description: The Food and Agriculture Organization estimates that close to 9% of the world’s soils are affected by salinity. The purpose of this article is to discuss qualitative social science findings on alternative ways of conceptualizing salinization in Kazakhstan and how these findings could be leveraged for transformative knowledge towards sustainability. We highlight dimensions of land degradation that are doubly obscured: the under-represented issue of salinization, and vernacular knowledge on salinization. The article draws on qualitative data collection methods, including eighteen months of participant observation, workshop transcripts and archival records. Three research findings are presented. First, there is an analysis of the framing of environmental issues common among policymakers in the region. Second, these frameworks are contrasted with novel data on how local farming communities understand and deal with salinization. These two research results enable extrapolating a third finding: how such locally based knowledge could be harnessed towards solving salinization issues. Beyond the specific issue of salinization, the results of this research suggest potentially valuable design principles relating to specific ways that the environmental knowledge of expert farmers and scientific experts could be paired. In the case of Central Asia, models based on the local culture can be adapted, such as hosting and apprenticeship relationships. This example suggests transferable lessons on how to forge social learning towards sustainability that start from imperfect local tools (bottom-up) rather than from internationally promoted but socially distant blueprints (top-down).

description: As the deepening climate crisis shows, our greatest scientific challenge is to turn abstract understanding into doing. This means that the classic divide in research between ‘basic’, ‘applied’ and ‘outreach’ phases no longer adequately serve the need for transformative social learning. What can this kind of transformation look like in a world region such as Central Asia, with its own distinct legacies of environmental and social flourishing and suffering? What are the consequences of Central Asia’s particular forms of structural opportunity and violence around knowledge-creation? This paper discusses transdisciplinary research models in light of real collaborations on the banks of the Naryn and Syr Darya rivers. I examine the strengths and weaknesses of research with a wide range of actors in Central Asia such as irrigation specialists, artists and social scientist. Drawing on this experience, the paper analyses how broad regional trends in activism and scholarship intersect with global developments in knowledge-production methods and economies.
Glitches Induced by the Core Superfluid

Subjects: subject: Astrophysics (astro-ph)

description: The long-term evolution of the relative rotation of the core superfluid in a neutron star with respect to the rest of the star, at different radial distances from the rotation axis, is determined through model calculations. The core superfluid rotates at a different rate (faster, in young pulsars), while spinning down at the same steady-state rate as the rest of the star, because of the assumed pinning between the superfluid vortices and the superconductor fluxoids. We find that the magnitude of this rotational lag changes with time and also depends on the distance from the rotation axis; the core superfluid supports an evolving pattern of differential rotation. We argue that the predicted change of the lag might occur as discrete events which could result in a sudden rise of the spin frequency of the crust of a neutron star, as is observed at glitches in radio pulsars. This new possibility for the triggering cause of glitches in radio pulsars is further supported by an estimate of the total predicted excess angular momentum reservoir of the core superfluid. The model seems to offer also resolutions for some other aspects of the observational data on glitches.

description: Expectations are that the agricultural sector will have to expand the use of water for irrigation to meet rising food demand, given population and income growth. At the same time, the competition for water resources is growing in many regions. Increasing water productivity in agriculture is widely seen as a critical response to help address these challenges. Yet much of the public debate is vague on the meaning of agricultural water productivity—often emphasizing “more crop per drop” as if water were the only input that mattered—, and approaches for assessing and increasing water productivity are seldom addressed systematically. This paper discusses conceptual issues that should be kept in mind when assessing agricultural water productivity, and presents findings from what may be the first survey of the agricultural productivity and efficiency literature with regard to the explicit inclusion of water aspects in productivity and efficiency measurements. The survey includes studies applying single-factor productivity measures, total factor productivity indices, frontier models, and deductive models. A key finding is that most studies either incorporate field- and basin-level aspects but focus only on a single input (water), or they apply a multi-factor approach but do not tackle the basin-level aspects. It seems that no study on agricultural water productivity has yet presented an approach that accounts for multiple inputs and basin-level issues. However, deductive methods provide the flexibility to overcome some of the limitations of the other methods.

