In order to involve children in the decision-making process about participation in medical research it is widely recommended that the child’s assent be sought in addition to parental consent. However, the concept of assent is fraught with difficulties, resulting in confusion among researchers and ethics committees alike.

We propose new definitions of explanation, using structural equations to model counterfactuals. The definition is based on the notion of actual cause, as defined and motivated in a companion article. Essentially, an explanation is a fact that is not known for certain but, if found to be true, would constitute an actual cause of the fact to be explained, regardless of the agent’s initial uncertainty. We show that the definition handles well a number of problematic examples from the literature.

We propose a new definition of actual causes, using structural equations to model counterfactuals. We show that the definition yields a plausible and elegant account of causation that handles well examples which have caused problems for other definitions and resolves major difficulties in the traditional account.

Community engagement is increasingly promoted as a marker of good, ethical practice in the context of international collaborative research in low-income countries. There is, however, no widely agreed definition of community engagement or of approaches adopted. Justifications given for its use also vary. Community engagement is, for example, variously seen to be of value in: the development of more effective and appropriate consent processes; improved understanding of the aims and forms of research; higher recruitment rates; the identification of important ethical (...) issues; the building of better relationships between the community and researchers; the obtaining of community permission to approach potential research participants; and, the provision of better health care. Despite these diverse and potentially competing claims made for the importance of community engagement, there is very little published evidence on effective models of engagement or their evaluation.

Emotion recognition skills and the ability to understand the mental states of others are crucial for normal social functioning. Conversely, delays and impairments in these processes can have a profound impact on capability to engage in, maintain, and effectively regulate social interactions. Therefore, this study aimed to compare the performance of 42 autistic children, 45 unaffected siblings, and 41 typically developing controls on the Affect Recognition and Theory of Mind subtests of the Developmental Neuropsychological Assessment Battery. There were no significant (...) differences between siblings and TD controls. Autistic children showed significantly poorer performance on AR when compared to TD controls and on TOM when compared to both TD controls and unaffected siblings. An additional comparison of ASD, unaffected sibling and TD control subsamples, matched on full-scale IQ, revealed no group differences for either AR or TOM. AR and TOM processes have received less research attention in siblings of autistic children and remain less well characterized. Therefore, despite limitations, findings reported here contribute to our growing understanding of AR and TOM abilities in siblings of autistic children and highlight important future research directions.

According to common judicial standard, judgment in favor ofplaintiff should be made if and only if it is more probable than not thatthe defendant''s action was the cause for the plaintiff''s damage (or death). This paper provides formal semantics, based on structural models ofcounterfactuals, for the probability that event x was a necessary orsufficient cause (or both) of another event y. The paper then explicates conditions under which the probability of necessary (or sufficient)causation can be learned from statistical data, and (...) shows how data fromboth experimental and nonexperimental studies can be combined to yieldinformation that neither study alone can provide. Finally, we show thatnecessity and sufficiency are two independent aspects of causation, andthat both should be invoked in the construction of causal explanations for specific scenarios. (shrink)

Much philosophical attention has been devoted to “The Land Ethic,” especially by Anglo-American philosophers, but little has been paid to A Sand County Almanac as a whole. Read through the lens of continental philosophy, A Sand County Almanac promulgates an evolutionary-ecological world view and effects a personal self- and a species-specific Self-transformation in its audience. It’s author, Aldo Leopold, realizes these aims through descriptive reflection that has something in common with phenomenology-although Leopold was by no stretch of the imagination a (...) phenomenologist. Consideration of human-animal intersubjectivity, thematized in A Sand County Almanac, brings to light the moral problem of hunting and killing animal subjects. Leopold does not confront that problem, but it is confronted and resolved by Jose Ortega y Gassett, Henry Beston, and Paul Shepard in terms of an appropriate human relationship with wild-animal Others. Comparison with the genuinely Other-based Leopold-Ortega-Beston-Shepard wild-animal ethic shows the purportedly Other-based humanand possibly animal ethic of Emmanuel Levinas actually to be Same-based after all.

