Subjects: International Development

description: The benefit of growth experienced since 2000 in Africa has not been broadly shared. Poverty fell by only 8.0 percentage points between 1990 and 2010 compared to the targeted 28.3 percentage points by 2015. Although income inequality fell by 4.3 percent between 1990 and 2009, Africa remains the second most unequal region globally after Latin America and the Caribbean region. Fiscal policies play important roles in reducing poverty and inequality through such instruments as taxes, transfers and government spending. Countries with high fiscal space tend to have lower poverty rates than those with lower tax revenue to GDP ratios. Indeed, fiscal space alone tends to account for 16.5 percent of changes in poverty reduction. Institutions play an important role in increasing fiscal space in Africa. Countries with increasing participatory, transparent and accountable budgetary process tend to have stronger impact of fiscal space on poverty and inequality reduction. Although 29 countries recorded declines in the distributional effectiveness of their fiscal policies over time, the distributional impact rose by 35 percent or more in countries such as Angola, Mozambique, South Africa and Togo. This paper calls for enhancing the non-extractive revenues by diversifying revenues sources from the extractive sectors and improving progressive taxation in countries with high fiscal space and high income inequality. Heavy investment in quality and accessible education and health services, and social programs are also vital to reduce poverty and inequality in Africa.
The symmetry, connecting the processes in 2- and 4-dimensional space-times, and the value $α_0 = 1/4π$ for the bare fine structure constant

description: Defined by Bogoliubov coefficients the spectra of pairs of Bose (Fermi) massless quanta, emitted by point mirror in 1+1-space, coincide up to multiplier $e^2/ \hbar c$ with the spectra of photons (scalar quanta), emitted by point electric (scalar) charge in 3+1-space for any common trajectory of the sources. The integral connection of the propagator of a pair in 1+1-space with the propagator of a single particle in 3+1-space leads to equality of the vacuum-vacuum amplitudes for charge and mirror if the mean number of created particles is small and the charge $e=\sqrt{\hbar c}$. Due to the symmetry the mass shifts of electric and scalar charges, the sources of Bose-fields with spin 1 and 0 in 3+1-space, for the trajectories with subluminal relative velocity $β_{12}$ of the ends and maximum proper acceleration $w_0$ are expressed in terms of heat capacity (or energy) spectral densities of Bose and Fermi massless particle gases with temperature $w_0/2π$ in 1+1-space. The energy of one-dimensional proper field oscillations is partly deexcited in the form of real quanta and partly remains in the field. As a result, the mass shift of accelerated electric charge is nonzero and negative, while that of scalar charge is zero. The traces of the Bogoliubov coefficients $α^{B,F}$ describe the vector and scalar interactions of accelerated mirror with a uniformly moving detector and were found in analytical form. The symmetry predicts one and the same value $e_0=\sqrt{\hbar c}$ for electric and scalar charges in 3+1-space. The arguments are adduced in favour of that this value and the corresponding value $α_0=1/4π$ for fine structure constant are the bare, nonrenormalized values.

description: The dense medium created in Au + Au collisions at the Relativistic Heavy-Ion Collider (RHIC) significantly suppresses particle production from hard scattering processes and their characteristic back-to-back angular correlation. We present a simple model of jet absorption in dense matter which incorporates a realistic nuclear geometry. Our calculations are performed at the jet level and assume independent jet fragmentation in the vacuum. This model describes quantitatively the centrality dependence of the observed suppression of the high $p_T$ hadron yield and of the back-to-back angular correlations. The azimuthal anisotropy of high $p_T$ particle production can not be accounted for using a realistic nuclear geometry.

description: We investigate the duality conjecture "Complexity=Action" (CA) for Born-Infeld (BI) gravity model and derive the growth rate of its action within the Wheeler-DeWitt (WDW) patch, which is believed to be dual to the growth rate of quantum complexity of holographic boundary state. In order to find the correct on-shell action, we use direct variational procedure to find proper boundary and corner terms. We find out that the late-time behavior of holographic complexity is the well-known two times of energy, as expected.

description: Over the past decade, Africa has experienced unprecedented demand for large scale agricultural land. Africa accounts for more than half of the volume of land acquired and close to two-thirds of the total deals globally. Yet, there is dearth of empirical evidence on demand for arable land in Africa. This paper provides some econometric analysis of the key determinants of large scale land acquisition in Africa. Evidences from bivariate and multi-variate analyses show that both economic and institutional factors play some critical role in explaining demand for large scale arable land in Africa. Key determinants include high yield gap, low per capita income, abundant inland water resources, low property rights and prevalence of corruption. To make the recent surge in land demand beneficial in terms of agricultural transformation, improved livelihoods for the rural people and reduce poverty, it is important to ensure both economic and institutional factors create positive incentives to the local economy, rural farmers and the poor. This includes making fertilizer available, increasing local farmers’ access to agricultural infrastructures (e.g. irrigation, tractors and storage facilities), investing in land registration and certification, and improving land governance and procedures.

