Farm Management - Back to Basics
Creators: name: Stephens, Richard
Publisher: name: Unknown
Year: 1993
Subjects: Farm Management

description: Two farm management surveys showed that both farm advisers and farmers believe in similar management concepts. However, there were large differences between how these concepts were made available by the advisers and how the farmers wanted them presented. The challenge therefore, was to develop and promote a simple management package, encompassing those concepts, which could be used by the majority of farmers. Surveys of farmers and farm advisers, reviews of relevant farm management systems and research and trials involving farmers resulted in a simple, non-computerised management package. The success of this package, called Farm Biz, has lead to a fully revised second edition being produced within 12 months of its initial launch.

Limits of ultra-high-precision optical astrometry: Stellar surface structures
Creators: name: Eriksson, Urban

Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the astrometric effects of stellar surface structures as a practical limitation to ultra-high-precision astrometry, e.g. in the context of exoplanet searches, and to quantify the expected effects in different regions of the HR-diagram. Stellar surface structures are likely to produce fluctuations in the integrated flux and radial velocity of the star, as well as a variation of the observed photocentre, i.e. astrometric jitter, and closure phase. We use theoretical considerations supported by Monte Carlo simulations to derive statistical relations between the corresponding astrometric, photometric, and radial-velocity effects. For most stellar types the astrometric jitter due to stellar surface structures is expected to be of order 10 micro-AU or greater. This is more than the astrometric displacement typically caused by an Earth-size exoplanet in the habitable zone, which is about 1-4 micro-AU for long-lived main-sequence stars. Only for stars with extremely low photometric variability (<0.5 mmag) and low magnetic activity, comparable to that of the Sun, will the astrometric jitter be of order 1 micro-AU, suffcient to allow the astrometric detection of an Earth-sized planet in the habitable zone. While stellar surface structure may thus seriously impair the astrometric detection of small exoplanets, it has in general negligible impact on the detection of large (Jupiter-size) planets and on the determination of stellar parallax and proper motion. From the starspot model we also conclude that the commonly used spot filling factor is not the most relevant parameter for quantifying the spottiness in terms of the resulting astrometric, photometric and radial-velocity variations.

Subjects: Farm Management
Labor and Human Capital

description: Personnel management becomes important in Japan’s farming as the number of hired labor is increasing. The two features of current farm employment are the labor shortage caused by aging of operators and reduced family labor, and emerging corporate farming under deregulations of farm policies. Survey on floriculture shows that the operators endeavor to maintain friendly relationships with the employees and harmonious atmosphere among them to keep workers longer at the expense of work efficiency. Management methods achieving the efficiency and good personnel relationships simultaneously are required. Establishment of sound business organization guaranteeing high quality of working life including competitive income and career advancement is needed to recruit skillful regular workers. Educational programs on personnel management and work regulations for farmers are recommended.

description: Giant mole-rats (Fukomys mechowii) are remarkably long-lived subterranean rodents (maximum recorded lifespan as reported here greater than 26 years) that live in families with one reproductive pair (breeders) and their non-reproductive offspring (non-breeders). Previous studies have shown that breeders live on average approximately twice as long as non-breeders, a finding contradicting the classic trade-off between reproduction and lifespan. Because recent evidence points to the hypothalamic-pituitary-adrenal axis as playing an important role in shaping the pace of ageing in mole-rats, we analysed the influence of the social environment of giant mole-rats on intrafamilial aggression levels, indicators of long-term stress, and, ultimately, mortality. Behavioural data indicated that family constellation, especially the presence or the absence of parents, influences agonistic behaviour. As a measure of long-term stress, we established a non-invasive method of extracting and measuring cortisol from hair of giant mole-rats. Interestingly, orphaned non-breeders exhibited significantly lower levels of cortisol and lower mortality rates than did non-breeders living with both parents. Because hypercortisolism is harmful in the long-term, intrafamilial stress could help explain the earlier onset of senescence in non-breeders, resulting in a shorter lifespan. Our findings suggest that the social environment should be considered as a further factor in ageing studies involving group-living animals.

description: In the early 1950s it was accepted in China the Soviet model of socialist economic system with highly centralized planning economic management system. This model has been implemented until 197S, when the Government of China begun the economic system reform. The three stages of this reform have ill ready been experienced: the first stage (1973-1984) included the rural economic system reform, the second stage (1984-1987) with the urban economic system reform and the third stage ( after 1937) when the political reform has begun.
This paper examines the practice of the Chinese reform and development of the enterprises, particularly agribusiness ones .

