The concept of a G‐quartet, a unique structural arrangement intrinsic to guanine‐rich DNA, was first introduced by Gellert and colleagues1 over 40 years ago. For decades, it has been uncertain whether the G‐quartet and the structure that it gives rise to, the G‐quadruplex, are purely in vitro phenomena. Nevertheless, the presence of signature G‐rich motifs in the eukaryotic genome, and the plethora of proteins that bind to, modify or resolve this nucleic acid structure in vitro have provided circumstantial evidence for (...) its physiological relevance. More recently, direct visualisation of G‐quadruplex DNA at native telomeres was achieved, bolstering the evidence for its existence in the cell. Furthermore, G‐quadruplex folded telomeric DNA has been found to perturb telomere function and to impede the action of telomerase, an enzyme overexpressed in >85% of human cancers, hence opening up a novel avenue for cancer therapy in the form of G‐quadruplex stabilising agents.

This research project defines the concept of an ethical incident pit and explores how qualitative and quantitative research into corporate ethical failurescan be conducted using this concept. Factors on an organizational, departmental and individual level are explored.

The neural representation of a repeated stimulus is the standard against which a deviant stimulus is measured in the brain, giving rise to the well-known mismatch response. It has been suggested that individuals with dyslexia have poor implicit memory for recently repeated stimuli, such as the train of standards in an oddball paradigm. Here, we examined how the neural representation of a standard emerges over repetitions, asking whether there is less sensitivity to repetition and/or less accrual of “standardness” over successive (...) repetitions in dyslexia. We recorded magnetoencephalography as adults with and without dyslexia were passively exposed to speech syllables in a roving-oddball design. We performed time-resolved multivariate decoding of the MEG sensor data to identify the neural signature of standard vs. deviant trials, independent of stimulus differences. This “multivariate mismatch” was equally robust and had a similar time course in the two groups. In both groups, standards generated by as few as two repetitions were distinct from deviants, indicating normal sensitivity to repetition in dyslexia. However, only in the control group did standards become increasingly different from deviants with repetition. These results suggest that many of the mechanisms that give rise to neural adaptation as well as mismatch responses are intact in dyslexia, with the possible exception of a putatively predictive mechanism that successively integrates recent sensory information into feedforward processing.

To contribute to the continuing challenge of explaining how managers identify stakeholders and assess their salience, in this article, we chronicle the history, assess the impact, and evaluate the possibilities opened by Mitchell, Agle, and Wood (MAW-1997). We do so through two types of qualitative analysis, and also through utilizing a quantitative network analysis tool. The first qualitative analysis categorizes the major contributions of the most influential papers succeeding MAW-1997; the second identifies and compares the relevant issues with MAW-1997 at (...) the time of initial publication and today. We apply main path analysis, a quantitative tool, to map how this scholarly domain has evolved. These three analyses robustly depict the impact of MAW-1997 and the ensuing scholarly conversation, and they enable us to illustrate the current state and trajectory of stakeholder identification and salience scholarship. We close by discussing pressing topics related to the broader body of stakeholder theory literature. (shrink)

Perhaps more than any philosophy written in the past few centuries, the work of Friedrich Nietzsche has given rise to controversy, misunderstanding, and dissent. Today Nietzsche is remembered as the revolutionary author of such polemical ideas as the death of God, the revaluation of values, the will to untruth, and the Übermensch. Yet is Nietzsche’s philosophy as atheistic, relativistic, nihilistic, and immoral as some commentators have claimed? Or ought we perhaps to give more credence to Nietzsche’s own assertion that one (...) writes books “precisely to conceal what one harbors” (BGE, 9, 289)? If “whatever is profound loves masks” (BGE, 2, 40) then might Nietzsche’s more daring claims be interpreted as clever masks behind which he conceals a deeper philosophy and on which he reveals a hidden truth? Is it not possible that the standard readings of Nietzsche are in fact misreadings—that his work invites misreading, that it is intentionally unclear, deceptive, disguised? The goal of this volume is to reread Nietzsche for all that he shows and all that he hides. It is to dig deeper into his work in order to challenge misreadings of old and invite misreadings anew—as, indeed, his work itself calls for and demands. (shrink)

