Are Competitive Positioning and Quality of Administration Related to the Continuity

The objective of this article is analyse the relation of competitive positioning and quality of administration about the continuity of companies bound to Federacao das Associacoes Empresariais de Santa Catarina (Santa Catarina Federation Business Association), Brazil. In this context, aiming to get the best data reliability to be analysed, it was applied a questionnaire to 173 companies. For identifying the competitive positioning it was used the Porter’s typology (1986) and for quality of administration perceived, it was used a scale developed by Gimenez et al. (2011). The companies were analysed in three moments: firstly with all involved, then the companies with more than 10 years of existence and, by the end, only with the companies with more than 20 years of existence. The data were analysed by means of factor analyses to verify the relation between positioning and quality of administration with the continuity. The results show that the competitive positioning did not present relation to the continuity, only the quality of administration, represented by environmental monitoring, presented a significant and positive relation to the continuity.
Evaluation of Free Radical Scavenging Activity of Various Leaf Extracts fromKedrostis foetidissima (Jacq.) Cogn.

The present study was to compare the effect of in vitro free radical scavenging activity between the various leaf extracts (aqueous, methanol, acetone chloroform and petroleum ether) of Kedrostis foetidissima. The free radical scavenging activity was found to be high in methanolic extract for DPPH, hydroxyl, nitric oxide, superoxide,hydrogen peroxide(H2O2) radical in a concentration dependent manner followed by chloroform, aqueous, acetone and petroleum ether extracts. The metal chelating activity and reducing power ability was also similar as above. The content of total phenols, flavonoids and tannins was also found to be high in methanolic extract which may be correlated to its antioxidant activity. Thus the result suggests that the methanolic leaf extract of K.foetidissima could serve as a potential source of antioxidants and can be explored as a therapeutic agent in free radical induced diseases.
On the possibility of the 2011 Tohoku-oki earthquake reactivating Shinmoe-dake volcano, southwest Japan: insights from strain data measured in vaults

The Shinmoe-dake volcano in southwest Japan, which produced its first major eruption in 52 yr on 26 Jan- uary 2011 but had been quiescent since 1 March, re-erupted on 13 March. It was only two days after the occurrence of the M = 9.0 Tohoku-oki earthquake in eastern Japan. The coin- cidence of the two events raises the question of whether the earthquake triggered the volcanic activity. As a provisional but rapid assessment of this question, we examined high- resolution strain data at a site located 18 km from Shinmoe- dake. In terms of the Tohoku-oki earthquake, three points can be drawn from the strain data: (1) static strain changes were less than 0.05◊ 10 6 , which is too small to trigger an eruption; (2) the amplitudes of dynamic strain changes are on the order of 10 6 , which may trigger seismicity or volcanic eruption; and (3) strain rates were not accelerated, which in- dicates no significant change in magma pressure. Comparing these results with reports of other eruptions coincident with seismic events, and considering a scenario in which a seismic event triggered an eruption, we tentatively conclude that the eruption on 13 March was not a triggered event. However, this conclusion may be revised after analyzing seismic data.
TherMOOstat: Occupant Feedback to Improve Comfort and Efficiency on a University Campus

Author(s): Sanguinetti, A; Pritoni, M; Salmon, K; Morejohn, J | Abstract: Despite the significant amount of energy spent on Heating, Ventilation, and Air Conditioning (HVAC) at universities, thermal comfort conditions in campus buildings are frequently poor. Conventional HVAC management systems at universities are typically out of the hands of building occupants and facilities management departments have limited resources to involve them. These factors can lead to over-heating or over-cooling and undiagnosed mechanical issues. Previous research has shown that thermal comfort feedback, or participatory thermal sensing, can simultaneously improve energy efficiency and occupant comfort in university buildings. However, these studies have been limited to single campus buildings and restricted populations of occupants. The success, scalability, and sustainability of any participatory thermal sensing program is dependent upon ongoing participation that is meaningful to occupants and useful to facilities management. Therefore, research is warranted to explore patterns of voluntary participation, thermal comfort, and occupant satisfaction in extended, campus-wide deployments of participatory thermal sensing programs. The present research begins to address these gaps in the context of an 18-month, campus-wide deployment of TherMOOstat, a participatory thermal sensing app and HVAC management system at University of California, Davis.
Cholangiocarcinoma: the quest for a second-line systemic treatment

