Small unmanned aerial systems (sUAS) are used more regularly and widely in disaster response. Like other personnel involved in disaster response, the sUAS pilots work for long periods, experience extreme stress and fatigue. They often arrive at the disaster fatigued (due to long drives to get there). However, unlike other personnel in this domain, there is little research on the effects of fatigue on sUAS pilots. Our experiences with a series of three real-world deployments highlight the challenges (...) of conducting human factors research during disaster response and recovery. We specifically present lessons learned from having participant researchers embedded in three disasters with the sUAS pilot teams. These lessons result in a set of feasible and non-interruptive methods and metrics for conducting human factors research during field events. Preliminary results and recommended next steps are presented. (shrink)

Understanding female sexuality and mate choice is central to evolutionary scenarios of human social systems. Studies of female sexuality conducted by sex researchers in the United States since 1938 indicate that human females in general are concerned with their sexual well-being and are capable of sexual response parallel to that of males. Across cultures in general and in western societies in particular, females engage in extramarital affairs regularly, regardless of punishment by males or social disapproval. Families are usually concerned (...) with marriage arrangements only insofar as those arrangements are economically or politically advantageous, but females most often have a voice in arranged marriages. Extended families also concentrate on a couple’s future reproduction rather than on sexual exclusivity. Although marriage for females is often compromised by male or family reproductive interests (which may not in fact differ from female interests), females appear to exercise their sexuality with more freedom than has previously been suggested. Notions of human females as pawns in the male reproductive game, or as traders of sex for male services, should be dispelled. (shrink)

As inpatient nurses spend the majority of their work time caring for patients at the bedside, they are often firsthand witnesses to the devastating outcomes of inadequate preventive healthcare and structural injustices within current social systems. This experience should obligate inpatient nurses to be involved in meeting the social justice needs of their patients. Many nursing codes of ethics mandate some degree of involvement in the social justice needs of society, though how this is to be achieved is not (...) detailed in these general guidelines. Acknowledging an explicit obligation for inpatient nurses to address the social justice issues of their patients would facilitate better overall understanding of social justice issues and reduce preventable admissions. If implementation of such an obligation is done with care, having inpatient nurses participate in justice projects could also mitigate compassion fatigue, allow for better job satisfaction among these nurses, and provide a sense of revitalization in nurses’ role as health promoters.

Why do children learn language more easily than adults do? This puzzle has fascinated cognitive and language scientists for decades. In the present letter, we approach the language learning puzzle from a cognitive perspective that is inspired by evidence from the perceptual and motor learning literature. Neuroscientific studies show that two memory systems in the brain are involved in human learning: an early implicit procedural memory system and a late-developing cognitive or declarative memory system. We argue that higher cognitive (...) development constrains implicit statistical learning processes that are essential for learning patterns and regularities in languages, that is, the adult cognitive architecture has a cost. This is supported by experimental evidence showing that acquisition of implicit linguistic knowledge is enhanced under cognitive depletion in adults. More research is needed to test the cognitive cost hypothesis as it could partly solve the language learning puzzle. (shrink)

This work presents a system to detect small boats to help tackle the problem of this type of perilous immigration. The proposal makes extensive use of emerging technologies like Unmanned Aerial Vehicles combined with a top-performing algorithm from the field of artificial intelligence known as Deep Learning through Convolutional Neural Networks. The use of this algorithm improves current detection systems based on image processing through the application of filters thanks to the fact that the network learns to (...) distinguish the aforementioned objects through patterns without depending on where they are located. The main result of the proposal has been a classifier that works in real time, allowing the detection of pateras and people, kilometres away from the coast. This could be very useful for Search and Rescue teams in order to plan a rescue before an emergency occurs. Given the high sensitivity of the managed information, the proposed system includes cryptographic protocols to protect the security of communications. (shrink)

An approach to ethical coursework in business schools which draws upon Schon''s concept of the reflective practitioner is described. It is argued that an approach which promotes reflective practice guards against the dualism in models of ethical decision making which oppose philosophical and psychological perspectives. Workshop activities which can be used to facilitate students'' ability to reflect on ethical situations are discussed. In particular, the critical incident technique encourages students to analyse strategies they have used to cope with ethical dilemmas (...) in terms of their previous or contemporary experiences and value systems, and to examine these on the basis of philosophical principles.

