description: Microbiome diversities in soilless rhizospheres are becoming known as an important factor for urban agriculture and food security. Plant pathogens like Pythium are common in hydroponic systems, but symptoms can be prevented with an established rhizo-microbiome. This study explored the microbiome within a single greenhouse to compare the dominant microorganisms in different systems and crops. Petri dishes were sterilized by soaking in 16% sodium hypochlorite and then isopropyl alcohol (70%). Potato dextrose agar (PDA) was inoculated with six samples; vermicompost castings, liquid mycorrhizal Orca (Plant Revolution Inc.), surface sterilized roots from a rotting Kalanchoe sp. in soil, an aquaponic Fragaria x ananassa, hydroponic Ocimum basilicum, and Lactuca sativa. After 5 days of incubation, the plates showed a few types of colonies (1-6 organisms per dish), with many single organisms consuming the entire dish. The vermicompost castings had the greatest number of species compared to the other samples (p-value= 0.0426). Unknown microbes were stained with methylene blue dye and observed at 1000x magnification. Results showed that a rod-shaped, gram-positive bacteria was dominant in most dishes, and produced white to beige colonies with undulated edges and wrinkles around the center, suggesting its identification as Bacillus subtilis. Two distinct species grew on the agar from the Kalanchoe sp. root, and a zone of inhibition formed between them. Covering the majority of the agar was a white fuzz, presumed to be a pathogenic Pythium sp., except for a cm wide halo around a single bacterial colony, which appeared to be B. subtilis. This study indicates that B. subtilis can produce inhibitory effects on phytopathogens like Pythium. Further investigations should focus on isolating and identifying the strains of B. subtilis and Pythium from root samples and testing for inhibitory effects with petri dishes and live plants. Future trials can help determine if rhizo-microbiomes that contain organisms like B. subtilis prevent pathogens like Pythium from infecting roots.

description: The use of finite harmonic oscillator spaces in many-body calculations introduces both infrared (IR) and ultraviolet (UV) errors. The IR effects are well approximated by imposing a hard-wall boundary condition at a properly identified radius L_eff. We show that duality of the oscillator implies that the UV effects are equally well described by imposing a sharp momentum cutoff at a momentum Lambda_eff complementary to L_eff. By considering two-body systems with separable potentials, we show that the UV energy corrections depend on details of the potential, in contrast to the IR energy corrections, which depend only on the S-matrix. An adaptation of the separable treatment to more general interactions is developed and applied to model potentials as well as to the deuteron with realistic potentials. The previous success with a simple phenomenological form for the UV error is also explained. Possibilities for controlled extrapolations for A > 2 based on scaling arguments are discussed.

title: Ora et labora - eine gesundheitssoziologische Studie über die Lebenszufriedenheit von älteren Ordensleuten in Österreich im Kontext von lebenslangem Arbeiten
Creators: name: Krivanek, Desiree
Year: 2021

description: Die Dissertation befasst sich mit der Lebenszufriedenheit von älteren Ordensleuten im Kontext vom lebenslangen Arbeiten. Im Gegensatz zur weltlichen Bevölkerungen findet im Orden keine Pensionierung statt, weshalb Ordensfrauen und Ordensmänner bis zum Tode aktiv tätig bleiben. Welche Bedingungen im Orden eine Anpassung an den Alterungsprozess ermöglichen und inwiefern dadurch eine „erfolgreiche Alterung“ stattfindet, wurde anhand des Lebenslaufes von älteren Ordensfrauen und Ordensmänner in Österreich qualitativ untersucht. Die Ergebnisse der episodischen Interviews sowie den empirischen Beobachtungen verdeutlichen, dass durch ein komplexes Zusammenspiel von Religion, Arbeit und Gemeinschaft die übernommenen Aufgaben von den Ordensmitgliedern als sinnerfüllend wahrgenommen werden und einen ausgeglichenen Lebensrhythmus schaffen. Trotz oder gerade durch die traditionellen Norm- und Wertvorstellungen, stellt die Ordenspopulation eine moderne Gesellschaftsform dar, die Riley (Riley et al. 1999) als „altersintegrierende Gesellschaft“ definieren würde: Arbeit, Bildung und Freizeit verlaufen während des gesamten Lebenslaufes parallel. Nicht die Altersgrenze, sondern die Gesundheitsgrenze bestimmt den Lebenslauf der Ordensgemeinschaft und trägt zu einer erfüllenden Alterung bei. Dadurch kann auf struktureller Ebene eine alternde Gesellschaft weiterhin bestehen sowie auf individueller Ebene eine Lebenszufriedenheit im Alter erreicht werden.

