Abstract. Resting respiratory sinus arrhythmia (RSA) is related to individual differences in waking affective style and self-regulation. However, little is known about the stability of RSA between sleep/wake stages or the relations between RSA during sleep and waking affective style. We examined resting RSA in 25 healthy undergraduates during the waking state and one night of sleep. Stability of cardiac variables across sleep/wake states was highly reliable within participants. As predicted, greater approach behavior and lower impulsivity were associated with higher RSA; these relations were evident in early night Non-REM (NREM) sleep, particularly in slow wave sleep (SWS). The current research extends previous findings by establishing stability of RSA within individuals between wake and sleep states, and by identifying SWS as an optimal period of measurement for relations between waking affective style and RSA.

The Stability

Natural ecological communities are diverse, complex, and often surprisingly stable, but the mechanisms underlying their stability remain a theoretical enigma. Interactions such as competition and predation presumably structure communities, yet theory predicts that complex communities are stable only when species growth rates are mostly limited by intraspecific self-regulation rather than by interactions with resources, competitors, and predators. Current theory, however, considers only the network topology of population-level interactions between species and ignores within-population differences, such as between juvenile and adult individuals. Here, using model simulations and analysis, I show that including commonly observed differences in vulnerability to predation and foraging efficiency between juvenile and adult individuals results in up to 10 times larger, more complex communities than observed in simulations without population stage structure. These diverse communities are stable or fluctuate with limited amplitude, although in the model only a single basal species is self-regulated, and the population-level interaction network is highly connected. Analysis of the species interaction matrix predicts the simulated communities to be unstable but for the interaction with the population-structure subsystem, which completely cancels out these instabilities through dynamic changes in population stage structure. Common differences between juveniles and adults and fluctuations in their relative abundance may hence have a decisive influence on the stability of complex natural communities and their vulnerability when environmental conditions change. To explain community persistence, it may not be sufficient to consider only the network of interactions between the constituting species.

The disciplines of physiology and ecology are united by the shared centrality of the concept of homeostasis: the stability of a complex system via internal mechanisms of self-regulation, resilient to external perturbation. In the past decade, these fields of study have been bridged by the discovery of the lung microbiome. The respiratory tract, long considered sterile, is in fact a dynamic ecosystem of microbiota, intimately associated with the host inflammatory response, altered in disease states. If the microbiome is a “newly discovered organ,” ecology is the language we use to explain how it establishes, maintains, and loses homeostasis. In this essay, we review recent insights into the feedback mechanisms by which the lung microbiome and the host response are regulated in health and dysregulated in acute and chronic lung disease. We propose three explanatory models supported by recent studies: the adapted island model of lung biogeography, nutritional homeostasis at the host-microbiome interface, and interkingdom signaling and the community stress response.

Fixed Beam

In this article, the vibration attenuation of a fixed-fixed beam with a piezo-shape memory alloy ferrule is theoretically investigated. First, a dynamic model of the beam with a piezo-shape memory alloy ferrule is established, and the nonlinear dynamic response of the model is numerically analysed. The results show that the stability of the beam structure can be improved adaptively through self-regulation of the stiffness of the piezo-shape memory alloy ferrule undergoing external excitations. The effects of some internal system characteristics, such as the ferrule dimensions as well as the initial ferrule temperatures and boundary conditions, on the vibration attenuation of the beam are discussed. The stability of the proposed model under different external factors, including damping and external excitations, is also investigated. Compared with an aluminium ferrule, the present ferrule is better at the suppressing vibrations of the beam, and its adaptive property avoids the structural resonances for bigger ferrule sizes, making it more intelligent, efficient and convenient.

The Stability

The density of stands remains a controversial issue to this day, requiring a practical solution in terms of the optimal liquefaction of plantings without a significant loss of the quantitative productivity of the trunk stock of wood and the stability of forest stands. Only as a result of focused efforts can the patterns of natural liquefaction or the process of self-regulation of complex biological systems, to which the forest belong, be achieved. Natural liquefaction of forest stands is an extremely complex process due to its multifactorial nature, to the manifestation of which climatic, soil, biological conditions and many other mutual influences are involved. In forest biogeocenoses, the edifacatory role belongs to the main stand. This tier represents a group of tree species in a phytocenosis, which determines its structure and, to a certain extent, composition. In this study, it is proposed to evaluate the functional load by an indicator of the tension of the living space of the plantation. Since Scotch pine is one of the most common edificators, widely used in the creation of anti-erosion plantations on soils of varying degrees of washout, substantiation of the indicator of tension is carried out on its example. The formula for calculating the tension indicator of the living space, characterizing the growing conditions of the plantation, is given. The indicator of the tension of living space is the ratio of the average height of plantings to their absolute completeness. The verification of the proposed indicator was carried out using tables of the course of growth, highlighting the patterns of the structure of tree stands. A graphic interpretation of the static research of forest stands is carried out. If the values of the tension indicators coincide with the distribution curve obtained from the standard tables of the sum of the cross-sectional areas of tree trunks with a completeness of 1.0, this indicates the optimal use of living space by plantations. The values of the indicators placed above the curve indicate the intensive use of living space. If the values of the indicators are located under the curve - it is incomplete use of living space. Since there is continuous forest management in Ukraine, and for timely forestry measures, it is necessary to constantly monitor the state of plantations. For successful cultivation of anti-erosion plantings of sufficiently high productivity and convenience of monitoring their condition, the proposed indicator can be used.

