eHealth in Geriatric Rehabilitation: An International Survey of the Experiences and Needs of Healthcare Professionals

While eHealth can help improve outcomes for older patients receiving geriatric rehabilitation, the implementation and integration of eHealth is often complex and time-consuming. To use eHealth effectively in geriatric rehabilitation, it is essential to understand the experiences and needs of healthcare professionals. In this international multicentre cross-sectional study, we used a web-based survey to explore the use, benefits, feasibility and usability of eHealth in geriatric rehabilitation settings, together with the needs of working healthcare professionals. Descriptive statistics were used to summarize quantitative findings. The survey was completed by 513 healthcare professionals from 16 countries. Over half had experience with eHealth, although very few (52 of 263 = 20%) integrated eHealth into daily practice. Important barriers to the use or implementation of eHealth included insufficient resources, lack of an organization-wide implementation strategy and lack of knowledge. Professionals felt that eHealth is more complex for patients than for themselves, and also expressed a need for reliable information concerning available eHealth interventions and their applications. While eHealth has clear benefits, important barriers hinder successful implementation and integration into healthcare. Tailored implementation strategies and reliable information on effective eHealth applications are needed to overcome these barriers.
Pore Pressure Drop During Dynamic Rupture and Conditions for Dilatancy Hardening

Pore pressure drop brought about by fault dilatancy during accelerating slip may suppress nucleation of earthquakes. Yet, direct measurements of pore pressure during dynamic slip are challenging to produce. We present results of a physics‐based model simulating onset of slip in saturated granular layers coupled to a constant fluid pressure reservoir. Grain rearrangements required for slip to commence induce incipient rapid dilatation during which the maximum pore pressure drop is generated. We find that up to a critical slip rate the pore pressure drop is consistent with a prediction derived for an incompressible fluid flow. In this “drained” regime, excess pore pressure is efficiently relaxed and has little effect on slip stability. Above the critical slip rate, marking the onset of undrained conditions, the pore pressure drop decays slowly, inhibits dilatation rate, and significantly increases strength of the layer, stabilizing the rupture growth. The magnitude of the pore pressure drop increases monotonically with the drainage number given as the ratio of the dilatation rate to a characteristic fluid infiltration rate. The pore pressure drop in the undrained regime also depends on a second non‐dimensional parameter, βσn′ $\beta {\sigma }_{\mathrm{n}}^{\prime }$ , where β is storage capacity, and σn′ ${\sigma }_{\mathrm{n}}^{\prime }$ is the effective normal stress. Low values of this parameter enhance localization of strain near the drained boundaries of the layer, promoting fluid flow into the layer. Our results can be used to better constrain drainage conditions associated with changes in slip rate, the magnitude of the generated pore pressure and the corresponding fault strengthening.
Nucleation of filaments of the TGBA phase in free-standing films

ABSTRACT A model of filament nucleation in the twist grain boundary A (TGBA) phase in free-standing smectic films is proposed. It is based on a concept of finite blocks of parallel smectic layers forming a helical structure in the interior of a film. In our model, the blocks resemble twin-like domains in smectic-A liquid crystal. The blocks are mediated to surrounding smectic layers in film either continuously (coherent twin boundary) or discontinuously via dislocation loops wrapping up blocks. Edge components of dislocation loops form incoherent twin boundary. Screw components forming twist grain boundary connect neighbour blocks among themselves. Nucleation of TGBA filament in a film is treated using a simplified model based on isotropic smectic-A elastic theory. Discussion showed that filaments can be nucleated just below the transition temperature from the isotropic to the TGBA phase under slow temperature decrease. The nucleation of dislocation loops is possible due to low compression modulus of material which can be expected just below the transition temperature. Graphical Abstract
Partial Clonality Expands the Opportunity for Spatial Adaptation

