Texte intégralRésumé :
Mutual aid was a mechanism that emerged under the condition of insufficient factors of production in traditional Chinese society; it aimed to improve the productivity of factors by applying the principle of “deduct from the more-than-sufficient and add to the insufficient.” Mutual aid worked to improve the productivity of factors chiefly because it could lead to high efficiency through the full and economical utilization of factors of production that were given and limited. Unlike the input of modern capital that could result in immediate gain in productivity, mutual aid only led to indirect and passive improvements in productivity. Increased social interaction through mutual aid could further boost laborers’ morale and willingness to compete with one another, thus adding to improved productivity. Finally, mutual aid reduced the time spent on and the consumption of factors of production, thus permitting more farmers to engage in wasteland reclamation, sharpening of farming skills, and construction of water-control projects, which also contributed to agricultural growth.

International Journal of Environmental Research and Public Health 18, no 6 (16 mars 2021) : 3061. http://dx.doi.org/10.3390/ijerph18063061.
Texte intégralRésumé :
This study aims to examine the mechanism of how supportive interaction and facilitator input variety in mutual aid groups impact treatment adherence of young people with chronic health conditions, with consideration of time effects, which have been rarely studied in the existing literature. A stratified random sample of 391 individuals aged 12–45 years with chronic health conditions were recruited from mutual aid groups in Hong Kong and completed both the baseline and 12-month follow-up surveys. The results of the structural equation modeling indicated that supportive interaction and facilitator input variety positively predicted treatment adherence in a delayed condition, whereas members’ treatment adherence in the baseline survey had reversed effects on members’ supportive interaction in the follow-up survey. The findings of this study shed light on the dynamic mechanism of the mutual aid groups and provide important implications to promote better rehabilitation outcomes of young people with chronic health conditions.

Texte intégralRésumé :
In response to the COVID-19 pandemic, networks of community organizers and activists mobilized to support their neighbors as part of mutual aid groups across the United States. Emergent community response is a common phenomenon during crisis, but mutual aid in the pandemic took on a distinct character, drawing on traditions of political and community organizing. Our research into these activities suggests that mutual aid organizing in relation to disaster is growing practice but remains evolving and contested. Drawing on interviews with organizers of mutual aid groups in New York, we identify a series of four dilemmas that mutual aid organizers encountered in their work, with impacts on their organizational strategy and technology choices. We then raise three implications for crisis informatics to support community response to disaster: taking a long view of crises, centering questions of equity, and adopting a transformative vision of emergency response.

Texte intégralRésumé :
This study qualitatively analyzes interactional coping strategies used to managed technostress in the post-adoption stage of information technology implementation at a French legal firm. The nine strategies are participatory, collaborative, conflict resolution, bureaucratic coping (adaptation), perceived contribution to exchange, loyalty, affect, professional respect, and mutual trust. A critical perspective was applied to a longitudinal study of the intervention process. First, a problem with task distribution at the individual level affected the efficacy of perceived contribution strategies to exchange and professional enhancement. Second, a lack of creative interaction between group level colleagues undermined strategies of collaboration, mutual aid and assistance, participatory adaptation, and mutual trust. Third, a lack of digitalization commitment at the organizational level negatively affected conflict resolution and bureaucratic adjustment. Finally, an absence of loyalty and affect strategies was evident.

Texte intégralRésumé :
This study explores the experiences of patients and their guardians suffering from Amyotrophic Lateral Sclerosis (ALS), a rare intractable disease called Lou Gehrig's disease (ALS), by participating in an online patient community activity called 'Lou Gehrig’s Network'. To this end, after diagnosing Lou Gehrig's disease, in-depth interviews were conducted with 10 patients and their guardians participating in the 'Lou Gehrig’s Network' during the course of fighting the disease and analyzed using a grounded theory approach (Strauss & Corbin, 1998). As a result of the study, first, 54 concepts, 33 subcategories and 9 upper categories were derived. Second, a paradigm model for the adaptation process through online community participation after the diagnosis of Lou Gehrig's disease was derived. Specifically, as informal learning, there were learning experiences in indirect experience learning, direct experience learning, and mutual learning. Psychological recovery was also possible by active self-exposure, participation, mutual exchange, and information sharing in the community. Next, the interaction between the members of the Lou Gehrig Network confirmed learning and information exchange, community bond formation, and emotional interaction. Each interaction was deeply linked to each other rather than divided into independent interactions, which affected study participants' learning and psychological recovery. At the same time, the study participants served as mutual aid and mentors in the community. This suggests that mutual dynamics are actively taking place among members within the community. The characteristics of the online patient community, the Lou Gehrig Network, functioned as a self-help group, and at the same time served as a medium for information storage and interaction. Meanwhile, the “Lou Gehrig’s Network” was helping participants learn for life by acting as a learning community. Finally, based on the above results, the significance of this study and suggestions for future research were discussed.

