We present the Sydney Radio Star Catalogue, a new catalogue of stars detected at megahertz to gigahertz radio frequencies. It consists of 839 unique stars with 3 405 radio detections, more than doubling the previously known number of radio stars. We have included stars from large area searches for radio stars found using circular polarisation searches, cross-matching, variability searches, and proper motion searches as well as presenting hundreds of newly detected stars from our search of Australian SKA Pathfinder observations. The focus of this first version of the catalogue is on objects detected in surveys using SKA precursor and pathfinder instruments; however, we will expand this scope in future versions. The 839 objects in the Sydney Radio Star Catalogue are distributed across the whole sky and range from ultracool dwarfs to Wolf-Rayet stars. We demonstrate that the radio luminosities of cool dwarfs are lower than the radio luminosities of more evolved sub-giant and giant stars. We use X-ray detections of 530 radio stars by the eROSITA soft X-ray instrument onboard the Spectrum Roentgen Gamma spacecraft to show that almost all of the radio stars in the catalogue are over-luminous in the radio, indicating that the majority of stars at these radio frequencies are coherent radio emitters. The Sydney Radio Star Catalogue can be found in Vizier or at https://radiostars.org.

Clinical outcomes of repetitive transcranial magnetic stimulation (rTMS) for treatment of treatment-resistant depression (TRD) vary widely and there is no mood rating scale that is standard for assessing rTMS outcome. It remains unclear whether TMS is as efficacious in older adults with late-life depression (LLD) compared to younger adults with major depressive disorder (MDD). This study examined the effect of age on outcomes of rTMS treatment of adults with TRD. Self-report and observer mood ratings were measured weekly in 687 subjects ages 16–100 years undergoing rTMS treatment using the Inventory of Depressive Symptomatology 30-item Self-Report (IDS-SR), Patient Health Questionnaire 9-item (PHQ), Profile of Mood States 30-item, and Hamilton Depression Rating Scale 17-item (HDRS). All rating scales detected significant improvement with treatment; response and remission rates varied by scale but not by age (response/remission ≥ 60: 38%–57%/25%–33%; <60: 32%–49%/18%–25%). Proportional hazards models showed early improvement predicted later improvement across ages, though early improvements in PHQ and HDRS were more predictive of remission in those < 60 years (relative to those ≥ 60) and greater baseline IDS burden was more predictive of non-remission in those ≥ 60 years (relative to those < 60). These results indicate there is no significant effect of age on treatment outcomes in rTMS for TRD, though rating instruments may differ in assessment of symptom burden between younger and older adults during treatment.

German journalist Jürgen Hinzpeter won the 2003 Song Kun-ho Press Award for his reporting of the 1980 Kwangju Uprising. He was also the subject of documentaries and the 2017 hit movie A Taxi Driver, which credit him as the first journalist to expose the Kwangju Uprising to the world. In fact, Hinzpeter was one of many journalists who revealed what had happened at Kwangju. Since the production of the 2003 documentary Hinzpeter – the Blue-Eyed Witness to May 1980, interest in the many other foreign journalists who covered Kwangju has been elided, raising the question of why only Hinzpeter's contribution is remembered and celebrated. Using ideas about historical memory developed by Paul Cohen, I argue that a narrative about Hinzpeter's actions in Kwangju has emerged, which has little to do with who first broke the news of the Kwangju Uprising. The story of Hinzpeter's relationship with the South Korean democratization movement as well as the film he shot of the moment Kwangju citizens seized power and established an alternative government to military rule – have become important weapons for the activist generation in an ongoing struggle over the memorialization of the Kwangju Uprising.

Many scholars have stressed that regional dynamics led to the outbreak of the Musin Rebellion, the largest rebellion in eighteenth-century Korea. Scholars have examined the economic and political situation leading up to the violence and concluded that political marginalization caused Kyŏngsang Province elites (from the Southerner faction) to launch the rebellion. This paper analyses evidence from official sources about rebel motivations, rebel geographical associations and the court view of the causes. Although post-rebellion government statements acknowledge tensions between the court and many Kyŏngsang Province elites, rebel testimony showed no evidence of any anger about discrimination against elites from a single region. There is also inconsistent evidence of regional concerns in the membership of the rebel organization, which was drawn from three southern provinces and mainly concentrated around the capital. My findings challenge the conclusions of regionalist scholars and place the Musin Rebellion in a trajectory of late Chosŏn rebellion that was attempting to redress factional political discrimination and was not caused by regional concerns.

The 1728 Musin Rebellion was a failed attempt by factional members to overthrow militarily King Yŏngjo's government. Between 1736 and 1837, six stelae, dedicated to loyal subjects who resisted the rebels, were erected in three different provinces. These stelae contain historical descriptions of the rebellion, its suppression, and the political aftermath. Previous research centred on one stele, represented as evidence of worsening discrimination against Kyŏngsang province elites. This article considers the six stelae in relation to the wider political context of 1728–1837 and analyses consistencies in the text, political connections, location, and the target audience. The stelae reveal complex political struggles in post-rebellion Chosŏn, including a struggle for court recognition by loyalists in areas of rebel strength. Most significantly, the stelae reveal a struggle amongst the victors of the rebellion. The authors attempted to set the record straight over the loyalty of their officials – especially those who had been involved in some form of controversy during the Musin Rebellion – thereby proving their loyalty to Yŏngjo and their right to administer government. To show they were trustworthy court officials, moderate Disciple's faction supporters were also distancing themselves from Disciple's faction extremists that had led the Musin Rebellion.

The impact of dietary n-3 PUFA on behavioural outcomes has been widely researched; however, very little attention has been given to their impact on brain functioning in physiological terms. A total of twenty-two healthy adults took part in this double-blind, placebo-controlled study, wherein the cerebral haemodynamic effects of 12 weeks of daily dietary supplementation with either 1 g DHA-rich or 1 g EPA-rich fish oil (FO) or placebo (1 g olive oil) were assessed. Relative changes in the concentration of oxygenated Hb (oxy-Hb) and deoxygenated Hb were assessed in the prefrontal cortex using near IR spectroscopy (NIRS) during the performance of four computerised cognitive tasks. Supplementation with DHA-rich FO, in comparison with placebo, resulted in a significant increase in the concentrations of oxy-Hb and total levels of Hb, indicative of increased cerebral blood flow (CBF), during the cognitive tasks. In comparison, no effect on CBF was observed following supplementation with EPA-rich FO, where concentration changes in the chromophores followed the same pattern as placebo. These encouraging pilot data warrant further application of NIRS in this area.

The n-3 PUFA are a unique class of fatty acids that cannot be manufactured by the body, and must be acquired via dietary sources. In the UK, as well as in other Western nations, these ‘essential’ fatty acids are consumed in quantities that fall below government guidelines. The present study explored the effects of 12 weeks' dietary supplementation with 1 g/d of two types of fish oil (FO; DHA-rich and EPA-rich) in 159 healthy young adults aged 18–35 years. An assessment of performance on a battery of computerised cognitive tasks and mood measures took place before and following the 12-week treatment regimen. Venous blood samples were also supplied by participants at both time points which were later analysed for serum fatty acid concentrations. Despite good adherence to the study protocol – as reflected in increased concentrations of n-3 serum fatty acids – compared with placebo, the observed effects of both active treatments were minimal. The only finding of note revealed that supplementation with EPA-rich FO may reduce subjective mental fatigue at times of high cognitive demand, although further investigation is required. These findings, taken together with other recent reports of null effects, suggest that dietary supplementation with n-3 PUFA in healthy, normally developing and impairment-free populations is unlikely to result in cognitive enhancement.
