Diagrams are a form of spatial representation that supports reasoning and problem solving. Even when diagrams are external, not to mention when there are no external representations, problem solving often calls for internal representations, that is, representations in cognition, of diagrammatic elements and internal perceptions on them. General cognitive architectures—Soar and ACT-R, to name the most prominent—do not have representations and operations to support diagrammatic reasoning. In this article, we examine some requirements for such internal representations and processes in cognitive (...) architectures. We discuss the degree to which DRS, our earlier proposal for such an internal representation for diagrams, meets these requirements. In DRS, the diagrams are not raw images, but a composition of objects that can be individuated and thus symbolized, while, unlike traditional symbols, the referent of the symbol is an object that retains its perceptual essence, namely, its spatiality. This duality provides a way to resolve what anti-imagists thought was a contradiction in mental imagery: the compositionality of mental images that seemed to be unique to symbol systems, and their support of a perceptual experience of images and some types of perception on them. We briefly review the use of DRS to augment Soar and ACT-R with a diagrammatic representation component. We identify issues for further research. (shrink)

That diagrams are analog, i.e., homomorphic, representations of some kind, and sentential representations are not, is a generally held intuition. In this paper, we develop a formal framework in which the claim can be stated and examined, and certain puzzles resolved. We start by asking how physical things can represent information in some target domain. We lay a basis for investigating possible homomorphisms by modeling both the physical medium and the target domain as sets of variables, each with a constraint (...) structure. When a homomorphism exists, the causality of the physical medium can provide a “free ride,” automatically determining the information that is needed to solve a problem. The modeling technique enables us to show how in sentential representations the structure of the 2-D space is used non-homomorphically to define tokens, and to provide a minimal homomorphism with respect to the ordering of the arguments for n-ary functions, predicates, and operators, but otherwise there is no homomorphism with the target domain. Our treatment also characterizes diagrams as a type of a more general class of physical representations in which physical causality plays a role in providing the information needed to solve a problem.

Formal charge and oxidation state are two means of estimating the charge of an atom in a molecule. Though these concepts have very different origins—formal charge is derived from the ball-and-hook model of bonding and oxidation state is based on the ionic approximation of molecules—they are used to predict reactivity and other molecular properties through their properties as charges. In this submission, it is shown that formal charge and oxidation state are two extreme descriptions of bonding: formal charge represents zero (...) charge transfer between atoms while oxidation state represents complete charge transfer in each bond. These ‘localised electron approximations’ form an incomplete picture of atomic charge. Electronegativity measures the extent of polarity in real bonds; this concept can be introduced to polarise bonds relative to the ‘equal sharing model’. It is shown that the various electronegativity models are fundamentally related. We chose two models to demonstrate numerically that polar bonds yield charges intermediate between the localised electron approximations: Pauling and Mulliken. It is shown that probabilistic interpretation of the Pauling scale (‘scaled Pauling’ method) and use of asymmetric chemical potential (‘modified Mulliken’ method) lead to atomic charges that closely approximate experimental values using simple ‘back of the envelope’ calculations. It is seen that formal charge, oxidation state, and electronegativity-interpolated charge lie on a continuum and are mathematically related. It is therefore concluded that electronegativity introduces (quantum) delocalisation to the localised (classical) picture of electron bonding. (shrink)

This manuscript explores the orthogonality constraints on configurations and orbitals subject to the property that states are mutually orthogonal. The orthogonality constraints lead to properties that affect the description of chemical systems. When states are described as linear combinations of configurations, the coefficient matrix diagonalises S−1H. Therefore, single-configuration states are only possible in one-electron systems: non-orthogonal configurations yield single-configuration states only if S−1H is diagonal, but this would violate the orthonormalisation constraint. Further, the coefficient matrix is not constrained to be (...) square. Similarly, the orbitals used to construct configurations may also be orthogonal or non-orthogonal; orbitals are only required to be mutually orthogonal at the one-electron limit. Orthogonal orbitals are generally preferred due to their mathematical and conceptual simplicity, leading to fictitious unoccupied orbitals. Since the Fock operator is orthogonality agnostic, non-orthogonal orbitals can be generated by solving the Fock equation independently for each electron; the virtual orbitals produced by this conception are true excitation orbitals as they are eigensolutions of the Fock operator. Additionally, we show that the number of molecular orbitals generated is not restricted to the number of atomic orbitals employed in the computation. This manuscript explores the mathematical relationships that need to be satisfied under the various orthogonality regimes. We also present mathematical relationships that provide results that are independent of the orthogonality approximation within a particular computational method. (shrink)

