Essays on banking
Creators: name: Wong, Kit P.

description: This dissertation contains three essays which look at the role of price competition in banking. The method of investigation is a theoretical one. The first two essays examine the relative efficiency of relationship banking and price banking. The third essay discusses the determination of bank interest margin. Conventional wisdom suggests that increased interbank competition should improve social welfare and thus price banking should dominate relationship banking. Essay one shows that the opposite result may occur when the product market is imperfect and the lending instruments are loan commitments. Under relationship banking both banks and borrowers have bargaining power. The borrowers have substantial bargaining power when the costs of switching banks are small. In this case, it pays the banks to charge interest rates below the competitive rates in order to keep their customers. The interest losses are compensated for by higher commitment fees paid upfront by the borrowers. Since interest costs are lower under relationship banking than under price banking, borrowers produce more and output price declines. Social welfare thus unambiguously increases. Essay two goes on to examine the relative efficiency of relationship banking and price banking under the asset substitution problem. The bank-customer relationship is assumed to provide a credible commitment for a borrower to refrain from transacting with other banks. The outcome under relation-ship banking is second-best since underinvestment results in solving the asset substitution problem. The multilateral credit transactions permitted by price banking impose negative externalities to existing loans by inducing the borrower to substitute riskier project. More underinvestment is needed to resolve the dual incentive problem and equilibrium results in reduced welfare for borrowers. Essay three tackles the determination of bank interest mar-gins using a simple production-based model of risk-neutral banks which face (i) loan default risk, (ii) interest rate risk, (iii) capital regulation, and (iv) deposit insurance. The optimal bank interest margin is shown to be increasing with the variability of the short-term money market rate, but decreasing with either a stiffer capital requirement or an increase in the flat-rate deposit insurance premium.

description: We report about recent progress in computing four-loop massive correlators. The expansion of these correlators in the external momentum leads to vacuum integrals. The calculation of these vacuum integrals can be used to determine Taylor expansion coefficients of the vacuum polarization function and decoupling functions in perturbative Quantum chromodynamics. New results at four-loop order for the lowest Taylor expansion coefficient of the vacuum polarization function and for the decoupling relation are presented.

description: Renormalization-group methods in soft-collinear effective theory are used to perform the resummation of large perturbative logarithms for deep-inelastic scattering in the threshold region x->1. The factorization theorem for the structure function F_2(x,Q^2) for x->1 is rederived in the effective theory, whereby contributions from the hard scale Q^2 and the jet scale Q^2(1-x) are encoded in Wilson coefficients of effective-theory operators. Resummation is achieved by solving the evolution equations for these operators. Simple analytic results for the resummed expressions are obtained directly in momentum space, and are free of the Landau-pole singularities inherent to the traditional moment-space results. We show analytically that the two methods are nonetheless equivalent order by order in the perturbative expansion, and perform a numerical comparison up to next-to-next-to-leading order in renormalization-group improved perturbation theory.

description: The study analyzes the cross-linking of urban and rural regions in terms of synergies between electric energy supply from renewables and electric energy demand by taking the example of a German energy region. The cooperation between a German medium-sized city, the City of Osnabrück, and its neighboring rural municipalities, Landkreis Osnabrück and Kreis Steinfurt, is evaluated regarding a joint regional electric energy supply. Real self-sufficiency degrees resulting from residual load profiles are analyzed for different scenarios. Cross-linking the city with its rural neighbors leads to higher possible self-sufficiency rates within the urban area. As to the rural regions, self-sufficiency decreases compared to considering them as single regions. The rural municipality Landkreis Osnabrück, e.g., achieves 68% real self-sufficiency with respect to its 2030 renewable energy targets and without considering storage. Cross-linkage with the City of Osnabrück results in a decrease to 60% while at the same time from the perspective of the City of Osnabrück self-sufficiency increases from 27 to 60%.

description: We have designed a two-stage, 10-step process to give organisations a method to analyse small local energy systems (SLES) projects based on their Cyber Physical System components in order to develop future-proof energy systems. SLES are often developed for a specific range of use cases and functions, and these match the specific requirements and needs of the community, location or site under consideration. During the design and commissioning, new and specific cyber physical architectures are developed. These are the control and data systems that are needed to bridge the gap between the physical assets, the captured data and the control signals. Often, the cyber physical architecture and infrastructure is focused on functionality and the delivery of the specific applications. But we find that technologies and approaches have arisen from other fields that, if used within SLES, could support the flexibility, scalability and reusability vital to their success. As these can improve the operational data systems then they can also be used to enhance predictive functions If used and deployed effectively, these new approaches can offer longer term improvements in the use and effectiveness of SLES, while allowing the concepts and designs to be capitalised upon through wider roll-out and the offering of commercial services or products.

