The research problem is the lack of motivation and attention of students in the teaching and learning process of Geography and the Component Display Theory (CDT) model has not been applied in Syaloom Christian High School in Manado City. This study aims to determine the effect of the CDT learning model in improving learning outcomes in the Geography subjects of Syaloom Christian High School students in Manado City. The results were analyzed by statistical t-test obtained by the value of t count = 11.896 giving a recommendation that the research hypothesis is different. This value explains the differences in the learning outcomes of students in the experimental group Geography with the CDT learning model better than the control group learning outcomes without using the CDT learning model when viewed from the average value. Therefore, the CDT learning model that was applied to the experimental group students had a positive effect on improving student learning outcomes in Geography subjects.

Full textAbstract:
In this study, we define a metric for quantifying the cognitive efficiency (CE) of displays in human–machine systems and examine correlations between the metric and multitasking performance in a driving simulation. The CE metric uses existing theory and methods to quantify both display informativeness (increasing CE when displays convey more useful information to human operators) and required mental resources (increasing CE when fewer human mental resources must be allocated to the display). A divided-attention task set involved processing different visual displays to inform route selection while concurrently avoiding obstacles in a simulated driving study. Measures of multitasking performance as well as informativeness and resources required were collected while participants processed each display. These measures were combined in different ways to construct several CE metrics, which were then evaluated with correlation analyses to determine which combinations were most predictive of multitask performance. Generally, CE constructs involving measures of subjective workload correlated with performance indices more strongly than did physiological indicators. Importantly, some CE metrics showed higher correlations with performance indices than did constituent component measures, illustrating the value of the combined construct. This work describes a simple yet powerful way to quantify the efficiency of displays for human–machine systems in demanding multitask environments.

Full textAbstract:
Discrete unstable modes of hypersonic laminar boundary layers, obtained from an eigenvalue analysis, provide insight into key transition scenarios. The character of such modes near the leading edge is often identified with the corresponding asymptotic free-stream behaviour of acoustic, vortical or entropic (thermal) content, which we designate fluid-thermodynamic (FT) components. In downstream regions, however, this direct one-to-one correspondence between discrete modes and FT components does not hold, since FT components interact in well-defined ways with the basic state and with each other (even under linear scenarios). In the present work, we perform an FT decomposition of discrete modes using momentum potential theory, to yield a physics-based analysis that complements linear stability theory in the linear regime, and seamlessly extends to the nonlinear domain where direct numerical simulations are appropriate. Linear and nonlinear saturated disturbance effects, different forcing types and wall thermal conditions are considered, with emphasis on phenomena occurring near stability-mode synchronization locations. The results show that, in the linear regime, each discrete mode contains all FT components, whose relative amplitudes vary with streamwise distance. Vortical components are always the largest, followed by thermal and acoustic components. These latter two show distinct fore and aft signatures near mode synchronization. The vortical component displays a series of rope-shaped recirculation-cell patterns across the generalized inflection point. However, both acoustic and thermal components display ‘trapped’ structures. The former contains an alternating monopole array between the wall and the critical layer, while the latter is confined to an undulating region between the wall and a wavy locus straddling the generalized inflection point. Nonlinear saturation in the region of Mack-mode growth further strengthens the rope-shaped structures in the vortical component and higher harmonics appear, whose form and location depend on the specific component. Wall cooling modifies the eigenfunctions such that the acoustic component accounts for more of its composition, consistent with its destabilization. Analysis of energy interactions among the FT components indicates that, even though the vorticity component is the largest, the thermal component induces the most significant source term for the growth of acoustic perturbations, possibly due to the trapped nature of both.

Full textAbstract:
Based on a large component QCD derived directly from full QCD by integrating over the small components of quark fields with |p| < E + mQ, an alternative quantization procedure is adopted to establish a basic theoretical framework of heavy quark effective field theory (HQEFT) in the sense of effective quantum field theory. The procedure concerns quantum generators of Poincaré group, Hilbert and Fock space, anticommutations and velocity superselection rule, propagator and Feynman rules, finite mass corrections, trivialization of gluon couplings and renormalization of Wilson loop. The Lorentz invariance and discrete symmetries in HQEFT are explicitly illustrated. Some new symmetries in the infinite mass limit are discussed. Weak transition matrix elements and masses of hadrons in HQEFT are well defined to display a manifest spin-flavor symmetry and 1/mQcorrections. A simple trace formulation approach is explicitly demonstrated by using LSZ reduction formula in HQEFT, and shown to be very useful for parametrizing the transition form factors via 1/mQexpansion. As the heavy quark and antiquark fields in HQEFT are treated on the same footing in a fully symmetric way, the quark–antiquark coupling terms naturally appear and play important roles for simplifying the structure of transition matrix elements, and for understanding the introduction of "dressed heavy quark"–hadron duality. In the case that the "longitudinal" and "transverse" residual momenta of heavy quark are at the same order of power counting, HQEFT provides a consistent approach for systematically analyzing heavy quark expansion in terms of 1/mQ. Some interesting features in applications of HQEFT to heavy hadron systems are briefly outlined.

This experiment tested a detection theory model of visual signal detection and recognition. The task employed a visual display consisting of analog gauges arranged in a horizontal line. The signals to be detected and identified were three unique patterns of gauge values embedded in noise. After viewing the display the observers either reported that any of the signals had occurred (1-of-m signal detection) or specified which of the signals (if any) had occurred (1-of-m signal recognition-detection). The results indicated that performance on 1-of-m recognition and detection tasks can be predicted from performance on the component single-signal detection tasks.

