Coordinated control of single-point moored floating multi-wind turbines under fault events and shutdowns

Abstract The emergence of novel concepts aimed at the reduction of floating offshore wind energy cost is increasingly demanding new control approaches. This is the case of floating offshore multi-wind turbine assets (FOMWT), with two or more full wind turbines placed on the same floating platform. The strong dynamic interaction among the sub-components of such systems requires appropriate coordination of the commands driven by the individual wind turbine controllers. The impact of such coupling may increase depending on the asset confguration, as is the case of single-point distribution of mooring lines, commonly applied to FOMWTs. Among the most demanding situations are those under fault events and shutdowns, which may cause large uncontrolled platform rotation and put the system integrity at risk. To address this, a new coordinated control level, mastering the individual turbine controllers hierarchically, is proposed to govern the whole asset. The control concept proves to be effective under a reduced set of extreme load cases in accordance with standards for a two-wind turbine FOMWT. The simulations are performed with the multi-wind turbine simulation tool MUST, which accounts not only for the interaction among the two turbines and the platform, but also for the communication of the coordinated control and the individual turbine control levels.

The Scientific And Technological Research Capacity Of The Vietnamese Trade Union And Some Issues Raised

In the context of globalization and the rapid development of science and technology (S&T), enhancing S&T research capacity has become a crucial factor for organizations, including the Vietnamese Trade Union. The role of the Trade Union is not only limited to protecting workers' rights but also requires active participation in research and application of S&T to help improve working conditions, increase production efficiency, and enhance the lives of workers. However, the S&T research capacity of Trade Union organizations in Vietnam still faces many limitations and has yet to meet the development needs and demands of practical situations. This article assesses the current state of S&T research capacity of the Vietnamese Trade Union, identifies existing issues, and proposes solutions to improve research quality, contributing to promoting activities to protect workers' rights in the new context

Roles of Psychological Flexibility, Parenting Competence, and Asthma Management Self-Efficacy in the Functioning Outcomes of Parents of Children with Asthma Co-Occurring with Attention-Deficit/Hyperactivity Disorder

Asthma and ADHD represent prevalent pediatric conditions, with the former being a physical disorder and the latter being a neurodevelopmental disorder. This study examined the influence of parental psychological flexibility (PF)—the ability to adapt to evolving situational demands, shift perspectives, and balance competing priorities—alongside parenting competence and asthma management self-efficacy on family functioning and parental psychological adjustment in families with children exhibiting concurrent asthma and ADHD symptoms. Baseline data were analyzed from 130 parents (mean age = 40.3 years, SD = 5.5; 88.9% mothers) of children diagnosed with both asthma and ADHD (mean age = 8.0 years, SD = 2.2; 74.6% boys), who were participating in a randomized controlled trial evaluating an Acceptance and Commitment Therapy (ACT)-based parenting intervention. An adjusted structural equation model revealed that greater parental psychological inflexibility was significantly associated with poorer family functioning (β = −0.61, 95% CI [−0.74, −0.33], p < 0.001) and increased psychological maladjustment (β = 0.48, 95% CI [0.32, 0.63], p < 0.001), accounting for intercorrelations with parenting competence and parental asthma management self-efficacy. Additionally, parental psychological flexibility was found to mediate the relationship between parenting competence and both family functioning and psychological adjustment. These findings underscore the importance of targeting parental psychological inflexibility and enhancing parenting competence in interventions to improve family dynamics and parental mental health and thereby suggest a shift from the traditional focus on self-efficacy in symptom management for pediatric asthma and ADHD.

Emotion regulation use in daily-life and its association with success of emotion-regulation, self-efficacy, stress, and state rumination.

