Critical review of cluster mapping studies in Poland

The concept of industrial cluster has become one of the most prominent ones both in theoretical discussions, policy making and actual business. It is generally believed that under certain conditions, efficiently performing cluster through positive externalities can become an engine of regional development. Due to potential market imperfections public intervention is frequently required. The concept has gained significance in Eastern and Central European Countries including Poland. Sound cluster-based policy requires a detailed identification of dominant cluster as well as embryonic clusters. In the past few years at the central level of Poland and at the level of some of its provinces (eg. Pomerania, Mazovia, Opole, Silesia) cluster-mapping exercises were performed as part of an effort to modify/inform regional development strategies. Apart from several domestic studies an analysis by an international team for the European Commission for the whole area of Central and Eastern Europe was carried out. The present paper critically reviews the aforementioned studies identifying major methodological bottlenecks. It seems that more emphasis should be placed on the issue of co-location of both vertically related industrial sectors as well as horizontal agglomeration. Spatial autocorrelation should also be included. Appropriate level of sectoral as well as spatial disaggregation of data is of outmost importance.
Does the bazhenovite structure really contain a thiosulfate group? A structural and spectroscopic study of a sample from the type locality

Abstract Bazhenovite was originally reported as a rare, thiosulfate-containing mineral, with the chemical formula CaS5⋅CaS2O3⋅6Ca(OH)2⋅20H2O. The structure was predicted to be layered, but no structural details were given. A crystal of “bazhenovite” from the pyritized siderite fragments occurring in the melt products of burning dumps at the type locality in the Chelyabinsk coal basin, South Urals, Russia has been examined by single-crystal X-ray diffraction and vibrational spectroscopy (FTIR and Raman). The structure was solved in space group P21/c and refined assuming twinning on {100} to a final Robs = 5.03% (731 reflections) and Rall = 6.98% (966). Although the unit-cell dimensions of the examined crystal [a = 8.391(2), b = 17.346(6), and c = 8.221(4) Å, β = 119.33(5)°, V = 1043.2(8) Å3 ] match those of the original bazhenovite description [a = 8.45(1), b = 17.47(1), and c = 8.24(1) Å, β = 119.5°, V = 1059 Å3 ], the thiosulfate group was not detected by either structural analysis or spectroscopic investigations. The structure is an alternating sequence of two kinds of layers, labeled A and B respectively, stacked along [010]. The A layer is the ordered part of the structure and consists of a linkage of Ca(OH)2(H2O)6 antiprisms and Ca(OH)4(H2O)2 octahedra. Taking into account both structural and spectroscopic results, the B layer is inferred to consist of a disordered assemblage of S32-, and to a lesser extent, S42- groups, with the possible presence of additional H2O and H2S. The possibility that bazhenovite and the mineral here examined could represent two distinct phases differing slightly from each other with respect to the thiosulfate content is discussed.
Does agriculture matter? Revisiting the farm income problem in Italy

The prevalence of low income among agricultural households has long been known as the “farm problem”. Although revisited by a number of recent studies the farm problem is still one of the rationales of agricultural policies. We apply the Oaxaca decomposition to investigate how differences in well-being between agricultural and non agricultural households in Italy are affected by the structural characteristics of households rather than specificities of the agricultural sector. Findings indicate that the latter component accounts only for one third of the difference in well-being. Therefore, tackling the adverse mix of characteristics that negatively impact well-being in agricultural households would seem to require the implementation of targeted – but not necessarily sector-specific – policies.
ACCRETION OF ROCKY PLANETS BY HOT JUPITERS

The observed population of Hot Jupiters displays a stunning variety of physical properties, including a wide range of densities and core sizes for a given planetary mass. Motivated by the observational sample, this Letter studies the accretion of rocky planets by Hot Jupiters, after the Jovian planets have finished their principal migration epoch and become parked in ∼4 day orbits. In this scenario, rocky planets form later and then migrate inward due to torques from the remaining circumstellar disk, which also damps the orbital eccentricity. This mechanism thus represents one possible channel for increasing the core masses and metallicities of Hot Jupiters. This Letter determines probabilities for the possible end states for the rocky planet: collisions with the Jovian planets, accretion onto the star, ejection from the system, and long-term survival of both planets. These probabilities depend on the mass of the Jovian planet and its starting orbital eccentricity, as well as the eccentricity damping rate for the rocky planet. Since these systems are highly chaotic, a large ensemble (N ∼ 103) of simulations with effectively equivalent starting conditions is required. Planetary collisions are common when the eccentricity damping rate is sufficiently low, but are rare otherwise. For systems that experience planetary collisions, this work determines the distributions of impact velocities—both speeds and impact parameters—for the collisions. These velocity distributions help determine the consequences of the impacts, e.g., where energy and heavy elements are deposited within the giant planets.

