SummaryThis paper analyses the development of three methods for detecting bloodstains during the first half of the nineteenth-century in France. After dealing with the main problems in detecting bloodstains, the paper describes the chemical tests introduced in the mid-1820s. Then the first uses of the microscope in the detection of bloodstains around 1827 are discussed. The most controversial method is then examined, the smell test introduced by Jean-Pierre Barruel in 1829, and the debates which took place in French academies and (...) learned societies during ensuing years are surveyed. Moving to the courtrooms a review is conducted of how the different methods were employed in criminal trials. By reviewing these cases, the main arguments against Barruel's test during the 1830s are explored as well as the changes making possible the return of the microscope to legal medicine around 1840. By reconstructing the history of these three methods, the paper reveals how the senses of smell and vision were employed in order to produce convincing evidence in both academies and courts. The paper questions two linear master narratives that are organized in terms of progress and decline: the development of forensic science as a result of continued technological progress; and the supposed decline of smell in the history of the senses, particularly in the realm of chemistry and medicine.

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

The focus of this work is the analysis of changes in completed family size and possible determinants of that size over time, in an attempt to characterize the evolution of reproductive patterns during the demographic transition. With this purpose in mind, time trends are studied in relation to the mean number of live births per family (as an indirect measure of fertility), using family reconstitution techniques to trace the reproductive history of each married woman. The population surveyed is a Spanish (...) rural community called Lanciego, located at the southern end of the province of Alava (Basque Country). A total of 24,510 parish records of baptisms, marriages and burials made between 1800 and 1969 were examined to obtain the demographic data set. For each reconstituted family, the variables included in the study were the number of live births per family or family size (FAMS), year of marriage (YEAR), age at marriage of both partners (AMAN, AWOM), wife’s age at the end of marriage (WEND), duration of marriage (MARD), age at first maternity (A1CH), length of reproductive span (REPS) and number of children dying before their first anniversary (MINF). Through a principal component analysis, three factors were found that explained more than 75% of the total variance. Association of variables in factors I and III was particularly useful in characterizing the variability of mean family size in pre-transitional, transitional and post-transitional cohorts. During demographic transition, a decreasing trend is observed in the variables FAMS, REPS and MINF, while variables AWOM, AMAN, WEND and A1CH show a tendency to increase over the 20th century. Results obtained by multiple regression analysis confirm that the best predictors of family size (dependent variable) were REPS and MINF, which between them explained over 85% of the total variation in FAMS (R2=0·853). In Lanciego, birth control seems to be present on the evidence of an increase in age at first maternity and a decrease in age at last parturition, indicating that the beginning of the reproductive span is delayed and its end is brought forward. Interaction between family size and infant mortality is discussed in the light of various hypotheses, including replacement of descendants, the so-called biological effect and the theory of r and k selection.

In today's world, the corporate image of the largest companies is closely linked to their performance in the field of corporate social responsibility and the disclosure of information on that topic, specifically, on climate change. Since the Board of Directors is the body responsible for this process, the aim of this article is to show the role that companies' Boards of Directors play in the accountability process vis-à-vis stakeholders in relation to one specific aspect which has enormous significance in environmental (...) information: practices used to monitor greenhouse gas emissions. In order to achieve this, we shall verify certain business characteristics, in addition to the size and activity of the Board of Directors, and we shall take different dependence models into consideration. These models will include variables related to the level of independence and diversity of the Board of Directors, which interact with dummy variables representing the company's litigation risks regarding environmental behavior and the institutional macro-context of the organization's country of origin. The results make it clear that Boards of Directors are basically focused on the traditional responsibility of creating economic value, instead of dealing with today's broader business world concepts, which include social responsibility. This focus, therefore, does not favor the accountability process before other stakeholders, if this makes it more difficult to protect the interests of shareholders. (shrink)

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19.