Investigations on emotion regulation strategies (ERS) primarily focus on the influence of instructed emotion regulation (ER) on outcomes. However, recent work has shown that selection of ERS is dependent on, e.g., situational demands and personal resources. In this current investigation, we used an online diary to investigate ERS used by free choice and their association with ER-success, stress and rumination. We identified four factors of ERS: cognitive perspective change, cognitive-behavioral problem-solving, suppression-distraction and body-social ERS. Associations of ERS with stress, state-rumination and ER-success were investigated using multilevel-mixed-models, allowing to separate within- and between-subject effects. Our results show that, on a within-subject level, all adaptive ERS were positively associated with ER-success, while maladaptive ERS as well as higher stress and state rumination were negatively associated with ER-success. On the other hand, only within-subject cognitive ERS were associated with higher self-efficacy. Maladaptive ERS-use was consequently positively associated with stress and state rumination. Surprisingly, only cognitive perspective change ERS were negatively associated with state rumination. Cognitive-behavioral problem-solving was positively associated with stress and success of emotion regulation. We interpret these results in the light of situational constraints of ERS-use and the importance of the assessment of these in future studies.

Daily manifestations of psychopathology in response to stress.

Psychological functioning is shaped by how people navigate their environment. Accordingly, psychopathology is often caused and maintained by patterns of responding to the environment that do not meet situational demands. In particular, psychopathology is often expressed in an inflexible or intense manner of coping with stressful situations. Prior research on psychopathology and daily life stress is limited by an overreliance on negative affect reactivity, which neglects the myriad responses that can create problems in a person's life. In this study, we assessed a broad range of daily manifestations of psychopathology to examine daily psychopathology-stress associations. We conceptualized individual differences in functioning as psychopathology traits and daily fluctuations in the interrelated thoughts, behaviors, and emotions as psychopathology states, with traits and states corresponding to the same domains of functioning (i.e., antagonism, detachment, disinhibition, negative affectivity, anankastia, psychoticism). Data have been taken from two samples enriched for psychopathology (N = 112, N = 294 participants) who completed daily assessments of stressors and psychopathological states (n = 9,201, n = 4,292 days). We used multilevel structural equation models to examine average, within-person associations between stressors and psychopathological states and correlations between psychopathological traits and stress responses. Results showed that (a) most people experience increases in psychopathological states when stressed and (b) psychopathological traits relate to more consistent and stronger increases in psychopathological states. Our study suggests that psychopathology reflects how people cope with stressful situations, and what distinguishes people with high-trait psychopathology from those who experience typical upticks in psychopathology when stressed is the consistency and extremity of their responses.

A systematic review of individual, social, and societal resilience factors in response to societal challenges and crises

Societal challenges put public mental health at risk and result in a growing interest in resilience as trajectories of good mental health during stressor exposure. Resilience factors represent multilevel psychosocial resources that increase the likelihood of resilient responses. This preregistered systematic review aims at summarizing evidence on the predictive value of individual, social and societal resilience factors for resilient responses to societal challenges and crises. Eligible studies examined the predictive value of resilience factors in stressor-exposed populations in high-income countries by means of multinomial regression models based on growth mixture modeling. Five databases were searched until August 2, 2023. Data synthesis employed a rating scheme to assess the incremental predictive value of resilience factors beyond sociodemographic variables and other resilience factors. An adapted version of the Newcastle-Ottawa Scale was used for risk of bias assessment. Fifty studies (sample sizes: 360–65,818 participants) with moderate study quality reported on various stressors (e.g., pandemics, natural disasters, terrorist attacks). Higher income, socioeconomic status and perceived social support, better emotion regulation and psychological flexibility were related to more resilient responses. The association between resilience factors and resilient responses was stronger in samples with younger mean age and a larger proportion of women. Most studies used non-representative convenience samples and effects were smaller when accounting for sociodemographic variables and other resilience factors. For many factors, findings were mixed, supporting the importance of the fit between resilience factors and situational demands. Research into social and societal resilience factors and multilevel resilience interventions is needed. Preregistration-ID: 10.17605/OSF.IO/GWJVA.

Exploring the Effects of Coping Flexibility on Sleep Quality via Subjective Distress: A Longitudinal Study of Young Adults.

Coping flexibility is one's ability to modify their coping strategies and adapt to the demands of stressful situations. However, limited studies have demonstrated that coping flexibility directly influenced sleep quality. This study examined the relationships between coping flexibility, subjective distress, and sleep quality. We hypothesized that coping flexibility would enhance sleep quality via subjective distress. In total 99 male and 151 female college students completed questionnaires on coping flexibility, subjective distress, and sleep quality. Subsequently, they completed the questionnaire on sleep quality six months later. Structural equation modeling showed a significant indirect effect of coping flexibility, which indicated that higher coping flexibility was associated with higher sleep quality via reduced subjective distress. Our findings suggested that subjective distress and lower coping flexibility were risk factors for poor sleep quality.

