Ecology has become a popular conceptual model in numerous fields of inquiry and it seems especially appropriate for environmental philosophy. Apart from its literal employment in biology, ecology has served as a useful metaphor that captures the interdependence of factors in a field of research. At the same time as ecology is suggestive, it cannot be followed literally or blindly. This paper considers the appropriateness of the uses to which ecology has been put in some recent discussions of architectural and (...) environmental aesthetics, and develops a critique of the differing ecological aesthetics of Jusuck Koh and Xiangzhan Cheng.

In the progress of globalisation, the human being is exposed to effects of cultural dominance. For the individual, this exposure can be the stronger, the more autonomous his or her culture of origin used to be before the confrontation. Global consent with regard to behaviour patterns and cogni¬tive styles leads to the obliteration of traditional knowledge and behaviour upon which identity has been defined. The loss of identity in favour of belonging to the global society brings about a number of (...) problems, which can be demonstrated in functional models. These models, in turn, may sup¬port the planning of interventional strategies and rescue work. (shrink)

This paper discusses critically what simulation models of the evolution of cooperation can possibly prove by examining Axelrod’s “Evolution of Cooperation” (1984) and the modeling tradition it has inspired. Hardly any of the many simulation models in this tradition have been applicable empirically. Axelrod’s role model suggested a research design that seemingly allowed to draw general conclusions from simulation models even if the mechanisms that drive the simulation could not be identified empirically. But this research design was fundamentally flawed. At (...) best such simulations can claim to prove logical possibilities, i.e. they prove that certain phenomena are possible as the consequence of the modeling assumptions built into the simulation, but not that they are possible or can be expected to occur in reality. I suggest several requirements under which proofs of logical possibilities can nevertheless be considered useful. Sadly, most Axelrod-style simulations do not meet these requirements. It would be better not to use this kind of simulations at all. (shrink)

Simulation models of the Reiterated Prisoner's Dilemma (in the following: RPD-models) are since 30 years considered as one of the standard tools to study the evolution of cooperation (Rangoni 2013; Hoffmann 2000). A considerable number of such simulation models has been produced by scientists. Unfortunately, though, none of these models has empirically been verified and there exists no example of empirical research where any of the RPD-models has successfully been employed to a particular instance of cooperation. Surprisingly, this has not (...) kept scientists from continuing to produce simulation models in the same tradition and from writing their own history as a history of success. In a recent simulation study -- which does not make use of the RPD but otherwise follows the same pattern of research -- Robert Axelrod's (1984) original role model for this kind of simulation studies is praised as ``an extremely effective means for investigating the evolution of cooperation'' and considered as ``widely credited with invigorating that field'' (Rendell et al. 2010).

Simulation models of the Reiterated Prisoner's Dilemma have been popular for studying the evolution of cooperation since more than 30 years now. However, there have been practically no successful instances of empirical application of any of these models. At the same time this lack of empirical testing and confirmation has almost entirely been ignored by the modelers community. In this paper, I examine some of the typical narratives and standard arguments with which these models are justified by their authors despite (...) the lack of empirical validation. I find that most of the narratives and arguments are not at all compelling. None the less they seem to serve an important function in keeping the simulation business running despite its empirical shortcomings. (shrink)

This paper tries to answer the question why the epistemic value of so many social simulations is questionable. I consider the epistemic value of a social simulation as questionable if it contributes neither directly nor indirectly to the understanding of empirical reality. To examine this question, two classical social simulations are analyzed with respect to their possible epistemic justification: Schelling’s neighborhood segregation model and Axelrod’s reiterated Prisoner’s Dilemma simulations of the evolution of cooperation. It is argued that Schelling’s simulation is (...) useful because it can be related to empirical reality, while Axelrod’s simulations and those of his followers cannot and thus that their scientific value remains doubtful. I relate this findingto the background beliefs of modelers about the superiority of the modeling method as expressed in Joshua Epstein’s keynote address “Why model?”. (shrink)

Human beings define their identity primarily by the way they present, design and style their bodies. In doing so, individuals make statements about their affiliation to a social context. Globalisation implies a change of identity among the members of less industrialised cultures, as they are exposed to effects of cultural dominance. For the individual, this exposure can be the stronger, the more autonomous his or her culture of origin used to be before the confrontation. There is a bias of cultural (...) elements that are being transferred, so that the industrialised culture has a strong impact on other cultures. Global consent with regard to behaviour patterns, especially to bodily self-presentation and the related cognitive styles, leads to the obliteration of traditional knowledge, which is interwoven with the behaviour upon which identity had been defined previously. The cultural elements transferred are being used for the construction of globally standardised personal identities, whereat elements concerning the visual design of the human body are of major relevance for defining the self. The loss of variegated identities in favour of belonging to the global society brings about a number of problems, which can be demonstrated in functional models. These models, in turn, may support the planning of interventional strategies and rescue work. In this article, the role of the body within the destabilising effects of cultural change are analysed, and chances for intervention are discussed. (shrink)

