A pr 2 01 8 Prepotentials for linearized supergravity

Linearized supergravity in arbitrary dimension is reformulated into a first order formalism which treats the graviton and its dual on the same footing at the level of the action. This generalizes previous work by other authors in two directions: 1) we work in arbitrary space-time dimension, and 2) the gravitino field and supersymmetry are also considered. This requires the construction of conformally invariant curvatures (the Cotton fields) for a family of mixed symmetry tensors and tensor-spinors, whose properties we prove (invariance; completeness; conformal Poincaré lemma). We use these geometric tools to solve the Hamiltonian constraints appearing in the first order formalism of the graviton and gravitino: the constraints are solved through the introduction of prepotentials enjoying (linearized) conformal invariance. These new variables (two tensor fields for the graviton, one tensor-spinor for the gravitino) are injected into the action and equations of motion, which take a geometrically simple form in terms of the Cotton tensor(-spinors) of the prepotentials. In particular, the equations of motion of the graviton are equivalent to twisted self-duality conditions. We express the supersymmetric transformations of the graviton and gravitino into each other in terms of the prepotentials. We also reproduce the dimensional reduction of supergravity within the prepotential formalism. Finally, our formulas in dimension five are recovered from the dimensional reduction of the already known prepotential formulation of the six-dimensional N = (4, 0) maximally supersymmetric theory.
Economic efficiency of small scale soyabean farmers in Central Agricultural Zone, Nigeria: A Cobb-Douglas stochastic frontier cost function approach

This study employed the Cobb-Douglas stochastic frontier cost function to measure the level of economic efficiency and its determinants in small scale soyabean production in Central Agricultural Zone of Nigeria. A multistage sampling procedure was used to select 485 soyabean farmers in the Zone, in 2010, from whom input-output data and their prices were obtained using the cost-route approach. The parameters of the stochastic frontier function were obtained using the maximum likelihood method. The result of the analysis showed that average economic efficiency was 52%. The study found age, farm size and household size to be negatively and significantly related to economic efficiency at 5 and 1%. Education, farming experience, access to credit and fertilizer use were significantly and positively related to economic efficiency. No significant relationship was found between economic efficiency and extension contact and membership of farmers’ association. It was recommended that policies that will increase farmers’ economic efficiency level be targeted at improving their educational levels and easy access to credit and fertilizer, while experienced farmers should be encouraged to remain in soyabean farming. Key words: Cobb-Douglas stochastic frontier cost function, economic efficiency, small scale soyabean farmers
Effect of training with partial blood flow restriction in older adults: a systematic review

Low-intensity training with blood flow restriction (BFR) has been suggested as an alternative to physical training for older adults. The present study aimed to review the literature regarding the effect of training with BFR for older adults. The search strategyconsisted of experimental studies aimed at verifying the effects of training with BFR on any outcome in older adults. An electronic search in PubMed / Medline, Bireme Scielo, Lilacs and Cochrane Library databases, published until December 2015 was conducted. Experimental studies that considered individuals aged 50 years and over published in English or Portuguese, were included. The Downs & Black scale was used to assess the methodological quality of articles. Of the 60 studies, 12 were included in the review. Training with BFR improved body mass, torque and muscle power; functional capacity; bone health; venous compliance; peak oxygen uptake; and blood flow; balance and overall performance. The methodological quality of studies had mean score of 16.2 points (SD = 1.6). The prescription of low-intensity exercises with BFR may be an alternative of training for older adults. However, future studies should address the methodological quality, especially external validity and power, the main gaps in articles reviewed in this study.
Routes, Exports, and Employment in Developing Countries: Following the Trace of the Inca Roads *

Domestic road infrastructure programs are often justified on the basis of their presumed positive effects on firms’ exports and accordingly on firms’ employment. In this paper we evaluate this policy claim for a developing country. In so doing, we take advantage of detailed geo-referenced data on firm-level trade and historical and current road infrastructure on Peru for the period 2003-2010. To identify the effects of interest we instrument recent changes in the road network with the pre-Columbian Inca road network. We find that improvements in transport infrastructure had a significant positive impact on firms’ exports and thereby on firms’ job growth –an increase of 6.4% and 5.1% in the average annual growth rate of exports and employment, respectively.
Explaining the Euro's Effect on Trade? Interest Rates in an Augmented Gravity Equation

