description: Competition between electronic and atomic reconstruction is a constantly recurring theme in transition-metal oxides. We use density functional theory calculations to study this competition for a model system consisting of a thin film of the polar, infinite-layer structure ACuO2 (A=Ca, Sr, Ba) grown on a nonpolar, perovskite SrTiO3 substrate. A transition from the bulk planar structure to a chain-type thin film accompanied by substantial changes to the electronic structure is predicted for a SrCuO2 film fewer than five unit cells thick. An analytical model explains why atomic reconstruction becomes more favorable than electronic reconstruction as the film becomes thinner, and suggests that similar considerations should be valid for other polar films.
Justice in networked publics: How platform affordances shaped the discourse around Making a Murderer
Creators: name: Carey, Alaxandra Amelia
Publisher: name: Arts
Year: 2018
Subjects: subject: Mass Communications

description: When the documentary series Making a Murderer was released on Netflix, people analyzed and discussed the details of the case through social media platforms. These platforms acted as networked publics where users were afforded the ability to discuss larger social issues like class and racial inequality, and the effectiveness and fairness of the criminal justice system. This thesis explores how networked publics are established by the affordances of specific social media platforms in relation to discussions about criminal justice that were performed as part of the reception of Making a Murderer. Specifically, I use critical technocultural discourse analysis to examine how Facebook, Twitter, Reddit and Tumblr acted as facilitators of networked public spaces for the circulation of specific discourses about criminal justice. I argue that studying multiple platforms is an appropriate approach to understand how the series’ reception constituted a networked public that opened up public discourse about criminal justice issues beyond the scope of the series
Scalar and Pseudoscalar Glueball Masses within a Gaussian Wavefunctional Approximation

description: The lowest scalar and pseudoscalar glueball masses are evaluated by means of the time-dependent variational approach to the Yang-Mills gauge theory without fermions in the Hamiltonian formalism within a Gaussian wavefunctional approximation. The glueball mass is calculated as a pole of the propagator for a composite glueball field which consists of two massless gluons. The glueball propagator is here evaluated by using the linear response theory for the composite external glueball field. As a result, a finite glueball mass is obtained through the interaction between two massless gluons, in which the glueball mass depends on the QCD coupling constant g in the nonperturbative form.

description: I followed Matthew Ally’s bold invitation and in my mind, I joined him and the Apollo 8 astronauts as they were witnessing the 'Earthrise' for the first time. He was right – the mere imagination of this image brings up a feeling that we may all too often forget when we try to formulate the ethical foundations, the precise definition or the scientific basis of the pursuit of sustainability. That feeling was, perhaps, as Dr. Ally put it, an experience of sustainability, and historically, as he describes, it was a catalyst of our ethical reasoning that sustainability is a value and the scientific understanding that sustainability is a fact. We may not realize how much we need these experiences. Of course, we do not need to travel to space to have them, to realize with wonder that there is nothing inevitable or ordinary or obvious about the stability of the earth system, the living planet, Gaia - whatever you wish to call it. This prolonged and relatively stable period in its history has probably made possible the development of human civilization, and some version of the anthropic principle would suggest that it must be that way, because otherwise there would be no one to notice it. But that isn’t really the point. All around us, nature is full of the complex self-regulating interactions and feedbacks that help the earth system sustain herself, that show us that sustainability is a possible, yet difficult and precious feat. In that sense, this sustainability is indeed nothing short of a remarkable, wonderful and under-appreciated fact. And our society may well need to cultivate this experience if it is to do better at appreciating and protecting it.

description: Throughout the life cycle of a geoscience career gender inequalities still exist, even in the face of legislative change. One response in Alberta is the formation of professional women’s groups. Drawing on feminist geography, the objective of this research was to explore the social relations and power structures involved within the work environment that categorized where women’s groups are created, why they are created, and the strategies used in addressing gender disparities and inequality. This mixed methods study included an inventory of current groups that exist in Alberta, an online survey to reach professional STEM women within the geoscience community who have been members of one or more professional women’s groups, and in-depth semistructured interviews with three key actors from one Alberta based group. The intended outcomes are to create evidence-based solutions, which in turn will help contribute to concrete solutions to better support professional female geoscientists in Alberta.

