Bridging Educational Grant in Nursing (BEGIN) students' intentions for retention in long-term, home and community care: A survey protocol.

Retention of nurses in long-term care (LTC) and home and community care (HCC) settings is a growing concern. Previous evidence underscores factors which contribute to nurses' intentions for retention in these sectors. However, perspectives of nursing students preparing to enter the workforce, and their intentions for short-term and long-term retention, remain unknown. This study aims to explore relationships between short-term and long-term intentions for retention with psychological empowerment, work engagement, career commitment, burnout, prosocial motivation, self-care and personal resilience among students enrolled in nursing educational bridging programs supported by the Bridging Educational Grant in Nursing (BEGIN) program in Ontario, Canada. This cross-sectional design study will use an open online survey to investigate perspectives of current nursing students enrolled in educational bridging programs on factors relating to psychological empowerment, work engagement, career commitment, resilience, burnout, prosocial motivation, self-care and intentions for retention. Additionally, the survey will collect demographic information, including age, gender, ethnicity, citizenship, income, family status, nursing role, and years of employment and/or education. Open-ended questions will elicit participants' perspectives on financial considerations for career planning and other factors impacting intentions for retention. Descriptive data will be presented for contextualisation of participants' demographic characteristics to enhance generalisability of the cohort. Descriptive statistics will be used to summarise participants' scores on various assessment measures, as well as their short-term and long-term intentions for retention in LTC and HCC after completion of BEGIN. A Pearson's product moment r correlation will determine relationships between intentions for retention and other measures, and linear regression will determine whether any potential correlations can be explained by regression. This research protocol received ethical approval from a research-intensive university research ethics board (#123211). Findings will be disseminated to nursing knowledge users in LTC and HCC through publications, conferences, social media and newsletters.

Complete Denture Preclinical Training Program and Digital Tools: A Pilot Study.

To determine whether digital training improves conceptual skills acquisition for custom tray fabrication and tooth arrangement in the preclinical curriculum for complete denture fabrication. A crossover design study compared third-year student grades after conventional (manual) and digital training. Half the students were trained with conventional techniques prior to digital, while the other half were trained with digital techniques prior to conventional. The first part of the study (DP1) focused on custom tray fabrication and involved 154 students. The second part (DP2) focused on tooth arrangement with 204 students. The effect of preliminary digital training on conceptual skills was assessed by comparing the results of the students using a Student's t-test. Results were also analyzed by ranking on the students' Perceptual Ability Test (PAT) score. Finally, students' satisfaction with the training was investigated. Students who completed the initial digital session achieved better custom tray fabrication and tooth arrangement in the subsequent manual sessions. For manual laboratory work, the most dexterous students (PAT1 group) demonstrated the best performance. However, PAT2 students had the best performance during the digital sessions during DP1, and PAT1 and PAT2 students had the best performance during the digital sessions during DP2. Additionally, 40% of DP1 and 12% of DP2 students expressed satisfaction with digital sessions. With complementary manual and digital teaching, digital tools may be useful for enhanced student learning. Digital training has contributed to improve results in manual sessions but did not affect student satisfaction and remained a limited tool to detect learning difficulties.

Using Artificial Intelligence to Improve the Accuracy of a Wrist-Worn, Noninvasive Glucose Monitor: A Pilot Study.

Self-monitoring of glucose is important to the successful management of diabetes; however, existing monitoring methods require a degree of invasive measurement which can be unpleasant for users. This study investigates the accuracy of a noninvasive glucose monitoring system that analyses spectral variations in microwave signals. An open-label, pilot design study was conducted with four cohorts (N = 5/cohort). In each session, a dial-resonating sensor (DRS) attached to the wrist automatically collected data every 60 seconds, with a novel artificial intelligence (AI) model converting signal resonance output to a glucose prediction. Plasma glucose was measured in venous blood samples every 5 minutes for Cohorts 1 to 3 and every 10 minutes for Cohort 4. Accuracy was evaluated by calculating the mean absolute relative difference (MARD) between the DRS and plasma glucose values. Accurate plasma glucose predictions were obtained across all four cohorts using a random sampling procedure applied to the full four-cohort data set, with an average MARD of 10.3%. A statistical analysis demonstrates the quality of these predictions, with a surveillance error grid (SEG) plot indicating no data pairs falling into the high-risk zones. These findings show that MARD values approaching accuracies comparable to current commercial alternatives can be obtained from a multiparticipant pilot study with the application of AI. Microwave biosensors and AI models show promise for improving the accuracy and convenience of glucose monitoring systems for people with diabetes.

