The Resolved Stellar Populations in the LEGUS Galaxies1

The Legacy ExtraGalactic UV Survey (LEGUS) is a multiwavelength Cycle 21 Treasury program on the Hubble Space Telescope. It studied 50 nearby star-forming galaxies in 5 bands from the near-UV to the I-band, combining new Wide Field Camera 3 observations with archival Advanced Camera for Surveys data. LEGUS was designed to investigate how star formation occurs and develops on both small and large scales, and how it relates to the galactic environments. In this paper we present the photometric catalogs for all the apparently single stars identified in the 50 LEGUS galaxies. Photometric catalogs and mosaicked images for all filters are available for download. We present optical and near-UV color–magnitude diagrams for all the galaxies. For each galaxy we derived the distance from the tip of the red giant branch. We then used the NUV color–magnitude diagrams to identify stars more massive than 14 M⊙, and compared their number with the number of massive stars expected from the GALEX FUV luminosity. Our analysis shows that the fraction of massive stars forming in star clusters and stellar associations is about constant with the star formation rate. This lack of a relation suggests that the timescale for evaporation of unbound structures is comparable or longer than 10 Myr. At low star formation rates this translates to an excess of mass in clustered environments as compared to model predictions of cluster evolution, suggesting that a significant fraction of stars form in unbound systems.
A Capability-Based Framework for Open Innovation: Complementing Absorptive Capacity

We merge research into knowledge management, absorptive capacity, and dynamic capabilities to arrive at an integrative perspective, which considers knowledge exploration, retention, and exploitation inside and outside a firm's boundaries. By complementing the concept of absorptive capacity, we advance towards a capability-based framework for open innovation processes. We identify the following six ‘knowledge capacities’ as a firm's critical capabilities of managing internal and external knowledge in open innovation processes: inventive, absorptive, transformative, connective, innovative, and desorptive capacity. ‘Knowledge management capacity’ is a dynamic capability, which reconfigures and realigns the knowledge capacities. It refers to a firm's ability to successfully manage its knowledge base over time. The concept may be regarded as a framework for open innovation, as a complement to absorptive capacity, and as a move towards understanding dynamic capabilities for managing knowledge. On this basis, it contributes to explaining interfirm heterogeneity in knowledge and alliance strategies, organizational boundaries, and innovation performance.
Study on Experience of Industrial Accidents and Awareness Level for Beauty Product Safety of Beauty Industry Employee

This study compared data regarding industrial accidents and awareness level for beauty product safety for four main parts of beauty industry such as hair-care, nail-care, skin-care, and make-up. Major risk factors in beauty industry are dust, musculoskeletal disorders, and organic solvent of beauty product in order of percentage. The specific types of industrial accidents in beauty industry are mainly associated with musculoskeletal system such as cuts, sprain, and varicose vein. They are mainly compensated by personal budget. The awareness levels of chemical and heavy metal containment for beauty product by beauty industry employee were 77.2% and 59.1% respectively. Most employee confirmed only important items of labelling requirement of beauty product. Also, most employee did not understand MSDS(Materila Safety Data) for chemicals used in beauty industry. Only 38.1% of beauty industry employee has had safety education while most employee (73.6%) realized that they needed safety education. Also, safety education supervised by KOSHA(Korea Occupational Safety and Health Agency) was the most preferred. This study would be good basis for safe and healthy working environment of beauty industry employee.
The surface chemistry of divalent metal carbonate minerals; a critical assessment of surface charge and potential data using the charge distribution multi-site ion complexation model

The Charge Distribution MUltiSite Ion Complexation or CD–MUSIC modeling approach is used to describe the chemical structure of carbonate mineral-aqueous solution interfaces. The new model extends existing surface complexation models of carbonate minerals, by including atomic scale information on the surface lattice and the adsorbed water layer. In principle, the model can account for variable proportions of face, edge and kink sites exposed at the mineral surface, and for the formation of inner- and outer-sphere surface complexes. The model is used to simulate the development of surface charges and surface potentials on divalent carbonate minerals as a function of the aqueous solution composition. A comparison of experimental data and model output indicates that the large variability in the observed pH trends of the surface potential for calcite may in part reflect variable degrees of thermodynamic disequilibrium between mineral, solution and, when present, gas phase during the experiments. Sample preparation and non-stoichiometric surfaces may introduce further artifacts that complicate the interpretation of electrokinetic and surface titration measurements carried out with carbonate mineral suspensions. The experimental artifacts, together with the high sensitivity of the model toward parameters describing hydrogen bridging and bond lengths at the mineral-water interface, currently limit the predictive application of the proposed CD–MUSIC model. The results of this study emphasize the need for internally consistent experimental data sets obtained with well-characterized mineral surfaces and in situ aqueous solution compositions (that is, determined during the charge or potential measurements), as well as for further molecular dynamic simulations of the carbonate mineral-water interface to better constrain the bond lengths and the number plus valence contribution of hydrogen bridges associated with different structural surface sites.
Comprehensive Sonoanatomy Teaching Module to improve Neuraxial Block Performance of Trainees

