AbstractObjective:Executive functions (EF) drive health and educational outcomes and therefore are increasingly common treatment targets. Most treatment trials rely on questionnaires to capture meaningful change because ecologically valid, pediatric performance-based EF tasks are lacking. The Executive Function Challenge Task (EFCT) is a standardized, treatment-sensitive, objective measure which assesses flexibility and planning in the context of provocative social interactions, making it a “hot” EF task.Method:We investigate the structure, reliability, and validity of the EFCT in youth with autism (Autism Spectrum Disorder; n = 129), or attention deficit hyperactivity disorder with flexibility problems (n = 93), and typically developing (TD; n = 52) youth.Results:The EFCT can be coded reliably, has a two-factor structure (flexibility and planning), and adequate internal consistency and consistency across forms. Unlike a traditional performance-based EF task (verbal fluency), it shows significant correlations with parent-reported EF, indicating ecological validity. EFCT performance distinguishes youth with known EF problems from TD youth and is not significantly related to visual pattern recognition, or social communication/understanding in autistic children.Conclusions:The EFCT demonstrates adequate reliability and validity and may provide developmentally appropriate, treatment-sensitive, and ecologically valid assessment of “hot” EF in youth. It can be administered in controlled settings by masked administrators.

The unsatisfactory environmental situation in Ukraine and the world requires the search for new approaches to the management of enterprises aimed at minimizing the negative impact of industrial and economic activities on the environment. Under such conditions, an important task is the formation of appropriate strategies for managing the ecological and innovative activities of enterprises in order to ensure rational decisions regarding the environmental, social and economic sustainability and safety of both individual economic entities and the country as a whole. Ecologically oriented innovation strategies today combine the ideas of ecological innovations, which are the main factor in ensuring ecologically oriented innovative development of companies and, accordingly, sustainable development. Thus, improvement of strategic management of ecological and innovative activities of enterprises is relevant and necessary. An important task is also the use of elements of artificial intelligence in the implementation of the ecological and innovative activity of the enterprise as an open system in order to optimize the management of this activity, the formation of criteria and indicators for evaluating the effectiveness of the system's functioning. The purpose of the article is to study the problems of eco-oriented management of innovative activity and develop proposals for improving the strategic management of eco-innovative activity of enterprises. In order to develop recommendations for improving the strategic management of ecologically innovative activity of enterprises, in accordance with the tasks that were set, the research examines the essence, purpose, main tasks, advantages and principles of eco-oriented management of innovative activities. Indicators characterizing the effectiveness of ecological innovation activity in Ukraine and the world, the degree of ecological innovation activity were analyzed. Approaches to the formation of ecologically oriented innovative strategies are considered. An organizational mechanism for the development of ecologically-oriented innovative strategies and an organizational structure of an intelligent management system for ecologically-oriented innovative enterprises have been developed. The design of an intelligent management system (IMS) of ecologically oriented enterprises (EOE) as a complex system is aimed at ensuring the greening of production and technological processes of economic entities, the greening of industries, regions, and the country in general. It is expedient to focus further research on improving the environmental friendliness of all business processes, actions and operations of EOE with the use of elements of artificial intelligence regarding the adoption of relevant management decisions.

Testo completoAbstract (sommario):
The Ecological Cognition perspective emphasizes the fact that human cognition is adaptive to the constraints of the context of task performance. People are good at developing strategies for task performance that take advantage of the informational affordances of the task environment. Therefore, if we wish to understand human cognition, we must look beyond the skin and skull of the individual to the material and social structures with which the mind interacts. Of course, material artifacts and social arrangements are elements of adaptive processes as well. Material artifacts are often crystallizations of regularities in the task environment and they develop over time, changing adaptively to fit the constraints of the task, the properties of the task performers, and the other artifacts employed in the task performance. Such changes in the material artifacts change the informational affordances of the task environment, which creates new opportunities for the development of strategies. Thus, human cognition and the material supports of human cognition must be seen as a co-adaptive system. Similarly, in complex work settings where two or more persons jointly perform tasks, social arrangements are enacted anew each time a socially distributed task is performed. Strategies for the social division of cognitive labor are also part of this co-adaptive system, both constraining and being constrained by mental and material artifacts. These interlocked co-adaptive systems suggest a cognitive ecology. It's a compelling way of talking about such systems. Can it be more than a metaphor?

Testo completoAbstract (sommario):
The musical Stroop task is analyzed and compared to the classical Stroop task. The analysis indicates that the two tasks differ in the following significant characteristics: ecological validity, the interrelations between the two perceptual dimensions involved, the nature of the automatic process and the existence of a potential Garner interference. It is concluded that the musical task has no advantage over the classical task.

