Dynamics of Cylindrospermopsin Production and Toxin Gene Expression in Aphanizomenon ovalisporum

Aphanizomenon ovalisporum is a cylindrospermopsin (CYN)-producing cyanobacteria species that due to its increasing worldwide distribution has become an important health alarm in the last few years. Several clusters of genes involved in CYN production have been described in different CYN+ cyanobacteria genera, named aoa for Aphanizomenon and cyr for Cylindrospermopsis and others strains. The sequences of those genes are highly similar, but a rearrangement in gene order is also observed. The information on the control of CYN production by gene expression is still scarce, especially in Aphanizomenon. To obtain further information about the control of CYN production in A. ovalisporum, we have quantified the intra and extracellular CYN content, during nine days in BG11 batch cultures under optimal conditions. In parallel, the expression of four genes related to CYN synthesis, aoaA-C and cyrJ, has been analyzed by real time q-PCR. The results show a similar pattern of total CYN accumulation and gene expression. Most of the CYN is found intracellularly. Considering the high nitrogen content in the CYN molecule, we have explored if nitrogen assimilation could be related to CYN synthesis. We found inside the aoaA and aoaC sequences several putative binding domains for the global nitrogen regulator NtcA. The pattern of the ntcA expression along the culture is similar to that of CYN accumulation. Our data suggest that CYN production in A. ovalisporum seems to be controlled both by the expression of genesaoa and ntcA, this last one suggesting the influence of available nitrogen; however, other regulation mechanisms of CYN synthesis cannot be discarded.
Horizontal and vertical interseismic velocity fields in the Vanuatu subduction zone from GPS measurements: Evidence for a central Vanuatu locked zone

We analyzed interseismic velocity fields along the Vanuatu arc subduction zone from more than 45 GPS station measurements spanning 15 years. Convergence with respect to the Australian plate (AP) is normal to the trench, with amplitudes that vary greatly from a maximum of 170 mm a A1 at Vanikoro to 27 mm a A1 facing the D'Entrecasteaux Ridge (DER). Motions expressed relative to the Pacific plate (PP) highlight arc segmentation. Both the northern and southern segments undergo back-arc spreading in a roughly NE-SW direction, rotating anticlockwise and clockwise, respectively, while the central block moves eastward at a faster rate with respect to the PP than to the AP. More convergence is therefore accommodated at the eastern bound of the arc than at the Vanuatu trench. A right lateral strike-slip movement (26 ± 1 mm a A1) along a zone normal to the trench (direction N70°) is necessary to accommodate the rate variation between the central and southern parts of the arc. Horizontal and vertical rates indicate partitioning between Malekula–southernmost Santo and central-northern Santo blocks. Simple elastic modeling of the interseismic stage deformation gives locked zone characteristics (25° dip and 50 km width) and a 54 mm a A1 long-term convergence rate between the AP and the central part of the Vanuatu arc from GPS horizontal and vertical velocities estimated south of the DER. The modeling does not fit the observed velocities facing the DER, probably because it does not account for the inelastic deformation associated with buoyant ridge subduction and back-arc thrusting.
The Role of Stakeholders in Cultural Entrepreneurship Management

Abstract The skills and knowledge of the owners and employees of cultural enterprises on economic use of financial resources do not guarantee valuable artistic results. Therefore, a substantiated question has arisen: how to evaluate management in enterprises with bad financial ratios and outstanding artistic indicators. The existing definitions of cultural management (Aageson, 2008; Hagoort, 2007; Klamer, 1999; Stam, 2006; Nordman, 2003) also do not provide precise suggestions for determining the most important indicators in the evaluation of cultural management. The question is how to evaluate management in cultural entrepreneurship by determining the most important indicators for a cultural enterprise’s performance improvement. In order to define the goal of the stakeholders’ (artists, clients, media, arts scholars, third parties providing funds, cooperation partners) engagement, it is necessary to analyse the area of an enterprise’s activities, and in what way and by what kind of activities it is possible to engage the stakeholders. During the course of empirical research, it is planned to disclose, analyse and interpret the subjective reasons of pursuit. Although a numerical evaluation of stakeholders was obtained during the research and data analysis performed by Spearman’s rho correlation calculations, the obtained results during the interpretation have not been generalised. The research results reveal the role of the cultural enterprise’s stakeholders’ engagement in the evaluation of management, point to the importance of the goals’ analysis as well as the analysis of each stakeholder’s engagement, and define the criteria for evaluating the activities in cultural entrepreneurship.
The impact of CEO’s personality traits (Big 5) and human resources management practices on the innovation performance in SMEs

