BackgroundOrgan donation has become one of the most effective ways to save lives and improve the quality of life for patients with end-stage organ failure. No previous studies have investigated the preferences for the different consenting options for organ donation in Egypt. This study aims to assess Egyptians’ preferences regarding consenting options for posthumous organ donation, and measure their awareness and acceptance of the Egyptian law articles regulating organ donation.MethodsA cross sectional study was conducted among 2743 participants over two years. (...) Each participant was required to rank eleven consenting options from 1 to 11, and to report his awareness and acceptance of the seven articles of the Egyptian law of organ donation.Results47% of the participants expressed willingness to donate their organs after death. This percentage increased to 78% when consenting options were explained to participants. “Informed consent by donor only” was the most preferred type of consent for one third of respondents. Awareness of the law articles regulating organ donation was relatively low ranging from 56% to 23%.ConclusionCurrently, around half of the Egyptian population agree to posthumous organ donation. This percentage could be increased significantly by raising the awareness about how the process of donation could be regulated and how the patient’s right of decision could be protected. (shrink)

University based academic Research Ethics Boards (REB) face the particularly difficult challenge of trying to achieve representation from a variety of disciplines, methodologies and research interests. Additionally, many are currently facing another decision – whether to have students as REB members or not. At Ryerson University, we are uniquely situated. Without a medical school in which an awareness of the research ethics review process might be grounded, our mainly social science and humanities REB must also educate and foster awareness of (...) the ethics review process throughout the academic community. Our Board has had and continues to have students as active members. While there are challenges to having students as Board members, these are clearly outweighed by the advantages, for both the academic community and the future of ethically sound research in the social sciences and humanities. Moreover, the challenges are often based on misconceptions and can be easily overcome through increased education and understanding of the research ethics review process by the academic community at large. The purpose of this paper is to describe and discuss the experiences, advantages and challenges of having students as REB members. The advantages of having students as REB members include the following: (1) Students are the proposed participants in many of our reviewed protocols and student members may illuminate unique issues of participation. (2) Students are active and highly engaged members of the REB. (3) Having students on the REB enhances awareness of research ethics within the University. (4) Student REB members have an opportunity to mentor other students and provide leadership for both undergraduate and graduate students. (5) Students are more vigorously recruited than faculty members and often apply for student positions with enthusiasm and preparation. (6) In creating an atmosphere of excellence in research, engaging students at the beginning of their research career will help in creating tomorrow’s leaders in research and research ethics. The challenges of having students as REB members include the following: (1) Faculty members may be uneasy regarding the prospect of students reviewing protocols. (2) Faculty members may be concerned about confidentiality and respect with students reviewing faculty research protocols. (3) There may be an increased burden for students who serve as members on an REB. (4) There is concern that students will offer less continuous service to the REB. (5) There is a common misconception that students do not have the experience to carry out ethical reviews. While there are challenges from faculty members and others regarding having students as REB members, these challenges are often based on misconceptions about the nature of the REB work and the ethics review process in general. These challenges are also often based on the misconception of the ethics review process as one of peer review and evaluation, instead of a community-based and inclusive process. Having student members is a long-term strategy for both overcoming the misconceptions of the REB as a “necessary evil” and for fostering an awareness of the imperative for ethically sound research in the social sciences and humanities.

Summary Background The principle of maximization, which roughly means that we should save more lives and more years of life, is usually taken for granted by the health community. This principle is even more forceful in crises like the COVID-19 pandemic, where we have scarce resources which can be allocated only to some patients. However, the standard consequentialist version of this principle can be challenging particularly when we have to reallocate a resource that has already been given to a patient. (...) -/- Methodology Engaging in thought experiments, conceptual analysis, providing counterexamples, and appealing to moral intuitions, we challenge the standard consequentialist version of the maximization principle and make a case for adopting an alternative deontological version. -/- Discussion In certain cases, the standard consequentialist version of the maximization principle is shown to yield intuitively immoral results. The deontological version of this principle is preferable because it can retain the merits of the standard consequentialist version without falling prey to its problems. -/- Conclusion Compared to the standard consequentialist version, the deontological version of the maximization principle can better guide the ethical decisions of the health community, even in cases where we face a scarcity of resources.

