An Enlarged Analysis of the Asymptotic Compensation Problem for a Class of Disturbed Systems

This work concerns an enlarged problem of the asymptotic compensation for a class of disturbed systems. It consists to study, with respect to the output of the system and a given tolerance zone C, the possibility to reduce asymptotically the effect of any disturbance by bringing back the observation in the zone C. Under convenient hypothesis, we prove the existence and the unicity of the optimal control ensuring this compensation and we show how to find it.
Bunch exposure to direct solar radiation increases ortho-diphenol anthocyanins in Northern Italy climatic condition

Aims: Berry anthocyanin contents were studied in eight different field experiments involving various grapevine (Vitis vinifera L.) cultivars (Syrah, Croatina, Sangiovese, Nebbiolo, Nebbiolo Rose, Carmenere and Cannonau) in a variety of sites located in Northern Italy.Methods and results: In each experiment, global irradiance was reduced by approximately 95% by applying specially designed boxes to selected bunches before the onset of ripening. Variations in anthocyanin accumulation and profile were studied on sun exposed and shaded bunches. Exposed bunches were subjected to less favorable temperatures for biosynthetic metabolism than shaded bunches, due to frequent excessive temperatures around noon.Conclusions: Exposure to direct solar radiation induced an earlier and faster anthocyanin accumulation and a higher anthocyanin concentration across all the experiments, at least from veraison to mid ripening. In fact, the light induced elevated rate of anthocyanin accumulation did not always result in a higher anthocyanin content at grape maturity. In the cultivars with a relatively high proportion of acylated forms, sun exposure resulted in a relative increase in the quantities of non-acylated glucoside forms, while the acylation profile of cultivars that generally had a lower proportion of acylated forms was only minimally influenced by sun exposure.Significance and impact of the study: Akey observation resulting from anthocyanin profiling is the strong positive correlation between light exposure and increases in the percentage of delphinidin-, cyanidin- and petunidin-3-monoglucoside, that is, anthocyanins containing an ortho-dihydroxyl group.
Analysis of Formation Mechanism of Revisit Intention: Data from East China

The paper discusses the factors of revisit intention, and constructs an Extended Model of TPB which contains the variables of attitude, customer’s value etc. Based upon the literature review, the paper constructs the measurement of these factors. The structured survey is adapted to encompass four different destination types and the data is analyzed through SEM to research the formation mechanism of revisit intention. The results demonstrate that subjective norm, behavior control perception, attitude, past behavior, destination image, value of tourists and other variables have significant influence on revisit intention. Attitude and customer’s value are the mediator variables in the mode, and they also have significant influence on revisit intention. Other variables have significant effects or have indirect influence on revisit intention.

When geography matters: International diversification and firm performance of Spanish multinationals

This paper studies how the nature and shape of the relationship between inter- national diversification (ID) and performance (P) may vary according to a firm’s geographical focus of internationalization. Using a sample of Spanish multinational firms for the 2004—2012 period we find an M-shaped relationship. However, significant differences are found when the different geographical foci of internationalization are considered. Strong support is found when firms adopt a regional focus (an inverted S-curve when the ID measure refers to the number of foreign countries and an M-curve when it refers to the size of the network of foreign sub- sidiaries), a biregional focus (an S-curve) and a semiglobal focus (an inverted S-curve but also an M-curve with foreign subsidiaries). These findings and their pattern suggest the critical impor- tance of the country of origin and the geographical focus of internationalization in explaining the relationship between ID—P.

On Differential Rotation and Overshooting in Solar-like Stars

We seek to characterize how the change of global rotation rate influences the overall dynamics and large-scale flows arising in the convective envelopes of stars covering stellar spectral types from early G to late K. We do so through numerical simulations with the ASH code, where we consider stellar convective envelopes coupled to a radiative interior with various global properties. As solar-like stars spin down over the course of their main sequence evolution, such a change must have a direct impact on their dynamics and rotation state. We indeed find that three main states of rotation may exist for a given star: anti-solar-like (fast poles, slow equator), solar-like (fast equator, slow poles), or a cylindrical rotation profile. Under increasingly strict rotational constraints, the last profile can further evolve into a Jupiter-like profile, with alternating prograde and retrograde zonal jets. We have further assessed how far the convection and meridional flows overshoot into the radiative zone and investigated the morphology of the established tachocline. Using simple mixing length arguments, we are able to construct a scaling of the fluid Rossby number , which we calibrate based on our 3D ASH simulations. We can use this scaling to map the behavior of differential rotation versus the global parameters of stellar mass and rotation rate. Finally, we isolate a region on this map (Rof ≳ 1.5–2) where we posit that stars with an anti-solar differential rotation may exist in order to encourage observers to hunt for such targets.
Prediction of topsoil texture through regression trees and multiple linear regressions.

Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear Regressions - MLR) and the ability of these tools to predict mineral fraction content under a wide variability of landscapes. The study site was the entire Guapi-Macacu watershed (1,250.78 km²) in the state of Rio de Janeiro in the Southeast region of Brazil. Terrain attributes and remote sensing data (with 30 m of spatial resolution) were used to represent landscape co-variables selected as an input in predictive models in order to develop the explanatory variables. The selection of sampling sites was based on the Latin Hypercube algorithm. A representative set of one hundred points with feasible field access was chosen. Different input databases were tested for prediction of mineral fraction content (harmonized and original data). The Spline algorithm was used to harmonize data according to the GlobalSoil.Net consortium standards. The results showed better performance from the RT models, using input from an average of six covariates; the simplest MLR model used twice as many input variables, creating more complex models without gaining precision. Furthermore, better R² values were obtained using RT models, irrespective of harmonization of soil data. The harmonized dataset from the 0.00-0.05 and 0.05-0.15 m layers, in general, presented better results for the clay and silt, with R2 values of 0.52 (0.00-0.05 m) and 0.69 (0.05-0.15 m), respectively. Prediction of sand content showed better results when the original depth data was used as an input, although all regression tree models had R2 values greater than 0.52. The RT models provided a better statistical index than MLR for all predicted properties; however, the variance between models suggests similarity of performance. Regarding harmonization of soil data, both input databases (harmonized or not) can be used to predict soil properties, since the variance of model performance was low and generalization of the soil maps showed similar trends. The products obtained from the digital soil mapping approach make it possible to integrate the factor of uncertainties, providing easier interpretation for soil management and land use decisions.
On the modelling and synthesis of conversational speech

In this paper we discuss some preliminaries for modelling and synthesis of conversational speech basing ourselves first and foremost on insights gained within the Swedish GROG project (Carlson et al., 2002). Speech synthesis systems developed so far generate speech mostly modelled on read-aloud data. The next step, to synthesize conversational speech is a great challenge and an important endeavour which requires an understanding of how speech, and prosody in particular, is continuously produced. One important application of such knowledge is a more appropriate model of how speech synthesis should be generated in speech based conversational systems. Research along this line would have to lean on insights on cognitive and linguistic processing as well as phonetics and speech technology. As far as cognitive-linguistic processing concerns, there are today various efforts aiming at a deeper understanding of the shaping of spontaneous monologue and dialogue speech. Clark and colleagues, for example, have studied the interactions between linguistic-prosodic and cognitive processing in a number of studies and their commit-and-restore model (Clark and Wasow, 1998) outlining these interactions has had a great influence in speech research. Besides the current GROG project this interest in speech and language processing is also reflected in the Swedish research project The role of function words in spontaneous speech processing (see Horne et al., 2003, 2004).
EXPLORING THE FACTORS AFFECTING EMPLOYEES’ ADOPTION AND USE OF INNOVATION

This paper explores the factors affecting innovation adoption by individual employees within an organization in Australia. Following a qualitative research approach, this paper uses a series of in-depth interviews and focus group discussions involving academic and administrative employees at a tertiary educational institution in Australia. The qualitative approach is adopted to have a deeper insight into the complexities and dynamism associated with the factors influencing innovation adoption process in organizational settings. The findings of this research highlight the need for broadening an understanding of the key factors affecting employee’s decisions to uptake the adoption of innovation. The results provide important clues for comprehending the factors influencing and determining the employee’s adoption and continued use of innovation in the work environment. In the face of the current trend towards end-user applications of technological innovation, the results suggest some guidelines for management toward effective and efficient adoption and use of innovation in organizational settings. This paper has highlighted the above findings and their implications for management practices related to innovation management in an Australian organizational setting. This paper also identifies possible limitations and future research potential in the relevant field.
A new bound K2/3+ɛ for Rankin-Selberg ℒ-functions for Hecke congruence subgroups

