description: Previous research on pediatric cancer populations has reported considerable variability in psychological adjustment. The present study was designed to examine different models of predicting adjustment in adolescent cancer survivors. In particular, this study sought to clarify the role of child factors (i.e., personality, appraisal, and coping) in predicting self-esteem and psychological distress while controlling for more established predictors, such as disease, family, and support variables. Additive and moderated mediational models of prediction were tested in a mail-out questionnaire study with a sample of 65 adolescent survivor-parent dyads. Support was obtained for an additive model in which optimism, peer support, and age at diagnosis predicted significant variance in self-esteem while controlling other factors. Support was also obtained for an additive model in which neuroticism and a disengagement coping strategy, cognitive avoidance, predicted significant variance above and beyond family, support, and disease covariates. The hypothesized moderated mediational models were not supported; however, support for a simpler model, in which cognitive avoidance partially mediated the relationship between neuroticism and psychological distress was obtained. Results of this study underscore the importance of considering child factors, which have largely been neglected in previous research, in predicting adjustment in pediatric cancer survivors. In particular, the results of the present study help to paint a picture of what a more resilient adolescent cancer survivor might look like. This adolescent would be lower in neuroticism, higher in optimism, and would engage in less cognitive avoidance and possibly less protective buffering, as trying to keep his or her distress from others may actually be detrimental to the adolescent. Finally, he or she would have a close and supportive peer network and a higher functioning, less distressed family. Research and clinical implications o f these findings are discussed.

description: Brain oscillations are crucial for several cognitive functions, such as memory, attention, perception, and communication between brain regions. In particular, visual familiarity is known to induce oscillations in the theta frequency band (4-8 Hz). Today, most machine learning models lack this biologically inspired component. In the first aim of this study, we build a deep learning model that exhibits oscillations in the theta band using predictive coding theory. Predictive coding theory suggests that higher-order brain regions predict the activity of lower-order brain regions. The prediction errors are then propagated up the hierarchy and the predictions are updated. We were able to replicate the neural activities seen in a mouse training paradigm and observed that units of the neural network also exhibit oscillations in the theta band for a familiar stimulus. This offers the potential to bridge the gap between artificial neural networks and biological systems to build more biologically plausible neural networks. In the second objective of this study, we investigate the learning impairment of FragileX (FX) mice compared to Wild-Type (WT) mice when trained to discriminate Go and No-Go visual stimuli. Using recorded neural data, we build a classifier to perform stimuli and genotype classification. Both FX and WT mice achieved significantly higher accuracies in the theta oscillatory activity window compared to spontaneous activity in the V1 region. This suggests that the theta oscillations store essential information learned from visual discrimination. However, we observe that FX mice require more neuronal units to achieve performance similar to that of WT mice. In the hippocampus, the overall accuracy was lower for the classification of stimuli, indicating a more complex nature of information processing in the hippocampus. In addition, high classification accuracies for genotype decoding indicate that the neural responses to stimuli in V1 region are influenced by genetic variations. These differences are discernible even in individual trials when averaged across a few hundred neurons.Classification using neural activities from Go trials yielded a higher accuracy than No-Go trials suggesting that these differences could be task-dependent and enhanced during certain tasks. We also observed that these variations are more notable during the theta oscillatory activity window demonstrating that genetic factors substantially influence memory encoding via theta oscillations.