In order to protect indigenous cultures, their knowledge and their ways of living, it is necessary to analyse the mechanisms of cultural change, with a special focus on those factors that lead to the destabilisation, and even deletion, of formerly autonomous social systems. -/- Cultures consist of human beings, and the mechanisms and interactions within and between cultures consist of human behaviour. Generally, the mutual influences between cultures do not occur in a symmetrical way. Rather, one side is usually exposed (...) to effects of the cultural dominance, which the other side exercises upon it. Within the macrostructure of intercultural influences, cultural elements of indigenous cultures are deleted and replaced by the cultural elements of the dominant culture. In the progress of globalisation, consent among the participants with regard to behaviour patterns and cognitive styles leads to the obliteration of traditional knowledge and behaviour which until then had been characteristic for the respective cultural group. -/- Meanwhile, indigenous cultures are endangered worldwide, and the process of globalisation is determined predominantly by the industrial culture. The transfer of the dominant cultural elements does not only lead to the deletion of specific knowledge of indigenous cultures, but also of context-relevant behaviour patterns of those concerned, who then participate in the destruction of the environment with the further effects of erosion, loss of species, and climate change. Yet, a representation of those mechanisms in functional models helps to define effective methods of intervention. (shrink)

This paper is intended as a critical examination of the question of when and under what conditions the use of computer simulations is beneficial to scientific explanations. This objective is pursued in two steps: First, I try to establish clear criteria that simulations must meet in order to be explanatory. Basically, a simulation has explanatory power only if it includes all causally relevant factors of a given empirical configuration and if the simulation delivers stable results within the measurement inaccuracies of (...) the input parameters. -/- In the second step, I examine a few examples of Axelrod-style simulations as they have been used to understand the evolution of cooperation (Axelrod, Schüßler). These simulations do not meet the criteria for explanatory validity and it can be shown, as I believe, that they lead us astray from the scientific problems they have been addressed to solve.

In this paper we investigate with a case study from chemistry under what conditions a simulation can serve as a surrogate for an experiment. The case-study concerns a simulation of H2-formation in outer space. We find that in this case the simulation can act as a surrogate for an experiment, because there exists comprehensive theoretical background knowledge in form of quantum mechanics about the range of phenomena to which the investigated process belongs and because any particular modelling assumptions as can (...) be justified. If these requirements are met then direct empirical validation may even be dispensable. We conjecture that this is not the case in the absence of comprehensive theoretical background knowledge.

Mathematical models are a well established tool in most natural sciences. Although models have been neglected by the philosophy of science for a long time, their epistemological status as a link between theory and reality is now fairly well understood. However, regarding the epistemological status of mathematical models in the social sciences, there still exists a considerable unclarity. In my paper I argue that this results from specific challenges that mathematical models and especially computer simulations face in the social sciences. (...) The most important difference between the social sciences and the natural sciences with respect to modeling is that in the social sciences powerful and well confirmed background theories (like Newtonian mechanics, quantum mechanics or the theory of relativity in physics) do not exist in the social sciences. Therefore, an epistemology of models that is formed on the role model of physics may not be appropriate for the social sciences. I discuss the challenges that modeling faces in the social sciences and point out their epistemological consequences. The most important consequences are that greater emphasis must be placed on empirical validation than on theoretical validation and that the relevance of purely theoretical simulations is strongly limited.

Hans Kelsens Critique of Eric Voegelins "New Science of Politics" has for a long time been very difficult to access, because Kelsen has published only parts of it in his life time and left other parts unpublished. This allowed Voegelin to spread the myth that Kelsen had refrained from publishing his criticism, because he had understood that he was wrong. This is nonsense. The reasons why Kelsen left part of his criticism unpublished are mostly accidental. At the same time Kelsens (...) criticism itself is a very sound rejection of Voegelin's hopelessly flawed theory of modernity as an age of Gnosticism. In this Nachwort to the Edition of Kelsen's Voegelin-criticism I summarize and comment the most important points of Kelsens criticism: 1. Kelsen's take on Voegelin's criticism of positivism. 2. Kelsen's rejection of Voegelin's "theory of representation" which is in fact a rejection of democratic representation in favor of an authoritarian and theocratic model of politics and 3. Kelsen's refuation of Voegelin's explanation of political disorder in the 20th century as a result of Gnostic heresy. My conclusion is that Kelen's criticism is successful (with only very minor qualifications) in all of these points and that thus it is an important contribution to the discussion of Voegelin's scholarship which has until recently been almost entirely apologetic.

