From an object-oriented perspective, this paper investigates the interdisciplinary aspects of problem representation as well the differences between representation of problems in the mind and that in the machine. By defining an object as a combination of a symbol-structure and its associated operations, it shows how the representation of problems can become related to control, which conducts the search in finding a solution. Different types of representation of problems in the machine are classified into four categories, and in a similar (...) way four distinct models are distinguished for the representation of problems in the mind. The concept of layered hierarchies, as the main theme of the object-oriented paradigm, is used to examine the implications of problem representation in the mind for improving the representation of problems in the machine.

University course timetabling is the scheduling of courses at different time slots in a university. The two important issues in this process are the allocation of all events to resources in a semester, and maximizing the satisfaction of common events among multiple departments. Accumulating evidences in university course timetabling problems suggest dividing the problem into several sub-problems. This study attempted to investigate the appropriateness of using the genetic algorithm and the imperialist competitive algorithm. The proposed technique consists of two steps: (...) using the proposed manipulated GA for solving the timetabling problem of each department, and eliminating the interference of common events among multiple departments and satisfying the hard and soft constraints by using ICA. Finally, a report on the efficiency of the methodology used in this study was obtained from the University of Tabriz in Iran and University of Udine in Italy. In this paper, the results are revealed in two ways: reduction in the problems due to shrinking of the database and solving of the problems in parallel and solving the different parts of the problem by using various criterion results, increasing the common events satisfaction in that sub-problem. Eventually, the proposed model provided successful satisfaction of the hard constraints in <700 iterations with GA and elimination of interference in 40 iterations with ICA in most of the cases.

At the intersection of social and virtue epistemology lies the important, yet so far entirely neglected, project of articulating the social dimensions of epistemic virtues. Perhaps the most obvious way in which epistemic virtues might be social is that they may be possessed by social collectives. We often speak of groups as if they could instantiate epistemic virtues. It is tempting to think of these expressions as ascribing virtues not to the groups themselves, but to their members. Adapting Margaret Gilbert's (...) arguments against individualist accounts of collective beliefs, I show that individualist accounts of group virtues are either too weak or too strong. I then formulate a non-individualist account modeled after Gilbert's influential account of collective beliefs. A crucial disanalogy between collective traits and beliefs, I argue, makes the success of this model unlikely. I conclude with some questions with which the future work on collective epistemic virtues should engage. (shrink)

The relationship between the photographic and optical images and time has been the subject of great deal of debate. Despite their differences, what many of these considerations have in common is their focus on the receiver, whether mechanical, biological, social or the memory and imagination of the observer. My aim here is to shift the emphasis from the receiver to the object or vista that is photographed or viewed and to explore how the constraints implied by our modern understanding of (...) the Universe, concerning space and time, impact on the way we perceive photographic and optical images. Viewed from this perspective, photographs can be treated as light projections of sections of the four-dimensional observable world onto two-dimensional spatial photographic or viewing surfaces. I shall show that despite the severe reduction that such projections imply, these modern considerations have the important consequence of bestowing a complex temporality upon optical images, including photographs. This realization dramatically changes the way we view photographs. I give examples of this rich temporality through considerations of terrestrial images – and more significantly images of the Sky, where these temporal effects are far more pronounced. (shrink)

The recent literature on epistemic virtues advances two general projects. The first is virtue epistemology, an attempt to explicate key epistemic notions in terms of epistemic virtue. The second is epistemic virtue theory, the conceptual and normative investigation of cognitive traits of character. While a great deal of work has been done in virtue epistemology, epistemic virtue theory still languishes in a state of neglect. Furthermore, the existing work is non-naturalistic. The present paper contributes to the development of a naturalistic (...) epistemic virtue theory by presenting a virtue-theoretic evaluation of need for cognition as informed by the relevant psychological studies.

