description: In default reasoning, usually not all possible ways of resolving conflicts between default rules are acceptable. Criteria expressing acceptable ways of resolving the conflicts may be hardwired in the inference mechanism, for example specificity in inheritance reasoning can be handled this way, or they may be given abstractly as an ordering on the default rules. In this article we investigate formalizations of the latter approach in Reiter's default logic. Our goal is to analyze and compare the computational properties of three such formalizations in terms of their computational complexity: the prioritized default logics of Baader and Hollunder, and Brewka, and a prioritized default logic that is based on lexicographic comparison. The analysis locates the propositional variants of these logics on the second and third levels of the polynomial hierarchy, and identifies the boundary between tractable and intractable inference for restricted classes of prioritized default theories.

description: Topological pressures of the preimages of $ε$-stable sets and some certain closed subsets of stable sets in positive entropy systems are investigated. It is showed that the topological pressure of any topological system can be calculated in terms of the topological pressure of the preimages of $ε$-stable sets. For the constructed closed subset of the stable set or the unstable set of any point in a measure-theoretic `rather big' set of a topological system with positive entropy, especially for the weakly mixing subset contained in the closure of stable set and unstable set, it is proved that topological pressures of these subsets can be no less than the measure-theoretic pressure.
Romani Peoples’ Resistance to Mainstream Schooling: A Focus on Romani Woman and Girls’ Education and the Educational Policies, Barriers, and Practices in Greece
Creators: name: Macris, Vicki
Publisher: name: Alberta Journal of Educational Research
Year: 2016

description: The Romani (or Roma) people are, perhaps, the oldest and most discriminated against ethnic minority group in Eastern Europe. In particular, Romani women and girls have been described by the UN Women, United Nations Development Program (UNDP), and Office of High Commission of Human Rights (OHCHR) as “one of the most disempowered groups in Europe.” This paper provides an exploratory investigation of Romani women’s and girls’ lack of educational attainment as it looks at some of policy barriers, practices and the nature of Roma peoples’ reluctance to participate in mainstream public schooling in Greek society. There is an urgent need for effective and focused policies that take into account social inclusion, equality, and non-discrimination of Romani women and girls. However, Romani women are ultimately silenced by the continued lack of quantitative and qualitative data, research and statistics, making them Europe’s most invisible minority. De tous les groupes minoritaires de l’Europe orientale, les Roms sont peut-être le peuple le plus exposé aux discriminations. L’ONU Femmes, le Programme des Nations unies pour le développement et le Haut-Commissariat des Nations Unies aux droits de l'homme ont notamment décrit les femmes et les filles roms comme « l’un des groupes les moins émancipés de l’Europe ». Cet article présente une étude exploratoire du faible niveau de scolarité des femmes et des filles roms en évoquant quelques obstacles sur le plan politique, certaines pratiques et la nature de la réticence de la part des Roms à s’intégrer dans le système éducatif public en Grèce. Il existe un besoin urgent pour des politiques efficaces, bien ciblées et qui tiennent compte de l’inclusion sociale, l’égalité et la non-discrimination envers les femmes et les filles roms. Pourtant et ultimement, les femmes roms sont réduites au silence par l’absence continue de données quantitatives et qualitatives, de recherche et de statistiques, ce qui fait d’elles la minorité européenne la moins visible.

description: This thesis presents measurements of electrons at midrapidity from the decays of heavy quarks produced in d+Au collisions at RHIC. A significant enhancement of these electrons is seen at a transverse momentum below 5 GeV/c, indicating strong CNM effects on charm quarks that are not present for lighter quarks. We also report the Rπ0γ, the effect of the converter on the photonic electron yield from neutral pion decays.
International Policy and Roma Education in Europe: Essential Inputs or Centralized Distractions?
Creators: name: Ram, Melanie H.
Publisher: name: Alberta Journal of Educational Research
Year: 2016