We obtain the allowed parameter space constrained from the Higgs decays to gauge Bosons at LHC, LEP II data and electro-weak precision measurements. The muon and electron MDM's are then explained within a common parameter space for different sets of allowed couplings and masses of the model particles.

description: Lattice simulation of supersymmetric gauge theories is not straightforward. In some cases the lack of manifest supersymmetry just necessitates cumbersome fine-tuning, but in the worse cases the chiral and/or Majorana nature of fermions makes it difficult to even formulate an appropriate lattice theory. We propose to circumvent all these problems inherent in the lattice approach by adopting a non-lattice approach in the case of one-dimensional supersymmetric gauge theories, which are important in the string/M theory context.

Screening for congenital dislocation of the hip in infants in British Columbia
Creators: name: Fulton Fraser, Jane
Publisher: name: University of British Columbia
Year: 2010

description: Congenital Dislocation of the Hip in infants is a topic of screening interest in British Columbia. When a case of Congenital Dislocation of the Hip is not diagnosed and treated in the neonatal period, the infant may later require surgical care. In British Columbia, 94% of surgical cases for Congenital Dislocation of the Hip come from unscreened communities which produce only 66% of the live births in the province. A cost-minimization analysis of screening and conservative treatment versus no screening and surgery shows that the cost of surgical care is more than three times greater. This thesis proposes that the province extend screening services to all Obstetrical Units in British Columbia and train physicians and nurses to do the screening. A suggestion is also made to incorporate hip screening into a comprehensive neonatal developmental screening package.

description: In order to study the possible superconductivity at the polar surfaces of 1111-type iron-based superconductors, which is doped with a large amount of holes in spite of the electron doping in bulk materials, we have performed angle-resolved photoemission spectroscopy (ARPES) studies on superconducting PrFeAsO$_{1-y}$~crystals. We have indeed observed the opening of a superconducting gap on surface-derived hole pockets as well as on a bulk-derived hole pocket. The superconducting gap is found to open on the surface-derived hole pockets below the bulk $T_c$, which suggests that the surface superconductivity is possibly induced by proximity effect from the bulk. We have also observed the opening of a large pseudogap on the surface-derived hole pockets, which is similar to the pseudogap in 122-type bulk superconductors doped with a smaller amount of holes. This suggests that the opening of a large pseudogap is a characteristic property of hole-doped iron-based superconductors.

description: On the basis of empiric data gathering and dynamic planning calulations, this investigation analyses the decisive planning hindrances for agricultural enterprises in the new states after the change to market economy. With dynamic planning calculations for typical enterprises of different legal and business forms the optimum development of these enterprises for a ten year period is described and the influence of alternative location and support conditions analysed. Apart from the disadvantages in the area of the decision making structures, which can be described only insufficiently in an quantitative model, the results of the model calculations indicate, that the legal successors of the APCs (Agricultural Production Cooperatives) are thoroughly able to fulfill the requirements for a stable enterprise development. This can only be successful if through in time rationalisation and extension investments the future production guidelines are taken into account and the workforce of the enterprises can be adapted to the requirement. This statements are also true for partnerships, that originated in an APC and are now operated under the management of a trust. Though the usually very low equity capitalisation and relatively high fixed cost burden of these enterprises restricts their development opportunities considerably. On the other hand, partnerships with financially strong western partners and an efficient management can be profitable even under less favourable frame conditions. In this case a stable enterprise development and operational growth can be achieved largely by oneself. Re- and newly established family farms have, contrary to larger enterprises with foreign labour, no problems in the area of working motivation. Under the condition, that the scale of the production can be adapted to the labour capacity of the family and the financing of necessary modernisation measures is guaranteed, the ordinary planning model for this group of enterprises indicates an ensured existential development.

description: Experimental bounds on induced vacuum magnetic birefringence can be used to improve present photon-photon scattering limits in the electronvolt energy range. Measurements with the PVLAS apparatus (E. Zavattini {\it et al.}, Phys. Rev. D {\bf77} (2008) 032006) at both $λ= 1064$ nm and 532 nm lead to bounds on the parameter {\it A$_{e}$}, describing non linear effects in QED, of $A_{e}^{(1064)} < 6.6\cdot10^{-21}$ T$^{-2}$ @ 1064 nm and $A_{e}^{(532)} < 6.3\cdot10^{-21}$ T$^{-2}$ @ 532 nm, respectively, at 95% confidence level, compared to the predicted value of $A_{e}=1.32\cdot10^{-24}$ T$^{-2}$. The total photon-photon scattering cross section may also be expressed in terms of $A_e$, setting bounds for unpolarized light of $σ_{γγ}^{(1064)} < 4.6\cdot10^{-62}$ m$^{2}$ and $σ_{γγ}^{(532)} < 2.7\cdot10^{-60}$ m$^{2}$. Compared to the expected QED scattering cross section these results are a factor of $\simeq2\cdot10^{7}$ higher and represent an improvement of a factor about 500 on previous bounds based on ellipticity measurements and of a factor of about $10^{10}$ on bounds based on direct stimulated scattering measurements.

