description: The present doctoral thesis is structured as a collection of three essays.
The first essay, “SOC(HE)-Italy: a classification for graduate occupations” presents the conceptual basis, the construction, the validation and the application to the Italian labour force of the occupational classification termed SOC(HE)-Italy. I have developed this classification under the supervision of Kate Purcell during my period as a visiting research student at the Warwick Institute for Emplyment Research. This classification links the constituent tasks and duties of a particular job to the relevant knowledge and skills imparted via Higher Education (HE). It is based onto the SOC(HE)2010, an occupational classification first proposed by Kate Purcell in 2013, but differently constructed. In the second essay “Assessing the incidence and wage effects of overeducation among Italian graduates using a new measure for educational requirements” I utilize this classification to build a valid and reliable measure for job requirements. The lack of an unbiased measure for this dimension constitutes one of the major constraints to achieve a generally accepted measurement of overeducation. Estimations of overeducation incidence and wage effects are run onto AlmaLaurea data from the survey on graduates career paths. I have written this essay and obtained these estimates benefiting of the help and guidance of Giovanni Guidetti and Giulio Pedrini. The third and last essay titled “Overeducation in the Italian labour market: clarifying the concepts and addressing the measurement error problem” addresses a number of theoretical issues concerning the concepts of educational mismatch and overeducation. Using Istat data from RCFL survey I run estimates of the ORU model for the whole Italian labour force. In my knowledge, this is the first time ever such model is estimated on such population. In addition, I adopt the new measure of overeducation based onto the SOC(HE)-Italy classification.
Involvement of DNA Methylation in Alcohol Withdrawal-Induced Behavioral Changes in Rats

description: Alcohol use disorder (AUD) poses a significant burden to global health and the economy. Individuals with AUD often self-medicate with alcohol to alleviate the negative affective symptoms of withdrawal, such as anxiety, which often results in a relapse to heavy drinking. The identification of novel therapeutic targets that can reduce withdrawal-induced increases in anxiety and drinking can help alleviate the burden of AUD. DNA methylation is an epigenetic mechanism that is dysregulated in AUD. Inhibitors of the enzymes that promote DNA methylation (DNMTs) have been used to treat certain forms of cancer, however their potential to treat symptoms of alcohol withdrawal is less understood. To address this gap, we used a rat model of alcohol dependence to explore the role of DNA methylation in both withdrawal-induced anxiety-like behavior and changes in alcohol drinking. We found that acute withdrawal produces subregion-specific increases in DNMT1 and DNMT3b protein and mRNA in the amygdala – a key region regulating anxiety. Systemic administration of the FDA-approved DNMT inhibitor, 5-azacytidine (5-AzaC), reversed the withdrawal-induced increase in anxiety-like behavior exhibited by these rats. Administration of 5-AzaC also reduced ethanol intake in a home cage drinking paradigm in both dependent and non-dependent rats. Taken together, these results suggest that DNA methylation is a potential therapeutic target to prevent relapse in AUD. In addition to heavy, uncontrolled drinking, significant time spent seeking out alcohol is also a common symptom of AUD, yet home cage drinking paradigms are unable to capture this behavior. Instead, operant ethanol self-administration paradigms are used to discriminate between appetitive (seeking) and consummatory (taking) behaviors. Curiously, however, most studies infer consumption indirectly from appetitive responding. To address this shortcoming, we compared operant behavior across three strains of outbred rats using a paradigm that directly measures both appetitive and consummatory behaviors. Our data uncovered three unique operant phenotypes and revealed that appetitive responding is correlated with consumption in only a subset of rats. These data suggest that direct measurement of consumption during operant self-administration is crucial. This approach will be useful for examining the effect of DNMT inhibition on both seeking and taking in the future.

description: We construct optical appearance and profiled spectral lines of Keplerian discs with inner edge at the innermost circular geodesic located on both sides of the reflection-symmetric Simpson-Visser wormhole, in dependence on its parameter and inclination angle of a distant observer. We demonstrate significant differences in appearance of the discs on the our side and the other side of the wormhole. Large part of the other-side disc is always in the dark region of the image of the disc orbiting on the our side, enabling thus a simple distinguishing in observations. The profiled spectral lines generated by the disc on the other side (our side) demonstrate strong (weak) dependence on the spacetime parameter, and weak (strong) dependence on the inclination angle; they have also different shape, giving thus other clues to clearly distinguish in observations reflection-symmetric wormholes as alternatives to black holes.

