Parental guidance about drinking: Relationship with teenage psychoactive substance use
Authors: Miller Patrick , Plant Martin 
Published: July 2009

ABSTRACTParental guidance concerning alcohol was explored using data from a 2007 survey of 2179 UK school students aged 15 and 16 years. Cluster analysis based on questions about parental advice was used to establish seven student groups. Associations between groups, other family background and psychoactive substance use variables were explored. Substance use was least common amongst students whose parents discouraged drinking and those who claimed to have received no parental guidance. The heaviest substance users were teenagers from families with more favourable, tolerant attitudes to alcohol and intoxication and among students who failed to answer the questions about parental guidance. These scored highly on cannabis and other drug use. The cluster in which there was comprehensive discussion with the parents about alcohol use had an intermediate position in relation to substance use. In logistic regressions parental guidance was consistently associated with substance use with several other background variables controlled.

Published: July 2009

ABSTRACTThe frequency of health care use is crucial for adolescent well‐being and health systems. The present study was the first to test a set of variables in a representative sample of Greek adolescents in order to identify factors that predict health care use and contribute to improving health service planning. Questionnaires were administered to a random sample of adolescents (N = 1 194) aged 11–18 years and their parents (N = 973) in 2003. Data from 894 participants with full data were analyzed. Parents' education, adolescents' chronic health needs, physical well‐being and emotional/behavioural problems as well as parent‐child relationship were independent predictors of health care use, although some factors, such as gender, age, type of residence, family affluence, social support and parental health status that previous research identified as predictors were not confirmed. Beyond the need of health care, other factors also play an important role in the utilization of health services by adolescents and their families.
Short time existence and uniqueness in Hölder spaces for the 2D dynamics of dislocation densities
Authors: El Hajj A. 
Published: July 2009

In this paper, we study the model of Groma and Balogh [I. Groma, P. Balogh, Investigation of dislocation pattern formation in a two-dimensional self-consistent field approximation, Acta Mater. 47 (1999) 3647–3654] describing the dynamics of dislocation densities. This is a two-dimensional model where the dislocation densities satisfy a system of two transport equations. The velocity vector field is the shear stress in the material solving the equations of elasticity. This shear stress can be related to Riesz transforms of the dislocation densities. Basing on some commutator estimates type, we show that this model has a unique local-in-time solution corresponding to any initial datum in the space

C^{r}(\mathbb{R}^{2}) \cap L^{p}(\mathbb{R}^{2})

for

r > 1

and

1 < p < + \infty

, where

C^{r}(\mathbb{R}^{2})

is the Hölder–Zygmund space.

Résumé

Dans ce papier, nous étudions le modèle de Groma et Balogh [I. Groma, P. Balogh, Investigation of dislocation pattern formation in a two-dimensional self-consistent field approximation, Acta Mater. 47 (1999) 3647–3654] qui décrit la dynamique des densités de dislocations. Il s'agit d'un modèle bidimensionnel où les densités de dislocations satisfont un système de deux équations de transport. Le champ de vitesse dans ce système est la contrainte de cisaillement du matériau, calculée à partir de l'équation de l'élasticité linéaire. Cette contrainte de cisaillement peut être liée aux densités de dislocations par certaines transformations de Riesz. En se basant sur des estimations de type commutateurs, nous montrons que ce modèle admet une unique solution locale pour toutes données initiales dans

C^{r}(\mathbb{R}^{2}) \cap L^{p}(\mathbb{R}^{2})

pour

r > 1

AbstractNF‐κB acts as a signal transducer during tumor progression, cell invasion, and metastasis. Dimethylfumarate (DMF) is reported to inhibit tumor necrosis factor‐α‐induced nuclear entry of NF‐κB/p65. However, only a few reports suggest that DMF inhibits tumor metastasis; also the molecular mechanisms underlying the inhibition of metastasis are poorly understood. We investigated the inhibition of tumor invasion and metastasis by DMF in a melanoma cell line, B16BL6. DMF inhibited B16BL6 cell invasion and metastasis by suppressing the expression and activities of MMPs. DMF also inhibited the nuclear entry of NF‐κB/p65, thus inhibiting B16BL6 cell invasion and metastasis. These results suggest that DMF is potentially useful as an anti‐metastatic agent for the treatment of malignant melanoma.
When thinking is beneficial and when it is not: The effects of thin and round advertising models
Authors: Häfner Michael , Trampe Debra 
Published: July 2009

