Social media applications such as Twitter, YouTube and Facebook have attained huge popularity, with more than three billion people and organizations predicted to have a social networking account by 2015. Social media offers a rapid avenue of communication with the public and has potential benefits for communicable disease control and surveillance. However, its application in everyday public health practice raises a number of important issues around confidentiality and autonomy. We report here a case from local level health protection where the (...) friend of an individual with meningococcal septicaemia used a social networking site to notify potential contacts. (shrink)

The purpose of this research is to investigate the effectiveness of Digital Content Marketing on a Mixed Reality training platform environment with the consideration of online purchase intention through social media. E-commerce today encounters several common issues that cause customers to have reservations to purchase online. With the absence of physical contact points, customers often perceive more risks when making purchase decisions. Furthermore, online retailers often find it hard to engage customers and develop long-term relationships. In this research, a Structural (...) Equation Model is proposed to examine the efficacy of DCM from both immediate and long-term OPI. The results examine whether adopting DCM on an MR training platform environment through social media brings positive results in OPI. Empirical research was carried out through online questionnaires collected in 2021 and 2022. A total of 374 questionnaires were qualified for data analysis in this study, conducted with IBM SPSS and AMOS. The results imply that DCM is critical to stimulating both immediate and long-term OPI. The immediate OPI is positively affected by increasing perceived value through MR in DCM. Regarding the long-term OPI, increased customer engagement with DCM under MR environment can cultivate brand trust and significantly affect the long-term OPI. (shrink)

How many words is a bilingual 2-year-old supposed to know or say in each of her languages? Speech and language therapists or researchers lack the tools to answer this question, because several factors have an impact on bilingual language skills: gender, amount of exposure, mode of acquisition, socio-economic status and the distance between L1 and L2. Unfortunately, these factors are usually studied separately, making it difficult to evaluate their weight on a unique measure of vocabulary. The present study measures the (...) contribution of the following factors to the vocabulary scores of bilingual toddlers: i) gender; ii) sibling ranking; iii) relative amount of exposure to each language; iv) mode of exposure; v) SES; vi) linguistic distance; vii) language spoken between parents. Close to the child’s second birthday, parents of 278 UK-based bilinguals completed successively: a 100-word version of the Oxford-CDI, the CDI in the child’s Additional Language, a family questionnaire, and the Language Exposure Questionnaire. Thirty-six British-English-AL pairs were considered, with languages contrasted on a second-language-learning scale : for example, Dutch and French are close to British-English, while Polish or Cantonese are more distant. Data from the corpus were included in two mixed-effect models, one with the English scores in comprehension as the dependent variable, and the other with production scores. The seven factors listed above were included as predictors. The amount of English exposure was the strongest predictor of comprehension scores = 9.35, p <.005, β = 0.02, t = 3.08, p <.005), followed by the language that parents speak between themselves = 14.94, p <.001, β = 1.37, t = 3.76, p <.0005), linguistic distance = 6.92, p <.01, β = -0.74, t = -2.66, p <.01) and age = 4.86, p <.05, β = 0.55, t = 2.17, p <.05). In production, gender = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), amount of exposure to English = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), the language that parents speak between themselves = 11.85, p <.005, β = 1.09, t = 3.41, p <.001), and the mother’s occupation = 4.51, p <.05, β = 0.63, t = 2.13, p <.05) were the significant predictors. The more English parents use to address one another, the more English words the child says and understands. This surprising result could be simply explained by the fact that parents who speak English together are also more likely to speak English to their child. The main results of this study is that linguistic distance is a powerful predictor of toddlers’ vocabulary in English, with children learning two close languages growing their vocabulary faster than those learning distant languages.

Background Protecting a person’s right to privacy and confidentiality is important in healthcare services. As future health professionals, nursing students should bear the same responsibility as qualified health professionals in protecting patient privacy. Objectives To investigate nursing students’ practices of patient privacy protection and to identify factors associated with their practices. Research design A cross-sectional study design was adopted. A two-part survey was used to collect two types of data on nursing students: (1) personal characteristics, including demographics, clinical experience and (...) use of information and communication technology and social media and (2) practice of patient privacy protection, collected using the Patient Privacy Scale. Participants and research context: A total of 319 nursing students aged 18 or above, studying pre-registration nursing programmes and who had attended at least one block of clinical placement, were recruited from a university in Hong Kong. Ethical considerations The study received ethical approval from the Survey and Behavioural Research Ethics Committee of the Chinese University of Hong Kong. The participants were informed of the study aim and written consent was obtained before completing the survey. Findings: The mean total score on the Patient Privacy Scale was 119.7 out of 135. Nursing students who were regular users of Instagram and those who had never taken photographs with patients and hence did not need to obtain patient consent were associated with better practices of patient privacy protection (higher total scores on the Patient Privacy Scale). Conclusions The findings improve our understanding of nursing students’ practice of patient privacy protection and the associated factors. This will inform the development and revision of current strategies to enhance nursing students’ practice of patient privacy protection, especially their use of social media. (shrink)

