Dual Systems Imbalance as a Mediator of the Relationship Between Exposure to Violence and Violent Offending Risk: Delineating Direct Victimization and Witnessed Violence.

Exposure to violence is a robust risk factor associated with violent offending. Furthermore, exposure to violence can lead to dysfunctional cognitive development, and this may underpin the relationship between exposure to violence and violent offending risk. However, there is a dearth of research that has examined the independent effects of direct victimization and witnessed violence in this regard, particularly as it pertains to dual systems imbalance as a cognitive mediator of either or both forms of exposure to violence. This study sought to address this gap in the literature by examining the effects of direct victimization and witnessed violence on violent offending risk and examining dual systems imbalance as a mediator of these relationships. The Pathways to Desistance data were analyzed. Generalized structural equation modeling was used to assess the direct and indirect effects of interest. The results indicated that only experiencing direct victimization was associated with an increased risk of violent offending at follow-up but not witnessed violence. Furthermore, dual systems imbalance significantly mediated the relationship between direct victimization and violent offending risk. The results indicate that justice-involved youth who have experienced direct victimization should be prioritized for intervention in order to reduce violent recidivism risk and that treatment should focus on improving cognitive processes pertaining to impulse control and risk-seeking.

Exploring perceptual grouping by proximity principle in multistable dot lattices: Dissociation between vision-for-perception and vision-for-action.

Perceptual grouping, a fundamental mechanism in our visual system, significantly influences our interpretation of and interaction with the surrounding world. This study explores the impact of the proximity principle from the perspective of the Two Visual Systems (TVS) model. The TVS model argues that the visual system comprises two distinct streams: the ventral stream, which forms the neural basis for "vision-for-perception," and the dorsal stream, which underlies "vision-for-action." We designed a perceptual grouping task using dot lattices as well as a line-orientation discrimination task. Data were collected using vocal and mouse methods for the vision-for-perception mode, and joystick and pen-paper methods for the vision-for-action mode. Each method, except for vocal, included separate blocks for right and left hands. The proximity data were fitted using exponential and power models. Linear mixed-effects models were used for the statistical analyses. The results revealed similar line-orientation discrimination accuracy across all conditions. The exponential model emerged as the best fit, demonstrating adherence to the Pure Distance Law in both perceptual modes. Sensitivity to the proximity principle was higher in the vision-for-action mode compared to the vision-for-perception. In terms of orientation biases, a strong preference for vertical orientation was observed in the vision-for-perception mode, whereas a noticeable preference toward either of the oblique orientations was detected in the vision-for-action mode. Analysis of free-drawn lines demonstrated an affordance bias in the vision-for-action mode. This suggests a remarkable tendency to perceive organizations within specific orientations that offer more affordances due to the interaction between the body postures and tools.

Characterization of the information system integrated to the construction project management systems.

The construction industry wields significant influence in the economies of various countries. However, compared to sectors like manufacturing and aeronautics, it has lagged in terms of digitalization of processes and project management advancement. This study aims to explore how the integration of Lean principles, Building Information Modeling (BIM), and Project Lifecycle Management methodologies within an information system can enhance decision-making in construction project management as a complex environment. A comprehensive literature review was conducted to establish a conceptual framework and gather necessary information for designing an information system. The design was based on the viable systems model and the soft systems methodology, from a systemic perspective that encourages the synergistic interaction of these methodologies. The resulting abstract model would facilitate a comprehensive understanding of the interconnectedness of these methodologies, emphasizing collaborative work environments for efficient information management. This approach aims to replace the current isolated application of each of those methodologies and promises improved project management performance.

Improving Transitions in Care for the Child with Medical Complexity Using Betty Neuman's Systems Model.

Children with medical complexity are an increasing population with frequent use of intensive care services within hospitals. As children's health improves, they are often transferred to a general unit before being discharged to home. This transition often leads to an acute decline in health, resulting in emergent interventions. Betty Neuman's systems model provides the foundation to guide prevention interventions on stress mitigation to promote stability. An evidence-based transition bundle of care may be a valuable tool to prevent stress at the time of transfer from the intensive care unit and prevent deterioration.

