description: This study examined the association of social anxiety, loneliness, and problematic Internet use (PIU) with the online solicitation of minors. Within a convenience sample of adult Internet users from Germany, Finland, and Sweden (N = 2,828), we compared the responses of participants who had not interacted sexually with strangers online (n = 2,049) with participants who sexually interacted with unknown adults online (n = 642), and both groups with adults who sexually solicited unknown minors online (n = 137). Online sexual interaction with adults was associated with higher levels of social anxiety, loneliness, and PIU compared with not sexually interacting with strangers online. Sexually soliciting minors online was associated with higher levels of social anxiety, loneliness, and PIU compared with sexually interacting with adults and not sexually interacting with strangers at all. Interestingly, compared with those with adult contacts, loneliness was specifically pronounced for participants who solicited children, whereas social anxiety and PIU were pronounced for participants soliciting adolescents. These findings suggest that social anxiety, loneliness, and PIU may be among the motivators for using the Internet to solicit individuals of different age groups for sexual purposes. These factors emerged as specifically relevant for adults who sexually solicited minors and who reported greater impairments compared with adults who sexually interacted with adults. These characteristics may thus be important to consider for assessment and treatment procedures for individuals soliciting minors online.
Utility based pricing and hedging of jump diffusion processes with a view to applications

description: We discuss utility based pricing and hedging of jump diffusion processes with emphasis on the practical applicability of the framework. We point out two difficulties that seem to limit this applicability, namely drift dependence and essential risk aversion independence. We suggest to solve these by a re-interpretation of the framework. This leads to the notion of an implied drift. We also present a heuristic derivation of the marginal indifference price and the marginal optimal hedge that might be useful in numerical computations.

description: The crystal structure of cannabidiol, C21H30O2, {systematic name: 2-[(1R,6R)-3-methyl-6-(prop-1-en-2-yl)cyclo­hex-2-en­yl]-5-pentyl­benzene-1,3-diol}, was determined earlier by Jones et al. [(1977). Acta Cryst. B33, 3211–3214] and Ottersen & Rosenqvist [(1977). Acta Chem. Scand. B31, 749–755]. In both investigations, the absolute configuration is given as R,R, referring to Mechoulam et al. [(1967.J. Am. Chem. Soc. 89, 4552–4554]. In the latter, the absolute configuration was identified by chemical means. Using the advantages of modern single-crystal X-ray diffractometers such as area detectors and high-intensity radiation sources, a high-quality structure determination including the absolute configuration was possible and is shown in this work. Furthermore, the rather uncommon Cu Kβ wavelength radiation was applied for the structure determination, which confirmed the absolute structure to be R,R.

description: Sorsby's fundus dystrophy (SFD) has been mapped to a genetic interval of 8 cM between loci D22S275 and D22S278. A total of 15 families, unrelated on the basis of genealogy and expressing the SFD phenotype were identified from a large data base of genetic eye disease families originating from diverse parts of the British Isles. The identification of the same Ser181Cys mutation cosegregating with disease in each family led us to consider the hypothesis of a founder effect being present. In all families studied, the same relatively infrequent allele (occurring in just 11% of the control group) was associated with disease at marker locus D22S280. A highly significant disease-associated haplotype, spanning across 3 cM of the SFD locus, was conserved in 11 of the 15 families (68% of all affected chromosomes); a further extended haplotype spanning up to 7 cM, was identified in 5 families (27% of SFD-associated chromosomes) and possibly represents the ancestral haplotype. This haplotype analysis has refined the TIMP3 gene localization to a 1- to 3-cM interval between marker loci D22S273 and D22S281 and provides strong evidence for a single mutational event being responsible for the majority of SFD identified in the British Isles.

description: Despite enormous progress both in theoretical and experimental quantum cryptography, the security of most current implementations of quantum key distribution is still not established rigorously. One of the main problems is that the security of the final key is highly dependent on the number, M, of signals exchanged between the legitimate parties. While, in any practical implementation, M is limited by the available resources, existing security proofs are often only valid asymptotically for unrealistically large values of M. Here, we demonstrate that this gap between theory and practice can be overcome using a recently developed proof technique based on the uncertainty relation for smooth entropies. Specifically, we consider a family of Bennett-Brassard 1984 quantum key distribution protocols and show that security against general attacks can be guaranteed already for moderate values of M.

