Is Dealing with Climate Change a Corporation’s Responsibility? A Social Contract Perspective
In this paper, we argue that individuals – as members of society – play an important role in the expectations of whether or not companies are responsible for addressing environmental issues, and whether or not governments should regulate them. From this perspective of corporate social responsibility as a social contract we report the results of a survey of 1066 individuals. The aim of the survey was to assess participants’ belief in anthropogenic climate change, free-market ideology, and beliefs around who is responsible for dealing with climate change. Results showed that both climate change views and free market ideology have a strong effect on beliefs that companies are responsible for dealing with climate change and on support for regulatory policy to that end. Furthermore, we found that free market ideology is a barrier in the support of corporate regulatory policy. The implications of these findings for research, policy, and practice are discussed
Affective state influences retrieval-induced forgetting for integrated knowledge
Selectively testing parts of learned materials can impair later memory for nontested materials. Research has shown that such retrieval-induced forgetting occurs for low-integrated materials but may be prevented for high-integrated materials. However, previous research has neglected one factor that is ubiquitous in real-life testing: affective stat
A new bound on axion-like particles
Axion-like particles (ALPs) and photons can quantum mechanically interconvert
when propagating through magnetic fields, and ALP-photon conversion may induce
oscillatory features in the spectra of astrophysical sources. We use deep (370
ks), short frame time Chandra observations of the bright nucleus at the centre
of the radio galaxy M87 in the Virgo cluster to search for signatures of light
ALPs. The absence of substantial irregularities in the X-ray power-law spectrum
leads to a new upper limit on the photon-ALP coupling, : using a
conservative model of the cluster magnetic field consistent with Faraday
rotation measurements from M87 and M84, we find GeV at 95% confidence level for ALP masses eV. Other consistent magnetic field models lead to stronger limits of
-- GeV. These bounds are
all stronger than the limit inferred from the absence of a gamma-ray burst from
SN1987A, and rule out a substantial fraction of the parameter space accessible
to future experiments such as ALPS-II and IAXO
Cluster J Mycobacteriophages: Intron Splicing in Capsid and Tail Genes
Bacteriophages isolated on Mycobacterium smegmatis mc2155 represent many distinct genomes sharing little or no DNA sequence similarity. The genomes are architecturally mosaic and are replete with genes of unknown function. A new group of genomes sharing substantial nucleotide sequences constitute Cluster J. The six mycobacteriophages forming Cluster J are morphologically members of the Siphoviridae, but have unusually long genomes ranging from 106.3 to 117 kbp. Reconstruction of the capsid by cryo-electron microscopy of mycobacteriophage BAKA reveals an icosahedral structure with a triangulation number of 13. All six phages are temperate and homoimmune, and prophage establishment involves integration into a tRNA-Leu gene not previously identified as a mycobacterial attB site for phage integration. The Cluster J genomes provide two examples of intron splicing within the virion structural genes, one in a major capsid subunit gene, and one in a tail gene. These genomes also contain numerous free-standing HNH homing endonuclease, and comparative analysis reveals how these could contribute to genome mosaicism. The unusual Cluster J genomes provide new insights into phage genome architecture, gene function, capsid structure, gene mobility, intron splicing, and evolution. © 2013 Pope et al
Spatially Resolved On-Chip Picosecond Pulse Detection Using Graphene
We present an on-chip time domain terahertz (TD-THz) system in which picosecond pulses are generated in low-temperature-grown gallium arsenide (LT-GaAs) and detected in graphene. The detected pulses were found to vary in amplitude, full width at half maximum (FWHM), and DC offset when sampled optically at different locations along a 50-μm-long graphene photoconductive (PC) detector. The results demonstrate the importance of detection location and switch design in graphene-based on-chip PC detectors
Intertranslatability, Theoretical Equivalence, and Perversion
I investigate syntactic notions of theoretical equivalence between logical theories and an recent objection thereto. I show that this recent criticism of syntactic accounts as extensionally inadequate is unwarranted by developing an account which is plausibly extensionally adequate and more philosophically motivated. This is important for recent anti-exceptionalist treatments of logic since syntactic accounts require less theoretical baggage than semantic accounts