Truth for the Moment and Importance to Nursing.

In the article that follows the authors present information focused on nursing care delivery involving Neuman systems theory and improving the stress and stability. The authors then follow up with a clinical scenario which utilizes the Neuman system model as a means to prevent and ameliorate aggression and violence. The structure and evidence guided by Betty Neuman's systems model centers on managing and reducing stresses and working towards reconstitution. The thoughts contained in this article highlight some considerations regarding the importance of truth and truth for the moment for the nursing discipline.

The Effect of the Neuman Systems Model-Based Training and Follow-up on Self-Efficacy and Symptom Control in Patients Undergoing Chemotherapy.

In this article, the authors aimed to determine the effect of the training and follow-up based on the Neuman systems model provided to patients undergoing chemotherapy on their self-efficacy and symptom control. The study was carried out with a randomized controlled experimental study model design. The sample consisted of 102 patients including 52 in the experimental group and 50 in the control group. The data were collected using the Patient Information Form, the Cancer Behavior Inventory-Brief (CBI-B), and the Edmonton Symptom Assessment Scale (ESAS). A personal training program prepared according to the Neuman systems model was applied to the experimental group patients. In the intergroup comparison of the experimental and control group patients, there was an increase in the posttest CBI-B scores and a decrease in the ESAS scores in the experimental group compared to the control group, and the intergroup difference was statistically significant (p < .05). According to the results, to improve the self-efficacy and symptom control in patients undergoing chemotherapy, using this education and follow-up program is recommended.

The Neuman Systems Model: A Framework for Aggression and Violence Prevention.

Aggression and violence influence nurse-client relationships and the quality of care provided, and just as important, they also influence the nurses' physical and emotional well-being. The Neuman systems model is utilized to define and understand factors that contribute to aggressive and violent behavior and for the purposes of providing a systematic approach to the prevention and management of stressors leading to aggression and violence.

Major Depressive Disorder as a Driver of Dual Systems Model Development During Adolescence and Emerging Adulthood Among Justice-Involved Youth: Is Salience Age-Graded?

The dual systems model is a psychological framework centered on differential development of sensation-seeking and impulse control during adolescence and emerging adulthood with implications for understanding antisocial behavior. However, there is a dearth of research which has examined mental illness as a driver of differential development of these constructs. This study examined major depressive disorder as a risk factor for elevated sensation-seeking and diminished impulse control and tested to determine whether the salience differed by age. The Pathways to Desistance data were analyzed. Mixed effects models examined the direct effect of major depressive disorder on dual systems outcomes and test for moderation by age. Findings indicated that major depressive disorder at baseline was associated with increased sensation-seeking and diminished impulse control. Relationships did not differ in salience based on age. Results suggest that treatment effective for addressing depression may have relevance for mitigating the impact of the disorder on cognition.

Cognitive dissonance and mindset perturbations during crisis: "eco-socio-psycho-somatic" perspectives.

Mandatory and restrictive health regulations during the corona pandemic caused psychic disorders in many people, which even led to clinically relevant mental disorders. At the same time, there was gradually a polarization of opinions among the population. In order to improve future pandemic management, an integrative understanding of these psychosocial processes therefore seems useful. Here we start theoretically with the mental effects of inconsistencies of the information environment by referring to concepts such as the theory of cognitive dissonance. In a next step, we use the psychodynamic theory to understand the affective-motivational defense mechanisms underlying these cognitive states and processes. However, a broader theoretical framework of psychoanalysis seems to make sense, because self-referential processing also influences the style of thinking. For this reason, we use a more comprehensive psychological systems theoretical framework model to integrate these different perspectives. This integrative view refers in part to basic knowledge of health psychology regarding the resistance of unhealthy ways of thinking and behaviors and the possibilities for interventions for change. We then extend this model to a broader picture that also covers the relationship between men and their environment. This results in the perspective of a multidimensional socioecological theoretical framework, which as a heuristic reference model and related to other ecological approaches could also be helpful for various theoretical questions for public health, and could provide a better public understanding of health issues. In line with this perspective, we hypothesize that with regard to the coronavirus disease 2019 pandemic, the acceptance of public health narratives could be increased if a more consistent picture of the scientific descriptions and explanations of the pandemic - similar to the model proposed - could be provided, which would enable the understanding of the origin, course and countermeasures, and thus could have positive collective psycho-hygienic effects.

