description: We consider a harmonically trapped dilute $N$-boson system described by a low-energy Hamiltonian with pairwise interactions. We determine the condensate fraction, defined in terms of the largest occupation number, of the weakly-interacting $N$-boson system ($N \ge 2$) by employing a perturbative treatment within the framework of second quantization. The one-body density matrix and the corresponding occupation numbers are compared with those obtained by solving the two-body problem with zero-range interactions exactly. Our expressions are also compared with high precision {\em{ab initio}} calculations for Bose gases with $N=2-4$ that interact through finite-range two-body model potentials. Non-universal corrections are identified to enter at subleading order, confirming that different low-energy Hamiltonians, constructed to yield the same energy, may yield different occupation numbers. Lastly, we consider the strongly-interacting three-boson system under spherically symmetric harmonic confinement and determine its occupation numbers as a function of the three-body "Efimov parameter".

title: Pacific salmon and farmed salmon on the Pacific coast of Canada

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.The relationship between Pacific salmon (Oncorhynchus spp.) and farmed Atlantic salmon (Salmo salar) remains as one of the most contentious issues in the history of the management of Pacific salmon in British Columbia. The issue is fuelled by a decrease in the commercial catch of Pacific salmon and escalating production of farmed salmon. In 2008, for example, the annual production of farmed salmon was about ten times larger than the commercial catch of Pacific salmon (Figure 1). Salmon farming is controversial for scientific reasons and in some cases for ideological reasons. In British Columbia, one major concern is the effect that sea lice produced on farmed salmon have on wild Pacific salmon. British Columbians use the health of Pacific salmon as a measure of their quality of life. Anything that threatens Pacific salmon makes many people uncomfortable. Thus, in 2002, when there was an unexpected poor return of pink salmon (O. gorbuscha) in an area of intensive fish farming, the issues relating to salmon farming became a public concern

description: We argue that the root cause behind the recent corporate scandals associated with CEO pay is the technology bubble of the latter half of the 1990s. Far from rejecting the optimal incentive contracting theory of executive compensation, the recent evidence on executive pay can be reconciled with classical agency theory once one expands the framework to allow for speculative stock markets.

description: In March 2017, the Fondazione Corrente in Milan hosted a round of "Esthetic Conversations" every Wednesday, organized by Roberto Diodato, Elio Franzini, Fulvio Papi and Gabriele Scaramuzza. The cycle ended with a meeting held by Gabriele Scaramuzza and Sabrina Peron, titled The Remains of God, during which the theme of God's existence in the world of culture was tackled, starting from the reflection of the unthinkability of this World without cathedrals, prayer, religious practices, and treatises of theology. Moving from the philosophy of Banfi's religion, confrontation has widened to broader reflections that included Dostoevsky, Mann, Bulgakov and Yourcenar, and the eternal conflict between good and evil. This work is my report to the conference, while Gabriele Scaramuzza's presentation is being published in Filosofia e Teologia.

description: The transversal propagation of the edge states in a two-dimensional quantum spin Hall system are classified by decay characteristic quantity $λ$. Two different modes of the helical edge states exhibit distinct behaviors. The penetration depth is momentum dependent in normal edge states. The finite size gap decays monotonously with sample width, leading to the normal size effect. In contrast, the penetration depth maintains a uniform minimal value in the special edge states with much shorter length. The finite size gap decays non-monotonously with width, leading to the anomalous finite size effect. Real materials are compared in the phase diagram, which explicitly demonstrates their differences. We also propose an intuitive way to search the special edge states in two-dimensional quantum spin Hall system.