Testo completoAbstract (sommario):
Episodic Memory (EM) allows us to revive a past event through mental time-travel. The neural correlates of memories recollection have been identified in hippocampal regions and multiple neocortical areas, but few neuroimaging studies have used an ecological task such as a free recall of a structured story. Using an ecological fMRI-free recall (FR) task, we aimed to investigate the relevant recruitment of the brain networks associated with the story recollection process and its performance. Fourteen healthy participants listened to a brief story and were tested for Immediate-Recall (IR), a task that is widely used in a neuropsychological evaluation. Then, the subjects underwent an fMRI session, where they had to perform a free recall (FR) of the story subvocally. Finally, the participants were tested for Delayed-Recall (DR). IR and DR scores were significantly (r = 0.942; p < 0.001) correlated. FR enhanced the activity of the Language, the Left Executive Control, the Default Mode and the Precuneus brain networks, with the strongest BOLD signal localized in the left Angular Gyrus (AG) (p < 0.05; FWE-corrected). Furthermore, the story recall performance covaried with specific network activation patterns and the recruitment of the left anterior/posterior AG correlated, respectively, with higher/lower performance scores (p > 0.05). FR seems to be a promising task to investigate ecologically the neural correlates of EM. Moreover, the recruitment of the anterior AG might be a marker for an optimal functioning of the recall process. Preliminary outcomes lay the foundation for the investigation of the brain networks in the healthy and pathological elderly population during FR.

Testo completoAbstract (sommario):
This study was designed to investigate how the classroom ecology (interactions among task systems) and program of action influence participants’ understandings of misbehavior in a middle school physical education setting. One teacher and 14 students participated in a 10-day basketball unit with 47- minute classes. Data included fieldnotes, stimulated recall using videotapes, and semi-structured teacher and student pre- and post-unit interviews. Data were first analyzed inductively by constant comparison (Strauss & Corbin, 1998) and then by using Doyle’s (1986) classroom ecology model to understand the inductively generated categories. Data trustworthiness involved prolonged engagement, member checks, and triangulation. Results indicated that the teacher’s weak managerial task system, coupled with vague and incomplete instructional tasks, interacted with a student social system grounded in various forms of talk as social tasks to support a social program of action. Both teacher and student actions jointly created a primary social vector characterizing the overall program of action.

Testo completoAbstract (sommario):
Although neural visual processes play a crucial role in sport, experiments have been restricted to laboratory conditions lacking ecological validity. Therefore, this study examined the feasibility of measuring visual evoked potentials in a sport-specific visuomotor task. A total of 18 international elite young table tennis athletes (mean age 12.5 years) performed a computer-based and a sport-specific visuomotor reaction task in response to radial motion-onset stimuli on a computer screen and table tennis balls played by a ball machine, respectively. A 64-channel electroencephalography system identified the N2 and N2-r motion-onset visual evoked potentials in the motion-sensitive midtemporal visual area. Visual evoked potential amplitudes were highly correlated between conditions (N2 r = .72, N2-r r = .74) although significantly lower in the sport-specific task than in the lab-based task (N2 p < .001, N2-r p < .001). The results suggest that sport-specific visual stimulation is feasible to evoke visual potentials. This emphasizes the investigation of visual processes under more ecologically valid conditions in sport and exercise science.

