description: In the epoch of precise and accurate cosmology, cross-confirmation using a variety of cosmographic methods is paramount to circumvent systematic uncertainties. Owing to progenitor histories and explosion physics differing from those of Type Ia SNe (SNe Ia), Type II-plateau supernovae (SNe II-P) are unlikely to be affected by evolution in the same way. Based on a new analysis of 17 SNe II-P, and on an improved methodology, we find that SNe II-P are good standardizable candles, almost comparable to SNe Ia. We derive a tight Hubble diagram with a dispersion of 10% in distance, using the simple correlation between luminosity and photospheric velocity introduced by Hamuy & Pinto 2002. We show that the descendent method of Nugent et al. 2006 can be further simplified and that the correction for dust extinction has low statistical impact. We find that our SN sample favors, on average, a very steep dust law with total to selective extinction R_V<2. Such an extinction law has been recently inferred for many SNe Ia. Our results indicate that a distance measurement can be obtained with a single spectrum of a SN II-P during the plateau phase combined with sparse photometric measurements.

description: Abstract

Mangrove forests have high carbon storage capacity and potential in climate change mitigation efforts. This study aimed to analyze the species composition, stand structure, biomass, carbon storage, and carbon dioxide absorption of mangrove stands in the Pantai Indah Kapuk (PIK) Mangrove Ecotourism Area, DKI Jakarta. This research method uses stratified random sampling and calculates the number of observation plots using the Slovin formula. Biomass estimation was carried out using the allometric equations. From the results of vegetation analysis, there are ten species of mangroves, namely Rhizophora mucronata, Avicennia marina, Sonneratia caseolaris, Excoecaria agallocha, Cerbera manghas, Terminalia catappa, Rhizophora apiculata, Calophyllum inophyllum, Morinda citrifolia, and Nypa fruticans. Total biomass, carbon storage, and carbon dioxide absorption by mangroves in the study area are 253, 18 tons ha-1, 119 tons ha-1, and 436, 71 tons ha-1, respectively. Environmental factors influence the value of carbon storage and carbon dioxide absorption by mangroves in the planting area.

description: Our objective is to stabilise and accelerate the time-domain boundary element method (TDBEM) for the three-dimensional wave equation. To overcome the potential time instability, we considered using the Burton--Miller-type boundary integral equation (BMBIE) instead of the ordinary boundary integral equation (OBIE), which consists of the single- and double-layer potentials. In addition, we introduced a smooth temporal basis, i.e. the B-spline temporal basis of order $d$, whereas $d=1$ was used together with the OBIE in a previous study [Takahashi 2014]. Corresponding to these new techniques, we generalised the interpolation-based fast multipole method that was developed in \cite{takahashi2014}. In particular, we constructed the multipole-to-local formula (M2L) so that even for $d\ge 2$ we can maintain the computational complexity of the entire algorithm, i.e. $O(N_{\rm s}^{1+δ} N_{\rm t})$, where $N_{\rm s}$ and $N_{\rm t}$ denote the number of boundary elements and the number of time steps, respectively, and $δ$ is theoretically estimated as $1/3$ or $1/2$. The numerical examples indicated that the BMBIE is indispensable for solving the homogeneous Dirichlet problem, but the order $d$ cannot exceed 1 owing to the doubtful cancellation of significant digits when calculating the corresponding layer potentials. In regard to the homogeneous Neumann problem, the previous TDBEM based on the OBIE with $d=1$ can be unstable, whereas it was found that the BMBIE with $d=2$ can be stable and accurate. The present study will enhance the usefulness of the TDBEM for 3D scalar wave problems.

description: The transport and noise properties of Pr_{0.7}Ca_{0.3}MnO_{3} epitaxial thin films in the temperature range from room temperature to 160 K are reported. It is shown that both the broadband 1/f noise properties and the dependence of resistance on electric field are consistent with the idea of a collective electrical transport, as in the classical model of sliding charge density waves. On the other hand, the observations cannot be reconciled with standard models of charge ordering and charge melting. Methodologically, it is proposed to consider noise-spectra analysis as a unique tool for the identification of the transport mechanism in such highly correlated systems. On the basis of the results, the electrical transport is envisaged as one of the most effective ways to understand the nature of the insulating, charge-modulated ground states in manganites.

