In the six remarkable elegidia transmitted in the Tibullan corpus as 3.13–18 we appear to possess the writings of an educated Roman woman of aristocratic family and high literary connections: a woman, moreover, who participates as an equal in one of the most distinguished artistic salons of the age, and composes poetry in an obstinately male genre on the subject of her own erotic experience, displaying a candour and the exercise of a sexual independence startingly at odds with the ideology (...) of her class. Such a figure is either, depending on one's viewpoint, too good to be true or too embarrassing to be tolerated. The case could easily be put that Sulpicia, more perhaps even than Sappho, has found her poems condemned by accident of gender to a century and a half of condescension, disregard, and wilful misconstruction to accommodate the inelastic sexual politics of elderly male philologists. Certainly even the most sympathetic of recent comment is prone to lapse into a form of critical language outlawed in Catullan scholarship thirty years ago. Yet feminist critics have been strangely cautious in their response. A scholar who rose swiftly to the defence of Erinna when that elusive poet's identity was impugned has notoriously written of Sulpicia: ‘She was not a brilliant artist: her poems are of interest only because the author is female.’ Five years late, Sulpicia has found a place in the major sourcebook on ancient women, but with the cycle of poems violently reordered after the judgment of a nineteenth-century critic, anxious to restore his poetess's chastity against the disconcerting frankness of the texts.

The role of followers in financial statement fraud has not been widely examined, even though these frauds typically involve collusion between followers and destructive leaders. In a study with 140 MBA students in the role of followers, we examined whether two follower personality traits were associated with behavioral intentions to comply with the demands of an unethical chief executive officer to be complicit in committing financial statement fraud. These personality traits are self-sacrificing self-enhancement, a form of maladaptive narcissism characterized by (...) seemingly altruistic behaviors that are actually intended to boost self-esteem and proactivity, a trait characterized by behaviors reflecting efforts to positively change one’s environment. As predicted, follower SSSE was positively associated with follower behavioral intentions to comply with CEO pressure to commit fraud, while follower proactivity was negatively associated with fraud compliance intentions. Also as predicted, follower SSSE interacted with follower proactivity, such that followers high in SSSE and high in proactivity reported greater intentions to resist pressure from the unethical CEO to commit fraud compared to low-SSSE followers. Implications for future research and corporate governance are discussed. (shrink)

According to Mednick’s (1962) theory of individual differences in creativity, creative individuals appear to have a richer and more flexible associative network than less creative individuals. Thus, creative individuals are characterized by “flat” (broader associations) instead of “steep” (few, common associations) associational hierarchies. To study these differences, we implement a novel computational approach to the study of semantic networks, through the analysis of free associations. The core notion of our method is that concepts in the network are related to each (...) other by their association correlations - overlap of similar associative responses (“association clouds”). We began by collecting a large sample of participants who underwent several creativity measurements and used a decision tree approach to divide the sample into low and high creative groups. Next, each group underwent a free association generation paradigm which allowed us to construct and analyze the semantic networks of both groups. Comparison of the semantic memory networks of persons with low creative ability and persons with high creative ability revealed differences between the two networks. The semantic memory network of persons with low creative ability seems to be more rigid, compared to the network of persons with high creative ability, in the sense that it is more spread out and breaks apart into more sub-parts. We discuss how our findings are in accord and extend Mednick’s (1962) theory and the feasibility of using network science paradigms to investigate high level cognition. (shrink)

In March 1912 A. N. Whitehead wrote a letter which sheds new and important light on his own view of his mathematical goals. In this article I publish the letter for the first time and relate its contents not only to his mathematical career but also to his scientific, philosophical and educational interests.