description: Economic reform in China helped transform the structure and volume of agricultural production and resulted in significant changes in efficiency and productivity. This paper measures agricultural technical efficiency (TE) and total factor productivity (TFP) in China by allowing producers operating under their own technologies. A metafrontier function approach is applied using a panel data set on 28 provinces during 1991-2005. The provinces are categorized into advanced- technology and low-technology provinces. Based on the metafrontier estimation, TFP growth is decomposed into TE change (TEC), technical change (TC) and scale efficiency change (SEC). This information is useful for policy makers to design suitable policies in enhancing agricultural TE and TFP growth in China. Our major findings indicate that TC was mostly attributed to Chinese agricultural TFP growth throughout the period of study. SEC and TEC exhibited negative effects to TFP growth for the advance- and low-technology provinces, respectively. Most of the advanced-technology provinces exhibited higher TE than the low-technology provinces. The comparatively low TE scores in the low-technology provinces imply that the low-technology provinces were operating far from the metafrontier. The fluctuation of TE measured with respect to the metafrontier function indicates it is possible that Chinese agricultural TFP growth can be improved through the improvement of TE. The results also show that labor and fertilizer still make important contributions to output, and thus improving the quality of farmers and applying modern physical inputs is also crucial to TFP growth.

description: We outline the confluence of three novel theoretical fields in our modeling of Gamma-Ray Bursts (GRBs): 1) the ultrarelativistic regime of a shock front expanding with a Lorentz gamma factor $\sim 300$; 2) the quantum vacuum polarization process leading to an electron-positron plasma originating the shock front; and 3) the general relativistic process of energy extraction from a black hole originating the vacuum polarization process. There are two different classes of GRBs: the long GRBs and the short GRBs. We here address the issue of the long GRBs. [...] We are specially interested, in this report, to a subclass of long GRBs which appear to be accompanied by a supernova explosion. We are considering two specific examples: GRB980425/SN1998bw and GRB030329/SN2003dh [...].

description: The agri-food sector was given remarkable amounts of funding by all German federal states in the framework of the Measure g ‘Improving Processing and Marketing of Agricultural Products’ within the rural development programs. Based on literature and data we obtained by evaluating this program we identified some indicators representative for illustration of sustainable development, Apart from project data we used the official statistics and the method of case studies. Via selected indicators we received some signs of sustainable development in enterprises of the agri-food industry that also influence the development of rural area. Some statements are restricted because net effects can not be determined. The need for subsidies is discussed as well as possibilities and limits of case studies.

description: We initiate the study of the asymptotic behavior of small solutions to one-dimensional Klein-Gordon equations with variable coefficient quadratic nonlinearities. The main discovery in this work is a striking resonant interaction between specific spatial frequencies of the variable coefficient and the temporal oscillations of the solutions. In the resonant case a novel type of modified scattering behavior occurs that exhibits a logarithmic slow-down of the decay rate along certain rays. In the non-resonant case we introduce a new variable coefficient quadratic normal form and establish sharp decay estimates and asymptotics in the presence of a critically dispersing constant coefficient cubic nonlinearity. The Klein-Gordon models considered in this paper are motivated by the study of the asymptotic stability of kink solutions to classical nonlinear scalar field equations on the real line.

description: Firstly, the paper establishes a brand-extension size model and adopts the marginal analysis to analyze the optimal solution of it. Secondly, research the brand-extension condition of G brand by questionnaire survey. There are 240 questionnaires handed out, with 211 withdrawing and 187 valid, by doing this to test the influencing degree of each factor in brand-extension size model; At the same time, use analytic hierarchy process to analyze the size of brand extension and principal component analysis to find out the main factors that influence brand extension of G brand. Finally, the paper makes an empirical analysis on brand extension size model based on ecological characteristics, the results show that the order of the total information reflected by each principal component which obtained from the principal component analysis is somewhat different from that of analytic hierarchy process; With the continuous improvement of living standards, the consumers pay more attentions to the convenience of shopping and comfort of shopping environment day by day. Therefore, the brand enterprises must strengthen environmental construction of brand group and satisfy the growing material and cultural demand of consumers. Success rate of brand extension to a great extent has a close relationship with the products and product channel, compared to foreign brand, consumers are relatively weak in brand communication and association of the products.

