Debating Shusenjo - the main battlefield of the comfort women issue: director Miki Dezaki in conversation with Mark R. Frost and Edward Vickers
This Asia-Pacific Journal: Japan Focus special issue on “The Comfort Women as Public History” concludes with documentary filmmaker Miki Dezaki in conversation with Edward Vickers and Mark R. Frost. Dezaki’s film Shusenjo, released in 2018, examines the controversy over “comfort women” within Japan, as well as its implications for Korea-Japan relations. Dezaki, himself Japanese-American, also devotes considerable attention to the growing ramifications of this controversy within the United States, as an instance of the increasing international significance of the comfort women issue. In this discussion, he, Frost and Vickers reflect on the messages of the film, the experience of making and distributing it, and what this reveals about the difficulty-and importance-of doing public history in a manner that respects the complexity of the past
On the Geroch-Traschen class of metrics
We compare two approaches to semi-Riemannian metrics of low regularity. The maximally 'reasonable' distributional setting of Geroch and Traschen is shown to be consistently contained in the more general setting of nonlinear distributional geometry in the sense of Colombea

Effects of the glial modulator palmitoylethanolamide on chronic pain intensity and brain function.
Background: Chronic neuropathic pain (NP) is a complex disease that results from damage or presumed damage to the somatosensory nervous system. Current treatment regimens are often ineffective. The major impediment in developing effective treatments is our limited understanding of the underlying mechanisms. Preclinical evidence suggests that glial changes are crucial for the development of NP and a recent study reported oscillatory activity differences within the ascending pain pathway at frequencies similar to that of cyclic gliotransmission in NP. Furthermore, there is evidence that glial modifying medications may be effective in treating NP. The aim of this Phase I open-label clinical trial is to determine whether glial modifying medication palmitoylethanolamide (PEA) will reduce NP and whether this is associated with reductions in oscillatory activity within the pain pathway. Methods: We investigated whether 6 weeks of PEA treatment would reduce pain and infra-slow oscillatory activity within the ascending trigeminal pathway in 22 individuals (17 females) with chronic orofacial NP. Results: PEA reduced pain in 16 (73%) of the 22 subjects, 11 subjects showed pain reduction of over 20%. Whilst both the responders and non-responders showed reductions in infra-slow oscillatory activity where orofacial nociceptor afferents terminate in the brainstem, only responders displayed reductions in the thalamus. Furthermore, functional connections between the brainstem and thalamus were altered only in responders. Conclusion: PEA is effective at relieving NP. This reduction is coupled to a reduction in resting oscillations along the ascending pain pathway that are likely driven by rhythmic astrocytic gliotransmission

Comparison of photoexcited p-InAs THz radiation source with conventional thermal radiation sources
P-type InAs excited by ultrashort optical pulses has been shown to be a strong emitter of terahertz radiation. In a direct comparison between a p-InAs emitter and conventional thermal radiationsources, we demonstrate that under typical excitation conditions p-InAs produces more radiation below 1.2 THz than a globar. By treating the globar as a blackbody emitter we calibrate a siliconbolometer which is used to determine the power of the p-InAs emitter. The emitted terahertz power was found to be 98±10 nW in this experiment
Far Infrared Spectroscopy of CsNiCl₃ Type Crystals
A far infrared interferometer has been interfaced to a microcomputer and programs developed to enable fourier transform spectroscopy to be carried out in real time.
A Heᶾ cooled bolometer-superconducting magnet system has been constructed for far infrared Zeeman spectroscopy. The bolometer element is magnetically shielded from the field using superconducting lead.
The theory of the transmission of polarized radiation through slabs of non-isotropic dielectric crystals mounted on a dielectric substrate is developed. The resulting equations allow general features of far infrared transmission spectra to be examined. For example they show that for "thicker" crystals, the transverse optical mode absorption lines are asymmetric while the longitudinal optical mode absorption lines are symmetric. For large angles of incidence, an extra absorption line is predicted to occur above the longitudinal optic mode frequency for crystals of low dielectric constant.
The infrared-active phonon spectra of thirteen crystals of the CsNiCl₃ type structure are reported and assigned to specific lattice modes.
Using polarized, Zeeman spectroscopy, two magnon lines are identified in the quasi 1 dimensional antiferromagnet RbCoBr₃ at 100.0±0.5 cm⁻¹ and 120.0±0.5 cm⁻¹ , each having a g value of 3.8±0.4. These lines are fitted using a perturbed Ising model to give a longitudinal interchain exchange strength of 51 cm⁻¹ and a relative longitudinal interchain exchange value of 0.06 for RbCoBr₃ at 1.7 K.
A possible antiresonance line is reported at 114.6 cm⁻¹ for RbCoBr₃ and preliminary work is reported in the search for magnons in other CsNiCl₃ type crystals
Towards practice-based studies of HRM: an actor-network and communities of practice informed approach
HRM may have become co-terminus with the new managerialism in the rhetorical orthodoxies of the HRM textbooks and other platforms for its professional claims. However, we have detailed case-study data showing that HR practices can be much more complicated, nuanced and indeed resistive toward management within organizational settings.
Our study is based on ethnographic research, informed by actor-network theory and community of practice theory conducted by one of the authors over an 18-month period. Using actor-network theory in a descriptive and critical way, we analyse practices of managerial resistance, enrolment and counter-enrolment through which an unofficial network of managers used a formal HRM practice to successfully counteract the official strategy of the firm, which was to close parts of a production site. As a consequence, this network of middle managers effectively changed top management strategy and did so through official HRM practices, coupled with other actor-network building processes, arguably for the ultimate benefit of the organization, though against the initial views of the top management.
The research reported here, may be characterized as a situated study of HRM-in-practice and we draw conclusions which problematize the concept of HRM in contemporary management literature
