description: We analyze correlations in step-edge fluctuations using the Bortz-Kalos-Lebowitz kinetic Monte Carlo algorithm, with a 2-parameter expression for energy barriers, and compare with our VT-STM line-scan experiments on spiral steps on Pb(111). The scaling of the correlation times gives a dynamic exponent confirming the expected step-edge-diffusion rate-limiting kinetics both in the MC and in the experiments. We both calculate and measure the temperature dependence of (mass) transport properties via the characteristic hopping times and deduce therefrom the notoriously-elusive effective energy barrier for the edge fluctuations. With a careful analysis we point out the necessity of a more complex model to mimic the kinetics of a Pb(111) surface for certain parameter ranges.

Hafnium complexes stabilized by a macrocyclic ligand
Creators: name: Corkin, James R.
Publisher: name: University of British Columbia
Year: 2009

description: The goal of this thesis is to investigate the chemistry of hafnium complexes of the macrocyclic ligand, PhP(CH2SiMe2NSiMe2CH2)2PPh ([P2N2]). The hafnium dichloride, [P2N2]HfCl2 (1) is used as a starting material for all other compounds synthesized. 1 is isostructural with its zirconium analogue, [P2N2]ZrCl2 , but does not exhibit identical chemistry. While reaction of [P2N2]ZrCl2 with 2 equivalents of C8K under N2 resulted in formation of a zirconium dinitrogen compound, the same is not true for the hafnium analogue. Instead, the major product of the reaction of 1 with 2 equivalents of C8K is a hafnium dimer, {[P2N2]Hf}2 (2). [P2N2]HfI2 (3) is synthesized via the reaction of 1 with excess trimethylsilyliodide. Evidence will be presented that ([P2N2]Hf)2(μ-η2:η2-N2) (4) is the major product of the reaction between 3 and 2 equivalents of C8K under dinitrogen, while {[P2N2]Hf}2 (2) and [P2N2]Hf(C7H8) (5) appear to be minor products. Reaction of 1 with 2 equivalents of MeMgCl results in the formation of [P2N2]HfMe2 (6). The zirconium analogue of 6 reacts with toluene under an atmosphere of H2 to give [P2N2]Zr(C7H8), but this is not true for 6. Instead, reaction of 6 under H2 results in the formation of a hafnium tetrahydride, {[P2N2]Hf}2(μ-H)4 (7). A metathesis reaction of one equivalent of 1 with one equivalent of Mg(C4H6)(THF)2 results in formation of [P2N2]Hf(C4H6) (8). Unlike most mononuclear [P2N2] compounds, this compound exhibits 2 inequivalent phosphorus atoms evidenced by an AB doublet pattern in the 31P{1H} NMR spectrum.

description: As dairy farms grow and specialize in milking cows, one enterprise that may be removed from the dairy farm to allow for milk cow herd expansion is heifer raising. Custom heifer raising is increasingly common across the country and purchasing heifers may be preferred to raising heifers. However, these alternatives are not suitable for all dairy farmers. In this article, we examine heifer enterprise costs relative to using a custom raiser or purchasing heifers. We identify factors that should be considered in making the proper decision relative to the heifer enterprise.

description: The structure of the solar corona is dominated by the magnetic field because the magnetic pressure is about four orders of magnitude higher than the plasma pressure. Due to the high conductivity the emitting coronal plasma (visible e.g. in SOHO/EIT) outlines the magnetic field lines. The gradient of the emitting plasma structures is significantly lower parallel to the magnetic field lines than in the perpendicular direction. Consequently information regarding the coronal magnetic field can be used for the interpretation of coronal plasma structures. We extrapolate the coronal magnetic field from photospheric magnetic field measurements into the corona. The extrapolation method depends on assumptions regarding coronal currents, e.g. potential fields (current free) or force-free fields (current parallel to magnetic field). As a next step we project the reconstructed 3D magnetic field lines on an EIT-image and compare with the emitting plasma structures. Coronal loops are identified as closed magnetic field lines with a high emissivity in EIT and a small gradient of the emissivity along the magnetic field.

description: Social capital in the past two decades has emerged as a dominant paradigm in the various social science disciplines. However, its adoption by the different social science disciplines has led to multiple and often conflicting definitions of social capital. Some differences in the definition of social capital can be explained because scientists have included in the definition expressions of its possible uses, where it resides, and how its service capacity can be changed. This paper defends the social capital metaphor by pointing out that social capital has many important capital-like properties including service potential, durability, flexibility, substitutability, opportunities for decay (maintenance), reliability, ability to create other capital forms, and investment (disinvestment) opportunities. Social capital is compared to other forms of capital including cultural capital and human capital.

