description: Considerable interest is now focused on the detection of terrestrial mass planets around M dwarfs, and radial velocity surveys with high-resolution spectrographs in the near infrared are expected to be able to discover such planets. We explore the possibility of using commercially available molecular absorption gas cells as a wavelength reference standard for high-resolution fiber-fed spectrographs in the near-infrared. We consider the relative merits and disadvantages of using such cells compared to Thorium-Argon emission lamps and conclude that in the astronomical H band they are a viable method of simultaneous calibration, yielding an acceptable wavelength calibration error for most applications. Four well-characterized and commercially available standard gas cells of HCN, 12C$_2$H$_2$, 12CO, and 13CO can together span over 120nm of the H band, making them suitable for use in astronomical spectrographs. The use of isotopologues of these molecules can increase line densities and wavelength coverage, extending their application to different wavelength regions.

Unfinished Writings / Interrupted Communities in Postdictatorship Latin America
Creators: name: Campo Becerra, Oscar Daniel
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: My dissertation examines a set of Latin American novels from the last decades of the twentieth century that strategically interrupt, avoid, or block narrative closure. I argue that what I call “unfinished novels” challenge fundamental assumptions of cultural belonging and collective social subject in the decline of the national-popular state. Rather than the totalizing novel of the Latin American Boom novel during the sixties, where the social, ethnic, and economic divisions integrate in a harmonic form, I demonstrate that the formal “failure” of the unfinished novels makes visible the entanglement between violence and history in Latin American postcolonial states. I analyze the disrupted communities portrayed in these novels to understand how the entry of transnational capital modifies the ways of “being together” in the aftermath of Latin American dictatorships. Through the reading of José María Argueda’s El zorro de arriba y el zorro de abajo and Clarice Lispector’s A hora da estrella, I show how the un-finishing formal mechanisms work, the aesthetics and political implications of them, and put into question what I called the paradigm of the “literature outside itself” (literatura fuera de sí), a predominant way of reading novels within Latin American Studies.

description: Aims: Psychologically informed environments (PIE) is a broad and flexible framework developed in UK homelessness services. PIE integrates psychologically informed ideas and approaches into service design to consider the psychological and emotional needs of service-users and staff. This study aimed to explore how psychological professionals interpret and implement PIE and what this looks like in practice.

Methodology: Semi-structured interviews were conducted with 11 practitioner psychologists who use a PIE approach in homelessness services or organisations. Reflexive thematic analysis was used to explore how PIE is applied in practice.

Results: Five themes were identified through the thematic analysis: (1) ‘PIE is a journey, not a destination’ which describes how practitioner psychologists deciphered and implemented PIE over time. (2) ‘Building trusting relationships’ which describes the importance and process of building trust with people experiencing homelessness and with colleagues. (3) ‘Systemic barriers to PIE’ which describes systemic, structural, and societal barriers to the implementation of PIE. (4) ‘Reluctance from staff teams’ which describes some staff teams’ discomfort with reflective practice sessions and the judgemental attitudes held towards service-users, and (5) ‘The enormity of PIE’ which describes PIE as a vast framework which can be utilised by professionals and services irrespective of formal psychological training and is challenging for a single staff member to hold and manage in their day-to-day workload.

Conclusions: This research explored the accounts of practitioner psychologists using PIE in homelessness services. The time required to decipher and implement PIE should be acknowledged by senior leaders, commissioners, and psychological professionals. Building trusting relationships with both service-users and other staff is a cornerstone of PIE and should be emphasised. Consideration should be given to policies and initiatives to reduce systemic limitations, engage staff teams, and share the responsibility of implementing PIE.
Time-resolved spectroscopy of the planet-hosting sdB pulsator V391 Pegasi

