description: The way companies create service-oriented value is changing as organizational boundaries blur towards value creation in ecosystems. To position themselves strategically, practitioners need to understand the different roles in service-oriented value creation systems (SOVCS). Still, there is no evidence if existing role models can be applied for SOVCS. This paper analyses the adequacy of existing strategic role models for service-oriented business ecosystems. The suitability of the role models is evaluated using central aspects of the Service-Dominant Logic. We demonstrate that the existing central strategic role models cannot be transferred to a SOVCS and outline the research need for an adequate strategic role model. Scholars will find an overview of existing role models and use the conducted evaluation as a foundation for further service science research. Based on the identified inaccessibility, a comprehensive strategic positioning model can be developed.

description: We consider an interacting particle system in continuous configuration space. The pair interaction has an attractive part. We show that, at low density, the system behaves approximately like an ideal mixture of clusters (droplets): we prove rigorous bounds (a) for the constrained free energy associated with a given cluster size distribution, considered as an order parameter, (b) for the free energy, obtained by minimising over the order parameter, and (c) for the minimising cluster size distributions. It is known that, under suitable assumptions, the ideal mixture has a transition from a gas phase to a condensed phase as the density is varied; our bounds hold both in the gas phase and in the coexistence region of the ideal mixture. The present paper improves our earlier results by taking into account the mixing entropy.

description: Mid-level ethanol/gasoline blends can provide knock resistance benefits for stoichiometric spark-ignition engine operation, but previous studies have identified challenges associated with spray impingement and wall wetting, leading to excessive particulate matter emissions. At the same time, stratified-charge spark-ignition operation can provide increased thermal efficiency, but care has to be exercised to avoid excessive in-cylinder soot formation. In support of the use of mid-level ethanol/gasoline blends in advanced spark-ignition engines, this study presents spray and fuel-film measurements in a direct-injection spark-ignition engine operated with a 30 vol.%/70 vol.% ethanol/gasoline blend (E30). Crank-angle resolved fuel-film measurements at the piston surface are conducted using two different implementations of the refractive index matching technique. A small-angle refractive index matching implementation allows quantification of the wetted area, while a large-angle refractive index matching implementation enables semi-quantitative measurements of fuel-film thickness and volume, in addition to fuel-film area. The fuel-film measurements show that both the amount of fuel deposited on the piston and the shape of the fuel-film patterns are strongly influenced by the injection timing, duration, intake pressure, and coolant temperature. For combinations of high in-cylinder gas density and long injection duration, merging of the individual spray plumes, commonly referred to as spray collapse, can cause a dramatic change to the shape and thickness of the wall fuel films. Overall, the study provides guidance to engine designers aiming at minimizing wall wetting through tailored combinations of injection timings and durations.

description: In a recent article, Arendt and ter Elst have shown that every sectorial form is in a natural way associated with the generator of an analytic strongly continuous semigroup, even if the form fails to be closable. As an intermediate step they have introduced so-called j-elliptic forms, which generalises the concept of elliptic forms in the sense of Lions. We push their analysis forward in that we discuss some perturbation and convergence results for semigroups associated with j-elliptic forms. In particular, we study convergence with respect to the trace norm or other Schatten norms. We apply our results to Laplace operators and Dirichlet-to-Neumann-type operators.

description: In this paper, we present the first comprehensive survey of window types for stream processing systems which have been presented in research and commercial systems. We cover publications from the most relevant conferences, journals, and system whitepapers on stream processing, windowing, and window aggregation which have been published over the last 20 years. For each window type, we provide detailed specifications, formal notations, synonyms, and use-case examples. We classify each window type according to categories that have been proposed in literature and describe the out-of-order processing. In addition, we examine academic, commercial, and open-source systems with respect to the window types that they support. Our survey offers a comprehensive overview that may serve as a guideline for the development of stream processing systems, window aggregation techniques, and frameworks that support a variety of window types.