description: Microscopy observations show that suspensions of synthetic and natural nano-layered smectite clay particles submitted to a strong external electric field undergo a fast and extended structuring. This structuring results from the interaction between induced electric dipoles, and is only possible for particles with suitable polarization properties. Smectite clay colloids are observed to be particularly suitable, in contrast to similar suspensions of a non-swelling clay. Synchrotron X-ray scattering experiments provide the orientation distributions for the particles. These distributions are understood in terms of competing (i) homogenizing entropy and (ii) interaction between the particles and the local electric field; they show that clay particles polarize along their silica sheet. Furthermore, a change in the platelet separation inside nano-layered particles occurs under application of the electric field, indicating that intercalated ions and water molecules play a role in their electric polarization. The resulting induced dipole is structurally attached to the particle, and this causes particles to reorient and interact, resulting in the observed macroscopic structuring. The macroscopic properties of these electro-rheological smectite suspensions may be tuned by controlling the nature and quantity of the intercalated species, at the nanoscale.

description: Understanding clients' wants and needs is vital to the sustained success of any service business, and veterinary medicine offers no exception. The Veterinary Teaching Hospital (VTH) at the Michigan State University College of Veterinary Medicine (MSU-CVM) has successfully maintained a position at the forefront of the veterinary profession throughout most of its history. The staff has consistently been composed of clinicians who have been chosen because of their excellence and expertise. However, the assumption that emphasis on clinical excellence will, by itself, provide the foundation for sustained success in the client flow and business at the hospital has been unchallenged to date. In order to provide the best possible customer service, our clients' likes, dislikes, wants, and needs must be fully characterized and quantified. To assess client satisfaction with the VTH, a study was designed whose objective was to identify the areas in the VTH that are most valued and highly regarded versus those that need improvement in order to sustain the current success of the small animal hospital. The results of this study can be used as an outline for the development of a plan to maintain and improve customer satisfaction and, ultimately, to sustain the teaching caseload and business of the hospital. In addition, this endeavor will serve to set a good example for our students by modeling the best management practices and establishing a critical blend of quality medicine/surgery and customer service.

description: Away from equilibrium, the properties of open quantum systems depend on the details of their environment. A microscopic derivation of a master equation (ME) is therefore crucial. Of particular interest are Lindblad-type equations, not only because they provide the most general class of Markovian MEs, but also since they are the starting point for efficient quantum trajectory simulations. Lindblad-type MEs are commonly derived from the Born-Markov-Redfield equation via a rotating-wave approximation (RWA). However the RWA is valid only for ultra-weak system bath coupling and often fails to accurately describe nonequilibrium processes. Here we derive an alternative Lindbladian approximation to the Redfield equation, which does not rely on ultra-weak system-bath coupling. Applying it to an extended Hubbard model coupled to Ohmic baths, we show that, especially away from equilibrium, it provides a good approximation in large parameter regimes where the RWA fails.

description: We consider the Kuramoto-Sivashinsky (KS) equation in one spatial dimension with periodic boundary conditions. We apply a Lyapunov function argument similar to the one first introduced by Nicolaenko, Scheurer, and Temam, and later improved by Collet, Eckmann, Epstein and Stubbe, and Goodman, to prove that ||u||_2 < C L^1.5. This result is slightly weaker than that recently announced by Giacomelli and Otto, but applies in the presence of an additional linear destabilizing term. We further show that for a large class of Lyapunov functions ϕthe exponent 1.5 is the best possible from this line of argument. Further, this result together with a result of Molinet gives an improved estimate for L_2 boundedness of the Kuramoto-Sivashinsky equation in thin rectangular domains in two spatial dimensions.

description: This work uses unique data from three dairy dependent communities in rural Wisconsin to test established theory and empirical studies that link farm structure to local purchasing patterns and community economic development. A theoretical model of purchasing choices is developed to derive the determinants of local purchasing by dairy farms. This model is tested empirically using a double bounded Tobit model. The empirical estimations find little support for any linkage between farm size and local purchasing patterns across eleven major dairy farm inputs. The results do suggest that different community business characteristics (the supply side) and community attachment provide some explanations for diverse purchasing patterns.

