The expanding demands of healthcare necessitate novel methods of increasing the supply of trained professionals to enhance the delivery of care services. One means of doing so is to expand allied health professionals’ scope of practice. This paper explores the ethics of two examples of such expansion in ophthalmology, comparing the widely accepted practice of nurses administering intravitreal injections and the relatively less prevalent optometrists functioning as physician extenders. We conducted a literature review of empirical research into both practices and (...) conclude that nurses administering intravitreal injections are ethically justified. With adequate standardized training, optometrists can also function as primary eye care providers to improve accessibility to eye care. We provide an algorithm for the ethical introduction of innovative expanded allied healthcare. (shrink)

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.

What are the neural correlates of conscious visual awareness? Tackling this question requires contrasting neural correlates of stimulus processing culminating in visual awareness with neural correlates of stimulus processing unaccompanied by awareness. To contrast these two neural states, one must be able to erase an otherwise visible stimulus from awareness. This paper describes and critiques visual phenomena involving dissociation of physical stimulation and conscious awareness: degraded stimulation, visual masking, visual crowding, bistable figures, binocular rivalry, motion-induced blindness, inattentional blindness, change blindness (...) and attentional blink. While no single strategy stands above the others, those producing changing visual awareness despite invariant physical stimulation are clearly preferable. (shrink)

Engaging communities in community-based health research is increasingly being adopted in low- and middle-income countries. The use of community advisory boards is one method of practicing community involvement in health research. To date, few studies provide in-depth accounts of the strategies that CAB members use to practice community engagement. We assessed the perspectives, experiences and practices of the first local CAB in Eswatini, which was implemented as part of the MaxART Early Access to ART for All study. Trained Swazi research (...) assistants conducted two focus group discussions and 13 semi-structured interviews with CAB members who had been part of the MaxART study for at least 2.5 years. Interviews explored CAB composition and recruitment, the activities of CAB members, the mechanisms used to engage with communities and the challenges they faced in their role. The MaxART CAB played an active role in the implementation of the Early Access to Art for All study, and activities mainly focused on: promoting ethical conduct, in particular privacy, consent and confidentiality; communication and education, communicating about the study and educating the community on the benefits of HIV testing and early access to HIV treatment; and liaising between the community and the research team. Strategies for interacting with communities were varied and included attending general community meetings, visiting health facilities and visiting public places such as cattle dipping tanks, buses, bars and churches. Differences in the approach to community engagement between CAB members living in the study areas and those residing outside were identified. The experiences of the first CAB in Eswatini demonstrate that community engagement using CABs is a valuable mechanism for engaging communities in implementation studies. Considerations that could impact CAB functioning include clearly defining the scope of the CAB, addressing issues of CAB independence, the CAB budget, providing emotional support for CAB members, and providing continuous training and capacity building. These issues should be addressed during the early stages of CAB formation in order to optimize functioning. (shrink)

Recent years have seen an increased turning to the “wisdom of the East” when addressing issues on the environment. The risk of misappropriating its tenets in order to make them conform to the Western system is extremely high however. This paper will lay bare the early texts of Daoism so as to disprove claims that Nature is mystical, antithetical to technology, and subservient to human consciousness. It shall argue that Nature not only arises from a non-anthropocentric source in Dao but (...) that this arising takes place across three levels of reality: Dao’s mystery, the cosmogony of the One-and-Many, and the fourfold comprised of Dao, Heaven, Earth, and man. The result is a vision of Nature no longer bound to a singular actuality but one whose presence is felt across an endless range of possibilities as the substantive realization of Dao. (shrink)

The sharing economy has been examined from many angles, including the engagement of customers, the capabilities of the technological platforms, and the experiences of those who sell products or services. We focus on labor in the sharing economy. Labor has been regarded as one type of asset exchanged in the sharing economy, as part of the customer interface when services are sold, or as a party vulnerable to exploitation. We focus on labor as a position in relationship to owners of (...) capital. While new typologies to characterize the sharing economy are emerging, we argue that a well-established framework that has been applied across historic types of work arrangements can offer a robust analysis of enduring and new labor issues. We draw upon labor process theory from early formulations to recent applications to guide an analysis appropriate to the sharing economy. We use both central and less explored concepts from LPT and use Uber as a case to illustrate application of the framework. By considering labor, capital, and the power dynamics between them, we draw attention to unequal exchange and distributive justice, fundamental for taking a business ethics approach to labor in the sharing economy.

