Contemporary scientific research and public policy are not in agreement over what should be done to address the dangers that result from the drop in driving performance that occurs as a driver talks on a cellular phone. One response to this threat to traffic safety has been the banning in a number of countries and some states in the USA of handheld cell phone use while driving. However, research shows that the use of hands-free phones (such as (...) headsets and dashboard-mounted speakers) also accompanies a drop, leading some to recommend regulation of both kinds of mobile phones. In what follows, I draw out the accounts of the driving impairment associated with phone use implicit in research and policy and develop an alternative account grounded in philosophical considerations. Building on work in a school of thought called postphenomenology, I review and expand concepts useful for articulating human bodily and perceptual relations to technology. By applying these ideas to the case of driving while talking on the phone, I offer an account of the drop in driving performance which focuses on the embodied relationships users develop with the car and the phone, and I consider implications for research and policy.

Cellular, or mobile phones are great: they allow people to communicate over long distances whenever and wherever they are, and instantaneously at that when the one called is wearing one too. Having said that, though, it must immediately be added that they, also, have a complex disadvantage, and it is one we are hard pushed to understand. In fact, due to its complexity people simply tend to neglect it, even though everyone in his right mind has had experience with (...) it. Now Walter Benjamin defined aura as “a distance however close it may be”.1) This has standardly been interpreted as a characterisation of an experience of presence, also by Benjamin. This aura supposedly suffered from the rise of photography. Aura can, also, be understood as inertia, the absence of something present. And whether aura is gone or widespread I gladly leave to more speculative-minded thinkers. I submit that we experience a person’s “aura”—her distance however close she may be—when perception tells us the person is present yet our mind realises that she isn’t. I am referring here to the observation had of another person engaged in a cell phone conversation. The inertia of the cell phone caller consists in her incapacity to address those who observe her. I think there is an immoral streak to her selfappointed moral autonomy. In a previous edition of this Dutch-Russian exchange on inertia I argued that our trafficking with facial expressions forms the model with which we’d best understand the workings of art—facial expression is the anthropological foundation of art. My discussion, today, of the cell phone conversation is meant to add to that previous suggestion. (shrink)

The article proposes to model the phenomenon of the cell phone as a wall-window. This model aims at explicating some of the perceptions and experiences associated with cellular technology. The wall-window model means that the cell phone simultaneously separates the user from the physical surroundings (the wall), and connects the user to a remote space (the window). The remote space may be where the interlocutor resides or where information is stored (e.g. the Internet). Most cell phone (...) usage patterns are modeled as a single dimension according to the level of distraction or attention of the user. In order to accommodate nuanced situations such as augmented reality, I suggest a two-dimensional layout: the wall-window. The wall represents the attention to the immediate physical environment, while the window represents the attention to a remote space. The wall-window model further evolves once a screen is woven into this layout. This addition is easily understood due to the screen’s etymology, which is associated with the concepts of shield or barrier. From a technical perspective, the screen has become an integral part of the cell phone. Furthermore, a screen itself is both a wall and a window. Lastly, once a cell phone is supplemented with a screen, it is easier to refer to it as media. And again, media fits into the wall-window model. (shrink)

Perception and reciprocity are key understandings in the lived experience of driving while using a cellular phone. When I talk on a cell phone while driving, I interpret the world through a variety of technologically mediated perceptions. I interpret the bumps in the road and the bug on the windshield. I perceive the information on the dashboard and the conversation with the Other on the other end of the technological “line” of the phone. This reflection uses (...) hermeneutical phenomenology to address the things themselves in life with which we relate and interact with in our everydayness, as we talk on a cell phone while driving.

