RusNeuroPsych: Open Corpus for Study Relations between Author Demographic, Personality Traits, Lateral Preferences and Affect in Text

A text reflects a range of combinations of individual inter-acting characteristics of its author, both stable (gender, psychological traits, neuropsychological characteristics) and variable (feelings, emotions). It is obvious that it is not in isolation but in a combination that a variety of characteristics comes forth in a text. For example, according to some studies, men and women express their emotions in a text in different ways. It is obvious, though that there are other characteristics that influence the way one chooses to express his/her emotions. Studies of these ways are critical multidisciplinary problems that call for text corpora providing relevant metadata. The paper is devoted to the description of a manually collected corpus of texts (letters to a friend and narratives about pictures from Thematic apperception test, i.e. informal writing describing emotions and opinions) in the Russian language RusNeuroPsych , containing metalabelling in the form of information about their authors (gender, age, psychological testing scores, brain laterality preferences). To the best of our knowledge, this is a unique corpus in terms of breadth of metadata about the authors. The corpus is freely available on RusProfiling Lab webpage. The collection and processing of the material to design the corpus, its composition and structure are considered. The possibilities of the application of RusNeuroPsych corpus in different domains of knowledge are analyzed.
Motivic Galois coaction and one-loop Feynman graphs

All Feynman integrals are examples of periods, and as such conjecturally carry an action of the motivic Galois group, or dually the coaction of the Hopf algebra of functions on the motivic Galois group. In this paper, we study this structure in the case of Feynman integrals associated to scalar one-loop Feynman graphs for a fixed dimension of space-time.
Learning By Collaborative Teaching: An Engaging Multi-Party CoWriter Activity

This paper presents the design of a novel and engaging collaborative learning activity for handwriting where a group of participants simultaneously tutor a Nao robot. This activity was intended to take advantage of both collaborative learning and the learning by teaching paradigm to improve children’s meta-cognition (perception of their own skills). Multiple engagement probes were integrated into the activity as a first step towards fostering long term interactions. As a lot of research targets social interactions, the goal here was to determine whether an engagement strategy focused on the task could be as, or more efficient than one focused on social interactions and participants’ introspection. To that effect, two engagement strategies were implemented. They differed in content but used the same multi-modal design in order to increase participants’ meta-cognitive reflection, once on the task and performances, and once on participants’ enjoyment and emotions. Both strategies were compared to a baseline by probing and assessing engagement at the individual and group level, along the behavioural, emotional and cognitive dimensions, in a between subject experiment with 12 groups of children. The experiments showed that the collaborative task pushed the children to adapt their manner of writing to the group, even though the adopted solution was not always correct. Furthermore, there was no significant difference between the strategies in terms of behaviour on task (behavioural engagement), satisfaction (emotional engagement) or performance (cognitive engagement) as the group dynamics had a stronger impact on the outcome of the collaborative teaching task. Therefore, the task and social engagement strategies can be considered as efficient in the context of collaboration.
Seed market liberalization, hybrid maize adoption, and impacts on smallholder farmers in Tanzania

Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a recent survey of smallholder maize farmers in two zones of Tanzania. Hybrid adoption rates are 48% and 13% in the North and East, respectively. Average net yield gains of hybrids are 50-60%, and there are also significant profit effects. Geographical disaggregation reveals that the benefits have mostly occurred in the North, which also explains higher adoption there. In the North, hybrid adoption caused a 17% increase in household living standards. We conclude that proprietary hybrids can be suitable for semi-subsistence farms and that seed market liberalization has generated positive socioeconomic developments.
Species richness of insect herbivore communities on Ficus in Papua New Guinea

Insect herbivores were sampled from the foliage of 15 species of Ficus (Moraceae) in rainforest and coastal habitats in the Madang area, Papua New Guinea. The collection included 13 193 individuals representing 349 species of leaf-chewing insects and 44 900 individuals representing 430 species of sap-sucking insects. Despite a high sampling intensity, the species accumulation curve did not reach an asymptote. This pattern was attributed to the highly aggregated distribution of insects on individual host trees. The number of insect species collected on a particular Ficus species ranged from 34 to 129 for leaf-chewing and from 51 to 219 for sapsucking insects. Two Ficus species growing on the seashore sustained less speciose insect communities than their counterparts growing in forest. For the forest figs, significant predictors of insect species richness included leaf palatability and leaf production for leaf-chewing insects (40% of the variance explained), and tree density and leaf expansion for sap-sucking insects (75%). The high faunal overlap among Ficus communities and the importance of local resources for insect herbivores suggest that highly specialized interactions between insect herbivores and Ficus in Papua New Guinea have not been conserved in evolutionary time. This is at variance with the dogma of old, extremely specialized and conservative interactions between insect herbivores and their hosts, providing numerous ecological niches in the floristically rich tropics.
A 53-year forcing data set for land surface models

