The interest of assigning homework is frequently discussed due to its alleged low impact on student achievement. One of the current lines of research is to emphasize the quality of student homework engagement rather than the amount of time spent on homework. The aim of this study was to determine (a) the extent to which students’ prior achievement affects their homework engagement (i.e., time spent, time management, and amount of teacher-assigned homework done), and (b) how students’ intrinsic motivation towards homework (...) may mediate or moderate the relationship between prior achievement and the homework engagement variables. A large sample of students from the first four years of Secondary Education (N = 1899) completed questionnaires. The results showed that intrinsic motivation partially mediates, but does not moderate, the effect of prior achievement on the three variables related to homework engagement (time spent, time management, and amount of teacher-assigned homework done). These results highlight the importance of considering both students’ current level of achievement and their motivation towards homework engagement when assigning homework. (shrink)

In this paper the scientific trajectory of Spanish influential biochemist Alberto Sols (1917–1989) is presented in comparative perspective. His social and academic environment, his research training under the Cori's in the US in the early 1950s and his works when coming back to Spain to develop his own scientific career are described in order to present the central argument of this paper on his path from physiological research to research on enzymatic regulation. Sols' main contributions were both scientific and academic. (...) He and his collaborators not only contributed to biological knowledge on the biochemistry of metabolic regulation but to the active reception of biochemistry in the Spanish academia and to update of Spanish medical education. -/- .

We prove that the classes of UHF algebras and AF algebras, while not axiomatizable, can be characterized as those C*-algebras that omit certain types in the logic of metric structures.

By pitting John Cage against Andy Warhol, Arthur Danto shows how the arts themselves were gripped by a progressive logic that aimed at only one goal: to overcome the gap between art and life. The non‐tautological reading preserves a fundamental, philosophical difference between commonplace and art objects. The semantical space accounts for the aboutness of the work and is thus the necessary condition for something to be an artwork. Together with other Pop artists, Rauschenberg transformed the Artworld, while Cage aimed (...) at a re‐enfranchisement of the commonplace. Danto writes that his Buddhist phase came to an end when he, as a philosopher, felt the need for theories. The works of Fluxus and Cage, in the end, accepted asylum within the sanctuary of the Artworld, where they became less radical, and perhaps less radical than Pop. (shrink)

A Turing degreedis the degree of categoricity of a computable structure${\cal S}$ifdis the least degree capable of computing isomorphisms among arbitrary computable copies of${\cal S}$. A degreedis the strong degree of categoricity of${\cal S}$ifdis the degree of categoricity of${\cal S}$, and there are computable copies${\cal A}$and${\cal B}$of${\cal S}$such that every isomorphism from${\cal A}$onto${\cal B}$computesd. In this paper, we build a c.e. degreedand a computable rigid structure${\cal M}$such thatdis the degree of categoricity of${\cal M}$, butdis not the strong degree of categoricity (...) of${\cal M}$. This solves the open problem of Fokina, Kalimullin, and Miller [13].For a computable structure${\cal S}$, we introduce the notion of the spectral dimension of${\cal S}$, which gives a quantitative characteristic of the degree of categoricity of${\cal S}$. We prove that for a nonzero natural numberN, there is a computable rigid structure${\cal M}$such that$0\prime$is the degree of categoricity of${\cal M}$, and the spectral dimension of${\cal M}$is equal toN.

Computably enumerable equivalence relations received a lot of attention in the literature. The standard tool to classify ceers is provided by the computable reducibility \. This gives rise to a rich degree structure. In this paper, we lift the study of c-degrees to the \ case. In doing so, we rely on the Ershov hierarchy. For any notation a for a non-zero computable ordinal, we prove several algebraic properties of the degree structure induced by \ on the \ equivalence relations. (...) A special focus of our work is on the existence of infima and suprema of c-degrees. (shrink)

In daily academic life, students are exposed to a wide range of potentially stressful situations which could negatively affect their academic achievement and their health. Among the factors that could be weakened by academic stress, attention has been paid to expectations of self-efficacy, which are considered one of the most important determinants for student engagement, persistence, and academic success. From a proactive perspective, research on academic stress has emphasized the importance of coping strategies in preventing harmful consequences. In recent years, (...) there has been a growing interest in discovering the extent to which individuals are able to combine different coping strategies and the adaptive consequences this flexibility entails. However, studies using this person-centered approach are still scarce in the academic context. On that basis, this current study had two objectives: (a) to examine the existence of different profiles of university students based on how they combined different approach coping strategies (positive reappraisal, support seeking, and planning); and (b) to determine the existence of differences in general expectations of self-efficacy between those coping profiles. 1072 university students participated in the study. The coping profiles were determined by Latent Profile Analysis (LPA). The differences in the self-efficacy variable were determined using ANCOVA, with gender, university year, and degree type as covariates. Four approach coping profiles were identified: (a) low generalized use of approach coping strategies; (b) predominance of social approach coping approaches; (c) predominance of cognitive approach coping approaches; (d) high generalized use of approach coping strategies. The profile that showed that a greater combination of the three strategies was related to higher general self-efficacy expectations, and vice versa. These results suggest that encouraging flexibility in coping strategies would help to improve university students’ self-efficacy. (shrink)

