description: Nowadays, all financial institutions rely on ICT diffusion in gathering, processing, analyzing and providing information to meet customers’ needs. In an environment that is complex, competitive and dynamic, the diffusion of ICT in the highly information sensitive banking sector comes with mixed blessings especially in African context with under developed ICT tools. This article seeks to investigate the effects of information and communication technologies (ICT) diffusion on bank stability in Africa using a panel of 45 countries from 2004 to 2020. We employ the system GMM as well as a two step GMM method of estimation to check for robustness of the relationship between the variables. The results show a positive and significant relationship between ICT and bank stability. This implies that policies aimed at boosting ICT diffusion should not be neglected.

description: Emotion detection (ED) aims to identify people's emotions automatically. However, most ED applications do not consider individuals who express emotions differently, such as people with autism. Although studies have already focused on creating ED models tailored for children with ASD, this application of ED suffers from a scarcity of resources and remains underperforming compared to the state-of-the-art ED models for the general population. This thesis addresses the gap in automatic ED between the general population and autistic children while ensuring an ethically driven approach, i.e., having the well-being of participants as the main priority during the whole research process. To meet our research objectives, we created a data collection framework that minimises emotional disruption to the participants, respects their privacy and rights according to GDPR, and provides a dataset that can be shared with the research community. We created CALMED, a multimodal annotated dataset for ED featuring children with autism that includes privacy-preserving features, novel target emotion classes, annotations provided by the participants' parents and a researcher specialist who works with children with ASD. Using the CALMED dataset, we created hundreds of models with unique configurations and analysed them to explore the effectiveness of various methods for multimodal ED in autism. Then, utilising the knowledge acquired in this analysis, we proposed a multimodal ED model that outperformed the previous state-of-the-art, reaching 81.56% and 75.47% for accuracy and balanced accuracy, respectively. Finally, we created and shared many systems to support the data acquisition process and data experiments creation and analysis. We placed great importance on ensuring reproducibility, reusability, and ethical conduct. This research has made significant contributions to the field of ED applied to ASD. It has provided a valuable dataset, analytical insights, a state-of-the-art model, and many computer systems that can serve as a groundwork for future work.

description: Navigation systems are used daily. While different types of navigation systems exist, inertial navigation systems (INS) have favorable properties for some wearables which, for battery and form factors may not be able to use GPS. Earables (aka ear-worn wearables) are living a momentum both as leisure devices, and sensing and computing platforms. The inherent high signal to noise ratio (SNR) of ear-collected inertial data, due to the vibration dumping of the musculoskeletal system; combined with the fact that people typically wear a pair of earables (one per ear) could offer significant accuracy when tracking head movements, leading to potential improvements for inertial navigation. Hence, in this work, we investigate and propose PilotEar, the first end-to-end earable-based inertial navigation system, achieving an average tracking drift of 0.15 m/s for one earable and 0.11 m/s for two earables.

description: We use multi-spacecraft observations of invididual type III radio bursts in order to calculate the directivity of the radio emission, to be compared to the results of ray-tracing simulations of the radio-wave propagation and probe the plasma properties of the inner heliosphere. Ray-tracing simulations of radio-wave propagation with anisotropic scattering on density inhomogeneities are used to study the directivity of radio emissions. Simultaneous observations of type III radio bursts by four widely-separated spacecraft are used to calculate the directivity and position of the radio sources. The shape of the directivity pattern deduced for individual events is compared to the directivity pattern resulting from the ray-tracing simulations. We show that simultaneous observations of type radio III bursts by 4 different probes provide the opportunity to estimate the radio source positions and the directivity of the radio emission. The shape of the directivity varies from one event to another, and is consistent with anisotropic scattering of the radio-waves.