International Journal of Environmental Research and Public Health 18, no 22 (18 novembre 2021) : 12110. http://dx.doi.org/10.3390/ijerph182212110.
Texte intégralRésumé :
While it is well-established that mutual aid groups are effective in the psychological rehabilitation of vulnerable individuals, few studies have thoroughly investigated the dynamic mechanism of how psychological well-being improves through mutual aid groups of young patients with chronic health conditions. In connection with several existing theories (i.e., the helper therapy principle, equity theory, the norm of reciprocity, and the concept of communal relationships), this study aims to: (1) evaluate whether emotional support exchanges (i.e., emotional support reception and provision) mediate the relationship between group interaction and psychological well-being; and (2) compare three potential underlying mechanisms—the mediating role of emotional support provision, equitable reciprocity (i.e., a balance of receiving and providing emotional support, where no party over-benefits or under-benefits), and sequential reciprocity (i.e., repaying the helper or a third party in the future after receiving help)—through a path analysis model. A stratified random sampling procedure with chronic health conditions as the stratifying criterion was used to recruit 391 individuals aged 12–45 years from mutual aid groups in Hong Kong, who completed both the baseline and follow-up surveys over a 12-month interval. The results of the path model revealed significant mediating roles of emotional support provision and sequential reciprocity, not equitable reciprocity. The present study offers theoretical and practical implications for promoting the psychological well-being of young patients with chronic health conditions.

Texte intégralRésumé :
Business negotiation teaching can combine theory and practice closely. The form and content of business negotiation need to have the characteristics of a wide range of knowledge, practicality and systematicness. By integrating negotiation teaching into the study of college courses, it can enhance the active atmosphere in the classroom, enhance the interaction between students and teachers, and between teachers, so that students can enhance their language expression ability and thinking logic ability through this form, and improve their adaptability by learning business negotiation strategies and the ability to use and negotiate skills.

Qadri, Rida. « What's in a Network ? Infrastructures of Mutual Aid for Digital Platform Workers during COVID-19 ». Proceedings of the ACM on Human-Computer Interaction 5, CSCW2 (13 octobre 2021) : 1–20. http://dx.doi.org/10.1145/3479563.
Texte intégralRésumé :
This paper examines the role played by informal mutual aid networks in mediating precarity for gig workers in Jakarta during COVID-19. Using an original survey of 350 mobility platform drivers conducted in May 2020 and a pre-pandemic set of semi-structured interviews with driver communities, I find that mutual aid dispersed through associative, informal labor networks became an essential infrastructure of support for drivers during the pandemic. Most drivers in Jakarta were able to mobilize pre-existing labor networks for extensive material and emotional support. However, results indicate this support was not universally accessible: the pre-pandemic structures of a driver's community and the driver's own participation within the community correlated with the magnitude of community support a driver reported receiving. By putting CSCW literature in conversation with broader literature on informal urbanism, this paper shows how informal labor networks and mutual aid can be a transformative, even outside of formal union structures. By analyzing the forms and limits of these networks this paper also carries lessons in how to build solidarity amongst distributed workforces. At the same time, this study highlights the role of local socio-economic context in shaping gig worker experiences of the pandemic. Thus, it points to the need for more contextually driven analysis of both gig worker precarity and what are deemed effective forms of labor solidarity

Revista Colombiana de Psicología 32, no 2 (1 juin 2023) : 95–113. http://dx.doi.org/10.15446/rcp.v32n2.103633.
Texte intégralRésumé :
This research aims to identify the components associated with the benefits of Mutual Aid Groups (mags). Although they have been singled out by the evidence, specific information on their nuclear components is lacking. Based on the methodological approach of Arksey and O’Malley and the Joanna Briggs Institute, all research studies (Pubmed, Scopus, Scielo, Embase, and Redalyc) and gray literature examining these groups were included. The search was carried out throughout 2022 with the following codes: mutual aid groups; self-help groups. We reviewed 62 papers and 37 were included from a total of 2064 articles. The study shows that the components associated with beneficial results are: active agency, coping strategies, recognition, management of emotions, problem-solving strategies, supportive interaction, trust, self-identity construction, and strengthening of social networks. Thus, it reaffirms that mags are an effective option to address health problems. The application of these components could also contribute to achieve these benefits.

