Nursing knowledge development and application are influenced by numerous factors within the context of science and practice. The prevailing culture of science along with an evolving context of increasingly technological environments and rationalization within health care impacts both the generation of nursing knowledge and the practice of nursing. The effects of the culture of science and the context of nursing practice may negatively impact the structure and application of nursing knowledge, how nurses practice, and how nurses understand the patients and (...) families for whom they care. Specifically, the nature of critical care and its highly technical environment make critical care nursing especially vulnerable to these potentially negative influences. The influences of the culture of science and the increasingly technical practice context may result in an overreliance on the natural sciences to guide critical care nursing actions and an associated marginalization of the caring relationship in critical care nursing practice. Within this environment, nursing philosophy may not be foundational to nursing actions; rather, the dominant culture of science and the rationalization of health care may be informing nursing practice. As such, the ideology and goals of nursing may not be central to the practice of critical care nursing. The purpose of this paper is to explore the influence of the culture of science on the development of nursing knowledge and theory. Further, we aim to describe the value of using conceptual frameworks, such as Roy's Adaptation Model, as a nursing philosophy to influence the development of person‐centred nursing knowledge and theory to inform critical care nursing practice as it related to the care of patients and families. In doing so, nursing philosophy is situated as foundational for nursing actions. (shrink)

The literature on human and animal learning suggests that individuals attend to and act on cues differently based on the order in which they were learned. Recent studies have proposed that one specific type of learning outcome, the highlighting effect, can serve as a framework for understanding a number of early cognitive milestones. However, little is known how this learning effect itself emerges among children, whose memory and attention are much more limited compared to adults. Two experiments were conducted using (...) different versions of the general highlighting paradigm: Experiment 1 tested 3 to 6 year olds with a newly developed image-based version of the paradigm, which was designed specifically to test young children. Experiment 2 tested the validity of an image-based implementation of the highlighting paradigm with adult participants. The results from Experiment 1 provide evidence for the highlighting effect among children 3–6 years old, and they suggest age-related differences in dividing attention among multiple cues during learning. Experiment 2 replicated results from previous studies by showing robust biases for both image-based and text-based versions of the highlighting task. This study suggests that sensitivity to learning order emerges early through the process of cued attention, and the role of the highlighting effect in early language learning is discussed. (shrink)

Prosody, in motherese as in all forms of language, has a very different form and a very different use than the central lexical, phonological, and syntactic components of language. Whereas the prosodic aspects of motherese probably derive from primate vocalization, this does not help us to understand how the more distinctive parts of language emerged.

This article sets out a formal procedure for determining the probability that God would do a specified action, using our moral knowledge and understanding God as a perfect being. To motivate developing the procedure I show how natural theology – design arguments, the problems of evil and divine hiddenness, and the treatment of miracles and religious experiences as evidence for claims about God – routinely appeals to judgments involving these probabilities. To set out the procedure, I describe a decision-theoretic model (...) for practical reasoning which is deontological so as to appeal to theists, but is designed not to presuppose any substantive moral commitments, and to accommodate normative and non-normative uncertainty. Then I explain how judgments about what we probably ought to do can be transformed into judgments about what God would probably do. Then I show the usefulness of the procedure by describing how it can help structure discussions in natural theology and a-theology, and how it offers an attractive alternative to ‘skeptical theism’.

I argue that the reference for “God” is determined by the definite description “the being that is worthy of our worship.” I describe two desiderata for rival theories of the reference of “God” to meet: accessibility and scope. I explain the deficiencies of a view where God is dubbed “God” and the name passed down by causal chains and a view where “God” picks out the unique satisfier of a traditional definite description. After articulating the “Worship-Worthiness” view, I show how (...) it best satisfies the desiderata. I then respond to some putative counterexamples to the view. (shrink)

Are religious experiences evidence about God's nature? How should we judge between two religious experiences with conflicting contents, when both have passed the tests we would normally use to sort reliable from misleading experiences? Divine Disclosures argues that the best arguments for skepticism about religious experience stem from a lack of a good answer to the second question, and sets out to devise and defend a method for evaluating religious experiences in a way that avoids charges of vicious circularity and (...) lack of precision. On the way, it presents contributions to the use of decision and probability theory in meta-ethics and philosophy of religion, and applies contemporary philosophy of language to method in theology to argue that all parties to debates about God's nature must agree on a root understanding of God as a perfect being.

