Rape of women by men might be generated either by a specialized rape adaptation or as a by-product of other psychological adaptations. Although increasing number of sexual partners is a proposed benefit of rape according to the “rape as an adaptation” and the “rape as a by-product” hypotheses, neither hypothesis addresses directly why some men rape their long-term partners, to whom they already have sexual access. In two studies we tested specific hypotheses derived from the general hypothesis that sexual coercion (...) in the context of an intimate relationship may function as a sperm competition tactic. We hypothesized that men’s sexual coercion in the context of an intimate relationship is related positively to his partner’s perceived infidelities and that men’s sexual coercion is related positively to their mate retention behaviors (behaviors designed to prevent a partner’s infidelity). The results from Study 1 (self-reports from 246 men) and Study 2 (partner-reports from 276 women) supported the hypotheses. The Discussion section addresses limitations of this research and highlights future directions for research on sexual coercion in intimate relationships. (shrink)

Cuckoldry is an adaptive problem faced by parentally investing males of socially monogamous species (e.g., humans and many avian species). Mate guarding and frequent in-pair copulation (IPC) may have evolved as anti-cuckoldry tactics in avian species and in humans. In some avian species, the tactics are used concurrently, with the result that mate guarding behaviors and IPC frequency are correlated positively. In other avian species, the tactics are compensatory, with the result that mate guarding behaviors and IPC frequency are correlated (...) negatively. The relationship between mate guarding and IPC frequency in humans is unknown. Avian males that use these tactics concurrently share with human males an inability to guard a female partner continuously during her peak fertile period. We hypothesized, therefore, that men’s mate guarding and IPC frequency function as concurrent anti-cuckoldry tactics, resulting in a positive correlation between them. Study 1 (n=305) secured men’s self-reports of mate guarding and IPC frequency. Study 2 (n+367) secured women’s reports of their partners’ mate guarding and IPC frequency. The concurrent tactics hypothesis was supported in both studies: Men’s mate guarding and IPC frequency are correlated positively, and this association is not attributable to male age, female age, relationship satisfaction, relationship length, or time that the couple spends together. The Discussion section addresses potential limitations of this research and future research directions. (shrink)

Schmitt recognized that research is needed to identify other factors associated with sex ratio and with sociosexuality that may explain cross-cultural variation in sexual behavior. One such factor may be the risk of sperm competition. Sperm competition theory may lead us to a more complete explanation of cultural variation in sexual behavior.

At the forefront of international concerns about global legislation and regulation, a host of noted environmentalists and business ethicists examine ethical issues in consumption from the points of view of environmental sustainability, economic development, and free enterprise.

Background The European Union aims to optimize patient protection and efficiency of health-care research by harmonizing procedures across Member States. Nonetheless, further improvements are required to increase multicenter research efficiency. We investigated IRB procedures in a large prospective European multicenter study on traumatic brain injury, aiming to inform and stimulate initiatives to improve efficiency. Methods We reviewed relevant documents regarding IRB submission and IRB approval from European neurotrauma centers participating in the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury. (...) Documents included detailed information on IRB procedures and the duration from IRB submission until approval. They were translated and analyzed to determine the level of harmonization of IRB procedures within Europe. Results From 18 countries, 66 centers provided the requested documents. The primary IRB review was conducted centrally or locally and primary IRB approval was obtained after one, two or three review rounds with a median duration of respectively 50 and 98 days until primary IRB approval. Additional IRB approval was required in 55% of countries and could increase duration to 535 days. Total duration from submission until required IRB approval was obtained was 114 days and appeared to be shorter after submission to local IRBs compared to central IRBs. Conclusion We found variation in IRB procedures between and within European countries. There were differences in submission and approval requirements, number of review rounds and total duration. Research collaborations could benefit from the implementation of more uniform legislation and regulation while acknowledging local cultural habits and moral values between countries. (shrink)