Scientific study of dreams requires the most objective methods to reliably analyze dream content. In this context, artificial intelligence should prove useful for an automatic and non subjective scoring technique. Past research has utilized word search and emotional affiliation methods, to model and automatically match human judges’ scoring of dream report’s negative emotional tone. The current study added word associations to improve the model’s accuracy. Word associations were established using words’ frequency of co-occurrence with their defining words as found in (...) a dictionary and an encyclopedia. It was hypothesized that this addition would facilitate the machine learning model and improve its predictability beyond those of previous models. With a sample of 458 dreams, this model demonstrated an improvement in accuracy from 59% to 63% on the negative emotional tone scale, and for the first time reached an accuracy of 77% on the positive scale.

While there is general agreement about the list of epistemic virtues, there has been much controversy over what it is to be an epistemic virtue. Three competing theories have been offered: evaluational externalism, evaluational internalism, and mixed theories. A major problem with internalism, the focus of this paper, is that it disconnects the value of epistemic virtue from actual success in the real world (the Disconnection Problem). Relying on a novel thesis about the relation of “trying” and “exercise of virtue,” (...) James Montmarquet (1993; 2000) has offered, to my knowledge, the only solution to this problem. In this paper, I evaluate this solution by deriving from it an important implication and arguing that, if examined in the light of the recent work on self-control in philosophy and psychology, this implication proves problematic. I conclude by drawing a general lesson about the prospects of internalism and suggesting that in the absence of a satisfactory solution to the disconnection problem, externalism and mixed theories become more attractive.

Herbert Simon viewed innovation as a particular type of problem-solving behavior that entails refocus of attention and search for alternatives outside the existing domain of standard operations. This exploration outside of standard routines involves heuristic-based discovery and action, such as satisficing search for information and options. In our observations on the innovation process, we focus on knowledge generation. We propose viewing the process of generating knowledge—when knowledge is sufficient to instigate action, but not necessarily enough to eliminate the uncertainty of (...) the situation—as a heuristic process. Because many personal and organizational decisions are acted upon in the presence of some degree of uncertainty, we argue that heuristics structure the way in which information is processed innovatively. We provide a catalogue of instances in business decision making. (shrink)

We consider the domain of applicability of general relativity (GR), as a classical theory of gravity, by considering its applications to a variety of settings of physical interest as well as its relationship with real observations. We argue that, as it stands, GR is deficient whether it is treated as a microscopic or a macroscopic theory of gravity. We briefly discuss some recent attempts at removing this shortcoming through the construction of a macroscopic theory of gravity. We point out that (...) such macroscopic extensions of GR are likely to be nonunique and involve non-Riemannian geometrical frameworks. (shrink)

In this comment, we will focus on Greco’s brief for agent reliabilism in preference to simple reliabilism. Agent reliabilism differs from simple reliabilism primarily in requiring, not merely belief that results from a reliable process, but belief grounded in stable dispositions that make up the subject’s character.

In this essay, Frederick Schmitt and Reza Lahroodi explore the value of curiosity for inquiry and knowledge. They defend an appetitive account of curiosity, viewing curiosity as a motivationally original desire to know that arises from having one’s attention drawn to the object and that in turn sustains one’s attention to it. Distinguishing curiosity from wonder, the authors explore several sources of the epistemic value of curiosity. First, curiosity is tenacious: curiosity whether a proposition is true leads to curiosity (...) about related issues, thereby deepening our knowledge. Second, it is to some extent biased in favor of topics in which we already have a practical or epistemic interest. Third, and most important, curiosity is largely independent of our interests: it fixes our attention on objects in which we have no antecedent interest, thereby broadening our knowledge. Schmitt and Lahroodi elucidate the value of curiosity by outlining its role in levels of development — an approach indebted to John Dewey’s explanation of the value of curiosity. Finally, they raise some questions about the implications of their account for educational practice. (shrink)

In this article, we argue that although Bohr's version of the Copenhagen interpretation is in line with several key elements of logical positivism, pragmatism is the closest approximation to a classification of the Copenhagen interpretation, whether or not pragmatists directly influenced the key figures of the interpretation. Pragmatism already encompasses important elements of operationalism and logical positivism, especially the liberalized Carnapian reading of logical positivism. We suggest that some elements of the Copenhagen interpretation, which are in line with logical positivism, (...) are also supported by pragmatism. Some of these elements are empirical realism, fallibilism, holism, and instrumentalism. However, pragmatism goes beyond logical positivism in espousing some other key elements of the Copenhagen interpretation, though imperfectly, such as the correspondence principle, complementarity, and indeterminism.

