The effect of intravenous salt loading on osmoregulation of hydrated glaucous-winged gulls, Larus glaucescens
Creators: name: Raveendran, Lethika
Publisher: name: University of British Columbia
Year: 2010

description: Renal function of fresh water acclimated Glaucous-winged Gulls, Larus qlaucescens, was studied during infusion of hypotonic and hypertonic NaCl. Two experimental protocols were followed. In one, the closed urine collection system (CCS), ureteral urine was collected using catheters glued over ureteral openings of a supine, previously anesthetized gull. In the other, the open urine collection system (OCS), ureteral urine was collected through a funnel placed in the urodeum of a standing, unanesthetized bird. In both protocols, there was continuous saline infusion of hypotonic (hydration) and hypertonic (LOAD) saline at 0.286 ml⋅min⁻¹. Glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), ml(kg⋅min) ⁻¹, were determined by ¹⁴C-polyethylene glycol (PEG) and ³H-para-aminohippuric acid (PAH) clearances. Plasma vasotocin (PAVT, pg⋅ml⁻¹) was measured. At the end of 4 h hydration with 0.02 M NaCl, urine flow was high but matched infusion rate only in CCS birds (CCS, 0.29 ± 0.05; OCS, 0.17 ± 0.03 ml⋅min⁻¹), GFR (CCS, 5.56 ± 0.85; OCS, 5.36 ± 0.77) and ERPF (CCS, 15.80 ± 1.60; OCS, 14.35 ± 1.65) were high; urine sodium (UNa+) concentration was low (CCS, 15.0 ± 7.3; OCS, 36.4 ± 6.0 mEq⋅1⁻¹), UNa+ excretion was low (CCS, 6.38 ± 4.2; OCS, 5.19 uEq⋅min⁻¹) ; urine/plasma PEG ratio (U/PPEG) was high (CCS, 22.4 ± 4.4, OCS, 39.6 ± 8.5); free water clearance (CH₂O) was positive (CCS, 0.143 ± 0.011; OCS, 0.052 ± 0.019 ml⋅min⁻¹) , and PAVT was low (ccs,14.7 ± 7.4; OCS, 16.1 ± 2.4) in both groups. Immediately following infusion of 5 M NaCl, GFR, ERPF and urine flow increased for about 10 mins. Fifteen minutes later, the GFR of CCS gulls fell to 70% of pre-load values (P < 0.05) and in OCS gulls, GFR and ERPF fell to 64% (P < 0.01) and 61% (P < 0.05). Eighty mins after infusion of 5 M NaCl, the GFR and ERPF of CCS gulls returned to pre-LOAD levels, but remained low in OCS gulls. Twenty-five minutes after salt load, urine flow had fallen to 49% (P < 0.05) and remained low. In OCS gulls, urine flow had fallen to 13% (P < 0.001) after 185 mins. In both CCS and OCS gulls, UNa+ concentration and excretion increased significantly. Sixty minutes after salt load, UNa+ excretion returned to pre-LOAD levels but UNa+ concentration remained high in CCS (111.7 ± 57.5) and OCS (132.8 ± 12.5) gulls. U/PPEG attained 134.3 ± 26.5 in CCS and 181.2 ± 32.4 in OCS gulls. CH₂O fell significantly (P < 0.05) in CCS gulls but remained unchanged in OCS gulls. Mean PAVT increased to 122.5 ± 5.5 in CCS and 96.0 ± 12.6 in OCS gulls. In both CCS and OCS gulls, salt gland secretion was initiated but ceased 60 mins after 5M NaCl infusion, although 60% of the load was retained in the gull.

