Opportunities for educational innovations in authentic project-based learning: understanding instructor perceived challenges to design for adoption

Educational technology research and development - Authentic project-based learning (APBL) is a highly effective way for instructors to help students learn disciplinary skills, modes of thinking,...     

Next Steps for Mind,Brain, and Education: Strengthening Early‐Career Development

An increasing number of scholars are being trained in the field of mind, brain, and education (MBE), yet discussions of trainees' needs and how to meet them are rare. We, the inaugural International Mind, Brain, and Education Society (IMBES) Trainee Board, identify three broad needs of MBE trainees: guidance and support, greater access to and connections among the MBE community, and professional development. We report a first step to address these needs: a daylong trainee conference, which included sessions to foster connections among trainees, provide mentorship from MBE leaders, and provide knowledge and skill building for careers. Attendees' survey results suggest the conference successfully supported trainees' development. As substantial trainee needs remain, we offer specific ways that principal investigators, institutions, funding agencies, future IMBES trainee boards, and the MBE community can further address trainees' needs to support early‐career development and strengthen the MBE field generally.     

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

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.

Robotic automation of droplet microfluidics

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.     

Pauahi Bishop Museum: A Hawaiian Museum—Challenging the Past to Face the Future

Bishop Museum has been the focus of attention in Hawaiì and the mainland for its changes in direction from a traditional natural history museum to an entrepreneurial science learning center. Attention has focused on how well the museum, in changing its direction, serves its communities, especially its the Native Hawaiian community, and whether it should be undertaking contract research projects and contract public programs in partnership with hotels and other commercial businesses. The author, involved in a key role in several projects representing this change in direction, discusses controversial projects associated with repatriation, contract archaeology, and exhibits. The projects are described within the context of the museum's history as a Hawaiian institution. The controversies are then examined in terms of how the museum managed them and in so doing, how it met its mission of education and service. As we enter the twenty-first century, our ability to work with the community, especially the Native Hawaiian community, and remain financially viable will determine how we fare.     

The need-threat analysis: A scoring system for the children's apperception test

The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented.     

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

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.     

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

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.