description: Concurrent with the rapid development of the market for catastrophe (cat) bonds, a steady decline in their risk premia has been observed. Whether the latter trend is consistent with the evolution of natural disasters risk is an open question. Indeed, a large share of outstanding risk capital in the cat bonds market appears to be exposed to some climate change-related risk as, for instance, hurricane risk, which global warming is expected to enhance. This paper addresses the above issue by assessing the global warming evidence, its implications for the natural environment and the drivers of cat bonds risk premia. We find that radiative forcing, i.e. the net insolation absorbed by the Earth, drives the warming trend in temperature anomalies and the trend evolution of natural phenomena, such as ENSO and Atlantic hurricanes, enhancing their disruptive effects. Hence, in the light of the ongoing contributions of human activity to radiative forcing, i.e., greenhouse gases emissions, natural disasters risk appears to be on a raising trend. Yet, the latter does not appear to have been accurately priced in the cat bonds market so far. In fact, while we find that the falling trend in cat bonds multiples is accounted by the expansionary monetary stance pursued by the Fed, we do also find evidence of significant undervaluation of natural disasters risk.

description: Gary Hall is no relation to Philip Streatfeild. He had seen a magazine 'The Reveille 5th Plymouth Troop' magazine on the internet and because of his connection with the Sea Scouts, bought it.
Philip Streatfeild was a Commissioner in the Sea Scouts and because he was due to become the Captain of the H M S Triumph, he resigned from the Sea Scouts. He was due to sail to the China Sea on H M S Triumph but became ill after a previous injury to his scalp and so did not sail. He went to hospital in Plymouth and he was unfit to command a ship being diagnosed with arterio sclerosis.
H M S Triumph went on to Gallipoli where it was later sunk by a U Boat. A lucky escape for Philip.
The magazine was brought in to be scanned/photographed along with a 'Silk' from H M S Triumph.
He died in 1960.

description: We investigate how the selection process of a leader affects team performance with respect to social learning. We use a lab experiment in which an incentivized guessing task is repeated in a star network with the leader at the center. Leader selection is either based on competence, on self-confidence, or made at random. Teams with random leaders do not underperform compared to competent leaders, and they even outperform teams whose leader is selected based on self-confidence. The reason is that random leaders are better able to use the knowledge within the team. We can show that it is the declaration of the selection procedure which makes non-random leaders overly influential. We set up a horse race between several rational and naïve models of social learning to investigate the micro-level mechanisms. We find that overconfidence and conservatism contribute to the fact that overly influential leaders mislead their team.

Complete Resolution of the Quantum Zeno Paradox for Outside Observers

description: The quantum Zeno paradox is fully resolved for purely indirect and incomplete measurements performed by the detectors outside the system. If the outside detectors are prepared to observe propagating signals of a decay event of an excited state in the core region, the survival probability of the state is not changed at all by the outside measurements, as long as the wavefunction of the signals does not have reflectional-wave contributions going back to the core by the outside detectors. The proof is independendent of the decay law of the survival probabilities. Just watching frequently from outside (observation) cannot be regarded as a measurement which yields the quantum Zeno effect.

description: The solar corona is a highly-structured plasma which can reach temperatures of more than 2 MK. At low frequencies (decimetric and metric wavelengths), scattering and refraction of electromagnetic waves are thought to considerably increase the imaged radio source sizes (up to a few arcminutes). However, exactly how source size relates to scattering due to turbulence is still subject to investigation. The theoretical predictions relating source broadening to propagation effects have not been fully confirmed by observations due to the rarity of high spatial resolution observations of the solar corona at low frequencies. Here, the LOw Frequency ARray (LOFAR) was used to observe the solar corona at 120–180 MHz using baselines of up to ~3.5 km (corresponding to a resolution of ~1–2') during the partial solar eclipse of 2015 March 20. A lunar de-occultation technique was used to achieve higher spatial resolution (~0.6') than that attainable via standard interferometric imaging (~2.4'). This provides a means of studying the contribution of scattering to apparent source size broadening. It was found that the de-occultation technique reveals a more structured quiet corona that is not resolved from standard imaging, implying scattering may be overestimated in this region when using standard imaging techniques. However, an active region source was measured to be ~4' using both de-occultation and standard imaging. This may be explained by the increased scattering of radio waves by turbulent density fluctuations in active regions, which is more severe than in the quiet Sun.