description: The concentration and composition of bioavailable nitrogen (N) and phosphorus (P) in the upper ocean shape eukaryotic phytoplankton communities and influence their physiological responses. Phytoplankton are known to exhibit similar physiological responses to limiting N and P conditions such as decreased growth rates, chlorosis, and increased assimilation of N and P. Are these responses similar at the molecular level across multiple species? To interrogate this question, five species from biogeochemically important, bloom-forming taxa (Bacillariophyta, Dinophyta, and Haptophyta) were grown under similar low N, low P, and replete nutrient conditions to identify transcriptional patterns and associated changes in biochemical pools related to N and P stress. Metabolic profiles, revealed through the transcriptomes of these taxa, clustered together based on species rather than nutrient stressor, suggesting that the global metabolic response to nutrient stresses was largely, but not exclusively, species-specific. Nutrient stress led to few transcriptional changes in the two dinoflagellates, consistent with other research. An orthologous group analysis examined functionally conserved (i.e., similarly changed) responses to nutrient stress and therefore focused on the diatom and haptophytes. Most conserved ortholog changes were specific to a single nutrient treatment, but a small number of orthologs were similarly changed under both N and P stress in 2 or more species. Many of these orthologs were related to photosynthesis and may represent generalized stress responses. A greater number of orthologs were conserved across more than one species under low P compared to low N. Screening the conserved orthologs for functions related to N and P metabolism revealed increased relative abundance of orthologs for nitrate, nitrite, ammonium, and amino acid transporters under N stress, and increased relative abundance of orthologs related to acquisition of inorganic and organic P substrates under P stress. Although the global transcriptional responses were dominated by species-specific changes, the analysis of conserved responses revealed functional similarities in resource acquisition pathways among different phytoplankton taxa. This overlap in nutrient stress responses observed among species may be useful for tracking the physiological ecology of phytoplankton field populations.

description: So why do movie studios care about the right of publicity? The answer is quite simple. Our studios make lots of movies and television programs about and inspired by real people and events. It is critical to our studios that they have the right to do that—whether or not the subjects of those movies and television shows want movies or television shows made about them. To illustrate how important this issue is to our studios in present day, let me say a couple things. The word “copyright” is included in my job title. I am mostly a copyright lawyer, and I think that is why I was hired at the Motion Picture Association. But over the last two to three years, I have spent the majority of my time on right of publicity, more so than on issues involving copyright. My counterparts—the intellectual property lawyers in-house at the movie studios— consider court decisions threatening their right to make movies and television shows about and inspired by real people and events, without obtaining the subjects’ permission, “existential threats.” One of the things that Professor Jennifer Rothman mentioned in her remarks is that we need to do a better job articulating what the nature of this threat is, or what it means as a practical matter. Let me take up the baton and try to give you a sense of just how fundamentally important this issue is in current years.

SMARTINI3 parametrization of multi-scale membrane models via unsupervised learning methods

Publisher: name: TU Dortmund
Year: 2024
Subjects: subject: 530

description: In this study, we utilize genetic algorithms to develop a realistic implicit solvent ultra-coarse-grained (ultra-CG) membrane model comprising only three interaction sites. The key philosophy of the ultra-CG membrane model SMARTINI3 is its compatibility with realistic membrane proteins, for example, modeled within the Martini coarse-grained (CG) model, as well as with the widely used GROMACS software for molecular simulations. Our objective is to parameterize this ultra-CG model to accurately reproduce the experimentally observed structural and thermodynamic properties of Phosphatidylcholine (PC) membranes in real units, including properties such as area per lipid, area compressibility, bending modulus, line tension, phase transition temperature, density profile, and radial distribution function. In our example, we specifically focus on the properties of a POPC membrane, although the developed membrane model could be perceived as a generic model of lipid membranes. To optimize the performance of the model (the fitness), we conduct a series of evolutionary runs with diverse random initial population sizes (ranging from 96 to 384). We demonstrate that the ultra-CG membrane model we developed exhibits authentic lipid membrane behaviors, including self-assembly into bilayers, vesicle formation, membrane fusion, and gel phase formation. Moreover, we demonstrate compatibility with the Martini coarse-grained model by successfully reproducing the behavior of a transmembrane domain embedded within a lipid bilayer. This facilitates the simulation of realistic membrane proteins within an ultra-CG bilayer membrane, enhancing the accuracy and applicability of our model in biophysical studies.