According to a widely credited model in the business ethics literature, ethical decisions are a function of two kinds of factors, personal(individual) and situational, and these factors interact with each other. According to a contrary view of decision making that is widely held in some areas of business research, individuals’ decisions about ethical issues (and subsequent actions) are purely a function of their self-interest.The laboratory experiment reported in this paper provides a test of the person-situation interactionist model, using the general (...) theoretical and experimental framework used in the experimental economics literature. One individual and two situational factors relating to moral intensity were examined which may influence decisions to misrepresent information in the course of business activities.The individual and one situational variable were significantly related to participants’ actions. The interactions among individual andsituation variables were not individually significant, although the model including interactions had a much higher level of statistical significance. Gender was significant, both directly and in interaction with moral development, suggesting that it may be worthy of further examination. (shrink)

To our knowledge, this is one of the first studies to test different theoretical models of working memory in childhood based on a computerized assessment. We tested this across several countries: Argentina, Brazil, Canada, Italy, and UK. The present study addressed the wider macro-cultural context and how this impacts working memory. We used two economic indices to characterize the participating countries and ranked the countries based on the Global Index of Cognitive Skills and Educational Attainment. Children between 5 and 10 (...) years completed the same set of short-term and working memory tests. There were two main findings. First, there was a similar pattern in verbal working memory across countries, which suggests that this skill may be relatively consistent across different cultural groups. In contrast, the pattern for visuo-spatial working memory was different across countries, which may explained by cultural differences and educational rankings of the countries. The second main finding was that both a domain-general model and a domain-specific model provided a reasonably good fit with the data, there was the high relationship between the verbal and visuo-spatial working memory constructs across the countries in the latter model. Thus, it may be a more parsimonious choice to rely on a three-factor model. The data also suggest culture-similar patterns in a computerized assessment of working memory. (shrink)

Measuring outcomes using quantitative analytic methods is the hallmark of scientific research in healthcare. For clinical ethics support services (CESS), tangible outcome metrics are lacking and literature examining CESS quality is limited to evaluation of single cases or the influence on individual healthcare professional’s perceptions or behaviour. This represents an enormous barrier to implementing and evaluating ethics initiatives to improve quality. In this context, Kok _et al_ propose a theoretical framework for how moral case deliberation (MCD) can drive quality at (...) an organisational-level, termed _morisprudence_ 1. By offering mechanistic insights into how MCD can lead to organisational learning and quality improvement (QI), they provide a roadmap for actionable items to measure quality. As conceptualised, _morisprudence_ follows accumulation of organisational practical wisdom from a repertoire of ‘paradigmatic’ MCDs, aiding identification of patterns of morally important features. Here, there are parallels between healthcare professionals’ clinical judgement, where past experience... (shrink)

There are a number of problematic features within the current treatment of time in physical theories, including the “timelessness” of the Universe as encapsulated by the Wheeler–DeWitt equation. This paper considers one particular investigation into resolving this issue; a conditional probability interpretation that was first proposed by Page and Wooters. Those authors addressed the apparent timelessness by subdividing a faux Universe into two entangled parts, “the clock” and “the remainder of the Universe”, and then synchronizing the effective dynamics of the (...) two subsystems by way of conditional probabilities. The current treatment focuses on the possibility of using a realistic clock system; namely, a coherent-state description of a damped harmonic oscillator. This clock proves to be consistent with the conditional probability interpretation; in particular, a standard evolution operator is identified with the position of the clock playing the role of time for the rest of the Universe. Restrictions on the damping factor are determined and, perhaps contrary to expectations, the optimal choice of clock is not necessarily one of minimal damping. (shrink)

