description: Soil conditions of croplands are a frequent topic of scientific research. In contrast, less is known about large-scale commercial plantations of perennial crops such as oil palm. Oil palm is a globally important tropical commodity crop which contributes to both food and energy security due to its exceptional productivity. However, oil palm crops are associated with short lifecycles and high nutrient demands, which may disproportionately affect soil health. With the goal of exploring baseline soil properties in commercial oil palm plantations, we evaluated data from two large-scale soil surveys carried out in 2014/2015 and 2018/2019 across more than 400 fields located throughout Peninsular Malaysia. We examined variation in field-measured soil quality indicators with a focus on soil organic carbon content at three depths (0–15 cm, 15–30 cm, 30–45 cm) and investigated links with spatial covariates, including plantation age. We found SOC contents to be low (1.6–2%) across the sampled locations with limited correlation with spatial predictors employed in soil organic carbon modelling. Furthermore, we found that immature and young mature plantations, which consisted of fields that were re-planted as part of a 20-year-long oil palm rotation, were characterised by significantly lower soil organic carbon content than the mature plantations. This suggests that management practices should target younger oil palm plantations for soil organic conservation measures to increase the overall baseline SOC content, which will subsequently accumulate over the plantation’s lifespan. We further provide recommendations for future soil sampling efforts, which could increase the robustness of collected data and facilitate their use for soil monitoring through modelling approaches involving, for example, digital soil mapping.

description: We study the instanton calculus for N=4 super Yang-Mills theory in ten-dimensional Omega-background with the R-symmetry Wilson line gauge field. From the ADHM construction of instantons in the background, we obtain the deformed instanton effective action. For a certain case we get the effective action of N=2^* theory in the Omega-background. We also study the low-energy effective D(-1)-brane action for the D3/D(-1)-brane system in the R-R 3-form field strength backgrounds and find that the action agrees with the instanton effective action in the Omega-background.

Public interest standing and the environment : setting boundaries of participation in energy and natural resource decision making
Creators: name: Salomons, Geoffrey H.
Publisher: name: University of British Columbia
Year: 2012

description: Public participation processes are touted as an effective way to increase the capacity and legitimacy of policy making. Yet the focus in the public participation literature is primarily on issues of design, assuming a neutral, unbiased public that can be inserted into any public participation process. Consequently, attention is rarely given to who gets to participate in such processes. Recent changes to the Canadian environmental assessment process, an environmental decision making process with a strong public participation component, raise critical questions about who gets to participate. Specifically, the process narrowed the criteria of who can participate to those who are “directly affected”. The result is that a process designed to determine whether a particular project is in the public’s interest has restricted participation from any who were interested to those with the most direct material interests. The directly affected criteria, however, is not new. It is known in the context of administrative law as the test of standing. The test of standing asks who can legitimately bring forth a complaint before the court. As such, it is design to exclude more than include. Through a discussion of the theoretical relationship of representation this thesis presents arguments for why one might seek particular kinds of input for particular kinds of decisions. Analysis of several court cases where the standing test is applied is then used to illustrate both the restrictive nature of the test, as well as ambiguities regarding what constitutes being ‘affected’. This analysis suggests that the consequences of this criterion are that it undermines the ability of participants to effectively represent the public interest. The thesis concludes that restricting participation to the “directly affected” is far too narrow a test for processes like environmental assessment that are designed to determine the public interest.

