#MeToo, popular feminism and the news: A content analysis of UK newspaper coverage

This article examines the first 6 months of #MeToo’s coverage in the UK press, revealing how newspapers played an important role in heightening the campaign’s visibility. Using content analysis, our study demonstrates that the press contributed to expanding and reinforcing #MeToo’s visibility in important ways. In terms of reach, the UK press has expanded the movement’s visibility beyond social media, addressing potentially new and different readerships. This attests to the pivotal role that news media continue to play in disseminating global issues and debates for a national audience. Second, in terms of content, while the news coverage developed and consolidated stories that were originally revealed on social media, it also publicized new stories. However, our study also highlights how the press’ role in enabling and expanding the visibility of #MeToo has been characterized by a number of crucial and, we argue, problematic factors. First, while #MeToo was covered positively in all newspapers, there was significant variation within newspapers, which was largely consistent with their traditional ideological alignments. Second, the #MeToo coverage seems to have followed and reinforced familiar patterns with respect to news coverage of both sexual violence and feminism, namely, support of feminism alongside a concurrent de-politicization, an individualizing tendency through a focus on celebrity and the cultural industries, and the centring of the experiences of celebrity female subjects who are predominately White and wealthy

Characterization of PECVD Silicon Nitride Photonic Components at 532 and 900 nm Wavelength

Low temperature PECVD silicon nitride photonic waveguides have been fabricated by both electron beam lithography and 200 mm DUV lithography. Propagation losses and bend losses were both measured at 532 and 900 nm wavelength, revealing sub 1dB/cm propagation losses for cladded waveguides at both wavelengths for single mode operation. Without cladding, propagation losses were measured to be in the 1-3 dB range for 532 nm and remain below 1 dB/cm for 900 nm for single mode waveguides. Bend losses were measured for 532 nm and were well below 0.1 dB per 90 degree bend for radii larger than 10 mu m

Transport of malic acid in the yeast Schizosaccharomyces pombe: evidence for a proton-dicarboxylate symport

The transport system for malic acid present in Schizosaccharomyces pombe cells, growing in batch culture on several corbon sources, has been studied. It was found that the diarboxylic acid carrier of S. pombe is a proton-dicarboxylate symporter that allows transport and accumulation as a function of pH with the following kinetic parameters at pH 5·0: Vmax = 0·01 nmol of total malic acids 1 mg (dry weight) of cells, 1and Km = 0·1mM total malic acid uptake (pH 5·0) was accompanied by disappearance of extracellular protons, the uptake rates of which followed Michaelis-Menten kinetics as a function of the acid concentration. The Km values, calculated as the concentrations either of anions or of undissociated acid, at various extracellular pH values, pointed to the monoanionic form as the transported species. Furthermore, accumulated free acid suffered rapid efflux after the addition of the portonophore carbonyl cyanid m-chlorophenyl hydrazone. These results suggested that the transport system was a dicarboxylateproton symporter. Growth of cells in a medium with glucose (up to 14%, w/v) and malic acid (1·5%, w/v) also resulted in proton-dicarboxylate activity, suggesting that the system, besides being constitutive, was still active at high glucose concentrations. The following dicarboxylic acids acted as competitive inhibitors of malic acid transport at pH 5·0: D- malic acid, succinic acid, fumaric acid oxaloacetic acid, -Ketoglutaric acid, maleic acid, maleic and malonic acid. In addition all of these dicarboxylic acids induced proton movements that followed MichaelisMenten kinetics. It was concluded that the malic negatively charged form (probably the monoanionic form) was transported by a proton-symport mechanism and that the carrier appeared to be a common dicarboxylat transport sysmem. The undissociated acid entered the cells slowly by simple diffusion.(undefined

Universal cloning of continuous quantum variables

The cloning of quantum variables with continuous spectra is analyzed. A universal - or Gaussian - quantum cloning machine is exhibited that copies equally well the states of two conjugate variables such as position and momentum. It also duplicates all coherent states with a fidelity of 2/3. More generally, the copies are shown to obey a no-cloning Heisenberg-like uncertainty relation.Comment: 4 pages, RevTex.