description: This article examines the case of Roma inclusion in education as a study of the ways in which international policy can and cannot bring change at the local level. I first reflect on the numerous international organizations and initiatives to improve the educational outcomes of Roma, and to reduce segregation and other non-inclusionary practices. Given these actions—and their relatively small impact—I identify both benefits and drawbacks of international efforts to achieve Roma inclusion and improve education outcomes. I conclude that international organizations provide significant inputs for Roma inclusion, but also serve as centralized distractions that foster extremely high expectations and thus great disappointment with the results. Cet article examine le cas de l’inclusion des Roms dans le système éducatif comme moyen d’évaluer la mesure dans laquelle la politique internationale peut effectuer des changements à l’échelle locale. Ma réflexion porte d’abord sur les nombreux organismes internationaux et les multiples initiatives qui visent l’amélioration de l’éducation aux Roms, et la réduction de la ségrégation et autres pratiques non-inclusives. Compte tenu de ces démarches—et de leur impact relativement petit—j’identifie tant les bienfaits que les désavantages des efforts internationaux qui essaient d’augmenter l’inclusion des Roms et améliorer leur éducation. Je conclus que les organismes internationaux contribuent de façon considérable à l’inclusion des Roms, mais qu’ils servent également de distractions centralisées qui favorisent des attentes extrêmement élevées et ainsi, une grande déception quant aux résultats.

description: Εισαγωγή: Η πανδημία COVID-19 διαταράσσει τη ρουτίνα των ανθρώπων και ως εκ τούτου προκαλεί άγχος και φόβο. Από την άλλη πλευρά, συχνά σημειώνεται ότι οι άνθρωποι φοβούνται μήπως μολυνθούν από τον COVID-19. Μια ομάδα ασθενών που έχουν αυξημένο κίνδυνο ανάπτυξης υπερβολικού φόβου έναντι της COVID-19 είναι οι ασθενείς με άσθμα. Σκοπός: Η παρούσα μεταπτυχιακή εργασία είχε σκοπό να εξετάσει την εγκυρότητα και την αξιοπιστία των μετρήσεων του ερωτηματολογίου Fear of COVID-19 (FCV-19S) για τη μέτρηση του φόβου για την COVID-19 σε έλληνες ενήλικες ασθενείς με άσθμα. Μέθοδος: Πραγματοποιήθηκε έρευνα σε 35 ασθενείς με άσθμα από τα εξωτερικά ιατρεία της Πνευμονολογικής Κλινικής του Νοσοκομείου «Οι Άγιοι Ανάργυροι». Εξετάστηκε η δομική εγκυρότητα, η εγκυρότητα κριτηρίου και η αξιοπιστία (εσωτερική συνοχή) των μετρήσεων της κλίμακας Fear of COVID-19 (FCV-19S). Αποτελέσματα: Η διερευνητική ανάλυση παραγόντων έδειξε ότι οι επτά ερωτήσεις της κλίμακας FCV-19S ομαδοποιούνται σε δύο παράγοντες, που αξιολογούν αντίστοιχα το «Σωματικό φόβο για την Covid-19» και το «Συναισθηματικό φόβο για την Covid-19». Οι δύο παράγοντες βρέθηκε να ερμηνεύουν ένα πολύ μεγάλο ποσοστό της μεταβλητότητας των δεδομένων (74.3%). Τα αποτελέσματα έδειξαν ότι ο πρώτος (α=0.86) και ο δεύτερος (α=0.83) παράγοντας εμφανίζουν πολύ υψηλό επίπεδο αξιοπιστίας. Η κλίμακα FCV-19S εμφάνισε σημαντική συσχέτιση με την κλίμακα δύσπνοιας Borg (r = 0.34, p<0.01) αλλά δεν εμφάνισε σημαντικές συσχετίσεις με το FEV1%, την κλίμακα για την αυτο-αποτελεσματικότητα GSE, το ερωτηματολόγιο για το άγχος STAI, το ερωτηματολόγιο NQ για τον υπεραερισμό και το ερωτηματολόγιο ACT για τον έλεγχο του άσθματος. Συμπεράσματα: Η έρευνα έδωσε ενδείξεις εγκυρότητας και αξιοπιστίας των μετρήσεων της κλίμακας FCV-19S για την αξιολόγηση του φόβου των ασθενών με άσθμα έναντι της Covid-19.