description: Die vorliegende Bachelorarbeit beschäftigt sich mit der Verbreitung von Fake News auf der Social-Media-Plattform TikTok. Die Herausforderung, irreführende Informationen aus der Vielzahl an Beiträgen zu identifizieren, nimmt kontinuierlich zu. Es wird der Forschungsfrage nachgegangen, wie Fake News auf der Plattform erkannt werden können und welche präventiven Maßnahmen zur Bekämpfung von Fehlinformationen entwickelt werden sollten. Die Forschungsfrage wird anhand aktueller Forschungsliteratur beantwortet. Um umfangreich auf das Thema eingehen zu können, wird zusätzlich erläutert, wie Fake News entstehen, welchen Nutzen sie haben und warum sie sich durch den TikTok-Algorithmus so rasant verbreiten. Zu den wichtigsten Ergebnissen gehört die Notwendigkeit einer umfangreichen Analyse der TikTok-Accounts, der Absichten hinter den Beiträgen sowie der Inhalte selbst. Darüber hinaus sollten Quellen und deren Autoren sorgfältig geprüft werden. Eine weitere präventive Maßnahme ist die frühzeitige Vermittlung von Medienkompetenz an Schulen, die mithilfe von Workshops umgesetzt werden kann. Darüber hinaus ist eine verstärkte Durchsetzung von Strafen notwendig, um die Verbreitung von Falschinformationen auf TikTok einzudämmen. Zukünftig müssen sowohl die Richtlinien von TikTok als auch staatliche Maßnahmen konsequenter durchgesetzt werden.

description: A significant amount of the forestland in Montana is in need of mechanical forest restoration treatments, which can improve forest health and reduce wildfire risk, but can be expensive to implement and produce little merchantable timber. One option for disposal of the small diameter material produced by these treatments is to utilize it to produce energy, which can offset some fossil fuel use and facilitate the treatment of more acres of forest. However the harvest and utilization of woody biomass for energy generation can have negative effects on air quality and forest health as well. This study used a choice modeling nonmarket valuation survey to quantify the preferences of residents of Montana toward the potential effects of harvesting woody biomass from public forests during restoration treatments and utilizing the biomass to generate energy.

description: We address experimentally the problem of how the structure of a surface monolayer determines the visco-elasticity of the interface. Optical microscopy and surface quasi--elastic light scattering have been used to characterize aggregation of CaCO$_3$ particles at the air--water interface. The structures formed by cluster-cluster aggregation are two dimensional fractals which grow to eventually form a percolating network. This process is measured through image analysis. On the same system we measure the dynamics of interfacial thermal fluctuations (surface ripplons), and we discuss how the relaxation process is affected by the growing clusters. We show that the structures start damping the ripplons strongly when the two length scales are comparable. No macroscopic surface pressure is measured and this is in contrast to lipid, surfactant or polymer monolayers at concentrations corresponding to surface coverage. This observation and the difficulty in fitting the ripplon spectrum with traditional models suggest that a different physical mechanism might be responsible for the observed damping of ripplons in this system.

We first prove the existence of a compact attractor in the region with biological meaning. Under the assumption that the dimerization reactions are fast, in this attractor we reduce the three-dimensional system to a simpler two-dimensional system on the persistent normally hyperbolic slow manifold.

description: In this second paper of the catalogue series of galaxies behind the southern Milky Way, we report on the deep optical galaxy search in the Crux region (289deg <= l <= 318deg and -10deg <= b <= 10deg) and the Great Attractor region (316deg <= l <= 338deg and -10deg <= b <= 10deg). The galaxy catalogues are presented, a brief description of the galaxy search given, as well as a discussion on the distribution and characteristics of the uncovered galaxies. A total of 8182 galaxies with major diameters D >= 0.2 arcmin were identified in this ~850 square degree area: 3759 galaxies in the Crux region and 4423 galaxies in the Great Attractor region. Of the 8182 galaxies, 229 (2.8%) were catalogued before in the optical (3 in radio) and 251 galaxies have a reliable (159), or likely (92) cross-identification in the IRAS Point Source Catalogue (3.1%). A number of prominent overdensities and filaments of galaxies are identified. They are not correlated with the Galactic foreground extinction and hence indicative of extragalactic large-scale structures. Redshifts obtained at the South African Astronomical Observatory (SAAO) for 518 of the newly catalogued galaxies in the Crux and Great Attractor regions (Fairall et al. 1998; Woudt et al. 1999) confirm distinct voids and clusters in the area here surveyed. With this optical galaxy search, we have reduced the width of the optical `Zone of Avoidance' for galaxies with extinction-corrected diameters larger than 1.3 arcmin from extinction levels A_B >= 1.0 mag to A_B >= 3.0 mag: the remaining optical Zone of Avoidance is now limited by |b| <= 3deg (see Fig. 16).

