description: We apply a Bayesian "razor" to forecast Bayes factors between different parameterizations of the galaxy cluster mass function. To demonstrate this approach, we calculate the minimum size N-body simulation needed for strong evidence favoring a two-parameter mass function over one-parameter mass functions and visa versa, as a function of the minimum cluster mass.

Objective: To investigate the prevalence of decisional regret regarding preoperative fertility preservation choices after gender-affirming surgery or removal of reproductive organs. Design: Cross-sectional. Setting: University-based pratice. Patients: A total of 57 survey respondents identifying as transgender men or gender nonbinary with a history of gender-affirming surgery or removal of reproductive organs between 2014 and 2023 with the University of North Carolina Minimally Invasive Gynecology division. Intervention: Survey or questionnaire. Main Outcome Measures: The prevalence and severity of decisional regret regarding preoperative fertility preservation choices were measured with the use of the validated decisional regret scale (DRS) (scored 0-100). Secondary outcomes included patient-reported barriers to pursuing reproductive endocrinology and infertility consultation and fertility preservation treatment. Results: The survey response rate was 50.9% (57/112). "Mild" to "severe" decisional regret was reported by 38.6% (n = 22) of survey respondents, with DRS scores among all respondents ranging from 0-85. Higher median DRS scores were associated with patient-reported inadequacy of preoperative fertility counseling regarding implications of surgery on future fertility or family-building (0 vs. 50) and fertility preservation options (0 vs. 12.5). No desire for future fertility at the time of fertility counseling was the most frequent reason (68.4%) for declining a referral to reproductive endocrinology and infertility for additional fertility preservation discussion. Conclusions: Decisional regret regarding preoperative fertility preservation choices is experienced among transgender men or gender nonbinary persons after gender-affirming surgery or the removal of reproductive organs. Preoperative, patient-centered fertility counseling and fertility preservation treatments should be provided to reduce the risk of future regret.

description: We present a study of the outflowing ionized gas in the resolved narrow-line region (NLR) of the Seyfert 2 galaxy Mrk 573, and its interaction with an in- ner dust/gas disk, based on Hubble Space Telescope (HST) WFPC2 and STIS observations. From the spectroscopic and imaging information, we determined the fundamental geometry of the outflow and inner disk, via two modeling pro- grams used to recreate the morphology of these regions imaged with HST. We also determined that the bicone of ionizing radiation from the Active Galactic Nucleus (AGN) intersects with the inner disk, illuminating a section of the disk including inner segments of spiral arms, fully seen through structure mapping, which appear to be outflowing and expanding. In addition, we see high velocities at projected distances of \geq 2'' (- 700 pc) from the nucleus, which could be due to rotation or to in situ acceleration of gas off the spiral arms. We find that the true half opening angle of the ionizing bicone (53 degrees) is much larger than the apparent half-opening angle (34 degrees) due to the above geometry, which may apply to a number of other Seyferts as well.

Essays on supply chain management : risk management and productivity spillovers
Creators: name: Serpa, Juan Camilo
Publisher: name: University of British Columbia
Year: 2015

description: This thesis comprises three independent essays on supply chain management. In the first essay we collect data on 27,000 vertical relationships to study the importance of different channels of productivity spillovers between upstream and downstream firms. We explore the relative influence of two types of channels: endogenous and exogenous. The endogenous channel measures how a firm's productivity is affected by knowledge transfers (arising from collaboration and peer-mentoring). The exogenous channels measure the extent to which productivity is influenced by the partners' characteristics (e.g. geographic location, inventory turnover, financial leverage, etc.). We find that the endogenous channel is the primary source of spillovers. We also find that a firm's productivity is influenced more by the operational, than by the financial characteristics of its partners. The second essay unveils a previously unexplored role of business insurance in managing supply chain risk. We show that firms may strategically buy insurance purely as a commitment mechanism to prevent excessive free-riding by other firms. Specifically, we show that contractual incentives alone leave wealth-constrained firms with low incentives to prevent operational accidents, and firms with sufficient wealth with excessive incentives. Insurance allows the latter firms to credibly commit to lower effort, thereby mitigating the incentives of the wealth-constrained firms to free-ride. The third essay explores the interplay between public policy and risk management, when governments must strike a balance between safety and industry welfare. We focus on industries where operational accidents can be destructive and, as a result, where the cost of third-party liability is significant. Firms in these industries may be discouraged from entering the market as a result of these costs. If entry is inefficiently low, a social planner can incentivize firms through ex ante subsidies, which defray the costs associated with making operations safer, or ex post subsidies, which mitigate the financial damages caused by the accident. We demonstrate that when the social planner values reliability over market competition, it is optimal to offer ex ante subsidies alone. Conversely, when competition outweighs the benefits of reliability, a combination of ex ante and ex post subsidies is optimal.