While cellular phones have become common among Filipinos, it is contended that, even though, such accessibility may have bridged the digital gap, it is far from eradicating social divides between the rich and the poor. The class divide is very apparent based on usage alone. This divide is more a function of income and education than the availability of technology. Three aims of this study include: 1) finding out whether social stratification is evident in the text messages of people (...) from lower, middle, and upper classes; 2) affirming the relationship between social stratification and linguistic forms usage; and 3) exploring noticeable patterns in texting styles of participants. Employing mixed methods design, linguistic forms used by participants were described and analyzed. Noticeable patterns in the texting styles of 18 participants were also accounted. Three linguistic forms: shortenings, punctuations, and letters/numbers/homophones are frequently used by the participants across the three social classes to facilitate ease of texting and to shorten long words. Two form categories are socially stratified: punctuations and accent stylization. Thus, knowing the linguistic forms used by an individual can lead to knowledge of his/her social status. Keywords- Sociolinguistics, Computer-mediated Communication, social stratification, linguistic forms, textual analysis, mixed methods design, Philippines. (shrink)

Technological advances in the information and knowledge society have influenced and transformed economic, social and educational dynamics. Currently there are many digital gaps related to the access to technology, lack of digital literacy and social use. These gaps vary based on the population ages and become more notorious in elders. This digital illiteracy is making all technological developments of the XXI Century to be underused, not making possible to take advantage of all the possibilities that they offer to our society, (...) in this case, to Colombia. This study aims at analyzing the penetration level and use of handheld digital devices, especially the cellular phone, in adult population, based on the 2016 national survey of life quality in Colombia, elaborated by Departamento Administrativo Nacional de Estadística-DANE, specifically on the module of ownership and use of ICT goods. Results of four age groups are compared: 32 years or under, from 33 to 45, from 46 to 59, and over 60. The total sample is 37047 inhabitants of the Colombian territory, grouped by regions (Antioquia, Bogota, Caribbean, Eastern Central, Orinoquia, Amazonia, Pacific, San Andres, and Valle del Cauca). Data have been analyzed by using descriptive and inferential statistical procedures, contingency tables analysis, and logistic regression, in order to identify and know the effect of age on the level of penetration and use of handheld digital devices when comparing results in young adults and older ones. Findings show that young adults use these technologies in a greater proportion when comparing to older adults, showing a significant correlation between age and the increase of the digital gaps of access and social use of handheld digital devices. Even when characteristics like country regions, level of education, and the urban or rural setting are taking into account, the probability of obtaining penetration and use of handheld digital devices decreases significantly when attaining old age.

In the past decade, digital technology, fiber optics, cellular phones, satellite television, home computers, and the Internet have substantially transformed business, education, and leisure practices. These technologies are becoming so integrated into our daily routines that their ubiquity often goes unnoticed. We are, nonetheless, in the midst of a telecommunications revolution, and the healthcare industry is becoming a major player. The burgeoning field of home-based telemedicine is evidence of this.

In this essay, I first analyze the extension of hermeneutical interpretation in the Heideggerian sense to products of contemporary technology which are components of our “lifeworld”. Products of technology, such as airplanes, laptops, cellular phones, washing machines, or vacuum cleaners might be compared with what Heidegger calls the “Ready-to-hand” (das Zuhandene) with regard to utilitarian objects such as a hammer, planer, needle and door handle in Being and Time. Our life with our equipment, which represents the “Ready-to-hand” in Heidegger's (...) sense of the word, is determined by temporalization (Zeitigung) which cannot be separated and isolated from the wholeness of things in the world. In the second part of my paper, I explore the positive achievement of material hermeneutics (Don Ihde) with regard to its extension to technoscience and the discussion of how such hermeneutics can contribute to the preservation of our threatened lifeworld, but also to explore the possibilities of how technical inventions, medical innovations could improve our way of life.

This paper deals with how telematic technologies such as the cellular phones, Internet, telerobotics and other varieties of telematic communication and control are placing into discussion the nature of knowledge and its scope. These technologies offer us knowledge by description and representation instead of physical contact, a fact that is often seen with suspicion since they are perceived as technologies of delusion in a culture characterized by its conspicuous materialism. What are the possible roles for our mediated activities in (...) relation with the comprehension of our environment and the construction of subjectivity? Telematic mediation necessarily deals with the immaterial aspects of technologies such as the changing concepts of reality and nature, future possibilities of an ethereal afterlife achieved through spiritual or technological means and the concept of distance that can render mediated communication delusory and unsatisfying while acting as an agent of delocalization. This view is supported by our traditional Platonic view that perceives representation of things as a palpable degradation while neglecting the constructive aspects of those fictional endeavours.

