The Interaction Between the Physical Environment and Metaphysical States: The Role of Social Anxiety and Stress in Informing Spatial Perception

The current study looks at the interaction between social anxiety, stress, and spatial perception. The hypothesis is that under stress, participants will see an anxiety-provoking stimulus as closer and larger and perceive themselves as shorter, particularly if they are higher on the social anxiety scale. Participants either did a variation of the Trier Social Stress Test or were in a control group, and then estimated spatial properties of a social stimulus, a video camera, as well as estimates of their own height. Finally, participants completed self-reported stress measures, the shortened Spielberger State-Trait Anxiety Inventory (STAI) and the shortened Social Interaction Anxiety Scale (SIAS). Results indicated a marginally significant trend for the stress condition perceiving the video camera as smaller and further away, a significant trend for participants with social anxiety seeing the video camera as significantly larger, and certain subsets of social anxiety accounted for seeing the video camera as closer. There was no interaction between stress and anxiety on spatial estimates. Finally, participants who were upset perceived their self-height as shorter than their actual height. Results distinguish the role of stress and social anxiety in driving perception to prepare an individual for action, and implications are discussed in the realm of therapies for social anxiety.

The quenching of star formation in accretion-driven clumpy turbulent tori of active galactic nuclei

Galactic gas-gas collisions involving a turbulent multiphase ISM share common ISM properties: dense extraplanar gas visible in CO, large linewidths (>= 50 km/s), strong mid-infrared H_2 line emission, low star formation activity, and strong radio continuum emission. Gas-gas collisions can occur in the form of ICM ram pressure stripping, galaxy head-on collisions, compression of the intragroup gas and/or galaxy ISM by an intruder galaxy which flies through the galaxy group at a high velocity, or external gas accretion on an existing gas torus in a galactic center. We suggest that the common theme of all these gas-gas interactions is adiabatic compression of the ISM leading to an increase of the turbulent velocity dispersion of the gas. The turbulent gas clouds are then overpressured and star formation is quenched. Within this scenario we developed a model for turbulent clumpy gas disks where the energy to drive turbulence is supplied by external infall or the gain of potential energy by radial gas accretion within the disk. The cloud size is determined by the size of a C-type shock propagating in dense molecular clouds with a low ionization fraction at a given velocity dispersion. We give expressions for the expected volume and area filling factors, mass, density, column density, and velocity dispersion of the clouds. The latter is based on scaling relations of intermittent turbulence whose open parameters are estimated for the CND in the Galactic Center. The properties of the model gas clouds and the external mass accretion rate necessary for the quenching of the star formation rate due to adiabatic compression are consistent with those derived from high-resolution H_2 line observations. Based on these findings, a scenario for the evolution of gas tori in galactic centers is proposed and the implications for star formation in the Galactic Center are discussed.
High-precision measurement of the hypertriton mass

In recent years, the high-precision technique of decay-pion spectroscopy at the Mainz Microtron (MAMI), using high-resolution magnetic spectrometers, contributed to the accurate determination of the $\Lambda$ binding energy of $^4_\Lambda$H. For the lightest hypernucleus, the hypertriton, the binding energy is known only from measurements carried out with nuclear emulsions. An account is given on the potential of observing the hypertriton with decay-pion spectroscopy from fragmentation of light target nuclei. Statistical decay calculations suggest that lithium is the optimal target material to observe hypertriton decays under relative clean conditions with only few other light hyperfragments being produced. Finally, a high-precision measurement of the hypertriton mass at MAMI is proposed.
Determination and Detection of Blind Zones in Vehicles Based on Microcontroller

In this paper, the PIC microcontroller (16F877A) based on ultrasonic (PING) sensor is developed to determine and detect the blind zones in vehicles in addition it measures the distance of targets approaching a vehicle for avoiding lateral collisions and providing a safe driving. The temperature sensor (LM35) circuit has been added to proposal hardware circuit to improve the precision in case of changing weather temperature in different seasons. One of the benefits of this system is its ability to detect and alert the driver when a vehicle is in danger of collision, thus increasing the safety of not only the driver, but of the vehicle itself. The proposal system has low-cost, the implementation of convenient, easy touse, flexible.The ranging values are real-time displayed in high precision and stable performance through the Liquid Crystal Display (LCD) which update for each second. The software design of the proposal system is carried out by Proton IDE Basic program. This program is high-level language which is employed to program microcontroller.
Deterministic and Stochastic Models of NF j B Pathway

