BackgroundMulti-centre studies generally cost more than single-centre studies because of larger sample sizes and the need for multiple ethical approvals. Multi-centre studies include clinical trials, clinical quality registries, observational studies and implementation studies. We examined the costs of two large Australian multi-centre studies in obtaining ethical and site-specific approvals.MethodsWe collected data on staff time spent on approvals and expressed the overall cost as a percent of the total budget.ResultsThe total costs of gaining approval were 38 % of the budget for (...) a study of 50 centres (mean cost AUD $6960 per site) and 2 % for a study of 11 centres (mean cost AUD $2300 per site). Seventy-five and 90 % of time was spent on repeated tasks, respectively, and many time-consuming tasks, such as reformatting documents, did nothing to improve the study design or participant safety.ConclusionsImprovements have been made to the ethical approval application system, but more gains could be made without increasing risks of harm to research participants. We propose that ethical review bodies and individual sites publish statistics on how long they take to process approvals which could then be nationally benchmarked. (shrink)

Progress towards Universal Health Coverage (UHC) requires making difficult trade-offs. In this journal, Dr. Margaret Chan, the WHO Director-General, has endorsed the principles for making such decisions put forward by the WHO Consultative Group on Equity and UHC. These principles include maximizing population health, priority for the worse off, and shielding people from health-related financial risks. But how should one apply these principles in particular cases and how should one adjudicate between them when their demands conflict? This paper by some (...) members of the Consultative Group and a diverse group of health policy professionals addresses these questions. It considers three stylized versions of actual policy dilemmas. Each of these cases pertains to one of the three principal dimensions of progress towards UHC: which services to cover first, which populations to prioritize for coverage, and how to move from out-of-pocket expenditures to pre-payment with pooling of funds. Our cases are simplified to highlight common trade-offs. While we make specific recommendations, our primary aim is to demonstrate both the form and substance of the reasoning involved in striking a fair balance between competing interests on the road to UHC.

Not limited to merely mathematics, probability has a rich and controversial philosophical aspect. _A Philosophical Introduction to Probability_ showcases lesser-known philosophical notions of probability and explores the debate over their interpretations. Galavotti traces the history of probability and its mathematical properties and then discusses various philosophical positions on probability, from the Pierre Simon de Laplace's “classical” interpretation of probability to the logical interpretation proposed by John Maynard Keynes. This book is a valuable resource for students in philosophy and mathematics and (...) all readers interested in notions of probability. (shrink)

One of the first to criticize the verifiability theory of meaning embraced by logical empiricists, Reichenbach ties the significance of scientific statements to their predictive character, which offers the condition for their testability. While identifying prediction as the task of scientific knowledge, Reichenbach assigns induction a pivotal role, and regards the theory of knowledge as a theory of prediction based on induction. Reichenbach’s inductivism is grounded on the frequency notion of probability, of which he prompts a more flexible version than (...) that of Richard von Mises. Unlike von Mises, Reichenbach attempts to account for single case probabilities, and entertains a restricted notion of randomness, more suitable for practical purposes. Moreover, Reichenbach developed a theory of induction, absent from von Mises’s perspective, and argued for the justification of induction. This article outlines the main traits of Reichenbach’s inductivism, with special reference to his book Experience and prediction. (shrink)

Investigations into the neurobiology of moral cognition are often done by examining clinical populations characterized by diminished moral emotions and a proclivity toward immoral behavior. Psychopathy is the most common disorder studied for this purpose. Although cocaine abuse is highly co-morbid with psychopathy and cocaine-dependent individuals exhibit many of the same abnormalities in socio-affective processing as psychopaths, this population has received relatively little attention in moral psychology. To address this issue, the authors used functional magnetic resonance imaging (fMRI) to record (...) hemodynamic activity in 306 incarcerated male adults, stratified into regular cocaine users (n = 87) and a matched sample of non-cocaine users (n = 87), while viewing pictures that did or did not depict immoral actions and determining whether each depicted scenario occurred indoors or outdoors. Consistent with expectations, cocaine users showed abnormal neural activity in several frontostriatial regions during implicit moral picture processing compared to their non-cocaine using peers. This included reduced moral/non-moral picture discrimination in the vACC, vmPFC, lOFC, and left vSTR. Additionally, psychopathy was negatively correlated with activity in an overlapping region of the ACC and right lateralized vSTR. These results suggest that regular cocaine abuse may lead to affective deficits which can impact relatively high-level processes like moral cognition. Moreover, they add to a growing body of research suggesting an important role for the mesocorticolimbic dopamine pathway in socio-affective processing. (shrink)

