Masculinity, sexual identity, and the life experiences of American adolescent men
Creators: name: Easterbrook, Adam
Publisher: name: University of British Columbia

description: Demonstrating and defending one’s masculinity is an integral part of the adolescent male experience. Adolescent men earn their masculinity by engaging in performances of masculinity, which include concealing emotions, aggression, and athleticism. While men who give convincing performances of masculinity earn status and power, those who are unable to are victimized and ostracized. In this dissertation, I investigate the influence of masculinity on adolescent men’s lives through an analysis of the experiences of adolescents who participated in the National Adolescent Health study (ADD Health). My principle aim is to examine how performances of masculinity relate to important aspects of adolescents’ lives. I examine the relationship between men’s performances of masculinity and their sexual identity. Many scholars posit that heterosexuals are more masculine than non-heterosexuals. I argue that these scholars fail to take into account that men’s use of homophobia to police masculinity biases people to erroneously perceive non-heterosexuals as less masculine than heterosexuals. The analysis of the ADD Health data confirms my argument; there is no difference between heterosexual and non-heterosexual men’s masculinity. I also explore how adolescents’ performances of masculinity and sexual identity affect their relationships with peers, life satisfaction, and risk-taking. I examine these life experiences because they strongly influence adolescents’ development. The analyses indicate that concealing emotions does not strongly relate to adolescents’ life experiences. Athleticism, however, leads to better peer relationships and greater life satisfaction, while aggression has a deleterious effect on peer relationships and life satisfaction as well as increases risk-taking. Sexual identity has almost no influence on life experiences. These findings have implications for future research. First, adolescent men’s performances of masculinity entail several different sets of behaviours that each uniquely influences life experiences. Consequently, researchers need to consider masculinity as a multidimensional construct. Second, there is no evidence that non-heterosexuals are less masculine than heterosexuals. Scholars exploring sexuality and masculinity must take into account how assumptions about sexuality and masculinity might be impacting their research. Third, performances of masculinity effect several aspects of adolescent men’s lives. Future research must focus on masculinity, and not just biological sex, when attempting to understand men’s experiences.

description:
Rapid advances in genomics and bioinformatics, the vast amount of data generated by next-generation sequencing, and the penetration of the ‘-omics’ into many areas of biology have created a need for students with hands-on experience with computational and ‘big data’ methods. Additionally, laboratory experience in the isolation, identification, and characterization of unknown bacteria is a vital part of a microbiology student’s training. This lesson is a course-based undergraduate research experience (CURE) focusing on Salmonella enterica, a common and relatively low-virulence foodborne pathogen. In Module 1, students isolate and identify S. enterica strains from stream sediment, poultry litter, or other sources. They conduct phenotypic evaluation of antimicrobial resistance (AMR) and can search for plasmids. Isolates’ whole genomes may be sequenced by the United States FDA or public health laboratories, typically at no charge. In Module 2, students learn basic methods of genome assembly, analysis, annotation, and comparative genomics. They use easily accessible, primarily web-based tools to assemble their genomes and investigate areas of interest including serotype, AMR genes, and in silico evidence of mobile genetic elements. Either module can be used as a standalone learning experience. After course completion, students will be able to isolate and identify Salmonella from natural sources, and use computational analysis of microbial genomic data, particularly of the Enterobacteriaceae. This lesson offers undergraduate microbiologists a genuine research experience and a real-world microbiology application in genomic epidemiology, as well as a valuable mix of field, laboratory, and computational skills and experiences.

description: We consider two positive, normalized measures dA(x) and dB(x) related by the relationship dA(x)=(C/(x+D))dB(x) or by dA(x) = (C/(x^2+E))dB(x) and dB(x) is symmetric. We show that then the polynomial sequences {a_{n}(x)}, {b_{n}(x)} orthogonal with respect to these measures are related by the relationship a_{n}(x)=b_{n}(x)+κ_{n}b_{n-1}(x) or by a_{n}(x) = b_{n}(x) + λ_{n}b_{n-2}(x) for some sequences {κ_{n}} and {λ_{n}}. We present several examples illustrating this fact and also present some attempts for extensions and generalizations. We also give some universal identities involving polynomials {b_{n}(x)} and the sequence {κ_{n}} that have a form of Fourier series expansion of the Radon--Nikodym derivative of one measure with respect to the other.
Laserinduzierte Deformation metallischer Nanopartikel in Gläsern