description: In the world where young people feel that the future is no longer a promise but a threat, and science and technology are sources of fears and global problems, a challenging task for education is to support students in imagining a future for the world and for themselves. The aim of the EU-funded project “I SEE” is to create an approach in science education that addresses the problems posed by global unsustainability, the uncertainty of the future, social liquidity and the irrelevance of STEM education for young people. This way, we believe, STEM education can support young people in projecting themselves into the future as agents and active persons, citizens and professionals, and open their minds to future possibilities. In this paper we propose a teaching and learning approach for futurizing science education, and describe how that approach was used to develop the first I SEE module implemented in summer school in June 2017 with students from three countries. In sum, the I SEE teaching and learning approach consists of three stages and learning outcomes connected to each of them: encountering the focal issue; engaging with the interaction between science ideas and future dimensions, and synthesizing the ideas and putting them into practice. The middle stage of the model is the main part, involving future-oriented practices that turn knowledge into future-scaffolding skills. We describe four kinds of such future-oriented practices: a) activities to flesh out the future-oriented structure of scientific discourse, language and concepts; b) activities inspired by futures studies or by the working life and societal matters; c) exposure activities to enlarge the imagination about possible future STEM careers; and d) action competence activities. We conclude the paper by reflecting on our experiences of the implementation of the climate change module with upper secondary school students.

Learning about energy. A real-life approach challenging the present culture of science & engineering
Creators: name: Bartosch, Ilse
Publisher: name: Università degli Studi di Torino
Year: 2018

description: There is an increasing number of publications in various fields of research suggesting that a purely technocratic approach cannot mitigate the current environmental crisis caused by climate change. This goes hand in hand with the criticism expressed by science educators that classroom teaching on energy is mainly based on the conceptual knowledge perspective of science education, which is considered inappropriate for empowering young people to fight in the best interests of the biosphere. Based on the experiences gathered in the R&E project “SOLARbrunn – heading for a future with the sun” the paper highlights some facets of STEM education which seem to be indispensable for empowering young people to contribute to sustainable development. In an interdisciplinary research setting modelled upon Zeidler’s conceptual framework for socio-scientific issues, students at a Secondary Technical and Vocational School in a small Austrian town worked out suggestions for converting a local kindergarten into a ‘green building’. In the course of the project, the traditional view of engineering - constructing technological solutions based on the rigorous mathematical processing of data acquired by diligent measurement – was challenged. When dealing with real world cases where everyday routines are important for planning, implementing and adjusting technical systems, the limitations of the technocratic approach to sustainable development becomes evident. Sustainable development is less a question of enhanced technology; it is rather a question of improving socio-technical practices by means of interactive efforts on the part of various players.

description: We revisit several aspects of the interaction of self-gravitating, slowly varying sources with their own emitted radiation within the context of post-Newtonian approximation to General Relativity. We discuss and clarify the choice of boundary conditions of Green's functions used to determine conservative potentials, and the interplay between the so-called near and far zones, as well as the relation between far zone ultra-violet divergences and emitted power. Both near and far zone contributions are required for the computation of the conservative dynamics. Within a field-theory approach we rederive far-zone self-energy processes, known as tail and memory effects, generalising the calculation of their divergent part to arbitrary order in the post-Newtonian expansion.

description: Science education research emphasizes the need to engage students in socio-scientific issues, empowering them to act in a substantiated manner. This study aims to understand the potential of a collective action initiative, focused on the decreasing honey production issue, and on the students’ empowerment for action. A qualitative research methodology was used with an interpretative stance. The participants were 26 3rd grade students and their teacher. Data was collected from the students written documents, and through an interview with the teacher. Results show that students’ engagement in collective action focused on the decreasing honey production issue, required them to mobilize their scientific knowledge to support their actions, as well as the development of several other competences. Students also became aware of the importance, for every citizen, to substantiate their knowledge in order to act, that acting is crucial to overcome issues that may persist and impact future generations, and that only by engaging in action can change take place. Another highlight was the students’ strong engagement in collective action, allowing them to raise awareness this issue in their local community.

