In the world of television-making, the media industry relies on measurements from a people-meter panel in order to find out how many people watch a certain program or commercial on television. A people-meter panel is a special-purpose panel in which the television-watching behavior of household members is measured using a special device attached to television sets. The measuring device can also register the television-watching behavior of guests to the panel homes. The reliability of estimates based on the people-meter panel primarily (...) depends on the sample size. Due to the complexity of the sample design, the effective sample size cannot be determined straightforwardly. This is even more the case when one incorporates the viewing behavior of guests. This paper describes a methodology that determines effective sample sizes by computing design effects and which extends the methodology in such a way that it incorporates ‘guest viewing’. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Let us say that an extended object is “composed wholly of simples” just in case it is an aggregate of absolutely unextended parts spread throughout an extended region—that is, just in case there is a set S such that: every member is a point-sized part of the object, and for every x, x is part of the object if and only if it has a part in common with some member of S. Could a truly extended substance be composed entirely (...) of unextended parts? Reflection upon the fact that it must be at least possible for extended objects to touch one another suggests that the answer to this question is: No. (shrink)

What precisely, W. J. T.

It is commonly thought that exploitation is unjust; some think it is part of the very meaning of the word ‘exploitation’ that it is unjust. Those who think this will suppose that the just society has to be one in which people do not exploit one another, at least on a large scale. I will argue that exploitation is not unjust by definition, and that a society might be fundamentally just while nevertheless being pervasively exploitative. I do think that exploitation (...) is nearly always a bad thing, and wul try to identify the moral belief which makes most of us think it is. But I will argue that its badness does not always consist in its being unjust. (shrink)

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

This book addresses two basic questions: What is the proper philosophical analysis of the concept of substance? and What kinds of compound substances are there? The second question is mainly addressed by asking what relations among objects are necessary and sufficient for their coming to compose a larger whole. The first 72 pages of the book contain a short history of attempts to answer the first question, and a brief presentation of the analysis the authors defend at length in their (...) earlier book, Substance Among Other Categories. In the remaining 119 pages, the authors take up the second question. This order of presentation makes sense; but it may help to create a false impression in those who only glance at the first few pages—that this book is just a simplified version of the earlier one, with a little bit of history thrown in. It would be quite unfortunate, however, if very many potential readers get this impression; for it might discourage them from looking closely at the bulk of the book, which is new. The issues discussed in the later chapters are at the center of one of the most lively debates in contemporary metaphysics; and the position Hoffman and Rosenkrantz stake out is appealing and carefully articulated. Their views deserve careful attention from philosophers working on the metaphysics of persistence through time, personal identity, artifact identity, and mereology. (shrink)

I defend an alternative to the two traditional accounts of the relationship between metacognition and social cognition: metacognition as primary versus social cognition as primary. These accounts have complementary explanatory vices and virtues. They also share a natural assumption: that interpretation in terms of mental states is “spectatorial”, aiming exclusively for an objective description of the mental facts about self and others. I argue that if one rejects this assumption in favor of the view that interpretation in terms of mental (...) states also plays important regulative roles with respect to minds and behavior, a new and superior conception of the relationship between metacognition and social cognition comes into view. On this conception, person-level metacognitive concepts are socio-cognitive tools that shape us into better cognitive agents and more predictable cognitive objects, thereby enhancing our abilities at social coordination. Mastery of these metacognitive concepts relies on subpersonal, non-conceptual, procedural metacognition. This reconceptualization of the relationship between metacognition and social cognition combines the complementary explanatory virtues of the two traditional conceptions, while avoiding their complementary explanatory vices.

With each of our three criminal-law topics—defining offenses, apprehending suspects, and establishing punishments—we feel, I believe, strong moral resistance to the idea that our practices should be settled by a prospective-participant perspective. This becomes quite clear when we look at how the “reforms” suggested by institutional viewing might combine once we consider all three topics together: imagine a more extensive and swifter use of the death penalty in homicide cases coupled with somewhat lower standards of evidence; or think of backing (...) a strict-liability criminal statute with the death penalty. Of course, such “reforms” would increase the execution of innocents; but, their proponents will tell us, any penal system involves the punishment of some innocents, and, if it provides for the death penalty, the execution of some innocents. Moreover, why is it worse for innocents to be punished than for innocents to suffer an equivalent harm in some other way? Formulated from a prospective-participant perspective: Why not run a small risk of being innocently executed in exchange for reducing, much more significantly, the risk of dying prematurely in other ways?