This article describes challenges of conducting an HIV prevention program involving 40 male and female participants ages 12–18 in Hammanskraal, South Africa, aimed at increasing awareness and knowledge of laws protecting children’s sexual health rights and access to services through a culturally based “study circle” format. Challenges highlighted by the project included Institutional Review Board approval of youth consent procedures, cooperation and coordination with local policymakers, the need to modify presentation materials to youths’ comprehension levels, availability of youth-based sexual health (...) service providers, and cultural ambiguity over parental involvement in youth health care decisions and laws pertaining to sexual relationships among minors.

Serlio achieved fame as an architect and the author of seven books on architecture, but his activities as a painter are hardly known. The recently discovered autograph manuscript reveals his thinking about this 'most noble art': collectively its pages form the introduction to an unfinished treatise on painting. As with his architectural discourse, Serlio's approach to writing about painting is entirely practical. In no sense a humanist reflection on the subject of art, the work was planned as an illustrated manual (...) and pedagogical tool for the novice painter. The discussion opens with a first section on disegno where the rudiments of drawing are outlined. Very quickly Serlio turns to foreshortening and perspectives on the human figure, emphasising the infinite nuances possible as the body to be represented moves. Such concerns disclose the influence of his mentor Baldassare Peruzzi and association with other members of Raphael's studio. As presented in this manuscript, the manual may have graphically resembled Dürer's Vier Bücher in its printed form, but the rules of disegno respect the Italian workshop tradition as we know it from Carlo Urbino's Le regole del disegno and the Leonardesque heritage. Serlio's projected volume of painting instruction may be regarded as a first literary experiment—a precursor to his later illustrated books on architecture. (shrink)

Multivariate pattern analysis can reveal new information from neuroimaging data to illuminate human cognition and its disturbances. Here, we develop a methodological approach, based on multivariate statistical/machine learning and time series analysis, to discern cognitive processing stages from functional magnetic resonance imaging (fMRI) blood oxygenation level dependent (BOLD) time series. We apply this method to data recorded from a group of healthy adults whilst performing a virtual reality version of the delayed win-shift radial arm maze (RAM) task. This task has (...) been frequently used to study working memory and decision making in rodents. Using linear classifiers and multivariate test statistics in conjunction with time series bootstraps, we show that different cognitive stages of the task, as defined by the experimenter, namely, the encoding/retrieval, choice, reward and delay stages, can be statistically discriminated from the BOLD time series in brain areas relevant for decision making and working memory. Discrimination of these task stages was significantly reduced during poor behavioral performance in dorsolateral prefrontal cortex (DLPFC), but not in the primary visual cortex (V1). Experimenter-defined dissection of time series into class labels based on task structure was confirmed by an unsupervised, bottom-up approach based on Hidden Markov Models. Furthermore, we show that different groupings of recorded time points into cognitive event classes can be used to test hypotheses about the specific cognitive role of a given brain region during task execution. We found that whilst the DLPFC strongly differentiated between task stages associated with different memory loads, but not between different visual-spatial aspects, the reverse was true for V1. Our methodology illustrates how different aspects of cognitive information processing during one and the same task can be separated and attributed to specific brain regions based on information contained in multivariate patterns of voxel activity.

