description: Quaternary paleoecological data is still relatively scarce for southwestern Alberta. Accordingly, the objective of this research is to provide information on the post-glacial paleoenvironmental history of the Morley Flats and Kananaskis Valley region of southwestern Alberta. In pursuit of this goal, a radiometrically and tephrachronologically dated core from a small bog near the Yamnuska Centre on the Morley Flats and a radiometrically and tephrachronologically dated lacustrine sediment section from Wedge Lake in the Kananaskis Valley are examined in terms of several paleoecological parameters. Sediment grain size distribution and carbonate content are assessed to provide details of the depositional history for each study site. Palynological analysis is utilized to reconstruct the vegetational history of the region. Fossil molluscan faunal analysis is employed to provide data on environmental variation in the aquatic environment of each study site. In addition, a number of descriptive, preliminary, bivariate and multi-variate statistical techniques are examined in terms of their applicability to the paleoecological data. The empirical interpretation of the results of this research provides a detailed assessment of the post-glacial paleoenvironmental history of the study site. Immediately following deglaciation of the Morley Flats, a tundra-like vegetation was able to colonize the cold and dry region. By at least 10,400 110 B.P. (GSC-2965) the major portion of the Kananaskis Valley, including Wedge Lake, was ice-free and coniferous forests were establishing themselves in the area. A significant trend of climatic amelioration continued from this period until shortly after the deposition of a pyroclastic layer which is tentatively identified as Mazama Tephra. This period of warm and dry conditions was interrupted once by an episode of climatic deterioration which occurred after 9395 + 215 B.P. (GX-6767) and prior to 6600 B.P. Following the deposition of the tephra layer, conditions deteriorated significantly. This episode was followed by a period of renewed climatic amelioration. By 1140 + 70 B.P. (Beta-1282) cool and moist conditions again became prevalent.

description: We report observation of the enhancement of superconductivity near lattice dislocations and the absence of the strengthening of vortex pinning in odd-parity superconductor Sr$_2$RuO$_4$, both surprising results in direct contrast to the well known sensitivity of superconductivity in Sr$_2$RuO$_4$ to disorder. The enhanced superconductivity appears to be related fundamentally to the two-component nature of the superconducting order parameter, as revealed in our phenomenological theory taking into account the effect of symmetry reduction near a dislocation.

title: The role of AP-1 transcription factor expression in androgen sensitive and androgen independent prostate cancer
Creators: name: Nalagatla, Sarath Krishna

Subjects: subject: Oncology.

description: Development of androgen independent prostate cancer (AIPC) carries a poor prognosis. The underlying molecular mechanisms are complex and not completely understood. Androgen receptor dependent and independent mechanisms have been postulated. AP-1 is a transcription factor whose components are nuclear proteins encoded by c-Jun and c-Fos proto-oncogenes. The possible role of c-Jun and c-Fos in contributing to the development of androgen independent prostate cancer in-vivo using paired human prostate cancer tissue samples has not been studied before. Study hypothesis- AP-1 transcription factor related proteins are dysregulated in the emergence of androgen independent prostate cancer. Aims of the study- 1. To establish a paired clinical cohort of patients in which prostate cancer tissue is available at diagnosis of prostate cancer and also following the development of androgen independence in order to test the hypothesis by immunohistochemistry. 2. To evaluate the expression of AP-1 related proteins in androgen sensitive and androgen independent prostate cancer, by immunohistochemistry. We demonstrated that both androgen sensitive and androgen independent prostate cancers express c-Jun, c-Fos, phosphorylated c-Jun, PKC, COX-2 and AR proteins. A significant proportion of tumours expressed high levels of AP-1 at relapse (c-Jun 68.6%, 35/51; P-Jun, 47%, 24/51; c-Fos 40%, 20/51). An increase or no change in AP-1 (c-Jun, P-Jun & c-Fos) was observed in >80% of AlPCs. Also an increase or no change in PKC (55%), COX-2(70%) and AR (90%) protein expression in AlPC was observed. Differences in the levels of protein expression were observed as androgen sensitive prostate tumours progressed to androgen independent state. In androgen sensitive prostate tumours, we demonstrated a statistically significant correlation in expression of c-Jun, c-Fos and p-Jun proteins (table 14). In androgen independent prostate tumours c-Jun expression correlated with phosphorylated c-Jun with statistical significance (p=<0.0001). We also demonstrated that, high levels of phosphorylated c-Jun and an increase in Protein Kinase C expression at relapse were associated with a decrease in the duration of survival from relapse (p=0.003). Protein Kinase C expression correlated with COX-2 expression in both androgen sensitive as well as in androgen independent prostate tumours (p=0.014 & 0.002 respectively). Also AR protein expression correlated with phosphorylated c-Jun expression in both ASPC and AlPC (p=0.003 & 0.07 respectively). This confirms that both the proteins are involved in the progression of ASPC to AlPC as demonstrated in cell line studies [110, 204]. The study has demonstrated that AP-1 related proteins are dysregulated with the emergence of androgen independent prostate cancer in a subset of patients thus proving the hypothesis.