This is a study that investigated the extent of use of the three principles of ethics – utility, morality, and justice – in managerial ethical decision making, in addition to the personal attitude towards them. It involved undergraduate and graduate business students (total N=163) from the Olayan School of Business in the American University of Beirut, Lebanon. Two kinds of measurements were done: self assessment, and testing with the Saschkin’ s Managerial Value Profile (1997). It showed that morality was the (...) overriding ethical principle used, especially in the graduate group (professionals). Business students still believed in the justice system despite the weakness of the country’s law. Utility was the least used, although males were found to be more utilitarian than females. Finally there was no relation between personal attitudes toward the three ethical principles, and the intentional behavior when faced with ethical dilemmas. The findings were discussed and recommendations were given. (shrink)

Although the same environmental regulations apply to all regions in China, legal enforcement can be different due to local economic development priorities. There is still a lack of knowledge about how regional disparities affect the operating performance results of the implementation of corporate environmental management practices, thus providing little information for foreign companies when they invest and develop their production base in China. To fill this research gap, this paper collects data from the Fortune 500 Chinese firms to investigate the (...) moderating role of regional disparities in affecting the performance results of corporate environmental management efforts based on the institutional theory. The disclosed corporate environmental responsibility practices serve as proxy to represent corporate environmental management practices. Content analysis approach was applied to collect and analyze CER practices published in the corporate reports of Chinese manufacturers. The results show that CER has a positive impact on operating income, while regional disparities influence the relationship between CER and corporate operating income. Specifically, CER and operating income are positively related in Eastern China; on the contrary, they are negatively related in Western China. This paper adds to the body of knowledge about environmental discrepancies in the same emerging economy, and provides insights for systematic consideration in terms of the issues of government environmental regulations and corporate environmental strategies.

Claims about ‘the meaning of life’ have tended to be made and discussed in conjunction with bold metaphysical and theological affirmations. For life to have meaning, there must be a comprehensive divine plan to give it meaning, or there must be an intelligible cosmic process with a ‘telos’ that a man needs to know if his life is to be meaningfully orientated. Or, it is thought to be a condition of the meaningfulness of life, that values should be ultimately ‘conserved’ (...) in some way, that no evil should be unredeemable and irrational. And it may be claimed that if death were to end our experience, meaninglessness would triumph. (shrink)

Decentralized clinical trials (DCTs) have the potential to advance the conduct of clinical trials, but raise several ethical issues, including obtaining valid informed consent. The debate on the ethical issues resulting from digitalization is predominantly focused on direct risks relating to for example data protection, safety, and data quality. We submit however, that a broader view on ethical aspects of DCTs is needed to touch upon the new challenges that come with the DCT practice. Digitalization has impacts that go beyond (...) its direct purposes, by shaping behaviors, experiences, social relations, and values. We examine four elements of the informed consent procedure that are affected by DCTs, while taking these soft impacts of technologies into account: (i) informing participants and testing understanding, (ii) freedoms in relation to responsibilities and burdens, (iii) trust in participant-researcher relations, and (iv) impacts on the concept of privacy. Our analysis reveals that a broad view is key for optimal conduct of DCTs. In addition, it provides insight into the ethical impacts of DCTs on informed consent. Technologies such as DCTs potentially have profound impacts which are not immediately addressed by the existing regulatory frameworks, but nonetheless important to recognize. These findings can guide future practices of DCTs to foster the important values of clinical research in this novel approach for conducting clinical trials. (shrink)

Despite clinical evidence of drug superiority, therapeutic modalities, like combination immunotherapy, are mostly considered cost-ineffective due to their high costs per life year(s) gained.

No one who cares about equal opportunity can derive much comfort from the present occupational distribution of working women. In the various industrial societies of the West, women comprise between one quarter and one-half of the national labor force. However, they tend to clustered in employment sectors – especially clerical, sales, and service J occupations – which rank relatively low in remuneration, status, autonomy, and other perquisites. Meanwhile, the more prestigious and rewarding managerial and professional positions, as well as the (...) major categories of blue-collar labor, remain largely a male preserve. In the same societies the average income earned by full-time female workers is one-half to two- J thirds that of their male counterparts. Although this disparity owes much to i other factors, including lower pay for work similar or even identical to that r standardly done by men, much of it can be explained only by the concentration of working women in traditional female job ghettos.

Prison work creates ethical challenges for which a training program was initiated for Dutch prison staff to foster their Moral Craftsmanship (MCS). The concept of MCS is not yet defined and operationalized in literature.

