Recent studies show that racism still exists in the American medical profession, the fact of which legitimizes the historically long-legacy of mistrust towards medical profession and health authorities among African Americans. Thus, it was suspected that the participation of black patients in end-of-life care has always been significantly low stemmed primarily from their mistrust of the medical profession. On the other hand, much research finds that there are other reasons than the mistrust which makes African Americans feel reluctant to the (...) end-of-life care, such as cultural-religious difference and genuine misunderstanding of the services. If so, two crucial questions are raised. One is how pervasive or significant the mistrust is, compared to the other factors, when they opt out of the end-of-life care. The other is if there is a remedy or solution to the seemingly broken relationship. While no studies available answer these questions, we have conducted an experiment to explore them. The research was performed at two Philadelphia hospitals of Mercy Health System, and the result shows that Black patients’ mistrust is not too great to overcome and that education can remove the epistemic obstacles as well as overcome the mistrust.

ABSTRACTFilm clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can (...) be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validit... (shrink)

The majority of antimicrobials that are produced are administered to animals, particularly food animals. While the overall impact of antimicrobial use in animals on antimicrobial resistance in humans and the environment is unclear, it undeniably has a role. Yet, some degree of antimicrobial use in animals is necessary for animal health and welfare purposes. Balancing the benefits and risks of antimicrobial use in animals is challenging because of the complexity of the problem and limitations in available data. However, a range (...) of measures can be implemented to reduce, refine and optimize antimicrobial use in animals, with a goal of minimizing the impact on human and environmental health while maintaining necessary therapeutic use in animals. A pandemic instrument can provide the necessary foundation for the whole-of-society and whole-of government One Health approach that is required to strengthen surveillance, communication, collaboration, and action.

Drawing on implicit leadership theory and the mindfulness literature, we propose that perceived authentic leadership mediates the relationship between follower mindfulness and follower well-being. Leader mindfulness plays a moderating role in this process. We validated these hypotheses with the two-wave data from 56 leaders and 275 followers in two private enterprises located in China. We used Mplus 8.0 to test our hypotheses. Consistent with our hypotheses, the results showed that perceived authentic leadership mediated the positive relationship between follower mindfulness and (...) follower well-being. Higher leader mindfulness enhanced the effect of follower mindfulness on perceived authentic leadership, and also strengthened the indirect effect of follower mindfulness on follower well-being via perceived authentic leadership. The theoretical and managerial implications are further discussed in the light of these findings. (shrink)

We sought to expand on the concept of the moral self to include not just the duty to develop the moral self but the moral duty to develop the self in both moral and non-moral ways. To do this, we focused on how leaders can promote a climate in which individuals feel a sense of duty to develop themselves for the betterment of the team and organization. In our theoretical model, duty orientation plays a key role in determining whether followers (...) will seek performance feedback to develop their work selves. We hypothesized that followers with ethical leaders would experience a greater sense of duty to improve themselves and would therefore be more likely to seek and less likely to avoid leader feedback. Drawing on social learning theory, we hypothesized that duty orientation would mediate the relationship between ethical leadership and feedback-seeking/feedback-avoiding behavior, expert power would moderate the relationship between ethical leadership and duty orientation such that duty orientation would be higher when followers perceived their leader to be both highly ethical and competent, and expert power would moderate the indirect effect of ethical leadership on feedback-seeking/feedback-avoiding behavior through duty orientation. We tested our hypotheses using a sample of 249 followers across two waves of data collection. Results suggest that ethical leadership and leader competence interact to drive followers’ duty orientation, thereby reducing followers’ feedback-avoiding behaviors. Further, ethical leadership had a direct positive relationship with followers’ feedback-seeking behaviors. (shrink)