description: To enable the reusability of massive scientific datasets by humans and machines, researchers aim to adhere to the principles of findability, accessibility, interoperability, and reusability (FAIR) for data and artificial intelligence (AI) models. This article provides a domain-agnostic, step-by-step assessment guide to evaluate whether or not a given dataset meets these principles. We demonstrate how to use this guide to evaluate the FAIRness of an open simulated dataset produced by the CMS Collaboration at the CERN Large Hadron Collider. This dataset consists of Higgs boson decays and quark and gluon background, and is available through the CERN Open Data Portal. We use additional available tools to assess the FAIRness of this dataset, and incorporate feedback from members of the FAIR community to validate our results. This article is accompanied by a Jupyter notebook to visualize and explore this dataset. This study marks the first in a planned series of articles that will guide scientists in the creation of FAIR AI models and datasets in high energy particle physics.

description: After providing a background to futures thinking in science, and exploring the literature around transdisciplinary approaches to curriculum, we present a futures pedagogy. We detail case studies from a year-long professional learning action research project during which primary school teachers developed curriculum for the Anthropocene, focusing on the topic of fresh water. Why fresh water? Living in South Australia—the driest state in the driest continent—water is a scarce and precious resource, and our main water supply, the River Murray, is in trouble. Water is an integral part of Earth’s ecosystem and plays a vital role in our survival (Flannery, 2010; Laszlo, 2014). Water literacy therefore has a genuine and important place in the school curriculum.

Working with teachers and their students, the Water Literacies Project provided an ideal opportunity to explore a range of pedagogical approaches and practices which connect students to their everyday world, both now and in their possible futures, through place-based learning. We describe the use of futures scenario writing in an issues-based transdisciplinary curriculum unit on the theme of Water, driven by Year 5 teachers and their students from three primary schools: two located on the River Murray and one near metropolitan Adelaide. All three schools focused on a local wetland. The research was informed by teacher interviews, student and teacher journals, student work samples, and teacher presentations at workshops and conferences. We report on two aspects of the project: (1) the implementation of futures pedagogy, including the challenges it presented to the teachers and their students and (2) an emerging analysis of students’ views of the future and implications for further work around the futures pedagogical framework. Personal stories in relation to water, prior knowledge on the nature of water, experiential excursions to learn about water ecology and stories that examine the cultural significance of water—locally and not so locally—are featured (Lloyd, 2011; Paige & Lloyd, 2016). The outcome of our project is the development of comprehensive adventurous transdisciplinary units of work around water and connection to local place.

description: Due to the advancement of nano-satellite technology, CubeSats and fleets of CubeSats can form an alternative to high-cost large-size satellite missions with the advantage of extended spatial coverage. One of these initiatives is the Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT) mission concept, aimed at detecting and localizing gamma-ray bursts with an efficiency and accuracy comparable to large gamma-ray space observatories. While precise attitude control is not necessary for such a mission, attitude determination is an important issue in the interpretation of scintillator detector data as well as optimizing downlink telemetry. The employment of star trackers is not always a viable option for such small satellites, hence another alternative is necessary. A new method is proposed in this series of papers, utilizing thermal imaging sensors to provide simultaneous measurement of the attitude of the Sun and the horizon by employing a homogeneous array of such detectors. The combination with Sun and horizon detection w.r.t. the spacecraft would allow the full 3-DoF recovery of its attitude. In this paper we determine the spherical projection function of the MLX90640 infrasensors planned to be used for this purpose. We apply a polynomial transformation with radial corrections to map the spatial coordinates to the sensor plane. With the determined projection function the location of an infrared point source can be determined with an accuracy of ~40', well below the design goals of a nano-satellite designed for gamma-ray detection.

