In this study, we aim to disentangle pantomime from early signs in a newly-born sign language: Sao Tome and Principe Sign Language. Our results show that within 2 years of their first contact with one another, a community of 100 participants interacting everyday was able to build a shared language. The growth of linguistic systematicity, which included a decrease in use of pantomime, reduction of the amplitude of signs and an increase in articulation economy, showcases a learning, and social interaction (...) process that constitutes a continuum and not a cut-off system. The human cognitive system is endowed with mechanisms for symbolization that allow the process of arbitrariness to unfold and the expansion of linguistic complexity. Our study helps to clarify the role of pantomime in a new sign language and how this role might be linked with language itself, showing implications for language evolution research. (shrink)

Margaret Archer plays a leading role in the sociological analysis of the relation between structure and agency, and particularly in the study of reflexivity. The main aim of this article is to discuss her approach, focusing on the main contributions and limitations of Archer’s theory of reflexivity. It is argued that even though her research is a pioneering one, proposing an operationalization of the concept of reflexivity in view of its empirical implementation, it also minimizes crucial social factors and the (...) dimensions necessary for a more complex and multi-dimensional study of the concept, such as social origins, family socialization, processes of internalization of exteriority, the role of other structure–agency mediation mechanisms and the persistence of social reproduction.

Drawing from Goffman’s original observations on stigma and the consequences of interactions between the stigmatized and supportive or stigmatizing audiences, we conduct a 20-year review of the diverse literature on stigma to revisit the collective nature of stigmatization processes. We find that studies on stigma’s origins, responses, processes, and outcomes have diverged from Goffman’s relational view of stigma as they have overlooked important relational mechanisms explaining the processes of (de)stigmatization. We draw from those conclusions to justify the need to study (...) stigma as a collective phenomenon. We develop a relational perspective on stigma based on understanding how attributes are stigmatized (or not) by audiences in their interactions. We argue that to advance stigma research, it is necessary to build on Goffman’s theory to include the stigmatizers (i.e., the normal) and supporters (i.e., the wise); how they create, sustain, or remove stigma; and how they relate to the stigmatized (i.e., the targets). Accordingly, we provide a research agenda on stigma as a collective phenomenon that theorizes a relational perspective, proposes a typology of how audiences relate to stigmatization, and identifies patterns of relations between audiences. We thus offer a missing piece to existing accounts of stigma by focusing on the key role of audiences (i.e., stigmatizers or supporters of the stigmatized) rather than on the targets of stigma (i.e., the own).

Studies of creative industries typically contend that creative work is profoundly precarious, taking place on a freelance basis in highly competitive, individualized and contingent labour markets. Such studies depict creative workers as correspondingly self-enterprising, self-reliant, self-interested and calculative agents who valorise care-free independence. In contrast, we adopt the ‘ethics of care’ approach to explore, recognize and appreciate the communitarian, relational and moral considerations as well as interpersonal connectedness and interdependencies that underpin creative work. Drawing on in-depth interviews with creative workers (...) in a range of marginal socio-cultural contexts, we argue that creative workers cultivate and sustain a diverse array of practices of care arising from an affective concern with the well-being of others. Far from being merely individualistic and crudely competitive actors, creative workers enact practical ethical responsibilities and affectivities towards a range of human and non-human others, including families, local communities and neighbourhoods, colleagues, artistic scenes and their adjacent genres, and surrounding national and linguistic cultures. In emphasizing the fundamental and structuring role of care in contingent labour markets our approach accords with recent trends in the social sciences that ‘affirmatively’—as opposed to ‘negatively’ and ‘suspiciously’—recognize that mutuality, solidarity and affectivity are powerful drivers of action on a par with or even exceeding market-driven self-centredness.