description: A baroclinic model for the atmospheric jet at middle-latitudes is used as a stochastic generator of time series of the total energy of the system. Statistical inference of extreme values is applied to yearly maxima sequences of the time series, in the rigorous setting provided by extreme value theory. In particular, the Generalized Extreme Value (GEV) family of distributions is used here. Several physically realistic values of the parameter $T_E$, descriptive of the forced equator-to-pole temperature gradient and responsible for setting the average baroclinicity in the atmospheric model, are examined. The location and scale GEV parameters are found to have a piecewise smooth, monotonically increasing dependence on $T_E$. This is in agreement with the similar dependence on $T_E$ observed in the same system when other dynamically and physically relevant observables are considered. The GEV shape parameter also increases with $T_E$ but is always negative, as \textit{a priori} required by the boundedness of the total energy of the system. The sensitivity of the statistical inference process is studied with respect to the selection procedure of the maxima: the roles of both the length of maxima sequences and of the length of data blocks over which the maxima are computed are critically analyzed. Issues related to model sensitivity are also explored by varying the resolution of the system.

description: This study focuses on the impacts state shared revenues has on local government finances. Specifically we examine what is referred to in the academic literature as the "flypaper effect." Using a simple model of local fiscal behavior Bradford and Oates (1971a, 1971b) predict that aids to local governments is the equivalent to cash transfers to local constituents. Thus aids to local governments should have the same impact on local government spending as does increases in local personal income. Empirical studies, however, have found that aids to local governments has a much greater simulative affect on local spending than does a comparable increase in the income of local constituents. Private income is disproportionately spend on private consumption while aids, income received by local governments, is primarily spent on public services.

Moreover, we introduce a graded persistence probability that a site does not flip more than n times and demonstrate how local persistence can be studied in seed simulations. Finally, the problem of spatial (as opposed to temporal) persistence is investigated.

International Trade and the Natural Resource 'Curse' in Southeast Asia: Does China's Growth Threaten Regional Development

Subjects: International Relations/Trade

description: China's growth, along with its increasing integration with world markets through WTO accession, abolition of Multifiber Arrangement (MFA) quotas, and reduced trade barriers with ASEAN, is expected to have significant effects on the structure of regional production and trade. Through bilateral trade growth as well as through competition with China in global markets, Southeast Asia's resource-abundant economies will become more intensive in natural resource-based exports and much less so in low-end, labor-intensive manufacturing such as garments. Both these effects will tend to increase demand for natural resources, one through a direct product market effect, the other by driving down the price of a complementary input, low-skill labor. A question that then arises is how these trends will interact with the other major phenomenon currently sweeping through Southeast Asia, namely decentralization. With reduced national government power and little or no accountability at the local level, the potential for disastrous rates of resource exploitation is high. If sufficiently severe, the combination of increased demand for natural resources and diminished constraints on their could expose the region to reduced rates of economic growth, a variant of the "natural resource curse" argument, which maintains that resource-abundant economies grow more slowly than others.

description: Abandoning the perfect fluid hypothesis, we investigate here the possibility that the dark energy equation of state (EoS) $w$ is a nonlinear function of the energy density $ρ$. To this aim, we consider four different EoS describing classical fluids near thermodynamical critical points and discuss the main features of cosmological models made out of dust matter and a dark energy term with the given EoS. Each model is tested against the data on the dimensionless coordinate distance to Type Ia Supernovae and radio galaxies, the shift and the acoustic peak parameters and the positions of the first three peaks in the anisotropy spectrum of the comic microwave background radation. We propose a possible interpretation of each model in the framework of scalar field quintessence determining the shape of the self interaction potential $V(ϕ)$ that gives rise to each one of the considered thermodynamical EoS. As a general result, we demonstrate that replacing the perfect fluid EoS with more generar expressions gives both the possibility of successfully solving the problem of cosmic acceleration escaping the resort to phantom models.