Year: 2016

description: This paper addresses the topic of the inclusion of Roma children in education in Europe through an examination of theory and practice in relation to the issues of Otherness and foreignness. Roma children entering school encounter a vastly different world from their home culture, with different expectations for teaching and learning, for relationships among learners, and with teachers. We address the question of whether the knowledge of these contradictions or discontinuities and knowledge of the ways in which any child from a minority group learns, is sufficient to address the issue of foreignness in educational contexts. The paper highlights the potential for interculturalism and intercultural pedagogies for engaging children from diverse cultures. Cet article porte sur la question de l’inclusion des enfants roms dans le système éducatif en Europe et ce, par un examen de la théorie et la pratique par rapport aux questions de l’altérité et l’extranéité. Les enfants roms qui rentrent à l’école sont confrontés à un monde bien différent de celui de leur propre culture, où les attentes face à l’enseignement et l’apprentissage ne sont pas les mêmes que celles qu’ils connaissent, ni les rapports des apprenants entre eux et entre les apprenants et les enseignants. Nous nous demandons si la conscience de ces contradictions ou discontinuités et la connaissance des façons dont apprennent les enfants de groupes minoritaires suffisent pour aborder la question de l’extranéité dans des milieux éducatifs. L’article souligne le potentiel de l’interculturalisme et des pédagogies interculturelles pour stimuler la participation des enfants de diverses cultures.

ASSESSMENT OF CHALLENGES OF ELECTRONIC BANKING  (E-BANKING) IN ETHIOPIAN BANK SECTOR–CASE STUDY  OF SOUTH ETHIOPIA DISTRICT
Creators: name: Tesfalem Mengiste
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The  advent  of   current   technology  such   as    internet  use  is  developing  fast  and  is
constantly bringing new magnitudes to our daily life. The banking industry is one of the
sectors that has benefited from the evolving technology by the introduction of Electronic
banking (E-banking) systems which provide easy access to banking services.   This study
was  carried  out  to  assess  the  prospect  and  challenges  of  E-  banking  in  Ethiopian
sector,  in  southern Ethiopia district.  The  study  also  identified  the  main  E-banking
products  of  the  bank  namely:  Automated  Teller Machine  (ATM),  mobile  and  Internet
(online)  banking,  electronic  funds  transfer,  direct  bill  payments  and  credit  card.
Most respondents  (44.40%) prefer ATM relative to other E-banking products, however,
most  customers  also  uses  combination of  the  products.  The  study identified  benefits
customers derive  from E banking as saving of  time, quickness  in banking transactions,
easy access to account details and reduction of long queues in banking halls. According
to  the  study,  customer satisfaction  and  competition  from  other  banks  were  the  main
influencing  factors  for E-banking adoption. Notwithstanding E-banking advantages, it is
confronted  with  challenges  such  as  frequent  network  failure,  high  bank  charges, limited  amount  of  cash withdrawal  and wrong debit was  identified  as  the  paramount
challenges. Nevertheless,     the researcher     recommended     that     for     effective    E-
banking   system, customer  education and marketing  of E-banking  products  should  be
the key strategy to use and to attract more customers, increasing security for E-banking
products, reduction of charges of E-banking products and increasing more ATM outlets
in the country.
Squeaky Wheel Optimization

description: We describe a general approach to optimization which we term `Squeaky Wheel' Optimization (SWO). In SWO, a greedy algorithm is used to construct a solution which is then analyzed to find the trouble spots, i.e., those elements, that, if improved, are likely to improve the objective function score. The results of the analysis are used to generate new priorities that determine the order in which the greedy algorithm constructs the next solution. This Construct/Analyze/Prioritize cycle continues until some limit is reached, or an acceptable solution is found. SWO can be viewed as operating on two search spaces: solutions and prioritizations. Successive solutions are only indirectly related, via the re-prioritization that results from analyzing the prior solution. Similarly, successive prioritizations are generated by constructing and analyzing solutions. This `coupled search' has some interesting properties, which we discuss. We report encouraging experimental results on two domains, scheduling problems that arise in fiber-optic cable manufacturing, and graph coloring problems. The fact that these domains are very different supports our claim that SWO is a general technique for optimization.

Year: 2016

description: The paper gives an overview of Roma, Gypsy and Traveller (RGT) educational exclusion in the European Union and seeks to provide insights into good practice through case studies focusing on Bulgaria and the UK. The paper makes a case for the promotion of collaborative relationships, where RGT communities are active partners in developing curricula and decision-making in school. It is argued in the paper that such action needs to be made in tandem with interventionist and redistributive policy frameworks at the national and European level. Cet article offre un aperçu général de l’exclusion éducative pour les Roms, les Tsiganes et les gens du voyage (RTG) dans l’union européenne et cherche à éclairer les meilleures pratiques en se penchant sur des études de cas portant sur la Bulgarie et le Royaume-Uni. Cet article fait la promotion de relations de collaboration au sein desquels les communautés RTG constituent des partenaires actifs dans le développement des programmes d’études et des prises de décisions à l’école. L’article fait valoir qu’une telle démarche doit être accompagnée de cadres de politiques interventionnistes et redistributives aux échelles nationales et européennes.