Tissue P systems with evolutional communication rules are computational models inspired by biochemical systems consisting of multiple individuals living and cooperating in a certain environment, where objects can be modified when moving from one region to another region. In this work, cell separation, inspired from membrane fission process, is introduced in the framework of tissue P systems with evolutional communication rules. The computational complexity of this kind of P systems is investigated. It is proved that only problems in class P (...) can be efficiently solved by tissue P systems with cell separation with evolutional communication rules of length at most, for each natural number n≥1. In the case where that length is upper bounded by, a polynomial time solution to the SAT problem is provided, hence, assuming that P≠NP a new boundary between tractability and NP-hardness on the basis of the length of evolutional communication rules is provided. Finally, a new simulator for tissue P systems with evolutional communication rules is designed and is used to check the correctness of the solution to the SAT problem. (shrink)

Over the last few years, a new methodology to address the P versus NP problem has been developed, based on searching for borderlines between the nonefficiency of computing models and the presumed efficiency. These borderlines can be seen as frontiers of efficiency, which are crucial in this methodology. “Translating,” in some sense, an efficient solution in a presumably efficient model to an efficient solution in a nonefficient model would give an affirmative answer to problem P versus NP. In the framework (...) of Membrane Computing, the key of this approach is to detect the syntactic or semantic ingredients that are needed to pass from a nonefficient class of membrane systems to a presumably efficient one. This paper deals with tissue P systems with communication rules of type symport/antiport allowing the evolution of the objects triggering the rules. In previous works, frontiers of efficiency were found in these kinds of membrane systems both with division rules and with separation rules. However, since they were not optimal, it is interesting to refine these frontiers. In this work, optimal frontiers of the efficiency are obtained in terms of the total number of objects involved in the communication rules used for that kind of membrane systems. These optimizations could be easier to translate, if possible, to efficient solutions in a nonefficient model. (shrink)

This article aims to explore the complex issue of the emotive effect of Christian songs. It is based mainly on a literature survey, using sources both from Christian hymnology and musicology. It also uses illustrative examples from three informal surveys in congregations on the reasons particular songs are favourites. The point is made that exploring this issue scientifically is very complex as there are so many variables in people’s appreciation of songs. Some of these elements are discussed, such as the (...) effect of the external setting in which people experience a song, factors important in the appreciation of a text, such as poetic quality and knowledge of the author’s background. Other factors are the emotive quality and level of difficulty of a tune and in what time this style was popular. Then there are the internal factors, such as the link of a song with group identity and special memories. Some of the survey results corroborate the pointers in the literature for what makes certain songs particularly emotionally appealing. Some of these were a preference for musical styles popular in one’s youth, the importance of relationships with significant others for forming favourites and the important element of memory in the emotional impact of songs. Concluding pointers for worship include motivating for different styles of music in worship and carefully finding those songs in each new musical genre, which have the potential for sustaining today’s youth into the future.Contribution: This article makes a contribution in what is a complex and often emotionally charged issue in congregations: Worship styles and musical preferences. It argues for the importance of using different musical styles and bringing the generations together. (shrink)

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

Academic resilience is evident in students who are living in vulnerable environments, yet achieve success in academic outcomes. As a result, substantial attention has been devoted to identifying the factors associated with academic resilience and supporting students to be resilient. This study used the Classification and Regression Tree and Multilevel Logistic Regression modeling to identify the potential factors related to students’ academic resilience. Using these tools, the study analyzed the B-S-J-G sample in PISA 2015. The variables that significantly predicted whether (...) a student is disadvantaged and resilient or not resilient were shown to be: Proportion of teachers in school with master’s degrees, Proportion of teachers in school with bachelor’s degrees, Environmental awareness, Science learning time per week, Number of learning domains with additional instruction, and Students’ expected occupational status. These findings may enlighten governments, teachers, and parents on ways to assist students to be resilient. (shrink)