This section is focused on some areas of concern which were identified in The Report of the Royal Commission into Commercial Activities of Government and Other Matters (1990–1992). In the Report a number of situations were examined in which some individuals acted without recourse to any ethical guidelines. Most of the people mentioned in the Report held responsible positions in either Government or the private sector, and all were very well known in the community. The Report of the Royal Commission (...) made a number of findings of serious impropriety on the part of several individuals, although there was comparatively little evidence of illegal or corrupt conduct. This section shows what happened to a governmental system in an Australian state when a number of Ministers and their advisors placed their personal or party advantage over their constitutional obligation to act in the community''s interests.Those who cannot remember the past are condemned to repeat it.

Industry groups engage in venue shifting when they seek to overturn or alter restrictive regulations imposed by one political venue through another. A critical step in this process is resolving uncertainties surrounding the preference of the targeted venue and the nature of the relevant policy proposal. While existing studies emphasize a long-term trial-and-error process of policy learning, we focus on nascent industries and argue that ventures seek other information sources to resolve these uncertainties quickly. In particular, nascent industry groups are (...) likely to perceive that the targeted venue will support their policy proposal if the targeted venue is ideologically distant from the venue that has enacted the restrictive regulations, if the targeted venue has recently supported other nascent industry groups’ similar policy proposals, or if the industry groups themselves are more exposed to industry peers’ success in promoting the same policy proposal in other jurisdictions. Under these conditions, the industry groups invest more to influence the targeted venue in response to restrictive regulations enacted by other venues. We find support for our theory by examining how from 2013 to 2019 the small unmanned aircraft systems industry trade associations in the United States lobbied state governments to nullify local regulations.

Postmodernism and health economics are both concerned with questions about choices and values, risk and uncertainty. Postmodernists seek to respond to such questions in the context of a world of uncoordinated and often contradictory chances, a world devoid of clear-cut standards. Health economics seeks to respond using the constructs of modernity, including the application of reason to generate better order. In this article we present two sorts of voice. First we introduce postmodernism and those seeking to contribute to economics from (...) a postmodern perspective. Second, we consider critics of a prevalent neo-classicism within health economics both from outside that paradigm and from those more closely associated with it. It is increasingly evident that (health) economics, as presently constituted, is failing both in its descriptive powers and its prescriptive possibilities. Postmodernism offers not just an alternative theoretical approach but the possibility of both expanding the scope of health economics and grounding it more appropriately in the everyday experience of those engaging with health systems.

The article considers the method of factor cluster analysis which allows automatically retrain the onboard recognition system of an unmanned aerial system. The task of informational synthesis of an on-board system for identifying frames is solved within the information-extreme intellectual technology of data analysis, based on maxi- mizing the informational ability of the system during machine learning. Based on the functional approach to modeling cognitive processes inherent to humans during forming and making classification decisions, it was proposed a categorical (...) model in the form of a direct graph. According to this model, the algorithmic support of the information extreme factor cluster analysis is developed. It allows automatically retrain the system when expanding the alphabet of recognition classes. According to this algorithm, the on-board recognition system preliminarily carries out the information-extremal machine learning of recognition classes of relatively low power. When new classes appear, their unclassified structured recognition attribute vectors form additional learning matrixes. After reaching a representational volume, additional learning matrix joins the input learning matrix and the on-board recognition system is retrained. Forming additional learning matrixes of new recognition classes is carried out by the agglomerative algorithm of cluster analysis of unclassified vectors by k-means clustering. As a criterion of optimizing machine-learning parameters, we used the modified Kullback criterion which is a functional of the exact characteristics of classification solutions. To increase the functional efficiency of factor cluster analysis, it is proposed to increase the depth of machine learning by optimizing the parameters of image processing frames. (shrink)

