description: Catalysts with well-defined surfaces are used to enhance the fundamental understanding of structure-function relationships which are hard to develop with polycrystalline materials whose surfaces are a complex mixture of various facets and defects. This dissertation reports the synthesis of ceria nanoshapes, (100) dominant cubes and (111) dominant octahedra, along with grafting techniques used to improve the control of supported oxides and reduce the impact of defects. These ceria nanoshapes were used to investigate how surface structure influences acid-base properties and defects were minimized by tuning calcination conditions. The (111) facet displayed a higher density of stronger acidic sites in comparison to the (100) facet which facilitated 2-propanol dehydration to propene. The (100) facet had a similar density of basic sites but dehydrogenation to acetone was enhanced by stronger basic sites. Supported vanadium oxides are excellent catalysts for redox reactions such as methanol oxidative dehydrogenation (ODH) to produce formaldehyde. Vanadia was deposited on ceria nanocubes using traditional incipient wetness impregnation and a liquid-phase chemical grafting technique to study the influence of loading and deposition method on vanadia structure and methanol ODH activity. Both methods generated well-dispersed vanadia monomers at low loadings but, as vanadia loadings approached monolayer coverage, samples synthesized using chemical grafting showed enhanced dispersion. Bare ceria is responsible for the undesired complete oxidation of methanol to form CO and CO2 which was minimized using chemical grafting of vanadia. Smaller vanadia species expressed greater activity during methanol ODH and improved dispersion at high loadings using chemical grafting increased methanol conversion and selectivity to formaldehyde. This grafting technique was extended to depositing silica on ceria nanoshapes to selectively titrate defect sites with less redox-active material and subsequently depositing vanadia on the remaining pristine ceria facets. After silica deposition, methanol ODH catalysis was no longer governed by differences in ceria defect density and was instead consistent with surface science and theoretical studies which predict (100) to be more active than (111) due to the coordination environments of the intrinsic facets. The knowledge gained using these materials are important in enabling the rational, informed design and improvement of catalysts.

description: We show that the BPS spectrum of pure SU(3) four-dimensional super Yang-Mills with N=2 supersymmetry exhibits a surprising phenomenon: there are regions of the Coulomb branch where the growth of the BPS degeneracies with the charge is exponential. We show this using spectral networks and independently using wall-crossing formulae and quiver methods. The computations using spectral networks provide a very nontrivial example of how these networks determine the four-dimensional BPS spectrum. We comment on some physical implications of the wild spectrum: for example, exponentially many field-theoretic BPS states with large charge are gigantic. Finally, we exhibit some surprising, thus far unexplained, regularities of the BPS spectrum.

description: Service-oriented sensor-actuator networks (SOSANETs) are deployed in health-critical applications like patient monitoring and have to fulfill strong safety requirements. However, a framework for the rigorous formal modeling and analysis of SOSANETs does not exist. In particular, there is currently no support for the verification of correct network behavior after node failure or loss/addition of communication links. To overcome this problem, we propose a formal framework for SOSANETs. The main idea is to base our framework on the π-calculus, a formally defined, compositional and well-established formalism. We choose KLAIM, an existing formal language based on the π-calculus as the foundation for our framework. With that, we are able to formally model SOSANETs with possible topology changes and network failures. This provides the basis for our future work on prediction, analysis and verification of the network behavior of these systems. Furthermore, we illustrate the real-life applicability of this approach by modeling and extending a use case scenario from the medical domain.

description: Aim: In the context of global aging, further exploration is needed to understand the associations of varying exercise intensities and frequencies on frailty among middle-aged and older individuals. Findings: As people age, their participation in physical activity tends to decrease. A longitudinal association was observed between moderate-intensity physical activity more than once a week and lower incidence of frailty among middle-aged and older adults, compared to participants with lower frequency of moderate physical activity. Message: Further interventional studies are needed to clarify the causal relationship between different intensities of physical activity and preventing frailty.
description: Background: Global aging is leading to an increase in frailty patients, and physical activity (PA) may have an impact on frail in middle-aged and older population. This study aimed to explore the relationship between the frequency of different PA intensities and the incidence and prevalence of frailty in middle-aged and older adults based on the Survey of Health, Ageing, and Retirement in Europe (SHARE). Method: Self-reported questionnaires were used to obtain information on demographics and PA, and frailty was assessed using the SHARE Frailty Instrument (SHARE-FI). Cox regression and logistic regression models were used to explore the association between PA and frailty and stratified according to middle or old age. Results: Among 6315 baseline non-frail participants aged 44–96 years, 16.1% developed frailty over 4 years, with higher incidence and prevalence in women ( P  < 0.05). Women accounting for 55.80% of the sample. The frequency of participants participating in sports decreased over 4 years ( P  < 0.05). Compared with participants who engaged in PA more than once a week, participants who engaged in moderated PA less frequently had a higher risk of new-onset frailty (HR: 3.174–6.115), and participants who engaged in vigorous PA 1–3 times a month had a higher risk of new-onset frailty (HR: 1.335). Participation in low-frequency moderate PA and vigorous PA 1–3 times per month were positively associated with the prevalence of frailty ( P  < 0.05). Conclusion: Physical activity frequency decreases with age in middle-aged and older adults. Those adults who engage in moderate PA more than once a week have a lower risk of incidence of frailty, compared to those with more sedentary life-styles. Additionally, women need to pay more attention to frailty management.