description: The purpose of this study was to look into the role of emotional intelligence in effective leadership and the mediating effects of different leadership styles on the relationship between emotional intelligence and organizational performance, in order to provide insights for organizations looking to improve leadership effectiveness. Methodology: A cross - sectional study approach was used, and data were gathered from 531 managers in the Uttarakhand state of manufacturing sector using self - report measures and judgemental sampling. The predicted links between emotional intelligence, leadership styles (transformational, transactional, and laissez - faire), and organizational success were tested using structural equation modeling. Findings: The findings demonstrated that emotional intelligence affects organizational performance favorably, with transformational leadership acting as a strong mediator in this connection. According to the research, transformational leaders with greater emotional intelligence are more likely to produce superior organizational performance, but the moderating impacts of transactional and laissez - faire leadership styles are less evident. Implications: The results imply that firms should emphasize emotional intelligence and transformational leadership development in their managers via training programs, coaching, and mentoring. Furthermore, the findings highlight the importance of organizations considering emotional intelligence as a critical factor when selecting and promoting managers. The cross - sectional design, use of self - report measures, context - specific findings, judgmental sampling approach, and unexplored variables that could influence the relationships between emotional intelligence, leadership styles, and organizational performance are all limitations of this study.

description: We study the effective dynamics of two mirrors, forming an optical cavity, and interacting with the cavity field via radiation pressure. We pursue a perturbative influence functional approach to trace out the degrees-of-freedom of the field, and obtain the second order effective action for the system composed by the mirrors. We find that the interaction between the mirrors is mediated by pairs of field modes, which combine in such a way to give rise to two different interaction channels. We find that the quantum and thermal fluctuations of the cavity field result in coloured, Gaussian stochastic noises acting on the mirrors. To each of these noises is associated a dissipative effect, and the corresponding power spectra and susceptibilities are related via generalized fluctuation-dissipation relations. We finally demonstrate that the dynamics of the mirrors admits a stochastic interpretation, and give the relative quantum Langevin equations.

description: By means of high resolution hydrodynamical, three-dimensional calculations with nested-meshes, we evaluate the eccentricity reached by a low-mass, luminous planet embedded in an inviscid disc with constant thermal diffusivity and subjected to thermal forces. We find that a cell size of at most one tenth of the size of the region heated by the planet is required to get converged results. When the planet's luminosity is supercritical, we find that it reaches an eccentricity of order $10^{-2}$--$10^{-1}$, which increases with the luminosity and broadly scales with the disc's aspect ratio. Restricting our study to the case of pebble accretion, we incorporate to our model the dependence of the accretion rate of pebbles on the eccentricity. There is therefore a feedback between eccentricity, which determines the accretion rate and hence the planet's luminosity, and the luminosity, which yields the eccentricity attained through thermal forces. We solve for the steady state eccentricity and study how this quantity depends on the disc's turbulence strength parameter $α_z$, on the dimensionless stopping time of the pebbles $τ_s$, on the inward mass flux of pebbles and on the headwind (the difference between the gas velocity and the Keplerian velocity). We find that in general low-mass planets (up to a few Earth masses) reach eccentricities comparable to the disc's aspect ratio, or a sizeable fraction of the latter. Eccentric, low-mass protoplanets should therefore be the norm rather than the exception, even if they orbit far from other planets or from large scale disturbances in the disc.

The Pilot's Daughter

description: The Pilot’s Daughter rides the prosperity gospel movement across the Texas panhandle to follow my family’s quest for a faith healer to save my father’s life. In 1997, my father, a healthy thirty-eight-year-old pilot, was diagnosed with stage IV cancer. He rejected medical dictum, joining my mother, a woman of spitfire and brimstone, in seeking divine intervention from such drifters as a traveling evangelist, a Romanian anti-communist huckster, and a local prophet who led services called “Miracles on 34th Street.” How did two white, college-educated adults come to plead holy for a miracle? I trace my family’s history and discover that my father, like thousands of military pilots, consumed drinking water tinctured by carcinogens from military-grade fire-fighting foams. Though we believed faith could earn my father’s survival, toxic water had already determined his fate. What I didn’t realize at the time was that my family was part of a sea-change in how over 40 million American evangelicals have come to view science as the devil even as the landscapes we call home erode and with them, our lives.