Over the past decade, unmanned aerial vehicles (UAVs) have received increasing attention and are being used in the areas of harvesting, videotaping, and the military industry. In this article, the consideration is focused on areas where video recording is required for ground inspections. This paper describes modern communication technologies and systems that enable interaction and data exchange between UAVs and a ground control station (GCS). This article focuses on different architectures of communication systems, establishing the characteristics of (...) each to identify the preferred architecture that does not require a significant consumption of resources and whose data transmission is reliable. A coherent architecture that includes multiple UAVs, wireless sensor networks, cellular networks, GCSs, and satellite network to duplicate communications for enhanced system security has been offered. Some reliability problems have been discussed, the solution of which was suggested to be a backup connection via satellite, i.e., a second connection. This study focused not only on the communication channels but also on the data exchanged between system components, indicating the purpose of their application. Some of the communication problems and shortcomings of various systems, as well as further focus areas and improvement recommendations were discussed. (shrink)

I argue that the human mind includes an innate domain-specific system for representing precise small numerical quantities. This theory contrasts with object-tracking theories and with domain-general theories that only make use of mental models. I argue that there is a good amount of evidence for innate representations of small numerical quantities and that such a domain-specific system has explanatory advantages when infants’ poor working memory is taken into account. I also show that the mental models approach requires previously (...) unnoticed domain-specific structure and consequently that there is no domain-general alternative to an innate domain-specific small number system.

ABSTRACTTwo categories of ethical questions surrounding military autonomous systems are discussed in this article. The first category concerns ethical issues regarding the use of military autonomous systems in the air and in the water. These issues are systematized with the Laws of Armed Conflict as a backdrop. The second category concerns whether autonomous systems may affect the ethical interpretation of LOAC. It is argued that some terms in LOAC are vague and can be interpreted differently depending on (...) which ethical normative theory is used, which may increase with autonomous systems. The impact of Unmanned Aerial Vehicles on the laws of war will be discussed and compared to Maritime Autonomous Systems. The conclusion is that there is need for revisions of LOAC regarding autonomous systems, and that the greatest ethically relevant difference between UAVs and MAS has to do with issues connected to jus ad bellum – particularly lowering the threshold for starting war – but also the sen...

Floods are one of the main natural disasters, which cause huge damage to property, infrastructure, and economic losses every year. There is a need to develop an approach that could instantly detect flooded extent. Satellite remote sensing has been useful in emergency responses; however, with significant weakness due to long revisit period and unavailability during rainy/cloudy weather conditions. In recent years, unmanned aerial vehicle systems have been widely used, especially in the fields of disaster monitoring and complex environments. (...) This study employs deep learning models to develop an automated detection of flooded buildings with UAV aerial images. The method was explored in a case study for the Kangshan levee of Poyang Lake. Experimental results show that the inundation for the focal buildings and vegetation can be detected from the images with 88% and 85% accuracy, respectively. And further, we can estimate the buildings’ inundation area according to the UAV images and flight parameters. The result of this study shows promising value of the accuracy and timely visualization of the spatial distribution of inundation at the object level for the end users from flood emergency response sector.

For unmanned aerial vehicle, object detection at different scales is an important component for the visual recognition. Recent advances in convolutional neural networks have demonstrated that attention mechanism remarkably enhances multiscale representation of CNNs. However, most existing multiscale feature representation methods simply employ several attention blocks in the attention mechanism to adaptively recalibrate the feature response, which overlooks the context information at a multiscale level. To solve this problem, a multiscale feature filtering network is proposed in this paper for (...) image recognition system in the UAV. A novel building block, namely, multiscale feature filtering module, is proposed for ResNet-like backbones and it allows feature-selective learning for multiscale context information across multiparallel branches. These branches employ multiple atrous convolutions at different scales, respectively, and further adaptively generate channel-wise feature responses by emphasizing channel-wise dependencies. Experimental results on CIFAR100 and Tiny ImageNet datasets reflect that the MFFNet achieves very competitive results in comparison with previous baseline models. Further ablation experiments verify that the MFFNet can achieve consistent performance gains in image classification and object detection tasks. (shrink)

Several robotic automation systems, such as unmanned aerial vehicles (UAVs), are being used in combat today. This evokes ethical questions. In this paper, it is argued that UAVs, more than any other weapon, may determine which normative theory the interpretation of the laws of war (LOW) will be based on. UAVs have advantages in terms of reducing casualties for the UAV possessor, but they may at the same time make war seem more like a risk-free enterprise, much like (...) a computer game, lowering the threshold for starting a war. This indicates the importance of revising the LOW, or adding some rules that focus specifically on UAVs. (shrink)