Background: Falls in older adults are a major public health problem. White matter hyperintensities are highly prevalent in older adults and are a risk factor for falls. In the absence of a cure for WMHs, identifying potential strategies to counteract the risk of WMHs on falls are of great importance. Physical activity is a promising countermeasure to reduce both WMHs and falls risk. However, no study has yet investigated whether PA attenuates the association of WMHs with falls risk. We hypothesized (...) that PA moderates the association between WMHs and falls risk.Methods: Seventy-six community-dwelling older adults aged 70–80 years old were included in this cross-sectional study. We indexed PA using the Physical Activity Score for the Elderly Questionnaire. Falls risk was assessed using the Physiological Profile Assessment, and WMH volume was determined by an experienced radiologist on T2-weighted and PD-weighted MRI scans. We first examined the independent associations of WMH volume and PASE score with PPA. Subsequently, we examined whether PASE moderated the relationship between WMH volume and PPA. We plotted simple slopes to interpret the interaction effects. Age, sex, and Montreal Cognitive Assessment score were included as covariates in all models.Results: Participants had a mean age of 74 years and 54 were female. Forty-nine participants had a Fazekas score of 1, 19 had a score of 2, and 6 a score of 3. Both PASE and WMH volume were each independently associated with PPA score. The interaction model indicated that PASE score moderated the association between WMH volume and PPA, whereby higher PASE score attenuated the association between WMHs and falls risk.Conclusion: PA is an important moderator of falls risk. Importantly, older adults with WMH can reduce their risk of falls by increasing their PA. (shrink)

The extended Church-Turing thesis posits that any computable function can be calculated efficiently by a probabilistic Turing machine. If this thesis held true, the global effort to build quantum computers might ultimately be unnecessary. The thesis would however be strongly contradicted by a physical device that efficiently performs a task believed to be intractable for classical computers. BosonSampling - the sampling from a distribution of n photons undergoing some linear-optical process - is a recently developed, and experimentally accessible example of (...) such a task [1].

Argumentation has remained under-researched in studies analyzing academic journal publications despite its importance in academic writing. This paper reports a study in which we investigated stereotypical argumentative trends, lexico-grammatical features, and interactional metadiscourse markers in 354 research article free-standing discussion sections from the journal of ESP over forty years. The field of ESP was chosen because of its maturity, which has given substance to a dynamic ground for arguments. We drew on the pragma-dialectical approach to analyzing argumentations in the corpus. (...) Findings indicated that due to the argumentative nature of the discussion section, certain argumentative trends recurred more often. The analysis of the lexico-grammatical features and metadiscourse markers of the standpoints also showed patterns of variability over time. The study concludes that it is imperative to incorporate relevant facets from various argumentation models to construct a comprehensive argumentation theory and gain deeper insights into argumentation in academic writing.

This study investigates the effect of country-level emancipative forces on corporate gender diversity around the world. Based on Welzel’s theory of emancipation, we develop an emancipatory framework of board gender diversity that explains how action resources, emancipative values and civic entitlements enable, motivate and encourage women to take leadership roles on corporate boards. Using a sample of 6390 firms operating in 30 countries around the world, our results show positive single and combined effects of the framework components on board gender (...) diversity. Our research adds to the existing literature in a twofold manner. First, our integrated framework offers a more encompassing, complete and theoretically richer picture of the key drivers of board gender diversity. Second, by testing the framework empirically, we extend the evidence on national drivers of board gender diversity. (shrink)

