description: In 2008, a cohort of Inuit researchers met in Ottawa for a two-week training course on Inuit health research and planning. A means for ongoing communication after the course was necessary to build on their acquired knowledge. Research shows that online communities of practice (OCoPs) are often unsuccessful due to factors such as a lack of time and a lack of member involvement in design of the OCoP. The objective of this research was to find the determinants that impact participation in an OCoP of members from a cohort of Inuit researchers. An open-ended interview questionnaire was developed and members were interviewed. Results show lack of time as the main barrier to participation. Involvement in the development of an updated OCoP is of interest to many members. In a culture that has been built and sustained by knowledge sharing, an OCoP is a legitimate tool.

Intensity-intensity correlations determined by dimension of quantum state in phase space: P-distribution

description: Abstract We use the P-distribution to show that the familiar values 1, 2 and 3 of the normalized second order correlation function at equal times corresponding to a coherent state, a thermal state and a highly squeezed vacuum are a consequence of the number of dimensions these states take up in quantum phase space. Whereas the thermal state exhibits rotational symmetry and thus extends over two dimensions, the squeezed vacuum factorizes into two independent one-dimensional phase space variables, and in the limit of large squeezing is therefore a one-dimensional object. The coherent state is a point in the phase space of the P-distribution and thus has zero dimensions. The fact that for photon number states the P-distribution is even narrower than that of the zero-dimensional coherent state suggests the notion of ‘negative’ dimensions.
Experiments in highly sheared, nearly homogeneous turbulence.
Creators: name: De Souza, Fenella.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Engineering, Aerospace.

description: Nearly homogeneous, uniformly sheared, turbulent flow was generated in a high speed wind tunnel at shear rates ranging from 436 to 705 s$\sp{-1}$ and Mach numbers below 0.2. The shear rates are substantially higher than those generated in the past, and comparable to those in the inner region of turbulent boundary layers. Measurements were obtained using a three-beam, two-component, laser-Doppler velocimetry (LDV) system in back-scatter mode. The system employs a 100mW Argon-Ion laser, which is connected to the measuring probe via fibre optics. Although the signal was filtered by the data acquisition system, additional computer programs were required to remove extraneous noise, which was defined as data samples beyond 2.5 standard deviations from the mean. LDV measurements show that the turbulence structure attains a self-similar state with approximately constant dimensionless stresses and exponential kinetic energy growth. The main difference from realizations at lower shear rates (comparable to those in outer boundary layers) is a marked decrease in the dimensionless Reynolds shear stress, $-K\sb $, which attained an average value of 0.11 over all present experiments, compared to the value 0.15 obtained previously in uniform shear flow and outer boundary layers. The Reynolds shear stress correlation coefficient averaged over all the present shear flows was 0.35, and was consistently lower than the value of 0.45 which has been found in outer boundary layers and uniform shear flows at lower shear rates. It was concluded that although the partition of turbulent kinetic energy among its components most likely depends on the proximity of a wall, the rate of production of turbulence in shear flow depends mainly on the rate of mean shear, irrespectively of the shear generation mechanism.

description: The spoken dialogue systems today already fulfill many requirements, and their human-machine interaction works very well. Nevertheless, the users still adapt their communication style to these system. In order to develop appropriate communication style strategies for a spoken dialogue system, we have investigated the communication style factors elaborateness and directness. Within this work, an indoor navigation spoken dialogue system was developed, which has different communication style strategies and states of knowledge implemented. Moreover, a formula for the adaptation of the system's communication style to the user's communication style was developed. The system navigates the user through the University of Ulm based on scripts. In order to create these scripts, a data collection study was carried out in which 97 participants described the selected routes with the help of videos, which have been recorded beforehand. Finally, the system was evaluated in a user study with 30 participants. In summary, the system performed good, but we could find no significant difference between the investigated communication styles. However, the different knowledge states of the system revealed some significant differences. Overall, we were able to demonstrate the potential of the indoor navigation application and gained new insights for the communication styles and the interaction with a non-omniscient system.