Decision-making competence reflects individual differences in the susceptibility to decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate mechanisms that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC) and one such mechanism, (...) the degree to which individuals make choices consistent with maximizing expected value (EV). Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a) choosing risky options when expected value favors those options and (b) avoiding risky options when expected value favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

This 1945 “Preface” is intended to answer the question “What is phenomenology?” and to justify it as the methodology of the long work of philosophical psychology to follow. Merleau-Ponty approaches this task by first setting out the apparent paradoxes and contradictory claims that have been advanced by phenomenology, in a long and eloquent survey section that is built on a series of “X, but also Y” rhetorical devices. He then surveys four prominent themes of phenomenology. Just as he does in (...) the introductory section of the essay “The Philosopher and His Shadow,” Merleau-Ponty here presents himself as the chief interpreter and champion of Husserl's later philosophy. The first major theme considered is that phenomenology is a matter of describing the field of perception. This sets it in contrast to the prevalent explanatory methodologies of a) scientific empiricism and b) metaphysical idealism. Empirical science (such as mathematical physics) begins with observation, but then abstracts entirely from lived experience to consider idealized schematic cases (such as motion across a frictionless surface) that may reveal universal laws. Such a methodology is obviously fruitful in important respects, but is nonetheless naïve and dishonest in its renunciation of the specifics of observed events. The metaphysical idealism of Kant or Descartes likewise abstracts from the experienced particularity of perception to posit an “inner man” that constitutes the world according to 2 internal, transcendental principles. Merleau-Ponty's criticism is the same, whether these principles are “reason” of Rationalism, “the categories of understanding” of Critical Rationalism, or the rules governing the “association of ideas” posited by Empiricism. Phenomenology indicates that perception is not an act but a fact; the world is not an object but rather the unified setting of perception; and the inner man is a myth, along with his allegedly privileged access to univocal truth. The second theme is the technique of “phenomenological reduction,” the suspension of belief in the assemblage of everyday assumptions known as the “natural attitude.” Husserl's understanding of the reduction long led him to an idealist position: that all particular consciousnesses are united in a transcendental ego..