The aim of the paper is to prove the consistency of libertarianism. We examine the example of Jane, who deliberates at length over whether to vacation in Colorado (C) or Hawaii (H), weighing the costs and benefits, consulting travel brochures, etc. Underlying phenomenological deliberation is an indeterministic neural process in which nonactual motor neural states n(C) and n(H) corresponding to alternatives C and H remain physically possible up until the moment of decision. The neurophysiological probabilities pr(n(C)) and pr(n(H)) evolve continuously (...) according to the different weights Jane's judgement attaches to C and H at different times during the deliberation. The overall process is indeterministic, since Jane's exact judgemental weighting would vary slightly were the process to be repeated from the same initial conditions. The weighting is however rational, and entirely under Jane's control. This controlled, rational, indeterministic process shows that libertarianism is a consistent philosophical thesis. (shrink)

IntroductionLittle is known about risk factors for both Long COVID and somatic symptoms that develop in individuals without a history of COVID-19 in response to the pandemic. There is reason to assume an interplay between pathophysiological mechanisms and psychosocial factors in the etiology of symptom persistence.ObjectiveTherefore, this study investigates specific risk factors for somatic symptom deterioration in a cohort of German adults with and without prior SARS-CoV-2 infection.MethodsGerman healthcare professionals underwent SARS-CoV-2 IgG antibody testing and completed self-rating questionnaires at baseline (...) and 21 months later between April 2020 and February 2022. Differences in variables between the time points were analyzed and a regression analysis was performed to predict somatic symptom deterioration at follow-up.ResultsSeven hundred fifty-one adults completed both assessments. Until follow-up, n = 58 had contracted SARS-CoV-2 confirmed by serology. Between baseline and follow-up, signs of mental and physical strain increased significantly in the sample. Symptom expectations associated with COVID-19 and a self-reported history of COVID-19, but not serologically confirmed SARS-CoV-2 infection, significantly predicted somatic symptom deterioration at follow-up. A further predictor was baseline psychological symptom burden.ConclusionsThis study supports a disease-overarching biopsychosocial model for the development of burdensome somatic symptoms during the COVID-19 pandemic and supports research findings that symptom burden may be more related to the psychosocial effects of the pandemic than to infection itself. Future studies on Long COVID should include SARS-CoV-2 negative control groups and consider symptom burden prior to infection in order to avoid an overestimation of prevalence rates. (shrink)

Much attention has been directed to the philosophical implications of quantum field theory (QFT) in recent years; this paper attempts a survey in low-technical terms. First the relations of QFT to other kinds of theory, classical and quantum, particle and field, are discussed. Then various formulations of QFT are introduced, along with related interpretations. Finally a review is made of some of the most interesting foundational problems.

In an article entitled ‘Some Facts about our Oldest Latin Manuscripts,’ which appeared in this journal, the present writer put together a group of forty-seven MSS. which had this one feature in common, that each page or each column of a page they contained began with a large letter, regardless of whether that letter occurred in the middle of a sentence, or even in the middle of a word. It so happened that the list thus drawn up was composed almost (...) entirely of very ancient MSS.; indeed, it contained a very large proportion of the oldest MSS. extant. In the circumstances it seemed useful to note down the behaviour of these MSS. with respect to four other features—namely, the manner of indicating the omission of m and n at the end of lines, the use of running titles in the top margin, the size and arrangement of the written space, and the manner of signing quires.

We show that every countable ideal of degrees that are low for isomorphism is contained in a principal ideal of degrees that are low for isomorphism by adapting an exact pair construction. We further show that within the hyperimmune free degrees, lowness for isomorphism is entirely independent of computable traceability.

This paper discusses the practice of cost-benefit analyses of transportation infrastructure investment projects from the meta-theoretical perspective of critical realism. Such analyses are based on a number of untenable ontological assumptions about social value, human nature and the natural environment. In addition, main input data are based on transport modelling analyses based on a misleading `local ontology' among the model makers. The ontological misconceptions translate into erroneous epistemological assumptions about the possibility of precise predictions and the validity of willingness-to-pay investigations. (...) Accepting the ontological and epistemological assumptions of cost-benefit analysis involves an implicit acceptance of the ethical and political values favoured by these assumptions. Cost-benefit analyses of transportation investment projects tend to neglect long-term environmental consequences and needs among population groups with a low ability to pay. Instead of cost-benefit analyses, impact analyses evaluating the likely effects of project alternatives against a wide range of societal goals is recommended, with quantification and economic valorisation only for impact categories where this can be done in an ontologically and epistemologically defensible way.