Texte intégralRésumé :
La compétence est une ressource capitale pour les organisations et les individus. Elle est recherchée pour divers objectifs comme la performances, l’acquisition d’avantages compétitifs, etc. La notion de compétence est multidimensionnelle et polysémique. Plusieurs méthodes sont utilisées pour sa recherche comme l'analyse des CV ou des entretiens ou d’autres méthodes automatiques de data-mining ou text-mining, qui sont performantes mais pas suffisantes pour la détecter. Dans notre démarche, nous avons considéré que les interactions, particulièrement celles qui ont lieu dans un contexte d’entraide, rendent compte de ce qu’il se passe au moment du déroulé de l’action. Elles sont potentiellement porteuses d’indices révélant la manifestation de la compétence et procurent un environnement favorable pour son identification. Nous avons exploré la théorie de pragma-linguistique et des actes de langage pour analyser des interactions professionnelles basées sur les communications électroniques médiatisées, dans le but de détecter la manifestation de la compétence. Nous avons proposé une méthodologie nommée "approche d’identification des compétences dans les interactions d’entraide" (AIC-IEA). Nous l’avons implémentée sous environnement python et testée sur un corpus d’interactions d'une communauté d'intérêt traitant des problèmes techniques informatiques. Le système développé pourra être utilisé ou combiné à d’autres méthodes de recherche de la compétence en ayant recours juste à l’exploitation des interactions antérieures particulièrement celles d’entraideThe competence is a capital resource for organizations and individuals. It is sought for various purposes such as performance, acquiring competitive advantages, etc. The concept of competence is multidimensional and polysemous. Several methods are used for its research such as the analysis of curriculum vitae or interviews or other automatic methods using the techniques of data-mining or text-mining, which are effective but not sufficient to detect the competence. In our approach, we considered that interactions, particularly those that take place in a mutual aid context, reflect what is happening at the time of the action. They are potentially carriers of clues revealing the manifestation of the competence and provide a favorable environment for its identification. We explored the theory of pragma-linguistics and speech acts to analyze professional interactions based on mediated electronic communications, with the aim of detecting the manifestation of competence. We have proposed a methodology named competence-identifying approach in mutual aid interactions (CIA-MAI). We implemented it in python environment and tested it on a corpus of interactions within a community of interest dealing with technical computer problems. The system, we have developed, can be used or combined to other methods for researching the manifestation of competence by simply exploring the previous interactions around activities, particularly those of mutual aid

Texte intégralRésumé :
Indiana University-Purdue University Indianapolis (IUPUI)In the fields of formal and informal online adult education, the absence of a social context for instruction has been found to present significant limitations for learner persistence and retention. In the field of online psychoeducational intervention, self-administered and self-paced individualized prevention programs have been developed for delivery to large populations of anonymous users. These delivery models provide limited social context for instructional activities, due in part to the anonymity of their participants. When social interaction is included in their prevention programs through voluntary, asynchronous self-help/mutual aid discussion forums, anonymity may still limit social interaction, in favor of observational learning advantages for self-efficacy appraisals derived from "lurking". When these large-group models have been applied to online psychoeducation intervention programs for the purposes of encouraging mutual aid, interactive participation has been limited. This mixed methods study focused on a model for the design of an online small group psychoeducational intervention that integrated individual and social learning in a parent management training program. Self-paced participation was replaced with facilitator-led participation in an asynchronous discussion forum where topics were prioritized and sequenced with learning content from individual web-based training modules. Social interaction was facilitated through online problem-based learning discussion group. Despite assertions that interactive participation in online psychoeducational discussion forums may only be accomplished once a subscriber threshold of several hundred participants has been reached, this study found that small group participation through the program's integrated design resulted large effects for increases in parent self-agency and reduction of over-reactive, coercive parenting behaviors. Participation in the online problem-based group discussion forum was found to have contributed to participant outcomes when posting characteristics revealed the presence of both mutual aid processes and the application of individual learning module content.

Texte intégralRésumé :
Transport infrastructure and human development coexist in a non-linear relationship. The concept of structural and infrastructural development of society is the first attempt at theoretical justification of this interaction. Particular attention is paid to the study of approaches to the definition of the concepts of "infrastructure", "transport infrastructure", "human development"; analysis of the mechanisms of influence of transport infrastructure on human development and mechanisms of reverse impact; understanding the role of pricing processes in this interaction. Further development of the presented issue can become the basis for a macroeconomic analysis of the "transport infrastructure - human development" ex ante relationship.
For a wide range of readers interested in transport infrastructure issues.

Texte intégralRésumé :
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.

Texte intégralRésumé :
This paper investigates communication, including computer-based speech aids by people with severe cerebral palsy—namely Augmented and Alternative Communication, AAC. The reduced bodily capacities and the “uncontrolled bodies” of CP sufferers make bodily synchronization with their partners a considerable challenge. What is more, the electronic speech aid not only produces a disembodied language (synthetic speech), but also has a massive impact on the mutual corporeal attunement of the participants. It will be shown that these detrimental effects of AAC can lead to a breakdown in temporal, sequential and topical structure, and to interactional failure and lack of understanding. However, there are ways to overcome these risks—for example, a “moderator” who channels and controls co-participants’ activities despite the Augmented/Alternative Communicator’s focus on the machine, even during the production of a complex utterance. Thus the machine can be “embodied,” and the interaction can—despite CP—become an “intercorporeal” one.