description: To date, there is ample evidence to support the strong relationship between stress and insulin resistance. While diabetes mellitus acts as a potent stress inducer, stress may be an upstream event for insulin resistance as well. It is widely recognized that diabetes mellitus is more prevalent among people who have a stressful lifestyle; however, the underlying mechanisms are not well understood. In the current study, we surveyed the scientific literature for possible interactions between stress and insulin resistance and found that stress can impair glucose homeostasis, working through at least six molecular pathways.

description: We explicitly compute the 2-group of self-equivalences and (homotopy classes of) chain homotopies between them for any {\it split} chain complex $A_{\bullet}$ in an arbitrary $\kb$-linear abelian category ($\kb$ any commutative ring with unit). In particular, it is shown that it is a {\it split} 2-group whose equivalence class depends only on the homology of $A_{\bullet}$, and that it is equivalent to the trivial 2-group when $A_\bullet$ is a split exact sequence. This provides a description of the {\it general linear 2-group} of a Baez and Crans 2-vector space over an arbitrary field $\mathbb{F}$ and of its generalization to chain complexes of vector spaces of arbitrary length.

Essays on the capital market consequences of disclosures
Creators: name: Yang, Shuo
Publisher: name: University of British Columbia
Year: 2015

description: This thesis examines the capital market consequences of two new forms of disclosure: foreign cash holdings in 10-K filings, a semi-voluntary disclosure, and firms’ presentations at conferences hosted by a variety of third-party organizations, a voluntary disclosure. The first essay exploits the recent trend of disclosing foreign cash holdings by US multinational firms in 10-K filings and investigates the valuation of foreign cash holdings, both relative to domestic cash holdings and cross-sectionally. Firms whose filings in prior years receive a comment on foreign cash from the SEC are much more likely to disclose foreign cash, but internal and external governance structures also affect the likelihood of disclosure. I find that the valuation of foreign cash is similar to the valuation of domestic cash for the same firm. Cross-sectionally, I find that firms who need to pay higher repatriation tax to access foreign cash do not have less valuable foreign cash. Firms whose foreign operations have more severe agency problems have less valuable foreign cash, but firms with higher foreign growth opportunities have more valuable foreign cash. The second essay studies how managers’ presentations at different types of conferences affect firms’ information environments, including analyst forecast properties, stock price informativeness and liquidity. Despite their popularity, little is known about conference presentations’ impact on capital market efficiency, other than some studies implying that these disclosures might give conference participants an informational edge. I classify conferences based on sponsors into three categories: conferences hosted by brokerage houses (broker-hosted conferences), trade organizations (trade shows), and other parties (investor relation, or IR conferences), and calculate the frequency of attending these conferences for each firm. I find that information quality and uncertainty of the presentations differ across conferences. Broker-hosted conferences have a positive effect on all the information environment measures, IR conferences have a milder or no effect, whereas trade shows actually have a negative effect across the board. Among all the conferences, only presentations at trade shows are followed by stock price reversals, indicating an initial overreaction to such presentations, possibly due to managers’ incentive to oversell new products.

description: We present a quantum hyperdense coding protocol with hyperentanglement in polarization and spatial-mode degrees of freedom of photons first and then give the details for a quantum secure direct communication (QSDC) protocol based on this quantum hyperdense coding protocol. This QSDC protocol has the advantage of having a higher capacity than the quantum communication protocols with a qubit system. Compared with the QSDC protocol based on superdense coding with $d$-dimensional systems, this QSDC protocol is more feasible as the preparation of a high-dimension quantum system is more difficult than that of a two-level quantum system at present.