Flexibility in conceptual projection constitutes one of the most challenging issues in the embodiment and conceptual metaphor literatures. We sketch a theoretical proposal that places the burden of the explanation on attentional dynamics in interaction with mental models in working memory that are constrained to be maximally coherent. A test of this theory is provided in the context of the conceptual projection of time onto the domain of space. Participants categorized words presented at different spatial locations (back–front, left–right) as referring (...) to the past or to the future. Responses were faster when the irrelevant word location was congruent with the back–past, front–future metaphoric mapping. Moreover, when a new highly task-relevant spatial frame of reference was introduced, it changed the projection of past and future onto space in a way that was congruent with the new frame (past was now projected to left space and future to right space), as predicted by the theory. This study shows that there is substantial flexibility in conceptual projection and opens a venue to study metaphoric variation across tasks, individuals, and cultures as the result of attentional dynamics.

Considering recent theoretical discussions about the concept of moral legitimacy, this study advances our understanding of its performance consequences. Specifically, it uncovers the mediating role of moral legitimacy in the relationship between regulations and industry performance. Our analysis of the U.S. state-level data on regulations in a controversial industry between 1994 and 2010 yields four significant findings. The results show that regulations not only decrease performance but also negatively impact moral legitimacy. Moreover, this study provides empirical evidence that moral legitimacy (...) is positively related to industry performance, providing much-needed direct support for this premise. Importantly, the results indicate that moral legitimacy mediates the effect of regulations on performance, but only when regulations are aligned with moral values. Overall, this study extends our understanding of how regulations influence moral legitimacy, and in turn impact industry performance. (shrink)

In this study we examined whether parents’ perceptions of students’ anxiety as well as perceived support from both teachers and classmates were predictive of changes in students’ academic motivation during the first wave of COVID-19. To this end, we used a retrospective pretest-posttest design together with a latent change score model to analyze our data. From April to May of 2020, 394 Portuguese parents of students in grades 1–9 participated in this study. Our results showed that students’ anxiety and teachers’ (...) social support, as perceived by parents, were highly significant predictors of academic motivation changes. Specifically, we found a negative effect of anxiety and a positive effect of teachers’ social support on students’ academic motivation. Our results did not show, however, a significant predictive role of classmates’ social support. This study provides an important contribution to further understand the intrapersonal and interpersonal factors that are associated with the decline of students’ academic motivation during the COVID-19 pandemic. The pivotal role of teachers in sustaining students’ academic motivation and other relevant educational implications for the ongoing pandemic are discussed. (shrink)

This paper discusses an algorithmic tool introduced in the Basque Country (Spain) to assess the risk of intimate partner violence. The algorithm was introduced to address the lack of human experts by automatically calculating the level of violence based on psychometric features such as controlling or violent behaviour. Given that critical literature on risk assessment tools for domestic violence mainly focuses on English-speaking countries, this paper offers an algorithmic accountability analysis in a non-English speaking region. It investigates the algorithmic risks, (...) harms, and limitations associated with the Basque tool. We propose a transdisciplinary approach from a critical statistical and legal perspective. This approach unveils issues and limitations that could lead to unexpected consequences for individuals suffering from partner violence. Moreover, our analysis suggests that the algorithmic tool has a high error rate on severe cases, i.e., cases where the aggressor could murder his partner—5 out of 10 high-risk cases are misclassified as low risk—and that there is a lack of appropriate legal guidelines for judges, the end users of this tool. The paper concludes that this risk assessment tool needs to be urgently evaluated by independent and transdisciplinary experts to better mitigate algorithmic harms in the context of intimate partner violence.

