Towards a genealogy of the mentor in early career teacher mentorship programs
Creators: name: Hales, Anne Catherine
Publisher: name: University of British Columbia
Year: 2021

description: This dissertation is an exploration of the aims and effects of early career teacher mentorship and the role of teacher mentors in public education policy and program contexts. This project was provoked by an ethic of discomfort (Foucault, 1994) with how teacher mentorship is commonly framed as a strategy for addressing a variety of new teacher ‘problems’ including career attrition, isolation, ineffective practice and lack of collegial support. In particular, the study aimed to problematize the invocation of teacher mentorship as a site for cultivating professional growth and lifelong learning. The purpose of this study was to construct a conceptual lineage of ECT mentorship in British Columbia, Canada in order to denaturalize normalized understandings of mentorship and mentor figures at work in one school district mentorship program. Through genealogical and discourse analysis of policy and programs documents and policy actor interviews generated between 1960-2019, the two research questions addressed were: 1) how a Foucauldian-inspired analysis of discourse-practices might illuminate dominant truths in circulation about the aims of ECT mentorship, and 2) how the teacher mentor is discursively constituted as a subject within mentoring programs and relationships. This study’s genealogical policy analysis showed how mentorship became thinkable as a professional undertaking and was assigned various purposes across shifting historical and political circumstances in British Columbia’s public education system. Meanwhile, discourse analysis of policy actors’ and mentors’ speech and written statements illustrated how commonly circulated imperatives of early career teacher mentorship and the mentor role remained open to critical contestation and reformation. Analysis indicated how teacher mentors working with a formal program structure became subject to particular discourses of ‘growth’ as good and desirable, as the improvement of instructional competency, and as a regulatory strategy committing both mentors and mentees to a trajectory of lifelong learning. The study points to how those engaged in ECT mentorship research, policymaking and practice might submit normalized imperatives of ECT mentorship to regular critical interrogation and to reimagine mentors’ potential roles as creative, critical and reflective educators.

description: The following distributed coalescence protocol was introduced by Dahlia Malkhi in 2006 motivated by applications in social networking. Initially there are n agents wishing to coalesce into one cluster via a decentralized stochastic process, where each round is as follows: every cluster flips a fair coin to dictate whether it is to issue or accept requests in this round. Issuing a request amounts to contacting a cluster randomly chosen proportionally to its size. A cluster accepting requests is to select an incoming one uniformly (if there are such) and merge with that cluster. Empirical results by Fernandess and Malkhi suggested the protocol concludes in O(log n) rounds with high probability, whereas numerical estimates by Oded Schramm, based on an ingenious analytic approximation, suggested that the coalescence time should be super-logarithmic. Our contribution is a rigorous study of the stochastic coalescence process with two consequences. First, we confirm that the above process indeed requires super-logarithmic time w.h.p., where the inefficient rounds are due to oversized clusters that occasionally develop. Second, we remedy this by showing that a simple modification produces an essentially optimal distributed protocol; if clusters favor their smallest incoming merge request then the process does terminate in O(log n) rounds w.h.p., and simulations show that the new protocol readily outperforms the original one. Our upper bound hinges on a potential function involving the logarithm of the number of clusters and the cluster-susceptibility, carefully chosen to form a supermartingale. The analysis of the lower bound builds upon the novel approach of Schramm which may find additional applications: rather than seeking a single parameter that controls the system behavior, instead one approximates the system by the Laplace transform of the entire cluster-size distribution.

