Re‐shaping hysteretic behaviour—spectral analysis and design equations for semi‐active structures

Semi-active dampers offer significant capability to reduce dynamic wind and seismic structural response. A novel resetable device with independent valve control laws that enables semi-active re-shaping of the overall structural hysteretic behaviour has been recently developed, and a onefifth scale prototype experimentally validated. This research statistically analyses three methods of re-shaping structural hysteretic dynamics in a performance-based seismic design context. Displacement, structural force, and total base-shear response reduction factor spectra are obtained for suites of ground motions from the SAC project. Results indicate that the reduction factors are suite invariant. Resisting all motion adds damping in all four quadrants and showed 40-60% reductions in the structural force and displacement at the cost of a 20-60% increase in total base-shear. Resisting only motion away from equilibrium adds damping in quadrants 1 and 3, and provides reductions of 20-40%, with a 20-50% increase in total base-shear. However, only resisting motion towards equilibrium adds damping in quadrants 2 and 4 only, for which the structural responses and total base-shear are reduced 20-40%. The spectral analysis results are used to create empirical reduction factor equations suitable for use in performance based design methods, creating an avenue for designing these devices into structural applications. Overall, the reductions in both response and base-shear indicate the potential appeal of this semi-active 1Dept. of Mechanical Engineering, University of Canterbury, Christchurch, New Zealand 2Dept of Civil Engineering, University of Canterbury, Christchurch, New Zealand 2 hysteresis sculpting approach for seismic retrofit applications — largely due to the reduction of the structural force and overturning demands on the foundation system.
Anthraquinonedisulfonate adsorption, electron-transfer kinetics, and capacitance on ordered graphite electrodes: the important role of surface defects

The adsorption of anthraquinone-2,6-disulfonate, disodium salt (AQDS), was found to be well behaved at glassy carbon (GC) and highly oriented pyrolytic graphite (HOPG) electrodes. On laser-activated GC, the surface excess obeys a Langmuirian isotherm in the concentration range of 5×10 -8 to 1×10 -5 M with a saturation coverage of 228 pmol/cm 2 . AQDS at untreated HOPG electrodes was studied more extensively
Attention to Indications to Embedded Ideologies in Discourse across Translation Educational Levels and Gender

In a world with a complex and multifaceted socio-political agenda, translators as intercultural mediators need to be equipped with a critical eye for implicit ideologies in linguistic and symbolic discourses which are the main instrumentation in shaping and reshaping mental and cognitive frameworks of the public through which they conceive of the world and act accordingly. In the context of Iranian translator education, the study investigates the effeteness of educational levels in addition to gender on the attentiveness and priorities of prospective English translators as for exploring various levels which are apt to accommodate power relations and ideological representations in socio-political discourse in translation. The study uses an empirically validated questionnaire instrument (Khoshsaligheh, 2012) which draws on ideological square and ideological discourse structures advocated by van Dijk (1998, 2000, 2009). Using inferential statistics, the analysis of the data indicates that the educational exposure currently is not an effective variable for improving the attentiveness of prospective English translators, and neither is the variable of gender.
The Cross-Sectional Profitability of a Moving Average Timing Strategy on Factor Investing

This paper investigates the cross-sectional performance of a moving average timing strategy on portfolios formed on the volatility and momentum anomaly. Building on past research, the results show that a moving average timing strategy with relative shorter lags is able to significantly increase the performance of particularly the higher volatility portfolios. Furthermore, similar results are obtained when using the moving average timing strategy on portfolios sorted on momentum. The highest significant increase in performance is found in the losers’ portfolio with a 20-day lag moving average.
Manipulating territory size via vegetation structure: optimal size of area guarded by the convict cichlid (Pisces, Cichlidae)

To test the predictions of optimal territory size models, we attempted to manipulate the size of area that a dominant convict cichlid fish (Archocentrus nigrofasciatus) would defend around a food patch by placing simulated vegetation at three different distances from the edge of the patch (0, 11, and 22 cm). As expected, the size of area defended against four smaller intruders increased as the vegetation was moved farther from the patch. Consistent with optimal territory size models, both the costs of defence, measured as chase radius and chase rate, and the benefits of defence, measured as the amount of food eaten by the defender, increased with the distance of the vegetation from the patch. Growth rates of the defenders, however, did not differ among the treatments, perhaps because the benefits of monopolizing food were balanced by the costs of defending a larger area. Our data support the hypothesis that the size of a guarded area around an ephemeral resource patch affects both the costs and benefits of defence.
Discovery potential for the neutral charmoniumlike Z 0 ( 4200 ) by p̄p annihilation

