description: Effects of impurity scatterings on the strong coupling (SC) contribution, stabilizing the ABM (axial) pairing state, to the quartic term of the Ginzburg-Landau (GL) free energy of superfluid $^3$He are theoretically studied to examine recent observations suggestive of an anomalously small SC effect in superfluid $^3$He in aerogels. To study the SC corrections, two approaches are used. One is based on a perturbation in the short-range repulsive interaction, and the other is a phenomenological approach used previously for the bulk liquid by Sauls and Serene [Phys.Rev.B 24, 183 (1981)]. It is found that the impurity scattering favors the BW pairing state and shrinks the region of the ABM pairing state in the T-P phase diagram. In the phenomenological approach, the resulting shrinkage of the ABM region is especially substantial and, if assuming an anisotropy over a large scale in aerogel, leads to justifying the phase diagrams determined experimentally.

description: The extended lobes of radio galaxies are examined as sources of X-ray and gamma-ray emission via inverse Compton scattering of 3K background photons. The Compton spectra of two exemplary examples, Fornax A and Centaurus A, are estimated using available radio measurements in the ~10's MHz - 10's GHz range. For average lobe magnetic fields of >~0.3-1 micro-G, the lobe spectra are predicted to extend into the soft gamma-rays making them likely detectable with the GLAST LAT. If detected, their large angular extents (~1 deg and 8 deg) will make it possible to ``image'' the radio lobes in gamma-rays. Similarly, this process operates in more distant radio galaxies and the possibility that such systems will be detected as unresolved gamma-ray sources with GLAST is briefly considered.

description: We continue our study of contour deformation as a practical tool for dealing with the sign problem using the $d$-dimensional Bose gas with non-zero chemical potential as a toy model. We derive explicit expressions for contours up to the second order with respect to a natural small parameter and generalise these contours to an ansatz for which the evaluation of the Jacobian is fast ($O(1)$). We examine the behaviour of the various proposed contours as a function of space-time dimensionality, the chemical potential, and lattice size and geometry and use the mean phase factor as a measure of the severity of the sign problem. In turns out that this method leads to a substantial reduction of the sign problem and that it becomes more efficient as space-time dimensionality is increased. Correlations among contributions to $\operatorname{Im}\langle S \rangle$ play a key role in determining the mean phase factor and we examine these correlations in detail.

description: The Cs2CO3-promoted P-N coupling reaction of H-phosphoryl compounds and N-tosylhydrazones is reported. Formally, this transformation represents an interesting example of exchanging the sulfur and phosphorus functionalities to convert N-tosylhydrazones to N-phosphorylhydrazones. The reaction may take place via the nucleophilic interception of the in-situ generated diazo intermediates by H-phosphoryl compounds at the terminal nitrogen atom.

description: We present a learning-based method for building driving-signal aware full-body avatars. Our model is a conditional variational autoencoder that can be animated with incomplete driving signals, such as human pose and facial keypoints, and produces a high-quality representation of human geometry and view-dependent appearance. The core intuition behind our method is that better drivability and generalization can be achieved by disentangling the driving signals and remaining generative factors, which are not available during animation. To this end, we explicitly account for information deficiency in the driving signal by introducing a latent space that exclusively captures the remaining information, thus enabling the imputation of the missing factors required during full-body animation, while remaining faithful to the driving signal. We also propose a learnable localized compression for the driving signal which promotes better generalization, and helps minimize the influence of global chance-correlations often found in real datasets. For a given driving signal, the resulting variational model produces a compact space of uncertainty for missing factors that allows for an imputation strategy best suited to a particular application. We demonstrate the efficacy of our approach on the challenging problem of full-body animation for virtual telepresence with driving signals acquired from minimal sensors placed in the environment and mounted on a VR-headset.

description: A new Z-basis for the space of quasisymmetric functions (QSym, for short) is presented. It is shown to have nonnegative structure constants, and several interesting properties relative to the space of quasisymmetric functions associated to matroids by the Hopf algebra morphism (F) of Billera, Jia, and Reiner. In particular, for loopless matroids, this basis reflects the grading by matroid rank, as well as by the size of the ground set. It is shown that the morphism F is injective on the set of rank two matroids, and that decomposability of the quasisymmetric function of a rank two matroid mirrors the decomposability of its base polytope. An affirmative answer is given to the Hilbert basis question raised by Billera, Jia, and Reiner.