Structure Of Knowledge

The term epistemological beliefs (EBs) refers to the nature of students’ beliefsof knowledge and learning, these are related to the learning process through their effect on academic performance, motivation and self-regulation. Schommer has argued that the concept is multidimensional and consists of four distinct dimensions, the structure of knowledge, the stability of knowledge, the ability of learning and the speed of learning. The aim of the present study is to explore the structure of epistemic beliefs in a Greek sample, according to the theoretical model of Schommer, and how these beliefs are related to academic performance and other demographic and non demographic variables. The sample was composed by 470 students attending the three gradesof upper high school. The students responded to the Epistemological Belief Questionnaire (Schommer, 2000). The results showed that the structure of the epistemological beliefs is in accordance to Schommer’s theoretical model as regards the four dimensions and that the dimension structure of knowledge was the strongest factor. Low reliability rates lead to doubts regarding Schommer’s conceptual model. Moreover, it was found that ability of learning and stability of knowledge significantly contribute to the prediction ofacademic performance and that higher grades are related to sophisticated EBs. It was also found that girlshave more sophisticated EBs than boys in the speed of learning, and that older students have more sophisticated EBs in the stability of knowledge. Similar findings were found for the students of the theoretical study direction in terms of the stability and the structure of knowledge.

The Impact

Abstract The social benefits of interpersonal synchrony are widely recognized. Yet, little is known about its impact on the self. According to enactive cognitive science, the human self for its stability and regulation needs to balance social attunement with disengagement from others. Too much interpersonal synchrony is considered detrimental for a person’s ability to self-regulate. In this study, 66 adults took part in the Body-Conversation Task (BCT), a dyadic movement task promoting spontaneous social interaction. Using whole-body behavioural imaging, we investigated the simultaneous impact of interpersonal synchrony (between persons) and intrapersonal synchrony (within a person) on positive affect and self-regulation of affect. We hypothesized that interpersonal synchrony’s known tendency to increase positive affect would have a trade-off, decreasing a person’s ability to self-regulate affect. Interpersonal synchrony predicted an increase in positive affect. Consistent with our hypothesis, it simultaneously predicted a weakening in self-regulation of affect. Intrapersonal synchrony, however, tended to oppose these effects. Our findings challenge the widespread belief that harmony with others has only beneficial effects, pointing to the need to better understand the impact of interaction dynamics on the stability and regulation of the human self.

The Relationship

Introduction: We examined if mindsets about the stability (fixed mindset) or malleability (growth mindset) of self-regulation predicted coping with setbacks. We also investigated relations with Executive Function (EF) deficits and ADHD status. Methods: In two correlational studies (Study 1, N = 204; Study 2, N = 184, ADHD, n = 34, Non-ADHD, n = 150), participants reported on their mindsets, self-regulatory abilities, and responded to assessments related to a setback about which they wrote. Results: Across both studies, growth mindsets predicted less negative affect, greater efficacy, and less avoidant coping. The relationship between mindsets and these responses did not depend on EF deficits (Study 1 and Study 2) nor ADHD diagnostic status (Study 2), but participants with greater EF deficits and an ADHD diagnosis reported weaker growth mindsets of self-regulation. Discussion: Findings support the evaluation and development of growth mindset interventions to help individuals with disorders of self-regulation to cope more effectively.

Aim. The aim of the research is to generalize different types of "healthy" narcissistic Self-regulation and to disclose the specific of self-fulfillment and personal life satisfaction. Method. The empirical study involved 360 Ukrainian students (N=360), aged from 17 to 24. The following research methods were used F. W. Deneke and B. Hilgenstock’s Narcissism Inventory (1989), A. Längle and C. Orgler’s Scale of Existence (2003), E. Diener’s Satisfaction with Life Scale (1985), D. Polhus and C. Williams’s "Dark Triad of Personality" questionnaire (2002). The obtained data were processed by multivariate statistics (Statistica 8.0 and Exel), using cluster and comparative analysis (Student's t-test, Scheffe Test). Results. The analysis shows that the most effectively functioning narcissistic self-regulation type is characterized by high narcissism that goes together with the high self-power. The personal fulfillment indicators (such as: self-distance, self-transcendence, freedom, responsibility, existentialism, and personality) are also growing in such conditions. Adequate narcissistic self-regulation goes together with the more meaningful relations with reality and enrichment of the person’s internal emotional life. With the growth of narcissism raises rather positive life acceptance and affirmative attitudes towards “Being” and oneself in it. Conclusions. Narcissistic self-regulation is a mechanism that cares about the stability and integrity of the self-system, makes it possible to accept and appreciate one’s own personality. Only through the prism of prizing oneself (high, but functional narcissism) the value of other people and the world could be seen. This opens the possibility to find and fulfill the meaning of existence.

Intense Debate

Against the background of European standardisation of structural engineering principles, there is intense debate about the extent to which self-regulation and internal inspections can replace independent inspection of calculations relating to static equilibrium, project scheduling and execution of construction work by a third party. There is also discussion about whether the likelihood of errors decreases and, to a certain extent, whether errors would be unlikely or would not have a significant effect on the stability of buildings, as engineers become better qualified. This contribution examines both questions and gives examples from the author’s practical experience.