With the rapid growth of informatics systems’ technology in this modern age, the Internet of Things (IoT) has become more valuable and vital to everyday life in many ways. IoT applications are now more popular than they used to be due to the availability of many gadgets that work as IoT enablers, including smartwatches, smartphones, security cameras, and smart sensors. However, the insecure nature of IoT devices has led to several difficulties, one of which is distributed denial-of-service (DDoS) attacks. IoT (...) systems have several security limitations due to their disreputability characteristics, like dynamic communication between IoT devices. The dynamic communications resulted from the limited resources of these devices, such as their data storage and processing units. Recently, many attempts have been made to develop intelligent models to protect IoT networks against DDoS attacks. The main ongoing research issue is developing a model capable of protecting the network from DDoS attacks that is sensitive to various classes of DDoS and can recognize legitimate traffic to avoid false alarms. Subsequently, this study proposes combining three deep learning algorithms, namely recurrent neural network (RNN), long short-term memory (LSTM)-RNN, and convolutional neural network (CNN), to build a bidirectional CNN-BiLSTM DDoS detection model. The RNN, CNN, LSTM, and CNN-BiLSTM are implemented and tested to determine the most effective model against DDoS attacks that can accurately detect and distinguish DDoS from legitimate traffic. The intrusion detection evaluation dataset (CICIDS2017) is used to provide more realistic detection. The CICIDS2017 dataset includes benign and up-to-date examples of typical attacks, closely matching real-world data of Packet Capture. The four models are tested and assessed using Confusion Metrix against four commonly used criteria: accuracy, precision, recall, and F-measure. The performance of the models is quite effective as they obtain an accuracy rate of around 99.00%, except for the CNN model, which achieves an accuracy of 98.82%. The CNN-BiLSTM achieves the best accuracy of 99.76% and precision of 98.90%. (shrink)

Twitter is a virtual social network where people share their posts and opinions about the current situation, such as the coronavirus pandemic. It is considered the most significant streaming data source for machine learning research in terms of analysis, prediction, knowledge extraction, and opinions. Sentiment analysis is a text analysis method that has gained further significance due to social networks’ emergence. Therefore, this paper introduces a real-time system for sentiment prediction on Twitter streaming data for tweets about the coronavirus pandemic. (...) The proposed system aims to find the optimal machine learning model that obtains the best performance for coronavirus sentiment analysis prediction and then uses it in real-time. The proposed system has been developed into two components: developing an offline sentiment analysis and modeling an online prediction pipeline. The system has two components: the offline and the online components. For the offline component of the system, the historical tweets’ dataset was collected in duration 23/01/2020 and 01/06/2020 and filtered by #COVID-19 and #Coronavirus hashtags. Two feature extraction methods of textual data analysis were used, n-gram and TF-ID, to extract the dataset’s essential features, collected using coronavirus hashtags. Then, five regular machine learning algorithms were performed and compared: decision tree, logistic regression, k-nearest neighbors, random forest, and support vector machine to select the best model for the online prediction component. The online prediction pipeline was developed using Twitter Streaming API, Apache Kafka, and Apache Spark. The experimental results indicate that the RF model using the unigram feature extraction method has achieved the best performance, and it is used for sentiment prediction on Twitter streaming data for coronavirus.

The paper analyses the behaviour of French corporate executives towards the adoption of Internet voting at shareholders’ general meetings. The research extends the studies of legitimation strategies and institutional theory to a new topic and a new instrument of corporate governance. Taking a qualitative approach, the paper examines the particular case of a technology that is adopted by a company for the benefit of its shareholders. It contributes theoretically by showing how executives respond to institutional pressures when responding could affect (...) their own interests. The findings illustrate the nature and extent of six legitimation strategies used by executives when confronted by Internet shareholder voting. Interestingly, the results highlight the prevalence of manipulation and coalition-building strategies. A typology of adoption behaviours is also proposed. Interestingly, the results show how executives worry about the risk that Internet voting may lead to a loss of control. Overall, the paper argues that the relationship between shareholders and executives with regard to corporate governance is partially reversed by the adoption of Internet voting. Some theoretical and managerial implications of the paper for the literature on corporate governance and business ethics are discussed. (shrink)