Full textAbstract:
We demonstrate the advantages of adopting a wave-vector-based coordinate system (WCS) for the application of perturbation theory to derive and display approximate expressions for qP- and qS-wave polarization vectors, phase velocities, and group velocities in general weakly anisotropic media. The advantages stem from two important properties of the Christoffel equation when expressed in the WCS: (1) Each element of the Christoffel matrix is identical to a specific stiffness component in the WCS, and (2) the Christoffel matrix of an isotropic medium is diagonal in the WCS. Using these properties, one can easily identify the small components of the Christoffel matrix in the WCS for a weakly anisotropic medium. Approximate solutions to the Christoffel equation are then obtained by straightforward algebraic manipulations, which make our perturbation theory solution considerably simpler than previously published methods. We compare and contrast our solutions with those discussed by other workers. Numerical comparisons between the exact, first-order, and zero-order qS-wave polarization vectors illustrate the accuracy of our approximate formulas. The form of the WCS phase-velocity expressions facilitates the derivation of closed-form, first-order expressions for qP- and qS-wave group-velocity vectors, providing explicit formulas for the direction of propagation of seismic energy in general weakly anisotropic media. Numerical evaluation of our group-velocity expressions demonstrates their accuracy. We discuss problems with the approximate qS-wave group velocities and polarizations in neighboring directions of singularities. Standard methods are used to transform our solutions from the WCS to the acquisition coordinates, as illustrated by application to orthorhombic symmetry.

This study mainly aims to describe and analyze the environmental cares of the 6th class elementary school students in Ruteng. Three attitude components were assessed: cognition, affection, and conation components. A descriptive qualitative research were designed through survey method which involved the 6th grade students as the population from elementary schools in Ruteng. Simple random sampling was employed to determine four elementary schools as samples; those schools were SDK Ruteng 1, SDK Ruteng 3, SDI Wae Ri'i, and SDI Karot. The data were collected through a questionnaire while the data analysis technique was based on Miles and Huberman models which covers reduction, data display, and conclusion / verification. The data were validated in triangulation test, namely: theory triangulation, data triangulation, and expert triangulation. The results of the study showed that the average score of environmental care attitudes of the 6th students’ in Ruteng was 77.81 in a good category. Meanwhile, the average of attitude score components covering the cognition component was 80.3 in the excellent category, affection component was 80.05 in the excellent category, and the conation component was 73.1 in the good category. Based on four elementary school samples, those results were consistently found and the environmental care score on the conation component was lower than the other two components. This indicates that cognitive and affective factors do not necessarily affect on students' conations. Even though the students have awareness (cognition) and feelings (affection) related to the surrounding environmental problems, these are not visible in their daily behavior (conation).

As organizations continue to implement new technology solutions, the need for both technology training and examining technology acceptance of new implementations are necessary to determine the success or failure of a project. Unfortunately, instructional design considerations generally do not address technology acceptance, and leading technology acceptance models only classify training as an external variable or facilitating condition, with limited consideration in prior research. In this paper, we examine potential integration points between instructional design theory and technology acceptance. Specifically, we examine prior research on self-efficacy, Kirkpatrick’s Model for Evaluating Training, Merrill’s Component Display Theory, and Merrill’s First Principles of Instruction.

The electrodynamic response in the normal and superconducting ground states of K 3 C 60 and Rb 3 C 60 is reviewed. The normal state optical properties are rather unconventional since they can be explained only by considering the interplay of a Drude-like and a mid-infrared absorption component. On the other hand, the superconducting state optical properties are more straightforward since they display clear fingerprints related to the conventional weak coupling limit of the BCS ground state. Our optical spectra clearly display a well developed excitation due to the superconducting gap. Moreover, the analysis of our optical results in the superconducting state within the standard Eliashberg electron–phonon theory of superconductivity strongly supports a pairing mechanism mediated by high frequency intramolecular phonon modes.

MXenes are two-dimensional nanomaterials isolated from MAX phases by selective extraction of the A component—a p-block element. The MAX exfoliation energy, Eexf, is considered a chemical descriptor of the MXene synthesizability. Here, we show, by density functional theory (DFT) estimations of Eexf values for 486 different MAX phases, that Eexf decreases (i) when MAX is a nitride, (ii) when going along a metal M component d series, (iii) when going down a p-block A element group, and (iv) when having thicker MXenes. Furthermore, Eexf is found to bias, even to govern, the surface chemical activity, evaluated here on the CO2 adsorption strength, so that more unstable MXenes, displaying larger Eexf values, display a stronger attachment of species upon.

Language assessment is the significant component of foreign language learning/ teaching. An aim of language assessment is to find about how much the process of education improves learners’ knowledge of the target language. One alternative to standardized testing, Dynamic Assessment derived from Vygotsky’s sociocultural theory offers a new insight into the field of assessment through integrating instruction and assessment. Dynamic assessment is a method of conducting a language testing to investigate and highlight the individual learner's possessed skills and potential development. The present study is going to display an overview of the importance of dynamic assessment in L2 learning, emphasizing the origins and principal concepts involved in the process. The study highlights the derivation of dynamic assessment from Vygotsky’s prominent sociocultural theory. Then it brings about an introduction to zone of proximal development the concept of which learner's cognitive development results through the application of dynamic assessment. Later the study discusses dynamic assessment in detail and introduces its differences with the traditional testing formats as well as introducing forms of dynamic assessment.