[1] As most variables describing the state of the surface are not directly observable, we have to use land surface models in order to reconstruct an estimate of their evolution. These large-scale land surface models often require high-quality forcing data with a subdiurnal sampling. Building these data sets is a major challenge but an essential step for estimating the land surface water budget, which is a crucial part of climate change prediction. To study the interannual variability of surface conditions over the last half century, we have built a 53-year forcing data set, named NCC. NCC has a 6-hourly time step from 1948 to 2000 and a spatial resolution of 1° × 1°. It is based on the National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis project and a number of independent in situ observations. In this study we show the adjustments which need to be applied to the reanalysis and how they impact the simulated continental water balance. The model outputs are validated with the observed discharges of the world's 10 largest rivers to estimate the combined errors of the forcing data and the land surface model. The seasonal and interannual variations of these discharges are used for this validation. Five numerical experiments have been carried out. They used the forcing data sets obtained after each step of data adjustment and the forcing of the Global Soil Wetness Project 2 as inputs for the Organizing Carbon and Hydrology in Dynamic Ecosystems (ORCHIDEE) land surface model. The quality of forcing data is improved after each adjustment. The precipitation correction gives the most important improvement in the simulated river discharges, while the temperature correction has a significant effect only at high latitudes. The radiation correction also improves the forcing quality, especially in term of discharge amplitude. The NCC forcing data set can be used to study the water budget over many areas and catchment basins that have not been yet analyzed in this study. With its period of 53 years, NCC can also be used to evaluate the trends of terrestrial water storage in particular regions.
A Hedonic Pricing Model for German Wine Ein hedonisches Preismodell für Qualitätswein aus Deutschland

Abstract We develop a hedonic pricing model for German quality wine. Qual-ity indicators for 4,141 wines are sensory awards received at theannual German wine competition and the legally required qualitycategory as well as a set of control variables including regionalorigin, color, style, and their age at the time of judging. The dataconfirms that sensory quality awards have a significant and positiveprice impact. Moreover, we estimate significant relative differencesbetween quality categories, growing regions and most of the controlvariables. Key words wine, hedonic pricing models, reputation 1. Introduction Because any expert appraisal of sensorywine quality is based on subjective im-pressions, wine is also classified accord-ing to legally binding criteria and stan-dards that are measurable and verifiable.Such a notion of “quality” is outlined inwine laws and regulations. The EU winelaw assigns general conditions that applyto all wine-producing member states, buttakes common interests as well as na-tional differences into account. For ex-ample, the vineyard areas in the EU aredivided into climatic zones to help com-pensate for the climatic variations that influence wine pro-duction. Similarly, the EU wine law defines quality catego-ries that enable legally equivalent comparisons amongmember states. However, each member state is permitted todetermine the criteria and method of assessment necessaryto meet local (and EU) quality standards.In some countries, wine quality is closely tied to origin; i.e.the system is based on given conditions. Quality standardsvary considerably, depending on appellation of origin, andthe qualitative assessment is usually determined by regionalwine trade organizations. However, in Germany quality isconfirmed or denied by official testing. The quality in theglass rather than origin counts. The standards are largelyuniform and the assessment is determined through qualitycontrol testing. Regulations governing quality categoriesand testing are important components of the German wine law.Germany is the world’s sixth largest wine producer with atotal production of about ten million hectoliters. Germanwine is grown in 13 classified regions and renowned for itswhite varieties such as Riesling and Muller-Thurgau.Table 1 provides an overview of production by growingregion. Vineyard area and production quantity remainedrelatively steady over the last decade. However, there havebeen significant structural changes (DWI, 2001). In par-ticular, the proportion of red variety vineyards has grownfrom 16% to over 26%. Mass producing white varieties arenow declining and the production increasingly focuses onpremium quality wine (S