AbstractThis study addresses the advertising effectiveness of round and thin models. Integrating previous findings and theories, the authors predict and find that impulsive and reflective product evaluations as responses to thin and round advertisement models diverge. Specifically, four experiments indicate that impulsive product evaluations follow a priming logic, such that the beauty of the model spills over directly onto product evaluations; thin models thus produce more favorable implicit responses than do round models. For reflective product evaluations however, this pattern appears reversed. Moreover, these explicit product evaluations are mediated by campaign liking.
On values and phenomenology
Authors: Posavac Steven S. 
Published: July 2009

AbstractThis article considers the drivers of professional happiness among academic consumer psychologists, and presents a model of the recursive dynamics of favorable and unfavorable professional phenomenology, which was developed based on a series of depth interviews with a diverse set of respondents. Core professional values typically shared by consumer psychologists are discussed, as are the roadblocks that cause disconnects between individuals' values and their professional experiences. The paper additionally discusses ubiquitous experiential traps that powerfully undermine professional happiness, and concludes with prescriptive advice for creating departments that facilitate the productivity and well‐being of constituent faculty.

Authors: Wasem Jürgen , Staudt Susanne , Jahn Rebecca 
Published: July 2009

Einleitung
Seit 1.1.2009 soll die Morbiditätsorientierung des Risikostrukturausgleichs zu einem besseren Ausgleich der unterschiedlichen Morbiditätsrisiken der verschiedenen im Wettbewerb stehenden Krankenkassen der Gesetzlichen Krankenversicherung in Deutschland führen. Dieser Ausgleich, der für die Kassen risikoadäquate Zahlungen simuliert, ist nötig, um Wettbewerbsverzerrungen zu minimieren und einen ersten Schritt zur Verbesserung von Wirtschaftlichkeit und Qualität der Versorgung zu erreichen.
Wettbewerb und Markt im Gesundheitswesen: Gegen oder für Patienten?
Authors: Offermanns Guido 
Published: July 2009

Einleitung
Zur Lösung der Probleme im Gesundheitswesen wurden in den vergangen Jahren Wettbewerb und Markt als mögliche Lösungsansätze postuliert. Anreize des Wettbewerbsmodells, übertragen auf das Gesundheitssystem, könnten dazu führen, dass sowohl Krankenkassen als auch Leistungserbringer sich Vorteile zu Lasten von Patienten bzw. Versicherten verschaffen. Der Beitrag zeigt Schwierigkeiten sowie Risiken in der Anwendung des Marktmodells auf und präsentiert mögliche Lösungsansätze.
Effizienz und Incentivierung in der stationären Versorgung
Authors: Paeger Axel 
Published: July 2009

Einleitung
Deutschlands Krankenhäuser befinden sich in einer Dauerfalle. Bis einschliesslich 2008 stiegen die Personalkosten in den Salierungstarifen (BAT, TVöD, TVL) Jahr für Jahr stärker als die nahezu um null erhöhten Erlöse. Diese Schere kann nur kompensiert werden, wenn es gelingt, Rationalisierungseffekte zu erzielen. Dazu müssen die Managementstrukturen in Krankenhäusern den Marktbedingungen (Paeger, 2001a) Rechnung tragen. Weiters gehört Controlling zu den Werkzeugen jeder erfolgreichen Organisation (Paeger et al., 2002) und ihrer Führung (Schwing, 2001a).
Mit Bismarck allein wird es nicht mehr gehen!
Authors: Pfeiffer Doris 
Published: July 2009