description: Competitive differentiation in the manufacturing sector is no longer based on product and service innovations alone but on the ability to monetize the usage phase of products and services. To this end, manufacturers are increasingly looking at so-called subscription business models as a way of supplementing the traditional sale of products and services. Since supplier success in the subscription business is directly dependent on customer success, the setup and expansion of a so-called Customer Success Management (CSM) is required. While CSM has already been established in the software industry for several years, companies in the manufacturing sector are often still in the conceptual phase of a CSM, parallel to the setup and expansion of their subscription business. Therefore, this paper aims to support the set-up of a CSM by providing a reference data model, based on case study research, that can be used to support the organizational or daily CSM tasks and to serve as a blueprint for conceptualizing CSM-specific IT systems.

description: Platform workers can typically not take their ratings from one platform to another. This creates lock-in as building up reputation anew can come at prohibitively high cost. A system of portable reputation may mitigate this problem but poses several new challenges and questions. This study reports the results of an online experiment among 180 actual clients of five gig economy platforms to disentangle the importance of two dimensions of worker reputation: (1) contextual fit (i.e., the ratings’ origin from the same or another platform) and (2) contentual fit (i.e., the ratings’ origin from the same or a different job type). By and large, previous work has demonstrated the potential of imported ratings for trust-building but usually confounded these two dimensions. Our results provide a more nuanced picture and suggest that there exist two important boundary conditions for reputation portability: While imported ratings can have an effect on trust, they may only do so for matching job types and in the absence of within-platform ratings.
Impact of prenatal screening on future resource utilization in pregnancy

description: In 2007, the Society of Obstetricians and Gynaecologists of Canada first recommended that prenatal screening for fetal aneuploidy be offered to all pregnant women. This is an important change in clinical obstetrics as previously these services had only been routinely offered to women who would be 35 or older at the time of delivery; however, maternal age alone is a poor predictor of fetal aneuploidy. Obtaining reliable data on prenatal screening utilization is problematic in Canada as these data are not collected in a systematic way nationally and, in many cases, not even provincially. This study aimed to understand utilization of prenatal screening in an Albertan context; to examine the impact of different prenatal screening strategies on health care utilization in pregnancy; and to estimate the incremental cost of prenatal screening when accounting for all of direct medical costs of this procedure including ancillary service use. Data on health resource utilization that occurred in the three months prior to pregnancy, during pregnancy and three months post-partum were collected from twelve unique clinical and administrative databases. Using deterministic linkage, participants from multiple databases were linked based on personal health number, gender and date of birth. This study found that utilization of prenatal screening tends to impact utilization of prenatal diagnostic services but not overall health resource utilization, and that there is a cost for prenatal screening but this cost may be less than what is suggested in the literature due to differences between hypothetical utilization patterns and actual resource utilization. It also suggests that current techniques used to identify women who have an increased risk of carrying a fetus with aneuploidy, may also be useful for identifying women who are at an increased risk of a variety of adverse pregnancy outcomes. With the rapid development of non-invasive prenatal testing, additional clinical changes in prenatal screening and diagnosis are likely to occur in the next few years. However, prior to abandoning screening in favour of non-invasive prenatal testing, the results of this work suggest that a more thorough evaluation of the impact of prenatal screening on non-aneuploidy outcomes may be warranted.