description: In this paper we study a model of synchronization process on scale free networks with degree-degree correlations. This model was already studied on this kind of networks without correlations by Pastore y Piontti {\it et al.}, Phys. Rev. E {\bf 76}, 046117 (2007). Here, we study the effects of the degree-degree correlation on the behavior of the load fluctuations $W_s$ in the steady state. We found that for assortative networks there exist a specific correlation where the system is optimal synchronized. In addition, we found that close to this optimally value the fluctuations does not depend on the system size and therefore the system becomes fully scalable. This result could be very important for some technological applications. On the other hand, far from the optimal correlation, $W_s$ scales logarithmically with the system size.

description: A recently developed computational methodology for executing numerical calculations with infinities and infinitesimals is described in this paper. The developed approach has a pronounced applied character and is based on the principle `The part is less than the whole' introduced by Ancient Greeks. This principle is used with respect to all numbers (finite, infinite, and infinitesimal) and to all sets and processes (finite and infinite). The point of view on infinities and infinitesimals (and in general, on Mathematics) presented in this paper uses strongly physical ideas emphasizing interrelations holding between a mathematical object under the observation and tools used for this observation. It is shown how a new numeral system allowing one to express different infinite and infinitesimal quantities in a unique framework can be used for theoretical and computational purposes. Numerous examples dealing with infinite sets, divergent series, limits, and probability theory are given.

description: We calculate the evolution of fluorine in the solar neighborhood with the ν-process of core-collapse supernovae, the results of which are in good agreement with the observations of field stars. The ν-process operating in supernovae causes the [F/O] ratio to plateau at [O/H] < -1.2, followed by a rapid increase toward [O/H] ~ -0.5 from the contribution of Asymptotic Giant Branch stars. The plateau value of [F/O] depends on the neutrino luminosity released by core-collapse supernovae and may be constrained by using future observations of field stars at low metallicities. For globular clusters, the handful of [F/O] measurements suggest that the relative contribution from low-mass supernovae is smaller in these systems than in the field.

description: The Ciletuh-Palabuhanratu UNESCO Global Geopark (CPUGG) is one of the National Strategic Tourism Areas in Indonesia. As a tourist destination, the coast in CPUGG is feared to experience ecosystem pressure due to the increase in visitor numbers and physical development to support tourism facilities and infrastructure. This study aims to assess the impact of tourism activities on the landscape and ecosystem in the coastal area of CPUGG. Information about the impact risk value is needed as a preliminary step to identify the tourism activities that most significantly affect the landscape and ecosystem. Moreover, by applying impact risk assessments to several tourist beaches in CPUGG, it is hoped to identify which beaches have landscapes and ecosystems in concerning conditions. Data from the impact risk analysis is needed as input in managing ecosystem-based management, which is part of the implementation of sustainable tourism development. Data for this research were collected through interview techniques as well as direct observations and measurements in the field. Initial observation results identified seven human activities that pose a risk of causing environmental pressure in CPUGG.

description: This paper proposes a nonparametric test of Granger causality in quantile. Zheng (1998, Econometric Theory 14, 123–138) studied the idea to reduce the problem of testing a quantile restriction to a problem of testing a particular type of mean restriction in independent data. We extend Zheng’s approach to the case of dependent data, particularly to the test of Granger causality in quantile. Combining the results of Zheng (1998) and Fan and Li (1999, Journal of Nonparametric Statistics 10, 245–271), we establish the asymptotic normal distribution of the test statistic under a β-mixing process. The test is consistent against all fixed alternatives and detects local alternatives approaching the null at proper rates. Simulations are carried out to illustrate the behavior of the test under the null and also the power of the test under plausible alternatives. An economic application considers the causal relations between the crude oil price, the USD/GBP exchange rate, and the gold price in the gold market.

