Emotion has a substantial influence on the cognitive processes in humans, including perception, attention, learning, memory, reasoning, and problem solving. Emotion has a particularly strong influence on attention, especially modulating the selectivity of attention as well as motivating action and behavior. This attentional and executive control is intimately linked to learning processes, as intrinsically limited attentional capacities are better focused on relevant information. Emotion also facilitates encoding and helps retrieval of information efficiently. However, the effects of emotion on learning and (...) memory are not always univalent, as studies have reported that emotion either enhances or impairs learning and long-term memory retention, depending on a range of factors. Recent neuroimaging findings have indicated that the amygdala and prefrontal cortex cooperate with the medial temporal lobe in an integrated manner that affords (i) the amygdala modulating memory consolidation; (ii) the prefrontal cortex mediating memory encoding and formation; and (iii) the hippocampus for successful learning and long-term memory retention. We also review the nested hierarchies of circular emotional control and cognitive regulation (bottom-up and top-down influences) within the brain to achieve optimal integration of emotional and cognitive processing. This review highlights a basic evolutionary approach to emotion to understand the effects of emotion on learning and memory and the functional roles played by various brain regions and their mutual interactions in relation to emotional processing. We also summarize the current state of knowledge on the impact of emotion on memory and map implications for educational settings. In addition to elucidating the memory-enhancing effects of emotion, neuroimaging findings extend our understanding of emotional influences on learning and memory processes; this knowledge may be useful for the design of effective educational curricula to provide a conducive learning environment for both traditional “live” learning in classrooms and “virtual” learning through online-based educational technologies.

The study has dealt with the theoretical context of the meaning of fame in language and term; also has shown that fame requires authenticity regardless of whether it is a word, narration or a classified work. On the other hand, it has examined that those, except for those who are examined with evidence, who are not famous among them will not be judged to be authentic or not. Later, it has pointed out the effect of fame on the correction of (...) the narrations and emphasized that fame is an important factor about the accuracy of the books in relation to their authors; and also sought an answer to the following question: Is fame the only factor in this or not? Thus, the problematic and some objectives of the study have been fulfilled, and the signs of the book’s finding of fame with the related author and the reasons that require this fame has been expressed. Among the indicators of the book’s fame from its author, arguments such as the narration from a group, the author’s clear statement that the book belongs to him, and the attribution of the book to him by his immediate surroundings in his own time have been mentioned. The study has examined six examples from the first three centuries, with the idea that the subject would be practical. In each century, two books were selected, and it was determined that one of them would be correct due to its reputation in relation to the author, and that the attribution of the other to the author will not be correct, since the other does not have a reputation. It has been determined that the attribution of his risālah about advices attributed to al-Imām Mālik and the book named al-Radd alâ'z-Zenādika wa'l-Cehmiyya, which is attributed to Imam Ahmed, are not valid.

Focusing on the supervisor–trainee relationship, this research set out to examine the impact of ethical leadership on two indicators of work-related well-being: work engagement and emotional exhaustion. Furthermore, this study sought to examine the mediating role of trust in supervisor in these relationships. Survey data were collected at two different points in time from 216 trainee accountants drawn from a variety of organisations. Structural equation modelling was used to test the research hypotheses. Results showed that, as hypothesised, trust in supervisor (...) fully mediated the effects of ethical leadership on work engagement and emotional exhaustion, respectively. The theoretical and practical implications of this research are discussed. (shrink)

Organised into three sections covering the place of semantics in linguistics, the description of sentence and word meanings, and current theoretical approaches to semantics, this book is aimed at undergraduates as well as general readers.

One of the main goals of assignments in the academic environment is to assess the students’ knowledge and mastery of a specific topic, and it is crucial to ensure that the work is original and has been solely made by the students to assess their competence acquisition. Therefore, Text-Matching Software Products are used by academic institutes to ensure academic integrity and address plagiarism. However, some students find ways to trick TMSPS. In this paper, files with the common tricks students do (...) to beat TMSPS have been created and investigates with nine academic level TMPS to evaluate their effectiveness against these tricks, identifying the strengths and weaknesses of each TMSP, and providing instructors with some practical tips on checking plagiarism effectively and spotting any tricks to cheat without getting noticed.

