Partner preferences are expressed by many social species, including humans. They are commonly observed as selective contacts with an individual, more time spent together, and directed courtship behavior that leads to selective copulation. This review discusses the effect of conditioning on the development of heterosexual and homosexual partner preferences in rodents. Learned preferences may develop when a conditioned stimulus (CS) is associated in contingency with an unconditioned stimulus (UCS) that functions as a reinforcer. Consequently, an individual may display preference (...) for a partner that bears a CS. Some UCS may be more or less reinforcing, depending on when they are experienced, and may be different for males and females. For example, it could be that, only during periods of early development, that stimuli associated with nurture and juvenile play become conditioned. In adulthood, other stimuli such as sexual reward, cohabitation, mild stress, or even pharmacological manipulations may function as reinforcers to condition partner preferences. Evolutionary biologists and psychologists must take into consideration the idea that an individual’s experience with reward (i.e. sexual and pharmacological) can override presumably ‘innate’ mate choices (e.g. assortativeness and orientation) or mate strategies (e.g. monogamy or polygamy) by means of Pavlovian and operant contingencies. In fact, it is likely as innate to learn about the environment in ways that maximize reward and minimize aversive outcomes, making so-called ‘proximate’ causes (e.g. pleasure) ultimately more powerful predictors of social behavior and choice than so-called ‘ultimate’ causes (e.g. genetic or reproductive fitness).

To what extent, if at all, should a just society adopt public policies that regulate and limit the amount of time people work? Attempts to answer this question face a dilemma: Either, we can adopt a laissez-faire view, according to which governments must refrain from imposing working time policies on the labour market. But this view generates a situation in which many citizens experience deep regret about the balance between work and leisure in their lives. Or, we can endorse an (...) interventionist view that advocates government imposition of working time policies. However, such a view appears to be objectionably perfectionist insofar as it imposes on citizens a particular conception of the ideal balance between work and leisure. This article proposes a way out of this dilemma. It shows that the interventionist view can be defended on the anti-perfectionist grounds that this helps address a collective action problem in the labour market – the working time rat race. Employers often use working time as a proxy for their employees’ productivity and commitment. Those who work particularly long hours are often awarded benefits such as raises or promotions or are spared from dismissals. This makes it individually rational for each worker to work extra hours in an attempt to outcompete colleagues. However, if many workers pursue this strategy, it loses its effectiveness. Workers with preferences for more leisure have a claim to state intervention to remove the rat race when this doesn’t impose disproportionate harm on third parties. (shrink)

The effect of oxytocin on cognitive bias was investigated in rats in a modified conditioned place preference (CPP) paradigm. Fifteen male rats were trained to discriminate between two different cue combinations, one paired with palatable foods (reward training), and the other paired with unpalatable food (aversive training). Next, their reactions to two ambiguous cue combinations were evaluated and their latency to contact the goal pot recorded. Rats were injected with either oxytocin (OT) or saline with the (...) prediction that rats administered oxytocin would display a shorter average latency to approach on ambiguous trials. There was no significant difference between latencies to approach on ambiguous trials compared to reward trials, but the rats were significantly slower on the aversive compared to the ambiguous conditions. Oxytocin did not affect approach time; however, it was unclear, after follow-up testing, whether the OT doses tested were sufficient to produce the desired effects on cognitive bias. Future research should consider this possibility. (shrink)

BackgroundAlthough humans experience orgasms with a degree of statistical regularity, they remain among the most enigmatic of sexual responses; difficult to define and even more difficult to study empirically. The question of whether animals experience orgasms is hampered by similar lack of definition and the additional necessity of making inferences from behavioral responses.MethodHere we define three behavioral criteria, based on dimensions of the subjective experience of human orgasms described by Mah and Binik, to infer orgasm-like responses in other species: 1) (...) physiological criteria that include pelvic floor and anal muscle contractions that stimulate seminal emission and/or ejaculation in the male, or that stimulate uterine and cervical contractions in the female; 2) short-term behavioral changes that reflect immediate awareness of a pleasurable hedonic reward state during copulation; and 3) long-term behavioral changes that depend on the reward state induced by the OLR, including sexual sat...

Mature rats were kept on protein-deficient diets to test the hypothesis that late-onset protein restriction results in deficits and to determine the feasibility of doing nutrition-behavior research with old naive animals. A 3% low-protein (LP) group and a 24% adequate-protein (AP) pair-fed control were used. Body weights and plasma protein concentrations were lower and exploratory behavior and motor coordination were poorer for LP rats. Both groups preferred the 24% protein diet. LP rats habituated slower and failed to (...) overcome an initial black preference on an oddity discrimination learning task. Nutrition-behavioral research with older rats is feasible, and late-onset protein restriction produces psychobiological deficits. (shrink)

A claim about continuing technological progress plays an essential, if unacknowledged, role in the philosophical literature on “human enhancement.” I argue that—should it eventuate—continuous improvement in enhancement technologies may prove more bane than benefit. A rapid increase in the power of available enhancements would mean that each cohort of enhanced individuals will find itself in danger of being outcompeted by the next in competition for important social goods—a situation I characterize as an “enhanced rat race.” Rather than risk the chance (...) of being rendered technologically and socially obsolete by the time one is in one’s early 20s, it may be rational to prefer that a wide range of enhancements that would generate positional disadvantages that outweigh their absolute advantages be prohibited altogether. The danger of an enhanced rat race therefore constitutes a novel argument in favor of abandoning the pursuit of certain sorts of enhancements. (shrink)

