Words are the essence of communication: They are the building blocks of any language. Learning the meaning of words is thus one of the most important aspects of language acquisition: Children must first learn words before they can combine them into complex utterances. Many theories have been developed to explain the impressive efficiency of young children in acquiring the vocabulary of their language, as well as the developmental patterns observed in the course of lexical acquisition. A major source of disagreement (...) among the different theories is whether children are equipped with special mechanisms and biases for word learning, or their general cognitive abilities are adequate for the task. We present a novel computational model of early word learning to shed light on the mechanisms that might be at work in this process. The model learns word meanings as probabilistic associations between words and semantic elements, using an incremental and probabilistic learning mechanism, and drawing only on general cognitive abilities. The results presented here demonstrate that much about word meanings can be learned from naturally occurring child-directed utterances (paired with meaning representations), without using any special biases or constraints, and without any explicit developmental changes in the underlying learning mechanism. Furthermore, our model provides explanations for the occasionally contradictory child experimental data, and offers predictions for the behavior of young word learners in novel situations. (shrink)

Recently, women entrepreneurship has become of particular interest to corporate social responsibility (CSR) scholarship, however, little is known about the impact of crises on women’s business activities and how they adapt to the disruptions and new market realities caused by a crisis. To design CSR initiatives that genuinely cater to the needs of women entrepreneurs, it is imperative to acquire an in-depth understanding of their unique experiences during times of crisis. This study employed a qualitative methodology to investigate the development (...) of resilience among women entrepreneurs amidst crisis. The study sample comprised Iranian women entrepreneurs who were operating health-related businesses during the COVID-19 pandemic. In addition to challenges related to money, market, management, motherhood, macro and meso level factors, women entrepreneurs were found to face crisis related challenges such as emotional exhaustion, altruism, fear of failure and uncertainty. Additionally, the findings revealed the different problem-based and emotion-based coping strategies (e.g., bootstrapping and emotional regulation) that women entrepreneurs used to build entrepreneurial resilience as well as business resilience. The resultant findings offer a comprehensive understanding of women entrepreneurs’ resilience-building process and suggest that resilience-building is a contextual as well as a gendered phenomenon. Implications for entrepreneurship research as well as women entrepreneurship and ethics literature is discussed. (shrink)

The human brain’s ongoing activity is characterized by intrinsic networks of coherent fluctuations, measured for example with correlated functional magnetic resonance imaging signals. So far, however, the brain processes underlying this ongoing blood oxygenation level dependent (BOLD) signal orchestration and their direct relevance for human behavior are not sufficiently understood. In this study, we address the question of whether and how ongoing BOLD activity within intrinsic occipital networks impacts on conscious visual perception. To this end, backwardly masked targets were presented (...) in participants’ left visual field only, leaving the ipsi-lateral occipital areas entirely free from direct effects of task throughout the experiment. Signal time courses of ipsi-lateral BOLD fluctuations in visual areas V1 and V2 were then used as proxies for the ongoing contra-lateral BOLD activity within the bilateral networks. Magnitude and phase of these fluctuations were compared in trials with and without conscious visual perception, operationalized by means of subjective confidence ratings. Our results show that ipsilateral BOLD magnitudes in V1 were significantly higher at times of peak response when the target was perceived consciously. A significant difference between conscious and non-conscious perception with regard to the pre-target phase of an intrinsic-frequency regime suggests that ongoing V1 fluctuations exert a decisive impact on the access to consciousness already before stimulation. Both effects were absent in V2. These results thus support the notion that ongoing slow BOLD activity within intrinsic networks covering V1 represents localized processes that modulate the degree of readiness for the emergence of visual consciousness.

How children go about learning the general regularities that govern language, as well as keeping track of the exceptions to them, remains one of the challenging open questions in the cognitive science of language. Computational modeling is an important methodology in research aimed at addressing this issue. We must determine appropriate learning mechanisms that can grasp generalizations from examples of specific usages, and that exhibit patterns of behavior over the course of learning similar to those in children. Early learning of (...) verb argument structure is an area of language acquisition that provides an interesting testbed for such approaches due to the complexity of verb usages. A range of linguistic factors interact in determining the felicitous use of a verb in various constructions—associations between syntactic forms and properties of meaning that form the basis for a number of linguistic and psycholinguistic theories of language. This article presents a computational model for the representation, acquisition, and use of verbs and constructions. The Bayesian framework is founded on a novel view of constructions as a probabilistic association between syntactic and semantic features. The computational experiments reported here demonstrate the feasibility of learning general constructions, and their exceptions, from individual usages of verbs. The behavior of the model over the timecourse of acquisition mimics, in relevant aspects, the stages of learning exhibited by children. Therefore, this proposal sheds light on the possible mechanisms at work in forming linguistic generalizations and maintaining knowledge of exceptions. (shrink)