Electronic Thesis or Diss., Université de Toulouse (2023-....), 2024. http://www.theses.fr/2024TLSES116.
Testo completoAbstract (sommario):
Les lésions cérébrales acquises, qu'elles soient traumatiques ou vasculaires, sont à l'origine de déficiences motrices, sensorielles et cognitives. Les troubles des fonctions exécutives contribuent à l'altération de l'accomplissement des tâches en vie quotidienne, et ont un impact majeur sur la qualité de vie et de l'autonomie des patients. Pour compenser ces déficits et améliorer leur autonomie, les patients atteint d'un syndrome dysexécutif nécessitent une prise en charge adaptée et spécifique. Actuellement, les batteries de rééducation et les techniques disponibles présentent souvent une faible validité écologique ce qui limite les possibilités de transfert d'apprentissage vers la vie quotidienne. Afin de favoriser ce transfert, il semble crucial de proposer des interventions impliquant des activités fonctionnelles représentatives de la vie quotidienne. Dans cette perspective, nous avons proposé un entraînement cognitif informatisé (Covirtua Cognition®) simulant des situations réelles dans un environnement virtuel. Le premier objectif de ce travail de thèse a été d'évaluer l'efficacité de ce programme de rééducation sur les performances dans la réalisation des activités de la vie quotidienne en situation réelle (transfert d'apprentissage). Pour cela, deux études en multiples cas uniques (SCED) ont été menées, utilisant comme mesure répétée une échelle d'atteinte d'objectifs individualisés, la Goal Attainment Scale. Ce type d'étude permet d'évaluer l'efficacité d'une intervention cognitive avec un échantillon restreint de patients, en recueillant un grand nombre de mesures répétées tout au long de l'étude. Dans la seconde étude, afin de potentialiser les effets de la rééducation, des stimulations cérébrales ont été appliquées pendant l'entraînement cognitif. L'objectif de cette étude a été d'explorer l'efficacité de cet entrainement cognitif "pseudo-écologique", couplé à des stimulations électriques transcrâniennes de type tRNS (transcranial Random Noise Stimulation), appliqué sur le cortex préfrontal droit, chez des patients cérébrolésés ayant des troubles des fonctions exécutives. Dans cette seconde étude, deux grands axes de recherche ont été définis pour évaluer l'impact de ce programme sur les performances comportementales d'une part et les modifications de l'activité cérébrale mesurée en EEG d'autre part. D'un point de vue comportemental, nous avons évalué les performances, en situation de vie quotidienne, grâce à la Goal Attainment Scale. De plus, le fonctionnement exécutif a été évalué par la batterie de tests informatisés "Test Attentional Performance" avant et après l'intervention. Un dernier article, sous la forme d'une "scoping review", répertorie l'ensemble des critères de jugement principaux, utilisés comme mesures répétées en SCED, pour évaluer l'efficacité d'une intervention cognitive à l'échelle individuelle. Nos résultats mettent en évidence des effets modérés de l'intervention visibles principalement à long terme, tant au niveau comportemental qu'électrophysiologique. De plus, il semble que la stimulation n'ait pas renforcer les effets de l'intervention puisque nous avons retrouvé des résultats similaires dans nos 2 études menées en SCED à savoir une atteinte d'au moins 1 des 3 objectifs fixés pour 8 patients. Enfin, les conclusions de la "scoping review" mettent en évidence l'importance du choix de la mesure répétée dans les études SCED, tout en proposant un outil visuel pour aider dans ce choix. Cette thèse contribue à l'avancée des connaissances de la réadaptation du syndrome dysexécutif, permettant d'affiner le profil de patients répondeurs et non répondeurs afin d'optimiser leurs prises en charge. Par ailleurs, ce travail permet de mieux comprendre l'impact d'un programme cognitif sur l'activité cérébrale. De futures investigations sont nécessaires pour identifier des marqueurs neurofonctionnels, plus objectifs, en EEG, prédicteurs d'une rééducation efficaceAcquired brain injury, whether traumatic or vascular, lead to motor, sensory and cognitive impairments. Executive function disorders contribute to the impairment of daily tasks, significantly impacting patients' quality of life and autonomy. To compensate for these deficits and improve their independence, patients with dysexecutive syndrome require tailored and specific treatment. Currently, available rehabilitation batteries and techniques often lack ecological validity, limiting the transfer learning to daily life. To facilitate this transfer, it is crucial to propose more "ecological" interventions involving functional activities representative of daily life. In this perspective, we proposed a computerized cognitive training (Covirtua Cognition®) simulating real-life situations in a virtual environment. The first objective of the present thesis work was to evaluate the effectiveness of this rehabilitation program on performance in carrying out activities of daily living in real-life situations (transfer of learning). For this purpose, two single-case experimental design studies (SCEDs) were conducted, using an individualized goal attainment scale, the Goal Attainment Scale, as a repeated measure. This type of study allows evaluating the effectiveness of a cognitive intervention with a small sample of patients by collecting a large number of repeated measures throughout the study. In the second study, to enhance the effects of rehabilitation, brain stimulations were applied during cognitive training. The objective of this study was to explore the effectiveness of this "pseudo-ecological" cognitive training, coupled with transcranial Random Noise Stimulation (tRNS) applied to the right prefrontal cortex, in patients with acquired brain injuries with executive function disorders. In this second study, two main research axes were defined to evaluate the impact of this program on behavioral performances on one hand, and changes in brain activity measured by EEG on the other hand. At behavioral level we assessed performances in daily life situations using the Goal Attainment Scale. Additionally, executive functioning was evaluated using the computerized Test of Attentional Performance battery before and after the intervention. A final article, in the form of a scoping review, lists all the main outcome criteria used as repeated measures in SCED studies to evaluate the effectiveness of cognitive intervention at the individual level. Our results highlight moderate effects of the intervention, mainly visible in the long term, on both behavior and electrophysiology. Furthermore, it seems that transcranial stimulation did not enhance the effects of the intervention results were comparable in our two SCED studies, with at least one of the three objectives achieved for 8 patients out of 15 in both cases. Finally, the conclusions of the scoping review highlight the importance of choosing wisely the repeated measure in SCED studies, while providing a visual tool to aid in this choice. This thesis contributes to advancing knowledge on the rehabilitation of dysexecutive syndrome, allowing for the refinement of profiles of responder and non-responder patients to optimize their management. Furthermore, this work helps to better understand the impact of a cognitive program on brain activity. Future investigations are needed to identify more objective neurofunctional markers in EEG as effective rehabilitation predictors

Testo completoAbstract (sommario):
The interaction between exercise and cognitive task performance has been previously examined using cycle ergometer and treadmill running tasks. The interaction between natural (non-constrained) exercise and cognitive task performance has, however, been well less examined. An example of a natural exercise task would be running outdoors on a steep trail where route selection and foot placement are critical for the runner. The performance of runners is examined in a dual trail-running and working memory task. The working memory task involved counting tones, and was performed at both a low workload, in which they were asked to count every fourth low frequency tone and a high workload in which they were asked to count every fourth low, medium and high frequency tone. In experiment 1, runners performed the tone-counting tasks both while running on a steep trail with uneven terrain and while seated (control conditions). In addition, they ran the trail without a cognitive task load. Running distance and counting accuracy significantly decreased during the dual task trials, there was a linear trend the run distance decreased as the task got harder. As the secondary cognitive task demand increased running performance decreased (linear trend). Cognitive performance was only significantly impaired while running for the hard cognitive task (for the easy cognitive task there was no statistically significant difference). Participants reported an increased workload in the dual run-counting task conditions when compared with the seated task conditions. Reports of task focus and feeling of being spent (exhausted) also varied across task conditions. In experiment 2 unconstrained running was conducted in the same manner, on a flat-even terrain track to establish if the route selection and scanning required to negotiate uneven terrain was causing the dual-task interference, or if there is a general interference effect caused by the self-regulatory demands of running, or the direct demands of running itself (exercise). The linear trend of decreased running performance with increased secondary cognitive demand was similar to experiment 1 - the more cognitive load the less distance traveled. The effect on the cognitive task was, however, not evident in experiment 2; there was no statistically significant difference between cognitive task performance in the dual and single-task conditions. The findings outlined in these experiments, demonstrate dual cognitive tasks have a negative effect on running performance, and the cognitive task may also be affected depending on running intensity, particularly where self-paced natural running over terrain is coupled with complex cognitive tasks.