Bartha and DesRoches (2021) and Steel and Bartha (2023) argue that we should understand the precautionary principle as the injunction to maximise lexical utilities. They show that the lexical utility model has important pragmatic advantages. Moreover, the model has the theoretical advantage of satisfying all axioms of expected utility theory except continuity. In this paper I raise a trilemma for any attempt at modelling the precautionary principle with lexical utilities: it permits choice cycles or leads to paralysis or implies that (...) the smallest value difference that is possible in a context has extreme axiological implications.

There are many advantages and disadvantages to central locations. These have shown themselves in the long course of European history. In times of peace, there are important economic and cultural advantages (to illustrate: the present area of the Czech Republic was the richest country in Europe between the two World Wars). There are cross-currents of trade and culture in central Europe of great advantage. For, cultural cross-currents represent a potential benefit in comprehension and cultural growth. But under threat of large-scale (...) conflict, these locations have proved extremely dangerous. Historically, Germany and Austria may be regarded as having had two chief models of their relationships to Europe. In the Holy Roman Empire, Germany was at the center of an aspiring “universalistic” European cosmopolitanism. (In some ways similar to the present situation of the European Union.) Austria maintained a great multi¬cultural empire, until it was destroyed in the First Word War. Generally, middle-European powers have promoted the integration of European diversity, when peace and stability have been plausible objectives. But when European diversity has declined toward ethnic or national conflict, Germany has drawn away from Europe and into itself, seeking inner unity and distinctness to protect it against possible combinations of enemies. This is true of central Europe generally, in degree, but interest often centers on Germany. Generally, central Europe is a cultural pressure cooker. (shrink)

Buddhism originated and developed in an Indian cultural context that featured many first-person practices for producing and exploring states of consciousness through the systematic training of attention. In contrast, the dominant methods of investigating the mind in Western cognitive science have emphasized third-person observation of the brain and behavior. In this chapter, we explore how these two different projects might prove mutually beneficial. We lay the groundwork for a cross-cultural cognitive science by using one traditional Buddhist model of the mind (...) – that of the five aggregates – as a lens for examining contemporary cognitive science conceptions of consciousness.

According to advocates of internalism about reasons for action, there is an interesting connection between an agent’s reasons and the agent’s present desires. On the simplest version of this view, an agent has a reason to act a certain way at some time if and only if acting that way would promote his present desires. Let us call this the sub-Humean model.1 The sub-Humean model is widely regarded as too simple on the grounds that there are adverse conditions, such as (...) massive confusion, in which desires are irrationally possessed or acquired, thereby failing to provide reasons for action.2.

Much problem solving and learning research in math and science has focused on formal representations. Recently researchers have documented the use of unschooled strategies for solving daily problems -- informal strategies which can be as effective, and sometimes as sophisticated, as school-taught formalisms. Our research focuses on how formal and informal strategies interact in the process of doing and learning mathematics. We found that combining informal and formal strategies is more effective than single strategies. We provide a theoretical account of (...) this multiple strategy effect and have begun to formulate this theory in an ACT-R computer model. We show why students may reach common impasses in the use of written algebra, and how subsequent or concurrent use of informal strategies leads to better problem-solving performance. Formal strategies facilitate computation because of their abstract and syntactic nature; however, abstraction can lead to nonsensical interpretations and conceptual errors. Reapplying the formal strategy will not repair such errors; switching to an informal one may. We explain the multiple strategy effect as a complementary relationship between the computational efficiency of formal strategies and the sense-making function of informal strategies. (shrink)

In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943–1953); (2) the latency period, with a focus on the development of basic skills (1953–1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989–2003) and (4) (...) adulthood (2003–present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy—have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as ‘relevance’, ‘responsible innovation’ and ‘promise management’.

It is proposed that our memory is made up of individual, unconnected Records, to each of which is attached a Heading. Retrieval of a Record can only be accomplished by addressing the attached Heading, the contents of which cannot itself be retrieved. Each Heading is made up of a mixture of content in more or less literal form and context, the latter including specification of environment and of internal states (e.g. drug states and mood). This view of memory allows an (...) easy account of a number of natural memory phenomena as well as a variety of laboratory findings such as the differences between recall and recognition. The theory further proposes that Headed Records can neither be deleted nor modified. Data apparently against such a hypothesis can be accounted for in terms of the retrieval process. (shrink)

A pineapple is a tropical plant with eatable leafy foods most monetarily critical plant in the family Bromeliaceous. The pineapple is native to South America, where it has been developed for a long time. The acquaintance of the pineapple with Europe in the seventeenth century made it a critical social symbol of extravagance. Since the 1820s, pineapple has been industrially filled in nurseries and numerous tropical manors. Further, it is the third most significant tropical natural product in world creation. In (...) the twentieth century, Hawaii was a prevailing maker of pineapples, particularly for the US, be that as it may, by 2016, Costa Rica, Brazil, and the Philippines represented almost 33% of the world's creation of pineapples.