description: Certain biomaterials are capable of inducing the secretion of Vascular Endothelial Growth Factor (VEGF) from cells exposed to their biochemical influence, which plays a vital role in stimulating angiogenesis. Looking for this capacity, in this study three porous glasses were synthesized and characterized. The objective of this study was to determine the concentration of the glass particles that, being out of the cytotoxic range, could increase VEGF secretion. The viability of cultivated bone marrow stromal cells (ST-2) was assessed. The samples were examined with light microscopy (LM) after the histochemical staining for haematoxylin and eosin (HE). The biological activity of glasses was evaluated in terms of the influence of the Cu2+ and Sr2+ ions on the cells. The dissolution products of CuSr-1 and CuSr-2.5 produced the highest secretion of VEGF from ST-2 cells after 48 h of incubation. The combination of Cu2+ and Sr2+ lays the foundation for engineering a bioactive glass than can lead to vascularized, functional bone tissue when used in bone regeneration applications.

Science Education Futures. Science Education as if the Whole Earth Mattered.
Creators: name: Gray, Donald
Publisher: name: Università degli Studi di Torino
Year: 2018

description: In 1990 a gathering of ecopsychologists took place at the Harvard Centre for Psychology and Social Change to participate in a conference entitled “Psychology as if the Whole Earth Mattered”.  They concluded that “if the self is expanded to include the natural world, behavior leading to destruction of this world will be experienced as self-destruction” (Roszak, Gomes, & Kanner, 1995). I take this idea into the realm of science and science education which I suggest requires a reconfiguration and extension of science into a new inter- and trans-disciplinary realm of sustainability science with implications for renewed pedagogies of science in schools and universities. Such a changing perspective requires greater vision, creativity and imaginative approaches to address the problems currently facing the planet and the future of humanity. This paper provides an overview of a journey in science education over the years covering a range of views around science: starting from what we might consider to be the idea of modern science and how that science has been transformed into “big science” and “techno-science”. Further, in the current era of the Anthropocene (Steffen, Crutzen, & McNeill, 2007) it can be argued that such approaches to science need to be reformed to take account of ideas such as post-normal science (Funtowicz & Ravetz, 1994),  sustainability science (Clark & Dickson, 2003) and holistic science (Bohm, 1980; Goodwin, 1997). Using the concepts of planetary boundaries (Rockström et al., 2009b) and doughnut economics (Raworth, 2012, 2017) as a framework, consideration is given to what this might mean for science education futures.

description: In one theory as perceived surprise increases, arousal increases and pleasantness increase up to a point, after which it levels off or decreases. However, studies indicate that for environmental response, arousal and pleasantness are independent of one another. Those studies did not examine movement through spaces. We sought to study response to surprise as experienced in moving between pairs of offices. We created three simulated offices (A, B, and C) and nine virtual walks between each possible pair, such that some walks had no physical differences (AA, BB, and CC), some had moderate physical differences (AB, BA, BC, CB), and some had larger physical differences (AC, CA). A test confirmed that the manipulations worked as planned. To measure arousal and pleasantness, we created two three-item scales (each in English and Italian). We assigned participants in the US (121 adults, 47 men, 84 men) and Italy (67 adults, 343 men, 33 women) at random to either a within-group condition or one of the three between-group conditions (Low Surprise, Medium Surprise, or High Surprise). We used the within group to test the CFA model, and we used the between group conditions to test the effects of surprise. The CFA found the two three-item scales fit the multi-level model well. We combined the items into two three-item scales for the analysis of effects of surprise. Both arousal and pleasantness increased from low to moderate surprise, but decreased from moderate to high surprise. The results suggest value in studying dynamic environmental experience.