Inspired by the observation of charmoniumlike Z(4200), we explore the discovery potential of the neutral Z(4200) production by antiproton-proton annihilation with an effective Lagrangian approach. By investigating the p̄p→ J/ψπ process including the Z(4200) signal and background contributions, it is found that the center of mass energy Ec.m. ≃ 4.0 − 4.5 GeV is the best energy window for searching the neutral Z(4200), where the signal can be clearly distinguished from background. The relevant calculations is not only helpful to search for the neutral Z(4200) in the future experiment, but also will promote the understanding the nature and production mechanism of neutral Z(4200) better.
Exogen markers of human embryo quality in culture medium

In assisted reproduction technology embryo competence is routinely evaluated on morphological criteria that only to some extent have developmental significance. Over the last decade, novel approaches including genomics, transcriptomics, proteomics and metabolomics have been investigated. In this context, several efforts in improving embryo quality assessment have looked for exogen markers in the embryo culture medium. These embryo selection methods are based on analysis of spent culture medium nutrient and metabolite content, and analytical examination of embryonic metabolome and secretome. More recently, some Authors looked at cell-free nucleic acids as non-invasive biomarkers of embryo competence. Taking into consideration that for clinical application the ideal embryo quality assessment method should be non-invasive, reproducible, objective, rapid, easy to use routinely, and cost-effective, to date few of the novel technologies have the potential to be implemented as standard selection procedures in the IVF labs. Undoubtedly an improvement over the current embryo assessment strategies is needed and it is desirable that emerging exogen markers could help embryologists in choosing which embryos to transfer. For this purpose, the true clinical predictive value of putative exogen markers has to be prospectively validated to implement current morphologybased selection methods.
Reaction textures and fluid behaviour in very high pressure calc-silicate rocks of the Münchberg gneiss complex, Bavaria, Germany

Calc-silicate rocks occur as elliptical bands and boudins intimately interlayered with eclogites and high-pressure gneisses in the Munchberg gneiss complex of NE Bavaria. Core assemblages of the boudins consist of grossular-ric h garnet, diopside, quartz, zoisite, clinozoisite, calcite, rutile and titanite. The polygonal granoblastic texture commonly displays mineral relics and reaction textures such as post- kinematic grossular-rich garnet coronas. Reactions between these mineral phases have been modelled in the CaO-Al 2 0 3 -Si02-C 02-H 20 system with an internally consistent thermodynamic data base. High-pressure metamorphism in the calc-silicate rocks has been estimated at a minimum pressure of 31 kbar at a temperature of 630°C with X^oSQ.Gi. Small volumes of a C02-N2-rich fluid whose composition was buffered on a local scale were present at peak-metamorp hic conditions. The P-T conditions for the onset of the amphibolite facies overprint are about 10 kbar at the same temperature. A'co., of the H20-rich fluid phase is regarded to have been <0.03 during amphibolite facies conditions. These P-T estimates are interpreted as representing different stages of recrystalliza tion during isothermal decompression. The presence of multiple generations of mineral phases and the preservation of very high-pressure relics in single thin sections preclude pervasive post-peak metamorphic fluid flow as a cause of a re-equilibration within the calc-silicates. The preservation of eclogite facies, very high-pressure relics as well as amphibolite facies reactions textures in the presence of a fluid phase is in agreement with fast, tectonically driven unroofing of these rocks.
Using Students' Sketches to Recognize Alternative Conceptions About Plate Tectonics Persisting From Prior Instruction

ABSTRACT Should instructors assume that students possess conceptual knowledge of plate tectonics when they reach a second college geoscience course? Five cohorts in a historical geology course over 5 y—a total of 149 students—completed an in-class assignment in which they drew sketches of plate boundaries with required annotations. Analysis of the sketches revealed that most students lack an explanatory mental model that links the locations of earthquakes, volcanoes, and magma generation to plate-boundary processes and hold a pervasive alternative conception of Earth's interior structure that does not distinguish between compositional and rheological boundaries. Students who drew sketches that illustrated the most alternative conceptions also scored lower on a beginning-of-the-course administration of the Geoscience Concept Inventory, showing that conceptual understanding of plate tectonics correlates with overall conceptual geoscience knowledge obtained during previous course experiences. In addition, students tracking to the historical geology course via an introductory physical geology course showed stronger conceptual understanding of plate tectonics than those choosing an Earth-system science prerequisite, with those students previously enrolled in both courses illustrating the fewest alternative conceptions.
Linking Risk Management to Strategic Controls: A Case Study of Tesco Plc

Definitions and perceptions of the role and styles of risk management, and performance management/strategic control systems have evolved over time, but it can be argued that risk management is primarily concerned with ensuring the achievement of strategic objectives. This paper shows the extent of overlap between a broad-based view of risk management, namely Enterprise Risk Management (ERM), and the balanced scorecard, which is a widely used strategic control system. A case study of one of the UK's largest retailers, Tesco plc, is used to show how ERM can be introduced as part of an existing strategic control system. The case demonstrates that, despite some differences in lines of communications, the strategic controls and risk controls can be used to achieve a common objective. Adoption of such an integrated approach, however, has implications for the profile of risk and the overall risk culture within an organisation.
INOCULATION WITH ACC-DEAMINASE CONTAINING RHIZOBACTERIA FOR IMPROVING GROWTH AND YIELD OF WHEAT