A deep learning technique that extensively applied to image recognition was used. use 70% from image for training and 30% from image for validation.

Ecological neutral theory has been controversial as an alternative to niche theory for explaining community structure. Neutral theory, which explains community structure in terms of ecological drift, is frequently charged with being unrealistic, but commentators have usually not provided an account of theory or model realism. In this paper, I propose a framework for comparing the “realism” or accuracy of alternative theories within a domain with respect to the extent to which the theories abstract and idealize. Using this framework I (...) argue, contrary to most previous commentators, that neutral and niche theories are similarly realistic. Realism cannot provide a basis for accepting or rejecting either type of theory; instead, community ecologists should continue working with a plurality of models. While theoretical unification may become possible, we should treat a plurality of complementary, partial models as the expected situation within community ecology. (shrink)

I suggest that the post-Hegelian tradition presents us with three contrasting normative models of work. According to the first model, the core norms of work are those of means-ends rationality. In this model, the modern world of work is constitutively a matter of deploying the most effective means to bring about given ends. The rational kernel of modern work, the core norm that has shaped its development, is on this view instrumental reason, and this very same normative core, in the (...) shape of advanced technology and more efficient, time-saving production, can help to liberate it. The second model, by contrast, takes the core norms of work to be internal to working activity. Rather than work gaining its normativity from something external to it, from ends to which the work is a contingent means, on this second view the core norms of work are expressions of values or meanings that are immanent to working practices themselves. The expressive model of work regards the actual world of work to be constituted historically by work-specific norms, norms which working subjects themselves have invoked and mobilised around in the course of their struggles for emancipation. According to the third model, the core norms of work have to do neither with instrumental rationality nor authentic self-expression. Rather they concern norms that relate either to individual achievement or contribution through work (in the form of esteem) or to the conditions that must in place for individuals to participate in the exchange of services by which market societies reproduce themselves (in the form of mutual respect).

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

Music, alongside ritual, plays an important role in Confucian moral education. Among all the Confucians, Xunzi gives music the most radical ability to transform people, and this is striking given his pessimistic view of human nature. Though he set the standard for Chinese aesthetics for millennia, there’s no systematic account that brings together Xunzi’s various commitments: that only music from virtuous previous dynasties are morally conducive, that music can bring about lasting character change, that even those uninterested in moral cultivation (...) can benefit from music, and that the junzi (“gentleman”) and the xiaoren (“petty man”) derive joy in different ways while listening to music. In this article, I explain why currently existing accounts can’t capture all the commitments, and I turn to analytic aesthetics to provide a new Dual-Process Model of Xunzi’s philosophy of music. Jenefer Robinson’s discussions of “the Jazzercise effect” and emotional misattribution will be key in the new account. (shrink)

In order to strengthen RI in the private sector, it is imperative to understand how companies organise this process, where it takes place, and what considerations and motivations are central in the innovation process. In this chapter, the questions of whether and where normative considerations play a role in the innovation process, and whether dimensions of RI are present in the innovation process, are addressed. In order answer these research questions, a theoretical framework is developed based on Jones’s theory of (...) ethical decision making and Cooper’s stagegate model of innovation management. In order to answer the research questions, a specific case of innovations that contribute to public health is explored, namely, that of food companies that participate in a Front-of-Pack logo for healthier food. As the use of healthy food logos does not necessarily have a positive impact on sales and profits, it is expected that in the decision-making process, as part of their innovation process, companies make several trade-offs between economic, technical and moral factors. As the social-ethical values at stake in corporate innovation processes have remained to a large extent unexplored in research on innovation management, the aim of this chapter is to identify the motivations and barriers for companies embracing and continuing a FoP logo for healthier food, and to assess whether ethical considerations play a role in this innovation process. From the findings in this research, it will become clear that although the studied companies participated in a programme for healthy food and thus are responsive to the needs of society, and although the companies feel responsible for public health, ethical considerations do not play a central role in the operational innovation process. Instead, technical and economic considerations seem to prevail in the operational innovation process. Furthermore, none of the procedural dimensions of RI seems to be present at this level in the innovation trajectory. It is argued that this may be an indication that the ethical decision-making process for RI is not located at the level of the operational innovation process itself, but is something that might be located on a higher strategic level in the company. It is at this level that the moral decision is taken to adopt the FoP logo and to engage in the RI process. The findings cast a new light on the discourse on RI in general, and in the private sector in particular. (shrink)

