description: While decade-long research has clearly demonstrated the vast potential of radio frequency (RF) for many human sensing tasks, scaling this technology to large scenarios remained problematic with conventional approaches. Recently, researchers have successfully applied deep learning to take radio-based sensing to a new level. Many different types of deep learning models have been proposed to achieve high sensing accuracy over a large population and activity set, as well as in unseen environments. Deep learning has also enabled detection of novel human sensing phenomena that were previously not possible. In this survey, we provide a comprehensive review and taxonomy of recent research efforts on deep learning based RF sensing. We also identify and compare several publicly released labeled RF sensing datasets that can facilitate such deep learning research. Finally, we summarize the lessons learned and discuss the current limitations and future directions of deep learning based RF sensing.

description: The growth in the railway network in the 1880s and 1890s and the development and adoption of new farming techniques changed the semi-subsistence selector in New South Wales (NSW) into a commercial farmer. They also led to a large increase in the production of wheat and dairy produce and, together with overgrazing in the Western Division, caused a complete relocation of the main types of farming in NSW.

description: We present approximate formulae describing the changes in neutron star parameters caused by the first-order phase transition to an ``exotic'' state (pion or kaon condensate, quark matter) resulting in formation of a mixed-phase core. The analytical formulae for the changes in radius, moment of inertia and the amount of energy released during the core-quake are derived using the theory of linear response of stellar structure to the core transformation. Numerical coefficients in these formulae are obtained for two realistic EOSs of dense matter. The problem of nucleation of the exotic phase as well as possible astrophysical scenarios leading to a core-quake phenomenon is also discussed.

description: We present the first systematic spectropolarimetric study of Luminous Blue Variables (LBVs) in the Galaxy and the Magellanic Clouds, in order to investigate the geometries of their winds. We find that at least half of our sample show changes in polarization across the strong H$α$ emission line, indicating that the light from the stars is intrinsically polarized and therefore that asphericity already exists at the base of the wind. Multi-epoch spectropolarimetry on four targets reveals variability in their intrinsic polarization. Three of these, AG Car, HR Car and P Cyg, show a position angle (PA) of polarization which appears random with time. Such behaviour can be explained by the presence of strong wind-inhomogeneities, or `clumps' within the wind. Only one star, R 127, shows variability at a constant PA, and hence evidence for axi-symmetry as well as clumpiness. However, if viewed at low inclination, and at limited temporal sampling, such a wind would produce a seemingly random polarization of the type observed in the other three stars. Time-resolved spectropolarimetric monitoring of LBVs is therefore required to determine if LBV winds are axi-symmetric in general. The high fraction of LBVs ($>$ 50%) showing intrinsic polarization is to be compared with the lower $\sim$ 20-25 % for similar studies of their evolutionary neighbours, O supergiants and Wolf-Rayet stars. We anticipate that this higher incidence is due to the lower effective gravities of the LBVs, coupled with their variable temperatures within the bi-stability jump regime. This is also consistent with the higher incidence of wind asphericity that we find in LBVs with strong H$α$ emission and recent (last $\sim$ 10 years) strong variability.

description: The distribution of the three Italian species of Rhysodidae was reviewed by re-examining published data, museum conserved and newly collected specimens. Rhysodes sulcatus chronogeonemy encloses a large majority of old findings and only two recently confirmed active populations are recorded after the year 2000. Omoglymmius germari shows a similar picture, with only one recent record (2018) in the Pollino National Park (Basilicata) but a small number of active populations after 2000. Clinidium canaliculatum populations are in a much better conservation status, with about 50 new sites detected after 2000 in the Sila National Park. Threats and research/monitoring needs have been discussed for each species and new IUCN status proposed for Italian populations: Critically Endangered (CR) for Rhysodes and Omoglymmius, Near Threatened (NT) for Clinidium.

