description: In order to reduce obesity and associated costs, policymakers are considering various policies, including taxes, to change consumers’ high-calorie consumption habits. We investigate two tax policies aimed at reducing added sweetener consumption. Both a consumption tax on sweet goods and a sweetener input tax can reach the same policy target of reducing added sweetener consumption. Both tax instruments are regressive, but the associated surplus losses are limited. The tax on sweetener inputs targets sweeteners directly and causes about five times less surplus loss than the final consumption tax. Previous analyses have overlooked this important point.

description: Rapid growth in urban populations and renewed growth in per capita incomes in Sub-Saharan Africa (SSA) are creating major opportunities for local farmers by driving rapid growth in domestic market demand for food. At the same time, these trends plus rising income are putting enormous stress on the supply chains that these farmers rely on to respond to this increasing demand: demand for marketed food is likely to grow more than 5% per year on the continent, doubling marketed volumes in 12-14 years. Currently, fresh produce marketing systems are the biggest users of public marketing infrastructure, and have been most severely affected by the lack of investment in these systems across much of the continent. This lack of investment has led to an exploding informal marketing sector, rising concerns about congestion and hygiene, and few if any comprehensive programs to actively link farmers to these markets.

description: Brokers are agents who arrange sales without taking ownership of the commodity, earning their money on a commission. Brokers are a common but often controversial presence in wholesale markets of East and Southern Africa. Efficient brokering can be beneficial by matching buyers and sellers more effectively than if each had to search independently for someone to transact with. Yet buyers and sellers can be harmed if brokers are able to behave in uncompetitive, collusive, or unethical ways. In Soweto market of Lusaka, common complaints lodged by sellers are that brokers force sellers to use them by threatening the security of the sellers’ produce, and that the brokers add “hidden” commissions when selling a farmer or trader’s produce. This policy brief explores the role of brokers in the marketing of fresh produce in Soweto Market. It concludes that, while brokers appear to provide some valued service to some sellers, the chaotic nature of the market and the lack of any regulatory and enforcement structure leads to questionable broker behaviour including charging of hidden commissions. As government and city officials grapple with how to improve fresh produce wholesaling, it is imperative that they focus not just on physical infrastructure but also on the governance, regulatory, and enforcement structures without which new market places will be of little use.

description: The uncertainty principle is a cornerstone of modern physics, and its implications have a fundamental impact on theoretical and applied quantum mechanics. The aim of this thesis is to study and apply the uncertainty relations between time and energy, which are interpreted operationally as the speed limit of quantum evolution. A geometric approach is used to derive improved bounds for the evolution of isolated and open systems and obtain a constructive approach for efficient and fast quantum driving. These results are applied to set the limits for the rate of information transfer and processing, and the power of nanomachines.

description: Key findings regarding the structure of trade for tomato, rape, and onion into Lusaka are (a) regional trade is an important part of Zambia’s fresh produce system, (b) supply chains for tomato, rape, and onion are short, (c) the role of the modern market system is very small, and (d) the role of urban agriculture in supplying Lusaka markets for these vegetables is also small, though it is meaningful in the case of rape. Main policy implications from this and related work are that (a) investments and policies to promote regional trade are relevant for the horticultural sector, not just food staples, (b) the traditional market system needs improved hard infrastructure linked to more collaborative public/private management models and improved coordination in the supply chains, and (c) more programmatic emphasis should be placed on helping existing traders scale-up and gain better access to information to do their job more effectively.

description: We present radio continuum observations of the planetary nebula (PN) IRAS 17347-3139 (one of the only two known to harbour water maser emission), made to derive its spectral index and the turnover frequency of the emission. The spectrum of the source rises in the whole frequency range sampled, from 2.4 to 24.9 GHz, although the spectral index seems to decrease at the highest frequencies (0.79+-0.04 between 4.3 and 8.9 GHz, and 0.64+-0.06 between 16.1 and 24.9 GHz). This suggests a turnover frequency around 20 GHz (which is unusual among PNe, whose radio emission usually becomes optically thin at frequencies < 10 GHz), and a relatively high emission measure (1.5 x 10^9 cm^{-6} pc). The radio continuum emission has increased by a factor of ~1.26 at 8.4 GHz in 13 years, which can be explained as expansion of the ionized region by a factor of ~1.12 in radius with a dynamical age of ~120 yr and at an expansion velocity of ~5-40 km/s. These radio continuum characteristics, together with the presence of water maser emission and a strong optical extinction suggest that IRAS 17347-3139 is one of the youngest PNe known, with a relatively massive progenitor star.