The concept of reincarnation is believed to be the rebirth of humans in the world as a form of part of their life journey in accordance with their actions during life with various forms of reincarnation—including being able to be reborn as humans or animals. This article aims to discuss Mullā Ṣadrā’s eschatological thoughts, especially his criticism of the concept of reincarnation which has been believed by Hindus and Buddhists. Reincarnation is a topic of discussion for philosophers including Islamic philosophers (...) in discussing the spirit, soul, body, death, and resurrection. Ṣadrā’s rejection of the concept of reincarnation is found in one of his main works entitled al-Asfār al-Arba‘ah. By using analytical and descriptive methods, it was concluded that Mullā Ṣadrā rejected the concept of reincarnation with his five philosophical arguments, including the natural unity argument, the material and form needs argument, Kawn and Fasād’s argument, the vacuum argument, and the argument with five premises. These philosophical arguments are based on Ṣadrā’s main philosophical principle, namely the substantial movement of the soul. Even though he rejects the concept of reincarnation, Ṣadrā still believes in the resurrection of the soul and body after death, which will continue the journey towards the highest perfection in the afterlife.

This study examined the relationship between urban culture and street vending. Prior research on this topic is limited and inconclusive. Therefore, we have proposed an integrated model to test the positive effect of urban culture on street vending using multiple mediations of consumption patterns, resistance, and microfinance. We tested a sample of 425 responses that reflect the public opinion in Baghdad, Iraq. These responses were collected between September and November 2018. A partial least squares–based structural equation modeling is employed to (...) test the validity of measurement models and the significance of the entire structural model, predictive power, and mediation analysis. We found that resistance mediates the effect of urban culture on street vending; low-income consumption and resistance sequentially mediate the effect of urban culture on street vending, while resistance mediates the effect of a lack of microfinance on street vending. The direct impact of culture on street vending is not significant, and a lack of microfinance positively influences the pervasiveness of trading on streets. This study contributes to the extant literature as it proposed and tested a novel and comprehensive model to analyze the relationship between urban culture and street vending, simultaneously examining the effects of culture, consumption, resistance, and microfinance on street vending.

Islamic banking is based on moral foundations that make it distinct from conventional banking. Some argue that because of its foundation in Islam, Islamic banking may represent a more morally appealing alternative. Yet, evidence shows that this is not the case. Indeed, the current practice of Islamic banking has not been able to achieve its goals which are based on Islam's moral values: to enhance justice, equitability, and social well-being. This essay examines the extent to which Islamic banking is ethical (...) and concludes that the practice of the industry does not seem to be de facto ethical from the Islamic perspective of ethical values. It only consists in trading the same instruments of conventional banks without genuinely enforcing Islam's ethical vision. The practice of Islamic banking misrepresents Islam and does not contribute to solving social problems. The interaction between maqasid al-shari᾽a and qiyās provides a supplementary tool for interpreting the failure of the prior in terms of the practical misuse of the latter by Islamic banks. This essay provides an interpretive approach to the current debate about why Islamic banking has failed and suggests ways to move cautiously in the future. (shrink)

Parity games are combinatorial representations of closed Boolean μ-terms. By adding to them draw positions, they have been organized by Arnold and Santocanale [3] and [27] into a μ-calculus whose standard interpretation is over the class of all complete lattices. As done by Berwanger et al. [8] and [9] for the propositional modal μ-calculus, it is possible to classify parity games into levels of a hierarchy according to the number of fixed-point variables. We ask whether this hierarchy collapses w.r.t. the (...) standard interpretation. We answer this question negatively by providing, for each n≥1, a parity game Gn with these properties: it unravels to a μ-term built up with n fixed-point variables, it is not semantically equivalent to any game with strictly less than n−2 fixed-point variables.