Introduction: Ultrasound can increase accuracy in identifying intervertebral levels, leading to safer and more effective delivery of spinal anaesthesia. This pilot study reports on the implementation and evaluation of a training module designed to teach residents lumbar ultrasound for facilitated neuraxial block administration. Materials and methods: The module encompassed three methods of training: (1) verbal instruction; (2) unlimited access to an interactive laptop-based training application; and (3) instructor-guided lumbar ultrasound performed on a model for 1 hour per week for 4 weeks. Five residents were assessed following module training and after 6 months. Residents were assessed for the quality of their ultrasound scan and their ability to estimate the depth of the dura/ligamentum flavum in both transverse and paramedian views. In addition, an eight question survey was used to assess resident confidence before and after training. Results: Image quality and dura resolution showed no statistically significant changes immediately after training and at 6 months follow-up. Residents demonstrated an acceptable ability to estimate dura depth immediately after training; however ability decreased at 6 months follow-up, indicating a low retention of skill. Resident confidence in lumbar ultrasound for neuraxial technique increased remarkably after training and remained high at 6 months follow-up. Conclusion: Long-term practice in ultrasound for neuraxial technique is required to reinforce and retain skill. Results from this pilot study can be used to design a multicenter, full-powered investigation to better determine the impact of training in lumbar ultrasound for improved neuraxial block delivery.
A Confirmatory Factor Analysis of the Child Behavior Checklist: An Exploration of Age and Sex Differences.

This study explores the construct validity of the Child Behavior Checklist (CBCL) (Achenbach and Edelbrock, 1983). Due to the liberal application of the CBCL in child mental health settings, it is critical that the validity of the instrument be supported for specific sub-populations. In this study, we explore whether the factor structure of the CBCL is different for sex and age variations in a sample of 2628 children presenting for treatment at a mental health center in a midwestern city. Result suggest that the subscales of aggression and depression are invariant across sub-samples of the population.
A Career-History Analysis of Gender Differences in Publication Productivity among South African Academics

Decades of research on gender differences in academic publication productivity has as yet provided very little, if any, empirical support for the common sense understanding that a certain measure of incompatibility exists between being a mother and a productive academic researcher. In an attempt to start unravelling the complexity of this productivity puzzle in the South African context, data collected from Curriculum Vitae (CVs) are integrated with qualitative interview data. This methodological approach provides a detailed view of publication patterns, couched within the context of an in-depth perspective on the career histories of sixteen of the country’s top-performing academics. The study identifi es important ways in which women and men approach their early academic and family lives differently, with divergent consequences for their career publication productivity.
Effects of sleep-deprivation on decision-making and action selection

This thesis addresses neuroscience research focusing on the brain’s mechanisms underlying behavioral choice, or prioritization, and decision-making. The research has been conducted with Drosophila melanogaster, the fruit fly – a good model from both the behavioral and neural perspectives. This project specifically observes the co-regulation of sleep with two other behaviors – courtship and oviposition. The overlap between the sleep and courtship circuits in the brain should provide a good model for behavioral prioritization, and the interaction between sleep and ovipositional preference should provide a model for understanding the effects of sleep on decision-making. All three of these adaptive behaviors are well studied at the behavioral level among flies and humans, but not well understood at the neuronal levels. The data presented points toward a neurotransmitter called octopamine – the fly’s homolog of the human neurotransmitter norepinephrine as key in the co-regulation between sleep and decision-making circuitry in the brain. Further research should delve into this pathway for a better understanding of such neural mechanisms.
Document de treball 2001/5: Budget spillovers in a metropolitan area: typology and empirical evidence