In lieu of an abstract, here is a brief excerpt of the content:Hume and Pascal: Pyrrhonism vs. Nature José R. Maia Neto The view that Pyrrhonism is not practically viable was, according to Richard H. Popkin, held during the seventeenth and eighteenth centuriesbydifferent philosophers suchas Mersenne,Arnauld, Pascal, Ramsay, and others.1 Among the anti-sceptics, this position was usually taken as an argument against Pyrrhonism. Popkin points out that Hume's main contribution to the "Pyrrhonian controversy" is to show that (i) "the (...) Pyrrhonian doctrine was the logical outcome of philosophical analysis,"2 (ii) that the infeasibility of Pyrrhonism does not weaken its epistemological force but only its psychological plausibility, and (Ui) that this implausibility obtains because nature (the common affairs ofeveryday life and the feeUngs, impressions, and ideas thereby generated) impels the philosopher to believe.3 Popkin alsomakes an allusion to the similaritybetweenHume and Pascal on this issue.4 In this paper I compare the dilemma posed by Pascal as apropaedeutic tofaith withthe "dangerous dilemma" alluded to, but avoided, by Hume in the conclusion of book 1 of the Treatise. The dilemma follows from (i) above. At a certain point in his epistemological enquiry the philosopher is forced tomake a hard choice between the quite disadvantageous alternatives: either to continue his philosophizing, which, leading to Pyrrhonism, may bring despair and cause the annihilation ofhis life, or to abandon philosophy, makinghim aprey ofthe "errors, absurdities, andobscurities"ofanon-critical life.5 In what follows I compare Hume's solution to this dilemma with Pascal's.? In the following passage Hume shows the toughness of the dilemma and offers a first answer to it: What party, then, shall we choose among these difficulties? If we... condemn all refin'd reasoning, we run into the most manifest absurdities. If we reject it in favour of these reasonings, we subvert entirely the human understanding. We have, therefore, no choice left but betwixt a false reason and none at all. For my part, I know not what ought to be done Volume XVII Number 1 41 JOSE R.???? NETO in the present case. I can only observe what is commonly done; which is, that this difficulty is seldom or never thought of; and even where it has once been present to the mind, is quickly forgot, and leaves but a small impression behind it. (T 268) Note that in this first answer Hume manages to avoid the normative response that the dilemma demands. He provides, instead, a descriptive account which is a kind of solution because it purports to show that human psychology makes it unlikely that someone could reach the point at which he or she would have to choose between the two parties. The dilemma does not arise because nature stops the self-subversion ofreason. Most fortunately it happens, that since reason is incapable of dispelling these clouds, nature herselfsuffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent ofmind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. (T 269) Hume means by nature in this passage both human nature and the social and natural environments which, in so far as they demand specific reactions, generate appropriate beliefs. Those beliefs imposed by nature are necessaryforour survival. So, the mere interaction ofthe philosopher with the world outside his closet suffices to dispel his sceptical crisis. According to Hume, this determination of nature is absolute and necessary. "I find myself absolutely and necessarily determin'd to live... I may, nay I must yield to the current ofnature" (T 269). This view is reaffirmed in the Enquiry. Nature is always too strong for principle. And though a PYRRHONIAN may throw himself or others into a momentary amazement and confusion by his profound reasonings; the first and most trivial event in life will put to flight all his doubts and scruples, and leave him the same, in every point ofaction and speculation, with the philosophers of every other sect, or with those who never concerned themselves in any philosophical researches.6 So, it would appear that the dilemma is just a fleeting impression in the imagination of the philosopher during a momentary sceptical crisis. Nature provides that such a crisis is not prolonged... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Academic Skepticism in Early Modern PhilosophyJosé R. Maia NetoAncient skepticism was more influential in the sixteenth and seventeenth centuries than it had ever been before. Thanks to the groundwork of Charles B. Schmitt and Richard H. Popkin on the influence of ancient skepticism in early modern philosophy and to the extensive research that followed their lead, skepticism is now recognized as having played a major role in the rise (...) of modern thought. 