Given the evolution of the public health and the changes from the phenomenon of globalization, this area has encountered new ethical challenges. In order to find a coherent approach to address ethical issues in PH policy, this study aimed to identify the evolution of public health ethics frameworks and the main moral values and norms in PH practice and policy. According to the research questions, a systematic search of the literature, in English, with no time limit was performed using the (...) main keywords in databases Web of Science and PubMed. Finally, the full text of 56 papers was analyzed. Most of the frameworks have common underpinning assumptions and beliefs, and the need to balance PH moral obligation to prevent harm and health promotion with respect for individual autonomy has been specified. As such, a clear shift from liberal values in biomedical ethics is seen toward the community’s collective values in PHE. The main moral norms in PH practice and policy included protecting the population against harm and improving PH benefits, utility and evidenced-based effectiveness, distributive justice and fairness, respect for all, privacy and confidentiality, solidarity, social responsibility, community empowerment and participation, transparency, accountability and trust. Systematic review of PHE frameworks indicates utilization of the aforementioned moral norms through an practical framework as an ethical guide for action in the PH policy. The validity of this process requires a systematic approach including procedural conditions. (shrink)

There are two main theories of ontological commitment: the quantifier view, and the truthmaker view. Since there are some truths that apparently commit us to certain entities, but actually do not, any ontological commitment theory must also contain an ontological reduction theory. Advocates of the quantifier view propose the paraphrasing method of reduction, while advocates of the truthmaker view propose the supervenience method. In this paper, after a brief discussion of the quantifier view, I propose a modified version of truthmaker-based (...) ontology, and show that a plausible account of the supervenience method can be deduced from my version. I then show that the supervenience method could explain why the paraphrasing method is successful, albeit that there are some cases in which the supervenience method works but the paraphrasing method does not, or so it seems prime facie. I also argue that according to the truthmaker view we must accept composite objects as something over and above the particles which constitute them. (shrink)

Armstrong appeals to the existence of totalities in order to solve the problem of negative truths. The totality of first-order states of affairs is a truthmaker for all negative truths, but it involves things which are irrelevant to many such truths. To solve this problem, Armstrong claimed that negative truths have minimal truthmakers which usually consist in totalities smaller than the totality of first-order states of affairs. Merricks objects to this claim by arguing that given Armstrong’s definition of minimal truthmakers, (...) the totality of first-order states of affairs is a minimal truthmaker for every negative truth. In this article, I respond to Merricks’s objection. I will first show that the definition of minimal truthmakers that he proposes is not plausible. However, Merricks’s objection, I will argue, also works on the standard definition of minimal truthmakers. I will then show that for independent reasons, the standard definition should be revised, and, given my revised definition, Merricks’s objection fails. (shrink)

To illuminate the problems and perspectives of water management in Iran and comparable arid Middle East and North Africa countries, three paradigms can be distinguished: the traditional, the industrial and the reflexive paradigm. Each paradigm is characterised by its key technical system, its main social institution and its ethico-religious framework. Iran seems to be in a state of transition from the 'hydraulic mission' of industrial modernity to a more reflexive approach to water management. This article sketches the contours of the (...) emerging paradigm: a complementary system of traditional and modern methods of water provision, a participatory water resources management and a 'post-mechanistic' ethico-religious framework.

