Both male ornamentation and male combat result in increased male mortality. Because population sizes are limited by a carrying capacity, increased age-specific adult male mortality will result in decreased age-specific adult female mortality, as well as decreased juvenile mortality. As intersexual competition is one form of intraspecific competition, through choosing to mate with ornamented and/or combative males, females in polygamous systems reduce intraspecific competition. Because average male fitness must exactly equal average female fitness, male fitness will paradoxically rise with increasing (...) male mortality. This theory also offers new perspectives on peripheral problems to sexual theory, such as mate location, resource guarding, leks, harems, and others. (shrink)

Interpreting John Paul II's message to the Pontifical Academy of Sciences in the context of the new scientific discoveries concerning the mitochondrial DNA, one can argue that the human species emerged in Africa some 200,000 years ago. The very problem of the emergence of the human soul in the process of biological evolution represents a subject outside the cognitive competence of science. Attempts can be undertaken to explain this issue in the epistemological perspective of philosophy and theology. In traditional versions (...) of evolutionary theism, God* s interaction in nature was interpreted in causal categories when deterministic dependences were stressed in the process of evolutionary growth. In new proposals, God's presence in an evolving nature has been explained in categories of potentialities and propensities built by God into an evolving Nature. Consequently, in this approach God could be conceived not as a Paleyan designer but rather as a composer unfolding the possibilities hidden in His creation. The future of the evolutionary process depends not only on cosmic physical determinants; it depends to a large extent on the quality of cooperation of human actions with the influence of the Divine Creator. Accordingly, the shape of human culture, as well as the state of moral consciousness of Homo sapiens, should be taken into consideration to discuss the future evolution of the human species. /// Interpretando a mensagem do Papa João Paulo II à Academia Pontifícia das Ciências no contexto das novas descobertas científicas referentes ao DNA mitocondrial, o autor do artigo considera ser possível defender que a espécie humana surgiu em África há cerca de 200 000 anos. Mas o problema da emergência da alma humana no contexto do processo da evolução biológica representa um assunto que está fora da competência cognitiva da ciência. Contudo é possível realizar tentativas no sentido de explicar esta questão na perspectiva epistemológica da filosofia e da teologia. Nas versões tradicionais do teísmo evolutivo, a interacção de Deus com a natureza era interpretada segundo categorias causais quando as dependências deterministicas eram sublinhadas no processo do desenvolvimento evolutivo. No contexto de novas propostas interpretativas, a presença de Deus na ordem evolutiva tem sido explicada em termos das potencialidades e das propensidades induzidas por Deus na Natureza em evolução. Consequentemente, segundo esta abordagem Deus poderia ser concebido não como sábio projectista de que fala William Paley, mas antes como um compositor fazendo vir ao de cima as possibilidades escondidas na sua própria criação. O futuro do processo evolutivo depende não apenas das determinantes físicas do cosmos; ele depende em larga medida da qualidade da cooperação das acções humanas com a influência do Criador. Neste sentido, o artigo defende que a forma da cultura humana, bem como o estado da consciência moral do homo sapiens deve ser tido em consideração em ordem a se poder discutir a evolução futura da espécie humana.

Climate models calibrated exclusively with observations from the 19th through 21st centuries are unsuitable for assessing many important hypotheses about the future. Many systems in the modern climate are expected to cross dynamic thresholds in the near future, requiring more than the instrumental record for adequate calibration. In this paper I argue that paleoclimate analogues from earth’s past can mitigate this threshold problem, even if the modern climate exhibits features that make it historically unique. While this requires that paleoclimatologists be (...) increasingly discriminate in the past systems they target for modern analogues, the upshot is a practice of climate model construction that improves the reliability of future projections. All of this is achieved by integrating features of past climate systems discovered by the study of earth deep in the past. My analysis synthesizes important empirical work done by climate modelers and paleoclimatologists with relevant philosophical work on analogical reasoning in science. (shrink)

In this paper we argue that the difference between standard measurement and proxy measurement in paleoclimatology should not be understood in terms of ‘directness’. Measurements taken by climatologists to be paradigmatically non-proxy exhibit the kinds of indirectness that are thought to separate them proxy measurement. Rather, proxy measurements and standard measurements differ in how they account for confounding causal factors. Measurements are ‘proxy’ to the extent that the measurements require vicarious controls, while measurements are not proxy, but rather ‘standard’, to (...) the extent that the measurement apparatus provides sufficient physical control on its own. Guided by this account of proxy measurement, we then consider some of the challenges specific to historical proxy measurement and how it is that historical scientists address these challenges. Historical scientists rely on significant causal dependencies and naturally preserved signals to mitigate the influence of destructive processes over time. (shrink)