6G in medical robotics: development of network allocation strategies for a telerobotic examination system.

Healthcare systems around the world are increasingly facing severe challenges due to problems such as staff shortage, changing demographics and the reliance on an often strongly human-dependent environment. One approach aiming to address these issues is the development of new telemedicine applications. The currently researched network standard 6G promises to deliver many new features which could be beneficial to leverage the full potential of emerging telemedical solutions and overcome the limitations of current network standards. We developed a telerobotic examination system with a distributed robot control infrastructure to investigate the benefits and challenges of distributed computing scenarios, such as fog computing, in medical applications. We investigate different software configurations for which we characterize the network traffic and computational loads and subsequently establish network allocation strategies for different types of modular application functions (MAFs). The results indicate a high variability in the usage profiles of these MAFs, both in terms of computational load and networking behavior, which in turn allows the development of allocation strategies for different types of MAFs according to their requirements. Furthermore, the results provide a strong basis for further exploration of distributed computing scenarios in medical robotics. This work lays the foundation for the development of medical robotic applications using 6G network architectures and distributed computing scenarios, such as fog computing. In the future, we plan to investigate the capability to dynamically shift MAFs within the network based on current situational demand, which could help to further optimize the performance of network-based medical applications and play a role in addressing the increasingly critical challenges in healthcare.

Moving Engagement Theory Forward: My Practical Insights on Activation's Centrality to Understanding Gender Differences in Discretionary Workplace Commitment

This article explores the concept of activation as a missing theoretical link for understanding gender differences in discretionary workplace commitment. Activation refers to an individual's readiness to take action and has been shown to influence engagement outcomes through its impact on effort and attention levels. The article first reviews key academic literature establishing engagement theory and the role of activation. It then shares real-world examples where activation helps explain observed gender differences in discretionary behaviors beyond basic job duties. Differences in situational job demands and available resources that differentially impact women's activation reserves are also examined. The article argues that conceptualizing engagement through an activation lens can help address why discrepancies occur and suggest impactful job redesign strategies. Recommendations focus on boosting activation for all employees through initiatives like flexible scheduling, social support programs, and inclusive cultures. The discussion proposes advancing engagement theory by considering the understudied yet important role of activation, particularly regarding gender.

Metajudgment: Metatheories and Beliefs About Good Judgment Across Societies.

We introduce the concept of "metajudgment" to provide a framework for understanding folk standards people use to navigate everyday decisions. Defined as a set of metatheories and beliefs about different types of judgment, metajudgment serves as the guiding principle behind the selection and application of reasoning strategies in various contexts. We review emerging studies on metajudgment to identify common dimensions, such as intuition versus deliberative reasoning and rationality versus reasonableness. These dimensions are examined across multiple societies. The reviewed findings illuminate an apparent paradox: Universal adaptive challenges produce largely consistent folk standards of judgment across cultures, whereas situational demands drive systematic within-person variability. Metajudgment offers a comprehensive framework for understanding diverse reasoning patterns in individual and cross-cultural contexts, calling for greater attention to the ecologically sensitive study of within-person judgmental variability.

Impact of state and trait emotion regulation on daily emotional exhaustion among Korean school counsellors.

