Diasporic youth culture of K-pop

This study examines how diasporic Korean youth engage with the recent global circulation of South Korean pop music (‘K-pop’). It explores how young diasporic Koreans negotiate K-pop as an ethnic and/or global cultural form in their transition to adulthood. Drawing on interviews with young people of Korean heritage in Canada, the study addresses how a diasporic sound, which connects the nostalgia for the ancestral homeland and the global mediascape, is appropriated for young people’s identity work. By examining diasporic Korean fans’ consumption of K-pop, this study suggests a perspective for understanding the recent K-pop phenomenon as a diasporic youth cultural practice.     

A longitudinal analysis of the relationships among daytime dysfunction,fatigue, and depression in college students

Objective: To examine the longitudinal trajectory of daytime dysfunction (DD) and its relationship with fatigue by depression status in university students.

Participants: 243 students completed online surveys from September- December 2016.

Methods: Surveys were conducted at three time points over a semester period: the beginning of the semester, the end of mid-term and the end of the semester.

Results: Results indicated that the DD significantly increased in all students over the semester. Students with depression showed a higher initial level of DD and faster rate of change compared to those without depression. A faster rate of change of DD predicted a higher level of end-semester fatigue.

Conclusions: Depression is related to a higher initial level of DD and its faster rate change which in turn, predicted end-semester fatigue, identifying one of the possible pathways through which depression impacts the functioning and health of affected students.     

Coordinated scheduling of production and delivery stages with stage-dependent inventory holding costs

This paper considers a problem of integrated decision-making for job scheduling and delivery batching wherein different inventory holding costs between production and delivery stages are allowed. In the problem, jobs are processed on a facility at a production stage and then delivered at the subsequent delivery stage by a capacitated vehicle. The objective is to find the coordinated schedule of production and delivery that minimizes the total cost of the associated WIP inventory, finished product inventory and delivery, where both the inventory costs are characterized in terms of the weighted flow-time and the delivery cost is proportional to the required number of delivery batches. It is proved that the problem is NP-hard in the strong sense. Thereupon, three heuristic algorithms are derived. Some restricted cases are also characterized as being solvable in polynomial time. Numerical experiments are conducted to evaluate the performance of the derived heuristic algorithms.     

What is child care? Lessons from time-use surveys of major English-speaking countries

This paper examines the definition and measurement of time devoted to child care in the diary-based surveys administered by the United States, Canada, Australia, and Great Britain. Detailed analysis of the relationship between measures of care activity and supervisory care in the American Time Use Survey (ATUS) illustrate the larger conceptual issues at stake.

Return on investment (ROI) of international public relations: A country-level analysis

The purpose of this study is to examine the relationship between economic outcome and international public relations investment by other countries in the U.S. Based on country-level data analysis, this study found that the number of international public relations contracts by other countries in the U.S. was positively related to (1) U.S. imports from those countries, (2) U.S. direct investment to those countries, and (3) the number of U.S. tourists visiting those countries, after controlling for economic size.     

Adjustment Strategy Use in Minority Family Businesses: Differences Across Gender

The objectives of this study were to explore the adjustment strategies employed by minority female owners of small family firms and to compare their use of adjustment strategies with those of their male counterparts. There were significant gender differences in the adoption of adjustment strategies among minority-owned family firms. The major findings of this study suggest that minority female business owners were more likely to reallocate family resources to help with business tasks and were more likely to intertwine both tasks than minority male business owners when demands were particularly great for the family or the firm. In addition, compared to male business owners, a relatively higher proportion of female business owners used volunteer help without pay during hectic times. Implications for business consultants and educators working with minority business owners are discussed.     

The racialised mobility of transnational working holidays

This study explores how transnational working holidaymakers imagine and negotiate their identity positions in ethno-racial structures of the host society. Drawing on qualitative interviews with 53 Korean working holidaymakers in Canada, the study addresses how the young people are racialised by being exposed to the ‘white gaze’ and re-ethnicised by engaging with the Korean diaspora. The study examines how the transnational mobility of working holidays both breaks from and continues the mobile subjects’ ethno-racial identity. The study’s findings contribute to the understanding of the racial dimensions of working holidaymaking, a largely overlooked topic in previous tourism studies.     

Understanding the role of schools in the Asian-white gap: a seasonal comparison approach

Asian Americans are the most highly educated racial group in the United States and are commonly heralded as the model minority for their high academic success. Nevertheless, previous research suggests that Asian Americans may face certain disadvantages in school settings. For example, Asian Americans’ academic advantage over non-Hispanic white students diminishes between kindergarten entry and the next several years of schooling. This study provides a closer examination of the educational progress of Asian American students compared to white students through a seasonal comparison approach. Using the Northwest Evaluation Association, we analyze reading and math scores for over 130,000 Asian American and white students in grades K-7 in approximately 675 public schools across the US. We find that Asian Americans have higher academic achievement than white students in general, but that these advantages are maintained primarily through faster rates of learning during the summer months. When school is in session, the Asian advantage either remains unchanged or shrinks, consistent with the view that some school processes undermine the educational progress of Asian American students relative to white students.     

Slow-explosive AR(1) processes converging to random walk

Abstract

This article investigates slow-explosive AR(1) processes, which converge to a random walk (RW) process with logarithm rates, to fill the gap between nearly non-stationary AR(1) and moderately deviated AR(1) processes, and derives the asymptotics of the least squares estimator using central limit theorems for (reduced) U-statistic. We successfully establish the smooth link between the nearly non-stationary AR(1) and the moderately deviated AR(1) processes. Some novel results are reported, which include the convergence of the least squares estimator to a biased fractional Brownian motion.
