Work-related factors predict changes in physical activity among nurses participating in a web-based worksite intervention: A randomized controlled trial

Background Despite the numerous benefits associated with physical activity (PA), most nurses are not active enough and few interventions have been developed to promote PA among nurses. A secondary analysis of raw data from a single-centre, three-arm parallel-group randomized controlled trial was conducted to assess whether work-related characteristics and general mood states predict changes in total weekly moderate-to-vigorous intensity PA (MVPA) and average daily step-count among nurses participating in a 6-week web-based worksite intervention. Methods Seventy nurses (meanage: 46.1 ± 11.2 years) were randomized to an individual-, friend-, or team-based PA challenge. Participants completed questionnaires pre- and post-intervention assessing work-related characteristics (i.e., shift schedule and length, number of hours worked per week, work role) and general mood states (i.e., tension, depression, anger, confusion, fatigue, vigour). Participants received a PA monitor to wear before and during the 6-week PA challenge, which was used to assess total weekly MVPA minutes and average daily step-count. Data were analyzed descriptively and using multilevel modeling for repeated measures. Results Change in total weekly MVPA minutes, but not change in average daily step-count, was predicted by shift schedule (rotating vs. fixed) by time (estimate = − 17.43, SE = 6.18, p = .006), and work role (clinical-only vs. other) by time (estimate = 18.98, SE = 6.51, p = .005). General mood states did not predict change in MVPA or change in average daily step-count. Conclusions Given that nurses who work rotating shifts and perform clinical work showed smaller improvements in MVPA, it may be necessary to consider work-related factors/barriers (e.g., time constraints, fatigue) and collaborate with nurses when designing and implementing MVPA interventions in the workplace.

A Biophysical Counting Mechanism for Keeping Time

The ability to estimate and produce appropriately timed responses is central to many behaviors including speaking, dancing, and playing a musical instrument. A classical framework for estimating or producing a time interval is the pacemaker-accumulator model in which pulses of a pacemaker are counted and compared to a stored representation. However, the neural mechanisms for how these pulses are counted remains an open question. The presence of noise and stochasticity further complicate the picture. We present a biophysical model of how to keep count of a pacemaker in the presence of various forms of stochasticity using a system of bistable Wilson-Cowan units asymmetrically connected in a one-dimensional array; all units receive the same input pulses from a central clock but only one unit is active at any point in time. With each pulse from the clock, the position of the activated unit changes thereby encoding the total number of pulses emitted by the clock. This neural architecture maps the counting problem into the spatial domain, which in turn translates count to a time estimate. We further extend the model to a hierarchical structure to be able to robustly achieve higher counts.

How Do I Count Thee? Various Angles for Examining the Doubling Times of the Amish

The focus of this article is the measurement of how rapidly various parts of Amish society grow, including the number of settlements, households, church districts, and ordained men. "Amish society" means those Plain Anabaptist communities that both identify themselves as Amish and forbid car ownership. Doubling time was selected as the statistic to examine this growth. It is a measure of how quickly a population doubles; that is, its exponential growth. Most of the doubling times calculated for this article were within a few years of the doubling time estimate of 20 years for the Amish population in general, based on statistics from the Young Center for Anabaptist and Pietist Studies. The article concludes with a discussion of what these measures of growth mean for the future of Amish society and extrapolations, based on current doubling times, by decade from 2020 to 2050. Recommended is a greater focus among Plain Anabaptist scholars on the population dynamics of the Amish, arguing that demographic dimensions underlie possible changes in the social, cultural, religious, and economic features of the Amish through the remainder of the twenty-first century.