Testo completoAbstract (sommario):
It is not a new question as to whether there might be an ecological ethic. This study examines contemporary efforts to engage this question philosophically. These are found to assume some conception of environmental value, however the way in which it is conceived is seen to have significant implications for the role of philosophy in the question of how we might understand environmental responsibility. If this is to be understood in a substantial sense, thus as more than mere prudent self interest and therefore prompting genuine philosophical questions, then substantial questions about the nature of values and the process of valuing must be addressed. The study shows that addressing these questions requires that we address fundamental questions about the nature of the self, and the way in which the self is constituted by the process of engaging its fundamental goods and values. However, environmental responsibility is found to be something which cannot be understood in terms of a self which engages an environmental good. This is the contemporary notion of the ‘ecological self,’ and it is found to be untenable. It is shown that environmental responsibility, if it is to be tenable in a substantial sense, must be intrinsically part of being a self, such that the task of being environmentally responsible is integrally part of the task of being a self. Kierkegaard provides an account of selfhood as a task, and his account of the self is explored. Courting paradox, Kierkegaard challenges us to understand the self as essentially a matter of both immanence and transcendence. Understanding the self in this way is the means to accommodate the possibility that environmental responsibility is an integral part of selfhood, thus an immanent potential to be realised by the individual rather than something which must be grounded philosophically.

Testo completoAbstract (sommario):
A common and clinically important complication of late stage human immunodeficiency virus Type 1 (HIV-1) infection is HIV-associated neurocognitive disorder (HAND). HAND encompasses three syndromes, HIV-associated asymptomatic neurocognitive impairment (ANI), HIV-1- associated mild neurocognitive disorder (MND), and HIV-1-associated dementia (HAD). It is estimated that 30-60% of all HIV-1 infected individuals will have at least mild neurocognitive impairment (MND), and 10-15% of those will develop HAD. Research conducted outside medicine has focused on identifying the type and pattern of neuropsychological impairments present in people with HAND, and to correlate impairments identified from neuropsychological testing with scores on laboratory-based tests of everyday task performance. Typically, the performance of tasks and routines in daily life occurs in naturalistic contexts, and is orchestrated around the achievement of personally meaningful, needed and/or desired performance goals. It requires that one uses cognitive strategies to attend, perceive, remember, decide, plan and act on intentions within real-world contexts. Little is known about the impact of cognitive information processing strategy application impairments on the performance of meaningful tasks and routines carried out by people with HAND in contexts where performance would naturally occur. This research addressed this gap by investigating the real-world impact of information strategy application disorder in a sample of 30 men diagnosed with HAD, the most severe form of HAND. The home contexts of those in the sample consisted of home, supported living and residential care. The criterion-referenced Perceive, Recall, Plan and Perform (PRPP) System of Task Analysis was used to identify the level of task performance mastery demonstrated by men in the sample (Stage One), and the information processing strategy application errors that impacted on their performances (Stage Two). The Clinical Staging of AIDS Dementia Complex (CSADC) scale was used to identify the level of severity of HAD. A total of seventy one task performances were assessed across the sample in a variety of naturalistic contexts. None of the men in the sample demonstrated mastery of task performance. The mean Mastery score was 30.07%. The predominant type of error made by men as they performed daily life tasks was Timing; they spent too much time completing tasks. This was followed by errors of Accuracy; they made mistakes in what they did. Descriptive analysis of the PRPP Stage Two scores revealed that these men had difficulties across all domains of information processing strategy application but most notably with Plan Quadrant (Mean 30.75%) and Perceive Quadrant (Mean 53.49%) strategy application behaviours. Rasch calibration of the ordinal PRPP Stage Two strategy application scores produced an interval-level linear hierarchy of information processing strategy application difficulties experienced by the group. Men in the sample demonstrated problems sequencing complex tasks, choosing plans and actions, analysing problems encountered, and monitoring sensory changes during performances. Problems were also identified in their abilities to contextualise their performances to fit within time constraints (Contextualises to Duration), and enact plans in a fluid manner (Flows). Differences in performances between men with mild dementia versus those with moderate/severe dementia identified using a 2 x 4 repeated measures ANOVA carried out on the Rasch-calibrated PRPP Stage Two scores revealed similarities in performance across Perceive, Recall, Plan and Perform Quadrants but those with mild dementia performed better overall. Further analyses revealed specific differences in performance between those with mild versus those with moderate/severe dementia. Most striking about the findings was that men at both ends of the dementia spectrum had relatively good Recall Quadrant strategy application capacities (Mean 75.30%). Even those with the lowest total PRPP Stage Two scores, could recognize and use objects, and recall the procedures of known tasks. A statistically significant predictive correlation was found between Plan Quadrant disorders and severity of dementia. This pilot study demonstrated the utility of the PRPP System, a criterion-referenced, occupation-embedded, ecological method of identifying task performance skill and information processing strategy application disorders impacting on performance, for use with people living with HIV/AIDS who have HAD. Identifying the specific impact of information processing strategy application disorders on real-world task performance provides occupational therapists with information necessary to more specifically tailor therapy to the individual performance and participation needs of people with HIV-1-associated dementia.

