Simple model representations of transport in a complex fracture and their effects on long‐term predictions

A complex fracture model for fluid flow and tracer transport that incorporates many of the important physical effects of a realistic fracture, including advection through a heterogeneous fracture plane, partitioning of flow into multiple subfractures in the third dimension, and diffusion and sorption into fracture‐filling gouge, small altered rock matrix blocks within the fracture zone, and the unaltered semi‐infinite rock matrix on both sides of the fracture zone, was previously developed. It is common, however, to represent the complex fracture by much simpler models consisting of a single fracture, with a uniform or heterogeneous transmissivity distribution over its plane and bounded on both sides by a homogeneous semi‐infinite matrix. Simple‐model properties are often inferred from the analysis of short‐term (one to a few days) site characterization (SC) tracer test data. The question addressed in this paper is: How reliable is the temporal upscaling of these simplified models? Are they adequate for long‐term calculations that cover thousands of years? In this study, a particle‐tracking approach is used to calculate tracer test breakthrough curves (BTCs) in a complex fracture model, incorporating all the features described above, for both a short‐term SC tracer test and a 10,000‐year calculation. The results are considered the “real world”. Next, two simple fracture models, one uniform and the other heterogeneous, are introduced. Properties for these simple models are taken either from laboratory data or found by calibration to the short‐term SC tracer test BTCs obtained with the complex fracture model. Then the simple models are used to simulate tracer transport at the long‐term timescale. Results show that for the short‐term SC tracer test, the BTCs calculated using simple models with laboratory‐measured parameters differ significantly from the BTCs obtained with the complex fracture model. By adjusting model properties, the simple models can be calibrated to reproduce the peak arrival time and height of the complex fracture model BTCs, but the overall match remains quite poor. Using simple models with short‐term SC‐calibrated parameters for long‐term calculations yields BTCs with order‐of‐magnitude errors: peak arrival time is 10 to 100 times too late, and peak height is 50 to 300 times too small. On the other hand, using simple models with laboratory‐measured properties of unfractured rock samples for 10,000‐year calculations yields BTCs with peak arrivals and heights up to a factor of 50 too early and large, respectively. The actual magnitudes of the errors made by using the simple models depend on the parameter values assumed for the complex fracture model, but in general, simple models are not expected to provide reliable long‐term predictions. The paper concludes with some suggestions on how to improve long‐term prediction calculations.
Locally Regularized Linear Regression in the Valuation of Real Estate

Abstract Regression methods are used for the valuation of real estate in the comparative approach. The basis for the valuation is a data set of similar properties, for which sales transactions were concluded within a short period of time. Large and standardized databases, which meet the requirements of the Polish Financial Supervision Authority, are created in Poland and used by the banks involved in mortgage lending, for example. We assume that in the case of large data sets of transactions, it is more advantageous to build local regression models than a global model. Additionally, we propose a local feature selection via regularization. The empirical research carried out on three data sets from real estate market confirmed the effectiveness of this approach. We paid special attention to the model quality assessment using cross-validation for estimation of the residual standard error.
A model for a complex polynomial SVM kernel

SVM models are obtained by convex optimization and are able to learn and generalize in high dimensional input spaces. The kernel method is a very powerful idea. Using an appropriate kernel, the data are projected in a space with higher dimension in which they are separable by an hyperplane. Usually simple kernels are used but the real problems require more complex kernels. The aim of this paper is to introduce and analyze a multiple kernel based only on simple polynomials kernels.
Socio-economic integration of ethnic Greeks from the former USSR: Obstacles to entry into the Greek labour market

The purpose of this study is to collect data on the demographic and socio-cultural characteristics of ethnic Greeks from the former USSR and then assess the extent to which these characteristics affect their integration into the Greek labour market. To achieve this target we employ logistic regression analysis to test a model to predict the case of being employed or not by considering various factors as explanatory variables. A field survey carried out in the broad area of West Athens (total of 6,994 respondents) is used to estimate the parameters of this model. From past experience we identify 13 major variables contributing to employment or not. The results generate an overall model with six of the 13 variables statistically significant. The final part of the paper discusses the policy implications of the findings, particularly the necessity for better professional and language training of the ethnic Greek immigrants from the ex-USSR.
Corporate governance in Indonesian state-owned enterprises: Feeding with western ingredients

