Social movement sustainability : an analysis of the rift between HIV positive and HIV negative gay men and its impact on the gay liberation movement
Creators: name: Botnick, Michael R.
Publisher: name: University of British Columbia
Year: 2009

description: There is a growing rift between HIV-positive and HIV-negative gay men, manifested in social, economic, structural and political divisiveness which, if not resolved may 'kill' the gay liberation movement. While disasters generally create organizational solidarity, AIDS has operated in reverse, spawning a variety of competitive AIDS service organizations, alienating seropositive gays from the mainstream gay community, and disenfranchising seronegative gay men as human and financial resources are redirected towards persons living with HIV and AIDS. Serostatus has become a social marker of societal status, operating in a bimodal discriminatory manner. Seronegative gay men experience discrimination within the gay community as funding for and services to this sector diminish. Seropositive gay men (and the organizations which provide for some of their needs) have culturally, economically and socially dismissed the needs of seronegative gay men (survivor guilt, safer sex education, etc) in favour of providing social and resource based services to seropositive gay men. The social distance between the gay movement and the AIDS movement has correspondingly increased. If this trend continues, it will serve to further push HIVpositive and HIV-negative gay men into polarized camps, resulting in a wider separation of the gay movement from the AIDS movement. The stigmatization of HIV-positive people will subsequently increase both within and outside of the gay movement, and any ability to present a unified Gay Liberation front will correspondingly diminish. Additionally, the emergent notion that to be gay is to be HIV-positive will solidify. This will a) further stigmatize all gay men in the eyes of the non-gay population, and b) exacerbate the rift between HIV-positive and HIV-negative gay men within the gay community, reversing the stigma of HIV such that to be HIV-negative will be a marker of non-gay identity. In short, seropositivity will become the defining element of gayness. In order to avert further divisiveness, and minimization of the gay movement, an effort must be made towards reestablishing the original ideology of cooperation, which was the hallmark of the earlier days of AIDS activism. This will require a debureaucratization of AIDS service organizations; coalition building among AIDS service organizations and gay liberation organizations; and personal attitudinal and behaviour changes on the part of both seropositive and seronegative gays regarding HIV status as a medical, rather than social phenomenon.

description: At a critical finite chemical potential and low temperature QCD undergoes the chiral restoration phase transition. The folklore tradition is that simultaneously hadrons are deconfined and there appears the quark matter. We demonstrate that it is possible to have confined but chirally symmetric hadrons at a finite chemical potential and hence beyond the chiral restoration point at a finite chemical potential and low temperature there could exist a chirally symmetric matter consisting of chirally symmetric but confined hadrons. If it does happen in QCD, then the QCD phase diagram should be reconsidered with obvious implications for heavy ion programs and astrophysics.

description: Gyrochronology allows the derivation of ages for cool main sequence stars based on their observed rotation periods and masses, or a suitable proxy thereof. It is increasingly well-explored for FGK stars, but requires further measurements for older ages and K-M-type stars. We study the nearby, 3 Gyr-old open cluster Ruprecht 147 to compare it with the previously-studied, but far more distant, NGC 6819 cluster, and especially to measure cooler stars than was previously possible there. We constructed an inclusive list of 102 cluster members from prior work, including Gaia DR2, and for which light curves were also obtained during Campaign 7 of the Kepler/K2 space mission. [...] Periodic signals are found for 32 stars, 21 of which are considered to be both highly reliable and to represent single, or effectively single, Ru147 stars. These stars cover the spectral types from late-F to mid-M stars, and they have periods ranging from 6d-32d, allowing for a comparison of Ruprecht 147 to both of the other open clusters and to models of rotational spindown. The derived rotation periods connect reasonably to, overlap with, and extend to lower masses the known rotation period distribution of the 2.5 Gyr-old cluster NGC 6819. The data confirm that cool stars lie on a single surface in rotation period-mass-age space, and they simultaneously challenge its commonly assumed shape. The shape at the low mass region of the color-period diagram at the age of Ru147 favors a recently-proposed model, which requires a third mass-dependent timescale in addition to the two timescales required by a former model, suggesting that a third physical process is required to model rotating stars effectively.

