description: The hydro-distilled volatile constituents from the stem with leaf and flower of Neanotis lancifolia (Hook.f.) W.H.Lewis (Rubiaceae) were investigated for the first time by using gas chromatography equipped with a flame ionization detector (GC–FID) and gas chromatography coupled with mass spectrometry (GC–MS). Forty-two and twelve compounds were identified from the stem with leaf and flower parts oils, respectively, representing 98.5% and 97.1% of the total oil constituents, respectively. The major constituents were identified as linalool (35.9% stem with leaf; 23.3% flower) and borneol (15.0% stem with leaf; 29.2% flower). The volatile oils of both parts of the plant N. lancifolia were found to be rich in oxygenated monoterpene type of constituents.

description: The structural changes that occurred in the milk market in Rio Grande do Sul, Brazil, during the decade of 2000 generated distinct market structures of factors for production chains in the different regions of the state. In some regions, there is high rivalry between companies for dairy acquisition, while in others, monopsony situations coexist, with no competition. Acknowledging that the informal institutional environment conditions transitional relations between agents in different agribusiness chains, we highlight the power these actor can exert under different market situations, factor which interferes on transition costs. The objective of the present study was to identify, describe and analyze the different raw material market structures of the dairy productive chain from RS and its influence over agent conduct and production chain governance. The objective of the study centered on demonstrating how power relations are established and their influence over these different contexts. In order to conduct this research, we identified and studied four revealing and representative cases from RS: two monopsony cases and two competition oligopsony cases. The methodology of the present qualitative research was comprised of documental research, interviews with farmers, processing company representatives, as well as with key informants. The results showed that the governance structure is dependent on the relative power of the agents. Market structure implies over active specificity, which influences agent interdependence, interfering on the relative power of the same, affecting governance structure.

description: Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography (GC-FID) was explored to determine the fingerprinting characteristic of Zingiber zerumbet L. volatiles to differentiate between different ginger species. The effect of different fibers [polydimethylsiloxane (PDMS, 7 μm), polyacrylate (PA, 85 μm)], different temperature and time on the HS-SPME-GC was investigated by using response surface methodology coupled with full factorial experimental design. The area percentage of the major sesquiterpenes (Zerumbone and α-humulene) were 56.3 ± 4.7% and 47.5 ± 27.2% with PA fiber, respectively at optimum condition of 70 °C and 30 min. Validation of the developed HS-SPME-GC method with limits of detection and quantification for zerumbone was 0.09 and 0.28 μg/g, respectively, demonstrating the suitable sensitivity of HS-SPME-GC method for the quantification of sesquiterpenes. Therefore, the simplicity of HS-SPME-GC makes it a convenient tool for qualitative and quantitative comparison of different ginger species targeting at the marker sesquiterpene molecule, zerumbone.

description: We discuss the possibility of phase-conjugation of an atomic Fermi field via nonlinear wave mixing in an ultracold gas. It is shown that for a beam of fermions incident on an atomic phase-conjugate mirror, a time reversed backward propagating fermionic beam is generated similar to the case in nonlinear optics. By adopting an operational definition of the phase, we show that it is possible to infer the presence of the phase-conjugate field by the loss of the interference pattern in an atomic interferometer.

description: We propose an idea that the observed CP violation in neutrino oscillation is originated from the phase in right-handed neutrino mixing by seesaw mechanism. We add small breaking terms $M_{ij}N_{R_i}N_{R_j} $ in model based on $A_4$ symmetry to generate non-diagonal right-handed neutrino mixing, which will give a small correction to TBM mixing via seesaw mechanism with nonzero reactor angle and CP violating phase. We estimate the CP violating phase by investigating the process of leptogenesis due to the decay of right-handed neutrino.

description: The purpose of this study was to analyze the economic feasibility of chicken farming under integration contracts. Multiple case studies were used to determine the economic situation of the activity performed by rural producers in the States of Minas Gerais and São Paulo. Data referring to zootechnical indicators, costs and incomes were collected for 18 months in every production cycle, in six farms located in Prados, State of Minas Gerais, and two located in Pratânia, State of São Paulo. Economic analyses were carried out based on the average of seven production cycles for each farm, totaling 56 batches. According to results, among eight producers analyzed in this study, the best economic result was not obtained for who showed the greatest production efficiency index, lesser production cost or greater total income. The economic success of this producer was due to the intricate balance between the chicken production performance, production costs, and incomes. In addition, the chicken farming was found to be highly dependent of ancillary incomes to the production process, by means of selling of poultry litter, without which the activity would be unfeasible in medium and long terms for the majority of chicken producers.