Search for Dark Matter and Large Extra Dimensions in pp Collisions Yielding a Photon and Missing Transverse Energy
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Results are presented from a search for new physics in the final state containing a photon and missing transverse energy. The data correspond to an integrated luminosity of 5.0 inverse femtobarns collected in pp collisions at sqrt(s) = 7 TeV by the CMS experiment. The observed event yield agrees with standard-model expectations for the photon-plus-missing-transverse-energy events. Using models for production of dark-matter particles (chi), we set 90% confidence level (C.L.) upper limits of 13.6--15.4 femtobarns on chi production in the photon-plus-missing-transverse-energy state. These provide the most sensitive upper limits for spin-dependent chi-nucleon scattering for chi masses between 1 and 100 GeV. For spin-independent contributions, the present limits are extended to chi masses below 3.5 GeV. For models with 3--6 large extra dimensions, our data exclude extra-dimensional Planck scales between 1.65 and 1.71 TeV at 95% C.L.

description: This article presents a ten-item short scale for measuring digital competence. The scale is based on the Digital Competence Framework for Citizens, DigComp2.1 (Carretero et al., 2017). For our surveys, we used five items from the DigCompSat study (Clifford et al., 2020) and created five new ones to address the competence areas defined by DigCom2.1. We tested the scale on a sample of 1416 students from four countries (Germany, Lithuania, Austria, UK), using the questionnaire in two languages (English, German). The scale proved to be reliable (Cronbach’s α of 0.87 and McDonald’s ωt of 0.88) and valid (construct and content validity). Using the scale, we replicated findings from previous studies on differences in digital literacy by gender, study subject, and level of study. Despite the inhomogeneous structure of items from five different competence areas (according to DigComp2.1) and of two different types (specific, general), the scale does not seem to be multifactorial. A detailed analysis of digital competence and undergraduate research in the context of the pandemic shows: digital competence seems to support research competence and may even support inclusion.

description: We demonstrate estimating the total infrared luminosity, LIR, and star formation rates (SFRs) of star-forming galaxies at redshift 0 < z < 2.8 from single-band 24 micron observations, using local spectral energy distributions (SED) templates without introducing additional free parameters. Our method is based on characterizing the SEDs of galaxies as a function of their LIR surface density, which is motivated by the indications that the majority of IR luminous star-forming galaxies at 1 < z < 3 have extended star-forming regions, in contrast to the strongly nuclear concentrated, merger-induced starbursts in local luminous and ultraluminous IR galaxies. We validate our procedure for estimating LIR by comparing the resulting LIRs with those measured from far-IR observations at 0 < z < 2.8. AGNs were excluded using X-ray and 3.6-8.0 micron observations, which are generally available in deep cosmological survey fields. The Gaussian fits to the distribution of the discrepancies between the LIR measurements from single-band 24 micron and Herschel observations have sigma < 0.1 dex, with ~10% of objects disagreeing by more than 0.2 dex. Since the 24 micron estimates are based on SEDs for extended galaxies, this agreement suggests that ~90% of IR galaxies at high z are indeed much more physically extended than local counterparts of similar LIR, consistent with recent independent studies of the fractions of galaxies forming stars in the main-sequence and starburst modes, respectively. Because we have not introduced empirical corrections to enhance these estimates, in principle, our method should be applicable to lower luminosity galaxies. This will enable use of the 21 micron band of the Mid-Infrared Instrument (MIRI) on board the JWST to provide an extremely sensitive tracer of obscured SFR in individual star-forming galaxies across the peak of the cosmic star formation history.

description: The urgency to restore landscapes to counteract deforestation, soil degradation, and biodiversity loss has resulted in a global commitment to landscape restoration. Many frameworks and tools have emerged for the design and implementation of restoration activities. The frameworks tend to focus on selected dimensions of sustainability, with the majority focusing on the ecological. Current frameworks miss a balanced assessment of (planned) interventions taking into account also the social dimension relating to participation and ownership as well as improvement of livelihoods. The objective of this review is to assess current frameworks for identification of strength and weaknesses and to derive an integrated Forest Landscape Restoration (FLR) assessment framework model that shall help overcome current limitations. Applying systematic literature review, a total of 22 frameworks are selected and analyzed in-depth applying qualitative content analysis. Our review finds that frameworks vary with respect to their focus and restoration objectives. They also differ in relation to spatial and temporal scale, degree of stakeholder participation, consideration of ecological and social dimensions, monitoring and evaluation approaches, as well as provisions for exit strategies. Findings are summarized in form of an integrated FLR assessment framework, comprising six interlinked components: stakeholder participation, customization, time and scale of application, social-ecological balance, monitoring, evaluation and learning, and exit strategy. The proposed framework facilitates design and implementation of context specific interventions, balancing the nexus of social and ecological dimensions of FLR and acknowledges the need to also include reflection on learnings and planning of an exit strategy for long-term success.

