Central tendency and serial dependence in vestibular path integration.

Path integration, the process of updating one's position using successive self-motion signals, has previously been studied using visual distance reproduction tasks in which optic flow patterns provide information about traveled distance. These studies have reported that reproduced distances show two types of systematic biases: central tendency and serial dependence. In the present study, we investigated whether these biases are also present in vestibular path integration. Participants were seated on a linear motion platform and performed a distance reproduction task in total darkness. The platform first passively moved the participant a pre-defined stimulus distance which they then actively reproduced by steering the platform back the same distance. Stimulus distances were sampled from short- and long-distance probability distributions and presented in either a randomized order or in separate blocks to study the effect of presentation context. Similar to the effects observed in visual path integration, we found that reproduced distances showed an overall positive central tendency effect as well as a positive, attractive serial dependence effect. Furthermore, reproduction behavior was affected by presentation context. These results were mostly consistent with predictions of a Bayesian Kalman-filter model, originally proposed for visual path integration.

Whether the potential degree of cervical instability and cervical muscle degeneration in patients with cervical spondylosis radicular affect the efficacy of cervical traction.

To explore whether the potential instability of the cervical spine and cervical muscle degeneration in patients with cervical spondylotic radiculopathy (CSR) affect the efficacy of cervical traction, and whether cervical traction can aggravate the potential instability of the cervical spine. We divided the 113 recruited CRS patients into three groups based on the differences in horizontal displacement and abnormal angle, and measured the degree of cervical muscle degeneration in the patients through MRI. Considering functional scores, VAS, NDI and PCS scores of the three groups post-treatment were significantly improved. Through the intergroup analysis, we found that the improvement in functional scores in the mild and moderate instability trend groups was better than that in the severe group. Through MRI measurements, we found that the degree of cervical muscle degeneration was significantly increased in the severe instability trend group. Regarding the changes in X-Ray imaging parameters pre- and post-treatment, no significant differences were observed pre- and post-treatment. For patients with CSR, the more serious their predisposition for cervical instability was, the more severe the degree of cervical muscle degeneration was, which means the worse the curative effect was, but cervical traction did not aggravate the potential degree of cervical instability.

Approach Bias and Tobacco Craving as Mechanisms of the Effect of Approach Bias Retraining on Smoking Cessation.

INTRODUCTION: Approach bias, the automatic tendency to advance toward, rather than move away from appetitive cues, has been associated with greater tobacco cravings, dependence, and likelihood of smoking relapse. Approach bias retraining (ABR) has emerged as one way to reduce approach bias and promote avoidance toward smoking cues. Yet, additional research is needed to identify the mechanisms that may help explain the effect of ABR on smoking cessation. METHODS: The current study uses data collected as part of a randomized controlled trial to test two unique mechanisms of action ([1] approach bias and [2] tobacco craving) for the efficacy of standard smoking cessation treatment (ST) augmented by ABR on smoking abstinence. Participants were 96 adult daily smokers (Mage=43.1, SD=10.7) motivated to quit smoking. RESULTS: Results showed that lower approach bias and lower cravings at a treatment session were significantly related to next session smoking abstinence (p's<.018). Further, deviations in approach bias partially mediated the effect of ABR on smoking abstinence (ab=-12.17, 95%CI: [-29.67, -0.53]). However, deviations in tobacco craving did not mediate this relation (ab=.40, 95%CI: [-.27, 1.34]). CONCLUSIONS: The current findings add to extant literature by identifying approach bias as a mechanism of action of the effect of ABR on smoking abstinence during smoking cessation treatment. IMPLICATIONS: The current study adds to our knowledge on the effectiveness of approach bias retraining (ABR) as a part of smoking cessation treatment. Results indicate that reductions in approach bias partially mediate the effect of ABR on smoking abstinence. These findings are consistent with previous research on alcohol-dependent adults and underline the potential of ABR to reduce approach bias and promote smoking cessation among smokers. Such findings could inform the development of future research exploring more targeted and effective smoking cessation interventions, ultimately improving outcomes for individuals attempting to quit smoking.