This paper describes a live ethics case project that can be used to teach ethics in a broad variety of business classes. The live case differs from regular cases in that it involves a current situation. Students select an on-going or current event that involves ethical violations and write a case about it. They then present their case and run a debate about the challenges and issues outlined in the case and the actions that could have or should have been (...) taken. The dynamic project fulfills the key criteria for effective ethics education since it increases awareness of the complexity of ethical challenges, allows application of concepts, creates a personal emotional engagement in the case, is relevant, holds students accountable for their position, and creates a setting that encourages students to think critically about ethics.

In spite of orientation of philosophy in the western philosophy after renaissance when the relation between religion and philosophy was weakened and broken, in the Islamic world in particular Iranian society the strong relation appeared between religion and philosophy. However this relationship alleviated diversity and audaciousness of philosophical thought, but it deepened and widened religious thoughts. In fact, entrance of philosophical discussions in the realm of religion causes the rational interpretation of religion and lessens fanaticism and dogmatism and it excludes (...) superstition from religious thoughts. Philosophers like Averroes, Avicenna and Mulla Sadra have discussed the interaction of religion and philosophy. Islamic philosophy is completely an intellectual knowledgewhich differs from theology is based on revelatory texts. The title of Islamic philosophy displays the relationship between religion and philosophy. (shrink)

International reports welcoming Iran's recognition of transgender/sexuality and the permissibility of sex-change operations sometimes mixed celebration with an element of surprise: How could this be happening in an Islamic state? In other, and especially later, accounts, the sanctioning of sex-change became tightly framed through a comparison with punishment for sodomy and the presumed illegality of homosexuality. For legal and medical authorities in Iran, sex-change is explicitly framed as the cure for a diseased abnormality, and on occasion it is proposed as (...) a religio-legally sanctioned option for heteronormalizing people with same-sex desires and practices In this essayI aim to capture the polytheistic scattered practices that were a critical element in shaping trans-lives and subjectivities in this period in Iran, to map out a situated "cartography of desire," which locates the contemporary discourses and practices of transgender/sexuality in a longer historical trajectory and intersecting discursive sites, including medicine, religious doctrine, psychology, criminology, the family, trans-activism, and practices of everyday life. What transgender/sexual as a "human kind" means today in Iran is specific to a nexus formed not simply by transnational diffusion of concepts and practices from a Western heartland to the rest, but is also the product of the sociocultural and political situation in Iran over the previous half century.

Finally we give a characterization of hyper MV -algebras of order 3 or 4 based on the (...) hyper MV -ideals. (shrink)

The Flash Technique of Eye Movement Desensitization and Reprocessing is widely recognized for its effectiveness in reducing the effects of emotional responses associated with traumatic memories. Using a randomized-controlled trial methodology, this study attempts to establish the efficacy of the EMDR Flash Technique. This study’s sample includes volunteers who were involved in traffic accidents and were given the randomized EMDR Flash Technique and Improving Mental Health Training for Primary Care Residents Stress management module. The participants were given a socio-demographic data (...) form, the Depression-Anxiety-Stress 21 scale, the Impact of Event Scale-Revised, and the WHOQOL Quality of Life scale. Participants were evaluated using measurements taken before and after the application, as well as a one-month follow-up. The mean age of the participants was 36.20 years and 82.1% were female. The DASS-21 Anxiety, IES-R Intrusion, Avoidance, Total, and WHOQOL-BREF Psychological score improvements of the EMDR Flash Technique group were shown to be statistically significant when compared to the mhGAP group. However, no statistically significant difference in the DASS-21 Depression, Stress, Impact of Event Scale-Revised Hyperarousal WHOQOL-BREF General Health, Physical, Social Relationships, and Environment component scores was reported between the two groups. The present study’s findings clearly demonstrate that the EMDR Flash technique, when applied to persons involved in traffic accidents, is successful in improving anxiety, intrusion, avoidance, total traumatic stress, and mental quality of life symptoms for at least 1 month. We believe that these findings will improve the reliability and applicability of the EMDR Flash Technique, which was tested for the first time in a clinical randomized-controlled trial. (shrink)