Governing Innovation and Expression: New Regimes, Techniques and Strategies

Publisher: name: Nordic Journal of Commercial Law

description: New multi-party agreements have changed the international intellectual property law landscape and increased its global impact. Two central actors, the EU and the US routinely leverage their bargaining strength by including extensive intellectual property chapters in their bilateral agreements with developing countries. A shift in international intellectual property law-making seems apparent. Stagnated multi-lateral processes in established forums such as the World Intellectual Property Organization (WIPO) and the World Trade Organization (WTO) are abandoned and issues are shifted to faster side-tracks unburdened with even semi-open or semidemocratic decision-making. The pace of generating intellectual property norms with general or global effect thus remains high, but keeping step with contemporary legal problems has legitimacy costs. We also see a topical shift, where more general and controversial issues are decided in these new forums. Are these norms open to scrutiny from the rest of the legal system? Substantive intellectual property law-making is also in flux on the national and regional level. Patent laws are under reform in the EU and the US. Furthermore, the changing political and societal role of social media raises questions related to privacy and more generally the regulation of internet-based expression and communication. Social networks and location services challenge data protection and privacy laws. At the same time, criminal enforcement of intellectual property rights proliferates and the threat of damages may assume the role of a deterrent. The question of whether intellectual property rights holders may target internet service providers instead of direct infringers poses a direct challenge to our virtual infrastructure. New bottlenecks and gatekeepers emerge continuously. What are the legal hurdles social networks and internet service providers currently face? How should they be regulated – and why? The focus of the book is on new regimes, strategies and techniques in regulating such recent and on-going changes. The authors ask whether such reforms are “business as usual” or whether they could signify more fundamental changes in the way innovation, creativity and especially Internet-based expression are governed globally and locally. The book is divided in three parts under the following themes: New Innovation and Intellectual Property Regimes; Governing the Internet and Social Networks; and New Strategies and Techniques of Enforcement.

description: We explore the phase diagram of two-component bosons with Feshbach resonant pairing interactions in an optical lattice. It has been shown in previous work to exhibit a rich variety of phases and phase transitions, including a paradigmatic Ising quantum phase transition within the second Mott lobe. We discuss the evolution of the phase diagram with system parameters and relate this to the predictions of Landau theory. We extend our exact diagonalization studies of the one-dimensional bosonic Hamiltonian and confirm additional Ising critical exponents for the longitudinal and transverse magnetic susceptibilities within the second Mott lobe. The numerical results for the ground state energy and transverse magnetization are in good agreement with exact solutions of the Ising model in the thermodynamic limit. We also provide details of the low-energy spectrum, as well as density fluctuations and superfluid fractions in the grand canonical ensemble.

description: The use of telehealth within music therapy practice has increased through necessity in recent years. To contribute to the evolving evidence base, this current study on Telehealth Music Therapy (TMT) was undertaken to investigate the telehealth provision experiences of music therapists internationally. Participants completed an anonymous online cross-sectional survey covering demographics, clinical practice, telehealth provision, and telehealth perceptions. Descriptive and inferential statistics, in combination with thematic analysis, were used to analyze the data. A total of 572 music therapists from 29 countries experienced in providing TMT took part in this study. The results showed that the overall number of clinical hours (TMT and in-person hours combined) declined due to the pandemic. Participants also reported reduced perceived success rates in utilizing both live and pre-recorded music in TMT sessions when compared to in-person sessions. Although many music therapists rose to the challenges posed by the pandemic by incorporating TMT delivery modes, there was no clear agreement on whether TMT has more benefits than drawbacks; however, reported benefits included increased client access and caregiver involvement. Furthermore, a correlation analysis revealed moderate-to-strong positive associations between respondents who perceived TMT to have more benefits than drawbacks, proficiency at administering assessments over telehealth, and perceived likelihood of using telehealth in the future. Regarding the influence of primary theoretical orientation and work setting, respondents who selected music psychotherapy as a primary theoretical orientation had more experience providing TMT prior to the pandemic while those primarily working in private practice were most inclined to continue TMT services post-pandemic. Benefits and drawbacks are discussed and future recommendations for TMT are provided.

description: Taylor-Wiles type lifting theorems allow one to deduce that for $ρ$ a "sufficiently nice" $l$-adic representation of the absolute Galois group of a number field whose semi-simplified reduction modulo $l$, denoted $\overlineρ$, comes from an automorphic representation then so does $ρ$. The recent lifting theorems of Barnet-Lamb-Gee-Geraghty-Taylor impose a technical condition, called \emph{$m$-big}, upon the residual representation $\overlineρ$. Snowden-Wiles proved that for a sufficiently irreducible compatible system of Galois representations, the residual images are \emph{big} at a set of places of Dirichlet density $1$. We demonstrate the analogous result in the \emph{$m$-big} setting using a mild generalization of their argument.