There are a bewildering variety of claims connecting Darwin to nineteenth-century philosophy of science—including to Herschel, Whewell, Lyell, German Romanticism, Comte, and others. I argue here that Herschel’s influence on Darwin is undeniable. The form of this influence, however, is often misunderstood. Darwin was not merely taking the concept of “analogy” from Herschel, nor was he combining such an analogy with a consilience as argued for by Whewell. On the contrary, Darwin’s Origin is written in precisely the manner that one (...) would expect were Darwin attempting to model his work on the precepts found in Herschel’s Preliminary Discourse on Natural Science. While Hodge has worked out a careful interpretation of both Darwin and Herschel, drawing similar conclusions, his interpretation misreads Herschel’s use of the vera causa principle and the verification of hypotheses. The new reading that I present here resolves this trouble, combining Hodge’s careful treatment of the structure of the Origin with a more cautious understanding of Herschel’s philosophy of science. This interpretation lets us understand why Darwin laid out the Origin in the way that he did and also why Herschel so strongly disagreed, including in Herschel’s heretofore unanalyzed marginalia in his copy of Darwin’s book.

Philosophers of biology have worked extensively on how we ought best to interpret the probabilities which arise throughout evolutionary theory. In spite of this substantial work, however, much of the debate has remained persistently intractable. I offer the example of Bayesian models of divergence time estimation as a case study in how we might bring further resources from the biological literature to bear on these debates. These models offer us an example in which a number of different sources of uncertainty (...) are combined to produce an estimate for a complex, unobservable quantity. These models have been carefully analyzed in recent biological work, which has determined the relationship between these sources of uncertainty, both quantitatively and qualitatively. I suggest here that this case shows us the limitations of univocal analyses of probability in evolution, as well as the simple dichotomy between “subjective” and “objective” probabilities, and I conclude by gesturing toward ways in which we might introduce more sophisticated interpretive taxonomies of probability as a path toward advancing debates on probability in the life sciences.

In Legality Scott Shapiro seeks to provide the motivation for the development of his own elaborate account of law by undertaking a critique of H.L.A. Hart's jurisprudential theory. Hart maintained that every legal system is underlain by a rule of recognition through which officials of the system identify the norms that belong to the system as laws. Shapiro argues that Hart's remarks on the rule of recognition are confused and that his model of lawis consequently untenable. Shapiro contends that a (...) new approach is vital for progress in the philosophy of law and, with his lengthy presentation of his own Planning Theory of Law, he aspires to pioneer just such an approach. Except for a very terse observation in the final main section, this article does not directly assess the strengths and shortcomings of Shapiro's piquant planning theory. Instead, I defend Hart against Shapiro's charges and thereby undermine the motivation for the development of the planning theory. (shrink)

Through the benefits of trade openness, diversification, and economic competitiveness, the UAE was successful in its economic endeavors by creating economic winners and protecting those who have been hurt by the embrace of globalization. The country also paid special attention to the issues of wealth distribution and fairness in the allocation of economic resources (inclusive globalization). The most important lesson from UAE’s economic growth is that strong formal institutions with sound vision designed to propel economic development are keys for success.

The complexity and heterogeneity of causes influencing ecology’s domain challenge its capacity to generate a general theory without exceptions, raising the question of whether ecology is capable, even in principle, of achieving the sort of theoretical success enjoyed by physics. Weber has argued that competition theory built around the Competitive Exclusion Principle (especially Tilman’s resource-competition model) offers an example of ecology identifying a law-like causal regularity. However, I suggest that as Weber presents it, the CEP is not yet a causal (...) regularity. Instead, I argue that the scientific understanding in Tilman’s theory takes a different form. The theory explains through a structure I call “channeling explanation” which does not depend on deduction from general laws, but rather builds on constraints and trade-offs represented in state-space. Recognizing this structure supports the more general point that ecology and other so-called special sciences can reveal novel theoretical approaches to philosophy of science when approached with openness to their uniqueness.

A quarter of a century ago, the first systematic behavioral experiments were performed to clarify the nature of color constancy—the effect whereby the perceived color of a surface remains constant despite changes in the spectrum of the illumination. At about the same time, new models of color constancy appeared, along with physiological data on cortical mechanisms and photographic colorimetric measurements of natural scenes. Since then, as this review shows, there have been many advances. The theoretical requirements for constancy have been (...) better delineated and the range of experimental techniques has been greatly expanded; novel invariant properties of images and a variety of neural mechanisms have been identified; and increasing recognition has been given to the relevance of natural surfaces and scenes as laboratory stimuli. Even so, there remain many theoretical and experimental challenges, not least to develop an account of color constancy that goes beyond deterministic and relatively simple laboratory stimuli and instead deals with the intrinsically variable nature of surfaces and illuminations present in the natural world.