Full textAbstract:
The paper shows how the surveying of power quality in microgrids working under unbalanced harmonic distorted operating states with possible voltage dips and voltage swells existence can be accomplished implying a small amount of time and measurement activities. The surveying methodology uses the disturbances propagation phenomenon to determine the power quality indices in all of interest nodes of the microgrid utilizing the voltages and currents characteristics in one or several strategic nodes. The disturbances propagation is based on the sequence component theory applied for all detected harmonics and for the microgrids components. The proposed surveying methodology was implemented in a virtual instrument capable to acquire the voltages and currents waveforms, to analyze them in order to identify the disturbances characteristics, to calculate the disturbances propagation and display the power quality indices in all of interest nodes of the microgrid. The virtual instrument was tested using several microgrid topologies and scenarios.

Full textAbstract:
Despite being a fundamental electronic component for over 70 years, it is still possible to develop different transistor designs, including the addition of a diode-like Schottky source electrode to thin-film transistors. The discovery of a dependence of the source barrier height on the semiconductor thickness and derivation of an analytical theory allow us to propose a design rule to achieve extremely high voltage gain, one of the most important figures of merit for a transistor. Using an oxide semiconductor, an intrinsic gain of 29,000 was obtained, which is orders of magnitude higher than a conventional Si transistor. These same devices demonstrate almost total immunity to negative bias illumination temperature stress, the foremost bottleneck to using oxide semiconductors in major applications, such as display drivers. Furthermore, devices fabricated with channel lengths down to 360 nm display no obvious short-channel effects, another critical factor for high-density integrated circuits and display applications. Finally, although the channel material of conventional transistors must be a semiconductor, by demonstrating a high-performance transistor with a semimetal-like indium tin oxide channel, the range and versatility of materials have been significantly broadened.

PurposeSet in the newly emerging hybrid product research stream, and reflecting trends towards multi‐national production and sourcing, this paper aims to present a three‐country study on perceived quality and image of automobiles “made in and for” Southeast Asia.Design/methodology/approachThe authors used a multiple cue design in the stimulus definition, reflecting assembly and component origin plus warranty level. Actual car owners were targeted, thereby adding to a relatively low number of studies requiring actual prior purchase. The related face‐to‐face interviews in the local languages resulted in 720 usable questionnaires.FindingsCountry‐of‐assembly is shown to affect perceived quality as well as perceived image. Warranty extension can moderate the quality effects to some extent, whilst buyers of luxury models display a smaller positive home bias in terms of perceived image than those of non‐luxury models. Such home region bias is not demonstrated to be significant for country‐of‐components.Research limitations/implicationsThe paper contributes towards ongoing theory‐building, especially with regards to an optimum level of origin cue decomposition. It also establishes the importance of adding image perception measurement to the arsenal of origin researchers normally focused on quality effects.Practical implicationsManagers need to make strategic decisions on the decomposition of product origin cues, reflecting consumers' abilities to notice several such cues. The selected product origin cues must then be supported with appropriate communications strategies.Originality/valueFor the first time, origin effects are demonstrated for the Southeast Asia region. The paper establishes the significance of country‐of‐target and contributes to research on the ever more complex product origin construct.

We study homogeneous normal systems of bosons under the influence of interparticle forces with a strongly repulsive component at short relative particle-particle distances. The repulsion prevents short-ranged exchange between the bosonic constituents in the quantum fluid. Consequently, the bosons remain distinguishable at temperatures far below the classical high-temperature regime. At these low temperatures such fluids and liquids display nevertheless distinct quantum effects due to quantum-mechanical phase-phase correlations. Typical examples are liquid para-hydrogen and fluid 4 He under certain thermodynamic conditions. The study employs Correlated Density-Matrix theory and Path-Integral Monte-Carlo simulations.

Purpose: Analysis of modern methods (theory) of composition as a priority motivation of artistic and creative thinking in the process of architectural activity. Study of the influence of the complex properties of manufacturability on the nature of the formation of composite solutions of architectural systems. Methods and materials: dialectical approach, generally accepted logical research methods (analysis, system approach, generalization) and their synthesis using relevant information materials.Results: the basic means, regularities and principles of composition that determine the features of the formation of architectural systems are established. The analysis of the action of the basic (canonical) law of architectural composition and the conditions for the formation of a holistic and unified compositional solutions. The conceptual apparatus of the category (complex property) of “manufacturability” as a subject feature of the features of manufacturing, transportation, construction and operation of the architectural system is given. The direct nature of the interaction of “canonical” types (functional, constructive, artistic and aesthetic) and technological components in the tectonic display of the properties of the architectural system is established.Conclusions: Manufacturability of architectural systems formation is an equivalent component (in relation to the constructive, functional and artistic-aesthetic components) of a single and integral compositional solution. Indicators of the complex properties of manufacturability largely determine the functional quality of architectural systems.

