Spectroscopic evidence of GE POL HPHT-treated natural type IIa diamonds

(HPHT) annealed nominally type IIa diamonds are presented, and these spectral characteristics are compared with those of untreated diamonds of similar appearance and type. Absorption spectroscopy reveals that any yellow coloration in such HPHT-treated diamonds is due to low concentrations of single nitrogen, which have not been observed in untreated type IIa diamonds. Laser-excited photoluminescence spectroscopy reveals the presence of nitrogen-vacancy centers in most, but not all, HPHT-treated stones. When these centers are present, the ratio of the 575:637 nm luminescence intensities offers a potential means of separating HPHT-treated from untreated type IIa diamonds. The total absence of luminescence may be another important indicator of HPHT treatment.
Multiscale pore‐network representation of heterogeneous carbonate rocks

A multiscale network integration approach introduced by Jiang et al. (2013) is used to generate a representative pore‐network for a carbonate rock with a pore size distribution across several orders of magnitude. We predict the macroscopic flow parameters of the rock utilising (i) 3‐D images captured by X‐ray computed microtomography and (ii) pore‐network flow simulations. To capture the multiscale pore size distribution of the rock, we imaged four different rock samples at different resolutions and integrated the data to produce a pore‐network model that combines information at several length‐scales that cannot be recovered from a single tomographic image. A workflow for selection of the number and length‐scale of the required input networks for the network integration process, as well as fine tuning the model parameters is presented. Mercury injection capillary‐pressure data were used to evaluate independently the multiscale networks. We explore single‐scale, two‐scale, and three‐scale network models and discuss their representativeness by comparing simulated capillary‐pressure versus saturation curves with laboratory measurements. We demonstrate that for carbonate rocks with wide pore size distributions, it may be required to integrate networks extracted from two or three discrete tomographic data sets in order to simulate macroscopic flow parameters.
Research spin-off firms: does the university involvement really matter?

Les entreprises spin-off de recherche (RSOs) sont largement reconnues comme une source d’opportunite cle pour le developpement potentiel des universites. Cet article vise a analyser le role des RSOs en partant de la relation qu’elles ont avec leur institut parent. L’objectif est de mesurer plus specialement l’importance - ou non - de l’implication des universites dans la nature et la reussite de telles entreprises. La recherche s’appuie sur des donnees empiriques originales collectees et constituees sur les RSOs italiennes. Le traitement systematique de ce materiau (statistique descriptive, analyse factorielle et de cluster) permet de valider les hypotheses de depart car il montre que la force de l’interet de l’universite envers une RSO a des consequences significatives sur l’orientation et la structure de l’entreprise. La recherche permet d’identifier plus precisement deux principaux groupes de RSOs que l’on peut qualifier d’open-oriented et autonomous-oriented.
seAsoNAL ANd dAiLY VAriABiLiTY oF CO 2 emissioNs From The czerWoNe BAGNo PeAT BoG iN BieBrzA NATioNAL PArk ( PoLANd ) *

12Abstract. The article describes the results of field studies carried out in the period from April 2013 to may 2014. The study concerned the assessment of the magnitude of co2 emissions from marsh soils in the area of czerwone Bagno peat bog, which is a part of the largest complex of peatlands in Poland. The authors used the closed chamber method to measure seasonal variability of net ecosystem co2 emission and drew attention to the impact of environmental factors (air temperature, air pressureandsoil moisture) on it. The highest values of average daily co2 emission (over 630 mg(co2)×m –2×h–1) were recorded in late spring and summer. Lowest values were obtained in late autumn and winter (in the range of 178–212 mg(co2)×m –2×h–1). The need for monitoringof peat bogin temperate latitudes is stressed due to the progressive process of peat soilsdrying which enables the release of large quantities of greenhouse gases – co2, ch4 – into the atmosphere.
Effect of Road Safety Education on Road Risky Behaviors of Spanish Children and Adolescents: Findings from a National Study