Reproductive mode may strongly impact adaptation in spatially varying populations linked by dispersal, especially when sexual and clonal offspring differ in dispersal. We determined how spatial structure affects adaptation in populations with mixed clonal and sexual reproduction. In a source-sink quantitative genetic deterministic model (with stabilizing selection around different optima), greater clonal reproduction or parent-offspring association (a measure of the part of the parent’s phenotype other than the additive genetic component inherited by clonal offspring) increased the selective difference (difference between phenotypic optima) allowing sink populations to adapt. Given dispersal differences between clonally and sexually produced juveniles, adaptation increased with an increasing fraction of clonal dispersers. When considering migrational meltdown, partially clonal reproduction reduced cases where dispersal caused habitat loss. Stochastic individual-based simulations support these results, although the effect of differential dispersal was reversed, with decreased clonal dispersal allowing greater adaptation. These results parallel earlier findings that for an instantaneous shift in phenotypic optimum, increasing clonality allowed population persistence for a greater shift; here, selective change is spatial rather than temporal. These results may help explain the success of many partially clonal organisms in invading new habitats, complementing traditional explanations based on avoiding Allee effects.
Impacts of Spontaneous Waterfall Development on Bedrock River Longitudinal Profile Morphology

River profiles are shaped by climatic and tectonic history, lithology, and internal feedbacks between flow hydraulics, sediment transport and erosion. In steep channels, waterfalls may self‐form without changes in external forcing (i.e., autogenic formation) and erode at rates faster or slower than an equivalent channel without waterfalls. We use a 1‐D numerical model to investigate how self‐formed waterfalls alter the morphology of bedrock river longitudinal profiles. We modify the standard stream power model to include a slope threshold above which waterfalls spontaneously form and a rate constant allowing waterfalls to erode faster or slower than other fluvial processes. Using this model, we explore how waterfall formation alters both steady state and transient longitudinal profile forms. Our model predicts that fast waterfalls create km‐scale reaches in a dynamic equilibrium with channel slope held approximately constant at the threshold slope for waterfall formation, while slow waterfalls can create local channel slope maxima at the location of slow waterfall development. Furthermore, slow waterfall profiles integrate past base level histories, leading to multiple possible profile forms, even at steady‐state. Consistency between our model predictions and field observations of waterfall‐rich rivers in the Kings and Kaweah drainages in the southern Sierra Nevada, California, supports the hypothesis that waterfall formation can modulate river profiles in nature. Our findings may help identify how bedrock channels are influenced by waterfall erosion and aid in distinguishing between signatures of external and internal perturbations, thereby strengthening our ability to interpret past climate and tectonic changes from river longitudinal profiles.
Indonesia's Open Government: A Bibliometric Analysis

This study aims to analyse trends and models of open government in Indonesia. This study uses a qualitative approach with bibliometric analysis methods and a systematic literature review. The data in this study were obtained from the Google Scholar database using the Publish or Perish application and processed using the Vosviewer application. The results of this study indicate that Indonesian open government studies are quite attractive to researchers. Although fluctuating, in the last decade there have been 52 publications on Indonesian open government studies, and 267 of them have been cited. From these figures, an h-index score of 10 and a g-index score of 15 are obtained. There are 83 keywords divided into 15 clusters, with the number of keywords in each cluster varying. Of these keywords, there are 412 links, 440 total link strength, and 132 occurrences. In 2020–2022, the Government of Indonesia established 18 policy models to support the achievement of open government. Since 2011 until now, the government of Indonesia has consistently supported the implementation of open government by establishing 152 policy models.
The assessment of fatigue-related changes in stride mechanics, variability and long-range correlations in recreational and elite distance runners using foot-mounted inertial sensors

This thesis was designed to assess stride mechanics, variability and long-range correlations during running, as well as their relationship with fatigue and skill level. For this purpose, three separate experiments were conducted. As a first step, it was established whether a simple hardware setup consisting of a wireless foot-mounted inertial measurement unit (IMU) was capable of accurately measuring individual stride length vectors during distance running. The results showed that the sensor-based method displayed excellent levels of agreement with a 3D motion capture system as the criterion. Subsequently, the same setup was used to track a set of gait variables in a group of elite and recreational runners during an exhaustive overground run. It was established that long-range correlations (LRCs) decreased over the run, while no significant changes were observed in the coefficients of variation (CV). Group differences were found in mean stride length, contact time and peak impact acceleration, stride time CV as well as peak impact acceleration FSI. A final study assessed the impact of a fatiguing drop jump protocol on joint stiffness, stride mechanics and measures of variability. As before, a group of elite and recreational distance runners were recruited for this experiment. It was found that joint stiffness was significantly reduced after the fatiguing jumps. Additionally, mean stride time, as well as LRCs in the stride time and stride length series were reduced in response to the jumps. Group differences existed in knee joint stiffness and mean stride length. Notable interaction effects indicated that elite and recreational runners reacted differently to the fatiguing jumps with respect to mean ankle joint stiffness and stride length. Together, this thesis demonstrates that long-range correlations serve as a potential marker of neuromuscular fatigue during prolonged running. It also confirms that IMUs are capable of tracking a variety of gait parameters across a range of different distance running speeds.
Relationships between self-downing beliefs and math performance in Greek adolescent students: A predictive study based on Rational-Emotive Behavior Education (REBE) as theoretical perspective