This research stems from the casual observation that the image of a television screen with 18° geometric ®eld of view (FOVg) as seen on a real television with 17° real FOV appears much “nearer” than the real television<Eth>as much as 98% closer. Does the image appear “nearer” because the distance to the real television is misjudged or is a mental model of a virtual subjective self-location created? Either way, all the projective mapping in the world, whether only in the z plane or in all x, y, and z planes, is irrelevant to explain this powerful perceptual or cognitive effect that the neglected variable of FOV has on self-location in virtual space. Accurate perception of the scene and precise self-location in virtual environments is the goal of accurate perspective geometries, scene computation, and helmet-mounted display (HMD) optics. Yet, as research has already clearly shown, accurate geometric projection is no guarantee of accurate perception: for instance, images viewed exactly at their proper projection points have repeatedly been seen at distorted distances or inaccurate directions. In addition to precise engineering, it is important to understand the psychology of selflocation, also called egocenters, to obtain an understanding of virtual space. A new theory, Cognitive Frame Theory, is proposed to deal with cognitive modi®cations of perception in a way that emphasizes the importance of self-location. Cognitive Frame Theory builds on the phenomenal geometry underlying self-location perceptions: the localization of objects in space requires a combination of perceived distance, perceived direction, and the perception of the position or motion of the self. A fundamentally novel component of the theory suggests that observers use their natural ®elds of view of 120° vertical by 180° horizontal as the primary standard for interpreting visual displays and their self-location in the space of those displays.

It is shown that W. S. Allen’s theory of a ‘contonation’, derived from Vedic descriptions, accounts for the apparently divergent ‘tone’ and ‘stress’ rules (respectively) for ancient Greek and Latin, as well as, by extension, classical Sanskrit. Historically, Greek and Latin show evidence of an active stress component in their accentuation in the weakening grade of adjacent vowels, an effect that appears not to be present during the classical period. It turns out that all three classical languages display patterns of accentuation in their received grammatical traditions which can be formulated in terms of a 'recessive' rule when the role of quantity is factored in.

Abstract. In climate studies, detecting spatial patterns that largely deviate from the sample mean still remains a statistical challenge. Although a Principal Component Analysis (PCA), or equivalently a Empirical Orthogonal Functions (EOF) decomposition, is often applied for this purpose, it provides meaningful results only if the underlying multivariate distribution is Gaussian. Indeed, PCA is based on optimizing second order moments, and the covariance matrix captures the full dependence structure of multivariate Gaussian vectors. Whenever the application at hand can not satisfy this normality hypothesis (e.g. precipitation data), alternatives and/or improvements to PCA have to be developed and studied. To go beyond this second order statistics constraint, that limits the applicability of the PCA, we take advantage of the cumulant function that can produce higher order moments information. The cumulant function, well-known in the statistical literature, allows us to propose a new, simple and fast procedure to identify spatial patterns for non-Gaussian data. Our algorithm consists in maximizing the cumulant function. Three families of multivariate random vectors, for which explicit computations are obtained, are implemented to illustrate our approach. In addition, we show that our algorithm corresponds to selecting the directions along which projected data display the largest spread over the marginal probability density tails.

Emotion is a cultural and psychobiological adaptation mechanism which allows each individual to react flexibly and dynamically to environmental contingencies. From this claim flows a description of the elements theoretically needed to construct a virtual agent with the ability to display human-like emotions and to respond appropriately to human emotional expression. This article offers a brief survey of the desirable features of emotion theories that make them ideal blueprints for agent models. In particular, the component process model of emotion is described, a theory which postulates emotion-antecedent appraisal on different levels of processing that drive response system patterning predictions. In conclusion, investing seriously in emergent computational modelling of emotion using a nonlinear dynamic systems approach is suggested.

Full textAbstract:
This article examines the narrative and visual construct of the lowrider vehicle as part of the barrio aesthetic. The central argument is that the display of lowrider art can be better understood as an artistic community mechanism of resistance used to contest cultural exclusion from white art spaces. The principles of Gloria Anzaldúa’s borderlands theory provide exceptional insights into the analyses of aesthetic lowrider displays from the margins. We use this approach to theoretically frame lowriders’ artistic representations as a Chicana/o identity effort to build contemporary cultural spaces for themselves. This study employs a qualitative triangulation method that includes participant observations, photo documentation, and six semi-structured interviews. Between December 2006 and September 2007, data were collected from the cities of Lansing and South Haven as well as from two lowrider car shows in the state of Michigan. This study found that lowrider art works as a source of stability and structure for Chicana/o young adults who live on the margins of society. For young adults isolated from mainstream cultural spaces by the essentialist interpretations of art, the lowrider aesthetic represents an identity–resiliency component introduced through family and friends—consciously or unconsciously—to resist cultural oppression.

Full textAbstract:
The genotoxic and antigenotoxic behavior of the interfacial charge transfer (ICT) complex between nano-sized TiO2 particles and caffeic acid (CA) was studied in in vitro experiments. The formation of the ICT complex is indicated by the appearance of absorption in visible-spectral range. The continual variations method indicated bridging coordination between the ligand, caffeic acid, and the surface Ti atoms, while the stability constant of the ICT complex was found to be 1.5?103 mol-1 L. An agreement between the experimental data and the theoretical results, based on the density functional theory, was found. The ICT complex and its components did not display genotoxicity in the broad concentration range 0.4?8.0 mg mL-1 TiO2 at a mole ratio c(TiO2)/c(CA) = 8. On the other hand, post-treatment of damaged DNA by the ICT complex induced antigenotoxic effect at lower concentrations, but at higher concentrations, 5.125?10.250 mg mL-1 ICT, the ICT complex did not show any beneficial effect on H2O2-induced DNA damaged cells. The experimental data were analyzed using the combinatorial method to determine the effect of component interaction on the genotoxic and antigenotoxic behavior of the ICT complex.