School counsellors in South Korea face significant emotional exhaustion due to their challenging occupational environment. Previous studies have shown that cognitive reappraisal (CR) reduces emotional exhaustion, whereas expressive suppression (ES) increases it. However, these findings predominantly rely on trait questionnaires within cross-sectional approaches, overlooking the dynamic nature of emotion regulation (ER) strategy selection. Individuals may choose strategies that deviate from their general tendencies based on situational demands. There is limited empirical knowledge regarding the interaction between trait and state regulation strategies and their influence on exhaustion. Utilizing the strategy-situation fit hypothesis, this study examines the context-specific effects of ER strategies, considering both situational contexts and individual response tendencies. A multilevel analysis was performed to examine the influence of state and trait ER strategies on daily emotional exhaustion. A daily diary study was conducted for 5days with 111 Korean school counsellors. Daily CR was associated with lower daily exhaustion and daily ES predicted higher daily exhaustion. Contrastingly, none of the trait ER strategies had an impact on daily exhaustion, but the trait level of both strategies significantly moderated the relationship between daily CR and exhaustion. The positive impact of daily CR was more pronounced in school counsellors who often utilized suppression strategies, and this impact was also evident in trait reappraisal. Re-evaluating daily emotions instead of suppressing them may assist in coping with emotional exhaustion caused by work. The effectiveness of these strategies may vary based on an individual's inclination to regulate emotions as state and trait. ER may aid in implementing preventive interventions for school counsellors experiencing emotional exhaustion.

Using a digital data analytic tool to capture dynamic change in coordination patterns: An exploratory study of the Apollo 13 mission

The operational environment of complex sociotechnical systems is inherently uncertain, demanding constant coordination restructuring to adapt to dynamic situational demands. However, coordination changes in the Human Factors and Ergonomics Field have primarily been studied using static methods, overlooking moment-by-moment adjustments. In the current study, we address coordination restructuring by using THEME, a digital analytical tool capable of visualising and exploring coordination restructuring from a multi-layered perspective. We examine restructuring in coordination patterns during NASA's Apollo 13 Mission, revealing significant shifts from stable, long-duration ‘coordination hubs' in routine operations to shorter-duration patterns during a crisis situation. Additionally, the results highlight the importance of flexible switching between reciprocal and one-directed coordination, along with enhanced role distribution. This study underscores how exploring temporality-sensitive phenomena like coordination through digital technologies such as THEME, advances our understanding of incident analysis and resilient performance within complex systems.

Emotion regulation flexibility: EEG/EMG predictors and consequences of switching between reappraisal and distraction strategies.

Flexible use of emotion regulation (ER) strategies is central to mental health. To advance our understanding of what drives adaptive strategy-switching decisions, in this preregistered study, we used event-related potentials (late positive potential, LPP and stimulus preceding negativity, SPN) and facial electromyography (EMG corrugator activity) to test the antecedents and consequences of switching to an alternative ER strategy. Participants (N = 63, Mage = 24.8 years, all female) passively watched and then implemented an instructed ER strategy (reappraisal or distraction) in response to high-intensity negative pictures that were either easy or difficult to reinterpret (high or low reappraisal affordance, respectively). Next, they decided to "switch from" or "maintain" the instructed strategy and subsequently implemented the chosen strategy. Reappraisal affordance manipulations successfully induced switching. Regarding antecedents, switching was predicted by the reduced ER efficacy of the current strategy (corrugator, but not LPP). Switching to distraction was additionally predicted by increased responses to the stimulus during passive viewing (corrugator and LPP) and increased anticipatory effort in implementing reappraisal (SPN). Concerning consequences, switching to distraction improved, whereas switching to reappraisal impaired post-choice ER effects (LPP). However, starting with reappraisal was overall more effective than starting with distraction, irrespective of the subsequent decision (corrugator). Our results suggest that switching between ER strategies occurs in accordance with situational demands (stimulus affordances) and is predicted by reduced peripheral physiological ER efficacy. However, only switching to distraction leads to improved regulatory effects. These insights provide neurocognitively grounded starting points for developing interventions targeting ER flexibility.

Intimacy and sexual functioning after cancer: The intersection with psychological flexibility

Cancer significantly impacts overall satisfaction with life (SWL). Psychological flexibility (PF) involves adapting to situational demands, balancing life demands, and committing to value-aligned behaviours, which can help survivors manage cancer-related distress. Given the lack of research examining how PF affects relationship and sexual satisfaction, our purpose was to elucidate the relationship between variables associated with partner intimacy, pillars of PF, and variables related to psychological wellness. We explored relationships between SWL and the pillars of PF (Valued Action, Behavioural Awareness, Openness to Experience) as mediating factors in the association between relationship and sexual satisfaction and SWL. Participants (113 male, 106 female) completed questionnaires measuring sexual function, intimacy, relationship and sexual satisfaction, PF, SWL, anxiety, and depression. Results indicated an equal percentage (57.5%) of males and females reported sexual dysfunction; however, varied patterns of relationships emerged between the sexes. There were significant relationships between SWL and relationship and sexual satisfaction. The mediation analyses showed that valued action and openness to experience partially mediated the relationship between relationship satisfaction and SWL. Interestingly, Valued Action was the only pillar of PF that emerged as a partial mediator between sexual satisfaction and SWL. Thus, value-aligned behaviours may be a key focus for intervention in cancer survivors.

