Human-AI ecosystem with abrupt changes as a function of the composition.

The progressive advent of artificial intelligence machines may represent both an opportunity or a threat. In order to have an idea of what is coming we propose a model that simulate a Human-AI ecosystem. In particular we consider systems where agents present biases, peer-to-peer interactions and also three body interactions that are crucial and describe two humans interacting with an artificial agent and two artificial intelligence agents interacting with a human. We focus our analysis by exploring how the relative fraction of artificial intelligence agents affect that ecosystem. We find evidence that for suitable values of the interaction parameters, arbitrarily small changes in such percentage may trigger dramatic changes for the system that can be either in one of the two polarised states or in an undecided state.

Questionnaire-based study evaluating awareness for organ and body donation and cadaveric dissection among the general population attending mid Gujarat region

Introduction: Organ transplantation provides benefits to society as a whole as well as to the individuals who receive transplants. However, the success of transplantation for end-stage organ failure is limited due to the availability of suitable organs for transplant Public awareness is critical for the development of donation program. Methods: Total 200 adult participants were included in the studies from outpatient department by consecutive sampling method. A self-administered semi structured questionnaire was filled by participants in the presence of researchers. Results: Awareness of organ donation (67.5%) was higher than awareness of body donation (34.5%) and cadaveric dissection (32.5%). About 28% and 24% participants were aware of live organ donation and brain death. Willingness for organ donation was observed 21.5% participants, unwillingness in 51.5% of participants and 27.0% in undecided state of mind. Conclusion: Knowledge level regarding organ donation was found sufficient but same did not reflect in their attitude and practice towards organ donation. Educational session of health care professional through internet and television can play critical role in rising up positive attitude towards organ donation. Fear of misuse of donated organ is the most common reason for unwillingness to be a donor.

Repulsion in controversial debate drives public opinion into fifty-fifty stalemate.

Opinion formation is a process with strong implications for public policy. In controversial debates with large consequences, the public opinion is often trapped in a fifty-fifty stalemate, jeopardizing broadly accepted political decisions. Emergent effects from millions of private discussions make it hard to understand or influence this kind of opinion dynamics. Here we demonstrate that repulsion from opinions favors fifty-fifty stalemates. We study a voter model where agents can have two opinions or an undecided state in between, and where we allow for repulsion of opinions and for doubt: in pairwise discussions, undecided agents can be not only convinced, but also repelled from the opinion expressed by another agent, and decided agents may return to the undecided state. As a result, we observe that, if an agent is repelled instead of being convinced in at least one out of four interactions, as in controversial debates, the frequencies of both opinions equalize. This voter model attractor reproduces the phenomenology of repeated Brexit poll data well and provides a mechanism solely based on local interactions between agents that may explain stalemate polarization in controversial opinion formation.

Impact of network randomness on multiple opinion dynamics

People often face the challenge of choosing among different options with similar attractiveness. To study the distribution of preferences that emerge in such situations, a useful approach is to simulate opinion dynamics on top of complex networks, composed by nodes (individuals) and their connections (edges), where the state of each node can be one amongst several opinions including the undecided state. We analyze two different dynamics: the one proposed by Travieso and Fontoura (TF) and the plurality rule (PR), which are paradigmatic of outflow and inflow dynamics, respectively. We are specially interested in the impact of the network randomness on the final distribution of opinions. For that purpose, we consider Watts–Strogatz networks, which possess the small-world property, and where randomness is controlled by a probability p of adding random shortcuts to an initially regular network. Depending on the value of p, the average connectivity 〈k〉, and the initial conditions, the final distribution can be basically (i) consensus, (ii) coexistence of different options, or (iii) predominance of indecision. We find that, in both dynamics, the predominance of a winning opinion is favored by increasing the number of reconnections (shortcuts), promoting consensus. In contrast to the TF case, in the PR dynamics, a fraction of undecided nodes can persist in the final state. In such cases, a maximum number of undecided nodes occurs within the small-world range of p, due to ties in the decision group.

Balancing a genetic toggle switch by real-time feedback control and periodic forcing

Cybergenetics is a novel field of research aiming at remotely pilot cellular processes in real-time with to leverage the biotechnological potential of synthetic biology. Yet, the control of only a small number of genetic circuits has been tested so far. Here we investigate the control of multistable gene regulatory networks, which are ubiquitously found in nature and play critical roles in cell differentiation and decision-making. Using an in silico feedback control loop, we demonstrate that a bistable genetic toggle switch can be dynamically maintained near its unstable equilibrium position for extended periods of time. Importantly, we show that a direct method based on dual periodic forcing is sufficient to simultaneously maintain many cells in this undecided state. These findings pave the way for the control of more complex cell decision-making systems at both the single cell and the population levels, with vast fundamental and biotechnological applications.