There is ample evidence from both educational practice and research that math performance is often associated with increased levels of test anxiety, stress and discomfort and that students’ cognitions account for this performance. Rational-Emotive Behavior Education (REBE), derived from Ellis’s Rational-EmotiveBehavior Theory (REBT), supports that it is mainly students’ cognitions in the form of core (ir) rational beliefs that determine their performance and overallschool achievement. However, given the binary nature of the REBT model, it is less empirically known what is the type of relationship (linear or non-linear)between cognitions, such as core (ir) rational beliefs, and specific aspects of school performance such as mathematics. Hence, this study investigates the type of relationships between students’ self-downing beliefs (a type of students’ core irrational beliefs according to REBT) and academic math performance in students of secondary education. Greek adolescent students (Ν=116) from all grades of middle school and high school completed a self-downing subscale taken from the Child and Adolescent Scale of Irrationality; students’ scores from mathematical tests were collected directly from school records. A weak, though significant linear correlation was found between self-downing beliefs and academic math performance (r=-.21; p<.05), indicating 4.4% of common variance. Polynomial regression analysis revealed, however, that students’ self-downing beliefs significantly predicted academic math performance by means of a curvilinear relationship (R2=.10): the quadratic and cubic trend gave rise to 10% of the variance explained in math performance. Overall, these results are in line with the binary model of REBE according to which not only students’ lower self-downing beliefs, but also higher self-acceptance beliefs, may have a substantial impact on their math performance. The importance of the non-linear relationship found is discussed on the crucial importance of REBE as a form of social-emotional learning method that promotes better math performance through modification of problematic self-referent cognitions.
Comparison between Aqua-acupuncture and Trazodone on Mitigation of Fear, Anxiety and Stress in Healthy Dogs during Routine Veterinary Examination

Fear, anxiety and stress (FAS) are significant factors in human-animal interactions in veterinary hospital settings. The objective of this study was to determine the effect of aqua-acupuncture (Aqua-AP) compared with trazodone on the mitigation of FAS indicators in healthy, stressed dogs during routine veterinary examination and procedures. Fifty-five dogs exhibiting signs of FAS or history of significant FAS in veterinary hospital settings completed the study. Except for those premedicated with trazodone (Group 4), dogs were randomly assigned to 3 treatment groups. Groups 1 (An-shen) and 2 (GB-21) were treated with Aqua-AP bilaterally, while Group 3 served as untreated controls. Stress data, including heart rate, panting respiratory rate, behavior and saliva cortisol concentration were taken at T0 (baseline) and T30 (30 minutes post-treatment). Comparison of group outcome data found that Aqua-AP groups had significant decreases for heart rate (p = 0.004 and p = 0.0005, respectively) and behavior score (p = 0.0002 and p = 0.008, respectively) from T0 to T30, and posttreatment values were not higher than the pharmaceutical-treated subjects (noninferiority). In addition, Group 1 had significant reduction (p = 0.04) in incidence of panting respiratory rate. No significant stress parameter changes were observed in controls. The cortisol concentration change was not significant in any group, but the post-treatment cortisol concentration in both Aqua-AP groups was not greater than the trazodone group (p = 0.004 and p = 0.018, respectively). These results suggest that Aqua-AP at An-shen or GB-21 is effective in mitigating FAS in healthy dogs during routine veterinary examination and demonstrates noninferiority to premedication with trazadone.
Neighborhoods and Health: Assessing “Neighborhood Effects” on Accidental Drug Deaths