Using a multimethod approach, this article examines the link between class and masculinities by comparing the way two groups—professional men and working-class men —practice fatherhood. First, the authors show that these two groups practice different types of masculinity as they engage in different kinds of fatherhood. Physicians emphasize “public fatherhood,” which entails attendance at public events but little involvement in the daily care of their children. In contrast, EMTs are not only involved in their children's public events but also emphasize (...) “private fatherhood,” which entails involvement in their daily care. Second, the authors suggest that these differing types of involvement can be explained by the contrasting employment conditions of each group as well the gender order of their families, especially the divergent labor market positions of spouses and the division of parenting. The authors conclude by arguing that these working-class fathers are “undoing gender” while professional fathers reproduce the conventional gender order. (shrink)

Probability is the subject of considerable attention by Nagel, who devoted to it several writings. In the 1930s, Nagel put forward his “truth frequency” view of probability intended as a variant of the frequency theory minus the flaws to which this latter was susceptible. This paper illustrates how, according to Nagel, the issue of the meaning of probability should be addressed; Nagel’s criticism of the major interpretations of probability advanced in the literature, and the main traits of his “truth-frequency” theory.

Pragmatism, taken not just as a philosophical movement but as a way of addressing problems, strongly influenced the debate on the foundations of probability during the first half of the twentieth century. Upholders of different interpretations of probability such as Hans Reichenbach, Ernest Nagel, Rudolf Carnap, Frank Ramsey, and Bruno de Finetti, acknowledged their debt towards pragmatist philosophers, including Charles Sanders Peirce, William James, Clarence Irving Lewis, William Dewey and Giovanni Vailati. In addition, scientist-philosophers like Ernst Mach, Ludwig Boltzmann, Henri (...) Poincaré, Pierre Duhem, and Karl Pearson, who heralded a conception of science and knowledge at large that was close to pragmatism, were very influential in that debate. Among the main interpretations of probability – frequentism, propensionism, logicism and subjectivism -, the latter is no doubt the closest to the pragmatist outlook. This paper concentrates on three representatives of the subjective theory, namely Frank Ramsey, Bruno de Finetti and Émile Borel. (shrink)

This contribution claims that the two fundamental notions of causation at work in the health sciences are manipulative and mechanistic, and investigates what kinds of evidence matter for the assessment of causal relations. This article is a development of our 2007 article, ‘Plurality of Causality’, where we argue for a pluralistic account of causation with an eye to econometrics and a single medical example. The present contribution has a wider focus, and considers the notion of evidence within a whole range (...) of disciplines belonging to the health sciences. Section 1 addresses the relations between kinds of evidence and causal accounts, and it is shown how different notions of causation can be employed in various medical cases. Section 2 calls attention to issues crucial for any adequate epistemological theory of causation, such as the distinctions between types and tokens, observational and experimental regimes, explanation and prediction. Lastly, the notion of context is articulated, highlighted in its role in the assessment of causal links. All these issues are tackled in the framework of what we label a ‘bottom–up’ epistemology.

Harold Jeffreys' ideas on the interpretation of probability and epistemology are reviewed. It is argued that with regard to the interpretation of probability, Jeffreys embraces a version of logicism that shares some features of the subjectivism of Ramsey and de Finetti. Jeffreys also developed a probabilistic epistemology, characterized by a pragmatical and constructivist attitude towards notions such as ‘objectivity’, ‘reality’ and ‘causality’. 1 Introductory remarks 2 The interpretation of probability 3 Jeffreys' probabilistic epistemology.