We investigate the impact of women shareholders on corporate social responsibility (CSR) and how they interact with women directors to exert a greater influence on CSR activities. Little is known about how women's ownership can enhance their roles in CSR practices. Based on data from Omani-listed firms during 2016–2020 and using CSR budgeting and spending as proxies for CSR activities, firms with women shareholders allocate more CSR budgeting and spend more money on CSR activities. However, we also find that women (...) directors can only affect CSR budgeting and spending if their representation on the board is increased. Furthermore, we find that firms with women shareholders and directors have higher CSR budgeting and spending. Further analysis reveals that women shareholders are more likely to spend money on CSR activities within the budgeted amount and are less likely to be associated with gaps between CSR budgeting and spending. This analysis also shows that the type of ownership (family versus non-family) influences women shareholders' effects on CSR budgeting and spending. Our empirical findings provide critical insights into how woman shareholders influence CSR actions. (shrink)

With the increasing interest in Islam and evolution, some Islamic thinkers have vehemently rejected evolution, while others have eagerly embraced it. However, those seeking to embrace evolution sometimes err in their interpretation of historical writings. Indeed, there are texts written by famous historical scholars of Islam who seem to suggest that humans have evolved from lower forms of species. These include Ibn Khaldūn, Jalāl ad‐Dīn Rūmī, al‐Jāhiz, and The Brethren of Purity (Ikhwān al Safā). Although this may be true, such (...) readings are a mistaken interpretation of the aforementioned authors who are actually referring to some form of the scalae naturae (the Great Chain of Being). This reference to the Great Chain of Being is unknown to some contemporary readers who mistakenly believe these writers to be discussing an evolutionary or a proto‐evolutionary theory. This article demonstrates how and why these historical records do not actually represent any notion of evolution as it is currently understood, in the hope of avoiding any further erroneous claims that seem to be proliferating among modern thinkers.

Most of the religions of the world are based on some fundamental moral principles of good conduct/virtues and prohibits its followers to do anything which is not good for the welfare of the society as a whole. This fundamental moral principal of good conduct, in Buddhism, is known as Pancha Shila. Pancha Shila is the basic assumption of moral activities for both households as well as for renunciates. It forms the actual practice of morality. Each time the precepts are upheld, (...) the moral volitions are strengthened, until morality becomes a habitualtrait through the condition of repetition. For the smooth functioning of a society, every Buddhist has to follow the five moral precepts i.e. abstaining from killing, abstaining from stealing, abstaining from sexual misconduct, abstaining from falsehood, abstaining from taking intoxicants. Jainism, Christianity, Hinduism and Islam too accept such ethical codes with little modification. These are called cardinal virtues. Jaina concept of Pancha Mahavrata is very close to Buddhist concept of Pancha Shila. In Jainism these are; Ahimsa, Satyam, Asteyam, Brahmacharyam, Aparigraha. Mahatma Gandhi too accepted these five cardinal virtues given by Jainism but he added two more in it which are; Fearlessness and Faith in God. The five precepts of Buddhism offers the moral conducts following which everyone can avoid evil deeds and can contribute in making this world a better world for present and future generations. The precept of abstaining from killing leads to the respect for other’s life. The precept of abstaining from stealing leads to the respect for other’s property. The precept of abstaining from sexual misconduct leads to the respect for one’s own dignity and dignity of other’s especially women. The precept of abstaining from falsehood leads to the respect for honesty. The precept of abstaining from taking alcohol leads to innumerable number of good qualities like respect for a clear mind, respect for modesty of other human beings, respect for money, respect for one’s own dignity, respect for other’s life and so on. The five precepts of Buddhism make a person disciplined, which is one of the most important ingredients for the development of overall personality of a person. A developing country cannot become a developed one unless its citizens are disciplined. If we analyze the five precepts given by Buddhism then, we find that the solution for most of world problems lies in it. If everyone follows five precepts then, I think this world will be transformed into a better place, a place where people have respects for other’s life and property, where everybody’s interest will be taken care of, where people will have an altruistic approach towards society. In short, this world can be transformed into a heaven. (shrink)