This volume, Applied Social Sciences: Philosophy and Theology, provides the reader with an important set of essays related to the two aforementioned fields of study. Aesthetics plays a key role in contemporary philosophy and several authors examine its various aspects, such as the question of identification of works of art; the concept of â oesocial aestheticsâ ; the social therapeutic function that art can have; and the relationships among hermeneutics, aesthetics and communication sciences. Other papers deal with ethical issues, such (...) as the role of human values in applied ethics and moral determinations in public life. The meaning and role of postmodernism in philosophy and society is examined at length in various contributions to the volume, and the same is true for phenomenology at large. Even the theoretical seduction and practical failure of Marxism is addressed, while anthropological issues are studied with reference to truth and other key philosophical concepts. John Searleâ (TM)s theory of intentionality is seen as a factor for creating social institutions, and the real meaning of â oeglobalizationâ is investigated in another article. Many essays deal directly with theological and religious topics. For instance the alleged â oeillusionâ of religion versus its persistency is analyzed, along with the current relations between Church and civil government in Romania, the presence of different forms of Christianity in the Romanian nation, the dialogue between social theology and anthropological research, and the antinomic nature of the Church. All papers included in the volume are original and open new perspectives on the many issues addressed by the authors. Even the philosophical styles are different: hermeneutics, analytic philosophy, historical approach, postmodernism, communication theory and linguistic approach. Some papers are theoretical and others have a more empirical or historical flavour. There is however an underlying unity because they all purport to provide new ideas to professionals involved in the socio-humanistic field. The information is divided into chapters in order to help readers to form by themselves an image of the issues that are studied. However, the volume is not addressed only to specialists, and is accessible to a wider public interested in an interdisciplinary approach. (shrink)

We discover geometric properties of certain definable sets over non-Archimedean valued fields with analytic structures. Results include a parameterized smooth stratification theorem and the existence of a bound on the piece number of fibers for these sets. In addition, we develop a dimension theory for these sets and also for the formulas which define them.

It may be that one of the most important criteria of the fundamental nature of research is precisely its apparent nonobviousness, its seeming uselessness, and evident contradictoriness to common sense.

As opposed to overdemanding principles which ask individuals to sacrifice too much, there are overpermissive principles which ask individuals to sacrifice too little. Determining the extent to which one should sacrifice often comes with the need of understanding what is of moral significance. By analysing different readings of moral significance, and singling out one specific interpretation of moral significance which links moral significance to gaining or losing a considerable amount of welfare, I demonstrate that one of the well-known principles of (...) Peter Singer, the Weaker Principle of Sacrifice, is overpermissive as it exempts deliberately cultivated morally significant lavish pursuits from the domain of sacrifice. Overpermissiveness not only renders moral principles unreasonably broad but also causes burdens to be distributed unjustifiably in a comparative sense, where some parties are assigned a moral obligation whereas others are not.

Effective altruism is a movement which aims to maximise good. Effective altruists are concerned with extreme poverty and many of them think that individuals have an obligation to donate to effective charities to alleviate extreme poverty. Their reasoning, which I will scrutinise, is as follows: -/- Premise 1. Extreme poverty is very bad. -/- Premise 2. If it is in our power to prevent something very bad from happening, without thereby sacrificing anything else morally significant, we ought, morally, to do (...) it. -/- Premise 3. Individuals ought to choose the effective option in preventing very bad things. -/- Premise 4. Donating to effective charities is one of the best ways to alleviate extreme poverty. -/- Conclusion. Individuals ought to donate to effective charities working towards extreme poverty alleviation where doing so does not require them to give up anything of moral significance. -/- I will scrutinise each of these premises in turn. -/- For Premise 1, I focus on hedonistic utilitarianism and criticise its outlook on extreme poverty. I claim that hedonistic utilitarianism might be problematic for effective altruism. -/- Premise 2 is Peter Singer's Weaker Principle of Sacrifice. I introduce several possible interpretations of it, and press several objections to it by stressing overpermissiveness, luck, and rights. I defend strengthening the Weaker Principle of Sacrifice without making it overdemanding. -/- I claim that Premise 3 can be attractive to both consequentialists and non-consequentialists. Nevertheless, by showing that effectiveness sometimes violates fairness, I propose a method which avoids always helping the greater number and always giving everyone equal chances of being helped, which is compatible with effective altruism. -/- Against Premise 4, I assess the systemic change objection, which states that effective altruism unjustifiably distracts individuals from systemic change. By considering risk and the moral standing of the future extremely poor, I claim that the systemic change objection is partially successful, but cannot undermine effective altruism. -/- After analysing all of these, I argue that individuals have an obligation to donate to effective charities to alleviate extreme poverty where doing so does not require them to give up anything of moral significance.

Intentionality plays a fundamental part in human social interactions and we know that interpretation of behaviours of conspecifics depends on the intentions underlying them. Most of the studies on intention attribution were undertaken with primates. However, very little is known on this topic in animals more distantly related to humans such as birds. Three hand-reared African grey parrots were tested on their ability to understand human intentional actions. The subjects’ attention was not equally distributed across the conditions and their behavioural (...) pattern also changed depending on the condition: the parrots showed more requesting behaviours when the experimenter was unwilling to give them seeds, and bit the wire mesh more that represented the obstacle when the experimenter was trying to give them food. For the first time we showed that a bird species, like primates, may be sensitive to behavioural cues of a human according to his intentions.