According to the widespread use of Web Services, composition of multiple services is becoming a main issue. BPEL was proposed as a Web Services workflow language in this context. Then, in many cases we need much interactions between a service requester and a BPEL process execution engine. However for the end user under the ubiquitous environment where the service is executed with a cellular phone or PDA, the interaction means simply a burden. The reason is: (1)it is hard (...) to carry out the operation manually, (2)a network connection is unstable, (3)a connection charge is relatively high. In this paper, we propose middle agents between ubiquitous users and Web Services. The agents analyze BPEL, extract the interaction which the ubiquitous users would need, then produce action operators. It makes a plan in order to achieve a service request from the user. Here the planning agent can reduce operations of the user by collecting the necessary information at the beginning which will be inputted during the IP execution. We show the architecture of the agents and an example regarding ATM service, then evaluate the number of inputs, the performance, and the quantity of data transmitted on network. Finally, we consider adaptability of this approach to generic BPEL flow. (shrink)

Recently, agent technologies have attracted a lot of interest as an emerging programming paradigm. With such agent technologies, services are provided through collaboration among agents. At the same time, the spread of mobile technologies and communication infrastructures has made it possible to access the network anytime and from anywhere. Using agents and mobile technologies to realize ubiquitous computing systems, we propose a new framework based on KODAMA and VPC. KODAMA provides distributed management mechanisms by using the concept of community and (...) communication infrastructure to deliver messages among agents without agents being aware of the physical network. VPC provides a method of defining peer-to-peer services based on agent communication with policy packages. By merging the characteristics of both KODAMA and VPC functions, we propose a new framework for ubiquitous computing environments. It provides distributed management functions according to the concept of agent communities, agent communications which are abstracted from the physical environment, and agent collaboration with policy packages. Using our new framework, we conducted a large-scale experiment in shopping malls in Nagoya, which sent advertisement e-mails to users' cellular phones according to user location and attributes. The empirical results showed that our new framework worked effectively for sales in shopping malls. (shrink)

Telecommunications services are for long subject to privacy regulations. At stake are traditionally: privacy of the communication and the protection of traffic data. Privacy of the communication is legally founded. Traffic data subsume under the notion of data protection and are central in the discussion. The telecommunications environment is profoundly changing. The traditionally closed markets with closed networks change into an open market with open networks. Within these open networks more privacy sensitive data are generated and have to be exchanged (...) between growing numbers of parties. Also telecommunications and computer networks are rapidly being integrated and thus the distinction between telephony and computing disappears. Traditional telecommunications privacy regulations are revised to cover internet applications. In this paper telecommunications issues are recalled to aid the on-going debate. Cellular mobile phones have recently be introduced. Cellular networks process a particular category of traffic data namely location data, thereby introducing the issue of territorial privacy into the telecommunications domain. Location data are bound to be used for pervasive future services. Designs for future services are discussed and evaluated for their impact on privacy protection. (shrink)

The practice of sending and receiving sexually explicit images via mobile phones has grown exponentially in recent years with the accessibility of cellular technology. This essay examines this practice, when conducted by teenagers, in light of a Christian feminist approach to justice. Without harmfully exhorting girls' sexual "purity", we must nevertheless develop a moral framework that challenges the practice of sexting while simultaneously empowering young women to claim primary control over their own sexual experience. For Christians, justice, addressed to (...) sexting, must attend to sexual injustice even as it promotes genuine freedom, embodiment, mutuality and relational intimacy, and equality. (shrink)

The need for services in the world of telecommunications and the prosperity and rapid development of this sector around the world has led mobile phone companies to compete to provide the best services to customers. One of these devices used for communications is the mobile phone. The mobile phone is simply an electronic device that is mainly serving unwired telecommunications through a cellular network of particular base stations known as cell sites. There are many obstacles or (...) problems in the telecommunication field, and the relevant institutions and companies should find solutions to these obstacles and problems. One of these obstacles in telecommunications is the coverage holes. Coverage holes occur when the location of the mobile phone is set in midway between the two base transceiver stations (BTSs). This causes an abnormal interruption in communication until the user crosses the coverage holes area. This paper presents an intelligent algorithm as a set of technical steps that can be used to improve the communication services of the mobile phone network and to solve the communication problems via the reduction of the coverage holes between two BTSs. It suggests a method that could alleviate this problem using a strategy that reduces the coverage holes by developing an intelligent algorithm system to receive signal strength indicators and use AT command “+CREG” to disconnect and reconnect to available BTS within an acceptable energy level. As a result, the connection turned from marginal into good connection. (shrink)