description: The Panoramic SETI (Search for Extraterrestrial Intelligence) experiment (PANOSETI) aims to detect and quantify optical transients from nanosecond to second precision over a large field-of-view ($\sim$4,450 square-degrees). To meet these challenging timing and wide-field requirements, the PANOSETI experiment will use two assemblies of $\sim$45 telescopes to reject spurious signals by coincidence detection, each one comprising custom-made fast photon-counting hardware combined with ($f/1.32$) focusing optics. Preliminary on-sky results from pairs of PANOSETI prototype telescopes (100 sq.deg.) are presented in terms of instrument performance and false alarm rates. We found that a separation of $>$1 km between telescopes surveying the same field-of-view significantly reduces the number of false positives due to nearby sources (e.g., Cherenkov showers) in comparison to a side-by-side configuration of telescopes. Design considerations on the all-sky PANOSETI instrument and expected field-of-views are reported.

description: Temporal difference (TD) learning and its variants, such as multistage TD (MS-TD) learning and temporal coherence (TC) learning, have been successfully applied to 2048. These methods rely on the stochasticity of the environment of 2048 for exploration. In this paper, we propose to employ optimistic initialization (OI) to encourage exploration for 2048, and empirically show that the learning quality is significantly improved. This approach optimistically initializes the feature weights to very large values. Since weights tend to be reduced once the states are visited, agents tend to explore those states which are unvisited or visited few times. Our experiments show that both TD and TC learning with OI significantly improve the performance. As a result, the network size required to achieve the same performance is significantly reduced. With additional tunings such as expectimax search, multistage learning, and tile-downgrading technique, our design achieves the state-of-the-art performance, namely an average score of 625 377 and a rate of 72% reaching 32768 tiles. In addition, for sufficiently large tests, 65536 tiles are reached at a rate of 0.02%.

description: The electronic states of lateral many electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb blockade peaks are measured. A zig-zag pattern is found as it is known from the Fock-Darwin spectrum. However, only data from Landau level 0 show the typical spin-induced bimodality, whereas features from Landau level 1 cannot be explained with the Fock-Darwin picture. Instead, by including the interaction effects within spin-density-functional theory a good agreement between experiment and theory is obtained. The absence of bimodality on Landau level 1 is found to be due to strong spin polarization.

description: We investigate the vortex-lattice structure for single- and two-component Bose-Einstein condensates in the presence of an optical lattice, which acts as a pinning potential for the vortices. The problem is considered in the mean-field quantum-Hall regime, which is reached when the rotation frequency $Ω$ of the condensate in a radially symmetric trap approaches the (radial) trapping frequency $ω$ and the interactions between the atoms are weak. We determine the vortex-lattice phase diagram as a function of optical-lattice strength and geometry. In the limit of strong pinning the vortices are always pinned at the maxima of the optical-lattice potential, similar to the slow-rotation case. At intermediate pinning strength, however, due to the competition between interactions and pinning energy, a structure arises for the two-component case where the vortices are pinned on lines of minimal potential.
Unsteady mass transfer from a core-shell cylinder in crossflow

description: Mass transfer from a composite cylinder - made of an inner core and an outer enveloping semipermeable shell - under channel crossflow is studied numerically using two-dimensional lattice-Boltzmann simulations. The core is initially loaded with a solute that diffuses passively through the shell towards the fluid. The cylinder internal structure and the initial condition considered in this study differ and thus complement the classical studies dealing with homogeneous uncoated cylinders whose surfaces are sustained at either constant concentration or constant mass flux. Here, the cylinder acts as a reservoir endowed with a shell that controls the leakage rate of the encapsulated solute. The transition from steady to unsteady laminar flow regime, around the cylinder, alters the released solute spatial distribution and the mass transfer efficiency, which is characterized by the Sherwood number (the dimensionless mass transfer coefficient). Moreover, the reservoir involves unsteady and continuous boundary conditions, which lead to unsteady and nonuniform distribution of both the concentration and the mass flux at the cylinder surface. The effect of adding a coating shell is highlighted, for a given ratio of the cylinder diameter to the channel width, by extracting a correlation from the computed data set. This new correlation shows explicit dependency of the Sherwood number upon the shell solute permeability (the shell mass transfer coefficient).