If the Euro has boosted intra Euro-Area trade, what exactly in the new currency is responsible for such an effect? Most explanations focus on a decrease in exchange rate volatility or in transaction costs, receiving mixed empirical support. After briefly surveying the relevant literature, this paper points to a novel channel of transmission: the sharp decrease in real interest rates that accompanied the Euro. The argument is that lower interest rates spurred investment spending and manufacturing value added, as in Flam and Helpman (1987), and induced a greater number for firms to enter the export market, ultimately boosting trade. This phenomenon is captured in a simple model with fixed costs, where the number of firms or varieties supported in a market is endogenous. The model is used to augment the traditional trade gravity equation. In the end, empirical results are presented in support of the interest rate's role at explaining the "Rose effect".
Similarities between Playing World of Warcraft and CLIL

This article argues that playing World of Warcraft (WoW) and Content and Language Integrated Learning (CLIL) have a number of similar features. We base our argument on findings from three studies. The first (Sylven 2004/2010) is about CLIL and non-CLIL students at upper secondary level and aims to investigate what effect, if any, CLIL has on the incidental acquisition of vocabulary. The second (Sundqvist 2009) is about extramural English and aims to examine its potential
The impact of exercise intensity on mood state of participants in dance aerobics programs

The aim of the present study was to examine the effect of a single session dance aerobic program of high and moderate intensity on the psychological mood state of healthy adults. The study sample consisted of 136 adults, who took part in two group exercise programs: 1) high-intensity dance aerobic exercises (n = 59) and 2) moderate-intensity dance aerobic exercises (n = 77). The questionnaire used for data collection was the Profile of Mood States inventory (POMS), by McNair, Lorr and Droppleman (1971) modified for the Greek population by Zervas, Ekkekakis, Psychoundaki, and Kakkos (1993). The subjects filled in the questionnaire before and after participating in each program. The repeated measures ANOVA analysis showed that there was a statistically significant difference in the psychological mood state of the sample, before and after the subjects’ participation in both programs. More specifically, there was a decrease in tension, depression, aggressiveness and confusion and, on the contrary, an increase in energy, while fatigue was kept on the same level. It can be concluded that both dance aerobics programs positively enhance the participants’ mood state and can be used for the improvement of psychological mood of adults, offering, at the same time, a variety to aerobics classes.
Atmospheric Measurement Techniques Evaluation of turbulent dissipation rate retrievals from Doppler Cloud Radar

Turbulent dissipation rate retrievals from cloud radar Doppler velocity measurements are evaluated using independent, in situ observations in Arctic stratocumulus clouds. In situ validation data sets of dissipation rate are derived using sonic anemometer measurements from a tethered balloon and high frequency pressure variation observations from a research aircraft, both flown in proximity to stationary, ground-based radars. Modest biases are found among the data sets in particularly lowor high-turbulence regimes, but in general the radar-retrieved values correspond well with the in situ measurements. Root mean square differences are typically a factor of 4–6 relative to any given magnitude of dissipation rate. These differences are no larger than those found when comparing dissipation rates computed from tetheredballoon and meteorological tower-mounted sonic anemometer measurements made at spatial distances of a few hundred meters. Temporal lag analyses suggest that approximately half of the observed differences are due to spatial sampling considerations, such that the anticipated radar-based retrieval uncertainty is on the order of a factor of 2–3. Moreover, radar retrievals are clearly able to capture the vertical dissipation rate structure observed by the in situ sensors, while offering substantially more information on the time variability of turbulence profiles. Together these evaluations indicate that radar-based retrievals can, at a minimum, be used to determine the vertical structure of turbulence in Arctic stratocumulus clouds.
Attachment styles and relationship quality among young couples