description: This article reflects on an ambivalence in our relationship with the Word of God. On the one hand, it seems present and active, for a civilization that has put at its center the linguistic manifestation of the divine. On the other hand, the evidence that God is silent, and therefore silence must be regarded as the center of this problematic theophany. Our civilization seems to oscillate between the possibility that the logos is the absolute manifestation of the divine, and the possibility that the logos must be transcended to draw on a more subtler language. In the era of “epilogy”, which is the proper name for the decline of a civilization founded on the logos, it is perhaps given to music the task of transmitting the Meaning.

New historical records and relationships among ¹⁴C production rates, abundance and color of low latitude auroras and sunspot abundance

description: Incursions of high-energy particles from space, specifically solar energetic particles and galactic cosmic rays, have significant effects on the Earth, including disruption of the Earth’s magnetic field, generation of electric fields strong enough to damage electronic devices as well as the production of auroras at low-latitudes, within 45° of the magnetic equator. We examine the relationships among ¹⁴C production, auroral abundance, auroral color and sunspot abundance using existing data supplemented by a new dataset. The new dataset, based on Chinese and Korean records from A.D. 1100–1700, includes 46 new or revised records of sunspots and 279 records of low-latitude auroras. Low-latitude auroras are predominantly red (66%, 835 events) with lesser proportions of white (20%, 253 events) and black auroras (6%, 67 events). All other auroral colors (green, yellow, multicolored, blue and purple) aggregate to a total of 100 events (8%). Overall, white auroras are more frequent during times of higher ¹⁴C production. We use two empirical methods of evaluating the flux of high-energy particles: modeled peaks and lows in 14C production and peaks and lows in the ¹⁴C calibration curve. We find that comparison to modeled ¹⁴C production gives significant results. White auroras are significantly more abundant (98% probability) at times of high production of ¹⁴C. Red auroras are somewhat more abundant (88% probability) at times of low production of ¹⁴C. The abundances of black, multicolored, green, yellow, and blue auroras between times of low and high ¹⁴C production are not significantly different. Violet/purple auroras are significantly more abundant (98% probability) at times of low ¹⁴C production. The positive correlation of violet/purple auroras with times of low ¹⁴C production rate and the lack of correlation of blue auroras with times of high ¹⁴C production is surprising, for this portion of the visible spectrum contains strong emission lines and some lines with high energies of excitation. Observations of emissions in the blue to violet part of the spectrum may be biased towards time periods when the atmosphere is exceptionally clear, as these colors are more difficult for the human eye to perceive.

The single-mode case provides a few-parameter description of a novel class of periodic systems, predicting that the ground state of certain four-state atom-cavity systems will undergo parity change at strong coupling. A group-theoretical treatment provides physical insight into dynamics and a modified rotating wave approximation obtains accurate analytical energies. The dissipative case can be applied to study excitation energy transfer in molecular rings or chains.

