The polysemy of a social signal

The work analyses the head nod, a down-up movement of the head, as a polysemic social signal, that is, a signal with a number of different meanings which all share some common semantic element. Based on the analysis of 100 nods drawn from the SSPNet corpus of TV political debates, a typology of nods is presented that distinguishes Speaker’s, Interlocutor’s and Third Listener’s nods, with their subtypes (confirmation, agreement, approval, submission and permission, greeting and thanks, backchannel giving and backchannel request, emphasis, ironic agreement, literal and rhetoric question, and others). For each nod the analysis specifies: 1. characteristic features of how it is produced, among which main direction, amplitude, velocity and number of repetitions; 2. cues in other modalities, like direction and duration of gaze; 3. conversational context in which the nod typically occurs. For the Interlocutor’s or Third Listener’s nod, the preceding speech act is relevant: yes/no answer or information for a nod of confirmation, expression of opinion for one of agreement, prosocial action for greetings and thanks; for the Speaker’s nods, instead, their meanings are mainly distinguished by accompanying signals.

Making conservation tillage conventional, building a future on 25 years of research: research and extension perspective.

Although no-till (NT) has shown numer ous advantages over conventional tillage methods, the technology has shown r elatively slow adoption rates in many r egions of the world. In this paper , some of the r easons for slow adoption are analyzed. Mindset is pr obably among the biggest obstacles to expanded no-till use. Knowledge is also among the main constraints to expanded NT adop­ tion. Although r esearch has generated copious knowl­ edge, this knowledge is often not r eaching the farmer . Sometimes conditions for the utilization of technology ar e not met. Technology diffusion investigations show that farmer-to-farmer extension is one of the most ef fective ways of achieving rapid adoption of innovations. A greater effort has to be made in cr eating societal awar e­ ness of the many positive effects of NT , not only for farmers themselves but for society as a whole. Resear ch priorities should be dir ected towards intensifying work with green manure cover crops, crop rotations, biological control of diseases, pests and weeds, soil biology , adapta­ tion of NT to site-specific conditions using a systems approach and on-farm r esearch. The technology should also be developed fur ther for small farmers and r esearch should be done with a gr eater variety of cr ops in order to widen the possibilities of cr op rotations. Finally a gr eater effort has to be made in analyzing the economics of NT in a systems appr oach, taking all on-farm and off-farm benefits of the system into consideration.

Stability and Bifurcation Analysis of a Modified Epidemic Model for Computer Viruses

We extend the three-dimensional SIR model to four-dimensional case and then analyze its dynamical behavior including stability and bifurcation. It is shown that the new model makes a significant improvement to the epidemic model for computer viruses, which is more reasonable than the most existing SIR models. Furthermore, we investigate the stability of the possible equilibrium point and the existence of the Hopf bifurcation with respect to the delay. By analyzing the associated characteristic equation, it is found that Hopf bifurcation occurs when the delay passes through a sequence of critical values. An analytical condition for determining the direction, stability, and other properties of bifurcating periodic solutions is obtained by using the normal form theory and center manifold argument. The obtained results may provide a theoretical foundation to understand the spread of computer viruses and then to minimize virus risks.
Illumination of Shadowing Behavior in Individuals with Alzheimer’s Disease: Proximity-Seeking? As Life Becomes the “Strange Situation”

The purpose of this paper is to suggest an intrapersonal help for caregivers through proposing a model for understanding shadowing behavior. This model is based on Bowlby’s (1973) discussion of attachment and related concepts such as proximityseeking, the “strange situation”, and the secure base. Building on Bowlby’s discussion, Mikulincer and Shaver (2008) developed a visual representation of the dynamics of adult attachment, herein modified and explicated according to its proposed relationship to caregivers and care recipients living with Alzheimer’s disease. A potential underlying brain-based rationale, is also presented
Antioxidant Activity and Nutrient Content of Ethanol and Hot-Water Extracts of Citrus unshiu Pomace