description: In this article, we continue our study of the ring of Baire one functions on a topological space $(X,τ)$, denoted by $B_1(X)$ and extend the well known M. H. Stones's theorem from $C(X)$ to $B_1(X)$. Introducing the structure space of $B_1(X)$, an analogue of Gelfand Kolmogoroff theorem is established. It is observed that $(X,τ)$ may not be embedded inside the structure space of $B_1(X)$. This observation inspired us to introduce a weaker form of embedding and show that in case $X$ is a $T_4$ space, $X$ is weakly embedded as a dense subspace, in the structure space of $B_1(X)$. It is further established that the ring $B_1^{*}(X)$ of all bounded Baire one functions is a C-type ring and also, the structure space of $B_1^{*}(X)$ is homeomorphic to the structure space of $B_1(X)$. Introducing a finer topology $σ$ than the original $T_4$ topology $τ$ on $X$, it is proved that $B_1(X)$ contains free (maximal) ideals if $σ$ is strictly finer than $τ$. It is also proved that $τ= σ$ if and only if $B_1(X) = C(X)$. Moreover, in the class of all perfectly normal $T_1$ spaces, $B_1(X) = C(X)$ is equivalent to the discreteness of the space $X$.

subject: Oil Price Speculation

description: This paper provides an analysis of the link between the global market for crude oil and oil futures risk premium at the aggregate level. It offers empirical evidence on whether the compensation for risk required by the speculators depends on the type of the structural shock of interest. Understanding the response of the risk premium to unexpected changes in the price of oil can be useful to address some research questions, among which: what is the relationship between crude oil risk premium and unexpected rise in the price of oil? On average, what should speculators expect to receive as a compensation for the risk they are taking on? This work is based on a Structural Vector Autoregressive (SVAR) model of the crude oil market. Two main results emerge. First, the impulse response analysis provides evidence of a negative relationship between the risk premium and the changes in the price of oil triggered by shocks to economic fundamentals. Second, this analysis shows that the historical decline of the risk premium can be modelled as a part of endogenous effect of the oil market driven shocks.

The cut-off and dimensional regularization schemes are discussed and compared. It is demonstrated that the prescriptions are consistent with each other and lead to the same physical consequences. Stability of the ground state is discussed for a U(1) model that is supposed to mimic the Standard Model extended to 5 dimensions. It has been shown that fermionic Kaluza-Klein modes can dramatically influence the shape of the effective potential shifting the instability scale even by several orders of magnitude.

description: This paper studies the relationship between ¯scal decentralization and electoral accountability, by analyzing how decentralization impacts upon incentive and selection e®ects, and thus on voter welfare. The model abstracts from features such as public good spillovers or economies of scale, so that absent elections, voters are indi®erent about the ¯scal regime. The e®ect of ¯scal centralization on voter welfare works through two channels: (i) via its e®ect on the probability of pooling by the bad incumbent; (ii) conditional on the probability of pooling, the extent to which, with centralization, the incumbent can divert rents in some regions without this being detected by voters in other regions (selective rent diversion). Both these e®ects depend on the information structure; whether voters only observe ¯scal policy in their own region, in all regions, or an intermediate case with a uniform tax across all regions. More voter information does not necessarily raise voter welfare, and under some conditions, voter would choose uniform over di®erentiated taxes ex ante to constrain selective rent diversion.

description: Is conformity amongst similar individuals consistent with self-interested behavior? We consider a model of incomplete information in which each player receives a signal, interpreted as an allocation to a role, and can make his action choice conditional on his role. Our main result demonstrates that ‘near to’ any correlated equilibrium is an approximate correlated equilibrium ‘with conformity’ — that is, an equilibrium where all ‘similar players’ play the same strategy, have the same probability of being allocated to each role, and receive approximately the same payoff; in short, similar players ‘behave in an identical way’ and are treated nearly equally. To measure ‘similarity’ amongst players we introduce the notions of approximate substitutes and a (δ, Q)-class games — a game with Q classes of players where all players in the same class are δ-substitutes for each other.