Qaside-i Khamriyya (meaning Wine Eulogy) of sufi poet Ibn-i Fārıḍ, in which he explained divine love through the metaphor of wine, attracted great attention in Islamic world and was translated into Arabic, Persian and Turkish. Scholars such as Davud-i Qayseri (d. 751 AH/1350 AD), Kemal Pashazāde (d. 940 AH/1534 AD), Abdulghani an-Nablusi (d. 1143 AH/1731 AD), Ibn Acibe (d. 1224 AH/1809 AD) explained this eulogy in Arabic, while poets such as Ali b. Shihābiddin al-Hamadāni (d. 786 AH/1385 AD), Molla Cāmi (...) (d. 898 AH/1492 AD), Idris-i Bitlisi (d. 926 AH/1520 AD) wrote commentaries in Persian. On the other hand, authors such as Abdussalam b. Numan b. Khalil (d. 1000 AH/1592 AD [?]), Ismail Anqaravi (d. 1041 AH/1631 AD), Abdulmacid-i Sivasi (d. 1049 AH/1639 AD), Qara Musṭafa Khulūsi (d. 1344 AH/1926 AD), Meḥmed Naẓım (d. 1345 AH/1926 AD) and Ṭahir al-Mavlavi (d. 1371 AH/1951 AD) translated the eulogy into Turkish. One of the authors who translators of this eulogy was Mehmed Said Efendi, sheikh of Uskudar Salimiya Takka, who lived in the 19th century. His work named Ṭarab-angiz (meaning Pleasure-provoking) is a condensed commentary with ornate prose of Qaside-i Khamriyya. In previous studies, Ṭarab-angiz was partly examined, and there was no mention about the identity and personality of the author. In the present research, the life and personality of Meḥmed Said Efendi is explained and the text of his work is examined.Summary: In Turkish literature which developed under the influence of Islam, translations and commentaries have important a place along with original texts. Coming within the sphere of Islam in early 10th century, Turks embarked on translating the texts immediately in order to learn their new religion and to perform its practices and continued to do so since then. Because they lived in the same culture and civilization climate, Turks learned Islam from Persians and were influenced by Persian language. However, adherents of this new religion also made direct translations from Arabic texts. The translations initially were made from religious works, but in time social, cultural and literary works, such as Persian classics and major eulogies of Arabic Literature, were also translated into Turkish by Turkish scholars. Qaside-i Burde by Ka‘b b. Zuheyr’in (d. 24 AH/645 AD), Qaside-i Nūniyye by Ebu’l-Fetḥ Busti’nin (d. 400 AH/1010 AD), Qaside-i Ṭanṭarāniyye by Ṭanṭarāni’nin (d. 485 AH/1092 AD), Qaside-i Münferice by Ibnu’n-Naḥvi’nin (d. 513 AH/1119 AD), Qaside-i Emāli by Ali b. Othman al-Ushi’nin (d. 575 AH/1179 AD) and famous eulogy named Qaside-i Bur’e by Muḥammed b. Said al-Buṣiri’nin (d. 695 AH/1296 AD) were among such works.Qaside-i Khamriyya by sufi poet Ibn-i Fārıḍ (d. 632 AH/1235 AD), also called sultan of minstrels, in which he explained divine love through wine attracted great attention in Islamic world and was translated into many languages and many commentaries were written on it. One of the commentary writers about this eulogy is Meḥmed Said Efendi, a 19th century sufi. His work entitled Ṭarab-angiz is a condensed commentary with ornate prose of Qaside-i Khamriyya.Studies conducted so far has partly dealt with the Ṭarab-angiz and identity and personality of Meḥmed Said Efendi have never been mentioned. Ṣarac mentioned, “It is a printed work but its writer, printing date, and the place was not found on the printed work”, while Yıldırım used the expression of “a work whose writer and production date is not known.” In his Ph. D. thesis entitled Translation and Commentary Tradition in Classical Turkish Literature in Anatolia, Ṣadık Yazar noted that the work belongs to Meḥmed Said, which was later cited by Aqdag. The final statement on this issue was made by İnce in his work entitled Arabic, Persian and Turkish commentaries of Qaside-i Khamriyya by Ibnu’l Fārıḍ. He examined a total of 18 commentaries and stated that no information is available about the life of Meḥmed Said although he mentioned Ṭarab-angiz.The birth date and place of Meḥmed Said Efendi are unknown. He is grandchild of Ali Behjet Efendi (d. 1238 AH/1823 AD), one of sheiks in Salimiya Dervish Lodge in Uskudar and son of Meḥmed Hidāyetullah Efendi (d. 1288 AH/1871 AD). Following the death of his father, Meḥmed Said Efendi himself served as the head dervish of this dervish lodge for 25 years and became a famous figure. He died in 1313 AH/1896 AD and was buried in the cemetery of the Salimiya Dervish Lodge.Meḥmed Said Efendi was the sixth sheikh of Salimiya Dervish Lodge. In many sources, he was mentioned as a venerable, righteous, devoutly religious, virtuous, polite and scholarly man. Meḥmed Said Efendi is thought to be a member of Mavlavi lodge of Naqshbandi Ṭariqa. He had successors such as Naqshi sheikh Uskudari Balabani Ḥasan Ḥusnu Efendi (d. 1347 AH/1928 AD) and Ismail Efendi (d. after 1307 AH/1890 AD). The poet had a commentary named Ṭarab-angiz in prose form and had a quatrain within the praising eulogy of Sheikh Ḥāmil Efendi (d. 1322 AH/1904 AD), head sheikh of Beylerbeyi Bedevi Dervish Lodge.It is clear from the expression, “A work by Meḥmed Said, the Imam of Central Dervish Lodge of Sultan Salim III,” at the beginning of Edition no: 450 in Suleymaniye Library, Pertev Pasha Collection and from the record of “Work: Ṭarab-angiz, Author: Ibnu’l-Fārıḍ, Translator and postscript writer: Meḥmed Said” in Edition no: 7350 of Marmara University Faculty of Theology Library that this work belongs to Sheikh Meḥmed Said Efendi. However, exact production date of this printed work is not known. The work consisted of 28 pages and in some editions a two-page correct-false chart was added.As usual, the work starts with an introduction section with expressions of “By the name of God, the Most Gracious, the Most Merciful,” “Praise be to God,” and “Peace be upon Prophet Moḥammad.” This section also includes a praise for followers of Prophet Moḥammad, “Who made sphere of prophecy an eternal rose garden through the holy light of their enjoyed manners in addition to making the Shari’a candle shined and and converting them to great flowers of service with their strong inspiration torchs.” The commentator then embarked on praising Qaside-i Khamriyya, mentioning that the men of ability became helpless in explaination of beauty, charm and freshness of unique expression richness and refined allegory blossoms of the eulogy and that reaching the shore of rhetoric could be possible through diving into the guided wisdom of sea. In fact, according to commentator, the men of literature should be aware of the difficulty of translating this unique eulogy into Turkish language. However, everyone should dive into the sea of insight as a knowledge diver, collect its share in pearls of utterance and in emeralds of wits, arrange and put them in the string of prose”. Therefore, he wrote the commentary about the eulogy as a service to humanity and as a contribution to his own stock of comfort in the present and afterlife as much as he could, no matter how little it could be, and named it Ṭarab-angiz. Like most commentators of Qaside-i Khamriyya, Meḥmed Said Efendi commented on only about 33 couplets of the eulogy which contained a total of 41 couplets, and did not cover couplets from 23 to 30 in his work. The commentator used couplet-by- couplet translation method and started with praising for Ibn-i Fārıḍ and his couplets. Then, he gives the Arabic originals of the couplets and starts commentary with the expressions such as “couplets of great intuition, imagery couplets, product of couplet, enlightenment of couplet and concept of couplet.” In preface section of the work, the commentator, who usually quoted hadith texts in Arabic and poems, does not use them in his commentary. He only uses some lines of Arabic prayers and a quatrain of Molla Cāmi (d. 898 AH/1492 AD). This is a quatrain rubāi in Persian language meaning that “If you want no sorrow and no grief of the destiny, drink wine in a pub, because swirling of the goblet and worries of the world do not share the same place just as the tune and the sorrow do not coincide.” The lack of touching on the meaning of words, etymological structure and grammar rules in couplets makes it different from others, except the translation of Aḥmed Ṣāfi Bey.

