The persistent educational challenges that fractions pose call for developing novel instructional methods to better prepare students for fraction learning. Here, we examined the effects of a 24-session, Cuisenaire rod intervention on a building block for symbolic fraction knowledge, continuous and discrete non-symbolic proportional reasoning, in children who have yet to receive fraction instruction. Participants were 34 second-graders who attended the intervention (intervention group) and 15 children who did not participate in any sessions (control group). As attendance at the intervention (...) sessions was irregular (median = 15.6 sessions, range = 1–24), we specifically examined the effect of the number of sessions completed on their non-symbolic proportional reasoning. Our results showed that children who attended a larger number of sessions increased their ability to compare non-symbolic continuous proportions. However, contrary to our expectations, they also decreased their ability to compare misleading discretized proportions. In contrast, children in the Control group did not show any change in their performance. These results provide further evidence on the malleability of non-symbolic continuous proportional reasoning and highlight the rigidity of counting knowledge interference on discrete proportional reasoning.

This study examines the ethical dilemmas and difficulties encountered by Portuguese school psychologists. As part of a larger survey, participants were asked about ethical issues faced in daily practice and asked to describe ethical incidents. Of the 477 respondents, 274 reported 441 ethically troubling or challenging situations. Responses were coded into a six-category system based on the code of ethics of Portuguese psychologists. Most of the reported dilemmas concerned privacy and confidentiality principles. Results are discussed in light of relevant literature (...) and international findings. Implications for the development of the profession and future research are provided. (shrink)

A alimentação é uma necessidade de todo o ser vivo, que só pode lutar contra a morte e crescer integrando no seu corpo elementos seleccionados do mundo exterior a que se chama alimentos. Como tantas outras necessidades vitais, a alimentação não pôde eximir-se à interferência religiosa, sob a forma de tabus e outros tipos de restrições, quer para evitar a infracção destas normas sob a forma de pecado, quer para tributar à divindade uma homenagem de latria sob a forma de (...) sacrifícios, quer ainda para compensar o prazer haurido da manducação. E assim se impuseram restrições alimentares e ritos, inicialmente sacrais, muitos dos quais subsistem sob formas de protocolo às vezes bem complicadas. Estas interdições versaram sobre certos tipos de alimentos considerados “impuros” e determinados troços do calendário considerados “de penitência”. Muitas destas normas ainda subsistem, outras perderam-se, mas outras há que nasceram (ou renasceram) como cogumelos. (shrink)

This paper analyses the role of foreign and local companies in shaping Brazilian positions on global sustainability. It deals with an empirical investigation of CSR practices of firms from the electronics, food, and personal care sectors in response to pressures of 'market' and 'non-market' stakeholders. The results demonstrate that CSR decisions by foreign and local firms are triggered by organisational considerations and anticipated economic gains. The degree of implementation of CSR activities by foreign firms is more advanced than that of (...) local firms. The survey also confirms the hypothesis that market stakeholders exert pressure on companies and positively influence CSR. Non-market stakeholders seem to have a minor effect on corporate social responsibility decisions. We conclude that the institutional environment is a critical determinant of the extent to which the dialogue between stakeholders and companies leads to the attainment of sustainable development.

The propositional view of communication states that every literal assertoric utterance of an indicative sentence expresses a proposition, and the audience understands those utterances only if she entertains the proposition(s) the speaker expressed. According to an important objection due to Ray Buchanan, the propositional view is ill‐equipped to handle meaning underdeterminacy. Using resources from situation semantics and MacFarlane's nonindexical contextualism, this article develops a view of literal communication close to the propositional view which overcomes Buchanan's underdeterminacy considerations while accounting for (...) the kind of indifference that typically characterizes speakers' intentions.

Indirect speech reports can be true even if they attribute to the speaker the saying of something weaker than what she in fact expressed, yet not all weakenings of what the speaker expressed yield true reports. For example, if Anna utters ‘Bob and Carla passed the exam’, we can accurately report her as having said that Carla passed the exam, but we can not accurately report her as having said that either it rains or it does not, or that either (...) Carla passed the exam or pandas are cute. This paper offers an analysis of speech reports that distinguishes weakenings of what the speaker expressed that yield true reports from weakenings that do not. According to this analysis, speech reports are not only sensitive to the informational content of what the speaker expressed, but also to the possibilities a speaker raises in making an utterance. As I argue, this analysis has significant advantages over its most promising competitors, including views based on work by Barwise and Perry : 668–691, 1981), views appealing to recent work on the notion of content parthood by Fine :199–226, 2016) and Yablo, and Richard’s : 605–616, 1998) proposal appealing to structured propositions.