description: This work is a comprehensive investigation of the Yang-Mills condensate (YMC) dark energy (DE) model, which is extended to include the 3-loop quantum corrections. We study its cosmic evolution and the possibility of crossing phantom divide $w=-1$, examine in details the Hubble parameter $H$, the deceleration parameter $q$, the statefinder diagnosis $(r,s)$, and the $w-w^\prime$ diagnosis of the model without and with interaction, and compare our results with other DE models. Besides, by using the observational data of type Ia supernovae (SNIa), the shift parameter from cosmic microwave background (CMB), and the baryon acoustic oscillation (BAO) peak from large scale structures (LSS), we give the cosmological constraints on 3-loop YMC model. It is found that the model can naturally solve the coincidence problem, and its prediction of the afore-mentioned parameter is much closer to the $Λ$CDM model than other dynamics DE models; the introduction of the matter-DE interaction will make the YMC model deviating from the $Λ$CDM model, and will give an equation of state (EOF) crossing -1. Moreover, it is also found that, to fit the latest SNIa data alone, the $Λ$CDM model is slightly better than the 3-loop YMC model; but in fitting of the combination of SNIa, CMB and LSS data, the 3-loop YMC model performs better than the $Λ$CDM model.

description: In observational studies designed to estimate the effects of interventions or exposures, such as cigarette smoking, it is desirable to try to control background differences between the treated group (e.g., current smokers) and the control group (e.g., never smokers) on covariates $X$ (e.g., age, education). Matched sampling attempts to effect this control by selecting subsets of the treated and control groups with similar distributions of such covariates. This paper examines the consequences of matching using affinely invariant methods when the covariate distributions are ``discriminant mixtures of proportional ellipsoidally symmetric'' (DMPES) distributions, a class herein defined, which generalizes the ellipsoidal symmetry class of Rubin and Thomas [Ann. Statist. 20 (1992) 1079--1093]. The resulting generalized results help indicate why earlier results hold quite well even when the simple assumption of ellipsoidal symmetry is not met [e.g., Biometrics 52 (1996) 249--264]. Extensions to conditionally affinely invariant matching with conditionally DMPES distributions are also discussed.

description: The dynamics of driven spin boson model is studied analytically by means of the perturbation approach based on a unitary transformation. We gave the analytical expression for the population difference and coherence of the two level system. The results show that in the weak driven case, the population difference present damped coherent oscillation (single or double frequency) and the frequencies depend on the initial state. The coherence exhibit damped oscillation with Rabi frequency. When driven field is strong enough, the population difference exhibit undamped large-amplitude coherent oscillation. The results easily return to the two extreme cases without dissipation or without periodic driven.

The movie is analyzed by the social semiotic method which gives prominence to sexist behaviors and assumptions. Because of poststructuralist gender approach, the research emphasizes the stereotypical gender categorization. The aim of this study is to develop children, teachers and parents critical literacy, in order to understand the animated films as an acquisitive product and discern the ideological conventions that are involved.
Η συσχέτιση των υποτροπών της στενωτικής τενοντοελυτρίτιδας τύπου de Quervain με τα υπερηχογραφικά χαρακτηριστικά του πρώτου διαμερίσματος του καρπού.