description: The tissue inhibitors of metalloproteinases (TIMPs) play a crucial role in the physiological turnover of the extracellular matrix (ECM) by tightly regulating matrix metalloproteinase (MMP) activities. Disturbances in the TIMP/MMP system have been implicated in many disease processes where loss of ECM integrity is a principal feature. More recently, we have shown that mutations in TIMP3 cause the autosomal dominant disorder Sorsby's fundus dystrophy (SFD). This is a macular degeneration disorder with characteristic ECM irregularities in Bruch's membrane. To further facilitate mutational analysis and to provide a basis for functional studies, we now report the genomic organization of the human TIMP3 gene.
What classicality? Decoherence and Bohr's classical concepts

description: Niels Bohr famously insisted on the indispensability of what he termed "classical concepts." In the context of the decoherence program, on the other hand, it has become fashionable to talk about the "dynamical emergence of classicality" from the quantum formalism alone. Does this mean that decoherence challenges Bohr's dictum -- for example, that classical concepts do not need to be assumed but can be derived? In this paper, we'll try to shed some light down the murky waters where formalism and philosophy mingle. To begin, we'll clarify the notion of classicality in the decoherence description. We'll then discuss Bohr's and Heisenberg's takes on the quantum-classical problem and reflect on the different meanings of the terms "classicality" and "classical concepts" in the writings of Bohr and his followers. This analysis will allow us to put forward some tentative suggestions for how we may better understand the relation between decoherence-induced classicality and Bohr's classical concepts.

The world is real : writing, counting, and reading in the art of Hanne Darboven
Creators: name: Stieda, Kalie
Publisher: name: University of British Columbia
Year: 2017

description: This thesis seeks to approach the work of German artist Hanne Darboven (1941-2009) through the operations of writing, counting, and reading. In the language of New German Media Theory, these operations are known as elementary cultural techniques. I will trace the thematization of these techniques by analyzing Hanne Darboven’s art through what are known as her text formulations (schreibe, beschreibe nicht, schreibe rechnen/rechne schreiben, and gedankenstrich). These formulations are all inherently tautological, an aspect which links them to the recursivity of cultural techniques. These techniques are “articulations of the real,” ontic operations that exist a priori of the ontological concepts they generate, producing a difference between established pillars of meaning. Though many critics of Darboven see her art as the evocation of transcendental concepts like history and time, my research will show that Darboven is ultimately concerned with how these operations ground her process in the fabric of the world. Darboven’s art is not a rational realization of the values of the Enlightenment, nor is it a mathematical proof with infinite variations. It is rather a recursive system that is infinite only in its repetition of its own process, which is also a personal method of coping with daily life invented by the artist.

description: We investigate a spatially flat Friedmann-Robertson-Walker (FRW) universe where dark matter exchanges energy with a self-interacting holographic dark energy (SIHDE). Using the $χ^2$--statistical method on the Hubble function, we obtain a critical redshift that seems to be consistent with both BAO and CMB data. We calculate the theoretical distance modulus for confronting with the observational data of SNe Ia for small redshift $z\leq 0.1$ and large redshift $0.1 \leq z\leq 1.5$. The model gets accelerate faster than the $Λ$CDM one and it can be a good candidate to alleviate the coincidence problem. We also examine the age crisis at high redshift associated with the old quasar APM 08279+5255.

description: Best's vitelliform macular dystrophy is an autosomal dominant disorder of unknown causes. To identify the underlying gene defect the disease locus has been mapped to an approximately 1.4-Mb region on chromosome 11q12-q13.1. As a prerequisite for its positional cloning we have assembled a high coverage PAC contig of the candidate region. Here, we report the construction of a primary transcript map that places a total of 19 genes within the Best's disease region. This includes 14 transcripts of as yet unknown function obtained by EST mapping and/or cDNA selection and five genes mapped previously to the interval (CD5, PGA, DDB1, FEN1, and FTH1). Northern blot analyses were performed to determine the expression profiles in various human tissues. At least three genes appear to be good candidates for Best's disease based on their abundant expression in retina or retinal pigment epithelium. Additional information on the functional properties of these genes, as well as mutation analyses in Best's disease patients, have to await their further characterization. [The GenBank/EMBL accession numbers and details of the isolation, localization, and characterization of ESTs and selected cDNAs are available as online supplements in Online Tables 1-3 at http://www.genome.org.]
Non-equilibrium Landauer Transport Model for Hawking radiation from a Black Hole

description: We propose that the Hawking radiation energy and entropy flow rates from a black hole can be viewed as a one-dimensional (1D), non-equilibrium Landauer transport process. Support for this viewpoint comes from previous calculations invoking conformal symmetry in the near-horizon region, which give radiation rates that are identical to those of a single 1D quantum channel connected to a thermal reservoir at the Hawking temperature. The Landauer approach shows in a direct way the particle statistics independence of the energy and entropy fluxes of a black hole radiating into vacuum, as well as one near thermal equilibrium with its environment. As an application of the Landauer approach, we show that Hawking radiation gives a net entropy production that is 50% larger than that obtained assuming standard three-dimensional emission into vacuum.