description:
Objectives: Health-related chatbots have demonstrated early promise for improving self-management behaviors but have seldomly been utilized for hypertension. This research focused on the design, development, and usability evaluation of a chatbot for hypertension self-management, called "Medicagent." Materials and Methods: A user-centered design process was used to iteratively design and develop a text-based chatbot using Google Cloud's Dialogflow natural language understanding platform. Then, usability testing sessions were conducted among patients with hypertension. Each session was comprised of: (1) background questionnaires, (2) 10 representative tasks within Medicagent, (3) System Usability Scale (SUS) questionnaire, and (4) a brief semi-structured interview. Sessions were video and audio recorded using Zoom. Qualitative and quantitative analyses were used to assess effectiveness, efficiency, and satisfaction of the chatbot. Results: Participants (n = 10) completed nearly all tasks (98%, 98/100) and spent an average of 18 min (SD = 10 min) interacting with Medicagent. Only 11 (8.6%) utterances were not successfully mapped to an intent. Medicagent achieved a mean SUS score of 78.8/100, which demonstrated acceptable usability. Several participants had difficulties navigating the conversational interface without menu and back buttons, felt additional information would be useful for redirection when utterances were not recognized, and desired a health professional persona within the chatbot. Discussion: The text-based chatbot was viewed favorably for assisting with blood pressure and medication-related tasks and had good usability. Conclusion: Flexibility of interaction styles, handling unrecognized utterances gracefully, and having a credible persona were highlighted as design components that may further enrich the user experience of chatbots for hypertension self-management.

description: A scanning force microscope tip is used to write ferroelectric domains in He-implanted single-crystal lithium niobate and subsequently probe them by piezoresponse force microscopy. Investigation of cross-sections of the samples showed that the buried implanted layer, $\sim 1$\,\textmu m below the surface, is non-ferroelectric and can thus act as a barrier to domain growth. This barrier enabled stable surface domains of $< 1$\,\textmu m size to be written in 500\,\textmu m-thick crystal substrates with voltage pulses of only 10\,V applied to the tip.

description: We analyze the attosecond electron dynamics in hydrogen molecular ion driven by an external intense laser field using ab-initio numerical simulations of the corresponding time-dependent Schr{ö}dinger equation and Bohmian trajectories. To this end, we employ a one-dimensional model of the molecular ion in which the motion of the protons is frozen. The results of the Bohmian trajectory calculations do agree well with those of the ab-initio simulations and clearly visualize the electron transfer between the two protons in the field. In particular, the Bohmian trajectory calculations confirm the recently predicted attosecond transient localization of the electron at one of the protons and the related multiple bunches of the ionization current within a half cycle of the laser field. Further analysis based on the quantum trajectories shows that the electron dynamics in the molecular ion can be understood via the phase difference accumulated between the Coulomb wells at the two protons. Modeling of the dynamics using a simple two-state system leads us to an explanation for the sometimes counter-intuitive dynamics of an electron opposing the classical force of the electric field on the electron.

description: The images of relativistic jets from extragalactic sources produced by gravitational lensing by galaxies with different mass surface density distributions are modeled. In particular, the following models of the gravitational lens mass distribution are considered: a singular isothermal ellipsoid, an isothermal ellipsoid with a core, two- and three-component models with a galactic disk, halo, and bulge. The modeled images are compared both between themselves and with available observations. Different sets of parameters are shown to exist for the gravitationally lensed system B0218+357 in multicomponent models. These sets allow the observed geometry of the system and the intensity ratio of the compact core images to be obtained, but they lead to a significant variety in the Hubble constant determined from the modeling results.