description: Η νόσος de Quervain είναι η στενωτική τενοντοελυτρίτιδα του πρώτου διαμερίσματος των εκτεινόντων του καρπού. Στόχος της παρούσας μελέτης είναι η μελέτη συγκεκριμένων υπερηχογραφικών χαρακτηριστικών των ασθενών με νόσο de Quervain ως προγνωστικών παραγόντων για την υποτροπή της νόσου μετά από συντηρητική θεραπεία. Τα χαρακτηριστικά υπό μελέτη είναι το εμβαδόν των τενόντων του πρώτου διαμερίσματος, ο αριθμός των τενόντων του πολλαπλασιασμένου μακρού απαγωγού τον αντίχειρα, η ύπαρξη διαφράγματος στο πρώτο διαμέρισμα και οι ενδοτενόντιες αλλοιώσεις. Μελετήθηκαν 16 καρποί ασθενών. Συμπέρασμα των ευρημάτων είναι ότι μετά από υπερηχογραφικό έλεγχο, η πιθανότητα αποτυχίας της συντηρητικής αγωγής στη νόσο de Quervain αυξάνεται 15 φορές με την ύπαρξη διαφράγματος και έξι φορές με κάθε επιπλέον τένοντα του μακρού απαγωγού. Η πληροφορία αυτή είναι χρήσιμη για τον κλινικό ιατρό, διότι μπορεί να επιλέξει εξαρχής τη χειρουργική αντιμετώπιση, αποφεύγοντας τις επιπλοκές της συντηρητικής θεραπείας όταν αυτή θεωρείται πολύ πιθανόν να αποτύχει. Οι παράμετροι των ενδοτενόντιων αλλοιώσεων και του εμβαδού των τενόντων δε σχετίζονται σημαντικά με την πιθανότητα υποτροπής.
description: De Quervain’s disease is the stenotic tenosynovitis of the first dorsal compartment of the wrist. The aim of this study was to study the correlation of de Quervain’s tenosynovitis recurrence after conservative treatment with the ultrasonographic features of the first compartment of the wrist. The features studied were the tendons’ surface, the number of tendon slips of the abductor pollicis longus, subcompartmentalization within the first compartment and intratendinous degeneration. Sixteen wrists were studied. Conclusions of the study were that the probability of recurrence increases 15 times with septum existence and six times for every additional abductor pollicis longus tendon slip. This information is useful for the clinician, because he can choose first-line operative treatment if the recurrence after conservative treatment is very likely, thus avoid the related complications. Intratendinous degeneration and tendon surface had no correlation with the recurrence of the disease.
Genetic and molecular analysis of mutations in the unc-52 gene of Caenorhabditis elegans, and isolation of a suppressor, sup-38
Creators: name: Gilchrist, Erin J.
Publisher: name: University of British Columbia
Year: 2008

description: Mutations in the unc-52 gene in Caenorhabditis elegans have been grouped into four categories based on their mutant phenotypes and complementation patterns. Class 1 mutations result in gradual paralysis beginning in the late larval stages or early in adulthood. Animals homozygous for these alleles also exhibit gonadal disorganization which is reflected in their small and variable brood sizes. Class 2 mutations cause complete paralysis of the embryo, and developmental arrest at the two-fold stage of embryogenesis. The class 3 allele also results in arrest at the two-fold stage of development but these animals are not paralyzed, inspite of having disorganized muscle. Class 1 and class 3mutations complement one another, although both of them fail to complement the class 2 alleles. Class 4 alleles of unc-52were isolated as intragenic suppressors of class 1 mutations and confer a novel phenotype upon homozygous worms. These animals do not move as well as wild-type animals, and when their body wall muscle cells are examined using polarized light microscopy, they appear much thinner and more fragile than those of wild-type animals. Molecular examination of the different mutations has revealed that several of the class 1alleles are clustered in an exon near the 3' end of the gene, and that the class 3 mutation is located at the 5' end of theunc-52 locus. All the class 4 mutations are point mutations which eliminate the splice acceptor site of the intron upstream of the class 1 mutations. The unc-52 gene has been cloned and sequenced and is homologous to the vertebrate basement membrane component, perlecan. In an effort to examine the role of this basement membrane protein in muscle function, I have isolated intergenic suppressors of the class 1 unc-52 mutants. The suppressors are all alleles of a novel gene, sup-38. Animals homozygous for these suppressor mutations exhibit mild muscle abnormalities and severe to mild gonadal disorganization. Loss-of-function alleles of sup-38 were also isolated. These mutations are maternal-effect lethal, and they do not affect normal muscle structure or function.