This article refers to selected issues elaborated from my interdisciplinary doctoral thesis accomplished at the University of South Africa in 2019. I investigated the ethical-theoretical frameworks as well as practices of Christian humanitarian non-governmental organisations in Germany by combining a theoretical part and an empirical part. The empirical part was accomplished by interviewing 11 NGOs from the humanitarian field. The findings of theory and practice showed that many Christian NGOs typically conform to the secular mindset and regulations in order to (...) be able to function as organisations. The results also revealed that Christian NGOs have difficulties in defining their identity in order to be attractive and convincing to their current and prospective employees and donors. In addition, organisational and hierarchical structures are mostly taken from business companies but do not necessarily always fit to the individual organisations. The research is significant because it shows to what extent these NGOs experience tensions and insecurities having to work in a secular environment, and it helps to identify some typical challenges that Christian organisations face in Western countries. The purpose of the thesis was to impact on the reflection and practice of leaders of NGOs in their quest to understand developments and paradigm shifts, and ensure that they will act in a recognisably Christian way.Contribution: This article has been held as a presentation at the Leadership Conference in Pretoria, South Africa, in 2019. It contributes to the research of specific Christian leadership, and particularly of leadership in Christian non-governmental organisations. This article aims to describe the challenges these organisations face, having to work in the midst of a secular environment. (shrink)

We adopt the largest consistent set defined by Chwe (1994; J. Econ. Theory 63: 299–325) to predict which coalition structures are possibly stable when players are farsighted. We also introduce a refinement, the largest cautious consistent set, based on the assumption that players are cautious. For games with positive spillovers, many coalition structures may belong to the largest consistent set. The grand coalition, which is the efficient coalition structure, always belongs to the largest consistent set and is the unique one (...) to belong to the largest cautious consistent set. (shrink)

In her recent book Gillian Brock argues that states’ legitimacy depends on their being part of a just state system that protects human rights. Here I discuss some practical limitations raised by Brock’s legitimacy framework: mainly, (1) the problematic real-world implications of such an account, and (2) the epistemic challenges that judgements inspired by this account would have to face, were we to proceed solely on the basis of it.

Online education has become an essential component of education. Thus, several factors, such as the student’s learning strategy and motivation, generally contribute to their academic success. This study investigates the relationship between learning strategies, motivation, and online learning environment among 150 first-year college students. Employing correlational design, the statistical findings of the study reveal that the r coefficient of 0.59 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision (...) to reject the null hypothesis. Hence, a significant relationship exists between learning strategies, motivation, and the online learning environment. (shrink)

Contemporary genome editing techniques have made genomic intervention—from microorganism to human—more accessible, easier to use, and more accurate than previous methods. We argue that, notwithstanding its merits in treating and preventing disease in humans, genome editing represents a potential threat for domestic and international security, requiring an integrated approach in regulating, detecting, preventing, and mitigating the risk of its use for malicious purposes. Despite the global regulatory ambitions of the 2021 WHO framework, we see insufficient attention given to the future (...) prospect of dual-use genomic technology. Drawing parallels with the nuclear field, we suggest tentative practical steps for a way forward in dealing with genome editing technologies, such as: 1) adapting national (bio)security and defence strategies to include genome editing as a possible threat (with conceivable WMD potential); 2) enhancing the international dialogue on genome editing and raising the issue at the highest level; 3) working towards a global, legally binding verification mechanism; 4) tracking genome editing technologies.

Studies of non-standard, project-based forms of work prevalent in the creative industries have typically theorized the relational dynamics of work as a competitive process of social capital accumulation involving an individualistic, self-enterprising, zero-sum, and winner-takes-all struggle for favourable social network-positioning. Problematizing this prevailing conceptualization, our empirical case study draws on fifty in-depth interviews and two focus groups with creative workers in Ghana to show how relations of mutual aid, including elaborate efforts to live harmoniously with others, are intricately intertwined with (...) economic practices of getting by and getting ahead. Our analysis abductively mobilizes insights from Afro-communitarian ethics to theorize the mutual aid we observed as a complex socio-economic practice of relational resource redistribution contingent on degrees of social proximity. In applying “a theory from the South” to foreground the role of moral obligations, social harmony, and hands-on practices of mutual aid in non-standard forms of work, we contribute a “decolonial critique” of relationality of relevance to scholars of creative work and business ethicists.

