The plantar soft tissue plays a critical role in absorbing shocks and attenuating excessive stresses during walking. Plantar soft tissue property and plantar pressure are critical information for footwear design and clinical assessment. The aim of this study was to investigate the relationship between plantar soft tissue hardness and plantar pressure during walking.

59 healthy volunteers (27 males and 32 females, aged 20 to 82) participated in this study. The plantar surface was divided into five regions lateral rearfoot, medial rearfoot, lateral midfoot, lateral forefoot, and medial forefoot, and the plantar tissue hardness was tested using Shore durometer in each region. Average dynamic pressures in each region were analyzed for the five regions corresponding to the hardness tests. The relationship between hardness and average dynamic pressure was analyzed in each region.

The average hardness of the plantar soft tissue in the above five regions is as follows lateral rearfoot (34.49 ± 6.77), medial rearfoot (34.47 ± 6.64), lateral midfoot (27.95 ± 6.13), lateral forefoot (29.72 ± 5.47), and medial forefoot (28.58 ± 4.41). Differences of hardness were observed between age groups, and hardness of plantar soft tissues in forefoot regions increased with age (

< 0.05). A negative relationship was found between plantar soft tissue hardness and pressure reduction at lateral rearfoot, medial rearfoot, and lateral midfoot (

< 0.05).

The hardness of plantar soft tissues changes with age in healthy individuals, and there is a trend of increasing hardness of the plantar soft tissue with age. The plantar soft tissue hardness increases with plantar pressure.

The hardness of plantar soft tissues changes with age in healthy individuals, and there is a trend of increasing hardness of the plantar soft tissue with age. The plantar soft tissue hardness increases with plantar pressure.Speculation has become a normalized occupational strategy and quotidian economic rationality that extends throughout society. selleck chemicals llc Although there are many contemporary articulations of speculation, this article focuses on contract labor as a domain of financialization. Seen through this lens, contract labor can be understood as a speculative investment strategy wherein individuals leverage whatever assets they have at their disposal-savings, time, bodily health-to capture economic advantages. In particular, we explore the speculative practices of healthy individuals who enroll in pharmaceutical drug trials as their primary or critical source of income. Mobilizing speculative logics to maximize the money they can earn from their clinical trial participation, these contract workers employ what we term a future-income-over-immediate-pay calculus. This speculative calculus valorizes fictional projections of significant long-term future income over present financial opportunities. For the economically precarious individuals in our study, we argue that rather than effectively increasing their income, speculation on contract work serves a compensatory function, providing an important-but ultimately inadequate-sense of control over market conditions that thrive upon workers’ economic insecurity.Our understanding of how stress affects primary school children’s attention and learning has developed rapidly. We know that children experience differing levels of stressors (factors that cause stress) in their environments, and that this can influence how they respond to new stressors when they occur in educational contexts. Here, we review evidence showing that stress can increase children’s attention and learning capacities in some circumstances but hinder them in others. We show how children differ in their attention and learning styles, dependent on stress levels for example, more highly stressed children may be more distracted by superficial features and may find it harder to engage in planning and voluntary control. We review intervention research on stress management techniques in children, concentrating on psychological techniques (such as mindfulness and stress reappraisal), physiological techniques (such as breathing exercises) and environmental factors (such as reducing noise). At the current time, raising teachers’ awareness of pupils’ differing stress responses will be an important step in accommodating the differing needs of children in their classrooms.Participants in longitudinal studies that followed children into adulthood now have children of their own, which has enabled researchers to establish multiple-generation cohorts. In this article, I illustrate the benefits of multiple-generation cohort studies for developmental researchers, including (a) the impact of child and adolescent characteristics (i.e., preconception factors) on parenthood can be studied from a developmental perspective and without having to rely on retrospective reports, (b) intergenerational continuity and transmission can be examined for psychological, behavioral, and social development, and by comparing parent and offspring generations for the same developmental period, and (c) the interplay of genetic and environmental influences on parenting and child development can be disentangled. Even though multiple-generation studies pose unique logistical and methodological challenges, such cohorts are indispensable for rigorous research into parenting and the origins of child development.Sub-Saharan Africa (SSA) is rapidly urbanizing, and ambient air pollution has emerged as a major environmental health concern in growing cities. Yet, effective air quality management is hindered by limited data. We deployed robust, low-cost and low-power devices in a large-scale measurement campaign and characterized within-city variations in fine particulate matter (PM2.5) and black carbon (BC) pollution in Accra, Ghana. Between April 2019 and June 2020, we measured weekly gravimetric (filter-based) and minute-by-minute PM2.5 concentrations at 146 unique locations, comprising of 10 fixed (∼1 year) and 136 rotating (7 day) sites covering a range of land-use and source influences. Filters were weighed for mass, and light absorbance (10-5m-1) of the filters was used as proxy for BC concentration. Year-long data at four fixed sites that were monitored in a previous study (2006-2007) were compared to assess changes in PM2.5 concentrations. The mean annual PM2.5 across the fixed sites ranged from 26 μg m-3 at a peri-urban site to 43 μg m-3 at a commercial, business, and industrial (CBI) site.