Colour synaesthesia is the mental experience involving a strong association between specific colours and specific auditory stimuli, such as words, or achromatic visual stimuli, such as numerals or letters. In the contemporary literature on colour synaesthesia, the majority view treats the phenomenon as one arising from some of the same neural events mediating colour perception triggered by genuinely coloured objects; this view that synaesthesia is perceptually based, however, is not universally endorsed. What strategies have been utilized to evaluate the perceptual (...) reality of colour synaesthesia, and what is the evidence produced by those strategies? This chapter tackles those questions within the context of colour graphemic synaesthesia, the most widely studied form of synaesthesia. We divide the research strategies into those employing behavioral measures to assess whether synaesthetia influences performance on tasks known to be sensitive stimulus colour and those employing indirect measures that use physiological responses as proxies for colour perception. Our chapter concludes that there is sufficient justification for the belief in the perceptual reality of colour grapheme synaesthesia. At the same time, we applaud those who remain disbelievers, for their skepticism has underscored the logical issues surrounding research on this question. (shrink)

"In 'Justice', the result of many years' thoughtful exploration of that subject, Professor Perelman explains the conceptual origins of justice (both social and historical) and discusses the relationships between justice and justification, between justice and reason, and between reason and values. He considers the matter of a core of meaning, common to all, concerning the concept of justice, and raises essential questions such as why do people disagree about the problems of justice and whether a difference exists between a political (...) conception and a philosophical conception of justice."--Cover.

Explores the cosmological and metaphysical thought in the Zhuangzi from the perspective of nothingness. Zhuangzi and the Becoming of Nothingness offers a radical rereading of the Daoist classic Zhuangzi by bringing to light the role of nothingness in grounding the cosmological and metaphysical aspects of its thought. Through a careful analysis of the text and its appended commentaries, David Chai reveals not only how nothingness physically enriches the myriad things of the world, but also why the Zhuangzi prefers nothingness (...) over being as a means to expound the authentic way of Dao. Chai weaves together Dao, nothingness, and being in order to reassess the nature and significance of Daoist philosophy, both within its own historical milieu and for modern readers interested in applying the principles of Daoism to their own lived experiences. Chai concludes that nothingness is neither a nihilistic force nor an existential threat; instead, it is a vital component of Dao’s creative power and the life-praxis of the sage. “Chai provides an elaborate philosophical meontological interpretation of the ontology/cosmology found in the Zhuangzi and the implications for existential practice. It’s a close, careful, but in many respects quite original reading of the classic that contributes significantly to the field of philosophical Daoist studies.” — Geir Sigurðsson, author of Confucian Propriety and Ritual Learning: A Philosophical Interpretation.

In this ground-breaking work, Deborah Cowen makes the first book-length critical intervention into the field of business logistics. Tracing the social, spatial and political transformations wrought by the ‘logistics revolution’, Cowen argues that logistical systems have blurred the boundaries between production and circulation, civilian and military life, and geopolitics and geo-economics, constructing an architecture of the supply chain animated by both the art of war and the science of business. This review considers the political stakes of Cowen’s argument that logistics (...) has reconfigured capitalist social relations of production, especially in relation to the securitisation of spatial mobility and the restructuring of the labour process. In particular, Cowen’s wager that logistical supply-chains are characterised by their vulnerability – and that attendant possibilities for building solidarity emerge out of movements that disrupt such flows – is interrogated in order to question whether such interruptions effectively produce challenges to value-in-motion, or actually become integral to processes of value production.

This paper relocates the philosophical discourse on the Thing (das Ding) to the world of classical Daoism. In doing so, it explores the bond between the One, the Thing and its signifier before discussing how the Thing unveils itself to the world while receiving the gift of nothingness from Dao. It furthermore contends that the two most prominent discussions of the Thing in the Western tradition--those by Heidegger and Lacan--while philosophically valuable in their own right, fail to provide the degree (...) of profundity seen via a Daoist reading. What will become apparent is that the Thing qua the One serves to delineate the cosmological and human realms of reality, negating any inclination one might have of it as being anything but mystical.