description: We study the magnetism of a frustrated four-leg spin-1/2 ladder with transverse periodic boundary conditions: the frustrated four-spin tube (FFST). Using a combination of series expansion (SE), based on the continuous unitary transformation method and density-matrix renormalization group (DMRG) we analyze the ground-state, the one-, and the two-particle excitations in the regime of strong rung-coupling. We find several marked differences of the FFST with respect to standard two-leg ladders. First we show that frustration destabilizes the spin-gap phase of the FFST which is adiabatically connected to the limit of decoupled rung singlets, leading to a first order quantum phase transition at finite inter-rung coupling. Second, we show that apart from the well-know triplon branch of spin-ladders, the FFST sustains additional elementary excitations, including a singlon, and additional triplons. Finally we find, that in the two-particle sector the FFST exhibits collective (anti)bound states similar to two-leg ladders, however with a different ordering of the spin-quantum numbers. We show that frustration has significant impact on the FFST leading to a flattening of the ground-state energy landscape, a mass-enhancement of the excitations, and to a relative enhancement of the (anti)binding strength. Where possible we use DMRG to benchmark the findings from our SE calculations, showing excellent agreement.

description: The Alpha Magnetic Spectrometer (AMS) is a particle physics detector designed for a high precision measurement of cosmic rays in space. AMS phase-2 (AMS-02) is scheduled to be installed on the ISS for at least three years from September 2010. The AMS-01 precursor experiment operated successfully during a 10-day NASA shuttle flight in June 1998. The orbital inclination was 51.7° at a geodetic altitude between 320 to 380 km. Nearly 200,000 Z>2 nuclei were observed by AMS-01 in the rigidity range 1-40 GV. Using these data, it is possible to investigate the relative abundances and the energy spectra of the primary cosmic rays, providing relations with their sources and propagation processes. Preliminary results on the B/C ratio in 0.4-19 GeV/nucleon kinetic energy are presented.

description:
George Floyd's murder caused many firms to reveal how exposed they are to racial diversity issues. We examine investor and firm behaviors after this socially significant event to provide evidence on the valuation effects of the exposure and ensuing corporate responses. We develop a text‐based measure of a firm's exposure to racial diversity issues from conference call transcripts and find that, after the murder of George Floyd, firms with diversity exposure experience a stock price decrease of approximately 0.7% around the date of the conference call. We provide evidence that this effect is attributable to race‐related exposure and not gender‐related exposure. Initiatives taken by firms mitigate the negative market reaction. We document that firms with racial diversity exposure respond by appointing Black directors. The stock market views appointments of Black directors more favorably after George Floyd's murder, except when they are perceived as symbolic. We also find that firms with greater exposure to racial diversity are more likely to establish diversity, equity, and inclusion (DEI) departments, appoint DEI leaders, specify diversity goals, increase supply chain diversity, and donate to racial justice causes. Our paper provides evidence that exposure to racial diversity issues adversely affects firm value, and companies address the exposure by taking actions.

description: We present a study of the Silicon-bearing species detected in a line confusion limited survey towards Orion KL performed with the IRAM 30-m telescope, which ranges from 80 to 280 GHz. Our aim is to derive physical and chemical conditions for each family taking into account all observed lines from all isotopologues of each species. We have modeled the lines of the detected molecules using a radiative transfer code, which permit us to choose between LVG and LTE approximations depending on the physical conditions of the gas. We have used appropriate collisional rates for the LVG calculations. For the v=1 state of SiO we have detected the J=2-1 line and, for the first time in this source, emission in the J=4-3 transition, both of them showing strong masering effect. For SiO v=0, we have detected 28SiO, 29SiO, and 30SiO; in addition, we have mapped the J = 5-4 SiO line. For SiS, we have detected the main species, 29SiS, and SiS v=1. Unlikely other species detected in Orion KL (IRc2), the emission peak of SiS appears at a velocity of ~15.5 km s-1; a study of the 5-4 SiO line around IRc2 shows this feature as an extended component that probably arises from the interaction of the outflow with the ambient cloud. We derive a SiO/SiS column density ratio of ~13 in the plateau component. Besides, we provide upper limits to the column density of several non-detected Silicon-bearing species. The results of our chemical models show that while it is possible to reproduce SiO in the gas phase (as well as on the grains), SiS is a product of surface reactions, most likely involving direct reactions of S with Si.