description: We propose a new model for naturally light Dirac neutrinos and explain the baryon asymmetry of the universe through neutrinogenesis. We extend the standard model with a real singlet scalar, a heavy singlet Dirac fermion and a heavy doublet scalar besides three right-handed neutrinos, respecting lepton number conservation and a Z_2 symmetry. The neutrinos acquire small Dirac masses due to the suppression of the weak scale over the heavy mass scale. As a key feature of our construction, once the heavy Dirac fermion and doublet scalar go out of equilibrium, their decays induce the CP asymmetry from the interference of tree-level processes with the \textit{radiative vertex corrections} (rather than the self-energy corrections). Although there is no lepton number violation, an equal and opposite amount of CP asymmetry is generated in the left-handed and the right-handed neutrinos. The left-handed lepton asymmetry would then be converted to the baryon asymmetry in the presence of the sphalerons, while the right-handed lepton asymmetry remains unaffected.

description: We investigate the electronic states around a single vacancy in silicon crystal by using the Green's function approach. The triply degenerate vacancy states within the band gap are found to be extended over a large distance $\sim20 {\rm Å}$ from the vacancy site and contribute to the reciprocal temperature dependence of the quadrupole susceptibility resulting in the elastic softening at low temperture. The Curie constant of the quadrupole susceptibility for the trigonal mode ($O_{yz},O_{zx},O_{xy}$) is largely enhanced as compared to that for the tetragonal mode ($O_{2}^{0},O_{2}^{2}$). The obtained results are consistent with the recent ultrasonic experiments in silicon crystal down to 20 mK. We also calculate the dipole and octupole susceptibilities and find that the octupole susceptibilities are extremely enhannced for a specific mode.

description: The Orion Kleinmann-Low nebula (Orion KL) is notoriously complex and exhibits a range of physical and chemical components. We conducted high angular resolution (sub-arcsecond) observations of $^13$CH$_{3}$OH $ν=0$ ($\sim$0.3$^{\prime\prime}$ and $\sim$0.7$^{\prime\prime}$) and CH$_3$CN $ν_8=1$ ($\sim$0.2$^{\prime\prime}$ and $\sim$0.9$^{\prime\prime}$) line emission with the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate Orion KL's structure on small spatial scales (${\le}350$ au). Gas kinematics, excitation temperatures, and column densities were derived from the molecular emission via a pixel-by-pixel spectral line fitting of the image cubes, enabling us to examine the small-scale variation of these parameters. Sub-regions of the Hot Core have a higher excitation temperature in a 0.2$^{\prime\prime}$ beam than a 0.9$^{\prime\prime}$ beam, indicative of possible internal sources of heating. Furthermore, the velocity field includes a bipolar ${\sim}7{-}8$ km s$^{-1}$ feature with a southeast-northwest orientation against the surrounding ${\sim}4{-}5$ km s$^{-1}$ velocity field, which may be due to an outflow. We also find evidence of a possible source of internal heating toward the Northwest Clump, since the excitation temperature there is higher in a smaller beam versus a larger beam. Finally, the region southwest of the Hot Core (Hot Core-SW) presents itself as a particularly heterogeneous region bridging the Hot Core and Compact Ridge. Additional studies to identify the (hidden) sources of luminosity and heating within Orion KL are necessary to better understand the nebula and its chemistry.

description: The relation between the Wilson-Polchinski and the Litim optimized ERGEs in the local potential approximation is studied with high accuracy using two different analytical approaches based on a field expansion: a recently proposed genuine analytical approximation scheme to two-point boundary value problems of ordinary differential equations, and a new one based on approximating the solution by generalized hypergeometric functions. A comparison with the numerical results obtained with the shooting method is made. A similar accuracy is reached in each case. Both two methods appear to be more efficient than the usual field expansions frequently used in the current studies of ERGEs (in particular for the Wilson-Polchinski case in the study of which they fail).