This study aims to investigate the impact of stakeholders’ views on the practices of green innovation, consequent effect on environmental and organizational performance, and moderating influence of innovation orientation. A quantitative method was employed for the sample size of 515 responses. To accumulate the data from the respondents, convenient random sampling was used. Data were collected from manufacturing and services firms through a field survey by using a closed-ended questionnaire based in the Punjab province of Pakistan. The analysis was done (...) using the structural equation model of the partial least square analysis method. Our findings proved a positive and significant link between stakeholders’ views on GI practices. A significant association has been found between GI practices and environmental and OP. The moderating effect was found to be negative but statistically significant. This research offers numerous contributions and provides decision-making insinuations. (shrink)

In this work, Kenan Malik explores the history of moral thought as it has developed over three millennia, from Homer's Greece to Mao's China, from ancient India to modern America. It tells the stories of the great philosophers, and breathes life into their ideas, while also challenging many of our most cherished moral beliefs.

Contemporary bioethics has evolved over the past 40 years predominantly as a “Western” construct drawing fundamental inspiration for its conceptual and methodological frameworks from secular, Anglo-American philosophical traditions. American bioethicists can be credited with playing a defining role in the globalization of this new discipline to the developing countries of the world, but in this process, in the words of LaFleur, “Bioethics has become international without becoming internationalized.” Among the criticisms leveled against the dominant American model of bioethics is that (...) in its focus on universalism it ignores local cultural and religious influences that are vital to the comprehension of the moral life in many societies. Medical sociologist Renée C. Fox and historian Judith P. Swazey have termed this as a form of “cultural myopia.”. (shrink)

Current development in a deep neural network has given an opportunity to a novel framework for the reconstruction of a holographic image and a phase recovery method with real-time performance. There are many deep learning-based techniques that have been proposed for the holographic image reconstruction, but these deep learning-based methods can still lack in performance, time complexity, accuracy, and real-time performance. Due to iterative calculation, the generation of a CGH requires a long computation time. A novel deep generative adversarial network (...) holography framework is proposed for hologram reconstruction. This novel framework consists of two phases. In phase one, we used the Fresnel-based method to make the dataset. In the second phase, we trained the raw input image and holographic label image data from phase one acquired images. Our method has the capability of the noniterative process of computer-generated holograms. The experimental results have demonstrated that the proposed method outperforms the existing methods.

This study aims to critique the concept of active learning in childhood education based on Hegelian Bildung. We have defined childhood education from the perspective of Hegel’s Bildung in The Phenomenology of Spirit. We describe childhood education as a ‘primary Bildung’ having the aim of ‘entering into the conceptual world’. This aim indicates that children can and are required to express their experiences in conceptual language. Finally, we critique the conceptual components of active learning from the Hegelian point of view (...) and suggest three alternative components: ‘child-educator interaction’, ‘understanding historical knowledge’, and ‘addressing concrete-abstract affairs.’ We suggest that the concept of active learning needs to be replaced by ‘Communicative-Interactive Learning (CIL)’. CIL takes both objectivity and subjectivity into account during the process of knowledge formation in education. (shrink)

Neonatal brain monitoring in the neonatal intensive care units (NICU) requires a continuous review of the spontaneous cortical activity, i.e., the electroencephalograph (EEG) background activity. This needs development of bedside methods for an automated assessment of the EEG background activity. In this paper, we present development of the key components of a neonatal EEG background classifier, starting from the visual background scoring to classifier design, and finally to possible bedside visualization of the classifier results. A dataset with 13,200 5-minute EEG (...) epochs (8–16 channels) from 27 infants with birth asphyxia was used for classifier training after scoring by two independent experts. We tested three classifier designs based on 98 computational features, and their performance was assessed with respect to scoring system, pre- and post-processing of labels and outputs, choice of channels, and visualization in monitor displays. The optimal solution achieved an overall classification accuracy of 97% with a range across subjects of 81–100%. We identified a set of 23 features that make the classifier highly robust to the choice of channels and missing data due to artefact rejection. Our results showed that an automated bedside classifier of EEG background is achievable, and we publish the full classifier algorithm to allow further clinical replication and validation studies.