description: The purpose of this study was to examine the effects of different coaching styles on elementary school age girls, who were involved in a competitive basketball program. The study was concerned with effects of athletics and coaching styles upon the emotional, personality, and character development of girls. A comparison of girls who were not involved in competitive athletics with those who were was also undertaken. The sample included thirty-two participants and fourteen non-participants. The groups studied consisted of Grade VII girls attending Catholic elementary schools, in the Greater Vancouver area of British Columbia, Canada. The thirty-two participants were divided into three selected groups. Group I girls were exposed to a non-aggressive, "easy-going" coach for a period of approximately 3-1/2 months. Group III girls were exposed to an aggressive and autocratic coach, while Group II girls were exposed to a coach who fell between these two extremes. A control group of non-participants was selected from each school. This study was designed to investigate hypotheses based on the following five problems: I. changes in personality characteristics of participants as elicited by different coaching styles, II. changes in sportsmanship attitudes of participants as elicited by different coaching styles, III. changes in the self-concept of participants as elicited by different coaching styles, I.V. differences in attitude of the players toward their coach as elicited by respective coaching styles, V. differences in sportsmanship and personality between participants and non-participants. A 3 X 2 multivariate analysis of variance was performed on the fourteen personality variables as well as the two attitude variables to test hypotheses I, II, III and IV. Hypothesis V was tested by a 2 X 2 multivariate analysis of variance on the same dependent variables with the exception of attitude toward the coach, to test the differences between the changes elicited in the participants (from all schools) and the non-participants (also from all schools). The empirical findings were not in agreement with the predicted hypotheses. The differences among the three coaching styles, in the changes elicited in personality characteristics including self-concept and sportsmanship attitudes were found to be non-significant, at the .05 level. It was also predicted that there would be differences among the three coaching styles in the attitude of the players toward their coach. The differences in the attitude of the players was found to be non-significant at the .05 level. Finally, the differences between the participants and non-participants in personality and sportsmanship attitudes were once again non-significant at the .05 level.

description: We discuss a gauge-invariant prescription to take the mean-field approximation self-consistently in the PNJL model (Nambu--Jona-Lasinio model with the Polyakov loop). We first address the problem of non-vanishing color density in normal quark matter, which is an artifact arising from gauge-fixed treatment of the Polyakov loop mean-fields. We then confirm that the gauge average incorporated in our prescription resolves this problem and ensures color neutrality. We point out that the proposed method has an advantage in computing the expectation value of any function of the Polyakov loop matrix. We discuss the Casimir scaling as an immediate application of the method.

description: Models for the formation and evolution of galaxies readily predict physical properties such as the star formation rates, metal enrichment histories, and, increasingly, gas and dust content of synthetic galaxies. Such predictions are frequently compared to the spectral energy distributions of observed galaxies via the stellar population synthesis (SPS) technique. Substantial uncertainties in SPS exist, and yet their relevance to the task of comparing galaxy evolution models to observations has received little attention. In the present work we begin to address this issue by investigating the importance of uncertainties in stellar evolution, the initial stellar mass function (IMF), and dust and interstellar medium (ISM) properties on the translation from models to observations. We demonstrate that these uncertainties translate into substantial uncertainties in the ultraviolet, optical, and near-infrared colors of synthetic galaxies. Aspects that carry significant uncertainties include the logarithmic slope of the IMF above 1 Msun, dust attenuation law, molecular cloud disruption timescale, clumpiness of the ISM, fraction of unobscured starlight, and treatment of advanced stages of stellar evolution including blue stragglers, the horizontal branch, and the thermally-pulsating asymptotic giant branch. The interpretation of the resulting uncertainties in the derived colors is highly non-trivial because many of the uncertainties are likely systematic, and possibly correlated with the physical properties of galaxies. We therefore urge caution when comparing models to observations.

description: We examine phylogenetic relationships among species and populations of Asian cavity-nesting honeybees, emphasizing detection of potential unrecognized species in the geographically widespread Apis cerana Fabricius (Hymenoptera, Apidae). We carried out a phylogenetic analysis of genome-wide single nucleotide polymorphisms (SNPs) using BEASTv1.8.4 and IQ-TREE 2. Our samples cover the largest geographic area and number of populations of Asian cavity-nesting honeybees sampled to date. Nodes in the tree were calibrated using the mid-Miocene giant honeybee Apis lithohermaea Engel. We used STRUCTURE, Bayes Factor Delimitation, and discriminant analysis of principal components to infer probable species among populations of cavity-nesting honeybees currently recognized as Apis cerana. Our results support four species within A. cerana: the yellow "plains" honeybee of India and Sri Lanka; the lineage inhabiting the oceanic Philippine islands; the Sundaland lineage found in Indonesia, Malaysia and parts of southeast Asia; and a Mainland lineage, which we provisionally consider A. cerana in a narrow sense.