description: Introduction: Pharmacy value-added services (PVAS) has been implemented in Malaysian public hospitals, facilitating the balance medications collection. Past studies examined the satisfaction towards PVAS and its impact on the waiting time. This study aimed to explore the patient's awareness of PVAS, adoption of PVAS, satisfaction towards PVAS, and willingness to adopt PVAS.  Methodology: We conducted a cross-sectional study on Miri Hospital patients by using convenience sampling. We developed and validated a questionnaire in the Malay language to gather information on respondent's demographic data, awareness of PVAS, adoption of PVAS, satisfaction towards PVAS, and willingness to adopt PVAS. The results presented descriptively.  Results:  A total of 398 respondents participated. Most respondents (70.1%) were aware that PVAS offered in Miri Hospital. However, only a third had experience using PVAS. The most commonly used PVAS was the Appointment Card Dispensing System (49.6%), while minor usage was Local Partial Medication Supply Service (2.4%). Drive-Through Pharmacy had the most incredible satisfaction score, 4.40 (SD=0.70), whereas Call-and-Collect Service was the least satisfied, 3.88 (SD=0.91). The majority of the respondents (86.2%), precisely 95.8% of the experienced PVAS user and 90.1% of the inexperienced group, were willing to adopt PVAS.  Discussion/Conclusion:  Many respondents were aware of PVAS. However, the adoption could be further improved. Furthermore, many were willing to adopt PVAS. The Drive-thru Pharmacy had the most significant awareness and satisfaction, yet low usage probably due to the lack of promotion. Adoption of PVAS is possible if we inculcate the intention to adopt.

Comprehensive numerical study of microfluidic fuel cells
Creators: name: Ebrahimi Khabbazi, Ali
Publisher: name: University of British Columbia
Year: 2010

description: The microfluidic fuel cell or laminar flow-based fuel cell is a membraneless fuel cell which typically consists of two electrodes mounted within a T- or Y-shaped microchannel. Aqueous fuel and oxidant are introduced from the two inlets of the channel and flow together side-by-side toward the end of the channel. The Reynolds number in the microchannel is low, and hence viscous forces are dominant over the inertial forces. This causes the anolyte and catholyte form a co-laminar flow inside the microchannel which is required to maintain the separation of the fuel and oxidant and limit the reactions to the appropriate electrodes. In this work, a comprehensive numerical model of the microfluidic fuel cell is developed using COMSOL Multiphysics. This model accounts for the mass and momentum transport phenomena inside the device as well as the electrochemical reaction kinetics which are described by the Butler-Volmer equations. Potential equations are used to model both the ionic conduction in the electrolyte and the electrical conduction in the solid electrodes. The validity of the developed model is first checked by verifying it against the numerical and experimental results previously reported in the literature. The model is then used to assess the effect of different modifications, which have been applied on the microfluidic fuel cell since its advent, by calculating the polarization curves associated with each modification. In this thesis, a novel design of microfluidic fuel cell with a tapered channel is also proposed. Using the numerical model, it is shown that the tapered geometry improves the fuel utilization by up to four times in addition to a substantial improvement in the power density. A similar numerical model is developed to study the performance of a microfluidic fuel cell with flow-through porous electrodes. Using this model, the effect of porosity on the net power output of the fuel cell is investigated and an optimum value for porosity is calculated. The model presented is a valuable tool, as it can be used to study the effect of any modifications on the cell performance before fabricating and testing the new design in an extensive experimental study.

description: A non-perturbative construction of the 3-point fermion-boson vertex which obeys its Ward-Takahashi or Slavnov-Taylor identity, ensures the massless fermion and boson propagators transform according to their local gauge covariance relations, reproduces perturbation theory in the weak coupling regime and provides a gauge independent description for dynamical chiral symmetry breaking (DCSB) and confinement has been a long-standing goal in physically relevant gauge theories such as quantum electrodynamics (QED) and quantum chromodynamics (QCD). In this paper, we demonstrate that the same simple and practical form of the vertex can achieve these objectives not only in 4-dimensional quenched QED (qQED4) but also in its 3-dimensional counterpart (qQED3). Employing this convenient form of the vertex \emph{ansatz} into the Schwinger-Dyson equation (SDE) for the fermion propagator, we observe that it renders the critical coupling in qQED4 markedly gauge independent in contrast with the bare vertex and improves on the well-known Curtis-Pennington construction. Furthermore, our proposal yields gauge independent order parameters for confinement and DCSB in qQED3.