description: The results of computer simulation of the dynamics of fullerene C_20 at different temperatures are presented. It is shown that, although it is metastable, this isomer is very stable with respect to the transition to a lower energy configuration and retains its chemical structure under heating to very high temperatures, T ~ 3000 K. Its decay activation energy is found to be E_a ~ 7 eV. Possible decay channels are studied, and the height of the minimum potential barrier to decay is determined to be U = 5.0 eV. The results obtained make it possible to understand the reasons for the anomalous stability of fullerene C_20 under normal conditions.

description: While agriculture definitely is a traditional and important sector of national economy, it is also a sector the importance of which is often underestimated. More correct and realistic description of its economic role should be based on input-output methods. Unfortunately regional level input-output tables are only rarely available. We therefore apply modified GRIT regionalization methodology on a remote rural NUTS 2 level region in three different countries (Germany, Greece, and the Czech Republic respectively) and demonstrate that this approach makes regional-level input-output analysis a viable tool in realistic evaluation of contribution of the agri-food production chain for local economies. We provide empirical results that enable us to describe the importance of regional role of agriculture (both individually and in combination with down-stream sectors) more realistically. Our research based on application of regional level input-output methods clearly demonstrates that the importance of agri-food production chain especially for remote regions remains very high – even for heavily industrialized countries - and its demise would lead to dramatic structural shocks.

description: Increasing capacity demands in the access networks require inventive concepts for the transmission and distribution of digital as well as analog signals over the same network. Here a new transceiver system, which is completely agnostic for the signals to be transmitted is presented. Nyquist sampling and time multiplexing of N phase and intensity modulated digital and analog channels with one single modulator, as well as the transmission and demultiplexing with another modulator have been demonstrated. The aggregate symbol rate corresponds to the modulator bandwidth and can be further increased by a modification of the setup. No high-speed electronic signal processing or high bandwidth photonics is required. Apart from its simplicity and the possibility to process high bandwidth signals with low bandwidth electronics and photonics, the method has the potential to be easily integrated into any platform and thus, might be a solution for the increasing data rates in future access networks.

description: This paper addresses three issues of socio-economic factors of Hungarian farm households and their impacts on structural change. This concerns the role of age as a factor influencing the opportunity costs of labour, the impact of empirical age patterns on structural change, and the role of a varied probability of young farm successors entering into the farming business. Results of a farm household survey are integrated in simulation experiments with the agent-based model AgriPoliS which has been adapted to a Hungarian case study region. It could be shown that impediments of a flexible labour adjustment slow down structural change while the timing of persisting or exiting of farms highly depends on the age distribution of farmers.

description: This paper analyses expert attitudes to managing rural development in both established (EU15) and New Member States (NMS). It draws on case studies of five regions in the EU15 that have undergone, at least in some respects, successful rural development post-accession. Lessons of best practice were identified from interviews and supporting documentation, and verified / refined using a policy Delphi exercise. The results highlight the importance of creating appropriate national and regional structures to implement EU funded projects, capacity building, decentralisation, social capital and networking, and the role of “institutional memory”.

description: Innovation and new technology adoption represent two central elements for the enterprise and industry development process in agriculture. The objective of the paper is to provide an ex-ante analysis of the effectiveness of alternative policy design options concerning the RDP measures intended to provide incentives for investment/innovation adoption in five case study areas across Europe. The model implemented is based on a real option approach that includes investment irreversibility and stochasticity in SFP. The results show the relevance of uncertainty in determining the timing of adoption and emphasise the importance of predictability as a major component of policy design.

Diagnosis. Length: 5.40–8.50 mm; width: 3.80–6.00 mm. Form elongate oval, dorsum strongly convex and glabrous. A highly variably coloured and polymorphic species (Fig. 86), that can be reliably identified by the presence of a pair of conspicuous ridges / plicae, sometimes reduced in the apical third of elytra. Genitalia not studied.
Distribution. India (West Bengal); Nepal; China; Taiwan; Japan; Palaearctic; deliberately or accidentally introduced in many parts of Europe, North America, Central America, South America, Africa and New Zealand (Ślipiński et al. 2020).
Notes. This species, commonly known as Multicoloured Asian lady beetle or Harlequin ladybird, has become one of the major alien invasive species in several parts of the world and causes a great deal of nuisance. It has also been reported to reduce the abundance of native lady beetles in many countries, besides causing several other non-target effects (Koch 2003). A single specimen from Nepal (Fig. 86e, f) was examined for this study and it is presumed to be present in the unexplored parts of northwestern and eastern Himalayan region, a hotspot of diversity for Coccinellini and the states on the Indo-Chinese border.
It has been described and illustrated by many authors including Sasaji (1971), Kuznetsov (1997), Ren et al. (2009), Yu (2010) and Ślipiński et al. (2020). Sasaji (1981) carried out crossing experiments with the polymorphic forms. Koch (2003) reviewed its biology, use in biocontrol and non-target impacts. Numerous papers have been published in recent years about its invasive potential and not mentioned here.