Comparative studies of different solutes effects on microstructure and comprehensive performance of coherent precipitation-strengthened Cu–Ni–Al alloys

Multi-componentization can further improve the heating resistance of Cu–Ni–Al alloys, enabling them to withstand more demanding situations. Unfortunately, the limited researches have been done on the wear and corrosion resistance of the heat-resistant Cu–Ni–Al alloys, resulting in the lack of relevant evidence in the practical application. In this work, a comparative study of differential types of trace element, Si (the stronger enthalpy interaction element), Sn (the weaker enthalpy interaction element) Cr or Zr (grain boundary strengthening element), effects on microstructure, wear and corrosion resistance will be done, Furthermore, the effect of different trace elements on the surface electron work function and electrochemical behavior of Cu–Ni–Al alloys is reflected by SPM surface potential model. The results indicate that the precipitation of dual nano-phase and accelerated precipitation of γ′ phase can be realized through the addition of Si, Sn, Cr and Zr, in which the value of δγ-γ′ increase sharply after adding Si and it is not conducive to the preservation of cuboidal γ′ phase. The addition of Si, Cr and Zr can improve electron work function distribution and mechanical property, wear, and corrosion resistance of the alloys, in which Si is more conducive to the improvement of wear resistance and mechanical properties of the alloy, while the alloy with Cr and Zr shows the excellent corrosion resistance. The addition of Sn will weaken the enthalpy interaction of the alloy system, reduce the electron work function of the alloy, and have adverse effects on the wear and corrosion resistance of the alloy.

Elite athletes’ values in action: an important yet complicated aspect in anti-doping education

ABSTRACT Values-based education seeks to cultivate personal responsibility, empathy, and integrity to encourage critical reflection on the (anticipated or actual) consequences of one’s choices and behaviours. To comply with the World Anti-Doping Agency's International Standard for Education, anti-doping education programmes must incorporate values-based components. To facilitate this development, we explored how elite athletes interpret and apply their values in various situations throughout their athletic careers. Adopting a qualitative description design, 13 focus groups were conducted with 60 elite athletes from 13 countries participating in 27 sports at national or international levels. Audio recordings were transcribed/translated and analysed using reflexive thematic analysis. Athletes noted that their values guide their actions but struggled to articulate how these values influence their behaviour. Three overarching themes were created to capture: (1) value consciousness and clarity, (2) intrapersonal value continuity, and (3) value conflict and management. Dynamic relationships between athletes’ values, priorities, and decision-making processes were evident. Specifically, the results illustrate shifts in value priorities as athletes matured and progressed in their careers, and across situations to meet situational demands whilst making behaviour personally permissible. To live up to the fundamental principles of values-based education, anti-doping programmes must incorporate activities that facilitate conceptually sound discussions and provide athletes with time and support to unpack the behavioural meaning of their values. Developing athletes’ decision-making abilities through conscious sense-making activities to anticipate the pain of a value transgression and the value of value fulfilment is key to this process.

A cognitive task analysis of final year nursing students' situation awareness in simulated deteriorating patient events: A mixed methods study.