The objective of this study was to evaluate the effect of extraction methods on the antioxidant activity of Citrus unshiu pomace. For this purpose, two kinds of citrus pomace (CP)s, whole fruit CP and pulp CP, were used for preparing the extracts with hot water or 70% ethanol. It is well-known fact that whole fruit CP has more calories and carbohydrates, although moisture content is higher in pulp CP. Further, whole fruit CP extracts have higher levels of total phenolic contents compared to CP extracts. In addition, DPPH and alkyl radical scavenging activities were also higher in whole fruit CP, especially in ethanolic extracts. Our results based on liquid chromatography-mass spectrometer showed that 70% ethanolic extract of whole fruit CP has the maximum levels of nobiletin and tangeretin contents. The levels of naringin, which is known as an antioxidant flavonoid, was determined only in the 70% ethanolic extract of whole fruit CP. This result, however, is consistent with the observed DPPH and alkyl radical scavenging activities. We had also performed a gas chromatography analysis that showed all the four extracts contained the compound hydroxymethyl furfural. Significantly, this compound has been reported to have antioxidant activity. Taken together, findings of this study indicate that ethanolic extraction of whole fruit CP is a good source of antioxidant compounds and hence the same could be utilized as an important method to obtain such beneficial compounds on an industrial scale.

Ethno-medicobotany of some tribal communities of Bankura district, West Bengal, India.

Investigation and documentation of the status of medicinal plants and associated knowledge was conducted in Taldangra block situated at south-western part of Bankura district. Data was collected and evaluated with a questionnaire survey, semi-structured interviews, field observations and vegetation surveys. 16 medicinal plant species used to treat 40 different ailments were recorded. Leaves are the most commonly collected plant parts for medicinal purposes. Much of the ethno-medicinal knowledge is concentrated in elderly members of the community. The medicinal plants are facing threats from agricultural expansion, wood extraction and overgrazing as informed by the local authorities. Consequently, medicinal plant resources are declining with time. The study aims to assess the contribution of nonconventional medicinal plants towards community health care. A total of 62 knowledge holders from the tribal community were interviewed and medicinal uses for 16 plants were recorded. The study illustrates that medicinal plant diversity is important for community health care, which in turn, ensures conservation, awareness creation towards sustainable utilization and management of these medicinal plants diversity.
Effect of Supplementing Spirulina on Live Performance, Carcass Composition and Meat Quality of Japanese Quail

This study was conducted to evaluate the effects of different levels of Spirulina ( Arthrospira platensis ) inclusion in feed on live performance, carcass composition and meat quality of Japanese quails during growing stage to identify the best inclusion range for Japanese quails without affecting the growth and carcass parameters. Three hundred Japanese quails of 15 days of age were used in this experiment, randomly divided into 5 groups with 3 replication comprised of 30 males and 30 females. The quails were fed with a basal diet as a control and 4 levels of Spirulina inclusion diet 1, 2, 4 and 8 %. Diets were fed to birds from 15 days to 35 days of age. Body weight gain (BWG), Feed intake (FI), Feed conversion ratio (FCR) and Mortality rate (MR) were recorded weekly during the experiment. Carcass composition and meat quality tests were done after slaughtering. BWG, FI, FCR and MR were significantly different (p < 0.05) in the experiment. Carcass composition was found to be significantly different in the leg percentage (p < 0.05). Meat color and meat shear force value were also found to differ significantly (p < 0.05) with the Spirulina inclusion diet showing a better result than the control. Therefore, the result of this experiment suggests that diets up to 4 % of Spirulina achieve the best live performance, carcass composition and meat quality. doi: 10.14456/WJST.2016. 8

A Statistically-Based Low-Level Cloud Scheme and Its Tentative Application in a General Circulation Model