Background: The phenomenon of forceful physical restraint in pediatric care is an ethical issue because it confronts professionals with the dilemma of using force for the child’s best interest. This is a paradox. The perspective of healthcare professional working in pediatric wards needs further in-depth investigations. Purpose: To explore the perspectives and behaviors of healthcare professionals toward forceful physical restraint in pediatric care. Methods: This qualitative ethnographic study used focus groups with purposeful sampling. Thirty volunteer healthcare professionals (nurses, hospital aids, (...) physiotherapists, and health educators) were recruited in five pediatric facilities in four hospitals around Paris, France, from March to June 2013. The data were processed using NVIVO software (QSR International Ltd. 1999–2013). The data analysis followed a qualitative methodological process. Ethical Considerations: The research was conducted in compliance with the Declaration of Helsinki. Written informed consent was collected systematically from participants. Findings: This study provides elements to help understand why restraint remains common despite its contradiction with the duty to protect the child and the child’s rights. All participants considered the use of forceful physical restraint to be a frequent difficulty in pediatrics. Greater interest in the child’s health was systematically used to justify the use of force, with little consideration for contradictory or ethical aspects. Raising the issue of forceful restraint always triggered discomfort, unease and an outpour of emotions among healthcare professionals. The findings have highlighted a form of hierarchy of duties that give priority to the execution of the technical procedure and legitimize the use of restraint. Professionals seemed to temporarily suspend their ability to empathize in order to apply restraint to carry out a technical procedure. This observation has allowed us to suggest the concept of “transient empathic blindness.” Conclusion: Using physical restraint during pediatric care was considered a common problem by participants. This practice must be questioned, and professionals must have access to training to find alternatives to strong restraint. Conceptualizing this phenomenon with the concept of “transient empathic blindness” could help professionals understand what happens in their minds when using forceful restraint. (shrink)

This study aimed to explore the influence of the visuospatial active working memory sub-components on early math skills in young children, followed longitudinally along the first two years of primary school. We administered tests investigating visual active working memory (jigsaw puzzle), spatial active working memory (backward Corsi), and math tasks to 43 children at the beginning of first grade (T1), at the end of first grade (T2), and at the end of second grade (T3). Math tasks were select according to (...) the children’s age and their levels of formal education: the “Battery for the evaluation of numerical intelligence from 4 to 6 years of age” (BIN 4–6) at T1 to test early numerical competence and the “Test for the evaluation of calculating and problem-solving abilities” (AC-MT 6–11) to test math skills at T2 and T3. Three regression models, in which the predictors were identified through a forward selection based on the use of the Bayesian information criterion (BIC) index, were performed to study the relationship between visual and spatial working memory and math ability at the three points in time. The results show that spatial working memory influences early numerical performance at T1, while early numerical performance is the unique predic-tor of math performance at T2. At the end of the second grade, the regression model reveals a relationship between math performance and both visual and spatial working memory and the attenuation of the importance of domain-specific predictors. The study depicts the dif-ferent implications of visual and spatial working memory predictors over the children’s de-velopment periods and brings additional evidence to the debate on the relationship between visuospatial working memory and math ability in young children.

Background The legitimacy of conscientious objection to abortion continues to fuel heated debate in Italy. In two recent decisions, the European Committee for Social Rights underlined that conscientious objection places safe, legal, and accessible care and services out of reach for most Italian women and that the measures that Italy has adopted to guarantee free access to abortion services are inadequate. Nevertheless, the Ministry of Health states that current Italian legislation, if appropriately applied, accommodates both the right to conscientious objection (...) and the right to voluntary abortion. Main body One empirical argument used to demonstrate that conscientious objection does not create barriers to abortion is the “no correlation” argument, which the Italian Committee for Bioethics employed to demonstrate that no association exists between conscientious objection and waiting times for voluntary abortion in Italy and to support the weak form of conventional comprise adopted by the Italian legislation to balance the conflict between women’ autonomy and healthcare professionals’ moral integrity. Conversely, we showed how the “no correlation” argument fails to demonstrate the absence of a relationship between the number of conscientious objectors and waiting times for voluntary abortion, and that the limitations of the “no correlation” argument itself demonstrate how it is still difficult to describe the real effect of conscientious objection on the access to abortion services and to evaluate the suitability of conventional compromise to effectively balance conflicting moral principles. Conclusion Further studies are needed to better describe the relationship between conscientious objection and waiting times for voluntary abortion. If new evidence would show that the increasing proportion of objectors does undermine the efficacy of the Italian law and the right of a woman to freely obtain a voluntary abortion, new ways will need to be found to address the conflict between moral principles and restrict the protection accorded to the principle of moral integrity. This would inevitably imply the need to constrain and to redefine the terms and conditions for claiming conscientious objection. (shrink)

