Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The standard electroweak model is extended by means of a second Brout-Englert-Higgs-doublet. The symmetry breaking potential is chosen is such a way that (i) the Lagrangian possesses a custodial symmetry, (ii) a static, spherically symmetric ansatz of the bosonic fields consistently reduces the Euler-Lagrange equations to a set of differential equations. The potential involves, in particular, products of fields of the two doublets, with a coupling constant $λ_3$.Static, finite energy solutions of the classical equations are constructed. The regular, non-trivial solutions having the lowest classical energy can be of two types: sphaleron or bisphaleron, according to the coupling constants. A special emphasis is put to the bifurcation between these two types of solutions which is analyzed in function of the different constants of the model,namely of $λ_3$.

description: A homogeneous set of $n$ points in the $d$-dimensional Euclidean space determines at least $Ω(n^{2d/(d^2+1)} / \log^{c(d)} n)$ distinct distances for a constant $c(d)>0$. In three-space, we slightly improve our general bound and show that a homogeneous set of $n$ points determines at least $Ω(n^{.6091})$ distinct distances.

description: The objective of this work is to augment the basic abilities of a robot by learning to use sensorimotor primitives to solve complex long-horizon manipulation problems. This requires flexible generative planning that can combine primitive abilities in novel combinations and thus generalize across a wide variety of problems. In order to plan with primitive actions, we must have models of the actions: under what circumstances will executing this primitive successfully achieve some particular effect in the world? We use, and develop novel improvements on, state-of-the-art methods for active learning and sampling. We use Gaussian process methods for learning the constraints on skill effectiveness from small numbers of expensive-to-collect training examples. Additionally, we develop efficient adaptive sampling methods for generating a comprehensive and diverse sequence of continuous candidate control parameter values (such as pouring waypoints for a cup) during planning. These values become end-effector goals for traditional motion planners that then solve for a full robot motion that performs the skill. By using learning and planning methods in conjunction, we take advantage of the strengths of each and plan for a wide variety of complex dynamic manipulation tasks. We demonstrate our approach in an integrated system, combining traditional robotics primitives with our newly learned models using an efficient robot task and motion planner. We evaluate our approach both in simulation and in the real world through measuring the quality of the selected primitive actions. Finally, we apply our integrated system to a variety of long-horizon simulated and real-world manipulation problems.

description: Studies of the rotation-activity relation of late-type stars are essential to enhance our understanding of stellar dynamos and angular momentum evolution. We study the rotation-activity relation with K2 for M dwarfs where it is especially poorly understood. We analyzed the light curves of all bright and nearby M dwarfs form the Superblink proper motion catalog that were in the K2 field of view. For a sample of 430 M dwarfs observed in campaigns C0-C19 in long cadence mode we determined the rotation period and a wealth of activity diagnostics. Our study of the rotation-activity relation based on photometric activity indicators confirmed the previously published abrupt change of the activity level at a rotation period of ~10d. Our more than three times larger sample increases the statistical significance of this finding.

Fruit and vegetable intake and factors influencing intake of adolescents : developing the questionnaires
Creators: name: Li, Liming
Publisher: name: University of British Columbia
Year: 2009