description: Decentralising the Web is a desirable but challenging goal. One particular challenge is achieving decentralised content moderation in the face of various adversaries (e.g. trolls). To overcome this challenge, many Decentralised Web (DW) implementations rely on federation policies. Administrators use these policies to create rules that ban or modify content that matches specific rules. This, however, can have unintended consequences for many users. In this paper, we present the first study of federation policies on the DW, their in-the-wild usage, and their impact on users. We identify how these policies may negatively impact "innocent" users and outline possible solutions to avoid this problem in the future.

description: The maximum price of milk quota is the price a dairy farmer can afford to pay based on the expected future cash flows. This price strongly depends on the variable costs per additional kilogram of milk, the marginal income tax rate and the duration of the EC quota system. Based on a duration of 20 years, dairy farmers realizing low variable costs and facing high tax rates are in a good posisition to compete succesfully on the milk quota market.

description: Penrose's 1979 Weyl curvature hypothesis (WCH) \cite{WCH} assumes that the universe began at a very low gravitational entropy state, corresponding to zero Weyl curvature, namely, the FLRW universe. This is a simple assumption with far-reaching implications. In classical general relativity the most general cosmological solutions of the Einstein equation are that of the BKL-Misner inhomogeneous mixmaster types. How could WCH and BKL-M co-exist? An answer was provided in the 80s with the consideration of quantum field processes such as vacuum particle creation, which was copious at the Planck time ($10^{-43} sec$), and their backreaction effects were shown to be so powerful as to rapidly damp away the irregularities in the geometry. It was proposed that the vacuum viscosity due to particle creation can act as an efficient transducer of gravitational entropy (large for BKL-M) to matter entropy, keeping the universe at that very early time in a state commensurate with the WCH. In this essay I expand the scope of that inquiry to a broader range, asking how the WCH would fare with various cosmological theories, from classical to semiclassical to quantum, focusing on their predictions near the cosmological singularities (past and future) or avoidance thereof, allowing the Universe to encounter different scenarios, such as undergoing a phase transition or a bounce. We point out that regardless of what other processes may be present near the beginning and the end states of the universe, the backreaction effects of quantum field processes probably serve as the best guarantor of WCH because these vacuum processes are ubiquitous, powerful and efficient in dissipating the irregularities to effectively nudge the Universe to a near-zero Weyl curvature condition.

Expenditure patterns of households participating in the Farmer Support Programme of DBS A were analysed and compared with no-participants in two homelands of South Africa, Lebowa and Venda. It is evident from the results of this study that a high proportion of rural households in Lebowa and Venda is food insecured. Results also show that the provision of support services to subsistence farmers will help alleviate food insecurity.

As previously reported, the scattered intensity decreases strongly when the magnetic field is increased, but it remains measurable far above the second peak. The direct observation of Bragg peaks proves that the characteristics of a lattice are still present. No structural features related to a symmetry breaking, such as a liquid like or an amorphous state, can be observed. However, the associated scattered intensity is very low and is difficult to explain. We discuss the coexistence between two FLL states as a possible interpretation.

description: Infinitesimal perturbations in various systems showing spatiotemporal chaos (STC) evolve following the power laws of the Kardar-Parisi-Zhang (KPZ) universality class. While universal properties beyond the power-law exponents, such as distributions and correlations, and their geometry dependence, are established for random growth and related KPZ systems, the validity of these findings to deterministic chaotic perturbations is unknown. Here we fill this gap between stochastic KPZ systems and deterministic STC perturbations by conducting extensive simulations of a prototypical STC system, namely the logistic coupled map lattice. We show that the perturbation interfaces, defined by the logarithm of the modulus of the perturbation vector components, exhibit the universal, geometry-dependent statistical laws of the KPZ class, despite the deterministic nature of STC. We demonstrate that KPZ statistics for three established geometries arise for different initial profiles of the perturbation, namely point (local), uniform, and "pseudo-stationary" initial perturbations, the last being the statistically stationary state of KPZ interfaces given independently of the Lyapunov vector. This geometry dependence lasts until the KPZ correlation length becomes comparable to the system size. Thereafter, perturbation vectors converge to the unique Lyapunov vector, showing characteristic meandering, coalescence, and annihilation of borders of piece-wise regions that remain different from the Lyapunov vector. Our work implies that the KPZ universality for stochastic systems generally characterizes deterministic STC perturbations, providing new insights for STC, such as the universal dependence on initial perturbation and beyond.