description: Este trabalho surge durante a elaboração de um curta-metragem de animação baseada na música Ponta de Areia de Milton Nascimento e Fernando Brant, que faz referência ao fim das ferrovias no Brasil. A pesquisa que envolve trem e cinema desemboca na ligação entre duas máquinas — a Locomotiva e o Cinematógrafo — e como ambas foram força motriz e representantes da modernidade. Assim, tenho como objetivo descrever como a pesquisa bibliográfica sobre o tema possibilitou a formação de tendências para o meu percurso artístico, as quais influenciaram escolhas no meu processo de criação. Com base na noção moderna de progresso e deslocamento, tento emular, na estrutura linear do texto, uma estrada de ferro, enquanto demonstro como a paisagem e sensibilidade modernas — vaporosas, em que cidades se desfazem e se refazem do dia para a noite, marcadas pelo signo da ruína — influenciaram na construção conceitual do curta-metragem.

description: Poverty and low economic status have been demonstrated to have deleterious effects on children’s emotional development, particularly internalizing symptoms, and may differ between males and females. Although this relationship has been consistently demonstrated, explanations for its existence have been sparsely explored. The current study examined, distress tolerance, as a mediator underlying the relationship between multiple childhood poverty-related adversity metrics and trait anxiety. Based on the available data from the Chicago School Readiness Project, the current study consisted of a sample of adolescents living in high-poverty, Chicago neighborhoods (N=309) measured between the ages of 3 and 16. Childhood Individual-level indicators of poverty (household poverty, perceived financial hardship, exposure to violence) and structural-level indicators (neighborhood poverty, neighborhood wealth inequality) were measured via self-report or U.S. Census data. Distress tolerance was measured behaviorally at age 15 and adolescent trait anxiety was measured at age 16 via self-report questionnaire. Results of the 5 mediation models and Bias Corrected and Accelerated bootstrapping analyses were not significant and, as such, the moderating effect of gender was not explored. However, the current study demonstrated that distress tolerance has varying relationships across subjective and objective measures of childhood poverty. Specifically, subjective measures of childhood poverty (perceived financial hardship, exposure to violence) were related to increased adolescent trait anxiety. Additionally, objective indicators of poverty (household poverty, neighborhood poverty, neighborhood wealth inequality) were negatively associated with distress tolerance. This new evidence supports targeted intervention at the individual-level to treat persistent anxiety, as well as enacting structural change to increase adolescent distress tolerance, all in an effort to minimize the negative impact of childhood poverty.

description: In the United States, dementia affects 14% of older adults, with another 15-20% exhibiting mild cognitive impairment (MCI), a prodrome to dementia. Moreover, African Americans have a higher incidence of dementia than other racial groups. One contributor to dementia may be the gut microbiota since it may reduce the systemic inflammation and oxidative stress that contributes to dementia. Moreover, a Mediterranean Diet and intentional weight loss (IWL) may decrease dementia risk by improving the gut microbiota’s ability to produce anti-inflammatory molecules and prevent oxidative stress. However, no study has characterized the differences in the gut microbiota of African Americans with or without MCI or characterized the role the gut microbiota has in connecting a Mediterranean Diet and IWL to cognition. First, we conducted a case-control study of predominately older, obese, African American adults to characterize the gut microbiota of 30 individuals with and 30 without MCI, matched on age, sex, and BMI. Those with MCI had higher levels of microbiota associated with cognitive decline, i.e., Dialister invisus. These relationships were dependent on levels of bacterial translocation, systemic inflammation, or oxidative stress. Second, within the context of an 8-month Randomized Controlled Trial (RCT) called the Building Research in Diet and Cognition (BRIDGE) trial, we tested the cognitive and microbial effect of a Mediterranean Diet with (MedWL) or without IWL (MedA), compared to controls, in a subsample of participants highly adherent to their intervention assignment. Results did not reveal a large shift to the gut microbiota in MedA, MedWL, or controls. However, in the MedA group, M. massilensies increased and was negatively associated with changes to memory performance, independent of changes to inflammation and oxidative stress. Also, an increase in Mediterranean Diet adherence was significantly correlated with an increase in butyrate production potential. These data suggest that an 8-month Mediterranean Diet intervention can induce changes to the gut microbiota that relate to cognition. Future studies in this field should include measurement of several microbial metabolites and functions and larger cohorts with more frequent stool sampling to describe more fully the relationship between the gut microbiota and cognition.

