description: COVID-19 has radically changed society as we know it. To reduce the spread of the virus, millions across the globe have been forced to work remotely, often in make-shift home offices, and using a plethora of new, unfamiliar digital technologies. In this article, we critically analyse cyber security and privacy concerns arising due to remote working during the coronavirus pandemic. Through our work, we discover a series of security risks emerging because of the realities of this period. For instance, lack of remote-working security training, heightened stress and anxiety, rushed technology deployment, and the presence of untrusted individuals in a remote-working environment (e.g., in flatshares), can result in new cyber-risk. Simultaneously, we find that as organisations look to manage these and other risks posed by their remote workforces, employee's privacy (including personal information and activities) is often compromised. This is apparent in the significant adoption of remote workplace monitoring, management and surveillance technologies. Such technologies raise several privacy and ethical questions, and further highlight the tension between security and privacy going forward.

Time-limited sex therapy for couples : a controlled evaluation of group and individual couple intervention
Creators: name: Nemetz, Georgia Helen
Publisher: name: University of British Columbia
Year: 2010

description: The effectiveness of a behaviourally based, broad band therapy for sexually dysfunctional couples was examined. Twenty-four couples were randomly assigned to either individual or group couple treatment. Treatment, identical for both conditions, consisted of: information and education; emphasis on mutual responsibility; attitude change skills training; communication facilitation; reduction of all forms of sexual anxiety and graduated behavioral homework assignments. Measures of treatment effectiveness were repeatedly taken during a two-week baseline, five weeks of treatment and at the ends of the three week and three month follow-up periods. These measures included the Sexual Behavior Index, the Sexual Arousal Inventory and the Sexual Satisfaction Index. The six couples randomly assigned to the control condition were subjected to identical measurement without the benefit of treatment. Increases in arousal, satisfaction and behavior were evidenced for both treatment groups; however a trend towards increased generalization and maintenance of improvement was evidenced for those receiving group treatment. Improvement was maintained through the three month follow-ups. Control clients showed no improvement and evidenced trends towards deterioration. The results of the present study document the efficacy of the short term behaviorally based program and indicate the viability of the group format as a cost-effective alternative to individual intervention.
Glauber gluons in annihilation amplitudes for heavy meson decays

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We investigate the Glauber divergences in nonfactorizable annihilation amplitudes for two-body hadronic heavy meson decays in the $k_T$ factorization theorem at one-loop level. These divergences can be absorbed into the Glauber factors in the dominant kinematic regions of small parton momenta, which modify the interference between a nonfactorizable annihilation amplitude and other amplitudes by rotating it with a phase. We postulate that only the Glauber effect associated with a pion is significant, due to its special role as a $q\bar q$ bound state and as a pseudo Nambu-Goldstone boson simultaneously. It is elaborated that the data of the $D\toππ$ and $πK$ branching ratios have revealed prominent Glauber effects. This work provides a solid theoretical ground for the factorization-assisted topological-amplitude parametrization of two-body hadronic $D$ meson decays.

We construct a compact state space and identify past and future attractors of the system and recover a previously discovered future attractor corresponding to an expanding accelerating model. We also discuss the existence of universes which have both a past and future bounce, a phenomenon which is absent in General Relativity.

description: Star formation in half of massive galaxies was quenched by the time the Universe was three billion years old. Very low amounts of molecular gas appear responsible for this, at least in some cases, though morphological gas stabilization, shock heating, or activity associated with accretion onto a central supermassive black hole is invoked in other cases. Recent studies of quenching by gas depletion have been based upon upper limits that are insufficiently sensitive to determine this robustly, or stacked emission with its problems of averaging. Here we report 1.3mm observations of dust emission from six strongly lensed galaxies where star formation has been quenched, with magnifications of up to a factor of 30. Four of the six galaxies are undetected in dust emission, with an estimated upper limit on the dust mass of 0.0001 times the stellar mass, and by proxy (assuming a Milky Way molecular gas-to-dust ratio) 0.01 times the stellar mass in molecular gas. This is two orders of magnitude less molecular gas per unit stellar mass than seen in star forming galaxies at similar redshifts. It remains difficult to extrapolate from these small samples, but these observations establish that gas depletion is responsible for a cessation of star formation in some fraction of high-redshift galaxies.