Judea Pearl (2000) was the first to propose a definition of actual causation using causal models. A number of authors have suggested that an adequate account of actual causation must appeal not only to causal structure but also to considerations of normality. In Halpern and Hitchcock (2011), we offer a definition of actual causation using extended causal models, which include information about both causal structure and normality. Extended causal models are potentially very complex. In this study, we show how (...) it is possible to achieve a compact representation of extended causal models. (shrink)

En 2002, Daniel Pearl, periodista del Wall Street Journal, era secuestrado y degollado ante una cámara. La grabación del degüello, con abierta intencionalidad pública, fue finalmente censurada por la inmensa mayoría de medios de comunicación occidentales y no trascendió el ámbito privado en el que se realizó. Las vejaciones y torturas fotografiadas en Abu Ghraib, en cambio, trascendieron en 2004 su inicial privacidad al ser publicadas por The New Yorker y la CBS, invadiendo así el espacio de lo público. (...) ¿Qué distingue ambas imágenes, determinando su «publicabilidad»? El presente artículo pretende analizar la censura de imágenes especialmente cruentas en los espacios informativos ¿i.e., al margen de los publicitarios o los de entretenimiento. Para ello, trataré de responder, en relación a este tipo de imágenes, a las siguientes preguntas: ¿Qué pueden mostrar? ¿Se deben mostrar? Y ¿cómo se deben mostrar? La primera pregunta se dirige a una cuestión estrictamente epistemológica. Dada su excesiva amplitud, me limitaré a establecer, por una parte, que es necesario defender una cierta idea de la verdad como correspondencia para poder distinguir entre imágenes verdaderas e imágenes falsas. Y, por otra parte, precisaré en qué podría consistir la falsedad de una imagen. Las dos segundas, en cambio, son de tipo ético y apuntan a la problemática formulación de una libertad de expresión relativa a las imágenes violentas. Trataré de poner de relieve la función decisiva de este tipo de imágenes como revulsivo y desarrollaré críticamente algunos de los argumentos habitualmente esgrimidos para impedir su difusión. Pretendo defender que, incluso si aceptamos que prima facie se debe poder ver todo, el centro del debate se halla en las condiciones de publicación y, principalmente, en la posible espectacularización mediática de las imágenes.