We study the two-component Ginzburg–Landau (GL) theory, in the presence of a self-consistent vortex line, to obtain the penetration depth (λ) and the effective healing length (ξ), in the asymptotic limit r → ∞. All these parameters versus T/Tc are analyzed for the materials MgB 2, V 3 Si and LiFeAs in the interval 0.88 ≤ T/Tc ≤ 1.0, where the GL theory is assumed to be valid. We find that κ ≡ λ/ξ, which is another parameter not related to the GL parameter, is T-independent for V 3 Si and LiFeAs , while is T-dependent for the compound MgB 2. This result suggests that even though all these three materials display two-gap superconductivity overall, near Tc superconductivity in V 3 Si and LiFeAs seems to be different from the one in MgB 2. The use of this parameter, κ, as a new way to "study" the superconducting materials, under the presence of a single vortex, is valid for 0.88Tc≲ T ≤ Tc, namely, in the GL formalism.

Full textAbstract:
BackgroundQuality of maternal and newborn care is integral to positive clinical, social and psychological outcomes. Respectful care is an important component of this but is suboptimum in many low-income settings. A renewed energy among health professionals and academics is driving an international agenda to eradicate disrespectful health facility care around the globe. However, few studies have explored respectful care from different vantage points.MethodsWe used Strauss and Corbin’s grounded theory methodology to explore intrapartum experiences in Tanzania and Zambia. In-depth interviews were conducted with 98 participants (48 women, 18 partners, 21 health-providers and 11 key stakeholders), resulting in data saturation. Analysis involved constant comparison, comprising three stages of coding: open, axial and selective. The process involved application of memos, reflexivity and positionality.ResultsFindings demonstrated that direct and indirect social discrimination led to inequity of care. Health-providers were believed to display manipulative behaviours to orchestrate situations for their own or the woman’s benefit, and were often caring against the odds, in challenging environments. Emergent categories were related to the core category: respectful care, an added extra, which reflects the notion that women did not always expect or receive respectful care, and tolerated poor experiences to obtain services believed to benefit them or their babies. Respectful care was not seen as a component of good quality care, but a luxury that only some receive.ConclusionBoth quality of care and respectful care were valued but were not viewed as mutually inclusive. Good quality treatment (transactional care) was often juxtaposed with disrespectful care; with relational care having a lower status among women and healthcare providers. To readdress the balance, respectful care should be a predominant theme in training programmes, policies and audits. Women’s and health-provider voices are pivotal to the development of such interventions.

Full textAbstract:
1. The responses of single neurons in the inferior temporal cortex and the cortex in the banks of the anterior part of the superior temporal sulcus of three awake, behaving macaques were recorded during a visual fixation task. Stimulus images subtending 17 or 8.5 degrees were presented in the center of the display area, and fixation was either at the center of the display area, or at one of four positions that were on the stimulus, or several degrees off the edge of the test stimulus. The experiments were performed with face-selective cells, and the responses were compared for fixation at each position for both effective and noneffective face stimuli for each cell. 2. The firing rates of most neurons to an effective image did not significantly alter when visual fixation was as far eccentric as the edge of the face, and they showed only a small reduction when the fixation point was up to 4 degrees from the edge of the face. Moreover, stimulus selectivity across faces was maintained throughout this region of the visual field. 3. The centers of the receptive fields of the cells, as shown by the calculated "centers of gravity," were close to the fovea, with almost all being within 3 degrees of the fovea. 4. The receptive fields of the cells typically crossed the vertical midline for at least 5 degrees. 5. Information theory procedures were used to analyze the spike trains of the visual neurons. Nearly six times more information was carried by these neurons' firing rate about the identity of an image than about its position in the visual field. Thus the information theory analysis showed that the responses of these neurons reflected information about which stimulus had been seen in a relatively translation invariant way. 6. Principal component analysis showed that principal component 1 (PC1) is related primarily to firing rate and reflected information primarily about stimulus identity. (For identity PC2 added only 14% more information to that contained in PC1.) Principal component 2 (PC2) was more closely related to neuronal response latencies, which increased with increasing eccentricity of the image in the visual field. PC2 reflected information about the position of the stimulus in the visual field, in that PC2 added 109% more information to that contained in PC1 about the position of the stimulus in the visual field.(ABSTRACT TRUNCATED AT 400 WORDS)

Full textAbstract:
AbstractCosmopolitanism has been argued to be a crucial component of peacebuilding, both with regard to its aims as well as its staff. In a universalist-liberal understanding of the concept, cosmopolitanism is the optimal mind frame for peacebuilders to rebuild post-war societies, due to the tolerance, justice-orientation, and neutrality regarding local cleavages that the concept entails in theory. This article argues, however, that cosmopolitanism cannot be understood outside of its social context, therefore requiring sociological empirical analyses. Drawing on three such sociological concepts, namely elite, glocal, and localisable cosmopolitanism, the article analyses empirically through interviews with peacebuilders in Kosovo whether and in which form these international civil servants display cosmopolitan worldviews. The study concludes that while in theory the localisable variant would be best suited to contribute to locally sensitive, emancipatory peacebuilding, this form of cosmopolitanism is absent in practice. Given the novel, exploratory character of this analysis of hitherto uncharted terrain, the article also discusses in detail how the findings were obtained and in how far they are generalisable.