description: The analytical theory of chirped dissipative soliton solutions of nonlinear complex Ginzburg-Landau equation is exposed. Obtained approximate solutions are easily traceable within an extremely broad range of the equation parameters and allow a clear physical interpretation as a representation of the strongly chirped pulses in mode-locked both solid-state and fiber oscillators. Scaling properties of such pulses demonstrate a feasibility of sub-mJ pulse generation in the continuous-wave mode-locking regime directly from an oscillator operating at the MHz repetition rate.

title: From Housewives to Protesters: The Story of Mormons for the Equal Rights Amendment
Creators: name: Morrill, Kelli N.
Publisher: name: Utah State University
Year: 2018

description: On November 17, 1980, twenty Mormon women and one man were arrested on criminal trespassing charges after chaining themselves to the Bellevue, Washington LDS Temple gate. The news media extensively covered the event due to the shocking photos of middle-aged housewives, covered in large chains, holding protest signs and being escorted to police cars. These women were part of the group Mormons for the Equal Rights Amendment (MERA) and were protesting the LDS Church’s opposition to the ERA. The LDS Church actively opposed the ERA and played an important role in influencing the vote in key states leading to its eventual failure. However, ERA literature generally ignores the LDS Church and their influence, instead attributing the ERA’s failure to lack of appeal to lower class and minority women, the ratification process, and confusing messaging about the amendment. Literature that does discuss the LDS Church and its opposition to the ERA fails to tell the story of the small, but bold and attention grabbing group of Mormon women who organized a campaign in direct opposition to the position of their church. This thesis begins with an evaluation of MERA’s use of sacred space in protest, and their portrayal in the media. It then explores how MERA re-appropriated LDS hymns, rituals and language to assert their power and express discontent with the church’s position on ERA, and concludes with an evaluation of the institutional and social consequences MERA members faced as a result of their activism.

description: Kinder werden häufig vor Fremden gewarnt, die sie auf dem Nachhauseweg ansprechen. Doch wie steht es um Fremde, die sich im Netz hinter dem Profil eines Kindes verstecken? Vor dem Hintergrund steigender Fälle von Cybergrooming war es Ziel dieser Pilotstudie, eine Bestandsaufnahme über das Vertrauen von Kindern der dritten und sechsten Klasse in „gleichaltrige“ Fremde im Internet zu geben. Darüber hinaus gewährt die Studie Einblicke in Erfahrungen, die Kinder mit Fake-Profilen, sprich Profilen mit unwahren Identitätsinformationen, gemacht haben. Der Versuchsaufbau folgte einem 2 x 2-faktoriellen quasiexperimentellen Design mit dem Zwischensubjektfaktor „Alter“ (3. Klasse vs. 6. Klasse) und dem Innersubjektfaktor „Ort des Kontakts“ (offline vs. online). Die Stichprobe bildeten 58 Schüler:innen der dritten (n = 31) und sechsten Klasse (n = 27). Es wurde ein Fragebogen genutzt, der die Bewertung der Vertrauenswürdigkeit der Fremden, das Vertrauen in deren Identitätsinformationen sowie Erfahrungen mit Fake-Profilen erfasste. Die Ergebnisse zeigen, dass Kinder Fremde online als signifikant weniger vertrauenswürdig einschätzen im Vergleich zu Fremden offline. Darüber hinaus vertrauten dem Online-Fremden die älteren Sechstklässler:innen signifikant weniger als die Drittklässler:innen. Fast jedes zweite Kind gab Erfahrung mit Fake-Profilen an, jedoch wurden nur wenige geeignete Erkennungsmerkmale für diese genannt. Aus den Ergebnissen lässt sich ableiten, dass Kinder bereits um die Gefahr von Fake-Profilen wissen, allerdings scheinen sie teilweise ratlos zu sein, wenn es um deren Erkennung geht. Die Studie bietet einige Ansatzpunkte für zukünftige Forschung, die zum Abschluss diskutiert werden.