Recent research has found that the omission of accent marks in Spanish does not produce slower word identification times in go/no-go lexical decision and semantic categorization tasks [e.g., cárcel = carcel], thus suggesting that vowels like á and a are represented by the same orthographic units during word recognition and reading. However, there is a discrepant finding with the yes/no lexical decision task, where the words with the omitted accent mark produced longer response times than the words with the accent (...) mark. In Experiment 1, we examined this discrepant finding by running a yes/no lexical decision experiment comparing the effects for words and non-words. Results showed slower response times for the words with omitted accent mark than for those with the accent mark present, thus suggesting a bias toward a “word” response for accented items in the yes/no lexical decision task. To test this interpretation, Experiment 2 used the same stimuli with a blocked design and a go/no-go lexical decision task. Results showed similar response times to words regardless of whether the accent mark was omitted. This pattern strongly suggests that the longer response times to words with an omitted accent mark in yes/no lexical decision experiments are a task-dependent effect rather than a genuine reading cost.

U radu se raspravlja o pojmu i povijesti utopije, pri čemu se naglasak stavlja na moderne oblike utopija rodne tematike. Iako bi se moglo reći da je utopijsko mišljenje imanentno čovjeku, danas se riječ ‘utopija’ koristi mahom u pejorativnom značenju tlapnje i/ili političke zamisli čije ostvarenje nužno vodi u neki oblik totalitarizma. Takva su određenja utopije iznikla iz etimoloških, povijesnih i idejnih nedoumica vezanih uz utopijske teorijske i praktične tvorevine. Opisujući utopiju pojmovima kritike, nade i mašte te ju vezujući uz (...) pojam Mannheimove aktivne utopije, u njoj je moguće pronaći elemente za suočavanje s modernim rodnim i ekološkim problemima. Kao primjer su dane feminističke utopije u kojima su testirane razne rodne teorije i prakse te su predložena rješenja za stvaranje ne idealnih i dovršenih, već poboljšanih svjetova, odnosno svjetova koji dopuštaju poboljšanje.This article discusses the concept and history of utopia with an emphasis on the modern forms of gender utopias. Although it can be said that utopian thought is inherent to humans, today the word ‘utopia’ is generally used in a pejorative meaning of an illusion and/or political concept whose actualization necessarily leads to some form of totalitarianism. These assumptions originated from etymological, historical and conceptional dilemmas associated with utopian theoretical and practical realizations. Describing utopia in terms of critique, hope and imagination as well as linking it with the concept of Mannheim’s active utopia it is possible to find in it elements that can be used for dealing with modern gender and ecological problems. As an example are given feminist utopias in which were tested different gender theories and practices and were suggested solutions for creating not ideal or completed but improved worlds, that is, worlds that allow improvement.

Extractive foraging tasks, such as digging, are broadly practiced among hunter-gatherer populations in different ecological conditions. Despite tuber-gathering tasks being widely practiced by children and adolescents, little research has focused on the physical traits associated with digging ability. Here, we assess how age and energetic expenditure affect the performance of this extractive task. Using an experimental approach, the energetic cost of digging to extract simulated tubers is evaluated in a sample of 40 urban children and adolescents of both sexes to (...) measure the intensity of the physical effort and the influence of several anatomical variables. Digging is a moderately vigorous activity for inexperienced girls and boys from 8 to 14 years old, and it requires significant physical effort depending on strength and body size. However, extracting subterranean resources is a task that may be performed effectively without previous training. Sex-specific and age-specific differences in the net energy expenditure of digging were detected, even though both sexes exhibited similar proficiency levels when performing the task. Our results highlight that both boys and girls spend considerable energy while digging, with differences largely driven by body size and age. Other factors beyond ability and experience, such as strength and body size, may influence the proficiency of juveniles in performing certain physically intensive foraging tasks, such as gathering tubers.