When a piece of fruit is in a bowl, and the bowl is on a table, we appreciate not only the individual objects and their features, but also the relations containment and support, which abstract away from the particular objects involved. Independent representation of roles (e.g., containers vs. supporters) and “fillers” of those roles (e.g., bowls vs. cups, tables vs. chairs) is a core principle of language and higherlevel reasoning. But does such role-filler independence also arise in automatic visual processing? (...) Here, we show that it does, by exploring a surprising error that such independence can produce. In four experiments, participants saw a stream of images containing different objects arranged in forcedynamic relations — e.g., a phone contained in a basket, a marker resting on a garbage can, or a knife sitting in a cup. Participants had to respond to a single target image (e.g., a phone in a basket) within a stream of distractors presented under time constraints. Surprisingly, even though participants completed this task quickly and accurately, they false-alarmed more often to images matching the target’s relational category than to those that did not — even when those images involved completely different objects. In other words, participants searching for a phone in a basket were more likely to mistakenly respond to a knife in a cup than to a marker on a garbage can. Follow-up experiments ruled out strategic responses and also controlled for various confounding image features. We suggest that visual processing represents relations abstractly, in ways that separate roles from fillers. (shrink)

In some recent papers (G. ‘t Hooft and others), it has been argued that quantum mechanics can arise from classical cellular automata. Nonetheless, G. Shpenkov has proved that the classical wave equation makes it possible to derive a periodic table of elements, which is very close to Mendeleyev’s one, and describe also other phenomena related to the structure of molecules. Hence the classical wave equation complements Schrödinger’s equation, which implies the appearance of a cellular automaton molecular model starting (...) from classical wave equation. The other studies show that the microworld is constituted as a tessellation of primary topological balls. The tessellattice becomes the origin of a submicrospic mechanics in which a quantum system is subdivided to two subsystems: the particle and its inerton cloud, which appears due to the interaction of the moving particle with oncoming cells of the tessellattice. The particle and its inerton cloud periodically change the momentum and hence move like a wave. The new approach allows us to correlate the Klein-Gordon equation with the deformation coat that is formed in the tessellatice around the particle. The submicroscopic approach shows that the source of any type of wave movements including the Klein-Gordon, Schrödinger, and classical wave equations is hidden in the tessellattice and its basic exciations – inertons, carriers of mass and inert properies of matter. We also discuss possible correspondence with Konrad Zuse’s calculating space. (shrink)

Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, (...) following state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance). Secondly, CA are abstract, as they can be specified in purely mathematical terms and implemented in physical structures. Thirdly, CA are computational systems: they can compute functions and solve algorithmic problems. Despite functioning in a different way from traditional, Turing machine-like devices, CA with suitable rules can emulate a universal Turing machine, and therefore compute, given Turing's Thesis, anything computable....

This chapter is to offer a critical study of what the human living condition would be like in a new era of hi-tech mobilization, especially the condition of self-government or autonomy, and how, in the Thai perspective, the condition affects culture. Habermas’ analysis of individuation through socialization and Heidegger’s question concerning technology and being are used in the study, and it is revealed that we are now confronted with a new technological condition of positioned individuals in the universe of communication (...) through mobile phones. This situation surely will be realized in a world highly mobilized by the phenomenon of connectedness. This means that we are concerning ourselves with our concrete individuality for our self-expression in that universe. I offer an interpretation that we would hold this kind of individuality to be valuable because of an effect from technological thinking. In addition, comparing this view on individuality with Buddhism, I found that the view offered here is not similar to the Buddhist concept of self as a construction. I offer an argument to show that these concepts are basically different for ethical reasons; while the Buddhist concept still preserves the nobility of the moral agent (Buddhism, after all, is a religion and needs to concern itself with morality), the concrete individuality discussed here is considered only as an instrumental value in a world of hi-tech mobilization.