Politics, unions, and the new middle class : a study of white-collar workers in Britain
Creators: name: Robbins, Allan R.
Publisher: name: University of British Columbia
Year: 2010

description: The thesis portrays the British white-collar worker in relation to four domains of analysis: the workplace, the trade union, the class system, and political life. Its empirical findings derive from in-depth interviews with 134 "staff employees of Midland Products", a large manufacturing corporation in Nottingham. At Midland, the broad evocation "the rise of white-collar work" obscures the cleavage in non-manual job types between light clerical positions and better-paid, highly-ranked, and supervisory positions. It also obscures a cleavage among the staff employees between women, who are more satisfied at work and less interested in promotion, and men, who are relatively dissatisfied and more ambitious. Moreover, men dominate the better, and women the most junior and poorest-paid jobs at the company. Nevertheless, women are much less likely than men voluntarily to affiliate with trade unions. Women are also more hostile to the power unions hold in British society. Midland's modal trade unionist is male, order, suggestively more senior in the hierarchy, but unlikely to subscribe to unionism's high principles. The staff employees are sharply divided by class identity; just 52% self-classifying as middle class. "Many believe themselves, and on the conventional measure are, upwardly mobile. But a middle or working class identity is a poor guide to staff employee views on workplace and social issues. Nor does it reflect the profound occupational inequalities they experience at the company. Most staff employees identify with and vote for the Conservative party. The Tory coalition includes virtually all those raised in Conservative homes, together with many raised by Liberals and Labourites. Inter-party migration is especially common among the sons and daughters of manually-employed Labourites who are subjectively mobile. Yet 30% of Midland's staff employees are Labourites, which is an important barrier to the normative coherence of the stratum. Owing primarily to the growth of non-manual Labourites, the outlook is for even more fragmentation in Britain's new middle class. Coupled with analogous changes in the industrial working class, the power of "the class dynamic" may be much attenuated in the 1980s.

description: LIN 358 and SMC N73 are two symbiotic binaries in the halo of the Small Magellanic Cloud, each composed of a hot white dwarf accreting from a cool giant companion. In this work, we characterize these systems using a combination of SED-fitting to the extant photometric data spanning a broad wavelength range (X-ray/ultraviolet to near-infrared), detailed analysis of the APOGEE spectra for the giant stars, and orbit fitting to high quality radial velocities from the APOGEE database. Using the calculated Roche lobe radius for the giant component and the mass ratio for each system, it is found that LIN 358 is likely undergoing mass transfer via wind Roche lobe overflow while the accretion mechanism for SMC N73 remains uncertain. This work presents the first orbital characterization for both of these systems (yielding periods of >270 and >980 days, respectively, for SMC N73 and LIN 358) and the first global SED fitting for SMC N73. In addition, variability was identified in APOGEE spectra of LIN 358 spanning 17 epochs over two years that may point to a time variable accretion rate as the product of an eccentric orbit.

description: The bispectrum is the leading non-Gaussian statistic in large-scale structure, carrying valuable information on cosmology that is complementary to the power spectrum. To access this information, we need to model the bispectrum in the weakly non-linear regime. In this work we present the first two-loop, i.e., next-to-next-to-leading order perturbative description of the bispectrum within an effective field theory (EFT) framework. Using an analytic expansion of the perturbative kernels up to $F_6$ we derive a renormalized bispectrum that is demonstrated to be independent of the UV cutoff. We show that the EFT parameters associated with the four independent second-order EFT operators known from the one-loop bispectrum are sufficient to absorb the UV sensitivity of the two-loop contributions in the double-hard region. In addition, we employ a simplified treatment of the single-hard region, introducing one extra EFT parameter at two-loop order. We compare our results to N-body simulations using the realization-based grid-PT method and find good agreement within the expected range, as well as consistent values for the EFT parameters. The two-loop terms start to become relevant at $k\approx 0.07h~\mathrm{Mpc}^{-1}$. The range of wavenumbers with percent-level agreement, independently of the shape, extends from $0.08h~\mathrm{Mpc}^{-1}$ to $0.15h~\mathrm{Mpc}^{-1}$ when going from one to two loops at $z=0$. In addition, we quantify the impact of using exact instead of Einstein-de-Sitter kernels for the one-loop bispectrum, and discuss in how far their impact can be absorbed into a shift of the EFT parameters.