Personality traits have an impact on the decision making process of CEOs and are predictors of the success of innovation in SMEs. The primary objective of this study was to explore whether a relationship exists between combinations of personality traits and innovation performance in SMEs. Furthermore, the study investigated the impact of personality traits and HRM practices in combination on the firm’s innovation performance. The five-factor model of personality (Extraversion, Conscientiousness, Openness to experience, Agreeableness and Emotional Stability) was the central focus of this study. For this purpose, the sample of 35 CEOs operating in the Twente Region in the Netherlands have been surveyed and analyzed with the help of the fuzzy set qualitative comparative analysis. The findings of this study demonstrate that CEOs with high level of Extraversion and Agreeableness will have a significant impact on the innovation performance in SMEs. Furthermore, the findings highlight that HRM practices and CEOs personality traits jointly affect the firm’s innovation performance and should be regarded as complements rather than substitutes.
Analytical Electromagnetic Analysis of Multi-Phases Cage Rotor Induction Motors in Healthy, Broken Bars and Open Phases Conditions

This paper presents an analytical calculation of magnetic field and electromagnetic performances of 3-, 5-, 7-, 9-, 11-phases cage rotor induction machines in healthy, broken bars and open phase’s conditions. This model is formulated to consider all types of multi-phase/multipoles windings and used for the identification of electrical equivalent circuit (EEC) parameters It’s based on the subdomain model and the resolution of Poisson’s, Laplace’s, and Helmholtz’s equations in each subdomain issued from Maxwell equations using the method of separation of variables and Fourier series when the machines are fed with sinusoidal current and voltage. The developed analytical model permits the calculation of magnetic field distribution, eddy current, circuit model parameters, and unbalanced magnetic radial force due to broken bars, electromagnetic torque and absorbed stator current. A comparative analysis between the studied five multi-phases machines is done with considering identical power rate. The analytical results are validated by those issued from the finite-element method (FEM).
Mechanical resistance of restored teeth with extensive crown damage

Introduction. Extensively damaged teeth can be restored by different core build-up materials. The aim of this study was to examine the mechanical properties of the restored maxillary premolars with composite resin, dental amalgam and glass ionomer cement (GIC) using compressive strength test. Materials and methods. Forty extracted intact human maxillary premolars were used in this study. Artificial defect in dentin was prepared using diamond bur up to the half of the anatomic crown of the tooth. After core build-up procedure, each tooth specimen was mounted in auto polymerizing acrylic resin blocks 2 mm below cement enamel junction and they were kept in distilled water at 37°C one day before testing. Then, they were placed in specially adapted devices at the angle of 183° to the longitudinal axis and subjected to a controlled load of 1 mm per minute. Results. Results showed that the best mechanical properties had samples restored with resin composite (492.5 N), then with amalgam (341.2 N) and glass ionomer cement (171.8 N). Comparing the fracture force using ANOVA, there was statistic significance between these groups (p<0.01). There were significant differences among control group and restored teeth with composite resin, amalgam and GIC. There was no significant difference in values of fracture forces between groups with composite resin and amalgam. The fracture force corresponding to the teeth restored with the GICs was significantly lower compared to the control group and the group with composite resin and amalgam. Conclusion. Satisfactory mechanical properties of restored premolars were obtained using composite resin and dental amalgam as a core build-up material.
Procyclicality, Fiscal Dominance, and the Effectiveness of Fiscal Policy in Egypt