description: La ricerca si propone di sondare in maniera completa e approfondita la rappresentazione del banchetto nel testo letterario e, in senso più ampio, nel testo inteso come sistema di segni (siano essi parole, gesti, espressioni facciali, modi di esprimersi, mezzi di comunicazione in genere).
Il banchetto è una ‘messa in scena’ che assume nel testo letterario e nei linguaggi espressivi dell’arte contemporanea diverse funzioni a livello tematico e stilistico. Nel lavoro si analizza ognuna di queste funzioni: la funzione denotativa, connotativa, strutturale, metaforica, metanarrativa e stilistica e comunicativa. 
La linea di analisi tracciata si conclude con un particolare focus sulla rappresentazione del banchetto nel testo letterario e nei media come strumento di comunicazione all’interno di un altro mezzo di comunicazione. Con questa premessa la candidata termina con il capitolo conclusivo dedicando spazio all’immagine del pasto postmoderno. Il banchetto, in quanto rito simbolico, media contenuti legati all’universo culturale, rivela connessioni con la realtà storico-sociale, con l’assetto profondo dell’identità individuale e collettiva, costituendo un polo di aggregazione di diverse dimensioni di umanità. Nonostante l’estrema duttilità alla quale si presta l’immaginario del banchetto sul piano artistico e concettuale, nella quotidianità il momento conviviale continua per l’uomo postmoderno a evocare sentimenti e valori tradizionali ai quali ispirarsi.
description: Aim of the research is to analyze banquet’s representation in the literary texts and, more broadly, in the text meant as system of signs (including words, gestures, facial expressions, behaviors or media).
Banquet is a “scenery” that assumes several stylistic and thematic functions both in the literary text and in the expressions of the contemporary art. Denotative, connotative, structural, metaphoric, metanarrative, stylistic and communicative functions will be here described. 
Analysis proceeds further deeply into a focus on the representation of the banquet as a communication tool within another communicative instrument such as a literary text or a media.
Finally, the last chapter will be dedicated to the representations of the modern meal: the banquet, as a symbolic ritual, is linked to the cultural background, reveals connections with the historical-social context, being a benchmark for different kinds of humanities. Therefore, despite the extreme variations of its artistic and intellectual representations, the banquet still evocates traditional sentiments and virtues for the postmodern man inspiration.

Novel chromium nitrosyl complexes
Creators: name: Jandciu, Eric William
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the synthesis, structure and characteristic reactivity of a series of novel chromium nitrosyl complexes. Many compounds of the form Cr(NO)(N'Pr₂)R₂ can be prepared by treatment of the bis(benzoate) precursor Cr(NO)(N'Pr₂)(0₂CPh) ₂ with the appropriate MgR₂ reagent. The resulting formally unsaturated bis(hydrocarbyl) complexes exhibit interesting features in their solid-state molecular structures. For example, when R = Bz there exists both an agostic hydrogen interaction from the amide ligand as well as an ƞ²-benzyl interaction. In solution, the bis(hydrocarbyl) complexes are fluxional, demonstrating rotation about the chromium-amide bond. Variable temperature ¹H NMR spectroscopy has been employed to study this phenomenon. In one instance, with R = o-tolyl, a different reaction pathway is followed. Instead of the bis(hydrocarbyl) complex, a nitrosyl-cleaved oxo imido compound Cr(0)(N'Pr₂)(NR)R is isolated. The solid-state molecular structure of this compound exhibits a Cr-N(imido)-C bond angle that is more bent than in any other previously prepared metal-imido complex. The reactivity of the bis(hydrocarbyl) complexes has also been explored. The insertion of isocyanides into one of the Cr-C bonds of these species proceeds smoothly, although reactions with carbon monoxide and ethylene are not as straightforward. Experiments with Lewis bases, Bronsted-Lowry acids, water and dioxygen are also complicated, most likely due to the inherent instability of the complexes. In that regard, the thermolysis of the bis(hydrocarbyl) compounds is investigated. β-Hydrogen elimination from the amide ligand is shown to be a favourable reaction pathway, and this is believed to lead to the decomposition of the bis(hydrocarbyl) compounds. In many cases, computational means have also been utilized as a means of gaining insight into the experimental observations.

description: The cavity perturbation technique is an extremely powerful method for measuring the electrodynamic response of a material in the millimeter- and sub-millimeter spectral range (10 GHz to 1 THz), particularly in the case of high-field/frequency magnetic resonance spectroscopy. However, the application of such techniques within the limited space of a high-field magnet presents significant technical challenges. We describe a 7.62 mm x 7.62 mm (diameter x length) rotating cylindrical cavity which overcomes these problems.