The collected poetry of Malcolm Lowry : a critical edition with a commentary
Creators: name: Scherf, Kathleen Dorothy
Publisher: name: University of British Columbia
Year: 2010

description: Although his literary reputation rests primarily on his novels, Malcolm Lowry (1909-1957) considered himself a poet, and he composed an extensive poetic canon. No reliable edition of Lowry's poetry exists; increasing critical interest in all aspects of Lowry's life and work prompted the preparation of this complete edition of his poetry, in which the poems are located, identified, dated, arranged, collated, annotated, and explicated in biographical, critical, and textual introductions. The sections of Lowry's text are chronologically arranged to reflect his artistic development, and are preceded by short essays describing the specific issues raised by those poems. The opening section—Lowry's poetic juvenilia—reflects his fascination for the sea, as does the ensuing section, The Lighthouse Invites the Storm, his first collection of poetry, a sequence of related semi-autobiographical poems, which depicts the adventures of the characters Peter Gaunt and Vigil Forget. Lowry composed most of the Lighthouse in Mexico; following it in this edition is a small group of uncollected Mexican poems. The next two sections of text—"Dollarton 1940-54: Selected Poems 1947" and "Dollarton 1940-54: Uncollected Poems"—reflect and record the experience of Lowry's sojourn on the lower mainland, and its deep effect on him. A remarkably coherent group of love poems written between 1949 and Lowry's death in 1957 follows the Dollarton texts, and the appendices contain sections of song lyrics and undated fragments. This edition provides Lowryans with ready access to the latest determinable authorial versions of, and the textual histories for, the canon's four hundred and sixty-five poems, which range in date from 1925 to 1957.

description: A real-time path integral Monte Carlo approach is developed to study the dynamics in a many-body quantum system until reaching a nonequilibrium stationary state. The approach is based on augmenting an exact reduced equation for the evolution of the system in the interaction picture which is amenable to an efficient path integral (worldline) Monte Carlo approach. Results obtained for a model of inelastic tunneling spectroscopy reveal the applicability of the approach to a wide range of physically important regimes, including high (classical) and low (quantum) temperatures, and weak (perturbative) and strong electron-phonon couplings.

description: The gravitational shock waves have provided crucial insights into entanglement structures of black holes in the AdS/CFT correspondence. Recent progress on the soft hair physics suggests that these developments from holography may also be applicable to geometries beyond negatively curved spacetime. In this work, we derive a remarkably simple thermodynamic relation which relates the gravitational shock wave to a microscopic area deformation. Our treatment is based on the covariant phase space formalism and is applicable to any Killing horizon in generic static spacetime which is governed by arbitrary covariant theory of gravity. The central idea is to probe the gravitational shock wave, which shifts the horizon in the $u$ direction, by the Noether charge constructed from a vector field which shifts the horizon in the $v$ direction. As an application, we illustrate its use for the Gauss-Bonnet gravity. We also derive a simplified form of the gravitational scattering unitary matrix and show that its leading-order contribution is nothing but the exponential of the horizon area: $\mathcal{U}=\exp(i \text{Area})$.

description: When charged particles collide with a vacuum bubble, they can radiate strong electromagnetic waves due to rapid deceleration. Owing to the energy loss of the particles by this bremsstrahlung radiation, there is a non-negligible damping pressure acting on the bubble wall even when thermal equilibrium is maintained. In the non-relativistic region, this pressure is proportional to the velocity of the wall and could have influenced the bubble dynamics in the early universe.