description: Aims: This paper has two main objectives: (1) To determine the intrinsic properties of 16 faint and mostly unstudied open clusters in the poorly known sector of the Galaxy at 270$^\circ-$300$^\circ$, to probe the Milky Way structure in future investigations. (2) To address previously reported systematics in Gaia DR2 parallaxes by comparing the cluster distances derived from photometry with those derived from parallaxes. Methods: Deep UBVI photometry of 16 open clusters was carried out. Observations were reduced and analyzed in an automaticway using the ASteCA package to get individual distances, reddening, masses, ages and metallicities. Photometric distances were compared to those obtained from a Bayesian analysis of Gaia DR2 parallaxes. Results: Ten out of the 16 clusters are true or highly probable open clusters. Two of them are quite young and follow the trace of the Carina Arm and the already detected warp. The rest of the clusters are placed in the interarm zone between the Perseus and Carina Arms as expected for older objects. We found that the cluster van den Berg-Hagen 85 is 7.5$\times$10$^9$ yrs old becoming then one of the oldest open cluster detected in our Galaxy so far. The relationship of these ten clusters with the Galaxy structure in the solar neighborhood is discussed. The comparison of distances from photometry and parallaxes data, in turn, reveals a variable level of disagreement. Conclusions: Various zero point corrections for Gaia DR2 parallax data recently reported were considered for a comparison between photometric and parallax based distances. The results tend to improve with some of these corrections. Photometric distance analysis suggest an average correction of $\sim$+0.026 mas (to be added to the parallaxes). The correction may have a more intricate distance dependency, but addressing that level of detail will require a larger cluster sample.

description: We describe, in this study, the strategic positioning of a cooperative of milk producers located in the State of Rio Grande do Sul, for the period from 2005 to 2013. We describe strategies used by the cooperative, highlighting three important strategic periods, and the competitive strategies designed for each period. It is an applied and descriptive case study performed in the qualitative perspective (TRIVIÑOS, 1987). Regarding procedures used to collect and analyze data, we used the direct research approach as outlined in Mintzberg (1979). Results show that the cooperative focused its competitive strategy in two basic aspects: in the rural producer, establishing differentials in terms of qualified technical assistance, and the partnership between the cooperative and its members; and in the final consumer, in order to offer a product with quality and originality, with a competitive advantage.

description: Student absences are a potentially important, yet understudied, input in the educational process. Using longitudinal data from a nationally-representative survey and rich administrative records from North Carolina, we investigate the relationship between student absences and academic performance. Generally, student absences are associated with modest but statistically significant decreases in academic achievement. The harmful effects of absences are approximately linear, and are two to three times larger among fourth and fifth graders in North Carolina than among kindergarten and first-grade students in the nationally representative Early Childhood Longitudinal Study. In both datasets, absences similarly reduce achievement in urban, rural, and suburban schools. In North Carolina, the harm associated with student absences is greater among both low-income students and English language learners, particularly for reading achievement. Also, in North Carolina, unexcused absences are twice as harmful as excused absences. Policy implications and directions for future research are discussed.
Stochastic unraveling of Redfield master equations and its application to electron transfer problems

description: A method for stochastic unraveling of general time-local quantum master equations (QMEs) is proposed. The present kind of jump algorithm allows a numerically efficient treatment of QMEs which are not in Lindblad form, i.e. are not positive semidefinite by definition. The unraveling can be achieved by allowing for trajectories with negative weights. Such a property is necessary, e.g. to unravel the Redfield QME and to treat various related problems with high numerical efficiency. The method is successfully tested on the damped harmonic oscillator and on electron transfer models including one and two reaction coordinates. The obtained results are compared to those from a direct propagation of the reduced density matrix (RDM) as well as from the standard quantum jump method. Comparison of the numerical efficiency is performed considering both the population dynamics and the RDM in the Wigner phase space representation.

description: The associative model for sugarcane growers is based on their association per region. In the Center-South Region of Brazil, for example, there are 31 associations with about 18 thousand growers, and locally represented by the Sugarcane Growers Organization of the Center-South Region of Brazil (ORPLANA). However, recent sector changes, especially in terms of deregulation, crisis and consolidation, have led some associations to the weakening. On the other side, some associations have grown in the last years. This variability shows the need for studying the existing differences among associations in terms of the role they perform, as well as an investigation of which organizational profile ismore related to their growth and development; configuring a clear representation efficiency. This research was performed within the view of transaction cost economics, with contribution of collective action theory. Questionnaires were applied to 23 managers or presidents of associations. In addition, the statistical grouping based method was used. According to results, three distinct groups of association were identified, which were named as “Techniques”, “Politics”, and “Spokespeople”. The first group was found to be more efficient and prosperous in growth than others. Besides, it has striking features on its profile, such as a diverse scope of activities, high size, developed structure, involvement with cooperatives, strong performance in services, and great number of factories.