The ontological question is: given that collaborative activities take place within an environment, what kinds of structure must this environment contain? The response emphasizes the importance of relations which exist between entities, and which connect a given perceiver-actor with the other objects and individuals in its surroundings, and with the relations between those entities. It is held that activities take place within a field of relations. This description draws on the radical empiricist doctrine that relations are real, are external, and are directly perceivable. The present proposal insists that, in addition to being directly perceivable, relations can also be directly acted upon: throwing a ball for a dog is acting on a relation between dog and ball in space. The relational field account of collaboration naturally extends to an account of speaking: people, through their history of acting in an environment populated by other speakers, come to stand in a set of relations with objects and events around them, and these relations can be directly acted upon by others through the use of verbal actions. Verbal actions serve to direct the attention of others to relevant aspects of the environment, and this allows us as speakers to coordinate and manage one another’s activity. The methodological question is this: granting that the environment may be structured as a field of relations, how are we to conduct our empirical investigations, such that we can ask precise questions which lead to useful insights about how a given collaborative activity is carried out in practice? The central issue here concerns the concept of the task. Psychologists are in the habit of using this term quite loosely, to denote the actions of an individual or a group, in a laboratory or outside. This creates confusion in discussions of collaborative phenomena: who is the agent of a ‘collaborative task’? The definition offered here states that a task is a researcher-defined unit of study that corresponds to a change in the structure of the environment that has a characteristic pattern and that is meaningful from the first-person perspective of a particular actor. On this definition, the task is a tool that allows ecological psychologists to carve up the problem space into specific, tractable questions; the task is the equivalent of the cognitivist’s mental module. Task-oriented psychology encourages us to ask the question: which specific resources is the individual making use of in controlling this particular activity? The methodology is developed through an examination of the alarm calling behaviour of vervet monkeys, which is explained in terms of actions on the relational field, and through an analysis of corpus data from a laboratory-based collaborative assembly game. The relational field model promises to provide a way of studying social and collaborative activities on ecological realist principles. The concluding chapter identifies two particular areas in which the model might fruitfully be developed: in the study of learning, and in the theory of designing objects and spaces for interaction.

O'Donovan, Toni M. "Competing agendas : an ecological analysis of jointly constructed task systems in physical education and sport education". Thesis, Loughborough University, 2005. https://dspace.lboro.ac.uk/2134/7709.
Testo completoAbstract (sommario):
This thesis addresses how teachers and pupils jointly constructed a physical education classroom ecology in one case study school. Taking into account the persuasive influences facing young people in contemporary society, this research addresses the complexity of young people's agendas in physical education from a socio-cultural perspective. Situating this study in a physical education class meant that I needed to explore, not only how young people's agendas influenced the classroom ecology, but also how the classroom structure influenced the agendas the young people pursued and how these were manifested during the lesson. This study is concerned primarily with describing and explaining a case of pupil engagement in physical education and to generate at a substantive level (Glaser and Strauss, 1978) theory which can make sense of the events in the one case study school. The aim is to provide some insights into why things happened the way they did and attempt to explain these happenings. The data presented in this study endorse to some extent the values claimed for the implementation of Sport Education. However, the implementation of Sport Education did not lead to all its' advocates claim for it and, although its implementation highlighted that it is possible to modify some of the agendas young people pursue during physical education lessons, I became particularly interested in the circumstances where sport education failed to hold the many benefits it purports to. Having presented these key findings, this thesis concludes with a discussion of the implications for those working with and for young people, and for the design and implementation of policies and practice in relation to physical education. Although I outline the implications of the issues emerging from this study for future practice which, at the very least, we need to consider, this study has made particularly clear the complexities of introducing change in schools.