Examining the impact of design-comparable effect size on the analysis of single-case design in special education.

Initially excluded from many evaluations of education research, single-case designs have recently received wider acceptance within and beyond special education. The growing approval of single-case design has coincided with an increasing departure from convention, such as the visual analysis of results, and the emphasis on effect sizes comparable with those associated with group designs. The use of design-comparable effect sizes by the What Works Clearinghouse has potential implications for the experimental literature in special education, which is largely composed of single-case designs that may not meet the assumptions required for statistical analysis. This study examined the compatibility of single-case design studies appearing in 33 special education journals with the design-comparable effect sizes and related assumptions described by the What Works Clearinghouse. Of the 1,425 randomly selected single-case design articles published from 1999 to 2021, 59.88% did not satisfy assumptions related to design, number of participants, or treatment replications. The rejection rate varied based on journal emphasis, with publications dedicated to students with developmental disabilities losing the largest proportion of articles. A description of the results follows a discussion of the implications for the interpretation of the evidence base. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Toward Reducing Casting Defects via 3D Risers via 3D Sand-Printing: A Simulation Study

AbstractThe 3D sand printing (3DSP) process is a binder jetting class of additive manufacturing process that can incorporate complex 3D mold designs and consolidate cores with intricate features that were previously inaccessible. Prior studies in 3DSP mold design have been shown to improve pouring and filling conditions for sand casting. However, the opportunity to improve casting quality by exploring 3D riser designs during the solidification stage has not yet been explored. In this research, three novel 3D riser geometries—ellipsoid, spherical, and a fusion riser (combination of cylindrical and ellipsoid riser) were investigated. The results were compared to the benchmark cylindrical risers to assess casting performance (e.g., reduction in shrinkage porosity, increase in solidification time). Computational solidification simulations have been presented to evaluate the characteristics of the novel risers for three different metal alloys- nickel aluminum bronze (NAB), low-carbon steel A216 (WCB), and aluminum alloy (A319) alloy. From the results of this research, spherical risers were found to provide 45% yield improvement of for the three alloys studied. In addition, the riser neck diameter using a spherical riser experienced up to 77% reduction when compared to the recommended dimensions from previous literature. Finally, one of the spherical riser designs provided 18% improvement in terms of riser-pipe safety height over the benchmark design. Findings from this research will help metalcasting industries to optimize their riser designs for complex casting geometries by implementing 3D riser geometries (via 3DSP) into traditional mold making for yield improvement and defect-free castings.

Knowledge, Attitude and Practices Regarding Diabetic Foot Care among Diabetic Patients in a Hospital of Rupandehi

INTRODUCTIONDiabetes Mellitus is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Diabetic foot ulcers are common and are estimated to affect about 15% of all individuals with diabetes during their lifetimes. The objective of the study is to assess the knowledge, attitude and practice regarding diabetic foot care among diabetic patients. MATERIAL AND METHODSCross sectional descriptive design study was conducted among 384 diabetic patients selected by using purposive sampling technique. Structured interview questionnare was used for data collection for 6 months periods and was analyzed by using descriptive and interferential statistics with Statistical Package for Social Sciences software version 20. RESULTSThe findings of the study revealed that 23.7% had adequate level of knowledge regarding diabetic foot, 96.9% of the respondents had positive attitude regarding diabetic foot care and 39.0% of the respondents had good practice regarding diabetic foot care. CONCLUSIONBased on the findings, it is concluded that more than three fourth (76.3%) of the diabetic patients had inadequate knowledge regarding diabetic foot. Almost cent percent (96.9%) of the diabetic patients had positive attitude towards the diabetic foot care. More than three fifth (61.0%) of the diabetic patients had poor practices regarding diabetic foot care.

