Agricultural Systems Located in the Forest-Savanna Ecotone of the Venezuelan Amazonian. Are Organic Agroforestry Farms Sustainable?

The savannas located in the forest-savanna ecotone in the Venezuelan Amazon have unfertile sandy ultisols and entisols which show a very low crop production unless they are supplemented with large amounts of fertiliser. In spite of this restriction, local farmers have established long-term production systems by using low input doses of organic manure. The use of organic waste in unfertile ultisols and entisols typical of savannas have resulted in increases in organic matter content and biological activities in soils with respect to inorganic fertilised or non-fertilised natural savanna, which, in turn, may be related to increases in crop productivity. These results could be a successful and reliable soil management technique for rehabilitation of the South American savannas.
The Distance of the Large Magellanic Cloud Cluster NGC 1866

Hubble Space Telescope V, I photometry of stars in the Large Magellanic Cloud cluster NGC 1866 shows a well-defined cluster main sequence (MS) down to V = 25 mag, with little contamination from field or foreground stars. We use the MS fitting procedure to link the distance of NGC 1866 to the Hipparcos determination of the distance for the Hyades MS stars, making use of evolutionary prescriptions to allow for differences in the chemical composition. On this basis, we find a true distance modulus for NGC 1866 of 18.35 ± 0.05 mag. If the cluster is assumed to lie in the LMC plane, then the LMC modulus is 0.02 mag less.
Long Tail Tourism: New Geographies For Marketing Niche Tourism Products

ABSTRACT. The Long Tail concept refers to the Internet‐based economy that has enabled company success through a focus on highly specialized services and products that are not in high volume demand, but maybe in high‐value demand. The concept of the post‐tourist, for example, is a Long Tail phenomenon. Long Tail marketing approaches are proving success due to advances in communication technology and social networking that have given more people access to a broader range of goods and services and information. The Long Tail is not without its challenges, including increased global competition, and it has not abandoned geographic considerations. Geography, in fact, can help to differentiate niche products and must still be overcome to consummate the tourist experience. Portions of this article were originally published in: Lew, A. A. (2006).

Work output of planetary atmospheric engines: dissipation in clouds and rain

We compute the dissipation due to the drag of falling raindrops and cloud droplets, and find both to be significant sources of dissipation on Earth and possibly Titan. On other planets, they appear to be insignificant. We compare this dissipation with the latent heat transported by the drops and the thermodynamic efficiency with which it can be converted into work. This comparison suggests moist convection on Earth and Titan is similar, but on Jupiter latent heat alone does not provide enough work to lift the condensate against gravity.
Host Specificity and Temporal and Seasonal Shifts in Host Preference of a Web-Spider Parasitoid Zatypota percontatoria

Abstract Current knowledge about polysphinctine parasite wasps' interactions with their spider hosts is very fragmented and incomplete. This study presents the host specificity of Zatypota percontatoria (Müller) (Hymenoptera: Ichneumonidae) and its adaptation to varying host availability. Two years of field observations show that Z. percontatoria is a stenophagous parasitoid that parasitizes only five closely related web-building spiders of the family Theridiidae (Araneae). Within the Theridiidae it attacks only species belonging to a small group of species, here called the “Theridion” group. These hosts have a similar biology, but are available at different levels of abundance and at different sizes over the season. Laboratory experiments showed that this wasp species ignores linyphiid, araneid or dictynid spiders and accepts only theridiid spiders of the “Theridion” group. In the field study, wasp females preferred older juvenile and sub-adult female spider instars with intermediate body size. Only 5% of the parasitized spiders were males. Parasitism in the natural population of theridiid spiders was on average 1.3%. Parasitism was most frequent on two species, Theridion varians Hahn in 2007 and Neottiura bimaculata Linnaeus in 2008. The parasitization rate was positively correlated with spider abundance. The wasp responded adaptively to seasonal changes in host abundance and host body size and shifted host preference according to the availability of suitable hosts during, as well as between, seasons. In spring and summer the highest percentage of parasitism was on T. varians and in autumn it was on N. bimaculata.
Working Paper No. 155 Phone: 0171 631 6773 Ceo Pay, Shareholder Returns and Accounting Profitability

We assess the impact on CEO pay (including salary, cash bonus, and benefits in kind) of changes in both accounting and shareholder returns in 99 British companies in the years 1972-89. After correcting for heterogeneity biases inherent in the standard specifications of the problem, we find a strong positive relationship between CEO pay and within-company changes in shareholder returns, and no statistically significant relationship between CEO pay and within-company changes in accounting returns. Differences between firms in long term average profitability do appear to have a substantial effect on CEO pay, while differences between firms in shareholder returns add nothing to the within-firm pay dynamics. These findings call into question the rationale for explicitly share-based incentive schemes. Smith and two anonymous referees for their advice, and to Joyce Wheeler for assistance with data. The errors remain mine.
The Low-Power Nucleus of PKS 1246-410 in the Centaurus Cluster