Testo completoAbstract (sommario):
The research project was formulated to solve serious environmental and possible public health problems in rural and regional areas caused by the common failure of soil disposal systems used for application of effluent from on-site domestic sewage treatment systems. On-site sewage treatment systems adopt a treatment train approach with the associated soil disposal area playing a crucial role. The most common on-site sewage treatment system that is used is the conventional septic tank and subsurface effluent disposal system. The subsurface effluent disposal area is given high priority by regulatory authorities due to the significant environmental and public health impacts that can result from their failure. There is generally very poor householder maintenance of the treatment system and this is compounded by the failure of the effluent disposal area resulting in unacceptable surface and groundwater contamination. This underlies the vital importance of employing reliable science-based site suitability assessment techniques for effluent disposal. The research undertaken investigated the role of soil physico-chemical characteristics influencing the behaviour of effluent disposal areas.
The study was conducted within the Logan City Council area, Queensland State, Australia. About 50% of the Logan region is unsewered and the common type of on-site sewage treatment used is a septic tank with subsurface effluent disposal area. The work undertaken consisted of extensive field investigations, soil sampling and testing, laboratory studies and extensive data analysis.
In the field study, forty-eight sites were investigated for their effluent application suitability. The sites were evaluated based on the soil physico-chemical characteristics. The field investigation indicated that there were nine soil orders in the study area. These soil orders were Dermosols, Chromosols, Kandosols, Kurosols, Vertosols, Sodosols, Tenosols, Rudosols and Anthrosols. The soils in all the investigated sites were acidic soils in the pH range between 5 and 6.5.
The complexity of the large data matrix obtained from the analysis was overcome by multivariate analytical methods to assist in evaluating the soils' ability to treat effluent and to understand the importance of various parameters. The analytical methods selected to serve this purpose were PROMETHEE and GAIA. The analysis indicated that the most suitable soils for effluent renovation are the Kandosols whilst the most unsatisfactory soil order was found to be Podosol. The GAIA analysis was in agreement with quantitative analysis conducted earlier.
An extensive laboratory column study lasting almost one year was undertaken to validate the results of the data analysis from the field investigation. The main objectives of this experiment were to examine the soil behaviour under practical effluent application and to investigate the long-term acceptance rate for these soils. Twelve representative soils were selected for the column experiment from the previously investigated sites and undisturbed soil cores were collected for this purpose. The results from the column study matched closely with the evaluation conducted at the earlier stages of the research. Soil physico-chemical analysis before and after effluent application indicated that the soils' acidity was improved toward neutrality after effluent application. The results indicated that soils have a greater ability to handle phosphorus than nitrogen. The most favorable cation exchange capacity for soils to treat and transmit effluent was between 15 and 40 meq/100g.
Based on the results of the column study, the long-term acceptance rate (LTAR) was determined for the investigated twelve soil types. Eleven out of twelve soils reported specific LTAR values between 0.18-0.22 cm/day. For the duration of the laboratory study, the Podosol order did not reach its LTAR value due to the extremely sandy nature of the soil. The time required to achieve LTAR varied between different soils from 40 to 330 days.
The outcomes of this research was integrated into a soil suitability map for on-site sewage treatment systems for Logan City Council. This will assist the authorities in providing sustainable solutions for on-site systems failure.

Testo completoAbstract (sommario):
From the point of view of the new science of globalism, the problems of the ecological, socio-economic state of the world and countries are considered through the prism of the interaction of the human psyche and society and the inhabited world. The criteria of ecological civilization of countries and peoples are justified. Optimizing the consumption of natural bio-and energy resources is becoming a fundamental environmental factor for sustainable development. The "Law of the maximum for humanity" as the law of the biosphere can be the arbitration court, the neutral force that will explain the historical need for mutual understanding, taking into account the interests of ecology and economy for the survival of man as a biovid on Earth; a new reality will begin to form — the phenomenon of co-residence of the world society with the biosphere. The world's population, its energy and bio-consumption, as well as all living matter on the planet, must correspond to the biological capacity of the Earth and not go beyond its boundaries. The task of the society is to implement a worldview breakthrough at the current stage of development, its own cultural mutation, which in the future will create the basis for adaptive technological and socio-cultural development. The task is to classify the entire Earth as a "Green Book" and to solve systemic environmental problems of a global nature. An integral part of sustainable development should be the principle of "vital consumption" at both the personal and social level, instead of the dominant principle of"expanded production and consumption". The indicator of the" culture of consumption "of natural resources, both at the individual level and at the level of society, should be included as an integral part of the integral indicator in the "True Indicator of Progress" and the "Human Development Index".
The book is interdisciplinary in nature; it is a kind of scientific and philosophical poetic essay intended for teachers and students of universities in the field of sociology, ecology, biology and related fields, as well as for everyone who cares about the future of society.

The analysis and design of a new helicopter man-machine interface for a hypothetical rotary-wing air racer as envisioned by the AHS 2012 student design competition is presented. The associated piloting task was modeled using Cognitive Engineering techniques, namely Hierarchical Task Analysis and Abstraction Hierarchy. It was shown that a better integration of collective and pitch control would ease considerably aggressive helicopter flight under manual control while improving the pilot awareness of the constraints limiting the flight envelope. A specific interface could therefore improve both the safety and the performance of helicopters used under such conditions. A corresponding symbology meant to be drawn on either a Head-Up Display (HUD) or a Helmet-Mounted Display (HMD), was conceived using the outcome of this analysis and Ecological Interface Design guidelines. A qualitative evaluation of the symbology seems to show that such an interface would be useful for helicopter applications requiring high agility and most notably quick longitudinal accelerations and decelerations.