In this paper, machine learning based approach is presented for classifying and identifying 10 different fruit with a dataset that contains 6847 images use 4793 images for training, 1027 images for validation and 1027 images for testing. A deep learning technique that extensively applied to image recognition was used. We used 70% from image for training and 15% from image for validation 15% for testing. Our trained model achieved an accuracy of 100% on a held-out test set, demonstrating the feasibility of this approach. (shrink)

The current informal practice of pharmacometrics as a combination art and science makes it hard to appreciate the role that informatics can and should play in the future of the discipline and to comprehend the gaps that exist because of its absence. The development of pharmacometric informatics has important implications for expediting decision making and for improving the reliability of decisions made in model-based development. We argue that well-defined informatics for pharmacometrics can lead to much needed improvements in the efficiency, (...) effectiveness, and reliability of the pharmacometrics process. The purpose of this paper is to provide a description of the pervasive yet often poorly appreciated role of informatics in improving the process of data assembly, a critical task in the delivery of pharmacometric analysis results. First, we provide a brief description of the pharmacometric analysis process. Second, we describe the business processes required to create analysis-ready data sets for the pharmacometrician. Third, we describe selected informatic elements required to support the pharmacometrics and data assembly processes. Finally, we offer specific suggestions for performing a systematic analysis of existing challenges as an approach to defi ning the next generation of pharmacometric informatics. (shrink)

We (...) naturally chose, arbitrarily, 1,000 distinctive stimuli for this research. We made certain that the scattering remnants the similar after selecting the one thousand stimuli.

What is the fundamental purpose that justifies the existence of the modern university? The answer proposed in this essay is the promotion of social freedom. The essay begins by distinguishing social freedom from negative freedom and reflective freedom along the lines proposed by other theorists of social freedom, such as Frederick Neuhouser and Axel Honneth. After noting the need for a more developed account of the university than has so far been provided by these other theorists, the essay analyses the (...) various dimensions in which universities have, at their best, promoted social freedom. The essay then explains why it is through the promotion of social, as distinct from negative or reflective freedom, that universities fulfil their purpose. It concludes with some reflections on how this understanding of the purpose of the university fits an “immanent” model of social criticism. (shrink)

Respiratory rhythms sustain biological life, governing the homeostatic exchange of oxygen and carbon dioxide. Until recently, however, the influence of breathing on the brain has largely been overlooked. Yet new evidence demonstrates that the act of breathing exerts a substantive, rhythmic influence on perception, emotion, and cognition, largely through the direct modulation of neural oscillations. Here, we synthesize these findings to motivate a new predictive coding model of respiratory brain coupling, in which breathing rhythmically modulates both local and global neural (...) gain, to optimize cognitive and affective processing. Our model further explains how respiratory rhythms interact with the topology of the functional connectome, and we highlight key implications for the computational psychiatry of disordered respiratory and interoceptive inference.

It has been difficult to define human consciousness because of its many differing qualities and because of various views people have of consciousness. It is proposed that these multiple vantage points be united into a single three-dimensional model utilizing breadth, time and depth. This model could provide a more comprehensive definition of consciousness and encourage an exploration of the interplay of consciousness’ many features. Such a model may also help answer some of the many questions that the concept of consciousness (...) creates. (shrink)

This paper defends the idea that phenomenological approaches to self-consciousness can enrich the current analytic philosophy of perception, by showing how phenomenological discussions of minimal self-consciousness can enhance our understanding of the phenomenology of conscious perceptual experiences. As a case study, I investigate the nature of the relationship between naïve realism, a contemporary Anglophone theory of perception, and experiential minimalism (or, the ‘minimal self’ view), a pre-reflective model of self-consciousness originated in the Phenomenological tradition. I argue that naïve realism is (...) not only compatible with, but can be supplemented with experiential minimalism in a novel way. The suggestion is that there are reasons to combine naïve realism and experiential minimalism. My focus here will be on drawing a connection between the notion of minimal self and two core theoretical commitments of naïve realism, relationalism and transparency. (shrink)

The flipped-classroom format is a type of blended learning where students are required to do preparatory work – such as watching lecture videos or completing assignments – before coming to a face-to-face class to work on more challenging problems with the facilitation of an instructor. However, one challenge of teaching flipped-classroom modules is that a big proportion of students often come to class unprepared. Either they do not watch the lecture videos or they skim through them before the tutorials. Thus, (...) they lack a proper understanding of the content and many are unable to participate in class activities. The tutorial ends up becoming a lecture where we go over the basic content instead of challenging the students to take their learning further. In this article, I explain explains how I designed learning activities to ensure students complete the preparation work necessary to get the most out of the flipped-classroom model. (shrink)