description: Using the APEX sub-millimeter telescope we have investigated the 12CO(3-2) emission in five face-on nearby barred spiral galaxies, where three of them are high surface brightness galaxies (HSBs) lying at the Freeman limit, and two are low surface brightness galaxies (LSBs). We have positive detections for two of three HSB spirals and non-detections for the LSBs. For the galaxies with positive detection (NGC0521 and PGC070519), the emission is confined to their bulges, with velocity dispersions of ~90 and ~73 km/s and integrated intensities of 1.20 and 0.76 K/km/s, respectively. For the non-detections, the estimated upper limit for the integrated intensity is ~0.54 K/km/s. With these figures we estimate the H2 masses as well as the atomic-to-molecular mass ratios. Although all the galaxies are barred, we observe 12CO(3-2) emission only for galaxies with prominent bars. We speculate that bars could dynamically favor the 12CO(3-2) emission, as a second parameter after surface brightness. Therefore, secular evolution could play a major role in boosting collisional transitions of molecular gas, such as 12CO(3-2), especially in LSBs.

description: The Alesker-Poincare pairing for smooth valuations on manifolds is expressed in terms of the Rumin differential operator acting on the cosphere-bundle. It is shown that the derivation operator, the signature operator and the Laplace operator acting on smooth valuations are formally self-adjoint with respect to this pairing. As an application, the product structure of the space of SU(2)- and translation invariant valuations on the quaternionic line is described. The principal kinematic formula on the quaternionic line is stated and proved.

Για το λόγο αυτό, κρίνεται απαραίτητη η ακαδημαϊκή και κοινωνική στήριξη τους. Για να επιτευχθούν, όμως, τέτοιες υποστηρικτικές δράσεις είναι αναγκαίο να αναδειχθούν τα προβλήματα και η έλλειψη στήριξης που αντιμετωπίζουν τα άτομα με οπτική αναπηρία κατά τη φοίτησή τους στο πανεπιστήμιο, κάτι το οποίο αποτελεί τον κύριο στόχο της παρούσας έρευνας. Στην έρευνά μας συμμετείχαν δώδεκα νέοι με οπτική αναπηρία, εννιά άντρες και τρεις γυναίκες, οι οποίοι φοιτούν στην τριτοβάθμια εκπαίδευση. Για την πραγματοποίηση της επιλέχθηκε η ποιοτική προσέγγιση και συγκεκριμένα η ημιδομημένη συνέντευξη. Η ανάλυση του υλικού των συνεντεύξεων πραγματοποιήθηκε με την ποιοτική ανάλυση περιεχομένου με τη χρήση της επαγωγικής προσέγγισης. Σύμφωνα με τα συμπεράσματα της έρευνας, οι συμμετέχοντες τόνισαν πολύ περισσότερο τις δυσκολίες φοίτησης απ’ ό,τι τις δυσκολίες στις σχέσεις με τους συνομηλίκους. Σε αντίθεση με τη σχετική βιβλιογραφία, οι φοιτητές υποστήριξαν πως οι βλέποντες συμφοιτητές τους πραγματοποιούν, συνήθως, το πρώτο βήμα για τη δημιουργία κοινωνικών επαφών. Τέλος, παρά το ότι λειτουργούν κέντρα ειδικών υπηρεσιών στήριξης στα ελληνικά πανεπιστήμια, σύμφωνα με τα αποτελέσματα της έρευνας μας, οι συμμετέχοντες δε γνωρίζουν καν την ύπαρξή τους.
description: The visually impaired individuals face restrictions during their studies in higher education and therefore the majority of them doesn’t choose to study in the university. For this reason their academic and social support is necessary. In order to achieve such supportive actions, it is necessary to identify the problems and the lack of support that these people face during their studies in the university which is the main objective of this research. Twelve young people with visual impairment participated in the research, nine men and three women who study in the higher education. In order to carry out this research the qualitative approach has been chosen and specifically the semi-structured interview. The analysis of the material of the interviews was performed with the qualitative content analysis using the inductive approach. According to the research findings, the participants identified the studying difficulties way more than the problems in social relations. In contrast to the literature, the students supported that their sighted classmates take the initiative for the creation of social relations. Finally, despite the special support services operating in Greek universities, according to the findings of our research, the participants have no knowledge of their existence.