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention, working memory, and episodic memory retrieval. Several recent fMRI studies have also reported fronto-parietal activity during conscious visual perception. A major goal of this review was to assess the degree of anatomical overlap among activation patterns associated with these four functions. A second goal was to shed light on the possible cognitive relationship of processes that relate to common brain activity across functions. For all reviewed functions we (...) observed a consistent and overlapping pattern of brain activity. The overlap was most pronounced for the bilateral parietal cortex , and dorsolateral prefrontal cortex . The common fronto-parietal activity will be discussed in terms of processes related to integration of distributed representations in the brain. (shrink)

There are many studies conducted on recommendation systems, most of which are focused on recommending items to users and vice versa. Nowadays, social networks are complicated due to carrying vast arrays of data about individuals and organizations. In today’s competitive environment, companies face two significant problems: supplying resources and attracting new customers. Even the concept of supply-chain management in a virtual environment is changed. In this article, we propose a new and innovative combination approach to recommend organizational people in social (...) networks based on organizational communication and SCM. The proposed approach uses a hybrid strategy that combines basic collaborative filtering and demographic recommendation systems, using data mining, artificial neural networks, and fuzzy techniques. The results of experiments and evaluations based on a real dataset collected from the LinkedIn social network showed that the hybrid recommendation system has higher accuracy and speed than other essential methods, even substantially has eliminated the fundamental problems with such systems, such as cold start, scalability, diversity, and serendipity.

Knowledge management is important in the construction industry, but there is a dramatic gap between rhetoric and reality, highlighting mistaken expectations of technology. We report on a case study of a major construction company. The UK construction industry, with scarce academic qualifications, and limited use of IT, depends on knowledge sharing, and, crucially, on tacit knowledge. Economic crisis presents particular problems, and recent trends in work organization have far-reaching implications. The industry depends on human knowledge, with limited systems support. A (...) shared concern for health and safety provides the surest guarantee of sustainability of both knowledge and the company. (shrink)

Patient advocacy has been a topic of much discussion in the nursing literature for a number of decades. Ambiguities remain, however, concerning definitions of advocacy in nursing. This qualitative grounded theory-type study aimed to inquire into the meaning of patient advocacy from Iranian nurses' perspective. A purposive sample of 24 nurses (staff nurses, head nurses and supervisors) working in a large university hospital in Tehran was used. Data were collected using in-depth semistructured interviews and reflective diaries kept by the participants. (...) The data were analyzed using elements of Strauss and Corbin's' approach. Advocacy was defined by the participants as: informing and educating; valuing and respecting; supporting; protecting; and promoting continuity of care for patients. The participants also believed that advocacy could take place only if there was respect for patients' individuality and their inherent human dignity. Many of the descriptions given by the participants are consistent with previous research in this area and represent a comprehensive account of their perceptions of patient advocacy. (shrink)

In addition to their historical interest, cultural heritage buildings are valuable because they contribute significantly to the economy by providing key attractions at a time when tourism and leisure are major industries. The need for preserving historical constructions is thus not only a cultural requirement, but also an economical and developmental demand. Herein, among different Iranian heritage buildings, pigeon towers, or dovecotes, are of a great importance. Hundreds of dovecotes, dating largely to the Safavid period, dot the fields in the vicinity of Isfahan. On the other hand, valleys formed by creeks in central parts of Anatolia seem to have offered suitable environments for ancient settlements. Cappadocia region and two valleys nearby the town of Gesi accommodate a number of villages surrounded by hundreds of dove cotes in different types. This paper investigates different types of dovecotes in Iran plateau and Central Anatolia, Turkey. The results show there is a fundamental difference between the structures of dovecotes in these two countries. However, ancient dovecotes in Iran and Central Anatolia can be considered good examples of 'architecture without architects' or ' spectacular vernacular architecture'. Master builders who designed and constructed these buildings for such a simple function, created impressive forms without much pretension and bringing forth the tectonic aspects of the art of architecture.

Our overall evidence illustrates that, contrary to this (...) view, SMEs report social information regardless of their financial constraints, most likely in the same manner as large companies do, because they realise the significance of social reporting in establishing and retaining their corporate reputation.