description: Studies have suggested that fruit and vegetable intake might reduce the risk of cancer, cardiovascular disease, and other chronic diseases. Adolescents' fruit and vegetable intake appears to be below the recommended level according to Canada's Food Guide to Healthy Eating. There are many factors that may influence adolescents' fruit and vegetable intake. The objectives of this study were to develop a food frequency questionnaire (FFQ) to assess adolescents' fruit and vegetable intake, to develop an Attitude/Behaviour questionnaire looking at factors influencing their consumption of these foods and to test the validity and reliability of these 2 questionnaires. Students in grades 7 through 12 from 4 secondary schools were asked to participate in this study. The statements in the Attitude/Behaviour questionnaire were generated based on the literature and 3 focus group discussions with a total of 26 students. The FFQ was adapted from an existing questionnaire developed by the National Cancer Institute and was used to assess the fruit and vegetable intake over the previous 1 week. The FFQ was validated with a group of 63 students who completed the FFQ as well as a written 24-hour dietary record. The internal consistency reliability of the Attitude/Behaviour questionnaire and the face validity of the FFQ and the Attitude/Behaviour questionnaire were assessed with a group of 48 students. The test-retest reliabilities of these 2 questionnaires were tested with a group of 43 students who completed questionnaires on 2 occasions approximately 2 months apart. The correlation coefficient of the FFQ against the 24-hour dietary record was 0.52 and the test-retest reliability coefficient was 0.46. The internal consistency reliability of the Attitude/Behaviour questionnaire was 0.71 and the test-retest reliability was 0.59. Questionnaires were revised based on comments obtained from the face validity test. These results suggest that our developed questionnaires could be further used as research tools for the target group.

description: This article outlines the efforts of a small NGO, the Mareeba Wetland Foundation, to conserve nature and conduct tourism at its Mareeba Tropical Savanna Wetland Reserve in northern Queensland. It provides background about the establishment of the reserve and its nature and draws on the results from a survey of visitors to this reserve. It provides a socio-economic profile of visitors, their frequency of visits to it and their knowledge of it prior to visiting. This knowledge is found, on the whole, to be poor. The way in which visitors decided to visit the reserve is also considered as are indicators of the economic surplus obtained from visits. Because for most visitors their visit was an experiential good, doubts are raised about the traditional method of estimating the visitors’ surplus in these circumstances and also about the applicability of the travel cost method to estimating the demand for visits. A further difficulty noted (in relation to the applicability of the travel cost method) was the high frequency of multiple purpose journeys. The extent to which visitors learned about nature and nature conservation and obtained information about the Mareeba Wetland Foundation and its programmes is also evaluated. Views were solicited from respondents about the role which they believe NGOs should play in nature conservation and about public versus private provision of facilities and services in national parks. Significant implications are drawn about political failures in catering for nature conservation. Doubts are raised about the purist view that ecotourism needs to be conducted under virtually natural conditions if it is to make an optimal contribution to the conservation of biodiversity.

description: We study variability of active galactic nuclei (AGNs) by using the deep optical multiband photometry data obtained from the Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) survey in the COSMOS field. The images analyzed here were taken with 8, 10, 13, and 15 epochs over three years in the $g$, $r$, $i$, and $z$ bands, respectively. We identified 491 robust variable AGN candidates, down to $i=25$ mag and with redshift up to $4.26$. Ninety percent of the variability-selected AGNs are individually identified with the X-ray sources detected in the Chandra COSMOS Legacy survey. We investigate their properties in variability by using structure function analysis and find that the structure function for low-luminosity AGNs ($L_{\mathrm{bol}}\lesssim10^{45}$ erg s$^{-1}$) shows a positive correlation with luminosity, which is the opposite trend for the luminous quasars. This trend is likely to be caused by larger contribution of the host galaxy light for lower-luminosity AGNs. Using the model templates of galaxy spectra, we evaluate the amount of host galaxy contribution to the structure function analysis and find that dominance of the young stellar population is needed to explain the observed luminosity dependence. This suggests that low-luminosity AGNs at $0.8\lesssim z\lesssim1.8$ are predominantly hosted in star-forming galaxies. The X-ray stacking analysis reveals the significant emission from the individually X-ray undetected AGNs in our variability-selected sample. The stacked samples show very large hardness ratios in their stacked X-ray spectrum, which suggests that these optically variable sources have large soft X-ray absorption by dust-free gas.