description: The subdwarf B (sdB) star V391 Peg oscillates in short-period p modes and long-period g modes, making it one of the three known hybrids among sdBs. As a by-product of the effort to measure secular period changes in the p modes due to evolutionary effects on a time scale of almost a decade, the O-C diagram has revealed an additional sinusoidal component attributed to a periodic shift in the light travel time caused by a planetary-mass companion around the sdB star in a 3.2 yr orbit. In order to derive the mass of the companion object, it is necessary to determine the orbital inclination. One promising possibility to do this is to use the stellar inclination as a primer for the orbital orientation. The stellar inclination can refer to the rotational or the pulsational axis, which are assumed to be aligned, and can in turn then be derived by combining measurements of v_(rot) and v_(rot)sin i. The former is in principle accessible through rotational splitting in the photometric frequency spectrum (which has however not been found for V391 Peg yet), while the projected rotational velocity can be measured from the rotational broadening of spectral lines. The latter must be deconvolved from the additional pulsational broadening caused by the surface radial velocity variation in high S/N phase averaged spectra. This work gives limits on pulsational radial velocities from a series of phase resolved spectra. Phase averaged and phase resolved high resolution echelle spectra were obtained in May and September 2007 with the 9m-class Hobby-Eberly Telescope (HET), and one phase averaged spectrum in May 2008 with the 10m-Keck 1 telescope.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Spin Hall effect at finite wave vector in a ferromagnetic conductor is theoretically studied by calculating the spin density as the linear response to an applied electric field. The cases of a spin-orbit interaction due to random impurities and a localized Rashba interaction are considered. It is shown that the spin Hall effect has a broad response for the wave vector $q\lesssim 2\kf$ where $\kf $ is the Fermi wave vector. This fact confirms the local nature of the spin-charge conversion effects.

description: A central problem in quantum condensed matter physics is the critical theory governing the zero temperature quantum phase transition between strongly renormalized Fermi-liquids as found in heavy fermion intermetallics and possibly high Tc superconductors. We present here results showing that the mathematics of string theory is capable of describing such fermionic quantum critical states. Using the Anti-de-Sitter/Conformal Field Theory (AdS/CFT) correspondence to relate fermionic quantum critical fields to a gravitational problem, we compute the spectral functions of fermions in the field theory. By increasing the fermion density away from the relativistic quantum critical point, a state emerges with all the features of the Fermi-liquid.

description: We show how the constant curvature spacetimes of 3d gravity and the associated symmetry algebras can be derived from a single quantum deformation of the 3d Lorentz algebra sl(2,R). We investigate the classical Drinfel'd double of a "hybrid" deformation of sl(2,R) that depends on two parameters (η,z). With an appropriate choice of basis and real structure, this Drinfel'd double agrees with the 3d anti-de Sitter algebra. The deformation parameter ηis related to the cosmological constant, while z is identified with the inverse of the speed of light and defines the signature of the metric. We generalise this result to de Sitter space, the three-sphere and 3d hyperbolic space through analytic continuation in ηand z; we also investigate the limits of vanishing ηand z, which yield the flat spacetimes (Minkowski and Euclidean spaces) and Newtonian models, respectively.

description: Open-ended questions test a more thorough understanding than closed-ended questions and are often a preferred assessment method. However, open-ended questions are tedious to grade and subject to personal bias. Therefore, there have been efforts to speed up the grading process through automation. Short Answer Grading (SAG) systems aim to automatically score students' answers. Despite growth in SAG methods and capabilities, there exists no comprehensive short-answer grading benchmark across different subjects, grading scales, and distributions. Thus, it is hard to assess the capabilities of current automated grading methods in terms of their generalizability. In this preliminary work, we introduce the combined ASAG2024 benchmark to facilitate the comparison of automated grading systems. Combining seven commonly used short-answer grading datasets in a common structure and grading scale. For our benchmark, we evaluate a set of recent SAG methods, revealing that while LLM-based approaches reach new high scores, they still are far from reaching human performance. This opens up avenues for future research on human-machine SAG systems.

