Adaptation Patterns on Coastal Communities of the "Gopla" Forest Management Phenomenon at Tasikmadu Village, Trenggalek Regency

Gopla is a coastal community adaptation phenomenon that occurs in the Prigi Beach Area which was pioneered by Mr. Paniyo (Gopla). This phenomenon is a change in deviant behavior where people use forest land that does not belong to them for personal gain. This adaptation is triggered by the increase in the necessities of life caused by the economic crisis and the reduction in basic income from the fisheries and agriculture sectors, which are his main livelihoods. This study has the objectives of 1) knowing the adaptation of coastal communities within the scope of community interaction with forest ecosystems, 2) formulating adaptation patterns that occur in these coastal communities. This study uses a qualitative method with a case study approach. From this research, it was found that the adaptation carried out in the community turned out to include adaptation to the ecosystem, socio-culture, and economic system which are interrelated.

Post-Effect on the Centre of Feet Pressure during Stance by Continuous Asymmetric Mediolateral Translations of a Supporting Platform—A Preliminary Study in Healthy Young Adults

Various diseases are associated with the impaired control of the medio-lateral (ML) position of the centre of feet pressure (CoP), and several manoeuvres have been proposed for enhancing the CoP symmetry. Here, we assessed in healthy standing subjects the feasibility and outcome of a novel protocol entailing a reaction to a continuous asymmetric ML displacement (10 cm) of the support base. The periodic perturbation consisted of a fast half-cycle (0.5 Hz) followed by a slow half-cycle (0.18 Hz). One hundred successive horizontal translation cycles were delivered in sequence. Eyes were open or closed. CoP was recorded before, after, and during the stimulation by a dynamometric platform fixed onto the translating platform. We found that the post-stimulation CoP was displaced towards the direction of the fast half-cycles. The displacement lasted several tens of seconds. Vision did not affect the amplitude or duration of the post-stimulation effect. The magnitude of post-stimulation CoP displacement was related to the perturbation-induced ML motion of CoP recorded during the stimulation. Over the successive perturbation cycles, the time-course of this motion revealed an adaptation phenomenon. Vision moderately reduced the adaptation rate. The findings support the feasibility of the administration of a simple asymmetric balance perturbation protocol in clinical settings to help patients recover the symmetry of the CoP. This protocol needs to be further validated in older populations and in patients.

CONTENT ANALYSIS OF THE ADAPTATION PHENOMENON

Introduction. Modern rapidly changing society requires significant adaptive abilities of a person because the success of both professional and cognitive activities depends on the degree of adaptation. The paper aims to conduct the content analysis of the phenomenon of adaptation. Materials and methods. The philosophical and psychological-pedagogical literature was analyzed, and subsequent generalization was made to accomplish this objective. Research result. The study indicates that adaptation is a process of changing to fit the environment, which can occur at various levels: biological, physiological, psychological, social, social-psychological, and social-pedagogical. Adaptation is an individual process based on the examination of the needs and motives of a person. Furthermore, there is a difference between adaptation as a process and adaptability as a result. There are also several types of adaptation: alloplastic and autoplastic, as well as external and internal. Conclusion. The findings have indicated the main features, approaches, and varieties of the adaptation process; and the characteristic of the phenomenon of adaptation within various forms and categories. Keywords: adaptation, content analysis, social adaptation, behaviorism, humanistic psychology, psychoanalysis, Russian psychology.