Prediction of childbearing tendency in women on the verge of marriage using machine learning techniques.

The declining fertility rate and increasing marriage age among girls pose challenges for policymakers, leading to issues such as population decline, higher social and economic costs, and reduced labor productivity. Using machine learning (ML) techniques to predict the desire to have children can offer a promising solution to address these challenges. Therefore, this study aimed to predict the childbearing tendency in women on the verge of marriage using ML techniques. Data from 252 participants (203 expressing a "desire to have children" and 49 indicating "reluctance to have children") in Abadan, and Khorramshahr cities (Khuzestan Province, Iran) was analyzed. Seven ML algorithms, including multilayer perceptron (MLP), support vector machine (SVM), logistic regression (LR), random forest (RF), J48 decision tree, Naive Bayes (NB), and K-nearest neighbors (KNN), were employed. The performance of these algorithms was assessed using metrics derived from the confusion matrix. The RF algorithm showed superior performance, with the highest sensitivity (99.5%), specificity (95.6%), and receiver operating characteristic curve (90.1%) values. Meanwhile, MLP emerged as the top-performing algorithm, showcasing the best overall performance in accuracy (77.75%) and precision (81.8%) compared to other algorithms. Factors such as age of marriage, place of residence, and strength of the family center with the birth of a child were the most effective predictors of a woman's desire to have children. Conversely, the number of daughters, the wife's ethnicity, and the spouse's ownership of assets such as cars and houses were among the least important factors in predicting this desire. ML algorithms exhibit excellent predictive capabilities for childbearing tendencies in women on the verge of marriage, highlighting their remarkable effectiveness. This capacity to offer accurate prognoses holds significant promise for advancing research in this field.

The role of attentional control in moderating attentional bias towards game-related stimuli in individuals with a high tendency for internet gaming addiction.

Background: The aim of this study was to elucidate individual difference factors that modulate the attentional processing of game stimuli to explain the heterogeneity of extant findings. The current study examined whether individual differences in components of attentional control (AC-shifting and AC-focusing) moderated the link between internet gaming addiction symptom and attentional engagement to and disengagement biases from game-relevant cues. Methods: A total of 75 male undergraduate students who have played League of Legend (LOL) for more than 2 years completed well-established self-report questionnaires of internet gaming disorder symptoms and attentional control. The attentional bias toward game stimuli was measured for attentional engagement and disengagement using the attentional response to the distal vs. proximal emotional information (ARDPEI) task. Results: The results revealed that attentional control was a significant moderator of the relationship between internet game addiction symptoms and attentional disengagement bias. Further analyses revealed a positive relationship between internet game addiction symptoms and attentional disengagement bias only among those with low levels of AC-shifting ability. Contrary to our expectations, AC-shifting also moderated the relationship between internet gaming disorder and attentional engagement bias. The positive relationship between internet game addiction symptoms and attentional engagement bias only appeared among those with low levels of AC-shifting ability. Individual differences in AC-focusing did not moderate the relationship between internet gaming disorder and any attentional bias. Conclusion: This study confirmed that the greater the symptoms of game addiction, the stronger the attentional bias, especially in individuals with low AC-shifting ability. Therefore, it is necessary to examine sub-factors of AC in understanding the nature of attentional bias mechanisms in the development of internet game addiction and consider it as a psychological intervention to improve attentional bias.

The Impact of Research Pressure on Depression Tendency among Chinese Doctoral Students: The Mediating Effect of Familial Financial Support.