description: Air pollution has become a critical issue in the urban areas of southeastern China in recent years. A complete understanding of the tempo-spatial characteristics of air pollution can help the public and governmental bodies manage their lives and work better. In this study, data for six criteria air pollutants (including particulate matter (PM₂.₅, PM₁₀), carbon monoxide (CO), sulfur dioxide (SO₂), nitrogen dioxide (NO₂) and ozone (O₃)) from 37 sites in nine major cities within Fujian Province, China were collected between January 2015 to December 2016, and analyzed. We analyzed the spatial and temporal variations of these six criteria pollutants, as well as the attainment rates, and identified what were the major pollutants. Our results show that: (1) the two-year mean values of PM₂.₅ and PM₁₀ exceeded the Chinese National Ambient Air Quality Standard (CAAQS) standard I levels, whereas other air pollutants were below the CAAQS standard I; (2) the six criteria air pollutants show spatial variations (i.e. most air pollutants were higher in the city center areas, followed by suburban areas and exurban areas, except for O₃; and the concentrations of PM₁₀, PM₂.₅, NO₂, O₃ were higher in coastal cities than in inland cities); (3) seasonal variations and the no attainment rates of air pollutants were found to be higher in cold seasons and lower in warm seasons, except for O₃; (4) the most frequently present air pollutant was PM₁₀, with PM₂.₅ and O₃ being the second and third most frequent, respectively; (5) all the air pollutants, except O₃, showed positive correlations with each other. These results provide additional information for the effective control of air pollution in the province of Fujian.

description: This chapter looks at the re-emergence of an old property concept as a way of understanding the Internet’s design. Defined simply, the commons is a term to describe something that everyone owns and everyone can use. The commons has proved an important motif in theoretical and policy discussions concerned with the Internet’s architecture; in particular, how the idea of open access can encourage or restrict the development of new ideas and technologies. We map out the broader intellectual history of property and enclosure in order to see how the commons critique might apply to the Internet in Australia.
Cooling and crystallization of komatiite flows.
Creators: name: Shore, Mark.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Geology.

description: Despite their $\sim$2710 Ma age, thin komatiite lava flows in Munro township, NE Ontario have sufficiently well-preserved primary structures, textures, mineralogy, and whole-rock geochemistry to constrain the physical processes of cooling and crystal growth. Seawater convection drove a cooling and fracturing front through the upper surface and was the dominant mechanism of heat loss, leading to pronounced textural asymmetry within flows. Large plate-like crystals of olivine in the upper layers of flows grew by constrained crystallization arising from strong thermal pradients and the high lattice thermal conductivity and near-infrared transparency of olivine (3-5 times greater than that of the surrounding melt). Such crystals exhibit a very strong preferred orientation with the a crystallographic axis perpendicular to flow surfaces. Major and minor-element zoning within olivine crystals is closely modeled by fractional crystallization from the bulk liquid, and whole-rock geochemical variations within flows by crystal fractionation of highly magnesian olivine. The high chromium content of olivine is of mineralogical and technological interest, and is due to two substitutional mechanisms: $\sp{\lbrack 6\rbrack}$Cr$\sp{3+} + \sp{\lbrack 4\rbrack}$Al$\sp{3+} \rightleftharpoons\ \sp{\lbrack 6\rbrack}$Mg$\sp{2+} + \sp{\lbrack 4\rbrack}$Si$\sp{4+}$ and 2 $\sp{\lbrack 6\rbrack}$Cr$\sp{3+} + \sp{\lbrack 6\rbrack}\square \rightleftharpoons 3 \sp{\lbrack 6\rbrack}$Mg$\sp{2+}.$ Dendritic chromian spinel crystals nucleated heteroepitaxially on olivine substrates; the crystallographic relationship between the phases is (111) $\sb{\rm sp} \parallel$ (100) $\sb{\rm ol}$, (110) $\sb{\rm sp}\ \parallel$ (001) $\sb{\rm ol}\ \parallel$, and (211) $\sb{\rm sp}\ \parallel$ (010) $\sb{\rm ol}$. The Cr-spinel crystals have features typical of metallic, ionic, and organic crystal dendrites, but rarely found in minerals. Immobility of Mg and Si and a systematic loss of Ca in these altered rocks is due to a serpentinization reaction buffered by the desilication of glass or fine-grained plagioclase in the groundmass. Serpentinization occurred under conditions of low confining pressure, caused up to 30% expansion of the basal portions of flows, and predated tectonism at $\sim$2700 Ma.