Understanding choice of family planning provider is fundamental for policy makers and program managers as they seek ways to both improve the coverage and increase the sustainability and efficiency of family planning services for Egypt to achieve its population objectives. This study focuses first on providing a descriptive profile of the patterns of reliance on sources of family planning services during the early 2000s. Binomial logit models are then estimated to obtain a more in depth understanding of the determinants of (...) the choice of family planning providers in Egypt using the 2000 Egypt Demographic and Health Survey. The study offers insights into a number of aspects of family planning service provision about which there has been less previous investigation. There are marked differences in the extent to which Egyptian women rely on public or private providers for family planning services depending on the type of method they are seeking. Among the more important findings is the consistency women display in the choice of provider among women reporting multiple segments of use. With regard to the determinants of the choice of provider for family planning services, perhaps the most interesting finding is that household wealth was not a significant determinant of the choice of provider. This may reflect that private sources met the demand for family planning services of significant proportions of women in rural areas and among those in the low income groups. (shrink)

Brain-related diseases are among the most difficult diseases due to their sensitivity, the difficulty of performing operations, and their high costs. In contrast, the operation is not necessary to succeed, as the results of the operation may be unsuccessful. One of the most common diseases that affect the brain is Alzheimer’s disease, which affects adults, a disease that leads to memory loss and forgetting information in varying degrees. According to the condition of each patient. For these reasons, it is important (...) to classify memory loss and to know the patient at what level and his assessment of Alzheimer's disease through CT scans of the brain. In this thesis, we review ways and techniques to use deep learning classification to classifying the Alzheimer's Disease The proposed method used to improve patient care, reduce costs, and allow fast and reliable analysis in large studies. The model will be designed using Python language for implementing the system, which is very useful for doctors, classifying the Alzheimer's Disease, was used. The model used 70% from image for training and 30% from image for validation, our trained model achieved an accuracy of 100% on a held-out test set. (shrink)

This study aims to determine driving factors significantly influencing the purchase intention and to identify impediments creating the intention –behavior gap regarding organic food consumption in Vietnam. The chosen driving factors affecting the organic food purchase intention in this study are health benefits, environmental awareness, and social norms, whereas trust, price, and convenience as well as availability are investigated as deterrent factors of the link between intention and behavior. A structured online questionnaire with snow-balling sampling method was distributed to collect (...) a representative sample of 466 Vietnamese consumers nationwide. A five-point likert scale was used for the level of approval for 36 statements. Statistical tools of SPSS 22.0 including descriptive analysis, principal component analysis, and multiple regression analysis models were used for data analysis. The results showed that health benefits, environmental awareness, and social norms were facilitators of organic food purchase intention. Although high intention to purchase organic foods was identified in Vietnam, it was not translated into actual purchase behavior. The main barriers for the inconsistency were premium price and low availability of organic products or inconvenience to buy in the market. Lack of trust insignificantly impacted on organic food choices among Vietnamese consumers in this study. These empirical findings and suggestions are beneficial for all players across supply chains.

Abstract: Nowadays fresh water severe scarcity is a global concern and it is alarming for the future. In order to fully understand the progress of the water system and its impacts, a sustainability assessment of water resources is needed. This accelerates the achievement of sustainability and management of water resources. This work aims to assess the sustainability of the water resources system by applying the integration approach proposed by (Xu, 2011). This integration approach is based on integrating the DPSIR-ANP method (...) to the System Dynamics (SD) model, which is considered as a unique work in water resources management field. SD is a computer simulation model to understanding the behavior of complex systems over time, while Analytic Network Process (ANP) is a decision finding method used in model complex decision problems which contains feedback connections and loops. DPSIR is an analytical framework for describing the interactions between the economy, society and the environment. This integrated approach enables decision makers to view the sustainability problems of water resources system more comprehensively. The results showed that there is an increasing impact on the sustainability of water resources systems in Egypt over the research period. This is attributed to the increase in water resources consumption due to the increase in population, agriculture expansion and an increase in the value of GDP. So, the officials for managing water resources in Egypt should take actions to increase the efficiency of water use and increasing the renewable water resources for compensating water shortage.

This thesis considers the following problem: What methods should the epistemology of science use to gain insight into the structure and behaviour of scientific knowledge and method in actual scientific practice? After arguing that the elucidation of epistemological and methodological phenomena in science requires a method that is rooted in formal methods, I consider two alternative methods for epistemology of science. One approach is the classical approaches of the syntactic and semantic views of theories. I show that typical approaches of (...) this sort are inadequate and inaccurate in their representation of scientific knowledge by showing how they fail to account for and misrepresent important epistemological structure and behaviour in science. The other method for epistemology of science I consider is modeled on the methods used to construct valid models of natural phenomena in applied mathematics. This new epistemological method is itself a modeling method that is developed through the detailed consideration of two main examples of theory application in science: double pendulum systems and the modeling of near-Earth objects to compute probability of future Earth impact. I show that not only does this new method accurately represent actual methods used to apply theories in applied mathematics, it also reveals interesting structural and behavioural patterns in the application process and gives insight into what underlies the stability of methods of application. I therefore conclude that for epistemology of science to develop fully as a scientific discipline it must use methods from applied mathematics, not only methods from pure mathematics and metamathematics as traditional formal epistemology of science has done.