Improving mangoes' productivity and crop water productivity by 24-epibrassinosteroids and hydrogen peroxide under deficit irrigation

In nature, plants are frequently subjected to a wide range of abiotic stresses that drastically reduce crop productivity. Deficit in irrigation is one of the main factors of abiotic stresses that affect agricultural productivity. Nevertheless, not much research has been done on how to use water with brassinosteroids (Br) and hydrogen peroxide (H2O2)in deficit water conditions in order to reach comparatively good values of mango tree growth, productivity, and fruit quality as well as crop water productivity (WPC). A split-plot experiment in a complete randomized block system design study with 3 regulated deficit irrigation levels i.e. 100% IR (Irrigation requirement), 80% IR, and 60% IR was implemented in 2022 and 2023, each irrigation regime was combined with the foliar application of distilled water (control), 1 mg/L Br, 10 mM H2O2, 1 mg/L Br + 10 mM H2O2. Foliar treatments were applied at 3 different phenological stages: flower bud induction and differentiation, full bloom, and beginning of fruit set. The results showed that fruit shape index and acidity significantly improved as irrigation volume increased, however, the proportion of fruit mineral content and fruit chemical characteristics was inversely correlated with the volume of water. Meanwhile, moderate regular deficit irrigation (80% IR) achieved marked increases in leaf minerals and total chlorophyll content, fruit quality, yield, and water use efficiency. Drought stress (60% IR) significantly decreased fruit set, fruit retention, yield traits, and fruit physical and chemical properties, at the same time, significant improvements in the content of stress indicators (proline, total phenols, and carotenoids) were observed compared with control. All treatments with Br and H2O2 alone or in combination under drought stress had a pronounced effect in this regard. Overall, foliar spray of 1 mg/L Br+10 mM H2O2 was the most powerful treatment that emended the unpropitious effect of water stress.

Immersive Virtual Colonography Viewer for Colon Growths Diagnosis: Design and Think-Aloud Study

Desktop-based virtual colonoscopy is a proven and accurate process for identifying colon abnormalities. However, it is time-consuming. Faster, immersive interfaces for virtual colonoscopy are still incipient and need to be better understood. This article introduces a novel design that leverages VR paradigm components to enhance the efficiency and effectiveness of immersive analysis. Our approach contributes a novel tool highlighting unseen areas within the colon via eye-tracking, a flexible navigation approach, and a distinct interface for displaying scans blended with the reconstructed colon surface. The path to evaluating and validating such a tool for clinical settings is arduous. This article contributes a formative evaluation using think-aloud sessions with radiology experts and students. Questions related to colon coverage, diagnostic accuracy, and time to complete are analyzed with different user profiles. Although not aimed at quantitatively measuring performance, the experiment provides lessons learned to guide other researchers in the field.

Educational training and nursing professional self-perception in Mongolia: A prospective observational pre-post design study.

To determine whether professional self-perception of nurses in Mongolia improves following an educational intervention and to identify differences in scores among participant subgroups. A prospective observational pre-post design. Using a convenience sample of 67 nurses in Mongolia in 2019, the Nursing Professional Values Scale-3 instrument was used pre- and post-intervention. Independent and paired sample t-tests were conducted. Data were analysed using IBM SPSS 28.0.1.1 and Stata/SE 16.1. This study complied with the STROBE checklist. Of the 67 nurses, 92.0% were female, mean age was 32.15 years (SD 8.96), 70.0% held a bachelor's degree, 58.0% had 5 or more years' nursing experience and 51.0% were members of a professional nursing organization. After participating in the educational training, nurses reported higher overall professional self-perception as well as across subscales: activism, professionalism and caring. Considering the nursing shortage in lower-middle-income countries, it is important to recognise the influence of nurses' professional self-perception on nursing retention. This study highlights the significant role continuing educational opportunities play in increasing nurses' professional self-perception. It is imperative to explore ways of improving this perception and focusing on subgroups of nurses to help guide the use of limited resources. Further research is necessary to include nurses in other areas of Mongolia. Accurately assessing nursing professional self-perception and providing educational opportunities could improve nursing professional self-perception, nursing satisfaction, patient safety and nursing retention in lower-middle-income countries. What problem did the study address? This study meets the need for current study on the nursing professional self-perception of nursing from the perspective of nurses in Mongolia. It addresses the dangerous nursing shortage in Mongolia by determining if an educational intervention could improve nursing professional self-perception and thus improve nursing job satisfaction and retention. What were the main findings? Mongolian nurses in this study scored in the top quartile of the NPVS-3, indicating a baseline high NPSP. Educational intervention (including translated oral education and written clinical pathways) significantly improved the nurses' professional self-perception. Nurses were eager for training in other clinical and leadership topics. Where and on whom will the research have an impact? This research can be impactful for nurses, nurse leaders and policy makers in low- and lower-middle-income countries. Specifically for nurses in Mongolia, with increasing technologies and services such as cardiac catheterization laboratories becoming available, more education in these nursing specialty areas is imperative. Professional Nursing Organizations are poised to foster more educational offerings to their members and to increase membership. Nursing education provided by international volunteer nurses with Non-Governmental Organizations can improve NPSP in nurses in LMICs. This study complied with the STROBE checklist. No patient or public contribution.