Experiments with the simple pendulum are easy, but its motion is nevertheless confounded with simple harmonic motion. However, refined theoretical models of the pendulum can, today, be easily taught using software like CALCODE. Similarly, the cycloidal pendulum is isochronous only in simplified theory. But what are theoretically equal intervals of time? Newton accepted Barrow’s even tenor hypothesis, but conceded that ‘equal motions’ did not exist – the refutability of Newtonian physics is independent of time measurement. However, time measurement was the (...) key difficulty in reconciling Newtonian physics with electrodynamics. On Poincaré’s criterion of convenience, equal intervals of time ought be so defined as to make the enunciation of physics simple. Hence he postulated constancy of the speed of light. (The Michelson–Morley experiment was not critical.) The theory of relativity followed. But does there exist a proper clock? (shrink)

The aim of this study was to test red - green dichromats' ability to discriminate between illuminant and surface-reflectance changes in natural scenes. Stimuli were simulations of natural scenes presented on a colour monitor with 10-bit resolution per gun. The natural scenes were obtained with a fast hyperspectral imaging system. Six different scenes (including rocks, foliage, and buildings) were tested. In each trial, two images were presented in sequence, each for 1 s, with no interval. The images differed in the (...) phase of daylight on the scene: first with correlated colour temperature 25 000 K, then 6 700 K. The spectral reflectance of a region in the second image was changed randomly, consistent with a local change in daylight. The observer's task was to decide whether a particular surface in the successive images was the same (pure illuminant change) or different (illuminant change with a surface-reflectance change). The performance of four deuteranopes and five protanopes varied considerably across the scenes tested, with mean colour constancy indices (± 1 SEM) of 0.48 (± 0.13) and 0.19 (± 0.10), respectively (1.0 representing ideal performance). Deuteranopes seemed less disadvantaged than protanopes, performing close to normal with some scenes. (shrink)