One of the most beautiful and enigmatic texts in the corpus of the Apocryphal Acts of the Apostles is beyond doubt the so-called Hymn of the Pearl, whose meaning, however, is far from getting an academic consensus in the current bibliography. As A.F.J. Klijn in his «The So-Called Hymn of the Pearl », Vigiliae Christianae, vol. 14, n. 3 156, stated a coherent analysis of the poem should bring an answer to two main questions: «What is meant with (...) the pearl? and Who is the principal person in this hymn?». The following pages will try to propose a tenable meaning to this passage by allocating it in its due conceptual context and will offer a consequent hypothesis to those questions that remain still opened.

Pearl opened the door to formally defining actual causation using causal models. His approach rests on two strategies: first, capturing the widespread intuition that X = x causes Y = y iff X = x is a Necessary Element of a Sufficient Set for Y = y, and second, showing that his definition gives intuitive answers on a wide set of problem cases. This inspired dozens of variations of his definition of actual causation, the most prominent of which are (...) due to Halpern & Pearl. Yet all of them ignore Pearl’s first strategy, and the second strategy taken by itself is unable to deliver a consensus. This paper offers a way out by going back to the first strategy: it offers six formal definitions of causal sufficiency and two interpretations of necessity. Combining the two gives twelve new definitions of actual causation. Several interesting results about these definitions and their relation to the various Halpern & Pearl definitions are presented. Afterwards the second strategy is evaluated as well. In order to maximize neutrality, the paper relies mostly on the examples and intuitions of Halpern & Pearl. One definition comes out as being superior to all others, and is therefore suggested as a new definition of actual causation. (shrink)

The present study aims to elucidate whether insight problem solving could be facilitated by the cognitive component of humour. The authors take interest in whether the logical mechanisms of humour can affect how fast insight problems are solved. To that end, the authors conducted two experiments where participants solved insight problems after watching visual humorous stimuli such as videos and slideshows. The first experiment demonstrated the overall impact of facilitation by humour on insight problem solving; however, it did not show (...) any difference in how particular logical mechanisms of humour affect the solution time of insight problems. The second experiment showed that the cognitive component of humour could selectively affect insight problems whose difficulty stems from different sources. These results suggest that the cognitive component of humour, when operationalised as logical mechanisms and schema switching, contributes to solving insight problems. (shrink)

S There is a long tradition of representing causal relationships by directed acyclic graphs (Wright, 1934 ). Spirtes ( 1994), Spirtes et al. ( 1993) and Pearl & Verma ( 1991) describe procedures for inferring the presence or absence of causal arrows in the graph even if there might be unobserved confounding variables, and/or an unknown time order, and that under weak conditions, for certain combinations of directed acyclic graphs and probability distributions, are asymptotically, in sample size, consistent. These (...) results are surprising since they seem to contradict the standard statistical wisdom that consistent estimators of causal effects do not exist for nonrandomised studies if there are potentially unobserved confounding variables. We resolve the apparent incompatibility of these views by closely examining the asymptotic properties of these causal inference procedures. We show that the asymptotically consistent procedures are ‘pointwise consistent’, but ‘uniformly consistent’ tests do not exist. Thus, no finite sample size can ever be guaranteed to approximate the asymptotic results. We also show the nonexistence of valid, consistent confidence intervals for causal effects and the nonexistence of uniformly consistent point estimators. Our results make no assumption about the form of the tests or estimators. In particular, the tests could be classical independence tests, they could be Bayes tests or they could be tests based on scoring methods such as  or . The implications of our results for observational studies are controversial and are discussed briefly in the last section of the paper. The results hinge on the following fact: it is possible to find, for each sample size n, distributions P and Q such that P and Q are empirically indistinguishable and yet P and Q correspond to different causal effects.

Increasingly there are calls for climate services to be “co-produced” with users, taking into account not only the basic information needs of users but also their value systems and decision contexts. What does this mean in practice? One way that user values can be incorporated into climate services is in the management of inductive risk. This involves understanding which errors in climate service products would have particularly negative consequences from the users’ perspective (e.g., underestimating rather than overestimating the change in (...) an impact variable) and then prioritizing the avoidance of those errors. This essay shows how inductive risk could be managed in climate services in ways that serve user values and argues that there are both ethical and practical reasons in favor of doing so. (shrink)