This book on Philosophy for Children is a compilation of articles written by its founders and the movement's leaders worldwide. These articles have been prepared in the dialogue and interview format. Part I explains the genesis of the movement, its philosophical and theoretical foundations. Part II examines the specialized uses of philosophical dialogues in teaching philosophy, morality, ethics and sciences. Part III examines the theoretical concerns such as the aims of the method in regards to the search for truth or (...) sense of meaning, or the debate on the novel or short stories and its characteristics. Part IV explains the practices of P4C worldwide and the issue of cultural differences, the ways of the community of inquiry and the necessary adaptation to suit local concerns. The book concludes with a notable review of the progress of P4C, the obstacles, and its international spread to over 60 countries. These penetrating insights make the book an incredibly rich resource for anyone interested in or involved with implementing a P4C programme. Brave Old Subject, Brave New World Teaching Science and Morality Via P4C Showing Children can do Philosophy. (shrink)

A cornerstone of modern mathematical logic is the diagonal lemma of Gödel and Carnap. It is used in e.g. the classical proofs of the theorems of Gödel, Rosser and Tarski. From its first explication in 1934, just essentially one proof has appeared for the diagonal lemma in the literature; a proof that is so tricky and hard to relate that many authors have tried to avoid the lemma altogether. As a result, some so called diagonal-free proofs have been given for (...) the above mentioned fundamental theorems of logic. In this paper, we provide new proofs for the semantic formulation of the diagonal lemma, and for a weak version of the syntactic formulation of it. (shrink)

At the beginning of every year, we expect to see worthwhile improvements on the past. The end of 2016 showcased many important issues in the scientific world, ranging from criticisms of research misconduct and fraud to the introduction of new scientometrics.

In the internet era spam has become a big problem. Researchers are troubled with unsolicited or bulk spam emails inviting them to publish. However, this strategy has helped predatory journals hunt their prey and earn money. These journals have grown tremendously during the past few years despite serious efforts by researchers and scholarly organizations to hinder their growth. Predatory journals and publishers are often based in developing countries, and they potentially target researchers from these counties by using different tactics identified (...) in previous research. In response to the spread of predatory publishing, scientists are trying to develop criteria and guidelines to help avoid them—for example, the recently reported “predatory rate”. This article attempts to highlight the strategies used by predatory journals to convince researchers to publish with them, report their article processing charges, note their presence in Jeffrey Beall’s List of Predatory Publishers, rank them based on the predatory rate, and put forward suggestions for junior researchers, who are the most likely targets of predatory journals.

Managing non-communicable diseases in crisis-affected and fragile humanitarian contexts requires special attention because primary health care systems often collapse or become compromised in such settings. As a result, addressing and managing these diseases become more challenging. Humanitarian organizations that intervene in crisis situations are increasingly including NCD management in the services they support and provide; however, they encounter a range of issues such as ensuring the quality of care, sustainability of programs, and the possibility of unintended harms. This case study (...) explores ethical considerations raised by a mobile NCD program run by an international humanitarian organization in a country affected by a protracted civil war. (shrink)

He raises issues related to P4C/CPI as representative of a larger educational paradigm, which he calls “reflective education,” and weighs its prospects for replacing what he calls the “traditional paradigm” worldwide. He also queries the two scholars on issues such as criteria for appropriate texts/stimuli for practicing philosophy with children; issues (...) around teacher preparation; the epistemological paradigm of CPI and its relation to the logic of scientific discovery and mathematical proof; the status of CPI as a “new” or reconstructed form of the discipline of philosophy; the prospects for a narrative approach to philosophy as exemplified in the new literary genre of the Lipmanian philosophical novel for children; the relationship between the practice of CPI in schools and the possibility for educational reconstruction, particularly in the area of social democracy and school governance; the significance of understanding the child as a “privileged stranger” to patriarchal colonialist culture, and the social implications of a form of education based on dialogue rather than forced enculturation; and the implications for the construction and delivery of curriculum in a school in which CPI and emergent curriculum were central organizational elements.