A variety of ethical objections have been raised against the military employment of uninhabited aerial vehicles (UAVs, drones). Some of these objections are technological concerns over UAVs abilities’ to function on par with their inhabited counterparts. This paper sets such concerns aside and instead focuses on supposed objections to the use of UAVs in principle. I examine several such objections currently on offer and show them all to be wanting. Indeed, I argue that we have a duty to protect (...) an agent engaged in a justified act from harm to the greatest extent possible, so long as that protection does not interfere with the agent's ability to act justly. UAVs afford precisely such protection. Therefore, we are obligated to employ UAV weapon systems if it can be shown that their use does not significantly reduce a warfighter's operational capability. Of course, if a given military action is unjustified to begin with, then carrying out that act via UAVs is wrong, just as it would be with any weapon. But the point of this paper is to show that there is nothing wrong in principle with using a UAV and that, other things being equal, using such technology is, in fact, obligatory. (shrink)

Unmanned (or Uninhabited) Aerial Vehicles are a key part of the American military's so-called revolution in military affairs (RMA) as practiced over Iraq. They are also part of the drive to shift agency away from humans and toward machines. This article considers the ways in which humans have, in calling on high technologies to distance them from what the military calls the “dull, the dirty, and the dangerous,” hoped to avoid responsibility for murder in wartime. In examining the claims (...) of weapons manufacturers and their military customers, the article focuses on the concept of “systems of systems” and the various outcomes such battlespace imaginings might have for human beings. The article concludes that the RMA entertains a fantasy of human agency while technological systems call out to and conjure up other technological systems that are possessed not only of their own logics but also purposes that are hidden and disturbing.

In lieu of an abstract, here is a brief excerpt of the content:Aviation and the Aerial View:Le Corbusier's Spatial Transformations in the 1930s and 1940sM. Christine Boyer (bio)Part One: The Aerial ViewAviation and Equipment. A London publishing house, The Studio, Ltd, sent Le Corbusier a letter in January 1935, inquiring whether he would be interested in collaborating on a new series of books to be titled The New Vision. The promoters explained that each book in the series would (...) be devoted to a unique event in industrial design, with specific attention paid to the designers, their aims, and the potential these designs held for social and human development. They would begin the series with a volume on the airplane. Le Corbusier was asked to write an introductory essay, supply captions for the images they had already collected, and offer a few suggestions for additional illustrations.1Accepting the invitation, Le Corbusier in his reply, however, transformed the project: instead of the word "airplane" he preferred "aviation," by which he meant all the prodigious phenomena opening vast new horizons in space and influencing the future of "equipment" in the broadest sense of the word.2 Already in Precisions (1930) he had written, "I replace the word 'urbanism' by the term 'equipment.' I have already replaced the term 'furniture' by that of 'equipment.' Such stubbornness shows well that we are purely and simply claiming tools for work, for we do not want to die of hunger facing the embroidered flowerbeds of aesthetic urbanism" [143]. To his bag of equipment, Le Corbusier now adds "aviation," a tool of modern communication forging new modes of exchange and new links between nations.3The material subsequently sent by the publishing house to Le Corbusier also met with lukewarm reception: he favored more lively documentation such as the view from an airplane as it flew over cities—vast open terrain, the sea, and the forests. And he wanted more picturesque treatment of the lives of aviators, their psychological and social attitudes including analysis of the great aerial routes being drawn between Europe and America, Africa, or Asia. The publishing house was unable to fulfill Le Corbusier's [End Page 93] expectations, reminding him that their focus was limited to "the airplane" and that they expected to receive all his material by May.4What did Le Corbusier mean by "aviation" and the "epic of the air," a phrase he used in the preface of the subsequent book Aircraft (1935)? What new horizons did aviation open and how did this affect the perception of space and the process of reading the terrain as a two-dimensional map or a plan? And what did aviation have to do with "equipment"? Just the year before Le Corbusier had seen the Exposition de l'Aéronautique in Milan for which Mussolini offered the maxim: "Aviation is grand, small, or nothing at all, depending on whether public awareness of aviation is grand, small, or nothing at all."5 Le Corbusier, ever the great publicist, accepted the challenge to spread the meaning of "aviation" in the inclusive sense of the word entailing adventure and service, organization, and machinery.The rapid growth of aviation during the interwar period was mercurial, dramatically reshaping perception of the world and of space. There were daring flights of aviators challenging the breath of oceans and deserts, the heights of Everest, the length of Africa, the uncharted terrain of the North and South Poles. The airplane not only internationalized cartography; it was a tool for exploring and controlling the colonies. While aerial photography, which recorded in precise detail the realistic shape of landmasses, coastlines, seas, deserts, and mountains, perfected the process of mapmaking and enriched the documentary archive of the planet.Yet even more stunning, aviation continually shrunk the size of the globe after the initial KLM flight between Amsterdam and Jakarta took off in 1924. Then the time needed to navigate the 9000 miles was 55 days; within five years it had been reduced to a mere 12 days. A world map criss-crossed with national air routes came into view. In the 1930s civil airlines began to offer passenger and mail service between London and the Middle East, then on to India and... (shrink)

