description: Entropic force originates in the assumption that there is a horizon for the universe. This horizon gives rise to additional terms in the equations of motion. Using dynamical system calculations, our results show that in the presence of dark energy for certain conditions, the last attractor of this theory will be dark energy epoch, but in the absence of dark energy, entropic force energy portion will have the lead role in the late time universe and is responsible for accelerated expansion of that. Interestingly, assuming both entropic force terms and dark energy to have their share of energy density of the universe, we have found that, in certain conditions entropic force dominated epoch is a stable fixed point while the dark energy epoch is a saddle point.

description: We present emission line mapping of the strongly barred galaxy NGC 1530 obtained from Fabry-Perot interferometry in Halpha, at significantly enhanced angular resolution compared with published studies. The main point of the work is to examine in detail the non-circular components of the velocity field of the gas, presumably induced by the strongly non-axisymmetric gravitational potential of the bar. These reveal quasi-elliptical motions with speeds of order 100 km/s aligned with the bar. It also shows how these flows swing in towards and around the nucleus as they cross a circumnuclear resonance, from the dominant "x1 orbits" outside the resonance to "x2 orbits" within it. Comparing cross-sections of the residual velocity map along and across the bar with the Halpha intensity map indicates a systematic offset between regions of high non-circular velocity and massive star formation. To investigate further we produce velocity gradient maps along and across the bar. These illustrate very nicely the shear compression of the gas, revealed by the location of the dust lanes along loci of maximum velocity gradient perpendicular to the bar. They also show clearly how shear acts to inhibit massive star formation, whereas shocks act to enhance it. Although the inhibiting effect of gas shear flow on star formation has long been predicted, this is the clearest observational illustration so far of the effect. It is also the clearest evidence that dust picks out shock-induced inflow along bars. These observations should be of considerable interest to those modelling massive star formation in general.

description: Entrepreneurship and innovation play a key role in combating problems facing agribusinesses, including the need for water conservation, sustainable packaging, and environmental protection. These issues have led to an increasing demand for college graduates with technical skills and innovative ways of thinking. The objective of our research is to provide insight into character traits that signal entrepreneurial skills. We conducted a survey to examine entrepreneurial interests and perspectives among U.S. agribusiness students. A cluster analysis revealed that entrepreneurial-minded students were more likely to be male, consider themselves risk takers, and have parents directly engaged in production agriculture. Our results emphasize the importance for universities to build students’ experiences through industry partnerships, where students can interact with entrepreneurial mentors and get hands-on knowledge through applied coursework and internships in entrepreneurship. In addition, our study aids industry managers to learn more about future employees and their perceptions of entrepreneurial activities.

description: Thermoelectricity describes phenomena that allow us to convert heat into electricity and vice versa. The practical implications of this conversion are obvious. However, research on thermoelectric effects also leads to a deep understanding of the electronic properties in conductive materials. In this paper, we discuss the most interesting results obtained recently in ultrasmall conductors, where the electronic behavior is purely quantum and classical theories of thermoelectricity are thus to be revised in detail.

On the temperature dependence of 2D "metallic" conductivity in Si inversion layers at intermediate temperatures

description: We show that the recent experimental claim [Pudalov {\it et al}. \prl {\bf 91}, 126403 (2003) ] of observing ``interaction effects in the conductivity of Si inversion layers at intermediate temperatures'' is incorrect and misleading. In particular, the temperature dependent conductivity $σ$, in contrast to the resistivity (which is what is shown in the paper), does not have a linear temperature regime, rendering the extraction of the slope $dσ/dT$ completely arbitrary. We also show that, at least for higher densities, the standard semiclassical transport theory, which includes realistic disorder effects such as scattering by {\it screened} charged impurity and surface roughness, gives essentially quantitative agreement with the experimental data.