Corporate frauds and failures in Indonesian have continued despite the corporate governance principles of Indonesia's State-Owned Enterprises (SOEs) which have been strengthened following the Asian financial crisis of 1997/1998. This appears to indicate that corporate governance principles primarily adopted from developed Western nations are not adequate to address problems faced by SOEs in Indonesia. This primarily analytical paper evaluates the current corporate governance practices in Indonesian SOEs in light of the prevailing political and corporate culture. Given the complexity of Indonesia's political and corporate culture the adoption of corporate governance principles from Western nations as promulgated by the OECD and/or the Cadbury report are inadequate to reduce corporate mismanagement and failure among SOEs. The study also utilizes some qualitative interview data from thirty respondents at managerial level within three SOEs to aid the assessment of corporate governance practices and principles in the Indonesian context.
Gravitational, shear and matter waves in Kantowski-Sachs cosmologies

A general treatment of vorticity-free, perfect fluid perturbations of Kantowski-Sachs models with a positive cosmological constant are considered within the framework of the 1+1+2 covariant decomposition of spacetime. The dynamics is encompassed in six evolution equations for six harmonic coefficients, describing gravito-magnetic, kinematic and matter perturbations, while a set of algebraic expressions determine the rest of the variables. The six equations further decouple into a set of four equations sourced by the perfect fluid, representing forced oscillations and two uncoupled damped oscillator equations. The two gravitational degrees of freedom are represented by pairs of gravito-magnetic perturbations. In contrast with the Friedmann case one of them is coupled to the matter density perturbations, becoming decoupled only in the geometrical optics limit. In this approximation, the even and odd tensorial perturbations of the Weyl tensor evolve as gravitational waves on the anisotropic Kantowski-Sachs background, while the modes describing the shear and the matter density gradient are out of phase dephased by π /2 and share the same speed of sound.
BUSINESS STRATEGIES IN UNSTABLE INSTITUTIONAL ENVIRONMENT - CASE OF BRIC COUNTRIES

The visionary idea of BRIC 1 countries and their leading position in the development of global economy, conceived by the leading investment bank Goldman Sachs more than a decade ago, came under heavy skepticism. However, what many doubted came true. At the end of 2011 BRIC countries generated approximately 26% of global GDP, and their share in the growth of global GDP was more than 50%. The impressive growth of BRIC countries has been in large measure due to FDI inflow 2 . Intensive FDI inflow and economic development have not been followed by improved institutional efficiency. This article will show that inefficient institutions in BRIC countries have not been discouraging to MNCs3, who were predominantly led by the extent and the growth dynamics of the market. Modifications to business strategies applied in developed countries by MNCs, in order to manage unstable institutional environment in BRIC countries, will be analyzed. The conclusion is that the key modification is establishment of strong relationships with local stakeholders, in order for MNCs to gain necessary knowledge of the new business environment and create a sound basis for institutional efficiency improvement.
Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling

A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters. This design eliminates the need for employing external junctions in diplexer design, as opposed to the conventional design approach which requires separate junctions for energy distribution. A 10-pole (10th order) diplexer has been successfully designed, simulated, fabricated and measured. The diplexer is composed of 2 poles from the dual-band filter, 4 poles from the Tx bandpass filter, and the remaining 4 poles from the Rx bandpass filter. The design was implemented using synchronously and asynchronously tuned microstrip square open-loop resonators. The simulation and measurement results show that an isolation of 50 dB is achieved between the diplexer Tx and Rx bands. The minimum insertion loss is 2.88 dB for the transmit band, and 2.95 dB for the receive band.