description: Sources, seasonal pattern of elemental carbon(EC), organic carbon(OC), and total carbon from dry deposition and precipitation in Kananaskis and Calgary were assessed using thermo-optical methods. Vehicle exhaust was inferred to be dominant source of carbon throughout the year with an identical OC/EC of 22±14 in Calgary and 22±5 in Kananaskis in dry deposition. Biogenic OC signal was absent in Kananaskis in precipitation or dry deposition. Biomass burning, with a lower OC/EC both in winter and summer, was potentially associated with recreation and tourism in Kananaskis. Sources from long-range transport impact both locations simultaneously. A lower boundary layer at night concentrates TC and a higher boundary layer in the day lower the concentration in both locations. OC is much more easily removed by precipitation than EC due to is larger surface area and size and OC/EC ratios in precipitation reaching 130 were observed in Calgary while those in Kananaskis reached 46.
Downstream environmental impacts of reservoir high outflows - with a focus on fisheries
Creators: name: Naghibi, Ali
Publisher: name: University of British Columbia
Year: 2011

description: Extreme floods pose a significant risk to communities and environments in river systems throughout the world. In many cases, sensitivity of this issue is heightened for regulated rivers where downstream impacts of reservoirs are directly affected by operational decisions. Therefore, many North American jurisdictions require asset owners to assess downstream effects. Loss of life and economic impacts have been widely addressed in the literature. Nevertheless, immediate and long-term environmental impacts of such extreme events have not been holistically addressed. This work develops a framework for quantitatively estimating immediate and long-term fisheries impacts of extreme floods. The framework may also be generalized to other environmental systems. Several models are developed to support it. The immediate effects of extreme events are assessed with three models. These include: a probabilistic individual-based model that employs the results of a transient hydrodynamic model to estimate fish loss during extreme floods; a sampling simulation model that utilizes the results of a transient morphodynamic model and derives a probabilistic relationship between egg loss and flood intensity; and a habitat change estimation model that evaluates the available habitat difference before and after extreme events, given the results of hydrodynamic and morphodynamic models. A fish population recovery model is also developed and employed to estimate long-term impacts of extreme events, given the results of the immediate impact estimation models. An approach for estimating a number of risk-based performance measures that characterize the impacts and recovery from extreme events is also developed. These performance measures include existing formulations for vulnerability, engineering resilience, and ecological resilience, as well as a new measure which is introduced in this work, as vulnerability divided by engineering resilience. This new performance measure is designed to characterize both short- and long-term performance of the environmental system. Planning, design, and real-time operation of reservoirs, participatory water use planning, and licensing and relicensing decisions for proposed and existing water resource projects are cases in which such estimates may be useful. Applicability of this framework is demonstrated for the case study of the Lower Campbell River in British Columbia, Canada.

Near the density-driven Mott transition, the expression of the pressure P(μ,T) versus chemical potential and temperature is similar to that of a dilute Bose gas but with renormalized mass m^* and scattering length a^*. m^* is the mass of the elementary excitations at the quantum critical point governing the transition from the superfluid phase to the Mott insulating phase, while a^* is related to their effective interaction at low energy. We use a nonperturbative renormalization-group approach to compute these parameters as a function of the ratio t/U between hopping amplitude and on-site repulsion.