description: We examine linkages between national agricultural markets and the pattern of deforestation and agricultural development in an upland watershed. Growth in the watershed has been associated with deforestation as well as increasing evidence of agricultural land quality degradation, soil erosion and diminished watershed function. We ask to what extent forces external to the watershed and the local economy, and in particular market development and associated economic policies, might influence land use and resource management decisions. The evidence indicates that national markets -- and thus policies -- may play a much larger role in determining upland farmers' land allocation decisions than is commonly assumed in the design of upland "sustainable agriculture" projects and policies.
College Readiness among Students who Attended an Enrichment Program

description: Many studies have found that enrichment programs help students to improve academically, socially and personally in terms of college success and matriculation (Bernhardt, 2013; Contreras, 2011; Gullatt & Jan, 2011; Venezia, & Jaeger, 2013). The purpose of this study was to describe the perceptions of academic, social and personal preparedness and adjustment in college of students who did and did not participate in an enrichment program(s) intended to help them succeed in college. A descriptive survey was completed voluntarily online by the enrichment group, and respondents were asked to select a peer in their program of study whom s/he believed did not attend a college preparatory enrichment program to complete the survey also. However, only participants who received enrichment completed the survey and took part in the follow-up interview. Descriptive statistics were used to analyze the findings and the original comparisons intended were not able to be made. All participants rated items using a six point scale to indicate how academically, socially, and personally prepared they felt they were for college, and using a four point scale to indicate how satisfied they were with their college. Participants also had opportunities to state what aspects of their enrichment experience were helpful in college and from those participants a subsample who was interviewed stated that they wanted to remain an active part of the program, suggesting such programs are helpful.

description: Gravitational Wave (GW) events are physical processes that significantly perturbate space-time, e.g. compact binary coalescenses, causing the production of GWs. The detection of GWs by a worldwide network of advanced interferometers offer unique opportunities for multi-messenger searches and electromagnetic counterpart associations. While carrying extremely useful information, searches for associated electromagnetic emission are challenging due to large sky localisation uncertainties provided by the current GW observatories LIGO and Virgo. Here we present the methods and procedures used within the High Energy Stereoscopic System (H.E.S.S.) in searches for very-high-energy (VHE) gamma-ray emission associated to the emission of GWs from extreme events. To do so we create several algorithms dedicated to schedule GW follow-up observations by creating optimized pointing paterns. We describe algorithms using 2-dimensional GW localisation information and algorithms correlating the galaxy distribution in the local universe, by using galaxy catalogs, with the 3-dimensional GW localisation information and evaluate their performances. The H.E.S.S. automatic GW follow-up chain, described in this paper, is optimized to initiate GW follow-up observations within less than 1 minute after the alert reception. These developements allowed H.E.S.S. observations of 6 GW events out of the 67 non-retracted GW events detected during the first three observation runs of LIGO and Virgo reaching VHE $γ$-ray coverages of up to 70% of the GW localisation.

The Effects of Perceived Parental Involvement and Value of Achievement on Student Achievement in Inner-City African American 7th Grade Males
Creators: name: Dempsey, Heather

Year: 2014
Subjects: subject: Education -- Research papers (Graduate)

description: This correlational study examined the relationships between perceptions parental involvement, beliefs about work and achievement, and students’ academic achievement. Previous research indicates that parental involvement in school activities benefits students’ academic success. However, the definition of “parental involvement” varies between ethnic, racial, and socioeconomic groups. Previous research has indicated that one program or type of “involvement” does not have the same effect for all students, and in fact, different populations require different levels and types of involvement to ensure success. The current study used a convenience sample and examined correlations between both students’ and parents’ perceptions of parental involvement, personal achievement values, and students’ actual academic achievement, defined by their GPA’s. No significant correlations were found between parental involvement, personal beliefs about achievement, and GPA. However, significant positive correlations were found between students’ and parents’ ratings of parental involvement and their beliefs about work and achievement, suggesting these perceptions were in accord with one another. While results of the study were inconclusive in determining the effectiveness of values and parental involvement on grades, they did yield some interesting findings and considerations for future research in this area.

Figure 8L
A right maxilla fragment, AMNH 8497, from Clambank Hollow, is referred to Exostinus lancensis (fig. 8L). As the specimen is broken, little can be said of the shape of the maxilla. The teeth are indistinguishable from those of E. lancensis, and are pleurodont with unexpanded bases and slightly recurved crowns. The crowns consist of a principal central cusp with an anterior crest but no distinct anterior cusp. The posterior cusp is not developed. Faint vertical striations are present on the lingual side. The slender teeth project to one-third and one-half of their length above the jaw.

description: We construct new charged solutions of the Einstein-Maxwell field equations with cosmological constant. These solutions describe the nut-charged generalisation of the higher dimensional Reissner-Nordström spacetimes. For a negative cosmological constant these solutions are the charged generalizations of the topological nut-charged black hole solutions in higher dimensions. Finally, we discuss the global structure of such solutions and possible applications.