Are mystical experiences primarily formed by the mystic's cultural background and concepts, as modern day "constructivists" maintain, or do mystics in some way transcend language, belief, and culturally conditioned expectations? Do mystical experiences differ in the different religious traditions, as "pluralists" contend, or are they identical across cultures? Twelve contributors here attempt to answer these questions through close examination of a particular form of mystical experience, "Pure Consciousness"--the experience of being awake but devoid of intentional content for consciousness. The contributors (...) analyze pure consciousness and other mystical experiences from historical Hindu, Buddhist, Christian, and Jewish sources, as well as from modern mystics. They demonstrate that pure consciousness poses serious conceptual problems for a contructivist understanding of mysticism. Revealing the inconsistencies and inadequacies of current models, they make significant strides towards developing new models for the phenomenon of mysticism, breaking new ground for our understanding of mysticism and of human experience in general.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Method in Ancient PhilosophyDavid K. GliddenJyl Gentzler, editor. Method in Ancient Philosophy. Oxford: Clarendon Press, 1998. Pp. viii + 398. Cloth, $72.00.The fifteen papers in this collection constitute revisions of conference proceedings and reflect the varied interests of participants. The ensemble exhibits a thoroughly modern methodology. Whatever and however various ancient methods of philosophy may have been, in Anglo-American scholarship it is standard practice to first address established (...) scholarly interpretations as the primary entry point to critical discussionóoften displacing antiquity with a critical vocabulary of philosophical modernity. Scholars may come to understand each other better, but at the risk of asking the wrong questions or sacrificing ancient texts themselves as mere means of producing papers.Most scholars are progressives. They believe philosophy has advanced past the comparatively primitive wisdom of antiquity, and so such scholars feel perfectly entitled to make better sense of ancient texts, by patiently explaining what the ancients would have meant had they only been able to get it right. There are, of course, exceptions. And some papers in this collection suggest deeper faith in our philosophic fathers. So, the battle between the ancients and the moderns is joined once more, between those who would adorn their papers with footnotes for their peers and those who would attempt more anthropological an inquiry into ancient philosophic practices.Ian Mueller and Robert Bolton each address the same passage in Plato's Phaedo, both beginning with an article from Vlastos, first published in 1969. Mueller thoughtfully explores three different yet related accounts of what we might call scientific method in explaining Plato's views on natural change. Bolton wonders whether scholars are asking the wrong questions. Patricia Curd attempts a progressivist account of Eleatic thought, notwithstanding her recognition of the paucity of ancient sources. Complete with elaborately numbered sentences, Gail Fine focuses primarily on Burnyeat (1976) on Plato on Protagoras. Constance Meinwald presents a rather near-sighted account of two passages in the Philebus that employ the peras-apeiron distinction, with a view toward Plato's allegedly modernist mathematization of understanding. Lesley Brown revisits five pages of the Sophist that were hotly debated in the 1960s. With charity and elegance, she offers several plausible solutions to puzzles posed by previous scholars. Sometimes time smoothes over differences.A. A. Long's essay on Plato's presentation of Socrates in the Theaetetus might appear more philosophically anthropological. Yet Long reveals progressive sympathies, suggesting that Plato dispatches Socrates in the Theaetetus, so as to prepare the way for a more rigorously academic form of philosophizing, such as that exhibited in the Sophist. [End Page 111] In this way, Long speculates, Plato abandoned practical ethics for the academic life of research, so familiar to university professors and conference participants. It might be hard to square such speculation with Plato's Laws and the reception of Plato's writings among his own contemporaries. Still, Socrates' shifting role in Plato's dialogues is well worth pondering.By comparison, T. H. Irwin's contribution is wonderfully old-fashioned. His paper addresses the background knowledge to be presumed by ancient readers of Plato's dialogues and how that knowledge is artfully put to use in Plato's depiction of Socrates' reflections on the unity of virtue. By speculating on Plato's relation to his ancient readers, Irwin displaces many modernist preoccupations, though not without himself falling victim to that peculiar scholarly obsession of dating Plato's dialogues by their doctrines.With characteristic conservatism, Gisela Striker cautions scholars not to over-read Aristotle's Prior Analytics. While that extraordinary work may have deep implications for the history of formal logic, it probably was instead intended to be part of a general account of argument. In a similar vein, Charlotte Witt attempts to rescue Aristotle from scholars who would delimit Aristotle's multifarious uses of the "for the sake of" explanation, which altogether pervade his metaphysics, physics, biology and ethics. Yet, Witt soon finds herself competing in a contest over interpretive distinctions, a sport that will certainly never capture Aristotle's own authorial intentions.Facing another mass of scholarship, in this case on Aristotle's dialectic, C. D. C. Reeve sensibly attempts to... (shrink)

Many people in the animal welfare communityhave argued that the use of nonhuman animals inmedical research is necessarily based onspeciesism, an unjustified prejudice based onspecies membership. As such it is morally akinto racism and sexism. This is misguided. Thecombined capacities for autonomy and sentiencewith the obligations derived from relationssupport a morally justifiable rationale forusing some nonhuman animals in order to limitthe risk of harm to humans. There may be a fewcases where it is morally better to use a neversentient human (...) than a sentient animal, butthese cases are few and would not fulfill thecurrent need for research subjects. The use ofnonautonomous animals instead of humans inrisky research can be based on solid moralground. It is not necessarily speciesism. (shrink)

Hilde Lindemann’s Holding and Letting Go is a valuable addition to the literature on personhood and identity. Like most such texts, it recognizes the ambiguity of the concepts. However, while other texts then try to clarify and fix the ambiguity, Lindemann goes in another direction. She embraces it by presenting and examining the many ways in which practices of social connection, interaction, and disconnection shape, preserve, and even damage an individual’s personal and social identity.Lindemann breaks with classic texts on identity, (...) which tend to move from the particular to proposing and supporting a specific definition of an objective concept of identity, usually incorporating moral agency. Using well-crafted... (shrink)

Rethinking Reprogenetics by Immaculada de Melo-Martin has at its heart a desire to spark discussion about the foundations of our right to reproduce. While many of the arguments are familiar in feminist ethics, de Melo-Martin's text is a useful addition in that she is focusing on the development and application of genetic technology toward reproductive ends, including the ends of transhumanism. Particularly, de Melo-Martin is skeptical about claims that genetic reproduction is a need or right deserving of social resources. This (...) is particularly an issue when genetic reproduction requires public resources to do it or as a consequence of it. She raises questions about whether the desire to have genetically related... (shrink)