description: This essay classifies different types of wildlife tourism on the basis of whether they rely on captive or non-captive wildlife and whether they involve consumptive or non-consumptive use of wildlife. It is argued that depending upon how they are managed, all these forms of wildlife tourism can be supportive of the conservation of wildlife. Different mechanisms for sharing the benefits of wildlife tourism are considered and it is argued that from several different perspectives, there can be too much or too little sharing of the economic benefits from wildlife tourism. Diverse stakeholders with an interest in wildlife tourism are identified and different ways (direct and indirect) in which they can benefit from wildlife tourism are specified. The distribution of these benefits plays an important role in facilitating access to wildlife resources for tourism purposes and in ensuring their conservation. However, it cannot be assumed that wildlife tourism operators have a large amount of profit or economic surplus to share. Factors that influence their level of profit are identified and discussed. Ways are considered in which the benefits from wildlife tourism might be increased in Australia. These include easier and more widespread access of tour operators to Australia’s wildlife resources held in the public domain and by some NGOs.

description: We present a general theory for the full counting statistics of multiple Andreev reflections in incoherent superconducting-normal-superconducting contacts. The theory, based on a stochastic path integral approach, is applied to a superconductor-double barrier system. It is found that all cumulants of the current show a pronounced subharmonic gap structure at voltages $V=2Δ/en$. For low voltages $V\llΔ/e$, the counting statistics results from diffusion of multiple charges in energy space, giving the $p$th cumulant $ \propto V^{2-p}$, diverging for $p\geq 3$. We show that this low-voltage result holds for a large class of incoherent superconducting-normal-superconducting contacts.

description: Since 1992, the European Union protects names of regional foods as Protected Designation of Origin (PDO) or Protected Geographical Indication (PGI). Besides direct benefits such as higher prices or the protection from unfair competition, researchers and rural development agents emphasize the indirect benefits resulting from an intensified interaction of producers, processers and retailers during the registration process. Based on a comparative case study in Austria, this paper analyses the relation of transaction costs and transaction benefits associated with the registration process of two PGIs. Whereas one case was based on extensive outsourcing to a private consultancy (for just under 50,000 Euro + 160 working hours invested by the producers over 3.5 years), the other one was mostly the result of extensive personal contributions of the regional producer group (2,000 hours over ten years) who were assisted by the state extension services (Chamber of Agriculture, additional 1,000 work hours). The comparative case study does not give any indication that outsourcing necessarily bears the risk of diminishing indirect benefits, such as social capital building, intensified co-operations with other rural sectors, higher awareness of and compliance with quality standards. This does not mean that there is no positive relation between transaction costs and transaction benefits but it emphasizes that there are more and less efficient processes.

description: Cross sectional scanning tunneling microscopy (XSTM) and density functional theory have been used to characterize the structure of GaSb digitally doped with Mn. The Mn dopants are found in both isolated substitutional form as well as in large clusters of zinc-blende MnSb commensurate with the surrounding GaSb matrix. Theoretical calculations predict that these two forms of Mn in the digitally doped layers will have a very different appearance in XSTM images. Substitutional Mn enhances the local density of states near the surface, thus appearing higher in a filled-state image. In contrast, MnSb clusters induce substantial structural relaxation at the {110} surface, and therefore appear as localized depressed regions with negligible perturbation of the surrounding GaSb.

description: When considering the Florida oranges as a local production system, two questions currently arise: is this system frightened by a globalization of the orange juice as a commodity whereas it is integrated to a globalized system? And is there any specific local asset remaining, such as a special quality and reputation which would justify a recognition as a geographical indication? Our findings demonstrate that there is a dilemma, for the State authorities as well as for some actors of the system, between an origin product approach and a sectorial commodity one.