description: We report on the structural and transport properties of the smallest dislocation loop in graphene, known as a flower defect. First, by means of advanced experimental imaging techniques, we deduce how flower defects are formed during recrystallization of chemical vapor deposited graphene. We propose that the flower defects arise from a bulge type mechanism in which the flower domains are the grains left over by dynamic recrystallisation. Next, in order to evaluate the use of such defects as possible building blocks for all-graphene electronics, we combine multiscale modeling tools to investigate the structure and the electron and phonon transport properties of large monolayer graphene samples with a random distribution of flower defects. For large enough flower densities, we find that electron transport is strongly suppressed while, surprisingly, hole transport remains almost unaffected. These results suggest possible applications of flowered graphene for electron energy filtering. For the same defect densities, phonon transport is reduced by orders of magnitude as elastic scattering by defects becomes dominant. Heat transport by flexural phonons, key in graphene, is largely suppressed even for very low concentrations.

description: Americans are changing the way they eat and the foods they buy. New lifestyles, shifting demographics, and growing concerns about nutrition and health contribute to these changes. In response to American consumers, the food system may be shifting from volume production for general consumer markets to marketing and production for specialized markets. These changes have not influenced all parts of the food system equally, according to ERS researchers who examined how changes in food demand affect the food system's output in different sectors for 1972-92. Within the food system, real output grew during 1972-92 for the processed food sectors and eating and drinking places (table 1). The poultry and egg processing sector showed the largest percentage growth, 269 percent (from $6,472 million in 1972 to $23,865 million in 1992), followed by confectionery, bakery, and macaroni, 85 percent (from $23,252 million to $43,118 million). Output for the meat packing sector grew the least, 11 percent (from $56,340 million to $62,440 million) over the period and refined sugar sector output declined 26 percent (from $8,010 million in 1972 to $5,909 million in 1992). Overall, the total real output of processed food sectors rose 40 percent (from $243 billion in 1972 to $342 billion). The nonfood processing sectors in the food system grew strongly. Output in transportation rose 82 percent from $182 billion in 1972 to $332 billion in 1992. Output for wholesale and retail trade grew 86 percent, from $496 billion to $926 billion. Output for the eating and drinking sector grew 83 percent, from $114 billion to $210 billion.

description: We report on a recent event in which, after more than a decade of slowly fading, the visual brightness of the massive young binary Z CMa suddenly started to rise by about 1 magnitude in December 1999, followed by a rapid decline to its previous brightness over the next six months. This behaviour is similar to that exhibited by this system around its eruption in February 1987. A comparison of the intrinsic luminosities of the system with recent evolutionary calculations shows that Z CMa may consist of a 16 M_sun B0 IIIe primary star and a ~ 3 M_sun FUOr secondary with a common age of ~ 3 x 10^5 yr. We also compare new high-resolution spectra obtained in Jan. and Feb. 2000, during the recent rise in brightness, with archive data from 1991 and 1996. The spectra are rich in emission lines, which originate from the envelope of the early B-type primary star. The strength of these emission lines increased strongly with the brightness of Z CMa. We interpret the collected spectral data in terms of an accretion disc with atmosphere around the Herbig B0e component of Z CMa, which has expanded during the outbursts of 1987 and 2000. A high resolution profile of the 6300 A [O I] emission line, obtained by us in March 2002 shows an increase in flux and a prominent blue shoulder to the feature extending to ~ -700 km/s, which was much fainter in the pre-outburst spectra. We propose that this change in profile is a result of a strong change in the collimation of a jet, as a result of the outburst at the start of this century.

title: Challenging behaviour and inclusion in a secondary school: Perceptions, policies and practices
Creators: name: Fripps, Linda Emily
Publisher: name: The Open University
Year: 2011

description: It has been widely reported in research and by the media that pupils' challenging behaviour causes concern amongst teachers, parents and politicians. Theories abound attributing indiscipline to factors related to the child, the family and, to a lesser degree, the school. This study investigates the experiences and perceptions of pupils and staff regarding challenging behaviour and inclusion in a mainstream secondary school. The research seeks the views of pupils considered challenging by school authorities and also those of their teachers. It also elicits the opinions of pupils who are generally considered to be well-behaved and those of support staff, as their experience of behaviour in mainstream schools appears to be understudied within the existing literature. The research took place at an all-ability Roman Catholic boys' school in a selective London Borough. The school has adopted measures to address challenging behaviour, including the use of punitive spaces such as the detention room and an inclusion unit. Within these spaces discipline is exercised and the implicit aim is to produce 'docile bodies' (Foucault, 1977, p.138). The study incorporates methods designed to facilitate students' involvement as participants and co-researchers. The research findings stress the importance of relationships with peers, parents and teachers in children's behaviour. The notion of blame is also advanced. Each group blames others for indiscipline and generally absolves itself of responsibility for it. Children whose behaviour is seen as challenging are 'othered' by staff and students alike, who place limits on inclusion and advocate an exclusionary approach to addressing indiscipline. In describing developments arising from the research, the study advocates listening to children and highlights the importance of collaborative working and consistency in developing and implementing whole school policy and inclusive practice relating to behaviour in school.