description: Leaf stoichiometry (nitrogen (N), phosphorus (P) and N:P ratio) is not only important for studying nutrient composition in forests, but also reflects plant biochemical adaptation to geographic and climate conditions. However, patterns of leaf stoichiometry and controlling factors are still unclear for most species. In this study, we determined leaf N and P stoichiometry and their relationship with soil properties, geographic and climate variables for Cyclocarya paliurus based on a nation-wide dataset from 30 natural populations in China. The mean values of N and P concentrations and N:P ratios were 9.57 mg g⁻¹, 0.91 mg g⁻¹ and 10.51, respectively, indicating that both leaf N and P concentrations in C. paliurus forests were lower than those of China and the global flora, and almost all populations were limited in N concentration. We found significant differences in leaf N and P concentrations and N:P ratios among the sampled C. paliurus populations. However, there were no significant correlations between soil properties (including organic C, total N and P concentrations) and leaf stoichiometry. The pattern of variation in leaf N concentration across the populations was positively correlated with latitude (24.46° N–32.42° N), but negatively correlated with mean annual temperature (MAT); meanwhile, leaf N concentration and N:P ratios were negatively correlated with mean temperature in January (MTmin) and mean annual frost-free period (MAF). Together, these results suggested that temperature-physiological stoichiometry with a latitudinal trend hold true at both global and regional levels. In addition, the relationships between leaf stoichiometry and climate variables provided information on how leaf stoichiometry of this species may respond to climate change.

description: The Canadian firm of Jacques & Hay was in business for fifty years, during which the company, if The Globe (Toronto) is to be believed, furnished the Province of Canada. This was a stunning and largely undocumented success. Jacques & Hay was one of the largest employers in the province and dominated the cabinet-making trade from 1835 to 1885. In 1871, Jacques & Hay employed 430 men and 50 women in a vertically-integrated operation that included a sawmill, two factories and a showroom. Jacques & Hay produced abundant furniture at reasonable prices. The availability of such household furnishings greatly enhanced domestic life in nineteenth-century Canada, providing scope for a more elaborate social life and allowing more people to achieve a greater sense of comfort and decency in their living arrangements. In addition, Jacques & Hay created the wood interiors for St. James' Cathedral, the Toronto Normal School, University College and Osgoode Hall. The company also supplied the majority of the furnishings for Rideau Hall, Ottawa and Government House, Toronto. While the story of the Jacques & Hay firm throws light on the opportunities Victorian craftsmen had to become manufacturers, it also explains the company's role in making furniture more accessible and contributing to nineteenth-century notions of progress and civility.

Raising the Dead: Finding History in the Gospel Accounts of Jesus's Resurrection Miracles Part One: The Synoptic Tradition
Creators: name: Scott, Steven Richard
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Religion, General.
subject: Religion, Biblical Studies.