Zsfassung in engl. Sprache

description: In der vorliegenden Arbeit wird gezeigt, daß intensive, ultrakurze Laserimpulse (Wellenlänge ca. 400 nm, Impulsdauer 150 fs, Impulsenergie ca. 100 µJ, typische Intensität 1012 W/cm2) in der Lage sind, Silber-Nanopartikel (Radius zwischen 5 und 50 nm), die in eine Glasmatrix eingebettet sind, dauerhaft in ihrer Form zu verändern. Um ein zunächst rundes Einzelteilchen bildet sich dabei ein Hof sehr kleiner Teilchen. Werden linear polarisierte Laserimpulse verwendet, wird zusätzlich ein länglich verformtes Zentralpartikel erzeugt, dessen lange Achse orthogonal zur Polarisation des Lasers steht. Die beschriebenen Formveränderungen der Partikel äußern sich auch im optischen Verhalten der bestrahlten Gläser: Es ergibt sich eine Rotverschiebung der charakteristischen Extinktionsbande, die durch Oberflächenplasmonen hervorgerufen wird. Bei anisotrop verformten Partikeln wird Dichroismus beobachtet, d.h. die optischen Eigenschaften der Probe sind abhängig von der Polarisation der Beleuchtung. Die vorliegende Arbeit beschreibt weiterhin Abhängigkeit der optischen Eigenschaften metallischer Nanopartikel in Glasmatrix von einer Reihe von Laserparametern, so z.B. Wellenlänge, Anzahl der Impulse, Intensität und Polarisation. Zur Aufklärung des Zeitverhaltens der Verformung wurden Pump-Probe-Experimente durchgeführt, die zeigen, daß bei Laserintensitäten, bei denen irreversible Veränderungen der Proben auftraten, charakteristische neue Zeitkonstanten zu beobachten sind.
description: In the thesis presented here it is shown that intense, ultra-short laser pulses (wavelength 400 nm, pulse duration 150 fs, pulse energy ca. 100 µJ, typical intensity 1012 W/cm2) induce permanent deformations of silver nanoparticles embedded in a glass matrix. An initially single spherical particle shows a halo of small silver particles after irradiation. When linearly polarized laser pulses are used, the central particle shows an elongated form, where the long axis is orthogonal to the laser polarization. The described particle deformations are also represented in changes of the optical spectra of the glass samples: The characteristic extinction band caused by surface plasmons is red-shifted after laser irradiation. Dicroism appears when anisotropic particles are created, i.e. the optical behaviour of the sample depends on the polarization of the illumination. This work describes additionally the dependence of the optical spectra on different laser parameters such as wavelength, number of pulses, intensity and polarization. In order to investigate the time scales on which deformation occurs, pump-probe-experiments were performed which show that new time constants appear, when the laser intensity is high enough that irreversible changes of the samples are induced.
InP microelectronics reaching maturity

description: While InP and the related (lattice matched) compounds are now well established in long wavelength (1.3 - 1.55 um) optoelectronics owing to their unmatched light emission properties, these materials are still fighting for a niche in microelectronics. InP and In0.53Ga0.47As, with a composition lattice matched to InP, obviously exhibit very attractive electronic transport properties, with respect to Si and GaAs. However the maturity of InP technology has been trailing considerably GaAs development, so that InP microelectronic devices and ICs are still more at the research and development stage than ready for large scale production. This paper is intended to show how the current progress in InP and related materials growth and process technologies now allows to benefit from their intrinsic electronic properties for the fabrication of high performance devices, ICs and OEICs.