'You have a lot of mirrors': structural and socioecological factors impacting adolescent pregnancy and reproductive health in the Amazon basin, Peru, a qualitative study.

Loreto, in the Peruvian Amazon, has one of the highest adolescent pregnancy rates in the country. However, underlying causes of adolescent pregnancy are not fully understood as data are limited in Indigenous and remote Amazonian communities. This study investigated adolescent reproductive health within Loreto using an ecological systems framework. Forty-one semi-structured interviews were conducted in June 2022: community leaders (n = 12) and adolescent participants between 15 and 17 years of age (pregnant girls, n = 11; never pregnant girls, n = 9; and boys, n = 9). We also conducted focus group discussions with community health workers and educators in October 2022 (three focus groups, n = 15). Adolescent reproductive health is complex with multi-layered factors that put girls at higher risk of pregnancy. We found a paradoxical relationship between expected social and gender norms and individual desires. This research provides a contextual understanding of the lived experience of adolescents and young people in the Amazon region of Peru. Our findings suggest the need for greater exploration of the contradictory ideas surrounding adolescent pregnancy and female sexuality.

Development of the triadic neural systems involved in risky decision-making during childhood.

Risk-taking often occurs in childhood as a compex outcome influenced by individual, family, and social factors. The ability to govern risky decision-making in a balanced manner is a hallmark of the integrity of cognitive and affective development from childhood to adulthood. The Triadic Neural Systems Model posits that the nuanced coordination of motivational approach, avoidance and prefrontal control systems is crucial to regulate adaptive risk-taking and related behaviors. Although widely studied in adolescence and adulthood, how these systems develop in childhood remains elusive. Here, we show heterogenous age-related differences in the triadic neural systems involved in risky decision-making in 218 school-age children relative to 80 young adults. Children were generally less reward-seeking and less risk-taking than adults, and exhibited gradual increases in risk-taking behaviors from 6 to 12 years-old, which are associated with age-related differences in brain activation patterns underlying reward and risk processing. In comparison to adults, children exhibited weaker activation in control-related prefrontal systems, but stronger activation in reward-related striatal systems. Network analyses revealed that children showed greater reward-related functional connectivity within and between the triadic systems. Our findings support an immature and unbalanced developmental view of the core neurocognitive systems involved in risky decision-making and related behaviors in middle to late childhood.

The Dual Systems Model-Impulsivity and Narcissism as the Reflexive System and Self-Regulation as the Reflective System-of Smartphone Addiction.

The exploration of underlying mechanisms leading to the development of smartphone addiction has been limited, with only a few studies incorporating theories to provide explanations. Drawing upon the Dual Systems Model, this study tested the hypothesis that the reflective system of self-regulation would mediate the relation between the reflexive system of impulsivity and narcissism, and smartphone addiction in a sample of 298 undergraduate students. Participants completed a self-administrated web-based questionnaire containing measures of impulsivity (the Barratt Impulsiveness Scale), narcissism (the Narcissistic Personality Inventory), self-regulation (the Self-Regulation Scale), and smartphone addiction (the Smartphone Addiction Inventory). The findings from structural equation modeling revealed that self-regulation served as a significant mediator between impulsivity and smartphone addiction, as well as between narcissism and smartphone addiction. These findings offer insights that can contribute to the development of interventions and strategies that target impulsivity and narcissism by enhancing self-regulation skills.

Helping a Patient With a Pre-Existing Mental Health Condition Cope With Depression and COVID-19 Using the Neuman Systems Model: A Single Intrinsic Case Study.

Nursing theories and conceptual models shape nursing knowledge. This study applied the philosophical and theoretical basis of the Neuman Systems Model, which focuses on the use of primary, secondary, and tertiary nursing prevention for retention, attainment, and maintenance of patient system wellness, to a patient with pre-existing mental health conditions struggling to cope with depression and COVID-19 in a dedicated COVID-19 hospital in an urban area of Iran. The single intrinsic case study design used interviews, nursing observations, and document analysis to evaluate environmental factors and intra-, inter-, and extra-personal stressors. An advanced, outcome-oriented nursing care plan was developed.