A variable stiffness design method for soft robotic fingers based on grasping force compensation and linearization

Abstract Soft fingers play an increasingly important role in robotic grippers to achieve adaptive grasping with variable stiffness features. Previous studies of soft finger design have primarily focused on the optimization of the structural parameters of existing finger structures, but limited efforts have been put into the design methodology from fundamental grasping mechanisms to finger structures with desired grasping force features. To this aim, a fundamental architecture of soft fingers is proposed for analyzing common soft finger features and the influence of the internal structures on the overall grasping performance. In addition, three general performance metrics are introduced to evaluate the grasping performance of soft finger designs. Then, a novel method is proposed to combine the variable stiffness structure with the fundamental architecture to compensate for the grasping force of the finger and linearization. Subsequently, an embodiment design is proposed with a cantilever spring-based variable stiffness (CSVS) mechanism based on the method, and a multi-objective optimization method is employed to optimize the design. Besides, the CSVS features are analyzed through finite element analysis (FEA), and by comparing the grasping performance between the V-shape finger and the CSVS finger, it is demonstrated that the design method can effectively shorten the pre-grasp stage and linearize the grasping force in the post-grasp stage while reducing the likelihood of sliding friction between the finger and the grasped object. Finally, experiments are conducted to validate the accuracy of the FEA model, the effectiveness of the design methodology, and the adaptability of the CSVS finger.

Prediction of 3D RNA Structures from Sequence Using Energy Landscapes of RNA Dimers: Application to RNA Tetraloops.

Access to the three-dimensional structure of RNA enables an ability to gain a more profound understanding of its biological mechanisms, as well as the ability to design RNA-targeting drugs, which can take advantage of the unique chemical environment imposed by a folded RNA structure. Due to the dynamic and structurally complex properties of RNA, both experimental and traditional computational methods have difficulty in determining RNA's 3D structure. Herein, we introduce TAPERSS (Theoretical Analyses, Prediction, and Evaluation of RNA Structures from Sequence), a physics-based fragment assembly method for predicting 3D RNA structures from sequence. Using a fragment library created using discrete path sampling calculations of RNA dinucleoside monophosphates, TAPERSS can sample the physics-based energy landscapes of any RNA sequence with relatively low computational complexity. We have benchmarked TAPERSS on 21 RNA tetraloops, using a combinatorial algorithm as a proof-of-concept. We show that TAPERSS was successfully able to predict the apo-state structures of all 21 RNA hairpins, with 16 of those structures also having low predicted energies as well. We demonstrate that TAPERSS performs most accurately on GNRA-like tetraloops with mostly stacked loop-nucleotides, while having limited success with more dynamic UNCG and CUYG tetraloops, most likely due to the influence of the RNA force field used to create the fragment library. Moreover, we show that TAPERSS can successfully predict the majority of the experimental non-apo states, highlighting its potential in anticipating biologically significant yet unobserved states. This holds great promise for future applications in drug design and related studies. With discussed improvements and implementation of more efficient sampling algorithms, we believe TAPERSS may serve as a useful tool for a physics-based conformational sampling of large RNA structures.

The Presence of Blood in a Strain Gauge Pressure Transducer Has a Clinical Effect on the Accuracy of Intracranial Pressure Readings.