description: This thesis is an historical analysis of Jesus's resurrection miracles in the synoptic tradition, namely, the stories of the raising of Jairus's daughter (Mark 5:21--43 and par.) and the widow of Nain's son (Luke 7: 11--17), and the story of the exorcism of a possessed boy (Mark 9:14--29 and par.), which can be considered a raising-of-the-dead story only in the Gospel of Mark. The analysis done in this thesis differs from other analyses in that it takes seriously both the oral and written nature of the gospels and the traditions behind them. The analysis also differs in that it uses a different historical framework: it works from a position of a very high Christology, frequent communication between Christian centres, and a definite authority structure within the early Christian community from its beginning. These items all affect how one will view the control of the oral tradition, which in turn will affect how one will analyse the differences between the synoptic versions of the stories of Jairus's daughter and the possessed boy, and how one will judge the fact that the story of the widow of Nain's son is found only in Luke. In regards to the written nature of the gospels, it is argued that the primary structuring device used by the gospel authors is chiastic (concentric) in nature. To demonstrate this a new statistical method for judging chiasms has been developed. A large section of Mark (1: 12--6:46) is divided into both longer and shorter units, and then the parallels---both word and conceptual--- between each unit and all the other units are noted. This data is then not only used to judge the level of parallelism between units, but also to perform probability calculations on found chiastic structures. The demonstration of chiastic structures is useful in analysing possible redactional changes the gospel authors may have made to the Jesus tradition in order to create their chiasms. Also, because chiastic structures can impart meaning, elements that may have been added for theological reasons are also highlighted. The result of both the oral and chiastic analyses is a completely new methodology for judging the historicity of the Jesus tradition.

description: Background Oesophageal cancer (EC) is the sixth leading cause of cancer death worldwide. Oesophageal resection is the only curative treatment option for EC which is frequently performed via an abdominal and right thoracic approach (Ivor-Lewis operation). This 2-cavity operation is associated with a high risk of major complications. To reduce postoperative morbidity, several minimally invasive techniques have been developed that can be broadly classified into either hybrid oesophagectomy (HYBRID-E) via laparoscopic/robotic abdominal and open thoracic surgery or total minimally invasive oesophagectomy (MIN-E). Both, HYBIRD-E and MIN-E, compare favourable to open oesophagectomy. However, there is still an evidence gap comparing HYBRID-E with MIN-E with regard to postoperative morbidity. Methods The MICkey trial is a multicentre randomized controlled superiority trial with two parallel study groups. A total of 152 patients with oesophageal cancer scheduled for elective oesophagectomy will be randomly assigned 1:1 to the control group (HYBRID-E) or to the intervention group (MIN-E). The primary endpoint will be overall postoperative morbidity assessed via the comprehensive complication index (CCI) within 30 days after surgery. Specific perioperative parameters, as well as patient-reported and oncological outcomes, will be analysed as secondary outcomes. Discussion The MICkey trial will address the yet unanswered question whether the total minimally invasive oesophagectomy (MIN-E) is superior to the HYBRID-E procedure regarding overall postoperative morbidity.

description: Vaccinarsi contro il morbillo provoca l'autismo? Questa domanda ha provocato un dibattito acceso, che ha visto schierati i sostenitori della scienza "ufficiale", da una parte, e gli “alternativi”, dall'altra. Per gli uni, pubblicare su riviste scientifiche edite da importanti editori internazionali, che selezionano gli articoli sulla base di una selezione compiuta da esperti anonimi è un marchio di validità. Per gli altri, l'intero sistema, dalle riviste di proprietà di editori importanti, ma commerciali, fino alle industrie farmaceutiche che mirano al profitto, è viziato da conflitto di interessi. Come può orientarsi, qui, chi desidera sapere, senza essere ricercatore di professione? Un articolo recente del matematico Timothy Gowers ci aiuterà a rispondere con gli strumenti della scienza aperta – strumenti che non servono a prendere partito ma a partecipare alla discussione come persone che pensano da sé e non come clienti di maghi.