description: Plagiarism is a widespread problem in computer science education. Manual inspection is impractical for large courses, and the risk of detection is thus low. Many plagiarism detectors are available for programming assignments. However, very few approaches are available for modeling assignments. To remedy this, we introduce token-based plagiarism detection for metamodels. To this end, we extend the widely-used software plagiarism detector JPlag. We evaluate our approach with real-world modeling assignments and generated plagiarisms based on obfuscation attack classes. The results show that our approach outperforms the state-of-the-art.

description: The main goal of this paper is to give a rigorous mathematical description of systems for processing quantum information. To do it authors consider abstract state machines as models of classical computational systems. This class of machines is refined by introducing constrains on a state structure, namely, it is assumed that state of computational process has two components: a control unit state and a memory state. Then authors modify the class of models by substituting the deterministic evolutionary mechanism for a stochastic evolutionary mechanism. This approach can be generalized to the quantum case: one can replace transformations of a classical memory with quantum operations on a quantum memory. Hence the authors come to the need to construct a mathematical model of an operation on the quantum memory. It leads them to the notion of an abstract quantum automaton. Further the authors demonstrate that a quantum teleportation process is described as evolutionary process for some abstract quantum automaton.

description: Using infrared and X-ray diagnostics, we study star--formation and black hole accretion in nearby and distant galaxies.  We examine diagnostics of the hardness of the ionizing field in low--redshift starburst galaxies,

to constrain the initial mass function.  We obtain new measurements of He I 1.7 micron to Br 10, a

physically simple diagnostic, then test ISO mid--infrared line ratios, finding them reliable.  Compared to new photoionization models, the ISO ratios in 27 nearby starburst galaxies are systematically low. This argues that solar--metallicity starbursts are deficient in massive stars, or that such stars are present but highly embedded.

Using Spitzer, HST, Chandra, and ground-based data, we examine the multi-wavelength (0.4--24 micron) spectral energy distributions and X-ray properties of X-ray--selected active galactic nuclei (AGN) in several deep fields: the Chandra Deep Field South, the Lockman Hole, and the extended Groth Strip.

We examine the 24 micron to X-ray flux and luminosity ratios for 157 AGN at z~1; the luminosity ratios have not strongly evolved since $z\sim0$, and we find no trend with X-ray column density.   This means that highly--obscured AGN do not have exceptional infrared fluxes.  We examine the SEDs of 45 bright X-ray and 24 micron sources: only $22\%$ are classified as unobscured ``type 1'' AGN; 18% are classified as ULIRG-like SEDs; and the majority are classified as obscured (``type 2'') AGN or spiral--like SEDs.  This supports the picture from X-ray surveys that much of the AGN activity in the distant universe is significantly obscured.

We examine why 20% of X-ray--selected AGN are optically--faint; they lie at significantly higher redshifts (median z=1.6) than most X-ray--selected AGN, and their spectra are intrinsically red.  Their contribution to the X-ray Seyfert luminosity function is comparable to that of optically--bright AGN at z>1, but they do not significantly alter the redshift distribution.

Lastly, we investigate why half of X-ray--selected AGN lack signs of accretion in optical spectra.  We find that these ``optically--dull'' AGN have Seyfert--like mid--infrared emission, which argues that they do not have abnormally--weak UV/optical continua.  The axis ratios of their host galaxies argue that extinction by host galaxies plays a key role in hiding nuclear emission lines.

description: The fluctuating and dissipative dynamics of matter-wave dark solitons within harmonically trapped, partially condensed Bose gases is studied both numerically and analytically. A study of the stochastic Gross-Pitaevskii equation, which correctly accounts for density and phase fluctuations at finite temperatures, reveals dark soliton decay times to be lognormally distributed at each temperature, thereby characterizing the previously predicted long lived soliton trajectories within each ensemble of numerical realizations (S.P. Cockburn {\it et al.}, Phys. Rev. Lett. 104, 174101 (2010)). Expectation values for the average soliton lifetimes extracted from these distributions are found to agree well with both numerical and analytic predictions based upon the dissipative Gross-Pitaevskii model (with the same {\it ab initio} damping). Probing the regime for which $0.8 k_{B}T < μ< 1.6 k_{B}T$, we find average soliton lifetimes to scale with temperature as $τ\sim T^{-4}$, in agreement with predictions previously made for the low-temperature regime $k_{B}T\llμ$. The model is also shown to capture the experimentally-relevant decrease in the visibility of an oscillating soliton due to the presence of background fluctuations.