This paper uses Structural Vector Autoregressive (SVAR) models to study the effectiveness of fiscal policy in stabilizing the real GDP. To do so, it first addresses the cyclicality of fiscal policy in Egypt since the early 1980s. Then, it tackles the fiscal dominance. Once the stage is prepared, it moves on to investigate the effectiveness of the fiscal policy. The paper concludes that the relationship between the fiscal policy and the economic activity is very week and it goes from the former to the later while the relationship between the fiscal policy and the monetary policy is strong and it also goes from the former to the later. This aggravated the economic instability and made the economy more prone to a boom-bust cycle
Using text in visualizations for micro/macro readings

This paper presents techniques for creating micro/macro encoding in text visualization using text and font-attributes. Alphanumeric Marks increase information density in standard plots using alphanumeric markers to provide additional micro-level information. In-Context Representations layer additional macro-level data into traditional text lists and blocks using font-based attributes to make high-level patterns easily perceivable. This is a work in progress with novel design contributions regarding generalized use of text and font attributes in visualization.
Agility Across Time and Space - ReadingSample

In this chapter we present our experiences with working with subcontractors in distributed Scrum teams. The context of our experiences is a medium size software service provider company. We present the way the subcontractors are selected and how Scrum practices can be used in real-life projects. We discuss team arrangements and tools used in distributed development teams highlighting aspects that are important when working with subcontractors. We also present an illustrative example where different phases of a project working with subcontractors are described. The example also provides practical tips on work in such projects. Finally, we present a summary of our data that was collected from Scrum and non-Scrum projects implemented over a few years. This chapter should provide a practical point of view on working with subcontractors in Scrum teams for those who are considering such cooperation.
Evaluation of Rheological and Image Properties of Styrene-Butadiene-Styrene and Ethylene-Vinyl Acetate Polymer Modified Bitumens

Received 6 March 2010; accepted 28 January 2011DOI 10.1002/app.34282Published online 7 July 2011 in Wiley Online Library (wileyonlinelibrary.com). ABSTRACT: This article presents a laboratory evaluationof conventional, fundamental, rheological, and morpholog-ical characteristics of styrene-butadiene-styrene (SBS) andethylene vinyl acetate (EVA) polymer modified bitumens.Polymer modified bitumen (PMB) samples have been pro-duced by mixing a 50/70 penetration grade unmodified(base) bitumen with SBS and EVA copolymer at differentpolymer contents. The fundamental viscoelastic propertiesof the PMBs were determined using dynamic (oscillatory)mechanical analysis and presented in the form of tempera-ture and frequency-dependent rheological parameters.The morphology of the samples as well as the percentarea distribution of polymers throughout the base bitumenhave been characterized and determined by means offluorescent light optic microscopy and Qwin Plus imageanalysis software, respectively. The results indicated thatpolymer modification improved the conventional andrheological properties of the base bitumen. It was alsoconcluded that the temperature and frequency had a sig-nificant effect on complex modulus of PMBs. The behaviorof EVA and SBS PMBs had exhibited quite difference at50 C. Moreover, it was found out that at low polymercontents, the samples revealed the existence of dispersedpolymer particles in a continuous bitumen phase, whereasat high polymer contents a continuous polymer phase hasbeen observed.
Dynamics in Nonlinear Schrödinger Equation with dc bias: From Subdiffusion to Painlevé Transcendent

Dynamics of the nonlinear Schrodinger equation in the presence of a constant electric field is studied. Both discrete and continuous limits of the model are considered. For the discrete limit, a probabilistic description of subdiffusion is suggested and a subdiffusive spreading of a wave packet is explained in the framework of a continuous time random walk. In the continuous limit, the biased nonlinear Schrodinger equation is shown to be integrable, and solutions in the form of the Painleve transcendents are obtained.
AIMS AND FUNCTIONS OF THE NOFDP IDSS