Chronic nonadherence to therapeutic regimes : an in-depth analysis of male arthritis patients
Creators: name: Adam, Paul Marcel
Publisher: name: University of British Columbia
Year: 2010

description: Chronic nonadherence is the complete lack of adherence on the part of a patient to at least one aspect of their therapeutic regime for extended periods of time. Chronic nonadherence is similar to other forms of nonadherence in that it is a phenomena which is dangerous for patients, frustrating for practitioners, and costly to the health care system. However, unlike other forms of nonadherence, very little is known about this subject. In order to determine factors related to chronic nonadherence to a home exercise program, 15 male arthritis patients of varying ages underwent an in-depth structured interview. Eight of these patients were identified by the Arthritis Society as being chronic, treatment nonadherents. The other seven patients were randomly chosen from among the population of male arthritis patients in order to provide a comparison to the chronic nonadherent population. Ten variables were examined in this study in the hopes of determining factors related to chronic nonadherence. These variables were as follows: demographics, The Health Beliefs Model, patient's explanatory model, nature of the illness, satisfaction with practitioner attributes, shared responsibility, overall satisfaction, attitudes of significant others, use of unorthodox treatments, and problems with the home exercise program. Data analysis failed to produce any statistically significant findings, however the study did point to some interesting associations. One finding from this study is that nonadherence seems to be related to patient's Health Beliefs Models. Based on this finding the study then goes on to recommend an appropriate intervention which can be used by practitioners to enhance patient adherence. A second finding from this study is that a small number of the chronic nonadherent group were actually adherent to their home exercise programs. Several explanations have been provided as to how these patients might have been falsely labelled as chronic nonadherents.

description: We report here the discovery of two planet candidates as a result of our planet-search programme biased in favour of high-metallicity stars, using the ELODIE spectrograph at the Observatoire de Haute Provence. One of them has a minimum mass m_2\sin{i} = 2.5 M_Jup and is orbiting the metal-rich star HD43691 with period P = 40 days and eccentricity e = 0.14. The other planet has a minimum mass m_2\sin{i} = 5.6 M_Jup and orbits the slightly metal-rich star HD132406 with period P = 974 days and eccentricity e = 0.34. Both stars were followed up with additional observations using the new SOPHIE spectrograph that replaces the ELODIE instrument, allowing an improved orbital solution for the systems.

description: Entanglement is an essential ingredient for building a quantum network that can have many applications. Understanding how entanglement is distributed in a network is a crucial step to move forward. Here we study the conservation and distribution of Gaussian entanglement in a linear network using a new quantifier for bipartite entanglement. We show that the entanglement can be distributed through a beam-splitter in the same way as the transmittance and the reflectance. The requirements on the entangled states and the type of networks to satisfy this relation are presented explicitly. Our results provide a new quantification for quantum entanglement and further insights into the structure of entanglement in a network.

description: In spite of the relevance of Classical Cepheids as primary distance indicators, a general consensus on the dependence of the Period-Luminosity (PL) relation on the Cepheid chemical composition has not been achieved yet. From the theoretical point of view, our previous investigations were able to reproduce some empirical tests for suitable assumptions on the helium to metal relative enrichment, but those results relied on specific assumptions concerning the Mass-Luminosity relation and the efficiency of the convective transfer in the pulsating envelopes. In this paper, we investigate the effects of the assumed value of the mixing length parameter l/Hp on the pulsation properties and we release the assumption of a fixed Mass-Luminosity relation. As a whole, we show that our pulsation relations appear fully consistent with the observed properties of Galactic and Magellanic Cloud Cepheids, supporting the predicted steepening and brightening of the PL relations when moving from metal-rich to metal-poor variables. Moreover, we show that the distances inferred by the predicted PW relations agree with recently measured trigonometric parallaxes, whereas they suggest a correction to the values based on the Infrared Surface Brightness technique, as already found from an independent method. Finally, also the pulsation metal contents suggested by the predicted PW relations appear in statistical agreement with spectroscopic [Fe/H] measurements.