This parameter is derived from a microscopic description of the decay process. In this way we explain the systematics of proton emission half-lives. At the same time the formation probability is shown to be a useful quantity to determine the deformation property of the mother nucleus.

description: A new paradigm for active galactic jet kinematics has emerged through detailed investigations of BL Lac objects using very long baseline radio interferometry. In this new scheme, most, if not all, jet components appear to remain stationary with respect to the core but show significant non-radial motions. This paper presents results from our kinematic investigation of the jets of a statistically complete sample of radio-loud flat-spectrum active galaxies, focusing on the comparison between the jet kinematic properties of BL Lacs and flat-spectrum radio-quasars. It is shown that there is a statistically significant difference between the kinematics of the two AGN classes, with BL Lacs showing more bent jets, that are wider and show slower movement along the jet axis, compared to flat-spectrum radio-quasars. This is interpreted as evidence for helically structured jets.

Using The Velocity Anisotropy Technique To Investigate Interstellar Magnetohydrodynamic Turbulence

description: Magnetohydrodynamic (MHD) turbulence in the interstellar medium (ISM) influences star formation and subsequently the way our Galaxy evolves. Direct observations of magnetic fields for studying MHD turbulence can be difficult and costly to obtain; as an alternative, we explore a technique called velocity anisotropy to probe MHD turbulence. We apply the velocity anisotropy technique (VAT) in CO radiative transfer MHD simulations for the first time and also to non-synthetic observations for the first time. We find that for optically thin radiative transfer simulations, the sub-Alfvénic and super-Alfvénic regimes are indistinguishable. For the optically thick case the regimes were distinguishable. We then apply the VAT to 12CO and 13CO emission line observations of the Taurus Molecular Cloud, and compare results with that of a principal component analysis (PCA) technique detailed in Heyer & Brunt (2011). We find that increased velocity anisotropy did not correspond to regions of lower gas column density/visual extinction as it did when analyzed with PCA, though this may be due to the selection of region size. We also found 12CO emission to show more velocity anisotropy than 13CO emission, in agreement with the PCA analysis. As a preface to and to supply context for the VAT and its usefulness, we first overview the ISM, turbulence, MHD turbulence in the ISM, and the interstellar magnetic field. We discuss the challenges of observing magnetic fields and the need for methods like VAT to study these fields, MHD turbulence, and the way our Galaxy evolves.

description: The purpose of this thesis is to develop and substantiate the arguments to show that List was not a protectionist, as he is commonly viewed, but rather a proponent of free trade. However, his advocacy of free trade was conditional on the stage of development of the nation concerned. List contrasted Smith's cosmopolitan economy with his own national economy by interposing the "nation" between the individual and the cosmopolitan economy, and distinguished between Smith's theory of exchange value and his own theory of productive power. These powers to create value are more important than value itself. These concepts, which are the distinguishing characteristics of his system, are incorporated into his stage theory to show that different policies are required in different stages of economic development. In terms of his own problem orientation, this meant an advocacy of protective tariffs for the Germany of his time to be able to develop and compete with Britain. Once economic development has reached the agricultural manufacturing- trading stage, free trade was the most conclusive economic policy.
Collapse of massive magnetized dense cores using radiation-magneto-hydrodynamics: early fragmentation inhibition

description: We report the results of radiation-magneto-hydrodynamics calculations in the context of high mass star formation, using for the first time a self-consistent model for photon emission (i.e. via thermal emission and in radiative shocks) and with the high resolution necessary to resolve properly magnetic braking effects and radiative shocks on scales <100 AU. We investigate the combined effects of magnetic field, turbulence, and radiative transfer on the early phases of the collapse and the fragmentation of massive dense cores. We identify a new mechanism that inhibits initial fragmentation of massive dense cores, where magnetic field and radiative transfer interplay. We show that this interplay becomes stronger as the magnetic field strength increases. Magnetic braking is transporting angular momentum outwards and is lowering the rotational support and is thus increasing the infall velocity. This enhances the radiative feedback owing to the accretion shock on the first core. We speculate that highly magnetized massive dense cores are good candidates for isolated massive star formation, while moderately magnetized massive dense cores are more appropriate to form OB associations or small star clusters.