Marmodoro, Anna. Aristotelian Powers at Work. Oxford University Press, 2017. http://dx.doi.org/10.1093/oso/9780198796572.003.0005.
Texte intégralRésumé :
This paper puts powers to work by developing a broadly Aristotelian account of causation, built on the fundamental idea (which Aristotle found in Plato, attributed by him to Heraclitus) that causation is a mutual interaction between powers. On this Aristotelian view, causal powers manifest them-selves in dependence on the manifestation of their mutual partners. (See also Heil, this volume; Mumford, this volume; and Martin 2008.) The manifestations of two causal power partners are co-determined, co-varying, and co-extensive in time. (See Marmodoro 2006.) Yet, causation has a direction and is thus asymmetric. This asymmetry is what underpins metaphysically the distinction between causal agent and patient. The proposed Aristotelian analysis of the interaction between mutually manifesting causal powers is distinctive, in that it pays justice to the intuition that there is agency in causation. That is, agency is not a metaphorical way of describing what causal powers do. For some powers, it is a way of being that instantiates the non-anthropomorphic sense in which powers are causal agents. This point is brought out in the paper in relation to the explanation of the concept of change. In an Aristotelian fashion, the paper argues that the distinction be-tween agent and patient in causation is pivotal to offering a realist account of causation that does not reify the interaction of the reciprocal causal partners into a relation. On the proposed view, the interaction between mutually manifesting causal partners consists in the power of one substance being realized in another substance. Specifically, the agent’s causal powers metaphysically belong to the agent, but come to be realized in the patient. The significance of this is that the interaction of the agent’s and the patient’s powers is not a relation; rather, it is an ex-tension of the constitution of the agent onto the patient, which occurs when agent and patient interact and their powers are mutually manifested. Thus the proposed Aristotelian account of causation explains the mutual interaction between manifestation partners—potentiality, agency, and change—as irreducible to one another, but interconnected.

Texte intégralRésumé :
This article focuses on interactions and relationships that start on the Internet. Relationships that begin online pose unique challenges: false identities are easy to create and difficult to verify. Visual and non-verbal cues are typically absent, despite the technical possibilities for video and audio transmissions. Because individuals communicating online are likely to be geographically distant from one another, it is often impossible to rely on mutual acquaintances to vouch for the trustworthiness of a person.

Texte intégralRésumé :
Problems of interaction, which give rise to justice, are structurally problems of game theory, the mathematical theory of interactive decisions. Five problems of interaction are introduced that are all intrinsically important and that help motivate important parts of the discussions in subsequent chapters: the Farmer’s Dilemma, impure coordination, the Stag Hunt, the free-rider problem, and the choice for a powerless party to acquiesce or resist. Elements of noncooperative game theory essential to analyzing problems of justice are reviewed, including especially games in the strategic and extensive forms, the Nash equilibrium, the Prisoner’s Dilemma, and games of incomplete information. Each of the five motivating problems is reformulated game-theoretically. These game-theoretic reformulations reveal precisely why the agents involved would have difficulty arriving at mutually satisfactory resolutions, and why “solutions” for these problems call for principles of justice to guide the agents’ conduct.

Texte intégralRésumé :
Happiness of interpersonal relations stands for mutually developing, mutually enriching, mutually facilitative communication. One of basic themes in world culture is reciprocity in human relations. Various forms interpersonal relations assume different stages in their development, and highly developed forms of interpersonal relations are characterized by intersubjectivity. Intersubjectivity is such form of interaction between people that actualizes aspirations to mutual displays and mutual development of participants’ subjectivity. Dialectics of consent and disagreement in intersubjective relations defines a new perspective of both theoretical analysis and empiric researches. Іntersubjectivity emerges when group discussion evolves into vivid and active process of finding solutions, and wherein participants listen to each other, paving the way for dialogueness.

Texte intégralRésumé :
The transition from physical learning spaces to fully digital learning environments in annus horribilis 2020 has challenged Institutions and educators in re-thinking teaching in a time of crisis. E-learning is now phasing out from the initially "Fight-or-Flight" mode in handling panic during the first lockdowns and is currently trying to cope with the pandemic from a more sustainable long-time perspective. Issues have been enlightened concerning teaching and learning on a broader scale, focusing on the need to reconsider traditional teaching practices that nowadays seem not only obsolete but often incompatible with online teaching and learning. It is crucial to give the students flexibility and several possibilities in how, when, and where they engage with their Institution, curriculum, tasks, and peers. Nevertheless, there is a need for a clear structure or framework to aid and guide the students, providing shared arenas for feedback, teamwork, peer learning and social interaction in both physical, hybrid and fully digital learning environments. Through these contact points, we can build a sense of co-presence and mutual understanding between educators and learners to remove barriers that prevent learning. The notion of "presence" has often been discussed and used as an argument in the comparison between "on campus" and online education, strengthening the position of those who deem e-learning to be less useful and less engaging, namely because of the lack of physical presence. However, Institutions and educators need to recognize the current "state of things" as a part of the new norm and a point of no return. It is a question about combining the qualities of physical "in locus" education and the potential of digital learning in a post-pandemic world. By sharing first impressions from a research project at the Norwegian University of Science and Technology (NTNU), this paper attempts to balance and re-direct the discussion towards extending the notion of presence and human interaction to develop sustainable digital learning environments independently of the pandemic situation.

Texte intégralRésumé :
Abstract In this paper, we address a tracking control problem for the coupled translational and attitude motion of a spacecraft. Specifically, a nonlinear adaptive control law is developed to ensure global asymptotic tracking of the desired translational and attitude trajectories in the presence of unknown mass and inertia parameters of spacecraft. Using the vectrix formalism the translational and attitude dynamics of spacecraft is modeled, where the mutual coupling in the translational and attitude motion induced by their gravitational interaction is duly accounted. The four-parameter quaternion representation is employed to describe the attitude kinematics of spacecraft in order to enable large orientation maneuvers. Based on the structure of the resulting system dynamics, the filtered translational and attitude tracking error dynamics are developed, which facilitate the transformation of second-order translational and attitude motion error dynamics as first-order equations, thus providing a considerable simplification in control law synthesis/analysis. With the aid of two linear operators, the open-loop filtered tracking error dynamics is parameterized such that the unknown mass and inertia parameters of spacecraft are isolated and can be estimated on-line. Using a Lyapunov framework, nonlinear control and adaptation laws are designed that ensure the global asymptotic convergence of the translational and attitude position tracking errors, despite the presence of unknown mass and inertia parameters of spacecraft. In addition, the form of the filtered tracking error reveals the convergence of translational and attitude velocity tracking errors of spacecraft. An illustrative numerical simulation is presented to demonstrate the effectiveness of the proposed control design methodology for the coupled translational and attitude motion control of spacecraft.