description: Counterfactual explanations (CEs) are a practical tool for demonstrating why machine learning classifiers make particular decisions. For CEs to be useful, it is important that they are easy for users to interpret. Existing methods for generating interpretable CEs rely on auxiliary generative models, which may not be suitable for complex datasets, and incur engineering overhead. We introduce a simple and fast method for generating interpretable CEs in a white-box setting without an auxiliary model, by using the predictive uncertainty of the classifier. Our experiments show that our proposed algorithm generates more interpretable CEs, according to IM1 scores, than existing methods. Additionally, our approach allows us to estimate the uncertainty of a CE, which may be important in safety-critical applications, such as those in the medical domain.

description: The Hamiltonian of a N-boson system confined on a ring with zero spin and repulsive interaction is diagonalized. The excitation of a pair of p-wave-particles rotating reversely appears to be a basic mode. The fluctuation of many of these excited pairs provides a mechanism of oscillation, the states can be thereby classified into oscillation bands. The particle correlation is studied intuitively via the two-body densities. Bose-clustering originating from the symmetrization of wave functions is found, which leads to the appearance of 1-, 2-, and 3-cluster structures. The motion is divided into being collective and relative, this leads to the establishment of a relation between the very high vortex states and the low-lying states.

description: Este trabalho analisa a obra "Totem" de André Vallias, explorando sua relevância como uma poesia visual e digital que reflete sobre as tensões da modernidade. Inspirado pelas vanguardas literárias brasileiras, em especial o concretismo, utilizando uma abordagem inovadora ao integrar recursos visuais e tecnológicos em sua poesia. Se destaca por sua crítica à fragmentação da identidade e à globalização, utilizando a forma poética como um meio de resistência cultural. A disposição gráfica das palavras e a inclusão de elementos digitais rompem com o modelo tradicional de leitura, exigindo do leitor uma postura ativa e reflexiva. A obra questiona as narrativas dominantes da sociedade contemporânea, promovendo uma análise crítica das estruturas de poder que moldam a vida cotidiana. Além disso, a utilização da tecnologia digital na construção do poema amplia as possibilidades de interação, transformando a obra em uma experiência sensorial que transcende o papel. Este estudo busca entender como Vallias, por meio de "Totem", não só dialoga com o concretismo, mas também o expande para o ambiente digital, criando novas formas de expressão e reflexão sobre a realidade contemporânea.

description: Aluminum monochloride (AlCl) has been proposed as an excellent candidate for laser cooling. Here we present absorption spectroscopy measurements on the $A^1Π\leftarrow X^1Σ^+$ transition in AlCl inside a cryogenic helium buffer-gas beam cell. The high resolution absorption data enables a rigorous, quantitative comparison with our high-level ab initio calculations of the electronic and rovibronic energies, providing a comprehensive picture of the AlCl quantum structure. The combination of high resolution spectral data and theory permits the evaluation of spectroscopic constants and associated properties, like equilibrium bond length, with an order of magnitude higher precision. Based on the measured molecular equilibrium constants of the $A^1Π$ state, we estimate a Franck-Condon factor of the $A^1Π\leftarrow X^1Σ^+$ of 99.88%, which confirms that AlCl is amenable to laser cooling.

description: An analysis of radiating perfect fluid models with asymptotically AdS boundary conditions is presented. Such scenarios consist of a spherical gas of radiation (a "star") localised near the centre of the spacetime due to the confining nature of the AdS potential. We consider the variation of the total mass of the star as a function of the central density, and observe that for large enough dimensionality, the mass increases monotonically with the density. However in the lower dimensional cases, oscillations appear, indicating that the perfect fluid model of the star is becoming unrealistic. We find the critical dimension separating these two regimes to be eleven.

description: The words we use to talk about the current epidemiological crisis on social media can inform us on how we are conceptualizing the pandemic and how we are reacting to its development. This paper provides an extensive explorative analysis of how the discourse about Covid-19 reported on Twitter changes through time, focusing on the first wave of this pandemic. Based on an extensive corpus of tweets (produced between 20th March and 1st July 2020) first we show how the topics associated with the development of the pandemic changed through time, using topic modeling. Second, we show how the sentiment polarity of the language used in the tweets changed from a relatively positive valence during the first lockdown, toward a more negative valence in correspondence with the reopening. Third we show how the average subjectivity of the tweets increased linearly and fourth, how the popular and frequently used figurative frame of WAR changed when real riots and fights entered the discourse.