Tertullian is often portrayed as a prescient figure who accurately anticipated the Nicene consensus about the Trinity. But when he is examined against the background of his immediate predecessors, he falls into place as a typical second-century Logos theologian. He drew especially from Theophilus of Antioch, Justin Martyr, and Irenaeus of Lyons. At the same time, Tertullian did introduce some important innovations. His trinitarian language of ‘substance’ and ‘person’, rooted in Stoic metaphysics, offered the church a new way to be (...) monotheistic while retaining the full deity and consubstantiality of the Word. Tertullian also significantly developed the concept of a divine oikonomia, God’s plan to create and redeem the world. The Son and Spirit are emissaries of the Father’s will—not ontologically inferior to him, yet ranked lower in the way that the sent are always subordinate to the sender. For this reason, Tertullian denied that a Father/son relationship was eternal within the Trinity, seeing it rather as a new development emerging from God’s plan to make the world. Such temporal paternity and filiation distances Tertullian from the eventual Nicene consensus, which accepted instead the eternal generation theory of Origen. While Tertullian did propose some important terms that would gain traction among the Nicene fathers, he was also marked by a subordinationist tendency that had affinities with Arianism. Tertullian’s most accurate anticipation of Nicaea was his insistence on three co-eternal and consubstantial Persons. Historical theologians need to start admitting that Tertullian was a far cry from being fully Nicene. Rather, he offered a clever but still imperfect half-step toward what would become official orthodoxy.. (shrink)

In almost every clinical interaction, clinicians must navigate interpersonal challenges with near‐instantaneous responses to patients. Yet medical ethics has largely overlooked these small, interpersonal exchanges, instead focusing on “big” ethical problems, such as euthanasia, brain death, or genetic modification. In 1995, Paul Komesaroff proposed the concept of microethics as a nonprinciplist approach to ethics that focuses on “what happens in every interaction between every doctor and every patient.” We aim to develop a microethics framework to guide everyday clinical encounters, with (...) a special focus on communication with patients and family members. We will advance three core insights: First, communication is an ethical act in ways seldom considered. Second, microethics is an essential lens through which to view the ethics of communication. Third, virtue can bridge reflective and automatic processes. Our intuitionist framework for microethics is thus based on this understanding of the role of virtue, and we propose six virtues that contribute to the goal of healing communication. (shrink)

Obtaining informed consent, an ethical obligation of nurses and other health care providers, occurs routinely when patients make health care decisions. The values underlying informed consent (promotion of patients’ well-being and respect for their self-determination) are embedded in the dominant American culture. Nurses who apply the USA’s cultural values of informed consent when caring for patients who come from other cultures encounter some ethical dilemmas. This descriptive study, conducted with Latino, Chinese and Anglo-American cancer patients in a large, public, west-coast (...) clinic, describes constraints on the informed consent process in a multicultural setting, including language barriers, the clinical environment, control in decision making, and conflicting desired health outcomes for health care providers and patients, and suggests some implications for nursing practice.

In an item-method directed forgetting paradigm, participants were required to attend to one of two colored words presented on opposite sides of a central fixation stimulus; they were instructed to Remember or Forget the attended item. On a subsequent recognition test, the Attended words showed a typical directed forgetting effect with better recognition of Remember words than Forget words. Our interest was in the fate of the Unattended words. When the study display disappeared before the memory instruction, there was no (...) effect of that instruction on unattended words; when the study display remained visible during presentation of the memory instruction, there was a reverse directed forgetting effect with better recognition of unattended words from Forget trials than from Remember trials. Incidental encoding of task-irrelevant stimuli occurs following presentation of a Forget instruction – but only when those task-irrelevant stimuli are still visible in the external environment.