description: What symmetry breaking would be required for gauginos from a supersymmetric theory to behave like left-handed quarks of the Standard Model? Starting with a supersymmetric SU(3)xSU(3)xU(1)xU(1) gauge theory, the 18 adjoint-representation gauginos are replaced with 2 families of 9 gauginos in the (3,3*) representation of the group. After this explicit breaking of supersymmetry, two-loop quadratic divergences still cancel at a unification scale. Coupling constant unification is supported by deriving the theory from an SU(3)xSU(3)xSU(3)xSU(3) Grand Unified Theory (GUT). Sin^2 of the Weinberg angle for the GUT is 1/4 rather than 3/8, leading to a lower unification scale than usually contemplated, ~10^9 GeV. After spontaneous gauge symmetry breaking to SU(3)xSU(2)xU(1), the theory reproduces the main features of the Standard Model for two families of quarks and leptons, with gauginos playing the role of left-handed quarks and sleptons playing the role of the Higgs boson. An extension to the theory is sketched that incorporates the third family of quarks and leptons.

description: We investigate the responsiveness of the 2798AA Mg II broad emission line in AGN on timescales of several years. Our study is based on a sample of extremely variable AGN as well as a broad population sample. The observed response of the line in previous studies has been mixed. By focussing on extreme variability ($|Δg|>$ 1) we find that Mg II clearly does respond to the continuum. However, the degree of responsiveness varies strikingly from one object to another; we see cases of Mg II changing by as much as the continuum, more than the continuum, or very little at all. In 74% of the highly variable sample the behaviour of Mg II corresponds with that of H$β$, with 30% of the objects showing large variations in both lines. We do not detect any change in the line width that would correspond to Broad Line Region `breathing', in accordance with results from literature. Some of the objects in our highly variable sample show a clear asymmetry in the Mg II profile. This skewness can be both to the blue and the red of the line centre. Results from our broad population sample show that highly variable quasars have lower Eddington ratios. This result holds for the variability of the continuum, but the correlation is significantly reduced for the variability of the Mg II line. For the first time, we present an overview of the value of the intrinsic Baldwin Effect for Mg II in a large sample.

description: The corn farmer has benefited from high corn price. However, the corn price plunged from its high price in 2012 to as low as $ 4.46 per bushel in 2013. The drop in corn price and intense competition from the global grain markets make farms that are non-efficient struggle economically. Pure technical, overall technical, and scale efficiency were measured to analyze the competitiveness of a sample of Kansas corn farmers. The average of pure technical, overall technical, and scale efficiency for irrigated farm, non-irrigated conventional farm and non-irrigated non-tillage farm are below 70%. Farmers increased their efficiency during drought in 2012 and lower corn price. Government payments and insurance expenditure were found to be negatively correlated with efficiency. Farmers should focus on utilizing land and labor more efficiently rather than expanding their size.

description: Genus Alliphis Halbert, 1923
 Copriphis (Alliphis) Halbert, 1923: 369. Type species Gamasus halleri G. & R. Canestrini 1881: 1077, by monotypy.
 Diagnosis of genus. Eviphididae with a normally-developed sternal shield bearing three pairs of setae; coxal setae unmodified, setiform; anal shield with one pair of para-anal setae and an unpaired post-anal seta; opisthsogastric skin otherwise unsclerotised; trochanter I with six setae; genu III with two ventral setae; peritrematal shields well developed, extending forward at least as far as mid-level of coxa I, not greatly expanded behind coxae IV; epistome with a long serrated medial process; palp tarsus without macroeupathidia.
 Notes on the genus. Identification of species of Alliphis is difficult. The best available key is that of Mašán (1994), but it only includes 10 of the 28 species currently placed in the genus. The recent study of the genus by Mašán & Halliday (2010) includes only the European fauna. A complete review of the genus will need to include, for example, the species described in recent years from Armenia (Arutunian 1991, 1992), India (Ramaraju & Mohanasundaram 1996) and China (e. g. Gu & Fan 1997a; Ma & Wang 1998; Li 2001). Mašán & Halliday (2009) described three new genera of Eviphididae, two of which were based on species that were previously included in Alliphis. According to the key of Mašán (1994), and descriptions of other species, the females of all species of Alliphis that are adequately known have the first pair of sternal lyrifissures oriented either obliquely or parallel to the long axis of the body. The description and illustrations of A. oviforme (Schweizer) and A. serratochaetae Ramaraju & Mohanasundaram are not adequate to allow this decision to be made, and the females of a few species are unknown. The Australian fauna includes the first species in which the first pair of sternal lyrifissures are unequivocally transverse in the adult female, and this species also has several unusual character states for the genus.