Biliary tract cancers (BTC) are a heterogeneous group of epithelial neoplasms, with a poor prognosis. Advanced BTC remains a challenging, non-curable disease. Gemcitabine plus platinum chemotherapy is the standard of care as first-line (L1) therapy in this setting. Beyond failure of L1, available evidence to guide therapeutic decisions is scarce. Data from phase III studies are lacking and there is no validated strategy to date. In this review, we provide an overview of the systemic therapeutic options that can be proposed and unsolved questions in the management of patients with advanced BTC in the second-line (L2) setting. Criteria to select which patients should receive L2 therapy are ill defined and reliable prognostic tools and models to help estimate individual patient survival at the beginning of L2 are needed. Chemotherapy, mainly fluoropyrimidine-based yields modest survival results. There is insufficient evidence level to recommend a specific L2 chemotherapy regimen, and anti-epidermal growth factor receptor and antiangiogenic agents failed to demonstrate any survival improvement in a non-selected patient population. In recent years, knowledge about BTC molecular heterogeneity has considerably increased with the advent of high-throughput genomic and transcriptomic analyses, opening new avenues for targeted therapies. Patients with BTC may be particularly good candidates for biomarker-driven therapy in clinical practice. Among the ongoing developments, targeting of FGFR and IDH mutations and immune therapies hold many promises for the next future. In future L2 clinical trials, patients should be carefully characterized and stratified according to prognostic factors, disease subtype, and genetic drivers.
Direct imaging of antiferromagnetic domains in Mn 2 Au manipulated by high magnetic fields

In the field of antiferromagnetic (AFM) spintronics, information about the N\'eel vector, AFM domain sizes, and spin-flop fields is a prerequisite for device applications but is not available easily. We have investigated AFM domains and spin-flop-induced changes of domain patterns in ${\mathrm{Mn}}_{2}\mathrm{Au}$(001) epitaxial thin films by x-ray magnetic linear dichroism photoemission electron microscopy (PEEM) using magnetic fields up to 70 T. As-prepared ${\mathrm{Mn}}_{2}\mathrm{Au}$ films exhibit AFM domains with an average size $\ensuremath{\le}1\ensuremath{\mu}\mathrm{m}$. Application of a 30 T field, exceeding the spin-flop field, along a magnetocrystalline easy axis dramatically increases the AFM domain size with N\'eel vectors perpendicular to the applied field direction. The width of N\'eel-type domain walls (DW) is below the spatial resolution of the PEEM and therefore can only be estimated from an analysis of the DW profile to be smaller than 80 nm. Furthermore, using the values for the DW width and the spin-flop field, we evaluate an in-plane anisotropy constant ranging between 1 and $17\phantom{\rule{0.28em}{0ex}}\mathrm{eV}/\mathrm{f}. \mathrm{u}. $.
Ornamental plants as climatic indicators of arthropod vectors

Abstract The importance and risk of vector-borne diseases (e.g., leishmaniasis, West Nile Virus, Lyme borreliosis) is going to increase in the European temperate areas due to climate change. Our previous studies have shown that the potential distribution of Leishmania infantum and some Phlebotomus (sand fly) species - a parasite of leishmaniasis, and its vectors - may be expanded even to the southern coastline of the Baltic Sea by the end of the 21st century. The lowland areas of the Carpathian Basin and the main part of Hungary are projected to be suitable for the studied sand fly vectors in the near future. It is important to find some indicator plants to examine whether the sand flies are able to live in a certain climate at a certain time. We studied several Mediterranean and Sub-Mediterranean plant species, and we found that the aggregated distribution of three ligneous species (Juniperus oxycedrus L., Quercus ilex L. and Pinus brutia Ten.) shows high correlation with the union distribution of five sand flies (Phlebotomus ariasi Tonn., Ph. neglectus Tonn., Ph. perfiliewi Parrot, Ph. perniciosus Newst. and Ph. tobbi Adler, Theodor et Lourie). Since these Mediterranean species are highly tolerant of the edaphic characteristics of the planting site, they may prove to be good indicators. The present and upcoming climate of Hungary is seen to be suitable for the selected indicator plant species, and it draws attention to and verifies the potential of the expansion of sand flies, which has been proved by some recent observations of the vectors in Southern Hungary.
Heterospecific sperm reduction in interspecific crosses between two closely related phytophagous ladybird beetles, Henosepilachna vigintioctomaculata and H. pustulosa (Coleoptera: Coccinellidae)