According to N. T. Wright, anyone who is a Christian should at least think twice before he or she speaks about the soul, especially as an entity that is distinct from its physical body and can survive death in a disembodied intermediate state until the resurrection and reembodiment. In Wright’s mind, talk of the soul is talk about soul-body substance dualism (dualism, for short), which is the villain in Christian anthropological thought. As far as Wright is concerned, it is time (...) for Christians to renounce dualism once and for all. In this paper, I take issue with Wright’s position on substance dualism. (shrink)

It's an achievement of the last couple of decades that people who work in linguistic semantics and people who work in the philosophy of language have arrived at a friendly, de facto agreement as to their respective job descriptions. The terms of this agreement are that the semanticists do the work and the philosophers do the worrying. The semanticists try to construct actual theories of meaning (or truth theories, or model theories, or whatever) for one or another kind of expression (...) in one or another natural language; for example, they try to figure out how the temperature could be rising compatibly with the substitutivity of identicals. The philosophers, by contrast, keep an eye on the large, foundational issues, such as: what's the relation between sense and denotation; what's the relation between thought and language; whether translation is determinate; and whether life is like a fountain. Every now and then the philosophers and the semanticists are supposed to get together and compare notes on their respective progress. Or lack thereof. (shrink)

The use of language models in Web applications and other areas of computing and business have grown significantly over the last five years. One reason for this growth is the improvement in performance of language models on a number of benchmarks — but a side effect of these advances has been the adoption of a “bigger is always better” paradigm when it comes to the size of training, testing, and challenge datasets. Drawing on previous criticisms of this paradigm as applied (...) to large training datasets crawled from pre-existing text on the Web, we extend the critique to challenge datasets custom-created by crowdworkers. We present several sets of criticisms, where ethical and scientific issues in language model research reinforce each other: labour injustices in crowdwork, dataset quality and inscrutability, inequities in the research community, and centralized corporate control of the technology. We also present a new type of tool for researchers to use in examining large datasets when evaluating them for quality. (shrink)

1 There is a Standard Objection to the idea that concepts might be prototypes (or exemplars, or stereotypes): Because they are productive, concepts must be compositional. Prototypes aren't compositional, so concepts can't be prototypes (see, e.g., Margolis, 1994).2 However, two recent papers (Osherson and Smith, 1988; Kamp and Partee, 1995) reconsider this consensus. They suggest that, although the Standard Objection is probably right in the long run, the cases where prototypes fail to exhibit compositionality are relatively exotic and involve phenomena (...) which any account of compositionality is likely to find hard to deal with; for example, the effects of quantifiers, indexicals, contextual constraints, etc. KP are even prepared to indulge a guarded optimism: "... when a suitably rich compositional theory... is developed, prototypes will be seen ... as one property among many which only when taken altogether can support a compositional theory of combination" (p.56). In this paper, we argue that the Standard Objection to prototype theory was right after all: The problems about compositionality are insuperable in even the most trivial sorts of examples; it is therefore as near to certain as anything in cognitive science ever gets that the structure of concepts is not statistical. Theories of categorization, concept acquisition, lexical meaning and the like, which assume the contrary simply don't work. We commence with a general discussion of the constraints that an account of concepts must meet if their compositionality is to explain their productivity. We'll then turn to a criticism of proposals that OS2 and KP make for coping with some specific cases. (shrink)