In normative decision theory, the weight of an uncertain event in a decision is governed solely by the probability of the event. A large body of empirical research suggests that a single notion of probability does not accurately capture peoples' reactions to uncertainty. As early as the 1920s, Knight made the distinction between cases where probabilities are known and where probabilities are unknown. We distinguish another case –- the unknowable uncertainty –- where the missing information is unavailable to all. We (...) propose that missing information influences the attractiveness of a bet contingent upon an uncertain event, especially when the information is available to someone else. We demonstrate that the unknowable uncertainty –- falls in preference somewhere in between the known and the known uncertainty. (shrink)

Welcome to the world of cutting-edge math, physics, and neuroscience, where the search for the ultimate vacuum, the point of nothingness, ground zero of theory, has rendered the universe deep, rich, and juicy. "Modern physics has animated the void," says K. C. Cole in her entrancing journey into the heart of Nothing. Every time scientists and mathematicians think they have reached the ultimate void, new stuff appears: a black hole, an undulating string, an additional dimension of space or time, repulsive (...) anti-gravity, universes that breed like bunnies. Cole's exploration at the edge of everything is as animated and exciting as the void itself. Take Cole's hand on this adventure into the unknown, and you'll come back informed, amused, and excited.

The challenges public comprehensive universities face today are expanding—they have been challenged to enroll and graduate more students, adopt new technologies that lower cost without sacrificing quality, and align program and curricular offerings with the skills that employers require. While these universities have a long history of adapting to change, today’s environment will likely test the capabilities of even the most adaptive institutions. This volume assembles a team of experts from a variety of disciplines to examine both the history of (...) the comprehensive university and what lies ahead. Overall, the book grapples with such questions as: How do these institutions adapt to serve the growing population of non-traditional students? How well do they prepare graduates for the labor market? Can partnerships between community colleges and comprehensive universities bolster student success? The University Next Door draws much-needed attention to a set of institutions that has historically received little notice, yet play an important role in meeting our new attainment goals and helping the American economy grow. Book Features: Examines the role of comprehensive universities from start to finish—their history and future. Uses empirical analysis to explore complex questions about which students choose these universities and why. Explores how these institutions might struggle under a federal ratings system such as the one proposed by President Obama. Discusses how these institutions can better monitor the needs of the economy and better educate students to fill those needs. Provides recommendations to inform future decisions about higher education policy. (shrink)

This paper investigates the emotional import of literary devices deployed in fiction. Reflecting on the often-favored approach in the analytic tradition that locates fictional characters, events, and narratives as sources of readers’ emotions, I attempt to broaden the scope of analysis by accounting for how literary devices trigger non-cognitive emotions. I argue that giving more expansive consideration to literary devices by which authors present content facilitates a better understanding of how fiction engages emotion. In doing so, I also explore the (...) somatic dimension of reading fiction. (shrink)

Some practical problems in the teaching of ethics to medical students are described. The definition of the objectives of the course remains the central aspect, and is more important than the specific content. The use of student projects, buzz groups, case histories and discussion points is described. There is a need for student assessment or examination at the end of the course. The teachers require a broad background in philosophy, clinical medicine and teaching skills. The learning of the teachers may (...) be as important as that of the students. (shrink)

Quality of life is a difficult concept to define and to measure. An hypothesis is proposed which suggests that the quality of life measures the difference, or the gap, at a particular period of time between the hopes and expectations of the individual and that individual's present experiences. Quality of life can only be described by the individual, and must take into account many aspects of life. The approach is goal-orientated, and one of task analysis. The hypothesis is developed in (...) a diagramatic way, and several methods of testing the hypothesis suggested. (shrink)

In their influential paper “The extended mind”, Andy Clark and David Chalmers argue for the possibility of the extended mind. Based on Clark and Chalmers’s views, Stephen Hetherington argues in his paper “The extended knower” that there are extended knowers, provided epistemic externalism holds. He also uses the argument and its conclusion to criticize Baron Reed’s scepticism in the paper “The long road to skepticism” : 236–262, 2007). In this chapter, I argue that both Hetherington’s notion of the extended knower (...) and his argument are problematic. This is because the conceptual intelligibility of his notion of the extended knower entails the highly counterintuitive consequence that, in some cases, some negative entities would have to be constitutive of the extended knower. I also show that Hetherington’s criticism of Reed’s scepticism is not successful, and that there is no reason to believe that Clark and Chalmers would hold that there is the extended knower in Hetherington’s sense.

