This book offers both the theoretical background behind the minority effect, teachers' personal experiences as they experienced being a minority, and their analyses and insights for teaching diverse learners. This book uses real-life experiences of diverse people to illustrate that, if not understood and addressed, situational minorities at school or work are unlikely to perform at their highest potentials.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:On the Inconvenience of Other People by Lauren BerlantNicholas AdlerBerlant, Lauren. On the Inconvenience of Other People. Duke University Press, 2022. 256pp.An Ambivalent TriumphAttachment is a double-edged sword. This idea is the scaffolding of the late Lauren Berlant's pivotal work, Cruel Optimism (2011), which explores the idea that attachment to a collectively invested fantasy of "the good life" acts in disservice of personal growth and (...) lasting fulfillment. The Inconvenience of Other People ostensibly repeats this structure while reattributing the role of fantasy. The premise here is that attachments to other people act in disservice to the fantasy of personal sovereignty. Of course, both texts argue for collectivity and for a recasting of the ordinary that structures current fantasies. But while Cruel Optimism builds around the unavoidable condition of fantasy, Inconvenience takes relations within the present as its fundamentally unavoidable condition, specifically the drive to be in relation even though such relations are inconvenient. "People" in the work's title stands for any attachment, any person or thing to which we exist in relation. To be part of the world is to be constantly taking in and living with the objects around us. This constant process of adjustment generates constant friction with our fantasy of sovereignty, or control, over ourselves. In Berlant's words, "inconvenience is another way of pointing to the experience of nonsovereign relationality," making our inconvenience drive the urge to maintain and explore those nonsovereign relations despite the uncomfortable friction they produce (18). Berlant's final monograph investigates the complexities of living with that inconvenience as well the potential for "loosening [those inconvenient objects] and becoming loose with them" in order to make that inconvenience generative of new perspectives and approaches (150).The prospect of overhauling our relationship with inconvenience takes place on multiple registers, both in terms of the affective states that guide the experience of inconvenience and the frameworks that determine its expression in the world. Refiguring ambivalence and dissociation, [End Page 123] the traditional affective responses to inconvenience, as well as offering a more dynamic structure for engaging with inconvenience than that of the institution, Berlant demonstrates—in a contained and structured way—the very object-loosening for which the text advocates. Although the book is presented as a collection of "assays...clusters of actions that become forms of life that shift the pressures of being in relation," it is nonetheless broken into three distinct chapters that focus on the role of the inconvenient in political relations, sexual relations, and relations with the self (11). These chapters, respectively, take up the inconvenient with regard to infrastructure, ambivalence, and dissociation.To productively engage with inconvenience, it must be accommodated within a social infrastructure. The term infrastructure positions the material of lived relationality as more flexible than that of institutions and more legible than that of expressive causality. For Berlant, "infrastructures are productive, durationally extensive spaces for the pliable forms of life that people use to make rules and norms and other means of extending the world" (23). In Chapter 2, they invoke the concept of the commons, "an orientation toward life and value unbound by concepts of property as constituted by division and ownership," using it as a way to illustrate infrastructuralism in effect (82). The commons can refer to as concrete a physical space as the Boston Common, as explored through Ralph Waldo Emerson's "Nature," or as abstract an inheritance as shared language, as explored through Juliana Spahr's lyrical autobiography, The Transformation (2007).The commons of both Emerson and Spahr make use of the concept of analogy. For Emerson, it stands for "the separation within the nonsovereign relation [of the commons] that makes linking possible" (Berlant 94). Spahr takes a more critical approach, continuing Emerson's use of the term while shining light on the glitches that emerge when any analogy is examined too closely. Acknowledging the rhetorical gymnastics required to "figure equally valued social being" within "imperialist capitalist infrastructures" reveals every possible analogy as both grossly oversimplifying and only temporarily comprehensible (105). Objects within these commons are constantly adjusting and generating new relations. The sense of an ongoing dynamic is what Berlant hopes this... (shrink)

Business students have long been noted for their differential proclivity to engage in academic misconduct. Unfortunately, the potential for misconduct has been exacerbated in recent years by rapid advances in technology, easy access to information, competitive pressures, and the proliferation of websites that provide students access to information that allows them to directly circumvent the learning process. Using a convenience sample of 631 students matriculating in various business majors at four U.S. universities and structural equations modeling procedures, this study assesses (...) the effects of psychological factors on business students’ propensities to utilize the services of homework assistance websites. Specifically, we examine how “Dark Triad” personality traits (i.e., narcissism, Machiavellianism, and psychopathy) interact with Fraud Diamond elements to influence student decisions to engage the services of these websites. We find that each Dark Triad trait exerts a significant influence on at least one of the Fraud Diamond elements, which in turn have a significant direct or indirect positive association with students’ reported intentions to utilize, and reported utilization of, these websites.