The role of psychopathy factors in reactive aggression within a sample of prisoners

Purpose – The purpose of this paper is to examine the role of four psychopathy factors (Interpersonal Manipulation (IPM), Callous Affect (CA), Erratic Lifestyle (ELS), and Antisocial Behaviour (ASB)) and the length of incarceration in reactive aggression. The predictive effect of dissatisfaction with peer relations, childhood experiences of violence, and criminal friends on reactive forms of aggressive acts is also explored. Design/methodology/approach – In total, 129 (n=129) male prisoners incarcerated in Stargard Szczecinski Prison were recruited for the study. Cross-sectional design using self-report questionnaire of retrospective and prospective nature was utilised. Findings – Hierarchical multiple regression analysis revealed that only one psychopathy facet, IPM, forms a significant association with reactive aggression. Another accurate correlate of reactive aggression was the length of incarceration. Originality/value – The results of the present study indicate that the commonly suggested two-factor.
Bifurcation from semi-trivial standing waves and ground states for a system of nonlinear Schr\

We consider a system of nonlinear Schr\"{o}dinger equations related to the Raman amplification in a plasma. We study the orbital stability and instability of standing waves bifurcating from the semi-trivial standing wave of the system. The stability and instability of the semi-trivial standing wave at the bifurcation point are also studied. Moreover, we determine the set of the ground states completely.
Generation of phase-controlled ultraviolet pulses and characterization by a simple autocorrelator setup

A versatile femtosecond ultraviolet (UV) pulse generation, a phase modulation, and a characterization setup for coherent control applications are demonstrated. For high-performance phase control of ultrashort pulses direct in the UV a microelectromechanical-system-based 2D mirror array is applied. Multiple examples for successful phase control of ultrashort UV pulses are given, such as arbitrarily phase tailoring and pulse recompression in open and closed loop schemes. For simple and effective characterization of the generated pulses, a UV autocorrelator based on two-photon absorption in a solar blind photomultiplier is constructed. The effects of space-time coupling on split mirror autocorrelation measurements are addressed and minimized.
Low Variation in Nuclear and Mitochondrial DNA Inhibits Resolution of Invasion Pathways across the Pacific for the Coconut Rhinoceros Beetle (Scarabeidae: Oryctes rhinoceros)

The coconut rhinoceros beetle (Oryctes rhinoceros) is a severe pest of coconut and other palms that has invaded the South Pacific in the last decade. The beetle can cause great economic losses, not only to agriculture but also due to indirect impacts on tropical aesthetics and tourism. In the last decade, new invasive populations of the beetle have been detected on Guam and Oahu, Hawaii. Despite the beetle’s extensive invasion history and economic impacts, little is known about its invasion dynamics. We used 1,480 base pairs of cytochrome oxidase subunit I mitochondrial and 814 base pairs of carbamoyl-phosphate synthetase, aspartate transcarbamoylase, dihydroorotase nuclear DNA to conduct a population genetics analysis on eight beetle populations from Thailand, Vietnam, Taiwan, and China in the beetle’s native range and Palau, American Samoa, Guam, and Hawaii in the beetle’s invasive range, in an attempt to resolve invasion pathways. Genetic diversity was insufficient to generate strong evidence for O. rhinoceros movement patterns. Mitochondrial DNA provided a clear but poorly supported population structure. Although nuclear DNA proved to be more diverse, population structure lacked clear signal. This lack of diversity is congruent with a rapid, recent invasion. There appears to be no genetic exchange between populations once they establish, implying that they are rare, human-mediated dispersal events.
HALOGAS observations of NGC 5023 and UGC 2082: modelling of non-cylindrically symmetric gas distributions in edge-on galaxies

In recent years, it has become clear that the vertical structure of disc galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure of extra-planar gas has been a focus of research. The Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) survey aims to provide a census on the rate of cold neutral gas accretion in nearby galaxies as well as a statistically significant set of galaxies that can be investigated for their extra-planar gas properties. In order to better understand the vertical structure of the neutral hydrogen in the two edge-on HALOGAS galaxies NGC 5023 and UGC 2082, we construct detailed tilted ring models. The addition of distortions resembling arcs or spiral arms significantly improves the fit of the models to these galaxies. In the case of UGC 2082, no vertical gradient in rotational velocity is required in either symmetric models nor non-symmetric models to match the observations. The best-fitting model features two arcs of large vertical extent that may be due to accretion. In the case of NGC 5023, a vertical gradient is required in symmetric models (dV/dz = -14.9 +/- 3.8 km s(-1) kpc(-1)) and its magnitude is significantly lowered when non-symmetric models are considered (dV/dz = -9.4 +/- 3.8 km s(-1) kpc(-1)). Additionally, it is shown that the underlying disc of NGC 5023 can be made symmetric, in all parameters except the warp, in non-symmetric models. In comparison to the 'classical' modelling, these models fit the data significantly better with a limited addition of free parameters.
BEHAVIOR OF RED-TAILED HAWKS IN A WIND TURBINE DEVELOPMENT

