Pentadic cartography: Mapping the universe of discourse

Expressions of time have increasingly infused the rhetorical experience of post-industrial war, especially since 9/11. This essay demonstrates how these “signs of time” operate as one of three tropes: deadline/countdown, infinite/infinitesimal war, and the ticking clock. The persistence of such signs of time in public discourse can be seen as an expression of what Paul Virilio has called the “chronopolis,” a political universe textured by real-time communication technologies. The chronopolitical will exhibits certain autocratic traits at odds with democratic ideals, primarily the refashioning of citizen identity into that of the “contemporary.” The analysis here charts the autocratic rhetoric of the chronopolis as a critical democratic project.     

Empirical Tests of a Brain-Based Model of Executive Function Development

Executive function (EF) plays a foundational role in development. A brain-based model of EF development is probed for the experiences that strengthen EF in the dimensional change card sort task in which children sort cards by one rule and then are asked to switch to another. Three-year-olds perseverate on the first rule, failing the task, whereas 4-year-olds pass. Three predictions of the model are tested to help 3-year-olds (N = 54) pass. Experiment 1 shows that experience with shapes and the label “shape” helps children. Experiment 2 shows that experience with colors—without a label—helps children. Experiment 3 shows that experience with colors induces dimensional attention. The implications of this work for early intervention are discussed.     

Using an Assistive Technology Toolkit to Promote Inclusion

Although the use of assistive technology for young children is increasing, the lack of awareness and the lack of training continue to act as major barriers to providers using assistive technology. This article describes an assistive technology toolkit designed for use with young children with disabilities that can be easily assembled and implemented by early childhood professionals. Specifically, we will describe assistive technology tools that support young children’s participation in their daily activities that involve movement and sensory needs, communication, and interaction with materials and offer strategies on how to implement these devices. An assembled toolkit that allows young children with disabilities immediate access to experiences that lead to acquisition of skills they need to learn and grow is discussed.     

Mobility in China, 2020: a tale of four phases

2020 was an unprecedented year, with rapid and drastic changes in human mobility due to the COVID-19 pandemic. To understand the variation in commuting patterns among the Chinese population across stable and unstable periods, we used nationwide mobility data from 318 million mobile phone users in China to examine the extreme fluctuations of population movements in 2020, ranging from the Lunar New Year travel season (chunyun), to the exceptional calm of COVID-19 lockdown, and then to the recovery period. We observed that cross-city movements, which increased substantially in chunyun and then dropped sharply during the lockdown, are primarily dependent on travel distance and the socio-economic development of cities. Following the Lunar New Year holiday, national mobility remained low until mid-February, and COVID-19 interventions delayed more than 72.89 million people returning to large cities. Mobility network analysis revealed clusters of highly connected cities, conforming to the social-economic division of urban agglomerations in China. While the mass migration back to large cities was delayed, smaller cities connected more densely to form new clusters. During the recovery period after travel restrictions were lifted, the netflows of over 55% city pairs reversed in direction compared to before the lockdown. These findings offer the most comprehensive picture of Chinese mobility at fine resolution across various scenarios in China and are of critical importance for decision making regarding future public-health-emergency response, transportation planning and regional economic development, among others.     

Discrimination‐Related Stress Effects on the Development of Internalizing Symptoms Among Latino Adolescents

This three‐wave longitudinal study of 173 Latino adolescents (M = 16.16 years, SD = 0.65) is designed to understand the role of discrimination‐related stress in mental health trajectories during middle to late adolescence with attention to differences due to immigration status. The results of the growth curve analysis showed that anxious‐depressed, withdrawn‐depressed, and somatic complaints significantly decreased over time. Furthermore, although discrimination‐related stress was found to be significantly related to the trajectories of three types of mental health symptoms, the results revealed that immigration status moderated these relations such that discrimination‐related stress was significantly related to these outcomes for Latino youth whose parents were born in the United States, while this relation was not significant for Latino children of immigrants.     

Transferring Leadership Skills: When Community College Presidents Become University Professors

University graduate-level programs are striving to address needs for community college leaders. One way they are doing this is by strengthening their graduate programs with relevant community college courses. Increasingly, however, community college presidents are being invited to join universities in professorial roles. These new graduate faculty leaders are bringing valuable transferable skills and experiences, but they are also experiencing transitional challenges. Studies have been conducted about other university executive administrators transitioning to university professor roles, but no studies have been conducted about community college presidents making this transition. This article represents an initial effort to explore a distinct class of leaders within academe—community college presidents-turned-professor. The findings of this exploratory study of 12 former community college presidents who transitioned to graduate university professors are reported along with stories, lessons learned, and advice for successfully crossing over from the community college sector to the university one.     

The relationship between teacher stress and burnout in Hong Kong: positive humour and gender as moderators

In this study, we report on the relationship between positive humour and burnout among 379 secondary school teachers in Hong Kong, and explore whether the relationship varies according to gender. The moderating effects of both affiliative and self-enhancing humour on each burnout component were then examined. High affiliative and self-enhancing humour were found to be associated with lower emotional exhaustion and depersonalisation but higher personal accomplishment. Further, the results indicated that low levels of affiliative and self-enhancing humour were related to more depersonalisation among females than among males. The results also partially supported the stress-moderating hypothesis, as affiliative humour was found to buffer the stress–depersonalisation relationship in this sample. These findings suggest that schools can design continuing education programmes based on the use of positive humour in helping teachers to cope with burnout.