Για το σκοπό αυτό, έγινε ποιοτική ανάλυση των δεδομένων με τη χρήση ημι-δομημένων συνεντεύξεων και χρησιμοποιήθηκε η ερμηνευτική φαινομενολογική ανάλυση των δεδομένων (Interpretative Phenomenological Analysis). Τα αποτελέσματα περιλαμβάνουν αρχικά, την εμπειρία του θρήνου της αδελφικής απώλειας στην παιδική ηλικία, τις ανάγκες των πενθούντων αδελφών οι οποίες παραγνωρίστηκαν από το περιβάλλον, τις αλλαγές που επέφερε η απώλεια σε προσωπικό και οικογενειακό επίπεδο, την προσπάθεια διαχείρισης της κατάστασης και τέλος το νόημα που έχει αποκτήσει η εμπειρία στην ενήλικη ζωή.
description: The present study aimed to explore the experience of sibling loss in childhood. Specifically, the present research design focused on the comprehension of subjective experience of people who have lost their sibling in childhood, the way in which this particular experience formed over time, and the meaning narrated today. The sample of the study was five individuals, of which four women and one man, from 21 to 54 years of age. All of them have experienced the loss of their brother or sister during their childhood. For this purpose, the present study used qualitative analysis of the data and applied Interpretative Phenomenological Analysis (IPA). Results include the experience of grief after the loss of a sibling during the childhood years, the needs of bereaved siblings which were disregarded, changes that followed the loss in private and family level, the effort to manage the situation and the meaning that this whole experience acquired at present.

description: The spectra of the t-U and t-t'-U Hubbard models are investigated in the one-loop approximation for different values of the electron filling. It is shown that the four-band structure which is inherent in the case of half-filling and low temperatures persists also for some excess or deficiency of electrons. Besides, with some departure from half-filling an additional narrow band of quasiparticle states arises near the Fermi level. The dispersion of the band, its bandwidth and the variation with filling are close to those of the spin-polaron band of the t-J model. For moderate doping spectral intensities in the new band and in one of the inner bands of the four-band structure decrease as the Fermi level is approached which leads to the appearance of a pseudogap in the spectrum.

description: This paper attempts to investigate the investors’ reactions to announcements related to the inclusion and deletion of companies from a widely used index of medium capitalization, using the methodology of event study analysis. The aim of this effort is to determine if the existence and the size of the price reaction varies, depending on whether the inclusion or deletion of shares is parallel, with deletion or inclusion from an upper or lower capitalization index. The hypothesis testing, was carried out in a sample of mid-cap companies events from 2000 to 2012 and based on the mid and small capitalization indices FTSE-ASE 40 and FTSE-ASE 80.
Validation: Conceptual versus Activity Diagram Approaches

description: A conceptual model is used to support development and design within the area of systems and software modeling. The notion of validation refers to representing a domain in a model accurately and generating results using an executable model. In UML specifications, validation verifies the correctness of UML diagrams against any constraints and rules defined within the model. Currently, significant research has been conducted on generating test sets to validate that UML diagrams conform to requirements. UML activity diagrams are a specific focus of such efforts. An activity diagram is a flexible instrument for describing a system s behaviors and the internal logic of complex operations. This paper focuses on the notion of validation using activity diagrams and contrasts that process with a proposed method that involves an informal validation procedure. Accordingly, this informal validation involves comparing requirements to specifications expressed by a diagram of a modeling language called thinging machine (TM) modeling. The informal validation is a type of model checking that requires the model to be small enough for the verification to be done in a limited space or time period. In the proposed method, the model diagram is divided into subdiagrams to achieve this purpose. We claim the TM behavioral model comes with a particular dispositional structure that allows a designer to carve a model into smaller components for informal validation, which is shown through two case studies.

description: We show that the recently introduced label propagation method for detecting communities in complex networks is equivalent to find the local minima of a simple Potts model. Applying to empirical data, the number of such local minima was found to be very high, much larger than the number of nodes in the graph. The aggregation method for combining information from more local minima shows a tendency to fragment the communities into very small pieces.

Who shall remain nameless?makers and collectors in MOA’s Nuu-chah-nulth basketry collection
Creators: name: Garvey, Charlene
Publisher: name: University of British Columbia
Year: 2009

description: This thesis grew out of a close examination of the UBC Museum of Anthropology Nuu-chah-nulth basketry collection and the related information about it held by the Museum. While examining the Museum’s documentation of this collection it became evident that the Museum had records of the names of most of the collectors of these baskets but the Museum had few records which identified the makers of the baskets. This paper examines the documents surrounding the Nuu-chah-nulth basketry collection as artifacts in their own right. It explores why certain forms of information (in this case the names of the collectors) became associated with a group of objects while other forms of information (the names of the makers) were not. It suggests that the ideological frameworks reflected in the colonial foundations of both private and museum collecting and the interpenetrating categories of “Primitive Art”, “Tourist Art” and “Women’s Arts”/”Crafts” have produced a system of values whereby certain objects and forms of information were deemed to be of greater importance than others. It concludes that the increasing number of makers who are being identified in recent years at this Museum signals shifts in the above mentioned categories as they are criticized and reinterpreted and it also reflects changes in the relationships between collectors, museums, and the peoples from whom their collections originate.
Triggered star formation in the Magellanic Clouds