Texte intégralRésumé :
Abstract. The induced (drag) resistivity (ρ_D) is calculated numerically in low temperature, large interlayer separation and weak interactive regime for 2D hole-hole (h-h) static interactions using the RPA method, with the geometry of non-homogeneous dielectric medium. Exchange-correlations (XC) and mutual interaction effects are considered in low/high density regime for analysing the drag resistivity. It is found that the drag resistivity is found inhanced on using the XC effects and increases on increasing the effective mass. In Fermi-Liquid regime, drag resistivity is directly proportional to r2/n3 at low temperature. Temperature (T), density (n), interlayer separation (d) and dielectric constant (ϵ2) dependency of drag resistivity is measured and compared to 2D e-e and e-h coupled-layer systems with and without the effect of non-homogeneous dielectric medium.

Texte intégralRésumé :
The interactions of noncoordinated water or ammonia molecules with aromatic rings, as well as coordinated water or coordinated ammonia molecules with aromatic rings have been investigated by searching the Cambridge Structural Database (CSD) and through quantum-chemical calculations. The data from the CSD show that for noncoordinated systems distances between the interacting fragments are the shortest in case of negative C6-aromatic groups and the longest in case of positive C6-aromatic groups. In the case of contacts between coordinated water or ammonia molecules and C6-aromatic group, oppositely charged fragments are mutually closer than the neutral fragments. The DFT calculations for the water/benzene system yield an interaction energy of -2.97 kcal/mol, while for the [Zn(H2O)6]2+/C6H6 system the interaction energy is -14.72 kcal/mol. For the ammonia/benzene system, the DFT calculations yield an interaction energy of -2.28 kcal/mol, while for the [Zn(NH3)6]2+/C6H6 system it is -15.50 kcal/mol. The results show that there is an influence of water or ammonia coordination on OH/π or NH/π interactions; the interactions of coordinated species are significantly stronger. OH/π and NH/π interactions are comparable in both cases. OH/π interactions are slightly stronger than NH/π interactions in the case of noncoordinated molecules due to a higher partially positive charge on the hydrogen atom of the water molecule, but this is not necessarily the case for the coordinated molecules due to additional interactions that can occur between the benzene ring and the other ligands present in the complex.

Texte intégralRésumé :
Recently, excitonic optical nonlinearities in direct-gap-semiconductors have attracted much attention and have been studied extensively [1]. Of particular interest are the nonresonant excitonic nonlinearities for their potential applications to ultrafast all-optical devices. The nonlinear optical properties of exciton systems result, in general, from the deviation of excitons from non-interacting ideal bosons. Not only the mutual interaction between excitons, but also the anharmonic excitonphoton interaction, contribute to the excitonic optical nonlinearity. In this paper we develope a simple theory for nonresonant excitonic optical nonlinearity in two- and three-dimensional semiconductors, treating the above mentioned two kinds of anharmonicity on an equal basis.

Texte intégralRésumé :
In real flows nonstationary phenomena connected with the circumferential non-uniformity of the main flow and those caused by oscillations of blades are observed only jointly. An understanding of the physics of the mutual interaction between gas flow and oscillating blades, and the development of predictive capabilities is essential for improved overall efficiency, durability and reliability. In the study presented the algorithm proposed involves the coupled solution of 3D unsteady flow through a turbine stage and dynamic problem for rotor blades motion by action of aerodynamic forces without separating of outer and inner flow fluctuations. The partially integrated method involves the solution of the fluid and structural equations separately, but information is exchanged at each time step, so that solution from one domain is used as boundary condition for the other domain. 3D transonic gas flow through the mutually moving stator and rotor blades with periodicity on the whole annulus is described by the unsteady Euler conservation equations, which are integrated using the explicit monotonous finite-volume difference scheme of Godunov-Kolgan. The structure analysis uses the modal approach and 3D finite element model of a blade. The blade moving is assumed to be constituted as a linear combination of the first natural modes of blade oscillations with the modal coefficients depending on time. There has been performed the calculation for the last stage of the steam turbine. The numerical results for unsteady aerodynamic forces due to stator-rotor interaction are compared with results obtained with taking into account the blades oscillations. It has investigated the mutual influence of both outer flow nonuniformity and blades oscillations. It has shown that amplitude-frequency spectrum of blade oscillations contains the high frequency harmonics, corresponding to rotor moving past one stator blade pitch, and low frequency harmonics caused by blade oscillations and flow nonuniformity downstream from the blade row. Moreover, the spectrum involves the harmonics which are not multiple to the rotation frequency.