This approach allows to combine slow light regime together with self-collimation in photonic crystal superlattices presenting an extremely low filling ratio in air.

subject: Arts-Informed

description: This qualitative dissertation provides an autobiographical exemplar of emergent, arts-informed inquiry, inspired by the viewing of an abstract painting that prompted a question, “What is the right red?” The topic of the right red presents a cross-disciplinary research focus within the scope of adult learning to demonstrate the potential learning that occurs when viewing art or phenomena, such as the colour red. This research employs interpretive analysis, adult learning theory, artistic research, critical reflection, and survey responses by artists and adult learners and introduces the concept of the moment of inertia. The moment of inertia—when a viewer hesitates to consider what he or she sees and what it means—is presented as a learning moment. From the viewpoint of a learner, a viewer may ask questions that lead to new insights, or meaning perspectives. The goal of this research is to encourage adult educators and adult learners, particularly those in formal learning environments, to recognize and engage moments of inertia as learning opportunities.

description: Statistically distinguishing between phase-coherent and noncoherent chaotic dynamics from time series is a contemporary problem in nonlinear sciences. In this work, we propose different measures based on recurrence properties of recorded trajectories, which characterize the underlying systems from both geometric and dynamic viewpoints. The potentials of the individual measures for discriminating phase-coherent and noncoherent chaotic oscillations are discussed. A detailed numerical analysis is performed for the chaotic Rössler system, which displays both types of chaos as one control parameter is varied, and the Mackey-Glass system as an example of a time-delay system with noncoherent chaos. Our results demonstrate that especially geometric measures from recurrence network analysis are well suited for tracing transitions between spiral- and screw-type chaos, a common route from phase-coherent to noncoherent chaos also found in other nonlinear oscillators. A detailed explanation of the observed behavior in terms of attractor geometry is given.

description: An investigation of the interaction between the in-cylinder flow and the spray topology in two spray-guided direct injection optical engines is reported. The bulk flow field in the combustion chamber is characterized using particle image velocimetry. Geometrical parameters such as the axial penetration and the spray angle of the liquid spray are measured using Mie scatter imaging and/or diffuse back-illumination. The measured parameters are compared with data from a constant volume chamber available in the literature. For a late injection strategy, the so-called ECN Spray G standard condition, the mean values of the spray penetration do not seem to be significantly perturbed by the in-cylinder flow motion until the plumes approach the piston surface. However, spray probability maps reveal that cycle-to-cycle fluctuations of the spatial distribution of the liquid spray are affected by the magnitude of the in-cylinder flow. Particle image velocimetry during injection shows that the flow field in the vicinity of the spray plumes is heavily influenced by air entrainment, and that an upward flow in-between spray plumes develops. Consistent with previous research that demonstrated the importance of the latter flow structure for the prevention of spray collapse, it is found that increased in-cylinder flow magnitudes due to increased intake valve lifts or engine speeds enhance the spray-shape stability. Compared with cases without injection, the influence of the spray on the in-cylinder flow field is still noticeable approximately 2.5 ms after the start of injection.

description: Quantum theory has an epistemic horizon, i.e. exact values cannot be assigned simultaneously to incompatible physical quantities. As shown by Spekkens' toy theory, positing an epistemic horizon akin to Heisenberg's uncertainty principle in a classical mechanical setting also leads to a plethora of quantum phenomena. We introduce a deterministic theory - nomic toy theory - in which information gathering agents are explicitly modelled as physical systems. Our main result shows the presence of an epistemic horizon for such agents. They can only simultaneously learn the values of observables whose Poisson bracket vanishes. Therefore, nomic toy theory has incompatible measurements and the complete state of a physical system cannot be known. The best description of a system by an agent is via an epistemic state of Spekkens' toy theory. Our result reconciles us to measurement uncertainty as an aspect of the inseparability of subjects and objects. Significantly, the claims follow even though nomic toy theory is essentially classical. This work invites further investigations of epistemic horizons, such as the one of (full) quantum theory.