As a result of numerous, highly publicized, ethical breaches, firms and their agents are under ongoing scrutiny. In an attempt to improve both their image and their ethical performance, some firms have adopted ethical codes of conduct. Past research investigating the effects of ethical codes of conduct on behavior and ethical attitudes has yielded mixed results. In this study, we again take up the question of the effect of ethical codes on ethical attitudes and find strong evidence to suggest that (...) business professionals employed at firms with ethical codes of conduct are significantly less accepting of ethically questionable behavior toward most stakeholders. One notable exception relates to ethical actions toward customers. (shrink)

BackgroundNational guidelines require programmes use subjective assessments of social support when determining transplant suitability, despite limited evidence linking it to outcomes. We examined how transplant providers weigh the importance of social support for kidney transplantation compared with other factors, and variation by clinical role and personal beliefs.MethodsThe National survey of the American Society of Transplant Surgeons and the Society of Transplant Social Work in 2016. Using a discrete choice approach, respondents compared two hypothetical patient profiles and selected one for transplantation. (...) Conditional logistic regression estimated the relative importance of each factor; results were stratified by clinical role and beliefs.ResultsFive hundred and eighy-four transplant providers completed the survey. Social support was the second most influential factor among transplant providers. Providers were most likely to choose a candidate who had social support, always adhered to a medical regimen, and had a 15 years life expectancy with transplant. Psychosocial providers were more influenced by adherence and quality of life compared with medical/surgical providers, who were more influenced by candidates' life expectancy with transplant. For providers concerned with avoiding organ waste, social support was the most influential factor, while it was the least influential for clinicians concerned with fairness.ConclusionsSocial support is highly influential in listing decisions and may exacerbate transplant disparities. Providers’ beliefs and reliance on social support in determining suitability vary considerably, raising concerns about transparency and justice. (shrink)

We critically review key lines of evidence and theoretical argument relevant to Machery's These include interactions between different kinds of concept representations, unified approaches to explaining contextual effects on concept retrieval, and a critique of empirical dissociations as evidence for concept heterogeneity. We suggest there are good grounds for retaining the concept construct in human cognition.

Bio‐banking in research elicits numerous ethical issues related to informed consent, privacy and identifiability of samples, return of results, incidental findings, international data exchange, ownership of samples, and benefit sharing etc. In low and middle income (LMICs) countries the challenge of inadequate guidelines and regulations on the proper conduct of research compounds the ethical issues. In addition, failure to pay attention to underlying indigenous worldviews that ought to inform issues, practices and policies in Africa may exacerbate the situation. In this (...) paper we discuss how the African context presents unique and outstanding cultural thought systems regarding the human body and biological materials that can be put into perspective in bio‐bank research. We give the example of African ontology of nature presented by John Samwel Mbiti as foundational in adding value to the discourse about enhancing relevance of bio‐bank research in the African context. We underline that cultural rites of passage performed on the human body in majority of communities in Africa elicit quintessential perspective on beliefs about handling of human body and human biological tissues. We conclude that acknowledgement and inclusion of African indigenous worldviews regarding the human body is essential in influencing best practices in biobank research in Africa. (shrink)

In spite of the interference manifested in the double-slit experiment, quantum theory predicts that a measure of interference defined by Sorkin and involving various outcome probabilities from an experiment with three slits, is identically zero. We adapt Sorkin’s measure into a general operational probabilistic framework for physical theories, and then study its relationship to the structure of quantum theory. In particular, we characterize the class of probabilistic theories for which the interference measure is zero as ones in which it is (...) possible to fully determine the state of a system via specific sets of ‘two-slit’ experiments.