Modem neo-Confucianism is studied at two levels, one is at the historical level and the other at the academic level. Modern neo-Confucianism at the historical level was developed in the modern context, but its basic content belongs to the traditional Confucianism or the study of Confucian classics. Modem neo-Confucianism at the academic level recognizes both the deficiencies of the traditional Confucianism and rationality of western learning, and dedicates itself to the modernization of Confucianism. Though Ma Yifu's moral philosophy is developed (...) in the context of modem Chinese culture, it fails to deal with the problem of modern transformation of Confucian ethical values and its content still belongs to the traditional Confucianism. So it should be labeled as the modern neo-Confucianism in the historical sense. In this paper, the author makes a systematic exploration and an evaluation of Ma Yifu's ethical thought. (shrink)

This collection is intercultural philosophy at its best. It contextualizes the global significance of the leading figures of Western phenomenology, including Husserl, Hegel, Nietzsche, Heidegger, Buber and Levinas, enters them into intercultural dialogue with the Daoism of Laozi and Zhuangzi and in doing so, breaks new ground. By presenting the first sustained analysis of the Daoist worldview by way of phenomenological experience, this book not only furthers our understanding of Daoism and phenomenology, but delves deeper into the roots of human (...) thinking, aesthetic expression, and its impact on the modern social world. The international team of philosophers approach the phenomenological tradition in the broadest sense possible, looking beyond the phenomenological language of Husserl. With chapters on art, ethics, death and the metaphor of dream and hermeneutics, this collection encourages scholars and students in both Asian and Western traditions to rethink their philosophical bearings and engage in meaningful intercultural dialogue.

Eric Nelson's Chinese and Buddhist Philosophy in Early Twentieth-Century German Thought opens with the following: "The work before you is an interpretive journey through the historical reception of Chinese and Buddhist philosophy in modern German thought, focusing in particular--albeit not exclusively--on the early twentieth century. Its intent is to describe and analyze the intertextual nexus of intersecting sources for the sake of elucidating implications and critical models for intercultural hermeneutics and intercultural philosophy. The possibility of such a philosophy is confronted (...) by the persistent myth and prejudice that philosophy is and can only be a unique and exclusive Western spiritual achievement" (p.... (shrink)

Intelligent communication processing in English aims to obtain effective information from unstructured text data using various text processing techniques. Text vector representation and text similarity calculation are important fundamental tasks in the whole field of natural language processing. In response to the shortcomings of existing sentence vector representation models and the singularity of text similarity algorithms, improved models and algorithms are proposed based on a thorough study of related domain technologies. This paper presents an in-depth and comprehensive study of text (...) vectorization representation and text similarity calculation algorithms in the field of natural language processing. The existing text vectorized representation models and text similarity computation algorithms are described, and their shortcomings are summarized to provide a basis for the background and significance of this paper, as well as to provide ideas for improvement directions. It is experimentally verified that the sentence vector model proposed in this paper achieves higher accuracy than the SIF sentence vector model for text classification tasks. In the task of text similarity computation, it achieves better results in three evaluation metrics: accuracy, recall, and F1 value. The algorithm also improves the computational efficiency of the model to a certain extent by removing feature words with low feature contribution. The algorithm first improves the deficiencies of the traditional word-shift distance algorithm by defining multifeature fusion weights and realizes a text similarity calculation algorithm based on multifeature weighted fusion with better similarity calculation results. Then, a linear weighting model is constructed to further combine the similarity calculation results of the hierarchical pooled IIG-SIF sentence vectors to realize the multimodel fusion text similarity calculation algorithm.

This study takes a systemic functional multimodal social semiotic approach to the analysis and discussion of image and text relations in two sets of data. First, patterns of contextualisation of images and text in the online magazines Dabiq and Rumiyah produced by the Islamic extremist organisation which refers to itself as Islamic State are examined. The second data set consists of a sample of texts from Western online news and blog sites which include recontextualisations of images found in the first (...) data set. A sample of examples of the use and re-use of images is discussed in order to identify patterns of similarity and difference when images and text are recontextualised. It is argued that the ISIS material tends to foreground the interpersonal metafunction in combination with the textual metafunction, while the other data set tends to foreground the ideational metafunction. These inferences indicate that further exploration of a larger data set is worth pursuing. Such studies would provide deeper insights helping to distinguish between online material which supports terrorism and that which opposes it, as well as facilitating the further development of multimodal social semiotic approaches to image and text relations.