Prohormone processing in pancreatic islet transplantation
Creators: name: Klimek, Agnieszka Magdalena
Publisher: name: University of British Columbia
Year: 2010

description: Islet transplantation is a promising treatment for diabetes; however, most transplant recipients exhibit progressive loss of graft function. Islet function in transplant recipients shares similarities with subjects with type 2 diabetes including impaired glucose-stimulated insulin secretion, decreased beta-cell mass associated with amyloid formation, and defective proinsulin processing resulting in disproportionate secretion of intact proinsulin and proinsulin intermediates. We hypothesized that processing of the beta-cell prohormones, proinsulin and pro-islet amyloid polypeptide (proIAPP), will be impaired in islet transplant recipients as in patients with type 2 diabetes. Human islet transplant recipients were found to have impaired proinsulin processing manifest as elevated proinsulin/C-peptide ratios (TP/CP). The TP/CP ratio was significantly elevated in both islet allo- and auto-transplant recipients relative to controls. Furthermore, the TP/CP was greater in those recipients that received sub-optimal numbers of islets transplanted, suggesting that beta-cell dysfunction is exacerbated in the face of increased secretory demand due to insufficient islet mass. In a mouse model of islet transplantation, proinsulin processing was found to decline over time following transplantation, resulting in elevated proinsulin/insulin ratios. Amyloid deposits, a common pancreatic lesion in type 2 diabetes, were also found in human islet transplants and were associated with reduced beta-cell mass. Since IAPP, like insulin, is also processed within the beta cell from its precursor proIAPP, and since proinsulin processing is impaired in islet transplants and type 2 diabetes, we hypothesized that proIAPP processing will also be impaired in these conditions. To quantify proIAPP levels in humans, an immunoassay was developed. Circulating proIAPP levels in normal subjects were found to be in the low picomolar range and the ratio of proIAPP/IAPP was approximately 30%. In a small cohort of type 2 diabetic subjects, the proIAPP/IAPP ratio tended to be lower. These studies demonstrate that impaired proinsulin processing is a characteristic of transplanted islets and that the proinsulin/insulin or proinsulin/C-peptide ratios may serve as markers of graft dysfunction in islet transplantation. In addition, the proIAPP/IAPP ratio can now also be evaluated as a marker of beta-cell dysfunction in islet transplants and type 2 diabetes.

description: Introduction: A survey shown that the knowledge level of safe handling cytotoxic drugs precaution among staffs in Hospital Sultanah Nur Zahirah (HSNZ) was moderate. Medication errors due to improper handling of cytotoxic drugs were also reported in HSNZ in the recent years. This study was proposed to investigate the impact of pharmacists' educational program (PEP) on knowledge and attitude of nurses handling cytotoxic drugs. Methodology: This quasi-experimental study involved nurses who handle cytotoxic drugs in HSNZ. They were selected through non-randomized universal sampling and required to answer a self-administered questionnaire for knowledge and attitude assessment. PEP was introduced by implementing continuous nursing education session which focusing on cytotoxic drugs handling. The pre and post assessments took place before and three months after the intervention. Data was analysed using descriptive and non-parametric tests with p<0.05 was considered statistically significant.  Results: 94 nurses were enrolled (female= 97.9%, mean age of 36.3±4.93 years old, mean duration involvement with cytotoxic drugs handling of 3.6±4.23 years). After the intervention, the mean knowledge score of nurses was increased from 54.4±12.64 to 59.7±11.53 (p<0.001). In term of attitude, lesser nurses able to tolerate a certain level of improper practice among their peers (reduced from 96.8% to 86.2%, p<0.05).  Discussion / Conclusion: This study suggested that the PEP has positive impacts on knowledge and attitude of nurses in handling cytotoxic drugs. PEP should be carried out regularly in hospital as part of initiatives towards reducing medication errors among nurses.