description: The influence of the amphiphile 1,3-dimethylurea (1,3-DMU) on the dynamic properties of water was studied using dielec. relaxation spectroscopy. The expt. provided evidence for substantial retardation of water reorientation in the hydration shell of 1,3-DMU, leading to a sep. slow-water relaxation in addn. to contributions from bulk-like and fast water as well as from the solute. From the amplitudes of the resolved water modes effective hydration nos. were calcd., showing that each 1,3-DMU mol. effectively freezes the reorientation of 1-2 water mols. Addnl., a significant amt. of solvent mols., decreasing from ~39 at infinite diln. to ~3 close to the soly. limit, is retarded by a factor of ~1.4 to 2.3, depending on concn. The marked increase of the solute amplitude indicates pronounced parallel dipole alignment between 1,3-DMU and its strongly bound H2O mols. Mol. dynamics (MD) simulations of selected solns. revealed a notable slowdown of water rotation for those solvent mols. surrounding the Me groups of 1,3-DMU and strong binding of ~2H2O by the hydrophilic carbonyl group, corroborating thus the exptl. results. Addnl., the simulations revealed 1,3-DMU self-aggregates of substantial lifetime.

Effects of curing modes on depth of cure and microtensile bond strength to dentin of bulk fill resin composites
Creators: name: Makhdoom, Sara Naeem
Publisher: name: University of British Columbia
Year: 2017

description: Objectives: To compare microtensile bond strength (µTBS) and depth of cure (DOC) of bulk fill composites cured by monowave (MW) and polywave (PW) LED units at different curing times. Materials and methods: Three composites were tested: Tetric EvoCeram Bulk Fill (TBF), Filtek Bulk Fill (FBF) and Tetric EvoCeram (T). Flat dentin surfaces treated with adhesive (Adhese, Ivoclar Vivadent) were bonded with cylindrical 4mm bulk composite of each material (n=6) and cured with monowave (Satelec) or polywave (Bluephase Style) curing units at 10s or 20s. After 24 hours, teeth were sectioned in individual 0.9 mm² beams and tested for µTBS. In addition, the DOC (IOS 4090) scrape test was performed (n=5) following the same curing protocols. Two-way ANOVA (=0.05) was performed isolating light curing units. Results: MW light curing unit showed no statistical significant difference in µTBS for all materials and curing times tested. Likewise, the PW light curing unit did not show differences, except for TBF. Overall, bulk fill composites presented greater DOC and longer curing time resulted in higher DOC for all composites. Conclusion: Curing mode does not result in differences in µTBS to dentin. However, bulk fill composites exhibit greater DOC than conventional resin composites.

If $p\equiv 1\pmod4$ and $p=x^2+y^2$ with $x\equiv 1\pmod4$ and $y\equiv 0\pmod2$, then we show $$\sum_{k=0}^{p-1}\frac{\binom{2k}k^2\binom{2k}{k+1}}{(-8)^k}\equiv 2p-2x^2\pmod{p^2}\ \ \mbox{and}\ \ \sum_{k=0}^{p-1}\frac{\binom{2k}k\binom{2k}{k+1}^2}{(-8)^k}\equiv-2p\pmod{p^2}$$ by means of determining $x$ mod $p^2$ via $$(-1)^{(p-1)/4}\,x\equiv\sum_{k=0}^{(p-1)/2}\frac{k+1}{8^k}\binom{2k}k^2\equiv\sum_{k=0}^{(p-1)/2}\frac{2k+1}{(-16)^k}\binom{2k}k^2\pmod{p^2}.$$ We also solve the remaining open cases of Rodriguez-Villegas' conjectural congruences on $$\sum_{k=0}^{p-1}\frac{\binom{2k}k^2\binom{3k}k}{108^k},\ \ \sum_{k=0}^{p-1}\frac{\binom{2k}k^2\binom{4k}{2k}}{256^k}, \ \ \sum_{k=0}^{p-1}\frac{\binom{2k}{k}\binom{3k}k\binom{6k}{3k}}{12^{3k}}$$ modulo $p^2$.