description: The XENON100 experiment, located at the Laboratori Nazionali del Gran Sasso (LNGS), aims to directly detect dark matter in the form of Weakly Interacting Massive Particles (WIMPs) via their elastic scattering off xenon nuclei. We present a comprehensive study of the predicted electronic recoil background coming from radioactive decays inside the detector and shield materials, and intrinsic contamination. Based on GEANT4 Monte Carlo simulations using a detailed geometry together with the measured radioactivity of all detector components, we predict an electronic recoil background in the WIMP-search energy range (0-100 keV) in the 30 kg fiducial mass of less than 10e-2 events/(kg-day-keV), consistent with the experiment's design goal. The predicted background spectrum is in very good agreement with the data taken during the commissioning of the detector, in Fall 2009.

description: The Chew-Mandelstam parameterization, which has been used extensively in the two-body hadronic sector, is generalized in this exploratory study to the electromagnetic sector by simultaneous fits to the pion- and eta-photoproduction S-wave multipole amplitudes for center-of-mass energies from the pion threshold through 1.61 GeV. We review the Chew-Mandelstam parameterization in detail to clarify the theoretical content of the SAID hadronic amplitude analysis and to place the proposed, generalized SAID electromagnetic amplitudes in the context of earlier employed parameterized forms. The parameterization is unitary at the two-body level, employing four hadronic channels and the gamma-N electromagnetic channel. We compare the resulting fit to the MAID parameterization and find qualitative agreement though, numerically, the solution is somewhat different. Applications of the extended parameterization to global fits of the photoproduction data and to global fits of the combined hadronic and photoproduction data are discussed.

Procuro mostrar que a sátira, operada pelo narrador, desmonta o nacionalismo utópico do Major Quaresma. Em vista disso, suponho também que a própria linguagem do romance elabora a subjetividade estética anti-romântica formulada em Quaresma, posto que esta retoma o signo nacional para desfigurá-lo e, dessa forma, expõe como a arte literária aponta uma fratura na experiência representativa da linguagem na história da Literatura Brasileira.

description: In genome-wide association studies (GWAS), hundreds of thousands of genetic markers (SNPs) are tested for association with a trait or phenotype. Reported effects tend to be larger in magnitude than the true effects of these markers, the so-called ``winner's curse.'' We argue that the classical definition of unbiasedness is not useful in this context and propose to use a different definition of unbiasedness that is a property of the estimator we advocate. We suggest an integrated approach to the estimation of the SNP effects and to the prediction of trait values, treating SNP effects as random instead of fixed effects. Statistical methods traditionally used in the prediction of trait values in the genetics of livestock, which predates the availability of SNP data, can be applied to analysis of GWAS, giving better estimates of the SNP effects and predictions of phenotypic and genetic values in individuals.

Intellectual Property Protection for Computer Programs: Developments, Challenges and Pressure for Change
Creators: name: Ballardini, Rosa Maria
Publisher: name: Nordic Journal of Commercial Law
Year: 2013

description: This book is a study of how computer programs have challenged the thinking about and the actual use of intellectual property rights (IPRs) around the world. In general, the intellectual property (IP) system is governed by the same rules and applies equally to all fields of developments. However, the particular nature of computer software has challenged these fundamentals. Software is a pluralistic product that contains several elements, each of which could fall into different categories of IP laws. Computer programs can be defined as “a combination of computer instructions and data definitions that enable computer hardware to perform computational or control functions”1. IP protection applies differently depending on the manner in which those instructions and definitions are expressed. Currently, several protection mechanisms are available for software, including copyright, patents, trademarks, contracts, licensing agreements, and technical measures of protection. It has been suggested that none of these mechanisms, if used individually, successfully provide an adequate level of protection to computer programs. Software technology started to appear during the 1950s, when the first computer programs were developed. As soon as it became evident that computer software was a highly complex technology that required large monetary investments, both a wide market for software and significant potential for monetary rewards were envisaged. Debates regarding the adequacy of the existing protection mechanisms for software were then initiated. It became immediately clear that each of the existing IP protection mechanisms possessed certain limitations when applied to software. These problems have generated a global debate regarding the extent to which software should be afforded IP protection. Several perspectives have been presented, and a large variety of solutions have been proposed. Some of the proposals embrace rather extremist views. For example, some suggest the complete abolition of IP protection for software in favour of an IP-free regime or the development of a completely new protection mechanism tailored to the special needs of software. In contrast, others see the IP system as playing an extremely important role in securing investments and ensuring progress in the software field and thus advocate a strong level of protection. In addition, several more balanced proposals have been launched, many of which have attempted to shape the existing IP rules such that they meet the needs of computer software. This thesis effectively contributes to this debate by providing a number of balanced, reasonable, and feasible answers to some of the major issues in the software intellectual property ecosystem. The proposed solutions were generated within the framework of the currently existing body of IP laws.

