description: To study the interplay of jamming, cluster formation, and motility-induced phase separation in the zero temperature limit in two dimensions, we consider a simple model system consisting of a bidisperse mixture of disks that are only subject to a repulsion force in case of overlaps and an active force. The orientation of the disks is chosen randomly in the beginning and does not change anytime during the simulation thus corresponding to an infinite persistence length. Simulations with our model system reveal that jammed clusters of particles occur in the dense phase of a phase-separated state in case of intermediate values of the ratio of active to repulsive force. However, for smaller activities there are only a few overlaps between the particles in the dense phase and the coexistence region ends at a packing fraction below the onset of jamming. Finally, for large activities small clusters corresponding to small patches of the dense phase are found that are unstable due to the activity. Our findings on how jamming and phase separation are related are relevant to many active particle systems whose zero temperature and long persistence limits correspond to our model system.

title: Assessing Stress Tolerance of Organelle Small Heat Shock Protein Mutants in Arabidopsis Thaliana
Creators: name: Patel, Parth
Publisher: name: University of Massachusetts Amherst

description: Molecular chaperones are proteins found in virtually every organism and are essential to cell survival. When plants are heat stressed, they upregulate and downregulate multiple genes, many of which are associated with the heat shock response. Small heat shock proteins (sHSPs) are one class of molecular chaperones that are upregulated during heat shock. They are proposed to act as the first line of defense by binding to heat sensitive proteins and preventing their irreversible aggregation. However, many details of sHSP function remain to be discovered and exactly what proteins they protect is unresolved. In addition to cytosolic sHSPs found in other organisms, plants also produce sHSPs that are targeted to organelles. In this study, I focus on the mitochondria and chloroplast localizing sHSPs: HSP23.5-MTI/CP, HSP23.6-MTI/CP, HSP25.3-CP, and HSP26.5-MTII in Arabidopsis thaliana. The heat tolerance of knockout mutants of these different organelle-localized sHSPs, including single, double, triple, and quadruple knockouts was assessed through various stress assays. A hypocotyl elongation assay indicated a mild heat sensitive phenotype for many of the sHSP knockout mutants and plants lacking all four sHSPs showed the greatest reduction in hypocotyl elongation following heat stress. In an vi assay with light grown seedlings, I observed plants that lacked the chloroplast-localizing HSP25.3-CP were sensitive to acute heat stress. In stress assays involving arsenic, plants that did not express mitochondrial sHSPs were the most sensitive to excess arsenic. Interestingly, plants lacking the four sHSPs were more resistant to salt and cadmium stress. The phenotypes of these sHSPs will bring us closer to defining their mechanism of action during heat or heavy metal stress and the mutants will provide a platform for further studies of sHSP structure and function.
Brahms and Schubring: Musical Criticism and Politics at Mid-Century
Creators: name: Frisch, Walter M.
Publisher: name: Columbia University
Year: 1984
Subjects: Music

description: Comprising the first substantial critical account of Brahms's music, Adolf Schubring's essay, published in 1862, is especially valuable for having appeared so early in the composer's career, on the verge of his thirtieth year and the period Tovey called his "first maturity." Schubring makes a fine witness to the early Brahms because, unlike Tovey and the rest of us, he had no knowledge of the composer's later development. And although basically sympathetic, he pulls no punches. Much of the music comes in for strong -- and impressively perceptive -- criticism. Interesting in its own right, Schubring's article also opens a broader perspective on the highly "politicized" German musical scene at mid-century, in which the Rezeptionsgeschichte of the young Brahms plays an important role.

Reger's Bach and Historicist Modernism
Creators: name: Frisch, Walter M.
Publisher: name: Columbia University
Year: 2001
Subjects: Music