description: We obtained ALMA spectroscopy and deep imaging to investigate the origin of the unexpected sub-millimeter emission toward the most distant quiescent galaxy known to date, ZF-COSMOS-20115 at z = 3.717. We show here that this sub-millimeter emission is produced by another massive (M∗∼ 1011 MȮ), compact (r1-2 = 0.67 ± 0.14 kpc) and extremely obscured galaxy (AV ∼ 3.5), located only 0.43′′ (3.1 kpc) away from the quiescent galaxy. We dub the quiescent and dusty galaxies Jekyll and Hyde, respectively. No dust emission is detected at the location of the quiescent galaxy, implying SFR < 13 MȮ yr-1 which is the most stringent upper limit ever obtained for a quiescent galaxy at these redshifts. The two sources are spectroscopically confirmed to lie at the same redshift thanks to the detection of [C II]158 in Hyde (z = 3.709), which provides one the few robust redshifts for a highly-obscured "H-dropout" galaxy (H - [4.5] = 5.1 ± 0.8). The [C II] line shows a clear rotating-disk velocity profile which is blueshifted compared to the Balmer lines of Jekyll by 549 ± 60 km s-1, demonstrating that it is produced by another galaxy. Careful de-blending of the Spitzer imaging confirms the existence of this new massive galaxy, and its non-detection in the Hubble images requires extremely red colors and strong attenuation by dust. Full modeling of the UV-to-far-IR emission of both galaxies shows that Jekyll has fully quenched at least 200Myr prior to observation and still presents a challenge for models, while Hyde only harbors moderate star-formation with SFR ∼120 MȮ yr-1, and is located at least a factor 1.4 below the z ∼ 4 main sequence. Hyde could also have stopped forming stars less than 200 Myr before being observed; this interpretation is also suggested by its compactness comparable to that of z ∼ 4 quiescent galaxies and its low [C II]/FIR ratio, but significant on-going star-formation cannot be ruled out. Lastly, we find that despite its moderate SFR, Hyde hosts a dense reservoir of gas comparable to that of the most extreme starbursts. This suggests that whatever mechanism has stopped or reduced its star-formation must have done so without expelling the gas outside of the galaxy. Because of their surprisingly similar mass, compactness, environment and star-formation history, we argue that Jekyll and Hyde can be seen as two stages of the same quenching process, and provide a unique laboratory to study this poorly understood phenomenon.

description: Relying on the optical properties of apple tissue for nondestructive quality or maturity prediction requires a detailed understanding of the dependence on its structure and ongoing physiological processes. In this study, a multispectral spatial frequency domain imaging (SFDI) setup was used to investigate local changes in the effective scattering coefficient µ's and absorption coefficient µa related to vascular bundles or heterogeneous starch distribution. Weekly measurements during the maturation period for the cultivars `Elstar', `Gala', `Jonagold', and `Braeburn' allowed further study of how different ripening processes affect the scattering and absorption properties. The results show both a characteristic location-dependent decrease of µ's between the cortex and core region of up to 30 % and an additional temporal decrease of up to 35 % during maturation. The absolute changes depended strongly on the respective cultivar. In general, transport structures such as vascular bundles led to a local decrease of µ's in combination with an increased absorption in the spectral regions that can be attributed to water and chlorophyll b. To our knowledge, it was demonstrated for the first time that the presence of starch granules in the cortex of immature apples had a significant effect on µ's, associated with an increase of up to 60 %. Based on the temporal development of µa, the buildup and degradation of important plant pigments in the cortex during the maturation period could be traced. At a wavelength of 656 nm, a decrease in chlorophyll content and at 447 nm, an increase in carotenoid content was observed upon reaching ripeness. Thus, SFDI proved capable of providing deeper insight into the heterogeneous optical properties of apple tissue and linking these properties to physiological variables. Part 2 of this study investigates the observed effects from a theoretical point of view based on a Mie model considering microstructural properties.

description: Twelve streams of the Ottawa-Hull area were sampled between May 9, 1990 and August 1, 1991 to examine how benthic macroinvertebrate biomass and size spectra varied in relation to periphyton biomass. Among sites, non-filter-feeding macroinvertebrate biomass is correlated positively to periphyton biomass. This relation is defined by the regression equation: Log(BNF) = 1.64 + 0.41*Log(peri) (r$\sp2$ = 0.50, F = 9.9, p = 0.01, S$\sp2$ = 0.15, n = 12). The logarithm of the mean annual periphyton biomass explains 50% of the variance encountered in the logarithm of the mean annual non-filter-feeding macroinvertebrate biomass. This figure goes up to 70% if only samples collected between mid-July and mid-August are considered. The normalized size spectra of all benthic macroinvertebrates from city streams is shifted to the right along the abcissa compared to the normalized size spectra of other streams. This shift indicates a greater individual average weight for macroinvertebrates in city streams compared to macroinvertebrates from Gatineau Park. This shift is not solely related to the eutrophic level of the stream. Other studies in controlled environments will be needed to determine the cause of this shift.