Habitat selection and morphology of Saga pedo (Pallas, 1771) in Alps (Susa Valley, Piedmont, NW Italy) (Insecta: Orthoptera, Tettigoniidae, Saginae)

Publisher: name: Fragmenta Entomologica
Year: 2019

description: This paper is a contribution to the knowledge of Saga pedo (Pallas, 1771), summarizing the results of a field study carried out on a population of the Italian W Alps. The peculiar eco-ethological traits of this species make its observation difficult in nature and overall also its biology is little known, especially in Italy. The habitat selection is outlined from 34 unpublished presence data, collected between 2016 and 2018. Moreover, some biometric traits are compared between adult individuals observed in two different and disjointed survey areas. The results show that the environments in which this species lives in Susa Valley should not be referred exclusively to xerothermic oases in strict sense. This species appears to be also associated, in fact, with xeric environments of agricultural origin, mostly abandoned vineyards. These land uses (especially viticulture) could have guaranteed the survival of S. pedo over time. The closure of these open areas by shrub and tree vegetation, constitutes an important threat factor. Phenology and morphology of this species in Susa Valley, seem do not differ from those reported for other European populations. However, from the biometric analysis some significant differences emerge (p<0.05) among the individuals sampled in the two areas, that are difficult to interpret. The observation of imagoes, always combined with high densities of potential prey and sometimes grouped, suggests some hypotheses that it would be interesting to test, to learn more about the ethology and ecology of this enigmatic protected species.

description: We present complete calculations of the electromagnetic form factors of the $Ω^-$ in the spacelike region and in the timelike region. The four elastic form factors: electric charge ($G_{E0}$), magnetic dipole ($G_{M1}$), electric quadrupole ($G_{E2}$) and magnetic octupole ($G_{M3}$), are estimated within the covariant spectator quark model, in terms of the square momentum transfer $q^2$. The free parameters of the $Ω^-$ wave function, including a $S$-wave state and two independent $D$-wave states radial wave functions and the admixture coefficients are fixed by the comparison with the lattice QCD data in the spacelike region ($Q^2=-q^2 \le 0$) and with the recent $e^+ e^- \to Ω^- \bar Ω^+$ data from CLEO in the timelike region ($q^2 > 0$). The estimates in the timelike region for square momentum transfer $q^2 \ge 4 M_Ω^2$ are based on large-$q^2$ asymptotic relations ($M_Ω$ is the $Ω^-$ mass). We examine also the impact of the large-$Q^2$ correlations between different form factors and analyze the possible solutions. The electric quadrupole and the magnetic octupole moments of the $Ω^-$, and the $e^+ e^- \to Ω^- \bar Ω^+$ integrated cross sections for very large $q^2$ are estimated based on the model results.

Resonant relaxation near a massive black hole: the stellar distribution and gravitational wave sources

description: Resonant relaxation (RR) of orbital angular momenta occurs near massive black holes (MBHs) where the stellar orbits are nearly Keplerian and so do not precess significantly. The resulting coherent torques efficiently change the magnitude of the angular momenta and rotate the orbital inclination in all directions. As a result, many of the tightly bound stars very near the MBH are rapidly destroyed by falling into the MBH on low-angular momentum orbits, while the orbits of the remaining stars are efficiently randomized. We solve numerically the Fokker-Planck equation in energy for the steady state distribution of a single mass population with a RR sink term. We find that the steady state current of stars, which sustains the accelerated drainage close to the MBH, can be up to ~10 times larger than that due to non-coherent 2-body relaxation alone. RR mostly affects tightly bound stars, and so it increases only moderately the total tidal disruption rate, which is dominated by stars originating from less bound orbits farther away. We show that the event rate of gravitational wave (GW) emission from inspiraling stars, originating much closer to the MBH, is dominated by RR dynamics. The GW event rate depends on the uncertain efficiency of RR. The efficiency indicated by the few available simulations implies rates ~10 times higher than those predicted by 2-body relaxation, which would improve the prospects of detecting such events by future GW detectors, such as LISA. However, a higher, but still plausible RR efficiency can lead to the drainage of all tightly bound stars and strong suppression of GW events from inspiraling stars. We apply our results to the Galactic MBH, and show that the observed dynamical properties of stars there are consistent with RR.