The purpose of this article is to deliberate the moral and legal dilemma entailed in the weapon of the labour strike as a pressure tactic on the Israeli Finance Ministry regarding job slots, budgets and, in effect, violating the collective agreement signed by the nurses and impairing patients’ treatment, as opposed to refraining from striking and suffering the heavy burden of work, the lack of trained personnel, low wages, and the inability to give patients proper, high quality treatment.

We present a dynamic programming model which is used to investigate hypothermia as an adaptive response by small passerine birds in winter. The model predicts that there is a threshold function of reserves during the night, below which it is optimal to enter hypothermia, and above which it is optimal to rest. This threshold function decreases during the night, with a particularly sharp drop at the end of the night, representing the time and energy costs associated with returning to normal (...) body temperature. The results of the model emphasise the trade-off between energy and predation, not just between foraging options, but also between foraging during the day and entering hypothermia at night. The value of being able to use hypothermia represents not just energy savings, but also reduced predation risk due to changes in the optimal foraging strategy. Conditions which give a high value of hypothermia are short photoperiod, variable food supply, low temperatures, poor and scarce food supplies. (shrink)

The evidence of ancient books points to the surprising conclusion that in texts of drama or prose dialogue changes of speaker were not usually marked by the name of the new speaker.

As far as prose dialogues are concerned confirmation can be found in an unexpected source: the prologue to the dialogue Eranistes by the fifth-century church father Theodoret. (shrink)

The goal of the present study was to elucidate what influences medical students’ attitudes and interests in medical ethics. At the end of their first, fifth and last terms, 409 medical students from all six medical schools in Sweden participated in an attitude survey. The questions focused on the students’ experience of good and poor role models, attitudes towards medical ethics in general and perceived effects of the teaching of medical ethics. Despite a low response rate at some schools, this (...) study indicates that increased interest in medical ethics was related to encountering good physician role models, and decreased interest, to encountering poor role models. Physicians involved in the education of medical students seem to teach medical ethics as role models even when ethics is not on the schedule. The low response rate prevents us from drawing definite conclusions, but the results could be used as hypotheses to be further scrutinised. (shrink)

Wal-Mart received widespread praise for its response to Hurricane Katrina when it hit the Louisiana coast in August 2005 and low prices at the world’s largest retailer are estimated to save consumers billions of dollars a year. Nonetheless, it was coming under increasing criticism for corebusiness practices, ranging from detrimental effects on communities when Wal-Mart stores are established, to abusive labour practices, to alleged sourcing from sweatshops. This case looks at the benefits and the potentially harmful consequences of the Wal-Mart (...) business model. The focus is on supply chain issues and, more specifically, a lawsuit brought by the International Labor Rights Fund (ILRF) charging that Wal-Mart failed to meet contractual obligations specified in its Standards for Suppliers Agreement. However, the retailer must respond to a range of criticisms that chief executive Lee Scott recognizes are harming its reputation. Scott asks, in reference to Wal-Mart’s response to Katrina, “what would it take for Wal-Mart to be that company, at our best, all the time?” More fundamentally, the case asks, how sustainable is Wal-Mart’s business model?

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

All recent memory theories of hippocampal function have incorporated the idea that the hippocampus is required to process items only of some qualitatively specifiahle kind, and is not required to process items of some complementary set. In contrast, it is now proposed that the hippocampus is needed to process stimuli of all kinds, but only when there is a need to associate those stimuli with other events that are temporally discontiguous. In order to form or use temporally discontiguous associations, it (...) is essential to maintain some memory of the first component until the second component has occurred. When the temporal gap to he spanned is small, and the number of items to be temporarily retained is low, a limited-capacity, short-term store is sufficient to allow associations to be formed. Such a store is presumed to operate in parallel with the hippocampus in normal animals. Hippocampal damage disrupts a much higher-capacity store that has a slower decay rate, and so leaves animals with only a very limited ability to form temporally discontiguous associations. Hippocampal damage, however, is not held to affect the long-term storage of associations of any kind, if they can be formed. Analyses of both new and existing data are presented to show that by classifying tasks in terms of the need to use a temporary memory store to retain temporally discontiguous information one can cut right across existing classifications as well as achieve a better fit to the data. The hippocampus thus seems best described as a high-capacity, intermediate-term memory store. (shrink)