description: This is a short or working paper that was written in response to a call for the RSE-HPC-2020 workshop (https://us-rse.org/rse-hpc-2020/) which will is part of the ACM and IEEE SC20 conference (https://sc20.supercomputing.org/). The paper argues that the terminology used to describe job related skills in computing and more specifically in research software engineering (RSE) is rapidly changing and that the terminology is not easily understood by people who work with RSEs such as HR professionals or policy makers. In deed the terminology is not necessarily understood by RSE in different specialisms. It goes on to argue that a framework that links skills to the RSE occupation is needed both for RSEs who wish to alter their career to fit the changing needs and for professionals who must interact with RSEs. Such a framework could be developed by combining knowledge gained from analysing job adverts using natural language processing (NPL), interviewing RSE specialist and building on known glossaries created by RSEs. As the computing technologies and the associated skills change rapidly this framework and its associated ontology the analysis would need to continue until a time when the changes are no longer so significant.

description: We investigate the properties of the dark matter (DM) halo surrounding the nearby galaxy group NGC 1600. Through the use of deep (252 ks) Chandra observations and 64.3 ks of XMM-Newton observations, we construct surface brightness profiles in multiple energy bands in order to perform hydrostatic equilibrium analysis of the hot plasma within NGC 1600. Regardless of the DM model profile assumed, we measure a halo concentration (c$_{200}$) that is an extreme, positive outlier of the $Λ$CDM c$_{200}$-M$_{200}$ relation. For a typical NFW DM profile, we measure c$_{200}\!=\!26.7\pm1.4$ and M$_{200}\!=\!(2.0\pm0.2)\times10^{13}$ M$_\odot$; assuming a similar halo mass, the average concentration expected is c$_{200}=6-7$ for the theoretical $Λ$CDM c-M relation. Such a high concentration is similar to that of well-known fossil groups MRK 1216 and NGC 6482. While NGC 1600 exhibits some properties of a fossil group, it fails to meet the X-ray luminosity threshold of L$_X>5\times10^{41}$ erg s$^{-1}$. Whether or not it is considered a fossil group, the high concentration value makes it part of a select group of galaxy groups.

description: We present a comparison of simulation-based inference to full, field-based analytical inference in cosmological data analysis. To do so, we explore parameter inference for two cases where the information content is calculable analytically: Gaussian random fields whose covariance depends on parameters through the power spectrum; and correlated lognormal fields with cosmological power spectra. We compare two inference techniques: i) explicit field-level inference using the known likelihood and ii) implicit likelihood inference with maximally informative summary statistics compressed via Information Maximising Neural Networks (IMNNs). We find that a) summaries obtained from convolutional neural network compression do not lose information and therefore saturate the known field information content, both for the Gaussian covariance and the lognormal cases, b) simulation-based inference using these maximally informative nonlinear summaries recovers nearly losslessly the exact posteriors of field-level inference, bypassing the need to evaluate expensive likelihoods or invert covariance matrices, and c) even for this simple example, implicit, simulation-based likelihood incurs a much smaller computational cost than inference with an explicit likelihood. This work uses a new IMNNs implementation in $\texttt{Jax}$ that can take advantage of fully-differentiable simulation and inference pipeline. We also demonstrate that a single retraining of the IMNN summaries effectively achieves the theoretically maximal information, enhancing the robustness to the choice of fiducial model where the IMNN is trained.