description: The Butler-Tarkington Neighborhood Association (BTNA) is a community group organized in 1956 by a few concerned couples living in the Butler-Tarkington neighborhood on the north side of Indianapolis. These couples, both Black and white, witnessed a demographic change in their community as their white neighbors fled for the suburbs as the black population expanded. The BTNA, inspired to create an organization that would promote residential integration rather than continued segregation, worked to educate neighbors on the realities of integration, promote neighborhood conversation and comradery, and worked to influence the local and state governments on the impact of segregation that harmed their community. One of the first neighborhood organizations of its kind in the country, the BTNA still exists today, but little is known about their early history. This paper looks at the BTNA’s efforts to promote residential segregation in their community through activism, conversation, and legislative change. Additionally, this paper analyzes the BTNA success in its efforts to integrate the community during their first decade of existence.

description: We point out that in the large field regime, the recently proposed superconformal D-term inflation model coincides with the Starobinsky model. In this regime, the inflaton field dominates over the Planck mass in the gravitational kinetic term in the Jordan frame. Slow-roll inflation is realized in the large field regime for sufficiently large gauge couplings. The Starobinsky model generally emerges as an effective description of slow-roll inflation if a Jordan frame exists where, for large inflaton field values, the action is scale invariant and the ratio \hat λ of the inflaton self-coupling and the nonminimal coupling to gravity is tiny. The interpretation of this effective coupling is different in different models. In superconformal D-term inflation it is determined by the scale of grand unification, \hat λ ~ (Λ_{GUT}/M_P)^4.

description: During processing the observations of the intermediate polar 1RXS J180340.0+401214, obtained 26.05.2012 at the 60-cm telescope of the Mt. Suhora observatory (Krakow, Poland), variability of 2MASS J18024395+4003309 was discovered. As this object was not listed in the "General Catalogue of Variable Stars" or "Variable Stars Index", we registered it as VSX J180243.9+400331. Additionally we used 189 separate observations from the Catalina Sky Survey spread over 7 years. The periodogram analysis yields the period of 0d.3348837{\pm}0d.0000002.The object was classified as the Algol-type eclipsing binary with a strong effect of ellipticity. The depths of the primary and secondary minima are nearly identical, which corresponds to a brightness (and maybe) mass ratio close to 1. The statistically optimal degree of the trigonometric polynomial n=4. The most recent minimum occurred at HJD 2456074.4904. The brightness range from our data is 16.56-17.52 (V), 16.18-17.08 (R). The NAV ("New Algol Variable") algorithm was applied for statistically optimal phenomenological modeling and determination of corresponding parameters.

description: Objective: Nutritional assessment of infants in the Newborn Intensive Care Unit (NICU) depends on the performance of accurate, serial anthropometric measurements. In this Level IV NICU, nurses used tape measures more often than length boards making the length measurements inaccurate. The purpose of this study is to determine if an in-person, hands-on length board training program versus a self-instruction poster education, increases the use of length boards to measure length in NICU infants. Methods: Two nursing in-service education training sessions on how to correctly use a length board were held with the NICU staff over two separate two (2-week) periods. One session consisted of a self-direct education training method. The second education method was an in-person interactive learning experience with hands on practice. At the end of each education session, the participants completed the same four-question post-test. One month later, data was collected for one month following each of the training periods on the tool used to obtain linear measurements on infants in the NICU. Statistics: A 2x2 contingency table was constructed using the two qualitative variables of length board uses after the poster education versus length board uses after the live in-service education. Analysis was performed using SAS 9.4 ™ statistical software. Chi squared equals 93.980 with 1 degree of freedom. P-value <0.0001. Results: The month following the self-directed poster education, two hundred ninety-one (291) or 92% measurements were obtained using a tape measure and 19 (7%) obtained using a length board. The month following the interactive, in-service training, one hundred forty-eight (148) or 57% measurements were obtained using a tape measure and 105 (41%) with a length board. Thirty five percent (35%) more length measurements were obtained using a length board after the line in-service training (P-value <0.0001). Conclusion: Nurses in a Level IV Newborn Intensive Care Unit utilized length boards significantly more after a live in-service education than after a self-directed education.