description: The liquid argon ionization current in a sampling calorimeter cell can be analyzed to determine the energy of detected particles. In practice, experimental artifacts such as pileup and electronic noise make the inference of energy from current a difficult process. The beam intensity of the Large Hadron Collider will be significantly increased during the Phase-II long shut down of 2025-2027. Signal processing techniques that are used to extract the energy of detected particles in the ATLAS detector will suffer a significant loss in performance under these conditions. This paper compares the presently used optimal filter technique to convolutional neural networks for energy reconstruction in the ATLAS liquid argon hadronic end cap calorimeter. In particular, it is shown that convolutional neural networks trained with an appropriately tuned and novel loss function are able to outperform the optimal filter technique.

description: In this paper, we present the final results of our experiment on photon-axion oscillations in the presence of a magnetic field, which took place at LULI (Laboratoire pour l'Utilisation des Lasers Intenses, Palaiseau, France). Our null measurement allowed us to exclude the existence of axions with inverse coupling constant $M>9.\times 10^5$ GeV for low axion masses and to improve the preceding BFRT limits by a factor 3 or more for axion masses $1.1 {meV}
Failure of the displaced-squeezed state for spin-boson models in the thermodynamic limit

description: We present an analysis of a variational coherent-squeezed state that has been discussed in the literature as a potential ground state for the spin-boson model. We show that when the system-size scaling of the spin-bath coupling is included properly, all squeezing effects and non-universal physics vanish in the thermodynamic limit. We also present finite-size corrections to the renormalisation of the spin's coherence, showing that squeezing effects are also absent to leading order in the inverse bath-size.

Relationship Between Distribution of Land Ownership, Income Distribution and Population Distribution: Some Theoretical Consideration and Empirical Evidences from Irang
Creators: name: Arsalanbod, Mohamadreza
Publisher: name: Unknown
Year: 1993
Subjects: Land Economics/Use

description: In this paper, it is argued that there is a strong relationship between structures of "population distribution" and "distribution of land ownership and distribution of income" . In other words distribution of land and income" is a "push" factor in rural/agriculturai/urban/ non agricultural migration. The argument is mainly theoretical. A limited empirical evidence from Iran is consistent with the implication of the theoretical discussion. namely, the higher the inequality of land and income distribution within the rural areas, the higher the rural agricultural out-migration, and therefore more concentration of population in urban areas.

Discretized Multinomial Distributions and Nash Equilibria in Anonymous Games

description: We show that there is a polynomial-time approximation scheme for computing Nash equilibria in anonymous games with any fixed number of strategies (a very broad and important class of games), extending the two-strategy result of Daskalakis and Papadimitriou 2007. The approximation guarantee follows from a probabilistic result of more general interest: The distribution of the sum of n independent unit vectors with values ranging over {e1, e2, ...,ek}, where ei is the unit vector along dimension i of the k-dimensional Euclidean space, can be approximated by the distribution of the sum of another set of independent unit vectors whose probabilities of obtaining each value are multiples of 1/z for some integer z, and so that the variational distance of the two distributions is at most eps, where eps is bounded by an inverse polynomial in z and a function of k, but with no dependence on n. Our probabilistic result specifies the construction of a surprisingly sparse eps-cover -- under the total variation distance -- of the set of distributions of sums of independent unit vectors, which is of interest on its own right.

On the Low Energy Spectra of the Nonsupersymmetric Heterotic String Theories

description: The ten dimensional string theories as well as eleven dimensional supergravity are conjectured to arise as limits of a more basic theory, traditionaly dubbed M--theory. This notion is confined to the ten dimensional supersymmetric theories. String theory, however, also contains ten dimensional nonsupersymmetric theories that have not been incorporated into this picture. In this note we explore the possibility of generating the low energy spectra of various nonsupersymmetric heterotic string vacua form the Horava--Witten model. We argue that this can be achieved by imposing on the Horava--Witten model an invariance with respect to some extra operators which identify the orbifold fixed planes in a nontrivial way, and demonstrate it for the E_8 and SO(16)XSO(16) heterotic string vacua in ten dimensions.