Ordered magnetic systems studied by nuclear orientation

description: The antiferromagnetic and spin-flop phases of MnCl‧4H₂O have been investigated by observing the nuclear orxentatxon of ⁵⁴Mn in that material. The sublattice magnetizations in the absence of an external field were found to lie in a direction between the a and c crystal axes at an angle of 11.5° ± 3.5° to the c axis. The field dependence of the spin configuration in the spin-flop state indicates that second order anisotropy is significant in this system. The molecular fields were determined by combining the results of this work with other measurements of the-critical fields (Rives and Benedict, 1975). The results are: the exchange field is 11.05 ± 0.21 KOe; the biaxial single ion anisotropy fields are 0.75 ± 0.22 KOe and 2.35 ± 0.23 KOe along the a* and b axes respectively; the second order anisotropy field is 1.45 ± 0.19 KOe and the anisotropic exchange field is 0.1 ± 0.3 KOe. The spin-flop transition region was found to be adequately described by a 'domain' structure in which regions of antiferromagnetic phase and regions of spin-flop phase co-exist in the crystal. Measurements were made of the temperature dependence of the spin-flop transition field and, contrary to the extrapolated results of Rives and Benedict (1975) , the spin-flop field was found to decrease with decreasing temperature from 0.3K to 0.15K. If there is a minimum in the transition field it must occur at lower temperatures. The cooling of the MnCl‧4H₂O crystal which was held in contact with a copper heat sink by Apiezon N grease was fitted to the relation Q = kA (T₁ⁿ-T₂ⁿ) where T₁ and T₂ are the temperatures of the crystal and copper heat sink respectively, and A is the contact area. For n = 4 the value obtained for the constant k is (8.2 ± 1.9) x 10³ ergK⁻⁴ sec⁻¹ cm⁻². Nuclear orientation experiments were also performed on the systems ¹⁰³Ru-Fe and ⁵⁹Fe-Fe. The gamma-ray anisotropies for these systems (at temperatures of 10 and 15 mK, respectively) were very small; however, it was possible to determine limits for the magnitudes of the nuclear magnetic moments of the active nuclei. The ¹⁰³Ru moment was found to be greater than 0.15uN and the ⁵⁹Fe moment was found to be less than 0.9uN. J.E. Rives and V. Benedict, Phys. Rev. B12, 1908 (1975).

description: A rotational band with five $γ$-ray transitions ranging from 2$^{+}$ to 12$^{+}$ states was identified in $^{40}$Ar. This band is linked through $γ$ transitions from the excited 2$^{+}$, 4$^{+}$ and 6$^{+}$ levels to the low-lying states; this determines the excitation energy and the spin-parity of the band. The deduced transition quadrupole moment of 1.45$^{+0.49}_{-0.31} eb$ indicates that the band has a superdeformed shape. The nature of the band is revealed by cranked Hartree--Fock--Bogoliubov calculations and a multiparticle--multihole configuration is assigned to the band.
Export-Oriented Porcelain Economy in Song-Yuan China: Production Strategies, Interactions, and Networks

description: Export-oriented mass production is often associated with modern western economies, but similar production systems had already developed in southeast China prior to the modern era. So far, little is known about how large-scale, nonelite production system was organized at the local level to meet the global demands in the premodern period. This dissertation examines the large-scale porcelain production of the Song and Yuan dynasties (960–1368 CE) at Dehua, Fujian, China, where dozens of huge “dragon” kilns produced enormous amounts of porcelains for export. Rather than merely looking at porcelain products from the few “representative” kiln sites, this research aims at examining the production strategies, technological interactions, and production networks at Dehua at the micro level. A combination of multidisciplinary methods—spatial analysis, stylistic analysis, compositional analysis (LA-ICP-MS and pXRF), and social network analysis—were used in this research. Results show that there were two distinct production communities at Dehua—Gaide and Longxun-Sanban, which had different ceramic-making traditions and used local clays for production. Within the same production subregion, there were extensive technological interactions among potters, especially among those in the same village. Each kiln at Dehua might be jointly owned by multiple families or workshops, which produced homogeneous products for overseas markets. The research demonstrates that analyzing large-scale porcelain production at the micro level provides a fine-grained perspective on production organization and interaction within the same production region. It also shows that pXRF is capable of finding compositional patterning within a small region of ceramic production. The identification of two production subregions at Dehua also provides criteria to help more precisely source Dehua wares from shipwrecks or land sites outside China.