A document and literature study provided input for the definition and selection of conceptual elements related within DCIA policy documents, identifying three conceptual levels of (...)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Painting Outside the Lines: Patterns of Creativity in Modern ArtMatthew ZiffPainting Outside the Lines: Patterns of Creativity in Modern Art, by David W. Galenson. Cambridge: Harvard University Press, 2001, 272 pp., $29.95.The relationship between the market value of paintings and the chronological point in an artist's working life when the paintings were produced is the driving mechanism for exploring creativity and innovation in David W. Galenson's book "Painting (...) Outside the Lines: Patterns of Creativity in Modern Art. The working thesis of this book is that Modern artists have worked creatively and innovatively in one of two distinctly different manners. The terminology Galenson uses to describe these distinct ways of working are "finders" and "seekers." Finders are artists like Pablo Picasso, who at age 26, make startling and important innovations with little advance indication that such a burst is about to take place. Seekers are artists like Paul Cezanne, whospend their entire working lives engaged in the pursuit of a singular approach or achievement. The differences between these methodologies are carefully presented through the details of the working lives of a variety of Modern artists. French nineteenth century and early twentieth-century artists and mid-twentieth-century American artists are used as the source data for these comparisons.Early in the book Galenson presents lists of chronological events within the lives of artists and market valuation of their work within this chronology. The dramatic clarity of the relationships presented in this data sets the stage for the detailed information that follows. Factors that in some cases only partly, and in others nearly completely, explain an artist's way of working are offered through biographic information, information about the aesthetic and cultural milieu, and about the economic and educational structures that are predominant during the relevant time in the life of the artist.The relationship between the aesthetic and cultural milieu surrounding an artist and the capacity or inclination of an artist to be innovative is an important aspect of the book's analysis. The scope of the book is limited to Modern artists because of the shift that took place at the outset of Modern art, during the mid 1860s, that brought a strong emphasis on innovation and change for their own sake as an important characteristic within a work of art. This emphasis "created incentives for painters to produce new approaches to art" (p. 111). Prior to the time of Modern art, innovation and change were often unnecessary for an artist to be successful. Modern art introduced the demand that innovation and change be necessary ingredients in art, and therefore the search for innovation became a significant element within the work of many artists. The manner in which this search took place, as presented through the data at hand, reveals how individual artists viewed the need for innovation and change within their own [End Page 123] work. Paul Cezanne, for example, was aware of the impact that his painting was having on the art world, but he insisted that he was not yet finished with discoveries that would reveal the truest expression of his beliefs about aesthetic expression.In the American movement, "Abstract Expressionism," Galenson finds a useful counter example to the art scene in Paris. In the United States, especially during the 1940s and 1950s — the peak years of creative output by Abstract Expressionist artists — the demand for their work was quite low. There were few economically viable outlets for the work of de Kooning, Pollack, Rothko, and the others of this group. Consequently there is a shift in the chronological point at which these artists achieve market value success. Nearly all of these artists receivedrecognition at an older age than the French artists of the late nineteenth and early twentieth centuries.The thesis of the book, that there are two fundamentally different ways of working to produce works of art, is directly applicable to, and useful in, exploring issues of teaching and learning in design education. As a teacher of interior architecture I was interested to follow the details that Galenson presented in support of his analysis of the careers of numerous Modern artists.

Entrepreneurs who start a business to serve both self-interests and collective interests by addressing unmet social and environmental needs are usually referred to as sustainable entrepreneurs. Compared with regular entrepreneurs, we argue that sustainable entrepreneurs face specific challenges when establishing their businesses owing to the discrepancy between the creation and appropriation of private value and social value. We hypothesize that when starting a business, sustainable entrepreneurs feel more hampered by perceived barriers, such as the institutional environment and have a different (...) risk attitude and perception than regular entrepreneurs. We use two waves of the Flash Eurobarometer survey on entrepreneurship, which contains information on start-up motivations, start-up barriers, and risk perceptions of approximately 3000 business owners across 33 countries. We find that sustainable entrepreneurs indeed perceive more institutional barriers in terms of a lack of financial, administrative, and informational support at business start-up than regular entrepreneurs. Further, no significant differences between sustainable and regular entrepreneurs are found in terms of their risk attitudes or perceived financial risks. However, sustainable entrepreneurs are more likely to fear personal failure than regular entrepreneurs, which is explained by their varied and complex stakeholder relations. These insights may serve as an important signal for both governments and private capital providers in enhancing the institutional climate. (shrink)

We affirm the utility of integrative modeling, according to which it is advantageous to move beyond “one-at-a-time binary paradigms” through studies that position themselves within realistic multidimensional design spaces. We extend the integrative modeling approach to a target domain with which we are familiar, the consequences of bilingualism on mind and brain, often referred to as the “bilingual advantage.” In doing so, we highlight work from our group consistent with integrative modeling.

