Convertibility of Cultural Capital: A Longitudinal Study of University Students From 2017 to 2024
The British Journal of Sociology, EarlyView.ABSTRACT A defining feature of cultural capital is its propensity for accumulation and the potential of its convertibility. However, there are a lack of studies that would explore how different forms of cultural capital could be employed as an advantage.

British Journal of Educational Psychology, EarlyView.Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

2D Piecewise Linear Scalar Fields with Invertible Integral Lines
Computer Graphics Forum, EarlyView.Abstract Integral lines of the gradient flow are standard features in continuously differentiable scalar fields that enjoy some useful properties: They cover the domain densely, do not split, merge, or intersect, and are therefore invertible. For widely used discretizations of scalar fields, the corresponding polygonal approximations of integral lines ...

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

International Statistical Review, EarlyView.Summary Understanding the spread of infectious diseases such as COVID‐19 is crucial for informed decision‐making and resource allocation. A critical component of disease behaviour is the velocity with which disease spreads, defined as the rate of change between time and space.

A generalization of Everett's result on the Collatz 3x + 1 problem
Advances in Applied Mathematics, 1987 For the problem of the title \textit{C. J. Everett} [Adv. Math. 25, 42-45 (1977; Zbl 0352.10001)] has proved that almost every natural number m, \(m>1\), has an iterate less than m. The author generalizes this result as follows: Let N be a natural number, x a real number and \(\pi_ k(x)=card\{m\leq x\); m a natural number and for some natural number n,

Journal of the American Geriatrics Society, EarlyView.ABSTRACT Background Risks related to long‐term opioid therapy for chronic pain are high and may increase over time with aging. Deprescribing may be a beneficial intervention for older adults prescribed chronic opioids. Methods Semi‐structured interviews with hypothetical clinical cases of older adults prescribed opioids for chronic pain: (1) low‐risk ...

Journal of Paediatrics and Child Health, EarlyView.ABSTRACT Background Bronchopulmonary dysplasia (BPD) is the most common complication of preterm birth and may lead to difficulties with oxygen control even at home. How oxygenation is managed outside the hospital and in high and low resourced settings is unclear. Aims To determine clinician perspectives for managing oxygenation after hospital discharge