OBJECTIVE: This study aims to explore the impact of research pressure on depression tendency among Chinese doctoral students and analyze the mediating effect of familial financial support in this relationship. METHODS: Based on the ecological systems theory, this study employs a mediating effect model and OLS regression model for empirical analysis. Through an online questionnaire, 2815 valid data from Chinese doctoral students were successfully collected. CONCLUSION: The study finds that research pressure has a significant positive impact on depression tendency among doctoral students (t = 18.347, p < 0.01). Married doctoral students show relatively lower depression tendency, indicating a negative impact of marital status on depression tendency (t = 12.579, p < 0.01). In terms of gender, female doctoral students are more prone to depression compared to their male counterparts (t = -2.921, p < 0.01). Additionally, as the doctoral year progresses, depression tendency also tends to increase (t = 3.690, p < 0.01). Importantly, familial financial support is proven to be a significant mediator between research pressure and depression tendency, explaining 32.116% of the relationship. SUGGESTION: This study not only provides a multi-dimensional perspective for understanding the mental health issues of doctoral students but also offers a scientific basis for universities and related educational departments to formulate more precise mental health intervention strategies.

Psychological resilience is positively correlated with Habenula volume.

BACKGROUND: Psychological resilience is defined as the process and outcome of individuals' successful adaptation to challenging life experiences. The Habenula (Hb) is known to be involved in the stress response; however, the relationship between Hb volume and resilience in humans remains unclear. This study investigated the correlation among resilience, Hb volume, and depressive tendencies in adults. METHODS: Hb volumes were assessed using deep learning techniques applied to 110 healthy participants. Resilience and depression were evaluated using the Connor-Davidson Resilience Scale and Beck Depression Inventory-II, respectively. We examined the relationship between Hb volume and resilience and assessed the mediating effects of resilience on the relationship between Hb volume and depressive tendencies. RESULTS: Correlation analysis revealed a positive correlation between resilience and Hb volume (partial r = 0.176, p = 0.001), which was more pronounced in women (partial r = 0.353, p = 0.003). Hb volumes on the left and right sides exhibited significant lateralization (LI = 0.031, 95 % CI = [0.016, 0.046]). Despite Hb asymmetry, lateralization was not significantly associated with resilience. The mediation analysis shows significant indirect effect of resilience on the relationship between Hb volume and depressive tendencies (ß = -0.093, 95%CI = [-0.189, -0.019]). CONCLUSION: This study found that populations with lower resilience have smaller Hb volume. Previous research has shown that Hb volume decreased with the increasing severity of depression symptoms in patients. Our findings support this view and extend it to a population that has not been clinically diagnosed with depression. Additionally, we found that psychological resilience can be predicted by Hb volume and may serve as a mediating factor indirectly affecting depressive tendencies, even in healthy individuals. LIMITATIONS: Due to its cross-sectional design, this study was unable to analyze dynamic changes in Hb volume during the process of resilience adaptation.

Validation and Measurement Invariance of the Tendency to Avoid Physical Activity and Sport Scale (TAPAS) Among Thai Young Adults.

Examining ways of reducing physical inactivity has been at the forefront of public health research. Moreover, valid and reliable scales are needed to objectively assess physical activity (PA) avoidance. Previous research has shown that experiencing weight stigma and physical appearance-related concerns are associated with physical inactivity. However, there is currently no Thai instrument that assesses physical inactivity in relation to weight stigma. Therefore, the present study examined the psychometric properties of the Thai version of the Tendency to Avoid Physical Activity and Sport Scale (TAPAS). Thai university students (N = 612) recruited via convenience sampling completed an online survey using SurveyMonkey between September 2022 and January 2023. Confirmatory factor analysis (CFA), multigroup CFA, and Pearson correlations (between TAPAS scores, age, body mass index, and time spent exercising) were used to analyze the data. The CFA showed robust psychometric properties for the Thai version of TAPAS regarding its unidimensional structure. The TAPAS was measurement invariant across sex, weight status, and daily hours of exercise. However, no significant Pearson correlations were found. In general, the results showed that the TAPAS is a good scale for assessing PA avoidance among Thai young adults across different sexes, weight status, and daily hours of exercise.