Proposal for a time-based standard sampling method for the monitoring of Gomphus flavipes (Charpentier, 1825) and Ophiogomphus cecilia (Fourcroy, 1785) (Odonata: Gomphidae)

description: Monitoring of conservation status is an obligation arising from Article 11 of the Habitats Directive for all species of community interest. However, the development of monitoring methods for invertebrate species has received relatively little attention. Gomphus flavipes (Charpentier, 1825) and Ophiogomphus cecilia (Fourcroy, 1785) are two dragonfly species, listed in the annexes of the Habitats Directive, which suffered severe declines in the last century and have since recovered. Methods for the monitoring of these two gomphids have been proposed, but these have not been extensively tested and no abundance classes have been proposed for the evaluation of the conservation status of these species. A time-based standard sampling method is proposed for both species and results from numerous sites in Lombardy, northern Italy, are presented. Applying the standard method revealed that it is common for rivers that high water levels preclude sampling of exuviae through the summer and it is better to allow for two seasons when planning the monitoring. A further result is the fact that it was not always possible to sample the same stretches as the dynamic nature of the rivers and fluctuations in water level lead to some river banks becoming unsuitable for sampling during some visits. In these cases the time-based approach was advantageous, as the method did not need to be modified in response to the original bank section becoming unsuitable.

description: Analyzing the pion-mass dependence of $ππ$ scattering phase shifts beyond the low-energy region requires the unitarization of the amplitudes from chiral perturbation theory. In the two-flavor theory, unitarization via the inverse-amplitude method (IAM) can be justified from dispersion relations, which is therefore expected to provide reliable predictions for the pion-mass dependence of results from lattice QCD calculations. In this work, we provide compact analytic expression for the two-loop partial-wave amplitudes for $J=0,1,2$ required for the IAM at subleading order. To analyze the pion-mass dependence of recent lattice QCD results for the $P$-wave, we develop a fit strategy that for the first time allows us to perform stable two-loop IAM fits and assess the chiral convergence of the IAM approach. While the comparison of subsequent orders suggests a breakdown scale not much below the $ρ$ mass, a detailed understanding of the systematic uncertainties of lattice QCD data is critical to obtain acceptable fits, especially at larger pion masses.

description: Magnetic fields in various astrophysical settings may be helical and, in the cosmological context, may provide a measure of primordial CP violation during baryogenesis. Yet it is difficult, even in principle, to devise a scheme by which magnetic helicity may be detected, except in some very special systems. We propose that charged cosmic rays originating from known sources may be useful for this purpose. We show that the correlator of the arrival momenta of the cosmic rays is sensitive to the helicity of an intervening magnetic field. If the sources themselves are not known, the method may still be useful provided we have some knowledge of their spatial distribution.

description: We present a comprehensive study on the occurrences of the collisional flavor instability (CFI) and the fast flavor instability (FFI) of neutrinos based on a two-dimensional (2D) core-collapse supernova (CCSN) simulation performed with a Boltzmann radiation hydrodynamics code. We find that CFI occurs in a region with the baryon-mass density of $10^{10}\lesssim ρ\lesssim 10^{12}\,\mathrm{g}\,\mathrm{cm}^{-3}$, which is similar to the previous results in one-dimensional (1D) CCSN models. In contrast to 1D, however, the CFI region varies with time vigorously in the 2D model, whereas it had a quiescent structure in 1D. This is attributed to the fact that the turbulent flows advected from a gain region account for the temporal variations. Another noticeable difference from the 1D models is the appearance of resonance-like CFI where number densities of $ν_e$, $\barν_e$ nearly coincide each other. The CFI growth rate there is enhanced and can reach $\sim10^{-3}\,\mathrm{cm}^{-1}$. As for FFI, on the other hand, it appears in three different regions; (1) the region overlapped with the resonance-like CFI, (2) neutrino decoupling regions where $\barν_e$'s are strongly emitted, and (3) optically thin regions where neutral-current scatterings dominate over charged-current reactions. Although overall properties for FFI are consistent with previous studies, we find that the number of electron-neutrinos lepton number crossing (ELN crossing) temporary becomes multiple, which can be assessed accurately only by multi-angle treatments in neutrino transport. We find that the growth rate of FFI is always higher than CFI if both of them occur, which suggests that the former is dominant for the linear evolution.