BackgroundAs a number of commentators have noted, SARS exposed the vulnerabilities of our health care systems and governance structures. Health care professionals (HCPs) and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCPs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were (...) exposed to serious risk of morbidity and mortality, as evidenced by the World Health Organization figures showing that approximately 30% of reported cases were among HCPs, some of whom died from the infection. Despite this challenge, professional codes of ethics are silent on the issue of duty to care during communicable disease outbreaks, thus providing no guidance on what is expected of HCPs or how they ought to approach their duty to care in the face of risk.DiscussionIn the aftermath of SARS and with the spectre of a pandemic avian influenza, it is imperative that we (re)consider the obligations of HCPs for patients with severe infectious diseases, particularly diseases that pose risks to those providing care. It is of pressing importance that organizations representing HCPs give clear indication of what standard of care is expected of their members in the event of a pandemic. In this paper, we address the issue of special obligations of HCPs during an infectious disease outbreak. We argue that there is a pressing need to clarify the rights and responsibilities of HCPs in the current context of pandemic flu preparedness, and that these rights and responsibilities ought to be codified in professional codes of ethics. Finally, we present a brief historical accounting of the treatment of the duty to care in professional health care codes of ethics.SummaryAn honest and critical examination of the role of HCPs during communicable disease outbreaks is needed in order to provide guidelines regarding professional rights and responsibilities, as well as ethical duties and obligations. With this paper, we hope to open the social dialogue and advance the public debate on this increasingly urgent issue. (shrink)

Issues of interest, identity and values intertwine in environmental conflicts, creating challenges that cannot generally be overcome using rationalities grounded in generalised argumentation and abstraction. To address the growing need to engage interests and identities along with plural values in the conservation of biodiversity and ecological systems, we introduce the concept of ‘appropriateness of actions’ and ground it in a relational understanding of environmental ethics. A determination of appropriateness for actions comes from combining outputs from value elicitation with those of (...) interest and identity negotiation in ways that are salient to specific people and their relationships to specific places. Drawing on the Blue Mountain Forest Partnership in the Pacific Northwest, we propose factors of success for supporting appropriate actions: 1) understanding context and identifying key stakeholders; 2) surfacing a diversity of interests and building system-level trust; 3) building empathy for different identities grounded in specific places; 4) eliciting diverse values and seeking to understand their links to worldviews and knowledge systems and; 5) seeking out appropriate actions.

For over a century, drawing from observation, at least at the introductory level, has been integral to many secondary and most post-secondary art school programs in Europe and North America. Its place in such programs is understood to develop an ability to see and interpret on a flat surface the real, three-dimensional world; this skill, in turn, provides support to related mental processes such as memory, visualization, and imagination. Where an artist looks when drawing from observation may not be arbitrary (...) and can be observed, quantified, and analyzed. Our interest in examining the first few minutes of the drawing process takes its lead from the novice’s question, "Where should I begin?" Attempting to understand these first few minutes led to a collaborative study between art educators and cognitive-perceptual psychologists: the former interested in implications for practical pedagogy, the latter in applying expertise in eye movement and scientific methodology in service of a specific real-world question. The stated purpose of the study notwithstanding, contrasting histories and practices in art and science provided contexts for discussion beyond the collection and interpretation of data. This article seeks to report upon and further that discussion. (shrink)

Electronic technologies, in general, and computer-oriented technologies specifically have had a tremendous impact on all aspects of business. One area of increased concern is the protection of intellectual properties -- notably copyrights -- within the boundaries of the broadly defined technology industry. While the ability to share copyrighted information has always existed at the most basic levels, the advent of the information age has allowed the sharing of this information to take place in potentially greater quantities and without a loss (...) of quality. As such, copying creates a major threat to industries dealing in the production and distribution of copyrightable creations. The focus of this paper is to better understand how the ethical judgments of employees regarding the opportunities to recreate copyrighted works via traditional and newer technologies impact assessments of copying behavior in the workplace.