description: Gegenstand der vorliegenden Arbeit ist die Untersuchung des Einflusses verschiedener Zusatzkomponenten auf die texturellen, festkörperchemischen und katalytischen Eigenschaften des Aluminiumoxidträgermaterials und der daraus resultierenden Katalysatorsysteme. Die Herstellung des Aluminiumoxid-Trägermaterials erfolgte mit der neuen Methode der Thermoschockcalcination nahezu abproduktfrei. Im Ergebnis sind thermisch stabile Systeme (Ni-Al2O3-MxOy; M: Ti, Cr, Mo, W, Y, Ce) entstanden, die sich durch eine veränderte Oberflächenstruktur und durch veränderte Wechselwirkungen des Trägermaterials mit den Aktivkomponenten auszeichnen. Die katalytischen Eigenschaften des Systems Al2O3 können so recht drastisch verändert werden. Die Auswahl eines entsprechenden Herstellungsprozesses für den Katalysatorträger, eine gezielte Modifizierung des Trägermaterials und die Präparationsmethode können also zu einer gezielten Veränderung der Eigenschaften eines Katalysatorsystems genutzt werden.
description: This dissertation focuses on studies of aluminum oxide matrices that were produced through rapid calcination of aluminum hydroxide, followed by rehydration, without almost any chemical byproducts. Rehydration with several different metal compounds results in products with clearly changed characteristics. In order to obtain a broad overview of possible changes in the matrix, water-soluble compounds of titanium, chromium, molybdenum, tungsten, cerium and yttrium were used as initiators, and, in addition, nickel was used as an activator. It can be shown that the structural and catalytic characteristics of the catalytic Ni-Al2O3 system can be modified in many different ways through specific modifications of the metal catalyst as well as by the use of different preparation methods.

description: Ziel dieser Arbeit war es zu prüfen, ob syn- oder metachron auftretende seröse Borderline-Tumoren (S-BOTs) des Ovars und extraovarielle, meist peritoneale Implants (IMPs) aus einem gemeinsamen Klon entstehen oder verschiedene Progenitorzellen haben. Dazu wurde paraffiniertes Tumormaterial von 12 geeigneten Patientinnen verwendet. Die isolierte DNA der 19 ovariellen und 43 extraovariellen Gewebeproben wurde im Bereich von 10 Mikrosatelliten amplifiziert. Nach semiquantitativer Beurteilung im Agarosegel und Vorbereitung der Proben wurden die Fragmente in einem Polyacrylamidgel elektrophoretisch aufgetrennt und mittels Silberfärbung sichtbar gemacht. Auf diese Weise konnte ein Vergleich der Bandenmuster der multifokalen Tumorproben erfolgen. Von den 10 Mikrosatellitenmarkern deckten 8, in höchstem Maße MYC-L1, bei insgesamt 43,5% der Proben Unterschiede im Sinne von allelischen Imbalancen oder Mikrosatelliteninstabilitäten auf. 5 Fälle (41,7%) wiesen bei 9-10 Markern ein einheitliches, also konkordantes Muster auf, welches entweder dem Wildtyp oder einer klonal weitergegebenen Mutation entsprechen könnte. In 58,3% der Fälle unterschieden sich BOT- und IMP-Proben in mindestens 2 Markern, was als Diskordanz definiert wurde. Diese deutet am ehesten auf einen polyklonalen Ursprung hin. Innerhalb der diskordanten Fälle ließen sich jedoch 4 Serien genotypisch gleicher Proben ausmachen, von denen 3 ausschließlich Implants betrafen und eine sowohl den linksseitigen BOT als auch einen Teil der assoziierten Implants. Von den 7 Patientinnen mit bilateralen S-BOTs zeigten 28,6% Unterschiede zwischen rechts- und linksovariellem Tumor; 71,4% hatten beidseits ein identisches Muster. In die Interpretation der Ergebnisse wurden zusätzlich Sequenzierungen im Bereich zweier Protoonkogene (K-RAS und B-RAF) einbezogen. Diese deckten 4 Mutationen im Codon 12 des K-RAS-Gens auf (9,7% der Proben, 1/3 der Fälle). Davon betraf nur eine sowohl die ovariellen Tumorherde als auch zumindest einen der extraovariellen. Unter Berücksichtigung der Ergebnisse beider Methoden bietet dieser Fall die deutlichsten Hinweise auf den klonalen Ursprung eines Implants aus dem entsprechenden BOT. Insgesamt finden sich jedoch mehr Indizien für eine vom BOT unabhängige, polyklonale Entstehung der Implants. Angesichts der allgemeinen Studienlage ist die Koexistenz beider Pathomechanismen anzunehmen. Eine abschließende Klärung der Fragestellung wird nur mit Hilfe weiterer Untersuchungen möglich sein.