PIR Array Codes with Optimal PIR Rate

There has been much recent interest in Private information Retrieval (PIR) in models where a database is stored across several servers using coding techniques from distributed storage, rather than being simply replicated. In particular, a recent breakthrough result of Fazelli, Vardy and Yaakobi introduces the notion of a PIR code and a PIR array code, and uses this notion to produce efficient protocols. In this paper we are interested in designing PIR array codes. We consider the case when we have $m$ servers, with each server storing a fraction $(1/\omegaR)$ of the bits of the database; here $\omegaR$ is a fixed rational number with $\omegaR > 1$. We study the maximum PIR rate of a PIR array code with the $k$-PIR property (which enables a $k$-server PIR protocol to be emulated on the $m$ servers), where the PIR rate is defined to be $k/m$. We present upper bounds on the achievable rate, some constructions, and ideas how to obtain PIR array codes with the highest possible PIR rate. In particular, we present constructions that asymptotically meet our upper bounds, and the exact largest PIR rate is obtained when $1 < \omegaR \leq 2$.
Running title : Differential expression of duplicated binA / binB

Due to the self-produced binary toxins BinA/BinB, some Lysinibacillus sphaericus isolates exhibit high toxicity against mosquito larvae and are utilized in mosquito control programs. Previous whole genome sequencing revealed the presence of a large plasmid pBsph in L. sphaericus C3-41, which contains a 30.5-kb duplication of the genome including the binary toxin genes binA/binB. This was confirmed by Southern blot and qPCR experiments in this study. Mutants of L. sphaericus C3-41, bearing disruptions of the chromosomal-bin (C3-41ΔCab) or the plasmid-bin (C3-41ΔPab) and a plasmid cured strain G725, were generated. It was observed that the three mutants, especially that of C3-41ΔPab and G725, had lower mRNA level from the early to middle sporulation phase and expressed less binary toxin during the whole sporulation phase.

These results suggest that both chromosomaland plasmid-borne bin genes, especially the latter, contribute to the full toxicity of the wild strain. The study provides an important clue for the evolution and application of mosquitocidal L. sphaericus.
RFID Security and Privacy

The European Commission has published in May 2009 a recommendation “on the implementation of privacy and data protection principles in applications supported by radiofrequency identification”, which is designed to provide “guidance to Member States on the design and operation of RFID applications in a lawful, ethical and socially and politically acceptable way, respecting the right to privacy and ensuring protection of personal data. ” This recommendation requires RFID operators to conduct a “Privacy and Data Protection Impact Assessment” before any RFID application is deployed, and make its results available to the competent authority. The RFID recommendation is also designed to promote “information and transparency on RFID use”, in particular through the development of “a common European sign developed by European Standardisation Organisations, with the support of concerned stakeholders”, designed “to inform individuals of the presence of readers”. RFID PIA (Privacy and Impact Assessment) process aims to reach several objectives: • to favor "privacy by design" by helping data controllers to address privacy and data protection before a product or service is deployed, • to help data controllers to address privacy and data protection risks in a comprehensive manner, an opportunity to reduce legal uncertainty and avoid loss of trust from consumers, • to help data controllers and data protection authorities to gain more insight into the privacy and data protection aspects of RFID applications. The industry has proposed a RFID PIA framework which classifies a RFID application into 4 possible levels: Level 0: applications that do not process personal data and where tags are only manipulated by users, and which are rightly excluded from conducting a PIA. Level 1: applications where no personal data is processed, yet tags are carried by individuals. Level 2: applications which process personal data but where tags themselves do not contain personal data. Level 3: applications where tags contain personal data. If the RFID application level is determined to be 1 or above, the RFID operator is required to conduct a four part analysis of the application, with a level of detail that is proportionate to identified privacy and data protection implications. The first part is used to describe the RFID application. The second part allows highlighting control and security measures. The third part addresses user information and rights. The final part of the proposed PIA framework requires the RFID operator to conclude whether or not the RFID application is
Positively curved manifolds with symmetry

There are very few examples of Riemannian manifolds with positive sectionalcurvature known. In fact in dimensions above 24 all known examplesare diffeomorphic to locally rank one symmetric spaces. We give a partialexplanation of this phenomenon by showing that a positively curved, simplyconnected, compact manifold (M,g) is up to homotopy given by a rank onesymmetric space, provided that its isometry group Iso(M,g) is large. Moreprecisely we prove first that if dim(Iso(M,g)) iÝ 2 dim(M) . 6, then M is tangentially homotopically equivalent to a rank one symmetric space or M is homogeneous. Secondly, we show that in dimensions above 18(k +1)2 each M is tangentially homotopically equivalent to a rank one symmetric space, where k > 0 denotes the cohomogeneity, k = dim(M/Iso(M,g)).
FRITZ JOHN TYPE OPTIMALITY IN NONLINEAR