description: This research investigates the potential of digital therapeutics, particularly serious games and gamification, as effective tools for treating addiction. Addictive disorders significantly disrupt the brain's reward system, resulting in severe and lasting consequences, making them a prevalent issue in our world. Serious games and gamification have emerged as innovative approaches that harness engaging gameplay to simulate real-world scenarios, empowering users to confront addictive behaviors within a controlled environment. By integrating game elements into non-gaming contexts, addiction treatment becomes increasingly enjoyable and motivating for users, fostering a more gratifying therapeutic experience. While examining the potential benefits and limitations of employing digital therapeutics for addiction treatment, this research conducts a comprehensive review of existing literature and case studies to abide by NIH's treatment standards. Additionally, it explores the role of data analytics and artificial intelligence in addressing the lack of personalized treatment interventions and emotional support within existing gamified approaches. The findings emphasize the importance of integrating digital therapeutics into traditional treatment modalities to enhance overall outcomes for individuals battling addiction. By harnessing the power of modern technologies like serious games and gamification, healthcare professionals can offer more accessible, scalable, and effective addiction treatment solutions in the digital age.

description: We investigate the achievable efficiency of both the time and the space discretisation methods used in Antares for mixed parabolic-hyperbolic problems. We show that the fifth order variant of WENO combined with a second order Runge-Kutta scheme is not only more accurate than standard first and second order schemes, but also more efficient taking the computation time into account. Then, we calculate the error decay rates of WENO with several explicit Runge-Kutta schemes for advective and diffusive problems with smooth and non-smooth initial conditions. With this data, we estimate the computational costs of three-dimensional simulations of stellar surface convection and show that SSP RK(3,2) is the most efficient scheme considered in this comparison.

description: Two-dimensional (2D) materials with high carrier mobility and tunable magnetism are in high demand for nanoelectronics and spintronic applications. Herein, we predict a novel two-dimensional monolayer KTlO that possesses an indirect band gap of 2.25 eV (based on HSE06) and high carrier mobility (1860 $\mathrm{cm^2\ V^{-1}s^{-1}}$ for electron and 2540 $\mathrm{cm^2\ V^{-1}s^{-1}}$ for hole) by means of ab initio calculations. KTlO monolayer has a calculated cleavage energy of 0.56 $\mathrm{J\ m^{-2}}$, which suggests exfoliation of bulk material as viable means for the preparation of mono- and few-layer materials. Remarkably, the KTlO monolayer suggests tunable magnetism and half-metallicity with hole doping, which are attributed to the novel Mexican-hat-like bands and van Hove singularities in its electron structure. Furthermore, monolayer KTlO exhibits moderate optical absorption over visible light and ultraviolet region. The band gap value and band characteristics of monolayer KTlO can be strongly manipulated by biaxial and uniaxial strains to meet the requirements of various applications. All these novel properties render monolayer KTlO a promising functional material for future nanoelectronics and spintronic applications.

description: Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with at least two hadronically decaying tau leptons, missing transverse momentum and low jet activity. The analysis is based on an integrated luminosity of 20.3 fb$^{-1}$ of proton--proton collisions at $\sqrt{s}=8$ TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excess is observed with respect to the predictions from Standard Model processes. Limits are set at 95% confidence level on the masses of the lighter chargino and next-to-lightest neutralino for various hypotheses for the lightest neutralino mass in simplified models. In the scenario of direct production of chargino pairs, with each chargino decaying into the lightest neutralino via an intermediate tau slepton, chargino masses up to 345 GeV are excluded for a massless lightest neutralino. For associated production of mass-degenerate charginos and next-to-lightest neutralinos, both decaying into the lightest neutralino via an intermediate tau slepton, masses up to 410 GeV are excluded for a massless lightest neutralino.