East Asian imagery resonates throughout Martin Heidegger's writings. In this exploration of the connections between Daoism and his thought, an international team of scholars consider why the Daodejing and Zhuangzi were texts he returned to repeatedly and the extent Heidegger adhered to Daoism's core doctrines. They discuss how Daoist thought provided him with a new perspective, equipping him with images, concepts, and meanings that enabled him to continue his questioning of the nature of being. Exploring the environment, language, death, temporality, (...) aesthetics, and race from the groundlessness of non-being, oneness, and the Way, they illustrate how these themes reverberate with ontological, spiritual, and epistemological potential. A lesson in the art of Daoist and cross-cultural ways of thinking, this collection marks the first sustained analysis of the influence of classical Daoism on a major 20th-century German philosopher.

This paper introduces the concept of nothingness as used in classical Daoist philosophy, building upon contemporary scholarship by offering a uniquely phenomenological reading of the term. It will be argued that the Chinese word wu bears upon two planes of reality concurrently: as ontological nothingness and as ontic nonbeing. Presenting wu in this dyadic manner is essential if we wish to avoid equating it with Dao itself, as many have been wont to do; rather, wu is the mystery that perpetually (...) veils Dao while serving as the root and counter‐balance to being, and yet, Dao also imbues things with wu to the extant that their physical makeup and usefulness, or lack thereof, can be traced back to their source in Dao. This does not only mean that Daoist cosmogony and metaphysics are inherently informed by nothingness/nonbeing instead of being/beings but that it works to unground all moral and epistemological norms in play, a feat no other school of thought in ancient China could accomplish.

Wei-Jin period is characterized by neo-Daoism ( xuanxue 玄學), and J I Kang lived in the midst of this philosophical exploration. Adopting the naturalism of the Zhuangzi , J i Kang expressed his socio-political concerns through the medium of music, which was previously regarded as having moral bearing and rectitude. Denying such rectitude became central for J i Kang, who claimed that music was incapable of possessing human emotion, releasing it from the chains of Confucian ritualism. His investigation into the (...) name and reality of musical expression gave music an “aesthetic turn” lacking in Qin and early Han thought, and by making use of concepts such as natural harmony and spontaneity, J i Kang was able to turn away from the negative aesthetics of earlier thinkers such as H e Yan and W ang Bi to one cherishing the naturalism espoused by Zhuangzi.

This article investigates the concept of time as it is laid forth in the Daoist text, the Zhuangzi 莊子. Arguing that authentic time lies with cosmogony and not reality as envisioned by humanity, the Zhuangzi casts off the ontology of the present-now in favor of the existentially creative negativity of Dao 道. As the pivot of Dao, nothingness not only allows us to side-step the issue of temporal directionality, it reflects the meontological nature of Daoist cosmology in general. Framing time (...) in terms of the motion of nothingness, this paper concludes that the authentic time of Dao reveals itself through the principle of creation qua rest. Experiencing such temporal self-grounding, the sage becomes existentially awakened such that temporal ekstases becomes unfathomable. (shrink)

Macek (2004) highlighted a typology of current concepts of cyberculture. Four different concepts were identified, which are spans utopian, information, anthropological and epistemological concepts of cyberculture. Macek (2004) also highlighted four different periods of the cyberculture and its impacts on netizen. The very first foundations of cyberculture originate at the Massachusetts Institute of Technology (M.I.T.) at the turn of the 1950s and the 1960s. Early cyberculture reached its peak in the late 1970s and in the 1980s. Early cyberculture originates in (...) the American hackers’ subcultures. The second period of cyberculture can be broadly set to the 1970s and the beginning of the 1980s. The beginning of the third period was characterised by a significant transformation at all the levels of early cyberculture, a shift that was related to the accelerated spread of microcomputers and to the development of public computer networks. This fourth period begins at the end of the 1980s and ends in about the middle of the 1990s. (shrink)

Jonathan Edwards has most often been considered in the context of the Puritanism of New England. However, in many ways he was closer to the thinkers of the European Enlightenment. Leon Chai explores the connection, analysing Edwards's thought in light of a number of the issues that preoccupied such Enlightenment figures as Locke, Descartes, Malebranche, and Leibniz.