description: I have written exactly one paper about the right of publicity. It was in 2004. So this was a good chance to start thinking hard again about things I have not thought about in a while. That paper was the first paper I ever wrote as an academic. I reread it last week, and it felt a lot like the first paper I ever wrote as an academic. I do not advise that, by the way. It is not a good feeling. What I was most struck by in reading that paper is that nothing has changed in the time since I wrote it in terms of what the big issues are. I say this having reread Mark and Stacey’s piece as well, which is about the same time period. What those papers were trying to do was to think about what the right of publicity is, what it should be about, whether it has a real conceptual core to it, and what would follow from that in terms of the structure of the right. This is the way academics tend to think: What is the right about, and then—on this naïve assumption that you might be able to deduce from the theory what the actual practice should be—whether the scope of the right is tethered to the right’s justification. If you can work out the right at a conceptual level, then all the doctrinal limits would follow from that. Many people during that era offered ways of thinking about the right that would have justified a right of some scope—probably a more limited scope than some folks on this panel might want, but a right nonetheless. I think it is a more difficult question to figure out whether that right would be meaningfully different from what is protected under Section 43(a) type claims of false endorsement. If you approach the issue, not from the perspective of theory, but from the doctrine itself, I do not think any fair-minded person could look at the right of publicity as it actually exists and believe that the doctrine derived from a coherent theory. It has characteristics of both personal and property rights. It resembles in different ways and at different times privacy and IP rights. But the mixture is hard to explain in any satisfactory way. Jennifer Rothman referred to it as having an identity crisis. I think that was probably generous. I think the fact is that is what really animated all the papers I was talking about: This sort of weird mixture of different things that make it hard to identify any particular coherent theory.

description: This paper examines some of the Anti-Trinitarian interpretations on God's words.It starts from the expulsion from the Garden of Eden, seen according to a Hebrew commentary, the one of Erich From,up to some heretics of 1500 who challenged the Trinity, according to a philological reading of the Scriptures, cleared of some of the encrustations due to the tradition. The paper deals with Serveto, Biandrata, and Ferenc David, but mentions also the survival of some of the Anti-Trinitarian theses in the philosophy of Ralph W. Emerson, a philosopher who had a not negligible weight in the development of the American culture of the nineteenth century. One of the last heirs of this tradition is the Jesuit Roger Lenaers, who considers it appropriate to refer to the Anti- trinitarian ideas, to give new life to the living word of God, in a world that he considers desecrated. Beyond the utopias, however, we should not forget the violent aspects that have always been linked to the word of God, of which we have seen some examples here.

description: Chevrons are elongated dunes with a V-shaped pattern in map view. In some exposures, smaller Vs are nested within the larger Vs. The term chevron was first used to describe desert dunes (Maxwell and Haynes, 1989) based on their similarity to the nested chevrons used on military uniforms or in heraldry. Chevrons later were identified in coastal regions and proposed to represent megastorm deposits (Hearty et al., 1998; Kindler and Strasser, 2000). Subsequently, other workers suggested that some coastal chevron dunes were tsunami deposits (Bryant and Nott, 2001; Scheffers and Kelletat, 2003; Scheffers et al., 2008). The proposal that some coastal chevron dune complexes represent tsunami deposits is based on three sets of observations (Scheffers and Kelletat, 2003). The first is that the long axes of many coastal chevron complexes are not oriented parallel to the direction of the prevailing wind. The second is that some chevron complexes extend several kilometers (km) inland and rise to over 100 meters (m) above sea level. Some of these chevron complexes are located on shorelines that lack beaches. In these particular cases, it is difficult to understand how either megastorms or wind could have formed the chevrons. Megastorms cannot move subaerial rock and sediment over km-scale distances with elevation gains of hundreds of meters (Cox et al., 2012; Erdmann et al., 2015). Wind cannot move sediment inland if there are no subaerial, poorly consolidated sediments on the coast. In this chapter, we describe three chevron complexes, V-shaped, elongated dune complexes on the southern coast of Madagascar. Their origin is disputed because individual dunes are elongated along an azimuth that is close to the direction of the prevailing winds (Abbott et al., 2008; Pinter and Ishman, 2008), although their low angle of deposition generally is inconsistent with aeolian dunes. However, other characteristics preclude their derivation from modern beach deposits, although we do not discount later aeolian reworking of some chevron deposits. In particular, the Madagascar chevrons contain significant proportions of early Holocene carbonate tests resembling shells of marine foraminifera, including some that are partially dolomitized, and some that are infilled with mud. These observations suggest that marine carbonate tests in the chevrons were eroded from the continental shelf, and not from modern beaches. Furthermore, despite having lateral extents of tens of km, characteristics of the chevrons (degree of sediment sorting, carbonate content, and marine microfossil concentrations) do not change significantly along strike, as might be expected for aeolian deposits.