Texte intégralRésumé :
Abstract The socio-technical perspective on engineering system design emphasizes the mutual dynamics between interdisciplinary interactions and system design outcomes. How different disciplines interact with each other depends on technical factors such as design interdependence and system performance. On the other hand, the design outcomes are influenced by social factors such as the frequency of interactions and their distribution. Understanding this co-evolution can lead to not only better behavioral insights, but also efficient communication pathways. In this context, we investigate how to quantify the temporal influences of social and technical factors on interdisciplinary interactions and their influence on system performance. We present a stochastic network-behavior dynamics model that quantifies the design interdependence, discipline-specific interaction decisions, the evolution of system performance, as well as their mutual dynamics. We employ two datasets, one of student subjects designing an automotive engine and the other of NASA engineers designing a spacecraft. Then, we apply statistical Bayesian inference to estimate model parameters and compare insights across the two datasets. The results indicate that design interdependence and social network statistics both have strong positive effects on interdisciplinary interactions for the expert and student subjects alike. For the student subjects, an additional modulating effect of system performance on interactions is observed. Inversely, the total number of interactions, irrespective of their discipline-wise distribution, has a weak but statistically significant positive effect on system performance in both cases. However, excessive interactions mirrored with design interdependence and inflexible design space exploration reduce system performance. These insights support the case for open organizational boundaries as a way for increasing interactions and improving system performance.

Texte intégralRésumé :
The article is an overview of the journalism – PR – advertising relationship at the terminological, empirical-analytical and practical levels. It traces the state of the discussion of these correlations in the post-soviet media such as Ukraine. The study describes that domesticating the importance of the appropriate partnership between the three communication technologies. The thesis is that journalism, advertising and PR create a mutual connection that takes place in an atmosphere of PR and advertising permissiveness and deepens with the development of digitalization, Social network development. The present research is based on a comprehensive approach. The inductive and deductive methods are adopted to discuss theoretical materials, and the interdisciplinary research method is used to detect PR-specific features as a philosophy of a new journalism project. The interpretive approach, usually employed to analyze media text as a complex synthetic structure, was also taken into consideration. The analytical method application identified the modern means of substantiating the ideological, esthetical and informative value of brand journalism and spin doctor. The innovative character of modern media as a behavioral strategy in the advertising and PR industry consists in the fact that it is a form of creative production and behavior rather than adapting a specific communication situation. The article examines the main directions of contemporary interactions between PR, advertising and journalism as a media content creation. In this context, it is asserted that advertising, journalism and PR activities can contribute to the creation of media content. At some point, good media content is achieved not only as a result of this competition but also from the correlation between PR, advertising and journalism.

Texte intégralRésumé :
The communication of naturally complex issues like climate change, tipping points, socio-ecological systems, and their interaction with the hydrological cycle and water security is equally important as it is challenging. Beyond the complexity, the long-term and often delayed characteristics furthermore do not match with either political election cycles or quarterly business reports. Academic institutions are at the forefront to assess, reveal and understand such complex systems, but certainly more engagement is needed to effectively transfer the most urgent derivations in practice and policy on the one hand, but also invest into a continuing effort in creating a general understanding and susceptibility to crucial stakeholders of those characteristics on the other. Transformative interaction, and hence closing the gap between knowledge generation and best practice application needs to be eased down to an implementable level, but without any oversimplification. A prerequisite for such an approach in successful multilateral cooperation would be a common baseline – a mutual Water Culture among all stakeholders when addressing water security with meaningful climate adaptation measures.