The longitudinal spin transfer is found to be D_LL= -0.03\pm 0.13 (stat) \pm 0.04(syst)$ for inclusive $Λ$ and $D_{LL} = -0.12 \pm 0.08(stat) \pm 0.03(syst)$ for inclusive $\barΛ$ hyperons with $ = 0.5$ and $ = 3.7 GeV/c$. The prospects with 2009 data and the future measurements are also given.

Political (Meta-)Dehumanization in Mental Representations: Divergent Emphases in the Minds of Liberals Versus Conservatives.

Year: 2023

description:
We conducted two reverse-correlation studies, as well as two pilot studies reported in the online supplement (total N = 1,411), on the topics of (a) whether liberals and conservatives differ in the types of dehumanization that they cognitively emphasize when mentally representing one another, and if so, (b) whether liberals and conservatives are sensitive to how they are represented in the minds of political outgroup members. Results suggest that partisans indeed differ in the types of dehumanization that they cognitively emphasize when mentally representing one another: whereas conservatives' dehumanization of liberals emphasizes immaturity (vs. savagery), liberals' dehumanization of conservatives more strongly emphasizes savagery (vs. immaturity). In addition, results suggest that partisans may be sensitive to how they are represented. That is, partisans' meta-representations-their representations of how the outgroup represents the ingroup-appear to accurately index the relative emphases of these two dimensions in the minds of political outgroup members.

victim rights

description: Following a long process of development in this field, both based on empirical research and European as well as national legislation, victims of crime are nowadays no longer reduced to their role as witnesses but are seen as an important party in criminal proceedings, thereby acknowledging both their specific role and the strains they are exposed to. In order to enable victims to participate actively, they need to be able to understand the proceedings. Consequently, for victims not capable of speaking the language of service, an interpreter has to be appointed. Through a transdisciplinary study in Austria, experiences of both interpreters and victim support organisations concerning specific challenges in this field were examined. The results indicated that although both groups assessed the legal and practical framework for interpreters as rather good, specific deficits could be identified. These concerned for example the insufficient number of high-quality interpreters, cultural barriers and different perceptions concerning issues such as domestic abuse or sexual offences as well as situations in which interpreters and victims both come from the same ethnical community, leading to a lack of trust from the victims concerning the confidentiality of the interpreters.

description: We have used the greatly enhanced spectral capabilities of the Expanded Very Large Array to observe both the 22.3 GHz continuum emission and the H66α recombination line toward the well-studied Galactic emission-line star MWC 349A. The continuum flux density is found to be 411 $\pm$ 41 mJy in good agreement with previous determinations. The H66α line peak intensity is about 25 mJy, and the average line-to-continuum flux ratio is about 5%, as expected for local thermodynamic equilibrium conditions. This shows that the H66α recombination line is not strongly masing as had previously been suggested, although a moderate maser contribution could be present. The He66α recombination line is also detected in our observations; the relative strengths of the two recombination lines yield an ionized helium to ionized hydrogen abundance ratio y+ = 0.12 $\pm$ 0.02. The ionized helium appears to share the kinematics of the thermally excited ionized hydrogen gas, so the two species are likely to be well mixed. The electron temperature of the ionized gas in MWC 349A deduced from our observations is 6,300 $\pm$ 600 K.

description: We present absolute parallaxes and proper motions for seven members of the Hyades open cluster, pre-selected to lie in the core of the cluster. Our data come from archival astrometric data from FGS 3, and newer data for 3 Hyads from FGS 1R, both white-light interferometers on the Hubble Space Telescope (HST). We obtain member parallaxes from six individual Fine Guidance Sensor (FGS) fields and use the field containing van Altena 622 and van Altena 627 (= HIP 21138) as an example. Proper motions, spectral classifications and VJHK photometry of the stars comprising the astrometric refer- ence frames provide spectrophotometric estimates of reference star absolute parallaxes. Introducing these into our model as observations with error, we determine absolute parallaxes for each Hyad. The parallax of vA 627 is significantly improved by including a perturbation orbit for this previously known spectroscopic binary, now an astrometric binary. Compared to our original (1997) determina- tions, a combination of new data, updated calibration, and improved analysis lowered the individual parallax errors by an average factor of 4.5. Comparing parallaxes of the four stars contained in the Hipparcos catalog, we obtain an average factor of 11 times improvement with the HST . With these new results, we also have better agreement with Hipparcos for the four stars in common. These new parallaxes provide an average distance for these seven members, < D > = 47.5 pc, for the core a \pm 1 - σ dispersion depth of 3.6 pc, and a minimum depth from individual components of 16.0 \pm 0.9 pc. Absolute magnitudes for each member are compared to established main sequences, with excellent agreement. We obtain a weighted average distance modulus for the core of the Hyades of m-M=3.376 \pm 0.01, a value close to the previous Hipparcos values, m-M=3.33\pm 0.02.