description: Professional learning communities and assessment for learning have been proven to have significant impact on student learning. However, what still remains unclear is why these practices are not resulting in improved student learning the way research has indicated. The intent of this descriptive case study was to determine what schools and school divisions were doing to aide teachers in embracing these two practices. This study examined the following question, In what ways does a professional learning community support and enable teachers to implement assessment for learning within their daily practice?, within the context of the two sites that were being studied. Four educators from two different schools in the provinces of Alberta and Saskatchewan took part in the research. From this study seven findings were revealed. The findings include: • time was not provided to collaboratively discuss student learning; • discussions about students focused on student behavior as opposed to student learning and teacher actions; • support and follow through was minimal at best; • participants could not identify the essential work of a PLC or key elements of assessment for learning. The research utilized triangulation of data through participant observations, in-depth interviews and physical artefacts. The following conclusions were attained using a Findings, Interpretations and Conclusions Matrix: • teachers were not able to change their philosophical beliefs because the PLC framework was not present; • collaborative time must be protected like instructional time; • teachers must be held accountable for their discussions and actions around student learning; • participants were not utilizing observations, conversations and products to gain a more accurate account of student learning; and • leadership is critical if the PLC framework and assessment for learning is to have any impact on teacher practices.

description: We have studied the polarization characteristics and Faraday rotation of the extragalactic radio source J17204$-$3554, that appears projected on the north lobe of the galactic H II region NGC 6334A. From observations made with the Very Large Array at 6.0 and 3.6 cm in three different epochs (1994, 1997, and 2006), we estimate a rotation measure of +5100$\pm$900 rad m$^{-2}$ for the extragalactic source. This large rotation measure implies a line-of-sight average magnetic field of $B_\parallel \simeq +36\pm6$ $μ$G, the largest obtained by this method for an H II region. NGC 6334A is significantly denser than other H II regions studied and this larger magnetic field is expected on the grounds of magnetic flux conservation. The ratio of thermal to magnetic pressure is $\sim$5, in the range of values determined for more diffuse H II regions.

description: A large forward-backward asymmetry in $t\bar t$ production, for large invariant mass of the $t\bar t$ system, has been recently observed by the CDF collaboration. Among the scalar mediated mechanisms that can explain such a large asymmetry, only the t-channel exchange of a color-singlet weak-doublet scalar is consistent with both differential and integrated $t\bar t$ cross section measurements. Constraints from flavor changing processes dictate a very specific structure for the Yukawa couplings of such a new scalar. No sizable deviation in the differential or integrated $t\bar t$ production cross section is expected at the LHC.

description: Building on the idea of a pentapyridine ligand, the Piers group has recently focused on the development of a family of boron-substituted pentadentate ligands (B2Pz4Py). This work will describe the expansion of preliminary research completed by Dr. Denis Spasyuk, involving newly synthesized cobalt complexes coordinated with a dianionic pentadentate phenyl-substituted diborate ligand. Instead of continuing with the phenyl-substituted ligand, the synthetic procedure for the ligand was adapted to make a tolyl-substituted version. The synthesis and characterization of cobalt(II) complexes and their propensity to bind O2 forming a binuclear μ-peroxo cobalt(III) complex was explored. The binding of oxygen was found to be reversible and that the O2 was activated towards protonation and that reduction of the products lead back to cobalt(II). The relevance of this chemistry to the Oxygen Reduction Reaction (ORR) was discussed. The catalytic ability of the complex to reduce oxygen was measured and preliminary results showed comparable activity to the previously studied oxygen reduction cobalt catalysts.