description: Algebraic K-theory and motivic cohomology have developed together over the last thirty years. Both of these theories rely on a mix of algebraic geometry and homotopy theory for their construction and development, and both have had particularly fruitful applications to problems of algebraic geometry, number theory and quadratic forms. The homotopy-theory aspect has been expanded significantly in recent years with the development of motivic homotopy theory and triangulated categories of motives, and K-theory has provided a guiding light for the development of non-homotopy invariant theories. 19 one-hour talks presented a wide range of latest results on many aspects of the theory and its applications.

description: We revisit the study of (A)dS black holes in Lovelock theories. We present a new tool that allows to attack this problem in full generality. In analyzing maximally symmetric Lovelock black holes with non-planar horizon topologies many distinctive and interesting features are observed. Among them, the existence of maximally symmetric vacua do not supporting black holes in vast regions of the space of gravitational couplings, multi-horizon black holes, and branches of solutions that suggest the existence of a rich diagram of phase transitions. The appearance of naked singularities seems unavoidable in some cases, raising the question about the fate of the cosmic censorship conjecture in these theories. There is a preferred branch of solutions for planar black holes, as well as non-planar black holes with high enough mass or temperature. Our study clarifies the role of all branches of solutions, including asymptotically dS black holes, and whether they should be considered when studying these theories in the context of AdS/CFT.

description: As part of the search for the Huntington disease (HD) gene we have cloned and sequenced 34 kb of genomic DNA containing the full-length gene for the β-subunit of the human cGMP phosphodiesterase (β-cGMP PDE). This gene is localized to 4p16.3 about 700 kb proximal to the 4p telomere and represents the most telomeric gene characterized on 4p to date. We show that this gene is comprised of 22 exons spanning approximately 43 kb of genomic DNA. We also provide 400 bp immediately 5′ to the putative initiator methionine and 700 bp of 3′ flanking sequences. Northern blot analysis of several human tissues revealed a highly abundant 3.5 kb transcript and a minor signal of 4.5 kb in retinal tissue. Alignment of the deduced amino acid sequence to the previously identified β-subunits of the cGMP PDEs of mouse and cow demonstrates highly significant similarities and, therefore, confirms the identity of the cloned gene. A defect in the β-subunit of the cGMP PDE gene has been shown recently to be the cause for the retinal degeneration in the rd mouse. The cloning of the human homolog and the knowledge of its genomic organization with exon/intron boundaries will allow rapid assessment of the role of this gene in the causation of human retinopathies.

By writing the Dirac equation for noncommutative Coulomb potential, we compute noncommutative corrections of the energy levels using perturbation methods and by comparing to the Lamb shift accuracy we get a bound on the parameter of non-commutativity. We use this bound to study the effects on the Lyman-α ray and by induction look the possible influence of non-commutativity on some astrophysical and cosmological phenomena.

description: Four-dimensional asymptotically flat spacetimes at spatial infinity are defined from first principles without imposing parity conditions or restrictions on the Weyl tensor. The Einstein-Hilbert action is shown to be a correct variational principle when it is supplemented by an anomalous counter-term which breaks asymptotic translation, supertranslation and logarithmic translation invariance. Poincaré transformations as well as supertranslations and logarithmic translations are associated with finite and conserved charges which represent the asymptotic symmetry group. Lorentz charges as well as logarithmic translations transform anomalously under a change of regulator. Lorentz charges are generally non-linear functionals of the asymptotic fields but reduce to well-known linear expressions when parity conditions hold. We also define a covariant phase space of asymptotically flat spacetimes with parity conditions but without restrictions on the Weyl tensor. In this phase space, the anomaly plays classically no dynamical role. Supertranslations are pure gauge and the asymptotic symmetry group is the expected Poincaré group.

description: This research explored the reporting practices related to measurement information in social and personality psychology. We investigated how often authors report measurement characteristics that are useful for assessing construct validity, and how often authors provide access to the study’s materials. We also investigated how these measurement reporting practices and the availability of materials relate to each other, and how these practices have changed from 2010 to 2020—the decade of the “replication crisis”.