description: Variable-range hopping transport along short one-dimensional wires and across the shortest dimension of thin three-dimensional films and narrow two-dimensional ribbons is studied theoretically. Geometric and transport characteristics of the hopping resistor network are shown to depend on temperature T and the dimensionality of the system. In two and three dimensions the usual Mott law applies at high T where the correlation length of the network is smaller than the sample thickness. As T decreases, the network breaks into sparse filamentary paths, while the Mott law changes to a different T-dependence, which is derived using the percolation theory methods. In one dimension, deviations from the Mott law are known to exist at all temperatures because of rare fluctuations. The evolution of such fluctuations from highly-resistive "breaks" at high T to highly-conducting "shorts" at low T is elucidated.

description: We explore a ballistic orbit model to infer the gravitational drag force on an accreting point mass M, such as a black hole, moving at a hypersonic velocity v_{0} through a gaseous environment of density ρ_{0}. The streamlines blend in the flow past the body and transfer momentum to it. The total drag force acting on the body, including the nonlinear contribution of those streamlines with small impact parameter that bend significantly and pass through a shock, can be calculated by imposing conservation of momentum. In this fully analytic approach, the ambiguity in the definition of the lower cut-off distance $r_{\rm min}$ in calculations of the effect of dynamical friction is removed. It turns out that $r_{\rm min}=\sqrt{e}GM/2v_{0}^{2}$. Using spherical surfaces of control of different sizes, we carry out a successful comparison between the predicted drag force and the one obtained from a high resolution, axisymmetric, isothermal flow simulation. We demonstrate that ballistic models are reasonably successful in accounting for both the accretion rate and the gravitational drag.

description: M87 is the first detected non-blazar extragalactic Tera-Electron-Volt (TeV) source with rapid variation and very flat spectrum in the TeV band. To explain the two-peaks in the spectral energy distribution (SED) of the nucleus of M87 which is similar to those of blazars, the most commonly adopted models are the synchrotron self-Compton scattering (SSC) models and the external inverse Compton scattering (EIC) models. Considering that there is no correlated variation in the soft band (from radio to X-ray) matching the TeV variation, and the TeV sources should not suffer from the gamma-gamma absorption due to the flat TeV spectrum, the EIC models are advantageous in modeling the TeV emission from M87. In this paper, we propose a self-consistent EIC model to explain the flat TeV spectrum of M87 within the framework of fully general relativity, where the background soft photons are from the advection-dominated accretion flow (ADAF) around the central black hole, and the high energy electrons are from the mini-jets which are powered by the magnetic reconnection in the main jet (Giannios et al. 2010). In our model, both the TeV flares observed in the years of 2005 and 2008 could be well explained: the gamma-gamma absorption for TeV photons is very low, even inside the region very close to the black hole 20Rg~50Rg; at the same region, the average EIC cooling time (~ 10^2-10^3s) is short, which is consistent with the observed time scale of TeV variation. Furthermore, we also discuss the possibility that the accompanying X-ray flare in 2008 is due to the direct synchrotron radiation of the mini-jets.

description: Scalar QED is studied with higher order derivatives for the scalar field kinetic energy. A local potential is generated for the gauge field due to the covariant derivatives and the vacuum with non-vanishing expectation value for the scalar field and the vector potential is constructed in the leading order saddle point expansion. This vacuum breaks the global gauge and Lorentz symmetry spontaneously. The unitarity of time evolution is assured in the physical, positive norm subspace and the linearized equations of motion are calculated. Goldstone theorem always keeps the radiation field massless. A particular model is constructed where the the full set of standard Maxwell equations is recovered on the tree level thereby relegating the effects of broken Lorentz symmetry to the level of radiative corrections.

description: The aim of this study was to investigate the chemical composition and antifungal activity of four commercial essential oils from the Burseraceae family - two Boswellia carterii Flueck oils, Canarium luzonicum (Blume) A. Gray oil, and Commiphora myrrha (Nees) Engl oil, against most common Candida spp. recovered from the human oral cavity. The essential oil samples were analyzed by GC-FID and GC/MS. The analysis showed that major essential oils' components were α-pinene (23.04 % and 31.84 %), limonene (45.62 %) and curzerene (34.65 %), respectively. Minimum inhibitory (MIC) and minimum fungicidal (MFC) concentrations were determined using a microdilution standardized technique. All tested Candida spp. clinical isolates and ATCC strains showed susceptibility to tested essential oils in a dose dependent manner. The strongest antifungal activity was shown by essential oil of B. carterii, sample 2; the average MIC values ranged from 1.25 to 1.34 mg/ml, and MFC values ranged from 2.50 to 3.75 mg/ml, depending on the fungus. This study supports the possible use of essential oils from the Bursecaceae family in reduction and elimination of Candida spp. populations in patients with oral cavity fungal infections.

description: Node misbehavior due to selfish or malicious behavior could significantly degrade the performance of MANET because most existing routing protocols in MANET aim to find the most efficient path. Overhearing and reputation based cooperation schemes have been used to detect and isolate the misbehaving nodes as well as to force them to cooperate. Performance analysis has been done for the network traffic using OCEAN over DSR on ns2 while considering the low energy levels for mobile nodes. Throughput, energy level, routing packets and normalized routing overhead are analyzed for OCEAN and normal DSR to show the impact of OCEAN on the overall network performance.

