description: The conditional distribution of the next outcome given the infinite past of a stationary process can be inferred from finite but growing segments of the past. Several schemes are known for constructing pointwise consistent estimates, but they all demand prohibitive amounts of input data. In this paper we consider real-valued time series and construct conditional distribution estimates that make much more efficient use of the input data. The estimates are consistent in a weak sense, and the question whether they are pointwise consistent is still open. For finite-alphabet processes one may rely on a universal data compression scheme like the Lempel-Ziv algorithm to construct conditional probability mass function estimates that are consistent in expected information divergence. Consistency in this strong sense cannot be attained in a universal sense for all stationary processes with values in an infinite alphabet, but weak consistency can. Some applications of the estimates to on-line forecasting, regression and classification are discussed.
Managing My Farm into the 21st Century

description: The 2,000 acre family farm is situated on the east coast of England in a rainfall zone which has a 10-year average of 19.5 inches. The alluvial silt soils support a 6-year arable and vegetable rotation. The main cash contributor is the potato crop, marketed through the vertically integrated packing operation which supplies direct to the retail multiples. Most other crops are marketed co-operatively. The challenge for the future in the UK and Europe into the twenty first century is in improved marketing and getting closer to the customer, addressing the food safety and environmental concerns of the consumer, and at the same time embracing any new technologies and techniques which drive down costs.

description: Although they are sometimes considered problematic to grasp by students, the concepts behind non-Euclidean geometry can be taught using astronomical images. By using photographs of the Moon taken with a smartphone through a simple telescope, we were able to introduce these concepts to high-school students and college newcomers. By recognizing different Moon geological structures within the photograph, we teach students how to calculate distances of mountain ranges or areas of craters on the Moon's surface, introducing the notions of geodesics and spherical triangles. Furthermore, students can empirically see that the correct estimations for the actual values cannot be obtained using flat geometry. Instead, by using three--dimensional curved geometry, precise estimates of lengths and areas of geological elements in the Moon can be computed with less than 4\% error. These procedures help students understand, concretely, non-Euclidean geometry concepts.

description: The surface morphologies of poly(chloro-p-xylylene) films were measured using atomic force microscopy and analyzed within the frame work of the dynamic scaling theory. The evolution of polymer films grown with fixed experimental parameters showed drastic changes of dynamic roughening behavior, which involve unusually high growth exponent (beta = 0.65+-0.03) in the initial growth regime, followed by a regime characterized by beta~0, and finally a crossover to beta = 0.18+-0.02 in a steady growth regime. Detailed scaling analysis of the surface fluctuation in Fourier space in terms of power spectral density revealed a gradual crossover in the global roughness exponent, analogous to a phase transition between two equilibrium states, from a morphology defined by alpha=1.36+-0.13 to the other morphology characterized by alpha=0.93+-0.04 as the film thickness increases. Our experimental results which significant deviate from the well established descriptions of film growth clearly exhibit that the dynamic roughening of polymer film is deeply affected by strong molecular interactions and relaxations of polymer chains.

description: The effects of interactions between the changing global management environment, successful farm managers andfarm management educators require urgent consideration if management education for farm management and agribusiness is to meet the challenges of the 21st Century. A paradigm shift in the way the global food andfibre system operates is placing new demands on farm managers and as a consequence significant changes in farm management education are required. Management education in the 21st Century will be driven by consumer demands for quality, value, accessibility, flexibility and relevance. Continuing rapid change will require educators and their organisations to be forward looking and responsive to emerging consumer needs. Competition between education providers will be intense and unless farm management educators develop the required capabilities potential clients will be lost to general management programs. Farm management educators who successfully respond to the changing demands will be part of an exciting new era with considerable opportunities in old and new learner markets.

description: We investigate scaling and memory effects in return intervals between price volatilities above a certain threshold $q$ for the Japanese stock market using daily and intraday data sets. We find that the distribution of return intervals can be approximated by a scaling function that depends only on the ratio between the return interval $τ$ and its mean $$. We also find memory effects such that a large (or small) return interval follows a large (or small) interval by investigating the conditional distribution and mean return interval. The results are similar to previous studies of other markets and indicate that similar statistical features appear in different financial markets. We also compare our results between the period before and after the big crash at the end of 1989. We find that scaling and memory effects of the return intervals show similar features although the statistical properties of the returns are different.

