It has been suggested that hierarchically structured symbols, a remarkable feature of human language, are produced via the operation of recursive combination. Recursive combination is frequently observed in human behavior, not only in language but also in action sequences, mind-reading, technology, et cetera.; in contrast, it is rarely observed in animals. Why is it that only humans use this operation? What is the adaptability of recursive combination? We aim (1) to identify the environmental feature(s) in which recursive combination is effective (...) for survival and reproduction, and that has facilitated the evolution of this ability, and (2) to demonstrate the possible evolutionary processes of recursive combination. To achieve this, we constructed an evolutionary simulation of agents that generated products using recursive combination and used the results to explore the types of fitness functions (that reflect the kinds of adaptive environments) that give rise to this ability. We identified two types of adaptability of the recursive combination: (1) diversifiability of production and (2) diversifiability of products. Through the former, recursive combination promotes robustness against failure of production caused by inaccurate manipulations or irreversible changes. In an environment in which diversified products are preferable, sharing a portion of the production process for these products entails producing multiple products in which recursive combination plays a key role. We suppose that recursive combination works as a driving force of material culture. Finally, we discuss the possible evolutionary scenarios of recursive combination that is later generalized to encompass many aspects of human cognition, including human language. (shrink)

Specificities of enzymes involved in plant specialized metabolism, including flavonoid biosynthesis, are generally promiscuous. This enzyme promiscuity has served as an evolutionary basis for new enzyme functions and metabolic pathways in land plants adapting to environmental challenges. This phenomenon may lead, however, to inefficiency in specialized metabolism and adversely affect metabolite‐mediated plant survival. How plants manage enzyme promiscuity for efficient specialized metabolism is, thus, an open question. Recent studies of flavonoid biosynthesis addressing this issue have revealed a conserved strategy, namely, (...) a homolog of chalcone isomerase with no catalytic activity binds to chalcone synthase, a key flavonoid pathway enzyme, to narrow (or rectify) the enzyme's highly promiscuous product specificity. Reducing promiscuity via specific protein–protein interactions among metabolic enzymes and proteins may be a solution adopted by land plants to achieve efficient operation of specialized metabolism, while the intrinsic promiscuity of enzymes has likely been retained incidentally.

現代を生き抜くための武器としての哲学を、西野カナ、ミスチル、いきものがかり等Jポップの歌詞を題材に、気鋭の哲学者が説く。.

Globalization has changed the nature of business in the twenty-first century :481–502, 2010). With the increased internationalization of multinational corporations, the need to address international marketing ethics arises :481–493, 2005). Given the diversity of environments and cultures, ethical issues are numerous and complicated :3–24, 2001). The understanding of international marketing ethics is critical to academics as well as practitioners. This paper is a literature review of the study of ethics in international marketing. In order to develop a comprehensive review of (...) articles, we review topics such as ethical problems, moral philosophies, and culture and ethics. We also discuss the methodological procedures that are used in international marketing ethics. Researchers and practitioners alike can use this research on international marketing ethics to discuss the phenomena and subsequently lead to future work research. (shrink)

Este artículo pretende analizar tanto el nombramiento como el cese de los cadíes desde el punto de vista de sus cualificaciones académicas. Se centra en la práctica del cadiazgo en Egipto durante el período ‛abbāsí. Las fuentes principales son los Ajbār al-quḍāt de Wakī' y el Kitāb wulāt Miṣr de al-Kindī. Ambas obras contienen material de una gran originalidad y son bastante completas, ofreciendo detallada información sobre temas relativos tanto al nombramiento como al cese de los jueces durante los primeros (...) siglos de la historia islámica de Egipto. Se estudia la biografía de cada juez para averiguar cuáles fueron las razones que determinaron su nombramiento y su cese. Los resultados obtenidos son de interés para comprender las prácticas judiciales y su relación con las aptitudes profesionales que se consideraban necesarias en aquella época. (shrink)

Identifying the expression of anger in a foreign language and reproducing it appropriately and precisely are skills whose relevance and lack of satisfying proposals have been pointed by research on the pedagogy of emotions (Dewaele, 2010; Toya & Kodis, 1996). This paper combines an identification of lacks in the pedagogy of emotional intonation with an analysis of spontaneous samples of anger as a basis to didactic guidelines for the introduction of the contextualized teaching of anger expression in Spanish. Through (...) colloquial samples, key features for the expression of anger in Spanish are identified. A selection of technical features is adapted in an accessible didactic proposal that is conformed of the stages of identification, induction of recurrent patterns, guided and free production. The proposal offered here is a starting point for the design of didactic units on emotional and expressive speech, an area that lacks didactic guidelines. (shrink)

Los estudios modernos sobre derecho islámico han puesto de relieve la necesidad de estudiar los procedimientos jurídicos en el Islam y el papel desempeñado por la práctica judicial en su formación. Se considera en general que, en el período temprano, los cadíes disponían de mayor libertad en lo relativo a testigos y métodos para establecer pruebas. Posteriormente y de forma gradual el sistema se volvió más rígido y restrictivo. En relación a este desarrollo, los investigadores han propuesto distintas fechas, que (...) van desde la segunda mitad del siglo VII hasta el siglo VIII e incluso hasta el siglo XI. Estos investigadores han tratado la doctrina de al-yamīn ma‛ al-šàhid como una excepción dentro del procedimiento establecido por la šarī‛a que, según ellos, se basaba estricta y mecánicamente en la doctrina de los dos testigos. Para dichos investigadores, la doctrina de al-yamīn ma‛ al-šàhid surgió bajo la influencia de determinadas locadidades o bien por influencia judía. Este artículo propone que esa doctrina debió de surgir en el contexto del período de la guerra civil, cuando las cuestiones sobre qiṣāṣ, qawad, qasāma y ḥakam fueron discutidas con frecuencia en relación con el Corán y la sunna común y cuando se sintió la necesidad de reformar la institución del ḥakam. Sobre la base de afirmaciones dispersas de ulemas que vivieron en fechas cercanas a ese período, afirmaciones que se ven confirmadas por los comentarios de Wakī‛, se concluye que Mu‛āwiya fue quien introdujo ese método para reformar la institución del ḥakam. La práctica judicial de esta doctrina también confirma que estaba demasiado difundida como para poder considerarla una práctica medinense o una práctica local, tal y como pretenden algunos juristas clásicos, los tradicionistas y algunos investigadores modernos.

There are diverse pathways to becoming an academic, yet personal histories of successful academics who have taken non-traditional routes often remain undocumented. This qualitative and autobiographical study is guided by the theories of equifinality and career construction (von Bertalanffy, 1968; Toya, 2020; Savickas, 2005), aiming at filling this gap by documenting a personal journey from classroom teaching to academia. The study findings reveal that career pathways are marked by significant milestones, challenges and strategic decision-making processes that shape the career (...) trajectory. The results underscore the validity of equifinality in academic career development and active role individuals play in constructing their career narratives. It is recommended that institutions and policymakers in higher learning institutions should recognize and value non-traditional career paths as valuable assets within individuals’ career development.