In interspecific crosses, a mismatch in internal physiological conditions between two species can reduce sperm viability in the interval from insemination to fertilization, leading to gametic isolation. Two closely related Japanese phytophagous ladybird beetles, Henosepilachna vigintioctomaculata and H. pustulosa, show several isolating barriers, including reduction in the number of heterospecific sperm in the female reproductive tract and low egg‐hatching rates in interspecific matings. However, the mechanisms of these two potential isolating barriers and the association between them are unknown. Here we investigated temporal changes in the number of sperm stored in the female reproductive tract and egg‐hatching rates in inter‐ and intraspecific crosses between these species. Although the number of sperm decreased after both inter‐ and intraspecific crosses, the reduction was more drastic in inter‐ than in intraspecific crosses for females of both species. Most of the sperm reduction occurred early on, during sperm transfer from the bursa copulatrix to the paired ampullae of the common oviduct (the sperm storage organs). These two species also demonstrated stably low egg‐hatching rates in interspecific crosses. Since the degree and timing of the sperm reduction did not correlate with egg‐hatching rates, the reduction in heterospecific sperm in interspecific crosses may not directly cause the low hatching rates. These two isolating barriers could be different expressions of the physiological mismatch and/or genetic incompatibility between gametes of these species.
A Resolved and Asymmetric Ring of PAHs within the Young Circumstellar Disk of IRS 48

For one decade, the spectral type and age of the ρ Oph object IRS-48 were subject to debate and mystery. Modeling its disk with mid-infrared to millimeter observations led to various explanations to account for the complex intricacy of dust holes and gas-depleted regions. We present multi-epoch high-angular-resolution interferometric near-infrared data of spatially resolved emissions in the first 15 au of IRS-48, known to have very strong polycyclic aromatic hydrocarbon (PAH) emissions within this dust-depleted region. We make use of new Sparse-Aperture-Masking data to instruct a revised radiative-transfer model, where spectral energy distribution fluxes and interferometry are jointly fitted. Neutral and ionized PAH, very small grains (VSG), and classical silicates are incorporated into the model; new stellar parameters and extinction laws are explored. A bright (42 L⊙) and hence large (2.5 R⊙) central star with Av = 12.5 mag and Rv = 6.5 requires less near-infrared excess: the inner-most disk at ≈1 au is incompatible with the interferometric data. The revised stellar parameters place this system on a 4 Myr evolutionary track, four times younger than the previous estimations, which is in better agreement with the surrounding ρ Oph region and disk-lifetime observations. The disk-structure solution converges to a classical-grain outer disk from 55 au combined with an unsettled and fully resolved VSG and PAH ring, between 11 and 26 au. We find two overluminosities in the PAH ring at color-temperatures consistent with the radiative transfer simulations; one follows a Keplerian circular orbit at 14 au. We show a depletion of a factor of ≈5 of classical dust grains up to 0.3 mm compared to very small particles: the IRS-48 disk is nearly void of dust grains in the first 55 au. A 3.5 MJup planet on a 40 au orbit can qualitatively explain the new disk structure.
The Role of Environmental Heterogeneity in Maintaining Reproductive Isolation between Hybridizing Passerina (Aves: Cardinalidae) Buntings

Hybrid zones are useful systems in which to investigate processes important in creating and maintaining biological diversity. As they are often located in ecotones, patterns of environmental heterogeneity may influence hybridization, and may also influence the maintenance of reproductive isolation between hybridizing species. Focusing on the hybrid zone between Passerina amoena (Lazuli Bunting) and Passerina cyanea (Indigo Bunting), located in the eastern Rocky Mountain/western Great Plains ecotone, we examined the relationship between population-pairwise differences in the proportion of hybrids and environmental variation. Models including environmental variables explained more of the variation in hybridization rates across the ecotone than did models that only included the geographic distance between sampling localities as predictor variables (63.9% and 58.9% versus 38.8% and 39.9%, depending on how hybridization was quantified). In the models including environmental variables, the amount of rainfall during the warmest quarter had the greatest explanatory power, consistent with a hypothesis that P. cyanea is better adapted to the mesic environments of eastern North America and P. amoena is better adapted to the xeric habitats of western North America. These results suggest that continued reproductive isolation between these species is mediated, at least partially, by differential adaptations to local environmental conditions.
Cellulose–Chitosan Antibacterial Composite Films Prepared from LiBr Solution

Cellulose and chitosan solutions were prepared in 60% LiBr and mixed with a different weight ratio. The washing and drying of the prepared cellulose–chitosan composite films were performed under identical conditions. The color of the liquefied mixtures and films was initially transparent but changed from colorless to brownish yellow depending on the ratio of chitosan in the solution. The cross section observed in the SEM results indicated that the film developed with a higher ratio of chitosan was more robust and possessed greater antibacterial properties. FT-IR analysis of the films showed that hydrogen bonds between cellulose and chitosan in composite films were successfully achieved and retained excellent mechanical properties. The proper ratio of chitosan in the cellulose solution can increase the tensile strength and improve the elongation of the films; however, the E-modulus property was consistently reduced. The antibacterial activity and mechanical properties of the films were greatly improved as the amount of chitosan in the film increased.
Uniqueness of the sum of points of the period five cycle of quadratic polynomials

It is well known that the sum of points of the period five cycle of the quadratic polynomial $f_{c}(x)=x^{2}+c$ is generally not one-valued. In this paper we will show that the sum of cycle points of the curves of period five is at most three-valued on a new coordinate plane, and that this result is essentially the best possible. The method of our proof relies on a implementing Gr\"obner-bases and especially extension theory from the theory of polynomial algebra.
Parental Report of Infant Language Skills: A Review of the Development and Application of the Communicative Development Inventories.