description: Max Reger forged a special path to musical modernism, one that may be considered historicist, through his assimilation of the music of J. S. Bach. Historicism acknowledges a debt to tradition and the past, but through the perspective and techniques of the present. Brahms proved a powerful model for Reger's historicist modernism. The article first briefly examines Bach reception in the Austro-German sphere in the years around 1900 and Reger's own activities as editor, arranger, and performer of Bach's music. It then focuses on two of Reger's own compositions. An early work, the Organ Suite, op. 16 (1895), has as its slow movement a chorale prelude based on three different melodies associated with Bach, which are combined in dense counterpoint. The E-minor finale of op. 16 is an extraordinary synthesis of Bach's C-Minor Passacaglia and the last movement of Brahms's Fourth Symphony. In a mature work, the Variations and Fugue on a Theme of Bach, op. 81 (1904), for piano, Reger self-consciously places himself in the tradition of two monumental variation sets from the nineteenth century, Beethoven's "Diabelli" and Brahms's Handel Variations. Reger creates a complex temporal-historical framework in which Bach's theme and the stricter variations that adhere to its structure seem to imply a more stable past while the freer, more fragmentary, and improvisatory-sounding variations capture an anxious present. This tension between past and present lies at the heart of Reger's historicist modernism.
Post-dynamical inspiral phase of common envelope evolution: Binary orbit evolution and angular momentum transport

description: After the companion dynamically plunges through the primary's envelope, the two cores remain surrounded by a common envelope and the decrease of the orbital period $P_\text{orb}$ stalls. The subsequent evolution has never been systematically explored with multidimensional simulations. For this study, we performed 3D hydrodynamical simulations of an envelope evolving under the influence of a central binary star using an adaptively refined spherical grid. We followed the evolution over hundreds of orbits of the central binary to characterize the transport of angular momentum by advection, gravitational torques, turbulence, and viscosity. We find that local advective torques from the mean flow and Reynolds stresses associated with the turbulent flow dominate the angular momentum transport, which occurs outward in a disk-like structure about the orbital plane and inward along the polar axis. Turbulent transport is less efficient, but can locally significantly damp or enhance the net angular momentum radial transport and may even reverse its direction. Short-term variability in the envelope is remarkably similar to circumbinary disks, including the formation and destruction of lump-like overdensities, which enhance mass accretion and contribute to the outward transport of eccentricity generated in the vicinity of the binary. If the accretion onto the binary is allowed, the orbital decay timescale settles to a nearly constant value $τ_\text{b} \sim 10^3$ to $10^4\,P_\text{orb}$, while preventing accretion leads to a slowly increasing $τ_\text{b} \sim 10^5\,P_\text{orb}$ at the end of our simulations. Our results suggest that the post-dynamical orbital contraction and envelope ejection will slowly continue while the binary is surrounded by gas and that $τ_\text{b}$ is often much shorter than the thermal timescale of the envelope.

description: In the late 1950s, broadcasters waged war on a new, disruptive technology that threatened to change the television industry forever: cable. Broadcasters and their allies attempted to stifle cable by exercising their intellectual property rights, calling cable a “huge parasite in the marketplace” and attacking it for exploiting the works of others. Today, broadcasters face a new technology threatening to disrupt the television landscape: services disseminating television programming via the Internet. Just as they did in the 1950s, broadcasters have launched a legal battle against these services, characterizing them as exploitative—the modern parasites in the marketplace. Aereo, a service that captures over-the-air television and transmits it via the Internet to paying subscribers, is at the center of this dispute. Echoing the early cries that cable would “prove more revolutionary than the printing press," Aereo has been heralded as a victory for innovation and consumer choice in an otherwise archaic television industry, turning laptops and smartphones into television sets and leaving behind the days of a “giant rooftop antenna or awkward rabbit ears.” Aereo is able to provide consumers with an alternative to set-top boxes, expensive contracts and bundled plans, while keeping prices at a modest $8 per month by not paying licensing or retransmission fees to broadcasters.

description: Test functions are important to validate and compare the performance of optimization algorithms. There have been many test or benchmark functions reported in the literature; however, there is no standard list or set of benchmark functions. Ideally, test functions should have diverse properties so that can be truly useful to test new algorithms in an unbiased way. For this purpose, we have reviewed and compiled a rich set of 175 benchmark functions for unconstrained optimization problems with diverse properties in terms of modality, separability, and valley landscape. This is by far the most complete set of functions so far in the literature, and tt can be expected this complete set of functions can be used for validation of new optimization in the future.