description: Recently, in the series of works a new effect of acceleration of particles by black holes was found. Under certain conditions, the energy in the centre of mass frame can become infinitely large. The essential ingredient of such effect is the rotation of a black hole. In the present Letter, we argue that the similar effect exists for a nonrotating but charged black hole even for the simplest case of radial motion of particles in the Reissner-Nordström background. All main features of the effect under discussion due to rotating black holes have their counterpart for the nonrotating charged ones.

description: In a general time-dependent (3+1)-dimensional spherically symmetric spacetime, the so-called Kodama vector is a naturally defined geometric quantity that is timelike outside the evolving horizon and so defines a preferred class of fiducial observers. However the Kodama vector does not by itself define any preferred notion of time. We first extract as much information as possible by invoking the "warped product" structure of spherically symmetric spacetime to study the Kodama vector, and the associated Kodama energy flux, in a coordinate independent manner. Using this formalism we construct a general class of conservation laws, generalizing Kodama's energy flux. We then demonstrate that a preferred time coordinate - which we shall call Kodama time - can be introduced by taking the additional step of applying the Clebsch decomposition theorem to the Kodama vector. We thus construct a geometrically preferred coordinate system for any time-dependent spherically symmetric spacetime, and explore its properties. We study the geometrically preferred fiducial observers, and demonstrate that it is possible to define and calculate a generalized notion of surface gravity that is valid throughout the entire evolving spacetime. Furthermore, by building and suitably normalizing set of radial null geodesics, we can show that this generalized surface gravity passes several consistency tests and has a physically appropriate static limit.

description: Casimir forces can appear between intrusions placed in different media driven by several fluctuation mechanisms, either in equilibrium or out of it. Herein, we develop a general formalism to obtain such forces from the dynamical equations of the fluctuating medium, the statistical properties of the driving noise, and the boundary conditions of the intrusions (which simulate the interaction between the intrusions and the medium). As a result, an explicit formula for the Casimir force over the intrusions is derived. This formalism contains the thermal Casimir effect as a particular limit and generalizes the study of the Casimir effect to such systems through their dynamical equations, with no appeal to their Hamiltonian, if any exists. In particular, we study the Casimir force between two infinite parallel plates with Dirichlet or Neumann boundary conditions, immersed in several media with finite correlation lengths (reaction--diffusion system, liquid crystals, and two coupled fields with non-Hermitian evolution equations). The driving Gaussian noises have vanishing or finite spatial or temporal correlation lengths; in the first case, equilibrium is reobtained and finite correlations produce nonequilibrium dynamics. The results obtained show that, generally, nonequilibrium dynamics leads to Casimir forces, whereas Casimir forces are obtained in equilibrium dynamics if the stress tensor is anisotropic.

The Treatment of CISG Article 79 in German Courts: Halting the Homeward Trend
Creators: name: Mazzacano, Peter
Publisher: name: Nordic Journal of Commercial Law
Year: 2012

description: The UN Convention on Contracts for the International Sale of Goods (“CISG”)1 has played a preeminent role in German jurisprudence. This is a fortunate development towards the harmonization of international sales law. This development bucks the “homeward trend” which has plagued a number of signatory states.2 This is a small, but important, step towards a conceptual goal of functional uniformity in a body of international commercial law. As a review of German case law demonstrates, while excuses for non-performance in Article 79 may have developed out of variants of similar domestic legal principles, it ultimately stands alone as an autonomous international doctrine under the CISG. This suggests that the unique development of Article 79 in separate and distinct legal jurisdictions, such as Germany, may ultimately evolve into an autonomous international norm. It further supports the notion that Article 79 is capable of creating relative uniformity within the context of the CISG’s goal for a sales law that is transnational in design.