description: This paper provides some examples of women’s writing in dialogue with God. A premise of the text is that “God” is a word alluding to the opening up of the impossible into necessity. The women’s texts selected are Etty Hillesum’ Diary and Caterina da Siena’s Dialogue, followed by Antonietta Potente’s discourse as a commentary on the Gospel of Thomas. From these three examples, the centrality of the infinite emerges as an opening moment within historical time. The infinite is presented as belonging to the experimental experience accompanied by the discourse. The reference to experimental experience and discourse, never fully complete and harmonious, is indicated as being characteristic of this genre of women’s writing.

description: The question of the value of the pitch angle of DNA is visited from the perspective of a geometrical analysis of transcription. It is suggested that for transcription to be possible, the pitch angle of B-DNA must be smaller than the angle of zero-twist. At the zero-twist angle the double helix is maximally rotated and its strain-twist coupling vanishes. A numerical estimate of the pitch angle for B-DNA based on differential geometry is compared with numbers obtained from existing empirical data. The crystallographic studies shows that the pitch angle is approximately 38 deg., less than the corresponding zero-twist angle of 41.8 deg., which is consistent with the suggested principle for transcription.

Applying the virtual structure of a risk-informed decision making framework for operating small hydropower reservoirs during high inflow events, case study : Cheakamus River system
Creators: name: Alipour, Mohammadhossein
Publisher: name: University of British Columbia
Year: 2012

description: Operating hydropower reservoirs with small storage capacity is a challenging task due to the fact that in a watershed system there usually exist multiple stakeholders with different and conflicting preferences and values. Consequently the process of planning for reservoir operation must be carried out with consideration of several, usually competing, objectives. This process becomes even more challenging during a high inflow or flooding event for three main reasons. First, the objective of minimizing adverse consequences of such an event is added to the set of objectives that the operator must deal with. Second, inflow forecast uncertainty-driven risks are highly intensified due to the high sensitivity of the outcomes to inflow forecasts. And third, the available time for making a decision is very short while comprehensive analysis is a necessity in order to make an informed decision regarding the best operational alternative. Under these circumstances, the best approach to confront this challenge could be developing a Risk-Informed Decision Making (RIDM) framework that provides operation planning engineers with a solid and pre-designed guideline to deal with the task of identifying the best operational alternative in an efficient and timely manner. The current study is an attempt to apply the virtual structure of a RIDM framework for the Cheakamus River system in British Columbia. The framework is a coherent assembly of a number of methods and tools we have either developed or utilized from the existing widely used methods and techniques in practice. The product of our work is an example of the necessary tools that need to be used to develop recommendations for operating Daisy Lake reservoir during a high inflow event in a manner that all the operational objectives are served in the best possible way. This is done while taking into account making trade-offs among competing objectives. We illustrate the practical applicability and merits of the framework through applying it to a historical high inflow period in October 2003. The outcome is near real-time decisions with less dependency on only planners’ judgement and more dependency on thorough and systematic analysis with consideration of human judgement and possible risk tolerances.

description: This paper describes an improved parameterization for proton-beryllium production of secondary $K^{+}$ mesons for experiments with primary proton beams from 8.89 to 24 GeV. The parameterization is based on Feynman scaling in which the invariant cross section is described as a function of $x_{F}$ and $p_{T}$. This method is theoretically motivated and provides a better description of the energy dependence of kaon production at low beam energies than other parameterizations such as the commonly used "Modified Sanford-Wang" model. This Feynman scaling parameterization has been used for the simulation of the neutrino flux from the Booster Neutrino Beam (BNB) at Fermilab and has been shown to agree with the neutrino interaction data from the SciBooNE experiment. This parameterization will also be useful for future neutrino experiments with low primary beam energies, such as those planned for the Project X accelerator.