Given a d.c.e. degree d, consider the d.c.e. sets in d and the corresponding degrees of their Lachlan sets. Ishmukhametov provided a systematic investigation of such degrees, and proved that for a given d.c.e. degree d > 0, the class of its c.e. predecessors in which d is c.e., denoted as R[d], can consist of either just one element, or an interval of c.e. degrees. After this, Ishmukhametov asked whether there exists a d.c.e. degree d for which the class R[d] (...) has no minimal element. We give a positive answer to this question. (shrink)

The problem of life’s origin remains one of the great outstanding challenges to science. Ever since Charles Darwin mused about a “warm little pond” incubating life beneath sunny primeval skies, scientists have speculated about the exact location of this transforming event. Nearly a century and a half later, we remain almost completely ignorant of the physical processes that led from a nonliving chemical mixture to the first autonomous organism. However, some progress at least has been made on tracking down where (...) and when life first established itself on Earth. Fossil evidence suggests that the biological record extends back at least 3.5 billion years, pointing to a still earlier origin1. But this presents a problem. The cratering record of the moon implies that Earth was subjected to intense bombardment by large comets and asteroids over an extended duration until about 3.8 billion years ago. The largest of these impacts would have released enough energy to swathe the planet in incandescent rock vapour, boiling the oceans and sending sterilizing heat pulses a kilometre into the exposed crust2. This unpromising setting – hardly a secure one for warm little ponds – has prompted some astrobiologists to conjecture that life began somewhere else and came to Earth readymade3. Favourite among extraterrestrial originating locations is the planet Mars4. (shrink)

Pomeau has condensed a lot of material for this pocket-size introduction to the life and works of Diderot, which he has attempted to simplify by providing parallel classifications of the excerpts from Diderot's works with his own presentation of Diderot's philosophy. These divisions are entitled: the Adventure of Diderot's thought, On Nature, On Man, Morality, Aesthetics, Politics, and the Contemporary Import of Diderot's Philosophie. Pomeau, a Voltaire scholar, displays a knowledge of the intellectual history of the period and a wide (...) acquaintance with his immediate material. His selections are beautifully chosen, for they provide a generous survey of Diderot's work, including even a short passage from the most recently published marginalia of Hemsterhuis. This sort of presentation cannot but entice the beginner to further examination, for the passages range from the most poignant to the most witty Yet there is matter to frustrate the serious beginner; the passages are not dated, nor are they identified by work in the index. Pomeau engages in gratuitous psychologizing in his exposition of Diderot's life, and has made a blatant error in attributing to Diderot the authorship of the article "Encyclopédie." These shortcomings unfortunately mar a text which contains excellent analyses of the evolution of Diderot's religious and biological thought.—C. M. R. (shrink)

The author considers the conditions which render possible communication and signifying. Acknowledging that most of the literature now published deals with Anglo-Saxon and Germanic studies, he hopes to effect an application to the Italian language and way of thinking. His arguments are difficult to appreciate because they begin from too broad a base of assumptions. Although having emphasized a desire to strengthen the case for "common sense," he seems brutally to neglect that ideal. Rossi-Landi assumes that all language is construction (...) and accepts as an immediate corollary that thought is another construction. From this basis he pursues faithfully a value-free, historicist-oriented explanation of language which is marred by reasoning that abounds in non-sequitur. No one will deny the interest of the original problem, nor its relevance to the question of philosophy; it is to be regretted that more careful arguments have not been offered.--C. E. B. (shrink)

An historical and critical survey of the various theories of totemism. Lévi-Strauss believes almost every theory explaining the relation held to exist between man and certain natural objects can be demolished: there seems to be no general biological or cultural framework which can account for totemism as an isolated phenomenon. But if totemism is seen as a way of thinking metaphorically, of correlating opposites, or of associating by contrariety then it becomes an example of a mode of thinking common to (...) sophisticated as well as primitive peoples. Observations by Bergson and Rousseau, made outside the framework of modern anthropology, bear out Lévi-Strauss' thesis. A fascinating work, marred only by a rather stiff translation.—C. L. B.