This review essay explores recent historical and anthropological literature on the emergence and development of transcultural psychiatry in the second half of the twentieth century. It examines how postcolonial psychiatry attempted to remove itself from its erstwhile colonial frameworks and strove to introduce new concepts and paradigms to make itself relevant in the context of decolonization and postwar reconstruction. The essay looks at both continuities and discontinuities between colonial and post-colonial transcultural psychiatry, asking how the recent surge of scholarly literature (...) in this field engaged with these issues. It also aims to identify the most important avenues for future research. (shrink)

Pretendemos analisar a crítica ao direito marxiana exposta nos comentários à obra Lectures on the early history of institutions, do jurista inglês Henry Sumner Maine, presentes nos "assim chamados" Cadernos Etnológicos. Para tal, passaremos pela crítica de Karl Marx à teoria do direito de Maine, passando também por considerações sobre os juristas analíticos John Austin e Jeremy Bentham, nos quais o autor das Lectures se baseia fortemente. Em seguida, trataremos das críticas à concepção de Maine sobre a origem do Estado (...) e do direito. Então, explicaremos como Marx se contrapõe a Maine voltando-se para o solo da história real, e assim analisa a gênese e o desenvolvimento direito na Irlanda e sua associação com a religião cristã, tanto antes quanto durante a colonização inglesa, observando também a violência por trás da imposição das leis coloniais.

Background Despite nurses receiving education on how to respond during crises, the stress and demands arising from unprecedented situations, such as the COVID-19 pandemic, may affect their work engagement. Aim To appraise and synthesize studies examining work engagement among nurses in the context of the COVID-19 pandemic. Methods It is a systematic review in which three databases were searched. Critical appraisal tools and PRISMA guidelines were used. Content analysis was performed. Ethical considerations Ethical approval was not required for this systematic (...) review. Findings A total of 21 studies were included. The results were classified into three categories: (1) levels and meanings of work engagement, (2) the relationship of work engagement with various factors, and (3) measures to enhance work engagement. Conclusion The review revealed that nurses’ work engagement varied from moderate to high. Factors such as education level and work schedule flexibility influenced their engagement. Positive associations were found between work engagement and job satisfaction, intention to stay, and organizational support, while stress and workload showed negative relationships. The crucial role of health policymakers, hospital administrators, and nurse managers in acting ethically, creating favorable working conditions and fostering nurses’ work engagement was emphasized.

Natural deduction systems for classical, intuitionistic and modal logics were deeply investigated by Prawitz [D. Prawitz, Natural Deduction: A Proof-theoretical Study, in: Stockholm Studies in Philosophy, vol. 3, Almqvist and Wiksell, Stockholm, 1965. Reprinted at: Dover Publications, Dover Books on Mathematics, 2006] from a proof-theoretical perspective. Prawitz proved weak normalization for classical logic only for a language without logical or, there exists and with a restricted application of reduction ad absurdum. Reduction steps related to logical or, there exists and classical (...) negation bring about many problems solved only rather recently. For classical S5 modal logic, Prawitz defined a normalizable system, but for a language without logical or, there exists, ◊ and, for a propositional language without ◊, Medeiros [M.da P.N. Medeiros, A new S4 classical modal logic in natural deduction, Journal of Symbolic Logic 71 799–809] presented a normalizable system for classical S4. We can mention many cut-free Gentzen systems for S4, S5 and K45/K45D, some normalizable natural deduction systems for intuitionistic modal logics and one more for full classical S4, but not for full classical S5. Here our focus is on the definition of a classical and normalizable natural deduction system for S5, taking not only □ and ◊ as primitive symbols, but also all connectives and quantifiers, including classical negation, disjunction and the existential quantifier. The normalization procedure is based on the strategy proposed by Massi [C.D.B. Massi, Provas de normalizaçaõ para a lógica clássica, Ph.D. Thesis, Departamento de Filosofia, UNICAMP, Campinas, 1990] and Pereira and Massi [L.C. Pereira, C.D.B. Massi, Normalização para a lógica clássica, in: O que nos faz pensar, Cadernos de Filosofia da PUC-RJ, vol. 2, 1990, pp. 49–53] for first-order classical logic to cope with the combined use of classical negation, disjunction and the existential quantifier. Here we extend such results to deal with □ and ◊ too. The elimination rule for ◊ uses the notions of connection and of essentially modal formulas already proposed by Prawitz for the introduction of □. Beyond weak normalization, we also prove the subformula property for full S5. (shrink)