Let f be a holomorphic Hecke eigenform for Γ0(N ) of weight k, or a Maass eigenform for Γ0(N ) with Laplace eigenvalue 1/4 + k. Let g be a fixed holomorphic or Maass cusp form for Γ0(N ). A subconvexity bound for central values of the Rankin-Selberg L-function L(s, f ⊗ g) is proved in the k-aspect: L(1/2+ it, f ⊗ g) N ,g,t,e k, while a convexity bound is only k. This new bound improves earlier subconvexity bounds for these Rankin-Selberg L-functions by Sarnak, the authors, and Blomer. Techniques used include a result of Good, spectral large sieve, meromorphic continuation of a shifted convolution sum to −1/2 passing through all Laplace eigenvalues, and a weighted stationary phase argument.
Atmospheric Measurement Techniques An investigation of atmospheric temperature profiles in the Australian region using collocated GPS radio occultation and radiosonde data

GPS radio occultation (RO) has been recognised as an alternative atmospheric upper air observation technique due to its distinct features and technological merits. The CHAllenging Minisatellite Payload (CHAMP) RO satellite and FORMOSAT-3/COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate) RO constellation together have provided about ten years of high quality global coverage RO atmospheric profiles. This technique is best used for meteorological studies in the difficult-toaccess areas such as deserts and oceans. To better understand and use RO data, effective quality assessment using independent radiosonde data and its associated collocation criteria used in tempo-spatial domain are important. This study compares GPS RO retrieved temperature profiles from both CHAMP (between May 2001 and October 2008) and FORMOSAT-3/COSMIC (between July 2006 and December 2009) with radiosonde data from 38 Australian radiosonde stations. The overall results show a good agreement between the two data sets. Different collocation criteria within 3 h and 300 km between the profile pairs have been applied and the impact of these different collocation criteria on the evaluation results is found statistically insignificantly. The CHAMP and FORMOSAT-3/COSMIC temperature profiles have been evaluated at 16 different pressure levels and the differences between GPS RO and radiosonde at different levels of the atmosphere have been studied. The result shows that the mean temperature difference between radiosonde and CHAMP is 0.39C (with a standard deviation of 1.20 C) and the one Correspondence to: E. Fu (f.fu@bom.gov.au) between radiosonde and FORMOSAT-3/COSMIC is 0.37 C (with a standard deviation of 1.24 C). Different collocation criteria have been applied and insignificant differences were identified amongst the results.
Properties of the narrow line Seyfert 1 galaxies revisited

There is growing evidence to suggest that the black hole mass has been previously underestimated with the H$\beta$ line width for certain active galactic nuclei (AGN). With the assumption of the flatter rather than isotropic velocity distribution of gases in the broad-line region of AGN, we investigated the properties of narrow line Seyfert 1 (NLS1) galaxies, like the black hole mass and the Eddington ratio, and compared with broad line Seyfert 1 (BLS1) galaxies. Since gamma-rays detected in a few NLS1s which favor a smaller viewing angle in NLS1s than BLS1s, with the projection effect we estimated the relative black hole mass and Eddington ratio for NLS1s and BLS1s. The result implies that the NLS1s and BLS1s have similar black hole masses and Eddington ratios, peaked at a larger black hole mass and lower Eddington ratio for the NLS1s than thought before. Furthermore, with applying the correction factor 6 of average black hole mass as derived from the modelling of both optical and UV data in radio-loud NLS1s by Calderone et al., to the Xu et al. sample, we find that the NLS1s and BLS1s also show similar black hole masses and Eddington ratios, peaked at $2.0\times10^{7}M_{\odot}$ and 0.12 (Eddington ratio) for the NLS1s. The $M_{BH}-\sigma$ relation due to the enhanced black hole masses of NLS1s is discussed. In addition, there seems to show a linear correlation between jet power and disk luminosity for the flat spectrum radio-loud NLS1 sample, which implies an accretion dominated rather than black hole spin dominated jet.
Six similar sequential ruptures of the San Andreas fault, Carrizo Plain, California