We present Chandra, Very Large Array (VLA), and Very Long Baseline Array (VLBA) observations of the nucleus of NGC 4696, a giant elliptical in the Centaurus cluster of galaxies. Like M87 in the Virgo cluster, PKS 1246-410 in the Centaurus cluster is a nearby example of a radio galaxy in a dense cluster environment. In analyzing the new X-ray data we have found a compact X-ray feature coincident with the optical and radio core. While nuclear emission from the X-ray source is expected, its luminosity is low, < 10{sup 40} erg s{sup -1}. We estimate the Bondi accretion radius to be 30 pc and the accretion rate to be 0.01 M{sub {circle_dot}} y{sup -1} which under the canonical radiative efficiency of 10% would overproduce by 3.5 orders of magnitude the radiative luminosity. Much of this energy can be directed into the kinetic energy of the jet, which over time inflates the observed cavities seen in the thermal gas. The VLBA observations reveal a weak nucleus and a broad, one-sided jet extending over 25 parsecs in position angle -150 degrees. This jet is deflected on the kpc-scale to a more east-west orientation (position angle of -80 degrees).
Do congruent apologies facilitate forgiveness?

Research largely supports the apology–forgiveness cycle, a process in which perpetrators’ post-transgression apologies are reciprocated with victims’ forgiveness. This cycle is often facilitated by the mere provision of an apology. Yet, there are times in which apologies may be rejected. We hypothesised that when apologies matched victims’ apology preferences (i.e., congruent apologies), victims would be more likely to accept them and self-report higher levels of forgiveness. Using an autobiographical transgression-recall approach, participants (n = 102) provided self-report ratings on the apology they preferred receiving, the severity of the transgression, the type of apology they actually received from perpetrators, whether or not they accepted the apology offered to them, and forgiveness. Victims were more likely to accept apologies and report higher levels of forgiveness when perpetrators offered apologies that were congruent with victims’ preferred apologies, particularly apologies that met victims’ needs for empathy. The findings not only provide support for the apology–forgiveness cycle but also signify the importance of delivering apologies that meet the psychological needs of victims.
Improved Laplacian Smoothing of Noisy Surface Meshes

This paper presents a technique for smoothing polygonal surface meshes that avoids the well‐known problem of deformation and shrinkage caused by many smoothing methods, like e.g. the Laplacian algorithm. The basic idea is to push the vertices of the smoothed mesh back towards their previous locations. This technique can be also used in order to smooth unstructured point sets, by reconstructing a surface mesh to which the smoothing technique is applied. The key observation is that a surface mesh which is not necessarily topologically correct, but which can efficiently be reconstructed, is sufficient for that purpose.
Is a Decline of AMOC Causing the Warming Hole above the North Atlantic in Observed and Modeled Warming Patterns

AbstractThe pattern of global mean temperature (GMT) change is calculated by regressing local surface air temperature (SAT) to GMT for an ensemble of CMIP5 models and for observations over the last 132 years. Calculations are based on the historical period and climate change scenarios. As in the observations the warming pattern contains a warming hole over the subpolar North Atlantic. Using a bivariate regression of SAT to GMT and an index of the Atlantic meridional overturning circulation (AMOC), the warming pattern is decomposed in a radiatively forced part and an AMOC fingerprint. The North Atlantic warming hole is associated with a decline of the AMOC. The AMOC fingerprint resembles Atlantic multidecadal variability (AMV), but details of the pattern change when the AMOC decline increases, underscoring the nonlinearity in the response.The warming hole is situated south of deep convection sites, indicating that it involves an adjustment of the gyre circulation, although it should be noted that some mode.
Spectral Expansions of Overconvergent Modular Functions

The main result of this article is an instance of the conjecture made by Gouvea and Mazur in [11], which asserts that for certain values of r the space of r-overconvergent p-adic modular forms of tame level N and weight k should be spanned by the finite slope Hecke eigenforms. For N = 1, p = 2 and k = 0 we show that this follows from the combinatorial approach initiated by Emerton [9] and Smithline [16], using the classical LU decomposition and results of Buzzard–Calegari [1]; this implies the conjecture for all [Formula]. Similar results follow for p = 3 and p = 5 with the assumption of a plausible conjecture, which would also imply formulae for the slopes analogous to those of [1]. We also show that (for general p and N) the space of weight 0 overconvergent forms carries a natural inner product with respect to which the Hecke action is self-adjoint. When N = 1 and p ∈ {2, 3, 5, 7, 13}, combining this with the combinatorial methods allows easy computations of the q-expansions of small slope overconvergent eigenfunctions; as an application we calculate the q-expansions of the first 20 eigenfunctions for p = 5, extending the data given in [11].