The goal is to hunt for structures, not so much for exact formulas, which are necessarily complicated, before the right language is found to represent them. Some entities, reminiscent of representation theory, clearly emerge, but a lot of work remains to be done to identify the relevant ones. As a practical application, we obtain a cubic (first non-perturbative) contribution to the prepotential for any n.

description: For a hypersurface in ${\mathbb R}^3$, Willmore flow is defined as the $L^2$--gradient flow of the classical Willmore energy: the integral of the squared mean curvature. This geometric evolution law is of interest in differential geometry, image reconstruction and mathematical biology. In this paper, we propose novel numerical approximations for the Willmore flow of axisymmetric hypersurfaces. For the semidiscrete continuous-in-time variants we prove a stability result. We consider both closed surfaces, and surfaces with a boundary. In the latter case, we carefully derive weak formulations of suitable boundary conditions. Furthermore, we consider many generalizations of the classical Willmore energy, particularly those that play a role in the study of biomembranes. In the generalized models we include spontaneous curvature and area difference elasticity (ADE) effects, Gaussian curvature and line energy contributions. Several numerical experiments demonstrate the efficiency and robustness of our developed numerical methods.

description: We study the role of food price rising and income generating assets as determinants of household food insecurity among the extreme poor in rural Bangladesh for the period 2002-2011. We do so in the context of an anti-poverty program, targeting the ultra-poor (TUP), which transferred productive livestock assets to the very poor. We find a positive significant impact of the asset transfers on household’s food security irrespective of whether we use subjective or objective measures of food security. Most importantly we find that the long-term impact of the program (estimated over 2002-2011) is smaller compared to mid-term (2002-2008) and short-term (2002-2005) impacts for all the indicators. We test whether this declining program impact is driven by the steep rise in food prices in the post-2007 period. We find that in the pre-crisis period participant households benefited while in the post crisis period they affected negatively by the price shock. This result explains the declining effect of TUP program. Our analysis therefore illustrates how the external shocks can undermine the effectiveness of an otherwise well-functioning anti-poverty program.

description: Das Ziel dieser Arbeit ist es, die Bildungspotentiale, die eine Maker Education aufweist, zu analysieren. Dazu wird folgende Forschungsfrage gestellt: „Wo liegen mögliche Potentiale einer Maker Education in Bezug auf die medienpädagogische Praxisarbeit aus Perspektive der strukturalen Medienbildung?“ Das Modell der strukturalen Medienbildung von Benjamin Jörissen und Winfried Marotzki, das sich an einem prozessualen Bildungsbegriff orientiert und Komplexitäts- sowie Mediatisierungsschübe moderner Gesellschaften als ursächlich für steigende Kontingenzerfahrungen ansieht, wird als anschlussfähig an ein Paradigma der Postdigitalität betrachtet. Zunächst werden verschiedene Konzepte (von Mediatisierung, Medienkompetenz über Medienbildung bis zu strukturaler Medienbildung) eingeführt und Einblicke in die Maker Bewegung sowie medienpädagogisches Making gegeben. Durch die Methode der Textanalyse werden weiterhin die Handlungsprinzipien selbstbestimmt, prosumisch, prozessorientiert, (physisch)erschaffend und glokal sowie die Handlungsmodi ludisch, iterativ, kreativ, tentativ, alteritär, selbstbestimmt, (selbs-)reflexiv, kollaborativ und explorativ der Maker Education entwickelt und den Dimensionen der strukturalen Medienbildung zugeordnet. Dadurch wird aufgezeigt, in welchem Maß medienpädagogisches Making neuartige Bildungsprozesse in Gang setzten kann. Die Analyse legt nahe, dass die Bildungspotentiale der Maker Education erheblich sind. Aufgrund des formalen Umfangs dieser Arbeit handelt um erste theoretische Erörterungen. Es wird daher abschließend darauf hingewiesen, dass es weiterführenden Forschungsbedarf gibt.