This research was aimed to study the relationship between attachment style and relationship quality among young couples. A correlational research design was adopted to answer the objectives of this study. A total of 257 students of Universiti Malaysia Sarawak (UNIMAS), Sarawak participated in this study. Two types of questionnaire were used in this study; the Experience in Close Relationship (ECR) to measure the attachment styles, and Couples Satisfaction Index (CSI) to measure the relationship satisfaction of the couples. The results showed that there was a significant relationship between attachment style and relationship quality among the young couples in UNIMAS. Attachment avoidance and attachment anxiety had a significant effect on the relationship quality of the young couples. It is suggested for future studies to consider selecting the samples by using simple random sampling as the targeted population would be able to represent the whole population and the result would be more accurate. Keywords: Attachment avoidance; attachment anxiety
Age estimation of billfishes ( Kajikia spp.) using fin spine cross-sections: the need for an international code of practice

Fin spine ageing is the most common technique used to estimate age and growth parameters of large pelagic billfishes from the families Istiophoridae and Xiphiidae. The most suitable methods for processing and interpreting these calcified structures for age estimation have not been clearly defined. Methodological differences between unvalidated ageing studies are of particular concern for highly migratory species because multiple researchers in different regions of the world may conduct age estimates on the same species or stock. This review provides a critical overview of the methods used in previous fin spine ageing studies on billfishes and provides recommendations towards the development of a standardized protocol for estimating the age of striped marlin, Kajikia audax and white marlin, Kajikia albida . Three on-going fin spine ageing studies from Australia, Hawaii, and Florida are used to illustrate some of the considerations and difficulties encountered when developing an ageing protocol for highly migratory fish species. Particular areas of concern that may influence age and growth estimates included differences in fin spine selection, sectioning methods, criteria for identifying and measuring annuli, distinguishing false annuli, validation procedures, identification of the first annulus, and methods used to replace annuli lost due to vascularization of the fin spine core.
Presence of endoparasites in the Greek buffalo (Bubalus bubalis) from Northern Greece

This study was conducted in order to determine the presence of parasitic infections of the Greek buffalo (Bubalus bubalis) in the Prefecture of Serres, Northern Greece. During the period from February to October 2014, faecal samples from 110 buffaloes of the Greek buffalo breed (Bubalus bubalis), from 9 farms located in proximity to Lake Kerkini, in the Prefecture of Serres, Northern Greece, were examined, in order to find reproductive elements of parasites. Out of 110 faecal samples examined, 102 (92.73%) were found infected with reproductive elements (eggs, larvae, cysts and oocysts) of parasites. Specifically, the parasites found were: Eimeria spp. (40%), Entamoeba bovis (16.36%), Paramphistomum cervi (10%), Fasciola hepatica (16.36%), Dicrocoelium dendriticum (28.18%), Moniezia benedeni (27.27%), Toxocara vitulorum (11.82%), Strongylida (gastrointestinal nematodes) (31.82%) and lungworms (28.18%). The present study appears to be the first report of the detection of lungworms in buffaloes, in Greece.
Antiretroviral Toxicity Leading to a Medication Change in Multiple HIVClinics in Resource Limited Settings

Background: Toxicities that led to antiretroviral substitution in a multi-country treatment program were described. Methods: First line regimens included stavudine, lamivudine and nevirapine or efavirenz. Alternative therapy included zidovudine, tenofovir, efavirenz and lopinavir/ritonavir. Clinicians were trained to diagnose common antiretroviral side effects. Facilities had access to safety laboratory assays. Toxicity was detected clinically, and confirmed or monitored using specific laboratory assays where indicated. Results: Between 2004 and 2006, among 6,520 patients in Uganda, Kenya and Zambia, initiating antiretroviral therapy, toxicity-related substitutions were observed for stavudine 24.6%, zidovudine 13%, nevirapine 6.6%, efavirenz 3.4%, lopinavir/ritonavir 2% and tenofovir 0.7%. Mean time to switch ranged from 25 days for Lopinavir/ ritonavir, to 141 days for stavudine. Most common toxicities included neuropathy (stavudine), anemia (zidovudine), rash and liver toxicity (nevirapine). Conclusions: Toxicity rates in the study were comparable to reports in Food and Drug Administration (FDA) label package inserts and other smaller published reports in Africa and Asia. These toxicity rates could be used to inform drug forecasting for resource-limited settings. Comparably high tolerability of tenofovir and efavirenz may support their preferential use.
Enhanced window sampling using CUDA enabled devices