In this paper, we use a generalized Fritz John condition to derive optimality conditions and duality results for a nonlinear programming with inequality constraints, under weak invexity with respect to different (ηi)i assumption. The equivalence between saddle points and optima, and a characterization of optimal solutions are established under suitable generalized invexity requirements. Moreover, we prove weak, strong, converse and strict duality results for a Mond-Weir type dual. It is shown in this study, with examples, that the introduced generalized Fritz John condition combining with the invexity with respect to different (ηi)i are especially easy in application and useful in the sense of sufficient optimality conditions and of characterization of solutions.
MEASUREMENT OF THE MAGNITUDE OF FORCE APPLIED BY STUDENTS WHEN LEARNING A MOBILISATION

CORRESPONDENCE TO: E Smit Department of Physiotherapy, Faculty of Health Sciences, Stellenbosch University PO Box 19063 Tygerberg 7505 Tel: (021) 938 9300 Fax: (021) 931 7810 E-mail: es6@sun.ac. za for clinical reasoning regarding the diagnosis and the selection of techniques used to relieve pain, increase mobility and restore optimal function. Maitland (1993) graded passive mobilisation techniques from grade I to IV, according to their relationship with the onset of perceived resistance (R1) and the size of the oscillations (amplitude). Grading provides a benchmark for the following: the selection of a specific treatment plan; the re-assessment of the effects of treatment techniques; teaching purposes; communication and encouragement of continual development of palpatory skills (Chester and Watson 2000). Maitland (1993) defined a grade I as a small-amplitude movement performed at the beginning of range without moving into resistance (R1). According to Maitland (1993, p.97) a fitting descripABSTRACT: Passive accessory intervertebral movements (PAIVM’s) are frequently used by physiotherapists in the assessment and management of patients. Studies investigating the reliability of passive mobilisation techniques have shown conflicting results. Therefore, standardisation of PAIVM’s is essential for research and teaching purposes, which could result in better clinical management. In order to standardise graded passive mobilisation techniques, a reliable, easy-to-use, objective measurement tool must be used. The aim of this study was to determine whether it is necessary to quantify the magnitude of force applied when teaching a grade I central posteroanterior (PA) mobilisation technique (according to Maitland) on the cervical spine. An objective measurement tool (FlexiForceTM) was used to determine the consistency of force applied by third and fourth year physiotherapy students while performing this technique. Twenty thirdand 20 fourth year physiotherapy students (n=40) were randomly selected. Each subject performed a grade I central PA on sensors placed on C6 for 25 seconds. The average maximum grade 1 force applied by the third year students was significantly higher than the force applied by the fourth year students (p=0.034). There was a significantly larger variation in applied force among third years (p=0.00043). The results indicate that the current teaching method is insufficient to ensure inter-therapist reliability amongst students, emphasising the need for an objective measurement tool to be used for teaching students. The measurement tool used in this study is economical, easily applied and is an efficient method of measuring the magnitude of force. Further research is needed to demonstrate the reliability and validity of the tool to assist teaching and research in a clinical setting.
Feasibility Studies on Compressive Strength of Ground Coal Ash Geopolymer Mortar

Coal ash obtained from the Thermal Power plants consists of a major portion of Flyash and less amount of Bottom ash. As a major portion of the coal ash, fly ash has been recognized widely as a source material for geopolymers while the utilization of bottom ash has received very less attention owing to its coarser size.Hence to promote greater utilisation of bottom ash in construction sector, this work proposes the use of ground bottom ash in geopolymer mortar. The effect of molar ratio of SiO2 /Na2 O, Na2 SiO3 /NaOH ratio and curing mode were studied on compressive strength of coal ash geopolymer mortar. Molarity of sodium silicate solution was kept as 8M. Ambient curing and steam curing at 60oC was attempted. Test results indicate that Na2 SiO3 /NaOH of ratio 2 with SiO2 /Na2 O molar ratio 1 mortar achieved higher compressive strength under both ambient curing and steam curing.

Cogasification of Coal and Biomass: A Review

Recently, there has been significant research interest in cogasification of coal and various types of biomass blends to improve biomass gasification by reducing the tar content in the product gas. In addition, ash present in biomass catalyzes the gasification of coal. However, due to the fibrous nature of biomass and the large difference in gasification temperature of coal and biomass, cogasification in existing systems presents technical challenges. This paper documents research studies conducted on the cogasification of various types of coal and biomass using different types of gasifiers under various sets of operating conditions. In addition, the influence of cogasification on upstream and downstream processing is presented.