With the end of the Cold War, political and ideological competition has decreased as a stated reason for space exploration. The possibility of establishing a settlement on Mars is being seriously evaluated by state and commercial space agencies, which includes objectives to expand human civilization and ensure the continuity of the human species. The technological challenges associated with space settlement continue to receive significant attention, but the success of space settlement will also depend on other human factors. This study (...) presents a high-level overview of some potential issues that could arise with the development of a permanent populationand a space economyon Mars. This study highlights some of the anticipated problems of overnance, trade, production, and proliferation that will need pragmatic solutions to ensure the sustainability of a martian settlement. This paper is intended to instigate further discussion and research regarding human and economic factors that could enable or constrain future settlements on Mars. (shrink)

A general consensus has emerged among twentieth-century commentators on the Aeneid that pater ipse…superum must be taken together and understood as referring to the father of the gods and not to Mars, sire of Romulus. What remains a subject of debate is the meaning of honor here and its particular association with Jupiter. Does it betoken the abstraction itself or a concrete manifestation of it? Austin, following Donatus, opts for the former alternative , Norden and R. D. Williams for (...) the latter. Of these the first finds a reference to the Zeus-given sceptre of kings, the second to Jove's thunderbolt. The language of the passage argues in favour of metonymy for two reasons. First, we expect Anchises, when showing off Romulus, to adhere to the pattern he has already set in the two portions of his parade which have preceded. In the case of the initial hero, Silvius, we attend largely to genealogical background . The second segment, a group made up of Procas, Capys, Numitor and Aeneas Silvius, elicits from Aeneas' father a series of exclamations on the valour of their res gestae . Yet each also has a tangible symbol of martial virtus that distinguishes him. (shrink)

The hypothesis that life’s rapid appearance on Earth justifies the belief that life is widespread in the universe has been investigated mathematically by Lineweaver and Davis (Astrobiol- ogy 2002;2:293–304). However, a rapid appearance could also be interpreted as evidence for a nonterrestrial origin. I attempt to quantify the relative probabilities for a non-indigenous ver- sus indigenous origin, on the assumption that biogenesis involves one or more highly im- probable steps, using a generalization of Carter’s well-known observer-selection argument. The analysis is (...) specifically applied to a Martian origin of life, with subsequent transfer to Earth within impact ejecta. My main result is that the relatively greater probability of a Mar- tian origin rises sharply as a function of the number of difficult steps involved in biogene- sis. The actual numerical factor depends on what is assumed about conditions on early Mars, but for a wide range of assumptions a Martian origin of life is decisively favored. By con- trast, an extrasolar origin seems unlikely using the same analysis. These results complement those of Lineweaver and Davis.

Walsh admirably achieves the objective of this book, which is to supply the need for a lucid commentary on Kant’s first Critique that is both faithful to making the text clear and a sophisticated assessment of the arguments. Walsh’s work exemplifies patience, scholarship, and philosophical acumen. In response to the conventional criticism that Kant’s theses are marred by a psychological idiom, Walsh translates Kant into the contemporary linguistic idiom in a way that preserves the original remarkably well.

Tycho Brahe was not just an observer; he was a skilled theoretical astronomer, as his lunar and solar models show. Still, even if he is recognized for proposing the Geoheliocentric system, little do we know of the technical details of his planetary models, probably because he died before publishing the last two volumes of his Astronomiae Instaurandae Progymnasmata, which he planned to devote to the planets. As it happens, however, there are some extant drafts of his calculations in Dreyer’s edition (...) of Tycho’s Opera Omnia under the name Calculi ad Corrigenda Elementa orbitae Saturni, which, to the best of my knowledge, have not yet been analyzed before. In these manuscripts, Tycho starts with calculations based on the Prutenic Tables and makes a series of adjustments to the mean longitude, the longitude of the apogee, and the eccentricity to fit a series of observations of oppositions. In doing that, Tycho describes and applies a new method for obtaining accurate values for the parameters of the superior planets, he develops a divided eccentricity model of Saturn, similar to the one we know Longomontanus and Kepler applied to Mars, and finally he realizes that the true position of the Sun somehow affects the motion of Saturn around the zodiac and develops a method to correct the position of Saturn as a function of solar equation of anomaly. So, a close analysis of the calculations reveals details of the Tychonic planetary models unknown until now. The present study analyzes these drafts. (shrink)

In this Matters Arising article, we outline how the recent article “The impact on patients of objections by institutions to assisted dying: a qualitative study of family caregivers’ perceptions” (White et al., 2023 Mar 13;24(1):22) informed Voluntary Assisted Dying (VAD) implementation in our large Australian public health setting, where objections do not emanate from, but within, the institution. In reporting the harms to patients and caregivers created by institutional objection, White et al. provide an evidenced-based road map for potential potholes (...) or risks associated with VAD implementation. We discuss the complexities emerging from the diverse views of health professionals and the ethical tensions arising from such, especially within certain specialties, and how we developed systemic strategies that support patients, caregivers and staff alike. We highlighted the need to shift from “Do you support VAD?“ to “How can we support you as healthcare professionals to integrate VAD into your practice, in a way that complies with the legislation, meets the needs of patients and caregivers, and feels safe and does not compromise your moral stance?“.