description: Curriculum development must start with a needs analysis - namely consulting practitioners. This paper uses data which indicates how farmers/farm managers spend their working time and the management skills they employ. Also, farmers/farm managers have been surveyed for their views on management skills they consider they will need and the challenges they will face as they manage farms into the 21st Century. Drawing on the information collected from practising farmers/farm managers some basic principles for future curriculum development and delivery are then proposed for farm management teaching into the 21st Century. While it will continue to be important for future managers to be technically sound and up to date with basic farm management skills - undoubtedly, new challenges lie ahead. These will include teachers as regards new delivery methods, and learners in terms of new skills and technology.

Teaching Management into the 21st Century: A Southern Perspective
Creators: name: Agrawal, Ramesh C.
Publisher: name: Unknown
Year: 1997
Subjects: Farm Management

description: The main purpose of teaching management into the 21st Century, to a typical farm- household in the South, is to facilitate it to produce, on a sustainable basis and from the same or declining area of land, (i) more and better food for own and local consumption, and (ii) commodities for processing and export so as to improve its income and quality of life and to contribute to national development. To be effective, teaching should (i) be simple, economic, participative, and interactive and (ii) include women and younger generation. It does not necessarily mean drastic changes in the existing philosophy of management teaching to farm-household but does imply a significant improvement in application. To attain the desired results, its training should be accompanied by improved management on the part of extension agencies, farmers ’ organization, supporting services, and policy managers, whose lapses are often more responsible for the failure of the farmer to properly adopt and manage the extension advice, than the lack of sincere efforts on his part.

description: The purpose of the paper is to set the environment that managers will face as we move into the 21st century and to trace the implications for farm managers and for educators. Decision making will be more interactive with electronic delivery of management training and information. Computer models will have the capacity to easily interact and communicate between modules and to use larger data bases. The interface between the decision maker and analytical computer models will be more user friendly. Computer aids will have the flexibility to add or delete modules as needed As production becomes more integrated, management advisory services and educational programs will also be more integrated Public and private agencies will apply their comparative advantages to produce integrated and complementary programs. There will be more emphasis on the intangibles of management such as persomiel management and organizational skills. Successful managers will focus more attention on communications and monitoring performance.

Management of the Agricultural Economy in Sub-Saharan Africa After Structural Adjustment Programme

Year: 1997
Subjects: Farm Management

description: African economies, after having achieved a high rate of growth during the 1960s and early 1970s, started to decelerate in the 1980s and the 1990s. The major engine of growth for African countries during the decade of high growth was their exports of primary commodities to the developed market economies. The steady downward trend in African economies since the early 1970s constituted a source of major concern for many policy makers both at the national and international levels. Consequently, since the early 1980s many African countries have embarked on adjustment programmes, supported in most cases by Bretton Woods institutions to ameliorate the poor performance of their economies. Overall, the African experience does not seem to have conformed to the classical model of balance of payments adjustment mechanism. Especially, the unresponsiveness of agricultural export growth to exchange rate adjustment. In the light of the above it is proposed that structural adjustment policies in Africa should in addition to focusing on macro-economic stability be implemented in the context of recovery and growth. The vast agricultural resource base of many African countries points to the significant potential role of agriculture and its inter-relationship with overall growth. Hence it is proposed that more emphasis should be placed on the accelerated development of the agricultural sector in sub-Saharan Africa.

description: There is an increased interest in model agnostic search strategies for physics beyond the standard model at the Large Hadron Collider. We introduce a Deep Set Variational Autoencoder and present results on the Dark Machines Anomaly Score Challenge. We find that the method attains the best anomaly detection ability when there is no decoding step for the network, and the anomaly score is based solely on the representation within the encoded latent space. This method was one of the top-performing models in the Dark Machines Challenge, both for the open data sets as well as the blinded data sets.