Full textAbstract:
The Aharonov–Bohm electrodynamics is a generalization of Maxwell theory with reduced gauge invariance. It allows to couple the electromagnetic field to a charge which is not locally conserved, and has an additional degree of freedom, the scalar field [Formula: see text], usually interpreted as a longitudinal wave component. By reformulating the theory in a compact Lagrangian formalism, we are able to eliminate S explicitly from the dynamics and we obtain generalized Maxwell equation with interesting properties: they give [Formula: see text] as the (conserved) sum of the (possibly non-conserved) physical current density [Formula: see text], and a “secondary” current density [Formula: see text] which is a nonlocal function of [Formula: see text]. This implies that any non-conservation of [Formula: see text] is effectively “censored” by the observable field [Formula: see text], and yet it may have real physical consequences. We give examples of stationary solutions which display these properties. Possible applications are to systems where local charge conservation is violated due to anomalies of the Adler–Bell–Jackiw (ABJ) kind or to macroscopic quantum tunnelling with currents which do not satisfy a local continuity equation.

Full textAbstract:
Abstract. A theoretical model is proposed to account for some of the behavior of arc-polarized magnetic structures seen in the solar wind. To this end, an exact analytical solution is developed that describes infinite plane wave trains of arbitrary amplitude in a plasma governed by ideal Hall MHD. The main focus is on intermediate-mode wave trains, which display double-branched magnetic hodogram signatures similar to those seen in the solar wind. The theoretically derived hodograms have field rotation in the ion-polarized sense at a slightly depressed field magnitude on one branch and an electron-polarized rotation at a slightly enhanced field magnitude on the other branch. The two branches are joined at the two "turning points", at which the normal flow is exactly Alfvénic. The behavior is accounted for in terms of the opposite dispersive properties of ion and electron whistlers. The hodograms derived from the theory are shown to compare favorably with those of one event, observed by the Cluster spacecraft near the ecliptic plane, and one event at high heliographic latitude observed by the Ulysses spacecraft. However, these two observed structures comprise only a single full wave period, approximately from one turning point to the other and then back again. The theory can be used to predict propagation direction (away from, or towards, the sun) from magnetic data alone, provided the sign of the magnetic field component along the wave normal can be reliably determined. Under the same condition, it also predicts whether the ion-polarized branch should precede or follow the electron-polarized branch. Both behaviors are seen in the solar wind. The major shortcoming of the theory is that it fails to reproduce the observed saw-tooth like time series for the magnetic field, in which the field rotation is rapid in the ion sense and slow in the electron sense. Instead, the theory gives about the same rotation rates. Possible explanations for this discrepancy are discussed. Also discussed is the fact that the magnetic field measurements by Cluster, while giving high quality determinations of normal direction and normal field component for each of the four spacecraft, indicate a reversal of the normal field component and the predicted propagation sense during the event, as well as a wide spread in the four normal vector orientations.

This paper describes an innovative and sophisticated approach for improving learner-computer interaction in the tutoring of Java programming through the delivery of adequate learning material to learners. To achieve this, an instructional theory and intelligent techniques are combined, namely the Component Display Theory along with content-based filtering and multiple-criteria decision analysis, with the intention of providing personalized learning material and thus, improving student interaction. Until now, the majority of the research efforts mainly focus on adapting the presentation of learning material based on students’ characteristics. As such, there is free space for researching issues like delivering the appropriate type of learning material, in order to maintain the pedagogical affordance of the educational software. The blending of instructional design theories and sophisticated techniques can offer a more personalized and adaptive learning experience to learners of computer programming. The paper presents a fully operating intelligent educational software. It merges pedagogical and technological approaches for sophisticated learning material delivery to students. Moreover, it was used by undergraduate university students to learn Java programming for a semester during the COVID-19 lockdown. The findings of the evaluation showed that the presented way for delivering the Java learning material surpassed other approaches incorporating merely instructional models or intelligent tools, in terms of satisfaction and knowledge acquisition.

This paper reviews the developments that have occurred in the field of human genetics of infectious diseases from the second half of the 20th century onward. In particular, it stresses and explains the importance of the recently described monogenic inborn errors of immunity underlying resistance or susceptibility to specific infections. The monogenic component of the genetic theory provides a plausible explanation for the occurrence of severe infectious diseases during primary infection. Over the last 20 y, increasing numbers of life-threatening infectious diseases striking otherwise healthy children, adolescents, and even young adults have been attributed to single-gene inborn errors of immunity. These studies were inspired by seminal but neglected findings in plant and animal infections. Infectious diseases typically manifest as sporadic traits because human genotypes often display incomplete penetrance (most genetically predisposed individuals remain healthy) and variable expressivity (different infections can be allelic at the same locus). Infectious diseases of childhood, once thought to be archetypal environmental diseases, actually may be among the most genetically determined conditions of mankind. This nascent and testable notion has interesting medical and biological implications.

Abstract Sea surface height anomalies measured by the Ocean Topography Experiment (TOPEX)/Poseidon satellite altimeter indicate high values of skewness and kurtosis. Except in a few regions, including the Gulf Stream, the Kuroshio Extension, and the Agulhas Retroflection, that display bimodal patterns of sea surface height variability, kurtosis is uniformly greater than 1.5 times the squared skewness minus an adjustment constant. This relationship differs substantially from what standard Gaussian or double-exponential noise would produce. However, it can be explained by a simple theory in which the noise is assumed to be multiplicative, meaning that a larger background state implies larger random noise elements. The existence of multiplicative noise can be anticipated from the equations of motion, if ocean dynamics are split into a slowly decorrelating deterministic component and a rapidly decorrelating contribution that is approximated as noise. Such a model raises the possibility of predicting the probabilities of extreme sea surface height anomalies from first physical principles and may provide a useful null hypothesis for non-Gaussian sea surface height variability.