Leaders who express an ethical identity are proposed to affect followers’ attitudes and work behaviors. In two multi-source studies, we first test a model suggesting that work engagement acts as a mediator in the relationships between ethical leadership and employee initiative (a form of organizational citizenship behavior) as well as counterproductive work behavior. Next, we focus on whether ethical leadership always forms an authentic expression of an ethical identity, thus in the second study, we add leader Machiavellianism to the model. (...) For Machiavellian leaders, the publicly expressed identity of ethical leadership is inconsistent with the privately held unethical Machiavellian norms. Literature on surface acting suggests people can at least to some extent pick up on such inauthentic displays, making the effects less strong. We thus argue that the positive effects of ethical leader behavior are likely to be suppressed when leaders are highly Machiavellian. Support for this moderated mediation model was found: The effects of ethical leader behavior on engagement are less strong when ethical leaders are high as opposed to low on Machiavellianism.

Background: Discussing treatment risks has become increasingly important in medical communication. Still, despite regulations, physicians must decide how much and what kind of information to present. Objective: To investigate patients’ preference for information about a small risk of a complication of colonoscopy, and whether medical and personal factors contribute to such preference. To propose a disclosure policy related to our results. Design: Vignettes study. Setting: Department of Gastroenterology, Academic Medical Centre, the Netherlands. Patients: 810 consecutive colonoscopy patients. Intervention: A home-sent (...) questionnaire containing three vignettes. Vignettes varied in the indication for colonoscopy, complication severity and level of risk. Patients were invited to indicate their wish to be informed and the importance of such information. In addition, sociodemograhic, illness-related and psychological characteristics were assessed. Main outcome measurements: Wish to be informed and importance of information. Results: Of 810 questionnaires, 68% were returned. Patients generally wished to be informed about low-risk complications, regardless of the indication for colonoscopy or the severity of the complication. The level of risk did matter, though (OR = 2.48, SE = 0.28, p = 0.001). The information was considered less important if done for population screening purposes or diagnosis of colon cancer, if the complication was less severe (bleeding) and if the risk was smaller (0.01% and 0.1%). Patients’ information preference was also related to age, mood and coping style. Limitations: Difficulty of vignettes. Conclusions: Patients generally wish to be informed about all possible risks. However, this might become uninformative. A stepwise approach is suggested. (shrink)

The present study investigated children’s understanding development of multiple graphics, here paired conventions commonly used in primary school textbooks. Paired graphics depicting everyday objects familiar to the children were used as the basis for an analogy task that tested their comprehension of five graphics conventions. This task required participants to compare pictures in a base pair in order to complete a target pair by choosing the correct picture from five alternative possibilities. Four groups of children aged 5, 6, 8 and (...) 10 years old respectively (total N = 105), completed 45 analogy task items built around nine conceptual domains. Results showed mainly an overall increase of comprehension performance with age for all the tested conventions. There were also differences between the five conventions and an interaction between age and convention type. Further, children's explanation of the conventions (justification of the choices in the analogy task) were also analyzed. This investigation showed the analogy task answers were a more reliable measure of the "actual" level of understanding of the conventions than the justification themselves. The findings show that younger students tried to actively compare the pictures of the pairs and to search for a relevant meaning of the pairs, however, the youngest children have a limited capacity to interpret paired graphic conventions and our results suggests that this aspect of graphic conventions develops slowly but effectively over the course of children’s schooling. Because "graphicacy" knowledge and skills are not typically taught in primary school classrooms (in contrast with literacy and numeracy), its development is likely acquired incidentally with increasing exposure to varied paired graphics during primary school education. Given the high reliance of today’s educational resources on graphics-based explanations, the results from this study may signal a need for (i) for more attention to learning graphics conventions (and more generally to graphics explanations) from teachers in primary school and (ii) for a better design of the graphics with their contextual accompanying texts and captions, from designers.