description: A technique is proposed for creating nonground-state Bose-Einstein condensates in a trapping potential by means of the temporal modulation of atomic interactions. Applying a time-dependent spatially homogeneous magnetic field modifies the atomic scattering length. An alternating modulation of the scattering length excites the condensate, which, under special conditions, can be transferred to an excited nonlinear coherent mode. It is shown that there occurs a phase-transition-like behavior in the time-averaged population imbalance between the ground and excited states. The application of the suggested technique to realistic experimental conditions is analyzed and it is shown that the considered effect can be realized for experimentally available condensates.

description: The Hamiltonian of classical anti-de Sitter gravity is a pure boundary term on-shell. If this remains true in non-perturbative quantum gravity then i) boundary observables will evolve unitarily in time and ii) the algebra of boundary observables is the same at all times. In particular, information available at the boundary at any one time t_1 remains available at any other time t_2. Since there is also a sense in which the equations of motion propagate information into the bulk, these observations raise what may appear to be potential paradoxes concerning simultaneous (or spacelike separated) measurements of non-commuting observables, one at the asymptotic boundary and one in the interior. We argue that such potentially paradoxical settings always involve a breakdown of semi-classical gravity. In particular, we present evidence that making accurate holographic measurements over short timescales radically alters the familiar notion of causality. We also describe certain less intrinsically paradoxical settings which illustrate the above boundary unitarity and render the notion more concrete.

Painting and politics at the Royal Academy exhibition of 1832
Creators: name: Elliot, Bridget Jane
Publisher: name: University of British Columbia
Year: 2010

description: The Royal Academy exhibition of 1832 opened in London in the midst of a political crisis over the passage of the Great Reform Bill. An analysis of the critical response to four of the leading pictures in the exhibition: A Family Portrait by C.R. Leslie, The Preaching of Knox by David Wilkie, The Destroying Angel by William Etty, and Chiide Harold's Pilgrimage - Italy by J.M.W. Turner, provides evidence that the ongoing political conflict permeated the Academy exhibition. In an atmosphere of increasing tension caused by parliamentary deadlock and street rioting, art critics argued about the pictures' quality and meaning in highly politicized terms. This investigation focuses upon these four pictures and their critical reception, in order to probe the extent to which art and politics were connected at that specific historical moment. Documentary evidence of viewer responses is provided by anonymous reviews of the pictures which were published in ten major London newspapers and journals during the weeks following the opening of the show. The bias of each publication is carefully examined since, during the 1830's, most publications were highly partisan affairs, often receiving direct subsidies from particular interest groups. The analysis of these paintings offers a new perspective on the tensions, alignments, shifts, and ambiguities of British social classes and political parties in 1832. While the reception of Leslie's portrait points out the short-term divisions between Whigs and Tories over the issue of parliamentary reform, that of Wilkie1s history painting demonstrates that despite their differences, these two groups were united by a shared fear of the radical working class. Etty's academic sketch provides an example of how members of the conservative upper class rationalized rejecting the notion of reform, while Turner's landscape reveals how progressive middle-class reformers challenged tradition with a positive assertion of modernity. By examining the response to these pictures, one finds there is no clear separation between political and artistic spheres.

Year: 1997
Subjects: Productivity Analysis

description: Africa is the continent with the greatest potential for expansion of agricultural output through improved management practices. The writer has almost thirty years of experience of working in Eastern and Central Africa, coinciding with the emergence of the newly independant nations in that region. Great changes have taken place during this time in the agricultural industry and some of those are described in particular at farm level. The roles of both the private commercial sector and the subsistance producers are outlined and attention is given to resources and constraints which contribute to present management practices. Finally, an analysis of the potential for increased production is presented, taking into account global developments and showing how management may need to adapt to realise this potential.