In the article, we discuss the state of art and perspectives in deterministic and stochastic models of NFjB regulatory module. The NFjB is a transcription factor controlling various immune responses including inflammation and apoptosis. It is tightly regulated by at least two negative feedback loops involving IjBa and A20. This mode of regulation results in nucleus-to-cytoplasm oscillations in NFjB localization, which induce subsequent waves of NFjB responsive genes. Single cell experiments carried by several groups provided comprehensive evidence that stochastic effects play an important role in NFjB regulation. From modeling point of view, living cells might be considered noisy or stochastic biochemical reactors. In eukaryotic cells, in which the number of protein or mRNA molecules is relatively large, stochastic effects primarily originate in regulation of gene activity. Transcriptional activity of a gene can be initiated by transactivator molecules binding to the specific regulatory site(s) in the target gene. The stochastic event of gene activation is amplified by transcription and translation, since it results in a burst of mRNA molecules, and each copy of mRNA then serves as a template for numerous protein molecules. Another potential source of variability can be receptors activation. At low-dose stimulation, important in cell-to-cell signaling, the number of active receptors can be low enough to introduce substantial noise to downstream signaling. Stochastic modeling confirms the large variability in cell responses and shows that no cell behaves like an ‘‘average’’ cell. This high cell-to-cell variability can be one of the weapons of the immune defense. Such non-deterministic defense may be harder to overcome by relatively simple programs coded in viruses and other pathogens.
Recovery of Ketamine from Ribena using Liquid-Liquid Extraction Followed by Gas Chromatography Techniques

Raves and night clubs are always associated with recreational drugs, which are also referred as ‘club drugs’. Dissolving illegal drugs, such as ketamine, into liquid forms to be disguised as bottled soft drinks is one of the current drug concealment methods. This study is aimed to develop a method for detection and quantitation of ketamine contained in soft drink. Recovery efficiency, in term of precision and accuracy, of liquid-liquid extraction (LLE) method used to extract ketamine from the soft drink ‘Ribena’ was carried out. Gas Chromatography–Mass Spectrometry (GC-MS) analysis was used to confirm the presence of ketamine in the extracts, followed by Gas Chromatography–Flame Ionisation Detector (GC-FID) analysis to quantify the amount of ketamine. Repeated extraction on same sample produced consistent recovery results (RSD = 6.77%). In spiked samples, the average recovery percentage of ketamine was found to be 87.27 ± 5.72 %. In conclusion, the analytical procedures of LLE, coupled with GC-MS and GC-FID in recovery study were found to be useful to extract, detect and quantify ketamine in drug-laced soft drink.
Quantum Systems in Chemistry and Physics

In this paper we present the ®rst application of the ZORA (Zeroth Order Regular Approximation of the Dirac Fock equation) formalism in Ab Initio electronic structure calculations. The ZORA method, which has been tested previously in the context of Density Functional Theory, has been implemented in the GAMESS-UK package. As was shown earlier we can split off a scalar part from the two component ZORA Hamiltonian. In the present work only the one component part is considered. We introduce a separate internal basis to represent the extra matrix elements, needed for the ZORA corrections. This leads to different options for the computation of the Coulomb matrix in this internal basis. The performance of this Hamiltonian and the effect of the different Coulomb matrix alternatives is tested in calculations on the radon en xenon atoms and the AuH molecule. In the atomic cases we compare with numerical Dirac Fock and numerical ZORA methods and with non relativistic and full Dirac basis set calculations. It is shown that ZORA recovers the bulk of the relativistic effect and that ZORA and Dirac Fock perform equally well in medium size basis set calculations. For AuH we have calculated the equilibrium bond length with the non relativistic Hartree Fock and ZORA methods and compare with the Dirac Fock result and the experimental value. Again the ZORA and Dirac Fock errors are of the same order of magnitude.
Precise Orbit Determination of the GOCE Re-Entry Phase