description: Abstract

In today's digital era, Content Delivery Networks (CDNs) are crucial for efficient content delivery. Leveraging Application Programming Interfaces (APIs) in CDN-based media systems offers many opportunities, such as enhanced content delivery and improved user experiences. This research aims to identify the opportunities and challenges of leveraging APIs for CDN-based media systems. A qualitative approach is used by reviewing relevant literature and industry case studies. The results show that APIs can increase productivity and monetize digital assets but also face challenges such as the complexity of the CDN ecosystem and API management. In conclusion, while there are many opportunities in leveraging APIs for CDNs, media organizations need to address technical and operational challenges to maximize their benefits.

description: Granger causality is a statistical notion of causal influence based on prediction via vector autoregression. Developed originally in the field of econometrics, it has since found application in a broader arena, particularly in neuroscience. More recently transfer entropy, an information-theoretic measure of time-directed information transfer between jointly dependent processes, has gained traction in a similarly wide field. While it has been recognized that the two concepts must be related, the exact relationship has until now not been formally described. Here we show that for Gaussian variables, Granger causality and transfer entropy are entirely equivalent, thus bridging autoregressive and information-theoretic approaches to data-driven causal inference.

Further, the adsorption behavior of produced material was tested by performing batch adsorption tests in contaminated water samples using a ratio of 1:1 (g/L) for 24 hours. groundwater analysis indicated that Acacia gum improved the pH value to neutral and remove a high quantity of organic pollutants; Additionally, the treated water sample has the same excellent class suitable for irrigation applications according to the Wilcox diagram. In consequence, the present study suggests an effective, eco-friendly, and economical adsorption process intending to mitigate environmental risk sustainably.

The luminosity and stellar mass Fundamental Plane of early-type galaxies

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: From a sample of ~50000 early-type galaxies from the SDSS, we measured the traditional Fundamental Plane in four bands. We then replaced luminosity with stellar mass, and measured the "stellar mass" FP. The FP steepens slightly as one moves from shorter to longer wavelengths: the orthogonal fit has slope 1.40 in g and 1.47 in z. The FP is thinner at longer wavelengths: scatter is 0.062 dex in g, 0.054 dex in z. The scatter is larger at small galaxy sizes/masses; at large masses measurement errors account for essentially all of the observed scatter. The FP steepens further when luminosity is replaced with stellar mass, to slope ~ 1.6. The intrinsic scatter also reduces further, to 0.048 dex. Since color and stellar mass-to-light ratio are closely related, this explains why color can be thought of as the fourth FP parameter. However, the slope of the stellar mass FP remains shallower than the value of 2 associated with the virial theorem. This is because the ratio of dynamical to stellar mass increases at large masses as M_d^0.17. The face-on view of the stellar mass kappa-space suggests that there is an upper limit to the stellar density for a given dynamical mass, and this decreases at large masses: M_*/R_e^3 ~ M_d^-4/3. We also study how the estimated coefficients a and b of the FP are affected by other selection effects (e.g. excluding small sigma biases a high; excluding fainter L biases a low). These biases are seen in FPs which have no intrinsic curvature, so the observation that a and b scale with L and sigma is not, by itself, evidence that the Plane is warped. We show that the FP appears to curve sharply downwards at the small mass end, and more gradually downwards towards larger masses. Whereas the drop at small sizes is real, most of the latter effect is due to correlated errors.

description: We report the results of new transit observations for the three hot Jupiter-like planets HATP-36b, HATP-56b and WASP-52b respectively. Transit timing variations (TTVs) are presented for these systems based on observations that span the period 2016 - 2020. The data were collected with the 0.6 m telescope at Adiyaman University (ADYU60, Turkey) and the 1.0 m telescope at TÜBİTAK National Observatory (TUG, Turkey). Global fits were performed to the combined light curves for each system along with the corresponding radial velocity (RV) data taken from the literature. The extracted parameters (for all three systems) are found to be consistent with the values from previous studies. Through fits to the combined mid-transit times data from our observations and the data available in the literature, an updated linear ephemeris is obtained for each system. Although a number of potential outliers are noted in the respective O-C diagrams, the majority of the data are consistent within the 3$σ$ confidence level implying a lack of convincing evidence for the existence of additional objects in the systems studied.