description: After introducing the formalism of the general space and time fractional Schrödinger equation, we concentrate on the time fractional Schrödinger equation and present new results via the elegant language of Fox's H-functions. We show that the general time dependent part of the wave function for the separable solutions of the time fractional Schrödinger equation is the Mittag-Leffler function with an imaginary argument by two different methods. After separating the Mittag-Leffler function into its real and imaginary parts, in contrast to existing works, we show that the total probability is less than one and decays with time. Introducing the effective potential approach, we also write the Mittag-Leffler function with an imaginary argument as the product of its purely decaying and purely oscillating parts. In the light of these, we reconsider the simple box problem. PACS numbers: 03.65.Ca, 02.50.Ey, 02.30.Gp, 03.65.Db
Role of Rubrics in Higher Education: Fairness and Consistency of Students' Grading
Creators: name: Subedi, Khemraj
Publisher: name: Zenodo
Year: 2022
Subjects: Learning outcomes, student grading, consistency, holistic rubrics, analytic rubrics

description: This paper attempts to present rubrics as a guiding tool for mapping learning outcomes of students more objectively, consistently, reliably and validly. The rubrics aimed at accurate and fair assessment, fostering understanding, and indicating a way to proceed with subsequent learning/teaching to delineate consistent criteria for grading. This integration of performance and feedback is called ongoing assessment or formative assessment. Rubrics allow teachers; to summarize student performance; to tabulate student accomplishment of learning goals; to disaggregate student scores by specific criteria and skills; and, to identify patterns of strengths and weaknesses of students’ work and of the assignments themselves. They provide teachers a mechanism to score reliably, make valid judgments, and rationalize the grades awarded. Therefore, rubrics provide teachers with a greater understanding of their own teaching practice and encourage teachers to become reflective practitioners.

description: Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman coupling may allow for the creation of an inner spin-1/2 core surrounded by high-spin wings. The latter are always more entropic than the core at high temperatures and, remarkably, at all temperatures in the presence of frustration. Combining thermodynamic Bethe Ansatz with local density approximation, we study the spatial entropy distribution for the particular case of one-dimensional spin-3/2 lattice fermions in the Mott phase. Interestingly, this spatially dependent entropy opens a possible path for an adiabatic cooling technique that, in contrast to previous proposals, would specifically target the spin degree of freedom. We discuss a possible realization of this adiabatic cooling, which may allow for a highly efficient entropy decrease in the spin-1/2 core and help access antiferromagnetic order in experiments on ultracold spinor fermions.

description: We present a strategy for the cloning of DNA sequences adjacent to the tandemly repeated DNA sequence (TTAGGG)n. Sequence analysis of 14 independently isolated clones revealed the presence of non-repetitive sequences immediately adjacent to or flanked by blocks of the simple repeat (TTAGGG)n. In addition, we provide sequence information on two previously undescribed tandemly repeated sequences, including a 9 bp repeat and a modification of the (TTAGGG)n repeat. Using different mapping approaches six sub-clones, free of the TTAGGG repeat, were assigned to a single human chromosome. Moreover, in situ hybridization mapped one of these subclones, G2 - 1H, definitively to the telomeric band on chromosome 4q. However, Bal 31 insensitivity suggests a location in a more subterminal region. All the (TTAGGG)n-adjacent unique sequences tested are highly conserved among primates but are not present in other mammalian species. Identification and mapping of TTAGGG-adjacent sequences will provide a refined insight into the genomic organization of the (TTAGGG)nrepeat. The isolation of chromosome specific TTAGGG-adjacent sequences from subtelomeric regions of all human chromosomes will serve as important end points for the genetic maps and will be useful for the molecular characterization of chromosomal rearrangements involving telomeres.
Schengen, then and now : the origins and crisis of the borderless European Union.
Creators: name: Meyre, Maureen
Publisher: name: University of British Columbia

description: The recent turmoil in Italy, resulting from the arrival of thousands of refugees from the Middle East and North African Region (MENAR) in the hope of constructing a better future in Europe has demonstrated the limitations of European immigration policies and the potential weakening of the promise of integration founded on the principles of liberal institutionalism. This research therefore aims at challenging the liberal institutionalist assumption which views commitment to borderless commerce and freedom of movement made in the Single European Act (SEA) and the Schengen Agreements as essential to maintaining stability in Europe. With regards to the challenges to European unity posed by the contemporary security and refugee crises the research adopts a neorealist paradigm to answer whether liberal perspectives still contribute to the understanding of the refugee crisis since its inception in 2010. The thesis employs a qualitative, interdisciplinary approach based on a small-n sample of the ‘Big Three’ – Germany, the United Kingdom and France – to get an appreciation of the political aspirations of policy-makers and develop an understanding of how key tendencies in public opinion affect the decisionmaking processes at the national level and the balance of power at the EU-level. Since this small-n approach cannot produce knowledge generalizable to the entire European Union (EU), the research will compensate by comparing the political cultures of the ‘Big Three’ because the way they have responded to the refugee crises can at least be expected to influence the policy options pondered by other member-states. In brief, the main purpose of this research is to yield valuable insights about how the refugee crisis provoked a crystallization of public opinion between Europhiles and Eurosceptics.