The development of cross language speech perception : the influence of age, experience, and context on perceptual organization
Creators: name: Werker, Janet
Publisher: name: University of British Columbia
Year: 2010

description: Previous research (Werker, Gilbert, Humphrey, & Tees, 1981) in which we compared English infants, English adults, and Hindi adults on their ability to discriminate two pairs of Hindi (non-English) speech contrasts indicated that infants without prior specific language experience can discriminate speech sounds according to phonetic categories, whereas adults may lose this ability as a function of either age and/or specific language experience. The present work was designed to answer several questions that emerged from that earlier research. First, experiments focussed on delineating the time course of the "decline" in non-native speech discrimination abilities across childhood. Second, experiments examined the generality of developmental change between infancy and adulthood by looking at cross-language speech perception of a new (Thompson, an Interior Salish Native Indian Language) non-English speech contrast. Third, speech perception performance was examined in relation to cognitive and linguistic development to try to determine why the decline occurred at one rather than another point in ontogeny. Finally, an attempt was made to clarify the nature and implications of the apparent loss of non-native speech perception abilities by varying both the discrimination procedure and the perceptual set conditions used in adult testing. The results of these experiments replicate our original findings (Werker, et. al., 1981) showing that infants can discriminate the universal set of phonetic contrasts, and that there is a decline in this ability as a result of specific linguistic experience. This decline occurs within the first year of life. The data tentatively support the notion that a certain level of memory development (enabling an early form of representational ability) may be necessary before specific experience can modify initial infant abilities. In addition, the results show a difference between phonetic and phonemic (meaning based) perception in adult subjects, with the phonemic being the most robust and the most easily demonstrated. It is suggested that phonemic perception may reflect the structuring of cognitive/perceptual categories. Speculation as to the form (prototypical) and the format (initially enactive, later symbolic) of the representation of these categories is offered.

description: Stripped-envelope supernovae (SE SNe) of Type Ib and Type Ic are thought to result from explosions of massive stars having lost their outer envelopes. The favoured explosion mechanism is by core-collapse, with the shock later revived by neutrino heating. However, there is an upper limit to the amount of radioactive Nickel-56 that such models can accomplish. Recent literature point to a tension between the maximum luminosity from such simulations and observations. We use a well characterized sample of SE SNe from the Zwicky Transient Facility (ZTF) Bright Transient Survey (BTS) to collect a sample of spectroscopically classified normal Type Ibc SNe for which we use the ZTF light curves to determine the maximum luminosity. We cull the sample further based on data quality, light-curve shape, distance and colors. The methodology of the sample construction from this BTS sample can be used for many other future investigations. In total we use 129 Type Ib or Type Ic BTS SNe with an initial rough luminosity distribution peaked at Mr = -17.61 +- 0.72, and where 36% are apparently brighter than the theoretically predicted maximum brightness of Mr = -17.8. When we further cull this sample to ensure that the SNe are normal Type Ibc with good LC data within the Hubble flow, the sample of 94 objects has Mr = -17.64 +- 0.54. A main uncertainty in absolute magnitude determinations for SNe is the host galaxy extinction correction, but the reddened objects only get more luminous after corrections. If we simply exclude objects with red, unusual or uncertain colors, we are left with 14 objects at M = -17.90 +- 0.73, whereof a handful are most certainly brighter than the suggested theoretical limit. The main result of this study is thus that normal SNe Ibc do indeed reach luminosities above $10^{42.6}$ erg/s, apparently in conflict with existing explosion models.

description: Non-axisymmetric oscillations of differentially rotating stars are studied using both slow rotation and Cowling approximation. The equilibrium stellar models are relativistic polytropes where differential rotation is described by the relativistic j-constant rotation law. The oscillation spectrum is studied versus three main parameters: the stellar compactness $M/R$, the degree of differential rotation $A$ and the number of maximun couplings $\ell_{\rm max}$. It is shown that the rotational splitting of the non-axisymmetric modes is strongly enhached by increasing the compactness of the star and the degree of differential rotation. Finally, we investigate the relation between the fundamental quadrupole mode and the corotation band of differentially rotating stars.