The low rates of regular exercise and overall physical activity (PA) in the general population represent a significant public health challenge. Previous research suggests that, for many people, exercise leads to a negative affective response and, in turn, reduced likelihood of future exercise. The purpose of this paper is to examine this exercise–affect–adherence relationship from an evolutionary perspective. Specifically, we argue that low rates of physical exercise in the general population are a function of the evolved human tendency to avoid (...) unnecessary physical exertion. This innate tendency evolved because it allowed our evolutionary ancestors to conserve energy for physical activities that had immediate adaptive utility such as pursuing prey, escaping predators, and engaging in social and reproductive behaviors. The commonly observed negative affective response to exercise is an evolved proximate psychological mechanism through which humans avoid unnecessary energy expenditure. The fact that the human tendencies toward negative affective response to and avoidance of unnecessary physical activities are innate does not mean that they are unchangeable. Indeed, it is only because of human-engineered changes in our environmental conditions (i.e., it is no longer necessary for us to work for our food) that our predisposition to avoid unnecessary physical exertion has become a liability. Thus, it is well within our capabilities to reengineer our environments to once again make PA necessary or, at least, to serve an immediate functional purpose. We propose a two-pronged approach to PA promotion based on this evolutionary functional perspective: first, to promote exercise and other physical activities that are perceived to have an immediate purpose, and second, to instill greater perceived purpose for a wider range of physical activities. We posit that these strategies are more likely to result in more positive (or less negative) affective responses to exercise, better adherence to exercise programs, and higher rates of overall PA.

We address a previous finding in the business ethics literature in which accounting professionals in higher rank levels, i.e., “manager” or “partner” of auditing firms, appear to have lower moral reasoning ability than their junior counterparts. Prior investigations have relied upon a similar methodology for estimating ethical beliefs, namely testing “moral reasoning ability” using either the Moral Judgment Interview or Defining Issues Test. In the present study, we use a multiple vignettes approach to test for the existence of the inverse (...) rank-ethical beliefs effect. With only 2 of the 30 vignettes resulting in both managers and partners being more accepting of the ethically charged behaviors, the results presented here using this alternative methodology are generally not supportive of the inverse rank-ethical beliefs phenomenon. We also use a multivariate analysis in order to control for demographic characteristics. Our results suggest that the most robust predictor of ethical attitudes among accounting practitioners is age, not rank within a firm. (shrink)

Introduction: Variation across research ethics boards in conditions placed on access to medical records for research purposes raises concerns around negative impacts on research quality and on human subject protection, including privacy.Aim: To study variation in REB consent requirements for retrospective chart review and who may have access to the medical record for data abstraction.Methods: Thirty 90-min face-to-face interviews were conducted with REB chairs and administrators affiliated with faculties of medicine in Canadian universities, using structured questions around a case study (...) with open-ended responses. Interviews were recorded, transcribed and coded manually.Results: Fourteen sites required individual patient consent for the study to proceed as proposed. Three indicated that their response would depend on how potentially identifying variables would be managed. Eleven sites did not require consent. Two suggested a notification and opt-out process. Most stated that consent would be required if identifiable information was being abstracted from the record. Among those not requiring consent, there was substantial variation in recognising that the abstracted information could potentially indirectly re-identify individuals. Concern over access to medical records by an outside individual was also associated with requirement for consent. Eighteen sites required full committee review. Sixteen allowed an external research assistant to abstract information from the health record.Conclusions: Large variation was found across sites in the requirement for consent for research involving access to medical records. REBs need training in best practices for protecting privacy and confidentiality in health research. A forum for REB chairs to confidentially share concerns and decisions about specific studies could also reduce variation in decisions. (shrink)

We survey students at two Southern United States universities (one public and one private, religiously affiliated). Using a survey instrument that includes 25 vignettes, we test two important hypotheses: whether ethical attitudes are affected by religiosity (H1) and whether ethical attitudes are affected by courses in ethics, religion or theology (H2). Using a definition of religiosity based on behavior (church attendance), our results indicate that religiosity is a statistically significant predictor of responses in a number of ethical scenarios. In seven (...) of the eight vignettes for which religiosity is significant, the effect is negative, implying that it reduces the acceptability of ethically-charged scenarios. Completion of ethics or religion classes, however, was a significant predictor of ethical attitudes in only two of the 25 vignettes (and in the expected direction). We also find that males and younger respondents appear to be more accepting of the ethically-questionable vignettes. We conclude that factors outside of the educational system may be more influential in shaping responses to ethical vignettes than are ethics and religion courses. (shrink)

In 1897, Cambridge University created a professorship in Mental Philosophy and Logic; despite the double name it was filled by a “mental philosopher,” James Ward, who did no work in logic. The chief logician candidate, John Venn, then turned his attention elsewhere, leaving Cambridge without senior leadership in logic. Ward himself turned to other philosophical issues, doing little further original work in mental philosophy. Cambridge became a center for a fresh interpretation of logic in the early 20th century, but with (...) no help from Venn. Psychology split off from mental philosophy, and what remained, the “philosophy of mind,” was developed elsewhere until after Ward’s tenure. (shrink)