The aim of this study was to: (1) use cognitive task analysis to describe final year nursing students situation awareness in recognising, responding and escalating care of deteriorating patients in ward settings; and (2) make recommendations for training and practice. A mixed methods cognitive task analysis with a convergent triangulation design. Data collection involved observations of 33 final year nursing students in simulated deteriorating patient scenarios and retrospective cognitive interviews. A process tracing technique was applied to identify the cues to deterioration participants perceived; how cue perception altered as situational demands increased; the extent that participants made connections between perceived cues and reached a situational understanding; and the factors that influenced and constrained participants situation awareness. Qualitative and quantitative findings are woven together and presented using descriptive statistics, illustrative quotations and timeline extractions. The median cue perception was 65.4% and 57.6% in the medical and surgical scenarios, respectively. Perception was negatively influenced by incomplete vital sign monitoring as situations escalated; limited physical assessments; passive scanning behaviours; poor task automaticity; and excessive cognitive demands. Incomplete perception, poor cue integration and underdeveloped mental models influenced situational understanding. Escalation calls did not always accurately reflect situations and a reporting mindset was evident. Clinical exposure to deteriorating patients was described as variable and opportunistic. The study is reported in accordance with the Good Reporting of a Mixed Methods Study (GRAMMS) checklist. Patients and public were not involved in this research.

Spatial and Temporal Analysis: A GIS-Based Application Tool for Crime Monitoring and Clustering in Malawi

For the purposes of monitoring, evaluating, and conducting a geographical analysis of crime-related data, the study used geospatial technology to collect crime data based on spatial location and the Malawi Police Data Digest of 2019 and 2020. In a more generic sense, knowing the geographic patterns of crime in Malawi using GIS technology can help determine how to make and implement important decisions to reduce crimes in Malawi. The Malawi Police Service has established a number of database management systems to help with crime monitoring. Notwithstanding, it has not yet fully integrated Geographic Information Systems across all jurisdictions. Maps showing crime locations and crime hotspot zones are therefore not included in the crime data and statistics report provided by the Malawi Police Service. In this light, a lot of people have become victims of various forms of crimes in areas where those crimes are also prevalent. To collect, track, and analyze crime data in Malawi for this study, Geographical Information System (GIS) particularly network analysis techniques were used. Network Analysis was used to identify crime hotspots by analyzing crime data as a network of interconnected events and locations. The rationale behind this was to treat each crime event as a node in the network and the spatial relationships between the crimes as edges. By analyzing this network, patterns and relationships between crime events were revealed, allowing for the identification of crime hotspots. The study found that Lilongwe in the central region and the capital city registered the highest number of crimes seconded by Blantyre in the southern region and followed by Mangochi. Mzimba recorded high crimes in the northern region. In Malawi, the traditional systems of intelligence and criminal record keeping have failed to satisfy the demands of today's crime situation. Manual methods neither give accurate, dependable, or complete data 24 hours a day nor do they help in trend forecasting and decision assistance. It also leads to poorer productivity and inefficient workforce use. The appropriate application of information technology is the solution to this ever-increasing challenge.

Mindfulness and Resilience: Studies about Millennials duringCOVID-19 Why do some people seem so resilient?

Maintaining self-control in a complex environment and adjusting to shifting situational demands require resilience. Many studies have investigated how mindfulness practices affect millennials’ psychological well-being (PWB) and adversity resilience. The paper talks about studies related to millennials. Finally, the paper concluded that considering the relationship between resilience and physical health adds another dimension to this framework, emphasizing the importance of holistic approaches in promoting well-being.

Media Multitasking in Younger and Older Adults: Associations with Cognitive Abilities and Biological Stress Responses

ABSTRACT Media multitasking is increasingly common in everyday life and can be a stressful experience, especially for older adults. The current study investigated the effects of media multi- vs. single-tasking on both task performance and biological as well as subjective stress responses in an experimental laboratory setting based on a scenario that closely replicated the demands of a multitasking situation, in which a strenuous and repetitive primary task was interrupted by relevant messages that require attention. We examined differences in media multitasking performance and associated stress between younger (18–35 years) and older (65–85 years) adults, and differences in cognitive abilities as a potential explanation for expected age-related differences in media multitasking. The findings suggested lower task performance in the multitasking condition in both age groups. The older adults showed even higher multitasking costs, but we found no evidence of lower cognitive abilities as an explanation of this effect. Media multitasking was not found to elicit greater stress responses (biological or subjective) than single-tasking. However, the results indicate that older adults have a greater biological stress response (salivary α-amylase) than younger adults when working on a computer under time pressure, regardless the task requirements (single- or multitasking).