To explore the knowledge, attitudes and practices regarding plagiarism in a large culturally diverse sample of researchers who participated in the AuthorAID MOOC on Research Writing. An online survey was designed and delivered through Google Forms to the participants in the AuthorAID MOOC on Research Writing during April to June 2017. A total of 765 participants completed the survey, and 746 responses were included in the analysis. Almost all participants reported knowledge of the term “plagiarism”, and 89.1% of them understand (...) the meaning of the term before joining the course. Most participants reported that their university does not provide access to plagiarism detection software, and 35% participants admitted they had been involved in plagiarism during their education. Overall attitudes toward plagiarism indicated low acceptance of plagiarism. Moreover, low scores were reported for approval attitude, disapproval attitude, and knowledge of subjective norms. The most common reason for plagiarizing was lack of time, and the most common consequence was the perception that “those who plagiarize are not respected or seen positively”. Developing country researchers appear to be familiar with the concept of plagiarism, but knowledge among the participants surveyed here was incomplete. Knowledge about plagiarism and awareness of its harmfulness must be improved, because there is an obvious relationship between attitudes toward plagiarism and knowledge, reasons and consequences. The use of plagiarism-detection software can raise awareness about plagiarism. (shrink)

This study linked background TV and socioeconomic status to minority children’s Persian vocabulary development. To this end, 80 Iranian preschool children from two minority groups of Arabs and Turks were selected using stratified random sampling. They were simultaneous bilinguals, i.e., their mother tongue was either Arabic or Azari and their first language was Persian. Language sample analysis was used to measure vocabulary development through a 15-min interview by language experts. The LSA measures included total number of utterances, total number of (...) words, total number of new words, and mean length of utterance. A series of independent-samples t test, paired-samples t test, and repeated measures MANOVA tests were ran to examine data. Results showed significant improvements in children’s vocabulary scores from pretest to posttest for all children. In addition, high-SES children scored higher on the vocabulary measures in pretest and posttest. Moreover, background TV was associated with higher means in the TNW and the NDW in groups. The researchers concluded that background TV may be related to higher vocabulary scores in low-SES families as it may compensate for some linguistics gaps in these families including lower amount of child-parent interaction, play, and parents’ level of literacy.

The removal of Beall’s blog may result in increased numbers of predatory journals and their subsequent victims. Recognizing this, the World Association of Medical Editors suggested criteria for identifying predatory journals in a statement issued on February 18, 2017.

However, a few lapses and limitations need to be taken into account when translating these policies to the situation in developing countries. This letter presents several cases of legitimate journals (...) and platforms from the developing world that may be erroneously categorized as predatory according to the WAME criteria. We also suggest some improvements in these journals’ policies. (shrink)

Background:Experiencing moral distress is traumatic for nurses. Ignoring moral distress can lead to job dissatisfaction, improper handling in the care of patients, or even leaving the job. Thus, it is crucial to use valid and reliable instruments to measure moral distress.Objective:The purpose of this study was to determine the reliability and the validity of the Persian version of the Moral Distress Scale–Revised among a sample of Iranian nurses.Research design:In this methodological study, 310 nurses were recruited from all hospitals affiliated with (...) the Qazvin University of Medical Sciences from February 2014 to April 2015. Data were collected using a demographic questionnaire and the Moral Distress Scale–Revised. The construct validity of the Moral Distress Scale–Revised was evaluated using principal component analysis and confirmatory factor analysis. Internal consistency reliability was assessed with Cronbach’s alpha.Ethical considerations:This study was approved by the Regional Committee of Medical Research Ethics. The ethical principles of voluntary participation, anonymity, and confidentiality were considered.Findings:The construct validity of the scale showed four factors with eigenvalues greater than one. The model had a good fit ( χ2(162) = 307.561, χ2/ df = 1.899, goodness-of-fit index =.904, comparative fit index =.927, incremental fit index =.929, and root mean square error of approximation (90% confidence interval) =.049 (.040–.057)) with all factor loadings greater than.5 and statistically significant. Cronbach’s alpha coefficients were.853,.686,.685, and.711for the four factors. Moreover, the model structure was invariant across different income groups.Discussion and conclusion:The Persian version of the Moral Distress Scale–Revised demonstrated suitable validity and reliability among nurses. The factor analysis also revealed that the Moral Distress Scale–Revised has a multidimensional structure. Regarding the proper psychometric characteristics, the validated scale can be used to further research about moral distress in this population. (shrink)