Full textAbstract:
ABSTRACT For obligately lytic bacteriophage (phage) a trade-off exists between fecundity (burst size) and latent period (a component of generation time). This trade-off occurs because release of phage progeny from infected bacteria coincides with destruction of the machinery necessary to produce more phage progeny. Here we employ phage mutants to explore issues of phage latent-period evolution as a function of the density of phage-susceptible bacteria. Theory suggests that higher bacterial densities should select for shorter phage latent periods. Consistently, we have found that higher host densities (≥∼107 bacteria/ml) can enrich stocks of phage RB69 for variants that display shorter latent periods than the wild type. One such variant, dubbed sta5, displays a latent period that is ∼70 to 80% of that of the wild type—which is nearly as short as the RB69 eclipse period—and which has a corresponding burst size that is ∼30% of that of the wild type. We show that at higher host densities (≥∼107 bacteria/ml) the sta5 phage can outcompete the RB69 wild type, though only under conditions of direct (same-culture) competition. We interpret this advantage as corresponding to slightly faster sta5 population growth, resulting in multifold increases in mutant frequency during same-culture growth. The sta5 advantage is lost, however, given indirect (different-culture) competition between the wild type and mutant or given same-culture competition but at lower densities of phage-susceptible bacteria (≤∼106 bacteria/ml). From these observations we suggest that phage displaying very short latent periods may be viewed as specialists for propagation when bacteria within cultures are highly prevalent and transmission between cultures is easily accomplished.

Financial bubbles are a result of aggregate irrational behavior and cannot be explained by standard economic pricing theory. Research in neuroeconomics can improve our understanding of their causes. We conducted an experiment in which 28 healthy subjects traded in a simulated market bubble, while scalp EEG was recorded using a low-cost, BCI-friendly desktop device with 14 electrodes. Independent component (IC) analysis was performed to decompose brain signals and the obtained scalp topography was used to cluster the ICs. We computed single-trial time-frequency power relative to the onset of stock price display and estimated the correlation between EEG power and stock price across trials using a general linear model. We found that delta band (1–4 Hz) EEG power within the left frontal region negatively correlated with the trial-by-trial stock prices including the financial bubble. We interpreted the result as stimulus-preceding negativity (SPN) occurring as a dis-inhibition of the resting state network. We conclude that the combination between the desktop-BCI-friendly EEG, the simulated financial bubble and advanced signal processing and statistical approaches could successfully identify the neural correlate of the financial bubble. We add to the neuroeconomics literature a complementary EEG neurometric as a bubble predictor, which can further be explored in future decision-making experiments.

Luminescent cuprous complexes are important coordination compounds due to their relative abundance, low cost and ability to display excellent luminescence. The structures of two CuIP2S-type cuprous complexes, namely, iodido(thiourea-κS)bis(triphenylphosphane-κP)copper(I), [CuI(CH4N2S)(C18H15P)2] or [CuI(TU)(TPP)2] (I), and (2,3-dihydrobenzimidazole-2-thione-κS)iodidobis(triphenylphosphane-κP)copper(I), [CuI(C7H6N2S)(C18H15P)2] or [CuI(DHBIT)(TPP)2] (II), are described. In these two structures, the complex molecules of both are constructed by one copper(I) centre, one iodide ion, two TPP ligands and one thione ligand (TU for I and DHBIT for II). The copper(I) centres of I and II are both located in a distorted CuIP2S tetrahedron and are coordinated by two P atoms from two TPP ligands, one S atom from the thione ligand and the I atom. The UV–Vis absorption and photoluminescence properties of these CuIP2S-type cuprous complexes have been studied using crystalline powder samples. Detailed time-dependent density functional theory (TD-DFT) calculations and wavefunction analysis reveal that the pale-blue–green phosphorescence emission should originate from intra-ligand (TPP for I and DHBIT for II) charge transfer, with a small component of the metal-to-ligand charge transfer 3(IL+ML)CT excited state.

While design theories in visual displays have been well developed and further refined, relatively little research has been conducted on design theories and models in auditory displays. The existing discussions mainly account for functional mappings between sounds and referents, but these do not fully address design aspects of auditory displays. To bridge the gap, the present proposal focuses on design affordances in sound design among many design constructs. To this end, the definition and components of design affordances are briefly explored, followed by the auditory display examples of those components to gauge whether sound can deliver perceived affordances in interactive products. Finally, other design constructs, such as feedback and signifier, are discussed together with future work. This exploratory proposal is expected to contribute to elaborating sound design theory and practice.

Color image is often considered as a fundamental perceptual unit of visualization. In this paper, we suggest using this medium (color image) to summarize multidimensional data and thus to turn a data set into a meaningful insight. The methodology we use is based on the theory of Keim for designing pixel-oriented visualization techniques. The technique we propose consists in a three-step pipeline. The first one is devoted to dimensionality reduction by projecting multidimensional data into a three-dimensional space. In this work, we use the classical principal component analysis (PCA) to reduce the dimension to three. The second step, called color mapping, is based on the reverse color information transformation defined by Ohta et al. This stage is the main novelty of this work in addition to the pipeline itself. The third step consists in a pixel-oriented method to display large data sets with an image using space-filling curve techniques. The combination of these steps (first, dimensionality reduction with PCA, second, color mapping with color information of Ohta et al., and third, space-filling curve with Peano–Hilbert curve) allows us to obtain a new unsupervised visualization technique through color images. This blind (i.e. unsupervised) technique using a color image gives a previsualization that can be used before exploring the data set or choosing more effective colors. Some applications are proposed in the field of multicomponent image visualization.