description: We perform a series of two-dimensional, axisymmetric, magnetohydrodynamic simulations of the rotational collapse of a supernova core. In order to calculate the waveforms of the gravitational wave, we derive the quadrupole formula including the contributions from the electromagnetic fields. Recent stellar evolution calculations imply that the magnetic fields of the toroidal components are much stronger than those of the poloidal ones at the presupernova stage. Thus, we systematically investigate the effects of the toroidal magnetic fields on the amplitudes and waveforms. Furthermore, we employ the two kinds of the realistic equation of states, which are often used in the supernova simulations. Then, we investigate the effects of the equation of states on the gravitational wave signals. With these computations, we find that the peak amplitudes are lowered by an order of 10% for the models with the strongest toroidal magnetic fields. However, the peak amplitudes are mostly within sensitivity range of laser interferometers such as TAMA and the first LIGO for a source at a distance of 10 kpc. Furthermore, we point out that the amplitudes of second peaks are still within the detection limit of the first LIGO for the source, although the characteristics of second peaks are reduced by the magnetic fields. We stress the importance of the detection, since it will give us information about the angular momentum distribution of massive evolved stars. When we compare the gravitational waves from the two realistic equation of states, significant differences are not found, except that the typical frequencies of the gravitational wave become slightly higher for the softer equation of state.

We found the 22 known variables plus an additional new Cepheid located about 10' from the cluster center. The accuracy of the photometry allowed us to derive B, V and I mean magnitudes with an uncertainty lower than 0.02 mag for 22 out of the 23 objects, with the exception of only one Cepheid (WS9) which presents a noisy light curve due to the probable occurrence of image blending. As a result, we provide accurate observational data for a substantial sample of variables all lying at the same distance and with a common original composition. The resulting period-luminosity relations are presented and briefly discussed.

The asynchronous parallelization of the simulation makes very large system and sample sizes possible. Our high accuracy results are fully consistent with predictions from conformal field theory. The numerical results for the Moebius strip and the number distribution of winding clusters on the torus await theoretical explanation. To our knowledge, this study is the first of its kind.

description: Developments in mobile robot navigation have enabled robots to operate in warehouses, retail stores, and on sidewalks around pedestrians. Various navigation solutions have been proposed, though few as widely adopted as ROS Navigation. 10 years on, it is still one of the most popular navigation solutions. Yet, ROS Navigation has failed to keep up with modern trends. We propose the new navigation solution, Navigation2, which builds on the successful legacy of ROS Navigation. Navigation2 uses a behavior tree for navigator task orchestration and employs new methods designed for dynamic environments applicable to a wider variety of modern sensors. It is built on top of ROS2, a secure message passing framework suitable for safety critical applications and program lifecycle management. We present experiments in a campus setting utilizing Navigation2 to operate safely alongside students over a marathon as an extension of the experiment proposed in Eppstein et al. The Navigation2 system is freely available at https://github.com/ros-planning/navigation2 with a rich community and instructions.

description: Rita brought in a mule shoe and a four page written history of First World War - British Army Mules "Taunton" Mule Depots. Bratton Farm was used as a mule training depot and had a 5 ton weigh station. The mules were brought in by train to Minehead Station and then driven up the Avenue, Minehead to the farm. The owner of Bratton Court Farm is Hon. Roland Lytton. This mule training depot only operated until 1916. A mule shoe was found at the farm along with several mule rings. The mule shoe was brought in to be photographed.
b-physics signals of the lightest CP-odd Higgs in the NMSSM at large tan beta

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the low energy phenomenology of the lighter pseudoscalar $A_1^0$ in the NMSSM. The $A_1^0$ mass can naturally be small due to a global $U(1)_R$ symmetry of the Higgs potential, which is only broken by trilinear soft terms. The $A_1^0$ mass is further protected from renormalization group effects in the large $\tan β$ limit. We calculate the $b \to s A_1^0$ amplitude at leading order in $\tan β$ and work out the contributions to rare $K$, $B$ and radiative $Υ$-decays and $B -\bar B$ mixing. We obtain constraints on the $A_1^0$ mass and couplings and show that masses down to ${\cal{O}}(10)$ MeV are allowed. The $b$-physics phenomenology of the NMSSM differs from the MSSM in the appearance of sizeable renormalization effects from neutral Higgses to the photon and gluon dipole operators and the breakdown of the MSSM correlation between the $B_s \to μ^+ μ^-$ branching ratio and $B_s - \bar B_s$ mixing. For $A_1^0$ masses above the tau threshold the $A_1^0$ can be searched for in $b \to s τ^+ τ^-$ processes with branching ratios $\lsim 10^{-3}$.