Plato did it. Aristotle did it. All the great philosophers did it. You do it and we do it: we draw philosophical conclusions from linguistic data. Although we all do it, the degree, manner, and intensity to which it is done varies. Some have made piecemeal observations about language (e.g., “all these different things have the same term predicated of them”) to draw metaphysical conclusions (e.g., “there is some one existing thing that all these different entities share”). Others have made (...) observations about how all people – or at least, some important subset of them – employ a term (e.g., “we don’t say an action is voluntary unless we wish to say that it was done for (or in) an unusual reason (or manner)”) to draw conclusions about human agency (e.g., “actions that are done in the normal way in the normal course of events are neither free nor compulsory”). And others have looked to how people would talk were certain actual conditions not to be true (e.g., “we would say that we were still talking about Aristotle even if it were to turn out that he didn’t teach Alexander the Great”) to infer necessary features of the semantic realm (e.g., that some propositions must contain an actual individual and not a description of an individual). Still others have looked to empirical results from the science of linguistics (e.g., “the types of complements allowed by the verbs believes and knows are different”) to draw epistemological conclusions (e.g., “knowledge of something does not imply belief of it”), or again “the distributional facts concerning knows that and knows how are the same” to draw the conclusion “practical knowledge is a kind of theoretical knowledge”.

Two leaders in the field offer a compelling analysis of the current state of the art and reveal the steps we must take to achieve a truly robust artificial intelligence. Despite the hype surrounding AI, creating an intelligence that rivals or exceeds human levels is far more complicated than we have been led to believe. Professors Gary Marcus and Ernest Davis have spent their careers at the forefront of AI research and have witnessed some of the greatest milestones in (...) the field, but they argue that a computer beating a human in Jeopardy! does not signal that we are on the doorstep of fully autonomous cars or superintelligent machines. The achievements in the field thus far have occurred in closed systems with fixed sets of rules, and these approaches are too narrow to achieve genuine intelligence. The real world, in contrast, is wildly complex and open-ended. How can we bridge this gap? What will the consequences be when we do? Taking inspiration from the human mind, Marcus and Davis explain what we need to advance AI to the next level, and suggest that if we are wise along the way, we won't need to worry about a future of machine overlords. If we focus on endowing machines with common sense and deep understanding, rather than simply focusing on statistical analysis and gatherine ever larger collections of data, we will be able to create an AI we can trust--in our homes, our cars, and our doctors' offices. Rebooting AI provides a lucid, clear-eyed assessment of the current science and offers an inspiring vision of how a new generation of AI can make our lives better. (shrink)

It’s been, for some time now, a pet thesis of ours that compositionality is the key constraint on theories of linguistic content. On the one hand, we’re convinced by the usual arguments that the compositionality of natural languages1 explains how L-speakers can understand any of the indefinitely many expressions that belong to L.2 And, on the other hand, we claim that compositionality excludes all “pragmatist”3 accounts of content; hence, practically all of the theories of meaning that have been floated by (...) philosophers and cognitive scientists for the last fifty years or so. A number of objections to our claim have been suggested to us, but none that we find persuasive (see, for example, the discussions of the “uniformity principle” and of “reverse compositionality” in Fodor and Lepore 2002). These objections have a common thread: they all grant that mental and linguistic content are compositional but challenge the thesis that compositionality is incompatible with semantic pragmatism. In this paper, we want to consider an objection of a fundamentally different kind, namely, that it doesn’t matter whether compositionality excludes semantic pragmatism because compositionality isn’t true; the content of an expression supervenes not on its linguistic structure4 alone but on its linguistic structure together with the context of its tokening.5..

It matters to a number of projects whether monomorphemic lexical items (‘boy’, ‘cat’, ‘give’, ‘break’, etc.) have internal linguistic structure. (Call the theory that they do the Decomposition Hypothesis (DC).) The cognitive science consensus is, overwhelmingly, that DC is true; for example, that there is a level of grammar at which ‘breaktr’ has the structure ‘cause to breakint’ and so forth. We find this consensus surprising since, as far as we can tell, there is practically no evidence to support it. (...) (For example, there is no psychological evidence that you can’t have a word that expresses the concept BREAKTR unless you have the concept CAUSE. But there ought to be if CAUSE is a constituent of BREAKTR) This isn’t, of course, to say that there are no prima facie arguments at all for DC. The best one’s we’ve heard are the Impossible Word Arguments (IWA). That being so we’re very interested in whether IWAs are, in fact, sound. (shrink)