An Optimal Truthful Mechanism for the Online Weighted Bipartite Matching Problem
Creators: name: Reiffenhäuser, Rebecca
Publisher: name: arXiv

Subjects: subject: Computer Science and Game Theory (cs.GT)

description: In the weighted bipartite matching problem, the goal is to find a maximum-weight matching in a bipartite graph with nonnegative edge weights. We consider its online version where the first vertex set is known beforehand, but vertices of the second set appear one after another. Vertices of the first set are interpreted as items, and those of the second set as bidders. On arrival, each bidder vertex reveals the weights of all adjacent edges and the algorithm has to decide which of those to add to the matching. We introduce an optimal, $e$-competitive truthful mechanism under the assumption that bidders arrive in random order (secretary model). It has been shown that the upper and lower bound of e for the original secretary problem extends to various other problems even with rich combinatorial structure, one of them being weighted bipartite matching. But truthful mechanisms so far fall short of reasonable competitive ratios once respective algorithms deviate from the original, simple threshold form. The best known mechanism for weighted bipartite matching by Krysta and Vöcking (ICALP 2012) offers only a ratio logarithmic in the number of online vertices. We close this gap, showing that truthfulness does not impose any additional bounds. The proof technique is new in this surrounding, and based on the observation of an independency inherent to the mechanism. The insights provided hereby are interesting in their own right and appear to offer promising tools for other problems, with or without truthfulness.

description: The near-infrared emission from the black hole at the Galactic center (Sgr A*) has unique properties. The most striking feature is a suggestive periodic sub-structure that has been observed in a couple of flares so far. Using near-infrared polarimetric observations and modelling the quasi-periodicity in terms of an orbiting blob, we try to constrain the three dimensional orientation of the Sgr A* system. We report on so far unpublished polarimetric data from 2003. They support the observations of a roughly constant mean polarization angle of 60 degr \pm 20 degr from 2004-2006. Prior investigations of the 2006 data are deepened. In particular, the blob model fits are evaluated such that constraints on the position angle of Sgr A* can be derived. Confidence contours in the position-inclination angle plane are derived. On a 3sigma level the position angle of the equatorial plane normal is in the range 60 degr - 108 degr (east of north) in combination with a large inclination angle. This agrees well with recent independent work in which radio spectral/morphological properties of Sgr A* and X-ray observations, respectively, have been used. However, the quality of the presently available data and the uncertainties in our model bring some ambiguity to our conclusions.

I care (my home)
Creators: name: Marchetti, Chiara
Publisher: name: Università degli Studi di Torino
Year: 2019

description: To the question what is the effect of pro-environmental solutions on the well-being of the individual the answer is that there are different schools of thought in environmental psychology, but all tend to find objective solutions. In my reflection I would like to focus on the subject and its design choices aimed at the well-being of the HOME environment. Currently, attention to wellbeing leads to "green" design choices. But behind the word green different meanings are stratified. We move from Passive house, not necessarily using natural materials; to that Zero Impact with recycled materials, not always high performance; to the biomorphic design where the fruition is often tiring, to Feng Shui increasingly in vogue in the West and finally to the biophilic design. There are different ways to get to the living well, which certainly has objective characteristics, but often ignores the subjective principle of I CARE (MY HOME). I CARE (MY HOME) defines the path to be taken where each design choice is dictated by a different meaning that the subject attributes to it. In this sense, one's home becomes regenerative and creates well-being. A domestic environment without subjective meaning simply becomes a beautiful environment. Considering the objective parameters what creates the ideal environment? Space? Shape? Distribution? Natural materials use? What is more regenerative? The window on a real park or a poster with a coniferous forest or a poster of an Arizona desert? The conclusion is that although a house is "objectively correct" to be "perfect" it must be empathic with those who experience it.

description: Collimated beam ultrasound systems are a novel technology for imaging inside multi-layered structures such as geothermal wells. Such systems include a transmitter and multiple receivers to capture reflected signals. Common algorithms for ultrasound reconstruction use delay-and-sum (DAS) approaches; these have low computational complexity but produce inaccurate images in the presence of complex structures and specialized geometries such as collimated beams. In this paper, we propose a multi-layer, ultrasonic, model-based iterative reconstruction algorithm designed for collimated beam systems. We introduce a physics-based forward model to accurately account for the propagation of a collimated ultrasonic beam in multi-layer media and describe an efficient implementation using binary search. We model direct arrival signals, detector noise, and a spatially varying image prior, then cast the reconstruction as a maximum a posteriori estimation problem. Using simulated and experimental data we obtain significantly fewer artifacts relative to DAS while running in near real time using commodity compute resources.