According to standard assumptions in semantics, ordinary users of a language have implicit beliefs about the truth-conditions of sentences in that language, and they often agree on those beliefs. For example, it is assumed that if Anna and John are both competent users of English and the former utters ‘grass is green’ in conversation with the latter, they will both believe that that sentence is true if and only if grass is green. These assumptions play an important role in an (...) intuitively compelling picture of communication, according to which successful communication through literal assertoric utterances is normally effected thanks to our shared beliefs about the truth-conditions of the sentences uttered in the course of the conversation. Against these standard assumptions, this paper argues that the participants in a conversation rarely have the same beliefs about the truth-conditions of the sentences involved in a linguistic interaction. More precisely, it argues for Variance, the thesis that nearly every utterance is such that there is no proposition which more than one language user believes to be that utterance’s truth-conditional content. If Variance is true, we must reject the standard picture of communication. Towards the end of the paper I identify three ways in which ordinary conversations can be communication-like despite the truth of Variance and argue that the most natural amendments to the standard picture fail to explain them.

In two occasions a Bibliography of Structuralism has been published in Erkenntnis (1989, 1994). Since then a lot of water has flowed under the bridge and the structuralist program has shown a continuous development.

Say that an audience understands a given utterance perfectly only if she correctly identifies which proposition (or propositions) that utterance expresses. In ideal circumstances, the participants in a conversation will understand each other’s utterances perfectly; however, even if they do not, they may still understand each other’s utterances at least in part. Although it is plausible to think that the phenomenon of partial understanding is very common, there is currently no philosophical account of it. This paper offers such an account. (...) Along the way, I argue against two seemingly plausible accounts which use Stalnaker’s notion of common ground and Lewisian subject matters, respectively. (shrink)

Although we may find the concept of anomie in Greek thought, it is since Durkheim that the concept begins to be used specifically as a sociological concept. However, a theory of anomie only becomes consolidated since “Social Structure and Anomie” by Robert K. Merton (Merton 1938). The theory becomes important and conquers its space in the rest of the century as one of the most productive theories about deviance. In this study, based on a contemporary conception of scientific theory, that (...) of the structuralist metatheory, a reconstruction of Merton’s approach is proposed, allowing to make explicit the deep structure of the theory.

This paper provides an exploratory comparative assessment of the institutional pressures influencing corporate social responsibility in a developed country, UK, vs. a developing country, Brazil, based on a survey of different actors. Information on sustainability concerns, organizational strategies and mechanisms of pressure was collected through interviews with environmental regulatory agencies, financial institutions, media and non-governmental organizations. Our results confirm that the more advanced awareness and CSR responsiveness in the UK is a consequence of a predominance of coercive and normative forces (...) on the organizational field. The institutional forces tend to build a Brazilian organizational field that is relational based and risk intensive. The findings lend support to the view that CSR responses are unlikely to be easily transformed into uniform standardized practices across the globe. This paper contributes to a collective understanding of the organizational field and a common template for CSR in the context of developed and developing countries. (shrink)

This dissertation argues for Semantic Variance, the thesis that nearly every utterance is such that there is no proposition that more than one languge user takes to be that utterance's truth-conditional content. I argue that Semantic Variance is problematic for standard theories concerning the nature of communication, the epistemic significance of ordinary disputes, the semantics of speech reports, and the nature of linguistic competence. In response to the problems arising from the truth of Semantic Variance, I develop new accounts of (...) the transmission of relevant information, ordinary disputes, and the semantics of speech reports. Towards the end of the dissertation I outline a pluralistic account about the nature of communication and linguistic competence. (shrink)

This paper develops a puzzle about non-merely-verbal disputes. At first sight, it would seem that a dispute over the truth of an utterance is not merely verbal only if there is a proposition that the parties to the dispute take the utterance under dispute to express, which one of the parties accepts and the other rejects. Yet, as I argue, it is extremely rare for ordinary disputes over an utterance’s truth to satisfy this condition, in which case non-merely verbal disputes (...) are extremely rare. After examining various responses to the puzzle, I outline a solution using the framework of truthmaker semantics. (shrink)

The present work is immersed in the context of the contemporary philosophy of science, especially of the semanticist philosophy of the structuralist metatheory. Objectively, the work aims to reestablish the dialogue between the general philosophy of science and the special philosophy developed by scientists concerned with the fundamentals of their discipline, in this case, with sociologists. After presenting the Mertonian notion of middle range theory, the conception of theory that offers ME and, from that conception, a way of conceiving both (...) global intertheoretical relations and intertheoretical change will be presented. Finally, the analysis of the use of the notion of middle range theory in scientific practice will be made, analyzing the specific case of sociological research about organizations. (shrink)