description: The quantum states of two laser pulses---coherent states---are never mutually orthogonal, making perfect discrimination impossible. Even so, coherent states can achieve the ultimate quantum limit for capacity of a classical channel, the Holevo capacity. Attaining this requires the receiver to make joint-detection measurements on long codeword blocks, optical implementations of which remain unknown. We report the first experimental demonstration of a joint-detection receiver, demodulating quaternary pulse-position-modulation (PPM) codewords at a word error rate of up to 40% (2.2 dB) below that attained with direct-detection, the largest error-rate improvement over the standard quantum limit reported to date. This is accomplished with a conditional nulling receiver, which uses optimized-amplitude coherent pulse nulling, single photon detection and quantum feedforward. We further show how this translates into coding complexity improvements for practical PPM systems, such as in deep-space communication. We anticipate our experiment to motivate future work towards building Holevo-capacity-achieving joint-detection receivers.

description: We obtain approximations for the time-independent Gross-Pitaevskii (GP) and complex GP equation in two and three spatial dimensions by generalizing the divergence-free WKB method. The results include an explicit expression of a uniformly valid approximation for the condensate density of an ultracold Bose gas confined in a harmonic trap that extends into the classically forbidden region. This provides an accurate approximation of the condensate density that includes healing effects at leading order that are missing in the widely adopted Thomas-Fermi approximation. The results presented herein allow us to formulate useful approximations to a range of experimental systems including the equilibrium properties of a finite temperature Bose gas and the steady-state properties of a 2D nonequilibrium condensate. Comparisons between our asymptotic and numerical results for the conservative and forced-dissipative forms of the GP equations as applied to these systems show excellent agreement between the two sets of solutions thereby illustrating the accuracy of these approximations.

description: Cumberland Peninsula, Nunavut, exposes Archean and Paleoproterozoic metamorphic rocks that are part of the Paleoproterozoic Trans-Hudson Orogen. Six metamorphic zones are present on Cumberland Peninsula. A central elongate domain, called the Touak-Sunneshine metamorphic low (TSML), contains nested muscovite+staurolite+chlorite, muscovite+andalusite, and muscovite+sillimanite zones, and parallels both regional strike and the margin of several granite-granodiorite plutons of the Qikiqtarjuaq plutonic suite. A K-feldspar+sillimanite zone constitutes much of the peninsula. Cordierite+garnet and orthopyroxene zones are spatially associated with Qikiqtarjuaq plutonic suite intrusions. To determine pressure-temperature conditions of the abundant migmatitic rocks on Cumberland Peninsula, an in-depth assessment of the application of phase diagram techniques to heterogeneous anatectic migmatitic samples was performed via thermodynamic simulations. The results pertain to migmatites in general. Key results include: the peak temperature can be recovered if just the composition of the melanosome is used to constrain the phase diagram; and temperature estimates from sample compositions comprising a combination of melanosome and leucosome can lead to over- or under-estimates of peak temperature by −25 to 50 °C. Peak metamorphic conditions on Cumberland Peninsula ranged from <4.0kbar, 545–560◦C in the muscovite+staurolite+chlorite zone to 5.6–7.6 kbar, 700–730 °C in the K-feldspar+sillimanite zone to 4.8–6.8 kbar, 730–820 °C in the cordierite+garnet and orthopyroxene zones. Microstructures indicate low-pressure metamorphism in the TSML occurred after an early deformation event and before the two dominant phases of penetrative deformation, whereas metamorphism in the K-feldspar+sillimanite zone, and locally elsewhere, was synchronous with and possibly outlasted penetrative deformation. Garnet zoning patterns and U-Pb monazite ages suggest that Cumberland Peninsula was affected by two metamorphic events. First, intrusion of the Qikiqtarjuaq plutonic suite in the northern part of the peninsula resulted in 1897 ± 8 to 1880 ± 8 Ma contact metamorphism, manifested in outwardly nested metamorphic zones. Second, 1871 ± 7 to 1853 ± 3 Ma regional metamorphism variably overprinted the entire Peninsula. Cumberland Peninsula is interpreted to have been part of the southern margin of the Rae craton, which was the upper plate in a convergent tectonic setting by ca. 1.89 Ga, before colliding with a smaller crustal block by ca. 1.87 Ga.