Improved sampling strategy for representative set construction
Creators: name: Sarkar, Debangsha Kusum
Publisher: name: University of British Columbia
Year: 2022

description: Active learning solves machine learning problems where acquiring labels for the data is costly. A representative subset helps active learning by selecting the most useful subset of a complete data set and querying the labels of the examples present in it. Various sampling strategies exist for the construction of this type of representative subset. However, the state-of-the-art approaches for subset sampling aim to construct a representative subset where the cost of optimization on the subset is comparable to that of the complete data set. They do not attempt to capture the underlying distribution of the data, which we believe is the most important part of representative sampling. This thesis proposes an adaptation of the sigma point sampling (SPS) technique from unscented transformation (UT) for subset sampling. Unscented transformation (UT) has shown to be very effective in non-linear transformation modeling in object tracking and robotics. We show in this thesis that when combined with the Gaussian mixture model, sigma points can estimate the true statistics of an unknown distribution of data with very few samples. The sigma point sampling approach being parameterized gives better control over the sampling process than the non-parameterized sampling techniques. We use the representative subset for active learning on an existing data set. As a practical application of this novel sampling technique, we use it for Active Transfer Learning (ATL) on autoclave processing data to optimize the manufacturing of high-quality aerospace composite parts. The sampling technique is tested on both classification and regression problems in a pool-based active learning scenario. After comparing our approach to the state-of-the-art sampling techniques, We show that sigma point sampling either outperforms or matches their performance. We also test the sensitivity of the parameters in the sigma point sampling. The success of this sampling technique is very significant for future developments of representative sampling on big data sets. The application of our representative subset is not limited to active learning and transfer learning. There is further potential to extend this approach to parallelizing computation on big data sets among multiple clusters.

description: В статье представлена инновационная технология для заготовки фуражного зерна повышенной влажности (от 16 до 40%) и хранение в герметичных условиях. Эта технология обеспечивает уборку зерновых культур в фазу начала восковой спелости или на 7-15 дней раньше уборки в фазу полной спелости, что особенно важно для регионов РФ с неустойчивой погодой. Установлено также, что эффективность скармливания такого корма выше, чем приготовленного из сухого зерна.
description: The article presents an innovative technology for harvesting feed grain with high humidity (from 16 to 40%) and storage in sealed conditions. This technology provides harvesting of grain crops in the phase of the beginning of wax ripeness or 7-15 days before harvesting in the phase of full ripeness, which is especially important for regions of the Russian Federation with unstable weather. It has also been established that the efficiency of feeding such a feed is higher than that prepared from dry grain.
Intellectual Property Licensing for the Purposes of the Technology Transfer Block Exemption Regulation (TTBER)

description: Interaction between technology licensing and EU Competition rules drastically changed seven years ago. Before this change in approach, applying competition law rules to licensing agreements was a relatively simple matter of identifying restrictive provisions of the agreement and proofing them against a block exemption regulation. There was no need to fully understand the competition policy or mechanics of Article 101 TFEU1. It all changed when the Commission decided to modernize its approach, which ended in adoption of Technology Transfer Block Exemption Regulation (TTBER) and extensive guidelines related to licensing agreements. In order to give a full picture on this interaction the paper will examine in detail how and why intellectual property rights [hereinafter IPRs] are being licensed, what kind of licenses exist, and what the key issues in licensing IPRs are. Because the focus is on block exemption regulation and the hardcore restrictions therein, only the four IPRs that the TTBER applies to, will be analyzed. Since the vast majority of scholarship globally that cover the issues related to interaction between competition rules and intellectual property rights licensing, turn immediately to the very core of the problem (hardcore restrictions in the agreement, position of the contracting parties, reduction of dynamic efficiency etc.) there is a need for scholarship that outlines the starting point and assumptions underlying the aforementioned issues and thoroughly guides a less IP-educated reader of such materials into the area with less difficulty. One must keep in mind that the Commission’s concern is aggravated regarding IPRs, due to the fact that they are territorial in their nature (the content of IPRs in one country is determined by the law of that country and effective only within that jurisdiction), which makes their exercise inherently restrictive of the free movement of goods in the internal market. The inherent contradiction between free trade and IPR protection has been recognized globally. The Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPS)2, which is administered by the World Trade Organization, sets forth minimum standards for protection of IPRs for WTO Member States, thus leveling the playground for holders of IPRs and other players on the market.