Who stays? Who goes? Motivation and tendency to drop out in music schools.

Based on self-determination theory, this study examined the extent to which the satisfaction of the basic psychological needs for autonomy, competence, and social relatedness in instrumental lessons explain the quality and quantity of motivation, which are responsible for persistence and dropout in music schools. This study also investigated whether parental involvement contributes to dropout. A total of 140 music students from Austria (37.16% male, 62.1% female, 0.8% diverse) were surveyed using a quantitative questionnaire. The central variables are the tendency to dropout (dependent variable) and, as predictors, the motivational regulation styles, the satisfaction of basic psychological needs in the classroom and parental involvement. The results of a structural equation model indicated that satisfaction of basic needs in class and parental involvement, mediated by motivation, predicted dropout tendencies. Autonomous motivation in lessons is negatively associated and controlled motivation is positively associated with the tendency to drop out of music schools. Satisfaction of basic psychological needs during lessons and parental involvement predicts autonomous motivation. However, basic psychological needs cannot predict controlled motivation but parental involvement can predict controlled motivation to a limited extent. Finally, this study emphasizes the practical importance of need satisfaction and parental involvement in motivation and continuing to play a musical instrument.

Adiposity influences intraindividual variability in behavioral and neuroelectric indices of attentional inhibition.

While overweight or obesity are thought to affect over 70% of the US population, the effects of adiposity on neurocognitive efficiency and stability remain unclear. Intra-individual variability or trial-to-trial variability (IIV) could provide insights into the influence of adiposity on neurophysiological stability. However, previous work examining the association between adiposity and IIV of cognitive outcomes is limited. Thus, this study examined the association between whole-body fat (%BF) and central tendency and IIV metrics of behavioral performance and event-related potentials. Adults (n = 320; 19-64 yrs) completed the Flanker task to assess attentional inhibition with concurrent electroencephalogram recordings to examine the N2 and P3b components. In addition to central tendency outcomes typically reported (i.e., mean accuracy and reaction time [RT]), dispersion outcomes (e.g., standard deviation [SD] of RT, P3b latency, N2 latency, etc.) were also extracted. Upon controlling for age and sex, %BF was inversely associated with (congruent: ß = -.18, p = .016; incongruent: ß = -.23, p < .001) accuracy. Increasing %BF was related to greater RT SD (congruent: ß = .13, p = .032; incongruent: ß = .23, p < .001). Furthermore, increased %BF was associated with slower P3b latencies (congruent: ß = .21, p = .003; incongruent: ß = .18, p = .010), and greater incongruent N2 (ß = .16, p = .017) and P3b (ß = .16, p = .025) latency SD. These findings suggest adiposity exerts a generalized negative influence on attentional inhibition for both measures of central tendency and dispersion across behavioral and neuroelectric indices.

Inspired to act: motivational effects of being moved by love and willpower.

ABSTRACTPeople can be moved and touched by exceptional closeness between people or by outstanding willpower. We investigated the causal effect of these feelings on motivations. We based our research on the previously identified phenomenon that feelings of being moved are stronger in unfavourable circumstances (e.g. psychological closeness after conflict, high achievement against all odds). In two studies in the US (N1 = 136) and in Germany (N2 = 161), we independently varied context (love vs. willpower) and circumstances (favourable vs. unfavourable) in short stories and assessed feelings of being moved as well as the motivation to show love and the motivation to show willpower after each story. In both contexts and consistent across the two studies, unfavourable circumstances elicited stronger motivations to show love as well as stronger motivations to show willpower. Multilevel mediation modelling revealed that these effects were mediated by feelings of being moved. This indicates that feelings of being moved enhance pro-social as well as achievement-related motivations.

Mobile phone short video use negatively impacts attention functions: an EEG study.