description: We investigated the behavioural and oxidative stress responses in the earthworm, Nsukkadrilus mbae on exposure to lead (Pb) and cadmium (Cd) contaminated soils. This was because the response of this species to heavy metals ecotoxicity had not been reported. Two concentrations of Pb (20 and 500 µg/g of soil) and Cd (2 and 10 µg/g of soil) and a control (uncontaminated with Pb or Cd) were used in a completely randomized static non-renewal bioassay design. We found that N. mbae more frequently preferred and burrowed into the control soil than the test soils. Avoidance was more at 500 µg/g Pb (ratio: 1:8) and 10 µg/g Cd (ratio: 1:2). The times to start and to complete burrowing, and the interval between both events were significantly extended in test soils, especially at 500 µg/g Pb and 10 µg/g Cd. Heavy metals contamination elicited increased activity of CAT, SOD and GPx, on short-term (day 2, d-2), and increased synthesis of GSH and MDA on short- and long-term (day 30, d-30) in concentration- and duration-dependent manners. The activity of CAT, SOD and GPx declined significantly on d-30. The heavy metals contamination resulted in both a significant loss in body weight, and mortality. Our preliminary results suggest that N. mbae is a suitable model organism for ecotoxicity studies, because it was able to detect and avoid Pb and Cd contaminated soils, delayed burrowing probably in search of suitable soil patches, and even escaped from heavily contaminated soil.

description: Higher dimensional non-renormalizable operators may modify the Standard Model Higgs potential in many interesting ways. Here, we consider the appearance of a second vacuum which may play an important role in cosmology. For the certain range of parameters, the usual second order electroweak phase transition is followed by a first order phase transition that may drive the late time accelerated expansion of the universe. Such a potential contains kink-like solutions which in turn can play a crucial role in reconstructing the global shape of the potential in colliders, as we explicitly demonstrate.

description: Online behavioral advertising, and the associated tracking paraphernalia, poses a real privacy threat. Unfortunately, existing privacy-enhancing tools are not always effective against online advertising and tracking. We propose Harpo, a principled learning-based approach to subvert online behavioral advertising through obfuscation. Harpo uses reinforcement learning to adaptively interleave real page visits with fake pages to distort a tracker's view of a user's browsing profile. We evaluate Harpo against real-world user profiling and ad targeting models used for online behavioral advertising. The results show that Harpo improves privacy by triggering more than 40% incorrect interest segments and 6x higher bid values. Harpo outperforms existing obfuscation tools by as much as 16x for the same overhead. Harpo is also able to achieve better stealthiness to adversarial detection than existing obfuscation tools. Harpo meaningfully advances the state-of-the-art in leveraging obfuscation to subvert online behavioral advertising