The August 2005 flood in the Alpine Region was just one of a series of severe flood events in recent times. However, it caused damage amounting to several hundreds of million Euros and casualties. Again the public demanded for better future flood protection supported by technical solutions. At the same time, politicians realised again the difficulties and existing conflicts in finding appropriate and effective solutions. The nofdp (nature-oriented flood damage prevention, www.nofdp.net) project is embedded in the Interreg III B programme, an initiative of the European Commission aiming at the promotion of interregional cooperation within Europe. The project has the ambitious target to harmonise and balance the various conflicts of interests in flood management. One of the projects objectives is to develop a modular and integrative Information and DecisionSupport System (IDSS). The IDSS aims to support water managers in developing regional flood damage prevention strategies by means of a progressive decision making process. This technique ensures to achieve a balanced view in the planning procedure. The methodology of a priori and progressive decision-making and the resulting IDSS concept is presented.
Does the market kill bad ideas? An institutional comparision of committees and markets in network industries

The paper analyzes the problem of protocol coordination between two firms, where one firm has private information about its own protocol. The institutional characteristics of the market and the class of strategies adopted by the firms admit multiple equilibria in the market. Of these, one particular equilibrium has an interior information revelation cutoff for the firm with private information. This demonstrates that the market might not be able to "kill bad ideas", but it does "reward good ideas". In contrast, the institutional design of the committee ensures that the same class of strategies gives rise to a unique equilibrium in the committee, with the informed firm revealing all private information. The committee game results generalize easily to multiple periods as well as to multiple firms and is robust to an exit option. The market game result holds for a certain range of parameter values for multiple firms.
PITCH RANGE AND VOWEL DURATION IN THE SPEECH OF CHILDREN WITH WILLIAMS SYNDROME

This paper reports the pitch range and vowel duration data from a group of children with Williams syndrome (WS) in comparison with a group of typically developing children matched for chronological age (CA) and a group matched for receptive language abilities (LA). It is found that the speech of the WS group has a greater pitch range and that vowels tend to be longer in duration than in the speech of the typically developing children. These findings are in line with the impressionistic results reported by Reilly, Klima and Bellugi [17].
Sexual trauma type and its relation to alexithymia, dissociation and posttraumatic stress disorder symptoms among women survivors

Purpose: The aim of the study was to examine the strength of association between posttraumatic stress disorder (PTSD) as well as alexithymia and dissociation relative to persons, who have experienced one of the following types of trauma: trauma associated with rape or sexual violence (ST), other kinds of trauma associated with being a victim of a fire or an accident (NST). Method: The total number of participants amounted to 117 women, among whom 39 fell victims to sexual abuse (ST), 39 experienced non-sexual trauma (NST), and 39 denied ever having come through a traumatic situation (NT). Seventy five women (64.1%) admitted that they suffered from PTSD. Three standardised instrument were used to assess alexithymia (TAS-26), dissociation (CES) and Posttraumatic Stress Disorder (PDS). Results: The ST group is characterised by significantly higher levels of alexithymia, but only in the form of identifying and describing one’s own emotions. The surprising finding was that ST and NT groups reported slightly different levels on the general scale of dissociation, which can be explained by the fact that NST group showed significantly more intensive dissociative tendencies in the form of self-absorption, while ST showed it in the form of depersonalisation and amnesia. In the ST group, significantly more serious PTSD-symptoms were confirmed, particularly regarding the avoidance of stimuli related with trauma. These findings suggest that trauma-type (sexual/non-sexual) might be a key factor determining the extent, kind and intensity of trauma-related disorders. Conclusions: Dissociation and alexithymia are very important to the development and maintenance of the symptoms of PTSD. The high levels of alexithymia were associated with more serious problems of affective arousal and regulation of affect after trauma.
Technical Analysis, Business Cycle, and Stock Market Returns