description: Student retreats are not unfamiliar within education. Literature on retreat experiences acknowledges the important role that schools play in supporting social and character development, wellbeing, and the fostering of values. However, little is known of the extent to which the retreat aim and objectives are achieved. This case study qualitatively explored the effectiveness of the retreat experience through interviews with student retreatants and retreat teachers, together with the analysis of school documentation relevant to the retreat. Through a focus on documented purpose, planning and preparation, environmental considerations, program content, staffing; together with perceived value, and the depth of post-retreat follow-up and evaluation, the case study explored these criteria within the context of a Year 11 student retreat in an Australian Anglican school. The overall view of students and teachers recognised the influence of the retreat experience on students’ character-building, values, wellbeing, skill development, including social, and relationship skills, which they transferred back to school and into their personal life, and their overall outlook on life. The discussion of findings enabled the generation of six themes integral to effectiveness. These included: Christian principles; values, morals, and ethics; character-building; wellbeing; retreat enablers; and retreat outcomes from which new understandings on the retreat phenomenon emerged. Nine conclusions were drawn from the case study research. These contributed to new knowledge and underlined the retreat experience as an interdependent educational process central to the wider pastoral and character-building programs of the school. With this knowledge, it is anticipated that school leaders, both within the case study school, and more generally, will be better placed to assess what actions support the enhancement of the overall retreat effectiveness for student development within the mission, life, and culture of the school.

description: We propose the use of the parallel tabu search algorithm (PTS) to solve combinatorial inverse design problems in integrated photonics. To assess the potential of this algorithm, we consider the problem of beam shaping using a two-dimensional arrangement of dielectric scatterers. The performance of PTS is compared to one of the most widely used optimization algorithms in photonics design, the genetic algorithm (GA). We find that PTS can produce comparable or better solutions than the GA, while requiring less computation time and fewer adjustable parameters. For the coherent beam shaping problem as a case study, we demonstrate how PTS can tackle multiobjective optimization problems and represent a robust and efficient alternative to GA.

How U.S. Presidents Are Regarded Historically

Publisher: name: RSAJournal
Year: 2013

description: In April 2013, when covering the opening of his presidential library in Dallas, part of the media attention was drawn by the “unexpected” surge in approval ratings of former President George W. Bush. That surprise came because the 43rd President was very unpopular when he left office in 2009 and because he is still considered by many scholars as one as the “worst Presidents in history”. Although scholars’ judgment and public opinion surveys often seem not to match each other, this paper explains that George W. Bush’s rise is exactly what one would expect, based on the history of other former presidents’ approval ratings. Indeed, retrospective approval ratings typically exceed approval ratings while in office.

description: Communities are fundamental entities for the characterization of the structure of real networks. The standard approach to the identification of communities in networks is based on the optimization of a quality function known as "modularity". Although modularity has been at the center of an intense research activity and many methods for its maximization have been proposed, not much it is yet known about the necessary conditions that communities need to satisfy in order to be detectable with modularity maximization methods. Here, we develop a simple theory to establish these conditions, and we successfully apply it to various classes of network models. Our main result is that heterogeneity in the degree distribution helps modularity to correctly recover the community structure of a network and that, in the realistic case of scale-free networks with degree exponent $γ< 2.5$, modularity is always able to detect the presence of communities.

Following the proofs-as-model-transformations approach, in this paper we consider a formalisation in Constructive Type Theory of the concepts of model and model transformation, and show how the correctness proofs of potentially large ordered model transformations can be systematically assembled from the proofs of the specifications of their parts, making them easier to derive.