In recent years, numerous researches have been conducted on CSR from various perspectives. From a survey of CSR literatures from spiritual and religious perspectives, there are some studies based on the Quran and the Bible made by scholars. However, the Bhagavad-Gita is yet to be explored in the context of CSR. This article is therefore timely and fills the gap in the CSR literature. In this article, the authors employs hermeneutics, a qualitative research methodology which involves the study, understanding and (...) interpretation of the BG particularly the concept of ‘dharma’ and ‘karma’ in the context of CSR. In a nutshell, the BG provides an inside-out approach to CSR, which is the development of individual leader’s self-conscience of his1 dharma and karma. Based on the BG’s insights, CSR should ideally begin with ISR and to go beyond CSR with GSR. These three social responsibilities are the essential dharma and karma of corporate leaders. The leaders and the role they play in corporations are crucial in ensuring transparency, good conduct and governance towards the ultimate aim of achieving CSR. This article is expected to provide a framework to the study of BG philosophy from other aspects of corporate management; such as corporate governance, corporate ethics and human resource management in the near future.

Slater’s method is an integral part of the undergraduate experience. In actuality, Slater’s method is part of an atomic model and not simply a set of rules. Slater’s rules are a simple means for computing the effective nuclear charge experienced by an orbital. These rules are based on the shell-like structure of the Slater atom in which outer shell electrons are incapable of shielding inner electrons. Slater’s model provides a qualitative description of the valence electrons in multi-electron atoms with tremendous (...) ease. The model is useful for explaining atomic properties such as ionisation energy, electron affinity and atomic radius qualitatively. Slater’s rules also correctly reproduce the Madelung rule of filling and the ionisation sequence (4s before 3d); however, these rules are not able to reproduce the anomalous configurations of atoms such as Cr and Cu. It is found that the atomic properties that Slater’s model reproduces are all related to the exponential decay factor of the Slater orbital. We find—from estimating the polarity of a diatomic molecule using a simple model—that molecular polarity is related to the difference in the exponential decay factors of the valence orbitals of the two atoms, implying that the decay factor acts as the electronegativity of the atom.

Judicial activism is a contested phenomenon, with the liberals and even the conservatives championing it while denouncing its particular manifestations. In this article, I examine the recent judicial practice of one of the most activist judiciaries in the world, that of India, where progressive politics is often, and sometimes always, associated with an activist and benign court. Indeed, the Indian Supreme Court has a global reputation as a torchbearer on human rights. In this article, I adopt a social movement perspective (...) to understand the actual impact of the court on the struggles of the poor for livelihood, resources, values, and identity, enacted through struggles for the recognition and realization of economic, social, and cultural rights. After an analysis of the record of the Supreme Court of India, I conclude that the Court has increasingly shown a bias against the poor in its activist rulings and made judicial activism a more problematic device for social movements in India to rely upon. To explain why this is happening, the article introduces two ideas: first, the emergence of the judiciary as an organ of governance and its attendant problems, and second, the internally biased nature of the rights discourse which tends to reproduce binary arguments for either increasing State capacity or for increasing choice of goods in the marketplace. The article concludes by exploring lessons from the jurisprudence of other countries and international law and urges the Indian Supreme Court to reinvent a jurisprudence informed more by the social movements of the poor.

Mohandas Karamchand “Mahatma” Gandhi discussed corporate responsibility and business ethics over several decades of the twentieth century. His views are still influential in modern India. In this paper, we highlight Gandhi’s cross-level CR framework, which operates at institutional, organizational, and individual levels. We also outline how the Tata Group, one of India’s largest conglomerates, has historically applied and continues to utilize Gandhi’s concept of trusteeship. We then compare Gandhi’s framework to modern notions of stakeholder and stewardship management. We conclude that (...) trusteeship has strong potential to help firms and their stakeholders achieve shared value by considering the interactions between individual, organizational, and institutional factors, and paying attention to a range of multi-level stakeholder obligations.

This paper reports the findings of a comparative study in which students’ perceived attainment of the objectives of an engineering ethics education and their attitude towards engineering ethics were investigated and compared. The investigation was carried out in Japan and Malaysia, involving 163 and 108 engineering undergraduates respectively. The research method used was based on a survey in which respondents were sent a questionnaire to elicit relevant data. Both descriptive and inferential statistical analyses were performed on the data. The results (...) of the analyses showed that the attainment of the objectives of engineering ethics education and students’ attitude towards socio-ethical issues in engineering were significantly higher and positive among Japanese engineering students compared to Malaysian engineering students. Such findings suggest that a well-structured, integrated, and innovative pedagogy for teaching ethics will have an impact on the students’ attainment of ethics education objectives and their attitude towards engineering ethics. As such, the research findings serve as a cornerstone to which the current practice of teaching and learning of engineering ethics education can be examined more critically, such that further improvements can be made to the existing curriculum that can help produce engineers that have strong moral and ethical characters.