description: The existence of optimal strategy in robust utility maximization is addressed when the utility function is finite on the entire real line. A delicate problem in this case is to find a "good definition" of admissible strategies, so that an optimizer is obtained. Under suitable assumptions, especially a time-consistency property of the set of probabilities which describes the model uncertainty, we show that an optimal strategy is obtained in the class of strategies whose wealths are supermartingales under all local martingale measures having a finite generalized entropy with at least one of candidate models (probabilities).

description: Halting and reversing the ongoing insect decline requires in-depth knowledge on key drivers. Due to their sensitivity to habitat quality, butterflies are valuable indicators for grassland management intensity, including mowing. However, most studies examining mowing regime impacts on butterflies are limited to small spatial extents. Here, we tested the potential of citizen science butterfly monitoring data for assessing landscape-level effects of mowing regimes (number of mowing events and timing of the first event) and edge density (density of boundaries between different land-cover types) on butterfly richness, abundance, and community composition. We used generalised linear mixed-effects models to relate nationwide data from the German Butterfly Monitoring Scheme (DEBMS) to high-resolution satellite imagery on mowing events in permanent grasslands (grasslands excluded from crop rotation). As butterfly transects may not consistently be located within grasslands, we ran our models for different thresholds from 0 to 50%, representing increasing shares of the transect route situated within permanent grasslands (10% intervals). We did not find significant associations between mowing regimes and butterflies when focussing on species richness and abundance of all species inhabiting open land. However, we found strong positive associations of delayed mowing with the abundance of grassland specialists with increasing grassland shares per transect. Further, we found negative associations of delayed mowing with the annual number of generations and of more frequent mowing with the abundance of specialists, depending on the share of grassland per transect. Edge density had a positive association with species richness and abundance of species inhabiting open land, as well as abundance of grassland indicator species and grassland specialists in landscapes with a low grassland share per transect. Our findings underscore the importance of low-intensity managed permanent grasslands at the landscape scale for specialised butterflies. Additionally, we highlight the importance of a high density of boundaries for open-land and specialised butterflies, particularly in landscapes with highly fragmented permanent grasslands. To improve future analyses of grassland management impacts, we recommend expanding DEBMS monitoring sites to cover a larger grassland management intensity gradient and to place more transects within grasslands.

A universal (model-independent) expression is obtained for the holomorphic symplectic two-form, which determines the second supersymmetry transformation. This two-form is associated with the two complex structures of the hyperkahler target space, which are complimentary to the one used to realize the target space as a Kahler manifold.

Making Sense of the Trump Administration's Fuel Economy Standard Rollback

description: On April 2, 2018, the US Environmental Protection Agency (EPA) announced that planned fuel economy increases for model year 2022–2025 cars and light trucks are too stringent and should be revised. The EPA thus initiated a process to set new standards for 2022–2025, in partnership with the National Highway Transportation Safety Administration (NHTSA).

Although the agencies may eventually ease fuel economy standards less than a full rollback of the standards to 2021 levels would imply, for illustrative purposes we assess the implications of a full rollback for gasoline consumption, oil imports, and carbon emissions. Given that the agencies’ 2016 analysis suggests that a full rollback would harm society on balance, we discuss which changes to the 2016 analysis might lead the agencies to conclude that a rollback benefits society.