In this study, a statistical cloud scheme is first introduced and coupled with a first-order turbulence scheme with second-order turbulence moments parameterized by the timescale of the turbulence dissipation and the vertical turbulent diffusion coefficient. Then the ability of the scheme to simulate cloud fraction at different relative humidity, vertical temperature profile, and the timescale of the turbulent dissipation is examined by numerical simulation. It is found that the simulated cloud fraction is sensitive to the parameter used in the statistical cloud scheme and the timescale of the turbulent dissipation. Based on the analyses, the introduced statistical cloud scheme is modified. By combining the modified statistical cloud scheme with a boundary layer cumulus scheme, a new statistically-based low-level cloud scheme is proposed and tentatively applied in NCAR (National Center for Atmospheric Research) CCM3 (Community Climate Model version 3). It is found that the simulation of low-level cloud fraction is markedly improved and the centers with maximum low-level cloud fractions are well simulated in the cold oceans off the western coasts with the statistically-based low-level cloud scheme applied in CCM3. It suggests that the new statistically-based low-level cloud scheme has a great potential in the general circulation model for improving the low-level cloud parameterization.
Biotransformation of Uranium Compounds in High Ionic Strength Brine by a Halophilic Bacterium under Denitrifying Conditions

We investigated the transformations of uranyl nitrate, uranyl citrate, uranyl ethylenediaminetetraacetate (U-EDTA), and uranyl carbonate by a denitrifying halophilic bacterium, Halomonassp. (WIPP1A), isolated from the Waste Isolation Pilot Plant (WIPP) repository. The addition of uranyl nitrate, uranyl citrate, or uranyl EDTA to the brine or bacterial growth medium resulted in the precipitation of uranium. Extended X-ray absorption fine structure (EXAFS) analysis of the precipitates formed in the brine and in the growth medium were identified as uranyl hydroxide [UO 2( OH) 2 ] and uranyl hydroxophosphato species [K(UO 2 ) 5 (PO 4 ) 3( OH) 2 . nH 2 O], respectively. Dissolution of the uranium precipitate was concomitant with the growth of the bacteria under anaerobic conditions. The UV-vis spectra of the culture medium during growth showed that a uranyl dicarbonate complex [UO 2 (CO 3 ) 2 ] 2- was formed due to CO 2 production from the metabolism of the carbon source succinate. The bacterium completely metabolized the citrate released from the uranyl citrate complex but not the EDTA released from the U-EDTA complex. Adding uranyl carbonate to the growth medium caused no changes in the uranium speciation due to bacterial growth. Uranyl carbonate was not biosorbed by the growing culture nor by washed resting cells suspended in 20% NaCl brine (3.4 M) because the complex was either neutral or anionic. Our results demonstrate that bacterial activity can enhance the dissolution of uranium phosphate by forming uranyl carbonate species.

SCHREYER HONORS COLLEGE DEPARTMENT OF BIOBEHAVIORAL HEALTH AN ANALYSIS OF THE EFFICACY OF THE HEALTHY BODIES PROJECT ON INCREASING FOOD LITERACY IN PRESCHOOL CHILDREN

The goal of the Healthy Bodies Project is to reduce rates of childhood obesity. The project aims to achieve this through a nutrition intervention targeted at 3-5-year-old low-income preschool children in Central Pennsylvania. This 28-week intervention works to increase the children’s food literacy and willingness to try new foods. This study measured improvements in food literacy over the course of the program through food literacy assessments that were conducted at the beginning and end of the program during the 2015-2016 school year. Trained research assistants conducted the assessments during one visit per classroom for pre-assessments, and one visit for post-assessments. Descriptive statistics were also generated to see if there was a relationship between how much a score increased in a classroom and the frequency with which a teacher used the supplied and recommended lesson tools, which included a mystery bag, flashcards, a song, and supplementary activities. Overall, there was a statistically significant improvement in food literacy scores after the program. The results indicate that greater use of the learning tools was not significantly related to the increase in children’s food literacy.
Optimisation of a Kalina cycle for a central receiver solar thermal power plant with direct steam generation