BackgroundIn order to achieve the goals of the healthcare system, nursing managers are required to comply with ethical principles in decision-making. In complex and challenging healthcare settings, it is shown that the managers’ mere awareness of ethics does not suffice and managers need to be sensitive toward making ethical decisions.AimTo explore nursing managers and their sensitivity toward ethical decision-making by analyzing their related experiences.MethodThe current study has been conducted in Iran in 2017 through a qualitative content analysis approach. Nineteen nurse (...) managers were selected purposefully from different hospitals in Tehran. Data were collected using semi-structured, in-depth, face-to-face interviews, and after transcription, they were analyzed according to the Graneheim and Lundman method.Ethical considerationsThe research was approved by the ethics committee of Tarbiat Modares University, Tehran, Iran. Participants were informed about the purpose of the study and submitted written informed consents regarding their participation. The principle of autonomy, confidentiality, and anonymity was taken into account in data collection.ResultsFifteen subcategories, three categories (assertiveness, commitment, and insight), and one theme of excellent decision-making were the results of data analysis.DiscussionFindings showed that nursing managers’ sensitivity to ethical decision-making allows them to make the best decision by insight, commitment, and assertiveness. Making a morally excellent decision ensures that ethical principles are followed in the healthcare system.ConclusionConsidering that most managers are committed to making ethical decisions, it is required to develop the scope of their insights even further using a professional management and ethical principles training program. Also, by addressing some of the ethical barriers at personal and organizational levels, the assertiveness in managers can be improved, which in turn can facilitate their ethical decision-making.

Humans' voice offers the widest variety of motor phenomena of any human activity. However, its clinical evaluation in people with movement disorders such as Parkinson's disease lags behind current knowledge on advanced analytical automatic speech processing methodology. Here, we use deep learning-based speech processing to differentially analyze voice recordings in 14 people with PD before and after dopaminergic medication using personalized Convolutional Recurrent Neural Networks and Phone Attribute Codebooks. p-CRNN yields an accuracy of 82.35% in the binary classification of ON (...) and OFF motor states at a sensitivity/specificity of 0.86/0.78. The PAC-based approach's accuracy was slightly lower with 73.08% at a sensitivity/specificity of 0.69/0.77, but this method offers easier interpretation and understanding of the computational biomarkers. Both p-CRNN and PAC provide a differentiated view and novel insights into the distinctive components of the speech of persons with PD. Both methods detect voice qualities that are amenable to dopaminergic treatment, including active phonetic and prosodic features. Our findings may pave the way for quantitative measurements of speech in persons with PD. (shrink)

BackgroundNursing documentation as a pivotal part of nursing care has many implications for patient care in terms of safety and ethics.ObjectivesTo explore factors influencing nursing documentation from nurses’ perspectives in the Iranian nursing context.MethodsThis qualitative study was carried out using a qualitative content analysis of data collected from 2018 to 2019 in two urban areas of Iran. Semi-structured interviews (n = 15), observations, and reviews of patients’ medical files were used for data collection.Ethical considerationsThis study was conducted in accordance with (...) the ethical principles of research and regulations in terms of confidentiality of data, anonymity, and provision of informed consent.FindingsThe main theme of this study was “unsafe documentation.” Two categories, “types of errors in reporting” and “reasons of errors in reporting,” and 12 subcategories were developed indicating factors influencing nursing documentation in the Iranian nursing context.ConclusionIn general, individual, organizational, and national factors affected nursing documentation in Iran. In this respect, hiring more nurses, application of reforms in the healthcare management structure, devising appropriate regulations regarding division of labor, constant education of healthcare staff, establishment of clinical governance, improvement of interpersonal relationships, development of hardware and software techniques for documentation, and provision of support should be done to improve the quality of nursing documentation. The above-mentioned suggestions can help nurses with a safe, ethical, lawful, and reliable documentation in nursing practice. (shrink)