Deficient Suppression of Default Mode Regions during Working Memory in Individuals with Early Psychosis and at Clinical High-Risk for Psychosis

Background: The default mode network (DMN) is a set of brain regions typically activated at rest and suppressed during extrinsic cognition. Schizophrenia has been associated with deficient DMN suppression, though the extent to which DMN dysfunction predates psychosis onset is unclear. This study examined DMN suppression during working memory (WM) performance in youth at clinical high-risk (CHR) for psychosis, early schizophrenia (ESZ) patients, and healthy controls (HC). We hypothesized that the DMN would show load-dependent suppression during WM retrieval in HC but not in ESZ, with CHR participants showing an intermediate pattern. Methods: fMRI data were collected from CHR (n = 32), ESZ (n = 22), and HC (n = 54) participants, ages 12–30. DMN regions were defined via seed-based connectivity analysis of resting-state fMRI data from an independent HC sample. Load-dependent deactivations of these DMN regions in response to WM probes were interrogated. Results: Healthy controls showed linear load-dependent increases in DMN deactivation. Significant Group-by-Load interactions were observed in DMN regions including medial prefrontal and lateral posterior parietal cortices. Group-by-Load effects in posterior DMN nodes resulted from less suppression at higher WM loads in ESZ relative to HC, with CHR differing from neither group. In medial prefrontal cortex, suppression of activity at higher WM loads was significantly diminished in both CHR and ESZ groups, relative to HC. In addition, investigation of dorsolateral prefrontal cortex (DLPFC) activations revealed that ESZ activated right DLPFC significantly more than HC, with CHR differing from neither group. Conclusion: While HC showed WM load-dependent modulation of DMN suppression, CHR individuals had deficient higher-load DMN suppression that was similar to, but less pronounced than, the distributed suppression deficits evident in ESZ patients. These results suggest that DMN dysregulation associated with schizophrenia predates psychosis onset.
Learning Translation Boundaries for Phrase-Based Decoding

Constrained decoding is of great importance not only for speed but also for translation quality. Previous efforts explore soft syntactic constraints which are based on constituent boundaries deduced from parse trees of the source language. We present a new framework to establish soft constraints based on a more natural alternative: translation boundary rather than constituent boundary. We propose simple classifiers to learn translation boundaries for any source sentences. The classifiers are trained directly on word-aligned corpus without using any additional resources. We report the accuracy of our translation boundary classifiers. We show that using constraints based on translation boundaries predicted by our classifiers achieves significant improvements over the baseline on large-scale Chinese-to-English translation experiments. The new constraints also significantly outperform constituent boundary based syntactic constrains.
On-Body Smartphone Localization with an Accelerometer

A user of a smartphone may feel convenient, happy, safe, etc., if his/her smartphone works smartly based on his/her context or the context of the device. In this article, we deal with the position of a smartphone on the body and carrying items like bags as the context of a device. The storing position of a smartphone impacts the performance of the notification to a user, as well as the measurement of embedded sensors, which plays an important role in a device’s functionality control, accurate activity recognition and reliable environmental sensing. In this article, nine storing positions, including four types of bags, are subject to recognition using an accelerometer on a smartphone. In total, 63 features are selected as a set of features among 182 systematically-defined features, which can characterize and discriminate the motion of a smartphone terminal during walking. As a result of leave-one-subject-out cross-validation, an accuracy of 0.801 for the nine-class classification is shown, while an accuracy of 0.859 is obtained against five classes, which merges the subclasses of trouser pockets and bags. We also show the basic performance evaluation to select the proper window size and classifier. Furthermore, the analysis of the contributive features is presented.
Sub-micron atmospheric aerosols in the surroundings of Marseille and Athens: physical characterization and new particle formation

The properties of atmospheric aerosol particles in Marseille and Athens were investigated. The studies were performed in Marseille, France, during July 2002 and in Athens, Greece, during June 2003. The aerosol size distri- bution and the formation and growth rates of newly formed particles were characterized using Differential Mobility Par- ticle Sizers. Hygroscopic properties were observed using a Hygroscopic Tandem Differential Mobility Analyzer setup. During both campaigns, the observations were performed at suburban, almost rural sites, and the sites can be consid- ered to show general regional background behavior depend- ing on the wind direction. At both sites there were clear pat- tern for both aerosol number concentration and hygroscopic properties. Nucleation mode number concentration increased during the morning hours indicating new particle formation, which was observed during more than 30% of the days. The observed formation rate was typically more than 1 cm 3 s 1 , and the growth rate was between 1.2-9.9 nm h 1 . Based on hygroscopicity measurements in Athens, the nucleation mode size increase was due to condensation of both water in- soluble and water soluble material. However, during a period of less anthropogenic influence, the growth was to a larger extent due to water insoluble components. When urban pol- lution was more pronounced, growth due to condensation of water soluble material dominated.
Site-specific terminal and internal labeling of RNA by poly(A) polymerase tailing and copper-catalyzed or copper-free strain-promoted click chemistry