description: It is not enough just to 'love nature' or want to be 'in harmony with Gaia.' Our relation to the natural world takes place in a place, and it must be grounded in information and experience.—Gary Snyder Since it first came into prominence in the early 1980s, the concept of sustainability has found its way into virtually all discussions of the future of Earth and its inhabitants. Though its meaning seems straightforward enough—i.e., that we must behave today in such a way as to preserve the prospects for future generations to flourish (cf. World Commission on Environment and Development 1987)—the range of specific inflections is notoriously broad. The term is used by free-market neoconservatives, by liberal welfare statists, and by anarcho-socialists. It is used by atheists, agnostics, and believers. It is used by advocates of hands-off back-to-nature lifestyles, by advocates of hands-on earth stewardship, and by advocates of heavy-handed programs for geoengineering. Some even speak of a "sustainability revolution," an emergent global paradigm shift that will rival the industrial revolution in historical significance; and others of a global commitment to sustainability-oriented social and environmental activism now in the hands of the largest movement the world has ever seen. Revolution or not, sustainability is for everyone, it seems. They cannot possibly all mean the same thing by the term.

description: Real-time implementation of digital predistortion (DPD), a technique for linearizing power amplifiers, has gained importance recently due to stringent transceiver performance specifications for future wireless networks. Precise delay estimation and alignment is imperative for any DPD algorithm to work. Several algorithms are present in the literature on the topic. However, the difficulties arise from energy efficiency and the low-cost implementation of these algorithms. The goal of this work is to implement real-time delay alignment of high bandwidth signals for transmitter impairment compensation in systems using low sampling rate analog-to-digital converters (ADCs). The proposed system uses a resource efficient and scalable design which is based on correlation and fractional delay filters, which can be implemented in the hardware and seamlessly integrated with any DPD system. Both simulation and hardware results, on field programmable gate arrays (FPGAs), have shown improvement in DPD performance when the delay estimation system is employed.

description: During the American Civil War, the military forces of the United States required an inordinate number of volunteers to fill the ranks. Historians to date have emphasized the self-motivation of the men who enlisted for duty in the Union armed forces, and as a result, have overlooked how recruiters utilized communications media to entice their service. This thesis examines the use of propaganda to promote enlistment in the Union military during the American Civil War. Throughout the conflict, political figures, military leaders, printers and publishers, prominent citizens, members of voluntary societies dedicated to recruiting, and other self-declared patriots produced thousands of documents and oratories imploring men to join the armed forces. In doing so, these individuals engaged in intentional acts of propaganda. The styles and forms taken by their efforts, however, more clearly reflect the communications culture of the antebellum era than the iconic propaganda campaigns of twentieth-century conflicts. The multiplicity of arguments recruiters made in favour of volunteering indicates that to them, their intended outcome—filling the ranks—was more important than the reasons they provided for doing so.

description: Thirty-three compounds (1–33) were isolated from the rhizomes of Osmunda japonica. Their structures were elucidated on the basis of spectral analysis and identified as ent-kaurene terpenoids (1–3), anthraquinones (4–8), flavonoids (9–12), steroids (13–15), and other compounds (16–33). Compound 1–14, 19–27 were isolated from the genus osmunda for the first time. Compound 28–29 were isolated from the plant for the first time. Cytotoxicities of all compounds against Hela, HepG2 and A549 cell lines were measured by MTT assay, and their antioxidant activities were determined by DPPH and ABTS radical scavenging assays. Compound 2 exhibited potent cytotoxicity against Hela, HepG2 cell lines with IC50 values of 9.31 and 9.66 μM, respectively. Compound 9 showed good antioxidant activity. The Trolox-equivalent antioxidant capacity (TEAC) value was 0.95 mM in ABTS assay, and the IC50 value was 18.63 μM in DPPH assay.

description: The paper investigates a feature valuation in the context of more than one acces-

sible goal. Concretely, the paper provides novel empirical evidence that there is

no φ-feature resolution in syntactic agree. The apparent feature resolution of gen-

der and number agreement previously reported in the Slavic literature on agree-

ment with coordinated DPs is a side-effect of morphological realization of person

feature that arises at the syntax–semantics interface. Furthermore, the proposal

suggests that even non-default overt morphological marking of agreement might

not faithfully reflect the narrow-syntax feature valuation, a result which seriously

questions the validity of some core generalizations about agreement properties of

natural languages. The core data comes from the agreement with coordinated noun

phrases in Czech.