description: We discuss how the thermalization of an elementary quantum system is modified when the system is placed in an environment out of thermal equilibrium. To this aim we provide a detailed investigation of the dynamics of an atomic system placed close to a body of arbitrary geometry and dielectric permittivity, whose temperature $T_M$ is different from that of the surrounding walls $T_W$. A suitable master equation for the general case of an $N$-level atom is first derived and then specialized to the cases of a two- and three-level atom. Transition rates and steady states are explicitly expressed as a function of the scattering matrices of the body and become both qualitatively and quantitatively different from the case of radiation at thermal equilibrium. Out of equilibrium, the system steady state depends on the system-body distance, on the geometry of the body and on the interplay of all such parameters with the body optical resonances. While a two-level atom tends toward a thermal state, this is not the case already in the presence of three atomic levels. This peculiar behavior can be exploited, for example, to invert the populations ordering and to provide an efficient cooling mechanism for the internal state of the quantum system. We finally provide numerical studies and asymptotic expressions when the body is a slab of finite thickness. Our predictions can be relevant for a wide class of experimental configurations out of thermal equilibrium involving different physical realizations of two or three-level systems.

description: Previous foot-and-mouth disease (FMD) outbreaks and simulation-based analyses suggest substantial payoffs from detecting an incursion early. However, no economic measures for early detection have been analysed in an optimising framework. We investigate the use of bulk milk testing (BMT) for active surveillance against an FMD incursion in Australia. We find that BMT can be justified, but only when the FMD entry probability is sufficiently high or the cost of BMT is low. However, BMT is well suited for post-outbreak surveillance, to shorten the length of time and size of an epidemic and to facilitate an earlier return to market.

description: Hintergrund: Imatinib-Mesylat und Dasatinib werden bereits erfolgreich bei der Therapie von einigen Tumoren wie CML, GIST und Sarkomen eingesetzt. Da Neuroblastome auch potentielle Zielstrukturen der Tyrosinkinaseinhibitoren wie KIT oder PDGFR-Kinasen exprimieren, sollte eine mögliche Anwendung dieser Substanzen bei Neuroblastomen untersucht werden. Methoden: Anhand von in-vitro-Studien mit der Neuroblastomzelllinie SH-SY5Y wurde durch Zellproliferationstests die Effektivität einer Tyrosinkinaseinhibitor-Behandlung untersucht. Durch eine Langzeitbehandlung mit Imatinib-Mesylat und Dasatinib wurden resistente Tumorzellen gewonnen. Mittels DNA-Microarrayanalysen, konventioneller und quantitativer Polymerasekettenreaktion sowie Durchflusszytometrie wurden Unterschiede in der Genexpression von behandelten Tumorzellen im Vergleich zu unbehandelten Tumorzellen herausgearbeitet. Ergebnisse: Sowohl Imatinib-Mesylat (ED50=31µM) als auch Dasatinib (ED50=10µM) zeigten einen hemmenden Einfluss auf die Tumorzellproliferation. Jedoch besaß Dasatinib eine höhere Effektivität, selbst bei Imatinib-Mesylat resistenten Zellen (ED50=18µM). Durch die Behandlung mit beiden Tyrosinkinaseinhibitoren kam es zu Veränderungen in der Genexpression bei Neuroblastom-Zellen, insbesondere bei Genen mit Bezug zum Interferon-Signalweg. Schlussfolgerung: Imatinib-Mesylat und besonders Dasatinib könnten bei therapieresistenten oder fortgeschrittenen Neuroblastomen gegebenenfalls auch zur Ergänzung von Chemotherapie eine mögliche Therapieoption darstellen. Aufgrund der komplexen Auswirkungen von Tyrosinkinaseinhibitoren auf die Genexpression von Neuroblastomzellen erscheinen weitergehende Untersuchungen zu den Wirkmechanismen der genannten Inhibitoren wünschenswert.

description: It was recently recognized that interdependencies among different networks can play a crucial role in triggering cascading failures and hence system-wide disasters. A recent model shows how pairs of interdependent networks can exhibit an abrupt percolation transition as failures accumulate. We report on the effects of topology on failure propagation for a model system consisting of two interdependent networks. We find that the internal node correlations in each of the two interdependent networks significantly changes the critical density of failures that triggers the total disruption of the two-network system. Specifically, we find that the assortativity (i.e. the likelihood of nodes with similar degree to be connected) within a single network decreases the robustness of the entire system. The results of this study on the influence of assortativity may provide insights into ways of improving the robustness of network architecture, and thus enhances the level of protection of critical infrastructures.