Background: Road Safety Education (RSE) is widely known as a reliable determinant of the future results for what concerns health and welfare and as an undisputable factor which contributes to the social behavior of individuals and to their mid- and long-term road safety outcomes. However, its development has been relatively scarce in most countries, a fact which has contributed to letting matters as delicate as traffic crashes, largely explained by road misbehaviors, continue to be a prevalent problem, thus affecting the health of the community. Objective: The aim of this study was to describe the relationship between demographic and RSE-related variables and the self-reported road risky behavior of Spanish students. Methods: For this cross-sectional study, a representative sample of 4062 (51.5% males and 48.5% females) participants attending primary (47.5%), secondary (40.7%), and high school (11.7%) was gathered through a national survey on RSE and road behaviors. Results: A set of significant associations between demographic factors, RSE variables, and self-reported road behaviors was found. Furthermore, Structural Equation Modelling (SEM) allowed us to establish that age and observed misbehaviors (positively), and attitudes towards road safety and risk perception (negatively), have a direct link with the road risky behavior of children and young people. The knowledge of traffic rules was not a significant predictor of road behavior. Conclusions: The results of this study show that, together with demographic factors such as age, RSE-related variables have an effect on the road behavior of children and young people. They also suggest the need for strengthening actions to be implemented in road safety (Road Safety Education) at scholar and community levels.
Developing Concept Learning Capabilities in the COGNET/IGEN Integrative architecture and Associated Agent-based Modeling and Behavioral Representation (AMBR) Air Traffic Control

Abstract : This report describes all Systems' efforts during Phase III and IV of the model comparison process of the Agent-based Modeling and Behavioral Representation (AMBR) program conducted by the Air Force Research Laboratory. Phases III and IV focused on modeling and simulating concept learning within the context of a simulated Air Traffic Control (ATC) work environment. all Systems extended the COGNET/iGEN framework used in prior AMBR phases, implementing a general capability to learn the conditions under which each of a disjunctive set of goals or actions should be taken. Deeper extensions to the system enabled the representation of memory decay, rehearsal, and proactive interference needed to model human learning performance. The Phase III and IV COGNET/iGEN model execution results were compared with the results of three other models (ACT-R, D-Cog, EPIC- Soar) and results collected from human trials. On most measures (accuracy, response time, workload) iGEN model results were indistinguishable from human performance and, overall, iGEN results provided a better fit to the human data than the other models tested.
The Consequences of Corruption on Economic Growth in Mediterranean Countries: Evidence from Panel Data Analysis

: This study attempts to assess the impact of corruption on economic growth in the Mediterranean countries, during the period from 1998 to 2007. Econometric analysis using panel regression has been adopted to test this effect. Individual effects models such as random effects model and fixed effects model were applied to the study sample of 160 observations, and to choose the suitable model, we implemented several tests. For our analysis, we used a basic model that includes the dependent variable GDP per capita as a factor of economic growth and the corruption perception index as the independent variable concerned. Then we completed the model with several standardized macroeconomic control variables mentioned above and applied the individual effects models. The outcomes illustrate that corruption has a negative impact on the selected Mediterranean countries’ economic growth.
Strategies for Obtaining Parental Consent to Participate in Research

Researchers recruiting samples of children through schools typically face considerable challenges in obtaining completed consent forms from parents. Because children whose parents do not return consent forms are not able to participate in research, parental nonresponse is a primary factor contributing to nonrepresentative samples. In this article, we describe a set of procedures used to obtain active parental consent for child participation that resulted in a 95% return rate or consent forms. Rates of return were similar across schools that varied according to both racial and socioeconomic composition.
Microplankton respiration and net community metabolism in a bay on the NW Mediterranean coast

The seasonal variation in the respiration and net community metabolism of microplanktonic communities was examined in the Bay of Blanes, a n exposed NW Mediterranean bay (NE Spanish coast) which receives intermittent inputs from a torrential river, based on estimates of respiration rates of microplanktonic communities obtained over 2 yr (March 1992 to March 1994). Community respiration rates (mean + SE = 5.232 + 0.9 pm01 O2 dm-Q-') ranged over 2 orders of magnitude, showing a distinct seasonal pattern, with the highest respiration rates in summer and late winter. Differences in respiration rate were independent of ambient temperature but were closely related (r = 0.81) to the biomass of heterotrophic microplankton, which was dominated by bacteria and heterotrophic ciliates. The microplankton community in the Bay of Blanes tended to be net heterotrophic on the annual time scale, with demands exceeding autochthonous production. Net daily autotrophic metabolism was only observed during per~ods of very low respiration rates, and heterotrophic organisms played a dominant role in the metabolism of the NW Mediterranean littoral community studied, as evidenced by a strong correlation between net community metabolism and respiration rates. There was substantial interannual variation in metabolic rates between years, with average respiration rates in the first year twice as high as those in the second year (6.816 + 1.728 and 3.672 t 0.374 pm01 O2 dm-3 d.', respectively). This resulted in a more heterotrophic net daily community metabolism during the first than during the second year (-1.258 + 0.94 and 0.978 * 0.344 pm01 O2 dm-= d-', respectively). The net heterotrophic nature of the microplanktonic community in the Bay of Blanes indicates that carbon demands should be partially satisfied from inputs from land, consistent with the much higher rainfall in the first, compared to the second, year. Variability in rainfall and the associated differences in carbon inputs from land are, therefore, major sources of interannual differences in the microplanktonic metabolism of the NW Mediterranean littoral.
Added to the Figure caption Reviewer comment of Niko Wanders