O presente artigo pretende discutir a apropriação que Maurice Blondel faz da fenomenologia na esfera da ciência da ação. Ao lidar com todas as coisas como fenômenos, Blondel reivindica um sentido próprio, adequado ao seu caminho filosófico que, no lidar imanente com as coisas, percebe um remetimento ao sentido transcendente e, em última instância, ao Ser. Desta forma, pensar uma fenomenologia significa lidar com as questões de sentido como um todo, tendo em vista um arcabouço transcendente. É neste argumento que (...) se estrutura a ação, tomada como uma hermenêutica dos fenômenos. (shrink)

Este artigo aborda de maneira preliminar a efetivação das políticas públicas educacionais no Assentamento Roça do Povo, no município de Itabuna-BA, analisando a legislação vigente, pontuando direitos conquistados pelas populações rurais e principalmente pelos campesinos por meio das suas lutas e reivindicações. Também foram analisadas as dificuldades, desafios, progressos, formação de professores e a importância da educação no campo para os campesinos. Desta forma, abordamos a importância de conhecer e estudar as leis que regulamentam a Educação do Campo, pois, a (...) prática educacional deve ser condizente com a realidade cotidiana, buscando valorizar a identidade e a cultura do campesinato. Além disso, este estudo visa ainda valorizar e defender a importância da educação no campo. Por fim, a presente pesquisa busca difundir as informações coletadas no Assentamento Roça do Povo, objetivando provocar inquietação na sociedade e aos órgãos públicos, para que possam olhar com maior atenção para a Educação do Campo e compreender a importância dela para os campesinos no Brasil, em especial na Bahia.

Neste artigo pretendemos discutir qual o papel da autoridade na formação dos indivíduos, tendo como base o pensamento de T. W. Adorno, nos aprofundando especificamente em suas reflexões do livro Educação e Emancipação. Explicarei a importância que a família tem na formação, sobretudo, a figura de autoridade paterna durante a infância, e como ela sofreu mudanças na passagem do capitalismo liberal para o capitalismo tardio. Essas mudanças têm grande impacto na formação, pois, a partir da perda de autoridade da família (...) no capitalismo tardio, vemos a conseqüente fragilização da individualidade. Influenciado pela psicanálise de Freud, o pensador frankfurtiano faz uma crítica social muito profunda, mostrando como acontecimentos políticos e econômicos estão ligados ao processo de formação e como influenciam na estrutura psíquica dos indivíduos (criação do superego), tendo reflexos em sua personalidade e comportamento. Com a decadência do capitalismo liberal e da família burguesa a figura paterna não exerce mais a autoridade que exercia outrora. Assim, o complexo edipiano não é resolvido, podendo originar uma personalidade autoritária, contudo, esta etapa de identificação deve ser superada, ela é apenas uma fase importante para incorporação de normas básicas para a vida social durante a primeira infância. Após esta fase o indivíduo passa por um processo de amadurecimento, começa a elaborar as regras internalizadas conforme sua experiência de vida, passa a confrontar seus ideais da infância com a sua realidade presente e, conseqüentemente, reflete de maneira crítica.

This text examines the tensions and the dissonances in the relation between religion and public sphere in contemporary Brazil. Based on a Sociology and on an Anthropology of the phenomena of secularization and secularity, the purpose is to demonstrate the “porosity” of the Brazilian public/political system with the religious milieu. By applying a socio-historical perspective, the work attempts to understand how the boundaries between religion and politics were precariously constructed throughout the constitution of our State in Brazil, without ever having (...) been institutionally well-delimited. This vacuum, which generated concessions on the part of the State to major Christian religions, guaranteed public legitimacy to their religious symbols in official state spaces, which are, in principle, neutral and secular. However, the 1988 Constitution represented the influx of modern and secular legislation that legitimized subjects of rights such as women, black people, indigenous peoples, LGBTs, environmentalists, etc. Given that background, this reflection aims at contributing to the interpretation of the complexity involved in the multiple and contradictory presence – in the public sphere – of both major Christian religions – which are based on an agenda of conservative religious values – and liberal and libertarian projects organized by segments of civil society and public agents, which generate tensions and dissonances. To understand this reality – as a mosaic of interactions and antagonisms –, we work with the notion of “pluri-confessionality” of Mexican sociologist Roberto Blancarte and also with the notions of secularity of “recognition” and of “integration” of French political scientist Philippe Portier. Hence, we attempt to reach theoretically and empirically a broader and nuanced understanding of our public-political system in the relation with the religious dimension. (shrink)