The pervasive nature of short-form video platforms has seamlessly integrated into daily routines, yet it is important to recognize their potential adverse effects on both physical and mental health. Prior research has identified a detrimental impact of excessive short-form video consumption on attentional behavior, but the underlying neural mechanisms remain unexplored. In the current study, we aimed to investigate the effect of short-form video use on attentional functions, measured through the attention network test (ANT). A total of 48 participants, consisting of 35 females and 13 males, with a mean age of 21.8 years, were recruited. The mobile phone short video addiction tendency questionnaire (MPSVATQ) and self-control scale (SCS) were conducted to assess the short video usage behavior and self-control ability. Electroencephalogram (EEG) data were recorded during the completion of the ANT task. The correlation analysis showed a significant negative relationship between MPSVATQ and theta power index reflecting the executive control in the prefrontal region (r = -0.395, p = 0.007), this result was not observed by using theta power index of the resting-state EEG data. Furthermore, a significant negative correlation was identified between MPSVATQ and SCS outcomes (r = -0.320, p = 0.026). These results suggest that an increased tendency toward mobile phone short video addiction could negatively impact self-control and diminish executive control within the realm of attentional functions. This study sheds light on the adverse consequences stemming from short video consumption and underscores the importance of developing interventions to mitigate short video addiction.

The impact of negative urgency on implicit mobile phone addiction tendency among college freshmen in the context of social exclusion.

Purpose: The purpose of this study is to investigate the impact of negative urgency on implicit mobile phone addiction tendency among college freshmen, and to observe whether social exclusion situations affect the relationship between negative urgency and implicit mobile phone addiction tendency. Methods: The UPPS-P Impulsive Behavior Scale was used to screen 575 freshmen from a certain university. The experiment utilized a GO/NO-GO paradigm. Experiment 1 employed a 2 (negative urgency group: high negative urgency group, low negative urgency group) × 2 (word type: phone related words, phone non-related words) two-factor mixed experimental design. Experiment 2 employed a 2 (negative urgency group: high negative urgency group, low negative urgency group) × 2 (social exclusion type: priming group, non-priming group) × 2 (word type: phone related words, phone non-related words) three-factor mixed experimental design. Results: Experiment 1 results showed a significant main effect of negative urgency group and a significant interaction effect between negative urgency group and word type. Experiment 2 results demonstrated a significant main effect of negative urgency group and a significant main effect of social exclusion type. There was a significant interaction effect between word type and social exclusion type, as well as between word type and negative urgency group. The three-way interaction effect among negative urgency group, word type, and social exclusion type was significant. Conclusion: College freshmen with high negative urgency exhibit a higher tendency toward implicit mobile phone addiction. In social exclusion situations, college freshmen show a higher tendency toward implicit smartphone addiction. Social exclusion situations and negative urgency jointly influence the implicit mobile phone addiction tendency of college freshmen.

The mediating role of pediatric nursing competence in the relationship between pediatric drug administration self-efficacy and medical error tendency in nursing students.

AIM: This study was conducted to determine the mediating role of pediatric nursing competence in the relationship between self-efficacy in pediatric drug administration and medical error tendency in nursing students. BACKGROUND: The self-efficacy of nursing students towards drug administration knowledge and practices is one of the determinants of achieving the goals of nursing education programs related to drug administration. DESIGN: The sample of the descriptive and correlational study consisted of a total of 303 3rd and 4th-year students taking the Pediatric Health and Diseases Nursing course at the Department of Nursing. Data were collected using the Pediatric Nursing Competency Scale (PNCS), the Medication Administration Self-Efficacy Scale in Children for Nursing Students (MASSC) and the Medical Errors Tendency Scale (METS). Pearson correlation analysis, linear regression analysis, independent groups t-test, one-way analysis of variance (ANOVA) and post hoc (Tukey, LSD) test were used to analyze the data. In addition, hierarchical regression analyses regarding the mediation effect were performed using PROCESS Model 4 developed by Hayes (2013) for SPSS. RESULTS: When the correlation levels between the total scores of MASSC, PNSC and METS were analyzed, a positive moderate correlation was found between PNSC and MASSC total scores, a positive weak correlation was found between METS and MASSC total scores and a positive weak correlation was found between METS and PNSC total scores (p<0.05). As a result of the analysis, the model was found to be significant and the total change in METS was explained by 17.3 % of the total change in METS (F=63.289;p=0.000). It was found that PNSC was a partial mediator variable between MASSC and METS. CONCLUSION: As a result of the study, it was determined that pediatric nursing competence had a partial mediating role in the relationship between pediatric drug administration self-efficacy and medical error tendency in nursing students.