description: Rock Eval pyrolysis is a standard industry technique used to evaluate the hydrocarbon-generating potential of a formation by quantifying its total organic matter content and thermal maturity. By utilizing a new Rock Eval procedure (ESH Rock Eval), in which the heating rate is slowed down over an extended temperature range, different hydrocarbon components are more easily distinguished due to enhanced peak resolution. The impacts of these various hydrocarbon types on reservoir quality is evaluated by observing the evolution of organic matter and petrophysical properties during pyrolysis. With the elution of the free hydrocarbons in the sample (S1 peak in Rock Eval), petrophysical properties do not notably change. However, significant changes occur after the S2a and S2b peaks, which correspond to the pyrolysis of pervasive, fluid-like hydrocarbon residue (FHR) which coats mineral grains, and the remaining organic matter (solid bitumen) that resides in the larger pore spaces in the samples, respectively. This work was evaluated utilizing core and drill cuttings samples from the Montney, Duvernay and Doig Formations from the Western Canadian Sedimentary Basin.

description: Liberation theology has largely ceased to develop critiques of idolatry, especially in the United States. I will argue that the critique is still viable in Christian theology and promising for the future of liberation theology, by way of reformulating Ada María Isasi-Díaz’s framework of kin-dom within the triune economy. Ultimately this will mean reconsidering our understanding of and commitment to divinity and each other—in a word, faith. The idea to move liberation theology from theology to other disciplines drives discussion in liberation theology circles, especially in the US, as we talk about the future. Yet if we turn to, say, social and critical theory as primary lenses, can the future of liberation theology still allow for the charge of idolatry that it once maintained? To say yes to idolatry critique seems to require something that other disciplines cannot fully support or sometimes even consider: namely faith as humanity’s positive response to both transcendent and immanent divine work.
A measurement method for U-Th-Sm/He dating of apatite by laser ablation

description: Thermochronology is a useful tool for dating thermal evolution of rocks in the upper crust. Thermochronometers have the ability to record the cooling of a rock through varying temperature windows. The apatite U-Th/He system is one of the low-temperature thermochronological systems that records cooling temperatures from 45-80°C. Apatite U-Th/He dating is conventionally done through whole grain analysis, where grains are picked and measured and then packed into Nb capsules which are heated in a vacuum to extract and measure the 4He content. Grains are subsequently dissolved and their U, Th, and Sm concentrations are measured by solution ICP-MS. This study addresses a new method of U-Th/He dating using apatite by laser ablation. In the laser ablation method grains are mounted in a vacuum stable medium and then ablated using a laser in a vacuum cell. The laser ablation method has several advantages over whole-grain measurements that limit bias from the grain selection process and improve analytical efficiency. An independently characterised megacryst of Durango apatite is used as a calibration material for the new laser ablation method. The megacryst was characterised at the University of Calgary and the University of Colorado Boulder by conventional whole-grain dating. The analysis yields an age of 32.56 ± 0.34 Ma. The measured age compares well to published ages for Durango apatite. I present here a new method of laser ablation U-Th/He on apatite. The method generally follows previously published laser ablation methodologies for zircon, monazite and titanite with modifications suited for apatite. Grains were mounted using a heated platen press, which pressed samples into FEP bonded to an aluminum backing plate. Samples were loaded into an ultra high vacuum chamber and ablated using a excimer laser and the liberated 4He is measured using an quadrupole mass spectrometer system. The ablated sites were imaged using an optical profilometer and ablated pit volume measured using PitVol, a custom MatLabTM algorithm. After the pit volume measurement, U, Th and Sm concentrations were measured by laser ablation ICP-MS and the U-Th-Sm/He date calculated. The method presented was validated using the characterized Durango apatite megacryst and Fish Canyon Tuff (FCT) apatite reference materials. Weighted average of Durango dates (32.50±0.32 Ma) compare well with conventional whole grain methods for chips of the same Durango crystal. Systematic errors in the method are expected, particularly in the pit measurement and U, Th, Sm measurement to which correction (κ-value) was applied. These Durango dates were used to produce a ҡ-value to correct the secondary reference material and unknown samples. After correction, FCT apatite yields a weighted average age of 28.37 ± 0.96 Ma, which agrees well with published data.

