The relationship between perceived ageism and depressive symptoms in later life: Understanding the mediating effects of self-perception of aging and purpose in life,using structural equation modeling     

Hyejin Kim  Bruce A. Thyer  Jean C. Munn 《Educational gerontology》2019,45(2):105-119

The purpose of this study is to examine the relationship between perceived ageism and depression in later life and to clarify the mechanism underlying this relationship by examining the mediating effects of self-perception of aging and purpose in life. The Health and Retirement Study surveys were used for this secondary analysis of data. The sample included 3,991 older adults, and structural equation modeling (SEM) analyses using structural regression models were conducted. SEM analyses revealed that full mediation effects of self-perception of aging and purpose in life exist. Older adults who perceive ageism are likely to have negative self-perception of aging, and this negative view of their own aging is likely to decrease purpose in life and increase depressive symptoms. The results of this study imply that more efforts and resources are necessary to reduce ageism and its negative effect on depression among older adults. Additionally, the current study suggests the necessity of anti-ageism policies and social services. Increasing positive self-perception of aging, purpose in life, and resilience could be the key to a better quality of life for older adults.  相似文献

Robotic automation of droplet microfluidics     

Tuan M. Tran  Samuel C. Kim  Cyrus Modavi  Adam R. Abate 《Biomicrofluidics》2022,16(1)

Droplet microfluidics enables powerful analytic capabilities but often requires workflows involving macro- and microfluidic processing steps that are cumbersome to perform manually. Here, we demonstrate the automation of droplet microfluidics with commercial fluid-handling robotics. The workflows incorporate common microfluidic devices including droplet generators, mergers, and sorters and utilize the robot''s native capabilities for thermal control, incubation, and plate scanning. The ability to automate microfluidic devices using commercial fluid handling will speed up the integration of these methods into biological workflows.  相似文献   

Creative labor as moral and ethical subjects and its limitation: Creative City Yokohama,Japan     

Changwook Kim 《Inter-Asia Cultural Studies》2019,20(1):39-55

This study aims to reconsider and re-evaluate the rapid circulation of global creative city policy from the viewpoint of its creative workforce by focusing on the case of Yokohama, Japan. To shed light on this workforce’s everyday experiences and labor subjectivity, this investigation draws ideas from recent research trends of “creative labor” from the field of media and cultural studies, sociology of work, and political economy of communication. Based on in-depth interviews and participant observations, this research focuses on how the ethical and moral dimensions of labor subjectivity in creative work are prominently important in explaining Yokohama workers’ everyday living and working experiences as creative labor. Unexpectedly, this study found that these moral and ethical sentiments and actions, which take on the role of retaining their labor motivation, actually limit the development of political subjects who can resist given precarious working conditions and thereby hinder them from building a collective solidarity as “workers.” Thus this investigation concludes that the creative worker’s subjectivity retreats to solely a moral dimension rather than to a political one. Through this finding, this study explores whether the articulation of moral-political and social values in the course of cultural work can evolve from creative workers’ moral and ethical sensitivities and actions.  相似文献

The influence of water depth on kinematic and spatiotemporal gait parameters during aquatic treadmill walking     

Taeyou Jung  Yumi Kim  Hyosok Lim  Konstantinos Vrongistinos 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(3):297-307

The purpose of this study was to investigate kinematic and spatiotemporal variables of aquatic treadmill walking at three different water depths. A total of 15 healthy individuals completed three two-minute walking trials at three different water depths. The aquatic treadmill walking was conducted at waist-depth, chest-depth and neck-depth, while a customised 3-D underwater motion analysis system captured their walking. Each participant’s self-selected walking speed at the waist level was used as a reference speed, which was applied to the remaining two test conditions. A repeated measures ANOVA showed statistically significant differences among the three walking conditions in stride length, cadence, peak hip extension, hip range of motion (ROM), peak ankle plantar flexion and ankle ROM (All p values < 0.05). The participants walked with increased stride length and decreased cadence during neck level as compared to waist and chest level. They also showed increased ankle ROM and decreased hip ROM as the water depth rose from waist and chest to the neck level. However, our study found no significant difference between waist and chest level water in all variables. Hydrodynamics, such as buoyancy and drag force, in response to changes in water depths, can affect gait patterns during aquatic treadmill walking.  相似文献

Effects of the “Gangnam Style Syndrome” on the South Korean stock market     

Hyun Joung Jin  Jang-Chul Kim 《Journal of Cultural Economics》2018,42(1):139-161

This study attempts to answer two questions. First, can a single cultural event impact the stock prices of a wide range of companies and sectors? Second, was the positive stock market response in the information technology (IT) sector as well as performing arts sector significant? To answer these questions, we examine whether a hit pop single, “Gangnam Style” by Park Jae-Sang in 2012, affected related sectors of the Korean stock market and whether market reactions went beyond the stock price of the singer’s agency to affect those of other firms. We use an event study approach. The results show two notable empirical findings. First, although the findings indicating abnormal returns and cumulative abnormal returns appear mixed, the overall results imply that the unprecedented worldwide hit single by the South Korean singer positively affected the Recreation & Culture and Digital Content sectors. In other words, the market interpreted the event as good news, with shareholders expecting positive effects on the related sectors. Second, a positive stock market response was observed in the IT sector as well.  相似文献