"The heavens are changing" : nineteenth century protestant missionization on the North Pacific Coast
Creators: name: Neylan, Susan Lynn
Publisher: name: University of British Columbia

description: Christianity is an aspect of Native history, not simply an external force acting upon it. This dissertation examines the nature of Protestant missions (Anglican, Methodist, Salvation Army) in their first few generations on the North Pacific Coast of British Columbia (1857-1901) by focusing on Native roles in Christianization. It pays special attention to the Euro-Canadian missionary perspective on this process, the Native spiritual specialists, missionaries, and Christian lay workers themselves, and particvilar everyday events that illuminate the negotiation of Christian identities. My regional focus examines the territories of the Tsimshianic speaking peoples (Coast Tsimshian, Nisga'a, Gitxsan, Southern Tsimshian, with special emphasis given to the Coast Tsimshian)—the North Pacific Coast of British Columbia, including the Lower Nass and Skeena River watersheds. While they never entirely directed or controlled their own Christianization, Native men and women frequently took the initiative and assumed roles of leadership in mission activity, and within the churches themselves. The relationship forged between Tsimshian and Euro-Canadian missionary was dialogic, although not necessarily a mutually beneficial one. This study examines the function of missions and the meaning of conversion, demonstrating the themes of social action, hegemony, and gender in the writings of non-Native missionaries. Likewise, evangelicalism shaped the emergent forms of Protestant Christianity throughout the region, the discourses about them, and added to their attraction for the Tsimshian. Yet, pre-existing indigenous discourse on transformation also informed Native reception to Christianity, and the nature of the Native roles within the mission sphere did not entirely forsake this spiritual history. While the Euro-Canadian mission record dominates historical missionary sources. Native writings illustrate both a genuine evangelicalism and an indigenized Christianity. Over time. Christian meanings were challenged from both within and without the mission context, through revivalism and group evangelism. While the Tsimshian sought empowerment through new forms of spirituality, those same power mechanisms could confine, challenge, and assault their social and cultiiral structures. The exercise of power at the village level reveals how social and cultural meanings of Tsimshian daily life were disputed, contested, and negotiated.

description: The thermal Hall effect in magnetic insulators has been considered a powerful method for examining the topological nature of charge-neutral quasiparticles such as magnons. Yet, unlike the kagome system, the triangular lattice has received less attention for studying the thermal Hall effect because the scalar spin chirality cancels out between adjacent triangles. However, such cancellation cannot be perfect if the triangular lattice is distorted, which could open the possibility of a non-zero thermal Hall effect. Here, we report that the trimerized triangular lattice of multiferroic hexagonal manganite YMnO$_3$ produces a highly unusual thermal Hall effect due to topological spin fluctuations with the additional intricacy of a Dzyaloshinskii-Moriya interaction under an applied magnetic field. We conclude the thermal Hall conductivity arises from the system's topological nature of spin fluctuations. Our theoretical calculations demonstrate that the thermal Hall conductivity is also related in this material to the splitting of the otherwise degenerate two chiralities, left and right, of its 120$^{\circ}$ magnetic structure. Our result is one of the most unusual cases of topological physics due to this broken $Z_2$ symmetry of the chirality in the supposedly paramagnetic state of YMnO$_3$, with strong topological spin fluctuations. These new mechanisms in this important class of materials are crucial in exploring new thermal Hall physics and exotic excitations.