This open access book explains how leading business organizations attempt to achieve the responsible and ethical use of artificial intelligence (AI) and other advanced information technologies. These technologies can produce tremendous insights and benefits. But they can also invade privacy, perpetuate bias, and otherwise injure people and society. To use these technologies successfully, organizations need to implement them responsibly and ethically. The question is: how to do this? Data ethics management, and this book, provide some answers. -/- The authors interviewed (...) and surveyed data ethics managers at leading companies. They asked why these experts see data ethics as important and how they seek to achieve it. This book conveys the results of that research on a concise, accessible way. -/- Much of the existing writing on data and AI ethics focuses either on macro-level ethical principles, or on micro-level product design and tooling. The interviews showed that companies need a third component: data ethics management. This third element consists of the management structures, processes, training and substantive benchmarks that companies use to operationalize their high-level ethical principles and to guide and hold accountable their developers. Data ethics management is the connective tissue makes ethical principles real. It is the focus of this book. -/- This book should be of use to organizations that wish to improve their own data ethics management efforts, legislators and policymakers who hope to build on existing management practices, scholars who study beyond compliance business behavior, and members of the public who want to understand better the threats that AI poses and how to reduce them.

Applications of quantum mechanics in the computational and information processing tasks is a recent research interest among the researchers. Certain operations which are impossible to achieve in the description of quantum mechanics are known as no-go theorems. One such theorem is no-splitting theorem of quantum states. The no-splitting theorem states that the information in an unknown quantum bit is an inseparable entity and cannot be split into two complementary qubits. In this work, we try to find out the class of (...) operators for which the splitting is possible in a probabilistic way. The work also aims to find the connection between the unitary operators and probabilistic splitting. (shrink)

As developed and developing countries move towards greater technological development in the 21st century, the need for engineers has increased substantially. Japan is facing the dilemma of insufficient engineers; therefore, the country has to rely on foreign workers. This problem may be resolved if there is a continuous effort to increase the number of women engineers, who currently represent only 1%–2% of engineers in Japan. In this study, the satisfaction level of the learning experience of Japanese female engineering students was (...) measured to determine its relationship with the students’ intention to choose engineering as their profession. Socio-cultural influences on the respondents’ intentions to pursue careers in the field were also studied. The findings revealed that learning experience was directly related to female students’ intention to pursue their career in engineering whereas socio-cultural values of a society have strong influences on students’ motivation to pursue careers in engineering in general. Additionally, some strategies are proposed to attract young girls to pursue engineering courses, as well as for current female engineering students to continue their studies and choose professions in the field as their career.

This article examines the series of historical events and government policy action that led to its emergence, the social implications of this growth and the challenges that India's education system faces in providing the manpower the IT industry needs to address the immense opportunities that lie ahead.

Quelle est la signification historique de l’implosion du néolibéralisme, moins de vingt ans après l’effondrement de l’Union soviétique? Une hypothèse troublante vient à l’esprit. On sait que l’URSS est parvenue au sommet de sa puissance dans les années 1970, juste avant de s’enfoncer dans une spirale de retranchement, de dérive et d’effondrement. Se pourrait-il, par une de ces bonnes vieilles ironies de l’histoire, qu’un revers de fortune comparable guette la superpuissance occidentale? Après tout, on peut voir une forme d’unité des (...) contraires dans l’opposition entre un capitalisme débridé et les économies industrielles planifiées de l’ancien COMECON.

Medicine is a science, and healing, an art. The right mix of a scientist and an artist is essential in a good physician. Clinical detachment is the balance between the scientist and the human. Good physicians are born; however, it is possible to cultivate the qualities. Gaining the patient's confidence is an art; a sense of humor can greatly help. Give a child respect and he becomes your friend. Death is inevitable, but a physician can help make it less agonizing. (...) A good physician is a philosopher, aware of the beauty of life, of his limitations and conscious of the power that controls us. (shrink)

We describe a general problem solving mechanism that is especially suited for performing a particular form of abductive inference, or best-explanation finding. A problem solver embodying this mechanism synthesizes composite hypotheses. It does so by by combining hypothesis parts as a means to the satisfaction of explanatory goals. In this way it is able to arrive at complex, integrated conclusions which are not pre-stored.The intent is to present a computationally-feasible, task-specific problem solver for a particular information processing task which is (...) nevertheless of very great generality. The task is that of synthesizing coherent composite explanatory hypotheses based upon a prestored, and possibly vast collection of hypothesis-generating “concepts”. The authors’ claim is nothing less than to have shown, in a new sense, and surpassing all other work in this area, how it is computationally possible for an agent to come to “know”, based upon the evidence of the case.