I recommend to add the number of climate classifications used in the paper (four) rather than stating just ‘different’ or ‘several’ climate classification systems (more informative for the reader). Then it follows more natural to refer to e.g. the aridity index or e.g. the Köppen-Geiger (please add e.g. to the latter in line 25 of the abstract). This also applies to other parts of the text, for instance: P12, L5: ‘of all classes of the four climate . ’ P16, L3: ‘Four different climate classification systems and five individual controls were . ’ P22, L2: ‘This study evaluated four different . ’ Applied this suggestion in the abstract (page 2), the suggested lines and in several other cases. Also mentioned it for the individual controls (i.e., five individual controls). P3, L23: I find it a bit confusing to list the aridity index here (rather it should list its parameters). Replaced Aridity index with precipitation and (potential) evaporation P8, L13: I suggest adding some more information regarding the calculation of the BFI as its use in seasonal snow regime (using the entire record) has been criticized. At least it should say: ‘The BFI was calculated from daily streamflow records using the entire streamflow record based on . ’. You may also consider to add this aspect (i.e. the BFI was developed for rainfall regimes) to the discussion. Added to P8, line 13 “The BFI was calculated from the entire daily streamflow records. ” Also added to the discussion (page 21, line 5-11): For the final selection of catchments, the BFI was calculated following the approach of Gustard and Demuth (2009). It should be kept in mind that this approach (which uses turning points in minimum flow of a 5 day moving filter to define base flow) was originally designed for rainfall dominated regimes and might represent base flow differently for some of the snow or glacier melt dominated catchments with long-lasting seasonal melt peaks and recessions that are thus more related to climate than to catchment controls (Gustard and Demuth, 2009). Although out of the scope for this research, a more catchment control-specific representation of base flow could be obtained with other calculation procedures. P10, L10: replace ‘5’ with ‘five’.
Business process reengineering: management's new paradigm or emperor's new clothes?

Business Process Reengineering (BPR) is currently attracting much attention as an approach to organisational change, but has received relatively little critical scrutiny. This paper seeks to examine the origins, antecedents and content of BPR as they are described in the main writings on the topic, in order to address three questions: Is there one form of BPR or many? Is it new? What/actors may account/or its popularity? Some of the criticisms that have been made of BPR are also discussed.
Impact of photooxidation on microbial degradation of dissolved organic carbon in streamwater and shallow groundwater

Die Herkunft, Struktur, Zusammensetzung, die photochemische Veranderung und Bioverfugbarkeit von gelosten Organischen Material (DOM) beeinflussen Fliesgewasserokosysteme und ihre Kohlenstoff Flusse. Das Ziel dieser Studie ist das Verstandnis, wie diese Komponenten chromophores DOM (DDOM) in seinen optischen Eigenschaften und mikrobieller Prozessierung beeinflussen. Die Experimente inkludierten das Monitoring von photochemischen Effekten von Strahlung auf autochthon und allochthon produzierten Kohlenstoff und anschliesenden mikrobiellen Abbauprozessen. Excitation-Emission Spektroskopie und Absorptions- Spektroskopie ermoglichten eine Beschreibung und Qualifikation der Anderung von optischen und fluoreszierenden Eigenschaften. Die mikrobielle Respiration wurde beobachtet um eine Anderung in der Bioverfugbarkeit von bestrahlten Proben des Lunzer Unterseebaches und von verschiedenen anschliesenden Wasserkorpern zu identifizieren. Die Proben wurden einem Spektrum, ahnlich dem des naturlichen Sonnenlichts, ausgesetzt. Dadurch veranderten sich die optischen Eigenschaften signifikant und die Bioverfugbarkeit des DOC fur den mikrobiellen Metabolismus wurde erhoht. Autochthones DOC von periphytischen Algen stammend folgte diesem Muster nicht. Die Resultate indizieren, dass ein groser Anteil an organischem Kohlenstoff, welcher aus dem Auboden stammt, in den Bach eingeschwemmt wurde. Meine Resultate schlagen vor, dass dieser als refraktar betrachtete organische Kohlenstoff einer Photooxidation durch naturliches Sonnenlicht wahrend eines Bach abwarts gerichteten Transportes unterliegt, und so teilweise in Komponenten eines geringeren Molekulargewichtes transformiert wird. Diese veranderten Substrate erhohen den mikrobiellen Metabolismus. Die photochemische Veranderung von CDOM bietet die Moglichkeit einer mikrobiellen Prozessierung der photooxidierten Substrate, wodurch CO2 Emissionen erhoht und die CDOM Konzentrationen reduziert werden.
Tax Compliance as a Coordination Game