description: We calculate the Landauer conductance through chaotic ballistic devices in the semiclassical limit, to all orders in the inverse number of scattering channels without and with a magnetic field. Families of pairs of entrance-to-exit trajectories contribute, similarly to the pairs of periodic orbits making up the small-time expansion of the spectral form factor of chaotic dynamics. As a clue to the exact result we find that close self-encounters slightly hinder the escape of trajectories into leads.

title: Learner-Centredness and Teacher-Educators in India: A Case Study of a Teacher-Educator at a District Institute of Education and Training
Creators: name: Sarkar, Sumita
Publisher: name: The Open University
Year: 2015

description: Learner-centred education (LCE) has gained firm policy support for school education in India to change from the prevalent teacher-led practice to one in which the learner is actively involved. It has been suggested that this shift calls for new ways of teaching and learning. However, there is little published research on prevalent practices in Indian teacher-educators' classrooms in teacher-training institutes. This small-scale case study seeks to provide insights into the learner-centredness of a teacher-educator in her conception and practice and how a District Institute of Education Training (DIET) in India supports LCE as recommended by the National Curriculum Framework for Teacher Education (2009) and international discourse. The research was ethnographically led with data collected from classroom observations, semi-structured interviews and a group discussion, and analysed thematically. The study was influenced by the theoretical framework provided by the Activity Theory that underlines the importance of interactions between the principal, teacher-educators, students, rules, facilities, systems, processes and environment at the DIET. This research report provides a qualitative overview of the learner-centredness of a teacher-educator in her classroom by using a rubric tool developed for the purpose. The study found that while the teacher-educator's own beliefs and experience influence her to become a learner-centred teacher, the teacher education institute also plays a crucial role in influencing and developing her understanding of LCE in theory and practice. This has implications for the professional development of teacher-educators and systemic changes needed in teacher education institutes adopting LCE to develop learner-centred primary school teachers.

description: Benefits of cooperative organization in agriculture come from price advantages in procurement and marketing, cost reductions and efficiency gains from sharing of productive assets and processes, and improved access to and increased efficiency in using credit, logistics, and information. Efficacy of strategic activities designed to capture these advantages is investigated empirically in a case study of the Tonghui Agricultural Cooperative in Inner Mongolia, an autonomous region of China. Information from interviews, on-site visits, evaluation of cooperative, member and partner information, and participation in the advising process are used to evaluate the impact of efforts to re-engineer the supply chain for independent farmers through cooperative organization. Specific examples of marketing channel development and operation for Wallace melons and mutton represent implementation of strategic plans. The case also reviews the cooperative’s credit system, designed increase access to and reduced cost of funds for members, use of alternative market venues, and horizontal expansion through tourism.

A note on transition, turbulent length scales and transport in differentially rotating flows

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this note we address the issue of hydrodynamical instabilities in Astrophysical rotating shear flows in the light of recent publications focused on the possibility for differential rotation to trigger and sustain turbulence in the absence of a magnetic field. We wish to present in a synthetic form the major arguments in favor of this thesis along with a simple schematic scenario of the transition to and self-sustenance of such turbulence. We also propose that the turbulent diffusion length scale scales as the local Rossby number of the mean flow. A new prescription for the turbulent viscosity is introduced. This viscosity reduces to the so-called beta-prescription in the case of velocity profiles with a constant Rossby number, which includes Keplerian rotating flows.

description: At 2017, Victor Campanelli remembered the history of his family’s business – the AgroPastoril Campanelli farm. His thoughts were back to the challenges that his father had faced, including the investments on an integrated production system that contributed to the family’s business growth. The production of cattle, sugarcane, and corn are all part of this integration system that has helped the Campanelli family to develop a successful business model. Currently, AgroPastoril Campanelli has three main production activities: beef, sugarcane, and corn. With these activities, a sustainable circle was created to guarantee more efficiency in economic, environmental and social terms. As Victor Campanelli says, ‘there is a perfect synergy between sugarcane, moisture, corn, and cattle. Not just because of the better land and labor use, but also because of the inputs economy and the productivity improvement, both in agriculture and livestock’. However, the present time requires a new investment cycle, leading the whole family to consider new market opportunities, especially regarding farmer’s new demands. What should we do and where should we invest? Should we improve efficiency or open new areas? Should we invest in new agriculture enterprises or start new business outside agricultural market? Those and other crucial questions were posed by Victor Campanelli thinking on potential growth strategies for AgroPastoril Campanelli.