This article investigates the efficacy of a form of electoral innovation unique to the island-state of Singapore, the Nominated Member of Parliament scheme, and its impact on democratic governance, in light of the changing political landscape. A comparative perspective will be employed and broader conclusions on electoral engineering will be reached, especially for democratizing countries. Contrary to conventional scholarly wisdom, I argue that the NMP scheme can actually boost democratic representation in the country, considering the changing political landscape in the (...) state previously dominated by a hegemonic party. This is via two ways: firstly, NMPs could better represent the voices of the people at the margins of society and, secondly, they could be better positioned to raise issues that are deemed too to be raised by opposition parties. NMPs can enhance democratic governance by promoting deliberation, accountability, and representation. (shrink)

This study presents the fundamental concepts and technical details of a U-model-based control system design framework, including U-model realisation from classic model sets, control system design procedures, and simulated showcase examples. Consequently, the framework provides readers with clear understandings and practical skills for further research expansion and applications. In contrast to the classic model-based design and model-free design methodologies, this model-independent design takes two parallel formations: it designs an invariant virtual controller with a specified closed-loop transfer function in a feedback (...) control loop and it determines the real controller output by resolving the inverse of the plant U-model. It should be noted that this U-control provides a universal control system design platform for many existing linear/nonlinear and polynomial/state-space models and it complements many existing design approaches. Simulation studies are used as examples to demonstrate the analytically developed formulations and guideline for potential applications. (shrink)

Abstract The purpose of this paper is twofold: (i) we will argue that formal semantics might have faltered due to its failure in distinguishing between two fundamentally very different types of concepts, namely ontological concepts, that should be types in a strongly-typed ontology, and logical concepts, that are predicates corresponding to properties of, and relations between, objects of various ontological types; and (ii) we show that accounting for these differences amounts to a new formal semantics; one that integrates lexical and (...) compositional semantics in one coherent framework and one where formal semantics is embedded with a strongly typed ontology; an ontology that reflects our commonsense knowledge of the world and the way we talk about it in ordinary language. We will show how in such a framework a number of challenges in the semantics of natural language are adequately and systematically treated. (shrink)

The fault ride-through capability and fault current issues are the main challenges in doubly fed induction generator- based wind turbines. Application of the bridge-type fault current limiter was recognized as a promising solution to cope with these challenges. This paper proposes a nonlinear sliding mode controller for the BFCL to enhance the FRT performance of the DFIG-based WT. This controller has robust performance in unpredicted voltage sag level and nonlinear features. Theoretical discussions, power circuit, and nonlinear control consideration of the (...) SMC-based BFCL are conducted, and then, its performance is verified through time-domain simulations in the PSCAD/EMTDC environment. To reduce the chattering phenomenon and decrease the reaching time, it used the exponential reaching law for designed SMC. Also, the SMC-based BFCL performance is compared with the conventional and PI controller-based BFCL for both symmetrical and asymmetrical short-circuit faults. Simulation results reveal that the SMC-based BFCL provides better performance compared with the conventional and PI controller-based BFCL to enhance the FRT. (shrink)

Street vendors are prominent on public streets and in traditional markets in most developing countries. They raise significant problems for public authorities, residents, pedestrians, and formal retailers. Their informal business is problematic, leading to conflicts and sometimes violence. Moreover, unlicensed street vendors employ children and women and are accused of counterfeiting and drug trading. However, they participate in reducing poverty and unemployment. The current data article aims to formulate a public perception on the problematic issue of street vending pervasiveness by (...) describing a survey dataset on street vending and its main driving factors. Street vending has traditionally be examined by linking it with one or more determinants; thus, the dataset covers poverty, lack of education, immigration, unemployment, urban culture, low-income consumption, resistance, and lack of microfinance as latent constructs. Five measurable variables are introduced that reflect each construct. All variables are measured via seven-point Likert scales. Using a Google Form, 425 responses were collected that reflect the attitudes of the general public in Baghdad, Iraq. This dataset is useful for research on socio-economic problems; more specifically, it introduces reliable measurement models for street vending and the eight factors driving it. (shrink)