description: Two-dimensional materials with a proper band gap and high carrier mobility are urgently desired in the field of nanoelectronics. We propose a novel two-dimensional crystal monolayer $\mathrm{TlP_5}$, which is dynamically and thermodynamically stable and possesses a direct band gap of 2.02 eV with high carrier mobilities (13960 $\mathrm{cm^2\ V^{-1}s^{-1}}$ for electrons and 7560 $\mathrm{cm^2\ V^{-1}s^{-1}}$ for holes), comparable to that of phosphorene. The band gap value and band characteristics of monolayer $\mathrm{TlP_5}$ can be adjusted by biaxial and uniaxial strains, and excellent optical absorption over the visible-light range is predicted. These properties, especially for the balanced high mobilities for not only the electrons but also the holes, render monolayer $\mathrm{TlP_5}$ an exciting functional material for future nanoelectronics and optoelectronic applications.

description: Accessibility issues persistently limit access and usability of apps for individuals with diverse needs. Developers often struggle to determine the accessibility of their designs, encountering challenges in identifying and addressing potential barriers, especially with numerous disabilities such as motor impairment and visual impairment. Many tools and indicators have been created to test the implementation for accessibility issues. However, there is little support in the design process to ensure that software engineers have user-friendly designs prior to implementation and testing. We present a Graphical User Interface (GUI)-based search engine that allows developers to compare a screenshot of their preliminary designs of their Android app with a set of similar screenshots in accessibility scores using a variety of tests. This allows developers to ensure their designs are accessible before spending significant time implementing and testing them. By offering developers a tool to find similar yet more accessible designs, we hope to guide the design of accessible apps before implementation and testing, improving accessibility in apps with less effort and time spent by the developer.

description: A simple relation between inhomogeneous transfer matrices and boundary quantum KZ equations is exhibited for quantum integrable systems with reflecting boundary conditions, analogous to an observation by Gaudin for periodic systems. Thus the boundary quantum KZ equations receive a new motivation.

description: Bug reporting serves as an integral resource for software maintenance by providing detailed information about issues within an app. However, user-submitted bug reports often lack adequately detailed reproduction steps for developers, prompting the need for a tool that makes use of app information to assist reporters in generating improved bug reports. Furthermore, with tools based on large language models (LLMs) such as ChatGPT on the rise, this project aims to better understand how LLMs can assist end-users in the bug reporting process and develop a tool that leverages LLMs to automatically rewrite low-quality bug reports to contain more detailed and complete information. To help assist LLMs in “comprehending” app interfaces, we developed a system that automatically extracts and formats information such as GUI components and descriptions of app functionality for ChatGPT. Our tool constructs an app execution model using tools for automatically exploring and recording interactions with app UIs and prompts an LLM using chain-of-thought reasoning and few-shot learning to predict reproduction steps. We are currently working to evaluate the efficacy of our tool in improving low-quality bug reports using open-source benchmarks from the research community.

Magnetic phase diagram slightly below the saturation field in the stacked $J_1$-$J_2$ model in the square lattice with the $J_{\text{C}}$ interlayer coupling

description: We study the effect of adding interlayer coupling to the square lattice, $J_1$-$J_2$ Heisenberg model in high external magnetic field. In particular, we consider a cubic lattice formed from stacked $J_1$-$J_2$ layers, with interlayer exchange coupling $J_{\text{C}}$. For the 2-dimensional model ($J_{\text{C}}=0$) it has been shown that a spin-nematic phase appears close to the saturation magnetic field for the parameter range $-0.4 \lesssim J_2/J_1$ and $J_2>0$. We determine the phase diagram for 3-dimensional model at high magnetic field by representing spin flips out of the saturated state as bosons, considering the dilute boson limit and using the Bethe-Salpeter equation to determine the first instability of the saturated paramagnet. Close to the highly frustrated point $J_2/J_1\sim0.5$, we find that the spin-nematic state is stable even for $|J_{\text{C}}/J_1|\sim 1$. For larger values of $J_2/J_1$, interlayer coupling favors a broad, phase-separated region. Further increase of $|J_{\text{C}}|$ stabilizes a collinear antiferromagnet, which is selected via the order-by-disorder mechanism.