DISSECTING THE ROLE OF THE CYTOPLASMIC MUTANT NUCLEOPHOSMIN IN ACUTE MYELOID LEUKAEMIA DEVELOPMENT

description: Acute myeloid leukaemia (AML) is a genetic heterogeneous group of diseases, with the largest subgroup showing a mutation in the Nucleophosmin gene (NPM1). Normally the NPM protein localizes mainly in the nucleolus, but in AML blasts it is aberrant localized to the cytoplasm (NPMc+AML). Notably, NPMc+AML patients show peculiar gene expression profiles, treatment response and prognosis. Hence, it has been proposed as an independent category for leukaemia classification according to WHO in 2008. In view of the relevance of NPMc+ mutation to AML pathogenesis and prognosis, understanding its role in leukaemia development represents a major issue in the field. The aim of this PhD project is to get further insight into the relevance of NPMc+ mutations to AML development. To this scope, here it is reported a characterization of a novel mouse model expressing the mutated protein. The hematopoietic restricted expression of the protein induces leukaemia in mice. This data definitively clarify that NPMc+ is an initiating mutation for leukaemia development. However, the long latency and low penetrance of disease onset strongly support the need of cooperating mutations. Since, the high frequency of FLT3-ITD mutations in NPMc+AML, we genetically tested the synergisms between the two abnormalities. To this scope, NPMc+ mice were crossed with FLT3-ITD mice (Lee, 2007). Double mutated mice developed leukaemia with sort latency and full penetrance indicating effective cooperation. Moreover, our data support the two hits model of tumourigenesis, where functional complementary mutations contribute to disease onset. Another major challenge of this project is to understand how NPMc+ affect the biology of normal HSPC and imposes the transition from normal to cancer stem cells. We found that NPMc+ expression perturbs the homeostasis of HSCP and expand the number of LT-HSC by increasing the proliferation rate. However, this enhanced proliferation is not associated to loss of quiescent and functional HSC, which may represent a reservoir of persistent pre-malignant cells available for the accumulation of additional genetic alteration. Further investigation into the biology of per-leukaemic stem cells may give insights into the molecular mechanisms imposed by the oncogene for malignancy transformation and finally may contribute for the development of new therapeutic strategies.
PER UNA CRITICA DEL PRINCIPIO IURA NOVIT CURIA

description: La ricerca affronta il problema del rapporto tra giudice e legge, sotto lo specifico angolo visuale degli ampi poteri che, tradizionalmente, sono riconosciuti al magistrato nella qualificazione giuridica del diritto dedotto dalla parte nel processo. La Prima Sezione dello studio pone in evidenza le complesse interrelazioni che nascono tra la sfera del fatto e quella del diritto oggettivo, nell'inevitabile sforzo di identificare il singolo rapporto giuridico a tutela del quale � richiesto l'intervento giudiziale. Si dimostra, per tal via, l'erroneit� dell'insegnamento tralatizio secondo cui il fatto � cosa delle parti, mentre il diritto � cosa del giudice. L'analisi viene affrontata in modo distinto per tre macrocategorie di rapporti giuridici: la prima, comprensiva di quelli per cui certamente assume rilievo la causa della domanda; la seconda, comprendente quelli per i quali la questione di diritto � centrale rispetto a quello che si domanda; la terza, che riunisce le situazioni giuridiche che danno origine alla tutela c.d. costitutiva. Alla luce dei risultati raggiunti, nella Seconda Sezione s'indaga l'essenza del principio iura novit curia e si prosegue la ricerca col fine di verificare l'effettiva esistenza di un suo fondamento positivo, al di l� delle classiche e ricorrenti affermazioni. Non si rinviene, tuttavia, alcuna disposizione n� alcun principio generale precettivo che sia in grado di giustificare la vigenza della regola tradizionale, espressa nei termini dell'attribuzione al giudice del potere di fondare l'accoglimento sulla base di argomentazioni giuridiche non svolte dalla parte. Inoltre, gli assai negativi riverberi sull'imparzialit� del giudice che importa l'applicazione della regola classica, costituiscono ragione ulteriore per ritenere a tutt'oggi vigente nel nostro ordinamento una regola dal contenuto opposto a quello attribuito al brocardo tradizionale: il giudice ha il potere-dovere di accogliere la domanda giudiziale esclusivamente sulla base delle postulazioni giuridiche svolte dalla parte che ha agito.
Comparative Commercial Law: Methodologies, Black Letter Law and Law-in-Action