The primary objective of this research is to examine the potential influence of environmental, social, and governance (ESG) disclosure on cash holdings. Additionally, the study explores the role of earnings management (EM) practices as a mediating factor in this relationship. The sample comprises 797 companies listed on financial markets across 19 European countries, and the data spans from 2013 to 2019. The outcomes indicate a significant negative correlation between ESG disclosure and cash holdings, implying that ESG performance can be used (...) by management to resolve disputes with stakeholders. The outcomes further indicate that the existence of EM practices partially mediates the link between ESG disclosure and cash holdings. Moreover, they are robust by substitute cash holdings specification, three distinct initiatives of ESG disclosure (i.e., environment, social, and governance), and a two-stage least squares assessment. Therefore, the findings document that nonfinancial reporting in the form of ESG disclosure can assist in controlling agency conflict, leading to better valuations of company performance by stakeholders.

This paper investigates the effect of female representation on the board of directors on corporate response to stakeholders’ demands for increased public reporting about climate change-related risks. We rely on the Carbon Disclosure Project as a sustainability initiative supported by institutional investors. Greenhouse gas emissions measurement and its disclosure to investors can be thought of as a first step toward addressing climate change issues and reducing the firm’s carbon footprint. Based on a sample of publicly listed Canadian firms over the (...) period 2008–2014, we find that the likelihood of voluntary climate change disclosure increases with women percentage on boards. We also find evidence that supports critical mass theory with regard to board gender diversity. These findings reinforce initiatives being undertaken around the world to promote gender diversity in corporate governance while demonstrating board effectiveness in stakeholder management. (shrink)

It is hypothesized that iron from biological tissues, liberated during decay, may have played a role in inhibiting loss of anatomical information during fossilization of extinct organisms. Most tissues in the animal kingdom contain iron in different forms. A widely distributed iron‐bearing molecule is ferritin, a globular protein that contains iron crystallites in the form of ferrihydrite minerals. Iron concentrations in ferritin are high and ferrihydrites are extremely reactive. When ancient animals are decaying on the sea floor under anoxic environmental (...) conditions, ferrihydrites may initialize the selective replication of some tissues in pyrite FeS2. This model explains why some labile tissues are preserved, while other more resistant structures decay and are absent in many fossils. A major implication of this hypothesis is that structures described as brains in Cambrian arthropods are not fossilization artifacts, but are instead a source of information on anatomical evolution at the dawn of complex animal life.

According to the World Health Organization, female genital cutting affects millions of girls and women worldwide, particularly on the African continent and in the Middle East. This paper presents a plausible, albeit hypothetical, clinical vignette and then explores the legal landscape as well as the ethical landscape physicians should use to evaluate the adult patient who requests re-infibulation. The principles of non-maleficence, beneficence, justice, and autonomy are considered for guidance, and physician conscientious objection to this procedure is discussed as well. (...) Analyses of law and predominant principles of bioethics fail to yield a clear answer regarding performing female genital cutting or re-infibulation on an adult in the United States. Physicians should consider the patient’s physical, mental, and social health when thinking about female genital cutting and should understand the deep-rooted cultural significance of the practice.