This article questions the widespread use of experimental social psychology to understand real-world group disparities. Standard experimental practice is to design studies in which participants make judgments of targets who vary only on the social categories to which they belong. This is typically done under simplified decision landscapes and with untrained decision-makers. For example, to understand racial disparities in police shootings, researchers show pictures of armed and unarmed Black and White men to undergraduates and have them press “shoot” and “don't (...) shoot” buttons. Having demonstrated categorical bias under these conditions, researchers then use such findings to claim that real-world disparities are also due to decision-maker bias. I describe three flaws inherent in this approach, flaws which undermine any direct contribution of experimental studies to explaining group disparities. First, the decision landscapes used in experimental studies lack crucial components present in actual decisions. Second, categorical effects in experimental studies are not interpreted in light of other effects on outcomes, including behavioral differences across groups. Third, there is no systematic testing of whether the contingencies required to produce experimental effects are present in real-world decisions. I apply this analysis to three research topics to illustrate the scope of the problem. I discuss how this research tradition has skewed our understanding of the human mind within and beyond the discipline and how results from experimental studies of bias are generally misunderstood. I conclude by arguing that the current research tradition should be abandoned. (shrink)

There is a need for empirically based research on social and ethical challenges related to informed consent processes, particularly in studies focusing on adolescent sexual and reproductive health. In a pilot study of a school-based pregnancy prevention intervention in rural Zambia, the majority of the guardians who were asked to consent to their daughters’ participation, refused. In this paper we explore the reasons behind the low participation in the pilot with particular attention to challenges related to the community engagement and (...) informed consent process. The pilot was implemented in two schools and examined the acceptability of a package of interventions including economic support to families to keep their girls in school, pocket money for girls, youth club meetings on reproductive health, and community meetings to sensitize the community. Focus group discussions were conducted with girls who participated in the pilot, boys in their class and with parents. Individual semi-structured interviews were conducted with teachers, peer educators and community health workers involved in the coordination of the intervention as well as with religious and traditional leaders. Data were analyzed through thematic analysis. The findings indicate that inadequate use of recognized community communication channels during the community engagement process and dissemination of information about the pilot resulted in limited understanding of the pilot concept by the community. This surfaced through uncertainty and fear that the intervention may result in loss of control over daughters, worries about why money was provided unconditionally to girls, and suspicion of links to satanism. The sense of insecurity appeared to be exacerbated by low literacy levels, poverty, fear of loss of bride wealth, perceived disregard for local perceptions of social status, and scanty trust in the actors implementing the pilot. Inadequate use of locally appropriate channels in the dissemination of information created room for interpretation and facilitated development of mistrust, undermining the conditions for community engagement and actual informed consent. A key lesson learnt is the importance of taking seriously the complexity of local values and structures that may impact people’s capability to consent or not consent to a study in an informed manner.

. In this paper I present two ways in which climate modelers use general circulation models for exploratory purposes. The complexity of Earth’s climate system makes it difficult to predict precisely how lower-order climate dynamics will interact over time to drive higher-order dynamics. The same issues arise for complex models built to simulate climate behavior like the Community Earth Systems Model. I argue that as a result of system complexity, climate modelers use general circulation models to perform model dynamic exploration (...) and climate dynamic exploration. MDE and CDE help climate modelers to better understand the dynamic structure of the general circulation model system and the actual climate system, respectively. (shrink)

Most causal discovery algorithms in the literature exploit an assumption usually referred to as the Causal Faithfulness or Stability Condition. In this paper, we highlight two components of the condition used in constraint-based algorithms, which we call “Adjacency-Faithfulness” and “Orientation- Faithfulness.” We point out that assuming Adjacency-Faithfulness is true, it is possible to test the validity of Orientation- Faithfulness. Motivated by this observation, we explore the consequence of making only the Adjacency-Faithfulness assumption. We show that the familiar PC algorithm has (...) to be modified to be correct under the weaker, Adjacency-Faithfulness assumption. The modified algorithm, called Conservative PC (CPC), checks whether Orientation- Faithfulness holds in the orientation phase, and if not, avoids drawing certain causal conclusions the PC algorithm would draw. Howtion: ever, if the stronger, standard causal Faith-. (shrink)

Martin Heidegger’s writings on Hegel are notoriously difficult but show an essential engagement between two of the foundational thinkers of phenomenology. Joseph Arel and Niels Feuerhahn provide a clear and careful translation of Volume 68 of the Complete Works, which is comprised of two shorter texts—a treatise on negativity, and a penetrating reading of Hegel’s Phenomenology of Spirit. In this volume, Heidegger relates his interpretation of Hegel to his own thought on the event, taking up themes developed in Contributions (...) to Philosophy. While many parts of the text are fragmentary in nature, these interpretations are considered some of the most significant as they bring Hegel into Heidegger’s philosophical trajectory. (shrink)