Technology and Artificial Intelligence, both today and in the near future, are dominated by automated algorithms that combine optimization with models based on the human brain to learn, predict, and even influence the large-scale behavior of human users. Such applications can be understood to be outgrowths of historical trends in industry and academia, yet have far-reaching and even unintended consequences for social and political life around the world. Countries in different parts of the world take different regulatory views for the (...) role and protection of user data, and this will in turn determine the course of development for technology and AI in the near future.

Wat betreft economische groei en ontwikkeling van de werkloosheid heeft de Nederlandse economie het sinds 1973 slechter gedaan dan andere OECD-landen. Op de vraag naar de oorzaken van die slechte prestatie zijn in het verleden uiteenlopende antwoorden gegeven door o.m. Bomhoff en Clavaux. Ook zijn er diverse wegen aangegeven om op te rukken naar een betere positie. In dit artikel presenteren de auteurs de resultaten van een internationale doorsnee-analyse om de verschillen in economisch succes tussen landen met behulp van een (...) eenvoudig neo-klassiek macro-economisch model te verklaren. Dit biedt de mogelijkheid om te traceren wat de rol van de exportgroei, de groei van de bevolking, de wisselkoers, de verhouding tussen de binnenlandse en de buitenlandse prijsontwikkeling en de investeringsquote voor verschillen in economische ontwikkeling is geweest. Vooral de uitvoer gecorrigeerd voor de omvang van de bevolking, de investeringsquote en de nominale wisselkoers komen als belangrijke verklarende variabelen naar voren. Op grond van hun analyse komen de auteurs tot de conclusie dat een beleid gericht op het verbeteren van de Nederlandse economische prestatie op lange termijn zich vooral zou moeten concentreren op het benutten van exportkansen en op een hoog investeringsniveau ter bevordering van technologische vernieuwing en daarmee verbetering van de concurrentiepositie. Daarbij moet worden voorkomen dat revaluatie van de gulden het exporteffect teniet doet. (shrink)

Vaccine research, as well as the development, testing, clinical trials, and commercial uses of vaccines involve complex processes with various biological data that include gene and protein expression, analysis of molecular and cellular interactions, study of tissue and whole body responses, and extensive epidemiological modeling. Although many data resources are available to meet different aspects of vaccine needs, it remains a challenge how we are to standardize vaccine annotation, integrate data about varied vaccine types and resources, and support advanced vaccine (...) data analysis and inference. To address these problems, the community-based Vaccine Ontology (VO) has been developed through collaboration with vaccine researchers and many national and international centers and programs, including the National Center for Biomedical Ontology (NCBO), the Infectious Disease Ontology (IDO) Initiative, and the Ontology for Biomedical Investigations (OBI). VO utilizes the Basic Formal Ontology (BFO) as the top ontology and the Relation Ontology (RO) for definition of term relationships. VO is represented in the Web Ontology Language (OWL) and edited using the Protégé-OWL. Currently VO contains more than 2000 terms and relationships. VO emphasizes on classification of vaccines and vaccine components, vaccine quality and phenotypes, and host immune response to vaccines. These reflect different aspects of vaccine composition and biology and can thus be used to model individual vaccines. More than 200 licensed vaccines and many vaccine candidates in research or clinical trials have been modeled in VO. VO is being used for vaccine literature mining through collaboration with the National Center for Integrative Biomedical Informatics (NCIBI). Multiple VO applications will be presented. (shrink)

Corruption in public institutions is a significant problem that stifles economic, social and environmental development worldwide. This predominates when there is a lack of transparency, inadequate record-keeping, and low public accountability. Accordingly, the questions this paper intends to provide answers to are two-fold. Firstly, what are the recurring patterns of procurement corruption in the South Africa (SA) public sector? Secondly, how can digital technology deployment assist in checking this trend? Desktop method was adopted through literature examination of studies relating to (...) corruption, procurement, blockchain and digitization. We conclude by proposing a model/framework for adopting and using blockchain technology in public institutions to minimise corruption and the time taken for contract document preparation and acceptance. This study contributed to knowledge by evaluating the issues associated with public procurement and how blockchain and digitization can be adopted to help stern the tide of corruption in public institutions.