Quite good results for the wrapping probabilities, correlation length critical exponent and critical concentration are obtained for the square, simple cubic, HCP and hexagonal lattices by using relatively small systems. We also confirm the universal aspect of the wrapping probabilities regarding site and bond dilution.

description: Using a public goods experiment with heterogeneous income and marginal-per-capita-returns (MPCR), this paper investigates the main drivers of behavior for high- and low-income individuals playing separately and in mixed groups. A finite mixture model was used to split each income type into two categories. While a third of low-income individuals were “free-riders”, the dominant portion was classified as “opportunists”, who try to benefit from the presence of high-income individuals by encouraging contributions through cooperation. “Free-riders” were far less among high-income individuals, where the overruling majority were “selfists” who, due to self-interest and caution, contribute less when low-income individuals are present.

description: The rapid growth of online advertising has fueled the growth of ad-blocking software, such as new ad-blocking and privacy-oriented browsers or browser extensions. In response, both ad publishers and ad networks are constantly trying to pursue new strategies to keep up their revenues. To this end, ad networks have started to leverage the Web Push technology enabled by modern web browsers. As web push notifications (WPNs) are relatively new, their role in ad delivery has not been yet studied in depth. Furthermore, it is unclear to what extent WPN ads are being abused for malvertising (i.e., to deliver malicious ads). In this paper, we aim to fill this gap. Specifically, we propose a system called PushAdMiner that is dedicated to (1) automatically registering for and collecting a large number of web-based push notifications from publisher websites, (2) finding WPN-based ads among these notifications, and (3) discovering malicious WPN-based ad campaigns. Using PushAdMiner, we collected and analyzed 21,541 WPN messages by visiting thousands of different websites. Among these, our system identified 572 WPN ad campaigns, for a total of 5,143 WPN-based ads that were pushed by a variety of ad networks. Furthermore, we found that 51% of all WPN ads we collected are malicious, and that traditional ad-blockers and malicious URL filters are remarkably ineffective against WPN-based malicious ads, leaving a significant abuse vector unchecked.

description: We propose an inductive method to measure critical current density $J_c$ in bulk superconductors. In this method, an ac magnetic field is generated by a drive current $I_0$ flowing in a small coil mounted just above the flat surface of superconductors, and the third-harmonic voltage $V_3$ induced in the coil is detected. We present theoretical calculation based on the critical state model for the ac response of bulk superconductors, and we show that the third-harmonic voltage detected in the inductive measurements is expressed as $V_3= G_3ωI_0^2/J_c$, where $ω/2π$ is the frequency of the drive current, and $G_3$ is a factor determined by the configuration of the coil. We measured the $I_0$-$V_3$ curves of a melt-textured $\rm YBa_2Cu_3O_{7-δ}$ bulk sample, and evaluated the $J_c$ by using the theoretical results.

description: By randomizing the order in which participants perform a cognitive test and a food choice task in a controlled experiment, we show that overweight and obese participants exhibit an anticipatory food reward effect. Eye tracking data revealed that temptation, in the form of visual attention, and emotional arousal was higher under low cognitive resources. The anticipation of food reward helped enhance the mental resources of overweight and obese individuals and improve their performance in a cognitive test. However, there was no anticipation reward among normal weight participants. Our results support the notion that rewarding processes underlying food intake present similar patterns to those behind other forms of addiction.