Public Economics

description: We consider a general equilibrium local public goods economy in which agents have two distinguishing characteristics. The first is ‘crowding type,’ which is publicly observable and provides direct costs or benefits to the jurisdiction (coalition or firm) the agent joins. The second is taste type, which is not publicly observable, has no direct effects on others and is defined over private good, public goods and the crowding profile of the jurisdiction the agent joins. The law of demand suggests that as the quantity of a given crowding type (plumbers, lawyers, smart people, tall people, nonsmokers, for example) increases, the compensation that agents of that type receive should go down. We provide counterexamples, however, that show that some agents of a given crowding type might actually benefit when the proportion of agents with the same crowding type increases. This reversal of the law of demand seems to have to do with an interaction effect between tastes and skills, something difficult to study without making these classes of characteristics distinct. We argue that this reversal seems to relate to the degree of difference between various patterns of tastes. In particular, if tastes are homogeneous, the law of demand holds.
What exactly is a parton density?

description: I give an account of the definitions of parton densities, both the conventional ones, integrated over parton transverse momentum, and unintegrated transverse-momentum-dependent densities. The aim is to get a precise and correct definition of a parton density as the target expectation value of a suitable quantum mechanical operator, so that a clear connection to non-perturbative QCD is provided. Starting from the intuitive ideas in the parton model that predate QCD, we will see how the simplest operator definitions suffer from divergences. Corrections to the definition are needed to eliminate the divergences. An improved definition of unintegrated parton densities is proposed.

description: This paper investigates the possible negative effect of external crises, sudden stops in capital flows and currency crises in emerging market economies. We find that a current account reversal has an important effect, both direct and indirect, on economic growth, and depresses GDP by about 1 percentage point in the current year, when using a broad group of emerging markets. On the other hand, currency crises themselves, identified as a sharp depreciation, do not appear to have a significant direct impact on growth. Their overall effect on growth is positive, though rather insignificant from an economic point of view. The joint occurrence of the currency crisis and the current account reversal appears to be the most damaging event for economic growth. Both the direct and compounded effects are about 5 times larger than those of the reversal in the current year. The estimated cumulative losses for current account reversals and the joint crisis are 2 and 21 percentage points, respectively. The time necessary for the adjustment of actual growth back to its equilibrium rate is roughly 2.5 years after the current account reversal and 6.5 years after the joint occurrence of the currency crisis and the reversal.

description: According to economic theory, the capital inflows reversal – so-called sudden stop – has a significant negative effect on economic growth. This paper investigates the direct impact of current account reversals on growth in Central and Eastern European countries. Two steps to conduct the analysis are applied. In the first step we estimate the standard growth equation augmented by an effect of the current account reversal. We find that after a current account reversal the growth rate declines by 1.10 percentage points in the current year. The subsequent analysis of the adjustment dynamics builds upon the notion of convergence. We find the unconditional and conditional convergence coefficients to be - 0.47 and -0.52, respectively. This implies that the consequences of the reversal are likely eliminated after 3.3 years when the actual growth rate is back at its equilibrium level, ceteris paribus. Finally, the cumulative loss associated with a sudden stop in capital flows is about 2.3 percentage points. We infer that Central and Eastern European countries are relatively flexible in terms of adjustment and reallocation of resources given the findings in similar literature examining either a more general sample or concentrating on rather different regions.

description: Percy was born 8th January 1897 in Tenterden, Kent to Charles Henry (a farmer) and Julia Isabella Bourner. In 1911, Percy, his parents and siblings were all living in Canada, having emigrated there in 1909. Percy was a farmer before the war. He married Louise Stemp.

Percy was a Private in the 87th Battalion Canadian Infantry (Quebec Regiment) - regiment number 177564. He died 21st October 1916. He was firstly reported missing before being reported killed in action. It was not until December that it was confirmed that he had died in action. He is buried at the Adanac Military Cemetery, Miraumont and Pys.

There is a family story that Percy was in a convalescent home when a nurse took him on a boat trip on the lake in the grounds. The boat capsized and Percy died due to his injuries.
The Cyclic Model Simplified

description: The Cyclic Model attempts to resolve the homogeneity, isotropy, and flatness problems and generate a nearly scale-invariant spectrum of fluctuations during a period of slow contraction that precedes a bounce to an expanding phase. Here we describe at a conceptual level the recent developments that have greatly simplified our understanding of the contraction phase and the Cyclic Model overall. The answers to many past questions and criticisms are now understood. In particular, we show that the contraction phase has equation of state w>1 and that contraction with w>1 has a surprisingly similar properties to inflation with w < -1/3. At one stroke, this shows how the model is different from inflation and why it may work just as well as inflation in resolving cosmological problems.