Granot, David, Richard Amasino et Avner Silber. Mutual effects of hexose phosphorylation enzymes and phosphorous on plant development. United States Department of Agriculture, janvier 2006. http://dx.doi.org/10.32747/2006.7587223.bard.
Texte intégralRésumé :
Research objectives 1) Analyze the combined effects of hexose phosphorylation and P level in tomato and Arabidopsis plants 2) Analyze the combined effects of hexose phosphorylation and P level in pho1 and pho2 Arabidopsis mutants 3) Clone and analyze the PHO2 gene 4) Select Arabidopsis mutants resistant to high and low P 5) Analyze the Arabidopsis mutants and clone the corresponding genes 6) Survey wild tomato species for growth characteristics at various P levels Background to the topic Hexose phosphorylating enzymes, the first enzymes of sugar metabolism, regulate key processes in plants such as photosynthesis, growth, senescence and vascular transport. We have previously discovered that hexose phosphorylating enzymes might regulate these processes as a function of phosphorous (P) concentration, and might accelerate acquisition of P, one of the most limiting nutrients in the soil. These discoveries have opened new avenues to gain fundamental knowledge about the relationship between P, sugar phosphorylation and plant development. Since both hexose phosphorylating enzymes and P levels affect plant development, their interaction is of major importance for agriculture. Due to the acceleration of senescence caused by the combined effects of hexose phosphorylation and P concentration, traits affecting P uptake may have been lost in the course of cultivation in which fertilization with relatively high P (30 mg/L) are commonly used. We therefore intended to survey wild tomato species for high P-acquisition at low P soil levels. Genetic resources with high P-acquisition will serve not only to generate a segregating population to map the trait and clone the gene, but will also provide a means to follow the trait in classical breeding programs. This approach could potentially be applicable for other crops as well. Major conclusions, solutions, achievements Our results confirm the mutual effect of hexose phosphorylating enzymes and P level on plant development. Two major aspects of this mutual effect arose. One is related to P toxicity in which HXK seems to play a major role, and the second is related to the effect of HXK on P concentration in the plant. Using tomato plants we demonstrated that high HXK activity increased leaf P concentration, and induced P toxicity when leaf P concentration increases above a certain high level. These results further support our prediction that the desired trait of high-P acquisition might have been lost in the course of cultivation and might exist in wild species. Indeed, in a survey of wild species we identified tomato species that acquired P and performed better at low P (in the irrigation water) compared to the cultivated Lycopersicon esculentum species. The connection between hexose phosphorylation and P toxicity has also been shown with the P sensitive species VerticordiaplumosaL . in which P toxicity is manifested by accelerated senescence (Silber et al., 2003). In a previous work we uncovered the phenomenon of sugar induced cell death (SICD) in yeast cells. Subsequently we showed that SICD is dependent on the rate of hexose phosphorylation as determined by Arabidopsis thaliana hexokinase. In this study we have shown that hexokinase dependent SICD has many characteristics of programmed cell death (PCD) (Granot et al., 2003). High hexokinase activity accelerates senescence (a PCD process) of tomato plants, which is further enhanced by high P. Hence, hexokinase mediated PCD might be a general phenomena. Botrytis cinerea is a non-specific, necrotrophic pathogen that attacks many plant species, including tomato. Senescing leaves are particularly susceptible to B. cinerea infection and delaying leaf senescence might reduce this susceptibility. It has been suggested that B. cinerea’s mode of action may be based on induction of precocious senescence. Using tomato plants developed in the course of the preceding BARD grant (IS 2894-97) and characterized throughout this research (Swartzberg et al., 2006), we have shown that B. cinerea indeed induces senescence and is inhibited by autoregulated production of cytokinin (Swartzberg et al., submitted). To further determine how hexokinase mediates sugar effects we have analyzed tomato plants that express Arabidopsis HXK1 (AtHXK1) grown at different P levels in the irrigation water. We found that Arabidopsis hexokinase mediates sugar signalling in tomato plants independently of hexose phosphate (Kandel-Kfir et al., submitted). To study which hexokinase is involved in sugar sensing we searched and identified two additional HXK genes in tomato plants (Kandel-Kfir et al., 2006). Tomato plants have two different hexose phosphorylating enzymes; hexokinases (HXKs) that can phosphorylate either glucose or fructose, and fructokinases (FRKs) that specifically phosphorylate fructose. To complete the search for genes encoding hexose phosphorylating enzymes we identified a forth fructokinase gene (FRK) (German et al., 2004). The intracellular localization of the four tomato HXK and four FRK enzymes has been determined using GFP fusion analysis in tobacco protoplasts (Kandel-Kfir et al., 2006; Hilla-Weissler et al., 2006). One of the HXK isozymes and one of the FRK isozymes are located within plastids. The other three HXK isozymes are associated with the mitochondria while the other three FRK isozymes are dispersed in the cytosol. We concluded that HXK and FRK are spatially separated in plant cytoplasm and accordingly might play different metabolic and perhaps signalling roles. We have started to analyze the role of the various HXK and FRK genes in plant development. So far we found that LeFRK2 is required for xylem development (German et al., 2003). Irrigation with different P levels had no effect on the phenotype of LeFRK2 antisense plants. In the course of this research we developed a rapid method for the analysis of zygosity in transgenic plants (German et al., 2003).

Texte intégralRésumé :
Economic reasons are among the basic explanatory factors of migration, whether international or internally within a country. In turn, migratory movements have effects on the economy in terms of economic growth in general, but also in the different markets (work, housing, consumer goods, etc.) and public services (education, health, social services, etc.). The purpose of this document is to offer an overview of these interactions between migration and the economy in the case of the Canary Islands. To do this, certain conceptual clarifications will be made initially involving the mutual determination of both processes, before later providing specifics with evidence on the Canarian case for the main issues considered: the economic reasons for migration, and its impact on economic growth, the labour market and the living conditions of the immigrant population. The final section alludes to the importance of the institutional framework that regulates these relations between migration and the economy, which are far from being interpretable as a mechanical relationship and isolated from the political sphere.

Texte intégralRésumé :
When an inmate leaves prison following a sentence for terrorism offenses, their reintegration will depend on whether they can function as a relatively social member of their community. Obstacles such as stigmatization exist for all former convicts, but among steadfast extremists these barriers will be mutual, if they continue to perceive the ingroup-outgroup dichotomy that fed their extremism in the first place. A simple but effective means for determining the likelihood that returning prisoners will act prosocially towards the ‘other’ could be the use of so-called lab-in-field games, which provide small incentives to learn how individuals behave in a given situation, rather than just eliciting their sentiment. This chapter outlines the potential for such an approach. It draws on field research conducted in Indonesia in 2018, which involved interviews with 28 former convicted terrorists, regarding their practical experiences with reintegration and interactions in the community.