Secular dynamics of coplanar, non-resonant planetary system under the general relativity and quadrupole moment perturbations

description: We construct a secular theory of a coplanar system of N-planets not involved in strong mean motion resonances, and which are far from collision zones. Besides the point-to-point Newtonian mutual interactions, we consider the general relativity corrections to the gravitational potential of the star and the innermost planet, and also a modification of this potential by the quadrupole moment and tidal distortion of the star. We focus on hierarchical planetary systems. A survey regarding model parameters (the masses, semi-major axes, spin rate of the star) reveals a rich and non-trivial dynamics of the secular system. Our study is focused on its equilibria. Such solutions predicted by the classic secular theory, which correspond to aligned (mode I) or anti-aligned (mode II) apsides, may be strongly affected by the gravitational corrections. The so called true secular resonance, which is a new feature of the classic two-planet problem discovered by Michtchenko & Malhotra (2004), may appear in other, different regions of the phase space of the generalized model. We found bifurcations of mode II which emerge new, yet unknown in the literature, secularly unstable equilibria and a complex structure of the phase space. These equilibria may imply secularly unstable orbital configurations even for nitially moderate eccentricities. The point mass gravity corrections can affect the long term-stability in the secular time scale, which may directly depend on the age of the host star through its spin rate. We also analyze the secular dynamics of the upsilon Andromede system in the realm of the generalized model. Also in this case of the three-planet system, new secular equilibria may appear.

description: We investigate classical Heisenberg spins on the Shastry-Sutherland lattice and under an external magnetic field. A detailed study is carried out both analytically and numerically by means of classical Monte-Carlo simulations. Magnetization pseudo-plateaux are observed around 1/3 of the saturation magnetization for a range of values of the magnetic couplings. We show that the existence of the pseudo-plateau is due to an entropic selection of a particular collinear state. A phase diagram that shows the domains of existence of those pseudo-plateaux in the $(h, T)$ plane is obtained.

description: The Matthew effect refers to the adage written some two-thousand years ago in the Gospel of St. Matthew: "For to all those who have, more will be given." Even two millennia later, this idiom is used by sociologists to qualitatively describe the dynamics of individual progress and the interplay between status and reward. Quantitative studies of professional careers are traditionally limited by the difficulty in measuring progress and the lack of data on individual careers. However, in some professions, there are well-defined metrics that quantify career longevity, success, and prowess, which together contribute to the overall success rating for an individual employee. Here we demonstrate testable evidence of the age-old Matthew "rich get richer" effect, wherein the longevity and past success of an individual lead to a cumulative advantage in further developing his/her career. We develop an exactly solvable stochastic career progress model that quantitatively incorporates the Matthew effect, and validate our model predictions for several competitive professions. We test our model on the careers of 400,000 scientists using data from six high-impact journals, and further confirm our findings by testing the model on the careers of more than 20,000 athletes in four sports leagues. Our model highlights the importance of early career development, showing that many careers are stunted by the relative disadvantage associated with inexperience.

description: The generalized quantum master equation with transport particle number resolution, like its conventional unconditioned counterpart, has also the time-local and time-nonlocal prescriptions.The latter is found to be more suitable for the effect of electrodes bandwidth on quantum transport and noise spectrum for weak system-reservoir coupling, as calibrated with the exact results in the absence of Coulomb interaction. We further analyze the effect of Coulomb interaction on the noise spectrum of transport current through quantum dot systems, and show that the realistic finite Coulomb interaction and finite bandwidth are manifested only with non-Markovian treatment. We demonstrate a number of non-Markovian characteristics of shot noise spectrum, including that due to finite bandwidth and that sensitive to and enhanced by the magnitude of Coulomb interaction.

The Hierarchy of Countries in the Contemporary Art World and Market.
Creators: name: Quemin, Alain
Publisher: name: Austrian Journal of Historical Studies
Year: 2006

description: Although studies on globalisation have multiplied since the 1990s there are still rather few empirical sociological studies in this area of interest. Drawing upon the case of contemporary visual arts, this paper tries to highlight how discourses widespread within the art world on globalization, métissage and the abolition of boundaries are largely due to illusion. When objectifying the positions occupied by different countries in the artistic domain a very marked hierarchy becomes apparent. This hierarchy reveals that beyond the development of international exchange there subsist on the one hand a centre with well-defined outlines consisting of some Western countries (the United States and Germany taking the best places) and on the other hand a vast periphery, consisting of all the countries that do not belong to the first set.

description: We present molecular dynamics simulations of a simple model for polymer melts with intramolecular barriers. We investigate structural relaxation as a function of the barrier strength. Dynamic correlators can be consistently analyzed within the framework of the Mode Coupling Theory (MCT) of the glass transition. Control parameters are tuned in order to induce a competition between general packing effects and polymer-specific intramolecular barriers as mechanisms for dynamic arrest. This competition yields unusually large values of the so-called MCT exponent parameter and rationalize qualitatively different observations for simple bead-spring and realistic polymers. The systematic study of the effect of intramolecular barriers presented here also establishes a fundamental difference between the nature of the glass transition in polymers and in simple glass-formers.