title: Modeling the Spread of Alfalfa Stem Nematodes: Insights into their Dynamics and Control
Creators: name: Jordan, Scott G.
Publisher: name: Utah State University
Year: 2018

description: Alfalfa is a major cash crop in the western United States, where fields that are infested with the alfalfa stem nematode (Ditylenchus dipsaci) can be found. With no nematicides available to control alfalfa stem nematode spread, growers can use nematode resistant varieties of alfalfa to manage nematode populations in a field. A deterministic, discrete-time, host-parasite model is presented that describes the spread of alfalfa stem nematodes on resistant hosts that was fit to experimental data obtained in Weber County, Utah. Numerical results obtained from simulations with the model are used to compare how varying levels of resistance can affect harvest yield.
Resistant varieties can also affect the invasion speeds of epidemics in crops. A continuous time, spatial model is presented that describes how these resistant varieties affect invasion speeds in general crop systems. Speeds of traveling wave fronts are determined for simple epidemics in crops that contain a mixture of resistant and non-resistant hosts. For the model, it was found that the wave speeds will slow down as highly nematode resistant varieties of alfalfa are used.
The speed of invasion for the alfalfa stem nematode can be determined by using a mathematical relationship that is know as the contact distribution. We present a spatial model for the spread of alfalfa stem nematodes that uses a Gaussian distribution as the contact distribution of the alfalfa stem nematodes, which was determined by experimental data. Using this contact distribution we are able to approximate the speed of nematode invasive fronts in absence of advection, i.e. without nematode trans-port through flood irrigation. The contact distribution is then used to calculate front speeds when resistant varieties of alfalfa are introduced. We found that, unsurprisingly, invasive speeds are relatively low and cannot support the rapid dispersal of the disease among fields as seen in practice. However, this result leads to conjecture that changing current irrigation practices, from flood to sprinkle irrigation, could effectively contribute to control the spread of alfalfa stem nematodes.
Resistant varieties of alfalfa can be used to effectively control the spread of the alfalfa stem nematode. In this work we have shown that using resistant varieties of alfalfa can increase yield up to 83%, they can slow down invasion speeds of nematodes, and switching from flood to sprinkler irrigation could effectively contribute to the control of the alfalfa stem nematode.

description: The aim of this PhD thesis, developed in the framework of the Italian Agroscenari research project, is to compare current irrigation volumes in two study area in Emilia-Romagna with the likely irrigation under climate change conditions. This comparison was carried out between the reference period 1961-1990, as defined by WMO, and the 2021-2050 period. For this period, multi-model climatic projections on the two study areas were available.
So, the climatic projections were analyzed in term of their impact on irrigation demand and adaptation strategies for fruit and horticultural crops in the study area of Faenza, with a detailed analysis for kiwifruit vine, and for horticultural crops in Piacenza plan, focusing on the irrigation water needs of tomato.
We produced downscaled climatic projections (based on A1B Ipcc emission scenario) for the two study areas. The climate change impacts for the period 2021-2050 on crop irrigation water needs and other agrometeorological index were assessed by means of the Criteria water balance model, in the two versions available, Criteria BdP (local) and Geo (spatial) with different levels of detail. We found in general for both the areas an irrigation demand increase of about +10% comparing the 2021-2050 period with the reference years 1961-1990, but no substantial differences with more recent years (1991-2008), mainly due to a projected increase in spring precipitation compensating the projected higher summer temperature and evapotranspiration. As a consequence, it is not forecasted a dramatic increase in the irrigation volumes with respect to the current volumes.