Complex networks in reality may suffer from target attacks which can trigger the breakdown of the entire network. It is therefore pivotal to evaluate the extent to which a network could withstand perturbations. The research on network robustness has proven as a potent instrument towards that purpose. The last two decades have witnessed the enthusiasm on the studies of network robustness. However, existing studies on network robustness mainly focus on multilayer networks while little attention is paid to multipartite networks which are an indispensable part of complex networks. In this study, we investigate the robustness of multipartite networks under intentional node attacks. We develop two network models based on the largest connected component theory to depict the cascading failures on multipartite networks under target attacks. We then investigate the robustness of computer-generated multipartite networks with respect to eight node centrality metrics. We discover that the robustness of multipartite networks could display either discontinuous or continuous phase transitions. Interestingly, we discover that larger number of partite sets of a multipartite network could increase its robustness which is opposite to the phenomenon observed on multilayer networks. Our findings shed new lights on the robust structure design of complex systems. We finally present useful discussions on the applications of existing percolation theories that are well studied for network robustness analysis to multipartite networks. We show that existing percolation theories are not amenable to multipartite networks. Percolation on multipartite networks still deserves in-depth efforts.

This study sought to: (1) analytically separate the components of a graphical display which contributed to performance on integrated and separable tasks; and (2) determine the effect of the number of dimensions of information which had to be integrated. To that end, the study employed a 7 × 3 mixed design with seven displays manipulated between-subjects and the number of information dimensions (three, six, and nine) manipulated within-subjects. The seven displays examined included two bar graphs (non-object and object formats), two midline displays (non-object and object formats), a direct graphical display, and two numerical displays (numerical separable and numerical integrative). Based upon propositions generated from emergent feature theory, the ability to integrate information in these displays should be a function of the faithfulness, saliency, and directness of mapping the decision statistic onto the display. Results indicated that the displays which directly represented the integrated decision, the numerical integrative and the direct graphical displays, resulted in the best performance. Intermediate performance was obtained on those displays (i.e. the object bar graph, the non-object midline, and the object midline) which incorporated faithfulness, saliency, or both, respectively. The worst performance on the integrated task was exhibited for those displays (i.e. the numerical separable and the non-object bar) which did not represent directness, faithfulness, or saliency. For both the integrated and separable tasks, accuracy increased as the number of information dimensions increased. The unexpected direction of this effect was attributed to subjects” investing more resources in performing the task at the six or nine cue levels due to the perceived increase in difficulty of the task.

Full textAbstract:
Anti-predator defences are typically regarded as relatively static signals that conceal prey or advertise their unprofitability. However, startle displays are complex performances that deter or confuse predators and can include a spectacular array of movements, colours and sounds. Yet, we do not fully understand the mechanisms by which they function, their evolutionary correlates, or the conditions under which they are performed and evolve. Here, we present, to our knowledge, the first phylogenetically controlled comparative analyses of startle displays including behavioural data, using praying mantises as a model system. We included 58 species that provide a good representation of mantis diversity and estimated the strength of phylogenetic signal in the presence and complexity of displays. We also tested hypotheses on potential evolutionary correlates, including primary defences and body size. We found that startle displays and morphological traits were phylogenetically conserved, whereas behavioural traits were highly labile. Surprisingly, body size was not correlated with display presence or complexity in phylogenetically controlled analyses. Species-rich clades were more likely to exhibit displays, suggesting that startle displays were probably involved in lineage diversification. We suggest that to further elucidate the conditions under which startle displays evolve, future work should include quantitative descriptions of multiple display components, habitat type, and predator communities. Understanding the evolution of startle displays is critical to our overall understanding of the theory behind predator–prey dynamics.

Abstract This article is part of a body of research into the conventions which govern the composition of Gothic texts. Gothic fiction resorts to formulas or formula-like constructions, but whereas in writers such as Ann Radcliffe this practice is apt to be masked by stylistic devices, it enjoys a more naked display in the–in our modern eyes–less ‘canonical’ Gothics, and it is in these that we may profitably begin an analysis. The novel selected was Peter Teuthold’s The Necromancer (1794)–a very free translation of K. F. Kahlert’s Der Geisterbanner (1792) and one of the seven Gothic novels mentioned in Jane Austen’s Northanger Abbey. There is currently no literature on the topic of formulaic language in Gothic prose fiction. The article resorts to a modified understanding of the term ‘collocation’ as used in lexicography and corpus linguistics to identify the significant co-occurrence of two or more words in proximity. It also draws on insights from the Theory of Oral-Formulaic Composition, in particular as concerns the use of the term ‘formula’ in traditional epic poetry, though again some modifications are required by the nature of Teuthold’s text. The article differentiates between formula as a set of words which appear in invariant or near-invariant collocation more than once, and a formulaic pattern, a rather more complex, open system of collocations involving lexical and other fields. The article isolates a formulaic pattern—that gravitating around the node-word ‘horror’, a key word for the entire Gothic genre –, defines its component elements and structure within the book, and analyses its thematic importance. Key to this analysis are the concepts of overpatterning, ritualization, equivalence and visibility.