Six strains (Qso, N3, Q7, N7, Q14 & Y) of plant growth promoting rhizobacteria showing ACC-deaminase activity were isolated from rhizosphere of wheat. Wheat seeds were inoculated and sown in pots filled with 12 kg soil fertilized with NPK @ 150-120-70 kg na', respectively. All the isolates exhibited a significant increase in grain yield, straw yield, root weight, root elongation, number of tillers, N, P & K uptake in straw and grain over uninoculated control. Root elongation, root weight, straw yield and grain yield increased up to 31, 83, 69 and 60%, respectively, over un inoculated control. The growth promoting activity exhibited by the rhizobacteria might be due to their ability to hydrolyze ACC, thus resulting in decreased endogenous ethylene synthesis, which eliminated the potential inhibitory effects of higher ethylene concentrations. Results showed that ACC-deaminase containing plant growth promoting rhizobacteria could be effectively used for growth promotion in wheat.
Combining WASP and Kepler data: the case of the δ Sct star KIC 7106205

Ground-based photometric observations from Wide Angle Search for Planets (WASP) have been calibrated, scaled and combined with Kepler observations of the δ Sct star KIC 7106205, allowing us to extend the time base of the study of the unexplained amplitude and frequency variation of a single pressure mode at ν = 13.3942 d−1 by 2 yr. Analysis of the combined data sets, spanning 6 yr, show that the amplitude modulation in KIC 7106205 has a much larger range than a previous study of the Kepler data alone indicated. The single pressure mode decreased from 11.70 ± 0.05 mmag in 2007, to 5.87 ± 0.03 mmag in 2009, and to 0.58 ± 0.06 mmag in 2013. Observations of the decrease in mode amplitude have now been extended back 2 yr before the launch of Kepler. With observations over a longer time span, we have been able to further investigate the decrease in mode amplitude in KIC 7106205 to address the question of mode amplitude stability in δ Sct stars. This study highlights the usefulness of the WASP data set for extending studies of some Kepler variable stars.
Workplace Employee Representation in Europe

For many in Europe, effective dialogue between employers and workers is seen as an important means of achieving the twin goals of social cohesion and economic growth. Using a recent workplace survey we explore the substantial variance in the incidence and nature of workplace employee representation across the European Union. Country dummies account for roughly one-fifth of all the variance in workplace representation. Its incidence is strongly and independently correlated with the degree of centralization in industrial relations regimes, public confidence in worker representation and the extent of legislative support for it. We also find evidence supportive of the exit-voice model traditionally associated with AngloSaxon regimes whereby worker representation is associated with poorer perceptions of the employment relations climate and with lower voluntary quit rates. However, these findings on the effects of worker representation are only statistically significant where representation has a dual-channel format, combining both trade union and works council representation.

On the effect of pluralization on the numeralization of nouns in English and Polish: a contrastive corpus-based study

N2-collocates in purely quantifi cational uses, in an attempt to establish whether, and to what extent, the addition of the plurality morpheme bears on the grammaticalization of a nominal of this kind into an indefi nite quantifi er. Following the observations arrived at by Brems (2003, 2011), the hypothesis is that pluralization should yield a facilitating effect on the numeralization of nouns referring to large quantities by amplifying their inherent scalar implications. The results demonstrate that whereas heaps indeed exhibits a higher percentage of such numeralized uses than heap, kupy ‘heaps’ has turned out to be grammaticalized in the quantifying function to a markedly lesser degree than kupa ‘heap’. It is argued that this apparently aberrant behaviour of kupy ‘heaps’ can nonetheless be elucidated in terms of the specifi city of numeralization in Polish, since at its advanced, morphosyntactic stage, the process in question affects solely the singular (accusative) forms of QNs.
Exploring the Research Trends-Related Imbalances in Doctoral Level Research on Distance Education in Pakistan

The areas of research and methodological dimensions in the distance education are expanding rapidly due to technological advances (Wong et al., 2016). This research intends to investigate the imbalances in domains of research topics and methodological dimensions in the doctoral level dissertations at Allama Iqbal Open University (AIOU) between 20012014. The 37 PhD dissertations accessed from the Higher Education Commission (HEC)’s research repository were selected as the sample of this study, which were reviewed to record the research topics, research types/models, data collection tools and data analysis instruments and categories of the participants. The results of this study revealed imbalanced approach of PhD researchers towards addressing the research areas in distance education and research methodological considerations used to tackle the research issues in doctoral level dissertations at AIOU. The outcomes of this study contribute to the existing literature on the research trends of distance education, in addition to informing the academics, AIOU-based supervisors and HEC-based policy-makers to address the imbalanced approach to achieve the comprehensive picture of the research issues in distance education. This is critical for successful promotion and implementation of distance education and prioritization of research areas in Pakistani distance education sector.
Heliconia acuminata reproductive success is independent of local floral density