description: Highly-efficient water splitting based on solar energy is one of the most attractive research focuses in the energy field. Searching for more candidate photocatalysts that can work under visible-light irradiation are highly demanded. Herein, using first principle calculations based on density functional theory, we predict that the two dimensional silicon chalcogenides, i.e. SiX (X=S, Se, Te) monolayers, as semiconductors with 2.43 eV~3.00 eV band gaps, exhibit favorable band edge positions for photocatalytic water splitting. The optical adsorption spectra demonstrate that the SiX monolayers have pronounced optical absorption in the visible light region. Moreover, the band gaps and band edge positions of silicon chalcogenides monolayers can be tuned by applying biaxial strain or increasing the number of layers, in order to better fit the redox potentials of water. The combined novel electronic, high carrier mobility, and optical properties render the two dimensional SiX a promising photocatalyst for water splitting.

description: The objective of the project was to develop sodium-ion batteries (SIBs), with stable life cycles. The materials used in this study are affordable and abundant as well, making the SIBs more cost-effective and sustainable. The advantages of affordable rechargeable batteries with long and stable life cycles are having more resources to make these kinds of batteries, along with the durability against time. The first step of my research was synthesizing tetrahydroxy-1,4-benzoquinone to fabricate the electrodes used in the batteries, by mixing it with carbon black and sodium alginate aqueous solution. After assembly of the batteries in the glovebox, various electrochemical methods were used to test the performances of the anode, such as galvanostatic charge and discharge tests to study the life cycles of the batteries, as well as the decay during repeated charge and discharge processes, aiming to achieve long lifetime in SIBs. The research showed that using the active material we synthesized gives the batteries stable life cycles, as well as no deterioration in the composition of the anode. Batteries such as these will improve technology in the future and allow people to have more durable everyday items at a lower cost.

description: Searching for materials with single atom-thin as well as planar structure, like graphene and borophene, is one of the most attractive themes in two dimensional materials. Herein, using density functional theory calculations, we have proposed a series of single layer planar penta-transition metal phosphide and arsenide, i.e. TM$\mathrm{_2}$X$\mathrm{_4}$ (TM= Ni, Pd and Pt; X=P, As). According to the calculated phonon dispersion relation and elastic constants, as well as ab initio molecular dynamics simulation results, monolayers of planar penta-TM$\mathrm{_2}$X$\mathrm{_4}$ are dynamically, mechanically, and thermally stable. In addition, the band structures calculated with the screened HSE06 hybrid functional including spin-orbit coupling show that these monolayers are direct-gap semiconductors with sizeable band gaps ranging from 0.14 eV to 0.69 eV. Besides, the optical properties in these monolayers are further investigated, where strong in-plane optical absorption with wide spectral range has been revealed. Our results indicate that planar penta-TM$\mathrm{_2}$X$\mathrm{_4}$ monolayers are interesting narrow gap semiconductors with excellent optical properties, and may find potential applications in photoelectronics.

description: Lithium-ion batteries (LIBs) have been considered the most promising energy storage devices for various applications in portable electronics, electric transportations, and grid-scale storage systems. However, the inorganic cathode materials used in commercial LIBs cannot meet the urge to design high-performance sustainable electrode materials for next-generation rechargeable batteries. Organic electrode materials (OEMs) featuring low-cost, lightweight, and diverse chemical structures not only offer high theoretical capacity and stable cycling performance but also are safe for the environment. In this work, we designed and tested a carbonyl-based polyimide as an organic cathode in LIBs. The electrochemical performance of the polymer cathode has been investigated by several techniques such as cyclic voltammetry and galvanostatic charge-discharge tests. The carbonyl groups on the naphthalene backbone undergo a multi-electron reversible redox reaction delivering high redox potential, long cycling capability, and robust reaction kinetics. Post-cycling characterizations demonstrated high stability in the morphology and chemical structure of the electrodes upon cycling. Our results suggest that developing redox-active polymers with extended conjugation structures can be a practical approach to achieving sustainability for rechargeable batteries.