Conversation analytical methodology was used to specify the new opening practices in Finnish mobile call openings, which differ systematically from Finnish landline call openings. Since the responses to a mobile call orient to the summons identifying the caller, answers have changed and diversified. A known caller is greeted. The self-identification opening that was canonical in Finnish landline calls is mainly used for answering unknown callers, while channel-opener openings involve orientation to ongoing mutual business between the speakers. Some of these changes (...) reflect real-time coordination of the social action that the mobility of mobile phones enables. In all, the adoption of new ways of answering a call shows that people orient themselves to affordances that new technologies allow them. Mobile phone communication opens a salient new area both for the analysis of talk-ininteraction itself and also for understanding communicative behaviour in the era of ubiquitous information technology.

Cells live in dynamic environments that necessitate perpetual adaptation. Since cells have limited resources to monitor external inputs, they are required to maximize the information content of perceived signals. This challenge is not unique to microscopic life: Animals use senses to perceive inputs and adequately respond. Research showed that sensory‐perception is actively shaped by learning and expectation allowing internal cognitive models to “fill in the blanks” in face of limited information. We propose that cells employ analogous strategies and use internal (...) models shaped through the long process of evolutionary adaptation. Given this perspective, we postulate that cells are prone to “misperceptions,” analogous to visual illusions, leading them to incorrectly decode patterns of inputs that lie outside of their evolutionary experience. Mapping cellular misperception can serve as a fundamental approach for dissecting regulatory networks and could be harnessed to modulate cell behavior, a potentially new avenue for therapy. (shrink)

This paper considers the implications of precautionary restrictions against technologies, in the context of the potential for creating and sustaining rumours. It focuses on the restriction against mobile phone use at petrol stations, based on the rumour that a spark might cause an explosion. Rumours have been substantiated by precautionary usage warnings from mobile phone manufacturers, petrol station usage restrictions, and a general lack of technical understanding. Petrol station employees have themselves spread the rumour about alleged incidents, filling (...) the information gap about the basis for the restriction. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

In a 1997 paper Jennifer Saul adduces various examples of simple sentences in which the substitution of one co-referential singular term for another appears to be invalid. I address the question of whether anti-substitution is logically justified by examining the validity and soundness of substitution of co-referential singular terms in three simple-sentence arguments each exhibiting a different logical structure. The result is twofold. First, all three arguments are valid, provided Leibniz’s Law is valid with respect to simple sentences . Thus, (...) as far as these arguments are concerned, there is no logical problem with substitution in simple sentences. Second, two of the arguments cannot be sound, because their respective sets of premises are inconsistent. Thus, it would be logically irrational to commit oneself to all the premises of the respective arguments. To the extent that the origin of Saul’s puzzles is in logic , I suggest, tentatively, that substitution may appear to be invalid because the issues of validity and soundness have not been kept separate. I then consider in depth Saul’s first sentence, “Clark Kent enters a phone booth and Superman exits”. Obviously, two-way substitution is trivially valid, if the expressions are co-referential semantically proper names, the conclusion being but a rephrasing of the premise. However, I argue that a non-trivial semantic analysis of this sentence should take account of the diachronicity of Clark Kent’s entrance and Superman’s exit while preserving the internal link between being Superman and being Clark Kent. I propose the following. ‘Superman’ and ‘Clark Kent’ refer to two distinct individual concepts. “Superman is Clark Kent” then no longer expresses the self-identity of an individual bearing two names, but that two named concepts are held together by the requisite relation: wherever and whenever someone falls under the concept of Superman the same individual also falls under the Clark Kent concept, whereas there are exceptions to the converse. This semantic analysis always validates the substitution of ‘Clark Kent’ for ‘Superman’, but validates the substitution of ‘Superman’ for ‘Clark Kent’ only if the additional condition is met that somebody should fall under the Superman concept when Clark Kent.