Infant and young child electrophysiology studies have provided information regarding the maturation of face-encoding neural processes. A limitation of previous research is that very few studies have examined face-encoding processes in children 12–48 months of age, a developmental period characterized by rapid changes in the ability to encode facial information. The present study sought to fill this gap in the literature via a longitudinal study examining the maturation of a primary node in the face-encoding network—the left and right fusiform gyrus. (...) Whole-brain magnetoencephalography data were obtained from 25 infants with typical development at 4–12 months, and with follow-up MEG exams every ∼12 months until 3–4 years old. Children were presented with color images of Face stimuli and visual noise images that served as Non-Face stimuli. Using distributed source modeling, left and right face-sensitive FFG evoked waveforms were obtained from each child at each visit, with face-sensitive activity identified via examining the difference between the Non-Face and Face FFG timecourses. Before 24 months of age the face-sensitive FFG M290 response was the dominant response, observed in the left and right FFG ∼250–450 ms post-stimulus. By 3–4 years old, the left and right face-sensitive FFG response occurred at a latency consistent with a face-sensitive M170 response ∼100–250 ms post-stimulus. Face-sensitive left and right FFG peak latencies decreased as a function of age, and with an adult-like FFG latency observed at 3–4 years old. Study findings thus showed face-sensitive FFG maturational changes across the first 4 years of life. Whereas a face-sensitive M290 response was observed under 2 years of age, by 3–4 years old, an adult-like face-sensitive M170 response was observed bilaterally. Future studies evaluating the maturation of face-sensitive FFG activity in infants at risk for neurodevelopmental disorders are of interest, with the present findings suggesting age-specific face-sensitive neural markers of a priori interest.

Then I saw between the throne and the four living creatures and (...) among the elders a Lamb standing as if it had been slaughtered.—Revelation 5:5–6In an interview with Markus Müller, René Girard asserts the importance of taking into account the apocalypticism of Christianity. Apocalypse, Girard reminds us, "means revelation: apocalypto means to open up and to show the truth. But it also means absolute violence, so the apocalypse is a violent revelation and a revelation of violence" (Girard 1996). That the Revelation is a violent revelation has been well established. Despite textual evidence that would beg those who approach the text to do just the opposite, readers have fixated on the violence of the Revelation since its inception, finding in it God's final retribution against those who persecute the Church.1 Commentators such as Dennis E. Johnson, William Hendricksen, and George Elden Ladd have produced recent, full-length commentaries that champion the appearance of a Christ in Revelation ready to establish himself as a military champion and exact his revenge on those who persecute him (see, for example, Johnson 2001; Hendricksen 1998; and Ladd 1993). These accounts, and those that follow suit, are blinded by the violent revelation of John's apocalyptic narrative and fail to see the poem's revelation of violence—the other, prophetic half of what Girard rightly contends exists in Christian apocalypse.This error is understandable to some extent. Read in its own light and apart from the Gospel revelation as understood by those familiar with mimetic [End Page 99] theory, one has no hermeneutical principle for recognizing the end to which John is writing. The victims of the text can be ignored in the precise way that all victims are disregarded when the scapegoat mechanism functions properly. Such should not be the case in the Revelation, though, a text in which the scapegoat mechanism is exposed and pushed to its logical conclusions. John offers his reader a glimpse into the way this mechanism will function when all that is left is wall-to-wall violence, when one is left with only two alternatives: succumb to the mechanism and reciprocate its violence, or extricate oneself through nonreciprocation (and potentially die).In the margins of the violent revelation in John's apocalyptic vision, a revelation of violence emerges that can expose humankind's potential to annihilate itself and the mechanism with which it will do so. When read through the lens of mimetic theory, one discovers that John's narrative delivers a revelation of violence, an explicit naming and unmasking of the sacrificial mechanism that can capture for the reader not only the machinations of the sacrificial apparatus but one's own potential participation in it as well. As such, the poem can posit itself as a commandment (a Thou-shall-not-murder) that ultimately refuses the temptation to respond to violence in violence.The fact that John uses the apocalyptic to present this directive should not be surprising. Girard writes: "Only through the mediation of the scapegoat mechanism can violence become its own remedy, and the victimage mechanism can only be triggered by the frenetic paroxysm of the 'crisis.' This means that the violence, having lost its vitality and bite, will paradoxically be more terrible than before its decline. As the whole of humanity makes the vain effort to reinstate its reconciliatory and sacrificial virtues, this violence will without doubt tend to multiply its victims, just as happened in the time of the prophets" (Girard 1978, 195–96). While Girard's commentary on biblical eschatology and apocalypse refers mainly to the scapegoat mechanism as it applies to and is revealed in the Gospel texts, we see the immediacy and the frenzy of the apocalyptic and the ubiquitous violent mimetic appropriations also performed in John's Revelation.2 John captures...