Pretending to Be Lincoln

description: Anachronism is a frequent device in Avant-garde theater. From Eugene O’Neill’s plays to the eclogues of the New York poets, representative historical figures have always fluctuated on stage as emblems of power. In the mid-1960s, Adrienne Kennedy brought in her dream-like drama the incongruous presence of black actors dressed like white leaders like Queen Elizabeth and William the Conqueror, in an interracial camouflage which reversed the mocking practice of blackface minstrelsy. In this iconoclastic fashion, the black dramatist appropriated symbols of white power to allude to the failed attempt of her community to find a definition beyond the patterns of non-black hegemony. More recently, Hip-Hop dramatist SuzanLori Parks enacted a similar interracial masquerade, staging Black imper- sonators of the celebrated Abraham Lincoln. In the twin plays The America Play (1992) and Topdog/Underdog, she features the deep estrangement of Americans of African origin dressed in the genteel attire of the white President, in a racialized version of the most popular anti-slavery advocate in American history. Especially in the latter play, which in 2002 was awarded the first Pulitzer Prize for Drama ever assigned to a black woman dramatist, the African-American actors in Lincoln’s garb appear no less “trapped in Blackness” than Adrienne Kennedy’s hallucinated heroines, being artificially framed within a videoculture which neutralizes racial difference and places them in the indeterminate condition of frustrated spectatorship. In the twin plays that Parks dedicates to the “Great Emancipator” of the black race, Lincoln’s lookalikes revive this national icon through a grotesque ritualization, in a post-racial and media-conscious remodulation of the interplay of blackness and power in American history.

In such a system, blockade phenomenon is shown to also occur for pairs of different excited-state atoms, which results in similar intra- and inter-species long-range interactions between ground-state atoms. It suggests that a pseudo spin-1/2 system can be possibly formed in the ground state of ultracold rudibium.
The Madman’s Embarkation

description: This paper analyzes Richard Paul Russo’s 2001 novel Ship of Fools in terms of its use of the eponymous trope, which Russo takes from Sebastian Brant’s 1494 poem Das Narrenschiff and from the European tradition of ship-of-fools narratives dating back to Medieval times, as well as from the historical reality of literal ships of fools plying the waterways of central Europe in the 15th century. In accordance with this tradition, the characters in Russo’s novel act out the same kind of warped, insane behavioral practices as those in previous stories. When faced with the discovery of alien life in the universe, and of this alien life’s utter hostility and brutality, the inhabitants of the generation starship Argonos respond with an inward-turning solipsism utterly at odds with their actual circumstances, thus initiating a cascade of events leading them to near-total ruin. Russo’s handling of the ship-of-fools trope in the story, at once unobtrusive and pervasive, relocates the voyages of the madman from the stretches of Earth’s seas to the empty vastness of space, presenting both as reflective surfaces against which we do not see the reality of our lives, but only the reflections of our psyches – until it is too late.

description: The nearby low-luminosity active galactic nucleus (LLAGN) NGC 4258 has a weak radio continuum component at the galactic center. We investigate its radio spectral properties on the basis of our new observations using the Nobeyama Millimeter Array at 100 GHz and archival data from the Very Large Array (VLA) at 1.7-43 GHz and the James Clerk Maxwell telescope at 347 GHz. The NGC 4258 nuclear component exhibits (1) an intra-month variable and complicated spectral feature at 5-22 GHz and (2) a slightly inverted spectrum at 5-100 GHz (a spectral index of ~0.3) in time-averaged flux densities, which are also apparent in the closest LLAGN M81. These similarities between NGC 4258 and M81 in radio spectral natures in addition to previously known core shift in their AU-scale jet structures produce evidence that the same mechanism drives their nuclei. We interpret the observed spectral property as the superposition of emission spectra originating at different locations with frequency-dependent opacity along the nuclear jet. Quantitative differences between NGC 4258 and M81 in terms of jet/counter jet ratio, radio loudness, and degree of core shift can be consistently understood by fairly relativistic speeds (bulk Lorentz factors of >~ 3) of jet and their quite different inclinations. The picture established from the two closest LLAGNs is useful for understanding the physical origin of unresolved and flat/inverted spectrum radio cores that are prevalently found in LLAGNs, including Sgr A*, with starved supermassive black holes in the present-day universe.