Cognitive fatigue is a problem for the safety of critical systems as it can lead to accidents, especially during unexpected events. In order to determine the extent to which it disrupts adaptive capabilities, we evaluated its effect on online and anticipatory control. Despite numerous studies conducted to determine its effects, the exact mechanism affected by fatigue remains to be clarified. In this study, we used distribution and electromyographic analysis to assess whether cognitive fatigue increases the capture of the incorrect automatic (...) response or if it impairs its suppression, and whether the conflict adaptation effect is reduced. To this end, we evaluated the evolution of the performance over time during the Simon task, a classic conflict task that elicits incorrect automatic responses. To accentuate the presence of fatigue during the Simon task, two groups previously performed a dual-task with two different cognitive load levels to create two different levels of fatigue. The results revealed that time on task impaired online control by disrupting the capacity to suppress the incorrect response but leaving unaffected the expression of the automatic response. Furthermore, participants emphasized speed rather than accuracy with time on task, with in addition more fast guesses, suggesting that they opted for a less effortful response strategy. As the implementation of the suppression mechanism requires cognitive effort, the conjunction of these results suggests that the deficits observed may be due to disengagement of effort over time rather than reflecting an incapacity to make an effort.

The study examined the influence of the Pond Report on the teaching of medical ethics in the London medical schools. A questionnaire was given to both medical students and college officers. All medical colleges reported that ethics was included in the curriculum. However, from students' replies, it seems that attendance of optional courses is low and that not all current final year medical students have had any formal teaching in medical ethics. Stronger guidelines are necessary to ensure appropriate ethical training (...) in London medical schools. (shrink)

The medial temporal lobe supports both navigation and declarative memory. On this basis, a theory of phylogenetic continuity has been proposed according to which episodic and semantic memories have evolved from egocentric and allocentric navigation in the physical world, respectively. Here, we explored the behavioral significance of this neurophysiological model by investigating the relationship between the performance of healthy individuals on a path integration and an episodic memory task. We investigated the path integration performance through a proprioceptive Triangle Completion Task (...) and assessed episodic memory through a picture recognition task. We evaluated the specificity of the association between performance in these two tasks by including in the study design a verbal semantic memory task. We also controlled for the effect of attention and working memory and tested the robustness of the results by including alternative versions of the path integration and semantic memory tasks. We found a significant positive correlation between the performance on the path integration the episodic, but not semantic, memory tasks. This pattern of correlation was not explained by general cognitive abilities and persisted also when considering a visual path integration task and a non-verbal semantic memory task. Importantly, a cross-validation analysis showed that participants' egocentric navigation abilities reliably predicted episodic memory performance. Altogether, our findings support the hypothesis of a phylogenetic continuity between egocentric navigation and episodic memory and pave the way for future research on the potential causal role of egocentric navigation on multiple forms of episodic memory.

Background Informed consent is a requirement for all research. It is not, however, clear how much information is sufficient to make an informed decision about participation in research. Information on an online questionnaire about childhood development was provided through an unfolding electronic participant sheet in three levels of information. Methods 552 participants, who completed the web-based survey, accessed and spent time reading the participant information sheet (PIS) between July 2008 and November 2009. The information behaviour of the participants was investigated. (...) The first level contained less information than might be found on a standard PIS, the second level corresponded to a standard PIS, and the third contained more information than on a standard PIS. The actual time spent on reading the information provided in three incremental levels and the participants' evaluation of the information were calculated. Results 77% of the participants chose to access the first level of information, whereas 12% accessed the first two levels, 6% accessed all three levels of information and 23% participated without accessing information. The most accessed levels of information were those that corresponded to the average reading times. Conclusion The brief information provided in the first level was sufficient for participants to make informed decisions, while a sizeable minority of the participants chose not to access any information at all. This study adds to the debate about how much information is required to make a decision about participation in research and the results may help inform the future development of information sheets by providing data on participants' actual needs when deciding about questionnaire surveys.