Einleitung
Das Gesundheitssystem Deutschlands gilt als das Musterbeispiel für ein Bismarcksystem: Die Finanzierung erfolgt primär aus öffentlich-rechtlichen Beiträgen der Mitglieder, die Leistungen werden von einer Vielzahl privater wie öffentlicher Anbieter erbracht und die Steuerung erfolgt wesentlich auf Basis kollektivvertraglicher Verhandlungen zwischen Krankenkassenverbänden und Vereinigungen der Leistungserbringer. Für die grundsätzliche Typisierung des deutschen Gesundheitssystems treffen diese Aussagen weiterhin zu. Gleichwohl haben sich in den letzten Jahren die Ausprägungen der betrachteten Parameter Finanzierung, Leistungserbringung und Steuerung verändert, so dass sich das reale deutsche Gesundheitssystem in der Tendenz vom idealtypischen Bismarcksystem entfernt.

Abstract
A new version of the tectonic map for the Vendian–Lower Paleozoic structural stage of the Lena–Tunguska petroleum province is presented. The map is based on the electronic structure map at a scale of 1:1,000,000, which was the first to be compiled for the uppermost Vendian within the study area. However, no tectonic zonation was made for the deep-buried Meso-Cenozoic Yenisei–Khatanga and Vilyui depressions. The principles and methodology of mapping are given. The study presents spatial, morphological, and quantitative characteristics of the major and large structures.
Formation of the Olyutorsky–Kamchatka foldbelt: a kinematic model
Authors: Shapiro M.N. , Solov’ev A.V. 
Published: July 2009

Abstract
The Olyutorsky–Kamchatka foldbelt formed as a result of two successive collisions of the Achaivayam–Valaginsky and Kronotsky–Commander island arcs with the Eurasian margin where the two terranes docked after a long NW transport. We model their motion history from the Middle Campanian to Present and illustrate the respective plate margin evolution with ten reconstructions. In this modeling the arcs are assumed to travel on the periphery of the large plates of Eurasia, North America, Pacific, and Kula, for which the velocities and directions of motion are known from published data. The model predicts that the Achaivayam–Valaginsky arc was the leading edge of the Kula plate from the Middle Campanian to the Middle Paleocene and then moved slowly with the Pacific plate as long as the Middle Eocene when it accreted to Eurasia. The Kronotsky arc initiated in the Middle Campanian on the margin of North America and was its part till the latest Paleocene when the terrane changed polarity to move northwestward with the Pacific plate and eventually to collide with Eurasia in the Late Miocene. The predicted paleolatitudes of the Achaivayam–Valaginsky and Kronotsky–Commander island arcs for the latest Cretaceous and Paleogene are consistent with nine (out of eleven) reliable paleomagnetic determinations for samples from the two arcs. Additional changes imposed on the initial model parameters (kinematics of the large plates, relative position of the Kula–Pacific Ridge and the Emperor seamount chain, or time of active volcanism within the arcs) worsen the fit of the final reconstructions to available geological and paleomagnetic data. Therefore, the suggested model appears to be the most consistent one at this stage of knowledge.
Radon activity of faults (western Baikal and southern Angara areas)
Authors: Seminsky K.Zh. , Bobrov A.A. 
Published: July 2009

Abstract
We report results of transect radon surveys on twenty six large and small faults of different geometries in the western Baikal and southern Angara (southern Siberian craton) areas. The studied faults show up in the radon field as broad zones of high radon activity concentration, with their widths 1.4 times the widths of faulting-related deformation zones. Other things being equal, radon emanation depends on the size and slip geometry of faults and on their activity in the Cenozoic. Relative radon activity is higher in rift faults than in cratonic ones, in normal relative to strike-slip faults, and in larger and more active faults, the latter factor being the basic geodynamic control of radon emanation.
The Asachinskoe epithermal Au-Ag deposit in southern Kamchatka: physicochemical conditions of formation
Authors: Borovikov A.A. , Lapukhov A.S. , Borisenko A.S. , Seryotkin Yu.V. 
Published: July 2009