description: Discrete non-abelian flavor symmetries give in a natural way tri-bimaximal (TBM) mixing as showed in a prototype model. However neutrino mass matrix pattern may be very different from the tri-bimaximal one if small deviations of TBM will be observed. We give the result of a model independent analysis for TBM neutrino mass pattern.

description: In this review article, we present a unified approach to solving discrete, integrable, possibly non-commutative, dynamical systems, including the $Q$- and $T$-systems based on $A_r$. The initial data of the systems are seen as cluster variables in a suitable cluster algebra, and may evolve by local mutations. We show that the solutions are always expressed as Laurent polynomials of the initial data with non-negative integer coefficients. This is done by reformulating the mutations of initial data as local rearrangements of continued fractions generating some particular solutions, that preserve manifest positivity. We also show how these techniques apply as well to non-commutative settings.

description: Monoatomic chains of molybdenum encapsulated in single walled carbon nanotubes of different chiralities are investigated using density functional theory. We determine the optimal size of the carbon nanotube for encapsulating a single atomic wire, as well as the most stable atomic arrangement adopted by the wire. We also study the transport properties in the ballistic regime by computing the transmission coefficients and tracing them back to electronic conduction channels of the wire and the host. We predict that carbon nanotubes of appropriate radii encapsulating a Mo wire have metallic behavior, even if both the nanotube and the wire are insulators. Therefore, encapsulating Mo wires in CNT is a way to create conductive quasi one-dimensional hybrid nanostructures.

description: The main theme of this review is the many-body physics of vortices in quantum droplets of bosons or fermions, in the limit of small particle numbers. Systems of interest include cold atoms in traps as well as electrons confined in quantum dots. When set to rotate, these in principle very different quantum systems show remarkable analogies. The topics reviewed include the structure of the finite rotating many-body state, universality of vortex formation and localization of vortices in both bosonic and fermionic systems, and the emergence of particle-vortex composites in the quantum Hall regime. An overview of the computational many-body techniques sets focus on the configuration interaction and density-functional methods. Studies of quantum droplets with one or several particle components, where vortices as well as coreless vortices may occur, are reviewed, and theoretical as well as experimental challenges are discussed.

description: “Eyes are windows of the Soul” (Shakespeare, 1609, Sonnet 46). That which is seen in the eye, that is the Self (Sages, 1947, Chandogya Upanishad, p.124). Self or Soul is the source of Consciousness and is Consciousness itself. It is this Consciousness who experiences Awareness through the five senses by intention, attention, memory, attitude and behaviour. A case study, the practice of an individual, deeply analysed, understood for more than 35years, applied to prevent and overcome neuroses is explained here with an attempt to know how Consciousness plays different roles in a human being’s cognitive process and how it affects Neurotic symptoms. It is explained how Indian and Western Psychology understand consciousness and its application in real life. The Case study proves that when the role of Consciousness and its physical location is understood, it would benefit enhancing the cognition capability of an individual in concentration, problem solving, creativity and modifying behaviour reducing anxiety, stress, depression and protects from Non Communicable Life- style Diseases.
Perceptions of Bisexual Individuals Depend on Target Gender

description:
Across three experiments (total N = 1,149), we examine whether bisexual men (more so than women) are viewed as similar to their same-gender gay counterparts and whether bisexual women (more so than men) are viewed as similar to their same-gender heterosexual counterparts. We find support for the notion that bisexual men are stereotyped as more similar to their gay counterparts than bisexual women are. These perceptions of bisexual targets’ stereotypical similarity to their gay counterparts were linked to identity-denying perceptions that bisexual individuals are “actually gay,” a belief held more strongly about bisexual men (vs. women). Bisexual men and women were viewed as possessing stereotypically heterosexual characteristics to similar extents, although bisexual women (vs. men) were indeed more strongly characterized by the identity-denying belief that they are “actually heterosexual.” Collectively, these findings suggest that bisexual men and women encounter different challenges to their identities that may require different interventions.

