The effects of reduced pH on chemical alarm signalling in ostariophysan fishes

Under laboratory conditions, we examined the effects of acute exposure to weakly acidic conditions (pH 6.0) on the ability of fathead minnows (Pimephales promelas) and finescale dace (Phoxinus neogaeus) to detect and respond to conspecific and artificial alarm pheromones. Initially, minnows and dace exhibited normal antipredator responses when exposed to conspecific alarm pheromones under normal (pH 8.0) conditions. When retested at pH 6.0, we observed no significant antipredator response. However, when returned to normal pH conditions, both exhibited normal antipredator responses. Minnows exposed to the putative ostariophysan alarm pheromone (hypoxanthine-3-N-oxide) exhibited a similar trend in behavioural response. Finally, we manipulated the pH of minnow skin extract and hypoxanthine-3-N-oxide to determine the chemical mechanism responsible for this observed loss of response. Minnows exhibited significant antipredator responses to natural and artificial alarm pheromones at normal pH conditions, but did.
KREATIVITAS DALAM PSIKOLOGI HUMANISTIK DAN IMPLIKASINYA DALAM PENDIDIKAN

Kreativitas adalah suatu gaya hidup, suatu cara dalam mempersepsi dunia. Salah satu konsep yang sangat penting dalam bidang kreativitas adalah hubungan antara kreativitas dan aktualisasi diri. Menurut psikolog humanistik aktualisasi diri ialah apabila seseorang menggunakan semua bakat dan talentanya untuk menjadi apa yang ia mampu menjadi. Pribadi yang dapat mengaktualisasi dirinya adalah seseorang yang sehat mental, dapat menerima dirinya, selalu tumbuh, berfungsi sepenuhnya, berpikiran demokratis, dan sebagainya. Teori ini sangat tepat dalam dunia pendidikan kita mengingat tujuan pendidikan nasional adalah untuk meningkatkan kualitas manusia Indonesia, yaitu manusia yang beriman dan bertakwa terhadap Tuhan Yang Maha Esa, berbudi pekerti luhur, berkepribadian, mandiri, maju, tangguh, cerdas, kreatif, terampil, berdisiplin, beretos kerja, profesional, bertanggung jawab dan produktif serta sehat jasmani dan rohani. Dengan demikian peserta didik diharapkan tumbuh dan berkembang sesuai dengan bakatnya dan tumbuh menjadi manusia yang cerdas dan kreatif.
Establishing and Retrieving Domain Knowledge from Semi-Structural Corpora

1.1 Knowledge representation The most essential part of building an expert system is the acquirement and representation of domain knowledge. In the seventies, Feigenbaum indicated the important concept of knowledge engineering. He emphasized that to utilize knowledge in problem-solving process is equally important with knowing how to solve a problem. Knowledge, according to how it is stored, can be classified to tacit knowledge and explicit knowledge. The tacit knowledge, existing in the brain of experts, can only be acquired through interviewing the domain experts. On the other hand, the explicit knowledge can be expressed clearly. Since explicit knowledge is easier to be handled, it was used in most expert systems. Knowledge representation affects how problems are solved. Human knowledge can be expressed in the form of mathematic formulas, speech, text and figures. In artificial intelligence domain, especially in expert system research, several knowledge representation forms had been proposed (Negnevitsky, 2002). They are: 1. Semantic networks (Quillian, 1965, 1968): Using directed graph to represent knwolege objects and their relationship. Each object in the network is linked to other objects by their semantic relationships. 2. Case-based format (Watson, 1997; Kolodner 1993): Knowledge is stored in the form of cases-solutions. 3. Rule-based format (Triantaphyllou & Felici, 2006): If-Then rules are stored as the knowledge source. 4. Frame-based format (Minsky, 1975): Objects are divided into several frames, and each frame contains its corresponding attribute to describe the characteristics of the objects. 5. Ontology (Munn, 2009 ; Uschold & Gruninger, 1996): It is a representation of some pre-existing domain of reality which reflects the properties of the objects within its domain in such a way that there obtains a systematic correlation between reality and the representation itself. It is formalized in a way that allows it to support automatic information processing. 22
Comparison of the Ant Assemblages in Three Phytophysionomies: Rocky Field, Secondary Forest, and Riparian Forest—A Case Study in the State Park of Ibitipoca, Brazil