Music Analysis and the Social Life of Jazz Recordings

Recorded music long ago relieved us of the hard labor of performing what we wanted to hear. It relieved us of the necessity of going to a concert hall. And now it has even relieved us of any need to listen. In the sound tracking of America-in the constantly segueing fragments that fill our public and private spaces-music is merely the inescapable background, the relentless mood-setter, the arbiter and signal of proper behavior. -J.

Spatial Competition with Heterogeneous Firms

I model endogenous horizontal and vertical product differentiation with arbitrarily many heterogeneous firms. Firms are asymmetric in that they differ in their marginal costs. I prove that under an equilibrium refinement, all economically relevant firm outcomes are uniquely determined across all strict subgame perfect Nash equilibria. There are two central results. First, a firm’s price, market share, and profit are independent of its neighbors’ marginal costs, conditional on the average marginal cost in the market. Second, more productive firms are more isolated, all else equal. In particular, the distance between two firms is strictly decreasing in their average marginal cost.
Modellierung, Analyse und Berechnung der zerebrovaskularen Regulationsmechanismen

In dieser Arbeit wird sowohl ein mathematisches Modell der zerebralen Hamodynamik des Menschen als auch der Ratte entwickelt, um ein besseres Verstandnis der zerebralen Perfusion nach einem Schadel-Hirn-Trauma zu erlangen. Die Modelle sind in der Lage, die Regulationsmechanismen, die auf die kleinen zerebralen Arterien und Arteriolen wirken, die Autoregulation, die CO2 und NO Reaktivitat zu simulieren und somit den Blutflus im Gehirn dynamisch anzupassen. Weiterhin wurde spezielles Interesse auf die Ausschuttung von Katecholaminen wahrend sympathischer Stimulation und deren Effekt auf die Herzrate, das Herzzeitvolumen und den Blutdruck gelegt. Es konnen also sowohl schwere Schadel-Hirn-Verletzungen des Menschen als auch der Ratte in einer sehr realistischen Art und Weise beschrieben werden. Beide Modelle sind auf Bifurkationen untersucht worden und einige interessante Resultate und Unterschiede wurden entdeckt. Im Fall des Modells Mensch existieren Hopfpunkte. Die an diesen Punkten entstehenden periodischen Losungen sind klinisch als Lundbergsche A-Wellen oder Plateauwellen bekannt. Die Analyse des Modells Mensch hat gezeigt, das ein vasodilatorischer Stimulus notwendig ist, um das Entstehen von Plateauwellen, deren Ursache bisher noch nicht geklart war, hervorzurufen. Im Gegensatz dazu existieren keine Hopfpunkte innerhalb des Rattenmodells, d.h. es existieren dort keine Plateauwellen mit kritisch hohen Druckspitzen. Vom physiologischen Standpunkt aus fuhrt uns dieses Resultat zu der Annahme, das das hier aufgestellte System Ratte stabiler ist als das System Mensch. Weiterhin stellt sich aufgrund der Ergebnisse der Analysen beider Systeme die Frage, inwieweit ein Rattenmodell im Allgemeinen dazu geeignet ist, Vorhersagen uber das Verhalten des Menschen in einer gegebenen klinischen Situation zu treffen.
Analyzing Tenure Arrangements and Crop Rotations Using Farm Simulation and Probit Analysis

Abstract Whole farm simulation analysis and econometric techniques are employed in an analysis of crop rotations and tenure arrangement strategies. The FLIPSIM model is used to analyze a representative Texas Upper Gulf Coast rice and soybean farm. Probit analysis is then used to determine the impact of net cash farm income, land tenure, and crop rotation on probability of survival. Results suggest that, although the simulation model is useful in providing information on the effect at the farm level of following the different strategies, probit results provide greater understanding into the returns and risk inherent to each strategy.
The Rational Complementarity Problen 1