description: We examine the bar instability in galactic models with an exponential disk and a cuspy dark matter (DM) halo with a Navarro-Frenk-White (NFW) cosmological density profile. We construct equilibrium models from a 3-integral composite distribution function that are subject to the bar instability. We generate a sequence of models with a range of mass resolution from 1.8K to 18M particles in the disk and 10K to 100M particles in the halo along with a multi-mass model with an effective resolution of ~10^10 particles. We describe how mass resolution affects the bar instability, including its linear growth phase, the buckling instability, pattern speed decay through the resonant transfer of angular momentum to the DM halo, and the possible destruction of the halo cusp. Our higher resolution simulations show a converging spectrum of discrete resonance interactions between the bar and DM halo orbits. As the pattern speed decays, orbital resonances sweep through most of the DM halo phase space and widely distribute angular momentum among the halo particles. The halo does not develop a flat density core and preserves the cusp, except in the region dominated by gravitational softening. The formation of the bar increases the central stellar density and the DM is compressed adiabatically increasing the halo central density by 1.7X. Overall, the evolution of the bar displays a convergent behavior for halo particle numbers between 1M and 10M particles, when comparing bar growth, pattern speed evolution, the DM halo density profile and a nonlinear analysis of the orbital resonances. Higher resolution simulations clearly illustrate the importance of discrete resonances in transporting the angular momentum from the bar to the halo.

description: Abstract

The aim of this study was to determine the impact of quality culture on building a green organizational identity. This study also examined the moderating role of job satisfaction in the relationship between quality culture and green organizational identity in Private Jordanian Universities. This study’s population consisted of Deans of Colleges, Heads of academic departments and Unit directors in these universities. A questionnaire was used as a tool to collect data. An appropriate sample of 140 individuals was taken. SPSS software was used to analyze 98 questionnaires that were collected. One of the most important findings of this study was the presence of a statistically significant effect of quality culture on green organizational identity. This study also revealed the moderating role of job satisfaction in the relationship between quality culture and the Green Organizational Identity. The recommendations from this study include encouraging administrators of Private Jordanian Universities to give priority and importance to spreading a quality culture that supports building a green organizational identity that is also keen on raising the level of job satisfaction amongst employees in Private Jordanian Universities in order to improve the image of their green organizational identity. Universities should also incorporate environmental concerns in their vision and strategies in a way that enhances their level of evaluation and raises their level of competitiveness.

description: In this Rapid Communication we investigate spatially constrained networks that realize optimal synchronization properties. After arguing that spatial constraints can be imposed by limiting the amount of `wire' available to connect nodes distributed in space, we use numerical optimization methods to construct networks that realize different trade-offs between optimal synchronization and spatial constraints. Over a large range of parameters such optimal networks are found to have a link length distribution characterized by power law tails $P(l)\propto l^{-α}$, with exponents $α$ increasing as the networks become more constrained in space. It is also shown that the optimal networks, which constitute a particular type of small world network, are characterized by the presence of nodes of distinctly larger than average degree around which long distance links are centred.
title: They Have No Ears to Hear My Pleas: Short Stories of the Post-Apocalypse
Creators: name: Kemp, Keoki W.
Publisher: name: Utah State University
Year: 2018

description: This is a creative thesis consisting of two short stories in the post-apocalyptic genre. A genre that highlights suffering, societal trauma, and the effects of trauma and loss on the human psyche. This genre asks the reader to be sympathetic to these extreme plights. Post-apocalyptic narratives also feature classic heroes who come out on top, despite the genre’s harrowing settings. The two stories featured in this creative thesis are an answer to my inquiry into the genre and seeks not only to show what makes post-apocalyptic literature entertaining but also worthy of literary merit.
The two short stories that constitute this body of work are “A Muddled Canvas,” and “They Have No Ears to Hear My Pleas.” The first story, “A Muddled Canvas,” asks what responsibility God, the protagonist, has to those who remain after the apocalypse he created. The story follows God as he tries to come to terms with the effects his actions have on his creations. The other story, “They Have No Ears to Hear My Pleas,” follows the life of a therapist turned apathetic to his clients’ issues because of the apocalypse. After so much time spent helping others, he develops a bad case of compassion fatigue.