description: We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density $N_\mathrm{H\,I}\approx(1-3)\times10^{16}\,\mathrm{cm}^{-2}$ discovered at $z=0.5$ in the Cosmic Ultraviolet Baryon Survey (CUBS). Available far-ultraviolet spectra from the Hubble Space Telescope Cosmic Origins Spectrograph and optical echelle spectra from MIKE on the Magellan Telescopes enable a comprehensive ionization analysis of diffuse circumgalactic gas based on resolved kinematics and abundance ratios of atomic species spanning five different ionization stages. These data provide unambiguous evidence of kinematically aligned multi-phase gas that masquerades as a single-phase structure and can only be resolved by simultaneous accounting of the full range of observed ionic species. Both systems are resolved into multiple components with inferred $α$-element abundance varying from $[α/\text{H}]\approx\!{-0.8}$ to near solar and densities spanning over two decades from $\log n_\mathrm{H}\mathrm{cm}^{-3}\approx\!-2.2$ to $

description: In this paper, a new family of very-high-order TENO schemes with adaptive accuracy order and adaptive dissipation control (TENO-AA) is proposed. The new framework allows for constructing arbitrarily high-order TENO schemes in a unified paradigm and the yielded nonlinear schemes gradually reduce to low-order reconstructions by judging the smoothness with the ENO-like stencil selection strategy. In order to control the nonlinear numerical dissipation adaptively, the flow scales are first measured by examining the first-order undivided difference and the cut-off constant $C_T$ in the TENO weighting strategy is adapted based on the corresponding measurement. With one set of optimal parameters, the newly proposed TENO schemes are designed to deliver excellent performance for predicting highly compressible flows with a wide range of Mach numbers. While the new very-high-order TENO schemes feature good robustness for conventional gas dynamics, the ENO-property is well preserved with the assistant of a positivity-preserving flux limiter for extreme simulations. Without loss of generality, the typical eight- and ten-point TENO-AA schemes are constructed. A set of benchmark simulations are computed to demonstrate the performance of the proposed TENO schemes.

description: For an understanding of Galactic stellar populations in the SDSS filter system well defined stellar samples are needed. The nearby stars provide a complete stellar sample representative for the thin disc population. We compare the filter transformations of different authors applied to the main sequence stars from F to K dwarfs to SDSS filter system and discuss the properties of the main sequence. The location of the mean main sequence in colour-magnitude diagrams is very sensitive to systematic differences in the filter transformation. A comparison with fiducial sequences of star clusters observed in g',r',i' show good agreement. Theoretical isochrones from Padua and from Dartmouth have still some problems especially in (r-i)-colour.

description: Abstract— Soil organic matter content is a primary indicator of quality over measuring soil organic carbon (SOC). Demand has been created for quick and real time multiple analysis methods for SOC instead of available laborious, time consuming and expensive methods. There are developed Near Infrared Spectroscopy (NIR) methodologies for detecting SOC, however imply either expensive full scale NIR instruments or considerable work on sample preparation. There are attempt in narrow range vehicle mounted NIR detections in precision agriculture on the go mode SOC very low accuracy. This study develops a rapid method for the detection of SOC for laboratory scale. Soil samples(n=144) were collected from a range of sites at Mapalana research farm, University of Ruhuna in three different depths including 3 replicates from each depth. Seventy-two air-dried, sieved and finely ground soil samples were prepared in conventional dry sample presentation method. Four spectra per sample were taken by holding them into sample cups. Soil samples, saturated with distilled water were kept for 30min and similar process were followed for new wet sample presentation approach. Direct probe NIR Spectrometer FQANIR Gun (588-1100 nm) (Shibuya Seiki, Hamamatsu, Japan), was used to acquire NIR reflectance spectra. Standard Walkey-Black method was used to detect the organic carbon contents of spectra acquired soil samples as the respective reference data to validate the approach.
 For both wet and dry soil sample types, Partial Least Square (PLS) regression models were developed to predict the SOC. The validation results of both experiments were successful for the prediction of SOC where 0.95 of R2 and 0.248 of SEV for dry sample test and 0.91 of R2 and 0.245 of SEV for new wet sample approach. Sample preparation time and procedures were substantially reduced by the newly introduced wet method (30 min) when it is compared to the conventional spectroscopic methods (24 hrs). Average spectra investigation shows that 770 nm was strongly correlated with the SOC which could possibly be employed in further simplified instrumentation. The research revealed that the potential of using NIR technology as a nondestructive and rapid detection method for soil organic carbon with quick multiple field level detection facilities.
Particle heating and acceleration by reconnecting and non-reconnecting Current Sheets