An extension of the linear complementarity problem (LCP) of mathematical programming is the so-called rational complementarity problem (RCP). This problem occurs, if complementarity conditions are imposed on input and output variables of linear dynamical input/state/output systems. The resulting dynamical systems are called linear complementarity systems. Since the RCP is crucial both in issues concerning existence and uniqueness of solutions to complementarity systems and in time simulation of complementarity systems, it is worthwhile to consider existence and uniqueness questions of solutions to the RCP. In this paper necessary and sufficient conditions are presented guaranteeing existence and uniqueness of solutions to the RCP in terms of corresponding LCPs. Using these results and proving that the corresponding LCPs have certain properties, we can show uniqueness and existence of solutions to linear mechanical systems with unilateral constraints, electrical networks with diodes, and linear dynamical systems subject to relays and/or Coulomb friction.
EVA in Economic Feasibility Study of Agricultural Water Project Investment in Crop Production Bases

There are many different methods and ways in terms of agricultural water project investment, but how to establish an efficient and scientific system to review the economic value is most important practically for investors. This study analyzes advantages and disadvantages of NPV index in current agricultural water project investments in crop producation bases, expounds in detail the EVA, which can measure the investment decision and operation performance, discusses the interconnection of EVA and common NPV, approves the equivalency between MVA and NPV in investment decision making and the equivalency of EVA and after-tax NAV and with comparison it is shown that EVA is more rational than NPV. Taking a agricultural water project as an example, it displays the EVA active function in project decision making and performance review and, further, it provides references in application of EVA system in future investment decision making.
Properties of extra-planar H I clouds in the outer part of the Milky Way

Context. There is mounting evidence for an extra-planar gas layer around the Milky Way disk, similar to the anomalous H i gas detected in a few other galaxies. As much as 10% of the gas may be in this phase. Aims. We analyze H i clouds located in the disk-halo interface outside the solar circle to probe the properties of the extra-planar H i gas, which is following Galactic rotation. Methods. We use the Leiden/Argentine/Bonn (LAB) 21-cm line survey to search for H i clouds which take part in the rotation of the Galactic plane, but are located above the disk layer. Selected regions are mapped with the Effelsberg 100-m telescope. Two of the H i halo clouds are studied in detail for their small scale structure using the Westerbork Synthesis Radio Telescope (WSRT) � and the NRAO Very Large Array (VLA) �� . Results. Data from the 100 m telescope allow for the parameterization of 25 distinct H i halo clouds at Galactocentric radii 10 kpc 1. 3c m −3 , masses up to 24 M� , and are on average in pressure equilibrium with the surrounding envelopes. Pressures and densities fall within the expectations from theoretical phase diagrams (P vs. � nh� ). The H i cores tend to be unstable if one assumes a thermally bistable medium, but are in better agreement with models that predict thermal fragmentation driven by a turbulent flow.
Changes in Greenland Halibut Growth, Condition and Fecundity in the Northwest Atlantic(Flemish Pass, Flemish Cap and Southern Grand Bank)

The Greenland halibut fishable stock has been declining substantially since late-1980s, according to both surveys and commercial fishery indices, particularly among the ages 10+, which corresponds to the females age at 50% maturity. In this paper the effect of this apparent reduction in the stock abundance on growth and reproductive parameters is examined. Among growth parameters, the analysis of the first year growth is undertaken both by cohort and by geographic areas, assuming that density dependence might be the most severe at younger age classes. This is made using records of the respective first annual ring otolith diameters. Other growth related index such as the condition factor is also analysed. Neither significant differences in the first year growth have been observed between areas analysed, nor between cohorts, during the period 1988 to 1996. Mean condition factor-at-age for ages 1 to 13 were stable during this same period. About the reproductive parameters, two aspects are considered: the interannual variations in length-at-maturity and in the potential fecundity. Female length at maturity varied between 64.5 and 69.5 cm. Female potential annual fecundity ranged between 15 000 and 158 000. It increases with female age, but the mean fecundity-at-age variations were not significant either between years of sampling or between cohorts. A common feature observed is the relative stability of those characteristic through the period analysed, which could support a certain resiliency of the life history traits in this species.
Spine metastasis from glioblastoma multiforme : A case report

Primary brain and CNS tumor incidence is approximately seven per 100,000 individuals per year worldwide. Glioblastoma multiforme metastasis outside the CNS are extremely rare, occurring in 2% of patients, so therapeutic experience with these types of tumors is limited. Extracranial bone metastasis arising from glioblastoma multiforme are uncommon and mechanism of their diffusion is not well known. We report the case of a man affected by a glioblastoma who had a dorsal spine metastasis without any brain relapse after excision of cerebral glioblastoma multiforme and adjuvant radio-chemotherapy.
Hand Washing of Nursing Students : An Observational Study