Drama, at least according to the Aristotelian view, is effective inasmuch as it successfully mirrors real aspects of human behavior. This leads to the hypothesis that successful dramas will portray fictional social networks that have the same properties as those typical of human beings across ages and cultures. We outline a methodology for investigating this hypothesis and use it to examine ten of Shakespeare’s plays. The cliques and groups portrayed in the plays correspond closely to those which have been observed (...) in spontaneous human interaction, including in hunter-gatherer societies, and the networks of the plays exhibit “small world” properties of the type which have been observed in many human-made and natural systems.

Conclusions: The expert system is easy for farmers and people have experience in the plant of castor to detect and diagnosis the symptoms that may face this plant from several disease. (shrink)

In industries populated by small and medium enterprises, managers' good intentions frequently incur barriers to superior environmental performance (Tilley, Bus Strategy Environ 8:238-248, 1999). During the period when the U.S. wine industry was beginning to promote voluntary adoption of sound environmental practices, we examined managers' attitudes, norms, and perceptions of stakeholder pressures to assess their intentions to implement environmental management programs (EMP). We found that managers within the simple structures of these small and medium firms are responsive to (...) attitudes, norms, and pressures from internal stakeholders and that voluntarily established EMP increased the success of firms' implementation of energy conservation and recycling practices. Applications of our findings to future research on small and medium enterprises as well as direct practical applications of our results are discussed. (shrink)

Despite increasing attention to the sensors, drones, robots, and apps permeating agri-food systems, little attention has been paid to social media, perhaps the most ubiquitous digital technology in rural areas globally.

More broadly, my analysis builds on insights from STS and postcolonial computing to disrupt assumptions about the totalizing power of digital technologies and affirm the relevance of social media to agriculture, while inviting new research into the surprising, ambiguous relationships between small farmers and big tech.

Regional and local value creation is seen as one solution for reducing the environmental impact of the agri‐food system. The point of reference for this research is the powerless position of small actors in agri‐food chains. This paper gives insights into the motivation of small‐scale producers in developed countries to exit national and export markets and to opt for a sustainability orientation. Specifically, we explore how the powerlessness of small actors in global value chains may fuel the (...) formation of regional and local value chains. Through a regional case study, we map the dairy value system and identify three different value chain structures in the Northern German dairy industry. Then, we illustrate how some small (organic) raw milk producers have changed their position in the value chain and bargaining strength by following different upgrading strategies. Their increase in bargaining power comes with efficiency losses and increased risk. Implications for small‐scale producers and society are discussed and brought together in a framework that demonstrates the drivers and challenges for sustainability‐oriented small‐scale agricultural producers to achieve a stable and competitive position within the market.

The aerial manipulator is a complex system with high coupling and instability. The motion of the robotic arm will affect the self-stabilizing accuracy of the unmanned aerial vehicles.

By blurring the attitude error signal of UAV as the input of the neural network, the anti-interference ability and stability of UAV is improved. At (...) the same time, a neural network model identifier based on Maxout activation function is built to realize accurate recognition of the controlled model.

This empirical research provides an insight into the management of small talk and its interconnection with interpersonal relations in business negotiations, drawing on the study of its pragmatic allocation, modes and functions in business contexts.