The paper describes procedure and results of evaluation of the Ecological display for monitoring and control of the drum-separators at the RBMK-type NPP. This task is characterized by heavy cognitive workload and insufficient human-machine interface. Trial operation of the proposed Ecological display has been carried out during four months at the full scope simulator of the Leningrad NPP with participation of six licensed control room operators. Four exercises and three realistic scenarios were used to collect experimental data. After execution of the tasks the participants filled the questionnaire.The results from the trial operation demonstrate that the ecological interface essentially quickens response time and execution of tasks (in more than 80% of all cases). The Ecological display provides operator with efficient feedback which ensures moderate increase of accuracy and smoothness of control actions. It was revealed that the use of the ecological interface four time reduces frequency of errors compared with the use of conventional interface. However, the efficiency of the Ecological display depends on situation. We revealed that the additional logical processing and the additional director pointer are required to prevent operator from delays and too sharp control actions

Abstract Nuclear power plant accidents are an important public safety issue, and most accidents occur mainly due to unexpected events of the operator. However, traditional nuclear plant interfaces do not provide operators with the ability to resolve unexpected events. As an interface design method, ecological interface design can improve the situational awareness of operators and is widely used in nuclear power plants and other fields. At the same time, in order to improve the adaptability of the interface structure change, this paper introduces a formative method — Cognitive Work Analysis (CWA). This approach aims to describe the given constraints acting on a complex system from different perspectives and structural levels in order to better show how the system operates, and traditionally consists of five stages: Work Domain Analysis (WDA, which create a set of models that describe how complex systems work and then use those models to guide system design), Control Task Analysis (ConTA, which Build models for known repetitive tasks), Strategy Analysis (StrA, which observe known repetitive activity in more detail), Social Organization & Cooperation Analysis (SOCA, which designed to address team communication and cooperation constraints and boundary conditions), and Worker Competencies Analysis (WCA, which describe the level of cognitive control required by the operator to accomplish different system functional goals and tasks). This article will discuss the framework for the use of these five stages at the ecological interface.

Today, we are more likely to speak and write about the more progressive destruction of land biosphere as a result of irrational economic activities of mankind – the replacement of traditional natural ecosystems by anthropogenic systems (techno-, urban- and agro-systems), discuss the harmonization of the interaction of society and nature, talk about growing socio-political tension and instability on the planet. However, it is not just about understanding the effects of environmental civilization, but also awareness of the psychological and socioeconomic consequences of the brutal destruction of the biosphere, finding ways and means of solving the tasks associated with the ecological crisis, which has already entered the geopolitical level – during the last years there is carried out an intensive research on the effects of the crisis in the biosphere on the system of national interests and state security. The war waged by the Russian Federation against Ukraine is causing serious environmental damage to the Ukrainian state. Combat operations spoil the air, pollute water bodies, destroy forests and unique ecosystems, destroy crops and, in the long run, can cause colossal damage to the ecosystem of the whole Eastern Europe, and shorten the lives of Ukrainians. Key words: biosphere, ecosystem, evolution, ecology, civilization, the Russian-Ukrainian war, safety, problem, ecology.

Testo completoAbstract (sommario):
Given the health, social, and economic upheavals of the COVID-19 pandemic, there is understandable anxiety about another virus, monkeypox, quickly emerging in many countries around the world. In West and Central Africa, where the disease has been endemic for several decades, monkeypox transmission in humans usually occurs in short, controllable chains of infection after contact with infected animal reservoirs. Recent monkeypox infections have been identified in non-endemic regions, with most occurring through longer chains of human-to-human spread in people without a history of contact with animals or travel to endemic regions. These seemingly different patterns of disease have prompted public health investigation. However, ending chains of monkeypox transmission requires a better understanding of the social, ecological and scientific interconnections between endemic and non-endemic areas. This brief is intended to be read in conjunction with the companion brief entitled ‘Social Considerations for Monkeypox Response’.1 In this set of briefs, we lay out social considerations from previous examples of disease emergence to reflect on 1) the range of response strategies available to control monkeypox, and 2) specific considerations for monkeypox risk communication and community engagement (RCCE). These briefs are intended to be used by public health practitioners and advisors involved in developing responses to the ongoing monkeypox outbreak, particularly in non-endemic countries. This brief on RCCE strategies for monkeypox response was written by Megan Schmidt-Sane (IDS), Syed Abbas (IDS), Soha Karam (Anthrologica), and Jennifer Palmer (LSHTM), with contributions from Hayley MacGregor (IDS), Olivia Tulloch (Anthrologica), and Annie Wilkinson (IDS). It was reviewed by Will Nutland (The Love Tank CIC/PrEPster) and was edited by Victoria Haldane (Anthrologica). This brief is the responsibility of SSHAP.