Forenames serve as proxies for gender labels that activate gender stereotypes and gender socialization. Unlike rigid binary gender categories, they differ in the degree to which they are perceived as “masculine” or “feminine.” We examined the novel hypothesis that the ability of a forename to signal gender is associated with gender role behavior in women and men as part of a larger study evaluating forenames used in resume research. Compared to individuals endorsing a “gender-strong” forename, those perceiving their forename as (...) relatively “gender-weak” reported less gender-typical childhood social behavior and a weaker expression of gender-linked personality traits. Our findings suggest that forenames strengthen or weaken gender socialization, gender identification, and so contribute to the variable expression of gender role behavior within binary gender groups.

The N‐terminal domain of histone H4 has been implicated in various nuclear functions, including gene silencing and activation and replication‐linked chromatin assembly. Many of these have been identified by using H4 mutants in the yeast S. cerevisiae. In a recent paper, Megee et al.(1) use this approach to show that mutants in which all four N‐terminal H4 lysines are substituted with glutamines accumulate increased levels of DNA damage. A single lysine, but not an arginine, anywhere in the N‐terminal domain suppresses (...) this phenotype. It is suggested that histone H4 plays a role in maintaining genome integrity through the cell cycle, possibly by a mechanism involving lysine acetylation. (shrink)

Investigation of neural and cognitive processes underlying individual variation in moral preferences is underway, with notable similarities emerging between moral- and risk-based decision-making. Here we specifically assessed moral distributive justice preferences and non-moral financial gambling preferences in the same individuals, and report an association between these seemingly disparate forms of decision-making. Moreover, we find this association between distributive justice and risky decision-making exists primarily when the latter is assessed with the Iowa Gambling Task. These findings are consistent with neuroimaging studies (...) of brain function during moral and risky decision-making. This research also constitutes the first replication of a novel experimental measure of distributive justice decision-making, for which individual variation in performance was found. Further examination of decision-making processes across different contexts may lead to an improved understanding of the factors affecting moral behaviour. (shrink)

Language comprehension requires a simulation that uses neural systems involved in perception, action, and emotion. A review of recent literature as well as new experiments support five predictions derived from this framework. 1. Being in an emotional state congruent with sentence content facilitates sentence comprehension. 2. Because women are more reactive to sad events and men are more reactive to angry events, women understand sentences about sad events with greater facility than men, and men understand sentences about angry events with (...) greater facility than women. 3. Because it takes time to shift from one emotion to another, reading a sad sentence slows the reading of a happy sentence more for women than men, whereas reading an angry sentence slows the reading of a happy sentence more for men than for women. 4. Because sad states motivate affiliative actions and angry states motivate aggressive action, gender and emotional content of sentences interact with the response mode. 5. Because emotion simulation requires particular action systems, adapting those action systems will affect comprehension of sentences with emotional content congruent with the adapted action system. These results have implications for the study of language, emotion, and gender differences. (shrink)

Consumers are bombarded with labels and claims that are intended to address their concerns about how food products are produced, processed, and regulated. Among those are the natural or all-natural claims and the certified organic label. In this study, two focus groups were conducted to explore consumers’ attitudes toward all-natural and organic pork and to gather their reactions to the USDA organic standards for meat, and the policy for natural claims. Results indicated that participants had positive associations with the terms (...) “organic” and “all-natural” with exceptions regarding the trustworthiness of all-natural claims. Participants perceived the “no” labeling theme (no antibiotics, no hormones, no chemicals, etc.) often coupled with the all-natural label on pork products as identifying potential health and animal welfare risks. In response to the USDA standards and policies for labeling pork products as organic or all-natural, participants expressed confusion and had many unanswered questions. (shrink)

In this article, we conceptualize the under investigated and under theorized relationship between intimate partner violence (IPV) and business responsibility. As an urgent social issue, IPV—understood as abuse of power within the context of an intimate partner relationship, mainly perpetrated by men and involving a pattern of behavior—has been studied for decades in many disciplines. A less common yet vital research perspective is to examine IPV as it relates to the business and to ask how organizations should engage with IPV. (...) In response to this question, we contribute a framework drawing from two distinctions in the business responsibility scholarship: the assumed role of the organization (responsibility to the firm/market; responsibility to the broader socio-political-economic environment); and the second focused on the approach to conceptualizing ethics (justice/fairness; ethics of care). Thus, we explicate four approaches to business responsibility and IPV, which serve the purposes of mapping three selected contributions, identifying limitations of these approaches, and opening up future research opportunities.