description: We investigate simple models for strictly non-ergodic stochastic processes $x_t$ ($t$ being the discrete time step) focusing on the expectation value $v$ and the standard deviation $δv$ of the empirical variance $v[x]$ of finite time series $x$. $x_t$ is averaged over a fluctuating field $σ_{r}$ ($r$ being the microcell position) characterized by a quenched spatially correlated Gaussian field. Due to the quenched field $δv(Δt)$ becomes a finite constant, $Δ_{ne} > 0$, for large sampling times $Δt$. The volume dependence of the non-ergodicity parameter $Δ_{ne}$ is investigated for different spatial correlations. Models with marginally long-ranged $\fr$-correlations are successfully mapped on shear-stress data from simulated amorphous glasses of polydisperse beads.

description: The Hirsch conjecture was posed in 1957 in a letter from Warren M. Hirsch to George Dantzig. It states that the graph of a d-dimensional polytope with n facets cannot have diameter greater than n - d. Despite being one of the most fundamental, basic and old problems in polytope theory, what we know is quite scarce. Most notably, no polynomial upper bound is known for the diameters that are conjectured to be linear. In contrast, very few polytopes are known where the bound $n-d$ is attained. This paper collects known results and remarks both on the positive and on the negative side of the conjecture. Some proofs are included, but only those that we hope are accessible to a general mathematical audience without introducing too many technicalities.

description: We discuss the inhomogeneous pion condensed phase within the framework of chiral perturbation theory. We show how the general expression of the condensate can be obtained solving three coupled differential equations, expressing how the pion fields are modulated in space. Upon using some simplifying assumptions, we determine an analytic solution in (3+1)-dimensions. The obtained inhomogeneous condensate is characterized by a non-vanishing topological charge, which can be identified with the baryonic number. In this way, we obtain an inhomogeneous system of pions hosting an arbitrary number of baryons at fixed positions in space.

description: We investigate the broad line profiles emitted from a system supermassive binary black hole (SMBBH) having elliptical orbits and low mass ratio of $m_2/m_1\sim 0.1$. Our model assumes a super Eddington accretion flow in the case of a smaller component, whereas the massive component has very small or negligible accretion, therefore supposing that no broad line region (BLR) is attached to it. Thus, the proposed SMBBH system contains one moving BLR, associated with the less massive component and one circum-binary BLR. We study the effect of different total mass of the system (ranging from 10$^6$ to 10$^8$ Solar masses) to the $\mathrm{Hβ}$ line profiles and to the continuum and line light curves. The resulted broad line profiles are asymmetric and shifted, and are varying during the orbital period. The asymmetry in the broad line profiles is discussed in terms of expected differences between the proposed model of the SMBBH with one active component and the scenario of a recoiling black hole. We discuss the periodicity detected in the line and continuum light curves, as well as in the variations of the line asymmetry and shift.

description: The review is focused on one of the most exotic families of iron-based superconductors belonging to the AFeAs structural type, where A is alkali metal. We briefly concern physical and electron properties of the typical members of this family, LiFeAs and NaFeAs, discuss the theoretical models describing the multiple-gap superconducting state, and the experimental data available in literature. As well, we specify the main unsolved problems, that seem crucial for both the AFeAs family and for iron-based superconductors in general.

description: We analyze a competitive labor market in which workers signal their productivities through education à la Spence (1973), and firms have the option of auditing to learn workers’ productivities. Audits are costly and non–contractible. We characterize the trade–offs between signaling by workers and costly auditing by firms. Auditing is always associated with (partial) pooling of worker types, and education is used as a signalonly if relatively few workers have low productivity. Our results feature new auditingpatterns and explain empirical observations in labor economics like wage differentialsand comparative statics of education choices. Our analysis applies also to other signalingproblems, e.g., the financial structure of firms, warranties, and initial public offerings.