description: We analyzed the rhythmic, cyclical dorsal-ventral abdominal pumping movements of nymphal and adult Hierodula patellifera (Audinet- Serville 1839), and adult Stagmomantis carolina (Johansson 1763), Tenodera sinensis (de Saussure 1871), Miomantis paykullii (Stål 1871), and Sphodromantis lineola (Burmeister 1838) using a combination of customized video analysis software and frame-by-frame video analyses. Despite the phylogenetic and ecological diversity of these species, we found fundamental similarities in the overall, intermittent patterns of their abdominal pumping movements. In adults of all species, intermittent bouts of abdominal pumping had median durations of 64-89 sec, and were separated by intervals with median durations of 10-25 sec. Bouts began with rhythmic upward abdominal deflections of progressively increasing amplitude and frequency which were superimposed on an overall, progressive abdominal elevation. Bouts ended with 1-4 very high amplitude, low frequency upward deflections after which the abdomen returned to its horizontal (resting) position. In H. patellifera, the overall adult pattern emerged gradually during larval development. Given the diversity of the species tested, our data suggest that intermittent abdominal pumping (which has been associated with respiratory behavior in insects) may be independent of ecological niche or acute environmental stressors in mantises. Instead, our data support the hypothesis that these apparently respiratory related, intermittent abdominal pumping movements are an emergent property of the mantis central nervous system organization.

description: In terms of value added, olive oil is one of the most important agricultural commodities in Tunisia. It is also the most important agricultural export commodity. Tunisia ranks second to Spain in world olive oil exports. Currently these exports account for about 20 percent of total export earnings of Tunisia. This is equivalent to about 40 percent of total agricultural export earnings. Tunisia is by far the largest olive oil producing country in North Africa and the Middle East and ranks sixth among the world's producers of olive oil. Considering the adaptability of the olive tree to the climate and soil conditions of Tunisia, olive culture is expected to maintain its importance in Tunisian agriculture. However, the economic benefits which could be derived from the olive oil sector will be directly affected by national policy regarding marketing and pricing of the commodity. In particular, the role that prices play in providing necessary incentives to induce technological change in production and marketing should not be underestimated.

description: Recently, a covariant spherically symmetric model of a black hole within the framework of loop quantum gravity (LQG), characterized by a quantum parameter $r_0$ or $λ$, has been proposed. To derive constraints on the LQG-corrected parameter, we explore observational constraints imposed on $r_0$ and $λ$ through investigations of the light deflection, the Shapiro time delay, the precession of perihelia, and the geodetic precession test. Among these constraints, the tightest one arises from the Shapiro time delay measured by the Cassini mission, yielding an upper constraint of approximately $10^{-5}$.

Towards the second goal, some aspects were analyzed based on the best available, but rather fragmentary information from initial trials of hazelnut varieties suited to Michigan conditions and small initial onfarm plantings. The role of a strategic marketing plan and marketing organizations are included in the analysis as they seem to have been influential in the development of the established Oregon hazelnut industry and can be important if a hazelnut industry develops in Michigan. Since experience with Michigan hazelnut production up to now is very limited. additional information and in-depth studies regarding technical and economic aspects are needed to provide more comprehensive information on economic potential of a commercial hazelnut industry in Michigan. One area that needs additional data and analysis is that of costs and returns analysis for Michigan grown hazelnuts.

description: Different properties of dark matter haloes, including growth rate, concentration, interaction history, and spin, correlate with environment in unique, scale-dependent ways. While these halo properties are not directly observable, galaxies will inherit their host haloes' correlations with environment. In this paper, we show how these characteristic environmental signatures allow using measurements of galaxy environment to constrain which dark matter halo properties are most tightly connected to observable galaxy properties. We show that different halo properties beyond mass imprint distinct scale-dependent signatures in both the galaxy two-point correlation function and the distribution of distances to galaxies' $k$th nearest neighbours, with features strong enough to be accessible even with low-resolution (e.g., grism) spectroscopy at higher redshifts. As an application, we compute observed two-point correlation functions for galaxies binned by half-mass radius at $z=0$ from the Sloan Digital Sky Survey, showing that classic galaxy size models (i.e., galaxy size being proportional to halo spin) as well as other recent proposals show significant tensions with observational data. We show that the agreement with observed clustering can be improved with a simple empirical model in which galaxy size correlates with halo growth.