Ant assemblages are almost all related with the vegetation composition and so can provide us important information for conservation strategies, which are especially relevant to an environmentally protected area. We sampled the ant fauna in three different phytophysionomies in order to verify if the composition of ant species is different among the areas, especially because one of the areas is a Rocky Field and there is little information about the ant fauna in this habitat. A total of 8730 individuals were registered and an NMDS analysis showed that the ant assemblies are different at the three phytophysionomies (Rocky Field, Riparian Forest, and Secondary Forest). This study shows that the species that compose the ant assemblies in different phytophysionomies are a reflex of the environment, supporting the hypothesis that the vegetational composition results in different compositions in the ant assembly. Vegetal composition is determinant in the formation of the litter and consequently in the occurrence of ant species that depend on this layer of organic matter for nesting and foraging.
Enhancement of Lamb Wave Imaging Resolution by Step Pulse Excitation and Prewarping

For the purpose of improving the damage localization accuracy, a prewarping technology is combined with step pulse excitation and this method is used in Lamb wave imaging of plate structures with adjacent damages. Based on the step pulse excitation, various narrowband or burst response can be derived by signal processing technology and this method provides flexibility for further prewarping approach. A narrowband signal warped with a preselected distance is then designed, and the dispersion in the response of this prewarping signal will be greatly reduced. However, in order to calculate the distance for prewarping, the first arrival needs to be estimated from the burst response. From the step-pulse response, narrowband responses at different central frequencies can be obtained, and by averaging peak-value time of their first arrivals, a more accurate estimation can be calculated. By using the prewarping method to the damage scattering signals before imaging, the imaging resolution of the delay-and-sum method can be highly enhanced. The experiment carried out in an aluminum plate with adjacent damages proves the efficiency of this method.
Does Personality effect Facial Emotion Recognition? A Comparison between the older Ekman Emotion Hexagon Test and a newly created Measure

Recent research has highlighted one possible problem faced when it comes to assessing the recognition of emotion in the human face. Previous research has suggested that the images used in the methods of assessment are becoming too familiar within the psychological research domain. They therefore suggest new ways of creating images to look at facial emotion recognition. To investigate this issue, the current study created a new emotion recognition task (Laura’s Emotion Hexagon Task) and compared this to the older Ekman’s Emotion Hexagon Test. 60 participants completed both tasks along with the IPIP-NEO. This measure looked at whether personality could predict the scores for the two facial emotion recognition tasks. Results showed that the agreeableness and extraversion personality were significant predictors of Laura’s Emotion Hexagon Task. Discussions of the findings are in relation to previous research about methodological issues surrounding facial emotion recognition, and results are discussed in relation to previous findings of how personality can effect facial emotion recognition.
Quantum trajectory approach to circuit QED: Quantum jumps and the Zeno effect

We present a theoretical study of a superconducting charge qubit dispersively coupled to a transmission line resonator. Starting from a master equation description of this coupled system and using a polaron transformation, we obtain an exact effective master equation for the qubit. We then use quantum trajectory theory to investigate the measurement of the qubit by continuous homodyne measurement of the resonator out-field. Using the same porlaron transformation, a stochastic master equation for the conditional state of the qubit is obtained. From this result, various definitions of the measurement time are studied. Furthermore, we find that in the limit of strong homodyne measurement, typical quantum trajectories for the qubit exhibit a crossover from diffusive to jumplike behavior. Finally, in the presence of Rabi drive on the qubit, the qubit dynamics is shown to exhibit quantum Zeno behavior.
Operations with Financial Derivatives of Corporations from Emerging Economies 1