The modification of RNA with fluorophores, affinity tags and reactive moieties is of enormous utility for studying RNA localization, structure and dynamics as well as diverse biological phenomena involving RNA as an interacting partner. Here we report a labeling approach in which the RNA of interest—of either synthetic or biological origin—is modified at its 3′-end by a poly(A) polymerase with an azido-derivatized nucleotide. The azide is later on conjugated via copper-catalyzed or strain-promoted azide–alkyne click reaction. Under optimized conditions, a single modified nucleotide of choice (A, C, G, U) containing an azide at the 2′-position can be incorporated site-specifically. We have identified ligases that tolerate the presence of a 2′-azido group at the ligation site. This azide is subsequently reacted with a fluorophore alkyne. With this stepwise approach, we are able to achieve site-specific, internal backbone-labeling of de novo synthesized RNA molecules.
Assessing Aspects of Acculturation in a Muslim American Sample: Development and Testing of the Acculturation Scale for Muslim Americans

Acculturation of Muslims into the American culture continues to be a topic of deep interest. The purpose of this study was to examine acculturation in a sample of both American-born and Immigrant Muslim Americans. Two hundred and fifty five Muslim Americans completed a scale designed to assess two aspects of acculturation within the population: adherence to Islamic identity and conformity to American social norms. The survey was distributed in both a paper-based and online anonymous format consisting of demographic questions and the acculturation scale designed for this study. Results revealed that both immigrants and U.S. born Muslim Americans demonstrate a strong adherence to their Islamic identity and low levels of conformity to American social norms. American-born Muslims scored significantly lower on conformity to American social norms than immigrant Muslims. Study findings are consistent with previous research suggesting that Muslim Americans are less likely to sacrifice religious values to assimilate. Specific item results provide insight into what aspects of American culture Muslims are more willing to adopt, and which they are likely to shun. These findings demonstrate the challenges Muslim Americans face integrating in an increasingly hostile host culture.
Heroism: A Conceptual Analysis and Differentiation between Heroic Action and Altruism

Heroism represents the ideal of citizens transforming civic virtue into the highest form of civic action, accepting either physical peril or social sacrifice. While implicit theories of heroism abound, surprisingly little theoretical or empirical work has been done to better understand the phenomenon. Toward this goal, we summarize our efforts to systematically develop a taxonomy of heroic subtypes as a starting point for theory building. Next we explore three apparent paradoxes that surround heroism—the dueling impulses to elevate and negate heroic actors; the contrast between the public ascription of heroic status versus the interior decision to act heroically; and apparent similarities between altruism, bystander intervention and heroism that mask important differences between these phenomena. We assert that these seeming contradictions point to an unrecognized relationship between insufficient justification and the ascription of heroic status, providing more explanatory power than risk-type alone. The results of an empirical study are briefly presented to provide preliminary support to these arguments. Finally, several areas for future research and theoretical activity are briefly considered. These include the possibility that extension neglect may play a central role in public's view of nonprototypical heroes; a critique of the positive psychology view that heroism is always a virtuous, prosocial activity; problems associated with retrospective study of heroes; the suggestion that injury or death (particularly in social sacrifice heroes) serves to resolve dissonance in favor of the heroic actor; and a consideration of how to foster heroic imagination.
How to design a digital individual learning RCT-study in the context of the Swedish preschool: experiences from a pilot-study

ABSTRACT This article takes its point of departure in the research methodology of a comprehensive and multi-disciplinary innovative intervention study in Swedish preschools with preschoolers aged 3–5, involving two digital learning games focusing early math and executive functions. Based on a combination of video-ethnography, focus groups, field notes and digital progression log data, the analysis of a pilot study of the pedagogical intervention challenges and extends theoretical and methodological perspectives on what it means to undertake an intervention study in this context. The aim is to discuss what a mixed-methods research approach may provide for the understanding of intervention methodology by illustrating how different types of data provide understandings of how and to what extent the intervention components are functional in the pedagogical setting. The conclusion the analysis supports is that unless children’s and preschool teachers’ meaning making of the unfolding actions in the digital interface make them engage in the activity and dynamically fits within the institutional preschool system, the intervention will not be functional. A pilot study can provide detailed understandings of why, how and in what contexts interventions as part of the dynamic preschool systems can be implemented with adherence and fidelity.