description: The single glitch observed in PSR B1821-24, a millisecond pulsar in M28, is unusual on two counts. First, the magnitude of this glitch is at least an order of magnitude smaller ($Δν/ ν\sim 10^{-11}$) than the smallest glitch observed to date. Secondly, all other glitching pulsars have strong magnetic fields with $B \gsim 10^{11} G$ and are young, whereas PSR B1821-24 is an old recycled pulsar with a field strength of $2.25\times10^9 G$. We have suggested earlier that some of the recycled pulsars could actually be strange quark stars. In this work we argue that the crustal properties of such a {\em strange} pulsar are just right to give rise to a glitch of this magnitude, explaining the scarcity of larger glitches in millisecond pulsars.

description: Novel multicaloric cooling utilizing the giant caloric response of Ni-Mn-based metamagnetic shape-memory alloys to different external stimuli such as magnetic field, uniaxial stress and hydrostatic pressure is a promising candidate for energy-efficient and environmentally-friendly refrigeration. However, the role of microstructure when several external fields are applied simultaneously or sequentially has been scarcely discussed in literature. Here, we synthesized ternary Ni-Mn-In alloys by suction casting and arc melting and analyzed the microstructural influence on the response to magnetic fields and uniaxial stress. By combining SEM-EBSD and stress-strain data, a significant effect of texture on the stress-induced martensitic transformation is revealed. It is shown that a <001> texture can strongly reduce the critical transformation stresses. The effect of grain size on the material failure is demonstrated and its influence on the magnetic-field-induced transformation dynamics is investigated. Temperature-stress and temperature-magnetic field phase diagrams are established and single caloric performances are characterized in terms of $Δ{s_T}$ and $Δ{T_{ad}}$. The cyclic $Δ{T_{ad}}$ values are compared to the ones achieved in the multicaloric exploiting-hysteresis cycle. It turns out that a suction-cast microstructure and the combination of both stimuli enables outstanding caloric effects in moderate external fields which can significantly exceed the single caloric performances. In particular for Ni-Mn-In, the maximum cyclic effect in magnetic fields of 1.9 T is increased by more than 200 % to -4.1 K when a moderate sequential stress of 55 MPa is applied. Our results illustrate the crucial role of microstructure for multicaloric cooling using Ni-Mn-based metamagnetic shape-memory alloys.

description: Total cross sections for single ionization and excitation of molecular hydrogen by antiproton impact are presented over a wide range of impact energy from 1 keV to 6.5 MeV. A nonpertubative time-dependent close-coupling method is applied to fully treat the correlated dynamics of the electrons. Good agreement is obtained between the present calculations and experimental measurements of single-ionization cross sections at high energies, whereas some discrepancies with the experiment are found around the maximum. The importance of the molecular geometry and a full two-electron description is demonstrated. The present findings provide benchmark results which might be useful for the development of molecular models.

description: Multiqubit entanglement is extremely important to perform truly secure quantum optical communication and computing operations. However, the efficient generation of long-range entanglement over extended time periods between multiple qubits randomly distributed in a photonic system remains an outstanding challenge. This constraint is mainly due to the detrimental effects of decoherence and dephasing. To alleviate this issue, we present engineered epsilon-near-zero (ENZ) nanostructures that can maximize the coherence of light-matter interactions at room temperature. We investigate a practical ENZ plasmonic waveguide system which simultaneously achieves multiqubit entanglement in elongated distances, extended time periods, and, even more importantly, independent of the emitters positions. More specifically, we present efficient transient entanglement between three and four optical qubits mediated by ENZ with results that can be easily generalized to an arbitrary number of emitters. The entanglement between multiple qubits is characterized by computing the negativity metric applied for the first time to the proposed nanophotonic ENZ configuration. The ENZ response is found to be substantially advantageous to boost the coherence between multiple emitters compared to alternative plasmonic waveguide schemes. Finally, the superradiance collective emission response at the ENZ resonance is utilized to design a new high fidelity two-qubit quantum phase gate that can be used in various emerging quantum computing applications.