Harmful Algal Research & Response: A National Environmental Science Strategy (HARRNESS), 2024-2034. Woods Hole Oceanographic Institution, luglio 2024. http://dx.doi.org/10.1575/1912/69773.
Testo completoAbstract (sommario):
Harmful and toxic algal blooms (HABs) are a well-established and severe threat to human health, economies, and marine and freshwater ecosystems on all coasts of the United States and its inland waters. HABs can comprise microalgae, cyanobacteria, and macroalgae (seaweeds). Their impacts, intensity, and geographic range have increased over past decades due to both human-induced and natural changes. In this report, HABs refers to both marine algal and freshwater cyanobacterial events. This Harmful Algal Research and Response: A National Environmental Science Strategy (HARRNESS) 2024-2034 plan builds on major accomplishments from past efforts, provides a state of the science update since the previous decadal HARRNESS plan (2005-2015), identifies key information gaps, and presents forward-thinking solutions. Major achievements on many fronts since the last HARRNESS are detailed in this report. They include improved understanding of bloom dynamics of large-scale regional HABs such as those of Pseudo-nitzschia on the west coast, Alexandrium on the east coast, Karenia brevis on the west Florida shelf, and Microcystis in Lake Erie, and advances in HAB sensor technology, allowing deployment on fixed and mobile platforms for long-term, continuous, remote HAB cell and toxin observations. New HABs and impacts have emerged. Freshwater HABs now occur in many inland waterways and their public health impacts through drinking and recreational water contamination have been characterized and new monitoring efforts have been initiated. Freshwater HAB toxins are finding their way into marine environments and contaminating seafood with unknown consequences. Blooms of Dinophysis spp., which can cause diarrhetic shellfish poisoning, have appeared around the US coast, but the causes are not understood. Similarly, blooms of fish- and shellfish-killing HABs are occurring in many regions and are especially threatening to aquaculture. The science, management, and decision-making necessary to manage the threat of HABs continue to involve a multidisciplinary group of scientists, managers, and agencies at various levels. The initial HARRNESS framework and the resulting National HAB Committee (NHC) have proven effective means to coordinate the academic, management, and stakeholder communities interested in national HAB issues and provide these entities with a collective voice, in part through this updated HARRNESS report. Congress and the Executive Branch have supported most of the advances achieved under HARRNESS (2005-2015) and continue to make HABs a priority. Congress has reauthorized the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) multiple times and continues to authorize the National Oceanic and Atmospheric Administration (NOAA) to fund and conduct HAB research and response, has given new roles to the US Environmental Protection Agency (EPA), and required an Interagency Working Group on HABHRCA (IWG HABHRCA). These efforts have been instrumental in coordinating HAB responses by federal and state agencies. Initial appropriations for NOAA HAB research and response decreased after 2005, but have increased substantially in the last few years, leading to many advances in HAB management in marine coastal and Great Lakes regions. With no specific funding for HABs, the US EPA has provided funding to states through existing laws, such as the Clean Water Act, Safe Drinking Water Act, and to members of the Great Lakes Interagency Task Force through the Great Lakes Restoration Initiative, to assist states and tribes in addressing issues related to HAB toxins and hypoxia. The US EPA has also worked towards fulfilling its mandate by providing tools and resources to states, territories, and local governments to help manage HABs and cyanotoxins, to effectively communicate the risks of cyanotoxins and to assist public water systems and water managers to manage HABs. These tools and resources include documents to assist with adopting recommended recreational criteria and/or swimming advisories, recommendations for public water systems to choose to apply health advisories for cyanotoxins, risk communication templates, videos and toolkits, monitoring guidance, and drinking water treatment optimization documents. Beginning in 2018, Congress has directed the U.S. Army Corps of Engineers (USACE) to develop a HAB research initiative to deliver scalable HAB prevention, detection, and management technologies intended to reduce the frequency and severity of HAB impacts to our Nation’s freshwater resources. Since the initial HARRNESS report, other federal agencies have become increasingly engaged in addressing HABs, a trend likely to continue given the evolution of regulations(e.g., US EPA drinking water health advisories and recreational water quality criteria for two cyanotoxins), and new understanding of risks associated with freshwater HABs. The NSF/NIEHS Oceans and Human Health Program has contributed substantially to our understanding of HABs. The US Geological Survey, Centers for Disease Control and Prevention, and the National Aeronautics Space Administration also contribute to HAB-related activities. In the preparation of this report, input was sought early on from a wide range of stakeholders, including participants from academia, industry, and government. The aim of this interdisciplinary effort is to provide summary information that will guide future research and management of HABs and inform policy development at the agency and congressional levels. As a result of this information gathering effort, four major HAB focus/programmatic areas were identified: 1) Observing systems, modeling, and forecasting; 2) Detection and ecological impacts, including genetics and bloom ecology; 3) HAB management including prevention, control, and mitigation, and 4) Human dimensions, including public health, socio-economics, outreach, and education. Focus groups were tasked with addressing a) our current understanding based on advances since HARRNESS 2005-2015, b) identification of critical information gaps and opportunities, and c) proposed recommendations for the future. The vision statement for HARRNESS 2024-2034 has been updated, as follows: “Over the next decade, in the context of global climate change projections, HARRNESS will define the magnitude, scope, and diversity of the HAB problem in US marine, brackish and freshwaters; strengthen coordination among agencies, stakeholders, and partners; advance the development of effective research and management solutions; and build resilience to address the broad range of US HAB problems impacting vulnerable communities and ecosystems.” This will guide federal, state, local and tribal agencies and nations, researchers, industry, and other organizations over the next decade to collectively work to address HAB problems in the United States.