title: Short Term Energy Forecasting for a Microgird Load using LSTM RNN
Creators: name: Soman, Akhil
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Decentralization of the electric grid can increase resiliency (during natural disasters) and can reduce T&D energy losses and emissions. Microgrids and DERs can enable this to happen. It is important to optimally control microgrids and DERs to extract the greatest economic, environmental and resiliency benefits. This is enabled by robust forecasting to optimally control loads and energy sources. An integral part of microgrid control is power side and load side demand forecasting.
In this thesis, we look at the ability of a powerful neural network algorithm to forecast the load side demand for a microgrid using the UMass campus as the test bed. UMass has its own power plant producing 16 MW of power. In addition to this, Solar panels totaling 5.5MW and lithium ion battery bank of 1.32 MW/4 MWh are also available. An LSTM recurrent neural network is used for demand forecasting. In addition to a fully trained LSTM network, multi linear regression model, ARIMA and ANN model are also tested to compare the performance.
In addition to the Short Term Load Forecasting, the peak prediction accuracy of the model was also tested to run a battery discharge algorithm to shave peak demand for the microgrid. This will result in demand cost savings for the facility. Finally, the fully trained neural network was deployed on a raspberry pi computer.

description: Répétition d’un Ballet, the famous painting by French artist Edgar Degas, sold for $401,000 in 1965. The jubilant seller bragged that Degas originally asked a mere $100 for the painting. In his early career, celebrated American artist Norman Rockwell sold original works like Homecoming Marine and Breaking Home Ties for a few hundred dollars each. In the last decade, these paintings were resold for $9.2 million and $15.4 million at Sotheby’s auctions, but the Rockwell estate received nothing in these transactions. Over the centuries, great wealth in the arts has rarely translated into great wealth for the artist. Since its inception in France, the resale royalty known as the droit de suite has aimed at remedying this perceived injustice. Although a resale royalty right is currently recognized in seventy-nine jurisdictions, California is the only American jurisdiction to have adopted it. The California Resale Royalties Act (CRRA), enacted in 1976, grants visual artists the right to collect a 5% royalty on the total sales price each time their works are resold in California or by a resident of California. The fate of the California Resale Royalty Act, however, currently rests with the U.S. Court of Appeals for the Ninth Circuit.

description: The typical complaint about intellectual property laws is that they are sluggish in responding to technological change. An unfolding question in the contemporary era, however, is the degree to which the threat of constitutional challenge will lead Congress to further adhere to the status quo. In the wake of the patent law overhaul several years ago, for example, the wisdom and scope of those amendments were widely debated, but concern about their constitutional soundness was also expressed in some quarters. Likewise, the latter concern is in play with respect to a proposed amendment of the law that applies to sound recordings. Amidst the waves of technological innovation affecting access to music, the eyes and ears of the music industry, library associations, policy makers and others are focused on a legislative decision made some four decades ago. Specifically, these parties are staking out their positions on the possibility of extending federal copyright protection to pre-1972 sound recordings. Those sound recordings are currently protected through 2067 by a patchwork of state laws, and after that date all pre-1972 sound recordings will enter the public domain. The U.S. Copyright Office has issued a report recommending that pre-1972 sound recordings be brought under federal copyright protection in the near future. There are sound reasons for doing so. The Office’s proposal would result in a shorter term of protection for some recordings and effect other changes in the rights and responsibilities of right holders and users.
Blazhko effect in Cepheids and RR Lyrae stars

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: The Blazhko effect is the conspicuous amplitude and phase modulation of the pulsation of RR Lyrae stars that was discovered in the early 20th century. The field of study of this mysterious modulation has recently been invigorated thanks to the space photometric missions providing long, uninterrupted, ultra-precise time series data. In this paper I give a brief overview of the new observational findings related to the Blazhko effect, like extreme modulations, irregular modulation cycles and additional periodicities. I argue that these findings together with dedicated ground-based efforts now provide us with a fairly complete picture and a good starting point to theoretical investigations. Indeed, new, unpredicted dynamical phenomena have been discovered in Blazhko RR Lyrae stars, such as period doubling, high-order resonances, three-mode pulsation and low-dimensional chaos. These led to the proposal of a new explanation to this century-old enigma, namely a high-order resonance between radial modes. Along these lines I present the latest efforts and advances from the theoretical point of view. Lastly, amplitude variations in Cepheids are discussed.

Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: Some issues which are relevant for the recent state in climate modeling have been considered. A detailed overview of literature related to this subject is given. The concept in modeling of climate, as a complex system, seen through Godel's Theorem and Rosen's definition of complexity and predictability is discussed. It is pointed out to occurrence of chaos in computing the environmental interface temperature from the energy balance equation given in a difference form. A coupled system of equations, often used in climate models is analyzed. It is shown that the Lyapunov exponent mostly has positive values allowing presence of chaos in this systems. The horizontal energy exchange between environmental interfaces, which is described by the dynamics of driven coupled oscillators, is analyzed. Their behavior and synchronization, when a perturbation is introduced in the system, as a function of the coupling parameters, the logistic parameter and the parameter of exchange, was studied calculating the Lyapunov exponent under simulations with the closed contour of N=100 environmental interfaces. Finally, we have explored possible differences in complexities of two global and two regional climate models using their output time series by applying the algorithm for calculating the Kolmogorov complexity.

description: Fermi liquid theory is the basic paradigm within which we understand the normal behavior of interacting electron systems, but quantitative values for the parameters that occur in this theory are currently unknown in many important cases. One such case is the two-dimensional homogeneous electron gas (2D HEG), which is realized in a wide variety of semiconductor devices. We have used quantum Monte Carlo (QMC) methods to calculate the Landau interaction functions between pairs of quasiparticles. We use these to study the Fermi liquid parameters, finding that finite-size effects represent a serious obstacle to the direct determination of Fermi liquid parameters in QMC calculations. We have used QMC data in the literature for other properties of the 2D HEG to assemble a set of "best available" values for the Fermi liquid parameters.

The proposed relation extends the static case, yields the Laplace formula in cases of mass transfer across interfacial layers and allows to take the second coefficient of viscosity of compressible fluids into account. We generalize the Maxwell rule in dynamics and directly explain the Marangoni effect.

description: A near-field integrated sensing and communications (ISAC) framework is proposed, which introduces an additional distance dimension for both sensing and communications compared to the conventional far-field system. In particular, the Cramer-Rao bound for the near-field joint distance and angle sensing is derived, which is minimized subject to the minimum communication rate requirement of each user. Both fully digital antennas and hybrid digital and analog antennas are investigated. For fully digital antennas, a globally optimal solution of the ISAC waveform is obtained via semidefinite relaxation. For hybrid antennas, a high-quality solution is obtained through two-stage optimization. Numerical results demonstrate the performance gain introduced by the additional distance dimension of the near-field ISAC over the far-field ISAC.

description: Recent judicial interpretations of U.S. copyright law have prompted businesses to design technologies in ways that enable the making and transmission of copies of works to consumers while falling outside the scope of the owner’s exclusive rights. The archetypal example was Aereo, Inc.’s system for providing online access to broadcast television. Aereo allowed users to tune into individual antennae to stream near-live TV to themselves, online. If this activity fell within the scope of the exclusive right of public performance, then it required the permission of right holders. The “Transmit Clause” of the U.S. Copyright Act’s definition of “to perform publicly” brings within the scope of the public performance right: [T]ransmitting or otherwise communicating a performance or display of the work . . . to the public, by means of any device or process, whether the members of the public capable of receiving the performance or display receive it in the same place or in separate places and at the same time or at different times. Holdings from the Second Circuit that the relevant performance was the specific transmission from each copy, and that those performances could not be public if made to only a single user, gave Aereo a blueprint for avoiding liability. It took up the invitation by designing a system incorporating thousands of dime-sized antennas. By temporarily assigning one to each user, from which she could access only the signals she could freely pick up from her own rooftop, Aereo’s service enabled individual copies to be made of each program and then transmitted on request to the user. Since each transmission was directed only to the single requesting user, Aereo argued it could not be considered made “to the public.”

description: Anatomical abnormalities in the thoracic outlet syndrome are very frequent, but radiological images are not always reliable. Therefore, the different features and abilities of CT angiogram and brachial plexus MRI to detect anatomical abnormalities have been investigated. All radiological and surgical records of patients operated for thoracic outlet syndrome between January 2011 and December 2018 were retrospectively analyzed. Considering the CT angiogram and/or brachial plexus MRI reports of the preoperative period, the performance of these investigations was evaluated by calculating the precision (P), sensitivity (Recall) and Hamming loss (L). From a total of 107 patients screened, 84 were eligible for study inclusion. Out of these, 46 had surgical abnormalities (group 1), while 38 did not (group 2). Among them, 30 patients have performed CT angiogram (subgroup A), 32 brachial plexus MRI (subgroup B) and 22 both (subgroup C). The best result is obtained when both diagnostic examinations are performed (subgroup C: P = 0.62; recall = 0.52; L = 0.038). Prescribing both investigations in selected patients increases the probability of finding anatomic anomalies and facilitates preoperative planning. However, as the radiological images are not completely exhaustive, the surgeon should always actively search and remove any potential source of compression on the nervous vascular bundle along the thoracic outlet.