This paper raises a new form of speaker error objection to the analysis of disputes as metalinguistic negotiations in cases in which disputants reject that analysis. It focuses on an obvious but underexplored form of speaker error: speakers’ misattribution of contents both to others and to themselves. It argues that the analyses of disputes that posit this type of speaker error are uncharitable in three different ways: first, by portraying speakers as mistaken interpreters of their interlocutors; second, by portraying speakers (...) as uncharitable interpreters of their interlocutors; third, by portraying speakers who retract their claims as mistaken interpreters of their own prior utterances. Taken together, these unfavorable consequences weigh significantly against the plausibility of this type of analysis for the cases in question. (shrink)

If Amelia utters ‘Brad ate a salad in 2005’ assertorically, and she is speaking literally and sincerely, then I can infer that Amelia believes that Brad ate a salad in 2005. This paper discusses what makes this kind of inference truth-preserving. According to the baseline picture, my inference is truth-preserving because, if Amelia is a competent speaker, she believes that the sentence she uttered means that Brad ate a salad in 2005; thus, if Amelia believes that that sentence is true, (...) then she must believe that Brad ate a salad in 2005. I argue that this view is not correct; on pain of irrationality, normal speakers can’t have specific beliefs about the meaning of the sentences they utter. I propose a new account, relying on the view that epistemically responsible speakers utter sentences assertorically only if they believe all the propositions which they think those sentences might mean.

While ethics in publishing has been increasingly debated, there seems to be a lack of a theoretical framework for making sense of existing rules of behavior as well as for designing, managing and enforcing such rules. This letter argues that systems-oriented disciplines, such as complexity science and human factors, offer insights into new ways of dealing with ethics in publishing. Some examples of insights are presented. Also, a call is made for empirical studies that unveil the context and details of (...) both retracted papers and the process of writing and publishing academic papers. This is expected to shed light on the complexity of the publication system as well as to support the development of a just culture, in which all participants are accountable. (shrink)

To maximize brain plasticity after stroke, several rehabilitation strategies have been explored, including the use of intensive motor training, motor imagery, and action observation. Growing evidence of the positive impact of virtual reality (VR) techniques on recovery following stroke has been shown. However, most VR tools are designed to exploit active movement, and hence patients with low level of motor control cannot fully benefit from them. Consequently, the idea of directly training the central nervous system has been promoted by utilizing (...) motor-imagery (MI) based brain-computer interfaces (BCIs). To date, detailed information on which VR strategies lead to successful functional recovery is still largely missing, and very little is known about how to optimally integrate BCI and VR paradigms for stroke rehabilitation. The purpose of this study was to examine the efficacy of a BCI-VR system using a MI paradigm for post-stroke upper limb rehabilitation on functional assessments, and related changes in MI ability and brain imaging. To achieve this, a 60 years old male chronic stroke patient was recruited. The patient underwent a 3-week intervention in a clinical environment, resulting in 10 BCI-VR training sessions. The patient was assessed before and after intervention, as well as on a one-month follow-up, in terms of clinical scales and brain imaging using functional MRI (fMRI). Consistent with prior research, we found important improvements in upper extremity scores (Fugl-Meyer) and identified increases in brain activation measured by fMRI that suggest neuroplastic changes in brain motor networks. This study expands on the current body of evidence as more data are needed on the effect of this type of interventions not only on functional improvement but also through brain imaging to study the effect of the intervention on plasticity.

Objectivo principal do presente artigo é mostrar até que ponto o evolucionismo darwinista inclui proposições centrais testáveis, para além de várias proposições acessórias também elas testáveis. Nesse sentido, o autor constrói um argumento no sentido de mostrar que as alegações de Karl Popper, segundo as quais não pode ser concedido estatuto de cientificidade ao darwinismo, carecem de fundamento. O autor defende também a necessidade de um questionamento firme em relação a todo e qualquer argumento fornecido pela ciência, pois nem a (...) capacidade de previsão nem a universalidade das leis são garantia de que a ciência, também ela, nunca caia em erro. /// Aim of the present article is to show that the doctrine of evolution defended by Charles Darwin is grounded on propositions that are verifiable, as are verifiable many of its secondary propositions. The author builds up an argument that goes in the direction of showing how the allegations by Karl Popper against the scientific nature of Darwinism are not grounded in reality. The author of the article also defends the necessity of a firm questioning in relation to each and every argument advanced by the practitioners of science, since nor its anticipatory capacity nor the universality of its laws are warrant enough that the science never falls into error.