description: Aufgrund einer immer länger dauernden Ausbildung und der medizinischen Möglichkeiten erst spät Mutter zu werden, entscheiden sich viele Frauen für eine späte erste Geburt. Dies bringt aber ein erhöhtes Risiko für eine mögliche geistige oder entwicklungsbedingte Beeinträchtigung beim Kind, mit sich. Im Rahmen dieser Studie wird der Einfluss einer komorbiden Austismus-Spektrums-Störung (ASS) bei Kindern und Jugendlichen mit Trisomie 21 (T21), über die adaptiven Verhaltensweisen auf die wahrgenommene Belastung der Eltern, untersucht. In der laufenden, größeren Trisomie 21 - Outcome Studie (TriO), wird der kognitive und emotionale Entwicklungsstatus von 6 bis 16-Jährigen mit einer T21 detailliert erhoben. Die Ergebnisse der Studie sind besonders relevant für eine frühe Erkennung und Beratung bezüglich Förderung der betroffenen Kinder und möglicher auftretender Belastungen der Eltern. Ein signifikanter Zusammenhang von adaptivem Verhalten der Kinder und Jugendlichen mit einer T21 auf die wahrgenommenen Belastung der Eltern konnte festgestellt werden. Da die Prävalenz einer komorbiden Störung in der T21-Population wesentlich höher ist, als in der Allgemeinbevölkerung, wurde überprüft ob eine zusätzlich vorliegende ASS einen Einfluss auf die elterliche Belastung hat. Hier konnte festgestellt werden, dass die Eltern signifikant höher belastet waren, wenn ihre Kinder von einer zusätzlichen ASS betroffen waren. Es wurde angenommen, dass die erhöhte Belastung durch die schwachen adaptiven Fähigkeiten der T21- Kinder mit ASS bedingt ist. Hier ergab die Analyse, dass der Einfluss einer ASS auf die Elternbelastung durch die adaptiven Fähigkeiten der Kinder und Jugendlichen partiell mediiert wird. Ein Rest an Varianz konnte jedoch nicht erklärt werden und bedarf weiterer Forschung. Mögliche Alternativerklärungen werden diskutiert.

Perylenetetracarboxylic dianhydride (PTCDA), a semiconductor material with a highly conjugated system and four carbonyl groups, still lacks a comprehensive understanding of its potential as an organic cathode material. Here, PTCDA was chosen because a more conjugated system offers greater stability in the reduction-oxidation process. In our study, the viability of PTCDA as an active material in lithium-ion and sodium-ion batteries was investigated. Initial testing with lithium-ion and sodium-ion batteries showed high compatibility between PTCDA and sodium alginate (SA), but with low stability, so a small amount of graphene was introduced into the cathode to improve the cyclic stability. Our study shows that PTCDA is a better active material in sodium-ion batteries than lithium-ion batteries. This is important because of the rising cost of lithium battery production. Our research presents a cost-effective and sustainable alternative to lithium-ion batteries.