The experienced qualities of memories of factual and fictional events have been little researched previously. The few studies that exist find no or few differences. However, one reason to expect differences in memory qualities is that processing of fact and fiction seem to involve activation of different brain areas. The present study expands earlier research by including a wider range of memory qualities, using positive and negative events, and three time-points: immediately after, after a ten-minute delay and after a five-week (...) delay. Participants (N = 52) read four short stories in English, labelled either fact or fiction, and rated memory qualities on 7-point scales. Results show no differences; however, an interaction was found between fictionality and story emotional valence, in that memories of negative fictional stories are rated as more clear. The higher clarity can be explained by previous findings that negative events from stories are in general remembered in more detail, in combination with the idea that fiction entails simulation to a higher degree than fact. The conclusion is that although a difference in memory qualities between fact and fiction was found in one case, memory qualities seem not to play an operative role when the memory system distinguishes fact from fiction.

This paper examines in some detail the chief reasons for the low ethical standards in public administration today. References have been made to the concept of dharma and the principles for ethics in public adminis tration as reflected in our tradition in the Vedanta, Upanishads, Manu and the Bhagwad Gita. Several radi cal, legal and systemic remedies are suggested and defended at length. The leitmotif of all this is an earnest call to return to and practise the ancient principles of (...) dharma to manage the polity on the basis of enduring verities. The suggestions offered by the author are all anchored in such permanent principles. (shrink)

The present study investigates the relations between L2-English proficiency and L1-Turkish lexical property evaluations. We asked whether L2 proficiency affects lexical properties, including imageability and concreteness ratings of 600 Turkish words selected from the Word Frequency Dictionary of Written Turkish. Seventy-two participants provided ratings of concreteness and imageability for 600 words on a 7-point scale. In order to assess their L2 proficiency, we administered Peabody Picture Vocabulary Test-IV. We divided categories into two subcategories as high and low for the frequency, (...) concreteness, imageability, and age of acquisition. The relationship between these subcategories and imageability-concreteness was examined by mixed effects linear regression analyses. We found that L2 proficiency and imageability ratings were positively correlated and specifically, this positive association was evident for low-frequency words and later acquired words. Results are in line with the interaction of bilingual representation under the dual-coding theory which suggests that bilinguals develop an interconnected imaginal representation for two languages as opposed to separate verbal representations. As L2 proficiency increased, the imageability also increased. These findings have implications for literature investigating the relationship between L2 proficiency and linguistic outcomes. Additionally, findings point to the importance of considering the L2 proficiency of participants when lexical tasks that involve cue words or word lists are used. (shrink)

In order to prepare bioethics and clinical ethics courses for clinicians in Turkey, we needed to know the attitudes of physicians when placed in ethically difficult care situations. We presented four cases to 207 physicians who are members of the Physicians’ Association in Kocaeli, Turkey. Depending on the decisions they made in each case, we determined whether they were aware of the ethical aspects of the cases and the principles they chose as a basis for their decisions. We aimed to (...) gain information about their ethical tendencies and moral sensitivity. A small number of physicians stated that they would ‘show respect for a patient’s living will’ in the first case, but more stated that they would ‘let the patient refuse the treatment’ in the second. In the third case, where medical confidentiality was the significant ethical issue, most of the physicians said that they would act in order to maintain confidentiality. For the last case, more than half the physicians chose to ‘tell the truth’ to the patient. The paternalism shown in the doctors’ decisions on the first two cases was no longer observed in those made for the last two cases. We concluded that the physicians who participated in our study have low sensitivity to living wills (or advance directives) and patients refusing treatment. However, when issues of medical confidentiality and truth-telling are concerned, they take care to protect the autonomy of the individual and are relatively more aware of the ethical aspects of these cases.