Recent high-profile corporate scandals are reminiscent of the corporate raider scandals of the 1980s, suggesting that ethical scandals may occur in waves. This article provides a framework for analysis of this question by suggesting that ethical attitudes may be cyclical about long-term secular trends. We provide some empirical evidence from previously published work for the existence of cycles as well as a potential mechanism for their propagation, namely widespread publicity about a particularly salient event, e.g., Enron. Further, we posit that (...) long-run secular trends would be affected through more deliberate, cognitive means, e.g., instruction in business ethics. We also discuss an important research implication, namely that traditional cross-sectional “book-end” studies surveying ethical attitudes at two different points in time may be unable to disentangle short-run cyclical movements from long-term secular trends.

O espaço geográfico é uma categoria da ciência geográfica que possibilita uma acentuada e complexa possibilidade de refletir a coletividade social, sendo que neste desafio são trazidas à tona inúmeras perspectivas de análises da relação homem-natureza. Dessa feita, o presente estudo elabora uma breve discussão acerca do espaço geográfico enquanto uma ferramenta de análise das relações sociais, além de evidenciar a sua centralidade no interior da Geografia. Ao longo do estudo estão colocadas algumas concepções teóricas desta categoria geográfica, com destaque (...) para os entendimentos elaborados pela Geografia Crítica, uma reflexão que propõem a necessidade de se politizar os sujeitos por intermédio do ensino, com destaque para os conteúdos geográficos ensinados por seus respectivos professores desde os primeiros anos do ensino fundamental. A busca aqui foi a de confirmar a capacidade que a Geografia possui em se utilizar do próprio espaço geográfico na qual os alunos estão inseridos enquanto materialidade para uma concepção própria de mundo, sendo que através desta conquista, se permite compreender e pensar a construção de uma sociedade pela e para a própria coletividade envolvida. É esta a grande questão discorrida no presente ensaio, pensar uma proposta de ensino na geografia que politize os sujeitos, permitindo assim a formação de sujeitos ativos e cientes do seu papel no mundo.

El artículo da cuenta que la historia constitucional chilena se encuentra vinculada a las nociones de orden y estabilidad. Esta situación se manifiesta de manera particular en la Constitución de 1980, fruto del régimen de un gobierno de facto que implantó un sistema constitucional fundado en una comprensión liberal de la democracia, la cual se fundamenta y se legitima por su uso. Se apuesta por una reforma a la Carta, la que actualmente opera fuera de los fines de toda Constitución, (...) restringiendo la participación ciudadana. Particular atención merecen las manifestaciones que tienen lugar hoy y que reflejan cómo el régimen constitucional impide poner sobre la mesa de discusión con el Gobierno un ideal de educación que abandone una democracia instrumental y que recoja principios republicanos.

Caplan & Waters's arguments for separate working memory subsystems for “interpretive” and “post-interpretive” comprehension processes do not have a solid empirical basis. The likely involvement of a separate phonological loop makes their memory-load data irrelevant to theory evaluation, and the lack of statistical power from nonoptimal experimental designs and analyses unfairly reduces the chances of detecting the relevant interactions.

O presente trabalho trata dos usos que destacados filósofos italianos têm dado à noção de biopolítica. O estudo é a continuação do diálogo transdisciplinar entre a filosofia da educação e a agroecologia. P arte da pesquisa de doutorado na área de educação, onde se analisaram as práticas pedagógicas da agroecologia, o qual denominamos como agroecopedagogia. Utilizando a ferramenta arqueogenealógica, a pesquisa indagou pelas relações de poder veiculadas em ditas práticas. Aqui apresentamos parte dessa discussão, incorporando também a chamada ecopedagogia. Como (...) se sabe a biopolítica é uma noção antiga atualizada pelos trabalhos do pensador francês Michel Foucault e a qual abriu uma série de importantes debates no pensamento crítico, especialmente, em questões relacionadas a um suposto progresso da humanidade atrelado à relação saber-poder. Neste artigo descrevemos como dois de seus comentadores mais importantes interpelaram a re-leitura da biopolítica por parte do filósofo do poder criando assim tensões para as pedagogias que tem como fundamento o saber ecológico. Inicialmente, abordamos a duplicidade da biopolítica, presente no livro Bíos, Biopolítica y filosofía de Roberto Esposito, articulada como a política da vida e a política sobre a vida ; desta abordagem por parte do professor italiano surgem duas noções chaves para tensionar a ecopedagogia: comunitas/ immunitas. Seguidamente, introduzimos a discussão apresentada pelo também italiano, Giorgio Agamben a partir de duas de suas obras mais comentadas no campo da filosofia da educação, Estado de exceção e Homo Sacer: O poder soberano e a vida nua. A nosso ver, os comentários do Agamben oferecem uma radical discussão em torno da diferença e da democracia, o que nos parece levar a um nível de tensão insuspeitado o discurso agroecológico e a educação ambiental em seu princípio crítico vinculado a um desejo de emancipação, libertação e transformação; de tal forma que esta radical discussão se torna de uma importância vital não só para a própria coerência das práticas supracitadas, mas de forma geral, para um mundo por-vir delimitado cada vez pelo biopoder.