Texte intégralRésumé :
The size and shape of plant leaves are extremely diverse within and among species, and are also sensitive to growth conditions. Compound leaves, such as those of tomato, maintain morphogenetic activity during early stages of their development, enabling them to elaborate lateral appendages such as leaflets. The aim of the research project was to understand the interaction between the plant hormone auxin, the putative auxin response inhibitor ENTIRE (E, SlIAA9) and the NAM/CUC transcription factor GOBLET (GOB) in compound-leaf development in tomato (Solanum lycopersicum). The specific aims of the project were: 1. Investigation of the role of GOB in compound-leaf development. 2. Characterization of E function in auxin signaling. 3. Characterization of the role of auxin in compound-leaf development. 4. Investigation of the genetic and molecular interaction between E and GOB. 5. Investigate the role of these factors in fruit development. There were no major changes in these objectives. GOB was shown to mark and promote the boundaries between the leaf and initiating leaflets. Its accurate distribution was found to be required for proper leaflet initiation and separation. E was found to interact with the TIR1 and AFB6 proteins in an auxin-dependant manner, indicating that these are functional auxin receptors that mediate E degradation in the presence of auxin. This was further supported by the stabilization of E by a mutation in domain II of the protein, which is thought to mediate its auxin-dependant degradation. Over expression of this stabilized form in tomato leaves and characterization of the e mutant phenotype and the E expression domain indicated that E acts between initiating leaflets to inhibit auxin response and lamina growth. Generation and analysis of tomato plants expressing the auxin response reporter DR5::VENUS, and analysis of the effect of auxin microapplication or overexpression of an auxin biosynthesis gene, indicated that auxin marks the sites of leaflet initiation and promotes lamina growth. Investigation of the molecular and genetic interaction between auxin, GOB and E revealed a complex network of mutual regulation that is utilized to precisely pattern the leaf margin in a manner that enables the combination of tight control and flexibility. E, auxin and GOB were shown to affect fruit development and fruit set, and in an extension of the project are currently utilized to identify new players that affect these processes. The research project yielded enhanced understanding of the mechanisms of compound leaf patterning and provided tools that will enable the manipulation of leaf shape and fruit set.

Texte intégralRésumé :
In the original proposal we planned to focus on two proteins related to the actin cytoskeleton: TCH2, a touch-induced calmodulin-like protein which was found by us to interact with the IQ domain of myosin VIII, ATM1; and ERD10, a dehydrin which was found to associate with actin filaments. As reported previously, no other dehydrins were found to interact with actin filaments. In addition so far we were unsuccessful in confirming the interaction of TCH2 with myosin VIII using other methods. In addition, no other myosin light chain candidates were found in a yeast two hybrid survey. Nevertheless we have made a significant progress in our studies of the role of myosins in plant cells. Plant myosins have been implicated in various cellular activities, such as cytoplasmic streaming (1, 2), plasmodesmata function (3-5), organelle movement (6-10), cytokinesis (4, 11, 12), endocytosis (4, 5, 13-15) and targeted RNA transport (16). Plant myosins belong to two main groups of unconventional myosins: myosin XI and myosin VIII, both closely related to myosin V (17-19). The Arabidopsis myosin family contains 17 members: 13 myosin XI and four myosin VIII (19, 20). The data obtained from our research of myosins was published in two papers acknowledging BARD funding. To address whether specific myosins are involved with the motility of specific organelles, we cloned the cDNAs from neck to tail of all 17 Arabidopsis myosins. These were fused to GFP and used as dominant negative mutants that interact with their cargo but are unable to walk along actin filaments. Therefore arrested organelle movement in the presence of such a construct shows that a particular myosin is involved with the movement of that particular organelle. While no mutually exclusive connections between specific myosins and organelles were found, based on overexpression of dominant negative tail constructs, a group of six myosins (XIC, XIE, XIK, XI-I, MYA1 and MYA2) were found to be more important for the motility of Golgi bodies and mitochondria in Nicotiana benthamiana and Nicotiana tabacum (8). Further deep and thorough analysis of myosin XIK revealed a potential regulation by head and tail interaction (Avisar et al., 2011). A similar regulatory mechanism has been reported for animal myosin V and VIIa (21, 22). In was shown that myosin V in the inhibited state is in a folded conformation such that the tail domain interacts with the head domain, inhibiting its ATPase and actinbinding activities. Cargo binding, high Ca2+, and/or phosphorylation may reduce the interaction between the head and tail domains, thus restoring its activity (23). Our collaborative work focuses on the characterization of the head tail interaction of myosin XIK. For this purpose the Israeli group built yeast expression vectors encoding the myosin XIK head. In addition, GST fusions of the wild-type tail as well as a tail mutated in the amino acids that mediate head to tail interaction. These were sent to the US group who is working on the isolation of recombinant proteins and performing the in vitro assays. While stress signals involve changes in Ca2+ levels in plants cells, the cytoplasmic streaming is sensitive to Ca2+. Therefore plant myosin activity is possibly regulated by stress. This finding is directly related to the goal of the original proposal.