Role of the plurality rule in multiple choices

People are often challenged to select one among several alternatives. This situation is present not only in decisions about complex issues, e.g. political or academic choices, but also about trivial ones, such as in daily purchases at a supermarket. We tackle this scenario by means of the tools of statistical mechanics. Following this approach, we introduce and analyse a model of opinion dynamics, using a Potts-like state variable to represent the multiple choices, including the ‘undecided state’, which represents the individuals who do not make a choice. We investigate the dynamics over Erdös–Rényi and Barabási–Albert networks, two paradigmatic classes with the small-world property, and we show the impact of the type of network on the opinion dynamics. Depending on the number of available options q and on the degree distribution of the network of contacts, different final steady states are accessible: from a wide distribution of choices to a state where a given option largely dominates. The abrupt transition between them is consistent with the sudden viral dominance of a given option over many similar ones. Moreover, the probability distributions produced by the model are validated by real data. Finally, we show that the model also contemplates the real situation of overchoice, where a large number of similar alternatives makes the choice process harder and indecision prevail.

Courting the Swing Voter

This essay reports the results of an analysis of undecided swing state voters during the six presidential debates of the 2008 and 2012 elections. Combining Real Time Response with a pretest-posttest design, the researchers identify the overall impact of the debates on undecided voters, both successful and unsuccessful message strategies, and changes in the overall perception of the candidates.

Role of noise and agents’ convictions on opinion spreading in a three-state voter-like model

In this work we study opinion formation in a voter-like model defined on a square lattice of linear size L. The agents may be in three different states, representing any public debate with three choices (yes, no, undecided). We consider heterogeneous agents that have different convictions about their opinions. These convictions limit the capacity of persuasion of the individuals during the interactions. Moreover, there is a noise p that represents the probability of an individual spontaneously changing his opinion to the undecided state. Our simulations suggest that the system reaches stationary states for all values of p, with consensus states occurring only for the noiseless case p = 0. In this case, the relaxation times are distributed according to a log-normal function, with the average value τ growing with the lattice size as τ ∼ Lα, where α ≈ 0.9. We found a threshold value p* ≈ 0.9 above which the stationary fraction of undecided agents is greater than the fraction of decided ones. We also study the consequences of the presence of external effects in the system, which models the influence of mass media on opinion formation.

States of Suspension: Trans-corporeality at Sea

To suspend: “To debar temporarily, especially from a privilege.” “To hold in an undetermined or undecided state awaiting further information.” “To keep from falling or sinking by some invisible support as buoyancy.” “To keep fixed or lost (as in wonder or contemplation).” In Bodily Natures: Science, Environment, and the Material Self, I argue for a conception of trans-corporeality that traces the material interchanges across human bodies, animal bodies, and the wider material world. As the material self cannot be disentangled from networks that are simultaneously economic, political, cultural, scientific, and substantial, what was once the ostensibly bounded human subject finds herself in a swirling landscape of uncertainty where practices and actions that were once not even remotely ethical or political matters suddenly become so. Trans-corporeality is a new materialist and posthumanist sense of the human as substantially and perpetually interconnected with the flows of substances and the agencies of environments. Activists, as well as everyday practitioners of environmental, environmental health, environmental justice, and climate change movements, work to reveal and reshape the flows of material agencies across regions, environments, animal bodies, and human bodies—even as global capitalism and the medical–industrial complex reassert a more convenient ideology of solidly bounded, individual consumers and benign, discrete products. Even though the recognition of trans-corporeality begins with human bodies in their environments, tracing substantial interchanges renders the human permeable, dissolving stable outlines. Tracing these connections discourages us from taking refuge in the fantasies of transcendence and imperviousness that make environmentalism a merely elective and external enterprise.

Systems biology of stem cells: three useful perspectives to help overcome the paradigm of linear pathways.