description: Doctors need to consistently maintain their clinical performance across a range of different situations by managing the stress response provoked by these situations. Six performance-related adaptive and maladaptive psychological characteristics and psychological skills can distinguish between how athletes manage their stress response and consistently maintain an optimal level of performance across a variety of situations. The aim of the study was to understand how the performance-related psychological characteristics and skills identified in athletes are applied by doctors. An exploratory qualitative study was conducted with semi-structured interviews. A purposive sample of 10 doctors were interviewed and the data were analysed by template analysis. Doctors have similar performance-related psychological characteristics and skills as identified in athletes for managing their stress response to consistently maintain optimal clinical performance. The importance of maladaptive characteristics was also identified, especially in junior doctors. The findings of this pilot study can be used for informing the design of performance-related educational interventions for doctors to manage their stress response for consistently maintaining optimal clinical performance. An important consideration will need to be a focus on specific groups in their career journey and the development of a multi-dimensional, reflective, and problem-solving approach.

description: We present a multiperiod agency model of stock based executive compensation in a speculative stock market, where investors have heterogeneous beliefs and stock prices may deviate from underlying fundamentals and include a speculative option component. This component arises from the option to sell the stock in the future to potentially overoptimistic investors. We show that optimal compensation contracts may emphasize short-term stock performance, at the expense of long run fundamental value, as an incentive to induce managers to pursue actions which increase the speculative component in the stock price. Our model provides a different perspective on the recent corporate crisis than the "rent extraction view" of executive compensation.

description: On 29 October 1923, radio broadcasting or “Rundfunk” was officially opened in the Voxhaus in Berlin and thus the new communication medium was now also available in Germany, but later than in other countries such as the US and the UK. However, first experiments with wireless telephony, which is the technical basis of this medium, were carried out more than ten years earlier (Pungs, 1922; Mathis, 2019; Titze and Mathis, 2020; Mathis and Titze, 2021). One of the pioneers of this technology was the German Egbert von Lepel, who developed in 1907 a new concept of wireless transmitters that was also suitable for use in wireless telephony. The concept later became known as the quenched spark-gap transmitter (“Löschfunkensender”) or ”Singing Spark” transmitter where a specific variant was developed by the Gesellschaft für Drahtlose Telegraphie (GDT: “Wireless Telegraph Society”), System Telefunken. This article discusses the history of this type of transmitter using new historical sources from national and international archives. It turns out that contrary to what is known on this subject from almost all publications on the history of early wireless technology, the German Imperial Patent Office decided in January 1911 that Lepel's patent was granted as the most fundamental for quenched spark-gap transmitters. With the disclosure of this important historical source, the question of the origin of the invention of the quenched spark-gap transmitter must be reassessed.

description: Medical students can experience a range of academic and non-academic struggles. Coaching is a valuable strategy to support learners, but coaches describe working with struggling learners as taxing. Transformative learning theory (TLT) provides insights into how educators grow from challenging experiences to build resilience. This study explores how coaches evolve as educators through supporting struggling students. This qualitative study grounded in an interpretivist paradigm used interviews of longitudinal medical student coaches at two academic institutions. Interviews, using TLT as a sensitizing concept, explored coaches’ experience coaching struggling learners. We performed thematic analysis. We interviewed 15 coaches. Coaches described supporting students through multi-faceted struggles which often surprised the coach. Three themes characterized coaches’ experiences: personal responsibility, emotional response, and personal learning. Coaches shouldered high personal responsibility for learners’ success. For some, this burden felt emotional, raised parental instincts and questions about maintaining boundaries with learners. Coaches evolved their coaching approach, challenged biases, and built skills. Coaches learned to better appreciate the learner point of view and employ resources to support students. Through navigating learner struggles, educators can gain self-efficacy, learn to understand learners’ perspectives, and evolve their coaching approach to lessen their personal emotional burden through time.
title: A fisheries management system in crisis - the EU Common Fisheries Policy