Au Centre Pompidou-Metz, faisant écho à l'exposition inaugurale, un colloque international a étudié de manière pluridisciplinaire et transversale la question du chef-d'œuvre. Loin de se focaliser sur le débat esthétique, les diverses approches ont assigné le droit, l'histoire, la sociologie, l'économie et les sciences exactes, pour mieux soumettre cet "objet" à un véritable examen clinique. Cette question ne serait-elle plus d'actualité? Loin s'en faut! Entre cœur et raison, la sacralisation des œuvres d'art produit toujours autant de savoirs, de savoir-faire et (...) de savoirs sur le faire.

Participation in competition festivals—where students and ensembles compete against each other for high scores and accolades—is a widespread practice in North American formal music education. In this article, I use Marx's theories of labor, value, and phantasmagoria to suggest a capitalist logic that structures these competitions. Marx's theories might suggest that one of musical performance's educational use-values is its function as a representation of the labor of musical learning. Competitions reward the hiding of this use-value by privileging performances that conceal (...) the labor of musical learning. In hiding this use-value, the performance's exchange-value, or "price," is increased by gaining a higher score. In this way, competitions are phantasmagoric: they conceal learning within the performance in thrall of the exchange-value of a high score. Despite these flaws in competitions, educators and students might exploit competition festivals' value of coming together and comparing learning with others. Rather than retreating from competition festivals, educators might transform them by imagining renewed practices where students and educators come together to share their learning through performance, listening, and dialogue.

Herbert Morris argues in his influential retributivist paper, "Persons and Punishment," that criminals deserve punishment because their actions represent an unfair distribution of benefits and burdens in society. The proper distribution of benefits and burdens is important, in part, to restore law abiding citizens’ confidence that others will follow the law. In this paper I show that Morris's argument for why criminals deserve punishment morally requires us to set up an institution of rehabilitation in addition to the institution of punishment. (...) Such an institution is morally required because neither pure punishment systems nor punishment systems that incorporate quasi-rehabilitative aspects have ever worked to uphold the necessary confidence that Morris tells us law abiding citizens must have in order to protect the social order. Moreover, we cannot abandon Morris's appeal to the duty to maintain social order without also abandoning a plausibly Morrisian framework. (shrink)

We once took death to be a permanent part of human experience. This is no longer the case. As death, and its allies pain and suffering, have increasingly become subject to medical treatment and social control, we think of them in new ways. However, as important as this fundamental transformation is, I have chosen to discuss something entirely different in this essay: I contend here that death has a particular sting for us of the contemporary world since we lack stories (...) and metaphors to talk about it.

There is growing interest in developing co-operation between adult literacy researchers and practitioners to further research skills and approaches. Canada’s National Literacy Secretariat has recently initiated a series of policy debates that suggested several possibilities: targeted research grants, research internships for practitioners, practical sabbaticals for researchers, support for networking between literacy researchers and practitioners, and joint seminars and workshops between researchers and practitioners. A common theme throughout these discussions is the need to develop critical thinking about both collaborative research and (...) adult literacy. In this paper we discuss two collaborative initiatives between university-based researchers and adult literacy groups in the provinces of British Columbia and Ontario. Each project was based on the notion of “research circles” and specifically designed to enhance research capacity and critical thinking about literacy research. (shrink)

Given the excessive moralization of human rights and their universal ideologization, which has led to unfortunate consequences such as erasure of cultural differences and standardization, given the right, and even the duty, to intervene (the right of the strongest), and the craze for ‘democracy’ despite the will of peoples, the time has come to undertake an academic analysis of the founding texts in order to make them intelligible, in spite of the fact that human rights have become a bible. Even (...) the revealed word of the Bible is scrutinized by exegetical analysis, historical criticism and hermeneutics, which have not stopped it surviving. It should be the same for human rights.

Patriotism is a form of loyalty. The range of loyalty is from patriotism to friendship. Liberals were often accused of having no sense of loyalty. They usually tend to deny the charge — even while refusing to take a loyalty oath. Even the liberal philosopher Sir Karl Popper has claimed (Open Society, i, ch. 10), that liberals can be better patriots than others. 1 find this line of defense erroneous and morally wrong. I find it much nicer, much more honest, (...) to join Martin Buber in his taking Jeremiah as a model because when he felt that capitulation to the enemy is morally justified he recommended just that.
