Employee turnover is a major challenge facing the federal workforce, which has lost more employees to voluntary turnover than any other form of turnover. This study determined the associations between engagement, demographic factors, and voluntary turnover intention by analyzing 2015 Federal Employee Viewpoint Survey…

Population turnover, a key trait shaped by the organism’s life history strategy, plays an important role in eco-evolutionary dynamics by fixing the timescale for individual birth and death events as well as in determining the level of demographic stochasticity related to growth. Yet, the standard theory of population…

Background Relationships between dietitians and other healthcare providers can impact the degree to which patient care is collaborative; inefficient communication can lead to suboptimal care. It takes time for multidisciplinary team members to build collaborative, trusting relationships. For this reason, frequent…

Bundles of actin filaments with similar positions and orientations commonly occur in cytoskeletal networks. We use mathematical modelling and simulation to investigate how filament turnover and mechanics influence contractility and bundle formation in disordered actomyosin networks. Using a two-dimensional agent-based…

Turnover is one of the measures of the NH workforce stability. While the retention rate focuses on how long the existing workforce stays in the same NH, turnover measures how many workers leave the NH within a given period (). Turnover refers to the proportion of (existing and newly employed) staff who leave the NH in…

There were conflicting definitions and misrepresentations of turnover frequency (TOF), catalytic cycle frequency (CCF), and catalytic first-order rate constant (kcat) in the literature. Based on the Benfield and Lineweaver-Burk methods, data were generated. The results showed that the CCF for the forward (3.63 exp.…

Range migrations in response to climate change, invasive species and the emergence of novel ecosystems highlight the importance of temporal turnover in community composition as a fundamental part of global change in the Anthropocene. Temporal turnover is usually quantified using a variety of metrics initially developed…

Despite the relatively high turnover rates and increasing demand for homecare, little is known about the costs of turnover for homecare employers. To create effective policies to reduce turnover and associated costs, employers require an understanding of what factors contribute to the costs of turnover. Building upon…

A framework for catalysis based on categorical aperture selection rather than temporal acceleration is presented. Traditional catalysis theory describes catalysts as agents that accelerate reactions by lowering activation energies, implicitly treating time as the fundamental variable and reaction rate enhancement as…

Turnover of species composition through time is frequently observed in nature. Often explained by changes in abiotic conditions or regional species pools, compositional turnover is employed as an indicator of external stress in natural ecosystems. Theoretically, the possibility of turnover driven by intrinsic…

All cells maintain an axis of polarity that directs the orientation of growth. Cell polarity can be reorganized during development and in response to extrinsic cues to produce new cell types. Rho GTPases are central regulators of cell polarity and signal-dependent cell differentiation. We show here that one of the best…

One of the more disruptive reforms associated with the modern Internet is the emergence of online communities working together on knowledge artefacts such as Wikipedia and OpenStreetMap. Recently it has become clear that these initiatives are vulnerable because of problems with membership turnover. This study presents…

Culture’s substrate is the social network, linking social factors to cultural evolution in a variety of ways. Population size and structure have been well studied, yet little is known about variation in population turnover—the cyclic replacement of individuals in fission-fusion social systems. Using a generative…

An investment portfolio consists of n algorithmic trading strategies, which generate vectors of positions in trading assets. Sign opposite trades (buy/sell) cross each other as strategies are combined in a portfolio. Then portfolio turnover becomes a non linear function of strategies turnover. It rises a problem of…

Objective Turnover intention of employees in elderly caring social organizations has a significant impact on elderly care service delivery. This study investigated the associated factors of turnover intention among employees of elderly caring social organizations in Anhui Province, China. Methods A total of 605…

Acceleration of catalytic transformation of molecules via heterogeneous materials occurs through design of active binding sites to optimally balance the requirements of all steps in a catalytic cycle. In accordance with the Sabatier principle, the characteristics of a single binding site are balanced between at least…

Plant-pollinator interaction networks are dynamic in time and space. Interaction turnover consists of interaction rewiring (i.e., changes in interactions independent of species turnover) and species turnover (i.e., the gain or loss of species present in the network). To capture network dynamics, it is crucial to…

Catalytic reactions on surfaces with forced oscillations in physical or electronic properties undergo controlled acceleration consistent with the selected parameters of frequency, amplitude, and external stimulus waveform. In this work, the general reaction of reversible A-to-B chemistry is simulated by varying the…

Turns are key performance actions in soccer, but can also induce high mechanical loads resulting in tissue damage or injury. This study aimed to quantify the turn demands of an elite English Premier League soccer team. Turning data were obtained from 49 soccer matches (2022-23 season), from a single team that played 35…