Competing arguments surrounding the relationships between inequalities and labor rights have persisted over time. This paper explores whether labor rights increase or decrease two types of wage inequalities: vertical inequality and horizontal inequality. Vertical inequalities reflect inequalities in wealth or income between individuals, while horizontal inequalities reflect inequalities between social, ethnic, economic, and political groups which are usually culturally defined or socially constructed. By broadening the scope beyond traditional indicators of inequality (i.e., vertical inequality) to include horizontal inequality, we test (...) whether government respect for labor rights can help reduce inequality. We find that as labor rights and practices improve, countries see a decrease in horizontal inequality. Furthermore, as stronger protections for labor rights improve within countries, this also serves to reduce individual levels of inequality (i.e., vertical inequality). (shrink)

The purpose of public and community health is to improve the health of populations or groups rather than concentrating on individuals. This book examines the ethical issues associated with public and community health. The contributors analyse the major ethical issues in public health - prioritisation, public participation, health promotion and screening - all of which reflect current practice in the UK. They examine what health services should be available, who should have access to which health services, what are the best (...) strategies for preventing disease, how can professional and public views be reconciled and when can an individual's health needs override the choice of a community. The contributors apply up-to-date ethical theory to practical examples in public health practice to provide a comprehensive and accessible introduction to the key issues in public health ethics.

Renewed interest in human space exploration has highlighted the gaps in knowledge needed for successful long-duration missions outside low-Earth orbit. Although the technical challenges of such missions are being systematically overcome, many of the unknowns in predicting mission success depend on human behavior and performance, knowledge of which must be either obtained through space research or extrapolated from human experience on Earth. Particularly in human neuroscience, laboratory-based research efforts are not closely connected to real environments such as human space exploration. (...) As caves share several of the physical and psychological challenges of spaceflight, underground expeditions have recently been developed as a spaceflight analog for astronaut training purposes, suggesting that they might also be suitable for studying aspects of behavior and cognition that cannot be fully examined under laboratory conditions. Our objective is to foster a bi-directional exchange between cognitive neuroscientists and expedition experts by (1) describing the cave environment as a worthy space analog for human research, (2) reviewing work conducted on human neuroscience and cognition within caves, (3) exploring the range of topics for which the unique environment may prove valuable as well as obstacles and limitations, (4) outlining technologies and methods appropriate for cave use, and (5) suggesting how researchers might establish contact with potential expedition collaborators. We believe that cave expeditions, as well as other sorts of expeditions, offer unique possibilities for cognitive neuroscience that will complement laboratory work and help to improve human performance and safety in operational environments, both on Earth and in space.

Recently theorists have developed competing accounts of the origins and nature of protolanguage and the subsequent evolution of language. Debate over these accounts is lively. Participants ask: Is music a direct precursor of language? Were the first languages gestural? Or is language continuous with primate vocalizations, such as the alarm calls of vervets? In this article I survey the leading hypotheses and lines of evidence, favouring a largely gestural conception of protolanguage. However, the “sticking point” of gestural accounts, to use (...) Robbins Burling’s phrase, is the need to explain how language shifted to a largely vocal medium. So with a critical eye I consider Michael Corballis’s most recent expression of his ideas about this transition. Corballis’s view is an excellent foil to mine and I present it as such. Contrary to Corballis’s account, and developing Burling’s conjecture that musicality played some role, I argue that the foundations of an evolving musicality provided the means and medium for the shift from gestural to vocal dominance in language. In other words, I suggest that an independently evolving musicality prepared ancient hominins, morphologically and cognitively, for intentional articulate vocal production, enabling the evolution of speech.

In this paper I examine Hugh Burling’s inspiring proposal that the reference of ‘God’ is determined by the description: ‘the being worthy of our worship’. I argue that a more detailed analysis of the notion of being worthy of our worship leads to the conclusion that the proposed description is paradoxical, and cannot fulfill the role Burling would like it to play in determining the reference of the term ‘God’. Subsequently, I provide several examples implying that being worthy of our (...) worship is a necessary condition for any candidate to be the referent of the term ‘God’, but the semantics of ‘God’ is considerably more complicated than Burling takes it to be. Finally, I show that religious people who use the word ‘God’ are either idolatrous or trapped in an apophatic paradox of the reference of ‘God’. (shrink)

Could Christians and Muslims be referring to the same God? Consider Gareth Evans’s causal theory of reference, on which a name refers to the dominant source of information in the name’s “dossier”. I argue that information about experiences, in which God is simply the object of acquaintance, can dominate the dossier. Thus, this "demonstrative" use of names offers a promising alternative avenue by which users of the divine names can refer to the same referent despite having different conceptions of God.