Rapid Disappearance of Penumbra-Like Features Near a Flaring Polarity Inversion Line: The Hinode Observations

description: We present the observations of penumbra like features (PLFs) near a polarity inversion line (PIL) of flaring region. The PIL is located at the moat boundary of active region (NOAA 10960). The PLFs appear similar to sunspot penumbrae in morphology but occupy small area, about 6$\times10^{7}$ km$^{2}$, and are not associated with sunspot or pore. We observed a rapid disappearance of the PLFs after a C1.7 class flare, which occurred close to the PIL. The local correlation tracking (LCT) of these features shows presence of horizontal flows directed away from the end-points of the PLFs, similar to the radial outward flow found around regular sunspots, which is also known as the moat flow. Hard X-ray emission, coincident with the location of the PLFs, is found in RHESSI observations, suggesting a spatial correlation between the occurrence of the flare and decay of the PLFs. Vector magnetic field derived from the observations obtained by Hinode spectro-polarimeter SOT/SP instrument, before and after the flare, shows a significant change in the horizontal as well as the vertical component of the field, after the flare. The weakening of both the components of the magnetic field in the flare interval suggests that rapid cancellation and/or submergence of the magnetic field in PLFs occurred during the flare interval.

description: A general and exact critical condition of saddle-node bifurcation is derived in closed form for the buck converter. The critical condition is helpful for the converter designers to predict or prevent some jump instabilities or coexistence of multiple solutions associated with the saddle-node bifurcation. Some previously known critical conditions become special cases in this generalized framework. Given an arbitrary control scheme, a systematic procedure is proposed to derive the critical condition for that control scheme.

Large-transverse-momentum processes: the ISR as a gluon collider

description: It is argued that, contrary to what is often said, large-transverse-momentum hadronic processes studied at the ISR have made a significant contribution to the understanding of the strong interaction and, in particular, to the development of quantum chromodynamics. In their unique role as a gluon collider the ISR have provided information that no other accelerator could have directly offered. They allowed one to probe high values of the centre-of-mass energy that were not available to fixed-target experiments. The latter, however, were more flexible and, together, they allowed for powerful explorations of the hadron structure and of the relevant dynamics in sectors such as inclusive particle production, direct photon production, and jet structure studies. It remains true that, rightly so, the ISR will be mostly remembered as the founders of a lineage that includes the proton-antiproton colliders and, today, the LHC.

description: By extending the response function approach developed in nonlinear optics, we analytically derive an expression for the non-Markovianity [Laine, et al, Phys. Rev. A 81, 062115 (2010)] in the time evolution of a system in contact with a quantum mechanical bath, and find a close connection with the directly observable nonlinear optical response. The result indicates that memory in the bath induced fluctuations rather than in the dissipation causes non-Markovianity. Initial correlations between states of the system and the bath are shown to be essential for a correct understanding of the non-Markovianity.

description: EPOS SP pays close attention to ethical responsibilities that the EPOS ERIC, as a Research Infrastructure (RI), have towards their employees, stakeholders, partners, and society in particular with respect to the sustainability phase. The main aim of Task 6.1 is to explore and collect relevant ethical implications of existing and future EPOS services in order to guide the future development of EPOS services, especially when those services are directly addressed to society (i.e. directly accessible by the general public or private sector users).

The Task 6.1 investigated the ethical and social implications of EPOS’s own perception on its scientific and technological activities, at the Thematic Core Services (TCS) level. This is done, in order develop ethical guidelines concerning the protection of personal data, management of data and data provision, service provision, data misuse, and conflicts of interests.

In the preliminary stage, documents on issues concerning research integrity, science ethics, data management, and ethics in geosciences were collected in order to carry out the structure of the questionnaire. This deliverable is focused on the questionnaire used in the ethical survey and results obtained.