description: This paper aims to assess the effects of industrial pollution on infant mortality between the years 1850-1940 using full count decennial censuses. In this period, US economy experienced a tremendous rise in industrial activity with significant variation among different counties in absorbing manufacturing industries. Since manufacturing industries are shown to be the main source of pollution, we use the share of employment at the county level in this industry to proxy for space-time variation in industrial pollution. Since male embryos are more vulnerable to external stressors like pollution during prenatal development, they will face higher likelihood of fetal death. Therefore, we proxy infant mortality with different measures of gender ratio. We show that the upswing in industrial pollution during late nineteenth century and early twentieth century has led to an increase in infant mortality. The results are consistent and robust across different scenarios, measures for our proxies, and aggregation levels. We find that infants and more specifically male infants had paid the price of pollution during upswing in industrial growth at the dawn of the 20th century. Contemporary datasets are used to verify the validity of the proxies. Some policy implications are discussed.

description: Using the texts of the poet and literary scholar Przemysław Dakowicz as an example, this article analyzes how the traditional martyrological discourse of the ‘romantic paradigm’ (Maria Janion) is revived in contemporary Polish poetry. The aesthetic and political instrumentalization of the symbolic link between the mass execution of Katyń in 1940 and the air crash of Smolensk in 2010 is of particular importance in this context, and, in approaching these subjects, I will suggest reading Dakowicz’s obsessive interest in the physical remains of the dead as a poetic implementation of the forensic turn that has critically manifested itself in recent years in the research of mass violence and crimes of genocide. In my discussion of the historical-political and poetic implications of this turn, I argue that Dakowicz performs a shift from the perspective of the witness to an event to that of the witness to the exhumation of physical remains and that this is how his professional background as a literary scholar comes into play. In dealing with the remnants of dead bodies, Dakowicz engages competing strategies of archiving (sighting, sifting, and safekeeping) on the one hand and hermeneutics (interpretation, revitalization) on the other. The works of the Polish historian Ewa Domańska serve as further theoretical background to this discussion (“Nekros: Introduction to the Ontology of the Dead Body,“ 2017, in Polish).
On the problem of the relation between phason elasticity and phason dynamics in quasicrystals

description: It has recently been claimed that the dynamics of long-wavelength phason fluctuations has been observed in i-AlPdMn quasicrystals. We will show that the data reported call for a more detailed development of the elasticity theory of Jaric and Nelsson in order to determine the nature of small phonon-like atomic displacements with a symmetry that follows the phason elastic constants. We also show that a simple model with a single diffusing tile is sufficient to produce a signal that (1) is situated at a "satellite position'' at a distance q from each Bragg peak, that (2) has an intensity that scales with the intensity of the corresponding Bragg peak, (3) falls off as 1/q-squared and (4) has a time decay constant that is proportional to 1/(D q-squared). It is thus superfluous to call for a picture of "phason waves'' in order to explain such data, especially as such "waves'' violate many physical principles.

Entanglement of electrons and the lattice in a Luttinger system

description: The coupling between electronic and lattice degrees of freedom lies at the core of many important properties of solids. Nevertheless, surprisingly little is know about the entanglement between these degrees of freedom. We here calculate the entanglement entropy at zero temperature as well as the mutual information and the entanglement negativity at finite temperatures between the electrons and the lattice of a one-dimensional chain. The electrons are described within Luttinger-liquid theory. Our results show that the entanglement entropy diverges when one approaches the limit of stability, the so-called Wentzel-Bardeen singularity. We have found that the mutual information and the entanglement negativity decrease with the temperature. The mutual information reaches a finite value in the infinite-temperature limit, which is the consequence of the infinite linear electron spectrum of Luttinger theory. The entanglement negativity becomes exactly zero above a certain temperature, i.e., the lattice and the electrons become non-entangled above this temperature. If the electron-electron interaction is unscreened or weakly screened, this characteristic temperature diverges with the system size. However, if the interaction is strongly screened the characteristic temperature is finite and independent of the system size.