In the paper, the force will be defined from the energy and torque in a new way, which involves the gravitational force, electromagnetic force, inertial force, gradient of energy, and some other new force terms etc. One of these new force terms can be used to explain why the solar wind varies velocity along the magnetic force line in the interplanetary space between the sun and the earth.

description: The maximal symmetry of a quantum system with Heisenberg commutation relations is given by the projective representations of the automorphism group of the Weyl-Heisenberg algebra. The automorphism group is the central extension of the inhomogeneous symplectic group with a conformal scaling that acts on extended phase space. We determine the subgroup that also leaves invariant a degenerate orthogonal Minkowski line element. This defines noninertial relativistic symmetry transformations that have the expected classical limit as c becomes infinite.

description: Resumo O presente projeto de pesquisa visa contribuir para o entendimento da evolução tectônica e geodinâmica da porção sudoeste de Gondwana, desde sua amalgamação no Neoproterozoico ao seu rifteamento no Cretáceo. Para tal, a pesquisa tem como foco a atividade tectônica de longo prazo em um conjunto de zonas de cisalhamento do Cinturão Kaoko, no noroeste da Namíbia, e sua correlação com estruturas equivalentes no continente Sul-Americano. A história deformacional dessas estruturas durante a orogênese Brasiliana/Pan-africana está sendo reconstruída usando uma combinação de métodos geocronológicos de alta e média temperatura em amostras selecionadas de acordo com uma análise estrutural detalhada em escala de campo e microscópica. Um segundo objetivo do projeto, no qual esta apresentação é focada, é avaliar o impacto da reativação rúptil destas mesmas zonas de cisalhamento durante a evolução Fanerozoica da área, em particular durante o longo período entre a orogênese Neoproterozoica e a abertura do Oceano Atlântico no Cretáceo. Para tal, a evolução térmica dos terrenos delimitados pelas principais zonas de cisalhamentos do cinturão está sendo reconstruída por meio de análise termocronológica (U-Th)/He de detalhe em zircão e apatita. Resultados preliminares indicam um soerguimento rápido pós-orogênico ao longo de todo o cinturão, e contrastes entre as trajetórias temperatura-tempo dos principais terrenos do cinturão sugerem um possível comportamento em bloco, controlado pela reativação rúptil das principais zonas de cisalhamento durante o Paleozoico. Os modelos térmicos gerados estão sendo detalhados por meio de um trabalho metodológico que visa integrar novas formas de estimar a retenção de He em zircão a partir da caracterização do grau de metamitização dos cristais utilizando a espectroscopia Raman. Os resultados preliminares apresentados nesta contribuição permitem reconhecer correlações entre as idades (U-Th)/He aparentes e a largura e posição dos principais picos no espectro Raman nos cristais analisados, e sugerem que uma quantificação da heterogeneidade do material datado pode contribuir para aprimorar a interpretação e modelagem dos resultados termocronológicos.

description: Atrophy of the alveolar crest in the posterior maxilla is related to lower implant survival rates. The problem is exacerbated by clinically occurring thin cortical bone. FEM allows to simulate adequately biomechanics properties of the bone-implant interface with their wide scattering and dependence on age, sex, etc. The method is suitable for evaluating the effect of the maxilla cortical bone elasticity and quality as well as implant diameter on its bearing ability The aim was to evaluate bone stress magnitudes and introduce innovative indices of implant load-bearing capacity to assess bone capability to successfully withstand functional loading under poor bone quality conditions. 3D models of osseointegrated implant placed crestally in type III/IV bone, were analyzed in FEM with cortical bone variable elasticity modulus and ultimate strength. Maximal von Mises stresses in surrounding bone were calculated and compared with patient-specific cortical bone ultimate strength to determine the taplant index of load-bearing capacity. Its value was influenced by implant diameter cortkal bone elasticity and bone quality.