description: The POLARBEAR-2 CosmicMicrowave Background (CMB) experiment aims to observe B-mode polarization with high sensitivity to explore gravitational lensing of CMB and inflationary gravitational waves. POLARBEAR-2 is an upgraded experiment based on POLARBEAR-1, which had first light in January 2012. For POLARBEAR-2, we will build a receiver that has 7,588 Transition Edge Sensor (TES) bolometers coupled to two-band (95 and 150 GHz) polarization-sensitive antennas. For the large array's readout, we employ digital frequency-domain multiplexing and multiplex 32 bolometers through a single superconducting quantum interference device (SQUID). An 8-bolometer frequency-domain multiplexing readout has been deployed on POLARBEAR-1 experiment. Extending that architecture to 32 bolometers requires an increase in the bandwidth of the SQUID electronics to 3 MHz. To achieve this increase in bandwidth, we use Digital Active Nulling (DAN) on the digital frequency multiplexing platform. In this paper, we present requirements and improvements on parasitic inductance and resistance of cryogenic wiring and capacitors used for modulating bolometers. These components are problematic above 1 MHz. We also show that our system is able to bias a bolometer in its superconducting transition at 3 MHz.

Popular culture is usually associated with a marked social and political irresponsibility, committed as it is (or should be) to elicit the most superficial forms of harmless pleasure. But since the very birth of the genre, superheroes have always been self-reflectively engaged in questioning the motivations and consequences of their actions. Spider-Man’s famous motto, “with great powers comes a great responsibility,” dates August 1962, but it fairly describes Superman’s (or Captain America’s) earliest endorsement of “truth, justice, and the American way.” The essay will briefly describe some of the various trajectories superheroes have taken through the decades in facing the moral and political implications of their predicament, showing the main ideological contradictions embedded in this form of expression, as well as the different and conflicting meanings the concept of “responsibility” has come to take.

description: Several methods for monitoring the growth of microalgae in the laboratory have been described in the literature. Direct measurements, such as cell density and biomass yield, are considered as the most reliable methods. Indirect methods generally rely on specific parameters that can be measured as a consequence of the phototrophic activity. While indirect methods are undoubtedly less time-consuming, their relevance needs to be evaluated case by case for the species and the experimental conditions used. In this study, the main objective was to test the relevance of optical density (OD) and basal fluorescence (F0) measurements for monitoring the growth of batch cultures of the benthic diatom Nitzschia palea. Further experiments addressing photosynthetic efficiency, biomass weight and composition, lipid content and fatty acid profile were conducted with the aim of determining the optimal harvesting time for biotechnological applications. Three Canarian strains of Nitzschia palea (BEA 0255B, BEA 0256B and BEA 0392B) were cultured in triplicate 1 L Erlenmeyer flasks with 270 mL FDMed medium for 26 days at an initial cell density of 1.3 x 105 cells mL-1 ± 27% (RSD). Biomass was harvested and further analyzed at two points of the growth curve, one corresponding to the exponential phase (day 9) and the other corresponding to the stationary phase (day 26). The three strains showed their maximum growth rates (μmax) between days 4 and 7 (0.21 – 0.29 day-1), and entered the stationary phase at day 17, maintaining an average concentration of 1.5 x 106 cells mL-1 ± 11 % (RSD). Comparison between cell density, OD and F0 was performed using the data of each replicate of the three strains in the same analysis. The relevance of OD and F0 measurements was demonstrated during the exponential phase, as they both positively correlated with cell density in a linear regression model (days 4 – 17, R2 > 0.87, n = 45). Very poor linear correlation was found during the stationary phase (days 17 – 26, R2 < 0.46, n = 45). The biomass yields of the three strains were comprised in a range of 3.1 – 3.8 mg mL-1 dry weight (DW), without significant differences between strains or growth phases. At day 9, lipid content represented between 9 and 11 % DW, whereas at day 26, lipid content was between 6 and 8 % DW. The lipid content in all three N. palea strains was slightly higher at day 9 compared to day 26, but not significant, and overall low compared to other studies. The preliminary studies on fatty acid composition opens up potential applications for these strains in different biotechnological areas, including nutraceutical and aquaculture sectors.

description: We present work on behavioral specifications of OSGi components. Our behavioral specifications are based on finite automata like formalisms. Behavioral specifications can be used to find appropriate components to interact with, detect incompatibilities between communication protocols of components and potential problems resulting from the interplay of non-deterministic component specifications. These operations can be carried out during development and at runtime of a system. Furthermore, we describe work carried out using the Eclipse based implementation of our framework.

description: We discuss the residual carrier density (n*) near the Dirac point (DP) in graphene estimated by quantum capacitance (CQ) and conductivity measurements. The CQ at the DP has a finite value and is independent of the temperature. A similar behavior is also observed for the conductivity at the DP, because their origin is residual carriers induced externally by charged impurities. The n* extracted from CQ, however, is often smaller than that from the conductivity, suggesting that the mobility in the puddle region is lower than that in the linear region. The CQ measurement should be employed for estimating n* quantitatively.