description: In recent times, the search for a new relationship with nature, of quality and safety of foodstuffs and in particular the need for “identity”, of characterizing places as bearers of values and traditions have led an increasing number of people to see rural areas as places of values, resources, culture and products to discover and enjoy. Agriculture has taken on a multifunctional role and link with tourism is required to protect and exploit its “historical” resources (heritage) as a tool of interconnection between local products, countryside, traditions, cultural values but also to place emphasis of the territory and communicate it. The aim of paper is the role assumed today by firms regarding both the primary activity and other services, in particular those that express and support rural tourism. The objective is to assess the relationship between the company image, the entrepreneurial behavior built according to values, “typical” signs, historical resources of the rural world and the spin-offs on the territory. The research will be carried out by making specific reference to Calabria, a representative region of the Mediterranean area. Here, case-studies will be considered in sample areas where tourism and agriculture are integrated, with specific reference to vineyards and wine-making firms, is part of specific rural development strategies and initiatives. Therefore, we intend to highlight the important role of heritage and heritage marketing in order to privilege the competitive advantage that it can have for the company. The finding suggest the utility for rural tourism development: the heritage, which is often well preserved in rural areas is a valuable resource to integrate with management providing useful help as a vehicle for economic benefits also for a territory.
Magnetic properties of the overdoped superconductor La$_{2-x}$Sr$_{x}$CuO$_{4}$ with and without Zn impurities

description: The magnetic properties of the Zn-substituted overdoped high-$T_c$ superconductor La$_{2-x}$Sr$_{x}$Cu$_{1-y}$Zn$_{y}$O$_{4}$ have been studied by magnetization measurements and neutron scattering. Magnetization measurements reveal that for Zn-free samples with $x \geq 0.22$ a Curie term is induced in the temperature dependence of the magnetic susceptibility implying the existence of local paramagnetic moments. The induced Curie constant corresponds to a moment of 0.5 $μ_B$ per additional Sr$^{2+}$ ion that exceeds $x=0.22$. Zn-substitution in the overdoped \lsco also induces a Curie term that corresponds to 1.2 $μ_B$ per Zn$^{2+}$ ion, simultaneously suppressing $T_c$. The relationship between $T_c$ and the magnitude of the Curie term for Zn-free \lsco with $x \geq 0.22$ and for Zn-substituted \lsco with $x = 0.22$ are closely similar. This signifies a general competitive relationship between the superconductivity and the induced paramagnetic moment. Neutron scattering measurements show that Zn-substitution in overdoped \lsco anomalously enhances the inelastic magnetic scattering spectra around the $(π, π)$ position, peaking at $ω\sim 7$ meV. These facts are discussed on the basis of a "swiss-cheese" model of Zn-substituted systems as well as a microscopic phase separation scenario in the overdoped region indicated by muon-spin-relaxation measurements.

description: This paper investigates the strategies adopted by economic actors in the context of an institutional change. We base ourselves on data collected as part of an exploratory study in the sugar and fresh vegetable supply chains in Mauritius. The reform of the sugar protocol between the European Union and the ACP countries has given rise to two major consequences in the Mauritian agricultural sector. Firstly it has caused an institutional change in the sugar supply chain resulting in large sugar producers diversifying into other more remunerative economic sectors. We refer to research by North to analyse the indirect effects of the reform of the sugar protocol on another supply chain, the fresh vegetables supply chain. The second consequence refers to a second institutional change caused by the entry of large sugar cane producers on the fresh vegetable market. We refer to the theory on collective strategy to analyse whether it is an appropriate strategy for traditional vegetable producers to be more competitive. We conclude by saying that this exploratory study has allowed us to better understand the effects of the reform of the sugar protocol on the fresh vegetables supply chain. Incentives from public policies, entry of large sugar cane producers on the market, emergence of institutional entrepreneurs both among traditional actors of the supply chain and new entrants can lead to a deinstitutionalisation of the vegetable supply chain and eventually giving rise to new institutions with new rules of the game.