description: Recently FDA proposed a new Nutrition Facts panel. In this study, we analyze whether the proposed changes to the Nutrition Facts panel have the potential to increase consumers’ attention. In doing so, we account for involvement and familiarity as determinants of attention. In order to measure attention we conducted a laboratory experiment using eye tracking with two treatments testing differences in consumer attention towards the current and the proposed Nutrition Facts panel. Our findings highlight empirical evidence regarding the separate and joint effect of involvement with the Nutrition Facts panel and product familiarity on consumers’ visual attention. Our results suggest that the proposed new format of the Nutrition Facts panel has a significant positive effect on consumers’ attention. The proposed label leads low-involvement or less-familiar consumers to attend longer to the Nutrition Facts panel. Our findings are important for policy makers and the food industry more generally in providing critical information regarding the outcomes of a revision of the Nutrition Facts panel.

description: We investigated the nanometer scale height fluctuations of 3T3 fibroblast cells with the atomic force microscope (AFM) under physiological conditions. Correlation between these fluctuations and lateral cellular motility can be observed. Fluctuations measured on leading edges appear to be predominantly related to actin polymerization-depolymerization processes. We found fast (5 Hz) pulsatory behavior with 1--2 nm amplitude on a cell with low motility showing emphasized structure of stress fibres. Myosin driven contractions of stress fibres are thought to induce this pulsation.

description: According to the crystal structure of MgB$_{2}$ and band structure calculations quasi-two-dimensional (2D) boron planes are responsible for the superconductivity. We report on critical fields and resistance measurements of 30 nm thick MgB$_{2}$ films grown on MgO single crystalline substrate. A linear temperature dependence of the parallel and perpendicular upper critical fields indicate a 3D-like penetration of magnetic field into the sample. Resistivity measurements, in contrast, yield a temperature dependence of fluctuation conductivity above T$_{c}$ which agrees with the Aslamazov-Larkin theory of fluctuations in 2D superconductors. We consider this finding as an experimental evidence of two-dimensional nucleation of superconductivity in MgB$_{2}$.

description: Despite considerable literature regarding other modes of transportation, little is written about oil pipelines. This is remarkable given that oil pipelines move 17% of all intercity ton miles, but also understandable because they have a low public profi le and, with near total automation, have few employees. This article attempts to bridge the gap by comparing pipeline operations and those of the other modes, showing striking similarities along with a few signifi cant differences. It also portrays pipeline markets and their changing trends. In recent years, oil pipelines have served an industry that is experiencing rapidly shifting geographical markets, proliferation of new products, and outsourcing of transportation by shippers. The pipeline industry has responded to these challenges with increased competitive entry, numerous capital construction projects, and a high reliance on technology. These issues, along with the regulatory constraints and responses are portrayed.

description: A new method to compute the symplectic structure of a quantum field theory with non trivial boundary conditions is proposed. Following the suggestion in \cite{ho:gnus, ardalan}, we regard that the boundary conditions are second class constraints in the sense of the Dirac's method. However, we show that this proposal is more useful if we consider an inverse of the Holographic map between a theory defined in the boundary to another with constraints but without boundary.

description: This paper reviews the Transportation Security Administration’s forthcoming computerized profi ling system called “Secure Flight.” Secure Flight is the latest generation of so-called “computer assisted passenger pre-screening systems.” Such systems invite considerable privacy and civil liberty concerns, evoking references to an Orwellian society. This article confronts the central legal, political, and social tension borne of profi ling systems such as Secure Flight, namely the conflict between the ideal of a “right to be let alone” (Warren and Brandeis 1890) relative to the post-Sept. 11 ultimatum of former American Airlines Chairman and CEO Robert L. Crandall (2002): “You want to travel on the airline system? You give up your privacy. You don’t want to give up your privacy? Don’t fly. Your privacy isn’t equal to the safety of the rest of us.”