We present a model for measuring spillovers resulting from local expenditure policies. We identify and test for three different types of budget spillovers: (i) benefit spillovers from the production of local public goods, (ii) externalities in crowding, caused by non-resident users of public facilities, and (iii) externalities from expenditure competition effects. In order to account for these types of spillovers, we specify a demand of public goods with interactions among local governments. The model is tested for different expenditure categories with a cross-section of data from municipalities of the metropolitan area of Barcelona. We find positive benefit spillovers in spending in Cultural and Sports facilities, and in Parks and Streets maintenance. Externalities in crowding appear in spending on Police, Cultural and Sports facilities, Parks and Streets maintenance, and Street cleaning, Water delivery and Sanitation. Spending on Social services seems to be affected by competition externalities, while there is no evidence of spillovers in the expenditure on General Administration. RESUMEN: Presentamos un modelo para medir los desbordamientos en las políticas locales de gasto. Identificamos y contrastamos tres tipos de efectos desbordamiento en el gasto: (i) desbordamiento en los beneficios derivados de la producción de bienes públicos locales, (ii) costes de congestión creados por los residentes en jurisdicciones vecinas, y (iii) externalidades en el gasto derivadas de la competencia fiscal. Con objeto de considerar los distintos tipos de desbordamientos, se especifica una función de demanda de bienes públicos con interacciones entre gobiernos locales. Las predicciones del modelo son constrastadas para seis categorías de gasto diferentes con datos de los municipios pertenecientes al área metropolitana de Barcelona. Los resultados identifican externalidades positivas en los gastos de Cultura y Deporte y en Urbanismo. Los costes de congestión surgen en el gasto de Policía, Cultura y Deporte, Urbanismo, y Bienestar Comunitario. El gasto en Servicios Sociales parece estar influido por la competencia fiscal, mientras que no se obtiene evidencia de efectos desbordamiento en el caso del gasto en Administración General.
On the precision of X-ray source parameters estimated from ROSAT data

The precision of the point source parameters, i.e. those for source position, source counts and source extension obtained via Maximum Likelihood Estimation from ROSAT data, is investigated. The various categories of error in X-ray observatories are identified. An analytic perturbation analysis is set forth. This means in the ROSAT case a perturbation analysis of the likelihood function with respect to the perturbed quantity being scrutinized. The background distribution and point spread function of the telescope-detector unit belong to these quantities. ROSAT observations are simulated and subjected to data analysis with the ROSAT software. The parameter space spanned by the point source parameters is explored in this way. Common summarizing statistics, namely mean value and standard error for the empirical distributions of the source parameters obtained in simulation runs, are taken as estimates for the unknown true precision counterparts. The precision for the errors of the source parameters as determined in the ROSAT data analysis are treated in the same way. In this sense, the source count imprecision is below 2 counts (for ROSAT typical sources and background), the directional positional precision below 2 �� ,a nd the source extent imprecision below 3 �� for the ROSAT PSPC detector. For the HRI detector, the positional precision figures are better. An alternative approach to the precision issue by cross correlating the ROSAT All-Sky Bright Source Catalogue with the optical TYCHO star catalogue is taken in order to assess the over-all precision. Inference on the positional accuracy for the ROSAT sources along with the quality of the accompanying ROSAT position errors is made. The positional errors determined in this way are about 8 �� larger than the simulation counterpart. This is in qualitative agreement with the 6 �� surplus added for the random attitude errors and all other known or less well known error sources. In this sense, the catalogue positional errors are compatible with the positional precision found in the simulations.
Reference dependence, consequentiality and social desirability in value elicitation: A study of fair labor labeling

High profile cases of exploitative labor practices have increased concerns over agricultural working conditions. However, it is unclear whether and to what extent the public is willing to trade-off fair working conditions for higher prices and food imports. We implement a large-scale survey to uncover Greek consumer preferences for a food labeling system that certifies fair working conditions for the workers employed at all production stages of agricultural production. Empirical findings from several disciplines suggest that results from contingent valuation surveys can be susceptible to hypothetical bias, social desirability bias, and lack of consequentiality. To test these issues, we use the ‘cheap talk’ method (Kling et al., 2012), Lusk and Norwood’s (2009b) Inferred Valuation (IV) method and the consequentiality scripts employed in Vossler and Evans (2009) and Vossler and Watson (2013). We also test predictions of reference dependent theory by testing whether framing the valuation question as an ‘Equivalent Loss’ (EL) differs from classical ‘Willingness-to-pay elicitation’ (WTP). We collected responses from more than 3,800 consumers in the cities ∗Lecturer, Department of Agricultural Economics & Rural Development, Agricultural University of Athens, Iera Odos 75, 11855, Greece, e-mail: adrihout@aua.gr. †PhD candidate, Department of Agricultural Economics & Rural Development, Agricultural University of Athens, Iera Odos 75, 11855, Athens, Greece, e-mail: avas@aua.gr. ‡Regents Professor and Willard Sparks Endowed Chair, Department of Agricultural Economics, Oklahoma State University, Stillwater, OK 74078, USA, e-mail: jayson.lusk@okstate.edu. §Professor and Tyson Endowed Chair, Department of Agricultural Economics & Agribusiness, Division of Agriculture, University of Arkansas, Fayetteville, AR 72701, USA, and Adjunct Professor, Norwegian Agricultural Economics Research Institute and Korea University, e-mail: rnayga@uark.edu.
Damping profile of standing kink oscillations observed by SDO/AIA