Coming to grips with reality: Real grasps, but not pantomimed grasps, resist a simultaneous tilt illusion.

Investigations of grasping real, 3D objects subjected to illusory effects from a pictorial background often choose in-flight grasp aperture as the primary variable to test the hypothesis that the visuomotor system resists the illusion. Here we test an equally important feature of grasps that has received less attention: in-flight grasp orientation. The current study tested a variant of the simultaneous tilt illusion using a mirror-apparatus to manipulate the availability of haptic feedback. Participants performed grasps with haptic feedback (real grasps) and without it (pantomime grasps), reaching for the reflection of a real, 3D bar atop a background grating that induced a 1.1° bias in the perceived orientation of the bar in a separate sample of participants. Analysis of the hand's in-flight grasp orientation at early, late, and end stages of the reach showed that at no point were the real grasps biased by the illusion. In contrast, pantomimed grasps were affected by the illusion at the late and end stages of the reach. At each stage, the effect on the real grasps was significantly weaker than the effect of the illusion as measured by the mean point of subjective equality (PSE) in a two-alternative forced-choice task. In contrast, the effect on the pantomime grasps was statistically indistinguishable from the mean PSE at all three stages of the reach. These findings reinforce the idea that in-flight grasp orientation, like grasp aperture to pictorial illusions of target size, is refractory to pictorial backgrounds that bias perceived orientation.

OnGuard3e: A predictive, ecophysiology-ready tool for gas exchange and photosynthesis research.

Gas exchange across the stomatal pores of leaves is a focal point in studies of plant-environmental relations. Stomata regulate atmospheric exchange with the inner air spaces of the leaf. They open to allow CO2 entry for photosynthesis and close to minimize water loss. Models that focus on the phenomenology of stomatal conductance generally omit the mechanics of the guard cells that regulate the pore aperture. The OnGuard platform fills this gap and offers a truly mechanistic approach with which to analyse stomatal gas exchange, whole-plant carbon assimilation and water-use efficiency. Previously, OnGuard required specialist knowledge of membrane transport, signalling and metabolism. Here we introduce OnGuard3e, a software package accessible to ecophysiologists and membrane biologists alike. We provide a brief guide to its use and illustrate how the package can be applied to explore and analyse stomatal conductance, assimilation and water use efficiencies, addressing a range of experimental questions with truly predictive outputs.

A strategic action plan to enhance the accessibility of healthcare in rural areas of Zimbabwe.

OBJECTIVE: To identify strategies and develop a strategic action plan to enhance accessibility to healthcare in rural areas of Zimbabwe. METHODS: A cross sectional research approach with four (4) phases. Phase one (1) (quantitative), data was collected from professional nurses using self-administered questionnaires, healthcare users using interview questionnaires. Phase two (2) (qualitative), information was collected from a nominal group of national health directors leading to development strategic action plan in Phase three (3) informed by Phases 1 and 2, systems model and literature control. Strategic action plan was finalised and validated by members of the Parliamentary Portfolio Committee on Health in Phase 4. SETTINGS: Two districts (Masvingo and Chegutu) in two provinces (Masvingo and Mashonaland West) were involved. PARTICIPANTS: Conveniently sampled professional nurses (90) and healthcare users (445) using the sampled public health facilities (Phase 1); conveniently sampled national health coordinators (five) (Phase 2); and all five members of the Parliamentary Portfolio Committee on Health (Phase 4). RESEARCH FINDINGS: The strategic action plan focused on improving the health infrastructure; providing medical drugs, health workers and medical equipment; addressing shortages; and improving the capacity of the healthcare system. CONCLUSION: Active participation at all levels (professional nurses, healthcare users, national health directors and members of parliament) allowed the development of a strategic action plan.

The age-varying effects of adolescent stress on impulsivity and sensation seeking.