: Central receiver solar thermal power plants are regarded as one of the promising ways to generate electricity in near future. They offer the possibility of using high temperatures and pressures to achieve high efficiencies with standard power cycles. A direct steam generation approach can be used for such plants for improved performance. This approach can also be combined with using advanced power cycles like the Kalina cycle, which uses a zeotropic mixture of ammonia and water instead of pure water as the working fluid. This paper presents the optimisation of a particular Kalina cycle layout for a central receiver solar thermal power plant with direct steam generation. The variation in the cycle performance with respect to the turbine inlet ammonia mass fraction and pressure and a comparison of the initial investment with that of the basic Rankine cycle are also presented. Only high live steam conditions (temperature equal to 500 °C and pressure over 100 bar) were considered. The optimisation was performed using genetic algorithm. The results suggest that the optimum solutions for different turbine inlet ammonia mass fractions for the Kalina cycle occur at significantly different separator inlet conditions. Some of the Kalina cycle configurations can achieve similar or better cycle efficiency than the basic Rankine cycle but at a loss of the net electrical power output. The cost analysis suggests that some Kalina cycle configurations could have lower initial investment costs but only at higher turbine inlet pressure and inherently complex plant layouts as compared with the Rankine cycle.
MODAL ANALYSIS PROCEDURE USING COMPLEX LEFT AND RIGHT EIGENVECTORS OF NON-PROPORTIONALLY DAMPED STRUCTURES

Abstract. In the general case of non-proportionally damped structural model the associated quadratic eigenvalue problem leads to complex eigenvalues and eigenvectors. The modal decomposition of the equations of motion is usually to be performed in complex space. In this paper are presented possible variants of a general method [2] [5] for modal transformation of damped multi-degree-of-freedom-systems (MDOFS) with non-modal symmetric damping matrix. The assembly of a modal transformation matrix in real space is based either on the conjugated complex left eigenvectors, or on the right eigenvectors, or on a combination of the left and right eigenvectors of the system. The eigenvector normalization can be performed with respect to the general mass or to the general stiffness matrix. The equations of motion are stated in state-space formulation. The developed real-space modal transformation matrix is always built by a combination of two complex transformations. Analytically expressions for all presented variants of the modal transformation basis are developed be the aid of computer algebra software. Those formulas operate with the real and the imaginary parts of the eigenvectors and the associated eigenvalues. All variants of the suggested modal procedure retain the common advantages of the classic modal decomposition of the equations of motion. The vibrations of a rotor blade of a wind turbine subjected to wind thrust loads have been calculated in two variants to demonstrate the performance of the presented modal analysis procedures. The initial computation of the complex eigenvalue solution of the FEM beam model and all subsequent computations are done by the aid of computer algebra software. The suggested procedures can be applied in structural systems containing different damping and energy-loss mechanism in various parts of the structure, described by non-proportional damping matrix.
lyphosate effects on diseases of plants

Glyphosate, N-(phosphonomethyl)glycine, is the most extensively used herbicide in the history of agriculture. Weed management programs in glyphosate resistant (GR) field crops have provided highly effective weed control, simplified management decisions, and given cleaner harvested products. However, this relatively simple, broad-spectrum, systemic herbicide can have extensive unintended effects on nutrient efficiency and disease severity, thereby threatening its agricultural sustainability. A significant increase in disease severity associated with the wide spread application of the glyphosate herbicide can be the result of direct glyphosate-induced weakening of plant defenses and increased pathogen population and virulence. Indirect effects of glyphosate on disease predisposition result from immobilization of specific micronutrients involved in disease resistance, reduced growth and vigor of the plant from accumulation of glyphosate in meristematic root, shoot, and reproductive tissues, altered physiological efficiency, or modification of the soil microflora affecting the availability of nutrients involved in physiological disease resistance. Strategies to ameliorate the predisposing effects of glyphosate on disease include judicious selection of herbicide application rates, micronutrient amendment, glyphosate detoxification in meristematic tissues and soil, changes in cultural practices to enhance micronutrient availability for plant uptake, and biological amendment with glyphosate-resistant microbes for nitrogen fixation and nutrient availability. Given that recommended doses of glyphosate are often many times higher than needed to control weeds, we believe the most prudent method to reduce the detrimental effects of glyphosate on GR crops will be to use this herbicide in as small a dose as practically needed. Such a frugal approach will edisp not only curtail disease pr