As a consequence of the deepening of the international fi nancial crisis during the second semester of 2008, several productive companies from emerging economies have registered enormous losses in the foreign exchange derivatives markets. This fact points to the speculative dynamics of corporations in the fi nancial deregulated environment. This paper aims to articulate this logic of enterprises’ behavior with the crisis and to discuss some macroeconomic effects resulting from the fi nancial losses caused by speculative bets in the derivatives markets.
QUALIFICATION OF POINT CLOUDS MEASURED BY SFM SOFTWARE

This paper proposes a qualification method of a point cloud created by SfM (Structure-from-Motion) software. Recently, SfM software is popular for creating point clouds. Point clouds created by SfM Software seems to be correct, but in many cases, the result does not have correct scale, or does not have correct coordinates in reference coordinate system, and in these cases it is hard to evaluate the quality of the point clouds. To evaluate this correctness of the point clouds, we propose to use the difference between point clouds with different source of images. If the shape of the point clouds with different source of images is correct, two shapes of different source might be almost same. To compare the two or more shapes of point cloud, iterative-closest-point (ICP) is implemented. Transformation parameters (rotation and translation) are iteratively calculated so as to minimize sum of squares of distances. This paper describes the procedure of the evaluation and some test results.
Title Assessment of hybrid Phillips Curve specifications Permalink

Rudd and Whelan (2006) document evidence that the first-difference of inflation negatively depends on its own lag, and highlight that sticky price models emphasizing the role of firms’ forward-looking pricing behavior cannot be reconciled with the stylized fact. We show that the puzzling negative dependence of the first-difference of inflation on its own lag is consistent with the prediction of the hybrid New Keynesian Phillips Curve (NKPC) with lags of inflation, whereas, as it is argued, it is inconsistent with the prediction of both the purely forward-looking NKPC and its hybrid variant with a lag of inflation. Our theoretical results show that the negative dependence appears only when firms’ forward-looking pricing behavior is relatively more important than backward-looking behavior in determining inflation dynamics.

Engineering Experts ' Panel : The Status and Future of SBSE in the Software Engineering Community

Norman Fenton, Professor of Computer Science, Queen Mary, University of London, UK. During the 1970’s and 1980s there were many computer scientists and software engineers especially who dreamed of perfect solutions to complex problems based purely on mathematical semantics and logic. With the right formal notation and proof rules they imagined that it would be possible, for example, to create complex software systems automatically from mathematical specifications that were perfect in the sense of requiring no testing [1]. Although for many this dream has never died, and examples of modestly complex, verified systems and tools to support them have been developed, in practice most software engineering challenges can never support perfect solutions [2]. Since even a perfectly verified system can only have been verified against a formal specification, the need for testing still remains for such a system since there can never be a formal automated means of verifying real-world requirements. The quest for perfect solutions is, of course, also provably infeasible for a wide class of algorithmic problems, namely all of those such as the traveling salesman problem with complexity NP-complete or worse. Since such problems are pervasive and will not just go away, we have been forced to consider solutions that were less than perfect. This led to the broad discipline of approximation in algorithm design with different approaches to optimization and also probabilistic solutions [3]. It seems to me that the current discipline of search-based software engineering [4] is the inevitable extension of this work into areas beyond algorithm design, with a special emphasis on testing. The growing popularity of searchbased software engineering therefore seems to be a sign of the maturity of the entire software engineering discipline as it finally moves away from the naivety of those earlier years and confronts the reality of accepting uncertainty and approximation.

OxBlue2008(2D) Team Description

OxBlue2008(2D) is a robot football team for RoboCup 2D simulation. In this paper, the decision structure of our team will be presented, and a novel method called PSP (Policy Search Planning) is also proposed. Policy Search is used to find an optimal policy for selecting plans from a plan pool; it extends an existing gradient-search method (GPOMDP) to a MAS domain. We demonstrate how PSP can be used in RoboCup Simulation, and our experimental results reveal robustness, adaptivity, and outperformance over other methods.
Performance Analysis of OFDM System to Reduce PAPR using SLM Technique