description: No abstracts are to be cited without prior reference to the author.The crisis in EU fisheries management has prevailed almost since the Common Fisheries Policy (CFP) was first implemented in 1983. Despite tremendous effort and resources having been invested in improving the performance of the CFP the crisis worsens year by year. The Commission has clearly expressed the short-comings of the CFP both in connection with its revision in 1992 (CEC 1991) and its reform in 2002 (CEC 2001) and will repeat them again in the up-coming issue paper reviewing the CFP (CEC 2009). This paper will synthesis the complex social, economic and political system influenced by – or perhaps defined by - the CFP, the interaction of many explanatory factors. Different theoretical and analytical perspectives will be applied to highlight the various factors and processes that influence the CFP. The aim is to uncover the main factors influencing the CFP and to provide some direction on how to improve the CFP for the future. The paper concludes by proposing that the CFP is revised to enhance regionalisation and devolution of management responsibilities to the fishing industry in conjunction with a results-based management approach. Particular the institutional structure of the CFP should be transform into a suite of de facto eco-region fisheries policies to overcome the present problems of having a common policy that attempts to manage almost all aspects of a very fragmented sector across very different eco-systems that in reality have very few commonalities
A proposed feedback model for the objective structured clinical examination (OSCE) in health and medical education

description: The objective structured clinical examination (OSCE) is used extensively in health and medical education to assess clinical competence. While OSCEs are not primarily designed for individual feedback, they provide an opportunity to generate meaningful and constructive feedback that students can use to reflect on areas of weakness (and strength). The most timely and effective way to incorporate individual feedback following a summative OSCE continues to be explored. This paper describes a novel OSCE feedback model which uses readily available summative assessment data to calculate 10% index scores. This provides information about relative station difficulty and relative individual student performance. An individualised feedback report was provided to every student after the OSCEs. This enables identification of stronger and weaker performance areas and composite skills, which can be utilised by all students to direct future learning. Providing timely, individual actionable feedback to every student following a summative OSCE is possible without impacting the examination process or examiner burden. A study is planned to determine the utilisation of this feedback by students and it’s impact as a qualitative self-assessment exercise.

description: Thank you to Professor June Besek, and thanks to everyone here at Columbia for the invitation. June, to correct one of your introductions here—Mark McKenna is too humble to say so, but in addition to being a widely recognized scholar, he was elected yesterday to the American Law Institute, which is well deserved given his immense contributions to Intellectual Property Law scholarship. Mark and I have talked about this topic, in part in preparation for today, and so a lot of what I say is going to reflect some of what he has said, and I think that is fine. (There are worse things you can say about a scholar than, “oh, he sounds just like McKenna.”) One of the things that has come up in the discussions this morning and on this panel—which considers the scope of the Intellectual Property right of the Right of Publicity, and whether it is an Intellectual Property right or not—is the relationship between scope and justification. Mark’s comments suggest that there is no such relationship with respect to the Right of Publicity; or, that at least it is loose. The biggest contribution of Jennifer’s excellent book is to encourage us to think about the rights of publicity and the rights of privacy as different things that have— for odd historical reasons, some of them with a purpose—been lumped together. And that we ought to try to think about them more separately and their justifications more separately.
Electrical properties of dislocations within the nitride based semiconductors gallium nitride and indium nitride

description: Dislocation lines affect the electrical and optical properties of semiconductors. In this research, the effect that the threading dislocation lines have on the free electron concentration and the electron mobility within gallium nitride and indium nitride is investigated. A formulation is developed for obtaining the screening space charge concentration and the corresponding electrostatic potential profile surrounding the dislocation lines. The resultant electrostatic potential profile has then been used to compute the associated electron mobility, limited by scattering from the charged dislocation lines. As part of this research, a Gibbs factor formalism is also developed that can readily obtain the occupation statistics of the defect sites associated with the threading dislocation lines.