The Effects of Small Group Phonics Intervention on Low Achieving Kindergarten Students
Creators: name: Dobry, Katherine
Publisher: name: Maryland Shared Open Access Repository
Year: 2014
Subjects: subject: Education -- Research papers (Graduate)

description: The purpose of this study was to determine whether daily small group intervention in the area of phonics would positively impact achievement of selected Kindergarten students enrolled in the class. The measurement tool used was the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) benchmark assessment. This study involved the use of a pre-test/post-test design to compare data from January 2013 (before the intervention was administered) to May 2014 (after the intervention was completed). Achievement gains were significant, though results could be attributable to a number of intervening factors. Research in the area of small group instruction should continue given the connection between early phonics intervention and future reading achievement.
Model of Boson and Fermion Particle Masses

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

subject: FOS: Physical sciences

description: The boson and fermion particle masses are calculated in a finite quantum field theory. The field theory satisfies Poincaré invariance, unitarity and microscopic causality, and all loop graphs are finite to all orders of perturbation theory. The infinite derivative nonlocal field interactions are regularized with a mass (length) scale parameter $Λ_i$. The $W$, $Z$ and Higgs boson masses are calculated from finite one-loop self-energy graphs. The $W^{\pm}$ mass is predicted to be $M_W=80.05$ GeV, and the higher order radiative corrections to the Higgs boson mass $m_H=125$ GeV are damped out above the regulating mass scale parameter $Λ_H=1.57$ TeV. The three generations of quark and lepton masses are calculated from finite one-loop self-interactions, and there is an exponential spacing in mass between the quarks and leptons.

description: A variety of regulations may affect commercial fish catches. We take here as a case in point steps to reduce losses of aquatic organisms due to impingement and entrainment (I&E) at power plants. Methods to evaluate the benefits of such measures are needed for benefit-cost analysis. We use a new approach to estimating ex vessel demand by Holt and Bishop (2002) to address the portion of the benefits that occur post-harvest, that is, down the marketing chain after fishermen sell their catches. The model deals with the dockside prices and quantities for six major commercial species harvested from the U.S. Great Lakes. We use the model to explore the potential magnitude of post-harvest benefits for Great Lakes fisheries. We then turn to a possible approach to benefits transfer for cases where such a model is not available. A semi-realistic case
How Students Experience Action Research

Subjects: subject: Education -- Research papers (Graduate)

description: This research and its findings examine how current students enrolled in a small liberal arts college’s action research course experience their course. The reviewed literature examines affect, stress and stress management, effects of stress, and how individuals deal with stress. Derived from the literature, interview questions were created and posed to voluntary participants. The results revealed that there are measures the college can take to further enhance the student experience both in this course and in the general program. The participants’ suggestions were funneled into one solution: the creation of a short, group orientation program held at the start of a student’s graduate career.

Feedback and metal enrichment in cosmological SPH simulations I. A model for chemical enrichment

description: We discuss a model for treating chemical enrichment by SNII and SNIa explosions in simulations of cosmological structure formation. Our model includes metal-dependent radiative cooling and star formation in dense collapsed gas clumps. Metals are returned into the diffuse interstellar medium by star particles using a local SPH smoothing kernel. A variety of chemical abundance patterns in enriched gas arise in our treatment owing to the different yields and lifetimes of SNII and SNIa progenitor stars. In the case of SNII chemical production, we adopt metal-dependent yields. Because of the sensitive dependence of cooling rates on metallicity, enrichment of galactic haloes with metals can in principle significantly alter subsequent gas infall and the build up of the stellar components. Indeed, in simulations of isolated galaxies we find that a consistent treatment of metal-dependent cooling produces 25% more stars outside the central region than simulations with a primordial cooling function. In the highly-enriched central regions, the evolution of baryons is however not affected by metal cooling, because here the gas is always dense enough to cool. A similar situation is found in cosmological simulations because we include no strong feedback processes which could spread metals over large distances and mix them into unenriched diffuse gas. We demonstrate this explicitly with test simulations which adopt super-solar cooling functions leading to large changes both in the stellar mass and in the metal distributions. We also find that the impact of metallicity on the star formation histories of galaxies may depend on their particular evolutionary history. Our results hence emphasise the importance of feedback processes for interpreting the cosmic metal enrichment.