The literature presents a broad approach to Corporate Social Responsibility, which aggregates a diversity of issues, such as the environment, labor conditions, and human rights. We addressed the impact of increasing CSR demands during the internationalization of emerging market multinationals on one particular subject, animal welfare. This subject raises important ethical concerns, especially as we understand that animals are sentient beings. Through content analysis of annual reports, we tracked the evolution of AW-CSR activities throughout the internationalization of two large Brazilian (...) meat-processing multinationals as they accessed markets with complex AW regulations. We also synthetized findings on broiler chicken on-farm AW research in Brazil and conducted interviews to gauge the impact of CSR standards on animals. Our findings show that, although EMNs that enter developed markets engage with various standards, the impacts of standard enforcement on actual welfare are not straightforward and call for broader AW and animal ethics developments. Uneven results among AW criteria indicate that some aspects are prioritized over others. Furthermore, some actions of actors such as EMNs and low-tier suppliers seem to counterbalance the expected impact of normative pressures to change the lives of animals for the better. We conclude that AW standards may improve AW in emerging markets; but these standards do not appear to be sufficiently stringent, and require improvements to have a more significant positive impact. A major signal emerging from this research is the fundamental need to broaden the animal ethics debate regarding the use of animals to produce meat. (shrink)

We argue that there are names with de se contents and that they are theoretically fruitful. De se names serve to challenge intuitive and otherwise plausible orthodoxies such as Stalnaker's view of communication and Bayesian views of belief update. These implications are also significant for those already sympathetic to the irreducibility of de se content.

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

The market-based innovation known as assisted living (AL) has changed the landscape of long-term care in the US. Using Edgar Schein’s three-level conceptual framework of organizational culture and data from a two-year qualitative study of five AL facilities located in suburban Philadelphia, we argue that misalignments among publicly stated values, material artifacts, and underlying assumptions can create a climate that fosters ethical tension. Drawing on forty-five in-depth interviews with staff at all levels, we derive five operational assumptions that guide behavior (...) in the facilities included in our study, and we describe how facility artifacts and espoused values give rise to ethical tensions and, at times, ethical violations. The findings highlight the imperative for providers and managers in all industries to look beyond the façade of artifacts and espoused values to underlying assumptions, and to recognize that these three levels must be aligned in order to create and sustain a culture in which ethics is a visible and enduring element and where ethical conduct is encouraged on an everyday basis.

The aim of this paper is to examine the philosophical sources of some of the criticisms made in the second half of the 20th century to the practices and the main assumptions of historiography. In particular, the influence of the writings by Nietzsche dedicated to European Historicism on the renewed concept of history which is imposed in the twentieth century from the thought of Heidegger and Foucault. The divergent concepts of historical time and existential temporality, as well as those of (...) narrative unity and continuity of historical events, are the concepts that mainly fall under the critical scrutiny of these thinkers. Archaeological investigations that Foucault devotes to institutions and procedures of the European past are mentioned as examples of the critical review of traditional historiography. (shrink)

Alzheimer's disease (AD) is the most common cause of dementia, and there is currently no cure. The “β‐amyloid cascade hypothesis” of AD is the basis of current understanding of AD pathogenesis and drug discovery. However, no AD models have fully validated this hypothesis. We recently developed a human stem cell culture model of AD by cultivating genetically modified human neural stem cells in a three‐dimensional (3D) cell culture system. These cells were able to recapitulate key events of AD pathology including (...) β‐amyloid plaques and neurofibrillary tangles. In this review, we will discuss the progress and current limitations of AD mouse models and human stem cell models as well as explore the breakthroughs of 3D cell culture systems. We will also share our perspective on the potential of dish models of neurodegenerative diseases for studying pathogenic cascades and therapeutic drug discovery. (shrink)

Robots are versatile devices that are promising tools for supporting teaching and learning in the classroom or at home. In fact, robots can be engaging and motivating, especially for young children. This paper presents an experimental study with 81 kindergarten children on memorizations of two tales narrated by a humanoid robot. The variables of the study are the content of the tales (knowledge or emotional) and the different social behaviour of the narrators: static human, static robot, expressive human, and expressive (...) robot. Results suggest a positive effect of the expressive behaviour in robot storytelling, whose effectiveness is comparable to a human with the same behaviour and better when compared with a static inexpressive human. Higher efficacy is achieved by the robot in the tale with knowledge content, while the limited capability to express emotions made the robot less effective in the tale with emotional content.