Development of organic pi-conjugated materials : bonding and structural morphology
Creators: name: Thompson, Kyle
Publisher: name: University of British Columbia
Year: 2019

description: Organic semiconductors, which commonly contain π-conjugated systems, have many advantages over inorganic semiconductors. These advantages have generated significant research interest and have allowed for their successful use in a variety of electronic and optoelectronic devices, such as organic light emitting diodes. Herein, we demonstrate a novel method for the synthesis of nitrogen-containing π-conjugated luminescent materials. The typical synthetic methods suffer from disadvantages such as harsh reaction conditions, expensive metal catalysts, and stoichiometric reagents. By using hydroamination, an atom-economic catalytic route to amine-containing compounds, we demonstrate an alternative synthetic method which circumvents these limitations. We also demonstrate a novel synthetic route to polymeric organic semiconducting materials with a fiber-like morphology. Many of the existing methods suffer from the limitation of requiring very specific conditions and monomers. Employing the grafting-from method of bottlebrush synthesis, RAFT and SET-LRP polymerization techniques are used to produce long fiber-like nanowires from arbitrary semiconducting monomers. These cylindrical nanofibers can be applied to a diverse range of organic semiconductors, with potential applications in macroscale optoelectronic devices or as functional nanoscale objects.

description: In the machine learning problem of multi-label classification, the objective is to determine for each test instance which classes the instance belongs to. In this work, we consider multi-label classification in the context of multi-label radioisotope classification for gamma spectra data. By viewing spectra as discrete distributions we tackle a more challenging variant of multi-label classification where the goal is to ascribe a proportion to each class label, not just a binary variable. Motivated by this application to radioisotope identification, we aim to simultaneously predict label proportions while also performing out-of-distribution (OOD) detection. To achieve this goal, we introduce a novel semi-supervised loss function that combines a traditional supervised loss with an unsupervised reconstruction error penalty. This work demonstrates that the proposed model can successfully perform radioisotope identification in a realistic test scenario. We also show how to extend this approach to perform OOD detection which can determine when the model prediction should not be trusted due to the presence of an anomalous source. The semi-supervised model, trained on gamma spectra based on a measurement of a real fission source containing a mixture of 30 distinct radioisotopes (labeled by a spectroscopist), learned to estimate in-distribution (ID) samples with about 39% error while simultaneously being able to differentiate (with 95% confidence) between ID and OOD samples with an anomaly contribution as small as 10%.

description: The expansion and collision of two wind-blown superbubbles is investigated numerically. Our models go beyond previous simulations of molecular cloud formation from converging gas flows by exploring this process with realistic flow parameters, sizes and timescales. The superbubbles are blown by time-dependent winds and supernova explosions, calculated from population synthesis models. They expand into a uniform or turbulent diffuse medium. We find that dense, cold gas clumps and filaments form naturally in the compressed collision zone of the two superbubbles. Their shapes resemble the elongated, irregular structure of observed cold, molecular gas filaments and clumps. At the end of the simulations, between 65 and 80 percent of the total gas mass in our simulation box is contained in these structures. The clumps are found in a variety of physical states, ranging from pressure equilibrium with the surrounding medium to highly under-pressured clumps with large irregular internal motions and structures which are rotationally supported.

description: We report on the observation of high-T_c superconductivity (SC) emerging with the background of an antiferromagnetic (AFM) order in the five-layered cuprate Ba_2Ca_4Cu_5O_10(F,O)_2 through 19F-NMR and zero-field Cu-NMR studies. The measurements of spectrum and nuclear spin-lattice relaxation rates 19(1/T_1) of 19F-NMR give convincing evidence for the AFM order taking place below T_N = 175 K and for the onset of SC below T_c = 52 K, hence both coexisting. The zero-field Cu-NMR study has revealed that AFM moments at Cu sites are 0.14 mu_B at outer CuO_2 layers and 0.20 mu_B at inner ones. We remark that an intimate coupling exists between the AFM state and the SC order parameter below T_c = 52 K; the spin alignment in the AFM state is presumably changed in the SC-AFM mixed state.