description: Firstly, status of grain production in Henan Province is introduced. The rapid development of grain production has brought adequate food and clothing for Henan Province, has supported the development of industrial and agricultural production, has maintained the overall stability of the whole society, and has made great contribution to the national food security. Secondly, considering the small sample of research object, the uncertain poor information and the few restrictions on data distribution, the gray forecast is usually conducted by using time series data based on GM（1，1） Model. In order to ensure the high accuracy and the application in practical prediction, residual test is used. Thirdly, according to the grain productive data in Henan Province in the years 1996-2008, Gray Prediction Model of grain production in Henan Province is established. Simulation and prediction results are obtained by the calculation of Gray System Modeling Software, indicating that grain production of Henan Province still shows a steady rise in future, and reflecting the change law of grain production. Finally, predicted target is divided into three stages according to the planning. And analysis shows that the planning target is practical and feasible.

description: We consider the first-passage problem for $N$ identical independent particles that are initially released uniformly in a finite domain $Ω$ and then diffuse toward a reactive area $Γ$, which can be part of the outer boundary of $Ω$ or a reaction centre in the interior of $Ω$. For both cases of perfect and partial reactions, we obtain the explicit formulas for the first two moments of the fastest first-passage time (fFPT), i.e., the time when the first out of the $N$ particles reacts with $Γ$. Moreover, we investigate the full probability density of the fFPT. We discuss a significant role of the initial condition in the scaling of the average fastest first-passage time with the particle number $N$, namely, a much stronger dependence ($1/N$ and $1/N^2$ for partially and perfectly reactive targets, respectively), in contrast to the well known inverse-logarithmic behaviour found when all particles are released from the same fixed point. We combine analytic solutions with scaling arguments and stochastic simulations to rationalise our results, which open new perspectives for studying the relevance of multiple searchers in various situations of molecular reactions, in particular, in living cells.

description: According to the urban and rural income levels and the national poverty line, peasant households are classified into poor households, middle-income households and wealthy households. Based on the investigation data of 259 peasant households in three villages of Hebei Province, the features of family structure, economy, ideology and communication of peasant households with different income levels in current status are analyzed. The result shows that there are great differences in family structure, ideology, economy and communication of peasant households with different income levels. The low-income households are featured by unreasonable family structure, heavy burden, conservative behavior and blocking information. While the middle and high income households are good at communicating and willing to take risk and armed with high skills. Based on this, relevant suggestions are put forward to promote the development of peasant households, such as optimizing family structure, cultivating the capacity of the core numbers of the family, guiding households to choose a suitable development path, encouraging farmers to work outside, ensuring the legitimate rights and interests of migrant workers, flourishing rural culture, and setting up good platform for the communication of households.

description: In order to investigate mass transport and planet formation by gravitational instabilities (GIs), we have extended our 3-D hydrodynamic simulations of protoplanetary disks from a previous paper. Our goal is to determine the asymptotic behavior of GIs and how it is affected by different constant cooling times. Initially, Rdisk = 40 AU, Mdisk = 0.07 Mo, M* = 0.5 Mo, and Qmin = 1.8. Sustained cooling, with tcool = 2 orps (outer rotation periods, 1 orp ~ 250 yrs), drives the disk to instability in ~ 4 orps. This calculation is followed for 23.5 orps. After 12 orps, the disk settles into a quasi-steady state with sustained nonlinear instabilities, an average Q = 1.44 over the outer disk, a well-defined power-law Sigma(r), and a roughly steady Mdot ~ 5(-7) Mo/yr. The transport is driven by global low-order spiral modes. We restart the calculation at 11.2 orps with tcool = 1 and 1/4 orp. The latter case is also run at high azimuthal resolution. We find that shorter cooling times lead to increased Mdots, denser and thinner spiral structures, and more violent dynamic behavior. The asymptotic total internal energy and the azimuthally averaged Q(r) are insensitive to tcool. Fragmentation occurs only in the high-resolution tcool = 1/4 orp case; however, none of the fragments survive for even a quarter of an orbit. Ring-like density enhancements appear and grow near the boundary between GI active and inactive regions. We discuss the possible implications of these rings for gas giant planet formation.