description: Some properties of the Clifford algebras Cl(3,0), Cl(1,3), Cl(1,3)(C), Cl(4,1) and Cl(2,4) are presented, and three isomorphisms between the Dirac-Clifford algebra C x Cl(1,3) and Cl(4,1) are exhibited, in order to construct conformal maps and twistors, using the paravector model of spacetime. The isomorphism between the twistor space inner product isometry group SU(2,2) and the group Spin+(2,4) is also investigated, in the light of a suitable isomorphism between C x Cl(1,3) and Cl(4,1). After reviewing the conformal spacetime structure, conformal maps are described in Minkowski spacetime as the twisted adjoint representation of Spin+(2,4), acting on paravectors. Twistors are then presented via the paravector model of Clifford algebras and related to conformal maps in the Clifford algebra over the Lorentzian R(4,1) spacetime. We construct twistors in Minkowski spacetime as algebraic spinors associated with the Dirac-Clifford algebra C x Cl(1,3) using one lower spacetime dimension than standard Clifford algebra formulations, since for this purpose the Clifford algebra over R(4,1) is also used to describe conformal maps, instead of R(2,4). Our formalism sheds some new light on the use of the paravector model and generalizations.

description: The current study aims to examine the effectiveness of fisheries policies and specifically of the Greek Operational Programme for Fisheries, 2007-13. In specific, aims to examine and assess possible impacts generated, in the regional economy of Voreio and Notio Aigaio from its four axis, with particularity to the forth one. For this a regional Input-Output model was built in order to capture direct and indirect impacts in terms of output, employment and income. Results indicate that the dynamics of the fisheries sector in the regional economy are very weak and along with the continuous shrinking of the sector, leads to the necessity of supporting alternative vocational activities for the development of coastal rural areas. Though, results indicate that the funds attributed to such policies are very small, resulting in very weak generated impacts in the regional economy. And thus it is not expected current policies to seriously affect the development of such regions through the promotion of alternative to fishing activities.

However, a number of unexplored options are still available from the literature about policy analysis and biophysical systems representations. A particularly important need concerns the representation of the complexity of rural systems either in a static or dynamic framework In this paper we use Bayesian networks, to the best knowledge of the authors, basically ignored by the literature on rural development. The objective of this paper is to discuss the potential use of Bayesian Networks tools to represent the impact of the Common Agricultural Policies in rural areas.

description: We present the results of Monte Carlo simulations of the magnetic properties of individual spherical nanoparticles with the aim to explain the role played by surface anisotropy on their low temperature magnetization processes. Phase diagrams for the equilibrium configurations have been obtained, showing a change from quasi-uniform magnetization state to a state with hedgehog-like structures at the surface as $k_S$ increases. Through the simulated hysteresis loops and the analysis of spin configurations along them, we have identified a change in the magnetization reversal mechanism from quasi-uniform rotation at low $k_S$ values, to a non-uniform switching process at high $k_S$. Results for the dependence of the coercive field and remanence on $k_S$ and particle size are also reported.

description: This paper presents the results of a household survey designed to qualitatively evaluate the impacts of the invasive alien species Senna spectabilis on the distribution of welfare across dependent communities in Budongo forest reserve (BFR) in Uganda. BFR is the largest forest reserve in Uganda with globally significant conservation values. The study establishes that households in BFR have high levels of knowledge on its conservation values, they are aware of the invasiveness of S. spectabilis and its potential to compromise the conservation values of BFR, and that S. spectabilis confers tangible benefits to dependent households, whose levels significantly vary with proximity to the reserve. The study concludes by evaluating strategies designed to manage the spread of S. spectabilis in BFR which consider its demonstrated socioeconomic impacts.