The findings yield that ST constructs an integral, and (...) even essential, part of business communication for various social and professional purposes. Its allocations, topic typologies and move systems in negotiations are not randomly positioned, selected and developed, but strategically organized and interpersonally related. As a meaningful, politic and intentional activity, ST reflects business people’s social and professional cognition, relational negotiation and interactive frame, forming communicative primitives that are used in the underlying negotiation, the rapport management in negotiation and cultural disciplines for business people.

Tree branches near the electric power transmission lines are of great threat to the electricity supply. Nowadays, the tasks of clearing threatening tree branches are still mostly operated by hand and simple tools. Traditional structures of the multirotor aerial robot have the problem of fixed structure and limited performance, which affects the stability and efficiency of pruning operation. In this article, in order to obtain better environmental adaptability, an active deformable trees-pruning aerial robot is presented. The deformation of (...) the aerial robot is implemented through two ways, arm telescopic and folding. In order to suppress the influence of internal and external disturbances on the system, Active Disturbance Rejection Control technology is adopted to build the flight controller. Firstly, active deformation aerial robot structure is given, followed by system dynamic model establishment under wind disturbance using the Newton–Euler method. Also, the analysis of the gusts influence on the system is considered. Then, the active deformation aerial robot system is decoupled into a combination of six SISO systems, so that a disturbance rejection controller is designed. Finally, the expanded state observer and the nonlinear state error feedback law are used to inspect and compensate the disturbance. Simulation results of attitude and position tracking as well as the antidisturbance capability show that the active deformation aerial robot with the ADRC flight controller designed in this paper has excellent attitude control capabilities during flight and trees-pruning operation.

The quality of service of a user in user-centric unmanned aerial vehicle group is degraded by complex cochannel interference; hence, a cooperative game power control algorithm in UUAVG is proposed. The algorithm helps to establish a downlink power control model of the UUAVG, construct a product of the signal to interference noise ratio function of each user as a utility function of the cooperative game, and deduce the optimal power control scheme using the Lagrange function. This scheme reduces the (...) interference of the service unmanned aerial vehicle to edge users and improves the communication quality of all the users as well as the throughput of the entire system. Simulation results show that the average throughput of the CGPC algorithm improved by 10.32% compared with the traditional Stackelberg Game based Nonunified Pricing Power Control algorithm. This shows that the CGPC algorithm can effectively reduce the transmission power of the cooperative UAV and enhance the capacity of the entire system, ensuring communication quality. (shrink)

In recent years, many Small Island Developing State governments have worked to increase openness and transparency of their transactions as a means to enhance efficiency and reduce corruption in their economies.

“Small” large cardinal notions in the language of ZFC are those large cardinal notions that are consistent with V = L. Besides their original formulation in classical set theory, we have a variety of analogue notions in systems of admissible set theory, admissible recursion theory, constructive set theory, constructive type theory, explicit mathematics and recursive ordinal notations (as used in proof theory). On the face of it, it is surprising that such distinctively set-theoretical notions have analogues in such (...) disaparate and relatively constructive contexts. There must be an underlying reason why that is possible (and, incidentally, why “large” large cardinal notions have not led to comparable analogues). My long term aim is to develop a common language in which such notions can be expressed and can be interpreted both in their original classical form and in their analogue form in each of these special constructive and semi-constructive cases. This is a program in progress. What is done here, to begin with, is to show how that can be done to a considerable extent in the settings of classical and admissible set theory (and thence, admissible recursion theory). The approach taken here is to expand the language of set theory to allow us to talk about (possibly partial) operations applicable both to sets and to operations and to formulate the large cardinal notions in question in terms of operational closure conditions; at the same time only minimal existence axioms are posited for sets. The resulting system, called Operational Set Theory, is a partial adaptation to the set-theoretical framework of the explicit mathematics framework Feferman (1975). The.. (shrink)