Red-2 is a computer program for red-cell antibody identification, a piece of "normal science". Abstracting from Red-2, a general problem solving mechanism is described that is especially suited for performing a form of abductive inference or best explanation finding.

The work addresses the question, 'How is science possible?' by showing how a simple but powerful (...) form of hypothesis synthesis is computationally feasible. (shrink)

The debate on sustainable globalized development rests on two clearly stated economic assumptions: that "development" proceeds, solely and inevitably, through industrialization and the proliferation of capital intensive high-technology, towards the creation of service sector economies; and that globalization, based on a neoliberal, capitalist, free market ideology, provides the only vehicle for such development. Sustainability, according to the proponents of globalized development, is merely a function of market forces, which will generate the solutions for all problems including the environmental dilemmas that (...) loom over the globe today. The social focus of globalized development is clearly the "individual" and the much-touted goal of development in the context of these debates, is the emancipation of the individual from want. This glorification of the individual, so characteristic of the Enlightenment, has defined all aspects of modernity, leading to approaches that are self-focused and that give little thought to the needs of society or even the social context. The increasing impoverishment of human life and the growing environmental degradation, however, provide a poignant counterpoint to this onrush of capital interests, demanding a reassessment of sustainability separate from the logic of industrialization and globalized development. This paper examines the unfolding of the logic of capitalism, which underlies the structure of the Rostowian model of development and the problems in the assumptions underlying today''s globalized development process. The evident impossibility of sustainability in the current growth-based market system leads to the examination of alternatives including a reflexive understanding of the choices and the inclusion of opportunity costs, related to the social, environmental and economic aspects of decision making. The integration of all factors of production into the logic of development provides a sustainable alternative to the current system. (shrink)

The unique properties of nanotechnology have made nanotechnology education and its related subjects increasingly important not only for students but for mankind at large. This particular technology brings educators to work together to prepare and produce competent engineers and scientists for this field. One of the key challenges in nanotechnology engineering is to produce graduate students who are not only competent in technical knowledge but possess the necessary attitude and awareness toward the social and ethical issues related to nanotechnology. In (...) this paper, a research model has been developed to assess Malaysian nanotechnology engineering students’ attitudes and whether their perspectives have attained the necesary objectives of ethical education throughout their programme of study. The findings from this investigation show that socio ethical education has a strong influence on the students’ knowledge, skills and attitudes pertaining to socio ethical issues related to nanotechnology.

Organizational climate has been linked to a variety of positive outcomes, including increased organizational success, lower employee turnover, higher job satisfaction, and enhanced employee and overall firm performance. The purpose of this paper is to explore similarities and differences in organizational climate across an emerging, a post-transitional, and a developed economy, more specifically focusing on India, Hungary, and Portugal. A comprehensive multi-dimensional measure of organizational climate is used, incorporating 17 scales across four quadrants: human relations, internal process, open systems, and (...) rational goal. The impact of certain key factors associated with the identified differences is explored across three levels: on the individual or within firm level, the group or between firm level, and, finally, on the global societal level, with relevant references made to the GLOBE project’s comprehensive cultural assessment. A total of 848 individuals participated in the study, representing 24 organizations. Despite the relative consistency in terms of the GLOBE study values corresponding to the three countries in the study, our results indicate variable trends and differential patterns, with India showing the most positive climate overall, and Portugal faring the worst. Our findings confirm the complexity associated with the concept of organizational climate, likely to be influenced by a variety of factors associated with the internal as well as the external environment. Implications for scholars as well as practitioners are discussed, with particular emphasis on those organizations entering novel cultures. (shrink)

Logopenic variant primary progressive aphasia is a neurodegenerative language disorder primarily characterized by impaired phonological processing. Sentence repetition and comprehension deficits are observed in lvPPA and linked to impaired phonological working memory, but recent evidence also implicates impaired speech perception. Currently, neural encoding of the speech envelope, which forms the scaffolding for perception, is not clearly understood in lvPPA. We leveraged recent analytical advances in electrophysiology to examine speech envelope encoding in lvPPA. We assessed cortical tracking of the speech envelope (...) and in-task comprehension of two spoken narratives in individuals with lvPPA and age-matched controls. Despite markedly reduced narrative comprehension relative to controls, individuals with lvPPA had increased cortical tracking of the speech envelope in theta oscillations, which track low-level features, but not delta oscillations, which track speech units that unfold across a longer time scale. This neural signature was highly correlated across narratives. Results indicate an increased reliance on acoustic cues during speech encoding. This may reflect inefficient encoding of bottom-up speech cues, likely as a consequence of dysfunctional temporoparietal cortex. (shrink)