A systematic literature review of architecture-related dew and fog harvesting

description: Dew and fog harvesting had been the topic of numerous studies since the 2000s to address the global water crisis brought on by climate change, as an alternative and sustainable solution. Though this topic has many connections to architectural science, it is nonetheless alien to academics and practitioners with architectural backgrounds. What research focuses had been done? What research methodologies were employed? What implications and limitations were discovered? This study addresses these questions by conducting a systematic literature review. This study discovered that the effectiveness and efficiency of planar shape-based fog nets and dew condensers continued to dominate the research focus. Although several studies have begun to consider the forms of three-dimensional and biomimicry. One study also started researching the application of this technology to urban settings apart from rural areas affected by water scarcity. The most employed methodology in this research was design testing and review. Some models, prototypes, and developments are implicated as best practices, although the limitations of these studies lay in the physical local context, material selection, methodologies, scalability, water quality, and water quantity. The results of this review provide direction for further research in Indonesia to consider the use of harvesting combination systems in three dimensions form with passive systems and low tech. Moreover, this discovery also opens opportunities for the use of vernacular or traditional architecture and local natural materials that have not been discussed by previous studies.

description: Using data drawn from a web‐based travel cost survey, we jointly model revealed and stated preference trip count data in an attempt to estimate the recreational use value from diving the intentionally sunk ex‐USS Oriskany. Respondents were asked to report (1) their actual trips from the previous year, (2) their anticipated trip in the next year, and (3) their anticipated trip next year assuming a second dive‐able destroyer were sunk in the same vicinity. Results from a single‐site Poisson and negative binomial travel cost model indicate an annual use value of $1,215 per diver associated with current Oriskany‐specific dive trips. Expected annual use value estimates then increase to $2,596 with the “bundling” of a second vessel alongside the Oriskany to create a multiple‐ship artificial reef area.

description: Construal-level theory suggests that people could view novel issues and phenomena like artificial intelligence (AI) as being psychologically distant, irrelevant to people like themselves and even less believable relative to more familiar or salient issues. Synchronously, empirical construal-level theory studies suggest that information related to novel issues like AI is more likely to be shared online when people perceive the topic as being psychologically proximal, relevant to people like themselves and believable. Therefore, understanding how media might encourage information sharing about novel technologies by communicating psychological proximity (e.g., a sense of nearness and personal relevance) is key to understanding how people form perceptions of new innovations and share these perceptions with others. I conducted two studies examining the influence of technology media-system dependency (study 1) and online technology media content (study 2) on AI information sharing online, through psychological proximity to the impacts of AI. In study 1, I surveyed a sample of US citizens 18 years and older about their media habits in relation to AI, and tested a process model predicting AI information sharing from technology media-system dependency. Results suggest an indirect positive association between reliance on media resources to meet goals related to AI and online AI information sharing, through priming psychological proximity. Perceived rate of technological change was found to moderate this model, enhancing the association between dependency and proximity, and the indirect association between dependency and information sharing, through proximity. In study 2, I exposed a sample of US citizens 18 years and older to manipulated media content reporting on the potential economic threats posed by AI. Results suggest that thematically framing the threat of AI primed psychological proximity over episodically framing similar information, contrary to the predictions of construal-level theory. Furthermore, thematically framed content was more shareable through its positive effects on psychological proximity to the impacts of AI and perceived AI threat in serial mediation. Discussions of implications, trajectory of future research and limitations are discussed through the lens of construal-level theory and individual-level media-systems dependency.

description: We present a calibration of the fundamental plane using SDSS Data Release 8. We analysed about 93000 elliptical galaxies up to $z<0.2$, the largest sample used for the calibration of the fundamental plane so far. We incorporated up-to-date K-corrections and used GalaxyZoo data to classify the galaxies in our sample. We derived independent fundamental plane fits in all five Sloan filters u, g, r, i and z. A direct fit using a volume-weighted least-squares method was applied to obtain the coefficients of the fundamental plane, which implicitly corrects for the Malmquist bias. We achieved an accuracy of 15% for the fundamental plane as a distance indicator. We provide a detailed discussion on the calibrations and their influence on the resulting fits. These re-calibrated fundamental plane relations form a well-suited anchor for large-scale peculiar-velocity studies in the nearby universe. In addition to the fundamental plane, we discuss the redshift distribution of the elliptical galaxies and their global parameters.