Reproductive plants in tropical forests are patchily distributed, with some in large aggregations of reproductive consepecifics while others are relatively isolated. This variation in floral density is hypothesized to have a major effect on plant reproductive success, since individuals in higher density neighborhoods can attract more or higher quality pollinators. We experimentally tested this hypothesis with populations of the understory herb Heliconia acuminata in central Amazonia. We created replicated plots in which reproductive plant density spanned the range of naturally occurring floral neighborhood size, then measured three surrogates of plant fitness in focal plants in each array. There was no significant difference between any of the three floral neighborhood treatments in total seed production, fruit set, or the number of seeds produced per fruit. Pollinator visitation rates to plants in all treatments were extremely low, with many plants not visited at all during the observation period. This could be because H. acuminata's hummingbird pollinators are unable to find the widely scattered reproductive plants, however this hypothesis appears unlikely. Instead, natural flowering plant densities may simply be below the threshold value at which neighborhood effects become important, even in "high-density" aggregations. Nutrient limitation, selective fruit abortion, and reproduction via male rather than female function may also be playing a role. We argue the absence of neighborhood effects may be a general phenomenon in central Amazonian forests, though additional experiments with other plant-pollinator systems are needed to determine the extent to which this hypothesis is supported.
ON GEOMETRIC PROCESSING OF MULTI-TEMPORAL IMAGE DATA COLLECTED BY LIGHT UAV SYSTEMS

Abstract. Data collection under highly variable weather and illumination conditions around the year will be necessary in many applications of UAV imaging systems. This is a new feature in rigorous photogrammetric and remote sensing processing. We studied performance of two georeferencing and point cloud generation approaches using image data sets collected in four seasons (winter, spring, summer and autumn) and under different imaging conditions (sunny, cloudy, different solar elevations). We used light, quadrocopter UAVs equipped with consumer cameras. In general, matching of image blocks collected with high overlaps provided high quality point clouds. All of the before mentioned factors influenced the point cloud quality. In winter time, the point cloud generation failed on uniform snow surfaces in many situations, and during leaf-off season the point cloud generation was not successful over deciduous trees. The images collected under cloudy conditions provided better point clouds than the images collected in sunny weather in shadowed regions and of tree surfaces. On homogeneous surfaces (e.g. asphalt) the images collected under sunny conditions outperformed cloudy data. The tested factors did not influence the general block adjustment results. The radiometric sensor performance (especially signal-to-noise ratio) is a critical factor in all weather data collection and point cloud generation; at the moment, high quality, light weight imaging sensors are still largely missing; sensitivity to wind is another potential limitation. There lies a great potential in low flying, low cost UAVs especially in applications requiring rapid aerial imaging for frequent monitoring.
Types of Aggression, Responsiveness to Provocation, and Psychopathic Traits

Research on the various subtypes of aggression has documented differences in the experience of anger and the expression of angry aggression. Mixed proactive and reactive aggressive individuals exhibit reactive aggression but, unlike reactive aggressive individuals, fail to exhibit angry expressions or physiological arousal. Similar to the proactive group, individuals with psychopathic traits have been found to exhibit emotional underreactivity, and physiological underarousal, while still exhibiting reactive aggression. The present study examined 85 boys (ages 13 to 18) from a detention center. Three groups of aggressive boys were identified via cluster analysis based on the self-report of types of aggressive behavior: a primarily reactive aggressive group (n=29), a mixed reactive and proactive group (n=16), and a low aggressive group (n=40). The three groups were compared on aggressive responding (during a computerized provocation task with low and high provocation trials), on callous and unemotional traits (CU) and on psychophysiological indices of emotional reactivity. All aggressive groups showed greater aggressive responding to high provocation than to low provocation. The mixed aggressive group showed high aggressive responding across all provocation levels, including the no provocation condition, while the reactive aggressive group only showed high levels similar to the mixed aggressive group during low provocation. Unexpectedly, the reactive and mixed aggressive groups reported higher levels of CU traits than the other group. Although the groups did not differ on psychophysiological activity/reactivity, higher levels of CU traits were related to lower skin conductance responses to provocation. Thus, the contribution of high and low CU traits in the three groups to psychophysiological activity/reactivity was examined. Interestingly, the low and mixed aggressive groups who were high on CU traits had lower sympathetic arousal (indexed by skin conductance) and lower sympathetic reactivity to provocation. Thus, the mixed