This paper uses laboratory experiments to investigate compliance behavior when returns are selected for audit based upon the deviation of each individual’s tax report from the average report of all other taxpayers. Our experimental results indicate that individuals find it difficult to coordinate on the zero-compliance equilibrium. However, pre-game communication that mimics information-sharing provided by tax guides provides a mechanism that allows such coordination. Nevertheless, the tax authority is able to overcome this taxpayer coordination by a subtle change is its audit rule, a change that targets the audits in a different way without increasing the number of audits.
Working Papers Series : Growth and Employment in Europe : Sustainability and Competitiveness Working

In this paper we analyse the influence of sector specific developments in productivity and demand on net entry and employment in 19 industrial sectors of the Austrian economy. Based on the model of structural dynamics of Pasinetti, we develop an identification scheme that allows us to extract technology and demand shocks, by means of a structural vector autoregressive (SVAR) model with long-run restrictions. We study the patterns of productivity and demand shocks across industries by means of a principal components analysis and find that sectoral and macro-economic developments in demand strongly correlate, while this is not the case for technology shocks. Impulse-response analysis shows that for almost all sectors productivity growth rates experience an immediate increase to positive technology shocks while the hours worked decline as conjectured by Pasinetti. Finally, we use the identified shocks as explanatory variables in time-series cross-section regressions on net-entry and employment data. Both types of shocks are able to explain dynamics on the industry level in terms of employment and sales but not firm dynamics.

KINEMATICS AND CHEMISTRY OF HALO SUBSTRUCTURES: THE VICINITY OF THE VIRGO OVERDENSITY

We present observations obtained with the Anglo-Australian Telescope's 2dF wide field spectrograph AAOmega of K-type stars located within a region of the sky which contains the Virgo Overdensity and the leading arm of the Sagittarius Stream. On the basis of the resulting velocity histogram, we isolate halo substructures in these overlapping regions including Sagittarius and previously discovered Virgo groups. Through comparisons with N-body models of the Galaxy–Sagittarius interaction, we find a tri-axial dark matter halo is favored and we exclude a prolate shape. This result is contradictory with other observations along the Sagittarius leading arm, which typically favor prolate models. We have also uncovered K-giant members of Sagittarius that are notably more metal-poor (〈[Fe/H]〉 = −1.7 ± 0.3 dex) than previous studies. This suggests a significantly wider metallicity distribution exists in the Sagittarius Stream than formerly considered. We also present data on five carbon stars which were discovered in our sample.
Detecting a Multi-Homed Device Using Clock Skew

Abstract : The aim of this thesis was to determine the feasibility of identifying a device connected to the Internet through multiple interfaces (i.e., multi-homed) using only the information provided by passively observing network traffic. Since multi-homed hosts allow an alternate means for outside entities to circumvent the security of a firewall and gain access to a network, it is important for a networks security to be able to detect and remove such devices. In this work, the idea of using clock skewwhich is the difference in perceived time between two system clocksas a unique signature is utilized to identify hosts on a network that are potentially multi-homed. Testing was done on a software-defined network that contained a multihomed host. After traffic between hosts was collected and analyzed, analysis of the confidence intervals of the devices clock skew was conducted to determine if IP addresses originating from the same host could be successfully detected solely from network traffic. Testing confirmed that the proposed scheme provided a valid means of detecting a multi-homed device on a network. This scheme was repeated on multiple hosts and on a device with multiple connections to the network.
UNIQUENESS OF A LIMIT CYCLE FOR A PREDATOR-PREY SYSTEM*

The uniqueness of a limit cycle for a predator-prey system is proved in this paper. We assume that in the absence of predation the prey regenerates by logistic growth and the predator feeds on the prey with a saturating functional response to prey density. Specifically, we assume that Michaelis–Menten kinetics describe how feeding rates and birth rates change with increasing prey density.
Suggesting a resilient and systemic oriented psychodynamic model to include students with behavioural problems: Theoretical issues and practical challenges

This paper presents an overview of available research data on the functioning of children with behavioural problems, and also discusses school-based risk and protective factors, and school problems in children with conduct problems. Additionally, emphasis has been placed on the presentation of key features of a psychoeducational counselling and psychodynamic resilient based intervention model which aims to address disruptive and disturbing behaviours within the school setting in partnership with school staff and in a systemic pesrpective. A case vignette is presented in order to better illustrate the basic tenets of this model.