Objectives: To test the range of beliefs regarding the ethics of testing, in resource poor settings, new therapies that are less efficacious but more affordable and feasible than the best current therapeutic standard. Design: Using a web-based survey, we presented a hypothetical scenario proposing to test a therapy for HIV disease ("therapeutic inoculation") known to be less efficacious than highly active antiretroviral therapy (HAART). Respondents evaluated various trial designs as ethical or unethical. Participants: 604 subscribers to two listservs for individuals (...) interested in international health research ethics. Main outcome measures: Proportion of respondents endorsing trials testing this "substandard" therapy, and proportion endorsing placebo-controlled trials. Results: There were 215 respondents from 47 countries. Forty-five percent of respondents were from low or middle income countries; 96% devoted at least some time to research activities; and 75% had "some" or "considerable" research experience in developing countries. Of respondents, 97% (95% CI 94.7 to 99.4) endorsed testing therapeutic inoculation, without HAART, in patients with HIV disease; 86% (95% CI 81.4% to 90.7%) endorsed testing against placebo. Sixty-eight percent explicitly endorsed principles where the standard of care for subjects in clinical trials is determined by local, not universal, standards. There were no differences in responses based on respondent education-level or the income-level of their country of citizenship. Conclusion: There was broad agreement that a therapy of potential local benefit may be tested, even when that therapy is known to be inferior to the standard of care in wealthy countries. Most agreed that a placebo control may be used in some circumstances. (shrink)

In an effort to further explore ostensible macroscopic psychokinesis (macro-PK) effects like those previously reported by Batcheldor (1966), Bourgeois (1994), Owen and Sparrow (1976), and Ullman (2001) in a sitter group setting, the first author designed and conducted a series of fifteen experimental sessions in which sitters claiming exceptional abilities attempted to generate a pseudo-spirit named "Daniel," to whom physical phenomena were attributed. To explore possible physical correlates of macro-PK, two approaches to measurement were utilized. In the first, sample data (...) from a local random number generator (RNG) continuously running as part of the Global Consciousness Project were extracted and examined for statistical deviations from randomness occurring in conjunction with the sitter group sessions. In the second, the Multi-Energy Sensor Array (MESA) was used to collect onsite environmental data during one of the sessions. While displays of ostensible macro-PK were observed during several of the sitter group sessions, the RNG data did not show a significant overall correlation with the sessions. The MESA data indicated notable drops in infrared and visual light, as well as changes in DC magnetic field strength, that are comparable to those observed in field studies of haunts. Keywords: sitter groups--macroscopic psychokinesis (macro-PK)--random number generator (RNG)--Multi-Energy Sensor Array (MESA). (shrink)

Histone deacetylase inhibitors (HDACi) are in clinical trials against a variety of cancers. Despite early successes, results against the more common solid tumors have been mixed. How is it that so many cancers, and most normal cells, tolerate the disruption caused by HDACi‐induced protein hyperacetylation? And why are a few cancers so sensitive? Here we discuss recent results showing that human cells mount a coordinated transcriptional response to HDACi that mitigates their toxic effects. We present a hypothetical signaling system that (...) could trigger and mediate this response. To account for the existence of such a response, we note that HDACi of various chemical types are made by a variety of organisms to kill or suppress competitors. We suggest that the resistance response in human cells is a necessary evolutionary consequence of exposure to environmental HDACi. We speculate that cancers sensitive to HDACi are those in which the resistance response has been compromised by mutation. Identifying such mutations will allow targeting of HDACi therapy to potentially susceptible cancers. (shrink)