Abstract
The Asachinskoe epithermal Au-Ag deposit (southern Kamchatka) is referred to as low-sulfidation in quartz-adularia-sericite in Corbett’s classification. Research into fluid inclusions of its minerals gave an insight into the PT-conditions of formation and gas composition of ore-forming fluids as well as the vertical variations in these parameters to a depth of more than 200 m within a 2 km long horizontal site of the deposit ore zone. It is shown that mineral assemblages formed at 320 to &lt;100 °C. Ore-forming hydrothermal solutions were poor in salts (3–9.2 wt.% NaCl equiv.), with NaCl being the main component. Mineral assemblages with high contents of Au crystallized at 250–175 °C. Ore-free quartz-carbonate veins formed at 80–120 °C. High-temperature (300–320 °C) veins also lack ores. Rich gold ores were deposited in the environments where ore-bearing fluids boiled, mixing with meteoric waters.
Types of Holocene deposits and regional pattern of sedimentation in Lake Baikal
Authors: Vologina E.G. , Sturm M. 
Published: July 2009

Abstract
Results of research into recent sediments and their distribution in Lake Baikal are presented. Five areas with different mechanisms of sedimentation have been recognized: (1) deep-water plains with pelagic mud and turbidites; (2) littoral zones without turbidites; (3) underwater ridges (rises) with hemipelagic mud accumulated under calm sedimentation conditions; (4) delta (fan) areas near the mouths of large rivers, where sediments consist mainly of terrigenous material; and (5) shallow Maloe More with poorly sorted terrigenous material and abundant sand. The rate of sedimentation differs considerably in different Baikal areas. The highest rates appear near the mouths of large rivers, lower ones occur in the deep lake basins, and the minimum rates are developed on underwater ridges. A map of the distribution of Holocene sediments in Baikal has been compiled for the first time. The obtained results show that the bottom morphology significantly determines the type of sediments in the lake.
Strain amplitude-dependent attenuation ofPandSwaves in dry and water-saturated sandstone under confining pressure
Authors: Mashinskii E.I. 
Published: July 2009

AbstractThe dependence of P- and S-wave attenuation on strain amplitude and frequency has been studied experimentally in dry and water-saturated sandstone samples under a confining pressure of 20 MPa. Attenuation of P and S reflections was measured at a frequency of 1 MHz in a strain range of ε ∼(0.3−2.0) × 106. The measured P-wave attenuation (QP−1) in dry sandstone and S-wave attenuation (QS−1) in dry and saturated samples turned out to be inversely proportional to strain amplitude while QP−1 in saturated sandstone showed no strain dependence. The frequency-dependent attenuation spectra in dry and saturated sandstone differed considerably in S waves but were generally similar for P reflections. Strain amplitude variations were found out to influence the frequency dependence of attenuation and to shift the relaxation spectra of S waves toward high frequencies relative to those of P waves. As strain increased, the S-wave attenuation peak in saturated sandstone became notably (to 40%) narrower. The unusual strain amplitude-dependent behavior of attenuation may be due to joint action of viscoelastic and microplastic mechanisms. The reported results may be useful for improving geological interpretation of acoustic and seismic data.
Fayalite-sekaninaite paralava from the Ravat coal fire (central Tajikistan)
Authors: Sharygin V.V. , Sokol E.V. , Belakovskii D.I. 
Published: July 2009

