuid mechanics and in the formulation of computational methods account for ﬂuid-structure interactions through viscous drag terms to tranfer momentum from the ﬂuid to immersed structures. In the inertial regime, this coupling often introduces a prohibitively small time-scale into the temporal dynamics of the ﬂuid-structure system. This is further exacerbated in the presence of thermal ﬂuctuations. We discuss here a systematic reduction technique for the full inertial equations to obtain a simpliﬁed description where this coupling term is eliminated. This approach also accounts for the eﬀective stochastic equations for the ﬂuid-structure dynamics. The analysis is based on use of the inﬁnitesmal generator of the SPDEs and a singular perturbation anal- ysis of the backward kolomogorov PDEs. We also discuss the physical motivations and interpretation of the obtained reduced description of the ﬂuid-structure system.