title: Stil und Ethik im Alpinismus
Creators: name: Kuncic, David
Year: 2021

description: Als Kulturgut ist der Alpinismus in erster Linie von der Zeit geprägt, in der er praktiziert wird. Über die letzten Jahrhunderte haben sich im Klettern und Bergsteigen völlig unter-schiedliche Begehungsstile entwickelt, die maßgeblich vom zeitgeschichtlichen Kontext ihrer Entstehung geprägt sind. Heute wird Alpinismus in seinen unterschiedlichen Betäti-gungsfeldern vor allem als Sport verstanden. Doch die Auseinandersetzung des Menschen mit dem Berg kennt kein fixiertes Regelwerk. Diese Besonderheit stellt den Ausgangspunkt dieser Arbeit dar. Durch das Fehlen allgemein gültiger Regeln hat sich ein umfassender al-pin-ethischer Diskurs konstituiert, in dem Stil- und Wertefragen des Kulturguts thematisiert werden. Geführt wird dieser Diskurs weitgehend von professionellen BergsteigerInnen, die als Autoritäten bestehende Streitfragen bearbeiten und dadurch eine allgemein anerkannte Ethik etablieren wollen. Die Texte, die innerhalb dieser Arbeit untersucht werden, sind dem-nach stark von Argumentation geprägt. Diese Argumentation steht im Mittelpunkt dieser sprachwissenschaftlichen Arbeit, die durch die Anwendung diskurslinguistischer Methoden die kulturelle Signifikanz dieser Texte herausarbeiten will. Neben einer umfassenden Argu-mentationsanalyse, die auf mehreren sprachlichen Ebenen vorgenommen wird, widmet sich die vorliegende Arbeit auch der Frage, wie die untersuchten Texte das Kulturgut Alpinismus prägen.

description: In this paper we compute general-relativistic polytropic models simulating rigidly rotating, pulsating neutron stars. These relativistic compact objects, with a radius of $\sim 10 \, \mathrm{km}$ and mass between $\sim 1.4$ and $3.2$ solar masses, are closely related to pulsars. We emphasize on computing the change in the pulsation eigenfrequencies owing to a rigid rotation, which, in turn, is a decisive issue for studying stability of such objects. In our computations, we keep rotational perturbation terms of up to second order in the angular velocity.

description: We study the quark spectrum at nonzero temperature and density near the critical point (CP) of the chiral phase transition incorporating effects of the scalar- and pseudoscalar-density fluctuations in a chiral effective model with a nonzero current quark mass. It is known that the soft mode associated with the second-order transition at the CP lies in the spacelike region of the scalar-density fluctuation. We find that the soft mode influences the quark spectrum significantly near the CP, resulting in the shift of the quasiquark peak. Effects of the composite stable pions on the quark spectrum near the CP are also discussed.

description: The network of cosmic strings generated in a phase transition during inflation enters the scaling regime later than that of usual strings. If it occurs after the recombination, temperature anisotropies of the cosmic microwave background (CMB) at high multipole moments are significantly reduced. In this paper, we study such effects qualitatively and show that the constraint on the cosmic string tension from the CMB temperature anisotropies and B-mode polarizations can be relaxed. It is shown to be difficult to explain the recent BICEP2 and POLARBEAR results in terms of signals induced by cosmic strings alone even if we take into account the delayed scaling. However, the inflationary tensor-to-scalar ratio required to explain the observed B-mode signals can be slightly reduced to be consistent with the Planck constraint.

Ab initio simulation of $\mathrm{Ta_2O_5}$: A high symmetry ground state phase with application to interface calculation

description: We suggest a tetragonal $I4_1/amd$ phase ($η$-phase) as the ground state of $\mathrm{Ta_2O_5}$ at zero temperature, which is a high symmetry version of the triclinic $γ$-phase $\mathrm{Ta_2O_5}$ predicted by Yang and Kawazoe. Our calculation shows that $γ$-phase $\mathrm{Ta_2O_5}$ will automatically be transformed into the $η$-phase during structural relaxation. Phonon dispersion confirms that the $η$-phase is dynamically stable, while the high temperature $α$-phase $\mathrm{Ta_2O_5}$, which also has the $I4_1/amd$ symmetry, is unstable at zero temperature. A thorough energy comparison of the $β_{AL}$, $δ$, $λ$, $\mathrm{B}$, $\mathrm{L_{SR}}$, $β_R$, $Pm$, $Cmmm$, $γ$, $η$ and $α$ phases of $\mathrm{Ta_2O_5}$ is carried out. The GGA-1/2 method is applied in calculating the electronic structure of various phases, where the $η$-phase demonstrates a 4.24 eV indirect band gap, close to experimental value. The high symmetry tetragonal phase together with computationally efficient GGA-1/2 method greatly facilitate the $ab\ initio$ simulation of $\mathrm{Ta_2O_5}$-based devices. As an example, we have explicitly shown the Ohmic contact nature between metal Ta and $\mathrm{Ta_2O_5}$ by calculating an interface model of $b.c.c.$ Ta and $η$-$\mathrm{Ta_2O_5}$, using GGA-1/2.