description: Evaluating the strengths and weaknesses of international business transactions presents vexing challenges for the legal comparativist and practitioner. Divergent legal regimes impact business decisions, as commercial transactions extending across different legal jurisdictions may produce different and perhaps unexpected results. Exclusively relying on black-letter law does not sufficiently capture the entire comparative landscape. Rather, evaluating how black letter law, or law-in-the-books, reacts with law in practice presents the optimal analytical vantage point.1 Such approach necessitates that a credible, neutral and objective method evaluates the international business transaction — one which considers that economic, cultural and sociological viewpoints, perhaps competing, all exist. These analytical methods, while providing valuable reference points, do not independently present a complete picture.2 Rather, a hybrid comparative theory, objective pluralism, incorporating all of these methodologies, is a more effective evaluator tool providing the optimum means for evaluating comparative commercial law issues.3 The totality of this review presents a balanced perspective offering unique issue insights. Part one introduces the need for objective modes of comparative law analysis within the context of international business transactions, most notably contractual relationships. Discussing the disparate common and civil law families evidences why objective methods are necessary to explore legal problems extending over systematic divergences. Focusing on how good faith under comparative contract law is interpreted quite differently between (and within) these families demonstrates that legal concepts transplanted across legal families may have different meanings. Part two explores how black letter law is applied in practice, through the lens of objective pluralism, yielding nuances while providing comparativists with an important toolkit to further “test” a legal problems. The economic comparative method is evaluated, with special focus given to efficiency and transaction-based economic methodologies. Next, the sociological comparative method is analyzed, with emphasis on behavioral theory. Relational contracting, which contains elements of economic-based methodologies, is subsequently reviewed. The paper then proposes the new methodology, objective pluralism, as the most efficient tool for analyzing the strengths and weaknesses of comparative business transactions. Practical application of objective pluralism involves a carefully-constructed survey or empirical study.

description: Utilizing high-resolution large-scale galaxy formation simulations of the standard cold dark matter model, we examine global trends in the evolution of galaxies due to gravitational shock heating by collapse of large halos and large-scale structure. We find two major global trends. (1) The mean specific star formation rate (sSFR) at a given galaxy mass is a monotonically increasing function with increasing redshift. (2) The mean sSFR at a given redshift is a monotonically increasing function of decreasing galaxy mass that steepens with decreasing redshift. The general dimming trend with time merely reflects the general decline of gas inflow rate with increasing time. The differential evolution of galaxies of different masses with redshift is a result of gravitational shock heating of gas due to formation of large halos (groups and clusters) and large-scale structure that move a progressively larger fraction of galaxies and their satellites into environments where gas has too high an entropy to cool to continue feeding resident galaxies. Overdense regions where larger halos are preferentially located begin to be heated earlier and have higher temperatures than lower density regions at any given time, causing sSFR of larger galaxies to fall below the general dimming trend at higher redshift than less massive galaxies and galaxies with high sSFR to gradually shift to lower density environments at lower redshift. We find that several noted cosmic downsizing phenomena are different manifestations of these general trends. We also find that the great migration of galaxies from blue cloud to red sequence as well as color-density relation, among others, may arise naturally in this picture.