description: En France, les pathologies de l’appareil locomoteur sont la 1ère cause de handicap rapportée par les personnes de plus de 40 ans. Les recommandations actuelles préconisent l’association de mesures médicamenteuses et non médicamenteuses. Cependant, seuls 30 à 50% des patients adhèrent au traitement à long terme. La cure thermale, en plus de ses effets spécifiques, pourrait offrir un cadre favorable à l’instauration de modifications pérennes et bénéfiques du mode de vie. Dans le cadre de cet article, nous avons choisi de ne traiter que la lombalgie chronique et l’arthrose des membres inférieurs. Nous avons réalisé une revue narrative critique de la littérature. La base de données MEDLINE a été interrogée via PubMed en janvier 2019. Dans la lombalgie chronique, la cure thermale améliore la douleur et la fonction à 3 et 6 mois et réduit la consommation médicamenteuse. Il n’a pas été démontré d’effet sur le retour au travail. Dans la gonarthrose, la cure thermale associée à des exercices à domicile améliore la douleur et la fonction à 3, 6 et 9 mois. Les mécanismes de ces effets sont multiples et pourraient être en partie médiés par des modifications cognitivo-comportementales positives favorisées par l’effet cure et par les thérapies éducatives et cognitivo-comportementales spécifiques instaurées au cours du séjour en milieu thermal. Les effets de la cure thermale sur l’adhésion aux traitements restent à évaluer.
description: In France, musculoskeletal disorders are the first cause of years lived with disability in people over 40 years. Current recommendations advocate the combination of pharmacological and non-pharmacological treatments. However, only 30 to 50% of patients adhere to the treatment in the long-term. Spa therapy, in addition to its specific effects, could provide a favorable environment for the introduction of beneficial and persistent lifestyle changes. In this article, we chose to focus only on chronic low back pain and lower limb osteoarthritis. We conducted a critical narrative review of the literature. The MEDLINE database was searched via PubMed in January 2019. In chronic low back pain, spa therapy improves pain and function at 3 and 6 months and reduces drug consumption. There is no evidence of effect on return to work. In knee osteoarthritis, spa therapy combined with home-based exercise improves pain and function at 3, 6 and 9 months. The mechanisms of these effects are multiple and could be partly mediated by positive cognitive-behavioral changes favored by the spa therapy and by the specific educational and cognitive-behavioral therapies introduced during spa therapy. The effects of spa therapy on adherence to treatments remain to be evaluated.

description: On the basis of the Fermi liquid theory, the Kadowaki-Woods ratio $A/γ^2$ is evaluated by using a first principle band calculation for typical itinerant $d$ and $f$ electron systems. It is found as observed that the ratio for the $d$ electron systems is significantly smaller than the normal $f$ systems, even without considering their relatively weak correlation. The difference in the ratio value comes from different characters of the Fermi surfaces. By comparing Pd and USn$_3$ as typical cases, we discuss the importance of the Fermi surface dependence of the quasiparticle transport relaxation.

We derive three integral fluctuation theorems (FTs) for these contributions and show that they lead to the following universal inequality: an arbitrary nonequilibrium transformation always produces a change in the total entropy production greater or equal than the one produced if the transformation is done very slowly (adiabatically). Previously derived fluctuation theorems can be recovered as special cases. We show how these FTs can be experimentally tested by performing the counting statistics of the electrons crossing a single level quantum dot coupled to two reservoirs with externally varying chemical potentials. The entropy probability distributions are simulated for driving protocols ranging from the adiabatic to the sudden switching limit.