description: The influences of the leader in a group of V flight formation are dealt with. The investigation is focused on the effect of its position and shape on aerodynamics performances of a given V flight formation. Vortices generated the wing tip of the leader moves downstream forming a pair of opposite rotating line vortices. These vortices are generally undesirable because they create a downwash that increases the induced drag on leaders wing. However, this downwash is also accompanied by an upwash that can beneficial to the followers wing flying behind the leaders one, namely a favorable lift for the followers wing. How much contributions of the leaders wing to the followers wing in the V formation flight is determined by the strength of tip vortices generated by the leaders wing which is influenced by its position and shape including incidence angle, dihedral angle, aspect ratio and taper ratio. The prediction of aerodynamic performances of the V flight formation including lift, drag and moment coefficients is numerically performed by solving Navier Stokes equations with k e turbulence model. The computational domain is defined with multiblock topology to capture the complex geometry arrangement of the V flight formation.

Publisher: name: Università degli Studi di Torino
Year: 2019

description: The new urban question has been convoyed by the abrupt inequity of income distribution; environmental disasters; demographic shrinkage; inner asymmetries in urban communities; rising of informal markets; and city voids. Brownfields, abandoned buildings and vacant lands are unresolved environmental and social problems in many European cities. These ruins are the physical manifestation of our postindustrial landscape. Urban deprived areas demand urgent adaptive game plans. How can these gaps become instruments of wellness whilst open to regenerative/restorative social innovations?

DOT TO DOT© www.dots.scot is a cross-disciplinary ecosystem that enables intergenerational groups from creative local community - social entrepreneurs, researchers, educators and youth- to fill and reuse ecologically empty sites on a temporary basis and to improve life of disadvantaged communities by remaking with waste through regenerative designs and live projects. It is both a real and digital live community project.

DOT TO DOT© is a social innovation project funded by EU ESF Aspiring Communities programme in Glasgow, Scotland (2017-2018). It addresses up-to-date urban regeneration and health issues from local perspectives providing a vivid community-led development approach. It proposes a new conceptual framework for considering the driving and interconnected factors to tackle health and wellbeing in selected deprived areas. Its sensory dimension is an experimental site - community touchpoint- which is planned in three distinctive areas: (a) the Community Garden, an edible garden (phase 1); (b) the Remake Station (phase 2) and (c) the sensory woodland.

The DOT TO DOT© methodology employs somatic learning tools; research by doing; experimentation by reusing; and collaborative design modelling methods, integrating various sources and types of data including spatial, visual, quantitative and qualitative data. It includes sensory, physical and digital engagements with urban communities in the process of creating and transferring knowledge.

Furthermore, it aims at generating knowledge exchange and providing live demonstrations that is relevant to the local community development for improving integrated decision making and bottom-up governance for healthy and wellbeing outdoor environments.

description: Current models of Titan ionosphere have difficulties in explaining the observed electron density and/or temperature. In order to get new insights, we re-analyzed the data taken in the ionosphere of Titan by the Cassini Langmuir probe (LP), part of the Radio and Plasma Wave Science (RPWS) instrument. This is the first of two papers that present the new analysis method (current paper) and statistics on the whole dataset. We suggest that between 2 and 4 electron populations are necessary to fit the data. Each population is defined by a potential, an electron density and an electron temperature and is easily visualized by a dinstinct peak in the second derivative of the electron current, which is physically related to the electron energy distribution function (Druyvesteyn method). The detected populations vary with solar illumination and altitude. We suggest that the 4 electron populations are due to photo-ionization, magnetospheric particles, dusty plasma and electron emission from the probe boom, respectively.