Comparative study on emotional behavior and parental job stress of only-child and non-only-child preschool children.

BACKGROUND: Studies have revealed that Children's psychological, behavioral, and emotional problems are easily influenced by the family environment. In recent years, the family structure in China has undergone significant changes, with more families having two or three children. AIM: To explore the relationship between emotional behavior and parental job stress in only preschool and non-only preschool children. METHODS: Children aged 3-6 in kindergartens in four main urban areas of Shijiazhuang were selected by stratified sampling for a questionnaire and divided into only and non-only child groups. Their emotional behaviors and parental pressure were compared. Only and non-only children were paired in a 1:1 ratio by class and age (difference less than or equal to 6 months), and the matched data were compared. The relationship between children's emotional behavior and parents' job stress before and after matching was analyzed. RESULTS: Before matching, the mother's occupation, children's personality characteristics, and children's rearing patterns differed between the groups (P < 0.05). After matching 550 pairs, differences in the children's parenting styles remained. There were significant differences in children's gender and parents' attitudes toward children between the two groups. The Strengths and Difficulties Questionnaire (SDQ) scores of children in the only child group and the Parenting Stress Index-Short Form (PSI-SF) scores of parents were significantly lower than those in the non-only child group (P < 0.05). Pearson's correlation analysis showed that after matching, there was a positive correlation between children's parenting style and parents' attitudes toward their children (r = 0.096, P < 0.01), and the PSI-SF score was positively correlated with children's gender, parents' attitudes toward their children, and SDQ scores (r = 0.077, 0.193, 0.172, 0.222). CONCLUSION: Preschool children's emotional behavior and parental pressure were significantly higher in multi-child families. Parental pressure in differently structured families was associated with many factors, and preschool children's emotional behavior was positively correlated with parental pressure.

[Comparison of 5-year survival rate and analysis of prognostic factors influencing the prognosis of adenoid cystic carcinoma and squamous cell carcinoma of the maxillary sinus: based on the SEER database].

Objective:To analyze the difference in 5-year survival between maxillary sinus adenoidal cystic carcinoma（maxillary sinus adenoid cystic carcinoma, MSACC） and squamous cell carcinoma（maxillary sinus squamous cell carcinoma, MSSCC） using the National Cancer Institute's Surveillance, Epidemiology, and End. Results:database（SEER） and to explore the factors associated with the prognosis of the two tumors. Methods:The data of 161 patients with MSACC and 929 patients with MSSCC were collected from SEER database, and the 5-year overall survival rate（OS） and tumor specific survival rate（CSS） were compared between the two groups before and after propensity score matching. The forest map of multivariate Cox proportional hazard regression model was established to analyze the prognostic factors affecting the survival rate of patients with MSACC and MSSCC. Results:There were statistical differences in 5-year OS and CSS between MSACC and MSSCC before and after propensity score matching（P<0.001）. Multivariate regression analysis showed that age, side of the disease, lymph node metastasis, operation and radiotherapy were the influencing factors of OS in MSACC, while age and operation were the influencing factors of CSS. Age, race, T grade, lymph node metastasis, systemic metastasis, surgery, radiotherapy and chemotherapy are the influencing factors of OS of MSSCC. Age, T grade, lymph node metastasis, systemic metastasis, surgery, radiotherapy and chemotherapy are the influencing factors of CSS. Conclusion:The 5-year survival rate of MSACC is higher than that of MSSCC. Surgery plays a positive role in the prognosis of the two kinds of tumors. The analysis results can provide some reference for their survival expectations and treatment choices.