Preemption-Safe Spinlocks: Leveraging Hardware Transactional Memory to Improve Lock Tail Latency
Creators: name: Langas, Anthony J
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: In the development of concurrent applications, locks are a commonly used mechanism for safely synchronizing accesses to shared data objects. However, they are susceptible to the lock holder preemption (LHP) and priority inversion problems when used in conjunction with certain scheduling techniques such as time slicing. In response, past research has proposed methods which generally fall into 2 categories. (1) Proposing to widen the kernel-process interface to facilitate informed scheduling decisions. (2) Lock-free algorithms, which provide synchronization without mutual exclusion. In this paper, we propose a new solution to this problem, the Preemption-Safe Spinlock (PSSL). PSSL is a spinlock that allows a thread waiting on the lock to make progress upon detection of a lock holder preemption event. PSSL uses hardware transactional memory (HTM) to ensure correctness amid a false detection. We evaluate PSSL through experiments using variants of a buffer-fill application with critical section lengths up to approximately 880,000 cycles long and up to 64 threads running on separate cores. Some of these experiments involve pinning a CPU-intensive thread to the same core as one of the worker threads to observe how the synchronization method responds to scheduler-induced LHP. PSSL's performance in these experiments is compared to that of spinlock, mutex, and Intel's HTM paired with different configurations of exponential backoff. We find that PSSL performs similarly to spinlock in experiments where LHP is negligible. In addition, PSSL offers up to a 15% speedup and a 30x reduction in tail latencies over spinlock when the probability of scheduler-induced LHP is high with 2 worker threads and 1 CPU-intensive thread.

description: We explore the possibility to break time reversal invariance at the junction of quantum wires. The universal features in the bulk of the wires are described by the anyon Luttinger liquid. A simple necessary and sufficient condition for the breaking of time reversal invariance is formulated in terms of the scattering matrix at the junction. The phase diagram of a junction with generic number of wires is investigated in this framework. We give an explicit classification of those critical points which can be reached by bosonization and study the interplay between their stability and symmetry content.

description: For an elliptic curve $E$ defined over $\Q$ and for a rational prime $p$ of good reduction, one can define an integer $a_p$ related to the number of $\F_p$-points lying on the reduction of $E$ modulo $p$ as $a_p = p + 1 - \#E(\F_p)$. The integer $a_p$, called the Frobenius trace of $E$ modulo $p$, lies in the interval $(- 2 \sqrt{p}, 2 \sqrt{p})$ and has several other remarkable properties. In this thesis, we study the arithmetic properties of $a_p$, specifically how often $a_p$ is prime. Using heuristical reasoning similar to that used in formulating the Hardy-Littlewood Conjecture regarding the number of twin primes up to a bound $x$, it is natural to formulate a conjecture for the asymptotic growth of the number of primes $p \leq x$ for which $a_p$ is also prime. As evidence in support of this conjecture, we prove two main results, each in the case when $E$ is without complex multiplication and under the $\theta$-quasi Generalized Riemann Hypothesis. First, we establish an upper bound for the number of primes $p \leq x$ for which $a_p$ is prime; this bound has the correct order of magnitude, as predicted by the aforementioned conjecture. Then we prove a lower bound, also with the correct order of magnitude, for the number of primes $p \leq x$ such that $a_p$ is ``almost" prime, in the sense of having at most a certain fixed number of prime factors, distinct or indistinct.

description: This paper analyses the set of scientific publications in open access, other than journals (monographs, conferences proceedings, teaching materials and grey literature), published by Spanish public universities, studying their volume, documentary typology, level of description and open access policies with the aim of measuring their degree of incorporation and compliance with the principles of Open Science. An exhaustive review of the disposed material in open access by these publishers has been carried out, which has allowed to make a diagnosis of their level of open access publishing. Grey literature is the most common documentary type followed by the monograph, in the open publication of these publishers that does not reach even 5% of the average editorial production. The results allow us to conclude that the academic publishing, and more specifically the academic books in open access, still has a very reduced presence within the editorial production of these institutions.