description: In Erklärungen zu data sharing in den data policies von Zeitschriften wird empfohlen bzw. vorgeschrieben, dass Daten, die die Grundlage des Artikels bilden, zur Verfügung gestellt werden. Data policies sind dabei neben der notwendigen technischen Infrastruktur und nicht-technischen Aspekten wie einer positiven persönlichen Einstellung von Wissenschaftler*innen entscheidende Instrumente, um data sharing zum Zwecke der wissenschaftlichen Transparenz und Nachnutzung der Daten zu fördern. Die best practice für die Veröffentlichung von Daten wurde inzwischen für viele Fachdisziplinen beschrieben. Eine häufige Forderung in diesen Empfehlungen ist, dass alle zentralen Forschungsergebnisse in Repositorien publiziert werden, die sich an den FAIR-Prinzipien orientieren. Das bedeutet auch, dass „supplementary electronic material“ auf den Webseiten der Zeitschriftenverlage nicht mehr als primäres Datenarchiv verwendet werden soll. Zeitschriften sollten umfassende, klare und aktuelle Informationen bereitstellen, die allgemeine Grundsätze für die Nachnutzung von Daten sowie die Einzelheiten dessen beschreiben, was von den Autoren in Bezug auf die Bereitstellung von Forschungsdaten erwartet wird. Im ersten Teil der Präsentation werden die wichtigsten Komponenten einer aktuellen journal data policy vor dem Hintergrund neuer Erkenntnisse zu diesem Thema diskutiert. Fachgesellschaften sowie Einrichtungen geben häufig wissenschaftliche Zeitschriften heraus, und als "Eigentümer" der Zeitschriften haben sie die Kontrolle über die Existenz und den Inhalt der data policies der Zeitschriften. Im zweiten Teil der Präsentation wird beschrieben, wie innerhalb weniger Monate im Sommer 2020 eine data policy für die Zeitschrift „Hydrologie und Wasserbewirtschaftung, HyWa“ eingeführt wurde. Die Zeitschrift HyWa ist eine deutschsprachige Fachzeitschrift, herausgegeben durch die gewässerkundlichen Fachverwaltungen des Bundes und der Länder, die Themen der Hydrologie und Wasserwirtschaft umfassend behandeln. Im Sommer 2020 erreichten die HyWa-Redaktion Anfragen seitens universitärer Einrichtungen zur Möglichkeit für Online-Datenanhänge zu einem geplanten Artikel. Um diesem neuen Sachverhalt, der Publizierung von Artikeln mit Fachdaten nachzukommen, wurde unter Abstimmung mit dem HyWa- Redaktionsausschuss und Inkenntnissetzung der HyWa-Editoren mit Unterstützung des Fachinformationsdienstes Geowissenschaften (FID GEO) im August 2020 eine Data Policy erstellt und auf der HyWa-Homepage publiziert (www.hywa-online.de). Die Analyse der Online-Zugriffe auf die neu eingerichtete Webseite zeigt, dass sie stetig wahrgenommen wird.