description: In this paper we study the determinants of starless core temperatures in the Perseus molecular cloud. We use NH3 (1,1) and (2,2) observations to derive core temperatures (T_kin) and data from the COMPLETE Survey of Star Forming Regions and the c2d Spitzer Legacy Survey for observations of the other core and molecular cloud properties. The kinetic temperature distribution probed by NH3 is in the fairly narrow range of 9 - 15 K. We find that cores within the clusters IC348 and NGC1333 are significantly warmer than "field" starless cores, and T_kin is higher within regions of larger extinction-derived column density. Starless cores in the field are warmer when they are closer to class O/I protostars, but this effect is not seen for those cores in clusters. For field starless cores, T_kin is higher in regions in which the 13CO linewidth and the 1.1mm flux from the core are larger, and T_kin is lower when the the peak column density within the core and average volume density of the core are larger. There is no correlation between T_kin and 13CO linewidth, 1.1mm flux, density or peak column density for those cores in clusters. The temperature of the cloud material along the line of sight to the core, as measured by CO or far-infrared emission from dust, is positively correlated with core temperature when considering the collection of cores in the field and in clusters, but this effect is not apparent when the two subsamples of cores are considered separately.

description: Using the Galaxy as an example, we study the effect of j x B force on the rotational curves of gas and plasma in galaxies. Acceptable model for the galactic magnetic field and plausible physical parameters are used to fit the flat rotational curve for gas and plasma based on the observed baryonic (visible) matter distribution and j x B force term in the static MHD equation of motion. We also study the effects of varied strength of the magnetic field, its pitch angle and length scale on the rotational curves. We show that j x B force does not play an important role on the plasma dynamics in the intermediate range of distances 6-12 kpc from the centre, whilst the effect is sizable for larger r (r > 15 kpc), where it is the most crucial.

description: An adiabatic cycle around a degeneracy point in the parameter space of a one-dimensional band insulator is known to result in an integer valued noiseless particle transport in the thermodynamic limit. Recently, it was shown that in the case of an infinite bipartite lattice the adiabatic Thouless protocol can be continuously deformed into a fine tuned finite-frequency cycle preserving the properties of noiseless quantized transport. In this paper, we numerically investigate the implementation of such an ideal rapid-cycle Thouless pumping protocol in a one-dimensional optical lattice. It is shown that the rapidity will cause first order corrections due to next-to-nearest-neighbour hopping and second order corrections due to the addition of a harmonic potential. Lastly, the quantization of the change in center of mass of the particle distribution is investigated, and shown to have corrections in the first order of the potential curvature.

Then we apply this result to the equivariant cohomology theory of flag varieties.

description: We study four dimensional gravity with a negative cosmological constant deformed by the Nieh-Yan torsional topological invariant with a spacetime-dependent coefficient. We find an exact solution of the Euclidean system, which we call the torsion vortex, having two asymptotic AdS4 regimes supported by a pseudoscalar with a kink profile. We propose that the torsion vortex is the holographic dual of a three dimensional system that exhibits distinct parity breaking vacua. The torsion vortex represents a (holographic) transition between these distinct vacua. We expect that from the boundary point of view, the torsion vortex represents a `domain wall' between the two distinct vacua. From a bulk point of view, we point out an intriguing identification of the parameters of the torsion vortex with those of an Abrikosov vortex in a Type I superconductor. Following the analogy, we find that external Kalb-Ramond flux then appears to support bubbles of flat spacetime within an asymptotically AdS geometry.

A social media outlook on branding higher education institutions in Africa
Creators: name: Fomunyam, Dr. Kehdinga George

description: The rise in popularity of branding and social media is changing the landscape in consumer marketing. This shift has also affected how higher education institutions build relationships with their stakeholders. With the proliferation of online degree options, distance is less of a consideration in choosing a school and thus institutions are aiming for global visibility and a wider reach. This study explores how branding and social media engagement impacts relationship quality between the university and prospective students, current students and the society at large. It also examines how consistent and targeted branding can increase student numbers. Data collected from institutions across Africa was analysed to determine if a correlation exists between branding and increase in student enrolment in higher institutions in Africa. The study focuses on the common digital and social media marketing utilized by universities across Africa and identifies the purpose of using digital and social media marketing by higher education institutions (HEIs). Furthermore, it also assessed the level of adoption of digital technologies. This study suggests the exploration of market segmentation as a means of meeting the needs of prospective students and increasing visibility and desirability.
Phase of the Fermion Determinant for QCD at Finite Chemical Potential

description: In this lecture we discuss various properties of the phase factor of the fermion determinant for QCD at nonzero chemical potential. Its effect on physical observables is elucidated by comparing the phase diagram of QCD and phase quenched QCD and by illustrating the failure of the Banks-Casher formula with the example of one-dimensional QCD. The average phase factor and the distribution of the phase are calculated to one-loop order in chiral perturbation theory. In quantitative agreement with lattice QCD results, we find that the distribution is Gaussian with a width $\sim μT \sqrt V$ (for $m_π\ll T \ll Λ_{\rm QCD}$). Finally, we introduce, so-called teflon plated observables which can be calculated accurately by Monte Carlo even though the sign problem is severe.