description: he possibility of using hexagonal structures in general, and graphene in particular, to emulate the Dirac equation is the topic under consideration here. We show that Dirac oscillators with or without rest mass can be emulated by distorting a tight-binding model on a hexagonal structure. In the quest to make a toy model for such relativistic equations, we first show that a hexagonal lattice of attractive potential wells would be a good candidate. Firstly, we consider the corresponding one-dimensional (1D) model giving rise to a 1D Dirac oscillator and then construct explicitly the deformations needed in the 2D case. Finally, we discuss how such a model can be implemented as an electromagnetic billiard using arrays of dielectric resonators between two conducting plates that ensure evanescent modes outside the resonators for transversal electric modes, and we describe a feasible experimental setup

description: Background: There is limited information on neurochemical markers being used to support and monitor the affection of motoneurons in patients with spinal muscular atrophy (SMA). The objective of this study was to examine neurochemical markers in cerebrospinal fluid (CSF) under treatment with the antisense-oligonucleotide (ASO), nusinersen. Methods: We measured markers of axonal degeneration [neurofilament light chain (NfL) and phosphorylated neurofilament heavy chain (pNfH)] along with basic CSF parameters in 25 adolescent and adult SMA type 2 and 3 patients at baseline and after four intrathecal injections of nusinersen. Neurochemical markers were compared with controls. In addition, neurochemical markers in SMA patients were related to the Hammersmith Functional Rating Scale Expanded (HFMSE). Results: No significant difference in neurofilament (Nf) values was observed between SMA and control group, neither at baseline nor after four injections of nusinersen. NfL, protein and quotients of albumin (Qalb) increased slightly in SMA patients after the fourth injection. The slight increase of NfL could be related to the development of mild CSF flow change. No relations were observed between changes in Nf and HFMSE. Conclusion: We assume that Nf levels in CSF in these patients may result from slow disease progression in this stage of disease, pre-existing loss of motoneurons due to long disease duration besides affection of the LMN only. Therefore, we conclude that Nf levels in CSF do not seem useful as diagnostic and monitoring markers in adolescent and adult SMA type 2 and 3 patients.

description: Due to the low demand for conventional annuities, alternative retirement products are sought. Quite recently, tontines have been frequently brought up as a promising option in this respect. Inspired by unit-linked life insurance and retirement products, we introduce unit-linked tontines in this article, where the tontine payoffs are directly linked to the development of the underlying financial market. More specifically, we consider two different tontine payoff structures differing in the (non-)inclusion of guaranteed payments. We first price the unit-linked tontines by using the risk-neutral pricing approach. Consequently, we study the attractiveness of these products for a utility-maximizing policyholder and compare them with non-unit-linked tontines. Our numerical analysis sheds light on the design challenges and gives explanations why similar products might not be widely adopted already.

description: Incontinence is a common yet under-recognized issue that impacts quality of life, especially for older adults in whom there is often a multifactorial etiology. A retrospective chart review was performed on a representative sample of patients seen at our multidisciplinary continence clinic in Vancouver, Canada from January to December 2017 inclusive. Initial assessment was performed by the nurse continence advisor (NCA) or geriatrician depending on the source of referral. The pelvic floor physiotherapist (PFP) could then be consulted based on perceived need. The average age at assessment was 76 years old (range 29–102), with 82% of patients ≥65 years and 27% ≥85 years old. The majority of patients were referred for bladder incontinence (72%), with the remaining patients referred for bowel incontinence (28%) or pessary care (7%). Referrals came from a variety of sources including physicians (62%), nurses (22%), allied health care providers (12%) and self-referral (5%). Multimorbidity was common, with 40% of patients having a Charlson Comorbidity Index ≥6. The same proportion of patients (40%) were on ≥5 prescription medications. Many patients were functionally dependent for either instrumental activities of daily living (52%) or activities of daily living (25%). Non-pharmacologic treatments were commonly recommended, with the majority of patients counselled on lifestyle changes (88%) and taught Kegel exercises (70%). For patients seen by the geriatrician, modifications were made to non-continence medications in 50% of cases and medical comorbidities were optimized in 39% of cases. In terms of pharmacologic therapy, over-the-counter (OTC) medications were initiated in 45% of patients whereas continence-specific prescription medications were started in 17% of patients. A multidisciplinary continence clinic can play an important role in promoting successful aging by assessing and treating medical causes of incontinence in medically complex older adults.