Propensity Score Matching Analysis of the Influence of Waiting Time Satisfaction on Community Resident's Satisfaction With Medical Institutions: An Extensive Survey of Outpatient Population in Shantou City of Southern China.

OBJECTIVE: This study was designed to perform a nuanced analysis of the multifaceted association between community residents' satisfaction and their perceived satisfaction concerning the visit duration at medical facilities, that could be harnessed to enhance and streamline the process of hierarchical diagnosis and treatment, thereby augmenting healthcare outcomes and patient experiences. METHODS: Respondents who had utilized services from medical institutions were invited to fill out questionnaires by scanning QR codes. Additionally, surveys also distributed questionnaires through WeChat groups of community residents in densely populated areas of the community, as well as WeChat groups for patients who had previously visited local hospitals. To balance differences between groups, propensity score matching was applied to analyze the contrast between residents satisfied and dissatisfied with their medical visits. After eliminating the interference of confounding factors, a comparative analysis was conducted on the relationship between resident satisfaction and medical institution experience.After eliminating the interference of confounding factors, a comparative analysis was conducted to delve deeply into the relationship between residents' satisfaction and their experiences at medical facilities. RESULTS: The study incorporated a large dataset encompassing 2356 community residents. Upon successful propensity score matching, logistic regression analysis elucidated several determinants of overall resident satisfaction. Notably, the grade of the medical institution (χ2 = 8.226, P < .05), satisfaction with the time invested in the registration process (χ2 = 11.04, P < .05), satisfaction with the waiting duration for consultation (χ2 = 15.759, P < .05), and satisfaction with the travel time to the hospital (χ2 = 45.157, P < .05) each exerted significant influence on the holistic satisfaction of residents with their medical experience. CONCLUSION: Factors such as the grade of the medical institution, satisfaction related to registration and waiting durations, and travel time to the hospital emerged as crucial determinants shaping community residents' holistic satisfaction with their medical encounters. These findings underscore the exigency for strategic allocation and optimization of medical resources, refinement of the classification system, and enhancement of public health education on the graded diagnosis and treatment schema. The study also demonstrates the value of employing advanced propensity score matching and predictive modelling techniques in health services research.

Mutual communication intervention for colorectal cancer patient-spousal caregiver dyads: A randomized controlled trial.

OBJECTIVE: Gender could impact the psychosocial outcomes and coping strategies of cancer patients and their spousal caregivers (SCs). This study aims to develop a gender-concerned program for colorectal cancer (CRC) couple-based mutual communication intervention (MCI) and to assess its effectiveness on the intra-couple relationship and the individual functions of the partners. DESIGN: A randomized clinical trial with two study groups was utilized. METHODS: A total of 144 CRC patients and their SCs were randomly assigned to either MCI or usual care (UC) groups, and all of them were required to complete the measurements at baseline and post-intervention. The primary outcome was for mutual communication, and the secondary outcomes included dyadic coping, relationship satisfaction, anxiety, depression, benefit finding and quality of life. The data were analysed by multi-level modelling. RESULTS: The MCI program was feasible and acceptable for Chinese CRC couples and was effective for the improvement of the intra-couple relationship and the individual functions of each partner. CRC patients showed more improvement in mutual communication and dyadic coping than their SCs in the MCI group. Also, this intervention effectiveness was found to be independent of gender. CONCLUSIONS: The MCI program is beneficial for Chinese CRC couple's adaptation outcomes. This suggests that clinical medical staff should consider the gender tendency during the implementation of interventions. More researches are needed to extend the application of the MCI program to different participants (e.g. patients with the diagnosis of other types of cancer and their SCs).