description: In this review paper, we summarise the goals of asteroseismic studies of close binary stars. We first briefly recall the basic principles of asteroseismology, and highlight how the binarity of a star can be an asset, but also a complication, for the interpretation of the stellar oscillations. We discuss a few sample studies of pulsations in close binaries and summarise some case studies. This leads us to conclude that asteroseismology of close binaries is a challenging field of research, but with large potential for the improvement of current stellar structure theory. Finally, we highlight the best observing strategy to make efficient progress in the near future.

description: We construct M-theory on the orbifold C^2/Z_N by coupling 11-dimensional supergravity to a seven-dimensional Yang-Mills theory located on the orbifold fixed plane. It is shown that the resulting action is supersymmetric to leading non-trivial order in the 11-dimensional Newton constant. This action provides the starting point for a reduction of M-theory on G_2 spaces with co-dimension four singularities.

description: This article examines “China” in contemporary American poetry using the example of Timothy Yu’s poems, titled “Chinese Silence,” which rewrite and / or parody texts from the American literary canon as well as public communication. It proposes a hall-of-mirrors reading of these poems in order to show how Yu’s poems refer to, reflect on, and relocate other authors’ writing of “China.” It argues that Yu’s poems, instead of making claims for an authentic “China,” attempt to bring Chinese Americans’ lived experience into the American literary tradition.
Seismological constraints on the solar coronal heating function

description: The hot solar corona exists because of the balance between radiative and conductive cooling and some counteracting heating mechanism which remains one of the major puzzles in solar physics. The coronal thermal equilibrium is perturbed by magnetoacoustic waves which are abundantly present in the corona, causing a misbalance between the heating and cooling rates. Due to this misbalance, the wave experiences a back-reaction, either losing or gaining energy from the energy supply that heats the plasma, at the time scales comparable to the wave period. In particular, the plasma can be subject to wave-induced instability or over-stability, depending on the specific choice of the coronal heating function. In the unstable case, the coronal thermal equilibrium would be violently destroyed, which does not allow for the existence of long-lived plasma structures typical for the corona. Based on this, we constrained the coronal heating function using observations of slow magnetoacoustic waves in various coronal plasma structures.

description: The aim of the present thesis is the concept of the salary in contract employee. In the first chapter, we tried to present a complete definition of the concept of the salary, while parallel we examined its multilateral nature and the legislative base of the salary base as well. Furthermore, we analyze some cases of wage benefits, whose character wage is grounded, for example the voluntary benefits, the compensations, the benefits which serve functional needs of the enterprise and the gratuities. Moreover, we examined the valuation of the work provided, depending on its type, in the cases of similar works and subtasks and in the case of part time employment. In the second chapter, we referred in the discriminations of the salary, depending on the legal method for its determination and more precisely we analyzed the concepts of the conventional salary, the legal salary and the ordinary salary, as well as the principles which rules them. Finally, in the last section of this thesis, we examined the cases where the arrangement of an employment relationship by a wage view, is regulated by several legislative sources, like the individual employment contract, the collective agreements or other legislative provisions.

description: We formulate Quantum Energy Inequalities (QEIs) in the framework of locally covariant quantum field theory developed by Brunetti, Fredenhagen and Verch, which is based on notions taken from category theory. This leads to a new viewpoint on the QEIs, and also to the identification of a new structural property of locally covariant quantum field theory, which we call Local Physical Equivalence. Covariant formulations of the numerical range and spectrum of locally covariant fields are given and investigated, and a new algebra of fields is identified, in which fields are treated independently of their realisation on particular spacetimes and manifestly covariant versions of the functional calculus may be formulated.