description: Based on the clear introduction of the connotation of marginalization, the index of diagnosing the marginalization degree is put forward. According to the 685 copies of questionnaires on peasant households in Tongcheng County of Hubei Province and the statistical data of local government, marginalization of arable land and its correlation with rural labor migration in Tongcheng County are studied by using aggregative indicator method, clustering analysis method and correlation analysis method. Result shows that marginalization of arable land has happened two times in Tongcheng County since 1985. Dry land has severer marginalization degree than paddy field. There is significant correlation between marginalization degree of arable land and rural labor migration; and the correlation between marginalization degree and rural labor migration in paddy field is greater than that in dry land. Marginalization of arable land will advance the rural labor migration, while in response to the poor current circulation of lands; the rural labor migration will further deepen the marginalization degree. Marginalization of arable land is one of the important factors affecting the labor migration in rural areas.
Development in children’s conceptions of mental illness : relations to social perspective coordination and emotional understanding

Publisher: name: University of British Columbia
Year: 2009

description: The present study provided a first step in the integration of our efforts to understand more clearly children's conceptions of mental illness. Gender and age changes in conceptions of mental illness (i.e., recognition of adaptive functioning, estimations of positive prognosis, attributions of causality, and attitudes toward peers with mental illness) were examined in relation to social perspective coordination and emotional understanding to determine whether children's conceptions are associated with concomitant levels of development in these constructs. Further, these social cognitive constructs were explored as potential mechanisms underlying children's conceptions of psychopathology to determine their relative influence in predicting dimensions of mental illness conceptions. To this end, 160 children across grades one, four, and seven were read a series of mental illness vignettes and were administered measures assessing their conceptions of mental illness, perspective taking skills, emotional understanding, and receptive verbal ability. The results generally revealed significant increases across grades in both social perspective coordination and emotional understanding and significant decreases in the positive beliefs of mental illness composite score. Children's attributions of causality for mental illness were also shown to be associated with changes in social perspective coordination and emotional development. Moreover, a generally consistent age-related increase in the use of psychological illness attributions of causality and an age-related decrease in the use of physical/biological explanations across different types of disorders were revealed. Finally, the results demonstrated that all children perceived the conduct-disordered vignette character as the most severe and least likeable character with a poorer long-term prognosis. This finding suggests that regardless of age, participants perceive antisocial behavior as most demonstrative of mental illness in terms of severity, prognosis, and likeability. Theoretical and practical implications of these findings are discussed in terms of the strengths and limitations of the present study and suggestions for future research.

We show that the measurement of the conductance between the two electrodes through the electrolyte provides an accurate and reproducible way to control their separation. We have tested the robustness of the electrodes by applying large voltages across them and by using them to measure the transport properties of Au nano-clusters. Our results show that the technique reliably produces metallic electrodes with a separation that bridges the minimum scale accessible by electron beam lithography with the atomic scale.

Relationship between the development level and the institutional factors affecting the economic performance of cooperative organizations is studied by using factor analysis method. Result shows that there is relatively high consistency between the score of institutional factor and the development level of cooperative organization. Both macroscopic support system and internal benefit distribution system have greater impacts on the Peasant Special Cooperative Organization; the internal supervision factor and the interest factor of core members have insignificant impacts on the economic performance; and the production management factor has little effect on economic performance. Based on this, several suggestions are put forward, including standardizing and reforming the system, improving the countermeasures for economic performance, strengthening the support and policy guidance for Peasant Special Cooperative Organization, improving and standardizing the distribution of benefit system, the security system and monitoring system for core members’ interests, and fully reflecting the interests of core members.