Source: Author: Mohammed Hussein Oroskhan, Esmaeil Zohdi From its beginning in the academic studies during the later nineteenth century, Romanticism has provoked ongoing debates over the nature of its definition. Nonetheless Morse Peckham has satisfactorily settled this matter by indicating that romanticism has dramatically altered the way of thinking therefore it should be distinctively met. For this purpose, he proposed that dealing with the concept of romanticism necessitate dividing it into two concepts of negative and positive romanticism in which a (...) transition is occurred from negative romanticism to positive romanticism however in some cases this transition may not become completed and is lead to the obscure origin of the sense of isolation among various romantic poets. To clearly illustrate Peckham's notion of negative romanticism, it is tried to explore Nima Yushij's Afsaneh who is known to be the most romantic poet of Persian literature. Based upon Peckham's notion of negative romanticism, Nima's sense of despair and isolation in Afsaneh is fully justified and it is highly suggested that Peckham's new perspective toward romanticism can eventually settle the conflicting views on the subject of Romanticism. ]]>.

This work introduces the Attack-Support Argumentation Framework (ASAF), an approach to abstract argumentation that allows for the representation and combination of attack and support relations. This framework extends the argumentation Framework with Recursive Attacks (AFRA) in two ways. Firstly, it adds a support relation enabling to express support for arguments; this support can also be given to attacks, and to the support relation itself. Secondly, it extends AFRA’s attack relation by allowing attacks to the aforementioned support relation. Moreover, (...) since the support relation of the ASAF has a necessity interpretation, the ASAF also extends the Argumentation Framework with Necessities (AFN). Thus, the ASAF provides a unified framework for representing attack and support for arguments, as well as attack and support for the attack and support relations at any level. (shrink)

Over the last decade, several extensions of Dung’s Abstract Argumentation Frameworks (AFs) have been introduced in the literature. Some of these extensions concern the nature of the attack relation, such as the consideration of recursive attacks, whereas others incorporate additional interactions, such as a support relation. Recently, the Attack–Support Argumentation Framework (ASAF) was proposed, which accounts for recursive attacks and supports, attacks to supports and supports to attacks, at any level, where the support relation is interpreted as necessity. Currently, to (...) determine the accepted elements of an ASAF (which may be arguments, attacks, and supports) it is required to translate such an ASAF into a Dung’s AF. In this work, we provide a formal characterization of acceptability semantics directly on the ASAF, without requiring such a translation. We prove that our characterization is sound since it satisfies different results from Dung’s argumentation theory; moreover, we formally show that the approach proposed here for addressing acceptability is equivalent to the preexisting one, in which the ASAF was translated into an AF. Also, we formalize the relationship between the ASAF and other frameworks on which it is inspired: the Argumentation Framework with Recursive Attacks (AFRA) and the Argumentation Framework with Necessities (AFN).

Seemingly distant practices of molecular biology and indigenous Xhosa healing have commonalities that I would like to bring into conversation in this article. The preclinical trial of an indigenous medicine brings them together in a research consortium. In this instance, both sets of experts are meant to collaborate in preparing a wild bush for it to pass the tests of the randomized clinical trial (RCT) and to potentially become a biopharmaceutical to counter the tuberculosis pandemic. I aim to tease out (...) how the two sets of actors and their respective practices converge and diverge in their healing hopes and ways of managing uncertainty. Ultimately, I am interested in understanding how the preferred process of making medicine “work” by each set of actors relies upon particular ways of knowing and not knowing life, bringing some ontologies into being, letting others wither away. The shared ways of knowing life as a movement of opening at the edges of the RCT are proposed as paths of recognition between one and the other practice. (shrink)

El presente trabajo intenta mostrar a la “Nueva Mainstream Más Pluralista” como un camino para abrir al diálogo entre la heterodoxia, que rechaza el insistente uso de modelos formales mainstream para acceder al mundo social complejo, y la ortodoxia que defiende el uso de tales modelos para conocer el mundo social. Como representante de los defensores de los modelos formales mainstream nos referiremos a la epistemología de Uskali Mäki y como crítico de tales modelos a la propuesta de Tony Lawson. (...) Explicitaremos las razones por las que estos autores sostienen sus posiciones, mostraremos qué es la “Nueva Mainstream Más Pluralista” y la propondremos como una manera de acercar a quienes adhieren a perspectivas tan diferentes respecto del uso de los modelos en las ciencias económicas.