During the last days of the GOCE mission, after the GOCE spacecraft ran out of fuel, it slowly decayed before finally re-entering the atmosphere on the 11th November 2013. As an integrated part of the AOCS, GOCE carried a GPS receiver that was in operations during the re-entry phase. This feature provided a unique opportunity for Precise Orbit Determination (POD) analysis. As part of the activities carried out by the Navigation Support Office (HSO-GN) at ESOC, precise ephemerides of the GOCE satellite have been reconstructed for the entire re-entry phase based on the available GPS observations of the onboard LAGRANGE receiver. All the data available from the moment the thruster was switched off on the 21st of October 2013 to the last available telemetry downlink on the 10th November 2013 have been processed, for a total of 21 daily arcs. For this period a dedicated processing sequence has been defined and implemented within the ESA/ESOC NAvigation Package for Earth Observation Satellites (NAPEOS) software. The computed results show a post-fit RMS of the GPS undifferenced carrier phase residuals (ionospheric-free linear combination) between 6 and 14 mm for the first 16 days which then progressively increases up to about 80 mm for the last available days. An orbit comparison with the Precise Science Orbits (PSO) generated at the Astronomical Institute of the University of Bern (AIUB, Bern, Switzerland) shows an average difference around 9 cm for the first 8 daily arcs and progressively increasing up to 17 cm for the following days. During this reentry phase (21st of October 10th November 2013) a substantial drop in the GOCE altitude is observed, starting from about 230 km to 130 km where the last GPS measurements were taken. During this orbital decay an increment of a factor of 100 in the aerodynamic acceleration profile is observed. In order to limit the mis-modelling of the non-gravitational forces (radiation pressure and aerodynamic effects) the newly developed software ARPA (Aerodynamics and Radiation Pressure Analysis) has been adopted to compute the forces acting on GOCE. An overview of the software techniques and the results of its implementation is presented in this paper. The use of the ARPA modelling leads to an average reduction of the carrier phase post-fit RMS of about 2 mm and decrement of the difference with the PSO orbits of more than 1 cm.
Taxonomy and palaeoecology of Cenomanian-Turonian ( Upper Cretaceous ) echinoids from eastern Sinai , Egypt

The Cenomanian-Turonian rocks of Gebel Areif El-Naqa and Wadi Quseib (eastern Sinai) yield associations of echinoids and other macrobenthic faunal elements (e.g. oysters, gastropods, corals). Twenty-six echinoid species (thirteen regular and thirteen irregular) belonging to sixteen genera, fourteen families, and eight orders are identified, systematically described, and their stratigraphic and palaeogeographic distribution is discussed. Based on a functional morphological analysis, the mode of life and feeding of the different taxa is reconstructed. Two main types of facies have been recognized in the studied sections: marl and reefal carbonates. The marly facies is dominated by burrowing and ploughing irregular echinoids, whereas the reefal carbonates are dominated by grazing epifaunal regular echinoids. Some of the echinoid tests (e.g. Heterodiadema libycum) together with oyster shells have been affected by bioerosion and encrustation. Egypt, Sinai, Cenomanian-Turonian, lithostratigraphy, echinoids, taxonomy, palaeoecology, taphonomy Zusammenfassung: Die Gesteine des Gebel Areif El-Naqa und Wadi Quseib (östliche Halbinsel Sinai) enthalten Gemeinschaften von Echinoideen und anderen Faunenelementen des Makrobenthos (z. B. Austern, Gastropoden oder Korallen). 26 Seeigel-Arten (13 „reguläre“ und 13 „irreguläre“) werden taxonomisch beschrieben und ihre stratigraphische und paläogeographische Verbreitung diskutiert. Sie gehören 16 Gattungen, 14 Familien und 8 Ordnungen an. Die Lebensund Ernährungsweise der verschiedenen Taxa wird anhand funtionsmorpholgischer Analysen rekonstruiert. Zwei Haupt-Faziestypen lassen sich in den untersuchten Profilen unterscheiden: Mergel und Riff(nahe)-Karbonate. Die Mergelfazies wird von infaunalen und semi-infaunalen „irregulären“ Echinoideen dominiert, während die Riff(nahe)-Karbonatfazies von epifaunalen „regulären“ Seeigeln dominiert wird.

Valuing the Impact of Climate Change Policies on Forestry

Conventional forest valuation approaches do not account for discretions foresters have in making key irreversible decisions such as when and if to harvest in the light of uncertain future decision variables. Furthermore where they are sufficiently sophisticated as to make explicit forecasts of future valuation parameters such as log prices at harvest date as is the case for discounted cash flow (DCF) analysis they do so with unavoidable imprecision. These shortcomings - as well of those of even less sophisticated methodologies such as cost- or transaction-based valuations - become telling when attempting to assess the impacts of long-term climate change policies on forest values. This paper presents an alternative approach using real options analysis that captures enough complexity to meaningfully model the impacts of climate change policies on forest value while remaining relatively straightforward to implement using Monte Carlo simulation. It shows that foresters' discretions as to when and if to harvest or to convert to non-forest land uses give rise to real options whose value is captured by real options analysis but ignored by conventional forest valuation methodologies. It furthermore shows how forest values differ and conversion rates vary over time depending on which climate change policies or policy uncertainties are assumed. In short Kyoto forests (those first planted after 1989) are more valuable when carbon credits and harvest liabilities under the Kyoto Protocol are devolved by the Crown to their owners. Non-Kyoto forests (those planted before 1990) are more valuable when deforestation liabilities are not devolved to their owners. Current New Zealand policy under which deforestation liabilities are retained by the Crown only within limits encourages the early conversion of Non-Kyoto forests into non-forest uses.
Evaluation and strategies of tolerance to water stress in Paspalum germplasm