description: Excerpts from the report Summary: The 1966 amendments make Public Law 480 a more flexible instrument than previous P.L. 480 legislation for expanding export markets for U.S. farm commodities, and for fostering agricultural and total economic development and improving health and nutrition in the developing countries of the world. Under the new Act, developing nations will be required to demonstrate an adequate degree of self-help in agricultural development to be eligible for continued food assistance from the United States. They will have to show that steps are being taken to more rapidly increase per capita food and fiber production and to improve their storage and marketing facilities for agricultural products. The emphasis on self-help is designed to insure the effectiveness of food and other forms of assistance in achieving a better rate of economic progress in friendly developing countries.
Complete complementarity relations and its Lorentz invariance

description: It is well known that entanglement under Lorentz boosts is highly dependent on the boost scenario in question. For single particle states, a spin-momentum product state can be transformed into an entangled state. However, entanglement is just one of the aspects that completely characterizes a quantum system. The other two are known as the wave-particle duality. Although the entanglement entropy does not remain invariant under Lorentz boosts, and neither do the measures of predictability and coherence, we show here that these three measures taken together, in a complete complementarity relation (CCR), are Lorentz invariant. Peres et al., in [Phys. Rev. Lett. 88, 230402 (2002)], realized that even though it is possible to formally define spin in any Lorentz frame, there is no relationship between the observable expectation values in different Lorentz frames. Analogously, even though it is possible to formally define complementarity in any Lorentz frame, in principle, there's no relationship between the complementarity relations of different Lorentz frames. However, our result shows that it's possible to connect complete complementarity relations in different Lorentz frames. In addition, we explore relativistic scenarios for single and two particle states, which helps in understanding the exchange of different aspects of a quantum system under Lorentz boosts.

description: The establishment of Geographical Indications (GI) can be considered like an instrument, that from initiative of public policies of rural development, can have application for the protection of territorial agri-food productions that present tipicity. In the case of being Local Agri-food Systems (LAFS) with a little level of productive organization, the GI Regulatory Board can be considered like a key local institution, from which programs directed to the structuring of the sector are undertaken, affecting the professionalization and building social capital between the agents who compose the LAFS. In this case the Regulatory Board will assume a determining role in the transmission of knowledge and innovations in the LAFS.
Shear-melting of a hexagonal columnar crystal by proliferation of dislocations

description: A hexagonal columnar crystal undergoes a shear-melting transition above a critical shear rate or stress. We combine the analysis of the shear-thinning regime below the melting with that of synchrotron X-ray scattering data under shear and propose the melting to be due to a proliferation of dislocations, whose density is determined by both techniques to vary as a power law of the shear rate with a 2/3 exponent, as expected for a creep model of crystalline solids. Moreover, our data suggest the existence under shear of a line hexatic phase, between the columnar crystal and the liquid phase.

description: El presente trabajo tiene como objetivo abordar la discusión de uno de los enfoques alternativos que ha cobrado interés y vigencia entre los círculos de investigación vinculados al desarrollo rural, el de los Sistemas Agroalimentarios Locales (SIAL), que conjunta diversos planteamientos teóricos previos, como el de las economías derivadas de la localización de la industria, los Distritos Industriales (DI) o clusters, los Sistemas Productivos Locales (SPL) y la Agroindustria Rural (AIR), y que con el transcurso de los años, se le han ido agregando otros factores y conceptos que enriquecen el análisis del enfoque, entre los que destacan: la importancia cultural, la visión del territorio como espacio de proximidades, la activación de recursos específicos, la acción colectiva, la gobernanza territorial, la conformación de capital social y el desempeño institucional, entre otros. De lo anterior, en este trabajo, se abordan tres características de los SIAL: el papel del territorio o reconfiguración territorial, la acción colectiva y la conformación de capital social. Tomando en cuenta estas concepciones teóricas, en este documento, se intentará contrastarlas con el funcionamiento y desempeño de las redes sociales territoriales e institucionales en un municipio de México, denominado Tlalnepantla, que se encuentra ubicado en el estado de Morelos. En este municipio se ha desarrollado un cambio agro alimentario en el transcurso de 20 años, basado fundamentalmente en la producción de nopal (Opuntia o Nopalea) y en la conformación de sociedades de producción rural que les ha permitido ingresar a mercados internacionales y consolidarse como uno de los sitios de producción de nopal más importante de la zona centro del país. Mediante la realización del trabajo de campo se ha permitido recabar elementos que muestran que el reordenamiento productivo, basado en la producción de nopal, y en los cambios del paisaje, existen elementos muy importantes que enmarcan a la acción colectiva como el elemento clave que les ha permitido, a los pobladores de la comunidad, defender su identidad y extender su mercado.