Background: Although ethics consultation has been introduced to clinical practice for many years, the results of empirical studies to evaluate the effectiveness of ethics consultation are still controversial. The design of randomised controlled trials is considered the best research design to evaluate the effect of a clinical practice on the outcomes of interests. In order to understand the effects of ethics consultation, we conducted this search for studies with the design of randomised controlled trials to evaluate ethics consultation.Objective: To provide (...) an integrated review of studies with the design of randomised controlled trials to evaluate the effectiveness of ethics consultation.Methods: PubMed was used to search for studies using the randomised controlled trial design to evaluate the effectiveness of ethics consultation. The search term used was “ethics consultation”. The selection criterion was limited to “randomised controlled trial”.Results: Four articles that met both search criteria were retrieved. One of these articles reported a study that did not actually use the design of a randomised controlled trial and is excluded from the following discussion.Conclusions: To apply randomised controlled trials to evaluate the effectiveness of ethics consultation is extremely difficult as long as two issues are not resolved: the standardisation of ethics consultation and a placebo for ethics consultation to eliminate the placebo effect. Thus, the results generated by the design of randomised controlled trials are always problematic. Furthermore, as long as the two issues exist, the results generated by the design of quantitative research methods always pose problems. (shrink)

El Festival Flores de la Diáspora Africana surge en 1999 en Costa Rica, organizado por la Fundación Arte y Cultura para el Desarrollo, con el propósito de promover las manifestaciones artísticas y culturales de la población afrocostarricense en particular, y de los pueblos afrodescendientes y africanos, de manera general. A lo largo de diecinueve ediciones, se ha colocado la cultura de matriz africana en el más alto nivel, con la presencia de grupos de ballet folclórico como el Kilandukilu de Angola, (...) el Ballet Garífuna de Honduras, la bailarina Bethania Nascimento, perteneciente al Alvin Hailey Ballet, y el Opus Dance Theater de New York. En el bel canto, la soprano Sarah Carrere, dio fe de su gran talento franco-senegalés, así como en gospel el coro de la iglesia St. Agustine de Washington, y grupos como Master Key, Charleene Stuart y Sasha Campbell, de Costa Rica, conquistaron la audiencia con ritmos como gospel, spiritual, R&B y Soul, sin olvidar las agrupaciones nacionales de Calipso, que han dejado su huella en el Festival.En esa pasión por mostrar los mejores representantes de las diferentes manifestaciones del arte y la cultura de la Diáspora Africana, en 2012 la Fundación invitó a Costa Rica al Premio Nobel de Literatura de 1984, Derek Walcott. Para dar continuidad a este trabajo con los artífices de la palabra, también en 2013 se realizó el 1er Encuentro de Escritores y Poetas Afrodescendientes, Indígenas y Sinodescendientes, cuyo resultado fue la antología: Tenemos la Palabra, en la cual se muestra el trabajo de casi cincuenta creadores.

Cheating is a serious issue among business students worldwide. However, research investigating the social factors that may help prevent cheating in Chinese higher education is rare. The present study examined two key social relationship factors of perceived teacher-student relationships and peer relationships by the students. It attempted to build a model which addressed the effects of two variables on Chinese business students’ cheating behaviour: the teacher’s approachability and the relationship goal of the students. Two important social influence factors were also (...) tested as mediators: neutralizing attitudes and perceived cheating norms of the students. A student survey was conducted with 1329 questionnaires collected. The results showed the negative effects of both social relationship variables on cheating, and that their effects were fully mediated by neutralizing attitudes. Moreover, perceived cheating norms fully mediated the effect of the teacher’s approachability, but not so for the relationship goal of the students. This study provided novel insights and recommendations for promoting academic integrity in Chinese business schools and universities. (shrink)

ABSTRACT Refugees crossing the Mediterranean Sea in small boats has become a common sight in the media, particularly since the so-called ‘refugee crisis’ in 2015. The number of boats crossing the English Channel between the French and UK coasts has been increasing as other migration routes have been closed down. This article reports the findings of a discourse analysis of 96 UK newspaper articles published in December 2018 when the daily crossings were referred to as a ‘major crisis’. Adopting a (...) broadly critical discursive psychology perspective, we identify the use of three main interpretative repertoires used within the media reporting. Firstly, a ‘secure the borders’ repertoire which positions the UK’s borders as porous and easily breached, secondly, a ‘smuggling is immoral’ repertoire which works to position smugglers as to blame for the current ‘crisis’ and removes responsibility for the crisis from the Government, and finally, a ‘desperate people’ repertoire which worked to position the refugees themselves as vulnerable and in need of protection, but also as people who will engage in risky behaviours. We suggest that the use of these repertoires ultimately functions to obscure the need for safe and legal migration routes to the UK. (shrink)