description: Current interest in spintronics is largely motivated by a belief that spin based devices (e.g. spin field effect transistors) will be faster and consume less power than their electronic counterparts. Here we show that this is generally untrue. Unless materials with extremely strong spin orbit interaction can be developed, the spintronic devices will not measure up to their electronic cousins. We also show that some recently proposed modifications of the original spin field effect transistor concept of Datta and Das [Appl. Phys. Lett., Vol. 56, 665 (1990)] actually lead to worse performance than the original construct.

description: IBM Research Castor, a cloud-native system for managing and deploying large numbers of AI time-series models in IoT applications, is described. Modelling code templates, in Python and R, following a typical machine-learning workflow are supported. A knowledge-based approach to managing model and time-series data allows the use of general semantic concepts for expressing feature engineering tasks. Model templates can be programmatically deployed against specific instances of semantic concepts, thus supporting model reuse and automated replication as the IoT application grows. Deployed models are automatically executed in parallel leveraging a serverless cloud computing framework. The complete history of trained model versions and rolling-horizon predictions is persisted, thus enabling full model lineage and traceability. Results from deployments in real-world smart-grid live forecasting applications are reported. Scalability of executing up to tens of thousands of AI modelling tasks is also evaluated.

description: A strong economy combined with stricter food stamp eligibility rules in fiscal year 1998 led to fewer people receiving Federal food assistance and a resulting decrease in food-assistance program costs. Federal Government expenditures on these programs totaled $33.6 billion in fiscal year 1998, a fall of 6 percent from the previous year, making this the second consecutive year in which total expenditures declined. Prior to fiscal year 1997, annual food-assistance program expenditures had increased for 14 consecutive years (fig. 1), which are measured from October through September rather than by calendar year. (The data cited in this article are based in part on preliminary data submitted by various reporting agencies as of December 1998 and are subject to change as reporting agencies finalize data.) The U.S. Department of Agriculture's (USDA) Food and Nutrition Service (FNS) administers the wide assortment of food-assistance programs that differ by expenditure level, the population groups they serve, and the types of benefits provided (see box on domestic foodassistance programs). Most of the decrease in total food-assistance expenditures in fiscal year 1998 was attributed to the Food Stamp Program; other programs expanded. Individual programs, when grouped into four broad categories-Food Stamp-Related, Child Nutrition, Supplemental Food, and Food Donation-reveal general patterns and trends.

description: We study the world data on elastic electron-proton scattering in order to determine the proton charge rms-radius. After accounting for the Coulomb distortion and using a parameterization that allows to deal properly with the higher moments we find a radius of 0.895+-0.018 fm, which is significantly larger than the radii used in the past.

A Bayesian Account of Quantum Histories

Subjects: subject: Quantum Physics (quant-ph)

description: We investigate whether quantum history theories can be consistent with Bayesian reasoning and whether such an analysis helps clarify the interpretation of such theories. First, we summarise and extend recent work categorising two different approaches to formalising multi-time measurements in quantum theory. The standard approach consists of describing an ordered series of measurements in terms of history propositions with non-additive `probabilities'. The non-standard approach consists of defining multi-time measurements to consist of sets of exclusive and exhaustive history propositions and recovering the single-time exclusivity of results when discussing single-time history propositions. We analyse whether such history propositions can be consistent with Bayes' rule. We show that certain class of histories are given a natural Bayesian interpretation, namely the linearly positive histories originally introduced by Goldstein and Page. Thus we argue that this gives a certain amount of interpretational clarity to the non-standard approach. We also attempt a justification of our analysis using Cox's axioms of probability theory.

Who is the average individual investor? Numerical skills and implications for accounting research

description: Behavioral research in financial accounting often aims to address issues relevant to individual, nonprofessional investors, citing the importance of individual investors to capital markets or regulators’ concerns for the “average” investor. Analyzing national samples of financial capability skills in the United States along with a relatively large sample of participants recruited from Amazon’s Mechanical Turk platform (MTurk; n>2,000), this research first examines investors’ demographic characteristics and numerical skills relative to non-investors, thus contributing to our understanding of the “average” individual investor’s skills and perceptions and to our understanding of the range of skills and perceptions in the broader individual investor population. A sample of three extant accounting research experiments are then replicated with the MTurk participant pool; however, these replicated results tend to be driven by participants with investment experience and higher numerical skills. These findings suggest that limiting the pool of participants in the original research increases the power of the statistical tests, but doing so may overstate the generalizability of the findings to less sophisticated investor populations. This research emphasizes the need for careful consideration of the research motivation and the potential match between the applied theory and the population of interest in empirical research.