description: We implemented sink particles in the adaptive mesh refinement (AMR) hydrodynamics code FLASH. Sink particles are created in regions of local gravitational collapse, and their trajectories and accretion can be followed over many dynamical times. We perform a series of tests including the time integration of circular and elliptical orbits, the collapse of a Bonnor-Ebert sphere and a rotating, fragmenting cloud core. We compare the collapse of a highly unstable singular isothermal sphere to the theory by Shu (1977), and show that the sink particle accretion rate is in excellent agreement with the theoretical prediction. To model eccentric orbits and close encounters of sink particles accurately, we show that a very small timestep is often required, for which we implemented subcycling of the N-body system. We emphasize that a sole density threshold for sink particle creation is insufficient in supersonic flows, if the density threshold is below the opacity limit. In that case, the density can exceed the threshold in strong shocks that do not necessarily lead to local collapse. Additional checks for bound state, gravitational potential minimum, Jeans instability and converging flows are absolutely necessary for a meaningful creation of sink particles. We apply our new sink particle module for FLASH to the formation of a stellar cluster, and compare to a smoothed particle hydrodynamics (SPH) code with sink particles. Our comparison shows encouraging agreement of gas properties, indicated by column density distributions and radial profiles, and of sink particle formation times and positions. We find excellent agreement in the number of sink particles formed, and in their accretion and mass distributions.

title: The development of financial reporting in Jordan: a survey of preparers' and users' attitudes and reporting practices
Creators: name: Abu-Nassar, Mohammad
Publisher: name: University of Kent
Year: 2021

description: When compared, the research on corporate financial reporting in developing countries has not been as in depth or widespread, as developed countries. This study attempts to fill this gap by examining the usefulness of corporate annual reports to users' needs in the Jordanian context. The study is based mainly on empirical evidence collected through questionnaire surveys of both users and preparers of corporate annual reports as well as annual reports of Jordanian quoted companies between the period 1981 to 1990. The study questioned five major groups of users: individual shareholders, institutional shareholders, bankers, academics and stockbrockers. Preparers of corporate annual reports were represented in the study by financial directors of companies listed on the Amman Financial Market. The evidence revealed that the adequacy of disclosure in Jordanian corporate annual reports had shown a remarkable improvement during the period between 1981 and 1990. However, such disclosure was still far from providing users with a sufficient amount of information, with companies publishing currently only about one third of what users may need. In the analysis, the findings indicated that companies tended to improve their level of disclosure when they had good news, high dividends and a high rate of return to report to outsiders. In addition, inadequacy of disclosure was found in corporate and annual reports of a) small companies, b) less profitable companies, c) companies operating in sectors other than the insurance sector, d) companies with a low level of dividends and e) companies with a high percentage of individual shareholders ownerships. The major factor discouraging companies to provide more disclosure voluntarily was considered by preparers to be the cost of collecting and publishing the necessary information. In contrast, the main advantage of voluntary disclosure was considered to be the improvement of company image and reputation. It was also found that companies in Jordan prepared their annual reports mainly for internal management purposes and they showed very little concern about the needs of several external groups of users such as the press, government and employees. The study concludes that there is a strong need for improvement in the adequacy of disclosure, comparability and reliability of information published in corporate annual reports and such improvements may need more legal regulation covering financial reporting in Jordan.
The preparation of a telescope for operation at millimeter wavelengths, and observations of carbon monoxide and in the galactic dust cloud lynds 134
Creators: name: Mahoney, Michael Joseph
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation is written in two parts. The first part discusses the development of a millimeter wave telescope at the University of British Columbia, and presents details on a very versatile yet cost effective computer control system which has been developed for this facility. Also included is a comprehensive theoretical and practical treatment of the problem of aligning an equatorially mounted telescope. The second part, on the other hand, presents the results of observations of the J = 1 - 0 transitions of ¹²C¹⁶O, ¹³C¹⁶O and ¹²C¹⁸O in the dark dust cloud Lynds 134. Analysis indicates that L134 is in fact comprised of four molecular clouds with nominal radial velocities of 0.1, 0.7, 2.7,and 4.0 km s⁻¹ with respect to the local standard of rest, and it is suggested that these clouds might be the result of fragmentation. The clouds at 0.7 and 2.7 km s⁻¹ are approximately isothermal (with an excitation temperature of ~12 K) and are shown to coincide with known HI absorption features, while the clouds at 2.7 and 4.0 km s⁻¹ coincide with regions of maximum visible extinction, and are also the most massive of the four clouds. Ac comparison of velocities and line widths for nine molecular species at the position of the 2.7 km s⁻¹ cloud suggests strongly that the atomic hydrogen coexists with the molecules, and does not form a shell as previously thought. It is estimated that in this cloud the H/H₂ abundance ratio is ≥7.7 x 10⁻³ and that the number density of atomic hydrogen is ~11 cm⁻³. In the region of maximum visible extinction on this cloud, the ¹³C¹⁶O/¹²C¹⁸O abundance ratio is 6.5 ± 0.9, but it appears to be significantly larger where the visible extinction is less, perhaps due to excitation effects. Finally, an analysis of the spatial dependence of the line widths indicates a collapse or expansion with a radial velocity dependence v ∝ r[sup -1/2] ; on the basis of some higher resolution CO results, and previous OH results, it is suggested, that it may be possible to distinguish between collapse or expansion, although better sensitivity is needed.