Abstract Birds flying within windfarms can be killed when they collide with wind turbines. Raptors, especially red-tailed hawks (Buteo jamaicensis), are more susceptible to collisions than other birds, which may be attributable to their specific foraging and flight behavior. To more fully understand the problem, and to reduce raptor mortality, it is necessary to acquire more information on habitat use and flight behavior by raptors inhabiting windfarms. Between June 1999 and June 2000, we watched raptors for 346 hours in the Altamont Pass Wind Resource Area, the largest windfarm in North America. We recorded flight behavior in relation to characteristics of the topography such as slope aspect, elevation, and inclination and in relation to various weather variables including wind speed and wind direction. We found that red-tailed hawk behavior and their use of slope aspect differed according to wind speed. Hawks perched more often in weak winds than in strong. Red-tailed hawks were more likely to soar during low wind conditions and kite during strong wind, particularly on hillsides that faced into the wind as opposed to hillsides shielded from the wind. This is likely a result of their use of deflection updrafts for lift during flight. During our study, when winds were strong and from the south–southwest, kiting behavior occurred on south–southwestern facing slopes with inclines of greater than 20% and peak elevations greater than adjacent slopes. Accordingly, mitigation measures to decrease red-tailed hawk fatalities should be directed specifically to these areas and others fitting this general model. Wind farm managers can power down turbines at the top of these hazardous slopes when they pose the greatest danger—when winds are strong and facing perpendicularly to the slope.
The Relation between Prospective Teachers' Goal Orientations and Academic E-Dishonesty.

The purpose of this study is to investigate the relation between prospective teachers' goal orientations and academic e-dishonesty behaviors, and also the effects of their goal orientations on academic e-dishonesty behaviors. This research was conducted with correlational method. Participants of the study were 669 prospective teachers attending at Bulent Ecevit University, Eregli Faculty of Education. The data were collected with goal orientation scale and academic e-dishonesty scale. Mean and standard deviation were used for data analysis, and Pearson product-moment correlation was used for revealing the relations between variables. Additionally, stepwise regression analysis was conducted to reveal the prospective teachers' goal orientation scores' predictive power on their academic e-dishonesty scores. Finally, negative, weak, and significant relation was found between learning goal orientation and plagiarism, falsification, delinquency and unauthorized help which are sub-dimensions of the academic e-dishonesty scale. In addition positive, weak and significant relation was found between performance avoidance and all of the sub-dimensions of the academic e-dishonesty scale. The prospective teachers' performance-avoidance orientation became the most powerful and significant predictor of all of the sub-dimensions of the academic e-dishonesty scale.

BOUNDARY OBJECTS IN OPEN SOURCE DESIGN: EXPERIENCES FROM OSE COMMUNITY

The open source design (OSD) is an autonomous community dedicated to design new products, peer-to-peer, and with intellectual property copyleft. Boundary Objects (BOs) are objects to aid on the collaboration and they are used as mediators between the proposals and the repertory of each team member. This concept is consolidated on the tangible world of participatory design, but what about the digital world? How the BO had been used in Open Source Design Communities? This study aimed to investigate this aspect in a specific community named Open Source Ecology (OSE). An exploratory research was realized to identify the OSE Design Phases and the main types of boundary objects used, as well the limitations of their utilization. The results identify a gap: the members of OSE indicate low usage of Boundary Objects but considered them as essential for collaboration. The low usage was justified by complexity. The creation of prototypes or mock-ups would require more design skills than is possible for regular user; finally, the study demonstrates an indication that the proposition and use of specific BOs for OSE is a theme that must be addressed by the design management community.