Background: Hand washing is the most important way in transmission of hospital infections and is the easiest, most efficient and cost-effective method to prevent hospital infection. Therefore, health care workers should pay attention to hand washing. Especially, because nursing spend more time with patients than any other health care workers group, their compliance with hand washing seems to be more vital. Similarly, nursing students spend a long time during their studies on clinical placements and therefore have to be exceptionally sensitive in hand washing for one more reason that is for gaining this habit in their preparation for their future nursing role. The purpose of this observational study was to determine behaviors of the nursing students towards hygienic hand washing. Method: The students observed by observers during the nursing practice. The observers were selected in each practice group. The participant of the study were 106 nursing students. Results: Students were evaluated according to the frequency of their hand washing in required situations. It was found that 50% of the students washed their hands 1-3 times. Considering the students’ reasons for hand washing; the study determined that they were washing their hands at a maximum rate of 36.2% after the medicine administration at the clinic. In terms of the duration of hand washing it was found to be lasting for 60 second or above only for a 4.7%. Conclusion: Nnursing students did not use the correct technique to wash hands in sufficient number and duration and that they usually washed their hands for the reason of protecting themselves.
Identifying causes of ground‐penetrating radar reflections using time‐domain reflectometry and sedimentological analyses

Ground‐penetrating radar (GPR) is a geophysical technique widely used to study the shallow subsurface and identify various sediment features that reflect electromagnetic waves. However, little is known about the exact cause of GPR reflections because few studies have coupled wave theory to petrophysical data. In this study, a 100‐ and 200‐MHz GPR survey was conducted on aeolian deposits in a quarry. Time‐domain reflectometry (TDR) was used to obtain detailed information on the product of relative permittivity (ɛr) and relative magnetic permeability (μr), which mainly controls the GPR contrast parameter in the subsurface. Combining TDR data and lacquer peels from the quarry wall allowed the identification of various relationships between sediment characteristics and ɛrμr. Synthetic radar traces, constructed using the TDR logs and sedimentological data from the lacquer peels, were compared with the actual GPR sections. Numerous peaks in ɛrμr, which are superimposed on a baseline value of 4 for dry sand, are caused by potential GPR reflectors. These increases in ɛrμr coincide with the presence of either organic material, having a higher water content and relative permittivity than the surrounding sediment, or iron oxide bands, enhancing relative magnetic permeability and causing water to stagnate on top of them. Sedimentary structures, as reflected in textural change, only result in possible GPR reflections when the volumetric water content exceeds 0·055. The synthetic radar traces provide an improved insight into the behaviour of radar waves and show that GPR results may be ambiguous because of multiples and interference.
Experimental analysis of an early life‐history stage: avian predation selects for larger body size of hatchling turtles

One common life‐history pattern involves an elevated rate and nonrandom distribution of neonatal mortality. However, the mechanisms causing this pattern and the specific traits that confer a survival benefit are not always evident. We conducted a manipulative field experiment using red‐eared slider turtles to test the hypothesis that diurnal avian predators are a primary cause of size‐specific neonatal mortality. Body size was a significant predictor of recapturing hatchlings alive and of finding hatchlings dead under natural conditions, but was unimportant when diurnal predators were excluded from the field site. Overall recapture rates also more than doubled when predators were excluded compared to natural conditions (72.4 vs. 34.9%). We conclude that birds are an important cause of size‐specific mortality of recently emerged hatchling turtles and that ‘bigger is better’ in this system, which has important implications for life‐history evolution in organisms that experience size‐specific neonatal mortality.
A Closed-Form Solution for Selecting Maximum Critically Damped Actuator Impedance Parameters

This paper introduces a simple and effective method for selecting the maximum feedback gains in PD-type controllers applied to actuators where feedback delay and derivative signal filtering are present. The method provides the maximum feedback parameters that satisfy a phase margin criteria, producing a closed-loop system with high stability and a dynamic response with near-minimum settling time. Our approach is unique in that it simultaneously possesses 1) a model of real-world performance-limiting factors (i.e. filtering and delay), 2) the ability to meet performance and stability criteria, and 3) the simplicity of a single closed-form expression. A central focus of our approach is the characterization of system stability through exhaustive searches of the feedback parameter space. Using this search-based method, we locate a set of maximum feedback parameters based on a phase margin criteria. We then fit continuous equations to this data and obtain a closed-form expression which matches the sampled data to within 2%-4% error for the majority of the parameter space. We apply our feedback parameter selection method to two real-world actuators with widely differing system properties and show that our method successfully produces the maximum achievable non-oscillating impedance response.