description: An exactly solvable model for the rewiring dynamics of weighted, directed networks is introduced. Simulations indicate that the model exhibits two types of condensation: (i) a phase in which, for each node, a finite fraction of its total out-strength condenses onto a single link; (ii) a phase in which a finite fraction of the total weight in the system is directed into a single node. A virtue of the model is that its dynamics can be mapped onto those of a zero-range process with many species of interacting particles -- an exactly solvable model of particles hopping between the sites of a lattice. This mapping, which is described in detail, guides the analysis of the steady state of the network model and leads to theoretical predictions for the conditions under which the different types of condensation may be observed. A further advantage of the mapping is that, by exploiting what is known about exactly solvable generalisations of the zero-range process, one can infer a number of generalisations of the network model and dynamics which remain exactly solvable.

description: La présente étude a pour objectif une évaluation de l’état de pauvreté des riziculteurs du nord-Togo dans les zones d’introduction des NERICA en vue d’apprécier leurs capacités de résistance aux risques naturels et économiques. Pour parvenir à cette fin, des données primaires collectées sur la base d’une enquête effectuée auprès de 255 ménages dans 20 villages dans les régions centrale et de la Kara, ont été analysées par la méthode de FOSTER GREER et THORBECKE basée sur les dépenses de consommation. L’incidence, la profondeur et la sévérité, sont respectivement de 88,37%, 31% et 12,98%. Le niveau de pauvreté est pratiquement le même aussi bien chez les producteurs de NERICA que les producteurs des variétés. The present study’s objective is an evaluation of the state of poverty of the rice growers of north-Togo in the zones of introduction of the NERICA in order to assess their abilities of resistance to the natural and economic risks. To reach this objective, primary data on 255 households in 20 villages were collected at the central and Kara areas of Togo. These data were analyzed using FOSTER GREER and THORBECKE method based on the consumer expenditure. The incidence, the depth and severity of poverty are estimated to 88,37%, 31% and 12,98% respectively. Moreover, there is no significant difference between the level of poverty observed with NERICA producers and other producers.
"Literature absorbed through the skin" : intertextuality in Primo Levi’s If this is a man
Creators: name: Reynolds, Isla
Publisher: name: University of British Columbia

description: Despite Levi's claim that "reason, art, and poetry are no help in deciphering a place in which they are banned," literary references litter his memoirs which aim to elucidate and explain the experience of the concentration camp both for the reader and for Levi himself (DS 142). However, simple allegorical comparison does not result in this explanation; indeed Levi's use of literary referents tends to complicate rather than clarify his experience of the Lager. By using Dante's Divine Comedy as an intertext, Levi introduces a variety of possible, often antagonistic, interpretations of his own memoir. This coexistence of different readings allows Levi to avoid reducing the Lager to a single definitive signified, and therefore pre-empts any possibility of rationalizing the Holocaust in terms of literary or cultural tropes.This multiplicity also ultimately demonstrates the difficulties faced by any attempt, whether literary or otherwise, to represent a past experience, especially one that involves such atrocity. However, rather than submitting to the problems inherent to language, Levi is aware of the diversity of interpretations introduced through intertextuality and uses this multiplicity to attempt the difficult task of representing the Lager without reducing the horror or consequence of the experience. By illustrating the inadequacy of The Divine Comedy as a referent, Levi indicates the enormity of his experience without reducing it to a deficient linguistic description. The complex intertextual networks which produce the comparison between Dante and Levi also undermine it and in doing so demonstrate the ultimately impenetrable nature of the Lager as an actual event, while still delineating its presence and significance.

description: Using deep HST ACS imaging and VLT FORS2 spectra, we determined the velocity dispersions, effective radii and surface brightnesses for four early-type galaxies in the $z=1.237$ cluster \cl. All four galaxies are massive, $> 10^{11} M_{\sun}$. These four galaxies, combined with three from \lynx at $z=1.276$, establish the Fundamental Plane of massive early-type cluster galaxies at $\bar{z}=1.25$. The offset of the Fundamental Plane shows that the luminosity evolution in rest-frame $B$ is $Δ\ln M/L_B = (-0.98 \pm 0.06) z$ for galaxies with $M > 10^{11.5} M_{\sun}$. To reproduce the observed mass-to-light ratio ($M/L$) evolution, we determine the characteristic age of the stars in these $M > 10^{11.5} M_{\sun}$ galaxies to be $3.0^{+0.3}_{-0.3}$ Gyrs, {\em i.e.} $z_{*}=3.4^{+0.5}_{-0.4}$. Including selection effects caused by morphological bias (the ``progenitor bias''), we estimate an age of $2.1^{+0.2}_{-0.2}$ Gyrs, or $z_{*} = 2.3^{+0.2}_{-0.2}$ for the elliptical galaxy population. Massive cluster early-type galaxies appear to have a large fraction of stars that formed early in the history of the universe. However, there is a large scatter in the derived $M/L$ values, which is confirmed by the spread in the galaxies' colors. Two lower mass galaxies in our $\bar{z}=1.25$ sample have much lower $M/L$ values, implying significant star-formation close to the epoch of observation. Thus, even in the centers of massive clusters, there appears to have been significant star formation in some massive, $M \simeq 10^{11} M_{\sun}$, galaxies at $z\simeq 1.5$.