Tradition wireless sensor networks transmit data by single or multiple hops. However, some sensor nodes close to a static base station forward data more frequently than others, which results in the problem of energy holes and makes networks fragile. One promising solution is to use a mobile node as a mobile sink, which is especially useful in energy-constrained networks. In these applications, the tour planning of MS is a key to guarantee the network performance. In this paper, a novel strategy (...) is proposed to reduce the latency of mobile data gathering in a WSN while the routing strategies and tour planning of MS are jointly optimized. First, the issue of network coverage is discussed before the appropriate number of clusters being calculated. A dynamic clustering scheme is then developed where a virtual cluster center is defined as the MS sojourn for data collection. Afterwards, a tour planning of MS based on prediction is proposed subject to minimizing the traveling distance to collect data. The proposed method is simulated in a MATLAB platform to show the overall performance of the developed system. Furthermore, the physical tests on a test rig are also carried out where a small WSN based on an unmanned aerial vehicle is developed in our laboratory. The test results validate the feasibility and effectiveness of the method proposed. (shrink)

The primate brain is able to guide complex decisions that can rapidly be adapted to changing constraints. Unfortunately, the vast numbers of highly interconnected neurons that seem to be needed make it difficult to study the cellular mechanisms that underlie the flexible combination of stored and acute information during a decision. Established simpler networks, particularly with few and identified neurons, would lend themselves more readily to such a dissection. But can simple networks implement complex and flexible decisions similarly? After a (...) brief overview of complex decisions in primates and of decision‐making in simple networks, I argue that simpler systems can combine complexity with accessibility at the cellular level. Indeed, examination of a network in fish may help in dissecting key mechanisms of complex and flexible decision‐making in an established model of synaptic plasticity at the level of identified neurons.

Forty years’ experience as a bacterial geneticist has taught me that bacteria possess many cognitive, computational and evolutionary capabilities unimaginable in the first six decades of the twentieth century. Analysis of cellular processes such as metabolism, regulation of protein synthesis, and DNA repair established that bacteria continually monitor their external and internal environments and compute functional outputs based on information provided by their sensory apparatus. Studies of genetic recombination, lysogeny, antibiotic resistance and my own work on transposable elements revealed multiple (...) widespread bacterial systems for mobilizing and engineering DNA molecules. Examination of colony development and organization led me to appreciate how extensive multicellular collaboration is among the majority of bacterial species. Contemporary research in many laboratories on cell–cell signaling, symbiosis and pathogenesis show that bacteria utilise sophisticated mechanisms for intercellular communication and even have the ability to commandeer the basic cell biology of ‘higher’ plants and animals to meet their own needs. This remarkable series of observations requires us to revise basic ideas about biological information processing and recognise that even the smallest cells are sentient beings.

Unification of natural science and social science is a centuries-old, unmitigated debate. Natural science has a chronological advantage over social science because the latter took time to include many social phenomena in its fold. History of science witnessed quite a number of efforts by social scientists to fit this discipline in a rational if not mathematical framework. On the other hand a tendency among some physicists has been observed especially since the last century to recast a number of social phenomena (...) in the mould of events taking place in physical world and governed by well-known systems and equations of physics. It necessitated the introduction of social physics as a new inter-disciplinary subject. Obviously this attempt is aimed at explaining hitherto unsolved or highly debated issues of social science. Physicists are showing special interest on problems on economics, ranging from some topics of normative economics to the movement of prices of derivatives. Statistics has been widely used in these attempts and at least two sub-disciplines of the subject, namely, stochastic process and time series analysis deserve special mention. All these research activities gave birth to another inter-disciplinary subject named as econophysics. Interestingly, global financial crisis of 2007–08 has revived the need of determination of prices of derivatives in a more accurate manner. This article adumbrates a sketch of the theoretical synthesis between physics and economics and the role played by statistics in this process. (shrink)

This article is concerned with how to conceptualize and theorize the nature of the ‘car system’ that is a particularly key, if surprisingly neglected, element in ‘globalization’. The article deploys the notion of systems as self-reproducing or autopoietic. This notion is used to understand the origins of the 20th-century car system and especially how its awesome pattern of path dependency was established and exerted a particularly powerful and self-expanding pattern of domination across the globe. The article further considers whether (...) and how the 20th-century car system may be transcended. It elaborates a number of small changes that are now occurring in various test sites, factories, ITC sites, cities and societies. The article briefly considers whether these small changes may in their contingent ordering end this current car system. The article assesses whether such a new system could emerge well before the end of this century, whether in other words some small changes now may produce the very large effect of a new post-car system that would have great implications for urban life, for mobility and for limiting projected climate change.