Graphical models are a powerful tool for causal model specification. Besides allowing for a hierarchical representation of variable interactions, they do not require any a priori specification of the functional dependence between variables. The construction of such graphs hence often relies on the mere testing of whether or not model variables are marginally or conditionally independent. The identification of causal relationships then solely requires some general assumptions on the relation between stochastic and causal independence, such as the Causal Markov Condition (...) and the Faithfulness Condition (Spirtes et al. 2000; Pearl 2000). However, a procedure would require further assumptions to hold. Namely those the independence tests themselves are based on. In continuous settings, Spirtes et al. (2000) suggest causal inference based on a very restrictive formulation of independence, that is, vanishing partial correlations. Such a measure does, however, limit the applicability of causal inference to linear systems. This constitutes a serious drawback especially for the social sciences where an a priori specification of the functional form proves difficult or at odds with linearity. In short: graphical models theoretically reduce specification uncertainty regarding functional dependence, but their implementation in practice deprives them of this virtue. In this paper we investigate how causal structures in continuous settings can be identified when both functional forms and probability distributions of the variables remain unspecified. We focus on tests exploiting the fact that if X and Y are conditionally independent given a set of variables Z, the two conditional densities f (X|Y, Z) and f (X|Z) must coincide. We start by estimating the conditional densities f(X|Y, Z) and f(X|Z) via nonparametric techniques (kernel methods). We proceed by testing if some metric expressing the distance between these very conditional densities is sufficiently close to zero. Out of several metrics available in the literature to express such distance we choose two, the Euclidean, and the Hellinger distance. We investigate in a Monte Carlo study how different tests involving either measure are able to detect statistical independence, conditioned on a small set of variables. One limitation may result from nonparametric density estimation being subject to the curse of dimensionality. As the number of variables increases, the estimated empirical density converges at a slower rate to its population value. To compensate this drawback we use a local bootstrap procedure which consists of resampling the data for each test. While local bootstrap strongly increases the computational time of the test, it succeeds in counterbalancing the curse of dimensionality. (shrink)

Following Henkin’s discovery of partially-ordered (branching) quantification (POQ) with standard quantifiers in 1959, philosophers of language have attempted to extend his definition to POQ with generalized quantifiers. In this paper I propose a general definition of POQ with 1-place generalized quantifiers of the simplest kind: namely, predicative, or “cardinality” quantifiers, e.g., “most”, “few”, “finitely many”, “exactly α ”, where α is any cardinal, etc. The definition is obtained in a series of generalizations, extending the original, Henkin definition first to a (...) general definition of monotone-increasing (M↑) POQ and then to a general definition of generalized POQ, regardless of monotonicity. The extension is based on (i) Barwise’s 1979 analysis of the basic case of M↑ POQ and (ii) my 1990 analysis of the basic case of generalized POQ. POQ is a non-compositional 1st-order structure, hence the problem of extending the definition of the basic case to a general definition is not trivial. The paper concludes with a sample of applications to natural and mathematical languages. (shrink)

'This study is extremely authoritative and up-to-date... This book has much to offer linguists motivated by any one of several primary interests, particularly universals and the connection between language and cognition' -Journal of Linguistics 'Aikhenvald displays the rare gift of being able to inspire interest in new research through the success of her own results, without stifling those future possibilities through undue certitude in having discovered all of the answers already. The best thing about this very excellent book is precisely (...) the author's keen awareness that it is not the last word on the subject' -Journal of Linguistics 'Data presented in a clear, straightforward manner... also cutting edge research presented in the spirit of a work in progress' -Journal of LinguisticsAlmost all languages have some ways of categorizing nouns. Languages of South-East Asia have classifiers used with numerals, while most Indo-European languages have two or three genders. They can have a similar meaning and one can develop from the other. This book provides a comprehensive and original analysis of noun categorization devices all over the world. It will interest typologists, those working in the fields of morphosyntactic variation and lexical semantics, as well as anthropologists and all other scholars interested in the mechanisms of human cognition.