The evaluation of genetic resources in germplasm banks of Paspalum can contribute to their use in breeding programs and for advanced research in biotechnology. This study evaluated the tolerance of 11 Paspalum accessions to abiotic stress caused by soil water deficit in a greenhouse experiment at Embrapa Pecuaria Sudeste, Sao Carlos, state of Sao Paulo, Brazil. The variables analyzed were: dry biomass of green matter, dead matter and roots; leaf area; leaf water potential; number of days to lose leaf turgor (wilting); soil moisture at wilting; and number of tillers per pot. The results showed high genetic variability for all traits, not only among species but also within species, and also reflected the existence of different strategies of response and potential adaptation to water deficit events. For breeding programs, when the aim is to produce materials better adapted to the occurrence of prolonged drought, 5 accessions from this group seem to have good potential: P. malacophyllum BGP 289, P. quarinii BGP 229, P. regnellii BGP 112, P. conspersum BGP 402 and P. urvillei x P. dilatatum BGP 238. Conversely, when the goal is to select materials for short-term water stress conditions, 6 accessions stand out: P. atratum BGP 308, P. regnellii BGP 215, 248 and 397, P. dilatatum BGP 234 and P. malacophyllum BGP 293.

Separation and Quantification of Hydrocarbons of LPG Using Novel MWCNT-Silica Gel Nanocomposite as Packed Column Adsorbent of Gas Chromatography

In this study, a new silica gel based adsorbent was fabricated and its ability in separation and quantification of alkanes mixture was investigated. Silica gel (SiO2) is a polar absorbent which is mainly used to separate polar compounds. Also, the carbon materials such as activated carbon and recently carbon nanotube (CNTs), have been widely used for separation of nonpolar materials. Carbon nanotubes are nanosized carbon-based sorbents that have a high surface area and a large aspect ratio and are known to be stable at high temperatures. It is, therefore, conceivable to use of their unique properties in gas chromatography. In this work, a MWCNT-Silica gel nanocomposite was prepared by Sol-Gel process and it was used as stationary phase in gas chromatography for separation of alkanes mixture. In first part, ability of silica gel adsorbent was studied and then results were compared with new MWCNT-Silica gel nanocomposite. Finally, a quantitative investigation was done on a LPG sample and propane, 2-methylpropane, n-butane, 2,2-dimethylpropane, 2-methylbutane and n-pentane were measured by standard addition.
Suggestions for the next wave of BPM research : strengthening the theoretical core and exploring the protective belt

In this essay, I present a reflective and generative analysis of Business Process Management research, in which I analyze process management and the surrounding research program from the viewpoint of a theoretical paradigm embracing analytical, empirical, explanatory and design elements. I argue that this view not only reconciles different perceptions of BPM and different research streams, but that it also informs ways in which the BPM research program could develop into a much richer, more inclusive and overall more significant body of work than it has to date. I define three perspectives on a BPM research agenda, give several examples of exciting existing research, and offer key opportunities for further research that can (a) strengthen the core of BPM, (b) generate novel theory from BPM in relevant and topical big issue domains, and (c) explore more rigorously and comprehensively the protective belt of BPM assumptions that much of the present research abides by. The essay ends with some recommendations for continuing the debate about what constitutes BPM and some suggestions for how future research in this area might be carried out.
Internal marketing and organisational performance of SMEs in the EDV industrial sector

Abstract Focusing on the industrial sector, this research aims to identify conditions for the implementation of internal marketing concepts among employees and its impact on the organisational performance. Only one study was found simultaneously integrating the two constructs. It concerned the cork processing industry alone, yet considered expanding the efforts – namely, using qualitative exploratory research in the form of 10 in-depth interviews based on a script of generally open questions – to the entire industry in the Portuguese region between rivers Douro and Vouga. The unit of analysis was constructed considering distinct features as well as activity criteria and the geographic location, thus ensuring the necessary heterogeneity. The results inform about the awareness of the internal marketing conceptualisation. The research found that all analysed enterprises had more or less structured model frames and worked with the conceptualisation of the guidance for the internal market, a strategic concern, and in some instances, this concept was an organisational desideratum in the sector. In addition to the lapse of the research according to a qualitative paradigm of exploratory nature, the main limitation is the need for objective sustainably of the results obtained through future quantitative studies to promote an integrated triangulation of their outcomes. The research allowed identifying the companies that use organisational models conducive to the individual well-being of employees and facilitating the desired orientation to the market.