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Picture a beautiful May afternoon here in Ireland, when the sun shines, all the hedgerows are in bloom, and the blackbirds and the thrushes fill the air with song. Then allow a cold scientific mind to dissect this scene, and the warmth and the glow of the evening quickly disappears. He will explain the sunshine as electromagnetic radiation, the varied tints of the flowers as due to the partial absorption of the light’s rays, the flowers themselves as collections of (...) atoms and molecules, and the singing of the birds as vibration of the air-molecules. It is a repelling, denuded description of the scene, and we instinctively shrink from it. (shrink)

I propose an adjunct to the two models presented in the target articles, a function of music that is ubiquitous and would have solved a clear adaptive problem, that of transmitting important survival information among pre-literate humans. This class of knowledge songs uniquely preserved cultural, botanical, medical, safety, and practical information that increased the adaptive fitness of societies.

While the Bhagavad Gītā is an acknowledged treasure of world spiritual literature, few people know a parallel text, the Īśvara Gītā. This lesser-known work is also dedicated to a god, but in this case it is Śiva, rather than Kṛṣṇa, who is depicted as the omniscient creator of the world. Andrew J. Nicholson’s Lord Śiva’s Song makes this text available in English in an accessible new translation. A work of both poetry and philosophy, the Īśvara Gītā builds on the (...) insights of Patañjali’s Yoga Sūtra and foreshadows later developments in tantric yoga. It deals with the pluralistic religious environment of early medieval India through an exploration of the relationship between the gods Śiva and Viṣṇu. The work condemns sectarianism and violence and provides a strategy for accommodating conflicting religious claims in its own day and in our own. (shrink)

This paper introduces the reconstitutor as a comprehensive unit of heredity within the context of evolutionary research. A reconstitutor is the structure resulting from a set of relationships between different elements or processes that are actively involved in the recreation of a specific phenotypic variant in each generation regardless of the biomolecular basis of the elements or whether they stand in a continuous line of ancestry. Firstly, we justify the necessity of introducing the reconstitutor by showing the limitations of other (...) evolutionary conceptions of the unit of heredity, such as the replicator, the reproducer, and the Darwinian individual. We argue that these conceptions are based on the requirement of lineage formation, which we argue to be unnecessary for the existence of evolutionary heredity. In the second part, we introduce the reconstitutor, which we base on the concept of Stability of Traits, and illustrate how it covers cases of hereditary phenomena not covered by the previous accounts. Secondly, we illustrate how the reconstitutor could serve as a platform to rethink ecological inheritance and other forms of inheritance that have been recently introduced under the song/singer model of evolution.

This article explores the interrelationships between Christian choruses and South African songs of the struggle, which sometimes used the same tunes. The development of each genre is explained and the interrelationship between them analysed. One example is studied in more detail. Songs deeply influence people, be it in their faith or in their political action. A critical awareness of how these songs functioned and continue to function can deepen our understanding of the South African struggle for freedom as well as (...) enriching our praxis today.

Scholars have long been captivated by the parallels between birdsong and human speech and language. In this book, leading scholars draw on the latest research to explore what birdsong can tell us about the biology of human speech and language and the consequences for evolutionary biology. They examine the cognitive and neural similarities between birdsong learning and speech and language acquisition, considering vocal imitation, auditory learning, an early vocalization phase, the structural properties of birdsong and human language, and the striking (...) similarities between the neural organization of learning and vocal production in birdsong and human speech. After outlining the basic issues involved in the study of both language and evolution, the contributors compare birdsong and language in terms of acquisition, recursion, and core structural properties, and then examine the neurobiology of song and speech, genomic factors, and the emergence and evolution of language.