description: The aluco-group of the Indo-Australian genus Anisoneura is revised with characterisation of its component species and updating of their distribution. Types of all but one nominal taxa of the group are illustrated. The concept of Anisoneura zeuzeroides Guenée, 1852 is restricted to sole populations from Western New Guinea, while Moluccan (including Kei Islands’) populations previously ascribed to this nominal taxon are distinguished as Anisoneura sphingoides C. Felder, 1861 stat. rev. (= Anisoneura depressa Hulstaert, 1924, syn. nov.), and those from Eastern New Guinea are re-evaluated as Anisoneura papuana Hampson, 1913 stat. rev. The unusual circumstances of the scarce divergence in genitalia characters between species looking externally different (either sphingoides or zeuzeroides vs aluco) and vice versa, that is species almost indistinguishable in habitus albeit strongly differentiated in genitalia (either sphingoides or zeuzeroides vs papuana), is stressed. Lectotypes to Anisoneura hypocyana Guenée, 1852 and Anisoneura sphingoides C. Felder, 1861 are designated.

description: This paper reports on the integration of runtime monitoring into fully-electric aircraft designed by Volocopter, a German aircraft manufacturer of electric multi-rotor helicopters. The runtime monitor recognizes hazardous situations and system faults. Since the correct operation of the monitor is critical for the safety of the aircraft, the development of the monitor must follow strict aeronautical standards. This includes the integration of the monitor into different development environments, such as log-file analysis, hardware/software-in-the-loop testing, and test flights. We have used the stream-based monitoring framework RTLola to generate monitors for a range of requirements. In this paper, we present representative monitoring specifications and our lessons learned from integrating the generated monitors. Our main finding is that the specification and the integration need to be decoupled, because the specification remains stable throughout the development process, whereas the different development stages require a separate integration of the monitor into each environment. We achieve this decoupling with a novel abstraction layer in the monitoring framework that adapts the monitor to each environment without affecting the core component generated from the specification. The decoupling of the integration has also allowed us to react quickly to the frequent changes in the hardware and software environment of the monitor due to the fast-paced development of the aircraft in a startup company.

description: We study experimentally interaction-driven spin oscillations in optical lattices in the presence of an off-resonant microwave field. We show that the energy shift induced by this microwave field can be used to control the spin oscillations by tuning the system either into resonance to achieve near-unity contrast or far away from resonance to suppress the oscillations. Finally, we propose a scheme based on this technique to create a flat sample with either singly- or doubly-occupied sites, starting from an inhomogeneous Mott insulator, where singly- and doubly-occupied sites coexist.

description: On-farm trials conducted in Zimbabwe communal areas (peasant sector) have demonstrated the existence of a yield gap between potential farm yields and those achieved by farmers. This study utilizes the experimental and survey approach to quantify the size of the maize and groundnut yield gaps at the farm level and evaluates the economic returns associated with the yield increasing technologies. Three major conclusions drawn from the study are: First, the diagnostic survey and the yield gap package approach substituted for each other in identifying technical constraints for designing on-farm trails. Second, the magnitude of the yield gap alone could not be used to justify the initiation of a groundnut trial program versus maize, since costs of recovering the gap were higher in the former crop than the latter. Third, sensitivity analysis models showed that either the groundnut price must rise by 43 percent or the yield from the improved package must increase by 26 percent to make this crop as profitable as maize. Alternatively, introducing a herbicide in groundnut production would only require an increase in groundnut price and yield of 16 percent and 10 percent respectively.
The selected lymphocyte antibody method : a novel approach for the generation and genetic analysis of human cytomegalovirus (HCMV) neutralizing monoclonal IgG antibodies