A Haar-like Construction for the Ornstein Uhlenbeck Process

Publisher: name: arXiv
Year: 2007
Subjects: subject: Probability (math.PR)

description: The classical Haar construction of Brownian motion uses a binary tree of triangular wedge-shaped functions. This basis has compactness properties which make it especially suited for certain classes of numerical algorithms. We present a similar basis for the Ornstein-Uhlenbeck process, in which the basis elements approach asymptotically the Haar functions as the index increases, and preserve the following properties of the Haar basis: all basis elements have compact support on an open interval with dyadic rational endpoints; these intervals are nested and become smaller for larger indices of the basis element, and for any dyadic rational, only a finite number of basis elements is nonzero at that number. Thus the expansion in our basis, when evaluated at a dyadic rational, terminates in a finite number of steps. We prove the covariance formulae for our expansion and discuss its statistical interpretation and connections to asymptotic scale invariance.

description: Strong focus on development of rural areas in Norway, political guidelines and resource priorities signal greater effort on the development of rural communities. The purpose of the project described in this paper is to initiate, stimulate and follow up the development of five selected rural communities, to enhance our understanding of and knowledge about conditions which promote rural development, and test these conditions. The project has an action/advisory part and a research part. It is organized with local and central project workers, local boards and a central board. Project objectives include innovation/development, evaluation of the organization process, and research on the conditions for development. On basis of the results from the project, the following main themes are discussed: the effect of initiatives and incentives for rural development, connections between agriculture and other industries, typical income combining strategies/activities on farms, and how to stimulate innovation and the climate for entrepreneurial activity.

description: Agricultural Cooperatives constitute an important feature of the South African agriculture, especially in financing the sector. Because of the country's history of apartheid, the majority of the effective cooperatives were patronized by white commercial farmers to the exclusion of small-scale, black farmers. The objective of this paper is to strategically analyze agricultural cooperatives in South Africa, using the SWOT approach. The paper examines the need to face the challenge of change and suggests effective measures for refocusing agricultural cooperatives in South Africa. The implication of the status quo on the future of agricultural cooperatives and farming as a whole is analyzed. Suggestions are offered for restructuring and strengthening agricultural cooperatives in South Africa.

The Impact of Population Growth on Economic Growth: Evidence from Ethiopia
Creators: name: Mitiku, Amare
Publisher: name: Abyssinia Journal of Business and Social Sciences
Year: 2021

description: Population growth and economic growth are highly interrelated since they affect each other. This paper examines the impact of population growth on economic growth in Ethiopia using annual time series data from 1980/81-2016/17. Results from unit root test shows that the series under consideration contains a mixture of stationary variables at level (I (0)) and stationary at first difference (I(1)) implying that the model to be followed must be Autoregressive Distributed Lag model and the diagnostic tests executed on the model shows that the model is correctly specified having normally distributed residual as well there is no evidence of autocorrelation and heteroskedasticity. Result from Autoregressive Distributed Lag model or Bounds testing indicates that there exists a sustainable long-run relationship (co-integration) between population growth and Economic growth. The coefficient of the estimated error correction term is found to be - 0.931244 and highly significant further confirming the existence of long run relationship and implying that it only takes one year and about a month for the short run disequilibrium to adjust towards the long run equilibrium. The empirical model reveals that population growth has significant positive impact on the economic growth both in the short-run and long-run. Moreover, Toda-Yamamoto and Dolado-Lutkepohi as well as Innovative Accounting Techniques approach to Granger causality analysis shows that there exist bidirectional causality between population growth and economic growth which is witnessed to be strong by impulse responses and variance decompositions. The implication of the findings is that population is an asset rather than a burden for Ethiopia, and therefore a carefully planned population expansion along with sustainable economic growth, better employment opportunities and expanded quality education given the equality and justice in social, political and economic spheres would drive the economic growth and development in the country.

description: Fast Repetition Rate fluorometry (FRRf) generates high-resolution measures of phytoplankton primary productivity as electron transport rates (ETRs). How ETRs scale to corresponding inorganic carbon (C) uptake rates (the so-called electron requirement for carbon fixation, e,C), inherently describes the extent and effectiveness with which absorbed light energy drives C-fixation. However, it remains unclear whether and how e,C follows predictable patterns for oceanographic datasets spanning physically dynamic, and complex, environmental gradients. We utilise a unique high-throughput approach, coupling ETRs and 14C-incubations to produce a semi-continuous dataset of e,C (n = 80), predominantly from surface waters, along the Australian coast (Brisbane to the Tasman Sea), including the East Australian Current (EAC). Environmental conditions along this transect could be generally grouped into cooler, more nutrient-rich waters dominated by larger size-fractionated Chl-a (>10 um) versus warmer nutrient-poorer waters dominated by smaller size-fractionated Chl-a (< 2 um). Whilst e,C was higher for warmer water samples, environmental conditions alone explained less than 20% variance of e,C, and changes in predominant size-fraction(s) distributions of Chl-a (biomass) failed to explain variance of e,C. Instead, NPQNSV was a better predictor of e,C, explaining 55% of observed variability. NPQNSV is a physiological descriptor that accounts for changes in both long-term driven acclimation in non-radiative decay, and quasi-instantaneous PSII downregulation, and thus may prove a useful predictor of e,C across physically-dynamic regimes, provided the slope describing their relationship is predictable.