We document the precise sizes, but not the dates, of the six latest offsets across the San Andreas fault at Wallace Creek, California. Three and perhaps four of these, including the latest in 1857, show dextral offset of 7.5–8 m. The third and fourth offsets, however, are just 1.4 and 5.2 m. The predominance of similar offsets for the latest six events suggests that the fundamental properties of the fault system that control slip size do not vary greatly from event to event. The large offsets imply that ruptures involving this site are typically more than 200 km long.
How Brief Motivational Interventions Impact Math Beliefs in Undergraduate University Students

Despite best efforts, students in U.S. schools still underperform in mathematics compared to many other developed countries, and the achievement gap persists. Teachers play a most important role in student success, yet the knowledge about adult beliefs (and how they can be changed) concerning one’s ability to learn math, the value one has for math, and one’s understanding about how math anxiety derails learning still falls short in informing efforts to best train/support pre-service or in-service teachers. A group of undergraduate university students (N=123) participated in a fully online intervention measuring each of the components in the Expectancy-Value-Cost (EVC) motivational model (Barron & Hulleman, 2015; Eccles & Wigfield, 2002; Wigfield & Eccles, 2000) as it related to their beliefs about mathematics, then completed a three-part intervention (based on Blackwell, Trzesniewski, & Dweck, 2007; Gaspard et al., 2015; and Ramirez & Beilock, 2011), followed by post-measurements of each of the components of EVC. Significant results were obtained for each component of EVC, implying short interventions can effect positive changes in beliefs for adults.
’New Zealand is no more’: Botany and mobility in the career of Leonard Cockayne

An emerging ‘new mobilities paradigm’ in the social sciences has begun to focus critical attention on the meaningfulness of mobility rather than the geometries of movement (Cresswell, 2006). Work framed by this emerging concern has been diverse in its interest in the various means and spaces of mobility. However, as Creswell (2010) has recently argued such work has tended to render mobility as a singular thing rather than an activity constituted through a multiplicity of facets. This paper draws on Creswell’s notion of multiplicity to explore the entangled mobilities of botanical practice in early twentieth century New Zealand as seen through the career of Leonard Cockayne. In doing this the paper argues that recognising the multiple dimensions of mobility in Cockayne’s botanical work offers a ways of helping develop our understanding of the ‘lives told’ of early twentieth scientific practice, and of placing one of those lives within its broader and historical contexts. A process, described by Shapin (2010) as part of the ongoing and necessary effort to understand science as a situated, embodied and very human set of practices.
Marriage Partner Selection by Heterosexual Couples Living with HIV from Rural Southern Malawi

This paper explores marriage partner selection in couples living with HIV using a qualitative research method. The study was conducted in Chikwawa and Chiradzulu districts in Southern Malawi which follow patrilineal and matrilineal marriage traditions, respectively. Data was collected from 20 informants using in-depth interviews from July– December 2010. Four out of 10 matrilineal couples and six out of 10 patrilineal couples established their new marriages when they were HIV-positive. They chose a marriage partner living with HIV because they felt that they would understand each other well and that it was easy to follow the guidelines for HIV positive living thereby negotiating the threat of social stigma from the communities. The results show that, HIV status is important in the decisions that the couples living with HIV make in terms of selecting marriage partners. However, once the new marriage relationships are established based on same HIV positive status, the HIV positive status no longer deters them from having unprotected sexual relationships as evidenced from the children that some of the couples were bearing. The couples indulged in unprotected sex despite being aware that unprotected sex increases the risks of mother to child transmission of HIV and also increases HIV viral load in their bodies. This paper contributes to the literature on living with HIV by focusing on marriage partner selection. Specifically, the findings increase our understanding of how in the pursuit of a normal life people living with HIV decisions to get married, and in the course select the marriage partners that are also living with HIV. We argue that the issue of same status marriage should be dealt with in health programmes in order to limit the risk of new forms of infection. Health care workers and peergroup leaders must be trained on the dangers of HIV super-infection and reproductive decisions, rights, ethics for couples living with HIV. Further studies are needed in Malawi to better inform policy in the formulation of evidence based prevention strategies for couples living with HIV which, in the long run, would address issues of maternal and child mortality from HIV and AIDS.