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss how tidal interaction between the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the Galaxy triggers galaxy-wide star formation in the Clouds for the last ~0.2 Gyr based on our chemodynamical simulations on the Clouds. Our simulations demonstrate that the tidal interaction induces the formation of asymmetric spiral arms with high gas densities and consequently triggers star formation within the arms in the LMC. Star formation rate in the present LMC is significantly enhanced just above the eastern edge of the LMC's stellar bar owing to the tidal interaction. The location of the enhanced star formation is very similar to the observed location of 30 Doradus, which suggests that the formation of 30 Doradus is closely associated with the last Magellanic collision about 0.2 Gyr ago. The tidal interaction can dramatically compress gas initially within the outer part of the SMC so that new stars can be formed from the gas to become intergalactic young stars in the inter-Cloud region (e.g., the Magellanic Bridge). The metallicity distribution function of the newly formed stars in the Magellanic Bridge has a peak of [Fe/H] ~ -0.8, which is significantly lower than the stellar metallicity of the SMC.

description: In their Comment [arXiv:2102.03842], Haas et al. advance two hypotheses on the nature of the shape transformations observed in surfactant-stabilized emulsion droplets, as the theoretical models that us [Phys. Rev. Lett. 126, 038001 (2021)] and others [P. A. Haas et al. Phys. Rev. Lett. 118, 088001 (2017), Phys. Rev. Research 1, 023017 (2019)] have introduced to account for these observations. (1) Because of the different surfactants used in experimental studies, the physical mechanisms underpinning the shape transformations may, in fact, differ in spite of the extraordinary resemblance in the output. (2) The theoretical models are mathematically equivalent by virtue of the small magnitude of the stretching and gravitational energies. In this Reply, we argue that neither of these hypotheses is well justified.

description: In order to understand the parameters of the standard model of electroweak and strong interactions (coupling constants, masses, mixing angles) one needs to embed the standard model into some larger theory that accounts for the observed values. This means some additional sector is needed that fixes and stabilizes the values of the fundamental constants of nature. In these lecture notes we describe in nontechnical terms how such a sector can be constructed. Our additional sector is based on rapidly fluctuating scalar fields that, although completely deterministic, evolve in the strongest possible chaotic way and exhibit complex behaviour. These chaotic fields generate potentials for moduli fields, which ultimately fix the fundamental parameters. The chaotic dynamics can be physically interpreted in terms of vacuum fluctuations. These vacuum fluctuations are different from those of QED or QCD but coupled with the same moduli fields as QED and QCD are. The vacuum energy generated by the chaotic fields underlies the currently observed dark energy of the universe. Our theory correctly predicts the numerical values of the electroweak and strong coupling constants using a simple principle, the minimization of vacuum energy. Implementing some additional discrete symmetry assumptions one also obtains predictions for fermion masses, as well as a Higgs mass prediction of 154 GeV.

Dynamical Masses of Young Star Clusters: Constraints on the Stellar IMF and Star-Formation Efficiency
Creators: name: Bastian, N.
name: Goodwin, S. P.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Many recent works have attempted to constrain the stellar initial mass function (IMF) inside massive clusters by comparing their dynamical mass estimates to the measured light. These studies have come to different conclusions, with some claiming standard Kroupa-type IMFs, while others have claimed extreme non-standard IMFs. However, the results appear to be correlated with the age of the clusters, as older clusters (>80 Myr) all appear to be well fit by a Kroupa-type IMF whereas younger clusters display significant scatter in their best fitting IMF. Here we show that this is likely due to the fact that young clusters are out of virial equilibrium and therefore cannot be used for such studies. Hence only the older clusters are suitable for IMF studies. Using only these clusters we find that the IMF does not vary significantly. The youngest clusters can be used instead to constrain the star-formation efficiency (SFE) within clusters. We find that the SFE varies between 20 and 60% and we conclude that approximately 60% of young clusters are unbound and will not survive for more than a few 10's of Myr (i.e. "infant mortality").