Neste artigo discute-se a relação entre turismo, fé e religião em torno dos santuários, a partir de três vivências etnográficas revisitadas em forma de flashes multissituados, com revisão bibliográfica parcial. O santuário, em sentido lato, abarca um núcleo central e uma extensa franja, espaciais e simbólicos. Entre o centro e a periferia estendem-se gradações, continuidades e descontinuidades. O santuário, desta forma, é compreendido neste artigo mais por suas sombras e simulacros do que por sua luminosa presença e esplendor, mais pela (...) periferia do que pela centralidade. A questão proposta aqui remete aos espaços intermediários onde religião e turismo se esbarram, se misturam e se contrapõem. Foram três os espaços estudados a partir da metodologia etnográfica, Aparecida, Canção Nova e Ashram-Vrajabhumi. O presente texto defende, portanto, que as franjas dos santuários permitem a reverberação de identidades ambíguas e oscilantes entre uma integridade-unicidade e uma não-integridade/não-unicidade.

Epistemologists are interested in what makes beliefs well justified. Even before considering competing theories of epistemic justification, however, we should ask what sort of valuational structure we are trying to explain. If, as far as epistemic justification is concerned, beliefs are like bank accounts, then all beliefs are comparable: just as in any bank account there must be more, less, or as much money as in any other, one belief must be better, worse, or as good as any other. Contemporary (...) epistemologists take for granted the assumption that beliefs are comparable in the same way that bank accounts are comparable: bank accounts have balances, sprinters have personal bests for the 100-meter dash, and beliefs have degrees of justifiedness. Alternatively, we could understand the justificatory status of a belief to be more like the expensiveness of a restaurant. Consider a concept of restaurant expensiveness on which the expensiveness of a restaurant is determined by the range of prices for meals at that restaurant. If meals at Restaurant A are $25 to $50 and meals at B are $10 to $20, then A is more expensive than B. Restaurant C, however , is neither more nor less expensive than A. Nor is it equally expensive, for there are restaurants that are more expensive than C that are not more expensive than A . Some evaluative concepts, like this concept of restaurant expensiveness, do not reduce values to single numbers. If epistemic justification is like this, then there may be pairs of beliefs such that neither is better justified than the other, but nor are they equally well justified. Such beliefs would be incomparable. While incomparability is familiar in the ethics literature, it has not previously been explored in epistemology. I discuss the implications of allowing for incomparability in epistemology, both for theories of epistemic justification and theories of knowledge. (shrink)

Contemporary epistemologists assume a view I call ‘comparabilism.’ They do not, however, argue for this view. I claim that noncomparabilism is a viable alternative. I further argue that noncomparabilism has advantages over comparabilism.

Two recent publications highlight the role of bone‐forming cells, the osteoblasts, in controlling the development of neighboring haematopoietic stem cells (HSCs).1,2 Using two distinct transgenic mouse models, one using the conditional deletion of the Bone Morphogenetic Protein Receptor 1A (BMPR1A) gene, the other using over‐expression of an active PTH/PTHrP receptor (PPR) mutant within osteoblasts, the authors show parallel, concordant increases in the generation of trabecular osteoblasts and the number of HSCs. In situ staining showed that rarely cycling HSCs sporadically attach (...) to endosteal osteoblasts, while in vitro assays indicated that ligation of Jag1 on osteoblasts by Notch1 on HSCs promotes HSC proliferation. These two independent works have revived and revitalized the notion that osteoblasts are a major, defining component of the HSC niche within the bone marrow (BM). This minireview discusses these results in the context of other recent studies of mesenchymal cells within the BM microenvironment, presents one potential unified model of the functional anatomy of the BM HSC niche, and highlights new questions raised by these and other studies of osteoblasts and HSCs.