This article provides nine profitable timing strategies based on the technical analysis of two specific macroeconomic variables (i.e., capacity utilization rate and unemployment rate). The success of our strategies is explained by the high persistence in the business cycle, which allows the two macroeconomic variables to anticipate future business conditions better than the S&P500 index. Furthermore, they create additional value in timing the market as the changes in stock prices reflect subsequent changes in business conditions.
LINEAR THEORY OF FAST RECONNECTION AT AN X-TYPE NEUTRAL POINT

LINEAR THEORY OF FAST RECONNECTION AT AN X-TYPE NEUTRAL POINT I. J. D. CRAIG Department of Mathematics, University of Waikato, Hamilton, New Zealand AND A. N. McCLYMONT Institute for Astronomy, University of Hawaii, Honolulu, HI 96822 Received 1992 March JO; accepted 1992 September 3 ABSTRACT A linear theory is developed for the dissipation of the free magnetic energy in small disturbances imposed on the potential field of an X-type neutral point. An eigenmode analysis, using cylindrical coordinates centered on the neutral point, extends the work of Craig & McClymont (1991) to include non-azimuthally symmetric perturbations on the flux function. We demonstrate that all physically significant disturbances, both reconnec­ tive and nonreconnective, decay resistively on a "fast" time scale J ln I'/ I, where I'/ is the nondimensional resistivity. Thus resistive diffusion is remarkably effective as a dissipation mechanism for all classes of pertur­ bation not only those modes which induce changes in the field topology. The fundamental reason for the fast dissipation is the focusing of wave energy onto the neutral point by the gradient in Alfven speed. This occurs for all types of disturbances launched from the outer boundary, but reconnective modes propagate purely radially while nonreconnective modes correspond to waves with an azi­ muthal motion and a smaller wave speed in the radial direction. Dissipation of reconnective disturbances takes place in a diffusion region of diameter ,;:::,111 12 around the neutral point, on a time scale oc Jln 11J , but nonreconnective perturbations decay before penetrating to the neutral point, because of the increased path lengths due to their azimuthal motion. These modes release their energy in an annulus of radius ,;::;, [(m3 / 4k)11] 1 12, where m and k are azimuthal and radial wavenumbers: because of their longer transit time, non­ reconnective waves decay on a J ln I'/ 1 3 time scale. We conclude by discussing the significance of the linear theory within the general context of steady state and dynamic reconnection studies. It is pointed out that, dynamically, disturbances can be expected to focus explosively in the vicinity of the neutral point. This suggests the formation of a "flux pile-up" current layer in which the bulk of the magnetic energy is released as heat rather than kinetic energy of mass motion. Subject heading: MHD
Classroom Management in Foreign Language Education: An Exploratory Review.

This review examines studies in the area of classroom management in foreign language education. It is organized into three large areas: The first area focuses on the distinctive characteristics of foreign language instruction that are more likely to impact classroom management in foreign language classes. The second area provides a description of classroom management issues that foreign language teachers usually encounter in their practice; and the third area centers on the different alternatives to reduce the negative impact of classroom management on foreign language classes. Conclusions suggest a need for more research particularly on the relationship between classroom management and aspects such as target language use and teaching methods.
12 Law and Equity Markets : A Simple Model

We analyze how the law and its enforcement affect equity market equilibrium. Improvements in the legal system, while invariably associated with broader equity markets, have different effects on equity returns depending on the institutional change considered and on the degree of international stock market segmentation. The model is useful to interpret the results of recent e mpirical work, such as La Porta et al. (1997) and Lo mbardo and Pagano (1999). In particular, it can rationalize the observed cross-country pattern, whereby better institutions are associated both with broader equity markets and higher risk-adjusted returns on equity.