Historical case studies of scientific concepts are a useful medium for showing how scientific ideas originate and how they change over time. They are thus a useful tool for conveying knowledge about the nature of science. This paper focuses on the concepts of heat and temperature and discusses some issues related to choosing the content for a historical case study which incorporates not only nature of science perspectives but understandings related to what we know about the teaching and learning of (...) these concepts. The case study is designed for first-year university chemistry students as an introduction to their study of thermodynamics. The paper includes a general chemistry textbook analysis of the heat and temperature concepts and a discussion of the caloric theory of heat, thermometry, and a brief survey of how the energy concept transformed our understanding of heat and temperature.

I Propose to re-explore here some aspects of a very shop-worn question: ‘Was Hobbes in any sense an atheist?’ Three centuries ago, Hobbes's personal security in part depended on the way his contemporaries answered this question; today, the validity of several current accounts of his philosophy are similarly bound up with it. These accounts vary extraordinarily, all the way from Polin's confident assertion that ‘ pour qui sait lire entre les lignes, … c'est ľatheísme qui triomphe implicitement ’, to Taylor's (...) equally firm belief that ‘a certain kind of theism is necessary to make [Hobbes's] theory work.’ 1 And now the latest of the Taylorians, Prof. Howard Warrender, has published his book The Political Philosophy of Hobbes , in which Hobbes's statements regarding the place of God are again treated as an essential part of his theory; and the charge explicitly made, that there are no sound grounds for regarding them as ‘the product of confusion or pretence on Hobbes's part’.

Resource allocation is a central part of the decision-making process in any health care system. Resources have always been finite, thus the ethical issues raised are not new. The debate is now more open, and there is greater public awareness of the issues. It is increasingly recognised that it is the technology which determines resources. The ethical issues involved are often conflicting and relate to issues of individual rights and community benefits. One central feature of resource allocation is the basing (...) of decisions on the outcomes of health care and on their subsequent economic evaluation. The knowledge base is therefore of great importance as is the audit of results of clinical treatment. Public involvement is seen as an integral part of this process. For all parts of the process, better methodologies are required. (shrink)

The hypothesis that values change and evolve is examined by this paper. The discussion is based on a series of examples where, over a period of a few decades, new ethical issues have arisen and values have changed. From this analysis it is suggested that there are a series of core values around which most people would agree. These are unlikely to change over long time periods. There are then a series of secondary or derived values around which there is (...) much more controversy and within which differences of view occur. Such changes need to be documented if we are to understand the process involved in the evolution of differences in ethical views. (shrink)

Upshot: The commentaries concentrate mostly on ontological issues but overlook the main epistemological argument in my target article. This argument refers to the conditions that make cognition possible, and to the limits of cognition. These are important for two reasons: they have ontological consequences and they limit the theory’s contingency.

Context: In the literature concerning the theory of social systems, interest in epistemological and ontological questions has increased in recent years. The controversies regarding a realist vs. constructivist interpretation of Luhmann’s theory, as well as the concept of many realities that correspond to many ontologies, deserve attention. Problem: The paper discusses interrelated ontological and epistemological problems in Luhmann’s systems theory, such as ontology and de-ontologization, realism vs. constructivism, contingency and its limits and one vs. many realities. Method: The paper proposes (...) an interpretation, according to which systems theory is based on an epistemology - radical operative constructivism. Results: Luhmann is not a realist. The last word belongs to radical operative constructivism, and naïve realism with reference to social systems has only a preliminary, methodological significance. However, taking a position in the dispute between realism and constructivism inevitably involves an ontological “vocabulary,” that is, usage of the reality/construction distinction. Furthermore, operative constructivism formulates the necessary conditions of the possibility of cognition, which limit the contingency of the theory and constitute one reality that is a construction of systems theory. Luhmann rejects ontology, but he does not renounce epistemology, and consequently the project of de-ontologization remains incomplete. Implications: The paper offers a new, coherent interpretation of ontological and epistemological questions in Luhmann’s theory, and also throws light on some problems of radical constructivism in general, such as the ontological implications of epistemology or the constructivist self-reference of theories. Key words: Radical operative constructivism, social systems, Luhmann, ontology, reality, contingency. (shrink)