Diese Masterarbeit untersucht die Anwendbarkeit von CUDA Graphikkarten in mod- ernen Physik Simulationen. Zwei bestehende CUDA Projekte, die man auf der NVIDIA Website finden kann, und eine Publikation von J.A. van Meel dienen als die Inspiration dieses Unterfangens. Das untersuchten Algorithmen sind der Ausgangspunkt der detaillierten Analyse der Nukleationsmechanismen von unterkuhlten Lennard-Jones Flussigkeiten. Die Voraussagen der klassischen Nukleationstheorie werden durch die Messung der freien Energie als Funktion der Groye der kristallinen Kerne, die sich in der unterkuhlten Flussigkeit bilden, bestatigt. Die Arbeit von Wolfgang Lechner in seiner Analyse des "Gaussian Core Modells" dient als Anhaltspunkt dieser Arbeit, wobei Frenkel et. al. und Daniele Moroni als die ursprunglichen Architekten dieser Methoden gelten. Um die Nukleation von unterkuhlten Flussigkeiten zu untersuchen, wurden, zusatzlich zu einem Monte Carlo Simulationsalgorithmus, "Bond Order Analysis" und "Um- brella Sampling" Algorithmen in CUDA entwickelt. Die Komplexitat des Systems und die zu seiner Untersuchung notwendigen Algorithmen sind ein ausreichend guter Test, um die Brauchbarkeit von CUDA GPGPUs in modernen Physik Simulationen zu evaluieren. Unter Verwendung einer NVIDIA Tesla C870 GPGPU konnten trotz der Einschrankungen durch die "floating point" Genauigkeit der Graphikkarte mit der Literatur ubereinstimmende Resultate produziert werden. Diese Resultate wurden um ungefahr einen Faktor 10 schneller errechnet als auf einem Intel Core Duo 6600 Rechner. In diesem Fall ist damit die Leistung einer solchen Graphikkarte vergleichbar mit der Leistung eines Clusters von Intel Core Duo 6600 Rechnern.
Transport Modelling During Preparation of General Plans in Big Cities: Reasons and Challenges

Rapidly growing mobility of people in European cities attaches greater importance to the sustainable developmentconcept. The dynamics of European cities are however different. Cites such as Lithuanian, Slovakian and Polishones will rapidly increase traffic flows and car ownership at fast pace. Also in most of Western Europe, even if at lowerrates, private mobility is increasing. In some cities, however, car use and car ownership are finally decreasing, alsothanks to policies implemented. Of course, an increase of traffic flows poses problems in terms of street space, pollutionand liveability of cities. Sustainable integration of all kinds of transport into the urban development process is one ofthe most effective actions in the hands of city planners. The coordination between the planning of residential and businessdevelopment areas and the expansion of public transport and its hierarchical integration is however a difficult butnecessary exercise. Transport modelling tools, in particular, need important advancements to integrate transport andland use in simulations. This article analyses the main challenges in the use of transport models to support the constructionof city plans by means of two case studies of Milan and Vilnius. The analysis deals both with traditional aspects,such as the proper simulation of multimodal choices, the level of detail of zoning, the issues associated to the simulationof traffic management policies. Then, we will focus on two aspects still open: the integration of transport modelling andeconomic assessment or ranking of actions, and the inclusion of land use changes in the modelling.