description: In this paper, a 5Kb it ROM is presented us­ing a primitive-cell architecture based on a compensation technique, named Low Leakage Current FET Circuit (L2FC), whose main advantage relies on the fact that it has an ex­tremely low noise margin sensitivity with fan-in compared with Direct Coupled FET logic (DCFL). This characteristic is found to be the key factor when implementing GaAs ROMs because of its degradation as the number of word lines is increased. The performance obtained using this structure demonstrates the effectivenes of this technique and its significant improvement on noise margin increase.
Homa Bay Memories : using research-based theatre to explore a narrative inheritance
Creators: name: Lea, Graham Walter
Publisher: name: University of British Columbia
Year: 2013

description: In her article When Missions Became Development: Ironies of ‘NGOization’ in Mainstream Canadian Churches in the 1960s (2010), Ruth Compton Brouwer discusses the move from a missionary to a secular focus in international development. To personalize this transition she tells the story of a high-school friend who, instead of following her uncle into missionary work, joined a secular Non-Governmental Organization to teach in Kenya. Compton Brouwer’s unnamed friend was my mother and the stories of her Kenyan experiences became a significant part of my narrative inheritance (Goodall, 2005). Inspired by these stories I engaged with my narrative inheritance, travelling to, and teaching in Kenya as a part of my teacher training. At the heart of this dissertation is Homa Bay Memories, a theatrical script developed using research-based theatre and narrative inquiry to explore my and my mother’s Kenyan experiences almost forty years apart. This exploration is based on letters, photos, and audio recordings left behind by my mother after her death as well as artifacts and memories of my Kenyan experiences. Through this scripted research I seek a deeper understanding of a little known but influential part of my mother’s life and how her experience has, and continues to, shape my life. Developing the script Homa Bay Memories also provided an opportunity to critically engage with research-based theatre as a methodology. Saldaña (2010) notes a lack of accounts detailing the development and “critical decision-making processes” (p. 4) encountered in research-based theatre projects. I address this gap through a careful examination of the development of Homa Bay Memories. The methodological exploration becomes the spine of this dissertation as I closely examine key moments, tensions, and decisions I faced while crafting and conceptualizing this research for the stage. These experiential and methodological contributions are theoretically informed by Bakhtin’s notion of chains of utterances (1986). This theoretical lens suggests a relentless rationality and “unfinalizability” (Holquist, 2002, p. 195) that characterizes both the understandings and presentation of the research. The dissertation concludes by suggesting possible evaluative entry points into the work.

Radiative transfer effects during primordial helium recombination

description: In this paper we refine the calculation of primordial helium recombination, accounting for several additional effects that were neglected or treated more approximately in previous studies. These include consideration of (i) time-dependent radiative transfer interaction between the 2^1 P_1 - 1^1 S_0 and 2^3 P_1 - 1^1 S_0 resonances; (ii) time-dependent radiative transfer for the partially overlapping n^1 P_1 - 1^1 S_0, n^1 D_2 - 1^1 S_0 and n^3 P_1 - 1^1 S_0 series with 3 <= n <= 10; (iii) electron scattering within a kernel approach. We also briefly discuss the effect of electron scattering and HI quadrupole lines on the recombination of hydrogen. Although the physics of all the considered processes is interesting and subtle, for the standard cosmology, with Y_p \sim 0.24, the overall correction to the ionization history during helium recombination with respect to the previous implementation of CosmoRec remains smaller than |DeltaNe/Ne| \sim 0.05%. The dominant improvement is caused by consistent inclusion of resonance scattering for the 2^1 P_1 - 1^1 S_0 resonance. For cosmologies with a large helium fraction, Y_p \sim 0.4, the difference reaches |D N_e/N_e|\sim 0.22% at z\sim1800, however, the overall correction to the CMB power spectra is small, exceeding |D C_l/C_l| \sim 0.05 % only at l>\sim 3000. In comparison to the current version of Recfast the difference reaches |D C_l/C_l|\sim0.4% at l\sim 3000 for Y_p \sim 0.4, and also for the standard value Y_p \sim 0.24 we find differences |DC_l/C_l|>\sim 0.1% at l\sim 2500. The new processes are now included by the cosmological recombination code CosmoRec and can be activated as needed for most settings without affecting its runtime significantly.