To facilitate discussion of these important public policy issues, this paper makes two points about the EPA’s announcement:

Due to the gradual turnover of the on-road vehicle fleet, eliminating the tighter fuel economy standards for 2022–2025 would have small effects on gasoline consumption, greenhouse gas emissions, and oil imports during those years and even out to 2030. However, the ultimate impact of the weaker standards could be greater, especially if they hurt the progress of new technologies and the political momentum for tighter standards in the United States and in other countries over the longer term.

Changes in the social cost of carbon, fuel prices, miles traveled, and market shares of light trucks since the 2016 analysis are unlikely to cause the benefits of rolling back the standards to exceed the costs. If the agencies conclude that the benefits of rolling back the standards exceed the costs, the reasoning will likely be based on other factors, such as consumer willingness to pay for fuel-saving technologies or the cost and effectiveness of those technologies.

description: Business process redesign has received considerable attention in research and practice. An important task contributing to redesign is idea generation. It has been argued that the choice of technique influences redesign outcomes, but empirical evidence is largely missing. In this paper, we examine the role of idea generation in business process redesign by comparing two different kinds of techniques: exploitative and explorative redesign techniques. Often, exploitative techniques are expected to yield more appropriate solutions, while explorative techniques are associated with more creative outcomes. To investigate such propositions, we consider the Best Practices of Process Redesign as an example of an exploitative redesign technique and the Business Process Design Space as an explorative redesign technique. We conducted a free-simulation experiment to study the empirical impact of the choice of redesign techniques on outcomes. We find that the Business Process Design Space leads to a higher number of redesign ideas, which are also more diverse. These are more creative and novel than ideas produced by the Best Practices of Process Redesign. Against expectation, the best practices as an exploitative approach do not produce more appropriate nor impactful ideas in our task design. Since both approaches cover different areas of improvement, a key implication of our work is that they should not be seen as isolated approaches to redesign; rather, they should be purposefully combined to not only create novel but also operational business process redesigns.

description: We consider an optimal liquidation problem with instantaneous price impact and stochastic resilience for small instantaneous impact factors. Within our modelling framework, the optimal portfolio process converges to the solution of an optimal liquidation problem with general semimartingale controls when the instantaneous impact factor converges to zero. Our results provide a unified framework within which to embed the two most commonly used modelling frameworks in the liquidation literature and provide a foundation for the use of semimartingale liquidation strategies and the use of portfolio processes of unbounded variation. Our convergence results are based on novel convergence results for BSDEs with singular terminal conditions and novel representation results of BSDEs in terms of uniformly continuous functions of forward processes.

description: It was recently shown that our peculiar velocity βwith respect to the CMB induces mixing among multipoles and off-diagonal correlations at all scales which can be used as a measurement of β, which is independent of the standard measurement using the CMB temperature dipole. The proposed techniques rely however on a perturbative expansion which breaks down for \ell \gtrsim 1/(β) \approx 800. Here we propose a technique which consists of deboosting the CMB temperature in the time-ordered data and show that it extends the validity of the perturbation analysis multipoles up to \ell \sim 10000. We also obtain accurate fitting functions for the mixing between multipoles valid in a full non-linear treatment. Finally we forecast the achievable precision with which these correlations can be measured in a number of current and future CMB missions. We show that Planck could measure the velocity with a precision of around 60 km/s, ACTPol in 4 years around 40 km/s, while proposed future experiments could further shrink this error bar by over a factor of around 2.

description: We solve the superhedging problem for European options in an illiquid extension of the Black–Scholes model, in which transactions have transient price impact and the costs and strategies for hedging are affected by physical or cash settlement requirements at maturity. Our analysis is based on a convenient choice of reduced effective coordinates of magnitudes at liquidation for geometric dynamic programming. The price impact is transient over time and multiplicative, ensuring nonnegativity of underlying asset prices while maintaining an arbitrage-free model. The basic (log-)linear example is a Black–Scholes model with a relative price impact proportional to the volume of shares traded, where the transience for impact on log-prices is modelled like in Obizhaeva and Wang (J. Financ. Mark. 16:1–32, 2013 ) for nominal prices. More generally, we allow nonlinear price impact and resilience functions. The viscosity solutions describing the minimal superhedging price are governed by the transient character of the price impact and by the physical or cash settlement specifications. The pricing equations under illiquidity extend no-arbitrage pricing à la Black–Scholes for complete markets in a non-paradoxical way (cf. Çetin et al. (Finance Stoch. 14:317–341, 2010 )) even without additional frictions, and can recover it in base cases.