Gas Kinematics of the Massive Protocluster G286.21+0.17 Revealed by ALMA

description: We study the gas kinematics and dynamics of the massive protocluster G286.21+0.17 with the Atacama Large Millimeter/submillimeter Array using spectral lines of $C^{18}O$(2-1), $N_2D^+$(3-2), $DCO^+$(3-2) and $DCN$(3-2). On the parsec clump scale, $C^{18}O$ emission appears highly filamentary around the systemic velocity. $N_2D^+$ and $DCO^+$ are more closely associated with the dust continuum. $DCN$ is strongly concentrated towards the protocluster center, where no or only weak detection is seen for $N_2D^+$ and $DCO^+$, possibly due to this region being at a relatively evolved evolutionary stage. Spectra of 76 continuum defined dense cores, typically a few 1000 AU in size, are analysed to measure their centroid velocities and internal velocity dispersions. There are no statistically significant velocity offsets of the cores among the different dense gas tracers. Furthermore, the majority (71\%) of the dense cores have subthermal velocity offsets with respect to their surrounding, lower density $C^{18}O$ emitting gas. Within the uncertainties, the dense cores in G286 show internal kinematics that are consistent with being in virial equilibrium. On clumps scales, the core to core velocity dispersion is also similar to that required for virial equilibrium in the protocluster potential. However, the distribution in velocity of the cores is largely composed of two spatially distinct groups, which indicates that the dense molecular gas has not yet relaxed to virial equilibrium, perhaps due to there being recent/continuous infall into the system.

Lithium Ionization by a Strong Laser Field

description: We study ab initio computations of the interaction of Lithium with a strong laser field. Numerical solutions of the time-dependent fully-correlated three-particle Schroedinger equation restricted to the one-dimensional soft-core approximation are presented. Our results show a clear transition from non-sequential to sequential double ionization for increasing intensities. Non sequential double ionization is found to be sensitive to the spin configuration of the ionized pair. This asymmetry, also found in experiments of photoionization of Li with synchrotron radiation, shows the evidence of the influence of the exclusion principle in the underlying rescattering mechanism.

description: This paper studies sustainability of economic growth considering the risk of natural disasters caused by pollution in an endogenous growth model with physical and human capital accumulation. It is shown that economic growth is sustainable only if the tax rate on the polluting input is increased over time and that the long-term rate of economic growth follows an inverted V-shaped curve relative to the growth rate of the environmental tax. The social welfare is maximized under a positive steady-state growth in which faster accumulation of human capital compensates the productivity loss due to declining use of the polluting input.

description: In this paper, we present a novel fault injection framework for system call invocation errors, called Phoebe. Phoebe is unique as follows. First, Phoebe enables developers to have full observability of system call invocations. Second, Phoebe generates error models that are realistic in the sense that they mimic errors that naturally happen in production. Third, Phoebe is able to automatically conduct experiments to systematically assess the reliability of applications with respect to system call invocation errors in production. We evaluate the effectiveness and runtime overhead of Phoebe on two real-world applications in a production environment. The results show that Phoebe successfully generates realistic error models and is able to detect important reliability weaknesses with respect to system call invocation errors. To our knowledge, this novel concept of "realistic error injection", which consists of grounding fault injection on production errors, has never been studied before.

description: Simon Szreter’s book Fertility, Class, and Gender in Britain, 1860-1940 argues that social and economic class fails to explain the cross-sectional differences in marital fertility as reported in the 1911 census of England and Wales. Szreter’s conclusion made the book immediately influential, and it remains so. This finding matters a great deal for debates about the causes of the European fertility decline of the nineteenth and twentieth centuries. For decades scholars have argued whether the main forces at work were ideational or social and economic. This note reports a simple re-analysis of Szreter’s own data, which suggests that social class does explain cross-sectional differences in English marital fertility in 1911.