Sarcomatous tumor of the right ovary, removed by laparotomy in the gynecological department at the Mogilev obstetric institution

Unfortunately, we do not yet have accurate statistics of malignant neoplasms of the ovaries. Virkhov, for example, of the opinion that they are quite rare. In Schroeder's 600 cases of neoplasms of the ovaries, there are only 10 cases of malignant, consequently somewhat more than 1%. Wert in relation to ovarian cysts determines the frequency of dense neoplasms in 5%. Spencer Wells initially rose 1.72%, followed by even less 1.2%. Leopold), from a more distant time, there are only 8 cases of malignant neoplasms of the ovaries: 4 cases of Spencer Wlls, of which two were fatal, two cases of Spiegelberg, both were fatal, one case of Buren and one recovered a rural doctor whose patient died of a collapse shortly after the operation. Even if we assume that cases of malignant neoplasms of the ovaries are quite rare, then all the same, judging by the latest reports, it cannot be argued that this rarity would be in such a scale as the authors just cited for a longer time estimate it.

Global quieting of high-frequency seismic noise due to COVID-19 pandemic lockdown measures

Human activity causes vibrations that propagate into the ground as high-frequency seismic waves. Measures to mitigate the coronavirus disease 2019 (COVID-19) pandemic caused widespread changes in human activity, leading to a months-long reduction in seismic noise of up to 50%. The 2020 seismic noise quiet period is the longest and most prominent global anthropogenic seismic noise reduction on record. Although the reduction is strongest at surface seismometers in populated areas, this seismic quiescence extends for many kilometers radially and hundreds of meters in depth. This quiet period provides an opportunity to detect subtle signals from subsurface seismic sources that would have been concealed in noisier times and to benchmark sources of anthropogenic noise. A strong correlation between seismic noise and independent measurements of human mobility suggests that seismology provides an absolute, real-time estimate of human activities.

Wellbeing and cognition are coupled during development: A preregistered longitudinal study of 1137 children and adolescents

Wellbeing and cognition are linked in adulthood, but how the two domains interact during development is currently unclear. Using a complex systems approach, we preregistered and modelled the relationship between wellbeing and cognition in a prospective cohort of 1137 children, aged 6 - 7 up to 15 years. We found bidirectional interactions between wellbeing and cognition that unfold dynamically over time. Higher externalizing symptoms in childhood predicted fewer gains in planning over time (estimate = - 0.24, p = .019), whereas higher childhood vocabulary predicted smaller increases in loneliness over time (estimate = -0.62, p = < .001). These interactions were characterized by modifiable risk and resilience factors: Relationships to parents, friendship quality, socioeconomic status and puberty onset were all linked to both cognitive and wellbeing outcomes. As such, cognitive and wellbeing are inextricably intertwined in during development and can be modified by social and biological factors.

A New Perspective on the Relationships between Individual Factors and Time Estimates

Despite its abundant literature, the timing research field does not offer any comparison of prospective and retrospective time estimates emerging from a within-subjects design. Likewise, the relationships between these estimates and individual factors, within such a design, have never been investigated. The present study addresses these issues. Ninety-two participants retrospectively and prospectively estimated the duration of an Internet surfing task and completed several questionnaires (e.g., personality). Results showed that (a) prospective time estimates were longer than retrospective ones for only 58% of the participants and (b) the relationships between individual factors and time estimates differed as a function of the fact that a participant had or not a longer prospective time estimate. The discussion explains the methodological, theoretical and practical impacts emerging from this new method for studying the relationships between individual factors and time estimates in daily life-like situations.

Aplikasi Mobile untuk Sistem Antrian Praktek Dokter Dilengkapi dengan Analisis Perhitungan Estimasi Waktu Menggunakan Markov Chain dan Algoritma PageRank

Along with the increasingly rapid development of technology, especially in the field of computers, ways to overcome the problem of patient queues have been developed. One of them is the use of a mobile application to get a time estimate until a patient gets a turn to consult with a doctor. Many industries still use manual methods to overcome this queue problem. Based on this fact, this final project with title "Mobile Applications for Doctor Examination Queue System Equipped with Analysis of Time Estimation Calculation Using the Markov Chain and PageRank Algorithm" has aims to get time estimates for the patients so that time can be more efficient.