description: This article re-evaluates the 22 so-calledTabulae Iliacae. Where most scholars (especially in the English-speaking world) have tended to dismiss these objects as ‘trivial' and ‘confused’, or as ‘rubbish’ intended for the Roman ‘nouveaux riches’, this article relates them to the literary poetics of the Hellenistic world, especially Greek ecphrastic epigram. Concentrating on the tablets' verbal inscriptions, the article draws attention to three epigraphic features in particular. First, it explores the various literary allusivenesses of the two epigrammatic invocations inscribed on tablets 1A and 2NY; second, it examines the Alexandrian diagrammatic word-games on the reverse of sevenTabulae(2NY, 3C, 4N, 5O, 7Ti, 15Ber, 20Par), relating these to the pictorial-poetic games of the Greektechnopaegnia; third, it discusses the possible hermeneutic significance of associating six tablets with ‘Theodoreantechne’ (1A, 2NY, 3C, 4N, 5O, 20Par), comparing a newly discovered epigram by Posidippus (67 A-B). All of these allusions point to a much more erudite purpose and clientele: the tablets toyed with Hellenistic visual-verbal relations at large.

description: No abstracts are to be cited without prior reference to the author.With the exception of selectivity trials for target species and investigations into protected species bycatch, the other ecological effects of static net fisheries, such as impacts on non-target and non-commercial species, have not been widely studied. • The growing scientific and public interest in conservation and biodiversity issues means that assessing the wider effects of all gear types is becoming increasingly important. • Furthermore, the imminent introduction of potentially widespread MPAs in UK waters may lead to changes in patterns of fishing effort through displacement or diversification, which could significantly alter the environmental footprint of the catching sector. • Data describing the total catch characteristics of different net types will improve our understanding of the potential impacts of these gears and should therefore allow detailed assessments to be made of the efficacy of existing and planned spatial management measures. • The aim of this study is to investigate whether differences exist in the catch characteristics, including species compositions, catch rates and size distributions from different static net types. • Our analyses are based on catch data from 2 different sources: 1. Commercial vessel catch data from approximately 3000 static net hauls monitored in ICES subarea VII since 2005, during the course of the UKs bycatch monitoring programme and 2. Experimental trials consisting of 50 semi-controlled hauls designed to estimate the relative effects of 4 commonly used static net types in inshore fisheries in SW Britain.

Climate governance and the welfare state : a cross-national comparison
Creators: name: Groenewegen, Tracy
Publisher: name: University of British Columbia
Year: 2012

description: This thesis explores the theoretical and empirical connection between the welfare state and national-level climate governance, drawing together the concepts of the ecological state, ecological modernization, and varieties of capitalism. It is argued that the eco-state represents the latest evolutionary phase of the modern state, though no state has achieved full eco-state status. In its nascence it has thus been layered on top of institutional structures that characterize earlier phases, namely welfare and production regimes. As a result, 'eco-state regimes' – differential degrees of eco-state development – have begun to take shape, mapping onto these two foundational regimes such that coordinated market economies with social democratic welfare states are the vanguards of ecological modernization, a discourse that dominates environmental policy arenas across the advanced capitalist world but that these particular countries have embraced with especial gusto and have the institutional and governance capacities to make a reality. It is proposed, then, that this ‘family of nations’ would exhibit comparatively strong climate governance from an ecological modernization perspective. Using available data, I assess the empirical relevance of this theoretical framework and suggest how it might be strengthened. A basic quantitative analysis of scores on the Climate Change Performance Index provides some support for the theory but the existence of two substantially discrepant cases – the United Kingdom and Finland – indicates that it is overly simplistic. I explore these two cases further in considerable depth using an interdisciplinary, comparative case study approach, which brings to light a range of influential extra-theoretical factors, including climatic, geographic, demographic, economic, political, historical, and geopolitical factors. My findings therefore highlight the importance of a broader conception of national context to a fuller understanding of variation in national-level climate governance and suggest an additional, alternative evolutionary path for countries with liberal market economies and liberal welfare states. However, the findings also call into question the possibility of a fully developed eco-state, and the likelihood of ecological modernization as a definitive solution to global climate change, in the context of globalized capitalism.