Patients admitted with cerebral hemorrhage or cerebral edema often undergo external ventricular drain (EVD) placement to monitor and manage intracranial pressure (ICP). A strain gauge transducer accompanies the EVD to convert a pressure signal to an electrical waveform and assign a numeric value to the ICP. This study explored ICP accuracy in the presence of blood and other viscous fluid contaminates in the transducer. Preclinical comparative design study. Laboratory setting using two Natus EVDs, two strain gauge transducers, and a sealed pressure chamber. No human subjects or animal models were used. A control transducer primed with saline was compared with an investigational transducer primed with blood or with saline/glycerol mixtures in mass:mass ratios of 25%, 50%, 75%, and 100% glycerol. Volume in a sealed chamber was manipulated to reflect changes in ICP to explore the impact of contaminates on pressure measurement. From 90 paired observations, ICP readings were statistically significantly different between the control (saline) and experimental (glycerol or blood) transducers. The time to a stable pressure reading was significantly different for saline vs. 25% glycerol (< 0.0005), 50% glycerol (< 0.005), 75% glycerol (< 0.0001), 100% glycerol (< 0.0005), and blood (< 0.0005). A difference in resting stable pressure was observed for saline vs. blood primed transducers (0.041). There are statistically significant and clinically relevant differences in time to a stable pressure reading when contaminates are introduced into a closed drainage system. Changing a transducer based on the presence of blood contaminate should be considered to improve accuracy but must be weighed against the risk of introducing infection.

Taste alteration and its relationship with nutritional status among cancer patients receiving chemotherapy, cross-sectional study

The aim of this study is to determine the prevalence of taste alterations (TAs) during chemotherapy and their association with nutritional status and malnutrition. In addition to the associated factors with TA, including sociodemographic health-related factors and clinical status, and to investigate coping strategies to manage TA. A multicenter cross-sectional design study was conducted on 120 cancer patients aged at least 18 who had been undergoing at least one round of chemotherapy. TAs were evaluated using the chemotherapy-induced taste alteration scale (CiTAS), the malnutrition universal screening tool (MUST) was used for nutritional screening, the antineoplastic side effects scale (ASES) was used for subjective assessment of chemotherapy side effects, and the Charlson comorbidity index (CCI) was used for comorbidity assessment. SPSS21 software was used to analyze the data, and the independent T-test and one-way ANOVA test were used to determine the association between TAs and a variety of related variables. The prevalence of TAs was 98.3%. Among participants, 48.3% were at low risk of malnutrition, 20% at medium risk, and 31.7% at high risk. Malnutrition risk was associated with taste disorders (p&lt;0.05). Patients’ age, gender, educational level, and physical status were associated with TAs (p&lt;0.05). Type of cancer, chemotherapy regimen, and number of chemotherapy cycles were also associated with TAs (p&lt;0.05). A variety of antineoplastic side effects were associated with TAs (p&lt;0.05), including nausea, vomiting, dry mouth, sore mouth and throat, excessive thirst, swallowing difficulty, appetite changes, weight loss, dizziness, lack of energy, disturbed sleep, anxiety, and difficulty concentrating. TAs were associated with an increased number of comorbidities, and individuals with diabetes, pulmonary diseases, and hypertension were associated with TAs (P&lt;0.05). Patients in this study rarely practice self-management strategies to cope with TAs. A high prevalence (98.3%) of TAs in cancer patients receiving chemotherapy was found, and it was linked to a variety of negative outcomes. Chemotherapy-induced TAs are an underestimated side effect that requires more attention from patients and health care providers.

Design and Experimental Study of an Embedded Controller for a Model-Based Controllable Pitch Propeller

The controllable pitch propeller hydraulic system has high constraints and nonlinearity. Due to these inherent deficiencies, the proportional–integral–derivative (PID) control algorithm cannot meet the control accuracy requirements of nonlinear systems. A control law based on a model predictive control (MPC) algorithm is designed in this paper. The gain parameters of the predictive control are optimized. The MPC and PID control systems are compared and simulated to verify the MPC controller’s effectiveness. Subsequently, the embedded controller of a controllable pitch propeller is developed. The support package for the embedded circuit board target containing an underlying driver for each interface is written by introducing the C-MEX S-Function and TLC programming language. A semi-physical simulation experiment is performed. The results show that the established controllable pitch propeller with an embedded controller displays reliable running performance, good anti-interference, and the capacity to fulfill the control function of the pitch propeller under various working conditions.

Repairing Host Damage Caused by Tobacco Mosaic Virus Stress: Design, Synthesis, and Mechanism Study of Novel Oxadiazole and Arylhydrazone Derivatives.