description: Sentiment analysis (SA) systems, though widely applied in many domains, have been demonstrated to produce biased results. Some research works have been done in automatically generating test cases to reveal unfairness in SA systems, but the community still lacks tools that can monitor and uncover biased predictions at runtime. This paper fills this gap by proposing BiasRV, the first tool to raise an alarm when a deployed SA system makes a biased prediction on a given input text. To implement this feature, BiasRV dynamically extracts a template from an input text and from the template generates gender-discriminatory mutants (semantically-equivalent texts that only differ in gender information). Based on popular metrics used to evaluate the overall fairness of an SA system, we define distributional fairness property for an individual prediction of an SA system. This property specifies a requirement that for one piece of text, mutants from different gender classes should be treated similarly as a whole. Verifying the distributional fairness property causes much overhead to the running system. To run more efficiently, BiasRV adopts a two-step heuristic: (1) sampling several mutants from each gender and checking if the system predicts them as of the same sentiment, (2) checking distributional fairness only when sampled mutants have conflicting results. Experiments show that compared to directly checking the distributional fairness property for each input text, our two-step heuristic can decrease overhead used for analyzing mutants by 73.81% while only resulting in 6.7% of biased predictions being missed. Besides, BiasRV can be used conveniently without knowing the implementation of SA systems. Future researchers can easily extend BiasRV to detect more types of bias, e.g. race and occupation.

description: We present a cost-effective treatment of the triple excitation amplitudes in the time-dependent optimized coupled-cluster (TD-OCC) framework called TD-OCCDT(4) for studying intense laser-driven multielectron dynamics. It considers triple excitation amplitudes correct up to fourth-order in many-body perturbation theory and achieves a computational scaling of O(N7), with N being the number of active orbital functions. This method is applied to the electron dynamics in Ne and Ar atoms exposed to an intense near-infrared laser pulse with various intensities. We benchmark our results against the time-dependent complete-active-space self-consistent field (TD-CASSCF), time-dependent optimized coupled-cluster with double and triple excitations (TD-OCCDT), time-dependent optimized coupled-cluster with double excitations (TD-OCCD), and the time-dependent Hartree-Fock (TDHF) methods to understand how this approximate scheme performs in describing nonperturbatively nonlinear phenomena, such as field-induced ionization and high-harmonic generation. We find that the TD-OCCDT(4) method performs equally well as the TD-OCCDT method, almost perfectly reproducing the results of fully-correlated TD-CASSCF with a more favorable computational scaling.

description: We express the d=4, N=2 black hole effective potential for cubic holomorphic F functions and generic dyonic charges in terms of d=5 real special geometry data. The 4d critical points are computed from the 5d ones, and their relation is elucidated. For symmetric spaces, we identify the BPS and non-BPS classes of attractors and the respective entropies. These are related by simple formulae, interpolating between four and five dimensions, depending on the volume modulus and on the 4d magnetic (or electric) charges, and holding true also for generic field configurations and for non-symmetric cubic geometries.

description: We consider a design for a cyclic microrefrigerator using a superconducting flux qubit. Adiabatic modulation of the flux combined with thermalization can be used to transfer energy from a lower temperature normal metal thin film resistor to another one at higher temperature. The frequency selectivity of photonic heat conduction is achieved by including the hot resistor as part of a high frequency LC resonator and the cold one as part of a low-frequency oscillator while keeping both circuits in the underdamped regime. We discuss the performance of the device in an experimentally realistic setting. This device illustrates the complementarity of information and thermodynamic entropy as the erasure of the quantum bit directly relates to the cooling of the resistor.

Heinz Brandt – Ein streitbarer Intellektueller und die IG Metall
Creators: name: Andresen, Knud
Publisher: name: Moving the Social
Year: 2015

description: Heinz Brandt (1909–1986), a jewish-born socialist, worked since 1959 as editorial journalist for the “metall”, the official magazine for the members of the trade-union IG Metall. Brandts life and work is an example for a part of the labour movement, which tried to keep up the emancipatoric and even utopistic horizon of liberation from a capitalistic society. Brandt, who spent ten years in prison and concentration-camps in Nazi-Germany, fled from GDR in 1958. He was kidnapped in the GDR in 1961. An international campaign for his release had success in 1964.
After the release, Brandt tried to work for a human socialism, which was strongly inspired by his grand-cousin Erich Fromms ideas of a Being-society instead of a Having-Society. In the seventies he played a prominent role in the new social movements and in undogmatical leftwing critics in the trade unions, especially against the civil use of nuclear power. This prominence brought him in conflict with the trade union. This attitude was strongly noncompatible with the institutional character of the west-german trade union, nonetheless of the emancipatoric horizon, specially the IG Metall. As prominent trade unionist and active writer, he had power of discourse.