description: In this paper we present results from numerical calculations for three identical boson systems for both very large and infinite two-body s-wave scattering length $a$. We have considered scattering lengths up to $2\times 10^5$ a.u. and solved the hyperangular part of the Schrödinger equation for distances up to $10^6$ a.u.. Form these, we obtained the three-body effective potentials, hyperspherical channel functions and the asymptotic behavior of the nonadiabatic couplings in order to to characterize the main aspects of the Efimov states. These results allow us to test and quantify the assumptions related to the Efimov effect.

description: Ante el abandono del campo mexicano de parte de sus pobladores, resultado del proceso de apertura comercial que ha conocido el país desde hace treinta años, y que se ha traducido en empobrecimiento y migración de los campesinos, resulta importante buscar alternativas. Volver a valorar productos tradicionales, enraizados en las culturas locales, con una fuerte carga de identidad y buscar la activación de un desarrollo local en torno a estos productos mediante actividades no solamente agrícolas sino también turísticas es una opción para algunas comunidades. El caso de una sal de origen prehispánico, cuyos usos han sido no solamente alimentarios sino curativos, ofrece estas posibilidades. La Ruta de la Sal, en Zapotitlán de las Salinas, Puebla, es un proyecto en ejecución que incorpora planteamientos de desarrollo local relativamente nuevos para el contexto rural mexicano. Su forma de operación es través del modelo de rutas alimentarias, basadas en la integración de un alimento con fuerte identidad local como elemento focal del producto turístico. En este lugar, destaca el desarraigo, relativamente alto, de la población masculina de su contexto rural originario. Mediante un diagnóstico participativo, se determinó a la sal como el producto más característico y al turismo como una actividad factible para mujeres, niños y jóvenes que habitan en la comunidad. El presente trabajo establece la relación entre turismo rural, alimentos con identidad y desarrollo local para lo cual se plantearon los siguientes objetivos: identificar los factores determinantes para la implementación del proyecto de la Ruta de la Sal; identificar los agentes locales y externos, las instituciones públicas, privadas o no gubernamentales que pueden construir sinergias para la realización del proyecto; analizar las redes de cooperación o de conflicto que lo afectan, en un sentido u otro. Particularmente, evaluar la participación de los actores locales tanto en el proyecto como en sus beneficios.
Dancing with the Dance of the Dead : cemetery of the Innocents and the ramifications of the Macabre
Creators: name: Dujakovic, Maja
Publisher: name: University of British Columbia

description: The following thesis discusses the very first depiction of the "Danse Macabre" (Dance of the Dead) at the Paris cemetery of the Holy Innocents. The mural, now known only through prints and literary descriptions, was painted in 1424-5 on the cloister wall of this prominent medieval burial ground, and depicted fifteen pairs of dancing partners arranged according to their station in late medieval secular or ecclesiastic society. The pairs, composed of one dead and one living partner, are framed by a scholarly figure, known as the Author, who introduces and concludes the dance. The mural was accompanied by written verses - a captivating and often humorous dialogue between the living and the dead - which were placed below each figure, further animating the image. Many medievalists have recognized the significance and influence of this first visual rendition of the "Danse Macabre", as its verses and composition, although often modified, served as a model for many fifteenth century illustrations of the Dance of the Dead not just in France, but elsewhere in Western Europe. While it is probably true that the taste for the macabre within a broader public must in some way have been conditioned by the calamitous events of the fourteenth and fifteenth centuries, I argue that are very particular historical conditions that produced the "Danse Macabre" in Paris. Specifically, the first two decades of the fifteenth century were characterized by a renewed war with England and a series of assassinations and counter-assassinations of pretenders for the French Crown. I argue that the mural, whose verse originated in the theological circles of the University of Paris, had a twofold didactic purpose: on the one hand the mural emphasized the transitory nature of earthly life and promoted the religious message of piety and repentance by evoking a horrid image of the decomposing cadaver, and on the other it functioned as a social critique. Employing the language of allegory, the University, itself profoundly invested in the political situation of the time, used the "Danse Macabre", with its theme of death as the ultimate equalizer to contest the political machinations over kingship and establish its own position as society's dominant rationalizing authority.