We also construct explicitly a proper subset of $\mathbb{C}^m$ in terms of the Newton polyhedrons of $F_1, F_2, ..., F_m$ and show that it contains the bifurcation set of $F$. In the case $m= n-1$ we show that $F$ is a locally $C^{\infty}$-trivial fibration if and only if it is a locally $C^0$-trivial fibration.

description: Treating grazing pressure as an undesirable output of livestock grazing in a directional distance function improves understanding of how economic behaviour affects the environment. Field survey data from 193 livestock grazing households combined with remotely sensed net primary productivity (NPP) data on the Qinghai–Tibetan–Plateau was used to develop a directional output-orientation distance function. The average efficiency of livestock grazing households is 0.817 when incorporating grazing pressure as an undesirable output, which means that households can achieve 18.3% more output and decrease proportional grazing pressure holding all inputs fixed. The relative shadow price of undesirable grazing pressure to good output grazing revenue is estimated to be between 1.795 and 3.986. According to the Morishima elasticity of substitution between inputs, there is a significant complementary relationship between grassland, labour and capital.

description: Several image coding and compression schemes based on Mathematical Morphology have been documented in the literature including: morphological skeleton coding [1], multiresolution analysis [2], morphological pyramid coding [3,4], morphological subband coding [5,6], and segmenta­tion-based coding using the watershed transform [7,8]. The advantages of the morphological approach over more traditional linear methods are: low computational com­plexity, inherent parallelism, and elimination of the ring­ing and blurring associated with linear techniques such as linear subband coding and transform coding using the dis­crete cosine transform (the latter is used in JPEG and MPEG). Morphological compression algorithms rely on two basic transformations: the dilation and the erosion. Hardware implementation of these operations is needed to realise the computational speed required for the real time processing of video. This paper proffers specifications for a video rate VLSI processor and examines the throughput and organisation for an implementation in 0.5 um GaAs technology.

description: Die Untersuchung geht der Frage nach, wie sich die deutsche Außenpolitik zwischen 1994 und 2002 gegenüber den drei baltischen Staaten Estland, Lettland u. Litauen gestaltete. Konkreter empirischer Forschungsgegenstand ist die gegenüberstellende Analyse der Außenpolitik der Regierung Kohl (1994-1998) und der Regierung Schröder (1998-2002). Auf der Grundlage eines Input-Output-Models werden die für die Außenpolitikgestaltung relevanten Akteure geortet, deren Interessen und Forderungen lokalisiert und wichtige Entscheidungen auf bilateraler und multilateraler Ebene analytisch greifbar gemacht. Zur Einordnung der Untersuchungsergebnisse dienen drei wichtige Theorien der Internationalen Beziehungen: Die unterschiedlichen konzeptionellen Vorstellungen des Realismus, des Liberalismus und des Konstruktivismus geben das Raster vor. Es wird erarbeitet, wie die einzelnen theoretischen Konzepte mit der realen deutschen Außenpolitikgestaltung gegenüber den baltischen Staaten harmonierten bzw. ob sich mit dem Regierungswechsel 1998 in Deutschland, auch eine Veränderung in den außenpolitischen Präferenzen verbinden lässt.
description: This thesis defines the manner how Germany's Baltic policy (Baltic States= Estonia. Latvia and Lithuania) was practiced between 1994 and 2002. The concrete empirical object of research is the opposing analysis of German foreign policy by the German chancellors Helmut Kohl (1994-1998) and Gerhard Schröder (1998-2002). On the basis of an input-output model, the protagonists of foreign policy are listed, their interests and demands identified and important decisions made available analytically at a bilateral and multilateral level. Three important theories of the international relations help to classify the findings: The different conceptual ideas of realism, liberalism and constructivism provide the basis. It is worked out how the single theoretical concepts accord with Germany's Baltic policy in reality and if there was not just a change in Germany's foreign policy in 1998, but also in its external (political) preferences.