description: Graphene sponge electrodes were employed for chlorine-free inactivation of Escherichia coli from low conductivity water. The nitrogen-doped reduced graphene oxide (NRGO) sponge anode bearing more positive charge achieved complete E. coli inactivation (i.e., 5 log removal) in the anode-cathode configuration at 115 A m-2, versus 2.6 log removal using boron-doped reduced graphene oxide sponge anode. The bacteria were mainly inactivated via electrosorption and electroporation, as confirmed by the scanning electron microscopy. Storage of the electrochemically treated samples revealed further killing of the bacteria due to the damaged cell membranes. When using real tap water, 5.5 log E. coli removal required 5.70 kWh m-3, which was drastically lowered to 1.38 kWh m-3 using intermittent current and thus exploiting the capacitive properties of graphene. The developed graphene sponge anode does not form any chlorine, chlorate, or perchlorate, and holds great promise for efficient electro-disinfection without forming toxic disinfection byproducts.

description: The discovery of Epsilon Indi Ba and Bb, a nearby binary brown dwarf system with a main-sequence companion, allows a concerted campaign to characterise the physical parameters of two T dwarfs providing benchmarks against which atmospheric and evolutionary models can be tested. Some recent observations suggest the models at low mass and intermediate age may not reflect reality with, however, few conclusive tests. We are carrying out a comprehensive characterisation of these, the nearest known brown dwarfs, to allow constraints to be placed upon models of cool field dwarfs. We present broadband photometry from the V- to M-band and the individual spectrum of both components from 0.6-5.1 microns at a resolution of up to R=5000. A custom analytic profile fitting routine was implemented to extract the blended spectra and photometry of both components separated by 0.7 arcsec. We confirm the spectral types to be T1 and T6, and notably, we do not detect lithium at 6708A in the more massive object which may be indicative both of the age of the system and the mass of the components.

Image mediators in paired-associate learning : properties of verbal labels and instructions
Creators: name: Stanzl, Ingeborg J. F.

Year: 2010

description: This study investigated the effects of properties of verbal labels and instructions on paired-associate learning. Predictions concerning the independent effects of associative intra-pair relatedness, instructions, and the directing function of the verbal label were made for the dependent variable. A mediation hypothesis stressing the role of imagery in associative learning and a coding hypothesis stating that "representative" verbal labels may function as conceptual rules, in that they direct stimulus selection and unitary encoding of stimulus and response, guided this work. Unitary imagery instructions, requiring subjects to draw the unitary image, were expected to facilitate the directing function of the verbal label; separate imagery instructions, requiring subjects to draw only the stimulus image, were expected to inhibit it; standard paired-associate (PA) instructions were used as a control condition. Two lists of 18 pairs of incomplete figure-stimulus and concrete noun-response combinations, each, were constructed. Each list was homogeneous, regarding the level of associative intra-pair relatedness, which was either high or low in the respective lists. The same stimulus figures and nouns were used in both lists, but in List 1, the response nouns were dominant associates of the incomplete figures, and in List 2, they were remote associates. Subjects were given one of three sets of instructions to learn either List 1 or List 2. A study-test trial method was employed with one study trial (drawing activity) and two PA recall test trials. The assumption that even originally remote associates would direct coding of incomplete figure stimuli as complete figures was supported. PA recall performance in the unitary imagery group was equal to PA recall performance in the standard PA group. Both groups correctly recalled a significantly greater number of responses than the separate imagery group, as had been hypothesized. Further the hypothesis that PA learning efficacy in List 1 was significantly greater than in List 2 was confirmed. The effect of associative intra-pair related-ness was found to be independent of the effect of the directing, property of the verbal label on unitary encoding of stimulus and response items. The associative property of the verbal label affects unitary image generation because images are more readily available for associatively related pairs than for unrelated ones. The directing property of the verbal label seems to affect the coding process as such, since verbal labels seem to function as conceptual rules for relating the pair items, much as unitary imagery instructions do. The results were interpreted to indicate that each of these factors independently exerts its influence at the acquisition phase of associative learning, because each affects the generation of unitary images which mediate recall of the response at the test trial.