description: Risk-efficient centre pivot investment strategies can be selected by taking into account both cumulative probability distributions of the estimated after-tax income from alternative centre pivot investments and the producer's preferences. Ordinary and generalized stochastic dominance criteria are used as decision-making criteria. Eighteen typical centre pivot systems were identified on the basis of differences in capacity, size, pumping height and soil type. The estimated net present values for a wheat/maize/cotton rotation crop system were calculated for each investment by taking production and price risks into consideration. Stochastic dominance criteria facilitate the selection of the risk-efficient strategies that will be preferred by different decision-makers, on the basis of the total probability distributions of outcomes. In most cases stochastic dominance of the first degree gives a single strategy which is dominant. Only by using the generalized stochastic dominance criterion can investment strategies be placed in order of preference. However, in this case decision-makers with varying degrees of risk-sensitivity do not differ in respect of centre pivot investment strategics that would satisfy their spesific preferences.

description: We study baryon-number-violating processes, including proton and bound neutron decays and $n-\bar n$ oscillations, in a left-right-symmetric (LRS) model in which quarks and leptons have localized wavefunctions in extra dimensions. In this model we show that, while one can easily suppress baryon-number-violating nucleon decays well below experimental bounds, this does not suppress $n-\bar n$ transitions, which may occur at levels comparable to current limits. This is qualitatively similar to what was found in an extra-dimensional model with a Standard-Model low-energy effective field theory (SMEFT). We show that experimental data imply a lower limit on the mass scale $M_{n \bar n}$ characterizing the physics responsible for $n-\bar n$ oscillations in the LRS model that is significantly higher than in the extra-dimensional model using a SMEFT and explain the reason for this. Our results provide further motivation for new experiments to search for $n - \bar n$ oscillations.

description: The SunPy Project developed a 13-question survey to understand the software and hardware usage of the solar physics community. 364 members of the solar physics community, across 35 countries, responded to our survey. We found that 99$\pm$0.5% of respondents use software in their research and 66% use the Python scientific software stack. Students are twice as likely as faculty, staff scientists, and researchers to use Python rather than Interactive Data Language (IDL). In this respect, the astrophysics and solar physics communities differ widely: 78% of solar physics faculty, staff scientists, and researchers in our sample uses IDL, compared with 44% of astrophysics faculty and scientists sampled by Momcheva and Tollerud (2015). 63$\pm$4% of respondents have not taken any computer-science courses at an undergraduate or graduate level. We also found that most respondents utilize consumer hardware to run software for solar-physics research. Although 82% of respondents work with data from space-based or ground-based missions, some of which (e.g. the Solar Dynamics Observatory and Daniel K. Inouye Solar Telescope) produce terabytes of data a day, 14% use a regional or national cluster, 5% use a commercial cloud provider, and 29% use exclusively a laptop or desktop. Finally, we found that 73$\pm$4% of respondents cite scientific software in their research, although only 42$\pm$3% do so routinely.

description: Overwintering of livestock has been regarded as a major problem in the Drakensberg grazing regions, which are characterized by high rainfall, cold winters and uneven topography. The latter limits arable land and this leads to mixed farming. The natural vegetation is predominantly sour veld; natural grazing becomes unpalatable and indigestible in winter. Farmers have for long handled this livestock overwintering problem by moving animals to grazing outside the region. The practice has been dying out. Linear programming was used to determine optimal livestock and cropping systems. The most profitable farming enterprise was shown to be dairying. Grazing and arable land should supply the dairy herd with its roughage needs and after these needs are satisfied, the remainder of arable land should be used for cash crops (maize and dry beans), leaving no room for either beer cattle or woolled sheep. If the farmer does not want to keep dairy cattle, his second best choice - with much lower profitability - is a combination of cash crops and woolled sheep. Sheep numbers have to be adjusted to the ability of natural grazing and crop residues to sustain their nutritional needs. It docs not pay to use arable land to produce feed or pastures for sheep. Beef cattle cannot compete economically with either dairy cattle, sheep or cash crops. Thus, the main problem in this region is not overwintering, but rather selection of optimal farming systems.