description: This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory-price auction and a uniform-price ascending auction, and four bid selection criteria on the basis of: total bid, bid-per-value ratio, bid-per-area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid-per-value ratio. We develop a best-response group-bidding model for a discriminatory-price auction where bidders form optimal group bids for individual wildlife zones. In the uniform-price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio-economic model of malleefowl conservation, we observe that the discriminatory-price auction is more cost-effective than the uniform-price ascending auction. However, the budgetary cost-effectiveness of a discriminatoryprice auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.

description: We study the effects of high magnetic fields on the particle population and equation of state of hybrid stars using an extended hadronic and quark SU(3) non-linear realization of the sigma model. In this model the degrees of freedom change naturally from hadrons to quarks as the density and/or temperature increases. The effects of high magnetic fields and anomalous magnetic moment are visible in the macroscopic properties of the star, such as mass, adiabatic index, moment of inertia, and cooling curves. Moreover, at the same time that the magnetic fields become high enough to modify those properties, they make the star anisotropic.

description: We consider random walks on $\Z^d$ among nearest-neighbor random conductances which are i.i.d., positive, bounded uniformly from above but whose support extends all the way to zero. Our focus is on the detailed properties of the paths of the random walk conditioned to return back to the starting point at time $2n$. We show that in the situations when the heat kernel exhibits subdiffusive decay --- which is known to occur in dimensions $d\ge4$ --- the walk gets trapped for a time of order $n$ in a small spatial region. This shows that the strategy used earlier to infer subdiffusive lower bounds on the heat kernel in specific examples is in fact dominant. In addition, we settle a conjecture concerning the worst possible subdiffusive decay in four dimensions.

description: This paper describes a new GaAs MESFET structure, named Differential Cross-Coupled FET Logic - DC2FL, which is compatible with DCFL, DPTL and DCVS circuits. It can be efficiently used in delay-insensitive asynchronous circuits and self-timed rings, as well as in synchronous ones. When combined with the mentioned differential structures it offers attractive power savings without performance degradation. As an example, a fully functional 8-bit ripple carry adder has been designed and fabricated, verifying the expected very low power dissipation during the standby state.

description: Human capital is an important resource in primary production impacting on farmers’ decisions and actions. Given their current and expected economic environment, farmers must use their human capital in mapping out a trajectory for their farm. This study considers particular aspects of farmers’ human capital and its influence on farm growth, or lack of it. Farmers’ characteristics as expressed through their personality, intelligence and objectives are the main human capital aspects considered in a sample of smaller NZ dairy farms. They are somewhat typical of western farmers working on smaller farms. They can be broadly classed into Expanders, Maintainers and Retractors. It is hypothesised each group will have distinct and different personal characteristics and these influence the farmers’ choice of trajectory. This is in addition to purely economic factors. It is also hypothesised the characteristics influence the farmers’ choice of development strategy and how challenges to the strategy are viewed. The data collected from the small dairy farms support the hypotheses suggesting the design of policy and extension programs must allow for these human capital drivers. Using past data, it is also shown aspects of human capital are different in large farms emphasising the same conclusion.

description: It has been recently proposed by Dvali et al that high energy scattering in non-renormalizable theories, like the higgsless Standard Model, can be unitarized by the formation of classical configurations called classicalons. In this work we argue that classicalons should have analogs of thermodynamic properties like temperature and entropy and perform a model-independent statistical mechanical analysis of classicalon decays. We find that, in the case of massless quanta, the decay products have a Planck distribution with an effective temperature T~1/r_* where r_* is the classicalon radius. These results, in particular a computation of the decay multiplicity, N_*, allow us to make the first collider analysis of classicalization. In the model for unitarization of WW scattering by classicalization of longitudinal Ws and Zs we get spectacular multi-W/Z final states that decay into leptons, missing energy and a very high multiplicity (at least 10) of jets. We find that for the classicalization scale, M_* = v=246 GeV (M_*=1 TeV) discovery should be possible in the present 7 TeV (14 TeV) run of the LHC with about 10 /fb (100 /fb) data. We also consider a model to solve the hierarchy problem, where the classicalons are configurations of the Higgs field which decay into to multi-Higgs boson final states. We find that, in this case, for M_*=500 GeV (M_*=1 TeV), discovery should be possible in the top fusion process with about 10 /fb (100 /fb) data at 14 TeV LHC.