Aims: Strongly damped standing and propagating kink oscillations are observed in the solar corona. This can be understood in terms of mode coupling, which causes the wave energy to be converted from the bulk transverse oscillation to localised, unresolved azimuthal motions. The damping rate can provide information about the loop structure, and theory predicts two possible damping profiles. Methods: We used the recently compiled catalogue of decaying standing kink oscillations of coronal loops to search for examples with high spatial and temporal resolution and sufficient signal quality to allow the damping profile to be examined. The location of the loop axis was tracked, detrended, and fitted with sinusoidal oscillations with Gaussian and exponential damping profiles. Results: Using the highest quality data currently available, we find that for the majority of our cases a Gaussian profile describes the damping behaviour at least as well as an exponential profile, which is consistent with the recently developed theory for the damping profile due to mode coupling.
Differences in electrodermal activity between a night of recovering sleep compared to a night of poor sleep induced by partying: an explorative study

The present study aimed at acquiring more knowledge about electrodermal activity in relation to sleep research. Polysomnography has been the gold standard in sleep research. However, lots of limitations go along with this method as for example being (almost always) bound to a laboratory. EDA is a measurement known since over one hundred years already, but has not been used frequently in sleep research yet. Since this measurement can bring many advantages into sleep research, more should be known about it in this conjunction. The differences in EDA have been compared between a night of recovering sleep and a night of disturbed sleep which was induced by partying. It was expected that the average SCL as well as number of SCR’s and total amplitude of SCR’s would be higher in a night of good sleep compared to a night of poor sleep. This was measured by means of the Q-Sensor which needed to be worn around the wrist by participants during the particular nights. Moreover, participants had to perform a vigilance task the following morning, were asked to fill in subjective questionnaires (KSS and PSQI) and to keep a sleep diary. This included subjective ratings of sleep quality for the four nights of the experiment. The results of the study confirmed the hypothesis concerning SCL, but not for the number of SCR and total amplitude of SCR’s. In addition, the results of the study reveal tendencies concerning the number of sleep storms that have been found in earlier studies. Further expectations that have been formulated had reference to hit-rate, miss-rate, false-alarm rate and sensitivity as well as reaction times on the vigilance task, at which only the hypothesis expecting a higher hit-rate after a night of good sleep was confirmed. The other hypothesis that had reference to the vigilance task could not be confirmed; the number of SCR’s, total amplitude of SCR’s and SCL were not found to be significantly higher during the vigilance task after a night of poor sleep compared to a good night. For future research, the number of SCR’s as well as the total amplitude of SCR’s are two concepts that should be studied more deeply, since great individual differences have been found. Moreover, it would be of advantage to find a manipulation assuring that people actually experience a night of poor sleep (accordance with subjective ratings and conditions assigned), to be sure that it really comes to a night of poor respectively good sleep. Then it would be possible to find out more about, amongst others, the tendencies concerning sleep storms which have been displayed in the current study.

Some Properties of Eucalyptus Wood Flour Filled Recycled High Density Polyethylene Polymer-Composites

The mechanical properties of eucalyptus wood flours (EWF) filled recycled high density polyethylene (HDPE) composites were investigated. First thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) analysis were conducted for recycled HDPE and EWF. Later the effects of EWF and maleic anhydride grafted polyethylene (MAPE) concentrations were studied. TGA analysis revealed that EWF and recycled HDPE started degrading around 230 °C and 280 °C, respectively. Melting temperature of the recycled HDPE was around 129 °C. Mechanical property evaluation showed that the increased concentration of EWF in polymer-composites reduced the tensile, flexural, and impact strength while increased the tensile and flexural modulus. The addition of small amount of MAPE coupling agent improved the tensile and flexural strength but this increase was leveled off at higher concentrations. Impact strength of the composites was reduced by the coupling agent. This study showed that polymer-composites can be manufactured utilizing recycled HDPE and eucalyptus wood flours in the process temperature range of 130-230 °C and could provide additional income for the lumber mills and promote the recycling of HDPE.