The uses of statistical distributions for modeling real phenomena of nature have received considerable attention in the literature. The recent studies have pointed out the potential of statistical distributions in modeling data in applied sciences, particularly in financial sciences. Among them, the two-parameter Lomax distribution is one of the prominent models that can be used quite effectively for modeling data in management sciences, banking, finance, and actuarial sciences, among others. In the present article, we introduce a new three-parameter extension of (...) the Lomax distribution via using a class of claim distributions. The new model may be called the Lomax-Claim distribution. The parameters of the Lomax-Claim model are estimated using the maximum likelihood estimation method. The behaviors of the maximum likelihood estimators are examined by conducting a brief Monte Carlo study. The potentiality and applicability of the Lomax claim model are illustrated by analyzing a dataset taken from financial sciences representing the vehicle insurance loss data. For this dataset, the proposed model is compared with the Lomax, power Lomax, transmuted Lomax, and exponentiated Lomax distributions. To show the best fit of the competing distributions, we consider certain analytical tools such as the Anderson–Darling test statistic, Cramer–Von Mises test statistic, and Kolmogorov–Smirnov test statistic. Based on these analytical measures, we observed that the new model outperforms the competitive models. Furthermore, a bivariate extension of the proposed model called the Farlie–Gumble–Morgenstern bivariate Lomax-Claim distribution is also introduced, and different shapes for the density function are plotted. An application of the bivariate model to GDP and export of goods and services is provided. (shrink)

The past few years have witnessed a growing interest among scholars in the study of both the urban contour of the Andalusi cities and the estates called almunias. Almunia is a complex model of agricultural exploitation linked to elites and power, which also served other functions such as to provide space for solace. Ever since Joaquina Eguaras conducted the edition and translation of the Treatise of Agriculture of Ibn Luyūn in the seventies of the last century, her translation of the (...) last chapter about the organization of an almunia has been repeatedly reproduced and used to understand the archaeological remains of these properties or to interpret the information provided by the documentary sources. This article offers a new and more comprehensible translation of the text that attempts to correct some of the confusions Eguaras translation presents. For the purpose of comparability, the same manuscript, used earlier by Eguaras and currently preserved in the School of Arabic Studies, CSIC in Granada, has been used in the article. Additionally, the six marginal notes attached to the chapter, that have never been hitherto used in any study, have been included in this paper. The data provided by the 29 verses and six marginal notes, have been exhaustively analyzed and grounded in the existing knowledge about these estates along with the Andalusi agricultural practices of the time. Finally, this paper offers a hypothetical graphic reconstruction in which the ideas that Ibn Luyūn wanted to convey are visually translated. (shrink)

English summary: What is color? Are colors real properties of the world around us, or are they the secondary effects on our senses by the objects around us. Christophe Al-Saleh explores this contemporary philosophical debate over colors, objectivism, and subjectivism.

Psychological momentum (PM) is thought to be a force that influences judgment, emotion, and performance. Based on a review of the extant literature, we elucidate two distinct approaches that researchers have adopted in their study of PM: the input-centered approach and the output-centered approach. Consistent with the input-centered approach, we conceptualize PM as a process whereby temporal and contextual PM-like stimuli (i.e., perceptual velocity, perceptual mass, perceptual historicity, and perceptually interconnected timescales)—initially perceived as an impetus—are extrapolated to imagined future outcomes (...) through mental simulation. In turn, and consistent with the output-centered approach, we posit that mental simulation elicits experiential (e.g., perceptual, cognitive, emotional) and behavioral states that govern goal pursuit, and that the pursuit of goals further influences perceptions of self, environment, and action quality. In all, we suggest that PM is interdependently linked to perceptions and behaviors in the sense that PM both influences and is influenced by changes in self-perceptions, environmental perceptions, and behavior, and we conclude by linking the PM construct to recent work on prospection.

Over two decades ago a "quite revolution" overwhelmingly replaced knowledgebased approaches in natural language processing (NLP) by quantitative (e.g., statistical, corpus-based, machine learning) methods. Although it is our firm belief that purely quantitative approaches cannot be the only paradigm for NLP, dissatisfaction with purely engineering approaches to the construction of large knowledge bases for NLP are somewhat justified. In this paper we hope to demonstrate that both trends are partly misguided and that the time has come to enrich logical semantics (...) with an ontological structure that reflects our commonsense view of the world and the way we talk about in ordinary language. In this paper it will be demonstrated that assuming such an ontological structure a number of challenges in the semantics of natural language (e.g., metonymy, intensionality, copredication, nominal compounds, etc.) can be properly and uniformly addressed.