1There were two ancient skeptical schools, Academic skepticism and Pyrrhon-ism. Were both equally influential? Until the sixteenth century, Pyrrhonism was scarcely known. Only a few copies of Sextus’s books (the only surviving primary source of ancient Pyrrhonism) have been discovered in medieval libraries. By contrast the main source of Academic skepticism, Cicero’s Aca-demica, was occasionally referred to by medieval authors and was the object of some commentaries and criticism in the Renaissance. 2 Academic skepticism was preserved from the Middle Ages to the Renaissance not only through Cicero’s Academica, but also through Lactantius’s Divinae Institutiones and [End Page 199] Augustine’s Contra Academicos. 3 This situation changed when Sextus’s works were translated to latin and published in 1562 and 1569. Sextus presents a much more complete and detailed account and defense of ancient skepticism than that of Cicero’s Academica. Sextus presents Pyrrhonism as a coherent form of skepticism and Academic skepticism as a kind of negative dogmatism. 4 It was thus natural that the ancient skepticism that fascinated some (and troubled so many) early modern thinkers was mostly Pyrrhonian. Because of the publication of Sextus’s works, according to Schmitt, the increasing influence of Cicero’s Academica in the Renaissance was halted. Sextus’s Hypotyposes and Adversus Mathematicos took the place of Cicero’s Academica and drastically increased the influence of ancient skepticism. 5 The skeptical crisis at the dawn of modern philosophy is called “pyrrhonienne” not “academicienne.”While the appearance of Sextus’s works in Latin turned him and Pyrrhonism into the main source and influence of ancient skepticism in early modern philosophy, further research on the history of skepticism in the period has shown that the role of Cicero’s Academica and of Academic skepticism in general continued to be considerable. First, Cicero’s works were important items in the university curricula. Although Cicero’s works of rhetoric and morals were those more read, the students could certainly learn about Academic skepticism through at least some of them. Second, many editions of De Natura Deorum, a work of Cicero’s in which Academic skepticism is quite central, were published during the seventeenth century. Third, features of Academic skepticism, exhibited above all in Cicero’s Academica, are basic to the skepticism revived in the late Renaissance by Montaigne and Charron; were related to the new science in the first half of the seventeenth century by Gassendi; were used in the anti-Cartesian reaction of the late seventeenth century by Rapin, Huet, Bayle, and above all Foucher; and were radicalized in the eighteenth century by Hume. Despite the Academic features of Montaigne’s, Charron’s, and Gassendi’s skepticisms, it does seem that from the publication of Sextus’s works to the mid-seventeenth century, Academic skepticism was secondary to Pyrrhonism. But the appearance of Descartes and the development of Cartesianism in the second half of the seventeenth century set conditions for a complete revamping of Academic skepticism, bringing about what Schmitt thought was precluded by the appearance of Sextus in the modern scene, namely, a “full flowering of the Academica as a work to inspire new directions of philosophical thought.” 6 [End Page 200]Montaigne’s Apologie pour Raimond Sebond is rightly considered the first major result of the revival of ancient Pyrrhonism in modern thought. 7 Montaigne never cites the name of Sextus nor acknowledges his source and, by contrast, fills his Apology with passages from Cicero on the Academic skeptics. It is clear, however, that Montaigne follows closely Sextus’s Outlines of Pyrrhonism in the central part of the Apology where he gives a detailed and sympathetic exposition of ancient skepticism.After dwelling on the evils and problems arising from knowledge and science, Montaigne...

This article examines the conception of scepticism during the early modern period. It describes how the writings of Pierre Charron and Michel de Montaigne inspired authors to search for a balance between extreme scepticism and what was often described as the dogmatism of the Schools. It discusses the revival of scepticism in the Renaissance and early seventeenth-century philosophy and shows the impact of Cartesian doubt in late seventeenth- and early eighteenth-century scepticism.