Recall that for any Boolean algebra (BA) A, the cellularity of A is c(A) = sup{|X| : X is a pairwise-disjoint subset of A}. A pseudo-tree is a partially ordered set (T, ≤) such that for every t in T, the set {r ∊ T : r ≤ t} is a linear order. The pseudo-tree algebra on T, denoted Treealg(T), is the subalgebra of ℘(T) generated by the cones {r ∊ T : r ≥ t}, for t in T. We (...) characterize the cellularity of pseudo-tree algebras in terms of cardinal functions on the underlying pseudo-trees. For T a pseudo-tree, c(Treealg(T)) is the maximum of four cardinals c\sbT, ι\sbT, φ\sbT, and μ\sbT : roughly, c\sbT measures the "tallness" of the pseudo-tree T; ι\sbT the "breadth"; φ\sbT the number of "finite branchings"; and μ\sbT the number of places where T "does not branch." We give examples to demonstrate that all four of these cardinals are needed. (shrink)

Depression might be associated with accelerated cellular aging. However, does this result in an irreversible state or is the body able to slow down or recover from such a process? Telomeres are DNA‐protein complexes that protect the ends of chromosomes and generally shorten with age; and therefore index cellular aging. The majority of studies indicate that persons with depression have shorter leukocyte telomeres than similarly aged non‐depressed persons, which may contribute to the observed unfavorable somatic health outcomes in (...) the depressed population. Some small‐scale preliminary studies raise the possibility that behavioral or pharmacological interventions may either slow down or else reverse this accelerated telomere shortening, possibly through increasing the activity of the telomere‐lengthening enzyme telomerase. This paper covers the current state of evidence in the relationship between depression and the telomere‐telomerase system and debates whether depression‐related cellular aging should be considered a reversible process or permanent damage.

Unlike eggs and diatoms, most single cells in nature do not have structured shells to provide extensive protection. It is a challenge to artificially confer shell structures on living cells to improve their inherent properties and functions. We discuss four different types of cellular shellizations: man‐made hydrogels, sol‐gels, polyelectrolytes, and mineral shells. We also explore potential applications, such as cell storage, protection, delivery, and therapy. We suggest that shellization could provide another means to regulate and functionalize cells. Specifically, the (...) integration of living cells and non‐living functional shells may be developed as a novel strategy to create “super” or intelligent cells. Unlike biological approaches, this material‐based bio‐interface regulation is inexpensive, effective, and convenient, opening up a novel avenue for cell‐based technologies and practices. (shrink)

This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft. Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory. The book presents examples of models that are classical in essence, but can be analysed by the (...) use of quantum techniques, and argues that even the Standard Model, together with gravitational interactions, might be viewed as a quantum mechanical approach to analysing a system that could be classical at its core. He shows how this approach, even though it is based on hidden variables, can be plausibly reconciled with Bell's theorem, and how the usual objections voiced against the idea of 'superdeterminism' can be overcome, at least in principle. This framework elegantly explains - and automatically cures - the problems of the wave function collapse and the measurement problem. Even the existence of an "arrow of time" can perhaps be explained in a more elegant way than usual. As well as reviewing the author's earlier work in the field, the book also contains many new observations and calculations. It provides stimulating reading for all physicists working on the foundations of quantum theory. (shrink)

This study investigated the use of mobile telephones by males and females in a public bar frequented by professional people. We found that, unlike women, men who possess mobile telephones more often publicly display them, and that these displays were related to the number of men in a social group, but not the number of women. This result was not due simply to a greater number of males who have telephones: we found an increase with male social group size in (...) the proportion of available telephones that were on display. Similarly, there was a positive relationship between the number of visible telephones and the ratio of males to females. Our results further show that the increased display of telephones in groups with more males is not due to the ostensive function of these devices (i.e., the making and receiving of calls), although single males tended to use their phones more. We interpret these results within the framework of male-male competition, with males in larger group sizes functioning in an increasingly competitive environment. This competitive environment is suggested to be akin to a lek mating system in which males aggregate and actively display their qualities to females who assess males on a number of dimensions. We suggest that mobile telephones might be used by males as an indicator of their status and wealth (sensu “cultural ornaments”). (shrink)

Purpose There is a contradictive debate on factors influencing mobile phone usage awareness among scholars. This study aims to examine factors influencing mobile phone usage awareness for accessing agricultural marketing information. Design/methodology/approach A descriptive cross-sectional research design was used with 400 smallholder grape farmers. The use of structured questionnaires, focus group discussions and key informant interviews helped to collect primary data. Data analysis was subjected to descriptive, ordinal logistic regression and thematic approaches. Findings This study found that farmers (...) were mostly aware of voice calls helping to access buyers and price information. Education, age and sex were the critical factors influencing mobile phone usage awareness among grape smallholder farmers. Originality/value This study contributes to scientific knowledge by providing an understanding of the perceived factors on mobile phone usage awareness within the grape subsector to inform policymakers.