Utilization of abandoned oil well logs and seismic data for modeling and assessing deep geothermal energy resources: A case study.

Hammam Faraun (HF) geothermal site in Egypt shows potential for addressing energy demand and fossil fuel shortages. This study utilizes abandoned oil well logs, seismic data, and surface geology to assess HF geothermal energy resources. Seismic interpretation identified a significant clysmic fault parallel to Hammam Faraun fault (HFF), named CLB fault. The two faults together create a renewable geothermal cycle through circulation of mixed formation-sea waters. Petrophysics revealed two main geothermal reservoirs: the Nubian sandstone reservoir and the Eocene Thebes carbonate reservoir with water saturation values approaching 100 %. Corrected borehole temperatures indicated reservoir temperatures around 120 °C and 140 °C for the Thebes and Nubian reservoirs, respectively. Fracture analysis and stress state provided insights into subsurface fractures. A geomechanical model demonstrated the impact of different stresses and pore pressure on geothermal fluid flow. NE-SW oriented fractures showed a higher dilation tendency due to aquathermal expansion. The integrated conceptual geothermal model suggested a magma chamber beneath HF as the heat source, related to Oligo-Miocene volcanic activity. The breached relay ramp and fault-related open fracture system serve as pathways for geothermal fluids. Evaluation of the geothermal potential utilized volumetric calculations and Monte Carlo simulation. The estimated hot water volumes were 1.72 km3, 4.242 km3, and 5.332 km3 for the Nubian reservoir in the onshore part, Thebes reservoir in the offshore part, and Nubian reservoir in the offshore part, respectively. The results indicate a medium enthalpy resource suitable for electricity generation using a Kalina geothermal power plant. The predicted geothermal power output is promising, with an average power output of 9.64 MWe, 21.38 MWe, and 43.76 MWe for the Nubian reservoir in the onshore part, Thebes reservoir in the offshore part, and Nubian reservoir in the offshore part, respectively. These outputs can potentially supply electricity to approximately 12,000, 29,000 and 53,000 households, respectively.

Evaluating the effects of action learning on the research competency of undergraduate nursing students: A mixed-methods study.

BACKGROUND: Research skills in nursing are crucial for guiding evidence-based practice and enhancing health care. However, undergraduate nursing students often encounter challenges in skill development because of curriculum constraints that prioritize clinical education. Bridging this skill gap is imperative for preparing students for evidence-based practice and nursing scholarship. AIM: This study aimed to investigate the impact of incorporating action learning into undergraduate nursing research classes to improve the quality of nurse education. DESIGN: A mixed-methods approach was employed using pre- and post-online surveys for quantitative analysis and reflective journals for qualitative analysis. SETTINGS: The study was conducted at a college of nursing in Seoul, South Korea. PARTICIPANTS: A convenience sample of 19 fourth-year nursing students participated in the study. METHODS: Action learning-based nursing research classes were implemented over ten sessions, integrating lectures and team activities. Pre- and post-assessment data on communication skills, critical thinking tendencies, and problem-solving abilities were analyzed using paired t-tests. The qualitative analysis involved content analysis of individual and team reflective journals. RESULTS: Participants in action learning-based nursing research classes showed significant improvements in their communication skills (t = 3.46, p = 0.002), critical thinking tendencies (t = 3.80, p = 0.001), and problem-solving abilities (t = 1.82, p = 0.043). From the analysis of reflective journals four main themes were developed: organized team projects, dynamics of learning goal achievement, extended application of learning outcomes, and recommendations for better action learning-based classes. CONCLUSIONS: This study highlights action learning as an effective educational method that integrates theory and practice in nurse education, helping students prepare for their future roles as nursing professionals. The findings underscore the effectiveness of action learning in improving undergraduate nursing students' research competency and support the need for continued development of such pedagogical approaches.