description: We have used the Hubble Space Telescope's Advanced Camera for Surveys to measure the mass density function of morphologically-selected early-type galaxies in the Gemini Deep Deep Survey fields, over the redshift range 0.9 < z < 1.6. Our imaging data set covers four well-separated sight-lines, and is roughly intermediate (in terms of both depth and area) between the GOODS/GEMS imaging data, and the images obtained in the Hubble Deep Field campaigns. Our images contain 144 galaxies with ultra-deep spectroscopy, and they have been analyzed using a new purpose-written morphological analysis code which improves the reliability of morphological classifications by adopting a image thresholding technique. We find that at z = 1 approximately 70% of the stars in massive galaxies reside in early-type systems. This fraction is remarkably similar to that seen in the local Universe. However, we detect very rapid evolution in this fraction over the range 1.0 < z < 1.6, suggesting that in this epoch the strong color-morphology relationship seen in the nearby Universe is beginning to fall into place.

A formal framework for workflow type and instance changes under correctness constraints

description: The capability to rapidly adapt in-progress workflows (WF) is an essential requirement for any workflow system. Adaptations may concern single WF instances or a WF type as a whole. While changes of single instances often have to be applied in an ad-hoc manner, type changes become necessary to adapt to evolving business processes. Especially for long-running processes it is indispensable to propagate type changes to running instances as well. Very challenging in this context is to correctly adapt a (potentially large) collection of WF instances, which may be in different states and to which various ad-hoc changes may have been previously applied. This paper presents a comprehensive framework for the support of both, WF type and WF instance changes. We establish general correctness principles and show how WF instances can be automatically and efficiently migrated to a modified WF schema. We point out that our approach exceeds existing adaptation models in formal foundation, completeness, and usability.

The acquisition of double-gapped relatives in Chinese: Grammar and processing
Creators: name: Cao, Xuexin
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Language, Linguistics.

description: This dissertation is an acquisition study of double-gap relatives in Chinese, developed under the thesis of subject-object asymmetry as postulated in Huang (1984). Two sets of act-out experiments were conducted. The first experiment tested covert-binder relatives, i.e. double gap relatives with the binder of their non-head EC unmentioned in the sentence. This type of relative was presented in two contexts: pragmatically neutral vs. biased conditions. Assuming that in the absence of pragmatic bias there is a requirement for the head of a double gap relative to be construed as the object of the relative, it was speculated that the provision of a topic NP might produce a swing towards the head of the relative being construed as the relative subject. Under this speculation, it was predicted that there would be a higher proportion of subject interpretation of the relative head in the pragmatically enriched condition than in the neutral condition. The second experiment is a follow-up, testing overt-binder relative, i.e. double gap relatives with either an overt matrix subject or topic as a potential binder of their non-head EC of the relative. The prediction here was that while a subject interpretation of the head for a subject-binder relative should be linguistically blocked, the head of a topic-binder relative was allowed to be interpreted either as the null subject or as the null object of the relative. The main result is that there is a general preference for construing the head as the null object for both covert- and overt-binder relatives. An additional finding is that the younger children, but not the older children, show some sensitivity to context, giving more object construals under the enriched condition. Huang's account is not supported by the data. The general preference for the head as null object is explained in terms of an independently attested principle of sentence processing: empty categories are always identified as soon as possible in on line coreference assignment (e.g. Nicol & Swinney, 1989; Gibson, 1998). Young children's sensitivity to the enriched context calls for future work in the field of acquisition and processing.
