Instrumental tuition is by many seen as the cornerstone of higher music education (HME) performance programmes. An increasing body of research looks into its strengths and weaknesses and calls for development in a number of ways. This study contributes to this debate by exploring the ways in which international instrumental tuition practices are different, however limited to Western classical music practices. The article reports on a qualitative interview study of 12 students with experiences from 11 countries across America, Europe and Asia. Analysis of the interview data suggests that instrumental tuition practices are different when it comes to teacher positions, lesson formats and social organisation, responsibility and student voice and subject matter foci. These differences seem to correspond to social, musical and pedagogical structures and assumptions, and they could, as a result, be seen as differences on an international, institutional and individual level. The study suggests further that instrumental tuition practices could be seen as various manifestations of and negotiations between two broad archetypes in education: a teacher-centred archetype and a student-centred archetype. Increased knowledge about the variety of instrumental tuition practices is potentially a crucial matter in the field of HME, not the least due to power issues, and the study provides an analytical framework to analyse international, institutional and individual practices.

Affective ties encompass a broad family of emotional phenomena, including love, affection, attachment, and devotion. Affective ties may appear deeply personal, and they most certainly are. But they are also important resources for the exercise of political power in international politics – not only as vulnerabilities that can be exploited for coercion but also, and more significantly, as means to mobilise action and sacrifice. Viewed from the vantage point of political agents, affective ties are thus power resources whose distribution in the international system shapes their strategies and choices. Viewed from the perspective of the system, the international realm is not only characterised by struggles over material capabilities or ideas but also competition over affective ties. Correspondingly, nationalism is not simply an identity. It is a collection of techniques and practices for generating and capturing affective ties that has emerged as a highly effective contender in this contest, with crucial implications for how the international system is organised. That being said, other forms of eliciting affective ties also persist.

Mounting geoeconomic competition between the United States (US) and China alongside the global shocks due to the COVID-19 pandemic and the Russia–Ukraine war have drawn significant attention to the instability and vulnerability issues in the global supply chain (GSC), which is critical for international trade, production, and economic security. Can the US, South Korea, and Japan successfully coordinate their efforts to establish a secure and resilient GSC in key industries? Can these efforts promote economic security? By defining the efforts to reshape the GSC as part of the US–China power competition, this study evaluates the impact of its restructuring around the US on various aspects of the economic and national security of South Korea and Japan. Overall, the findings highlight that restructuring the GSC poses complex challenges for South Korea and its foreign policy in the contemporary globalization era.

The nonparametric Wilcoxon-Mann-Whitney test is commonly used by experimental economists for detecting differences in central tendency between two samples. This test is only theoretically appropriate under certain assumptions concerning the population distributions from which the samples are drawn, and is often used in cases where it is unclear whether these assumptions hold, and even when they clearly do not hold. Fligner and Pollicello's (1981, Journal of the American Statistical Association. 76, 162-168) robustrank-ordertestis a modification of the Wilcoxon-Mann-Whitney test, designed to be appropriate in more situations than Wilcoxon-Mann-Whitney. This paper uses simulations to compare the performance of the two tests under a variety of distributional assumptions. The results are mixed. The robust rank-order test tends to yield too many false positive results for mediumsized samples, but this liberalness is relatively invariant across distributional assumptions, and seems to be due to a deficiency of the normal approximation to its test statistic's distribution, rather than the test itself. The performance of the Wilcoxon-Mann-Whitney test varies hugely, depending on the distributional assumptions; in some cases, it is conservative, in others, extremely liberal. The tests have roughly similar power. Overall, the robust rank-order test performs better than Wilcoxon-Mann-Whitney, though when critical values for the robust rank-order test are not available, so that the normal approximation must be used, their relative performance depends on the underlying distributions, the sample sizes, and the level of significance used.

On December 14, 1959, amidst much fanfare and tears, the first repatriation boat (provided by the Soviet Union) carried thousands of Koreans from Niigata, Japan, to Cheongjin, North Korea. Hailed as a humanitarian project under the intermediation of the International Committee of the Red Cross, the repatriation of Koreans from Japan to North Korea continued until 1984, resulting in a total of more than 93,000 repatriates who relocated from Japan to North Korea amidst the Cold War division of the world with the majority never to return to Japan again. This article addresses multiple aspects of this project, looking into the media portrayal of North Korea at the time of the opening of the repatriation and the more recent academic discussion following the de-classification of the International Committee of the Red Cross papers. Based on these, the article frames the repatriation in a new light with the suggestion of possibly thinking about it as a form of human trafficking without reducing it into a one-dimensional political event or conspiracy by one government or another. Instead, the article emphasizes that the structure of power that sustained the repatriation was complex and so were the lives that repatriates experienced.

Who deserves credit for epistemic successes, and who is to blame for epistemic failures? Extreme views, which would place responsibility either solely on the individual or solely on the individual’s surrounding environment, are not plausible. Recently, progress has been made toward articulating virtue epistemology as a suitable middle ground. A socio-environmentally oriented virtue epistemology can recognize that an individual’s traits play an important role in shaping what that individual believes, while also recognizing that some of the most efficacious individual traits have to do with how individuals structure their epistemic environments and how they respond to information received within these environments. I contribute to the development of such an epistemology by introducing and elucidating the virtue of epistemic exactingness, which is characterized by a motivation to regulate the epistemically significant conduct of others.

Social power establishes and legitimizes actions for individuals within a society who accept the structures that create that power. Differences in power can develop without strict hierarchies, however. Here, we explore the power differences among groups living in the Mimbres Mogollon region of southwestern New Mexico using bioarchaeological data and a case study from the Harris site, a Late Pithouse period village occupied circa AD 550–1000. Aspects of mortuary practices and supporting archaeological data offer nuanced interpretations of individuals with situational power linked to social practices that both solidified and maintained power by particular households. The power differences documented here are not based on coercion; instead, they are tied to cooperation and engagement with the community. For small-scale communities such as Harris, situational power is interpreted for individuals with access to prime agricultural land and/or ritual, or by association with certain land-holding lineages. This system is consistent with a heterarchical structure that embraced flexibility in the use of power.

Statistical power is an important detail to consider in the design phase of any experiment. This paper serves as a reference for experimental economists on power calculations. We synthesize many of the questions and issues frequently brought up regarding power calculations and the literature that surrounds that. We provide practical coded examples and tools available for calculating power, and suggest when and how to report power calculations in published studies.