We exhibit a bridge between the theory of cellular categories, used in algebraic topology and homological algebra, and the model-theoretic notion of stable independence. Roughly speaking, we show that the combinatorial cellular categories (those where, in a precise sense, the cellular morphisms are generated by a set) are exactly those that give rise to stable independence notions. We give two applications: on the one hand, we show that the abstract elementary classes of roots of Ext studied by (...) Baldwin–Eklof–Trlifaj are stable and tame. On the other hand, we give a simpler proof (in a special case) that combinatorial categories are closed under 2-limits, a theorem of Makkai and Rosický. (shrink)

Phone is a topic that is not so much explored and examined in Plato. Given eighteen times use of this word in Protagoras, this dialogue can be the suitable place to do a research about its meanings. Here the use of phone covers different subjects and facets of this word as an umbrella word so that in order to reach an ordered and meaningful understanding we place those aspects which are analogous in specific set and title.

The target article on cellular mechanisms of long-term depression appears to have been well received by most authors of the relevant commentaries. This may be due to the fact that this review aimed to give a general account of the topic, rather than just describe previous work of the present author.

It has been known for long time that the cosmic sound wave was there since the early epoch of the Universe. Signatures of its existence are abound. However, such a sound wave model of cosmology is rarely developed fully into a complete framework. This paper can be considered as our second attempt towards such a complete description of the Universe based on soliton wave solution of cosmological KdV equation. Then we advance further this KdV equation by virtue of Cellular (...) Automaton method to solve the PDEs. We submit wholeheartedly Robert Kurucz’s hypothesis that Big Bang should be replaced with a finite cellular automaton universe with no expansion. Nonetheless, we are fully aware that our model is far from being complete, but it appears the proposed cellular automaton model of the Universe is very close in spirit to what Konrad Zuse envisaged long time ago. It is our hope that the new proposed method can be verified with observation data. But we admit that our model is still in its infancy, more researches are needed to fill all the missing details.

Ranging from miniaturized biological robots to organoids, multi-cellular engineered living systems (M-CELS) pose complex ethical and societal challenges. Some of these challenges, such as how to best distribute risks and benefits, are likely to arise in the development of any new technology. Other challenges arise specifically because of the particular characteristics of M-CELS. For example, as an engineered living system becomes increasingly complex, it may provoke societal debate about its moral considerability, perhaps necessitating protection from harm or recognition of (...) positive moral and legal rights, particularly if derived from cells of human origin. The use of emergence-based principles in M-CELS development may also create unique challenges, making the technology difficult to fully control or predict in the laboratory as well as in applied medical or environmental settings. In response to these challenges, we argue that the M-CELS community has an obligation to systematically address the ethical and societal aspects of research and to seek input from and accountability to a broad range of stakeholders and publics. As a newly developing field, M-CELS has a significant opportunity to integrate ethically responsible norms and standards into its research and development practices from the start. With the aim of seizing this opportunity, we identify two general kinds of salient ethical issues arising from M-CELS research, and then present a set of commitments to and strategies for addressing these issues. If adopted, these commitments and strategies would help define M-CELS as not only an innovative field, but also as a model for responsible research and engineering. (shrink)

This paper is an introduction into the theory of cellular spaces. From the more general model of nets of abstract cells which are interpreted by finite automata, it is shown how the model of cellular spaces is achieved by specialization. Cellular spaces are extremely homogeneous in function and in geometry. The relation between local and global behavior is regarded as the main topic of the theory. After a formal definition of cellular spaces, it is shown that (...) not all functions of the configuration space are induced by cellular spaces. In addition, the Garden-of-Eden problem is discussed, and a simple self-reproduction property is explained. (shrink)