description: We consider the (1+1)-dimensional ${\cal N}=(2,2)$ super Yang--Mills theory which is obtained by dimensionally reducing ${\cal N}=1$ super Yang--Mills theory in four dimension to two dimensions. We do our calculations in the large-$N_c$ approximation using Supersymmetric Discrete Light Cone Quantization. The objective is to calculate quantities that might be investigated by researchers using other numerical methods. We present a precision study of the low-mass spectrum and the stress-energy correlator $$. We find that the mass gap of this theory closes as the numerical resolution goes to infinity and that the correlator in the intermediate $r$ region behaves like $r^{-4.75}$.

description: The quantity of wheat supplied in the RSA and the different production regions arc significantly innucnced by a variety of factors, including time, climate, wheat prices, prices of production substitutes such as maize, mutton, wool and sorghum, and input costs. By using multiple regression techniques the effects of these factors on the area under wheat and the production of wheat in the various production areas were isolated and quantified The different supply equations seem to yield significant results within acceptable statistical norms and can thus be fruitfully used for predictions.

description: We report on our realization of a high power holmium doped fiber laser, together with the validation of our numerical simulation of the laser. We first present the rare absolute measurements of the physical parameters that are mandatory to model accurately the laser-holmium interactions in our silica fiber. We then describe the realization of the clad-pumped laser, based on a triple-clad large mode area holmium (Ho) doped silica fiber. The output signal power is 90 W at 2120 nm, with an efficiency of about 50% with respect to the coupled pump power. This efficiency corresponds to the state of the art for clad-pumped Ho-doped fiber lasers in the 100 W power class. By comparing the experimental results to our simulation, we demonstrate its validity, and use it to show that the efficiency is limited, for our fiber, by the non-saturable absorption caused by pair induced quenching between adjacent holmium ions.

description: A suivey of milk and poultry purchases was made of villagers and cafe owners in a rural lowland area of Lesotho. The purpose of the survey was to: 1) assess the current local market demand, 2) obtain baseline information on purchases of these products, 3) test a methodology for doing rural market suiveys. The survey area was selected because it was a potential site for new milk or poultry production. Villagers were systematically selected (every 5th) from a list of names provided by the village chief, and interviewed by enumerators. Villagers were informed as to the purpose of the survey and were forthcoming as to current and potential future purchases. Responses concerning current purchases seemed reasonable and reliable, however, responses concerning future purchases seemed to be over stated. Most of the milk purchased was long life, followed by fresh unpasteurized, sour milk and other types of milk. In contrast fresh milk was preferred to long life by a ratio of 5 to 1. Most of the poultry purchased was live chickens, followed by whole frozen and frozen chicken parts, preferences were also in this order. Purchases of milk was inelastic relative to household cash income, household surplus income and household size. Purchase of milk did not increase with increasing per capita income (household income divided by household size). As income rose, purchase of poultry also rose. The elasticity of poultry purchases was evident with increasing household income. Salary income or surplus income were poorer predictors of poultry purchases than total income. This suggests that income from non-salaried sources (sale of beer, crafts, and business) was preferentially spent on poultry.

description: The hetero junction between the different materials often gives the rectification effect; e.g., pn junction is used for diode. On the other hand, the Josephson junction between the two superconductors is assumed to show symmetric response between the two directions of the current, i.e., the voltage drop $V$ is anti-symmetric with respect to the sign change of the current $I$. However, there should be an asymmetry between the states of charge accumulation on right and left sides of the Josephson junction, which can lead to the nonreciprocal responses. Here we demonstrate theoretically that nonreciprocal $I$-$V$ characteristic appears due to this charging energy difference both in the classical and quantum regimes. This result will pave a route to design and develop the Josephson diode.