Ethical maturity is a great concern to all educators, firms, and investors across the globe. This research surveyed 448 citizens, managers and employees in Iran to measure their Personal Business Ethics Scores (PBES) to see if age, education, management experience, and government work experience make a difference in making more ethical decisions. This study contributes to the theory of moral development across the Iranian culture as it is the first known study using this method. The results suggest that education and (...) more years of government work experience make a difference in the moral maturity of respondents. This study confirms that the ethical maturity of respondents is enhanced either through the authoritarian regime or socialization with Islamic values. Kohlberg’s moral development theory regarding ethical maturity is partially supported since those with more years of experience in government and more formal education have higher business ethics scores. Implications are discussed. (shrink)

In other words, cascading the strategic plan into a form of an operational program is a key to organizational success. Strategic success will be achieved if the right strategies are cascaded in the organization rightly. The (...) purpose of this research is to provide a framework for the strategic plan cascading into steps and an operational process to facilitate its implementation in the organization. For this purpose, the mission-focused organizations were considered. These organizations go beyond profitability and following the implementation of strategies and action plans are in searching to fulfill the mission for which it is designed and developed. Here, the ultimate goal is to achieve a designated and defined mission. This qualitative analytic research is seeking to provide a framework for cascading organizational strategies using a scientific and applied approach. After presenting the research's conceptual framework, in order to test and analysis the model, using experts' viewpoints through a questionnaire required data was gathered and analyzed. The results and findings of this research show that for the implementation of the developed strategies, a systematic and stepwise model is needed that consists of several stages: the formulation of strategies, the prioritization of strategies with strategic tools, comparative studies to find the transformation of the strategy into the program, and finally the design of the operational program and its quantitative objectives and measures.

Having entered into the problem structuring methods, system dynamics (SD) is an approach, among systems’ methodologies, which claims to recognize the main structures of socio-economic behaviors. However, the concern for building or discovering strong philosophical underpinnings of SD, undoubtedly playing an important role in the modeling process, is a long-standing issue, in a way that there is a considerable debate about the assumptions or the philosophical foundations of it. In this paper, with a new perspective, we have explored theory of (...) knowledge in SD models and found strange similarities between classic epistemological concepts such as justification and truth, and the mechanism of obtaining knowledge in SD models. In this regard, we have discussed related theories of epistemology and based on this analysis, have suggested some implications for moderating common problems in the modeling process of SD. Furthermore, this research could be considered a reword of system dynamics modeling principles in terms of theory of knowledge. (shrink)

Reza Akbari Solving moral conflicts entails a decision-making process. So any suggested approach to moral conflicts is included in the domain of practical rationality. The practical rationality is based on theoretical rationality. Both the theoretical and practical rationality have a realistic kind of approach and an idealistic kind of approach. In the theoretical rationality, the idealistic approaches demand certainty in a strict sense, following epistemic guidelines; and in the practical rationality, they demand the best possible choice. Nevertheless, there are (...) some difficulties with the idealistic approaches. Concerning the realistic approaches, we can gain access to two truths: First, each situation is an individual circumstance and each person has certain epistemic features, and so it is not possible to present general, universalizable solutions to conflicts even in a particular scope. Second, the acceptance of some propositions is a voluntary act, and so cognitive space and previous beliefs of any individual have a role in the acceptance of a belief and the following universalizations. By attention to extensive emphasis of the religion on moral doctrines, it can be said that religious education through practical patterns has a positive role in solving moral conflicts. (shrink)

Most of research on fostering ethical behavior among students has taken place in US and Europe. This paper seeks to provide additional information to both educators and organizations about the ethical perceptions of Iranian students by investigating the effect of gender on students’ ethical behavior. The authors developed and administered a quantitative questionnaire to a sample of 203 individuals currently pursuing accredited degrees at one of the public universities in Iran. Statistical analysis revealed that male students have a significantly less (...) ethical behavior in three factors (selfishness, academic cheating and computer ethics) than female students. While the topic of students’ ethical behavior and its relationship with gender has been extensively studied before, there have been contrasting findings by different researchers. This paper is among the very few first researches conducted among Iranian university students to investigate the effects of gender on students’ ethical behavior under the four categories of violation of school regulations, selfishness, academic cheating, and computer ethics, hence making an important contribution to the ethics literature on the developing countries, since the study was conducted in Iran.