THE IMPACT OF HOUSE SCREENING INTERVENTION ON EXPOSURE TO VECTORS AND ON MALARIA TRANSMISSION, AND THE SUSCEPTIBILITY STATUS OF ANOPHELES ARABIENSIS TO INSECTICIDES IN ARBAMINCH TOWN, SOUTHWESTERN ETHIOPIA: A RANDOMIZED TRIAL
Creators: name: SOLOMON KINDE GETAWEN

Year: 2016

description: House is the major site for malaria infection where most human-vector contact takes places.
Hence, screening of houses might reduce the risk of malaria infection by limiting house entry of
vectors. This study was assessed the impact of screening doors and windows on indoor density,
sporozoite and entomological inoculation rate (EIR) of malaria vectors in malaria hotspot
Kebeles (smallest administrative unit in Ethiopia) of Arba Minch town, southwest Ethiopia. The
insecticide susceptibility status of Anopheles arabiensis was assessed. Pre-intervention mosquito
collection was made by Center for Disease Control and Prevention (CDC) light traps from 92
randomly selected houses. The 92 households were randomized into control and intervention
groups. The doors and windows of 46 houses were screened by wire-mesh. Post-intervention
mosquito sampling was done by CDC light traps in intervention and control houses. Anophelesmosquitoes were identified into species using a morphological key, and then the circum-
sporozoite proteins (CSPs) analysis was conducted using Enzyme-Linked Immuno-Sorbent
Assay (ELISA). All the household members both in the intervention and control groups were
screened for malaria parasite using a rapid diagnostic test. Anopheles larvae and pupae were
collected from natural breeding habitats within the Kebeles, and 2-3 days old female An.
arabiensis was tested for susceptibility to insecticide. Probit analysis was employed to calculate
the knock down time of An. arabiensis. A Generalized Estimating Equations with a negative
binomial distribution was used to see the impact of screening intervention by account for over
dispersion of An. arabiensis counts and repeated catches made in the same house. There was a
48% reduction in indoor density of An. arabiensis and it was statistically significant (p = 0.001).
The impact of house screening intervention was substantially high (69%) on unfed (active host-seeking) An. arabiensis than other abdominal stages. Plasmodium falciparum CSP rate was 1.6%
in houses screened with wire-mesh and 2.7 % in control houses. Screening doors and windows
reduced the sporozoite rate of An. arabiensis by 41%, but the reduction was not statistically
significant (p>0.05). Screening doors and windows reduced the infectious bites of An. arabiensis
by 70%, and the risk of receiving infectious bites was 3.3 times higher in control houses
compared to the screened houses. House screening may not affect bed net use rate. Anopheles
arabiensis has developed resistance to deltamethrin but was highly susceptible to bendiocarb,
propoxur, and malathion. Finally, house screening intervention has played a substantial role byreducing the exposure to malaria vectors, and hence can be recommended as an important
intervention to include in malaria vector control package.

description: Intractable distributions present a common difficulty in inference within the probabilistic knowledge representation framework and variational methods have recently been popular in providing an approximate solution. In this article, we describe a perturbational approach in the form of a cumulant expansion which, to lowest order, recovers the standard Kullback-Leibler variational bound. Higher-order terms describe corrections on the variational approach without incurring much further computational cost. The relationship to other perturbational approaches such as TAP is also elucidated. We demonstrate the method on a particular class of undirected graphical models, Boltzmann machines, for which our simulation results confirm improved accuracy and enhanced stability during learning.

description: It is well-known that the finite-gap solutions of the KdV equation can be generated by its recursion operator.We generalize the result to a special form of Lax pair, from which a method to constrain the integrable system to a lower-dimensional or fewer variable integrable system is proposed. A direct result is that the $n$-soliton solutions of the KdV hierarchy can be completely depicted by a series of ordinary differential equations (ODEs), which may be gotten by a simple but unfamiliar Lax pair. Furthermore the AKNS hierarchy is constrained to a series of univariate integrable hierarchies. The key is a special form of Lax pair for the AKNS hierarchy. It is proved that under the constraints all equations of the AKNS hierarchy are linearizable.