description: The present common view about GRB origin is related to cosmology, what is based on statistical analysis, and on measurements of the redshifts in the GRB optical afterglows of long GRB. Models of radiation, and models of the central machine for GRB are critically analyzed. Most of these models cannot produce the amount of energy required for the cosmological GRB. Collimation is needed to reduce GRB energy output. No correlation is found between redshifts, GRB spectrum, and total GRB fluence. Comparison of KONUS and BATSE data about statistics and hard X-ray lines is done, and some differences are noted. Hard gamma-ray afterglows, prompt optical spectra, hard X-ray lines measurements could be important for farther insight into GRB origin. Two bright optical afterglows had been detected, indicating that initial bright optical emission is directly connected with the GRB itself, and has a different origin from the subsequent faint optical emission. Results of these observations are represented. Observations indicate that GRB originate in star forming regions of galaxies with a high matter density. Interaction of the mighty gamma ray flux from the cosmological GRB with the dense surrounding molecular cloud lead to long optical afterglow, lasting up to 10 years, due to reradiation of the cloud. Results of numerical simulations of such reradiation for different forms of clouds are represented. Possible connection of short GRB with soft gamma repeaters is discussed.

description: We address the reflection of vector solitons, comprising several components that exhibit multiple field oscillations, at the interface between two nonlinear media. We reveal that reflection causes fission of the input signal into sets of solitons propagating at different angles. We find that the maximum number of solitons that arises upon the fission is given by the number of field oscillations in the highest-order input vector soliton.

description: This work has devised a methodology to separate the mixture of ethyl acetate and isopropyl alcohol, which forms a minimum boiling azeotrope into pure streams using an entrainer in the extractive distillation (ED) column. Binary vapour liquid equilibrium (VLE) data were obtained from relevant literature and various thermodynamic models were used for prediction. Heuristics and rules of thumb were used for short–listing the model. Correct prediction of VLE and ability of the model to predict azeotrope were used as a criterion to select the best model, to develop the ED process. Modelling, simulation and economic analysis were conducted to select the more effective entrainer between dimethyl sulfoxide (DMSO) and dimethyl formamide (DMF). Sensitivity analysis was used to obtain a sensible range of parameters. Experiments were conducted using the chosen entrainer to qualitatively validate predictions. It was observed that almost pure components are obtained and the entrainer is recovered almost completely. Overall flowsheet of separation is proposed.

description: Questo contributo indaga sulla questione come mai in ambito protestante, nonostante il «principio scritturale», la classica omelia sia stata poco praticata. Anzitutto, da Lutero in poi si nota una comprensione qualitativa del riferimento scritturale (tipicamente nei termini di «legge» e «vangelo»), che favoriva un’impostazione tematica del sermone. Inoltre, dal tardo XVII secolo lo studio biblico in comunità offriva al serrato confronto con il testo una sede alternativa. Solo nel XX secolo, gli impulsi provenienti dalla teologia dialettica e, poi, le metodologie omiletiche narrative ed esperienziali hanno incoraggiato una sorta di recupero dell’omelia.

Heat capacity measurement of YBa₂Cu₃O7 -- 197

Publisher: name: University of British Columbia

description: A modified AC method is developed for measuring the specific heat of very small high quality single crystal samples of Y₁B₂C₃O6+x (Yttrium Barium Copper Oxide). The system developed combines the original AC calorimetry method introduced by Sullivan et al. and the thermal relaxation method by Bachmann et al. The modification involves the use of a sapphire as substrate to support the crystal, heater and the temperature sensor. A complete thermal analysis of the experimental setup is presented in addition to a detailed experimental procedure for measuring the heat capacity of a small sample. Some experimentation with diamond substrate is performed as well and compared with sapphire. Another feature added to our AC calorimetry setup is a Dewar pressure regulation system. This was to minimize the variations in the liquid bath temperature due to changes in ambient pressure. Our system also allows for multiple sweeps, as bath temperature is monitored, from which the best sweeps corresponding to the most stable temperature interval is chosen for further analysis. Considering the different mathematical models developed so far for explaining the behavior of the specific heat fluctuation of YBCO, our results seem to support the 3D XY model near the transition temperature of 93.IK. From the heat capacity data our crystal sample showed a transition width, ΔTc, of 0.45K, and a superconducting transition jump ACp, of 6.1mJ/gK.