description: The low surface brightness disc galaxy Malin2 challenges the standard theory of galaxy evolution by its enormous total mass ~2 10^12 Ms which must have been formed without recent major merger events. The aim of our work is to create a coherent picture of this exotic object by using the new optical multicolor photometric and spectroscopic observations at Apache Point Observatory as well as archival datasets from Gemini and wide-field surveys. We performed the Malin2 mass modelling, estimated the contribution of the host dark halo and found that it had acquired its low central density and the huge isothermal sphere core radius before the disc subsystem was formed. Our spectroscopic data analysis reveals complex kinematics of stars and gas in the very inner region. We measured the oxygen abundance in several clumps and concluded that the gas metallicity decreases from the solar value in the centre to a half of that at 20-30 kpc. We found a small satellite and measured its mass (1/500 of the host galaxy) and gas metallicity. One of the unique properties of Malin2 turned to be the apparent imbalance of ISM: the molecular gas is in excess with respect to the atomic gas for given values of the gas equilibrium turbulent pressure. We explain this imbalance by the presence of a significant portion of the dark gas not observable in CO and the Hi 21 cm lines. We also show that the depletion time of the observed molecular gas traced by CO is nearly the same as in normal galaxies. Our modelling of the UV-to-optical spectral energy distribution favours the exponentially declined SFH over a single-burst scenario. We argue that the massive and rarefied dark halo which had formed before the disc component well describes all the observed properties of Malin2 and there is no need to assume additional catastrophic scenarios proposed previously to explain the origin of giant LSB galaxies.

description: The CHIRON optical high-resolution echelle spectrometer was commissioned at the 1.5m telescope at CTIO in 2011. The instrument was designed for high throughput and stability, with the goal of monitoring radial velocities of bright stars with high precision and high cadence for the discovery of low-mass exoplanets. Spectral resolution of R=79,000 is attained when using a slicer with a total (including telescope and detector) efficiency of 6% or higher, while a resolution of R=136,000 is available for bright stars. A fixed spectral range of 415 to 880 nm is covered. The echelle grating is housed in a vacuum enclosure and the instrument temperature is stabilized to +-0.2deg. Stable illumination is provided by an octagonal multimode fiber with excellent light-scrambling properties. An iodine cell is used for wavelength calibration. We describe the main optics, fiber feed, detector, exposure-meter, and other aspects of the instrument, as well as the observing procedure and data reduction.

title: Nozzle Clogging Prevention and Analysis in Cold Spray
Creators: name: Foelsche, Alden
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Cold spray is an additive manufacturing method in which powder particles are accelerated through a supersonic nozzle and impinged upon a nearby substrate, provided they reach their so-called critical velocity. True to its name, the cold spray process employs lower particle temperatures than other thermal spray processes while the particle velocities are comparably high. Because bonding occurs mostly in the solid state and at high speeds, cold spray deposits are distinguished for having low porosity and low residual stresses which nearly match those of the bulk material.
One complication with the cold spray process is the tendency for nozzles to clog when spraying (in general) low-melting-point or dense metal powders. Clogging occurs when particles collide with the inner nozzle wall and bond to it rather than bouncing off and continuing downstream towards the substrate. The particles accumulate and eventually plug the nozzle passage. Clogging is inconvenient because it interrupts the spraying process, making it impossible to complete a task. Furthermore, when particle buildup occurs inside the nozzle, the working cross-sectional area decreases, which decreases the flow velocity and therefore the particle velocity, ultimately jeopardizing the particles’ ability to reach critical velocity at the substrate.
In this work, computational fluid dynamics (CFD) is used to study various aspects of nozzle clogging. Nozzle cooling with supercritical CO2 as the refrigerant is investigated as a means to prevent clogging. The effects of nozzle cooling on both the driving gas and the particles are addressed. Simplified pressure oscillations at the nozzle inlet are imposed to determine whether such oscillations, if present, can cause clogging. Subsequently, more realistic and complicated flow oscillations are introduced to isolate a potential root cause of clogging. Finally, several novel nozzle internal geometries are evaluated for their effectiveness at preventing clogging. A recommendation is provided for a nozzle to be tested experimentally because it might completely prevent clogging.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.
A Mask that Eats into the Face: Images and the Right of Publicity

description: In their eagerness to reward celebrities for the power of their “images,” and to prevent other people from exploiting those images, courts have allowed the right of publicity to distort the First Amendment. The power of the visual image has allowed courts to create an inconsistent, overly expansive regime that would be easily understood as constitutionally unacceptable were the same rules applied to written words as are applied to drawings and video games. The intersection of a conceptually unbounded right with a category of objects that courts do not handle well has created deep inconsistencies and biases in the treatment of visual and audiovisual media, particularly comics and video games. These problems show up both in First Amendment defenses and in copyright preemption analysis. The possible arguments one might offer for treating images differently are insufficient to justify this disparity. The Article concludes that, absent the distortion produced by images, the right of publicity would properly be understood as sharply limited.