Adolescence is defined in part by heightened exposure and sensitivity to stressors. In a longitudinal cohort of youth at risk for substance use problems, we examined the age-varying relationship between stress exposure and traits that are central to the dual systems model. The positive associations between stress exposure, impulsivity, sensation seeking varied as function of age. Specifically, the influence of stress exposure on impulsivity strengthened during early adolescence and remained stable into early adulthood, while the influence of stress exposure on sensation seeking strengthened from early- to mid-adolescence and weakened thereafter. These findings suggest that the maturational imbalance between the capacity to regulate impulsive tendencies and sensation seeking may be exaggerated for youth who are exposed to a high number of stressors.

Identification and prediction of climate factors based on factor analysis and a grey prediction model in China.

Identifying and predicting the impacts of climate change are crucial for various purposes, such as maintaining biodiversity, agricultural production, ecological security, and environmental conservation in different regions. In this paper, we used the surface pressure (SP), surface temperature (ST), 2-m air temperature (AT), 2-m dewpoint temperature (DT), 10-m wind speed (WS), precipitation (PRE), relative humidity (RH), actual evapotranspiration (ETa), potential evapotranspiration (ETP), total solar radiation (TRs), net solar radiation (NRs), UV intensity (UVI), sunshine duration (SD), convective available potential energy (CAPE) as factors in our climate modeling. The spatiotemporal distribution characteristics of the climate factors were analyzed and identified based on historical data for China from 1950 to 2020 using factor analysis and a grey model (GM (1,1)), and their future change characteristics were predicted. The results show that there is a strong correlation between climate factors. ST, AT, DT, PRE, RH, and ETa are the main factors that have the potential to cause heavy rain, thunderstorms, and other severe weather. Meanwhile, PRE, RH, TRs, NRs, UVI, and SD are among the major factors linked to climate change. Specifically, SP, ST, AT, and WS are among the minor factors in most areas. The top ten provinces in terms of combined factor scores are Heilongjiang, Neimenggu, Qinghai, Beijing, Shandong, Xizang, Shanxi, Tianjin, Guangdong, and Henan. The trend of climate factors in China is expected to remain relatively stable over the next 30 years, with a noteworthy decrease observed in CAPE compared to the past 71 years. Our findings can help to better mitigate the risks associated with climate change and enhance resilience; they also provide a scientific basis for environmental, ecological, and agricultural systems to cope with climate change.

Impact of tetravalent dengue vaccination with screening, ADE, and altered infectivity on single-serotype dengue and Zika transmission.

Acquired immunity to a dengue virus serotype (whether by infection or the only licensed dengue vaccine) can produce antibody-dependent enhancement (ADE) in later infections with another dengue serotype, resulting in higher viral loads and more severe symptoms such as dengue hemorrhagic fever, unless the person already has immunity to multiple dengue serotypes. Screening to confirm dengue seropositivity is therefore recommended before vaccination. Recent studies suggest that the closely-related Zika virus may also interact with dengue through ADE. This study uses a mathematical model to evaluate the likely impact of imperfect screening and dengue vaccination on the spread of both viruses in a population where only one dengue serotype circulates, although the vaccine may take against any or all of the four recognized serotypes. Analysis focuses on the reproductive numbers of the viruses. Results indicate that vaccination increases the spread of Zika through induced ADE, while its impact on the spread of dengue depends on screening specificity and serotype-specific vaccine efficacies, as well as the intensity of ADE. Numerical analysis identifies the roles played by age-in and catch-up vaccination as well as screening characteristics and prior dengue exposure.

Pathogenesis of Necrotizing Enterocolitis in Preterm Infants: An Adaptation of Neuman's Systems Theory.

Preterm infants have increased morbidity and mortality due to immature physiology and neonatal complications. Necrotizing enterocolitis (NEC) is a devastating gastrointestinal complication that affects morbidity and mortality in preterm infants. The authors present an adaptation of Neuman's systems model called the NEC systems model to explore intrinsic and extrinsic factors leading to NEC in preterm infants. The literature was searched for theoretical models to guide exploration of neonatal disease influenced by the environment. Neuman's Systems Model provides a holistic approach to care of the system, offering a foundation to develop frameworks to examine preterm infants in their environment with associated stressors.