Secondly, the manipulative view of causality is sketched and the possibility of its integration with Salmon's theory is considered for the purpose of coping with some of the problems raised by (...) its critics.

Slaughter sets the debate about what is acceptable to do to animals at an extremely low bar. Recently, there has been considerable investment in developing cell-based meat, an alternative meat production process that does not require the raising and slaughtering of animals, instead using muscle cells cultivated in a bioreactor. We discuss the animal ethics impacts of cell-based and plant-based meat on human-animal interactions from animal welfare and rights perspectives, focusing on industrial meat production scenarios. Our hypothesis is that the (...) insertion of cell-based meat in the global meat market may alleviate farm animal suffering and potentially restore resources for wild fauna. We employed a conservative estimation of the cell-based meat contribution to the global meat market in the year 2040 to analyze the consequences for human-animal relationships for both wild animals and farmed domesticated animals. We discuss possible effects of an animal cell domestication process, previously described as the second domestication, on human-animal relationships. We consider its potential to reduce the impact of human demographic changes and land use on animal life, in particular whether there would be increased biomass availability and free land for wild animals. We anticipate a major reduction in animal suffering due to the decrease in the number of individual animals involved in food production, which justifies the adoption of cell-based meat from a utilitarian perspective. For the conventional animal food production that remains, further consideration is needed to understand which systems, either high or low welfare, will be retained and the impact of the innovation on the average farm animal welfare. Additionally, it seems likely that there will be less acceptance of the necessity of animal suffering in farming systems when meat production is uncoupled from animal raising and slaughter, supported by a deontological perspective of animal ethics. Consequent to this is anticipated the mitigation of relevant barriers to animal protection and to the recognition of animals as subjects by legislation. Thus, the development of the alternative meats may be related to a significant change in our relationship with non-human animals, with greater benefits than the prima facie effects on farm animals.

This volume broadens our concept of reasoning and rationality to allow for a more pluralistic and situational view of human thinking as a practical activity. Drawing on contributors across disciplines including philosophy, economics, psychology, statistics, computer science, engineering, and physics, _Reasoning, Rationality, and Probability_ argues that the search for strong theories should leave room for the construction of context-sensitive conceptual tools. Both science and everyday life, the authors argue, are too complex and multifaceted to be forced into ready-made schemata.

Probability as understood today, namely as a quantitative notion expressible by means of a function ranging in the interval between 0–1, took shape in the mid-17th century, and presents both a mathematical and a philosophical aspect. Of these two sides, the second is by far the most controversial, and fuels a heated debate, still ongoing. After a short historical sketch of the birth and developments of probability, its major interpretations are outlined, by referring to the work of their most prominent (...) representatives. The final section addresses the question of whether any of such interpretations can presently be considered predominant, which is answered in the negative. (shrink)

This article considers the multifaceted concept of ethics and how, despite being a familiar notion within education, it is still much contested within literature and professional practice. Drawing on postmodern, feminist and political literature, the authors explore conceptualisations of ethics and ethicality in relation to ethical identity, professionalism and practice. Applying philosophical and metaphorical tools, such as the rhizome and nomad, the authors suggest there is the potential to accommodate the multiple and often divergent facets of ethics, thereby engaging with (...) different ethical possibilities. It is argued that the propensity for reducing ethics to merely procedural protocols and guidelines marginalises the richness of ethics and, all too frequently, leaves practitioners ill-equipped to navigate the reality of day-to-day ethics.The article is positioned within the field of early years practice and training EY practitioners. This reflects the authors’ own specialism but also celebrates the propensity of the EY practitioner to reflect upon, question and challenge their own practice and ethical identities. This does not reduce the applicability of the subject matter which is relevant to educators of children of any age. The term ‘practitioner’ is used throughout to refer to any adult working with children in an educative role, this includes, but is not limited to nursery nurses, teachers or teaching assistants.