Stem cell behaviours, such as stabilization of the undecided state of pluripotency or multipotency, the priming towards a prospective fate, binary fate decisions and irreversible commitment, must all somehow emerge from a genome-wide gene-regulatory network. Its unfathomable complexity defies the standard mode of explanation that is deeply rooted in molecular biology thinking: the reduction of observables to linear deterministic molecular pathways that are tacitly taken as chains of causation. Such culture of proximate explanation that uses qualitative arguments, simple arrow-arrow schemes or metaphors persists despite the ceaseless accumulation of 'omics' data and the rise of systems biology that now offers precise conceptual tools to explain emergent cell behaviours from gene networks. To facilitate the embrace of the principles of physics and mathematics that underlie such systems and help to bridge the gap between the formal description of theorists and the intuition of experimental biologists, we discuss in qualitative terms three perspectives outside the realm of their familiar linear-deterministic view: (i) state space (ii), high-dimensionality and (iii) heterogeneity. These concepts jointly offer a new vista on stem cell regulation that naturally explains many novel, counterintuitive observations and their inherent inevitability, obviating the need for ad hoc explanations of their existence based on natural selection. Hopefully, this expanded view will stimulate novel experimental designs.

Pirsig's ‘ Zen and the Art of Motorcycle Maintenance’: Quality, reason and binary opposites

Robert Pirsig's celebrated novel has lost little of its impact after 30 plus years, and still speaks to us in the West and our highly technological society. None of the issues raised regarding our relation with technology have changed. As fits the schizophrenic pattern of the book, this article is arbitrarily divided into two disparate sections: the first covers some of the sources for the book and the range of critical views on the book. The second, a more speculative conclusion, drawing on a contradiction in Pirsig's text, looks forward to the books continuing relevance as we see the promise of a new dawn for computers: quantum computing. I am unsure of how to equate the forceful rhetoric against dualism, with the facile mystical acceptance of the Buddha residing in the circuits of a digital computer. This fracture in Pirsig's work becomes more visible when he talks of the Japanese term ‘ mu’, meaning ‘no thing’. Binary computation is challenged by alternative logics to binary logic. I examine these issues along with the current definitions of Pirsig's quality. A future ‘definition’ of Pirsig's Quality could be the undecided state of a quantum computer (or quantum processes in the mind).

Concurrent Evaluation of Career Indecision and Indecisiveness

Career indecision is reconceptualized as a complex, multidimensional problem composed of an undecided state and an indecisive trait.

The Library World Volume 44 Issue 1

JUNE, from the enemy aerial view, has been a quiet month. Hitler, as was demonstrated on June 22nd, had turned his attention to Russia, and so more English libraries have not been added to his bag. The lull has given some of us a space in which to clear out debris and to get our damaged libraries more shipshape. In this, our new volume (Vol. xliv. No. 500), we glance rapidly back over a momentous year. It is difficult to realize that eleven months ago not a volume had been lost or a brick displaced in British libraries; that, in spite of the agony and triumph of Dunkirk, out attacks on Germany had been mainly of the paper kind; and that most, but by no means all, of our young librarians were still with us. The change has been great. True, the Battle of Britain, 1940, was won; but the night bomber introduced death and disaster unprecedented in this country, though well‐known in invaded lands. We went to bed at night hopeful and woke thankful, but not certain that there would be an awakening. Libraries suffered with other military objectives such as the small homes of suburban and country folk. We have been praised by our American brethren as heroic, and that is pleasant to hear, but we have not felt heroic; we have stood up to it because no other course is possible or thinkable. The problems of librarians in evacuation areas have been great; large numbers of their people migrated, and in some cases there were defence areas to which no visitor might go; falling revenues made existence almost impossible, and staffs were dismissed or transferred, the posts of librarians of years of service being endangered. Yet these sent out books for children in reception areas where, of their own kind, the problems were also great. Some libraries were overwhelmed by the demands made upon them, and although some towns (for example, Newton Abbot) have been prosperous beyond their experience as a result of the new settlers, the local authorities have had such “war economy” in their minds that they have been unwilling to do their obvious duty to libraries. This was, however, not universal. The year saw, unfortunately, the beginning of the new Roll of Honour for librarians, which in this case contains a few names of those killed in air raids over us; some, too, have been injured, although all, we believe, have now recovered. Active work has been done by many librarians for the Forces—some with a rather heavy loss of books. The Camps and Services Libraries movement, good as has been its limited activity, has not achieved much in the way of “libraries”. We have hopes, however. Everything is still, in most matters of the present and the future, in an undecided state—except the will to win through: that is universal and certain. The encouragement we receive from our American friends has been a heartening feature of a year of immense, and we believe hopeful, importance to men.