The Donbas Miners‘ Movement in the Very Late Soviet Era: An Historical Perspective
Creators: name: Siegelbaum, Lewis H.
Publisher: name: Moving the Social
Year: 2015

description: Beginning with some recollections about my own involvement with the miners‘ movement in Ukraine‘s Donbas basin, this essay critically reconsiders the analyses of the movement that I and others made in the late 1980s and for a number of years after the Soviet Union‘s collapse. It argues that the movement was a “transitional” phenomenon, asserting itself at a time when labor and its representation were no longer under Communist control but when the rule of capital had yet to assert itself. The strategic alliance that the movement made with enterprise directors grew out of the paternalistic nature of the Soviet enterprise and, after the collapse of the Soviet system, the intensification of dependency relations within it. The remainder of the essay engages with two analyses of the nature of the transition – Burawoy and Krotov‘s notion of the rise of merchant capital, and Kideckel‘s concept of “neo-capitalism” – in the light of post-independence Ukrainian politics and the progressive weakening of the miners‘ movement. It concludes that the shrinkage of tactical space for the insertion of mineworkers‘ objectives into national politics made it extremely unlikely that the movement could sustain its efforts on behalf of a „normal life“ for the dwindling number of miners and their families.

description: Understanding the processes occurring in the nuclear disk of our Galaxy is interesting in its own right, as part of the Milky Way Galaxy, but also because it is the closest galactic nucleus. It has been more than two decades since it was recognized that the general phenomenon of higher gas temperature in the inner few hundred parsecs by comparison with local clouds in the disk of the Galaxy. This is one of the least understood characteristics of giant molecular clouds having a much higher gas temperature than dust temperature in the inner few degrees of the Galactic center. We propose that an enhanced flux of cosmic-ray electrons, as evidenced recently by a number of studies, are responsible for directly heating the gas clouds in the nuclear disk, elevating the temperature of molecular gas ($\sim$ 75K) above the dust temperature ($\sim$ 20K). In addition we report the detection of nonthermal radio emission from Sgr B2-F based on low-frequency GMRT and VLA observations. The higher ionization fraction and thermal energy due to the impact of nonthermal electrons in star forming sites have important implications in slowing down star formation in the nuclear disk of our galaxy and nuclei of galaxies.

Female Workers but not Women: Paradoxes in Women’s Conditions and Strategies in Swedish Trade Unions, 1900–1925
Creators: name: Uppenberg, Carolina
Publisher: name: Moving the Social
Year: 2015

description: This article compares the opportunities that existed for trade union organisation by women and the scope for pursuing women’s issues in the Swedish Tailoring Workers’ Union (Skrädderiarbetareförbundet), the Swedish Textile Workers’ Union (Textilarbetareförbundet) and the Swedish Women’s Trade Union (Kvinnornas fackförbund). Trade union minutes are analysed using theories on women’s organisation, in which exposure of male standards in trade union organisation and the concept of women as powerless are central. The results reveal some differences in the opportunities for women to become members of the Tailoring Workers’ Union, which initially tried to exclude women, and the Textile Workers’ Union, which saw it as a priority to recruit more women. Nevertheless, both unions shared a similar view of women as weak and especially difficult to organise as trade union members. A lack of debate about women’s conditions is also clear in both unions. Comparison with the Women’s Trade Union shows that dedicated organisations for women played a major role in women’s opportunities for union involvement, but that gender-based union organisation was regarded as a threat to the supposedly genderless trade unions.