description: Over the past three decades the development of agricultural research staff in sub- Saharan Africa has been impressive. There were significant increases in the number of researchers (a sixfold increase if South Africa is excluded), in Africanization (from about 90 percent expatriates in 1961 to 11 percent in 1991), and in education levels (over 60 percent of national researchers held a postgraduate degree in 1991). Developments in agricultural research expenditures were less positive. After reasonable growth in spending throughout much of Africa in the 1960s and early 1970s, growth largely stopped in the late 1970s. Donors have been dominant and increasing sources of support for agricultural research in Africa; their share of total agricultural R&D funding (excluding South Africa) grew from 34 percent in 1986 to 43 percent in 1991 -- 49 percent in 1991 if the large and largely locally funded Nigerian system is also excluded. Moreover, an analysis of government spending patterns provides evidence that many of the countries throughout Africa have shifted public investment priorities away from agricultural research. But these overall patterns of development mask important differences between countries and among institutions within countries and these differences have real policy consequences. Many of the developments of the past decade in personnel, expenditures, and sources of support for public-sector R&D in Africa are not sustainable. The rapid buildup of research staff is not paralleled by an equal growth in financial resources. Spending per scientist has continuously declined during the past 30 years, but most dramatically during the 1980s. Resources are spread increasingly thin over a growing group of researchers, which has negative effects on the efficiency and effectiveness of agricultural research.

description: Excerpts from the report Preface: There has been a continuous demand for a publication presenting a review of shipments under U.S. food aid programs for the period since the initiation of Public Law 83-480, the Trade Development and Assistance Act of 1954, as amended. This publication presents a statistical summary of shipments under programs authorized by P.L. 480 and Mutual Security (AID) programs for 12 fiscal years, 1955 through 1966. Exports are reported by commodity, value, and quantity, for each year of the 12-year period. They are also reported by commodities grouped by individual years. The value of exports by country is shown for each year and for the 12-year period. Exports under credit sales programs -- the Commodity Credit Corporation (CCC) export credit sales program and Export-Import Bank loans and guarantees -- are reported by commodity and by country. The extent of export payment assistance to commercial sales for dollars is briefly summarized. The text reviews the evolution of P.L. 480 programs through the most recent amendment, P.L. 89-808, effective January 1, 1967. Individual programs are summarized and some of the principal achievements noted.

description: We study lattice Hamiltonian realisations of (3+1)d Dijkgraaf-Witten theory with gapped boundaries. In addition to the bulk loop-like excitations, the Hamiltonian yields bulk dyonic string-like excitations that terminate at gapped boundaries. Using a tube algebra approach, we classify such excitations and derive the corresponding representation theory. Via a dimensional reduction argument, we relate this tube algebra to that describing (2+1)d boundary point-like excitations at interfaces between two gapped boundaries. Such point-like excitations are well known to be encoded into a bicategory of module categories over the input fusion category. Exploiting this correspondence, we define a bicategory that encodes the string-like excitations ending at gapped boundaries, showing that it is a sub-bicategory of the centre of the input bicategory of group-graded 2-vector spaces. In the process, we explain how gapped boundaries in (3+1)d can be labelled by so-called pseudo-algebra objects over this input bicategory.