description: The generation of human monoclonal antibodies that may be clinically useful is hampered by the lack of an efficient, applicable technology. In this thesis I report the development of the Selected Lymphocyte Antibody Method (SLAM) as an alternative approach to generate monoclonal antibodies and to facilitate the analysis of the human humoral immune response. SLAM technology is based upon the molecular cloning and expression of immunoglobulin heavy and light chain variable region cDNAs from single B lymphocytes that have been identified in a modified hemolytic plaque assay as secreting immunoglobulin which is specific for a target antigen. SLAM technology was first developed in a murine model. Immunoglobulin variable region cDNAs were RT-PCR amplified from single murine B lymphocytes that secreted immunoglobulin which is specific for an epitope found in gpll6 of the Human Cytomegalovirus (HCMV) or in gpl20 of HIV-1. These immunoglobulin variable regions were then cloned and expressed in the context of human immunoglobulin constant regions. The resulting chimeric immunoglobulins were shown to reproduce the same specificity as the "parental" immunoglobulin. To generate human monoclonal antibodies that were specific for gpl 16, peripheral blood B lymphocytes from a single HCMV immune donor were cultured at limiting dilution in the "EL4.B5" B-cell culture system. 107 single B lymphocytes, corrresponding to 34 clones that secreted gpll6-specific immunoglobulin, were identified by hemolytic plaque assay and then isolated by micromanipulation. Immunoglobulin variable region cDNAs were successfully RT-PCR amplified from 29 of the 34 clones. Sequence analysis of the V region cDNAs showed a remarkable restriction in the use of heavy chain variable and joining gene segments as well as restriction in the use of kappa light chain variable and joining gene segments in the associated light chains. Two independent B cell clonotypes were identified based on the utilization of different diversity gene segments in the heavy chain variable regions. Two recombinant monoclonal antibodies (mAbs) that represent each clonotype were expressed and were shown to neutralize HCMV in vitro. Thus, SLAM technology facilitated the generation of two potentially clinically useful antibodies and may be used in the future to generate mAbs against a wide variety of pathogens.

description: The need of fiscal consolidation is likely to dominate the policy agenda in the next decade; starting from statistical evidence on the conduct of fiscal policy in the EMU area over the last decade, this paper addresses the optimality of alternative fiscal consolidation strategies. We explore the welfare properties. In this paper we explore the welfare properties
of debt-targeting fiscal policy implemented through, alternatively, distortionary taxation on consumption, labour and capital income or productive and wasteful government expenditure.
We build a general equilibrium model with various distortions in order to evaluate the welfare ranking of alternative fiscal policy configurations under different monetary policy regimes.
Our results show the welfare superiority of fiscal adjustments based on productive government expenditure, whereas the use of a capital income tax rate as fiscal instruments yields the highest welfare loss.
Consumption multipliers of different types of public spending: a structural vector error correction analysis for the UK

description: The aim of this paper is to investigate the relationship between government spending and private consumption in the UK, for which there is scarce previous empirical evidence. We disaggregate public expenditure into three categories and search for the corresponding private consumption multipliers. Our analysis includes the estimation of a structural vector error correction (SVEC) model, using quarterly non-interpolated data for the period 1981:1 – 2007:4. Initially, we estimate negative effects on consumption of shocks to total public spending. Then, using the spending decomposition, we find that while shocks to public wages crowd-out private consumption as predicted by neoclassical models, shocks to the non-systematic component of social spending and government purchases of goods and services generate a positive reaction, so to crowd-in private consumption. Thus, the qualitative and quantitative dimensions of fiscal multipliers on private consumption change across different public spending categories. Our findings suggest that any empirical support of competing theoretical models on the issue would benefit from a disaggregation of government expenditure, rather than focusing on the aggregate measure.