description: From a survey for redshifted HI 21-cm and OH 18-cm absorption in the hosts of a sample of radio galaxies and quasars, we detect HI in three of the ten and OH in none of the fourteen sources for which useful data were obtained. As expected from our recent result, all of the 21-cm detections occur in sources with ultra-violet continuum luminosities of L < 10^23 W/Hz. At these "moderate" luminosities, we also obtain four non-detections, although, as confirmed by the equipartition of detections between the type-1 and type-2 objects, this near-50% detection rate cannot be attributed to unified schemes of active galactic nuclei (AGN). All of our detections are at redshifts of z < 0.67, which, in conjunction with our faint source selection, biases against UV luminous objects. The importance of ultra-violet luminosity (over AGN type) in the detection of 21-cm is further supported by the non-detections in the two high redshift z ~ 3.6 - 3.8 radio galaxies, which are both type-2 objects, while having L > 10^23 W/Hz. Our 21-cm detections in combination with those previously published, give a total of eight (associated and intervening) HI absorbing sources searched and undetected in OH. Using the detected 21-cm line strengths to normalise the limits, we find that only two of these eight may have been searched sufficiently deeply in OH, although even these are marginal.

From density functional theory to the functional renormalization group: superconductivity in the iron pnictide LiFeAs

description: A combined density functional theory and functional renormalization group method is introduced which takes into account orbital-dependent interaction parameters to derive the effective low-energy theory of weakly to intermediately correlated Fermi systems. As an application, the competing fluctuations in LiFeAs are investigated, which is the main representative of the 111 class of iron pnictides displaying no magnetic order, but superconductivity, for the parent compound. The superconducting order parameter is found to be of s+- type driven by collinear antiferromagnetic fluctuations. They eventually exceed the ferromagnetic fluctuations stemming from the small hole pocket at the Gamma point, as the system flows to low energies.

Essays in information privacy

Publisher: name: University of British Columbia

description: This thesis explores absence of proficient online privacy markets, where sellers can offer privacy enhanced services to consumers, who value privacy. Over three papers, I provide insight to aspects that hinder these markets and potential ways to remedy them. In the first paper, I contend that the changing nature of transactions in online markets – transactions that include consumers’ personal information – has introduced another aspect of uncertainty: privacy uncertainty. I theoretically explore the relationship among privacy uncertainty and seller and product uncertainty. Since uncertainty is the result of information asymmetry, I delve deeper into the nature of information asymmetry by distinguishing between its pre-purchase and post-purchase aspects and their respective effects on privacy uncertainty. Using lab experiments, I demonstrate that post-purchase information asymmetry leads to higher privacy uncertainty, a result that discredits the contemporary practice of using “notice and consent” in online markets. The second paper explores how sellers can improve the communication of their privacy practices and profit from them. To achieve this I define what good privacy practices mean and describe how to measure the quality of such practices. I theorize that app sellers can make better privacy claims if they also include data that supports their privacy claims and provide information about the practices of other similar app sellers (category-claims). I study these propositions across three experiments and find that category claims lead to greater perception of privacy quality as well as willingness to buy. While prior privacy literature has placed an emphasis on understanding consumer privacy preferences at the time of information disclosure, the last paper explores what happens after the information has been disclosed. In particular, I am interested in understanding consumers’ behavior after they experience a privacy failure, which occurs when consumer’s expectations about collection, use and protection of their personal information are disconfirmed. Using the critical incidence technique, we surveyed 321 individuals who had experienced a privacy failure and found that consumers predominantly react by exhibiting “helplessness”, which can be alleviated by providing a simple recovery mechanisms and privacy controls that enable consumers to add, remove and monitor their collected personal information.
