TikTok as an Information Hodgepodge: Evaluation of the Quality and Reliability of Urinary Tumors Related Content (Preprint)

BACKGROUND With 1.6 billion users in 2021, TikTok has become the world's fastest-growing social media application ever since its first launch. Because of the explosion of information on it during the COVID-19 pandemic, more and more patients search for information on urinary tumors on TikTok. OBJECTIVE We aim to evaluate the quality and reliability of urinary tumor-related videos on TikTok by using robust assessing scales and share our thoughts based on the results for better public health promotion. METHODS We retrieved videos on bladder, prostate, and kidney cancer from TikTok. Each video's length and descriptions, hashtags, number of views/likes/comments, forms of expression, and the uploader's profile were included. Three validated assessment instruments: the Hexagonal Radar Schema, the Health on the Net Code scale, and the DISCERN instrument, were used for evaluating the quality and reliability of the information. All misinformation was counted and categorized. Univariate analysis of variance was performed for analyzing the results. The Post-Hoc least significant difference test was conducted to explore further explanation. RESULTS Out of 167 retrieved videos, only 61 (36.53%) met the inclusion criteria. Amongst them, 36.07% were misinformative, and the most common type was using outdated data. More than half of the videos could provide good (> 1 point) content on the diseases' symptoms and examinations. However, the definition and outcomes were poorly addressed (tied at 21.31 %). The HONcode scale and the DISCERN instrument revealed a consistent conclusion that most videos on TikTok were of poor to mediocre quality. Videos published by media agencies were statistically better than those posted by others in terms of reliability and overall score (P = .003 and .008, respectively). 86.89% of videos had at least two unexplained medical terms. Among them, healthcare professionals like to use professional terms most (mean = 5.28 words). CONCLUSIONS Most videos on urinary tumors on TikTok are of poor to medium quality and reliability. However, videos posted by media agencies enjoyed great public attention and interaction. Medical practitioners could improve the video quality by cooperating with media agencies and avoiding unexplained terminologies.

Development and Initial Validation of a Scale to Measure Cognitive Demands of Flexible Work

With globalization, digitalization, and the spread of information and communication technologies, rules regulating work have been softened or completely abolished. Consequently, employees face additional cognitive demands to plan, structure, and coordinate their work. To capture these demands of contemporary work, we constructed and initially validated the Cognitive Demands of Flexible Work (CODE) scale. The scale comprises four subscales (i.e., structuring of work tasks, planning of working times, planning of working places, and coordinating with others). We initially validated the scale in three independent studies (overall N = 1,129) in German and English. Confirmatory factor analyses supported the four-factor structure, as well as scalar invariance, of the different language versions. Moreover, the subscales showed convergent and divergent validity with related constructs such as requirements for problem solving or autonomy. The criterion validity for emotional exhaustion, engagement, positive work rumination, negative work rumination, and problem-solving pondering suggested that cognitive demands of flexible work can be construed as challenge demands. However, relationships with emotional exhaustion were not significant. Overall, the CODE scale was shown to be a reliable and valid instrument to measure cognitive demands of flexible work.

IMPLEMENTATION AND COMPARISON OF LATTICE MODULE AND DISCONTINUITY FACTORS MODULE IN PROTEUS TOOLSETS

State-of-the-art core nodal diffusion calculation involves the use of assembly discontinuity factor (ADF) to improve computational accuracy by introducing degree of freedom describing the relationship between interfacial discontinuities in nodal calculation [1]. The form of ADF known as the Flux based ADF (FDF) generated from flux information is recommended in the conventional two-level core calculation scheme. The multi-group cross-sections were generated using SCALE 6.2 NEWT and verified with KENO-VI [2]. A lattice module has been created for the high-fidelity neutron transport code MOCEX [3] to generate the group constants and side-independent ADFs. This new capability is verified against the reference code SCALE 6.2 NEWT under both serial and parallel modes. The implementation of ADF is performed in this work and further verified by comparing core keff. The calculation results show that the newly implemented ADF module consistently improved the accuracy of the PROTEUS-NODAL (NODAL) diffusion solver, which will become an affordable candidate for the following research of High-to-Low (Hi2Lo) transport-to-diffusion informing scheme [4].

However, relationships with emotional exhaustion were only significant for one of the four subscales. Overall, the CODE scale was shown to be a reliable and valid instrument to measure cognitive demands of flexible work.

Checking Decimeter Intervals of the Trimble Levelling Rods’ Bar-Code Scale

Russian regulation documents permit using telescopic rods made of duralumin for III and IV class leveling. The authors provided information from the leveling instruction on the need to perform metrological testing the rods before work and during the measurements. The article focuses on two most important checkouts

UNCERTAINTY PROPAGATION FOR LWR BURNUP BENCHMARK USING SAMPLING BASED CODE SCALE/SAMPLER

Sampling based method is adopted in many fields of engineering and it is currently used to propagate uncertainties from physical parameters and from nuclear data, to integral indicators of nuclear systems. The total uncertainty associated with a model simulation is of major importance for safety analysis and to guide vendors about acceptable tolerance limits for nuclear installations parts. This work presents some calculations to propagate uncertainties for a nuclear reactor fuel element modeled in SCALE/TRITON, using the sampling tool SCALE/SAMPLER. Results showed that that the influence of input uncertainties on kinf is more pronounced in the fresh core other than the depleted core and the contribution from studied manufacturing uncertainties is smaller than the contribution of nuclear data uncertainties.