Functions of ventral visual cortex after bilateral hippocampal loss

Repeated stimuli elicit attenuated responses in visual cortex relative to novel stimuli. This adaptation phenomenon can be considered a form of rapid learning and a signature of perceptual memory. Adaptation occurs not only when a stimulus is repeated immediately, but also when there is a lag in terms of time and other intervening stimuli before the repetition. But how does the visual system keep track of which stimuli are repeated, especially after long delays and many intervening stimuli? We hypothesized that the hippocampus supports long-lag adaptation, given that it learns from single experiences, maintains information over delays, and sends feedback to visual cortex. We tested this hypothesis with fMRI in an amnesic patient, LSJ, who has encephalitic damage to the medial temporal lobe resulting in complete bilateral hippocampal loss. We measured adaptation at varying time lags between repetitions in functionally localized visual areas that were intact in LSJ. We observed that these areas track information over a few minutes even when the hippocampus is unavailable. Indeed, LSJ and controls were identical when attention was directed away from the repeating stimuli: adaptation occurred for lags up to three minutes, but not six minutes. However, when attention was directed toward stimuli, controls now showed an adaptation effect at six minutes but LSJ did not. These findings suggest that visual cortex can support one-shot perceptual memories lasting for several minutes but that the hippocampus is necessary for adaptation in visual cortex after longer delays when stimuli are task-relevant.

Tracking the Canonical Computations of Perceptual Processing in a Quasi-Continuous Sensory Flow

The canonical computations involved in sensory processing, such as neural adaptation and prediction-error signals, have mainly derived from studies investigating the neural responses elicited by a single stimulus. Here, we test whether these computations can be tracked in a quasi-continuous flow of visual stimulation, by correlating scalp electroencephalography (EEG) recordings to simulations of neuronal populations. Fifteen subjects were presented with ~5,000 visual gratings presented in rapid sequences. Our results show that we can simultaneously decode, from the EEG sensors, up to 4 visual stimuli presented sequentially. Temporal generalization and source analyses reveal that the information contained in each stimulus is processed by a “visual pipeline”: a long cascade of transient processing stages, which can overall encode multiple stimuli at once. Importantly, our data suggest that the early feedforward activity but not the late feedback responses are marked by an adaptation phenomenon. Overall, our approach demonstrates how theoretically-derived computations, as isolated in single-stimulus paradigms, can be generalized to conditions of a continuous flow of sensory information.

Shifts in Adaptation: The Effects of Self-Efficacy and Task Difficulty Perception

The purpose of this study was to explore adaptation through the manipulation of perceived task difficulty and self-efficacy to challenge the concepts postulated by the two-perception probabilistic concept of the adaptation phenomenon (TPPCA) conceptual framework. Twenty-four randomized performers completed a handgrip and putting task, at three difficulty levels, to assess their self-efficacy and perceived task difficulty interactions on motivations, affect, and performances. The TPPCA was partially confirmed in both tasks. Specifically, as the task difficulty level increased, arousal increased, pleasantness decreased, and the performance declined. There was no solid support that motivational adaptations were congruent with the TPPCA. The findings pertaining to the human adaptation state represent a first step in encouraging future inquiries in this domain. The findings clarify the notion of perceived task difficulty and self-efficacy discrepancy, which then provokes cognitive appraisals and emotional resources to produce an adaptation response.

A szabad gyökös reakciók jelentősége a szívizom ischaemiás-reperfúziós károsodásában és az endogén adaptáció indukálásában

The reperfusion of acute ischaemic myocardium is essential for myocardial salvage, so called “gold standard” therapy, however it can results serious damage in the myocardium. Functional alterations occur, including depressed contractile function and decreased coronary flow as well as altered vascular reactivity. Over the several decades it has been demonstrated that oxygen radical formation is greatly increased in post-ischaemic heart and serves as a critical central mechanism of ischaemic-reperfusion injury. However it has been demonstrated that free radical play an important role in the endogenous adaptation phenomenon of the heart, too. Ischaemic preconditioning is a cellular adaptive response of the heart to stress, which provides the most potent endogenous protection against reperfusion arrhytmias, stunning and infarction. Postconditioning defined as brief periods of ischaemia and reperfusion during the very early minutes of reperfusion stimulates endogenous adaptation. Postconditioning may also attenuate the damage to endothelial cells and cardiomyocytes from oxidants, cytokines, proteases and inflammatory cells. Orv. Hetil., 2015, 156(47), 1908–1911.