description: The first analysis of the photometric observation in BVR filters of a W UMa type binary system BQ Ari was performed. Light curve analysis was performed using Wilson-Devinney (W-D) code combined with a Monte Carlo (MC) simulation to determine its photometric and geometric elements and their uncertainties. These results show that BQ Ari is a contact binary system with a photometric mass ratio q=0.548\pm0.019, a fillout factor f=24\pm0.8 percent, and an orbital inclination of i=85.09\pm0.45. We used the parallax from Gaia EDR3 for calculating the absolute parameters of the binary system. This study suggested a new linear ephemeris for BQ Ari, combining our new mid-eclipse times and the previous observations, which we analyzed using the Monte Carlo Markov Chain (MCMC) method. We present the first analysis of the system's orbital period behavior by analyzing the O-C diagram using the Genetic Algorithm (GA) and the MCMC approaches in OCFit code. We attempted to explain the analysis of the residuals of linear fit in the O-C diagram with two approaches; "LiTE + Quadratic" and "Magnetic activity + Quadratic". Although we consider the magnetic activity to be probable, the system should be studied further in order to reveal the nature of orbital period variations.

description: While controversy surrounds skewness attributes of typical yield distributions, a better understanding is important for agricultural policy assessment and for crop insurance rate setting. Day (1965) conjectured that crop yield skewness declines with an increase in low levels of nitrogen use, but higher levels have no effect. In a theoretical model based on the law of the minimum (von Liebig) technology, we find conditions under which Day’s conjecture applies. Employing four experimental plot datasets, we investigate the conjecture by introducing (a) a flexible Bayesian extension of the Just-Pope technology to incorporate skewness, and (b) a quantile-based measure of skewness shift. For corn yields, the Bayesian estimation provides strong evidence in favor of negative skewness at commercial nitrogen rates and for Day’s conjecture. There was weaker evidence in favor of positively skewed cotton yield and little evidence in favor of the conjecture. The results are also confirmed by the quantile-based measure.

description: Since 2000, ‘The System of Direct Payment of Subsidies to Farmers in Hilly and Mountainous Areas’ is in operation in Japan. The objective of this paper is to evaluate and survey Japan’s policy for less favoured areas. This system has two characteristics: ‘coverage subsidies for disadvantage’ and ‘subsidies for rural community activation’. Given these characteristics, the subsidy system can be evaluated to have exhibited high effectiveness. I have statistically analyzed the outcomes of this system. But I conclude that it does not have a promising future because subsidies are inadequate for maintaining household finances of farmers.

description: The role of Rural Development Policy is growing nowadays. As an EU member state Bulgaria started implementation of Rural Development Policy. The paper analyse the level of achievement of the Rural Development Programme’s objectives in Bulgaria. The programme started in 2008 and most of the measures are implemented. But effective payments have been done only under eight measures. The vast majority of financed projects are for investments mainly in agriculture (for perennial crops production, buildings, machineries and equipment). In the paper are specified opportunities and challenges of the rural development policy in Bulgaria in order to be consistent with the new rural paradigm.

description: After accession to EU, farmers in the new-member states have to adjust to the EU agricultural policies and market. In Slovenia an analysis is made of the farm development plans and information exchange under quota and CAP. Three research questions were addressed: what information is received and how; how does the farmer prefer to receive information and what kind; how to make decisions to react to the new EU policies concerning farm management and future plans. These questions were linked to the base variables, being the farm and farmers’ characteristics. As tool a questionnaire was distributed to dairy farmers. 1114 questionnaires, 22% of the distributed ones have been returned anonymously, implying that 11% of the dairy farmers’ population is part of the analysis. It appeared that the research sample of farmers used represents the more future oriented farmers. As main factors describing the farm and farmers’ characteristics were found farm size, age and number of other activities than dairy. Results show that nearly all farmers did receive information about some specific aspects of the quota system. Communication channels dealing with this administrative info and also with farm management advice are divers, but frequency of direct contact with advisors may be less than predicted. Results also indicate a very significant demand for info about strategic planning, farm management aspects and EU premium programs, especially about CAP general policies and milk premiums, and a considerable activity in farm planning. About 40% of farmers choose for keeping the farm business the same and 50% intend to develop the farm further.