Tobacco mosaic virus (TMV), as one of the most traditional and extensive biological stresses, poses a serious threat to plant growth and development. In this work, a series of 1-phenyl/tertbutyl-5-amino-4-pyrazole oxadiazole and arylhydrazone derivatives was synthesized. Bioassay evaluation demonstrated that the title compounds (P1-P18) without a "thioether bond" lost their anti-TMV activity, while some of the ring-opening arylhydrazone compounds exhibited superior in vivo activity against TMV in tobacco. The EC50 value of title compound T8 for curative activity was 139 μg/mL, similar to that of ningnanmycin (NNM) (EC50 = 152 μg/mL). Safety analysis revealed that compound T8 had no adverse effects on plant growth or seed germination at a concentration of 250 μg/mL. Morphological observation revealed that compound T8 could restore the leaf tissue of a TMV-stressed host and the leaf stomatal aperture to normal. A mechanism study further revealed that compound T8 not only restored the photosynthetic and growth ability of the damaged host to normal levels but also enhanced catalase (CAT) activity and reduced the content of malondialdehyde (MDA) and hydrogen peroxide (H2O2) in the damaged host, thereby reducing the oxidation damage to the host. TMV-green fluorescent protein (GFP) experiments further demonstrated that compound T8 not only slowed the transmission speed of TMV in the host but also inhibited its reproduction. All of the experimental results demonstrated that compound T8 could reduce the oxidative damage caused by TMV stress and regulate the photosynthetic ability of the host, achieving the ability to repair damage, to make the plant grow normally.

Pneumococcal Vaccination Effectiveness (PCV13 and PPSV23) in Individuals With and Without Reduced Kidney Function: A Test-Negative Design Study

Abstract Background Streptococcal Pneumoniae vaccination effectiveness (VE) in individuals with reduced kidney function is unknown. We estimated pneumococcal conjugate vaccine (PCV13), pneumococcal polysaccharide vaccine (PPSV23), and combined PCV13 &amp; PPSV23 effectiveness against pneumococcal disease in individuals with and without reduced estimated glomerular filtration rate (eGFR). Methods All eligible individuals (case and controls) were adults (aged ≥18) hospitalized within Geisinger Health System and required to have S. Pneumoniae urinary antigen testing (ie. test negative design). Vaccination records were obtained from the electronic health record and statewide vaccination registry. After controlling for the probability of receiving a pneumococcal vaccine, we used multivariable logistic regression models to estimate the odds ratios (ORs) of vaccination between those who did and did not meet the S. Pneumoniae case definition. VE was calculated as (1 – OR) * 100%. Results There were 180 cases and 3,889 controls (mean age 69 years, female 48%, White 97%, mean eGFR 71). The adjusted population PCV13 VE was 40% (95% CI 13 – 58%), and combination PCV13 &amp; PPSV23 was 40% (95% CI 13 - 59%). PPSV23 VE was -4.1% (95% CI -58 – 31%). Stratified by eGFR, adjusted PCV13 VE was consistent in eGFR ≥60 (VE 38% [95% CI 3.2 - 61%]) and 30-59 (VE 61% [95% CI 25 – 80%]) without significant interaction. VE was not calculable for eGFR &amp;lt;30 due to small sample size. Conclusion PCV13 vaccination was associated with reduced risk of S. Pneumoniae hospitalization in individuals with a reduced eGFR (30 – 59 mL/min/1.73m2).

EmoVis: exploring data-enabled analogue journaling to promote self-reflection for mental wellness among college students

ABSTRACT College students are known to face many stressors, making them one of the most vulnerable groups to mental disorders. To tackle such an issue, this paper presents a design study that investigated data-enabled analogue journaling (DEAJ) to help college students improve their mental wellness through paper-based self-reflection aided by automatic self-tracking. Specifically, based on several design iterations we developed a DEAJ tool, called EmoVis, which could generate a printed visualisation based on daily physiological data and event tags to support doodling or structured writing in analogue journaling for everyday stress management. We conducted a six-day mixed methods field study with 32 college students to evaluate the effectiveness and user experience of EmoVis. Results suggested that EmoVis can significantly improve the engagement and need for self-reflection due to context-based reflection and data-enabled exploratory journaling. Furthermore, the doodling canvas was experienced as a joyful tool for mindfulness and creative DEAJ, while reflecting with a writing template was perceived as efficient. The paper concludes with a discussion of the implications of DEAJ approaches for daily stress coping in students’ college life.