From carewashing to radical care: the discursive explosions of care during Covid-19

Care, in all its permutations, is the buzzword of the moment, its meanings draining away in its constant evocation. Here, we briefly expand on older and newer meanings of care in the wake of Covid-19. These include the increasingly blurred boundaries between what has been traditionally understood as “care work” versus “essential work”; desperate attempts by corporations to promote themselves as ‘caring’; and the adoption of reactionary rather than progressive models of ‘care’ by populist leaders such as Trump, Johnson, and Bolsonaro. We then argue that we are in urgent need of a politics that recognises our mutual interdependence and vulnerability. Rejecting the extensive carelessness so evident today, our model of ‘universal care’ calls for inventive forms of collective care at every scale of life. We envisage a world in which genuine care is everywhere —from our most intimate ties to our relationship with the planet itself

The effect of induced sadness and moderate depression on attention networks

This study investigates how sadness and minor/moderate depression influences the three functions of attention: alerting, orienting, and executive control using the attention network test. The aim of the study is to investigate whether minor to moderate depression is more similar to sadness or clinical depression with regards to attentional processing. It was predicted that both induced sadness and minor to moderate depression will influence executive control by narrowing spatial attention and in turn this will lead to less interference from the flanker items (i.e., less effects of congruency) due to a focused attentional state. No differences were predicted for alerting or orienting functions. The results from the two experiments, the first inducing sadness (Experiment 1) and the second measuring subclinical depression (Experiment 2), show that, as expected, participants who are sad or minor to moderately depressed showed less flanker interference compared to participants who were neither sad nor depressed. This study provides strong evidence, that irrespective of its aetiology, sadness and minor/moderate depression have similar effects on spatial attention

Low forced expiratory volume is associated with blunted cardiac reactions to acute psychological stress in a community sample of middle-aged men and women

It has been argued recently that blunted cardiovascular reactions to acute psychological stress have adverse behavioural and health corollaries that reflect dysregulation of the neural systems that support motivation. We examined the association between cardiovascular reactions to a standard stress task, the paced auditory serial arithmetic rest, and forced expiratory volume in one second, an effort, hence motivation, dependent assessment of lung function measured by spirometry. Low forced expiratory volume, expressed as a ratio to height squared was associated with blunted heart rate, but not blood pressure, stress reactivity, r = .17, p < .001. The association survived adjustment for smoking, a range of anthropometric and sociodemographic covariates, resting heart rate and stress task performance, β = .11, p = .005. As such, our results provide support for the hypothesis that blunted stress reactivity may be a peripheral marker of a dysfunction in the brain systems that support motivated behaviour

Emergence of Anti-Cancer Drug Resistance: Exploring the Importance of the Microenvironmental Niche via a Spatial Model

Practically, all chemotherapeutic agents lead to drug resistance. Clinically, it is a challenge to determine whether resistance arises prior to, or as a result of, cancer therapy. Further, a number of different intracellular and microenvironmental factors have been correlated with the emergence of drug resistance. With the goal of better understanding drug resistance and its connection with the tumor microenvironment, we have developed a hybrid discrete-continuous mathematical model. In this model, cancer cells described through a particle-spring approach respond to dynamically changing oxygen and DNA damaging drug concentrations described through partial differential equations. We thoroughly explored the behavior of our self-calibrated model under the following common conditions: a fixed layout of the vasculature, an identical initial configuration of cancer cells, the same mechanism of drug action, and one mechanism of cellular response to the drug. We considered one set of simulations in which drug resistance existed prior to the start of treatment, and another set in which drug resistance is acquired in response to treatment. This allows us to compare how both kinds of resistance influence the spatial and temporal dynamics of the developing tumor, and its clonal diversity. We show that both pre-existing and acquired resistance can give rise to three biologically distinct parameter regimes: successful tumor eradication, reduced effectiveness of drug during the course of treatment (resistance), and complete treatment failure

Toll-Like Receptors 2 and 4 Regulate the Frequency of IFNγ-Producing CD4+ T-Cells during Pulmonary Infection with Chlamydia pneumoniae

TLR2 and TLR4 are crucial for recognition of Chlamydia pneumoniae in vivo, since infected TLR2/4 double-deficient mice are unable to control the infection as evidenced by severe loss of body weight and progressive lethal pneumonia. Unexpectedly, these mice display higher pulmonary levels of the protective cytokine IFNγ than wild type mice. We show here, that antigen-specific CD4+ T-cells are responsible for the observed IFNγ-secretion in vivo and their frequency is higher in TLR2/4 double-deficient than in wild type mice. The capacity of TLR2/4 double-deficient dendritic cells to re-stimulate CD4+ T-cells did not differ from wild type dendritic cells. However, the frequency of CD4+CD25+Foxp3+ T-cells was considerably higher in wild type compared to TLR2/4 double-deficient mice and was inversely related to the number of IFNγ-secreting CD4+ effector T-cells. Despite increased IFNγ-levels, at least one IFNγ-mediated response, protective NO-secretion, could not be induced in the absence of TLR2 and 4. In summary, CD4+CD25+Foxp3+ regulatory T-cells fail to expand in the absence of TLR2 and TLR4 during pulmonary infection with C. pneumoniae, which in turn enhances the frequency of CD4+IFNγ+ effector T-cells. Failure of IFNγ to induce NO in TLR2/4 double-deficient cells represents one possible mechanism why TLR2/4 double-deficient mice are unable to control pneumonia caused by C. pneumoniae and succumb to the infection