The Hydrosocial Cycle approach to deepen on socio ecological systems analysis and water management

description: Balancing socio-ecological systems among competing water demands is a difficult and complex task. Traditional approaches based on limited, linear growth optimization strategies overseen by command/control have partially failed to account for the inherent unpredictability and irreducible uncertainty affecting most water systems due to climate change. Governments and managers are
 increasingly faced with understanding driving-factors of major change processes affecting multifunctional systems. In the last decades, the shift to address the integrated management of water resources from a technocratic ‘‘top-down’’ to a more integrated ‘‘bottom-up’’ and participatory approach was motivated by the awareness that water challenges require integrated solutions and a socially legitimate planning process. Assuming water flows as physical, social, political, and symbolic matters, it is necessary to entwining these domains in specific configurations, in which key stakeholders and decision-makers could directly interact through
 social-learning. The literature on integrated water resources management highlights two important factors to achieve this goal: to deepen stakeholders’ perception and to ensure their participation as a mechanism of co-production of knowledge. Stakeholder Analysis and Governance Modelling approaches are providing useful knowledge about how to integrate social learning
 in water management, making the invisible, visible. The first one aims to identify and categorize stakeholders according to competing water demands, while the second one determines interactions, synergies, overlapping discourses, expectations, and influences between stakeholders, including power-relationships. The Hydro Social Cycle (HSC) analysis combines both approaches as a framework to reinforce integrated water management by focusing on stakeholder analysis and collaborative governance. This method considers that water and society are (re)making each other so the nature and competing objectives of stakeholders involved in complex water systems may affect its sustainability and management. Using data collected from a qualitative questionnaire and applying descriptive statistics and matrices, the HSC deepens on interests, expectations, and power-influence relationships between stakeholders by addressing six main issues affecting decision-making processes: relevance, representativeness, recognition,
 performance, knowledge, and collaboration. The aim of this contribution is to outline this method from both theory and practice perspective by highlighting the benefits of including social sciences approaches in transdisciplinary research collaborations when testing water management strategies affecting competing and dynamic water systems.

Systematic analysis of bone morphogenetic protein signal diversification across Drosophila species during oogenesis
Creators: name: Niepielko, Matthew Gene
Publisher: name: No Publisher Supplied

description: Eggshells of Drosophila species provide great examples of morphological variation. The eggshell is a three-dimensional structure that protects the developing embryo from the surrounding environment and allows continuous gas exchange via tube-like structures called dorsal appendages (DAs). The number, size, shape, and positions of DAs vary among Drosophila species. During animal development, a handful of signaling pathways control tissue differentiation and morphogenesis. In general, mechanisms governing signal diversification that guide morphological variation remain largely unexplored. One conserved signaling pathway involved in guiding tissue development during Drosophila oogenesis is the Bone Morphogenetic Protein (BMP) signaling pathway. Representing a variety of eggshell morphologies, 16 Drosophila species were screened for diversity in BMP signaling during oogenesis. During early oogenesis, BMP signaling in all species was maintained in similar patterns displaying only anterior-posterior polarity. However, BMP signaling during late oogenesis acquired patterns with distinct dorsal-ventral polarities in all species. Further analyses of late patterns revealed five unique patterning groups. Using genetic tools, we demonstrated that the BMP type I receptor thickveins (tkv) accounted for BMP signaling diversification. Based on signaling diversity, computational modeling was employed to predict patterns of tkv that were further tested experimentally. For most species, it was concluded that spatial changes to tkv guided diversification of late BMP signaling. In species belonging to the D. virilis-repleta radiation, tkv partially accounted for BMP signaling diversity and, for that radiation, the model proposes the involvement of another receptor in guiding BMP signaling. These results establish tkv as a major component in regulating BMP signaling diversification across 45 million years of evolution.