description: The nature of the evolution of the magnetic field, and of current sheet formation, at three-dimensional (3D) magnetic null points is investigated. A kinematic example is presented which demonstrates that for certain evolutions of a 3D null (specifically those for which the ratios of the null point eigenvalues are time-dependent) there is no possible choice of boundary conditions which renders the evolution of the field at the null ideal. Resistive MHD simulations are described which demonstrate that such evolutions are generic. A 3D null is subjected to boundary driving by shearing motions, and it is shown that a current sheet localised at the null is formed. The qualitative and quantitative properties of the current sheet are discussed. Accompanying the sheet development is the growth of a localised parallel electric field, one of the signatures of magnetic reconnection. Finally, the relevance of the results to a recent theory of turbulent reconnection is discussed.

description: We present a mean-field solution for a quantum, short-range interacting, disordered, SO(3) Heisenberg spin model, in which the Gaussian distribution of couplings is centered in an AF coupling $\bar J>0$, and which, for weak disorder, can be treated as a perturbation of the pure AF Heisenberg system. The phase diagram contains, apart from a Néel phase at T=0, spin-glass and paramagnetic phases whose thermodynamic stability is demonstrated by an analysis of the Hessian matrix of the free-energy. The magnetic susceptibilities exhibit the typical cusp of a spin-glass transition.

description: We report the results of a high temporal resolution spectroscopic monitoring of the flare star AD Leo. During 4 nights, more than 600 spectra were taken in the optical range using the Isaac Newton Telescope (INT) and the Intermediate Dispersion Spectrograph (IDS). We have observed a large number of short and weak flares occurring very frequently (flare activity > 0.71 hours-1). This is in favour of the very important role that flares can play in stellar coronal heating. The detected flares are non white-light flares and, though most of solar flares belong to this kind, very few such events had been previously observed on stars. The behaviour of different chromospheric lines (Balmer series from H_alpha to H_11, Ca II H & K, Na I D_1 & D_2, He I 4026 AA and He I D_3) has been studied in detail for a total of 14 flares. We have also estimated the physical parameters of the flaring plasma by using a procedure which assumes a simplified slab model of flares. All the obtained physical parameters are consistent with previously derived values for stellar flares, and the areas - less than 2.3% of the stellar surface - are comparable with the size inferred for other solar and stellar flares. Finally, we have studied the relationships between the physical parameters and the area, duration, maximum flux and energy released during the detected flares.

description: OBJECTIVE: To determine whether vitamin D supplementation influences grip strength, explosive leg power, cardiorespiratory fitness and risk of exercise-induced bronchoconstriction (EIB) in South African schoolchildren. METHODS: Substudy (n=450) in Cape Town schoolchildren aged 8-11 years nested within a phase 3 randomised placebo-controlled trial (ViDiKids). The intervention was weekly oral doses of 10 000 IU vitamin D3 (n=228) or placebo (n=222) for 3 years. Outcome measures were serum 25-hydroxyvitamin D3 (25(OH)D3) concentrations, grip strength, standing long jump distance, peak oxygen uptake (VO2peak, determined using 20 m multistage shuttle run tests) and the proportion of children with EIB, measured at end-study. RESULTS: 64.7% of participants had serum 25(OH)D3concentrations <75 nmol/L at baseline. At 3-year follow-up, children randomised to vitamin D versus placebo had higher mean serum 25(OH)D3 concentrations (97.6 vs 58.8 nmol/L, respectively; adjusted mean difference 39.9 nmol/L, 95% CI 36.1 to 43.6). However, this was not associated with end-study differences in grip strength, standing long jump distance, VO2peak or risk of EIB. CONCLUSION: A 3-year course of weekly oral supplementation with 10 000 IU vitamin D3 elevated serum 25(OH)D3 concentrations in South African schoolchildren but did not influence muscle strength, exercise capacity or risk of EIB.