description: How does dynamic price information flow among Northern European electricity spot prices and prices of major electricity generation fuel sources? We use time series models combined with new advances in causal inference to answer these questions. Applying our methods to weekly Nordic and German electricity prices, and oil, gas and coal prices, with German wind power and Nordic water reservoir levels as exogenous variables, we estimate a causal model for the price dynamics, both for contemporaneous and lagged relationships. In contemporaneous time, Nordic and German electricity prices are interlinked through gas prices. In the long run, electricity prices and British gas prices adjust themselves to establish the equlibrium price level, since oil, coal, continental gas and EUR/USD are found to be weakly exogenous.

description: Event-by-event fluctuations are central to the current understanding of ultrarelativistic heavy-ion collisions. In particular, fluctuations in the geometry of the early-time collision system are responsible for new phenomena such as triangular flow, which have solved important puzzles in existing data. We propose a simple model where initial fluctuations stem from independent flux tubes randomly distributed in the transverse plane. We calculate analytically the moments of the initial anisotropies (dipole asymmetry, eccentricity, triangularity), which are the sources of anisotropic flow, and their mutual correlations. Our analytic results are in good agreement with calculations from commonly-used Monte-Carlo codes, providing a simple understanding of the fluctuations contained in these models. Any deviation from these results in future experimental data would thus indicate the presence of non-trivial correlations between the initial flux tubes and/or extra sources of fluctuations that are not present in current models.

Performance of shape memory alloy reinforced concrete frames under extreme loads
Creators: name: Moni, Moniruzzaman
Publisher: name: University of British Columbia
Year: 2012

description: Reinforced concrete (RC) frame structures are commonly used in various parts of the world for resisting lateral loads. Over the last few decades, the influence of extreme loads on structures has received much attention by researchers and practicing engineers. In RC structures steel is mainly used as reinforcing material where its major setback is associated with a high residual deformation after yielding during an extreme load event, which may often result in structural collapse or substantial damages to the structure. Superelastic shape memory alloy (SMA) is a special material, which has the ability to undergo large deformation and recover its shape upon unloading. In the present study, a numerical investigation has been carried out to determine the potential application of SMA rebar in improving the performances of reinforced concrete (RC) frames under extreme loads. Nine RC ductile moment-resisting frames of different stories (3, 6 and 8) designed as per CSA A23.3 located in western Canada are taken into consideration. For each storey type, three different reinforcement detailings have been considered, namely: i) steel reinforcement only (Steel RC); ii) SMA rebar used in the plastic hinge region of the beams and steel rebar in other regions (Steel-SMA RC); and iii) the beams fully reinforced with SMA rebar (SMA RC). For all 3 cases, the columns were reinforced with steel rebars. Nonlinear static pushover analyses, nonlinear incremental dynamic and linear dynamic time history analyses were performed on these buildings to determine the overstrength factor (Ro), ductility reduction factor (Rd) and the response modification factor (R) of the considered buildings. In addition, the supply and demand of the ductility reduction factor were also compared with different frame types. The results indicated that the code proposed response modification factors can be used for the SMA and Steel-SMA RC frames. Seismic vulnerability of the considered frames are also evaluated in terms of peak global roof drift, maximum inter-story drift, maximum residual roof drift and maximum residual inter-storey drift, which are considered as critical response parameters. In addition, the progressive collapse performances of the considered frames have been evaluated as per the General Service Administration (GSA, 2003) guideline by performing linear and nonlinear static and dynamic, analyses. The results showed that the performance of the Steel RC frame is better compared to that of the SMA RC frame under progressive collapse.