The Communicative Development Inventories (CDIs) are parent report measures of vocabulary and other aspects of language development in very young children. They have evolved over the past 20 years to be one of the most well recognised assessments of infant language. Of particular significance is the fact that the CDIs are the first measures of their kind to be widely translated and adapted for use in many different languages. The inventories have served a variety of functions including measuring early language acquisition, deriving normative data on language acquisition, and both identifying and describing children whose early language is significantly delayed. This review describes the development of the CDIs, summarises the volume of research that has been generated in a range of applications of the measures, and evaluates their current standing both as a research tool and as a clinical measure. Issues around the sensitivity and predictive value of the CDIs are also considered.
The Formation and Early Evolution of Young Massive Clusters

We review the formation and early evolution of the most massive and dense young stellar clusters, focusing on the role they can play in our understanding of star and planet formation as a whole. Young massive cluster (YMC) progenitor clouds in the Galactic Center can accumulate to a high enough density without forming stars that the initial protostellar densities are close to the final stellar density. For this to hold in the disk, the time scale to accumulate the gas to such high densities must be much shorter than the star formation timescale. Otherwise the gas begins forming stars while it is being accumulated to high density. The distinction between the formation regimes in the two environments is consistent with the predictions of environmentally-dependent density thresholds for star formation. This implies that stars in YMCs of similar total mass and radius can have formed at widely different initial protostellar densities. The fact that no systematic variations in fundamental properties are observed between YMCs in the disk and Galactic Center suggests stellar mass assembly is not strongly affected by the initial protostellar density. We review recent theoretical advances and summarize the debate on three key open questions: the initial (proto)stellar distribution, infant (im)mortality and age spreads within YMCs. We conclude: the initial protostellar distribution is likely hierarchical; YMCs likely experienced a formation history that was dominated by gas exhaustion rather than gas expulsion; YMCs are dynamically stable from a young age; and YMCs have age spreads much smaller than their mean age. Finally, we show that it is plausible that metal-rich globular clusters may have formed in a similar way to YMCs in nearby galaxies. In summary, the study of YMC formation bridges star/planet formation in the solar neighborhood to the oldest structures in the local Universe. [abridged]
Electrohydrodynamic Structuring of Colloidal Particles on Leaky Dielectric Drops

This Master's thesis shows experimentally how colloidal particles in leaky dielectric liquid drops are actively structured by applying a DC electric eld. Colloidal particles in small droplets with a diameter of 100 m show similar structuring to what has previously been observed on bigger drops (1 mm), showing ribbon formation, spinning domains and pupil eects. It is shown how electrohydrodynamic assembly of colloidal particles on a drop surface depends on the electric eld strength, and how this enables fast assembly of the particles. The particles used in the experiments are clay particles, layered double hydroxides and insulating beads. The layered double hydroxides show similar structuring to the clay particles. The results suggest that active con- trol of colloidal particles on leaky-dielectric drops by an electric eld can lead to new ways of producing Janus shells and other 'smart armoured' droplets.

CURIO : A Fast Outlier Clustering Algorithm for Large Datasets∗

Outlier (or anomaly) detection is an important problem for many domains, including fraud detection, risk analysis, network intrusion and medical diagnosis, and the discovery of significant outliers is becoming an integral aspect of data mining. This paper presents CURIO, a novel algorithm that uses quantisation and implied distance metrics to provide a fast algorithm that is linear with respect to dataset size and only requires two sequential scans of disk resident datasets. CURIO includes a novel direct quantisation technique and the explicit discovery of outlier clusters. Moreover, a major attribute of CURIO is its simplicity and economy with respect to algorithm, memory footprint and data structures.

Independent Component Analysis using a Geometric Approach

For the problem of independent component analysis we propose an alternative solution to determining $n$ independent sources from $n$ channels using a geometric approach. The resulting algorithm inherits many properties of the then applicable simplex algorithm, namely computational tractability even in high dimensions ($n geq 100$), and yields demixing estimates comparable to standard algorithms (e.g. FastICA) for extremely small sample sizes ($N = 50$). Our results are corroborated by demixing of a real world ECG data set from the PhysioNet database.