Year: 2018

description: Micro and Small Enterprises (MSEs) are expected to acquire business knowledge, skills and expertise to profitably operate their business consistently in this contemporary business dynamics. The current study aims to examine the perceived entrepreneurial capabilities of MSEs in the selected town of the south Wollo Zone, Ethiopia. Entrepreneurial capability related data were collected from 78 randomly selected MSEs owner/managers and data were collected through a 5-point Likert scale questionnaire. The mean significant test and correlation results of the study indicated that significant number of MSEs acquired the basic entrepreneurial capabilities (like goal setting, commitment and persistence, information seeking, and opportunity hunting) to run their business. The ranked mean and paired-sample t test result indicated that there is a significant difference on the possession of different entrepreneurial capabilities by MSEs. MSE capability of maintaining the goodwill of their organization is better possessed by MSEs than other entrepreneurial capabilities. Furthermore, MSEs with one entrepreneurial capability are more likely to have other capabilities too. Future researches shall determine the relationship of perceived entrepreneurial capabilities with MSEs’ performance.

description: Understanding the heating of electrons to quasi-thermal energies at collisionless shocks has broad implications for plasma astrophysics. It directly impacts the interpretation of X-ray spectra from shocks, is important for understanding how energy is partitioned between the thermal and cosmic ray populations, and provides insight into the structure of the shock itself. In Ghavamian, Laming & Rakowski (2007) we presented observational evidence for an inverse square relation between the electron-to-proton temperature ratio and the shock speed at the outer blast waves of supernova remnants in partially neutral interstellar gas. There we outlined how lower hybrid waves generated in the cosmic ray precursor could produce such a relationship by heating the electrons to a common temperature independent of both shock speed and the strength of the ambient magnetic field. Here we explore the mechanism of lower hybrid wave heating of electrons in more detail. Specifically we examine the growth rate of the lower hybrid waves for both the kinetic (resonant) and reactive cases. We find that only the kinetic case exhibits a growing mode. At low Alfvén Mach numbers (~15) the growth of lower hybrid waves can be faster than the magnetic field amplification by modified Alfvén waves.

description: Fermi--Löwdin orbitals (FLO) are a special set of localized orbitals, which have become commonly used in combination with the Perdew--Zunger self-interaction correction (SIC) in the FLO-SIC method. The FLOs are obtained for a set of occupied orbitals by specifying a classical position for each electron. These positions are known as Fermi-orbital descriptors (FODs), and they have a clear relation to chemical bonding. In this study, we show how FLOs and FODs can be used to initialize, interpret and justify SIC solutions in a common chemical picture, both within FLO-SIC and in traditional variational SIC, and to locate distinct local minima in either of these approaches. We demonstrate that FLOs based on Lewis' theory lead to symmetry breaking for benzene -- the electron density is found to break symmetry already at the symmetric molecular structure -- while ones from Linnett's double-quartet theory reproduce symmetric electron densities and molecular geometries. Introducing a benchmark set of 16 planar, cyclic molecules, we show that using Lewis' theory as the starting point can lead to artifactual dipole moments of up to 1 Debye, while Linnett SIC dipole moments are in better agreement with experimental values. We suggest using the dipole moment as a diagnostic of symmetry breaking in SIC and monitoring it in all SIC calculations. We show that Linnett structures can often be seen as superpositions of Lewis structures and propose Linnett structures as a simple way to describe aromatic systems in SIC with reduced symmetry breaking. The role of hovering FODs is also briefly discussed.