description: To bring local identity into material culture – into the design of buildings, interiors and products – is a part of socio-cultural well-being and social sustainability. In the contemporary era of globalisation and unification in material culture, it is very important to maintain and apply elements and concepts that are special and unique for single localities and regions. Cultural identity and tradition are inseparable parts of every society and can influence the character of a local built-environment and its elements. This “DNA” of society indirectly affects the typology/morphology and semiotics of crafted products and architecture, and it creates the basics of the design language of a country or region. Local identity can be understood as the essence of a cultural heritage and genius loci and plays a very important part in self-identification. This is unfortunately very often misinterpreted in the design of contemporary building or products. Although there exist many research studies in the field of ethnography, cultural anthropology, history and archaeology, they are very rarely available and understandable for architects, designers, investors, producers and services providers directly in the regions. Preserving local identity is also a big challenge for local industry and eco-tourism. The last part of the study is questioning the ways of working with “the known” and shows some examples from Europe and Slovakia.
After an evaluation of the relation between regional identity and wellbeing, we have set four main issues dealing with local identity as reflected in material culture that contribute to the well-being of users during all kind of interactions with built environment, and these are: attachment to place –building a self- and social group identity; comfort from interaction with “the known” – shared cultural values and signs, archetypes, and stereotypes; authentic experience and satisfaction through one’s own hands-on experience and interaction with handcrafted objects. Together with the phenomena of local self identity, they are explored further on in the paper. The paper also shows the first results of the project - IDENTITY.SK – a common platform of design, architecture and the social sciences in the form of regional concepts for products and services, coming from interdisciplinary literature and field research and storytelling.

description: In this paper, a novel machine learning regression based single event transient (SET) modeling method is proposed. The proposed method can obtain a reasonable and accurate model without considering the complex physical mechanism. We got plenty of SET current data of SMIC 130nm bulk CMOS by TCAD simulation under different conditions (e.g. different LET and different drain bias voltage). A multilayer feedfordward neural network is used to build the SET pulse current model by learning the data from TCAD simulation. The proposed model is validated with the simulation results from TCAD simulation. The trained SET pulse current model is implemented as a Verilog-A current source in the Cadence Spectre circuit simulator and an inverter with five fan-outs is used to show the practicability and reasonableness of the proposed SET pulse current model for circuit-level single-event effect (SEE) simulation.

description: While there are benefits to urbanization, deviations from a rural lifestyle can pose an issue for psychological well-being, as there is limited access to restorative environments (e.g., nature; van den Berg, Hartig, & Staats, 2007). Given these concerns associated with increased urbanization, how can we implement components of restorative environments into urban settings? Towards that end, an understanding of the attributes of restorative environments is needed.            Attention Restoration Theory (ART; Kaplan, 1995) is the predominant theory identifying characteristics of nature that are thought to make it restorative. Albeit, these characteristics lack operational definitions, thus generating several methodological challenges in critically assessing ART. For example, a major component of restoration within the ART framework is soft fascination, which is an involuntary capturing of attention, but not in a dramatic fashion. However, there is no empirical support of nature’s ability to innately hold attention, and this poor understanding contributes to the challenges in developing an operational definition of soft fascination. We describe attributes of stimuli that are known to capture visual attention (e.g., salience; Ruz & Lupiáñez, 2002) and consider whether such attributes are consistent with the notion of soft fascination. Since ART evolved from literature on aesthetics and environmental preferences (e.g., Kaplan, 1987), a review of this literature may inspire new ways to define restorative characteristics of nature, and thereby, promote the implementation of these characteristics into built environments. Thus, the purpose of this paper is to integrate relevant literature from multiple subfields of psychology to inspire research that can employ new methodology and ultimately better our understanding of the mechanisms underlying restorative environments.