description: In our era of burgeoning knowledge and multiplying sub-specializations, to attempt interdisciplinary research is no small task. Complex global issues, new interstices of research and trends in higher education all demand inquiry across traditional departments. As many have commented, hunger, global warming, discrimination and war do not have corresponding "departments" in the academy, yet they are issues that call for the broadest possible interdisciplinary research to challenge our preconceptions and imagine new models of understanding and enact positive and sustainable practices. Like the spaces of a great cathedral, seemingly open to the infinite but firmly contained by stone pillars, the architecture of each discipline structures its particular questions and field of focus. Whether by tradition or the compatibility of specific tools to specific problems, some issues never emerge from the shadows. Philosophical differences about the nature of knowledge are among the most significant barriers to interdisciplinary research. At the same time, by crossing these barriers, traditional disciplines may expand their own field of view while lending clarity and fresh approaches to the investigations of other specialties.

description: Christopher Morse has set out to salvage "dogmatics" as a theological discipline, but a first-year seminarian might naturally wonder if her teacher isn’t dodging the big issue. The most natural question for dogmatics would seem to be: What should any individual Christian, personally, believe? Yet even the faith statements Morse eventually offers are usually stated in terms of doctrine as in "the Christian Faith" or "the church’s faith in God the Creator," and a reader is bound to wonder if these locutions aren’t more sociological than personal, presented in terms of "the deposit of faith"—the "traditioned" symbolic representations of the "social facts" associated with worship. Now it’s true that when it comes to what should not be included among those doctrines, Morse’s recommendations seem to take on a more personal aspect.

in which similar cases exist, e.g. German. In this paper we focus on discourse par-

ticles pa and že in (multiple) wh-questions and sluicing. These examples are not

only important for our understanding of sluicing but are also crucial for analyzing

description: "And what do you do?" As a graduate student studying Christian theology in a country that increasingly expects education institutions to focus primarily on the production of tech-savvy laborers, this is quite an awkward question. What role do academic theologians play in this kind of educational system? What is the task of theology in this context? In pursuing answers to these questions, I return to one of the first works on theology I studied, written by one of my first theology professors: Christopher Morse’s Not Every Spirit: A Dogmatics of Christian Disbelief. In Not Every Spirit, Morse examines the task of theology (in particular, dogmatics, that field of theology concerned with the faithfulness of claims regarding God), and rehearses the theological work he prescribes. As I will be focusing on the task of theology in this paper, I will engage with the corresponding section of Morse’s book here. Not Every Spirit begins with Morse’s claim that "to believe in God is not to believe in everything." In other words, while the emphasis in some churches may be on what ideas about God or authorities on God are to be believed, such belief necessarily implies a disbelief of other ideas and authorities. Christian faith is, then, a matter of "faithful disbelief."

description: Direct interaction with the beta subunit of the heterotrimeric G protein complex causes voltage-dependent inhibition of N-type calcium channels. To further characterize the molecular determinants of this interaction, we performed scanning mutagenesis of residues 372-387 and 410-428 of the N-type channel alpha1 subunit, in which individual residues were replaced by either alanine or cysteine. We coexpressed wild type Gbeta1gamma2 subunits with either wild type or point mutant N-type calcium channels, and voltage-dependent, G protein-mediated inhibition of the channels (VDI) was assessed using patch clamp recordings. The resulting data indicate that Arg376 and Val416 of the alpha1 subunit, residues which are surface-exposed in the presence of the calcium channel beta subunit, contribute significantly to the functional inhibition by Gbeta1. To further characterize the roles of Arg376 and Val416 in this interaction, we performed secondary mutagenesis of these residues, coexpressing the resulting mutants with wild type Gbeta1gamma2 subunits and with several isoforms of the auxiliary beta subunit of the N-type channel, again assessing VDI using patch clamp recordings. The results confirm the importance of Arg376 for G protein-mediated inhibition and show that a single amino acid substitution to phenylalanine drastically alters the abilities of auxiliary calcium channel subunits to regulate G protein inhibition of the channel.