description: Indicators for sustainable agriculture developed in New Zealand to date have focused more on the environmental and biophysical than the social and financial components. The latter, however, are increasingly seen as pre-requisites to achieving long term financial and social viability in the agricultural sector. At present environmental costs are internalised in the financial performance of farmers because environmental protection in agriculture is funded almost entirely by farmers. It is therefore necessary to examine the perception of farmers on whether a relationship exists between farm financial resources and the environmental effects of farming to identify pragmatic and reliable financial indicators of sustainable agriculture at both the farm and the regional or national level. This paper examines the links between financial, social and environmental indicators to better understand if cause and effect relationships exist between them and introduces a range of economic indicators used to measure the financial health of a business. A model to evaluate the indicators in terms of their ability to measure the sustainability of farming businesses over time is described and performance indicators that could assist farmers to achieve sustainable farming goals are suggested.

Tonal voice-leading in Schoenberg’s opus 15
Creators: name: McNab, Grace A. L.
Publisher: name: University of British Columbia
Year: 2010

description: This study deals with the processes of tonal counterpoint inherent in the songs of Schoenberg's Opus 15i "Book of the Hanging Gardens" and, by implication, in related works. Chapter I, "The Concept of Harmonic Voice", introduces the conceptual key to the manner of investigation presented herein. Simply stated, "harmonic voices" consist of the strongly-directed, predictable motions by semitone and whole-tone, and the common-tone connections which occur from one chord to the next in a tonal progression. Examples of strongly-directed motions are the rising of the leading-tone and falling of the minor seventh of a dominant-seventh chord, and the diverging motions present when an augmented sixth progresses to an octave on the dominant. To show how the harmonic voice concept may be applied in analysis, passages from Opus 6, Number k are examined. Chapter II, "Harmonic Procedures Which Minimize Diatonic-Chromatic Differences", deals with specific types of harmonic voice motion which are common to chromatic passages and simpler, more overtly tonal ones. The lack of importance which the harmonic voice concept attributes to the presence or absence of the root of a chord is emphasized. The harmonic procedures discussed come under the following subject headings: "The Tritone-Substitute", "The Minor-Seventh/Augmented-Sixth Potential of 'Whole-tone' Chords", "Double-Neighbor Pairs in 'Whole-tone' and Other Contexts", "The Minor-Third Relationship", and "The Minor-Second Relationship". Passages from songs of Opus 3i 6, 12, and 14 are analyzed. Chapter III is a detailed analysis of Opus 1$, Number 5$ which applies the harmonic voice concept and attempts to expose the harmonic devices dealt with in Chapter II. Chapter IV is a detailed analysis of Opus 15, Number 11.

title: Social perceptions of men’s dominance and variations in men’s intrasexual competitiveness

description: Dominance plays a central role in human social interaction. Over the years, researchers have learned a lot about how men’s dominance is perceived by others, including that people use a variety of perceptual cues when judging men’s dominance and that these judgements are typically consistent across observers. However, questions remain concerning what external factors can influence a person’s perceptions of other’s dominance, and what factors affect individual differences in dominance and competitiveness. This thesis will review the current literature on dominance in men, before presenting three empirical chapters aimed at addressing gaps in the current literature. The first empirical chapter investigates the effects of testosterone and cortisol, on male intrasexual competitiveness, a key dominance behaviour. The study uses a longitudinal design to examine natural fluctuations in hormone levels over time. The study found no evidence of either a within-subject or between subject effect of testosterone, cortisol or their interaction, on intrasexual competitiveness. The second empirical chapter investigated regional variation in sensitivity to cues of dominance across US states. Despite strong theoretical predictions, the results show no compelling evidence that regional variation in population sex ratio influence sensitivity to cues of dominance. The final empirical chapter investigated the influence of transient cues, specifically head orientation on perceptions of dominance and trustworthiness. The results show that while tilting one’s head down does reliably increase perceptions of dominance and decrease perceptions of trustworthiness, it appears that cue does not have downstream context contingent effects for leadership judgements.