Este artigo tem como objetivo pensar as figurações feministas e o devir-mulher a partir da arte para refletir sobre subjetividades inventivas. Em seu conteúdo, aborda-se o contexto do lugar da mulher na arte, desde o apagamento das mulheres até a reapropriação desse espaço pelos movimentos feministas. Para refletir sobre a arte, são apresentados os conceitos de devir e de figuração, bem como artistas que dialogam com esses conceitos. Sob o aporte teórico feminista, o trabalho aponta a arte como um meio (...) de resistência na produção de novas narrativas pelas figurações, além de um estado de devir como resistência, desconstrução e reconstrução, e um modo de viver mais libertário por parte das mulheres.Palavras-chave: Estética feminista. Arte. Devir-mulher. Subjetivação. AbstractThis article aims to think over the feminist figurations and the becoming-woman through art, in order to reflect on inventive subjectivities. In its content, women's place in art's context is addressed, from their erasure until their reappropriation by feminist movements. The concepts of becoming and figurations are presented to think over art, as well as artists that dialogue with those concepts. Under the feminist theoretical contribution, the present work features art as a way of resistance in the production of new narratives through figurations, while also recognizing the state of becoming as a means of resistance, a deconstruction and reconstruction process, and ultimately a more liberating way of life by women.Keywords: Feminist Aesthetics.

Este artigo pretende analisar o processo de entrada da arte no horizonte da estética. Para isso, Martin Heidegger acompanha alguns dos conceitos desenvolvidos pelos gregos, como por exemplo, a relação entre matéria e forma e a arte como mímesis. O filósofo alemão também explicita a ligação entre sujeito e objeto como o pressuposto da época de imagens de mundo. Considerando as intepretações oferecidas pelos pensadores modernos, Heidegger avalia como a obra de arte se torna um suporte para experiências sensíveis e (...) como o juízo de gosto associou a estética com a beleza e nossa sensibilidade.

Suppose I assert “Jim is rich”. According to negotiated contextualism, my assertion should be understood as a proposal to adopt a standard of wealth such that Jim counts as “rich” by that standard. Furthermore, according to negotiated contextualism, this is so in virtue of the semantic properties of the word “rich”. Defenders of negotiated contextualism (Khoo & Knobe in Noûs 52(1):109–143, 2016; Khoo in Philos. Phenomenol. Res. 100(1):26–53, 2020) claim that this view is uniquely well-placed to account for certain disagreement (...) data; for example, that if your standard for the application of the word “rich” is more constraining than mine, you can sensibly assert “no, Jim is not rich” without thereby making an incompatible claim. This paper outlines a simpler explanation of the data: speakers can sensibly reject a given assertion provided that they think that the asserted sentence is false in the context which they take to be relevant to that sentence’s interpretation. I argue that, combined with standard semantic tools, this explanation can account for the original data and for new empirical results. Along the way, I present new empirical data to argue against negotiated contextualism. (shrink)

RESUMEN La formación de profesionales competentes y comprometidos con el ideal de justicia social y solidaridad humana es un reto para las universidades médicas en Cuba. El protagonismo estudiantil en este contexto contribuye a formar jóvenes autodeterminados, críticos, reflexivos, que se hagan cargo de su desarrollo profesional y participen de forma creadora en la transformación de la sociedad. Se realizó una investigación cualitativa en la Universidad de Ciencias Médicas de Camagüey, con el objetivo de valorar la visión que tienen los (...) líderes estudiantiles sobre el protagonismo estudiantil, los factores que lo limitan y acciones para perfeccionarlo. Se utilizaron las técnicas entrevista estructurada, entrevista grupal y observación participante a una muestra de once dirigentes estudiantiles. Se logró identificar que los dirigentes estudiantiles tienen una visión acertada sobre el protagonismo estudiantil y señalan factores que limitan el protagonismo, asociados a los propios estudiantes, los profesores, las autoridades universitarias y la institución. ABSTARCT The formation of competent and committed professionals with the ideal of social justice and human solidarity is a challenge for the medical universities in Cuba. The student-leading role in this context helps to form self-determined, critical, reflective young people, who take charge of his professional development and take part of creative form in the transformation of the society. A qualitative investigation was carried out in the University of Medical Sciences, with the objective to value the vision that the student leaders have on the student-leading role, the factors that limit it and actions to perfect it. There used the techniques structured interview, group interview and taking part observation to a sample of eleven student leaders. It was identified that the student leaders have an appropriate vision on the student-leading role and indicated factors that limit the leading role, associated with the proper students, the teachers, the university authorities and the institution.