description: Glutamate receptors, which play a major role in the physiology and pathology of central nervous system gray matter, are also involved in the pathophysiology of white matter. However, the cellular and molecular mechanisms responsible for excitotoxic damage to white matter elements are not fully understood. We explored the roles of AMPA and GluR5 kainate receptors in axonal Ca(2+) deregulation.
Broken S3 Symmetry in the Neutrino Mass Matrix and Non-Zero theta_{13}

description: We study the effects of breaking S3 symmetry in the neutrino mass matrix for the masses and mixing matrix of neutrinos. At zeroth order the model gives degenerate neutrino masses and accommodates tribimaximal mixing. We introduce perturbations in terms of a small and complex parameter. The perturbations are introduced in a manner such that the S3 symmetry is broken by its elements in the same representation. Successive perturbations introduce mass splitting, sizable non-zero reactor mixing angle and CP violation. This scheme of breaking S3 symmetry can reproduce a relatively large reactor mixing angle as suggested by the recent T2K results. The effective neutrino mass is predicted to be large which is testable in the ongoing and forthcoming neutrinoless double beta decay experiments.

description: It’s hard to overstate the importance the presence of Dr. Christopher Morse on Union Theological Seminary’s campus over the last several decades has had. The variety of articles in this special double issue of Union Seminary Quarterly Review suggest this immense importance in all the diverse ways it has been felt. Dr. Morse has served as a professor, a mentor, a preacher, and a pastor to many people who have come in and gone out Union’s doors. The articles contained within are roughly divided into sections that reflect these different roles as well as the different key aspects of Dr. Morse’s work, both in the past and present. Anyone who has taken the foundational ST 104 class during his tenure at the seminary will recognize their own experience in that class and, hopefully, fondly remember their own experiences of working through doctrines, doing dogmatics as the work of "faithful disbelief," and perhaps most of all, constructing an utrum paper. The latter is represented within, both explicitly as well as implicitly in form: indeed, it’s an exercise and a way of thinking that is critical to develop in order to have a well reasoned stance on the important issues, historically and contemporarily, in the church and theology.
Building Custom Term Suggestion Web Services with OAI-Harvested Open Data

description: The problem that the same information need can be expressed in a variety of ways is especially true for scientific literature. Each scientific discipline has its own domain-specific language and vocabulary. This language is coded into documentary tools like thesauri or classifications that are used to document and describe scientific documents. When we think of information retrieval as "fundamentally a linguistic process" (Blair, 2003) users have to be aware of the most relevant search terms - which are the controlled thesauri terms the documents are described with. This can be achieved with so-called search-term-recommenders (STR) that map free search terms of a lay user to controlled vocabulary terms which can then be used as a term suggestion or to do an automatic query expansion (Hienert, Schaer, Schaible, & Mayr, 2011). State-of-the-art repository software systems like DSpace or EPrints already offer some kind of term suggestion features in search or input forms but these implementations only work as simple auto completion mechanisms that don't incorporate any kind of semantic mapping. Such software systems would gain a lot in terms of usability and data consistency if tools like the proposed domain-specific STRs would be freely available. We aim to implement a rich toolbox of web services (like the mentioned domain-specific STRs) to support users and providers of online Digital Library (DL) or repository systems.

description: Cook's distance [Technometrics 19 (1977) 15-18] is one of the most important diagnostic tools for detecting influential individual or subsets of observations in linear regression for cross-sectional data. However, for many complex data structures (e.g., longitudinal data), no rigorous approach has been developed to address a fundamental issue: deleting subsets with different numbers of observations introduces different degrees of perturbation to the current model fitted to the data, and the magnitude of Cook's distance is associated with the degree of the perturbation. The aim of this paper is to address this issue in general parametric models with complex data structures. We propose a new quantity for measuring the degree of the perturbation introduced by deleting a subset. We use stochastic ordering to quantify the stochastic relationship between the degree of the perturbation and the magnitude of Cook's distance. We develop several scaled Cook's distances to resolve the comparison of Cook's distance for different subset deletions. Theoretical and numerical examples are examined to highlight the broad spectrum of applications of these scaled Cook's distances in a formal influence analysis.