description: The encapsulation-dehydration and vitrification techniques were experimented for freezing apices of pineapple in vitro plantlets. Positive results were achieved using vitrification only. Optimal conditions included a 2-d preculture of apices on medium supplemented with 0.3M sucrose, loading treatment for 25 min in medium with 0.75M sucrose + 1M glycerol and dehydration with PVS2 vitrification solution at 0 degrees C for 7 h before rapid freezing in liquid nitrogen. This method resulted in 65, 35 and 25% survival with apices of varieties Puerto Rico, Perolera and Smooth Cayenne, respectively. Recovery of cryopreserved apices took place directly, without transitory callus formation.

Long Secondary Periods and Binarity in Red Giant Stars

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Observational arguments supporting the binary explanation of the long secondary periods (LSP) phenomenon in red giants are presented. Photometry of about 1200 semiregular variables with the LSP in the Large Magellanic Cloud are analyzed using the MACHO and OGLE photometry. For about 5% of these objects additional ellipsoidal-like or eclipsing-like modulation with the same periods as the LSP is detectable. These double-humped variations are usually shifted in phase comparing to the LSP light curves. I discuss the model of binary system with a red giant as the primary component and a low-mass object as the secondary one. The mass lost by the red giant through the wind follows the spiral pattern in the orbit around the primary star and obscures it causing the LSP variations.

Solid reductions and nutrient flows in biological phosporus sludge using thermophilic aerobic digestion
Creators: name: Cross, Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: This study was on autothermal thermophilic aerobic digestion (ATAD) of "Biological Nutrient Removal" (BNR) sludge. Solids and nutrient balances were performed using 2 bench scale thermophilic aerobic digesters operated in series. In total there were 4 reactors; 2 series running in parallel. The digesters were fed waste activated sludge from a biological phosphorous removal treatment plant located in Penticton, B.C. Four experiments were completed, each under different aeration conditions and different hydraulic retention times i.e. a 2x2 factorial design. The aeration conditions were defined by a combination of airflow, oxidation reduction potential and dissolved oxygen measurements. The hydraulic retention times that were investigated were 24 hours and 48 hours and the aeration rates used in conjunction with them were 0.5 L/min and 1.5 L/min. The overall findings were that this type of treatment was extremely successful in decreasing chemical oxygen demands (COD) and solids levels. In the low air flow experiments the decrease in COD and solids values were, 35.5% and 45% respectively, and in the high air flow experiments they were 26.5% and 33% respectively. Orthophosphates were noted to increase significantly (+8%) in the low air flow experiments when compared to the high air flow experiments (-12.5%) i.e. therefore there was absorption of the orthophosphates happening in the high air experiments. The total kjeldahl nitrogen (TKN) values were found to decrease by 30% in the low air experiments and 27.5% in the high air flow experiments. The liquid phase nitrogen increased by 134% in the low air experiment and by 124% in high air flow experiments.

description: Non-Newtonian calculus naturally unifies various ideas that have occurred over the years in the field of generalized thermostatistics, or in the borderland between classical and quantum information theory. The formalism, being very general, is as simple as the calculus we know from undergraduate courses of mathematics. Its theoretical potential is huge, and yet it remains unknown or unappreciated.

description: In this talk we report on recent results for the quark propagator on a compact manifold. The corresponding Dyson-Schwinger equations on a torus are solved on volumes similar to the ones used in lattice calculations. The quark-gluon interaction is fixed such that the lattice results are reproduced. We discuss both the effects in the infinite volume/continuum limit as well as effects when the volume is small.