description: In the present contribution, the pre-structuring of binary mixtures of hydrotropes and H2O is linked to the solubilisation of poorly water miscible compounds. We have chosen a series of short-chain alcohols as hydrotropes and benzyl alcohol, limonene and a hydrophobic azo-dye (Disperse Red 13) as organic compounds to be dissolved. A very weak pre-structuring is found for ethanol/H2O and 2-propanol/H2O mixtures. Pre-structuring is most developed for binary 1-propanol/H2O and tert-butanol/H2O mixtures and supports the bicontinuity model of alcohol-rich and water-rich domains as already postulated by Anisimov et al. Such a pre-structuring leads to a high solubilisation power for poorly water miscible components (limonene and Disperse Red, characterized by high octanol/water partition coefficients, log(P) values of 4.5 and 4.85), whereas a very weak pre-structuring leads to a high solubilisation power for slightly water miscible components (benzyl alcohol). This difference in solubilisation power can be linked to (i) the formation of mesoscale structures in the cases of ethanol and 2-propanol and (ii) the extension of pre-structures in the cases of 1-propanol and tert-butanol. Three different solubilisation mechanisms could be identified: bulk solubilisation, interface solubilisation and a combination of both. These supramolecular structures in binary and ternary systems were investigated by small-and-wide-angle X-ray and neutron scattering, dynamic light scattering and conductivity measurements (in the presence of small amounts of salt).

description: If a quantum system A, which is initially correlated to another system, E, undergoes an evolution separated from E, then the correlation to E generally decreases. Here, we study the conditions under which the correlation disappears (almost) completely, resulting in a decoupling of A from E. We give a criterion for decoupling in terms of two smooth entropies, one quantifying the amount of initial correlation between A and E, and the other characterizing the mapping that describes the evolution of A. The criterion applies to arbitrary such mappings in the general one-shot setting. Furthermore, the criterion is tight for mappings that satisfy certain natural conditions. Decoupling has a number of applications both in physics and information theory, e.g., as a building block for quantum information processing protocols. As an example, we give a one-shot state merging protocol and show that it is essentially optimal in terms of its entanglement consumption/production.

Understanding the transition to BIM for facility owners
Creators: name: Cavka, Hasan Burak
Publisher: name: University of British Columbia
Year: 2017

description: Building information modeling (BIM) is emerging as a potential solution for facility owners to address the challenges of poor information quality and interoperability during project handover and inadequate facilities management during building operations. However, implementing BIM in an owner organization is a complex challenge that necessitates reconfiguration of work practices and internal structures to fully realize the benefits. Although previous studies have documented the potential benefits of BIM adoption for owners, such as improvements in work order processing, very little research has specifically looked at the transition to BIM and the scale of the effort required for large and diverse owner organizations. This dissertation investigates the transition to BIM through the lens of two large public owner organizations in Canada. Specifically, the research involved embedded case study analyses to investigate the alignment of facilities management (FM) practices across the organizational and project contexts in relation to owner requirements. The resulting case study analysis is unique in terms of the richness of the data collection and analysis methods used, the research approach investigating alignment across two interrelated contexts at the organizational and project level, and the focus on information in terms of understanding how facility information is affected by the organizational processes, technologies and requirements. The investigation of current owner practices enabled a better understanding of the gap between available and required information, processes and technology, and the challenges owners face when considering the transition to BIM. A significant contribution resulting from these studies is the framework I developed to characterize the alignment between organizational constructs, available technology, project artifacts and owner information requirements. The research into two different owners provided a rich understanding of owners’ information requirements and led to the formalization of computable requirements in relation to BIM, and the development of a 3-stage methodology to help owners develop and deploy BIM requirements. This research demonstrates that the transition to BIM for facility owners necessitates the development of explicit and computable BIM requirements, the reconfiguration of internal work practices, and the formalization of stages of compliance to support BIM-enabled project delivery.