description: The article is focused on studying how to predict the failure times of coherent systems from the early failure times of their components. Both the cases of independent and dependent components are considered by assuming that they are identically distributed (homogeneous components). The heterogeneous components' case can be addressed similarly but more complexly. The present study is for non-repairable systems, but the information obtained could be used to decide if a maintenance action should be carried out at time t. Different cases are considered regarding the information available at time t. We use quantile regression techniques to predict the system failure times and to provide prediction intervals. The theoretical results are applied to specific system structures in some illustrative examples.
CEO Narcissism and Corporate Decision
Creators: name: Boamah, Evans Ofosu
Publisher: name: Lancaster University
Year: 2023

description: This thesis contains three essays investigating the effects of CEO
 narcissism on corporate decisions. In the first essay, I study whether CEO
 narcissism affects a firm’s share repurchase announcements and their
 implementations. I find that US firms with narcissist CEOs are more likely
 to make repurchase announcements and announce higher repurchase dollar
 amounts. However, these firms are less likely to follow through. Actual
 repurchases by these firms are less frequent and they use a smaller amount
 of cash for share buyback because they have a higher cashflow sensitivity
 of cash. Narcissist CEOs’ repurchase announcements are less driven by
 market timing and have a lower announcement effect compared to those by
 other CEOs. Finally, The higher rate and amount of repurchase
 announcements are more pronounced in poorly governed firms with
 narcissistic CEOs.

 In the second essay, I examine the relationship between CEO narcissism and
 the management of firm employees’ defined benefit (DB) pension plans in a
 sample of US firms. I find that firms with narcissist CEOs adjust their DB
 plan deficits at a slower rate than other firms. Further, narcissist CEOs
 display a slower speed of adjustment of the funding deficit towards the
 fully funded level if they have cash flow as a metric for their
 compensation. However, I find narcissist-managed firms to increase their
 adjustment speed more than other CEOs when they can enjoy more tax
 benefits through the tax deductions that come with pension contributions.
 I find that delay in DB pension adjustment by narcissist CEOs is more
 pronounced in poorly governed firms. Taken together, the results suggest
 that firms run by narcissist CEOs have a tendency to borrow more from
 employees to fund business operations and personal compensation than other
 firms.

 In the third essay, I examine the effect of CEO narcissism on corporate
 lobbying activities. I find keen involvement of narcissist-managed firms
 in corporate lobbying activities compared to other firms. Narcissist CEO
 lobbying activities increase corporate gains and firm value. Also,
 narcissist CEOs promote lobbying issues that serve the interest of
 shareholders. Further findings indicate that political strategies like
 lobbying by narcissistic CEOs significantly impact the allocation of
 government contracts. Finally, I find a significant positive relationship
 between CEO narcissism and environmental-related lobbying.

 My results suggest that narcissistic CEOs use environmental lobbying as a
 channel to generate narcissism supply.