The purpose of this paper is twofold: (i) we argue that the structure of commonsense knowledge must be discovered, rather than invented; and (ii) we argue that natural language, which is the best known theory of our (shared) commonsense knowledge, should itself be used as a guide to discovering the structure of commonsense knowledge. In addition to suggesting a systematic method to the discovery of the structure of commonsense knowledge, the method we propose seems to also provide an explanation for (...) a number of phenomena in natural language, such as metaphor, intensionality, and the semantics of nominal compounds. Admittedly, our ultimate goal is quite ambitious, and it is no less than the systematic ‘discovery’ of a well-typed ontology of commonsense knowledge, and the subsequent formulation of the longawaited goal of a meaning algebra.

What is it for an agent to have a reason to do a certain action? Does this mean that she would desire to do the action under specified conditions, or that there is some external consideration, which she ought to follow? The former affective (i.e., desire-based) theory is ascribed to Humeans, whereas the latter cognitive theory is adopted by Kantians. The debate between the two views has seemingly ended up in a theoretical standoff, and most of the theorists of practical (...) reason have recently turned their attention to the motivational attitude—preceded either by affective attitudes or by cognitive attitudes—as a necessary constituent of having a reason. They contend that an agent has a reason to f only if, on certain occasions, she would be motivated to f: I refer to it as Motivation Reason Internalism. In this paper, I argue that Motivation Reason Internalism is a mirage; it does not obtain necessarily. I classify major versions of Motivation Reason Internalism into three idealized counterfactual versions, arguing that they obtain only contingently, since they all face counterexamples. The Motivation Reason Internalist might attempt to dodge the counterexamples by appealing to Contextual Motivations Reason Internalism, but I show that this move also fails. I discuss a third cause for motivation, some unconscious cause, other than cognitive or affective attitudes, which can still be a motivation maker or breaker. These unconscious causes, such as an underlying biological inclination or psychological bias, functions as motivation maker/breaker but not a reason maker/breaker. This makes room for a variety of cases in which we have reason to perform an action in the absence of any kind (i.e., actual or counterfactual) of motivation. (shrink)

We argue that logical semantics might have faltered due to its failure in distinguishing between two fundamentally very different types of concepts: ontological concepts, that should be types in a strongly-typed ontology, and logical concepts, that are predicates corresponding to properties of and relations between objects of various ontological types.

We will show that in such a framework a number of challenges in natural language semantics can be adequately and systematically treated. (shrink)

Despite overwhelming evidence suggesting that quantifier scope is a phenomenon that must be treated at the pragmatic level, most computational treatments of scope ambiguities have thus far been a collection of syntactically motivated preference rules. This might be in part due to the prevailing wisdom that a commonsense inferencing strategy would require the storage of and reasoning with a vast amount of background knowledge. In this paper we hope to demonstrate that the challenge in developing a commonsense inferencing strategy is (...) in the discovery of the relevant commonsense data and in a proper formulation of the inferencing strategy itself, and that a massive amount of background knowledge is not always required.

Avicenna believes that God must be understood in the first place as the Necessary Existent. In his various works, he provides different versions of an ingenious argument for the existence of the Necessary Existent—the so-called Proof of the Sincere —and argues that all the properties that are usually attributed to God can be extracted merely from God's having necessary existence. Considering the centrality of tawḥîd to Islam, the first thing Avicenna tries to extract from God's necessary existence is God's oneness. (...) The aim of the present Element is to provide a detailed discussion of Avicenna's arguments for the existence and unity of God. Through this project, the author hopes to clarify how, for Avicenna, the Islamic concept of monotheism is intertwined with the concept of essential existence. (shrink)