description: In this article, we study the physics of charged particle energization inside a strongly turbulent plasma, where current sheets naturally appear in evolving large-scale magnetic topologies, but they are split into two populations of fractally distributed reconnecting and non-reconnecting current sheets (CS). In particular, we implement a Monte Carlo simulation to analyze the effects of the fractality and we study how the synergy of energization at reconnecting CSs and at non-reconnecting CSs affects the heating, the power-law high energy tail, the escape time, and the acceleration time of electrons and ions. The reconnecting current sheets (RCS) systematically accelerate particles and play a key role in the formation of the power-law tail in energy distributions. On the other hand, the stochastic energization of particles through their interaction with non-reconnecting CSs can account for the heating of the solar corona and the impulsive heating during solar flares. The combination of the two acceleration mechanisms (stochastic and systematic), commonly present in many explosive events of various sizes, influences the steady-state energy distribution, as well as the transport properties of the particles in position- and energy-space. Our results also suggest that the heating and acceleration characteristics of ions and electrons are similar, the only difference being the time scales required to reach a steady state.

description: We investigate geometrical properties of 5D cylindrical vacuum solutions with a transverse spherical symmetry. The metric is uniform along the fifth direction and characterized by tension and mass densities. The solutions are classified by the tension-to-mass ratio. One particular example is the well-known Schwarzschild black string which has a curvature singularity enclosed by a horizon. We focus mainly on geometry of other solutions which possess a naked singularity. The light signal emitted by an object approaching the singularity reaches a distant observer with finite time, but is infinitely red-shifted.

Street-Level Workers’ Discretion in the Changing Welfare

description: A crisis and deep re-organisation of European welfare systems started in the 1970s. Both the demand for and supply of welfare intervention are involved in relevant transformations, and the street-level workers are placed right at the crucial point where which they meet. They have to accomplish their complex mandate in a changing context and cope with multiple pressures. In order to carry out this task, they manage a certain degree of discretion (Lipsky 1980) that is shaped by the legal, organisational, cultural, social and economic context in which they are embedded. These conditions’ change tends to modify the “spaces” and the use of discretion. Usually, the street-level perspective studies the effects of discretion on policy implementation, services and users. This article focuses on how discretion produces feedback on the same street-level workers, modifying their role, work conditions and risks.

description: In order to explain the lack of carbon stars in the Galactic bulge, we have made a detailed study of thermal pulse - asymptotic giant branch stars by using a population synthesis code. The effects of the oxygen overabundance and the mass loss rate on the ratio of the number of carbon stars to that of oxygen stars in the Galactic bulge are discussed. We find that the oxygen overabundance which is about twice as large as that in the solar neighbourhood (close to the present observations) is insufficient to explain the rareness of carbon stars in the bulge. We suggest that the large mass loss rate may serve as a controlling factor in the ratio of the number of carbon stars to that of oxygen stars.

b\to sν\barν decay in the MSSM: Implication of b\to sγat large tan beta

description: The decay $b\to sν\barν$ is discussed in the minimal supersymmetric standard model with general flavor mixing for squarks, at large $\tanβ$. In this case, in addition to the chargino loop contributions which were analyzed in previously studies, $\tanβ$-enhanced contributions from the gluino and charged Higgs boson loops might become sizable compared with the standard model contribution, at least in principle. However, it is demonstrated that the experimental bounds on the new physics contributions to the radiative decay $b\to sγ$ should strongly constrain these contributions to $b\to sν\barν$, especially on the gluino contribution. We also briefly comment on a possible constraint from the $B_s\toμ^+μ^-$ decay.