O propósito desse artigo é apresentar o trabalho realizado por José Chasin na elucidação de um aspecto central do pensamento de Marx, que é a crítica à política. Não se trata só da conhecida questão do fim do Estado, uma vez que essa se coloca no interior de uma determinação mais ampla que é a da necessidade, da origem e do significado da política, reflexão desenvolvida por Marx, que conduz à consequente negação da politicidade enquanto atributo inerente à existência social, (...) aspecto que Chasin procura explicitar na obra do autor e que é fundamental para o resgate do sentido profundo da proposição marxiana, qual seja, a possibilidade da emancipação humana, desentranhada das ilusões sobre as quais se sustenta a concepção tradicional da política.

En este trabajo abordo un caso específico del problema clásico de la individuación en la Filosofía de la Biología: el de las colonias de insectos, y en particular, de hormigas. El carácter individual de un conjunto de hormigas que forman una colonia puede ser objeto de controversia, ya que, desde un punto de vista intuitivo, no parece constituir un individuo. Mi objetivo es demostrar que las colonias de hormigas son individuos biológicos. Para ello, me centro en dos de los tipos (...) de individuos más estudiados en la Filosofía de la Biología: los funcionales y los evolutivos, y examino si las colonias de hormigas cumplen con las condiciones necesarias para ser consideradas individuos en estos términos.

Este trabajo aborda el tema de la maternidad a través de algunos filmes y series de ficción que nos acercan a un mundo en el que dicha realidad se somete a juicio en sus aspectos más elementales. Nos situamos a principios del siglo xxi, en sociedades democráticas, en mayor o menor medida liberales y de raíz judeocristiana, en las que se están produciendo cambios y promoviendo debates que hacen tambalear las estructuras sociales y familiares tradicionales. En un contexto en el (...) que se han modificando los cauces a través de los cuales se ha ejercido siempre la maternidad, nos preguntamos si hablamos de algo inmutable, vinculado a la identidad femenina; o por el contrario, es una realidad mutable en su esencia, que debe adaptarse en sus formas a los cambios culturales y sociales de nuestro entorno. Para ver las respuestas que el cine nos ofrece acerca de estas cuestiones, hemos elegido una serie de películas rodadas desde 1999, que consideramos fundamentales para arrojar luz sobre el tema. Dichos filmes nos presentan modelos de mujer que se enfrentan a la maternidad desde distintas situaciones y diferentes enfoques, en entornos complejos y cambiantes, que invitan a una reflexión en torno a los fundamentos sobre los que se construye nuestra sociedad.

Este artigo centra-se na memória de António Ribeiro dos Santos e nas redes de sociabilidade do primeiro bibliotecário-mor da Real Biblioteca Pública da Corte. Na correspondência que mantém com outros sábios e eruditos, as regras de civilidade conjugam-se com o estilo de vida do académico e do bibliotecário. As redes de sociabilidade literária em que Ribeiro dos Santos se integra são nacionais e internacionais e não excluem a participação de mulheres cultas e eruditas. Relacionando alguns tópicos do debate de ideais (...) que Ribeiro dos Santos sustenta, em privado e em público, salientamos o carácter pioneiro das suas reflexões sobre a moderação de penas judiciais e a abolição parcial da pena de morte em Portugal. Esta questão, sendo indissociável das grandes mudanças culturais trazidas pelo século das Luzes, permite compatibilizar o legado do utilitarismo jurídico moderno com o racionalismo humanista católico.