Study about socio-economic status and calf rearing management practices adopted by cattle keepers of Western Rajasthan, India

The present investigation was conducted to find out the socio-economic status and various calf rearing management practices adopted by cattle keepers of Western Rajasthan. 320 respondents from Barmer and Jalore districts of Western Rajasthan were selected. It was found that only 54.69 per cent of respondents were literate.69. 06 per cent of the respondents had small herd size while 60 per cent of respondents had small land holding.Regarding calf management practices, 89.06 per cent of the respondents cleaned and trimmed hooves of the calf after birth. Majority of the respondents did not cut naval cord of calf. It was found that 53.13 per cent of the respondents allowed suckling calf up to 6 month and 95 per cent of cattle keepers were not performing de-worming of calves.It was concluded that cattle keepers of Western Rajasthan were not well aware about importance of improved calf-rearing management practices.
Individual Variables, Attitudes towards English and Being a Teacher: A study on Prospective Teachers

The achievement in learning a foreign language depends not only on cognitive factors such as intelligence, aptitude etc., but also on affective factors such as attitude and motivation. As the main branch of prospective teachers of English is teaching a language, their attitudes towards English and towards being a teacher are of vital importance in their future careers. The purpose of this descriptive study is to determine whether the attitudes of the students of English Language Teaching Department towards English affect their attitudes towards being a teacher of English and whether the students’ attitudes indicate significant differences with regard to individual variables such as gender, class, the types of High Schools from which they have graduated, their socio-economic background, and whether there is a teacher in their family. The sample group of the study were composed 540 prospective English teachers of the first, second, third and fourth year students of the Department of English Language Teaching at Buca Faculty of Education at Dokuz Eylul University, Izmir. For data collection, personal information sheet, the scale for attitudes towards English developed by Altunay (2002) (Alpha Reliability Coefficient: 0.96) and the scale for attitudes towards Being a Teacher developed by Semerci (1999) (Alpha Reliability Coefficient: 0.68) were used. The results indicate that the more positive the students’ attitudes towards English are, the more positive the students’ attitudes towards teaching profession are. Furthermore, when attitudes towards English and towards being a teacher are compared it is indicated that the students’ attitudes towards English are a little bit higher.
Constraints on variation in α and me from WMAP 7-year data

Aims. We update the constraints on the time variation of the fine structure constant α and the electron mass m e , using the latest CMB data, including the 7-yr release of WMAP. Methods. We made statistical analyses of the variation of each one of the constants and of their joint variation, together with the basic set of cosmological parameters. We used a modified version of CAMB and COSMOMC to account for these possible variations. Results. We present bounds on the variation of the constants for different data sets, and show how results depend on them. When using the latest CMB data plus the power spectrum from Sloan Digital Sky Survey LRG, we find that α/α 0 = 0.986 ± 0.007 at 1-σ level, when the 6 basic cosmological parameters were fitted, and only variation in α was allowed. The constraints in the case of variation of both constants are α/α 0 = 0.986 ± 0.009 and m e /m e0 = 0.999 ± 0.035. In the case of only variation in m e , the bound is m e/ m e0 = 0.964 ± 0.025.
A Multi-wavelength Analysis of Binary-AGN Candidate PSO J334.2028+01.4075

We present an analysis of the first Chandra observation of PSO J334.2028+01.4075 (PSO J334), targeted as a binary-AGN candidate based on periodic variations of the optical flux. With no prior targeted X-ray coverage for PSO J334, our new 40 ks Chandra observation allows for the opportunity to differentiate between a single- or binary-AGN system, and if a binary, can characterize the mode of accretion. Simulations show that the two expected accretion disk morphologies for binary-AGN systems are (i) a “cavity,” where the inner region of the accretion disk is mostly empty and emission is truncated blueward of the wavelength associated with the temperature of the innermost ring, or (ii) “minidisks,” where there is substantial accretion from the circumbinary disk onto one or both of the members of the binary, each with their own shock-heated thin-disk accretion system. We find the X-ray emission to be well-fit with an absorbed power law, which is incompatible with the simple cavity scenario. Furthermore, we construct an SED of PSO J334 by combining radio through X-ray observations and find that the SED agrees well with that of a normal AGN, which is most likely incompatible with the minidisk scenario. Other analyses, such as those locating the quasar on IR color–color diagrams and analyzing the quasar mass predicted by the fundamental plane of black hole activity, further highlight the similarity of PSO J334 with respect to normal AGNs. On the multi-wavelength fronts we investigated, we find no evidence supporting PSO J334 as a binary-AGN system, though our analysis remains insensitive to some binary configurations.