Robustness of equilibrium off-diagonal current fluctuation against localization of electron states in macroscopic two-dimensional systems

description: We study the off-diagonal current fluctuation in a macroscopic quantum system measured in an ideal manner that is as close as possible to the classical ideal measurement. We show rigorously that not only extended but also localized states contribute to the off-diagonal current fluctuation. This result contrasts with the fact that only the extended states affect the off-diagonal (Hall) conductivity and apparently contradicts the naive expectation from the fluctuation-dissipation theorem that might directly connect these two quantities. More specifically, we study the off-diagonal current fluctuation in a disordered two-dimensional electron system in a strong magnetic field at low temperatures. The fluctuation is almost unchanged from that of the pure system reflecting the property mentioned above, being approximately proportional to the Landau level filling factor with high accuracy. Our finding paves the way to estimate the filling factor and the electron density from the off-diagonal current fluctuation observed in macroscopic systems.

World Trade in Fruit and Vegetables

Subjects: International Relations/Trade

description: During the last decade the international trade of fruit and vegetables has been characterized by comparatively fast increase in value and lower level of protection as compared to other agricultural products. The share of fruit and vegetables in whole trade of agricultural products has increased as a result of such tendencies. The highest increase in surplus was recorded in Spain, Netherlands and Turkey. Also, the rise in export from the Southern hemisphere countries was very intense. Decisive factors of that expansion were better transportability and storage facilities, impact of multinational distribution companies and exceptional increase in export of Chile. The Mediterranean countries as a whole (although they are still on the lead in world production and export) are loosing their market share and that is especially visible in countries non-members of EC.

Standardizing the hospital’s case load for diagnostic mix and resource use : a comparison of the RNI and information theory indices
Creators: name: Hardwick, Jill Margaret
Publisher: name: University of British Columbia
Year: 2010

description: Hospital cost containment is a priority for provincial governments in Canada and reimbursing agencies in the United States—a consequence of the dramatic rise in the rate of hospital cost increases. Studies have shown that this increase is mainly due to an increase in resource use per patient day—more intensive labour; more laboratory tests, drugs; more sophisticated technology. The level of resource use obviously varies for different cases, depending on the nature of the patient's illness. The problems facing reimbursing agencies are that of reducing the rate of growth of hospital expenditures and an equitable reimbursement of hospitals, taking adequate account of their diverse case mix. Simple measures of hospital output such as the number of cases or the number of patient days assume an homogeneous output. As a consequence, various standardization techniques have been developed to standardize for case mix variation, initially, output standardization was attempted using proxies for case mix such as the number of services and facilities available in a hospital. Later, diagnosis itself was used and weighted in a variety of different ways. The purpose of this study is to compare two approaches to case mix standardization—information theory and the Resource Need Index. These approaches rely on different assumptions. Hence the intention is to critically examine their conceptual bases and compare their relative ability to explain inter-hospital cost differences in Alberta. The empirical results show that the information theory measure performs better than the Resource Need Index in explaining hospital costs. An illustrative example is given to show how this technique can be built into the budget setting process in Alberta to effect a more equitable distribution of resources among hospitals.

description: The present paper analyzes attitude of the rural youth towards general and professional education of farmers, as recorded in four villages in Croatia. The researches I were carried out in 1968, 1978, 1988, within the project analyzing the socio-economic changes. Four groups of rural youth have been encompassed: farmers, those working off the farm, high-school and college students, and elementary school students of the eighth grade. There where the traditional agricultural production prevails, 50 - 60 percent of the respondents agrees to a certain or to a full degree that the farmers need no school education. When the conditions are those of modern agriculture, on the contrary, almost nine tenths of the young express their positive attitude towards general and professional education. As compared to other social groups of the rural youth, the young farmers have expressed pronouncedly conservative attitude towards both general and professional education. Also, the participants in less developed villages have shown more negative attitude towards education than those from more developed surroundings.

description: We consider strongly gravitating configurations consisting of coupled real Higgs scalar field and vector (Proca) field of mass $μ_P$. For such a system, we find static regular axially symmetric solutions describing asymptotically flat configurations which may be referred to as Proca-Higgs miniboson stars, since their total mass and spatial dimension are of order $M_{\text{Pl}}^2/μ_P$ and $μ_P^{-1}$, respectively.The system possesses an axially symmetric dipole field and may be regarded as a Proca dipole.