ABSTRACT In this paper, I applied criminological theory to the epidemiological understanding of health-related deviant behavior such as problematic drug use. To that end, I built and subsequently tested an epidemiological model informed by macro-level criminological theory that helped explain the spatial distribution of accidental drug deaths across neighborhoods in a heavily suburban area (i.e. unincorporated Miami-Dade County, FL), analyzing toxicology reports from the Miami-Dade County Medical Examiner Department. Estimating a negative binomial analysis of drug abuse that predicted drug-related death rates from 2013 through 2017, I drew insights from the following place-based control theories or perspectives in macro criminology: social disorganization, relative deprivation, immigration revitalization, social institutions, and drug enforcement. I found support for social disorganization theory and the immigration revitalization and social institutions perspectives. Since drug abuse is deviant behavior that is both criminal and health-related, criminology and epidemiology appear to overlap with one another. Epidemiology, the study of disease distribution among populations, would profit by integrating insights from social control theories of criminology. Researchers interested in the social context of neighborhoods and the clustering of drug deaths can apply macrocriminological theory to social epidemiology, which concerns itself with the social determinants of health.
Trusting Difference-in-Differences Estimates More: An Approximate Permutation Test

In economics and business, policy researchers often use observational data and difference-in-differences estimation to test the effectiveness of a policy change. In this context, the model specification and the estimator for standard errors are crucial for correct inferences, given unobserved heterogeneity and correlation across firms and time. Existing literature mainly focuses on the correct size of inferential tests. We suggest a non-parametric test based on the empirical error distribution of the estimated law effect, which we reveal with placebo laws. In comparison to alternative parametric tests, our procedure improves power, under the stringent condition of maintaining a correct size.
Effect of crossflow regulation by varying jet diameters in streamwise direction on jet impingement heat transfer under maximum crossflow condition

ABSTRACT Jet impingement heat transfer has been studied numerically for a maximum crossflow condition using a 3 × 9 array of jets. Five-hole configurations have been studied for jet average Reynolds numbers ranging from 10,000 to 20,000. Crossflow has been mitigated by varying the jet diameters in the streamwise direction to reduce the impact of crossflow on downstream jet impingement. The design criteria for all five configurations were to keep the average of the jet diameters equal to the constant jet diameter configuration (baseline). It has been found that the configuration with increasing and then decreasing jet diameters provided higher levels of heat transfer with more uniform cooling when compared to the traditional constant diameter configuration and other configurations.
Assessing Psychometric Properties of the Behavioral Emotion Regulation Questionnaire in an Iranian Population

Background: The Behavioral Emotion Regulation Questionnaire (BERQ) has been designed to assess the adaptive and maladaptive strategies for emotion regulation. Objectives: The current investigation aimed to study the psychometric properties of the BERQ in a sample of Iranian students. Methods: To assess the psychometric properties of the BERQ (2020 - 2021), 301 students (150 males and 151 females) at Kermanshah University of Medical Sciences (KUMS) were selected using convenience sampling. In addition to the BERQ, the participants completed the Cognitive Emotion Regulation Questionnaire (CERQ), the Penn State Worry Questionnaire (PSWQ), and the Depression Anxiety Stress Scales (DASS). Afterward, Cronbach's alpha coefficient, convergent and divergent validity, and confirmatory factor analysis were calculated and applied using LISREL V 8.80 and SPSS V 20. Results: The results of factor analysis supported the five-factor structure of the BERQ (including seeking distraction, seeking social support, actively approaching, withdrawal, and ignoring) in the Iranian student sample (RMSEA = 0.08, comparative fit index (CFI) = 0.90, normed fit index (NFI) = 0.90). Furthermore, the positive subscales of the BERQ were significantly and positively correlated with the positive cognitive emotion regulation strategies in the CERQ. They also had a significant negative correlation with depression, anxiety, stress, and worry. Moreover, withdrawal and ignoring were significantly and positively correlated with anxiety, stress, worry, depression, and negative emotion regulation strategies of the CERQ (P < 0.05). Conclusions: The Persian version of the BERQ has suitable psychometric properties. This questionnaire could be utilized for assessing the healthy and unhealthy reactions of individuals.