description: The Cumulative Risk Model (CRM) has usually been applied to developmental and quality of life psychology; however, the CRM could also be applied to the urban safety and personal well-being of people living in urban environments, since cities are complex, multi-risk scenarios. This paper presents two studies meant to provide evidence in support of this hypothesis. The first study (N=287) was aimed to create and validate a set of scales to measure the cumulative risk index and to pilot study two. Study two (N = 540), instead, aimed at showing how a higher number of risk factors is associated to a higher level of perception of insecurity/fear of crime and a smaller level of wellbeing/satisfaction with life and provided consistent correlational evidence, controlling for the neighborhood effect. These studies showed that the CRM can be used to study urban safety issues, since perception of personal safety, fear of crime and well-being are multidimensional constructs, and are affected by a large series of environmental and psychosocial risk factors. The CRM could have significant applications for policymaking and urban renovation.

description: The ionosphere of Titan hosts a complex ion chemistry leading to the formation of organic dust below 1200 km. Current models cannot fully explain the observed electron temperature in this dusty environment. To achieve new insight, we have re-analyzed the data taken in the ionosphere of Titan by the Cassini Langmuir probe (LP), part of the Radio and Plasma Wave Science package. A first paper (Chatain et al., 2021) introduces the new analysis method and discusses the identification of 4 electron populations produced by different ionization mechanisms. In this second paper, we present a statistical study of the whole LP dataset below 1200 km which gives clues on the origin of the 4 populations. One small population is attributed to photo- or secondary electrons emitted from the surface of the probe boom. A second population is systematically observed, at a constant density (~500 cm-3), and is attributed to background thermalized electrons from the ionization process of precipitating particles fom the surrounding magnetosphere. The two last populations increase in density with pressure, solar illumination and EUV flux. The third population is observed with varying densities at all altitudes and solar zenith angles except on the far nightside (SZA > ~140°), with a maximum density of 2700 cm-3. It is therefore certainly related to the photo-ionization of the atmospheric molecules. Finally, a fourth population detected only on the dayside and below 1200 km reaching up to 2000 cm-3 could be photo- or thermo-emitted from dust grains.

description: We have studied Ni-substitution effect in LaFe$_{1-x}$Ni$_{x}$AsO ($0\leq x \leq0.1$) by the measurements of x-ray diffraction, electrical resistivity, magnetic susceptibility, and heat capacity. The nickel doping drastically suppresses the resistivity anomaly associated with spin-density-wave ordering in the parent compound. Superconductivity emerges in a narrow region of $0.03\leq x \leq0.06$ with the maximum $T_c$ of 6.5 K at $x$=0.04, where enhanced magnetic susceptibility shows up. The upper critical field at zero temperature is estimated to exceed the Pauli paramagnetic limit. The much lowered $T_c$ in comparison with LaFeAsO$_{1-x}$F$_{x}$ system is discussed.

description: TeVeS, a relativistic theory of gravity, was designed to provide a basis for the modified Newtonian dynamics. Since TeVeS differs from general relativity (e.g., it has two metrics, an Einstein metric and a physical metric), black hole solutions of it would be valuable for a number of endeavors ranging from astrophysical modeling to investigations into the interrelation between gravity and thermodynamics. Giannios has recently found a TeVeS analogue of the Schwarzschild black hole solution. We proceed further with the program by analytically solving the TeVeS equations for a static spherically symmetric and asymptotically flat system of electromagnetic and gravity fields. We show that one solution is provided by the Reissner-Nordstrom metric as physical metric, the TeVeS vector field pointing in the time direction, and a TeVeS scalar field positive everywhere (the last feature protects from superluminal propagation of disturbances in the fields). We work out black hole thermodynamics in TeVeS using the physical metric; black hole entropy, temperature and electric potential turn out to be identical to those in general relativity. We find it inconsistent to base thermodynamics on the Einstein metric. In light of this we reconsider the Dubovsky-Sibiryakov scenario for violating the second law of thermodynamics in theories with Lorentz symmetry violation.