description: Arbuscular mycorrhizal fungi (AMF) typically provide a wide range of nutritional benefits to their host plants, and their role in plant water uptake, although still controversial, is often cited as one of the hallmarks of this symbiosis. Less attention has been dedicated to other effects relating to water dynamics that the presence of AMF in soils may have. Evidence that AMF can affect soil hydraulic properties is only beginning to emerge. In one of our recent experiments with dwarf tomato plants, we serendipitously found that the arbuscular mycorrhizal fungus ( Rhizophagus irregularis ‘PH5’) can slightly but significantly reduce water holding capacity (WHC) of the substrate (a sand–zeolite–soil mixture). This was further investigated in a subsequent experiment, but there we found exactly the opposite effect as mycorrhizal substrate retained more water than did the non-mycorrhizal substrate. Because the same substrate was used and other conditions were mostly comparable in the two experiments, we explain the contrasting results by different substrate compaction, most likely caused by different pot shapes. It seems that in compacted substrates, AMF may have no effect upon or even decrease the substrates’ WHC. On the other hand, the AMF hyphae interweaving the pores of less compacted substrates may increase the capillary movement of water throughout such substrates and cause slightly more water to remain in the pores after the free water has drained. We believe that this phenomenon is worthy of mycorrhizologists’ attention and merits further investigation as to the role of AMF in soil hydraulic properties.

description: In mobile animals, selection pressures resulting from spatio-temporally varying ecological factors often drive adaptations in migration behavior and associated physiological phenotypes. These adaptations may manifest in ecologically and genetically distinct ecotypes within populations. We studied a meta-population of northern pike ( Esox lucius ) in brackish environments and examined intrapopulation divergence along environmental gradients. Behavioral phenotypes in habitat use were characterized via otolith microchemistry in 120 individuals sampled from brackish lagoons and adjacent freshwater tributaries. We genotyped 1514 individual pike at 33 highly informative genetic markers. The relationship between behavioral phenotype and genotype was examined in a subset of 101 pikes for which both phenotypic and genomic data were available. Thermosaline differences between juvenile and adult life stages indicated ontogenetic shifts from warm, low-saline early habitats towards colder, higher-saline adult habitats. Four behavioral phenotypes were found: Freshwater residents, anadromous, brackish residents, and cross-habitat individuals, the latter showing intermediary habitat use between brackish and freshwater areas. Underlying the behavioral phenotypes were four genotypes, putative freshwater, putative anadromous, and two putatively brackish genotypes. Through phenotype-genotype matching, three ecotypes were identified: (i) a brackish resident ecotype, (ii) a freshwater ecotype expressing freshwater residency or anadromy, and (iii) a previously undescribed intermediary cross-habitat ecotype adapted to intermediate salinities, showing limited reliance on freshwater. Life-time growth of all ecotypes was similar, suggesting comparable fitness. By combining genetic data with lifelong habitat use and growth as a fitness surrogate, our study revealed strong differentiation in response to abiotic environmental gradients, primarily salinity, indicating ecotype diversity in coastal northern pike is higher than previously believed.