In this paper we develop a typology of ‘non-commercial’ approaches to farming, based on a survey of a representative sample of farmers in Scotland, United Kingdom. In total, 395 farmers indicated that they do not seek to make a profit on their farms. We estimate that these non-commercial approaches to farming are utilised on at least 13% of agricultural land in Scotland. As such, non-commercial farming is not a marginal practice, nor are NCF limited to small-scale ‘hobby’ farms: NCF exist (...) across the scale of agricultural holding sizes and are operated by a wide range of socio-demographic cohorts. We identify 6 types of NCF: agricultural residences, specialist smallholdings, horsiculture holdings, mixed smallholdings, amenity mixed farms, and large farms or estates. These types were differentiated primarily by the scale of farm size, presence of diversification activities and types of animal present. The analysis demonstrates a number of emergent patterns of land management: de facto land abandonment, transition towards ‘horsiculture’, and management differences between retiring and new entrant NCF. We argue that the types identified reflect a number of intersecting issues in contemporary agrarian transitions, particularly the aging farmer population; generational renewal; and gendered implications of agricultural restructuring.

Risk taking is a component of the decision-making process in situations that involve uncertainty and in which the probability of each outcome – rewards and/or negative consequences – is already known. The influence of cognitive and emotional processes in decision making may affect how risky situations are addressed. First, inaccurate assessments of situations may constitute a perceptual bias in decision making, which might influence RT. Second, there seems to be consensus that a proneness bias exists, known as risk proneness, which (...) can be defined as the propensity to be attracted to potentially risky activities. In the present study, we take the approach that risk perception and risk proneness affect RT behaviours. The study hypothesises that locus of control, emotion regulation, and executive control act as perceptual biases in RT, and that personality, sensation seeking, and impulsivity traits act as proneness biases in RT. The results suggest that locus of control, emotion regulation and executive control influence certain domains of RT, while personality influences in all domains except the recreational, and sensation seeking and impulsivity are involved in all domains of RT. The results of the study constitute a foundation upon which to build in this research area and can contribute to the increased understanding of human behaviour in risky situations. (shrink)

The philosophy of science took shape as an autonomous discipline in the first decades of the Twentieth Century in connection with the movement known as logical positivism or logical empiricism. According to logical empiricists philosophy of science ought to perform a “rational reconstruction” aimed at exhibiting the logical structure of scientific theories and inferential processes involved in the acquisition of scientific knowledge. While focusing on the syntactical and semantical aspects of scientific language, logical empiricists left out of the realm of (...) the philosophy of science the sociological and psychological aspects of theory formation, as well as all methodological aspects belonging to experimentation. Starting from the early Sixties this conception gradually changed, and philosophy of science underwent a radical transformation, leading to a significant broadening of its scope. New issues and problems were addressed, belonging to fields neglected by the traditional approach. This paper sketches the main features of the discipline as it is understood today as opposed to its traditional outlook, and suggests that the term “philosophy of the sciences” is better suited than “philosophy of science” to describe its present state.

The first part of the article deals with the theories of probability and induction put forward by Hans Reichenbach and Rudolf Carnap. It will be argued that, despite fundamental differences, Carnap's and Reichenbach's views on probability are closely linked with the problem of meaning generated by logical empiricism, and are characterized by the logico-semantical approach typical of this philosophical current. Moreover, their notions of probability are both meant to combine a logical and an empirical element. Of these, Carnap over the (...) years put more and more emphasis on the logical aspect, while for Reichenbach the empirical aspect has always been predominant. Seen in this light, Carnap's and Reichenbach's theories of probability can be taken to represent the Viennese and Berlinese mainstreams of the common logical empiricist approach. The second part of the article contrasts the position of these authors with that of the Bruno de Finetti, who is the main representative of the subjective interpretation of probability. Though the latter is sometimes associated with the position taken by Carnap in his late writings, it will be argued that the two are in many ways irreconcilable. (shrink)

This paper investigates the kind of empiricism combined with an operationalist perspective that, in the first decades of our Century, gave rise to a turning point in theoretical physics and in probability theory. While quantum mechanics was taking shape, the classical (Laplacian) interpretation of probability gave way to two divergent perspectives: frequentism and subjectivism. Frequentism gained wide acceptance among theoretical physicists. Subjectivism, on the other hand, was never held to be a serious candidate for application to physical theories, despite the (...) fact that its philosophical back-ground strongly resembles that underlying quantum mechanics, at least according to the Copenhagen interpretation. The reasons for this are explored. (shrink)

Richard Jeffrey has labelled his philosophy of probability radical probabilism and qualified this position as Bayesian, nonfoundational and anti-rationalist. This paper explores the roots of radical probabilism, to be traced back to the work of Frank P. Ramsey and Bruno de Finetti.