In order to study early human development while avoiding the burdens associated with human embryo research, scientists are redirecting their efforts towards so-called human embryo-like structures (hELS). hELS are created from clusters of human pluripotent stem cells and seem capable of mimicking early human development with increasing accuracy. Notwithstanding, hELS research finds itself at the intersection of historically controversial fields, and the expectation that it might be received as similarly sensitive is prompting proactive law reform in many jurisdictions, including the (...) Netherlands. However, studies on the public perception of hELS research remain scarce. To help guide policymakers and fill this gap in the literature, we conducted an explorative qualitative study aimed at mapping the range of perspectives in the Netherlands on the creation and research use of hELS. This article reports on a subset of our findings, namely those pertaining to (the degrees of and requirements for) confidence in research with hELS and its regulation. Despite commonly found disparities in confidence on emerging biotechnologies, we also found wide consensus regarding the requirements for having (more) confidence in hELS research. We conclude by reflecting on how these findings could be relevant to researchers and (Dutch) policymakers when interpreted within the context of their limitations. (shrink)

Despite the growing interest in societal impact in the business and society literature, there remains a notable gap in research on the impact of health interventions on physical and mental health and social welfare. To address this gap, we shift the unit of analysis to the intervention, akin to the level of analysis used in health research. Drawing on a curated subset of health interventions in the workplace from the public health literature, we argue that management scholars can adopt the (...) methods used by public health scholars to design and assess health interventions. By tapping into the rich insights gained from these studies, management scholars can propose evidence-based interventions and policies that can enhance health outcomes, improve productivity, and cultivate a healthier workplace atmosphere. Collaborating with public health researchers, business and society scholars can help create a new field of research on corporate health policy. (shrink)

From the beginning of history sounds have played a fundamentally important role in humanity’s development as ways of expression and of communication. However in contemporary western society, and indeed globally, we are experiencing an excess of speech and a relentless encouragement to expression. Such excess indicates a misunderstanding about what expression and dialogue should be. This condition encourages us to think about silence, solitude and contemplation and the role they might play in restoring the realm of personal understanding of the (...) Self and of one’s authentic experience of the Other. The purpose of this article is to explore the potency of a silence that arises from our participation in the world. We present first some ideas about silence as a human phenomenon. This is followed by an examination of silence and language, an investigation of silence in dialogue, and of its educational implications. The article concludes by emphasising the value of silence as potency in itself, assisting in recovering the expressive powers of language. We argue that it is important to understand the positive status of silence in order to recognise and avoid repressive speech and to introduce its potential for reflective learning. (shrink)

BackgroundDepressive disorders are a common form of psychiatric illness and cause significant disability. Regulation authorities, the medical profession and the public require high safety standards for antidepressants to protect vulnerable psychiatric patients. Ketamine is a dissociative anaesthetic and a derivative of a hallucinogen. Its abuse is a major worldwide public health problem. Ketamine is a scheduled drug and its usage is restricted due to its abuse liability. Recent clinical trials have reported that ketamine use led to rapid antidepressant effects in (...) patients suffering from treatment-resistant depression. However, various flaws in study designs, and possible biased reporting of results, may have influenced those findings. Further analyses of ketamine use are needed to ensure patient safety.DiscussionThe use of ketamine in research and treatment of depressive disorders is controversial. Recently, mental health professionals raised ethical concerns about an ongoing ketamine trial in the UK. Also, a Canadian agency reviewed the existing evidence and did not recommend prescribing ketamine to treat depressive disorders. Findings obtained from tightly controlled research settings cannot be easily translated to clinical practice as substance abuse is commonly comorbid with depressive disorders. An effective antidepressant should reduce severity of depressive symptoms without liability problems. Although the US FDA has not approved the use of ketamine to treat depressive disorders, some psychiatrists offer off-label repeat prescription of ketamine. Prescribing ketamine for treating depressive disorders requires substantial empirical evidence. Clinicians should also consider research findings on ketamine abuse. Depressive disorders can be chronic conditions and the current evidence does not rule out the risk of substance abuse after repeat prescription of ketamine. Off-label ketamine use in treating depressive disorders may breach ethical and moral standards, especially in countries seriously affected by ketamine abuse. This article presents two real-world clinical vignettes which highlight ethical principles and theories, including autonomy, nonmaleficience, fidelity and consequentialism, as related to off-label ketamine use.ConclusionWe urge clinicians to minimise the risk of harming patients by considering the empirical evidence on ketamine properties and attempting all standard antidepressant therapies before considering the off-label use of ketamine.