Pessimistic meta-induction is a powerful argument against scientific realism, so one of the major roles for advocates of scientific realism will be trying their best to give a sustained response to this argument. On the other hand, it is also alleged that structural realism is the most plausible form of scientific realism; therefore, the plausibility of scientific realism is threatened unless one is given the explicit form of a structural continuity and minimal structural preservation for all our current theories. This (...) essay aims to present what we call expansive structures, which are the structures that can be reconstructed from geometrized Newtonian gravitation and are capable of expanding into general relativity, explicitly. In this way, pessimistic meta-induction will be undermined. (shrink)

We argue that, under the usual assumptions for sufficiently strong arithmetical theories that are subject to Gödel’s First Incompleteness Theorem, one cannot, without impropriety, talk about *the* Gödel sentence of the theory. The reason is that, without violating the requirements of Gödel’s theorem, there could be a true sentence and a false one each of which is provably equivalent to its own unprovability in the theory if the theory is unsound.

Health research for progress in the control and conquest of disease afflicting man is unquestionable. Concerns arise when motives other than the advancement of scientific knowledge and benefit for individuals and society are the driving force behind clinical trials. These conflicts of interests become even more pronounced when dealing with populations rendered vulnerable by virtue of poverty and ignorance. South Asia with its teeming millions represents one such region. This essay examines the reasons that make this population vulnerable to exploitation. (...) Informed consent in the process of research is an area where such conflicts are prone to arise. In order to ensure that conflicting interests of researchers and funding agencies are kept in check, the processes of informed consent and ethical review of research need to be strengthened. Suggestions are put forward to modify the consent process to match the needs of South Asia and to strengthen the ethical review process for safeguarding the rights of the study subjects. But perhaps the most important safeguard against exploitation is the virtuous researcher himself with noble intentions. (shrink)

Social media particularly Facebook has become a popular platform amongst medical professionals for both social and professional interactions. However, given the nature of such platforms, their use raises ethical concerns including violation of patient privacy and blurring of classical professional and patient-physician relationship boundaries.

Results show that 44% of respondents found professional utility for Facebook. 36% of respondents had never changed their privacy settings and 44% indicated lack of confidence in current privacy settings of the medium. Respondents had posted identifiable patient content and non-identifiable patient content, with students and trainees posting such content more frequently than faculty. (shrink)

It is shown that all the provably total functions of Basic Arithmetic BA, a theory introduced by Ruitenburg based on Predicate Basic Calculus, are primitive recursive. Along the proof a new kind of primitive recursive realizability to which BA is sound, is introduced. This realizability is similar to Kleene's recursive realizability, except that recursive functions are restricted to primitive recursives.

Interesting as they are by themselves in philosophy and mathematics, paradoxes can be made even more fascinating when turned into proofs and theorems. For example, Russell’s paradox, which overthrew Frege’s logical edifice, is now a classical theorem in set theory, to the effect that no set contains all sets. Paradoxes can be used in proofs of some other theorems—thus Liar’s paradox has been used in the classical proof of Tarski’s theorem on the undefinability of truth in sufficiently rich languages. This (...) paradox (as well as Richard’s paradox) appears implicitly in Gödel’s proof of his celebrated first incompleteness theorem. In this paper, we study Yablo’s paradox from the viewpoint of first- and second-order logics. We prove that a formalization of Yablo’s paradox (which is second order in nature) is non-first-orderizable in the sense of George Boolos (1984). (shrink)

To investigate the effect of philosophical thinking on the development of reasoning skills and behavioral performance among Iranian primary school students, we conducted a qualitative method study with ten fourth grade students (including boys and girls)selected from different primary schools in Tehran1.

Data collection strategies of this study including the authors’ observations during sessions, children’s parents’ observations and reports, and interviews with children and their parents. Our research result shows that reasoning skills enhance communication skills by enabling children to express their ideas more persuasively. We also found that children act more confidently and independently. (shrink)