description: The emergence of spin-orbit torques as a promising approach to energy-efficient magnetic switching has generated large interest in material systems with easily and fully tunable spin-orbit torques. Here, current-induced spin-orbit torques in VO$_2$/NiFe heterostructures were investigated using spin-torque ferromagnetic resonance, where the VO$_2$ layer undergoes a prominent insulator-metal transition. A roughly two-fold increase in the Gilbert damping parameter, $α$, with temperature was attributed to the change in the VO$_2$/NiFe interface spin absorption across the VO$_2$ phase transition. More remarkably, a large modulation ($\pm$100%) and a sign change of the current-induced spin-orbit torque across the VO$_2$ phase transition suggest two competing spin-orbit torque generating mechanisms. The bulk spin Hall effect in metallic VO$_2$, corroborated by our first-principles calculation of spin Hall conductivity, $σ_{SH} \approx 10^4 \frac{\hbar}{e} Ω^{-1} m^{-1}$, is verified as the main source of the spin-orbit torque in the metallic phase. The self-induced/anomalous torque in NiFe, of the opposite sign and a similar magnitude to the bulk spin Hall effect in metallic VO$_2$, could be the other competing mechanism that dominates as temperature decreases. For applications, the strong tunability of the torque strength and direction opens a new route to tailor spin-orbit torques of materials which undergo phase transitions for new device functionalities.

Chromium isotopes, iron speciation, and the evolution of Earth's surface chemistry through time
Creators: name: Bauer, Kohen Witt
Publisher: name: University of British Columbia

description: The oxygen concentration of the ocean atmosphere system regulates the nature, activity and diversity of life on Earth. Atmospheric and ocean oxygenation is tightly coupled to the global biogeochemical cycles of C, N, P, S and Fe, as well as climate. Reconstructing the history of oxygen on planet Earth, therefore, is a key component to understanding the evolution of life. Our emergent picture of the evolution of Earth’s surface redox state with its links to the evolution of life and climate relies heavily on interpretations of geochemical information preserved in the rock record. The Cr isotope and Fe-speciation proxies are two widely applied tools used to diagnose redox conditions in both modern and ancient depositional environments. Many aspects of the precise mechanisms that lend the use of these two transition metals as paleoredox proxies, however, remain unclear, confounding accurate reconstructions of paleo-oxygen concentrations that rely on Cr isotope and Fe-speciation data. In this work I studied Cr isotope and Fe speciation proxy systematics to develop more nuanced frameworks for how these two paleoredox proxies may be employed to reconstruct depositional redox states in both modern and past environments. I determined the Cr isotope and Fe mineral composition of modern marine hydrothermal sediments, revealing Cr isotope fractionations that imply deposition from an oxygenated deep ocean. I determined Cr isotope fractionations associated with the reduction of Cr(VI) in modern ferruginous sediments, revealing that the magnitude of Cr isotope fractionation in such environments is linked to the speciation of Fe and the oxygen penetration depth of the sediments. I determined Fe-speciation and trace metal abundances of sediments deposited during oceanic anoxic event 1a (OAE1a), revealing that during this interval the oceans were anoxic and Fe-rich (ferruginous) for more than 1 million years. Lastly, I determined the Fe-speciation of suspended and sedimented material from two modern ferruginous lakes, revealing that the mineral magnetite forms authigenically in the ferruginous water columns. This new knowledge of Cr and Fe proxy systematics will allow for more refined interpretations of paleo oxygen concentrations based on Cr isotope and Fe-speciation signals captured in the rock record through time.

description: We present deep J and Ks band photometry of 20 high redshift galaxy clusters between z=0.8-1.5, 19 of which are observed with the MOIRCS instrument on the Subaru Telescope. By using near-infrared light as a proxy for stellar mass we find the surprising result that the average stellar mass of Brightest Cluster Galaxies (BCGs) has remained constant at ~9e11MSol since z~1.5. We investigate the effect on this result of differing star formation histories generated by three well known and independent stellar population codes and find it to be robust for reasonable, physically motivated choices of age and metallicity. By performing Monte Carlo simulations we find that the result is unaffected by any correlation between BCG mass and cluster mass in either the observed or model clusters. The large stellar masses imply that the assemblage of these galaxies took place at the same time as the initial burst of star formation. This result leads us to conclude that dry merging has had little effect on the average stellar mass of BCGs over the last 9-10 Gyr in stark contrast to the predictions of semi-analytic models, based on the hierarchical merging of dark matter haloes, which predict a more protracted mass build up over a Hubble time. We discuss however that there is potential for reconciliation between observation and theory if there is a significant growth of material in the intracluster light over the same period.