Orthogonal Frequency Division Multiplexing is an attractive technique for wireless high-rate data transmission. The basic principle of OFDM is to split a high-rate data stream into a number of lower rate streams that are transmitted simultaneously over a number of subcarriers. Because the symbol duration increases for lower rate parallel subcarriers, the relative amount of dispersion in time caused by multipath delay spread is decreased. Inter-symbol interference (ISI) is eliminated almost completely by introducing a guard time in every OFDM symbol . The major issue in OFDM system is high PAPR which causes peak overshoots. The paper deals with elaborate study of OFDM system and least crest method of reducing peaks. The crest factor or peak-to-average ratio (PAPR) is a measurement of a signal, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform. The peak-to-average power ratio (PAPR) is a related measure that is defined as the peak amplitude squared (giving the peak power) divided by the RMS value squared (giving the average power). General Terms Orthogonal Frequency Division Multiplexing, Selective level Mapping. Peak-to-Average Power Ratio
Swedish technology teachers’ attitudes to their subject and its teaching

Abstract Background: From previous research among science teachers it is known that teachers’ attitudes to their subjects affect important aspects of their teaching, including their confidence and the amount of time they spend teaching the subject. In contrast, less is known about technology teachers’ attitudes. Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables. Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background. Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging. Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject. Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning.

Learning A Stroke‐Based Representation for Fonts

Designing fonts and typefaces is a difficult process for both beginner and expert typographers. Existing workflows require the designer to create every glyph, while adhering to many loosely defined design suggestions to achieve an aesthetically appealing and coherent character set. This process can be significantly simplified by exploiting the similar structure character glyphs present across different fonts and the shared stylistic elements within the same font. To capture these correlations, we propose learning a stroke‐based font representation from a collection of existing typefaces. To enable this, we develop a stroke‐based geometric model for glyphs, a fitting procedure to reparametrize arbitrary fonts to our representation. We demonstrate the effectiveness of our model through a manifold learning technique that estimates a low‐dimensional font space. Our representation captures a wide range of everyday fonts with topological variations and naturally handles discrete and continuous variations, such as presence and absence of stylistic elements as well as slants and weights. We show that our learned representation can be used for iteratively improving fit quality, as well as exploratory style applications such as completing a font from a subset of observed glyphs, interpolating or adding and removing stylistic elements in existing fonts.
Measurement of the e+e-→π+π-π0π0 cross section using initial-state radiation at BABAR

The process e^+e^− → π^+π^−2π^0γ is investigated by means of the initial-state radiation technique, where a photon is emitted from the incoming electron or positron. Using 454.3 fb^(-1) of data collected around a center-of-mass energy of √s = 10.58 GeV by the BABAR experiment at SLAC, approximately 150000 signal events are obtained. The corresponding nonradiative cross section is measured with a relative uncertainty of 3.6% in the energy region around 1.5 GeV, surpassing all existing measurements in precision. Using this new result, the channel’s contribution to the leading order hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon is calculated as (g^(π+π−2π^0)_μ−2)/2=(17.9 ± 0.1_(stat) ± 0. 6_(syst))×10^(-10) in the energy range 0.85 GeV < E_(CM) < 1.8 GeV. In the same energy range, the impact on the running of the fine-structure constant at the Z^0-pole is determined as Δα^(π+π−2π0)(M^2_Z) = (4.44 ± 0.02_(stat) ± 0. 14_(syst))×10^(-4). Furthermore, intermediate resonances are studied and especially the cross section of the process e^+e^− → ωπ^0 → π^+π^−2π^0 is measured.
The Role of Managers as Agents in Successful Service Innovations: Evidence from India

The article is based on a three-year study of 70 business executives belonging to 20 large organizations operating in India to identify the kind of interventions used by agents (managers) to make service innovations successful. For the purpose of analysis, the subject organizations were classified into highly successful, successful, and unsuccessful organizations on the basis of their growth rate, and their practices were analyzed to identify the role of agents in those processes or related decisions. The article also compares the practices followed by organizations based in India with global organizations operating in India to understand the contextual issues of service innovations. One person should not give orders to another person, but both should agree to take their orders from the situation. If orders are simply part of the situation, the question of someone giving and someone receiving does not come up.