Abstract
We studied ferrous paralava, a high-temperature rock, produced by complete fusion of the sedimentary protolith in the Ravat natural coal fire which has been on for over two thousand years. The paralava was sampled from the Fan-Yagnob coal deposit at the Kukhi-Malik site in the vicinity of former Ravat Village in central Tajikistan. This rock contains fayalite, sekaninaite, hercynite, Ti-magnetite, tridymite, and siliceous glass. Low-Ca pyroxene (clinoferrosilite), globules of sulfides (mainly pyrrhotite) and Fe-Ti oxides, secondary greenalite (after fayalite) and hematite are minor. Paralava includes xenoliths of partially molten clinkers (up to 20 vol.%) composed of mullite, cordierite, tridymite, and relict detrital quartz. We found relatively high Fe contents (100⋅Fe/(Fe+Mg) &gt; 60) in mafic minerals, high K2O enrichment (up to 1.4 wt.%) in sekaninaite, and an unusually low CaO content (0.5 wt.%) in the rock. The Ravat paralava appears to be derived from a mixture of pelitic rocks (50–70%) and iron-rich rocks (30–50%), but without participation of calcareous material, which explains the low CaO and the absence of plagioclase and Ca-bearing pyroxene. The primary melt was as hot as &gt;1210 °C, and the coal-fired fayalite-sekaninaite paralava crystallized at 1200–1100 °C, at a relatively low oxygen fugacity (near the QFM buffer), outside the zone of active aeration. Large-scale crystallization of ferrospinels and fayalite led to increasing Al2O3 and SiO2 in the melt whence sekaninaite and tridymite crystallized as later phases. The residual melt progressively acquired a more silicic-aluminous composition, rich in K2O, CaO, and P2O5, and became quenched to glass at &gt;1080–1090 °C, when temperature dropped abruptly, possibly, by roof collapse or opening of large cracks, as it usually happens in underground coal fires.
Conductivity of layered reservoirs in induction data processing: continuous-function approximation
Authors: Glinskikh V.N. , Epov M.I. 
Published: July 2009

Abstract
We suggest to approximate the depth-dependent conductivity of layered formations by continuous functions and use this approach to design an algorithm for 2D inversion of induction logging data. The logs represent formations consisting of alternating thin clay and sand layers of varying thickness, in which the sand layers can involve a developed invaded zone of a complex structure. Comparison of synthetic logs in models with piecewise constant and continuous approximations of conductivity shows that the continuous-function approximation is accurate within 5%, and the accuracy improves as the average conductivity of the layered formation is taken into account.
Small mammals from the early Pleistocene of the Granada Basin, southern Spain

Published: July 2009

AbstractThe Pliocene and Pleistocene continental sedimentary records of the western sector of the Granada Basin, southern Spain, consist of alternating fluvial and lacustrine/palustrine sediments. Two Quaternary sections from this sector have been sampled: Huétor Tájar and Tojaire. They have yielded remains of rodents, insectivores and lagomorphs. The presence in the Huétor Tájar and Tojaire sections of Mimomys, Apodemus atavus, Castillomys rivas and two different species of Allophaiomys, indicates an Early Pleistocene age. These deposits, which are related to a fluvio-lacustrine system, can be differentiated from an older (Pliocene) braided fluvial system. Their dating has important repercussions on the paleogeographic reconstruction of the basin. The conditions inferred from the ecological preferences of the small mammal associations are wet and cold. These associations suggest a predominance of open herbaceous habitats, followed by forested habitats; semiaquatic habitats are the least represented.
In-depth cDNA Library Sequencing Provides Quantitative Gene Expression Profiling in Cancer Biomarker Discovery
Authors: Yang Wanling , Ying Dingge , Lau Yu-Lung 
Published: July 2009

AbstractQuantitative gene expression analysis plays an important role in identifying differentially expressed genes in various pathological states, gene expression regulation and co-regulation, shedding light on gene functions. Although microarray is widely used as a powerful tool in this regard, it is suboptimal quantitatively and unable to detect unknown gene variants. Here we demonstrated effective detection of differential expression and co-regulation of certain genes by expressed sequence tag analysis using a selected subset of cDNA libraries. We discussed the issues of sequencing depth and library preparation, and propose that increased sequencing depth and improved preparation procedures may allow detection of many expression features for less abundant gene variants. With the reduction of sequencing cost and the emerging of new generation sequencing technology, in-depth sequencing of cDNA pools or libraries may represent a better and powerful tool in gene expression profiling and cancer biomarker detection. We also propose using sequence-specific subtraction to remove hundreds of the most abundant housekeeping genes to increase sequencing depth without affecting relative expression ratio of other genes, as transcripts from as few as 300 most abundantly expressed genes constitute about 20% of the total transcriptome. In-depth sequencing also represents a unique advantage of detecting unknown forms of transcripts, such as alternative splicing variants, fusion genes, and regulatory RNAs, as well as detecting mutations and polymorphisms that may play important roles in disease pathogenesis.
